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.

The purpose of this study was to verify the effects of two types of social capital on trust and purchase intention of food products. In addition, the moderating roles of perceived risk and SNS receiver characteristics were also examined. The survey for this study was conducted from the 17th to the 30th of June, 2016 through SNS using the convenience sampling method. A total of 230 responses were collected, of which 200 were used for analysis, after excluding responses containing missing data. Multiple regression and moderated regression were conducted to verify the hypotheses. The results from this study are as follows. First, it was found that social capital (bridging social capital and bonding social capital) had an effect on trust of food product. Second, perceived risk of food product was found to moderate the relationship between social capital (bridging social capital and bonding social capital) and trust. Third, trust of food product significantly impacted purchase intention. Fourth, SNS receiver characteristics of food product were found to moderate the relationship between trust and intention;, and trust of food product was found to mediate the relationship between bridging social capital and purchase intention.

This study is a descriptive research study to find out the relationship between degree of Self-Esteem, Anger-Out, Anger-In, Anger-Control and SNS Addiction Tendency of high school students, and the factors that influence SNS addiction tendency. For a total of 10 days from May 18 to 28, 2020, a total of 100 people were collected using online questionnaires to those who were attending high schools in S and G regions and using SNS. As a result of the study, SNS addiction tendency and self-esteem(r=.385, p<.001), anger-control(r=-.354, p<.001) showed a normal inverse correlation, and an anger-out (r=.321, p=.001), anger-in (r=308, p=.002) showed a common net correlation. Factors affecting SNS addiction tendencies were self-esteem(β=-.297, p=.001), gender(β=.266, p=.003), and anger-out(β=.247, p=.007), with 27.7% explanatory power in the regression model(F=12.279, p<.001). Therefore, it is necessary to develop programs to increase high school students' self-esteem and lower their anger-out in order to reduce SNS addiction tendencies, especially for female high school students in gender.

Among those, 490 were collected, and 478 were used for analysis excluding those with no answer or insincere answers. Results - SNS word of mouth information characteristics had significant effects on trust of restaurant product in the order of vividness, neutrality, and timing. Trust on restaurant product has significant effect on perceived risks (-) and perceived benefits (+) by SNS. While perceived benefits of restaurant product on SNS has effect on purchase intention, perceived risks of restaurant product on SNS does not affect purchase intention. Perceived benefits of restaurant product on SNS has significant effect on word of mouth intention, whereas perceived risks of restaurant product on SNS does not have significant effect on word of mouth intention. Conclusions - As marketing through SNS can bring about a huge reduction effect in terms of marking cost, it can be utilized as an effective promotion by not only large restaurant corporations, but also small restaurants.

Social Networking Service (SNS) is a part of our daily lives, with their positive and negative impacts. This study investigates SNS fatigue in men and women of different cultural backgrounds as well as the relationship between SNS fatigue and the intentions to cease SNS activities. The study results show that during SNS activities, women are more concerned for their reputation; participants with East Asian cultural backgrounds experience burdens with respect to relationships, and participants with Western cultural backgrounds experience fatigue with respect to privacy concerns. No statistical significance was identified between SNS fatigue and the intentions to cease SNS activity; although people experienced fatigue, they did not desire to stop SNS use. This study reveals that culture and gender impacts SNS fatigue, and few people quit SNS despite the fatigue.

This study was conducted to examine SNS addiction proneness and interpersonal satisfaction among undergraduate students and the relationships between these two variables, as well as to establish baseline data for appropriate intervention of SNS addiction prevention. The participants of this study were 316 undergraduate students in D and K city, and data were collected between June 30 and July 30, 2017. Data were collected by a self-administered online survey and analyzed by descriptive statistics, t-tests, and Pearson's correlation coefficients using SPSS. The results showed that SNS addiction proneness and interpersonal satisfaction were negatively correlated (r=-0.57, p<0.01), indicating students with higher SNS addiction had lower interpersonal satisfaction. There were no significant differences in SNS addiction proneness and interpersonal satisfaction by gender (t=0.05, p=0.963), number of SNS networks (t=0.66, p=0.513), or number of SNS-only networks (t=-1.24, p=0.216). Students who used SNS for data collection showed significantly higher interpersonal satisfaction (t=3.02, p=0.030); however, there was no significant differences in SNS addiction proneness among purposes for using SNS (t=0.39, p=.759). The results of this study will be useful baseline data for developing an intervention to improve interpersonal satisfaction and prevent SNS addiction among undergraduate students.

The number of customers on Social Network Services(SNS) is rapidly increasing with the spread of smartphones. As of 2018, about 2.7 billion people of the world population (about 7.1 billion people) and more than 31.2 million people of the total population of South Korea (about 50.1 million) use SNS. There are several studies have been conducted on increasing SNS market. Most of them, however, were not quantitative but qualitative studies. This study is conducted on domestic SNS market to identify the competitive relationship among SNS platforms with great proportion in South Korea, such as Facebook, Instagram and Twitter. The objective is to suggest some hypotheses of the competitive relations, test them, and finally verify the trend of domestic SNS market. Competitive Lotka-Volterra (LV) model is used to find out the competitive relationships and Moving Window is also used to show the changes of them over time. In order to test the hypotheses on the relationships, some experiments are performed with Moving Window technique. Thus, the relations among the platforms and the changes of them over time are identified.

The present study sought to identify the differences in levels of depression and impulsivity depending on hours on SNS among Korean adolescents. Data for this study was collected from the responses of 1,008 of middle and high school students in Seoul in 2014. The upper 33%(N=364) and the lower 33%(N=319) of students who reported to spend lots of time on SNS were extracted from the total data to constitute two groups for analysis. The sample was analyzed utilizing SEM to compare depression and impulsivity levels of the upper group with those of the lower group while controlling for gender. In conclusion, there was a significant difference in level of depression and impulsivity between the two groups. The upper group that spent more time on SNS displayed higher levels of depression and impulsivity. The result of this study means that the more time the adolescents spend on SNS the more likely the adolescents are to be depressed and impulsive.

Due to tough competition among social network services, technological specification alone could not be an adoption factor by the users. Instead, emotional factors such as a brand image and feeling towards an SNS brand became important factors in service differentiation. This study examined Korean young users perception of brand personalities of three social network services, Facebook, Kakao Story, and Band. It also analyzed the influence of the perception of brand personality, brand-self-image congruence, and brand affect on brand recommendation to others. The authors conducted a survey of Korean college students. The results indicate that SNS users perceived three SNS's brand personalities differently, and the positive perception of an SNS service has a positive effect on brand recommendation. Brand personality, brand-self-image congruence, and brand affect combined determine brand recommendation. When the brand personality variable is statistically controlled, brand affect has strong effect on brand recommendation.
