- چکیده:
- چکیده انگلیسی: Nowadays companies looking for increase of quality, flexibility and timeliness. One way to achieve these goals is lean thinking. To implementation lean production, companies are looking for waste reduction and Continuous improvement. This article Using the technology acceptance model (TAM) examined whether management accountants’ perceptions of the perceived ease of use (PEOU), or perceived usefulness (PU) of value-stream costing may influence on their behavioral intention (BI) to implement value-stream costing. In order to data collection was used the Davis (1989) and Venkatesh and Davis (2000) questionnaire and structural equation model (SEM). Furthermore using PLS and analysis regression. Results show that don’t significance relationship between perceived usefulness (PU) and behavioral intention to implement value-stream costing. But there is significant positive relationship between perceived ease of use (PEOU) and behavioral intention to implement value-stream costing.

- چکیده:
- چکیده انگلیسی: Considering necessity of recognizing the knowledge-based economy and achieving its foundations in Iran, the main issue of this research is to clarify the relationship between intellectual capital and Refined EVA in insurance companies which are member of Tehran Stock Exchange. In this research, the Refined EVA index was used to evaluate and measure the intellectual capital of the Palick model and also to quantify the economic performance. Accordingly, information about 15 insurance companies during the period of 2011-2016 was analyzed to examine the relationship between these variables. The collected data are calculated using Excel software and analyzed with Eviews®. The results indicated that there is a significant and positive relationship between the components of intellectual capital (human capital, physical capital, and structural capital) with Refined EVA; as an issue that has a decisive role in the success or failure of companies in competitive markets.

- چکیده:
- چکیده انگلیسی: In This applicable research, investigating absorption of process of
Erythrosine dye on Copper oxide Nano particles Adsorbent was studied. First, prepared dye
concentrations of 6, 8 and 12 mg L-1 and then effects of parameters such as concentrations of
initial dye, time and pH on dye absorption efficiency were investigated.The dye
concentrations in different samples were measured via spectrophotometer (505.6 nm for dye
Erythrosine wavelength).
The results of absorption studies showed that Erythrosine absorption or removal rates
would increase with decreasing the primary dye concentration, increasing reaction time , and
decreasing pH on the basis of the results, copper oxide Nano particles can the absorb
Erythrosine dye appropriately and efficiency of the process is higher in acidic pH for dye
Erythrosine. The maximum dye removal of 93.68 % could be achieved at initial pH 2 using
adsorbent dosage of 0.233gr in 50 ml (12 mg L-1 dye concentration) and agitation rate of 180
rpm. Effect of different parameters as kinetic parameters, were calculated pseudo-First and
second-order kinetic, the Langmuir and Freundlich models Isotherm for absorb of this dye on
adsorbent. this results showed that second-order kinetic adherence possessing regression
coefficient of R2 ≥ 0.999, absorption or removal of Erythrosine on Copper oxide nano
particles and different parameters for investigating of process rate of absorption in to be this
experience. Equilibrium data fitted well with the Langmuir model for dye with adsorbent.- انتشار مقاله: 24-10-1392

- چکیده انگلیسی: Background and Aims: The production of science and research has always been one of the indicators of scientific progress that advances social, economic, social, cultural, and so on. The purpose of this study was to investigate the structural relationships between the performance variables of graduate students' performance with the performance of faculty members with the role of intermediate motivation for academic achievement and self-efficacy of students. Materials and Methods: The design of this research was relational. The statistical population of the study was all postgraduate students of the University of Tehran during the academic year of 1969-98. A total of 648 people were selected through stratified sampling. The research tools were questionnaire of student evaluation of teachers' educational performance, Educational Achievement Motivation Questionnaire, Commodity Inventory Questionnaire and Research Performance Questionnaire. The data was compiled using two spss and lisrel software. Results: The mean and standard deviation of students' research performance from 24 points were 4.77 ± 2.61. The structural effect of academic achievement motivation on self-efficacy and research performance was significant. The effect of teacher training performance on students' research performance was significant. The value of 0.17 of variance of research performance by model variables, 0.31 of self-efficacy variable was explained by the variable of motivation of academic achievement and teaching performance of faculty members, and 0.57 of the motivation variable of academic achievement was explained by the teacher's educational performance variable. The effect of educational performance of faculty members on the motivation of academic achievement and self-efficacy was significant on student's research performance. Conclusion: It can be concluded that the performance of teaching faculty is one of the important variables on other important educational structures of the students.

- چکیده:
- چکیده انگلیسی: Background and Objectives: The Increase of unnecessary caesarean sections has become one of the serious concerns in some health systems. One of the seven packages of the health Reform Plan that was sent to all Iranian medical universities in 2014 was the "Promoting Natural Delivery (vaginal births)," It emphasized the need to reduce cesarean delivery and promote more natural delivery. The present study aimed to assess gynecologists’ perspective on the Health Section Evolution Plan in Iran.
Methods: This qualitative study was conducted in 2015. Semi-structural interviews were used for data collection. 11 gynecologists of Isfahan University of Medical Sciences through purposive sampling were interviewed. Thematic analysis method was used for data analysis.
Results: After analyzing the content of the interviews, four main themes including “making the natural childbirth franchise free”, “reducing C-section rate”, “motivating service providers", and “improving the standards of natural childbirth facilities”, and 5 sub themes including “not giving attention to the culture” , “obligatory increase of natural delivery rate”, “not giving attention to some reform laws at the natural childbirth”, “an unacceptable tariff payment system” and “payment delays on new tariffs” were determined.
Conclusion: Promotion of natural childbirth instructions has somewhat realized; however it has serious shortages and limitations. It is possible to solve a lot of problems by increasing the number of vaginal births through developing legal guidelines to respond to the possible problems as well as seeking leg- انتشار مقاله: 28-09-1395

- چکیده:
- چکیده انگلیسی: Imidazole is a planar, five membered heteroaromatic molecule with pyrrole type and pyridine type annular nitrogens. Several approaches are available of imidazoles from alpha halo ketones, aminonitrile, aldehyde ect. Reactivity of imidazole and benzimidazole is referred from sets of resonance structure in which the dipolar contributors have finite importance.
Imidazoles among the principal groups of heterocyclic compounds that have biological properties. Due to the presence of imidazole rings in natural products and active pharmaceutical ingredients, different ways for the synthesis of heterocyclic compounds of this type investigated. The aim of this project is substituted derivatives 2,4,5-Imidazoles.
In this study, three-substituted imidazole compounds synthesized using ammonium chloride as a catalyst cost in terms of reflux were studied. Reaction with aldehydes and ammonium acetate Acenaphthene quinone in crowding conditions in the presence of ammonium chloride was performed successfully and imidazole derivatives were prepared with good yields. The key advantages of this process are high yields,cost effectiveness of catalyst,easy work-up and purification of products by non-chromatographic method.- انتشار مقاله: 02-12-1395
