Authors: Tsiuniak Oksana , Kopchuk-Kashetska Mariia , Dovbenko Svitlana
Published: April 2023

This article highlights the relevance of the problem of using coaching in the professional training of future masters of primary education under martial law. Theoretical analysis of scientific sources on comprehension of the definitions of "coaching" and "pedagogical coaching" is carried out; the essence, purpose, and tasks are revealed. It is noted that the purpose of pedagogical coaching is to reveal the potential for improvement of the expected learning outcomes, development of critical and logical thinking, formation of mobility, independence in decision-making, the desire for self-development, self-learning, and success in future professional activities among higher education students.

It has been found that the introduction of coaching in the system of professional training of future masters of primary education will serve the process of training competitive and competent specialists with formed values, beliefs, and priority goals. They are capable of making both personal and professional independent decisions and generating new ideas. This method also helps master's students to develop appropriate self-esteem and academic stress resistance. This is the basis of educational and cognitive activity in the conditions of wartime.

It is concluded that coaching belongs to innovative technologies of professional education; it is a powerful tool for personal and professional growth for future masters of primary education; it is a technology for organizing scientific and pedagogical research that promotes the implementation of a student-centered approach in higher education institutions based on trust, partnership, and mutual respect. It is also important to provide a comprehensive rather than fragmentary implementation of coaching to achieve the aims of professional education, improve its quality, and establish cooperative subject-subject relations between professors and students.

Authors: Bilier Oksana , Vasko Olha
Published: April 2023

The article considers the possibilities of modeling based on which a model of the development of creative thinking primary school students in the process of extracurricular work is theoretically justified and developed, which has three components: the first component is the parts of creative thinking, namely: creative imagination, the ability to speak new and associative and figurative thinking. The second component is the methods of development creative thinking, within the scope of the study they were defined as: educational and developmental methods, motivational methods and creative and productive methods. The third component is pedagogical conditions for the development of creative thinking. Pedagogical conditions included: activation of creative activity, which is realized through the activation of thinking, creative imagination, observation of each student; giving the teacher freedom of action to demonstrate his creative abilities while performing tasks aimed at developing creativity; the introduction of game moments that motivate the creative activity of students, give an opportunity to be realized in a more favorable, psychologically positive atmosphere; the ability to create a sense of satisfaction and joy from success in students, the development of creativity; creation of an art space: a classroom, relaxation art corners, a hobby workshop, a gallery of student creativity; the use of innovative technologies in the process of extracurricular activities, for example, project activities.

It was determined that in accordance with the characterized pedagogical conditions, it is appropriate to use certain groups of methods: educational and developmental, aimed at identifying the creative potential of students and directing it to the formation of creativity structural components; motivational, which should interest students in the process of learning about the new, unknown, actualize knowledge bases, promote active creativity in the process of extracurricular activities; creative and productive, which summarize the mastered material, reflect the quality and level of specific knowledge, skills and abilities acquired in the lessons; creative learning methods, which include those that are traditionally intuitive: brainstorming, empathy, etc.

It’s confirmed that within the framework of the implementation of this model, the main task of the teacher is to manage the processes of creative search: creating a situation of creative activity of primary school students, developing their imagination, associative thinking, the ability to understand patterns, the desire to constantly improve, to solve more and more complex creative problems.

Authors: Skomorovska Iryna , Kyrsta Natalia , Matishak Marianna
Published: April 2023

