According to the resource based attitude, the capabilities of information systems improve firms’ performance and competitive advantages through three ways: 1) inside-outside capabilities, 2) outside-inside capabilities and 3) spanning capabilities. Because of the importance of systematic study on the relationship between these capabilities and firms’ performance this paper was aimed at investigating this relationship using fuzzy analytic hierarchy process (FAHP). We utilized the FAHP because of existing several indices, complexity of decisions and uncertainties that are intrinsically involved in the evaluation of these capabilities. The results imply that among the criteria, return on sales and cost of sold goods are two key criteria that facilitate firms’ success. Moreover, inside-outside capabilities regard a good stimulus for improving firms’ performance. Then, firms’ internal capabilities are more important in responding to market than outside-inside capabilities.

Earthquake is one of the major natural hazards which specifically makes cities of developing countries more vulnerable to probable earthquakes in comparison to developed countries. Tehran as the biggest and most populated city of Iran due to the active faults in the vicinity of it and its high population and constructional density has great vulnerability to probable earthquakes. The territory of Accessibility Network has a significant role in earthquake vulnerability reduction, so if the Accessibility Network can be ordered according to standard principal of urban planning, the vulnerability can be decreased. To obtain this purpose the environmental assessment is the basis element and there are lots of different methods and techniques. Present paper with emphasis to the studies in the observed field(Located in the 6th district of Tehran Municipality) and the presented conceptual framework, which is a composition of Analytical Hierarchy Process, Fuzzy logic, Network Analyst and Probability Function; analyses the probable vulnerability due to relevant factors to Accessibility Network in the case of earthquake.  The proposed model represents an explicit and intelligible frame based on the available information for the earthquake vulnerability assessment due to access base criteria. Using this model provides a proper and scientific basis for the accurate perception of access to these vital centers during and after probable earthquakes. The outgoing in the mode of map, chart and graph illustrate the resultant condition of parcels in the studied area. The produced vulnerability map can be used in site selections of these centers and vulnerability reduction programs by relevant organs such as Crisis Management Center, Emergency centers, Fire stations, Municipalities and etc.

One of the most important issues that have affected the basis of education during the last decades has been the realization of comprehensive objects of learning. In this way, emphasis has been mostly on instruction and not teaching, encouraging students to be independent and creative, regarding learning as a process, paying attention to how students learn, encouraging students to communicate with their teacher and others, and on the ground in which learning takes place. One way to reach such objects is to develop social schools in the framework of educational plans and a spatial background and frame proportional to those educational plans. In this study, we have tried to introduce functional indices proportional to community schools by a brief description of social schools and identification of spatial areas in learning environments. For this purpose, case and background research has been used and data have been gathered by referring to library and using case study. The result of this study is indicating the indices of exterior spaces and the manner in which each of these indices influences the process of fostering the skills and intellects relating to exterior environments. In addition to having multiple intelligences, each person possesses different talent or learning styles. While all human beings possess all of these intelligences in varying amounts, each person has a different intellectual composition. These learning styles can work independently or together. The learning environments that emerged in the twentieth century generally valued passive learning activities. Children who show talent in the active intelligences are not receiving the same positive reinforcement to encourage them to develop their learning styles. The theory of multiple intelligences can therefore help transform the way schools operate. The challenge is to create educational programs that give children the opportunity to learn in the ways that harmonize with their unique minds. In creating a learning environment that encourages the development of these multiple intelligences, teachers do not need to present their lessons and students do not need to learn the subject in nine different ways. Rather, this theory encourages teachers to develop their curriculum and present lessons in a variety of ways so that students will acquire knowledge and master skills in way that are appropriate for them.

