Citation Analysis of The Korean Journal of Internal Medicine from KoMCI, Web of Science, and Scopus

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.

Korean Association of Medical Journal Editors (KAMJE) and the Current Status of KoreaMed and KoreaMed Synapse

The Korean Association of Medical Journal Editors (KAMJE) was founded in 1996. Among the 51 journals which participated in the founding of KAMJE, only 5 were listed in PubMed at the time, and none in Scientific Citation Index (SCI). In order to improve the quality of Korean medical journals, KAMJE established regular and systematic evaluation of medical journals, and has held academies for journal editors and education programs for manuscript editors. KAMJE has also focused on the database of Korean medical journals. KoreaMed, which provides access to articles published in Korean medical journals; KoMCI, which analyzes and provides citation data; and KoreaMed synapse, a digital archive and reference-linking platform. All of those are products of the efforts of KAMJE. By publishing "Good Publication Practice Guidelines for Medical Journals", KAMJE also has been focused on research and publication ethics. KAMJE has played an active part in establishing the Asia Pacific Association of Medical Journal Editors (APAME) and West Pacific Regional Index Medicus (WPRIM). Today, KAMJE, now composed of 188 journals covering medicine, nursing, dentistry, veterinary medicine, and nutrition, has 14 and 23 journals listed in PubMed and SCI, respectively. These achievements of KAMJE, attributable to the unrelenting efforts of Korean medical journal editors and editors, may be helpful in further improving the status of Korean medical journals.

Korean Medical Citation Index(KoMCI) and Journal of Korean Neurosurgical Society

The authority and reputation of a medical journal is based on the number of received citations. Korean Medical Citation Index (KoMCI) provides information about citations of Korean medical journals since 2002. All six issues of KoMCI (from 2000 to 2005) were used for analysis. Citations, impact factor, and their changes were evaluated. We compared the data of Journal of Korean Neurosurgical Society(JKNS) with other Korean medical journals. The impact factor(IF) of 2005 maintained increased value since 2004, although the impact factor excluding self citation(ZIF) returned previous low value. Improvement in proportion of Korean citations and in proportions of non-self received citations were encouraging changes. Although there were some improvements, the status of JKNS with respect to ZIF is still behind other Korean medical journals selected for comparison. Improvement of the status of JKNS by aid of KoMCI and enhanced reputation of KoMCI by its positive influence on JKNS or other Korean medical journals will be beneficial to members and medical societies of Korea.

Citation Trend and Suggestions for Improvement of Impact Factor of Journal of Korean Therapeutic Radiology and Oncology / 대한방사선종양학회지

PURPOSE: To analyze the recent citation trend and to find a way to improve impact factor (IF) of the Journal of Korean Therapeutic Radiology and Oncology (JKSTRO) by analysis of Korean Medical Citation Index (KoMCI) citation data of JKSTRO and comparison with that of mean citation data of all journals enlisted on KoMCI (KoMCI journals) during 2000-2005. MATERIALS AND METHODS: All citation data of entire journals enlisted on KoMCI and JKSTRO from 2000 to 2005 were obtained from KoMCI. The trend of total and annual number of published articles and reference citations, total citations and self-citations per paper, IF and impact factor excluding self-citations (ZIF) were described and compared on both KoMCI journals and JKSTRO. RESULTS: Annual number of published articles was decreased for 6 years on both KoMCI journals and JKSTRO (32% and 38% reduction rate). The number of Korean journal references per article is 1.6 papers on JKSTRO comparing to 2.0 papers on KoMCI journals. The percentage of Korean references/total references increased from 5.0% in 2000 to 7.7% in 2005 on JKSTRO and from 8.5% in 2000 to 10.1% on KoMCI journals. The number of total citations received/paper on JKSTRO (average 1.333) is smaller than that of KoMCI journals (average 1.694), there was an increased rate of 67% in 2005 comparing to 2000. The percentage of self-citations/total citations (average 72%) on JKSTRO is slightly higher than that of KoMCI journals (average 61%). IF of JKSTRO was gradually improved and 0.144, 0.125, 0.088, 0.107, 0.187, and 0.203 in 2000-2005 respectively. However, ZIF of JKSTRO is steadily decreased from 0.038 in 2000 to 0.013 in 2005 except 0.044 in 2004. CONCLUSION: IF of JKSTRO was slightly improved but had some innate problem of smaller number of citations received. To make JKSTRO as a highly cited journal, the awareness of academic status of JKSTRO and active participation of every member of JKSTRO including encouraging self-citations of papers published recent 2 years and submission of English written papers, and active academic cooperation with related academic societies.

Citations of Journal of Korean Neurosurgical Society Assessed by KoMCI-Trends in Recent Five Years

The authors analyzed the citation of Journal of Korean Neurosurgical Society, based on Korean Medical Citation Index(KoMCI) from 2000 to 2004. In this analysis the impact factor showed no significant further improvement in 2004 compared to 2003. However, the number of received citations was increased remarkably. If this increase can be kept up, it may have positive effect on impact factors. In the era of open competition of medical journals, the awareness and cooperations of every members of Korean Neurosurgical Society is essential for improvement of the status of our journal in a steady trend.

Citations of Journal of Korean Neurosurgical Society 2003: Analysis by KoMCI

The authors analyze the citation of Journal of Korean Neurosurgical Society, based on Korean Medical Citation Index(KoMCI) from 2000 to 2003. The impact factor of Journal of Korean Neurosurgical Society(JKNS) was 0.079 at 2000, and the score was below average among 69 KoMCI articles. The impact factor remained about the same value at 2001, 2002. However, it rised to 0.176 at 2003. This increase in citation was mostly by self-citation. Although the impact factor showed some improvement, yet it needs more time to conclude that the status of JKNS is in steady state of improvement. In order to make JKNS as a journal with high reputation and authority, the effort of every members of Korean Neurosurgical Society is essential.
