인터넷이 발전하고 성장함에 따라 전자상거래(Electronic Commerce)는 초기의 단선적인 관계와 집중화된 구조를 탈피하여, 상호 연관적인 관계 및 분산되고 개방적인 구조를 바탕으로 수행되고 있다. 즉, 인터넷의 본질적인 특성인 네트워크를 기반으로 하는 시장구조가 형성되고 있으며, 이러한 네트워크 시장구조를 기반으로 하여, 새로운 형태의 비즈니스 모델이 출현하고 있다. 네트워크 효과(Network Effect)를 기반으로 하는 네트워킹 비즈니스 모델은 초기의 비즈니스 모델과는 다른 형태의 정보흐름(Information Process) 및 구조(Architecture)를 가지며, 이로 인해 전자시장(Electronic Market)에서 참여자의 역할 및 사업 전략, 수익모델 등이 변화되고 있다. 이 논문에서는 네트워킹 비즈니스 모델이 가지는 구조 및 특성을 규명하고, 사례분석을 통해 다양한 형태의 네트워킹 비즈니스 모델을 분류하여, 네트워킹 비즈니스 모델의 활용가능성을 모색해보고자 한다.

We present a matrix-based inference alorithm suitable for electronic commerce applications. For this purpose, an Extended AND-OR Graph (EAOG) was developed with the intention that fast inference process is enabled within the electronic commerce situations. The proposed EAOG inference mechanism has the following three characteristics. 1. Real-time inference: The EAOG inference mechanism is suitable for the real-time inference because its computational mechanism is based on matric computation.2. Matrix operation: All the subjective knowledge is delineated in a matrix form, so that inference process can proceed based on the matrix operation which is computationally efficient.3. Bi-directional inference: Traditional inference method of expert systems is based on either forward chaining or backward chaining which is mutually exclusive in terms of logical process and exclusive in terms of logical process and computational efficiency. However, the proposed EAOG inference mechanism is generically bi-directional without loss of both speed and efficiency. We have proved the validity of our approach with several propositions and an illustrative EC example.

The purpose of this study is to find out the effectiveness of Electronic Commerce through Agent. There have been many researches related to Electronic Commerce, the rate of changes and progress in information systems being too fast, most of them are outdated. Through the analysis, three factors are newly found to be important which are not studied in other researches. One is end-users’ technical environment and the other is the improvement of end-users’ abilities in business management, social consciousness as well.

Nowadays, the explosive evolvement of Internet. which is referred to as EC, has been prevailing. That has given the chance all of the world consumers to contact all of the world companies to enter into business relationship. But, electronic commerce laws have been established per conventional jurisdiction. some legal issues take place in the field of cross-border electronic commerce, including the governing law and competent courts. In this situations, it is gradually and widely required to lay down the internationally harmonized electronic commerce legal framework. Now, there are a lot of legal issues assumed in EC, in this study, we studied three precedence problems concerning B2C: Consumer Protection Law regarding B2C, Personal Information Protection Law in Private Sector regarding B2C, Web Site Trust Mark System.

The tremendous growth of the Internet, particularly World Wide Web, has bought significant changes in the economics of marketing channels and has led to a redefinition of industry value chain. While electronic commerce has become as an important issue with the growth of the Internet, there are insufficient empirical research efforts concerning its status in Korea. The study findings suggest that contextual problems need to be solved before electronic commerce provides real benefits for consumers and businesses. The suggestions and strategies are provided at both a firm level and a consumer level. The objective of this research investigates TQM's the key quality factors and Customer's Using Satisfaction of Internet shopping mall in Korea. In addition, we tried U find out what factors discourage consumers from using electronic purchasing methods, as well as how perceived quality factors and customer satisfaction when consumers are exposed to the purchase process on the Internet shopping mall business.

The Synchronized Multimedia Integration Language (SMIL) is a declarative markup language based on the eXtensible Markup Language (XML) to define a set of markup tags for synchronizing the timing and positioning relationships between multimedia objects. SMIL makes authoring of TV-like multimedia presentations on the Web easier for applications such as electronic commerce. We present the design and implementation of a JAVA-based SMIL player, which processes different types of media objects using multiple threads. Moreover, its cache engine detects the media type and allocates the proper cache memory for the corresponding media object.

This paper proposes the design and performance evaluation of a marine engine fault detection system using a proximity sensor for marine engine. Non-linearity is greatly reduced by using the sensor without increasing the response time by applying the CANopen protocol. The CANopen protocol enables the sensor to send initial values and measurement data. The marine engine fault detection system measures crankshaft deflection and the bottom dead center of the crosshead in real-time, which maintains stability and prevents the serious breakdown of the marine engine by use of an interlocking alarm monitoring system.

Information technologies have been wide spread in the public sector, especially government administrative of office. Most of the Korean internal government, IT influence focused on the hardware and input system, not so fast realized, and don't have fundamental development less of business dimension. And now, the electronic document implementation efficiently satisfies the government's process and management through the reduction of manned working steps. This study suggested the elimination of old ragged custom based on paper document. inner basis environment composing for the using of electronic document and the introduce of digitized network tele-working system etc, for the highly execution of future digital management system.

Recently, International electronic commerce has been rapidly increasing. Over the past decade, e-commerce on the business foundation of the Internet compound has entered extensive areas of international trade and social activity. This paper focuses on the system establishment of customs duties of import goods in Global e-Commerce. Today, USA, EU and some major countries, International Organization insisted to Tariff-free woe in customs duty. This study also will discuss the effect of imposition of import duties. In order to impose customs duties, it needs to establish a system scheme, especially, because international payment of BtoC Commerce occur by the Credit Card. This study deals with Customs duties of import goods in Global e-Commerce.