By Looking at Iranian Contemporary Architecture and it's different generations It can be found that there are examples of excellence in architecture which Can be based on the characteristics and components of the Architectural Review, They to a specific stream architecture in Iran and Independent of the architectural approaches of the West, as an affiliate. This research is based on case studies, it followed up with an analysis of the signs and current thoughts available in the text architecture, to identify trends and approaches in contemporary architecture generations and answer to the question whether there is significant sequence in the concepts used by architects at different periods? It is assumed that the defining trends of Iranian contemporary Iranian architects from Iranian modernism to nationalist tendencies, Revitalization or classical market, while It can also work in conjunction with the value and importance of the historical context of the assessment, Explaining the origins and reliable indicators, Makes the flow of existing theoretical on Iranian history of contemporary architecture be recognized. Defining the correct position of Iranian Islamic architecture in the post modern world elicits various points of view. The increasing importance of literature related to linguistic philosophy, post-constructivism, cultural relativism, and the end of ideology has instigated a sort of mental inflammation in the community of Iranian architects. A pragmatism abstracted from the environment is one of the trends that have developed in this respect. Based on results of a comparative analysis of three generations of Iranian contemporary architects work, Also, according to the authors describe, It follows that the theory of contemporary architecture in Iran, Within four specific categories, such as The giver ideas, Aesthetic style references, Selection Form and types of materials can be explained. The analysis of these four components in architecture works explains that the giver ideas of posit has been followed with more persistent in the pursuit of different generations and over time in comparison to the other components has less changes. This perception can underline the existence of a common discourse between color, smell and Iranian structure that can be the missing detail of the Iranian contemporary architecture. Throw a glance at current Iranian architecture and its generation, it is realized that there are some preferable samples in this period which could be referred as a special stream in Iranian architecture and in depended from west approaches, based on the type of characteristics and architectural criticize components. Iranian current architecture is one of areas that has not been studied exactly and by analyzing works and current stream and it is especially referable. It is realized from rapid and also extreme changing of Iranian architecture that the trend to classical architecture has been changed in different situation. These rapid changes have been happened due to modernizing and mechanism that could be considered as modern period effects. Iranian challenges with contemporarily, in recent two centuries, was expanded in governmental and intellectual parties. In this era, extreme changes was happened in the most areas including architecture and provide different approaches and simultaneously some intent to classical thinking. This research, based on case study approach, followed analyzing the signs and streams of consciousness in architectures work contexts, to realize the approaches of current generation of architecture and also find the answer for a question about finding a reputable track record in the used concepts with architects depending their different periods. It is assumed that, specifying the definition of Iranian current architect’s trend, like Iranian modernism, nationalism, renovate or classical popular approaches, helps to recognize theoretical stream of current Iranian architecture with realizing and specifying roots and valuable indicators, and furthermore can assess the importance and worthiness of each work. Reviewing current Iranian architecture shows, in spite of various generations, the main concepts have not any diversity and its evaluation will be realized and performed with improvement of these concepts. Anyway, because of this subject that the attention to current Iranian architecture for finding a reliable classification, needs reviewing basic concepts like methodologies, forms and architectural studies, as the basis of the effective items like design ideas, design locations and frame works, design themes, spatial concepts, visual shapes and the used material, therefore we have to realize the hide vision of these three generations of architecture, considering right viewpoint, to provide a statement for classifying or finding a similar theme between Iranian and current world architecture. Based on the results of comparative analysis of three generation of Iranian architectural works, and also regarding the clear-sighted authors description, it seems that, the stream of theory in Iranian current architecture could be realized as a framework by four specific categories including structural giver ideas, stylistics refers, form selecting and type of materials. Analyzing these four categories in architectural works shows that the structural giver ideas have been followed by different generation with more persistent and have the minor changes than other categories during this era. This perception discovers a common thought in Iranian current architecture that can be the missed stream of it. The trends and ideas underlying a design are the main concepts on which the main design of a work of architecture is based on. Conceptually, the structural idea of a design is the main definition that architecture is based upon and in some literature, it is even viewed as a concept. Based on evaluation and analysis of the frameworks of the prominent works of Iranian architecture of three generations, mainly after the Islamic Revolution, structural ideas of architectural designs and the product of prominent Iranian works of architecture is a mélange of international and regional intellectual currents, the leading culture of the designs as they relate to their era and social, political,cultural and economical interactions. Furthermore, a deep review of contemporary architecture in Iran after Islamic reveloution, points out a lack of familiarity with main universal contemporary architectural theory, which is the main reason behind the architects, designers, professors and researchers of architecture, and most importantly, those who enjoy architecture.

