...Show More Authors

Objective: The study aimed to determine the effectiveness of preoperative psycho - education al
program on cardiac surgery patients information and their level of stress. And find out the differences
in the Psycho educational
program with regard to patients demographic characteristics such as age and gender.

preoperative education program on stress for cardiac surgery patients in Baghdad city from the 28th of
March, 2010 , to 19th of September ,2011.
The preoperative psycho - educational program, as well as the questionnaire was constructed as a tool of
data collection for the purpose of the study. Purposive (non probability) samples of 40 patients who
have undergone cardiac surgery (CABG &VR) are selected from Ibn AL-Bitar Specialized Center for
cardiac surgery. The researcher divided the samples into two equal groups (the study and control
groups) .
Data was analysis through the use of the suitable statistical methods.
Results: The results of the study indicates that there are significant differences in the patients
knowledge towards cardiac surgery in the study & control groups through pre-test, post-test.

Different Estimation Methods for System Reliability Multi-Components model: Exponentiated Weibull Distribution
...Show More Authors

        In this paper, estimation of system reliability of the multi-components in stress-strength model R(s,k) is considered, when the stress and strength are independent random variables and follows the Exponentiated Weibull Distribution (EWD) with known first shape parameter θ and, the second shape parameter α is unknown using different estimation methods. Comparisons among the proposed estimators through  Monte Carlo simulation technique were made depend on mean squared error (MSE)  criteria
