The theorizing process in the field of bodily exercise processes is significantly based on Merleau-Ponty's concept of corporeality and sensory perception of the rehearsal process as a bodily function. In order to reach the body's understanding of the rehearsal process, it is not only necessary to explain the body in terms of philosophical paradigms, but it is also necessary to explain the characteristics of  Embodied/ Space- making rehearsal processes based on Merleau-Ponty's ideas. In this article, the intertwining of philosophy and practice is emphasized in order to understand  how a common ground and a new potential for understanding the training processes in body-oriented performances can be achieved, and in this field, a new conceptual approach can be used to understand the concept of physicality in the rehearsal process based on the training method. The purpose of this article is to explain the elements and characteristics of an Embodied/Space- making rehearsal method based on the concepts of Merleau-Ponty's phenomenology. This article, with a descriptive-analytical method and using library and internet resources, tries to answer the question of how, based on Merleau-Ponty's concepts of phenomenology, a suitable context can be found for the study, explanation and phenomenological analysis of the practice of creating space. Based on the phenomenological approach and Merleau-Ponty's ideas, the obtained result shows that in the training method of an Embodied/ Space- making rehearsal, the body of the "actor-performers" plays an essential role as an element of the template and the main platform of the process of creating events in the training process. This method of training by emphasizing the concept of "actor-performer" and the concept of "embodied reflection" suggests a method for the process of embodied training based on indicators such as "the embodied experience of actors-performers in the process of training", "the interweaving of self-other with each other in the position of subject-object in the lived world of training" ,"the bodily perception of the participants with all the components and elements and objects in the space/ rehearsal environment" and "the bodily/ sensory perception of the performers in the face of the world with which they interact" and highlights the rediscovery of the space/ rehearsal environment. In this situation, the actors-performers enter a state of being/ doing at that moment and continuously adjust themselves to the changes in the space/ rehearsal environment. This method creates countless expansion and diversity in the process of creating events that can be examined and analyzed based on phenomenology and Merleau-Ponty's terms.

In order to identify the dimensions and components of the elementary school’s curriculum, from the positive education perspective, initially from among all the sources and documents related to this perspective, 40 domestic and 30 international sources were chosen and analyzed and then a list of dimensions and components for content analysis of the curriculum was constructed. The gathered data were analyzed using the seven-stage model of synthesis and then evaluated by two evaluators whose measure of agreement was 0.78. The frequency of observing each component within the sources and its percentage was counted and calculated. The results show that the curriculum contains four dimensions of aesthetics, wisdom, morals, and instinct. Within each of these dimensions the following frequencies of categories was observed: 13 in aesthetics, 12 in morals, 12 in instincts, and 10 in wisdom. Thus, it can be concluded that the elementary school’s curriculum does contain components of positive education.

The present study focuses on optimizing the mechanical properties and microstructure of laser welding in Haynes 25 (L-605) cobalt-based superalloy. Initially, the influence of laser welding variables such as laser power, pulse frequency, welding speed, and pulse width on the mechanical and metallurgical properties of the weld joints is investigated. By examining the welding variables, the values of G (thermal gradient) and R (cooling rate) are calculated, and their ratio (G/R) and cooling rate (G×R), which predominantly affect the solidification microstructure, are determined. The structural correlation with the mechanical properties resulting from welding is examined.  In this research, it is considered to obtain the welding variables to create a high percentage of the structure in the form of equiaxed dendrite. Microstructural analysis reveals the growth of equiaxed grains and dendritic structures in the weld zone. The high cooling rate in the weld pool leads to dendritic solidification starting from columnar dendrites at the weld walls and ending in equiaxed dendrites at the center of the weld. The microhardness value in the weld zone is HV 328, which is very close to the microhardness of the base material. The tensile strength of the weld samples reaches about 93% to 94% of the base metal tensile strength. Tensile testing of the weld samples indicates a ductile-brittle fracture. Examination of the scanning electron microscope confirms the presence of dimples, intergranular cracks, and microvoids in the fracture zone.

