Abstract
Description
[Technical Field]
[0001] This invention relates to a technology for transforming disaster prevention actions in response to natural disasters and other disasters. [Background technology]
[0002] Traditionally, how to deal with natural disasters has been a major issue. Therefore, there has been a strong need to understand the risks of natural disasters in advance and to implement more appropriate disaster prevention actions (including disaster prevention and mitigation preparations).
[0003] As an example of technology related to such disaster prevention actions, Patent Document 1 discloses an information processing system that enables preparation for disaster prevention according to the type of natural disaster during peacetime and enables damage caused by natural disasters during emergencies. This system includes a peacetime content provision unit that provides users with content to reduce damage during emergencies when no natural disaster has been detected in the user's registered area during peacetime.
[0004] Furthermore, for example, Non-Patent Document 1 discloses a disaster prevention application that incorporates gamification when considering the use of location-based mobile game apps for disaster prevention education, designed to motivate users to learn about and understand the disaster risk in their local area. This application provides users with a local hazard map via a mobile app and is designed to award points to users who visit specific locations such as disaster-prone areas and evacuation sites.
[0005] Furthermore, Non-Patent Document 2, for example, discloses a "disaster prevention board game" application that allows residents to learn evacuation behavior during disaster-related traffic congestion on a regular basis and to learn appropriate evacuation routes that take into account the congestion that occurs during a disaster. According to this application, when heading to an evacuation center from a random starting point, it is possible to learn to take appropriate evacuation methods and routes even when heavy rain, fires, and traffic congestion are occurring. In addition, by incorporating game elements, such as competing for points among groups and conducting disaster prevention quizzes, it is possible to improve motivation to learn.

[Overview of the Initiative] [Problems that the invention aims to solve]
[0008] To further encourage disaster preparedness actions among those targeted for disaster preparedness promotion, a mechanism is needed to help these individuals recognize disasters as their own risk, internalize disasters, and become aware of the need to take disaster preparedness actions on a daily basis.
[0009] In this regard, the technologies disclosed in Patent Document 1, Non-Patent Document 1, and Non-Patent Document 2 mentioned above make it possible to raise the disaster prevention awareness of the target individuals during peacetime. However, even with these technologies, it remains difficult to address the problem of the "risk perception paradox," in which individuals recognize the importance of disaster prevention but ultimately fail to take disaster prevention action.
[0010] It has been pointed out that the perception of costs and benefits is a factor in this risk perception paradox. Humans inherently have a tendency to overestimate present events and underestimate future events (present bias). On the other hand, disaster prevention actions are structured in such a way that costs such as expenses and effort are paid in the present, and the benefit of securing safety is received in the future. As a result, due to present bias, the perceived cost in the present becomes greater than the perceived benefit, leading to the risk perception paradox where no action is taken.

[0027] Embodiments of the present invention will be described in detail below with reference to the drawings.
[0028] [Disaster Prevention Action Promotion Devices / Systems] Figure 1 is a functional block diagram showing the functional configuration of one embodiment of a disaster prevention action promotion device according to the present invention.
[0029] The disaster prevention action promotion device 1 of this embodiment, shown in Figure 1, is a device that provides "action suggestion information" encouraging the implementation of disaster prevention actions to a predetermined target (hereinafter sometimes abbreviated as "target") who should be encouraged to take "disaster prevention actions" in a broad sense, including disaster prevention and mitigation preparations, thereby encouraging the target to take disaster prevention actions.
[0030] In order to provide such "action suggestion information" to the target audience, the disaster prevention action promotion device 1 specifically: (A) A behavioral principle generation unit 121 that uses at least one of the subject's survey response data, posted data, and dialogue data, and based on the information related to monetary amounts and / or time extracted from said at least one, generates "cost-benefit information" relating to at least one of the subject's perceived cost (burden) and perceived benefit (feeling of gaining profit or reward) for taking disaster prevention actions, (B) An action promotion plan generation unit 122 generates an action promotion plan for the subject, which includes data linking the disaster prevention action items and the priority, using a plurality of pre-set "disaster prevention action items," each of which is pre-associated with information related to costs and / or time required, and the subject's "cost-benefit perception information," to determine the "priority" to propose to the subject for each of the plurality of "disaster prevention action items," and the action promotion plan generation unit 122 generates an action promotion plan for the subject, which includes data linking the "disaster prevention action items" and the "priority," (C) The Action Promotion Intervention Unit 123 determines the "disaster prevention action items" related to disaster prevention actions to be proposed to the subject using the "priority" included in the subject's "action promotion plan," and provides the subject with "action proposal information" that encourages disaster prevention actions related to the determined "disaster prevention action items." It has.
[0031] Here, the "cost-benefit information" generated in (A) above can be information relating to the limits of expenses and / or time required for the actions taken by the target person, such as those that do not have a perceived cost, have a perceived benefit, or whose perceived benefit exceeds the perceived cost. Specifically, the "cost-benefit information" may include, for example, (a) “The upper limit on the costs incurred for disaster prevention actions,” which is the upper limit on the costs that, if the costs are below this limit, the person concerned can take disaster prevention actions with a sense of benefit, or with a sense of benefit that outweighs the cost. (b) “Maximum time required for disaster prevention actions” and the maximum time within which the person concerned can take disaster prevention actions without feeling the cost, with a sense of benefit, or with a sense of benefit that outweighs the cost, and (c) Of the "costs incurred in disaster prevention actions" and "time required for disaster prevention actions," which information is more likely to be perceived as costly, less likely to be perceived as beneficial, or more likely to be perceived as costly than beneficial? At least one of them, preferably all of them, may be included.
[0032] As a simple example, if the determined "cost-benefit perception information" includes information that "the target person perceives a cost as high if the cost of disaster prevention action is 2,000 yen or more," the action promotion intervention unit 123 can, for example, provide the target person with "action suggestion information" related to disaster prevention action that does not exceed 2,000 yen, with a higher "priority" than "action suggestion information" related to disaster prevention action that does exceed 2,000 yen. In this case, it becomes possible to resolve the "risk perception paradox" problem, where "the target person recognizes the importance of disaster prevention but ultimately does not take disaster prevention action." Thus, the disaster prevention action promotion device 1 can encourage the target person to take disaster prevention action based on the target person's "cost-benefit perception information" related to the risk perception paradox.
