This study was to explore purchasing behavior and repurchase intention by considering social-face sensitivity and conspicuous consumption. To do this, first, this study tried to explain how consumers had different characteristics for social-face sensitivity, conspicuous consumption, purchasing behavior, and repurchase intention for outdoor wear. Second, this study tested the relationship between consumer behavior (purchasing behavior and repurchase intention) and social-face sensitivity by considering the mediating effect of conspicuous consumption. As the results, first, there was a significant relationship between social-face sensitivity (sensitivity to saving face) and conspicuous consumption, which had a significant effect on the purchasing behavior with outdoor wear(purchase frequency, purchase cost). Second, social-face sensitivity (consciousness of shame) had a significant effect on conspicuous consumption (preference for famous brands, status symbol, pursuing fashion), and social face sensitivity (consciousness of social formality) had a significant effect on conspicuous consumption (preference for famous brands). The relationship between the conspicuous consumption and purchasing behavior showed that conspicuous consumption had significant effects on consumer behavior (purchase frequency, purchase cost). The relationship between the social-face sensitivity and purchasing behavior showed that being conscious of others had a significant effect on purchasing behavior. Third, purchasing behavior with outdoor wear had a significant effect on repurchase intention. Finally, this study confirmed that conspicuous consumption had a partially significant mediating effect on the relationship between social-face sensitivity (sensitivity to saving face) and purchasing behavior.

Commercial buildings account for significant portions of the total building energy in Korea, and thus, a variety of research on chiller operation has been carried out. However, most of the studies were carried out on the chiller itself, i.e., the part load ratio characteristics and the corresponding electricity energy consumption patterns were not analyzed in existing studies. In this study, the part load ratio and the operating characteristics of the vapor compression chiller were analyzed within an office building equipped with the conventional variable air volume system. As a result, significant portions of total operating hours, cooling load, and energy consumption turned out to be in the part load ratio range of 0 through 50%. Thus, energy consumption was significantly affected by the chiller COP at low part load conditions, indicating that chiller operation at the part load is an important factor in commercial buildings.

This study aims to subdivide consumers by attributes determined mainly by consumers of fresh ginseng. It is to compare and analyze the characteristics by cluster, and to deduce the implications on distribution and marketing. For this study, a survey was conducted targeting 250 consumers of fresh ginseng. The factors were deduced through performing the exploratory factor analysis on the results of the survey, and the consumers of fresh ginseng were classified through cluster analysis. As a result of the study, the attributes considered for the purchase of fresh ginseng were condensed to the three factors: physical characteristic factor, safety factor, and cultivation indication information factor. With these as the standard, the consumers of fresh ginseng were subdivided into the three clusters: safety-oriented consumption type, label-centered consumption type, and high involvement consumption type. It was found that there were differences in demographic characteristics and attributes considered for purchase of fresh ginseng by cluster analysis. This study suggests the implications for revitalization of the fresh ginseng industry by subdividing consumers of fresh ginseng and suggesting the characteristics by cluster.

This study examines the effect of live commerce characteristics on consumption behavior mediated by presence. As contactless shopping has become the new normal, live commerce is emerging as an innovative communication service between consumers and sellers. We examine the role of interaction and streamers' attributes on sharing and purchase intention by mediating social presence and telepresence. A web-based experiment was conducted to test our hypotheses. The data of 267 participants were analyzed using SPSS 23.0 and AMOS 21.0. The results showed that the Streamer-Consumer interaction had a positive effect on social presence and telepresence. By contrast, the Consumer-Consumer interaction had no significant effect on social presence and telepresence. We further found that streamer trustworthiness had a positive effect on both social presence and telepresence, while streamer attractiveness had a positive effect only on telepresence. Thus, social presence and telepresence positively influenced sharing and purchase intention. Overall, these findings illustrate that the Streamer-Consumer interaction and streamer trustworthiness are vital characteristics that lead to higher levels of presence using live commerce. Several academic and managerial implications are suggested based on these results.

