Investigation on modern history of urban planning in Iran shows that there are three approaches in the subject under discussion: “Modernism and Westernism”, “Traditionalism and anti-Westernism”, and “Adopt and Adapt”. Proponents of the first approach believe in encouraging methods to use the external concepts. The second, is the idea about ​​cultural and religious values, ​​thereby everything with nontraditional orientation is rejected. In the third approach the thinkers believe that if the parts of tradition are synthesized by modernity, culture and religion can adapt themselves with the development. The purpose of this study is to evaluate the adaptation of traditional urban design patterns of Islamic-Iranian cities in incompatible district of new Iranian cities (spontaneous settlements) and to focus on the application of the third approach in the current situation of Iranian cities. On this basis, the method of comparative analysis has been applied to survey the differences and similarities between historical districts and spontaneous settlements. Studies show that there are rather similarities among physical - spatial parameters (such as structural and environmental criteria) between the two types of districts; because both of these residential districts formed as organic structures that are unstable against unexpected risks and earthquake. However, there are the differences between these two types of districts in organized and formed periods. Despite historical districts that have been consolidated and organized during hundreds of years, spontaneous urban textures formed quickly and without any plan and planning. Meanwhile, the historical districts have usually integrated townscapes and unique materials such as clay, bricks or stone, while this character (integrated townscape and unique materials) never have been seen in the spontaneous settlements. There are similarities in economic and socio- cultural characteristics between residents in the two the types of districts. The residents living in poor economic condition, but under a very strong socio-capital and traditional beliefs; There can be seen several socio-cultural and particularly religious characteristics in people of historical residential districts that are similar with the spontaneous residential places, such as “strong relationship among families, friends”, “hospitality”, “mutual relationship among family members”, strong religious beliefs and the needs for privacy and security. However, these communities are different in some principles such as quality of life and spatial and physical qualities especially in favorable and beautiful urban landscapes. So it can be extracted and adopted excellent principles from traditional and historical districts and adapt them to the inappropriate modern urban districts. With regard to the existence of these similarities, we explain applicable principles of the spatial characteristics and designing quality in the historical district of Yazd to apply in Baghshater District in Tehran as a spontaneous settlement. Findings show that we can use several solutions to reconstruct this zone included: 1) land readjustment as the suitable solution in Baghshater District with regard to the familial residential pattern in historical zone of Yazd such as Fahadan District. 2) Focusing on the traditional concept of mutual relationship in residential houses. 3) Emphasizing on the hierarchy of The entrances and exits of the residential units.

With emergence of urbanism, complication of urban community system, and occurrence of urban problems, a new paradigm of urban management was introduced that adopted new methods to involve citizens in policy making, planning, and supervision and direction of urban life. Therefore, the main element in managerial methods is involving citizens in urban life. Among the ways to make urban residents into real citizens is training an informing them. What everyday life suggests is everydayness. Everyday life is the very everyday life that is spent on repeated and everydayness activities such as work, rest, commutation, shopping, which all are boring and follow a predictable procedure. Urban spaces inevitably are background of large part of citizen’s everyday life, and therefore, undoubtedly interact with it, which means they both influence and are influenced by the individuals’ everyday life. This paper aims to collect and analyze literature on such interaction. Relation between urban space and everyday life has different aspects. However, they are placed between two contrasting ends, and tend towards one of them: everydayness and daily life; the latter of which suggests creativity, vividness and efflorescence of everyday life. Such life leads to lived experienced and creative moments for an individual, contributing to his/her balanced development. Such life, in the first place, realizes in a space which has individuals actively involved in its production and protection; and formation of such space has not been formed to impose dominant system’s values and rules on individuals. It is only in such space that physical and social dimensions of space are aligned, and spontaneity and efflorescence of urban life realize. It is in such space that diversity and individual differences are maintained at the same as keeping social sustainability. In other words, it is in such space that one can attain the right of being: one can live irrespective of his/her economic status, sex, education level, etc. In such space, individuals’ human rights in terms of access to urban requirements are observed and are subject to justice; people have the right to choose between proactive involvement in collection actions, and interactions, and retirement and relaxing from burden of urban life; collective memoirs of city are formed, and in addition to “form”, the space will acquire a “structure”, which remains in the people’s mind as a common thing. Memoirs that are embodied again as they are recollected, and as Agness Heller’s said, are reviewed in quiet and peace. Such review sets human mind free of sinews of everydayness, and directs towards criticism of the surrounding world. This paper was conducted using description-analytic method. Data collection was carried out using library (documentary) and field methods. This paper tries to study challenges and consequences of training of citizenship and relationship between urban space and everyday life.

Hail phenomenon is one of the hazardous weather phenomena that can make the highest amount of damage to farms, gardens, cars, rooftops, etc. in a very short time (a few minutes), depending on the diameter of the particles. One of the best ways to study this devastating climatic phenomenon is the use of atmospheric instability indices. The indices which are calculated with the help of radiosonde data give a fairly comprehensive vision regarding the occurrence of such phenomenon. In this study, the incidence of moderate to severe hail is investigated in the period of 1990-2010. First, the atmospheric codes related to hail phenomena were applied to extract the data, then radiosonde data in intended time were received and applying the RAOB software, the physical status of atmosphere was studied. In the studied period, two hail examples were reported on November 27, 2008 and December 5, 2008. In the first instance of hail that occurred on November 27, 2008, the status of some indicators was calculated and it was found that LCL was at an altitude of 284 meters, CCL at an altitude of 1582 meters, LFC at an altitude of 6230 meters, the ice surface at an altitude of 3278 meters, the LI index was -0.2, the K index was 25.7 ° C, and PWC was 28 mm. In the above mentioned conditions, there was a hail with a diameter of 25.4 mm. In the second instance of hail that occurred on December 5, 2008, the status of some indicators was calculated and the results showed that LCL was at an altitude of 280 meters, CCL at an altitude of 1762 meters, LFC at an altitude of 2271 meters, the ice surface at an altitude of 2771 meters, the LI index was -1.4, the K index was 27.1 ° C, and PWC was 23.6 mm. In the above mentioned conditions, there was a hail with a diameter of 3.6 mm. Given that in many ways, the status of most atmospheric indicators in the two above examples of hail were close to each other, it turns out that in similar circumstances, the greater the distance the ice level gets to the summit of cloud, the greater is the probability of hails larger in diameter. The value of this distance for November 27, 2008 was at approximately 6384 meters and for December 5, 2008, it was at about 5012 meters.

In today's communities achieving to effectiveness of urban advertising is one of troubles of advertisement industry. This research is trying to answer this question that using three-dimensional design in urban advertising has what place in urban field? This query has been conducted in the method of iconological analysis on chosen urban advertising works of last 15 years in the world with the goal of achieve to volume effect on effectiveness of public advertisement. Results show that reason of effectiveness of chosen urban advertising (billboard) of last 15 years in the world (2000-2015) is -due to public audience of commercial advertisement and services- using volume display in the amount of 86.7% which among this number 83.3% of them have interacted with around environment space.