[0033] Furthermore, the disaster prevention action promotion device 1 of this embodiment is (D) For each of the multiple target candidates who are candidates for the above-mentioned target persons (specified targets), a risk perception paradox score determination unit 113 determines the target candidate's "risk perception paradox score" based on the "willingness to act score" and "action implementation score" determined based on at least one of the target candidate's questionnaire response data, posting data, dialogue data, and disaster prevention-related action data, and compares the "willingness to act score," which relates to whether the target candidate intends to act on each of the multiple pre-set "disaster prevention action items," with the "action implementation score," which relates to whether the target candidate has taken action on each of the multiple "disaster prevention action items." (E) A target risk score determination unit 114 that determines a "target risk score" indicating the magnitude of the risk to the disaster for the target candidate, based on at least the "risk perception paradox score", (F) Based on the "target risk score" determined for each of the multiple target candidates, the action promotion target determination unit 115 determines the above-mentioned target persons (predetermined targets) from among these multiple target candidates who should be encouraged to take disaster prevention action. It also possesses.
[0034] Thus, the disaster prevention action promotion device 1 of this embodiment also functions as a disaster prevention action promotion target determination device capable of determining targets for which disaster prevention actions should be encouraged, based on information related to the risk perception paradox, specifically the "willingness to act score" and the "action implementation score" (or "risk perception paradox score").
[0035] In this embodiment, and in the following description as well, the disasters assumed by disaster prevention actions (including disaster preparation) are natural disasters, but the disasters according to the present invention are not limited to these. That is, any disaster event from which the "cost-benefit information" described in (A) above can be obtained can also be considered a disaster according to the present invention, such as various accidents, crimes, or wars.
[0036] Furthermore, while the disaster prevention action promotion device 1 of this embodiment is configured to include the action principle generation unit 121 described in (A), the action promotion plan generation unit 122 described in (B), and the action promotion intervention unit 123 described in (C), the configuration of the present invention is not limited thereto. That is, at least one of these functional components may be a functional component of another device. For example, the action principle generation unit 121 and the action promotion plan generation unit 122 may be included in a server, and the action promotion intervention unit 123 may be included in a terminal that receives the action promotion plan from this server.
[0037] Furthermore, the disaster prevention action promotion device 1 of this embodiment is configured to include the risk perception paradox score determination unit 113 (D) above, the target risk score determination unit 114 (E) above, and the action promotion target determination unit 115 (F) above, but the configuration of the present invention is of course not limited to this. For example, at least one of these functional components may be a functional component of another device. Also, the risk perception paradox score determination unit 113, the target risk score determination unit 114, and the action promotion target determination unit 115 may be functional components of a disaster prevention action promotion target determination device, which is a separate device from the disaster prevention action promotion device 1. In any case, in these cases, the entire device, including device 1 and the other device, can be considered as the disaster prevention action promotion system according to the present invention.
[0038] [Device Functional Configuration, Disaster Prevention Action Promotion Program] The functional configuration of the disaster prevention action promotion device 1 according to the present invention will be described in more detail below. In the functional block diagram of Figure 1, the disaster prevention action promotion device 1 includes a communication interface unit 101, a target positioning information storage unit 102, a local government disaster information storage unit 103, a target information storage unit 104, a user interface (UI) unit 105, and a processing unit equipped with an IC (Integrated Circuit) such as a processor and various memories.
[0039] The processing unit has computer (arithmetic processing) functions and in this embodiment functions as a communication control unit 131 including an exposure score determination unit 111, a vulnerability score determination unit 112, a risk perception paradox score determination unit 113, a target risk score determination unit 114, an action promotion target determination unit 115, an action principle generation unit 121, an action promotion plan generation unit 122, an action promotion intervention unit 123, and a completion notification acquisition unit 131a.
[0040] These functional components may also be realized by executing an embodiment of the disaster prevention action promotion program according to the present invention, which is stored in the processing unit. In other words, one embodiment of the disaster prevention action promotion program according to the present invention may involve a computer functioning as these functional components. Furthermore, at least a portion of these functional components may be implemented using wired logic. The processing flow shown by connecting the functional components of the disaster prevention action promotion device 1 with arrows in the functional block diagram of Figure 1 can also be understood as one embodiment of the disaster prevention action promotion method according to the present invention.
[0041] Here, the disaster prevention action promotion device 1 of this embodiment may be a cloud server, a non-cloud server, or even a dedicated device for promoting disaster prevention actions, but it can also be, for example, a personal computer (PC), a notebook or tablet computer, or a smartphone equipped with the disaster prevention action promotion program according to the present invention.
[0042] The following will provide a detailed explanation of each functional component in this embodiment described above. As a premise, the multiple target candidates, who are candidates for those who should be encouraged to take disaster prevention actions, i.e., for whom action suggestion information should be provided (predetermined targets), are the users of terminal 2 in this embodiment. Furthermore, in the following explanation, unless otherwise specified, the type of disaster related to disaster prevention actions will be water damage (floods, river overflows, etc.). Of course, the following explanation also applies to other types of disasters such as earthquakes and fires.
[0043] <Means for determining exposure score> Similarly, in the functional block diagram of Figure 1, the exposure score determination unit 111 of this embodiment is (a) Based on the acquired information relating to the location of user u (of terminal 2), from among multiple areas included in a predetermined region (e.g., the whole country or each prefecture), select the area j(n) where the information relating to the user's stay satisfies the predetermined conditions. u Determine which one to be: (b) Determined accommodation area (j=1,2,··,n u For each user, the proportion of time spent in the area j is related to the stay ratio information W. u,j We decided, (c) Based on the acquired data on the occurrence of disasters, a determination is made as to whether the area of residence j is a disaster area with a high frequency of occurrence of disaster i (which is the target of disaster prevention), and the result of this determination is shown in disaster area determination information B. i,j And the determined information on the proportion of stay W u,j Based on this, the exposure score E indicates the likelihood of user u being exposed to disaster. u,i To decide.
[0044] Of these, the information relating to the location of user u in (a) above can be, for example, GPS (Global Positioning System) positioning information (or connection sector information (location registration information)) of user u's terminal 2, which is acquired from the positioning information management server 3 managed by the telecommunications carrier via the communication interface unit 101 and the communication control unit 131 and stored in the target positioning information storage unit 102. Furthermore, as multiple areas included in the predetermined region, a quarter-regional mesh (an area of approximately 250m square) as defined by the Statistics Bureau of the Ministry of Internal Affairs and Communications can be adopted. In this embodiment, the data transmitted from the positioning information management server 3 and stored in the target positioning information storage unit 102 includes the positioning date and time for user u's terminal 2, the position as a result of positioning in units of regional mesh, and the time spent at said location (mesh).
