Universal accessibility of web sites Is critical in a highly interconnected world. The web site should be usable by anyone, regardless of Individual capabilities and disabilities. But in reality, the users with disabilities are discriminated by inaccessible wed sites. This research analyze the accessibility of major web sites of Korea based on World Wide Web Consortium's Web Content Accessibility Guideline 1.0. The result shows that the average number of accessibility errors per web site is 2.77 much higher than that of Unites States. Automated testing and manual testing of web accessibility provides complementary results.

This paper reviews how to access the ergonomic information through internet-the world-wide computer networks. Recently, with the growth of hypertext type Internet-the WWW (World-Wide Web), it becomes much easier to access to the Internet and we can retrieve information very effeciently. In order to search the ergonomic information, this paper also reviews the famous Web search engines like Lycos, Web Crawler, and meta-indices like YAHOO. Also, useful Web-sites of ergonomics/human factors such as ErgoWeb are summarised.

Global climate change becomes one of the most serious environmental problems over the world. There is growing recognition thai climate change education, especially for children is important. However, there have been few programmes, curricula, teachers' training chances, and teaching-learning materials for climate change education so far. Therefore, we analyse the world wide web(web) contents in Korea which are available for climate change education, providing fundamental data in developing educational contents for climate change, as well as helping users to search appropriate contents for climate change education. Subjects for this study are 10 web sites of public institutions related to climate change in Korea. The web contents are evaluated in terms of diversity, accuracy, authenticity and the ease of use. The key finding in this study is that the majority of the contents are focused on how to respond to the problem, especially mitigation and also we find that most of the web sites provide text-types of lesson plan and video-types. Consequently, it would be necessary to develop various web contents for climate change education in both quality and quantity aspects.

The structure of a Web site can prevent the search robots or crawling agents from confusion in the midst of huge forest of the Web pages. We formalize the view on the World Wide Web and generalize it as a hierarchy of Web objects such as the Web as a set of Web sites, and a Web site as a directed graph with Web nodes and Web edges. Our approach results in the optimal hierarchical structure that can maximize the weight, tf-idf (term frequency and inverse document frequency), that is one of the most widely accepted content centric measures in the information retrieval community, so that the measure can be used to embody the semantics of search query. The experimental results represent that the optimization model is an effective alternative in the dynamically changing Web environment by replacing conventional heuristic approaches.

A hyperlink on academic World Wide Web has started to be recognized as a form of collaborative communication network connecting individual researchers and research groups and expanding their collaboration relations by making possible easy and direct online contact among people or groups anywhere in the world. This paper describes the structure of academic hyperlinks embedded in universities' Web sites hosted at the 10 Asian countries and further, examines the association between the structure of the hyperlink network and collaborative communication pattern among those countries based on their frequency of co-authoring articles. This research found that the number of inter-hyperlinks among universities' Web sites was significantly correlated with the frequency of co-authored articles across the 10 countries.

The continuous growth in the use of the World Wide Web is creating the data with very large scale and different types. Analyzing such data can help to determine the life time value of users, evaluate the effectiveness of web sites, and design marketing strategies and services. In this paper, we propose some analysis methods for web data and present an example of a prototypical web data analysis.

In this paper, we present a real-time remote patient monitoring service through world-wide web, which allows the medical doctor to monitor his patients in remote sites using popular web browsers. The real-time service consists of two services: Patient Locator Service (PLS) and Vital Sign Monitoring Service (VSMS). The PLS provides the information of patients currently being monitored. The VSMS allows the user to observe a stream of vital sign data of a specific patient. The vital sign data include ECG, respiration, temperature, $SPO_2$, invasive blood pressure and non-invasive blood pressure.

This study aims to apply World Wide Web(WWW) image files to visual material in lectures. Especially handles "Aesthetics of Landscape Architecture." Visual Materials of 800 web sites were searched and analyzed. It is found that web search needs a subject oriented web guide. It says now a need of application web material to lectures. Matching the web images with the subjects of lecture, above all, is the main approach of this study. Thus, a list up method is supposed, series of web image data to be inclusive in two tables. The data distribute on sub-subject, and applicant as materials in picturing objects of slide show, web guide, and single image. Two cases of lecture subjects were chosen in this study. A case that needs various visual materials and other case of advanced materials that needs a special web guide. Chance of results of this study is not yet fully clear in real lecture. It is sure, as an article of cyber lecture that provided result of increasingly participant's interest. By this study, it will be possible a fully made lecture material by further study.her study.

Since the World-Wide Web (WWW) has become a major channel for information delivery, information overload also has become a serious problem to the Internet users. Therefore, effective information searching is critical to the success of Internet services. We present an integrated search engine for searching relevant web pages on the WWW in a certain Internet domain. It supports a local search on the web sites. The spider obtains all of the web pages from the web sites through web links. It operates autonomously without any human supervision. We developed state transition diagram to control navigation and analyze link structure of each web site. We have implemented an integrated local search engine and it shows that a higher satisfaction is obtained. From the user evaluation, we also find that higher precision is obtained.

This paper introduces a simulation design decision support system to support the development process of the pipeline network and provide decision support to the operations of the gas pipelines. The system has been implemented on Flash5, which has a multimedia capabilities environment for designing and delivering low- bandwidth animations, presentations, and web sites. It also offers scripting capabilities and server-side connectivity fur creating applications and web interfaces. Hence a user can interact with the system on the World Wide Web.
