Discovering the causes of aviation accidents and their prevention as well as solving aircraft design and construction defects are needed to prevent aviation accidents in the future. The present study aims to investigate the dynamics of the aviation accident management system in Iran and identify prevention policies.

In this study, a dynamic model for the aviation accident management system of Iran was designed based on the opinions of policy-makers and aviation experts. After validation, the model was simulated for a 20-year time horizon. According to the Monte Carlo sensitivity analysis results, the aviation accident prevention policies were identified based on three strategies: Development of the country’s aircraft fleet, standardization and improvement of flight safety, and development of pilots’ flight competencies. After applying the policies of each strategy separately on the tested model, the results were compared.

The identified policies included: 1. Financing and budget allocation for aircraft fleet development and purchasing new aircraft to reduce the obsolete fleet by 50% in 5 years, 2. Supporting the aircraft industries in the country and transferring advanced technologies to the country in contracts, 3.) Improving the standards of flight planning and existing aircraft, 4. Increasing the monitoring of flight planning implementation quality according to international standards, 5. Using the aircraft development financial resources for the development of flight safety equipment, 6. Investigating the causes of aviation accidents and implementing risk assessment tests according to national guidelines (CAD 1119), 7. Increasing the productivity of aviation higher education courses and improving the competences of pilots and 8. Increasing the monitoring of pilots’ physical and mental fitness for flight. 

The proposed dynamics model of the aviation accident management system in Iran is an efficient model according to the data of national and international civil aviation organizations.

The Islamic Republic of Iran, like other countries, has issues related to decisive and fateful choices that give direction to all the country's affairs and determine the task and direction of the system in the long term. The present article, with the aim of developing a model of strategic issue-finding in the Islamic Republic of Iran, seeks to find out the processes through which these issues are formed, constructed and addressed, and are included in the policy-making or decision-making agenda, and what factors cause the set of many and numerous issues facing the policy makers, some issues are taken care of and some issues are not paid attention to.

The type of present research is applied and its approach is mixed with descriptive-analytical method. The research data was collected by both library and field methods (semi-structured interview and questionnaire) and the information obtained in the qualitative part was analyzed by thematic analysis with the help of Maxqda software and in the quantitative part by the statistical analysis method with the help of SPSS software has been analyzed. The validity of the theme analysis was calculated by independent coding method and the reliability of the questionnaires was calculated with Cronbach's alpha. The statistical population in the interview section was 10 expert professors in the field of policy making and in the quantitative section, the questionnaires were distributed among 20 expert and educated people in related fields, and for sampling, the sampling method was used. It was used purposefully until reaching theoretical saturation.

The pattern of strategic problem-solving in the Islamic Republic of Iran is directly influenced by four basic environmental dimensions and its following components, which are: sources of creation and production of strategic problems, characteristics and dimensions of strategic problems, factors affecting strategic problem-solving and Criteria for strategic issues. Each of these environmental dimensions have components that are extracted and finalized after field investigations, which are discussed in the research model.

The process of strategic problem-finding is a cyclical process that starts from the latent period and ends with the ordering of problems, and with the implementation of strategic decisions or policies, it leads to the creation and production of new problems. Therefore, the problems are constantly growing and developing, and the more they grow, the more their complexity and interweaving with other problems will increase. Among the most important and effective factors in the strategic problem-solving model are the mental and perceptual frameworks that shape the strategic mentality of influential people, the rule of strategic thinking on the pillars of government, including the three powers, institutions, organizations, and political parties. Paying attention to the recognition of the common people and the interests of the common people, the influence of different social groups in the society on the bias of the opinions and decisions of policy makers, directing and managing the media and social networks, monitoring and scanning environmental developments in the Internally and externally (international) dimentions, the existence of strong and sufficient material and spiritual infrastructures. and values ​​and strategic goals governing the census system.

Regional justice, disenfranchisement and sustainable development and reducing the gap between the rich and the poor were among the ideals of the Islamic Revolution, which, despite significant progress, are still considered important issues in the society. Sustainable development is one of the most important strategies of the regional planning system, which has received much attention in recent decades. Sustainable regional development, considering access to natural resources, is proposed in the area of economic and social development of the region. So that the economic development of the region should remain at a level that does not exceed the environmental capacity of the region and lead to the improvement of the quality of human life. This research seeks to identify the sustainable development policies of the deprived areas of Delfan with regard to the available financial resources based on the dynamics of the regional sustainable development system.