[0045] Furthermore, the staying area j in (a) above can be an area (mesh) where the staying time of the terminal 2 of the user u is longer than a predetermined time (for example, 15 minutes). Of course, it is also possible to determine the staying area j using other known methods for determining movement and staying based on GPS positioning data. Also, the staying ratio information W in (b) above u,j uses a predetermined staying observation period as T, and the cumulative staying time in the staying area j as t u,j Then, the following formula (1) W u,j = t u,j / T can be calculated by
[0046] Furthermore, in this embodiment, the data related to the occurrence of the disaster in (c) above is statistical data on natural disasters that have occurred in each prefecture, which is transmitted from the local government's disaster information management server 3 and stored in the local government's disaster information storage unit 103, and is published by the country, local governments, or predetermined organizations, etc. (including information related to the specified disaster area). For example, when the disaster type i is a flood, it is also preferable to use the inundation assumption area information in the national numerical information. Also, the disaster area determination information B in (c) above i,j can be information on whether the staying area j of the user u is included in the disaster area related to the disaster i. In this embodiment, when the staying area j is included in the disaster area related to the disaster i, B i,j = 1, and when it is not included, B i,j = 0
[0047] Finally, the exposure score E in (c) above u,i is the following formula (2) E u,i = Σ j (W u,j × B i,j ) Here, Σ j is the sum for j (= 1, 2, ···, n u ) and can be calculated by. In this case, the exposure score E u,i represents the ratio of the time the user u stays within the disaster area
[0048] Figure 2 is a table showing one embodiment of the exposure score determination process by the exposure score determination unit 111.
[0049] In this embodiment shown in Figure 2, the exposure score determination unit 111 determines the area exposure score (W) for each of the 21 areas (j=1,2,··,21) where the determined user u stays. u,j ×B i,j By calculating () and summing these for j, the exposure score E of user u is obtained. u,i The value determined is (=0.55).
[0050] In this embodiment, the area type of each accommodation area j is also determined. For example, the area types of accommodation area 1 and accommodation area 4 are "home" and "hospital," respectively. In this embodiment, during the accommodation observation period T, the area (mesh) where the user stayed the longest at night (e.g., 19:00-3:00) is designated as "home," and the area types of accommodation areas (mesh) other than "home" are determined using separately acquired map information. According to Figure 2, user u stayed for roughly the same amount of time at both home and the university, but home is located in a disaster area while the university is not. Therefore, user u's exposure score E u,i It is understood that the value is influenced by the amount of time spent at home rather than at the university.
[0051] As mentioned above in this embodiment, the type of disaster related to disaster prevention actions is flooding, therefore, the exposure score E of user u is as follows: u,i (Disaster i is "flood"), easily, exposure score E u This is how it is written.
[0052] <Method for determining vulnerability score> Returning to the functional block diagram in Figure 1, the vulnerability score determination unit 112 of this embodiment determines a vulnerability score V indicating the vulnerability that user u has when responding to a disaster (flood in this embodiment) based on the acquired information relating to at least one of the following for user u (of terminal 2): "attributes," "insurance," "living environment," and "living area." u To decide.
[0053] In this embodiment, the information relating to user u's "attributes," "insurance," "living environment," and "living area" is user u's response to the disaster preparedness questionnaire. This disaster preparedness questionnaire can be administered either by displaying it on terminal 2, which receives the disaster preparedness questionnaire data, or by using a questionnaire sheet.
[0054] Figure 3 is a table showing one embodiment of the vulnerability score determination process by the vulnerability score determination unit 112.
[0055] In the embodiment shown in Figure 3, the vulnerability score determination unit 112 determines the user u's response score for each of the four items: "evacuation response capability," "disaster response capability," "residential response capability," and "community response capability," based on the user u's "answers" to the "questions" in the disaster preparedness questionnaire, and then calculates the vulnerability score V from the z-score value obtained by converting each determined response score. u They have made the decision.
[0056] Regarding the "Evacuation Response Capability" item, the response score is determined based on the user's "answer" to the "question" about user u's attributes, "Are there any cohabitants who would have difficulty evacuating alone?". If the answer is "Yes: Item score = 1", the response score is set to 1, and if the answer is "No: Item score = 0", the response score is set to 0. In this example, the response score is 0. Similarly, for the "Disaster Response Capability" item, the response score is determined based on the user's "answer" to the "question" about user u's insurance (earthquake insurance (including flood damage coverage), fire insurance (including flood damage coverage), and contents insurance). In this example, the response score is 1. Furthermore, for the "Residential Response Capability" item, the response score is determined similarly for each of the "answers" to the four "questions" (one of the five is not used) about user u's living environment. In this example, these response scores are 1, 0.5, 0.5, and 0, respectively.
[0057] Furthermore, for the "Regional Responsiveness" item, the response score is similarly determined based on the user's "answers" to "questions" about the user's residential area. In this example, this response score is 1. The response scores described above take values from 0 to 1, and in all cases, a higher value indicates a higher level of vulnerability. Also, vulnerability score V u The "answers" to the questions "age," "gender," and "ownership type of the house in which the user resides" (Figure 3), which were not used in the decision, may be linked as supplementary information to a later generated (potential) action plan for this user u (Figure 9).
[0058] Next, in this embodiment, the vulnerability score determination unit 112 determines the above-mentioned response score v k For each of (k=1, 2, ..., 7), the following equation (3) vs k =0 :(v k If -μ) / σ < 0 =(v k -μ) / σ :0≦(v k In the case of -μ) / σ Therefore, z-scored response scores vs k Calculate these answer scores vs k The average value of vulnerability score V u (0≦V u ) is determined. In this example, the vulnerability score is V u The result is 0.59. Here, in equation (3) above, μ and σ are the mean and standard deviation of the response scores, respectively, which were calculated as statistical data (after determining the above response scores for a large number of users in advance). The vulnerability score V determined in this way u The larger the value (positive value), the higher the vulnerability of user u.
[0059] <Method for determining the risk perception paradox score> Returning to the functional block diagram in Figure 1, the risk perception paradox score determination unit 113 of this embodiment determines the user's risk perception paradox score P based on the comparison result between an "action intention score" which indicates whether user u has the intention to act on each of the pre-set disaster prevention action items, and an "action execution score" which indicates whether user u has acted on each of these disaster prevention action items. u To decide.
[0060] Here, the risk perception paradox score P u This is the exposure score E that has already been explained. u and vulnerability score V u Similarly, this is a user-specific score and represents the magnitude of the gap between subjective and objective perceptions for user u.
