Abstract
In recent decades, developing urban tourism as one of major economic activities in different countries has caused many managers and planners to consider increased quality of tourism experience and protecting interests of host communities to expand the activities of this industry, knowing potentials, existing problems, decision making and planning. To do so, strategic planning can be propounded as a response to difficulties occurred due to lack of appropriate planning in tourism. In core tourism like all other commercial activities, strategic tourism should be depicted. So, one of strategic planning models used to develop tourism particularly urban tourism is a traditional model called SWOT. Therefore, in present study, it has been endeavored of Shahr-e-kord located in Chaharmahal-e-Bakhtiari as well as to analyze difficulties and problems existing in respect of Shahr-e-kord tourism. His study is a descriptive-analytic one and was done using filed studies and data gathered through evidence and libraries, questionnaires (considering the attitude of 70 officials and tourists) and Internet. Then, data was analyzed using excel software and strategic model of SWOT. Results suggested that due to having high capacities for tourism, Shahr-e-kord suffers from lack of enough infrastructure problems. On the other hand, it encompasses opportunities for educated young people to be employed and for investing. Some of major solutions to develop tourism are to increase advertisement, provide welfare and accommodation facilities, attract investment and be protected by government.

Abstract
Solid waste is an integral part of human life, generation of various quantities and qualities of which is one of the greatest environmental problems of the current era. Application of modern tools and technology to find the right place for recycling, where the volume of recyclable materials can be reduced, seems vital for reusing the recoverable materials contained in normal waste and their recycling and reusing in the cycle of industry. The study aimed to find a location for recycling and its converting industries in Kelardasht, Iran. This was a descriptive and analytical research with a survey approach. At first, experts of the field were recognized and a scientific panel was formed to identify the relevant criteria through Delphi method. In this respect, five criteria of the distance from residential and commercial areas, the distance from urban streets, the distance from the river, the distance from the hospital and education centers, and the distance from hotels, banks, and offices were selected. After that, the permitted distances for these criteria were determined by Delphi technique, followed by the application of the centroid method to determine the exact distances. Moreover, the analytical hierarchy process (AHP) and geographic information system (GIS) were exploited to determine the and use weights in raster maps and generation of the zoning map. Furthermore, the best locations for recycling were selected in Kelardasht using field survey method and based on the zoning map. According to the results, four sites were selected for recycling of recoverable solid waste in this region

Abstract
The term urban heat island (UHI), described the phenomenon of climate change in urban areas compared with surrounding rural areas. UHI effects include: increasing in energy and water consumption, air pollution expansion and interfering in thermal comfort. Surface urban heat island (SUHI) contains patterns of land surface temperature (LST) in urban areas that has interaction with UHI in urban canopy layer and urban boundary layer and investigate with thermal remote sensing. SUHI has diurnal and seasonal variations so requires multi-temporal data to analysis SUHI. In this study, the multi-temporal MODIS (Aqua and Terra) data product were used to analyze the SUHI in day and night in Tehran metropolitan. Physical and biophysical surface properties such as: land cover/land use (LULC), elevation, albedo, vegetation index (NDVI) and impervious surfaces index (NDBI) were used to interpretation of the LST and SUHI changes. The results showed that SUHI in Tehran, has spatial-temporal diurnal and seasonal variation. So that during warm days the surface urban cool island (SUCL) is formed in Tehran. At night times, SUHI index values was different between 2 and 5 ° C (maximum in the spring). The results also showed that different of land cover thermal properties, albedo and elevation was the most important factors is the diurnal changes of SUHI while phonological changes of vegetation and albedo, was the most important factors in seasonal changes of SUHI.

