Instructions for Authors    Copyright Transfer Form

Types of Manuscript

The Journal of Sleep Medicine publishes Original Article, Reviews, Editorials, Case Reports, and images in sleep medicine. Acceptance of Case Reports and Letters to the Editor is very limited, and only reports that make a major clinico-pathological or educational contribution or suggest a significant change of diagnosis or therapy will be accepted.

Ethical Policy

A submitted manuscript must not be associated with any type of research misconduct, including fabrication, falsification, and plagiarism with intent to deceive by the authors. The cover letter to the Editor-in-Chief must declare that a submitted manuscript has not been published nor is under simultaneous consideration for publication elsewhere in whole or in part in any language except in the form of an abstract. The cover letter must also state if the manuscript contains any portion that may be regarded as redundant or duplicate information, defined as a paper, data, tables, or figures that overlap substantially with already published information. The author should include within the manuscript indicating that the submitted study was approved by the relevant research ethics committee or Institutional Review Board (IRB). Research involving human subjects must comply with the principles of the Declaration of Helsinki (1964). Articles describing research involving animals must state in the Methods section that the work was approved by the applicable institutional ethics committee or review board. The manuscript must also state that informed consent was obtained from the subjects, when appropriate. The Editor-in-Chief has the right to reject a manuscript if research misconduct is suspected. For the policies on the research and publication ethics not stated in these instructions, ‘Good Publication Practice Guidelines for Medical Journals (http://kamje.or.kr/publishing_ethics.html)’ or ‘Guidelines on good publication (http://www.publicationethics.org.uk/guidelines)’ can be applied.

Copyright Transfer Agreement

The copyright of published manuscripts is held by the Korean Sleep Research Society. The Author Disclosure Form states that the use of data, tables, figures, or videos (except for lectures) published in the Journal of Sleep Medicine without written permission of the copyright holder is plagiarism, even if the authors use them from their own papers.

Online Submission Information

The Journal of Sleep Medicine offers authors Web-based manuscript submission and peer review at http://ems.sleepnet.or.kr/. Please review the instructions at the website carefully and take note of the further instructions provided at the top of each screen of the five stage submission process. Submit your manuscript and all figures exactly as instructed to avoid failure or delay in processing.

Users must register when accessing the Journal of Sleep Medicine online submission system for the first time, by clicking on “Register”. You will be asked to complete according to the instruction in order to obtain your personal account.


We strongly recommend you to create ID, which is easy-to-remember. The password will be encrypted for security reasons, and will not be known to Journal of Sleep Medicine. A verification email will be emailed to you at the address you used to register.


Once you have verified your email address, you will be asked to provide a basic profile consisting of your contact information.

Uploading a Manuscript

Once logged in to the Korean Sleep Research Society online submission system, click on the “Submit a new manuscript”. You will be presented with a series of fields for entering information about your manuscript and uploading the manuscript, image, and supplemental files.

You may begin a submission or continue the process at a later date by clicking on “Save/Next” at the bottom of the screen when entering your manuscript information. This enables you to save that page or continue to the next page. If you choose not to complete the submission during a particular session, your manuscript will appear in the “incomplete submission” queue in “My Manuscript”. Do not submit the same paper more than once.

After completing the submission, the manuscript number will be sent to the email address specified, and this should be quoted in all subsequent communications. This email notification will be sent after we have confirmed that the submitted manuscript is consistent with the journal style. Manuscripts that do not conform to the style of the Journal of Sleep Medicine might be returned without further review, requiring you to correct the style of the manuscript before resubmitting it.

Please note

For a blind review, do not include author information on the title page. Instead, provide the author information page as a separate file when uploading the manuscript. Prepare the title page as the first page of the main document file. The abstract should appear on page 2 of the main document file.

Supplemental Data

Supplemental Data is content that the authors wish to make available online if the paper is accepted for publication.

Manuscript Status

Submitting a Revision

To submit a revised manuscript via the Journal of Sleep Medicine online submission system, click on “Submit a revised manuscript”. You will be presented with information on the original version of your manuscript, which should be edited as necessary. You will then be required to upload the files related to the revised version. Do not submit revisions with the edits displayed (e.g., the Track Changes tool in Microsoft Word should be turned off when making edits). Please include your responses to the reviewer comments to the Editor-in-Chief.

Manuscript Preparation

General Style

The manuscript must contain the author information page, title page, abstract, main text, references, tables, and figure legends. Leave margins of 3.0 cm on each side. The main body of the manuscript and all tables included with your submission must be provided in Microsoft Word format. The text must be written in double-spaced 10-point font, preferably in Times New Roman. The right margin should not be justified (i.e., left-justification only). Abbreviations should only be used for terms that are used at least twice, and should be defined separately on first use in the Abstract and main text. Place the page number in the middle of the bottom of each page from the title page onwards. Do not submit the manuscript with automatic formatting features (e.g., when using End- Note, remove field codes before submission).

