All the manuscripts must comply with the Policies and the Manuscript Formatting Guide of the Journal. The manuscripts must comply with the Aims & Scope of HO CHI MINH CITY OPEN UNIVERSITY JOURNAL OF SCIENCE (hereinafter referred to as the Journal). The manuscript submitted to the Journal must not be published or submitted for publication elsewhere (abstract only or full text; in printed or online version). The manuscript will also be not allowed to submit anywhere else until receiving a final decision from the Journal (rejected for publication). All manuscripts will be checked for plagiarism and research duplication. All documents should be fully cited, listed in the bibliography section. All in-text citations must be thoroughly and comprehensively listed in the reference section. If included in the manuscripts, the participants’ information must have the person’s consent exchanged or discussed. The author is responsible for the content of the article, as well as the use of documents, data, figures, etc. The authors must make all data available upon request to editors and peer reviewers at the time of submission to evaluate the manuscript.

When submitting the manuscript to our Journal, authors must carefully read the policies as follows: 


  1. Authorship criteria

    The author is the individual directly responsible for creating the original article. When two or more individuals collaborate with the intention that their contributions collectively form a complete article, they are referred to as co-authors (hereinafter collectively referred to as authors). Authors encompass a range of individuals, such as researchers, scientists, experts, lecturers, doctor students, and students.

    Author status is determined through the following criteria (McNutt, 2018):

    • Criteria 1: Making significant contributions to research by initiating research ideas or designs, engaging in data collection, analysis, or interpretation, drafting and writing the manuscript, or providing critical review of the content.

    • Criteria 2: Demonstrating agreement and taking responsibility for all edited versions of the manuscript prior to publication.

    • Criteria 3: Consenting to the content and opinions presented in the manuscript, and assuming responsibility for addressing all matters concerning the accuracy and integrity of the research work.

    It is important to note that an individual must satisfy all three of the above criteria to qualify as an author of a scientific article. Authors must be aware that individuals who only contribute to securing funding, provide data, or have leadership roles in research groups will not be eligible for authorship if they do not meet all three of the specified criteria.

  2. Roles of Authors

    Authors submitting manuscripts to the Journal are required to clearly define the roles of the main author, the corresponding author, and co-authors. the order of authors within the article must accurately represent their respective contributions, in accordance with the guidelines established by the Journal:

    • The author whose name appears first on the list of authors in the article is designated as the main author of the article, who plays the main role and directly creates articles..

    • The author whose name appears second on the list serves as the corresponding author and is the designated representative of the author group. This individual is responsible for manuscript submissions, engaging in discussions with the journal, and conveying information to all team members. They ensure the accuracy of member information and the authenticity of the research work's details.

    • The remaining authors are recognized as co-authors, having made substantial contributions to the research such as developing the idea or design, collecting, analyzing, or interpreting data, drafting the manuscript, or critically reviewing its content. Their positioning within the author list reflects the decreasing level of their contributions to the project. 

    To determine the roles and order of authors in the manuscript, the author group must adhere to the following regulations:

    • The number, order, and roles of authors listed in the article must be collectively agreed upon by the author group and must align with the three authorship criteria.

    • Author information, including full names, affiliations (including local and national), and author order in the manuscript, must be consistent with the details provided in the Journal's submission system.

    • The designation of the corresponding author is the responsibility of the author group. The corresponding author is denoted by an asterisk (*) placed next to their name in the manuscript. If the main author is also the corresponding author, they occupy position 1. If the corresponding author is a different individual, they are positioned at number 2. The corresponding author's information, including full name, affiliations (including local and national), and contact email in the manuscript, should match the information declared in the Journal's submission system.

    • The author group is accountable for establishing author status and order in the list before submitting the manuscript to the Journal.

    • Individuals who solely contribute to securing funding, provide data, or lead a research group without meeting the three authorship criteria will be acknowledged in the acknowledgments section.

    • Once the manuscript enters the editing stage, any modifications, deletions, or reordering of author names in the author list are not permitted.

    • The Journal regards requesting changes to an individual's name or information without their explicit consent as a breach of publishing ethics.

  3. The copyright for articles published by the Journal follows the regulations outlined in the Vietnam Intellectual Property Law 2022, the Law on Amending and Supplementing a Number of Articles of the Law on Intellectual Property.

    The author maintains complete copyright of their articles, encompassing both moral and property rights, as stipulated by the Vietnam Intellectual Property Law, for the manuscript submitted to the Journal. Specifically:

    • Moral right: the author possesses the right to determine the article's name or grant the Journal authority for naming, aligning with the Journal's regulations; the author holds the prerogative to either self-publish the manuscript or authorize the Journal for its publication; the author is endowed with the integrity right, enabling them to safeguard the manuscript against distortion, modification, or mutilation by others, this provision serves to protect the author's honor and reputation associated with the work; the author permits reviewers and editors of the Journal to suggest amendments and supplements for improving the manuscript's quality. This collaborative process is conducted in accordance with the Journal's regulations, ensuring continual enhancement and adherence to established standards.

