With the rapid development of Social Network Service and with the diversification of user needs, new types of image-based SNS have emerged. Image-based SNS provides customized service to meet users' specified contents needs that have yet to be satisfied in conventional relation-based SNS like Facebook, leading the trend of service diversification. Unlike text-based SNS that has inconvenient view on a small mobile screen, image-based SNS provides the communication way focused on simple text message and image, and thus the main users of the image-based SNS are young people in their 20s who get accustomed to images, rather than text messages. Accordingly, the functions and roles of SNS UI have varied, and usability has been more important. With the users in their 20s who use image-based SNS, this study tried to look into the usability of the image-based SNS. To do that, heuristic evaluation method was applied to find UI problems. The main factors constituting usability were extracted, and user evaluation method was redesigned. Aside from the satisfaction measurement, this study conducted and analyzed a questionnaire survey with users in their 20s who used actual image-based SNS. This study analyzed usability factors that influenced of image-based SNS users. The analysis results are considered to be used as a fundamental material to improve usability in the process of developing social media service.

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.

The purpose of this study is to empirically address the influences of motives for using SNS on relational bridging and relational bonding in SNS and motives for continuous use SNS by applying the concepts of bonding and bridging, defined in the social capital theory, and major motives for using SNS are classified into three categories-social, information, and recreation categories - based on the previous studies and the usage and gratification theories. Through this study, it was revealed that motives of all these three categories-social, information, and recreation categories-have significant influences over relational bridging and relational bonding in SNS while relational bridging and relational bonding in SNS have significant influences over consistent motives for using SNS so the hypothesis of this study is accepted. It was also proven that motives of all these three categories - social, information, and recreation categories-for using SNS are important factors for creating new communities or expand relationships with other SNS users sharing similar interests. In addition, it was found that SNS users constantly use SNS to build relationships that could create a strong bond between individuals and receive emotional supports when necessary and to expand its own network by creating new relationships with other SNS users.

SNS is a social networking service that helps people to have a two-way communication, manage their personal relationships and share information. The domestic and international SNS markets have attained a steady growth, and their growth is being more accelerated recently. Under these circumstances, immature students are more likely to show negative cyber behavior. This study attempted to analyze the relationship between the use of SNS, motives of SNS use, the use of active SNS functions, SNS-dependency and views in SNS and negative SNS behaviors among elementary and middle school students. For this, negative cycber behaviors are classified into four stages depending on the severity, for each of which distribution of factors is investigated and the combination of factors to determine each stage is obtained through association rule analysis. As a result, it is found that 85% of the students rarely show negative cyber behaviors, stealing personal information and contacting with strangers are the most frequent negative behaviors, and students with a great dependency on SNS are highly probable to show negative behaviors.

Relevant social costs are also becoming troublesome. SNS and gaming addictions have negative effects on one's life, causing significant social problems. To illustrate different facets of these addictions, Problem Behavior Theory is adopted in the study. How self-esteem and perceived family environment affect SNS addiction and gaming addiction is addressed.

The purpose of this study is to analyze the key factors affecting satisfaction of the visually impaired SNS users so that they may use SNS more effectively in the future. This study has used three factors such as the information factor, the relationship factor and the speed factor and the usability as independent variables. The social presence factor was used as a parameter and the SNS user satisfaction as a dependent variable. For the research, 195 visually impaired SNS users have participated in this survey. The major findings of this study are that the relationship factor has strong effects on the self-identification factor, the social presence factor and the SNS usage satisfaction among the factors affecting the visually impaired users to be satisfied with SNS. On the other hand, the information factor and usage factor have no effects on the self-identification factor and the social presence factor. However, they have effects on the SNS usage satisfaction. Additionally, the self-identification factor has no effect on the SNS usage satisfaction, but the social presence factor has effect. Based on the above study results, this paper proposed for the government to enhance the educational program on the use of SNS for the visually impaired and to increase its financial and political support on this subject. Additionally, technical supports on SNS service accessibility and usage by the government are vital for the visually impaired. Academically, this study provides a concrete groundwork for the research on the use of SNS by the visually impaired by providing a solid research direction for further study on this subject. Socially, this study helps the visually impaired use SNS more effectively by increasing the general public awareness of the importance of SNS usages by the visually impaired so that the information gap of the society may be diminished in the future.

The purpose of this study was to investigate the relationship between demographic characteristics, self - esteem, and attachment instability (attachment anxiety, attachment avoidance) in the college students' SNS addiction tendency. To investigate the influencing factors on SNS addiction tendency of college students, we surveyed 330 college students at universities in the metropolitan area through offline and online questionnaires, and analyzed 271 valid ones. Frequency analysis, descriptive statistics, variance analysis, Pearson correlation analysis and multiple regression analysis were performed. The results of the analysis are as follows. First, 87.4% of college students used SNS, and the most used SNS was 'Facebook (82.3%)'. The most frequent use of SNS per day was 'over 1 hour ~ less than 2 hours (24.7%)'. Second, women had a significantly higher SNS addiction tendency than men. Third, self-esteem and SNS addiction tendency showed significant negative correlation. Fourth, attachment anxiety and attachment avoidance were positively correlated with SNS addiction tendency. Fifth, the self-esteem of college students affects negatively on the SNS addiction tendency and only the attachment anxiety among attachment instability affects the addiction tendency. Finally, we discussed the risk of SNS addiction according to the characteristics of university students.
