Aro was created with a long-term visions of becoming accessible to all researchers in Kurdistan and beyond, and covering a wide range of scholarly disciplines in sciences. Aro aspires to become a channel for exchanging of scholarly research by establishing academic connections between scholars globally.

The warm responses from researchers, academics and professionals in the last four years have made us create a wider Editorial Board which serves the wider submitted scientific manuscripts. However, it is clear that having a dedicated and well-organized editorial board for the journal is only one side of the coin. The other is the ability to attract submissions of quality research and scholarly work. We are thankful to all of those who put their trust in Aro and presented their original research work for publication in Vol V, No 1 of the journal, as well as, our thanks are extended to the 12 peer-reviewers from the Universities worldwide for their efforts in reviewing and enabling this issue of Aro.