Objectives : To prevent stroke, it is very important to reduce risk factors which might cause stroke. However, previous studies that having investigated coffee consumption associated with stroke reported various results. In addition, there were only a few studies based on the Korean population. Therefore, we studied the association of coffee consumption and the possibility of getting stroke among Koreans. Methods : A case-control study was carried out on 207 cases(stroke patients) and 207 controls(non-stroke patients) in a hospital. Information on characteristics, health habits, dietary habits and coffee consumption were obtained through direct interview by using an organized questionnaire; WHR(Waist-Hip Ratio) was determined through physical examination. The coffee consumption was classified by the average frequency of intake, such as less than 1 cup/day, 2-3 cups/day, more than 5 cups/day). Possible confounding effects of age, sex, smoking and alcohol drinking were controlled by multiple logistically regressive analysis. Results : After adjusting age and sex, coffee consumption significantly increased risk factors of stroke(${\leq}$1 cup/day OR=1.018, 95% CI=0.631-1.644; 2-3 cup/day OR=1.782, 95%CI=1.032-3.079;${\geq}$5 cup/day OR=1.210, 95% CI=0.588-2.490). When other factors were controlled, the risk factors of stroke were associated with alcohol drinking, whereas no significant association was observed with coffee consumption. Conclusion : Coffee consumption is not a major risk factor of causing stroke in this study. Prospective and cohort study on the association between coffee consumption and the possibility of getting strokes among the Korean population will be needed in the future.

The millennial generation, which has emerged as one of the strongest influence and consumption power, pursues happiness of the present centering on "I"; consumes luxury products for themselves. The purpose of this study was to evaluate how the narcissism and materialism of the millennial generation affect the compensatory consumption of luxury products in negative situations and the moderating effect of self-control. This study included 315 millennial males and females living in Seoul and Gyeonggi area. Frequency analysis, reliability analysis, multiple regression analysis, and hierarchical regression analysis were conducted using SPSS 25.0 statistical program. Based on our findings, narcissism and materialism had a statistically significant effect on compensatory consumption under positive situations. However, while materialism had a statistically significant effect on compensatory consumption under negative situations, narcissism did not have a statistically significant effect on compensatory consumption under negative situations. Notably, self-control had a moderating effect in the influence of materialism on compensatory consumption under negative situations; narcissism did not. This study holds academic significance as the concept of compensatory consumption and self-control can be applied to the apparel study. Moreover, this study provides practically significant ideas on compensatory consumption and therefore marketing of luxury brands, based on consumers' characteristics.

최근 몇 년 동안 전자상거래와 소셜미디어의 지속적인 통합 발전과 함께 소셜커머스는 신뢰 중심의 사회적 거래 방식으로서 전자상거래의 중요한 형태로 자리를 잡았다. 온라인 커뮤니티의 긍정적인 측면과 풍부한 사용자 제작 콘텐츠 (UGC)로 인해 커뮤니티에 참여하는 사용자와 기업이 점점 더 증가하고 있는 추세이다. 이러한 상황에서 정보접근 비용은 지속적으로 감소하고 있고 구매 프로세스는 보다 간결하고 효율적으로 개선되고 있는 반면에 소비자의 충동구매 가능성을 크게 높이는 결과를 가져오게 된다. 그럼에도 불구하고 아직까지 소셜커머스에서 UGC의 특성을 기반으로 한 소비자 충동구매의 메커니즘에 대한 실증적 연구는 거의 없다. 본 연구는 자극-유기체-반응 (S-O-R) 모델을 이용하여 소셜커머스에서 UGC 특성이 소비자 충동구매에 미치는 영향을 분석하는 연구모형을 구축하였고, 이 과정에서 지각된 위험을 매개변수로, 유대강도를 조절변수로 각각 설정하였다. 실증분석 결과 콘텐츠 진정성, 콘텐츠 유용성, 그리고 콘텐츠 가치는 구매의사결정 과정에서 소비자의 지각된 위험에 유의한 영향을 미치고, 소비자의 지각된 위험은 충동구매에 유의한 영향을 미치는 것으로 나타났다. 한편, UGC 생산자와 이용자 간의 유대강도는 콘텐츠 유용성과 지각된 위험의 관계 및 지각된 위험과 충동구매 관계를 조절하는 것으로 나타났다. 이러한 연구결과는 소셜커머스 사업자들로 하여금 고객의 소비행동에 대한 심층적인 이해를 도울 뿐만 아니라 소비자 충동구매가 왜 일어나는지에 대한 메커니즘을 학술적 관점에서 분석할 수 있는 이론적 틀을 제공하였다는 점에서 의의가 있다.
