Abstract
This study aimed measurement the farmer’s vulnerability and readiness for facing with drought conditions in rural regions of Kashmar County. Applied research and survey method was used to collect data. The study population consisted of 8242 farmers in Kashmar County. Using Cochran formula and multi-stage sampling, 150 of them were selected as sample research. Data collection tool was a questionnaire which its validity was approved by agricultural extension and education specialists and Jihad-e-Keshawarzi experts in Kashmar County. Reliability was evaluated by conducting a pilot study and Cranach’s alpha coefficient for different parts of questionnaire including damages and losses caused by drought and farmer’s knowledge and awareness rate from methods and strategies to deal with the phenomenon of drought, respectively, were 0.78 and 0.84. The results showed that the most important of economic damages, respectively, were increasing the Forages prices in the region, increased production costs and reduce the amount of investment in production. The most important of social-psychological damages, respectively, were seasonal and permanent unemployment among farmers, family farmers migrate to other areas, and more dependent on the government and the most of environmental damages, respectively, were low level of groundwater, wells and aqueducts, dry surface and invasion of pests and diseases. There was a significant relationship between farming experience, age, number of family members, amount of agricultural activity income and level of facilities and equipment available to deal with drought respondents and their assessment of damages caused by the drought. Comparison of vulnerability levels showed that most of the damages were due to environmental damages and then is located economic and social-psychological damages.

Abstract
Human impact on the environment are increasingly of urban life arises that this is due to human population growth is partly a result of technological progress. Cities as the center of attraction of population with multiple and various environmental problems such as air pollution, noise, waste, and water pollution this leads to increasing pressure on the environment and therefore the incidence of environmental pollution. The study aimed to measure and evaluating the quality of the urban residential environment with cross-sectional approach in urban settlements Ardabil province. To achieve the goal of is evaluated 5 environmental factors (environment, energy, environment, social, cultural, recreational and employment) in the form 30 Index. Rate the importance of each of the variables were determined using the Shannon entropy. Models used to analyze the data is Visual PROMETHEE PROMETHEE and GAIA software. The results show that urban settlements Kosar city with a score of 2,674 / 0 has favorable conditions, Bilesuar, Namin, Sareyn, as well as the privileges 1281/0, 1147/0, 0994/0, 0924/0 has favorable conditions, Meshkin with a score of 0369/0 in relatively good condition, Warmth, anklets and Ardebil with 0704 votes / 0-, 1359 / 0- and 2098 / 0- of adverse conditions And Pars Abad city with 3228 negative rating / -0 in last place and the situation is quite unsatisfactory. Based on the analysis of the 30 indicators used PARSABAD Gaia city status this research indicates that only in the ratio of active branches of sewage into the urban population in the state is ideal. Overall results show that environmental situation in cities far worse that the urban population is more urban counties that have less.

Abstract
Importance of location factors substantially change the climatic phenomena and developments can be enjoyed. Influence of these factors can be strengthened, diluting and determine how the distribution of climatic processes be flashed as a result recognizing the role and relationships of these factors can lead to the understanding of the spatial patterns of climatic variables and the improvement of environmental planning. Accordingly, in the present study using monthly rainfall data of the synoptic station 121, climatology and rain Northwest of Iran in the period of assessment 1987 until 2014, and the use of the data, elevation, latitude, tilt and direction of tilt was trying features and relationships in spatial distribution and location factors of rainfall changes about the analysis. Therefore, the purpose of the center of the circle, half the average of the standard geographic change and even regression (GWR) was used. The results of the investigation showed that during the month of October due to the low amount of variance in the Western region, winds, rainfall, low spatial and spatial factors play an important role in the changes of precipitation. In November, while strengthening the system of precipitation in the region, the role of spatial factors in changes to rainfall reaches its peak in December, but due to the power systems of the proper moisture and nourishing rainfall, of the role of regional rainfall eased on location factors and changes in precipitation are more associated with atmospheric agents.

