In order to promote and improve the quality of educational spaces and achieving a comprehensive statistics, evaluation and analysis of schools neglected in most Iran’s schools, while educational spaces play an important role in the social and cultural structure and population growing and schools as one of the most basic educational centers, study on this field is important. Therefore, schools evaluation (in the Shahriar city as a case sample) plays an important role in raising the scientific level of a country and development of urban physical planning in the field of education. It supposed that the schools of Shahriar city in terms of population, area and other qualitative and quantitative aspects are far from per capita and standards of the country’s modernization organization, and according to this hypothesis, to what extent are schools far from relevant standards in terms of population growth, and what are solutions to fix and reform schools? This study is a descriptive - analytical and field study, to collect data, city education department; organization of schools renovation, journals and valid books and papers were used. Then, the date of Shahriar city’s schools to determine its distance from per capita standard was assessed and compared. The study result shows lack of schools area in term of population and per capita standard was about 310 thousand square meters in Shahriar city that will reach to 700 thousand square meters in the future 25 years.

Studies addressing such concepts as place, sense of place, place attachment, place identity, place dependence, rootedness, genius loci, topophilia, and place-making can be found in count-less disciplinary and applied fields devoted to the design, planning, stewardship, and restoration of places that vary in kind and scale from homes, neighborhoods, and cities to parks, and ecosystems. This article identifies opportunities and challenges to using sense of place as motivation for long-term stewardship at multiple spatial scales in a rapidly changing world. Sense of place reflects processes by which individuals or groups identify, attach to, depend on, and modify places, as well as the meanings, values, and feelings that individuals or groups associate with a place. The results of research show that An overview of the defined sense of place shows that sense of place is a result of the relationship of Man, his mental imaginations, and environmental characteristics. The concept, on the one hand, is rooted in the subjective experiences such as memories, traditions, history, culture, and society. It can be affected by the objective and external effects in the environment such as design, landscape, smell, and sound, on the other hand. Accordingly, sense of place is a complicated concept of the human feelings and attachment towards the environment that is produced due to the adaptation and use of place by the human. It means that sense of place has not been a predetermined event but results from the human interaction with the environment.

The electronic industry suffers a rapid changing and highly rival environment. Thus, firms have an essential need to strive for acquiring the competitive advantage. Strategy Organizational Agility (SOA) is a tool which enables to assist firms to attain the competitive advantage. Therefore, this study benchmarks the core competencies from a case study within the supply chain network and establishes a set of attributes for augmenting SOA. A novel multi-criteria decision-making structure is proposed to deal with the complex interrelationships among the aspects and attributes. Radial basis function (RBF) neural network can use linear learning algorithm to complete the work formerly handled by nonlinear learning algorithm, and maintain the high precision of the nonlinear algorithm. However, the results of RBF would be slightly unsatisfactory when dealing with small sample which has higher feature dimension and fewer numbers. Higher feature dimension will influence the design of neural network, and fewer numbers of samples will cause network training incomplete or over-fitted, both of which restrict the recognition precision of the neural network. The competence and accountability indicators can the continuously increasing level of agility to be effective. According to the analysis chart production and product design performance indicators alone cannot level a considerable amount of agility to change. But reducing the level of the index level of agility is reduced. Flexibility indices speed and agility level changes can also affect the organization. But with increased levels of these two indicators increased agility rate change indicators will be more flexibility. The results showed that customer knowledge management impact on organizational agility and organizational effectiveness and customer knowledge management through organizational agility has significant positive impact on organizational effectiveness. Finally, some practical suggestions, future research suggestions and research limitations are presented.

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 last decades, the skillful planning of land resources has become a major issue for rural development. The development of cultivated areas becomes gradually impossible due to ever increasing population growth and urban development. Fuzzy logic is preferred to Boolean logic for land evaluation, because fuzzy techniques lead to estimate for land use suitability on a continuous scale and can therefore, be more informative than the Boolean technique. The objective of this study is to apply fuzzy set methodology in the context of a decision making process known as the Analytic Hierarchy Process (AHP) to land evaluation for irrigated wheat. The results revealed that the results obtained with fuzzy AHP method are in better agreement (R2=0.911) with the observed yield as compared to those obtained with parametric method (R2=0.804). Although, the fuzzy AHP provided more efficient and accurate results than parametric method, the choice of membership functions, width of the transition zones and weight values are determinant to achieve its realistic results in land suitability assessment.
