Urban land utilize planning, for optimal use of existing facilities and urban spaces is one of the main cores of urban planning, which is usually defined as a multi-objective issue. In line with the absence of specific categorization, system for land use in Iran the use of metaheuristic algorithm and artificial intelligence is required. One of the algorithms that introduced and used in recent years are the optimization algorithm (BBO) based on biogeography. Current research is from practical research group and type of descriptive-analytic research, the data analysis method would be write and execute in MATLAB software by using biogeography algorithm. The purpose, after identifying most effective variable, will be to improve the present status of the system's distribution use indicators and their adjacency in the county surface. For comparing the results of current research, in terms of desired area needed uses with development plan of Semnan County, each dimension of (GIS) layer should be provide.overlapping of the layers would be compare with development design.

Promoting urban livability and realizing a livable city are closely linked to how the urban management apparatus and institutions and organizations active in urban affairs function. Municipalities, as the most important coordinating body in urban affairs, have played a decisive role in solving urban problems and are responsible for the social and physical development of cities. In fact, municipalities have the main task of serving the citizens and play the most important role in improving the quality of life of citizens. The purpose of this study is to evaluate the viability level of Semnan city and analyze the problems of Semnan city from the perspective of different groups (officials-elites). The research method is descriptive-analytical and the research tool is a questionnaire. The validity and reliability of this research has been confirmed by the previous similar research and the opinions of the supervisors and advisors of the dissertation, the validity of the research tools. The internal validity of the instrument (questionnaire) is also shown through the Cronbach's alpha with a value of 0.84 for the questionnaires. The results showed that among the total biomarker indicators of Semnan city, from the point of view of elites and officials (with an average of 2.76), it was evaluated at a low level. Also, based on prioritization with ANP technique, "Improving Institutional-Organizational Capacity in Optimal Urban Management (R7)" with the highest score (07/357: 357) was identified as the best solution and in fact the main solution to deal with urban issues in Semnan. Also, the strategy of "integrated management between urban organizations to coordinate in the management of urban affairs (R6)" with (06/3366) was selected as the second solution.

Today, the process of developing and constructing educational spaces tends to be more inclined to physical dimensions and is painted against human beings and their characteristics. The result is a disconnect between the students' relationship with the schools in particular and the educational environment in general. As such, they consider their students to be less part of the high school and feel less attached to it. The purpose of this study is to focus on designers 'view of the semantic levels of the school environment that can influence students' sense of place. The research method was descriptive, analytical and survey using spss software and Lisrel 8.8. This study uses the confirmatory factor analysis technique to determine whether the number of factors and loads of variables measured on these factors are consistent with what is specified in the theory. According to the results of confirmatory factor analysis, the standardized coefficients are acceptable and relatively large. Through the SEM structural model, it was estimated that the highest correlation and consistency between subjective factor with factor loadings of 0.76 and physical component rank second. With a factor load of 0.63 and finally the educational component with a standard coefficient of 0.58 establishes and promotes a sense of  belonging in high schools. At the end of the conceptual model the research was mapped using structural equation modeling and by regression it was concluded that subjective, physical and educational components predict 43% of the variance in sense of belonging in Tehran high schools.

In today's urban planning, the paraphrastic processes of symbolic systems in the city, which aim to show the social and cultural meaning of the physical environment, have received less attention, and most urban contexts, regardless of significant and identifiable differences and similarities and the hidden values in the context and the patterns of traditional urban planning and architecture of Iran are formed, and this makes it important to analyze these processes. The object of this paper is to present a framework for considering change of semiotics system caused by factors affecting the urban identity and comparing these systems in the old and new textures of the city by layered attitude toward the city as a multimedia text. The research is qualitative and the method of research is descriptive-analytic analytic and Semiotics has been used as a tool and method for considering representations and analyzing the identity of the city. Studies in the old context relied heavily on documents and in the new context is field and the samples were studied in hot and dry areas of Iran.The results show that based on the study of representations in the symbolic system in the textual layers of the city form, the duality of meaning and identity of the old and new textures of a city over time indicate several main factors of change within the textual layers of the form of city, the rupture and duality in the human layer and change in the system of codes that affect the structure of the city form, which is manifested in the elimination, replacement or change of signs in the natural, social and artificial layers.

The present research has been carried out to analyze the behavior of the rural community of Varzaqan in the territory of electoral geography and the approach used in it is "spatial-behavioral". Research based on the purpose is practical and in terms of collecting data, it's a mixed type (exploratory design - tool development model). According to the research goal, using the qualitative method, through the phenomenological method, the deep understanding, complexity, detail and texture of the studied phenomena have been studied. Then, using this initial identification (in order to arrive at a generalized result), it was attempted to develop the tool using the SEM. Using a targeted sampling method, the sample size of the first phase is 25, and for the second phase, 32 people are localized. Phenomenological results show that the Electoral Behaviors of rural community in Varzaqan county can be analyzed in three main categories: (a) "geographic features" with the themes of "sense of location, neighborhood impact, and localism"; (b) "individual and social" with the themes of "social stimulus and individual stimulus"; and (c) "political" Themes "Engagement Conditions, Affective Role, Political Orientation, and Religion." This behavior is in accordance with the categories of "geographical and political characteristics" with the "rational choice theory", and in terms of "individual and social" with "the pattern of political economy (wise reformed approach)". Modeling results also show that the variable "geographical features" and "individual and social factors" are at the "significant" threshold and the variable "political factors" is within the "average" threshold; The quality test of the structural model shows that "political agents" and "social factors" have "strong" values and "geographic features" have average values to determine the predictive power of the electoral model.  The general model of the SME shows the goodness of fit in the model and shows its generalizability.
