Recurrent aphthous stomatitis or RAS is one of the most common lesions of the oral mucosa, which is recurrent and painful. So far, several factors have been known as predisposing factors to this disease. However, there is no specific treatment for it. Anxiety and stress are among the causes of these lesions. Quality of life reflects the level of satisfaction and sense of well-being in individuals. Since it is believed that these lesions affect the quality of life due to their chronic and painful nature, the present study aimed to evaluate the quality of life of patients with recurrent oral aphthous stomatitis using the COMDQ questionnaire.

The tool used to measure quality of life in this study was the COMDQ questionnaire. This questionnaire examines the quality of life of patients with chronic mucosal diseases using 26 questions in four subgroups, including pain and functional limitations, treatment and medication, psychological and social status, and patient support. In the scoring system for recurrent aphthous stomatitis, the characteristics of lesions in the last three months and factors such as the number of lesions, the rate of recurrence of lesions, and the affected areas should be considered to determine the severity of the disease. Thus, the USS system, which is derived from the combination of the above items, was used. The USS system includes 6 subgroups, including the frequency of the aphthous lesions in the last three months, diameter, duration, ulcer-free period, location of aphthous lesions, and pain. Pearson's correlation coefficient was used to calculate the correlation between age severity and duration of the disease with quality of life. To compare the average scores of this questionnaire in two genders, an independent t-test was used, and the Mann-Whitney test was used if the data were not normal. Data analysis was done by SPSS ver 25 software.

In this study, 251 questionnaires were completed using the census sampling method. Among the study participants, 116 (46.22%) were men and 135 (53.78%) were women. The average total COMDQ score was 43.34±13.78 and no significant difference was observed between men and women in any of the dimensions of quality of life and the total quality of life score, as well as age (P>0.05). The correlation between COMDQ total score and general health (P=0.014) and also in comparison with oral health was significant (P=0.014). Also, the severity of lesions (USS score) (P<0.001), the number of aphthous ulcers in the last three months (P<0.001), duration (P<0.001), ulcer-free period (P<0.001) and a lower score in the subgroup of the location of oral ulcers (P=0.033), there was a significant relationship with the total score of the quality of life questionnaire.

Lesions of recurrent aphthous stomatitis are painful and have a long treatment period. In addition, various factors contribute to the occurrence of these lesions, and patients often suffer from them. Therefore, these lesions bother the patients and according to the results of the present study, they affect the quality of life of the patients. Raising awareness about the nature of these lesions and their follow-up should be on the agenda. Also, the mental and psychological aspects of the health of the patients should be taken into consideration in the treatment approaches.

Population growth and industrialization have led to an increase in waste and sewage production, which is always a concern for urban managers. With the increasing population, in addition to increased waste production, the need for energy also increases. With the increase in energy consumption, a renewable source must be sought to meet the country's needs. Municipal solid waste and sewage sludge have a high potential for energy production due to the high volume of organic matter in them. Therefore, in addition to waste disposal, appropriate management of waste and sewage can be used as a suitable source of energy production. In this research, simultaneous management of sewage and solid waste in Tehran was carried out. For this purpose, information was implemented on a superstructural model, and then, using Python programming language and decision nodes, decision coefficients from 0 to 100 percent with a one percent step were considered. Finally, 592 scenarios were proposed, and two scenarios were selected as the best scenarios in terms of energy perspective, with the approaches of heat recovery and electricity production. In these two scenarios, approximately two million gigajoules and one million four hundred thousand gigajoules were recovered as the highest heat and electricity from simultaneous management of sewage and solid waste in Tehran city, respectively. By implementing this model for Tehran, urban managers can use waste and sewage as a source to meet the energy needs of waste disposal systems and supply part of the city's energy needs.

