Data envelopment analysis (DEA) is a method for measuring the efficiency of peer decision making units (DMUs) which uses a set of inputs to produce a set of outputs. In some cases, DMUs have a two-stage structure, in which the first stage utilizes inputs to produce outputs used as the inputs of the second stage to produce final outputs. One important issue in two-stage DEA is the sensitivity of...

Data envelopment analysis is a nonparametric technique checking efficiency of DMUs using math programming. In conventional DEA, it has been assumed that the status of each measure is clearly known as either input or output. Kao and Hwang (2008) developed a data envelopment analysis (DEA) approach for measuring efficiency of decision processes which can be divided into two stages. The first stag...

A retrospective review of all British Army patients presenting to the Queen Elizabeth Military Hospital with a diagnosis of Hodgkin's disease between 1977 and 1987 was performed, with a minimum follow-up of 7 years. The results were similar to those reported in other (similar) series, and the changes in investigations and treatment observed during this period matched those occurring in wider cl...

chronic kidney disease is one of the most common complication of systemic lupus erythematosus, which if untreated can lead to  the end-stage renal disease (esrd). early diagnosis and adequate treatment of lupus nephritis (ln) is critical to prevent the chronic kidney disease incidence and to reduce the development of esrd. the treatment of ln has changed significantly over the past decade. in p...

kaposi᾽s sarcoma (ks) can develop in 0.06% to 4.1% of kidney transplant recipients. here we describe a case of 50-year-old man who developed ks a few months after kidney transplantation . after transplantation, he had delayed graft function and was managed by anti-thymocyte globulin (atg) for five days. at the discharge, his immunosuppressive therapy was prednisolone 20 mg/day, ttacrolimus (ppr...

abstract in order to study the effect of density and time of nitrogen application on morphological, phenological characteristics, yield and yield components of black cumin (nigella sativa l) a field experiment was conducted at chenaran in khorasan razavi province in 2005 growing season. three nitrogen fertilizer (urea) application times (1- control 2- at 4-6 leaves stage 3-preblooming 4-complet...

data envelopment analysis (dea) is a method for measuring the efficiency of peer decision making units (dmus) with multiple inputs and outputs. the traditional dea treats decision making units under evaluation as black boxes and calculates their efficiencies with first inputs and last outputs. this carries the notion of missing some intermediate measures in the process of changing the inputs to...

background and aims: mental disorders may negatively affect on the quality of life in hemodialysis patients and their response to treatment. the aim of present study was to examine the prevalence of depression and related risk factors in hemodialysis patients. methods: in this cross-sectional study, during june 2013 to september 2013, 217 patients with hemodialysis whom were admitted to kerman ...
