This study aims at grasping the relativity between laborers' yangseng level and stress so as to present the groundwork for preventive oriental medicine approach in industrial health. The researcher prepared the questionnaire on general character, health-related yangseng level and chose 632 people to execute Autonomic balance test through heartbeat change. The collected material was analyzed by SPSS and tested by T-test, ANOVA. The general yangseng level average is 3.27, morality yangseng 3.91, sleep yangseng 3.39, mind yangseng 3.32, sex life yangseng 3.29, exercise yangseng 3.14, activities and rest yangseng 3.07, diet yangseng 2.95, seasonal yangseng 2.84. The highest is morality yangseng and seasonal yangseng is the lowest. In the aspect of yangseng level : Having a spouse, Non-smoking, Non-drinking, Regular exercising, Sufficient sleeping have higher yanseng levels. In Autonomic balance test, age from 35 to 40 has the highest autonomic activity and job period from 5 years to 10 years has the highest stress resistance. Non-smokers have high autonomic activity and stress resistance. Further, have low autonomic balance, stress index and fatigue strength. In the case of regular exercising person, he/she has high autonomic activity and stress resistance with low stress index. Regarding sleeping time, autonomic balance is the highest when he/she sleeps less than 6 hours. Stress resistance is the highest when he/she sleeps 7 hours and stress index is the highest when he/she sleeps 6 hours. After comparing the relativity between yangseng level autonomic balance test, only exercise yangseng has plus factor on autonomic activity and stress resistance and minus factor on stress ind ex and fatigue strength. Yangseng level has been affected by individual character and daily habits. Also stress is more influenced by daily habits than by individual character. We can find the relativity of exercise yangseng between yangseng and stress which suggests that we need to take measures to win over stress in individual health in the near future.

Purpose: This study was done to investigate the relationship between self esteem, stress, depression and school adjustment among adolescents who were victims of bullying and those who were not. Methods: The questionnaire included the Peer Victimization Scale (Callaghan & Joseph, 1995), Self-esteem Scale, (Rosenberg, 1965), Daily Hassles Questionnaire (Feiner, Ginter & Primavera, 1982) and Center for Epidemiological Studies-Depression (Radloff, 1977). Data from 738 questionnaires were analyzed using frequencies, means, ${\chi}^2$-test, t-test and logistic regression analysis with SPSS 14.0. Results: Victims of bullying accounted for 19.8% of the students. Significant differences were found for grade, school record, family living together, satisfaction with parents and satisfaction with friends between students who were victims of bullying and those who were not. Self esteem and school adjustment for the victims of bullying were lower than for those in the non-victim group, and stress and depression were higher. The logistic regression analysis revealed that school record, family living together, satisfaction with friends, self esteem, friend related stress, family related stress and depression were significantly associated with being a victim of bullying. Conclusion: The result of this study offer basic data for the development of intervention programs to prevent students becoming victims of bullying.

Background and objective: Various images from visual display terminals (VDTs) as well as living lighting are important parts of our daily life; thus, properly controlling the lighting environment - that is, illuminance, color temperature and good images from VDTs - can have a substantial effect on improving the mental health and work efficiency in everyday life. We examined electroencephalography (EEG) and heart rate variability (HRV) responses to various lighting conditions in 25 university students as they viewed images of a green landscape or traffic congestion. Methods: EEG was performed in darkness and when the room was illuminated with 10 different light-emitting diode (LED) color temperatures, while the EEG and HRV responses to green landscape or traffic congestion image stimuli were measured in darkness and during room illumination with three different LED color temperatures. Results: We found a significant difference between darkness and high LED illumination (400 lx) at 7 (CZ, F4, FZ, O1, O2, OZ, and T6) of 30 channels, while the alpha wave activity increased during darkness. In the second experiment, the green landscape image stimuli in the 30 lx-2600 K lighting condition elicited theta wave activity on the EEG, whereas the traffic congestion image stimuli under high LED illumination elicited high beta and gamma wave activities. Moreover, the subjects exhibited better stress coping ability and heart rate stability in response to green landscape image stimuli under illuminated conditions, according to their HRV. Conclusion: These results suggest that lower color temperatures and illumination levels alleviate tension, and that viewing green landscape image stimuli at low illumination, or in darkness, is effective for reducing stress. Conversely, high illumination levels and color temperatures are likely to increase tension and stress in response to traffic congestion image stimuli.