Following theology, anthropology is undoubtedly one of the most important issues in mysticism, and mystics have had a unique perspective and interpretation in this regard. Abu Abdollah Neffari, as one of these mystics, has presented his mystical experiences in numerous verses in the two books Al-Mawaqef and Al-Mukhatabat, using a highly intricate language. Hence, his anthropological approach can be inferred from these intuitive reports. Human recognition in the thought of this mystic has various dimensions, one of which involves the discussion of the human in relation to this world. The main question of this research is as follows: What are the characteristics of “this world’s man” in Neffari’s mystical thought? With this aim, the authors, using a descriptive-analytical method, extracted and compiled the “anthropological” content of his mystical thought with a focus on the verses related to “worldly human”. They have concluded that Neffari strongly emphasizes that humans exist in the intermediary realm between “Haq” (Truth) and “Maseva” (Deviation from the Truth), and this position is the most important factor in human affliction and trial. He also does not limit the examples of “maseva” to metaphysical beings and considers some aspects of human existence as examples of “maseva”.

The land of China has long been the focus of historians and writers due to its vastness, history and diversity of culture and civilization. This research, looking at contemporary needs and necessities and relying on library sources and descriptive-analytical method, seeks to answer the question of what Muslim writers from the 3rd century Hijri to the middle of the 7th century Hijri provide knowledge about the economic situation and developments of this land. Muslims' knowledge about China at this point in time was based on personal observations, trusting other reporters, and in some cases based on stories and legends. One of the findings of this research is the attention of Muslim writers to goods, industries and mines, traditions and economic laws and routes, ports and commercial cities of China. The information that has good comprehensiveness and variety in terms of the subject and can tell the concerns, issues and economic attractions of this land from the point of view of Muslim writers.

This research was conducted with the aim of investigating the factors of strengthening writing skills from the point of view of the teachers of the first grade elementary schools in Baharestan city. The research method is applied in terms of the purpose and in terms of its nature, it is descriptive-survey. The statistical population of the study includes 150 first grade elementary school teachers in Baharestan city in the academic year 2019-2020. The sample was selected using simple random sampling method; 108 people were selected based on Cochran's formula and they were tested using a researcher-made questionnaire. The construct validity of the questionnaire was examined using exploratory factor analysis. Also, the reliability of the questionnaire was estimated using Cronbach's alpha coefficient. To analyze the data in order to perform descriptive and inferential statistics, SPSS24 software was used. In addition, in order to investigate the factors of strengthening writing skills, the second order confirmatory factor analysis method was used via structural equation modeling in Amos24 software. The results show that, based on the teachers, all the components related to writing skills had significant effects on strengthening the students' writing skills (p<0.05) .

The present study was conducted with the aim of determining the effectiveness of the curriculum based on positive education on the academic motivation, academic enthusiasm and academic well-being of elementary school students in the social studies course. The current research method was quasi-experimental and in the form of a pre-test-post-test design with a control group. The statistical population included all primary school students in Tabriz city, and the statistical sample, due to its semi-experimental nature, included 30 people (15 people in the experimental group and 15 people in the control group) who were randomly selected in a multi-stage cluster. In order to collect data, Harter's academic motivation questionnaire (1980), Fredericks and Blumenfeld's academic enthusiasm questionnaire (2004) and Tominin-Sweeney et al.'s academic well-being questionnaire (2012) were used, and univariate and multivariate covariance analysis were used to analyze the data. . The findings of the research showed that education based on positive education has a positive effect on academic motivation (internal motivation and external motivation), academic well-being and academic enthusiasm. Therefore, it is possible to increase the level of internal motivation and external motivation, academic well-being and academic enthusiasm of students by using curricula based on positive education

Febrile seizures are the most common cause of seizures in children under 5 years of age. Central nervous system infections are an important differential diagnosis of febrile seizures. Apart from infections, CSF characteristics are affected by many factors including the cause, type and duration of seizures. This study was designed to determine the cerebrospinal fluid (CSF) indices, including white blood cells (WBC), polymorphonuclear cells (PMN) count, and levels of protein and glucose in the CSF of children with fever-induced seizures.

