2. Research and Publication Ethics

Clinical Ultrasound follows the research and publication ethics guidelines set forth in the Ethics Guidelines of the Korean Association of Clinical Ultrasound, the Publication Ethics Guidelines for Biomedical Journals (http://kamje.or.kr/publishing_ethics.html), and the Guidelines on Good Publication Practice (https://publicationethics.org/files/u7141/1999pdf13.pdf) of the Committee on Publication Ethics (COPE).

1) Registration of Clinical Trials
A clinical trial or study should be registered with a national clinical trial registry (http://ncrc.cdc.go.kr) or an agency certified by WHO or the International Committee of Medical Journal Editors.

2) Disclosure of Conflicts of Interest
The corresponding author should disclose all information on conflicts of interest that may affect interpretation of the findings, including any financial support from or affiliation with a pharmaceutical company, any political pressure from an interest group, or any academically related issue, to the editors. In particular, any and all financial support used for the research should be clearly disclosed.

3) Written Informed Consent
Copies of written Informed consent from patients and approval from the institutional review board should be retained. As required, an editor or a reviewer may request a copy of written consent or approval to resolve related issues.

4) Requirements Regarding Human and Animal Rights
A study on humans should be consistent with the ethical standards set forth in the Declaration of Helsinki 1975 (revised in 2004). A study on animals including mammals or aves should be approved by the animal experiment ethics committee of the relevant institution, and conducted in accordance with Article 13 of the Animal Protection Act of the Republic of Korea or laboratory regulations equivalent thereto. An experiment plan approved by an animal experimental ethics committee should be available if required and requested by an editor or a reviewer.

5) Author Qualifications
A person listed as an author in a manuscript should satisfy the following requirements: 1) contribution to the basic concepts and design of the study, and analysis and interpretation of the data; 2) significant contribution to writing, revising key parts of, or improving on the manuscript; and consent to the content of the final manuscript. In the event that the number of authors exceeds six, descriptions of the roles of the respective authors should be provided when submitting the manuscript.

6) Originality and Duplicate Publication
A submitted manuscript should be original and may not be considered for simultaneous publication in any other journal. No part of a manuscript may be duplicated in any other journal without permission from the Editorial Committee once its publication is finalized. In the event that a manuscript published on Clinical Ultrasound is confirmed to be duplicated in another journal, that fact will be published in the journal, any institution the authors are affiliated with will be notified, and the author will be subject to a penalty.

7) Secondary Publication
A manuscript may be republished as long as it satisfies the republication requirements set forth in the Uniform Requirements for Manuscripts Submitted to Biomedical Journals.

8) Copyright Permission
When citing any figure or table from a published article, copyright permission must be obtained from the journal of publication, and a reference to the copyright permission should be included in the manuscript.

3. 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 conf licts 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 follow the flowchart provided by the COPE (Committee on Publication Ethics; http://publicationethics.org/resources/flowcharts). The Editorial Board of Clinical Ultrasound will discuss the suspected cases and reach a decision. Clinical Ultrasound will not hesitate to publish errata, corrigenda, clarifications, retractions, and apologies when needed.

4. Review Process

All received manuscripts are reviewed for publication based on research quality, originality, and clinical and scientific significance. In general, a preliminary decision on publication is made within four weeks from receipt, and the reviewers’ opinions are provided using the corresponding author’s email address. A revised manuscript should be resubmitted by the corresponding author online, along with a description of how the manuscript was revised in accordance with the reviewers’ comments. A manuscript should be reviewed by at least two experts, and a reviewer may demand a second or a third review. In the event that a revised manuscript is not submitted within eight weeks from the Editorial Committee’s decision on publication, the manuscript is deemed to have been withdrawn.

5. Copyright

Once the journal decides to publish a manuscript, the KACU reserves the copyright on the manuscript, and the manuscript may not be published in another journal without written permission. A copyright release form should be prepared and submitted to the office of the Editorial Committee by fax or mail upon approval of publication.

6. Online Submission Rules

All manuscripts should be submitted to Clinical Ultrasound by logging in at the Clinical Ultrasound online submission website (http://submit.clinicalultrasound.org/) and following the instructions therein.
