The purpose of this research is to confirm how the determinant factors for shopping mall selection (proximity, parking facility, benefits, mutual interaction effects, physical environment, surroundings) affect attractiveness (image and appraisal) of the traditional markets and revisit intention and suggest strategic methods for revitalization of the traditional markets. Results of this research are drawn from a survey of customers who visit any of the twenty-two traditional markets in the Seoul area at least twice a week. Moreover, the theory is verified through the structural equation model analysis using the SPSS win 18.0 and AMOS 18 version statistics package. From the determinant factors of visiting traditional markets, parking facility, physical environment, and the surroundings were significant in image attractiveness; benefits, mutual interaction effects, and physical environment showed significant effects on appraisal attractiveness. Additionally, image attractiveness was not significantly influential in retention proneness while appraisal attractiveness was a key factor in deciding whether or not to revisit. Therefore, improvement in image is important but appraisal aspects like product reliability that customers can personally assess, are more essential for revitalization of traditional markets.

Rice (Oryza sativa) is the most important staple crop in Korea. With its small genome size of 389Mb, rice is a model plant for genome research. We analyzed expressed sequence tag (EST) clones from immature seeds of rice (cv. Ilpum) at 20 days after heading. The 25,668 EST clones were clustered by using SeqMan program and 7,509 clones were selected as unique clones. We compared the 7,509 unique genes with KOME database including the 32,127 FL-cDNA in rice. Finally, 4,990 clones were homologous and 2,519 clones non-homologous to FL-cDNA clones. In addition, we mapped the 7,509 cDNA clones by using TIGR rice pseudomolecule version 5. Ultimately, 7,347 clones were matched to be significant clones related to the TIGR rice pseudomolecules, but 162 clones were unmapped. For the clustering of orthologous group genes, we further analyzed the 7,509 EST clones from immature seeds using NCBI clusters of orthologous groups database. Among the clones, 4,968 clones were categorized into information storage and processing, cellular processes and signaling, metabolism and poorly characterized genes, proportioning 799 (14.89%), 1,536 (28.3%), 1,148 (21.2%) and 1,936 (35.7%) clones to the previous four categories, respectively.

As the recent development of computing architecture and application software technology, real world simulation, which is the ultimate destination of computer simulation, is emerging as a practical issue in several research sectors. In this paper, metal plate motion in a square shock tube for small time interval was calculated using a supercomputing-based fluid-structure-combustion multi-physics simulation tool called Illinois Rocstar, developed in a US national R amp; D program at the University of Illinois. Afterwards, the simulation results were compared with those from experiments. The coupled solvers for unsteady compressible fluid dynamics and for structural analysis were based on the finite volume structured grid system and the large deformation linear elastic model, respectively. In addition, a strong correlation between calculation and experiment was shown, probably because of the predictor-corrector time-integration scheme framework. In the future, additional validation studies and code improvements for higher accuracy will be conducted to obtain a reliable open-source software research tool.

To examine how usage of social network services(SNS) can affect users' satisfaction through their involvement to SNS. This study first explored the usage motives on the SNS by reviewing previous studies which are from the perspectives of usage and gratification theory. The structural equation modeling(SEM) approach was used to validate the model and Lisrel was used to analyze 306 data which were collected from college students who have SNS using experiences. The results showed that the motives of information seeking and self-expression have no significant influence on affective involvement to SNS and other hypotheses were all accepted. In order to investigate the relationship of usage motives-involvement-satisfaction between different genders, path analysis in male group and female group were done respectively. The results showed that in the case of male group, the motivation of information seeking, entertainment, and self-expression have positive effect on affective involvement, while only the entertainment motive can increase the cognitive involvement. In the case of female group, socializing motive and entertainment motive have positive effect on both affective involvement and cognitive involvement, but the information seeking motive and self-expression motive can not influence the formulation of emotion in SNS.

This study approached the military security problem from the viewpoint of social psychology in view of the fact that the military security problem has been focused on the technical field such as cyber security along with the development of defense science and technology. In this background, we examined the causal relationship between variables after extracting variables affecting the security problem of the military through previous research. The significance of the study results is as follows. First, the military culture has a direct and indirect influence on improving the willingness to adhere to security and the security level of military organizations, as well as contributing to the establishment of military values. This indicates that the overall organizational culture of the current military is influencing the security consciousness of the soldiers and the achievement of organizational security, while at the same time showing the need for effort to create the right organizational culture. Second, the values of soldiers had a positive effect on the willingness of the individual to obey the security and the security performance. Values begin with an understanding of organizational culture and indicate that efforts can be made to establish an organizational security posture when the right values are formed. Third, we have improved the completeness of the study by verifying the causal relationship by extracting variables that correspond to the context of the ROK military.

The purpose of this study was to explore the relationship between the subjective consciousness and life satisfaction of the elderly, and to see how depression affects this relationship. This includes a new way of thinking about the causes of the elderly's life satisfaction, not only for individual factors, but also for subjective class consciousness. For this aim, we examine the degree of subjective class consciousness, life satisfaction and depression of the elderly, and verify mediation effects of depression between subjective class consciousness and life satisfaction. This study utilized data obtained from the 5th version of the Korea Longitudinal Study on Aging 2014, and considered data from 4,222 elderly aged 65 and over. As a means of study, a structural equation model analysis was conducted. The results were as follows: First, it was confirmed that the subjective class consciousness of the elderly may influence life satisfaction. It was also confirmed that the subjective class consciousness of the elderly also affected depression and life satisfaction among the elderly. When subjective class consciousness was high, depression was low and life satisfaction was high. When depression was low, life satisfaction was high. Second, depression had the mediation effect in which subjective class consciousness affects life satisfaction. Based on these results, this author suggests practical and political issues concerning social welfare to prevent and reduce depression and increase life satisfaction through improving the subjective class consciousness of the elderly. First, policy measures should enhance social capital through housing support policies and leisure use support to enhance the subjective class consciousness of the elderly. Second, the provision of services for the elderly through the establishment of a community-based network to reduce depression should be promoted.

This study aimed to examine the changes in the health status, social network and satisfaction of caregivers as a result of caregiving using a structural equation model. As a result, it was found that caregiving increased the level of depression and decreased the subjective health status in both men and women. The social network and satisfaction were found to differ according to gender. For the women caregivers, caregiving affected their subjective health status and depression. In the case of the men caregivers, the total effect of caregiving on their subjective health was 1.087(p<.05), while the indirect effect was 0.546(p<.05). Also, caregiving affected the subjective health status of the male caregivers through the functional family network as a mediating factor(0.42, p<.01). The results suggest the necessity to take these gender differences into consideration when discussing the health of caregivers. Also, the functional family network needs to be strengthened to prevent the deterioration of the health status of male caregivers.
