BACKGROUND: Blood Research (formerly) was renamed 5 years ago. It aimed to identify the progress of the renamed journal at the international level based on journal metrics. METHODS: Journal metrics, including total cites, impact factor, and Hirsch index were calculated or found from Scopus, SCimago Journal & Country Rank, and Web of Science on March 27, 2018. RESULTS: The number of citable articles from 2013 to 2017 was 196, and that of non-citable articles was 157. The authors belonged to 25 countries. The editorial board members were from 33 countries. Total cites in Scimago Journal & Country Rank and Web of Science Core Collection in 2017 was 257 and 235, respectively. The cites per two years from Scimago Journal & Country Rank and the calculated impact factor from Web of Science Core Collection in 2016 were 1.353 and 1.382, respectively. The number of citing authors' countries in Web of Science Core Collection was 61. The number of citing journals in Web of Science Core Collection was 422. In 2016, the Hirsch index was 12 for Scimago Journal & Country Rank, and that in Web of Science Core Collection was 10. CONCLUSION: Since the title change, Blood Research has progressed rapidly on the international scene in terms of journal metrics. In particular, the results of total cites, impact factor, and Hirsch index were outstanding. This will enable its promotion as a high branded journal in the hematology category.

Objective: The aim of this study was to assess research productivity on preterm birth (PTB) in Southeast Asian (SEA) countries and its correlation with socioeconomic characteristics and burden of disease. Methods: A systematic review of preterm birth publications by SEA authors indexed in Scopus, PubMed, ClinicalTrials. gov, and Cochrane was done. Case reports, cohorts, control trials, reviews and cost analysis studies done by SEA researches involving pathophysiology, diagnosis, management, and complications of preterm birth was included in the study while published letters to editors were excluded. The correlation of bibliometric indices, namely Scopus citations, and PlumX metrics indices (citations, usage, captures, mentions, and social media), with socioeconomic status and burden of preterm birth in SEA countries were analyzed by computing for the correlation coefficient (r) and p-value at an alpha of 0.05. Results: Thailand had the highest number of publications and the highest count across all bibliometric indices among all countries in SEA. The percent gross domestic product (GDP) per capita allotted for research and development (R & D) had direct correlation with publications and captures while crude birth rates had indirect correlation with publications, citations, and captures. Neonatal mortality had indirect correlation with publications and captures. Conclusion Support for research and development is essential to increase research productivity in SEA, which in turn may help in finding solutions to decrease the rate of preterm birth in the region.

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.

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.

PURPOSE: The aim was to verify if changing the Journal of Gastric Cancer (JGC) to only English (starting in December 2010) was successful based on bibliometrics. MATERIALS AND METHODS: The following indicators were retrieved or calculated from the journal homepage and the Web of Science Core Collection on January 30, 2016: the number of citable articles per year; the number of original articles funded; the national origins of the editorial board members and authors; the total citations; the impact factors; the national origins of authors citing the journal; the source titles of articles citing the journal; and the Hirsch index. RESULTS: From 2011 to 2015, the number of citable articles per year was 40, 41, 39, 39, and 40. The proportion of original articles funded was 39 out of 113 articles (34.5%). The editorial board members were from seven countries. The authors were from 11 countries. The total citations increased from 1 in 2011 to 245 in 2015. From 2013 to 2015, the impact factors (without self-citations) were 1.42, 1.36, and 1.60. In 2014, the value 1.60 corresponded to the ranking of 157 out of 210 oncology journals (74.8%); It was cited from 46 countries. Top-ranking countries of citing authors were China (171), Korea (158), and Japan (75). The number of source titles citing the journal was more than 100. The Hirsch index was 12. CONCLUSIONS: The English-only language policy, which started in December 2010, was successful in promoting the JGC to international levels from the perspective of bibliometric analysis.

AIMThe situation of four Chinese core journals of physiology was summarized. The article also analyzed the deficiency of the periodical in order to provide better service for readers.

METHODSLiterature metrology method was used to analyze the published papers and cited papers carried in four Chinese core journals of physiology.

RESULTSThe quantity of published papers in Chinese journal of Applied Physiology was higher than that in Acta Physiologica Sinica and Progress in Physiological Sciences but was lower than that in Chinese Journal of Pathophysiology. In 2006, the funding ratio was 61.6%, but was lower than the others'. The impact factor assumed the increasing tendency, but was still lower than the others'. The paper's number and total frequency in periodical which was quoted, was as much as Acta Physiologica Sinica and Progress in Physiological Sciences, but was lower than those in Chinese Journal of Pathophysiology. The rate of high frequency paper quoted was 50%, was higher than the others'.

CONCLUSIONThe Chinese Journal of Applied Physiology has obtained some achievement since publication, but we also find the distance of funding ratio and impact factor compared with other congeneric journals. In summary, we shall try our best to make progress.
