In the past, crime prediction methods utilized previous records to accurately predict crime occurrences. Yet these crime prediction models had difficulty in updating immense data. To enhance the crime prediction methods, some approaches used social network service (SNS) data in crime prediction studies, but the relationship between SNS data and crime records has not been studied thoroughly. Hence, in this paper, we analyze the relationship between SNS data and criminal occurrences in the perspective of crime prediction. Using Latent Dirichlet Allocation (LDA), we extract tweets that included any words regarding criminal occurrences and analyze the changes in tweet frequency according to the crime records. We then calculate the number of tweets including crime related words and investigate accordingly depending on crime occurrences. Our experimental results demonstrate that there is a difference in crime related tweet occurrences when criminal activity occurs. Moreover, our results show that SNS data analysis will be helpful in crime prediction model as there are certain patterns in tweet occurrences before and after the crime.

This study investigates SNS usage behaviors of SNS users with a change of SNS use environment and an increase of users. This study compares the difference of use motivation, preferred type, and main use SNS according to socio-demographic variable of SNS users using cross tabulation analysis and also conducts a comparative analysis of main use SNS of each SNS user using correspondence analysis. The results show main use motivation of SNS is relationship seek, most preferred type is closed type, and main use SNS is Kakaostory. Next, we find that there are differences on use motivation, preferred type, and main use SNS, depending on the socio-demographic characteristics of SNS users. The result of correspondence analysis shows how users are using SNS services and what structure their competitive relations of SNS services are made. In the conclusion, the study presents summary of the findings, implications, and tasks for further studies.

The purpose of this study is to investigate whether there is a need to adopt new media usage variables as additional demographic variables. For the study, 500 Daejeon citizens were surveyed in July 2011 and the results were analyzed. It was confirmed that demographic variables such as gender, age and income still have effective explanatory power, but the explained variance of dependent variables was not stable. Regression analysis with the addition of new media usage variables(internet, SNS, smart phone) showed a significant increase in explained variables in three out of ten issues(global warming, use of public transportation, support of the current administration's national policies). Although the new media usage variables failed to consistently explain variance on several issues, they may be necessary to understand the public support of national policy or new agenda like global warming.

SNS의 다양한 역기능과 함께 중독문제가 사회적 문제로 대두되고 있는 가운데 이미지 기반의 인스타그램이 강세를 보인다. 이에 본 연구는 SNS중에서 이용도가 높은 인스타그램 사용제한 시 사용자의 감정에 미치는 영향과 대안 활동을 파악하기 위한 목적으로 수행되었다. 실험 방법은 인스타그램 1일 5회 이상 이용자 3명을 대상으로 7일간 앱 삭제 및 이용을 제한하고 매일 1인칭 관찰기법인 자기 일기 작성으로 감정변화와 대안 활동을 수집했다. 본 연구의 결과는 사용 빈도수가 높을수록 시간이 흘러도 부정적 감정이 감소하지 않았고 사용 빈도수가 낮을수록 부정적 감정이 점차 감소하였다. 대안 활동으로는 오프라인 활동보다는 온라인 활동이 많았고 여러 종류의 스마트폰 미디어 활동을 한 것으로 나타났다. 이 연구는 나아가 의존도에 따라 부정적 감정소강 소요 시간을 측정하는 연구로 발전될 것을 기대하며 이에 따라 SNS중독성 해결에 필요한 시간, 대안 활동 제시의 연구 초석이 되길 기대한다.

Social Networking Sites (hereafter SNSs) have become a part of people's daily routines. Beginning as a hobby/communicating tool for a specific group of people, SNSs have expanded in terms of the number of users, frequency of access, and depth and range of sharing. It is recently reported that the users experience SNS fatigue from being connected at all time. However, limited research has addressed this issue. The purpose of the present study was to examine the mediating role of reputational concern and expectation of others' responses on the relationship between narcissism and Facebook fatigue. A total of 329 Facebook users completed an online survey. The results showed that individuals who rated high on narcissism experienced a high level of Facebook fatigue, and that both reputational concern and expectation of others' responses partially mediated the relationship between narcissism and fatigue. Implications of the findings and suggestions for future research are discussed.

This is a longitudinal study which aims to examine the effects of the use frequency of SNS on adolescents' stress and the relationship between the former and the latter, based on big five personality factors. To this end, the valid data of 994 adolescents were collected by administering questionnaires to the cohort groups of those using Facebook twice for one year(T1-T2). An analysis of the data showed that the use frequency of Facebook(T1) had no direct effects on stress(T2), and that there was an interaction between users' personality and the use frequency. In particular, users' stress(T2) was varied depending on neuroticism among personality factors, as the use frequency of Facebook(T1) increased. The higher the use frequency of Facebook, the more the stress in the group with weak neuroticism, while the higher the use frequency of Facebook, the less the stress in other group with strong neuroticism, probably because each group has different motivation for meeting their needs for social support: the former's stress may increase, since they has relatively lower needs for social support and face more conflicts as they more frequently use Facebook, while the latter's stress may decrease, because they have relatively stronger needs for social support and are likely to acquire psychological support, as they more frequently use it.

This study was performed to identify the relationship between the SNS addiction tendency, self-assertiveness and interpersonal problems in college students. The subjects consisted of 198 students in Korea. The data were collected using a self-report questionnaire from September 10 to 12, 2013. The data were analyzed by frequency, t-test, ANOVA, and Pearson's correlation using SPSS for Windows version 22. The SNS addiction tendency was significantly negatively correlated with self-assertiveness(r=-.148, p<.05) and significantly positively correlated with interpersonal problems (r=.434, p<.001). Self-assertiveness was significantly negatively correlated with interpersonal problems (r=-.459, p<.001). The higher the SNS addiction tendency, the lower the self-assertiveness and the higher the interpersonal problems. The lower the self-assertiveness, the higher the interpersonal problems. Therefore, to decrease the SNS addiction tendency, increase the self-assertiveness and decrease the interpersonal problems, it is necessary to develop and test program.
