The purpose of this study is to explore the student perceptions of women's presidency within the Forum for National and International Awareness (FINA), which is the highest student governing body at Sherubtse College. This research will help to clarify the existing structure of the president at Sherubtse College. A purposeful non-random sampling strategy will be used to collect and analyze data, with a total of six selected students. Semi-structured interviews will be conducted using Facebook Messenger as the medium for data collection. While taking notes, the replies will be captured using Messenger's Audio function. The captured data will be meticulously analyzed using open coding, axial coding, and selective coding approaches. The existence of discrimination within students' views towards voting a woman president for FINA is expected to be determined through this extensive investigation. Furthermore, the study intends to offer insight on how common conventional views about women's inadequacy in leadership roles influence students' decision-making mentality, particularly when it comes to choose women to the leadership positions.

Objective: The main objective of this study is to know and understand the mind of every individual regarding gender difference and math anxiety influence on boys’ and girls’ performance in mathematics because many researchers have found out that there is no clear distinction on it.Method: 60 students were randomly chosen from a total of 1531 students in Sherubtse College to be the respondents in this study and enrolled in spring 2021. There were 32 males and 28 females among the 60 respondents. The quantitative method was used for this study as the data were reliable and generalized to a larger population. In addition, the stratified random sampling was and the participants randomly from the first, the second, and the third-year base on their gender were selected. Firstly, the descriptive statistical test was conducted SPSS software to examine the significant differences between independent variable that is gender and other dependent variables such Indicators of Math Anxiety (IMA-Total) based on Parkinson's Four Factors of Emotion Theory, Math Anxiety Questionnaire for Adults (MAQA-Total), and Mathematics Anxiety Rating Scale (MARS-Total) to observe gender differences regarding math anxiety amongst male and female students in the college.Findings: The statistical t-test determined that whether there was a significant difference in level of math anxiety between the two different groups such as male and female in general. The descriptive statistics indicates that there is no significant difference in math anxiety between male and female students however, there is a slight difference between gender and math anxiety in the college.Conclusion: The results of this study showed that there is no significant difference regarding math anxiety between male and female students of the Sherubtse College. Therefore, it can be mentioned that linking mathematics as a male dominance is incorrect and it is a stereotype because no such substantial difference was found in the study to reject the null hypothesis.

Communities Advancing Resilience Toolkit (CART) is a comprehensive surveying tool for assessing the community's resilience and identifying the strength and challenges of the community towards resilience capacity. The study assessed the community resilience of the hazard-induced urban community in Nigeria. The version of CART adopted enlisted 27 items of core community resilience and community attributes which represented critical components in an urban community and were randomly administered among urban dwellers. Survey outcome deduced that the domain "connection and caring" was deduced as the community resilience strength domain (mean= 3.18, SD= 0.38). In contrast, the item deduced as the strength of the community was "people feeling of belonging in the community", with the highest agreement of 63.3% (mean= 3.63, SD= 1.35). The domain "disaster management" was deduced as the community resilience challenge (mean= 3.06, SD= 0.63), while the item deduced as the challenge of the community was "community has services and programs to help people after a disaster", which recorded the lowest agreement and highest disagreement of 69.3% (mean= 2.13, SD= 1.13). The community attribute assessment items indicated that "necessary healthcare services availability" has the highest agreement (61.3%, Mean= 3.48, SD= 1.25) while the item "availability of leadership opportunities in the community" has the lowest agreement (42.7%, Mean= 3.32, SD= 1.24). Expanding the surveying process of the CART application can provide key information in a resilient building; hence, the need for continuous improvement on such application to further improve the study of community resilience.

Emergency preparedness requires actions from both institutions and individuals. Like a weak link in a chain, individual preparedness, behaviors, and predisposition to play an essential role in emergencies determine the level of effectiveness of such preparedness. This study aimed to assess the attitude, behavior, and knowledge of religious organizations (congregations) on emergency preparedness. The study was conducted using a cross-sectional research design, and primary data was collected with a questionnaire which was analyzed through descriptive statistics. Four hundred respondents (congregants) were sampled across the zonal headquarters of 5 major churches within the Port Harcourt metropolis. The result revealed that the significant source of information about emergency preparedness was television (38.25%), and churches are not prepared for an emergency (56.0%).Furthermore, most respondents never experienced any emergency (67.75%); however, perceived that churches are doing what they can to prevent emergency events around them (72.25%). The respondents indicated adequate knowledge about emergencies (66.5%) and perceived the collapse of a church building (26.75%) as the most common emergency associated with churches due to uncontrolled crowds (40.25%). The respondents (30.25%) revealed that discussing possible emergencies in the church is the most effective measure of emergency preparedness. In conclusion, individual emergency preparedness can be improved through changing attitudes and knowledge, which can be developed through continuous dissemination of information and engaging congregants in disaster drills and exercise to improve their experience.

