Objectives : To investigate the effect of overtime work on fatigue symptoms among Korean female workers. Methods : A total of 1,875 subjects were analyzed using the structured questionnaire, which was composed of overtime work, fatigue symptom, and background characteristics. Data analysis included multiple regression to test for a relationship of overtime work with fatigue symptom while statistically controlling for demographic and occupational variables. Results : Overtime work was more common in those with shorter work years of 3 or less than in those with longer work years. Overtime work was more popular in day workers than in shift workers. No significant difference of smoking and drinking state was observed between two groups. Subjective fatigue symptoms were significantly higher in overtime workers than in workers without overtime work. In a multiple regression analysis with significant control variables, overtime work was associated with 0.31 more fatigue symptom(p<0.001). Conclusion : Our findings suggest that overtime work may increase risks for fatigue symptom. Therefore, preventive strategies will be needed to control the negative effect of overtime work on health status of female workers.

Purpose: The aim of this study was to explore the relationship between nursing work environment and nursing outcome of clinical nurses. Also, the purpose of this study was to identify the nurses' workload. Method: The participants in this study were 246 nurses working at one hospital in a province. Data was collected using a structured questionnaire from October 2011 to November 2011. Open questions were subject to content analysis; closed questions were subject to descriptive statistics and Pearson correlation coefficient with SPSS 18.0 program were used. Result: The number of patients per nurse in day-duty and overtime work had a positive correlation. Nursing performance and the overtime work in night duty nurses had a negative correlation. The results of this study, with a much higher number of patients per nurse, showed an increase in overtime hours. In the nursing delivery system experience of nurses, 13 themes were identified and they were divided into five categories. Conclusion: Therefore, in order to improve nursing performance and increase job satisfaction, efforts must be made to reduce overtime, and nursing personnel placement to secure a substantial nursing staff.

Purpose: This study aimed to investigate the relationships between the characteristics of nurses' work schedules, health outcomes, and work-life balance. Methods: This was a secondary data analysis that included 422 nurses in Korean hospitals. Descriptive analysis, independent sample t-test, one-way ANOVA, Pearson correlation analysis, and multiple linear regression analysis were used to identify the associated factors. Results: Multiple linear regression analysis showed that work-life balance was lower when atypical work was performed (β=-.14, p=.010). Nurses who did not work overtime showed a higher level of work-life balance than those who worked overtime infrequently (β=-.11, p=.002) or frequently (β=-.28, p<.001). The work-life balance level increased when nurses had better subjective health status (β=.16, p<.001) or higher sleep quality (β=.29, p<.001). It was verified that the work-life balance level was higher for single-person households than for households with two (β=-.18, p=.003), three to four (β=-.16, p=.022), or five or more (β=-.21, p<.001) persons. Conclusion: This study suggests that government and hospital organizations should provide high-quality care and consideration to nurses who do atypical or overtime work as well as their subjective health status and sleep quality. Further research should focus on the development of a policy that improves the work-life balance of nurses, especially for those who work during atypical hours.

Low back pain patients and controls of shipyard workers were surveyed between June 1995 and September 1995 to identify risk factors of industrial low back pain. The patients were 17 male workers who had got medical treatment for over 3 days because of industrial back pain. Controls were 51 male workers who had not have musculoskeletal disorder for one year before the survey. By univariate analysis, the workers who did overtime work 4 times or more for the last 2 weeks showed odds ratio of 3.67 on low back pain with the workers who did less overtime work. Carrying heavy materials was also associated with the low back pain and the odds ratio increased with the increase of carrying weight. Work space and work posture were not associated with the low back pain significantly. The welder had higher odds ratio than the other workers on low back pain. The duration of employment and job satisfaction did not affect the risk of low back pain. Multiple logistic regression analysis showed that frequency of overtime work for the last 2 weeks and carrying heavy materials among the risk factors were associated significantly with the low back pain. We found that important risk factors of low back pain of shipyard workers are work intensity factors such as overtime work and carrying heavy weight.

The present Study investigated on effect of working time and physical work environment on job satisfaction, and is based on a representative survey carried out in the 15 European Union Member States in 2,000 on behalf of the European Foundation for the Improvement of Living and Working Conditions by Infratest Burke Sozialforschung and a consortium of national fieldwork institutes. In the course of the survey, a total of 21,703 people drawn from the economically active populations in the 15 countries were questioned about their working time, overtime, weekend work, physical work environment, social support of supervisor and co-worker and job satisfaction. Regression analysis and subgroup analysis were employed to examine the hypotheses. It was found that weekend work, overtime and physical work environment associate negatively with job satisfaction. Social support of supervisor and co-worker moderated only relation between working time and job satisfaction. The results provide support for prior quantitative studies partly. Based on these significant research findings, theoretical implications were discussed.

Construction labor productivity, which is the greatest source of variation in overall construction productivity, is the critical factor for determining the project performance in terms of time and cost, especially during scheduled overtime when extra time and cost are invested. The objective of this research is to select an appropriate type of probability distribution function representing the variability of daily labor productivity during overtime. Based on the results of statistical data analysis of labor performance during different weekly work hours, lognormal distribution is selected in order to take advantage of easiness of generating correlated random numbers. The selected lognormal distribution can be used for development of a simulation model in construction scheduling, cost analysis, and other applications areas where representation of the correlations between variables are essential.

Purpose: To analyze nurses' shift work according to the government guidelines for night work and their perceptions of their work schedules. Methods: The study sample included 487 nurses who provided information on their schedules, including the normal working hours of each shift, and overtime per shift during September 2020. Nurses' perceptions were measured in terms of satisfaction, appropriateness for work-life balance, and fairness to their work schedule. Results: One-third of the respondents worked more than 40 hours per week. The average overtime hour was 1.14 hours per shift. Unsocial hours (8 pm to 6 am on weekdays, midnight to midnight on weekends and public holidays) accounted for 56.4% of all working hours. During their last night shift, on average, nurses worked 9.62 hours and had a break of 39 minutes, although 20.5% reported no break. Sixty-eight percent of nurses had at least one between-shift break shorter than 48 hours after a consecutive night shifts. Fifty-seven percent were satisfied with their schedule. One-third perceived their schedule as appropriate for work-life balance, and two-thirds perceived that days off on weekends and nights were fairly distributed within the unit. Working and overtime hours had an inverse relationship with all three aspects of nurses' perceptions. A higher proportion of unsocial hours and having no breaks during the night shift were associated with lower perceptions of fairness. Conclusion: Reducing working hours, ensuring breaks during night shifts, and increasing rewards for unsocial hours are required to improve nurses' perceptions and reduce turnover due to shift work.

During a typical construction project, a contractor nay often find that the time originally available or normally expected to perform its work has been severely reduced. To finish the project by the completion date, the contractor is forced to find a way to speed up the progress of its work to compensate for the reduction in available time. The most frequent initial reaction of contractors to this situation is to increase on-site manpower by working longer time (overtime), adding more workers (overmanning), or implementing shift work (shift work) to increase the rate of progress. The goals of this study were to investigate how these three methods affect labor productivity and to quantify their impact on labor productivity by analyzing real project data collected from sheet metal contractors and mechanical contractors in the US.
