Journal of Rheumatic Diseases (JRD) is the official journal of the Korean College (KCR) of Rheumatology and the Korean College of Pediatric Clinical Immunology. Anyone who would like to submit a manuscript is advised to carefully read the aims and scope section of this journal. Manuscripts should be prepared for submission to JRD according to the "Information to Author". 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" (http://www.icmje.org).
Compliance with ICMJE Recommendations: The journal adheres completely to the ethical guidelines for research and publication described in Guidelines on Good Publication (http://publicationethics.org/resources/guidelines), the ICMJE Guidelines (http://www.icmje.org), and Principles of Transparency and Best Practice in Scholarly Publishing (joint statement by COPE, DOAJ, WAME, and OASPA; (http://doaj.org/bestpractice).

• 1) Conflict-of-Interest statement
  Conflict of interest exists when an author or the author's institution, reviewer, or editor has financial or personal relationships that inappropriately influence or bias his or her actions. These relationships vary from being negligible to having great a potential for influencing judgment. Not all relationships represent true conflict of interest. On the other hand, the potential for conflict of interest can exist regardless of whether an individual believes that the relationship affects his or her scientific judgment. Financial relationships such as employment, consultancies, stock ownership, honoraria, and paid expert testimony are the most easily identifiable conflicts of interest and the most likely to undermine the credibility of the journal, the authors, or of the science itself. Conflicts can occur for other reasons as well, such as personal relationships, academic competition, and intellectual passion (http://www.icmje.org/conflicts-of-interest/). If there are any conflicts of interest, authors should disclose them in the manuscript. The conflicts of interest may occur during the research process as well; however, it is important to provide disclosure. If there is a disclosure, editors, reviewers, and reader can approach the manuscript after understanding the situation and background for the completed research. A potential conflict of interest should be disclosed in the manuscript even when the authors are confident that their judgments have not been influenced in preparing the manuscript. The disclosure form should be the same as the International Committee of Medical Journal Editors (ICMJE) Uniform Disclosure Form for Potential Conflicts of Interest (http://www.icmje.org/conflicts-of-interest/).
• 2) Statement of human and animal right
  Clinical research should be done in accordance with the Ethical Principles for Medical Research Involving Human Subjects, as outlined in the Helsinki Declaration of 1975 (revised 2013) (available from: https://www.wma.net/policies-post/wma-declarationof-helsinki-ethical-principles-for-medical-research-involvinghuman-subjects/). Clinical studies that do not meet the Helsinki Declaration will not be considered for publication. For publication, the human subjects' identifiable information, such as the patients' names, initials, hospital numbers, dates of birth, or other protected healthcare information should not be disclosed. For animal subjects, the research should be performed based on the National or Institutional Guide for the Care and Use of Laboratory Animals, and the ethical treatment of all experimental animals should be maintained.
• 3) Statement of informed consent and Institutional Review Board approval
  Copies of written informed consents should be kept for studies on human subjects. For the clinical studies with human subjects, there should be a certificate, an agreement, or the approval by the Institutional Review Board (IRB) of the author's affiliated institution. If necessary, the editor or reviewers may request copies of these documents to resolve questions about IRB approval and study conduct.
• 4) Registration of the clinical research and data sharing policy
  Any research that deals with clinical trial should be registered to the primary national clinical trial registration site such as http://cris.nih.go.kr/cris/index.jsp, or other sites accredited by World Health Organization or ICMJE.
  This journal follows the data sharing policy described in "Data Sharing Statements for Clinical Trials: A Requirement of the International Committee of Medical Journal Editors". The ICMJE's policy regarding trial registration is explained at http://www.icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial-registration.html. If the data sharing plan changes after registration this should be reflected in the statement submitted and published with the manuscript, and updated in the registry record.
• 5) Authorship
  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; 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 4 conditions. If any persons who do not meet the above four criteria, they may be placed as contributors in the Acknowledgments section. Description of co-first authors or co-corresponding authors is also Enacted January 10, 1994 Recently revised October 13, 2022 accepted if the corresponding author believes that such roles existed in contributing to the manuscript. If authors request removal or addition of an author after manuscript submission or publication, journal editors should seek an explanation and signed statement of agreement for the requested change from all listed authors and from the author to be removed or added.
• 6) Originality and duplicate publication
  All submitted manuscripts should be original and should not be in consideration by other scientific journals for publication. Any part of the accepted manuscript should not be duplicated in any other scientific journal without the permission of the Editorial Board, although the figures and tables can be used freely if the original source is verified according to Creative Commons license. It is mandatory for all authors to resolve any copyright issues when citing a figure or table from other journal that is not open access.
  
