This study considers both causal and control factors for explaining both contact and distribution of sexually explicit material and tests their interaction effects for examining buffering effects of control factors in causal process. This study examines the effect of low self-control, differential association with peers and patriarchy family environmental factor as causal factors. It also considers three control factors such as morality. legal punishment, and lack of opportunity and test interaction effect between causal and control factors in both contact and distribution cases. Using data from college students in Seoul, results show that the effects of all causal factors are significant in both contact and distribution of sexually explicit material and the effect of differential association is the most significant. However, their interaction effects between causal and control factors are different across contact and distribution cases. In the contact case, all interaction effects are not significant. It means that causal factors have independent effects and control factors have no buffering effects. However, in the distribution case, the interaction effects between low self-control and morality, between differential association and morality, between patriarchy family and punishment, and between patriarchy family and lack of opportunity are significant. Empirical implications are discussed.

This study developed a method which recognizes emotional interactions from the social distance by a beacon wearable device. The recognized interaction was evaluated by comparing with the cardiovascular synchrony from photoplethysmogram (PPG). The interaction was recognized when social distance was maintained for a certain period of time. The cardiovascular synchrony was estimated by correlation anaysis between beat per minute (BPM) from PPG. The maintenance time was determined by Mann-Whitney U test between the cardiovascular synchrony of interaction and non-interaction groups. Fifteen groups (2 persons per a group) participated in the experiment and they were asked to wear the beacon and PPG wearable devices in daily life. Experimental results showed that the interaction groups had more higher cardiovascular synchrony than non-interaction groups and the significant interaction time was determined to be 11 seconds (p=.045). Consequently, the real-time measurement and evaluation of the social network in real space was expected to be improved.

This study investigated the role of organizational communication, culture and trust as a moderator of the organizational performance(the growth of production and quality improvement) and job satisfaction. Using data collected from 248 workers at 128 establishments in Changwon industrial complex, morderated regression analyses explored the proposed model. As a result, communication activity and organizational trust was found negatively to moderate the relationship between job satisfaction and quality improvement/the growth of production. And organizational culture was found positively to moderate the relationship between satisfaction and quality improvement. Implications of these findings were discussed.

지하수와 지표수의 상호작용은 혼합대(hyporheic zone)와 홍수터 물수지에도 영향을 끼치며 특히 생물학적인 측면에서 중요한 역할을 하는 혼합대의 경우 유역 전반에 걸쳐 불균일한 분포를 나타낸다. 그런데 기존하천-대수층 상호작용에 대한 연구는 하천변에 근접한 지역의 대한 연구로 국한되어 있다. 따라서 단순히 하천-대수층간 상호작용의 영향을 하천변에 국한시키는 것이 아니라 유역규모로 확장하여 유역단위 지표수-지하수 상호작용에 대한 심도 있는 해석을 해야만 보다 정확한 지표수-지하수의 연계운영이 가능하다. 본 연구에서는 유역단위 지표수-지하수 상호작용을 해석하기 위해 완전연동형 SWAT-MODFLOW를 이용하여 하천과 대수층의 상호작용의 강도를 하천 구간별로 찾아내고 그 교환의 공간적 범위도 추정함으로써 혼합대연구를 위한 실증을 수행하고자 한다. 유역 단위의 지표수-지하수 상호작용을 해석하기 위하여 SWAT-MODFLOW모형을 안양천 중상류 유역에 적용시킨 결과 하천과 대수층간에 상호작용의 영향범위와 영향강도 등을 파악할 수 있었다. 하천-대수층 상호작용의 정밀분석을 통한 영향권 산정 및 혼합대의 발생범위 예측은 향후 하천복원 사업시 수생생태계 건강성 지표와 관련된 연구에 유용하게 활용될 수 있을 것이다.

