This paper describes development of a hand and finger fixing system for the rehabilitation exercise of patient's fingers. In order to exercise the finger rehabilitation using a finger rehabilitation robot, a patient's hand or fingers are fixed safely. In this paper, The hand and fingers fixing system can safely fix stroke patient's hand and fingers by pressing with force control system. The characteristic test of the system was carried out. It is thought that the system could be used for fixing their fingers in stroke patient's finger rehabilitation exercise.

Objective : The purpose of this study was to look at a systematic review on the effects of robot-assisted therapy on stroke rehabilitation in upper limbs. Through this comprehensive study, we have to compare the studies. Methods : We systematically examined papers published in journal from June 2012 to September 2012, using EMBASE, MEDLINE, etc. 12 studies(randomized controlled trials) were included in the analyses. Results : Selected 12 studies were Pedro score 2 or more. The primary outcome measure tools including tools for upper extremity function and activities daily of living were used. Through various intervention, Robot-assisted therapy maximizes the effectiveness of intervention. The effects of upper extremity function and functional ability(ADL) by robot-assisted therapy showed significant effect, but no difference exists between the robot-assisted therapy and conventional therapy groups in terms of upper extremity function and functional ability. Conclusions : Robot-assisted therapy has been widely used clinically for stroke patients to maximize the effect had been applied to various interventions. Robot-assisted therapy depending on the methods of intervention showed that the effect of difference. In the future study, the use of robot-assisted therapy applied to a variety of interventions is needed on occupational therapy.

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.

Medical service robots are variously defined and classified by researchers and related government departments, but surgical robots and rehabilitation robots are commonly included in medical service robots, and except for these, the robots are classified as other medical service robots. In this study, domestic and foreign development trends and use cases were considered, focusing on logistics, guidance, and drug processing robots among other medical service robots. Logistics and guidance robots were developed quite a lot in Korea and completed a pilot project, or are being commercialized in hospitals, and exported. However, although the drug prcocessing robots was developed in Korea, the robot being use in the hospital was an imported. In order to expand and activate the robot market, systematic follow-up studies such as demand prediction studies are needed.

The system for controlling the robotic arm through the foot motion detection was implemented for the disabled who not free to use of the arm. In order to get an image on foot movement, two cameras were setup in front of both foot. After defining multiple regions of interest by using LabView-based Vision Assistant from acquired images, we could detect foot movement based on left/right and up/down edge detection within the left/right image area. After transferring control data which was obtained according to left/right and up/down edge detection numbers from two foot images of left/right sides through serial communication, control system was implemented to control 6-joint robotic arm into up/down and left/right direction by foot. As a result of experiment, we was able to get within 0.5 second reaction time and operational recognition rate of more 88%.

The purpose of this study was to investigate the effects of an increase in self - determination experience on the behavior of young children with autism spectrum disorder by telepresence robot. As for research method, the study used AB design, two selected children engaged in activities with a telepresence robot in free play time in the morning. The activities were conducted in 19 sessions, twice a week, 15 to 40 minutes each. To investigate the effect of the activity on the child's behavior was observed using the behaviors of free play time and work time in the afternoon. All the process was recorded by a camera and then analyzed by frequency recording. The results of the study are as follows. First, the participation of young children with autism spectrum disorder in free play time increased. Second, choice-making or preference behavior of young children with autistic spectrum disorder were increased. This study suggests that increasing the self-determination experience of young children with autism spectrum disorders using telepresence robots increases their participation and increases their choice-making or preference behavior.

This paper is the design for the welfare robot of apple artificial pollination by a survey for 25 elders' needs of Daegu-Gyeongbuk rural region. The results are summarized as follows. 1) In the apple farms of the region, most of farmers are the couples of 50 years thru 70 years to plant the apple trees only. The apple farm requires the senior farmers lots of painful works including their bone and muscle system problem to result in safety accidents. 2) For the aging progress of rural area, the senior farmers spend lots of labor hours and cost to do artificial pollination, a proper deletion of small fruits, and a speed spray, etc.. Most of them agree to the development of the welfare robot for an apple artificial pollination. 3) The survey results could be applied to the conceptual design in the users' point of view. Therefore, they are used as the important effects for the detail design and commercial design to develop the welfare robot for the rural seniors.