The present study is a descriptive study that evaluated the results of CSF analysis in 56 children with febrile seizures admitted to Imam Sajjad Hospital in Yasouj from March 2012 to 2013. In the present study, CSF analysis was performed in children with a diagnosis of febrile seizures. In order to collect information from a pre-designed form that includes demographic information (age and gender), degree of fever, and information related to CSF indices including WBC, PMN and levels of protein and glucose in CSF, which have been extracted and recorded, statistical methods are used in this study to express descriptive statistics such as mean, standard deviation, number, percentage, etc.

56 children with a diagnosis of convulsive fever with a mean age of 21.4±14 months were evaluated. 37.5% (21 individuals) of the study population were females and 62.5% (53 individuals) were males. Among them, 33 individuals had low-grade fever and 23 individuals had high-grade fever. In 10.7%, the number of WBCs was more than 5. The amount of protein obtained was in the normal range, between 20 and 50 mg/dl, in 57.1% of cases. However, a significant percentage (39.3%) of CSF liquid protein was below 20 mg/dl. CSF fluid glucose levels were within the normal range at 91.1%.

Based on the results of this study, febrile seizures may be associated with low protein levels in the CSF. However, due to the limited sample size in our study, similar studies with higher sample sizes are recommended.

Antibiotics are extensively utilized and constitute a significant portion of hospital drug expenses, posing challenges due to their overuse. Among hospital wards, the intensive care unit (ICU) is a major consumer of antibiotics. This study aimed to assess the antibiotic prescription rates within the ICU wards of Namazi Hospital in Shiraz. 

We retrieved and analyzed electronic prescriptions from all 16 ICU wards at Namazi Hospital in 2020. The data were collected using a checklist that included patient demographics, prescription date, and the number of prescribed antibiotics. The relationship between antibiotic groups and patient demographics was assessed using Chi-square test.

Out of 381,003 electronic prescriptions, 67,002 (17.6%) included at least one antibiotic. Additionally, 5,056 patients (98.9%) received antibiotics. Analysis of the prescriptions revealed that most antibiotics were prescribed for male patients and those under 15 years old (P<0.05). Patients admitted during the winter also received the highest rate of antibiotics (P<0.05). The most commonly prescribed antibiotic groups were beta-lactam and chloramphenicols (32.89%), cephalosporins (19.28%), and glycopeptides (18%).

While less than one-fifth of prescriptions included antibiotics, nearly all patients received them. It is advisable for future studies to evaluate antibiotic prescribing based on prescriptions to provide hospital managers with more precise statistics, enabling appropriate actions for antibiotic stewardship.

Febrile seizures (FS) are the most common cause of seizure in children. In order to prevent FS and their recurrence, the recognition of the related factors to recurrence of FS is important. According to the high prevalence of FS and iron deficiency anemia (IDA) in children and that IDA is a possible risk factor for FS, as well as controversies in previous studies in this field, in this study, the relationship between iron deficiency anemia and FS in children was investigated.

This is a case-control study that investigates the relationship between febrile seizures with anemia in 150 patients aged six months to five years with fever who were admitted to Imam Sajjad Yasouj Hospital, from April to August of 2014. In this study, 75 patients with febrile seizures (case group) and 75 febrile patients without seizures (control group) were compared. Cause of fever (urinary infection, gastrointestinal infections, upper respiratory infection, lower respiratory infection and other causes), Information about blood cell count (white blood cell (WBC) and red blood cell (RBC), hemoglobin (HB), mean red blood cell volume (MCV) and serum ferritin level in patients with hemoglobin below 11 were recorded.

