Abstract

A sense of belonging to an environment is an emotional connection that takes place between people and the external environment. Many studies have shown that the existence of this connection and its deepening between the person and the environment has a significant role in promoting the physical environment and the emergence of positive social behaviors. Therefore, recognizing the sense of belonging and the factors affecting it and ways to improve it is one of the issues that can lead to the improvement of living conditions and physical environment. Among the many factors that affect the sense of belonging, the time factor as one of these factors can be effective from two perspectives; Duration of residence and age of the environment. In this study, while researching the effect of each of these factors on the sense of belonging of residents, a comparison between these two factors and the intensity of the effect of each on the sense of belonging has been done. The present study is applied in terms of purpose and descriptive-analytical in terms of method. In order to collect the required data and information, library and field methods and questionnaire tools were used. The statistical population of the study consists of citizens living in the six studied neighborhoods in Zanjan. The sample size was estimated to be 300 people using the Cochranchr('39')s formula. SPSS software was used to analyze the data. The results showed that the sense of belonging in the study areas is moderate to low. The results also showed that the duration of residence and the age of the environment have a positive and significant effect on the sense of spatial belonging and its components. Among the variables, the effect of the environment variable on the sense of spatial belonging is greater than the length of stay, so that the age of the environment predicts 27.1% of the variance of the variable of spatial belonging.

Abstract
Climate change is an important environmental issue because the melting processes of glaciers and snow density are sensitive to climate change. Today, a variety of satellite sensors such as AVHRR, MODIS, GEOS, MERIS are available for snow monitoring and are widely used to investigate and investigate the fluctuations and changes in snow cover globally. Modis sensor has been considered more because of its global spatial coverage with suitable spatial accuracy and frequent temporal coverage on different scales , Therefore, in the present study, snow products of this sensor were used. In this study, after collecting statistics and data on snow-related days during the statistical period (1989-2018) in three provinces of Kermanshah, Ilam and Lorestan, they were processed using Modis snow cover data in middle Zagros as well as remote sensing techniques, Finally, the snow cover changes in the study area were studied in detail. NDSI index was used in MODIS sensor products to detect snow cover. Consequently, in order to differentiate pixels and identify different phenomena, the received images were processed in GIS environment. .  Investigation of snow cover changes in different seasons using Modis sensor images shows that most of the studied area has a significant decreasing trend, especially in the elevated areas of the study area And only in the western and southwestern regions of the study area, there is no specific decreasing trend. Also, the study of snow covered days during the study period indicates a decrease in middle Zagros snow cover and these changes have been intensified in recent years, especially in snow-covered areas of the region. Also, changes in winter and snow-capped and elevated areas were more and more severe than other seasons and other regions in the study area.

Abstract

Understanding and predicting future climatic conditions and characteristics is essential because of their importance in all aspects of life. This study seeks to examine the process of modifying temperatures in the Hamedan region by using Downscaling data to predict the public circulation data and its changes. The Lars Explore Downscaling Model has been used to fine-tune the data of the General Transport Model (HADGEM2-ES) and the paired model (CMIP5) and under the three release scenarios RCP2.5, RCP4.5, and RCP8.5). Estimates of the correlation of simulated data and actual data show values of more than 0.95 for all months. P_value also showed the statistical tests of model output, acceptable values in model performance in production and simulation. As a result, the data were extracted from 2011 to 2050. Data were examined in three intervals to detect trend changes. The results show that in the optimistic scenario (RCP2.5) there is no tangible trend in the mean and minimum temperature, while in the RCP4.5 and RCP8.5 scenario there are significant trends in temperature data and accordingly increase the minimum temperature, according to the increase in the minimum temperature, according to the increase in the minimum temperature, according to the increase 1 degree in the average temperature. It shows severe climate change that, especially in the cold season, changes the type of precipitation. Also, based on the data process, the significant increase in the average annual and monthly scale temperature in all three scenarios under study will indicate the environmental crisis ahead.

Abstract

In this research, the effect of two indicators OMI and RMM of Maden Julian fluctuation on the frequency of dust storms in Abadan, Ahvaz, Bostan, Bandar Mahshahr, Dezful, Ramhormoz and Masjed Soleyman located in Khuzestan province during six months (April to September) of the statistical period (1987 - 2021) was reviewed. Pearson's correlation coefficients between dust data and indicators were investigated and its results were calculated in the form of income zoning maps and the frequency percentage of each indicator for positive and negative phases. The results of the research findings indicate that there is a direct and significant relationship between the positive and negative phases of both indicators with dust, except for Dezful station in the positive phase of OMI and the negative phase of RMM and the highest correlation coefficient for Bandar Mahshahr and Dezful station is between -0.7-20.77 is in the positive phase of the RMM index. The relationship between the Madden Julian Oscillation and dust showed that between 51 and 59 percent of dust storms occurred in the negative phase of the OMI index and 40 to 49 percent in its positive phase. In the RMM index, 56 to 63 percent of dust storms occur in its negative phase and 37 to 50 percent in its positive phase. In fact, the negative phase of the RMM index has a higher percentage of dust storms than the negative phase of the OMI index. According to the results of the Monte Carlo test, the displacement of the positive and negative phases of the RMM index significantly leads to the occurrence of dust storms for most of the stations in Khuzestan province. Tracking the paths of dust entering Khuzestan province with the HYSPLIT model shows the movement of particles from Iraq, Arabia and the eastern parts of Syria towards the studied area.

