Objectives: The purpose of this study was to examine trends in duplicate publication in Korean medical articles indexed in the Oriental Medicine Advanced Searching Integrated System(OASIS). Methods: We searched the list of papers published in Korean medical journals by using OASIS. We randomly extracted 10% of total articles (n=1,162). We searched using OASIS by entering keywords from the title and names of the first and last authors of each indexed article. After the librarian selected the candidates of duplicate publication, three authors reviewed the full texts of the articles independently. When their opinions were not in agreement, reconciliation was made by discussion. The patterns of duplicate publication, such as copy, salami slicing (fragmentation), and aggregation (imalas), were also determined. Results: A total of 1162 articles were evaluated, 24 (2.1%) index articles of which were duplicate articles. Among 24 index articles, Two were triple publications and 22 were double publications. The patterns of duplication publication were as follows; (1) copy (n=8, 33.3%); (2) salami (9, 37.5%), (3) imalas (5, 20.8%) (4) others (2, 8.3%). Conclusion: Duplicate publications have appeared in Korean medical journals in a small proportion. Education on publication ethics and authors'ethical awareness is needed.