Abstract
Flooding is a natural hazard. This phenomenon carries significant importance for Iran which is one of the world's six countries in terms of accident. Synoptic conditions of atmospheric circulation patterns are very important in identifying the risk factors that lead to flooding in heavy rainfall. This study used Morghak hydrometric station's daily and hourly discharge statistics as well as daily precipitation data from the rain gauge stations and surrounding area during the period of 1360- 1388. Flooding date in the basin was extracted in order to study the flood-causing system in BAZOFT basin. Then, days of widespread rainfall in the questioned territory which synchronized with the occurred flood date were determined. Afterwards, four main patterns were specified through a cluster analysis on Euclidean distance of flood data in 487 sea level pressure. Thus, these four patterns were analyzed in terms of sea level pressure, geopotential height at 500 and 700 hPa, wind components, moisture flux convergence, and Omega. The results of synoptic maps analysis showed that when floodwater occurs, low pressure tab of the Mediterranean and Sudan spread toward the south-west of Iran and BAZOFT basin. The Mediterranean, Black and Red seas have played a role in strengthening the aforementioned tabs. Positioning of western wind through axes with cut off low pressure in this basin is the main factor of severe inconsistency and heavy rainfall. The results of the analysis of the convergence of moisture flux showed that torrential rainfall was mainly a result of water flow from the Sea of Oman, the Persian Gulf, the Mediterranean and the northern half of the Red Sea to the BAZOFT basin and moisture accumulation in the basin.

Abstract
Introduction: The climate of the earth has begun to warming since 1980’s which has created very serious problems for the human living and natural environment. As a result the study of the global warming and its solutions has become the focal point of the climate change research all over the world. The climatologists are trying to understand, predict and finally give solutions to it. Many different models have been developed to predict and project the future climate conditions among which the Regional Climate Model is to some degree has lower values of uncertainty. The impacts of climate change is relatively higher in the
naturally dry climate of the Middle East including Iran. Here the main parameters of the climate that is temperature is increasing and precipitation decreasing. As a result the projection and understanding of these two elements are very important for the region and Iran. For this reason this studyhas focused on the efficiency of the Regional Climate Model in projecting the future climate of the region and Iran.
Data and Methods: In order to test the efficiency of RegCM 4.3the monthly temperature and precipitation
Data were extracted for the window 24N-40N and 43E-64E from the ECMWF database with spatial resolution of 2.5 degrees. These data were compared and corrected with the station data of Bandar Anzali, Bandar Boushehr, Mashad, Tehran, Yazd, Zahedan, Khorramabad and Zanjan . The simulated model data for RegCM 4.3were extracted for the same period and area with the same spatial resolution. Both data were transported into the Matlab environment and compared.
Results and Discussion: Results of simulated RegCM 4.3data were compared withobserved data of eight stations. The temperature data were slightly (about 2 degrees C) more than observed data. But the precipitation projections were somewhat complicated. The values of rainy stations such as Anzali were overestimated ( about 257 mm) while that of most dry stations such as Zahedan were underestimated (about 58 mm). But the RegCM 4.3 simulations were the same as the observed data inthe normal stations such as Zanjan. The results showed that the RegCM 4.3is suitable for projecting temperature data more than the precipitation. This is in agreement with the findings of many other studies.

