Instruction to Authors



2019 January last updated
KjG is the official journal of The Korean Society of Gastroenterology, published monthly. The Journal publishes original articles of clinical and fundamental researches on gastrointestinal tract, liver, and pancreatobiliary tract, to contribute further development of gastroenterology. This regulation is revised based on the "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" developed by the International Committee of Medical Journal Editors (http://www.icmje.org) and are supplemented ethical principles and rules for references.


1. TYPES OF MANUSCRIPT
1) The types of manuscripts include editorials, original papers, review articles, case reports, image of the month, research update, brief communications, and letters to the editor.
2) Review articles, image of the month, and research update are limited to manuscripts solicited by the editorial board.


2. LANGUAGE OF MANUSCRIPT
1) All manuscripts must be in either Korean or English. Hangul (.hwp) or MS Word (.doc) may be used for Korean manuscripts, and MS Word for English manuscripts. The manuscripts must be double-spaced in A4 size.
2) The glossary issued by Korean Medical Association shall apply for the use of medical terms in Korean manuscripts. If translations in Korean are not available, such as for proper nouns, names of medicine, and units, English may be used in Korean manuscripts. If translations are likely to cause confusions, the term should be presented in its original language in parentheses at the first appearance, and then only translated term should be used.
3) For English abbreviations, authors can refer to the "list of English abbreviations" provided by the journal. Other abbreviations, which are not listed on it, and used for 3 times or more must be defined at the first mention in the text using parentheses.


3. SUBMISSION OF MANUSCRIPT

1) Apply for publication
All manuscripts must be submitted through the online submission system of the Society's website (http://www.gastrokorea.org). The peer review afterward is conducted through the system as well.
Authors should read carefully the checklist posted on the Society's website and submit after checking each items. There is no submission fee.
Only the first author and/or corresponding author can submit the manuscript through the online system.
The decision to publish will be made by the editorial board of the journal after the peer review. The board has the right to reject and demand the revision of the submitted manuscripts if the board believes that the manuscripts do not stand to the rules of the regulations.
The editorial board has the right to revise and edit the styles and structures of submitted manuscripts within the context if necessary.

2) Authorship and copyright
As stated in the ICMJE recommendations, credit for authorship requires (a) substantive intellectual contributions to the basic conception and design, or collection/analysis/interpretation of data, (b) the drafting and/or revising the article, or (c) the final approval of the version to be published.
Upon the submission of manuscripts, all authors must sign and submit the "Copyright Transfer Agreement Form", and it is not allowed to change the first or corresponding author, or to add or remove co-author(s) once the manuscript is submitted to the Society.
The Copyright Transfer Agreement Form must be submitted via mail (to the main office of the Society), fax, or e-mail as scanned file.
The editorial board may return the submitted manuscripts if they are not correctly composed according to the "checklist" for technical reasons. Authors should revise their manuscripts according to the regulations before resubmission.
Authors should clearly identify the fact that there is conflict of interest, if any, related to the submitted articles.

3) Principles on overlapping publication
The Society do not accept any manuscripts that are identical or significantly similar to studies already published or going to be published in other journals.
It is not allowed for authors to publish their articles already appeared in KjG without permission from the board. Multiple or duplicate publication is only limited to the cases specified in the Uniform Requirements for Manuscripts Submitted to Biomedical Journals (Ann Intern Med 1997; 126:36-47). This does not apply to the publication of abstracts or posters.
Authors are subject to penalties and/or unfavorable outcomes if unauthorized duplicate publication is discovered.


4. ETHICAL CONSIDERATIONS
1) When reporting experiments on human subjects, authors who submit manuscripts to KjG should acquire the permission from the ethical committee on human experiment and indicate all possible physical and psychological damages on subjects and/or their guardians before the experiment is conducted, in accordance with the Helsinki Declaration of 1975.
2) Any information that could have revealed subjects' identities, such as name and initials, should not appear in the text. If a photo is presented, proper measures should be taken not to reveal the subject's identity, or a written consent must be presented for the photo and possible disclosure of subject's identity.
3) When reporting experiments on animals, authors should describe the measures they have taken to ease pains and inconvenience on the subjects, and indicate whether the NIH Guide for the Care and Use of Laboratory Animals or corresponding guideline was followed.
4) For unspecified yet necessary guidelines on the issues of legitimacy and ethics on the submitted manuscripts, authors may consult the International Standards for Editors and Authors by the Committee on Publication Ethics (COPE), which is available at http://publicationethics.org/resources/international-standards-for-editors-and-authors.
5) When malpractices are found in the article submitted to this journal, KjG will follow the flowcharts by the COPE (http://publicationethics.org/resources/flowcharts) for settlement of any misconduct.
6) Description of sex or gender of study subjects: Ensure correct use of the terms sex (when reporting biological factors) and gender (identity, psychosocial or cultural factors), and unless inappropriate, report the sex or gender of study participants, the sex of animals or cells, and describe the methods used to determine sex or 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).


5. REVIEW OF MANUSCRIPT
1) The Editor-in-Chief reviews all submissions and makes an initial determination regarding suitability for peer review.
2) All manuscripts undergo peer review by at least two reviewers with relevant expertise who are selected by the editorial board.
3) The editors make the final decision of publication based on the result of peer review.
4) Once the decision on publication as accept, revision or reject is made, it is directly noticed to the corresponding author. After the final draft of the manuscript is proven to be appropriate according to the publication policies and styles of the journal, the decision of publication is finalized and expected publication date will be given. Rejected manuscripts are not to be considered again.
5) After the decision, revised manuscripts should be submitted usually within 8 weeks for original articles, and 4 weeks for case reports, otherwise it may be decided to be rejected.
