As social network service(SNS) has grown rapidly, the variety information being shared through SNS. However, the privacy of individuals can be violated due to the shared information through a SNS or the post written in the past at the SNS. Although, many researches concerned about it, they did not suggest key management and access control especially. In this paper, we propose the method for the protection of the message in SNS using access control and hash-chain.

대한민국 20대 총선, 영국의 유럽연합 탈퇴인 브렉시트, 트럼프와 힐러리의 대결인 미국 대선, 이 셋의 공통점은 언론의 예측과 다른 투표 결과가 나왔다는 점이다. 이러한 일련의 사건들로 인해, 각종 언론사에서 실시하고 있는 표본조사의 신뢰도에 대한 근본적 재검토의 필요성이 제기되고 있는 실정이다. 본 논문에서는 선거 후보자 지지율을 효율적이며 효과적으로 분석하기 위하여 SNS 감정분석을 제안한다. SNS 감정분석은 기존의 표본을 구하고 분석하는 방식보다 더 빠르게 표본 수집 및 분석이 가능하다. 또한 R프로그램과 구글을 이용하여 처리하기 때문에 기존 방식에 비하여 매우 저렴하다. 현재 언론사의 예측이 빗나가고 있는 시점에서 SNS 감정분석이 훌륭한 대안이 될 수 있을 것이다. 본 연구에서의 트래픽*감정분석 점수를 보았을 때, SNS 감정분석이 여론을 더 정확히 반영한다는 것을 증명한다.

Purpose The purpose of this study was to investigate the factors affecting the users' stress and using reluctant intention to use social network service(SNS). This study especially focused on stress of SNSs' user. Because SNS has led to negative effects such as invasion of privacy, addiction and social overload recently. In addition, adverse effects of SNS had caused SNSs' user to feel stress and fatigue. Design/methodology/approach This study developed hypotheses to empirically examine the factors that affect SNS users' stress and using reluctant intention. In order to verify research hypotheses, this study collected data from 362 users who currently use the SNS in Korea. Further, we used the smartPLS analysis. Findings The results of this study are as follows; First, reputation perception, unwanted relation burden, privacy concern, information overload and interaction overload had a significant positive effect on SNS users' stress. But international influence had no significant positive effect on SNS users' stress. Second, SNS users' stress had a significant positive effect on using reluctant intention. The results of this study provides theoretical foundations on the research for dark side of SNS and implies that SNS providers are in need of exerting an effort to minimize the negative aspects.

The purpose of this study is to identify the brand personality factors of SNS based on SNS consumers and to examine the effect of SNS brand personality factors on the recognition of mobile native ads in SNS. As a property of mobile native advertisement, research model is suggested by introducing information, reliability, entertainment, interferences, and interactivity as research variables. And SNS users were surveyed. Through the online survey, 341 copies were used for the analysis. According to the results of the analysis, five characteristics of SNS brand personality factors such as 'sincerity', 'enthusiasm', 'charm', 'practical', and 'community' were derived. Among these, 'sincerity', 'enthusiastic', and 'community' brand attributes have a positive effect on most of mobile native advertising attributes, but 'practical' brand characteristics negatively. The attractiveness of the brand was not related to the mobile native advertisement.

Continuous use of SNS with having SNS fatigue influences users mentally as well as physically. Although it is reported that they eventually leave SNS due to experience of fatigue, the determinants of SNS fatigue have not been discovered yet. Thus this study aims to find the psychological factors causing SNS fatigue. This study (1) found out the factors causing SNS fatigue, and (2) explored the relationships between the factors and intentions to discontinue/continue to use SNS. Findings of the study suggested that there are seven types of determinants: Sense of relative deprivation, Relationship concern, Management burden, Information overload, Privacy concern, Reputation concern(after posting), Reputation concern(before posting). It is also found that sense of relative deprivation negatively predicted the intention to keep using SNS while management burden, reputation concern(before posting) predicted positively. Furthermore, the sense of relative deprivation and information overload positively predicted the intention to discontinue using SNS while reputation concern(before posting) predicted negatively. This research examined how the determinants of SNS fatigue affect the intentions to keep/stop using SNS from the two different points of view. The determinants of SNS fatigue experienced by SNS viewers influenced them to have intentions to stop using it, whereas those felt by SNS writers affected them to keep using it.

This study aims at examining the ways which a school librarian uses SNS when performing tasks and the use of SNS with the features of the task and the organizational system run by one person affect task performance. In this study, for objective explanation of the interrelation among a librarian's tasks and the use of SNS and performance, the model of a Librarian's Task-SNS Technology Fit was suggested through the combination of the Technology Acceptance Model and the Task-Technology Fit. Based on the result of the survey analysis, their utilization of SNS is not just limited to personal taste nor interferes with their work. Rather, it enhances task performance owing to the characteristics of the tasks or the organization such as the organizational system run by one person.

Social Network Service is one of platforms rapidly growing in the environment of digital convergence. Most of researches regarding social network service(SNS) done up to the present time are concerning about technic and effectiveness characteristics of SNS. However, this study focuses on the roll of self-disclosure in the use of social network services(SNS). From the perspectives of personal and social motivation rather than the effectiveness and technic characteristics of SNS. the relations among self-disclosure, enjoyment, social ties and intention to use have been tested empirically. The results from this study shows that self-disclosure has not directly effects on the intention to use of SNS, but indirectly effects on it through personal enjoyment and desire to have social ties.

Owing to supply of smart phones and the diffusion of SNS, the number of peoples who are living, linked with us, is incomparably more than in the past. The continuous communication is essential in maintaining good relationship, so peoples have no choice but to seek for most efficient communication method in order to maintain good relationship. This thesis intended to advise how to construct next generation immersive multi-media system, using augmented reality and MPEG-V that have come to the fore recently. In addition, the SNS platform service of new type was suggested in this thesis, in connection with the pairing service. Now, we can create a town in a specific space like the real world, if we utilize the augmented reality that became possible by SNS service and we can talk and exchange informations in that space. This system would provide various services peoples wish to have, interlocking experiences through five senses like sense of vision, sense of hearing, sense of touch and etc..
