Various incentive policies for transshipment cargo have been enforced without any evaluation of the effectiveness. Therefore, the purpose of this study is to evaluate the effect of volume incentive on container transshipment cargo. To be different from previous studies, this study tries to quantitatively assess the incentive effects by using econometric techniques. The result derived from the ARIMA type models indicates that the total amount of the increased transshipment cargo during the last 7 years is about one million TEU. In the meanwhile, the multivariate long run equilibrium model implies that the increased transshipment cargo is less than 0.5 million TEU for the 7 years. Furthermore, the structural break tests indicate that the volume incentive does not change the model structures. It means that the effect of volume incentive is not statistically significant. Consequently, the test results conclude the effect of volume incentive on transshipment cargo is not significant although the volume of transshipment cargo is increased to some extent by volume incentive. Considering the magnitude of BPA's expenditure, we doubt the effectiveness of volume incentive. This study, therefore, encourages the port authority to research a more efficient way to induce transshipment cargo rather than focusing on only volume incentives.

A new Energy-Dissipating Sacrificial Device (EDSD) is developed for steel plate girders, which can effectively dissipate the energy stored in the structures during seismic actions. To verify the performance of the EDSD, various seismic responses of a sample bridge with the EDSD are analyzed in terms of energy, member forces and deformation. The full scale model tests are conducted to certify the performance of the EDSD when it is applied on existing bridges. Using the improved hysteretic model of the sacrificial member, the seismic analysis for an example bridge is performed. The results show that the proposed EDSD under seismic excitations can significantly decrease the energy stored in the bridge structures and reduce the relative displacements of each superstructure to the ground. The EDSD is also found to function as a structural fuse under strong ground motions, sacrificing itself to absorb the excessive energy. Consequently, economical enhancement of the seismic performance of bridges can be achieved by employing the newly developed energy-dissipating sacrificial device.

The goal of this study was to examine the relationship among students' personal variables(Korean language abilities, self-efficacy, student-teacher attachment relationships), teacher variable(perceptions of multi-cultural education) affecting on multi-cultural students' school adjustment. Structural equation modeling was performed to test the mediating role of self-efficacy and student-teacher attachment affecting multi-cultural students' school adjustment. 336 elementary students and their matching 264 elementary school teachers were participated for this study. The model fit for this study model was acceptable, =280.024, df=98, CFI=.930, RMSEA = .074. The results revealed that teacher's perceptions on multi-cultural education significantly related with student-teacher relationships. However, Korean language ability did not directly affect the school adjustment for multi-cultural background students. That is, self-efficacy and student-teacher relationships mediated between Korean language ability and school adjustment. Moreover student-teacher relationships seem to be the key mediating factor between other research variables and school adjustment. Further considerations and future directions based on results were discussed.

The purpose of this study was to construct and test a hypothetical model about impact of childhood trauma on Relationship Addiction of Korean adults the multiple mediating effects of rejection sensitivity and internalized shame. A purposive sample of 465 Korean adults was recruited from three provincial areas. The collected data were then analyzed using SPSS 23.0 and AMOS 23.0 programs. For data analysis, descriptive statistics and structural equation modeling were performed. Multiple mediating effects analysis using phantom variable and bootstrapping were implemented to verify the mediating effect of the research model. We found no significant direct effect of childhood trauma on relationship addiction, but the effects of childhood trauma on Relationship Addiction were successively multi-mediated by internalized shame and rejection sensitivity (B=.265, p<.01), and single-mediated by internalized shame (B=.496, p<.01). Based on the results of this study, it can be suggested that in order to prevent relationship addiction of adults, it is necessary to first explore whether he has experienced childhood trauma and thereby has not only internalized shame but also rejection sensitivity.

The purpose of this study was to investigate the impact of retirement stress, character strengths and marital dissatisfaction on depression. Additionally this study examined direct effects and indirect effects of character strengths and marital dissatisfaction. The participant group was composed of 197 retired men living in Daegu and Gyongsangbuk-do. The Retirement Stress Scale (RSS), Character Strengths Test (CST), Korean Marital Satisfaction Inventory (K-MSI), and Center for Epistemology Studies Depression scale (CES-D) were administered to participants. Structural Equation Modeling (SEM) with AMOS was used for the purpose of analysis. The results of the study were as follows. First, an increase in retirement stress was associated with higher levels of depression. Second, hierarchical regression analysis indicated that higher levels of optimism significantly predicted higher depression. Also hierarchical regression analysis indicated that lower levels of appreciation of beauty and excellence without optimism significantly predicted higher depression. Furthermore, increases in marital dissatisfaction were associated with higher levels of depression. Third, the constructed model including both direct effects and indirect effects appeared to fit better than alternative model in explaining relationships between retirement stress and depression. In other words, character strengths and marital dissatisfaction appeared to affect the depression levels of retired men directly and indirectly. To sum up, this study demonstrated that the factors which had an effect on depression in retired men, character strengths and harmonious marital relationships appeared to act as a buffer against depression in retired men. The current results might serve as basic data for psychological well-being programs for retired men. Finally, the limitations and implications of the current study were discussed.
