Taleghani Street in Tehran, as one of the city's major urban axes, has witnessed numerous architectural and social transformations due to its geographical location and historical significance. Serving as an administrative and governmental hub, the street has been influenced by prevalent architectural styles and overarching governmental policies during its formation. Examining the facade transformations of the buildings along this street offers an opportunity to analyze how political, economic, and social factors have shaped the architectural identity of the urban landscape over the past century.This study aims to reassess the historical evolution of the northern facade of Taleghani Street, focusing on administrative and governmental buildings from Palestine Square to the Sepahbod Qarani intersection. It analyzes the impact of political, economic, and social factors on the facades of these buildings across three historical periods. Beyond identifying the dominant architectural styles of each period, the research also investigates the interplay between architecture and governmental policymaking.The study employs a descriptive-analytical research method, integrating historical studies with field observations. Eight prominent buildings along the northern facade of Taleghani Street were selected as case studies, and their architectural features were analyzed with an emphasis on political, economic, and social influences. Data obtained from library resources and historical documents were combined with field observations.Findings indicate that during the first Pahlavi era, nationalist policies led to the development of facades characterized by horizontal lines and the use of indigenous materials. In the second Pahlavi period, Western influences and favorable economic conditions resulted in the adoption of international architectural styles and modern construction technologies. After the Islamic Revolution, ideological policies and economic constraints led to simpler facades emphasizing local materials and functionalist design. The study highlights that building facades on Taleghani Street not only reflect architectural transformations but also serve as a medium for expressing governmental policies and socio-economic changes throughout different periods.

The alignment of the physical and psychological characteristics of conservatories with the self-actualization mechanisms is one of the most influential implicit factors in the learning and talent development processes of learners. While being in the space, the students are unconsciously affected by its constructive features, and this can be an advance or a hindrance in the way of learning. One of the most reliable data in the analysis of this effect is the students' mental perception of characteristics of the space. By understanding the space, they can provide valuable opinions on the design of the educational environments. In this study, with the Q method and a quantitative approach in statistical analysis, with the participation of 30 students of two conservatories in Bam city, their understanding of the physical characteristics of space has been analyzed with the aim of promoting and facilitating self-actualization during education. In this study, two contemporary art schools in Bam city were investigated in the field. The Hakim Farabi and Fadak art schools, which were built after 1990 and have some special architectural features, were selected. The steps of implementing this method include selecting the subject group (P), collecting factors (Q), sorting, interviewing, analyzing data, and finally factor analysis. First, 30 students were selected to conduct the research. In the first step, each student was asked to list 8 to 10 physical factors that, in his opinion, could affect him in the process of learning the lessons. By examining the factors mentioned, which were 278, it became clear that the students had mentioned 87 unique and non-repeating factors. At this stage, it was necessary to list the factors based on the frequency and importance of the item. The screening of the factors was carried out by a panel consisting of two university faculty members, one doctoral student, and one student as a representative of the statistical population. Three rounds of factor screening were conducted and finally 48 factors were identified. The extracted components were organized on a Likert scale and 10 students were asked to rate the components based on their importance from 1 to 5. Finally, based on the score obtained for each factor, 24 items were finalized as the Q set in this study. The results of the exploratory factor analysis of the data show that factors including "mental and physical comfort", "facilities and equipment" and "quality of educational space" can be identified. Among the 24 specified variables, most of the roles are the amount of receiving natural light and daylight, reducing and controlling annoying noise from inside and outside the classroom, and the arrangement of chairs and tables suitable for each course and the flexibility of the space in changing the position of the furniture according to the needs of each lesson. In addition, it was shown that characteristics such as number of students in the class, the presence of additional equipment such as a clock in the class and the smell of the air, have the least effect on the students' learning process.

The measurement of public library services in the area of social entrepreneurship can be significantly impacted by the use of the standard tool for measuring social entrepreneurship. This study aimed to develop and validate a social entrepreneurship scale for its use in Iranian public libraries.

In terms of purpose, the present research is applied, and in terms of data collection it is a descriptive correlation. The statistical population of this research includes all the librarians of Iran's public libraries, amounting to 7000 and of them, 300 librarians were selected by multi-stage cluster sampling method. A researcher-made questionnaire was used to collect data and the instrument's validity was calculated using content validity and exploratory and confirmatory factor analysis. The reliability of the tool was also higher than .60 using Cronbach's alpha for each index and was obtained by the binomial method. In this method, a value of .82 was obtained for odd items and.78 for even items, which showed that the questionnaire has the necessary reliability. The online questionnaire was provided to the librarians of public libraries in the country through the internal network of public libraries. The total number of collected questionnaires was 289.

Based on the findings of this research, all factor loadings of social entrepreneurship indicators in public libraries (lifelong learning, emergency response, civic engagement, economic development, health, and diversity and inclusion) were obtained above .5, and the results of factor analysis, exploratory and confirmatory validity and appropriate reliability of the tool confirmed this. Considering the appropriateness of the social entrepreneurship measuring tool in Iran's public libraries, it can be identified as a valid tool in related research. The results of this research are useful for target groups such as library and information science students to evaluate social entrepreneurship services. It also could be useful for public library librarians and managers to provide social entrepreneurship services and policy-making in this direction. Finally, it can be said that the construction of this tool leads to a better understanding of the needs of society, better use of financial resources, improved coordination between public library managers and human forces, more freedom in choosing resources to satisfy the needs of society, and making more effective and efficient activities in public libraries.

