Information sharing behavior in the Internet has raised much interest. Recently, social network sites provide a new information sharing channel for the users who want to connect with others based on common social background or tastes. Especially, we focus that a social network site becomes one of major routes for information sharing about socially influential issues. Therefore, studying how information is diffused via a social network site may give theoretically, practically significant implication. Based on the assertion, we investigated user's behavior to mediate other user's information messages. We define information mediating behavior as concurrent actions of filtering and distributing behavior of the digital content that is originated from one of the connected users. In this study, we intended to understand the effects of information mediating behavior, and tried to understand characteristics of re-mediating of previously mediated information. Using an agent-based simulation model, we found that information mediating behavior increased the extent of information diffusion significantly. In addition, even a small degree of mediating probability could boost up the level of information diffusion in the case of a re-mediating condition. We believe that those findings provide remarkable insight of research and business application on both of information sharing and diffusion in a social network site.

Due to the development of digital appliance, role of TV causes both-way by introducing IPTV, and SNS service causes big change of watching environment and residence environment. There are good conditions on the role of integrated control because it is arranged in the living room which secures movement most effectively and because family members can easily use, and the degree of use is high. Therefore, we infer user's needs by analyzing user scenario and current role of TV in home network environment. Primarily, we collect surveys of development scenario and technology which companies suggest TV applied by home network service, and secondly, we comparatively study scenario which the companies mentioned above suggest through observing user scenario, and study the role of IPTV in the future through actual scenario-based experiment by ethnography. After analyzing user scenario through case study and experiment, there are integrated device studies mainly in company study because it can be made up inside home, security and entertainment. On the other hand, there are patterns of user behavior by scenario experiment mainly in auto-tainment, security, and it showed that it is insufficient for interaction between TV and home media peripheral. Through this paper, we analyze context of home user, and based on this, we could suggest effective use of service development. Also after analyzing user form, we could know it also should be considered of ratio between activity inside home and activity outside home.

In the modern management literature, knowledge has been recognized as a new strategic resource enabling a firm to create its competitiveness. Shipping companies under fierce competitive structure need to pay attentions to the utility of knowledge management. A shipping firm may develop its unique service capability by classifying, sharing, and transferring the data, information and knowledge obtained from both inside and outside its global service network. The current study attempts to analyze influential relationships between liner shipping firms' knowledge management and service capabilities. In order to achieve this goal, this study designed a knowledge chain model measuring shipping companies' knowledge management levels and tested its validity and reliability based on a total of 80 replied questionnaires from national and foreign liners. The empirical result presents that supportive and primary activities composing a knowledge chain could exert significant positive influences on the enforcement of shipping service capabilities. This research shows that the utility of knowledge management is adoptable in the maritime industry, and recommends that shipping firms should recognize strategic importance of knowledge and actively pursue knowledge management at an entire firm level.

We construct product networks from the retail transaction dataset of an off-line department store. In the product networks, nodes are products, and an edge connecting two products represents the existence of co-purchases by a customer. We measure the quantities frequently used for characterizing network structures, such as the degree centrality, the closeness centrality, the betweenness centrality and the centralization. Using the quantities, gender, age, seasonal, and regional differences of the product networks were analyzed and network characteristics of each product category containing each product node were derived. Lastly, we analyze the correlations among the three centrality quantities and draw a marketing strategy for the cross-selling.

Researches recently made in advanced countries into entrepreneurship found that various resources and information are mainly provided to ventures through social capital, which is a resource capital based on a network, and through corporate entrepreneurship. This research is an exploratory study on the effects of social capital and corporate entrepreneurship of new ventures upon their corporate performance, conducted from the standpoint of dynamic capability. For that purpose, a questionnaire investigation was made of 171 venture entrepreneurs in Korea, and the following are the results of an empirical analysis of responses to the questionnaire. First, it was found that social capital, which is a resource capital based on a network, had a significant effect on corporate entrepreneurship. Second, social capital also had a significant effect on ventures corporate performance. Third, corporate entrepreneurship had a significant effect on corporate performance. These results imply that social capital and corporate entrepreneurship have a significant effect on the corporate performance of ventures, which have innate disadvantages concerning the supply of resources. On the other hand, ventures, which encounter relatively more intense demands for change and renovation, can be managed in a sustainable manner just when they adequately accumulate their social capital and utilize their external resources and appropriately conduct their corporate entrepreneurship activities.

