Objective: The purpose of this study is to identify the kinds and exposure levels of health hazards in the metalworking process in relation to acute poisoning accidents caused by methanol in 2016. Methods: The number of industries, workplaces, exposed workers, regional distribution, and exposure level of health hazards in metalworking process were investigated based on employee exposure assessment database provided by KOSHA (the Korea Occupational Safety and Health Agency), which was collected from workplace hazard evaluation programs in Korea. Exposure metrics for methanol were assessed by RCR (risk characterization ratio). Results: The numbers of processes, workplaces, and exposed workers of metalworking, which include CNC (computer numerical control) were 25, 14,405, and 169,102 respectively. The numbers of samples of chemical hazards including methanol were 91,325, and it was found that workers in metalworking were exposed to 249 kinds of chemical hazards. There were 16 kinds of special controlled substances including beryllium. It is estimated that the number of workplaces involving CNC process was 2,537, and the number of exposed workers was 27,976. In CNC process, the total number of workplaces handling methanol was 36, and 298 workers were estimated to be exposed. There was no exceeded that surpassed the OEL and 49% of samples were below the limit of detection. Methanol exposure concentrations in Gyeonggido Province were statistically significantly higher than in other areas (p <0.0001). Conclusions: In the metalworking process including CNC, there is exposure to a wide variety of health hazards. There was no sample exceeding the OEL for methanol. Therefore, it is necessary to recognize the limits of the employee exposure assessment system and urgently improve measures to prevent the occurrence of events like methanol poisoning.

Objectives: This study was conducted to identify the characterization of organics solvent exposure among painting workers in the shipbuilding painting process, especially for their daily variations(within worker variance). Methods: Charcoal passive dosimeters were worn throughout each work shift for 20 days for five painting workers from October 19 to November 26, 2015. A total of 100 samples were collected, analyzed and compared with statutory workplace environmental measurements. Results: The geometric mean(GM) and geometric standard deviation(GSD) of mixed organic solvent(six substances) exposure index(EI) for the 100 samples were 0.42 and 4.42 respectively. The median and range of GSD for within worker EI representing five workers' daily EI variation is 3.72 and 2.63 ~ 5.20, respectively, which is classified as a very large variation(GSD>3). We were able to divide the painting process into two similar exposure groups(SEGs), Touch-up and Spray. Spray painting workers were much more exposed to organic solvent than Touch-up painting workers(GM=0.71 vs. 0.19), but less variably (GSD=3.64 vs. 4.10). xylene is the substance to which the workers were most exposed(GM=16.19 ppm, GSD=4.36), and the exposure characteristics of six substances including xylene is similar to those of EI. Conclusions: The daily variation of organic solvent exposure in the shipbuilding painting process is so high that statutory Assessment of Reliability of Work Environment Monitoring needs to be conducted with statistically sufficient number of samples and evidence.

The accident risk at the construction workplace associated with agricultural engineering is comparatively higher than those of other fields due mainly to its complex work types and processes. Agricultural engineering deals with a variety of agricultural infrastructures from irrigation and drainage facilities to giant-scale coastal reclamation land infrastructures. The characteristics that most agricultural projects have conducted on a small-scale even worsen the situation drawing low attentions to risk management. Therefore, systematical risk assessment that focuses on details of agricultural construction work process is required in order to enhance safety management capacity and to prevent repetitive accidents ultimately. This study aims to categorize construction work types and processes of agricultural construction works, and to quantitatively assess the accident risk of them based on accident analysis. Regarding classification of construction works, actual 827 accident cases were thoroughly reviewed and coded by their construction site, facility and work type, project scale and so on. Most accidents (71.8 % of total cases) occurred in small-scale construction workplaces with less than 5 billion Korean won project budget. And those accidents related to agricultural infrastructure project (37.4%) and agricultural water development project (22.4%). In terms of work types, accidents frequently took place in form-work followed by pipe installation work, steel bar work and concrete work. The potential risks were compared with actual outbreak of accidents based on Analytic Hierarchy Process (AHP). The results show that the potential conditions of accident expected to be took place is somewhat different from the actual conditions where accidents actually happened. This implicates that risk management manuals or education needs to be adjusted by reflecting unexpected circumstances. Overall, this study is meaningful in that the results could be foundations as to strengthen risk management capacity for agricultural engineering projects.

Purpose: The role of registered nurses is expanding in scope as the healthcare paradigm shifts from acute, hospital-based care to community and population-based care. Given this paradigm shift, this study explores the legal aspects of the role of a registered nurse. Methods: We used document analysis for extracting laws and legal orders related to nursing from the entirety of Korean law. Using textualism approach, we examined the contents utilizing a framework that was developed based on the role classification of community nurses by Clark in this study. Results: A total of 119 items related to nursing were derived from 64 laws. Of these, 71.4 % can be performed by people in multiple types of occupations including nurses. As a result of analyzing required qualifications, 45.4% of 119 items required additional qualifications besides registered nurse license. Analysis of workplace and activity type demonstrated that 26.1% of the 119 items were related to medical institutions, with nurses performing mostly "Client-oriented role." More than half (68.9%) were non-medical institutions, with nurses performing mostly "Delivery-oriented role." Some, however, did not stipulate the nurse's roles clearly. Conclusion: Therefore, to match the enhanced scope and responsibilities of registered nurses and to appropriately recognize, guide, and hold these nurses accountable, laws and policy must reflect these changes. In doing so, these updated laws and policies will ultimately serve as a basis for improving the quality and safety of nursing services.

The purpose of this study is to research support systems of the community child care services for optimum work-family balance. For this purpose, the questionnaire to be completed combined four areas: the workplace, school, community and home. Then questions concerning demographic factors and community-related aspects were analysed for this article. After analyzing 197 questionnaires, supplementary questions were asked, by interview to 10 samples. Full-time working wives (eg. working from 9am to 6pm) who have 1 or more children under 10 years old, living in Seoul and Gyeonggi province were collected as samples. The results were as follows: First, child care from family and relatives, and community services was properly used during the week, but dual working parents took complete charge of child care on Saturdays. Second, emergency child care was usually provided by the family, while relatives and community child care services were used less. Third, parents spent 17% of their monthly income on total child care expenditure. Fourth, community child care services were not used often, but the level of satisfaction with them was very high. Finally, they used relatives' services for safety reasons and community services for location, and only based on informed decisions. Therefore, Saturday child care programmes need to be initiated to help physically and mentally tired parents, with more general provision of positive and diverse public support systems.

Purpose: This study was performed to investigate the present condition of drug abuse and its association with depression, self-rated health and health behaviors by job status in Korean adults. Methods: Data were derived from the study on four addiction problem and suicide in 2014. Multiple logistic regression was used to analyze patterns of drug abuse according to depression, self-rated health and health behaviors. Results: The prevalence of drug abuse during the past year was 17.1% of the 4,018 subjects. About 3.3 times risk for drug abuse was found among individuals who had high depression scores. The risk of drug abuse was higher among those who were smoking (OR:1.46, 95% CI:1.17~1.83), drinking more frequently (OR:1.30, 95% CI:1.07~1.58), sleeping insufficiently (OR:1.31, 95% CI:1.03~1.67), eating irregularly (OR:1.45, 95% CI:1.19~1.76). Drug abuse problem was detected more seriously among employed than unemployed adults. Conclusion: Health-related behaviors, such as smoking, drinking, sleeping, eating should be considered simultaneously when designing strategies to deal with drug abuse problem, and it is important to understand the interaction between drug abuse and mental health. Furthermore, workplace based intervention can be effective in solving drug abuse problem.
