Instruction for Authors

1. General Information

• The Journal of The Korean Data Analysis Society (JKDAS) is the official journal of the Korean Data Analysis Society (KDAS). Researchers, practitioners, and policymakers who wish to submit a manuscript are strongly encouraged to read the Aims and Scope section of this journal carefully. Manuscripts should be prepared in accordance with the submission guidelines of JKDAS as outlined below.
• JKDAS also fully adheres to the Principles of Transparency and Best Practice in Scholarly Publishing, as outlined in the joint statement by COPE, DOAJ, WAME, and OASPA (http://doaj.org/bestpractice).

2. Copyright and Creative Commons Attribution License

• Upon publication, the journal acquires ownership of all submitted manuscripts. JKDAS retains the copyright for all published materials. Additionally, all content is licensed under the Creative Commons Attribution License (CC BY), available at http://creativecommons.org/licenses/by/4.0/.
• Authors are responsible for the accuracy of all content within their papers and are required to complete the Copyright Transfer Agreement, which must be submitted to JKDAS.

• Authors may post the final accepted version or the published version of their articles on personal websites, institutional repositories, or other non-commercial platforms, provided that proper citation to the original publication in JKDAS and the CC BY 4.0 license are clearly indicated.

3. Research and Publication Ethics

• The journal follows ethical guidelines for research and publication outlined in the Guidelines on Good Publication (https://publicationethics.org/guidance) and the ICMJE Guidelines (http://www.icmje.org).

3.1. Authorship

• Authorship credit should be determined based on the following criteria: 1) significant contributions to the conception, design, data acquisition, and/or data analysis and interpretation; 2) drafting the article or critically revising it for substantial intellectual content; 3) granting final approval for the version to be published; and 4) agreeing to be responsible for all aspects of the work, ensuring thorough investigation and resolution of inquiries regarding the accuracy or integrity of any part of the research. Each author is required to satisfy all four conditions.
• Following the initial manuscript submission, any alterations in authorship, such as adding or removing authors, or rearranging the author order, must be elucidated through a letter to the editor submitted by the concerned authors. This letter must bear the signatures of all authors involved.
• Corresponding author and first author:
  JKDAS does not allow multiple corresponding authors for one article. Only one author should correspond with the editorial office and readers for one article. JKDAS does accept notice of equal contribution for the first author when the study was clearly performed by co-first authors.
• Authorship corrections post-publication will only be addressed by JKDAS in cases where errors are attributed to the editorial staff. Changes to authorship can be made before publication, following submission, if all authors associated with the manuscript request such corrections.

3.2. Originality, Plagiarism and Duplicate Publication

• Manuscripts submitted for review should not have been previously published or be concurrently under consideration elsewhere. Permission from the Editorial Board is required for any replication of accepted manuscript content in another scientific journal. Upon submission, manuscripts undergo screening for potential plagiarism or duplicate publication through Similarity Check. If instances of plagiarism or duplicate publication are identified, the manuscripts may be rejected, the authors publicly disclosed in the journal, and their respective institutions informed.
• Authors must obtain prior permission, typically in the form of a letter, for the utilization of any previously published material. It is the responsibility of the authors to secure permission from the publisher for the reproduction of any material, including text, figures, and tables.

3.3. Conflict of Interest Statement

• The corresponding author is required to disclose to the editor any possible conflicts of interest that may impact the authors' interpretation of the data. Examples of potential conflicts of interest include financial backing from or affiliations with companies, political influences from interest groups, and academically related matters. It is especially important to explicitly mention all sources of funding relevant to the study.

3.4. Statement of Human and Animal Right

• Clinical research must adhere to the Ethical Principles for Medical Research Involving Human Subjects as outlined in the 1975 Helsinki Declaration, which can be accessed at: https://www.wma.net/policies-post/wma-declaration-of-helsinki-ethical-principles-for-medical-research-involving-human-subjects/. Clinical studies that do not align with the Helsinki Declaration will not be considered for publication. To safeguard the privacy of human subjects, identifiable information, such as patients' names, initials, hospital numbers, dates of birth, or other protected healthcare information, should not be disclosed. When involving animal subjects, research should be conducted following the National or Institutional Guide for the Care and Use of Laboratory Animals, ensuring the ethical treatment of all experimental animals.

3.5. Statement of Informed Consent and Institutional Review Board Approval

• Records of written informed consent documents must be retained for research involving human subjects, particularly those containing identifiable or sensitive information. Clinical studies involving human subjects necessitate a certificate, agreement, or approval from the Institutional Review Board (IRB) of the author's institution. In instances where clarification is needed regarding IRB approval and study conduct, the editor or reviewers may request copies of these documents.

3.6. 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 (https://publicationethics.org/guidance?f%5B0%5D=type%3A16). The discussion and decision on the suspected cases are carried out by the Editorial Board.

3.7. Editorial Responsibilities

• The Editorial Board will consistently strive to oversee and uphold publication ethics, including guidelines for article retractions, maintaining the integrity of the academic record, preventing business considerations from compromising intellectual and ethical standards, issuing corrections, clarifications, retractions, and apologies as necessary, and preventing plagiarism and fraudulent data. The editors bear responsibilities such as the authority to accept or reject articles, avoiding conflicts of interest concerning accepted or rejected articles, advocating for the publication of corrections or retractions in case of errors, and preserving the anonymity of reviewers.

