Asia-Pacific Journal of Science and Technology (APST)

The Asia-Pacific Journal of Science and Technology (APST), formerly known as the KKU Research Journal, is a peer-reviewed journal published by the Research and Technology Transfer Affairs Division of Khon Kaen University. The journal's title was changed in order to attract more international readers and authors.

The journal accepts English-language manuscripts of original research and review articles which have never been published elsewhere. The main focus of the journal is to publish work that leads to creative practical applications, environment preservation, and human well-being. Research areas covered by the journal include engineering science, technology, agricultural science, and health science. Manuscripts reporting on research that integrates any of the aforementioned fields are especially encouraged. Our core interest is in the use of engineering, scientific, and technological knowledge to assist, co-operate with, and enhance other fields, such as health and agricultural science, in order to improve human well-being. We particularly welcome research that integrates various fields, including plant science and pharmaceutical science or plant science, agricultural engineering, automatic control, and energy technology.

The journal employs a double-blind review process, in which authors and reviewers are anonymous to each other throughout the process.
