Purpose: Social Network Sites(SNS) have been grown up as a public communication channel consumer frequently participate in. Most of food service brands are utilizing social media for advertising recently. As a result of SNS marketing, food service brands anticipate positive outputs from SNS engagement and consumer brand engagement so that we need to verify structural relationship among SNS characteristics, SNS engagement and consumer brand engagement. Research design, data, and methodology: This study identifies that SNS characteristics have effects on SNS engagement and examines relationship between SNS engagement and behavioral engagement. We conceptualize SNS characteristics as information quality, hedonic level and interaction. Furthermore, SNS engagement is composed of SNS participation, positive word of mouth(WOM). In order to verify the purposes of this research, research model and hypotheses were developed. All constructs were measured with multiple items developed and tested in the previous studies. Sample data were collected from 433 online survey panels and analyzed by using SmartPLS 3.2.9. Result: The findings of this research are as follows. First, information quality is positively related with SNS participation. Hedonic level and interaction have impacts on SNS participation and positive WOM respectively. Second, SNS participation has positive effects on positive WOM. Third, both SNS participation and WOM influence behavioral engagement respectively. Conclusions: The implications demonstrate that SNS characteristics such as information quality and hedonic level and interaction exert effects for consumer to participate in SNS brand page. Meanwhile, hedonic level and interaction influence on positive WOM but information quality doesn't. SNS participation and positive WOM affect consumer to engage in specific brand behaviorally as well. Therefore, food service brand marketer is required to manage SNS information quality and hedonic level and interaction among members to encourage SNS participation and positive WOM. As SNS participation and positive WOM increases behavioral engagement of consumer, marketer needs to incentivize SNS participation and look after situation of positive WOM and respond swiftly.

This study aimed to investigates the effects of self-assertiveness and appearance satisfaction on psychological well-being (personal growth, purpose in life, self acceptance, environmental mastery, autonomy and interpersonal relations), and find out if there exists any causal relationship among each variable in the process. For data collection, a questionnaire was administrated from April 23 to May 13, 2012 in the city of Gwangju, Korea. The subjects were women in their twenties and thirties. 359 women responded to it. The results were as follows. First, overall self assertiveness had positive effects on appearance satisfaction which, in turn, turned out to have overall positive effects. Second, the overall effects of self assertiveness on psychological well-being turned out to have positive effects. Third, overall appearance satisfaction had positive effects on psychological well being. Forth, the effects that self assertiveness had on psychological well-being mediated appearance satisfaction and appeared to be partly insignificant. The implications and the direction of this research should be discussed in the future study so that it can improve personal psychological well-being by finding out other variables aside from self assertiveness, appearance satisfaction.

For a further understanding of the Chinese consumer, this study investigated 1) the effects of aesthetic consciousness on make-up attitude, and 2) the differences in the effect of aesthetics consciousness on make-up attitude among age groups. An online survey was conducted on female consumers belonging to the post-80s and 90s generations, living in Xian China. SPSS 24.0 and Amos 18.0 was used for data analysis. Confirmatory factor analysis for the research variables were performed and three factors of aesthetic consciousness (social relations consideration, internal consideration, and external consideration), and four factors of make-up attitude (psychological pleasure, self-satisfaction, consciousness of others, and tool of transformation) were identified. The results from the model test were : 1) aesthetics consciousness was found to vary depending on make-up attitude. Social relations consideration had a positive effects on psychological pleasure, self-satisfaction, and tool of transformation. Internal consideration had a positive effect on self-satisfaction and tool of transformation, and a negative effect on psychological pleasure. External consideration had positive effects on all four factors of make-up attitude. 2) In the post-80s participants, social relations consideration and external consideration had positive effects on all four factors of make-up attitude. Internal consideration s had a negative effect on consciousness of others and a positive effect on tool of transformation. In the post-90s participants, social relations consideration had positive effects on psychological pleasure, self-satisfaction, and tool of transformation. Internal consideration had positive effects on psychological pleasure and self-satisfaction.

Effects of the selective alpha-adrenoceptor agonists, clonidine, oxymetazoline and phenylephrine, on heart rate and contractile force were investigated in the isolated frog atria and it was attempted to examine the influence of adrenoceptor antagonist upon those. Clonidine produced dose-dependent negative chronotropic and positive inotropic effects. The negative chronotropic effect was significantly attenuated in the presence of prazosin and yohimbine but not propranolol. The positive inotropic effect was significantly attenuated by prazosin, yohimbine and propranolol. Oxymetazoline produced dose-dependent negative chronotropic and inotropic effects. The negative chronotropic effect was significantly attenuated in the presence of prazosin, which was partially augmented by yohimbine but was not affected by propranolol. The negative inotropic effect was not affected by propranolol but it was partially augmented by yohimbine and was partially attenuated by prazosin. Phenylephrine produced dose-dependent positive chronotropic and inotropic effects. The positive chronotropic and inotropic effect were significantly attenuated in the presence of propranolol but were not affected by prazosin and yohimbine. These results suggest that the negative chronotropic effect by clonidine and oxymetazoline is mediated by alpha-adrenoceptors, the positive chronotropic and inotropic effects by phenylephrine are mediated by beta-adrenoceptors, and alpha-adrenoceptors mediated the inhibitory chronotropic responses exists in the isolated frog atria.