Originality/Value: 

Public libraries, using social entrepreneurship, deal with challenges such as unequal economic access and unequal capacities of society in benefiting from public services. According to the review of the research background, the lack of research in the field of social entrepreneurship in public libraries was evident and most of the research in the field of entrepreneurship was done in general. On the other hand, a standard tool that can evaluate the state of social entrepreneurship in public libraries was not found in previous research. Therefore, the current research is innovative from the thematic and methodological aspects. The present study is helpful because it designed and validated the social entrepreneurship measurement tool in the context of public libraries in Iran.

Considering the location, the frequency of faults and the probability of earthquake, district 20 is distinguished from other areas as the most dangerous region of Tehran. Due to the uncertainty of the time of the previous destructive earthquake, the probability of activation of these faults is very high.

Regarding the exploratory nature of this research, the environmental scanning technique was used, and due to the dominant approach of this research, which is future research, the Delphi technique was used. Structural analysis has been used in MicMac software to analyze data.

The results of the dispersion of the variables indicate the instability of the system in the studied area, and accordingly, five categories of variables were identified.

The results showed that based on the quantitative analysis of the Scenario Wizard software, three golden, static and crisis scenarios were obtained for the 2051 horizon of district 20, which is the most valid scenario related to the static scenario.

The outbreak of COVID-19 caused many changes in people's lives, and most of the people's needs were met in non-personal and virtual ways. COVID-19 patients often need rehabilitation after the end of the infection period. This study aims to investigate comparison of the effects of center-based pulmonary rehabilitation versus remote pulmonary rehabilitation on the prognosis of patients with COVID19.

52 patients were divided into two groups. In-person and remote pulmonary rehabilitation was examined in this study. Both groups received respiratory physiotherapy. One group referred to a rehabilitation center and the other received instructions remotely. Both groups were followed up over three months using the 6-minute walking test.

The mean age of the patients was 43.40 ± 7.74 years, and 53.8% of them were men. There was not any significant difference in terms of age (p=0.406), gender (p=0.404), and occupation (p=0.878) between the two study groups. There was not any significant difference in quality of life (p=0.451), anxiety level (p=0.310), and depression score (p=0.554) between the two study groups. In addition, Barthel index studies showed that there was not any significant difference between the two groups from this point of view. There was not any significant change in the values of 6-minute walk in any of the attendance (p=0.273) and non-attendance (p=0.185) groups during the three-month follow-up. Furthermore, the changes in the 6-minute walk did not show any significant difference between the two groups (p=0.212).

The results of our study showed that none of these two methods are superior to each other in improving the condition of patients. However, it should be kept in mind that the non-attendance method is preferable to the in-person process because it does not require the patient's presence, spending a lot of time and wasting time. More studies are needed to complete these results; moreover, discussing about Internet access restrictions and related problems should also be considered.

Muslim thinkers have proposed various criteria for Abode of Islam (Dār al-Islām). Given the importance of convergence in the Islamic world and the orientation of existing political systems towards union-based approaches, a comparative examination of this concept has gained new significance in order to achieve a shared discoursive reading. The main question of the research is: What is the concept of Dār al-Islām from the perspective of Shiʿa and Sunni thinkers, and how is it possible to reconcile the various and differing criteria they have offered in this regard? 
Drawing upon a descriptive-analytical method, along with a comparative approach and the use of library tools for data collection, this research first presents the views of prominent Shiʿa and Sunni thinkers who have discussed Dār al-Islām and goes on to offer a new interpretation of the concept of Dār al-Islām and considers the possibility of reconciling various criteria around a common axis.

The cultural complexes, particularly cultural centers, play a crucial role in enriching the leisure time of teenagers and young people, fostering their awareness, and creating a platform for desirable social behaviors. In addition, these centers play a key role in shaping the cultural identity of young people and fostering a sense of community. They also offer a platform for creative expression, artistic growth, and social engagement, which are all crucial for individual well-being. The effectiveness of architectural design on the configuration and spatial relations of these types of spaces is crucial in optimizing the functional efficiency of these centers. For instance, the space design can significantly influence the way people interact with each other, the physical environment, and the activities and programs offered by the center. Moreover, integrating sustainable materials and energy-efficient systems can lessen the building's environmental impact while enhancing indoor comfort and health. Effective design strategies can include using natural light, ventilation, and insulation to reduce energy consumption and create a sense of connection to the outdoors. This approach can also enhance the space's aesthetic appeal, making it more inviting and enjoyable for visitors. By incorporating these strategies into design decisions, architects can create spaces that are not only functional but also sustainable and environmentally friendly. This research aims to investigate the identification of effective components in the spatial dialectic relationship of Tehran's leading culture centers from the second Pahlavi period to the contemporary period. This research aims to provide valuable insights into the evolution of cultural centers in Tehran and identify the key factors that contribute to their success. By analyzing the spatial dialectics of these centers, we can gain a deeper understanding of how architecture can influence the social and cultural dynamics of these spaces. The research method employed in this study is quantitative in terms of the applied developmental goal and relies on a mathematical simulation approach to analyze the physical geometry of the researched buildings. This approach enables a detailed analysis of the spatial relationships between different building components, such as rooms, corridors, and outdoor spaces. Also, it facilitates the identification of patterns and trends in the data that can inform our understanding of how architecture influences human behavior. This comparison is conducted through field observations and space analysis using computer modeling in DephtMapX software. By analyzing real-world data and using computer simulations, we can test different design scenarios and evaluate their effectiveness in achieving specific goals. Besides, this approach allows us to account for factors that may affect human behavior, such as lighting, acoustics, and temperature. During the research, an analysis of three indicators of spatial dialectics–namely, "integration," "connection," and "access"–was conducted on case samples of the research. The results revealed that the element "interconnection" has a homogeneous value and an average of 4.75. This value represents the visibility and openness of the spaces where there is a cultural center in the vicinity. Furthermore, this analysis highlights the importance of creating connections between different spaces within a cultural center, as well as between different centers themselves. Simultaneously, the amount of "connection" and "access" exhibits significant variety, indicating the number of entrances and diverse paths within the structure of the studied architectural space. This variability reflects the need for flexibility and adaptability in architectural design and a willingness to experiment with different layouts and configurations. Analyzing the spatial dialectic relationship and the success in the function of Tehran's well-known cultural centers underscores the necessity of "physical and spatial integration" and diversity of "routes and accesses" as two effective strategies in architecture.By incorporating these strategies into design decisions, architects can create spaces that are both functional and aesthetically pleasing. Architectural design can be further enhanced by incorporating natural elements such as light, water, or plants into the design to create a sense of connection between humans and nature. Additionally, incorporating interactive elements such as art installations or performance spaces can encourage social interaction and community engagement. Paying attention to spatial organization, functional arenas, aesthetic appeal, and strategically placing space-dividing components using transparent materials contributes to overall use, efficiency, and emotional response within architectural spaces. By prioritizing these factors in design decisions, architects can create spaces that are not only functional but also beautiful and engaging. Comprising technology such as digital displays or interactive exhibits can enhance visitor engagement and provide new opportunities for interactive learning experiences. Incorporating flexible seating arrangements or movable furniture can facilitate different types of activities and events within a cultural center. In conclusion, this research aims to provide valuable insights into the evolution of cultural centers in Tehran by analyzing their spatial dialectics relationship over time. The findings highlight the importance of creating connections between different spaces within a cultural center and between different centers themselves. By integrating these strategies into design choices, architects can develop spaces that are both practical and visually appealing.

