Until now, a major application of scientific methods has been to estimate and predict the values of a variable by referring to the values of one or more other variables associated with it. In this paper, we examine the most common type of "correlation", or estimation based on structural relationships between variables, which leads to the creation of a simple linear model. The use of linear models in a variety of urban analyses is quite commonly accepted due to the relative simplicity and accuracy of these models. Linear models usually show tendencies over time, which may not be taken into account through abstract or chart-based analyses. Linear models are used to express events when non-scientific methods are incomplete and unsatisfactory (and predict the appearance and time of the events).

Urban planning research, like most behavioral sciences and human research, should be supported by a proper theoretical framework or conceptual model. In this theoretical framework and conceptual model, the variables and factors affecting the subject matter are identified and their relationships are determined. To assess the validity and correctness of these models, there are different qualitative and quantitative techniques and tools. Structural equation modeling is one of these quantitative and multivariate tools that examines and evaluates the fitting of the model and allows for some modifications in the model. In this paper, along with introducing the technique of modeling structural equations and Lisrel software, its application in urban planning research is described.

The focus of the present article is on the effects of globalization on the structure of the cities of Islamic countries, and in particular the social, economic and physical structure of these cities. In this paper, after presenting an introduction to the process of globalization and its characteristics, the effects of this process on each of the above dimensions have been studied. One of the most important effects of globalization on the social structure of cities of the Islamic countries referred to in this article is the separation of the sacred space (Lahuti) from the unholy space (Nasuti) in the Islamic cities and, consequently, the loss of the integrity and unifying quality of these cities. The effects of globalization in the economic structure of Islamic countries can be summed up in issues such as dependent economics, an unequal relationship of the center- around type to the metropolitan western cities, single-product economy, dual economy, and severe class inequality. Changes in the physical structure of Islamic cities through the process of globalization have also been examined in general in two separate categories: the changes that have taken place in the natural elements and environment of these cities and the changes that have been made in its built and man-made environment. Therefore, in the author's view, the effects of globalization in the structure of Islamic cities have generally been unpleasant and, on the whole, seriously damaged these cities economically, socially and culturally, and led them toward an unsustainable development. However, it is also important to note that globalization is an epidemic and unavoidable process, and it is never possible to find solutions to the problems created in the structure of the cities of Islamic countries in isolation and avoidance of this process, but rather in considering the globalization of cities together with the native identity and qualities of societies as a possible and desirable solution and the necessary way to the realization of sustainable urban development. This is the challenge that continues to confront the urban policymakers until reaching executive solutions.

Since the nineteenth century, suburbs were chosen for the living of the rich and middle-class families due to the inadequacies and pollution of the old part of the cities; the development of transportation technology has led urban families to prefer living in the countryside and away from the central part of the city. Access to the countryside is becoming ever easier with the help of vehicles that travel faster day by day. Currently, suburban residence is the predominant way of life in the United States. But with all this, the suburban settlement has many disadvantages, as this way of life has become outdated from the point of view of urban planners and other thinkers, and they have been thinking about other patterns for the settlement of population surpluses in cities, one of the most important of which is that of creating New Cities, proposed by Ebenezer Howard. Although the creation of new cities has a long history in human annals, in the new centuries the suburban area is prior to new cities, in a way that the problems of cities and suburban residents caused by suburbanization encouraged planners to the creation of new cities.

One of the most common and important methods for the regulation, presentation and analysis of scientific findings is the use of statistics science. In the science of geography, the use of quantitative statistics and data is considered necessary. It is also evident in various geography disciplines, including urban geography. The purpose of this study was to visualize facts within the data and analyze them on the basis of statistical information. In order to carry out this task, it was attempted to establish a relationship among population, urban utilities and their waste production in SPSS software using statistical analyses. In this regard, two methods of Inter Regression Analysis and Stepwise Regression Analysis were used. The results of the analyzed data showed that the population and urban utilizations in Tehran justify the garbage produced in different regions in terms of volume, size and shape.