[0061] Furthermore, the "intention to act score" and "action implementation score" mentioned above are determined based on at least one of the following: user u's survey response data, posted data, dialogue data, and disaster prevention-related action data. Specifically, as will be described later, the "intention to act score" and "action implementation score" can be determined by a disaster prevention awareness survey conducted by displaying the survey content on terminal 2 that receives the disaster prevention awareness survey data (or by using a disaster prevention awareness survey form), or by using a pre-trained machine learning model.
[0062] Figure 4 is a schematic diagram showing one embodiment of the risk perception paradox score determination process using the disaster prevention awareness questionnaire method by the risk perception paradox score determination unit 113. Here, the user's "response" to the disaster prevention awareness questionnaire (from terminal 2) is acquired from the questionnaire / registration information management server 5 (Figure 1) via the communication interface 101 (Figure 1) and the communication control unit 131 (Figure 1), and stored in the target information storage unit 104 (Figure 1).
[0063] In this embodiment shown in Figure 4, the risk perception paradox score determination unit 113 first asks the first "question" <Q1. Questions regarding perception and intention>: "Regarding each of Disaster Prevention Actions 1 to 9, how often do you usually think you will carry them out? Please select the most appropriate option." Obtain, from the target information storage unit 104, the "answer" to , which is "the selection result of one of 'think so' and 'don't think so' for each disaster prevention action item (1 to 9)". Here, regarding each disaster prevention action item (1 to 9), if "think so" is selected, the action will score of the disaster prevention action item is set to 1, and if "don't think so" is selected, the action will score of the disaster prevention action item is set to 0.
[0064] Also, the risk perception paradox score determination unit 113 is the second "question", which is <Q2. Questions regarding actions>: "Regarding each of Disaster Prevention Actions 1 to 9, how often have you carried them out in the past two or three years? Please select the most appropriate option." Obtain, from the target information storage unit 104, the "answer" to , which is "the selection result of one of 'carried out' and 'not carried out' for each disaster prevention action item (1 to 9)". Here, regarding each disaster prevention action item (1 to 9), if "carried out" is selected, the action implementation score of the disaster prevention action item is set to 1, and if "not carried out" is selected, the action implementation score of the disaster prevention action item is set to 0.
[0065] Next, the risk perception paradox score determination unit 113 compares the action will score and the action implementation score for each disaster prevention action item (1 to 9). As shown in the table of FIG. 4, when the action will score is 1 and the action implementation score is 0, the paradox score of the disaster prevention action item is set to 1, and in other cases, the paradox score of the disaster prevention action item is set to 0. That is, regarding the disaster prevention action item, only when the user who is the questionnaire respondent "thinks they will carry it out but has not carried it out", it is considered that a risk perception paradox has occurred, and the paradox score is set to 1.
[0066] Finally, the risk perception paradox score determination unit 113 calculates the user u's risk perception paradox score P based on the average of the user u's paradox scores (0 or 1) for these disaster prevention action items 1 to 9. u In this embodiment, as shown in Figure 5 which will be explained later, the paradox score for each disaster prevention action item (1-9) is all 1, and as a result, the risk perception paradox score P u It is set to 1.
[0067] Furthermore, as a change mechanism, if the average value of user u's paradox score (0 or 1) in disaster prevention action items 1-9 is equal to or greater than a predetermined threshold (e.g., 0.5), the risk perception paradox score P will be changed. u We can set this threshold to 1, and anything below this threshold to 0. Alternatively, this threshold may be set to, for example, (μ + 2 × σ). Here, μ and σ are the mean and standard deviation of the average paradox score, respectively, calculated as statistical data (after first determining the average value of the paradox score for disaster prevention action items 1 to 9 for a large number of users).
[0068] The above describes the risk perception paradox score P using the disaster preparedness awareness questionnaire method. u The decision-making process was explained, but the risk perception paradox score P u This can also be derived using, for example, a machine learning model. Specifically, for example, the correct values for "action intention score" and "action implementation score" can be determined from survey response data from a large number of users, and at least one of the following data from the user can be used as training data: social media posting data, AI (LLM (Large Language Models)) chatbot interaction data, and behavioral data related to stays at "home," "hospitals," "commercial facilities," etc. A pre-trained score estimation model can be generated using, for example, the SVDD (Support Vector Data Description) algorithm. By using this pre-trained model, the "action intention score" and "action implementation score" for each disaster prevention action item of user u can be determined, thereby generating the risk perception paradox score Pu This becomes possible to decide.
[0069] <Method for determining target risk score> Returning to the functional block diagram of Figure 1, the target risk score determination unit 114 of this embodiment determines the exposure score E u And, vulnerability score V u And the risk perception paradox score P u Based on this, the target risk score R indicates the magnitude of the user u's risk to disasters (flood in this embodiment). u To decide.
[0070] As mentioned above, the risk perception paradox score P u The target risk score R is derived solely from user u. u For example, determining the user u's risk perception paradox score P. u The target risk score R is used as is. u It is also possible to do so. However, in this embodiment, the risk to disasters specific to user u is sufficiently targeted to the risk score R. u To reflect this, the target risk score determination unit 114 determines the exposure score E u Vulnerability score V u , and the risk perception paradox score P u Using all of the above, the target risk score R u They have made the decision.
[0071] Figure 5(A) is a table showing one embodiment of the target risk score determination process by the target risk score determination unit 114.
[0072] In this embodiment shown in Figure 5(A), the target risk score determination unit 114 determines the risk perception paradox score P u (=1), exposure score E u (=0.55), and vulnerability score V u The sum of (=0.59) is used for the target risk score R u (=2.14) is used here. The risk perception paradox score P uAs mentioned above, (=1) represents the average paradox score of the disaster prevention action items (1-9).
[0073] Of course, the target risk score R u The calculation of (=2.14) is not limited to the sum of the above. Target risk score R u However, the risk perception paradox score P u Exposure score E u , and vulnerability score V u If each of them is a monotonically increasing function, then various other target risk scores R u The calculation method can be adopted.
[0074] Furthermore, as a change in the manner of modification, the target risk score determination unit 114 changes the exposure score E u and vulnerability score V u A combined score, for example, exposure score E u and vulnerability score V u The combined score (E u +V u For users (of terminal 2) whose risk perception paradox score P is large enough to satisfy a predetermined condition, for example, to be greater than or equal to a predetermined threshold (e.g., 1), the risk perception paradox score P is calculated only for those users. u Exposure score E u , and vulnerability score V u Using the target risk score R u It is also preferable to calculate the exposure score E. In this case, the user (of terminal 2) as a candidate for the person who should be encouraged to take disaster prevention action is given an exposure score E. u and vulnerability score V u The results will narrow down (limit) the options.