Reducing the costs of maintenance and compliance and providing assurance about the ownership of assets is one of the achievements of blockchain technology in the accounting industry. The convergence of accounting and blockchain can create a new and intelligent accounting information system. Therefore, the purpose of the research is to design an accounting information system model based on blockchain architecture using a qualitative method and theme analysis using semi-structured interviews with experts in the field of information technology and accounting including 19 people and reviewing related researches. The present composition and pattern was designed. Based on this, by analyzing the content of the interviews and researches using 2020 MaxQda software, the relevant dimensions and codes were extracted and the importance and priority of each was determined using Shannon's entropy technique. Based on this, 3 categories, 40 concepts and 126 codes were extracted.Codes for guaranteeing commitments, improving security operation center measures and permanent access have the highest coefficients of importance in causal factors, conflict with existing platforms, scalability and lack of talent treasury in the field of interfering factors, improving data security, record security and Digital identity management was introduced in the results section with the highest coefficient of importance. Since a comprehensive model for the accounting information system based on blockchain architecture has not been presented so far, this research can be useful in the direction of emerging challenges, profitability and improving productivity in audit institutions

One of the ways to deal with social crises is to use the capacity of social media because media organizations spread messages that influence society's culture, which makes these mass media part of the fundamental and institutional forces. Society transforms. The purpose of this research is to investigate the role of social media in promoting the culture of altruism in the face of social crises.

The research method was qualitative content analysis. The statistical population of the research included all media experts and professors of social communication sciences and social sciences in Tehran city. Non-random purposeful sampling method was used for sampling. The data collection tool was a deep semi-structured interview and the data analysis method was thematic analysis.

The findings showed that according to the participants, social media has 6 roles in promoting the culture of self-sacrifice in social crises, and these 6 roles, in order of priority, are: 1. Accompanying and shaping public opinion, 2. Prominent Building, 3. Informing and raising awareness, 4. Education and culture building, 5. Creating solidarity and solidarity, and 6. Planning and organizing. Also, for each basic category, several subcategories were also identified.

The results of the research showed that social media played a role in promoting the culture of altruism and therefore have a suitable capacity to promote the culture of altruism in social crises.

The main goal of this research is to investigate the effect of auditor's moral principles and religiosity on the quality of independent auditors' audit services. The final sample used for this study includes 250 questionnaires collected from auditors working in auditing organizations and other auditing institutions. In order to collect information, the Armega Zarfar (2015) questionnaire was used, and descriptive statistics and the reflective model of structural equations based on variance were used to process the data. The findings of the research show that the variable of ethical principles and religiosity of auditors has a significant effect on the quality of independent auditors' audit services and leads to an increase in audit quality. Strengthening religious attitudes can be a protective factor against abuses and frauds, improving the health of financial reporting and the confidence of creditors, shareholders and other users of financial statements. Considering the importance of ethics, it is suggested to the community of certified accountants to consider ethics education in their training programs and to monitor the observance of professional ethics in order to improve the level of professional ethics of auditors.

The Social Security Administration is the most important lever for establishing social justice in civil societies. The demographic and diversity of the organization's activities exposes it to a variety of crises. Therefore, the present study was conducted with the aim of presenting an organizational leadership model in crisis management of the Social Security Organization of Iran.

The type of this research was qualitative and was done using data-based method. In order to achieve the organizational leadership model, eleven professors, experienced people in the field of the Social Security Organization were interviewed with in-depth semi-structured way, using targeted sampling method and due to theoretical saturation. Then the resulting data were interpreted through coding.

Research findings show that organization play three main service functions for crisis management in the Social Security Organization. The first function, which is detected in this study, is providing mediating factors of predicting and resolving the crisis. Mediating factors formulated through categories like; review on country's insurance laws, performing parametric corrections and developing protection laws. Finally, the third essential component of the organizational leadership model is management stability, financial stability and increasing social trust.

Achieving a crisis management model requires providing the ground, the existence of causal conditions, the existence of facilitator components and the use of appropriate strategies. The function of leadership is precisely in this area. Providing growth and development of the broker alone is not desirable and does not achieve crisis resolution and forecasting.

