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.

본 논문은 현대에 신체활동(Physical activity)를 하지 않으면 심혈관계질환, 당뇨, 암, 골다공증 등과 같은 질환의 위험성을 가지고 있음에도 불구하고 공간부족, 시간부족, 날씨 등으로 제약을 받아 신체활동이 부족한 척수장애인의 들을 위한 스마트 휠체어 트레드밀을 개발함이다. 기존의 휠체어 트레드밀은 휠체어를 생활할 때 사용하는 대상자들에게 신체활동을 제공하였다. 스마트 휠체어 트레드밀은 경사(Slope-Incline, Decline)를 조절하여 개별마다 다른 건강체력능력에 운동강도(Exercise intensity)를 다르게 할 수 있다. 또한 스마트 휠체어 트레드밀은 거리측정, 속도측정이 가능한 센서를 부착하여 대상자의 운동량을 알 수 있을 뿐만 아니라 체중측정도 가능하여 대상자의 운동량에 대한 칼로리소모량을 얻을 수 있다. 이러한 스마트 휠체어 트레드밀과 VR(Virtual reality) 프로그램, 게임을 접목시켜 척수장애인들의 신체활동에 흥미를 증진 시킬 수 있다.

The purpose of this study is to figure out problems and to suggest improvement scheme by examining 31 of the disabled who used power wheelchair developed for safe moving and standing support. The results are as follows. First, standing power wheelchair that enables the disabled to sit and stand up was developed. It can also be used as means of transportation for moving in narrow space and in a short distance. In the usability test of this prototype, two groups were respectively examined in 60 evaluation items. One group consisted of 16 people with disabilities using manual wheelchairs. And the other one consisted of 15 people with disabilities using automatic wheelchairs. The entire average figure of two groups was shown to be 2.72 and standard deviation was 0.820. Specifically, the average figure of the group in manual wheelchair was 2.85 and the one of the other group in automatic wheelchair was 2.57. And both group replied that the move to stand up and sit on both types of wheelchair was the most inconvenient thing. It shows why ergonomic design for persons with under extremity disabilities to stand up and sit is needed. Second, with further study based on the results of usability test of the disabled, it will make contribution to increase the quality of people with disabilities by helping them move and do daily lives on their own.

등록 장애인의 수가 매년 증가함에 따라 휠체어 사용 장애인도 역시 증가하고 있으며, 이들은 일상생활에서 휠체어가 필수적이며 건축물 공간 내에서 수직이동을 위해 경사로도 필요하다. 휠체어 사용 장애인의 접근성 확보를 위한 수직이동시설 중 하나인 경사로의 경우 1/12라는 기울기로 인해 많은 공간을 차지하게 되므로 건축물 내 경사로 설치에 소극적으로 대처하고 있다. 기울기(1:12, 1:10, 1:8, 1:6)를 조절할 수 있는 경사로를 설치하여 20대, 30대, 40대, 50대, 60대 각 연령별로 남녀의 비율을 같게 하여 수동식 휠체어를 사용하여 이동 실험을 하였다. 화재와 같은 긴급피난 시 경사로 설치를 통해 계단으로 이동하지 못 하는 휠체어 사용 장애인들의 자력피난과 화재안전을 확보하고자 연구를 진행하였다.

In this paper, we compared wheelchair seating system between wheelchair users with cerebral palsy and spinal cord injuries. Wheelchair seating system is divided into three parts, seating components, seating cushion, and special functions. Seating components are composed of 10 sections, such as headrest, footrest, etc. There are 4 seating cushions including gel, form, hybrid, and air. Also leg elevation, seat elevation, tilt-in-space, reclining, and standing are special function of the wheelchair. There are 10 wheelchair users, 5 with celebral palsy, and 5 with spinal cord injuries who have participated in this study. 10 wheelchair users have been customers of rehabilitation technology center in national rehabilitation center. On the result, SCI group mostly uses headrest, and Humeral blocks (seating components), air cushion (seating cushion), and tilt in space, reclining (special functions). On the other hand, CP group uses adductor, abductor, and pommel (seating components), form cushion (seating cushion), and some of CP group uses reclining (special functions)

we suggest a shopping cart system following the wheelchairs autonomously for the disabled to do shop easily. This system have been developed in order for a cart to follow the disabled using wheelchairs automatically without pulling a cart directly. This system use kinnect and an radio control car (RC-car). The kinnect detect whether movement of disabled is right turn, left turn or straight and according to this result the RC-car can be controlled autonomously. By this system, the disabled using wheelchairs can do shopping more easily than before.

