Consultation questions on publication ethics from 2016 to 2020 addressed by the Committee on Publication Ethics of the Korean Council of Science Editors

With the goal of improving the publishing ecosystem and promoting transparency in journal publishing, we describe some recent cases in scientific publishing in Korea. The current article summarizes ethical inquiries from domestic journals and publishers, most of whom are members of the Korean Council of Science Editors. We selected 15 representative questions asked during the last 4 years. Those inquiries were classified into hot topics such as plagiarism, duplicate publications, multiple submission, and others (informed consent, copyright, compliance with journal regulations, authors’ responsibilities, and voluntary retraction requests). When plagiarism is suspected, editors and reviewers should assess the situation following the relevant rules and procedures, and if necessary, the manuscript should be rejected. Cases of duplicate publication should be clearly stated in both papers based on the explicit agreement of the editor-in-chief of both journals. As a general rule, the entire content of an article should be published in one issue, but if the article is too long, it may need to be published in two issues. Permission from both journals is required. The abstract and references should be separated accordingly. In cases of copyright conflict, voluntary withdrawal of a paper, or non-compliance with publishing regulations, the manuscript must be withdrawn according to specific procedures (referring to the COPE flow chart). All correspondence regarding a manuscript should be with the corresponding author, who communicates directly with the journal. We hope that these recommendations will help readers in the field of scientific publishing to address issues related to publication ethics.
