Experiences acquired in the reorganization of the old structures and buildings of the countrysides and suburbs show that Iran and other countries in the world, have not been successful, because of the inability to build and define a perfect house. This research discusses about the proper indicators related to appropriate houses from the perspective of those who live in such areas. Descriptive and analytic methods have been used. North East outskirt of ​Mashhad was the study ​area because a large population live in this region. The question is: Why people prefer to live in a house with a yard instead of an apartment. In this study,  410 persons were questioned. The collected data through the years 1391 to 1393 were analyzed by SPSS software. The Study shows that age, the year of buying the house, the educational level and the type of house possession affects the suburbs population's views. Therefore, if the governments consider these housing preferences and divide those people into certain subgroups, providing accommodation for them would be more successful.

Assessment is one of the important methods in analyzing the accomplishment of Sustainable development and as one of the necessities of planning can identify potential and actual environmental effect that is emerged as a result of the construction and development and provides logical options to solve them.  The purpose of the current research is to assess the environmental effects of multi-layer highways on the neighborhood. The research is applied In terms of purpose and descriptive in terms of nature. Moreover, this research is environment based and uses sustainable development in theory. In order to analyze the data, 8 neighborhood around the Sadr bridge (Tajrish, Gheytariyeh, Chizar, Zargandeh, Sadr, Rostam Abas, Ekhtiyarieh and Pasdaran neighborhoods) were chosen as the analyze unit. Assessment indexes were assed in term of social, skeleton, vision and health-hygiene, economic and ecologic and safety-security domains. statistical Qualitative and quantitative  methods including  one sample T test and Friedman test were used to rate the domains and spatial analysis methods (spatial statistics) were used to show the status of the neighborhood. We also used the TOPSIS technique and Iranian Leopold in order to rate the neighborhood in terms of environmental effects of multi-layer Sadr Bridge. Results of the assessment matrix showed that Sadr multi-layer project is confirmed by providing corrective options in activities with high and very high damage. Based on the research findings it was found that the neighborhoods around the Sadr multi-layer highway given the assed dimensions, each have a different susceptibility from the multi-layer Sadr Bridge. In this regard, the ecological and skeleton have the most susceptibility and the security each have the least susceptibility from the Sadr multi-layer Sadr bridge and in rating the neighborhood, Rostamabad had the most susceptibility and the Zarhandeh has the least susceptibility from the Multi-layer Sadr bridge.  

Previous research has acknowledged the importance of human resources in service companies by influencing the end customer and has shown that if internal marketing succeeds, external marketing will also develop, but describing this development is beyond the reach of purely quantitative or qualitative studies. . In this regard, simulation can come with the help of the humanities and identify the factors influencing the development of internal marketing. In this study, using the systems dynamics approach, factors affecting the success of internal marketing were investigated. The statistical population is all marketing experts at Fiberglass. Primary data were obtained through interviews with them and secondary data from company documentation. Dynamic drawing and modeling and final loop identification through VENSIM PLE software Four key loops were identified for the dynamic internal marketing model that included customer orientation, knowledge, satisfaction and motivation. And the results showed that if the identified four loops were supported and developed, internal marketing would have a high growth. Among these factors, customer orientation became more important to be achieved by developing a culture of customer orientation in organizations.

In this study, the spatiotemporal variations of evapotranspiration (ET) were investigated in the southern part of the Aras River catchment. For this purpose, the ET networked data of FLDAS Noah model with horizontal resolution of 0.1 * 0.1 degree were used for a period of 38 years (2019-1982). After validating the data, the average annual ET values ​​for the region were determined first. Then the monthly and seasonal distribution of the parameter were analyzed spatially. Subsequently, ET variations and anomalies were evaluated year to year. Also, the spatial distribution of the occurrence frequency of ET was investigated by considering the absolute thresholds of 50, 80, 100 and 120 mm for the Aras basin. The results show that the annual ET in the east of the basin is higher than the west of the basin. In the seasonal scale, spring and summer have the highest ET values, respectively. In the monthly scale, Mayو June, April and March had the highest ET values, respectively. In contrast, the autumn and winter months have the lowest average ET values. Also, the whole basin during the study period has experienced three distinct periods of ET changes that in the eastern and western parts of the basin, despite the same behavior in the second and third periods, a significant difference was observed in the first period. The results also indicate the existence of positive anomalies after 2002 in the whole basin, the highest values ​​occurred in 2018 in the west of the basin. The study of the frequency of occurrence of absolute ET thresholds on the basin shows the high frequency of ET occurrence at all thresholds in the east of the basin. A study of nearly 4 decades of ET values ​​in the Aras River Basin shows an increase in ET values ​​over the last two decades over the entire basin, which can be attributed to the occurrence of global warming.

The city development strategy(CDS) is a novel initiative that is currently being implemented in numerous cities worldwide, including several in Iran. Its primary objectives are to enhance the quality of life, combat poverty, promote sustainable development, and foster effective urban management through a participatory approach. The purpose of this study is to examine and compare the perceptions of residents and municipal administrators regarding various aspects of the urban development plan. This study is characterized as descriptive-analytical. The statistical population comprises managers, employees of urban management, and citizens in Yasouj city. The sample size was estimated to be 384 for citizens and 30 for managers using Cochran's method. One-sample t-test, independent t-test, one-way analysis of variance(ANOVA) and multivariate linear regression were used to analyze sample data. The findings of the study reveal that while municipal administrators are generally content with the current state of these dimensions, residents believe that these elements of the urban development plan are not satisfactory. The descriptive statistics and the t-test demonstrate that the overall mean of the urban development plan dimensions is 1.88 from the people's perspective and 2.98 from the viewpoint of urban administrators. Furthermore, the level of satisfaction with the research's dimensions significantly differs between the two groups. The linear regression analysis indicates that, according to the people's perspective, the dimensions of bankability and the ability to live comfortably hold the highest and lowest significance, with coefficients of 0.413 and 0.167, respectively. However, from the perspective of city managers, the dimensions of livability and good governance are the most and least significant, with coefficients of 0.373 and 0.112, respectively. Ultimately, the findings of this study can assist urban managers in making more informed decisions and delivering services that better align with the needs of the community.