Introduction
Regarding the importance of entrepreneurship especially among rural women and its effects on the economic and social development of today’s societies, explaining the status of entrepreneurial motivation indices (progress) among rural women, as well as identifying factors that can be effective in strengthening these indices, is of great importance. Moreover, investigating this subject in villages of Kurdistan province as one of the less developed regions of Iran considering the economic and employment problems can be regarded as the first stages of study about entrepreneurship; because understanding the status of progress motivation and its affecting factors among rural women entrepreneurs in the area under study can help rural development in different dimensions. Therefore, considering the above cases and in line with entrepreneurship development among rural women of Kurdistan Province, the aim of this study is the analysis of affecting factors on entrepreneurial motivation (progress) among rural women of Kurdistan province; in this regard the present study faces with the following fundamental questions:
1- What factors affect entrepreneurial motivation (progress) among women living in rural areas of Kurdistan province?
2- How effective are each of the determining factors of the entrepreneurial motivation index (progress) among women living in rural areas of Kurdistan province?
Key Words: Need Achievement, Women Entrepreneurs; Rural women; Rural entrepreneurship; Kurdistan province
Materials
In this study, for collecting literature of the subject and review of literature, library studies, articles and the studies related to the subject of the study were used and for the other part of the required information, questionnaire and field study has been used. Validity of the research instrument were evaluated and confirmed as convergent by consulting experts and university professors (face validity). For measuring the reliability, combined reliability coefficients (more than 7/0) and Cronbach's alpha (more than 7/0) were used, and if these coefficients are appropriate, then the research tool is reliable. The statistical population of this study were all women entrepreneurs living in rural areas of Kurdistan province (Sanandaj, Marivan, Saqez and Baneh). The studied sample were determined considering the existing limitations and using Bartlett et al. (2001) table; 100 women (women entrepreneurs) by using a random stratified sampling method and appropriate assignment among the considered women entrepreneurs were selected and the necessary information was collected.
Method
The present research is considered as an applied research in terms of its purpose. On the other hand, according to the data collection method, this research is classified as descriptive (non-experimental) research among the various methods of descriptive research, the method of this research is a type of correlation research that is specifically based on the structural equation model. In this study, both descriptive statistics (frequency, frequency percentage, mean and standard deviation) and inferential statistics (correlation analysis, regression, and structural equation model) were used to analyze the data. In this regard, in order to increase the accuracy of data analysis, related softwares such as SPSS and Smart PLS have been used.
Discussion about results and conclusion
In the structural model of this study, economic conditions, improvement of the efficient social communication, extension training programs, policies and desirable supportive rules, infrastructure and geographical capabilities of the region and technological accessibility were confirmed as the determining factors of the emergence of progress motivation among the rural women entrepreneurs. It should be noted that the role of technological accessibility is superior to other determinants and had a stronger effect (426/0). This indicates that accessibility to new technologies factor such as Internet, in addition to familiarizing the entrepreneur individual to the advances made in the context of his/her desired idea, can easily communicate with experts, consultants and specialists more easily and solve their problems easier and faster and transfer the considered information fast. The results are consistent with the results of the studies of Golrd (2005), Jamshidi et al. (2013), Hosseini Nia et al. (2014) and Roomi and Parut (2008).
Making and presenting radio, television and Internet programs about training entrepreneurial skills, establishing the extension entrepreneurial associations in rural areas and conducting technical and professional training and skill training in villages are among the important issues in the field of extension training programs affecting the creation of progress motivation among the studied rural women entrepreneurs. In other words, through these factors training skills and more specialized skills can be seen among the people of a society. The studied individuals stated that if conducting training classes on different parts of entrepreneurial field (skill training, idea training, marketing, sales, psychology of work and etc.) many of their problems will be resolved, in other words, the basis for supporting individuals will be provided and as a result their motivation will increase to continue work and its development. Also, economic conditions were another determining factor that in this study its relation with progress motivation of the studied rural women entrepreneurs is confirmed with structural model. In this context, important cases such as ease of collateral condition and valid surety to access bank facilities, access to appropriate market for selling products and access to financial resources for the considered business can be mentioned. In this context, it can be said that one of the most important affecting factors on creating and developing every new business is the financial factor and then the financial facilities (loan) that can be received in that field. Access to these cases will have a significant impact on motivation for start, creation and development of the considered business by the rural women entrepreneurs, and in other words, their motivation for progress. Therefore, in order to emerge and increase the motivation of progress among rural women entrepreneurs in the studied regions, it is suggested to consider special facilities for women entrepreneur to create and develop a business. Also, by determining selling market for the products of individual’s business and eliminating intermediaries and brokers and earning real profits by the entrepreneurs, it would be possible to see the multiplied increase in the individuals’ motivation.