Transformational and authentic leadership are known to create positive effects on follower's various outcomes, like job satisfaction and organizational commitment. We're mostly interested in testing positive effects of transformational and authentic leadership of cabin team leaders in airline industry, because their leadership tends to have strong and immediate impact on cabin crew's quality of customer services. We figured that cabin team leader's transformational and authentic leadership had positive effects on crew member's job satisfaction and organizational commitment. And, these positive relationships were at least partially mediated through crew member's self-efficacy and LMX. Based on these positive results, we discussed several theoretical and practical implications for developing effective leadership across cabin team leaders in airline services industry.

The Positive List System was newly introduced in South Korea as of January 2007. This study aims to survey and compare perception of and attitudes toward the Positive List System in the process of new drug listing that health professionals and pharmaceutical companies have. 50 professionals and 52 companies answered the questionnaire regarding health policy environments, policy decision/enforcement process, policy effects and satisfaction related to introducing the Positive List System. SAS 9.1 was used for statistical analyses. The results showed that participants had the general sympathy with health policy environments for the introduction of the Positive List System into South Korea. However, the response rates of policy decision/enforcement process and effects were negative and these tendencies were more striking in pharmaceutical companies. As for policy satisfaction, participants marked positive responses more than negative ones. It is necessary to remedy and supplement problems with policy decision/enforcement policy and effects revealed in this study and to improve the Positive List System through gathering opinions among groups and organization concerned.

Purpose - Current study aimed at investigating customer experience types (gain vs. loss avoidance performance experience and hedonic vs. reliability imagery experience) and their influences on satisfaction and positive emotion as antecedents of customer engagement. It also explored moderation role of regulatory focus in the influence of each experience type on satisfaction and positive emotion. Research design, data, and methodology - 416 Vietnamese local tourists were selected to test hypotheses by structural equation model in AMOS 21.0. Results - First, customers actually achieving gain or avoiding loss are more satisfied. Second, customers with hedonic and reliability imagery experience feel more positive emotion. Third, both positive emotion and satisfaction have positive influences on customer engagement. Last, regulatory focus moderates the positive effects of either gain or loss avoidance performance experience on satisfaction and also moderates the positive effects of either hedonic or reliability imagery experience on positive emotion. Conclusions - Focusing on both cognitive satisfaction and affective emotion resulted from experience, this study could advance customer engagement theory. Managerially, brand managers should induce gain performance and hedonic imagery experience (loss avoidance performance and reliability imagery experience) from promotion (prevention)-focused customers to enhance their engagement.

Marginalized random effects models (MREM) are commonly used to analyze longitudinal categorical data when the population-averaged effects is of interest. In these models, random effects are used to explain both subject and time variations. The estimation of the random effects covariance matrix is not simple in MREM because of the high dimension and the positive definiteness. A relatively simple structure for the correlation is assumed such as a homogeneous AR(1) structure; however, it is too strong of an assumption. In consequence, the estimates of the fixed effects can be biased. To avoid this problem, we introduce one approach to explain a heterogenous random effects covariance matrix using a modified Cholesky decomposition. The approach results in parameters that can be easily modeled without concern that the resulting estimator will not be positive definite. The interpretation of the parameters is sensible. We analyze metabolic syndrome data from a Korean Genomic Epidemiology Study using this method.

Generalized linear mixed models(GLMMs) are frequently used for the analysis of longitudinal categorical data when the subject-specific effects is of interest. In GLMMs, the structure of the random effects covariance matrix is important for the estimation of fixed effects and to explain subject and time variations. The estimation of the matrix is not simple because of the high dimension and the positive definiteness; subsequently, we practically use the simple structure of the covariance matrix such as AR(1). However, this strong assumption can result in biased estimates of the fixed effects. In this paper, we introduce Bayesian modeling approaches for the random effects covariance matrix using a modified Cholesky decomposition. The modified Cholesky decomposition approach has been used to explain a heterogenous random effects covariance matrix and the subsequent estimated covariance matrix will be positive definite. We analyze metabolic syndrome data from a Korean Genomic Epidemiology Study using these methods.

Purpose In the era of the 4th industrial revolution, the introduction of unmanned stores is rapidly spreading throughout the entire distribution market. Unmanned stores are stores where consumers purchase products on their own through machines and not through contact with people. As there are no managers in unmanned stores, Servicescape is expected to have many effects on the purchasing behavior of consumers. Therefore, this study aims to observe the effect of Servicescape on consumer behavioral intentions. Design/methodology/approach This study wanted to look at the relationships among Servicescape in unmanned stores, utilitarian values, hedonic values, satisfaction, and continuous use intentions. The collected(n=211) from individuals who have experienced in using unmanned stores was analyzed with SmartPLS2.0 to test proposed hypotheses. Findings The research results are as follows. First, it was shown that the space, convenience, and comfortableness of Servicescape have positive effects on utilitarian value, and cleanliness did not have significant effects on utilitarian value. Second, it was shown that space and comfortableness had positive effects on hedonic value, and convenience and cleanliness did not have significant effects on hedonic value. Lastly, it was shown that utilitarian values and hedonic values have positive effects on satisfaction, and satisfaction was found to have positive effects on continuous use intentions.
