The five different microwave power levels (800, 640, 480, 320, and 160 W) assisted with the vacuum of 40 kPa were investigated for the drying kinetics, effective moisture diffusivity and rehydration ratio of the dried pomelo albedo. The comparison of some product quality indicators after production and 6 months of storage was also taken place in this study. The higher microwave power levels provided the shorter drying times, the higher moisture diffusion and the drying rates. Drying time at 160 W needed more than 120 min while the rest needed less than 25 min to reach the moisture content below 8% (dry basis). By basing on χ 2 and root mean square error and R 2 , experimental drying data were best performed for the Page equations compared to other eight models (Diffusion approach, Two term exp, Henderson and Pabis, Lewis, Logarithmic, Vermar, Two modified compartment, Wang and Singh).The effective moisture diffusivity coefficient determined by Fick's second law was varied from 1.0 Â 10 À5 to 6.52 Â 10 À7 m 2 /s. The developed models describing the relationship between different drying parameters in this study can be used for optimizing the parameters in the drying process at a larger scale. The microwave power level of 480 or 640 W and the sample weight of 50 g were recommended for the drying of the pomelo albedo. Under these conditions, the dried albedo product possesses high quality. Most of the characteristic quality indicators changed insignificantly as compared after production and stored for 6 months at room temperature (25-28 C).

Background: The culture of the school is one of the most significant factors to consider when trying to create an efficient learning and working environment for the staff, teachers, and students at the schools. Aim: The purpose of the research was explained to the behavior of students with regard to school culture in high schools. Methods: The study was conducted in Hue, Vietnam, from 2021 to 2022, and it sampled two high schools with a total of 339 students and 55 teachers. Results:  The research questionnaire was prepared by teachers and students at the high school level, and it was based on the behavioral manifestations of high school students. According to the instructors and other students, the students have a sense of cultural conduct. This includes respecting adults, including their parents, teachers, and other school officials, as well as dressing in a manner that is acceptable for their age and the situation. Nonetheless, there are still some children who do not dress well, who are not appropriate for the situation, who behave inappropriately toward teachers and other school officials, and who are likely to pick up risky behaviors such as smoking, gambling, and other such activities. Conclusion and Implications: The findings of this study on the behaviors and cultural expressions of high school students have made it possible for educators and teachers to design curriculum that is suitable for their students.   Received: 17 April 2023 / Accepted: 20 June 2023 / Published: 5 July 2023

E-learning has gained popularity as a method of delivering education recently and offers many advantages to enhance the learning experience for students. Technology allows teachers to design more interactive and engaging lessons that cater to different learning styles. It can also provide opportunities for teachers to incorporate virtual simulations and real-time data which can help students better understand complex concepts. The total number of survey samples was 187 teachers. Awareness of the need and purpose of applying information literacy in the organization of teaching activities was created to analyze. The results of the findings were interpreted in three ways: (i) Self-assessment of teachers’ competence in applying technology in organizing teaching activities.  (ii) Awareness of the necessity of using online applications in organizing teaching activities in schools.  (iii) Awareness of the goal of using online applications in the organization of teaching activities. Based on the results of the current study, the article establishes the process of applying online applications in the organization of teaching activities and proposes recommendations for subjects directly related to the application of online applications. High school administrators, teachers and educational management agencies at all levels are using online innovation to organize teaching activities in high schools.