Throughout history, people have sought ways to enhance their lives and find joy through various mechanisms. This pursuit has increasingly highlighted the importance of work participation, drawing the attention of numerous scientists. Consequently, the concept of work engagement has gained prominence in organizational behavior research (Shoul & Sedaghat, 2016). Work engagement is defined as the extent to which individuals are psychologically connected to their current job (Mudrack, 2004). Those who are highly involved in their jobs seldom contemplate leaving and are likely to remain with their organization for the long term (Brown, 1996). Studies indicate a global decline in employee engagement, with less than 30% of employees being actively engaged, which is considered low. This disengagement results in substantial financial losses for countries’ economies each year. Therefore, it is crucial to focus on comprehensive and diverse developments and their impact on organizational competitiveness, as well as the role of employees in job involvement and the promotion of organizational virtues to achieve objectives. This is particularly significant given the emergence of new management styles, such as quantum management. In today’s world, the need for employee occupational involvement in organizations has never been greater, and management practices within organizations have garnered increased attention from management scholars and practitioners (Hashmi & Pouraminzad, 2019).Management scholars assert that 21st-century managers must adopt innovative management strategies to foster employee engagement, thereby reducing thoughts of resignation and potentially boosting productivity and efficiency (Mezginezhad, Ayati & Pourshafei, 2017). Quantum management is one such strategy (Mirsafian, 2015). In modern organizations, ethical considerations, particularly organizational virtue, have gained prominence due to various advancements. While organizations rapidly evolve in competitive terms, virtues and virtue-centric topics have received scant attention. Bird and Water (1989) observed that organizational discourse often lacks a moral dimension (Moshabakiesfahani & Rezaie, 2013). Hence, employing organizational virtue can elucidate ethics within organizations. Virtues-encompassing habits, desires, and actions—are conducive to individual and societal well-being. They are endorsed and cultivated at both personal and communal levels, ensuring their propagation and sustainability (Zemaheni et al., 2013). The findings of this research could serve as a roadmap for educational organization managers to enhance employee job involvement through contemporary management practices. This paper answers this question:What impact does organizational virtue have on quantum management and occupational conflict in South Khorasan province?

This study employs a descriptive, correlational design and is both applied and quantitative in nature. The research population comprises all education and training employees in South Khorasan province, totaling 750 individuals in 2019, as per the official education report. Stratified random sampling was utilized for data collection. South Khorasan Province was segmented into several strata, including the General Administration of South Khorasan Province, Birjand, Boshruyeh, Zirkouh, Darmian, Khoosf, Mehdim, Sarayan, Sarbisheh, Tabas, Ferdows, Qaen and Nehbandan. From each department, a proportional number of employees were selected: 50, 33, 33, 11, 14, 12, 13, 12, 15, 15, 24, and 18, totaling 250 participants. This sample size was determined based on Krejcie and Morgan’s sample size, given the target population of 750. The distribution of administrative employees across the departments in South Khorasan province is detailed in Table 1.The instruments used for data collection were standardized questionnaires on quantum management, job involvement, and organizational virtue. The validity and reliability of these questionnaires were confirmed through the Cronbach’s alpha coefficient. Data analysis was conducted using SPSS and AMOS statistical software. The analytical methods employed included single-sample t-tests, Pearson correlation, simultaneous multiple regression, and structural equation modeling.

The study’s findings reveal that the overall average scores for quantum management and organizational virtue, along with their respective components among educational staff, are significantly above the theoretical mean score of 3. However, the average score for job involvement among educational workers is notably below the theoretical mean (p < 0.001). Additionally, the elements of quantum thinking and trust negatively impact job involvement, whereas quantum feeling positively influences it. While quantum management does not exert a direct significant effect on job involvement, it does have a substantial indirect impact through the intermediary of organizational virtue, contributing to job involvement. Furthermore, the model demonstrated adequate fit.

To investigate the effect of topical Polyvinylpyrrolidone‑iodine (PVP‑I) 0.6% on the clinical course of adenoviral keratoconjunctivitis compared with PVP‑I 1% and artificial tears.

