All manuscripts must be submitted through the journal’s online submission system, which manages the entire peer review and publication process, from initial submission to final publication. Authors must first register and create an account before submitting their work. Once registered, they can upload manuscripts and supporting documents, track the progress of their submission, receive editorial decisions, and submit revisions when required. Existing users can login to access their accounts and continue the submission process. All submitted manuscripts must be original and unpublished work, and they should not be under review or consideration by any other journal at the same time. The corresponding author holds primary responsibility for the accuracy and integrity of the manuscript, manages all communication with the journal, and ensures that all listed co-authors meet the required authorship criteria. For any pre-submission queries or technical support, authors may contact the Editor-in-Chief at editor@spjmhs.com
