From 2020 and henceforth, the assignement of Volumes and Issues of the journal will be changed, following the international standard. There will be one (01) Volume for each year, symbolized by the number “2”, meaning to the 2nd stage of the volume assignment. The last two digits are the number of the journal’s age. The Issue numbers of each Volume will be assigned in ascending numerical order, starting from 01. Special issues in English are given priority to be published as soon as possible.

Since the first issue was published in 1996, the year 2020 will be the 25th publishing year of the journal. Hence, the volume of the journal in 2020 will be "Volume 225".
