In this paper, an implantable middle ear hearing aids using an electromagnetic transducer which consists of a tiny coil and a magnet is designed, and objective design method to implement a vibrator of the electromagnetic type transducer is proposed. Sound characteristic of the electromagnetic type vibrator is excellent but power transfer rate is lower than that of a ceramic type. To improve power transfer efficiency of system, external and inner part of a middle ear system is designed using FI\T transmission method. We implemented an experimental set of the designed transducer, inner part, and outer part. Then, we measured vibration characteristics of a metal strip and a temporal bone of a dead body. As the results, we confirmed the advantage of FM method and showed that designed transducer could effectively transmit vibration of amplified input sound pressure to ossicle.

For use in the guide system for the people who are visually impaired, an obstacle searching device using synchronous ultrasonic wave emission was proposed and developed. Generally, the conventional obstacle detection methods use the ultrasonic distance measuring device with successive scan method. However, the scan method causes a theoretical error and it couldn't estimate accurate obstacle distances. The proposed synchronous firing method use the plural number of ultrasonic sensors which emit ultrasonic wave simultaneously and estimate the distance to the closest obstacle relatively accurately. We analytically analyzed the errors of the conventional and proposed methods and compared the quantitative differences of the errors. The differences verified by obstacle search experiments. Using the proposed ultrasonic wave synchronous firing method, 3 dimensional obstacle location estimating device was designed and implemented. The results of the 3 dimensional obstacle detecting experiments showed the proposed method had good performances and it would be sufficiently use in the guide system for the people who are visually impaired.

The purpose of this study was to investigate muscle activation of lower extremity such as rectus femoris, tibialis anterior and soleus according to 0cm(bare foot), 4cm and 7cm heel height of shoe on the rocking surface in older women. 20 older women who did not have any lower musculoskeletal and neurological disorders in the past were participated in this study. Each subject was standing for 15 seconds on the level 8 of Biodex Stability System (BSS) while wearing 4cm and 7cm heel height shoes including bare foot. Electromyography was used to measure muscle activation of lower extremity, and the muscle activation was expressed as a percentage of maximal voluntary isometric contraction (% MVIC). We measured % MVIC of three muscles during 5 seconds except for the first 5 seconds and last 5 seconds. SPSS 12.0 program was used for this study. Repeated one-way analysis of variance(ANOVA) was performed to compare the significant difference among the muscles of lower extremities according to heel heights of shoe on the rocking plate. % MVIC of each muscle such as rectus femoris, tibialis anterior and soleus regarding heel heights of shoe had statistically significant differences (p<0.05). The results of contrast test were as follows; 1) % MVIC of rectus femoris had significant differences between barefoot and 4cm, and barefoot and 7cm. 2) % MVIC of tibialis anterior had significant differences between barefoot and 4cm, barefoot and 7cm, and 4cm and 7cm. 3) % MVIC of soleus had significant differences between barefoot and 7cm, 4cm and 7cm. The results indicate that all commonly responsive muscle on the conditions of barefoot, 4cm, and 7cm shoe height on the rcoking surface is tibialis anterior muscle. We found out that the more heels of shoe high, the more muscle activation increases. High-heeled shoes above 7cm remarkably increase the muscle activation of lower extremity and may result in muscle fatigue. Thus, these shoes may summate risk factors of falls in older women. We can acknowledge that the heels above 4 cm affect each muscle activation in lower extremity on the rocking surface.

뇌졸중 환자들은 운동장애, 감각장애, 인지장애 등 다양한 후유증을 경험하게 되며 이를 극복하기 위하여 많은 재활훈련을 받게 된다. 이러한 재활훈련은 병원에서만 이루어 질 때 보다 일상 속에서 지속적으로 수행될 때 그 효과가 극대화 된다. 이를 위해서 다양한 가정용 훈련프로그램이 보급되었지만 이를 수행함에 있어서 적절한 피드백에 제공되어 지는 프로그램 부족한 실정이다. 따라서 본 연구에서 3차원 깊이 측정이 가능한 키넥트 센서를 이용하여 사용자에게 필요한 피드백을 제공 받을 수 있는 가정용 운동프로그램을 개발하고자 한다. 본 연구에서 제안된 프로그램은 사용자가 원할 때만 수행지식(knowledge of performance; KP) 피드백과 결과지식(knowledge of result; KR) 피드백을 선택적으로 제공하며 이러한 사용자 주도적인 선택적 피드백은 사용자의 운동효과를 극대화 시킬 것이다. Almost of stroke patients who experience aftereffects such as motor, sensory and cognitive disorders have to take some rehabilitation therapies. It is known that the consistent training for rehabilitation therapy in their home is more effective than rehabilitation therapy in hospital. A few home training programs were developed but these programs don"t give any appropriate feedback messages to the client. Therefore, we developed a home training program which can provide appropriate feedback message to the clients using the Kinect sensor which can analyze user"s 3-D dimensional motion. With this development, the client can obtain some feedback messages such as the knowledges of performance, results and self-controlled feedback. The program will be more effective than any existing programs.

최근까지 개발되었던 청각 보조기 중에서 공기 전도형 보청기의 하울링 (howling) 현상과 수술 후 이소골 등 기존 음향계의 재생이 불가능한 인공 와우 (cochlear implant system)의 단점을 해결하고, 동시에 청음 명료도가 높은 음성 신호를 전달하기 위한 수단으로 연구된 것이 인공중이 (implantable middle ear hearing device) 이다. 본 연구에서는 인공중이의 음성 신호 재현을 위한 진동 장치인 차동전자 트랜스듀서 (differential electromagnetic transducer, DET)에 대한 수학적 모형화와 계의 진동을 기술하는 운동방정식을 유도하고 그 해를 구하였다. 제한된 크기와 인가 전류 $1\;mA_{rms}$ 정현파에서 최대 구동력을 얻기 위해서 전자기력에 대한 유한요소해석을 수행하였고, 결과에 의해서 자석과 코일에 대한 최적 크기를 결정하였다. 사람의 중이 내 등자뼈 (stapes)의 진동 특성과 유사한 진동을 갖는 DET를 설계하기 위해서, 진동막의 강성계수를 변화하면서 진동해석을 시뮬레이션 하였다. 설계된 DET는 마이크로 머시닝 기술에 의해서 제작하였고, 그 진동 특성을 측정 하였다. 최종적으로 측정된 진동 특성에 대한 분석을 통하여 인공중이를 위한 진동 장치로서의 적용 가능함을 확인하였다. Among various kinds of hearing aids which have been developed so far. the conventional air conduction hearing aids have some problems such as the acoustic distortion, an howling effect due to acoustic feedback. Another type of hearing aid. the cochlear implant system can be applied to the profound imparied person. However. it shows the disadvantage that there is no possibility of recovery of the acoustic organ such as ossicle. On the other hand. the implantable middle ear heaving device directly vibratos the ossicular chain and has better sound qualify. good cosmetics for appearance. and wide frequency responses so that it can overcome the defects or the conventional hearing aids. In this paper, a mathematical modeling and a momentum equation derivation of the DET has been performed. For the optimization of the structure dimension generating maximal vibrating force of the DET. the computer simulation using a finite element analysis (FEA) software has been performed. Also. the vibrating transducer has been designed to make the frequency characteristics or the transducer be similar to those of the normal middle ear. Through the experimental results, the measured vibration characteristics of the DET has been evaluated to verify the performance for the application to implantable middle ear hearing devices.
