In this research, we segment customers for customer relationship management in the Internet shopping mall. The RFM, FRAT, regression analysis, discrimination analysis, decision tree, neural networks are used for customer segmentation. Previous researches about the customer segmentation by RFM were conducted based on the assumption that customers purchasing pattern is consistent. However customers purchasing pattern dynamically changes in real. To overcome these changes of purchasing pattern and establish more effective marketing strategy for customers, we suggested the customer segmentation method by period considered RFM and described the marketing strategy with the results of customer segmentation. For an example, P Internet shopping mall was used.

본 연구에서는 동물복지형 축산물의 경제적 가치를 국내외의 선행연구를 통하여 알아보고자 하였다. 이 연구를 위하여 국내 외에서 발간된 다양한 연구결과를 참고하였다. 분석결과 국내 외 모두 이 분야에 대한 연구가 그리 활발하지 않다는 점을 발견하였다. 분석은 소고기, 돼지고기, 닭고기, 칠면조고기 등의 육류와 계란에 대한 소비자들의 의식조사가 주를 이루고 있었다. 여기에 사용된 데이터는 설문조사를 통한 데이터가 주를 이루고 있었으며, Lexis-Nexis databases, 소고기, 돼지고기, 가금육, 비육류 식품에 대한 분기별 소비량과 소비자가격, 그리고 경매실험을 통한 데이터 등이 사용되었다. 한편, 분석모형으로는 Random parameters logit and latent c1ass model, WTP 분석, Roterdam model, Pearson's Chi test, Mann-Whitney U-test, Kruskal-Wallis test, structural equation model, 회귀분석, Target-costing, 그리고 conjoint 분석 등이 사용되었다. The purpose of the study is to review current studies for economic values on livestock products produced by animal welfare.

The object of this study is to establish proper consumer-oriented advertisement strategies of animal welfare egg. Data were collected by consumer survey on November 4th, 2011 at Hanaromart in Chunchon area. SAS 9.1 and Excel 2007 were used as statistical package and ranked logit model was used to analyze the data. From the results of the study the following advertisement strategies were suggested for animal welfare egg considering the effects of advertisement media. First, internet based media were most preferred. For effectively using the internet based media the message should be succinctly and clearly transferred to consumers. Therefore if phrases and pictures emphasizing the difference between animal welfare egg and general egg were used, then positive effects could be attained from consumers in a short period. Second, advertisement media should be used differently based upon the consumers" income level. In the case of consumers under three million won income level the advertisement in the purchasing site was most effective regarding the advertisement effects. Therefore if the advertisement showing the breeding surroundings between animal welfare egg and general egg was used, positive effects could be attained. For consumers over three million won income level the homepage of egg producers was most effective in advertisement. So if more accurate information were distributed to consumers visiting the homepage and high quality egg were sold via the homepage, positive effects could be attained.
