    Background: By investigating accidents in industries, it can be concluded that a significant proportion of work-related accidents occur in the construction industry. The present study aimed to apply a hybrid model in identifying and prioritizing risks in a construction project with new machinery. Methods: In this study, the methodological shortcomings of the traditional failure mode and effects analysis (FMEA) method and the need to prioritize control measures were modified by the analytical hierarchy of process (AHP). The FMEA was used for risk identification and risk assessment in the elevated highway construction project, then AHP accidents were prioritized according to their physical, psychological, economic, and socio-political burden. Results: In the AHP structure, several sub-criteria for each criterion were considered and weighted for each item. The five activities included crane collapse, falling from a height, collapse, and electrocution devices that their risk priority number is more than 250 weighted by the AHP. Discussion: Based on the literature, the traditional FMEA has many shortcomings that need to be corrected by other methods. This study aimed to modify the traditional FMEA method using a hybrid model. Conclusion: The findings of this study showed that in urban projects, hazards threaten workers, citizens, and company properties. In addition to accidents, deaths, and injuries, they have negative consequences, such as health, psychological, economic, and socio-political impacts. Accidents cause loss of human life, worker's mental health problems, damage to equipment or property, worker's productivity loss, and affect the profit and reputation of the organization. Due to many deficiencies of the conventional risk priority number (RPN) in the FMEA method, it was criticized, and to enhance the performance of the FMEA in risk analysis, various risk priority models have been proposed

    Abstract Background Climate change has been identified as the greatest threat to global health in the twenty-first century, with its unfavorable health consequences being among its impacts on humans. Exploring the perspectives and understanding of healthcare professionals and service providers concerning climate change becomes imperative. The aim of this study is to investigate the perceptions and understanding of final-year medical students regarding the health impacts of climate change on individuals and the healthcare system using a qualitative content analysis. Methods This study employed a qualitative content analysis approach. Face-to-face interviews were conducted with the aid of an interview guide to explore the students' awareness, understanding, and attitudes towards the impacts of climate change on public health and the healthcare system. The collected interview data were subsequently organized into codes, categories, and subcategories based on the students' perspectives and attitudes towards climate change. Results Fifteen medical intern students were interviewed for this study, and the qualitative findings were categorized into 3 categories, 23 subcategories, and 229 codes. The study's findings revealed various health impacts of climate change, which were classified into three main categories, including environmental effects with 8 subcategories, socio-economic effects with 8 subcategories, and health effects with 7 subcategories. The study's findings revealed medical students' perceptions of various health impacts of climate change and These findings suggest that medical student understand that climate change has significant impacts on individuals' health and society, mainly through environmental degradation, increased risks, and climate-related disasters, which ultimately lead to adverse health outcomes. Conclusions The perspectives of medical students in this study indicate that climate change may not have a direct and immediate impact on the health of individuals and communities. However, it can significantly influence their health and socio-economic well-being by exacerbating or causing environmental problems, increasing the risk of weather-related events and natural disasters, ultimately leading to adverse health outcomes. While the medical students' perspectives on the health impacts of climate change are indeed broad, incorporating scientific knowledge about this topic into the medical curriculum and educating students on how to deal with patients affected by these consequences can have a significant impact on health management. This proactive approach, despite the students' already comprehensive understanding, can enhance their preparedness to address the health effects of climate change and contribute to strengthening the healthcare system's resilience in the face of climate-related challenges
