Data Envelopment Analysis (DEA) is a nonparametric approach for measuring the relative efficiency of a decision making units consists of multiple inputs and outputs. In all standard DEA models semi positive real valued measures are assumed, while in some real cases inputs and outputs may take complex valued. The question is related to measuring efficiency in such cases. As far as we are aware, ...

Myocardial infarction (MI) decreases patients’ quality of life (QOL). The present study aimed to investigate the effect of relaxation training and exercise on QOL in post-MI patients. This single-blind, randomized, clinical trial was conducted on 64 post-MI patients at Fatemeh Zahra Hospital in Sari, Iran, in 2013. The study population was divided into two groups of intervention and control. Th...
