Contrastive study on the elements of traditional houses in different times, is an effective method in understanding the culture and design factor, the architectural evolution, space organization, ornaments and the structure of the historical buildings and it describes that different features and distinguishing factors in traditional houses were usually closely related to the political, economy, and social issues of that region. Synchronized with historical dynasties, traditional houses are thus, easily distinguishable regarding their architectures and the manner of architectural pattern can be followed regarding the historical evolution. As Isfahan was the capital of Iran in Safavid time, building magnificent palace-like houses were the trend; in Qajar dynasty as well architecture had its own unique elements. The present study enjoyed the mixed methods of descriptive and analytical methods as well as case study. The problem was examined based on observation, field studies, and documentation; the results then were compared and contrasted. The architectural design of these houses are introverted (mainly) as well as extroverted (in jolfa). The main front of the houses are in southern part and having porch, straight sky line, rectangular garden, rectangular rooms, sometimes octagonal houses, abundant ornamentations in central halls, using natural colors, easier use of bricks as the main material are some features of these houses. The present study aims to analyze and evaluate how the privacy of entrances in both Safavid and Qajar houses as one of the most significant elements of architectural times formed. 

Crises have always caused many, and sometimes irreparable, damages and injuries to human nations having had adverse impacts on indices of society, economy and environment. Therefore analysis and optimum management of these crises are the priorities in the states around the world. Access to valid and up-to-date information plays the pivotal role in proper and timely programming and performance on managers’ and responsible organizations’ side in various phases of the crisis management cycle. While more than 80% of the required information in crises actually have a local and geographical nature, utilizing the modern technology of GIS with special capabilities in modeling, combining and analyzing the data can be effective and impasse-breaking while analyzing vast layers of information in both phases of prediction and strike of crises. A good knowledge of the crisis-causing factors before their strike or prediction of the essential arrangements to prevent or reduce their affects or aftermaths to the least is one of the base procedures in the management of unexpected events. In this direction, precision in properly locating the installations and passages of the pipes and canals would be immensely important; bearing in mind the key role of continuation of serving essential arteries; particularly water and sewage installations, in controlling and preventing the expansion of crises, and preserving public health and hygiene on the one hand, and the significant expenses of construction or reconstruction of these systems on the other. Thus, through this study, we have discussed how to exploit the creation and production procedures in purposefully locating water and sewage installations and also their other usages in designing, management, programming and development of these installations, in addition to introducing the geographical information systems and clarifications of the creation and production procedures. The location of urban water and sewage facilities is very effective in increasing the resilience of natural disasters through the use of the geographical information system.

In urban planning, access to public spaces provides social relations for citizens. The goal of this paper is to evaluate the elderly's requirements in public spaces (case study of Sheet Bazaar, Zanjan, Iran) in order to recognize and classify their strengths and weaknesses and present more appropriate and effective strategies for their improvement. In this research, the related literature on old age and requirements of the elderly in public open spaces was reviewed and the factors affecting their use of physical places were determined at the first stage of the study. After reviewing the literature, some observations on the elderly were made and questionnaires were given to 80 users with the age of over 65 years old to serve the purpose of this study. The results of the questionnaires indicate that the frequent problems of the elderly in public open spaces were identified as follows: pollution (24.8%), pavements and roads (24.6%), traffic (14.4%), safety (12.2%), insufficiency of maintenance and management (9.6%), and socio-cultural problems (5.3%). In addition, the result of the observations in the main research area shows that the design properties had the highest and maintenance-management services had the lowest success percentages. In the end, some solutions were presented for designing new public open spaces and developing the existing spaces.

Park design in Iran has followed the traditional European style since the Qajar dynasty. The familiarity of Iranians with the spirit of Persian gardens and the low quality of the newest parks is such that users prefer ancient geometrical Persian gardens. Today, those responsible for the design of urban green spaces lacking examples differing from the traditional and thus they are in need of an adequate set of guidelines for how to design for present conditions, users, and their needs. This research focuses on the relationship between park design components and users’ psychological restoration regarding their preferences and perceptions to increase the quality of parks, diminish vandalism, and increase user agency. Psychological restoration is the likeliness that people will be able to rest and recover their ability to focus. A random sample of 100 Tehranian residents was taken by presenting them with images depicting 6 urban parks from around their city. The results were analyzed by grouping into categories: 1-similar activities and 2-by counting and categorizing the individual descriptions of components (frequency of words) contributing to restoration likelihood. Findings showed that the categories mentioned most frequently for high levels of restoration were natural categories including trees, shrubs, grasses, flowers, and water. Findings with low levels of restoration and recovery consisted of negative contextual conditions and the absence of nature such as high rise buildings around the parks, lack of trees, and crowds of people. The activities imagined more frequently were playing and other physical activities, social activities, and relaxation.

The expansion and growth of cities is a remarkable phenomenon in urban planning literature, so that unpredictable developments have become more evident in recent decades, especially in cities that have undergone changes in their physical structure following the promotion of their political role. The present paper seeks to identify the factors driving growth in the developed areas of Ardebil city and extract basic factors and variables by investigating development of Ardebil. In this study, 27 variables have been tested in 920 expansion blocks during the years 1996 to 2011 using GIS and factor analysis. Four main groups including congestion factor, external factor, access factor and facilities are identified as driving forces of growth. The final combination of four factors in the Arc GIS environment show that the north, east and south east blocks of Ardebil had a higher score than the other blocks; in other words, these factors have the most effect on the growth of these areas. In addition, the Southwest blocks with the lowest score of between 0 and 2 have had the least impact from among the factors mentioned.
