The purpose of this study aimed to investigate the gender differences in the mediating effects of perceived social support and negative comparison in the relation between social networking sites and depression. For this analysis, 483 samples were collected and conducted by multi-group structural equation model. The findings of this study were as follows: (1) Collective identity was observed both in Facebook and in Internet Cafe activities. (2) Collective identity was positively related to perceived social support, but perceived social support was negatively related to depression. Also, negative comparison was positively related to depression. (3) In terms of gender differences, the Facebook activities were negatively related to depression for male while the internet cafe activities were positively related to depression for female. Lastly, (4) The collective identity was positively related to negative comparison for female.

This study examines the feelings of positivity and negativity generated through upward social comparison and explores the impact of the results of the emotions on SNS users' posting behavior. In particular, this study aims to systematically identify the influence of upward social comparison on SNS followers and uploaders' SNS usage behavior and the structural principle of social network circulation in which followers become uploaders again. According to the analysis, interaction-oriented followers made negative upward social comparison and positive upward social comparison, while negative upward social comparison reduced the publication of independence tendency. However, positive upward social comparison has been shown to increase both independent and interactive postings. The results of this study are meaningful in that SNS has expanded the results of prior studies, in which social comparison theories were biased toward negative upward comparisons, to positive upward comparisons. In addition, this study suggested a practical strategy for SNS platform operators on how SNS users would not deviate from other platforms.

Purpose Today, world-wide societies share their daily life and many communities exchange their information through the explosive developed SNS and the social media systems. However, many SNS fatigue related factors forced the discontinuance of SNS. This paper is aim to examine effect of SNS feature and negative emotion to figure out the reason of SNS discontinuance. This is verifying the effect of maintenance of SNS, security concern and psychological concern on SNS fatigue and the effect of upward/lateral comparison on negative emotion. Moreover, the effect of SNS fatigue and negative concern on the SNS discontinuance intention was examined. Design/methodology/approach This research used to the survey method to test its hypotheses and the survey population is Facebook SNS users. A software tool called AMOS 18 is used to analyze the structural equation model. Findings The results showed that maintenance of SNS, security concern and psychological concern had a positive effect on SNS fatigue respectively and upward/lateral comparison did on negative emotion. In addition, SNS fatigue and negative emotion had significant effect on discontinuance intention.

Previous research has empirically demonstrated the negative effects of social media use on young people's psychological well-being. Unlike most previous studies that focused on either Facebook or Instagram, this study comparatively examined the differences in upward comparison and its effects on self-esteem, life satisfaction, and depression between Facebook and Instagram. An analysis of survey data from 641 Korean college students, who reportedly use these two social media more actively than any other age group, found that college students experience more upward comparisons on Instagram than on Facebook. Upward comparisons on both Facebook and Instagram increased by college students' age and weekly usage time. Upward comparisons on Instagram increased by the additional factors of gender (females more than males) and number of "followings." Subsequently, the effects of upward comparison on psychological well-being were found to differ by social media platform. Upward comparisons were found to negatively impact all determinants of psychological well-being only on Instagram, but not on Facebook. The differences in upward comparison and its impact on young users' psychological well-being found in this study were discussed in terms of the different functional characteristics of the two social media platforms, which provides direction for further research needed to establish guidelines for healthy social media use by young people.

Purpose The purpose of this study is to investigate the factors which affect users' fatigue and reluctant intention of using a SNS. In particular, this study focused on the fatigue of SNS users, as the recent excessive use of SNS has led to negative effects such as invasion of privacy, addition and social overload. fatigue This research will explain how producing adverse effects by using SNS caused psychological and mental depression. Previous researches explained that mental fatigue associated with SNS is not simple one and it is complicated with various psychological factors. Considering this fact, this study introduced a behavioral economics concept and a social comparison theory in the research model. Design/methodology/approach For research purposes, this study developed research hypotheses in order to empirically examine the factors that affect SNS users' fatigue and reluctant intention. The empirical research was based on a poll done through 800 research candidates in the SNS fields and the final 451 responses were collected and used in statistical data analysis. The adaptability, trust, and validity to measurement model were verified and the structural relationship in the research model was analyzed through these 451 responses. Findings First of all, maintenance fatigue of SNS had a positive significant effect on coupling and fatigue of SNS and information privacy had a non-significant effect on fatigue. Second, coupling had a negative significant effect on rational inattention, however, perceived cost had a non-significant effect on rational inattention. Third, lateral/upward comparison had a positive significant on user's negative emotions. Meanwhile, user's negative emotions did not have a significant effect on rational inattention.

