Journal metrics-based position of diabetes & metabolism journal after the change of its text language to english

Abstract

After changing its language from Korean or English to English only in 2010, the journal metrics of Diabetes & Metabolism Journal (DMJ) were analyzed to assess whether this change in the journal policy was successful. The journal metric items that were analyzed were the following: impact factor; total citations; countries of authors; proportion of the articles funded out of the total number of original articles; and Hirsch-index (H-index). A retrospective, descriptive analysis was carried out using various databases, such as KoreaMed, Korean Medical Citation Index (KoMCI), KoreaMed Synapse, Web of Science, and Journal Citation Ranking. The journal's impact factor was 2.054, which corresponds to 83/122 (68.0%) out of the 2012 JCR endocrinology and metabolism category. The number of the journal's total citations was 330 in 2013. In addition to Korean authors, authors from 13 other countries published papers in the journal from 2010 to 2013. The number of funded papers from 2010 to 2013 was 65 out of 148 original articles (43.9%). The journal's H-index from KoreaMed Synapse was 7, and that from Web of Science was 9. It can be concluded that changing the journal's language to English was successful based on journal metrics. DMJ is currently positioned as an international journal based on the international diversity of authors and editors, its sufficiently high proportion of funded articles, its relatively high impact factor, and the number of total citations.
