Introduction: Today, the method of distribution, provision and realization of urban services is one of the important necessities of urban life and urban development plans. However, the use of traditional methods of providing land for urban services has led to the fact that many lands allocated for public services have not been realized and have created problems for citizens and city managers, and therefore some areas of cities lack the necessary services to Biology is appropriate. Therefore, this issue leaves no choice but to resort to new methods in front of planners and city managers; these include the development of a right to development, which is based on respect for property rights. This study, using the fields and theoretical foundations of the subject, studies the feasibility of using the method of transferring the right to development to increase the feasibility of urban services in Karaj (areas No.1 and No.2 of the city) and seeks to answer the question that the requirements and What are the conditions for using this approach and which parts of districts No.1 and No.2 of Karaj are suitable for this model.
Methodology: To answer these questions, A Analytical Network Process is used to prioritize the indicators and ArcGIS software is used for spatial analysis. According to the pattern of transfer of development rights, the neighborhoods located in districts No.1 and No.2 of Karaj city were divided into areas for receiving and transferring development rights.
Results: The results showed that in the receiving areas, occurrence in the high compression zone in the comprehensive plan with a weight of 0.22 is in the first place, high land price with a weight of 0.16 is in the second place, high price in the residential unit with a weight of 0.15 is in the third place. In the areas of sending the parameter, the lack of government funding for land ownership with a weight of 0.34 is in the first priority, the high service levels proposed by urban development projects with a weight of 0.24 are also in the second priority. Azimiyeh 4 from District 1 has a very large capacity to receive development fees and the faculties of the faculty and Shah Abbasi and Moradab public areas have a very large capacity to send development fees.
Conclusion: Finally considering this method faces legal, financial and managerial challenges, Suggested to solve these challenges, Providing mechanisms and requirements such as prediction in urban development plans, Establishment the Office of the Transfer of Development Rights in the municipalities, Provide incentive packages By municipalities in order to creating motivate participation, And review the laws and regulations related to property rights in order to increase the efficiency of the method of transferring the right to development.

Introduction:
This research aims to answer the fundamental question of how environmental factors are perceived by COVID-19 patients in hospitals and through what mechanisms. In other words, from the perspective of patients hospitalized in the country's hospitals, what environmental factors have the greatest impact on their perception and therefore, the improvement of their physical immune system in the face of the coronavirus? By evaluating these factors, strategies can be developed to improve the quality of environmental and physical factors in hospitalization wards and potentially enhance the patient's condition.
Methodology:
The present study is a descriptive survey type in terms of its objective, applicability, and execution method. The statistical population of the research consisted of private hospitals in the city of Karaj, including five hospitals which had 138 recovered patients from the COVID-19 ward in the fourth peak of the coronavirus pandemic. Using the cluster random sampling method and the Cochran's formula, 102 individuals were selected as the sample. The reason for using quantitative methods instead of qualitative ones was the better generalizability of the research results and the research objective, which was to evaluate the effective environmental and physical factors on the perception of COVID-19 patients from the perspective of those who had firsthand experience in the hospitalization ward. The data collection tool was a researcher-made questionnaire with 6 dimensions, which was validated and its reliability was confirmed by content validity and Cronbach's alpha coefficient. Data analysis was carried out using SPSS software version25 and the model was fitted using Smartpls software version 2.
Results:
The research findings showed that environmental and physical factors that affect the perception of COVID-19 patients can be classified into 6 categories: "facilities and equipment, visual attractions, thermal quality, air and lighting quality, sound quality, comfort, and accessibility".
According to the findings, the level of impact of sound quality factors had the highest potential with a coefficient of 84.2% in explaining the changes in patients' perception of environmental and physical factors. Thermal quality with a coefficient of 83.6% indicated that the cooling and heating temperatures of the room and corridor were in a desirable state. The level of comfort and ease of accessibility had a potential of 60.7%. The facilities and hospital room environment factor had a coefficient of 31.4%, and visual attractions had the least potential in explaining the variance of patients' perception of environmental and physical factors with a potential of 14.6%.
Conclusion:
Based on the results of the present study, with environmental and physical interventions and attention to these factors in hospital design, steps can be taken towards changing and improving these variables and providing a faster improvement for these patients, as well as improving mental imagery content by increasing the readability and clarity of the environment through changes in the presentation of spaces and defining the boundaries and scope of each activity. One of the limitations of this study was the difficult access to recovering COVID-19 patients. The results obtained in this study can be a prelude to the definition and design of future research.
