The purpose of this study is to identify the impacts of the 5 day workweek system on the family resource management. This family resource may be divided into four spheres (family relationship, household economy, household labor, and leisure activity). Data were obtained from 182 husbands and 182 his wives. He is employed in a company which have fully introduced the 5 day workweek system. Descriptive Statistics(frequency and mean) was used for examining a demographic characteristics and a thought of the system, and t-test analysis for the difference by sex and before and after. According th the results of this study, first, after operation of the 5 day workweek system, the couple have more conversation with each other than before. Second, in reality, the income was not decreased beyond expectation. During the new holiday, the couple take out to go on a visit, to do their shopping, and to eat out. Third, the household labor time is different by sex. But the husbands is reported that they are participated more in hanging out the laundry, cleaning, and care for children than before. Forth, the family leisure activity of the husbands in comparison with individual activity and wives increased more than before.

This study was conducted to identify the educational need of pregnant women, and to evaluate the effect of the 2-hour childbirth class provided by researchers. The subjects were composed of 183 pregnant women who participated voluntarily in the 2-hour childbirth class, and the data were collected by self reporting structured questionnaire designed by researchers. The data were analyzed with descriptive statistics, paired t test, and McNemar test by SPSS pc program. The results were as follows ; 1. Mean age of th subjects was 27 and most subjects graduated from the high school and the college. 80.3% of the subjects had nuclear family. 82.5% of the subjects were full time housewives. 2. 85.8% of the subjects were ipara. Though 71.6% of the subjects might have antepartal care in the clinic, 67.2% of the subjects had no chance to participate in the childbirth class before this study. 3. Subject's health and lifestyle, especially related to eating habits, were changed in the antepartum period. We found that the pregnancy affected positively on health and lifestyle of the women. Over 75% of the subjects became to understand the progress of labor, breath methods during the labor, and perineal exercise. Most subjects changed to think that they could control their body more actively and positively during the labor after participating in the childbirth class. 93.4% answered that 'childbirth class was necessary and important'. Most subjects wanted to be taught the contents, such as postpartum care, breast feeding, and infant care in the childbirth class. In conclusion, pregnant women to attend the childbirth educational program with their husband, and the 2-hour childbirth class provided by the researchers very effective in many aspects. Therefore we anticipated that the childbirth class on basis of pregnant women's needs will contribute to improvement of pregnant women's health and well-being during the labor.

Since most people spend a large majority of their time indoors (at least in the industrialized countries), indoor air may affect human health more than outdoor air. This study was carried out to characterize the reference and equivalent methods against the low volume method which was promulgated by the Ministry of Health and Social Affairs. The Laser and Piezo air sampler offer the advantage of real time data and low labor costs. The arithmetic mean concentrations were found to be 102.9% (Laser-2 min method) and 65.9% (Piezo method) against low volume method (100%). The statistical analysis procedure for this comparision is linear regression. The linear regression line of low volume method had slopes of 0.5487 and 0.9697 and Y intercepts of 0.0266 and 0.0110 $\mu$g/m$^3$ about Laser (2 min) and (24 h) method respectively. And the correlation coefficients were 0.7271 and 0.9433.

This study examines work and family life of married women employed in a manufacturing industry. Data were gathered from the use of fact-to-face interview method from a sample of 230 married working women. The major findings of this study can be summarized as follows : (1) With high rates of change of job, most of the respondents remain unstable in their working situation. It was shown that the important factors influencing job satisfaction of married women are women's life cycle, degree of contribution of wife's income toward total family income, and husband's attitude toward wife's empolyment. The degree of job satisfaction is also strongly influenced by labor structural factors such as pay, work environment and fringe benefits. (2) The amount of household labor time was limited by job-related factors rather than by family-related factors, because among these working women employment itself is necessarily for their subsistance. (3) It was shown that wives participated more actively in their marital communications than their husbands. Most of the respondents showed the syncratic type of the decision making patterns, but this results does not necessarily mean wives exercised an equal power with their husbands. The economic factors and the emotional instability of the husband are the ones mostly influencing marital conflicts of the employed women. It was found that the respondents easily revealed marital conflicts related to personal problems of their husbands(such as extramarital affairs, gambling and alchoholism). However, they tried to overcome the structural conflicts related to authoritarian attitudes of their husbands or economic problems without any complaints. (4) Mothers have difficulty in controlling their adolescent children, due to the weakening of parental authority. Although most of the respondents perceived their employment as having negative impacts on their children, they still have high expectations toward their children. Inspite of low degree of father role expectations and facther role performance of their husbands, most of the respondents anticipated expressive roles as well as traditionally instrumental role from their husbands. Finally, these findings would help us determine family welfare policies in Korea. Improvements in paid and household labor structure of married women should be accomplished at the national level. Also, the acting programs for parent education, marital councelling services, and law enforcement for equal employment between men and women should be provided in our society.

