Knowing the components of ECONOMIC education provides the dynamic background of education in this field. The aim of the current research is to investigate the indicators and components of the ECONOMIC education curriculum. The approach of the current research is qualitative and its method is research synthesis. The research community is all the articles (211 articles) that have been presented from 1390 to 1401 AD and from 2010 to 2022 AD regarding ECONOMIC education in curricula. The sample of the research is 32 articles, which were selected based on thematic monitoring, theoretical data saturation, and purposefully. The research data were collected from the qualitative analysis of the studied articles. By analyzing the data, the dimensions of vitality in the curriculum of the elementary school in 4 factors and 55 categories including the dimension of individual factors (including indicators and components related to personality characteristics); The dimension of culture and ECONOMIC ethics (ECONOMIC fields in the society); The dimension of ECONOMIC concepts and knowledge (indices in ECONOMIC education) and the dimension of collective and communication concepts (communication and interaction indicators in education) were classified. ECONOMIC education is dependent on internal and external components in educational systems, which requires macro-planning in this field.

This research aims to investigate the long-term impact of Brainard's uncertainty and banking STABILITY on Iran's ECONOMIC growth; Therefore, it is practical in terms of purpose and analytical in terms of causal type. The statistical population is all the banks admitted to the Tehran Stock Exchange. The model presented in this research includes four sectors: households, companies, banks and the government. Thus, the stochastic dynamic general equilibrium model was designed according to the long-term conditions of Brainard's uncertainty, monetary policy and research objective. For this purpose, first the utility function of the household was explained and then the optimal equations of the household sector were extracted from the utility maximization process according to the budget constraints. After that, the production function was explained in terms of the assumption of price and wage inflexibility competition, and optimal equations were obtained from the company's profit maximization process. Also, the banking sector was added to the model, which is one of the initiatives and innovations of the present research. The banking sector, like a producer, seeks maximum profit, and through this, the optimal equations of this sector were also obtained. Finally, the government and central bank were also added to the model according to the conditions of Iran's economy. To solve the model, first all the equations must be linearized, so in the next step, the linearization process was done in different ways. The next step is to determine the parameters of the model, which was obtained from the combination of calibration and estimation methods, and the model was solved using the random dynamic general equilibrium model solution methods

Milling processes are becoming one of the common manufacturing methods in industry. One of the main goals in any manufacturing operation is to increase productivity. In high speed low immersion milling, the ratio of cutting edge engaging time to spindle period is a small value. For this kind of operations, two types of: InSTABILITY are proposed: classical Hopf and the Flip bifurcation, which are mainly due to impact effects of entering/exiting of the cutting edge into the cut. In order to increase productivity, it is essential to anticipate stable machining boundaries. In this research, the main goal is to derive and implement the improved TFEA method to include the effects of the helix angle variations for a 2-DOF vibratory system and accurately compute the STABILITY lobe diagram. Results obtained by SIMULATION witnesses that inSTABILITY due to Flip bifurcation vanish completely from STABILITY lobe diagram with increasing helix angle to 30°. Experimental tests are conducted in order to confirm the result obtained by the improved TFEA method showing good agreements.

