Today, one of the paradigms of the field of technology is quantum. A lot of research activities and international patents registration indicate that researchers are achieving quantum technologies at high speed. Expert surveys show that countries are trying to achieve quantum technologies with careful planning and focusing on creating scientific alliances. Certainly, the use of these technologies in the defense and non-defense sectors has opportunities and threats. Organizations are confused in the use of quantum technologies due to the complexity of knowledge and lack of knowledge of functional characteristics. In this paper, according to the functional characteristics and mission geography of the target organization, the quantum technologies that can be used in ICT and basic electronic missions were extracted with expert opinion. Then, a questionnaire of 76 questions (validity 0.638 and reliability 0.86) was prepared and sent to 27 people of the target community and questionnaire description sessions were held for the target community. At the end, completed questionnaires were collected and analyzed. From their analysis, “The mapping pattern of quantum technologies in ICT and basic- electronic missions of the target organization” was obtained. Results of questionnaire analysis and expert meetings with research and operational experts at the level of the target organization, the five priorities, (1. Quantum key generator, quantum key distribution and quantum DAS system, 2. Quantum communication based on sending and receiving a single photon on optical fiber and FSO, 3. Quantum gyroscope and accelerometer, quantum sensor and quantum clock, 4. Quantum processor, 5. Communications based on entangled pair properties by optical fiber and FSO, quantum radar) were determined for the target organization.

In different historical periods, one of the important geopolitical regions for Iran's security has been the South Caucasus region. China is trying to revive the historical Silk Road with a new one-belt-one-way plan, which used to start from China and lead to Europe through Iran and the Caucasus. Iran has a fundamental position in the plan of this corridor; the kind that reaches the Black Sea from Chabahar through the North-South corridor and passes through Armenia, Georgia, and Russia. After the ceasefire in the second Karabakh War, an agreement was reached between Azerbaijan and Armenia, one of the provisions of which is the plan to reopen the old roads. Still, Azerbaijan has an idea beyond the old one-way under the supervision of Armenia and wants to create a west-east corridor in the Zangezor region, directly under the supervision of Baku. This action violates the territorial integrity of Armenia, and also, causes the destruction of Iran's border with Armenia. On the way to creating the western-eastern corridor of Zangezzor, not only the Republic of  Azerbaijan but also many countries support the creation of this corridor. Now, the main question of this research is, what effect does Azerbaijan's plans to create a new corridor have on Iran's security? These countries are pursuing goals such as the creation of NATO's Turani Corridor, a permanent source of energy, and ultimately this extravagance will lead to the blockade of Iran in the northwest and the loss of one of the old crossings and highways.

The purpose of this study is to identify and evaluate the factors (internal and external) affecting the ecosystem of corruption in sports, so by identifying these factors, competitive corruption is analyzed. The research population is 23 university professors who have a history of research and study in the field of corruption. Based on the literature review and research background, 11 indicators were identified and extracted in 4 main dimensions: a) Contemporary Sports Characteristics. b) Governance. c) Extrapartial Levels. d) Consequence. To analyze the data, the combined method of fuzzy multi-criteria decision theory including ANP based on DEMATEL was used. The results showed that the “Consequence” index and “Extrapartial Levels” were the most effective factors, as well as the indicators of the “Contemporary Sports Characteristics” and “Governance”, were recognized as the most Impressive factors. The results of factor prioritization showed that the main indicators of Governance have the highest final weight. Although the Consequence in the corruption cycle is the last stage of this phenomenon, but in the effectiveness cycle, as the first and most effective indicator, it affects other criteria, because as the primary stimuli, the possibility of perceiving the risks associated with participation. It also explains the profit and loss conditions of corrupt activities. By adapting the system of crime and punishment, increasing financial crimes and severe disciplinary sanctions of corrupt people, severe restrictions on pardoning corrupt officials and preventing their re-entry, and establishment of monitoring systems can play an effective role in reducing sports corruption.

