In this study, we explore how urban places and associated community affect one other as well as the quality of life of rural immigrants. The purpose of this study is to provide more accurate insight into the spatial and social factors affecting the quality of life of rural-urban migrants. Migration is closely linked to people's living conditions. Specifically, the feelings one has about the quality of their place and the society in which they live impacts decisions to stay or move from one place to another. If deciding to move, migration affects the quality of life through the migrants' sense of place and the new community they are relocating to. Our study was conducted in Hamedan, Iran-a place that experiences the migration of many different ethnicities given its central location in Hamadan province and the quality of life conditions in surrounding geographical locations. We surveyed 2735 citizens who had migrated to the city in the last 2 to 5 years. Our results indicate that place attachment and social capital, as variables that represent rural migrants' sense of place and urban community, are both related to the quality of life of migrants. Furthermore, social capital moderates place attachment and has a significant impact on subjective quality of life among rural-urban migrants. We suggest that high levels of social capital must be present to ensure a satisfactory subjective quality of life among rural-urban migrants.

One of the major problems human beings are confronted with in urban setting is the removal of urban waste. This problem has persuaded the urban authorities to use various tools such as Geographic Information System (GIS) to locate landfills. To do that, Sloan Digital Sky Survey (SDSS) has been used in which or multi-criteria decision making (MCDM) methods and GIS are combined. The selection of the burial place and landfill has great importance and different criteria must be considered. SDSS, using MCDM is able to investigate locating landfill using various criteria simultaneously and it determines its importance. This research aims at presenting suitable solution through using computer and GIS related to solid urban waste and their locating in Hamadan based on standard criteria. A comprehensive model based on GIS, to get the suitable burial place and landfill can help to save time and cost. The model of locating burial place of urban solid waste has been presented.
