Acquired pigmentary skin diseases such as abnormal melanogenesis, vitiligo, chloasma and inflammatory pigmentation are related to regulate the melanin production. The aim of this study was to investigate the effect of Codonopsis lanceolata on the melanogenesis of HM3KO human melanoma cells biologically. The cells were treated for 5 days with Codonopsis lanceolata at several concentrations. Treatment with Codonopsis lanceolata suppressed melanin contents as a dose dependent manner without cytotoxicity and morphological change. And the extract of Codonopsis lanceolata also inhibited tyrosinase, a key enzyme forming melanin, in a dose-dependent manner. And it did not affect the DOPAchrome tautomerase(TRP-2) activity. These results suggest that Codonopsis lanceolata is a candidate for an efficient whitening agent which supresses melanogenesis by a Raper-Mason pathway.

Customer`s purchase state consists of purchase inertia and variety-seeking. As the growing brand familiarity triggers the increase of brand attractiveness, customers purchase state will be of inertia. However the excessively growing brand familiarity ignites the decrease of brand attractiveness. Followingly the purchase state will be tend to plunge into the variety-seeking state. The main topic of this study is to validate the asymmetric formation of customer`s purchase states between inertia and variety-seeking. In order to follow up the main topic, this article introduces a model to freely describe the velocity of value changes depending upon the purchase states. This model will help overcome the limitation of the past studies having been based on the symmetric value changes. Based on this approach marketer will be able to decide the timing of sales promotions. This research utilized local telecommunication carrier`s database of smartphone application purchase/download records. This database was collected from two years (2009 and 2010) span, the time when the smartphones started commodifying in Korea whilst most of the past studies had used purchase data of maturity stage products. From this approach utilizing the introduction stage data in the product life cycle, the probability of brand choice depending upon the purchase state on the early-stage can be probed. Moreover, this study tries to expand the research methodology from the other areas of research by knowledge sharing. Here this study introduces the methodology of section-aggregated multinomial logit to simultaneously estimate the parameters that were included in the plural multinomial logit functions while the plural functions were inter-connected. This adoption of section-aggregated multinomial logit model procedures from the computerized statistics areas is expected to nourish the marketing research for more precise analysis and estimation of effects of marketing activities.

이승연(Seung Yon Lee) 한국마케팅학회 2010 마케팅연구 Vol.25 No.3

로열티 프로그램에서 제공되고 있는 보상물은 고객확보를 위한 판매촉진 수단으로 점차 각광 받고 있어 기업체의 입장이 반영된 효율적인 보상물 선정에 관한 연구의 필요성이 대두되고 있다. 기존 연구에서 보상물의 효과를 상승시키기 위해 선택해야 할 보상물의 제공시점 및 유형에 대하여 언급하고 있으나, 기업체는 상황에 따라 보상물의 제공시점 및 유형에 대해 가장 효과적이라고 기존 연구에서 주장하는 조합이 아닌 다른 조합을 선택하기도 한다. 이는 기업체의 마케팅목표를 위하여 또는 기업체의 비용구조상의 이유로 특정 제공시점 또는 특정 유형을 선택하고자 하는 경우가 발생하기 때문이다. 이 때 기업이 보유한 브랜드의 명성을 고려하게 되면, 보다 효과적으로 로열티 프로그램을 실행할 수 있음을 제안하고자 한다. 본 연구 결과를 통해, 즉각적 시점의 보상물을 제공해야 할 경우는 자사 브랜드 명성을 고려하여 보상물의 유형을 결정하여야 하고, 지연적 시점의 보상물을 제공해야 할 경우는 브랜드 명성에 상관없이 기업의 비용구조상 유리한 보상물의 유형을 선택해도 무관함을 알 수 있었다. 또한 직접적 유형의 보상물을 제공해야 할 경우는 자사 브랜드 명성을 고려하여 보상물의 제공시점을 결정하여야 하고, 간접적 유형의 보상물을 제공할 경우는 브랜드 명성에 상관없이 기업의 마케팅목표에 유리한 보상물의 제공시점을 선택해도 무관함을 발견 할 수 있었다. 본 연구는 로열티 프로그램으로 제공되는 보상물의 객관적 가치를 밝히는 것 뿐 아니라 기업입장에서 누릴 수 있는 순효과를 고려한 보상물 제공시점 및 유형 선정에 대한 의사결정기준을 제시하였다. 이로써 본 연구는 실무적으로는 기업체의 보다 효율적인 예산 집행에 기여하고 학문적으로는 차별적인 로열티 프로그램의 효과를 발생케 하는 요인을 밝힘으로써 로열티 프로그램 연구의 발전에 기여하리라 기대된다. It is essential to research on the effect of rewards since reward of loyalty program is currently seen as a comparative edge of marketing activities. Companies choose many other varieties of reward combinations for reward types and timing after the previous researches presented and specified certain types and timing of rewards to enhance the effect of rewards. Companies tend to pursue their specifically own type or timing of rewards since they need to meet their internal marketing goal or sometimes try to save expenses. This research suggests how rewards of loyalty programs can be efficiently managed by considering the moderating effect of the brand reputation. This research is to show the criteria for the reward offering and shows the hypotheses of: (1) The main effect of reward timing and type to the reward evaluation, (2) the moderating effect of brand reputations to the main effect, (3) the interaction effect between reward timing and reward type, (4) the moderating effect of brand reputation to the interaction effect. This research adopts the 2x2x2 factorial design of reward types (direct, indirect), reward timing(immediate, delayed), and brand reputation (high, low). Further, dependent variable takes reward evaluation in order to prove the effects of reward. Experimental materials takes the coffee coupon that is the common loyalty program in the coffee retailers with high frequency of customers` visit. 8 stimulant coupons based on the reward type, timing, and brand reputation were created. 8 scenarios of reward type (direct, indirect), timing (immediate, delayed), and brand reputation (high, low) were responded by approximately 40 participants per each scenario. There were some outliers of respondents, exchange students, that were left out. Thus total 342 respondents were analyzed in this outcome. The outcomes of hypothesis testing and the implication of this research were summarized here. The main effect of reward timing and types to the customers` evaluation was observed in line with that of Rothschild and Gaidis(1981). As reward timing is more delayed and type is more indirect, customers` evaluation of reward decreases. The implications from the result of the moderating effect of brand reputation to the main effect was experimented is that if brand reputation is high enough, immediate or delayed timing of reward does not have differences. However, if the brand reputation is low delayed reward timing should be avoided. Hence, if a company needs to offer rewards in delayed timing it should want to promote for the products with higher brand reputation. On the other hand, if the brand reputation is high enough direct or indirect type of rewards does not have differences as we observed on the timing decision. However if the brand reputation is low, companies might avoid the indirect type of reward. Thus, if there is some obtainable indirect type of rewards at a low cost the company should focus this reward type on the highly reputed brands in order to increase the net effect of rewards. The implications of the interaction effect that affect the customers` rewards evaluation between reward timing and reward type are that if companies are required to offer the rewards in delayed timing, they may take the rewards at the lowest cost regardless of direct or indirect type, and if companies are required to offer rewards immediately, direct reward type will be more beneficial (on condition that direct and indirect type has no cost differences) Also if companies are in a good position to obtain indirect type of rewards at a lower cost, immediate timing or delayed timing decision should be depending upon the company`s strategic goal of marketing, and if companies can obtain direct type of rewards at a lower cost, immediate timing of rewards will be more effective. This research reached the main conclusion by observing the brand reputation`s moderating effect on the interaction effects. In terms of reward timing, when a company wants

