In recent years, the efforts for standards of Web contents accessibility and improvements of Web accessibility are expanded in the government, public institutions, university, enterprises. Korean Web Accessibility Guidelines, KWCAG 2.0, by comparison with 1.0, was able to provide more define alternative text in terms of image content, enhance guidance for accessing and use of the keyboard and for a clear distinction of data tables. In this paper, we developed a CMS(Content Management System) for everyone to be able to access to information easily in the mobile/web environments that are changing rapidly. The CMS, which is developed in this paper, is designed and manufactured based on KWCAG, W3C XHTML-1.0-Strict DTD, W3C CSS2 web accessibility and web standards. CMS builder is a WYSIWYG manner making it easy to use and manage, as well as a variety of the web was to operate in a mobile environment.

This paper proposes new algorithms of accessibility indices to analyze the connectivity of the Korean highway network. First of all, we find a transportation network that presents Korea's highway network in graphs in 2011 and 2017. And we analyze and compare the nation's highway network in 2011 and 2017 using concepts such as associated number, the relative distance, the accessibility, the degree of connectivity, the index of dispersion, the diameter of graph theory. To do this, an algorithm is presented which can easily obtain various accessibility indices from a given transportation network. Using the simulation results of this study, we can find city that is the center of traffic in the highway transportation network. In addition, cities that are included in the network but are relatively underdeveloped can be found and used as basic data for enhancing the connectivity of the nationwide traffic in the future. Moreover, the proposed algorithms of accessibility indices, which are modeled on highway transport networks, can help identify the accessibility space structure of each city and provide criteria for efficient and reasonable selection of alternatives in various regional planning processes, including transportation.

Background: The purpose of this study was to identify factors affecting unmet healthcare needs due to physical accessibility by residential area by utilizing the Korea Community Health Survey (KCHS). Methods: Andersen's medical service behavioral model was applied to analyze the enabling factors, predisposing factors, and needs factors of unmet healthcare needs focusing on residential areas. This study used data from the KCHS (2017-2019, n=440,792). We used multivariate survey logistic regression analysis in order to identify affecting factors. Sub-group analysis was conducted in order to evaluate the effects of residential areas. Results: Some participants (2,621, 0.59%) had experienced unmet healthcare needs due to physical accessibility and 2,047 subjects (78.1%) of them lived in rural areas. Multivariate survey logistic regressions revealed that experience of unmet healthcare needs due to physical accessibility increased when people lived in rural areas (odds ratio [OR], 3.95; 95% confidence interval, 3.46-4.51). Conclusion: This study showed that despite the development of transportation and efforts to alleviate medical inequality, residents in rural areas may still have higher experience of unmet healthcare needs due to physical accessibility compared to the metropolitan city regardless of any other sub-group differences (OR range, 1.90-6.31). This study suggested that government and policymakers should identify the causes of the experience of unmet healthcare needs due to physical accessibility and should develop policies to alleviate those healthcare disparities.

Owing to our rapidly aging society, accessibility evaluation to enhance the ease and safety of access to indoor and outdoor environments for the elderly and disabled is increasing in importance. Accessibility must be assessed not only from the general standard aspect but also in terms of physical and cognitive friendliness for users of different ages, genders, and abilities. Meanwhile, human behavior simulation has been progressing in the areas of crowd behavior analysis and emergency evacuation planning. However, in human behavior simulation, environment models represent only "as-planned" situations. In addition, a pedestrian model cannot generate the detailed articulated movements of various people of different ages and genders in the simulation. Therefore, the final goal of this research was to develop a virtual accessibility evaluation by combining realistic human behavior simulation using a digital human model (DHM) with "as-is" environment models. To achieve this goal, we developed an algorithm for generating human-like DHM walking motions, adapting its strides, turning angles, and footprints to laser-scanned 3D as-is environments including slopes and stairs. The DHM motion was generated based only on a motion-capture (MoCap) data for flat walking. Our implementation constructed as-is 3D environment models from laser-scanned point clouds of real environments and enabled a DHM to walk autonomously in various environment models. The difference in joint angles between the DHM and MoCap data was evaluated. Demonstrations of our environment modeling and walking simulation in indoor and outdoor environments including corridors, slopes, and stairs are illustrated in this study.

