This paper proposes a public oriented e-Marketplace that induces strategic coalition using database in which detail information about each firm is contained. A public oriented e-Marketplace links each firm through the type of Internet business model and constructs a trading community. We introduce a design methodology of public oriented e-Marketplace called as social network analysis. Social network analysis helps each firm's network easily visualized and completely modeled. Additionally, this paper tries to analyze the relationship among the level of competition, potential of strategic coalition, and financial performance. We demonstrate the firm to easily accept various strategic coalitions can make higher financial performance under the more competitive condition. This implies that strategic coalition through public oriented e-Marketplace provide the each firm with various opportunities.

While general belief is that the military alliances are stable and rigid, the authors argue that the states are far more flexible in their behavior and often act against their alliances. This paper looks at states' behavior in the UN GA and looks how it is reflected in participation in military alliances during three periods of history since 1976 to this day. The authors illustrate the need to consider the network representation of co-sponsoring groups in General Assembly votes. They find significant support for their argument, indicating that social aspects can be extended beyond alliances. An application of social network analysis shows some unexpected affiliations in UN GA. If the UN GA is the "true" nature of these countries' alliance strategies, then it might suggest some significant defections and interesting association.

To upgrade home style recommendations and user satisfaction, this paper proposes a personalized and optimized recommendation algorithm for interior design style based on local social network, which includes data acquisition by three-dimensional (3D) model, home-style feature definition, and style association mining. Through the analysis of user behaviors, the user interest model is established accordingly. Combined with the location-based social network of association rule mining algorithm, the association analysis of the 3D model dataset of interior design style is carried out, so as to get relevant home-style recommendations. The experimental results show that the proposed algorithm can complete effective analysis of 3D interior home style with the recommendation accuracy of 82% and the recommendation time of 1.1 minutes, which indicates excellent application effect.

The WeChat mini program is an application embedded in WeChat that users can use without downloading and installing. After it was officially released in 2017, many travel enterprises have launched their own mini programs on the WeChat platform. This study applies affordance theory to investigate the WeChat mini program's role in tourism activities through social network analysis using the R programming language. The authors searched the topic of "how do you perceive the travel-related WeChat mini program" and then crawled the 200 comments found; 180 comments were analyzed after data cleansing. The results show that travel-related WeChat mini programs play a very important role in Chinese social network tourism activities. This paper found that WeChat played a more active role in various tourism-related interactions with Chinese social networks. Moreover, the results show how affordance theory is applied to the use of WeChat mini programs.

This research investigates the characteristics of the mobile social commerce and explores the moderating effects of perceived risk and price sensitivity. This survey targeted consumers in their 20s to 30s who use mobile social commerce applications. We used 261 questionnaires for the final statistical analysis. Descriptive analysis, factor analysis, reliability analysis, and hierarchical regression analysis were applied in the data analysis. The results are summarized as follows. First, characteristics of mobile social commerce are composed of economics, informativeness, entertainment and promotion. Second, perceived risk (which had a negative effect on purchase intention) had moderating effects between perceived risk and economics or entertainment. Third, price sensitivity (which had a positive effect on purchase intention) had a moderating effect between price sensitivity and promotion. This study contributes to the disclosure of the role of perceived risk and price sensitivity as moderating factors between the characteristics of mobile social commerce and purchase intention. Finally, useful implications (both academic and practical) are provided for fashion retail managers.

전 세계적으로 하루 평균 6,000만 통의 이메일이 전송되고 있다. IT 기술의 발전 덕분에 우리는 다양한 방법으로 커뮤니케이션을 할 수 있게 되었고 트위터와 같은 기술은 단순히 우리가 다른 사람들에게 나의 자잘한 일상을 이야기 하는 기회를 주는 것에 그치지 않고 더 큰 일을 하게 하는 강한 잠재력을 지니고 있다. 트위터로 어떤 일을 할 수 있는지 알고 이해한다면 우리의 삶을 타인들과 좀 더 의미 있는 방식으로 교류하고 공유하게 될 것이다. 본 논문에서는 Web과 Social Networks 최근 동향과 디지털 뉴미디어 시대의 미니 블로그와 Twitter 서비스에 대해 살펴본 후, 소셜 미디어 활용전략과 Twiter의 향후 발전방향을 제안하였다.
