Since ancient times, the issue of registration in various areas of life has always been with mankind. Registration is a cultural issue and is considered a reflection of various cultural areas of mankind. Every work left by man in the past, whether it was in the form of an image or a line, reflects and illuminates a world of material and spiritual information and knowledge like an honest mirror without any pretense or imperfection. The characteristic of all registered subjects throughout history has been their "value and importance" for greater permanence and transmission to the periods ahead of them, and this transfer of value to future generations continues today. In the field of cultural heritage and the protection of historical buildings and cities, the issue of registration is very valuable and important. A noteworthy point in this field is the relevance of re-registration of values. Because we re-register the material or spiritual work registered during the creation period so that it is protected and subject to legal protection and public attention, and most importantly, in the process of sustainable development and handed down to future generations. This article, which is the result of objective observations and library and document studies, describes in an analytical-descriptive manner the nature and importance of registration and how the relationship between registration and value, conservation, and sustainable development is defined. Another goal of this article is to examine the role of registration in the protection of cultural heritage values and its place in the sustainable development process.

The erosion of adobe heritage under the influence of natural factors, especially rainfall and humidity, is one of the most important challenges in the conservation of this heritage today. Alongside traditional options for the protection of adobe heritage, such as the use of straw plaster, in recent years, various chemical products have been marketed for the protection of building materials and components, especially against the threat of moisture, and consequently, serious tendencies have been expressed in the field of evaluating these materials in the field of conservation and restoration. Therefore, the scientific evaluation of the properties of these materials seems necessary for their judicious use. Since many of the chemical materials available in the market are mainly designed for the protection of stone and brick, it seemed necessary to conduct this study in order to protect adobe materials and optimize the penetration of these materials into the adobe texture. In this research, considering the need to increase the resistance of adobes against moisture, the hydrophobic properties of four different commercial products with the names of Stain Repellent AKEMI, SRP130, PTS+ and Long Life, were evaluated and compared with each other on the structure
of adobes. The results of the research showed that although all the commercial materials studied provide the possibility of significantly increasing the resistance of adobe against moisture, the Long-Life material has a higher ability to penetrate and hydrophobize adobes compared to other chemical products. This issue can significantly increase the surface resistance of the adobe against both long-term contact with moisture and against mechanical erosion factors. The results of this research can be used as a basis for future studies in the direction of localizing chemical materials for the protection of adobe works and optimizing their application in the conservation and restoration of adobe historical buildings.

Valuable cultural heritage is always exposed to the invasion of biological agents and the resulting destruction, especially when the physical and chemical conditions of the work and its surrounding environment are compatible with the characteristics of an organism or a microorganism. Therefore, preventing the occurrence of such conditions and limiting the invasion of biological agents should be among the main and primary goals of every center. Over the years, various methods such as the use of disinfectants have been used to control biological agents in various historical and cultural collections. With the passage of time and increasing awareness of the harmful effects of these substances on the treated works, the environment and the users, nowadays the use of non-toxic alternative methods is more recommended. Experience has shown that the method that causes the least damage to collections and employees is preventive methods and regular control, which is possible through monitoring and managing the environment. Integrated pest management with the ultimate goal of removing harmful biological agents from a place is one of the long-term preventives and non-toxic methods of controlling biological agents that is used in many museums, archives, and libraries. In this article, along with a brief overview of biological deterioration and its preventive and control strategies, microbiological monitoring of the air inside 4 storerooms in the world heritage complex of Golestan Palace Museum including: the anthropological clothing, the manuscripts, the carpets, and the Painting storerooms was carried out. For this purpose, air sampling was done by sedimentation method and isolated microbial colonies on the culture media were investigated and identified. The results of the microbiological monitoring of the air inside the storerooms in this study showed that except for the carpet storeroom, other studied storerooms, including the anthropological clothing, the manuscript and the painting storerooms, are acceptable in terms of the number of microorganisms in the air.