Abstract
Using the passive defense principles in urban plans and projects is important in the context of land use planning, reinforced concrete, citizen education, and increasing urban resiliency. Observing and adhering to these principles will reduce the vulnerability of the city and citizens to security and military threats. Therefore, this study aims at evaluating the spatial pathology of the physical and social structure of the 6th urban district of Tehran municipality with emphasis on passive defense approach principles particularly citizenship education principle. Therefore, this research has selected the 6th urban district of Tehran municipality, due to its important and sensitive land uses with regional and trans-regional functions as a research area. In this study, the AHP model was used to assess the physical structure pathology. In order to evaluate the social structure damages of the area, three neighborhoods were selected in the region using cluster-spatial sampling. Then, using the survey method, the authors sought to collect the views of the inhabitants. In order to determine the sample size, the Cochran's formula was used. The results of this study indicate that the vulnerability of the region in terms of the physical structure is moderate and downward. Additionally, the social vulnerability of the area is also above average. Finally, the factors influencing the vulnerability of physical and social structure were investigated. Accordingly, it can be concluded that the indicators of population and construction density are the most important factors affecting vulnerability from experts' viewpoint. In addition, it was revealed that education and awareness, resiliency against security-military threats, skill and expertise, respectively, are the effective indicators of the vulnerability of the social structure of the area.

Abstract
Population growth and urbanization development are the main triggering factors of changes in urban land uses. These, in turn, result in changes in the components of radiation balance. The present study tries to analyze the role of urban land uses in radiation balance by calculating net radiation and its analysis. For this purpose, the Landsat 8 satellite image of 2016 was used. Characteristics of radiation flux including net radiation flux (RN), ground surface albedo (α), incoming longwave radiation (RL↓), incoming shortwave radiation (RS↓), outgoing longwave radiation (RL↑), and ground surface temperature were computed using Sebal algorithm.The values of these components in different land uses (compressed residential, scattered residential, green area and wastelands) were analyzed using one-way analysis of variance (ANOVA) and Tukey’s test. The results of this study showed that the selected land uses have significant differences in the amount of radiation flux, therefore the wastelands are warmer than the residential areas by about 6 oC and the residential areas are warmer than the green areas by about 1.5 oC. The results also indicated that these differences are due to changes in output energy (α and RL↑), and any change in land use over time will ultimately lead to a change in the radiation balance and the temperature of those places, which this temperature increase, is different from the increase of the temperature due to global warming.

Abstract
The urban land management is an l part of the urban management. In some countries such as Iran, there is no integrated urban land management and providing municipal services is assigned to nationwide organisations. This means urban management is offered by the municipality or subsidiaries of the aforementioned organisations such dispersion has occurred during serval decades. It is considered as the roots of organizatinal inefficiencies ( offocial and financial corruption is regarded as basic reasin for many crimes) and the origin or many conflicts between people and organizations(judicial) To do so, it follows an applied analytical descriptive approach. To analyse the data, mathematical and statistical methods were applied using Excel and SPSS. Moreover, the GIS was used for visualisation and adaptive analysis. The study concluded that lack of clear visions and consequently uncoordinated organisations and their policies, isolated and vertical decision-making, and unmanaged intervention without the required organisational capacities are the critical reasons for inefficient urban land management.

Abstract
In public organizations such as municipalities, the design and deployment of a performance and control assessment system can lead to the proper management of urban managers on the road to achieving goals, tasks, strategies and development plans and urban development, in accordance with the quality, cost and time desired. Therefore, this article attempts to study the satisfaction of urban performance in urban services by using the views of citizens of the city of Farouj. For this assessment, using theoretical studies, 21 types of urban services were selected in three sections: Technical, Public and Cultural Services. At the next stage, the questionnaire was designed based on these services. Then, 400 questionnaires were distributed among the citizens of the case study city. In the next step, 380 questionnaires were completely and correctly collected and entered into SPSS software. Finally, the results of the study were analyzed by statistical tests. The results of the research indicate that the average satisfaction rate of public services in the city of Farouj is 3.53, which can be said that the level of citizens' compliance with this service is in the middle level. The average satisfaction rate of technical services in the city of Farouj has been calculated to be 3.31, and the average satisfaction rate of cultural services in city of Farouj has been calculated to be equal to 3.5. The results of statistical analysis indicate that the level of significance is more than 0.05 in relation to four of the urban services. This means that in terms of the services of sports spaces, the collection and disposal of surface water, the quality of leisure travelers and the respect of the clients, the level of satisfaction of citizens is equal to the average. In relation to two indicators of pedestrian quality and public participation, the mean difference with the statistical test was calculated to be 0.16 and -0.19 respectively, which indicates that the satisfaction of these services is lower than the limit on average. In other indicators, citizens' satisfaction is above average

