[0008] The following describes in detail an embodiment of the method for installing a radiation shielding room according to the present invention, based on the drawings. However, this embodiment does not limit the present invention.

[0009] Figure 1 is a schematic diagram showing an example of the installation of a shielding room according to one embodiment. The shielding room 1 (radiation shielding room) is used, for example, in a medical facility such as a hospital. The shielding room 1 has the function of shielding from radiation. Radiation includes, for example, X-rays, gamma rays, and neutrons. Radiation equipment is placed inside the shielding room 1. The shielding room 1 is used as a room for using radiation equipment. Radiation equipment includes, for example, X-ray machines, CT (Computed Tomography) scanners, barium examination machines, and linear accelerators, proton beam therapy machines, and heavy ion beam therapy machines. The type of radiation equipment is not particularly limited.

[0010] Shielding room 1 is installed inside a room in medical facility S. Shielding room 1 is installed, for example, inside the X-ray room of medical facility S. "Installed" includes being placed on the floor of the room. Furthermore, "installed" includes being placed on the floor of the room and fixed to the floor, and being fixed to the floor and fixed to the wall of the room.

[0011] The method for installing the shielding room 1 according to this embodiment is a method for installing the shielding room 1 inside a room. In order to use a room in a medical facility S as a shielding room, it is conceivable to transport radiation shielding material containing lead or the like to the medical facility S and construct the shielding room using that shielding material. However, shielding material containing lead or the like is heavy and large. For this reason, conventional methods for installing shielding rooms have resulted in high construction costs, such as increased labor costs and long construction periods. In contrast, it is conceivable to construct a shielding room using lightweight and small shielding material, but further reduction of construction costs was required.

[0012] The installation method for the shielding room 1 according to this embodiment has a unique configuration described below in order to solve the above-mentioned problems. The installation method for the shielding room 1 will be described in detail below.

[0013] [First Embodiment] Figure 2 is a flowchart illustrating the installation method of the shielding room 1 according to the first embodiment. The first embodiment can be applied when the manufactured shielding room 1 can be transported into the room. For example, when installing the shielding room 1 in a newly constructed medical facility S, it is easy to secure a route for transporting the shielding room 1 into the room. In such cases, it is considered possible to transport the manufactured shielding room 1 into the room. However, the shielding room 1 may have to be transported by elevator for reasons such as the room in which the shielding room 1 is to be installed being on the second floor or higher. In this case, even if a route for transporting the shielding room 1 into the room can be secured, it may not be possible to transport the shielding room 1 into the elevator. In this case, it can be said that the manufactured shielding room 1 cannot be transported into the room. The installation method of the shielding room 1 according to this embodiment comprises a manufacturing process, a transport process, an installation process, and an adjustment process.

[0014] In the manufacturing process, the shielding chamber 1 is manufactured (step S1). In step S1, for example, the shielding chamber 1 is manufactured outside the medical facility S. The configuration of the shielding chamber 1 manufactured in step S1 will be described.

[0015] FIG. 3 is a schematic side view of the shielding chamber shown in FIG. 1. FIG. 4 is a schematic plan view showing the floor portion shown in FIG. 3. FIG. 5 is a schematic view showing the vicinity of the wheels of the shielding chamber shown in FIG. 3. As shown in FIG. 3, the shielding chamber 1 includes a floor portion 2, a wall portion 3, and a ceiling portion 4.

[0016] The floor portion 2 constitutes the bottom of the shielding chamber 1. The floor portion 2 is in contact with the indoor floor. As shown in FIG. 4, the floor portion 2 includes a floor board 21, a plurality of wheels 22, and a plurality of adjustment portions 23.

[0017] The floor board 21 constitutes the floor of the shielding chamber 1. The floor board 21 is square in plan view. The floor board 21 extends in a first direction D1 that intersects (for example, is orthogonal to) the vertical direction and a second direction D2 that intersects both the vertical direction and the first direction D1. The shape of the floor board 21 is not particularly limited, and may be, for example, circular, polygonal, or a shape other than these shapes.

[0018] The plurality of wheels 22 are provided for moving the shielding chamber 1. The wheels 22 are swivel casters (swivel wheels). However, the type of the wheels 22 is not particularly limited, and fixed casters (fixed wheels) may also be used. In the present embodiment, the shielding chamber 1 includes four wheels 22. Each of the four wheels 22 is provided at a corner of the floor board 21.

