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.

본 논문에서는 강의평가 시스템을 이용하여 주된 이용자인 학생들에게 수업에 앞서 강의에 대한 전반적인 학습 분위기와 강의를 들었던 학생들의 평점을 제안한다. 이 시스템은 강의평가를 효율적으로 보여주어 수강 신청의 접근성을 최대화하고, 각 강의의 안내와 정보를 취득하는 데 도움을 준다. 또한, 이 시스템은 네 가지의 평점을 부여하여 이를 바탕으로 종합적인 평점을 할당한다. 이때 강의평가에 대한 평가를 곁들이면서, 평점을 제시하여 강의평가를 보려는 다른 이들에게 뚜렷한 정보력과 어떤 강의가 좋은지 잘 보여준다. 본 논문에서는 동적 웹 페이지를 사용하여 가시성이 뛰어난 강의평가 시스템을 제공하는 면에서 우수함을 보인다.

The purpose of this study was to compare the emotional responses of people with visual disability with those of normal people and to understand their similarity or differences in order to apply the new understandings into the future research on Web Accessibility Guidelines. For this purpose, a Web survey system was developed using 15 auditorial stimuli prepared based on the Media Taxonomy and 11 emotion measuring criteria selected from the literature review. After developing the system, emotional responses of 31 people with visual disability and 53 normal people were collected through the Web. The results of the survey showed that the emotional responses of people with visual disability were similar to those of normal people, although there were some exceptional cases. Therefore, it is clear that emotional needs of people with disability should be taken count of in the Web accessibility discussions and further in-depth studies on the emotional characteristics of people with disability are necessary.

The peformance and quality of Web sites are often being estimated by the frequency that the users approach its site. This paper suggest how a link-editing method can automatically fix a poor organization by calculating each page's relative popularity, and how improve fix poor pages. Page's relative popularity depended on only cases where the objective Is to make it easier for a user to find the requested data; the faster the access, the better the organization of the Web sites according to tree depth.

Web-based Assessment System is needed for Process-Oriented Evaluation to integrate instructions into evaluation frequently in Informatics Education, and considered usability for supporting teachers to test more conveniently. First of all, we analyzed usability of traditional Web-based Assessment System, and proposed PBA(Paper-Based Assessment) model by extracting usability features of paper-pencil assessment in off-line. The evaluation system based on the PBA model controls the whole processes of tests; before-test, under-test, after-test. Especially, the system readily can change the target class, and control access to the test page during each step. Thus we can get high credibility about the test results. Moreover, students can login to the paper easily by using their grade, class, number and name. Finally, we designed and implemented the Web-based Assessment System for Informatics education on the basis of PBA model; PAS(PBA-based Assessment System).

In this paper, we study improvement of web accessibility of Korean Internet shopping mall websites. First, we analyze the criteria of Korean web accessibility, and then evaluate the web accessibility level of major Internet shopping mall websites in Korea. Based on the evaluation of web accessibility level, we propose and implement an alternative text enhancement method using Excel VBA to increase the rate of alternative text for improving web accessibility. Using the proposed method, even non-specialists of web programming can check and modify the alternative text of the image included in web pages, which can help improve the web accessibility compliance rate.

This research was examined to evaluate whether the websites of 6 policy research institutes provide web resources which were collected and provided as information resources, and that they were sure that the web resources had value as policy information by content analysis method. Web resources provided as policy information in policy research institutes were classified into and evaluated by 4 categories. Evaluation had been conducted on 10 items in the 4 categories of content, design, accessibility and meta data. From the result, the information content have been found to be reliable and up-to-date although more thorough description is required. Navigation and the search function in the design category were found to be excellent, but dead links were present in all of the institutions. The accessibility was proven to be great as it was able to access information with only three clicks. However, it has been found that a comprehensive review of the meta data is required in order to improve the accuracy of search functions. In conclusion, improvements to the dead link problems, quality control of the meta data, systematic and professional management plan of policy research information, and the establishment of a comprehensive policy research information portal system have been proposed.

인터넷 발달로 인한 정보격차는 장애인들의 문화지체현상을 가속화 시키고 있다. 이에 웹사이트의 원스톱 서비스에 있어 경험에 기초한 디자인과 보편적 디자인을 기반으로 접근성을 확장해 나가야 할 것이다. 본 연구에서는 문헌을 통해 장애인을 위한 접근성 필수항목 7가지, 즉 콘텐츠구성, 키보드접근, 마우스접근, 이미지처리, 텍스트처리, 색, 코드를 선정하고 이를 근거로 장애인 자료실이 있는 공공도서관과 그렇지 못한 공공도서관, 해외 공공도서관의 웹사이트를 대상으로 평가하였다. 이를 토대로 접근성 확장을 위해 메인페이지 개선, 사용자 경험을 기초한 콘텐츠 구성, 콘텐츠의 접근성, 의미 있는 마크업, 이용자를 위한 맞춤형 콘텐츠, 제작 권장사항 등을 제안하였다. 앞으로 장애인을 포함한 모든 이용자를 위한 웹 접근성 지침은 경험적 데이터와 보편적 디자인에서 이루어져야 할 것이다.

Until the 4th Industrial Revolution fused the Web with diverse technologies, the only factor in evaluating the performance of a Web application was the loading speed of the Web application. Therefore, most existing Web application performance analysis tools focus on the speed at which Web applications run in a Web browser. However, the web is now being used not only in a simple web browser but also in a variety of services. So, in addition to simple speed, there are more elements to be checked to evaluate web applications. Therefore, in this paper, we design a server to perform web application performance analysis considering progressive web app, accessibility, best practice, and search engine optimization as well as the above mentioned speed. Also, we realize a REST API based server that can provide web application performance services without being affected by user's devices or environment.

This paper proposes a new implementational model based on the security model of Oracle for Web ontology. Recently, several access control models using relational database security model for access control to Web ontology have been developing, and one of the most representative access control model is the RAC model. However, the RAC model is based on the standard security model, and thus it does not provide a implementational model for practical relational database management systems. In this paper, we propose an implementational model based on Oracle which is widely used and providing various security policies. This paper shows the implementation and experimental evaluation. Especially, the proposed model uses the VPD security model of Oracle and support high application and usability.
