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.

In this study, we investigated web contents accessibility of 60 hospital web sites in Korea. The eight evaluation criteria were used for estimating the web contents accessibility of the web sites. These criteria were as follows: providing an alternative text, providing caption for moving picture, providing a skip navigation, usage of pop-up windows, usage of a summary or a caption tag for data table, providing a page title, providing a label for online form, and usage of java scripts. K-WAH 3.0 was used for estimating five evaluation criteria. According to Internet web contents accessibility guideline 1.0, we estimated the rest three evaluation criteria manually and described good or bad examples for the evaluation results technically. The results show that the web accessibility of hospital web sites is generally insufficient and the constant interests in improvement for accessibility are urgently needed.

This research is carried out being divided into a first evaluation and second evaluation. A Study is carried out on first, the accessibility compliance level of Korea government department websites and second, whether the site which complies well with web accessibility increases web usability for users through a web usability evaluation. The evaluation result, web sites which comply well with the web accessibility guidelines were observed to increase web usability for both normal and disabled people but web sites which do not comply well were observed to lower the web usability making the web sites unavailable or inconvenient to use. Therefore, it can be concluded that there is a very close interrelationship between web accessibility and usability and thus compliance with web accessibility is not an option but a mandatory requirement.

Current web accessibility checks and automatic assessments have been pointed out that the assessment items and scores are evaluated from the developer's point of view rather than from the user's one. In addition, although most of the grades of an automatic assessment on the public web sites are excellent because they are built in accordance with the web accessibility development guidelines, not a few web sites shows relatively low grades in evaluating their usability test made by those users. Taking into account the inadequacy of these web accessibility assessments, this study has identified the differences between the grades of usability evaluations and automatic evaluations for people with low vision and analyzed the major factors affecting web accessibility usability evaluations using Repertory Grid Techniques. Also, the Hard Laddering method of the Means-End Chain theory was adopted to visualize the relationship between Attributes-Conferences-Value and a hierarchical value system analysis based on FGI(Focused Group Interview) to people with the low vision. This study proposed the measures to improve the current web accessibility automatic assessment allocation, expert evaluation criteria, and user task assessment. In particular, it is a web accessibility user evaluation model that can consider the web accessibility quality certification criteria and user review assessment by directly analyzing the user cognitive structure and value system. This study is expected to be useful as a research to enhance the quality of web accessibility assessment.

Museums have recently been expanding their roles as education providers to use websites to provide a variety of information and services including educational programs. In order to better perform their roles as education providers, it is important for museums to commit themselves to making their websites accessible and easy for everyone to use, in compliance with web accessibility. 20 of museum websites were chosen to study the state of web accessibility of domestic museum websites, and were evaluated by using an automated web accessibility evaluation tool called the K-WAH 4.4. And then, we analyze the compliance rates of web accessibility based on 6 Requirements in the KWCAG 2.1. As a Result, only two museums satisfy the compliance rates on 6 Requirements and national & public museums are higher than private museums in compliance rates. So, to improve web accessibility, we comply with accessibility guidelines and design web contents. After witch we should improve web accessibility by modifying insufficient requirements immediately through periodical evaluations.

The Web accessibility compliance rate of public organizations and private enterprises is still low due to the lack of awareness of Web accessibility by website developers and managers in spite of the fact that web accessibility compliance became mandatory in 2008. Web developers and managers think the website visual quality might be compromised or the website requires more development time and budget in order to comply with the web accessibility guidelines. Therefore, this paper has analyzed whether developers with various training in web accessibility or experience on website development have different perception on time, cost and design issues for developing accessible websites. For this purpose, 72 Web developers with hand-on experience working for website development companies in Korea were sent to the questionaries. The results have indicated that the group of developers with many hours of training in web accessibility and rich experience on website development perceives that they can develop accessible website without additional cost and time or compromising design quality. The contributions of this paper are following： (1) proving the widely recognized perception on budget, time, and design for developing accessible website is incorrect and (2) motivating further research on this subject in the future.

The importance of web accessibility becomes important due to a legal obligation to comply with web accessibility. However, there are few educational programs developed on web accessibility for vocational high schools in Korea. In this study, to explore the future possibilities of web accessibility curriculum the survey with information teachers of 97 vocational high schools was conducted along with review of the curriculums of the domestic and foreign web accessibility educational programs. The survey results indicate that (1) the information teachers have only basic conceptual understandings on web accessibility and (2) they have little intention on teaching web accessibility at their vocational high schools due to current educational conditions and the lack of web accessibility knowledge. The results of this study could be employed as references for the web and web accessibility educational courses at the vocational high schools.

The purpose of this paper is to find the method to improve the web accessibility of Korean Government's web sites through the investigation on the evaluation result of visually impaired people and the accessibility evaluation tool. Twenty five Korean Governments' web sites are chosen for this experiment. First, all of the sites are evaluated by accessibility evaluation tool (A-Prompt) based on Priority one of the Web Contents Accessibility Guidelines (WCAG) 1.0 of W3C. Second, three visually impaired people tried to find information or resister for the sites to check the accessibility. All of the sites are failed to conform to WCAG 1.0 and most of those are not accessible to information. The last part of this paper presents the method to improve the web accessibility of the Government's web sites.

In the study, we introduce the trend in domestic and foreign web accessibility, as well as the legal system that ensures web accessibility. Based on Korean Web Content Accessibility Guidelines (KWCAG)1.0, we investigated the web content accessibility of 80 tertiary health-care hospitals and general hospitals in Korea. We evaluated accessibility by combining accessibility-based criteria (ABC) with usability-based criteria (UBC). ABC was limited to an alternative text for Guideline 1, using a small number of frames and keyboard accessibility for Guideline 2. UBC checked the voice service (TTS), resizing text, providing multi-lingual websites, and disclosing web accessibility policy. KADO-WAH2.0 was used for representing the compliance rate. The evaluation result was a considerable improvement from previous results, even though the rate of compliance with web accessibility was generally insufficient. There was a significant difference between those medical centers which did and did not comply with web accessibility. Incidentally, many hospitals were found to have attempted to confront and come to terms with web accessibility. In future, the following factors are advisable for medical centers with publicity or public interest: they must employ active and aggressive promotion of establishment of independent accessibility guidelines to secure web accessibility, they should effect an improvement of the realization of web accessibility, there can be constant education and promotion, and there can be an institutional supplementation, as well as others.
