Envelopment analysis for global response to novel 2019 Coronavirus-SARS-COV-2 (COVID-19)
Communities are constantly seeking to manage the damages which are caused by crises. In this regard, health centers have become the most expensive unit of the health system as they provide quick and timely health care services to reduce the effects of unexpected accidents. So, their planning and preparation should be considered as an important part of strategic health policies. The purpose of t...
متن کاملCHALLENGES OF LABORATORY SAMPLING AND DIAGNOSIS OF SARS-COV-2 VIRUS OF DISEASE (COVID-19)
Background & Aims: Given the prevalence of SARS-CoV-2 worldwide, it is essential to identify people infected with the virus and determine its different types to control the global outbreak of COVID-19. The results of the studies are controversial, so this study examines these diagnostic challenges, including the types of diagnostic methods, the type and time of sampling, and even the clinical c...
متن کاملA review of coronaviruses focusing on SARS-CoV-2 (2019-nCoV) the cause of COVID-19
Coronaviruses, enveloped positive single-stranded RNA viruses, have become significant pathogens for humans and other vertebrates since the outbreak of SARS (severe acute respiratory syndrome) in 2002 in China. These viruses could infect the respiratory tract of humans and other animals. The outbreaks of SARS and MERS (Middle East respiratory syndrome), which Bats are thought to be the origin o...
متن کاملAnalysis of inadequate cervical smears using Shewhart control charts
BACKGROUND Inadequate cervical smears cannot be analysed, can cause distress to women, are a financial burden to the NHS and may lead to further unnecessary procedures being undertaken. Furthermore, the proportion of inadequate smears is known to vary widely amongst providers. This study investigates this variation using Shewhart's theory of variation and control charts, and suggests strategies...
متن کاملEstimation in Shewhart control charts
The influence of the estimation of parameters in Shewhart control charts is investigated. It is shown by simulation and asymptotics that (very) large sample sizes are needed to accurately determine control charts if estimators are plugged in. Correction terms are developed to get accurate control limits for common sample sizes in the in-control situation. Simulation and theory show that the new...
