The development of Social Network Service (SNS) has brought many positive changes to the ways people communicate, interact and share information. However, using the SNS does not always leads to in a positive results, particularly when it is addictively used. In fact, the addictive use of SNS results in many negative effects in our society. Recently, SNS users feel negative emotions such as expecially stress and fatigue while using SNS. Thus, the purpose of this study is to empirically examine antecedents of user fatigue on SNS, which can be explained by the degree of Individual, environment and SNS characteristics. This study also examines consequences of user fatigue on SNS. Lastly, we examine the moderating effects of Habit among SNS fatigue, barrier of living and task performance decline. The data for empirical analysis were collected 401 responses on SNS users in Korea. The results of this study are as follows; First, reputation perception, loneliness, unwanted relation, privacy concern, information overload, social presence and interaction are significantly related to SNS fatigue. Second, SNS fatigue, barrier of living and Task performance decline are significantly related to discontinuous usage intention. Third, the moderating effect of Habit of SNS using is found in the relationship among SNS fatigue, barrier of living and task performance decline. Based on the results of this study, Theoretical and practical suggestions were discussed.

Purpose SNS (Social Network Service) is one of new promising marketing tools which allow marketer to do two-way communication and social interaction. Three characteristics of SNS marketing including informativeness, interactivity, and playfulness are distinguished from traditional marketing. The purpose of this study is to examine the relationships between three characteristics of SNS marketing, brand image, and purchase intention. Design/methodology/approach The present study proposed a research model integrating SNS marketing characteristics, brand image, and purchase intention represented by structural equation modelling and four hypotheses. A total of 20 questionnaire items for five variables were developed and measured by using five point Likert scale. 199 valid data were collected and used to test four hypotheses using SmartPLS. Findings Three hypotheses that the characteristics of SNS marketing such as informativeness, interactivity, and playfulness have a positive influence on brand image were supported at the significance level of 0.05 and 0.001 respectively. The hypothesis regarding the relationship between brand image and purchase intention was also supported at the significance level of 0.001. Brand image plays a significant mediating role in the relationship between SNS marketing and purchase intention. In particular, the result of research that playfulness of SNS marketing affects brand image significantly suggests a new future research theme regarding spiritual marketing. Implications for academics and practitioners were suggested.

최근 다양한 스마트폰이 개발 보급되면서 SNS(Social Network Service)를 사용하는 사용자 또한 급격히 증가하였다. SNS는 기존 모바일 기기에서 수집할 수 있었던 문자 및 통화내역과 같은 단순한 사용자 데이터 외에도 주고 받은 사진 및 동영상, 음성쪽지나 위치 공유, 대화 내역 등 다양한 정보가 저장되어 디지털 포렌식 관점에서 유용한 데이터 획득이 가능하다. 본 논문에서는 최근 많이 사용하고 있는 아이폰을 대상으로 스마트폰에서 이용할 수 있는 SNS 클라이언트와 각 클라이언트 별로 수집할 수 있는 데이터의 종류를 살펴본다. 또, 각 데이터간의 연관관계를 통해 수집된 데이터의 효율적인 분석 방법을 제시한다.

With the proliferation of smartphones and 5G networks, mobile social network service (SNS) has become an indispensable part of people's daily lives. However, with the use of SNS, fatigue and withdrawal behavior gradually emerged. Based on The Transactional Theory of Stress and Coping (TTSC), we explored the mechanism of SNS overload on users' discontinuous intention under the framework of "stressor-strain-outcome". And we also investigated the moderating effects of gender in this process. We hope that through our research, we can help SNS users to reduce unnecessary fatigue, and provide better suggestions for platform designers to adjust product design to improve user experience.

본 연구의 목적은 청소년 모바일 폰 이용의 심리적 특성 중 내적요인과 이용 동기를 알아보고자 이 연구를 실시하였다. 내적요인에서는 자기조절력, 이용 동기에서는 대인관계, 즐거움, 현실회피 성취 욕구를 알아보고자 함이다. 이 연구를 위해 한국정보화진흥원은 2018년 인터넷과 모바일 폰 중독의 장기 추적 자료 중 자기제어 및 이용자 동기대책에 근거한 568건의 자료를 활용하였다. 데이터 분석을 위해 SPSS 윈도우 23 버전을 사용했고, 수집된 데이터는 피험자의 인구학적 특성을 파악하기 위한 분석이었다, 또한 인체모형 변수를 분석하여 그룹 간 변수의 상관관계를 조사하였으며, 연구 결과는 다음과 같다. 첫째, 중독성은 소셜 네트워크서비스 (SNS) 집단보다 모바일 폰 게임 집단이 약간 높게 나타났으나, 이용 동기에서는 소셜 네트워크서비스 (SNS) 집단이 대인관계 욕구가 높게 나타났고. 현실회피 욕구에서는 모바일 폰 게임집단이 소셜 네트워크서비스 (SNS) 집단보다 높은 차이를 나타냈다. 그러나 즐거움 및 성취욕구 에서는 집단 간 차이가 없었다. 본 연구의 결과 모바일 폰 사용의 컨텐츠에 따라 모바일 폰 과다 사용에 영향을 미치는 요인에 차이가 있음을 시사 하였으며, 후속 연구에 대한 제안이 논의되었다.

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.

The online social networking services (SNS) have been growing as the means of communication. In this study, we investigated word-of-mouth (WOM) effect under the SNS environment and evaluated the impact of message sender's influence on the WOM effect. Especially, this study focused on the betweenness centrality calculated through the social network analysis (SNA) of SNS network information, and proposed it as the measure of WOM message sender's influence, SNA may provide more accurate and objective measures than subjective self-reporting survey method. Fifty-one Facebook users responded to each of their four Facebook friends, who had been selected based on their betweenness centrality, Statistical analyses were performed using the responses and the betweenness centralities of the Facebook friends. The results showed that the direction (positive vs, negative) of a WOM message in SNS had an impact on the attitude of the message receiver toward the product. Moreover, the betweenness centrality of the message sender as well as his/her opinion leadership had a moderating effect on the WOM effect. Opinion leadership is a measure that has been frequently used for indicating the influence of WOM message sender in the previous studies. Considering the result that the betweenness centrality of the message sender was Significantly correlated to his/her opinion leadership, the betweenness centrality can be used for indicating the influence of WOM message sender.

This study investigated the semantic network based on the focus of the fashion image and SNS text utilized by global SPA brands on the last seven years in terms of the quantity and quality of data generated by the fast-changing fashion trends and fashion content-based media environment. The research method relocated frequency, density and repetitive key words as well as visualized algorithms using the UCINET 6.347 program and the overall classification of the text related to fashion images on social networks used by global SPA brands. The conclusions of the study are as follows. A common aspect of global SPA brands is that by looking at the basis of text extraction on SNS, exposure through image of products is considered important for sales. The following is a discriminatory aspect of global SPA brands. First, ZARA consistently exposes marketing using a variety of professions and nationalities to SNS. Second, UNIQLO's correlation exposes its collaboration promotion to SNS while steadily exposing basic items. Third, in the case of H&M, some discriminatory results were found with other brands in connectivity with each cluster category that showed remarkably independent results.