The purpose of this research is to identify and evaluate the factors (internal and external) affecting the normalization of corruption in sports, therefore, by identifying these indicators, sports corruption is analyzed. The research community consists of 23 international experts who have a history of research and study in the field of corruption. Based on literature review and research background, 15 indicators were identified and extracted. For data analysis, the combined method of fuzzy multi-criteria decision theory including: ANP based on DEMATEL was used. The results of the causal-disability relationships of this research showed that the indicators of the external world (8 indicators) were recognized as the influencing factors (cause). Among these, the lost paradise index, the frequency of corruption opportunities, and the low cost of participating in corruption were the most effective, respectively. Establishing a monitoring and investigation system to identify corrupt structures and limit the opportunities for corruption, adapting the crime and punishment system, trying to deal with indifference and social numbness, creating efficient educational systems to bring the society together. With the strategy of denouncing corruption, creating incentive mechanisms for whistle-blowing actions can greatly reduce the tolerance of corruption in the society and eliminate the ease of participation in corruption.

Considering the high prevalence and negative effects of borderline personality disorders, it is important to know as much as possible about this disorder and to identify the predictors and variables of this disorder.

The present study was Mediating role of experiential avoidance in predicting borderline personality disorder based on childhood trauma.

The present study was a correlational description. The statistical population included all male patients diagnosed with borderline personality disorder admitted to psychiatric hospitals in Shiraz in 2022, which were selected using targeted sampling of 60 people. Data collection was done using the childhood trauma questionnaire (2003), the experiential avoidance questionnaire (2011) and the short scale of borderline personality disorder symptoms (2009). To analyze the data, path analysis test, structural equations and Smart PLS software were used.  

The findings showed that there is a significant and positive relationship between childhood trauma and experiential avoidance (R2=0.711; p<0.05). Path analysis findings also showed that childhood trauma plays a significant role in predicting borderline personality disorder (path coefficient 0.546) and also the avoidance of experience plays a mediating role in the relationship between childhood trauma and borderline personality disorder, so that the path coefficient is 304. 0/ has shown a significant decrease (p<0.05).

The results showed that experiential avoidance has a mediating role in predicting borderline personality disorder based on childhood trauma, so it is necessary to pay attention to the component of childhood trauma along with attention to experiential avoidance as a model to reduce the severity of psychological complications.

This study is aimed to compare the characteristics of tenacity and its components among women with consanguineous and non-consanguineous marriages. This research is conducted in a descriptive-correlational manner. The statistical population of the study consists of married female students of Payame Noor University of Mashhad in 2019. Finally, by removing the insignificant data, 38 people completed the abridged tenacious scale questionnaire (AHS) in an accessible and voluntary manner online. According to the results of independent t-test, a significant level (0.038) is obtained for tenacity and its control component is obtained with a significant level (0.014). It indicates that there is a significant difference between the level of tenacity and its control component with consanguineous and non-consanguineous marriages. But no significant difference is found in the components of commitment (0.076) and struggle (0.136). Based in the findings of this study, tenacity, especially its control component, can play an effective role for women with consanguineous and non-consanguineous marriages.

The present study was a Prediction of corona anxiety based on attachment styles and mind reading through eye processing. The research method was a descriptive correlation. The statistical population included adults (age range 30 to 50 years) living in Tehran (districts 2-18-5-3-22) in the years 2021 and 2022. The sample size was 300 people who were selected by the available sampling method. The research tools included Corona Disease Anxiety Scale (CDAS) by Alipour, et al. (2019), Experiences in Close Relationships (ECR) by Brennan et al. (2000), and Reading Mind from Eyes Test (RMET) by Baron-Cohen et al. (2001). The results of the regression test showed that anxious attachment (P=0.001 and β=0.19) together with mind reading through eye processing (P=0.006 and β= -0.16) predicts Corona anxiety. but the avoidant attachment style (P=0.74 and β= -0.02) was not a significant predictor for Corona anxiety. Also, the results showed that the predictor variables were able to predict 0.05 of the variance of the Corona anxiety variable. The result of the present study shows that paying attention to anxious attachment style and mind reading through eye processing by psychologists can help to explain corona anxiety in adults.

The main objective of this study was to investigate the mediating role of emotion regulation strategies in the relationship between early maladaptive schemas with adolescent internalization and externalizing behavioral disorders. This study was applied and correlational study. The study population consisted of all secondary school students of Shiraz. Place sampling method used and total of 200 questionnaires were collected. To collect data three questionnaires included Cognitive Emotion Regulation Questionnaire-Kids, Young Early Maladaptive Schema Questionnaire (Short Form), and Achenbach child behavior checklist (CBCL) questionnaire used. In order to analyze the data Pearson correlation and path analysis were used. The results showed that emotion regulation strategies has a mediating role in the relationship between early maladaptive schemas and internalization and externalizing behavioral disorders (P<0.05). Early maladaptive schemas have a significant effect on internalization and externalizing behavioral disorders (P <0.05). Moreover, the results of the study revealed that emotion regulation strategies had a significant positive effect on internalization and externalizing behavioral disorders (p<0.05). In general, the results of the current study demonstrated that early maladaptive schemas by mediation of emotion regulation strategies can cause the occurrence of internalization and externalizing behavioral disorders; the fact to which parents and authorities in the country’s educational system should give special consideration.

