It is my honor and pleasure to welcome all the reader to KMITL Science and Technology Journal (KMITL-STJ). As editor-in-chief, I would like to express my sincere thanks to all the researchers and authors who have submitted their good research works to be shared and their research result to be exchanged in the current issue of the journal. Of course, the success of the journal would not have been possible without the support and dedication of editorial board members and reviewers who really had spent much of their times in shaping up the manuscripts. To all of those involved I give my gratitude and sincere thanks for such tireless efforts. Started from the current issued, KMITL-STJ has turned its page format to A4. Authors may feel more comfortable in preparing the final manuscript, especially ones who are using Microsoft Word. In addition to its hardcopy version, the KMITL-STL is also accessible via its website https://stj.kmitl.ac.th. It also should be noted that from now on the submission system as well as reviewing systems are webbased. It provides a great deal of convenience, tracking and management. Please visit the journal website and you may find most the information you need. However, for the sake of these simplicities, many authors may find some delays in the journal process during the turning. We hope most steps will be put in place soon.
