Characterıstıcs of the organızatıon of extracurrıcular actıvıtıes
Authors: Agarahim Rahimova Manzila
Published: November 2022

The development of students' scientific and artistic thinking is a difficult and long process, so it should not be limited to lessons. Experience shows that extracurricular activities not only increase students' interest in learning, but also have a strong impact on their speech culture. It is true that extracurricular and out-of-class activities are not included in the school curriculum, but are based on the principle of voluntariness and are a kind of continuation of the work carried out in the classroom. This means that extracurricular and out-of-class activities differ from the teaching process only in their form and in their content. Therefore, teachers should pay serious attention to this issue. A well-thought-out education policy is very important in determining the future development of each country and strengthening it as an independent state. Education means the upbringing of our young generation in the national-spiritual spirit, the value of the nation, the development of the country. In this regard, the upbringing of adolescents and young people with intellectual potential is of great importance. Important and urgent tasks such as upbringing of teenagers and young people in a physically healthy, morally pure, spiritually rich national-spiritual spirit, their close association around the ideology of statehood are the priority policy and the main direction of our state today. The organization and conduct of extracurricular activities refer to important pedagogical principles. General and specific features should be kept in mind when organizing extracurricular activities. Taking into account these characteristics, a competent teacher achieves important results in the formation of student personality by ensuring the integration of lessons and extracurricular processes. The article analyzes the characteristics of extracurricular activities and comments on the problem in terms of students’ moral education.

Published: November 2022

The article analyzes the problem related to the formation of managerial competence of future directors of preschool education. The content of the concepts "competence", "managerial competence of the director of the preschool institution" is analyzed. Theoretical analysis of research of scientists who studied the problems of managerial competence in the theory and practice of management of educational institutions. It is noted that the modernization of the education system requires changes in management, as the current head of preschool education must be well versed in the field of management, competently manage the educational process in a preschool education institution, identify promising vectors of development that will affect the effectiveness of preschool education, implement effective methods of working with staff. The managerial competence of the director of preschool education institutions is defined as an integral property that includes a set of professional knowledge and skills that demonstrate a high level of professional competence in management, personally significant qualities that contribute to the implementation and performance of functional responsibilities, high motivation, efficiency and perseverance, self-development and self-improvement in the profession. It is noted that the director of a preschool education institution is primarily a manager who organizes and manages a preschool education institution and its functioning; the development of prestige and image depend on his / her professional skills and leadership qualities. The professional skills that the future director of preschool education institutions must master in the learning process include the ability to objectively assess his / her own knowledge (general, special), to effectively organize professional activities, to make decisions independently and be responsible for their results, to establish positive and effective subject-subject relationships with employees, to introduce innovations in the educational process, to strive for self-improvement and self-development. A questionnaire was developed, examples of exercises and tasks were given, which were considered with students of the second (master's) level of higher education in the process of studying the discipline "Theory and practice of work organization in preschool education". The obtained quantitative results showed that the developed set of practical tasks, which were considered with students, helped to increase the level of managerial competence of students, future heads of preschool education institutions.

Authors: Jingyi He , Rebrova Olena
Published: November 2022

The article presents the results related to theoretical modelling of the phenomenon “artistic and project-based experience” of future teachers of Musical Arts and the criteria for its evaluation. The formation of this type of experience on the basis of piano training aimed at future teachers of Musical Arts is actualized by the fact that projects become the most attractive innovative organisational form of teaching arts. Researchers explore various phenomena related to project-making (competence, skills, technology, activities, culture, etc.). However, artistic and project-based experience in the context of professional training aimed at future teachers of Musical Arts still needs theoretical understanding. The article clarifies the essence of this type of experience; the corresponding concept is interpreted as an integrated professional quality of future Musical Arts teachers; it is a process and a result of accumulation and memorisation of knowledge and practical skills enabling the embodiment of artistic and essence-related ideas into an organisational form perceived as an event where all participants are involved into independent preparing and performing of distributed creative tasks according to a certain scenario, focusing on achieving a common pedagogical goal. The structure of artistic and project-based experience is presented; it consists of four components: methodologically motivated component (aspiration to acquire methodical competence in piano performance; an interested attitude to mastering piano performance as a pedagogical resource of professional training); artistic and mental (the presence of the memory fund of artistic and project-related events and their reflection (artistic and project-based thinking)); activity-based and communicative (the presence of experience of artistic and communicative actions; activity in mastering the artistic and communicative resource of piano training); creative and self-organisational (experience of self-organisation in pedagogical project-making related to piano training; integrative and praxeological resources of the experience when dealing with artistic and figurative project-making and script-planning of events). The assessment criteria and indicators of the developed components are presented: motivational and intentional; information-based and operational; technological and innovative; productive and creative.

