기업들이 고객에 대해 관심을 가지는 이유는 고객관계관리(CRM: customer relationship management)의 중요성이 그 어느 때 보다도 강조되고 있기 때문이며, 또한 강력한 고객관계가 기업의 경쟁우위를 위한 주요 수단이 되고 있음을 지각하고 있기 때문이다. 특히 인터넷 쇼핑몰에 대한 고객의 충성행위는 인터넷 쇼핑몰이 제공하는 다양한 상품 및 서비스와 더불어 성공적인 고객관계를 위해서는 매우 중요하다. 또한 인터넷 쇼핑몰의 입장에서는 여러 가지 다양한 서비스를 인터넷 쇼핑몰 이용 고객에게 제공함으로써 인터넷 쇼핑몰을 이용하는 고객들에 대한 신뢰와 몰입을 증가시킴으로써 인터넷 쇼핑몰 이용 고객들로 하여금 인터넷 쇼핑몰에 대해 높은 충성도를 가지게 할 수 있을 것이다. 따라서 본 연구는 인터넷 쇼핑몰 이용 고객에 대한 고객충성행위를 신뢰형성요인, 몰입형성요인, 신뢰, 몰입이라는 측면에서 설명하고자 하였다. 즉, 인터넷 쇼핑몰의 신뢰형성요인(능력, 호의성, 무결성)이 신뢰에 영향을 미치고, 몰입형성요인(촉진정보, 상호작용성, 쇼핑몰디자인)이 몰입에 영향을 미친다. 그리고 신뢰는 몰입과 고객충성행위에, 몰입은 고객충성행위에 영향을 미칠 수 있음을 제안하고 이를 인터넷 쇼핑몰 이용 경험이 있는 고객들을 대상으로 실증적으로 분석하였다. 실증분석 결과에 따르면 제안모델은 수용가능한 모델적합도를 보여 주었으며, 또한 본 연구에서 제시한 9개의 가설 모두가 통계적으로 유의한 결과를 보여주었다. 특히 신뢰는 신뢰형성요인(능력, 호의성, 무결성)과 고객충성행위사이에 매개변수의 역할을 수행하고있으며, 몰입은 몰입형성요인(촉진정보, 상호작용성, 쇼핑몰디자인)과 고객충성행위사이 그리고 신뢰와 고객충성행위사이에 매개변수의 역할을 수행하는 것으로 나타났다.동지역의 고기후를 해석함으로써 고기후적 및 고생태학적 의미를 연구해 보고자 하였다.에서는 시스템 등급에 영향을 준다. 향후에는 더욱 더 다양한 상호의존 모델들이 정량화될 필요성이 있다고 본다. 진행하였다. 줄여서 보다 더 정확하고, 지능적인 규칙구성요소 추출 방법론을 제시하고 구현하여 지식관리자의 규칙습득에 대한 부담을 줄여 주고자 한다. 도움을 받을 수 있게 되었다.을 거치도록 되어있다. 교통주제도는 국가의 교통정책결정과 관련분야의 기초자료로서 다양하게 활용되고 있으며, 특히 ITS 노드/링크 기본지도로 활용되는 등 교통 분야의 중요한 지리정보로서 구축되고 있다..20{\pm}0.37L$, 72시간에 $1.33{\pm}0.33L$로 유의한 차이를 보였으므로(F=6.153, P=0.004), 술 후 폐환기능 회복에 효과가 있다. 4) 실험군과 대조군의 수술 후 노력성 폐활량은 수술 후 72시간에서 실험군이 $1.90{\pm}0.61L$, 대조군이 $1.51{\pm}0.38L$로 유의한 차이를 보였다(t=2.620, P=0.013). 5) 실험군과 대조군의 수술 후 일초 노력성 호기량은 수술 후 24시간에서 $1.33{\pm}0.56L,\;1.00{\ge}0.28L$로 유의한 차이를 보였고(t=2.530, P=0.017), 술 후 72시간에서 $1.72{\pm}0.65L,\;1.33{\pm}0.3L$로 유의한 차이를 보였다(t=2.540, P=0.016). 6) 대상자의 술 후 폐환기능에 영향을 미치는 요인은 성별로 나타났다. 이에 따른 폐환기능의 차이를 보면, 실험군의 술 후 노력성 폐활량이 48시간에 남자($1.78{\pm}0.61L$

Conventional research on customer relationship management(CRM) in general has focused on the effects of individual customer's satisfaction, retention and profit management. However, corporate customers are more profitable than individual customers because of high volume and frequent transactions between companies. In this article, a prototype for a corporate customer relationship management is developed in the postal service. First, the frequency and amount of customers' usage were examined, and thereby the corporate customer rating scheme was established to provide customized service. Second, five different types of usage patterns were determined using clustering analysis. In addition, we presented the rationales behind the five types of patterns. Third, RFM(recency, frequency, monetary) analysis was performed, and then action plans were developed to increase sales. Finally, the prototype software was developed to automatically perform the above analysis using MS Excel program.

인터넷 비즈니스나 전자상거래와 연관되어 고객관계관리 (Customer Relationship Management: CRM)가 널리 확산됨으로 해서 군집분석에 대한 관심이 한층 높아졌고, 다양한 군집분석 프로그램이 시장에 소개되어 지고 있다. 그러나, 군집분석 프로그램들은 다른 데이터 분석 기법과는 달리 그들의 정확성을 측정하기가 매우 힘들다. 본 논문에서는 이미 알려져 있는 군집구조를 지닌 인위적 데이터를 사용하여 반복적 군집분석 프로그램 (Convergent Cluster Analysis: CCA)과 보다 전통적인 단순군집 프로그램 (One-Shot Clustering Program: Howard-Harris 프로그램), 그리고 데이터 마이닝 기법 중의 하나인 데모그래픽 군집분실 프로그램의 정확성을 비교하기 위한 현재 진행 중인 연구의 방법론을 제시하는데 그 주요 목적을 두고 있다.

Decision tree is one of the most useful analysis methods for various data mining functions, including prediction, classification, etc, from massive data. Decision tree grows by splitting nodes, during which the purity increases. It is needed to stop splitting nodes when the purity does not increase effectively or new leaves does not contain meaningful number of records. Pruning is done if a branch does not show certain level of performance. By pruning, the structure of decision tree is changed and it is implied that the previous splitting of the parent node was not effective. It is also implied that the splitting of the ancestor nodes were not effective and the choices of attributes and criteria in splitting them were not successful. It should be noticed that new attributes or criteria might be selected to split such nodes for better tries. In this paper, we suggest a procedure to modify decision tree by Fuzzy theory and splitting as an integrated approach.
