Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

The dynamic load resistance of the Darrieus type wind turbine to changeable wind speed is investigated in this study, and the value of the force received by the wind turbine blades is calculated. Using Autodesk Inventor Professional 2019 software, the analysis was done quantitatively. The Darrieus turbine was tested at 2.5 m/s with a force value of 0.195 N, 3.5 m/s with a force value of 0.274 N, 4.5 m/s with a force value of 0.352 N, and 5.5 m/s with a force rating of 0.430 N. From the simulation results using the Autodesk Inventor Pro 2019 software, the effect of gravitational force is greater than the wind force in, so stress analysis is mainly caused by gravity while the wind force has no significant impact. The simulation results also have a characteristic that the higher the wind speed, the lower the stress value. In addition to the dynamic load simulation, the author also tries to implement the Darrieus wind turbines. The wind turbine blade rotation will be faster, and the Wind Generator will produce a greater voltage if it is supported by sufficient wind speed.
This paper presents a study on the English-majored students’ interests in the standard American accent while studying at university and the difficulty they might have in understanding American accents in listening comprehension tasks in particular and in real-life situations in general. The study also addressed the same problem in order to help a group of school teachers to improve their level of English. The findings reveal that most of the students and teachers surveyed have been mainly exposed to the standard British English accent and that’s why they somehow have difficulty in understanding the standard American accent which is quite different. It is suggested that the standard American accent should be taken into account more seriously, especially at schools and universities. As a result, it is expected that those institutions should try to raise English learners’ awareness in the difference among English accents and gradually improve their listening skills.