Published: November 2022

The system for measuring the fractional composition of wet-steam flow in the last stage of the LPC of an experimental steam turbine is presented. Wet-steam flow is a superposition of two fractions: primary moisture (formed by steam condensation during steam expansion in the flow path) and secondary moisture (formed by descending and crushing of water films discharged from the surface of turbine guides and rotor blades in the process of surface condensation). Determination of process moisture parameters (droplet size distribution and volume concentration) is based on measurement of optical transparency of the wet-steam flow. Registration of sizes and velocity of secondary droplets is based on pulse photo registration of the flow. The measuring complex consists of two types of optical probes (for registration of primary and secondary moisture parameters), units of measuring equipment, control computers, software and auxiliary systems. Operation of the complex is controlled remotely from a control panel. The presented system has been used for more than 20 years at the model turbine stand of JSC "NPO CKTI". The present work is devoted to measurements on experimental turbine ETPN-5 of JSC "Power Machines". Probes were installed before and after the last stage to register the parameters of primary moisture, and a probe measuring the parameters of secondary moisture was installed in the rim clearance. Experimental data on the distribution of the droplet size and wetness of the primary moisture along the height of the channel before and after the last stage are obtained. The distributions of erosion-hazardous droplets by size, velocity and direction of movement in the rim clearance are presented.

Published: November 2022

Issues related to the reliability of the electrical insulation system of high-load powerful turbogenerators with indirect gas cooling are considered and analyzed. The mechanisms of aging of the main components (main insulation, slot filling elements) of the insulation system under operating conditions exposed to electrical and thermal fields, and mechanical forces are studied. Modern ideas about the mechanisms of aging of main insulation and slot filling elements under the action of internal and external impacts (slot and spark discharges) are analyzed. The degradation of insulating materials during operation begins, first of all, in a weak local area of the main insulation, characterized by a large number of technological defects (cavities filled with gas), in which internal partial discharges occur. However, thermosetting insulation of high-voltage electrical machines can function normally throughout its lifetime in the presence of rather intense internal discharges. At the same time, no service life deterioration is observed due to the specific properties of modern main insulation, which contains a mica barrier. The greatest danger is posed by slot partial discharges (SPD) and vibration spark discharges (VS) that occur in the slot area of the stator winding. To reduce the intensity of these discharge processes, it is necessary to optimize the design of the anti-corona coating. On the basis of the performed analysis, a scheme was developed of the aging of the electrical insulation system of the stator winding of air-cooled turbogenerators. Based on the results of prototype tests, an estimated assessment of the "lifetime" of the electrical insulation system of the stator winding, developed using promising electrical insulating materials, was carried out.

Viewpoint Diversity at UNC Charlotte
Authors: Metzgar Matthew , McGowan Mary Jo
Published: November 2022

Introduction:
A number of recent surveys have shown that college campuses are becoming intolerant of different viewpoints. Part of the mission of any college should be to create a space where different viewpoints can be debated in a healthy, intellectual way. To gauge the campus climate at their own University, the authors deployed a survey to business students asking how comfortable they were sharing and responding to different viewpoints.

Methods:
Business students were surveyed for their attitudes towards diverse viewpoints. The survey instrument has been used at other colleges to survey students for several years.

Results:
A portion of students are censoring their views on controversial topics. There is often a reluctance to present honest viewpoints in the classroom.

Discussion:
Faculty needs to be mindful of the classroom environment they create. Colleges should be a major place where different viewpoints are discussed and debated.

Limitations:
Only business students were surveyed. There may be different outcomes for students in other majors.

Conclusions:
These results suggest that many students are self-censoring their views in class. Faculty should be aware of this and create an environment where different viewpoints are welcome.

Published: November 2022

Introduction:
The aim of this research is to design a tool (a scale) for measuring the quality of life of university students and to copy down its validity, use and reliability on six-dimension academic achievement: it touches family life quality, social life quality, personal happiness, life satisfaction and mental health.

