Ahn, Lee, Kwak, Kim, and Choi: The trends of duplicate publication in Korean Medical journals

Abstract

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.

Table 1
Criteria of Duplicate Publication and Acceptable Secondary Publication
Criteria of duplicate publication Criteria of acceptable secondary publication
The hypothesis is similar The authors have received approval from the editors of both journals
The numbers or sample sizes are similar The priority of the primary publication is respected by a publication interval of at least one week
The methodology is identical or nearly so The paper for secondary publication is intended for a different group of readers
The results are similar The secondary version faithfully reflects the data and interpretations of the primary version
At least one author is common to both reports There is a footnote and title on the title page of the secondary version
No or little new information is made available