We prospectively enrolled all patients over 18 years of age with a polymerase chain reaction (PCR)‑confirmed diagnosis of adenoviral keratoconjunctivitis who presented to the hospital between November 2022 and June 2023. Patients were randomized into 3 groups: artificial tears (control), PVP‑I 1%, and PVP‑I 0.6% eye drops, 4 times daily for 5 days. Clinical signs at presentation and at 6 follow‑up visits during the 1st 3 weeks of the acute phase were recorded. Patients were also followed up at 1 and 3 months.

Ninety‑four patients completed the study, of which 30, 31, and 33 were in the control, PVP‑I 1%, and PVP‑I 0.6% groups, respectively. The mean age of the patients was 37.2 years (interquartile range: 25-46). The PCR result was positive in 75.6% of patients with the clinical suspicion. PVP‑I, regardless of the concentration, was superior to the artificial tears in terms of time to resolution of lid swelling, discharge, and incidence of subsequent subepithelial infiltrates (P < 0.05). However, a concentration of 0.6% was equivalent to 1%. No significant adverse events were reported in any group.

The PVP‑I 0.6% topical drops are safe and well tolerated in patients with acute adenoviral keratoconjunctivitis. It can be substituted for the 1% solution as it has comparable effects in improving the clinical course and reducing subsequent complications.

 Invasive fungal infection (IFI) is a life-threatening condition, particularly in individuals with compromised immune systems.

 Our study aims to evaluate IFI in hospitalized patients with hematological malignancies.

 In this retrospective cross-sectional study, we evaluated patients with hematological malignancies admitted to two university hospitals in Tehran, Iran, from 2020 to 2021 for IFI. We selected only those patients who had been hospitalized for at least four days for antimicrobial treatment. Data analysis was conducted using SPSS-26 software, employing Mann-Whitney U, chi-square, and Fisher exact tests.

 During the study period, 60 out of 213 patients with hematological malignancies were admitted for antimicrobial treatment. The average age of the patients was 57.1 years, with fever being the most common symptom, reported in 63.3% of cases. We identified 24 cases of
IFI, including three proven cases (Candida spp.) and 21 probable cases. Statistical analysis showed a lower mean neutrophil count in the IFI group compared to the non-IFI group (3862 versus 12881, P = 0.001) and a higher mortality rate (58.3% versus 27.8%, P = 0.031).

 Our study revealed that severe neutropenia is a significant risk factor for IFI, and the mortality rate associated with IFI remains high despite advances in the treatment of hematological malignancies.

Several factors, such as fluid viscosity, density, and medium toughness, can influence the hydraulic fracture growth process. It is important to note that these parameters do not affect the growth process equally, and one or more of the parameters may have a more significant impact than the others. As a result, it can lead to one or more regimes. The regimes are named based on the process of energy dissipation, the most important of which are: first: toughness regime, where the most energy of fluid injection is dissipated due to rock failure, second: viscous regime, where the greatest input power loss is caused by the movement of viscous fluid in the crack. The research investigates crack growth in a brittle (elastic) rock medium employing linear elastic fracture mechanics (LEFM). The fluid is assumed to be incompressible and Newtonian. The study examines the growth of hydraulic cracks with various geometric shapes such as KGD and radial cracks. The results show that the semi-analytical method for solving the coupled governing equations of hydraulic fracturing has sufficient accuracy and high convergence speed. During the early stages of the hydraulic fracturing process, the KGD crack grows at a faster rate than the penny-shaped crack. However, at later stages, the growth of the penny-shaped crack greatly exceeds that of the KGD crack. Furthermore, the rate of KGD crack opening is higher than that of the penny-shaped crack. As a result, there is a significant decrease in the growth rate of the penny-shaped crack in the viscosity regime relative to KGD.

In order to increase the capacity to deal with earthquake hazards, increasing urban resilience has become a basic priority for most governments. Based on this, the current research was written with the aim of measuring the physical resilience of the peripheral part of the 20th district of Tehran against earthquakes.

The research method is applied in terms of purpose and analytical-exploratory in nature, which was used to analyze information using the AHP technique in Expert Choice software and the opinion of 25 experts.

 The findings showed that district 20 of Tehran city will face a serious crisis due to having many worn-out and marginalized structures, short-term residential units, old buildings, high population density, small area of residential land and narrow roads.

According to the obtained results, about 47% of the fabric of district 20 is highly vulnerable to the earthquake crisis. Therefore, appropriate policymaking to manage earthquake crisis, especially in strengthening buildings and land use planning in this area, is an inevitable necessity.

Bathhouse (public Bath)  as one of the well-known models of traditional Iranian buildings is important in the architectural literature, which is due to the heat exchange feature and energy storage in the body of this type of building. From this point of view, the fact that the whole design and pattern of these public baths are similar to each other needs to be investigated. In fact, traditional baths are not only an example of historical value but also this building has a special and valuable function in terms of energy storage and prevention of heat exchange. This study focuses on their thermal behavior because the main parts of the traditional baths are two dry and wet spaces in the spatial-functional hierarchy of this building, namely the tepidarium (garmkhaneh) and the apodyterium (sarbineh). In this study, the thermal crust of hot and dry climates in Iran will be investigated due to the limitations of the research only in terms of surfaces and geometric area, which is one of the three main components in heat exchange through the crust. This study tries to identify the body of these spaces in terms of measures to reduce the area to volume ratio by examining the walling of the tepidarium (garmkhaneh) and the apodyterium (sarbineh) as spaces sensitive to heat exchange through the envelope in traditional baths. This research has a quantitative post-positivist paradigm and a combined strategy of modeling and mathematical reasoning that for the meaningfulness of the responses, the relationship between heat loss through the envelope, and the effectiveness of reducing the power of the heating system based on the quantity of the area is understood by simulating traditional bathroom spaces and adapting design solutions. What is induced based on the study of proportions and comparison of surfaces and volumes of selected samples, is that the general design of apodyterium and tepidarium spaces, by increasing the floor area of walls and walls connected to spaces with lower temperature difference and also reducing the area to volume ratio in Outdoor-related building-envelopes has led to a reduction in temperature losses through the envelope.

