In this applied study, analysis of Iranian society and its threshold of tolerance has been done in a descriptive-analytical method. The society were professors of universities and the sampling size were 133. Data collection was done in archive and field methods. The reliability of the questionnaire was 89%. A multilayer perceptron artificial neural network was created to predict and model the human development index of the 38 target countries. Four input parameters were life expectancy at birth, expected years of schooling, mean years of schooling, and gross national income per capita". The response parameter was the human development index. The 4000 structures were developed, trained, validated, and tested by changing the variables of activation function, training function, and the number of neural neurons in the hidden layer. The optimal neural network in terms of network performance measures was the network with mean absolute percentage error (MAPE = 0.01156), Normalized Root Mean Square Error (NRMSE = 0.00124), and R squared (R2=0.99620). The optimal network had ten neurons in the hidden layer, a tansig activation function, and an RP training function. The artificial neural network model had a high accuracy in predicting the human development index. Based on the results of sensitivity analysis, the most influential factors were mean years of schooling, "life expectancy at birth, expected years of schooling, and gross national income per capita, with the relative importance of 33.63%, 24.43%, 23.83%, and 18.11%, respectively.

The governance experience of the Islamic Republic of Iran in foreign policy refers to the influence and interaction of this political system with other countries in international affairs. This includes policies, decisions, and actions taken by Iran in its relations with other countries and international organizations, covering diplomatic relations, international negotiations, agreements, sanctions, and influence on regional policies.The main goal of this research, titled Governance Experiences of the Islamic Republic of Iran in Foreign Policy, is to present a new model of foreign policy governance based on experiences from the establishment of the Islamic Republic. The primary research question focuses on examining the ideal governance model in foreign policy with Western powers, especially the United States.The methodology used is content analysis. The findings suggest a model consisting of three levels:a) Fundamentals: The power of God, divine principles, national interests, reinterpreting principles, finding common grounds for cooperation, and supportive defense-military power.b) Strategies: Anti-hegemony convergence, combining soft and hard power, and unity in foreign policy leadership.c) Outcomes: Weakening Western hegemony, strengthening resistance networks, enhancing the defensive-diplomatic axis, and maintaining consistent policies.In conclusion, the research shows that the ideal governance model in foreign policy with Western countries includes specific fundamentals, strategies, and outcomes that can help achieve Iran's objectives.

The purpose of this research is to examine the exchange rate increase, exchange rate gap, and exchange rate fluctuations in creating a foreign trade advantage within the framework of the resistance economy system based on modeling exchange rate fluctuations. We are seeking to answer the question of whether exchange rate changes affect asset returns within the framework of an asset pricing model based on foreign trade in the resistance economy system? If they do, is this effect positive or negative? Resistance economy is a literature that has been proposed in confronting international sanctions. Currently, the Iranian economy must step on the right foundation and principles so that it can overcome international sanctions and turn the threat of sanctions into an opportunity. Those principles and foundations that the Iranian economy must have have created a literature called resistance economy. Monetary and fiscal policies must be specified in this economic literature and we must always answer the question of what we are looking for in the policies we implement. In order to understand what monetary and fiscal policies should be like and what direction they should follow, we must first have a proper understanding of the Iranian economy and the main problem of the Iranian economy. For example, a policy is implemented with a goal, but then it becomes clear that not only have we not reached the goal, but we have also moved away from it.

