This paper suggests a heuristic algorithm for the clustering problem. Clustering involves grouping similar objects into a cluster. Clustering is used in a wide variety of fields including data mining, marketing, and biology. Until now there are a lot of approaches using Self-Organizing Feature Maps(SOFMs). But they have problems with a small output-layer nodes and initial weight. For example, one of them is a one-dimension map of k output-layer nodes, if they want to make k clusters. This approach has problems to classify elaboratively. This paper suggests one-dimensional output-layer nodes in SOFMs. The number of output-layer nodes is more than those of clusters intended to find and the order of output-layer nodes is ascending in the sum of the output-layer node's weight. We can find input data in SOFMs output node and classify input data in output nodes using Euclidean distance. We use the well known IRIS data as an experimental data. Unsupervised clustering of IRIS data typically results in 15 - 17 clustering error. However, the proposed algorithm has only six clustering errors.

Past and current customer behavior is the best predicator of future customer behavior. This paper introduces a procedure on personalized defection detection and prevention for an online game site. The basic idea for our defection detection and prevention is adopted from the observation that potential defectors have a tendency to take a couple of months or weeks to gradually change their behavior (i.e. trim-out their usage volume) before their eventual withdrawal. For this purpose, we suggest a SOM (Self-Organizing Map) based procedure to determine the possible states of customer behavior from past behavior data. Based on this representation of the state of behavior, potential defectors are detected by comparing their monitored trajectories of behavior states with frequent and confident trajectories of past defectors. The key feature of this study includes a defection prevention procedure which recommends the desirable behavior state for the ext period so as to lower the likelihood of defection. The defection prevention procedure can be used to design a marketing campaign on an individual basis because it provides desirable behavior patterns for the next period. The experiments demonstrate that our approach is effective for defection prevention and efficient for defection detection because it predicts potential defectors without deterioration of prediction accuracy compared to that of the MLP (Multi-Layer Perceptron) neural network.

The Healthy Family Act was established in 2004 to prevent problems of the family and increase thehealthy characteristic of the general family. According to this Act, Healthy Family Support Centers (HFSCs) were founded as a new part of the family welfare institution. The purpose of HFSCs is providing various welfare services to enhance the health and well-being of families in the community. This study investigated the organizational system and evaluation strategies of HFSCs. This research comprised a descriptive study of the organizational system and evaluation strategies of HFSC. The study sample consisted of 217 faculty and field workers. Data were collected from December 2004 to January 2005 and analyzed by frequencies, mean, standard deviation and ANOVA. The results were as follows. First, HFSC's organization should consist of family education, family counseling, family culture-marketing, and network teams. Second, healthy family specialists should have a national certificate of qualifications also they should have more than master's degree level. Third, evaluation of HFSCs should be adapt an incentive system.

There is an expanding global network of free trade agreements (FTA). High-quality, comprehensive free trade agreements play an important role to support global trade liberalization and are explicitly allowed under the World Trade Organization (WTO) rules. An FTA is an international treaty that removes barriers to trade and facilitates stronger trade and commercial ties that contribute to increased economic integration between participating countries. Korea benefits from the global FTA trend; however it has started and developed FTA negotiations later than other countries. Current FTA agreements exist with Chile, Singapore, EFTA, ASIAN, India, EU, Peru, USA, Turkey, Australia, and Canada; in addition, there are ongoing negotiations with China, Colombia, New Zealand, and Vietnam. FTA open up opportunities for the textile/clothing industry to expand businesses into key overseas markets. FTA improve market access across all areas of trade to help maintain and stimulate the competitiveness of textile/clothing firms. This study examines the expansion of free trade agreements in light of changes in the international trade environment and the status of the Korean textile/clothing industry. Korea's textile/clothing export/import products and concession of tariff, country of origin covered under Korea-US/China FTA are investigated to identify problems. This study provides practical and policy implications for the textile/clothing industry in regards to the Korea-US/China FTA.

There are positive evaluation as well as negative evaluation for Rural Industrial Park Project which was implemented since 1984 to boom up the regional economy in Korea. By conducting a survey for Rural Industrial Park enterprises located in Miryang-si, this study intends to examine the management condition of enterprises in Rural Industrial Parks and so derive the policy suggestion. According to the secondary data and the survey results, Rural Industrial Parks play an important role in the regional economy. The result of the survey shows that the enterprises are dissatisfied with excessively high distributing costs and they want improvement of roads and transportation condition. They recruit their employees mainly through advertisement and loan money from banks. One of serious problems is giving up the business due to shortage of fund or failing to find the markets. To prevent quitting business, a preliminary analysis of the feasibility of running business should be conducted. Technology and management guidance and marketing support are necessary not only for new enterprises, but for existing enterprises. Alternatives for connecting local resources and Rural Industrial Park and forming a network between local universities, institutes, and firms should be considered.

As the Internet is more embedded in people's lives, users draw on new Internet applications to express themselves through user-created contents(UCC). UCC is defined as content that is made publicly available over the Internet, reflects a certain amount of creative effort and is created outside of professional practices. This study describes the rapid growth of UCC as well as its increasing role in network-based communication. Based on the definition of UCC and the structure of emerging value chain, a taxonomy of UCC businesses is presented : UCC e-marketing business, UCC publishing business, UCC e-retailing business, and UCC development software business. This paper concludes with implications for platform and internet access providers.

This case describes key development challenges and patterns as experienced by Internet Auction Company, Ltd. from the startup stage through IPO to the sale to eBay. Currently an eBay company, Internet Auction Co. continues to pursue new auction systems and substitute distribution systems for the future with a renewed entrepreneurial spirit. In 1997, Mr Hyuk Oh saw a business opportunity in the Internet allowing two-way communications. At that time, the success stories of eBay and Onsale in the United States were good stimuli to his startup of an auction site. He opened the Website in April 1, 1998 after four months of development efforts. Auction has merit more than other shopping malls. First, it brings about interesting and benefit. Second, it has interactive trade system. Third, customers will trade for reasonable price through direct own will of them. Fourth, Auction's model brings about multitude sale through aggressive sales. Even if Network Marketing has socially negative effect in case of inappropriate use, it is good mood for further business. In case E-Commerce use as useful purpose, it will have competitive priority revenue model.

The concept of district heating involves centralised heat production where heat is distributed to consumer via a piping network. The objective of this work is to identify the Flexible Pipe from an economy, execution, maintenance point of view. Flexible Pipe has in some countries, especially in Europe, been used for many years in district heating. In spite of years of experience, there still exist doubts about the possibilities of using flexible pipes in district heating applications, mostly because of no experiences in domestic market. The advantage of flexible pipe systems is their flexibility. This holds not only for the inner pipe but also for the total pipe system including insulation and jacket. Even for the largest diameter the minimum radius of curvature is given to 1.5m. The most important difference between flexible pipe systems and preinsulated steel pipes is their simple and quick assembly. Such information could provide a basis for making reasonable hypotheses about consumer preferences, to foam a basis for making future marketing more effective.
