Purpose : To investigate and compare the characteristics of menstruation in the shift workers and the day workers, and present guidelines for health promotion of the shift-working women. Methods : Questionnaires including general health condition and QSCC II were distributed to shift-working women and day-working women in one university hospital in Gyeonggi-do and 36 questionnaires of shift-working women and 33 of day-working women were analyzed. Results : Day workers were about 5 years older than shift workers on average. There was more irregularity of menstrual cycle and period in day-working group but it is thought to incorrect because of the age problem. There were more women who have dysmenorrhea in day-working group, but the proportion of dysmenorrhea which continues more than 72 hours -which is very suggestive of secondary dysmenorrhea- was higher in shift-working group. Average VAS of dysmenorrhea was nearly the same in two groups. The life of shift-working group was lesser satisfactory than that of day-working group. There were more sleep disturbances in the shift-working group. Sasang constitution was analyzed in both group using QSCC II, and Taeumin were more in shift-working group. Conclusion : As the number of shift-working women increases, needs for oriental medical treatments would increase because it is more natural and lesser invasive managements which women are very interested in. So it is thought to be necessary to understand health problems of shift-working women, and prepare guidelines for managements and treatments to promote the health of shift-working women.

Background: Prolonged use of visual display terminal (VDT) can cause eyestrain, dry eyes, blurred vision, double vision, headache and musculoskeletal symptoms (neck, shoulder, and wrist pain). VDT working hours among workers have greatly increased during the coronavirus disease 2019 (COVID-19) pandemic. Therefore, this study aimed to investigate the relationship between VDT working hours and headache/eyestrain in wage workers using data from the sixth Korean Working Conditions Survey (KWCS) (2020-2021) conducted during the COVID-19 pandemic. Methods: We analyzed the sixth KWCS data of 28,442 wage workers aged 15 years or older. The headache/eyestrain that occurred in the last year was assessed. The VDT work group included workers who use VDT always, almost always, and three-fourth of the working hours, while the non-VDT work group included workers who use VDT half of the working hours, one-fourth of the working hours, almost never, and never. To analyze the relationship between VDT working hours and headache/eyestrain, the odds ratios (ORs) and 95% confidence interval (CI) were calculated using logistic regression analysis. Results: Among the non-VDT work group, 14.4% workers experienced headache/eyestrain, whereas 27.5% workers of the VDT work group experienced these symptoms. For headache/eyestrain, the VDT work group showed adjusted OR of 1.94 (95% CI: 1.80-2.09), compared with the non-VDT work group, and the group that always used VDT showed adjusted OR of 2.54 (95% CI: 2.26-2.86), compared with the group that never used VDT. Conclusions: This study suggests that during the COVID-19 pandemic, as VDT working hours increased, the risk of headache/eyestrain increased for Korean wage workers.

In this paper. nuclear characteristics of TRIGA Mark-III has been analyzed in detail for six different fuel options. Presently, 70 w/o enriched FLIP fuels are adopted for TRIGA core to improve fuel lifetime. However, such highly enriched fuels are not easily obtained due to nonproliferation treaty. This research examines the possible substitution for FLIP fuels with high density fuels without reducing the nuclear performance. This work will provide long-time plan for TRIGA operation.

Purpose: This present study has been conducted on female workers' shorter working hours in order to look into their fatigue level and the correlation between fatigue and working hours. Method: We surveyed 237 respondents using a questionnaire from June 1st to June 20th, 2005. Results: The means of total fatigue complaint was 3.45. The fatigue level was significantly higher in the lower age group, unmarried group, manager group and shorter working duration group. And the fatigue level was significantly correlated to working hours and work intensity. In the results of stepwise multiple regression, factors affecting the fatigue level were the change of work intensity, age, regular diet habit, working hours and the type of occupation. Conclusion: It is necessary to prepare the health promotion programs, which can reduce female workers' fatigue level and relieve the intensity of their works.

This study analyzed the relationship between stressful life events and state of mental health among middle class non working housewives and working housewives (104 pair) by age from June 5 to June 19, 1995 in seoul. The results of this study are as follows. 1. The degree of stressful life events was not statistically significant, but the degree working housewives group (Mean 1. 448) was higher than that of non-working housewives group (Mean 1.509). 2. The state of mental health showed statistically significant (p<. 01) the degree of non-working housewives group (Mean 7.36) was higher than that of working housewives (Mean 5.52). 3. The correlation between stressful life events and state of mental health showed natural in both non-Working housewives group (r=.497, p<.001) and working housewives (r=.532. p<.000), so increased stress is related to lower mental health. 4. The degree of stressful life events based on social psychological factor, showed statistically significant (p<.05) in the feeling of life, and the state of mental health was statistically significant in the part of feeling of life (p<.05) and subjective health state (p=.000)

Background: Because income and working hours are closely related, the health impact of working hours can vary according to economic status. This study aimed to investigate the relationship between working hours and the risk of poor self-rated health according to household income level. Methods: We used the data from the Korea National Health and Nutrition Examination Survey VI and VII. The information on working hours and self-rated health was obtained from the questionnaire. After stratifying by household income level, the risk of poor self-rated health for long working hour group (≥ 52 hours a week), compared to the 35-51 working hour group as a reference, were calculated using multiple logistic regression. Results: Long working hours increased the risk of poor self-rated health in the group with the highest income, but not in the group with the lowest income. On the other hand, the overall weighted prevalence of poor self-rated health was higher in the low-income group. Conclusions: The relationship between long working hours and the risk of poor self-rated health varied by household income level. This phenomenon, in which the health effects of long working hours appear to diminish in low-income households can be referred to as the 'poor worker's long working hours paradox'. Our findings suggest that the recent working hour restriction policy implemented by the Korean government should be promoted, together with a basic wage preservation to improve workers' general health and well-being.
