Scientific publication productivity of Korean medical colleges: an analysis of 1988-1999 MEDLINE papers

To identify where the quality research activity has been and is carried out in Korea, and to examine to what extents Korean medical colleges play leading roles in the production of international research papers, we investigated the publication productivity of Korean medical colleges and their medical departments as measured by the number of papers published in foreign journals indexed in MEDLINE. The 12-year period from 1988 to 1999 is covered. A total of 4,881 papers is published in MEDLINE foreign journals by the researchers in Korean medical colleges during the period. The production of MEDLINE papers are concentrated in a few universities. More than 60% of MEDLINE foreign journal papers is published by top five universities 25% by Seoul National University, and 15% by Yonsei University. The newly established medical colleges at the University of Ulsan and Sungkyunkwan University produced outstanding numbers of papers in less than ten years. Radiology has led the internationalization of Korean medical papers. It was the most productive specialty identified in this study. The productivity of Internal medicine is on the rise from the mid-1 990s, and the field began to produce the most number of papers since then.     

Progress and Prospect: A Bibliometric Analysis of Research Papers by Korean Allergists Over Recent Five Years (2009-2013)

Since the establishment of the academic society in 1972, Korean allergists have made continuous efforts to elucidate pathogenic mechanisms and therapeutic advances for allergic diseases. The present study aimed to summarize recent progress and explore future prospects of research performance by Korean allergists. We performed a comprehensive bibliometric analysis for research papers published in the Science Citation Index (SCI) or SCI-expanded journals by Korean allergists between 2009 and 2013. Research performance was quantitatively analyzed for the numbers of papers by publication year, research type, and main topic. In addition, the performance was also examined for qualitative indices, such as impact factor and citation number. A total of 1,091 papers were identified. The number of publication increased continuously, with an annual increase rate of 12.3%. Clinical and basic studies were the most frequent types of research, and recently the number of epidemiological studies has increased. By research topic, asthma was the most commonly studied, accounting for 20.9% of the total number of publications. Notably, the amount of rhinitis/rhinosinusitis research has risen steeply in 2013. Qualitative analyses also indicated continuous progress; the median impact factor of published journals increased from 1.918 in 2009 to 2.746 in 2013, yielding an annual increase rate of 7.4%. In conclusion, the present analyses identified a continuous increase in the research performance of Korean allergists over a recent 5 year period (2009-2013), both quantitatively and qualitatively. A more significant contribution is expected in the forthcoming era.     

Current Levels of Conflict of Interest Disclosure in Medical Publications from Korea

Medical research should be fully transparent. The aims of this study were to determine the prevalence of author-related conflict of interest (COI) policies and evaluate the actual state of COI disclosure in Korean medical journals. To determine the prevalence of author-related COI policies, we examined the 198 medical journals listed in the KoreaMed database. To investigate the actual state of COI disclosures in published papers, we analyzed the publications in a representative medical journal, the Journal of the Korean Medical Science, from the perspective of the relevance of the ethics of COI disclosure. A total of 164 (82.8%) journals required an author''s statement of COI as a criterion for publication. Of these 164, most of them focused on financial COI, with 101 (61.6%) presenting the information related to COI disclosures as a separate paragraph with a clear title. We identified 114 articles published by the Journal of the Korean Medical Science over a seven-year period, from January, 2006 to December, 2012. Of these, 65 papers (57%) included an author''s statement of COI. We found that the policies of Korean medical journals regarding the disclosure of author COIs are still behind the internationally suggested level.

Duplicate Publication Rate Decline in Korean Medical Journals

The purpose of this study was to examine trends in duplicate publication in Korean medical articles indexed in the KoreaMed database from 2004 to 2009, before and after a campaign against scientific misconduct launched by the Korean Association of Medical Journal Editors in 2006. The study covered period from 2007 to 2012; and 5% of the articles indexed in KoreaMed were retrieved by random sampling. Three authors reviewed full texts of the retrieved articles. The pattern of duplicate publication, such as copy, salami slicing (fragmentation), and aggregation (imalas), was also determined. Before the launching ethics campaign, the national duplication rate in medical journals was relatively high: 5.9% in 2004, 6.0% in 2005, and 7.2% in 2006. However, duplication rate steadily declined to 4.5% in 2007, 2.8% in 2008, and 1.2 % in 2009. Of all duplicated articles, 53.4% were classified as copies, 27.8% as salami slicing, and 18.8% as aggregation (imalas). The decline in duplicate publication rate took place as a result of nationwide campaigns and monitoring by KoreaMed and KoreaMed Synapse, starting from 2006.

Has there been an information explosion in histopathology?

The numbers of papers published between 1966 and 1990 which could be of relevance to a histopathologist were assessed. The search for papers was conducted under 18 medical subject headings using the CD-Plus Medline computerised database for the years 1966, 1978, 1982, 1986 and 1990. Between 1966 and 1990 16 categories showed an increase in the number of indexed papers and in 11 of these the increase was by over 200%. The two categories that showed a slight reduction were cytodiagnosis and polarisation microscopy. The total number of papers of probable relevance to histopathology in 1990 was 36,780, a 293% increase since 1966; this increase was greater than the increase in the total number of papers indexed (189%). The number of papers relevant to histopathology has increased dramatically in recent years and this increase has been proportionately greater than in some other areas of medicine.

Duplicate Publications in Korean medical journals indexed in KoreaMed

Duplicate publication is considered unethical. It has several negative impacts. To estimate the frequency and characteristics of duplicate publications in Korean medical journals, we reviewed some portion of Korean journal articles. Among 9,030 articles that are original articles indexed in KoreaMed from January to December 2004, 455 articles (5%) were chosen by random sampling. PubMed, Google scholar, KMbase, and KoreaMed were searched by two librarians. Three authors reviewed titles, abstracts, and full text of index articles and suspected articles independently. Point of disagreement were reconciled by discussion. Criteria for a duplicate publication defined by editors of cardiothoracic journals and International Committee of Medical Journal Editors were used. A total of 455 articles were evaluated, of which 27 (5.93%) index articles were identified with 29 duplicate articles. Among 27 index articles, 1 was quadruple publication and 26 were double publications. Of 29 duplicated articles, 19 were classified as copy, 4 as fragmentation, and 6 as disaggregation. The proportion of duplicate publications in Korean medical journals appears to be higher than expected. Education on publication ethics to researchers is needed.

Clinical Characteristics of Radiation Oncology in Korea during Past 10 Years

To understand trends in the clinical characteristics of radiation oncology over the last 10 yr in Korea, annual survey questionnaires were sent to all of Korean radiation oncology facilities since 1990. Questionnaires addressed basic radiation therapy facilities and the clinical information. Responses were obtained from all facilities, and data collected from 1997 to 2006 was analyzed. The numbers of new patients that have undergone radiation therapy and the numbers of hospitals with a department of radiation oncology have steadily increased over the past 10 yr, and totaled 37,215 patients and 60 hospitals, respectively, in 2006. However, the proportion of patients irradiated among total cancer patients has remained below 30% over the last 10 yr. The numbers of prostate cancer, breast cancer, and hepatoma have increased by more than 3 fold over the past 10 yr. Moreover, the percentage of irradiated patients treated by brachytherapy was 10.3% in 1997, but this gradually fell to only 4.2% in 2006. The information collected described the role played by radiation oncology in Korea. Continuous surveys are required to enable trends to be detected.
