Purpose This study aims to develop a work-related injury and illness monitoring geographic information system that analyzes and visualizes the types of work-related injury and illness based on workers' compensation insurance big data. Design/methodology/approach Using the developed system, we explained the process of monitoring the areas of the applied workplace, medical care application, index, and medical care institution. We also showed examples of analyzing the index and medical care institution area. By applying the system, we can intuitively recognize the current status of workers' compensation insurance and confirm the basic information necessary for managing the current status of workers' compensation insurance. Findings We generated more helpful information by combining workers' compensation insurance data and designated medical care institution data. We were able to apply the severity score and the vulnerability index of work-related injury and illness to the system as a demonstration. To efficiently manage workers' compensation insurance, it was necessary to integrate workers' compensation insurance and designated medical care institution data, as well as the data from various sources.

Background & Objectives: International radiation protection committee recognized the importance of radiation protection from medical practices because the exposure to the radiation in medical practice is higher than any other exposure. The factors on knowledge, attitude and practice of radiation safety of the medical workers engaged in radiation were analyzed in order to improve radiation safety technology. Method: Questionnaires were used for 1200 radiation workers in medical institution from July 23 through September 4 and collected for analysis. Results: Different level of safety measures were practiced by age, marital status, career, and medical facility. The difference was statistically significant. Higher levels of safety measures were practiced in the age group of 50s and married persons. The workers who have more than 20 years experience have higher level of safety measures. The workers of health centers have higher level of safety measures to compare with other workers. The factors which give more concerns on safety practice were self efficacy, practice and knowledge in order. Conclusion: Safety conscious operators should get additional education program to maintain higher level of safety. The operators who do not have much safety concern should be intensive training program for self efficacy and safety.

Background: Helicobacter pylori infection leads to many upper gastrointestinal diseases. Migrant workers are the main part of floating population in China. However, up to now, their health status has not been a focus of attention. Methods: In order to assess the status of H. pylori infection among migrant workers in Shijiazhuang, over five years we interviewed 324 individuals between 2007 and 2011. Each underwent a rapid urease test to identify H. pylori infection and socio-demographic indicators were collected using a survey questionnaire. Results: Our results showed that family income (P = 0.003), dietetic hygiene (P = 0.005), education (P = 0.004) and marital status (P = 0.007) were associated with H. pylori infection. Conclusion: We found that migrant workers had little basic knowledge of H. pylori and their prevalence of infection remains high. Therefore, we need to promote education and awareness of H. pylori and to ensure access to diagnosis and treatment for infected workers.

Background: As social distancing persists and interest in work-life balance grows, more companies are adopting flexible work policies. While there have been studies on sleep disorders associated with different types of work, such as shift work, research exploring the relationship between flexible work schedules and sleep disorders is still limited, particularly among Korean workers. Methods: We performed a secondary analysis of the 6th Korean Working Conditions Survey, focusing on 31,243 paid workers out of a total of 50,538 participants. We defined flexible workers as those who set their own working hours. Sleep disorders were divided into three categories: 'difficulty falling asleep,' 'frequent waking during sleep,' and 'waking up feeling exhausted and fatigued.' Using scores derived from three specific symptoms, the Minimal Insomnia Symptoms Scale (MISS) was calculated to assess the prevalence of insomnia. We used chi-square tests to analyze demographic and job-related differences. A multivariate logistic regression analysis was employed to identify any relationship between flexible work schedules and sleep disorders. Results: Significant differences were found between flexible and non-flexible workers regarding age, income level, education level, and job type. Flexible workers reported sleep-related symptoms significantly more often. The odds ratio for insomnia was 1.40 (95% CI 1.21-1.61). For males, the odds ratio was 1.68 (1.36-2.08). Conclusion: This study establishes a correlation between flexible work schedules and sleep disorders among Korean salaried workers. Potential causes could include changes in circadian rhythm, increased work demands, and extended working hours. To precisely determine causality and associated diseases, further research is required.

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.

The problem of excessive job burdens and high turnover rates in the social welfare area has been dealt with for a long time. However, there is a lack of discussions on the issue of voluntary turnover of medical social workers. The purpose of this study is to examine the effect of job demands on medical social workers' turnover intentions and to verify the mediating effect of job satisfaction on the relationship between job demands and turnover intentions. Among the medical social workers registered in the Korean Association of Medical Social Workers, 188 respondents currently working in hospitals were used for data analysis. As research methods, frequency, descriptive statistics, correlate analysis, and logistic regression analysis were conducted by SPSS 22.0 version and SPSS Macro Process v.2.16. Finally, bootstrap was conducted to verify the significant mediating effect of job satisfaction. The findings are follows: extrinsic job satisfaction was found to have the full mediating effect between job demands and turnover intentions of medical social workers. In other words, job demands of medical social workers affect turnover intentions through extrinsic job satisfaction, but there is no direct effect of the job demand on the turnover intention. On the other hand, intrinsic job satisfaction did not mediate the relationship between job demands and turnover intentions. Based on the results, we suggested organizational and institutional implications for improving the job demands affected to low job satisfaction and turnover intention of medical social workers.
