Purpose: The purpose of this study was to examine the level of occupational stress and depression in clinical nurses and to investigate the effects of subscales of occupational stress on depression. Method: A sample consisted of 202 nurses from 6 hospitals located in Busan and GyeongNam province. The data were collected from November 2008 to march 2009. A self-administered questionnaire was used to assess socio-demographics, job characteristics, depression measured by Korean CES-D, and occupational stress assessed by KOSS. Result: The total score of occupational stress in clinical nurses was within bottom 25%, but the scores of 'Difficult physical environment', 'High job demand', 'Inadequate social support', 'Organizational injustice' were within top 50%. The 8 subscales of occupational stress had significantly effects on clinical nurses' depression after controlling for age, marital status, type of hospital, current position. Conclusion: The administration of employee assistance program for management occupational stress is important for decreasing depression in clinical nurses.
Purpose: The purpose of this study is to identify visiting nurses' occupational satisfaction and their stress who are working at district health centers in Chungnam province. Methods: The subjects of the study were 109 visiting nurses of 16 district health centers in Chungnam province. The data were collected by self report questionnaires from March 1 to 31, 2010. The data were analyzed by Cronbach's ${\alpha}$, t-test, ANOVA (Sheffe's test), and correlation coefficient using the SPSS program. Results: The results of this study were as follows. The occupational stress level of the subjects was 46.7 and the level of subjects' occupational satisfaction was 2.46. There was a significant negative correlation between occupational satisfaction and occupational stress (r=-.627). Conclusion: The occupational stress level of the subjects, and stress levels of 'work environment', 'job insecurity' and 'organizational structure' were higher than those of the Korean women workers' standard. The level of subjects' occupational satisfaction was lower than that of the nurse practitioners. There was a significant correlation among occupational stress and 'burden of workload' and 'visiting nurse career'. The study showed that occupational stress was correlated with occupational satisfaction. The results suggest that further follow-up study on visiting nurse is necessary to relieve their occupational stress and increase occupational satisfaction.
Objective: The aim of this study was to propose revision of the occupational exposure limit(OEL) for 1-Bromopropane(1-BP) following a review of the appropriateness of the standard in light of increasing epidemiological data and handling risk. Materials and Methods: The results of toxicity and epidemiologic investigations for 1-BP and agencies' OELs were compared and reviewed through a literature review. In order to investigate the status of 1-BP handling in South Korea, data from work environment actual condition survey results and work environment measurement results were used. Results: The toxicity of 1-BP, such as central nervous system(CNS) damage, peripheral neuropathy, hematological adverse effects, and developmental and reproductive toxicity(male and female) has been reported. ACGIH recommends 0.1 ppm as a TLV-TWA value, but the OEL of South Korea stands at 25 ppm, which is 250 times higher than the TLV-TWA. Although 1-BP is a specially managed substance under the Industrial Safety and Health Law, the currently applied OEL cannot be said to be a safe level based on the results of epidemiological studies to date. In a work environment measurement in 2017, the total number of samples was 626, which were derived from 78 industries, and the average concentration was 1.173 ppm(standard deviation 2.88). Conclusions: To protect the health of workers handling 1-BP, estimated to be 780 in South Korea, it is necessary to strengthen the OEL(TWA) to a level of 0.3 ppm(lower than the 0.34 ppm with known toxic effects), which is believed to be safe as a result of epidemiological investigation. "Skin" notation should be recommended.
Purpose: This study aimed to identify the past and present status of occupational safety and health education in Korea and to explore future plans for these fields. Methods: We summarized past empirical or theoretical literature. Results: Occupational safety and health education strive to protect workers' health and create healthy workplaces by solving various problems such as workers' occupational diseases and mental health in the rapidly changing occupational environment. For occupational safety and health education to be effectively utilized in occupational sites, a live education that can be applied to the field should be provided. The need for education to explore and develop the ability to prepare for new hazards, including infectious diseases such as COVID-19, has increased. Conclusion: It is believed that the occupational health education element of the new era will be occupational health education. This focus will develop the ability to closely assess and predict the collective, organizational, and personal responses of affected workplaces and the impact of occupational health sciences.

