Abstract
The management planning for the conservation of historical sites is a very complicated matter due to the extent and complexity of the issues of a historical site. Various international charters such as the Bora Charter, the planning models of Marta Demas, Bernard Fielden, Michel Salvian, Michael Pearson and Yuka Yukhelto have provided guidelines in this regard. Additionally, there are standard and more general models for planning a collection; among them,  strategic method and the SWOT analysis are notably important. In this research, the following basic questions are raised: What is the importance of planning the management of the conservation of historical sites and what is the appropriate way for formulating such plans? This research is considered a developmental and practical research in terms of its purpose. The method of solving the problem in the form of "hypothetical-deductive" is considered in conducting this research. The theoretical framework of the research is based on three different categories of information including: international charters, global experiences and standard planning models. In the following, information regarding the studied site (the ancient city- site of Istakhr) has been presented. Finally, using the analytical model (SWOT), the main policies for conservation planning of the site, such as determining zone and introducing them to the public and communication with the community has been introduced as the main needs of the site. The main purpose of this article is to introduce the management planning of historical sites as a management tool and a key expertise in the field of cultural heritage conservation.

Evaluation of the Impact of Nano-Absorptive Waterproofing on the Reduction of Water Absorption in Sand-Cement Mortar Used in the Historical Restoration of Persepolis

Abstract
The structure of Persepolis is subjected to various factors that cause erosion and decay due to moisture. The cement mortars used in past restorations are one of the challenges in preserving this grand stone monument. Over time, these mortars, due to higher water absorption than the stone, have exacerbated the destructive effects of moisture, causing serious but gradual and irreversible damage. Since removing these mortars and replacing the past restorative measures to improve the current situation is extremely difficult and may have damaging consequences for these valuable artifacts, this research aims to evaluate the impact of nano waterproof coatings on reducing the moisture absorption of the used cement mortars through comprehensive studies on the current state of these monuments and the restorations carried out with cement. Therefore, this research aims  to provide a suitable solution without needing to remove the cement mortar and with minimal intervention to protect these artifacts. This study employs an experimental research method and considers theoretical concepts within laboratory studies. In this process, two types of Iranian and foreign nano waterproof coatings named  Zycosil Max and FarazSil were applied on similar cement mortar samples, and their permeability and water absorption were evaluated using water absorption percentage and capillarity tests. The results showed that both waterproof coatings effectively reduced the cement mortar's water absorption. Zycosil Max, with a performance of 60.5%, and Faraz Sil, with a performance of 48.02%, significantly reduced the water absorption of the cement mortar, with  Zycosil Max showing better performance than FarazSil. However, considering that the water absorption percentage did not reach close to that of the stone samples of Persepolis and the more than tenfold difference in water absorption percentage, none of the studied materials are recommended for waterproofing the cement mortar used in the restoration of the Persepolis monument.
