Recently Korea is expected with the decrease of population in working ages and also population structure, especially age structure, has changed as aging goes faster. This study focuses on the relationship between age structure and wage structure to analyzes the cohort size effect on the change of age-earnings profile. Our empirical analysis based on Wright(1991)'s model takes weighted OLS regression using the male worker's data of Ministry of Labor 'Wage Structure Survey'($1990{\sim}2006$). In pooled data, we take the conclusion that the cohort size effect was found in high school and college graduate workers, but the effect is different between them. The labor market entry effect of high school graduate workers is negative(-) and his persistent effect is positive(+). On the other hand, the cohort size effect of college graduate workers have appeared the opposite directions in contrary with the existing results of Welch(1979) and Wright(1991). This results are seen as the possibility that college graduate worker has the benefit of wage level by his relative cohort size in spite of high unemployment of young graduate. It will be the sign of need that we should interest in the change of age structure with balancing the labor supply side approach and the demand side study which the previous studies was mainly tended to focus on.

The purpose for this study was to investigate the health status according to the age and BMI by interviewing male workers in their twenties and thirties in the Daegu Gyeongbuk region. The body measurement was assessed by height, weight, BMI, body circumference (waist, hip), waist-hip ratio and body fat mass. The health status has been analyzed and assessed as normal group, health concerned group and health suspected groups. Weight, percent ideal body weight (PIBW), BMI and body circumference (waist, hip) and waist-hip ratio was proven higher according to the order of obese group, overweight group and normal group. Waist-hip ratio was proved to be higher in the thirties group than the twenties. Body fat mass was higher in the obese, overweight and normal groups. In the concerns of health status, the ratio of health concerned group and health suspected group increased according to the increase of BMI. Blood pressure (SBP, DBP) was higher in the obese group than in the normal group and overweight groups, and blood glucose was higher in the thirties than in the twenties. SGOT, SGPT, ${\gamma}-GTP$ has been proven higher in the obese group than in the normal group and overweight group, ${\gamma}-GTP$ was higher in the thirties than in the twenties. Investigating the correlation of the anthropometric characteristics and biochemical characteristics, the heavy weight resulted in heavier BMI, PIBW, body circumference (waist, hip), waist-hip ratio and higher body fat mass. Blood pressure (SBP, DBP), total cholesterol, blood glucose, SGOT, SGPT and ${\gamma}-GTP$ all became higher according to these influences. In conclusion, male workers have to recognize that health status becomes worse and possibilities of chronic disease prevalence rate increases according to aging and the increase of BMI. Accordingly, it is necessary to make an effort to prevent chronic diseases.

Purpose: The purpose of this study was to identify quality of sleep and its influencing factor among middle-aged male workers. Methods: The subjects of this study were 411 middle-aged male workers living in Seoul and Gyeonggi-do. The data were based from self-reported using structured questionnaires asking about low urinary tract symptoms, circadian rhythm, quality of life and sleep quality including general characteristics. The data were collected from September 11 to October 31, 2013 and analyzed by t-test, one-way ANOVA, Pearson correlation coefficient and hierarchical regression. Results: Mean score of the sleep quality was $5.03{\pm}2.57$ (range: 0~21) and reported as bad sleep quality in 55.7%. Low urinary tract symptoms (${\beta}$=.30, p<.001), circadian rhythm (${\beta}$=-.17, p<.001), quality of life (${\beta}$=-.14, p<.001) were shown as significant association of sleep quality. Conclusion: Strategies to improve sleep quality in middle-aged male workers are necessary and nursing intervention should be developed to improve education program for prevention and management of low urinary tract symptoms. It is also necessary to legalize the institutional devices to upgrade work environment and to place regulations on overtime at work places in order for these workers to obtain sufficient sleep time for recovery of biological rhythms and improving sleep quality.

This study was performed to determine the depression and its association with sleep quality, occupational stress and fatigue among small-scale manufacturing male workers. The self-administered questionnaires were given to 856 workers under 50 members of manufacturing industries during the period from April 1st to June 30th, 2010. As a results, the distribution of depression group(21 point and over at CES-D score) among all subjects were 44.3%, and it was positively correlated with occupational stress, fatigue and quality of sleep. With the analysis of covariance structure, occupational stress(KOSS) was more influential on the depression than quality of sleep and fatigue. It was found to have the inter-relational effects that the higher the occupational stress(KOSS) and fatigue(MFS), and the lower the quality of sleep, the higher the depression. Thus the effective strategy for depression reduction among workers requires the efforts to improve the work environment and job contents.

This paper examines the role of adverse working environments in the determination of workers' compensation in South Korean. I use the Third Korean Working Conditions Survey(2011), Occupational Safety and Health Research Institute that provide relevant variables in objective and subjective compensation and workers of diverse working environment. I find that risk factors in adverse working environments have a very minor role in the determination of individual wages. In contrast, adverse working environments have significant relationship with the level of compensation satisfaction. In addition, the results show that workers are more likely to receive compensation from psychological risk than physical risk. And women receive much more compensation in the psychological risk. These results provide useful information for improvement of working environments.

Compared to other manufacturing industries, the food manufacturing industry has a relatively large number of women casualties compared to men, and the number is steadily increasing. The age of casualties is also increasing as the society enters into an aging society. This is also evident in the food manufacturing sector. Therefore, this study conducted a survey on the safety and health awareness of workers by age and gender at small workplaces in the food manufacturing industry. Among them, we would like to focus on elderly women workers and analyze their accident characteristics to suggest ways to reduce the accident rate.