The article is devoted to the problem of the syndrome of professional and emotional burnout of teachers. The authors analyzed the main factors, indicated the symptoms of professional burnout, and established methods and means of prevention of emotional burnout in the teaching profession. The article describes the content of key concepts, the essence of the categories «emotional burnout», «stress», and «emotional exhaustion», and the emergence and understanding of related concepts in the scientific research of foreign scientists (A. Griffiths, S. Jackson, T. Kox, K. Maslach, H. Selye, H. Freudenberg, etc.). The results of the analysis of scientific works proved that stress has three stages of development: anxiety, resistance, and exhaustion, which can cause professional and emotional burnout in specialists in various fields. The basic symptoms are emotional exhaustion, depersonalization, and reduction of personal achievements. T. Cox and A. Griffiths (about 150) provided a more detailed analysis of the symptoms of professional and emotional burnout and distinguished three groups of symptoms – affective, cognitive, and motivational. The peculiarities of the raised problem in our country are revealed, taking into account the specifics of the teaching profession. The factors of professional burnout of preschool teachers are singled out, namely: high responsibility, daily mental overload, the excessive number of duties, high emotional inclusion, strict control of the administration, etc. Measures to prevent emotional burnout were presented in three aspects: professional and administrative (psycho-training, role-playing, business games, mentoring, a favorable psychological climate in the team, etc.), non-professional (a rational division of work and rest, healthy nutrition, physical exercises, self-regulation, establishing short-term and long-term goals, etc.). It has been established that a comprehensive approach to the prevention of professional burnout in preschool teachers should include correction of the mental, physical, and spiritual components of the individual’s health.

Integral Education Based on the Pedagogy of Unity
Authors: Kozubek Mariola Teresa
Published: April 2023

The article substantiates the opinion that integral education based on personalism covers all dimensions of personality development: physical, mental, social, cultural, and religious. The purpose of the study is to present the innovative content of integral education, expressed in the Pedagogy of unity by Chiara Lubich. The reflections on integral education, based on the interpretation of Lubich's texts and the experience of the Focolare Movement educational community, founded by her, describe the original directions of integral education in the Pedagogy of unity. It is emphasized that the concept of holistic education of the Pedagogy of unity, based on Christian ideas, is compatible with the trends of personalistic pedagogy and - although it originates from the religious message of the charism of unity by Chiara Lubich - is characterized by universality, developed on love, presenting it as a pedagogical value. Based on the results of the analysis of modern scientific sources, it has been proven that due to love, and mutual understanding in interpersonal relationships, effective communication is created at the social level, a person is elevated to higher spiritual values, and a harmonious educational environment is formed for self-assertion and freedom. It has been found that this direction of education makes it possible to build universal fraternity, peace, and unity. The author claims that the interpretation of holistic education in this context allows for preserving the unity of the human being and his/her harmonious development. The presented analysis of the features of integrated education by the pedagogy of unity does not diminish the general idea expressed in Chiara Lubich’s theory. New directions have been determined for further scientific research, both in the field of the hermeneutics of Lubich's works as well as in the field of scientific research of the educational practice of the Focolare Movement and educational institutions in various cultures of the world, oriented on the charism of unity.

The article reveals the theoretical and methodological foundations of blended learning technologies, describes the features of their implementation in the educational process, summarizes positive developments, and outlines typical problems. Researchers emphasize that the use of blended learning technologies determines the combination of different learning formats and teaching styles. It is indicated that mixed learning technologies are the best option for organizing the educational process when it comes to learning during quarantine or pandemic, martial law, limited access to classrooms, which requires teachers and managers of higher education institutions to use non-standard approaches and creativity in meeting educational needs and professional requests of education seekers. The article notes that the use of blended learning technologies in pedagogical practice helps to optimize partnership interaction in the "teacher-student" context, promotes the formation of digital competences, improves program learning results, and increases the effectiveness of the educational process in a higher education institution.
The Category of "Perception" in the Professional Activity of a Social Worker (Aesthetic Aspect)
Authors: Vasianovych Hryhoriy , Nahirniak Mykhailo
Published: April 2023

The professional activity of a social worker is multifaceted, in which the aesthetic aspect has a special place. The key reason is that it aims to reveal the personality with special needs, the beauty of human existence, its inexhaustible possibilities of cognition and self-knowledge, development, and self-improvement. It is especially important for a social worker to help such a person perceive this world adequately, sometimes even overcome the tragedy of their existence, live a full spiritual and social life, and realize their inner potential. Of course, all this requires the proper formation of moral and aesthetic, psychological and pedagogical, and general culture from the social worker. Instead, today the contradiction between man and his culture is becoming more and more obvious. There appeared even the expression "civilization without culture", which testifies to a significant decrease in the importance of the aesthetic in almost all spheres of human life, its gradual descent from the arena of strong social activity and moving to the periphery of public life, the loss of considerable civic attention to it. It is enough to say that the subject "Pedagogical Aesthetics" has not been taught for years in the system of humanitarian education, which includes its fundamental branch - social work. In our deep conviction, this hurts the consciousness of both social workers and their patients, especially in the aspect of aesthetic perception of reality.

