Note: 

1. (Free*) The journal does not charge Article Processing Fees and will publish high-quality manuscripts accepted in 2025 free of charge.
2. Please note that an additional fee will be charged if the submitted article requires English language editing and proofreading. This applies if our editorial team identifies the need during initial checks, or if a peer reviewer recommends language improvement as a condition for publication. The fee will be communicated in advance, and editing will proceed only after the author’s confirmation. This ensures clarity, accuracy, and publication quality.

2. Article Processing Fee After Acceptance
   The article processing fee is payable only after acceptance of the manuscript for publication.

3. Non-Refundable Processing Fee
   Once the article processing fee has been received and the publication process has begun, it is non-refundable.

4. Overpayment Refunds
   In the event of an overpayment, we will refund the excess amount within 30 business days after identification or upon receiving valid proof of the overpayment.