To investigate the affecting factors to the fatigue and subjective symptoms of adult women, the author analyzed the data from 300 women from 3 groups, manufacture workes, clerical workers and service workers, from august 31, 1993 to the September 30, 1993. Followings are the results there from. 1. For the physical symptoms of fatigue, more than 50 % of respondens comiained were "eye strain" with 73.7 %, "malaise" with 67.0 % "went lay down side" with 60.7 %, "yawing" with 60.3 % and "feel sleep" eith 50.3 % in that order. There was no statistically significant difference between labor woker group, but the fatiger rate was highest among office group. For the mental symptoms. There was no symptom over 50 % of responders complained. For the neurotic symptoms, more than 50 % of respondents complained were "backache" with 53.7 %, "headache" with 49.7 % "shoulder pain" with 54.0 % and "unconfortable" with 43.3 %, in that order, "backache" was higest in manufacture group, but the other symptoms were highest among office group. 2. For the most fatigue weekday, most women answered monday with 56.0 % thursday with 16.3 % and friday with 12.0 % in that order, but saturday was 2.0 %, and sunday was 2.05 labor worker group answered monday was the most fatigue day. 3. 37.7 % of respondents answered afternoon was the most fatigue hours, but 22.0 % was answered evening difference among groups. 4. Nothing to do with the general characteristics, such as age, residence, sleep hours, personality, health status, and exercise, and working conditons such as means to attend office, time to attend office, job satisfaction, work hours, and work years, the mean scores of subjective symptoms of fatigue was highest among office group.

The purposes of this study were to develop standardized indices of staffing needs in each school, foodservice system through work sampling methodology . Conventional school foodservices were classified into 5 groups depending on size of meals served. Commissary school foodservices were also classified into 5 groups by cluster analysis using number of meals served, number of satellite schools, and time for transportation of food. Work measurement through work sampling methodology was conducted in 15 conventional and 21 commissary foodservices during 3 consecutive days from September to October in 1995. Statistical data analysis was completed using the SAS programs for descriptive analysis, cluster analysis, and simple linear regression. The results were as follows : Average points of leveling factors of conventional and commissary foodservices were 1.066 and 1.061 , respectively. Mean labor hours per work force was 328 minutes and 366 minutes in conventional and commissary foodservice , respectively. Standardized work time was calculated using leveling factor, ILO allowance rate (175) , and observational work time. The model for standardized indices of staffing needs was developed based on simple linear regression in each school foodservice system. In conventional school foodservice systems(for 100-1,900 meals per day) standardized staffing needs=3.2497 +0.005267$\times$number of meals served (F=273.1, R-square 0.9750, p<0.001). In commissary school foodservice systems (for 200-1,600 meals per day ) Standardized staffing needs=3.393384 +0.0063$\times$number of meals served (F=30.78, R-square 0.6580, p<0.001).

Climate change has resulted in increased frequency and intensity of heat waves, which poses a significant threat to the health and safety of construction workers, particularly those engaged in labor-intensive and heat-stress vulnerable working environments. To address this challenge, this study aimed to propose an interpretable machine learning approach for forecasting personal heat strain by considering the cumulative effect of heat exposure as a situational variable, which has not been taken into account in the existing approach. As a result, the proposed model, which incorporated the cumulative working time along with environmental and personal variables, was found to have superior forecast performance and explanatory power. Specifically, the proposed Multi-Layer Perceptron (MLP) model achieved a Mean Absolute Error (MAE) of 0.034 (℃) and an R-squared of 99.3% (0.933). Feature importance analysis revealed that the cumulative working time, as a situational variable, had the most significant impact on personal heat strain. These findings highlight the importance of systematic management of personal heat strain at construction sites by comprehensively considering the cumulative working time as a situational variable as well as environmental and personal variables. This study provided a valuable contribution to the construction industry by offering a reliable and accurate heat strain forecasting model, enhancing the health and safety of construction workers.

An investigation was made of the effect of carrot variety and harvest time (DAP) on the composition of carotenoids and the Retinol Equivalent value by column chromatography, and of the relation of the total carotenoid content to the Retinol Equivalent by regression analysis. The results are summarized as follows : 1. There were very significant differences of total carotenoid, ${\alpha}-carotene,\;and\;{\beta}-carotene$ contents among carrot varieties and between two harvest times(90 DAP, 99 DAP). Especially, each component of carotenoids in carrots harvested at 99 DAP attained higher concentrations than 90 DAP. 2. Retinol Equivalent value showed the tendency to increase as the numbers of DAP incr The Shindaehyung-Ochon and Hongshim-Ochon varieties had the highest RE. value. 3. In the composition of carotenoids and Retinol Equivalent value, the Shamgae-Ochon variety had the nearest value to the mean of all variety. Therefore, it is most reasonable to use the Shamgae-Ochon variety for the analysis of vitamin A value in carrots. 4. The regression of the totel carotenoid (x) to the Retinol Equivalent (y) was y = 0.074 + 0.12x $(r^2$ = 0.91). So, if total carotenoid content is determined, R.E. value can be predicted by this regression equations, saving time and labor.
