Social capital theory provides a framework for analyzing the economic well-being. The purpose of this study is to analyze the age effect of social capital by comparing middle aged and the elderly, as well as to investigate the independent effects of social capital on their subjective economic well-being, respectively. The two concepts of "trust" and "social network" were used to measure the level of social capital. Comparisons between the age groups were made regarding the relationships between social capital and economic well-being of four age groups, including younger middle-aged, older middle-aged, younger elderly, and older elderly. Data from the $2^{nd}$ wave of the Korean Longitudinal Study of Ageing (KLoSA) were used. The final sample for this analysis is 8,406 respondents aged 45~84. The major findings are as follows. First, the level of social capital, trust and social network, is statistically different by age groups. Second, the model fits in the case of model including social capital variables are all larger than their counterparts in the four age groups. Third, social capital is "resource" that can contribute to increasing the subjective economic well-being. Based on the empirical results, implications for welfare policies related with issues of social security for the elderly in Korea are provided.

This study examined whether structural (coresidence, proximity) and associational (frequency of face-to-face contact, frequency of contact via phone, email or letter) solidarity between adult children and older parents may influence older parents' cognitive functioning. Adult children may help delay older parents' cognitive decline by promoting healthier lifestyle, engaging parents in complex everyday problem solving, and providing emotional support. The data consisted of men and women 65+ at Wave 1 who had at least one child 20+ and participated in at least two waves of the Korean Longitudinal Study of Ageing (KLoSA, N=3,961). Cognitive functioning was measured with the Korean version of the Mini Mental State Examination. Fixed effects models were estimated using the xtreg procedure in STATA. Findings suggest that increases in proximity with at least one adult child may lead to enhanced cognitive functioning among older parents. Neither transitioning to coresidence with at least one adult child nor increases in frequency of contact with at least one non-resident adult child was associated with changes in older parents' cognitive functioning. With older parents' increasing preference for living close by, but not necessarily living with adult children, greater proximity may provide more opportunities for reciprocal support exchanges between the two generations, leading to better cognitive functioning of older parents.

The purpose of this study was to assess middle-aged married men and women's access to family resources (economic and relationship) and to examine how this affects their life satisfaction. Data were drawn from the second wave of the Korean Longitudinal Study of Ageing (KLoSA). The sample consisted of 3,265 middle-aged married men and women aged between 45 and 60, who had children. The collected data were analyzed using multiple regression, ANOVA and the Scheff$\acute{e}$ctest using SPSS 18.0 The results showed that there was significant difference between men and women in terms of their access to economic and human relationship resources. In addition, the life satisfaction of the middle-aged was found to be significantly predicted by their access to economic and human relationship resources. In particular, the life satisfaction of group (A), who had low economic resource access but high family relationship satisfaction, was found to be higher than that of group (B), who had access to high economic resources but had low family relationship satisfaction This result indicated that there was an interaction effect between family resources. A number of policy implications were made.

This study aims to understand potential gender differences in the association between job characteristics and job satisfaction among older workers. The data are from 506 males and 202 females older than 55 from the first wave of the Korean Longitudinal Study of Ageing(KLoSA). Analyses focused on examining gender differences in the influences of subjective evaluation of work characteristics measured with education and skill fits of the work, work demands, customary early retirement, as well as more objective job conditions assessed with insurances by the employer, work hours, and salary on job satisfaction. Regression analyses revealed that female workers showed higher job satisfaction while job characteristics worked differently between genders to affect job satisfaction. For males, fitting the job with education and job demands were determining factors of job satisfaction, while the job with skills and work hours appeared to be significant factors for females. Results suggest that opportunities to utilize older workers' human capital and flexible working hours, especially for females workers would be helpful in promoting older adults' employment and satisfaction about their work.

The goal of this study was to examine the association between employment and depressive symptoms among older adults in Korea, including analysis of potential gender differences. Using a sample of Korean adults aged 60 years or older from the 2008(Time 2) and 2010(Time 3) national longitudinal survey data from the Korean Longitudinal Study of Ageing, we regressed measures of depressive symptoms at Time 3 on employment at Time 2 (and employment both at Time 2 and Time 3), controlling for Time 2 depressive symptoms, subjective physical health, and sociodemographic variables as well. First, there was no evidence that older adults with a job at Time 2 had significantly lower levels of depressive symptoms at Time 3 compared to their counterparts. However, multi-group analyses showed that the effect of employment at Time 2 on depression at Time 3 differed by gender. For older men, employment predicted better mental health over time. However, this was not the case for older women. As such work role provided benefits only for older men. Second, older adults with a job at both Time 2 and Time 3 reported significantly lower levels of depressive symptoms at Time 3 than older adults who did not have a job either at Time 2 or Time 3. However, only older men who were employed at both Time 2 and Time 3 reported significantly less depression than their counterparts. These findings suggest that the mental health effects of employment are contingent on gender.

Lately, as the problem of the aged poverty becomes a big social issue, this paper studies the problem of financial stability with respect to the income and consumption of before-and-after retirement generations. After dividing the data in Korean Longitudinal Study of Ageing(KLoSA) into retired and non-retired groups, this study compares the difference among ageing groups by cross analysis and t-test. First, the result tells that the total personal income of retired group is lower than the one of non-retired group. Second, the public pension income benefit ratio of retired group is only 30% of it's total income, and the amount of public pension appears to be 40% of the total pension income. The benefit ratio of the personal pension income is low as about 1% in both groups, The private transfer income of the retired group takes relatively large portion in its total personal income. Third, as people gets older, financial stability gets worse because consumption does not decrease as much as the income decreases. Fourth, it is turned out that the expectation of old life supporting from nation is low in both groups. Fifth, the factors that affects the income of the public pension in the retired group are gender, age, education, and health status, when compared with the factors to the personal total income of the non-retired group. In terms of policy, this paper emphasizes the needs of the intensification of the public pension and the support for the revitalization of the personal pension.

