The Comprehensive Assistive Technology services delivery was devised to describe the full social and engineering context of assistive technology devices, systems, applications, and provision. It is based on a detailed decomposition of the four attributes: Person, Context, Activities, and Assistive Technology. The paper commences will a brief discussion of the different representations of the services delivery, including rental of devices, modification of manufacture goods and customized production and the use of engineering to supplement some elements of the description. The main contribution of the paper is the presentation of two case studies of different applications of the assistive technology services. These are the identification of accessibility barriers, the analysis and synthesis of assistive technology systems and the provision of a framework for identitying end-user requirements, providing assistive technology and assessing the associated outcomes. This case study involves the presentation of the concept of a personal assistive technology profile.

This work proposes a new method to generate velocity profile of a traction motor equipped in a rehabilitation system for knee joint patients through humanoid robot simulation. To this end, a three-dimensional full-body humanoid robot model is newly constructed, and natural human gait is simulated by applying to it reference joint angle trajectories already published. Linear velocity is derived from distance data calculated between the positions of a thigh band and its traction motor at every sampling instance, which is a novel idea of this paper. The projection rule is employed to kinematically describe the humanoid robot because of its high efficiency and accuracy, and measured joint trajectories are used in simulating human natural gait referring to Winter's book. The attained motor velocity profile for a certain position in human body will be applied to our walking-assistance system which is implemented with a treadmill system.

The present study aims to examine the assistive technology service operation system[ATSOS] of the support system for independent living[SSIL] which was introduced after the enactment of the Law of Assisting the Independence for Persons with Disabilities[LAIPD] and to discuss its implications in the development of the assistive technology service delivery system[ATSDS] and the related measures for promoting the assistive technology industry in Korea. For this purpose, the literature review and the field study were employed. The research findings showed that the Japanese SSIL, which adopted the user payment system as measures to establish the sustainable ATSOS, arranged the consumer participation structure through substantial cooperation among related government departments. The result of this study indicates the need to secure the consumer's right to choose in a comprehensive utilization process of assistive technology services as for the establishment of the ATSDS in Korea. Furthermore, the arrangements for practical cooperative strategies among related government departments are encouraged.

This study is to suggest necessary improvements of inconvenient elements as well as the ergonomic design standard to develop disabled cars by evaluating the types of needs and observing the behavior characteristics on their car use and the survey on the complaints of the disabled drivers and their guardians in the use of disabled car. The results of this study are as follows. First, both the disabled drivers and their guardians are found to feel high inconvenience and low satisfaction with the cars they use now. Second, the disabled owner-drivers also answered in a same way as guardians. They find the most difficulty in moving the supporting equipment to get into and out of a car. Both the owner-drivers with disabilities and guardians complained of lack of handiness they face when they wear the seat belts and sitting on the seats. In view of this, a disabled car to be developed should have ergonomic design for its seats and the safety of the seatbelt as well as trouble-free supporting equipment helping them move. Third, rather than owner-drivers with handicaps, guardians expressed more difficulties and less contentment with the cars for the disabled, which is reckoned to lead to the changes of perspectives on development of cars for the disabled breaking away from existing viewpoints focusing on the accessibility to the vehicles. Fourth, both owner-drivers and guardians showed higher interests in driving and other safety and convenience measures than in using supporting equipment to get into and out of vehicles, implying that rather than the accessibility to get into and out of a car, convenience should primarily be taken into account for the design of the disabled car. Fifth, the auto-manufacturer is to give prior thought to user convenience when developing a car in practice. For this, the developer may have the disabled car users join the process of development as well as asking experts for help and participation.

In this study, an exoskeleton-type robot is developed to assist frozen shoulder rehabilitation in a systematic and efficient manner for humans. The developed robot has two main features. The first is a structural feature: this robot was designed to rehabilitate both shoulders of a patient, and the three axes of the shoulder meet at one point to generate human-like ball joint motions. The second is a functional feature that is divided into two rehabilitation modes: the first mode is a joint rehabilitation mode that helps to recover the shoulder's original range of motion by moving the patient's shoulder according to patterns obtained by motion capture, and the second mode is a muscle rehabilitation mode that strengthens the shoulder muscles by suitably resisting the patient's motion. Through these two modes, frozen shoulder rehabilitation can be performed systematically according to the patient's condition. The development procedure is described in detail.

현대사회와 미래사회는 가속화되어지는 IT기술에 의해서 융합되어진 작업의 효율 및 성능의 발전이 이슈화되고 있다. 따라서 1990년대부터는 군사 및 재활분야와 함께 제조업 및 유통업 등 전반적인 산업 모두에서 근력보조기구에 대한 연구가 활발히 진행되고 있다. 과거에는 일반인이 무거운 짐을 운반하는 것을 완전한 로봇이 대체하거나 몸이 불편한 사회적 약자가 휠체어 및 지팡이 또는 전동 휠체어와 같은 보조 개념이 아닌 완전한 대체의 개념을 가지고 있었다. 그러나 웨어러블이 대두됨에 따라 기계와 인체가 합쳐지는 상호작용 근력보조기구가 탄생했다. 근력보조기구는 힘/토크 센서를 통한 인간과 로봇간의 상호작용에 의해 인간의 다양한 상지 및 하지 동작을 구현할 수 있는 근력 강화용 웨어러블 로봇 등이 있다.

Objective : The purpose of this study was to investigate recognition and activation plan of community-based rehabilitation(CBR) by occupational therapists(OTs) in community rehabilitation center(CRC) and hospitals/clinics(HC) in Busan, Ulsan, and Gyeongnam province. Method : Frequency analysis, independent t-test and chi-squared test were performed with the SPSS 12.0 statistics package program. Result : CRC-OTs and HC-OTs were not significantly different in recognition was not significantly different in both groups. The need for involvement of OTs in CBR was very high in both groups. The suggested field for OTs in CBR were counseling for rehabilitation & information-providing, home-visiting rehabilitation, vocational rehabilitation, assistive device rental, education for disability prevention. It is required to establish CBR networking consisting of educational institutions for rehabilitation experts, local rehabilitation hospitals and clinics, and local government agencies as well as CRC and public health centers. Conclusion : CBR is recognized well by OTs in both CRC and HC and the involvement of OTs in CBR is highly needed by them. Activation plan for occupational therapy in CBR requires systemic and legal improvements.