The question that is discussed in the research is to what extent is it possible for Iran to model China's economic development model in the light of strategic cooperation between the two countries? What are the areas and obstacles in Iran's approach to modeling China, especially in the field of economic development? According to the hypothesis, it seems; The mutual economic needs of Iran and China, joint criticism of the existing international order, China's important role in attracting foreign investment, the One Belt/One Road economic plan, the position of the Middle East in China's energy supply, and political and security cooperation were mentioned as role models. In contrast to the variables; The different cultural structure of the two countries, institutionalism in Iran's economy, the quantitative and qualitative demographic structure of the two countries, the different economic structure, the social mistrust of Iranians towards economic cooperation with China, international sanctions against both countries, the influential weight of the level of trade China and America as a sanctions-oriented power, China's emphasis on the political geography of countries in the matter of economic development and its lack of modeling, and ambiguity in the foundations and real intentions of China's economic development model, as important obstacles to the feasibility of modeling China's economic development model. It is discussed.   The nature of this research is descriptive and analytical and it is discussed in the framework of the theory of interdependence. The method of collecting information and resources of this research is qualitatively based on library and internet resources. Finally, the method of analyzing the collected information is also done qualitatively.   In order to understand the nature of the relations between the two countries China and Iran and especially the interest that Iran has shown to cooperate with China, the theory of interdependence is a theory from which the possibility of adapting Iran's economic development model to China can be examined. gave However, it will be pointed out in the following that the mutual dependence of Iran and China faces important obstacles, which raises the question of how far it is possible for Iran to follow China's model of economic development, and what are the obstacles. Is there a field?   With the investigations that were done, in examining the possibility of following the model of China's economic development, there are many fields and obstacles that understanding the perspective of the interactions between the parties requires paying attention to the influential variables in this field. In the field of cooperation between the parties, we can mention things such as the mutual economic needs of Iran and China, joint criticism of the liberal economic system, China's important contribution and role in helping to attract foreign investment, the perspective of the One Belt/One Road economic plan, the position He mentioned the Middle East and Iran in China's energy supply and political and security cooperation between the parties. On the other hand, it seems that the obstacles to Iran's imitation of China's economic development model cast a shadow on the future of the relations between the parties. In this framework, different cultural structure, institutional avoidance, different economic structure, adoption of parallel laws, social mistrust, international sanctions, interweaving of the economy of China and the United States, China's emphasis on the political geography of countries in economic development and ambiguity in The fundamentals and real policy of China's economic development model were pointed out. In the end, it is worth mentioning that the decision makers and the government of Iran are still looking for local and international solutions and models for economic development. Of course, although there is no consensus on the principle of accepting the concept of development in the country yet, the necessity of economic development is still emphasized in the declaration field. In the meantime, China as an emerging economy is becoming an economic development model for some countries that want a different experience. For Iran, the possibility of imitating China's economic development model depends on the major areas and obstacles that need to be carefully considered in studying this issue. Even though the text mentions both the positive components and the obstacles of modeling, it seems that due to the lack of transparency in China's strategy regarding its intention of economic cooperation in other countries, the weight of the obstacles to the feasibility of modeling is greater than its opportunities. . Because some believe that China is trying to start economic cooperation with countries through debt trap diplomacy, especially in the form of the Silk Road project, and then by paying loans with heavy interest, it will force countries to follow China's economic decision-making models. . In this research, from the above approach to livestock policy, it is mentioned that the model of economic development is compulsory. In fact, in modeling the economic development model of China, it is considered important to model according to the domestic economic and political situation. It seems that even though China claims that the economic development model is different according to the political geography of each country and it is not possible to apply a common version for all countries, but in practice, China is inclined towards economic cooperation with countries that, within the framework of cooperation, its economic interests It should be prioritized and countries cannot have other alternatives for their cooperation through the financial aid they receive. Therefore, in this research, the dual path of voluntary modeling and mandatory modeling is predicted as the two paths and ways forward for Iran's economic development in cooperation with China, and the requirements and challenges of each of the above two paths are worthy of attention.

Gasoline is considered one of the most important and strategic products that is produced in oil refineries and among the consumption of energy products, motor gasoline consumption in Iran alone has a share of about 43%, so the most attention to effective management is required. The trend of increasing gasoline consumption in 1401 sounded the alarm to enter the channel of gasoline shortage and forced to import this product and may lead to the loss of export opportunities. Also, population growth puts considerable strain on available resources and significantly affects climate change. Besides, the oil, gas, and petrochemical industries are one of the most polluting industries in the world. Therefore, in recent years, the effective implementation of sustainable methods in the supply chains of this industry as one of the solutions to meet these environmental challenges has been considered by researchers and practitioners in this field. Hence, one of the most important activities is to try to model and ultimately optimize these chains. The present study aims to be able to provide a framework for the development of a mathematical optimization model of the country's sustainable gasoline supply chain. Therefore, in addition to providing an executive framework, it also deals with the methods of data collection and analysis of each of the executive steps of the proposed framework. By using the proposed framework, the goals explained in the strategic document of comprehensive energy planning of the country regarding the adoption of optimal and sustainable strategic decisions can be achieved.

Modeling the national power using explicit mathematical equations is very difficult. Artificial neural networks can solve complex multi-dimensional problems. In this applied study, The population was professors of the military, social sciences, economics, and geopolitics specialties. The sampling method and the sample size were randomly and 133, respectively. Data collection was done in archive and field methods. The reliability of the questionnaire was 89%. The obtained data were modeled by a multilayer perceptron neural network with nine input parameters including the dimensions of national power, and a response parameter i.e., the national power of the target countries. The 8000 neural network structures were developed by changing the variables of activation function, training function, and the number of neural neurons in the hidden layer. The results showed that the best neural network characterizations were the tansig activation function, LM training function, and 16 neurons in the hidden layer. The efficiency values of the network were MAPE = 0.00071, NRMSE = 0.00006, R2= 1.00000 in the training stage, MAPE = 0.00579, NRMSE = 0.00137, R2= 0.99999 in the test stage and MAPE = 0.00300, NRMSE = 0.00124, R2= 0.99997 in the validation stage. The relative importance of the national power dimensions were military 15%, scientific 13%, territorial 13%, cross-border 12%, social 11%, economic 10%, spatial 10%, political 8%, and cultural 8%. Based on the results, the optimal neural network model could predict the national power of the target countries with very high accuracy.

