How far has The Korean Journal of Internal Medicine advanced in terms of journal metrics?

Abstract

The Korean Journal of Internal Medicine has already been valued as an international journal, according to a citation analysis in 2011. Now, 2 years later, I would like to confirm how much the Journal has advanced from the point of view of journal metrics by looking at the impact factor, cites per document (2 years), SCImago Journal Rank (SJR), and the Hirsch index. These were obtained from a variety of databases, such as the Korean Medical Citation Index, KoreaMed Synapse, Web of Science, JCR Web, and SCImago Journal & Country Rank. The manually calculated 2012 impact factor was 1.252 in the Web of Science, with a ranking of 70/151 (46.4%) in the category of general and internal medicine. Cites per documents (2 years) for 2012 was 1.619, with a ranking of 267/1,588 (16.8%) in the category of medicine (miscellaneous). The 2012 SJR was 0.464, with a ranking of 348/1,588 (21.9%) in the category of medicine (miscellaneous). The Hirsch index from KoreaMed Synapse, Web of Science, and SCImago Journal & Country Rank were 12, 15, and 19, respectively. In comparison with data from 2010, the values of all the journal metrics increased consistently. These results reflect favorably on the increased competency of editors and authors of The Korean Journal of Internal Medicine. © 2013 The Korean Association of Internal Medicine.