This study is an application of system dynamics in sustainable development policies of deprived areas. The system dynamics (SD) is for the purpose of modeling complex systems in order to understand and recognize the situation of the problem for the policy makers and to test and ensure the effectiveness of the proposed policies. Therefore, this study has designed the dynamic model of the sustainable development system of deprived areas and simulated the development of the deprived area of Delfan in a ten-year horizon with the participation of regional development planners in order to identify deprivation policies.

After examining the issue of regional sustainable development and policies to reduce poverty in the deprived and less developed regions of the country, with the participation of the beneficiaries of Delfan regional development in Lorestan province, the issue of sustainable development of the deprived region in three economic subsystems and infrastructures sustainable development of deprived areas, social subsystem of sustainable development of deprived areas and environmental subsystem of sustainable development of deprived areas were identified. The economic subsystem and infrastructures of sustainable development of the deprived area deals with the financial flow of deprivation removal resources and its expenses in the infrastructures. The financial resources for the removal of deprivation in Delfan region, according to the financial resources available to the institution of deprivation removal, are government financial resources and the participation of private sector investors. In accordance with the situation of the deprived area of Delfan and considering the capacities of natural resources, economic investments and entrepreneurship were considered in three sectors of agricultural and animal husbandry entrepreneurship development, tourism service entrepreneurship development and mining entrepreneurship development. Considering the creation of job opportunities and employees in different sectors, the amount of household income and the amount of urban and rural poverty in the region were considered. The social subsystem of the sustainable development of the deprived area deals with the dynamics of the urban and rural population and migration and unemployment and the active workforce in the agriculture and animal husbandry sectors, tourism services and mines. The subsystem of natural resources and environment of the region focuses on the protection of lands, pastures and forests and water resources with regard to economic development. According to the subsystems of the model and the identified factors and relationships of each subsystem, the causal model was designed and the intensifying and moderating loops of the problem were explained.

According to the results of the sensitivity analysis of the model, economic sustainability strategies in the two policy categories of civil infrastructure development and investment in agriculture, tourism services and industry and mining; Social sustainability in four policy categories promotion of public awareness, entrepreneurship development, community-oriented empowerment and encouraging policies for entrepreneurship development and environmental sustainability in three policy categories of adherence to environmental requirements, sustainability of water resources and sustainability of soil resources was identified. In the following, by applying separate and combined strategies according to available financial resources; The behavior of model variables was investigated and compared. The implementation of selected policies shows that by spending financial resources of about 6 thousand billion rials in the region during three years by the institution of deprivation reduction and also the participation of the governorate and other executive bodies of Lorestan province in the development of the region's infrastructure and private sector participation in economic development investment; The increasing trend of urban and rural poverty will decrease after a five-year delay by preserving arable lands, pastures and forests, and the effects of poverty and deprivation will disappear permanently in the region. The proposed applied model of system dynamics in the policy of sustainable development of deprived resions and its efficiency is presented in the deprived resion of Delfan.

The growing concern about climate change has increased awareness about the essential role of forest ecosystems. About 36% of forest lands in the world have affected by forest fires. Fire affects the functioning of the ecosystem and forests and causes soil erosion and changes in the carbon cycle over the climate, vegetation and lands. This study aims to identify and analyze the policies for the management of man-made fires in the Zagros forests, with a focus on the causes of man-made forest fires (intentional or accidental)

Using the system dynamics approach, the model of forest fire management was designed in Vensim DSS software, version 6.4E with the participation of natural resources policy makers from the Lorestan province in Iran and the fire data of North Zagros forests. The model was simulated over a 20-year horizon. Based on the Monte Carlo sensitivity analysis. forest fire management policies were investigated based on three main strategies: Prevention of fire incidents in the forests and pastures of North Zagros, command and management of fire incidents in the forests and pastures of North Zagros, and reconstruction of the forests and pastures of North Zagros after the fire incident. Finally, by applying the policies, each strategy was tested separately on the model and the results were compared.