Abstract
The horizontal and urban growth of the past few generations, due to the dominance of the centralized planning system in the country, has led, in accordance with the principle of village-to-city interconversions, that many villages located around cities have undergone numerous changes and changes in the indicator status Of development. These changes, in addition to having positive aspects in most cases, have had a negative impact on the sustainable development of rural areas located in the vicinity of these cities. In the current applied research, a quantitative and qualitative approach with a spatial and descriptive-analytic approach has been carried out. The main objective of this research is to identify the consequences of the Marivan Creep phenomenon on the changes in the development status of the surrounding villages, Over the last few decades, physical development has been speeding up. Data gathering in the theoretical part of the documentary and in the field was conducted by a survey method based on an interview with the local people and the locals to identify the outcomes, and then the classical distribution of the questionnaire among the studied villages and simple random among 203 households supervised by The Cochran formula was determined by volume, 30 from local development experts and observers of the status quo, in order to generalize the findings from the interviews. The results of analyzing the data with the fundamental theory of the technique in the qualitative section and the single-sample t-test in the quantitative section showed that the urban creep phenomenon, in addition to limited positive consequences in improving the physical condition, caused social deficiencies, failure Economic problems, inadequate visual quality, natural environment degradation and institutional management failures in the development of villages studied.

Abstract
Urban land utilize planning, for optimal use of existing facilities and urban spaces is one of the main cores of urban planning, which is usually defined as a multi-objective issue. In line with the absence of specific categorization, system for land use in Iran the use of metaheuristic algorithm and artificial intelligence is required. One of the algorithms that introduced and used in recent years are the optimization algorithm (BBO) based on biogeography. Current research is from practical research group and type of descriptive-analytic research, the data analysis method would be write and execute in MATLAB software by using biogeography algorithm. The purpose, after identifying most effective variable, will be to improve the present status of the system's distribution use indicators and their adjacency in the county surface. For comparing the results of current research, in terms of desired area needed uses with development plan of Semnan County, each dimension of (GIS) layer should be provide.overlapping of the layers would be compare with development design.

Abstract
The ‘Smart mobility’ has become an increasingly prevalent discussion topic in the past few years, not just in academic literature but also in cities’ policy and strategy. However,in many cities of the world and in our country, Iran has been associated with problems such as lack of citizen participation and inequality (caused by inefficient urban management). The present study has attempted with an innovative perspective to evaluate the existing infrastructure of mobility indicators (including transport infrastructure, public transport, sustainable transport, ICT) and the social dimensions of these infrastructures including the extent of citizen participation in use. Of these infrastructures) in eleven districts of Shiraz.The research method is descriptive-analytical and based on documentary and origin studies. Data gathering was field study by using a questionnaire. The 5-degree Likert spectrum technique was used to measure the value of indicators of the Smart Mobility. The results show that average smart mobility was higher in regions 1 and 6 than in other regions. the average smart mobility indicators are in 11 and 9 the lowest in other regions. The Urban Smart Mobility variable does not have an appropriate position in Shiraz, and this has not only affected its development process in recent decades, but also poses many challenges for its future development. Accordingly, urban planners should Consider the citizen participation and efficient urban management.

Abstract
The real world has been created of extremely complex mosaics. The regional analysis entails the study of the mechanism of the processes involved in systems that are capable to explain the emergence, growth and decline of a region, but like any other geographic research, doing comparison in such a study is inevitable. The cities of the world are now the homes of more than half of the world’s population. Perhaps the most important global challenge of our age is to make sure that whether the planet remains habitable and provides sufficient resources for future generations. In this study, a descriptive-analytic method has been used to analyze the effects of information and communication technology in urban sustainable development in west urban areas of Kermanshah province. The statistical population of the study consisted of 184642 people that 386 individuals were randomly selected as the sample. The required data were collected by documentary-library method and field study and analyzed and processed using SPSS software and variance analysis model. The results showed that the cities of Qasr-eShirin, Gilan-e Gharb, KerendGharb, Sarpol-e Zahab and Islam AbadGharb obtained the first to fifth ranks respectively in terms of the affectability from information and communication technology in sustainable urban development.

