he purpose of this study was to assess if the availability of the family-friendly corporate welfare programs had an effect on job satisfaction of married female employees after controlling for other factors such as job, personal and household characteristics. This study analyzed 215 working mothers who had the children under 6 years of age using the Korea Labor Panel Data(2005). The study established that married female employees working in the companies with more family-friendly corporate welfare programs exhibited higher job satisfaction on working hours, communication and human Relationships and other fringe benefits. Therefore, we recommended that family-friendly corporate welfare programs should be more available and developed in order to promote better job satisfaction for married female employees.

This study is to identify the factors deterring or precipitating the exit from welfare recipiency to labor market in the Korean social assistance program. The results from the empirical analyses of the Korea Welfare Panel Study(KOWEPS) show that the duration dependency is not due to increasing welfare dependency with duration, but to the fact that longer stayers have many vulnerable conditions to escape from poverty. Particularly, the main factors determining the transition from recipiency to labor market are not individual or household characteristics such as human or social capital. Those having adolescents of secondary education in their households or participating in some effective labor market program such as job placement service tend to have significant effects on the exit rates from recipiency. That means that the institution-related factors such as the education and health supports combined with benefits and the effective labor market programs are important in the translation from recipiency to labor market of working-age recipients in the Korean social assistance scheme.

Most of literatures on Korean child aggression are based on using the cross-sectional data sets. Although there is a related study with a longitudinal data set, it is assumed that the data sets measured repeatedly in the longitudinal data are mutually independent. A longitudinal data analysis for Korean child aggression is then necessary. This study is to analyze the effect of child development outcomes including academic achievement, self-esteem, depression anxiety, delinquency, victimization by peers, abuse by parents and internet using time on child aggression with Korea Welfare Panel Study data observed three times between 2006 and 2012. Since Korea Welfare Panel Study data have missing values, the missing at random is assumed. The linear mixed effect model and the restricted maximum likelihood estimation are considered.

As the global elderly population rapidly increases, the mental health of the elderly, particularly depression, has emerged as a significant social issue. This study analyzes the various factors influencing depression in the elderly based on the ICF model. Utilizing data from the Korea Welfare Panel Study, the study identifies the types of changes in depression among individuals aged 65 and older and examines the factors influencing these changes. This longitudinal secondary data analysis research uses the most recent three years of data (2021-2023) from the Korea Welfare Panel. The study sample consisted of 965 elderly individuals, and a latent class growth model was applied to identify the types of depression changes, while a multinomial logistic regression analysis was conducted to analyze the influencing factors. The analysis revealed that elderly depression could be categorized into four types: high-level decrease, high-level maintenance, low-level increase, and low-level maintenance. Main influencing factors included gender, age, education, poverty, social trust, social relationships, participation in economic activities, participation in religious activities, and health status. Particularly, social relationships and health status were significant factors affecting the types of depression changes. To mitigate depression in the elderly, a multifaceted approach considering both individual characteristics and social relationships and health status is required. The study suggests the development of community-based programs and trust-building activities at the community level to maintain and strengthen the social relationships of the elderly. These findings can serve as important foundational data for policies and practices aimed at improving the mental health of the elderly.

Objectives : This study was to investigate the effect of socioeconomic factors of smokers on their smoking cessation plans, using Korean Welfare Panel data. Methods : Of the 16,664 subjects who responded to the 10th Korean Welfare Panel Survey, 2,246 respondents who answered that they were currently smoking were included in this study. Results : The variables that affected smoking cessation plans were female, low education level, low level of smoking per day, and more than 24 hours of smoking cessation experience. Conclusions : Expanding the smoking cessation program for women, preventing smoking in schools and providing smoking cessation education will likely have a positive effect on smoking cessation plans. In addition, it would be helpful to increase the amount of smoking cessation support aimed at reducing the amount of cigarettes smoked per day and continuing smoking cessation for more than 24 hours.

