The goal of the Yonsei Medical Journal (YMJ) is to publish high quality manuscripts dedicated to clinical or basic research. Any authors affiliated with an accredited biomedical institution may submit manuscripts of original articles, review articles, case reports, brief communications, and letters to the Editor. Manuscripts are received with the understanding that they are not under simultaneous consideration by any other publications, and that the authors realize that the identities of the reviewers are kept confidential. The Editors reserve the right to make corrections, both literary and technical, to the papers. It is the author's responsibility to ensure that a patient's anonymity be carefully protected and to verify that any experimental investigation with human subjects reported in the manuscript was performed with informed consent and follows all guidelines for experimental investigation with human subjects required by the institution(s) with which all the authors are affiliated. YMJ is published bimonthly and issuing dates are the first days of January, March, May, July, September, and November. The copyright of published manuscripts is held by the YMJ. The agreement of copyright transfer from all the authors should be sent with the original manuscript submission. A copyright transfer form is available at the journal homepage.

Any potential conflicts of interest must be disclosed in this section. If there are no potential financial conflicts of interest, the following statement should be added: "The authors have no financial conflicts of interest."

Research on humans or animals must be approved by the IRB. Please refer to the principles embodied in the Declaration of Helsinki (http://www.wma.net/e/policy/b3.htm).

All new manuscripts should be submitted directly to: In-Hong Choi, M.D., Ph.D., Editor-in-Chief, using the online submission system: http://journal.eymj.org Acceptance of manuscripts is based on many factors, including the importance, originality, and priority of the research. The Editor-in-Chief and an Associate Editor generally review manuscripts. Then the selected manuscripts are reviewed by at least two external peer reviewers, and when required, a biostatistician. Upon completion of the review, authors will receive notification of the Editor's decision by e-mail with comments offered by the reviewers. The author(s) can recommend up to 5 candidates to review the manuscript.
