JUSTE (Journal of Science and Technology) presents articles on science and technology. The main theme of JUSTE is technology engineering for the convenience of human life. Therefore, we will present manuscripts in the fields of engineering, biology, environment, mathematical models, computers, and the development of advanced materials in each volume. Apart from these scopes, it is still possible to receive articles in science and technology if they fit the main theme. JUSTE is published twice a year in April and October. We will also present article manuscripts according to the sub-themes determined by the editorial team for each volume and issue number.
