Authorship
The ICMJE recommends that authorship be based on the following 4 criteria (www.icjme.org):
1) Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
2) Drafting the work or revising it critically for important intellectual content; AND
3) Final approval of the version to be published; AND
4) Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.
Corresponding Author
There must be a corresponding author (not more than 2 in a manuscript) clearly indicated in the title page, with his/her full academic affiliation, contact information (email, tel., fax).
The corresponding author is the person who is taking the responsibilities of the manuscript being prepared following research and publishing integrity and ethics.
The galley proof will be sent to the corresponding author for proofreading. Meanwhile, the galley proof might be also “carbon copy, CC”to the submitting individual, but that is not for all articles.
“The corresponding author is the one individual who takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process, and typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and gathering conflict of interest forms and statements, are properly completed, although these duties may be delegated to one or more coauthors. The corresponding author should be available throughout the submission and peer review process to respond to editorial queries in a timely way, and should be available after publication to respond to critiques of the work and cooperate with any requests from the journal for data or additional information should questions about the paper arise after publication”( www.icjme.org).
Submitting Author
The submitting author is the person who carries out the submission work and submits the manuscript (usually via online submission portal) to the journal. The submitting author is not necessarily the corresponding author, however, upon receiving the manuscript submitted by the individual (submitting author) other than the corresponding author, we assume that the submitting author has obtained explicit permission from the corresponding author to do so, and we assume that the corresponding author is fully aware of and approves the submission and oversees the editorial procedures of the manuscript.
In this circumstance, a submission approval letter from the corresponding author might be requested by the editor, and the corresponding author should provide such letter before we do any processing of the manuscript.
Valid Email Address
The submitting author and corresponding author are responsible for providing valid and attended email address, and should check the email regularly, in order not to delay the editorial procedure.
The galley proof will be sent to the corresponding author for proofreading. Meanwhile, the galley proof might be also sent “carbon copy, CC” to the submitting individual, but that is not for all articles.
