This paper proposes structural analysis on the World Wide Web to form a part of the architectural design project. It purposes modeling space frames and a structural analysis program on the internet only by inputting basic data for forming a shape in the whole phase of space frame analysis. The analysis data is conducted by Oracle DBMS(DataBase Management System), GUI(Graphic User Internet) by Java Applet and connection with server and database by Java Servlet respectively. The result from modeling and analysis is provided as graphic and text file forms by web browsers. Programs can be executed irrespective of user's OS by using internet and highly-secured system is constructed taking advantage of Java. Of great efficiency is maintaining and recycling data as the whole is dealt by database from the beginning to the end of program.

Using the self-contained characteristics of XML, in various areas the XML is widely used to a meta language which can describe information and is recognized to a standard language to present information on the web. In this paper, we point out many difficult problems when we are going to a serial activity of software engineering like that we analyze, reuse, and maintenance source programs. Then we describe whether the existed studies about documentation provide the solutions for the problems above mentioned or not. Finally, we propose the JML(Java Markup Language) that can effectively support solutions about these difficulties. Then we analyze the sample program and present the generated JML docuement using the results. explain the result that The JML is an XML DTD to describe software information written by Java language. Also, we describe the meaning of elements that are parts of whole JML, and explain how to represent the information of Java source codes using each element.

인터넷의 발달로, 사이버 환경을 위한 C 프로그래밍 교육 컨텐츠가 많이 개발되고 있으나 적절한 실습 환경까지 제공되지 않고 있다. 그러나 프로그래밍 언어의 교육은 실습이 수반되지 않으면 그 효과가 상당히 떨어진다. 본 논문에서는 인터넷상에서 효과적으로 사용할 수 있는 C 프로그래밍의 실습환경을 구축한다. 특히, 학생들이 이해하기 어려운 함수 프로그램의 실행과정을 Java Applet을 사용하여 시각화 보여준다. 함수 프로그램 실행 시각화기가 설계되고, Java 환경에서 구현된다.

In this paper, a example of a development of web-based remote monitoring and control system using Java technology on TCP/IP is proposed. We implemented Client/Server socket programs using Java Socket class, and applied those to a greenhouse made from LEGO blocks and made web-based greenhouse remote monitoring and control system. Implemented System transferred states of greenhouse to client programs, and control signals from client program were transferred to Server. Greenhouse model was controlled well by the system.

객체지향 언어인 JAVA를 이용하여 Web-기반의 운동 해석 프로그램을 개발하였다. 지금까지 운동해석에 관한 대부분의 프로그램은 Fortran, C, C++ 와 같은 언어로 이루어져 있으며 이 경우 계산 속도는 빠르지만 각 언어의 Compiler 와 Builder를 필요로 한다. 따라서 사용된 각각의 언어에 대한 Compiler 및 Builder가 사용자의 개인용 컴퓨터 상에서만 설치 및 구동될 수 있으며 그로 인해 사용자는 계산된 Data형 결과물만을 얻을 수 있었다. 본 연구에서는 이를 개선하고자 객체지향형 언어인 JAVA를 이용하여 운동해석 프로그램을 구성할 수 있는 기반을 구축하였으며 Web과 연동하여 시간적 공간적 제약을 극복하고 사용자의 의견 개입을 가능하게 하였다. 일반적으로 JAVA 언어는 연산속도가 느려서 수치해석용으로는 부적합 하다는 평이 지배적 이였으나 컴퓨터의 성능 발달로 이는 개선이 될 수 있으며, 이는 사용자가 시간적 공간적 제약을 받지 않고 사용 가능하다는 점에서 극복되어 질 수 있다.

Since java thread is an object which is treated as independent process within one execution space in the multiprocessing environment, we can use it for independent process of parallel processing. Using thread and synchronization mechanism of java enables us to write parallel application program easily. Therefore, a lot of results are exist which is apply the feature of java that support parallel processing to the distributed computing environment. In this paper, we introduce a system of environment that support parallel execution of thread which is included in legacy java program. The system named TORB(Transparent Object Request Broker) enables us parallel execution of legacy java program after simple converting process, since it support the feature of programming transparency. TORB is extended version of distributed programming tool that is published by our research team. And it had only typical distributed processing feature that is execute a specified function at the specified computer.

Concurrent programs, which are composed of threads that can operate concurrently, are intrinsically nondeterministic. Therefore, we can not directly apply classical testing or debugging techniques developed for sequential programs to concurrent programs because of the nonreproducibility due to nondeterminism. In this paper, we present a source tranformation method to guarantee the reproducibility of multi-threaded programs written in Java programming language. Once a mutli-threaded program has been transformed according to the transformation rules, we can force the program's execution to follow the given sequence of synchronized methods repeatedly and reduce the efforts to find the source of the errors. In addition, we present a method for checking the feasibility of the synchronized method sequence to be replayed.
