As the computer-based electronic processing of financial transactions become more and more popular in financial areas, the need for more efficient and secure infrastructure has been increased. This Paper addresses the current status and Policy issues in building such infrastructure for electronic financial transactions in Korea. We examine our financial computer networks, electronic payment and clearing systems, standardization, and related laws, comparing with those in United States, Japan, and European countries and suggest policy recommendation in each area.

스마트카드는 전자지불시스템에서 인증 수단으로 유용하게 사용되는 도구로, 스마트카드 개발시 이의기능이 올바로 동작하는지 테스트해 보는 것은 중요한 의미를 갖는다. 본 논문에서는 스마트카드의 기능을 테스트하기 위한 기존 연구 내용을 ISO/IEC표준 문서 및 KS 표준 문서 그리고 한국도로공사 카드 품질시험인증서를 기반으로 살펴보고, 한국도로공사의 하이패스플러스 카드에 대한 기능 시험 결과를 제시한다. 하이패스플러스 카드에 시험 평가를 수행함으로써 안정적인 기능성과 보안성을 가진 카드 시스템을 확보할 수 있고 나아가 신뢰성 있는 보안 제품의 개발에 기여하리라 기대된다. 본 논문에서 제시하는 시험 방법과 결과는 시범서비스 중인 스마트카드에 대하여는 국내에서는 최초로 수행된 연구로, 향후 좀더 보완된 시험 방안에 대한 연구의 기반을 제공하리라 기대된다.

This paper is a study on the model that measures economic values for the non-market properties of e-Business. For development of this model, first of all, we reviewed the properties of e-Business service, and looked around the relation between customer satisfaction and/or payment value and e-Business properties. In addition, we checked the method to measure economic values of these properties. This measurement method is the contingent valuation method which is a method of measuring the value of the environmental product. We modified it to adapt to the e-Business. Finally, in this paper, we proposed an economic value model which measures the value of willingness to pay(WTP) to our objectives. However, there could be some restrictions at the time when surveying empirically. Therefore, the succeeding study should be done in order to improve these restrictions some day.

본 논문에서는 웹브라우저를 이용하여 로봇을 원격 제어한다. 4대의 독립된 PC를 사용하여 각각의 기능을 분리하고 상호 연동하는 구조로 PC를 연결하였다. 조작자가 시간과 장소에 제약받지 않고 웹 브라우저를 이용하여 제어값을 입력하면 제어값은 웹 서버를 거쳐 데이터베이스에 저장된다. 로봇과 연결된 PC는 데이터베이스에서 1ms 간격으로 제어값을 입력받아 제어값의 변화가 있을 경우만 제어값의 변화량으로 로봇이 동작한다. 스텝모터를 이용하여 간단한 로봇을 제작하고 이를 웹 브라우저를 이용하여 실제 동작시킨다. 조작자가 원하는 제어값이 최종 수신단의 로봇에 제대로 전달되어 동작하는지 확인하고 웹브라우저를 이용한 로봇제어의 가능성을 확인하였다.

SWIFT has designed Trade Services Utility(TSU) to meet the new paradigm of electronic trade. The Trade Services Utility is a matching and workflow application that sits on the SWIFT network. The TSU is designed to help banks offer advanced supply chain services to their corporate customers who are involved in open account trading. Nowadays, the Bank payment obligation(BPO) can optionally be included in a baseline by mutual consent. The BPO is an irrevocable and conditional obligation of an obligor bank(buyers bank) to pay a specified amount to seller's bank according to an established baseline of a single TSU transaction. Therefore, SWIFT enables its customers to automate and standardise financial transactions, thereby lowering costs, reducing operational risk and eliminating inefficiencies from their operations. Whereas, Banks can use the core functionality of the Trade Services Utility to offer competitive services that complement existing services. But SWIFT need to come up with the measures of activating the TSU BPO. So, this paper is to introduce TSU BPO and check the measures for the activation of the TSU BPO under the electronic trade environment.

In this paper, we propose the coordination scheme in a single-manufacturer-multiple-retailer supply chain system. Traditionally, the bargaining power of the single manufacturer is superior to those of retailers. The business environment supported by the e-business scheme may give rise to new business behavior. The multitude of retailer requests the manufacturer to relax the his unilateral lot-sizing policy while they are willing to compensate more than the manufacturer's expected loss caused by abandon his superior bargaining power. The side payment aggregated by the multiple retailers is transferred to the manufacturer according to the degree of the manufacturer's relaxation from the current unilateral lot-sizing policy.

This paper presents an approach to solve the long-term generation expansion planning problem of the restructured electricity industry using an agent-based environment. The proposed model simulates the generation investment decisions taken by a particular agent (i.e. a generating company) in a market environment taking into account its competitors’ strategic investment. The investment decision of a particular company is modeled taking into account that such company has imperfect foresight on the future system development hence electricity prices. The delay in the construction of new plants is also explicitly modeled, in order to compute accurately the yearly revenues of each agent. On top of a conventional energy market, several capacity incentive mechanisms including capacity payment and capacity market are simulated, so as to assess their impact on the investment promotion for generation expansion. Results provide insight on the investment cycles as well as dynamic system behavior of long-term generation expansion planning in a competitive electricity industry.

Electronic commerce has been threatening to address the transaction inefficiencies in international trade that is conducted through letters of credit(L/Cs) and other forms of traditional paper-based financial instruments. The replacement of traditional paper documets with electronic alternatives is becoming more of a relity within a number of business sectors. The conceptual model of electronic L/Cs presented in this paper is intended to provide a framework for discussing the development of a paperless credit. The TradeCard network provides a business-to-business e-commerce infrastructure that enables buyers and sellers to conduct and settle international trade transactions securely over the Internet. Sellers and Buyers should select the best payment methods of traditional L/Cs, electronic L/Cs, TradeCard, Bank Credit Card etc. in consideration of their business circumstances.

This research examines 13 Korean Web sites and 15 foreign Web Sites to explore how companies present apparel products by both layout of graphics and information at the Web sites. The results show that most Web sites display tiny icons next to the item's text description. Clicking on these icons takes the customers to another web page, where the full size photograph of the item appears. The results also revealed that most web sites offer shopping bag function and payment options such as on-line and credit cards. The results indicate that Web sites are constantly evolving and following functions such as virtual dressing room, FAQ, the links, E-Cash payment, currency converter and multilingual sites are becoming standards in the near future.

This research investigates the rising new role of mileage system as private e-money in a exploratory study. The key research questions are "How does mileage system evolve with expansion of e-business and what are the cases for real experiences in 'money-like' mileage and their implications?" This research focuses on the proposition that mileage points created in commercial transactions as a royalty program are observed to serve a new role as payment tool. In an attempt to identify factors that determine mileage system as private money, we employ three factors: confidence, transaction cost, and monetary freedom. Also, this research proposes a direction for further research and follow-up studies to establish legal and institutional issues and the relevant architecture, all of which are essential elements to make the mileage points global money with a certain trade ratio in the near future.
