In this paper, using trade data of 57 HS 4 digit based agricultural and food(agro-food) products among 47 countries during 2005 to 2014, the international competitiveness and trade structure have been analyzed from the context of global networks employing the methods of social network analysis. Firstly, the differences in the network structure by agricultural products have been revealed. The number of disconnected groups was significantly lager in order of vegetables, fruits and processed foods. Secondly, the differences in the community structure by agricultural and food products have been also revealed. That is to say, for some commodities, the community structure has been changed dynamically, on the other hand, there are some agricultural products that have not changed its community structure despite the increasing trends of trade volume. Thirdly, even though the international competitiveness of Korea's agricultural products was still very limited in the sense that only 26 items have been included in the top3 network of 57 agricultural products, there has been possibilities of the increasing patterns of the competitiveness.

This study aims to illustrate the essence of meaning through sexual minorities' participant experiences in a sexual minority community. This research intends to explore essential meaning structure revealed in sexual minorities' reasons for joining a sexual minority community and in their experience in community activities. The study participants were 8 sexual minorities, and data was collected by in-depth interview. Data analysis was described using Giorgi's analysis methodology in phenomenological research method. As a result, the sexual minorities' participation was consisted of 13 meaning units, 6 derived topics, and 3 essential topics, which were 'An unquenchable thirst', 'Another world called oasis', and 'Real estrangement' Moreover, based on the essential topics, the study participants' common meaning of essence was analyzed as 'spiritual diaspora'. Sexual minority communities shall contribute to developments of own organizations through mutual compensations by vitalizing exchanges with other communities based on this study. Also, the communities should the variety in sexual minorities to allow various people's participation. People's awareness on sexual minorities must be transformed so that closed communities can change. Comprehensive knowledge on sexual minorities should be distributed in the social welfare fields so that sexual minorities may search solutions on issues through various access not limited to certain communities.

This study conducts to examine the effect of purchase intention on social shopping by connection density and centrality which is a structural characteristic of social network. Furthermore, this study suggests and analyses the difference of social shopping purchase intention between online community which focuses on a group and SNS(social network service) which focuses on an individual. To examine these reason, this study proposes hypotheses that reflects structural characteristic then analyses them. The result of analysis shows that the purchase intention on social shopping seems to be high when the density of connection is high and the purchase intention seems to be high when the centrality is high as well. Moreover, there is difference in the purchase intention on social shopping between online community and SNS and it is found that both cases where the connection density is high in the online community and the connection centrality is high in SNS have significant impact on the purchase intention. Based on these results, this study provides an implication on the importance on network structure in social network and social shopping and to increase the purchase intention of social shopping, this study suggests the implication on the importance and direction which understands the structure of social network type.

Web 2.0 paradigm and technologies allow users to contribute their information voluntarily and actively to online community. This paper aims to investigate key determinants of information contribution in online communities. We come up with the research model and proposed hypotheses on the basis of intensive literature review on motivation theory, information literacy, and self expression. Using survey response date collected from those who have ever experienced in uploading or providing information on online community such as social media. A total of 262 survey responses were used to test research hypotheses. The results show that self expression motive influences on information representation capability(IRC) and information contribution. The impact of Information literacy on IRC is found to be significant, and IRC is positively related to information contribution. In addition, approval motive is proven to be key determinant of IRC and information contribution. Some practical implications of these findings are discussed.

현재 우리나라의 오픈마켓은 저가 구조로 수익과 성장에 한계를 맞고 있지만 이미 외국에서는 소셜 네트워크를 중심으로 소셜 쇼핑이 소비자 주도의 쇼핑몰로 인기를 얻고 있으며 새로운 쇼핑몰 형태로 각광받고 있다. 소셜쇼핑은 블로그나 커뮤니티와 같은 사회적 네트워킹 서비스를 기반으로 어떤 특정 인터넷 쇼핑몰에 구애됨 없이 다양한 상품을 각 개인이 퍼 오거나 게시하고 이에 대한 상품평과 사용후기를 개인 블로그나 커뮤니티에 올리거나 올리게 하여 거래가 일어나도록 하는 전자상거래 방식이다. 소셜 쇼핑은 사람/정보/쇼핑 검색이 가능하고 블로그나 커뮤니티를 통한 정보 공유가 가능하며 타 판매 사이트로부터 쇼핑 구매도 가능하다. 소셜 쇼핑은 또 하나의 플랫폼을 제공하며 다양한 판매자, 소비자, 광고주 등과 제휴가 가능하고 네트워킹이 가능하기 때문에 변화하는 소비자들의 특성을 반영하고 수익의 한계를 돌파하기 위한 진정한 web 2.0 쇼핑형태로써 발전 가능성이 크다.

