JUSTE (Journal of Science and Technology) presents articles on science and technology. The central theme of JUSTE is technology engineering for the convenience of human life. Therefore, we will present manuscripts in 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.
