How far has The Korean Journal of Internal Medicine advanced in terms of journal metrics?
허선 대한내과학회 2013 The Korean Journal of Internal Medicine Vol.28 No.6
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 (2years) 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 ref lect favorably on the increased competency of editors and authors of The Korean Journal of Internal Medicine.

허선 대한내과학회 2011 The Korean Journal of Internal Medicine Vol.26 No.1
The Korean Journal of Internal Medicine (KJIM) is the international journal published in English by the Korean Association of Internal Medicine. To understand the position of the journal in three different databases, the citation indicators were elucidated. From databases such as Korean Medical Citation Index (KoMCI), Web of Science, and Scopus, citation indicators such as the impact factor, SCImago journal rank (SJR), or Hirsch Index were calculated according to the year and the results were drawn. The KJIM 2010 impact factor increased to 0.623 in Web of Science. That of year 2009 in KoMCI was a 0.149. The 2009 SJR in Scopus was 0.073, with a ranking of 27/72 (37.5%) in the category of internal medicine and 414/1,618 (25.6%) in the category of medicine,miscellaneous. The Hirsch Index from KoMCI, Web of Science and Scopus were 5, 14, and 16, respectively. The KJIM is now cited more by international researchers than Korean researchers, indicating that the content of the journal is now valued at the international level.

Purpose: In April 2013, the journal metrics of the Korean Journal of Urology (KJU) were reported. That report showed tremendous improvement from the point of view of journal metrics. Two years later, the same metrics were reanalyzed to determine the present position of the KJU among the international journals in the Web of Science. Materials and Methods: I analyzed journal metrics of the KJU such as impact factor, total citations, and h-index by use of the same methods as in the previous report. Results: Total citations in the Web of Science were 332 in 2012, 439 in 2013, and 578 in 2014. Manually calculated impact factors from 2012 to 2014 were 0.770, 0.824, and 0.751, respectively. There was an increase in the h-index from 8 in 2012 to 11 in February 2015. Editorial board members were from 15 countries in 2014. Authors of KJU articles were from 21 countries in 2014. Conclusions: During 2 years, remarkable progress was made in KJU’s citation indicators and in the diversity of the authors’ and editorial board members’ countries.
