This issue has been led by Prof.Dr.Karl from Vietnam who has more than 1,000 papers published in various international peer review journals. He has a total of 22,386 citations, H-index at 66, and I-10 index at 410. I would say that he is one of the highest profiles in the field of public health and psychology in the world. Thank you so much for your support, even a small paper but it really reflects the aim of the journal and I hope we will get your contribution in the next issue as well.