Abstract

How to design the work environment has a direct relationship with the increase or decrease of construction performance, and there are factors that if not taken into account in the design of the work environment, the administrative work will not be done properly, and in this case, it is faced with a decrease in administrative productivity. The environmental characteristics of work spaces and their impact on employees are of particular importance. On the other hand, in order to increase the productivity in the organization, we need to provide several conditions, the most important of which is the human factor, and the motivated human force to perform its duties is the most important productivity factor. The main goal of this research is to explain the optimal design model of municipal administrative spaces with an existential approach influenced by the geography of Shahrekord. Therefore, in this research, the question of what is the optimal model for designing municipal office spaces with an existential approach influenced by the geography of Shahrekord has been investigated. The research method was "descriptive-analytical" in the stage of theoretical foundations and "survey method" in the stage of expressing the findings, and the environmental variables of the office spaces, which were adapted to the indicators of existential psychology, were questioned in this questionnaire. Are after answering and completing the questionnaires by the study community, the data and information obtained from the questionnaires are analyzed in Amos and spss analytical software. The results of the research on office buildings have shown that the most important environmental parameters affecting the performance of human resources in office environments are: color, lighting, noise pollution level, visibility and scenery, indoor air quality and thermal comfort. Design, flexibility, communication, arrangement of work space and furniture, humidity, etc., which can be classified into two groups of psychological and physical components.

Abstract

 Water is a strategic and rare resource that has been severely limited in recent years due to various national and transnational variables and has severely affected the areas of security, stability, development and prosperity in countries. The high impact of water in the aforementioned areas has placed water at the center of foreign policy and hydropolitical relations of many countries, including South West Asia. In recent years, despite the issue of the water crisis and its role in the relations between Iran and Iraq in scientific, political and media circles, the dimensions of this issue remain unknown and different interpretations have been given. The current research, which is of a research nature and the required inputs were collected in a library method with the aim of obtaining a qualitative understanding of the dimensions and angles of the hydropolitical relations between Iran and Iraq, is based on the fact that, in addition to identifying the content and methodological features, the research gaps To identify the existing in this field with qualitative meta-analysis method. Using the qualitative meta-analysis method, this research has examined 34 researches conducted in the period of 2014-1402 in the form of domestic scientific-research articles, dissertations and articles in prestigious international journals. The results of the research showed that a comprehensive study has not been conducted that has investigated and analyzed the various dimensions of the hydropolitical relations between Iran and Iraq. In this regard, the lack of accurate and real data and the weakness of the theoretical-cognitive foundations of the research are among the shortcomings of the research conducted in the field of relations between the two countries.

Abstract

Drought is a natural hazard that annually causes significant economic, social, environmental, and life-threatening damage in vast areas of the Earth. The damages caused by this phenomenon are intangible but very extensive and costly, which, if necessary, remote sensing techniques can be a useful tool in monitoring drought due to high temporal accuracy, wide spectral coverage, ease of access, no need for atmospheric correction and ground referencing. In recent years, the province of Hamedan has faced many problems due to frequent droughts. Therefore, the present study focused on investigating and monitoring drought in Hamedan province using the Temperature Condition  index and its impact on the vegetation cover of the province using Advanced Very High Resolution Radiometer (AVHRR) and National Oceanic and Atmospheric Administration (NOAA) remote sensing data. First, the relevant data was extracted from the Nova star database, and finally, the spatiotemporal behavior of the vegetation cover drought index was examined on 1528 pixels in Hamedan province. The spatial resolution of the data used in this study is 4 kilometers.  First, the relevant data were extracted from the Navstar database and ultimately, the spatiotemporal behavior of the drought index and vegetation cover was examined. The results indicate that drought has significantly increased the vegetation cover of Hamedan province based on remote sensing data. Kendall's coefficients indicate the presence of decreasing trends in vegetation cover at a 95 Percent confidence level. Only in May, June, and December has there been a slight decrease in vegetation cover within the extent of drought in the province. The spatial behavior analysis of the drought index on vegetation cover showed that February, March, as well as April have experienced more severe droughts within Hamedan province.

Abstract

Understanding the daily weather types of any place location plays an important role in identifying its long-term climate. In this study, we employed the Wos classification method, along with a comprehensive climatology approach, to examine key variables such as minimum, average, and maximum temperatures, as well as cloud cover and daily precipitation. Data spanning from 1985 to 2021 were collected from 39 synoptic stations that had a good distribution in the country and had complete statistics, and weather types were identified using coding techniques. The findings revealed that the predominant temperature types in the country are predominantly hot and very hot, with sub-codes indicating generally low to moderate cloud cover and no precipitation. Moreover, the utilization of Ward's clustering method enabled us to identify three distinct climatic groups. The geographical characteristics of each place, such as location, altitude, latitude, proximity to the sea, and synoptic characteristics based on their influence, have the most important effect on the regional separation of groups in the country. The results of this research can be used to determine the weather calendar of each region during different time periods in many fields of agriculture, tourism, etc.

Abstract

 The world today is witnessing the height of geopolitical competition; An arena where only energy resources are no longer considered as the support of countries, but the corridors have become the place of power competition and every country tries to find a place for itself in the network created by these emerging corridors. In other words, the global geopolitical trend intensifies competition over maritime bottlenecks and secures access to cross-border markets. This research is a type of "theoretical foundation" research; Its method is also descriptive-analytical and it is collected in a certain way from comparative methodology with library and internet tools. It seems that in the chronopolitical alcove in the field of Iran-Iraq relations, each of the actors is trying to position their role in the international corridors, which they pursue in line with several goals; Such as Iraq's pursuit of the "FAW Corridor" initiative, and Iran, which seeks to develop the circle of economic cooperation and take a place in the emerging alliances of the East. Although it is not possible to confidently predict the future of relations between the two countries from a chronopolitical perspective, signs of less cooperation and more competition in the relations between the two countries due to various variables and reasons can be seen on the horizon. The most important indicator of possible competition includes competition in transit routes (corridors).
