as higher education goes deep continuously, teaching method has become an important research topic of teaching theory in recent years. Multimedia teaching is one of methods in teaching system. On this basis, this paper develops and designs a multimedia teaching system which can achieve shooting and production at any time, and applies it to teach Martial Art course. Besides, computer technology is applied to design an operable system and construct multimedia teaching system for Martial Art course. Then, by example verification of students in Martial Art class of a college and statistical analysis of data, preliminary trial of multimedia teaching is achieved in practical application. Thus, this paper verifies that multimedia teaching system which can achieve shooting and production at any time can improve teaching quality, and further expounds the function and significance of multimedia teaching method from learning attitude and learning effect.

In order to simulate students’ enthusiasm in English listening and to improve teachers’ teaching efficiency, application of computer multimedia technology in English listening teaching has been wildly used. The purpose of this paper is to study the practical application of multimedia technology in English listening teaching. This study also also aims to improve the cognition of multimedia-assisted technology by exploring actual teaching cases. It will eliminate existing misunderstanding of assisting English listening teaching and improve the teach-ing effect of English listening. In this study we first elaborated the theoretical ba-sis of computer-assisted English listening teaching, and then clarified the teaching requirements of multimedia-assisted English listening teaching through question-naires. Finally, the effect of computer-assisted multimedia was evaluated through teaching comparative experiments. This study has important guiding significance in promoting diversified development of college English listening teaching and in developing students’ English listening ability and improving teachers’ teaching skills.

In our initial publication on this subject1) we reported results demonstrating that contrast is the most important factor in producing the high image quality required for reliable image analysis. We also listed the factors which enhance contrast in order of the experimentally determined magnitude of their effect. The two most powerful factors affecting image contrast attainable with sheet film are beam intensity and KV. At that time we had only qualitative evidence for the ranking of enhancing factors. Later we carried out the densitometric measurements which led to the results outlined below.Meaningful evaluations of the cause-effect relationships among the considerable number of variables in preparing EM negatives depend on doing things in a systematic way, varying only one parameter at a time. Unless otherwise noted, we adhered to the following procedure evolved during our comprehensive study:Philips EM-300; 30μ objective aperature; magnification 7000- 12000X, exposure time 1 second, anti-contamination device operating.

Abstract The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fifth Edition, is available and includes numerous changes that will affect both evaluators who and systems that use the AMA Guides. The Fifth Edition is nearly twice the size of its predecessor (613 pages vs 339 pages) and contains three additional chapters (the musculoskeletal system now is split into three chapters and the cardiovascular system into two). Table 1 shows how chapters in the Fifth Edition were reorganized from the Fourth Edition. In addition, each of the chapters is presented in a consistent format, as shown in Table 2. This article and subsequent issues of The Guides Newsletter will examine these changes, and the present discussion focuses on major revisions, particularly those in the first two chapters. (See Table 3 for a summary of the revisions to the musculoskeletal and pain chapters.) Chapter 1, Philosophy, Purpose, and Appropriate Use of the AMA Guides, emphasizes objective assessment necessitating a medical evaluation. Most impairment percentages in the Fifth Edition are unchanged from the Fourth because the majority of ratings currently are accepted, there is limited scientific data to support changes, and ratings should not be changed arbitrarily. Chapter 2, Practical Application of the AMA Guides, describes how to use the AMA Guides for consistent and reliable acquisition, analysis, communication, and utilization of medical information through a single set of standards.
