Beginning in the mid-1980s, the phenomenon of capital flight from developing countries received considerable attention in the economics literature. Capital flight destroys the domestic macroeconomic environment and decreases transparency and accountability. It restricts financial resources when a country is looking for economic growth and development. The purpose of this article is to measure t...

Abstract Introduction:Excessive daytime sleepiness and other sleep disorders are receiving much attention as a cause of work accidents. Sleep disorders can disturb sleep and waking alertness. While the pilots and other flight crews suffer from sleep disorders, they will be unable to monitor airplane systems. This will reduce the safety of the flight. The aim of this study is assessment and ana...

the air transport industry is seeking to manage risks in air travels. its main objective is to detect abnormal behaviors in various flight conditions. the current methods have some limitations and are based on studying the risks and measuring the effective parameters. these parameters do not remove the dependency of a flight process on the time and human decisions. in this paper, we used an hmm...

Introduction: The pilot has a continuous flow of various activities that require navigation, attention, and navigation working memory. Fighter pilots are more vulnerable to cognitive impairment due to positive gravitational acceleration. This point indicates the importance of their cognitive assessments. Objective: This study aimed to evaluate visual-spatial cognitive function and attention in ...

conclusions: thus, identifying the hf patients before the flight and providing them proper education about the events that may occur during flight is necessary. results: hf patients are more prone to experience respiratory distress, anxiety, stress, cardiac decompensation, and venous thromboembolism (vte) during air travel. although stable hf patients can tolerate air travel, but those with acu...