• 7) Secondary publication
  It is possible to republish manuscripts if the manuscripts satisfy the condition of secondary publication of the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals by International Committee of Medical Journal Editors (ICMJE), available from http://icmje.org/recommendations/. These are:
  
  • • 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).
  • • The priority for the primary publication is respected by a publication interval negotiated by editors of both journals and the authors.
  • • The paper for secondary publication is intended for a different group of readers; an abbreviated version could be sufficient.
  • • The secondary version faithfully reflects the data and interpretations of the primary version.
  • • The secondary version informs readers, peers, and documenting agencies that the paper has been published in whole or in part elsewhere—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.
  • • 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 to be "republications" and does not cite or index them when the original article was published in a journal that is indexed in MEDLINE.
• 8) Process to manage the 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, an ethical problem discovered with the submitted manuscript, a reviewer who has appropriated an author's idea or data, complaints against editors, and other issues, the resolving process will be followed by flowchart provided by the Committee on Publication Ethics (http://publicationethics.org/resources/flowcharts). The discussion and decision on the suspected cases are done by Editorial Board of JRD.

It is not allowed for another journal to publish a manuscript that is the same as or similar to that submitted to the JRD. In addition, the KCR possesses the copyright of a manuscript whose publishing has been decided and is authorized to publish, distribute or print the manuscript in the JRD or other media.

We accept submissions only through our online manuscript submission system (https://www.editorialmanager.com/jrds/). Please do not submit manuscripts as electronic mail attachments or by regular mail.

Every manuscript submitted should be peer-reviewed by two or more relevant experts (3 most relevant investigators available for review of the original article and case report), as regards the appropriateness of publishing. Its publishing should be decided on the basis of the deliberation and its author may be advised to revise or complement its content. Advised to revise its content, the author should revise the manuscript and submit the revised manuscript along with his/her answer on the processing of the items pointed out by judges in a file form.
The revised manuscript should be resubmitted via the web system. Failure to resubmit the revised manuscript within 2 months without any notice from the corresponding author is regarded as a withdrawal.

The original article should contain, in the following order: title page, abstract, keywords, running title, main text (introduction, materials and methods, results, discussion, conclusion), supplementary data, funding, acknowledgments, conflict of interest, author contributions, ORCID, references, tables and figures.

• 1) Title page: The title page should list the article type, article title, author information including names, their affiliations, and their academic degrees (M.D., Ph.D., etc.), corresponding author information, and any conflict of interest. The page should be uploaded separately from main text. The title should be short (30 or fewer words), informative, and contain the major keywords. The use of acronyms and abbreviations should be avoided. A running title must also be provided, and should be 10 or fewer words. Contact information for correspondence must be provided, consisting of the name, address (institutional affiliation, city, zip code, and country), ORCID number (ORCID, Open Researcher and Contributor ID; http://orcid.org), and e-mail address. If screening is in process after submission, it is impossible to add any other author or delete any of the authors or change the order in which they are placed. When adding a manuscript file, make sure that it does not include any content that hints at any author or institution in the main text.
• 2) Abstract: The abstract should be between 150 and 250 English words. It should be written concisely and clearly using specific data as per the prescribed form divided into four items, i.e. objective, methods, results, and conclusion. Specify 2 to 5 medical subject headings (MeSH) (http://www.ncbi.nlm.nih.gov/sites/entrez?db=mesh), which correspond to the contents of manuscript and are registered in the Index MEDICUS, in order of importance at the bottom of the English abstract. Abbreviations must be defined at the first mention in the abstract using parentheses.
• 3) Main text:
  
