Earthquakes as one of the most important natural disasters on earth, have always caused irreparable damage to human settlements in a short period of time. Severe earthquakes have led to the idea of developing an infrastructure plan to reduce the risks and damages caused by it. The urban water supply system is the most important critical infrastructure that is usually damaged by natural disasters, particularly earthquakes and floods; hence, the function of the pipelines of the water system determines the degree of resilience and design of the infrastructure against multiple natural and man-made hazards. Considering the inability to prevent earthquakes and the inability of experts to accurately predict the time it is necessary to know the status of earthquake-structure and seismicity in Tehran to determine the amount of earthquake risk in order to make the necessary planning for structural reinforcement. Theoretical and field studies of tectonic seismicity in the Tehran area show that this city is located on an earthquake-prone area around the active and important faults of Masha, north of Tehran, Rey and Kahrizak. The occurrence of 20 relatively severe earthquakes illustrates this claim. Regarding the location of faults in Tehran city, it is necessary to assess the vulnerability of Tehran water facilities.

The present study is a practical-analytic one. Considering the severity of earthquake damages, it is necessary to conduct earthquake hazard zonation studies in different urban areas and to determine important indicators of damage assessment such as maximum ground acceleration, maximum ground speed, maximum ground displacement. Three indices were considered for mapping earthquake seismic zones and their integration into the GIS presented a seismic hazard map. In the analysis of earthquake risk, it is necessary to evaluate two indicators of risk and vulnerability. To prepare the general hazard power mapping the weights obtained from the ANP model were applied to the existing raster layers via the Raster Calculator command. In this way, the standardized layers are multiplied separately by their respective weights and finally overlapped. In order to evaluate the vulnerability, a series of evaluation indices are introduced and ANP techniques are used. The relative value of each index is then calculated using the multivariate approach using the SAW technique. In order to calculate the earthquake risk based on R = H * V relation, the values ​​of these two components were multiplied. This calculation was performed in GIS software on the risk and vulnerability raster layer and the final result of this calculation was displayed on the map.

In this study, we tried to estimate the relative risk and risk of seismic hazard on the water supply lines in Tehran, using available data and scientific methods, and map the risk level. These lines should be prepared first by the amount of earthquake hazard risk and then by the risk map, to estimate the earthquake risk on the water supply network. first the earthquake risk then the status of the hazard lines should be calculated. The vulnerability of the water supply lines was calculated using the ANP model by multiplying the total potential hazard risk then substrate transfer network vulnerability risk map obtained transmission network. The highest risk was in the west and north of Tehran. The maps showed the risk potential and the vulnerability of the lines. These areas had high seismic potential and the density of the lines was higher in these areas. Water transmission facilities are at risk and earthquake hazards may be affected by damage to the transmission lines, drinking water to a large population will be difficult, as well as performing necessary zoning to prevent future expansion of the facility in place. These analyzes are a prelude to applying corrective techniques to pipelines to reduce their vulnerability and prevent newly created pipelines from locating in vulnerable areas. Since the results of this study are risk maps along the route of the water supply lines, so in order to prepare a risk control program, we can identify the high risk pipeline map and identify the pipeline vulnerability. And, depending on its location, provided an appropriate prevention and control plan for the conditions surrounding the pipeline environment.

One of the main necessities of the growth and development of any society is the constant attention to the subject of transformation, in which Imam Khamenei (Supreme Court) has explained the concept and framework of the proper transformation in numerous statements and speeches. The purpose of this study is to identify and explain the dimensions and components of transformation-demanding and transformation-creation from Imam Khamenei's perspective.

In terms of research philosophy, this study is an interpretive research, and in terms of its objectives, it is considered an exploratory research. The research strategy is qualitative that was conducted using content analysis method. Ultimately, the data collection has been a library study with a note-taking tool and reference to original sources. Its statistical population is the sum of the statements of Imam Khamenei from 1989 to 2021 on research issues.

