Purpose- Planning for optimum distribution of physical services and furniture in order to improve people’s welfare is one of the major purposes for rural planners. Rural furniture is the main purpose of developing rural settlements to decrease environmental side effects. The quality of human environments in villages highly depends on the quality of infrastructures of physical welfare including rural furniture. Rural furnitur e not only improves the quality of villages, but also keeps them consistent and permanent. The present study involves analyzing rural furniture and their effects on the environmental quality of rural settlements in Zoeram Dehestan, Shirvan. Design/methodology/approach- In this research we used an analytical-descriptive approach and data was gathered through library information and field study. Statistical population involves all rural families of Zoeram that equals to 258 families randomly selected through Cochran Formula with error level of 0.06. We used a questionnaire that its reliability was confirmed by a specific academic panel and its validity was calculated through α-Chronback coefficient. We also used SPSS software to analyze the data. Findings - The results obtained from Chi Square Test show that among all dimensions, aesthetic and visual beauty factors with mean of 2.70 and among all rural furniture, infrastructural furniture with mean of 3.17 are the most effective factors in increasing the quality of physical environment. Also, results from Spearman Correlation and Simple Linear Regression Models show that there is a strong, direct, and meaningful relationship (Sig: 0.000) between rural furniture and the quality of physical environment. In the end, using Gray Correlation Analysis and Vikor Method, we get the results that in these villages with different qualities in rural furniture, environmental quality is not the same level and according to Spearman Correlation there is a strong, meaningful relationship between the quality of rural furniture and the quality of environment. Practical implications- Today it is vital to consider and improve the quality of rural settlements, since it has been a major concern of local administrators and rural planners. In this respect, analyzing and measuring the level of available rural accommodations can be a helpful tool to understand and to show differences and inequalities in villages in order to provide better life quality in rural areas and be able to obtain more successful goals and objectives in establishing rural stable development and constant population growth. Originality/value- No direct research and study considering changes in the quality of rural settlements due to establishing rural accommodations have been done so far. Therefore, it is worth performing a thorough, comprehensive research and study regarding both rural accommodations and quality of environment to show the differences and innovations in this field.

Sustainability and resiliency analysis of cities is not completed without considering the whole system of interacting sectors. The purpose of this study is to introduce an algorithm for assessment of overall seismic resiliency increase of urban areas due to the reduction of Intra- and Interdependencies between different sectors and retrofitting infrastructures. The proposed method is versatile, and different dimensions of resiliency, i.e., social, economic, technical, physical, institutional, and security dimensions of resiliency are considered in the study. In this research, the technical dimension, i.e., the functionality of water and power networks are modeled as an example, and some solutions to increase overall resiliency of an urban district against earthquake is investigated. The algorithm is based on the inoperability input-output model, and the interaction between water and power sectors in a metropolitan district is surveyed. Based on the results of a number of Monte Carlo simulations of different dependency scenarios, it is quantitatively shown that the decrease in interdependency has a direct and great effect on the increase in serviceability and overall resiliency indices, but the pattern of this effect is different between various earthquake scenarios. It is concluded that the reduction of interdependency has an increasing effect on the overall resiliency index. Thus, an optimum value for interdependency reduction can be obtained to increase resiliency index using the Pareto principle, and the influence of reducing of interdependency on increasing the resiliency of a region as a whole is investigated. The proposed model may be used in system analysis for other dependent sectors and for different disasters and can also be considered as a helpful measure for decision-makers in sustainability and resiliency enhancement studies.

Cities are considered the most important social, economic, political and cultural activities. The study of the growth of urbanization shows that the growth of the urban population is increasing rapidly and the cities are facing a high rate of population growth and have not yet been able to control the problems caused by this growth. Today, the phenomenon of immigration is considered as one of the most important and complex problems of third world countries. It is obvious that our country is not far from these issues as the investigation of various studies shows; The issue of migration, especially migration from the village to the city and sustainable rural development, has been widely studied, but the immigration acceptability of villages and its relationship with sustainability issues, especially social sustainability, has been less of a focus of researchers. Regarding the city of Mahabad, it should be said that the development of this city in the past years was mostly due to the migration of villagers to the city and also the natural growth of the population. The issue of this article is the sustainable economic and social development of Mahabad city and its impact on the migration of subordinate villagers.
