The community consciousness used to be the core of the social capital in rural Korea, and there used to be a long tradition of mutual trust and cooperation in rural village community in Korea. However, recent trends in rapid urbanization or de-ruralization may affected community consciousness and social capital in rural society in Korea. The social capital has been existed in terms of mutual trust, commonly shared norms, and cooperative behavior in farm work and daily life of rural people. Commonly shared norms and networks have accelerated social effectiveness and promoted cooperative work as well as moral and spiritual aspects of rural society. Social capital in terms of community consciousness, participation of village work, visit and invitation of the neighborhood, and participation in various village group and networks were suveyed in JanggogRi, Jori Myun, Paju city, Gyeonggi province. The data collected from 65 persons, and the major findings of the study were as follow; The respondents responded that the community consciousness of de-rural area decreased in general with a few exception in the groups of alumni, family, religion and voluntary society. Social capital in terms of participation of village work, visiting the neighbors and voting increased slightly. Further research on social capital should be conducted to strengthen community consciousness, and various measures to increase the social capital should be adopted for livable community development.

Due to the rapid increase of the elderly population, promoted desire for recreational activities in old age and so emerging importance of Leisure welfare facilities for the elderly. Although Senior community centers playing an important role in old people leisure life are quantitative resources occupying majority of the Leisure welfare facilities for the elderly. there are many problems of managing programs, aging facilities, small spaces and so on. So, many facilities are used as simple meeting places of old people without solution about qualitative problem. Also, because of negative perceptions of people about Senior community center socially, desires of using Senior community center of old generation will decrease. In order to perfectly play a role of Leisure welfare facilities for the elderly, we need to review regulations about facility and program of Senior community center and suggest ways to resolve these problems. According to these necessity, Integration senior community centers appeared as a new concept. These centers compensate the physical defects through integrating small Senior community center. Through dividing function and service of senior welfare and forming networks between Senior community center and Senior welfare center, these centers set a goal of increasing quantitative and qualitative improving of leisure life of old people.

A neural network system was applied in order to analyze the nutritional and other factors influencing chronic diseases. Five different nutrition evaluation methods including SD Score, %RDA, NAR INQ and %RDA-SD Score were utilized to facilitate nutrient data for the system. Observing top three chronic disease prediction ratio, WHR using SD Score was the most frequently quoted factor revealing the highest predication rate as 62.0%. Other high prediction rates using other data processing methods are as follows. Prediction rate with %RDA, NAR, INQ and %RDA-SD Score were 58.5%(diabetes), 53.5%(hyperlipidemia), 51.6%(diabetes), and 58.0%(diabetes)respectively. Higher prediction rate was observed using either NAR or INQ for obesity as 51.7% and 50.9% compared to the previous result using SD Score. After reviewing appearance rate for all chronic disease and for various data processing method used, it was found that iron and vitamin C were the most frequently cited factors resulting in high prediction rate.

This paper introduces the public-oriented e-Hub construction for strategic alliances in the B2B virtual community. The public-oriented e-Hub can link with all participating Internet firms on the basis of their business models, and consequently help them share their core competence, management resources, and so on. Based upon this perspective, this paper presents the procedures corresponding with social network analysis for strategic alliances of small and medium internet firms. In addition, this paper tries to analyze the relationships among degree of competition, potential of strategic alliance, and financial performance. The results show that the firms with more easily accepting various strategic alliances make higher financial performance under more competitive environment. This suggests that strategic alliances through the public-oriented e-Hub in the B2B virtual community provide the internet firms with various opportunities.

Many classification studies for the community of densely-connected nodes are limited to the comprehensive analysis for detecting the communities in probabilistic networks with nodes and edge of the probabilistic distribution because of the difficulties of the probabilistic operation. This study aims to use convolution method for operating nodes and edge of probabilistic distribution. For the probabilistic hierarchy network with nodes and edges of the probabilistic distribution, the model of this study detects the communities of nodes to make the new probabilistic distribution with two distribution. The results of our model was verified through comparing with Monte-carlo Simulation and other community-detecting methods.

As the community antenna television (CATV) networks becomes ubiquitous, instead of constructing an entirely new broadband network infrastructure, it has emerged as one of the rapid and economic technologies to interconnecting heterogeneous network to provide broadband access to subscribers. How to support ubiquitous real-time multimedia applications, especially in a heavy traffic environment, becomes a critical issue in modern CATV networks. In this paper, we propose a time guaranteed and efficient upstream minislots allocation algorithm for supporting quality-of-service (QoS) traffic over data over cable service interface specification (DOCSIS) CATV networks to fulfill the needs of realtime interactive services, such as video telephony, video on demand (VOD), distance learning, and so on. The proposed adaptive fast expansion algorithm and the loading statistics with dynamic swapping algorithm have been shown to perform better than that of the multimedia cable network system (MCNS) DOCSIS.

The widespread adoption of the social computing paradigm has ushered in the development of online social innovation community (OSIC) as a promising method for solving social problems. Previous studies have not explicitly considered the conceptual factors that facilitate these communities' users' innovative activities, so it is vital to conduct empirical studies to verify the effectiveness of these factors. In this paper, the primary goals are to construct a theoretical model of the social innovation and empirically verify the casual relationship between theoretical factors and societal innovativeness. A survey of 398 OSIC users was conducted to empirically validate the theoretical model. The causal relationships between network characteristics and social innovativeness were experimentally tested. The results of this study indicated that ambiguity, switching, and multiplexity are important factors that facilitate social innovativeness, which contradicts the prior assumptions about innovation performance.

Wireless community networks (WCNs) are considered another form of ownership of internet protocol (IP) networks, where community members manage and own every piece of equipment in a decentralized way, and routing for traffic is done in a cooperative manner. However, the current routing protocols for WCNs suffer from stability and scalability issues. In this paper, an enhanced routing protocol is proposed based on the optimized link state routing (OLSR) protocol to meet the standards of efficiency in terms of stability and scalability. The proposed routing protocol is enhanced through two phases: multicasting expansion and multipoint relay (MPR) selection based on an analytical hierarchical process (AHP). The experimental results demonstrate that the proposed routing protocol outperforms the OLSR protocol in terms of network control overhead and packet delivery ratio by 18% and 1% respectively.

커뮤니티 네트워크는 이기종(heterogeneous) 노드들이 시간과 장소에 구애받지 않고 정보를 공유할 수 있는 통신 환경을 말한다. 이를 위해 이동 노드들은 사전에 구성된 통신 인프라 시설에 의존하지 않고 자가 구성될 수 있어야 하고 노드의 이동성으로 인해 변경되는 네트워크 토폴로지에 적응할 수 있어야 한다. 준-인프라 기반 무선 애드-혹 네트워크는 이러한 요구사항을 지원하기에 적합한 통신 기술이다. 본 논문에서는 준-인프라기반 애드-혹 네트워크 프로토콜의 실험에 용이한 평가 도구인 VTC(virtual topology coordinator) 시스템을 제안한다. VTC는 모든 통신장비간 단일 홉 통신만이 가능한 작은 공간에서도 선택적 MAC(Medium Access Control) 프레임 수신 메커니즘을 이용하여 다중 홉 네트워크 토폴로지를 가상으로 구성하도록 해준다. VTC 시스템은 실제의 무선 특성을 모두 반영하기는 어려우나 시뮬레이션을 통한 검증보다는 실 특성을 보다 다양하게 반영시킬 수 있다.
