The purpose of this study is to draw employee support program at the company level through field survey of foreign laborers' satisfaction level of working life. To analyze the factors that determine working life satisfaction, regression analysis was conducted. Satisfaction level of working hours(t=2.469), living environment(t=2.140), post offices/banks (t=3.024) showed a statistically significant. Also these variables, working hours, living environment, post office/banks are verified to be very important for improving the level of their working life. Through these findings we can understand that employee support activities, providing user-guide of bank and post office, compliance with standards for working hours, improvement of the living conditions (accommodation, meals, etc.), the leisure time program support, the children care support and active utilization of foreign workers and strengthen the educational program, are necessary to improve the satisfaction level of foreign laborers' working life in Korea. It is recommended that managers need to recognize that careful consideration of living and working condition could contribute to stable settlement and increase working life satisfaction for the foreign workers at company level.

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.

Objective: A method to assess the risk level of agricultural works considering work posture and working time was suggested, and the method was applied to the major fruit crops. Background: It is not complete to analyze only work postures when assessing risk level of agricultural works. Method: $3{\times}3$ matrix was employed, in which the severity level was taken from the REBA method and exposure level was taken from the working time, using the criteria of caution zone/hazard zone. Results: Among the 5 major fruit crops(apple, pear, grape, peach, persimmon), the highest level of ergonomic risk was found in the apple and pear, while medium level was found in other 3 crops, mainly because the working time was less in the 3 crops. Conclusion: It was found that when assessing the overall ergonomic risk of agricultural works, work posture and working time should be considered at the same time. Application: The suggested method could be applied to other non-cyclic tasks.

The purpose of this study was to find out the 119 rescue and first aid's satisfaction level for their occupations, understand the influential factors of the satisfaction level and also analyze the level of each working districts. Therefore to provide basic information of policy decisions to increase the satisfaction level. Date were collected from 400 national the 119 rescue and first aids by questionnaire and using the tools, which has developed by Slavitt, from August 2 to September 30, 2002. The data were analyzed by percentage, mean t-test and ANOVA. Divided 39 items into 7 provinces to find out the satisfaction level of each province, follow as the influential factors of the satisfaction level. 1. The most of the 119 rescue and first aids were satisfying about their occupations as they got 3.02 marks out of 5, which is the full mark. 2. As the results after analyzed the relation ship between the satisfaction level and the general characteristics of analyzed the relation ship between the satisfaction level and the general characteristics of the 119 rescue and first aids, there were not statistically significant differences of sex distinction, age, scholarship, not married and has or have married, grade and qualification. There were statistically significant differences follow as working period, applying motive, moving, seeking a job, working place, an adviser, work overtime and compensation follow as work overtime. 3. It appeared that all the 119 rescue and first aids were satisfying enough about duty itself but were dissatisfying about working condition. As the results; job itself got 4.00, reciprocal action got 3.74, business demand got 3.28, autonomy got 3.06, organization demand got 2.96, pay got 2.43 and working condition got 1.72, each out of 5 full marks. As you see the results, most of the 119 rescue and first aids are satisfying about a job itself but they are dissatisfying about their working condition. Therefore we should formulate a plan that can increase the satisfaction level by improving duty system for 24 working hours per week.

The purpose of the high-speed railway construction is to better satisfy passenger travel demands. Accordingly, the design of the train working plan must also take a full account of the interests of passengers. Aiming at problems, such as the complex transport organization and different speed trains coexisting, combined with the existing research on the train working plan optimization model, the multiobjective bi-level programming model of the high-speed railway passenger train working plan was established. This model considers the interests of passengers as the center and also takes into account the interests of railway transport enterprises. Specifically, passenger travel cost and travel time minimizations are both considered as the objectives of upper-level programming, whereas railway enterprise profit maximization is regarded as the objective of the lower-level programming. The model solution algorithm based on genetic algorithm was proposed. Through an example analysis, the feasibility and rationality of the model and algorithm were proved.

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.

In this paper, we analyzed the relationship between employment stability, wage level, welfare system, working condition, job satisfaction and organizational commitment in order to find out ways to develop and competitiveness of the nano-convergence industries. Through this study, we conducted the possibility of deriving organizational commitment by job satisfaction which is given through employment stability, wage level, welfare system, and working condition for continuing their work life. In order to find relationships between each concepts, we used a multiple regression analysis with job satisfaction and commitment as dependent variable and employment stability, wage level, welfare system, and working condition as independent variables. Through this study, it was expected to increase the organizational commitment through the job satisfaction of the employees if a changing method of employees management is centered on some tasks suggested for the sound working condition and efficient utilization policies.
