This study investigates the impact of website contents on Internet auction success. Based on the marketing concepts of stimuli, consumer behavior, and product involvement, the research model presents the theoretical relationships between the key factors of website contents and Internet auction performance. This study examines particularly four dimensions of website contents including transaction features, auction-specific features, seller's reputation, and information quality, which are deemed to have significant impact on the Internet auction performance, Each dimension of website contents is hypothesized to have a unique impact on a bidder's decision-making, which may vary depending on the bidder's level of involvement in the product. While transaction and auction-specific features serve as necessary components for successful auctions, a seller's reputation and information quality, as parts of satisfactory requirements, acutely affect bidders' decisions, especially those with high involvement to buy the product through a particular auction site. The outcomes of the analysis, in general, support the proposed model. The study results also provide meaningful Implications on ways in which auction websites can be improved for both sellers and auction service providers.

With the spread of electronic commerce, Internet auction systems have become widely used, because they overcome the spatial and the temporal limitations of traditional auction systems. However, most of current Internet auction systems have many shortcomings such as support for limited auction types, difficulty in registering items, maintenance problems, etc. This paper designs and implements a component-based seller-driven Internet auction system, which complements those traditional auction systems as follows: It allows sellers to select one of the auction types they want by answering questions which eventually lead to a specific auction type; Since it implements five basic auction types according to the principles of component-based development, it is easy to implement diverse types of auction systems with a slight modification to existing components. Further, the use of DAO concept makes it easy to use various commercial database systems.

The purpose of this study was to find the characteristics of internet auction user groups by the levels of addictive tendencies among high school students. The questionnaire was conducted from December 16 to 23, 2008, and 288 high school students who were living in Cheongju area were selected. The main results were as follows. First, 13.4% of respondents were visiting internet site almost every day, and about 20% of them stayed more than 2 hours for visiting the internet auction site. Second, the price of purchasing goods through internet auction site(shopping mall) was less than 50,000 won. Third, the level of addictive tendencies of respondents was under average(2.08 out of 5 point scale), and about 10% of them evaluated by themselves as an internet auction. Fourth, relatively higher addictive tendencies group showed the characteristics such as lower self-esteem, higher depression, and higher feeling of isolation, internet related(general internet use, internet shopping, and internet game) addictive tendencies, and more often visiting and staying longer in internet auction sites and other internet sites.

구매 물량이 많고 구매 시점이 분산되어 있는 기업간 구매경매에서 경매빈도와 한번 경매 시 거래되는 거래규모에 대한 결정은 구매경매 성과에 중요한 영향을 미치는 것으로 조사되었다. 하지만 이제까지 구매경매 연구에서는 새로운 시스템을 만들거나, 참여자들의 행위 분석 위주의 연구가 이루어지고, 경매빈도와 거래규모의 영향에 대한 실증적 연구는 없었다. 본 연구에서는 MRO 구매대행 업체의 실제 경매 데이터를 이용하여 경매빈도와 거래규모가 경매의 성과에 미치는 영향을 분석하였다. 분석결과 같은 대하여 경매빈도가 낮을수록 입찰자들이 경매시장에 대한 사전 정보가 부족하고, 상대적으로 적은 판매기회를 잡기 위해 낮은 가격으로 입찰하여 낙찰가격이 낮아지는 것으로 분석되었다. 거래규모는 가설과 달리 거래규모가 증가하여도 낙찰가격이 낮아지지 않았다. 대상 제품인 MRO 제품이 표준화되어 대량 생산되는 제품이므로 규모의 경제에 의한 가격 할인이 이미 반영된 것으로 파악되고, 특정 경매에서 거래규모의 크기가 추가적인 가격인하에 미치는 영향이 없고 오히려 거래규모가 적을 때, 상대적 낙찰가격이 더 낮아지는 것으로 분석되었다.

인터넷이 보다 대중화되면서 웹을 통한 다양한 서비스가 창출되고 있다. 경매분야도 예외는 아니어서 현재 국내외의 여러 사이트에서 인터넷 경매가 활발하게 진행중이다. 그러나, 대부분의 인터넷 경매시스템은 보안기능이 취약해서 사용자에게 큰 피해를 초래할 수 있다. 본 논문에서는 사용자에게 보다 안전하면서 편리한 인터넷 경매 환경을 제공하기 위한 안전한 인터넷 경매시스템을 설계하였다.

