Dear Colleagues,

It is recognized that engineering and technology are important tools in Thailand 4.0. Today, technology is moving very fast which makes the theory and truthful information in the textbooks does not often provide useful information for learning and use for citation. For this situation, we formally launched the International Scientific Journal of Engineering and Technology (ISJET) and proceed to issue quality articles through rigorous and quick review processing schemes. This year, the ISJET is indexed in the Thai Journal Citation Index (TCI) which can assure our journal quality.

As we forward-thinking, move ahead and build on our success, we would appreciate feedback from you, the readers of and contributors to the ISJET. Hence, you are encouraged to contact the Editors or the journal coordinator on any aspect of the journal. Your input is, as always, highly valued as it helps us improve further the quality of our offering. Finally, on behalf of the Editorial Board, I would like to take this opportunity to thank everyone who has contributed to ISJET in various capacities, and to urge you to continue submitting your valuable research to publish in the journal. Your cooperation will be highly appreciated. If you have any questions or suggestions, please directly email me or the journal coordinator. I look forward to hearing from you.

With kind regards,
Assoc. Prof. Dr. Parinya Sanguansat
Editor-in-chief
