In this study, out of the 530 beauty social commerce users, 244 people who had experience purchasing coupons for cosmetic surgery were surveyed to analyze the impact of the awareness of cosmetic surgery on satisfaction and on the purchase of new products. The reason why we did not purchase the coupon for cosmetic surgery was because we did not have enough information and did not trust the company and aong the factors used for cosmetic surgery, convenience, satisfaction, and repurchase are found to have a positive (+) effect (p<0.001) and We recognized convenience as an important factor. therefore, It is believed that social commerce companies and aesthetic medical agencies will need to improve their customer service, how to use the site, and provide objective information.

Because of rapid spread of the PC, many users have been enjoying a variety of content as PC. Especially in recent years, young people has increased dramatically PC usage. Young people get more easily information using a PC. Especially they relieve their stress through online games and feel another fun of virtual reality. It is obviously a good effect that they contact IT culture with rapidly developed. But young people's perspective with world is narrow because of doing more indoor activities than outdoor. Therefore we built Spot experience voucher system using smart phone application. We hope that many young people act outdoor activities. And Our product offer hybrid device by developing HTML5-based app. Thus this app will give interest of spot-experience to young-people. So If young people use this app, they can have many experience and see diverse aspects.

The renowned Pareto rule of 80/20 has been challenged in the electronic marketplace with the emergence of long tail economy. Mass customization on top of the Internet infrastructure is expected to explain these changes of product concentration. In this paper, we empirically analyzed the micro-transactional data of a Groupon-like daily deal web site to identify the changes of product and customer concentration. The results show the long tail pattern aligned with the previous research on the e-commerce literature on the long tail. We find that the notification setting on email or SMS about daily deal influences the patterns of sales concentration. The information through email and SMS is expected to enable consumers to know about daily bargains and purchase the coupons eventually. However, the email notification for niche products results in the decreased sales while the SMS notification for overall product promotes overall products.

The purpose of this study is to examine the factors influencing usage intention of Location-Based Advertising (LBA) and moderating effects of gender. This model tests various theoretical research hypotheses relating to LBA, service and individual characteristics, and Technology Acceptance Model (TAM). The target population of this study was LBA users. The results of hypothesis testing are as follows. First, personalization and ubiquity positively influence attitudes toward LBA and irritation negatively influence attitudes toward LBA. Second, coupon proneness and flow experience positively influence attitudes toward LBA. Finally, personalization and ubiquity to attitudes toward LBA for females are significantly larger than those for males. And coupon proneness and flow experience to attitude for males are significantly larger than those for females. The results of this study will provide various implications to improve usage intention of LBA.

VIP marketing strategy is mainly applied to commercial companies. This study proposed a plan to provide preferential services to excellent users of public libraries by referring to VIP marketing strategies. For this purpose, we surveyed 210 university students in their 20s and measured their Reliability, Empathy, overall usefulness for preferential service. As a result, 'Issue special membership card', 'provide exclusive lounge', 'additional book loan' services had common effects on three measurement items. Through these research results, this practical study can be used as a reference when public libraries implement preferential services in the future.

In this paper, we tried to explore factors influencing the diffusion of online events through SNS by analyzing the online footprint of consumers. To this end, log data of online events conducted by "C" beer brands were collected and analyzed. The analysis unit of log data was set for each one hour, and the analyzing method used descriptive and regression analysis. Results are as follows. First, factors influencing the diffusion of the view of SNS-based online events were like, friend used coupon, and friend size. In particular, the size of friends had the greatest impact on the diffusion, which again suggests the importance of social hubs in online events. Second, factors influencing the diffusion of the number of inflows were also like, friend used coupon, and size of friends. Third, it was found that the number of reply did not affect the diffusion of views and inflows. This study is meaningful that it suggested an alternative plan to increase the effect of online events by using real data.

최근 만원권, 오천원권, 백원화 등 화폐의 도안물 그대로 또는 원부 변형하여 신문 및 잡지광고, 할인용 쿠폰, 광고용 전단 등 상업적 광고물에 무단 이용하는 사례가 빈번히 발견되고 있다. 화폐도안을 이용한 광고행위는 화폐의 품위를 손상시킬 뿐만 아니라 일반인으로 하여금 위조화폐 제작 충동을 유발하고 지급수단으로도 악용될 소지가 있어 선진국에서도 일정한 기준 들을 정하여 엄격히 규제하고 있는 실정이다. 이에 따라 한국은행은 1999년 6월 29일 문화관광부에 화폐도안된 한국은행의 저작물로서 등록하여 법적권리를 강화하는 한편 화폐의 품위 유지 및 건전한 신용질서 확립을 위하여 화폐도안을 이용한 광고행위가 발견될 경우 ${\ulcorner}$저작권법${\lrcorner}$에 의한 고소 등의 법적조치를 취할 수 있음을 산업계에 주지시켜 달라는 협조요청을 해왔다. 금호에서는 각 사례별로 저작권 침해사례를 풀이한 협조요청 자료를 게재한다.
