The history of occupational health in Korea s covered the era of the Republic of Korea after the Liberation from the Japanese colonialism. But the number of Korean workers exceeded about 2 millions at the times of liberation in 1945, so that it is expected that many occupational health problems inflicted Korean workers under the Japanese colonialism. The authors reviewed medical literatures, administrative documents, and other available data which were published under the colonial state, and collected things which had reference to the health status of Korean workers. The results were as follows : 1. Nutritional status of Korean workers was supposed to be inferior to that of general population, some students, and poor inhabitants in a remote mountain villages. 2. It was supposed that the constitution of Korean workers was near lower limit of average build of contemporary Koreans. 3. The accidents rate in mines was significantly high but decreasing year after year, and the most important cause of accidents was the fall of roof in the mine. The medical facilities and equipments for miners were supposed to be not sufficient in the mines and workshops. 4. Some occupational disease including silicosis, noise-induced hearing impairment, and decompression disease were known. But, overall incidence or prevalence of these diseases could not be identified. 5. On the whole, the fatalities of acute infectious diseases of Korean workers were higher than those of Japanese inhabitants in Korea and Korean inhabitants. The prevalence of pulmonary tuberculosis of Korean workers was increasing with every passing year. 6. The medical personnels and facilities were so deficient that most Korean workers were out of adequate medical use. We discussed only a part of the health status of Korean workers under the Japanese colonialism, so it would be necessary to have a better grasp of details of occupational health policy and health status in the era of afflicting.

Objectives: The purpose of this study was to examine the relationship between the differences in employment status and self assessed health in Korea. Methods: We analyzed 4 year follow-up data generated by the Korean Labor and Income Panel Study(KLIPS), which was conducted on 1,207 men and 582 women who had undergone a change in employment status. The study subjects were placed into 1 of the following 4 groups based on their employment history; Non-precarious workers, Precarious to non-precarious workers, Non-precarious to precarious workers and Precarious workers. Logistic regression was then used to examine the relationship between the changes in employment status and self assessed health. Results: When males were considered, self assessed health was better among the precarious to non-precarious workers (OR 1.58, 95% CI=1.57-1.60) and the precarious workers (OR 1.29, 95% CI=1.28-1.30) than in the non-precarious workers, after adjusting for age, socioeconomic status (education level, occupational class, marital status, average equivalent household income and average number of hours worked per week), health behavior (smoking, drinking and exercise) and medical service access (regular medical examination, have chronic disease or hospitalized within 1 year). When female workers were considered, the precarious to non-precarious workers (OR 1.89, 95% CI=1.86-1.92), non-precarious to precarious workers(OR 1.24, 95% CI=1.23-1.26) and precarious workers (OR 1.27, 95% CI=1.25-1.28) all reported poorer health than the non-precarious workers after adjusting for the aforementioned factors. Conclusions: This study showed that changes in employment status were associated with differences in self assessed health among men and women. Specifically, the results of this study showed that a corresponding positive outcome based on self assessed health was greater for employees that changed from precarious to non-precarious jobs and for male employees with precarious jobs., whereas female employees with non-precarious jobs had higher self assessed health. However, additional longitudinal studies on the health effects of employment status should be conducted.

Korea has been rapidly industrialized during the past 35 years. During this period, Korea has emphasized only production and workers health has been ignored. Workers are most frequently exposed to organic vapors, such as thinners. This study was performed to evaluate worker exposures to organic solvents by size and type of industry. Results are summarized below. Workers were exposed to mixtures of toluene, xylenes, trichloroethylene, n-hexane, acetone, methanol, n-butanol, n-butyl acetate, and MIBK. Considering additive effects of the compounds, exposure indices (EIs) were calculated. It was found that worker exposures to organic solvents were highest in small industries and lowest in large industries. During a day shift, the highest exposure was indicated 3 - 5 p.m. in the afternoon. Workers in small industries had potential exposures exceeding permissible exposure limits for organic solvents. Local exhuast systems were inappropriate and respiratory protective devices were not supplied to the workers in small industries. Neither program for safe use and storage of toxic materials nor program for respirators was found in any of the plants investigated. Based on the results of the study, workers of small scale industries should be considered first in industrial health.

