With increasing frequency, the developing countries and the people living there are being affected by disasters. More and more often, development efforts are being destroyed. The reason for this trend is their growing vulnerability, which in turn is the result of economic and social development processes, such as the expansion of settlements and agricultural land in risk areas. The economic and social consequences of these disasters for the people in our partner countries last for years. To break and, if possible, reverse this trend, international organizations, governments and NGOs in the developing countries are increasingly upgrading the priority of disaster risk management for policy, and taking concrete preventive measures to reduce the risk to the population. This paper examined the concept of disaster and its management in the light of sustainable development with particular reference to Iran. It enumerated the different human and natural phenomena that could be characterized as disasters. It was discovered that, while hazard and/ or disasters possess anthropogenic origins, their consequences are felt on both human and the physical environments. In all cases, the human tolls have been significant. The paper highlighted the important elements of a typical Disaster Management Information System in Iran. After presenting a typology of disasters in Iran, the paper, advocated for a workable disaster management information system.

The subject of geometry and proportions has been regarded as an issue which has a close relationship with architecture. Since the entire universe, living beings and the human geometry can be seen clearly, that’s why our unconscious essence has accustomed to these proportions whereby reflection of this mentality can be seen in the architect’s hands and thought in the architecture. It can witness a close linkage between nature and architecture at different levels in Iranian architecture which the linkage at architecture geometry has been regarded as one of these levels. Iranian geometry using plant and geometric forms in Islamic buildings seeks to prove a special continuity in the life to plant and human world. This continuity in the world of geometry has been known with fractal geometry. The present research seeks to examine dimensions of fractal geometry in Iranian architecture and motifs. In following, an attempt is made to examine what the fractal means in Iranian architecture and clarify the motifs and decorations of Iranian architecture after defining the issue of fractal, fractal geometry and fractal in architecture.

The aim of the present study was to identify dimensions and dimensions and components of improving the educational quality of graduate students (master). The statistical population included all faculty and students of Islamic Azad University, Science and Research in the city of Bushehr. The sample size in accordance with the Morgan table was estimated about 201 faculties and 351 students, and that number was randomly selected from the population; Data collection instrument was a questionnaire with 93 questions, five-point Likert's scale, and the alpha coefficient of 0/95. The collected data was analyzed using exploratory factor analysis. The obtained results identified 10 dimensions and components of the students economic conditions, student facilities, library services, faculty, students, curriculum, teaching and learning methods, good communication, academic facilities and administrative services as dimensions and components of improving the educational quality of graduate students ( Master) Azad University of Bushehr, and the overall impact of these factors was 56%.

The problem which has been the focus of city constructors and architectures since the beginning of citizenship life is the issue of the nature of environmental quality. This study, with a review of explaining paradigms of environmental quality and by reliance on basic works, has assumed the question of nature of environmental quality an interdisciplinary concept (civic construction, sociology, psychology) and is in seek of explaining perceptive quality factors from citizens' perspective. Since the nature of this study is multidimensional and understanding of its different aspects and answering of its relevant questions bounds researcher both to test present theories and to understand mental world of his or her subjects, therefore, synthetic approach has been applied for methodology of it. It should be mentioned that Delphi method has been applied so as to obtain different indices and factors of the study. To determine the unit of sampling, multiple-stage clustering sampling method has been used in a way that between 22 regions of Tehran municipality, based on their development, first 6 regions were selected and in the next stage all the local states of those 6 regions were listed and then six local states were randomly selected. Size of the sample of this study is 200 persons. The results show that most of the perceptive factors derived from qualitative section of the research conform to factors derived from quantitative section and questionnaire. In other words factors derived from qualitative section are the same as those derived from quantitative factors. The significant point to notice in this section is that some of the derived factors from this section couldn’t be categorized by previous theories but rather they belong to the research community of this study (i.e. local states of Tehran). Thus we can state that the total perceptive criteria of environmental quality of these local states are as follows: legibility, place atmosphere, permeability, peace, tranquility, liveliness, sensational rapture, time sense, civil justice, security, human standard, sociability.

The backwardness of the countryside is most important issues of developing countries. The result of this study, based on descriptive - analysis studies, shows that revive traditional arts and crafts with much charm with planning and organizing on development stimulus projects, can direct influence on the villager’s empowerment. Of course, the existence of such attractions, itself, without providing proper bed in the field of empowerment, has not the capability to introduce and identifying. Hence, there is appropriate site in the village of Laft in empowering the intellectual and cultural treasures. The creation and the spread of such projects, in addition to revive traditional arts and crafts provide empowerment and development of Laft villages.

Threats are one of the most fundamental problems of our modern societies that daily will affect citizens in urban spaces. This becomes more problematic when the people in their everyday living spaces encounter with behaviors that cause lack of security and should have been feel comfort and their families used these spaces freely. This causes many problems for citizens. In today cities because of the increasing growth in construction of residential complexes and high population density in a little area comfort ​​ with more problems and security is more important. So providing security in outdoor and semi-outdoor spaces of residential complexes is not exact scope and is very important. In this study using the analytical-descriptive method and library studies, the factors influencing the security of residential complexes in the form of a conceptual model investigated.
