We developed electric wheelchair INMEL-VI which is motorized wheelchair for practical use. The field test results of long time show some problems to disabled in daily use. INMEL-VII is designed to solve the problems of INMEL-VI and to adjust condition by the Korean Industrial Standards about the motorized wheelchair. Especially, it is improved to have durability, driving safety, and convenience of manipulating. In the driving field test in indoors and outdoors, it has been estimated to have a high practical use for powered walking aids to disable's daily life.

In this paper, the wall follwing method of a motorized wheelchair is discussed. The wall fellowing problem is characterized by maintaining a constant distance to the wall, which should be possible using a distance measuring sensor only. Ultrasonic sensors are cheap are fairly simple to use in this case. The main problem is the calculation of the distance and orientation of the wheelchair with respect the wall from the sensor data. This is solved by the method that sensor data is obtained from 3 ultrasonic sensors arranged at a same perpendicular pivot. The results show that a new method is very effiecient for a motorized wheelchair.

This research is to anticipate problems of Ray's disabled experiment welfare vehicles for 17 drivers with disability, improving them. In addition it is to provide the criteria for ergonomic design based on perspective of drivers with disability by investigating 18 items of usability test. The results are as follows. First, satisfaction degree of Ray, disabled experiment welfare vehicle, was shown to be 3.88 which is higher than normal vehicles whose degree is 3.20. This showed that the disabled experiment welfare vehicle is the one with much improvement. Second, so as to develop a welfare vehicle it needs to take into account some factors including rear slope, wheelchair locker, seat belt, safety grip, and high roof. Third, in case of rear slope, high roof and width of manual or automatic wheel chairs should be considered and motor-operated device should also be taken into account for safety lockers, which make a wheelchair firmly fixed. Moreover, motor-operated seat and rear slope can be chosen for either of the disabled and the elderly.

Accidents involving wheelchair accessible vehicles have been frequently occurring since the introduction of these vehicles in the Korean market. However, detailed regulations, which are required to ensure the safety of the wheel-chair occupants, are unavailable. In this study, both domestic and international vehicle safety regulations are analyzed in order to select the regulations that are similar to the transportation environment of Korea. Sled tests with an actual wheel-chair accessible vehicle were carried out based on the analyzed regulation requirements, as well as the values of the HIC, belt loads, dummy movements, and wheelchair movements. The test results showed that the movements of the dummy and the wheelchair did not meet the criteria of the regulation due to the improper positioning of the restraint systems.

For the disabled persons who can't use their limbs, motorized wheelchair that is activated by voice recognition module employing speaker independent method, was implemented. The wireless voice transfer device was designed and employed for the user convenience. And the wheelchair was designed to operate using voice and keypad by selection of the user because they can manipulate it using keypad if necessary. The speaker independent method was used as the voice recognition module in order that anyone can manipulate the wheelchair in case of assistance. Using the implemented wheelchair, performance and motion of the system was examined and it has over than 97% of voice recognition rate and proper movements.

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.

This study proposed an effective improvement direction for the education and welfare supporting facilities and equipment sectors to guarantee the right of disabled students to study in university. To derive high-demand items, the value engineering quality model technique was conducted on the students who majoring in architecture and the disabled students. The high-demand items for the education and welfare supporting facilities and equipment was detailed by interviews with the disabled students. Especially, anti-skid floor material, spacious access space for electric wheelchair, efficient operation system for elevator and cafeteria waiting time are strongly demanded for the disabled students. Based on this research, universities can make efficient investments and improvements in the education and welfare supporting facilities and equipment sectors for disabled students.

A properly prescribed wheelchair may be able to normalize tone. decrease pathologic reflex activity, improve postural symmetry, enhance range of movement, maintain and/or improve skin conduit)n. increase comfort and sitting tolerance, decrease fatigue, and improve function of the autonomic nervous system. Whereas a poorly prescribed one can actually exacerbate the problems associated with a disability. Maintained for longer without relief, pressure concentrations may also lead to tissue breakdown. Pressure sores continue to be a major problem for many disabled individuals. Many groups of disabled individuals have a very high incidence of pressure sores, including those individuals with spinal cord injuries. hemiplegia, multiple sclerosis. cancer. and the disabled geriatric population. It is important to understand the factors which predispose an individuals to the development of a pressure sores. Those factors can divided into extrinsic factors, related to the individual's immediate environment and intrinsic factors. related to their medical or physical condition. Pressure sores are generally preventable through sensible pressure management based on an understanding of the causes of pressure sores, risk factors and methods of redistributing pressure.

국제연합은 1975년에 "장애인 권리선언"을 결의하였고, 1981년을 "세계 장애인의 해"로 결정하였다. 우리나라에서도 1981년 6월 5일, 법률 제 3452호 "심신장애자 복지법"을 제정, 공포하였고 1989년 12월 30일 "장애인 복지법"으로 개정하였다. 한편, 미국에서는 1990년 7월 26일 George Bush 전 대통령이 "The American with Disabilities Act of 1990(ADA)"에 서명하였다. 이 법은 인종, 성별, 출신지, 그리고 종교에 관계없이 장애자에게도 같은 시민 권리 보호를 제공한다는 것이다. 그럼에도 불구하고 장애인을 위해 설계된 건물이나 시설물들이 그렇게 많지 않다는데 그 문제점이 있다. 따라서 본 연구의 목적은 신체 장애인에게 “동등한 생활의 질”을 제공하자는 데 있다. 그에 따른 목표로써 신체장애에 대한 구분이 이루어 졌고, 이동 수단으로서의 wheelchair에 대해 조사되었고, ADA accessibility guidelines가 분석되었다. 또한 인간공학과 감성공학으로 재활공학에 접근하였으며 가상현실이 이용되는 현 추세도 연구되었다. 결론적으로, 제시된 guidelines를 이용하여 가상현실의 세계에서 충분히 simulation을 마친 후에 장애인을 위한 좀더 과학적이고 합리적인 건물 또는 시설물 그리고 wheelchair를 제작할 수 있으면 한다.과학적이고 합리적인 건물 또는 시설물 그리고 wheelchair를 제작할 수 있으면 한다.