Today, the compression of the klystron tube is one of the most important topics for accelerators, along with high output power and efficiency. Multi-beam klystrons have the ability to generate high output power, with lower working voltage and interaction length of the wavelength with the beam than single-beam klystrons, and as a result, they will have less volume and weight. In this paper, the design and simulation of the wave-beam interaction region for a 40-beam klystron tube in S-band has been done using the second harmonic method, and the increase in efficiency has been introduced for the first time by the design method with a clustered cavity. According to the results of design, simulation and then optimization by local method, the output power of 15MW has been achieved in the interaction length of 238.8mm for the working frequency of 2856MHz and the input power of 13W. The efficiency and gain of the structure are equal to 76% and 60.66 dB, respectively.

A wood-wool cement panel (WWCP) is wood wool combined with Portland cement mortar. This environmentally friendly acoustic material can be used as a thermal insulator and fire-resistance material with desired mechanical properties. This study aimed to determine the mechanism by which WWCP absorbs sound and the effect of production and application parameters on absorption

The samples were prepared from poplar wood wool and white Portland cement as a binder in two Cement Fiber Ratios (CFR), namely 2:0.7 and 2:0.95, with bulk densities of 400, 500, and 600 Kg/m3 and thicknesses of 2 and 4 cm. Three layers of backing: air, polyurethane foam, and glass wool were examined separately. Acoustic absorption coefficient was measured using an impedance tube based on ISO 10534-2.

The highest increase in the average absorption coefficient due to the increase in thickness was observed for the sample with a density of 400 kg/m3 and CFR = 2: 0.95, equal to 0.3. Increasing the bulk density to 500 kg/m3 for most samples and in the high-frequency range led to rising absorption efficiency. The optimal backing effect was due to the placement of 4 cm of polyurethane foam behind the sample, which in both thicknesses led to an absorption peak with an absorption coefficient higher than 0.95 at frequencies between 400 and 500 Hz. Selected samples showed that painting WWCPs led to a limited drop in absorption coefficients at high frequencies, comparing the before and after painting results with oil-based paints.

Tuning the absorption frequencies of these absorbers can be achieved by altering factors such as the thickness or density. It has been demonstrated that the effects of thickness and bulk density on the sound absorption of WWCP are related to each other. Concerning the CFR values, increasing the density did not significantly affect absorption in the two frequency ranges.

The purpose of the current research was to reconstruct the narratives and experiences of teenagers in order to identify the duality of identity in the virtual and real space. The research method was qualitative and reconstruction type, which was conducted with interview participants. The statistical population of the research was all secondary school students of Ardabil province. The sample size included 16 students who were selected by purposive sampling and based on the principle of theoretical saturation. Semi-structured and in-depth narrative interviews were used to collect data, and for its reliability, the method of re-reading the narratives and re-referring the entire written narrative to some school counselors was used. The data was analyzed based on thematic analysis. The results of reconstructing the narratives of teenagers showed that real and virtual space has led to the formation of different and sometimes dual identities in teenagers. This identity duality can be seen in religious, family, sexual, national, ethnic and cultural dimensions. The identity of teenagers in the real space was more formed, coherent and real, and in the virtual space, it was relatively mobile, unstable and numerous. An identity which, according to some features, can be called a modern or re-thinking identity. In addition to trying to protect traditional sources of identity in the real world, teenagers showed themselves to be in favor of a global or cosmopolitan identity in cyberspace.

This research was done with the purpose of the role of the national media in realizing the goals of the declaration of the second step of the Islamic revolution (Purpose). The research method is applied in terms of achieving the goal and survey in terms of data collection. The statistical population of the research included all experts in the field of communication and media sciences. The sample size According to Morgan table included 150 experts, professors and experts in the field of communication and media sciences, who were selected using Available sampling method (Method). The tool used was a researcher-made questionnaire, which was derived from the three general indicators of the statement of the second step of the revolution (achievements of the Islamic Republic, strategic fruits of the revolution, and mission recommendations of the revolution). After collecting the data from the samples, it was entered into SPSS software and analyzed through t-test. The findings of the research showed that the national media played an favorable role in realizing the objectives of the second step statement of the revolution (finding). Also, the results showed that the media in realizing the achievements of the Islamic Republic of Iran (3.45±0.904), the strategic fruits of the revolution (3.37±0.889) and also the mission recommendations of the revolution (3.23±0.795),