[0019] As shown in FIG. 5, the wheel 22 includes a threaded portion 22a. The threaded portion 22a is a male screw portion for screwing into a threaded portion 52 described later. The threaded portion 22a constitutes the upper part of the wheel 22.

[0020] The wheel 22 is provided in a wheel installation portion 5. The floor board 21 includes the same number of wheel installation portions 5 as the wheels 22. The wheel installation portion 5 is for detachably installing the wheel 22. In the present embodiment, the wheel installation portion 5 includes a concave portion 51 and a threaded portion 52.

[0021] The recess 51 is recessed from the lower surface of the floor plate 21. The cross-section of the recess 51 is circular. However, the cross-sectional shape of the recess 51 is not particularly limited. The threaded portion 52 is provided in the recess 51. The threaded portion 52 is provided at the bottom of the recess 51. The threaded portion 52 is a female threaded portion for screwing the threaded portion 22a.

[0022] In this embodiment, the wheel installation portion 5 includes the recess 51. However, the configuration of the wheel installation portion 5 can be changed as appropriate. For example, the wheel installation portion 5 may include a through hole penetrating the floor plate 21 instead of the recess 51. In this case, the threaded portion 52 may be fitted into the through hole.

[0023] By screwing the threaded portion 22a into the threaded portion 52 and rotating the threaded portion 22a, the wheel 22 can move forward and backward in one direction (for example, the vertical direction). The wheel 22 can move forward and backward with respect to the floor plate 21. That is, the protruding length of the wheel 22 from the floor plate 21 can be adjusted.

[0024] The adjustment portion 23 is for performing horizontal adjustment of the floor portion 2. The adjustment portion 23 is an adjustment screw that can move forward and backward in one direction (for example, the vertical direction). The adjustment screw of the adjustment portion 23 includes a threaded portion 23a. The threaded portion 23a is a male threaded portion for screwing into the threaded portion 62 described later. The threaded portion 23a constitutes the upper part of the adjustment portion 23.

[0025] The adjustment portion 23 is provided in the adjustment installation portion 6 (installation portion). The floor plate 21 includes more adjustment installation portions 6 than the adjustment portion 23. The adjustment installation portion 6 is for detachably installing the adjustment portion 23. In this embodiment, the adjustment installation portion 6 includes a recess 61 and a threaded portion 62.

[0026] The recess 61 is recessed from the lower surface of the floor plate 21. The cross-section of the recess 61 is circular. However, the cross-sectional shape of the recess 61 is not particularly limited. The threaded portion 62 is provided at the bottom of the recess 61. The threaded portion 62 is a female threaded portion for screwing the threaded portion 23a.

[0027] In this embodiment, the adjustment mounting section 6 includes a recess 61. However, the configuration of the adjustment mounting section 6 can be changed as appropriate. For example, the adjustment mounting section 6 may include a through hole that penetrates the floor plate 21 instead of the recess 61. In this case, the screw portion 62 may be fitted into the through hole.

[0028] By screwing the threaded portion 23a into the threaded portion 62 and rotating the threaded portion 23a, the adjustment portion 23 can move back and forth in one direction. The adjustment portion 23 can move back and forth relative to the floor plate 21. In other words, the adjustment portion 23 can adjust the height of its protrusion from the floor plate 21.

[0029] The maximum protrusion height of the adjustment unit 23 is greater than the minimum protrusion height of the wheel 22. The maximum protrusion height of the adjustment unit 23 may also be greater than, for example, the maximum protrusion height of the wheel 22. As a result, when the shielding room 1 is installed on the floor of a room, the adjustment unit 23 can support the shielding room 1. In this case, for example, the wheel 22 may be separated from the floor of the room.

[0030] Next, the positions of the adjustment unit 23 and the adjustment installation unit 6 will be explained in detail using Figure 4.

[0031] As shown in Figure 4, the floor plate 21 includes a plurality of adjustment mounting sections 6. In this embodiment, the number of adjustment mounting sections 6 is greater than the number of adjustment sections 23 and greater than the number of wheels 22. Each of the plurality of adjustment mounting sections 6 corresponds to each of the plurality of wheels 22. Each of the plurality of adjustment mounting sections 6 is provided near one of the wheels 22.

