This study is to verify the effect of similarity of expanded-product, brand concepts of parent-brands and implicit theory of customers on the brand-extension evaluation, in order to reduce the risk of brand extension. First, this research documents how the similarity between the parent-brands and expanded-products affect brand-extension evaluations as a main effect variable. Second, this study examines the moderating effect of the brand concepts of parent-brands on the brand-extension evaluation. Third, this research documents how implicit theories regarding personality affect consumer evaluations about the brand-extension. The study assumes and tests that consumers in the group of incremental theorists are more accepting of brand-extensions than consumers in the group of entity theorists. The result figures out the implicit theory customers has some moderating effect on the evaluations, yet the direction of the effects is contrary to expectations.

In the study, we endeavored to assess the convergence effect of Silybum marianum-derived silymarin and epidemiologically-correlated alcohol intake on vascular contractility and to determine the mechanism involved. There were few reports addressing the question whether thin or thick filament modulation is included in ethanol and silymarin-induced regulation. We hypothesized that ethanol at a low concentration and silymarin play a role in agonist-dependent regulation of vascular contractility. Denuded arterial muscles of Sprague-Dawley male rats were suspended in organ baths and isometric tensions were transduced and recorded using isometric transducers and an automatic data acquisition system. Interestingly, both silymarin and ethanol didn't encourage silymarin alone-induced inhibition in agonists-induced contraction suggesting that endothelial nitric oxide synthesis might be involved in ethanol or silymarin-induced modulation of vascular contractility and additional pathways besides endothelial nitric oxide synthesis such as ROCK inactivation might be involved in the silymarin-induced modulation of vascular contractility.

The present study identified the determinants of the behavioral intention to purchase an air purifier. This work further examined the moderating effect of interactivity readiness on the relation between the purchase intention and the word-of-mouth (WOM) intention. Our conceptual model included a second-order construct of SNS WOM richness, consisting of three first-order constucts of SNS WOM relevancy, timeliness and sufficiency. Furthermore, SNS WOM usefulness and credibility were incorporated into the model to predict the purchase intention. A total of 312 respondents participated in the survey study. A series of scale refinement processes were performed and a structural equation model analysis was conducted to verify our research hypotheses. The results indicated that SNS WOM richness was found to be significantly predictive of both SNS WOM usefulness and credibility, which in turn, had significant impacts on purchase intention. In addition, results revealed that purchase intention had a significant and positive influence on WOM intention. However, results failed to verify the moderating effect of interactivity readiness on the influence of behavioral intention on WOM intention.

Increased attention has worldwide been given to exporting SMEs pursuing the rapid internationalization from their inception. In spite of the limited resources, exporting SMEs have entered in global markets successfully and then improve their internationalization performance. Nevertheless, there is little empirical research regarding internationalization in exporting SMEs, Using a survey of 317 exporting SMEs, this study designated organizational, entrepreneurial, environmental, and technological characteristics as determinants of internationalization performance as well as investigates empirically the relationships among the determinants of internationalization performance, export Support programs of the government, and internationalization performance. According to the results of the study, firstly, R&D capacity, globalization-orientation, international market environment, and technological characteristics (e.g. technological capacity and imitation) have significant effects on international performances. Finally, it is found that export support programs moderated the relationships between market information management, R&D capacity, management capacity, international market information, and technological capacity, and internationalization performance. Above results indicate that if exporting SMEs would not use export support programs effectively, they could not improve internationalization performance. As well, several implications for researchers and practitioners, limitation of this study and future direction were suggested.

This study looks into the usage pattern in online games based on genres and socio-demographic characteristics. Compared to the prior studies that adopted survey as their main research method, this study has analyzed the actual data of game login records and adopted parametric modeling and mathematical approach. In terms of the socio-demographic characteristics, the following facts were confirmed: men > women by gender, students > white-collars > housewives > blue-collars > self-employed > jobless(etc.) by occupation, college graduates > K-12 students > high-school graduates > undergrads & grads by academic background, 3∼5 million > 1∼3 million > over 5 million > less than 1 million by income levels, and not married > married by marital status. In terms of genres, the population of the players is in the order of web board games, RPG, action/racing/shooting, and sports. The RPG game is confirmed to have a higher level of MCR (Max Concurrent User Ratio) than any other genres. On the other hand, the hypothesis on the difference in Repeated Use Ratio according to genres is rejected. This study has also confirmed that interactions exist between gender and age; genre and gender; genre and age among online game users, and conducted post-hoc analysis about those interactions.

COVID-19 has radically changed the behavior of members of society for exchange. In particular, the strong contagiousness of the virus is increasing networking on online platforms while reducing people's networking in the real world. Recently, the metaverse, which strengthened the presence based on 3D technology, is attracting attention from members of society such as individuals and companies. We present a method to improve metaverse utilization from the perspective of organizations and employees who have introduced metaverse for work. In other words, we check the effect of metaverse social function and telepresence on the employee's intention to offer support by improving the trust of the metaverse participants. We obtained samples through questionnaires targeting employees of organizations that introduced metaverse to their work, and verified the research hypothesis by applying the structural equation model. As a result, social interactivity, reciprocal favor, and telepresence of metaverse partially affected metaverse trust (platform, peer, organization), and metaverse trust increased the intention to offer support. Our study suggests a strategic direction to improve the metaverse utilization and exchange level of employees of organizations who want to use the metaverse for business.

The purpose of this paper is to provide values and effectiveness to libraries making a new social network service marketing model and strategy. According to study, when libraries entice library users with social network services, the users become loyal customers who give libraries long-term supports. For method of study, it establishes 15 hypotheses and proves those hypotheses with 157 responders. After inspecting hypotheses, 13 hypotheses are adopted and 3 hypotheses are dismissed. During the research, it is verified that usefulness perceived by library users is the most important factor of user satisfaction and continuous use intention which increased library users' intention to continue visiting the library. In addition, effectivness of marketing and cause are found in order of system quality, information quality, reliability, interactivity, subjective norms. In other words, the study found that library users found their information for using social network services and this attribute affects user satisfaction and ultimately continuous use intention in a positive way.

The results of advanced studies which handled the relationship between social norm and intention to use illegal download don't match exactly. This study determined that the reason why the results of advanced studies are confused is, that moderator variables play important roles. For this reason, this study planned to test for significance of moderators consisting of attitude to copyright law(A) and perceived price importance at time of purchase(B). To achieve this, the present study divide social norm into two norms(subjective norm and group norm) and set up hypotheses on the moderating effects of two variables(A, B) between these two norms and intention to use the illegal download. The results show that all but one hypotheses are accepted. The other moderating effect hypothesis which is consist of subjective norm and attitude toward copyright law is rejected. This means that the effect of group norm on intention to use illegal download is moderated by attitude to copyright law. Also, this result means the effects of group/subjective norm on intention to use illegal download is moderated by the perceived price importance at time of purchase.
