我々は,多様な動作が可能な5指ロボットハンドを用い,判別された筋動作とハンド動作とを対応付けることで,柔軟な対応能力を持つ筋電義手の開発を目指している.従来の研究では,筋電信号のWavelet解析結果に基づいて構築した判別空間上で,各動作のサンプル分布がPetal構造を成すことを示した.筋電義手利用者のQOLを高めるには,残った筋から得られる情報により,できるだけ多くの随意動作を判別可能にすることが望ましい.一方,装着の手間等を考えると,表面筋電計測位置は少ないほうがよい.そこで本稿では,Petal構造上でのクラスタ間の分離性評価により,判別可能な動作数の最大化と電極数の最小化とを図る手法を提案する.

<B>Background:</B> To provide oral healthcare for patients of all ages, dental welfare environments and technical aspects of dentistry have evolved and developed and dental education must also diversify. Student-centered voluntary education and establishment of a life-long self-learning environment are becoming increasingly important in the changing world of dental education. In this article, we introduce a new process for the construction of a web-mediated database containing internet-based teaching files on the normal radiological anatomy of panoramic radiographs and CT images of the oral and maxillofacial regions, as well as a system for the delivery of visual learning materials through an intra-faculty local network. This process was developed by our 5<SUP>th</SUP>-year undergraduate students.<BR><B>Methods:</B> Animated CT scan images were produced using Macintosh Iphoto and Imovie animation software. Normal anatomical images of panoramic radiographs and CT scans were produced using Adobe Illustrator CS and Adobe Photoshop CS. The web database was constructed using Macromedia Dreamweaver MX and Microsoft Internet Explorer. This project was the basis of our participation in the Student Clinician Research Program (SCRP).<BR><B>Results:</B> At Kyushu Dental College, we developed a new series of teaching files on the web. Uploading these teaching files to the internet allowed many individuals to access the information. Viewers can easily select the area of study that they wish to examine.<BR><B>Conclusions:</B> These processes suggest that our laboratory practice is a useful tool for promoting students' motivation and improving life-long self learning in dental radiology. We expect that many medical and dental students, practitioners and patients will be able to use our teaching files to learn about the normal radiological anatomy of the oral and maxillofacial regions.