[0032] Each wheel 22 corresponds to one of several (two in this embodiment) adjustment mounting sections 6. In this embodiment, since the floor section 2 includes four wheels 22, the floor plate 21 includes eight adjustment mounting sections 6. For the sake of explanation, of the two adjustment mounting sections 6 corresponding to one wheel 22, one adjustment mounting section 6 will be referred to as adjustment mounting section 6A, and the other adjustment mounting section 6, which is different from the first adjustment mounting section 6, will be referred to as adjustment mounting section 6B. In this embodiment, each of the multiple adjustment sections 23 is provided in adjustment mounting section 6A, but not in adjustment mounting section 6B. Furthermore, a straight line extending in the first direction D1 that passes through the center of the floor plate 21 in the second direction D2 is defined as straight line L1, and a straight line extending in the second direction D2 that passes through the center of the floor plate 21 in the first direction D1 is defined as straight line L2.

[0033] The distance from the adjustment mounting section 6A to the straight line L1 is shorter than the distance from the wheel 22 to the straight line L1. The distance from the adjustment mounting section 6A to the straight line L1 is shorter than the distance from the adjustment mounting section 6B to the straight line L1. The distance from the adjustment mounting section 6A to the wheel 22 is shorter than the distance from the adjustment mounting section 6A to the straight line L1. The distance from the adjustment mounting section 6A to the wheel 22 is shorter than the distance from the adjustment mounting section 6A to the straight line L2.

[0034] The distance from the adjustment mounting section 6B to the straight line L2 is shorter than the distance from the wheel 22 to the straight line L2. The distance from the adjustment mounting section 6B to the straight line L2 is shorter than the distance from the adjustment mounting section 6A to the straight line L2. The distance from the adjustment mounting section 6B to the wheel 22 is shorter than the distance from the adjustment mounting section 6B to the straight line L2. The distance from the adjustment mounting section 6B to the wheel 22 is shorter than the distance from the adjustment mounting section 6B to the straight line L1.

[0035] The floor section 2 includes the same number of adjustment sections 23 as the number of wheels 22. Each of the multiple adjustment sections 23 is provided on one of the multiple adjustment mounting sections 6 described above. As a result, each of the multiple adjustment sections 23 corresponds to each of the multiple wheels 22. Thus, each of the multiple adjustment sections 23 is provided near one of the wheels 22.

[0036] In this embodiment, the distance from one adjustment unit 23 to the straight line L1 is shorter than the distance from the wheel 22 corresponding to the adjustment unit 23 to the straight line L1. In the example of Figure 4, the adjustment unit 23 is provided in the adjustment installation unit 6A, but the adjustment unit 23 may also be provided in the adjustment installation unit 6B. In this case, the distance from one adjustment unit 23 to the straight line L2 will be shorter than the distance from the wheel 22 corresponding to the adjustment unit 23 to the straight line L2.

[0037] The wall portion 3 shown in Figure 3 constitutes the wall of the shielded room 1. The wall portion 3 protrudes from the periphery of the floor portion 2. Specifically, the wall portion 3 protrudes upward from the upper surface of the floor plate 21. In this embodiment, the floor plate 21 is rectangular in plan view, and the wall portion 3 includes side wall portions that protrude from each side of the floor plate 21.

[0038] The wall section 3 includes, for example, a shielding material containing lead. However, the shielding material may also include building materials that do not contain lead (e.g., lead-free board). The type of shielding material is not particularly limited as long as it can shield radiation. The shielding material may include cement or a material that can absorb radiation (e.g., boron). The wall section 3 includes a door 3a for entering and exiting the shielding room 1.

[0039] The ceiling section 4 constitutes the ceiling of the shielding room 1. The material of the ceiling section 4 is the same as the material of the wall section 3. However, the type of ceiling section 4 is not particularly limited, as long as it can shield against radiation.

[0040] In the manufacturing process, the shielding room 1 is manufactured with the medical equipment housed inside. Specifically, in step S1, the floor section 2 is first formed. Then, the medical equipment is placed on the floor section 2. Next, the walls 3 and ceiling section 4 are formed on the floor board 21 using cement or the like. Electrical systems for using the medical equipment (including, for example, power supply, wiring, and switches) are also installed. As a result, the manufacturing of the shielding room 1 is completed. The medical equipment is housed in the shielding room 1, which has radiation shielding properties.

