Preventive Nutrition and Food Science (Prev. Nutr. Food Sci.; PNF) is an international open access journal published quarterly (last day of March, June, September, and December) by The Korean Society of Food Science and Nutrition (KFN). It publishes original articles, reviews, research notes, and letters to the editor on the chemical, biological, health, and disease preventive aspects of food components. In particular, the Journal encourages papers dealing with the preventive effects of nutrients and food components on chronic disease development and modification of their bioactivity by food processing. The PNF is primarily or scientists and clinicians active or interested in the field of Preventive Nutrition and Food Science. Its readership can be expanded to researchers, professors, students, technicians, and policy makers. The PNF is currently indexed in PubMed and PubMed Central, also covered in Scopus, Chemical Abstract, and Korea Citation Index, etc. All the articles can be accessed on the Journal website (https://www.pnfs.or.kr).

Authorship

Authorship provides credit for a researcher’s contributions to a study and carries accountability. Authors are expected to fulfil the criteria below:


  • Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
  • Drafting the work or revising it critically for important intellectual content; AND
  • Final approval of the version to be published; AND
  • 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

Those who do not meet all four criteria should be acknowledged. The purpose of these authorship criteria is to reserve authorship status for those who deserve credit and take responsibility for the work.

Animal or Human Studies

If either animal studies or human studies are to be described in manuscript, following information should be addressed by the authors: In case of animal studies, the permission/approval of institutional or national authorities on the care and use of animals and specific approval/ethics number must be stated by the authors. In addition, all the experimental procedure using animals should be approved by authorizing body. In human studies, the principles outlined in the Declaration of Helsinki (https://www.wma.net/what-we-do/medical-ethics/declaration-of-helsinki/) should be followed and the approval of institutional ethical committee (with approval number) should be stated with the specific name of the approving authorities. All the participating subjects should provide the informed consent form and this should be stated in the manuscript. Subject anonymity must be preserved and confidential information should not be published. If identifying information is essential for scientific purposes, authors must provide a signed statement from the subject granting approval for the publication of identifying materials, including photographs. Any inhumane procedures in submitted papers will definitely result in disapproval of the paper with no exceptions.

Author Disclosure Statement

A statement describing any financial conflicts of interest or lack thereof is published with each manuscript. During the submission process, the corresponding author must provide this statement on behalf of all authors of the manuscript. This includes any financial (e.g., employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications, travel grants) or other relationships (e.g., academic or even personal) with commercial entities whose products or services are related to the subject matter in the manuscript, or to sociopolitical issues that could cause conflict. The statement will be published in the final paper. If no conflict of interest is declared, the following statement will be published in the paper: “The author(s) declare(s) no conflict of interest.”

Originality and Publication Ethics

All manuscripts should be original in nature and must not have been previously published or be under consideration for publication in other scientific journals at the time of submission. All manuscripts should follow the publication ethics at all times. These include issues concerning plagiarism, data fabrication or falsification, citation manipulation, improper authorship contribution, duplicate submissions, and redundant submissions. All submitted manuscripts are inspected by Similarity Check powered by iThenticate (https://www.crossref.org/services/similarity-check/), a plagiarism detection tool. If a significantly high degree of similarity score is found, then the editorial board will perform a more in-depth content screening. Any violation of publication ethics may lead to automatic rejection (at the time of submission) or withdrawal (for previously published articles).

Data Sharing Policy

This journal follows the data sharing policy stipulated in the “Data Sharing Statements for Clinical Trials: A Requirement of the International Committee of Medical Journal Editors” (https://doi.org/10.3346/jkms.2017.32.7.1051). As of July 1, 2018, manuscripts submitted to ICMJE journals that report the results of interventional clinical trials must contain a data sharing statement, as described below. Clinical trials that begin enrolling participants on or after January 1, 2019, must include a data sharing plan upon registration. Any changes to the data sharing plan after registration must be reflected in the statement submitted and published with the manuscript, and updated in the registry record. All authors of research articles that deal with interventional clinical trials must submit a data sharing plan. Depending on the extent of their data sharing plan, authors should deposit their data after deidentification and report the DOI of the data and the registered site.

