Abstract
Old trees as the most important genetic reserves of the country have great importance and value in various aspects of ecology, forest restoration management, ecotourism and even history. In this research, after identification of the old trees in the forests of Ilam province, their morphological characteristics including DBH, trunk height, total height, crown length, min & max crown diameter, crown health, crown firmness, crown symmetry, Trunk health and trunk shape were examined. The selection of old trees was based on DBH criterion. After the forest survey, 43 old trees including 5 Petrocarya fraxinifolia, 5 Ulmus glabra, 11 Fraxinus rotundifolia, 3 Celtis caucasica, 4 Platanus orientalis, 4 Ficus carica, 7 Olea europea and 4 Cupressus sempervirens were identified. The results showed that among single-stranded trees, P. orientalis had the highest mean DBH (171 cm), total height (15.8 m) and trunk height (6 m), and among multi-stranded trees O. europea had the highest mean DBH (260 cm). P. fraxinifolia and U. glabra had the highest mean of crown length (11 m) and F. rotundifolia had the highest crown area (195 m2). The highest percentage of single-trunks belonged to the P. fraxinifolia (80%) and C. caucasica (67%). The highest percentage of healthy trunks belonged to C. sempervirens (50%) and O. europea (50%) and the highest percentage of healthy crowns belonged to P. fraxinifolia (100%), C. caucasica (100%), P. orientalis (100%), O. europea (100%) and F. carica (100%). The highest percentage of crown symmetry was belonged to C. caucasica (100%) and the highest percentage of crown freshness was belonged to P. fraxinifolia (100%), F. rotundifolia (100%), C. caucasica (100%), P. orientalis (100%), O. europea (100%) and F. carica (100%). Based on the desirable morphological characteristics of old trees, it is possible to help the strengthen and restoration of Zagros forests by producing resistant seedlings from their seeds.

Abstract
The importance of studying development in the field of child psychology is crystallized. On the other hand, cognitive development is a source of awareness in the field of children's development and has a double effect on the process of wayfinding children. Paying attention to this in urban spaces can make it easier for children to successfully wayfinding. The purpose of this study is to develop factors affecting the ease of wayfinding children in urban spaces with emphasis on cognitive abilities. The research method is applied in the present study. In this regard, in order to collect data, field observations, questionnaires and site visits have been used. The sampling method is random using Cochran's formula and the questionnaire was completed by 106 children in the age range of 10-12 years and 106 children in the age range of 12-14 years. Data analysis to analyze the routing pattern of children affected by cognitive development in Lashgar neighborhood has been calculated quantitatively by factor analysis using LISREL software. In data analysis to evaluate the relationship between wayfinding and cognitive development after data collection, the data were analyzed by statistical methods of Ti-dependent test, Kolmogorov-Smirnov hypothesis test. Based on the analysis of cognitive abilities in the navigation process of children, the results indicate that the elements of the guide and used in navigation are different in two age groups, and the age group of 12-14 years has an analytical mind, and in contrast to the group of 10-12 years, it is searching and Paying attention to secrecy determines the path. Children in the second age range mostly mentioned the color of the facades, the shape of the building and the buildings that have a distinctive form and function, also the children in the first age range pointed to the distinctive signs that have a distinct body compared to other buildings in the neighborhood.

Abstract
Flood is one of the most destructive natural phenomena. Every year it brings extensive losses to the country’s financial and human resources. In our country, major parts of Iran’s provinces are always at risk of flooding. The Gorgan and Atrak catchments have also become more important, as several floods have occurred in Golestan province in recent years, causing many deaths and economic losses. The purpose of this study was to investigate the synoptic and thermodynamic conditions of the March 2019 flood event in Golestan province in order to atmospheric system that lead to such floods. This study includes statistical analysis of provincial stations (Gorgan, Gonbadkavus, Aliabadkatol, Hashemabad, Kalale, Maravetape and Bandaretokman), calculating of the return period of precipitation during the available statistical period of each station, analysis of synoptic maps on the day of the flood event, the analysis of satellite images of the days involved in the flood, and calculation of instability indices of the Gorgans’s station. Statistical results showed that Gorgan and Gonbadkavus stations, with the highest amount of rainfall in March 2019, had a return period with 800 and 400 years respectively. Also the highest amount index of Gorgan with values of K=26°c, PW= 0.27 cm and TT= 48 was obtained with high relative humidity (about 80%). The analysis of the synoptic maps showed the severe sea level pressure and mid- level height drop with a deep trough in the study area, which led to extreme rainfall.

