The 52-hour workweek policy in Korea is a system that limits the maximum working hours per week to 52 hours including holiday work, which has been treated separately from overtime work during a week. Although this policy is designed to improve the quality of life and create jobs, it may also reduce the income of some workers. In general, it can be assumed that reduced working hours increase consumption at home. This study analyzed the effect of the 52-hour work policy on meat consumption patterns with the ordered logit model. Major factors considered in this study include working hours, income, and consumption frequency. It distinguished domestic and workplace consumption. The results show that the policy has had an impact on meat consumption patterns both at home and at work. If there is no change in income and only the working hours decrease, meat consumption in households increases. On the other hand, if both income and working hours decrease, household meat consumption decreases. Moreover, reduced working hours decrease the frequency of office happy hour and meat consumption in the workplace. However, the 52-hour workweek policy applies only to workers working more than 52 hours per week; thus, it is difficult to determine the overall effect of the policy on national meat consumption patterns.

Purpose: This study analyzed the relationship between working hours and the occurrence of industrial disasters based on manufacturing businesses that are members of Federation of Korean Trade Unions.Methods: Repliers were managers of the safety & health department in the union, and 215 surveys out of 300 businesses that agreed to participate in the research were analyzed. Results: 94 out of 300 companies, which counted for 43.7%, replied to have experienced industrial disasters. 56 of those (59.6%) had less than 52 working hours per week, and 38 companies (40.4%) had more than 52 working hours per week. 109 companies, which counted for 50.7%, did not have an incident of industrial disaster. Companies with an average of more than 52 hours of working hours per week were shown to have a 2.29 times (95% CI 1.08~4.87) higher possibility of having industrial disasters than those with less than 52 hours of working hours. Conclusion: As the study showed that industrial disasters were more likely to occur in businesses with working hours longer than 52 hours, ways to reduce working hours need to be developed and various safety measures need to be taken to prevent industrial disasters in case workers are undergoing long working hours.

These studies were conducted to: a) investigate work patterns and productivity indices, b) rate performance levels of employees and c) determine the suggested levels of personnel and labor hours for the effective labor control in school foodservice. Eighteen elementary school foodservices in Seoul were selected in order to analyze work patterns by the work sampling methodology. Allowance time and performance rating by VTR observation was done to determine the standardized labor hours. The results were as follows. The average percentage of each work function of the total work functions such as direct work function, indirect work function and delay were 65.57%, 8.12%, 26.31% respectively. The productivity index is 0.92 min/meal. The average working and delay hours per week of the foodservice director, foodservice employees and supply person were 33.64 hours, 23.25 hours, 38.52 hours respectively. The percentage of delay hours of total labor hours for foodservice employees and supply person were 42.27% and 24.0%. The standardized work hours and the appropriate levels of foodservice employees of 17 elementary school foodservices were examined: The average rating of the foodservice employees work was 1.19 and British Insulated Calendarer Cables (BICC) allowance rate was 19.40% on the average. The total work hours of foodservice employees were 172.64 hours per week and levels of personnel were 4.53 persons. BICC allowance rate was applied: The standardized work hours per week was 180.95 hours and appropriate levels of personnel were 4.11 persons based on legal 44 working hours.

Recently, As ICT technology develops, cyber attacks are becoming more intelligent and advanced. In order to cope with such cyber attacks, the security control system must be maintained 24 hours a day, 365 days a year. Security personnel should be able to respond in real time to cyber attacks through shift work for 24 hours, but the workforce law was revised in 2018 to affect manpower and security control work systems. Therefore, in this paper, we propose an effective security control work system by reducing 52 working hours per week.

