This paper's objective is to provide insights about the problems and expansion strategies of electronic trade. Korean small and medium-sized firms have adopted the Internet since the end of 1990s in order to reshape their competitiveness, and it is now being utilized as a major export marketing instrument to develop new customers, save export transaction costs ad facilitate new work processes. However, at present, the use of the internet in the field of trading is limited to the collection of market information, owing to legal, technical and institutional restraints between countries. In addition to that, because firms have the difficulties in making the trade contract through the e-trade system, the negative recognition on its' utility has been spreaded gradually between companies. This is one of the barriers to block the expansion of e-Trade between Korean firms. Therefore, this paper points out the problems of e-trade in the environmental, institutional and strategic view and provides many considerations for establishing the expansion strategy of e-trade by the Korean government and trade supporting institutions.

인터넷은 단순히 통신수단의 변화에 그치지 않고 문화 사회 정치의 각 방면에서 커다란 변혁을 불러일으키고 있으며, 물품매매계약이 전자적으로 이루어지는 경우 전자상거래계약의 성립시기, 방식 및 전자문서의 효력, 준거법(applicable law, governing law), 재판관할(jurisdiction)등에 관하여 복잡 다양한 문제점들을 야기하게 된다. 전자상거래 계약상에서 청약의 기준에 관해서는 매도인의 행위를 청약으로 보는 것이 다수설이다. 따라서 매수인이 선돼한 상품에 대하여 구입의사를 표시, 즉 승낙하면 바로 전자상거래 계약이 성립한다고 할 수 있다. 그리고 인터넷을 이용한 전자상거래의 경우에는 국경을 초월하여 세계의 모든 소비자들을 그 대상으로 함으로써 준거법의 문제와 재판관할권의 문제가 상당히 중요한 문제로 부각되고 있는 바, 준거법의 결정은 일반적으로 당사자의 자유로운 의사에 따라 결정된다. 재판관할권에 대해서는 재판관할에 대한 합의가 있는 경우에 우려 나라는 이를 유효한 것으로 인정하고 있으나, 일반 소비자들을 대상으로 하고 있는 전자상거래의 특성을 고려할 때 이는 다소 무리가 따른다고 생각된다. 또한 재판관할에 대한 합의가 없는 경우에는 피고의 주소지국이 재판관할권을 부여받는바, 격지자간의 소액거래에서는 그 실익을 기대할 수 없는 것이 현실이다.

The Rotterdam Rules regulate both transport documents and the legal effect of the choice of document much more comprehensively than the existing maritime convention to bring international harmonization of issues relating to transport documents. The Rotterdam Rules use the generic term 'transport documents' rather than referring to specific title such as bills of lading, sea waybills. The generic term 'transport documents' allow four types of transport documents to be identified as follows. 1. negotiable 2. negotiable which dispense with surrender 3. non-negotiable which require surrender 4. non-negotiable. Each types of transport documents has its requirements to be satisfied. Also, the choice of transport documents affects legal effect. Thus parties to the contract of carriage not only need to know how the document will be classified at the time it is issued but also consider what the documents will bring legal consequences.

In an electricity market, the spot market is normally integrated with a forward or future market. The advantage of the forward market is to allow the market participants to deal in a part or the whole trading portfolio at a fix price in advance and to avoid risk associated to the uncertain price of the spot market. Japan has introduced a continuous auction base forward market from April 2005. This paper analyzes the Japanese forward market rules and operations, and introduces a new algorithm that may improve the efficiency of the market itself. The proposed algorithm enables us to give consideration to the specific characteristics of the power system and to integrate them in the auction mechanism. The benefits of the proposed algorithm are verified on an electronic simulation platform and the results described in this paper.

본 논문에서는 이산대수 문제에 거한 새로운 1-out-of-n 비대화형 불확정 전송 암호화 프로토콜을 제안하고, 다자간의 공평한 비밀정보 교환방식을 새로이 제안하였으며 이들방식을 이용하여 Flat-Shamir 서명방식에 근거한 새로운 디지탈 다중서명방식을 제안하고 안전성을 분석하였다. 제안된 디지탈 다중서명방식은 동시성, 실행 가능성 및 부정 조기검출성을 가지고 있으며 다수의 사람이 참여하는 전자계약 서명시스템에 적용될 수 있다.

In this paper we propose a fair and secure e-commerce model for P2P network, in which communication entities can buy and sell products by P2P contract. In particular, we focus on a fair transaction protocol that is based on a collaboration with distributed communication entities. This feature makes our model very attractive in P2P networking environment which does not depend on any central trusted authority for managing communication entities.

The rapid expansion of regionalism has resulted in the creation of blocs of the global economy, so that those countries not belonging to one or more blocs can be discrimiated. Though signed on the bill of FTA with Chile, Korea is actually alienated from major stream of the blocs. Therefore, Korea government makes efforts to contract more FTAs with countries such as Singapore and Japan, others. FTA is believed to be an important method to secure export and national competitiveness. Therefore, we need to exactly understand critical issues and the long-run effort of FTA. This paper tries to find out important issues and potential strategies relating to electronic commerce in Korea's FTA with other countries. In these means, relationship between FTA and e-Trade are closely related to global business chance. In these means, we should use FTA potentials for encouraging global commerce by e-Trade and develop e-FTA in the foreseeable future.

전자 정부의 시스템들은 공신력 있는 데이터를 보장하고 그 정보의 위·변조를 막아왔으며, 지금까지 이러한 역할을 전통적인 중앙집중형 관리 방식으로 진행되어 왔다. 하지만, 중앙 집중형의 데이터 관리 방식은 단일 오류점의 문제와 병목현상의 단점을 가지고 있다. 이러한 문제를 해결하기 위해 블록체인 기술이 등장하여 그동안 안전하지 못하다고 생각되어 왔던 탈중앙화를 특징으로 하여 데이터의 무결성을 보장한다. 하지만, 일반적인 블록체인과 스마트 컨트랙트를 전자 정부의 전자투표에 그대로 적용하기에는 많은 문제점들이 존재한다. 본 연구에서는 전자투표에 무결성과 자동화 기능을 제공하기 위해 블록체인과 스마트 컨트랙트를 적용하여 투표 데이터의 무결성을 보장하고 투표와 개표의 과정들을 스마트 컨트랙트로 자동화하는 방법을 제시하고자 한다.