Abstract
Vitality is one of the main components in design, but it is a complex and multifaceted concept that overlaps in its physical, social and economic dimensions. Therefore, in this paper, according to the theoretical vacuum of this concept in architecture and considering its interdisciplinary nature, using the model of various types of communication and types of vitality, the fields of psychology and sociology were selected for comparative study of vitality. Then, by using the comparative method by juxtaposing the differences and similarities of vitality in the field of psychology and sociology with definitions in architecture and urban planning, as well as examining the difference between vitality and other similar concepts in architecture and urban planning, including quality. Life, viability, and sustainability were ultimately represented by the definition of vitality and the model of environmental vitality. Therefore, the present study was performed with interpretive paradigm, qualitative approach, comparative method and logic of deductive reasoning, which is explained in terms of theoretical purpose and type of results. The purpose of this study is to answer questions about the definition of environmental vitality, the appropriate approach to research on vitality, the appropriate scale of vitality research, the factors affecting environmental vitality and its evaluation methods.
Key word: Happiness, social vitality, comparative study, environmental vitality
The results of this study show that environmental vitality is a relative concept of place and time that cannot be specifically defined for the vitality of all places in all countries and in all time periods, but rather Factors must be identified locally according to location. Factors affecting environmental vitality in general include experimental and aesthetic, functional and environmental components. The impact of each factor varies according to the culture and local characteristics of the place, which is due to the collectivist culture. And the place of collective happiness in our country, paying attention to the factors of vitality that increase the social aspects of space, attracting and involving people, can be a way forward.

Abstract
Optimal condition of accessibility and rapid, easy, and safe travel to health_ treatment land uses can be performed by the systematic analysis of transportation sub-systems like behavior. Developed countries are in essential need of proper transportation system for better accessibility. This paper aims to develop model, considering mode chains as well as the individual characters. This study benefits the analytic and quantitative research methods in developing mode choice model to evaluate the movement pattern of travel to health care centers in Shiraz central district (district 1). Each mode is the dependent variable whereas the socioeconomic characters are the independent variables. Filled questionnaire and geographical information system is used in collecting data. To generate the model, multinomial logit model was used that shows public transport like metro and bus are not the popular modes in access to hospitals. Movement pattern cognition in accessibility to special urban land uses, has an efficient role in urban policies and planning, which can be generalized and indigenize to healthcare travel behavior in other geographical areas. Results show that car ownership will increased the private car travel rate 8 times according to beta coefficient.. Taxi is the mode which is used in all three travels. People with lowest range of income and education use bus as their mode. Besides metro travel also has significant relation with low level of income and increase the travel rate 9 times.

Abstract
The purpose of this article is to analyze the frequency and severity of the one to six days of rainfall in Iran. The trend of frequency changes and severity of each course was identified using my-candle test and the slope estimator during the 1968-1988 period. Then, using the main component analysis method and cluster analysis method, the entire stations were categorized in five clusters (abundance) and four (intensity) based on the annual changes of frequency indicators and intensity of precipitation. Cluster 1 and 2 stations represent the frequency of precipitation periods with a severe or without trend. The two clusters were mostly established in the southern half of Iran. Cluster 4 and 5 stations represent the frequency of precipitation periods with a positive (mild) trend, mainly in the northern part of the country. Cluster 3 stations represent the frequency of precipitation periods with decreased (mild) trends, which are mostly focused on west and southwestern Iran. The clustering results of the stations based on the intensity index of precipitation periods, contrary to many results; do not show a specific pattern. But in the cluster, there has been a severe decrease in the last half century. The stations of this cluster are mostly concentrated in the northern parts of the country. Other clusters are scattered in almost all parts of the country. Accordingly, it can be concluded that the frequency of precipitation periods in the northern latitudes of incremental processes (average or weak) and the severity of precipitation periods in these latitudes (north of the country) had severe declining trends.
Keywords: Frequency of precipitation, intensity of precipitation, analysis of main components, clustering, process.

