Recognition of Renovation Methods Capacities in the Semi – old Urban Textures in Tehran based on Physical and Social CharacteristicThe Case: 19th District of No. 17th Region, Tehran Municipality

Extended Abstract

Introduction
The interior textures of cities are the spaces formed in course of rapid town formation from 1966 to 1978 . Nowadays, these textures in large cities, including Tehran, are deteriorating. The core population and social centers of these textures has enabled them to be used as internal core points for any reconstruction and rehabilitation plans .
Wide range of civil eroded texture on one side, and vulnerability of such areas due to the disasters (particularly earthquake) on the other side, turned the rehabilitation or renovation of the mentioned areas as one of the main problems in the urbanization field. This is while two space-based and man-based approaches may discuss different directions when renewing such textures. Current study is going to find the way which such textures contact together in the area of one of the eroded textures located in the middle of Tehran with a combined approach based on the community properties on one side and space properties on the other side, stressing on their internal system with a logical approach. Zone 19 of district 17 of Tehran metropolis has been discussed as the basis of this study due to its situation as located in the middle of old and new textures and its situation in the realm of eroded textures. This space has obtained its main name of temporary urbanization and borrowed its social system of immigrants with different sub-cultures but combined ones maintained their social integrity by tribal-lingual compositions until now. This resulted in more value for residing and living in this texture besides its erosion. On the other hand, space possesses homogeneity properties in the field of housing and residence and this has also minimized diversity and relatively eliminated its body integrity. Results of current study, made by descriptive - analytical method using field survey (observation and questionnaires) indicate that the weakness of conjunction between space and community in the emergence and exploitation stages resulted in weak and eroded forms such as social structures. Reviewing this research practically can provide us with understanding the strengths and weaknesses in both fields (society and space) as well as a background with applying results in the renovation stage.

Methodology
The used method in this study is descriptive – analytical, insisting on the indices based upon theoretical subjects. It is a case study in the form of literature review and field study and analyzes the social (by sampling from the 400 households) and space (survey of all elements) specifications.

Findings
The finding, based on theoretical foundations, shows that there are some aspects among the residents of these textures, including commitment and participation which is in turn the result of marriage between the relatives . In addition, there is a relative solidarity in the anatomic texture of the zones which is the result of some equal opportunities, facilities and inter-related elements of the texture. Such specifications have made these texts dynamic.

Conclusion
The deterioration of these textures is the result of divergence between the community and the space. Whenever there is an appropriate solidarity between the space and the community, the needed possibilities and facilities for promotion of the deteriorated textures are prepared through reconstruction and rehabilitation. An aspect, which decreases the resulting costs and increases the benefits for the relevant groups and the potential beneficiary