Two of the important issues in the construction of structures located in seismic coastal areas are the study of the potential of liquefaction phenomenon in saturated sandy soils and seismic structure-foundation-soil interaction (SSFSI). Control of structure damage on the liquefiable soil and large deformations of soil due to seismic loading and, also, the other responses such as: the accelerations at top of the structure/foundation and excess pore water pressure related of this phenomenon are very important. The phenomenon of liquefaction happens due to the occurrence of an earthquake and due to the lack of sufficient opportunity for drainage of excess pore water pressure. One of the effective and useful mitigation methods to control of the liquefaction phenomenon is the usage of dense granular column (DGC) in appropriate dimensions and distances on the ground susceptible to liquefaction. The role of the DGC in controlling the liquefaction phenomenon are follow as: firstly, the DGC is made of materials that are more permeable to sandy soils and cause the excess pore water pressure to be dissipate faster, and secondly, DGC increases the stiffness of the system, which proportionally reduces the excess water pore pressure due to the dilative behavior. To reduce the risks of liquefaction, it is necessary to fully understand its consequences. These consequences depend on permanent soil displacements, structural performance, structural characteristics, foundation and structure dimensions, soil conditions of the structure site, type of loading and earthquake intensity. The presence of the structure and impact of SSFSI affects the intensity of liquefaction and static and dynamic stresses in the soil. Most prior studies (e.g., physical, numerical, or analytical models), ignore the existence of the structure or consider the effect of soil-structure interaction (SSI) on the liquefiable soil layer as an equivalent model. Hitherto, the essence and extend of these interactions are not sufficiently understood. These methods can not properly assess the damage caused by liquefaction; Therefore, these methods cannot be used in the design of structures resistant to liquefaction. Therefore, to accurately study the effect of liquefaction, a method and model is needed that can fully consider the soil, foundation, and structure so that it can be used to correctly estimate the amount of subsidence and displacement of the structure. In this study, to evaluate the seismicity and the mitigation effect of DGCs, using OpenSees finite element software, modeling of DGCs and surrounding soils without structure and models with 5, 10 and 15 storey structures were performed. The three-dimensional soil and DGCs modeled in the software are placed under different earthquakes and the effects of structural layers on the lateral displacement, excess pore water pressure, response of acceleration spectrum, drift and shear force of stories are investigated. The liquefiable soil is modelled through the pressure-dependent multi yield surface soil constitutive law (PDMY02) applied in OpenSees. The results of this study are shown the positive effect of DGC on the reduction of lateral displacement components of soil and structure, foundation subsidence and excess water pore pressure. Also, the presence of the structure on the soil and the increase of its floors have increased the mentioned components except for lateral displacement of soil.

Informal settlements in cities are one of the most vulnerable regions to natural disasters, including earthquakes. The investigation of the vulnerability of Tehran's 20th District to earthquakes revealed that the plans and measures taken to make this area more resilient were unsuccessful. This research was conducted to systematically identify and analyze the key drivers effective on the resilience of District 20 of Tehran against earthquakes.

The present study was mixed (quantitative-qualitative) with an analytical-exploratory nature, and the statistical population consisted of a group of 35 experts in the two fields of "futuristic approach" and "resilience". The Delphi technique was utilized in this research, and the obtained data were analyzed in MicMac software using structural analysis.

The findings obtained from the distribution of variables in the axes of influence and dependence of factors in MicMac software indicated the instability of the system within the scope of the study, based on which, five categories of variables were identified.

According to the high score of direct and indirect influences of the factors, 11 main factors were identified as the key drivers affecting the resilience of District 20 of the Tehran metropolis against the earthquake

Problem statement:

  Various estimates have been presented regarding effective strategies for reducing heat loss and energy storage in the body of traditional Iranian bathhouses. However, the efficiency level has not been determined due to the impossibility of calculating the function of each one.

This study attempts to the efficacy of three common strategies in the body of bathhouses, including “compactness in the texture and neighborhood”, “entering the ground” and “surrounding the apodyterium among unconditioned spaces” to see which is the most effective in preventing heat loss from the shell in traditional Kashan bathhouses.

The present study uses a quantitative paradigm and energy simulation strategy. In this study, Design Builder software was used for its calculations. It is based on evidence obtained from the physical reading of the spatial structure of traditional bathhouses in Kashan City. They were selected using a non-random sampling method.

Surrounding the apodyterium spaces among the unconditioned spaces in Kashan bathhouses has had different results which can be explained by their centrality in the bathhouse plans. However, in its minimum state, the space has been effective with a mean of 13.94% per year in Sultan Ahmed Bathhouse and 46.74% in Khan Bathhouse. This figure has reached 33. 18 percent compared to all four bathhouses. It shows the significance and efficiency of this strategy compared to the insignificant efficiency share of the strategies of inserting the bathhouse inside the ground and “compact urban texture to use the neighborhood” with values of 5. 44 and 0.6, respectively.

