Twenty-one years have passed since PubMed Central (PMC) launched. The present case study describes Korean editors’ history of participation in PMC and their contributions to PMC. The three main turning points in the history of Korean editors’ involvement with PMC were as follows: first, the production of PMC XML files and deposition starting in 2008; second, thorough evaluations of applying journals since 2014; and third, the feasibility of non-English journals being indexed in PMC starting in 2019. The importance of PMC is further shown by the fact that KoreaMed Synapse, a full-text XML database of biomedical journals in Korea that was launched in 2007, was created by benchmarking PMC. Scholarly societies or institutes publish 724 (34.2%) of the 2,119 PMC journals without embargo in June 2021. Out of those 724 journals, 127 (17.5%) are published in Korea. PMC has helped local journals receive more citations from researchers worldwide, increasing their likelihood of being indexed in international databases. The number of submissions from international researchers has increased, thereby making it possible for journals to achieve international diversity. As the best full-text platform of biomedical journals, PMC has provided an excellent opportunity for biomedical journal editors in Korea to change their journals’ language to English and produce full-text JATS (Journal Article Tag Suite) XML files. These factors have made Korea the second-ranked country in terms of no-embargo PMC journals published by academic societies or institutes.

AbstractAbstract PDF
Purpose: This study aimed to compare the length limits specified in the author guidelines with the actual length of abstracts in 90 journals in the fields of pharmacology, oncology, and neurology. Specifically, the following parameters were examined: abstract formats among the three subject areas; the relationship between the length limit and the actual length of abstracts; and actual abstract length according to the number of subheadings, the length of structured abstract subheadings, the length of frequently used subheading sets, and clinical trial registration information.
Methods
Thirty journals from each of three medical fields (pharmacology, oncology, and neurology) were selected from Elsevier’s Scimago Journal Rank. This included the journals indexed in PubMed from 2018 to 2019 that published the most articles. Article abstracts from these journals were used to create a dataset for this study. Descriptive, comparative, and correlational analyses of data for the three fields were conducted.
Results
The number of subheadings and abstract length increased in parallel. The Results component was the longest, suggesting that authors tended to use longer text to report results than for other structural abstract components. Authors generally utilized the length limit to a full extent without exceeding it.
Conclusion
The traditionally used 250-word length limit should be reconsidered for pharmacology, oncology, and neurology journals because it disregards the distinctive characteristics of abstracts and length differences between structured and unstructured abstracts. Various characteristics of abstract lengths presented in this study should be considered to establish more justifiable policies.

AbstractAbstract PDF
In recent years, manuscript editing has become extremely important for academic journals. Using appropriate software for manuscript editing results in improved work efficiency and increased accuracy; therefore, this article aimed to introduce search engines and software that can be used for manuscript editing. First, a variety of search engines and academic databases can be used to reduce errors and to create accurate references. Google, the world’s leading search engine, provides users with information with the highest probability of accuracy, regardless of the reference language or the search term. If it is not possible to find certain information on Google, one can consult WorldCat, PubMed, Naver Academic, KoreaScience, Research Information Sharing Service, DBpia, Crossref, and Edifix. In particular, Naver Academic provides search results for some materials that cannot be found on Google. Second, PerfectIt facilitates the correction of errors that occur frequently in English-language documents. Finally, Grammarly is a helpful tool for checking and correcting grammar and spelling errors. As the academic publishing environment changes, the role and demands of manuscript editors are also changing. In a fast-paced environment, the software and search engines discussed herein are highly useful tools for manuscript editing.

