Description

Blockchain-based corporate carbon emission management methods and systems

[0001] Various embodiments of the present disclosure relate to a method and system for managing carbon emissions of a blockchain-based enterprise, specifically, to a method and system for managing carbon emission rights in the form of tokens issued based on a blockchain.

[0002] In modern society, the importance of carbon emission management is increasing day by day. Carbon emissions primarily occur in sectors such as industrial activities, energy consumption, and transportation, accelerating global warming and climate change. Accordingly, the international community is introducing various agreements and policies to reduce greenhouse gas emissions. Notably, the Paris Agreement has set a goal to reduce carbon emissions globally and limit the rise in the average global temperature to below 1.5°C.

[0003] Carbon emission allowances are a system introduced as part of these efforts, representing the right for companies or nations to emit a certain amount of carbon. These allowances are tradable in the market, and companies must purchase additional allowances if their emissions exceed their allocated quotas. This incentivizes companies to focus on developing technologies to reduce carbon emissions and increasing operational efficiency. However, accurate measurement of carbon emissions and transparent data management are essential for the effective operation of this system.

[0004] The current carbon emission management system has several problems. First, it is difficult to ensure data reliability because carbon emissions are recorded manually. The manual method inherently carries the possibility of errors during the data entry process and entails inefficiency in the carbon emission verification process. Consequently, the precision and efficiency of carbon emission management are degraded. In particular, if carbon emission data is inaccurate, serious problems can arise regarding corporate carbon emission trading and regulatory compliance.

[0005] Second, there is a lack of a systematic approach to ensuring data integrity. Due to the insufficient reliability of data in current systems, it is difficult to verify the accuracy of energy consumption and carbon emission data. Consequently, there are instances where carbon emission data fails to gain the trust of regulatory bodies or stakeholders. In particular, there is an inadequate response to meeting detailed documentation requirements when applying methodologies at Tier 3 or higher. This prevents companies from effectively complying with required regulations and results in a deterioration of the quality of carbon emission reporting.

[0006] Third, there is a problem where the overall cost of the carbon emission management process increases due to the inefficiency of data management. Many companies must undergo separate external audits and reviews to verify carbon emission data, which increases the consumption of time and resources. Furthermore, the lack of centralized data management makes collaboration and data sharing among various stakeholders difficult, hindering the overall efficiency of carbon emission management.

[0007] The foregoing is provided as background technology for the purpose of aiding understanding of the present disclosure, and no claim or determination is made as to whether it can be applied as prior art related to the present disclosure.

[0034] According to various embodiments of the present disclosure, a transparent and reliable greenhouse gas reduction reporting system can be established by utilizing blockchain technology to prevent tampering with carbon emission data. Since the distributed ledger technology of blockchain shares records across all nodes when data is changed, the forgery and / or deletion of data is virtually impossible; thereby, trust between companies and regulatory bodies is enhanced, and the transparency of reduction data can be ensured.

[0035] According to various embodiments of the present disclosure, a dynamic cycle setting method can be introduced to actively induce carbon emission reduction activities by companies. Dynamic cycle setting can increase voluntary carbon emission reduction efforts by setting customized goals for carbon emission reduction considering each company's carbon emission characteristics and potential for reduction, and by providing incentives for excess carbon emission reductions. Furthermore, it can induce companies to participate in carbon emission reduction activities aimed at long-term sustainability, going beyond mere compliance with regulations.

[0036] According to various embodiments of the present disclosure, corporate motivation for participation can be strengthened by providing new revenue generation opportunities through a carbon emission trading system. Carbon emission trading can serve to alleviate the economic burden on companies resulting from excess carbon emissions, while simultaneously providing financial rewards to companies that achieve carbon emission reduction targets. Furthermore, various trading mechanisms utilizing carbon points can be used as a means to maximize the economic value of carbon emission reduction activities, and through such a system, companies can be made to recognize that carbon emission reduction activities can lead to revenue generation and enhanced competitiveness.

A smart contract may prevent tampering with the contents of said functions or rules by programming specific functions or rules and registering them on a blockchain, and may enable said functions or rules to be executed automatically when specific conditions are satisfied.

