This study examined the effect of waiting in a service queue on the evaluation of service quality focused on its overall process, mediators and moderators The conceptual model of this paper integrates key variables derived from previous studies of consumer waiting behavior. Data obtained from actual customers in service queue at a hospital was used to test the theoretical framework. First, results from the path analysis confirm that negative affect and acceptability of the wait function as mediators in the process that the perceived duration of the wait affects customer's evaluation of overall service quality. Second, the analysis of the data, with the use of moderate regression shows that disconfirmation of wait time expectations, transaction importance, stability of wait time and wait environment work as moderate variables for the relationship between perceived duration of wait and negative affect. For the relationship between perceived wait time and acceptability of the wait, on the other hand, only transaction import ante shows a significant effect as a moderator.

The purpose of this study is to explore the determinants of actual demand for wireless broadband (WiBro) services in Korea. To this end, this study identifies conceptual definitions of diverse latent variables and determines the significance of the causal relationship between independent and dependent variables. It then presents the nomadic user concept by testing the moderator effect. This study also proposes a revised Unified Theory of Acceptance and Use of Technology (UTAUT) model, which is an appropriate model for wireless communication services and users' attributes. Prior research has concentrated exclusively on the Technology Acceptance Model (TAM) based on future potential users. Compared to previous studies, the current research model and analysis results are useful in not only academic but also industry contexts.

The study is to identify the factors influencing Chinese consumers' intentions to purchase organic food based on Theory of Planned Behavior (TPB) model. This research concentrates on the moderating effect of gender during the process. An offline investigation was used for the research purpose. Data for the study was gathered from February to March 2018. The total of 260 valid responses was used for this analysis. An online questionnaire was distributed through Email to Chinese consumers living in major cities of China and abroad to collect the data. Multi group analysis and model comparison were conducted to examine the moderating effect of gender. Our results support previous researches suggesting that gender moderates the relationship between attitude and behavioral intention. However, surprisingly, no significant moderating effect of gender on the relationship between subjective norms and behavioral intention was found. This paper revisited TPB antecedents and the moderating effect of gender focusing on Chinese organic food markets. The findings provide essential managerial implications to the marketers in this industry. Further research could examine whether TPB model can be applied to other potential purchasing groups.

This study examines the effects of SNS fashion influencer's authenticity on the followers' relationship maintenance intention and product purchase intention through the mediating role of fanship. In addition, influencer's attractiveness is proposed as a moderator affecting the authenticity on fanship; in addition, authenticity is operationalized as honesty and expertise. A written survey is developed for 181 female Instagram users. The analyses of the data yields the following findings. First, honesty has a positive effect on fanship, relationship maintenance intention and purchase intention, while expertise affects fanship and relationship maintenance intention, but does not have a significant effect on purchase intention. Second, honesty and expertise have a positive effect on follower behavior intention through the partial mediation of fanship. Third, social attractiveness and physical attractiveness have a significant effect on fanship. However, all interaction effects between authenticity and attractiveness are not significant. Unlike authenticity, attractiveness has no direct effect on follower behavior intention. This study verifies the critical role of authenticity for an influencer in the context of SNS marketing and commerce, as this factor leads to followers behavioral intention as well as fanship in both direct and mediated paths.

This study examined the effect of regulatory focus on adaptative performance for pilots and co-pilots engaged in domestic civil airlines, and verified the moderating effect of organizational commitment in the process of regulatory focus on adaptative performance. For study, the scale developed by Lockwood Penelope and others validated and developed to measure the regulatory focus was adapted to suit the aviation scene and examined through this. As a result of the study, among the sub-variables of the regulatory focus scale, the promotion focus had a statistically significant and positive effect on the adaptative performance. and derived that the prevention focus had a statistically significant negative effect on the adaptative performance. In order to examine the moderating effect of organizational commitment in the relationship between regulatory focus and adaptative performance, the results of hierarchical regression analysis were conducted after controlling the rank, background, and career. Organizational commitment showed a statistically significant positive moderating effect in the relationship of adaptative performance. In addition, as a result of the verification according to the level of organizational commitment, prevention focus and adaptative performance showed statistically significant negative effects when organizational commitment was high.

This research is on the relationship among organizational communication and organizational citizenship behavior focused on the moderating effect of transformational leadership. The objective of this research is to conduct positive verification of organizational communication impacting on organizational citizenship behavior. Also, to perform positive verification on moderating effect of transformational leadership. The variables are downward communication, upward communication, unofficial communication, organizational citizenship behavior including participatory actions, altruistic behavior, mindful behaviors, and transformational leadership. It was verified on survey of 232 peoples. The verification and analysis results will be provided to impact of organizational communication on organizational citizenship behavior, the downward communication impacts all elements of citizens' behaviors, and upward communication impacts of participatory actions. On the other hand, the unofficial communication did not impact at all. Moreover the results of moderating effect of transformational leadership. The transformational leadership act as moderator in downward, upward communications. but did not act as a moderator on the unofficial communication. The research suggests to use transformational leaderships to commanders and leaderships at military organizations to put efforts on active communication in order to manage unit more effectively and efficiently and to make members of organization to voluntarily. It is assessed that this paper will serve as a reference to whoever in military reform group or organization working for military developments working for creating elite forces.

This study aimed to identify the effects of death education programs among Korean aged on death anxiety and attitudes toward death in the convergence era. The searched kew words were included aged, death education program, death anxiety, and attitudes to death in the research papers published in Korea. Finally, 11 studies were selected and the effect size was calculated. Death anxiety and death attitude were selected as dependent variables, and publication type, total duration of intervention, and frequency of intervention were selected as moderator variables. The total of 11 papers were selected to estimate the effect sizes of interventions. As a result, the overall effect size of the death education program for the aged was 1.07. The overall effect size showed death education program was able to lower death anxiety (Hedges' g=1.30, 95% Cl=0.80~1.80, p<.01) and improve attitudes to death (Hedges' g=0.93, 95% Cl=0.49~1.37, p<.01) compared with the no intervention group. In the moderator analysis to identify the cause of heterogeneity, significant results were found in the frequency of intervention. We propose a study that repeatedly verifies the effect of related studies in the future by providing the theoretical basis and basic data for the development of the death education program.

This study empirically investigates the effect of self presentation on SNS to interpersonal relation and quality of life. Especially, we performed exploratory analysis that how SNS affect to quality of life and wether the change of interpersonal relation is mediating effect to quality of life and intention to use. And we also suggest that the capability of communication would be a moderator. In the results, firstly, the using SNS has significantly positive effect on the change of interpersonal relation. And it as mediation variable can positive impact on the relationship between the using SNS, quality of life, and Intention to use. In the moderating analysis, SNS users who responded higher communication capability have significantly more higher effect on the change of interpersonal relation and quality of life. Secondly, the change of interpersonal relation after use of SNS as a mediation variable serves to enhance the relationship between the use of SNS and the quality of life in the positive direction.