Copyright

All manuscripts accepted for publication become the sole property of the Korean Society of Food Science and Nutrition. The corresponding author is required to download and sign the TRANSFER OF COPYRIGHT on behalf of all authors. It includes a statement for the full transfer of copyright to the Korean Society of Food Science and Nutrition (KFN), and must be submitted along with the manuscript. As an open-access journal, articles are distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided that the original work is properly cited. Permission requests to the KFN need not be made for the use of its tables or figures in other periodicals, books, or media for scholarly or educational purposes. Permission MUST be obtained from KFN (E-mail: office@pnfs.or.kr) prior to any commercial use of material from the open access version of the journal.

Secondary Publication

Manuscripts can be republished if they satisfy the following conditions of secondary publication stipulated in the “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals” by the International Committee of Medical Journal Editors (ICMJE) (http://www.icmje.org/): (1) The authors have received approval from the editors of both journals (the editor concerned with the secondary publication must have access to the primary version). (2) The priority of the primary publication is respected by a publication interval negotiated by the editors of both journals and authors. (3) The manuscript for secondary publication is intended for a different group of readers; an abbreviated version could be sufficient. (4) The secondary version faithfully reflects the data and interpretations of the primary version. (5) The secondary version informs readers, peers, and documenting agencies that the manuscript has been published elsewhere in whole or in part—for example, with a note that might read, “This article is based on a study first reported in the journal title, with full reference, and the secondary version cites the primary reference.” (6) The title of the secondary publication should indicate that it is a secondary publication (complete or abridged republication or translation) of a primary publication. Of note, the United States National Library of Medicine (NLM) does not consider translations as “republications” and does not cite or index them when the original article was published in a journal that is indexed in MEDLINE. Process to manage the research and publication misconduct.

Managing Cases of Research and Publication Misconduct

When the journal faces suspected cases of research and publication misconduct—such as a redundant (duplicate) publication, plagiarism, fabricated data, changes in authorship, undisclosed conflicts of interest, ethical concerns with the submitted manuscript, appropriation of an author’s idea or data by a reviewer, complaints against the editors, and other issues— it conducts a resolution process, which follows the flowchart provided by the Committee on Publication Ethics (http://publicationethics.org/resources/flowcharts). The editorial board shall discuss suspected cases and reach a decision. Any manuscripts that do not follow the guidelines for research and publication ethics are subject to sanctions, which are to be decided by the editorial board, and may include restriction on future submissions to the journal. Editors who are involved in an article as authors or have any conflict of interest are excluded from the process of peer review and decision making regarding acceptance. If the editor-in-chief is involved, an associate editor takes on the former’s role and makes the final decision on acceptance.

For other policies on research and publication ethics not stated above, the journal follows the policies established by the Good Publication Practice Guidelines for Medical Journals from the Korean Association of Medical Journal Editors (http://www.kamje.or.kr), or the guidelines regarding research and publication ethics from either the International Committee of Medical Journal Editors (http://www.icmje.org) or the Committee on Publication Ethics (https://publicationethics.org/resources/resources-and-further-reading/international-standards-editors-and-authors).

Unit, Nomenclature, and Abbreviations

The SI system should be used for all scientific and laboratory data; if, in certain instances, it is necessary to quote other units, these should be added in parentheses. Temperature should be given in degrees Celsius (°C). Biochemical nomenclature should conform to that recommended by the IUPAC-IUB Commission, and enzymes should be given their EC numbers and systematic names. Abbreviations of chemical or other names should be defined when first mentioned unless commonly used and internationally known and accepted. Where abbreviations are likely to cause ambiguity or may not be readily understood by an international readership, units should be presented in full.

Statistics

Manuscripts reporting analytical, biological activity, composition, and related data must include relevant statistical information to support discussion of differences or similarities in data sets. Describe all statistical tests utilized and indicate the probability level (P) at which differences were considered significant. Where data are presented in the text, state what they represent (e.g., means±SEM). Indicate whether data were transformed before analysis. Specify any statistical computer programs used.

Use of the Term ‘Sex/gender’

Please ensure the correct use of the terms, sex (i.e., when reporting biological factors) and gender (i.e., identity, psychosocial or cultural factors), and, unless inappropriate, please report the sex and/or sex of the study participants, the sex of animals or cells, and describe the methods used to determine sex and gender. Authors should provide a justification for conducting studies on exclusive populations (e.g., those involving only one sex), except in obvious cases (e.g., prostate cancer).

