in very recent papers asmild et al. (2003) and halved et al. (2004) based upon potential improvement efficiency index (bogetoft and hougaard,1999) have suggested an alternative nonparametric frontier approach namely multi-directional inefficiency analysis (mea) to estimate the performance efficiency. mea has many advantages over data envelopment analysis (dea) as the standard nonparametric fron...

Waste from raw materials has a direct influence on the final price of product. However, since waste no added value to products, customers are unwilling pay for it. Reducing along production process and supply chain allows companies decrease costs remain competitive in product prices. This research is conducted medical device manufacturing company located Tijuana (Mexico). The found negative var...

OBJECTIVE To assess the effectiveness of a feedback and educational intervention to increase documentation of clinical tumor-node-metastasis (TNM) stage among urologists in a statewide quality improvement collaborative. METHODS The Michigan Urological Surgery Improvement Collaborative (MUSIC) is a consortium of urology practices that aims to improve the quality and cost-efficiency of prostate...

Objectives: The present study examined the effect of home-based handling training of mothers on the improvement of gross motor function of children with Cerebral Palsy (CP). Methods: In this randomized control trial, 42 children with CP (5-12 years old) were randomly assigned into the intervention and control groups. Data were collected using the Gross Motor Function Classification System and ...

results before the intervention, there were no significant differences between mothers in two groups (p > 0.05). after 8 weeks follow up, a significant improvement appeared in mothers’ sleep quality in the intervention group. aromatherapy increased sleep quality mean score (±sd) from 8.2911 (± 2.1192) to 6.7975 (± 2.3663) (p < 0.05), but in the control group sleep quality mean score (±sd) chang...

In most industrial zones, electric energy is one of the most important energy sources. Since electrical motors are the main energy consumers of industrial factories, consumption optimization in these motors can be considered as a main option related to energy saving. One very effective way to reduce the consumption of these equipment is to use a motor speed controllers or drives. Since the loss...
