Deleting unsolicited email, popularly known as spam mail, is an annoying task for Internet users. Moreover, spam mail causes a variety of social problems. At present, legal restrictions cannot eradicate spam senders. As a result many technical methods to eliminate spam mail such as spam filtering and online stamps have been introduced. However, the process of blocking spam mail can inadvertently result in suspension of indispensable or beneficial communication. In this paper, we propose a certificate and agent based emailing architecture that can block spam mail, while at the same time approve certified mail. This architecture can be accelerated by synergistic utilization of digital signature and electronic document interchange.

There are gradually built on electronic commerce and business information system for the effective and automated use of internet while the mainstream of industry moves on information. It is necessary that a company should develop a electronic approval system because the business documents have application to an electronic commerce, business information system as well Currently, electronic approval system on groupware is using the way of inserting the image of an approval signature, which is vulnerable on a security by attacks of fraudulent use of electrical signature and eavesdropping on electronic documents. In this paper, we implementation XML form generator based on DTD having business documents structure for creating a valid business XML documents. we designed electronic approval system based on secured XML which transfers encrypted documents. For the security issues of written XML business documents, it makes use of the crypto algorithm having high performance transaction by the interchange of public key between a server and a client.

The area of business applications in the internet are extended enormously in result of fast development of computing and communication technologies, increase of internet use, and use of intranet/extranet in enterprise information system. Widely spread the use of the internet, there are various applications for Business to Business (B to B) or Business to Customer(B to C) model that are based on the intranet or extranet. This paper designed and implemented the Web-based Electronic Bidding System for Business to Business (B to B) model. The technical issues of electronic bidding system in the internet are involved in the connection between web client and server, electronic data interchange for the contract document, and security solution during the bidding and contracting processes. The web-based electronic bidding system in this paper is implemented using Java applet and servlet as a connection interface for web client and sewer, XML/EDI-based documents for a bid and a contract, and bidding server and notary server for enhancing the security using PKI(Public Key Infrastructure)-based public key cryptography, digital signature and Certification Authority (CA).

The International Chamber of Commerce introduced in September 1999 its new publication Incoterms 2000(ICC Publication No 560). The ICC was building on the past experiences in its revision works. I have discussed and commented constructively some main features and problems of the new set of terms. Incoterms 2000 takes into account, like already its predecessor did, the possibility that the parties may decide to communicate electronically and replace a paper transport document by an equivalent electronic data interchange message. This possibility will certainly be much more used under the present set of terms. Incoterms 2000 is well recognised by the international legal community, taking into account also the endorsements by UNCITRAL to its predecessor in the early 90's. Incoterms 2000 does not have major competitors remaining. However, the ICC still faces a battle to convince more traders to refer to its terms and to teach traders to understand and to apply them correctly. Incoterms 2000 is a tool for international trade created by a global business organisation. Its members decide every day if and to what extent they make use of this tool. The members of the ICC have participated actively in the drafting and commenting of Incoterms 2000 and thereby shown again a great deal of dynamism in creating rules for their own everyday use. Under these circumstances, "ship's rail approach" related to delivery point, risks and costs should be replaced by "on board approach" under FOB, CFR and CIF terms.

국내 제약산업의 경쟁력을 제고시키기 위해서는 신약의 심사/허가 기간을 단축시켜 급변하게 변하는 글로벌 제약시장에서 경쟁 우위적 위치를 선점할 수 있도록 기회를 제공할 수 있도록 체계 개선이 시급하다. 신약허가를 위해서는 임상시험 결과에 대한 안전성과 유효성 등에 대한 심사가 수행되게 된다. 하지만 현재 신약허가를 위해서 제약사와 임상시험수탁기관(Contract Research Organization, CRO)에서 데이터 정보체계인 Domain, Variable 및 Parameter 등의 표준을 따르지 않고 다양한 유형의 임상정보데이터를 심사기관에 제출하고 있어 이로 인한 심사기간 증가와 심사업무 비효율성을 야기시키고 있다. 따라서 본 연구에서는 국제민간기구인 CDISC (Clinical Data Interchange Standards Consortium)에서 제정한 글로벌 임상데이터 표준인 CDISC 표준을 준용한 국내 임상시험정보관리 체계 (eCTD 시스템)및 의약품 전주기적 관리체계를 제시하고자 하며, 본 연구를 통한 기대효과로는 국제표준의 임상정보관리 인프라 구축으로 인한 국내 신약개발 및 해외 진출 환경을 마련하여 글로벌 시장선점의 기회를 제공할 수 있고, 규제기관 차원에서는 의약품 허가, 심사업무의 효율성 증가는 물론 전주기적 의약품 안전관리체계를 마련할 수 있을 것으로 사료된다.

Costs and times, resources was better decreased than former times because it had been introduced EDI(Electronic Data Interchange) system. Nevertheless, many problems has been raised as before, that is high costs and data re-using, the rapidly changing environment, etc. To solve these problems, it was attempted to introduce XML technology at traditional EDI System. From this point to view, 1 designed and implemented XML/EDI System based on Internet(Internet Messaging System) in this paper. And I selected some services as basic service among many services which is provided at XML/EDI System, that is message sending and message receiving, message retrieval. Other service of client system was composed of MapIn and MapOut module. MapIn Module is to parse the received XML Message and to store XML Data to RDB system. And MapOut module is to generate XML Message after extracting data from RDB system and to transfer XML Message to recipient. Hereby, XML/EDI System(XEDI System) provide document re-using, the various result(output) generation f3r various requirement and directly interface with DB. Therefore, This System(XEDI System) is more various and more flexible than the existing Messaging System that just provide transfer and retrieval service