We systematically investigated the negative-refraction effect for both TE and TM polarizations in annular photonic crystals. Since two polarization waves are excited in different bands, they result in different refractive angles, and so polarization beam splitters can be made of annular photonic crystals. It was found that, in comparison to normal square-lattice air-hole photonic crystals, annular photonic crystals have a much wider common frequency band between TE-1 and TM-2, which is quite beneficial to finding the overlap between the negative-refraction regions belonging to TE-1 and TM-2 respectively. Further analyses of equifrequency surfaces and the electric-field distribution of annular photonic crystals with different parameters have not only demonstrated how the filling factor of annular cells affects the formation of the common negative-refraction region between TE-1 and TM-2, but also revealed some ways to improve the performance of a polarization beam splitter based on the negative-refraction effect in an annular photonic crystal.

If is interested and create rule between it in item that association rules buys, by negative association rules is interested to item that do not buy, it is attempt to do data Maining more effectively. It is difficult that existent methods to find negative association rules find one part of rule, or negative association rules because use more complicated algorithm than algorithm that find association rules. Therefore, this paper presents method to create negative association rules by simpler process using Boolean Analyzer that use dependency between items. And as Boolean Analyzer through an experiment, show that can find negative association rules and more various rule through comparison with other algorithm.

Social Networking Sites (SNS) provide people with unique online social interaction environments where users can disclose their thoughts, feelings, and opinions to their personal contacts. Although previous studies have suggested that such activities produce positive effects on SNS user well-being, this study considered potential negative effects by investigating the relationship between SNS use and depression. In particular, This stydy examined how specific activities are related to different types of social comparison (upward/downward/horizontal) and how these different types of social comparison influence depressed moods among college students. The analysis of a survey of 245 Instagram users found that (1) looking at other people's status updates and commenting on other people's photos influences upward social comparison, (2) frequency of Instagram use predicts upward/downward/horizontal social comparison, and (3) upward social comparison was postively associated with depression, while downward social comparison was negatively associated with depression. Furthermore, the path anlaysis show that social comparison mediates the effect of Instagram use on depression. It suggests that Instagram use does not directly increase depression but it can lead to depression when social comparison on Instagram triggers depression.

The present study examines whether fear of negative evaluation, social comparison and self-criticism mediate the relationship between insecure attachment and career indecision. Participants are 401 unemployed people in their 20s who have never had a job. The major findings of this study are as follows. First, correlation analysis indicates that both anxious attachment and avoidant attachment are positively related to fear of negative evaluation and self-criticism. Also, anxious attachment is positively correlated with social comparison, whereas avoidant attachment is negatively correlated with it. Second, both insecure attachments have significant positive correlation with career indecision. Third, it shows the respective unique mechanisms by which each of the two insecure attachment forms are related to career indecision are distinctive: Specifically, The linkage between anxious attachment and career indecision is partially mediated by self-criticism and social comparison, whereas avoidant attachment is indirectly related to career indecision through a full mediation of self-criticism and social comparison. Implications and limitations of this study are discussed.

It has been known that it shows the negative correlation between social comparison and happiness. Nevertheless, the correlation depends on self-concept and motivation of comparison which a person take. Current study examined the effect of cultural self-concept (interdependent self, subjective-objective self) on social comparison and happiness (subjective well-being and psychological well-being), Total 2000 among 30-69 years old respondents participated in this survey. We found that, first, people with high interdependent self feel less happiness as they take more social comparison, but the people with low interdependent self do not show the relational pattern. Second, people with objective self show the negative correlation with happiness and social comparison, but there is no correlation with happiness and social comparison among people with subjective self. The implication for study were discussed.
