The purpose of this study was to investigate work stress and identify the various factors affecting stress in married women in working manufacturing industries. Data were collected between March 31 and June 28, 2003 from 266 married women working in 10 manufacturing industries in Korea. The self-administered questionnaire included general characteristics. social support, and work stress. The data were analyzed using descriptive statistics, t-test, ANOVA, and Cronbach's alpha. SPSS/win 11.0 was used to assist analysis. The results of the study are as follows: 1. Scores for work stress in the field of sub-categories 2. Perceived work stress was significantly different according to salary, behavior type, discomfort related to menstruation, consumption, duty type, job stability, weekly work time and family, 3. Social support had a significant negative relationship with work stress. Accordingly, stress management for married working women will be more successful if interventions not only address each person's unique needs, for example, control of perimenstrual discomforts and health behavior change, but also are accompanied by organizational management strategies and policies, for example, improvement of work environment and nursery facilities.

In this study we tried to give a decision on propriety of working conditions, to present ideas on reducing work loads, and to grope for efficiency of agricultural works. For this we examined the actual working conditions of cultivating welsh onion in the summer ground. And we improved harmful factors that affect farmer's health by considering results of previous study and farmer's subjective sensation. And we measured. compared, and analyzed the farmer's work loads before and after improvement. The results of this study are as follows ; 1. According to examine the actual working conditions of cultivating welsh onion in the summer ground, farmers have experienced physical and mental chronic fatigue on the basis of farmer's appel to eye - fatigue and sun - burned skin on hot working environment including excessive ultraviolet rays, the rough ground condition, inconsistent arrangement of working stand and sorter, heavy - weared habits, and unsuitable working posture. 2. When we improved harmful factors that affect farmer's health, conformed the effects on important work efficiency index such as heart rate, electromyovolume, body temperature, and microclimate inside clothing and work loads were decreased by eliminating the hillock and obstacles of ground, decreasing the clothing weight, using proper clothing appliances such as hat and sunglasses, controlling height of working stand and sorter suitably, improving the working postures and methods as using assistant appliances, alloting the working time and sequence effectively and presenting the light gymnastic exercises and rest for fatigue restoration.

This study was conducted to provide a counterplan for preventing so celled “plastic house syndrome” revealed among farmers spending much time in the plastic houses. For this, working environment inside a plastic house was observed. Then, experiments were carried out mostly in a climatic chamber with three kinds of working posture on uneven($D_1-F_1$) or even($D_2-F_2$) ground surface. Tested work loads with three kinds of working posture were : moving in a sitting posture with attaching breast to legs and waving arms ($A_1$), moving in a bending posture with waving arms ($B_1$), and moving a 6kg weighting luggage in a standing posture ($C_1$) Physiological responses in the workers to three different work loads were observed in a climatic chamber, with or without using some instruments, to evaluate work efficiencies. The results obtained are summerized as follows. 1. $C_1$ was the hardest work and $B_1$ was harder than $A_1$ on the even ground. 2. Worker's physiological fatigue and physical loads remarkably decreased when using the instruments such as a chair and a cart with some rollers on the even ground. 3. Working with pushing a cart($F_1$) was the hardest work, and standing($D_1$) was harder than walking($E_1$) on the uneven ground. 4. Worker's physiological fatigues and physical loads remarkably decreased on the even ground. 5. Similar results were obtained when the same experiment was carried out in a plastic house.

The purpose of this paper was to review the problems relating to Korea's occupational health services and suggest ways to improve them. Korea can be classified as a welfare state type of conservative corporatism partially interwoven with liberalism. While experiencing compressed economic growth, the economic sectors of developed (excess areas) and developing (deficient areas) countries are interwoven. Therefore, it is necessary to perfect conservative corporatism along with a complementary reinforcement of liberal contents and to apply a multilayered approach focusing on complementing the deficient areas. It is essential to form a national representative indicator related to occupational health, and a strategy for selection and concentration is needed. The proposed central indicator is the occupational health coverage rate (OHCR), which is the number of workers who have applied for mandatory occupational health services under the Occupational Safety and Health Act in the numerator with the total working population in the denominator. This paper proposes ways to raise the OHCR, which is currently at the level of 25%-40%, to 70%-80%, which is the level of Japan, Germany, and France. To achieve this target, it is necessary to focus on small businesses and vulnerable workers. This is an area of market failure and requires the active input of community-oriented public resources. For access to larger workplaces, the marketability of services should be strengthened and personal intervention using digital health resources should be actively attempted. Taking a national perspective, work environment improvement committees with tripartite (labor, management, and government) participation for improvement of the working environment need to be established at the center and in the regions. Through this, prevention funds linked to industrial accident compensation and prevention could be used efficiently. A national chemical substance management system must be established to monitor the health of workers and the general public.

This study sought to measure the influence of HIMs' work environment changes on job stress, and to explore measures for improving job satisfaction among them. A total of 275 hospital HIMs' were surveyed using a structured questionnaire. Significant job stress impact variables were sorted out using a simple linear regression analysis. Then, through multiple linear regression analysis, multicollinearity was tested. Significant impact factors were identified from among the control variables, and job stress impact was measured. The survey revealed that in public hospitals where the EMR system has been implemented for a longer period, depression scores in HIMs' were increased. HIMs' job stress level was found to be affected by the following factors: computerization of their working environment, experience of depression, unemployment, and manpower reduction, as well as, their lifestyles, including leisure activities. The results of this study suggest that HIMs' job stress can be reduced through work environment improvement and improvement of their personal lifestyle habits.