Abstract
One of the theories that studied poverty and inequality after World War II and urban reconstruction in America in the duality of the suburbs and the central city is the theory of Spatial Mismatch. Despite the role of the background caused by racial-ethnic inequality and the contrast between the suburbs and the central city in the formation of the aforementioned theory, the main indicators of Spatial Mismatch indicate the lack of appropriateness between obtaining a job with sufficient benefits to access affordable and quality housing. This means that the backgrounds, structures and processes of inequality are different from one society to another and the lack of proportionality between the benefits of work and access to housing represents the spaces of poverty. The aim of the current research is to reveal the Spatial Mismatch between the two mentioned indicators in the metropolitan areas of Tehran. The current research is applied research in terms of its purpose and descriptive-analytical in terms of its method. The main data required include major occupational groups and housing status in official population and housing censuses, which have been analyzed using spatial functions. The analysis of the research findings shows that there is a direct relationship between occupational stratification and the quality of residence in Tehran's municipal areas. In such a way that the concentration centers of the lower classes and workers who are deprived of jobs with suitable benefits have been formed in residential areas with poor quality and worn-out textures. Based on this, in the southern regions of Tehran, there is a greater disproportion between getting a suitable job and access to quality housing. While in the northern areas of Tehran, there is much more suitable work and access to quality housing. The final result shows that the two main indicators investigated well reveal and represent the «Spatial Traps of Poverty» which are the main focus of Socio-Spatial Issues in Inner City Areas.

Abstract
Access, plays an important role in rural development as there is a meaningful relationship between rural development and access to infrastructure services. Villages that have less access to essential services, especially transport, faced with a lot of structural and socio-economic constraints, which are obstacles to sustainable rural development. The present study seeks to examine the accessibility and the factors affecting it. Accordingly, it is considered with descriptive-analytic research method. The statistical population of the study, consisted of villages in the central District of Tabriz County (52 villages) that there needed data were gathered from rural municipals. After validity and reliability of the research, in order to evaluate accessibility, we used the Dematel technique and ANP, then to assess the role of different elements in accessibility of rural areas, we used SEM in Amos software. Initial results of Rural Accessibility Survey showed that the Mayan Sefli village had the highest accessibility and the final result of the research are determining the role of factors in rural accessibility based on factors such as distance from the city, service centers and social status of the village are more effective than other factors in accessibility.

Abstract
Increasing energy demand and environmental problems caused by the consumption of fossil fuels have made the use of passive solar energy methods more necessary, especially in commercial centers. On the other hand, the growth of science and technology in the world and the use of intelligent systems in buildings, has led to the completion of common methods. The purpose of this study is to investigate the role of the side wall of atriums and building intelligence in optimizing energy consumption in commercial centers of Tehran. Due to its nature, the research method is simulation with a case study and analytical approach and in terms of application type. In this research, first, the typology of the building form is introduced and the basic model is selected, and after selecting the design-builder software, validation and simulation of energy consumption in different scenarios are performed to determine the reduction of energy consumption in different situations. This research, which is taken from a doctoral dissertation, shows that the most optimal commercial centers in terms of reducing energy consumption in the climate of Central Tehran are related to atrium buildings without side walls. Also, the installation of smart awnings and light sensors at a control temperature of 22 degrees has significantly reduced energy consumption in these buildings.

Abstract
Along with the development of cities and increasing population, many challenges have been created, the most important of which is urban transportation. The inability of traditional urban management to address this challenge has led to some approaches, including intelligent transportation. Adopting and implementing such an approach in metropolitan areas requires a change in management approach, of which integrated urban management is known as the most important. The purpose of this study is to investigate the status of integrated urban management and then its impact on the realization of intelligent transportation in the city of Zahedan. The research method is descriptive-analytical and based on data collection in the field through a questionnaire. The validity of the instrument and its reliability was confirmed by Cronbach's alpha greater than 0.70. The statistical population of the study is urban experts in Zahedan. The sample size was set at 100 people. The result of the one-sample t-test shows that the variables of integrated urban management are significant at the level of less than 0.05. From the statistical point of view, the 7 variables of good governance, synergy, unity of urban command, context, interaction, organizational structure, and systemic perspective are not in a good situation and these conditions have caused the integrated urban management index in Zahedan to not have favorable conditions. Also, the significance of the test shows that the 5 variables of intelligent transportation, namely intelligent monitoring, intelligent payment, intelligent violation registration, intelligent information, and mechanized fleet management are significant at the level of less than 0.05. Significantly, it indicates the unfavorable situation of the intelligent transportation index in Zahedan. Regression showed that integrated urban management variables can be more than 68% effective in the realization of intelligent transportation and 32% are dependent on other factors. The variable of good governance with 12% and then the systemic perspective with 11%, has the greatest impact in this regard.

