Abstract
Among the Turkmen, shamanism is the ape tic method based on ancient ethnic beliefs, which is still a common notion that has gradually been merged with religious beliefs and symbols of shamanism with religious fusion have continued to this day. The main purpose of this study is to investigate the basic concepts of symbols that originated from the beliefs, rituals and rituals of the Turkmen tribes of their primitive religions. Information the findings were collected by field method and direct observation using the main library resources. The main findings of the research are based on the symbols and signs of shamanism, as the ancient beliefs and rituals of the Turkmen tribes. Fairy readers are considered to be the main and last survivors of shamans among the Turkmen tribes each of the fairy readers has an army of goblins at their disposal and command this study tries to answer basic questions such as key elements in shamanism, the place of shamanism in the Turkmen belief system and the historical – cultural origins of shamanism in Turkmen culture.

Introduction
Undoubtedly, among contemporary thinkers in the field of symbolic anthropology, Clifford Greets is one of the most famous anthropologists in the field, due to his particular approach to culture and his new approach to the humanities and social sciences. Geertz’s position beyond anthropological boundaries as an interdisciplinary figure in the social sciences. His theoretical approach to anthropology is broadly symbolic and combines philosophical, anthropological, and even linguistic theories.
Analysis of religious behaviors and practices is one of the central issues in the field of anthropology of religion. How behaviors and actions can be studied objectively and realistically and as a phenomenon is one of the serious issues in the anthropology of religion. This issue led to extensive developments in the theorizing of the humanities and social sciences in relation to cultural and religious phenomena in the second half of the twentieth century AD.
In general, in the 60s and 70s of the twentieth century, symbolic and interpretive anthropology with its own approach to culture, was confronted with material tendencies, such as materialism or cultural positivism.
In this view, cultural phenomena move from the belief that culture is a set of meanings that are understood and received trough symbols and signs, and to understand it, one must first go to the analysis of these symbols.
It is Clifford Geertz who has emphasized such as model as a method in anthropology. He has been able to bring about extensive changes in the definition of culture with an interpretive methodological approach.
Based on observation and return to the field of social sciences, he created a new model of interpretation and semiotics in the anthropology of religion. (fakoh. 1386: 108).

Shamans Treatment Method 
Shaman and shamanism are among the most important topics in the anthropology of religion. Shamanism is not a new subject, but every research on religion is devoted to it. What distinguishes the shaman from other wizards is that the shamans are not magicians but physicians and sages, but the main feature that distinguishes them from other wizards and priests is the serious attention of the shamans to the semantic space. So all shamans are healing wizards, but not every witch is a shaman. In fact, a semantic space has caused the school of shamanism to enter the field mysticism. The very important point is that the last feature that allows a person to be a shaman is to enter the world of semantic space. Until the shamans reach the strict rituals and succeed in these stages, and after entering the world of semantic space.
Otherwise they will not find the entrance to the world of shamans the importance of semantic space in shamanism lies in the fact that all functions of the shaman are related to semantic space in one sense. In this way the shaman can communicate with the helpers and guardian spirits of the gods for diseases, wander the soul, stealing the soul or conquering it and ask them for help in pact, shamans are also witches, sages and sorcerers.
Like all doctors, he is able to heal ad, like all wizards, he can do extraordinary things. (Eliade, 1382: 129).

Field Findings of the Research
Until about a hundred years ago, before the gathering of the Turkmen tribes, a ceremony fairy readers was held inside the pergola, the mobile residence of the Turkmen tribes. The fire was always lit in the middle of it, and the fairy readers melted his sword or spatulas in it, struck the patient’s feet or body to drive the evil forces or infidel demons out of the patient’s body and soul.
In general, in the ritual of fairy reading sick sword is a symbol of removing or purifying the sick from the forces of evil and impurity. The semantic space and the connection with the spirits can be seen as two continuous stages, just like shamanism in the fairy reading ceremony.
Using musical instruments, performing rhythmic movements and spinning are the most important ways for fairy reading to enter the world of semantic space.
The fairy reading ceremony begins with apart (signer and musician) of Turkmen music playing the strings and singing some pieces of music that is specific to the fairy reading ritual. Perry first begins to shake her shoulders with rhythm and song. Then the rhythm of his movements becomes faster and turns into fast movements of the head and body and jumping.
This instrument immerses the rhythmic movements of the fairy singer in the semantic state of the space, and when this state reaches its speak, sometimes with a rope. Which hangs from the ceiling of the booth or room begins to rotate.
In this case, the somatic space reaches its peak and the fairy redder communicates with the world of Al and ghosts, in other words, he flies. Hunting or traveling in the form of an animal south is another feature of the ritual of fairy reading.
In the ritual f reading the fairy, the ram animal is a symbol in which the fairy singer travels to the world of ghosts and fairies, in other words, mixes with the spirit of the ram animal and goes hunting. Here the ram symbolizes the spirit of the protective spirit of the fairy.
In another stage of the fairy – reading ceremony, the fairy – singer, who is like a ram, pulls her horn and ties the patient’s hand and attacks him like a ram. At this point, Perry juam attacks the room with his head like a ram. He attacks goblins like a ram. According to him, goblins or black goblins attack in the form of ram movements.
Although the fairy does not make himself a ram, he travels and hunts in the form of an animal spirit. In most of the surviving lithographs of shamanism, although images of some animals can be seen, but images of many rams have been found that indicate its importance to shamans.
In Turkmen shamanism beliefs, spirits are divided into two categories, male and female. Female spirits are very powerful and dangerous and cause many ailments and diseases. According to the Turkmens, Al is a female soul, very beautiful and strong, tall and with long hair. Apparently, the male type is considered a benevolent spirit.
In addition to jinn and fairies, fairy readers also communicate with Al. in terms of fairy readers, the genie is a liar. Al does not lie; he tells the truth. The jinn have no sign of themselves but Al has a sign.
This sign is usually placed on the body of a fairy or patient (Nadimi, 1378: 63).

