The wide spread of smartphones and the growth of the number of internet users are reshaping the SNS (Social Network Service). Merging into other service areas and creating new business models with high profits, SNS is no more a service simply providing personal connections. Now SNS has positioned itself as a service platform. SNG (Social Network Game) is a new outcome utilizing SNS as a game platform and showing a rapid growth rate in a short period of time. The number of SNG users is expected to increase steadily. In this study, we examine whether SNG user motivations lead to flow experience and future intention to use. For that purpose, we conducted a survey with smartphone users. The results indicate that flow experience functions as a mediator and user motivations indirectly affect intention to use through flow experience. This paper concludes with discussions on findings and suggestions for future research.

본 연구에서는 SNS 품질요인에 대한 기존 연구에 대해 전문가 집단이 산출한 각 품질요인에 대한 중요도와 사용자 집단이 각 품질요인에 대해 중요하다고 생각하는 중요도의 차이를 알아보고자 하였다. 연구를 위하여 선행연구에서 사용된 SNS 품질요인을 시스템품질, 정보품질, 인터페이스품질, 서비스품질로 구분하여 AHP 기법을 적용하여 전문가 집단과 사용자 집단의 품질요인별 중요도를 실증 분석하였다. 분석결과 전문가 집단과 사용자 집단의 각 품질요인에 대한 중요도의 인식 차이가 나타나는 것으로 나타나 품질평가에 있어 전문가와 사용자의 의견을 종합하는 종합 평가가 필요할 것으로 사료된다.

In recently, the SNS which is the hot issue of the knowledge-based information age use various goal based on human networking. This service construct a human relationship which exchange of information and opinion freely, and can extend the human network relationship using open his profile and closeness others. But, each individual's privacy invasions and pissing based on information open and sharing are rising. In this paper we present a method of protecting the SNS group's communications and information interchangeability efficiently.

최근 분산 시스템의 기술이 발전하면서 소셜 네트워크 서비스(SNS)도 분산방식으로 전환해가는 추세이다. 특히, 모바일 기기 발전과 공급 확산으로 인해 모바일 기기의 분산 SNS에 대한 연구로 클라우드 컴퓨팅 기술을 응용한 모바일 클라우드 SNS가 연구되고 있다. 또한, 제 3자의 미인증 모바일 기기를 사용한 SNS 접속으로 인한 피해가 증가되고 있는 반면, 이를 방지하는 사용자 모바일 기기 인증에 대한 연구는 미흡하다. 따라서 본 논문은 Proxy Re-Encryption 기술을 응용하여 안전한 모바일 기기 인증 프로토콜을 제안한다.

SNS(Social Network Service)를 사용하는 인구가 급증함으로 인해 개인의 생각이나 많은 자료들을 SNS 공간을 통해 공유함으로써 많은 문제들도 같이 발생하고 있는 추세이다. 대부분의 SNS는 자신의 공간에 게재된 정보에 대한 접근권한 만을 설정할 수 있고 자신이 타인의 공간에 게재한 게시물에 대해서는 접근 권한 설정에 대한 자격을 부여하지 않는다. 이를 통해 원치 않은 사용자들에게까지 자신의 개인 정보가 노출되는데, 이는 SNS 안에서의 문제만이 아니라 2차적인 문제도 만들어 낼 수 있다. 따라서 본 논문에서는 SNS 환경에서의 프라이버시 보호를 위한 태그 정보 접근 방법을 제안한다. 본 제안사항은 사용자의 태그정보에 대한 접근권한 설정을 통해 원치 않는 사용자가 2차적인 문제를 발생하지 않도록 제어할 수 있다.

This study deals with the policy proposals focusing on the addiction for the rapidly growing social media service (SNS) and its diagnosis. Researcher intends to define the SNS addiction and develops a diagnostic measure, which is a valuable subject. The reason is why the SNS becomes more convenient with prevalence of smart phones and the SNS addiction becomes enough severe to suggest internet addiction policy. Researcher presents the subjects into three parts. Firstly, the SNS addiction variables are derived and validated. Secondly, the path model between the SNS addiction variables is verified and discussed. Thirdly, researcher proposes the diagnostic results and the group comparison. Therefore, the result of this study is that the SNS addiction can be measured by the four elements, which are the failure in stopping the use of the SNS, time tolerance, living disability, withdrawal and anxiety. Researcher verifies the sequential impact of each variable and figures out the SNS addict through the presentation of a realistic measurement for the addiction index and the determination of the level of the addiction. By the above result, the researcher proposes the public relations of the government policy for the sound usage of the SNS and the self management of user. Finally, various proposed in this study will help to prevent juvenile crime, social problems in the future.

Fear of missing out (FoMO) refers to the desire to stay continually connected with what others are doing because they are afraid of missing the flow or not being included. Although FoMO has been recently proposed as a widespread phenomenon within social media, there has been few empirical research by which mechanism FoMO leads to social networking service (SNS) addiction. Therefore, this study examined whether FoMO mediated the relationship between adolescents' attachment and SNS addiction proneness. A total of 517 middle and high school students participated in the study and completed self-report questionnaires. Results showed that FoMO partially mediated the relationship between adolescents' parental attachment and SNS addiction proneness, whereas the relationship between adolescents' peer attachment and SNS addiction proneness was fully mediated by FoMO. These results suggest that unstable attachment might contribute to SNS addiction through FoMO, especially in case of peer attachment. Lastly, we discussed theoretical and practical implications of this study and suggestions for future research.

The purpose of this study is to compose direction about mUC as a communication channel in the company. Recently, many companies have started to adopt or try to vitalize the use of mUC. This study starts from the viewpoint of communication which is the original purpose of SNS or mUC. The purpose and function of life-world are drawn based on Habermas' theory of communicative action. Firstly, this study will check on a difference in usage over the action and articulation between SNS and mUC. Secondly, this study will examine a difference of effect of life-world between SNS and mUC. Thirdly, to check that there is difference according to the user characteristics. The result is that there are differences about action and articulation but little differences of effect to the life-world between SNS and mUC. Also, there is difference according to the user characteristics. This study could contribute to compose direction when a company adopts or vitalizes mUC.

Given the rapid growth of social network services (SNS) such as Facebook and Cyworld, it is important to understand SNS users' decision-making processes such as purchasing and continuance intention. Especially, as a number of SNS providers such as Cyworld and Habbo Hotel recognize the sales of digital items as the main source of their profits, it is critical to in-depth understand SNS users' purchasing behaviors. In this regard, this study explores continued usage behaviors and purchase behaviors of digital items in an SNS environment using a longitudinal research method. This paper develops a theoretical model to deeply understand the key drivers of purchase behavior of digital items through constructs prescribed by two established research streams on information systems, namely continuance usage and habitual usage. Moreover, this study examines the effects of actual and ideal self-image congruity on SNS continuance intention and habit. The research model was tested by using survey data collected from 307 users who have experience with Cyworld. The analysis results show that SNS actual usage directly influence purchase behavior of digital items. SNS users' continuance intention and habit are key drivers to enhance the level of actual usage of the SNS. Both actual and ideal self-image congruity play a key role in enhancing continuance usage and habitual usage. The implication of research and discussions provides reference for SNS providers in marketing and IT strategy.