[0063] In the present disclosure, a "blockchain network" may represent a system or platform configured to record (or store) various transfer-related information occurring at one or more nodes in the form of a blockchain, or to verify the reliability of a block containing transfer-related information. Specifically, when the reliability of a block generated in the blockchain network is verified, the blockchain network may record the verified block in the form of a blockchain.

[0064] FIG. 1 is a schematic diagram illustrating an example of a configuration in which a plurality of systems and a blockchain are connected to communicate through a blockchain network according to one embodiment of the present disclosure. Referring to FIG. 1, a carbon emission monitoring system (110), a blockchain operating system (120), a carbon emission management system (130), and a blockchain (140) may be connected to or communicate with each other through a blockchain network (150). Each of the plurality of systems (110, 120, 130) may include a node of the blockchain network (150) or correspond to a node of the blockchain network (150). Additionally, a blockchain (140) may have a node including the blockchain (140) connected to the blockchain network (150) or communicate with the blockchain network (150).

[0065] The carbon emission monitoring system (110) can measure, calculate, and determine the carbon emissions of a company (10). In one embodiment, the carbon emission monitoring system (110) can obtain sensor data measured using a monitoring sensor installed in the company (10) from a company management system, and can determine the actual carbon emissions of the company (10) based on the sensor data and a pre-set coefficient.

[0066] Here, the company (10) may emit greenhouse gases in the process of operating the company / factory, etc. Accordingly, the monitoring sensor is a physical device or system that measures and monitors greenhouse gas emission data from the company (10) in real time, and may be a sensor approved by a specific regulatory body or certification body. For example, the monitoring sensor may include, but is not limited to, a gas analyzer (Continuous Emissions Monitoring System, CEMS) that measures exhaust gas directly emitted from a chimney, a flow sensor that measures the consumption of fuel or resources to indirectly calculate emissions, and an IoT-based smart sensor that continuously records fine greenhouse gas emissions generated in the process.

[0067] Additionally, the pre-set coefficient may be reference data or conversion factors necessary for calculating greenhouse gas emissions, for example, an emission factor, which is a numerical value used to convert the use of a specific fuel or resource into greenhouse gas emissions. However, the present disclosure is not limited thereto, and the pre-set coefficient may include various coefficients such as the Global Greenhouse Gas Accounting Standard (GHG Protocol), government regulatory data, and coefficients of greenhouse gas conversion equations.

[0068] The carbon emission monitoring system (110) can receive information related to carbon emissions of the company (10) from the company management system. For example, the carbon emission monitoring system (110) can collect sensor data related to greenhouse gas emissions collected through sensors installed in the company (10) via the company management system and transmit it via the blockchain network (150).

[0069] The enterprise management system can transmit information related to the carbon emissions of the enterprise (10) through a blockchain network (150). At this time, the enterprise management system can transmit information related to carbon emissions using an API gateway included in the enterprise management system. For example, the API gateway may include security credential information certificates required for secure communication with nodes. For example, the enterprise management system can transmit various requests to the API gateway through API calls. In this case, the API gateway calls a smart contract associated with the API call transmitted through the blockchain network (150), and the smart contract can be executed.

[0070] A blockchain operating system (120) can build / manage a blockchain (140) and a blockchain network (150). For example, the blockchain operating system (120) can manage whether to approve participation in the blockchain network (150). For example, the blockchain operating system (120) can manage whether to permit participation in a dedicated channel included in the blockchain network (150). For example, the blockchain operating system (120) can support the creation and / or operation of a dedicated channel included in the blockchain network (150) for each carbon emission monitoring system (110).

[0071] The carbon emission management system (130) may be operated by a carbon emission management agency (e.g., a public institution, an international organization, etc.). The carbon emission management agency may issue carbon emission rights and allocate them to companies (10), supervise carbon emission right trading, and / or establish policies related to carbon emissions. The carbon emission management system (130) may generate information related to carbon emission management and transmit information related to carbon emissions through a blockchain network (150). For example, the carbon emission management system (130) may transmit information regarding policies related to carbon emissions to the blockchain network (150). Additionally, the carbon emission management system (130) may monitor information related to carbon emissions. For example, the carbon emission management system (130) may receive information related to carbon emissions from a carbon emission monitoring system (110) and record carbon emissions by the carbon emission monitoring system (110) and / or companies (10) (or company management systems).