The purpose of this survey was to collect basic data on breeding systems of animal welfare-approved laying hen farms in Korea. Questionnaires were mailed to 64 animal welfare-approved farms, and 20 questionnaires (31.3%) were returned. The housing systems were fabric coverlet (4 farms, representing 20%), naturally farmed (Yamagisi, 7 farms, 35%), and steel panel-framed housing (9 farms, 45%). The 20 farms had stocking densities of $2{\sim}3birds/m^2$ (2 farms; 10%), $4{\sim}5birds/m^2$ (10 farms; 50%), and $6{\sim}7birds/m^2$ (8 farms; 40%). Breeding methods were floor-housed (14 farms; 70%), free-range (3 farms; 15%), and floor plus free-range (3 farms; 15%). Stocking density was $4{\sim}6birds/m^2$ at most of the farms with fabric coverlet and naturally farmed housing and $6{\sim}7birds/m^2$ at seven farms (of 9 farms) with a steel panel-framed housing. The daily feed intake of 11 farms (55%) was between 120 and 130 g, which included 3 farms (15%) with fabric coverlet, 3 farms (15%) with naturally farmed housing, and 5 farms (25%) with steel panel-framed housing. The age of peak production was 24~28 weeks overall 20 farms. Over 80% of production on fabric coverlet, naturally farmed, and steel panel-framed house farms was on 3, 4 and 6 farms, respectively. Respiratory disease on the 20 farms represented 55% of total disease incidence, and of each housing type represented 75% (fabric coverlet), 70% (naturally farmed) and 33% (steel panel-framed). E. coli disease was only found in the steel panel-framed housing. Most of the animal welfare-approved eggs were sold at large markets or a real sale markets. Egg price was 200~250 won per egg. These results indicate the current situation of animal welfare-approved farms and could be caused that windowless poultry house was applied to animal welfare approved farms.

Objectives: While older adults using community care services are known to be vulnerable for depression, community care utilization (CCU) may help to improve the mental health of these elderly. To date, however, it is much less clear how CCU affects depressive symptoms in the elderly population. This study focuses on the trajectory of depressive symptoms across years of CCU among older adults in Korea. Methods: Using the 2006-2019 Korean Welfare Panel Survey, this study is focused on elderly born in 1940 or earlier and selected 3281 persons for baseline interviews in 2006. This consisted of 35 800 person-year observations during a period of 14 years. Panel data analysis were employed to construct years of CCU. Results: After controlling for covariates, linear term of years using community care was negatively associated with depressive symptoms, but a quadratic term was positively significant. The trajectory of depressive symptoms across the years of CCU follows a U-shaped curve. Older adults in the first year of using community care reported the highest level of depressive symptoms. However, a significant and steady decrease in depressive symptoms was observed during the following 9 years of CCU, which then gradually increased. The level of depressive symptoms at the 14th year of using community care remains significantly lower than the level at the outset of its utilization. Conclusions: This finding implies that CCU could be beneficial for improving mental health among older adults.

Purpose: The purpose of this study is to empirically evaluate the unintended welfare losses induced by paid sick leave, examine the severity of the unintended moral hazard loss caused by paid sick leave, and evaluate how much moral hazard cost society can accept to obtain paid sick leave benefits. Research Design, Data and Methodology: We examine the Medical Expenditure Panel Survey data collected in 2013 and 2014 by employing a panel probit analysis to control for individual heterogeneity. Results: The estimation result shows that the probability of absence due to paid sick leave increases from 4.91% to 7.84%. Among them, excluding the probability of increasing absence from 1.29% to 2.69% due to the actual disease, the probability of absence due to the moral hazard was estimated to be 2.41% to 6.49% in the proposed models. Based on the result, if we evaluate the increase in absence caused by moral hazard as a social cost, the estimated cost is approximately $174 to $297 per worker per year. Conclusion: Considering these expected costs, our society can obtain the access benefit from paid sick leave if we are willing to accept the moral hazard cost.

This study aims to examine the causality between socio-economic factors and Donate Behaviour. With the 10 years data in Korea Welfare Panel and Panal logit analysis, the analysis has done on the basis of household and sampled 134,500 data. The results of this research as follows: First, in demographic variables, women revealed as they donate more than men(${\beta}=.223$, p<.05). And the more the age grows, the less they donate or volunteer periodically(${\beta}=-.009$, p<.001). Second, in working conditions, paid workers showed less donate behavior than self-employment workers and economically inactive population(${\beta}=-.578$, p<.001). Third, Self-esteem(${\beta}=1.673$, p<.001)and Life satisfaction(${\beta}=1.01$, p<.001) showed significant effect on donate behavior. Lastly, scholarship of father(${\beta}=.211$, p<.001) revealed as significant on donate behavior. However, scholarship of mother did not showed significant effect. Also, the research had some limitations. First, the precision of the variables were not tested. Second, some variables to analyze were not in the data. Therefore, proper considerations on testing the precision of the variables and the method for measuring the missed variables are needed.
