In this paper, we propose a level of contexts such as low level and high level contexts, and its criteria of categorization are the existence of interaction and composite process done by the inference mechanism. When there is no matching high level service for the associated high level context, this context is described as meaningless. If the services cannot be provided with the entities by the system, this situational information is of little consequence. To provide services with the entities, we propose "community computing" architectural concept which provide the high level service to a group of agents in a community, and can be managed by the service scenario

This paper proposes authority delegation for secure social community creation and mutual authentication scheme between the community members using proxy signature in community-based ubiquitous networks. In community-based ubiquitous network, User's context-awareness information is collected and used to provide context-awareness network service and application service for someone who need it. For the many reason, i.e. study, game, information sharing, business and conference, social community could be created by members of a social group. However, in community-based ubiquitous network, this kind of the context-awareness information could be abused and created by a malicious nodes for attack the community. Also, forgery community could be built up to attack the community members. The proposed scheme using the proxy signature provides a mutual authentication and secure secret key exchange between community members, and supports secure authority delegation that can creates social community. Also, when delegation of signing authority and mutual authentication, this scheme reduces total computation time compared to the RSA signature scheme.

New city development policy caused many effects such as destruction of nature and area native culture extinction through fast development within short period. The architectural context is remains by post-modern most difficult problem had left to architects. We need to find the design method that communicate and contacts character of place, cultural context through the actual project. In this study, we propose the method of aspect of compose space and design elements to succeed the cultural place and context, desirable development through the design proposal for Dochon welfare center. In Dochon area, there is no original character of the place because of indiscreet development. Dochon synthesis society welfare facilities is openable to people by space that nature and human contacts and accomplishes relation, Made efforts to do so that can do part that causes human's ripple effect of contact with human and accomplishes traffic and recovers identity of Dochon area at the same time recovery of community consciousness.

Objectives: This paper aims to identify the dimensions of community capacity in a public residence lease apartment complex in Seoul as a case study, and discusses their application to community health promotion. Methods: The research team performed a focus group interview and a brief survey with resident committee representatives to explore community context and to identify the dimensions of community capacity and their order of priority. Results: We identified many groups with different senses of community and various dynamics in the community. Seven dimensions of community capacity were identified. However, there are different developmental stages among them. Also there are some influences with the different directions in a dimension, e.g. leadership and citizen participation. Conclusions: This study illustrated the identification of the dimensions of community capacity focused on the perspective and recognition of the community and community member, as an effort to understand community capacity in domestic community health promotion context.

My purpose in this paper is to construct what I call "the space of hope" for the individual′s unfettered interpretation of the world and examine its ethical and political potential. 1 discuss the network of context to define the nature and scope of the space and also suggest that the individual′s interpretation of the world should be deemed a form of ethical practice or commitment. 1 would like to add that the term context, which refers, among other things, to the organic and dynamic relationship between individual and community, is meant to be strategic: it presupposes productive malleability, even slipperiness, in order to destabilize the institutional or ideological hierarchy between center and margin and enhance the individual′s self-conscious negotiation with his or her own community. It is my contention that every act of interpretation is always under some kind of contextual pressure and that the individual is able, in turn, to define and construct the context. This interaction represents a way to guard against the inimical force of totalization in the realms of theory and practice and can be summed up, that is, tentatively and strategically, in the idea of positionality.

The purpose of this study is to identify the factors determining users' acceptance of individualized virtual community. While there has been considerable research on the Technology Acceptance Model (TAM) that has predicted whether individuals will accept and voluntarily use information systems, limitations of the TAM include the omission of an important characteristics of individual construct in the context of individualized community. Based on literature relating to the theory of reasoned action (TRA), the theory of planned behavior (TPB) and the TAM, this study extends the applicability of the TAM in a individualized community context, by adding characteristics of individual-based construct ("subjective norm", "self-efficacy", "self-presentation" and "sharing information to exchange various information") to the model. Analysis was conducted on using the structural equation modeling approach. The result supports the extended TAM in predicting users' intentions to using personalized community. Several implications for IT/IS acceptance research and individualized community service management practices are discussed.

This study is an exploratory case study of a humanity community building process in a rural area context, particularly in the villages of Eoro-ri, Chilgok-gun, and Gyeongsangbuk-do. Chilgok-Gun has institutionalized support systems for a humanity community building, and has implemented some programs for four years. This article uses a qualitative approach to analyze the process of community buildings, such as in-depth interviews and observations. The analysis is based on the process of discovering, vitalization, and self-governing for community buildings, and give some implications for future community buildings in a rural area context as follows. First, the village leader constantly needs to be cultivated. The village leader is not a simple representative of the village. He constantly needs to make efforts to communicate with the villagers. Second, learning through constant self-reflection is necessary for the villagers. It is important to make community programs and residents' small meetings to facilitate reflection. In community buildings, the process of communication and consultation for villagers is more important. The process that creates a new value of the village in the learning process takes place. Third, talented village people who can develop the village should be educated. This is a virtuous circle for Village Development. Aging in rural areas has been deepening, which will affect the future of local communities that can meet in accordance with various crises and responses. There is a need for complex research on sustainable ways to reinvent itself as a community.

One of critical issues in the housing area is what strategies should be adopted for revitalizing contemporary communities in housing complex. It is expected that those strategies could encourage neighbourship and recover the existing community spaces. Based on the assumption that contemporary communities might have different characteristics from those of the traditional communities and spaces, this research aims to explore the possibility of new communities in a current context. With the development of the information communication technologies (ICT) and hardware systems, the environment would be capable of anticipating people's needs and then provide them with customization options to tailor the environment to their requirements. By incorporating the 'smart' paradigm, this paper introduces the concept of a smart community and space with the potential of mobile Augmented Reality(AR) as alternative strategies for activating the communities. The residents believe that existing common spaces need to be extendable and augmented by combining new technologies. The smart communities and spaces are expected to extend people's interaction to virtual world in aj real context, further combined with social network, it enables sustainable relationships among residents, contributina to a new type of community.

This paper proposed a session key exchange and authentication scheme on non-interactive key distribution algorithm using a community member's ID in ubiquitous networks. In ubiquitous network environment, User's context-awareness information is collected and used to provide a context-awareness service for someone who need it. However, in ubiquitous network environment, this kind of the Context-awareness information could be abused by a malicious nodes. The proposed scheme using the community member ID provides a session key exchange and mutual authentication between community members, and supports secure data communication. Also, when exchanging the session key and authenticating each other, this scheme reduces communication overhead and authentication delay compared to the AAA server scheme.
