In this paper, we implement the speech recognition system based on the continuous distribution HMM and Browser-embedded model using the Java. That is developed for the speech analysis, processing and recognition on the Web. Client sends server through the socket to the speech informations that extracting of end-point detection, MFCC, energy and delta coefficients using the Java Applet. The sewer consists of the HMM recognizer and trained DB which recognizes the speech and display the recognized text back to the client. Because of speech recognition system using the java is high error rate, the platform is independent of system on the network. But the meaning of implemented system is merged into multi-media parts and shows new information and communication service possibility in the future.

The VMSS(Virtual Makeup Simulation System) is a virtual simulation system which can apply makeup, hair style, accessory to user's own face image through internee connection. The simulation result can be stored to server side DB and also can be printed out on client side printer. It is implemented using Java so, clients don't need any other client program to run the VMSS except Web browser and Java Plug-in installed on browser. IIS (Internet Information Server) Web server of Window 2000 and MS-SQL 7 are used to develop the overall system. Commercial JDBC Driver Type 4 is used to connect the applet and DB. It suggests a new direction of Web-based contents service development and can be applied to many other areas.

In this paper, a web based remote control system located at too dangerous field to access for the worker. The system was designed and implemented for three-dimensional stereo camera connected to web server which can be controlled easily by client side person working in the safe monitoring room. The user in the client side can control the vergence/focus control and zoom-in/out and pan/tilt functions through an user interface. The user interface for remote control environment was designed and implemented with Java applet mechanism, and was tested the operation result of the system.

The present study introduces some useful methods of implementing the Internet numerical analysis program with existing numerical codes for utilizing the Internet environment. The Internet gives developers good environment for development and release. Several methods were suggested, and some of them were implemented with an existing numerical code named SOLA-VOF, a computational fluid dynamics program to solve two-dimensional transient flow problems with free surface. This was reconstructed with Java technologies and compared with the original one. Java technologies have been applied to development of Internet applications for a long time. The objective of this work is to contrive methods of implementing Internet numerical analysis program with existing numerical codes and confirm the possibility of them. Methods using the applet-servlet communication were suggested and implemented. In addition, the Java web services with XML was introduced, which makes possible the cooperation of components. Although the concept has been suggested and developed for business applications, it can also be used for engineering softwares. Therefore, this study will be a preparation for numerical analysis to participate in engineering web services.

This paper presents an implementation of an Remote Examination System on Internet using Java and SWING GUI API. The system is consisted of three parts: generating examination part that is Java application, answering questions part that is Java Applet, reviewing results part that is Java Applet. The first part is implemented with the 2-tier client/server architecture and the last two parts is implemented the 3-tier client/server architecture. Database programming is done using Java JDBC API for database independence and portability. This system can be used the evaluation of lectures, and substituted for pen-and-pencil examinations or adopted to survey applications based on Internet.

Since simple and convenient user interface, the Web is diffused widely. For integrating Web as a view of user interface and CORBA, CORBA object is made in applet, which is sent to Web browser in Client and executes by Web browser. To use CORBA Event Service in Web without violating a security constrains of applet, we need a interoperability of Event Service. This paper investigates interoperability of event channels of the event service of CORBA. We present three different methods that make one event channel. Pros and cons of each method are described. All mentioned approaches have been implemented in Java. An experimental performance evaluation has been carried out and evaluation results are also given.

The purpose of this study is to develop the AM/FM system for a university using internet GIS. Because the developed system has an additional Java Applet functions, web user can execute dynamic data processing including static HTML GUI. The developed internet AM/FM system could be used for effective management work exact search and inquiry of both graphic information and attribute information rapidly. Also, it has the functions of mapping, attribute and spatial information searching, spatial query processing, etc.. Besides, this system could be used for realtime facility in any place or office using internet.

In this paper, we have designed a Home Networking System using an embedded linux board. The system based on the World-Wide-Web is composed of three parts - a Server, a Client and a Simulator. The Home Networking Server is built in an embedded board using an embedded linux kernel. A web-server and Home Networking Server Seryice Demon programming with a Jaya-Language is included in the board. Clients can connect to the server board using a web-browser in the desktop computer, PDA or any other machines which include a web-browser. For this purpose, we made the client program using a Java-Applet. So, the clients who connect to the server for the control of the applications, download the class-file and execute the client-program in the web-browser. So, the clients don't need any other programs to control the applications from a remote place. The size of server board is very small (86.3$\times$74mm), which makes it very useful not only for the Home-Networking-System but also in many other fields, e.g., embedded robot control system, etc. Using an embedded board instead of a desktop computer is good for a simple network environment and it occupies only a small space to make the system.

HTTP의 등장으로 전세계적으로 인터넷붐이 조성되고 있는 가운데 플랫폼과 독립적으로 실행되고 동적 문맥을 제공하는 자바 기술이 등장하였다. 본 논문에서는 이러한 변화에 따라 웹에서 사용가능한 케이스 서버의 필요성을 제시하였고 웹과 자바 기술을 사용하여 이 케이스 서버에 장착할 수 있는 이벤트 다이어그래머 애플릿을 설계하고 구현하였다. 이벤트 다이어그래머는 케이스 도구를 구성하는 여러 부품중 하나이다. 즉, 이벤트 다이어그래머는 이벤트와 작용의 관계를 표현하는 그래픽 표현 요소들로 구성된 표기법인 이벤트 다이어그램을 작성하는 도구이다. 이 논문에서는 작성한 이벤트 다이어그래머 애플릿은 웹에서 Martin/Odell의 객체지향 방법론에 따르는 이벤트 다이어그램을 작성해 주는 도구이다.
