概要	Duplicate publication occurs when the same research data are published more than once without acknowledgment or justification, presenting the same or substantially similar results as previously published work. Salami slicing is the related practice of dividing the results of a single study into the smallest possible publishable units and submitting them as separate papers to multiply publication counts. Both practices artificially inflate research output, mislead readers, and violate ethical standards upheld by the Committee on Publication Ethics (COPE) and research integrity organizations worldwide.	The Committee on Publication Ethics (COPE), founded in 1997, is an international organization of journal editors and publishers that promotes and advances research integrity and publication ethics. COPE provides practical guidance through flowcharts, position statements, and ethical guidelines addressing misconduct (fabrication, falsification, plagiarism), authorship disputes, conflicts of interest, and corrections. COPE's resources are freely available and adopted by thousands of journals globally. COPE is not a regulator; it advises editors and researchers on handling ethical issues and promotes a culture of integrity in publishing.