Based on the results of the model simulation, the propose policies included: 
1. Providing forest protection equipment, 2. Matching the number of rangers with the density of forests, 3. Specialized training for rescue and protection forces, 4. Raising public awareness about the consequences of forest damage using local and national media, 5. Supporting NGOs and training local volunteers to protect forests and pastures, 6. Developing incident command systems, 7. Developing a decision-support system based on knowledge management of forest fires, 8. Developing an incident command system for inter-organizational coordination at the time of fire incidents and 9. Investigating and analyzing the root causes of each fire incident.

The proposed model is an application of the system dynamics approach for developing policies of man-made forest fire management, validated based on the fire data of the North Zagros forests in Lorestan province.

One of the major challenges in the management of construction projects is the lack of understanding of the mechanisms that cause delays in construction. In the meantime, government infrastructure construction projects have a more complex situation, so that the success in the timely implementation of a construction project within the framework of government laws is one of the biggest goals and concerns of managers and agents involved in these types of projects.

It can be the present study identifies the mechanisms of project time delay risks based on system dynamics in order to identify and evaluate policies for the timely implementation of construction projects. For this purpose, first the literature and background were examined and during the semi-structured interview with the participants of the research, the effective factors on the timely implementation of the Iranian government construction project were identified. In the continuation of the dynamic model of the timely implementation of the Anrani project, the simulation was carried out using the data of the infrastructure operation project of the first section of Mobarakeh railway, Sefidasht, Shahrekord.

After validation; According to the results of the sensitivity analysis of the system dynamics model, the exploitation policies during the construction project were identified in three strategies of providing project financial resources, project planning and control, and accountability of the project beneficiaries. In the following, it was also designed and applied to the model with selected combined policies. comparing the behavior of key model
The combined selected policy

Crime investigation is a major concern for both governmental and non-governmental organizations, as well as judicial, security, and police systems in general. This necessitates the use of existing scientific potential as the primary tool for prevention and combating crime to reduce its occurrence as much as possible. In this regard, the main objective of this research is to design a strategic model for document forgery crime investigation with a police approach. This research employs a mixed-method (qualitative and quantitative) research design. The qualitative population includes informed experts on the subject, such as detectives, specialists, judges, professors, and experts (within and outside the organization). The sample size in the qualitative section was determined based on theoretical saturation. In the quantitative section, approximately 30 experts in document forgery from the Cyber Police and Tehran Greater Police Intelligence were estimated, and a complete enumeration was carried out. Semi-structured interviews were used for qualitative data collection, and a researcher-made questionnaire was used for quantitative data collection. Confirmatory factor analysis using SPSS version 21 and Lizerl software was employed for quantitative data analysis. According to the qualitative findings, four main dimensions (content, process, contextual, and functional) were categorized. In the quantitative section, using structural equation modeling, the results confirmed all the intended dimensions. In interpreting the research results, it should be noted that the content dimension in document forgery crime investigation is of special importance, and there is a perceived gap that, according to experts' opinions, laboratory equipment should be upgraded with technological advancements. Regarding the process dimension, there is a need for more coordination between the police and the judiciary; furthermore, utilizing a database with a focus on electronic governance is a turning point in combating document forgery in the contextual dimension. Finally, the functional aspect of document forgery crime investigation holds special importance.

The Islamic Republic of Iran, like other countries, has interests in the Southwest Asia region, which needs to increase its regional power in order to secure them. Considering that the meaning of regional power is the spatial concept of the national power of the Islamic Republic of Iran in the geopolitical region of Southwest Asia, which is the result of the potential and actual capabilities of the Islamic Republic of Iran, therefore, geopolitical factors can be defined as Consider the power booster.

The present article was written with the aim of explaining the strategies of promoting the regional power of the Islamic Republic of Iran based on the role of the socio-cultural geopolitical factor of Yemen. The current type of research is applied and its approach is mixed with descriptive-analytical method. The data were collected using both library and field methods (semi-structured interview, questionnaire and expert panel) and the obtained information was analyzed using the content analysis method with the help of MaxQDA software. Content validity and reliability of the interview were calculated using Cohen's kappa formula, and the reliability of the questionnaire was also calculated with Cronbach's alpha.

