In previous studies, the dynamic exercise equipment just focused on the trunk stabilization exercise. However, our study is targeted at evaluation for the impact on the postural balance of those researches. Twelve male and twelve female subjects were volunteered for the balance training using this system. They had no medical history of backpain for the past six months. Trunk Stability and postural balance training was performed for 15 minutes a day, three times a week duing four weeks. To evaluate characterization of the postural balance using Balance System SD, Evaluation consist of the postural stability test and the postural limit test. As a result, this training with 3D dynamic exercise equipment help subjects improve the postural balance. These results are expected for using basic materials to the elderly with a high risk of falling and trained athletes needed to be a postural control.

The combination of developed medical devices and the convergence of IT fusion technologies, health variables became to can be measured without discomfort in everyday life regardless of wherever and whenever. because various types of u-Health medical devices have been developed. Also, by considering the users, biological signals can be measured without difference with wearing general clothing, that conductive fabric is being used as smart clothing. However, considering that there is a growing prevalence of the devices and a great interest in the development of u-Health devices, it is urgent to establish performance evaluation. Accordingly, writing guidelines by force to raise checking before marketed or collecting checks after at the market for standard test methods for evaluating the performance. In this paper, it was studied that the possibility of using conductive fabric as electrodes for Wearable u-Health Devices through the material test of the ffabric.

우리나라에서 노령화가 급속히 진행됨에 따라 근골격계(뼈 및 관절부분)의 기능 장애는 개인의 삶의 질을 심각하게 저하시킬 뿐만 아니라 개인 및 국가 경제에도 큰 손실을 초래하고 있다. 현재 국내에서 사용되고 있는 근 골격계의 재생/재건/재활 관련 의료기기 대부분은 수입에 의존하고 있다. 고가의 수입제품의 사용은 심각한 경제적 손실 뿐 만 아니라 환자의 의료비 부담에 따른 양질의 의료혜택에도 지장을 주고 있다.(중략)

It is Korea Employment Agency for the Disabled that is facilities providing assistive technology services for supported employment since 2004's. This center have one central organization and 18 branch offices. The need of this service through satisfaction research of the demand is confirmed by precedent study Therefore foundation of assistive technology center for supported employment should be required by demand analysis because of improving professional and providing 'qualitative' services instead of 'quantitative' ones. So assistive technology center for supported employment can resolve a problem about various needs for increasing disabled population. Demand of establishing this center has been researched.

Most Augmentative and Alternative Communication(AAC) use exclusive equipment or studied desktop, tablet PC based windows. Besides, the preceding study offers proper noun dictionary so, henceforward study has problem to innumerable proper noun processing. This paper suggests a method of proper noun processing using a mobile smart equipment. And via the button with virtual keyboard input method and the errors that can occur is also proposing a complementary way. AAC system to check availability for application on Android has been implemented. Experimental results, depending on user location and selection of proper nouns in the around could produce a sentence is derived.

The purpose of this study was to compare AAC service delivery system between Korea and U.S.A for appling effective 'AAC service delivery system. This delivery system complement the missing part in system of the current method and narrow blind area for system. The result of this research, increase suppling item of assistive communication device in public benefit and provide delivery system through construct infrastructure by assistive technology center, special education support center, developmental disorder support center, speech therapy center in each local area. Furthermore, assistive technology-related institute and academy develope training programs for human resources to delivery AAC service.

This paper describes the design and implementation of a rehabilitation medical device based on a EMG measurement. Rehabilitation systems are controlled using BLDC motors and motor drives. The BLDC motor drive controls the operation and the speed controls the drive through the external servo motor. In addition, potentiometer coupled to the outside of the motor transmits information about the position of the load being rotated by the motor. The rehabilitation algorithm is controlled by limiting the maximum angle of 0 to 120 by utilizing the motor according to the user setting stage during the rehabilitation exercise. The walking algorithm compensates motor control for the low leg of the signal using the difference value of the signal obtained with the surface denser attached to both inner muscles. The motor and surface denser are utilized for the walk motion to control the maximum angle of 0 to 80.
