As the state of the art for handling multimedia on the internet is developed a new system called WebCAM which services video and image came out. However, WebMIC site for audio services are still rare. In this work, we developed a WebMIC system which enables anyone to listen audio in real-time through the internet. WebMIC system is implemented by connecting a server with a microphone and the recorded audio files are stored in a Database system. Because the microphones can be distributed sporadically, the developed system can be utilized for managing and advertizing a location. It also can be used to reduce the cost for the existing management system which is almost met by personnel expenses. Anyone who can connect to the internet can get this WebMIC service, so this system can produce a good effect if used in advertising any tourist resort.

For Web System composed of a variety of hardware, software and network system, there is a wide difference in price, function and capacity. In addition, it is important to select the most suitable system when web system is constructed as the claim of high-quality web service from user has increased. Data of bench-marking is usually employed when the system is selected. Evaluation with the result of bench-marking, however, is not easy at web situation composed of a variety of systems. In this paper, first integrated bench-marking of hardware, software and network system metric were determined, and the plan to effectively compare and evaluate the result of bench-marking by using fuzzy set were offered.

We have designed embedded web sewer system and ported Linux operating system version 2.4.5 at our system. And then We implemented to control and monitor widely separated hardware and implemented to monitor widely separated image using CMOS image sensor HV7131B. Web server is the Boa web server with General Public License. We designed for this system using of Intel's SA1110 ARM core base processor and connecting input and output device at GPIO port of SA1110. Device driver of General purpose I/O for Embedded Linux OS is designed. And then the application program controlling driver is implemented to use of common gate interface C language. User is available to control and monitor at client PC. This method have benefit to reduce the Expenditure of hardware design and development time against PC base system and have various and capacious application against firmware base system.

The purpose of this study is to implement web-based quality cost management system to measure the performance of quality improvement activities in the business firms. Developed WQCMS(Web-based Q-Cost Management System) have ability to collect and analyze quality data generated from various different departments in the inside or outside of the enterprise without any limitations, if end-users are able to access wide area network. It provides the capability to integrate quality information from database and to generate various easy analysis reports to management's needs using built-in analysis tool modules with real-time. The proposed system was developed using Microsoft's .Net technology, ASP.NET and MS-SQL Server 2000. By web-enabling Q-cost management system, the effectiveness of the system management and utilization was realized by easiness of information integration and economical efficiency.

국내 병원들은 u-Hospital 서비스 구현을 위한 진료예약시스템을 구축, 운영하고 있고, 운영되고 있는 시스템의 대부분은 웹 기반의 방식을 사용하고 있다. 최근 등장하고 있는 Web 2.0 기술은 웹 방식에 있어서 편리한 UI 구조 제공, 빠른 응답서비스 등의 장점을 가지고 웹 영역의 많은 부분을 변화시켜 나가고 있다. 이 기술은 웹 영역을 넘어 모바일 영역에서 일부 응용이 시도되고 있다. 본 논문에서는 Web 2.0 기술을 적용하여 모바일 진료예약 시스템을 구축하였다. 이 시스템은 기존의 모바일 및 웹 기술에 비해 적은 페이지 뷰와 빠른 로딩속도로 인해 사용자의 편리성 및 응답속도를 개선하였고 성능실험을 통해 이를 증명하였다.

웹 프락시 서버에서 디스크 I/O는 병목현상을 일으키는 주요 요소이다. 오늘날 대부분의 웹 프락시 서버는 범용 파일 시스템에서 실행되도록 설계되어 있다. 그러나 범용 파일 시스템은 웹 캐시 워크로드에서 대부분 차지하는 작은 파일들을 효과적으로 처리하지 못하기 때문에 전체 웹 프락시 서버의 성능을 저하시키게 한다. 본 논문에서는 범용 파일 시스템을 사용하지 않는 원시(raw) 디스크 I/O 기법이 웹 프락시 서버의 디스크 I/O 오버헤드 개선에 얼마나 영향을 미치는지 그 성능 잠재력을 평가한다. 이를 위해 웹 프락시 서버를 위한 저장관리 시스템인 BSMS(Block-structured Storage Management System)를 설계하고 Squid 소스에 적용시켜 웹 프락시 서버를 구현하였다. 다양한 실험 평가를 통해 원시 디스크 I/O 기법이 웹 프락시 서버에서 디스크 I/O의 성능을 크게 개선시키는 좋은 방법임을 보였다.

온라인 및 모바일의 발전에 힘입어 개인 혹은 기업의 홈페이지 및 웹 콘텐츠(Web-Contents)를 관리하기 위해 CMS(Contents Management System) 및 WCMS(Web Contents Management System)를 도입하는 사례가 꾸준히 증가하고 있다. 이에 따라, GUI(Grapic User Interface) 기반의 WCMS를 설계하고 좀더 간소한 절차로 콘텐츠를 수정하고 확인 할 수 있는 WCMS가 필요하다. 본 논문에서는 WCMS에 기반을 둔 웹 콘텐츠를 사용자 정의에 의해 재구성하여 GUI 기반으로 좀더 효율적이고 편리하게 수정 할 수 있도록 시스템을 설계하고 단순화한 로직을 구성하는 연구를 통하여 직관적이고 편리한 웹 콘텐츠 관리 방법에 대해 연구하였다. 따라서, 본 논문에서 제안하고 있는 WCMS 기반의 웹 콘텐츠 수정 및 편집시스템은 사용자로 하여금 기존의 웹 콘텐츠 수정 처리 시스템에 비해 속도 개선 및 사용의 편의성 등이 뛰어나 웹 콘텐츠 수정 및 편집방법으로 널리 활용될 것으로 사료된다.

The web-based groupware systems hold many possibilities for system developers and users. Especially, web-based group collaborative systems are emerging as enterprise-wide information systems. Since data in group collaborative systems are apt to be shared among multiple concurrent users and modified simutaneously by them, the web-based group collaborative systems must support synchronous collaboration in order to provide users with synchronized and consistent views of shared data. However, current web technologies have limitations in supporting this, largely because the existing Hypertext Transfer Protocol(HTTP) is unidirectional and does not allow web servers to send messages to their web browsers without first receiving requests from them. This paper proposes an active web server that can overcome such limitations and facilitate synchronous collaboration in web-based group collaborative systems. To accomplish such goals, the active web server manages dependency relationships beween shared data and web browsers referencing them and actively propagates changing details of the shared data to all web browsers referencing them. And, this paper examines usefulness and effectiveness of the active web server to apply it to the ball-bearing design example of concurrent engineering design systems. The prototype system of the active web server is developed on a commercial Object-oriented Database Management System(0DBMS) called OBJECTSTERE using the C++ programming language.

We are focusing on an approach which handle a general Web as a resource in order to support self-directed learning for a student. Then, we are developing a Web based learning environment "Web-Retracer"for utilizing Web as teaching materials by a user′s Annotation. Although the learner can share the Web resource that the others utilized in this environment, Web resources unsuitable for a student′s needs becomes hindrance about her/his self-directed learning. In this paper, we propose a recommending method of the resource united with a student′s needs on the basis of a student′s learning and Web browsing history. This method analyzed the feature peculiar to a resource, and extracts the resource with which the needs of the feature and a student agreed.
