The concept of household labor is composed of housework and family care, and it provides a framework for understanding daily life from the perspective of work-life balance. The purpose of this study was to investigate the household labor time of Korean adults by gender and generation over the last 20 years. Data was taken from the five Statistics Korea Life Time Surveys from 1999 (t1) to 2019 (t5) (n=69,196). The major results are as follows: first, gender and generation were found to have a significant relationship with household labor time over the study period. Household labor time for females was 3.8 times that of males in 1999, but females' household labor time decreased over the next 20 years while males' increased, including both housework and family care. The female participation rate in household work also remained steady, while that for males increased. Second, in the younger and middle generations, a similar gender and generational pattern was seen. Third, in the older generation, household time and participation rates for both females and males increased. The family welfare policy and theoretical implications of these results are discussed.

This study considered allocating and balancing time use as an important factor that determines the quality of life, and attempted to analyze the happiness of married women through the perspective of satisfaction with time use. We investigated the structure of time use, and analyzed the factors that affect happiness in the perspective of time use through the Time Use Survey data. Analyzing the happiness of married women, we found out that the level of happiness and the factors affecting happiness varied by generation. In the case of economically active women, the happiness of baby boomers and Generation X was mostly impacted by mandatory work hours, while the happiness of Generation Y was mostly impacted by the presence of care-dependent people. However, in the case of economically unactive women, the happiness of baby boomers and Generation X was mostly impacted by leisure and volunteering time that could be used freely, while the happiness of Generation Y was mostly impacted by the attitude toward gender roles. Therefore, through the perspective of time use, the happiness and the factors determining the happiness of married women differs by generation and economic activeness. This study has significant implications for the establishment of family policies for married women.

The Korea Wave has been spread out all over the world since 1990s. Therefore, it can be seen that the Korea wave phenomenon is one of determinants of international tourism demand for Korea in addition to the macro factors such as population, GDP per capita, exchange rate, distance, etc. Existing studies have focused on analyzing the impacts of the Korea wave on the international tourism demand for Korea by using the aggregated data. However, the impacts of the Korea wave inducing tourism vary in different age groups. In this study, we conduct empirical analysis in order to explore how different the effects of Korea wave on the demand of foreign tourists visiting to Korea in different age groups are. The estimation results show that the Korea Wave influences most on international tourism demand for Korea in the age group of the under-20s. Noticeable is that the estimated effects of the Korea Wave on international tourism demand for Korea in the age group of the over-50s are higher than those in the 30s and 40s. This indicates that the parent generations visit Korea together with their young children who are most affected by the Korea Wave. Through this study, it is necessary to develop strategies for tourism marketing linked to children and parents, and to develop tourism products to increase the number of foreign visitors to Korea in the 30s and 40s.

This study analyze the intergenerational transmission of poverty in Korea, using the first wave of Korea Welfare Panel Study. For this analysis, I produced poverty transition tables across generation and estimated logistic models to explore the effects of parent's poverty on the children's adulthood poverty. As the results, I found that parent's poverty reduced children's education level and then the low education level increased the likelihood that children experience poverty in their adulthood. In other words, parent's poverty might increase children's adulthood poverty through the mediating effects of education level. This mediating effects were also identified in the analyses by group and cohort. From the analyses by group, daughters rather than sons, those from urban rather than rural area, and the older cohort rather than younger cohort showed greater intergenerational transmission of poverty.

The purpose of this study is to investigate the differences of the factors affecting the entry of depression by generations and to present a practical strategy for preventing of depression by life-cycle. For this purpose, we analyzed the factors influencing the depression of adults, middle-aged and elderly people through the discrete-time hazard model. The results of this study are as follows: First, the lower the self-esteem, the lower the income satisfaction and the family satisfaction people have, the higher the likelihood of entering the depression they have. In addition, age, educational level, health status, presence of chronic diseases, employment status, regional area, and leisure life satisfaction were variables that showed difference by generation. In the case of adulthood(aged 20 ~ 39), unemployed persons are more likely to enter the depression than younger workers. On the other hand, the middle-aged(40 ~ 64 year olds) are more likely to enter the depression if they are older, have poor health status, have no chronic disease, and have low leisure satisfaction. Finally, older people(aged 65 and over) are more likely to enter the depression when the education level is higher, the health condition is worse, and the leisure satisfaction is lower. If they lived in an urban and rural complex, they are more likely to enter the depression. Based on these results, it is necessary to establish a support plan reflecting the characteristics revealed by generations in order to prevent the entry of depression.
