Proportion and importance of knowledge & information provision through the web are increased continuously. Equivalent accessibility focused on universal service is highly demanded especially for public institutions, such as national libraries. In this study, web accessibility of sixteen national libraries were compared and analyzed by KADO-WAH, web accessibility tool. Characteristics of libraries were investigated and future directions were suggested based on the analysis and results.

웹은 제작과 사용이 간편하다는 이점으로 인해 사용인구가 폭발적으로 증가하고 있다. 또한 웹은 지역, 성별, 연령에 관계없이 사용할 수 있는 보편적인 특성을 지니고 있다. 이러한 웹의 보편적 특징은 특히 장애인들을 위해서 웹 접근성이라는 용어로 사용되고 있다. 이러한 웹 접근성을 평가하기 위해 국내 정부기관 웹 사이트와 국제기구 웹 사이트를 비교 평가하였다. 특히, 웹 접근성평가는 평가자의 기준에 의해 평가결과가 모호하며 평가결과가 상당부분 왜곡되어 있다는 문제점이 있다. 또한 이러한 문제점은 데이터테이블에서 두드러지게 나타난다. 본 연구에서는 데이터 테이블의 왜곡된 평가에 대한 문제점을 도출하고 그러한 문제점을 수정하여 국내외 웹 사이트들을 비교 평가하였다. 평가결과, 국내외 웹 사이트의 데이터 테이블에 대한 웹 접근성은 많은 격차가 존재하였으며, 웹 접근성 준수 여부는 지침의 기술적 준수뿐만 아니라 웹 사이트 설계 시 화면 구성에 의해서도 결정되어 짐을 제시하였다.

Web-accessibility evaluation tools can be used to determine whether or not a website meets accessibility guidelines. As such, many such tools have been developed for web accessibility, but most of them dynamically fetch and analyze pages and as a result, some pages maybe omitted due to the lack of access authorization or environment information. In this paper, we propose a static method that analyzes web accessibility via abstract parsing. Our abstract parsing technique understands syntactic and semantic program structures that dynamically generate web pages according to external inputs and parameters. The static method performs its analysis without omitting any pages because it covers all execution paths. We performed an experiment with a PHP-based website to demonstrate how our tool discovers more accessibility errors than a dynamic page accessibility analysis tool.

A website should be developed by considering web accessibility for being possible to access the Internet without any difficulties through the Web. In order to do this, after evaluating web accessibility with targeted 15 web sites based on KWCAG 1.0 which is a guideline of Korean type web contents accessibility and WCAG 2.0 which is a guideline of W3C's web serviceability by using KADO-WAH 2.0, this paper suggests improvements of web accessibility after deriving problems of web accessibility according to a web site type.

인터넷 및 IT 기술의 획기적인 발전으로 인해 우리가 접하는 정보는 그 양적 측면 뿐만 아니라 질적 측면에서도 비약적인 발전을 가지고 왔다. 또한 인터넷 보급의 활성화로 대부분의 사람들은 많은 종류의 정보 속에서 그리고 다양한 형식으로 구성된 정보 속에서 지내고 있다. 특히 웹의 사용이 일상화 되어감에 따라 컴퓨터를 다루기 힘든 정보소외계층의 웹사이트 정보 접근성에 대한 관심이 증가하고 있으며 그와 관련한 다각적인 연구도 활발히 진행 중이다. 본 연구에서는 선행된 웹 사이트 접근성에 관한 연구와 한국형 자동화 접근성 평가도구의 분석을 통하여 기존의 웹 접근성 평가의 한계를 파악하고 이를 통해 새로운 유형의 웹사이트 접근성 평가모형을 제안하고자 한다. 이를 위한 접근성 평가의 효율성 및 타당성 확보를 위해 먼저 자동화 평가도구인 Kado-Wah 를 이용하여 기본 평가를 진행하였고, 그 결과를 바탕으로 웹 페이지 소스분석 및 음성합성 S/W 를 통한 메뉴얼 평가를 실시하였다. 평가결과를 바탕으로 접근성 오류정도를 산출하여 한국과 미국의 교육기관 웹사이트의 접근성을 비교 분석하고 그 결과를 통해 향후 웹 기반 정보접근에 대한 효율성을 최대화 할 수 있도록 웹 구현에 대한 지침을 제안하고자 한다.

