This statement clarifies the ethical of all parties involved in the act of publishing articles in this journal, including authors, editor-in-chief, editorial board, peer-reviewers and publishers. This statement is based on COPE's Best Practice Guidelines for Journal Editors.


General Guidelines

1. Reported research must be conducted in an ethical and responsible, and must comply with all relevant laws.

2. Authors must present results in a clear, honest, without fabrication, falsification or manipulation of data.

3. Authors must explain their research method clearly and unequivocally so that their findings can be confirmed by others.

Responsible research publication


1. Strength and reliability

Reported research must be conducted in an ethical and responsible manner and in compliance with all relevant laws. Reported research must be carried out carefully. Researchers should use appropriate methods of analysis and data presentation (seek and follow expert advice on this subject if necessary). Authors must take collective responsibility for their publication. Researchers should check their publications carefully at every stage to ensure methods and findings are reported accurately.


2. Honesty

Researchers must present data honestly without fabricating, falsifying or manipulating data. Images should not be modified to give misleading results. Researchers must describe the methods they used and present their findings in a clear and unambiguous. Researchers must follow applicable reporting guidelines. Publications should provide sufficient detail to allow the experiment to be repeated by other researchers. The research report must be complete. The reviewer should not dismiss untoward, inconsistent or unexplained findings or results that do not support the authors 'or sponsors' hypotheses or interpretations.

Research sponsors cannot veto publication of findings that do not support their product or position. Researchers should not enter into agreements allowing research sponsors to veto or control the publication of findings (unless there are exceptional circumstances, such as research closed by the government for security reasons).

Authors should immediately notify editors if they find errors in work submitted, received or published. Authors must cooperate with editors in issuing corrections or repeal of articles, if necessary. Authors must refer to other people's work accurately in citations. Authors may not copy references from other publications if they have not read the work cited.


3. Balance

New findings must be presented in the context of previous research. The work of others must be presented fairly. Scientific review and synthesis of previous studies should be complete, balanced, and should include findings regardless of whether they support the proposed hypothesis or interpretation. Editorials or opinions that convey a single point of view or argument that must be clearly distinguished from scientific reviews. The limitations of the research must be stated in the publication.


4. Originality

Authors must follow the publication requirements that the work published is original and has not been published elsewhere in any language. Submissions may not be submitted simultaneously to more than one journal unless the editor has agreed to joint publication. If the article is published together, this should be made clear to the reader.

Applicable copyright laws and regulations must be followed. Copyright material (tables, figures or quotes) must be reproduced with appropriate permission and acknowledgment.

Relevant previous works and publications by other authors must be appropriately acknowledged and referenced. Citations should come from the original reference.

Data, text, numbers, or ideas originating from other researchers must be referenced correctly, and should not be presented as if they were the author's own. Original words taken directly from another researcher's publication must appear in quotation marks with the correct citation.

The author should inform the editor if the findings have been previously published or if multiple reports or some analyses of one dataset are under consideration for publication elsewhere. Authors must provide copies of related publications or submitted works to other journals.

Multiple publications arising from a research project must be clearly identified and the main publication referred to. Translations and adaptations for different readers should be clearly identified. Original sources must be identified, copyright regulations must be respected. When in doubt, authors should seek permission from the original publisher prior to republishing the work.


5. Transparency

All sources of research funding, including direct and indirect financial support, procurement of equipment or materials, and other support (such as statisticians or co-authors) should be identified.

Authors must disclose the role of the research funder or sponsor (if any) in the design, implementation, analysis, interpretation and reporting of the research. Authors must disclose any relevant financial and non-financial interests and relationships that may be considered likely to influence the interpretation of their findings or that the editor, reviewer or reader may want to know. This includes relationships with journals, for example if editors publish their own research in their own journals. In addition, authors must follow journal requirements and institutional requirements to declare a conflict of interest.


6. Author Contribution

Research publication authors must accurately reflect each individual's contribution to the article.

Top contributors must be listed as authors, while persons who make less substantial, or purely technical contributions, either to the study or to publication are listed in the award section (acknowledgement). The criteria as author or award (acknowledgement) must be approved from the start of the project.

Researchers must ensure that only persons who meet authorship criteria (have a substantial contribution to the research work) are rewarded with 'authorship' and that authors with worthy contributions are not anonymized. Journal agencies and editors should prevent guest, gift, and ghost authorship.


-guest authorship (guest writers) are those who do not meet the criteria as authors but are listed because of seniority, reputation or influence

-Gift authorship are those who do not meet the criteria as authors but are listed for personal support or in exchange for payment

-ghost authorship are those who meet the criteria as an author but are not listed

All authors must agree to be named and must approve the versions sent and received for publication. Changes to the list and author order must be approved by all authors, including those who have been removed from the list. The correspondence writer should act as a point of contact between the editor and other authors. He must liaise with other authors and involve them in major decisions about publication (responding to reviewer comments).

Authors may not use misleading acknowledgments / awards to imply contributions or endorsements by certain individuals who, in fact, were not involved with the work.


7. Accountability and responsibility

All authors must read and understand the articles submitted and follow the principles set out in this manual. Authors are expected to take joint responsibility for the integrity of research and reporting. However, if a particular author is responsible for only certain aspects of the research and articles, then this should be stated.

Authors work closely with editors and publishers to correct them immediately if errors or omissions are found after publication. Authors must respond appropriately to post-publication comments or published correspondence.


8. Compliance with peer review and publication regulations

Authors must follow the publisher's requirement that work is not submitted to more than one publisher at the same time. Authors should inform editors if they withdraw their article from the review, or choose not to respond to reviewer comments. Authors must respond to reviewers' comments in a professional and on time.

Authors must respect the publisher's request for a press embargo, meaning they must not allow their findings to be reported to the press if they have been accepted for publication (but not yet published). Authors and their institutions must work together to coordinate media activities (press releases and press conferences) related to publication. Press releases must accurately refer to works and must not contain statements outside of the research results.


9. Reporting who is responsible for research involving human subjects or experimental animals

Ethical eligibility approval letter and permit or other registration documents must be obtained before the research begins. Details of the letter should be provided in the article, for example the name of the ethics commission and the licensing authority.

If requested by the editor, the author must be able to show evidence of these letters, including proof of consent after the explanation of the research subject.

Researchers should not publish identifiable individual data without the specific consent of the individual (or his guardian).

Researchers must publish all possible research results that contribute to knowledge. In particular, there is an ethical responsibility to publish all clinical trial findings. Publication of failed clinical trials or results that refute the hypothesis may help prevent similar research from being repeated. If the findings from a small study that failed to achieve statistical significance are combined, it is possible to obtain a meta-analysis that is statistically significant and possibly useful.

Authors should provide research protocols to journal editors when requested (for clinical trials) so that reviewers and editors can compare the study report against the protocol to check that the study was carried out as planned and that no relevant details have been ignored. Researchers must follow the relevant clinical trial registration requirements and must include the clinical trial registration number in all publications that emerge from the trial.
