The citizens seek to maximize convenience, pleasantness and safety when they use urban facilities. However, existing practices of urban neighborhood parks have applied not qualitative standards such as adequacy, efficiency, accessibility, equity, or socioeconomic issues but very limited quantitative standards such as area per person. Therefore it is not rare that citizens have lost their accessibility to near-by neighborhood parks. And park regulations based on the distance of lien are supposed to be uniformally accomplished regardless of the consideration about users or geographical special situations. Futhermore, it has been found that some urban neighborhood parks don't reach to the standards given by the regulations. This study tries to accomplished several purposes. The first purpose is to extract the boundary of real user-accessible zones derived from the city survey. Comparing with boundary of real user-accessible zones, the second one is to propose the most efficient measurement indices among many accessibility measurement index. Based upon the above arguments, the last one is to review the propriety of the access distances(e.g., semidiameter) of an urban neighborhood park in a law. The measurement indices of accessibility examined in this study are walking distance, walking time and walking difficulty. The comparison of visual discrimination, the comparison of area and the comparison of differences of maximum distance showed similar results. Each index can also be compared in the size of area and differences of maximum distance. Walking difficulty with the turning showed the best measurement values among the measurement indices. This indicates that walking difficulty with crossing and/or turning may be another important indices in measuring accessibility, while other existing studues have mainly dealt with walking time and distance as accessibility indices. The results of this study also supported that the existing regulations related to park allocation(e.g., access diameter) are close to the findings of this study.

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.

As the economy of Korea has developed, dietary patterns have also changed in many ways. Rural areas, in particular, demonstrate relatively lower food accessibility than in urban areas. The aim of this study was to examine whether or not there were differences in food accessibility between urban and rural areas using data of the Census on Basic Characteristics of Establishments, Consumer Behavior Survey for Food, of the Korean National Health and Nutrition Examination Survey. Also investigated was how such differences would affect the frequency of food purchase, dietary intake, and nutrition intake by district. The results showed that districts with the lowest 10% in food accessibility had lower frequency of food purchase than did the highest 10% districts. In terms of nutrition intake, the daily average nutrition intake was not significantly different among districts. Yet, analysis of the amount of weekly dietary intake indicated that food oasis districts had from 1.3 to 3 times greater dietary intake than did food desert districts. These findings mean that the difference in food accessibility causes unbalanced food intake. Thus, the government must take a comprehensive approach to ensure that rural residents get greater food accessibility.

This paper examines the (a)symmetries in the realization of focused subjects and objects in Korean. Through rating experiments, we demonstrate that native speakers' judgments of acceptability of sentences containing case-marked or case-ellipsed subjects and objects are sensitive to the contrastiveness strength and the discourse accessibility of focused arguments. However, our experiments also show that focused subjects exhibit stronger preference for explicit case marking over case ellipsis and that contrastiveness strength and discourse accessibility have weaker influence on the case marking and ellipsis of focused subjects compared to focused objects. We propose an account of variable case marking that is capable of subsuming both the similarities and differences between focused subjects and objects under the universal theory of markedness. In particular, it is shown that the similarities between focused subjects and objects are predicted by the proposed account based on the contrastiveness strength and the discourse accessibility of focused arguments and that the differences between focused subjects and objects follow naturally from the relative markedness of focus as subjects.

Home modification has come to be recognized as an important intervention strategy to manage health care conditions, maintain or improve functioning, ensure safety, and reduce the wheelchair user's dependency on others. However, the availability of skilled professionals with experience in home modifications for accessibility is limited. A system that enables accurate remote assessments would be an important tool to improve our ability to perform home assessments more easily and at decreased cost. A Remote Wheelchair Accessibility Assessment System (RWAAS) using Virtualized Reality(VR) technology was developed that enabled clinicians to assess the wheelchair accessibility of users' built environments from a remote location. Characteristics of the camera and 3D reconstruction program chosen for the system significantly affect its overall reliability. In this study, we performed two reliability analyses on the hardware and software components: 1) Verification that commercial software can construct sufficiently accurate 3D models by analyzing the accuracy of dimensional measurements in a virtualized environment; 2) comparison of dimensional measurements with four camera settings. Based on these two analyses, we were able to specify a consumer level digital camera and the Photomodeler Pro software for this system. And we then tested the feasibility of the selected software and hardware in an actual environment. Lastly, A field evaluation was performed to test whether this new system is comparable to the traditional method of accessibility assessment to evaluate its ability to assess the accessibility of a wheelchair user's typical built environment. The results of field trials showed high congruence between the assessments by two methods. Findings suggested that the RWAAS assessments have the potential to enable specialists to assess potential accessibility problems in built environments regardless of the location of the client, home, or specialist.

This study examined whether the Fair Housing Amendments Act of 1988 (FHAA) in the US provides more home accessibility features and reduces the home accessibility problems of senior residents with physical disability. The 2011 American Housing Survey data with a sample of 2,326 senior residents age 55 and over with physical disability and living in multifamily housing built between 1970 and 2011 were analyzed. We compared senior residents living in multifamily before (1970-1990) and after (1991-2011) the FHAA. The results show that senior residents living in multifamily housing before the FHAA were at a greater disadvantage because they were more likely to live in older buildings located in urban areas, yet paid lower rent and received government subsidies. This study confirmed that the FHAA enabled residents of multifamily housing to have more home accessibility features. However, there was no significant difference in perceived home accessibility problems between the two groups, indicating that senior residents in multifamily housing have experienced home accessibility problems both before and after the FHAA. This study has important implications for housing policy makers to consider home accessibility features for multifamily housing buildings before the FHAA, and to revisit if the FHAA sufficiently compensates physical disability of senior resident living in multifamily housing after the FHAA.