Introduction :

The urban landscape, whether as the internal or external constituent elements of the city façade, is considered one of the indicators based on which the quality of the city is assessed and judged. The visual and physical qualities of the urban space, as a place where citizens attend, play a significant role in promoting vitality and belongingness in the environment. Among various items, the order and proportions of the constituent components of urban walls and facades increase the abovementioned qualities in urban squares. Order and harmony, in addition to structural diversity, can be effective in forming visual and physical identities of urban walls. Their influence is enhanced by the repetition of design principles and the ingrained rules like proportions and geometry used in the historical buildings in the context. In other words, to connect the appearance of the newly built spaces in contemporary cities to the physical identity in the historical body of authentic places, it is required to read and perceive effective and appropriate physical rules, measures, and orders applied in authentic places. Associating and repeating the proportions used in authentic facades and walls in newly built ones can help to create legible, diverse, and beautiful platforms. As an example, one can refer to Imam Khomeini (RAH) Square (Tūpkhāneh Square), as one of the most important and oldest urban government squares in Tehran, where, despite many changes made during its historical course (from the Nasseri period to the Pahlavi II period), many commonalities have been used in its design. Therefore, the present research compares the geometric patterns and proportions used in the walls of this square in three periods (the Nasseri, Pahlavi I, and Pahlavi II periods) with emphasis on the architectural changes and developments that occurred in Iran from the Nasseri period to the present era. In addition to the identification of common and repeatable elements in the physical evolution of the square body, this comparison can also present solutions for contemporary designs.

The present study is applied-developmental mixed-method research carried out using an interpretive-historical approach. In the quantitative part, the quantitative characteristics of the length and proportions are investigated and the qualitative addresses the content affecting the façade. For this reason, the present research has a mixed nature, whose quantitative aspect is preferred to its qualitative aspect due to its emphasis on the proportions more than other main effective factors. Through the interpretive-historical approach applied, the required data were collected from pictorial documents on the case study, as indicative and inferential evidence, and then, from secondary documents and through observations to strengthen the validity of the research. So, drawing methods were applied to show the geometric proportions applied in the square in all three historical periods studied, and analyze the obtained data and calculated aspect ratios. To this end, the facades and walls were drawn, the aspect ratios of the components of the facades and walls were compared with those known as Iranian-Islamic aspect ratios, and the frequency of each was shown.

In the first period studied (Nasseri period), the most widely used aspect ratios in the main geometry of the facades as well as the openings in them were √1, √5, and √7, respectively. Regarding the aspect ratios used in the outstanding buildings on each facade, such as the entrances of Bab Homayoon Street and Nasseri Street on the southern facade of the square, the aspect ratio of √2 or 1.414 is the most frequent one. In addition, the facade of the Imperial Bank of Persia on the eastern side shows an aspect ratio of √3, which is one of the Iranian-Islamic aspect ratios. In the second period studied (Pahlavi I period), the application of golden ratios of Iranian architecture, i.e., √3 and √2, has increased significantly, which is obvious in the changes in the buildings constructed around the square during the transition from the Qajar period to the Pahlavi I period. Although one can see some features of Western architecture and culture dominating the external structure of the walls of the square, including municipal and telecommunications buildings in the north and south walls, and the Imperial Bank of Persia in the east wall, the geometric principles and Iranian-Islamic aspect ratios have been preserved as the representatives of the identity and originality of the square. It should be noted that the aspect ratios of √1 and √5 are observed in the Nazmiyah building, and the Imperial Bank of Persia, the aspect ratio applied in the previous period, i.e., √5, was preserved, despite major physical and formal changes in it. Also, in the telecommunications building, the aspect ratio of √7 is dominant, according to which one can explain that in the Pahlavi I period, the aspect ratios applied in the facades of the buildings around the square were all influenced by Iranian-Islamic aspect ratios and based on irrational numbers. In the third period studied (Pahlavi II period), most lines and elements used in the facade appeared without any specific aspect ratio and logical reason, and sometimes accidentally, indicating the arrival of a pattern with no identity and cultural validity into the square’s architecture. Looking at the architecture of the Tūpkhāneh Square in the studied third period, which coincides with the end of the Pahlavi II period and the beginning of the Iranian Revolution period (the present era), one can find that due to the arrival of modernism and its consequences, the importance of proportions and geometric relationships in the architecture of buildings has been gradually reduced. However, the existence of the buildings from the previous eras shows the aspect ratios applied in buildings during them to some extent.

According to the abovementioned, it is clear that proportions and geometric relationships are considered among the most important factors forming the facades and walls of urban squares. In addition to defining the identity and originality of urban spaces, they influenced their environment and visual quality. Therefore, the physical identity of Imam Khomeini (RAH) Square can be read and perceived only by relying on the physical order and harmony in its walls. The order and proportions (aspect ratios) used in the facades of the surrounding buildings represent the evolution of the square during various periods. Although the walls and façade of the studied square have experienced many functional and temporal changes during historical periods, the historical continuity of the durability of the buildings has shown a remarkable and significant effect of the studied indicator, which would continue for several decades. The structure of the walls of the buildings around the square in the first (Nasseri) and second (Pahlavi I) periods indicates the existence of a specific proportional system in all parts of the facade. The origin of such order and coherence in the buildings constituting the facades of urban squares can be found in the mental structure of the architects and masters of those times. It is a factor that was gradually forgotten in the architecture of the buildings around the squares in the subsequent periods.The results show the various and scattered presence of Iranian-Islamic aspect ratios of √1 (square), √2, √3, and √5 in the components and overall structure of the façade of Imam Khomeini (RAH) Square on its four sides in all three historical periods studied. Such order and harmony were associated with the greatest and most diverse compositions in the first and second periods studied, respectively, while in the third period studied, they gradually decreased due to the “change in the construction pattern” and “increased height of the surrounding walls”.