The COVID-19 pandemic caused many businesses to face problems and created job insecurity, leaving many workers and employees stressed about losing their jobs. Therefore, the current research aimed to analyze the impact of workplace safety management measures on the behavior of organizational citizens concerning the role of job insecurity and the perceived risk of COVID-19 among the employees of Mashhad Social Security Organization.

The current applied research is a descriptive survey. The research population is all 560 employees of the social security organization of Mashhad city. The sample size was estimated based on Morgan’s table using a convenience sampling method, with a total number of 225. The data collection instrument was Wu et al.’s (2022) standard questionnaire, used to check construct validity and confirmatory factor analysis. Cronbach’s alpha coefficient and composite reliability were used to measure reliability, and the results showed that the questionnaire was adequately valid and reliable. The data analysis also involved structural equation modeling conducted in Smart PLS.

The results showed that workplace safety management measures have an impact on organizational citizenship behavior and the perceived risk of COVID-19. Also, the perceived risk of COVID-19 has a positive effect on perceived job insecurity. Yet, the perceived risk of COVID-19 does not influence organizational citizenship behavior and does not mediate the relationship between workplace safety management measures and organizational citizenship behavior. Workplace safety management measures have an impact on perceived job insecurity, and job insecurity has an impact on organizational citizenship behavior.

In light of the present findings, it can be concluded that workplace safety management measures are among the most important programs and strategies of organizations to increase citizenship behaviors, support employees, and provide safe conditions in an organization.

Today, despite the nationwide vaccination of the society to prevent the epidemic of the Covid-19 virus, some people refuse to inject the Covid-19 vaccine as the main self-care behavior, which can have specific reasons.

The present study was conducted with the aim of investigating the role of personality and demographic characteristics in the injection of the covid-19 vaccine as a measure to prevent the spread of the corona virus in Mashhad.

The method of this research was descriptive-correlation. The statistical population consisted of the people of Mashhad in the year 2022, of which 517 people (62.1% vaccinated and 37.9% unvaccinated) were selected in an accessible and voluntary manner and completed the Brief HEXACO Personality Questionnaire (2013) and Demographic Characteristics Questionnaire in Person. The collected data were analyzed by Yeoman-Whitney test in SPSS software version 26.

The results showed that there is no significant difference between vaccination and non-vaccination in the five personality components of Emotionality (P=0.19), Extroversion (P=0.44), Agreeableness (P=0.88), Conscientiousness (P=0.86) and Openness to Experience (P=0.20). However, there was a significant difference between the vaccinated and non-vaccinated groups in terms of the personality component of Honesty-humility (P=0.03) and the demographic characteristics of gender (P=0.002), age (P=0.001), level of education (P=0.001), and employment status (P=0.001).

The personality trait of honesty-humility and the demographic characteristics of gender, age, level of education and employment status play a role in the matter of injecting the Covid-19 vaccine as the main self-care behavior. These results can be used to promote and encourage vaccination in future crises.

The goal of this study is to analyze the introduction and expansion of factors of political modernity in the Qajari government era. Cultural exchange with the west led to a flourishing in the field of political modernity. Intellectuals knowing about such concepts were the first to indirectly mention these concepts. Intellectuals played the greatest role in this transition and in spreading political modernity factors in Iran. These included the necessity of having a parliament and bureaucracy, constitution, centralized government, civil society, legitimacy and Separation of religion from government. In the time of constitutional era, much effort was made to meet these demands and for the very first time such demands were asked for in the traditional system of tyranny in Iran. Due to political modernity, he design of these discussions and the development of these developments began during the Qajar government, especially Nasser al-Din Shah, but to put these demands into practice was time consuming and needed time to pass.

