  • Korean government has initiated integrated-energy business (IEB) in Mokdong for energy conservation in 1983. Since then, IEB has been steadily expanding. This paper attempts to apply input-output(I-O) analysis to examine the economic effects of IEB. A static I-O framework is employed, focusing on three topics in its application: the impact of the investment of IEB on the production of other sectors and the inter-industry linkage effect; supply shortage effects of the IEB ; and the impact of the rise in IEB rate on prices of other products. The paper pays closer attention to IEB sector by taking the sector as exogenous and then investigating its economic impacts. The results can be widely utilized in decision-making about IEB policy.

  • Knowledge transfer occurs in various social contexts, within individuals and groups, and, thus, is closely linked to social networks in an organization. This paper applies social network theory and social identity theory to knowledge management area. The subject of this study was organization members who transfer their knowledge. 296 questionnaires were collected and analyzed. The results are as follows. First, in-group and out-group's tie strength have a significant effect on knowledge transfer. Second, the study shows that the knowledge transfer influences positively individual, team and organizational performance. Lastly, the study verifies that the applied knowledge has a moderating effect on the relationship of the in-group's tie strength and knowledge transfer.

  • The purpose of this study was to investigate the trait cortical arousal level, measured by extraversion-introversion, in schizophrenics. Subjects in this study were 231 (chronic schizophrenics=78, acute schizophrenics=62, and normal persons=91). All subjects were asked to respond to extraversion-introversion subtest scale in the korean EPQ(Korean Version Eysenck Personality Questionnaire). Collected data were analyzed by using the t-test and one-way analysis of variance. Results were as follows : 1) Trait cortical arousal level of chronic schizophrenics, which was measured by extraversion-introversion subtest scale in the Korean EPQ, was statistically higher than that of acute schizophrenics and normals. 2) Acute schizophrenics and normals were not significantly different in the trait cortical arousal level. However, the trait cortical arousal level of chronic schizophrenics was higher than that of acute schizophrenics. Therefore, it may state that the trait cortical arousal level of schizophrenics is getting higher when schizophrenic symptoms become more chronic.

  • This study was conducted to investigate the effects of neurofeedback (NFB) on attention in college students with ADHD. Participants were 27 university students, 10 in an NFB training group (experiment group), eight in a CBT group (comparison group) and nine in a no-treatment group. The score of CAARS-K decreased significantly in both the NFB group and the CBT group relative to the no-treatment group. Additionally, the score of the digit span test increased significantly in the NFB group, CBT, and no-treatment group, and the scores of these three groups differed significantly. Moreover, significant changes in EEG were found in the NFB Group, while the CBT group showed no significant changes in EEG. The significant change in EEG implies that NFB training improved the stability of brain function on the cerebral neurological level. The effects of improved attention remained after 5 weeks in both the NFB and CBT group. Finally, implications, limitations, and suggestions for future studies were discussed.

  • 영화 로보캅, 아이언맨 등에 등장하는 외골격기구(exoskeleton)는 이제 더 이상 먼 미래의 얘기도 아니고 딴 나라 얘기도 아니다. 외골격기구 중 특히 하지외골격기구는 Baytheon Sarcos, Berkley Bionics, Exohiker, Bleex, HAL5 등의 이름으로 버클리, 스탠퍼드 등 해외 우수 연구집단에서 이미 개발을 성공하였고 상용화를 앞두고 있다. 늦은 감은 있지만 국내에서도 재활의료용, 군수용 하지외골격기구 연구가 진행되고 있다. 본 저자는 최근 기존연구와 다른 접근방식으로 고민을 시작하였고 본 연구팀이 상표출원한 $PLE^{TM}$, $LeSATA^{TM}$의 개발을 서두르고 있다. 이 글을 통해 그간의 고민들을 간략히 털어놓을까 한다.

  • The purpose of this study was to find differences in evaluation criteria and to find differences in preferred images based on benefits segmented groups of jeans products consumers. Male and female Korean university students participated in the study. Quota sampling method was used to collect the data based on gender and a residential area of the respondents. Data from 492 questionnaires were used in the analysis. Factor analysis, Cronbach's alpha coefficient, cluster analysis, one-way ANOVA, and post-hoc test were conducted. As a result, respondents who seek multi-benefits considered aesthetic criteria(e.g., color, style, design, fit) and quality performance criteria(e.g., durability, ease of care, contractibility, flexibility) more importantly when evaluating and purchasing jeans products. Respondents who seek brand name considered extrinsic criteria(e.g., brand reputation, status symbol, country of origin, fashionability) more importantly than respondents who seek economic efciency. Respondents who seek multi-benefits such as attractiveness, fashion, individuality, and utility tend to prefer all the images: individual image, active image, sexual image, sophisticated image, and simple image when wearing jeans products. Respondents who seek fashion are likely to prefer individual image, and respondents who seek brand name more prefer both individual image and polished image. Mean while, respondents who seek economical efficiency less prefer sexual image and polished image.