Companies see a new business opportunity in the increased popularity of social network services and the related studies are also gaining more attention. This study attempted to analyze the social networks and thereby find a pattern in the use of social network services. Network users' pattern has been categorized by their purpose of use. Among various social network services, we selected the Facebook and its users were analyzed by a network analysis tool called NodeXL. In the end, several subgroups have been identified in a seemingly homogeneous network. Furthermore, the network shape differences according to the usage of social network services has been studied by comparing "friends" of an individual Facebook user with those of the K University Facebook page.

In Twitter, a user can post a message below 140 characters on his/her account, and can also repost a message of other users who the user follows. The message posted by the user in turn can be seen and reposted by other users who follow the user, which is called Re-tweet (RT). While some messages spread widely, other messages have relatively less or no RT. What factors cause these quantity variances of RT originated from original messages? How can the messages become influential in online social networks? As an effort to answer the above questions, we focused on information vividness, message characteristics, and originator characteristics. In perspective of managerial implication, we expect that the findings of this paper will provide corporations with helpful insight on the Word-of-Mouth (WOM) effect for efficient and effective advertisements and communications when they send a message of new products or services through Social Network Services. In perspective of academic implication, we identify the effect of contents of a message on WOM, which has been dealt with by few social network researches.

본 연구는 국내 창업초기투자생태계의 현황을 진단하고 향후 진화의 방향과제를 도출하는 것이 목적이다. 2013년 정부의 투자중심 창업지원 생태계 구축정책에 힘입어 국내 창업초기 투자생태계는 보다 세분화되고 활성화 되고 있다. 종전의 엔젤투자와 VC 투자자로 양분되었던 벤처투자시장에, 특히 창업초기단계 개인엔젤투자조합, 전문엔젤, TIPS, 엑셀러레이터와 창업초기 전용VC 펀드인 인큐베이팅펀드와 청년창업전용투자펀드등에서 최근 마이크로VC펀드에 이르기까지 다양한 창업초기 VC 펀드가 창출되며 다양한 그룹의 투자자들이 생성 진화중이다. 이렇게 창업초기 다양한 투자자그룹이 생성되고 성장하고 있는 이면에는 정부의 매칭투자와 투자연계 R&D 자금이 큰 역할을 하고 있어 투자자들에게는 창업기업에게 Valuation과 투자 위험 관리에 큰 도움을 주고, 창업기업에게는 과도한 지분의 희석 없이 투자자금이 가진 장점의 혜택을 극대화하고 있다. 그러나 본 연구의 국내창업초기 투자생태계 진단결과, 국내 창업투자생태계는 다양한 투자자그룹이 생성되고 성장하고 있지만 서로 다른 투자자 그룹 간 공동투자나 후속투자 연계 등의 협업적 활동 및 회수네트워크 연계 등 활동은 아직 미흡하다. 또한 투자분야 자체가 모바일 및 인터넷서비스 분야에 집중되고 있어, 상대적으로 긴 시간의 보육과 성장검증기간 및 규모 있는 투자를 필요로하는 제조분야는 비중이 약한 편이어서 투자 대상 사업 분야의 다변화 필요하다. 뿐만 아니라 국내 창업초기투자생태계는 창업의 글로벌 사업성과를 내기 위한 글로벌 투자자들과의 연계구조는 미흡한 상황이어 이를 촉진할 방안이 요구된다고 할 수 있다.