This paper shows trends in domestic and foreign web accessibility. To disclose the web accessibility observance rate, seven central adminstration institutions and another seven north-eastern cities in Gyeong gi-Do and seven major IT companies were evaluated. KADO-WAH 2.0 was used for showing the observance rate. The evaluation criteria was that of Internet Web contents accessibility Guidelines 1.0. The evaluation was limited to Guideline 1 and Guideline 2 of non-text contents and the restricted frame usage and the keyboard-only operation. The average points for three items are as follows: 65.56% for North-Eastern cities in Gyeong gi-Do and 43.71% for Central adminstration institutions and the average 29.33% for major IT companies. The observance rate was highest by 99.3% in Human-rights committee among the central administration institutions. With the observance rate of 98%, Namyang-ju city came first in Gyeong gi-Do area. Samsung electronics was the highest with 63.66% in observance rate. The Central adminstration got lowered from the average 82.14% in 2006 to the average 54.28% in 2009, with the result of 27.86% down. Accordingly, the urgent improvement for Central adminstration and Local adminstration in web accessibility is asked for. The same is true with major IT companies in web accessibility.

The purpose of this study was to identify Web accessibility issues of healthcare websites of the Korean government and public agencies by evaluating these websites' accessibility in accordance with the Korean Web Contents Accessibility Guideline. This study conducted both automated and expert testing to assess the accessibility of a total of 27 health-related websites. The results of the assessment which was conducted in two stages indicated that institutions such as the National Hospital and National Rehabilitation Center demonstrated almost no Web accessibility error. In addition, the Korea Health Insurance Review and Assessment Service, the Ministry of Health and Welfare, the Health Services Agency, the Ministry of Food and Drug Safety, and the Korea Medical Dispute Mediation and Arbitration Agency attained very high web accessibility. However, the results of an expert evaluation highlighted that there were considerable errors in providing appropriate alternative text, which was not found in the automated test, and the color contrast of the text content did not comply with Web accessibility standard. Therefore, these websites did not support web accessibility for the sight-impaired. Furthermore, the present study found that it was difficult to deliver accurate information to users due to errors in the default language display and markup, and also, issues of skipping repeated content, content linearization, and compliance with keyboard use were considered as challenges that might arise for people with sight, cognitive and mobility impairments with respect to Web accessibility. It is the first study that evaluated accessibility of healthcare websites of the Korean government and public agencies based on the Korean Web Contents Accessibility Guideline. The present study made a contribution to research on Web accessibility by conducting expert testing, which provided a more complete assessment that identified the degree and specific issues of accessibility errors when compared to automated testing.

This study makes an evaluation whether compliance on the web accessibility of domestic broadcasters site is observed to some degree. The compliance rate is estimated by six guidelines provided in KWA-H 4.0 automatically assessed tool. While the compliance rate of the broadcaster web accessibility is the highest in 'open new window' by 80.2% among six guidelines, the item of 'markup error prevention' demonstrated the lowest level by 36.2%.

Considering international trends and foreign cases, it can be easily expected that web accessibility issue is becoming more and more important. While information technology has changed Korean society rapidly and widely, there are many People who have difficulties in using information services such as the elderly and persons with disabilities. One of the big barriers they face is the lack of accessibility of web services. These social problems have been rarely studied in Korea but surface as very import subjects to be addressed concerning IT and welfare policy. The objective of this study is to ensure web accessibility right for visually handicapped and reduce digital divide through development of a recommendation guideline of mobile internet user interface. In this study the trends of politics and laws related to web accessibility in developed countries are surveyed and some advisable recommendation guidelines of mobile internet user interface for visually handicapped to improve web accessibility are proposed.