The mean age of the study population was 21.4 14 months. 34.7% of the study population were girls and 65.3% were boys. In this study, 10.7% of the cases and 8% of the controls had IDA. Although the prevalence of IDA was higher in the FS group, this difference was not significant (P=0.58). Also, HB and MCV were not significantly different in the two groups (P=0.49, P=0.69). In addition, the mean serum ferritin level in the FS group with anemia and the FS group with anemia did not show a statistically significant difference (P=0.94).

According to the result of this study, IDA is not a risk factor for seizures in febrile children.

Hospital managers are one of the key decision-makers in the implementation of health information systems. This study aimed to determine the implementation challenges of health information systems based on the hospital managers’ perspective.

This descriptive-analytical study was conducted in 2019 on the hospital managers of three provinces (Kerman, Yazd, Sistan and Baluchestan). Data were collected using a self-administrated questionnaire. The face validity of this questionnaire was approved by experts in health informatics and health information management and its reliability was confirmed by Cronbach’s alpha (α=96.7%). Data were analyzed using SPSS. To investigate the relationship between the mean of each challenge with demographic variables, Pearson, Independent T-test, and ANOVA tests were used.

In this study, the factors related to ignoring the hospital manager’s needs in system selection (1.333 out of 2 points), hardware purchase cost, insufficient user training to using the system (1.238), inadequate manpower and health informatics specialists (1.19), software purchase cost, insufficient financial resources (1.142), high cost of system launching, the lack of integration and interoperability among information systems, lack of support from health care professionals (1.047), and lack of management experience in choosing the best system (one out of 2) had the highest scores (out of 2 points). Also, personnel training costs to work with the system (-0.092) and Lack of improvement in work processes (-0.047) obtained the lowest scores. Data analysis showed that managers with clinical backgrounds considered financial and human challenges more important than non-clinical managers (P<0.031).

The hospital managers believed that financial, human, technical, managerial, and organizational factors are the most important challenges in implementing health information systems in Iran’s hospitals respectively. The health policy-makers and planners at large and small levels can address many of the challenges before implementing systems by focusing on identified priorities.

In this regard, during the presidency of Seyyed Mohammad Khatami, from the perspective of the issue of structure-agent interaction, we see a structuralist approach to Iran's foreign policy in the perspective of the Orientalist model. Because although Khatami was critical of some of the unjust conditions prevailing in the international system, he accepted the basic framework and structural requirements of the international system.Therefore, with the hypothesis that the foreign policy construction of the seventh and eighth governments in the face of international issues and powers has been influenced by Orientalist knowledge, and also with the content analysis, we address the questions of why foreign policy construction The seventh and eighth states are based on Orientalist knowledge? And the components of Orientalist policy-making in which axes of foreign policy production of the seventh and eight governments can be identified? Moreover, now that the various aspects of this approach and its most important components and examples have been exposed and judged, it seems that the structuralist approach based on its acceptance as a subordinate power is not only incompatible with human nature and Islamic thought. Nor will it be able to pursue the national material interests of its claimant.

Researchers have focused on entrepreneurial intention and contextual and individual factors affecting it as a robust theoretical framework for explaining entrepreneurial behavior. This study investigated the effect of creativity, autonomy, and workload with the mediating role of attitude on the entrepreneurial intention of students in a coherent framework. This research is an applied study in terms of goal, a quantitative study in terms of approach, and a descriptive-correlational study in type. The statistical population included all humanities students at Shahed University out of whom 340 people were selected by the simple randomization technique. The data collection instrument was a standard questionnaire. Data were analyzed by structural equation modeling with partial least squares (PLS) using the SmartPLS software package. The results showed that attitude and creativity had a significant and positive effect on students' intentions, but autonomy did not have a significant effect on the intention at the 95% confidence level. The workload had a significant and negative effect on intention and attitude. The mediating role of attitude was also confirmed. The findings provided evidence for the importance of creativity and autonomy in the formation of entrepreneurial intention among students. It was argued that attitude could act as a mechanism to transform creativity and autonomy into the intention. Therefore, it is suggested to the policymakers in the education systems to create a supportive environment and appropriate training to overcome the challenges of entrepreneurship and seek to create a positive attitude towards entrepreneurship in creative students.