In this study, the effect of carbon and nitrogen sources, on production of yeast biomass was determined as well as the efficacy of various formulations of Candida membranifaciens to decrease blue mold on apple. The media containing sugar cane molasses as carbon sources caused more yeast growth than the media supplemented with permeate powder. Yeast extract as nitrogen source produced higher biomass than urea and Corn steep liquor (CSL). The best growth was obtained in medium that composed of sugar cane molasses, yeast extract and CSL. Viability of C. membranifaciens differed in various carriers significantly (p < 0.01). The number of viable cells in Kaolin and Talc-based formulations was gradually reduced whereas the viability in wheat bran based formulations increased in 4 months and then gradually declined. In general, the formulations stored at 4 °C had longer shelf life than those stored at 24 °C. The antagonistic efficacy of prepared formulations of C. membranifaciens was evaluated against Penicillium expansum on apple at storage conditions. There were no significant differences among Talc-based, Kaolin-based and Wheat bran-based formulations of C. membranifaciens in reduction of blue mold.

Data and information play a special role in the transparency of water governance. On the other hand, witnessing contradictions in water resources data and information, inconsistent readings and narratives about water assets, outdated hardware equipment, and to some extent software enhancement in the preparation and presentation of water resources information compared to global advances, necessitates a serious review of water resources data collection and processing systems. In this regard, artificial intelligence methods, sensors, and remote sensing technologies are considered in accurate water resources accounting. This article is a systematic review of about 100 international articles that present the latest findings related to software and hardware equipment for monitoring hydrological cycle meta-indicators. These meta-indicators include precipitation, water depth/water level/flow velocity and discharge of rivers, and groundwater level. In each case, while providing a list of the most important technologies, the application level of these technologies in monitoring surface and groundwater resources in Iran was evaluated. The conducted studies prove the unfavorable application technologies in monitoring hydrological cycle in Iran. For example, out of a total of twenty-six known technologies related to surface flow measurements, only two technologies have been widely used Iran; four technologies have reached the knowledge frontier and widespread production by domestic knowledge-based companies, and eleven technologies have not yet reached the knowledge frontier Iran. In this paper, suggestions were presented to outline the path for developing new technologies for water cycle data collection and transformation in the modernization of Iran's water resources data collection and data processing infrastructure.

Backgrounds: Coronavirus disease 2019 (COVID-19) pandemic is considered as a global health challenge, and Iran is among the top ten countries with the highest mortality rate. This study aimed to analyze epidemiological, clinical, and laboratory features of hospitalized SARS-CoV-2 infected patients and identify the risk factors of mortality among them to facilitate the prioritization of resources and vaccine allocation in the population using data available in a large university hospital in Tehran, Iran.
Materials & Methods: From February 20 to May 14, 2020, a total of 684 COVID-19 confirmed cases were admitted to Imam Hossein University hospital in Tehran and enrolled in this retrospective observational study.
Findings: The mean age of the participants was 59.48±16.65 years, and 55.8% were male. Compared to survivors, non-survivors (n=127, 18.57%) were older (69.09±14.16 vs. 57.29±16.40), had higher average number of comorbidities, and more frequently suffered from dyspnea, convulsion, loss of consciousness (LOC), tachycardia, tachypnea, and hypoxia. They also had higher levels of leukocytes, neutrophil count, C-reactive protein (CRP), creatine phosphokinase (CPK), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), international normalized ratio (INR), prothrombin time (PT), partial thromboplastin time (PTT), urea, and serum creatinine (p<.05). Serum potassium (K), lymphocyte count, hemoglobin, HCO3, and serum sodium (Na) were significantly lower in non-survivors. Multivariable logistic regression analysis results revealed that nine variables were positively associated with mortality.
Conclusion: Among COVID-19 patients admitted to the hospital, having more than two or three comorbidities, loss of consciousness, SpO2 < 90%, increased CRP, CPK, urea, and serum potassium, were associated with mortality.

There is a continuous emergence of new technologies in modern society, and the most widely adopted are information technology. Today organizations perform business in a global and information enriched environment. They benefit from the existence of networks, such as the internet, that not only enable access to information, but are also a great means of communication. Relationships are one of the most important factors for the success of an organization. Expanding the use of social networks and social media has had a huge impact on both personal and professional aspects of life, so it is not surprising that organizations are sensitive to employees’ use of social media. In recent years a lot of research has been done on this subject, some of which has shown an improvement in job performance, while others imply a more negative impact. It is believed that employees' use of social media and its impact on job performance is affected by other factors that should be considered.
This research tries to prepare a comprehensive model to show both primary and secondary factors in the relationship between the use of social media and job performance. A questionnaire was used to gather the required information. The statistical populations' sample of this study included 227 employees of Tarbiat Modares University. The results show a significant correlation between personal factors and use of social media, social media and social capital, job satisfaction, organizational commitment and job performance.
