  • Interests on collaborative research and academic relationship among researchers have been increased. Collaborative researchers can maximize productivity, time and cost savings, and reduce the risk of research. An empirical study on the research productivity of co-authors' network and review efficiency of the reviewer network was conducted based on co-author networks and reviewer networks in Korea Society of IT Service. This study aims to find the characteristics of the co-author and reviewer networks, and to analyze research productivity and review efficiency in order to draw some implications. The meaning of interactions among professional groups was analyzed. Research productivity index was calculated using 728 authors' papers submitted to the society. In order to verify the effects of indicators of social network analysis on research productivity and review efficiency, correlation and regression analyses were used. As a result, the indicators of network centrality did not affect the review efficiency, but affect the research productivity.

  • Business diversification is inevitable to survive under the current competitive business environments. The advent of new businesses makes corporate governance more complicated through corporate combinations. Recent introduction of new accounting standard, International Financial Reporting Standards(IFRS), accelerates the need for corporate governance analysis. This study analyses the complex corporate governance system and its relation to the business performance using social network analysis. Corporate inter-governance networks can be visualized easily in a social network diagram. 552 corporate governance data are empirically analysed in the Korean stock market. The changes in In-Degree between networks are positively related with the changes in corporate sales volume. We can find the same results using operating profits as corporate performance proxy. The results show that social network analysis technique can be applied to investments in the stock markets.

  • In this paper we used classification algorithms on social networking. We are proposing, a new classification algorithm called the improved Decision Tree (IDT). Our model provides better classification accuracy than the existing systems for classifying the social network data. Here we examined the performance of some familiar classification algorithms regarding their accuracy with our proposed algorithm. We used Support Vector Machines, Naïve Bayes, k-Nearest Neighbors, decision tree in our research and performed analyses on social media dataset. Matlab is used for performing experiments. The result shows that the proposed algorithm achieves the best results with an accuracy of 84.66%.

  • 본 연구는 소셜네트워크의 구조적 특성인 연결밀도와 중심성에 따라 소셜쇼핑에 대한 구매의도의 차이를 검증하고자 실시하였다. 이와 함께 집단중심의 온라인 커뮤니티와 개인중심의 SNS(소셜네트워크서비스)간의 소셜쇼핑 구매의도의 차이를 제안하고 분석하였으며, 그 이유를 구체적으로 살펴보기 위해 구조적 특성을 반영한 가설을 설정하고 분석하였다. 분석결과, 연결밀도가 높은 경우에 소셜쇼핑에 대한 구매의도가 높게 나타났으며 중심성 역시 높을 때 구매의도가 높은 것으로 나타났다. 또한 온라인 커뮤니티와 SNS간에도 소셜쇼핑에 대한 구매의도가 차이를 보였는데, 온라인 커뮤니티에서는 연결밀도가 높은 경우에, SNS는 중심성이 높은 경우에 각각 구매의도에 중요한 영향을 미치고 있음을 발견하였다. 이러한 결과를 토대로 소셜네트워크 및 소셜쇼핑 연구에 있어 네트워크 구조의 중요성에 대한 시사점을 제시하고 소셜쇼핑의 구매의도를 높이기 위해 소셜네트워크 유형별 구조를 이해한 전략 수립의 중요성과 방향에 대한 시사점을 제안하였다.

  • 소셜네트워크는 다양한 콘텐츠와의 결합을 통하여 네트워크를 통해 형성된 지인 관계를 기반으로 공유와 배포를 원활하게 하는 주요 플랫폼으로 활용되는 등 몇 가지의 공통적인 기능을 가지고 있다. 이에 트위터, 페이스북, 카카오스토리를 모두 사용하고 있는 사용자들을 대상으로 설문조사를 진행하였으며, 설문에 응답한 자료를 통계 내어 각각의 서비스가 영향을 주는 요인들은 어떤 것인지 완성적 사회자본과 도구적 사회자본으로 나누어 분석한 결과를 제시하였다. 이 연구는 사용자들의 목적에 따라 소셜네트워크를 선택하는 기준이 되고, 새로운 소셜네트워크를 개발하거나 기존의 서비스를 발전시키는데 기여할 수 있을 것이다.

  • The study is to investigate which features are perceived by Social Network Service(SNS) users as the most required one to further boost the usage of service, and to examine the perception of these features of SNS sites varies according to their demographic and service usage characteristics. The study also is to suggest a few of research propositions on the relationships between required features of SNS sites and characteristics of SNS users, based on statistical analyses. To accomplish these research purposes, the study defined characteristics of SNS users including demographic(gender, age) and service usage one(start time of service usage, service usage place), and required features of SNS sites(system, service, information, emotion) based on the literature review of SNS. The results show, based on the statistical analyses using survey questionnaire on Korean and Chinese SNS users, that there are differences in perception of required features of SNS sites among the respondents grouped by age, start time of service usage, service usage place. Finally, the study proposed three research propositions, based on the analysis result, that could be used in SNS related researches in the future.

  • This research paper is focused on a theoretical study of the influences the structural factors and social capital within an industrial cluster have on innovative performance, and expanding the understanding of the influence through positive analyses based on public surveys. The study adopts a concept of social capital that can formulate a social relationship, and maintains that the social capital either works as a mediator for structural factors or independently exerts strong influences on innovative performance. In the research, the social capital is divided into two categories, bonding social capital and bridging social capital, and their influences are analyzed separately. The result of the analyses shows that unlike the traditional perception based on Korea's unique culture, the influence of bridging social capital is stronger than that of bonding social capital. It is also found that the structural factors exert influence by themselves on the contrary the previous study, simultaneously they still have influence upon innovative performance through bridging social capital calculated via the elements such as secondary relationships, network activity support and organizational openness.

  • This study examines how different uses of social network sites (SNS) and mobile phones (MP) to communicate with friends and business associates are related to the acquisition of job-related information, job mobility, and entrepreneurial intentions, using social capital as its main theoretical lens. To this end, a nationally representative, random digit dialing (RDD) survey was conducted in Singapore. Path analyses show that SNS interactions with friends are positively related to both bonding and bridging social capital. The former is linked with greater job mobility, the latter with entrepreneurship, and both are associated with more job-related information. SNS interactions with business contacts are directly positively related to job-related information and entrepreneurship. For mobile phones, interactions with friends are positively related to social capital, job information and entrepreneurship. Professional networking is associated with more bridging social capital, job information and job mobility. Bonding capital is found to be linked with greater job mobility, while bridging capital has a positive relationship with both entrepreneurship and job mobility.
