The purpose of this research is to identify if psychological temptation, site quality and sense of community influence user's flow and addiction and if causalities among flow, addiction, customer satisfaction and customer loyalty are different between Korean and Japanese online games. To perform our research, we use MCSF(Multi-group Confirmatory Factor Analysis) and MSEM(Multi-group Structural Equation Model). The empirical results of SEM(Structural Equation Model) including high-order factor analysis indicate that all of paths in our model are the same for both countries. Therefore, site quality and sense of community have impacts on the flow, while on the other hand, psychological temptation has impacts on the addiction. Customer satisfaction and loyalty are positively related not with the addiction but with the flow. In addition, customer loyalty is significantly influenced by the flow and the customer satisfaction. In Conclusion, the empirical results of MSEM(Multi-group Structural Equation Model) indicate sense of community to flow, flow to loyalty and customer satisfaction to loyalty are different between Korea and Japan. This indicates that companies to penetrate into Japa online game industry should have a concern with Japanese Social and Cultural features and to develop strategies which correspond with Japanese culture.

The purpose of this research is to identify causalities among service quality, service value, customer satisfaction and customer loyalty and to compare the causalities between in-patients and out-patients. A multi-group structural equation model was used to test the hypothesis of conceptual model. Empirical results indicate that two factors such as assurance and empathy have direct impact on service value and customer satisfaction in both the patients. In the results of multi-group comparison test, however, the path coefficients from service value to customer loyalty and from customer satisfaction to customer loyalty were different across the two groups. In out-patients, customer loyalty is more positively related with service value. In in-patients, customer loyalty is more positively related with customer satisfaction. It is proven that service quality influences customer loyalty. Therefore To compete successfully in today's volatile & competitive medical markets, the hospital needs to manage the service quality, considering the type of patients.

The purpose of this research is to analyze the difference of Structural Equation Model which shows the path between BRQ and its performance variables according to purchase product types-fashion brand types, clothing item groups. The subjects were women in their 20s to 40s living in Seoul and Metropolitan areas, and 482 copies of questionnaire were analyzed. Multi-Group Analysis of AMOS 5.0 Package was used to investigate structural equation model according to fashion brand types and clothing item groups. The results of this study were as follows. As for fashion brand types, there appeared to be significant differences between high price brand type and medium-low price brand type for three paths, namely brand satisfaction to brand loyalty, BRQ to brand attitude, and brand attitude to brand loyalty. However the verification of structural equation model according to clothing item groups showed no significant differences between formal wear and informal wear. Consequently, BRQ was proved to affect brand satisfaction and brand loyalty, and brand satisfaction was the important intermediate variable between BRQ and brand loyalty. As consumers were likely to show the difference of structural equation model according to the price of purchase goods, differencial marketing strategy would be suggested.

Internet shopping mall has dual nature of information technology features defined by the web-based application system and marketing features explained by the shopping marketplaces. The purpose of this study aims at analyzing the consumer's attempt to purchase and re-purchase intention to the internet shopping mall to combine the IT perspective and the marketing perspective. This paper develop the integrated research model with the acceptance behaviors of customers through consumer's purchase decision process(pre-purchase stage and post-purchase stage). The results from an empirical survey as follows: First, the integrated model is valid in predicting the acceptance of the internet shopping malls by using structured equation modeling. Second, there are the differences between pre-purchase stage and post-purchase stage by each conceptual constructs. Finally, the results of MSEM(Multi-group Structured Equation Modeling) indicate the perceived ease of use and perceived trust to the attitude to the internet shopping mall is more effectively predicted at the pre-purchase stage. Vice versa, the perceived usefulness to the intention to the purchase intention of internet shopping mall is more effectively predicted at the post-purchase stage. This study provides an integrative approach to develop the effective and successful internet shopping mall strategy.

This study begins with an interest in community capacity, the basis for mobilizing community action and the driving force of community development. The study aims to identify the structural equation model of community capacity, social participation, satisfaction in life, and the impact relationship and to verify the differences between urban and rural areas. The analysis data used the 2018Korean Social Integration Survey, which is the statistical data for national approval. The analysis method was performed by using SPSS was used to perform descriptive analysis and t-test, and the structural equation model. Multi-group analysis of AMOS was also performed to verify the research model. As the result of analysis, both the condition and status of community capacity and social participation, which are products of community capacity, showed a higher average of rural areas than urban areas. As a result of the analysis of the structural equation model between community capacity, social participation, and life satisfaction, differences between rural and urban groups were identified. In rural areas, both the capacity-condition and the capacity-status variables act as positive factors for social participation and life satisfaction, but in urban areas, the path of capacity-condition, social participation, capacity-status and life satisfaction was significant. On the other hand, social participation variables acted as a factor of direct and indirect negatively influence on life satisfaction. Therefore, it can be said that the quality of community capacity in rural areas is superior to that of urban areas.

A rigorous research is underway in our team, for the design and development of high figure of merits (ZT= 1.5${\sim}$2.0) micro-thermoelectric coolers. This paper discusses the fabrication process that we are using for developing the $Sb_2Te_3-Bi_2Te_3$ micro-thermoelectric cooling modules. It describes how to obtain the mechanical properties of the thin film TEC elements and reports the results of an equation-based multiphysics modeling of the micro-TEC modules. In this study the thermoelectric thin films were deposited on Si substrates using co-sputtering method. The physical mechanical properties of the prepared films were measured by nanoindentation testing method while the thermal and electrical properties required for modeling were obtained from existing literature. A finite element model was developed using an equation-based multiphysics modeling by the commercial finite element code FEMLAB. The model was solved for different operating conditions. The temperature and the stress distributions in the P and N elements of the TEC as well as in the metal connector were obtained. The temperature distributions of the system obtained from simulation results showed good agreement with the analytical results existing in literature. In addition, it was found that the maximum stress in the system occurs at the bonding part of the TEC i.e. between the metal connectors and TE elements of the module.
