1. Research and publication ethics
If there is any conflict of interest, the authors should disclose it. If medicine or medical equipment is involved, the authors should clarify any commercial relationship with the manufacturer or research funds from the manufacturer.
For human research, the study should follow the Declaration of Helsinki, available at http://www.wma.net. For animal studies, the authors should indicate how they minimized pain or discomfort to the animals in keeping with The Institutional Guide for the Care and Use of Laboratory Animals.
Approval from the Institutional Review Board (IRB) is required for clinical research. Clinical trials should be registered with a primary national clinical trial registration site, such as the Korea Clinical Research Information Service (CRiS), available at http://cris.cdc.go.kr or other sites accredited by the World Health Organization (WHO) or the International Committee of Medical Journal Editors and the registration number should be cited in the Abstract.
Authorship credit should be based on 1) substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data, 2) drafting the article or revising it critically for important intellectual content, and 3) final approval of the version to be published according to The Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication. Any papers that are forged, altered, plagiarized, redundant, or dishonest cannot be published. The submitted manuscript will be checked for plagiarism using CrossCheck (http://crossref.org/crosscheck.html). Secondary publication is allowed only if its language is different, the readers are different, and the two journal editors agree.
Regarding policies on research and publication ethics that are not stated in these instructions, The Good Publication Practice Guidelines for Medical Journals, available at http://kamje.or.kr/publishing_ethics.html, or the guidelines on Good Publication, available at http://www.publicationethics.org.uk/, can be applied.
2. Publication types
Original articles: These describe new findings from clinical studies or basic research that may contribute to clinical diagnosis and treatment or an understanding of pathogenesis or epidemiology.
Case reports: A report on a single case or an analysis of a few cases to add to the clinical spectrum. The case should be significant clinically, new, and rare.
Review articles: A concise compilation of the knowledge and skill in a specific area to provides hints for patient management or outline recent research activity. A review article is usually invited by the editorial board.
Brief reports: Reserved for the rapid and concise circulation of simple, but meaningful data, preliminarily remarkable findings before a full description, or a follow-up study.
Letters to the editor: Any comments or opinions on published papers or suggestions for the journal are welcomed.
3. Peer review
Every submitted manuscript is peer-reviewed by at least three reviewers before deciding whether to accept or reject it, or return it for revision. The review system is single blinded so that authors cannot identify reviewers. The review process is carried out through a manuscript management system. If the authors are asked to revise the manuscript, they should revise it based on the reviewers’ comments or provides a reasonable answer to the reviewers’ comments justifying why they did not revise it. The authors should reply and upload the revised manuscript within 8 weeks after receiving the review results. Otherwise, they are considered to have withdrawn the manuscript. However, the authors can extend the due time in case of requiring more times for revision after notification.

7. Correction policy
We recognize our responsibility to correct errors that we have
previously published. We expect authors to inform the journal
of any errors they have noticed in their article once published.
Corrections are made according to the journal’s discretion.
Erratum concerns notification of an important error made by
the journal that affects the publication record or the scientific
integrity of the paper, or the reputation of the journal or authors.
Errata must be requested by authors within the journal
policy. Errata are not generally published for simple, obvious
typographical errors. However, errata are published when an
apparently simple error is significant (for example a Greek alpha
for an 'a' in a unit, or a typographical error in the corresponding
8. Manuscript preparation
The manuscript should be prepared with Microsoft Word or in RTF format. It should be double-spaced in font size 10 on A4 sized paper. Number the pages consecutively, beginning from the title page.
A cover letter should inform the editor that neither the submitted material nor portions of it have been published previously or are under consideration for publication elsewhere. When more than one related manuscript has been published or is under consideration for publication by this or other journals, the authors must declare this in their letter and enclose copies of those publications for editorial perusal. Failure to do so may lead to automatic rejection of the submitted manuscript. The corresponding author should certify that all listed authors participated meaningfully in the study and that they have seen and approved the final manuscript.
