Supporting communications among users, Social Network has encouraged various information flows through relationships among them. This paper studies on mentality or attitude of Social Network Services (SNS for short) users, on the basis of Technology Acceptance Model (TAM for short) and then proposes so-called TAMS, Technology Acceptance Model for Social Network Services. SNS users make full use of SNS as channels in order to create, expand, and obtain some information related to personal concerns. We will research on how the benefits that users get by using SNS exert influence on user-perceived usability. The SNS-using benefits focus on relationship benefits that are formed by interactions among users. Provided that perceived usability affects mental or informational benefits according to involvement of SNS users, we will check how perceived usability or ease of use is connected to brand attitude.

Why people reduce or stop using social network services(SNS), which are regarded as a mean of relationship and communication, unlike the early trend? To explain the phenomenon, this study tries to predict psychological decision making process of users from perspectives of cognitive dissonance theory. From this perspective, this study attempted an integrative approach that reflected 'User's literacy' indicating the ability of individuals to use SNS, and 'negative mass media influence' such as media reports on side effects or the bad experiences of acquaintances, along with the 3 factors used in the SNS Prior research. This study conducted an empirical analysis by surveying 256 facebook users, and the major findings are as follows:- First, Social-overload, complexity, uncertainty and negative media influence are significantly affect dissonance on the use of SNS. Second, Dissonance on the use of SNS significantly affects the behavior that possibly reduces and limits the use of SNS. In other words, the users who have experienced psychological dissonance respond passively by avoiding the use of SNS to resolve the dissonance. Third, the moderating effect of User's literacy wasn't a significant. This study presents a clue to understand psychological decision making process of use of SNS and a guideline for establishing practical strategies. In addition, it is important to note that this study contributes to expansion of theoretical discussion about usage.

The main purpose of the article was to explore the way education react and adapt to the emergence of social network and SNS. It tried to provide major theoretical grounds that bridge education and social network. In the due process, the researchers have examined the curriculum and instructional design process of education from the perspective of disruptive and sustainable aspect of SNS technology. Consequently, four major theoretical grounds were identified and reviewed: Gibson's theory of affordance, Vygotsky's social constructivism, Rha's human visual intelligence theory, and the network theory. By investigating these theories, the educational potentials of social network and SNS were emerged. The SNS was viewed as a new medium with abundant potentials of expanding the learning space, empowering the affective aspects of learning, and facilitating the formation of group intelligence.

소셜네트워크(Social Network)는 전세계 사용자간의 커뮤니케이션을 지원함으로써 이용자들간의 관계형성을 통해 다양한 정보의 흐름을 유도하고 있다. 이를 통해 사용자는 다양한 혜택을 누리고 있으며 이는 우리사회에 커다란 영향력을 미치고 있다. 본 연구의 목적은 소셜네트워크 서비스(SNS) 이용자의 SNS 이용 심리 및 태도를 Davis의 기술수용모델(TAM)에 근거하여 연구하고자 한다. SNS 이용자들은 개인의 관심분야와 관련하여 다양한 정보를 생산하고, 확산하고, 획득하는 채널로서 SNS를 활용하고 있으며 이러한 활동에 따른 SNS 이용혜택이 소비자의 지각된 유용성에 어떻게 영향을 미치는지에 중점을 두고 살펴보고자 한다. 본 연구의 SNS 이용자 혜택은 SNS의 다양한 혜택 중에서도 이용자들 간의 상호작용을 통해 형성되는 관계혜택에 초점을 두고 있으며 이러한 소비자의 관계혜택 중 소비자가 느끼는 심리적 혜택과 정보적 혜택은 SNS이용자의 관여도에 따라 지각된 유용성이 다르게 영향을 미칠 것이라는 가정 하에 이와 관련한 지각된 유용성과 지각된 용이성이 브랜드 태도에 어떻게 연결되는지를 살펴보고자 한다.

This study aims to investigate the usage patterns of users in Social Network Services (SNS) where is an upsurge. Specifically, the paper considers the reason why young people more and more prefer online (or mobile) SNS activities rather than offline face-to-face social relationship. Furthermore, the drivers which affect SNS usages are considered from users' personal characteristics and social influences. User's personal characteristics include their personalities (extraversion and introversion), narcissism, and life satisfaction. Social influences involve subjective norm, visibility, and image. Affected by personal and social factors in SNS, users intend to show positive self-presentation, which refers to a behavior to selectively expose his/her goodness to others. As one of the most influential drivers affecting SNS usage, the positive self-representation has an effect on the level of SNS usage. Thus, this paper suggests the hypothesized research model focusing on positive self-representation in the relationship among personal characteristics, social influence, and user's behavior in SNS. Empirical data analysis with 100 questionnaires suggests that all hypotheses were adopted except for the effect of visibility among social influence factors on positive self-representation.

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.

The first purpose of this paper is to identify factors having an effect on the user satisfaction of the SNS(Social Network Services) users and to examine causal relationships among those factors. The second is to examine how the causal relationships between the factors could be changed in the service types in SNS, which would be divided into web based SNS and mobile SNS. For achieving the purposes, we established the research model and hypotheses based on Information Success and Technology Acceptance Model. The characteristics of the SNS users consist of Individual Innovation and Social Influence while the characteristics of the SNS system consist of Information Quality and System Quality. The hypotheses were verified by analyzing data, which was collected from survey research on users of the SNS, with AMOS 18.0 statistical package. As a result, the first, we observed that more important the SNS users would consider the social relation, more useful they would recognize the function of SNS. The second, we observed that faster and easier the users could obtain hourly information in diversity, more useful they would recognize the function of SNS. The third, we observed that more innovative the mobile SNS users would become, more negative they would consider the usefulness of SNS. The fourth, we observed that more important the web based SNS users would consider the social relation, more negative they would consider the usefulness of SNS.
