This study was attempted to verify the mediating effects of depression and physical health on the effect of Korean boomers' assets on life satisfaction. The 5th main survey data of the National Retirement Security Panel(KReIS) were used for this purpose. As a result, first, baby boomer's asset level has positive effect on life satisfaction. Second, the asset was able to confirm the positive effect of increasing physical health and satisfaction of life. Third, depression and physical health had a mediating effect between baby boomer's assets and life satisfaction. Based on the results of this study, policy suggestions were made to improve the life satisfaction by reducing the depression of baby boomers and improving physical health.

This research was conducted for the analysis the middle-old aged empty nest households' debt holdings and their financial status(emergency fund index, liquidity index, debt burden index) considering the level of income and assets. In order to accomplish this study, we made use of the KReIS third beta-version data. The results of the analysis were as follows. First, in all income asset groups there were more non-debts holding houses compared to debt holding houses. Moreover in debts holding houses, compared to other groups high income high assets groups were more. Second, the households that possessed more assets, had more debts. Third, the financial status of the households holding debts were more vulnerable compared to households that had no debts. Moreover, all income asset groups' emergency fund index were low. Households having no debts possessed low real assets and so the liquidity index was higher in holding debts households. In holding debts households, debt burden index was high. And especially these houses suffered from high debt burden when their income and asset were low.

The purpose of this study is to explore the transition to retirement of the middle-aged in Korea according to the notion of "the career job" and "the bridge job". In order to scrutinize basic elements for the transition, three aspects such as the job history of the middle-aged, the characteristics of the demographic and economic status were investigated through the one to three wave of Korean Retirement and Income Study(KReIS). In addition, the characteristics of the career job and the bridge job were analyzed by both descriptive statistics and the conditional transition probability. Moreover, the influential factors to the job status of the middle-aged were examined by the multi-nominal logistic regression. The results of the study are as followed: first, gradual retirement is increasing in the transition to retirement of the middle-aged in Korea. Over time, the career job is decreasing whilst bridge job is increasing. However, the quality of the bridge job is poorer than the career job in terms of wage, employment status, industry, and occupation. Lastly, the middle-aged who work in the bridge job have vulnerable characteristics, so they work in the bridge job to supplement their economic needs. The results can be influential in the adjustment of the labor policies for the middle-aged in Korea. Moreover, the partial pension system could be a good alternative since the pension system is needed to protect the vulnerable situation of the middle-aged in Korea.

This study analyzed private pension dependency of Korea and U.S. households using the most recent dataset of two countries. For this purpose, 2013 Korean Retirement and Income Study(KReIS) of national pension research institute in Korea and 2013 SCF(Survey of Consumer Finances) of FRB in U.S. were used. The private pension dependency was defined as the proportion of private pension wealth among total financial wealth in each household and tobit model was used to investigate determinants of private pension dependency of the two countries. After controlling for other factors, household income and net worth, age, educational attainment, and health status of householder were crucial determinants of private pension dependency for both countries. Householder's age, educational attainment, and health tend to increase the private pension dependency in Korea and U.S. However, household income and net worth affected the private pension dependency opposite direction. The private pension dependency increased with high level of income and net worth in Korea, while it decreased with high level of income and net worth in U.S. Results of this study provide useful implications for future pension system and policy in Korea.

This study tried to understand the effect of human capital of the elderly on life satisfaction. Data from the 8th KReIS additional survey were used for the study subjects, and the number of subjects was 1987. Descriptive statistics, t-test, ANOVA, and regression analysis were performed using SPSS 20.0. As a result, gender, age, education level, economic activity status, generational composition, spouse presence, and exercise type showed significant differences in life satisfaction. Life satisfaction and health status showed the highest positive (+) correlation, and monthly average income and education level showed the highest negative (-) correlation. As for human capital that affects life satisfaction, life satisfaction was higher in women than men, employed rather than unemployed, married generations, health, average monthly income, and regular exercise.

Purpose: Re-188-Hydroxyethylidene diphosphonate (HEDP) is a new cost-effective agent for systemic radioisotope therapy of metastatic bone pain. We investigated the influence of carrier for labeling and biodistribution of Re-188-HEDP using HEDP kit with or without carrier ($KReO_4$). Materials and Methods: The kits (HEDP 15 mg, gentisic acid 4 mg and $SnCl_2.2H_2O_2$ 4.5 mg) with or without carrier ($KReO_4$ 0.1 mg) were labeled with Re-188 solution, made available from an in-house generator by boiling for 15 min. We compared the labeling efficiency and stability of carrier-added and carrier-free preparations of Re-188-HEDP Biodistribution and imaging studies of each preparation were performed in ICR mice ($1.85{\sim}3.7MBq/0.1ml$) and SD rats ($74.1{\sim}85.2MBq/0.5ml$). Results: The carrier-added preparation showed high labeling efficiency (95% at pH 5) and high stability in serum (88%, 3 hr). However, the carrier-free preparation showed low labeling efficiency (59% at pH 5) and low stability (43%, 3 hr). The carrier-added preparation showed high uptake in bone and low uptake in stomach and kidneys. However, the carrier-free preparation showed lower uptake in bone and higher uptake in both stomach and kidneys, which is supposed to be due to released perrhenate. The carrier-added preparation also showed better images with higher skeletal accumulation, lower uptake in other organs and lower soft tissue uptake than the carrier-free preparation. Conclusion: The results of these studies clearly demonstrate that addition of carrier perrhenate is required for high labeling efficiency, stability, bone uptake and good image quality of Re-188-HEDP.

The purpose of this study is to examine income composition elements, poverty rate, and the effects of the transfer income on poverty decrease comparing grandparents-grandchildren households with living alone, couple, and living with adulthood children. Data come from the first(2005) and the second(2007) Korean Retirement and Income Study(KReIS) and the effects of poverty decrease is examined through reconstruction of LIS income definition. The main findings are as follows. First, the total income of the grandparents-grandchildren in 2006 is the lowest and about one-fourth of the households living with adulthood children. Second, the labor income of all households are increasing but the only grandparents-grandchildren's labor income is decreasing. Third, three of ten in grandparents- grandchildren households are in poverty, the poorest households's type is the grandparents-grandchildren in 2006. Fourth, four of ten in grandparents-grandchildren is able to escape poverty after including private and public transfer income. Especially, the effects of the public transfer income in grandparents-grandchildren households is lower in 2006 than in 2004, thus the role of public income security is strongly needed. Existing research was that the poorest type among the elderly group was the living-alone households, but this results show that grandparents -grandchildren households are the poorest group. Thus, income security policy is highly needed for poor skipped-generation households.