The covid-19 pandemic has affected various areas of everyday life, especially young people. Many students studying abroad feel like they have been excluded in a foreign country and are fighting with their independence and fears at the same time. This research study aimed at conducting an ethnographic research on the experiences of students who were studying abroad during the pandemic. The research sample was consisted of 27 students from Greece who study in Cyprus. For the researchers' data collection; we used semi-structured interviews, in-depth discussions, and participatory observation. The main result of the study was the emotional surcharge to the individuals who felt excluded due to studying abroad. Students were forced to stay in the foreign country where they were studying with no support from the government. According to them, this fact revealed the lack of political will to consider their needs and their cultural background in order to design any support.

The purpose of this paper is to investigate the impact of ownership structure on the transparency of accounting information with emphasis on environmental uncertainty in companies listed on the Tehran Stock Exchange. The statistical population of this study is the companies listed on the Tehran Stock Exchange. After the restrictions were lifted, 174 companies were selected as the statistical sample size. The studied years are between 2015 and 2021.The findings of this paper are based on the fact that environmental uncertainty moderates the impact of ownership structure on transparency of accounting information. The results of the first hypothesis show that environmental uncertainty does not moderate the effect of government ownership on transparency of accounting information. Also, according to the second hypothesis test, the environmental uncertainty moderates the effect of managerial ownership on transparency of accounting information. Finally, the third hypothesis states that environmental uncertainty modulates the effect of institutional ownership on the transparency of accounting information.

Recent research highlights the importance of art in the educational process and its benefits in the holistic psycho-emotional development of the individual. Current literature focuses mainly on visual arts and music, while studies on dance and its contribution to mental health have increased only recently. The aim of the present study was to analyze recent literature that correlates the art of dance with mental resilience. In particular, the contribution of dance during school age was studied with particular emphasis on the mechanisms of development of mental resilience in students who are characterized by cultural diversity. This literature review was conducted in electronic databases, which was basically due to the restrictions imposed during the pandemic period. The duration of the study was 7 months, from November 2020 to May 2021. The results of the study showed that research activity on the effect of dance on mental resilience has not been adequately assessed. However, certain characteristics of mental resilience studied in relation to dance seem to contribute positively to the holistic psycho-emotional development of children by providing multiple benefits. It has been found that dance works beneficially and holistically across all ages, genders, socio-cultural, and socio-economic environments. It would be useful to plan more research to evaluate the effect of dance in greater depth and also in relation to more factors of psycho-emotional development.

Nearly at the end of 2019, the breakout of the COVID-19 pandemic posed an all-out challenge to human beings in the 21st century. In fact, it started to jeopardize people’s lives on an international scale. Since it is a global pandemic for which no effective vaccines have been discovered yet, it has involved many international organizations including the World Health Organization. Therefore, the main question is what the WHO—an authorized International organization—would do to conduct a balanced approach for tackling the new threats such as the COVID-19. The current situation necessitates adopting six approaches, i.e. gaining solidarity and accepting responsibility, keeping away the predicament of nationalism, globalism, communitarianism, and cosmopolitanism, identifying security and certainty as the permanent human requirements, avoiding being involved in cultural differences, and trying to end the quarrel between the global leadership and global-regional partnership. Hence, international organizations, especially the WHO, can play a growingly functional role in tackling this global challenge. The pandemic also introduces international sanitary needs that must be addressed from a professionalization perspective rather than a politicization one so that effective efforts will be made accordingly.

From historical times Indian society has seen atrocities based on the caste ideology. Caste has been studied from different frames by different intellectuals in academia and sociology and anthropology being an important discipline in studying it. Cinema as an art form and seen as a reflection of the society which represents the different aspects of the society through a cinematic lens gives the societal subject a totally different frame to see and observe the society for the people living in the same society where social problems like Casteism exists. Indian cinema has reflected the concept of caste through different angles and connotations like untouchability, honor killing in the situations of inter-caste marriage, and difference of problems in different locations like rural & urban and people dealing it with a difference. Thus, this paper focuses on and tries to understand the caste hierarchy represented in the cinema and the history and memory of Indian cinema. The study focuses on different decades of cinema generally from the 1980s to the current era and will try to explain how cinema has used the concept of caste in showcasing the practice and discrimination around it and the changes in the mindset of people while discussing the caste. For this work, a qualitative research method has been used. Films such as Achhut Kanya, Damul, Aakrosh, Sairat, Masaan, Court, Chandidas, Sujata, Ankur, etc from different decades have been studied and analyzed.

