  • 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.

  • In order to study a way of noise reduction in the conventional negative picking motion the authors suggested the spring-magnetic negative picking mechanism. The sound pressure level in the spring-magnetic negative picking mechanism can be expected to be 84.5 dB(A) by the comparison of noise sourses of the conventional and spring-magnetic negative picking mechanism. The operational behavior of the spring-magnetic negative picking mechanism was represented by the over-all operational block chagram.

  • 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.

  • 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 aim of the present study was to develop a cognitive-behavioral group therapy program for social anxiety in Korean adolescents and to examine its efficacy through pre-, post- and 2-year follow-up tests. The program included cognitive restructuring, exposure training and social skills training. KSAS-A and SASC-R were administered to 588 1st grade middle-school female students to assess their social anxiety levels. On the basis of double criteria procedure(top 10% scores on both scales), 59 students were selected initially. Individuals currently receiving clinical treatment were excluded. Finally, 40 students were selected and randomly assigned to either a treatment group or a wait-list control group. The program consisted of 12 weekly sessions, approximately 1.5-2 hours in duration. Whereas pre- and post-tests were administered to both groups, follow-up tests were administered to the treatment group only. The collected data were statistically analyzed through independent t-test and paired t-test. The results of the study were as follows: 1) At post-test students in the treatment group showed a very significant reduction in social anxiety and fear of negative evaluation by others in comparison with those in the wait-list group. 2) At post-test students in the treatment group showed a significant reduction in negative automatic thoughts in comparison with those in the wait-list group. 3) At post-test students in the treatment group showed a significant improvement in overall social skills in comparison with those in the wait-list group. 4) At post-test students in the wait-list group showed a significant increase in both social anxiety and negative automatic thoughts in comparison with those in the treatment group. 5) At 3-month, 1-year and 2-year follow-ups, the program's effectiveness was maintained.

  • This study aimed to identify specific psychological and brain activation responses relating to the processing of negative emotions in patients with alcohol dependency. The authors hypothesized that patients with alcohol dependency would demonstrate the abnormal functioning of brain regions involved in negative emotions. Eleven male patients diagnosed with alcohol dependence in an inpatient alcohol treatment facility and 13 social drinkers with similar demographics were scanned using functional magnetic resonance imaging (fMRI) as they viewed film clips that evoked negative emotions. During exposure to negative emotional stimuli, the control group evinced significantly greater activity in the right anterior cingulate cortex (ACC) in comparison to patients with alcohol dependency. Correlation analyses demonstrated a negative association in the relationship between beta values from the right ACC and amygdala in participants classified in the control group. No statistically significant relationship was observed for blood oxygenation level-dependent (BOLD) changes between the two regions in the patient group during the elicitation of negative emotions. On the other hand, patients exhibited a greater activation of the amygdala as negative emotions were induced. These results suggest that alcoholism presents pathophysiology of brain activation that is distinct from the responses of healthy individuals functioning as controls.

  • The purpose of this study was to compare Korean mothers' and fathers' reactions to their children's negative emotions. The survey with questionnaire was performed with 179 mothers and 179 fathers of children aged three to five-years-old from three child care centers in Seoul and Kyoungki Province. Parental emotion-related practices regarding children's negative emotions were assessed with an adaptation of the CCNES-R(Cortes, 2002), and parental reactions were categorized as problem-focused, emotion-focused, expressive encouragement, emotion-teaching, punitive, parental distress and minimizing. The main results were as follows. First, Korean mothers and fathers, in general, used more positive reactions than negative reactions when their children showed negative emotions, in particular problem-focused reactions were mostly used. In addition, Korean mothers were significantly higher than fathers on problem-focused and emotion-teaching reactions. Second, Korean mothers' and fathers' reactions to their children's negative emotions were significantly different depending on the educational level of mothers, mothers' job and fathers' job. But there was no significant differences in parent's reactions according to children's sex and age. The findings in this study provide implication for an association between parent's reactions to children's negative emotions and parent's socioeconomic background.
