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conflict, voluntary withdrawal of a paper, or non-compliance with publishing regulations, the manuscript must be withdrawn according to specific procedures (referring to the COPE flow chart).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.

韩国科学编辑委员会出版伦理委员会处理的 2016 年至 2020 年出版伦理咨询问题

为了改善出版生态系统和提高期刊出版的透明度，我们描述了韩国科学出版的一些最新案例。目前的文章总结了国内期刊和出版商的伦理调查，其中大多数是韩国科学编辑委员会的成员。我们选择了过去 4 年提出的 15 个具有代表性的问题。这些查询被分类为热点话题，如剽窃、重复出版物、多次提交和其他（知情同意、版权、遵守期刊规定、作者责任和自愿撤稿请求）。当怀疑抄袭时，编辑和审稿人应按照相关规则和程序评估情况，必要时拒稿。重复发表的情况应在双方期刊主编明确同意的基础上，在两篇论文中明确说明。一般来说，一篇文章的全部内容应该在一期发表，但如果文章太长，可能需要在两期发表。需要两个期刊的许可。摘要和参考文献应相应分开。如发生版权冲突、论文自愿撤稿或不符合出版规定，必须按具体程序撤稿（参见COPE流程图）。所有与稿件相关的通信都应与直接与期刊沟通的通讯作者联系。
