In the present study high-school pupils’, and adult students’ opinions were evaluated through a modern structured MOODLE interactive course, designed for the needs of the laboratory course “Automotive Systems”. The study concerns Greek secondary vocational education pupils aged 18 and vocational training adult students aged 20 to 50 years. The multistage, equal size simple random cluster sample was used as a sampling method. Pupils and adult students of each cluster completed structured 10-question questionnaires both before and after attending the course. A total of 120 questionnaires were collected. In general, our findings disclosed that the majority of pupils and adult students had significantly improved their knowledge and skills from using MOODLE. They reported strengthening conventional teaching, using the new MOODLE technology. The satisfaction indices improved quite, with the differences in their mean values being statistically significant.展开更多

Control group received conventional hypoglycemic therapy, HIIT group received hypoglycemic combined with high-intensity interval training therapy, and the intervention lasted for 3 months. The differences in blood glucose control, adipocytokine secretion and oxidative stress response were compared between the two groups before and after intervention.Results: Before intervention, the differences in blood glucose index levels in peripheral blood as well as the contents of adipocytokines and oxidative stress indexes in serum were not statistically significant between the two groups of patients. After 3 months of intervention, blood glucose indexes FPG, FINS and 2hPBG levels in peripheral blood of HIIT group were lower than those of control group;adipocytokine APN content in serum was higher than that of control group whereas LEP, Resistin and CHEM contents were lower than those of control group;oxidative stress indexes MDA and ROS contents in serum were lower than those of control group whereas T-AOC content was higher than that of control group. Conclusion: Routine hypoglycemic therapy combined with high-intensity interval training can further control the blood glucose levels, regulate the secretion of adipocytokines and reduce the systemic oxidative stress response.展开更多