Objectives: Small enterprises have higher exposure to occupational hazards compared to larger enterprises and further, they have fewer resources to control the risks. In order to improve the working environment, development of efficient measures is therefore a major challenge for regulators and other stakeholders. The aim of this paper is to develop a systematic model for the design of tailored intervention programmes meeting the needs of small enterprises. Methods: An important challenge for the design process is the transfer of knowledge from one context to another. The concept of realist analysis can provide insight into mechanisms by which intervention knowledge can be transferred from one context to another. We use this theoretical approach to develop a design model. Results: The model consist of five steps: 1) Defining occupational health and safety challenges of the target group, 2) selecting methods to improve the working environment, 3) developing theories about mechanisms which motivate the target group, 4) analysing the specific context of the target group for small enterprise programmes including owner-management role, social relations, and the perception of the working environment, and 5) designing the intervention based on the preceding steps. We demonstrate how the design model can be applied in practice by the development of an intervention programme for small enterprises in the construction industry. Conclusion: The model provides a useful tool for a systematic design process. The model makes it transparent for both researchers and practitioners as to how existing knowledge can be used in the design of new intervention programmes.
The study was conducted to analyze employees' and employers' awareness of occupational health programs for the purpose of evaluating the effectiveness of the program employed in small-scale enterprises (SSE). The 400 SSE that have under 50 employees and have been supported by the Government were selected for mail survey, and 120 employers and 318 employees of 183 factories returned the questionnaires. The results are as follows; 1) 33.8% of employees were not aware of the fact that their factories have been supported by Government, and 69.1% of employees did not know who was the monitor of that program. Only 147% of employees and 35.5% of employers agreed that the supported program reflected their opinions well. 2) 45.1% of employees participated in health education classes more than once. But only 15.6% of them considered the classes as very helpful. 21.1% of employers were much aware of health education schedule, and 44.2% reported that it was helpful for the prevention of occupational diseases. 3) 68.8% of employers were aware of the possibility of occupational diseases that could occur in their factories. And 36.5% of employers reported that some criteria were used for job reallocation to their employees. But only 9.7% of employees were assigned new job based on the result of health status examination. 4) 65.6% of employees were aware of the periodic evaluation for work environment, and 43.3% knew the evaluation results. Among participated SSE, 5.9% have a planning department for improving work environment, and 46.2% actually carried out the program for improving work environment. The findings showed that the employers and employees of SSE had insufficient knowledge of the occupational health program that have been employed in their workplace. It is essential to lead more active participation of employers and employees in their occupational health programs so as that the programs are to improve their health status as well as work environment more effectively.

This case report attempts to present a case of acute toxic hepatitis in fire extinguisher manufacturing workers exposed to 2,2-dichloro-1,1,1-trifluoro-ethane (HCFC-123) in August 2017 in Korea. Twenty-two-year-old male workers were exposed to HCFC-123 for 1.5 hours one day and for 2.5 hours the other day, after which one worker died, and the other recovered after treatment. The workers were diagnosed with acute toxicity of hepatitis. However, exposure levels of HCFC-123 were not known with no work environment measurement done. Therefore, this study was conducted to estimate the exposure concentration of HCFC-123 via a job simulation experiment. In the simulation, the HCFC-123 exposure concentration was measured with the same working practice and working time as with the workers aforementioned. As a result, the workers who infused HCFC-123 into storage tanks were estimated to be exposed to HCFC-123 at a concentration of $20.65{\pm}10.81ppm$, and a mean concentration of area samples within a working radius were estimated as $70.30{\pm}18.10ppm$. Valve assembly workers working on valves of a fire extinguisher filled with HCFC-123 were exposed to HCFC-123 at concentrations of $91.65{\pm}4.03ppm$ and $115.55{\pm}7.28ppm$, respectively, in the simulation, and area samples simulated within the working radius were also found to be high with concentrations of $122.75{\pm}91.15ppm$ and $126.80{\pm}60.25ppm$, respectively. Nitrogen gas packing workers, who did not handle HCFC-123 directly, were exposed to the agent at a concentration of $71.80{\pm}8.49ppm$. These results suggest that exposure to HCFC-123 at high concentrations for 1.5-2.5 hours caused acute toxic hepatitis in two workers.