The purpose of the research is to design a model for strengthening the political capital of public administrators, which is descriptive-exploratory and mixed research in terms of practical purpose, and in terms of data collection. According to the principle of theoretical adequacy, 11 people were selected for the interview with the non-probability sampling method. In the quantitative part, the questionnaire was distributed among 25 experts. The results showed that the characteristics of managers, including: respect for people's rights, religiosity and religious thought, justice, work health, political attitude, economic management and transparency and accurate information to people have an independent role in the model, and factors Political support of parties and... from the government, acceptability and personality, authority and executive power, political legitimacy, social capital, attention to the development and development of the country, people's trust, cultural capital and general participation of the people in elections, and..... ... had a dependent role in the model.

Criminal description is one of the most important types of description that a method should be used to regulate it. Modeling and modeling is the best way to systematize specific criminal description. This study introduces the modeling of specific criminal law with emphasis on the description of regular criminal law and has modeled it in a crime against security (crime of moharebeh). Descriptive and data collection was done by reviewing documents and taking notes. In the proposed model of the present study, each crime consists of three parts or components, the first of which is the criminal title, which is the same as the accusatory title in the applied stage of the prosecution. Criminal titles can be divided into two categories: explicit and implicit, which can almost be said that previous studies have not examined this model and have considered the first component as a legal element. Regarding the second and third parts of this model, which is the material and psychological element, a special organization has been done which has been described in detail in the research; But the point that is more visible in this research is that the description components are regularized and by using this model, it is possible to easily identify complex crimes such as cyber-crimes and crimes against security, etc.

Governance is a multifaceted concept that includes all aspects of the exercise of authority, each of the dimensions of efficiency and effectiveness of the components is divided into administrative, economic, political and social domains, which shows the emphasis on the multifaceted nature of governance. governance is a subset of governance in which public resources and problems are managed effectively and efficiently in response to the vital needs of society. What are effective factors of good governance based on the ideas of the Islamic Revolution? , the confirmed hypothesis is that, according to the political ideas of the Islamic Revolution of Iran, there is enough capacity to provide a local model of good governance. It is done with the aim of improving components according to the approach of Islamic revolution thoughts. Due to the selection of the exploratory mixed approach of qualitative data, in addition to removing the importance in the sequence of data collection, first qualitative data and then quantitative data were collected. In the qualitative phase, among the strategies of qualitative research, meta-composite technique was used and a comprehensive model was developed which is the effective factors on good governance according to the approach of the Islamic Revolution thoughts. In-depth interview was used as a data collection tool. governance requires a multilateral approach with several systems of checks and balances that can be achieved through the separation of powers of various institutions, through the participation of civil society, the media, and through partnerships or agreements with the business sector.

The purpose of this research is to combine instant purchase in the Iranian retail industry with a focus on model extraction. The research method is survey.

Today, industries, especially the banking industry, are facing a much more complex environment than before, and in order to gain a competitive advantage, they have to adapt to changes in the environment. The comprehensive banking model is one of the most important new banking approaches implemented in many world-class banks. The research has expanded the role of banking in our country's banking industry by presenting a comprehensive banking model. The statistical population is the banking system of the country. The banking industry of the country and the application of BWM techniques, fuzzy graph, fuzzy demitel, scenario writing, etc., the relationships of the components were determined and the final structure of the model was presented. Comprehensive banking was identified in three operational levels: low, medium and high, which were provided to experts using fuzzy graph method to start fuzzy dimethyl stages. Then, using the hybrid method of fuzzy dimethyl and fuzzy graph, the relationships of 11 factors in comprehensive banking were determined and in the next step, the coefficients obtained from the fuzzy graph were provided to experts and the steps of structuring the factors were performed by fuzzy dimethyl. Factors of employees 'ability to make decisions Acceptance of responsibility in decision execution Employees' access to tools related to decision-making and implementation and control based on feedback were highly interrelated, and rewards of participation training were more interdependent than the previous two categories.

Writing has always been an integral part of learning and language learning in particular. Yet, it has something to be desired when it comes to teaching and learning it. This paper is an inquiry into the role stylistic imitation, i.e., imitating a writer’s style, plays in learning how to write in English classes. To that end, the researcher, taking advantage of action research to collect and analyze the data, has made an attempt to teach paragraph writing to EFL in-service teachers using stylistic imitation. Fourteen nonnative English teachers were asked to do close and free imitation; i.e., they produced a written piece at the beginning, freely following a paragraph prepared by the researcher. Then, they were exposed to the model paragraph and tried to imitate it closely and freely to see how exposure to a well written paragraph can improve writing competence. The researcher, following content analysis procedures, analyzed the data to find answers to the research questions. It was revealed that close imitation can help learner master the target structures. Furthermore, the findings from free imitation phase indicated that stylistic imitation benefits the less proficient more in that it helps them develop a style of their own. The implications in the educational settings are also discussed.