[0075] <Means for determining targets for behavioral promotion> Returning to the functional block diagram in Figure 1, the action promotion target determination unit 115 of this embodiment determines the target risk score R for each user (of terminal 2) who is a candidate for a person who should be encouraged to take disaster prevention action. uBased on this, among these users, the target individuals (predetermined targets) for whom disaster prevention actions should be promoted are determined. Specifically, as shown in FIG. 5(A), the action promotion target determination unit 115 determines the target risk score R u for users for whom the target risk score R
[0076] is equal to or greater than a predetermined threshold Th (for example, 1.5) as the target individuals (predetermined targets) for whom disaster prevention actions should be promoted. u , vulnerability score V u , and risk perception paradox score P u to determine the target risk score R u , and the action promotion target determination unit 115 may determine the target individuals (predetermined targets) for whom disaster prevention actions should be promoted based on this determined target risk score R u .
[0077] FIG. 5(B) is a schematic diagram for explaining the above-described modified aspect in the target risk score determination process and the action promotion target determination process.
[0078] The graph shown in FIG. 5(B) shows the state of distribution in the xy coordinate space of the score vector x u for a large number of users, where the combined score (E u +V u ) of the exposure score E u and the vulnerability score V u is taken as x and the risk perception paradox score P → is taken as y. This distribution is a bivariate normal distribution, and it is assumed that the variables x and y are correlated (p>0).
[0079] Also, on the right side of the graph in FIG. 5(B), the expression representing this distribution: f(x → )=··· is shown. In this expression, Σ is the covariance matrix, exp is the exponential function, and μ → is (μ x , μ y ). Here, μ x and μy Each of these is x(combined score(E u +V u )) mean and y (risk perception paradox score P u This is the average of ).
[0080] The target risk score determination unit 114 determines the user u's score vector x → If the coordinate position (=(x, y)) falls within the predefined "risk area" in the graph of Figure 5(B), the target risk score R for this user u is determined. u If it is not included, the target risk score R for this user u is set to 1. u Set to 0. Next, the action promotion target determination unit 115 determines the target risk score R in this way. u (x → Users whose coordinate position is within the risk area can be designated as individuals (specified targets) who should be encouraged to take disaster prevention actions.
[0081] <Action principle generation means> Returning to the functional block diagram in Figure 1, the action principle generation unit 121 of this embodiment uses at least one of the following: survey response data, social media posting data, and dialogue data with an AI (LLM) chatbot, etc., from target persons (predetermined targets) who should be encouraged to take disaster prevention action, as determined by the action promotion target determination unit 115. Based on at least one of the following extracted from the at least one: "information related to monetary amount" and "information related to time," or both in this embodiment, the unit generates "cost-benefit perception information."
[0082] Here, the extraction of "information related to monetary amounts" and / or "information related to time" can be performed by text mining or reinforcement learning through a disaster prevention cost questionnaire that is displayed on terminal 2 that receives the disaster prevention cost questionnaire data (or using a questionnaire form).
[0083] Furthermore, the "cost-benefit information" refers to information relating to at least one of the following for the subject when carrying out disaster prevention actions: "cost limits" and "time limits," or both in this embodiment, which indicate that the subject does not perceive a cost, does perceive a benefit, or the benefits outweigh the costs. This information can be considered as the behavioral principle for the subject's disaster prevention actions.
[0084] Specifically, the "cost-benefit information" of the target individuals may consist of the following three items: (a) A "cost limit" for disaster prevention actions, which means that if the cost is below this limit, the person concerned can take disaster prevention actions without feeling the cost burden. (i) The "maximum time limit" required for disaster prevention actions, which, if the time limit is less than or equal to that limit, allows the person concerned to take disaster prevention actions without feeling the cost. (c) Of the costs and time required for disaster prevention actions, the information that is easier to perceive as cost is "information relating to either (cost or time)".
[0085] Figure 6 is a table illustrating one embodiment of the process by which the Behavioral Principle Generation Unit 121 generates cost-benefit information (behavioral principles) using the disaster prevention cost questionnaire method. Specifically, this table shows the content of the "questions" and "answers" from the disaster prevention cost questionnaire that was conducted. Here, the "answers" of the target person (the user of terminal 2) are acquired from the questionnaire / registration information management server 5 (Figure 1) via the communication interface 101 (Figure 1) and the communication control unit 131 (Figure 1), and stored in the target information storage unit 104 (Figure 1).
[0086] In this embodiment shown in Figure 6, the behavioral principle generation unit 121 acquires response data from the subjects to questions related to each item (emotion, risk perception, social capital, norms, lifestyle habits, financial sense, time sense, burden) in the disaster prevention cost questionnaire. Next, from the response data to the question related to the item "financial sense," the "upper limit of expenses" in (a) above is determined to be "2,000 yen." Also, from the response data to the question related to the item "time sense," the "upper limit of time" in (b) above is determined to be "60 minutes (1 hour)." Furthermore, from the response data to the question related to the item "burden," the "information related to either cost or time" in (c) above is determined to be "time." As a result, the behavioral principle generation unit 121 generates "cost-benefit information" (upper limit of expenses: 2,000 yen, upper limit of time: 1 hour, priority: time).
[0087] Incidentally, the responses (data) to the questions related to the remaining items (emotions, risk perception, social capital, norms, and lifestyle) can also be used in the subsequent behavioral promotion plan generation and behavioral promotion intervention processes. However, here they serve as a guide to elicit appropriate "cost limits," "time limits," and "information related to either cost or time" that are appropriate to the individual's circumstances.
[0088] Furthermore, as a way to modify the questions, the "Financial Sense" item could be changed to, for example, "At what point do you think you would lose the sense of benefit from disaster preparedness actions?" or "At what point do you think you would feel the cost outweighs the benefit from disaster preparedness actions?" Similarly, the "Time Sense" item could be changed to, for example, "At what point do you think you would lose the sense of benefit from disaster preparedness actions?" or "At what point do you think you would feel the cost outweighs the benefit from disaster preparedness actions?"
[0089] Figure 7 is a table illustrating one embodiment of the cost-benefit information (behavioral principle) generation process using text mining by the behavioral principle generation unit 121. Specifically, this table shows the "posting time" and "post content" of a post sent by a target user (poster ID: 00269) on a certain SNS, the "keywords" extracted from the "post content," and the "estimated emotion" estimated from these "keywords." Here, the "posting time" and "post content" of this target user (a user of terminal 2) are acquired from an SNS server (not shown) via the communication interface 101 (Figure 1) and the communication control unit 131 (Figure 1), and stored in the target information storage unit 104 (Figure 1).
