Construction workers are considered one of the most vulnerable health group workers. Exertional heat illness (EHI) is a well-recognized health hazard that causes significant sickness and death. The purpose of this study was to assess construction workers' environment and hydration status and to evaluate the effect of health education program on workers. An interventional study was conducted on 89 construction workers in Port Said City. Assessments of workplace environment and workers' hydration status were done by using workplace evaluation checklist, wet-bulb globe temperature, urine specific gravity, and urine color chart. A pre-post-test design was used in the evaluation of workers' knowledge and behavior regarding EHI. A health education program was conducted to improve workers' knowledge and behavior; then, evaluation was done after 1 month. The most reported symptoms of heat illness were sweating (100.0%), dizziness (98.0%), and muscle pain (82.0%). Most workers showed signs of minimal dehydration (78.7%). There was a significant improvement in workers' knowledge about EHI and behavioral action for prevention after health education. Construction workers are at high risk of exposure to EHI which raised the attention to provide educational programs which can guide workers to follow healthy behaviors and prevent EHI.

Background: The realization of the profession's role in both of global and personal concept affected the self-identification among 2020 medical students. COVID-19 pandemic can hinder, accelerate, or change medical students' professional identity formation. Objective: To assess the level of satisfaction about blended learning among undergraduate medical students at Zagazig University and to determine challenges, which face the medical students during blended learning education in Faculty of Medicine. Patients and Methods: This cross-sectional study was performed during the period from September 2020 to July 2021 at Zagazig University, Egypt. This research included 277 undergraduate medical students. Results:The current study reported that interaction satisfaction score ranged from 18 to 53 with median 37 and 53.1% of students reported high satisfaction with interaction domain. There was statistically significant correlation between total satisfaction score and both age and technology barrier. There was statistically non-significant correlation between total satisfaction score and communication barrier. Conclusion: The results show that the majority of our sample students were highly satisfied with blended learning and reported low barriers to e-learning. Students still prefer face-to-face courses despite their satisfaction with their grades and performance in blended learning courses.

Background: Genuine injuries have been reported at schools. Given that schools might not have any trained healthcare providers, teachers will provide first aid to students. Objective(s): To assess knowledge and skills regarding first aid and disaster management among primary school teachers, and evaluate the effectiveness of first aid and disaster management training program on knowledge and skills of those teachers. Methods: Intervention study, in the form of a training program on 43 teachers from two primary schools in Zagazig district, was performed. Evaluation was done through comparing school teachers' first aid and disaster management knowledge and skills before and after intervention by the use of a questionnaire and an observational checklist. Results: The percent of teachers with satisfactory first aid knowledge increased from 7.0% to 46.5% while for satisfactory practice, the percent increased from 4.7% to 51.2% after intervention. For satisfactory disaster management knowledge, the percent increased from 9.3% to 58.1% while for satisfactory disaster management practice, the percent increased from 2.3% to 23.6% after intervention with a statistically significant difference. Conclusions: First-aid and disaster management training program is an effective tool for improving teachers' knowledge and practice. Recommendation: First aid and disaster management training program should be one of the preplacement and in service training programs for primary school teachers to protect the life of children.
