According to the Labor Standard Law in Japan which was enacted after World War II in 1947, all work hours for adult men, women, and youth were set at a maximum of eight hours per day and forty-eight hours per week. In other words, a six-day work week, with only one-day off, was set. Now we are in the full five-day and two-day off school system. The five-day school week influences on our home life. Students are highly enthused by the new system, in looking forward to their personal time they now have to play with friends, to relax, or just watch TV. To implement this new five-day school system positively and effectively, we should see the point at issue related to the two-day off system from a different angle, which suggests that we should see far ahead into the future.

These days, people have changed their attitude and understanding of the tenn leisure. Since the introduction of the five-day work week system in Korea, people's leisure activities have changed greatly. The purpose of this study was to examine how leisure activities have changed after the introduction of the five-day work week and to find out the variables which influence the way Koreans spend their leisure time. The conclusion and results of these analyses are follows: The five-day work week system increased people's leisure hours, but they were still working more than 40 hours per week and their satisfaction from leisure activities was more influenced by other variables than the enforcement of the five-day work week system. Among the variables influencing the satisfaction from leisure, only those with high income and educational backgrounds were affected by the five-day work week. To conclude, there is a necessity for direction suggestions and political support to utilize leisure time positively.

This study aimed to identify parents' experiences of child-rearing on Saturday with no class as well as their perceptions and demands on the Five-day School Week system. The study participants were 640 parents with first to second grade children. The major results were as follows: First, parents were generally satisfied with the Five-day School Week System. Second, the Five-day School Week System increased fathers' role-sharing on the Saturday with no class. It was also related with some of the demographic variables and the Five-Week Workweek System of the father and the mother. Third, both the fathers and mothers had more parenting stress on Saturdays with no class than on Saturdays with classes. Their parenting stress on Saturdays with no class was related with some demographic variables and work flexibility.

This study investigates the influences of factors such as type and degree of family leisure among parents with five day work weeks on adolescents' perceived family strengths. Its findings are based on questionnaires collected from 525 male and female parents of middle school students. Factor analysis and MANOVA were employed for data analysis and $Scheff{\acute{e}}$ tests for post-hoc analysis. The main findings were as follows. First, adolescents whose parents work five days a week were at a higher level than other adolescents in terms of finances, family ties, communication, and social ties. Second, there were no significant differences concerning adolescents' family strength by type of family leisure. Third, adolescents with more family leisure activities scored higher than others in the areas of manageable strengths, financial levels, family ties, communication, and family social ties. Fourth, among families following the five day working system, adolescents who had more family leisure activities scored higher than the others in regards to manageable strengths, financial levels, family ties, communication, and family social ties. Additionally, where adolescents thought they had fewer family leisure activities, family-oriented adolescents tended to be engaged in higher physical-activity-oriented and hobby-oriented activities in relation to manageable strengths, financial level, family ties, and communication and hobby-oriented adolescents engaged in higher than average amounts of physical-activity, strengthening family social ties in the process. Fifth, concerning families not adhering to the five day working system, adolescents who had more family leisure activities scored higher than others in terms of manageable strengths, financial levels, family ties, communication, and family social ties. As the above results indicate, family leisure activities appear to be a key factor influencing family strength. Therefore, further support should be extended toward developing new forms of family leisure and additional studies should be devoted to the subject.

The purpose of this study is to investigate the present conditions of the night work and shift work systems in the heavy chemical industrial complexes found in Changwon, Masan, and Chinhae. Korea. We will attempt to define and classify their problems; and to discover further ways to improve their systems. Fifty production factories were carefully selected as the subjects for this study. The shift systems were classified into five categories. The consecutive night shifts were long in almost all cases with 6 days (36 factories) and 7 days (13 factories). It was found that the night work of about] 2 hours continues for a long period in the weekly rotation full-day shift systems and the night-including non-full-day shift systems, and there was no holiday during a shift cycle in the continuous full-day shift systems. The work time in most shift systems was longer than the 44-hours/week permitted by Korean law. Considering the characteristics of these various types of shift systems, the most essential thing to reduce the shift workers' work load may be to shorten their working hours and improve the schedule of shift systems. It is highly recommended as a fundamental solution. to reduce the portal-to-portal hours from 12 to 8 in the night-including non-full-day shift systems and the weekly rotation full-day shift systems, and at least to employ a 4-team 3-shift system in the continuous full-day shift systems. In addition to this, it should from now on be taken as a goal to restructure the types of shift systems by taking such measures as avoiding continuous night work if possible, providing sufficient off-duty intervals both before and after night shift, providing increased opportunities for workers to nap during night work. and increasing the number of holidays.

Objectives: There is limited data regarding the toxicity of methylcyclohexane, despite its wide use in rubber adhesives, paint diluents, and cleansing agents. This study aimed to verify the toxicity and influence on the reproductive system of methylcyclohexane after its repeated injection in Sprague Dawley (SD) rats. Methods: Methylcyclohexane was injected subcutaneously into male and female SD rats once a day, five times a week, for 13 weeks at different doses (0, 10, 100, and 1,000 mg/kg/day) for each group. The toxicity of testing material was verified by observing the change in body and organ weight, hematological change, pathological findings, and effect on the reproductive system at each different concentration. Results: In the 1,000 mg/kg/day group, there were cases of animal deaths. In animals that survived, hematological changes, including a decrease in the red blood cell count, were observed. A considerable weight gain or loss and pathological abnormalities in the liver, kidney, and other organs were found. However, the 10 and 100 mg/kg/day groups did not cause deaths or other specific abnormalities. In terms of reproductive toxicity, there were changes in hormone levels, including a significant decrease in hormones such as estradiol and progesterone (p < 0.001) in male animals. Menstrual cycle change for female animals did not show concentration dependency. Conclusion: When injected repeatedly for 13 weeks, methylcyclohexane proved to be toxic for the liver, heart, and kidney at a high dose. The absolute toxic dose was 1,000 mg/kg/day, while the no observed adverse effect level was less than 100 mg/kg/day. The substance exerted little influence on the reproductive system.

주5일 근무제가 본격적으로 시행됨에 따라 여가에 대한 관심이 증가함에 따라 기존에 행하지 못한 교외나 근거리, 원거리 통행이 비례적으로 증가함에 따라 관광지나 위락시설이 인접해있는 도로의 구간은 심한 정체가 발생될 것으로 예상된다. 이에 따른 문제를 고려할 때 이러한 여가 통행의 증가로 정체가 발생한 구간을 판별하고 분류하여 이에 대한 도로교통 운영 및 정비 등의 대응방안이 필요할 것으로 판단된다. 따라서 본 연구에서는 고속도로의 TCS자료의 구간단면 교통량을 이용하여 고속도로의 여가성 도로구간을 주성분분석을 통하여 판별하는 연구를 수행하여 여가성 도로와 비여가성 도로 통행특성 관계를 각 변수들의 특성을 규명하여 연구 수행의 근거를 제시하였다. 또 이러한 특성을 기반으로 변수들의 상관행렬을 이용한 주성분분석을 수행하여 주성분 점수를 산출하였다. 그 결과 고속도로의 총 197개의 구간 중 여가성 도로구간과 비여가성 도로구간을 추출하여 분류하고, 각 변수들의 비여가성 도로구간과 여가성 도로구간으로 분류할 수 있는 기준을 제시하였다.