Methods:
963 male and female students from the Faculty of Social Sciences, Department of Psychology, for the academic year 2018/2019 were exposed to the application of the model (factor analysis) and the reliability coefficient was reached by using Roland and Kettmann equation (.773) and Spearman-Brown (.776) and Cronbach’s Alpha (.629).

Results:
The feedbacks show that this tool for measuring ‘Quality of University Student Life’ is characterized and described as a good degree of stability.

Discussion:
When using “factor analysis” tool, we conclude that the exit dimensions focus on two basic axes: the first axis related to public health, quality of education, Family life, life satisfaction, and mental health. The second one consists of the quality of social life and personal happiness. Since these results have given a good degree to some extent, we were commended for working in favour of this tool (a scale) to judge the life quality of university students majoring in psychology faculty at the university.

Limitations:
The research and the questionnaire of the tool were applied to a group of psychology students at the national level which includes 963 male and female students with a percentage of 23.98%.

The questions of this tool were tested on a sample of 963 students at the national level who were randomly chosen from various disciplines of master’s degree in psychology. Research was conducted during the academic year 2018/2019.

Conclusions:
The targeted instrument designed in this research which is “the factor analysis” has achieves a good validity and stability and has driven to two basic scales.
Effects of oxidative stress, DNA damage, and inflammation in multiple sclerosis: A clinical perspective
Authors: Beyaztas Hakan , Uzun Mustafa , Aktas Selman , Guler Eray Metin
Published: November 2022

Multiple sclerosis (MS) is a demyelinating nervous system disease known for its lesions and manifests itself with attacks. According to some theories, inflammation and oxidative stress play an important role in MS. With this study, we aimed to examine the levels of oxidative stress, inflammation and DNA damage in MS patients and to get an idea about the course of the disease from these data. The research comprised patients diagnosed with MS between the ages of 18 and 60. Photometric techniques were used to determine serum native thiol (NT), total thiol (TT), total antioxidant status (TAS), and total oxidant status (TOS) levels. The oxidative stress index (OSI), disulfide (DIS) level, and percentages of DIS/TT, DIS/NT, and NT/TT were determined with mathematical calculations. Inflammation biomarkers tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-1 beta (IL-1β) were measured by photometric methods with commercially purchased ELISA kits. DNA damage was detected using alkaline single-cell gel electrophoresis. TOS, OSI, and DIS levels, as well as DIS/NT and DIS/TT percentages, IL-1β, IL-6, TNF- α and DNA damage levels were shown to be statistically significantly increased in MS patients than in the healthy control group (p < 0,001), according to the study's findings. Furthermore, TAS, TT, and NT levels were decreased in MS patients. Inflammation occurs as a result of oxidative stress in MS patients and causes DNA damage. Our results show that clinicians should consider oxidative stress, inflammation, and DNA damage when evaluating MS's development.
Searching for a Renewal of Religious Education Identity – A Swedish Perspective
Authors: Klintborg Caroline
Published: November 2022

In Sweden and in other parts of Europe, the nature of religious education (RE) and its place in schools is the subject of ongoing discussions. Concepts used in the RE classroom can either open or close classroom conversations. A growing consensus can be observed among researchers that the concept of ‘religion’ is not sufficient to describe – and give space to – the meaning-making of the diversity of individuals in society. As a result, discussions about worldviews have gained momentum. But not even the worldview concept – and the choice to frame the subject of RE with this addition – can solve the real problem, which is how young people can relate to the content of the subject in the first place. In this article the view is presented that the concept of existential configurations is equipped to adequately capture a complex and personal understanding of life that, not least, can be observed among young people today. Furthermore, it is argued that this concept of existential configurations gives access to a theoretical language that enables individuals to understand their own existential meaning-making, and to see how it relates to the plurality of religions and worldviews that can be encountered in society – even when they do not describe themselves as religious or as having a specific worldview.

