  • Instructions for Authors

Enacted December 1, 2016

The Precision and Future Medicine (Precis Future Med, P&FM) is an official publication of the Sungkyunkwan University School of Medicine. Anyone who would like to submit a manuscript is advised to carefully read the aims and scope section of this journal. Manuscripts submitted to P&FM should be prepared according to the following instructions. For issues not addressed in these instructions, the author is referred to the International Committee of Medical Journal Editors (ICMJE) “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals” (



The aims of Precision and Future Medicine (P&FM) are to convey new messages regarding general medicine to the global community and to encourage and expedite the publication of medical discoveries, innovations, and new concepts in medicine for our beneficiaries. Thus, this journal, although it is aiming to become a general medical journal, is distinct from ordinary medical journals as it accepts and publishes new and innovative diagnostic and therapeutic information with greater priority over conventional clinical trial results. This journal will publish not only clinical papers but also translational, genomic, therapeutic, and biotechnological research papers. The journal also welcomes laboratory and animal studies on new drugs and novel medical devices and those that elucidate targetable mechanisms of human diseases. These aims and scope will be executed through various types of publications—Original Articles, Reviews, Research Methods, Analyses, Case Reports, Letters to the Editor, and Editorials. The number of case reports published will be limited for each issue. It is published four times per year: March 31, June 30, September 30, and December 31.


The journal adheres to the ethical guidelines for research and publication described in Guidelines on Good Publication ( and Good Publication Practice Guidelines for Medical Journals (

1. Authorship and Author’s Responsibility
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; and (4) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. Authors should meet these four conditions.
After the initial submission of a manuscript, any changes whatsoever in authorship (adding author(s), deleting author(s), or re-arranging the order of authors) must be explained by a letter to the editor from the authors concerned. This letter must be signed by all authors on the paper. Copyright assignment must be completed by every author.
The corresponding author takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process, and typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and gathering conflict of interest forms and statements, are properly completed, although these duties may be delegated to one or more coauthors. The corresponding author should be available throughout the submission and peer review process to respond to editorial queries in a timely manner, and should be available to respond to critiques of the work and cooperate with any requests from the journal for data or additional information or questions about the paper even after publication. P&FM does not allow multiple corresponding authors for one article. Only one author should correspond with the editorial office and readers for one article. P&FM does accept notice of equal contribution for the first author when the study was clearly performed by co-first authors. There is no limitation on the number of authors.
2. Originality, Plagiarism, and Duplicate Publication
Submitted manuscripts must not have been previously published or be under consideration for publication elsewhere. No part of the accepted manuscript should be duplicated in any other scientific journal without the permission of the Editorial Board. Submitted manuscripts are screened for possible plagiarism or duplicate publication by Crossref Similarity Check ( upon arrival. If plagiarism or duplicate publication related to the papers of this journal is detected, the manuscripts may be rejected, the authors will be announced in the journal, and their institutions will be informed. There will also be penalties for the authors.
A letter of permission is required for any and all material that has been published previously. It is the responsibility of the author to request permission from the publisher for any material that is being reproduced. This requirement applies to text, figures, and tables published by any of the authors themselves or used from another source, unless it is in the public domain.
3. Secondary Publication
It is possible to republish manuscripts if they satisfy the conditions of secondary publication of the ICMJE Recommendations (
4. Conflict of Interest Statement
The corresponding author must inform the editor of any potential conflicts of interest that could influence the authors’ interpretation of the data. Examples of potential conflicts of interest are financial support from or connections to pharmaceutical companies, political pressure from interest groups, and academically related issues. In particular, all sources of funding applicable to the study should be explicitly stated.
5. Registration of Clinical Trial Research
It is recommended that any research that deals with a clinical trial be registered with a primary national clinical trial registration site, such as, or other sites accredited by the World Health Organization as listed at
6. Statement of Informed Consent and IRB Approval
Copies of written informed consent and Institutional Review Board (IRB) approval for clinical research should be kept. If necessary, the editor or reviewers may request copies of these documents to resolve questions about IRB approval and study conduct. In addition, for studies conducted with human subjects, the method by which informed consent was obtained from the participants also needs to be stated in the Methods section.
7. Statement of Human and Animal Rights
All human and animal investigations must be conducted according to the principles expressed in the World Medical Association Declaration of Helsinki: Ethical Principles for Medical Research Involving Human Subjects (
8. Process for Managing Research and Publication Misconduct
When the journal faces suspected cases of research and publication misconduct such as redundant (duplicate) publication, plagiarism, fraudulent or fabricated data, changes in authorship, an undisclosed conflict of interest, ethical problems with a submitted manuscript, a reviewer who has appropriated an author’s idea or data, complaints against editors, and so on, the resolution process will follow the flowchart provided by the Committee on Publication Ethics ( The discussion and decision on the suspected cases are carried out by the editorial board.
9. Editorial Responsibilities
The editorial board will continuously work to monitor and safeguard publication ethics: guidelines for retracting articles; maintenance of the integrity of the academic record; preclusion of business needs from compromising intellectual and ethical standards; publishing corrections, clarifications, retractions, and apologies when needed; and excluding plagiarism and fraudulent data. The editors maintain the following responsibilities: responsibility and authority to reject and accept articles; avoiding any conflict of interest with respect to articles they reject or accept; promoting publication of corrections or retractions when errors are found; and preservation of the anonymity of reviewers.