Translating irony has always been challenging as it relates to each nation culture and language background. So, to fulfill this job, special strategies are needed to guide the translators to find suitable equivalences for the first language ironies to be translated to the second language. In this research strategies for translating verbal and situational ironies in written texts are investigated. To narrow down the job, four short stories by Ernest Hemingway were chosen as the English written texts, namely; The Killers, Hills like White Elephants, Fifty Grand, The Snows of Kilimanjaro. For each story two Persian versions were considered: The Killers translated by Ahmad Golshiri and Reza Gheysariyyeh, Hills like White Elephants translated by Ahmad Golshiri and Araz Barseghian, Fifty Grand translated by Bahman Sholehvar and Sirous Tahbaz and The Snows of Kilimanjaro translated by Mohammadreza Khoubsefat and Shojaeddin Shafa . The model of translation strategies proposed by Mona Baker (1992) is considered as the framework. The result of the total frequency count of the strategies adopted in translating the ironies by the translators show that the most common strategies which are used by these translators to translate English verbal and situational ironies into Persian are using cultural equivalences and using general or neutral equivalences for English words and phrases.

The high capacity of gas hydrate in natural gas storage makes it attractive to use it for storage and transportation of natural gas and other gases as a competitor to liquefaction and condensation methods. Since the 1960s, when gas hydrate was introduced as a disturbing factor in gas pipelines, the idea of natural gas transfer by hydrate has been on the minds of many scientists. Because the hydrate transport temperature is higher than the liquefied natural gas (LNG) transport temperature, gaseous hydrate can be easily transported; Therefore, the technology of building hydraulic vessels will be much less complex than that of LNG vessels, and hydrogen production facilities can be designed much easier than LNG facilities. But the main problem is the smaller volume of gas transferred. According to studies in this field, each cubic meter of hydrate contains 175 cubic meters of gas. However, in LNG technology, the volume reduction reaches one hundred percent, and this issue is very important in the economics of gas transmission projects, especially long distances. Nevertheless, there is still great hope that hydrate will be used as a completely economical solution for gas transmission. In this regard, British Petroleum, in collaboration with other scientific centers such as the University of Gwasen, is building a small industrial unit that can produce 100 kg of hydrate per day.

In general, a gas hydrate is a combination of gas and water. For example, a group of mineral compounds are called solid hydrates. These are ionic solids that ions are surrounded by water molecules and make crystalline solids. In any case, in the gas industry, hydrates are a combination of a small molecule of gas and water. During the nineteenth century, hydrates remained an unknown and controversial topic. Early efforts were focused on understanding what compounds make up hydrates and under what conditions they form. During this period, many the constituents of hydrates were discovered. But it was not until the twentieth century that the industrial importance of gaseous hydrates proved. In the oil industry, the term gas hydrate refers to compounds that are usually gaseous at room temperature. These include methane, ethane, carbon dioxide, hydrogen sulfide, etc., and this leads to the term hydrogen and at the same time one of the most common misconceptions about these compounds. Obstruction does not cause much of a problem during normal pipeline operation. However, our unforeseen problems such as pump failure or obstruction problems in the transmission cause hydration and thus blockage of pipelines. It takes several weeks to remove these contractions. The purpose of this work is to investigate the phenomenon of hydrate decomposition in pipelines. A model has been discovered that is similar to the decomposition of hydrates in pipelines. The purpose of this work is to develop an optimal strategy for dehydration in pipelines with bilateral contraction.

Today, the number of obese people is increasing, and this problem, which in the recent past was considered a problem of developed and industrialized countries. It is now on the rise all over the world, including in developing countries, where food shortages are often the main nutritional problem. In addition, reducing the age of obesity and its prevalence in children and adolescents is also very important, because obesity at this age has a greater impact on health. In many cases, adult obesity begins in childhood, and effective prevention depends on how to deal with and control childhood obesity. Obesity in childhood and adolescence, especially during the second decade of life, is a strong predictor of adult obesity. The prevalence of obesity among children and adolescents is increasing in many countries around the world, even in countries where malnutrition due to malnutrition is still a public health problem. Accordingly, there is a close relationship between childhood obesity and the increased risk of adult obesity and the resulting physical problems. Today, overweight and obesity is a chronic disease that has become a health problem. It is one of the most serious public health challenges of the 21st century. According to the World Health Organization, 30% of the Middle East population is overweight. Today, overweight in children has become an epidemic, and in the age group of 6-12 years, overweight has more than doubled in the last decade.