"Ontology" is one of the important topics in the field of philosophy and mysticism in which mystics have had a special view and interpretation. Abu Abdullah Neffari, as one of these mystics, has presented the report of his mystical experiences in two books, "Al-Mawaqif" and "Al-Mukhatabat" in numerous sections and in a very complex language, and his ontological view can be deduced from those matters. The question of this article specifically is, what are the characteristics of "ontology" in Neffari’s mystical thought? In this article, the authors have extracted and compiled the "ontological" content of his mystical thought through a descriptive-analytical method and have come to the conclusion that Neffari -based on the division of existence and naming it "Maswa" and "letter" and symbolizing the beings of The world- has expressed his contents and also has given a hierarchy to the universe which are "low", "middle" and "high" and has described attributes for each order. These levels are hierarchical. He believes in the duality of existence from both aspects of "creatures" and "Godhood", and he believes in the phenomenological and mirror aspect of existence for the transcendent, in the "middle" and "higher" levels, and also he paid attention to the issue of veils in behavior for the mystic in the universe. “Speaking” is another rule of existence in his mind.

“Theology” and relationship with God is the most significant issue in mysticism, and mystics have had a special view and interpretation in this regard. Abu Abdullah Neffari, as one of these mystics, presented his mystical experiences in several sections of two books, Al-Mawaqif and Al-Mukhatabat, in a very complex language from which his theological view can be inferred. What the characteristics of “knowing God” in Neffari’s mystical thought are is the question addressed in this study. The author, adopting a descriptive-analytical research method, extracted the “theological” content of Neffari’s mystical thought and concluded that Neffari strongly insisted on the inability of man to know God; nevertheless, to him, this does not mean “divesting” God of His attributes and declaring His incomparability or transcendence. Relying on the inability to know God, he reveals the “holy ignorance” in knowing God. In fact, he holds a special transcendental view in this regard. According to Neffari’s beliefs, it is God who identifies Himself to His servant. He has used the term "Taarrof" in this context. The final part of the article addresses the issue of how to communicate with God.

The main aim of inventory control and production planning problems is to optimize the economic quantity of the order or determine the size of the production batch according to the capacities and limitations to minimize the total costs related to the order, purchase, maintenance, and delivery. The Economic Order Quantity (EOQ) model has been widely used to determine the order size or purchase of parts in production systems. Simultaneous consideration of the time and amount of ordering goods and minimizing system and customer costs is the main concern of inventory management. The assumptions of the classical EOQ model do not cover all inventory control systems in real terms. Leaving aside some of the assumptions, this paper aims to optimize and develop the EOQ model. The inventory system of this paper includes products that are capable of growing during the replenishment period, such as livestock. Also, it is assumed that the products of this system have a stochastic demand and a certain part of them has a lower desired quality. Newborn items are also ordered live and fed until slaughtered to the customer's desired weight and then slaughtered. Before all slaughtered items are sold, these products are screened to distinguish high-quality items from lower-quality items. To determine the optimal inventory policy, a model is proposed in this paper to maximize the expected total profit.

Design/methodology/approach: 

The studied inventory system examined the situation in which a company orders a certain number of items, e.g., chickens, that are in stochastic demand and are capable of growing over time. To maximize its total profit, the company should determine the number of goods that can be ordered at the beginning of a growth cycle. Total profit was defined as the difference between total revenue and total cost. Total revenue included revenue from the sale of items of good and lower quality, and the total cost included the total cost of purchasing, feeding, maintaining, setup and screening. The proposed model addressed two questions related to the order quantity and the order time. The objective function of the model was the expected total profit, while the decision variables were the batch size and cycle time, given the constraint that the total growth period and the facility setup time must be less than the consumption period.