By examining and analyzing the data, the three themes of what, why, and how were classified in comprehensive themes level. In the "what" of transformation, the components of "the definition of transformation and its equivalent, the goals of transformation, the principles and principles of transformation, the level and scope of transformation, the examples of good transformation, the examples of bad transformation" were identified. In the "why", the components of "need and necessity of transformation, the must and shoulds of transformation", and in "how" of the transformation, the components of "major requirements and measures for the implementation and implementation of transformation, speed and direction of transformation and some areas of transformation" were obtained. In the implementation and naming of themes, the MAXQDA software has been used. For drawing the themes network the XMind Map software was employed. The ultimate model of transformation can take an effective step in understanding the real transformation creators and transformation demands in the country.

 

According to upstream documents, universities should always be the boiling point and peak of two vital currents in the country: the flow of science and research; Second, the flow of idealism and idealism and political and social goals; And since today's universities face many challenges such as turbulent environment, rapid growth of global competition, changing knowledge and industrial needs of society, etc., so by examining and analyzing the paths taken, we must recognize the strategic deviations of the path. And with the right look, he proceeded to reform and improve effectively for the development and promotion of universities and, of course, the country. The important point is that the main purpose of designing the strategic control system of universities is something beyond compiling several annual evaluation reports in a scattered manner. Strategic control is a system that organizations need to be aware of changes in the internal and external environment as well as respond to these changes, and by strategic control and careful review of the strategic direction of the organization, can make changes in a timely manner. In this regard, the concept of strategic control has an effective role in guiding universities in the direction of their strategic goals. The purpose of this study is to identify the components of strategic control in universities studied by one of the universities in Tehran province.

 The present research is applied in terms of purpose and descriptive-survey method. The method of data collection in the stage of identifying the components of strategic control affecting the university is in the form of library studies and interviews with professors and experts. In this research, the MICMAC table has been used to analyze the degree of penetration and dependence of each factor. Interpretive structural modeling (ISM) has been used in the implementation and analysis. Interpretive structural modeling is a method for designing a pattern of complex and multiple relationships between variables of a phenomenon. This method is a kind of structural analysis based on the interpretive paradigm. In this method, first the effective and basic factors are identified and then with the help of this method, the relationships between the factors are analyzed. This model provides a context in which various and interrelated factors are described in an organized model and a complex pattern of conceptual relationships between several variables. The statistical population of this study was university professors, experts and related university administrators who were selected by purposive sampling. Therefore, the statistical sample method of this research is purposeful sampling of a judgmental type that consists of 10 university professors, experts and managers related to the subject of strategic control. Regarding the expertise and background of the sample, all of them have a doctoral degree and at least 5 years of work experience related to the research topic, whose opinions have been recorded and compiled by the researcher.

Regarding research results and findings, the policy-making and management component has been identified as the most fundamental and fundamental component. It can be stated that the component of policy-making and management with the highest influence and the least degree of dependence on the components of human capital, budget and finance, values ​​and organizational culture, networking and interactions, facilities and facilities and finally the exchange of knowledge, research system and The education system is effective. The third level includes two components of values ​​and organizational culture and networking and interactions that affect the next level, namely the components of human capital, facilities and facilities, budget and finance, research and production system, knowledge exchange and dissemination and education system. In other words, the components of policy and management, values ​​and organizational culture, and networking and interactions in the MICMAC table are in area 4 and have high influence and low dependency; This shows the importance and impact of these factors on other factors. At the second level, the factors of human capital, facilities and facilities, budget and finance are all at the same level and affect the factors of the next level; Finally, in the first level, which has the most dependent factors, are the system of research and production of science, exchange and dissemination of knowledge, and the system of education and training.
 

In other words, in order to have a proper research and production system and a proper education system, the lower level components must act in a systematic and coordinated manner so that the output of research and education is also appropriate.