This research was conducted with the aim of synthesizing foreign research conducted in the period of 2020 to 2023 regarding fake news. The sample size was determined based on theoretical sampling, 14 articles and according to information saturation. To analyze the data according to the main problem of the research, thematic coding method was used, which was presented in three stages: "open coding", "descriptive categories" and "analytical themes". The research results from the research synthesis have led to the identification of three main themes of "online environmental factors", "personal-social motivations of the user" and "fake news content" among the most important reasons for the tendency and dissemination of fake news in social media. The most important factor and driver of the fake news cycle can be attributed to the fields of publishing, i.e. robots and artificial intelligence. Bots help spread fake news and increase the apparent popularity of fake news on social media. Although bots still exist, more often than not, the spread of fake news is the result of real people, usually acting innocent. This leads us to the other main category, the human motivations of the user to tend and accept fake news. Social networks change other readers' perception of the quality of a message by highlighting the like index of a post, the usefulness of one's opinion. And changes his mind about the subject of the message itself. Research synthesis also shows that people share fake news more than real news for various reasons.

The present study aims to investigate and analyze the content of websites and virtual social media using a psychological operation technique in the field of public security.

The method of this research is qualitative research. Due to the nature of the research, a content analysis method was used, and the statistical population in this part of the research includes 539 items of news and articles related to the psychological operation and public security on the websites of “Hamshahrionline”, “JaameJam online”, and social media including the Young Researchers Club Telegram channel and the “KhabarFowri News” Telegram channel. The statistical sample of this part of the research was selected based on the content analysis of 265 items of content in various formats in social networks and 274 items of content in the above-mentioned websites using sampling. Also, to collect information; the content analysis tool, variable coding, and reverse questionnaire were used.

The findings of this research indicate that the studied media have used the psychological operation technique of "repetition" more than other techniques in the preparation, production, and dissemination of news and content in the field of psychological operation.

Aedes mosquitoes, especially Aedes aegypti and A. albopictus, due to their special biological and ecological characteristics, have high adaptability and establishment power in different weather conditions, including Iran, and for this reason, they are called invasive mosquitoes. These mosquitoes, which are known as a serious problem for human health, are very important in terms of transmission of very important arboviral diseases such as dengue fever, chikungunya, Zika virus, and yellow fever. Considering the importance of these diseases on the health system and human health, as well as numerous reports of the spread of arboviral diseases through Aedes mosquitoes in different countries, various programs have been proposed to control Aedes mosquitoes. As a result, introducing suitable methods to control Aedes mosquitoes can play a significant role in reducing the transmission of these diseases and maintaining human health. Therefore, in this review, we evaluate the use of each of the Aedes mosquito control methods.

This article is a narrative review of the introduction and effectiveness of different methods of controlling Aedes mosquitoes. Collecting information about control methods of A. aegypti and A. albopictus has been compiled without time and language restrictions from international scientific databases including Pub Med, Web of Science, Google Scholar, (ScienceDirect, Scopus, Elsevier, Lilacs) and Internal databases including, Scientific Information Database(SID), Iranian Medical Library(MedLib), Magiran, Civilica. The information collected based on the performance of each of the mentioned methods was extracted, categorized, analyzed, and used in compiling this article. Finally, out of a total of 10202 extracted articles, 123 articles were used in this research considering the inclusion and exclusion criteria.

In general, the goals related to the use of different methods of controlling Aedes mosquitoes are different depending on the country, epidemiological conditions, resources, and local priorities. But overall, disease prevention, reduction of mosquito population, stopping of disease transmission, prevention of mosquito establishment, disease spread, reduction of nuisances and finally identification of new invasive species are prioritized. The most appropriate methods of controlling Aedes are divided into five categories: 1. Environmental methods that include reducing the habitats and growth resources of mosquitoes 2. Chemical methods that are based on the use of various insecticides chemicals and insect growth regulators 3. Mechanical methods that include the use of various traps 4. Biological methods that include the use of natural enemies 5. Genetic methods include genetic engineering and mosquito sterilization techniques. It should be noted that each of these methods can play a significant role in the establishment of Aedes mosquitoes and the spread of arboviral diseases, and as a result, reducing the number of cases of infection and death in the health system.