Nigerian orphans face a range of challenges, including finding a suitable place to live, having to choose who to live with and this choice is influenced by various factors. This study determined the proportion of orphans’ resident in orphanages and family settings in selected states in Nigeria. It also assessed stakeholder’s input into placement option decision for orphans. The study examined orphans’ comfortability with residential placement and living with caregivers. The issues related to non-comfortability of orphans with residential placement were also investigated. The study employed the descriptive survey research design. The population for the study comprised all orphans in formal care (orphanages) and informal care (family settings) in Nigeria. A multistage sample procedure was employed. Five states were selected purposively in Nigeria. Indices such as poverty, high rates of insurgencies and HIV/AIDs were used in states’ selection. A sample of 1,475 in orphanages and 2,418 in family settings were selected for the study making a total of 3,893 orphans. Data was from a larger study on Needs and Vulnerability of Orphans in Orphanages and family settings in Nigeria. Questionnaire for Needs and Vulnerability of Orphans in Orphanages and Family settings in Nigeria was used to elicit information from the respondents. Data collected were analyzed using frequency distribution and percentages. The results showed that more orphans live in family settings (2,418) and orphans residing in both orphanages (30.5%) and family settings (44.2%) are staying there based on the decisions of relatives. As perceived by the orphans, (88.5%) in orphanages and (71.1%) in family settings are comfortable where they are living and (77.6%) in orphanages and (72.3%) in the family settings perceived that they are comfortable living with their caregivers. Finally, it was found out that most prominent of the issues related to the residential placement of orphans in the family settings were poor living conditions (49.7%) and access to resources (48.2%), while orphans in orphanages felt challenged with strict caregivers (46.2%) and lack of access to recreational facilities (16.2%). Based on the findings, it was suggested that families within the communities and stakeholders should support family members who are saddled with the responsibility of caring for orphans. It was also recommended that staffing patterns in orphanages should be restructured to enhance caregivers’ capacity to provide children with stable, warm, and consistent relationships.
Sidelobe level suppression for elliptical antenna arrays using modified SALP swarm algorithm
Authors: Kurt Erhan , Basbug Suad , Guney Kerim
Published: November 2022

In this study, a modified version of salp swarm algorithm (MSSA) is used to synthesize elliptical antenna arrays (EAAs). The original salp swarm algorithm (SSA) is an optimization algorithm inspired by the behavior of salps in nature, which is used to solve engineering problems. The main purpose of the synthesis in this study is to obtain an EAA pattern with low maximum sidelobe levels (MSLs) for a fixed narrow first null beamwidth (FNBW). For different examples, the amplitude and angular position values of the antenna array elements are considered as optimization parameters. To show the effectiveness of the MSSA, eight examples of EAAs with 8, 12, and 20 elements are given. The results obtained with MSSA are compared with those of the antlion optimization, symbiotic organizations search, flower pollination algorithm, and accelerated particle swarm optimization from the literature. It is clear from the numerical results that MSSA outperforms the other algorithms in terms of the suppression of MSL.
An intelligent barrier using ultrasonic technology
Authors: Janů Přemysl , Odvárková Barbora
Published: November 2022

The article is devoted to the complete design of an intelligent barrier that uses piezoelectric ceramic transducers as transmitter of an acoustic signal and as a receiver. There is a relatively rich device base on the market for these transducers. These transducers are also not economically demanding. The barrier is composed of three identical bars. A continues wave rectangular signal generation is used for excitation of the converters on the transmitting side. The receiving side is more complex. A signal from the receiving transducer is first analog pre-processed and converted to logical values of 0 or 1. Subsequently, these signals are processed in a microcontroller system, evaluated and a possible alarm of a presence of an intruder is signaled using a display, a light-emitting diode and a piezoelectric siren. The display also shows the number of alarms. Some intelligence is added to the system by classifying a potential intruder. The functionality of the system is verified in a detail and discussed.

The Summary for Urban Policymakers (SUP) initiative provides a distillation of the IPCC reports into accessible and targeted summaries that can help inform action at city and regional scales. This is a collection of the three volumes of the SUP series combined together.
Pitch–Plunge Equivalence in Dynamic Stall of Ramp Motion Airfoils
Authors: Miotto Renato , Wolf William , Gaitonde Datta , Visbal Miguel
Published: November 2022

Large-eddy simulations (LES) are employed to investigate the pitch–plunge equivalence of an SD7003 airfoil undergoing constant ramp motions at Reynolds number [Formula: see text]. The equivalence is constructed based on the geometric effective angle of attack according to the quasi-steady thin-airfoil theory. Two rates of descent (or pitch up) are analyzed for different Mach numbers in order to investigate the effects of compressibility on the evolution of the dynamic stall vortex (DSV). During the onset of the DSV and its transport along the airfoil surface, remarkable similarities are found between pitch and plunge in terms of flow topology, aerodynamic loads, and signatures of wall pressure and friction coefficients. However, these flow similarities cease at high-load conditions as the DSV becomes more susceptible to the peculiarities of the airfoil motion, manifested here by different trailing-edge vortices. Employing a correction for the rotation-induced apparent camber effect present in the pitching case, which results from the quasi-steady thin-airfoil theory, improves the agreement between pitch and plunge. However, it is not sufficient to assimilate their disparate trailing-edge systems. Results also demonstrate that the limit angle at which pitch–plunge equivalence remains valid decreases for higher Mach numbers.