[0072] The blockchain (140) can store information related to carbon emissions. For example, the blockchain (140) can store sensor data of the company (10) and / or carbon emission data of the company (10) collected from the company management system. The carbon emission management system (130) can receive information related to carbon emissions stored in the blockchain (140) through the blockchain network (150).

[0073] The blockchain (140) may include a smart contract in which information related to carbon emissions can be read or updated. That is, the blockchain (140) may include information related to carbon emissions that can be read or updated by executing the smart contract. For example, sensor data of the company (10) and / or carbon emission data of the company (10) collected from the company management system may be updated according to a function or rule included in the smart contract.

[0074] In one embodiment, the blockchain (140) may include a private blockchain. Specifically, the blockchain (140) may only connect to nodes that are approved to participate in the blockchain network (150). Nodes approved to participate may query data stored in the blockchain (140) connected to the blockchain network (150). At this time, approval for participation in the blockchain network (150) may be managed by a blockchain operating system (120).

[0075] In FIG. 1, the blockchain (140) is shown as being directly connected to the blockchain network (150), but the present disclosure is not limited thereto. For example, one of a plurality of nodes associated with the blockchain (140) may be connected to the blockchain network (150) to perform operations such as recording, maintaining, storing, and deleting information related to carbon emissions on the blockchain (140).

[0076] Additionally, the carbon emission monitoring system (110) may communicate with a corporate management system that manages a single company (10) or manages multiple companies (10) in an integrated manner, but the present disclosure is not limited thereto. For example, the carbon emission monitoring system (110) may communicate with multiple corporate management systems that manage each of the multiple companies (10). Additionally, the blockchain network (150) may communicate with a single carbon emission monitoring system (110), a single blockchain operating system (120), and a single carbon emission management system (130), but the present disclosure is not limited thereto.

[0077] By using blockchain (140), various institutions and systems can access identical and integrity-guaranteed data. As a result, data consistency and reliability can be ensured. Specifically, carbon emission management agencies can issue carbon emission rights based on accurate data and improve reliability in the trading process of carbon emission rights.

[0078] Private blockchains can provide relatively higher processing speeds than public blockchains. For example, private blockchains can achieve processing speeds of over 1,000 TPS (Transactions Per Second), whereas public blockchains can exhibit processing speeds of 7 to 20 TPS. By utilizing such private blockchains, the real-time transmission and reception of information related to carbon emissions can be guaranteed. Furthermore, due to the high processing speed, integration with existing businesses can be facilitated.

[0079] Information related to carbon emissions is sensitive information, and its exposure needs to be prevented. By using a private blockchain, only authorized users can participate in the blockchain network (150), and only authorized users can access the data, thereby enhancing the security of the data.

[0080] FIG. 2 is a schematic diagram showing a configuration in which an information processing system (230) and a plurality of user terminals (210_1, 210_2, 210_3) are connected to enable communication according to one embodiment of the present disclosure. Referring to FIG. 2, a plurality of user terminals (210_1, 210_2, 210_3) can be connected to an information processing system (230) capable of providing a blockchain-based enterprise carbon emission management service through a network (220). Here, the information processing system (230) may correspond to or be included in each of the nodes associated with the carbon emission monitoring system (110), enterprise (10) and enterprise management system, blockchain operating system (120), carbon emission management system (130), and blockchain (140) described with reference to FIG. 1. Additionally or alternatively, a plurality of user terminals (210_1, 210_2, 210_3) may correspond to or be included in each of the nodes associated with the carbon emission monitoring system (110), enterprise (10) and enterprise management system, blockchain operating system (120), carbon emission management system (130) and blockchain (140) described with reference to FIG. 1.

Similarly, the information processing system (230) may include a memory (332), a processor (334), a communication module (336), and an input / output interface (338). The user terminal (210) and the information processing system (230) may be configured to communicate information and / or data through the network (220) using their respective communication modules (316, 336). Additionally, the input / output device (320) may be configured to input information and / or data to the user terminal (210) or output information and / or data generated from the user terminal (210) through the input / output interface (318).

[0087] The memory (312, 332) may include any non-transient computer-readable recording medium. According to one embodiment, the memory (312, 332) may include a permanent mass storage device such as ROM (read-only memory), a disk drive, an SSD (solid-state drive), or a flash memory. As another example, a permanent mass storage device such as ROM, an SSD, a flash memory, or a disk drive may be included in the user terminal (210) or the information processing system (230) as a separate permanent storage device distinct from the memory. Additionally, the memory (312, 332) may store an operating system and at least one program code (e.g., code for a blockchain-based enterprise carbon emission management service application installed and running on the user terminal (210)).

