Introduction: Today, the infectious wastes of hospitals are considered as a public health problem. Considering the huge amounts of hazardous wastes and the disadvantages of incinerators, we need to investigate the non-combustible devices involved in biochemical treatment. This study was carried out with the aim of evaluating the cost-effectiveness of infectious wastes devices. Materials and Me...

this paper using generalized roeger's model calculated the lerner index for iranian active industries in 4-digit isic codes during the period 1995-2007. the findings indicate that the lerner index has been between 8 to 16 percent in 38 industries among 131 ones. the index also in different industries shows that more than 50 percent of iranian industries have monopolistic power such that th...

Traditional cache replacement algorithms are not easily applicable to a dynamic and heterogeneous environment. Moreover, the frequently used hitratio and byte-hit ratio are not appropriate measures in grid applications, because non-uniformity of the resource object sizes and non-uniformity cost of cache misses in resource information traffic. In this paper, we propose a Least Frequently Cost ca...

Caching has been used for decades as an effective performance enhancing technique in computer systems, among others. However, the traditional cache replacement algorithms are not easily applicable to WWW applications. Moreover, the frequently used hit-ratio and byte-hit ratio are not appropriate measures in WWW applications, because non-uniformity of the object sizes and non-uniformity cost of ...

Recent information about osteoporosis treatments and their nonfracture side effects suggests the need for a new cost-effectiveness analysis. The authors estimate the cost effectiveness of screening women for osteoporosis at age 65 and treating those who screen positive with hormone replacement therapy (HRT), raloxifene, or alendronate. A Markov model of osteoporosis disease progression simulate...

background: implementing community-based psychiatric services is one of the priorities of the who/emro mental health programs. this study presents an aftercare service, as a community based-service, for patients with severe mental illness (smis).   methods : in this randomized controlled clinical trial design, 176 patients, who attended selective hospitals with smi, were allocated into three gr...

background: galactosemia is a congenital metabolic disorder that can damage the health of a newborn. screening is an important step to prevent and treat this condition. due to increasing health care costs and limited financial resources of health systems, the most suitable economic analysis tool should be applied. the aim of this study was to analyze the cost-utility of neonatal screening progr...

The Hotelling's  control chart, is the most widely used multivariate procedure for monitoring  two or more related quality characteristics, but it’s power lacks the desired performance in detecting small to moderate shifts. Recently, the variable sampling intervals (VSI) control scheme in which the length of successive sampling intervals is determined upon the preceding values has been proved t...
