[Target area (work area and other areas)]
Target areas to be entered as work areas and other areas include not only Japan but also foreign countries. The work area means the area where the work site is located, and the other area mainly means the area where the workers are from. In this embodiment, for example, wide areas such as prefectures are further limited and stored in the storage device 4 as area data so that even cities can be selected.

[WBGT]
WBGT is a heat index (unit: °C) for evaluating heat stress due to a hot environment. The risk of heat stroke increases as the measured value of WBGT increases.

[Work area WBGT reference value]
Work area WBGT reference values are data obtained by observing WBGT in each region (WBGT reference value data by region) provided in advance as standard data, and are referred to as data corresponding to the work area. is. The work area WBGT reference value differs from work area to work area, and tends to be generally higher in the southern region than in the northern region, for example.

In the present embodiment, the other region WBGT reference values are displayed on the output result display screen, especially the values corresponding to August. As for the other area WBGT reference values, values corresponding to each month from April to October may be displayed on the output result display screen.

[Working intensity]
Work intensity is also called physical work intensity, and is the intensity of work activity assumed at the work site of the worker, classified according to the metabolic rate level. Work intensity is categorized in ascending order as ``rest'', ``low metabolic rate'', ``moderate metabolic rate'', ``high metabolic rate'', and ``very high metabolic rate'', and is selected as an input item on the input operation display screen. It is possible.

[air flow]
The airflow indicates the strength of the wind assumed at the worker's work site. If the wind is assumed to be strong to some extent, it is assumed that there is an airflow, and if it is assumed that the wind is not so strong, it is assumed that there is no airflow. The presence or absence of airflow can be selected as an input item on the input operation display screen.

[clothing]
Clothing indicates work clothing that is assumed to be worn at the work site. Clothing, for example, "work clothes (long-sleeved shirt and trousers)", "cloth (fabric) coveralls", "two-layer cloth (fabric) clothing", "SMS polypropylene Coveralls", "Polyolefin Coveralls", and "Vapor Impermeable Coveralls for Limited Use" can be selected as input items on the input operation display screen.

[Correction value]
The correction value is internally determined according to the difference between the work area WBGT reference value and the other area WBGT reference value, the work intensity, the presence or absence of airflow, and the clothes. The larger the difference between the work area WBGT standard value and the other area WBGT standard value, the larger the correction value, and the greater the work intensity, the larger the correction value. The correction value becomes large, and the larger the degree of influence of clothing on heatstroke, the larger the correction value.

Further, as shown in FIG. 3B, the storage device 4 functions as a WBGT correction value/coefficient data storage means 310 for storing coefficient data in which coefficients are set according to BMI (different types of A to F depending on the degree of obesity). is pre-stored in Furthermore, as shown in FIG. 3C, the storage device 4 functions as a WBGT correction value/coefficient data storage means 310 for storing coefficient data in which coefficients are set according to blood pressure (by type A to F according to systolic blood pressure). is pre-stored in Such coefficients are displayed on the input operation display screen.

[Work area WBGT reference value for each worker]
The worker-specific work area WBGT reference value is obtained as a result of multiplying the work area WBGT correction reference value by the above coefficient. As for the work area WBGT reference value for each worker, values corresponding to each month from April to October are displayed on the output result display screen.

[Acclimatization]
Acclimatization (heat acclimation) is the gradual acclimatization of the body to the heat over a period of days.