The current study was conducted to produce basic data for the policy establishment to improve the life satisfaction of residents in regional communities. The study subjected total 1,400 residents living in youngnam province in our nation for the survey by using convenience sampling. The survey took about 4 months started from March 1, 2007 to June 30, 2007. The abstract and conclusion of the result could be summarized as in below. 1. In subjective health status, 45.4% responded as normal, and the health status scored $2.68{\pm}0.67$ in 5 point scale(53.6 in 100 point scale). 2. The level of life satisfaction was found to show the score of $19.57{\pm}3.39$ in 30 point scale(65.2 in 100 point scale). Characteristically, the highest score was found in male in both age groups younger than 19 and in 20s, but lowest score was found in the age group in 40s(p<0.001). In the level of life satisfaction, 29.6% responded as satisfactory and 11.9% responded as not satisfactory. 3. In reviewing the life satisfaction by the health related characteristics, 65.7% of whom responded as very healthy answered satisfactory in life, and the life satisfaction was significantly high in peoples who do not smoke. However, the level was significantly higher in alcohol drinker than no alcohol drinker. People who have enough sleep tended to satisfy in their life, and the life satisfaction level of whom have leisure turned out to show superiorly high satisfaction level. 4. As the variables affecting on the life satisfaction, sex, age, education level, marital status, health status, stress level, life satisfaction level, healthy life activities and depression level were found, and the influence of these variables was 19.6%. As the above results demonstrate, the life satisfaction of residents in regional community was proportional to health status and highly affected by daily health life. So, the more attentions have to be made on health management and the self effort should not be neglected. Especially, since stress, depression level and leisure life did have effects on life satisfaction, more attentions have to be made on stress solving and on the development of leisure life programs. For the goal, the governments, related private organizations and specialized workforces have to make integrated efforts along with the health improvement project in large perspectives.

Objectives: The purpose of this study was to assess predictors of health-related quality of life (HRQoL) in elderly Asian American and non-Hispanic White cancer survivors. Methods: We conducted cross-sectional secondary data analyses using the combined datasets from the Surveillance, Epidemiology, and End Results program and the Medicare Health Outcomes Survey. Results: Elderly Asian American cancer survivors reported a lower mental HRQoL but a comparable physical HRQoL relative to elderly non-Hispanic White cancer survivors. Stress factors, such as comorbidities, difficulties with activities of daily living, and a history of depressive symptoms, along with coping resources like self-rated health and the ability to take the survey in English, were significantly associated with mental and physical HRQoL. Among elderly Asian American cancer survivors, a significantly lower mental HRQoL was observed among those taking the survey in the Chinese language. Conclusions: The findings suggest that race exerts a differential impact on HRQoL. Interventions should be designed to address the distinct cultural, linguistic, and systemic needs of elderly Asian American cancer survivors. Such an approach could assist in reducing cancer-related health disparities.

Meteorological disasters caused by climate change like heat, cold waves, and unusually long rainy seasons affect the milk productivity of cows. Studies have been conducted on how milk productivity and milk compositions change due to heat stress (HS). However, the estimation of losses in milk production due to HS and hereby environmental impacts of greenhouse gas (GHG) emissions are yet to be evaluated in Korean dairy farms. Dairy milk production and milk compositions data from March to October 2018, provided by the Korea Dairy Committee (KDC), were used to compare regional milk production with the temperature-humidity index (THI). Raw data for the daily temperature and relative humidity in 2018 were obtained from the Korea Meteorological Administration (KMA). This data was used to calculate the THI and the difference between the maximum and minimum temperature changing rate, as the average daily temperature range, to show the extent to which the temperature gap can affect milk productivity. The amount of milk was calculated based on the price of 926 won/kg from KDC. The results showed that the average milk production rate was the highest within the THI range 60-73 in three regions in May: Chulwon (northern region), Hwasung (central region), and Gunwi (southern region). The average milk production decreased by 4.96 ± 1.48% in northern region, 7.12 ± 2.36% in central region, and 7.94 ± 2.57% in southern region from June to August, which had a THI range of 73 or more, when compared to May. Based on the results, the level of THI should be maintained like May. If so, the farmers can earn a profit of 9,128,730 won/farm in northern region, 9,967,880 won/farm in central region, and 12,245,300 won/farm in southern region. Additionally, the average number of cows raised can be reduced by 2.41 ± 0.35 heads/farm, thereby reducing GHG emissions by 29.61 ± 4.36 kg CO₂eq/day on average. Overall, the conclusion suggests that maintaining environmental conditions in the summer that are similar to those in May is necessary. This knowledge can be used for basic research to persuade farmers to change farm facilities to increase the economic benefits and improve animal welfare.
