We present the development of a remote observation system runnig on world wide web (WWW). The system consists of a 30cm Schmidt Cassegrain telescope and ST-7 CCD camera. We built the controllers and drivers of the telescope and the control softwares including the network control. The self-developed techniques in the hard wares and softwares can be applied to other projects in Korea. Observers can access the system via WWW home page, to reserve observation times, to send control commands, to retrieve images and various information useful for observation. This system can be widely used by students and amateur astronomers as well as professional astronomers who need a lot of small telescope time.

WWW(World Wide Web)의 발전은 인터넷의 대중화에 크게 기여를 했다. WWW은 쉬운 사용자 인터페이스와 다양한 멀티미디어 정보의 제공, 통일된 그래픽 사용자 인터페이스, 그리고 전세계 어디에서라도 손쉽게 접근할 수 있는 장점을 가지고 있다. WWW이 점차 발전하면서 인터넷을 통한 대용량의 멀티미디어 데이터의 처리가 필요하게 되었다. 이러한 변화에 따라 대용량의 데이터를 저장, 관리, 검색할 수 있는 데이터베이스 시스템과 WWW을 연결한 것이 WWW 데이터베이스이다. 본 논문에서는 기존에 서면으로 제출되어 심사되고 HARD COPY 형태로 보관되어 오던 논문심사 관리 과정을 개선하기 위해 WWW 데이터베이스를 사용한 논문심사 관리 시스템을 개발한다. WWW 데이터베이스를 사용함으로써 기존의 방법에서 발생되던 논문의 우편 전송 시간의 지연문제, 논문심사 시간의 지연문제, HARD COPY 논문 관리의 한계 등을 해결하였다. 본 논문에서 제시한 논문 심사 관리 시스템을 사용함으로써 학회 회원은 WWW을 이용해서 논문을 논문심사 관리 시스템 서버로 제출할 수 있다. 논문심사 과정의 내역이 데이터베이스에 저장되기 때문에 논문 제출자는 WWW을 이용해서 논문심사 결과를 조회할 수 있다.

In this paper, we introduce the concept of web-based simulation and some reviews on the distributed simulation on the World Wide Web (WWW) and classify the features of current web-based simulation under the distributed way. And then we suggest the structure of distributed web-based simulation which can achieve parallel simulation and reduce simulation run time and show how the callback mechanism works to enable the distributions of jobs to clients with push service in Remote Method Invocation (RMI). Finally we present a prototype of distributed web-based simulation.

Since the World-Wide Web (WWW) has become a major channel for information delivery, information overload also has become a serious problem to the Internet users. Therefore, effective information searching is critical to the success of Internet services. We present an integrated search engine for searching relevant web pages on the WWW in a certain Internet domain. It supports a local search on the web sites. The spider obtains all of the web pages from the web sites through web links. It operates autonomously without any human supervision. We developed state transition diagram to control navigation and analyze link structure of each web site. We have implemented an integrated local search engine and it shows that a higher satisfaction is obtained. From the user evaluation, we also find that higher precision is obtained.

In recent years, Internet/Intranet represents the next generation of computing environment. Therefore, it is necessary to integrate WWW((World Wide Web) over internet/intranet and DBMS(Database Management System) in proportion to the increase of various users' request and an amount of data variety. Also, also full variety of service over WWW need to accomplish rapidly modification of bug and make a betterment of system according to a feature of rapid change of information and an importance of interaction with users. The typical CGI method commonly used to connect with database has a disadvantage in time and resources in system due to frequent connection with database. Therefore, this paper provides the conceptual structure and implementation of information management system over WWW with applying a recent information technology called ASP(Active Server Pages) that controls and arranges client logic dynamically in server-side and introducing a concept of working group and folder to database design.

WWW(World Wide Web)은 인터넷상에 광범위하게 분산된 다양한 형식의 데이터를 손쉽게 검색할 수 있도록 하며, 모든 응용의 사용자 환경을 손쉽게 포함시킴으로써 새로운 미디어 타입의 통합을 위한 가장 성공적인 기술로 평가받고 있다. 처음 Tim Berners-Lee에 의해 처음 개발될 당시 WWW는 텍스트 기반의 구조에 맞추어 비동기적인 형태의 검색과 상호작용을 지원하도록 설계되었다. 반면 최근 인터넷상의 상당수를 차지하는 오디오, 비디오와 같은 실시간 환경의 멀티미디어 데이터들은 연속적, 동기적이며, 대화형 특징을 포함하고 있어 WWW에서 이러한 미디어들을 통합하기 위해서는 구조적인 확장이 요구된다. 본 논문에서는 현재 가장 많이 쓰이는 WWW 기능인 e-Mail 서비스에 대한 동기적 방법론을 제안하고자 한다. e-Mail 사용자가 HTML tag에 대한 사전 지식이 없이도 사전을 기반으로 e-Mail의 형식을 지정할 수 있도록 하며 이렇게 함으로써 보다 동기적인 형태의 서비스를 구현하도록 한다.

In this paper, the aims are to develop convenient and safe system-solutions, looking for missing-child, which is one of the increasing social problems, on the basis of World Wide Web. Finger-print cognition has been researching from long time before, as well as Bio-cognition technology, which is adapted for private-cognition in the field of human-cognition. By the fingerprint cognition, which discern finger print, which is generally used in Bio-cognition and is characterized each by using image-processing, missing-child protection system on the basis of Word Wide Web is designed and implemented in this paper. Additionally, indicates plans for revitalization method of this system.

A Remote Monitoring Server(RMS) server which uses Internet and World Wide Web is constructed for SMD in-line system. Hardware base consists of server computer, virtual SMD in-line system and other computers. Software includes assignment of server, RDBMS and various modules in server home page. Web browser provide production quantity, bad PCB quantity, error number and error message in virtual SMD module, user information in setup module, detailed error information in fault diagnosis module, fault history in fault history module and customer information in customer service management module. These functions of the RMS helps a decrease of non-operation time and a service response as fast as possible.

As internet use is being generalized central of WWW(World Wide Web) service of multimedia based recently, we could acquire many informations that exist to all over the world's computer network .Therefore, picking up of information became important problem before that internet is generalized, but it is risen to important problem to acquire correct information rapidly on modem society that use of internet is generalized. This paper designed internet search engine and understand structure of internet search engine drawing URL that is optimized, and secure embodiment technology using Java that is language of object base. Search engine that proposed in this paper maintained user's the convenience by offer keyword search, and simplify user interface And although quantity of searched information site is few, search engine show that the bad link rate of searched result is improved compare with existent domestic manufacture search engines.

Many features of the Single Field version have been enhanced to provide user friendly interface. The County/Watershed version of NAPRA WWW system was further enhanced. The newly developed Web GIS version is an ideal tool for novice users, such as farmers, to simulate the effects of agricultural management for their farms because of its easy-to-use Web GIS interface. The NAPRA WWW system provides an easy to use WWW interface and uses spatial and relational databases to simplify the process of preparing model files. Thus, the NAPRA WWW systems now can be effectively used for nutrient management as well as pesticide management to identify the least impact agricultural management practices.
