Based on the specific guidelines, here is a more precise summary of the content and length requirements for manuscripts:

Length: Manuscripts should be restricted to around 5000 to 10000 words, including all sections such as the abstract, main text, references, and any appendices.

Title and Author Information: The first page should include the title of the manuscript, the author's name, affiliations, and contact information.

Abstract: The abstract should be no more than 500 words and should provide a summary of the entire paper, not just the conclusions. It should also include a list of three to five keywords suitable for indexing and abstracting services.

Literature Citations: Citations should follow a uniform style throughout the manuscript, preferably the latest edition of the American Psychological Association (APA) style. Reference management software like Mendeley or EndNote can be used to manage citations.

Plagiarism Limit: The manuscript should not exceed a plagiarism limit of 15%, and each individual source should be less than 4%.
