Social networking service(SNS) helps users manage, share and delivery a vast information as a communication tool. When users read crisis news in SNS, they communicate the information with others by considering not only their belief (i.e., cognitive risk perception) but also emotion (i.e., affective risk perception). However, few researches have been interested in the construct of communication behaviors of crisis in SNS. This study aimed to explore the role of risk perception (cognitive and affective risk perception) between crisis responsibility and communication behavior through dual processing theory. As a result of the empirical analysis, crisis responsibility had a positive effect on cognitive risk perception and affective risk perception. In addition, cognitive risk perception had no significant effect on communication behavior whereas affective risk perception had influence on communication behavior positively. Thus, our findings may predict that the affective risk perception through crisis responsibility is more potentially important to communication behavior such as sharing information rather than cognitive risk perception. The results give insightful ideas why marketer should reduce perceived emotion caused by risk to strengthen prospective SNS users understanding of communication behavior intention.

Purpose - This study is intended to look into the influences of restaurant consumers' e-WOM information communication on product perception risk, benefit and WOM effect. Research design, data, and Methodology - To achieve this, a survey was empirically carried out to 426 restaurant consumers. Results - The findings are as follows. First, the influence of e-WOM on product perception risk showed that WOM information sender characteristics, WOM information recipient characteristics and online community had a statistically significant positive influence on product perception risk. Second, the influence of e-WOM on product risk benefit showed that WOM information sender characteristics, WOM information recipient characteristics and online communication had a statistically significant positive influence on product risk benefit. Third, WOM risk perception had a statistically significant positive influence on WOM acceptance. Fourth, WOM risk benefit had a statistically significant positive influence on WOM effect. Conclusions - As for the above-mentioned findings, the communication between e-WOM sender and recipient had a positive influence on the product evaluation and attitude change in the restaurant industry, and the WOM effect had an influence on the financial performance and non-financial performance. The communication attaches importance to a direct using and tasting experience due to the nature of restaurant industry when it is simultaneously performed as a positive mechanism between sender and recipient through each channel of these factors. But the e-WOM culture can lead to the WOM effect when both sender and recipient share the persuasive communicability in reality that diversifies communication methods, having a positive influence on the management performance.

Purpose: This study aims to identify the relationship between nursing students' social anxiety and communication ability, and in particular, to determine the mediating effect of self-efficacy. Methods: A total of 187 nursing students enrolled at four universities in Korea completed surveys between August and September 2020. The measurements included the Global Interpersonal Communication Competence Scale, self-efficacy scales, and interaction anxiousness scales. Data were analyzed using descriptive statistics, an independent t-test, one-way ANOVA, Pearson's correlation, multiple regression following the Baron and Kenny method, and bootstrapping for mediation. Results: Communication ability was significantly negatively correlated with social anxiety (r=-.61, p<.001) and significantly positively correlated with self-efficacy (r=.77, p<.001). Furthermore, self-efficacy had a partial mediating effect on the relationship between social anxiety and communication ability. Conclusion: The findings of this study suggest that communication ability can be improved if individual characteristics such as social anxiety and self-efficacy are considered. Therefore, when developing communication ability improvement programs for nursing students in the future, it is considered important to actively consider these personal characteristics.