AbstractAbstract PDF
This study compared the patterns of duplicate articles between KoreaMed and PubMed journals based on a division of duplicate publications into the 4 categories of ‘copy,’ ‘salami’ (fragmentation), ‘imalas’ (disaggregation), and ‘others,’ as well as in terms of the 11 subcategories suggested by Bae et al., which further elaborate on those 4 main categories. We hypothesized that these 2 groups of articles would show different patterns of duplication. Duplicate publications were identified in a random sample of 5% of the articles from the KoreaMed database published between 2004 and 2009, while all articles with the publication type of ‘duplicate publication’ were selected from PubMed over the same period. The selected articles were classified based on the 4 categories and 11 subcategories of duplicate publications, and the data from the 2 groups were compared. A total of 108 articles were selected from KoreaMed and 45 articles were obtained from PubMed. The category of copy was the most common in both databases. The next most frequent pattern was imalas (disaggregation). Pattern of duplicate publication between 2 databases showed no correlation (P = 0.8754). Although the 108 articles from KoreaMed were allocated to all 11 Bae et al.’s subcategories, those from PubMed were allocated to only 8. The above results showed that the articles in the 2 databases had different patterns of duplication, as defined in terms of the 11 subcategories. The use of these 11 subcategories will help journal editors to develop an appropriate framework for considering a variety of duplication types.

AbstractAbstract PDFSupplementary Material
This study aimed at analyzing the bibliometric characteristics and content of medical articles from North Korea in PubMed and characterizing the patterns of international cooperation of medical researchers in North Korea. We hypothesized that the number of publications from North Korea in PubMed has increased recently as a result of active cooperation with foreign researchers. PubMed was searched on July 19, 2017 using the search term “(North Korea [Affiliation]) OR Democratic People’s Republic of Korea [Affiliation]) OR DPRK [Affiliation].” The content of medical articles was analyzed and cooperative work with foreign researchers was noted. The number of medical articles in PubMed through July 2017 was 16, of which 2 were by North Korean authors only. From the content of these articles, it was found that researchers in top-notch institutions, including Kim Il Sung University, can access the internet, and that a dental caries prevention program supported by Finland has been in place for more than 10 years. The number of publications from North Korea in PubMed has increased recently, although the amount is still very small. Providing internet access to North Korean researchers will accelerate their submissions to international journals.

AbstractAbstract PDF
This year marked the twentieth anniversary of the Korean Association of Medical Journal Editors (KAMJE). The number of member journals has increased from 105 to 257 since its inception in 1996. In the same period, the number of journals listed in the Science Citation Index Expanded (SCIE) has increased from zero to 35. The average journal impact factor (JIF) that was initially 0.13 has now increased by more than tenfold on average to 1.45 as of 2014. Many KAMJE journals that are not indexed in the SCIE are putting their best effort towards eventual inclusion. Following listing with SCIE, however, editors have turned their attention towards the JIF and have shown interest in early online publication as a means of improving the JIF. The current status of PubMed electronic publication ahead of print (EAP) was surveyed among KAMJE journals that are indexed in the SCIE, and the impact of this EAP on the improvement of the JIF was investigated. Based on the survey, more than half of the members have started or are planning on implementing EAP. However, these efforts were found to be still in their infancy, and they have been insufficient to serve as a basis for scientific analysis. Since the sample size is too small and the implementation period too short to statistically analyze the effects of early publication on the JIF, a case-by-case approach was taken. Based on case studies, it is difficult to draw conclusions yet about whether online early publication enhances the JIF.

AbstractAbstract PDF

We hypothesized that it is not open access status but rather exposure in the PubMed platform that affects citation frequency in medical journals. In November 2008, medical journals from Korea began to be added to PubMed Central (PMC). Therefore, it would be interesting to know whether or not their impact factor based on Web of Science has increased since the journals were listed in PMC/PubMed. To answer this question, a citation analysis of seven journals that have been indexed in PMC since 2008 or 2009 was done. Only non-Medline journals were selected and the impact factors of five Medline journals were compared. The impact factor was calculated via Web of Science. Journal Citation Reports (JCR) data were used if the data of the target journals were provided in JCR. Trends for the impact factors of different years were analyzed using dBSTAT ver. 5.0. There has been an increasing rates of the impact factor for the seven non-Medline journals, 1.92 in 2011 over 2010; 3.27 in 2010 over 2009; 1.12 in 2012 over 2011. As for the five Medline journals, the increasing rate in 2010 over 2009 was 1.18; however, those of 2011 over 2010 and 2012 over 2011 were 1.01 and 1.04 respectively. The Science Citation Index Expanded impact factor of medical journals published in Korea can be increased if those journals are published in English and listed in PMC. This is an effect of the platform in which the journals are listed and not just an effect of free access.
