During the last decade, social live streaming service like Periscope, Ustream, and YouNow has developed from a niche market into a mainstream activity. In this media environment, social live streaming service has a tremendous impact on the social behaviors of users. Despite the rapid development, there are a lack of studies to make better understand the media environment changes through social live streaming service. This study adopted an affordances approach that leads us to identify six distinctive social affordances (visibility, accessibility, information sharing, social interaction, role-taking, interactive revenue) for user engagement in social live streaming service. Specifically, this study explores the impact of social affordances on perceived flow, followed by user engagement including passive and active engagement. Empirical data analysis with 258 questionnaires suggests that social affordances affected users' flow perception, and flow has an effect on active as well as passive engagement. Contrary to the expectation in a hypothesized research model, only the impact of accessibility on flow was rejected.

This paper proposes the presence and importance of cultural differences to address user engagement in worldwide social media platforms. Based on Hofstede's cultural dimensions, this paper addresses their new meanings in the context of user engagement in social media. Our propositions address two research questions: (1) how do cultural dimensions, displayed on social media platforms, differ across national cultures?; (2) what different preferences the social media platforms have in terms of which cultural dimensions promote or suppress user engagement? User engagement in social media platforms is explained by the cultural differences in terms of the four cultural dimensions: individualism vs. collectivism, uncertainty avoidance, power distance, and masculinity vs. femininity. Implications are also discussed for research and practice.

The purpose of this study was to explore the moderating effect of food safety scandals on the relationship between food company's Corporate Social Responsibility(CSR) engagement at different levels and brand image in the Chinese dairy company context. In addition, this study also examined the mediating effect of brand image on CSR engagement and consumer loyalty. The study adopted a $2{\times}2$ between-subjects experimental design using scenarios. Four scenarios provided a mixed combination of yes or no cases for food safety scandal, and high or low cases for a dairy company's CSR engagement. In this study, survey was used to collect data from Chinese consumers. Of these, 377 valid data were collected from a sample of average Chinese consumers over the age of 20, collected through the internet. The results show that CSR engagement at different levels has a significant effect on brand image and food safety scandal has a significant moderating effect on the relationship between the two. This study expanded the previous study on the sensitivity of consumers to CSR activities in eastern China. At the same time, according to the results of the study, different CSR engagement of food enterprises does have a significant impact on brand image and consumer loyalty. In particular, high CSR engagement reduces negative impact on brand image through the moderating effect of food safety scandals. Therefore, for food business managers, actively participate in CSR activities, and actively enhance the engagement has a significant influence on the management of brand image.

본 연구는 정서사건이론을 기반으로 조직 상황에서 직무사건이 직무열의에 영향을 미치는 과정에서 개인차 변수인 조절초점이 어떠한 영향을 미치는지 살펴보는 것을 목적으로 하였다. 이를 위해 금융권 종사자 232명을 대상으로 긍정사건, 긍정정서, 조절초점 및 직무열의에 대한 설문조사를 실시하였다. 연구 결과는 다음과 같다. 첫째, 주효과 검증에서 금융업 종사자들이 경험하는 긍정사건은 긍정정서를 높여 직무열의에 정적인 영향력을 미치는 것으로 나타났다. 둘째, 조절효과 검증에서 긍정정서가 직무열의에 미치는 영향은 조절초점의 수준에 따라 차별적인 영향력을 보였다. 즉, 향상초점 수준이 높을수록 긍정정서의 직무열의에 대한 효과는 강화되었고, 예방초점 수준이 높을수록 긍정정서의 직무열의에 대한 효과는 약화되는 것으로 확인되었다. 셋째, 조절된 매개 효과 검증에서는 향상초점이 아닌 예방초점에서만 조건적 간접효과가 발견되었다. 즉, 긍정사건이 긍정정서를 매개로 하여 직무열의에 미치는 간접효과의 크기는 예방초점이 높을 때 약화되는 것으로 나타났다. 마지막으로 이러한 결과를 바탕으로 연구의 의의와 제한점 및 추후 연구 이슈에 대해서 논의하였다.

Purpose : The purpose of this study was two-fold: to identify the effect of dental hygienist's self-determination motivation on their job engagement and to analyze the moderating effect of compensation satisfaction that affect the relevance. Methods : Data were collected using a structured self-report questionnaire administered to 260 dental hygienists working in dental hospitals and clinics in Busan, South Korea. These were analyzed using IBM SPSS Statistics version 26.0 and SPSS Process Macro 3.5. A frequency analysis, including the respondents' general characteristics, frequency, percentages, and standard deviations, was performed. A regression analysis was also performed using SPSS Process Macro to verify the moderating effect of compensation satisfaction in the effect of self-determination motivation on job engagement. Results : The self-determination motivation of the dental hygienists had a statistically significant positive effect on their job engagement, which was the dependent variable. Higher intangible compensation satisfaction levels led to a stronger effect of intrinsic motivation but a weaker effect of extrinsic motivation on job engagement. Moreover, higher tangible compensation satisfaction levels strengthened the effect of intrinsic motivation on job engagement. Conclusion : Recently, the demand for oral health care has been increasing, Competition in the dental medical service market warrants, high-quality dental services based on accurate diagnosis and treatment. In this context, dental hygienists' job engagement must be improved. For this purpose, increasing the satisfaction of dental hygienists with self-determination motivation and appropriate compensation is effective. In addition, attention must be paid to the moderating effect of compensation satisfaction on the relationship between intrinsic motivation and job engagement. On the basis of the implications of this study, the results can be used as basic data for improving dental hygienists' welfare system and manpower management.

Purpose: The Purpose of this study was to examine school health teachers' burnout, engagement, job demands and job resources and to identify the factors that influence burnout and engagement. Methods: The participants were 222 school health teachers working in elementary, middle or high schools. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and hierarchical multiple regression. Results: The significant factors influencing burnout were rewards (${\beta}=-.51$), autonomy (${\beta}=-.15$), and job demands (${\beta}=.13$). These factors explained 42% of the variance in burnout. The significant factors influencing engagement were feedback (${\beta}=.49$), rewards (${\beta}=.21$), type of employment (${\beta}=.15$) and autonomy (${\beta}=.13$). These factors explained 49% of the variance in engagement. Conclusion: The study showed that job demands increase burnout, while job resources such as rewards and autonomy alleviate it. In addition, job resources, such as feedback, rewards and autonomy, increase engagement among school health teachers. Therefore, in order to reduce burnout and increase engagement among school health teachers, it is necessary to reduce the level of job demands and to provide enough job resources such as rewards, autonomy and feedback by improving the job environment.
