본 연구는 집중력, 기억력 및 학습 능력의 뇌기능 증진을 위한 의식적인 손 운동에 관련된 연구이다. 우선 효과적인 재활을 위한 손가락 운동 패턴을 연구하였다. 단순한 손가락 운동(Simple Finger Movement ; SFM) 패턴과 의식적인 손가락 운동(Intentional Finger Movement ; IFM)패턴을 비교하였다. 다음으로 각각 두 패턴 운동을 시켜 피험자의 집중력과 학습 능력의 증진을 검증하고자 한다. SFM 패턴과 IFM 패턴의 비교와 집중력과 학습 능력의 증진의 검증은 뇌파(mid α파)를 이용하였다. 실험은 먼저 SFM 패턴의 운동을 시키고 다음에 IFM 패턴의 운동을 시키는 실험을 하였다. 결과적으로 IFM 패턴에서 mid α파의 증가가 이루어졌음을 측정함으로써, IFM 패턴이 뇌의 집중력과 학습 능력을 증진시킨다는 결과를 얻었다.

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.

The purpose of this study was to analyze the pattern of muscle usage during swing motion with a soft golf club in comparison with that with a normal golf club. The subjects were normal healthy young adults. The subjects performed swing motion using normal and soft golf clubs in turn. Then, we compared and analyzed the muscular activities for the two cases. The muscular activities of the subject was measured using MP100(BIOPAC Systems, Inc.). For the analysis of muscular activities, we measured EMG(Electromyography) of the subjects during swing motion. The muscles analyzed were deltoid, latissimus dorsi, external oblique, and rectus abdominis of the upper limbs and rectus femoris, biceps femoris, gastrocnemius, and soleus of the lower limbs. The result of the experiment showed that the pattern of muscle usage with soft golf club was similar to that with a normal golf club but the muscular activities with the soft golf was smaller than that with the normal golf club.

The purpose of this study was to identify the characteristics of muscular power by COP(center of pressure) training according to the angle variation of tilting bed. We changed the angles of tilting bed(up-down direction 0°, 15°, 30°, 45° and right-left direction -15°, 0°, +15°) for the correlation between angles and muscular power. And we measured EMG(electormyography) of lower limbs muscle(rectus femoris, biceps femoris, and gastrocnemius, tibialisa anterior) during COP training. COP training was divided by the COP trace training(in all direction) and sine wave trace training(vertical and horizontal direction). As the result, we obtained the improvement effect of COP training and we showed that electromyography(EMG) variations of lower limbs muscle on the angle variations of tilting bed were investigated.

The purpose of this study is to experimentally analyze swing motion with soft golf clubs and compare with that with normal golf clubs. Soft golf is newly devised recreational sport based on golf but focus on the playability for the elderly. The subject for the experiment performed swing motion using a normal golf club and a soft golf club in turn. The swing motion of the subjects was tracked using an opto-electric three-dimensional motion analysis system. The results were compared against those obtained with a normal golf club. The range of motion was analyzed along with top head speed for two cases. It was found that higher club head speed could be achieved with reduced range of motion at lumbar joint using soft golf club when compared against the swing using regular club. The lower range of motion for lumbar bending means reduced risk of injury at the joint. So, it is projected that we can reduce the risk of injury with soft golf while maintaining the club head speed.