The findings of the research include the proposal of 3 basic strategies in order to promote the regional power of the Islamic Republic of Iran, which include helping to deepen the unity of the Zaydi groups and rapprochement with other religions in order to increase the power of the people at the core of the Yemeni resistance forces, help To develop the infrastructural capacities and capabilities (service, social and cultural) of Yemen in order to consolidate the historical, religious, social and cultural ties of this country with the Islamic Republic of Iran and to consolidate and deepen the unity of Ansarullah in the system of the Islamic Resistance Front.

Nation building in Yemen is the first step in forming a country that conforms to the standards of the Islamic revolution, and if this issue is not pursued, other emerging and deviant ideas such as Wahhabism and Takfiri will find a firm foothold among the Yemeni people and eventually will lead to the creation of a culture that fits these ideologies in Yemen.

In the present paper, a suitable framework for extracting or redefining the doctrine is presented. The doctrine determines the orientation of the individual / firm / organization in the face of strategic decisions; Hence, having a pattern for determining doctrine has a direct effect on making the right strategic decision. For this purpose, by conducting library research, concepts related to doctrine were collected and analyzed with an interpretive approach. Then the strategy of comparative analysis was used to extract the relationship between the concepts and the doctrine. According to the results of this research, doctrine is in fact the principles and requirements of the individual / firm / organization that are determined by focusing on the environment. The validation test of the extracted model was held in an expert working group with the presence of 120 experts and managers of strategic planning of industrial organizations After approval by the expert working group, the template was used to determine the doctrine in several strategic planning or decision-making projects (such as the Strategic Planning Project for Intelligent Road Transport). In all cases used, the designated doctrine had good accuracy and efficiency, which, in fact, shows the proper application of the template.

The main aim of this study is to reduce costs and improve the efficiency of the Tehran subway project. The approach to this research is a system engineering with life cycle methodology. Needs analysis is the first phase of the life cycle and the next phases are Design, production, operation, support, and retirement. Needs analysis, which is the first and most important phase of the life cycle, has been performed in this research. For this purpose, a questionnaire including 42 questions was distributed and collected from 220 customers of Tehran Subway. 10 factors that have more than 70% of the variance of customer needs were discovered through exploratory factor analysis and named subway quality indicators. In addition, 39 customer needs with specific values greater than one and operating loads greater than 0.5 were identified and selected as customer needs. Then, using the network analysis process method and the MATLAB software, the importance of each of the subway quality indicators and the importance of customer needs indicators was achieved. And finally graded. Based on the findings of this study, in the implementation of the design phase of the Tehran subway life cycle, all 10 indicators of subway quality should be considered, but the availability of vehicles and station facilities need more attention. Also, all 39 subway customers need indicators that should be considered in the design, but the top 10 requirements indicators are much more important than the other 29 indicators.

In conducting the criminalization process, judicial officers face the challenge of observing the civil rights of the accused and establishing security order. This study has been compiled with the aim of identifying the challenges of the civil rights of the accused in the criminalization process.

The present research is applied in terms of type and purpose and descriptive-analytical in terms of method and qualitative in terms of the nature of the data. The second range includes the statistical population of 114 people, which consists of heads and deputies of all eleven intelligence bases in Greater Tehran and first-level deputies of the NAJA Awareness and Prevention Police Managers, 72 of whom were used as a purposeful sample.

The research findings indicate that the most challenges are related to the judicial process, including lack of immediate access to judicial authorities and lack of legal and appropriate protection of judicial officers, and the least challenges are related to the management process, including lack of facilities and equipment And failure to provide technical and specialized training for the discovery of the grain to the judicial officers.

The challenges are mainly related to the arrest phase and under police supervision, 107 initial codes and 58 sub-themes were identified, which were analyzed in the form of 4 main themes (legal, judicial, police executive, NAJA management). It seems that the best way to observe the citizenship rights of the accused is to obtain the necessary specialized and technical training in the field of crime detection and crime detection by resorting to the techniques of studying legal and legitimate evidence to resolve current legal ambiguities and maintain judicial interactions, especially in crimes.