Considering the introduction of different control methods for A. aegypti and A. albopictus and the priority of each of the control methods presented; it is important to mention that the method of controlling Aedes depends a lot on the environmental conditions of the region, the stage of mosquito establishment,  the population phase of mosquitoes and diseases caused by it. Therefore implementation of Aedes mosquito control programs through integrated vector management strategy is recommended, which requires the effective collaboration and coordination of national and local authorities and the general public for cost-effective control and lasting effects.

The Celiac National Institute has recently devised a diagnostic algorithm for celiac, which has been adopted from the most recent guidelines and articles worldwide. All Iranian provinces are requested to set all diagnoses based on the newest national protocol devised by the National Institute of Celiac Disease; however, some incompatibilities are observed. Therefore, this study was conducted to demonstrate these incompatibilities.

In this descriptive-analytical study, we enrolled 250 cases of celiac disease referred to the province registry system and revised the diagnosis based on the national protocol for celiac disease diagnosis. All data were analyzed using SPSS software version 26.

Among the 250 patients diagnosed with celiac disease, 88 (35.2%) had incompatibility. The mean age of the patients was 37.19 years. 28 people (31.8 %) were men. Results indicated that in 40.9% of incompatibility cases, only pathology tests were performed, and in 52.3% of incompatibility cases, only serological tests were performed. In 6.8% of cases, both tests were performed, but the diagnosis was indefinite. Pathological results indicated that 0.5% of patients were in Marsh 1, 19% in Marsh 2, 35.7% in 3a, 23.8% in 3b, and 19% in Marsh 3c phases.

There are cases of diagnostic incompatibilities between the most recent national protocol for celiac disease and physicians’ practice. Therefore, it is vital that practitioners are trained with the national protocol for celiac disease diagnosis..

Examining the challenges and opportunities of Iran's Law on Dissemination of and Free Access to Information is the subject of this research. Exploring in expert's opinions in the fields of communication and law the nature and form of the Law on Dissemination of and Free Access to Information was study. This research is grounded theory in essence and interviews were used to identify the opportunities and challenges facing the implementation of Law on Dissemination of and Free Access to Information in Iran. The statistical population of the research includes the experts and professors of the filed law. Analyzing interviews identified four axes: vagueness of the law exceptions, lack of law-enforcement guarantee, ambiguity in the concept of access to information, and the challenge of parallel laws. Therefore, the pathology of the behavior of government officials, citizens and the media professionals; changes in the performance of public officials; Cultivation and education on free access to information and achieving transparent documentation standards. Looking at these four challenges, it seems that the taking lessons from experiences of leading countries in this laws and a detailed review of the law in terms of challenges can provide appropriate solutions. It is possible that this law open windows toward the culture of transparency and supervision. Also reviewing this law should not turn into the formulation of principles for dismantling the law.

The present article tries to explain the relationship between concepts and social relations in Iranian society with Jung's psychological concepts and Jung archetypes by analyzing the novel "This Dog Wants to Eat Roxana" as a representation of social experience? Accordingly, using a conceptual model influenced by Jung's theories and using the method of psychoanalytic critique, archetypes; The self, the anima and the animus, the mask, the shadow, the numbers, the color, the wise old man and finally the individual unconscious are analyzed in the characters of the novel. Roxana falls with Kaveh arguing over her shirt. A shirt that represents the archetype of the mask and the mother. Kaveh is looking for her mother's arms, which she was deprived of when she was 3 years old, in this shirt. Kaveh who is looking for his anime not in Roxana (his wife) but in his mistress (Rahela). During the story, he removes the mask from his self-awareness, which begins with Roxana's fall, and faces his shadow (Mehran Bangi). The fall of Roxana leads to the revelation of Kaveh's shadow. In fact, Roxana's emotional relationship with Kaveh (Mehran Bangi) and Kaveh and Rahela (betrayal) lead to her downfall and death. A body left by Roxana who is attacked by a dog (Rahela's shadow). Raheleh's shadow is Kaye Kaveh's accomplice in Roxana's fall as a traitor. It is through the acceptance of these patterns that the individual subconscious and ultimately the pattern of social relations is manifested in Kaveh's social life.

