This paper investigates the employment and wage structural changes that have occurred around the economic crisis in 1997. We propose a theoretical model for external effects of human capital within firms and provide their estimation. When the employment and wage structural changes are considered simultaneously, labor demand decreases seem to more than offset labor supply changes during the period. While educational human capital, human capital accumulated with firm-tenure, human capital of married workers and of white-collar workers are considered to have positive external effects, human capital of relatively-old workers and managerial workers are considered to have negative external effects. We suggest that while employment restructuring with regard to age, tenure, and education and managerial workers during the period have improved the efficiency of firms, those with regard to married and white-collar workers have not.

Purpose: This study was conducted to investigate and analyze the association between stress from shift and non-shift work as well as the effects living habits have on eating habits in order to identify why and how workers can improve their health and form proper eating habits for higher working efficiency. Methods: The subjects of this study were 361 workers from K manufacturing company from April 7 to 11, 2014 and they were surveyed using a questionnaire. The subjects were divided into two groups according to working pattern: shift workers (n = 216) and non-shift workers (n = 110). Results: In the general characteristics, there were significant differences in age, work career, work time, marriage, monthly income, and education levels between the two groups. For healthy behaviors, significant differences in subjective health status, moderate physical activity, drinking, smoking, and sleep time were observed between shift workers and non-shift workers. For eating habits, scores of non-shift workers having a regular mealtime, balanced meal composition, and vegetable and seaweed intakes were significantly higher than those of shift workers. The sum score of dietary habits in non-shift workers was also significantly lower than that in shift workers (p < 0.05). Total job stress score did not significantly differ between the two groups. Conclusion: The sum of eating habit scores according to work types was $16.1{\pm}0.6$ in non-shift workers and $14.0{\pm}0.3$ in shift workers. These results suggest that it is necessary to provide food suitable to characteristics of different workers according to work type which should be provided along with daily nutrition counseling to help subjects recognize their status.

This study was performed to determine the effects on psychological and physiological variables of Horticulture Activity Caring Program for major company white-collar workers. Fifty three White-collar Workers participated in study. They were assigned to two groups (experimental group and control group) in random order. Random order is used Excel 2010 program RAND function of Microsoft. During the eight-week trial, the experimental group was treated with Horticulture Activity Caring Program weekly for 90 minute per session. The control group wasn't treated. Measurements of variables (stress, depression, blood glucose, total cholesterol, HDL-C, and LDL-C) were performed at weeks 0 and 8 for all participant. Changes in variables were calculated from baseline to trial completion. The data were collected from July to September 2014. SPSS 21.0 was used for the statistical analysis. : Horticulture Activity Caring Program had positive effects on depression (z=-4.57, p< .000). Conclusion of the study suggest the Horticulture Activity Caring Program may have positive effects on improving depression. We expect that the Horticulture Activity Caring Program will become a complementary and alternative therapy of mental health promotion for the white collar workers.

The study aims to evaluate job stress, self-efficacy, depression and health-related quality of life according to musculoskeletal symptoms of the ordinary white-collar worker. The subjects of the study were 83 workers who were working D Health Center and Dgu office of Gwangju Metropolitan City and they were voluntarily interviewed with a use of organized questionnaire. Except the responses from three subjects whose responses were insincere of 102 ones were decided for the final analysis. The results showed that there were significant differences in all job stress, self-efficacy, depression and health-related quality of life according to musculoskeletal symptoms. Depression, self-efficacy, job stress were significantly correlated; however, health related to quality of life was not. Therefore, as the results indicate that job stress, self-efficacy, depression and health-related quality of life can be affected by musculoskeletal pain for office workers, there is a need for the development of programs focused on the prevention of musculoskeletal discomfort.