Introduction In recent years, metropolitan and urban areas of Iran have experienced incomplete urbanization that has been the result of oil capitalism. The level and scope of urban sprawl has raised concerns among managers and citizens. It is obvious that the uncontrolled growth of cities has not only changed the landscape of cities but also has caused fundamental changes in the ECONOMIC pattern of the city and surrounding villages. This issue has also had an increasing impact on the functional developments and the economy of these areas. This resulted in consequences such as poverty and abnormality, unemployment, wide gap in living standards, inequality in areas, etc. Meanwhile, the city of Tehran is experiencing the suburban phenomenon and the negative effects of urbanization such as rapid environmental decline, unplanned land-use changes, severe service shortages, migration, class gap, unemployment, working children, etc., are elevated.  The amount of migration to the metropolis of Tehran made surrounding areas absorb the overflow of development from Tehran, so they have quickly become cities by attracting migrated population. Islamshahr city, unlike other old cities, has not been created due to its natural and environmental capabilities, but the emergence of this city due to its location in proximity of Tehran, where became a residential destination for thousands of migrated people who have entered this area due to repulsive factors in Tehran such as land and housing. In this research, the ECONOMIC indicators of the suburbs of Islamshahr have been assessed using factor analysis and TOPSIS.   Research Methods This research is an applied and developmental study and in terms of method is descriptive-analytical. The study area is the inhabitants of cities and villages in the suburbs of Islamshahr. The information required for this research has been obtained from library sources, the results of general censuses, referring to various departments and organizations, and the census of residents of the study area. 25 indicators have been extracted which have been transformed into 3 factors using factor analysis model. Instead of using the conventional method of principal component analysis in factor analysis, the standard method has been used to obtain factor scores,In the next part of the model, similarity to the fuzzy ideal option (FTOPSIS) is used. The statistical population in this study is the residents of cities and villages in the suburbs of Islamshahr, which have a population of 492,145 people, which according to the Cochran's formula, the sample size has been determined as 384 people.   Results and discussion The eigenvalue of the first factor is 11.524, which calculates and explains 52.848% of the variance. In this factor, 17 indicators have been loaded and considering that some indicators are among the welfare indicators and others are among the trade indicators, this factor has been named as trade and welfare factors. The eigenvalue of the second factor is 7.321, which calculates and interprets 29.645% of the variance. This factor has five loaded indicators, all of which are demographic indicators that can be called the population factor. The eigenvalue of the third factor is 3.846, which calculates and interprets 13.141% of the variance. In this factor, three indicators are loaded, all of which are industrial indicators. Therefore, this factor can be called an industrial factor. The results of fuzzy TOPSIS calculations and the similarity index (CI *) confirms the high rate of gap in the process of ECONOMIC sustainability. Among these, the best similarity index (0.79) is related to the city of Islamshahr, which has made this region higher than other regions. Also, the lowest similarity index is related to the ratio of active to inactive population (0.460), which is in the most deprived metropolitan area of ​​Islamshahr in terms of indicators of ECONOMIC STABILITY. In general, the amount of ECONOMIC STABILITY according to this analysis is equal to 0.45, which is lower than the average (0.5). This shows that the area of ​​Islamshahr is not in a good position in terms of ECONOMIC STABILITY.   Conclusion Based on the results obtained from multivariate regression, respectively: 1- commercial welfare factor, 2- demographic factor, 3- industrial factor. They have the largest share in predicting the degree of enjoyment of the suburbs of Islamshahr. Therefore, commercial, demographic and industrial welfare factors are suggested as a priority for the development of this region. According to the results of the research and the issue of justice, as well as citizens' access to facilities and services, the following suggestions are presented: 1- Using the reverse justice in a way that has the priority of ECONOMIC development of low-income areas. 2- ECONOMIC policies should be in line with the spatial planning of Tehran and Islamshahr. 3- Recognizing the potentials and capabilities of each region and planning and investing in them and of course the appropriate productivity of each region. 4- Planning to reduce the unemployment rate in the regions and increase the employment rate.

Achieving a sustainable ECONOMIC STABILITY and strengthening the economy against the menace of negative and positive shocks is considered to be one of main priorities of policy makers of Iran in toto. It is obvious that macroECONOMIC vulnerability will lead to uncertainty of ECONOMIC agents regarding the future developments of the country and will have a negative impact on investment trends and ECONOMIC growth per se. On the contrary, the macroECONOMIC STABILITY can mitigate the ECONOMIC uncertainty and promote the long term growth, Ipso facto.The ECONOMIC sanctions of west which imposed on Iranian economy had devastating impacts on both real and nominal sectors of the economy. Thus adoption of appropriate strategies to deal with that and restoring the economy to its long-term equilibrium path is bearing a dire importance for policy makers de jure. In this context, one of the essential policies which designated by the authorities of Iran, was the implementation of ECONOMIC resilience approach within a composed system against the jeopardy of stochastic external and internal shocks Sui generis.The results of this study prima facie indicate that the enactment of ECONOMIC resilience policy and acquiring its optimal consequences requires long-term meticulous planning coordination of all ECONOMIC sectors and enhancing the ECONOMIC ex-efficiency. However, the Iranian economy is replete with various structural and infrastructural bottlenecks, which can be rectified viz-a-viz institutional underpinning, homogeneous norms of ECONOMIC agents, well articulated value system, sense of sacrifice to the community, glorification of work culture and sincere contribution of people to the productive common pool, pro rata.