Published: November 2022

Abstract The main objective of the work is to analyze the actuarial inequities of the Spanish disability contributory subsystem, something that had not been considered until now. It is understandable that these inequities are admissible in some cases, but it is more debatable that they can occur in certain groups, so in this work we determine not only where they occur but also to what degree. The concept on which equity revolves is the Internal Rate of Return, obtained from the data of the Continuous Sample of Labor Lives. Collectives have been found whose results seem contrary to intuition. Keywords: Actuarial equity, permanent disability, Continuous Sample of Labor Lives, Internal Rate of Return. Resumen El objetivo principal del trabajo es analizar las inequidades actuariales del subsistema contributivo de incapacidad español, algo que no se había planteado hasta ahora. Es comprensible que estas inequidades sean admisibles en algunos casos, pero es más discutible que se puedan producir en determinados colectivos, por lo que en este trabajo determinamos no sólo dónde se producen sino en qué grado. El concepto sobre el que gira la equidad es el Tanto Interno de Rendimiento, obtenida a partir de los datos de la Muestra Continua de Vidas Laborales. Se han encontrado colectivos cuyos resultados parecen contrarios a lo intuido. Palabras clave: Equidad actuarial, Incapacidad permanente, Muestra Continua de Vidas Laborales, Tanto Interno de Rendimiento.

Abstract This paper analyzes the individual behavior about retirement age in Spain and the relationship between effective retirement age, statutory retirement age, life expectancy and activity rate of the elderly population. It is shown that the current adjustment coefficients for retirement at different ages are not actuarially neutral, encouraging retirement at the statutory age. Using actuarial methodology, we stablish the optimal retirement age, under the criterion of the maximization of gross pension wealth, and the factors of actuarial equity by age that should be applied to achieve actuarial neutrality. Keywords: retirement age, actuarial neutrality, actuarial equity, gross pension wealth. Resumen Este trabajo analiza el comportamiento individual en cuanto a edad de jubilación en España y la relación entre edad efectiva, edad legal, esperanza de vida y tasa de actividad de la población mayor. Se demuestra que los actuales coeficientes de ajuste por jubilación a distintas edades no son actuarialmente neutrales, incentivando la jubilación a la edad legal. Mediante cálculo actuarial, en el trabajo se determina la edad de jubilación óptima, bajo el criterio de la maximización de la riqueza bruta por pensiones, y los factores de equidad actuarial por edad que habría que aplicar para lograr la neutralidad actuarial. Palabras clave: edad de jubilación, neutralidad actuarial, equidad actuarial, riqueza bruta por pensiones.
Regresión cuantílica como punto de partida en los modelos predictivos para el riesgo

Published: November 2022

Dado un nivel o tolerancia de riesgo, la regresión cuantílica es un modelo predictivo que ajusta el correspondiente percentil de la variable respuesta continua. Fijado un determinado valor porcentual, se identifica el efecto de cada variable predictora en la distribución acumulada hasta ese nivel de la variable dependiente. En este artículo mostramos cómo puede utilizarse esta metodología en el análisis de datos en el seguro de automóvil y proponemos una extensión de la regresión cuantílica inspirada en la necesidad de predecir la esperanza de la cola condicional. Para ello se han desarrollado rutinas específicas en R y se ha implementado un procedimiento de remuestreo para la aproximación de los errores estándar. La principal conclusión es que este tipo de modelos permite analizar qué factores inciden en el riesgo de accidente y pueden ser utilizados para mitigarlo o para valorarlo en el ámbito asegurador.
Cap & Trap and alternatives in price discrimination
Authors: Hirsh  , Hirsh Imogen , Assa Hirbod
Published: November 2022

Cap and Trap is a mechanism for smoothing rate change at policy renewal. However, this method still can expose an insurance company to a potential conduct risk. Individual clients could be overcharged or undercharged on an individual basis for their risk. This paper discusses alternative methods to better smooth prices with the aim of reducing the effect of price discrimination.