Conclusion
From Peri juan’s point of view, music has two important and special functions for him.
The main function of music, from the fairy reader’s point of view, is to control the forces that harass him. After the shaman stage begins, these pressures continue under normal circumstances and in everyday life to control these forces, the Pari khan go to the Bakhshies and ask the Bakhshies to sing Turkmen music in a friendly a private meeting to relax.
In ancient times, were sung and Khan agars narrated his to rical events. Turkish shamans always treated the sick along with the khanyagars and shamanic ceremonies have probably been accompanied by music performances since ancient times.
In the ritual of fairy reading as a remnant of shamanism, performing music is an important step in entering the world of semantic space fairy reading music brings inner peace to the Pairy, the patient and the audience.
Thus, fairy reading music has two main functions; first, the background of the semantic space and prepares the inner world of the Pairy reader, second, it stimulates the inner feelings of the patient and those present to perform the ceremony, and in general, prepares the space for the performance of the ceremony. 
 

Abstract
Many important materials throughout the world are composed of a variety of textiles, which are stored and presented in museum collections, galleries, and libraries. These textiles are one of the most important elements of cultural heritage and interpret essential objects that document the past human life, artistic creations, international trade, agricultural development, technological developments, and their cultural and social values.  As a result, it is necessary to study and apply suitable methods to protect and conserve these kinds of unique heritage textiles for our future generations. The method of conservation of these cultural-historical textiles is one of the most versatile branches of conservation and depends on various parameters. A number of bio-deterioration of cultural-historical textiles and also the disadvantages of conservation methods on these objects, human health and the environment, show the need for evaluating the bio-degradation mechanism of different microorganisms on these kinds of textiles and the use of latest methods for their conservation. In this way, the present work aims to investigate how cultural-historical textiles have been degraded, as well as the latest conservation methods. To achieve the purpose of the research, the qualitative content analysis method was used. The main research questions are what is the mechanism of biodegradability process of textiles? What is the importance of nano technologies in the protection of historical textiles? The results showed that one of the newest and most effective methods of protecting cultural-historical textiles against erosion caused by biological factors is the use of nanomaterials. These panicles have been intensively studied for various textile applications and demonstrated to provide multi-functional performance such as self-cleaning, release of dirty, protection against ultraviolet rays, antimicrobial properties, long-lasting, and multi-functional performance without compromising the intrinsic properties of the textile, which can be utilized to protect the cultural-historical textiles and slow down their degradation processes.

Introduction
Since prehistoric times and in all cultures, textiles have played an important role in the traditions and life. They have been considered one of the most important elements of cultural heritage that in different periods of a country history have usually been a number of antique textiles, such as decorative and artistic fabrics, clothing, carpets, tapestries, ecclesiastical vestments, woman’s belts, bags, and paintings. They are mainly obtained from tombs, archaeological excavations, mansions, crypts, sunken ships, and churches. Although, these valuable textile artefacts interpret essential objects that document the past human life, artistic creations, international trade, agricultural development, technological developments, and their cultural and social values but they are considered to be degradable materials due to a combination of various pollutions, biological, physical, environmental, and chemical parameters. The challenge has been to develop effective strategies for the conservation of these cultural-historical textiles, considering the strategies depend on several factors such as storage conditions, textile ages, the chemical types of their fibers and also their history period of use. There are different chemical and physical methods to protect from the historical textiles (Gutarowska 2017: 2388-2406; Karbowska 2011: 223; Sequeira 2012:  67; Valentin 1999: 85; Wirtanen 2003: 293). Nowadays, nanomaterials and technologies are becoming more important than the physical and chemical methods due to their multi-functional performance such as self-cleaning, release of dirty, protection against ultraviolet rays, antimicrobial properties, long-lasting, and also due to their multi-functional performance without compromising the intrinsic properties of the textile, which improves the conservation process of cultural- historical textiles and slow down their degradation processes (Lite et al., 2022: 610; Gutarowska 2014: 277; Lite et al., 2022: 609; Zambrano et al., 2020: 9817; Syafiuddin 2019: 794).
Following this tendency, there are several worldwide studies available on this regard but very limited studies have been done in Iran. These studies have been mainly investigated the effects of optimal environmental conditions, the atmospheric pollutants, and ultraviolet rays on the conservation process of textiles (Kianoush 2008; Samanian and Bahmani 2018; Hamzovi 2019). This is in while; the majority of Iranian studies have various drawbacks in terms of evaluating the bio-degradation mechanism of different microorganisms on the historical textiles and the use of latest methods for their conservation. In this regard, the present study attempts to disclose how cultural-historical textiles have been degraded, as well as the latest conservation methods by using descriptive and analytical method and also based on library information. 

