BACKGROUND: Bibliometrics is increasingly used to assess the quantity and quality of scientific research output in many research fields worldwide. This study aims to update Korea's worldwide research productivity in the field of orthopedics using bibliometric methods and to provide Korean surgeons and researchers with insights into such research. METHODS: Articles published in the top 15 orthopedic journals between 2008 and 2017 were retrieved using the Web of Science. The number of articles, citations and h-index (Hirsch index), funding sources, institutions, and journal patterns were analyzed. RESULTS: Of the total 39,494 articles, Korea's contribution accounted for 5.6% (2,161 articles), ranking fifth in the world in the number of publications. Korea ranked sixth (with 29,456) for total citations worldwide but ranked 17th (13.64) in terms of average citation per item and 14th (55) in terms of h-index. Korea showed the most prolific productivity in the field of sports medicine and arthroscopy. The institution that produced the highest number of publications was Seoul National University (n = 386, 17.9%). CONCLUSIONS: Orthopedic research in South Korea demonstrated high productivity in terms of the number of publications in high-quality journals between 2008 and 2017. However, total citations and average citations per article were still relatively low. Efforts should be made to increase citation rates for further improvement in research productivity in the field of orthopedics.

OBJECTIVES: To analyze the literature on forensic sciences indexed in Science Citation Index Expanded （SCIE） in recent 10 years, and to understand the research status, characteristics and trends in the field of forensic sciences. METHODS: Literature on forensic sciences from 2008 to 2017 in Web of Science （WoS） was retrieved. The documents number and geographical distribution, document types, source titles, organizations, research areas, authors, funding agencies, and the high cited articles were detected. The impact factors （IF） of journals were retrieved in Journal Citation Reports （JCR）. The data were analyzed with descriptive statistics. RESULTS: From 2008 to 2017, there were 21 001 documents on forensic sciences in SCIE. The main document type was articles, with English as the major language. With regards to research areas, pathology has the largest number of papers worldwide, and genetics and heredity has the largest number of publications in mainland China. Among the 18 journals where the documents was published, Forensic Science International ranks the first on publication count, and Forensic Science International Genetics has the highest IF （5.637） in the JCR 2017. In 2017, the number of papers from mainland China increased by 48.50% compared with 2016, which was higher than the global increase （32.63%） and the top-5 countries in terms of number of publications （the US, Germany, the UK, Australia, Italy）. The average document count per organization is 1.98 worldwide and 1.17 in mainland China, respectively. The publication number per author is 0.53 worldwide and 0.36 in mainland China, respectively. Around 28.17% of the publications were funded, with National Natural Science Foundation of China （NSFC） as the Top 1 funding agency （192 papers）. Among the documents with citations, the most cited publication has been cited for 366 times. CONCLUSIONS The yearly numbers of publications on forensic sciences are increasing during recent 10 years. Focusing on the mainland China, there would be more high-quality papers with the steady funding of NSFC.

BACKGROUND: The prevalence, incidence, and mortality rates of tuberculosis (TB) have declined steadily in Korea since 1965. This study aimed to identify the characteristics and provide quantitative analysis of published medical literatures on TB written by researchers based in Korea. METHODS: We conducted a systematic literature search via the Web of Science database for articles in Science Citation Index (Expanded) journals, on TB, and published by researchers based in Korea, from inception to 2017. All articles were analyzed by publication year, publishing journal, article type, study design, research institutes, and research funds. RESULTS: During the study period, we identified 1,101 articles and included them for analysis. The first was published in 1979, while 105 were published in 2017. Between 1979 and 2017, the compound annual growth rate of TB articles by researchers based in Korea was 13.0%. Among 1,101 articles, 682 (61.9%) were clinical research and 383 (34.8%) were basic research. Studies with cross-sectional design were the most common type among the clinical research, while biochemistry was the most common field among the basic research. The number of articles dealing with diagnostics or treatment has increased significantly, although the number of articles on vaccines, and on operational and public health, has only a slight increase. The Ministry of Health and Welfare of Korea funded studies yielding 178 (20.1%) articles. CONCLUSION: Articles on TB, especially those on clinical aspects, and published by researchers based in Korea have been increasing rapidly since 1979.

OBJECTIVES: The aim of this study was to evaluate the journal category “oral surgery” in Scopus and in the Science Citation Index Expanded (SCIE). MATERIALS AND METHODS: The Journal of Oral and Maxillofacial Surgery (JOMS), The Journal of the Korean Association of Oral and Maxillofacial Surgeons (JKAOMS), and The Journal of Prosthodontic Research (JPR) were selected from the Scopus list of journals as oral surgery journals. Maxillofacial Plastic and Reconstructive Surgery (MPRS) was selected from PubMed as a Scopus oral surgery title. From these titles, 10 recently published articles were collected and used for reference analysis. RESULTS: The percentage of citations from oral surgery journals was 26.7%, 24.5%, and 40.1% for JKAOMS, MPRS, and JOMS, respectively. In total, 1.1% of JPR's citations were from oral surgery journals and significantly fewer from other journals (P<0.001). The percentage of citations from dentistry journals excluding oral surgery journals was 11.9%, 34.4%, and 15.8% for JKAOMS, MPRS, and JOMS, respectively. For JPR, 80.6% of citations were from dentistry journals and significantly more were from other journals (P<0.001). CONCLUSION: Selected samples revealed that JPR is incorrectly classified as an oral surgery journal in Scopus. In addition, the scientific interaction among JKAOMS, MPRS, and JOMS was different to JPR in the reference analysis.

OBJECTIVES: A citation analysis of biomedical and health sciences journals was conducted based on their enlistment in journal databases to identify the factors contributing to the citation metrics. METHODS: Among the 1,219 academic journals managed by the National Center for Medical Information and Knowledge at the Korea Centers for Disease Control and Prevention, 556 journals were included for analysis as of July 2016. The characteristics of the journals include history years, publication media, language, open-access policy as well as the status enlisted in international and domestic databases, such as Science Citation Index (SCI), Scopus, Medline, PubMed Central, Embase, and Korea Citation Index (KCI). Six bibliometric measures were collected from SCI, Scopus, and KCI as of 2015, the most recent disclosure year. Analyses of group differences and influential factors were conducted using t-tests, Mann-Whitney tests, and multiple regression. RESULTS: Journal characteristics, such as history years, publication media, and open-access policy, were not significant factors influencing global or domestical citation of the journals. However, global citations were higher for SCI and Medline enlisted journals than for their counterparts. Among KCI journals, the KCI impact factors of journals published in English only were lower. CONCLUSIONS: Efforts by journals to be enlisted in international databases, especially in SCI and Medline, are critical to enhance their global circulation. However, articles published in English only hinder the use of domestic researchers. Different strategies are required for enhancing international and domestic readerships.
