본 연구는 뇌 질환 환자의 인지기능 재활을 위한 터치 패드 기반 응용 프로그램을 개발하는 것을 목표로 하고 있다. 터치 기반 장치의 상호 작용은 인지 치료에 쉽고 효과적인 교육을 제공 할 것으로 예상된다. 또한 터치 기반 모바일 장치의 이동성, 편의성과 다양한 기능은 데스크톱 기반의 유사한 전산화 치료 장치 이상의 교육의 연속성과 일관성을 증가 시킬 수 있을 것으로 기대된다. 5 가지 인지 영역은 대한 교육 내용은 관련 연구와 임상 가이드 라인을 토대로 선정된 5 개 인지 영역에 관한 훈련 콘텐츠를 제안하고 프로토타입 시스템을 개발하였다. 현재 3 주간의 파일럿 임상 연구가 진행 중이며 이를 통해 개발된 인지 재활 프로그램의 사용성과 임상 유효성을 검증할 계획이다. This study aims to develop a touchpad-based application for cognitive rehabilitation of brain-diseased patients. Touch-based interaction of the device is expected to provide easy and effective training of cognitive ability. Its greater mobility, convenience, and functional affordance over similar computational approaches based on desktop will increase the continuity and consistency of the training. Training content for 5 cognitive areas were developed based on concurrent researches and clinical guidelines. The prototyped rehabilitation program is under clinical trial test to ensure the clinical validity as well as the usability

This study proposes a human body orientation tracking system by inertial and earth magnetic sensors. These sensors were fused by indirect Kalman filter. The proposed tracking system was configured and the filter was implemented. The tracking performance was evaluated with static and dynamic tests. In static test, the sensor was fixed on the floor while its static characteristics was analyzed. In dynamic test, the sensor was held and moved manually for 30 seconds. The dynamic test included x, y, z axis rotations, and elbow flection/extension motions that mimic drinking. For these dynamic motions, the tracking angle error was under $4.1^{\circ}$ on average. The proposed tracking method is expected to be useful for various human body motion analysis.

Stroke is the second most significant disease leading to death in Korea. The conventional therapeutic approach is mainly based on physical training, however, it usually provides the limited degree of recovery of the normal brain function. The electric stimulation therapy is a novel and candidate approach with high potential for stroke recovery. The feasibility was validated by preliminary rat experiments in which the motor function was recovered up to 80% of the normal performance level. It is thought to improve the neural plasticity of the nerve tissues around the diseased area in the stroked brain. However, there are not so much research achievements in the electric stimulation for stroke recovery as for the Parkinson's disease or Epilepsy. This study aims at the developments of a wireless variable pulse generator using ZigBee communication for future implantation into human brain. ZigBee is widely used in wireless personal area network (WPAN) and home network applications due to its low power consumption and simplicity. The developed wireless pulse generator controlled by ZigBee can generate various electric stimulations without any distortion. The electric stimulation includes monophasic and biphasic pulse with the variation of shape parameters, which can affect the level of recovery. The developed system can be used for the telerehabilitation of stroke patient by remote control of brain stimulation via ZigBee and internet. Furthermore, the ZigBee connection used in this study provides the potential neural signal transmission method for the Brain-Machine Interface (BMI).

Stroke patients need regular medical treatments and rehabilitation training from their doctors. However, severe aftereffects caused by stroke allow them minimum activities, which make it difficult for them to visit doctor. Recently, electric brain stimulation treatment has been found to be better way compared to conventional ones and many are interested in using this method for the treatment of stroke. In this study, we have developed a remote medical treatment system using wireless electric brain stimulator that can help the stroke patients to get a treatment without visiting their doctors. The developed remote medical treatment system connects the doctors to the brain stimulator implanted in the patients via the internet and ZigBee communication built in the brain stimulator. Also, the system receives personal information of the connected patients and cumulates the total records of electric stimulation therapy in a database. Doctors can easily access the information for better treatment planning with the help of graphical visualization tools and management software. The developed remote medical treatment system can be applied to the electric stimulation treatments for other brain diseases with a minor change.

줄넘기 운동은 간단하면서도 매우 효과적인 운동 효과를 갖고 있지만, 높은 강도의 단조로운 운동 패턴으로 인해 지속적으로 운동을 수행하기 어려운 단점이 있다. 한편 줄넘기운동에 수반되는 운동에너지를 이용하여 전기에너지를 생성하는 것이 가능하며 이전 연구에서 이 그 가능성을 확인 하였다. 본 연구에서는 자가발전 줄넘기를 이용하여 사용자의 가속도 데이터를 스마트폰으로 전송하고 스마트 폰 App 에서는 전송 받은 데이터를 이용하여 사용자의 줄넘기 운동을 감지하고 계수하는 App 을 개발 하였다. 또한 실제 줄넘기 운동에서 활용되고 있고, 이미 그 효과가 입증된 음악줄넘기의 개념을 접목하여 리듬게임 형식의 스마트 폰App 콘텐츠를 개발하여 사용자에게 흥미 있고 다양한 줄넘기 운동 피드백을 제공할 수 있을 것으로 보인다. Jump-rope is a simple and effective exercise, but its intensive exercise load and monotonous pattern make it difficult to perform consistent workout. On the other hand, jumping rope accompanies large amount of kinetic energy which can be converted into electrical energy. In this study, we designed and implemented a self-powered jump-rope which can support the low-power embedded Bluetooth system inside it. The embedded system wirelessly transmits the acceleration data measured during jumping-rope exercise to smartphone. We also developed a smartphone app which can count the number of jumps and provide real-time feedback with sound and animated graphic effects in a game context. We expect that the developed self-powered jump-rope will make the intensive exercise into electricity-generating fun experience combined with smartphone game which gives real-time exercise feedback.

In this paper, we present the design of automated olfactory identification test system for mass screening, which is simple, rapid, accurate and low-cost. The automation is implemented by RFID (radio frequency identification) technology. The system consists of DI (user interface) system based on embedded computer, RFID reader system, odor samples and odor sample holder. A prototype is made according to the proposed design. The accuracy of the RFID reading is tested on the prototype. The feasibility is shown by olfactory threshold test and 16 odor identification test for 18 health subjects.
