This study aimed to investigate the association between social support and the change of depressive symptoms and its difference by gender among Korean Baby Boomer. We used the Korean Longitudinal Study of Aging (KLoSA) 5th (in 2014) and 6th waves (in 2016). Samples were Korean Baby Boomer (born 1955 to 1963) who have spouse and children(N = 1,210). Dependent variable was depressive symptoms and independent variables were four social support variables (spousal relationship satisfaction, parent-child relationship satisfaction, frequency of social contact, and number of participation groups). Interaction variables between social support and gender were also included in the model. Hierarchical regression analysis with the lagged dependent variable was performed. Results showed that the higher the satisfaction of spousal relationship and the satisfaction of parent-child relationship, the less the depressive symptoms increased. All interaction variables were not significant. These findings mean that the support from the spouse and the child is helpful in lowering depressive symptoms, and the associations between social support and depressive symptoms are not different by gender among Baby Boomer. It implies that interventions for enhancing family relationships, especially spousal relationship and parent-child relationship, may be useful to reduce depressive symptoms among Korean Baby Boomer.

Bio materials of fibrinogen and collagen are widely used in tissue regeneration engineering. In this study, I aim to create a new dual-structure support using these two materials. Strategically, tissue regeneration takes priority over blood vessel regeneration, so by forming a fibrinogen support that helps blood vessel formation on the outside of the double support and placing collagen, which is more effective in tissue regeneration, in the center, a synergistic effect in new tissue regeneration is expected. Although these two materials have been used interchangeably in previous studies, there has been no report yet on making a support through the formation of a support structure for the core system. Therefore, the core of this study, the double scaffold, is to propose a method for manufacturing a core structure with a collagen scaffold on the inside and fibrinogen on the outside. The experimental results showed that the fibrinogen located on the outside of the scaffold resulted in rapid biodegradation and drug release due to strategic biodegradation of the dual structure scaffold. On the other hand, collagen scaffolds were found to be able to maintain drug release time relatively longer than fibrinogen scaffolds. In conclusion, it is believed that applying the method of creating a double scaffold will have a synergistic effect on defective tissue regeneration.

This study is to reveal the overall level of loneliness, depression and social supports of the elderly in rural area of Korea. The interview survey was performed in February 2001 with structured questionnaires to 486 respondents of 65 years or more of age who lived in Muan-gun area. The questionnaire was the revised translation of Japanese Elderly Study Which was composed of general characteristics, Japanese Loneliness Scale, abridged General Depression Scale(GDS) and Duke University social support Inventory. The following analyses adopted the analysis of covariate, t-test, and Chi- squire were used for some of the cross- sectional analyses. Average age of 486 respondents was 73.9 years old. 58.0% of the respondents noticed their partner or son as the primary consultant for the stressful situation. 56.2% of the respondents experienced the loss of their marital partner, health and/or friends. Average score of loneliness, GDS and social supports of the respondents that was each $35.54{\pm}8.38$, $7.23{\pm}2.21$ and $26.01{\pm}.90$. The overall level of depression seemed to be low as the 'pleasure to be alive' and 'happiness' scored high while the 'state of anger' and 'ominous presentiment' scored low. The level of loneliness and depression was positively correlated while the relationships were negative between loneliness and support and between depression and social support. These results suggested that social and health promotional programmes be necessary for the elderly of rural area. Further research would be required to specify the necessities.

Although several studies have been conducted on unification and the life of North Korean refugees, there have been few studies comparing the characteristics of North Korean refugees with South Korean workers, in terms of human resources in business administration. By considering the limitations of these prior studies, this study analyzed whether there are differences in factors affecting organizational commitment and turnover intention through a group comparative analysis between North Korean refugees and South Korean workers. For a comparative analysis between the two groups, we recruited 145 workers from North Korea and 213 South Korea-born workers. We found the following results with a multi-group structural equation model. We confirmed the measurement homogeneity by ensuring that both groups were equally aware of the measurement tools affecting organizational commitment and turnover intentions. As a result of testing the homogeneity of measurement, we also confirmed that there was a significant difference in optimism between the two groups; optimism affects organizational commitment and among social supports, affectionate support and interaction support affect organizational commitment. Analyzing the path between the two groups, we first were able to find that optimism influenced organizational commitment for both groups, in relation to positive psychological capital. However, in terms of degree, South Korean workers were found to be strongly affected. Second, with regard to social support, we were not able to find that affectionate support and interaction support have a significant impact on organizational commitment for South Korean workers, while for North Korean refugees, we confirmed that both supports have a significant impact. Third, we were unable to find any differences between the two group, in terms of other sub-components of positive psychological capital (self-efficacy, hope, and resiliency) or the sub-components of social support (informational support, tangible support). These results suggest that companies or managers employing North Korean refugee workers need to create an organizational environment that allows them to perceive social support, especially affectionate support and interaction support.

