초록

Korean Academy of Medical Sciences began developing Korean Medi cal CitatonIndex(KoMCI) database in 2002, and has announced the impact fac tors of Korean medicaljournals published since 2000. In July 2005, Korea Research Fou ndation also announced theKCI impact factor of journals covering all subject areas for th e year 2003 and 2004. Wecompared the impact factor(IF), impact factor excluding self-ci tation(ZIF), and self-citationimpact factor(SIF) of KoMCI 2004 and KCI 2004 in order to discl ose why there is such agreat difference in the values of impact factors between two da tabases. Out of 72 medicaljournals in both database, 59 journals were compared after excl uding the missing data inKCI. Mean IF of KoMCI 2004 was 0.2 and that of KCI 2004 was 0.0 3(p=0.0000). MeanZIF of KoMCI was 0.06 and that of KCI was 0.01(p=0.000). Mean S IF of KoMCI was0.139 and that of KCI was 0.02(p=0.0000). We presumed that the major difference in theimpact factor values was originated from the fact that KCI does not control the authority ofjournal names cited in the references. We strongly recommend that it is necessary to control the autho rity especially if KoreaResearch Foundation wants to ensure the validity and reliabilit y of KCI data in theevaluation of korean journals.
