Quality of urban areas and improvement of it have always been considered as one of the main issues in the process of urbanization. It might be possible to consider this importance as the result of fundamental changes in intellectual patterns during the past two decades in one side and its proposal in all aspects of human life on the other side though this is one of the main influential concepts in urban landscape and vision, and there are various approaches available regarding this matter. These approaches have decreased the nature of landscape concept to simple decorating concept and even considering it equal to any type of interaction between human and environment and it identification. So there are several results for each definition in terms of planning and management. Urban landscape &ndash as the objective of city &ndash is the most impressive urban index for human beings. The issue of lack of attention to city vision and landscape, and efforts in identifying and creating of it, is one of the most important problems of cities. Increase in Population as a threat to city life, migration of rural population to urban areas and large cities, traffic, air pollution, open space, green space and playgrounds and several other issues, are among the items that have been discussed relatively more than issue of urban landscape and its problems and more papers and books have been written on it. Urban landscape is in fact all the elements that can be seen in the city and can be watched by human eyes. These items form urban landscape when they are integrated and combined with several factors in every moment. This article seeks to enhance the environmental quality to organize urban landscape in Sa&rsquodi Street through discovery of historical meanings, cultural codes and local architectural terms in visual landscape of the city, and giving sense to it in physical and visual formats. Therefor with review of Store street in New York &ndash as an foreign sample - and Hamze street in Isfahan &ndash as a domestic sample &ndash the existing situation of Sa&rsquodi street is reviewed and SWOT analysis is then implemented for examining the weaknesses and strength factors and regulating the urban landscape of this street through field-documentary studies.

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.

Improving employment opportunities for people and reducing the economic burden on government requires a broad and concentrated effort on private sectors. Private sector growth is a key engine for creation jobs. The major advantage of private sector is its employment potential at low capital cost. These sectors are the nursery of entrepreurship, often driven by individual creativity and innovation. Entrepreneurs seek opportunities and innovations often provide the instrument for them to succeed. However, certain social, cultural and structural factors are inherent within a society which can affect entrepreurial activity. The purpose of present paper is exploring a set of positive and negative factors which can result in either stimulating or damping the activity of entrepreneurs in Iran. The statistical population includes successful entrepreneurs of Iran’s provinces in 2014 that were selected as sample randomly. The result shows that success achieved by the entrepreneurs is positively correlated with their risk taking abilities. The overall conclusion clears that the family and government support influence

Security as one of the basic human needs has a special place in relaxation, comfort and spiritual needs provision. For this reason, security is always of managers, planners, architects and urban designers' interest. Solutions and strategies of security provision have been fundamentally changed following prevailing change of housing architecture patterns from homes to residential complexes and high-rise buildings. Principles, concepts and patterns of residential complexes form are also more originated from its resources and ideas shaping namely Western culture rather than Iranian-Islamic foundations. Individual and social security is emphasized as one of effective aspects in housing design and residential complexes in Islam. The present study was done aimed to explain a conceptual framework for Iranian-Islamic design of residential complexes. The method is a qualitative type and using documents and Islamic texts and also a few examples of residential complexes and validation by experts. The results of the study show that two main principles are dignity and privacy and subsidiary principles are contentment, clarity, nature, evolution from diversity to unity, classification and spatial hierarchy and proximity of the main structure of conceptual framework of individual and social security in residential complexes.

Biology has been a brilliant teacher and a precious textbook to man-made construction for thousands of years, because it allows one to learn and be inspired by nature’s remarkable and efficient structural systems. Concepts unfortunately have this in common that in general use often specifies incorrectly some phenomena. There was a turning point in each period of time which human has discovered a new sight about the world and nature order in a way, and then has presented this relation by numeral, artful and industrial language. The relation between nature and human considers different periods. At first it was bio-utilization which degrades the value of nature as a source of energy and material. After revolution in science development and attention to the damages which they made to environment, they tried to change their look to this issue and expand the mean of relation between human and nature. Birth of such word like bio architecture emphasize on the new point of view at nature. The role of nature and importance of natural resources in human’s social-economic (and even his psychological) life is undeniable, and also it is essential to note that God is the Creator and man the explorer. This paper aims to call a close multidisciplinary collaboration that promotes engineers to build more sustainable and smart structural systems for bridges in the 21st century. In this article survey the introduction of bionic architecture and related categories.