Introduction
Investigation morphological of rivers is essential for understanding current conditions and the potential of possible changes of the river in future. Measurement of the geomorphic indicators is one of the methods that can provide the extremely helpful for understanding these changes. In the basin of Talvar the existence of the beds changes has created the issue of research.
Study area
The area of the river basin Talvar in Kurdistan province, with a total area of 7,241 square kilometers, is geographically located between 48˚ 06 ́53 ̋ to 48˚ 12 ́ 48 ̋ East and 34˚ 54 ́ 20 ̋ to 36˚ 00 ́ 10 ̋ North. This basin is one of the sub-basins of Ghezel Ozan drainage basin, located at the southern end of the basin, east of Sanandaj. The Talvar drainage basin is one of the sub- basin of drainage basin of GizilOzan that is located at southern part of this pool and north east of Sanandaj. In this study, due to the wide extent of the basin, and also to get more accurate results, the basin of Talvar was divided into 15 sub-basins.
Materials & Methods
In this study some of important indexes are calculated which included: Sinuosity index (S), Shape basin index (Bs), Asymmetry factor of a drainage basin (AF), Drainage density index (P), Branching ratio index (BR), Time of concentration (Tc), confluence angles.
For the calculation of the time of concentration was used the Kirpich equation. For measurement of the confluence angles was used the Digimizer Software. At the end, data was implemented model of Cluster Analysis in the SPSS software.
Result and discussion
Check the value of the S: In the active tectonic areas river is in the form of direct line. If S is low and Closer to the number 1, is represents the tectonic activity in the area. In the study area all of the sub-basins are equal to 1 or close to 1. So all are rated tectonic activity. The amount of S of sub basin number 12 is most of the others. Check the value of the Bs: The Bs value that is larger than the number 2 is indicating longitudinal basin. Lower amounts of it is indicating weak tectonic activities. So in the 1, 2,5,8,9,10,14,15 sub-basins, tectonic activity are high. 4 and 5 sub-basins are medium. 3, 7,11,12,13 sub-basins are weak. Check the value of the AF: The AF indicator is one right way for determine tectonic tilting overload on the scale of the drainage basin. In a sustainable environment, AF should be about 50 that show the perfectly symmetrical drainage basin. So none of the sub-basins are not symmetrical. Check the value of the BR: BR in normal drainage basins is 3-5. So except for the sub- basin No. 1, all other sub-basins are normal. Check the value of the P: High density factor show active tectonic and the high sensitivity of the geological. The lowest value of the density related to sub-basin number 5. Check the value of the Tc: Usually the amount of Tc in a circular basin is shorter. But the stretches basin Tc is more. Maximum value is related to the 1 and 5 basins. Minimum value is related to the number 3. Check the value of the confluence angles: According to the calculations, 2 and 4 sub-basins has the highest average amount of angle and 5 sub-basin has the lowest.
Conclusions
Dendrogram corresponding to s shows that 12 and 13 sub-basins are single groups in terms of high s. and other basin are in a cluster. According to the dendrogram corresponding to BS 1, 8, 14, 15 sub-basins are in a cluster. 3, 12, 13 are in a cluster. 2 and 9 are in a cluster. And 4, 6, 7, 10, 11 are in a cluster. Dendrogram corresponding to AF shows that 1, 6, 14 sub-basins are in a cluster. 5 and 8 are in a cluster. 7 and 10 are in a cluster. 4 and 11 are single groups. And other sub-basins are also fitted up a single cluster. According to the dendrogram, 1 sub-basin is a single group Due to the high coefficient of divergence ratio. 14 and 5 that are longitudinal sub-basins, are in a cluster. 2, 7, 15 are in a cluster and other sub-basins are in a cluster. The density dendrogram shows that 6 and 7 sub-basins that have a high permeability and multiple faults, are in a cluster. 5 and 12 are single groups in terms of relative poverty the density. 1, 4, 10, 13, 14 are in a cluster and other sub-basins are in a cluster. According to the dendrogram 1, 5, 15 sub-basins that are longitudinal sub-basins, are in a cluster. 2,3,10 are in a cluster. Number 7 is a single group. And other sub-basins are in a cluster. The average of confluence angles dendrogram shows that sub-basin 5 is a single group. 6 and 7 are in a cluster. 11,13,14,15 are in a cluster. 1, 3,8,9,10,12 are in a cluster. 2 and 4 are in a cluster. Accordingly, faults caused an increase collision angles. All indicators shows active or relatively tectonic in most sub-basins.

Abstract
Evapotranspiration is one of the critical parameters in the planning and management of water resources, especially in the agricultural sector. In this study have been discussed to review the reference evapotranspiration from the perspective of main factors its aggravating, with an emphasis on pressure systems in the warm season over the period 2014 1985 in the South West of the country. For this purpose at first, reference evapotranspiration calculated and then correlation values with the parameters of temperature, radiation, humidity and wind were calculated and finally to review of pressure systems, the average data of sea level pressure, zonal and meridional wind from the June to August in the period of 1985 - 2014 provided and maps were drawn. The results show that the correlation maximum of the reference evapotranspiration with wind parameter obtained So that in more than half of the studied stations, correlation coefficient has been more than 0.90 and almost at all stations (except station in Bushehr and coastal Bushehr) was more than 0.80. Among the parameters, moisture in many stations has had negative correlation with evapotranspiration. The radiation parameter than temperature parameter the more positive correlation has experienced in most stations. Review of pressure systems summer at sea level pressure indicates that the interaction of the western tongues monsoon low pressure system and eastern tongues Azores subtropical high pressure on the East Mediterranean sea is as the main factor of pressure gradient on the Middle East, including the South West of the country. That resulted northwest prevailing wind flow from the eastern Mediterranean conduct to the study area. As well as the prevailing wind flow in the study area from June to August, has been the Northwest. Cause of Strengthen and increase the wind speed and the result has been an increase in evapotranspiration, which would be a serious risk, especially in enhancing crop water requirement is due to the limited available water.

