Objective : The purpose of this study was to verify the differences of expressed character strengths graded as per the Korean Strength Scale, based on the type of work. Methods : A total of 2,444 conglomerate workers were classified into two groups: 1,356 office workers and 1,088 production workers. The subjects were examined through a web or mobile application based on the Korean Strength Scale. The Korean Strength Scale consists of a total of four top entries and 25 sub-items with appropriate validity. Results : The difference in the average score of sum of character strengths between the two groups was not significant. In the office worker group, character strengths such as love of learning, creativity, perspective, curiosity, facilitation, judgment and faith had significantly high scores. On the other hands, modesty, hope, gratitude, sincerity, magnanimity and self-regulation were high in the production worker group. The results remained unchanged in additional analysis of covariants as sex, age and education level, except for self-regulation and faith. Conclusion : Our results suggest significant differences in the character strengths between the two types of work; however, the average of sum of character strength score remains unchanged. These results may help to understand differences between work environments and thus help to establish a positive foundation.

Blood toluene concentrations of thirty nine Korean toluene-exposed workers in shoes making factory were checked by headspace-gas chromatographic analysis. Air toluene concentrations in each worker's working region also checked by personal sampler during workshift and analyzed by gas chromatography. The range of blood toluene concentration was 0.15-0.84mg/L. The range of toluene concentration of each worker's working area was 8.46-189.9ppm. The correlation between blood and air concentration of toluene was 0.824.

노인인구의 증가에 따라 사회보험제도가 출현하였고 이에 한국과 일본 양국에서는 전문적인 요양보호사와 개호복지사의 양성이 중요한 이슈로 이야기되었다. 본 연구의 목적은 한국과 일본의 케어워커에 대한 제도인식과 직무만족도를 비교연구 한 것이다. 연구대상으로 한국은 요양시설과 재가시설에서 근무하는 경남지역 요양보호사, 일본은 양로시설과 특별양로홈에서 근무하는 오사카지역의 개호복지사로 2009년 12월 20일에서 2010년 1월 5일까지 각각 150부씩 총 300부 설문조사하였다. 본 연구의 결과는 보험제도에 관한 인식은 낮은 편이고 반면 직무만족도는 높게 나타난 편이다. 하지만 업무스트레스는 상당히 높은 것으로 조사되었다. 또한 직무만족도와 직무스트레스는 한국과 일본 케어워커가 유의미한 차이를 보였으며, 다만 직무만족도와 직무스트레스에 개인의 특성과 업무특성에 따라 의미 있게 나타지 않았다.

Objectives: The major objective of this study was to develop a tier 2 exposure model combining tier 1 exposure model estimates and worker monitoring data and suggesting narrower exposure ranges than tier 1 results. Methods: Bayesian statistics were used to develop a tier 2 exposure model as was done for the European Union (EU) tier 2 exposure models, for example Advanced REACH Tools (ART) and Stoffenmanager. Bayesian statistics required a prior and data to calculate the posterior results. In this model, tier 1 estimated serving as a prior and worker exposure monitoring data at the worksite of interest were entered as data. The calculation of Bayesian statistics requires integration over a range, which were performed using a Riemann sum algorithm. From the calculated exposure estimates, 95% range was extracted. These algorithm have been realized on Excel spreadsheet for convenience and easy access. Some fail-proof features such as locking the spreadsheet were added in order to prevent errors or miscalculations derived from careless usage of the file. Results: The tier 2 exposure model was successfully built on a separate Excel spreadsheet in the same file containing tier 1 exposure model. To utilize the model, exposure range needs to be estimated from tier 1 model and worker monitoring data, at least one input are required. Conclusions: The developed tier 2 exposure model can help industrial hygienists obtain a narrow range of worker exposure level to a chemical by reflecting a certain set of job characteristics.

Purpose : The purpose of this study was to investigate the difference in gender related to health status, occupational environment, occupational safety and health and hazardous chemicals use of migrant workers in Korea. Method: The survey was conducted in clinics that provided free healthcare services for migrant workers. Of the 413 respondents, 66.3% were males and 33.7% were females. Result: In the case of male migrant workers, many worker were not fluent in Korean, had illegal status in the country, and had moved jobs frequently. There were many cases in which migrant workers worked in small-scale enterprises and worked long hours. Job stress score was high for many workers and they dealt with heavy materials and risky machines. Many workers had not received proper occupational health and safety education and those that were previously injured had repeated injuries. Among the female migrant workers, many worker received low salary and shift work was common. Many worker complained of gastrointestinal and musculoskeletal illnesses and treated toxic substances. Conclusion: As a result, it will be necessary to focus on the strategies for decreasing occupational injuries from physical risk factors for males and from chemical risk factors for female migrant workers.

Purpose: This study was conducted to analyze the characteristics of work-related musculoskeletal diseases (MSD) and the factors for approving MSD by the parts of the body. Methods: The analysis was done using the data which were drawn from the Industrial Accident Compensation Insurance that is operated by the Korea Worker's Compensation & Welfare Service. The data were composed of total cases related to the work-related diseases from 2006 to 2009. In addition, MSD data input by an investigator were collected. The factors associated with MSD were analyzed using ${\times}2$ and multiple logistic regression. Results: MSD approved cases have increased since 2006 and the proportion of the approved work-related MSD cases in the workers with work-related diseases in 2009 were 33.4%. Spinal approved cases were the highest percentage and upper and lower extremities cases gradually increased. The factors for approving upper extremity were found to be age, company size, type of industry, working duration, and in the case of spine to be company size and heavy lifting. Conclusion: Work-related MSD have increased and the factors that affected MSD by the parts of the body varied. Management strategy must be established to prevent MSD by the parts of the body.

Background: Although many studies have been conducted on worker fatigue and sickness absence, the association between fatigue and sickness absence is unclear in Korean workers. This study was conducted to investigate the effect of worker fatigue on future sickness absence. Methods: The study was conducted on workers who received medical check-ups at a university hospital for two consecutive years (2014-2015). During check-ups in the first year, the Fatigue Severity Scale (FSS) was used to assess fatigue levels, and during check-ups in the second year, sickness absence was surveyed to determine whether they had been absent from work due to physical or mental illness during previous 12 months. The χ² test was used to analyze relationships between sociodemographic and occupational characteristics, fatigue levels, and sickness absence. Odds ratios (ORs) were calculated by logistic regression analysis controlled for confounding factors. Results: A total of 12,250 workers were included in the study, and 396 (3.2%) workers experienced more than one day of sickness absence during the study period. Adjusted ORs for sickness absence were 3.35 (95% confidence interval [CI]: 2.64-4.28) in the moderate-fatigue group and 6.87 (95% CI: 4.93-9.57) in the high-fatigue group versus the low-fatigue group. For men in the moderate- and high-fatigue groups, adjusted ORs for sickness absence were 3.40 (95% CI: 2.58-4.48) and 8.94 (95% CI: 6.12-13.07), and for women in the moderate- and high-fatigue groups, adjusted ORs for sickness absence were 2.93 (95% CI: 1.68-5.10) and 3.71 (95% CI: 1.84-7.49), respectively. Conclusions: Worker fatigue is associated with sickness absence during the following 12 months, and this association appears to be stronger for men than women. These results support the notion that sickness absence can be reduced by evaluating and managing work-related fatigue.