Measuring the impact of various factors on pension systems is not easily possible due to the multiplicity of influential variables and their change in long-term horizons. The purpose of this article is to provide a model by which the impact of early retirement laws on the pension fund can be predicted.

This study, using system dynamics and considering feedback loops, leads to understanding nonlinear behavior and recognizing the laws governing the phenomenon of early retirement, and designs and implements a model for analyzing the impact of the above pensions in the Social Security Organization. It seems to have the characteristics of the real world to a large extent.

The ratio of early retirees to ordinary retirees in 2051 will increase significantly compared to 2016.Increasing early retirement will also lead to a reduction in Insured and increase in retirees and survivors; So that an increase of one percent can reduce the organization's annual revenue by an average of 16,000 billion rials over the next 35 years.

The Approval of some laws, regardless of the consequences, can jeopardize the stability of the fund and the economic and social security in the long time. The model presented in this study shows that by maintaining the current situation, the demand for early retirement has an upward trend and will put a heavy financial burden on the organization. This issue requires the amendment of the above laws and the introduction of more restrictions on the use of early retirement.

Given the current state of the country's economy and the serious need for operational planning to combat economic corruption, it is necessary to take effective practical steps to combat economic corruption by identifying the root causes of economic corruption and leveling these factors.In this article, which is the result of an operational and strategic research in the field of identifying the factors affecting economic corruption and their leveling; First, we identify the causes of economic corruption and then according to the opinions of experts and using the analytical-structural modeling (ISM) approach, which is one of the most widely used research methods in soft operations; We have leveled and modeled these factors to help policymakers and managers of the Islamic Republic of Iran in the fight against economic corruption as one of the main security threats to the Islamic Republic of Iran.The results of structural-interpretive modeling show the components of "instability in the country's economic system", "inefficiency of anti-corruption laws", "existence of monopolies in the economy" and "institutionalization of oil-based economy" in There are independent criteria that are the key factors influencing the formation of economic corruption in Iran.

War game is a method and a tool that enables commanders and managers to make optimal decisions. The role of playing war in different fields (military, economic, political, social and cultural, etc.) is to choose the best internal solutions against threats, or in other words, to make a good decision. The war game is a process with specific rules and steps that tries to visualize the flow of the mission of the internal forces and takes into account the capabilities, strengths and weaknesses and possible solutions of the internal force and the opponent or enemy in the form of action, reaction and counteraction. The war game is the most valuable stage of analysis and analysis of the solution in operational estimation. The wargaming process tests a strategy or modifies an established strategy. The aim and findings of this article is to present a process model of the war game in command and control and to create a standard method for unanimity in doing this. Undoubtedly, decision-making and planning, which are considered critical steps in command and control, will be effective and desirable when they use the war game method. The research method in this article was library and documentary study and using reliable scientific sources, the experiences of experts in this field through in-depth interviews.

New age wars have changed much, proportional with today's human life, and their complexity is far more than the past wars. The full spectrum operations, the latest US military doctrine, takes into account a very complex area of conflict by simultaneously applying all the economic, military, political, and social dimensions of the conflict environment. In this complex condition, it is vital for the commanders that having an evaluating and predicting the desired and undesired effects of each decision in operations and so take the correct and timely decisions. Modeling and simulations methods are very useful for solving this problem and simplfing decision making in complex conditions. But correct designing and application of this methods are not simple. The goal of this research, that type is applied research, is attention to utility of this ability in full spectrum operations conflict environment. biased on power structure modeling, in this research is proposed a quantitive model for evaluation of  U.S. full spectrum operations in Sadr city. By MATLAB software, computed model is simulated and  its efficiency has been investigated.

The application of mathematical science can be seen in all sciences. Military sciences are no exception to this, the use of mathematics in wars has a long history. From the parameters of the war, the rumor and publication that is posited as a weapon of psychological warfare, Islam is so important to the psychological security of the community that, in verse 60 of the surah al-Ahzāb, the decree dismissed those who were broadcast by rumors during the war between the people The Islamic State Islamic Center is creating insecurity. This paper presents a new model of rumor distribution. In this paper, by describing the rumor distribution model with the help of a differential equation system, we will analyze and analyze this model from the standpoint of dynamic systems, and divide the society into three distinct categories: ignorant, distribute and stop. By describing the system, we study the stability states of the system, then we can analyze the model under different conditions.
