'Fun' may be a basic desire of all human beings, but studies that combine both education and enjoyment were very limited, with the exception of the sports and games subjects. As a result, this study focused on the fun induced from the actual site of education, beginning under the premise that this can increase the effectiveness of education. In particular, it has been concluded that more fun is especially required in compulsory education that disregards one's opinion, with the Social Service Personnel that are required to undergo two weeks of compulsory job training selected as the test subjects. In order to comprehend how the 'fun factor' from the Social Service Personnel' job training influences the educational effectiveness, the causal relationship between learning flow, group flow and learning satisfaction has been proven using the structural equation model. Through this, the median between fun and education was found, as well as whether fun education has an actual effect on educational effectiveness. In addition, it is an opportuniy to emphasise the need for enjoyable education for not just Social Service Personnel, but for all involuntary learners.

In this paper, the hydroelastic behavior of a mat-type large floating structure is analyzed in time domain by using mode superposition method. The time-memory function is estimated by Fourier transforming the wave damping coefficients, which are computed by a higher-order boundary element method based on potential theory. Meanwhile, the structural response is obtained by time integrating the eigenmodes of the structure. Numerical examples are made for three test cases on the scaled model of a mat-type large floating structure ; weight pull-up case, weight drop case and weight moving case. In all three cases, the numerical results coincide well with experimental data.

This study analyzes life experiences and prospects of poverty/welfare exit of the poor with work ability utilizing Mixed methodology. Based on Sequential Exploratory Design, it qualitatively analyzes 3 waves of qualitative panel data linked to Korea Welfare Panel Study(KWPS) and presents life changes of 14 poor in the context of their prospects of welfare/poverty exit. Then it proposes hypotheses on the role of education, household economy expectation, self-esteem in the prospects of poverty/welfare exit following the sequential exploratory design to quantitatively test qualitative findings utilizing KWPS(7th). The outcomes of the Structural Equation Model(SEM) suggest that household economy expectation plays mediating role between education and the prospects of welfare/poverty exit. This implies that anti-poverty policy needs to consider a psychological approach to enhance household economy expectations of the poor as well as other material support.

Circular concrete-filled tubes (CFTs) are composite members, which consists of a steel tube and concrete infill. CFTs have been used as building columns and bridge piers due to several advantages such as their strength-to-size efficiency and facilitation of rapid construction. Extensive experimental studies about CFT have been conducted for past decades. However experimental results alone are not sufficient to support the engineering of these components. Complementary advanced numerical models are needed to simulate the behavior of CFT to extend the experimental research and develop predictive tools required for design and evaluation of structural systems. In this study, a finite element modeling technique for CFT was developed. The confinement effects, and behavior of CFT subjected various types of loading predicted by the proposed finite element model for CFT were verified by comparing with test results.

A survey research was conducted for a sample of 306 adult children who have an elderly parent or both parents alive. The purpose of the research was to test a structural equation model which specified the effects of early family relationships on comtemporary relationships and assistance patterns between adult children and their parents. The data were analyzed using EQS for Windows 5.7, utilizing maximum likelihood method. The results showed that early family relationships affected filial concern first, which in turn affected the level of assistance provided by adult children for elderly parents. No direct effect has been found between early family relationships and the level of assistance by adult children for elderly parents. Filial concern was played as an intervening variable. Early family relationships gave no direct effects to adult children's intention to assist their parents. Here again, filial concern was played as an intervening factor. Adult children's intention to assist their parents had not been led directly to provision of actual support to parents by their adult children. Thus, it was identified that intention to support is one thing, and the actual support is another. Controlling for the effects of filial concern, overall, early family relationship patterns gave no differential effects to the different aspects of support provided to parents by their adult children. On the basis of these results, this paper provided both discussions and suggestions for some strategies of intervention in the present family relationships in order for the inter-generational exchange of supports to happen in the future.

This study focus on the effect of switching barrier on negative performance. To suggest the negative effect of switching barrier, we reviewed the researches on service-failure and attribution theory. The model which we present in the research study includes the antecedents and consequences of negative emotions(regret, resentment) that caused by switching barriers. The former factors consist of internal attribution and external attribution. The latter factors consist of acceptance, complain, negative word-of-mouth. Survey research is employed to test these hypotheses. Previous researches, such as service marketing, psychology, have been referenced to measure constructs. We collected data involving various service area, and used 189 respondents to analyze these data with LISREL structural modeling. The hypothesized relationships were statistically significant. Internal attribution had positive effect on regret and external attribution had positive effects on resentment. And then regret had significant effects on acceptance and complain behaviour. Also resentment strongly effects on complain behaviour and negative word-of-mouth. We concluded with managerial implications, including the potential to deeper understanding switching barrier.

For achieving economical fuel consumption, an increase in the load bearing capacity, and for environmental conservation, there is a constant demand for lightweight frames of commercial vehicles used in the transportation industry. In this study, a structural analysis of the frame of a heavy flat-bed trailer was performed to determine the optimal design of a new lightweight frame made of high-strength steel. To identify the key design parameters of the trailer frame, Taguchi's orthogonal array was used in the experiments. Using ANSYS, a commercial FEA program, the frame structure was optimized with respect to stress, deflection, and torsional stiffness by performing stress and vibration analyses. A physical model of the trailer was also built to verify the validity of the numerical analyses. Finally, an on-road fatigue test of the new lightweight frame made of the high-strength steel, ATOS80, was performed to confirm the durability of the new design.