As Korea's per capita income increases, participation in various leisure activities to improve the quality of life of the disabled is encouraged. However, in order to participate in leisure activities, movement to the place where the leisure activities are performed must be preceded, so interest in means of transportation for leisure activities of the disabled is increasing. Since manual and electric wheelchairs have their respective disadvantages as means of transportation for leisure activities, interest in power assisting devices for wheelchairs combining the functions of electric wheelchairs with manual wheelchairs is increasing. In this study, the FDA approval process of wheelchair power-assistance products was investigated, and the characteristics of side-attached, front-attached, downward-attached, and rear-attached types of power assist devices for wheelchairs wheelchair in countries around the world were identified. These information will be of great use in helping the disabled and their assistants in Korea to choose the optimal product according to the patient's condition. More usability tests and clinical case studies are needed so that people with disabilities can choose a power assist device suitable for them.

Wheelchair users found difficulties in living independently in their houses due to the lack of accessibility. The state of the art smart home technology may enable wheelchair users to live independently. In this study, we built a smart home, and tested its usability with three community dwelling wheelchair users. Three evaluation methods such as scenario-based test, K-IADL(Korea instrumental activity of daily living) test, and in-depth interview were used. All three users responded positively for using the smart home. Through this study, we also found several necessary amendments in building smart homes for wheelchair users.

In this paper, when wheelchair user get into the vehicle, we have thorough grasp of the problems of loading wheelchair and give effect to suggest conceptual design in relation to develop manufactured goods. We choose 50 participants with disabilities who manual wheelchair or motor scooter users are able to drive own's vehicle, and the method practice in the direct survey. There are some limitations in this study especially in terms of the sampling population. The 88%(n=44) of the participant replied to the driver with disabilities need assistive devices for loading manual wheelchair. They prefer a system that robot arm brings the wheelchair out of the trunk to the driver's seat door.

연구의 목적은 지체장애인들의 신체적 특성을 고려하여 움직이기 편하면서 외관이 보기 좋은 기능성 의복을 제작하는데 있다. 휠체어, 크러치를 사용하는 여성 장애인을 대상으로 쟈켓, 바지, 휠체어 랩을 제작하여 외관상 기성복과 차이가 나지 않으면서 보조기구를 사용하는데 불편함이 없는 디자인을 제시하였다. 연구의 결과는 다음과 같다. 첫째, 휠체어사용자 쟈켓은 어깨와 팔의 동작을 쉽게 하기 위해서 뒤 bodice 소매둘레부위에 artion pleats를 주었으며 팔꿈치 부위에 주름으로 처리하여 당김과 움직임을 수월하게 하였다. 바지는 허리선 위치를 수정하고 굽혀져 있는 무릎부위에 앞은 주름, 뒤는 다아트로 처리하였다. 둘째, 크러치 사용자는 전체적으로 외관이 올라간 것처럼 보이는 것을 막기 위하여 쟈켓 길이를 길게 하고 쟈켓 위에 조끼를 덧입은 것처럼 보이게 하였다. 바지의 허리선은 고무벨트를 달았으며 양쪽 옆트임을 하여 지퍼를 달았다. 셋째, 휠체어 랩은 방수와 방한을 대비하여 만든 옷으로 전체적인 외관이 롱 원피스 형이며 발부위에 사각형 발판을 만들어 바람이 들어오지 못하도록 하였고, 양쪽 옆 지퍼를 사용하여 여밈 처리하였다.
