The shore flies (Ephydridae) are a relatively large family of acalyptrate Diptera and are often prominent members of aquatic and semi-aquatic environments. Adult shore flies can be found in moist conditions, such as the borders of marshes, wetlands, lakes, pools, streams, and seashores. In the systematic and ontogenic studies of the Diptera order, the structure of the larval stages is of great importance. However, there is limited information about the body structure of shore fly larvae compared to that of adult insects. Despite their diverse morphological compatibility, the order Diptera provides many examples that contribute to our understanding of larval evolution. The aim of this study is to describe the morphology of the larval stage of the shore fly species belonging to the genus Ephydra sp. using light microscopy (Nikon Eclipse 50i, NY 11747-3064, USA with camera Digital Sight DS-L2, Nikon, NY 11747-3064, USA) and Binocular Stereo Microscope (SMZ171). The study will enhance our knowledge about the larval stages of the Ephydridae family in the Gomishan region (Golestan province), which is being reported for the first time. The importance of conducting specialist studies is emphasized in order to diagnose species using genetic and molecular methods in the future.

The present study was conducted in order to monitor the water of the reservoir behind the Boostan Dam using the phytoplankton population and Palmer index for one and half years. The sampling was done seasonally in five stations from depths of 0.5 to 3 meters using One-liter Ruttner sampler. After identifying phytoplankton species; the Shannon-Wiener diversity index, Margalf richness index, Simpson index, Pillo's species uniformity index, and also Palmer's pollution index were determined. According to abundance, 5 phyllums were the dominant phytoplankton groups; Bacillariophyta (56%), Chlorophyta (23%), Cyanophyta (13%), Euglenophyta (4%), and Pyrophyta (4%). In this area, the Shannon-Wiener diversity index showed an average level of biodiversity. The highest value of the Pielou (0.88) and Simpson (0.95) indices were obtained in the summer. The lowest value of the Margalef index was calculated in the summer with a numerical value of 2.82. The results of Palmer's index showed that the water of reservoir behind the Bostan Dam is categorized at the level of very high organic matter pollution.

The lakes behind the dam considered as semi-natural resources and have a special role in aquaculture. In order to achieve management goals, it is necessary to know the pattern of changes in biotic and abiotic parameters in the lake behind the dam. For this purpose, in order to determine water quality using water quality indicators (WQI) 12 physicochemical properties (water temperature, dissolved oxygen, salinity, acidity, electrical conductivity, suspended solids, total hardness, total alkalinity, nitrate, ammonia, phosphate and phosphorus Total) was evaluated in 2018 on a monthly basis for one year at 7 stations of Golestan dam in Gonbad city. Although temporal and spatial changes observed in some measured factors; According to the WQI index in Golestan Dam, it was relatively average to good in different months. Therefore, it evaluated as favorable for the breeding of tropical and subtropical fish.

Architectural design has grown alongside the expansion of digitalism's aspects, and design initiatives are the product of several collaborations, interactions, and nodes. Focusing on an architectural competition as a case s tudy, this article demons trates how the architectural design process works by highlighting the characteris tics of a network produced by the assemblage between heterogeneous nodes. These assemblages could modify every design phase and outcome according to their s trengths and weaknesses. Therefore, the socio-technical aspect of the design process is used to demons trate the reciprocal relationship between nodes as humans and nonhumans. This paper uses a qualitative approach by using the methodological aspect of actor-network theory to map the intricacies of the design process from three independent narrations to give complementary components to form the design process's multiplex network. Thus, the s tudy proposes a paradigm for exhibiting and grasping the complex data network in architectural design and boos ting the value of unseen data that may significantly impact outcomes.

