Irradiation treatment is one of the best techniques to extend the shelf-life of meat, without emerging the nutritional properties and sensory quality of irradiated meat products. However electron -beam may cause transformations in foods but has been known as to the most easily-applied irradiation technique in food industries. Electron-beam irradiation is an environment friendly, low cost and time effective alternative to other decontamination technologies. Lipid oxidation could produce of irradiated meat. This study aimed at evaluating the state of lipid oxidation of irradiated sausages. Its findings could help the control, improve food safety and quality properties to food industries.
Sausages were purchased in a local supermarket, minced sausages blended for thiobarbituric acid reactive substances (TBARS) analysis and divided into 25 g pieces. The samples including one control group and four case groups. Packaged sausage were exposed at doses of 0 (control), 1, 2, 3 and 5 kGy and analyzed on various days 0, 5, 10 and 30.
Thiobarbituric acid reactive substances (TBARS) has increased as time goes on (P Utilizing of Electron-beam irradiation in low doses does not have significant difference on lipid oxidation. Irradiating of meat products by addition of antioxidants can minimize or avoid the development of rancidity.

Irradiation of intervention strategies in order to effectively control food-borne pathogens are microorganisms that reduce microbial load and increase the shelf-life.
In this study, ostrich meat with electron beam 1.5, 3 and 5 kGy doses treated and were stored in temperature 1 ± 4° C for 15 days. With 5 day intervals after irradiation, chemical and organoleptic changes were evaluated. The amount of total volatile nitrogen (TVN) and thiobarbituric acid (TBA) were measured to evaluate the chemical changes.
Irradiation significantly reduces the amount of TVN in the samples were irradiated. It also increases the amount of thiobarbituric acid in the irradiated samples was statistically significant direct relationship with the irradiation and during storage, and despite the increase in thiobarbituric acid, irradiation had no significant effect on the sensory properties of ostrich meat..
The results show that electron beam irradiation of ostrich meat with increased storage time for at least two weeks at refrigerator temperature without a noticeable change in the organoleptic properties of the meat.

Lung cancer is known the leading cause of death among cancers. Since in our country a comprehensive scientific information not available on the determinants of protective behavior of lung cancer among workers, this study, aimed to examine determinants of lung cancer protective behaviors among Esfahan Steel Company (ESCO) workers based on protection motivation theory.
This cross-sectional study was performed on 253 workers of the ESCO who were randomly selected. In this study, the researcher-made questionnaire was used to assess determinants of lung cancer protective behaviors.. Collected data were analyzed by statistical tests of T-Test, ANOVA and correlation coefficient.
Of participants %54.2 have always did periodic medical examinations to ensure of their lungs health and 27.7% of participants used low-risk materials instead of hazardous materials. Among constructs of protection motivation theory, perceived severity had the highest mean score (41.33 ±5.83) and fear the lowest mean score (9.77 ± 2.49). The constructs of protection motivation theory predicted 22.6% of lung cancer protective behaviors variance.
Regarding effectiveness of the protection motivation theory in Understanding determinants of lung cancer protective behaviors so the theory can be used as a framework for the design of educational programs to enhance worker's motivation to adopt lung cancer protective behaviors.

Identifying the effect of energy consumption, economic growth and foreign trade on CO2 emissions have been studied at both national and international levels. However, there have been very few researches on the effect of financial and banking development on the CO2 emissions, especially in Iran. So, this study aimed to cover this research gap.
This study was a time-series analyses over the period of 1971-2011. In order to investigate about existence of a long-run co-integration relationship between CO2 emissions and banking development indicators in Iran, long-run coefficients were estimated by Autoregressive Distributed Lag (ARDL) and Dynamic Ordinary Least Squares (DOLS) approaches. Moreover, to carry out the econometric tests Microfit (5.0) and Eviews (9.0) software were used.
Findings showed that the ratio of domestic credit to private sector by banks to GDP (Banking Development Indicator) reduces CO2 emissions in Iran. In addition, results confirm with theories and other empirical studies showed that energy consumption has positive and significant effect on CO2 emissions in long-run.
The government can help to improve environment quality by establishing a strong policy making on credit to firms by banking system. Because in this framework firms to receive credit from banking system are required codified programs to reduce negative outcomes of energy consumption and this lead to a less CO2 emissions in long-run.

Sexuality education is one of the most important educational needs for adolescents, and mothers may have the key role in educating these issues to their daughters. This study aimed at developing, implementing and evaluating of a training program for mothers to educate sexuality matters to their adolescent girls in Mahshahr, Iran.
This field trial was conducted on 140 mothers having 12 to18-year girls from September to March 2012. Data was collected by two validated questionnaires. The first one assessed the “Parent-Child Relationship: Mother" questionnaire which indirectly measures the level of communication skills for mothers completed by the girls, and the second one measured "Knowledge and attitude about sexuality education to adolescents" questionnaire completed for mothers. Based on the results, an educational intervention for mothers consisted of three training sessions was designed and established. Before and three-month later data were analyzed and compared.
Three months after the intervention, the mean scores of mothers’ knowledge and attitude scores toward sexuality matters, was increased significantly (P It seems that the designed educational program was effective to improve the knowledge and attitudes toward the sexuality matters in mothers, but learning communication skills as an important factor in training women for sexuality education to their adolescent girls, need to continuous, regular, and companion with experiences and practice.

Congenital heart defects are known as the state that comes from birth and influences on structure and function of baby's heart, The different types of defects can range from mild (e.g., a small hole between the heart chambers) to hard (like a flaw or weakness in a part of the heart).
This article is a review article in which the articles published in Farsi and English that the bases valid as Medline, Google Scholar, Pubmed, Springer, SID index has been used, as well as for the study of keywords associated with the use of MESH keywords in identifying and no time limit listed in the databases were searched.
Result The prevalence of congenital heart defect, in general, less than one per cent in newborn. The ventricular wall abnormalities defect (VSD), atrial septal defect of (ASD), patent ductus arteriosus (PDA) and tetralogy of Fallot (TOF) Top among the most types of congenital heart anomalies. Factors such as the age of the parents at conception, maternal risk of diabetes, influenza and febrile illness during pregnancy, drug use during pregnancy and taking a multivitamin before and during the Pregnancy were influenced of newborns with congenital heart defects.
According to studies need to be conducted in the presence of multiple risk factors for these disorders, seem to have a detailed plan to Study of More about the factors that affect the risk of developing these disorders, as well as interventions to reduce risk factors identified particularly during pregnancy.