[0088] These software components may be loaded from a computer-readable recording medium separate from memory (312, 332). This separate computer-readable recording medium may include a recording medium that can be directly connected to the user terminal (210) and the information processing system (230), for example, a computer-readable recording medium such as a floppy drive, disk, tape, DVD / CD-ROM drive, or memory card. As another example, the software components may be loaded into memory (312, 332) via a communication module rather than a computer-readable recording medium. For example, at least one program may be loaded into memory (312, 332) based on a computer program installed by files provided through a network (220) by developers or a file distribution system that distributes installation files for the application.

[0089] The processor (314, 334) may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations. Instructions may be provided to the processor (314, 334) by memory (312, 332) or a communication module (316, 336). For example, the processor (314, 334) may be configured to execute instructions received according to program code stored in a recording device such as memory (312, 332).

[0090] The communication module (316, 336) may provide a configuration or function for the user terminal (210) and the information processing system (230) to communicate with each other via the network (220), and may provide a configuration or function for the user terminal (210) and / or the information processing system (230) to communicate with another user terminal or another system (e.g., a separate cloud system). For example, a request or data (e.g., a request for carbon emission management of a blockchain-based enterprise) generated by the processor (314) of the user terminal (210) according to program code stored in a recording device such as memory (312) may be transmitted to the information processing system (230) via the network (220) under the control of the communication module (316). Conversely, a control signal or command provided under the control of the processor (334) of the information processing system (230) can be received by the user terminal (210) through the communication module (336) and the network (220) via the communication module (316) of the user terminal (210).

[0091] The input / output interface (318) may be a means for interfacing with an input / output device (320). As an example, the input device may include a device such as a camera including an audio sensor and / or an image sensor, a keyboard, a microphone, or a mouse, and the output device may include a device such as a display, a speaker, or a haptic feedback device. As another example, the input / output interface (318) may be a means for interfacing with a device in which the configuration or function for performing input and output is integrated into one, such as a touchscreen. For example, when the processor (314) of the user terminal (210) processes instructions of a computer program loaded in memory (312), a service screen configured using information and / or data provided by an information processing system (230) or another user terminal may be displayed on a display through the input / output interface (318). In FIG. 3, the input / output device (320) is depicted as not being included in the user terminal (210), but is not limited thereto and may be configured as a single device with the user terminal (210). Additionally, the input / output interface (338) of the information processing system (230) may be a means for interfacing with a device (not shown) for input or output that is connected to the information processing system (230) or that the information processing system (230) may include. In FIG. 3, the input / output interface (318, 338) is shown as an element configured separately from the processor (314, 334), but is not limited thereto, and the input / output interface (318, 338) may be configured to be included in the processor (314, 334).

[0092] The user terminal (210) and the information processing system (230) may include more components than those of FIG. 3. However, it is not necessary to clearly illustrate most of the prior art components. According to one embodiment, the user terminal (210) may be implemented to include at least some of the input / output devices (320) described above. Additionally, the user terminal (210) may further include other components such as a transceiver, a GPS (Global Positioning System) module, a camera, various sensors, a database, etc. For example, if the user terminal (210) is a smartphone, it may include components that are generally included in a smartphone, and may be implemented to further include various components such as an accelerometer, a gyroscope, an image sensor, a proximity sensor, a touch sensor, an ambient light sensor, a camera module, various physical buttons, buttons using a touch panel, input / output ports, and a vibrator for vibration.

[0093] While a program or application for carbon emission management services for a blockchain-based enterprise is in operation, the processor (314) can receive text, images, video, voice and / or actions, etc., that are input or selected through an input device such as a touch screen, keyboard, audio sensor and / or image sensor, camera, microphone, etc., connected to an input / output interface (318), and can store the received text, images, video, voice and / or actions, etc. in memory (312) or provide them to an information processing system (230) through a communication module (316) and a network (220).