< p>Underground gas reserves in the form of hydrates are a huge source of energy that researchers are looking for ways to extract. The amount of hydrate gas reserves is estimated at more than 1016 cubic meters, which is more than the discovered sources of other fossil fuels, if only 15% of this gas is extracted. But due to problems such as the slow rate of hydrate formation and the high pressure of its formation, his idea remained in the laboratory. After the discovery of hydrate self-preservation, this idea was raised more seriously and a lot of research was done on the use of hydrate for gas storage and transmission. High gas pressure is the most important negative factor in mass production of hydrates for gas storage and transport. The results showed that using these materials, methane hydrate is formed in much more suitable conditions than temperature and pressure. While the equilibrium pressure of methane hydrate formation at 293 ° K is about 34 MPa, with the addition of tetra-hydro-furan at a concentration of 2.5 mol%, this pressure is reduced to about 2.49 MPa, which shows a decrease of 92.6%. Also, at a pressure of 5 MPa, the equilibrium temperature of methane hydrate is about 278 degrees Kelvin, while at the same pressure, the fuzzy equilibrium temperature of a 6 mol solution of tetra-hydro-furan was about 306 degrees Kelvin.

Drilling mud is one of the most important components of rotary drilling, without which drilling is almost impossible. Drilling mud has many functions and applications, including cleaning the bottom of wells and transporting drilled debris to the ground, drying and lubrication of drilling tools such as drills, weight pipes and maintenance drilling pipes. From the wall of the well and create an impenetrable layer for the wall to prevent the entry of pressurized floors into the well to prevent the deposition of particles and weight-increasing materials of the drilling mud, while the drilling mud is stationary. Separation of drilled material after reaching the ground level Weight reduction of weight pipes, drill pipes and wall pipes according to Archimedes' law pointed to the hydraulic power of mud pumps to the drill. In this project, the goal is optimal hydraulic design for drilling mud. Due to the fact that in the optimal hydraulic design of drilling mud, the maximum hydraulic power and pump outlet pressure and well geometry are among the limitations, so the only parameters that can be used in the design are adjusting the pump outlet rate and size and number of drill nozzles. In this research, it was tried to design the optimal output rate as well as the number and size of drill nozzles to reduce the pressure drop and increase the hydraulic power of the pump.

Nowadays, scientists in physics, materials, etc. have come to the conclusion that if materials can be prepared in smaller proportions, the bonds that a small material makes with its surrounding phases are much stronger than larger scales. Nanocomposites were produced. In this type of composite material, at least one of the phases of the composite material is in nanometer dimensions. In the discussion of nanomaterials, nanocomposites have a special place. These materials have two or more nanometer components. The presence of particles and fibers in the structure usually creates strength in the substrate. In fact, when particles or fibers are distributed within a substrate, the forces applied to the composite are uniformly transmitted to the particles or fibers. Particles or fibers that are distributed within a substrate are called fillers. Properties such as strength, hardness, physiological properties, and porosity change with the distribution of fillers within the substrate. The substrate can hold the particles apart in such a way that crack growth is delayed. In other words, with proper distribution of fillers in the background material, the crack growth path in the background becomes longer and therefore crack growth is delayed. In addition, the components of nanocomposites have better properties due to the surface interaction between the substrate and the filler. The type and amount of these interactions play an important role in the various properties of nanocomposites such as solubility, optical properties, electrical and mechanical properties.

Background: In today's societies, empowerment of women and their full cooperation on the basis of equality, in all areas, including decision-making and community management is one of the requirements for sustainable development needed by our country. In a society where there is no equal and acceptable equality and fair cooperation between men and women in research, economic and cultural activities, nor is there fair opportunity for innovation and talent, the development process has not progressed as expected. Methods: Given the progress that has been made in the field of education and social participation of women in the country, no country can develop without the presence, cooperation and activity of half of its capable population. Increasing the presence of women in society will change their role. Many women entrepreneurs are playing a role in the international arena. Results: To achieve moderation and remove barriers to their growth and, as a result, to better expand society, we need women to be able to participate in the decision-making process in different areas of society. In many countries, these pursuits have led to significant success for women. Conclusions: Undoubtedly, the role of women in the Green Management (GM) System program for organizations and government agencies is vivid and a program of excellence, and that its full understanding and realization relying on involving all personnel of organizations and those interested in the development of the country.

Risk assessment has been considered as a scientific method for preparing and developing food quality and health standards. In recent years, the use of the word "risk" has become increasingly used in connection with food safety in general and with the health of food products in particular. This is due to the development of the use of the risk analysis system, the identification of critical control points of HACCP, which revolutionized the industries in the 1980s and 1990s. The first principle of the HACCP system stipulates that risk analysis must be performed. The hazards that are likely to occur must first be identified and then the severity of each hazard must be assessed and then the likelihood of those hazards assessed. These two factors (severity and probability of occurrence) talk to us about the possibility of danger. Another point about the importance of risk assessment is the increase in international trade, which raises new demands on food safety and quality. In the food supply cycle from farm to fork, food will always face countless risks that will lead to many problems for subsequent processes and end consumers. We all consume foods such as fruits, vegetables, dairy products, meat, bread, etc. on a daily basis, and our health depends on the health and safety of these foods. Today, many countries around the world seek to establish systematic management of food safety risk in order to provide safe and healthy food.