Title Page

This page should contain the title, running title, number of characters of the title, number of words in the manuscript (excluding references, tables, and figure legends), number of figures, and number of tables. Total number of figures and tables should not exceed seven in an original paper and three in a case report. The author names should not appear on this page. This is considered the first page of the manuscript.


The Abstract must appear on a separate page. All original articles, case reports, and reviews must include structured abstracts that do not exceed 250 words for original articles and reviews, 150 words for case reports. For original articles, abstract should be organized into Objectives, Methods, Results, and Conclusions with these titles terminated with a colon and in boldface. Abstracts are required for Reviews, but a structured format as in Original Articles is not necessary. For Case Reports, the abstract must be organized into Background, Case report, and Conclusions, and should not exceed 150 words. Total of 6 or less keywords for original article and reviews, and 3 or less for case report, should be provided at the end of this page. Important terms can be selected from the Medical Subject Heading (MeSH) of Index Medicus.

Main Text

The main body of the manuscript must be prepared under the following subheadings: Introduction, Methods, Results, and Discussion. For each paragraph, (1) do not indent the first line, (2) ensure that it is separated from the previous paragraph by a vertical space, and (3) do not include any new-line or new-paragraph marks (except at the end). Do not include any new-page marks in the file. Case Reports must use subheading of “Case report” for description of case and its related results instead of Methods and Results. Letters to the Editor should not exceed 500 words, and 250 words for images in sleep medicine including title page, image legends and references. One figure or table is allowed.


All sources of funding and financial or material support should be clearly stated in the Author Disclosure Form and in the acknowledgement. All authors are also required to report potential conflicts of interest (http://journal.sleepnet.or.kr/authors/publish.php), including funding and specific financial interests relevant to the subject of their manuscript in an acknowledgement.


References should be numbered serially in the text using numbers as unparenthesized superscripts: 3,7,10-12. They should be listed on a separate sheet at the end of the paper in that order. Unpublished data and personal communications may be cited in the text (including the initials and surnames of all authors, and the year in which the observation was made), but should not be listed as references. Authors are responsible for the accuracy of references. Reference format should conform with that specified in “Uniform Requirements for Manuscripts Submitted to Biomedical Journals-Vancouver style”. Journal abbreviations should conform with the style used in the Cumulated Index Medicus. Do not reference papers that are “submitted”; these can be specified as unpublished data in the body of the text. Personal communications should also be mentioned in the body of the text only. List all authors when they are six or fewer; when there are seven or more, list only the first three and add “et al.”. The endnote reference style for the Journal of Sleep Medicine is specified on the journal homepage.

Type each table, with a title, on a separate sheet. Each table should be included as a Word table in order to ensure correct column alignment. Cite and number tables in the order they are mentioned in the text. Use horizontal lines only above and below column headings and at the bottom of a table. Do not use vertical lines. All abbreviations should be spelled out when they first appear in tables. For footnotes, use the following symbols in the indicated sequence: *, †, ‡, §, ∥, ¶, **, †† and ‡‡. The significance of observations, as determined by appropriate statistical analyses, must be indicated.

Figures must be submitted as separate files saved in JPEG, TIFF, or PPT format (do not embedded the figures in the Microsoft Word manuscript file). All images should be above the following image resolutions; Line Art (an image composed of lines and text) 1,000 dpi, Halftone (a continuous tone photograph, which contains no text) 300 dpi, Combination (Line Art + Halftone) 600 dpi. Photographs of recognizable persons should be accompanied by a signed release from the patient or legal guardian authorizing publication. Legends for figures must appear on a separate page at the end of the manuscript file.

Accepted Articles: Materials Required for Publication

After Acceptance

The corresponding author should send a signed copyright transfer and author consent form in advance to the Editorial Office by email or fax, since manuscripts cannot be published unless these items are received by the Editorial Office. You can download copyright transfer and author consent forms from (http://ems.sleepnet.or.kr/) the Journal of Sleep Medicine online submission page. The copyright transfer includes images of patients, whether in artwork or video format. The corresponding author should state in the Methods section that informed consent was obtained from the subjects. These do not have to be sent to the Editorial Office, but they should be kept in case they are requested.

Proofs and Reprints

Proofs must be returned after receipt; late return might delay the publication of a paper. Please check text, tables, legends, and references very carefully. To expedite publication, page proofs rather than galleys will be sent electronically to the corresponding author. Substantial alterations by the authors other than the correction of printing errors might incur additional charges. The order form for reprints included with the proofs should be returned even if you are not ordering reprints.