[0094] The processor (314) of the user terminal (210) may be configured to manage, process, and / or store information and / or data received from an input / output device (320), another user terminal, an information processing system (230), and / or a plurality of external systems. The information and / or data processed by the processor (314) may be provided to the information processing system (230) through a communication module (316) and a network (220). The processor (314) of the user terminal (210) may transmit information and / or data to the input / output device (320) through an input / output interface (318) to output it. For example, the processor (314) may display the received information and / or data on the screen of the user terminal (210).

[0095] The processor (334) of the information processing system (230) may be configured to manage, process, and / or store information and / or data received from a plurality of user terminals (210) and / or a plurality of external systems. The information and / or data processed by the processor (334) may be provided to the user terminals (210) through a communication module (336) and a network (220).

[0096] FIG. 4 is a flowchart illustrating a method for managing carbon emissions of a blockchain-based enterprise according to one embodiment of the present disclosure. The method (400) may be performed by at least one processor of a user terminal and / or information processing system.

[0097] Referring to FIG. 4, in step S410 of the method (400), the processor may issue carbon emission tokens corresponding to carbon emission rights allocated to the target company. In one embodiment, when carbon emission rights for a predetermined amount of carbon emissions are allocated to the target company, the processor may issue a number of carbon emission tokens corresponding to the predetermined amount of carbon emissions through a smart contract on a blockchain network. Additionally, the processor may transfer the carbon emission tokens issued in correspondence with the target company's carbon emission rights to the target company's digital wallet.

[0098] Here, carbon emission tokens may include Non-fungible Tokens (NFTs). A Non-fungible Token (NFT) refers to a token that utilizes blockchain technology to grant uniqueness to digital assets and authenticate ownership. While existing fungible tokens allow for the mutual exchange of multiple units of the same value, NFTs are non-exchangeable because each token possesses unique characteristics. This characteristic enables NFTs to be utilized in various applications where it is necessary to prove ownership of digital assets or to assign scarcity. NFTs contain unique identification information and metadata, which transparently record the authenticity and ownership of tokenized assets on the blockchain network. Ethereum is a representative blockchain platform, and standards such as ERC-721 and ERC-1155 are frequently used for NFT implementation. These standards guarantee the interoperability of NFTs and allow the same NFT to be used across various decentralized applications (DApps).

[0099] Subsequently, in step S420 of the method (400), the processor can determine the carbon emissions of the target company at predetermined intervals. In one embodiment, the processor can determine the actual carbon emissions of the target company at predetermined intervals based on sensor data measured through a monitoring sensor installed in the company and a preset coefficient (e.g., emission coefficient). Here, the predetermined interval is a period set by the target company and / or the carbon emission management agency and can be dynamically adjusted.

[0100] Subsequently, in step S430 of the method (400), the processor may burn carbon emission tokens stored in the target company's digital wallet according to (or based on) the target company's carbon emissions. In one embodiment, when the actual carbon emissions of the target company are determined at a predetermined period, the processor may burn a number of carbon emission tokens corresponding to the actual carbon emissions of the target company among a plurality of carbon emission tokens stored in the target company's digital wallet.

[0101] In one embodiment, the processor may generate a report at a predetermined periodicity containing information regarding the actual carbon emissions of the target company, the number of carbon emission tokens burned according to the actual carbon emissions, the remaining carbon emission tokens stored in the target company's digital wallet, and the remaining carbon emissions corresponding to the remaining carbon emission tokens.

[0102] FIG. 5 is a flowchart illustrating a method for determining whether a greenhouse gas reduction target has been achieved according to one embodiment of the present disclosure. The method (500) may be performed by at least one processor of a user terminal and / or information processing system.

[0103] Referring to FIG. 5, in step S510 of the method (500), the processor may determine the remaining carbon emissions of the target company based on the remaining carbon emission tokens stored in the target company's digital wallet for the purpose of determining whether the target company has achieved its goal regarding greenhouse gas reduction. For example, the remaining carbon emissions of the target company may be determined by multiplying the remaining carbon emission tokens stored in the target company's digital wallet with the carbon emissions corresponding to each carbon emission token.

[0104] Subsequently, in step S520 of the method (500), the processor may compare the remaining carbon emissions determined based on the remaining carbon emission tokens stored in the target company's digital wallet with the greenhouse gas target reduction amount set for the target company. Here, the greenhouse gas target reduction amount set for the target company may be a target value set during the process of allocating carbon emission rights to the target company, but is not limited thereto.