1. Copyright

• Table: Tables are to be numbered in the order in which they are cited in the text. A table title should concisely describe the content of the table so that a reader can understand the table without referring to the text. Each table must be simple and typed on a separate page with its title. Explanatory matter is placed in footnotes below the table and not included in the heading. All non-standard abbreviations are explained in the footnotes. Footnotes should be indicated by a), b), c), d), ... Statistical measures such as SD or SE should be identified. Vertical rules and horizontal rules between entries should be omitted.
• Figure & legends for illustrations: Figures must be submitted as separate files saved in JPEG, TIFF, GIF, EPS, or PPT format (do not embedded the figures in the Microsoft Word manuscript file). Other formats of figure are negotiable. Contact editorial office for other formats. All images should exceed 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; or combination (line art and halftone) 600 dpi.
  Photographs of recognizable persons should be accompanied by a signed release from the person in the photograph or an appropriate legal guardian authorizing publication. Written permission should be obtained for the use of all previously published illustrations (and copies of permission letters should be included).
  Figures should be numbered, using Arabic numerals, in the order in which they are cited. In the case of multiple prints bearing the same number, use English letters after the numerals to indicate the correct order. (ex) Fig. 1A, Fig. 1B, C.
  If any tables or figures are moved or modified from other papers, authors should obtain permission through the Copyright Clearance Center or from the individual publisher if the materials are not included in open access journal published according to the Creative Commons license. If tables or figures are from open access journal, simply verify the source of the journal precisely in the footnote. Please note that a free access journal is different from that of open access; therefore, it is necessary to obtain permission from the publisher of the free access journal for using tables or figures from these sources.
• Supplementary data: If there are any supplementary materials to help the understanding of readers or too great amount data to be included in the main text, it may be placed as supplementary data. Supplementary data should be as concise as possible and must be related to the main conclusion of the paper. Supplementary data can include electronic files of high resolution images, background datasets, video materials, animations and more. Supplementary data will be published online alongside the electronic version of article. Video data files can be submitted in the same way as a figure or table by referring to the video or animation content. Since video and animation cannot be embedded in the print version, authors have to provide text for both the electronic and the print version for the portions of the article that refer to this content.
4. Reviews
Reviews are comprehensive analyses of specific topics. They are usually solicited by the Editor, but we will consider unsolicited material. Please send us a Presubmission Inquiry before writing a review article. All review articles undergo the same review process as other types of article prior to acceptance. They are organized as follows: title page, abstract and keywords, introduction, main text, conclusion, acknowledgments, references, tables, figure legends, and figures. Reviews have no restrictions on word count or the number of figures and tables. However, authors should eliminate redundancy, emphasize the central message, and provide only the data necessary to convey that message. The approximate length should be 3,000 to 5,000 words. There should be an unstructured abstract equal to or less than 200 words. References should not exceed 200.
5. Research Methods
Research methods report original work on methodological issues. These present methodological approaches, modifications of existing methods, or discussions of quantitative and data analytic approaches. General rules for original articles apply to this type.
6. Analyses
Analyses do not report original data, but are review-based reports including a new analysis of existing data (typically large biological data sets such as genomes, microarrays and proteomics) that lead to a novel, exciting and arresting conclusion. These are limited to 3,000 words, not counting the abstract, references, tables, and legends to figures and illustrations, if possible, and references should not exceed 30. A maximum of 5 figures including tables is allowed.
7. Case Reports
Case reports will be published only in exceptional circumstances, when they illustrate a rare occurrence of clinical importance. These manuscripts should be organized in the following sequence: title page, abstract and keywords, introduction, case report(s), discussion, acknowledgments, references, tables, figure legends, and figures. Case reports are limited to 1,500 words, not counting the abstract, references, tables, and legends to figures and illustrations, if possible, and references should not exceed 10. A maximum of 5 figures including tables is allowed.
8. Letters to the Editor
Letters to the editor may be in response to a published article, or a short, free-standing piece expressing an opinion.