Background: The understanding of the relationship between risk perception, knowledge, and protective behaviors could play a major role in occupational risk control and management. Research exploring how workers perceive, recognize, and react to risks in different occupational settings is scarce in Thailand. The aim of this study was to assess the relationship of noise-related risk perceptions and knowledge to the use of hearing protective devices (HPDs) among sawmill workers in Thailand. Methods: Sawmill workers (n = 540) from four factories in Trang, Southern Thailand, participated in a questionnaire interview from December 2015 to January 2016. Descriptive statistics and linear regression models were used to explore the risk factors related to HPD use. Path diagram analysis was demonstrated and used to evaluate associations. Results: Risk perception was significantly correlated with HPD use (p < 0.01), HPD training (p = 0.01), and the number of years of work experience (p = 0.03). Sawmill workers were likely to use HPDs based on their risk perception and HPD training. However, HPD training was inversely correlated with age and the number of years of work experience. Conclusion: The study highlights the importance of risk perceptions and knowledge, and these factors should be emphasized in the design and implementation of any personal safety intervention program for sawmill workers.

Objectives: This study aims to evaluate the outcomes of an education program for public health service workers in public hospitals, utilizing the Kirkpatrick model. Methods: The study participants were 118 staff in 48 public hospitals. Of the stages in the Kirkpatrick model(reaction, learning, behavior, and result), reaction and learning stages were analyzed in this study. A 10-item self-evaluation questionnaire was used to measure satisfaction level for the reaction, and achievement of learning purposes for the learning. The education program consisted of general courses and special two tract courses(Tract A: chronic diseases, Tract B: health promotion). Results: The highest score for reaction was for Tract A(score=4.4), whilst the lowest score for reaction was for lecture(score=3.0). Learning achievement was significantly different between pre-education and post-education(p<0.01), except for health technicians. Conclusions: The results of this study could be utilized to develop effective systematic education programs for public health service workers in public hospitals.

Purpose: The purpose of this descriptive, cross-sectional study was to examine relationships among emotional labor, self-efficacy, and burnout of employees in public health centers. Factors that influence burnout of workers were also assessed. Methods: One hundred sixty six workers in public health centers completed a pack of self-report questionnaires. Collected data were analyzed using descriptive statistics, t-test, one-way ANOVA along with $Scheff{\acute{e}}$ test, and stepwise multiple regression. Results: Employees in public health centers seemed to experience emotional labor to some extent. There were statistically significant differences in burnout depending on the age of workers. Employees' burnout had a positive relationship with emotional labor and a negative relationship with self-efficacy. Factors influencing burnout of employees in public health centers were emotional dissonance, surveillance & monitoring of organization, age, and self-efficacy. Conclusion: Considering the findings from this study, health care providers need to develop effective interventions which increase the level of self-efficacy and decrease certain types of emotional labor for employees in public health centers and to help them effectively manage burnout.

Background: As health care workers face a wide range of psychosocial stressors, they are at a high risk of developing burnout syndrome, which in turn may affect hospital outcomes such as the quality and safety of provided care. The purpose of the present study was to investigate the moderating effect of job control on the relationship between workload and burnout. Methods: A total of 352 hospital workers from five Italian public hospitals completed a self-administered questionnaire that was used to measure exhaustion, cynicism, job control, and workload. Data were collected in 2013. Results: In contrast to previous studies, the results of this study supported the moderation effect of job control on the relationship between workload and exhaustion. Furthermore, the results found support for the sequential link from exhaustion to cynicism. Conclusion: This study showed the importance for hospital managers to carry out management practices that promote job control and provide employees with job resources, in order to reduce the burnout risk.

In Korea, female workforce has reached more than 40% of total working population, but the effects of work on spontaneous abortion are yet to be examined. This study as conducted to investigate the occupational effects on spontaneous abortion. Medical insurance claim data were used to examine the effects of the employment status and industry of employment on spontaneous abortion. The study population was composed of females, aged $15{\sim}44$, who were the beneficiary of medical insurance in the month of June, 1993. The working females covered by medical insurance for industrial workers, had the highest age-adjusted Spontaneous Abortion rate (SAB rate=claim frequency of spontaneous abortion/claim frequency of complication of pregnancy, childbirth and the puerperium), 6.65% whereas female dependants of medical insurance for industrial workers had the lowest age-adjusted SAB rate, 4.54%. Among industrial workers, the workers in manufacturing industry had the highest age-adjusted Spontaneous Abortion ratio(SAB ratio=claim frequency of spontaneous abortion/claim frequency of completly normal delivery), 43.2/100 whereas those in financing and service industry had age-adjusted SAB ratio, 16.2/100 and 20.5/100, respectively. The results of the study suggest the adverse effect of manufacturing Industry on reproduction. Work environments such as chemical exposures, overwork, awkard posture, and job stress should be further studied for their effects on reproductive functions of female.
