In the last few years, a new type of synchronous social networking services (SNSs) has emerged—social live streaming services (SLSSs). Studying SLSSs is a new and exciting research field in information science. What information behaviors do users of live streaming platforms exhibit? In our empirical study we analyzed information production behavior (i.e., broadcasting) as well as information reception behavior (watching streams and commenting on them). We conducted two quantitative investigations, namely an online survey with YouNow users (N = 123) and observations of live streams on YouNow (N = 434). YouNow is a service with video streams mostly made by adolescents for adolescents. YouNow users like to watch streams, to chat while watching, and to reward performers by using emoticons. While broadcasting, there is no anonymity (as in nearly all other WWW services). Synchronous SNSs remind us of the film The Truman Show, as anyone has the chance to consciously broadcast his or her own life real-time.

A new communication revolution such as social networking service (SNS) has been transforming the way of interaction between people in both of individual level and organizational level. Recently many people have switched to closed type SNS such as Naver Band and Kakao group due to the several reasons. The purpose of this study is to investigate the usage motivation and satisfaction of SNS based on use and gratifications perspectives. Based on prior studies on use and gratifications of Internet-related media and SNS, information motivation, relationship motivation, pleasure/entertainment motivation, self-expression motivation, work motivation were identified as usage motivation of SNS. This empirical study explores how these motivations vary between open type SNS(facebook and twitter) and closed type SNS(band and kakao group). This study contributes to provide the base of activation strategies and practical implications for companies using SNS as a marketing tool.

Nowadays, owing to the diffusion of smartphones and the growth of social networking services (SNS), the number of people who share their life with other SNS users by posting photos is increasing. The number of Instagram users has been particularly increasing since Instagram started its service in 2010. Compared to other SNS such as Facebook and Twitter, Instagram runs its service by focusing solely on photos, which is a major differentiation factor compared with other existing SNS. Previous studies, however, do not examine SNS that focus on photo sharing adequately. Therefore, we establish a hypothesis relating to the motivations behind a user's photo sharing attitude and posting intention through Instagram. Moreover, this will be achieved by employing TRA(Theory of Reasoned Action) and focusing on intrinsic and extrinsic motivations. The analysis results show that intrinsic motivation influences a user's sharing attitude and subjective norms. Apart from this, Instagram's expressivity influences a user's photo sharing attitude and posting intention.

Recently, with the growing of social network sites, people's choice is also getting more and more. So the notion of loyalty has become an important construct within the Social Network framework because of member is easy switching on the social networking sites. Despite the increasing importance of social network sites loyalty question, there's very little research in this area. In electronic commerce, the website loyalty development process is based on both website satisfaction and website trust toward the net-enabled business. But how to target the members with high or low loyalty in the social network sites is still a question. In this paper we propose one improved RFM model to evaluate the member loyalty to find the potential members for improving the service quality of the social network site. In addition, an empirical case study is performed to demonstrate how this procedure works. Moreover, further applications of this research are provided for improved social network sites experiences and how to use the model to practice.

SNS(Social Networking Services) is oneline service that enable users to construct human network through their relation on web, such as following relation, friend relation, and etc. Recently, owing to the advent of digital devices (smart phone, tablet PC) which embedded GPS some applications which provide services with spatial relevance and social relevance have been released. Such an online service is called LBSNS. It is required to use spatial filtering so as to build the LBSNS system that enable users to subscribe information of interesting area. For spatial filtering, user and tweet attaches location information which divide into static property presenting fixed area and dynamic property presenting user's area changed along the moving user. In the case of using a location information including dynamic property, Continuous query occurred from the moving user causes the problem in server. In this paper, we propose spatial filtering algorithm using Virtual Grid for reducing frequency of query, and conclude that frequency of query on using Virtual Grid is 93% decreased than frequency of query on not using Virtual Grid.

Recently, Due to advances in smart-phones and mobile devices, the use of SNS is increasing in recent years. Online networking is building new paradigms in terms of creating personal needs. Along with the nature of mobile devices, it is expected to have a lot of impact on SNS service participation. The study focused on the effect of SNS on SNS participation and ease of use of social characteristics and ease of use of SNS. A survey was conducted on a survey of SNS users and analyzed the data through the structural equations. The study found that the study of social networking was statistically significant in terms of the intent of identifying the usefulness of SNS and ease of use and ease of use.

The aim of this research is to design and analyze a social network service model using mobile RFID based business card. This paper suggests how the behavior of exchanging business cards will be changed in ubiquitous environment and designs a social networking service model using a ubiquitous business card, which embeds a RFID tag. We describe the scenarios and analyze a role, value and potential benefits of participants of the u-SNS service model. For the proof of the superiority and the feasibility of our model, we compare it with its related researches and products based on the calculation of the benefits and costs of the alternatives.

The purpose of this study was to examine the structural relationships among the motives on Social Networking Service(SNS) of restaurants customers, attitude toward SNS, and intention to use. Using a quota sampling method, data were collected from 273 residents of the whole country who were in their 10~50s. The PASW Statistics 18.0 and AMOS 17.0 statistical package were used for the analysis. The hypothesized relationships of the model were tested simultaneously using a structural equation model(SEM). The proposed model provided an adequate fit to the data, ${\chi}^2$=287.558(df=155) p<.000, CMIN/df=1.855 GFI=0.905 NFI=0.887, IFI=0.944, TLI=0.931, CFI=0.943, RMSEA=0.056, RMR=0.025. The results showed that recreational motive(${\beta}$=0.238) and functional motive(${\beta}$=0.467) had a positive effect on the attitude toward SNS. Attitude had a positive effect on the intention of using SNS. The results enable the marketers of restaurants to develop SNS marketing strategies that motivate customers.

This paper examines the rising value of social networked journalism and analyzes the case of a social news site based on the theory of networked journalism. Social networked journalism allows the public to be involved in every aspect of journalism production through crowd-sourcing and interactivity. The networking effect with the public is driving journalism to transform into a more open, more networked and more responsive venue. "wikitree" is a social networking news service on which anybody can write news and disseminate it via Facebook and Twitter. It is operated as an open sourced program which incorporates "Google Translate" to automatically convert all its content, enabling any global citizen with an Internet access to contribute news production and share either their own creative contents or generated contents from other sources. Since its inception, "wikitree global" site has been expanding its coverage rapidly with access points arising from 160 countries. Analyzing its international coverage by country and by news category as well as by the unique visit numbers via SNS, the results of the case study imply that networking with the global public can enhance news traffic to the social news site as well as to specific news items. The results also suggest that the utilization of Twitter and Facebook in social networked journalism can break the boundary between local and global public by extending news-gathering ability while growing audience's interest in the site, and engender a feasible business model for a local online journalism.

Objectives: The purpose of this study was to identify a regional difference among drinking behaviors, sober motivation, and drinking problems. Methods: The subjects included 600 citizens living in two regions, Busan. Descriptive analysis, t-test, correlation, and path analysis were used to confirm the regional difference. Results: The path of drinking method on sober motivation was statistically significant in both regions and drinking attitude was found to be a common factor that weakens an individual's sober motivation. Besides, the path of social networking on sober motivation had a difference in statistical significance between the two regions. Finally, the influence of social networks of District N (comparison region) on sober motivation was statistically significant and stronger than that of District D. Conclusions: A social environment-centered intervention to address drinking problems is essential in District N because of its people's tendency to drink together. On the other hand, an individual-focused intervention is preferred in District D where sober motivation is mainly affected by drinking method and attitude.
