Rapid urbanization and lack of urban readiness for accepting emerging social conditions have led to the formation of low-quality of urban environments in many developing countries. This issue has directly affected the quality of life of citizens. The purpose of this paper is to investigate the variables affecting citizens' satisfaction about the quality of urban environment in Ardebil’ s District 4. This research is an applied and developmental purposely and descriptive-analytical methodically. A sample of 382 people has been questioned. For data analysis, one-sample T-test and independent T-test, multiple regression analysis (Enter), Variance or F test, and Scheffe's test to examine the difference between several groups has been used. The results of this research show that residents' satisfaction from the quality of urban environment is at a low level. So that the level of satisfaction with the quality of the urban environment is lower than the theoretical. Independent T-test and Variance test showed that type of occupation, education level and settlement duration, affect the level of citizen satisfaction from urban environment quality. Other personal characteristics do not affect the quality of the urban environment (age and gender) in citizen satisfaction. The residential environment variables have a far greater proportion compared to other variables in predicting the dependent variable.

Evaluating trend of land cover changes for accessing to correct and timely information from the various terrestrial phenomenon is the basis of different planning. Remote sensing technology is known as suitable tool for studying of changes of terrestrial phenomenon. The purpose of this study is the investigation of land cover changes trend in Damghan. The Landsat TM satellite images for 1986 and 2011 and the lands cover digital map are used. Using of Land cover maps, 6 units (forest, pasture, agriculture, barren, salt-marsh and earth-city) have been detected in this region. After doing the geometric and radiometric correction on satellite images, changes of units have detected by using of Tessledcap transformation, supervised classification via maximum likelihood method and processing after classification for 25 years. For estimating of accuracy, obtained Overall accuracy and Kappa coefficient (0/9) are acceptable in each image. The results shows that extent of the earth-city, agriculture and barren lands have increased and the extent of the forest, pastures and salt-marsh have decreased during these years. The highest increase is in the earth-city unit about 9/59 percent and the highest reduction is in the forest cover about 16/48 percent. In with due attention to obtained results, the most of changes related to decreasing of forest by converting of forest to pasture and increasing of earth-city by converting of pasture to earth-city.

City as a text is a complex network of cultural codes which provide reading of city for people. By this explanation, this text can investigate and analyze through semiotics approach. Exploring shows that the trends which happened after capitalism and modernism, have had influence on this text and decontextualized from its textual layers, so changing in role of signs happened (sign is an analytical media for analyzing the text). In other words, signs in modern and capitalized city, is not a cultural sign and readable ones for observers. There are only functional signs or maybe symbolic ones. Baudrillard named this changing as economic-political theory of signs. So signs decade to their lowest functions and therefore the lowest level of meaning perceived, which lead to suspending and plurality of meaning for observers. Urbanscape is the first scene which human perceived and observed when faced with the city. Therefore, urbanscape chose for analysis in this article. Defining the influential factors, which decontextualize from urbanscape, is the main goal of this research. For achieving the goal, first investigating the concepts and defining the theoretical framework done, then major urbanscape of Karaj explored as the case study. For this goal, new constructions, which decontextualize from the text (urbanscape), are considered. This analysis based on semiotic approach and economic-political theory of sign. Results shows that emphasis on functional and symbolic dimension of signs and economic and political trends lead to constructions with no compatibility to textual layers of urbanscape which make problems in readability and perception of it.

Planning and management for rural sustainable development is one of the fundamental tools for access to spatial justice. Spatial equality in rural development led to efficient use of resources, social welfare and economic growth. Accordingly, analyzing spatial changes of sustainability level and rank in rural area required for decision making and rural planning and can reduce unsustainability as well as provide efficient policy and strategy for promotion of quality of life. In this regard, the main goal of this paper is investigating how we can link different indicators of sustainable rural development and introducing an appropriate ranking model for sustainability in the rural territory of Sarband district in the Shazand County, Markazi province. Research method is descriptive and analytical and we used questionnaires, expert’ s opinion, DEMATEL and ANP model to calculate the weight of indices and models for integrating ELECTERE 3. The results shows that, Kosar, Lvzdrlya and Qayydan villages have the highest levels in terms of sustainability and Vazmstan Olya village has the lowest level of sustainability.

This article attempts to review and explicate Planning ethics concept, largely as articulated by exponents of the practical ethics, in terms of the planning theory. The paper can be read in a sequence of a larger argument about planning ethics and it makes more urgent the existing critiques of planning theories without ethical direction. We develop – based on thematic analysis method-how professional ethics codes in planning produce important issues that must be considered. So at the very core of the article is an attempt to recompose of the ethical view about planning tactics in the decision-making process, to break out from idealism of conventional planning theory to make space for the insights of realistic thinking about planner behavior. The article argues therefore that the idea of problem-oriented ethics in planning can go realized.

Over the last few decades, social capital has been recognized as one of the most important factors in achieving sustainable development. In this regards, several studies has been done on the assessment of social capital as well as its impact on social sustainability of urban neighborhood. The mentioned issue has always emphasized in Tehran municipality by formal and informal organizations. In this regard, this paper based on descriptive-analytical method aimed to survey and measuring social capital in Evin neighborhood as well as its relationship with social sustainability. In this paper, non-probability sampling is used in both experts and resident’ s levels and data collection has been through field and documentary studies. To analyze data, AHP model in the Expert Choice software, one-sample T-test, Pearson correlation and regression in the SPSS software are used. The result shows that the level of social sustainability in Evin neighborhood is medium and also the positive correlation is significant between social sustainability and sustainability.
