Integration and coherence within a city’s physical structure have become an issue for towns and cities as they rapidly expand, incorporate new elements, and undergo incessant changes. At present, we are facing an extensive accumulation of signs and traits in modern urban patterns; many unaccustomed to and incongruous are affecting the socio-cultural and physical characters of cities. Here, we will be discussing whether it would be feasible to create a system of domestic signs which would reflect domestic social values and mental images held and entertained by citizens, and thus to re-create the sign system of cities. We will also discuss factors involved in interpretation of signs and symbols within a city structure. To prevent emergence or exacerbation of contradiction and disunity within syntagmatic urban structures which have been formed through centuries, we must acquire the knowledge and skill necessary to contain the newly adopted elements and assimilate them into a meaningful and coherent whole. In line with this goal, we have conducted a study of changes of physical structures of the city of Yazd through time (a diachronic analysis) with the aim of identifying sustainable parts of the city’s sign system and with an emphasis on the extent in which it has been formed. The questions which were the motivations behind this work and which we will be trying to answer are: Can the sign system within a city be used as a means for creating an alternative structure within the city’s physicality? Is the sign system (as a tool) characterized by specific patterns on whose identification the coherence of the physical structure of a city depends? How can we achieve an appropriate paradigm within an urban sign system? Here we will try to identify processes of integration of modern urban structures into a city structure, and we will do it through combining views held by semiologists with the ideas of urban incongruity and contradiction, which arise as a result of introduction of modern structures into old cities. To transform the medley into a coherent entity, we need to be aware that cities possess markedness. To this end, we have employed the structuralist analytical method with an emphasis on identification of syntagmatic structures (identifying the structural elements and their relative positions within a city) and of paradigmatic patterns (the ways in which elements substitute for or replace one another). Our main aim here is to extend the scope of studies of urban semiology and introduce analytical tools including the use of structuralism theory in the analysis of urban patterns. We have conducted an in-depth analysis of subjective and objective causes of appearance of signs within cities. We have then conducted case discussions as well as discussions about backgrounds and have tried to establish past and current trends of these signs and symbols in Yazd. Extended data were analyzed based on theoretical notions, paradigms and principles governing systems of signs and symbols have been sought.

Effects of neglecting climatic patterns in buildings are more intense in severe climates such as tropical. It is resulting an excessive consumption of fossil fuels and consequently environmental pollutions in and after modern era. The objective of this research is to find climate-oriented intentions and solutions in tropical areas and compare them with Dezful and Bandar-e-Lenge vernacular houses to exامینe how differences in mesoclimates may affect the climatic pattern of buildings. The present study will initially classify the experts’ viewpoints on the architectural patterns in tropical climates and prevailing targets, solutions, and will present features of the architecture in such regions. The solutions are tested on vernacular buildings of Bandar-e-Lenge and Dezful. The findings demonstrate that in the above areas, climatic solutions have been used to moderate high temperature and humidity. The local houses in Bandar-e-Lenge are in accordance with both climatic objectives but the houses in Dezful pertain solutions for only high temperature. Results also confirm that the difference can be observed because of the different sub climatic groups they are placed in.

City growth and environmental difficulties last decades leads the art of urban design and development think more precisely and new approaches for conserving environment and developing urban areas have been evolved.The present study deals with concepts related to ecology in the city and in particular the theory of Ecological Urbanism and its criteria is expressed. Also theory and characteristics of cultural landscape is described. Persian traditional architecture and urban design especially in historic urban fabric has unique criteria, Shushtar ancient urban fabric is investigated in this research and its extraordinary characteristics are compared with theories mentioned above.This paper is based on quantitative and qualitative research methods reviewed recent and reliable articles and documents. Also case study is assessed by reviewing, historical books and different official documents in addition a complete assessment of case study is performed by site survey, socioeconomic survey, physical survey, and demographic analysis. Plenty of data gathered by questionnaires, interviewing officials, authorities and residents. Result came out from comparison theories and case study indicates that Shushtar has both ecological urbanism and cultural landscape values and it could be argue that cultural landscape are special features of the culture, art and relation between human and nature in each society, they were existed long before the eco urbanism criteria formed, yet, it seemed there are some similar criteria to define them that illustrate the inseparable fact and relation between them.

Large cities and metropolitan areas in developing countries are growing rapidly. These areas grew by attracting all facilities, services and capital of the country. Tehran has been the major city and center for decision and policy making in various administrative, political, economic and socialaspects. This political focus has brought economic, social, educational focus that attracted a vast majority of students of Iran. Based on measures by TOPSIS technic, Tehran province has ranked 19th in terms of development Indicators; therefore, its status is not favorable. There are total of 91 universities or educational institute in Tehran province 75 of which are located in the city of Tehran. There are 527 thousand students currently studying in these institutions which itself indicates the focus on capital city, especially in the field of education. National programs should take decentralization policies from growth poles. Decentralization of higher education as an integrated development policy for Tehran province and the country can bring many fruitful results. Based on recent policy on decentralization, cities of FiroozKooh and Damavand are proposed for attracting students of Azad universities and Varامین is proposed for attracting Payam-e- Noor students of the province and Hashtgerd is proposed for accepting part of activities of governmental universities for undergraduate studies as appropriate locations for identical spatial distribution.
