In order to implement the real-time enterprise (RTE) and smart work effectively, many companies have introduced a mobile office. A mobile office improves employee productivity and increases ability to respond to business opportunities by helping employee manage their business anytime and anywhere. However, it also raises the user's stress level. We conducted in-depth interviews with users to assess user's perception of a mobile office according to Saaty's BOCR model. Based on the results of the interviews, we set variables affecting user's perception of the mobile office using factor analysis. This study revealed that support for real-time business, support for communication and collaboration, and information processing quality were positively related to continuous intention to use mobile office. Further study demonstrated that three variables have mediating effect between the psychological stress and continuous intention to use. This result implies that the system quality and function are the key elements of mobile office and may contribute to the continuous use.

In this study, we analyzed the old`s characteristics for depth perception in comparison with the young`s as a basic study for universal design in field of products or facilities. Twenty three of the old and twenty two of the young had participated and the depth perception apparatus was used in this experiment. Gender, viewing distance, and age were considered as factors and the differences of depth perception were analyzed for each experimental condition. In the result, a significant difference was not detected on gender, but significant differences were detected on age and viewing distance. That is, we can see that the old is remarkably worse than the young on depth perception task. Therefore, it means that these characteristics have to be absolutely considered in user interface design to improve the old`s accessibility for products or facilities.

This study was conducted to analyze Korean companie's perception in IT investment cost-benefit analysis(CBA), and to see if various user group's perception is different. Literature was reviewed to classify and define variables in IT CBA, and questionnaire was distributed to CEOs, CIOs, IT managers, and general managers in Korean companies. Respondent's priority ranking in IT CBA was shown to be tangible benefit, direct cost/intangible benefit, and indirect cost/risk. Data analysis showed that Korean companie's actual practice in CBA was generally aligned with their perception. User group's(Executives vs. mangers, and IT managers vs. general managers) perception was not shown to be statistically different. Survey result also showed that IT CBA was not well practiced in the companies although respondents perceive the analysis very important. These findings suggest that more education and practical experience is needed for Korean companies to perform IT CBA.

본고의 연구는 SNG 서비스의 이용에 있어 사용자간의 약한 유대관계의 힘과 감성적 상호작용이 만족과 구전에 이르는 경로모형을 검증하고, SNS가 지닌 감성적 실명효과가 서비스 확산에 미치는 영향 및 정책적 함의를 확인하고자 하였다, 연구결과 모바일 SNG 사용자의 약한 유대관계의 힘이 사용자간의 감성적 상호작용성과 만족에 영향을 미치는 것으로 확인되었다. 또한 SNS의 감성적 실명효과로 인해 사용자들은 신뢰관계가 형성되어 약한 유대관계임에도 불구하고 감성적인 상호작용을 하는 것으로 판단된다. 그리고 구전에 영향을 미치는 변인은 선행한 유대관계나 상호작용이 아닌 만족인 것으로 나타났다. 선행변인들이 실명SNS 효과가 있지만 궁극적으로 서비스를 구전하게 하는 것은 만족이라는 요소에 의해 좌우된다는 것이다. 따라서 서비스 제공사업자들은 구전으로 전달되는 서비스의 만족을 이끌어 낼 수 있도록 고객 중심의 정책으로 SNG 서비스를 개선시키는 등의 실무적 제언이 가능 할 것으로 기대된다.

Fuzzy Neural Network (FNN) is a compulsory element in a voice-controlled machine due to its inherent capability of interpreting imprecise natural language commands. To control such a machine, user's perception of imprecise words is very important because the words' meaning is highly subjective. This paper presents a voice based controller centered on an adaptable FNN to capture the user's perception of imprecise words. Conversational interface of the machine facilitates the learning through interaction. The system consists of a dialog manager (DM), the conversational interface, a Knowledge base, which absorbs user's perception and acts as a replica of human understanding of imprecise words,...

The Affordance, discussed in the theory of ecological perception of environmental psychology, is the concept of perception that deals with inter-relationship between environment and human. It is a theory seeking for gradual evolution, with the change of user experience behavior and the space, by getting feed-backs from the analysis of perception of characteristics of 3-dimensional space and the user as moving entity. Although there has been many attempts to define the Affordance and apply its concept to the architecture, now there's a need to identify the Affordance in the real architectural space, represent Affordance of space and the user inter-relationship in the architecture and apply its design specifically, Thus, the purpose of this study is to present the methodology of applying Affordance in architectural space design by identifying the Affordance of space concept of human experience behavior in the architectural space and analyze its recognition process.

대규모 군중이 등장하는 장면에서 군중을 구성하는 수많은 캐릭터들을 신속하고 편리하게 생성하기 위한 방법론으로서 캐릭터 모델과 모션의 복제가 제시되고 있다. McDonnell[1] 등은 보다 현실적이고 복잡한 군중을 생성하기 위하여 사람들이 복제를 인지하는데 영향을 미치는 요소들이 무엇이 있는지 실험하였다. 카메라가 고정된 상황에서 화면에 일정하게 배치된 군중들을 복제하는 기준으로서 외형과 모션의 2가지 요소를 제시하고, 사용자가 모션보다 외형의 변화에 민감하게 반응한다는 결과를 보였다. 본 논문에서는 McDonnell[1]의 연구를 확장하여 실시간 게임 환경에서의 캐릭터 복제와 사용자 인지 간의 상관관계를 연구한다. 시점의 변화가 자유롭고 여러 방향으로 이동하는 군중이 있는 역동적인 게임 환경에서 사용자가 다수의 캐릭터 복제쌍을 어떻게 인지하는지에 초점을 맞춘다. 특히, 게임 캐릭터의 필수 요소인 아이템에 다양한 형태와 색상 및 패턴 요소를 적용하여 아이템을 통한 캐릭터의 다양화가 가능함을 보이고, 캐릭터 복제쌍의 이동 방향과 상대적인 거리에 따라 변화하는 사용자의 인지를 실험하여 사용자가 허용 가능한 캐릭터의 복제 범위를 제시한다.
