Increased competitive challenges are forcing companies to find better ways to bring their applications to market faster. Distributed development environments can help companies improve their time-to-market by enabling parallel activities. Although, such environments still have their limitations in real-time communication and real-time collaboration during the product development process. This paper describes a web-based collaborative framework which has been developed to support the decision making on a 3D design developing process. The paper describes 3D design file for the discussion that contains all relevant annotations on its surface and their visualization on the user interface for design changing. The framework includes a native CAD data converting module, 3D data based real-time communication module, revision control module for 3D data and some sub-modules such as data storage and data management. We also discuss some raised issues in the project and the steps underway to address them.

This paper analyzes techniques that extract objective information from distributed web databases for bioinformatics based on relationship among information. Moreover, we discuss the design and implementation of a method for knowledge enhancement in respect of protein information. Web data extractor can be constructed by using a manual, semi-automatic, or automatic way. Data extractor generally makes use of identifiers in order to search and extract targeting information from a specified web page. This paper presents a design and implementation for the protein databases of an organism by utilizing web data extraction techniques.

Due to significant advances in Internet technology, there have been many e-learning courses offered by universities and academic institutes nowadays through the Internet. And these courses have benefited many students who might be constrained by distance and time. Nevertheless, most web-based courses are lecturing courses that cannot fulfill the needs for engineering technology education. In this paper, we propose the design and implementation of web-based programmable logic controller(PLC) laboratory to support learning and training for industrial automation. The proposed web-based PLC laboratory system consists of virtual labs and remote labs. This web-based PLC laboratory can be accessed by registered students to practice PLC experiments at their own home, enhancing the quality of education without much increasing in the overall cost. With the help of web cameras, the students can even have experience the live PLC experiments through the Internet.

Recently, roost of the companies have, utilized internet with the purpose of business. According to this tendency, each company is exchanging various information and offering services of e-business through Web-Site. Contents on Web-Site are getting huge and the period of contents renewal is getting short. Consequently, each company is faced with many problems for the contents management because of specialization and fractionation of contents. A contents management system that creates, maintains and manages efficiently and conveniently contents on Web-Site toward solving these problems is very required. in this paper, we design and implement such a web contents management system. It also supports dynamic web page publication based on the XML components.

Recently, Linux operating system is used for web server environment, but to build web server applications need to be operated many related softwares, such as installing web server, web and database system integration and programming for script language. Most of schools in korea do not have computer specialist for building web server or cyber school. In this paper, we describe design and implementation of an automated building system(AnyBuilder) for cyber school. AnyBuilder build web-based cyber school system, just clicking a few of button and some commands. Especially, it has two phases to build cyber school, one is to generate empty web-based cyber school and the other is to upload contents of lecture.

최근 web기반에서 언제 어디서나 사용자만의 컴퓨터환경을 제공하는 Virtual OS를 구현한 사례가 많이 발표되고 있다. [1, 2, 3]. Virtual OS는 Unix나 Windows같은 Real OS를 기반으로 하여 web에서 OS의 기능을 구현한 것으로 Real OS에 있는 프로그램을 실행하고 파일을 관리한다. 본 논문에서는 Web기반 Virtual OS에서 동작하는 C 언어 Preprocessor를 설계한다. Web기반으로 preprocessor를 설계하면 어디서나 사용자가 프로그래밍을 할 수 있는 환경을 구축할 수 있다. 본 논문에서는 Linux를 기반으로 preprocessor를 구현하였으며, 분석 결과를 시뮬레이션을 통해 알아보았다.

The purpose of this paper is to introduce and propose the vision of information design for the user-friendliness and accessibility for web-based information services. Information design, which focuses more narrowly on the information itself in one or more information units, and may encompass the information aspects of elements of design(labels, knobs, and the physical interface), information content design, page design, Web site design, typography decisions, and so forth. Information design is an alternative to all traditional approaches to information (science, philosophy, and others). Information is designed according to consciously chosen principles and criteria. rather than by following habitual patterns of a traditional profession.

Using a web browser, real-time video communication technologies are emerging today. In this paper, we studied the web browser and take advantage of real-time video communication technology for Based on this, we have designed and implemented a Web-based real-time video communication systems. In this system, having different web browsers and web servers through a web browser using the RTC API and HTTP / WebSockets in a real-time video communication is possible. It is available at all terminals, all connected by a network environment from the use of the web browser, will be utilized in the field of visual communications in a limited environment.

The internet survey is more time and cost efficient than the off-line survey. We design and implement a web-based questionnaire generating system for the internet survey. The system guides users to make up a questionnaire step by step. It also generates data code for the statistical packages such as SPSS and SAS when the internet survey has been done.
