The Journal of the Association of Researchers has published articles by students, researchers, lecturers and scholars for 30 years, Issue 2, April - June 2025. After the quality assessment of articles based on the TCI, round 5, Year 2025-2029, the Association of Researchers received TCI tier 2 and the assessment results were revised for 1 year to be re-evaluated in 2026. The Journal of the Association has therefore improved and developed the quality and process of considering articles, which will start to be more intensive and have higher standards than before. In many topics, there will be a detailed examination, such as the topic of literature review and concepts, which must be written in a summary description, not separated into layers. References must be made by combining all references and summarizing them. In addition, the referenced sources must be no more than 5 years old, except for the original concept or theory, which is allowed to use the old B.E. or A.D. year. There is also a check back to the source to see if the information is real or not. And many other measures will be used to make the journal higher quality.

May everyone be healthy during the chaotic situation in Thailand, which has caused low productivity in the agricultural, industrial and service sectors. In addition, the country has affected the quality of people, the quality of education, the quality of public services and public health services. Thai society is still highly unequal, causing division and problems in living. May everyone be mindful and try harder in their work to adapt and overcome various obstacles.
