3 차원 콘텐트를 이용한 물리기반 시뮬레이션은 최근 컴퓨터 그래픽스 분야에서 가장 활발히 연구되는 연구 중 하나이다. 이와 더불어 이러한 기술들과 사용자간의 몰입감을 증가시키는 상호작용 기술 역시 계속하여 증가하는 추세이다. 본 연구는 이러한 추세에 발맞추어 물리기반 형상변형 기술의 몰입감을 증가시키기 위한 상호작용 방법을 제안한다. 제안된 방법에서는 3 차원 객체와 사용자와의 효율적인 상호작용을 위해서 시스템을 증강현실 환경에서 구현하였다. 증강현실을 이용한 시스템의 제약조건은 실시간 계산이다. 때문에, 제안된 시스템은 RBF(Radial Basis Function) [1] 와 LSM (Lattice Shape Matching) [2, 3] 방법을 조합하여 물리기반 상호작용 기술을 완성 하였고 실험을 통해 실시간 계산을 확인하였다. 또한, 3 차원 객체가 충돌하여 변형이 일어날 때 감각형 객체 (Tangible object)에 진동을 주어 물리기반 형상변형의 사용자 상호작용에 관한 몰입감을 증가시켰다.

TV home shopping maintains annual growth in the midst of harsh competition by numerous fashion retail channels. This study investigated the dimensions of service quality of TV home shopping for fashion products as well as the effect of service quality on relationship commitment and customer loyalty. Questionnaires were distributed to consumers in their 20s to 40s who purchased fashion products via TV home shopping in the past 6 months. A total of 240 questionnaires were put into the analysis. The results are as follows. First, four dimensions of service quality of TV home shopping were found: convenience, economy, entertainment, and information seeking. Relationship commitment had two dimensions of affective commitment and calculative commitment. Second, the service quality of TV home shopping affected customer loyalty through a relationship commitment. The predictors of affective commitment were entertainment, economy, and information seeking; in addition, those of calculative commitment were economy and entertainment. Third, both affective commitment and calculative commitment predicted customer loyalty to TV home shopping. The affective commitment had more predictive power. The findings show that the service quality of TV home shopping did not directly affect customer loyalty, but they had influence through relationship commitment variables. Entertainment and economy were the most powerful predictors among service quality dimensions.

This study examines the effects of store environment on consumer commitment to department stores and the differences among department stores. A self-administered questionnaire was developed based on existing scales in the literature and the result of qualitative research. The survey was conducted on 500 female consumers in their 20s to 40s in Seoul, Incheon and Gyeonggi areas in Korea. Data were analyzed using descriptive statistics, factor analysis, ANOVA, and regression analysis via SPSS Win 16.0. The results were as follows: First, three department stores revealed statistically significant differences in the diversity of facilities, store atmosphere, locational convenience and policy. Second, affective commitment to department stores was affected by salesperson service, policy, diversity of facilities, product assortment, store atmosphere and locational convenience. Calculative commitment in department stores was affected by policy, diversity of facilities, store atmosphere and locational convenience. There were also significant differences on store environmental factors that influence affective commitment and calculative commitment among department stores.

In this paper, we propose a PC based immersive virtual environment system with expandability and compatibility in contrary to existing immersive virtual environment(IVE) systems which have been implemented by supercomputer or special computing system. The application based on commercial personal compute may have two major advantage: one is variety of resources, the other is user-friendly interface. This system intends to offer easy contact to IVE system, realistic images, and convenience. Also, the system can handle various virtual reality at real-time and make it easier to interface existing complicated haptic device. Geometric techniques are adopted to calculate and visualize the physical phenomenon to speed up the computing time. The proposed implementation method of PC based immersive virtual environment system is implemented to the example in which user move around inside of and interact with virtual office environment wearing data glove, behavior recognition devices, and HMD.

Prior research has investigated different effects of brand performance information such as premium price information and market share information on brand equity components - quality perception and brand preference. It was shown that the differential effects of brand performance information could depend on product-related variables like product category concept and quality variation in the product category. In this study, we conducted an experiment to find out how personal characteristics such as self-construal, price perception and brand commitment could influence the effects of different types of brand performance information. The results show that individuals who have independent self-construal, favorable price perception and emotional commitment with the brand develop more favorable evaluation of the premium price performance information resulting in more positive evaluations of the brand. However, individuals who have interdependent self-construal, unfavorable price perception and cognitive commitment with the brand develop more favorable evaluation of the market share performance information resulting in more positive evaluations of the brand. We discuss the theoretical and practical implications of this study and its limitations, along with future research interests.

As the society changes, the Private Security has developed highly in a short time. However, it has brought about various problems. The best urgent problem of those problems is the wage problem. This study is examining into the difference with the wage satisfaction and devotion to organization, and analyzing influence that wage satisfaction has on devotion to organization. According to this research, the first, women appeared higher numerical value than men in satisfaction with a wage level, wage disparity, wage system and the welfare system and the highest age group is over 26 year-old. While the college graduates appeared high satisfaction with a wage level and wage disparity, the university graduates is high satisfaction with wage system and the welfare. This shows that as the scholarship is high, they think they must be getting wages higher and higher as their work result or produce. The second, in devotion to his(her) organization, the men is higher than the women. The third, the men show the high emotional devotion because the men devote to his work on his own initiative while the women show the high continuos service devotion because they are passively. The fourth, over the 26-year old group appeared high level in devotion to his(her) organization, the university graduate group appeared high level both the emotional devotion and the continuous service devotion. The long-term employed person showed the satisfaction with job position, pay grade, and career and also appeared high in devotion to his(her) organization. The fifth, as the scholarship is low, they were concerned about a wage level and wage disparity but, as the scholarship is high, they were concerned about the wage system and the welfare. The wage satisfaction has influence on the scholarship, job position and career therefore, the long-term employed persons showed high wage satisfaction and devotion to his(her) organization. In conclusion, for the development of Private Security and high devotion to organization, the wage level of private security guards must be systematize and the quality of the welfare must be improved. And the many factors about the wage and welfare must be studied and analyzed to occupy as one of the skill lists through the educational-industrial collaboration.

With the recent development of virtual reality, it has been actively investigated to develop user interfaces for immersive interaction. Immersive user interfaces improve the efficiency and the capability of information processing in the virtual environment providing various services, and provide effective interaction in the field of ubiquitous and mobile computing. In this paper, we propose an virtual reality platform "My Workspace" which renders an 3D virtual workspace by using an immersive user interface. We develop an interface that integrates an optical see-through head-mounted display, a Wii remote controller, and a helmet with infrared LEDs. It estimates the user's gaze direction in terms of horizontal and vertical angles based on the model of head movements. My Workspace expands the current 2D workspace based on monitors into the layered 3D workspace, and renders a part of 3D virtual workspace corresponding to the gaze direction. The user can arrange various tasks on the virtual workspace and switch each task by moving his head. In this paper, we will also verify the performance of the immersive user interface as well as its usefulness with the usability test.