[Baseline acclimation period]
The reference acclimatization period is determined in advance as reference acclimatization period data, which is the standard number of days required for acclimatization for each region and month. For the standard acclimatization period, for example, the number of standard days required for acclimatization in each month from April to October in a predetermined work area is set. The standard number of days required for acclimatization (reference acclimatization period) can be specifically determined as follows. For example, for workers who work at the work site in advance, from the day they enter the work site, before work in the morning, at the end of work in the morning, at the start of work in the afternoon, at the end of work in the evening, etc., four or more times a day. , Conduct a questionnaire to check the vitals, and check the physical condition of the worker. For this check result, for example, a so-called box plot is created to evaluate variations. When creating a boxplot, the number of days for which acclimation is recognized to be completed is estimated for each worker according to their physical condition, and the number of people counted for each estimated number of days is the minimum value, the first quartile, and the median value. , 3rd quartile, and maximum value, resulting in 1st quartile, median, and 3rd quartile. % is regarded as "acclimatization", 80% or more and less than 90% is regarded as "almost acclimation", and 70% or more and less than 80% is regarded as "slightly acclimation". In the case of "acclimatization", the standard number of days required for acclimation (reference acclimation period) is determined, for example, 7 days, which corresponds to the median value. = determined on day 8, and in the case of "almost acclimated" median +2 = determined on day 9. Data relating to the reference acclimation period obtained by sampling through a questionnaire or the like in advance in this way is stored in advance in the storage device 4 functioning as the reference acclimation period data storage means 330 .

The acclimatization period correction value is for correcting the reference acclimatization period according to the worker-specific work area WBGT reference value. The acclimatization period correction value is set to ±3 (days) corresponding to each month from April to October in a predetermined work area, for example. Data relating to the acclimation period correction value is stored in advance in the storage device 4 functioning as the reference acclimation period data storage means 330 . By adding this acclimation period correction value to the reference acclimation period, an optimum acclimation period, which will be described later, is obtained. Note that the acclimatization period correction value may be set in advance according to the work area WBGT reference value.

[Optimal acclimation period]
The optimum acclimatization period is obtained mainly as a result of adding the acclimatization period correction value to the reference acclimatization period. In this embodiment, the optimum acclimatization period is displayed on the output result display screen with values corresponding to each month from April to October. It should be noted that the optimum acclimatization period may be displayed on the output result display screen only for August, which is assumed to be the longest.

For example, no background color is below 25°C, yellow background color is 25°C or higher and lower than 28°C, light red background color is 28°C or higher and lower than 31°C, and 31°C. These are displayed with a dark red background. Also, in the work area WBGT reference value, work area WBGT correction reference value, work area WBGT reference value by worker, and work area WBGT reference value by worker by month graphs, the maximum value and the average value are displayed separately. The work area WBGT reference value graph for each worker by month is displayed by a polygonal line with the month on the horizontal axis and the temperature (° C.) on the vertical axis. As for the other area WBGT reference value, only the value in August, which is estimated to be the maximum, is displayed, but each value may be displayed for each month within a specified range, for example. For the optimum acclimatization period, each value obtained for each month within a specified range (eg, April to October) is displayed.

Next, the acclimatization evaluation process executed by the CPU 1 of the acclimatization evaluation apparatus will be described with reference to FIG. FIG. 6 is a flow chart showing the acclimatization evaluation process.

First, in step S1, the CPU 1 causes the display device 8 to display an input operation display screen as shown in FIG.

Next, in step S2, the CPU 1 determines whether essential information (essential information) has been input for each input item on the input operation display screen. Mandatory information includes the worker's name, time (month, period), work area, physical work intensity, airflow, clothing (work clothes), age, BMI, blood pressure, hometown (domestic), etc. However, the processing may proceed even if any of the physical work intensity, airflow, clothes (work clothes), age, BMI, and blood pressure are not input. When the essential information is input (step S2: YES), the CPU 1 proceeds to the next step S3. If any of the essential information is not entered (step S2: NO), the CPU 1 repeats the process of step S2 until the essential information is entered.

Next, in step S3, the CPU 1 causes the display device 8 to display an output result display screen as shown in FIG. 5 according to the input essential information.

Specifically, the CPU 1 reads the corresponding work area WBGT reference value data from the storage device 4 based on the information input as the work area, and also reads out each piece of information on the input correction value (physical work intensity, airflow, clothing, age) is read out from the storage device 4, and the correction value is added to the work area WBGT reference value data thus read out. The values thus obtained as the result of the addition are displayed in a monthly table as work area WBGT correction reference values.

