This present study tested whether job stress mediates the relationship between workload and safety behavior of members in organization. In addition, we hypothesized trust in leader/coworkers functions as moderator between not only the workload-job stress link, but also the job stress-safety behavior link. In order to investigate the hypotheses, 841 employees in various fields of companies were sampled. Using structural equation modeling(SEM), we conducted moderated mediation model analysis which elaborately investigated the significance of our hypotheses. The results indicated that job stress mediated the link between workload and safety behavior of members. In addition, the relationship between workload and job stress was moderated by trust in leader/coworkers. Moreover trust in leader/coworkers moderated the job stress-safety behavior linkage. The implications and limitations of our study and suggestions for future research were discussed.

This current research investigated whether job stress mediates the relationship between physical environment and safety behavior of members in organization. Furthermore, we hypothesized that safety climate functions as moderator between physical environment-job stress link. In order to examine the hypotheses, 870 employees in various fields of companies were sampled. Using structural equation modeling(SEM), we conducted moderated mediation model analysis which cab elaborately test the significance of our hypotheses. The results showed that job stress mediated the link between physical environment and safety behavior of members. Moreover, the relationship between physical environment and job stress was moderated by safety climate. The implications and limitations of our study and suggestions for future research were discussed.

The purpose of this study was to examine the level of job stress and depression, and to find the associated domains of job stress with depression among local public officials. The study subjects consist of 734 local public officials in Seogu, Gwang Ju. A structure self-reported questionnaire was composed of general and job-related characteristics, job stress(KOSS), and depression(CES-D). The use statistical methods were t-test, ANOVA, Pearson's correlation analysis and multiple logistic regression analysis. The total score of job stress was $44.38{\pm}7.96$ and the score of depression was $14.46{\pm}10.19$. The result of multiple logistic regression analysis was shown that the three domains of job stress including job demand, job insecurity and lack of reward were associated with the depression.
