Objectives: The purpose of this study was to investigate whether chemical exposure among workers has relevance to dyspnea using data from the $3^{rd}$ Korea Working Conditions Survey. Methods: The research subjects were 29,711 wage workers. Chemical exposures consist of four factors, (1) breathing in vapors, fumes, dust and dirt, (2) breathing in organic solvent vapors, (3) handling or touching chemicals, and (4) secondhand smoke. Multiple logistic regression analysis was performed to examine the association between chemical exposure and dyspnea in the last 12months using proc surveylogistic in SAS 9.3 statistical software excluding people who had received a diagnosis of hypertension or obesity that can affect the respiratory distress symptoms(n=27,842). Results: Chemical exposure among workers was associated with dyspnea after adjustment for demographics and job characteristics. Prevalence of dyspnea was 4.9 per 1,000 among men and 5.8 per 1,000. Compared to a total score of 0 points of chemical exposure among workers, a total score of 1, 2-3, and 4 points tended to have increased risk of dyspnea in a dose-response manner for both men (OR=1.43, 1.93, and 4.26; P-for trend=0.002) and women(OR=1.10, 2.81, and 7.70; P-for trend=0.002). Stratified analysis by duration of current job showed that the association between chemical exposure and dyspnea tended to get stronger until 15 years and then disappeared afterwards, which reflects healthy worker survivor effect. Conclusions: We observed significant association between chemical exposure and dyspnea using the data of the $3^{rd}$ Korea Working Conditions Survey. Our results warrants providing knowledge related to chemical exposure, performing prevention activities, and creating various health policies to protect workers.

This study is a descriptive correlation study to identify the factors affecting life satisfaction for shift service workers and is a secondary data analysis study using the raw data from the Fifth Korean Work Environment Survey. Five hundred and seventy-seven study subjects were selected from 20-year-old wage workers who had more than one year of work experience at the time of the survey and had worked more than 40 hours a week. The analysis used SPSS 23.0 WIN, including a t-test, one-way ANOVA by Scheffe test, Pearson's correlation oefficients, and Hierarchical multiple regression analysis. Regarding the general characteristics of the subjects, there was a difference in life satisfaction according to age, educational level, industrial type, and subjective health status. The higher the work-life balance and work satisfaction of the shift service worker, the higher the life satisfaction. In addition, social support had a moderating effect on the relationship between work-life balance and work satisfaction of shift service workers. Active social support, work satisfaction, and work-life balance improvement promotion programs were developed and applied to shift work service workers considering the factors influencing life satisfaction, thereby improving the life satisfaction of work shift service workers.

The aim of this study is to explore the factors that influence the health care utilization of disabled workers who returned to their original workplace after an occupational accident. The study sample consisted of 457 workers who suffered from occupational accidents and were rated as disabled based on the data from the PSWCI in 2021. Data analysis was performed using a hierarchical multiple regression analysis with SPSS WIN 26.0. The study findings revealed that the number of outpatient visits was affected by factors such as daily wage payment, economic status, physical activity limitations, subjective health status, and chronic diseases. Moreover, health care expenditures were determined by factors such as having a caregiver for daily living, burn injuries, and physical activity limitations. Therefore, to increase the accessibility of health care utilization for disabled workers, the role of nurses in the workplace should be expanded, employers should include a health care utilization plan when developing a return-to-work plan, and research on the introduction of a paid sick leave system that allows workers to rest when they are sick is needed. It is also necessary to alleviate the economic burden by increasing the coverage of benefits for burn and rehabilitation treatments.

One of the key features of the Korean labor market is that, even though the central axis of employment has shifted from manufacturing sector to service sector, the ratio of part-time work is very low. Its major reasons are low wage rate, insufficient fringe benefits including social insurance, and deficient job security, even though part-time work has positive characteristics. This study examines whether part-time work would be a decent one and an alternative to full-time work by answering two questions: one is who chooses part-time work and another is whether part-time work is satisfactory. Analyses of 3,971 wage workers in the 8th wave of the Korea Labor and Income Panel Survey reveal that, as expected, part-time work is prevalent among the young, married women, and the old supporting the results from previous studies and that choosing part-time work on one's initiatives has a significant positive effect on job satisfaction for women while it is not for men. Form the result, it can be concluded that part-time work can be an appropriate alternative for full-time work if one chooses it voluntarily.

Accurate estimation of milk production cost is very important for dairy farmers in establishing strategies for business management (e.g. planning a program for milk production, deciding the size of business and investment, determining the milk price for sale). Since the estimated cost of milk production is used as an important index to determine the basal price of milk in Korea, there has been much interest and debate on the method used to estimate milk production cost among the stakeholder. This study was thus carried out to identify problems in the current methodology for estimating cost of milk production, and to find a better way to improve it. We propose several alternatives and better ways to improve the current method for estimating cost of milk production. Estimation of the income and cost per head should be based on the number of cattle converted to grown cows. Cost estimation per liter of milk should be made for both whole milk and 3.4% milk fat corrected milk. The value of purchased cows and raised replacement heifers should be the same as their market value. The productive life span of cows should be less 4 years, and the terminal or salvage value of cows needs to be 30 to 40% less than her initial value. When calculating depreciation of cows over the productive life span, however, the salvage value should be 0 or 1 Korean won. On calculating labor costs, the farm labor wage corresponding to the average wage of nonfarm industrial workers should be assumed. Beside of these, better estimation procedures for other items are also given. The proposed methods from this study should improve the accuracy of estimation of milk production cost and help to achieve consensus among the stakeholder.

The purpose of this study is to analyze working mothers' demand for child care and housekeeping home services, and to investigate the present supply condition of home services in Korea. Data collection was implemented to examine the service demand of working mothers(n=700) in four areas. The data were analyzed with SPSS. The results were as follows: 1) For home-based child-care dispatch services social enterprises are superior to other private service suppliers in terms of the treatment of service workers, wages, and quality control. As for child care service contents, the provision of meals, and casual safeguards were mostly expected. The most important qualification for care providers was found to be in faithfulness, and the certification related with child care was required. An affordable wage range was perceived as ￦3,000~5,000 per hour, and part time services. For the time range, services which commenced before 9 am and terminated after between 5~6 pm were preferred. 2) For housekeeping dispatch services, standard services, including basic cleaning, preparation of meals and side dishes, special cleaning, and washing, were in demand. The required qualifications of housekeeping service providers were similar to those of child care service providers. Possessing certification was not considered as an important quality; however, personality and career type were important factors. An acceptable wage range was ￦3,000~5,000 per hour and part-time services were preferred. In terms of the service time range, services which commenced between 8~9 am and terminated between 5~7 pm were preferred.

The purpose of this study is to analyze the blind spots of Korea's employment insurance system from a gender perspective. The data used for this study was derived from 12th (2009) and 20th (2017) years of the Korean Labor and Income Panel Studies. Logistic regression analysis was performed to analyze the causes of the blind spot. As a result, the gender gap decreased by 5% in 2017 compared to that in 2009. In the coverage of employment insurance by gender, women are more likely to join when controlling for other demographic factors. If the conditions in the labor market are the same, then women's insurance coverage is likely to be higher than that of men. The policy suggestions are as follows. The current employment insurance system has a greater impact on the labor market characteristics than the difference in the participation rate according to gender itself. The results of this study show that bridging the gender gap in the labor market is an important way of bridging the gender gap in employment insurance coverage. In the short term, the social insurance subsidy program may be effective, but policy efforts are fundamentally needed to improve the employment environment of women and low-wage workers.