    • Property right: held by the author, extend to the original manuscript submitted to the Journal. The author retains exclusive copyright of the intellectual property inherent in the submitted work. Furthermore, the author is entitled to submit a manuscript derived from their own published article. However, this derivative manuscript should differ in title, objectives, research results, and not exceed a similarity threshold of 30%. Additionally, the author possesses the right to submit the manuscript to another journal in the event of the Journal's refusal to accept or publish the work.

  4. Contributorship 

    The Journal mandates that authors explicitly outline who has contributed what to the planning, conduct and reporting of the work described in the article in the acknowledgments statement. An acknowledgments statement should include author contributors, non author contributors and group author contributors (collaborators). Contributors who have contributed materially to the paper but whose contributions do not justify authorship should be described clearly in the acknowledgments statement.

    Authors must determine among themselves the precise nature of each person’s contribution, and the Journal encourages open discussion among all participants (including author, co-authors, contributors) to reach a consensus.

    This is also the appropriate place to include contributions by patients or members of the public who have assisted as research volunteers, giving their names and specific roles. We encourage authors to fully acknowledge the contribution of patients and the public to their research where appropriate.

    Authors are requested to acknowledge the individual or organization providing financial support for the research execution or article preparation, elucidating the sponsor's role in the Acknowledge section. It is imperative to transparently disclose any financial support involved in the research or manuscript preparation, encompassing costs for research support (such as salaries, equipment, supplies, and miscellaneous expenses), human resources and employment, commitment to remuneration, patent or patent applications, grants, and other funding sources. Additionally, non-financial support may manifest through personal or professional relationships with entities or individuals. Authors must explicitly mention the names of organizations and individuals contributing to the research, including their role in shaping the manuscript's content and structure (ideas, design, data collection, analysis, standards, etc.).

  5. AI use 

    The Journal promotes the integration of artificial intelligence (AI) as a supportive tool in the research process. AI holds significant potential in analyzing extensive datasets, information retrieval, and the development of predictive models. The Journal emphasizes the exploration of principles and guidelines essential for maintaining transparency in AI utilization. The Journal encourages authors to furnish comprehensive information on the specific AI technology employed, rationale behind its selection, and the methodology applied. Additionally, the Journal encourages authors to assess AI results critically, contributing to the establishment of a robust foundation for future AI research and applications.

    To ensure transparency in reporting on the use of artificial intelligence (AI), authors must incorporate explicit details about the use of AI in the "Acknowledgments" section of the manuscript. This information must encompass the type of AI technology employed, the rationale for choosing AI, and the specific role of AI in the research process. In instances where AI is integral to the research, a comprehensive description must be provided in the "Methods" section. It is important to note that the editor reserves the right to request additional information or make necessary adjustments to content in order to enhance transparency and align with publication standards. This ensures that the reporting of AI usage in the manuscript is thorough, clear, and in compliance with editorial guidelines.

1. Ethical Oversight

The Journal recognizes that ethical oversight, as defined by COPE, encompasses various aspects, including, but not limited to, policies related to consent for publishing research involving vulnerable populations, preventing harm or injury to animals and humans, safeguarding confidential data, and regulating marketing activities, accordingly:

  • Regarding the research related to chemicals, processes, and hazardous equipment, the authors are required to confirm that all experiments were performed following the procedures of Vietnamese Law, and/or the instructions of relevant international organizations, as well as the Regulations of Ho Chi Minh City Open University.

  • Regarding the research involving animals and human research participants, the authors must confirm that all experiments were performed following relevant guidelines and regulations. Research involving human research participants must have been performed according to the Declaration of Helsinki and the Regulations of Ho Chi Minh City Open University. If the study has been granted exemption from requiring ethics approval, details of the committee granting exception should be included in the manuscript. Manuscripts must also include a statement affirming that informed consent was obtained from all human research participants. Privacy rights, personal confidentiality (personal information, photos, medical records, etc.) need to be protected. If identifiable images from human research participants are used, the authors must include a statement in the published articles affirming that they have obtained informed consent for publication of those images.

2. Conflict of intellectual property

Both authors and readers who identify violations of ethical and intellectual property standards, conflicts of interest, discrepancies related to author contributions, or contraventions of other Journal policies are encouraged to formally notify the Journal in writing, providing evidence of the alleged violation. In line with Ho Chi Minh City Open University's mission to advance scientific research, the Journal is committed to promoting and adhering to the highest standards of research ethics, guided by the Committee on Publication Ethics Core Principles (COPE's Core Practices).