[0090] In this embodiment shown in Figure 7, the behavioral principle generation unit 121 acquires the content data of posts made by the target person (poster ID: 00269), extracts keywords related to money (amount) and keywords related to time (time) (word information related to money and word information related to time) from this content data using known text mining, and estimates the emotions of the target person (the poster) regarding the extracted keywords. In this embodiment, the acquired posts are not limited to those containing content about disasters, but the posts include content in which the poster expresses and reveals their own sense of money and time.
[0091] In this embodiment, for emotion estimation, the Emotion Expression Dictionary (edited by Akira Nakamura, 1993) is applied to the extracted keywords related to money and time as described above to determine one of 10 emotions (sadness, disgust, relief, fear, excitement, goodness, joy, surprise, anger, shame) as the estimated emotion of the subject. Next, the behavioral principle generation unit 121 arranges the subject's posts associated with the estimated emotion in chronological order using posting time data, and aggregates the number of posts on each date t during the aggregation period T (in this embodiment, October 1st to October 31st, 2024) for each of the subject's emotion imp, and calculates the posting frequency freq by emotion and date. (5) freq=freq(imp, t| imp∈IMP, t∈T) This generates IMP, where IMP is a set of 10 emotions (IMP = {sadness, disgust, relief, fear, excitement, happiness, joy, surprise, anger, shame}).
[0092] Next, the behavioral principle generation unit 121 uses the generated emotion- and date-specific posting frequency freq to determine the most frequently occurring amount and time during the aggregation period T, and sets these as the "cost limit" and "time limit" included in the "cost-benefit information," respectively.
[0093] Specifically, the frequency of occurrence of the extracted money-related keywords wi as sentiment imp on date t is calculated as wi imp,t The frequency of occurrence of the extracted money-related keywords wi as sentiment imp during the aggregation period T is then calculated as wi * imp The monetary score Score_C(imp, t, wi) for the keyword wi related to money, with date t and sentiment imp, is calculated using the following formula: (6) Score_C(imp, t, wi)=wi imp,t / wi * imp ×log(wi imp,t ) The time score is calculated using the extracted time-related keyword "wi" and calculated in the same manner as above. Incidentally, these scores are set based on the word scores used in the construction of LIWC (Linguistic Inquiry and Word Count) (Daisaku Shibata, 2017).
[0094] Finally, the behavioral principle generation unit 121 sets the amount associated with the keyword with the largest sum of monetary scores Score_C for all emotional impressions during the aggregation period T as the "cost limit" included in the "cost-benefit information". Similarly, the time associated with the keyword with the largest sum of time scores Score_T for all emotional impressions during the aggregation period T is set as the "time limit" included in the "cost-benefit information". Alternatively, it is also preferable to determine the "cost limit" and "time limit" by summing the monetary score Score_C and time score Score_T when the emotional impression is a negative emotion, namely sadness, disgust, fear, anger, and shame.
[0095] Figure 8 is a table illustrating another embodiment of the cost-benefit information (behavioral principle) generation process using text mining by the behavioral principle generation unit 121. Specifically, this table shows the "transmission time" and "transmission content" of the dialogue data transmitted by both parties in a conversation between a certain AI(LLM) chatbot and a target person, as well as "keywords" related to money and "keywords" related to time extracted from this "transmission content," and the "estimated emotion" estimated from these "keywords." Here, the "transmission time" and "transmission content" of both parties are acquired from the AI(LLM) chatbot server (not shown) via the communication interface 101 (Figure 1) and the communication control unit 131 (Figure 1), and stored in the target information storage unit 104 (Figure 1).
[0096] In this embodiment, it is also preferable that the conversation with the AI(LLM) chatbot be set up to begin with a normal greeting and then develop into a discussion of topics related to recent disaster cases, past disaster cases, and preparedness and readiness for disasters, using a publicly known AI(LLM) conversational information provision technology.
[0097] In this embodiment shown in Figure 8, the behavioral principle generation unit 121 acquires data on the content of the subject's communication, extracts keywords related to money (amount) and keywords related to time (time) (word information related to money and word information related to time) from this communication data by text mining, and estimates the emotions of the subject (the sender) regarding the extracted keywords. Next, the behavioral principle generation unit 121 uses the emotions estimated from the subject's utterances to calculate the monetary score Score_C for the money-related keywords and the time score Score_T for the time-related keywords, in the same manner as the method described using Figure 7, and determines the "cost limit" and "time limit" to be included in the "cost-benefit perception information" based on these.
[0098] The above describes an example of determining "cost-benefit information" from SNS post content data and AI (LLM) chatbot dialogue data using Figures 7 and 8. However, in these cases, the disaster prevention action promotion device 1 may be included in terminal 2 (e.g., a smartphone or PC) and used by the target person (the user), and may directly exchange posts with the SNS server or directly interact with the AI (LLM) chatbot server.
[0099] <Method for generating action-promoting plans> Returning to the functional block diagram in Figure 1, the action promotion plan generation unit 122 of this embodiment uses a plurality of pre-set disaster prevention action items and the target person's cost-benefit perception information (determined by the action principle generation unit 121) to determine the "priority" for each of these disaster prevention action items when proposing them to the target person, and generates an "action promotion plan" for the target person that includes data linking the disaster prevention action items and the "priority".
[0100] Here, each of the multiple disaster prevention action items is pre-linked with at least one of the following: information related to costs (for example, information that the cost will be 2,000 yen) and information related to the time required (for example, information that the time required will be 1 hour). In this embodiment, both of these are pre-linked. Furthermore, the "action promotion plan" in this embodiment includes data that links the disaster prevention action item with information related to the location where the disaster prevention action related to that action item will be performed (for example, information that the disaster prevention action will be performed at home or outside), and the determined "priority."
[0101] Figure 9 is a schematic diagram showing one embodiment of the action promotion plan generation process by the action promotion plan generation unit 122.
[0102] In this embodiment shown in Figure 9, the action promotion plan generation unit 122 generates an action plan for each of the nine set disaster prevention action items. (a) Information regarding whether the disaster prevention action related to the item will be carried out only once or on a continuous basis. (b) Information regarding whether the disaster prevention action related to the item will be carried out at home or outside the home, (c) Time required for disaster prevention actions related to the item, (d) Costs incurred for disaster prevention actions related to the item in question, (e) Standardization time: The time required for disaster prevention actions related to the item in (c) above, standardized to a time limit of 1 (included in the determined cost-benefit information), and (f) Standardized cost: The cost of disaster prevention actions related to the item in (d) above, standardized with a cost limit of 1 (included in the determined cost-benefit information). It generates linked information.