The CPU 1 also reads coefficients corresponding to the input coefficient-related information (age, BMI, blood pressure) from the storage device 4, and multiplies the work area WBGT correction reference values by these coefficients. The values thus obtained as multiplication results are displayed in monthly tables and graphs as worker-specific work area WBGT reference values.

Further, the CPU 1 reads out the corresponding other area WBGT reference value data from the storage device 4 based on the information input as the region of origin (other area), and displays the value corresponding to August of the other area WBGT reference value data. . Then, the CPU 1 calculates the difference between the worker-specific work area WBGT reference value for each month and the other area WBGT reference value, and calculates the corresponding reference acclimatization period based on the information input as the work area. and the acclimation period correction value corresponding to the difference are read out from the storage device 4, and the optimum acclimation period is calculated by adding the acclimation period correction value to the reference acclimation period, and is shown in a monthly table. display.

Next, in step S4, the CPU 1 uses the input worker's name as an index and outputs corresponding input information (time, work area, physical work intensity, airflow, clothes, age, BMI, blood pressure, hometown) and output The resulting information (work area WBGT reference value, work area WBGT correction reference value, work area WBGT reference value for each worker, optimum acclimation period) is stored in the storage device 4 as evaluation data for each worker.

Next, in step S5, the CPU 1 determines whether or not the print button has been operated on the output result display screen to request printing. If printing is requested (step S5: YES), the CPU 1 proceeds to the next step S6. If printing is not requested (step S5: NO), the CPU 1 terminates this acclimatization evaluation process.

Next, in step S6, the CPU 1 executes print processing. In the printing process, the contents displayed on the output result display screen are printed by the printing device 9 .

According to this acclimatization evaluation process, the work area WBGT reference value for each worker is appropriately obtained according to the work intensity, airflow, clothing, age, BMI, and blood pressure for each worker. The work area WBGT reference value and the other area WBGT reference value corresponding to the worker's home area are displayed side by side for each worker on the output result display screen. Further, on the output result display screen, the optimum acclimatization period for each worker is displayed by correcting the standard acclimatization period according to the work area WBGT standard value for each worker. As a result, it is possible to quantitatively and in advance evaluate the optimum period required for acclimatization calculated according to the numerical difference between the displayed work area WBGT reference value for each worker and the other area WBGT reference value. It can be used effectively in advance as a preventive measure against hypothermia or hypothermia.

Although the present invention has been described using the embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiments. It is obvious to those skilled in the art that various modifications or improvements can be made to the above embodiments. Moreover, it is clear from the description of the scope of the claims that the forms with such modifications or improvements can also be included in the technical scope of the present invention.

Although the above embodiment has been described as being suitable for measures to prevent heat stroke, the present invention can also be applied to measures to prevent hypothermia. For example, a cold index for evaluating low-temperature stress due to extremely cold environments is stored in advance as reference value data obtained by observing each region, and similar acclimatization evaluation is performed using such reference value data. By performing the processing, it may be possible to quantitatively and in advance evaluate the optimal period required for acclimatization for persons such as police officers, firefighters, and Self-Defense Force personnel who are active in extremely cold environments.

In the above-described embodiment, regional WBGT reference value data, WBGT correction value/coefficient data, reference acclimation period data, programs for acclimation evaluation processing, and the like are stored in the storage device 4 in advance. may be downloaded from a server on the Internet each time to execute the acclimatization evaluation process.

In the above embodiment, the optimum acclimatization period is calculated by adding the acclimatization period correction value corresponding to the work area WBGT reference value for each worker to the reference acclimatization period. An acclimation period correction value corresponding to the WBGT reference value may be set in advance, and such an acclimation period correction value may be added to the reference acclimation period to calculate the optimum acclimation period.