[0041] In the delivery process, after the manufacturing process, the shielding room 1 manufactured in step S1 is delivered into the room (step S2). In step S2, the shielding room 1 containing the medical equipment is delivered. Specifically, the shielding room 1 is delivered into the room via the traffic flow into the room of the medical facility S. At this time, since the floor section 2 includes multiple wheels 22, the shielding room 1 can be easily moved.

[0042] In the installation process, the shielding chamber 1 is installed inside the room (step S3). In step S3, the shielding chamber 1 that has been brought into the room is installed. Specifically, the shielding chamber 1 is positioned at a desired location inside the room. Then, by rotating the adjustment unit 23 and the wheels 22, the protruding height of the adjustment unit 23 is made greater than the protruding height of the wheels 22. As a result, the wheels 22 are separated from the floor of the room, and the tip of the adjustment unit 23 touches the floor. In addition, the shielding chamber 1 is supported by multiple adjustment units 23.

[0043] In the adjustment process, the floor section 2 is leveled using multiple adjustment units 23 (step S4). In step S4, for example, a spirit level is placed on the floor plate 21. Then, the protruding height of the adjustment unit 23 is adjusted based on the inclination indicated by the spirit level. After these processes, the installation method of the shielding room 1 is completed.

[0044] After performing step S3 or step S4, at least one of the wall section 3 and the ceiling section 4 may be fixed to the wall or ceiling of the room. This allows the shielded room 1 to be more firmly fixed to the room.

[0045] When building materials for a shielding room are transported to the construction site and the shielding room is constructed, labor costs for construction increase, and the construction period may be extended, potentially resulting in high construction costs. Shielding materials containing lead, etc., are heavy and large. Working with heavy and large building materials at the construction site requires significant labor costs and a long construction period. In particular, tight construction deadlines may be a concern. In contrast, in this embodiment, the shielding room 1 is manufactured outside the construction site and then installed. Therefore, labor costs required for constructing the shielding room 1 can be reduced, and the construction period can be shortened. Consequently, construction costs can be reduced.

[0046] Furthermore, according to this embodiment, the shielding room 1 can be mass-produced before receiving an order for its installation. In this case, construction costs can be further reduced. In particular, for small clinics, reducing construction costs lowers the barriers to opening up.

[0047] In the construction method of the shielding room 1 according to this embodiment, instead of transporting building materials to the construction site and using the transported materials to construct the shielding room 1, the shielding room 1 is manufactured and then installed inside the room. Thus, the method of installing the shielding room 1 involves a completely different technical concept from conventional methods of installing shielding rooms.

[0048] In this embodiment, the floor section 2 includes a plurality of adjustment sections 23 for adjusting the horizontal level of the floor section 2. This allows the floor section 2 to be adjusted horizontally by the adjustment sections 23 even if it becomes tilted relative to the horizontal plane after the shielding room 1 is brought into the room and during the process of using the shielding room 1. Furthermore, since the adjustment sections 23 are adjustment screws that can move back and forth in one direction (for example, vertically), the horizontal level of the floor section 2 can be easily adjusted.

[0049] Medical devices that emit radiation are often heavy and large, making it difficult to bring them into a shielding room after its construction. Therefore, various methods of bringing them in have been employed. For example, firstly, the medical devices are brought in before the shielding room is constructed. Secondly, the room is divided into an operation room for operating the medical devices and a shielding room, with the medical devices being brought into the shielding room from the operation room. Thirdly, the medical devices are disassembled, their components are brought into the room, and the devices are assembled there. All of these methods involved significant costs, including substantial labor costs and long working periods.

[0050] In contrast, in this embodiment, the shielding chamber 1 is manufactured in the manufacturing process with the medical device housed inside it. In the delivery process, the shielding chamber 1 containing the medical device is delivered. As a result, the medical device can be delivered into the room together with the shielding chamber 1, thus reducing the cost of delivering the medical device into the room compared to conventional methods.

[0051] Furthermore, since the medical equipment is placed inside shielding room 1 outside the construction site before it is brought inside, the radiation shielding effect of shielding room 1 can be confirmed in advance.

