Background and Objectives: The importance of inhaling the clean air becomes more visible today. In the open air, a number of pollutants are considered as standard pollutants, one of which is particulate matter. The aim of this study was to study the environmental aspects of suspended particles in Tehran Municipality 9th district.Method: In this research, firstly, by referring to the municipality of district 9 and receiving the region information, the activities of the indicator of the producer of suspended particles were identified. Potential damage caused by these activities was identified and given the probability of occurrence, the power of diagnosis and severity of impact on the environment are classified. Findings: 7 activities were identified and for each activity 17 environmental consequences were identified from the EFMEA method. Of the 17 identified risks, 4 risks include lung disease, cardiovascular disease, digestive diseases and skin diseases that have the highest severity and ranked first to fourth and accounted for 2 risk accidents and driving disorder Traffic signs have the least impact intensity and ranked 16th and 17th ranked TOPSIS. Based on the EFMEA technique, pulmonary diseases with 524 and heart disease with 423 numbers have the highest risk numbers and misdiagnosis of driving tips with 50 and driving accidents with a 52-point risk factor. Discussion and Conclusion: Regarding the risk assessment in this study, it was revealed that 2 risks of pulmonary disease and heart disease have the greatest impact on the general health of the people in the region and by reducing the environmental risks of the area by taking some control measures.

The current research studies and examines the resilience of financial technology businesses. Resilience is determining strategies that can prevent inefficiency and collapse of businesses, or in case of system inefficiency, return to the pre-failure state or better than that in the shortest possible time. In addition, in this research, a comprehensive model of resilience of financial technological businesses and its introduction to the studied society is presented. All the failure modes that cause the inefficiency of financial systems for technological businesses include 12 failure modes that have been identified through research literature and experts' opinions. The statistical population of this research are managers and experts in the field of financial technology business and related groups in Tehran. In the analysis, the FMEA technique is used to determine resilience strategies in financial technology businesses before failure and the new FAAO technique is used to determine resilience strategies of financial technology businesses after failure. Through the FAAO technique, 6 strategies were determined to make risk management more resilient to failure.

The petrochemical industry is one of the most important industries in the oil and gas sector because of the enormous volume of facilities and processes, which have unavoidable risks and risks. Different risk assessment methods are used to manage these risks, especially in Engineering Procurement Construction (EPC) projects. On the other hand, considering the number and variety of risks in Engineering Procurement Construction (EPC) projects, determining their weight and ranking is of particular importance. This research is applied in purpose and is conducted in the head office of one of the petrochemical companies and two groups consist of experts of contract education and contracting unit (project management contracts) to collect the selected information that answered the questionnaires. In this study, the identified risks were evaluated and rated using the failure modes and effects analysis (FMEA) technique, and the critical risks were weighted and ranked using Analytical Network Process (ANP) and superconducting software. According to the results of the study, contract estimation risks were the least important and engineering sector risks were the most important. The results also showed that the risks of logistics sector, risks in contract estimation (values and costs), financial sector risks and finally engineering (design) risks are more important respectively.
