Urban has been defined as an autonomous and complex system. Despite the overwhelming differences between urban growths around the world, their growth still follows some universal mechanisms. Darwin’s theory of evolution might have enlightened an innovative view to perform the research of urban development, as a consequence many researchers have been trying to link their research to the biological metaphor of urban evolution. In the context of an analogy to biology, urban can be seen as ‘organic’ and many concepts from biology can be borrowed to explain the ‘uncertainty’ and ‘relativity’ of urban growth processes. Urban DNA is one of the innovative concepts, which has been used to describe the unique characteristics of urban and the common fundamental elements of each urban area. As Hall (2008) stated “every city has its own DNA, something that makes it unique, and that's part of what makes this city unique”. The main ideas of applying the concept of urban DNA involve identifying the key factors/ metrics which reflect urban characteristics, therefore allowing the understanding the cities’ characteristics with urban DNA. This would allow, among other things, to identify or propose optimal urban form and allowing ‘smooth’ transition of growth patterns and the characteristics of urban from a suboptimal urban form. As Silva (2004) explained, the possibility of defining this ‘key’ (DNA) for each region seems to be of great significance in the planning studies. It allows for the understanding of how the different elements that constraint the functioning of urban system progress and constrain different regions, and what function they should have in shaping future scenarios. This research explores the theory aspects of urban DNA, and makes an attempt to link this concept with an integrated urban growth model (DG-ABC). The simulation results of a pilot study are analyzed in the context of the biology analogy in order to test the possibility of deriving urban DNA from DG-ABC model, by doing so we hope to understand how the key factors and parameters influence the formation of urban patterns, and therefore allowing making optimal solutions to urban growth problems.

The wide-spread use of online social networking sites has sparked many psychological issues and research around the globe. A unique phenomenon has come into existence in which people rely on Facebook to satisfy their attachment need. It is one of the very innately psychological needs that presents throughout a life span. The present study investigated the interaction between attachment style and social networking site use. The result showed that attachment style contributed significantly to the level of social media use. It also pointed out that the attachment style distinguished significantly between active and non-active users. Future research and implications of the study were discussed.

This paper, first, briefly explained the usage of method in urban design process .then, configurative specifications of Mashhad's -one of the oldest and religious city of Iran- spaces are analyzed by space syntax methodology during three historical stages of its development (first stage, mashhad within the defensive wall limit; second stage, development of the city beyond defensive wall and construction of market, and the third stage, after street forming in 1940s), and the following results are to be used in the process of urban design. The urban spaces have shaped based on the structural logic. Manipulating or Intervening in space syntax method transforms the spatial structure of city. The analysis of urban space configuration, by using the “space syntax method”, enables the skillful society of urban designers to make the model which can predict the behavior in urban spaces.
