This study examines the effect of energy price changes on the intensity of energy consumption in mineral products using a dynamic computable general equilibrium (DCGE) model with calibrated data, to simulate two scenarios (1.%5 price shock to natural gas 2.%5 oil price shock) until the time horizon of 2050, for three groups of regions and countries (Iran, Major trading partners, Rest of World) has been investigated. The simulation results of the DCGE model for Iran in the first scenario suggest a continuous improvement in energy efficiency, where the energy intensity values remain negative in general, the second scenario depicts a temporary increase in energy intensity for Iran, followed by a gradual decrease. which shows the increase in the energy sector of mineral products in the near future. Trade partners and other regions show a sharper reduction in energy intensity under the second scenario with faster rates of decline and more ambitious targets for energy efficiency. Based on the obtained results, it can be said that Iran is becoming more efficient in terms of energy consumption for the production of mineral products, which can be caused by various factors such as technological advances, improvement of production processes be which is running.

This study with the approach of combining macroeconomic growth with transportation supply and demand, investigates the role of transportation types on Iran's economic growth between 1380-1400, using the simultaneous equation system (3SLS) method. The results of the research showed that all three types of transportation (land, air and sea) have a positive and significant effect on economic growth, so that with a one percent increase in the value of the infrastructure of the transportation sector, economic growth increases by 2.10 percent. Ground transportation has the greatest effect on the growth rate with a coefficient of 0.783, because ground transportation is the main method of transporting goods and services within a country. Maritime transportation with a coefficient of 0.571 is an important factor in economic growth, because it plays an important role in international trade, and the volume of exports and imports by ports and ships can significantly affect the rate of economic growth. Air transportation has a relatively lesser effect on economic growth with a coefficient of 0.037, but it is an important factor in economic growth because it facilitates the movement of people and goods over long distances and leads to increased productivity and economic growth. Also, the price of transportation services has a positive relationship with the supply of transportation services, the population and the amount of income have a positive and significant relationship with the demand for transportation services. The relationship between the price of fuel and the government budget deficit with the supply of transportation services is negative, and the relationship between the amount of cargo transported and passengers moved and the demand for transportation services is positive and significant. The main recommendation of the study is the expansion of investment in road and rail corridors in the south-north and west-east (Silk Road).

Ardabil province has a very convenient geographical location, as a border province, for trade with neighboring countries. By improving the level of economic interactions with neighboring countries, we can benefit from the significant capacities that exist in this area. By providing special facilities for export and import neighboring countries, developing non-oil exports, creating tourism facilities, developing tourism services and appropriate advertising, attracting investment in transformation and complementary industries, it is possible to develop economic interactions with neighboring countries and expand commercial relations. The export amount of Ardabil in 1400 was 516 million dollars, the volume of trade between Ardabil province and Azerbaijan was more than 1.3 billion , the non-oil exports of Ardabil to neighboring countries were more than 64 million , the production of transformation and complementary industries in Ardabil was More than 2.4 billion have been collected and more than 105 thousand tourists from neighboring countries have traveled to Ardabil province, as well as the export of various goods and products from the customs of Ardabil province in the first seven months of 1402 to Azerbaijan 39 million, to Armenia 172 thousand And Turkey has 12,000, which has had a leaping and growing trend, which shows the importance of developing trade with neighboring countries. To develop economic interactions between the two countries, solutions such as export and import development, infrastructure, transportation, tourism promotion, cross-border cooperation, etc. can be used. Considering the positive signs that exist in the field of economic interactions with neighboring countries in Ardabil province, it can be concluded that the development and deepening of economic interactions of Ardabil province with neighboring countries, including Azerbaijan, Armenia, Turkey and the Republic Nakhchivan, can have a significant yield.this development can be considered as one of the main ways for economic development and increasing economic growth in Ardabil .

The aim of the current research is to investigate the relationship between monetary policy and Fisher's theory in Iran's economy using seasonal data during the period of 1370-1400 based on the structural vector autoregression (SVAR) model using the variables of monetary policy, interest rate, inflation rate, unemployment rate and production. GDP has been estimated by the model. According to the results obtained from the variables of the current research, no significant relationship has been obtained between the monetary impulse and the interest rate in the long term, either in a positive or negative direction, the result obtained with Fisher's rule that between inflation and the real interest rate in In the long term, there is no relationship, it is aligned and in the same direction, so it can be said that in the long term, Fisher's rule is valid in Iran. Based on the results of the research, it is suggested that politicians should avoid monetary policy with the aim of influencing the interest rate and increasing production. Also, the central bank policymakers should create a logical balance between the real interest rate and economic growth by bringing the interest rate of the facilities granted to different sectors closer to each other and reducing the interest rate of the commercial sector

The purpose of this study was to investigate the effectiveness of verbal creativity storytelling and phonological awareness of dyslexic students which was done by a quasi-experimental design with pretest-posttest with control group. The sample included 28 dyslexic male students who completed the third elementary school in the academic year of 2018 selected through convenient sampling from the centers of diagnosis and treatment of state and private learning disorders in the cities of Tehran, Shahryar and Karaj. The students were randomly assigned into two experimental and control groups of 14 people. The instruments used in this research were Dastjerdi and Solaymani Phonological awareness and Torrance Creativity Test of Verbal Section (Form A). The data were analyzed using covariance analysis. The results indicated that the method of storytelling was based on the overall score of verbal creativity, the score of each of the subscales (originality, fluency and flexibility), the overall score of phonological awareness, and the score of its levels (syllabic, intra-syllabic and phonological awareness). These have been effective and led to higher scores. Based on the findings of the study, the storytelling method is effective in improving the performance of dyslexic students.

Tourism is recognized as the world's largest service industry in terms of revenue generation. The development of this industry is particularly important for developing countries, which are faced with many problems, including high unemployment, limited currency reserves and a single-product economy. The main purpose of the present research is to investigate the effect of exchange rate fluctuations on the tourism sector of Iran. For this purpose, first, using the official exchange rate data, we obtained exchange rate fluctuations through ARCH / GARCH model variance models, and then with work The using of ARDL distortion self-oscillation pattern model has been used to estimate long-term and short-run relationships between research variables during the years 1360-1394. The results of the estimation of the study show that there is a significant and negative correlation between exchange rate fluctuations and incoming tourists to Iran, and there is a positive and significant relationship between exchange rate fluctuations and gross domestic product and consumer price index.