Since the advance of WWW, internet related fields have been growing very rapidly. Especially, the development of electronic commerce ares have changed even or life style. This paper is about the design and implementation of an internet auction system, which is considered as on of the most attractive internet services. An internet auction system has more complex processes compared with other electronic commerce systems. In auction systems, bids and a successful bid are required in trading all goods. In this paper, I designed and implemented all processes of an internet auction system, in which a bid tracing systems is included for the first time. The bid tracing system is implemented using only HTTP in maintain compatibility in WWW environment. I also used th JAVA blocking concept to simulate two-way communication. The proposed system is implemented on Windows NT environment using JAVA, ASP, and the Oracle database.

최근 전자상거래에서 지능적인 소프트웨어 에이전트를 이용하여 사용자에게 더욱 능률적이고 효과적인 경매시스템으로 발전시키고자 하는 연구 및 개발이 주목을 받고 있다. 단순한 게시판 형식의 인터넷 경매 시스템에 인공지능 에이전트를 도입하여 해당 경매 상품에 대해 판매자에게 적정한 경매 시기와 초기값을 계산하고 예측하여 최대한의 이익을 남길 수 있도록 해주는 에이전트 시스템에 대한 연구가 본 논문의 목적이다. 상품을 인터넷 경매에 올리는 판매자가 판매하고자 하는 경매 상품에 대한 정보를 인터넷 경매 시스템의 에이전트에게 메일로 보내면 에이전트는 해당 상품과 유사한 상품에 대하여 필터링하여 이미 학습되고 있는 유사 상품에 대한 정보 즉, 데이터베이스에 저장되어 있는 경매상품에 대한 입찰 히스토리로부터 경매시간, 경매방법, 낙찰가격 등을 계산한다. 본 논문은 이를 통하여 해당 상품에 대하여 판매자가 어느 시기에 얼마의 초기 가격으로 경매를 시작하면 최대한의 이익을 남길 수 있는지에 대한 정보를 메일로 푸쉬하여 주는 시스템을 제안한다.

Most Internet auction studies have focused on examining the determinants of auction success or closing price. However, there has been little previous research which investigates dark-side factors such as overbidding behavior in the Internet C2C transactions. For this reason, this study attempts to find situations with the escalation of commitment to bids using Internet auction systems and also examines whether the bidder's bidding is irrational. Therefore, this study applies escalation of commitment to explain the auction process such as the "going, going, gone period" with competition in Internet C2C auctions. In order to describe the auction process in terms of escalation of commitment, this study proposes psychological sunk costs, completion effect, and self-justification as the key factors of escalation of commitment and also willingness to continue bidding reflecting the decision maker's escalation behavior in terms of persistence perspective as final dependent variable. The results of PLS analysis indicate that a bidder's overbidding behavior is explained by the escalation of commitment.

The explosive growth of the internet-based transactions requires not only a secure payment system but also an appropriate trust measuring methodology and secure transaction protocols to guarantee the minimal risk for the transacting entities involved in specific transactions. Especially, in internet auction systems where either buyers or sellers or both can be more than one in one transaction, providing those systems that make sure no one transacting entity takes a major risk becomes critical. In this paper, an improved trust measuring method using a relationship-based internet community for an auction system is proposed. The proposed system incorporates fuzzy set and calculation concepts to help build trust matrices and models, which is used to measure the level of risk involved in a specific auction trade concerned. Also, to optimize the auction trade process in terms of cost and time, the proposed system recommends a differentiated trade protocol according to the risk level involved in each auction trade. To test the appropriateness of the proposed trusted auction system, a prototype system has been developed under a Windows-NT environment.

Existing internet auction systems have adopted the form which gives a win to the auction bidder who proposes the top bid price for the goods posted on the auction board. But they haven't been satisfying the automatical one-step processing for user's convenience because they must require continuous care of user for bidding and checking as well as neglecting the convenience of user interface while participating in the electronic bidding system. The AuctionBot system of Michigan Univ. is known as the representative internet auction system. It has merit allowing the various kids of bidding. But it does not support automatic a process which can replaces what user has to do using an agent. To improve this kind of user interface, we propose an automatic bidding price strategy algorithm which composes the auction system using agent and design for auto-bidding system using agent so that I can replace user's bidding activity. This mechanism gives an auction system the efficient bidding price strategy.