Expert knowledge management for reuse is always considered by researchers. The present study identifies the dimensions and components affecting knowledge management using fuzzy cognitive mapping method. In existing researches, many methods have been proposed to identify the factors affecting knowledge management, and have been developed in accordance with the specific environmental conditions and the type of knowledge in question. Despite extensive research and numerous knowledge management projects, identifying these factors in organizations has always faced many challenges. What is important in this article is to solve the problem of knowledge management through fuzzy cognitive mapping in Iranian organizations and especially in the Hajj and Pilgrimage Organization. For data collection, the method of expert meetings and the formation of a focus group with the presence of 8 experts in the field of knowledge and knowledge management was used and using previous research, a total of 9 factors were identified; The importance of each of these components was determined using FCMaper software and its fuzzy perceptual mapping pattern map was drawn using Pajek software. The results showed that among the 9 components, "joint venture" and "cooperation" were in a higher degree of importance than other factors.

The purpose of this study is to provide a comprehensive model of the characteristics of jihadi management in commanders of eight years of holy defense. To write the research literature, the method of library studies has been used and to achieve the main purpose of the article, the method of content analysis or theme with an interpretive approach has been used. For this purpose, the statements of Imam Khomeini (RA) during the years 1359-1368 and the statements of Imam Khamenei (as) during the years 1399-1360 have been studied. Due to the high volume of lectures, more than 90 lectures related to the research topic were analyzed by purposeful selection and study. In order to analyze the text of the lectures, after carefully studying these texts and creating the initial codes, the sub-themes were identified and refined, and then the themes were extracted by classifying the identified sub-themes. X-Mind Map software has been used to draw the network of themes. In total, 189 concept codes (in the form of 128 concepts), 55 sub-themes and 13 main themes were obtained from the studies. The thirteen main themes of this research are: self-sacrifice, struggle, God-centeredness, insight, creativity and innovation, morale Self-confidence, biological simplicity, service spirit, duty-oriented, conscious and compassionate management and guidance, staffing, honesty, justice.

Having an accurate knowledge of the enemy, its methods of hostility and procedures contain the most important tasks of analysts and defense-security policymakers of the country. Hence, in order to identify the methods of assessing the enemies, this study tries to investigate the pure evaluation as a model for defense-security assessment. This study is also intended to fill the important literature gap in this field by presenting the main concepts of pure assessment and give a history of studying this method for analysts and policymakers. Pure assessment is a method of strategic evaluation and analysis in the United States, Britain and the occupying regime of Israel, having been founded in the United States about half a century ago. This developmental research follows descriptive-explanatory case study method. For collecting research data, the method of library and documentary studies has been employed. The results revealed that using pure assessment brings about a systematic and holistic view for defense and security and level assessments as well as a long-term and forward-looking approach to issues concentrating on assessments on the basis of quantitative-qualitative consideration, rather than focusing solely on quantitative issues. This method of assessment provides an appropriate and methodical framework for analysts and policymakers by analyzing complex and comprehensive political, economic, social, and military relationships.

Since the goal of today's management and its success criterion is to help achieve the vision, goals, strategies and continuous improvement of organizational performance and one of the most important steps for organizational success in the field of performance, comprehensive and strategic view of management Performance in the organization. Also, a system of evaluation and monitoring in the form of performance management that monitors the macro plans of the camp with a systematic view at all levels and from the feedback received not only for evaluation, but with the aim of continuously improving it and achieving strategic goals and plans. It is one of the necessities. The main purpose of this article is to Designing a Strategic Performance Management Model in Large Engineering Organizations (Case Study: Khatam-al Anbiya Construction Headquarters) in order to benefit from it.  

