  The major style of urbanization in Isfahan has been always conventionally based and focused on pedestrianism. This city whose frame and structure is organized and nearly completed in the Seljuk and Safavid eras, still (particularly in the old areas) is under a system based upon evaluation of the qualitative properties of districts and maximum connection between people  and environment .Though from early  20^th century and the start of modern transformations in architecture and urbanization in Iran, building new and modern districts with central focus being on maximum usage of land to build infrastructure and paths for passing cars, the pedestrians are less valued .Regarding this point that city development and description of new necessities by humans has inevitably new activities and utilizations in definition of districts, by comparing the new and old districts of Isfahan we can significantly come to the conclusion that how each one`s frame work properties can satisfy today human beings' requirements and interactions and what the strategies for their adjustment and promotion are .This article compares the capacity of pedestrianism and social interactions between an old and a new-fashioned district in Isfahan in order to discuss the strengths and foibles of them. The discussed titles are: aim of research and the way of that, reviewing the supplies about new urbanization and walkability, checking pedestrianism in two districts of Isfahan, and the results of the research .The final parts discuss the results of the review and physical position of two intended districts. Finally, the implications will be presented as guidance principles to design new-fashioned neighborhoods in order to improve the quality of neighborhood and social interactions due to the walkability.

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.

 Space perception is the firs t s tep towards recognizing and communicating with the environment. Despite similar perception sys tems in human beings, the perception of surroundings is different from person to person. Therefore, different perceptions of similar objective spaces can result from several factors, and only one influential factor cannot determine the perceived subject. This s tudy seeks to identify cognitive aspects of different areas of the elderly perception in architecture and determine the cognitive characteris tics of independent elderly residents in Shahrak-e-Gharb of Tehran to obtain primary data and their perceptual, cognitive characteris tics using cognitive maps. This is a theoretical-applied s tudy with a qualitative-quantitative method. The library method was used for data collection, field observation to measure the s tatus quo, and interview and cognitive maps technique to collect research data. The sample size of 38 persons was calculated using the Cochran formula. According to the findings, the average perceived cognitive paths of the men group were higher than that of women, and the average perceived cognitive places of the women group were higher than that of men. Aging and length of residence do not affect the number of perceived elements.  As aging occurs, the number of perceived places decreases, and the number of perceived paths increases. Mos t recognized spaces in cognitive maps represent a place for people's memories. So, cognitive spaces should be improved before the cognitive abilities of the elderly decline.
