Study on physics Education at Premedical Course-Constructing Educational Data-Base(DB) for "Physics in Medical Sciences and Life Sciences"

在1990-1992年期间，我们建立了“医学与生命科学的物理”教育数据库。我们收集了放射学、核医学、生理学、超声医学、粒子束医学、医学工程等多个领域的数据。数据来源为1970-1992年出版的期刊、普通读者期刊、专著、书籍等。这些数据包括：主题、关键词(KW)、作者(S)、数据源(期刊或书籍、出版年份)、内容或摘要、参考文献等。我们组织了数据库，以便用户选择主题并搜索必要的文献。我们收录了60条指定领域的条目、150篇来自不同期刊的论文和100本相关书籍，在对KWS进行系统整理的过程中，我们选择了主要的分类领域，并编制了这些领域之间的相关方案，并编制了主题词表。为了检验数据库的教育意义，我们在医学专科学校的物理课堂上使用了数据库，第一节课的大约40名学生利用它来寻找研究主题。通过向数据库提供高达4千瓦的输入，用户可以轻松地搜索所需的数据。我们还利用数据库的优点，研究了数据库在教育领域和应用材料开发中的可能作用。每个作者都参与了这个研究项目：M.Hayashi主要负责开发主题和收集数据，K.Katsuura从事个人计算机软件相关的工作，A.Akabane从事教育含义的研究工作。

During the period of 1990-1992, we have constructed an educational DB for "Physics in Medical Sciences and Life Sciences". We have collected data from various fields, such as radiology, nuclear medicine, physiology, ultrasonic medicine, particle-beam medicine, medical engineering and others. The data sources are journals, periodicals for general readers, monographs, books and etc, published during 1970-1992. The data include the following items : theme, keywords(KW), author(s), data source(journal or book, year of publication), content or abstract, references and etc. We have organized the DB so that the users can choose a theme and search for necessary literature. We have recorded 60 items which specify fields, 150 papers from different journals and 100 relevant books.On making systematics for KWs, we have selected main categorical fields and have composed relevant scheme between these fields and have prepared thesaurus as well. In order to test the educational implication of the DB we applied it during physics lecture at our medical junior college, in which about 40 students of the first course made use of it to find research themes. One can easily search for necessary data by providing up to 4KWs as input to the DB. We have also investigated possible role of DB in educational fields and exploitation of applied materials by making use of the merits of DB.Each author participated in this research project as follows : M.Hayashi was responsible mainly for exploiting themes and collecting the data, K.Katsuura engaged in developing software related jobs for a personal computer and A.Akabane performed research work on educational implication.
