In this group article, part of the teaching of advanced dynamics course has been done in the form of group-based training projects. In this project, the mechanism of a spinning ride is designed and then engineering analyzes are performed on it. The system of this spinning ride must be designed in such a way that the absolute acceleration of the human head is equal to six times the acceleration of gravity. The most basic thing to do is conceptual design. Engineering analyzes such as dynamic analysis and motion simulation; finite element analysis is also performed to obtain natural frequencies and to determine the deformations caused by loading. After completing the above steps, information will be provided about materials and manufacturing processes. Due to the fact that this project was carried out in the form of a new method of learning advanced dynamics in the form of nine groups at Sharif University of Technology and the groups competed with each other, in the end, students were surveyed about the amount of learning from this method of teaching. [ABSTRACT FROM AUTHOR]

Background: Diseases and disorders related to mental health are spreading like other chronic diseases all around the world. Considering the role of food in the prevention and treatment of these disorders, including major depression, investigating the relationship between different food patterns and this disorder is of particular importance. The aim of this study was to compare Dutch healthy eating and healthy eating indexes and anthropometry in patients with major depression with healthy individuals., Methods: In this case-control study, the final analysis was performed on 67 men and 111 women with an age range of 20-30 years. Height (cm), weight (kg), food frequency questionnaire (FFQ), physical activity (MET-min/week), demographic and PHQ-9 questionnaires were taken from all participants. In the following, all the food ingredients and their components were extracted and used to calculate HEI-2015 and DHD. Statistical analysis was performed using SPSS software with independent t -test, logistic regression and chi-square., Results: It was found that people with major depression in this study were mostly women and occupied. The average HEI-2015 in healthy people and those with major depression was 58 and 54.3, respectively. Also, the average DHD in these people was 60.5 and 55, respectively. HEI-2015 and DHD had a significant negative correlation with depression score ( r = -0.16, p -value = 0.03) ( r = -0.19, p -value = 0.01). Also, in the logistic regression model, before and even after adjusting confounders, HEI-2015 and DHD had a reduced odds ratio in people suffering from major depression. The two groups did not differ significantly in terms of the average factors of height, weight and body mass index (BMI)., Conclusion: It seems that HEI2015 and DHD have a significant relationship in reducing major depression. However, due to the small number of studies in this regard, especially in the field of DHD, the need for more studies seems necessary., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Tohidi Nafe, Movahedi and Djazayery.)
