Recently, the combination of mobile and NFC aroused great momentum for Activation of NFC services market. Especially, mCoupon service using NFC has been utilized in a variety consumer marketing. However, mCoupons differ significantly from paper-based coupons because unprotected data can be easily copied or modified without significant cost by anyone. A high number of uncontrolled copies of coupons can result in a significant loss. In this paper, we proposed a light-weight signature scheme that is protected against illegal use in nfc mobile payment environment to using limited resources.

Recently, an application business model was proposed to implement an M-coupon system using the NFC-based mobile devices. In this paper, the security requirements were surveyed for a secure M-coupon system and to analyze the threats on the existing NFC-based M-coupon protocols. After considering the implementation efficiency and security, this paper presents a novel M-coupon protocol based on the Diffie-Hellman key agreement scheme. This protocol can be an alternative to solve the security problems related to the PKI (Public Key Infrastructure) and secret key distribution. Furthermore, this M-coupon protocol is designed to provide user authentication and counteract the relay attack.

As a form of reciprocity or exchange, gift giving is one of the processes that integrate a society. There has been a long history of research on gift giving behavior in the communication area. Recently with the advent of digital environment, digital contents gift giving behavior became a prevalent social custom. But there has been little research of an individual consumer's consumption behavior of digital contents gift giving. Drawing on the innovation theory, technology acceptance model, and gift giving literature, the author take a quantitative approach to the effect of innovation attributes on mobile coupon gift giving behavior. The result showed that innovation attribute did positive influence to mobile coupon gift giving behavior. Furthermore, consumer innovation attribute moderate in the relationship between product innovation and mobile gift giving attitude.

최근에는 많은 스마트폰 어플리케이션이 결제와 할인쿠폰, 적립 등 각종 기능을 제공하면서 사용자들에게 매우 간편한 거래 방식을 제공할 수 있는 NFC 서비스 시장이 성장할 것으로 전망되고 있다. 특히 스마트폰의 NFC 기능을 이용한 여러 서비스들 중 모바일 쿠폰 서비스인 mCoupon 서비스의 시장 활성화를 위해 다양한 인프라가 구축되고 있다. 하지만 mCoupon 서비스는 아직까지 관련 보안 연구가 미흡한 상태이며 보안 기술 개발 속도 또한 현재 구축되고 있는 다양한 인프라에 따라가지 못하고 있다. 따라서 본 논문에서는 NFC 환경에서의 mCoupon 서비스를 위한 안전하고 효율적인 쿠폰 시스템을 설계하고 구현한다.

Purpose of the study is to explore the effect of the types of mobile coupons(text- vs. image-focused coupons; free-gift vs. discount coupons) on characteristic perception of mobile coupons, and the causal relationships among characteristic perception, attitude, and use intention of mobile coupons. A total of 140 university students participated in experiments with questionnaires including one of the four stimuli. Important findings are as follows. First, image-focused mobile coupons generated more enjoyment than did text-focused coupons. However, the text/image-focused coupons were not different in perception of informativeness and credibility of mobile coupons. Second, enjoyment perception was significantly increased when image-focused contents were combined with discount coupons whereas enjoyment perception was decreased when text-focused contents were combined with free-gift coupons. This interaction effect reflects that the level of enjoyment of consumers can be changed in terms of the combination of the value-provision types of coupons and the text-image focused contents. Third, it was found that consumer perception of coupon characteristics formed attitudes toward mobile coupons, and use intention of mobile coupons was determined by attitudes toward mobile coupons. Study findings may fill the void of research investigating the effect of text-image contents and the types of coupons on consumer reponses toward mobile coupons. Mobile coupons have limited quantity of information within a small size of mobile phone screen, therefore, the results were not consistent with prior research tested with mobile advertisements indicating the effect of text-image contents on perception of informativeness and credibility.

