The following "Periodic Jacobi Procrustes" problem is studied: find the Periodic Jacobi matrix X which minimizes the Frobenius (or Euclidean) norm of AX - B, with A and B as given rectangular matrices. The class of Procrustes problems has many application in the biological, physical and social sciences just as in the investigation of elastic structures. The different problems are obtained varying the structure of the matrices belonging to the feasible set. Higham has solved the orthogonal, the symmetric and the positive definite cases. Andersson and Elfving have studied the symmetric positive semidefinite case and the (symmetric) elementwise nonnegative case. In this contribution, we extend and develop these research, however, in a relatively simple way. Numerical difficulties are discussed and illustrated by examples.

This study investigates internet shopping behavior of consumers. The rapid growth of the internet shopping markets is solely dependent on the voluntary adoption of internet shopping medium by the personal users. But the studies on this topic are very limited. Based on these facts, this study, recognizing the internet shopping medium as an innovation, studies how consumers understand and use innovative internet shopping medium by applying and extending the technology acceptance model proposed by Davis et. al.(1989). The results of the survey on 947 consumer panel reveal that compatibility, system quality have positive impact on the formation of perceived ease of use. And it is also shown that the perceived ease of use, system quality, and compatibility have positive influence on perceived usefulness, but computer-efficacy has no effect on perceived usefulness. Meanwhile, it is confirmed that perceived usefulness and compatibility have positive effect on attitude toward internet shopping behavior, but perceived ease of use has no effect. In addition, perceived security and social norm, as opposed to the hypotheses, are shown to have no effect on internet shopping behavior. Lastly, applications and related limitations are discussed.

The Purpose of this study was to explore the generational conflicts around adult children's taking care of elderly parents and grandparents' caring for grand children. The results of this study were as follows. First, the child care responsibility of the parents' generation is much more intense than that of the parent care responsibility of the children's generation. Second, the norm of parent care has changed from being the responsibility of the eldest son to being the responsibility of all of the children, which had led to an increased probability of conflicts between the two generations due to the differences in expectation and reward. Third, the bilateralization of the kinship increases the responsibility of women in taking care of their families, which leads to an increase in conflict among women of different generations. Finally, the generational conflicts related to family care appear across different social classes.

Korean society is changing into multicultural society with increasing international marriage and immigrant influx. The increasing number of immigrants in Korean society suggests the necessity of social and economic integration of people with diverse cultural backgrounds. We study the entrepreneurial intention of multicultural immigrant. Cultural intelligence is closely related with sustainable value and belief to their eagerness in surviving of the 2nd country. Cultural intelligence is the individual's capability to function or manage effectively in different cultural settings or in multicultural settings. It is assumed that the cultural intelligence of multicultural immigrant might affect the entrepreneurial intention. Based on the theory of planned behavior, we set up the research model. 243 usable responses of multicultural immigrants in Korea were analyzed. Our findings suggest that cultural intelligence positively affected entrepreneurial intention by affecting subjective norm and perceived behavior control. This study contributed the study of the entrepreneurial intention and multicultural immigrant.

The current research brings the spotlight onto customer Gapjil toward service employees. In an attempt to understand what brings Gapjil, the present article investigates the intertwined effects of perceived economic mobility (PEM), self-other referent priming (SORP), and temporal focus on Gapjil. Study 1 shows that PEM increases Gapjil among self-referent primed people, but not among other-referent primed people. Study 2 examining the role of temporal focus (present vs. future) reveals that the effect found in study 1 is replicated in the present focus, but the effect is reversed in the future focus. We explain this dynamic pattern of the 3-way interaction effect with a relative gratification and a motivation to attune the self to the perceived norm of the high class. We also discuss how to create a social atmosphere to lessen Gapjil in public and corporate communication strategies.