One way to prevent financial distortion is to detect it early so that precautionary measures can be taken. The aim of this study was to investigate the ability of two models of forecasting distortions based on financial statements including M-SCORE Banish and F-SCORE Decho models and to measure their accuracy. The financial statements of 164 companies listed on the Tehran Stock Exchange between 2015 Will be studied until 2019. According to the results, the accuracy of Dechu F-SCORE criterion in identifying companies with the possibility of tampering and otherwise, is more than 70, which indicates the average ability of the model in detecting fraud. Also, the ability of the above-mentioned criterion with 73.17% in detecting fraud is higher than Banish model with 69.51%. In terms of diagnostic error, type I and II errors, which indicate the error of efficiency and effectiveness of the model, respectively, in the model of Decho et al. (2011) is much less than the model of Banish. Therefore, it can be concluded that Dechu F-SCORE criterion has performed better in cases of detecting the possibility of tampering with the financial statements of companies listed on the Tehran Stock Exchange between 2015 and 2019.

Housing sector and its price is influenced by many factors. These factors can be divided into supply and demand factors, and each of these factors includes many variables. Since the non-homogeneity of the housing market in all provinces, the evidence indicates that the housing market should be looked at regionally. This article aimed to analyze the factors affecting housing prices in Urmia. The research was applied with a descriptive-analytical approach, and various library methods, surveys, and interviews have been used to collect data. It was applied-developmental in terms of purpose and aimed to identify and build a conceptual model using structural equations (Smart PLS) for housing prices in Urmia and it was exploratory in nature. Also, it was a mixed methods research. The research population included 30 experts who were selected purposefully. The results showed that four social, physical, managerial, and economic components explain 70% of housing prices. In such a way that the combined coefficient of each component depends on other components as well. In other words, the composite coefficient showed to what extent the housing price growth in Urmia City has been affected by the shock on the economic component with other influential components. The analysis of the path coefficients related to the 4 investigated components showed that economic (E), managerial (M), physical (Ph), and social (S) components with values of 0.169, 0.014, 0.088, and 0.033 respectively have had the most impact on the housing prices in Urmia.

Decisions related to the payment of dividends are one of the basic components in the management policy of companies and are among the most important topics in financial literature, because dividends represent the major cash payments of companies and are one of the most important options. and decisions are considered before the managers. Therefore, the main goal of this research is to examine the relationship between the performance of the board of directors and the payment of dividends of companies that are members of the Tehran Stock Exchange. To achieve this goal, a sample consisting of 140 companies admitted to the Tehran Stock Exchange during the years 1395 to 1402 was considered. The data related to the research models were collected and sorted using Excel software, and preliminary calculations were performed on the raw data to reach the main variables of the research. The final data were transferred to the twelfth version of Evoz software for analysis based on the conceptual model of the research. Then the descriptive statistics of the research variables were analyzed. The results of the research showed that there is a significant and positive relationship between the performance of the board of directors and the payment of dividends.

The media plays an effective role in institutionalizing values and forming or changing national identity as the largest level of identity and acts as a variable lever of national identity. The aim of the current research was to analyze the role of mass and social media in the construction of national identity according to the students' lived experience, which was done with a phenomenological approach. The research method was applied in terms of purpose and qualitative in terms of the nature of the data. The statistical population of the research included all students of the first and second secondary courses in Ardabil city. The sample size was 17 students who were selected by purposeful sampling based on the principle of theoretical saturation and then the data were analyzed based on thematic analysis. The findings showed that based on the lived experience of the participants, the gap between knowledge, attitude and behavior towards national identity was evident in mass and social media; So that the national identity and its dimensions among teenagers whose dominant media is social media is less than among teenagers whose dominant media is mass media. Teenagers with the dominant use of mass media have tried to protect the traditional sources of national identity, on the other hand, the teenagers with the dominant use of social media represented themselves in favor of global or cosmopolitan identity.

