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.

This study investigated the degree of inconvenience in existing ready-made clothes and clothing preferences through a survey of 197 wheelchair-bound males in order to provide preliminary data for the development of a suit that considers the physical characteristics and requirements of the disabled in wheelchairs for improved quality of living and positive interpersonal relations. Among the survey respondents, the 30s to 40s age group was the largest at 71.6%. The most common type of disability was myelopathy at 72.6%. Also 59.9% of respondents had a job and ongoing external and social activities. As for the duration of wheelchair use, 10-20 years was the longest at 40.6%. It was found from the survey that respondents felt inconvenienced with existing clothes and changing pants was most inconvenient. Most experienced having their clothes altered due to the difficulty in finding well-fitting ones; consequently, the length of pants was the most altered item because pants are based on the size of a standing man and there exists a discrepancy in length due to the atrophy of the legs of the disabled. They preferred one style in general for clothing preferences as well as common design and details as well. However, they preferred a style with a short front and long back due to a discomfort in jacket length. A short length was the most complained about pants item.

The wheelchair mechanism for a car that is proposed in this study primarily consists of a transfer mechanism and storage mechanism. The wheelchair transfer mechanism consists of a manipulator installed in the roof of a car, and performs the function of transferring the wheelchair from the driver's seat to the trunk. The wheelchair storage mechanism consists of a lifting hoist installed in the trunk of car, and performs the function of storing the transferred wheelchair in the trunk and safely fastening it in place. This study analyzed and reviewed various manipulators, including a vertical type, Scara type, and telescopic type, with the goal of selecting the best type of manipulator for the wheelchair transfer mechanism. The telescopic type was selected and applied because of its good load support and storage capabilities. In addition, with regard to the wheelchair storage mechanism, a slide hoist type that used a slide rail and lift wire and a rotating link hoist type that used a rotating mechanism consisting of a worm gear and link were analyzed and reviewed. The slide hoist type was selected and applied because it had an advantage in relation to trunk space utilization. This study proposed a wheelchair transfer mechanism for a car to support a conventional wheelchair user's movements, and in order to conform to the structure of a domestic welfare car for the disabled.

Generally, rural housing in Korea have had target of people who are in good physical health rather than the disabled. Therefore, it is difficult to offer high quality residential environment for the elderly and the disabled. The purpose of this study is to present the remodeling of rural house for the disabled. this study divides the a rural house into 7 sectors : a passage to entrance, an entrance hall, a livingroom, a bedroom, a bathroom, a kitchen, and etc. this study propose the following renovation plan that rural housing to be barrier free space. First, in passage to entrance of the house, people with disabilities should not experience difficulties in walking, so installing ramps to remove the stepped slope grade without slip so that the floor finish should be. Second, install grab handle on the wall inside the housing so that the disabled can lean on the handle. Third, placing the furniture in the bedroom that wheelchair can be rotated, and make to lower the height of the switchs. Forth, install a non-slip floor tile to prevent accidents in the bathroom.

The purpose of this study was to propose a functional improvement solution of integrated control board for safe driving of Smart electric wheelchair for a single person. In the case of existing electric wheelchair products in Korea and elsewhere, safety-related functions or devices are not included in many cases. Therefore, the incidence of electric wheelchair-related accidents is continuously increasing in the current situation in which the elderly and the disabled people have been continuously increased. However, currently only high and middle-priced products are equipped with basic safety devices in electric wheelchairs, so low-priced products require safety related functions. Therefore, sensing obstacles that the user can not recognize while moving an electric wheelchair and detecting automatically the terrain change to control the motor by developing a smart control platform. This provides an integrated control board that can be applied to various electric wheelchairs for more stable driving.

This study is to promote barrier-free environment to accommodate the request and the need for accessibility and convenience of disabled people including pregnant women, children and the elderly in using civic service offices which are supposed to play a role as community centers. This study researches the current state of facilities for convenience and analyzes the result according to the type of reasons which prevent disabled persons to get the accessibility and convenience for the information as well as the facilities. Sample cases are 15 civic service offices which are newly built after 1998 in the city of Daegu. There are found three types of problems about convenient facilities, which are the first cases with facilities not installed, the second cases with facilities not properly installed according to the rule, and the third cases with facilities installed properly according to the rule but inconvenient for the actual use. This study proposes a more critical process for the building permit to promote the rate of proper installation of convenience facilities, and the supplementary law with more specific regulations to improve the physical environment for the actual use of physically disabled people.

In this study, the process of providing information necessary to remove physical barriers such as road slopes that obstruct the activities of the disabled is in progress. Through experiments, we implement a quantified road surface roughness index that enables the implementation of IoT-based systems necessary for the elderly and the disabled to safely move to their destination. As a preliminary study, a road surface measurement device using a gyroscope was devised. To check the roughness and flatness of the road surface, X, Y displacement, and acceleration displacement were measured using a gyroscope. By calculating the measured data, the roughness and flatness of the road surface were quantified from 0 to 100. We implemented an algorithm that divides this index into 4 stages, displays it on a map, and provides it to users. Finally, a system for the disabled and elderly electric wheelchair users to secure basic mobility was established.
