This research is about the methods in making computers understand the situation in regards to interaction between House and Human Behavior. In this paper, house is the ubiquitous house, as a future house, adopting ubiquitous computing presenting the interrelation of human and house - interior space, architecture, nature. And the Context Aware Model of ubiquitous house is proposed to embody the ubiquitous house. The research objective is to systematize the context in the ubiquitous house and suggest a theoretical basis to embody the ubiquitous house interacting between the House ud Human Behavior Especially, this paper focuses on the Context Aware Model based on FengShui-Theory(sp. YangTaek-Theory). The ubiquitous house is not what operates passively by human but a information-oriented house that can predict the situation and the living patterns of human. For a information-oriented house and informal living context at home, this paper uses FengShui-Theory whose central concern is the interrelation of human and nature. Through these concepts, this research will suggest how to systematize, control and manage the context at home. In the end, it is expected to offer a theoretical basis to embody the intelligent house and apply an environment design communicating between the computers and human.

In this paper, we defined constructivism and ontology theory and associate it in ubiquitous learning. The typical ubiquitous learning involving the Context Aware Intelligent system was presented. Also the Architecture for learning environment including the key idea and technical concept is being presented in this paper. Guided with these principles and with the advancement of information and communication technology the context-awareness based on Artificial intelligence for Location based Service for ubiquitous Learning was conceptualized.

A contemporary office space is changed by the transformation to an information-oriented society from an industrial society. A contemporary office space is recognized as an interactional space which is more of a mental and psychological space than a physical space. I studied the basic concept of an office space and the relationship of a social change and an office space on this study. I also studied the concept of an ubiquitous computing and the relationship of an ubiquitous computing and an office space. Through this study, we can establish the new concept of an office space to be applied to an ubiquitous concept. The ubiquitous concept of an office space will be brought into a new prototype of an office space, and then there is no more important to a physical place and time. The office space must be redesigned by an ubiquitous space nowadays.

The ubiquitous environment is to support people in their everyday life in an inconspicuous and unobtrusive way. This requires that information of the person and her preferences, liking, and habits are available in the ubiquitous system. In this paper, we propose the context aware system that can provide the tailored information service for user in ubiquitous computing environment. The system architecture is composed of 4 domain models that can perform some pre-defined tasks independently. And we suggest the hybrid algorithm combined with fuzzy and Bayesian network to reason what information is suitable for user environment. Finally, we apply to agent based RGA(Research Guide Assistant).

최근 U-City를 포함한 유비쿼터스 지능공간(Ubiquitous Smart Space)의 개발은 공간의 높은 부가가치 창출이 기대되나 과거에는 시도하지 않은 개발 방법론과 미래적 정보기술을 활용해야 하므로 위험성이 존재하며 이는 개발의 초기 단계에서 신중하게 검토되어야 한다. 더욱이 유비쿼터스 지능공간은 그 특성 상 여러 개의 유비쿼터스 컴퓨팅 기술들이 조합적으로 사용되어야 하는데 현재 존재하는 평가 혹은 선정 방법론들은 단일 기술 혹은 프로젝트에 대한 평가에 머물러 있다. 따라서 본 연구에서는 포트폴리오 이론 및 제약만족조건을 활용하여 위험성의 존재 및 유비쿼터스 기술을 포함한 복수정보기술을 선정하는 환경을 고려한 최적의 기술조합을 선정하는 방법론을 제안하고 이를 유비쿼터스 지능공간 개발에 적용하고자 한다. 본 연구 내용의 실용성을 입증하기 위해 현재 실제적으로 수행되고 있는 국가급 유비쿼터스 컴퓨팅 과제에서의 기술조합 사례에 적용해 보았다.

Ubiquitous computing is enhancing computer use by making many computers available throughout the physical environment without being noticed to the users. To facilitate successful adoption and diffusion of ubiquitous systems, it is important to find out the factors affecting their uses. Although researches related to ubiquitous computing have been vigorously conducted from the aspect of system and service provider, there have been very few studies that focus on the user's perspective. This study attempts to find out major factors which are dedicated to the development of ubiquitous systems and services and the relationships between these factors and user satisfaction factors. This study derived the specific factors that characterize ubiquitous services, such as ubiquity, contextual offer, user affinity, privacy, reliability, responsiveness, assurance, and empathy. We also considered service quality factors of ubiquitous services. Then these factors were combined with the Expectation Confirmation Theory (ECT) model and the path analysis was applied to find out the factors affecting user satisfaction and the intention to use the systems. The research findings indicate that ubiquity, contextual offer, privacy, reliability, and responsiveness affect the perceived usefulness. The perceived ease of use and confirmation were found to affect the perceived usefulness. The perceived usefulness, perceived ease of use, and confirmation fumed out to influence the satisfaction. It turned out that the result of this study on the relationship between the perceived usefulness and user satisfaction was identical with the findings in previous related ECT researches. We think this study makes two significant contributions to the development of ubiquitous services. First, this study provides basic implications for better ubiquitous services by considering important characteristics of ubiquitous systems as services. Second, this study also suggests important factors that need to be considered when ubiquitous service providers develop new ubiquitous services to improve user satisfaction and the intention to use the services.

In the ubiquitous computing environments. people usually carry multiple information technology devices with them. Personal device network (PDN) refers to the way how people connect multiple IT devices for their personal as well as professional purposes. Even though it has been Quite popular to construct the PDN in ubiquitous computing context, not much research has been conducted on how people actually connected multiple devices and what influences their methods of connection. In this paper we conducted a content analysis on community bulletin boards of IT devices and a contextual inquiry with expert users of PDN for investigating the configurations with which users connect multiple IT devices. Base on the results of two related studies, we identified three major types of PDN configurations, and key factors that influence the configurations of PDN. We conclude this research with guidelines to design a set of devices for each of the three configuration types.

With the sustainable development theory introduced, some planning factors, such as how to minimize bad effects on the environment and how to be more environmentally friendly, have been Integrated in planning the residential development. In addition, a new residential space concept, the ubiquitous home, arouse the interest of architects and residents. Although there have been many efforts to achieve the environment-friendly and convenient residence, the problem is that the environment-friendly architecture's many of the efforts have been primarily focused on the outside of the apartment units. Thus, the purpose of this study is to show possibilities of housing model not only being applied the environment-friendly construction concept to the inside of the apartment units, but also being integrated the ubiquitous home model inside.

Recent advances in mobile computing technologies and platform-independent information systems have enabled to realize a ubiquitous environment. Community computing has been developed as a useful tool for realizing collaborative services in a ubiquitous environment. In this paper, we present a formal model of a ubiquitous space that takes community concept into consideration and propose two management frameworks that prevent conflicts among communities. To demonstrate the validity of the proposed frameworks, an example for coordinating two communities is provided.