The Purpose of this study was to examine the relationship social capital between self efficacy, and the elderly in participated employment or not. The subjects were 340 elderly people in K, S, Y City in Jeonnam. The statistics used for data analysi were reliability, frequency, percentage, mean, standard deviation, one way ANOVA, correlation and multiple Regression. The results of this study were as follows ; First, the degree of social capital of the elderly in participated employment was 86.5(median value 81), while the degree of social capital who did not participated was 79.7. And the degrees of elderly's self efficacy was 43.2, those data showed higher than median. while the degree of self efficacy who did not participated was 39.1. Second, The elderly's social capital level in participated employment were significantly according to residence, religion, living state, economic state, frequency of employment, health state, spouse, monthly income, and the elderly's self efficacy level in participated employment were significantly according to social capital, economic state, monthly income, spouse, health state, living state, education, religion, frequency of employment, Third, participation on the employment for elderly' social capital was the highest correlation variable in self efficacy. Fourth, The variables that affect the elderly's social capital level were economic state, health state, spouse, religion, which explained about 13% of the total variance. And the variables that affect elderly's self efficacy level norm, economic state, network, participation, residence, health state, trust, age, spouse, which explained about 34% of the total variance.

This study examined the effects of social capital on psychological identity and practical wellbeing for the Korean baby boom generation. To achieve this, an empirical survey was carried out on baby boomers who use elderly welfare centers and cultural centers living in D City. The overall research results showed that trust (t=6.893, p<.05), participation (t=5.157, p<.05), network (t=8.093, p<.05), and norm and reciprocity (t=4.787, p<.05), as sub-factors of social capital for baby boomers, had a significant effect on their practical wellbeing. Psychological identity was moderated (t=2.023, p<.05) in the effect of trust on practical wellbeing, adopting the hypothesis. This means that the social ties and the strong trust relationship between family members and relatives, which built up amid rapid economic growth, work with positive expectations of social capital and have a major effect on practical wellbeing. Moreover, practical welling also rated high, along with the high trust relationship and psychological identity. Consequently, various exchange programs and group and volunteer activity programs for baby boomers should be established to decrease their psychological identity due to the loss of social roles. Moreover, the decline of activities at a time of retirement can slow practical wellbeing.

Recently, as the role of science and technology in social domain is more increased and the creative economy becomes a important matter in national development strategy, it is necessary that the improvement of legal system on science and technology for efficiently responding to paradigm shift into Innovation driven science and technology policy. Especially, The Framework Act On Science And Technology as a general and basic norm on science and technology policy is necessary to revise in systematic and substantial aspect in order to correspond with changed environment and current of the times. The Framework Act On Science And Technology was established in 2001 and revised several times, but substantial amendment reflecting the political facts as the need to demand was insufficient because it was revised only related with restructuring the government organization and changing the S&T Policy Coordinating Committee system. And therefore, this paper aims to review the problems and complementary factors and suggest the improvement draft on The Framework Act On Science And Technology. According to study, the revision methodologies are following : first, the Chapter and Paragraph of the law should be restructured to improve the systemicity, next the comprehensiveness, effectiveness, connections with related special laws and compatibility of the law should be complemented by adding the new provision or amending the inadequate provision to improve the position and function as a general and basic norm.

The purpose of this study was to examine the level of human rights sensitivity and the types of perception in regards to the human rights of college students to enhance their human rights sensitivity. The study methodology included a t-test and variance analysis for the level of human rights sensitivity, and a Q-factor analysis for the perception types of human rights. As a result of examining whether there is a difference in human right sensitivity, it was found that female students were higher than male students, and juniors and seniors were higher than freshmen and sophomores. The human rights sensitivity of the students in the social and science department were the highest, and those who had volunteer experiences were more susceptible to human rights than those who did not. Students who registered for organ donation were higher than those who did not, and those who received human rights education showed higher human rights susceptibility than those who did not. Four perception types of human rights were analyzed 'universal social moralists', those who have an idealistic mindset and make decisions based on moral standards, 'practical realists', those who have no intention of breaking out of the social norm and who do not want to take any risks for human rights, 'social system advocates', those who have a clear understanding of the basic human rights concept, but don't think that they should break the rules of society for the sake of individual rights, and 'social contracts advocates', those who are willing to bend the rules of society for human rights, but not to the extent of ruining relationships. These study results are expected to contribute to the possibility of the social viewpoint that human rights sensitivity can be developed in the context of social experience as well as perception.