The paper intends to answer this question: given the current facts and realities in Saudi Arabia, which changes are probable in the field of ECONOMIC development and political STABILITY of the country? The author assumes that the in the short term the current ECONOMIC situation will go on and the government’ s dependency on oil will not be aborted. The Saudi government enjoys the oil revenues for the public well-being as well as gaining legitimacy and political STABILITY. However, some of its officials are of the view that with should the status quo continue, both the national well-being and political STABILITY will be at risk in the near future. Therefore, it is the time to transiting into a competitive and economy together with a variety.

For safe underground excavation, different supporting systems can be used in weak ground conditions. However, rock mass inSTABILITY does not give opportunity to install an appropriate supporting system. Because, tunnel face collapses and moves suddenly toward into tunnel. Different approaches and methods has been developed to prevail over this condition including sequential excavation of tunnel face, grouting of unstable and loose zones behind the face, using inclined longitudinal elements above tunnel crown prior to excavation known as arch umbrella elements methods, installing a pre-cutting system, and pre-reinforcement of tunnel face by fiber glass longitudinal elements. These methods may be employed either alone or together according to the severity of the problem. Fiber glass dowels are one of the most efficient and ECONOMIC methods of above mentioned approaches. Fast installation, flexibility in using with other supporting systems … are the other advantages of this pre-reinforcement. Although numerous studies have been conducted to evaluate and quantify the effectiveness of this method, some aspects such as evaluation of the tensile force induced in the dowels has not been studied. In fact, a correct dimensioning and evaluation can be obtained through three-dimensional numerical modelling. Hence, this paper studied numerically the behavior of the longitudinal fiber glass dowels installed uniformly at tunnel face along tunnel axis and may accompanied with the different supporting system i. e. with shotcrete layer as the main supporting system or with arch umbrellas or pre-cutting system as the other pre-support method. The analyses was carried out by FLAC 3D in different weak ground condition, say the class IV in Binyavsky category, subjected to three different in-situ stresses implying tunnel depths. As well, four lateral stress coefficient were chosen in the analyses. The fiberglass forces as well as tunnel center displacements are the output of this SIMULATION. First of all, the obtained results from the numerical SIMULATION in hydrostatic stress condition were verified by one of the previously presented analytical methods, then analyses were extended to non-hydrostatic stress condition. The results showed non-hydrostatic stress causes non-uniform stress and displacements in the face. As a result, the location of critical zones developed in tunnel face. It leads to employ more dowels on those zones. On the other hand, as lateral coefficient increases, the maximum stress of the dowels and strain of tunnel center increases. The maximum strain and stress occur at k0=2. However; critical zone can be developed at the tunnel crown at k0=0. 5. Therefore, with increasing the lateral coefficient, critical zone moves toward the tunnel sides. As well, the best result for the dowels could be seen when they were accompanied with pre-cutting system. It is more highlighted to notice that using dowels in more deep tunnels subjected to great lateral stress (say very squeezing condition) is not sufficient (because they yield) but must be accompanied with other system. Finally, from the results of numerous analyses, mathematical formulations were presented to fast calculate the maximum stress of dowels and strain of the tunnel center in any different condition of weak ground condition.

Air pollution has harmful effect on human health and the environment. Accordingly, considerable effort has been put to analyze the air pollutants. One important issue is the spatial distribution of these pollutants. Dispersion of the pollutants released from sources on the ground is mostly driven by the planetary boundary layer where turbulent flow causes mixing of the content of the stationary ground layer of atmosphere with higher moving layers and thereby clears out the pollutants rapidly. To predict the dispersion of air pollution in the atmosphere, researchers investigate the behavior of plume rise under certain conditions.
