Proficiency-centered manufacturing environment of the past is now expanding into that focused on expertise and knowledge. So the paradigm shift about human resources and management of them is required to maintain competitiveness and run the organization in a stable way. Many studies have shown that in various fields job competence has a positive influence on job satisfaction, but researchers' point of view is limited only to proficiency. With a focus on this situation, this study has analyzed empirically the effect of job knowledge and proficiency on a turnover intention and its mediating effect of job satisfaction in S company whose manufacturing environment is changing fast. The analysis has shown that the job knowledge and proficiency have a positive effect on job satisfaction and that job satisfaction influences a turnover intention. It has an important meaning in that by estimating the relationship between employees' job knowledge and their turnover intention, this study is providing a basic data needed to manage job competence of manufacturing labor force.

This study aimed to examine the impact of workers' perceptions of the safety climate on job satisfaction and intention to turnover in the manufacturing industry. Data was collected from employees(n=143) working in the manufacturing industry. The perceived safety climate included perceptions of the safety commitment of the management, safety leadership of the immediate supervisor, and safety policy. Hierarchical regressions were conducted to identify the significance of the relation between the sub-variable of the perceived safety climate and job satisfaction, and intention to turnover. The results show that safety commitment and safety policy are significant predictors of job satisfaction. The immediate supervisor's safety leadership was significantly correlated with intention to turnover. These results indicated that the perceived safety climate of workers in the manufacturing industry might influence job satisfaction and intention to turnover. Therefore, organizations in the manufacturing industry should focus on improving safety climates to enhance job satisfaction and prevent employee turnover.

Purpose: This study was conducted to find out the effects of self-efficacy on job stress symptoms and coping strategies depending on perceived job stress. Method: The subjects were 447 workers employed in a manufacturing company. Demographic characteristics, self-efficacy, job stress, job stress symptoms and coping strategies were assessed by a self-administered questionnaire. Each envelope to keep the secret sealed completed questionnaires. Result: Job stress and job stress symptoms in workers with a high level of self-efficacy were lower than those of a low level of self-efficacy. Active coping strategies in workers with a high level of self-efficacy group were higher than those of a low level of self-efficacy. In multiple regression analysis, job stress symptoms were significantly higher in increasing job stress, increasing self-efficacy, office workers, manager group and increasing age. Active coping strategies were significantly higher in increasing self-efficacy, increasing career, males and decreasing job stress. Whereas passive coping strategies were significantly higher in females, increasing job stress and increasing self-efficacy. Conclusion: This study suggests that self-efficacy is a significant factor on job stress, job stress symptoms and coping strategies. Therefore, developing a job stress management program to increase self-efficacy and verifying its effects are needed.

Purpose: This study was conducted to investigate factors affecting the job embeddedness of workers in the manufacturing industry. Methods: The survey was conducted on 261 workers of the manufacturing industry in P city and Y city with the help of a structured self-report questionnaire, administered between June 10 and June 30, 2017. Data were analyzed using descriptive statistics, a t-test, ANOVA, a $Scheff{\acute{e}}s$ test, Pearson's correlation coefficients, and stepwise multiple regression. Results: There were significant differences in job embeddedness according to educational level, marital status, jobs and types of employment, satisfaction with salary, stress level, and the perceived health status of the subjects. There were significant positive correlations between role clarity of job demands (r=.45), leader member exchange (r=.48), recovery experience from job stress (r=.27), and job embeddedness. From the multiple regression analysis, the most significant factors affecting job embeddedness were found to be leader member exchange (${\beta}=.43$), recovery experience from job stress (${\beta}=.22$), and job demand (${\beta}=.15$). These variables explained 35.0% of the total variance in job embeddedness. Conclusion: In order to increase job embeddedness of workers in the manufacturing industry, it is necessary to prepare measures to increase job demand, leader member exchange, and recovery experience from job stress.

Manufacturing is fast entering a new age of industrial excellence that is being called "Agile Manufacturing." The goal of Agile Manufacturing is to link customers, suppliers, and the manufacturing system into a super-efficient confederation to produce a variety of products quickly and at a low cost. In order to improve the quality of the study of production input control(PIC) in a job shop manufacturing system by reducing the significant gap between research models and models of actual manufacturing systems, the previous line of research on PICs in a job shop manufacturing system is extended by integrating customers and suppliers with the manufacturing system. Then, a set of measures is developed to evaluate PICs, measures that reflect concerns of customers and suppliers as well as concerns of the manufacturer. Also, a weighted overall measure (with various cases to represent different possible weights of manufacturer's emphasis on the performance measures) is used to synthesize all the performance measures. Then, for each case, various existing PICs are evaluated in combination with various priority dispatching rules(PDRs).

Background: The purpose of this study is to investigate the relationship between job stress and impaired fasting glycemia (IFG) of male workers in a manufacturing industry. Methods: Data were collected from 5,886 male workers in a manufacturing industry who participated in the medical examination from June 19 to August 14, 2020 through self-reported questionnaires. The general characteristics of the subjects, shift work, high blood pressure, dyslipidemia, and job stress were included. Job stress was measured using the Korean Occupational Stress Scale (KOSS) consisting of 8 items and 43 questions. Multivariable logistic regression analysis was used to investigate the IFG association with job stress. Results: Among the various factors that can cause job stress, only high job demand was associated with a risk of IFG (odds ratio, 1.43; 95% confidence interval, 1.13-1.82) especially in non-shift worker. For all other factors, no statistically significant results were obtained. Conclusions: In this study of male workers engaged in the Korean steel manufacturing industry, the 'job demand' item among job stress of non-shift worker was related to IFG.
