In this study, changes of muscle activity that occurs when subjects walk or go up and down the stairs were analyzed by using EMG signal. The muscle activity of swing phase and stance phase was evaluated for each walking. Five healthy male capable of normal gait and stair climbing were selected as subjects. EMG signal from quadriceps and biceps femoris was measured. The stance phase was high during walking and the swing phase was high when subject go up the stairs, when subject go down the stairs, the stanse phase was high. Observations of muscle activity, stanse and swing phases were separated easily but kinds of gait were not separated. Through this study, appropriate EMG measurement part can be selected and recognition of stance and swing phased is possible using muscle activity when developing rehabilitation content for patients with transtibial amputation.

The ultrasonic image devices are very important device in making a diagnosis. In this system, the maintenance of the probe which have a direct effect to the image quality should perform thoroughly. For this reason, the periodical performance evaluation of probe should be achieve. Although the method for analysing an acoustic pressure distribution of acoustic field has good usefulness among the method for performance evaluation of probe, it has disadvantage that needs long time to get data. In this study, the automatic acoustic field scanning system was suggested for easy and fast scanning. It is controled the motor by 3 axis, and transmitted the PC data through the GPIB communication, and saved the peak to peak value by the signal processing in Pc. The scanning mode is consist of operate mode and measurement mode which is divided from 3D acoustic field scan mode and impulse measurement mode. Ultrasonic probe's scan time is measured by using the developed system and compared with hand-operate system. This system is abel to confirm that decreased of acoustic field scan time. it is conclude that auto scan system contribute to spread of performance evaluation of medical ultrasonic probe using acoustic field analysis.

문명의 발달과 함께 인간은 사회생활의 증가와 부족한 수면으로 인한 스트레스와 병이 증가하고 있다. 따라서 수면에 대한 관심이 증가하면서 편안하고 쾌적한 수면을 위한 수면환경에 대한 연구가 진행되어지고 있다. 본 연구는 쾌적한 온열환경 제시를 위한 방법으로서 여름철 실내환경이 수면에 미치는 영향을 알아보기 위해 22℃, 26℃, 30℃의 3가지 온도조건을 제시하고 5명의 피험자를 대상으로 수면다원검사를 실시하여 EEG, EOG, ECG, EMG 등의 생리신호를 측정하였다. 측정된 생리신호를 통해 수면단계분석과 수면효율을 분석한 결과 총 수면시간, SWS latency, 총 수면시간에 대한 SWS 시간의 비율이 26℃의 조건에서 가장 좋은 결과를 나타내었으며, 22℃, 30℃의 순서로 나타났다. 이러한 분석을 통해 온도차에 따라 수면상태가 달라짐을 관찰할 수 있었고, 여름철에 26℃ 정도의 실내온도가 편안하고 쾌적한 수면을 위한 실내온열환경임을 알 수 있었다.

Incontinence is the urination disorder as the leakage of urine without her own volition and the woman"s representative disease which reduces the quality of life. The urine incontinence has a problem that is hard to diagnosis and treatment because of a shame. The physiotherapy and behavioral therapy are the general method to treat the incontinence. But these methods have some week points such as dependence of individual volition and the troublesome for exam every visit to hospital. For these reasons, incontinence diagnosis system with pelvic floor muscle and EMG are suggested in this study. And the delivery system to therapeutic system and patient maintenance database base on the home network is also proposed. The proposed system is designed to minimized the other"s help with the self monitoring and treatment system by oneself. With the results of this study, urine incontinence patient can monitor and evaluate their state by oneself anywhere. And proposed system can lead the active participation to incontinence treatment.
