Green architecture, or green design, is an approach to building that minimizes harmful effects on human health and the environment. The “green” architect or designer attempts to safeguard air, water, and earth by choosing eco-friendly building materials and construction practices. So, green architecture is Building and structure design philosophy that aims at minimal use of non-renewable and/or polluting materials and resources in construction and use of a facility. Today, architecture finds itself at a crossroads. Building materials and new construction, along with the operation and maintenance of buildings, account for a significant sum of the world's greenhouse gas emissions. Faced with this fact, how are architects to responsibly pursue the act (and art) of building without further deteriorating the planet's environmental make-up or depleting its resources? What forms of high and low technology can be developed to curtail the injurious side of building? Can good or even great architecture be sustainable? In this paper discuss the problem such as: The Future Is Green: Architecture + Sustainability and have been surveyed Green Architecture and impacts of it on urban planing and urban design.

Passive Defense is a set of civilian efforts performed to enhance deterrence, reduce vulnerability, sustain essential activities, promote national stability, and facilitate crisis management against military threats of an enemy. Since in battles, sensitive and critical areas of cities are of paramount importance,it is clear that in military agressions, a large part of threats are focused on cities and their urban facilities and equipment, especially fuel centers. As a result, consideration of passive defense while planning cities has a significant role in reducing the vulnerability of cities and their urban elements as well as facilitating the urban crisis management. It also provides the citizens resistance threshold under possible enemy invasion and natural malicious agents. Hence, this article reviews and analyzes the current situation of gas distribution centers and evaluates their positioning across the city of Mashhad with regard to passive defense approach. However, as far as there is no clear- cut criteria for organizing fuel centers with passive defense approach, the Delphi method is used to select the desired criteria in which on the basis of the final comments of the experts, four critera- performance, access, hazards and security election and spatial organization of the fuel tanks and petrol stations- are analyzed using AHP model and GIS spatial analyzes. Accordingly, it can be said that the assessment of the current status of the urban fuel stations in Mashhad indicates that no area of the city enjoys all measures of passive defense (performance, availability, security, and risks). Likewise, the results indicate that the distribution of these centers in the city are mostly consistent with the factor of access. taking into account all the criteria, it is the ​​North West of Mashhad which has the highest utility than other areas. It is followed by the east of Mashhad and ​​the Northeast and the middle east of the city, respectively. Accordingly, it could be stated that ignoring an efficient design for determining the optimum location of the site construction with a passive defense approach results in an inappropriate and naive spatial distribution of the stations leading to an increased security and environmental risks of the city.

Background: This study aimed to identify factors contributing to the creation of intellectual capital in the organization of education. The research method is a descriptive and exploratory factor analysis method. A sample: directors and deputies of the second period Secondary Education Department of Tehran Province. Based on stratified random sampling method and based on a sample of 500 was calculated size formula. The research made questionnaire constitutes a measurement tool through which factors in the creation of intellectual capital was identified by the sample. Validity to help them with the help of factor analysis and reliability was confirmed by Cronbach's alpha equal to 78/0. And finally analyzed by factor analysis of main components were analyzed. The findings suggest that the amount of KMO is close to 1 is equal to 881/0. Bartlett test of sphericity is also characterized by a significant level of zero, which is smaller than the 05/0 show statistically significant. And the final outcome of the 9 extracted with PC using varimax rotated in total by performing factor analysis identified nine factors: Self-conscious, value-based and central vision, holistic and systemic approach, independence, spontaneity, sense of mission, altruism, accountability, change frame of mind Factors identified in order to create intellectual capital could have a significant relationship with the studied variables. So successful, in order to strengthen each of these factors will lead to the creation of intellectual capital in educational organizations.
