Urban park facilities and services offer a number of opportunities to fulfill individual, social, economic, and environmental benefits. Urban parks, provided through political measures as public goods, require balanced distribution in order to ensure social equity. The primary objectives of this study are to analyze the accessibility of urban parks and to examine whether urban parks are distributed equitably. GIS and statistical methods were used to investigate correlations between accessibility to neighborhood parks and socioeconomic status. As results, percentage of low-income population within the city was negatively related to park accessibility. Low-income dominated residential area, such as Sujeong-gu and Jungwon-gu have large low-income communities and less park accessibility compared with Bundang-gu, which are dominated by high-income residents. So, results from this study indicate that urban parks are not distributed equitably within Seongnam city. Therefore, creative strategies to provide urban parks for areas in need through the utilization of vacant lots, abandoned sites, and schools sites are necessary. Furthermore, budgetary priorities should be set to create new parks and revitalizing parks within the city's older neighborhoods are also needed.

The purpose of this study is to extract deficiency areas as basic data of policies and projects in the future Living SOC introduction and planning. In order to extract living SOC deficient areas, accessibility data for living SOC and density data for main users by facility were overlapped, focusing on the living SOC indicators presented in the National Urban Regeneration Basic Policy. According to the analysis of accessibility of the Iksan-si Living SOC, the gap between deficiency in urban and township areas was large in common with the accessibility of the village and local base units. As a result of overlapping life SOC accessibility data and density data analysis of the main users by facility, areas where accessibility is weak but not inhabited by the main users of each facility were extracted. It is meaningful that more accurate deficient areas can be extracted by simultaneously utilizing the density distribution of the main users, rather than simply accessing the facilities.

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.

This study is about that how accessibility or norm influence to use diversity or usage of internet contents. Two hypotheses tested by statistic analysis. The major finding of this study are as follows. First, the greater the physical accessibility or intellectual accessibility, the greater the use diversity of internet contents. Second, the greater the physical accessibility or intellectual accessibility, the greater the usage of internet contents. Third, the greater the subject norm, the smaller the usage of internet contents. This study provides some implications that subject norm can influence to reduce usage of internet contents. The limitations, and future direction are discussed.

This study attempts at building an integrated GIS computing framework for evaluating space-time accessibility of an individual with the approach of time geography model. The proposed method is based on the integration of mobile GIS and object-relational spatio-temporal database. Three components are central to our system: ( i ) mobile GIS application that transmits spatio-temporal trajectory data of an individual; ( ii ) spatio-temporal database server that incorporates the time geography model; and (iii) geovisualization client that provides time geographic queries to the spatio-temporal database. As for the mobile GIS application, spatio-temporal trajectory data collected by GPS-PDA client is automatically transmitted to the database server through mobile data management middleware. The spatio-temporal database server implemented by extending a generic DBMS provides spatio-temporal objects, functions and query languages. The geovisualization client illustrates 3D visual results of the queries about space-time path. space-time prism and space-time accessibility. This study shows a method of integrating mobile GIS and DBMS for time geography application, and presents an appropriate spatio-temporal data model for evaluating space-time accessibility of an individual.

Travel is a factor that stimulates the vitality of the urban and is widely used as an indicator of sustainable growth of the region. In Korea, however, no studies has been made to predict changes in traffic and calculate the accessibility of the region by comprehensively considering the socio-economic conditions of the travelers. The purpose of this study is to classify commuters according to the household income and to analyse the traffic characteristics of each class. The analysis results are aggregated into two. First, the analysis of study found different transport characteristics for different income classes. This is the result that underpins the argument of a previous study that suggested that a discriminatory approach is necessary for each income in determining the accessibility of the region. Second, this study calculated utility values differently for each income class based on the transit time and cost required between each zone. Through these measures, transport characteristics were analyzed by income class using indicators that considered transportation infrastructure, and socio-economic conditions of the travelers. This study is meaningful in that it provided the basis for calculating the accessibility that could take into account the activities of the housing consumers in establishing domestic housing policies.

The introduction of high speed railway system a significant impact on the conventional inter-urban transport systems by inducing a significant traffic from the existing modes as well as generating a new traffic. It is also closely related to intra-urban transport systems as the inter-urban traffic has its origin and destination in a city. In the context of mode choice, for high speed transport systems, it has been argued that the accessibility is the most important attribute conceived by users. Thus this study attempts to analysis the importance of the accessibility for the planned high speed railway systems particularly with respect to the location of Busan Station. For this Stated-Preference approach, which is considered appropriate for such study, is adopted, and disaggregate binary logit models for mode choice between the high speed railway and air service in Busan-Seoul corridor are developed. The elasticities for cost and service variables are also derived. The results disclose that cost is the most important which is inconsistent with most previous studies ; accessibility has considerable impact on the choice ; and frequency however has a little impacts. Concerning location of the high speed railway station the results suggest that the longer the access distance is, the more important the accessibility is. This implies that the connection of reliable access transport services such as underground are essential between the terminal and urban center.

The Korean disabled is about 5% of the population and most of them utilize welfare centers for the disabled. The disabled have difficulties in using the welfare centers' website since many centers do not comply with the website accessibility guidelines. This paper has compared, evaluated and provided the analytical results of the observance of the website accessibility guidelines of the welfare centers for the disabled in Korean, the U.S. and Japanese. The results indicated that there are many social welfare centers which do not abide by the laws even though the welfare centers for the disabled should comply with the website accessibility guidelines as required by the Law of Prohibiting Discrimination and Right of Remedy for the Disabled in 2008. In particular, Korean welfare centers for the disabled observing the website accessibility guidelines is significantly low of 78.77% to be compared with the U.S. by 85.50% and Japanese by 86.00%. This paper will provide theoretical basis for research on evaluation of website accessibility in the future and contribute to the public awareness on the social welfare of the disabled by suggesting the future direction of website accessibility evaluation on the welfare centers which are closely linked to the everyday life of the disabled.
