objective: to determine the epidemiology and pattern of emergency operating room workload in nemazee hospital affiliated with shiraz university of medical sciences, shiraz, iran. methods: all surgical emergency operations which were performed in nemazee hospital, shiraz, iran were collected over twelve months (september 2007 to september 2008). the data obtained included indications, presenting...

background and objectives: operating room (or) scheduling is key to optimal operating room productivity. the significant uncertainty associated with surgery duration renders scheduling of surgical operation a challenging task. this paper proposes a novel computational stochastic model to optimize scheduling of surgeries with uncertain durations. the model considers various surgical operation co...

pullback test has no scrupulous theoretical establishment. it is based on the hypothesis that the response ofthe structure can be related to the response of an equivalent single degree-of-freedom (sdof) system. this implies thatthe response is controlled by a single mode. in fact, the steel frame of each safe room, which is introduced within theunreinforced masonry buildings for protecting the ...

introduction: the research results showed that there was a relatively large gap in training operating room skills and clinical practice, so that clinical training did not enable students to perform the required tasks. one of the new approaches in training is a mentoring program. the aim of this study was to review mentoring of operating room students. methods: this study was a systematic review...

phenolic resin is among the oldest thermoset resins that have found wide spread applications in several industries, largely due to its high thermal resistance. in this research, room temperature curing of phenolic resin and its reinforced silica composite has been investigated by p-toluene sulphonic acid as a catalyst. mechanical properties of the composites such as impact strength, flexural pr...

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...