This study was attempt to derive the aging trajectories of Korean elderly people and identify its characteristics. In particular, this study used the successful aging model of Rowe and Kahn as an analytical framework. Using the Korean Longitudinal Study of Ageing(KLoSA), this study applied group-based multi-trajectory analysis to identify multiple aging trajectories in sample of Korean elder aged 65~74(n=2,682). This study also used several demographic characteristics as baseline predictors to identify the characteristics of each aging trajectory. Five dimensions were analyzed in the multi-trajectory model: chronic disease, physical functional limitation, cognitive functioning, depressive symptom and social engagement. As a result of the analysis, five aging trajectories were identified: successful aging(17.8%), usual aging (33.9%), health declining aging(18.2%), pathological aging(7.9%), and aging with mild cognitive impairment(22.1%). In general, the odds of experiencing successful aging were high in men, low-aged, highly educated, high-income, and spousal elderly. On the other hand, for the elderly, who are under-educated, low-income, and high-aged, there was a high probability of experiencing a relatively difficult aging process. In particular, the odds of experiencing a mild cognitive impairment aging was high in older, lower-income women without a spouse.

The objective of this study is to examine whether there are differences in participation in social activities and the effects of social activity types on the levels of happiness of the Korean older adults by age groups. The 5th wave(2014) of the Korean Longitudinal Study of Ageing (KLoSA) was used and a total of 3,273 elderly were selected from the 5th wave, who were 65 years old and older and who were not living with their offsprings. Chi-square test, ANOVA, and hierarchical multiple regression analysis were used. The rate of participation in economic activities declined with age and the levels of participation in leisure activities was higher in the young-old group in comparison to the middle- and the oldest- old groups. The levels of participation in family activities was higher in the middle- and the oldest-old groups in comparison to the young-old group. Socializing activities and religious activities measured by the frequencies of activities were not significantly different among the age groups. The results of a regression analysis of social activity types and their effects on happiness by age groups are the followings: 1) Leisure, socializing, religious, and family activities all (with the exception of economic activities) significantly affected the level of happiness of older persons in the young-old group. 2) However, only socializing and family activities in the middle-old age group, and only family activities in oldest-old group, had a statistically significant impact on the levels of happiness. These results support that the rates of participation in the five types of social activities and their effects on the levels of happiness were different by age groups. The implication of this study was to report that needs and the interests of older individuals are different by age groups based on empirical evidences.

The purpose of this study is to investigate the relationship between public care and family care. Public care for older adults began in 2008 with the implementation of the Long-Term Care insurance in South Korea. Although the expansion of public care has the purpose of reducing the care burden for the family, it is not easy to say whether the developments of public care system reduce the amount of family care for older family members. Theoretically, public care and family care are expected to have various relationships depending on the degree of the role and function(substitution, hierarchical compensatory, task specific, supplementation, complementarity). And literatures have showed inconsistent results depending on the country, data, and methods. In this study, we analyzed the relationship between two care types focusing on home care services for older persons. Analyses were based on data from the second(2008) to sixth(2016) waves of Korean Longitudinal Study of Ageing(KLoSA). To investigate elderly care dynamics in the households, we pooled the data for four changes between two periods(2008-2010, 2010-2012, 2012-2014, and 2014-2016). This study used an analytic sample of 262 older adults, who are aged 55 over and experienced public care at least one point of time. We used Fixed-Effects(FE) model to analyze the differences within the same individuals under the condition that time-invariant unobserved factors are controlled. This study distinguished the cases of entry into public care and other cases of exiting public care. The results showed that older people who are dependent on public care are less dependent on family care than before. In both entry and exit groups, negative relations were maintained, but in the entering stage of public care, the degree of negative relations was relatively small, whereas in the stage of maintaining or departing from public care, relatively negative relations were strong. At the beginning periods, even though public care increased, family care did not decrease significantly. On the other hand, at the time of ending public care and relying on family care, family care increased significantly. The results of this study show that the relationship between public care and family care is close to hierarchical compensatory model and varies according to the stage of caring transition. Also, it was found that the cases of transition from public care to family care have the biggest burden of elderly care than other groups.

The purpose of this study was to provide an understanding of the trajectories of multidimensional health among older adults, including depression, chronic diseases, and cognitive function. Data were drawn from the 1-6 waves of the Korean Longitudinal Study of Ageing(KLoSA), and a sample of 2,059 respondents aged 65 and older at baseline was used for the analyses. Latent growth curve models and growth mixture models were used to explore the changes in depression, chronic diseases, cognitive function, and heterogeneous trajectories among them. One-way ANOVAs with Scheffé post-hoc analysis and chi-square tests were used to find differences in sociodemographic characteristics, health behaviors, and life satisfaction across the latent trajectory classes. Latent growth curve models revealed that depressive symptoms and the number of chronic diseases increased over time, while cognitive function showed gradual decreases. Three heterogeneous patterns of multidimensional health trajectories were identified: normal aging, increase in chronic diseases, and chronic deterioration. Significant differences were observed in sociodemographic characteristics, health behaviors, and life satisfaction across the three latent classes. In particular, low educational attainment, household income, and life satisfaction were associated with the chronic deterioration class. Based on the findings, we discussed suggestions for health promotion education targeting older adults. This study also emphasizes the importance of home economics education in promoting health literacy across the life course.
