background: stress is a nonspecific reaction to everything the body needs. although occupational stress exists in every occupation, it is seen with more frequency and intensity amongst those occupations related to human health. in this study, we aimed to investigate the level of occupational stress in operating room staffs working in the hospitals affiliated to isfahan university of medical sci...

results higher levels of stress were due to the fear of being infected by hiv and hepatitis patients with mean of 3.2 and 58%; and lack of weekends with mean of 3 and 44%. the lowest levels of stress were related to inadequate skills with mean of 2.18 and 32%, and environment light with mean of 2.14 and 34.7%. stress was significantly related to job status, conflict of doctors and nurses as wel...

concurrency control is one of the important problems in operation systems. various studies have been reported to present different algorithms to address this problem, although a few attempts have been made to represent an overall view of the characteristics of these algorithms and comparison of their capabilities to each other. this paper presents a survey of the current methods for controlling...

chemical vapor deposition (cvd) is one of the most popular methods for producing carbon nanotubes (cnts). the growth rate of cnts based on cvd technique is investigated by using a numerical model based on finite volume method. inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal cvd reactor at atmospheric pressure. in thi...

hypothermia generates potentially severe complications in operating or recovery room. forced air warmer is effective to maintain body temperature. extremely low frequency electromagnetic field (elf-emf) is harmful to human body and mainly produced by electronic equipment including convective air warming system. we investigated elf-emf from convective air warming device on various temperature se...

background and purpose: the objective of medical education is to train competent and qualified workforce in order to provide services in various health environments. one of the important objectives of operating room students is to train workforce who can involve in patient’s health and recovery. training these students should cause clinical ability and independent decision making during surgery...

background and purpose: upon centuries, wars have taken over countries due to theadvancement of sophisticated warfare,causingserious injuries among soldiers. nurses are directly involved in preoperative and postsurgical patient care. one of the most remarkable contributions of the iranian operating room nurses was to provide medical care for wounded soldiers in field hospitals during the iran-i...

conclusions the world health organization (who) has suggested relatively relaxed limits of 100 cfu/m3 for bacteria and 50 cfu/m3 for fungi in the hospital air. therefore, quantitative and qualitative outcomes of this study demonstrate that contamination level and bacterial variety in surgery rooms and emergency departments is high and effective measures must be taken to control the possible hea...
