KJCCM is published quarterly at the end of February, May, August, and November. Manuscripts for submission to KSCCM should be written according to the following instructions for authors. Editorial Board will make the final decision on an approval for the publication of submitted manuscripts and the publication order of accepted manuscripts. Editorial Board reviews ethics, rationality, originality, and scientific significance in accepting submitted manuscripts, and can request any further corrections, revisions, and deletions of the article if necessary. The Korean Journal of Critical Care Medicine follows the Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication, available at: http://www.icmje.org/, if otherwise not described below.


1. Publication Types

The KJCCM focuses on original articles, case reports, reviews, letters to the editor, editorials, and images in critical care.

2. Research Ethics

Clinical research should be done in accordance of the Ethical Principles for Medical Research Involving Human Subjects, outlined in the Helsinki Declaration (http://www.wma.net). All studies (including case reports) of human subjects must contain an appropriate statement within the Materials and Methods or case presentation section indicating approval of the study by the Institutional Review Board (IRB) that subjects have signed written informed consent or that the IRB waived the need for informed consent. Human subjects should not be identifiable, such that patients’ names, initials, hospital numbers, dates of birth, or other protected healthcare information should not be disclosed.
All studies in which animals are used must contain a statement within the Materials and Methods section confirming approval by the Institutional Animal Care and Use Committee (IACUC) and that the care and handling of the animals were in accord with National Institutes of Health (NIH) Guidelines or another appropriate internationally recognized guideline for ethical animal treatment.
The journal adheres to the ethical guidelines for research and publication described in the Council of Science Editors, International Committee of Medical Journal Editors, and World Association of Medical Editors.
Authors who has a financial involvement with any organization or entity with a financial interest in or in financial competition with the subject matter or materials discussed in the manuscript should disclose that affiliation. The manuscript should clearly identify the financial support of the research.

3. Copyright and Publication Ethics

Copyrights ownership is to be transferred to the KSCCM. The authors should submit “Authorship Responsibility and License Agreement Form” at the time of manuscript submission.
All submitted manuscripts should be original and should not be considered by other scientific journals for publication at the same time. Any part of the accepted manuscript should not be duplicated in any other scientific journal without the permission of the Editorial Board. If duplicate publication related to the papers of this journal is detected, the authors will be announced in the journal and their institutes will be informed, and there also will be penalties for the authors.
It is possible to republish manuscripts if the manuscripts satisfy the regulation of secondary publication of the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, available at: http://www.icmje.org/.