Medical treatment for the aged has become an increasingly important concern as the aged population continues to grow. However, little research has been done on the issue. This study examines the roles of the expertise, convenience, and interaction of medical treatment systems applied by geriatric hospital. Medical treatment systems include oriental medicine, western medicine and integrated(oriental and western) medicine practices. The empirical results of the study are as follows. First, the relative impacts of the expertise, convenience and interaction on customer satisfaction are different depending upon the medical treatment systems. Second, convenience and interaction are shown to be more important factors in western medicine, while interaction is the case in oriental medicine. As for the integrated medicine practices, expertise is considered more important. Thus, it is necessary for the western medicine to make more efforts on interaction and convenience, while it is critical to enhance medical personnels' service quality in the oriental medicine. In the integrated medical treatment, actual and effective cooperation should be achieved to secure expertise. Third, the data demonstrate that customer satisfaction has a positive influence on relationship quality which, in turn, impacts on repurchase intention. Finally, relationship quality has a negative influence on intention to switch in the western medicine, whereas the impact of relationship quality is not significant in the oriental and integrated medicine practices.

Recently, in order to promote their marketing promotion, the entrepeneurs attach importance to many SNS services and execute it. The representative elements of the SNS service are interactivity, information offering. This study analyzes empirical effects on the SNS service depending on the Relationship Commitment and shows the strategies to enlarge the use frequency and the On-line Word-of-Mouth. The conclusion of this study shows that the Interactivity has a higher positive effects on Affective Commitment than those on information offering and Information offering has stronger positive effects on calculative commitment than interactivity. Also, these effects enlarge the high use frequency more than the low use frequency. This study also shows that the information offering affect the On-line Word-of-Mouth more positively than the Interactivity. And this study shows that SNS service affects the positive effects on the relationship commitment rather than the On-line Word-of-Mouth. Based on the results, the practical implications are offered.

This study empirically examined the structural relationships among components of interactivity, affective commitment, and components of brand equity in on-line brand community. Interactivity was conceptualized as 4 components such as mapping, personalization, responsiveness and connectedness. Components of brand equity include brand associations, brand awareness, and brand loyalty. Using a sample of 127 university students of on-line brand community members in Busan, we empirically examined the study model. The results of this study showed that components of interactivity except connectedness had a significant effect on affective commitment, which in turn, had a significant positive effect on brand associations, brand awareness and brand loyalty.

This paper presents a model for supporting the adaptive interaction between the computer and the learner. To design an adaptive interaction model, the strategy to support the adaptive interaction in the web-based educational system was established. And then. the necessary components for executing each strategy were selected. Also. the logical relations among the components were verified. To verify the effectiveness of the proposed adaptive interaction model, we applied the existing web-based courseware and the new courseware using the adaptive interaction models to two groups respectively, and then measured the performance of each group. Experimental results reveal that the adaptive interaction model actually has positive effects on the learning activities of the learner.

본 논문에서는 월드와이드웹에 기반한 학습자 중심의 통합 가상교육시스템 CyberClass를 설계하고 구현한 방법을 소개한다. 기존의 가상교육시스템은 학습자 중심의 상호작용 유형을 분석하여 이에 따른 적당한 상호작용 모델을 제시하지 않고 기능면에서의 사용도구 및 방법만을 제시함으로써 각 기능들이 자연스럽게 통합되지 못하였다. 따라서 전통적인 교육 방식인 강의실 수업에 참여한 학습자들이 가지는 현장감이나 친밀감에서 오는 커다란 교육적 이득을 제공하지 못하였다. 본 논문에서 개발한 가상교육시스템 CyberClass는 학습자 중심의 상호작용유형을 분석하고 이를 기반으로 상호작용모델을 제시한다. 그리고 제시된 모델에 기반하여 학습자와 교수, 학습자와 학습자 나아가 학습자와 가상교육시스템간의 상호작용에 기반한 시스템을 설계하였다. 따라서 학습자의 상호작용 모델에 기반함으로써 학습 참여도나 학습 능률의 향상을 기대할 수 있다. CyberClass는 학습자 중심의 상호작용을 위해 비동기공유 기공과 동기고유 기능을 모두 지원한다. 이들의 공유 기능들은 유기적으로 결합하고 직관적인 학습자 인터페이스를 제공함으로써 학습자에게 기능의 다양성에 따른 학습의 부담을 줄이고 자연스런 학습과정이 유도되도록 하였다.
