Abstract

BACKGROUND: The authors produced a new citation index of the Korean Journal of Blood Transfusion (KJBT). The index, which was developed to determine the internal impact score (IIS), could examine contributions to the KJBT according to the manuscript, author and institute.
METHODS
For manuscripts published in the KJBT from Volume 1 No. 1 in 1990 to Volume 17 No. 1 in 2006, a database of the journals and their references was constructed, and an index was created. The citation index was analyzed using three indicators, the internal impact score for the manuscript (IIS-M), internal impact score for the author (IIS-A) and the internal impact score for the institute (IIS-I).
RESULTS
The total number of references cited in the manuscripts was 5,392. Of these references, 498 (9.2%) were published in the KJBT. The mean IIS-M of all manuscripts cited was 0.97. The total number of authors who participated in the cited manuscripts was 351. The highest IIS-A score, which was calculated in consideration of each author's participation and the weight of the manuscript, was 203.26. The number of institutes that had produced the cited manuscripts was 35. The highest IIS-I score, which was calculated in consideration of each organization's participation and the weight of manuscripts, was 187.45.
CONCLUSION
If the indicators developed by the authors are used as tools to analyze the citation indices of the journals, they can quantify the contribution of the manuscripts, authors and institutes to each journal, and promote the development of academic journals based on the quantified contribution.