  • ① Introduction: The introduction should present study objectives simply and clearly and include only the contents related to the objectives when describing backgrounds.
  • ② Materials and Methods: Describe the plan, objects and methods of study. Specify in detail how to select and observe subjects. Describe the methods of test specifically so that other investigators can reenact the test. When reporting experiments with human or animal subjects, the authors should indicate whether they received approval from the Institutional Review Board (IRB) for the study.
    Ensure correct use of the terms sex (when reporting biological factors) and gender (identity, psychosocial or cultural factors), and, unless inappropriate, report the sex and/or gender of study participants, the sex of animals or cells, and describe the methods used to determine sex and gender. If the study was done involving an exclusive population, for example in only one sex, authors should justify why, except in obvious cases (e.g., prostate cancer). Authors should define how they determined race or ethnicity and justify their relevance.
  • ③ Results: This section should be presented clearly and logically and should make a statistical treatment in the biological measurement in which there are many changes in measured values. When using tables, do not overlap table contents in the text, but describe important trends and key points.
  • ④ Discussion: Take study results into consideration and interpret them in connection with other data. Emphasize new and important observations and do not overlap the contents of results. Describe the meanings and limitations of observations and connect conclusions with study objectives within the scope the results admit.
  • ⑤ Conclusion: Specify the significances and conclusions of study simply.
• 4) Funding: Financial support, including foundations, institutions, pharmaceutical and device manufacturers, private companies, or intramural departmental sources, or any other support should be described.
• 5) Acknowledgments: Persons or institutes who contributed to the papers but not enough to be coauthors may be introduced.
• 6) Conflict of Interest
• 7) Author's Contributions: Authors must include a statement to specify the contributions of each co-author. The statement can be up to several sentences long, describing the specific contributions made by each author (list the authors' initials, e.g., ABC). The name of each author must appear at least once in any of the following categories; conception and design of study, acquisition of data, analysis and/or interpretation of data, drafting the manuscript, revising the manuscript critically for important intellectual content.
• 8) References
• 9) Tables and Figures

• 2) Draw up a manuscript in proper and clear English. If you are not a native English speaker, we strongly recommend that you have your manuscript professionally edited before submission.
• 3) Use the International System of Units (SI) for the test value units in a test room. You may add the SI values in parentheses as per the requests or necessities of the Publication Committee. For liter, use a capital letter L.
• 4) It is desirable to minimize the use of abbreviations, if possible. But if it is unavoidable to use their abbreviations due to the repetitive use of specific terms in text, enter the abbreviations in parentheses when the terms appear for the first time and then use the abbreviations.
  ex) Systemic lupus erythematosus (SLE)
  Parvovirus B19 (PVB19)
• 5) Put a space before the opening parenthesis, and either a space or a punctuation mark after the closing parenthesis.
• 6) When specifying a machine or device, enter its model name, manufacturer, city or state and nationality in parentheses. For a reagent, it is a principle to use its general name, but its product name may be entered in a parenthesis. When using the product name, enter its manufacturer, city or state and nationality in parentheses.

• 1) Citation of references is recommended preferentially in a new page and place Arabic numerals in order of citation.
• 2) All the references should be listed in the order of citation in the text, in English. When inserting citation in the text, enter their numbers in brackets and when 3 or more references are placed in succession, enter only the first and last numbers, with "-" placed between them (ex. Wilson suggested [1-3]). When a cited reference has one, two and three authors, refer to them as "A", "A and B" and "A et al." respectively.
• 3) Do not list any reference unpublished in the references. If it is unavoidable to quote it, enter "personal opinion exchanges" or "unpublished material" in parentheses.
• 4) Specify the name of an academic journal using an approved abbreviation from the Index Medicus. Even if the journal is domestically published, specify its name in English.
• 5) Author(s)' name should be listed as surname first and the initials of first and middle name second. If there are 6 or fewer authors, specify all of their names and if there are 7 or more authors, add et al. after 6 names.
• 6) Specify the first and last pages of a reference.
• 7) Original articles should cite 40 references or fewer and case reports should cite 15 references or fewer.