The occurrence of corruption in sports is not a new phenomenon. However, in recent years, corruption in sports has taken on a complex and multifaceted form. It is no longer acceptable to consider isolated individuals or limited organizations as the main perpetrators of corrupt activities, because corruption has found a systemic character. And corrupt behaviors are usually carried out through a network that helps to hide the path of corruption. The purpose of this study is to analyze network corruption in sports. The research population is 18 university professors who have a history of research and study in the field of corruption. The factors of this research have been identified by reviewing the theoretical literature and research background (12 indicators). Multi-criteria decision making method including Fuzzy Delphi was used to analyze the data. Based on the findings of the present study, The highest consensus of experts on network corruption was assigned to the index of "diversity of skills and expertise of members" and the lowest was assigned to the criterion of "monopoly".

Bridges are counted as one of the most important and vulnerable structures in the vital veins of every country. The abundance of the concrete box deck bridges with concrete arches on the one hand, and the complex dynamic behavior resulted from special geometric conditions of this class of bridges which have made them more vulnerable on the other hand, were aimed to be studied in this research. In this study, a model of a concrete box deck bridge with concrete arches and the appropriateness of using lead-rubber bearing system were examined, and ultimately, two states of the bridge with and without seismic isolation were assessed by fragility curves, and the amount of possible seismic damage have been obtained. The study results were analyzed by modeling the bridge in the CSi Bridge finite-element software in three dimensions and under the excitation of 100 pairs of real accelerogram and under nonlinear time-history analysis, and the responses of the elements were extracted. So that, compared to the state without seismic isolator, the maximum relative displacement in the model with seismic isolator has decreased by 55 and 28 percent in the longitudinal and transverse directions; respectively. Also , based on the result of modal analysis and comparison of t the vibration period, the results show a significant increase in the first to third period of vibration of bridges in the state with seismic isolation compared to the without seismic isolation. The results of studies indicate that In this bridges with seismic isolation have reduced the drift of columns significantly so that the seismic fragility of the bridge system has been reduced at different levels of damage.

Yeasts have been used as food additive containing protein and vitamins group B for fish nutrition. The present study was aimed to investigate the effects of probiotic, AQUALASE on growth, immunity and hematological parameters of Benii, Mesopotamichthys sharpeyi. Fish were assigned to 12 experimental tanks (with stocking rate of 30 fish per tank) as 3 experimental treatments with three replicates. The treatments were: T1: 0.05% probiotic, T2: 0.1 % probiotic, T3: 0.15% probiotic. Also, one group fed with probiotic -free diet was considered as control. After 60 feeding with experimental diets, it was recognized that probiotic improves the growth indices including: weight, specific growth rate, daily growth rate, feed and protein efficiency and also decreases feed conversion ratio. In this regard, the best results obtained in fish fed with 0.15 probiotic (T3). Survival rate values showed no significant differences between experimental groups. The values of hemeoglubin, MCH and MCHC increased only in T3. In conclusion, with regard to positive effects of AQUALASE on growth and hematology of Benii, this probiotic can be as a growth enhancer for this species.

Curved bridges exhibit complicated responses in the course of an earthquake, due to their distinctive geometric status. Thereby in this study, the effect of different curvature radii on the seismic damage probability of curved multi-frame concrete box-girder bridges was investigated and compared to straight bridge. Three-dimensional probabilistic seismic vulnerability of the curved multi-frame concrete box-girder bridges was delved in the near-fault events subjected to three-directional ground motion excitations (considering vertical component of earthquake). Bridge models were analyzed in 5 different radii subjected to 80 near-fault earthquake records and taking into account all demand uncertainties (14 uncertainties inherent of bridge, along with the earthquake uncertainty) as well as capacity uncertainties. Of all the bridges of this class, a total of 10 completely random geometries, representing geometric status of entire statistical population of curved box-girder bridges in California, were selected for each of the six bridge radii using the Latin-Hypercube Sampling technique. Having performed nonlinear dynamic analyses, the fragility curve of each bridge component was plotted, and the curvature effect on the vulnerability of various bridge components was investigated . Thereby, comparing seismic demand with the capacity of components through Monte Carlo simulation strategy, damage probability of the bridge system was estimated.