Research misconduct encompasses a range of activities, including but not limited to: 

  • Fabrication: The act of making up data or results, observations, or characterizations that never occurred in the gathering of data or running of experiments.

  • Falsification: The act of manipulating research materials, equipment, or processes, or changing or omitting data or results such that the research is not accurately represented in the research record.

  • Plagiarism: The act of intentional or unintentional use of other scholar works (text, results, data, figures, images, ideas, etc.) without appropriate attribution, citation, or acknowledgment. Plagiarism is a serious concern in scientific ethical standards, could be in many forms including, but not limited to unacknowledged copying the work of others (individuals, corporations, non-governmental organizations, etc.); copying a large amount of other people’s works (even though sources are correctly cited); providing inaccurate information about the author and the source of information; re-writing other people's works in personal writing; reusing substantial parts of the author’s published work without providing the appropriate references, or using more than 30% of articles published previously by the author, is called duplication (including publishing a manuscript in several journals, and/or adding a small part into a previous work to generate new research).

All manuscripts will be checked for plagiarism and research duplication by Turnitin software, helping to identify the source that has been copied. The Journal complies with the regulations on plagiarism of academic products issued by Ho Chi Minh City Open University.

The Regulation on Duplicity: Academic works that verbatim reproduce a passage containing 20 words or more or have an overlap of 25% or more and each source exceeds 2%, or only change the title or data while keeping the same content is considered a violation.

3. Academic Integrity and Ethic Detection

Academic Integrity is a fundamental concept in research, encompassing adherence to ethical principles and standards throughout the research process. It involves recognizing and upholding ethical regulations and principles in all research-related activities.

To enhance the quality, integrity, and significance of scientific articles, the Journal has established the following process for ethics and academic integrity detection: 

  • Editorial screening: During this stage, the editor reviews the submitted manuscripts to assess its compatibility with the Journal's scope and adherence to academic ethical standards as outlined in the Journal's guidelines. Editorial screening takes into account various aspects of the article, including its content, research methodology, and writing style. If any violations or discrepancies are identified, the Editor reserves the right to reject the article and will provide the author with a clear explanation for the rejection, along with supporting evidence.

  • Plagiarism checking in editorial screening: Editors employ the Turnitin tool to conduct a plagiarism check on all manuscripts submitted to the Journal. This step is crucial to ensure the highest level of academic integrity in the author's work. Addressing any instances of plagiarism or duplicate content is mandatory. The Editor will communicate the results of the plagiarism check to the author. The overlap rate complies with the Journal's regulations as outlined in Article 3, Clause 2 of this policy. Furthermore, the manuscript should not include verbatim reproduction of a paragraph that consists of 20 words or more. This rigorous process ensures that the submitted work complies with the Journal's standards for originality and academic integrity.

  • Review: The Journal employs a double-blind review process, wherein both the authors' and reviewers' identities remain confidential. This approach is adopted to eliminate bias and ensure fairness throughout the article review process. By keeping the identities anonymous, the peer-review process guarantees that the assessment is solely based on the quality and content of the paper, devoid of any personal acquaintances or influences. Throughout this stage, the reviewers focus on evaluating the scientific validity, quality, and reliability of the article to ensure it meets the requisite standards for publication. Reviewers engage in a comprehensive examination of the article, assessing its content, research methodologies, logical consistency, results, conclusions, as well as its academic significance. They provide constructive feedback and suggestions to the author, highlighting both the strengths and weaknesses of the work and proposing improvements that can enhance the overall quality of the paper. The Editor subsequently communicates the review results to the author and requests adjustments to the article based on the editors’ and reviewers' recommendations.

  • Plagiarism checking before approval: This is a highly crucial step in the article preparation process to ensure the uniqueness, quality, and adherence to standards before publishing. This process is vital in upholding ethical and academic standards and preventing any infringement on the intellectual property rights of others. The overlap rate complies with the Journal's regulations as outlined in Article 3, Clause 2 of this policy. Furthermore, the manuscript should not include verbatim reproduction of a paragraph that consists of 20 words or more.

  • Post-Publication Discussion: The Journal actively encourages readers, particularly researchers, to engage in discussions about published articles. Readers can send their comments and suggestions to the Editor via email at journalofscience@ou.edu.vn.

4. Handling allegations of research misconduct 

Allegations of research misconduct should be made under the following considerations: 

  • Significant departure from ethical principles: The alleged wrongdoing should involve a substantial departure from established ethical principles, such as fabrication, falsification, or plagiarism. Minor or unintentional errors should be addressed differently.

  • Intentional misconduct: Misconduct should be demonstrated to be intentional, indicating a purposeful violation of ethical standards rather than inadvertent errors.

  • Specific and clear evidence: The allegation should be supported by specific and clear evidence that substantiates the claim of misconduct.