  • Apologies are used with increasing frequency for mending damaged relations between groups after intergroup conflict. Past research revealed that members of a perpetrator group may engage in (animalistic) dehumanization of victim group members to cope with guilt and responsibility associated with the ingroup's past wrongdoing. We hypothesized that ingroup's apology would relieve perpetrator group members of the moral threat, and therefore would make them perceive more humanness in the victim group members. The study was conducted in the context of South Korea's alleged atrocities against Vietnamese civilians during its military involvement in the Vietnam War. Korean participants read an article on the incidents with Korean government's issuance of an official apology manipulated, and reported their thoughts on the incidents and perceptions of Vietnamese people including their humanness. Contrary to our prediction, apology further enhanced dehumanization of Vietnamese people, even while it also decreased dehumanization through heightened feelings of relief. This study documents a seemingly ironic effect of intergroup apology, and calls for a more careful examination of the consequences of apology before recommending it as a viable strategy for alleviating intergroup tensions.

  • The purpose of this study is to examine whether the effect of service satisfaction regarding the accessibility of child care services varies between dual-earner and single-earner families. In particular, we conducted the analysis by dividing the service accessibility into sub-areas. The study sample consisted of 267 parents living in Seoul and Gyeonggi region. As a result of the analysis, accommodation in use time and affordability influenced satisfaction in the single-earner families, and information acquisition and acceptability in the dual-earner families. For single-earner families, the more convenient the use time of the childcare institution and the less the service cost burden, the higher the satisfaction. The dual-earner families had higher satisfaction levels if it was easier to obtain information about the childcare centers and weaker the religious characteristics of the childcare centers. Based on the research results, it is necessary to differentiate the burden of cost and provide more flexible operation of childcare service operating hours. In addition, it is necessary to devise a policy method to increase the transparency of information to childcare institutions.

  • The purpose of this study is to investigate the effects of indoor and outdoor exercise environments on bone mineral density and body composition in old women. A total of 26 old women were randomly divided into two groups: an indoor exercise group (IE, n=13) and an outdoor exercise group (OE, n=13). The exercise groups performed moderate exercise (HR max 50~70%; RPE 11-15) three times a week for 60 minutes over 20 weeks. After exercise training, bone mineral density was significantly improved in the OE group as compared with the IE group. Body fat mass was significantly decreased in the IE group. Weight, lean body mass, and body fat mass were significantly decreased in the OE group. Body mass index was significantly decreased in the outdoor exercise group as compared to the IE group. Our findings show that a 20-week program of outdoor exercise training improves bone mineral density and body composition in old women. As mentioned above, it has been found that engaging in an outdoor exercise program for 20 weeks has a positive effect on bone mineral density and body composition in old women. In conclusion, engaging in the outdoor exercise program, including aerobic and resistance exercises, for 20 weeks improved bone mineral density and inhibited bone loss in old women and had a positive influence on vitamin D levels, thereby potentially lowering the risk of osteoporosis.

  • This study attempts to review and evaluate the sociological engagement and media practices of an eminent French sociologist Pierre Bourdieu. In the first part of the paper, I presented some characteristics of Bourdieu's view on the sociological engagement. In the second part, I also examined Bourdieu's alternative media strategies(ARSS, Liber, Raisons d'agir) which were designed to intervene effectively in the academy and public sphere of French society. For Bourdieu, the sociological engagement can be conceived and legitimized as follows: first, the talents of the ensemble of 'specific intellectuals' in Foucaldian sense should be combined to constitute a kind of 'large collective of intellectuals' Second, this 'collective of intellectuals' should make 'corporatist' efforts to improve the autonomy of the 'field of cultural production', which is the indispensable condition for the conquest of 'the universal' Bourdieu tried to realize his logic of sociological engagement through all his intellectual works, media activities and political intervention. In appreciating positively the consistency and originality of Bourdieu's theory and practice of engagement, I proposed to reconsider some limits of his 'modern' politics - enlightenment, science, collectivity - in today's 'postmodern condition'.