Abstract
In this study, in order to identify the status of health and educational indicators in the west coastal area of Guilan province, at first, the information of the above indicators for the three census periods of 2006, 2011 and 2019 was received from the Guilan governor's website. Then, using the Rural Development Index (RDI), Combined Result Index (CRI), Global Moran I, Local Moran I Index and cluster analysis, the extent of development and spatial distribution of indices in 8 coastal parts were determined. The results showed that the amount of RDI calculated based on the frequency and also the ratio of the frequency of indicators to the number of rural in each section, has a spatial difference. The Moran I Global Index indicates the clustering of the distribution pattern of boys' and girls' guidance school schools and boys' high schools. Also, RDI spatial analysis based on local Moran’s I index indicates the cluster pattern of HH, LL and LH and HL Outlier clusters in some indicators such as health center, health house, bathhouse, rural nursery, primary school and girls' guidance in different years. Also, the results of local Moran’s I on the CRI index indicate the Outlier clusters formation of HL and LH in three of the six cases. In this regard, CL analysis of health and educational indicators obtained from RDI showed that temporal and spatial shifts in cluster components (parts) have occurred over time. But the grouping of the CRI index has also been fixed spatially and temporally. According to the test of null hypothesis based on the none significance of a specific pattern and uniform performance of the index in the study area, it was found that the alternative hypothesis was approved and there was a significant difference between different sectors in terms of development.

Abstract
The changes caused by the rapid growth of urbanization have faced cities, especially metropolises, with serious economic, social, environmental and infrastructural challenges and issues. In this regard, the City Prosperity Index has been proposed as a broad conceptual framework for measuring development and human and social welfare, in relation to the quantity and quality of urbanization. In this research, with a descriptive analytical approach and with the aim of measuring and evaluating the condition of infrastructure and the factors affecting it in the four regions of Ardabil, the effects of this index on improving the City prosperity index have been investigated. To achieve the research goal, 28 sub-criteria have been used. The information and data required in this research have been collected using library resources, statistics of 2016 and also referring to relevant institutions and organizations. For analysis, the data were standardized and the network analysis process (ANP) was used to weight each of the indicators. Then, using R statistical software and Prometheus multi-indicator decision-making method for City prosperity, each of the four districts of Ardabil was scored. The results show that districts 1 and 2 of Ardabil city are in a relatively weak condition in terms of having an City prosperity index based on the infrastructure component and districts 3 and 4 are in a weak condition and due to the concentration of facilities in the central districts of the city, City prosperity is reduced from the city center to the suburbs in all four areas. Also, the ranking of regions shows that regions one and four, with a score of 52.39 and 48.64, respectively, have the highest and lowest City prosperity in terms of infrastructure.

Abstract
Development-driven projects are the context in which urban regeneration can revitalize the fabric. The implementation of these projects, while creating functional-social vitality and revitalizing urban identity and heritage, strengthens economic structures and attracts large investments in the area of worn-out urban structures. For this purpose, in this research, the stimulus project for the development of Imam Ali (AS) Square in Isfahan has been studied and evaluated. The research method is descriptive-analytical and applied in the framework of positivism and with inductive approach. The method of data collection is library and field. The statistical population of the study includes urban management experts in the study area and residents, businesses and other people passing through the area of Imam Ali (AS) and the sample size is 266 people for citizens and 30 people for experts. Data analysis methods include confirmatory factor analysis, central mean parameter and T-test. The results showed that the evaluation model of development stimulus projects consists of five dimensions. These dimensions include social, economic, physical, environmental and spatial sustainability indicators. Also, the results of the analysis of experts showed that the model has validity and each of the factor loads indicates the high validity of the five components. Also, the analysis of residents' opinions showed that the project stimulating the development of Imam Ali Square (AS) in terms of social and physical factors with averages of 3.65 and 3.37, respectively, has had a somewhat positive effect; But its impact on other aspects of regeneration, especially economic and environmental variables has been less.