Abstract
Today, with the expansion of urbanization and the increase in the population of cities, urban poverty is one of the important problems that it seems necessary to fight. In the 21st century, one of the indicators of urban progress is the issue of low urban poverty (Lemanski and Marx, 2015). In order to analyze and evaluate the indicators of urban poverty in Rasht city in different blocks and to cluster social poverty in this city (very poor, poor, average, wealthy, very wealthy), to analyze social poverty and extract spatial hot spots from Arc software. Gis was used. And the extraction of different areas of the city was calculated from the R software and by the multi-indicator Prometheus decision-making method, where the weight of the indicators was obtained by the ANP method from the raw data of the statistical blocks of Rasht city in the census of 2015. The findings of the research showed that comparatively, the central parts of the city are covered by medium blocks, and in the outer and peripheral parts of the city center, two hot spot areas are observed, which contain very prosperous blocks. Cold spots are also clearly visible on the outer edge of the city and they cover very poor and poor blocks, and except for the hot and cold spots, the city is mostly in the form of mild spots and most of the blocks are in poor condition. They are placed in average social poverty. Also, based on the findings of the research, most of the deprived areas in terms of social poverty in Rasht city are located in the north-west and north-east parts of the city.

Abstract
Cities are open systems that constantly change and bring about changes in inside and outside neighboring areas. With the rapid growth of urban population in the world, cities sprawl and occupy surrounding lands. In this situation, attention to the developments inside urban space could be a key principle in urban planning. The aim of this study was determining and prioritizing economic, social and ecological factors which influence inside urban space indicators in City of Gorgan using Delphi method and literature review. Following the increase in population, developments inside urban space in the future is inevitable. Understanding and recognition of this process is essential to effective management in the field of conservation of the urban environment. Four expertize requirements should be taken into account: knowledge and experience of the field of study; ability and willingness to participate; adequate time to participate; and effective communication skills. Experts’ panel included fifteen specialists from municipality, city council, academics, cultural and medical service providers, police, urban planners and citizens, whose points of view were collected using questionnaires. Data collection for questionnaire was repeated 4 times to reach a consensus. Overall, twenty - four factors were identified for the economic, social and ecological factors, and then the degree and percentage of importance for each one was determined. Results showed that the most important indicator is feeling of security followed by the noise pollution and environmental pollution. Results could be helpful to urban planners and related organizations to improve inside urban space for welfare and life quality of citizens. Prioritization of these indicators provides an appropriate action agenda for the managers.

Abstract
The present study investigated the impacts of NAO and ENSO on the precipitation in the southern shores of Caspian Sea. The accumulated monthly and annual rainfalls from 5 synoptic stations during the years (1956-2017) were taken through Islamic Republic of Iran Meteorology Organization (IRIMO) and the Multivariate Enso Indices (MEI) and NAO activity years are obtained from National Oceanic Atmospheric Administration. Pearson correlation was used to investigate the relationship between indices and precipitation amounts of selected stations. The results showed that there was a significant relationship between precipitation and NAO index in some months in all stations but this correlation was not following a particular pattern in all the stations. The maximum correlations were observed at Babolsar and Anzali station and the least correlation was found at Gorgan stations. The correlation between precipitation and different phases of NAO showed that there was a positive correlation between precipitation and negative phase of the index in Ramsar station and a negative correlation between precipitation and positive phase in the Gorgan station.The results of the Pearson correlation show a significant correlation between the MEI and rainfall amounts in the autumn in some stations in the early winter. In Review drought and wet periods with both Indicator it was observed that the behavior of the stations in the El Niño period, which was with different phases of the NAO was not entirely harmonious but the coefficient of 89% of rainfall in normal and more than normal during the period of El Niño showed that Elnino is better fitted to normal and more than normal rainfall in these stations also coefficient of 60% of weak to severe droughts in the Lanina period in the selected stations Indicates that the LaNina phase was more related with severe droughts in the under studied period.

Abstract
The continuous and active presence of disciplinary centers has an important role in ensuring security and peace in cities.Therefore the fair and efficient distribution of law enforcement centers in urban areas is an important factor in meeting this basic need.Therefore, the present study aims to investigate the service of police stations on vulnerable areas of Urmia.The descriptive-analytical research method used in this study is applied.The results of the study show that the vulnerability zoning of the city of Urmia is in four categories from very high to very low. About 68 km2 of the whole area of the city is known to be highly vulnerable.Most of the northern (informal settlements of Region 2) and central (old districts of four region) settlements of Urmia are the most vulnerable areas due to the high density of population and housing,with most of the politically sensitive, commercial and administrative offices in these areas.The results of the network analysis based on standard time (12 minutes) indicate that the 28.9% (24 km2) of the Urmia Vulnerable Areas was not covered by the police stations.Within 12 minutes the police stations of Urmia city have quick access to 55 km2 of about 75 km2 area with high vulnerability and about 20 km2 of this area also without timely access. In terms of the police stations access to low vulnerability areas,the results also show that from about 15 km2 of these areas to 3 km2 have quick access, indicates that there is no quick access to these 12 km2
