The present research aims to study youth satisfaction from public urban environments and to identify the factors effective on youth satisfaction. The main question of the research is: What factors can affect youth satisfaction from public urban environments? This research has been performed by analytical-descriptive method. The statistical population consists of all youngsters in the age group of 13-17 years old in the city of Tehran, which was selected based on systematic random sampling method with a size of 333 persons. Based on the research findings, there is a significant relationship between the four variables of research, that is, "Service Access," "Social Security," "Dwelling Record," and the secondary variable of "Physical Specifications of Dwelling Place" with dependent variable of "Youth Satisfaction" ( p < 0.01). Only the variable of "Socio-Economic Origin" did not have any significant relationship, and was rejected. Youth satisfaction from public environment in the area under study was estimated in a lower threshold (5 > 2.82 > 1 with theoretical equal to 3). Moreover, the variable of "Service Access" with causative effect of 0.396 has the highest correlation with youth satisfaction from the neighborhood.KEYWORDS public urban environment, quality of life, satisfaction, youth and child friendly city

In the present age, environmental sustainability has been severely challenged because of the human constructions and changes in the ecological landscape of cities so that the issue of the compatibility of urban development with these changes has become especially important. Changes in morphology, structure, form and geometry of the cities, which are themselves caused by changes in the form of urban complexes and geometry of buildings, have a profound effect on the micro-climate and sustainability of urban environments by the efficient adjustments. To assess environmental sustainability or unsustainability in urban neighborhoods, thermal comfort is considered as a good indicator. The assessment of this qualitative concept requires the use of quantitative indicators and assessment tools that can be spatially presented to urban planners and designers to help them in urban development plans. The PMV/PPD model uses heat-balance equations and empirical studies to calculate the ‘predicted mean vote’ and ‘predicted percentage of dissatisfied’, which are somehow derived from the parameters that affect thermal comfort. The innovation of the present study compared to the background of the researches is the evaluation of urban building design policies in thermal comfort, which fills the gap between the evaluations of the level and scale of architecture and urban planning in previous researches. An applied and descriptive-analytical research method has been used in the present study. Firstly, data needed to evaluate the main purpose of the research in the selected site located in the Gheytariyeh neighborhood of Tehran were collected. They are then simulated and analyzed. The results indicate that the difference in the geometry of the buildings and the city blocks can make a difference in the heating comfort of the different city neighborhoods and residents. The recent study has proven that the difference in the city blocks (3- and 4-dimensional and square shapes) can affect the comfort and temperature factors. Spatial simulations conducted in the present study by ENVI-met software show that compared to other indices studied, the PMV and PPD indices have the least distance from the ideal thermal comfort conditions in the design of trilateral high-rise buildings and have the greatest distance from them in the design of rectangular building blocks. It is worth noting that the adoption of policies and regulations related to the design and architecture of urban neighborhoods by the implementation of urban development policies is one of the measures required when the urban development plans are drafted and approved. The simulations model indicates that the minimum and maximum values of PPD index have been respectively equal to 51.06% and 99.96% for the option 1 (three-sided block), 56.09% and 98.26% for the option 2(four-sided block), 57.32% and 98.19% for the option 3(empty middle block) and 58.76% and 98.05% for the option 4 (rectangular block). The present paper has tried to explain the requirements of it.

Short AbstractGiven the industrialization of societies and the growing population of the elderly and the emergence of many diseases which is caused by the unfavorable condition of their lives, the basis for the health of the elderly should be established by promoting the quality of life. The purpose of this research is to provide factors and attributes that affect the index of hope and quality of life and to achieve a desirable environment for the elderly. In order to advance the research, a descriptive-analytical method has been used in a survey approach that includes library and field studies. Also, SPSS software and one-sample t-test were used as a tool for data analysis.Considering the results, ease of access to spaces, security, dynamism and attractiveness, unity and integrity, freedom, comfort, communication with nature, social participation, educational and cultural activities, and place belonging to raising the level of life expectancy in the elderly have a significant effect. According to the results of the Friedman Ranking test, the four factors that have the greatest impact on improving the quality and life expectancy of the elderly are: the relationship between the elderly and nature, social participation, comfort, participation in the educational, and cultural activities. ‫سالمندان‬ ‫در‬ ‫زندگی‬ ‫به‬ ‫امید‬ ‫ارتقاء‬ ‫بر‬ ‫مؤثر‬ ‫عوامل‬ ‫تحلیل‬Analysis of Factors Affecting the Growth of Life Expectancy ... 297 Extended AbstractIntroduction: Given the industrialization of societies and its economic, cultural, and moral consequences,the growing population of the elderly,the emergence of many diseases, and problems of aging which is caused by the unfavorable condition of their lives, the basis for the health of the elderly should be established by promoting the quality of life and it should also be stepped up to achieve dynamic aging. The purpose of this research is to provide factors and attributes that affect the index of hope and quality of life and achieve a desirable and satisfactory environment for the elderly. They have been effective in restoring their physical and psychological well-being, providing them with refreshment and higher level of life expectancy and ultimately improving the quality of life of the elderly. Therefore, the issue of paying attention to elderly people living in nursing homes can have a positive effect on highlighting the role and importance of the elderly and improving their quality of life in the society. Method:In order to carry out the research and achieve its goal, a descriptive-analytical method has been used in a survey approach that includes library and field studies. The library method with tables and statistics is used to reach the psychology and sociology of the elderly and the situation of the elderly in different societies and the principles of design and architecture criteria for the elderly. Field studies, including interviews with the elderly, experts in the fields related to the issues of the elderly, specialists and others, have been used as a supplementar...