In this study, a model of growing economic order quantity was proposed, which was expressed using a hypothetical numerical example. It was assumed that there is a company that buys day-old chicks, feeds and breeds them until they reach the desired weight, and sells them after checking the quality. Given sample quantities, the company should order 175 newborn items at the beginning of each cycle. Newborn items should grow in a period equivalent to 0.0941 years (34 days) and a period of consumption equivalent to 0.1928 years (70 days). The order must be registered every 0.1928 years (70 days) and the company expects to earn 42.2460 monetary units, annually. Quality screening should begin immediately upon consumption and occur over a period equivalent to 0.0499 years (18 days), after which imperfect quality items should be sold in a single batch.

Research limitations/implications: 

The proposed model can be extended by adding variables such as inflation, trade credit financing, allowable shortages, breakdowns, and quantitative discounts. Also, in the inventory system of this study, it was assumed that the screening process was 100% effective in separating items of good and lower quality. This issue, together with the learning effects on the screening process, suggest other potential areas for further model development.

Originality/value: 

In this paper, the assumptions of the classical model about the non-growth of items, good quality and equal to all products, and deterministic demand were discarded. Also, due to advances in technology and the existence of competitive markets, it was not possible to determine the exact amount of demand for firms. Considering stochastic demand as a way to deal with this uncertainty was inevitable. Therefore, it seems necessary to study this issue and propose a solution to remove the existing barriers in a way that in addition to providing the right amount of order, the profits of companies become maximized. The results of this study can be useful for all cases and units that have growing items and help to issue the right amount of orders, resulting in lower costs and higher profits.

Abdul Jabbar Niffari is one of the unknown mystics of the fourth century (AH). One reason for his anonymity is his complicated mystical prose. His most important works are Al-Mawaqif and Al-Mukhatabat, which contain direct reports of his mystical experiences. The explanations in these two books are chiefly devoid of conventional scientific terminologies of that era. In fact, these reports are based on direct quotations from God. The purpose of this study is to examine the content of these two books via an analytical-descriptive research method to see which characteristics of “Sufi-deconstructed texts" correspond to Niffari’s two books. Subscribing to the famous classification of mystical texts into two categories of "deconstructed" and "constructed", the main question of the research is whether the books of Al-Mawaqif and Al-Mukhatabat can be considered "deconstructed prose". By examining the main features of the deconstructed texts and presenting evidence from these two books, it was concluded that they should be categorized as deconstructed texts.

Due to the fact that excellence models, especially EFQM, work based on RADAR logic, which makes them heavily rely on subjective judgments, the aim of this study is to present a more accurate and objective way of assessing organizations with EFQM using Neutrosophic logic approach to minimize estimation errors of assessment values. In this study, assessing organizations based on the EFQM excellence model is performed using Neutrosophic logic, which is a three-valued logic useful in studying uncertainty. First, an assessing tool is designed for evaluation with Neutrosophic logic. Its validity of structure and content was confirmed using EFQM model framework and experts' opinion of evaluation. Also, the reliability was supported in a similar manner using experts' views. Then, the selected organizations, including three state-owned, private, and semi-public banks, were assessed with the assessing tool, and finally, the results of assessing with RADAR logic and Neutrosophic logic were compared. Based on assessing experts of EFQM National Excellence Award and calculations, assessing studied organizations with Neutrosophic logic approach proved more accurate than assessing with RADAR logic approach.

This study was carried out to identify and rank factors affecting the success of knowledge management implementation in the gas organization of Khuzestan Province by the Analytical Hierarchy Process Method.

The research method was descriptive- exploratory. The statistical population included all managers and senior experts of Khuzestan Gas Company, 35 of whom were selected by snowball sampling. The data gathering tool was a researcher-made questionnaire. The face validity of the questionnaire was confirmed by the professors and managers of Khuzestan Gas Company. Cronbach's alpha method was used to determine its reliability, which was estimated at 0.877 and 0.892. In this study, SPSS and Expert Choice software were used to analyze data from descriptive and inferential statistics.

