  • In order to deal with the classification problems of type-2 fuzzy training samples on generalized credibility space. Firstly the type-2 fuzzy training samples are reduced to ordinary fuzzy samples by the mean reduction method. Secondly the definition of strong fuzzy linear separable data for type-2 fuzzy samples on generalized credibility space is introduced. Further, by utilizing fuzzy chance-constrained programming and classic support vector machine, a support vector machine based on type-2 fuzzy training samples and established on generalized credibility space is given. An example shows the efficiency of the support vector machine.

  • 영화 흥행에 영향을 미치는 온라인 구전의 양과 방향성에 관한 선행연구들의 거의 대부분은 Yahoo Movies, IMDB.com, 네이버 영화 등에서 제공하는 실제 온라인 데이터(2차 데이터)를 사용하였다. 그러나 실제 온라인 데이터는 구전 제공자와 구전 수용자의 심리 변수나 특성 정보를 파악하기가 어렵기 때문에 실제 데이터를 사용한 선행연구들에서는 구전의 양 및 방향성과 소비자의 심리 변수 간의 인과관계를 파악할 수가 없었다. 본 연구에서는 선행연구의 이러한 한계를 보완하여 실제 데이터 대신에 설문조사를 통해 기존에 검증되지 않은 인과관계모형으로서 구전의 양과 방향성이 소비자 심리 변수이며 대표적인 구전 정보 특성인 리뷰 신뢰성을 매개변수로 하여 영화 관람의도에 미치는 직·간접적인 영향력을 검증하였다. 연구결과, 구전의 양과 방향성이 관람의도에 미치는 총효과는 각각 유의하였다. 그러나 구전의 양은 리뷰 신뢰성을 통해 관람의도에 미치는 간접적인 효과만이 유의한 반면에(완전매개효과), 방향성은 직접효과와 간접효과가 모두 유의한(부분매개효과) 차이가 나타났다. 이러한 연구결과에 대한 이론적, 실무적 시사점을 제시하였다.

  • A blog has significant effect as a new online medium and as a tool to share information with its powerful networking function. Blogs are established based on personal experience and their impact is stronger than conventional media in terms of informativeness, credibility and interactivity. Such characteristics of blogs lead to blog commitment (a phenomenon that has behavioral consequences) that eventually influences consumer fashion purchase behavior. The more a consumer is interested in fashion and seeks diverse information from a wide range of media, the more personally committed they become to certain blogs; in addition, they will also post the results of their fashion product purchases on their blog to further create and reproduce information. This research discovers how blog commitment affects fashion product purchase behavior and information reproduction activity among consumers as well as explores the impact of blog characteristics and information variety seeking by individual consumers on these factors. The data was collected from 428 adults who purchased a fashion product based on information they found on a blog. The results are as follows. First, blog characteristics are composed of accessibility, interactivity, credibility of the information, and informativeness. Second, in terms of the blog commitment, informativeness, credibility, and consumer information diversification (respectively), turned out to have positive effects; in addition, accessibility and credibility had positive effects for corporate blogs. The comparison between private and corporate blogs showed that consumers tend to be more committed to private blogs. Third, in terms of the brand attitude, private/corporate blog commitment, credibility, and consumer information diversification (respectively) had a positive influence. Fourth, blog characteristics and consumer information diversification led consumers (through private/corporate blog commitment) to form a favorable attitude towards the brand and purchase products that resulted in information reproduction of the purchased product.

  • This study aimed to provide information to establish a service strategy in cross-border e-commerce through an assessment of consumer satisfaction with a cross-border shopping channel and "amazon global store" managed by 11street, a domestic e-commerce corporation. The influence of brand familiarity with amazon as a global retail brand was tested. The mediating roles of the perceived value and risk of both cross-border shopping and amazon global store were investigated; the moderating role of the domestic e-commerce corporation was also studied. An empirical study was conducted on consumers who had experience using the amazon global store managed by 11street. To verify the hypothesis, data from 200 people was analyzed using PROCESS macro 4.0. The results indicated that familiarity with global brands did not have a direct effect on consumer satisfaction; the effect of global retail brand familiarity on consumer satisfaction was mediated only by the perceived value of cross-border shopping and amazon global store, not by the perceived risks. E-commerce corporate credibility showed a moderated mediation effect by mediating functional values of the amazon global store. For consumer groups with a credibility level of medium and above, the interaction effect of brand familiarity and corporate credibility was significant.

  • 본 연구는 회계투명성 결여로 인해 세계 최하위수준인 국가신인도 제고를 위한 회계실무교육제도 관련 정책제언에 그 목적이 있다. 국가신인도가 최하위인 이유 중 가장 큰 것은 감사인의 자유선임제도이고, 다음으로 회계에 대한 교육이 제대로 이루어지지 못하고 있다는 점이다. 본 연구는 우리나라 회계교육 개선방안에 대한 선행연구들과 각종 공청회, 보도자료, 정부의 정책자료 등을 정리한 서지학적 연구라 할 수 있다. 회계투명성을 높이는 길은 자유선임이라는 현행 감사제도의 개선과 회계실무교육을 제대로 담보해내는 것이다. 여기에서 감사제도는 2020년부터 주기적(6+3) 지정감사제도로 입법화되었기에, 문제는 회계실무교육으로 그 대상자가 민, 관 등 모든 영역에 속해 있기 때문에 정부차원의 회계전문교육기관인 (가칭)'회계연수원' 설립을 제안하고자 한다. 이를 통해 회계정보의 생산 이용하는 자들의 전문적인 실무교육훈련을 통해 회계투명성을 높이고 나아가 국가 신인도 제고에 기여할 것으로 예상된다.

  • The purpose of this study is to understand the impact of influencers on generation Z (Gen Z) in the online environment. This article has applied the theories of source credibility, TAM, IAM, and TPB to identify influencer characteristics that affect the purchasing behaviors of Gen Z customers. This research was conducted using a Google Form survey with 24 pre-designed questions. A total of 464 valid questionnaires from Gen Z Vietnamese were collected between November 2020 and January 2021. Data was analyzed using partial least squares structural equation modeling (PLS-SEM) with SmartPLS 3 software. The analysis results confirmed that the components of influencer credibility have a positive impact on Gen Z's purchasing behaviors under the mediated influence of argument quality, perceived usefulness, and social influence. Surprisingly, for Gen Z, the influencers' attractiveness has the strongest impact on their online behavior. More specifically, attractiveness plays the most important role in the perceived usefulness and social influence of Gen Z customers, while influencers' expertise has the strongest impact on argument quality delivered to customers. This study provides evidence of a change in the way Gen Z responds to marketing activities. They are more drawn by the attraction of influencers than their expertise.
