It is difficult to find web contents for visual disabilities in spite of rapid growing internet users, infrastructures and advance of computer technology. For the case of usenet newsgroup concerning disabilities, hit rate is even less than E-mail because of lack of accessibility, educational support and economical expense for internet. This paper is addressed to voice usenet newsgroup service by using telephone or web browser for visual disabilities without additional S/W support such as 775, usenet program and installation program, suggests a design method and an implementation example for it. Main features of it are easiness of man machine interface, popularity of access device such as telephone or web browser and independency of particular news server by using NNTP. This system supports general MIME format, is implemented for usenet server of Korean Social Worker's Community and will be implemented for Gomduri InfoNet BBS of Korean Society for Rehabilitation of Persons with Disabilities.

무선인터넷 기술발달로 대용량의 웹사이트를 휴대전화에 전송하는 것이 가능해지고 디스플레이도 3 인치 이상의 WVGA 고해상도 제품이 출시되고 있으며 망개방 이라는 시대적 요구와 맞물리면서 모바일 풀브라우저가 주목 받고 있다. 그러나, 유선 인터넷 환경의 웹사이트를 좁은 휴대전화 화면에 그대로 구현하여 사용하기란 쉽지 않다. 따라서, 본 연구는 모바일 풀브라우저의 현황을 살펴보고 사용성 검증을 통해 현재 서비스 환경에 최적화된 모바일 풀브라우저 UI 제안을 목적으로 한다. 이를 위해 국내외 주요 이동통신사의 풀브라우저에 적용된 공통적인 기본 UI 요소를 검토하여 추출하였다. 그 후 사용자 조사를 통해 추출된 기본 UI 요소들을 비교해 보고 각 기능의 중요도 및 기능 별 최적안을 도출하였다. 마지막으로 사용자 조사를 통해 검증된 이슈를 기반으로 향후 모바일 풀브라우저 인터페이스를 제안한다. 본 연구는 여러 모바일 풀브라우저의 기능별 방식에 대하여 사용자의 실제 경험을 통해 검증함으로써 향후 모바일 풀브라우저 개발에 있어 사용성을 향상 시키는 자료로 활용 될 수 있을 것이다.

Life cycle product data is very important yet difficult to handle for manufacturing companies. Shoring and exchanging product data over world-wide-web is a part of key technology to implement PDM or CALS. STEP is widely accepted as a standard to represent the life-cycle product model data. Described in this paper is a web browser plug-in that can graphically display and explore product data represented by STEP over internet. By the use of the plug-in (named "npSTEP"), a product model data stored in STEP format on a web server can be displayed on a commonly used web client (browser), such as Netscape navigator, without any format conversion process. Furthermore one can explore the components or attributes of the product model data in hierarchical manner.

The development of technology provides and increases security as well as convenience for humans. The development of new technology directly affects the standard of life thanks to smart home automatic control systems. This paper describes a door control, automatic curtain, home security (CCTV, fire, gas, safe, etc.), home control (energy, light, ventilation, etc.) and web-based smart home automatic controller. It also describes the use of ARM (Advanced RISC Machines) for automatic control of home equipment, a Multi-Axes Servo Controller using FPGA (Field Programmable Gate Array) and PLC (programmable logic controller). Additionally, it describes the development of a HTML editor using web auto control software. The tab loading time (7 seconds) is faster when using ARM-based web browser software instead of Chrome and Firefox is used because the browser has a small memory footprint (300M). This system is realized by web auto controller language which controls and uses PLCs that are easier than existing devices. This smart home automatic control technology can control smart home equipment anywhere and anytime and provides a remote interface through mobile equipment.

This paper deals with self-tuning of fuzzy control systems. The fuzzy logic controller(FLC) has parameters that an: input and output scaling factors to effect control output. Tuning method is proposed for the scaling factor. In this paper. it is studied to control and to monitor the remote system statues using SOAP for communicate between the server part and the client part. The remote control system is controlled by using a web browser or a application program. The server part is waiting for the request of client part that uses internet network for communication each other and then the request is reached. the server part saves client data to the database and send a command set to the client part and then the client part sends command to controller in a cool chamber. The administrator can control and monitor the remote system just using a web browser. The effects of membership functions, defuzzification methods and scaling factors are investigated in the FLC system.

EDMS(Enterprise Document Management System) is generally as an office business management solutions in the form of an application running in a Web browser environment, has been utilized as an Electronic Document Management System. This system, users access the browser has led to inconvenience not easy. For for ease of use this, how to implement a system that can be used to operate the EDMS on the screen of the Windows Explorer, in this study, are presented.

This paper is about a system development which control and monitor a PLC of the remote-distance through the Internet using the web-browser. In general, the PLC uses its own communication protocol of PLC Manufacture. It is actually impossible to be used through the Internet, because the PLC communication protocol is basically developed to be suitable for short-distance. Therefore, what we need is a transformation system which can convert the PLC communication protocol into the form which can connect to the Internet. In that sense, this paper is that about remote-control method through the WWW ( World Wide Web ). This system have three characteristics. First, it is possible to connect the Internet directly irrespective of CPU, Operating system and browser. Second, it is easy for user to access and treat. Third, it needs only HTML to operate without java or plug-in expansion. In this paper, we will introduce the monitoring and control system of PLC on the Linux with the Apache web-server.

Mobile handhold devices such as PDA(Personal Digital Assistant) and Cellular Phone are more and more popular for personal web surfing. But today, most mobile handheld devices have relatively poor web browsing capability because of the small bandwidth of wireless connection, the small speed of CPU, the small capacity of RAM and Flash ROM, the small display size of LCD and the short lifecycle of battery. Users have to endure bigger communication latency than Desk PC's one because of these factors. In this paper, we propose an effective pre-refresh mechanism for handheld device's embedded web browser so as to make user's web surfing faster. The experiment was done using the simulator designed by ourselves and the experiment result demonstrates the proposed mechanism has a good performance to make web surfing faster.
