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.

이러닝 학습은 다양한 목적을 지닌 많은 대상들에게 눈부실만한 기여를 하고 있음에도 불구하고 이러닝의 특성을 가장 절실히 필요로 하는 장애인과 노인 등의 소외된 사람들에게 혜택을 주지 못하고 있다는 점은 안타까운 일이다. 이러한 현실에 대하여, 그동안 정보통신기술분야에서도 소외된 대상들을 고려한 접근성 관련 제도적 개선이 이루어져 왔다는 점을 상기한다면, 자성만이 아니라 그 이유를 조사할 필요가 있다. 따라서 본 연구의 목적은 이러닝 기업 CEO의 인식을 조사하여 웹 접근성과 관련한 제도적인 여건 속에서도 학습 환경에서는 여전히 접근성 개선이 이루어지지 않는 이유를 찾아보고 개선 방안을 제시하는 데 있다. 위의 목적을 위하여 현업에 종사하는 운영자와 개발자들을 대상으로 보편적 교수 설계을 위한 이러닝의 접근성 관련 인식을 조사하였다, 그 결과 이러닝 접근성에 대한 CEO의 인식은 매우 저조하며, 중요성에 대해서는 공감하나 비용적인 부담으로 인해 보편적 이러닝 콘텐츠 개발은 불가능하다고 생각하고 있었다. 이러닝 기업 CEO의 낮은 인식은 곧 개발자와 교수설계자들에게 접근성 기술 적용의 필요성을 강조하지 않는 결과를 초래하고 있다. 이에 대한 개선을 위해서는 우선 정부와 관련기관의 적극적인 홍보와 제도적 장치가 필수적이며, 현재 제공되는 이러닝의 접근성 개선을 위한 연구와 지원방안이 필요하며, 구체적으로는 보편적 학습설계와 접근성에 대한 교육과 확산을 위한 대안이 필요하다.

This study analyzes the accessibility patterns for commuting trips in Seoul Metropolitan Area using National Census Data between 1990 and 2000. the results show that the accessibility increased between 1990 and 1995, while it decreased between 1995 and 2000, due to the raised commuting time. Seoul, Kangju, Yeuju, Yangpyoung, Gapyoung show relatively high accessibility. The GINI parameters tell that the regional balance for commuting accessibility were worsen between 1990 and 1995, compared to that between 1995 and 2000. The accessibility patterns for commuting to Seoul were also analyzed and the result shows that the accessibility reduced between 1995 and 2000. Kwachun, Kwangju, Sungnum are found to have very high accessibility to Seoul, which is close to Soeoul with high percentage of incoming commuting trips. These results indicate that even continuous transport infrastructure supplies were not enough to solve the congestion problems for commuting trips in Seoul Metropolitan Area because of the induced traffic and traffic congestion.

In order to delivery of the correct information in IoT environment, it is important to deduce collected information according to a user's situation and to create a new information. In this paper, we propose a control access scheme of information through context-aware to protect sensitive information in IoT environment. It focuses on the access rights management to grant access in consideration of the user's situation, and constrains(access control policy) the access of the data stored in network of unauthorized users. To this end, after analysis of the existing research 'CP-ABE-based on context information access control scheme', then include dynamic conditions in the range of status information, finally we propose a access control policy reflecting the extended multi-dimensional context attribute. Proposed in this paper, access control policy considering the dynamic conditions is designed to suit for IoT sensor fusion environment. Therefore, comparing the existing studies, there are advantages it make a possible to ensure the variety and accuracy of data, and to extend the existing context properties.

With the rapid progress toward a new cataloging model, the revision of Korean Cataloging Rules (KCR) are under discussion. The purpose of this study is to make a suggestion on constructing authorized access points for multilingual works, especially focused on the language and script of authorized access points. To the end, this study investigates (1) the extended functions and meanings of access points on the new model, (2) related guidelines and regulations reflected in International Cataloging Principles and typical cataloging rules, and (3) the characteristics of access points in the current Korean cataloging practices. Finally, (4) desirable languages and scripts of authorized access points representing multilingual works are suggested.