Discussion 
The term biodegradation is defined as an irreversible process leading to a significant change of the material properties by the action of vital activities of microorganisms (through enzymatic or metabolic action)، (Zambrano et al., 2020: 9789). This biodegradation of organic compounds frequently causes the conversion of many of oxygen, carbon, nitrogen, phosphorus, sulfur components in the primary molecules to the inorganic products and also creates of new cell material. In general, stages of biodegradability of materials can be expressed in the following (Fig. 1)، (Nofal 2022: 5-6):
A) Primary stage: Substance chemical structure alteration resulting in substance removal of a definite property.
B) Environmentally acceptable stage: The biodegrading process to the extent of elimination of specific unacceptable compounds properties. This process is similar to the primary biodegradation approach, and it depends on the environmental conditions.
C) Ultimate is full compound decomposition or breakdown into simple molecules fully reduced or oxidized (such as CO2/methane, nitrate/NH4+, and H2O). 
The textile biodegradation process depends on the composition of the findings and the storage conditions and can occur slowly or quickly in the three following stages: 1) bio-deterioration and bio-fragmentation, 2) assimilation, and 3) Mineralization. (Lite et al., 2022: 608). Microorganisms digest the organic products of plastic degradation under aerobic or anaerobic conditions (Zambrano et al., 2020: 9790). The process of decomposing organic matter in the existence of oxygen is called aerobic bio-degradation. Anaerobic respiration is the practice of decomposing compounds by the action of microorganisms in oxygen absence and bacteria and fungi use the acceptor of an electron other than O2 as a chemical entitle (Nofal 2022: 7). 
Nanotechnology is revolutionizing materials science in a pervasive way, in a manner similar to polymer chemistry’s revolution of materials science over the preceding century. The continuous development of novel nanoparticle-based materials and the study of physicochemical phenomena at the nanoscale are creating new approaches to conservation science, leading to new methodologies that can “revert” the degradation processes of the works of art, in most cases “restoring” them to their original magnificent appearance (Giorgi et al., 2010: 695). The most intensely studied nano-structures for textile artefact conservation are metal nano-particles (AgNPs), metal oxides (zinc oxide, magnesium oxide, and titanium dioxide), hydroxide nanoparticles (calcium hydroxide and barium hydroxide) and modified nano-clays due to their remarkable antimicrobial properties, UV-absorbers, water-repellents, and dirt repellents (Lite et al., 2022: 609; Giorgi et al., 2010: 702-703; Palladino et al., 2020: 3). 

Conclusion
Our country, with its ancient history, is one of the most important centers with rich cultural-historical works in the world. A large part of these works are textiles which can be degraded using microorganisms due to their chemical structure. More and more studies are necessary for the field of historical textile conservation to preserve the memory of our predecessors, maintain up-to-date knowledge regarding new methods, and for future generations. Most of the studies conducted in Iran, have been investigated the effects of optimal environmental conditions, atmospheric pollutants, and ultraviolet rays on the conservation process of textiles. This is in while; the majority of Iranian studies have various drawbacks in terms of evaluating the bio-degradation mechanism of different microorganisms on the historical textiles and the use of latest methods for their conservation. In this way, the present work attempts to take a step towards the existing gaps. According to the results of this research, it can be concluded that the term biodegradation is defined as an irreversible process leading to a significant change of the material properties by the action of vital activities of microorganisms. This process occurs in the three stages i. e. bio-deterioration and bio-fragmentation, assimilation, and mineralization. The mineralization catabolic pathway depends on the environment where the microorganisms can grow and they digest the organic products of plastic degradation under aerobic or anaerobic conditions. During both processes, aerobic or anaerobic, microorganisms need a carbon source for growth and reproduction. 
In order to reduce the biodegradability of textiles, several physical and chemical conservation methods have been reported in the literature. The main method of preservation is maintaining the findings a microclimate to limit degradation by adjusting the brightness, humidity, and temperature of the area in which they are stored or exposed. Recently, special attention has been given to nanomaterials. Nanotechnology is revolutionizing materials science in a pervasive way, in a manner similar to polymer chemistry’s revolution of materials science over the preceding century. The continuous development of novel nanoparticle-based materials and the study of physicochemical phenomena at the nanoscale are creating new approaches to conservation science, leading to new methodologies that can “revert” the degradation processes of the works of art, in most cases “restoring” them to their original magnificent appearance. The most intensely studied nano-structures for textile conservation are metals, metal oxides, hydroxide nanoparticles, and modified nano-clays due to their remarkable antimicrobial properties, UV-absorbers, water-repellents, and dirt repellents.
