Welfare centers for disabled person which are typical facilities in Korea are classified into two catagories One is general welfare center for all type of disabled persons and the other is special welfare centers for special disabilities such as visually handicapped persons, hearing-impaired persons and the physically disabled. In this study the movements of disabled persons in daily lifes were measured and many evacuation drills in welfare centers were conducted for the achievement of basic data such as velocities and evacuation patterns of disabled persons The evacuation patterns are characterized by different kinds of disabilities.

본 논문에서는 지체장애인들이 유효한 말초신경신호를 이용하여 컴퓨터를 사용할 수 있는 인터페이스를 개발하였다. 손목의 움직임을 통해 아래팔 4부분으로부터 근전도 (electromyogram, EMG) 신호를 추출하였고, 다층 인식 신경망을 사용하여 사용자의 의도를 추출하였다. 이를 통하여 마우스 커서의 움직임을 제어하고, 마우스 버튼을 클릭하는 동작을 할 수 있으며, 시각 디스플레이 장치에 표시된 핸드폰 자판과 같은 유저 인터페이스를 통해 컴퓨터에 글자를 입력할 수 있게 하였다. 추가적으로 Fitts' law를 사용하여 본 인터페이스의 사용성을 평가하였고, 이를 기존연구와 비교함으로써 본 인터페이스의 효용성을 검증하였다.

This study attempted to develop a speech recognition module applied to a wheelchair for the physically handicapped. In the proposed speech recognition module, TMS320C32 was used as a main processor and Mel-Cepstrum 12 Order was applied to the pro-processor step to increase the recognition rate in a noisy environment. DTW (Dynamic Time Warping) was used and proven to be excellent output for the speaker-dependent recognition part. In order to utilize this algorithm more effectively, the reference data was compressed to 1/12 using vector quantization so as to decrease memory. In this paper, the necessary diverse technology (End-point detection, DMA processing, etc.) was managed so as to utilize the speech recognition system in real time

Knowledge of the anatomy and biomechanics of the knee is critical fur successful rehabilitation fellowing knee injury and surgery. Biomechanics of both the tibiofemoral and patellofemoral joints must be considered. The purpose of this paper is to provid framework for rehabilitation of the knee by reviewing the biomechanics of the tibiofemoral and patellofemoral joints. This will include discussion of the relevant arthrokinematics as well as the effects of open and closed chain exercises. The implications for rehabilitation of the knee will be highlighted.

This study for enquete an exact the present conditions museum plan for analyzing barrier free theory. The research is base on the side of consciousness, space and activity the present condition for person of an advanced age and the physically handicapped person. Through the research for purpose of confirm that baker free theory. And also, using for the result i]f this research that for all user. And then, it will be turn out that direct data linked to solve of the realistic subject, so therefore basic course and guide line what was due to point out

This study aims at discussing the future trend of the community bus and attempted to route selection by using GIS for the welfare-type community bus, which satisfies the need of elderly and physically handicapped persons in Nagasaki City. In doing so, we have conducted field survey in some sample cities of Kyushu, Japan for taking lessons from the present state analysis of community bus already operating there. As a result of the study, we have been able to identify some best possible routes for the community bus operation in Nagasaki City, which meets the requirement of the welfare community as well as of the general passengers.

This study was conducted with the purpose of examining the direct effect of daily life restrictions on the behavior of people with physical disabilities who are easily exposed to 'disaster inequality' on emergency behavior, and comprehensively examining the mediating effect of depression and residential environment in this relationship. For this purpose, a total of 803 persons with physical disabilities aged 20 years or older were analyzed among the panels of the second year(2019) of the Panel Survey for People with Disabilities. As a result of the analysis, first, the daily life restriction of the physically disabled had a positive(+) effect on depression, a negative(-) effect on the residential environment and emergency behavior and depression had a negative(-) effect on the emergency behavior. The residential environment had a positive(+) effect on behavior in case of emergency. Second, it was found that depression and residential environment had a mediating effect between daily life restrictions and emergency behavior of the physically handicapped. In other words, it suggests that the living environment and depression can play an important role in the effect of daily life restrictions on the behavior in case of an emergency. Based on the analysis results, the implications of the study were suggested.

BCI (Brain Computer Interface) is technology to control external devices by measuring the brain activity, such as electroencephalogram (EEG), so that handicapped people communicate with environment physically using the technology. Among them, EEG is widely used in various fields, especially robot agent control by using several signal response characteristics, such as P300, SSVEP (Steady-State Visually Evoked Potential) and motor imagery. However, in order to control the robot agent without any constraint and precisely, it should take advantage of not only a signal response characteristic, but also combination. In this paper, we try to use the fusion of motor imagery and P300 from EEG for practical use of robot control in BCI environment. The results of experiments are confirmed that the recognition rate decreases compared with the case of using one kind of features, whereas it is able to classify each both characteristics and the practical use technology based on mobile robot and wireless BCI measurement system is implemented.

As the seniors and the disabled has increased, the demand for cultural centers has also increased in many local areas. This means that the local cultural centers designed from the viewpoint of universal design are needed, so that to be used by everyone without any difficulties. This study examined the applicability of universal design principles to the public service areas of the local cultural centers. The subject cultural centers were three local ones which had seating capacity of more than 1,000 and opened after the year of 2,000 in Gyungnam. The spatial scopes of the study were six public service areas of the local cultural centers : entrance area, corridor and pathway, stair, ramp, elevator, and rest room. The total 65 items for evaluating the applicability of universal design were selected and examined for six areas. On the whole, accessibility, such as wide pathway and flat floor was good. However, the following improvements were needed. 1) Handrails and rounded corner were needed on walls. 2) Consideration of the visually impaired like as braille sign was needed. 3) The handrails on ramp should be installed for usability. 4) The automatic door would be more useful to the physically disabled users. 5) Wider space and familiar handrail design and color were needed in the rest rooms for the handicapped.