Recently, Korean government has, enacted "Individuals with Disabilities anti-Discriminatory Act" in 2008, and is actively promoting the law. However, it is still at its infancy in comparison to other advanced countries in terms providing access for all users. Educational digital contents offered through cyber home learning need to be universally designed to include all learners. This study, I have analyzed the accessibility of K cyber home learning contents using FAE tool, and the result showed low scores or failed for 'HTML Standards', 'Scripting' and the 'Text Equivalents.' To assist digital contents' accessibility, UDL 7 principles could be use to improve accessibility and universality for learner-centered designs. Use of UDL will include learners with and without disabilities to learn from educational digital contents.

People with disabilities have been influenced by information technology tremendously. The influence of information technology on people with disabilities varies according to types and degrees of disability. This study analyzed the relationship between information accessibility and types and degrees of disability. Information accessibility is measured PC and internet use and disability classified into 10 types and 3 degrees per given type. The major findings of this study are as follow: (1) there are significant effects of types and degrees of disability on information accessibility; (2) there are differences of information accessibility ranking according to the types of disability between in Korea and USA; and (3) the relationship between degrees of disability and information accessibility is not linear. To accurately assess the level of information accessibility of people with disabilities, disability should be treated as a continuous variable that has values in types and degrees of disability.

It is likely that the spatial structure of the intraurban accessibility as well as the accessibility value of each of the nodes in the subway network is affected by the addition of new linkages. The changes in the accessibility at individual nodes also affect the accessibility in the surrounding areas at some distances away from the nodes. Graph-theoretic algorithms have been developed as a proper measurement scheme for the nodal accessibility in tracked transport networks such as subway networks. However, the graph-theoretic measurements have limitations to estimate the spatial diffusion effect on the surrounding areas. This study proposes a new model for the spatial diffusion effect estimation of nodal accessibility increment in the subway network toward the surrounding areas. Since the distance decay trend of subway station use reflect the spatial diffusion effect of the accessibility of subway station toward the surrounding area. The model is deduced from the subway station use density function which is formulated by the questionnaire survey data.

교차로 접근지체의 산정은 간선도로의 서비스수준 평가에 있어서 가장 중요한 요소 중의 하나이다. 교차로 접근지체는 상류부 교차로에서 진입하는 교통에 대한 균일지체와 그 이외 단일로 상에 존재하는 세가로등에서 유입되는 교통에 대한 무작위지체, 1회의 신호주기에 교차로를 통과하지 못한 교통에 대한 잔여지체 등과 연동보정계수를 이용하여 산정된다. 우리나라를 비롯한 대부분의 나라에서는 미국에서 차량의 지체와 연동보정계수를 이용하여 개발된 교차로 접근지체 산정식의 구조를 그대로 수용하고 있다. 그러나 도심부 신호교차로 사이의 단일로에 보행자를 위한 횡단신호가 설치되어 있는 경우, 이러한 단일로 횡단신호가 하류부 교차로의 접근지체에 미치는 영향이 있을 것으로 판단한다. 따라서 미국과는 달리 신호교차로간의 간격이 크고, 단일로 상에 보행자용 횡단시호 설치가 빈번한 우리나라의 실정에서는 이에 대한 영향을 분석하여 교차로 접근지체 산정 시 이를 반영하는 것이 바람직하다. 본 연구에서는 단일로 횡단신호가 하류부 신호교차로에서의 접근지체에 미치는 영향을 분석하기 위하여, 상류부 교차로와 단일로 중간부 횡단보도와의 거리, v/c 비, 신호 offset 등 상황을 설정하여 TRANSYT-7F를 이용하여 시뮬레이션을 수행하였다. 본 연구에 의하면 단이로 중간의 횡단신호가 상류부 교차로의 신호와 연동되지 않는 경우에는 하류부 교차로의 접근지체에 미치는 영향이 거의 없는 것으로 나타났으며, 연동 시에는 상류부 교차로와의 거리, v/c 비, 신호 offset 등에 따라 최고 80% 이상 까지 접근지체가 증가하였다. 일반적으로 신호 offset이 40%에서 60% 사이로 연동상태가 불량할수록 하류부 교차로에서의 접근지체가 증가하는 것으로 나타났으며, 그 외에 변수에 대하여서도 신호 offset에 따라 다른 정도로 접근지체에 영향을 미치는 것으로 나타났다. 따라서 현재 우리나라의 신도시 개발 시 일반적으로 나타나는 대규모 구획(super block)과 이로 인하여 불가피한 단일로 중간부의 횡단신호의 설치는 교통운영 측면에서 재고되어야 할 것으로 판단된다.
