For joint value creation, collaboration among different interested parties is vital and should be supported by information technology. Currently, both government and private companies have launched websites to collect ideas. However, the information poor, including the visually disabled, have difficulty in gaining access to those websites. Therefore, the aim of this paper is to evaluate the level of web accessibility to websites, operated by companies or the government, for idea proposals. According to the automatic assessments, regarding proposal specific websites, 77%, 69% of the websites operated by the government and 41%, 44% of those operated by private companies were extremely inadequate. According to the expert's assessments, regarding proposal specific websites, 67%, 52% of the websites operated by the government and 39%, 26% of those operated by private companies were extremely inadequate in their level of accessibility. A range of policies should be prepared to improve web accessibility.

This study is intended to analyze the relation between G. D. Weisman's Way finding 4 elements the accessibility and efficiency of consumers as to eternal area for Seoul historical museum. The findings are summarized as the following three aspects. First, G. D. Weisman's Way finding element introduced in this study had a significant impact on visitor satisfaction.. It leads to the following conclusion: The higher the impact is, the greater accessaccessibility and efficiency are. Second, among 4 elements, the factor that had the biggest impact on the accessibility was 'visual-perceptual accessibility'. Thus, 'visual-perceptual accessibility' should be considered first to boost the accessibility to consumers. Third, among 4 elements, the factor that had the biggest impact on the efficiency was 'sign system'. Thus, 'sign system' should be considered first to boost the efficiency to consumers.

Ubiquitous web services have been expanding in various business areas with the evolution of wireless Internet technologies, accessible and usable with a variety of mobile Internet devices such as smart phones. Ubiquitous mobile-web information services can be evaluated for accessibility and usability with the mobile Internet devices interacting with mobile-web information servers. In human mobile-web activity, a web server could be a unified center for mobile-web interaction services as well as for real-time estimation and analysis of mobile-web interaction sessions. We present a real-time estimation and analysis scheme for time-based accessibility and usability in ubiquitous mobile-web services. With real-time estimation/analysis of sessions in a mobile-web server, we estimated the time-based accessibility and usability for comparison between different web services as well as for applications in mobile cloud computing services. We present empirical results based on the implementation of the real-time estimation/analysis scheme.

According to the statistics revealed by Bank of Korea on March, 2007, Internet banking transactions outnumbered face-to-face banking services in Korea. Internet banking is becoming essential in every financial service sectors. For people with disabilities, Internet banking is more meaningful because they do not need to visit the bank, thereby saving inconvenient trips. Governments in many countries are working on setting standards and laws on the web accessibility for people with disabilities. Korea government enacted Korea Disability Discrimination Act in 2007. This paper examined the web accessibility compliance of Internet banking sites. Twenty one Internet banking sites were selected from the list in the Korea Federation of Banks's Web sites. We examined four major checkpoints that are considered crucial among the fourteen checkpoints in "Internet Web Contents Accessibility Guidelines" which was amended by Ministry of the information and Communication in 2005. The results showed that all of the twenty one Internet banking sites didn't meet the four major checkpoint requirements. Moreover, only one banking site satisfied alt-text requirement that is considered the most fundamental among the checkpoints.

Importance of Web accessability for handicapped persons is ever increasing in the information society with increasing role of the Web. The Web accessibility of handicapped person related Web sites were compared with the school Web sites in order to figure out the realities of handicapped person related Web site's accessibilities. According to the experiment, the Web accessibility of handicapped person related Web sites got lower scores than general school Web sites. The research result shows that more improvement efforts for the Web accessibility of handicapped person related Web sites are required.

The paper has developed a methodology of calculating accessibility in bus network by using a space syntax technique. The purpose is an effective analysis of accessibility improvement before and after Seoul bus reorganization. Space syntax methodology has an advantage to calculate easily network connectivity and accessibility. However, it also has a weakness not to consider the distance and travel time for calculating accessibility. As a result, we have developed a hybrid of the space syntax methodology and the travel time measures. This method has been applied to evaluate the accessibility before and after the hierarchical bus systems introduced in Kangnam area of Seoul.

Mobile SNS like facebook is famous as an app which users cooperate others and share information without regard to time and place. But it is necessary to evaluate the mobile app accessibility in view of the disabled and the aged to check if they get appropriate interface service to use such a popular app. Mobile app accessibility is an indicator of equal opportunity to mobile app for all users regardless of cognitive and physical attribute. Therefore, this paper evaluates accessibility of facebook and kakaotalk mobile SNS, apprehend the status of conform to the manual, and suggest an improving way, based on 'mobile application accessibility guideline' announced by government and 'mobile application (Android) accessibiliy checking manual(v1.0)' by National Information society agency.

This study aims to quantitatively evaluate the conservation priorities of unexecuted urban parks in Seoul both from an ecological and public perspective. To this end, two methodologies, ecological network analysis based on graph and circuit theory and accessibility analysis, were employed in order to assess ecological connectivity of and public accessibility to unexecuted parks, respectively. This study applied linkage-mapping methods (shortest path and current flow betweenness centrality) of connectivity analysis to an integrated map of landscape permeability. The population-weighted accessibility to unexecuted parks was measured based on a negative exponential distance decay function. As a result, for both ecological connectivity and accessibility, Gwanaksan, Suraksan, and Bulamsan urban natural parks are found to be the most important (rank 1-3) to be conserved. For these sites, inner park areas with conservation priorities for connectivity and accessibility were identified. The findings of the study can be used for giving conservation priority to the unexecuted urban parks in terms of long-term sustainable urban planning.

According to the increase of rural experience, that is important in satisfying needs of green tourism and vitalizing rural economy to use closed school in rural area as experience facility. For using closed school as experience facility, political and institutional assistants are needed in effective equipments and stable operation based on multi-perspective approach and analysis. In this study, we try to evaluate green-tourism accessibility of rural experience facility remodeled from closed school considering regional population and spatial characteristics. In evaluating process, gravity potential model are adapted with considering group size of customer and distance-friction coefficient. Distance-friction coefficient is a function of user restriction which depend on possible activity in each experience facility. Green tourism accessibility of experience facility is calculated with summation of accessibility to each region, and we analyzed it as a group by closed school type and location with application in Chungcheongnam-do. We found a correlation between green tourism accessibility of rural closed school and their income.