 SARS-CoV-2 may affect vital organs. The present study investigated the histopathology of pulmonary and cardiac tissues with clinical correlation in deceased patients with COVID-19.

 We obtained pulmonary and cardiac tissues from 30 deceased patients with COVID-19 in Tehran, Iran, from January to May 2021. Sampling was performed through a percutaneous needle biopsy. After slide preparation, two expert pathologists studied them. We assessed the correlation between clinical and pathological data by Fisher’s exact test.

 The mean age of the patients was 73.8±13.4 years, and the male-to-female ratio was 23/7. The most common underlying disease was hypertension (HTN) in 25 patients (83%). Fifty-five tissue samples were achieved, including 28 pulmonary and 27 cardiac samples. Our results showed that all patients (100%) developed diffuse alveolar damage (DAD), and 26 (93%) developed hyaline membrane formation. The most common phase of DAD was the exudative-proliferative phase in 16 (57.1%). Three cardiac samples (11%) revealed myocarditis, and seven (26%) showed cardiomyocyte hypertrophy. In univariate analysis using Fischer’s exact test, myocarditis had significant relationships with C-reactive protein (CRP) levels higher than 80 mg/dL (P=0.008) and elevated cardiac troponin levels higher than two-fold (P=0.01).

 COVID-19 can affect the major vital organs. However, only myocarditis had a significant relationship with the circulating levels of inflammatory factors.

One of the criteria for public judgment on the effectiveness of contemporary architecture education in each country is the suitability of the quality of learning of people according to the work environment of their academic field. It is important to understand the fields of employment in the field of architecture. This issue helps that educational topics in the fields of knowledge and skills have a better fit with the job position. This concern requires qualitative and quantitative analysis both in the way of presentation and in lesson planning. This research, with a practical and developmental purpose and descriptive-analytical in nature, uses the qualitative research method with a logical reasoning approach. For this purpose, the researchers use a pairwise analogy of skill-specialized parameters of architectural employment and hierarchical analysis to measure the frequency of courses and the weighted frequency of the criteria. This point makes the program unable to be responsive to the environment and it is not one of the subjects in the curriculum required by the graduates. In addition, the educational rigidity has caused no change in architecture graduates. This competition is visible with the majority of graduates in limited fields.

Knowledge and information science specialists can succeed in creating and providing entrepreneurial services by using knowledge of the society, the needs of the audience and having an entrepreneurial attitude. In the field of knowledge and information science, entrepreneurship is a type of social or value entrepreneurship service. Accordingly, the purpose of this research is to investigate the effect of entrepreneurship education in changing the entrepreneurial attitude of public library librarians in Birjand city.

The present study is a type of applied research. In terms of data collection, it is a quasi- experimental study with a control group, a pre-test and a follow-up test to determine the duration over times. The statistical population of the study included 30 librarians of public libraries affiliated to the library of the city of Birjand; Data collection was done by Entrepreneurship Attitude questionnaire (Robinson et al., 1991) and SPSS software was used to analyze the information collected through the questionnaire.

The results of the tests showed that entrepreneurial training has led to a shift in the attitudes of librarians in the test group, and entrepreneurial training has led to a shift in the orientation of self-esteem, Succession, innovation and personal entrepreneurial control of the group librarians and the post-test scores of the two control and experimental groups were reported differently (F = 5/568, P > 0/05). The average of librarians’ desire for success in the post-test stage (M = 4/528) has changed compared to the pre-test stages (M = 4/313). Also, the test of the repeated measurement design, which included librarians in the experimental group in the follow-up stage, showed that that the change in the orientation of personal entrepreneurial control of librarians has become significant, which has caused stability and stability in them. Self-esteem components such as confidence in one’s ability, confidence in work results, ability to solve personal problems, ambition and self-belief can be influenced to a large extent by changing librarians’ views due to the increase in the level of advertisements and their knowledge about entrepreneurship.

Originality/value: 

The current research considers entrepreneurship in public libraries as a great opportunity for managers and librarians. Considering that entrepreneurship can be acquired in libraries, librarians can use the benefits of entrepreneurial training to raise their level of work and provide entrepreneurial services to users. According to the goals and social roles of public libraries, entrepreneurship training in the society of librarians and users should be considered and implemented as one of the special requirements based on the goals and functions of these types of libraries because entrepreneurship training causes a change in the direction of personal entrepreneurial control of people and increase the amount of their personal control.

