웹을 기반으로 하는 소셜네트워크서비스(SNS:Social Network Service)는 비약적 발전을 거듭하여 다양한 형태로 사용자에게 제공되고 있다. 관계/관심에 기반 한 서비스로 사람들의 참여와 관계에 의해서 Data가 쌓이고 이를 통해 다시 지속적인 참여와 관계를 유도하는 방식의 SNS는 웹을 기반으로 시작하여 모바일시장으로 확장되었다. 모바일 시장에서의 성공적인 SNS 사업모델의 개발은 모바일이 가지고 있는 사용자의 사용행태를 기반으로 한 서비스 창출에 그 요인이 있다고 볼 수 있다. 이러한 배경에서 TV를 활용한 SNS 개발이 IPTV 사업자를 중심으로 국내외에서 지속적으로 연구되고 있다. 하지만 SNS를 위해 필수적인 요소인 TV에서의 개인화는 TV의 공공적 성격에 의해 연구의 진행이 미진한 실정이다. 이 연구는 IPTV에서의 개인화 방안을 사용자 행태분석을 통해 연구하고자 한다. TV의 개별 사용자를 위한 개인화는 PC나 모바일 기기와의 개인화와는 다른 방식의 개인화를 요구한다. 따라서 개별, 가족구성원 그룹별, 가족구성원 전체별로 개인화의 유형을 분리하고 이에 대한 행태분석을 실시한 결과 공공재 성격이 강한 TV에서의 개인화는 크게 개인화의 정도, 개인화의 유형, 개인화의 표현방식, 개인화의 구성방식에 있어서 PC나 모바일 기기와 다른 차이점이 있었다.

Social networking service (SNS) is a service that allows people to share information, manage relationships with others, and express themselves on the Internet. The number of SNS users have increased explosively with the growth of mobile devices such as smartphones. As the influence of SNS has grown extensively, potential threats to privacy have also become pervasive. The purpose of this study is to empirically examine the main factors that affect users' intentions to use security functions provided by their SNS. The main theories for this study include the rational choice theory and the theory of planned behavior. This study has identified the factors that affect intention to use security functions. In addition, security function awareness and information security awareness are found to be important antecedents for intention to use security functions. The results of this study implies that when SNS providers develop security policies, they should consider the ways to improve users information security awareness and security function awareness simultaneously.

상호작용 속도의 증가는 과잉 관계(over-relations)의 문제가 나타날 수 있다. 과잉 관계로 인한 심리적, 시간적 부담으로 SNS에 대한 피로감을 느껴 SNS 이용을 기피하는 이용자들이 생기고 있다. SNS 피로감(fatigue), SNS 불안감(anxiety) 등 SNS 이용으로 인해 발생된 부작용에 관한 사항들은 'SNS 스트레스'라고 볼 수 있다. 본 연구에서는 SNS에 대한 부정적인 측면을 스트레스라는 관점에서 살펴보며, 스트레스의 발생 원인을 상호작용의 과잉에서 찾고자 한다. 본 연구는 페이스북 이용자들을 대상으로 총 261부를 분석에 활용하였다. SEM(Structural Equation Model) 분석 결과, 모든 연구가설이 채택되었다. 정보공유와 커뮤니케이션 모두 사회적 상호작용 과부하에 긍정적인 영향을 미쳤으며, 사회적 상호작용 과부하가 스트레스를 불러일으키는 것으로 나타났다. 본 연구는 실증적으로 SNS 피로감을 유발시키는 원인으로 상호작용성을 대입해 SNS가 가진 특징이 오히려 부정적인 결과를 초래할 수 있다는 것을 검증하였다는 점에서 의의가 있다.

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.

Purpose The study examined the key factors influencing the formation mechanism of SNS addiction. Based on the use and gratification theory, we considered relationship maintenance, perceived enjoyment, and self-expression as main desires to induce SNS addiction. The characteristics of SNS users were also considered as major factors affecting SNS addiction. In particular, self-control and subjective well-beings were considered to be prevention factors that could reduce SNS addiction, while SNS relational intimacy was considered to be a facilitator that would increase SNS addiction. Design/Methodology/Approach A structural equation modeling (SEM) method was used to test the theoretical framework based on a sample of 224 Facebook users who have used it more than 6 months. Confirmation factor analysis was conducted to check the reliability, convergent validity, and discriminant validity. Findings Relationship maintenance had a significant effect on self-disclosure intention and SNS addiction, respectively. Perceived enjoyment was significantly related to self-disclosure intention, while it was insignificantly associated with SNS addiction. However, self-expression was not significantly related to both self-disclosure intention and SNS addiction. Consistent with our expectations, both self-control and subjective well-beings had negative effects on SNS addiction. The analysis results found that SNS relational intimacy was positively related to SNS addiction.

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.

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.
