This study tried to explore the quantitative travel heterogeneity between elderly and non elderly people, focusing on urban and rural areas in south Chungcheong province. For the analysis, a PLS(Partial least square) model is applied with economic and traffic environment characteristics of the urban and rural areas. The characteristics of elderly and non elderly people in the urban and rural areas are derived from the 2011 person trip survey. As a result, the study found out that the key factors affect on elderly people in the urban and rural areas are bus operation interval, number of bus operation routes, number of household member, and a monthly average income of household. In case of non elderly people, areas economic factors such as GRDP, the rate of economic activity, and employment status as well as those of elderly people. Meanwhile, female elderly people in rural area have more sensitivity compared to male elderly people and the gender heterogeneity is not revealed in non elderly people.

The purpose of this study is comparing fiscal sustainability of 17 welfare states. Borrowed the concept of fiscal space to Ostry et al(2010) and Ghosh et al(2011), this study measures the fiscal sustainability in welfare states. Using data collected from 20 OECD countries from 1986 to 2013, this study attempts to evaluate the financial sustainability of each country. As a result, it is necessary that the appropriate level of tax burden is secured. Tax revenue is the funded basis for maintaining the welfare state, so increasing tax compliance to offset the negative impact of increasing welfare spending will promote social cohesion. In therms of tax structure, in accordance with the ability to pay principle, it is important to raise the equity between the source of taxation. Reducing the gap between labor and capital tax is required to achieve horizontal equity, It is also useful to utilize the financial base of the welfare state by broadening the tax base though a consumption tax. Improving the vertical equity can also make a positive contribution to the fiscal sustainability of the welfare state.

This study purports to analyze how individuals' labor market integration affect their transition to marriage. In doing so, I construct variables for job stability and continuity to represent labor market integration using labor force status and years of participation at the time of marriage and during the three years up to the point of marriage. In particular, I focus on differential effects of these labor market integration on the transition to marriage by cohorts: one for those who are likely to enter the labor market after the 1997 financial crisis and the other for those who are before the 1997 financial crisis. I used the Korean Labor and Income Panel Study and analyzed individuals aged above 18 in 2008. The main results are as follows. being currently employed and regular employment increases hazards of the first marriage for men but decreases them for women. long-term no-jobs decreases hazards of marriage for both women and men. long-term regular employment increases hazards of marriage for women but not for men at the statistically significant level. These effects vary by cohorts implying that recent economic and labor market instability deteriorated economic conditions for the youth making transitions to marriage.

The purpose of this Convergence study was to provide basic data to prevent and intervene in depression of the young adult by examining the effect of COVID-19 on depression in single-person households, focusing on gender differences. The research was conducted with 198 male and 218 female young adults were sampled from the Seoul Welfare Survey(2020) and data were analyzed through hierarchical regression analysis. As a result of the analysis, negative changes in employment, income, and emotions due to Corona significantly increased the level of depression among young people. And the effects of COVID-19 sub-factors were different between male and female. Based on result, clinical and policy implications were suggested for managing with depression among youth in our society in consideration of gender differences in crisis situations such as COVID-19.

The purpose of this study is to classify the degree of change of job discrimination of the disabled according to time and to identify factors affecting life satisfaction according to each type. For this study, data from the 3rd to 8th year of the employment panel for the disabled were used and 1,227 data were used. The longitudinal profile of the disabled person's discrimination was classified through latent profile growth analysis(LPGA), and then influential factors were verified through binomial logistic regression analysis. First, the types of change of the job discrimination of the disabled were represented as the decrease group and the increase group. The factors influencing the job discrimination were the degree of disability, chronic diseases, gross income, and life satisfaction. Second, the factors of predicting the life satisfaction according to the types of job discrimination of the disabled are as follows: job discrimination, decrease and increase group have higher life satisfaction as the self - esteem and socioeconomic status are higher. Based on these results, this study suggested the implications of this study to cope with the discrimination of the workplace with the disabled.
