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.

The objective of this study was to identify risk factors associated with the occurrence of musculo-skeletal symptoms of cashiers and provide suggestions for an improved workspace design. Workload and exertion of each task were measured using job analysis and posture analysis. The three most time-consuming tasks were waiting (43.8%), scanning (23.5%) and payment transaction (22.9%). It was analyzed that the workspace can be improved by applying Korean anthropometric data to the design of the desk height. The most common posture was a standing posture with neutral back, and bent lower arms and hands. Finally, it was revealed that ``scanning`` and ``payment transaction`` seemed more stressful than other operations. The result of the ergonomic evaluation would be a useful basis for designing an improved workspace.

The goal of this study was to determine whether food industry workers are exposed to musculoskeletal loads due to the work time, frequency, awkward postures and inappropriate workspace design. Three catering workers were evaluated based on job analysis and posture analysis. The results showed that the four most time-consuming tasks were arranging(17%), cooking(16%), handling before cooking(15%) and cutting(15%), and the four most frequent tasks were arranging(21%), cooking(18%), handling after cooking(16%) and handling before cooking(13%). The most common posture was a standing posture(73%) with neutral back(73%), and bent head(50%), left lower arm(71%), right lower arm(78%) and right hand(60%). The comparative analysis of subtasks for the risk levels of musculoskeletal disorders was conducted using the work time, frequency and cumulative time of the postures. The ``displaying`` and ``handling after cooking`` showed higher risk levels than other subtasks. In addition, the height and length of the tables were evaluated to be inadequate for the workers. It can be concluded that the working environments for catering workers of restaurants should be improved due to the high cumulative time of awkward postures of upper extremities.
