For good journal governance and quality assurance, all authors must follow the manuscript flow according to journal policy, including submitting, reviewing, revising, editor's decision to accept or reject, APC payment, issuance of LoA, editing/layout, publish. The journal policy does not accept APC payments and early distribution of LoAs. For further information, you can contact the Jayapangus Press admin at a number that will be emailed after submitting the manuscript. Thank You.
