It is not easy for users to effectively have information that is semantically related but scattered on the Web. To obtain qualitatively improved information in web pages, it is necessary to integrate information that is heterogeneous but semantically related. In this study, we propose a method that provides XML-based metadata to users through integration of multiple heterogeneous Web pages. The metadata generated from the proposed system is obtained by integrating different heterogeneous information into a single page, using entity identification based on ontology. A wheelchair information integration system for disabled people is implemented to verify the efficiency of the proposed method. The implemented system provides an integrated web page from multiple web pages as a type of XML document.

Ubiquitous services are high quality and differentiated services which are provided for users by recognizing the context of users and environmental conditions actively. In this case, context-aware middleware is one of the most important technologies required to implement the ubiquitous services. In this paper, we propose a method for providing ubiquitous services in a specific user space effectively and monitoring human bio-sensors. That is, the design and implementation of intelligent home service middleware and monitoring bio-sensors based on context awareness is discussed here. Context information from various sensors is gathered, and suitable services are inferred and provided to users by the middleware system. In our approach, user services can be modelled easily by using facts and rules, and the system can be extended easily to support various ubiquitous services other than intelligent home services also. The system can be integrated with external applications and legacy systems effectively by using various protocols such as RMI, socket and HTTP, XML and etc. We have designed and evaluated various facts and rules for intelligent home services in real environments. Functionality evaluation with the system shows that ubiquitous services can be provided to users effectively in a home environment.

The purpose of this study was to assess adequately equipped with convenience facilities for the disabled in 160 healthcare institutions in Jongno district, Seoul. Healthcare institutions were equipped an average of 3.7 facilities out of 10. General hospitals had an average of 5.0 facilities, which was higher than an average of 3.6 facilities for private clinics (p<0.05). Of 160 healthcare institutions, only 13 (8.1%) offered easy access to the outpatient setting from the entrance for wheelchair users, highlighting difficult wheelchair access within hospitals. To provide easy access to medical service for the disabled, more accessible designs need to be adopted as part of the effort to improve public facilities for the disabled. Also, universal designs could be applied for newly constructed roads, structures and transportation vehicles to maximize accessibility for the disabled. Increased accessibility for the disabled in the community will eventually increase the use of healthcare institutions.

This study shows the result of the survey conducted for male adults who had to use wheelchairs. The objectives of this study are to develop and improve the clothes for the disabled people and to make those garments put into practice. For this purpose, the survey was conducted at first so as to understand the situation of the disabled peoples wearing clothes and the garment demands. This survey is to suggest the suited form of the pants they want. The result of the study is as follows. 1) The average age of the subjects was 38.4 years old. They have used wheelchairs for 12 years on the average. Most subjects two limbs were paralyzed because of the acquired spinal paralysis. 60 percent of them were wearing the urine bags all the time. The average size of the pants they purchased was 39 inches, which means that their waist and abdominal circumstance were very big. 2) Regarding the situation of wearing habits, although the subjects usually purchased ready-to-wear, most of them are very dissatisfied with them. Especially, they considered the size as their main dissatisfaction. The main concern for buying garments was how comfortable and mobile they are while wearing them. They also needed outdoor garments. Lastly, they looked forward to the shop specialized in the garments for disabled people. 3) The functional pants for adult men using wheelchairs had the same zipper as that of general pants. The waist belt was made of rubber to reduce the pressure on waist and to cover 2 inches (5 cm) of waist circumference. Also it should be made to secure each button within the belt in accordance with size. Finally, it was designed as formal wrinkled pants that had pockets within the reach of hands when the disabled used wheelchairs.

Objective: The current study aimed to investigate the accessibility and usability of the disabled person while using the everyday facility. Background: The national laws regulated accommodation of persons with disabilities, but our knowledge on the practical usefulness of the laws and acceptance by the users is still far from complete. Method: Compliance with laws was checked throughout the actual measurement of 87 engineering designs in the facilities of a national university, and the practical usability of the facilities was investigated by in-depth interviews with eight disabled persons. New design solutions were developed by the anthropometric methodology for better accommodation. The target-specific anthropometry database such as sitting knee height with wheelchair was employed. Results: First, the statistic showed that 28.7% of facility designs comply with the law, 29.9% of facility designs doesn't comply with the law, and 41.4% of facility designs doesn't have related law or regulation. Second, the law of table height(71cm in current) can accommodate only 49.3% of wheelchaired population. The following test for 95% accommodation revealed that the table with 80cm high is required. Third, the current law in the door width(90cm) can only accommodate 82.6% of disabled persons, so the new design solution was calculated and suggested that 100cm in the door width is necessary for 99% accommodation of disabled persons. Conclusion: Even with the laws and regulations for the disabilities it was clear that the accessibility and usability of the disabled persons in everyday facilities was still limited. An investigation for the new solutions about a wide range of facilities is necessary for better practical accessibility and usability of the handicapped persons. Application: The results of current study can be a basement of developing a new guideline or regulation of the facility design for the disabled persons.

In this paper, we propose the Autonomous Stair-climbing system based on data from ToF sensors and IMU in developing stair-climbing robots to passive wheelchair users. Autonomous stair-climbing system are controlled by separating the timing of landing gear operation by location and utilizing state machines. To prove the theory, we construct and experiment with standard model stairs. Through an experiment to get the Attack angle, the average error of operating landing gear was 2.19% and the average error of the Attack angle was 2.78%, and the step division and status transition of the autonomous stair-climbing system were verified. As a result, the performance of the proposed techniques will reduce constraints of transportation handicapped.

Rehabilitation sports center is one of the sports center for the disabled that offers and operates programs to live with ordinary people through activities including various sports. This center must offer an environment that users be able to lead an sports activity by a removing physical and psychological obstacle. But most centers get in trouble using facilities that are so excessive or partly negative. Because, this center is offering a physical environment that absents correct comprehension of a standard plan and circulations of disabled. To takes part in physical exercise programs actively and encourages living sports activities, this study, will analyze circulations of disabled in accommodation and propose considerations at planning of rehabilitation sports center.

Purpose: The manoeuvring space at doors must be secured for users of walking aids, wheelchair users, stroller users, luggage carriers, etc., so clear criteria must be established. The korean standards for the manoeuvring space at doors need to be improved to present clear criteria depending on the type of entrance and the direction of opening and closing. Method: Korean standard, International Standard(ISO 21542, 2011), German Standard(DIN 18040-1, 2010), Austrian Standard(OENORM B 1600, 2017) and Swiss Standard(Norm SIA 500, 2009) were investigated and analyzed. A comprehensive improvement of the criteria for the manoeuvring space at doors is proposed. Results: The manoeuvring space at doors, which is essential for the disabled to use the door, shall be installed with a comprehensive consideration of the width of doors, the Circulation space, the direction of access, and the method of opening and closing of the door. Korean standards, such as the width of doors, the Circulation space, and the manoeuvring space at doors, are different from international and international standards, which require improvement of standards. The criteria for the manoeuvring space at doors shall be clearly improved so as not to be misinterpreted during the installation of doors and the BF-certification. Implication: The criteria for the installation of doors shall be presented as a comprehensive alternative through continued study of details. In addition, improvements in standards that reflect changes in international standards should be made.
