Purpose - This study aims to empirically verify the impact of media richness, social presence, and prior life satisfaction on various continual usage or withdrawal behaviors of SNS users via both a positive path of satisfaction and a negative path of relative deprivation. By identifying these causal paths, we observe dynamic interactions of SNS user psychology in a balanced view, and provide some implications about design principles for SNS providers. Research design, data, and methodology - We developed 16 hypothesis based on media richness theory, social presence theory, social comparison theory, the literature about relative deprivation, and the literature about the various reactions of IS users. The rich SNS media, social presence recognition among peer SNS users, and prior life satisfaction could generate positive experience, attitude, and virtuous behavioral intentions among SNS users. At the same time, rich media, low social presence, and low prior life satisfaction could generate relative deprivation and could increase withdrawal behavioral intentions such as refusal to provide information, misrepresentation of information, and removal of uploaded information in SNS. Scenario surveys were conducted to collect data from potential SNS users. Data from 357 surveys were collected and analyzed through a PLS algorithm to test the hypotheses. Results - Media richness, social presence, and prior life satisfaction could significantly increase perceived enjoyment, satisfaction, and behavioral intention of continual usage and knowledge sharing. They also could significantly decrease refusal and misrepresentation intention. Relative deprivation is significantly decreased only by prior life satisfaction. Relative deprivation could not significantly decrease satisfaction, but it could significantly increase misrepresentation and removal intention, which could be regarded as information distortion intention. Conclusions - SNS providers should focus on developing rich media and social presence support because these two variables could impact the positive experiences of SNS users. Moreover, the positive experiences could heavily influence SNS user behavior. Some management is needed to prevent relative deprivation and its consequences of misrepresentation and removal intention. SNS providers should prevent SNS users from excessive image misrepresentation and removal as this information distortion could be the source of relative deprivation.

Social networking services (SNS) is an indispensable method in order to obtain information of the Internet participants. The study identified three variables of social media communication, sharing culture, and online trust in terms of social capital theory (SCT) and reviewed intention& behavior variables in terms of theory of planned behavior (TPB). The data were collected from 330 samples of SNS user, and were involved, and the research model uses AMOS to make confirmatory factor analysis. The findings confirmed our hypothesis that social media communication, sharing culture, and online trust affect individuals' behaviors to sharing information. This study emphasizes that not only social media communication but also sharing culture to SNS can stimulate information sharing. while previous research has predominately focused on personal cognition or social network, the study examines the integrated influence of communication, culture and trust on information sharing in SNS. In sum, by explicating the unique role of social capital, this paper aims at contributing to the continued development and success of SNS in general.

With the rapid growth of the internet, Social Network Services (SNSs) have played an important role. As the use of SNSs increases, users experience a sense of responsibility to respond to other people's messages or requests, and consequently experience an social overload, feeling too much social support for other users. In this study, we examined the effects of social overload on loneliness and SNS discontinuous usage intention. To verify the research model, data were collected from 83 SNS users and analyzed using SmartPLS, a structural equation modeling tool. The results of this study showed that the communal orientation and the degree of use of SNS influenced the social overload, and the social overload had a significant effect on loneliness and SNS discontinuous usage intention. The findings of this study are expected to help understand the social overload and loneliness in the use of SNS, and may also provide a strategic direction for SNS service providers.

With the rapid development of digital media, there has been a huge change in a way of communication, a process of information diffusion and a role of traditional media. Not like mass media, social media enables users to generate and tap into the opinions of a larger world. From that reason, social media is impacting marketing strategies. However, still social media marketing researches just focus on case study, analysis of users motivation or analysis of power user's usage pattern. Word-of-mouth has always been important especially in marketing area. In social media, word-of-mouth depends on each user that's why this research focuses on individual user's activity in SNS. I defined 4 factors (produce, diffusion, network size, activity of network size enlarge) that are effect on activity and verified hypothesis by multiple regression analysis, hierarchical regression analysis and moderated multiple regression.

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.

소셜 러닝은 미래 지식정보사회의 새로운 학습모델로 기존의 학습과 달리 개인의 능동성과 타인과의 관계 형성을 강조한 것으로, 블로그, SNS, 위키, UCC, 마이크로블로그 등과 같은 소셜 미디어를 학습플랫폼으로 활용하여 소셜의 효과가 학습으로 연결될 수 있도록 설계할 수 있다. 본 논문에서는 소셜 러닝을 이해하기 위한 세가지 키워드인 맥락, 연결, 협업을 중심으로 소셜 러닝 특성을 기술한다. 각 소셜 미디어 특징을 조사하여 소셜미디어가 소셜 러닝에 어떻게 활용이 될지를 알아보고 페이스북을 활용한 소셜러닝 시스템 구축 방법을 제시한다.

본 연구는 남녀 청소년을 대상으로 SNS중독상태, 현실공간 및 가상공간의 자아정체감의 상태를 확인하고, SNS중독여부와 현실공간 및 가상공간에서의 자아정체감 사이의 관계를 규명하고자 시행되었다. 연구대상자 중 남성이 여성보다 SNS사용 시간이 더 많았고, SNS친구 수가 많을수록 SNS 사용을 더 많이 하는 것으로 나타났다. 현실과 가상공간에서의 자아정체감 하위 영역 상관관계에서는 대부분의 영역에서 정의 상관관계를 보였으며, 현실공간 자아정체감과 SNS중독의 각 하위 영역과도 모든 영역에서 정의 상관관계를 보였다. 그러나 SNS중독과 가상공간 자아정체감의 영역에서는 주도성을 제외한 나머지 영역에서 음의 상관관계를 나타내었다. 이를 통하여 SNS중독 대상자들에 대한 교육과 관리가 필요하며, 현실공간 및 자아정체감의 각 하위영역별로 대상자들을 중재할 수 있는 프로그램이 개발되어야 할 것이다.

소셜 미디어 (Social Media)는 사람들이 자신의 생각과 의견, 경험, 관점 등을 서로 공유하고 참여하기 위해 사용하는 개방화된 온라인 툴과 미디어 플랫폼으로서 소비와 생산의 일반적인 흐름이 동작하지 않으며, 양방향성을 활용하여 사람들이 참여하고 정보를 공유하며 사용자들이 만들어 나간다. 이런 소셜 미디어에는 블로그(Blog), 소셜 네트워킹서비스(Social Networking Service, SNS), 위키(Wiki), 손수제작물(UCC), 마이크로 블로그(Micro Blog) 5가지가 있다. 소셜 러닝은 넓게는 사람들이 소셜 미디어를 통해 서로 협업과 집단지성을 나누며 스스로 학습하는 것으로 좁게는 소셜 미디어를 통한 학습이라고 정의할 수 있다. 본 논문에서는 소셜 미디어와 Social Learning에 대해 자세히 알아보고 초등학교에서 어떻게 활용할 수 있는지 연구하였다.