Rapid design and reconstruction after natural disasters and rapid changes in materials and construction technology are among the factors that play a role in the disruption in the stability of the country's rural environment and also leads to the loss of rural architectural identity. And the factors affecting sustainable rural housing in the mountains. The present research method is descriptive-analytical and survey type. The statistical population of the study is the population of 20 villages equal to 6289 from Varzeqan and Harris counties. The sample size included 322 people obtained from Cochran's formula. The sampling method is simple random. Cronbach's alpha was used to evaluate the reliability of the questionnaire. To test the research questions, first the normality of the data was examined using the Kolmogorov-Smirnov test and after confirming the normality of the data, the second-order confirmatory factor analysis was used. Calculations were performed in SPSS and Amos software.Based on the findings, the good fit index (GFI) is 0.915, which indicates the acceptability of this rate for optimal fit of the model. The root mean square of the estimation error (RMSEA) is 0.065, which is acceptable due to being smaller than 0.08 and indicates the confirmation of the research model. Also Tucker-Lewis index (TLI) 0.906; The adaptive fit index (CFI) is 0.903 and the normalized fit index (PNFI) is 0.71, all of which indicate the desired fit and approval of the research model. The results show that physical, environmental, economic and social factors in the region are effective in the sustainability of rural housing and among these factors; Physical index had the greatest impact on the stability of rural housing with a factor load of 0.92. The social index has the least impact on the sustainability of rural housing with a factor load of 0.81.

Research Problem:

 Design research is the field of dealing with content and procedural areas. Architectural design is the result of assemblage between diverse actors. The advent of technology-driven procedures has broadened the range of actors in the design process. This has led the balance of the share of designers and technical objects in the final result of the design disturbed. With the advent of technology-based procedures, machines are playing substantial roles in design and hence, changed the way designers face architectural challenges. Accordingly, it seems that the current design process has shifted from a reciprocal relationship to a spiral movement in which the role of each actor can be analyzed as an actor in the multidimensional network of design. Consequently, the design procedure would be analyzed as a network of actants. The actor-network theory, as a result, provides an approach to analyze events in the design process and is profoundly applied as a methodological tool. Every detail in the design process is like an actor who changes the course of the design. Therefore, the main problem this research is going to undertake is to explain how the actor network theory works in clarifying the role of actors and their impact on the collective design process.

Research Question: 

The main objective of this research is to enlighten the essence of actor-network theory as a research methodology and tries to find the answer to the subsequent questions: How to analyze the architectural design process with actor-network theory and how does this theory influence designers’ interactions?

 The current research is applying design research methodology in a qualitative approach and tries to explain actor-network theory as a research method in architectural design. A practical experiment is demonstrated due to actor-network theory and socio-technical diagrams were qualitatively described.

 The networked nature of the design process has enabled research studies to investigate the design process by actor-network theory. The analysis of the experiment (architectural competition) revealed that connections of nodes in the network were not hierarchically observable and they had a hybrid characteristic. In this sense, non-human existence in the design process was inevitable. The results of the analysis also revealed that collective design can be network-oriented if, in addition to being valuable among human actors, it accepts non-humans in an influential position. Such a design has a very mixed atmosphere and any (unforeseen) event in it can change the design process like an action. Human and non-human actors must actively participate in the design process to stay in the network. Finally, not only the contribution of the actor-network theory in the identification of the design network was revealed, but also it facilitated the analysis of nodes’ connections. Thus, in answer to the research questions, it should be acknowledged that by using actor-network theory in the analysis of the design process, the black box of design could be opened and with a new composition, design actors could be expressed in a socio-technical way so that designers, users and technical objects have an equal and interconnected role. This provides a new reflection of the links in design process and makes a unique narrative of design to each project. In addition, the role of the actor-network theory is to track actors, highlight links, and provide unseen details in the design network. Moreover, it also changes the way designers deal with design issues; as designers with a socio-technical approach would advance the design process in the context of networks and use any event as an opportunity to intervene in the design process.

Abstract
Problem statement: The structure of today’s architectural education and the doctrines presented in this system have tried to figure out how to build the body of architecture and how to create architectural work. This trend, in turn, has led to the authority of fabricated formations and the narcissism of contemporary man. Architecture is a local phenomenon the roots of which must be traced to the folk and their lived experiences. As such, this article seeks the lived doctrines of Hafez’s poetry and phenomenology of the impact of these experiences on the process of learning architecture.
Research This study aims to understand and reexamine the lived experiences of human beings in relation to the reading of Hafez’s poetry to promote humanizing doctrines in the process of learning architecture.
Research This study is qualitative research, employing a phenomenological method and Van Manen’s approach (a descriptive-interpretative approach). Here, we seek to investigate the internal and intellectual doctrines obtained from lived experiences of Hafez’s poetry through interviews with eight experts who were already acquainted with Hafez’s poetry in the fields of philosophy, literature, humanities, and architecture, In the research process, 18 doctrines were obtained. Then, through MAXQDA software the main themes were summed up and horizontalized.
Hafez’s poetry, as a “mediating space”, is a phenomenon that deals not only with aspects of humanization but also with the techniques for establishing extensive relationships with another phenomenon. The result of this study is presented in the form of a final model (Dayere -e- Mina), meaning human refinement and self- therapy to change the hegemonic attitude of static phenomena, how to teach human beings as well as rewriting architecture through Hafez’s lived experiences with a metaphorical language.