[0052] [Second Embodiment] Next, the installation method of the shielding room 1A according to the second embodiment will be described. The second embodiment can be applied when it is not possible to transport the manufactured shielding room 1A into the room. For example, when installing the shielding room 1A in an already constructed medical facility S, it is difficult to secure a route for transporting the shielding room 1A into the room. Also, when it is necessary to transport the shielding room 1A by elevator, it may not be possible to transport the shielding room 1A into the elevator. In particular, when installing the shielding room 1A in a clinic operating as a tenant in a building, it may be necessary to transport the shielding room 1A by elevator. In these cases, it is not possible to transport the manufactured shielding room 1A into the room.

[0053] First, before explaining the installation method of shielding room 1A, the configuration of shielding room 1A will be explained using Figures 6 and 7. Figure 6 is a schematic exploded view showing an example of a divided room. Figure 7 is a schematic plan view showing the floor according to the second embodiment. Shielding room 1A has a configuration similar to that of shielding room 1. Below, the differences from shielding room 1 will be mainly explained, and redundant explanations will be omitted as appropriate.

[0054] As shown in Figure 6, the shielding room 1A is composed of a plurality of divided rooms 10. The plurality of divided rooms 10 are divisions of the shielding room 1A in a plan view. In this embodiment, each of the plurality of divided rooms 10 is one of four divisions of the shielding room 1A. Note that in Figure 6, the illustration of some of the four divided rooms 10 is omitted. Each of the plurality of divided rooms 10 includes a divided floor section 12, a divided wall section 13, and a divided ceiling section 14.

[0055] As shown in Figure 7, the divided floor section 12 is a division of the floor section 2 of the shielded room 1A in a plan view. The configuration of the divided floor section 12 is the same as the configuration of the floor section 2 of the shielded room 1. That is, each of the multiple divided floor sections 12 includes a floor plate 21, multiple wheels 22, and multiple adjustment parts 23. Since each of the multiple divided floor sections 12 includes multiple wheels 22, the divided floor sections 12 can be made self-supporting and movable using the wheels 22.

[0056] Figure 8 is a flowchart showing the method for installing a shielding room according to the second embodiment. The method for installing the shielding room 1A comprises a divided room manufacturing process, a delivery process, a manufacturing process, an installation process, and an adjustment process.

[0057] In the partitioned room manufacturing process, multiple partitioned rooms 10 are manufactured before the installation process (step S11). In step S11, partitioned rooms 10 of a size that can be transported into the room of the medical facility S are manufactured. In step S11, first, multiple partitioned floor sections 12 are formed. Then, for all partitioned floor sections 12, partitioned wall sections 13 and partitioned ceiling sections 14 are formed on the floorboards 21 of the partitioned floor sections 12 using cement or the like. Electrical systems for using medical equipment are also installed. As a result, the manufacturing of multiple partitioned rooms 10 is completed.

[0058] In this embodiment, the multiple divided chambers 10 are manufactured separately. However, the multiple divided chambers 10 may also be manufactured by dividing (e.g., cutting) the shielding chamber 1A after it has been manufactured. The method for manufacturing the divided chambers 10 is not particularly limited.

[0059] In the loading process, the multiple divided chambers 10 manufactured in step S11 are loaded into the room (step S12). In step S12, each of the multiple divided chambers 10 is loaded into the room using the multiple wheels 22 included in the divided floor section 12.

[0060] In the manufacturing process, the shielding room 1A is manufactured inside the room by assembling the multiple divided rooms 10 that were brought into the room during the loading process (step S13). In step S13, the shielding room 1A is manufactured by joining the multiple divided rooms 10 together. Specifically, the multiple divided rooms 10 are brought into contact with each other, and the contact parts are joined using a bonding member such as cement. Furthermore, the contact parts of two divided wall sections 13 may be joined using a bonding member such as a staple. This makes the joint between the multiple divided rooms 10 even stronger.

[0061] In the installation process, the shielding chamber 1A is installed inside the room (step S14). In step S14, the manufactured shielding chamber 1A is installed inside the room. Specifically, the shielding chamber 1A is positioned at a desired location inside the room. Then, by rotating the adjustment unit 23 and the wheels 22, the protruding height of the adjustment unit 23 is made greater than the protruding height of the wheels 22.

[0062] In the adjustment process, the floor section 2, which is composed of multiple divided floor sections 12, is horizontally adjusted by multiple adjustment units 23 (step S15). In step S15, for example, a spirit level is placed on the floor plate 21, which is composed of multiple divided floor sections 12. Then, the same process as in step S4 is performed. After the above process, the installation method of the shielding room 1A is completed.

