Referring to the increasing quality of our indexing, we hereby announce that the APC (publication fee) will be raised to USD 200 starting from Volume 16 No. 2. Manuscripts that have been accepted and are included in the next issue will be subjected to a new APC regulation. We notify authors well in advance so that authors are aware of this new regulation and can prepare well.

Thank you.