3.8. Appeals and Reconsideration Process

• If an author objects to the editorial decision regarding the publication of a submitted manuscript, the author may submit a formal written request for reconsideration to the Editorial Board within 30 days of receiving the decision notice. The appeal letter should clearly describe the reasons for disagreement and provide supporting evidence or explanations.
• Upon receiving the request, the Editorial Board will review the case and, if necessary, appoint five independent reviewers with appropriate expertise who were not involved in the initial evaluation. The final decision will be made by majority vote based on the reviewers’ recommendations and the Editorial Board’s deliberation.
• If a paper is re-reviewed and accepted as publishable, it cannot be published in the same issue or volume as the original decision. A new set of reviewers will be appointed for the re-review process to ensure fairness and objectivity.
• Papers that have been deemed not publishable by three or more reviewers, or have already undergone reconsideration or re-review, cannot be resubmitted for further appeal.

3.9. Data Sharing and Reproducibility

• JKDAS encourages transparency and reproducibility in all published research. Authors are strongly recommended to make the data supporting their findings available in a public data repository or to provide it upon reasonable request.
• When data cannot be shared due to ethical, legal, or privacy considerations, authors must clearly state this in the manuscript.
• All submissions should describe the methods used for data collection, processing, and analysis in sufficient detail to allow replication by other researchers.
• The Editorial Board may request access to the underlying data for verification during the review or post-publication process if necessary.

3.10. Intellectual Property

• JKDAS recognizes and respects the intellectual property rights of authors and contributors. Upon acceptance of a manuscript, authors grant to the Journal of the Korean Data Analysis Society (JKDAS) the right to publish, distribute, and archive the article in all forms and media. JKDAS retains the copyright for all published materials; however, authors preserve their moral rights and the right to reuse their work in accordance with the Creative Commons Attribution License (CC BY 4.0), available at http://creativecommons.org/licenses/by/4.0/ Authors are responsible for ensuring that all materials included in their manuscript - such as text, figures, tables, or datasets - do not infringe upon any existing copyright, trademark, patent, or other intellectual property rights. If any part of the work has been previously copyrighted, patented, or includes third-party material, authors must obtain and provide written permission from the rights holder prior to submission. JKDAS allows authors and third parties to use, share, and reproduce published content for non-commercial and educational purposes, provided that appropriate credit is given to the original publication and license terms are observed. Any disputes or claims regarding intellectual property will be handled by the Editorial Board in accordance with the Committee on Publication Ethics (COPE) guidelines.

3.11. Post-publication Discussions and Corrections

• JKDAS provides mechanisms for maintaining the accuracy and integrity of the academic record after publication. If significant errors, ethical concerns, or issues affecting the interpretation of published articles are identified, authors or readers may contact the editorial office (jkdas.office@gmail.com) to request a correction, retraction, or expression of concern. The Editorial Board will review such requests in accordance with the Committee on Publication Ethics (COPE) guidelines and, when necessary, publish corrections, retractions, clarifications, or editorial notes.
• JKDAS also welcomes scholarly discussions or comments related to published papers. Substantive post-publication discussions that contribute to academic discourse may be published as Letters to the Editor or Editorial Comments at the discretion of the Editorial Board. All post-publication updates, including corrections and retractions, are clearly linked to the original article to ensure transparency.

3.12. Archiving

• JKDAS ensures long-term electronic preservation and public access to all published content. All articles are permanently archived and accessible through the Korea Citation Index (KCI) managed by the National Research Foundation of Korea (NRF) and the DBpia digital platform. These repositories guarantee continued access to published articles even in the event that the journal is no longer published. In addition, metadata of all published articles are stored in multiple secure databases to ensure digital preservation and redundancy.

3.13. Revenue Sources

• JKDAS is a non-profit journal published by the KDAS. The journal’s operations are supported by author publication fees, membership fees, and institutional support from KDAS. No advertising or commercial sponsorship is used as a source of revenue. All publication fees are clearly stated in the “Submission and Publication Charges” section of this document. The Editorial Board ensures that financial considerations do not influence editorial decisions regarding manuscript acceptance, peer review, or publication outcomes.

3.14. Advertising Policy

• JKDAS does not publish or accept any commercial advertisements, sponsorships, or promotional content. The journal is fully supported by author publication fees, membership fees, and institutional support from the KDAS. No advertising content or sponsorships influence editorial decisions, peer review, or the publication process.

3.15. Direct Marketing

• JKDAS does not conduct any aggressive or misleading direct marketing activities. All calls for papers and promotional communications are made only through the official website of the KDAS or verified academic channels. Information about the journal, including its aims, scope, and review process, is accurate and not intended to mislead authors or readers.

4. Submission and Peer Review Process

4.1. Submission

• All manuscripts should be submitted via e-submission system available from: https://www.dbpiaone.com/kdas/. If any authors have difficulty in submitting via e-submission system, please send a manuscript to jkdas.office@gmail.com by the corresponding author.

4.2. Peer Review Process

• JKDAS reviews all manuscripts received. A manuscript is first reviewed for its format and adherence to the aims and scope of the journal. If the manuscript meets these two criteria, it is checked for plagiarism or duplicate publication with Similarity Check. After confirming its result, it is dispatched to investigators in the field with relevant knowledge. Assuming the manuscript is sent to reviewers, JKDAS waits to receive opinions from at least three reviewers. In addition, if deemed necessary, a review of statistics may be requested. The acceptance criteria for all papers are based on the quality and originality of the research and its scientific significance. Acceptance of the manuscript is decided based on the critiques and recommended decision of the reviewers. An initial decision will normally be made within 4 weeks of receipt of a manuscript, and the reviewers’ comments are sent to the corresponding author by email. 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 3 months of the editorial decision is regarded as a withdrawal. A final decision on acceptance/rejection for publication is forwarded to the corresponding author from the editor-in-chief.
