The aim of this study was to estimate of (Co)variance components for egg production curve parameters and their genetic correlation with some economic traits using of the best function for describing egg production curve in wild strains of quail. For this purpose, the daily records of quail egg production during the first 20 weeks were used for fitting egg production curve. Five nonlinear functions including nonlinear logistic, incomplete gamma (Wood), modified compartmental, modified gamma, and logistic (Nelder) were fitted by R computer program, and the best function was determined based on the goodness of fit criteria. After selecting the best model, the production curve parameters for each of quails was calculated and their genetic correlation with age and weight of puberty, egg number, total egg production and the average egg during the first 20 weeks were estimated. The genetic correlation between traits was estimated using of a two-trait animal model and Gibbs sampling method by Gibbs3f90 software. Based on the goodness of fit criteria, the Modification of Wood was selected as the best function. Heritability estimates for the rate of production decrease was higher than the rate of production increase (0.231 in comparison with 0.148) and the heritability for weight of puberty was estimated higher than the age of puberty. Also, the heritabilty of egg number was estimated higher than the sum and average egg weight among the studied production traits. The highest and lowest genetic correlation was observed between the rate of production decrease and the rate of production increase (-0.764) and the rate of production increase with weight of puberty (-0.031), respectively. The results of the study indicate that the sum and average egg weight and age of puberty could be considered in selection objective to improve the egg curve parameters.

Evidence-based performance requires that Clinical staff in different areas of teaching, clinical and management learn the skills of using the evidence from the research and apply these. The purpose of this study was to determine the relationship between learning style and evidence-based performance in nurses working in Kermanshah hospitals. This study was performed on 319 nurses working in hospitals affiliated to Kermanshah University of Medical Sciences in 2015 by stratified random sampling and proportional assignment. The data gathering tool in this research was questionnaires include: the learning style of VARK, Evidence-based performance and demographic data form. Validity and reliability of the VARK learning style questionnaire have been confirmed in the country and abroad.
Validity of evidence-based performance questionnaire was confirmed through content validity and the test-retest method was used to determine the reliability of this questionnaire. Data analysis was performed using the VARK learning style analytical tool in Excel, Spearman correlation and Chi-square tests. The learning style of single-mode template (84.1%) and hearing-type with relative frequency (46.3%). Knowledge about evidence-based performance (53.2%) was moderate in nurses Attitude (52.6%) of people was positive about evidence-based performance. The evidence-based practice nurses (57/8 %) were nearly desirable level. There was no significant relationship between nursing learning styles and evidence-based performance (p = 0.926). Nurses have different learning styles. The development of Effective educational methods adapted to the learning style will help increasing their evidence-based performance by increase nursing awareness. Principled and systematic training to raise awareness and improve attitudes toward evidence-based performance and Nursing education also seems to be essential in terms of the concepts of evidence-based practice, scientific and workshop training, and the creation of facilities.

The chronic disease self-management program is among the most important methods for promoting self-care.
This study was done to evaluate the effects of this program on patients’ health status after undergoing coronary artery bypass graft surgery.
Patients and This one-group pretest-posttest clinical trial was conducted in 2013 on 46 patients, who had recently undergone a coronary artery bypass graft surgery and had been referred to the cardiac rehabilitation center of Imam Ali (PBUH) Hospital, Kermanshah, Iran. The participants were recruited conveniently and were educated based on the chronic disease self-management program. The data were collected using a demographic questionnaire and the health status questionnaire and were analyzed through conducting the Chi-square test using the SPSS software (v.21.0).
The chronic disease self-management program had significant effects on the participants’ general health, daily activities and pain (P The chronic disease self-management program significantly affects various health-related parameters. It is an inexpensive non-invasive intervention, which complements conventional medical treatments and thus, can be used by rehabilitation centers.

Chronic disease self-management program is one important way to improve and enhance self-care. This study aimed at evaluating the effectiveness of the program on self-efficacy of patients with coronary artery bypass graft (CABG) surgery. This clinical trial, as a before and after approach, was performed on 46 patients with a history of coronary artery bypass graft surgery referred to cardiac rehabilitation units of Imam Ali hospital. Sampling was based on a convenience method. Education was performed based on chronic disease self-management. Data was collected by general self-efficacy questionnaire and demographic form. Then, the data was analyzed with chi-square test and repeated measures of ANOVA using SPSS software version 21. The finding showed that most participants were men, married and living in Kermanshah. After conducting the program, the average score of the participants’ self-efficacy showed improvement, but the difference was not significant. This study demonstrates that chronic disease self-management program for patients is not effective.