Based on the Delphi technique, 6 factors and 33 important factors were identified. The results of the analytical hierarchy process show that in terms of importance, management and leadership factors, information technology, organizational culture, organizational structure, human resource management, and processes and activities factors were ranked first to sixth.

According to the results of this study, we can use the decision model derived from identifying and ranking of factors affecting the success of knowledge management implementation in the gas organization of Khuzestan Province by Analytical Hierarchy Process Method to improve and enhance the competitive position of the company. According to the findings obtained from the priority of agents, creation, and development of technological infrastructure,  application  of  knowledge - based  strategy  in  formulating  company  plans  andproviding appropriate information systems for storage, transfer, and exchange of knowledge, the rule of creative and critical thinking in culture, engagement, development of social relations between working and business communities as well as informal relations among company employees to increase satisfaction and motivation of knowledge transfer and other knowledge management processes to improve and enhance the company's competitive position in knowledge management development can be implemented and run.

The utopian idea The political thought in two stories 'Noon wa Al-Qalam' by Jalal Al-Ahmad and Rahla Ibn Fatumeh by Najib Mahfouz is based on the negation of the status quo, the existence of a crisis, and the attempt to idealize things. In both stories, using symbolic language and Sufism, writers are trying to present an image of an ideal society. They both believe that utopia can be achieved but the main obstacles on the way are the rulling of government and the seizure of power by certain individuals. Both writers use a symbolic language, with the difference that the noble language of the Arabic work is the literary language influenced by the classical works of Arabic literature, while al-Ahmad has chosen folk language for his narrative. Al-Ahmad's story, in its narrative, uses a type of Sufism whose social aspect is strong and its followers, or Qalandars, seek power but having faced with its difficulties, they resort to the way of the former power-owners but are defeated by them. Although seeking martyrdom, the protagonist of the story is eventually exiled. But Najib has applied a specific aspect of Sufism in the story, namely, the cutting off from the material world and its defects and the discovery and intuition of meditation and austerity. The main character of the story explores various lands in search of a way to solve his own homeland’s problems. He ultimately finds the way to prosperity in Sufism.

Various forms of Iranian drama throughout history and over time in the form of various genres emerged from the heart of rituals mourning and joyous ceremonies. In the meantime, the role of improvisation as one of the most important methods of performing Iranian happy plays, and especially Siah-bazi plays is undeniable. On the other hand, extracting the principles and rules of improvisation in various forms of joyful Iranian plays based on new theatrical methods, achievements and methods is one of the necessities of our play today. The main purpose of this study is to study various methods, and techniques of improvisation in the production process of Iranian joyful plays, especially Siah-bazi plays. This research has been compiled in a descriptive-analytical method and library and internet resources have been used to complete the basic information in this article; The main hypothesis in this study is that the study of various improvisation techniques and methods in various forms of Iranian cheerful performances, especially Siah-bazi plays, can increase the awareness, understanding and knowledge of “actors or performers” of improvisational performance capacities in this type of play. It also tries to answer the questions of what improvisation means and what are the different methods of dramatic improvisation? And how and in what process is improvisation used in Iranian joyful plays? And how and through what process do different improvisation methods and techniques manifest themselves in Siah-bazi plays? In conclusion, while defining improvisation and examining its different levels, methods and techniques, as well as introducing and explaining the structure of black play, improvisation methods in different forms of Iranian drama and Siah-bazi plays have been studied and it specified that learning and being Familiar to the some techniques and skills such as “actors’ experience in the process of improvisation”, “Expanding situations in the improvisation process”, “Performers’ relationship and their interaction with each other in the improvisation process”, “Group trust in the improvisation process”, “Verbal action in the process of improvisation” and “Non-verbal action in the process of improvisation” can increase the actors’ knowledge of the improvisational capacity of improvisation in various forms of Iranian juyful play, and specifically Siah-bazi play.
