This study conducted two surveys to establish an educational system to prevent work-related musculoskeletal disorders. The first survey investigates the factors influencing the recognition of job specifications for risk factor analysts of work-related musculoskeletal disorders. The respondents of the first survey were selected from 173 different small-sized manufacturing enterprises having less than 300 workers and had experienced the inspection of risk factors. The results of the first survey shows that better recognition of job specifications are followed by the increase of education time, but regardless of the positions and periods of job experience. Among the respondents with a high level recognition, the second survey was conducted. According to the results, it is presented that 2, 8, 16 hours are the most suitable for educating workers, superintendents, and risk factors analysts. Based on the results of the second survey, educational contents have also been suggested. This research will provide the basic information when forming education systems to prevent musculoskeletal disorders.

Manufacturing environments in the real world are subject to many sources of change and uncertainty, such as new job releases, job cancellations, a chance in the processing time or start time of some operation. Thus, the realistic scheduling method should Properly reflect these dynamic environment. Based on the release times of jobs, JSSP (Job Shoe Scheduling Problem) can be classified as static and dynamic scheduling problem. In this research, we mainly consider the dynamic JSSP with continually arriving jobs. The goal of this research is to develop an efficient scheduling method based on GA (Genetic Algorithm) to address dynamic JSSP. we designed scheduling method based on SGA (Sing1e Genetic Algorithm) and PGA (Parallel Genetic Algorithm) The scheduling method based on GA is extended to address dynamic JSSP. Then, This algorithms are tested for scheduling and rescheduling in dynamic JSSP. The results is compared with dispatching rule. In comparison to dispatching rule, the GA approach produces better scheduling performance.

The purpose of this study is to investigate the overall levels of the middle-aged employed men's attitudes toward retirement and plans for post-retirement life, and to explore the relative effects of personal, family, and job characteristics on retirement attitude and the level of retirement plan. The data were collected from the 438 middle-aged (ranging from 41 to 50) employed men through the structured questionnaires. The data were analyzed using frequency, percentile, average, standard deviation, and multiple regression analysis. The results of the data analysis show that most of the respondents had neither positive nor negative attitude toward retirement and the level of planning for post-retirement life was slightly higher than average score on the scale. Next, the positive attitudes of middle-aged employed men toward retirement were observed from those who have higher education, larger household income, higher job security and lower job stress respondents who hold professional, administrative, or official jobs were more positive toward retirement than those who hold professional, administrative, or official jobs were more positive toward retirement than those who hold manufacturing or sales job. A well-planned post-retirement life was found among those who have better health, higher job satisfaction, job security and job orientation. Job characteristic variables such as job security and job satisfaction showed stronger impact than personal or family ones on the attitude toward retirement and the level of retirement planning. Household income and health also had significant effects.

This study examined the role of safety climate, organizational trust, job satisfaction, and organizational commitment. In addition, the study verified the mediating effect of organizational trust between safety climate, and job satisfaction and organizational commitment. Targeting population were the workers in the manufacturing sector. First, it was figured out that employees' recognition of organizations' safety climate has an effect positively on both job satisfaction and organizational commitment. Second, it turns out that individuals' safety awareness has a positive effect on the both job satisfaction and organizational commitment. Third, it was figured out that organizational trust plays a role as mediation when employees' recognition of organizations' safety climate has an effect positively on both job satisfaction and organizational commitment. Fourth, the result revealed that foreign investment company moderated the relationship between safety climate and organizational climate. Fifth, organizational trust mediates the relationship that the individuals' safety awareness are positively affected on the both job satisfaction and organizational commitment. Finally, The results of four hypotheses using intermediary variable in which organizational trust mediates the relationship between the safety climate and "work attitude" such as job satisfaction and organization commitment demonstrate significance of trust in organization in connecting safety climate and work attitude. Therefore, when trust in organization is enhanced, work attitude such as job satisfaction and organizational commitment could be improved.

Background: Studies on the association between occupational stress and depression have been frequently reported. However, the cross-sectional designs of studies limited insight into causal associations. In this study, we investigated the longitudinal association between occupational stress and new-onset depression among employees in a single manufacturing plant. Methods: The annual health checkup data of employees at a manufacturing plant in Korea were collected. A total of 1,837 male employees without depression who completed a health checkup during two consecutive years were included. Occupational stress was measured using a short form of the Korea Occupational Stress Scale (KOSS-SF), and depression was assessed using a Patient Health Questionnaire-2. The association between occupational stress change over the two years and newly developed depression was investigated using two logistic regression models. Results: Across all sub-factors of KOSS-SF, employees who reported increased occupational stress had a higher risk of new-onset depression. Newly developed depression was significantly associated with job demand (odds ratio [OR]: 4.34; 95% confidence interval [CI]: 2.37-7.96), job insecurity (OR: 3.21; 95% CI: 1.89-5.48), occupational climate (OR: 3.18; 95% CI: 1.91-5.31), lack of reward (OR: 2.28; 95% CI: 1.26-4.12), interpersonal conflict (OR: 2.14; 95% CI: 1.18-3.86), insufficient job control (OR: 1.93; 95% CI: 1.05-3.56), and the organizational system (OR: 1.84; 95% CI: 1.01-3.36). Conclusions: For every sub-factor of the KOSS-SF, occupational stress increase and persistent high stress were associated with the risk of developing new-onset depression. Among the seven sub-factors, job demand had the most significant effect. Our results show that occupational stress should be managed to promote employee mental healthcare.