[0103] In this example, the time limit set for the target person is 1 hour. As a result, the standardized time required for the disaster prevention action item: "Confirming the location of the nearest evacuation shelter on a map" is 0.1 (=0.1 / 1), since the required time is 0.1 hours. Also, the cost limit set for the target person is 2,000 yen. As a result, the standardized cost for the disaster prevention action item: "Subscribing to flood insurance and household contents insurance" is 5 (=10000 / 2000), since the actual cost is 10,000 yen.
[0104] Next, the action promotion plan generation unit 122 determines the "overall cost-benefit score" for each disaster prevention action item by summing the standardization time in (e) above and the standardization cost in (f) above. That is, the following formula (7) (Overall cost-benefit score) = (Standardization time) + (Standardization cost) This is used to calculate the "overall cost-benefit score." Finally, priority numbers (1, 2, 3, ...) are assigned to these disaster prevention action items in ascending order of the determined "overall cost-benefit score," and an action promotion plan for the target person is generated, linking the priority number to each disaster prevention action item. In this embodiment, the disaster prevention action item with the smallest overall cost-benefit score of 0.1, "Confirming the location of the nearest evacuation shelter on a map," is assigned priority 1, and suggested information on disaster prevention actions related to this action item will be provided to the target person with the highest priority in subsequent action promotion interventions.
[0105] In this embodiment, the "cost-benefit perception information" that indicates "which of cost and time is more likely to be perceived as cost-effective" is not used to determine priorities, but it is also possible to use this information to determine priorities. For example, if a subject's "cost-benefit perception information" includes the information that "time is more likely to be perceived as cost-effective," then the subject's "overall cost-benefit perception score" is calculated using the following formula. (8) (Overall cost-benefit score) =(2-C a) × (normalized time required) + C a × (Standardization costs) Here, C a Condition: 0 <C a A pre-set constant that satisfies <1 It may also be calculated using [this method]. In this case, the standardization time will contribute more significantly to the value of the "Overall Cost-Benefit Perception Score".
[0106] On the other hand, if the "cost-benefit perception information" includes the statement "costs are more likely to be perceived as cost-effective," then the "overall cost-benefit perception score" for this individual will be C a Condition: 1 <C a Assuming a predetermined constant that satisfies <2, the calculation can be performed using equation (8) above. In this case, the standardization cost will contribute more significantly to the value of the "overall cost-benefit score".
[0107] <Behavior promotion intervention means> Returning to the functional block diagram in Figure 1, the action promotion intervention unit 123 of this embodiment uses the priority order included in the action promotion plan for the target person obtained from the action promotion plan generation unit 122 to determine the disaster prevention action items that should be proposed to the target person, and provides the target person with "action proposal information" encouraging them to carry out the disaster prevention action items.
[0108] The acquired action promotion plan described above includes data that links (a) each disaster prevention action item, (b) information about the location where the disaster prevention action related to that action item will be performed (for example, information that the disaster prevention action will be performed at home or outside), and (c) the priority of the disaster prevention action item. Here, the action promotion intervention unit 123 can also determine the disaster prevention action items to be proposed to this target person, based on the location information of the target person (who is the user of terminal 2) acquired from the target positioning information storage unit 102, and using the location information of the disaster prevention action (as described in (b) above) included in the action promotion plan.
[0109] In the specific embodiment shown in Figure 9, the action-promoting intervention unit 123 transmits action suggestion information related to "checking the location of the nearest evacuation shelter on a map," which has a priority of 1, to the target person's terminal 2 (via the communication control unit 131 and the communication interface unit 101), for example, to the display of terminal 2 (which is equipped with a disaster prevention action promotion app), as an alert. Alternatively, such action suggestion information may be sent as a social media post or as an email.
[0110] Here, the action suggestion information, "Let's check the location of the nearest evacuation shelter on a map," which has a priority of 1, is preferably provided to the subject (the user of terminal 2) if the area (mesh) related to the subject's current location is "home," since the location where the disaster prevention action described in (b) above is performed is "home." Alternatively, if it is known from the subject's movement and stay activity log (determined based on GPS positioning information) that the subject usually stays at home until 9:00 a.m. on holidays, then it is also preferable to provide this action suggestion information by 9:00 a.m. on holidays (for example, at 8:30 a.m.).
[0111] Furthermore, if the subject is at "home" ("outside"), the action promotion intervention unit 123 may provide the subject with appropriate action suggestion information in order of priority for disaster prevention action items where the location for performing the disaster prevention action described in (b) above is "home" ("outside"). It is also possible to provide action suggestion information to the subject in order of priority, regardless of the subject's location. Moreover, when providing action suggestion information to the subject in order of priority, if the disaster prevention action item to which the action suggestion information to be provided pertains to a "one-time" action and that action suggestion information has already been provided, it is preferable to provide action suggestion information pertaining to the next highest priority (and which is either "continued" or "one-time" but has not yet been provided) disaster prevention action item.
[0112] Furthermore, in the embodiment shown in Figure 9, consider a case where, from the subject's activity log, it is known that, for example, this subject is busy with work on weekdays but has free time on weekends, and usually starts going out at 9 a.m. on Saturdays. In this case, the action promotion intervention unit 123 selects "Check the location of the nearest evacuation shelter on foot," which is the highest priority (priority 3) among the disaster prevention action items where the location of the disaster prevention action described in (b) above is "outside," and preferably provides the subject with action suggestion information related to this disaster prevention action item: "Let's check the location of the nearest evacuation shelter on foot," around 9 a.m. on Saturday, for example, by sending it to the subject's terminal 2. Here, the timing of providing this action suggestion information (around 9 a.m. on Saturday) is a suitable timing because it is expected that the subject will think, "I'll carry out the disaster prevention action while I'm out," that is, the perceived cost of disaster prevention action will decrease.
[0113] Figure 10 shows an example of behavioral suggestion information provided by the behavioral intervention unit 123.
[0114] The action suggestion information shown in Figure 10 is the action suggestion information for the above case, and is sent to the target person's terminal 2 at 9:00 AM on Saturday and displayed on the terminal 2's screen. Upon seeing this, the target person can, for example, walk to the nearest evacuation shelter, which is also displayed on the map.
