With the full spread and rapid development of social media, the trend of decentralization of social media information propagation is becoming clearer day by day, and the segmentation of time by audiences using social media information is clearly progressing. Therefore, this study aims to study the influence relationship between social media attitudes toward fake news, social capital, risk perception, and discriminant intentions based on existing studies. Accordingly, the research model presented related research questions and organized a questionnaire to collect a total of 500 valid surveys. The SPSS 26.0 program and the AMOS 24.0 program were used to analyze the data. The research results are as follows. First, the more positive the user's attitude towards the fake news identification intention of social media, the more they want to use various methods or tools to identify the authenticity of online information. Second, the more positive the user's attitude towards social media fake news, the more aware of the potential threats social media fake news poses to their own physical, psychological, financial and so on. At the same time, by raising one's own awareness of the dangers, counterintelligence intentions against fake news on social media will also increase. Third, the richer the social capital the user has, the stronger the information literacy, and therefore the stronger the identification intention of social media fake news. Fourth, the higher the value of social capital Chinese users have, the greater the damage they have suffered from fake news, and the higher the risk awareness of fake news to protect their interests. Fifth, it means that Chinese users recognized information suspected of social media and took corresponding measures.

Purpose: This study examines the weight control behavior depending on university students' motives of using social media. Methods: The participants were 447 university students in the Jeonbuk area. Collected data were analyzed using factor analysis, cluster analysis, analysis of variance, and χ² tests with SPSS v. 26.0. Considering the motives of using social media, we investigated the usage of social media, dietary behavior related to social media, and weight control behavior. Results: Using the K-clustering method, the motives to use social media were categorized into three clusters: cluster 1 was the interest-centered group, cluster 2 was the multipurpose information-seeking group, and cluster 3 was the relationship-centered group. Among the various social media sites, YouTube (86.8%), Instagram (76.1%), and Facebook (61.1%) were the most visited by the subjects. The dietary behavior related to social media in cluster 2 was significantly higher than clusters 1 and 3 (p < 0.001). Clusters 1 and 2 showed a significantly higher dissatisfaction with one's weight (p < 0.05) and consequent interest in weight control than cluster 3 (p < 0.001). Cluster 2 used weight control-related information from social media significantly more than other clusters (p < 0.05). Weight control experiences in cluster 1 and 2 were significantly higher than in cluster 3 (p < 0.001). Conclusion: Differences in dietary behavior related to social media and weight control behavior were observed between cluster types of motivation to use social media. Based on the usage motives of university students and their behaviors, we propose that educational programs should be conducted for weight control using social media.

As many people all over the world increasingly take more time in exchanging with other people or acquiring information on the internet, use of social media becomes a part of their daily lives. A lot of changes of consumer culture, which have been occurring through social media, have significant effects on corporate marketing activities. Since social media's importance to airlines has been continuously increased, this study attempts to examine effects of passengers' uses of social media, who plan to select an airline, on dependence on reliance of electronic word-of mouth(EWOM) and EWOM acceptance. To this end, a questionnaire survey of passengers who use airlines and the airline's social media was conducted, and then effective data of 302 copies were analyzed by using the structural equation modeling. The findings show that social media use intensity has a significant effect on Acceptance of EWOM via reliance of EWOM, while a direct effect of social media use intensity on Acceptance of EWOM is not significant. From this study, it is found that control and management of social media and only EWOM are effective tools for marketing of airline businesses, suggesting that innovative strategies are required to preemptively cope with changes in consumers' behaviors and markets, which continue to evolve.

Many users actively create and share digital contents in a variety of social media platforms. Social media users have become accustomed to posting or uploading their daily routines, and generating their contents by imitating others' contents or by creating their own unique contents on the basis of their creativity. Thus, this paper explores the relationship between individual creativity, imitation and creative behavior in using social media. In addition, the study demonstrates the moderating effect of individual characteristics such as age and educational level on the relationship between creativity and imitation. We conducted a three-month survey of 564 individuals using social media services and the results were used for hypotheses testing. The study results are summarized as follows. Firstly, creativity has a significant and positive impact on imitation, but not a direct impact on creative behavior. Secondly, the moderating effect of individual characteristics between creativity and imitation is not statistically significant. Based on these findings, this study presents practical and academic implications of the research.

In recent years, with the continuous integrative development of e-commerce and social media, social commerce, as a trust-centered social transaction mode, has become an important performance form of e-commerce. The good experience of online community and abundant user-generated content (UGC) attract more and more users and businesses to participate in the community contribution. In this context, the cost of accessing information is continuously decreasing, which not only makes the purchase process more concise and efficient, but also greatly increases the possibility of consumers' impulsive consumption. However, there are very few empirical studies on the internal influencing mechanism of consumers' impulsive consumption based on the characteristics of UGC for social commerce. In view of this, based on S-O-R model, this study constructs a model of consumers' impulsive consumption in the context of social commerce from the characteristics of UGC, with perceived risk as the mediating variable and tie strength as the moderating variable. The results show that content authenticity, content usefulness, and content valence of UGC have significant negative impacts on consumers' risk perception in the process of purchase decision-making, and consumers' perceived risk has a significant negative impact on consumers' impulsive consumption. Meanwhile, the tie strength between UGC producer and UGC receiver plays a moderating role between content usefulness and perceived risk, as well as between perceived risk and impulsive consumption. Finally, combined with the above findings, this study provides effective suggestions for relevant participants in social commerce in terms of business management.

This study examined the associations among self-disclosure tendency, self-activities and friends' responses on Facebook, and perceived usefulness of Facebook in social networking. Sex differences were also examined. Results showed that participants' self-disclosure tendency was positively related to their activities in Facebook, which were strongly related to friends-activities. Self- and friends-activities significantly increased usefulness in social networking. Regarding sex differences, the relationships between self-disclosure tendency and self-activities and between self-activities and usefulness were stronger for men, while the relationship between friends-activities and usefulness was stronger for women. These results suggest women tend to value friends' responses more in assessing relational qualities than men in Facebook contexts.

As the frequency and intensity of catastrophic disasters increase, there is widespread public sentiment that government capacity for disaster response and recovery is fundamentally limited, and that the involvement of civil society and the private sector is ever more vital. That is, in order to strengthen national disaster response capacity, governments need to build disaster systems that are more participatory and function through the channels of civil society, rather than continuing themselves to bear sole responsibility for these "wicked problems." With the advancement of smart mobile technology and social media, government and society as a whole have been called upon to apply these new information and communication technologies to address the current shortcomings of government-led disaster management. As illustrated in such catastrophic disasters as the 2011 Tohoku earthquake and tsunami in Japan, the 2010 Haitian earthquake, and Hurricane Katrina in the United States in 2005, the realization of participatory potential of smart technologies for better disaster response has enabled citizen participation via new smart technologies during disasters and resulted in positive impact on the management of such disasters. In this context, this study focuses on the South Korean context, and aims to analyze Korean government officials' readiness for public participation using smart technologies. On this basis, it aims to offer policy suggestions aimed at promoting smart technology-enabled citizen participation. For this purpose, it proposes a particular model, termed SMART (System, Motivation, Ability, Response, and Technology).