Statement of the problem: visual pollution in the informal sociable environments of contemporary commercial places, while reducing the physical quality of spaces and social interactions, can lead to irreparable damages due to the lack of awareness of the users of being in a polluted area and the immeasurable glare, inappropriate contrast, or the presence of direct light. be made This issue is more critical in commercial food courts, which in the last decade have had a high share of attracting the audience and creating human connections due to the nature of pauses and stops similar to comfort spaces. The purpose of the present study is to evaluate the design of the environments in question and especially the environments with the potential to pause for customers in the commercial building, focusing on identifying the points and conditions that aggravate visual pollution, conducting research in three examples of informal collective spaces in commercial-office places in Tehran. has doneResearch The current research is practical in terms of its purpose, which is applied-practical research in terms of the exploratory view of identifying the problem of the spaces in question. Also, in order to measure the current situation based on mathematical models and photometric evaluation of space, it is causal-experimental mixed research from the point of view of nature and method. The method of collecting information in this research is field due to the need for visual perception and environmental photography, and in order to choose more suitable spaces for measuring glare, non-random sampling has been used as described above. For this purpose, the intensity of illumination is analyzed with the help of the luminance spectrum resulting from the dynamic imaging of the Lupine meter software during photography.The spaces studied in the research were three food courts of Shemiran Center, Seven Center, and Sam Center in Tehran during the period of using artificial light (after sunset) which were chosen non-randomly due to the spatial characteristics and availability of access to collect the necessary data. . The effective components of artificial light disturbance are displayed in each of the samples. As mentioned before, in addition to the light source, its type, and arrangement, other environmental factors such as materials are important in terms of the present reflective effect. In order to estimate the amount of reflection of materials, the dominant materials in these environments, such as metal, cement, glass, stone, plaster, wood, brick, and concrete, are numbered and displayed in percentage calculations. Comparing the analysis performed by Lupine Meter software, it was observed that generally spotlighting, especially spotlighting on the bright surface of the ceiling or walls, causes maximum glare in direct or peripheral view due to the functional enhancement of light with background reflection. On the other hand, after spotlighting, transparent surfaces and windows with a high reflection coefficient caused more glare when faced with inappropriate lighting angles.Also, based on the points made in all three food courts, it was found that glare and light pollution are more in the parts related to the central parts and less in the corner parts. This importance has also shown the maximums and minimums of the evaluations by intensifying the transparent walls in the centers and the cloudy walls at the edges of the space.These results, while confirming the importance and priority of "material type", "polished material reflection coefficient", "color", "installation angle", "arrangement" and "chosen lamp and light type" in previous research, intensify the factors and their synergy in Showed together.It is obvious that the current research has been carried out due to the limitations of studies on the basis of artificial light and the hours of field harvesting after sunset (no use of natural light) as well as the establishment of the space of the selected food courts on the fourth and fifth levels and regardless of the external artificial lighting of the background. This issue can be considered for future research. Also, as mentioned at the beginning of the article, the present research was formed with the aim of improving the environmental quality of sociable spaces in commercial-office buildings, which can be measured and compared in qualitative methods and based on the perceptive votes of the audience.

Using visual signs in the design and architectural landscaping of the scene in the Marvel cinematic universe creates the concept of the place and brings metaphorical and implicit messages during an adventure story. Considering the semantic concepts and ideas of architecture and the development of design methods in the contemporary period, this topic can create a proper connection between the identity-building elements of architecture and the identity-giving scenes of the superheroes of the story, while expressing the story powerfully. This study was an attempt to identify explicit and implicit signs in processing and measuring the compatibility of common architectural indicators in buildings related to the superheroes of the story and characterizing the content of Marvel cinematic universe. Thus, the primary question of this study is what is the compatibility of architectural signs in story scenes with the characterization of Marvel superheroes?  For this purpose, the present study’s method is descriptive in nature and relies on content analysis in a qualitative-interpretive paradigm and semantic and linguistic semiotics. It tries to read the meanings and metaphors, and the implicit link in the ideas and concepts of design in the housing building or the primary centers of activity in Marvel cinematic universe. The results show that each superhero created by Marvel, with a unique personality and special abilities, takes its own story path. In this regard, based on the characteristics that the writers have created for the afore-mentioned characters, in addition to the synergy of people together, formal, functional, and conceptual commonalities can be seen in the emergence of the design concepts of the houses of Marvel superheroes and their primary activity centers. This issue has been changed to some extent by the differences and the unique characteristics of each character or place by referring to adjectives such as "breeze and brave", "powerful in the sky", "hidden and powerful", "optimal and efficient", and having "power", "speed", "boldness", "flexibility", and "having high knowledge and intelligence". Therefore, while maintaining great diversity, the common activities of the characters have helped form a certain identity.

The current study aimed to investigate the mediating role of psychological empowerment in the relationship between perceived social support and entrepreneurial spirit of undergraduate students at the University of Birjand. The research method was descriptive-correlational, and the statistical population included 8,304 undergraduate students at the University of Birjand. A simple random sampling method was used to select 380 students. The Zimet et al. (1988) Social Support Questionnaire, Spritzer and Mishra's (1995) Psychological Empowerment Questionnaire, and Vatan-Khah and Rezaeimoghaddam's (2015) Entrepreneurial Spirit Questionnaire were used to measure perceived social support, psychological empowerment, and entrepreneurial spirit, respectively. The content validity of the questionnaires was confirmed by experts, and their reliability was assessed using Cronbach's alpha coefficient. The structural equation modeling showed that when perceived social support was considered as the predictor variable and entrepreneurial spirit was the criterion variable, the model had a good fit and the relationship between the components of perceived social support and entrepreneurial spirit was significant at the level of 0.05. The findings regarding the mediating variable indicated that psychological empowerment played a mediating role.

Leisure activities are an important part of life for people with multiple sclerosis )MS). Unfortunately, there are no proper assessment tools for evaluating the leisure activities of MS patients. The current research purposed to develop such a questionnaire and to determine its factor structure.

This psychometric study aimed to determine the factor structure of a questionnaire for evaluating the leisure activities of MS patients and was conducted in explanatory and confirmatory phases.

The questionnaire was completed, and the data were entered in SPSS for the explanatory phase and using linear structural relations (LISREL) for the confirmatory phase. The lowest Eigenvalue was 1.01, which corresponds to the Kaiser criterion. The validity coefficients of the extracted factors are considerable. There is a very slight difference between the highest coefficient thatis related to the third factor (0.846) and the lowest coefficient that is related to the fifth factor (0.799), indicating the number of factors was correctly determined. Confirmatory factor analysis illustrated that the goodness-of-fit (GFI) and the comparative fit index (CFI) indices were considerable (higher than 0.95),showing good fit of data. RMSEA was 0.024.

It can be concluded that the 5-factor structure (difficult, social,spiritual/religious, outdoor-physical, and cultural-artistic activities) of the multiple sclerosis leisure questionnaire with 50 items is confirmed.