Bridges are one of the major infrastructures of a country, which, in the event of severe seismic activity and the occurrence of collapse, can cause severe damage in different regions and create a severe crisis. Bridges with very long spans have always been a great challenge for engineers throughout history. Cable-stayed types of bridges are becoming more and more popular in the construction of long span bridges due to their advantages. A great number of cable stayed bridges in the world are located in the seismic zone and also near active faults so the effect of near field excitations on the seismic vulnerability of cable stayed bridges should be investigated probabilistically in accordance with far field excitations. Generation of vulnerability functions in the form of fragility curves is a common approach for assessing bridges seismic vulnerability. In this article, a set of analytical fragility curves for a case study cable stayed bridge (the Bill Emerson Bridge) are developed based on Incremental nonlinear dynamic analysis (IDA). The findings represent the effect of near fault excitations on the vulnerability of this long span bridge model. For example, the probability of a complete and extensive damage state for the considered cable stayed bridge in 1.5g for far field is 10 and 32 percent respectively, while in the near field, this value increases to about 19 and 44 percent, that indicates increase vulnerability of bridge in near field. The median values of seismic fragility for the considered bridge model decreased significantly in near field excitation in the Extensive and Complete damage states. The results can guide future regional risk assessments regarding the importance of including or neglecting near field excitations impacts on cable stayed bridge’s vulnerability.

In a process of producing electronic components, the components are never exactly the same. This causes the output signal from radio transmitters (even similar ones) to be different. The differences are negligible, so it does not violate telecommunications standards.  But these inherent and unique differences can be considered as physical layer features and used to authenticate radio transmitters. Normally, authentications based on software can be forged. Forgery based on the inherent characteristics of radios is very difficult or impossible. Because it requires a lot of knowledge, money, and time. The power amplifier is the last part of the transmitter. So it has the most effect on the transmitter output signal. In previous researches, the receiver assuming to have the SNR value of the received signal, used the coefficients of the power amplifier nonlinear model to classify the transmitters. In this paper, a new feature is provided to perform authentication operations independently of the SNR value of the received signal. The simulation results show that using the proposed new feature, the radio transmitter authentication process from low SNR values (at least 15dB) to high ones, without the need for SNR measurement, is performed well with a likelihood of more than 80% success.

The emergence of resistant fungal species, as well as relatively high side effects of antifungal drugs, have prompted researchers to develop new methods forcing action against fungi. The aim of present study was to evaluate the antifungal effects of hydroalcoholic extracts of Nigella sativa and Urtica dioica on Candida species isolated from clinical specimens in comparison with amphotericin B.

In the current study, antifungal effect of hydroalcoholic extracts of Nigella sativa and Urtica dioica, which were prepared by soaking and soxhlet methods, against 11 Candida isolates (Candida albicans and Candida parapsilosis), were measured using broth microdilution method. Candida isolates were exposed to different concentrations of the extracts, and the minimum inhibitory concentration (MIC) of each extract was determined.

Both hydroalcoholic extracts of Nigella sativa and Urtica dioica showed antifungal effects against candida isolates. The MIC90 values of soaked and sox let hydroalcoholic extracts of Nigella sativa for Candida albicans and Candida parapsilosis were 25 and 12.5 mg/ml, respectively. Moreover, MIC90 values of soaked and sox let hydroalcoholic extracts of Urtica dioica for the candida species in both methods were 12.5 mg/ml. In addition, MIC90 values of amphotericin B against Candida albicans and Candida parapsilosis were obtained 1.0 and 0.5 μg/ml, respectively.

Although amphotericin B as an effective drug has a better antifungal effect against candida species, hydroalcoholic extracts of Nigella sativa and Urtica dioica also have acceptable antifungal effects on Candida albicans and Candida parapsilosis. Among them, Urtica dioica extract has a better effect than Nigella sativa extract.

In recent years, a new generation of networks called software defined networks (SDN) has been  introduced whose main focus is on separating control logic from hardware and concentrating it on acentral software called the "controller". SDN improves the network efficiency and reduces the expenses. Despite numerous advantages, SDN faces a lot of challenges such as scalability and reliability that can be fixed through physical decentralization of the control level and introduction of distributed controllers. However, the distributed controllers also face challenges including scalability, stability, and coordination strategy. This research deals with the improvement of distributed controllers’ scalability using the concept of load balancing. For this purpose, we have suggested that a controller load detection function (CLDF) be placed on each of the related controllers, and if the load exceeds the threshold level, the new load be transferred to a controller with the least load. The suggested method is implemented on the Floodlight  controller in a distributed manner, and implemented on Ubuntu 14.04 operating system using the mininet simulation platform. The simulation results show that suggested method causes an average growth of 31.6 percent on the transition rate.
