Introduction: Considering the importance of identifying and tracing primary sources of Covid-19 crisis in infection control, this study was carried out with the aim of identifying the occupational tasks effective in transmitting Covid-19 in the event of death of a female staff in medical record unit in Shafa Takestan Hospital (Qazvin Province). Material and Methods: This case study was perform...
Around 75% of civilians have experienced at least one traumatic event in their lives, and this number is considerably higher in many parts of the world, as well as in military veterans and first responders. Of those exposed to trauma, 15-25% will develop Posttraumatic Stress Disorder (PTSD). PTSD extracts enormous economic, health, and quality of life cost. Thus, it is critical to underst...
The paper analyzed the system requirements for online shopping in general and specific requirements for event ticket online selling systems. The paper discussed the critical design and implementation issues for Electronic Event Ticketing System and prospective issues for fully automated Electronic Event Ticketing with high availability. The research is based on the real medium size Event Ticket...
recent studies in scientific education as well as foreign and second language instruction suggest that thinking has rarely been an integral part of education and training in classroom. some scholars decried the lack of emphasis on thinking in the institutes and schools. they noted that memorization and drills were rewarded,while inquiry, reflection, and consideration of alternatives were frowne...
background: carbon monoxide (co) poisoning has remained a common, serious and often unrecognized event and constitutes a public health problem in morocco. the objective of this study is to describe the epidemiological and clinical profile and risk factors of co poisoning in the region of fez-boulemane, morocco. methods: this is a retrospective study on co poisoning cases occurred in the region ...
this paper measures event risk which is introducing by the ball committee to measure the effect of sudden news. this study calculates event risk by using the data of registered firms in tehran stock market between 1993 and 1994. for computing event risk, we use daily market capitalization for 80 firms during 1993-2009, then dividing these firms to three baskets; big, medium and small. the model...

A proposal is made for the development of a feature-oriented reuse capability for safety-critical software construction using rigorous methods. We précis the Event-B language the evolution of the B-Method of J.-R. Abrial [1] a leading formal method for safety-critical software development. Current and new infrastructure for scalable development with Event-B is outlined, and contrasted with supp...
In event-driven sensor networks, when a critical event occurs, sensors should transmit quickly and securely messages back to base station. We choose Elliptic Curve Cryptography to secure the network since it offers faster computation and good security using shorter keys than RSA protocol. In order to minimize the computation time, we propose to distribute the computation of scalar multiplicatio...