[0063] After installing the shielded room 1A, the medical equipment is placed inside the shielded room 1A. For example, if the medical equipment is too large to be easily moved into the shielded room 1A, the medical equipment may be disassembled and its components moved into the shielded room 1A. In this case, the components moved into the shielded room 1A are assembled, and the medical equipment is then placed inside the shielded room 1A.

[0064] After performing step S13 or step S14, at least one of the wall section 3 and the ceiling section 4 may be fixed to the wall or ceiling of the room. This allows the shielded room 1A to be more firmly fixed to the room.

[0065] In this embodiment as well, multiple partitioned rooms 10 are manufactured outside the construction site, and the shielding room 1A is manufactured using the manufactured partitioned rooms 10. Then, the manufactured shielding room 1A is installed. This reduces the labor costs required when constructing the shielding room 1A and shortens the construction period. Consequently, construction costs can be reduced.

[0066] In the first embodiment, various methods for constructing a conventional shielded room were described. Firstly, there is a method of bringing in medical equipment before constructing the shielded room. Secondly, there is a method of dividing the room into an operation room for operating medical equipment and a shielded room, and bringing in the medical equipment from the operation room side to the shielded room. These methods can be adopted in a newly constructed medical facility S, but cannot be adopted in a medical facility S that has already been constructed. In contrast, in this embodiment, since each of the multiple divided rooms 10 is brought into the room, it can be applied even to a medical facility S that has already been constructed.

[0067] Furthermore, in this embodiment, multiple partitioned rooms 10 are manufactured, and the manufactured partitioned rooms 10 are brought into the room. Then, the shielding room 1A is manufactured inside the room using the brought-in partitioned rooms 10. For this reason, even if it is difficult to bring the manufactured shielding room 1A into the room, the shielding room 1A can be installed inside the room.

[0068] In this embodiment, each of the multiple divided floor sections 12 includes multiple wheels 22. Therefore, each of the multiple divided floor sections 12 can be easily moved, for example, and easily transported into a room.

[0069] [Differentiation] In the first embodiment, the adjustment process was performed after the installation process. However, the adjustment process may be performed after the manufacturing process and before the delivery process. In this case, for example, after placing the shielding room 1 on a horizontal surface, the floor section 2 is adjusted horizontally. Since the shielding room 1 is delivered into the room with the floor section 2 already adjusted horizontally, there is no need to adjust the floor section 2 horizontally at the construction site, and the construction period can be further shortened. By shortening the construction period, the medical facility S can be put into operation sooner. Alternatively, the adjustment process may be performed after the manufacturing process and before the delivery process, and another adjustment process may be performed after the installation process. In this case, even if the floor section 2 tilts relative to the horizontal surface during the delivery of the shielding room 1, the tilt of the floor section 2 can be corrected after the shielding room 1 is installed. Similar modifications are also possible in the second embodiment.

[0070] In the above embodiment, the floor section 2 includes a plurality of adjustment sections 23. However, the floor section 2 does not have to include adjustment sections 23. In this case, the floorboard 21 does not have to include the adjustment installation section 6. Also, each of the plurality of adjustment sections 23 is provided in the adjustment installation section 6A and not in the adjustment installation section 6B. However, each of the plurality of adjustment sections 23 may be provided in the adjustment installation section 6B. Also, some of the adjustment sections 23 may be provided in the adjustment installation section 6A, and the remaining adjustment sections 23 may be provided in the adjustment installation section 6B.

[0071] In the above embodiment, each of the multiple adjustment units 23 corresponds to each of the multiple wheels 22. However, the position of the adjustment units 23 can be changed as appropriate.

[0072] In the above embodiment, the adjustment part 23 is an adjustment screw, and the adjustment mounting part 6 includes a screwed portion 62. However, the configuration of the adjustment part 23 is not particularly limited as long as it can move back and forth in one direction. For example, the adjustment part 23 may be a telescopic rod that can move back and forth in one direction. In this case, the adjustment mounting part 6 may be a recess or through hole into which the telescopic rod can be inserted.

[0073] An example of how to install the shielding chambers 1,1A has been described, but the content and order of each step can be modified as appropriate without departing from the spirit of the present invention.
