Based on the Self-Determination Theory and previous studies, this study confirmed that basic psychological needs among Self-Determination Theory have an indirect influence on the postpartum depression through mediation of spousal support and marital satisfaction. A sample of 313 mothers who raises her child within a year of giving birth completed a questionnaire survey, and a structural equation model was utilized to analyze the data. Results indicated that both the measurement model, and the hypothesized structural model fit to the data. Meanwhile, when compared with the hypothesized model in which the path between all variables is established, the competitive model excluding the path from spousal support to postpartum depression has no difference in fitness, and was relatively simple and adopted as the final model. In the final model, the link between basic psychological needs and postpartum depression was partially mediated by spousal support and marital satisfaction. In addition, marital satisfaction was found to mediate completely the relationship between spousal support and postpartum depression. Based on the results, it would be helpful to identify the status of basic psychological needs, spouse support, and marriage satisfaction in counseling related to postpartum depression.

The purpose of this study is to investigate whether depression and social support have a multiple mediating effect in affecting the life satisfaction of the elderly with public and private transfer income. To this end, the 7th panel data (2017) among the data of the Korean Retirement & Income Study (KReLS) was used for analysis, and the analysis was conducted using structural equation modeling (SEM). As a result of the analysis, first, it was analyzed that the higher the public transfer income of the elderly, the lower the level of depression, the higher the social support, and the higher the satisfaction of life. Second, the partial mediating effect of depression was verified in the influence of the elderly's public transfer income and private transfer income on life satisfaction. Third, the partial mediating effect of social support was verified in the influence of the elderly's public transfer income and private transfer income on life satisfaction. Fourth, it was verified that the multiple mediating effects of depression and social support were significant in the effect of the elderly's public and private transfer income on life satisfaction. Based on the results of this analysis, policy proposals were made, such as revitalizing the Community Care program to strengthen the social support network of the elderly.

One of the construction methods applied as a pier foundation type is a single type cast-in-place pile. In applying a pile bent system as a foundation type, the main concern in designing can be said to secure the lateral bearing capacity of pile structure in system. In addition, to increase the rigidity of the pile structure, a method of increasing the lateral bearing capacity by reinforcing the pile structure with a casing has been used. However, although the reinforcing effect and appropriate reinforcing length of casing may vary depending on the soil conditions, there is insufficient studies on this, and for this reason, the entire pile structure in a pile bent system is reinforced with a casing, in the field. In addition, if the length of the entire pile is reinforced with a casing, it may lead to delays in construction and increase in construction costs. That is, in order to more effectively reinforce the pile structure with a casing, it is necessary to study the lateral bearing characteristics of the reinforced pile structure in system. And it should be determined the appropriate reinforcing length of the casing from the evaluated bearing characteristics. Therefore, in this study, the lateral bearing characteristics of piles applied with the reinforcing length of casing for each condition were evaluated through a numerical analysis. And, based on the analysis results, the appropriate reinforcing length of casing was proposed. As a result of the study, it was found that in order to effectively increase the lateral bearing capacity of pile structure, the reinforcing length of casing should be applied twice the influence range of the bending behavior of the pile, 1/β.

In this study, centrifuge model tests with 50 g gravitational condition were performed to evaluate the bearing capacity of very soft ground, improved by spreading geotextile and sand on the surface of ground, for the heavy machinery to be able to access. For undrained shear strength of ground model, prepared with the clay sampled from the field, being in the range of 3.1~11.7 kPa, bearing capacity tests were performed with the model footing and the loading system built to simulate the heavy machinery on the ground model treated with geotextile and sand. Test results were compared with theoretically and numerically evaluated ones. Test results about load-settlement curves showed that the bearing capacity increases with the increase of the undrained shear strength of ground. Punching shear or local shear failure was also observed. For a relatively low undrained shear strength of ground, settlement behavior is found to be crucial to evaluating the trafficability of machinery whereas bearing capacity becomes a dominant factor with the increase of undrained shear strength of ground. The method for assessing the bearing capacity of the ground related to trafficability of machinery is presented by acquiring the regression relationship between the contact pressure of machinery and settlements using load-settlement curves with the change of the undrained shear strength. Furthermore, results of numerical analyses about load-settlement relation are in relatively good agreement with those of centrifuge model test.

Laboratory model test with soft silty ground (ML) and polluted silty ground with wastewater and factory waste oil ($ML_p$) was conducted and the applicability of changes of bearing capacity from the increase of pollutants was compared and analyzed with existing findings. As silty ground polluted with wastewater and factory waste oil had increased contents of pollutants, plasticization of ground was fostered compared to soft silt ground due to the influence of pollutants, and characteristics of ground strength decreased. Critical surcharge value of soft silty ground $q_{cr}=4.14c_u$, ultimate bearing capacity value $q_{ult}=9.53c_u$, critical surcharge value of silty ground polluted with wastewater and factory waste oil $q_{cr}=1.78c_u$ and ultimate bearing capacity value $q_{ult}=4.39c_u$. Critical surcharge and ultimate bearing capacity of silty ground polluted with wastewater and factory waste oil were less than those of soft silty ground. It meant that shearing resistance due to the increase of pollutants decreased and rather a smaller value was obtained.

Family caregiving to the elderly is one of the most important social issues in recent Korea. Among various kinds of family caregivers, spouse caregivers particularly constitute a special group, generally characterized by continuous intimate association with the care recipients at many levels and by special commitments and responsibilities associated with the marriage bond. And the number of spouse caregiver is expected to increase in the future. Moreover, since a conjugal relation is consisted of husband and wife, their caregiving experiences and caregiving burden may vary by gender. Thus, the present study was to examine the effect of caregiving experience, especially caregiving motivation and social support focusing on the gender differences. We analysed 「2001 Survey of Care-giving Status and welfare Needs of Older Persons in Korea」 data by performing descriptive statistics, t-test and logistic regression. As a result, we found that the husband was likely to feel more burden when he started caregiving because of few alternatives. For wife caregivers, the less awareness of social support they had, the more possibility of economic burden they felt. With these results, we suggest the necessity of having gender-sensitive perspective in research and policy making for caregivers.