Background: Occupational accidents occur for a variety of reasons, such as unsafe behaviors of workers and insufficient safety equipment at the workplace, but there are also various economic and social factors that can impact working conditions and working environment. This study analyzed the relationship between changes in economic factors and the occurrence of occupational accidents in Korea. Methods: Multilinear regression analysis was used as the analysis model. The general to specific method was also used, which consecutively removes statistically insignificant variables from a general model that includes dependent variables and lagged variables of dependent variables. Results: The frequency of occupational accidents was found to have a statistically significant relationship to economic indicators. The monthly number of cases of occupational injury and disease and fatal occupational injuries were found to be closely related to manufacturing capacity utilization, differences in the production index in the services sector, and commencements of building construction. The increase in equipment investment indicators was found to reduce fatal occupational injuries. Conclusion: The results of this study may be used to develop occupational accident trends or leading indicators, which in turn can be used by organizations that manage and monitor occupational accidents toward taking administrative action designed to reduce occupational accidents. The results also imply that short-term and mid- to long-term economic and social changes that can impact workers, workplaces and working conditions, and workplace organizations must be taken into account if more effective government policies are to be established and implemented toward further prevention of occupational accidents.

Background: The Functional Movement Screen (FMSTM) is a screening tool used to assess an individual's ability to perform fundamental movements that are necessary to do physically active tasks. The purpose of this study was to assess the ability of FMS to predict occupational injury among Denver Fire Department firefighters. Method: FMS tests were administered from 2012 to 2016. Claim status was defined as any claim occurrence vs. no claim and an overexertion vs. no claim/other claim within 1 year of the FMS. To assess associations between FMS score and claim status, FMS scores were dichotomized into ≤ 14 and > 14. Age-adjusted odds ratios were calculated using logistic regression. Sensitivities and specificities of FMS predicting claims at various FMS score cut points, ranging from 10 to 20 were tested. Results: Of 581 firefighters (mean ± SD, age 38 ± 9.8 y) who completed FMS between February 2015 and March 2018, 188 (32.4%) filed a WC claim in the study time frame. Seventy-two of those (38.3%) were categorized as overexertion claims. There was no association between FMS score and claim status [odds ratio (OR) = 1.27, 95% confidence interval (CI): 0.88 - 1.83] and overexertion claim vs. no claim/other claim (OR = 1.33, 95% CI: 0.81 - 2.21). There was no optimal cutoff for FMS in predicting a WC claim. Conclusions: Although the FMS has been predictive of injuries in other populations, among this sample of firefighters, it was not predictive of a future WC claim.
In concert with the development of new materials in the last decade, the need for toxicological studies of these materials has been increasing. These new materials include a group of rare earths (RE). The use of RE nanotechnology is being considered in some green applications, to increase their efficiency by using nano-sized RE compounds, and therefore hazard evaluation and risk assessment are highly recommended. This review was conducted through an extensive contemplation of the literatures in toxicology with in vitro and in vivo studies. Major aspects reviewed were the toxicological evaluations of these elements and metallic compounds at the molecular and cellular level, animal and human epidemiological studies and environmental and occupational health impacts on workers. We also discuss the future prospect of industries with appliances using RE together with the significance of preventive efforts for workers' health. To establish a safe and healthy working environment for RE industries, the use of biomarkers is increasing to provide sustainable measure, due to demand for information about the health risks from unfavorable exposures. Given the recent toxicological results on the exposure of cells, animals and workers to RE compounds, it is important to review the toxicological studies to improve the current understanding of the RE compounds in the field of occupational health. This will help to establish a sustainable, safe and healthy working environment for RE industries.