The purpose of this study was to examine the moderating and mediating effects of social support and social activity on the relationship between depression and quality of life in elderly women living alone. Subjects were 129 elderly living alone at K city in C province, from June to July, 2010. The data was analyzed using the SPSS program for descriptive statistics, Pearson's correlation coefficient and stepwise multiple regression. The degree of depression of elderly living alone was above the average(2.65), and that of quality of life was average(2.80). The correlated factors of quality of life among elderly women living alone included depression(r=-.745, p=.004), social support(r=.544, p=.000), leisure activity(r=.480, p=.024), and economic activity(r=.711, p=.001). Social support was an important mediator between the depression and quality of life in elderly women living alone. The moderating effects of social support and social activity between depression and quality of life in elderly women living alone were not significant. This study suggests that social support considered in enhancing the quality of life programs designed for elderly living alone. Further research needs to be done to refine moderating and mediating effects of social support, social activity including leisure activity, economic activity and volunteer activity.

This study was attempted to identify the marital intimacy, spousal support, sexual autonomy and empowerment of married immigrant Vietnamese women. This study was conducted to 119 Vietnamese women who migrated for marriage, and it took place from May to September, 2018. The data were analyzed using descriptive statistics, ANOVA and Pearson's correlation coefficients. Marital intimacy $3.17{\pm}0.69$, spousal support $3.45{\pm}0.94$, sexual autonomy $3.70{\pm}0.83$ and varied according to educational level(p=.011), and empowerment varied according to economic level(p<.001). There was a difference in intimacy and support depending on the marriage period. There is a very strong correlation between variables(p<.005). Married immigrant women showed moderate marital intimacy, spousal support, high correlation with sexual autonomy and two variables, and empowerment correlated with sexual autonomy. Based on these findings, it seems to be necessary to find a way to increase the empowerment of Vietnamese women and to develop an intervention programs.

The purpose of this study is to examined the relationship between social support, self-rated health status and life satisfaction among elderlies with chronic disease. For this study, 228 respondents suffered from chronic diseases and 75 healthy elderlies aged over 65 were analyzed. For the data analysis, a structural equation analysis and multi-group analysis were performed. As a result, higher levels of social support for elderlies with chronic diseases showed a higher level of life satisfaction, and the self-rated health status was found to be a significant mediator. The social support of the elderlies with chronic diseases significantly impacted their self-rated health status differently on healthy elderlies. To improve the self-rated health status and life satisfaction of elderlies with chronic disease, social services should be offered with social support providers. This study is meaningful in suggesting selective implications for elderlies with chronic disease.

This paper deals with the bearing capacity behaviour of geosynthetic-reinforced stone column(GRSC) constructed in soft ground, as part of an investigation regarding the applicability of GRSC in Korea. In this study, two-dimensional finite element analyses were performed to investigate the effect of relevant design factors on the bearing capacity behaviour. The parametric study is performed for various influencing factors. The results indicated that the geogrid encasement tends to significantly improve the load carrying capacity of a stone column. Also found were that the geogrid encasement length and its stiffness significantly affect the load carrying capacity behaviour of GRSC, and that the encasement length of three times the stone column diameter is sufficient in mobilizing the full reinforcement effect. Practical implications of the findings are discussed.

Stone column is one of the ground improvement systems which is being used for accelerating consolidation and increasing bearing capacity for settlement sensitive structures like load embankments, bridge abutments, oil storage tanks etc. The effects of this method are enhancement of ground bearing capacity, reduction of settlement, prevention of liquefaction and prevention of lateral ground movement. Recently, geosynthetic reinforced (encased) stone column approach has been developed to improve its load carrying capacity through increasing confinement effect. Although such a concept has successfully been applied in practice, fundamentals of the method have not been fully explored. This paper presents the results of an investigation on the bearing capacity and failure mechanism of geogrid-encased stone column by model tests. The results of the analyses indicated improved bearing capacity of the geogrid reinforced stone column method over the conventional strone column method with no encasing.
