We would like to announce that from August 18th, 2021, the submitted manuscripts will be prescreened on ThaiJo system. Once the manuscripts pass through the prescreening process, they will be automatically registered on the Editorial Manager (EM) system. The authors will then receive a submission link to fill out the information in the EM system and the reviewing process is then taken into place. After the manuscripts are accepted, the papers will be transferred back to the ThaiJo system for Proofreading, Copyediting, and Production.
