- چکیده انگلیسی: Introduction: Patient safety is a major component of healthcare quality, which is defined as the avoidance of causing harm to patients in providing healthcare services. The present study aimed to investigate the attitude of nurses toward the patient safety culture in the teaching general hospitals affiliated to Tehran University of Medical Sciences, Iran. Materials and Methods: This cross-sectional study was conducted in 2014. Data were collected using the adapted version of the safety attitude questionnaire (SAQ). Sample size consisted of 385 nurses, who were selected randomly. In total, 325 participants completed the questionnaire. Data analysis was performed in SPSS Version 19 using descriptive statistics, t-test, and analysis of variance (ANOVA). Results:Mean age of the participants was 36.21±6.9 years, and 92% and 8% of the respondents were female and male, respectively. In terms of the occupational status, 92.1% of the participants had a contractual job or permanent official employment. Mean percentage of the positive attitude toward the patient safety culture was 59.2±18.1, 55.6±17.0, 53.8±24.2, 49.5±16.5, and 43.0±22.4 in the dimensions of management perception, teamwork, job satisfaction, safety climate, and work conditions, respectively. In addition, a significant difference was observed in the dimension of management perception and employment status of the nurses (F=4.4; P=0.01). Conclusion: According to the results, attitude of the nurses in the selected hospitals was poor toward the dimensions of the patient safety culture. Therefore, it is strongly recommended that specific training interventions be performed to enhance the work conditions and safety climate in these hospitals

- چکیده انگلیسی: The perceived risk is assessed in order to conduct subjective evaluation of individual or community of probability of occurrence of accidents, crashes, and way of exposure to the related consequences. Although such estimation may not comply with what it occurs in real situation since this part is totally related to psychological aspect and at the same time it should be incorporated in planning for risk management. With respect to literacy, cultural, and gender levels and beliefs in communities, perception of the probable risk may be followed by some fluctuations. It has been tried in the present project to explore effect of factor of fear of disease on perceived possible risk among the people who live at neighborhood of MDF Manufacturing Companies. To analyze the rate of effect of fear of disease on the perceived possible risk at region and their relationship with demographic attributes including age, gender, education, having children, and employment in factory, the questionnaire with close-end questions of Likert spectrum type was administered. Data were analyzed by SPSS (v.16) and two-sample t-test and Pearson’s correlation coefficient and linear regression with (p

- چکیده:
- چکیده انگلیسی: Nanotechnology could be a very important field of recent research dealing with medical, industrial, environment. Silver nanoparticles are the topics of researchers because of their distinctive properties (size, shape depending optical, antimicrobial, and electrical properties). The synthesis of safe nanoparticles by biological organisms is recommended due to the environmental friendliness and low costs compared to physical and chemical methods. Recently, researchers tend to use a biological synthesis of nanoparticles by biological methods such as plants. This research aimed to study on the rainfall level on the biosynthesis of silver nanoparticles by Lamiaceae family plants in different regions of Iran. T-test student was used to examining the relationship between the size of nanoparticles and rainfall, using spss version 22 software. The study shows phenol concentration in low rainfall areas is more than high rainfall area, which is the main factor for the synthesis of nanoparticles. The result of the study demonstrated that the highest size of synthesized nanoparticle is 50 nm and the lowest size 10 nm, which are related to high rainfall and low rainfall regions respectively. The results showed the relationship between synthetic nanoparticles sizes and rainfall are significant p-value

- چکیده انگلیسی: The aim of the study " The Different Role of Mental Accounting on Optimal Portfolio Based on Speculative Bubble on companies listed in the Tehran Stock Exchange" is the 10-year study period listed in the Tehran Stock Exchange during 2008-2017 were analyzed.The data of 110 firms were analyzed by using statistical softwares including Matlab, spss20, Eviews7 and Lingo in the studied years. In this research, mental accounting is based on Fernandez, The speculative bubble based on the gilium pattern are used as a risk measurement indicator. The result of testing the above hypotheses showed that for the calculated returns because it is greater than the error level, the hypothesis of equality of the average returns of the portfolios is not rejected. In terms of speculation bubble (subject to speculation) based on subjective accounting there is no significant difference and efficiency based on standard deviation index is not higher. The result of the statistical test of these hypotheses shows that the significance value for the calculated returns is greater than the error level, the hypothesis of mean inequality of portfolio returns (research hypothesis) is rejected and in other words the speculative bubble portfolio returns (greater than Portfolio returns are not without bubbles.

- چکیده:
- چکیده انگلیسی: Objective: Cholesteryl Ester Transfer Protein (CETP) mediates the transfer of cholesteryl ester from HDL-C to LDL-C and VLDL-C. The aim of the present trial was to evaluate the effect of curcumin and its modified formulation on serum CETP concentrations in patients with metabolic syndrome.
Materials and Methods: Participants were randomly allocated to one of three groups of 40 subjects receiving either unmodified curcumin or its phospholipid complex or placebo. Lipid profile and plasma CETP were measured at the start and sixweeksafter initiation of the treatment.The normality of data distribution was assessed by Kolmogorov-Smirnov test. Wilcoxon test was used for comparing the data before and after the intervention. The percent changes of CETP and biochemical factors among the three groups were compared using Kruskal-Wallis test.
Results: Serum CETP levels were not significantly altered among patients receiving curcumin.
Conclusion: Curcumin and its complex had no significant effect on serum CETP concentrations.- انتشار مقاله: 11-03-1396

- چکیده انگلیسی: Portfolio theory assumes that investors accept risk. This means thatin the equal rate of return on the two assets, the assets were chosenthat have a lower risk level. Modern portfolio theory is accepted byinvestors who believe that they are not cope with the market. Sothey keep many different types of securities in order to access theoptimum efficiency rate that is close to the rate of return on market.One way to control investment risk is establishing the portfolioshares. There are many ways to choose the optimal portfolioshares. Among these methods in this study we use loss functions.For this, we choose all firms from the year2011to the end of 2015that had been a member in the Tehran Stock Exchange. The resultsof this research show that the likelihood functions have the bestperformance in Forecasting the optimal portfolio allocationprob-lem.