This article is descriptive-survey in terms of practical purpose and in terms of type and method of data collection. In order to collect information on the factors affecting strategic performance management, theoretical-field studies have been conducted. After reviewing the research background, a Delphi panel was formed and appropriate members were selected for it. Judicial sampling method has been used in selecting panel members; Two groups were selected. The first group of experts familiar with the camp and the second group of experts in the field of performance management in the organization. 25 people from the first group and 15 people from the second group announced their readiness, which formed a panel of 40 people in total. Finally, after three rounds of implementation, a consensus was reached on the factors affecting the management of strategic performance; The identified factors were the basis for preparing the ISM questionnaire. At this stage, 25 managers and experts were identified to determine the type of relationship and prioritization of factors and this questionnaire was used to determine the final pattern. In this research, due to the high complexity of the systems and multilayer units of the relevant organization, by no means, it is not possible to be satisfied with just using one method (quantitative or qualitative) and with it, gain sufficient knowledge about the research situation. For this reason, in order to meet this need, a combination of quantitative and qualitative methods, called combined or mixed research methods, the combined exploratory method has been used and the approach of this research is inductive-deductive. In terms of strategy, this research uses content analysis and typology strategies, and finally, the method of data collection is document review and questionnaire.  

In this study, the factors affecting the strategic performance management of Khatam-al Anbiya Construction Headquarters construction camp were identified by Delphi method. The 14 factors affecting the strategic performance management of the construction camp include the following: Strategic goals taking into account stakeholders; Define the expected level; Strategic control; Performance measurement; Continuous performance feedback; Reporting and disseminating information; Performance review and correction; Key success factors and selection of key metrics and indicators; Operational control; Organizational Structure; Collection and flow of information; Pivotal action plan; Conceptual exploration and environmental exploration.

Based on the final diagram of the ISM model, the strategic goals factor, considering the stakeholders, as the underlying factor affecting the strategic performance management is in the highest priority over other factors. This factor includes many factors that the mission and purpose of the organization; Micro and macro goals of the organization; Core values ​​and culture of the organization; Internal strengths and weaknesses of the organization; Opportunities and environmental threats of the organization are among these factors that the placement of this factor in the highest priority, shows the importance and comprehensiveness of this factor and the accuracy of the designed model. At the next levels, there are two factors: conceptual exploration (mission, vision, resources and values) and environmental exploration (strengths and weaknesses, opportunities and environmental threats); According to the majority of experts, these two factors support the strategic goals, which was also correctly obtained in the diagram. The level after the conceptual and environmental exploration is strategic control. In fact, strategic control by considering internal and external issues (from the outputs of conceptual and environmental exploration) always monitors strategic goals and, if necessary, modifies them according to the circumstances. The construction site is a military organization and has a hierarchy, so if there is a need for reform in the organization, it is necessary to make that change in the structure of the base (both organizational structure and information structure), which is clearly indicated in the diagram. Is. Now, it is time to plan the action and determine the key factors for success and select the key indicators that these two factors are correctly listed one after the other in the ISM diagram. In fact, although appropriate goals are set in any organization, but not implemented in the organization will not be of much value. In this regard, it is necessary to determine the key factors of success of the organization and its indicators, based on the strategic goals of the organization. The next step (data collection and dissemination factor) is to ensure its implementation. In the next level, two factors of reporting and disseminating information and collecting and flowing information that are bilaterally obtained are obtained, and in the last level, completely related factors such as defining the expected level; Performance measurement; Continuous performance feedback; Performance review and operational control achieved.

The purpose of this study is to investigate the effect of commanders' leadership styles on the effectiveness of the activities of the city's resistance bases. The research method is "descriptive-survey" and has been done by field method. The statistical population of this study is the Basijis related to the resistance bases of the city, which includes the commanders and managers of the bases and the commanders and managers of the resistance areas and other Basijis including 2369 people. Cluster sampling was considered and 10 people from each base were considered and a total of 494 samples were analyzed for research. The research measurement tools are the standard leadership style questionnaire and the researcher-made questionnaire on the effectiveness of resistance bases. The validity of the questionnaires was confirmed by university professors and experts and the reliability of the effectiveness questionnaire was confirmed by Cronbach's alpha with a value of 0.95. Data were analyzed by SPSS software, Kolmogorov-Smirnov tests, Spearman correlation coefficient and regression analysis. Among the studied styles, the effect of compassionate, counseling and participatory leadership styles on significant and positive effectiveness and authoritarian style are significant and negative. The results of this study showed that the highest effectiveness among the bases is related to the bases that use the participatory leadership style.