오늘날 업계에서 CRM활동의 일환으로 우량고객들을 별도로 선정하여 특별관리하는 경우를 흔히 볼 수 있다. 이들은 마케팅비용을 최적화하기 위하여 여러 세분시장들 가운데 우량고객시장을 선별하여, 이들에게 집중적으로 예산을 할당하는 로열티 프로그램을 시행하고 있다. CRM에 대한 업계의 관심이 고조됨과 함께, 학술적으로도 로열티 프로그램의 효과에 관한 연구가 활발하게 진행되고 있으나, 기존연구들의 상반된 결과들을 해석할 수 있는 실마리가 제공되지 못하고 있는 실정이다. 본 연구에서는 국내 대형 백화점에서 로열티 프로그램의 일종인 VIP 프로그램이 처음으로 시행된 시점 전후의 거래기록 및 마케팅활동 기록을 사용하여 VIP 프로그램의 효과를 직접적으로 포착하였다. 이로써 소비자의 로열티 성향에 따른 VIP 프로그램의 차별적 효과를 분석하고, 기존 연구들의 모순되는 결과에 대한 해답을 제시하였다. 본 연구는 현재 업계가 행동적 측면만을 기준으로 삼아 우량고객을 선정하는 방식에 대한 문제점을 지적하고, 보다 효율적인 마케팅 비용 집행을 위한 지침을 제공하는데 의의가 있다.

Recent market saturation makes the local retailers consider an attempt to innovate the market with the retailer`s brand. This is the retailers` efforts to expand the market control through the enhancement of private brands. As the competition among manufacturers extends to the competition between manufacturers and retailers, the marketing knowledges of manufacturers need to be diversified to the ones that can be applied to the manufacturers and retailers due to their bilateral competition. This research concentrates on the customer acquisition strategy (attack strategy) and customer retention strategy (defense strategy) in the place of both sides of manufacturers and retailers. Also this research targets to develop the differential marketing strategies for target market`s National Brand(NB)/Private Brand(PB) purchase by analyzing individual customer`s purchase probability on repurchase and switch-purchase of NB and PB. This study is based on the data of frequently consumed product, tomato ketchup on scanner panel from the ERIM data of University of Chicago, USA. This study compares and analyzes the NB and PB repurchases and switch-purchase of 4 types. The comparisons provide the informations that which factors should be managed for the attack strategy, the defense strategy, and the differential marketing strategies both for manufacturers and retailers. This research is expected to contribute on cumulating the industrial knowledges of retailers` and manufacturers` survival strategy, expecially focusing on the effect of marketing factors and consumer-characteristic factors.

The mass media provides us with a wide range of information easily and quickly. Thanks to this, many people can share their techniques about beauty and it has been helped for the beauty industry to grow rapidly. The emphasis was on colors and eyebrow shapes, however, dewy textured skin makeup was born with 'the no makeup face' craze, the techniques of skin texture has made new trends and developed gradually over the years. As advanced studies on makeup techniques for skin texture have been limited since 2006, the research was conducted to find new makeup techniques by reading beauty books and looking into cosmetic web sites and cable channels. Through the research, followings are newly born techniques that were not seen before 2006: dewy, shiny and honey textured skin makeup. They use essence, pearl makeup base, balm products when applying foundation instead of powder. They make skin look moist, glow and glossy instead of soft and dry. Another glowing textured skin technique is a semi matte makeup which is differ from above-mentioned techniques. It focused on covering blemishes, uneven skin and pores. The latest technique called moist and shiny textured skin gives natural glossy look from the inside of skin not from the surface like dewy, shiny and honeyed textured skin techniques. Based on diverse makeup techniques, further researches have been carried out to remove weaknesses and improve their skills. There is much attention toward the future textured skin makeup techniques and the researcher hopes for people to keep their studies on various techniques for skin texture.