The purpose of this study was to understand how consumers perceive the costs of couponing by coupon types and to suggest ways in which coupons should be developed to contribute to consumers' welfare. Costs/benefits of coupons as the most close antecedent variable included the following 8 constructs: searching costs, clipping costs, storing costs, extra expenses, substitution costs, pressure of holding, uncomfortable feelings, and regrets. Since it was hypothesized that the cost of couponing differs by coupon type, four coupon-types were examined: homepage coupon, E-mail coupon, DM coupon, and newspaper/magazine coupon. Data for this research were collected through 732 responses to a self-administered survey of consumers who had used all four types of coupons requesting participation from members of Internet survey firm. The conclusions of this research can be summarized as follows: (1) Women preferred off-line coupons but men preferred on-line coupons. In addition, consumers in Seoul were more familiar and satisfied with on-line coupons than consumers in other regions. (2) Among constructs of costs, consumers perceived regrets, pressure of holding, and substitution costs highly. Differently from previous studies, consumers perceived searching costs and clipping costs to be less important than other costs. (3) Storing costs, pressure of holding, and uncomfortable feelings were higher in off-line coupons, whereas clipping costs, extra expenses, and substitution costs were higher in on-line coupons. (4) In general, most constructs of costs in using homepage and newspaper/magazine coupons were higher than those of E-mail and DM coupons. (5) Cost perception was negatively related to coupon satisfaction at coupon, except newspaper/magazine coupon which was the least satisfactory coupon, regardless of costs (6) Consumers were more satisfied with direct-distribution coupons such as E-mail and DM coupons than public-distribution coupons such as homepage and newspaper/magazine coupons.

본 연구는, 그 동안 간과되어 왔던 의류 상품의 판촉에 초점을 맞추어, 판촉의 여러 방법 별 소비자들의 반응 정도를 알아보고, 그 반응 경향이 소비자의 인구통계적 특성, 판촉에 대한 태도, 의복 쇼핑 성향, 기타 의복 구매 행동과 연관성을 가지는지를 규명함을 목적으로 한다. 수도권 거주 여성 444명을 대상으로 수집한 자료를 이용해 분석이 이루어졌다. 실증적 연구를 통해 다음과 같은 결과를 얻었다. 첫째, 판촉의 각 방법에 대한 소비자들의 반응 정도는 가격 할인이 가장 높았고 그 다음은 디스플레이, 쿠폰, 사은품, 백화점 패션쇼, 경품의 순서로 나타났다. 가격 할인, 디스플레이, 사은품, 쿠폰, 백화점 패션쇼 등 5가지 판촉 방법에 대한 소비자 반응 정도를 기준으로 군집분석한 결과 판촉에 대한 반응 유형에 있어 차이를 보이는 5개 집단을 규명할 수 있었다. 각 집단의 인구통계적 특성들 중에서는 소비자 자신의 학력과 자녀의 연령만이 집단간에 유의한 차이를 보였으며, 각 집단의 판촉 태도는 집단 간에 유의한 차이를 보였다. 둘째, 각 집단은 의복 쇼핑 성향 및 의복 구매 관련 정보원 이용에서 차이를 보였다. 결론에서는, 실증적 연구의 결과 판촉에 대한 소비자 반응 유형별로 인구통계적 특성, 판촉 태도, 의복 쇼핑 성향, 기타 의복 구매 행동에 차이가 있음을 알 수 있었으므로 의류 상품의 판촉 전략 수립시 표적 집단의 특성에 따라 판촉 방법 선택이나 판촉 정보 전달 경로 등을 조절하는 것이 필요함을 제언하였다. 예를 들어, 신중/경제적 쇼핑 성향을 가지며 판촉에 대한 태도가 호의적인 소비자들에 대해서는 다양한 정보 전달 경로를 통해 가격 할인이나 쿠폰을 제공하는 것이 좋은 판촉 방법이 될 것이며, 쾌락/유행 지향적이고 상표/품질을 중시하는 소비자들에 대해서는 잡지, 인적 정보, 카탈로그 등을 정보 전달 경로로 하여 디스플레이나 패션쇼를 통해 판매 촉진을 할 수 있을 것이다.0.10 $h^{-1}$과 0.09$h^{-1}$h-1이었고, 반감기는 각각 6.93 및 7.70시간으로 측정되었다. 각각의 농도에서 12시간 및 8시간 이후에는 g당 0.19$\mu\textrm{g}$ 및 0.18$\mu\textrm{g}$이하로 떨어짐을 알 수 있었다. Phosphamidon과 profenofos의 급성어독성은 profenofos가 높았고, BCF profenofos가 phosphamidon보다 약 100배 정도 높게 나타났으며, 배설속도는 phosphamidon이 profenofos보다 약 2배 정도 빨랐다.

This paper studies current market of smart phone game and suggests the new earning model. In paper, it is not just for spending free time but seeking profits to play game. Making profits is operated in mutual beneficial way. First, a partnership company cooperates with a game company. And then the partnership company issues coupons about its product which game players can get in game and can use in real. by this way, the partnership company can expect the advertising effect. Besides, game company can spare some burden about earning by cooperation. Eventually It is respected that users spend their money and purchase products with coupon they get in game on offline shop. In this paper, the earning model is integrated in real platform and explain the process.
