In order to maintain a uniformity and consistency in terminology for constructing and searching a literature database, controlled vocabularies should be used as key words in the journal. While most of medical academic societies have recommended MeSH be used as key words, only 23 societies published terminology or index books. We reviewed 172 journals of JKOSMI published during the period from 1995 to 2000, using MeSH brower. Only 11.72% of key words were completely consistent with MeSH terminolgy and 25.56% were partially consistent. Purposes of this study are to examine a current status of using MeSH in the Journal of Korean Society of Medical Informatics(JKOSMI) and to develop a Korean terminology book on medical informatics
