Background: Recently, irregular working hours have become controversial issues in Korea. The health impact of irregular working hours on the work-related musculoskeletal pain (MSP) is scarcely researched before. We sought to investigate the association between irregular working hours and work-related MSP among South Korean workers. Methods: This study used data from the sixth Korean Working Conditions Survey in 2020. The prevalence of work-related MSP was analyzed using the χ² test. A multiple logistic regression analysis was conducted to assess the association between irregular working hours and work-related MSP. We conducted stratified analysis by gender, weekly working hours, and workers' control over their working hours. We calculated the adjusted odds ratios (ORs) of work-related MSP for irregular working hours combined with weekly working hours. Results: The OR for work-related MSP was significantly higher in the population with irregular working hours than in the population with regular working hours (OR: 1.43, 95% confidence interval [CI]: 1.29-1.58). Irregular and long (> 52 hours/week) working hours have the highest risk of work-related MSP in both genders (in men, OR: 3.48 [95% CI: 2.53-4.78]; in women, OR: 2.41 [95% CI: 1.46-4.00]). Conclusions: Irregular working hours were associated with work-related MSP in Korea. The association was magnified with long working hours. Reform of the Korean Labor Standards Act leading to increase irregular working hours may induce adverse health outcome.

This study investigated the working conditions and job satisfaction of school cafeteria, according to their employment type in Chonbuk, South Korea. Self-administered questionnaires were collected from 401 elementary, middle, and high school cafeteria employees. The data showed significant differences between regular and irregular employees. These factors were: previous work experience (p<.001), type of school (p<.001), the style of foodservice at a school (p<.001), the type of foodservice system (p<.05), and the number of meals served each day (p<.001). The working conditions for regular and irregular employees were significantly different with regard to several factors: these were union membership (p<.01), how they were paid (p<.05), their total working hours (p<.01), and difficulty of using their holidays (p<.01). Approximately 80.5% of the subjects were dissatisfied with the working conditions after the introduction of countermeasures for irregular employees. Results indicated that the average employee job satisfaction level was 2.53, but that there were not significant difference in the level of job satisfaction when comparing regular and irregular employees. The item employees were most satisfied with was having responsibility over meals for young students (3.37). They were least satisfied with their salary (2.00). An interesting issue for future study would be to determine the factors that could improve job satisfaction whilst satisfying the employees' needs which in turn would improve the quality of foodservice.

Objectives: The Korean Working Conditions Survey(KWCS), which has been conducted five times over the past 13 years, presents a diverse picture of Korean workers across occupations, genders, and age groups. This study summarized the use of KWCS and explored how to make the most of the KWCS by reviewing published peer-reviewed journal articles employing the KWCS data. Methods: Articles were selected in accordance with PRISMA protocol for a systematic literature review. A total of 155 articles were included in this review. Results: The number of articles utilizing KWCS data has been increasing by year. The articles were published in 40 Korean journals and 16 international journals. The journals were mainly in the field of occupational safety and health and sociology. Keywords of mental health, working conditions survey, workforce, health, exposure to risk factor, and working time were mainly highlighted. The articles were grouped by the goals of the KWCS as stated in the survey. The majority of published articles(129 articles, 83%) aimed to 'analyze relationships between different aspects of working conditions'. Fifteen articles(10%) were intended to 'identify groups at risk and issues of concern.' The number of articles to 'monitor trends' were limited. Conclusions: The findings underline the limited utilization of the KWCS. Attention to the range and scope of utilization of KWCS should be developed to address current challenges in occupational health and safety management and policy issues.

The purpose of this study was conducted to determine the working conditions, post-traumatic stress syndrome and the self-resilience of nurses, and find out the relationship between the post-traumatic stress syndrome and the self-resilience. Data were collected by questionnaire method among 220 General Hospital nurses at Gyeongnam G and J city. Data were analyzed by using SPSS 21.0 program WIN. The results of working conditions of the nurses majority were shift work 70.5%, currently working in the ward 54.6%. Scores were shown as Post-traumatic stress syndrome (28.20) and self resilience (39.98). There is a negative correlation (r =.226, p=.001) between the post-traumatic stress syndrome and the self-resilience. Based on the result, since working conditions of nurses caused psychological stress and nurses with high self-resilience eased the degree of post-traumatic stress, in terms of the personnel management of hospitals, a psychological intervention strategy should be considered.

This study was planned to investigate the effect of the exposure to hazard factors on work environment satisfaction. Existing researches about job satisfaction have focused on the general working conditions, such as working hours, wage, human relationship, job task and so on. Korean Working Conditions Survey was used for this study because that relevant questions were included. The effect of the exposure to hazard factors on work environment satisfaction may be produced by hierarchical regression analysis because of comparison with existing model for work environment satisfaction. The exposure to hazards factors were statistically significant effect on work environment satisfaction after adjusting other confounding variables, such as gender, age, educational level, job security, work hour, work load, work autonomy, social support, etc. This study has some limitation because that KWCS was cross sectional survey. Some researches about the causal effect and its mechanism may be suggested as future study.

This study was performed to find out factors affecting degree of satisfaction with workers' working environment. The study subjects were 165 workers who were working at painting process of twelve furniture manufacturing factories in Incheon area. We used self-administered questionnaire containing general characteristics, working conditions, the degree of satisfaction with working environment, and the degree of satisfaction with working condition. In addition, we measured the exposure levels of occupational hazardous agents. The results were as follows; 1. Correlations between the degree of satisfaction with workers' working environment and the measured of occupational hazardous agents did not affect the degree of satisfaction with workers' working environment. 2. Factors affecting the degree of satisfaction with workers' working environment were not the exposure levels of occupational hazardous agents, but the degree of satisfaction with working condition, size of industry, health status, and types of ventilation system. As the degree of satisfaction with working condition was increased, the degree of satisfaction with working environment was increased. Also, for the workers who had good health status, the degree of satisfaction with work environment was appeared to be high. To increase the degree of satisfaction, with workers' working environment, firstly, effective work management and production control are required. Also, the worker's effort to negotiate continuously with top manager on improving working conditions is required. Secondly, developing heath promotion program to be appropriate for the characteristics of worksite is required. Moreover, leading worker's participation in health promotion program is very important to increase the degree of satisfaction with workers' working environment.

Currently frequency-dependent type electronic apex locators have been widely used to determine the working length in endodontic treatment. But, accuracy of electronic apex locators is controversial. The purpose of this study was to evaluate the accuracy of Root-ZX(Morita Co., Japan) at different kinds of conditions of root canals compared with the radiographic working length. The 40 extracted human anterior teeth with fully formed apices and without any caries were used. The radiographs were taken for working length with the 0.5mm short of #15 K-file tip just visible at the foramen under the surgical microscope(Carl Zeiss Co. Germany) at 25X. Then the electronic working lengths were determined with Root-ZX at the different kinds of conditions of root canals according to the presence of electrolyte and Crown-down pressureless technique. The results were as follows ; 1. There was no significant statistical difference in working length between radiograph and Root-ZX. 2. There was no significant statistical difference in electronic working length between the canal with electrolyte and without electrolyte. 3. There was no significant statistical difference in electronic working length between the canal without any instrumentation and after Crown-dow pressureless technique. 4. Of the total 40 root canals, 85% in Group I, 92.5% in Group II, 95% in Group III and 95% in Group IV using Root-ZX showed coincidence within 0.5mm accuracy compaing with the radiographic working length. The results showed that the Root-ZX can be use effectively for measuring the working length of root canal after instrumentation with Crown-down pressureless technique regardless of the presence of electrolyte in root canal.
