The measurement of RTS amounts measures a relationship between inputs and outputs in a production structure. There are many different ways to calculate RTS in primal or dual space. But in more realistic cases, governments usually intervene on DMU’s behavior as regulatory agency, this clearly represent a set of limitations and restrictions on behaviors of DMUs, So very few decisions in DMUs are ...

introduction: due to increased costs of health sector, much effort has been done to compare the performance of hospitals and measure their efficiency in recent years. the purpose of this study was to evaluate the relative efficiency of public and private hospitals in qom during 2007 using data envelopment analysis (dea) approach. methods: this was an applied and analytic study. the study popula...

Study was conducted to assess the sensitivity and simplicity of various pain rating scales in patients of osteoarthritis with chronic pain so that most appropriate scale can be identified. Scales included were Wong-Baker Faces Pain Rating Scale (WBS), Numerical Rating Scale (NRS), Faces Pain Scale- Revised (FPS-R), Visual Analogue Scale (VAS) and Verbal Rating Scale (VRS). Patients were asked t...

Abstract In this study, variable returns to scale (VRS) data envelopment analysis was integrated into the Taguchi approach optimize ternary additives for expansive soil enhancement. The selected were sawdust ash (SDA), quarry dust (QD) and ordinary Portland cement (OPC). set as input variables while multiple responses obtained from experiments performed with orthogonal array output variables. E...

This study compared faculty perceptions and expectations of dental students' abilities using virtual reality simulation (VRS) to those who did not use virtual reality simulation (non-VRS) in an operative dentistry preclinical course. A sixteen-item survey with a ten-point rating scale and three open-ended questions asked about students' abilities in ergonomics, confidence level, performance, pr...

conclusions this study indicated that the modified version of the adult nvps in step with the vrs is a useful tool for pain intensity assessment in the ed. results the average age of the participants was 35.2 years, and the extremities were the most common painful area (66.2%). the mean vrs and nvrs pain intensity ratings upon arrival were 6.16 (± 2.63) and 3.06 (± 2.17), respectively. the esti...

BACKGROUND The most-widely used visual rating scale (VRS) for medial temporal atrophy is the T1-weighted (T1W) coronal VRS developed by Scheltens et al. However, it is often difficult to use the T1W-coronal VRS in cases with limitations in obtaining T1W-coronal images. To overcome this issue, we modified the T1W-coronal VRS onto the axial plane. OBJECTIVE The purposes of this study were to va...

the aim of this study was to assess the relative efficiency of the iranian forest management plans using the non-parametric method – data envelopment analysis (dea) as a well-known and robust technique for measuring the relative efficiency of organizations. the relative efficiency of forest management plans was calculated using the most frequency dea models such as global technical efficiency (...