Abstract
The rapid growth of urbanization in recent decades and the neglect of qualitative aspects of human life have had adverse effects on the individual and social health of the community and urban life. Generally, life quality addresses social, environmental, and the economic issues. Plans should be consistent with improving life quality. On the other hand, improving the life quality can result in developments in social, economic, physical and service-providing areas. In this regard, the purpose of this study was to investigate the role of Malayer urban spaces in improving the citizen’s life quality including variables such as the quality of facilities in the city, social environmental, economic quality and environmental quality, , security and relaxation, and so on. The method used in this study was a combination of analytical and case-oriented methods. The type of the study was a developmental one and the area understudy was Malayer with 52697 households and an area of 2,400 hectares. Quantitative models and statistical procedures such as development indicators, standardized scores, correlation coefficient, t-test, multiple regression, variance analysis, coefficient of variation, factor analysis, and 60 variables as the indicators of this study were used to assess and evaluate the life quality in Malayer as far as social, economic, environmental and physical aspects of life were concerned. Using Cochran's formula, 384 random samples were selected from different parts of the city and were analyzed through descriptive and inferential statistical analysis using SPSS software. The obtained findings showed that the economic index of life quality with 58% was more inappropriate than the social, cultural and physical ones, while social and cultural indicators with 42% were in a moderate situation. The results also showed that the components of the quality of economic environment, working environment, transportation and the community are in an unfavorable condition in Malayer. Thus it is possible to increase the life quality in Malayer through improving the economic, social, cultural and relative access to urban services.

Abstract
The concept of the city's landscape is connected with the objectivity and subjectivity of that city. Therefore, in order to manage this concept at night, in addition to functional-physical manifestations of the city, we should focus on the perceptual issues of citizens, which may have roots in their ancient identity, religion and customs. By accepting this hypothesis, a suitable model for night-time urban landscape management should be considered as a model that reveals both the physical and functional aesthetics of the city, as well as the perceptual and psychological components of the citizens from the night view. Nowadays, with the expansion of night life, the concepts of the quality of the location of urban landscapes at night has became as important as day. The aim of this study is to evaluate the relationship between lighting and the sense of dependency that is one of the key factors in location's quality and the role of new lighting technologies in promoting the Social-physical concept of sense of dependency and its impact on the transformation of the environment into a more humane urban environment. The research is a survey in which, for data gathering, a questionnaire with different images of the study area has been distributed among the selected statistical population. The findings indicate that the vitality and subjective image's of citizens are directly related, and the amount of lighting and its color and the way of lighting have a positive effect on urban nightlife.

Abstract
Promoting urban livability and realizing a livable city are closely linked to how the urban management apparatus and institutions and organizations active in urban affairs function. Municipalities, as the most important coordinating body in urban affairs, have played a decisive role in solving urban problems and are responsible for the social and physical development of cities. In fact, municipalities have the main task of serving the citizens and play the most important role in improving the quality of life of citizens. The purpose of this study is to evaluate the viability level of Semnan city and analyze the problems of Semnan city from the perspective of different groups (officials-elites). The research method is descriptive-analytical and the research tool is a questionnaire. The validity and reliability of this research has been confirmed by the previous similar research and the opinions of the supervisors and advisors of the dissertation, the validity of the research tools. The internal validity of the instrument (questionnaire) is also shown through the Cronbach's alpha with a value of 0.84 for the questionnaires. The results showed that among the total biomarker indicators of Semnan city, from the point of view of elites and officials (with an average of 2.76), it was evaluated at a low level. Also, based on prioritization with ANP technique, "Improving Institutional-Organizational Capacity in Optimal Urban Management (R7)" with the highest score (07/357: 357) was identified as the best solution and in fact the main solution to deal with urban issues in Semnan. Also, the strategy of "integrated management between urban organizations to coordinate in the management of urban affairs (R6)" with (06/3366) was selected as the second solution.