현재 전 세계 각국은 지식 경쟁력 확보에 혈안이 되어 있으며, 우리나라는 풍부한 인터넷 인프라를 구비하여 지식 강국으로 발돋움하기 위한 충분한 토대를 마련하고 있다. 특히, 인력은 인터넷 시대의 핵심적 지식 자원으로서, 전문가 두뇌 연계 망(네트워크)의 구축과 운영을 통해 해당 분야 전문가간 협력 및 교류가 진행되면, 지식 정보의 동시 생성, 공유, 활용 체제의 확립이 가능하다 전문가 커뮤니티의 구성원은 정보의 공유와 확산에 자발적으로 기여하는 지식의 선 순환 구조를 이루게 될 것이다. 본 논문에서는 국내외 과학기술 전문가로 구성된 한민족과학기술자 네트워크(KOSEN, www.kosen21.org)를 사례로 전문가 네트워크의 역할과 특징을 살펴보고, 지식 기반 사회에서 전문가 네트워크의 발전 방향을 제안하고자 한다. KOSEN은 지식의 생성, 공유, 활용 등의 지식관리 프로세스를 지원하는 과학기술 전문가 커뮤니티이다. 향후 인적 자원 및 정보 자원의 적절한 연계를 통해 지식의 활용 측면을 더욱 확대하여 본격적인 지식 정보 활용의 장으로 거듭나야 한다. 컨텐트 가치증대를 통한 전문가 참여 확대, 전문가들간 상호 연계의 확대를 통한 소 공동체 형성, 전문가들간 상호 학습, 정보 거래 메커니즘 구축 등의 다양한 방안을 통해 보완될 것으로 기대한다.

컴퓨팅 환경이 점점 분산되고 협업의 필요성이 점점 증대되고 시스템간에 상호작용(interaction)이 동적이고 복잡해지면서 기존의 협업 시스템 패러다임을 벗어난 커뮤니티 컴퓨팅을 구성하는 요소를 정의하고 커뮤니티 모델의 에이전트들의 상호작용 유형을 프로토콜의 형식으로 모델링 하는 방법과 지정된 프로토콜들을 실행하기 위한 방법으로소 에이전트 플랜(plan)을 이용하는 방안을 제안한다. 커뮤니티를 구성하는 요소들은 역할(role), 정책(policy), 구성원(member), 프로토콜(protocol)등이며 각각의 요소는 BDI 구조를 가지는 에이전트와 플랜, 목적(goal), 사실(fact)등의 결합으로 표현이 가능하다. 에이전트들은 프로토콜에 나타나는 유형을 서술한 플랜을 통해서 상호작용을 하게 된다. 본 논문에서는 이러한 프로토콜을 실행 가능한 플랜으로 변환하기 위한 4가지 유형을 파악하여 각각의 유형을 플랜으로 변환하는 방법을 제안한다. 제안된 방법은 시뮬레이션을 통하여 완전성과 유효성을 보인다.

In this paper, we study changes in company revenue structure. For this, we introduce a new concept for an expanded e-business community - Supra Hub. Based on this concept, we analyze current problems with regard to revenue structure in industry-specific cases and propose advisable alternatives. These alternatives are derived from Burts research on Network and Organization. We conclude that new community is coming connecting industry-specific networks.

Modern society is complex and rapidly changing, and knowledge sharing is needed to acquire and create knowledge. Knowledge sharing is the act of providing information knowledge and know-how of their own in order to cooperate with or help their colleagues. This study presents a research model using social capital theory to explain the mobile knowledge sharing behavior of virtual community members. Based on previous studies, social capital theory is divided into structural, relational, and cognitive aspects. It was composed of social interaction ties as a measure of structural aspect, trust as a measure of cognitive aspect, shared language, shared vision and relational aspect. After collecting survey data, factor analysis and regression analysis were performed using SPSS 22. In this way, we examined how the detailed factors of social capital affect information sharing behavior and how the level of knowledge sharing affects community promotion. The results showed that social interaction ties, shared language, shared vision, and trust affect knowledge sharing. Knowledge sharing has had a positive impact on community promotion.