[0115] Furthermore, in the embodiment shown in Figure 9, consider the case where the area (mesh) related to the current location of the subject (the user of terminal 2) is a "commercial facility." In this case, the action promotion intervention unit 123 selects "Implementing rolling stock of daily food items," which is the highest priority among the disaster prevention action items related to the purchase of supplies, etc., where the location to perform the disaster prevention action described in (b) above is "outside," and provides action suggestion information related to this disaster prevention action item: "Let's buy some of the food items you normally eat for rolling stock," to the subject who is currently in a commercial facility, for example, by sending it to the subject's terminal 2.
[0116] Figure 11 shows another example of behavioral suggestion information provided by the behavioral intervention unit 123.
[0117] The action suggestion information shown in Figure 11 is the action suggestion information for the above case, and is currently (15:32) transmitted to terminal 2 of the subject who is in the commercial facility and displayed on the screen of terminal 2. Upon seeing this, the subject can, for example, purchase retort curry for rolling stock at a supermarket located within the commercial facility.
[0118] Returning to the functional block diagram in Figure 1, the completion notification acquisition unit 131a included in the communication control unit 131 is capable of acquiring a completion notification from the target person (the user of terminal 2) who has been provided with the action suggestion information, indicating that they have carried out the disaster prevention action related to this action suggestion information. Here, this completion notification may be sent from terminal 2 to the completion notification acquisition unit 131a, for example, when the target person who actually carried out the disaster prevention action related to this action suggestion information inputs completion, for example, by tapping the completion icon on terminal 2 (which is equipped with a disaster prevention action promotion application).
[0119] Here, as one embodiment of feedback processing using this completion notification, (a) The risk perception paradox score determination unit 113 updates the action implementation score of the disaster prevention action item (related to disaster prevention action) related to the completion notification obtained for the subject. Specifically, if this action implementation score is 0 (not performed), it changes this action implementation score to 1, thereby updating the paradox score (0 or 1) of this disaster prevention action item, and finally determining the subject's risk perception paradox score P u Update, (b) The target risk score determination unit 114 determines at least the updated risk perception paradox score P u Based on this, the target risk score R for this subject u Update (recalculate), (c) The action promotion target determination unit 115 determines the target risk score R of the updated target uBased on this, it is also preferable to decide whether or not to provide the relevant action suggestion information to the subject again.
[0120] Furthermore, as another embodiment of the feedback processing using this completion notification, it is also preferable that the action promotion plan generation unit 122 raises the priority of disaster prevention action items other than the disaster prevention action items (related to disaster prevention actions) associated with the acquired completion notification for the target person.
[0121] Figure 12 is a table showing one example of feedback processing using completion notifications. In this example, completion notifications are sequentially received from the target person's terminal 2 for three disaster prevention action items with priority levels of 1, 2, and 3, respectively, out of the nine disaster prevention action items shown in the table in Figure 9.
[0122] In the embodiment shown in Figure 12, the risk perception paradox score determination unit 113 updates the paradox score for each disaster prevention action item based on the received completion notification. Specifically, it changes the paradox scores for the three disaster prevention action items related to the received completion notification from 1 to 0, thereby determining the subject's risk perception paradox score P u Update.
[0123] Next, the target risk score determination unit 114 calculates the updated risk perception paradox score P u Using this, the target risk score R of this subject is calculated. u The value is changed (updated) from 2.14 to 1.59. Subsequently, the action promotion target determination unit 115 uses the updated target risk score R of this individual. u Based on (=1.59), it is decided whether or not this subject should be designated as a subject to be provided with further action suggestion information. In this example, the threshold Th for determining the subject is set to 1.5, and therefore the subject risk score R u Those whose status has been updated to 1.59 are still designated as individuals who should be encouraged to take disaster prevention action (specified targets).
[0124] In the embodiment shown in Figure 12, the action promotion plan generation unit 122 changes the priority levels of the disaster prevention action items (related to disaster prevention actions) associated with the acquired completion notifications for the target person, specifically the six disaster prevention action items other than the three disaster prevention action items with priority levels 1, 2, and 3, from 4 to 9 to 1 to 6 (they are raised). After this, the action promotion intervention unit 123 can use the updated action promotion plan to provide action suggestion information that encourages disaster prevention actions more suitable for the target person, for example, action suggestion information related to disaster prevention action items whose priority level has been raised from 4 to 1.
[0125] The above describes in detail the various functional components that perform a series of processes in the disaster prevention action promotion device 1. In this embodiment, the administrator of the device 1 can use the keyboard, display, and user interface unit 105 (Figure 1), which is a touch panel display, to command the execution of these processes and to view and confirm the results of these processes, such as a target list in which the target risk score of each determined target person is linked, a generated action promotion plan for each target person, and a list of results for the action promotion intervention process and the feedback process (by completion notification).
[0126] As described in detail above, the present invention provides an apparatus, program, system, and method that enables encouraging disaster prevention actions to be taken by a target based on cost-benefit information (related to the risk perception paradox) concerning that target. Furthermore, the present invention provides an apparatus, program, system, and method that enables determining which target should be encouraged to take disaster prevention actions based on information related to the risk perception paradox concerning a candidate target.
[0127] For example, using one embodiment of the present invention, it becomes possible to propose disaster prevention actions to individuals who should be encouraged to take such actions, in accordance with the costs (burden) and benefits (sense of gaining profit or reward) they perceive in such actions. This makes it possible to bring about a sustainable change in disaster prevention behavior in these individuals. Also using one embodiment of the present invention, it becomes possible to select individuals who "want to take disaster prevention actions but find it difficult to actually do so" as targets for encouraging them to take such actions. This makes it possible to select individuals who have a high need for change in disaster prevention behavior from the perspective of the risk perception paradox as targets for encouraging them to take such actions.
[0128] Furthermore, according to one embodiment of the present invention, in order to maintain and develop the safe and healthy lives of each resident in a given area, it is possible to grasp the target risk score for each resident regarding various natural disasters, select residents who are judged to require disaster prevention action based on this target risk score, and provide appropriate disaster prevention and mitigation advice to the selected residents individually. In other words, according to the present invention, it is possible to contribute to Goal 3 of the United Nations-led Sustainable Development Goals (SDGs), "Ensure healthy lives and promote well-being for all at all ages," and Goal 11, "Make cities inclusive, safe, resilient and sustainable."
[0129] Various changes, modifications, and omissions to the scope of the technical concept and viewpoint of the present invention can be readily made by those skilled in the art with respect to the various embodiments of the present invention described above. The above description is merely illustrative and is not intended to limit the present invention in any way.
