This study examined one of the contemporary issues that may be interesting to academics and practitioners regarding the driving force of the growth rate for the firms belonging to the chaebols in the Korean capital markets. With respect to the empirical results obtained from two hypothesis tests, the first hypothesis was to identify any financial determinants on the growth rate by applying both dynamic panel data and static panel data models. The debt ratios relevant to the book- and market-value showed their positive relationships with the DV of GROWTH1, along with other significant IDVs such as one-period lagged DV of GROWTH_1, SIZE1 and FOS with statistical significance. Second, by employing conditional quantile regression (CQR) analysis, the control variables, such as ROA, SMARKET, time dummy variable of F2010 and F2011, and the industry dummies of IND3 and IND10, provided evidence of their significant influences on DV of GROWTH1.

The study was conducted to identify factors that affect the first childbearing decisions among married working women in South Korea and thereby to gain insight into effective ways to improve relatively low fertility and unfavorable workplace conditions for women of childbearing age. This study used the merged data(1st-5th waves) from Korean Longitudinal Survey of Women and Families (KLoWF), which were measured by the Korean Women's Development Institute. With 1,020 married business women, cross tab and binary logistic regression were conducted to determine which factors were significantly associated with the first childbearing decisions.

The purpose of this study was to examine the effect of vision and hearing limitation on the onset of disability among Korean elderly with the consideration of social participation and depression. Study population consisted of 2,670 people aged 65 and above who participated in both the 1st(2006) and 2nd(2008) wave of the Korean Longitudinal Study of Aging(KLoSA), and also reported no ADL or IADL disability in 2006. As the results, first, it found that vision and hearing limitation, social participation, and depression were significant risk factors for the onset of IADL disability in unadjusted analysis. After multivariable adjustment, however, only vision limitation showed significant association with the onset of IADL disability. Second, in the logistic analysis with four categorized variables(vision/hearing limitation + social participation, vision/hearing limitation + depression), the elderly who had vision or hearing limitation had a significantly 1.7 times higher odds ratio for disability onset if they also had low social participation compared with those who had no vision or hearing limitation, and high social participation. Whereas, depression was not significantly associated with the relationship between vision or hearing limitation, and disability onset. The study suggests that the intervention program developed to prevent social isolation of older people with vision or hearing limitation, may be helpful to reduce and postpone the risk of disability onset as well as early detection and treatment of vision or hearing problems.

The purpose of this study is to examine the moderated mediation effects of parenting functioning on the relations between deviant peer's influences and delinquent behaviors in adolescence. To investigate the moderated mediation effects, simple slope test and bootstrapping method based on multiple linear regression(MLR) model were used. This study used data from wave 1-2(2003-2004) of the Korea Youth Panel Survey(KYPS). Results showed that poorer parenting increased the probability that adolescents would affiliated with deviant peers, and more association with deviant peers, in turn, was related to delinquency. There was statistical significant interaction between affiliation with deviant peers and parenting in the model for delinquency. It implied that the relation between deviant peers and delinquency depends on the quality of parenting. Finally, indirect effect of earlier parenting on delinquent behavior through affiliation with deviant peers was moderated by later parenting. These results help clarify the conditions under which exposure to parenting behaviors can buffer the negative effect of deviant best friends on delinquent behaviors in adolescence. Practice and policy implications as well as further research topic were discussed to aid the search for highly effective preventive and treatment interventions.

This study aims to examine the mutual influences of negative parenting attitudes, self-esteem, and life satisfaction perceived by adolescent children through longitudinal perspective. Data from the first to third years of the panel of the first year middle school students were used among the 2018 data of the Korean Children and Youth Panel Survey (KCYPS) of the Korea Youth Policy Institute. The longitudinal correlation was analyzed by applying the autoregressive cross-lagged model which can determine the direction of longitudinal causality between variables. As a result of the analysis, it was found that the negative parenting attitudes, self-esteem, and life satisfaction perceived by adolescents had a positive effect on the negative parenting attitude perception, self-esteem, and life satisfaction at later times, respectively. In addition, the higher the negative parenting attitude at the previous point was, the lower the self-esteem or life satisfaction afterward. The higher the life satisfaction, the lower the negative parenting attitude of the parents, and the higher the self-esteem. Recognition of negative parenting attitudes of parents lowered the self-esteem of adolescents, whereas the cross-delay coefficient from self-esteem to negative parenting attitude perception was not significant. Through these results, the longitudinal relationship between negative parenting attitude perception of adolescence, self-esteem, and life satisfaction was confirmed and efforts to form positive self-esteem and improve life satisfaction were discussed.

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.

The purpose of this study is to examine the associations among attention deficit/hyperactivity, social withdrawal, peer relationships, and depression in early adolescence. Gender differences in the associations were also examined. This study investigated these relationships and the gender differences using structural equation modeling multi-group analysis. The third wave data from Korea Children and Youth Panel Survey (KCYPS) of fourth graders were analyzed. The results indicated that attention deficit/hyperactivity had significant effects on depression directly and indirectly through social withdrawal and peer relationships. These results suggest that new programs should be developed to prevent or alleviate depression associated with attention deficit/hyperactivity among adolescents. Specifically, social withdrawal and peer relationships need to be emphasized in planning prevention or intervention programs to promote mental health of adolescents with attention deficit/hyperactivity.

The number of collaboration professors has significantly increased since the last decade, along with rapid technological developments and the necessity of entrepreneurial universities. Despite the expansion of collaboration professor recruitment, few empirical studies have examined the contribution of collaboration professors to university-industry collaboration. In particular, we do not have sufficient knowledge about the role of collaboration professors in the start-ups of undergraduate students, which is one of major duties of these professors. Following previous studies, this study constructs panel data of 203 universities explaining the proportions of collaboration professors, activities of undergraduate students, support of universities for students preparing new firms, and attributes of universities from 2017 to 2019. The results indicate that the percentage of collaboration professors is not statistically related with the start-ups of undergraduate students, whereas that of full-time professors working at organizations specializing in start-ups is positively and significantly associated with the number of new firms of undergraduate students. In addition, the percentage of students who had attended the start-up camps and the availability of financial support from universities for students who attempt to create new firms positively influence the start-ups of undergraduate students.

The paper tried to determine relationships between volunteering and hypertension risks, symptom betterment, activity difficulty occurrences, and medicine treatment among middle-aged and older adults, with a prospective cohort study. Multilevel mixed-effects generalized linear models were used for the analysis of longitudinal panel data collected over 10 years from 2008 to 2018, using 5,867 cohort samples. The results showed that those who volunteered at least 200 hours per year were 3.4 times more lower than not-volunteering in risks of hypertension, those who volunteered yearly 50~99 hours were a lot more improved than not-volunteering in the symptom betterment, those who volunteered yearly at least 200 hours were 7.7 times lower than not-volunteering in activity difficulty occurrences, and those who volunteered yearly 50~99 hours were 2.5 times lower than not-volunteering in the occurrences of medicine treatment. These indicate that volunteering among middle-aged and older adults may have health benefits against incident hypertension. Finally the thesis discusses the study limitations, future directions of studies, and the practices implications.
