Online-ADR (Alternative Dispute Resolution) has been receiving attention from the international community as a means of alternative dispute resolution for consumer disputes in both small and mass international e-commerce. The EU Parliament and the Council proposed the Online Dispute Resolution Regulation for Consumer Disputes (hereafter, "EU Consumer ODR Regulation") and the Directive on Alternative Dispute Resolution of Consumer Disputes (hereafter, "EU Consumer ADR Directive") as a legislative package, now scheduled to be adopted. Those efforts strengthen consumer protection by enhancing ODR in international e-commerce and improving of the functions of the e-commerce market. The EU Consumer ADR and ODR regulation package will operate in conjunction with the ODR platform as a single point across Europe, abandoning the ADR system of each member. Consumers and traders who need dispute resolution apply on the EU ODR platform linked website, and the applications are distributed to individual ADR institutions in accordance with the Rules and Procedure of ADR institutions in the respective country. Although there has been partial progress in Korea for ODR programs such as the establishment of the Online Administrative Trial and the procedures of individual ADR agencies operating through the website, existing norms do not fully support the system. At this point, we see many implications of the EU Consumer ADR and ODR regulation package on the direction chosen for domestic ADR and ODR policy and legislation. This study introduces the main features and content of the EU Consumer ADR Directive (draft) and ODR Regulation provisions, and describes the direction of domestic policy and legislation regarding Online-ADR.

전자상거래에서 신뢰도는 전자상거래 서비스 제공업체의 비가시성이나 그들의 평판으로 인한 소비자의 우려를 완화시켜주기 때문에 사용자의 신뢰수준을 추정하는 것은 전자상거래의 지속적 사용에 있어 중요한 기술이다. 기존의 신뢰도 측정법은 주로 전자상거래 시스템에서 사용된 정책과 평판기반의 추론에 근거한 사용자들의 초기 경험에 중심을 두었다. 그러나, 보다 성숙된 단계의 전자상거래 시스템 지속사용 가능성 추정을 위한 신뢰도 측정에 대해서는 별다른 대안이 없었다. 따라서 본 연구에서는 성숙단계에서의 전자상거래 시스템에 알맞은 신뢰도 추론방법을 제안한다. 특히, 친밀도는 평판뿐 아니라 신뢰도와도 깊이 관계하고 있기 때문에 사용자의 입력을 강제하지 않는 친밀도 측정 방법을 새롭게 개발하였다. 성과 측정을 위한 실험에서는 제안된 방법이 유효하고, 평판기반의 신뢰도 추론과 함께 사용할 수 있는 것으로 나타났다.

In this research, an internet-based fabric information system has been developed. Recently, the numbers of textile industries which have their own homepages to advertise their product fabrics fur apparel through the Internet and textile e-Commerce web sites rapidly increase. Unfortunately, traditional fabric information systems based on direct meeting and trust cannot give sufficient information to numerous visitors of the Internet sites including fabric buyers for apparel. They can just view 3-dimensional fabric images and text-based specifications such as fabric density, composition, colors, weight, etc. To solve these problems, the new fabric information system fur apparel has been developed. The web-based fabric information system is composed of the following six modules; $\circled1$ fabric database management system, $\circled2$ a 3-D fabric drape image viewer to illustrate fabric appearances, $\circled3$ a virtual wearing system to apply a fabric to garment designs, $\circled4$ a fabric property viewer to confirm fabric characteristics, $\circled5$ a QC (quality control) document generator to manufacture high qualify garments with a fabric, and$\circled6$actual display mall to view actual fabrics. The fabric information system is simply performed by visitors clicking the buttons hyper-linked with JAVA applets on web browser. The web-based fabric information system enables the web site visitors to understand fabrics shown on the Internet in more details.

인터넷의 급속한 보급과 정보통신기술의 발달은 전자상거래의 확산을 가져 왔고, 그 결과로 전통적인 상거래에 기반을 둔 조세행정에 커다란 변화를 요구하고있다. 이에 따라 OECD국가를 중심으로 전자상거래의 확산이 조세분야에 미치게될 파급효과에 대한 연구가 활발히 진행되고 있다. 그 결과 EU 집행위원회에서는 전자상거래에 부가세를 도입하기로 하였으며 우리나라의 경우도 2-3년 후에는 전자상거래에 부가세가 도입될 전망이다. 그러나 미국은 2003년 말까지는 부가세의 도입을 금지하기로 결정한바 있다. 특히 소비지 과세원칙의 적용 문제, 재화와 용역의 구분, 대리납부제도 및 납세관리인제도 등의 도입 등이 논의되고있다. 이에 본 논문에서는 효과적인 전자상거래 부가세 도입을 위하여 우리나라의 부가세 기본구조와 전자상거래의 활성화가 조세행정에 미치는 영향을 살펴보고 이에 대한 대응방안에 대한 선진국 특히 OECD 국가들의 연구동향과 이를 토대로 우리나라의 대응방안에 대하여 살펴보고자 한다.

Recently, many organizations in various industries have introduced e-business for the purpose of adding value to their business. But, the e-business model has not existed before and so, it is difficult to analyze clear effectiveness. It frequently does not live up to an organization's expectations. It is due to an absence of environmental changes analysis in the new model, not by a new model itself. System Dynamics(SD) may provide effective results as a tool of analysis for the new model. This research shows the analysis of the effects of a simulated e channel model, which was expanded from existing channel modeling with actual data in basic materials industries. The results show average prices increasing by auction process on the e-market and an increase in sales. So, by increasing the speed of sale revolution stock expenses are reduced. Additionally, we applied a possible scenario to the developed simulation model and investigated strategic issues to draw desirable strategies with market changes.

In recommender systems which are used widely at e-commerce, collaborative filtering needs the information of user-ratings and neighbor user-ratings. These are an important value for recommendation in recommender systems. We investigate the in-formation of rating in NBCFA (neighbor Based Collaborative Filtering Algorithm), we suggest new algorithm that improve prediction accuracy of recommender system. After we analyze relations between two variable and Error Value (EV), we suggest new algorithm and apply it to fitted line. This fitted line uses Least Squares Method (LSM) in Exploratory Data Analysis (EDA). To compute the prediction value of new algorithm, the fitted line is applied to experimental data with fitted function. In order to confirm prediction accuracy of new algorithm, we applied new algorithm to increased sparsity data and total data. As a result of study, the prediction accuracy of recommender system in the new algorithm was more improved than current algorithm.
