  • Web accessibility refers to the practice of providing equal access to web sites to people without and with disability. This study aims to investigate the web content accessibility of 153 university libraries in Korea, and further suggest the approach to implement an effective university library web site to meet Korean Web Content Accessibility Guidelines(KWCAG). Survey was conducted with two steps. The first step was to find out the general level of web accessibility of all university library web sites using an automatic appraisal tool, KADO-WAH2.0, and the detailed examination of web accessibility check items was limited to 19 web sites which proved excellent in automatic appraisal. Regretfully, the result says that there is no perfect web site. Therefore every university library is advisable to make good use of the findings to meet all the requirements of KWCAG. In particular, the basic requirements, such as voice service, resizing and highlighting text, must be fulfilled by priority and to almost all contents.

  • The obligation of web accessibility in public center, education center, medical center and rehabilitation center started from 2009 has plan to adapt it to a corporation and culture and art until 2015 by stages. This study analysed in the aspect of statistics how well the domestic broadcasting system follows web accessibility which was evaluated by six automatic checking guidelines provided in KWA-H 4.3 automatic evaluation device. With Kruskal-Wallis' test result of nonparametric analysis, an item of basic language statement seemed to be highly followed(p=0.041) with broadcasting system> internet newspaper> the daily press> sports newspaper in order. An item of label offering was followed(p=0.015) with sports newspaper> broadcasting system> the daily press> internet newspaper in order.

  • 본 연구에서는 웹 접근성 평가를 위하여 기존의 문서의 배경색과 문자 색 사이의 색 대조 정의에 대한 알고리즘을 조사하고, 비교하였다. 현재까지 나와 있는 색 조합에 대한 색 대비의 정량적 정의는 가독성 측면에서 불완전하며, 사용자에 대한 시험 평가에서도 무시하지 못할 불일치를 드러내고 있다. W3C에서 색 대비 평가 방식으로 추천하는 토론토 대학의 웹 접근성 평가 수정도구인 A-prompt에서 사용하는 알고리즘과 미국 토양조사센터의 토양지도 작성을 위한 색 대비 평가 알고리즘을 비교 대상으로 하여 216개의 웹 안전 색의 조합에 대하여 총 46656개의 비교 평가를 수행하였다. 평가 결과 W3C의 기준은 미국 토양조사센터의 기준보다 대비기준이 너무 엄격하며, 전체 색조합의 94.7%가 부적절한 색 대비를 제공하는 것으로 판정 되었다. 따라서 W3C의 기준은 웹 문서 저작자의 색 선택을 상당할 정도로 제약하며, 적용 기준을 정상인에게도 혼란을 줄 수 있는 기준, 시각적 결함을 가진 사용자에게 혼란을 줄 수 있는 3단계의 기준을 적용하는 것을 제안한다. 추후에는 사용자 평가를 통하여 알고리즘의 타당성을 검증하고, 보완점을 제시할 예정이다.

  • The SNS(Social Network Service or Social Network Sites), the concept which came along with the Web2.0 is on-line service which focuses on building social network communities of people which used to be established off-line. Foreign SNS sites such as Facebook, MySpace and Twitter and domestic SNS sites such as Cyworld, Me2Day are getting popularity continuously and became one of the most important application in internet environments. Since these SNS sites have the purpose of providing infrastructure which enable all the people to share his/her interests with all the other people, it is necessary to appraise whether these sites provide convenient interfaces with proper accessibility to handicapped people and old people who are considered having difficulties in using internet. Web accessibility refers to the practice of providing equal access to people of all abilities and disabilities. If the web accessibility of a SNS site is so low that handicapped people and old people cannot use it properly, those gaps between user groups may become social problems. Therefore, the paper appraised web accessibility of Facebook and Cyworld using automatic tool, KADO-WAH 2.0 and Standard guideline, WCAG 2.0 and suggested the improvement opportunities based on the results of the appraisal.

  • This study, in the perspective of universal design, newly suggests UD-WCAG 2013 for the evaluation of job information sites used by the silver generation. Using this, 13 senior clubs run by social welfare corporations chosen by the central and local government for the silver generation job information provision organizations to analyze the compliance status of web accessibility. The web compliance status analysis was done through a self-assessment tool from Korea Agency for Digital Opportunity and Promotion and UD-WCAG 2013. Although both analyses showed that there weren't differences according to region, the general level of compliance was shown as low. In the UD-WCAG 2013's 7 major categories the part about errors was shown providing appropriate solutions, but in the other parts it was shown that the all 13 websites were being run with insufficient consideration of the social and physical characteristics of the silver generation.

  • This paper proposes methods of evaluating and measuring accessibility of accredited certificate subscriber software which is one of crucial applications to submit personal certifications while web surfing. The presented methodology is to evaluate accessibility by using a certain assessment tool and is to normalize accessibility level into points, so that the software developers who are unfamiliar to screen readers can easily perform accessibility evaluation. The software from the major 78 organizations has went through the assessment. Those of 48 organizations, 62% out of the total, have acquired less than 70 points, implying the software of them is not accessible by the blind. The remaining 18 software got the highest point(88), are partly inaccessible by the blind that uses screen readers. This implies that the proposed methods are applicable to evaluate the accessibility of the software.

  • This paper evaluates web accessibility using an evaluative measure of K-WAH 3.0. It targets systems and contents in scientific and technological information, based on a guide for 'Internet Web Contents Accessibility 1.0'. The result indicates that web accessibility of informational system is lower than that of informational contents. Based on this fact, this paper identifies the main characteristics and differences of web accessibilities in informational system and contents, and discusses possible improvements. the result of the evaluation found the scientific system sites is more superior than contents sites in web accessibility. And the scientific system and contents sites except NDSL was lest 'understandable' and 'Robust' in observance. Therefore web page that should bring "easily understandable" and "reducing outstanding side effects" was required.

  • 국내의 많은 연구를 통해 신재생에너지의 사전 경제성 평가를 위한 모델들은 다수 개발된 바 있지만, 기본적인 연산 프로세스와 연산방식만 지원되고 있을 뿐, 연산결과에 크게 영향을 미치는 신재생에너지의 각 요소 데이터가 제공되지 못하고 있다. 이에 대하여 본 연구에서는 한국에너지기술연구원에서 개발된 신재생에너지 자원지도 데이터를 근간으로 하여 경제성 평가의 기본이 되는 정보를 데이터베이스로 구성함과 동시에 GIS(Geographical Information System)을 활용하여 해당 영역에서 직접 대상위치를 선정하고, 인자값의 설정에 따라 사전 적정성 평가를 지원하는 연산 프로세스를 개발하고자 하였다. 웹 도구를 활용하여 사용자의 접근을 용이하게 하며, 설비데이터의 입력이 가능하게 구성하여 지속적으로 업데이트가 가능한 시스템의 제작을 그 목표로 한다.

  • Web usability is utilized as a standard for constructing and managing website to be useful by people of all abilities and disabilities. Link integrity is one of main criteria for web usability evaluation. Links that are found to be broken or pointing to irrelevant information lead gradual degradation of link integrity over time. This study has conducted investigation for link integrity of Korean public institution website. Among 49 website that are accessible by an automatic link checker software, 91.8% of the website has more than one broken links. Also average number of broken links is 50.5 that is 0.33% of the number of links. 29 websites consist of internal broken links. And 22 website do not provide any information on the missing page. Broken links enlower website confidence by reducing web usability as well as they prohibit web search engine not to provide information on the website. Therefore, web developers and managers need to be aware of importance of link integrity and prohibit web usability degradation by performing link validation as a web management task or periodically.
