• Copyright Transfer

  The copyright of published manuscripts is held by the Korean Sleep Research Society. Published data, tables, or figures cannot be reproduced elsewhere for commercial purposes without permission from the copyright holder. All authors must agree and sign the “author consent form” regarding copyright transfer agreement, conflict of interest, and ethical statement, which can be downloaded from the JSM online submission page (https://www.e-jsm.org/).

Manuscript Preparation

JSM publishes manuscripts pertaining to a wide spectrum of clinical and translational investigations in sleep research. Authors should follow the recommendations for the conduct, reporting, editing, and publication of scholarly work in medical journals (available from http://www.icmje.org/about-icmje/faqs/icmje-recommendations/). The manuscript can be written in Korean or English.

• General Style

  JSM publishes Original Article, Reviews, Case Report, Pictorial Essay, and Letter to the Editor.

  1.1. Original Article

  Original Articles present original research findings in the fields of sleep medicine and science. Original Articles should include:

  • (i) Title page: Title, authors’ affiliation, and corresponding author’s affiliation should be included.

  2.5. Main Body

  (i) Introduction
  State the purpose of the study with relevant background description.
  
  (ii) Methods

  (iv) Discussion
  Concisely interpret the results and relate them to previous work in the field. The results related to the purpose of the reported study should be clearly described. Do not rewrite the results but emphasize significant and important research results. Discuss the significance and limitations of this study.
  
  (v) Acknowledgment
  List people who have made substantial contributions to the research and/or manuscript (e.g., study conduct, data collection, data analyses, and writing or editing assistance), but who do not fulfill authorship criteria. All persons listed in the Acknowledgments should provide the corresponding author with permission to be named in the manuscript. If there is nothing to disclose, declare “None.” Authors should enter the sources of funding for a study when submitting an article in the submission system.

  (viii) Author Contributions
  The contributions of all authors must be described. List the initials of the authors who made at least one key contribution. Examples of authors’ contributions are as follows: conceptualization, data curation, formal analysis, funding acquisition, investigation, methodology, project administration, resources, software, supervision, validation, visualization, writing—original draft, and writing—review and editing.
  
  (ix) References
  References should conform with the guidelines specified in the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals-Vancouver style.”
  

  • References should be written in English.
  • References should be numbered serially in the text using superscript unparenthesized Arabic numerals.
  • When three or more references are cited at one place in the manuscript, a hyphen should be used to join the first and last numbers of a series; commas should be used without spaces to separate other parts of a multiple-reference citation (e.g., ^3-5 or ^3-5,7).
  • Provide all authors’ names when fewer than six; when six or more, list the first three followed by “et al.”
  • For journal names, use abbreviations as listed in the Index Medicus in italics.
  • Personal communications, unpublished observations, and submitted manuscripts are not legitimate references for publication. They must be cited in the text only as follows: Kim SB (personal opinion) or Kim SB (unpublished observation).
  • “In press” citations must have been accepted for publication and the name of the journal or book publisher must be included.

  2.8. Manuscript Format

  Translation of medical terms in Korean manuscripts follows recommendations from the Korean Medical Association. If no proper medical terminology can be found, nouns, drug names, units, etc., can be used in the original language. If the translated term needs the original language for further clarification, the original language should be written in parentheses when the term first appears; subsequently, only the translated term should be used. Please limit the use of abbreviations. When abbreviations are used, they should be spelled out in parentheses when first used in the article. Numbers should be given as Arabic numerals, and units should follow the International System of Unit (SI).

Review Process

The Editor-in-Chief and Associate Editors first review the submitted manuscript to determine if it is suitable for review and publication. The editorial board can immediately reject in cases of 1) unrelated topics to the aims and scopes of JSM, 2) manuscripts that do not follow the author’s instructions, or 3) insufficient quality, novelty, or importance to warrant publication. The selected manuscripts are then reviewed by two peer reviewers. A third reviewer may be selected if there are conflicting recommendations. Reviews are blinded to the authors’ information.

Proofreading

After acceptance of all manuscripts, page proofs will be sent to the corresponding author for review and approval. The authors are responsible for conciseness, clarity, grammar, and spelling, but major editing is not allowed. The editorial board can make minor revisions before publication.

Submission

To submit a manuscript, please visit:https://submit.e-jsm.org Manuscripts are published in JSM at no cost to the authors.