In addition, if deemed necessary, a review of statistics may be requested. Authors' names and affiliations are removed during peer review. The acceptance criteria for all papers are based on the quality and originality of the research and its clinical and scientific significance. Acceptance of the manuscript is decided based on the critiques and recommended decision of the referees. An initial decision will normally be made within 2 weeks of receipt of a manuscript, and reviewers’ comments are sent to the corresponding authors by e-mail. Revised manuscripts must be submitted online by the corresponding author. The corresponding author must indicate the alterations that have been made in response to the referees’ comments item by item. Failure to resubmit the revised manuscript within 4 weeks of the editorial decision is regarded as a withdrawal. A final decision on acceptance for publication or rejection for publication is forwarded to the corresponding author from the Editorial Office.
• Appeals of decisions: Any appeal against the editorial decision must be made within 2 weeks of the date of the decision letter.

1. Final Version
After the paper has been accepted for publication, the author(s) should submit the final version of the manuscript. The names and affiliations of the authors should be double-checked and if the originally submitted image files were of poor resolution, higher resolution image files should be submitted at this time. The EPS, JPG, PPT, TIF formats are preferred for submission of digital files of photographic images. Symbols (e.g., circles, triangles, squares), letters (e.g., words, abbreviations), and numbers should be large enough to be legible on reduction to the journal’s column widths. All symbols must be defined in the figure caption. If references, tables, or figures are moved, added, or deleted during the revision process, renumber them to reflect such changes so that all tables, references and figures are cited in numeric order.
2. Manuscript Corrections
Before publication, the manuscript editor will correct the manuscript such that it meets the standard publication format. The author(s) must respond within 2 days when the manuscript editor contacts the author for revisions. If the response is delayed, the manuscript’s publication may be postponed to the next issue.
3. Gallery Proof
The author(s) will receive the final version of the manuscript as a PDF file. Upon receipt, within 2 days, the editorial office (or printing office) must be notified of any errors found in the file. Any errors found after this time are the responsibility of the author(s) and will have to be corrected as an erratum.
4. Errata, Corrigenda
For correcting errors in published articles, the corresponding author should contact the Journal's Editorial Office with a detailed description of the correction. Corrections that affect profoundly the interpretation or conclusions of the article will be reviewed by the Editors. Corrections will be published as Corrigenda (corrections of author's errors) or Errata (corrections of publisher's errors) in a later issue of the Journal.


There are no author submission fees or other publication-related charges. All cost for the publication process is supported by the Publisher. P&FM is a so-called platinum open access journal which does not charge author fees.