This study was conducted to estimate the appropriate workforce of dietitians by type of kindergarten through the recognition survey and job analysis of the kindergarten. Nutritionists' duties were classified into 6 duties, 28 tasks and 94 task elements. The statistical data analysis was completed using Statistical Package for the Social Sciences (SPSS) (ver. 25.0). The time spent on 6 duties, including 'Nutrition management' (public attached 666.24 hours/year, public independent 843.04 hours/year), 'Foodservice management Practices' (public attached 1,472.52 hours/year, public independent 1,298.11 hours/year), 'Hygiene management of kindergarten foodservice' (public attached 611.78 hours/year, public independent 607.18 hours/year), 'Nutrition-diet education and counseling' (public attached 340.53 hours/year, public independent 253.42 hours/year), 'Managing snack during semesters and lunch/snacks during breaks' (public independent 309.04 hours/year) and 'Professionalism enhancement' (public attached 88.86 hours/year; public independent 65.17 hours/year). Total working hours for dietitians were 3,179.94 hours/year (public attached) and 3,375.97 hours/year (public independent). The time/day ×5 days/week ×52 weeks/year calculation method using derived total working hours/year was applied to derive appropriate full-time equivalents (FTEs). The analysis showed that the public attached kindergarten's FTEs were 1.53. The public independent's FTEs were 1.62, and the total FTEs were 1.55. This is the first study to analyze the workload of kindergarten dietitians and appropriate manpower by kindergarten establishment type. It is expected to be a valuable policy basis for efficient operation measures related to the kindergarten dietitians.

The purpose of this study was to investigate the acute (4 hours) and repeated-dose (6 hours a day, 5 days a week, 4 weeks) toxic effects of 1-hexene on Sprague-Dawley (SD) rats which were treated by inhalation. The results were as follows; 1. The median lethal concentration(LC$_{50}$) was estimated 52,694 ppm (confidence limit 95％; 49,494~55,447 ppm) in acute inhalation. Abnormal clinical signs related to the 1-Hexene were not observed with the acute inhalation dose. Cross findings of necropsy revealed on evidence of specific toxicity related to the 1-hexene. II. By repeated inhalation exposure the body weight of male were more or less reduced by the dose of 2,500 ppm and 5,000 ppm compared with control group. However there were no significant variation hematology and blood biochemistry for the exposed rats compared with the control rats. Abnormal clinical signs and gross findings of necropsy related to the 1-hexene were not shown. In conclusion when we exposed 1-hexene to SD rats for 4 weeks, 5 days per week, 6 hours per day, the Lowest observed effect level (LOEL) was over 2,500 ppm and Non observed effect level (NOEL) was below 500 ppm.

This study aimed to analyze time allocation for men who work long hours and their wives. Using 2014 time-use survey data (provided by Statistics Korea), we analyzed the amount of time spent in four areas-paid work, housework, leisure, and life essentials-of male workers who work more than 52 hours a week and of their wives. Descriptive statistics and a paired t-test were conducted using SPSS version 18.0. The results were as follows: First, the time allocation of men who worked long hours differed from their wives with the exception of personal maintenance time. Second, the working time of wives who work long hours was longer than their husbands who work long. Third, men who worked long hours did less housework when their wives were employed than when they were not employed. All the results showed gender differences in terms of time allocation. Equal role-sharing between spouses is needed for the work-life balance of both husbands and wives.

The purpose of this study is to compared the length of working hours and its effects on family life for Korean and Japanese full-time working couples. For this study, the survey used structured questionnaires and time diaries(one weekday and holiday), and the data were collected in the fall of 1995. A subsample of full-time working couples, 82 couples from Seoul and 79 couples from Tokyo, was used for the purpose of this study. The major findings are as follows; 1) On average, the weekday working hours of Korean husbands were longer than Japanese husbands(11 hours 31 minute, 10 hours 52 minutes a day, respectively). Wives in both countries worked almost identical lengths of time (9 hours 2 minutes in Korea and 8 hours 42 minutes in Japan). Working hours of husbands were longer than those of wives in both countries. Husbands' overtime. Almost (90%) of our Korea sample worked 6 days or 5 1/2 days per week, however the majority (69%) of our Japanese sample worked only 5 days per eek. 2) More Korean husbands and wives reported that their family life was constrained by wives working hours than their Japanese counterparts did. 3) All wives in both countries reported that the husbands long working hours has effects on quality family time. Korean wives perceived that their working hours had effects on time spent on child care, however Japanese wives perceived that their working hours affected their personal time and housework time. Korean husbands agreed with their wives working hours negatively affected their personal leisure time. Japanese husbands reported that their working hours negatively affected their sleeping time.

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.