Abstract
One of the main concepts studied in geographical sciences is geographical space. Each of the different dimensions of space forms a subject in this science field. Humans have been creating artificial changes in the geographical environment for many years by creating built environments. One of the crucial dimensions of space is the physical dimension. As a built geographical space, the university has a conspicuous role in developing students’ individual and social personalities. Many of students’ interaction emerges on the campus. According to spatial justice, women should have an equal right to presence in public spaces. One factor diminishing their presence is the improper design and non-responsivity of the environment to their needs. This study aims to provide a framework to improve the status quo of university campus open space in Iran and increase spatial justice by creating equal presence opportunities and answering these two questions: What is the difference between the needs of men and women concerning the environment? And what are the Factors of a responsive environment to meet the different needs of the two sexes? For this purpose, four areas of “The factors of public space quality,” spatial justice,” “spatial rights of users,” “sex and gender-based needs” were extracted from the existing literature and examined by qualitative content analysis. After matching the texts and finding common internal meanings, analyzing and separating, integrating them, and obtaining the fundamental factors, CVR and CVI questionnaires were sent to ten experts to check the necessity and relevance of each obtained factor and criterion. After performing the calculations according to the experts, the necessary corrections were made and a new conceptual framework in three general physical, functional, and perceptional dimensions and in the five components of “security,” “accessibility,” “comfort,” “diversity,” and “aesthetics,” along with criteria and sub-criteria; as the “results” of research; Explained. This research helps architects, designers, planners, and policymakers design an environment that responds to the needs of all students. As a research agenda, this framework could also be the starting point for further empirical research for future researchers.

Explaining the geostrategy of the Islamic Republic of Iran navy in the Asia-Pacific region
Abstract
In recent years, the Asia-Pacific region has absorbed great attention by various countries ,due to the importance of waterways in the global economic system and especially maritime countries . Also due to resource constraints and optimized strategic management, these countries have to have a geostrategy in the region. The purpose of this study is to explain the geostrategy of Islamic Republic of Iran Navy in the Asia-Pacific region. The present study is one of the qualitative researches of the foundation data type. The statistical population of the present study included experts aware of the subject of the research who were identified according to the subject of the research, experience and necessary knowledge. In order to identify these samples, purposive sampling method was used. This sampling continued until the theoretical saturation was reached and finally 14 people were identified as samples in the qualitative section. The results of the present study showed that the model of geostrategy development of the Islamic Republic of Iran Navy in the Asia-Pacific region in the field of crucial factors including principles, policies and strategic documents, the internal environment of the Islamic Republic of Iran Navy Information resources, history of national and international cooperation, individual factors, laws and regulations, cultural issues, organizational support, expertise and motivation. Background factors also include the marine environment of the Asia-Pacific Basin, the geopolitical situation of the Asia-Pacific Basin, human geography, economic, domestic politics, international politics, and military-security. Interventional conditions also include macro and micro factors.
Keywords: Geostrategy, Geopolitics, Islamic Republic of Iran Navy , Asia Pacific

Abstract
Introduction
Because of globalization and cultural globalization, local and national identities getting deformed. Have been lost their originality and social interaction, places transform to the planeness Relph stated that this placeness have qualities like biformal, sense of none formality, deforestation of places.
Since tourist are tend to visit urban spaces that are unique and have different qualities, so, the repetitions of other communities urbanism patterns in urban areas would have negative effects on attraction of urban spaces. So, there seem to have need to put local pattern and values in cornerstone of urban policy. Thus, urban spaces are required to be context friendly to be more competitive and attractive.
Besides, since there is a critical demand for shopping malls and restoring classic Bazzars, cultural transformation of time passing, dominance of classicity and new needs of communities including tourists, it is logical to offer contextualism pattern in such spaces. Unless there would be such a new pattern, it can be deteriorated function and branding of the spaces. Getting the pattern, it is required to empirically test its impacts on brand equity of Lalehpark shopping center. As if it would have positive on brand equity it would be recommended to apply this pattern for designing such shopping spaces.
Materials and Methods
Aiming to sort out particular problem of the society, the research is considered as applied one. The method is considered as mixed method which firstly thematic method (as a qualitative method) were included in the research. For doing thematic analysis for getting contextualism pattern for modern shopping centers, interviews were done and in 9th interview theoretical saturation were recognized in the research process. In this phase, thematic analysis started to work and after initial coding, it is required to mix the codes. The mixed codes forms main and sub themes. By making sub theme, the codes have hemoginity categorize in same main theme, and then by using the components extracted of it for contextualism its impact on brand equity were examined by structural equation modeling . the appropriate software were determined for executing such a modeling was Smart-Pls. doing explanatory factor analysis, data were inserted to Smart-PlS to have firstly some tests on validity, reliability, T-valueand based on them three items were removed to have valid results.
Discussion
The results shows that there is a positive impact of contextualism on brand equity by .767 route coeffienct, as well there is such a positive impact between contextualism contextualism i.e. symbolic contextulaism, convergence contextualism and geographic contextualism and brand equity variable. The results imply that in order to have a great brand equity in such shopping centers it is better to practical execute of the pattern in such shopping centers. As well, the results indicate that to have attractiveness in such shopping centers it should include some historical and cultural values in designing.
Although the research made some different pattern for shopping centers that have not ever offered but there is a similarity with background researches such as Merriles and etal and Eladly.
In spite of having some good features such as its attractiveness, publicity, offering well-known brands, there would be some recommendation for its improvement:
1-making bus line and sub way system terminated to Lalehpark.
2- Have more cultural events in the shopping center.
3- Completing shopping center projects surrounded to Lalehpark and harmonize them with Lalehpark as distinctive building based in the area.
4-offering spaces for youth such as sitting areas or reading areas.
5- Prioritizing low income individuals demands and offering affordable products.
6- Making separation of food court and path to have more calm and safe place for serving food.

