Social Network Service(SNS) is a kind of advanced Internet service that acts as personal media. This study was intended to find out the structural relationships among factors affecting the usage of social network services by extending the Technology Acceptance Model(TAM). For this purpose, the variable 'Flow' was first integrated into the TAM in order to understand the internal motivations of users. And then the external factors of SNS usage were derived from the perspective of users, contents, and media side of SNS, and finally the dependent variable was set with the intention of sustainable use. Then these factors were carefully integrated into a structural model. We expect the findings of this study will be very helpful for the internet marketing professionals, SNS developers, and the others.

In this paper, we propose a method to reduce mobile social network services (SNSs) traffic using a mobile integrated SNS gateway (MISG) to improve network communication performance between the mobile client and SNS servers. The gateway connects the client and SNS servers using the contents adapter and the web service adapter and helps to improve communication performance using its cache engine. An integrated SNS application, the user's client, communicates with the gateway server using integrated SNS protocol. In addition, the gateway can alert the client to new SNS contents because of the broker server implemented by the message queuing telemetry transport protocol. We design and develop the modules of the gateway server and the integrated SNS application. We then measure the performance of MISG in terms of content response time and describe the result of the experiment.

Social network service(SNS), provided by social network sites such as Facebook, Twitter and Cyworld is rapidly growing in online business. Furthermore, many companies have growing interests in finding effective ways to use SNSs for their innovations, marketing and advertisement. In fact, firms have recognized the utility value of the SNS for their business. In this aspect, this study attempts to identify key factors influencing the intention to continuous use of SNSs. Based on the UTAUT(the Unified Theory of Acceptance and Usage of Technology)model, this study proposes the research model, including the effects of social network service characteristics(social relationship support, information sharing, image expression) and individual characteristics(self-disclosure, extroversion, familiarity) on performance expectancy as well as the moderating effect of perceived information security among UTAUT variables. The 412T sets of data collected in a survey were tested against the modeling using SEM using SmartPLS. Results indicated that social network service and individual characteristics had significant effect on performance expectancy with exception of self-disclosure. In addition, the moderating effect of perceived information security had significant effect.

In sum, we assume that the users may communicate well each other and pay attention to build closely a social network using that kind of activities. However, nevertheless the new trends of communications and sharing knowledge become popular, researchers have just began the research issues in explaining why Internet user rush into SNS and enjoy the time in there.

소셜 네트워크를 통해 생산 유통되는 정보들은 신뢰할 수 없는 불분명한 정보들이 많고 그런 정보들이 무분별하게 확산되기 때문에 사용자들은 정보에 대한 신뢰성 여부를 판단하기가 힘들다. 특히 정보의 신뢰성에 대한 평가가 전적으로 사용자들의 판단에 맡겨지고 있는 상황에서, 온라인 정보의 신뢰도에 대한 체계적인 평가 방안의 마련이 절실하다. 본 논문에서는 소셜네트워크서비스의 신뢰도 평가 지표로서 KTI (Korean Trust Index for SNS)를 설계하여, 서비스 사용자들이 정보의 신뢰성을 판단할 수 있는 기준을 제시하였으며, 이를 통해 사회적 신뢰 수준을 분석할 수 있도록 하였다. SNS의 서비스 특성을 고려하여, 신뢰도에 영향을 주는 요인을 정의하였고 이를 바탕으로 온라인에서 유통되는 정보에 대한 신뢰도를 평가할 수 있는 신뢰모델을 설계하고 신뢰지수 KTI를 제시하였다. 신뢰지수 KTI의 개발은 SNS에 대한 신뢰 수준을 측정하여 이를 정량화함으로써, SNS 연결망을 효율적으로 활용하기 위한 신뢰 확보가 가능할 것으로 기대한다.

This study establishes a simple Causal Map in order to understand the structure of Social Network Services(SNS). From this, the paper proposes a simulation with drawing Simulation Model and it examines whether a Dunbar Number is available for the emergence of collective intelligence based on an on-line network. Through my analytical research, it turn out both Closed SNS and Open SNS have their own Dunbar Number. However, it appear that Open SNS can expand infinitely as it has a unique property namely weak tie. This implies that it is significant for a system or policy to be developed in order to overcome the problem of Dunbar Number, whereas restricting the extension of a network by considering the Dunbar Number would have a negative impact on emergence of collective intelligence.
