경매는 인간에 의해 만들어진 복잡한 형태 시장이다. 전자상거래의 확산과 더불어, 많은 인터넷 경매 사이트가 나오고, 최근 경매의 자동화에 대한 연구가 진행 중에 있다. 인간 대신, 에이전트는 상품의 검색, 입찰등을 대신 수행하게 된다. 그러나, 현재의 입찰 알고리즘은 효율적이지 못하다. 본 연구는 통계적 방법을 이용하여 현재의 알고리즘보다 효율적인 알고리즘을 만들고자 한다.

As the interest in the combinatorial auction has increased, diverse combinatorial auction market types have been proposed. Although there have been several studies on the combinatorial auction design, the studies covered some factors or partial dimensions of combinatorial auction design. Given the potential practical value of combinatorial auctions, it is necessary to approach it with an integrated and systematic design methodology for supporting a comprehensive range of combinatorial auction models. Thus, we present a systematic framework for combinatorial auction design methodology. In particular, we classified the combinatorial auction architecture types, process types, and mechanism types. This framework characterizes the different combinatorial auction models, and lead to a useful taxonomy of the combinatorial auction design factors and taxonomy of the market types by coordination among the design factors. In addition, we illustrate an n-bilateral combinatorial auction market, derived from our design methodology, to show the viability of our study.

To access massive and various HTML documents that are in the web using wireless Internet equipments, another WML document that is equal to the HTML document must be written. In the case Web documents written by HTML are massive, the construction of a WML site with the same information needs much cost of space and time. This paper designs and implements the HTML-XML converter that alleviates such a problem. The HTML-XML converter translates the Web document written by HTML to the WML document for portable wireless equipments. The HTML-XML converter has advantages that it reconstructs WML document dynamically according to portable wireless equipments and processes various image formats such as GIF, JPG, BMP, and so on. The HTML-WML converter can be used as not only a utility of the WML editor but also a real time converter on wireless internet.

Recently, some of people are keep in research and development of the further more efficient and convenient auction systems using intelligent software agents in electronic commerce. The purpose of this thesis is that a simple auction system has web bulletin boards, is aided by intelligent agent, and generates pertinent auction duration time and starting price for auction goods of auctioneer into a auction system, then the auctioneer gets the highest margin. The seller who want to sell goods, is using internet sends mail that has information for goods to agent of internet auction system. The agent undertake filtering process for already learned information about similar goods. And it calculate duration time and start price from stored bidding history database. In this thesis we propose a mailing agent system pushing information in internet auction that enables to aid decision for auctioneer about the starting time and price which delivers the highest margin.

지난 1988년 4월 국내 최초로 인터넷 경매 서비스를 선보인 옥션(대표 박주만 www.auction.co.kr)은 한국 전자상거래의 발전과 함께 성장해 온 대표적인 '온라인 마켓플레이스'이다. 옥션은 국내 최초로 인터넷 경매 사이트를 시작한 기업으로 8년 사이에 국내 최대 전자상거래 업체로 자리잡아 왔다. 최근 옥션은 마켓플레이스 방식과 더불어 일반 쇼핑몰들의 판매방식을 흡수하면서 진화하고 있다. 올해 들어서는 홈페이지를 정비하고, 각종 상품 기획전 등을 개최하며 차별화된 서비스를 진행하고 있다.

본 논문에서는 인터넷 경매 비즈니스의 특징적 요소를 정의하고 이를 기준으로 인터넷 경매 사이트를 분류, 평가할 수 있는 비즈니스 모델을 제안하였다. 먼저 기존 인터넷 사이트들에 대한 현황 분석을 통한 특징적 요소를 도출하고 이를 기준으로 인터넷 사이트들의 세 가지 형태에 대한 비교 모델을 제시하였다. 그리고 이러한 세 가지 형태의 인터넷 경매 모델을 공통으로 설명할 수 있는 비즈니스 모델을 구성하였다. 제안된 인터넷 경매 비즈니스 모델은 비용(Cost), 고객(Netizen), 기술, 거래(Transaction), 그리고 마케팅 등 다섯 가지 요소로 구성되며, 각각의 요소들에 대한 특성 및 분석 방법을 제시하여, 인터넷 경매 사이트들에 대한 평가 도구로서의 이용 가능성을 높이고자 하였다.