Abstract
Introduction
Over time, land cover patterns and consequently land use change fundamentally. In order to make the best use of natural resource capabilities, it is essential to obtain accurate information about land use potentials. Kojoor region was registered as one of the most valuable regions of the country in terms of gene and species diversity in the list of the network of protected areas in the world by the approval of the High Council of Environment in 1967.Therefore, in order to protect this area, not only proper knowledge of human factors, but also the role of natural factors such as vegetation is very important.
Data and methodology
In the present study, Landsat satellite images were used in 7 time periods. EVI, DVI and NDVI indices were used to study and analyze vegetation changes in the study area.
In the present study, based on the modeling objectives, the study of changes in forest cover in the study area has been performed using Landsat satellite images (4, 5 and 8) for the years 1985, 1990, 1995, 2000, 2010, 2015 and 2017.
The false color images of the OLI sensor used were referred to the panchromatic band with 20 ground control points and observing the appropriate RMSe (0.28) of the ground. Then the images of MSS and TM sensors were referenced by image-to-image method with RMSe less than 0.5 ground. In this regard, the transfer potential modeling was performed with a learning procedure algorithm based on Multilayer Perceptron and prediction of changes for the best model was performed using Markov chain. Then it was used to evaluate the accuracy of modeling with Hit, Misses and False alarm statistics.
Discussion and conclusion
The results of the study of vegetation indices showed an improvement in the condition of cover in the study period. The results of the study of vegetation indices showed an improvement in the condition of cover in the study period. The study of land use also showed that with the current trend, the area of uncovered land will be reduced and the area of rangeland and forest cover will be increased. Therefore, the improvement of the coating conditions can be attributed to the application of protective operations.

Abstract
In order to investigate the atmospheric mechanisms governing the occurrence of the Von phenomenon at the time of forest fires in northern Iran, four types of data were used in the research. First, by taking the statistics of fires, the forests of the north of the period were identified. The monitored data of temperature, pressure, and wind in the front and back slopes of the Alborz mountain range were examined, as well as the networked data related to the National Environmental Forecasting / Atmospheric Science Centers (NCEP / NCAR). The European Center for Atmospheric Prediction (ECMWF) was used to explain the structure of the atmosphere. Modis sensor images were used to investigate the surface temperature and a suspended particle regression model was used to track the air mass. Studies have shown that with the formation of hypertension in the south of the country and low pressure in the north of the Caspian Sea, a strong pressure gradient is created and causes the southern currents in the northern regions of Iran to be affected. So that with the rising of the air mass on the Alborz mountain range and evacuation of its moisture and then passing the air package over the mountain and the heatless heat resulting from that hot and dry air mass has entered the region, these conditions are accompanied by strong winds and areas Susceptible to fire. Studies show that there is a sharp temperature difference between the windward and backward areas of the mountains, which is due to the unreasonable decrease and increase of air closure in the region. Airborne tracking also indicates that the main source of current entering the region is in the northern Persian Gulf and Northeast Africa.