[0105] At this time, in step S530 of the method (500), the processor may determine that the target company has achieved the greenhouse gas reduction target if the remaining carbon emissions of the target company are greater than or equal to the greenhouse gas target reduction amount. On the other hand, in step S540 of the method (500), the processor may determine that the target company has not achieved the greenhouse gas reduction target if the remaining carbon emissions of the target company are less than the greenhouse gas target reduction amount.

[0106] In one embodiment, the processor compares the target company's greenhouse gas target reduction amount with the target company's remaining carbon emissions, and if the target company has reduced carbon emissions by a first size, the carbon emissions of the first size can be converted into carbon points and paid to the target company. At this time, the processor can pay additional carbon points to the target company based on at least one of the size of the target company's excess greenhouse gas reduction amount and the number of times the target company has exceeded greenhouse gas reduction (number of times during a specified period and / or number of consecutive excess reductions, etc.). Additionally, the processor can determine a carbon point conversion ratio for the excess reduction amount based on at least one of the size of the target company's excess greenhouse gas reduction amount and the number of times the target company has exceeded greenhouse gas reduction (number of times during a specified period and / or number of consecutive excess reductions, etc.), and can convert carbon emissions of the first size into carbon points and pay them to the target company based on the carbon point conversion ratio.

[0107] In one embodiment, the processor compares the target company's greenhouse gas target reduction amount with the target company's remaining carbon emissions, and if the target company has emitted carbon emissions in excess of a second size, it can deduct carbon points from the carbon points held by the target company that correspond to the second size of carbon emissions.

[0108] In one embodiment, the processor compares the target company's greenhouse gas target reduction amount with the target company's remaining carbon emissions, and if the target company has reduced carbon emissions by a predetermined amount, the processor may mediate the transaction of carbon emission tokens between the target company and a token purchasing company that wishes to purchase carbon emission tokens. Here, the target company and the token purchasing company wishing to purchase carbon emission tokens may be a company that requested to purchase the target company's carbon emission tokens, or a company that has exceeded carbon emissions by an amount corresponding to the carbon emissions held by the target company.

[0109] In one embodiment, the processor compares the target company's greenhouse gas target reduction amount with the target company's remaining carbon emissions, and if the target company has emitted carbon emissions in excess of a predetermined amount, the processor may mediate the transaction of carbon emission tokens between the target company and a token selling company that intends to sell carbon emission tokens. Here, the target company and the token selling company that intends to sell carbon emission tokens may be companies that have registered their own carbon emission tokens for sale, or companies that have reduced their carbon emissions in excess by an amount equal to the carbon emissions in excess emitted by the target company.

[0110] FIG. 6 is a flowchart illustrating a carbon emission token trading method according to one embodiment of the present disclosure. The method (600) may be performed by at least one processor of a user terminal and / or information processing system.

[0111] Referring to FIG. 6, in step S610 of the method (600), the processor may obtain a transaction request for carbon emission tokens from a target company. Here, the transaction request for carbon emission tokens obtained from the target company may be a purchase request for carbon emission tokens sold by a specific token selling company or a sale request for carbon emission tokens to a specific token buying company, but is not limited thereto.

[0112] Subsequently, in step S620 of the method (600), the processor may mediate the transaction of carbon emission tokens through a smart contract on a blockchain network in accordance with (or in response to) a transaction request obtained from the target company. For example, if the processor obtains a purchase request from the target company for carbon emission tokens sold by a specific token selling company, it may transfer carbon emission tokens equal to the cost paid by the target company from the specific token selling company's digital wallet to the target company's digital wallet through a smart contract. As another example, if the processor obtains a sale request from the target company for carbon emission tokens to a specific token buying company, it may transfer carbon emission tokens equal to the cost paid by the specific token buying company from the target company's digital wallet to the specific token buying company's digital wallet through a smart contract. Here, the cost paid for the transaction of carbon emission tokens may be carbon points, but is not limited thereto.

[0113] The method described above may be provided as a computer program stored on a computer-readable recording medium for execution on a computer. The medium may continuously store a program executable by a computer, or temporarily store it for execution or download. Additionally, the medium may be various recording or storage means in the form of a single or multiple hardware components combined, and may not be limited to a medium directly connected to a computer system but may exist distributed over a network.