Screening before Review

Peer review is used to help ensure the highest possible quality in published manuscripts. Scientists with expertise in the subject matter will evaluate the manuscript for validity of the experimental design and results, originality, significance, and appropriateness to the Journal. The Editors may exercise their prerogative to decline a manuscript without peer review if that paper is judged to be outside the aims and scope of the Journal, poorly written or formatted, fragmentary and marginally incremental, or lacking in significance. All manuscripts submitted are reviewed and handled by the Editor-in-Chief or assigned to one of the Editors. The Editors are then responsible for the assigned manuscripts, including evaluating the content and format of the paper, selecting reviewers, monitoring the progress of the double-blind review process, evaluating the comments of reviewers and forwarding them to the authors for their response, communicating ultimate acceptance or rejection to the corresponding author, and carrying out a final check of accepted manuscripts for appropriate format and style.
If the manuscript does not fit the aims and scope of the Journal or does not adhere to the Instructions to authors, it may be returned to the author immediately after receipt and without a review. All submitted manuscripts are inspected anytime during the peer-review processes by Similarity Check powered by iThenticate (https://www.crossref.org/services/similarity-check/), a plagiarism-screening tool. If a too high a degree of similarity score is found, the Editorial Board will do a more profound content screening. The criterion for similarity rate for further screening is usually 30%; however, the excess amount of similarity in specific sentences may be also checked in every manuscript. The settings for Similarity Check screening are as follows: It excludes quotes, bibliography, small matches of 9 words, small sources of 1%, and the Methods section.

Peer Review Process

Typically, two reviewers are selected per paper on the basis of the subject matter, available expertise, and the Editor’s knowledge of the field. Reviewers are normally asked to provide their assessments within two to three weeks. Anonymous copies of the reviews and the Editor’s decision regarding the acceptability of the manuscript are sent to the corresponding author. If the reviewers’ evaluations of the manuscript disagree, or if reviewer’s and Editor’s comments are not satisfactorily addressed by the authors, the Editor may reject the manuscript or select additional reviewers. These additional reviews are used by the Editor to assist in reaching the final decision regarding disposition of the manuscript.

Proofs

Authors are responsible for ensuring that all manuscripts (whether original or revised) are accurately typed before final submission. Proofs are sent to the corresponding author(s) before publication and should be returned within 48 hours of receipt. The publishers reserve the right to charge for any changes made at the proof stage (other than printer’s errors) since the insertion or deletion of even a single word may necessitate the resetting of whole paragraphs.

Feedback after Publication

The authors or readers could inform the Editorial Board regarding any errors or content that should be revised. The Editorial Board may consider the erratum, corrigendum, or retraction. If there are any revisions to the article, there will be a CrossMark description to announce the final draft. Any reader’s opinion on the published article in the form of a letter to the editor will be forwarded to the authors. The authors may reply to readers’ letters. Subsequently, the letter to the editor and the author’s reply may also be published.

Process for Appeals

The policy of the journal is primarily aimed at protecting the authors, reviewers, editors, and publishers of the journal. Appeals may be submitted to office@pnfs.or.kr. Appeals received by the editorial office are discussed by the editorial board members, and the results are subsequently dispatched to the submitter. The process of handling complaints and appeals follows the guidelines of the Committee of Publication Ethics (https://publicationethics.org/appeals).

The submissions of a manuscript and peer-review process are free of charge. The processing fee applies only to manuscripts accepted for publication. Authors will be invoiced by the publisher for printed pages. The authors can download the PDF file on the journal web page, and offprints can be ordered at current printing prices. The corresponding author should pay the page charge via wire transfer (Bank: Kookmin bank, Account: The Korean Society of Food Science and Nutrition 833601-00-018417) as follows: KRW 30,000 for each printed page for domestic members and exemption for authors based outside the Republic of Korea.

The full text of PNF has been archived in PubMed Central (PMC) since its 17th volume was published in 2012 and also in National Library of Korea (http://www.nl.go.kr). According to the deposit policy (self-archiving policy) of Sherpa/Romeo (http://www.sherpa.ac.uk/), authors cannot archive pre-prints (i.e., pre-refereeing); however, they can archive post-prints (i.e., final draft postrefereeing). Authors can also archive the publisher’s version/PDF. PNF provides electronic backups and preservation of access to the journal content in the event that a journal is no longer published by archiving in PubMed Central.
