The purpose of this study was to investigate the influence of SNS addiction tendency, depression, and communication skill among university students. Subjects were 200 associate nursing students in Korea. The data were collected using a self-reporting questionnaire from October 11 to November 24, 2016. Data were analyzed by descriptive statistics, t-test, ANOVA, LSD test, Pearson's correlation coefficients, and multiple regression analysis using the SPSS/WIN 23.0 program. The levels of SNS addiction tendency were dependent on age (t=2.47, p=.044), connection SNS time (F=10.20, p<.001), and place of SNS use (t=2.54, p=.012). SNS addiction tendency was significantly correlated with depression. Higher SNS addiction was associated with higher rates of depression. SNS addiction tendency was not significantly correlated with communication skill in nursing students. Influential factors that affect SNS addiction tendency were depression (${\beta}=.265$, p<.001) and SNS usage time (${\beta}=.265$, p<.001), which explains about 15.5% of the variance. The results of this study indicate that nursing interventions are necessary to improve SNS addiction tendency, and early screening of nursing students is needed to develop health promotion programs for the vulnerable.

Purpose: The purpose of this study is to identify the mediating effects of self-esteem between social comparison orientation and social network service (SNS) addiction in university students. Methods: Descriptive cross-sectional survey design was employed. The data were statistically analyzed by using the descriptive and inferential statistics. Sobel test and Bootstrap method, and Kappa squared mediation effect size measure were used to identify the mediator's significance. A convenience sample of 195 subjects was recruited from two universities in Korea. Results: The mean age of the subjects was $22.58{\pm}1.81$. The subjects showed relatively high levels of SNS addiction with a mean score of $14.33{\pm}4.80$. The overall model significantly explained 37.0% of variances in the subjects' SNS addiction after controlling gender, age, grade, major, period of SNS using, time spent on SNS per day, and times accessed SNS per day. Of the predictors, time spent on SNS per day, social comparison orientation, and self-esteem were significantly associated with SNS addiction. Self-esteem was the mediator between social comparison orientation and SNS addiction. Conclusion: When developing strategies for preventing SNS addiction, interventions for reducing time spent on SNS per day, not having upward social comparison orientation, and improving the self-esteem should be considered. These findings might provide a theoretical basis for developing effective strategies for preventing SNS addiction in university students.

This study confirmed the moderating effect of online social support on the rejection sensitivity and SNS addiction tendency of adults. For this purpose, a survey was conducted using the SNS addiction propensity scale, rejection sensitivity scale, and online social support scale targeting 486 adults nationwide. The collected data were analyzed using SPSS 27 and PROCESS Macro 3.5. As a result of this study, first, SNS addiction tendency, rejection sensitivity, and online social support were all positively correlated. Second, in the relationship between rejection sensitivity and SNS addiction tendency, online social support showed a moderating effect in the male group. The results of this study are significant in that they confirmed the importance of rejection sensitivity and online social support in confirming the tendency of SNS addiction in male and female groups. Based on these results, the limitations of this study and suggestions for follow-up studies were presented.

The present study explored the moderating roles of perceived responsiveness of SNS friends and self-esteem in the relationship between SNS use and perceived social support among college students. Using a panel owned by a research firm, a nationwide online survey was conducted (females N = 264, males N = 239). The results of regression analysis suggested that there is no significant main effect of SNS use but a significant main effect of perceived responsiveness of SNS friends. In addition, a three-way interaction effect was found among perceived responsiveness of SNS friends, SNS use, and self-esteem. This study contributes to elaboration of the extant research as well as providing practical implications to SNS-based intervention programs for college students' psychological well-being.

SNS is a social networking service that removes the barrier between cyber spaces and the real world and helps people who have common interests to have a two-way communication, manage their interpersonal relationships and share information. The domestic and international SNS markets have attained a steady growth, and their growth is being more accelerated in recent days. However, studies on SNS have just examined adults, and it's required to research the use of SNS and cyber behaviors via SNS among elementary and middle school students. This study attempted to analyze the relationship of the use of SNS, motivation of using SNS, the use of active SNS functions, SNS-dependent tendency and SNS awareness to cyber behaviors via SNS among elementary and middle school students. As a result, regardless of gender and grade, stealing private information was the most frequent activity and the frequency of 'contacting strangers' activity increased most rapidly with the usage time and grade. SNS dependency turned out to be the most highly correlated with the negative cyber behavior. Moreover, the difference of gender was not significant to the overall negative cyber behavior, whereas that of grade was.

The dramatic growth of social networking sites (SNS) has created a myriad of privacy concerns. Our study focuses on how much monetary incentive SNS users are willing to accept in exchange for disclosing their SNS information by accepting friend requests. First, we focused on information privacy in SNS, and estimated the value of information privacy by using the contingent valuation method. Second, we attempted to estimate how SNS users' willingness to accept would change when demographic information and additional information vary. Privacy-sensitive SNS users have the following characteristics: higher education, less SNS experience, and higher security consciousness. On the contrary, those who make good use of SNS and use open-based SNS are less sensitive to privacy. In summary, privacy-sensitive SNS users are fearful or uneasy when they have insufficient control of SNS information. Considering 14 conditions on the value of information privacy on SNS, the mean value of SNS information per person is 173,957 won. If we apply this value to Facebook users, the total Facebook information value would be 1.91 trillion won, considering that there are 11 million users in Korea.

Purpose Social Network Service (SNS) users feel fatigue in process of using open type of SNS like Facebook and Twitter. Compared to the open SNS, the closed SNS takes an closed form to prevent privacy exposure, and they are more practical and advantageous to form deeper social relationships. This study attempt to examine the effects of the mobile closed SNS characteristics (such as usefulness, playfulness, perceived security, psychological privacy, social influence, and belonging) on the users' continuous SNS usage intention. Design/methodology/approach This study used a mixed methodology combining in-depth interviews and empirical validation to investigate the effects of the mobile closed SNS characteristics on the continuous SNS usage intention of users. Findings Analytical results from a survey of 210 mobile closed SNS users showed that except perceived security, the effects of the five SNS characteristics on continuous SNS usage intention were significant. These findings contribute to improving the quality of mobile closed SNS services and suggesting SNS related marketing strategies.