요즘 전자상거래의 활성화로 전 세계적으로 인터넷 쇼핑몰과 경매 사이트를 운영하는 곳이 많이 있다. 하지만 사용하던 물건을 팔고 새로운 상품을 구매하려고 한다면 일반적으로 중고 물건을 파는 사이트를 찾아서 그곳에서 물건을 팔고 다시 다른 인터넷 쇼핑몰에서 물건을 사야하는 번거러움이 있다. 그리고 쇼핑몰 사이트의 관리자 입장에서는 판매부진상품이나 이원상품 등을 관리하기 어렵다. 또 기존에 구축되어 있는 맡은 쇼핑몰과 경매사이트의 데이터베이스의 활용도를 보면 저장된 상품을 보여주고. 판매가 되면 삭제되는 역할에 국한된 경우가 많다. 본 논문에서는 전자상거래의 사용자가 인터넷을 보다 간편하게 이용하고 사용자가 등록한 중고물품, 쇼핑몰의 판매부진상품, 이월상품의 경매로 인한 구매자의 참여를 위해 쇼핑몰과 경매 사이트를 통합하여 운영하고, 지금까지의 공통적이고 일반적인 내용의 E-mail 마케팅을 데이터 베이스 통계분석에 의해 차별화 되고 집중적인 E-mail 마케팅으로 구현한다.

In this paper, we propose an efficient and secure sealed-bid auction protocol with two servers, a seller S and a third party A . The proposed scheme uses the idea of the conditional oblivious transfer protocol proposed by Crescenzo-Ostrovskey-Rajagopalan. A server A is not a trusted third party, but is assumed not to collude with a server S. In the proposed auction protocol, barring collusion between A and S, neither party gains any information about the bids, and moreover, the outcome of the auction will be correct. And the computational complexity of our auction protocol is considerably efficient and the communication overhead is similar to that of Naor-Pinkas-Sumner's scheme.

The topic on Flow is generating increased interests in e-commerce studies. Flow has been identified as a key component in e-commerce. Studies on Flow have so far focused on internet shopping mall, but scarcely looked at the Flow of Internet auction. The purpose of study is to find out which factors play a major role in building Flow on internet auction and how the built-up Flow affect Brand Equity. Therefore, the research model investigates what factors influence Flow. Furthermore, the research is designed to understand how the Flow influences Brand Equity. The antecedents of Flow classifies into three types such as personal (Challenge, Skill), IT characteristic, Internet Auction characteristic. The results of this empirical study shows that three characteristics significantly affected the flow：personal (Challenge), IT (information quality, system quality), and Internet Auction (interactivity). And also Flow has significant effect on the brand equity. This result indicates that customer's optimal experience is important to increase brand equity. That is, the flow is influenced by multi-dimensional factors and plays an important role in increasing brand equity. Finally, the finding of this study suggests that personal challenge, information quality, system quality, and interactivity should be enhanced preferentially.

This study was intended to identify the problem of the lien in relation to the real estate auction and present its improvements in terms of procedural laws. To resolve the problem of the lien in the real estate auction, it is valid that the Vollstreckungsgericht needs to set the certain standard in relation to the possession of real estate and notify it at the first date of sale by judging whether the lien can be established. And the institutional improvement is required to obligate one to report the lien in the procedures of the real estate auction and reinforce the survey of the present condition of the lien. And it is necessary to impose the more public confidence on the statement of sale by including the matter of the lien in it. In addition, it is necessary to reinforce legal punishment to the false and fictitious lienholder and establish the legal stability of the lien in the process of the real estate auction.
