Authors are expected to conform to the basic standards of professional ethics widely required in scholarly publishing such as on plagiarism and data manipulation. Careful and appropriate citations should be included of prior works related to their research. Proper co-authorship should have been discussed based on the individual contributions to the manuscript and JKAS will assume that the consent of the co-authorship has been made before submission of the manuscript. Original contributions should be distinct from the authors' own papers previously published or submitted to other journals. It is the authors' responsibility to obtain appropriate permissions, and to give proper credit in the manuscript when it contains copyrighted material.You can read the full KAS ethics policy written in Korean.
