Abstract
Generally speaking the existence of metropolises, alongwith the high various business districts have led to high valume of travels to these centers.The density and separation of these centers brings about the increase and the decrease of the vehicles. The adoption of location determination strategies and that of the comunicational centers and the city activities has made the cities continue the developement process while cosidering the fairly service destribution and the spatial equalities.The goal of this research is the recognition and determination of the city spatial organization working centers and activity model and the relation of service functioning with one another so that the mono central and poly central cities can have a important effect on the destribution system and service centers and the vast changes of the citizens .The analysis method is a kind of quantity and quality one. In the quality part of that the descriptive statistics ( the geometrical presentation , graphical disparation, the centralism measures) and the Hansen Model. In the areas of planning, a great difference is seen in the levels of land uses so that the land use of higher educations in the western metropolitan city of Mashhad area is 84 percent while that of the eastern area is 3 percent. It is the same about the equipped medicinal, commercial and green space areas.Only in the areas of managerial levels there is a relative balance. Finaly the city is devided by three areas throughwhich while considering the employment , the developement potential and distance , the land use determining rate was found out.

Abstract
Today, the number of elderly people is increasing due to various factors such as changing life expectancy and population distribution. On the other hand, this period of life requires special needs such as care and health to other external and environmental factors. The social phenomenon of the city is not separate from this population group, ie the elderly, and urban planners using environmental theories can take steps to improve the use of the elderly in the city and its public spaces. In this regard, the purpose of this study is to explain the components of the elderly-friendly city with an environmental psychology approach in the eight cities of Shiraz. After identifying the characteristics to obtain the required information using a questionnaire tool that Cochran's method was used to determine the sample and GIS data were generated using Moran analysis of the desired layers and then using hierarchical analysis and Hot spot analysis of overlapping criteria was performed using fuzzy functions and urban spaces needed by the elderly were identified. Then, by confirming the hypotheses in this field that attention to social components along with components of spatial structure can be appropriate to improve the urban environment, suggestions in this area from attention to access and public transportation to creating an environment Elderly entertainment was provided.

Abstract
Reconstructing paleoclimate, particularly environmental temperature, plays a crucial role in understanding both current and future climate patterns. The aim of this research is to investigate the climatic conditions and estimate the ambient temperature during the Holocene period based on two sediment cores extracted from the Jazmurian Basin. Paleotemperature reconstruction was conducted using several methods, including the calculation of the standardized coefficient of variation of oxygen-18 and carbon-13 isotopes. For this purpose, the isotopic analysis of oxygen-18/oxygen-16 and carbon-13 was performed. In Jazmurian core 1, the initial temperature was estimated at 46°C. A decreasing trend of approximately 10°C was observed down to a depth of 175 cm, distributed across eight stratigraphic levels. At 175 cm, the temperature shows an increasing trend, followed by a decline at the subsequent level, and then a return to an increasing and stable trend in the next two levels. In Jazmurian core 2, the initial temperature was approximately 50°C. A sharp decrease in temperature is observed between depths of 80 to 125 cm. Subsequently, there is a slight increase of about 1°C, which remains relatively stable until a depth of 170 cm. Beyond this point, the temperature decreases again in the final two layers. The concentration of carbon-13 in core 1 ranges from 0 to 25.6, while in core 2 it varies between 25.9 and 27.1. In core 1, six carbon -13 isotope samples show a value of zero, indicating an absence of carbon-13 in those sediment layers. In contrast, core 2 displays a narrower range of variation in carbon-13 values. The isotopic and temperature variations observed in these sediment cores reflect different climatic phases during the Holocene in the Jazmurian region. Such climatic changes are often linked to cultural shifts, and the decline of ancient civilizations has frequently coincided with environmental transformations. The findings of this research may be of significant value to archaeology researchers, particularly those studying ancient Iranian civilizations.
