Abstract

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.

본 연구는 정부 및 공공기관의 보건 관련 웹 사이트들의 웹 접근성을 한국형 지침에 따라 평가하여 장애인이나 노령자들과 같은 정보이용 소외집단들이 겪을 수 있는 문제점들을 파악하고자 하였다. 본 연구에서는 총 27개의 보건 관련 웹 사이트의 접근성을 자동평가 및 전문가 평가를 수행하여 측정하였다. 두 단계의 평가를 실시한 결과를 종합해 볼 때, 국립병원이나 국립재활원 등과 같은 의료기관들은 웹 접근성 오류가 거의 없는 것으로 나타났으며, 그 외에도 건강보험심사평가원, 보건복지부, 보건사업진흥원, 식품의약품안전처, 그리고, 한국의료분쟁 조정중재원 등은 웹 접근성 준수율이 매우 높았다. 그러나 전문가 평가를 실시한 결과, 자동평가에서는 오류가 없는 것으로 나타났던 적절한 대체텍스트의 제공이 매우 미흡한 것으로 나타났으며, 텍스트 콘텐츠의 명도 대비가 표준에 미치지 않아 전맹자나 저시력자들의 웹 접근성을 지원하기 힘든 것으로 평가되었다. 그 외에도 기본언어표시와 마크업 오류 등 정확한 정보의 전달을 어렵게 하는 문제들이 나타났고, 반복영역 건너뛰기, 콘텐츠 선형화, 그리고 키보드 사용보장을 준수하지 않는 문제들이 발견되어 시각장애뿐 아니라 인지장애 내지 운동장애가 있는 이용자에게는 웹 접근성을 심각하게 방해하는 요소가 될 수 있는 것으로 파악되었다. 본 연구는 국내 연구로서는 처음으로 정부 및 공공기관의 보건관련 웹 사이트들의 접근성을 한국형 지침에 따라 평가했다. 또한, 이러한 웹 사이트들을 대상으로 자동 평가로 측정하기 어려운 웹 접근성의 정도와 상세한 내용 분석을 포괄하는 전문가 평가를 수행했다는 점에서 웹 접근성 연구 분야에 기여했다고 볼 수 있다.