A quantitative descriptive survey was conducted to assess the needs of elderly people in relation to accessibility of medical care. Identifying their functional status was done and accessibility of medical care was ascertained. Using a convenient sampling method, 856 elderly aged 65 and over in Taejon-city participated. A multi-dimensional questionnaire containing sections on health status, Activities of Daily Living(ADLs) and accessibility of medical care in terms of use, time, distance, transport, cost and feeling at ease was developed by the researchers of this study to collect data. Data were collected between October and December, 1999. In general, the result of the self-reports from this study found that approximately 40% of participants had difficulties with their health status and ADLs while about 45% of the population did not access medical care. The majority of respondents stated that they had no difficulties with time distance and transport to access medical care. About two-thirds of the respondents felt that they had many or some difficulties with expenses and strategies for emergency to access medical care. Even though these findings need to be generalized, several recommendations for appropriate medical care delivery for the elderly still can be outlined from the study findings. Recommendations suggested are: To identify impediments to access medical care in emergency in elderly people and to remove those factors preventively are required. Responsible governmental involvement for solving problems of the medical care cost and additional costs in relation to separation of dispensary from medical practice for the elderly is required. More constructive and practical uses of public health community centers are recommended.

Efficient data dissemination is one of the important subjects for sensor networks. High accessibility of the sensed data can be kept by deploying the data centric storage approach in which data is stored over the nodes in the sensor network itself rather than external storages or systems. The advantage of this approach is its direct accessibility in a real-time without the severe burden on delay and power dissipation on the data path to the external storages or systems. However, if the queries from many users are concentrated to the few nodes with data, then the response time could be increased and it could lead to the reduction of network life time by rapid energy dissipation caused by concentrated network load. In this paper, we propose a adaptive data centric storage scheme based on proxy trajectory (APT) mechanism. We highlight the data centric storage mechanism by taking account of supporting large number of users, and make it feasible to provide high-performance accessibility when a non-uniform traffic pattern is offered. Storing data around the localized users by considering spatial data-access locality, the proxy trajectory of APT provides fast response for the users. The trajectory, furthermore, may help the mobile users to roams freely within the area they dwell.

Public transit services are generally analyzed based on the correlation of demand and supply. The computation of supply uses accessibility while demand uses travel demands estimation based on residential population. However, the traditional demand estimation has a limitation in analysing in micro-scale compared to the smartcard data traffic. This study analyzed potential improvement of public transit services using smartcard traffic data. The supply of transportation was defined using time distance accessibility. Also, time loss was calculated in those origin destination(OD) pairs where time distance accessibilities are relatively low. The proposed method was applied at Seoul. The results showed that the areas where OD pairs need improvement include Seodaemun-gu, Guro-gu and Nowon-gu.

Accessibility is the generalized definition on how ease of access. Accessibility is used to appraise transportation project such as capturing the quality of the existing state of the transportation system at diverse spatial levels, It also reflects on the effect of improvements to the existing travel modes and the intoduction of new modes. The overall goal of this study is to propose a measure of urban accessibility in Seoul which can analyze various behavior of travelers in the city and to present applications. In this study, we apply measures of accessibility which are developed by CTR(The Center for Transportation Research, the University of Texas at Austin) to construct the urban accessibility index applicable for explaining trip behavior in Seoul. We evaluate sustainability of urban transport system in Seoul in 2002 by using the MAG(Modal Accessibility GaP) index which is developed to measure the accessibility gap between the more energy-efficient mode and less energy-efficient mode of transport. By analyzing the change of MAG index between 2002 and 2004 based on network data, we show how the public transportation system reform affect the sustainability in transport system.