Problem statement: 

Architectural co-design has been facilitated through the development of digitalism. This has shifted to a new paradigm which has evolved the understanding of design process. As a result, design process has been changed in both technical and philosophical aspects and co-design, consequently, has acknowledged The Other in the design process. Accordingly, design is formed by interaction of at least two simultaneous networks.

This paper aims to focus on design as a socio-technical process by analyzing dimensions of actors, quality of network dialogue and the process of network in co-design.

The Actor-Network Theory is applied to study the actors of co-design process. The quality of network dialogues is examined by analyzing texts and different types of networks and their impact on design process are determined by comparing two co-design cases. Thus, the paper is using a qualitative approach to redefine each node in the design process.

Different actors, human and non-human ones, shape the overall interactions of co-designers. Using network approach as a theoretical base for this interaction, revealedorstd four main elements in the design process: acceptability of The Other, criticism-tolerance, sharing personality, and collective intentionality. On the other hand, results from the two co-design case studies demonstrated insights on socio-technical approach of design and its impacts on other co-designer’s network relationship.

In accordance to the adaptation of architectural styles to the specific climatic conditions of the desert regions has led to the formation of an architectural style tailored to the needs of these areas. Understanding the coordination mechanisms of the technique, materials and environment and its intended application in understanding the concept of aesthetics and the performance of traditional buildings in the Iranian desert cities has attracted the attention of local and foreign researchers. In general, the concept of sustainability formed as a result of human awareness of environmental issues and socio-economic and cultural problems can be seen in desert architecture. One of the most important goals of sustainable development is to preserve nature and to alter the overall outlook towards it; furthermore, it is also sought to promote sustainable development in the built environment termed as sustainable architecture. Hence, the aim of this article is to understand climate adaptation and the environment response of traditional Iranian structures in the unique climate conditions of the desert. In this regard, this paper with a descriptive and analytic methods expresses this hypothesis that there seems to be a reliable and unique association between technique, structuring materials and environment with traditional Iranian structures built in desert areas. In order to prove the research hypothesis, first a descriptive and eloquent definition of the concept of sustainability in the structures and synergies created in the desert ecosystem and architecture is presented and then, the spatial features of a native desert architecture model after climate adaptation are described. Finally, it has been proven that the special features of architecture in desert areas have led to the emergence of beautiful traditional buildings appropriate to the climate of this resort.

One of the important issues in aquaculture is the confidence interval between the aquaculture fields under the different pollution loading conditions. one of these conditions is the instantaneous pollution loading. It is necessary to determine a confidence interval between aquaculture fields that the instantaneous pollution in one field doesn’t influence another field. Gorgan Gulf is one of the most important water resources and supplier of fishing in Iran. The goal of this study is the determination of confidence interval between aquaculture fields. In this study، 2-D hydrodynamic and salinity modeling of Gorgan Gulf using MIKE21 is performed. Salinity concentration was measured in 19 different stations during 5 months of 1390 and the hydrodynamic and salinity models were calibrated and verified using these data. The optimum values for manning and dispersion coefficients were determined 0. 025 m/s and 50 m2/s، respectively. Then، 6 different conservative instantaneous pollution point sources were exerted in the gulf and the salinity model was implemented. The peak of pollutant concentration in various distances from point sources was determined and compared with the initial concentration of pollutant in the point sources. The results demonstrated that 99. 9% of pollutants is diluted until to 100m from point sources. Hence، the confidence interval of Gorgan Gulf was determined about 100m.