In the present study, we seek to investigate the effect of sensory marketing components on brand equity by mediating audience satisfaction and brand credibility about the programs of the Islamic Republic of Iran TV.

The scope of the research includes all the audiences of radio and television programs, according to Morgan's table, The sample size was 384. to ensure the questionnaire, 449 questionnaires were randomly distributed among them. The questionnaire of this research, based on related research, has a five-choice question designed on a Likert scale. Also, for data analysis, linear regression relationships were used in spss software and path analysis in pls software.

The results showed that sensory marketing has a direct effect on brand credibility and also sensory marketing has a direct effect on audience satisfaction. In addition, the mediating variable of brand credibility has a direct relationship with brand equity, and also the mediating variable of customer satisfaction has a direct relationship with brand equity, and therefore, considering the establishment of four conditions between customer satisfaction and brand credibility in the relationship between sensory marketing and brand equity, It has a mediating effect.

Originality: 

This research, which was conducted for the first time on radio programs, seeks to investigate whether the components of the sensory marketing strategy have an effect on the special value of the brand through the mediation of customer satisfaction and brand credibility in the radio programs of the Islamic Republic of Iran. So that by creating special value of the brand, it can firstly maintain the maximum audience and secondly attract more audience for radio and television.

Through the convergence of satellite and internet networks, new communication technologies have opened the platform for the emergence of new actors, including governments, organizations, companies, groups, and new personalities to enter the field of foreign policy and openly compete with traditional powers in the field of international relations. Investigating the impact of new technologies on the emergence of new actors in the international field is the main goal of this research. In the theoretical framework of the research, the approach of liberalism and power and technology theorists (Nye and Toffler) have been used. The statistical population of the research includes all university professors and students of post-graduate courses in political science and communication sciences, experts and media experts across the country in 2019 and the sample size was estimated to be 384 according to Cochran's formula. This research was carried out in a descriptive-analytical way using the survey method and researcher-made questionnaire tools, and descriptive statistics and factor analysis statistics were used to analyze the research findings. The findings of the research showed that new communication technologies, including five factors of web and mobile social networks, cyber journalism, virtual space, satellite networks and the Internet (search engines), in the emergence of global actors (transnational and international organizations, multinational companies, new governments and terrorist groups) are influential. But these influences are not the same and the biggest impact is attributed to the two factors of the Internet and virtual space.

This research was conducted with the aim of investigating the effect of urban land use on the amount of biological pollution of urban runoff, the possibility of its reuse, and finding the amount of pollution in the quality of urban runoff in District 6 of Tehran. To carry out this study, first, urban sub-basins with different dominant land uses (residential, green space and office-commercial) in a geographical area with the same temperature change conditions in the 6th district of Tehran were determined and the land use distribution in each sub-basin was analyzed. Then, the sampling points at the exit positions of the runoff caused by the rainfall in the defined sub-basins were identified and the instantaneous sampling of the urban basin exit runoff after the rainfall in the spring season and field and laboratory measurements of the parameters and variables Qualitative (chemical and biological) and quantitative (flow rate and flow depth) were done. The quality relationship of urban runoff was measured based on biological variables in May.Pearson statistical methods and one-way analysis of variance were used to identify the relationship between land use and the results of laboratory measurements. In linear regression methods, total coliform was used as an independent variable to investigate the relationship and interaction with other parameters. The results showed the effect of green, residential, and office land use in increasing the amount of total coliform as an indicator of microbial pollution in urban runoff, respectively. The highest level of coliform in green space land use was 14 MPM, which is due to the use of chemical fertilizers. Also, EC with a value of 889 us, and TDS with a value of 640 mg/l, in green space usage was higher than other land uses, which could be attributed to soil washing by runoff. Based on the analytical results, the effective variables on the number of microbial pollutants were identified, and the relations of estimation and prediction of its amount based on the effective variables were introduced in the form of total coliform estimation equations.
