본 논문에서는 취약성 탐지 스크립트의 원격 편집기를 설계 및 구현하였다. 원격 편집기는 Windows 계열의 시스템에서 구동되며 스크립트 데이터베이스가 저장되어 있는 서버로부터 스크립트를 인출하여 수정 후 저장하거나 새로운 스크립트를 작성하여 저장한다. 편집기는 스크립트의 작성 및 편집을 위한 편집기능, 서버와의 HTTP 프로토콜 기반 통신 기능, 스크립트의 사용 용도나 스크립트의 경향과 특성을 파악하는 등의 특성분석기능, 스크립트의 유효성 및 문법 검사기능을 가지고 있으며, 원격 편집기의 요청이 있을 때에 이에 응답하기 위하여 스크립트 데이터베이스 서버측에서 CGI(Comman Gateway Interface)가 구동된다.

본 논문은 대학교의 학생들을 위하여 학과 교과서를 저렴한 가격에 구입할 수 있는 가상 중고서점을 Apache+Php+MySql을 활용하여 구축함으로써 기존 Perl CGI(Common Gateway Interface)방식 보다 빠르고 안전한 웹서비스 할 수 있고, 다른 한편으로는 선 후배간 되물림을 토대로 친목 도모를 할 수 있다. 대학 중고서점은 역 경매 방식으로 설계되었으며, 일반 중고서점 쇼핑몰과는 달리 대학 교과서를 중심으로 매매가 형성되며, 책을 모아둘 창고가 별도로 필요치 않아 소자본으로도 창업이 가능하다. 제목별, 지은이별 검색은 물론, 학교별 분류, 학과별 분류를 제공하여 교과서를 검색하기 때문에 누구든 빠르고 쉽게 교재를 검색하고 찾을 수 있도록 구현 하였다.

Embedded system is used a lot in electric home appliances and home network equipment. However, this system is designed to operate by the system operator directly at home and operator could find out them only when he pays attention to the system in case event happens. In this paper, to improve above things, it designed to remote-control system anywhere in which internet access is possible as well as at home, and also it designed SMS(short message service) information transmission system to inform the errors to the operator when they happen. To design the system, development board(be included the Strong Arm), CDMA module, and electric door lock are used as hardware, and web browser, CGI(common gateway interface) programming, and C-language are used for implementation of software in embedded-linux platform.

본 논문에서는 구매자의 수에 의해 가격이 결정되는 공동구매형태의 경매 형태를 제안한다. 제안한 경매 형태에서의 입찰자가 입찰 금액을 제시하여 적절한 낙찰자를 구별하는 형태의 일반적인 경매 형태가 아닌 입찰한 수에 의해 판매자가 제시한 가격 곡선에 의해 낙찰 금액이 정해지는 형태이다. 이러한 형태는 기존의 판매자와 관계가 1:1의 일반적인 경매 형태가 아닌 판매자와 구매자의 관계가 1:n 또는 n:n의 형태가 된다. 본 논문에서는 이러한 공동구매 형태의 경매 형태를 에이전트 기법을 이용해 시스템을 구성하였으며, 각각의 에이전트는 Perl을 이용해 CGI(Common Gateway Interface)로 구현하였다.

웹의 등장은 인터넷 인구의 엄청난 성장을 가져왔다. 이와 더불어 최근에는 가상 금융 및 전자 상거래 시장등을 지원하는 웹 상의 데이터베이스 관련 상품들이 속속 등장하고 있다. 이에 기존의 데이터베이스 시스템과 클라이언트-서버 방식으로 동작하던 응용 프로그램들은 웹 환경에 적합한 상호 연동방식을 요구한다. 본 논문에서는 관계형 DBMS인 SRP를 웹상에서 동작시키기 위한 통로인 SWeS를 제시한다. SWes는 CGI를 이용한 응용서버 방식으로 구현하였으며, 동적 서버 교체와 페이지 단위의 결과 전송 기법등을 사용해 가용성 및 동시성,확장성을 높이는 구조를 갖는다.

This paper deals with an integrated system that facilitates researchers to do motif and domain search effectively and systematically. The system we developed is constructed on the basis of the integration of various resources related to motif, domain, and protein family. Those resources that can be classified into databases and search programs are dispersed to be available in Internet. In order to develop this system, we extracted core contents of diverse databases, which are required to analyze the protein function in terms of motifs or domains, to construct local databases and installed motif or domain search programs on our server, which corresponding database has as its own search program. Diverse utilities and CGI (Common Gateway Interface) programs make the databases and the search programs interlocked and web-based graphical user interfaces integrate all the components of our system. Employing our integrated system, end-users can receive its one-stop service to do protein function analysis systematically and effectively, without surfing many sites in Internet and wasting time over integrating search results.

In this paper, we implemented a real-time remote home monitoring system which we have ported the Linux OS and HTTP(Hypertext Transfer Protocol) web server. The GoAhead web server was ported using by ARM cross compiler. And then we used the analog to digital converter ADC0809 for sensing the vii able input signal at widely separated home. We have implemented linux device driver for ADC(Analog to Digital Convertor) and CGI-C(Common Gateway Interface - C language) application program using Client pull method for monitoring real-time changing data. The factor of monitoring is temperature, intensity of illumination and gas's existence. And this system has ability which check the status of out door and gas valve. We have designed the embedded web server system for home emergency monitoring in low cost.

The paper is a design and implementation of the Hybrid Messaging System as integrating electronic mail system and common mail system based on PKI(Public Key Infrastructure), A user writes mail through Web Browser and sends the mail to Web Server. CGHCommon Gateway Interface) program sends the mail that was received through the Web Sever to Post Office Electronic Mail Server using SMTP(SimpleMail Transfer Protocol), The End Process program of the Hybrid Messaging System in a Post Office fetches the mail from the Post Office Electronic Mail Server using POP3 (Post Office Protocol 3), prints it and deliver it to recipients, Also, the Hybrid Messaging System is able to sign the mail with a sign private key that the Certificate Authority publics for users and encrypts the mail with a public key of the Post Office Web Server.

We implement the PBSM (Protocol-Based Security Module) system which guarantees the secure data transmission under web circumstances. There are two modules to implement for the PBSM architecture. One is Web Server Security Module (WSSM) which is working on a web server, the other is the Winsock Client Security Module (WSCSM) which is working on a client. The WSCSM security module decrypts the encrypted HTML document that is received from the security web server The decrypted HTML document is displayed on the screen of a client. The WSSM module contains the encryption part for HTML file and the decryption part for CGI (Common Gateway Interface). We also implement the proposed idea at the web system.

In recent years, as remotly-sensed image processing technologies have been improved and spread widely in the application areas, many new requirements for the image processing technologies have arisen. However, it is difficult and costly to access remotely-sensed image processing systems. Moreover, these systems have thier own processing facilities which are not easily accessible for general users. In this paper, those problems are challenged by adopting Internet as a universal information network for accessing remotly-sensed image DBMS and by allowing users to work remotely on the image processing. A remotly-sensed image processing system which can be accessed via Internet was designed and implemented. This system can be used to manipulate images over remote DBMS. The Illustra object-oriented relational DBMS with CGI(Common Gateway Interface) web interface was used in this project. The client consists of a WWW(World Wide Web) Netscap$e^{TM}$ browser, and the server consists of HTTPD(Web daemon), Illustra DBMS and Java modules in order to process the image being displayed. The developed system was tested on LAN environment and the service response time met the requirements.