Published: April 2023

This study is a small-scale action research on the problem of EFL/ESL students’ participation in group activities during the crisis of the COVID-19 pandemic. The main stages of the research were conducted in the academic year of 2020/21. The population of the study is twenty-eight Ukrainian secondary school students and three teachers. The research aims at designing a method for ensuring learner engagement in and equal contribution to the group project during distance learning. The methodological basis of this study is the theories of “The Model of Willingness to Communicate”, “Collaborative Learning” and “Social Interdependence”. The quantitative and qualitative data have been collected through the mixed-method approach, in particular via pedagogical observation, surveys (teacher interviews and student questionnaires), peer evaluation, and mathematical statistics (descriptive and frequency methods). The analysis of scientific pedagogical and psychological literature on student engagement during traditional (in-person) and distance (synchronous and asynchronous) learning, including the use of social networks in education (Viber, Zoom, etc.), helped to identify the main factors that affect learner engagement and equal participation in group activities, such as psychological (self-confidence, anxiety, shyness, and personality), group formation (group size, teacher/student-formed, and homogeneous/heterogeneous), monitoring (self, peer and teacher) and evaluation (peer and teacher). The results of this study demonstrate that the teacher greatly influences the success and equality of student participation in small-group activities. Identifying reasons for unequal participation in the target group of learners, considering students’ personality traits and individual needs, and using appropriate planning, organizing and monitoring strategies are the key to their active engagement and effective group work. The results of this study could be used by researchers and practitioners working in the sectors of secondary and tertiary education.

Authors: Kachak Tetiana , Blyznyuk Tetyana
Published: April 2023

The article highlights the peculiarities of the development of communicative competence of future teachers of special education in the context of their professional training. It is noted that communicative competence is a mandatory component of a teacher's professional skills, a clue to efficient interaction with students, and effective educational activities. Its structure includes language, speech and communicative competence. It has been proven that the key to the active and effective development of the communicative competence of future special education teachers, including speech therapists and correctional teachers, is the active use of effective methods and techniques aimed at forming knowledge of language norms and rules, rhetorical culture, speech and communication skills in various situations. Such knowledge, abilities and skills are formed in the process of studying the courses "Academic Rhetoric" and "Foreign language for professional purposes" while listening to and analyzing speeches, conversations, discussions and interviews with specialists; performing role-playing games and analysis of communicative situations; practicing the storytelling method; expressive reading and recitation of works; analysis and texts editing; preparation and delivery of speeches; development of methodological models, selection and creation of exercises and tasks for the formation of students’ coherent, correct, logical, expedient, expressive, figurative speech skills.

As a result of the empirical study, it was confirmed that the method based on the step-by-step development of communicative competence of future teachers is effective. In particular, it is about studying language material and enriching the active dictionary with professional vocabulary; improvement of monologic and dialogic speech, oral and written comprehension skills; mastering the norms of speech culture; active communicative activity and interaction in different situations with different target groups - students, parents of students, and colleagues.

Published: April 2023

High-frequency electromagnetic fields refer to electromagnetic waves with frequencies ranging from 100 kHz to 300 MHz. High-frequency medium heating has the advantages of uniform heating, rapid energy consumption, and environmental protection. While it has a wide range of applications, the use of high-frequency dielectric heating in the bamboo industry is rare. Understanding the influence of bamboo temperature rise rate in high-frequency heating could promote bamboo industry development. In this work, curved bamboo was tested with high-temperature energy for continuous heating. The influence of moisture content of bamboo, sample thickness, and high-frequency processing power on temperature rise rate were studied. The results showed that the water content of bamboo affected the temperature rise rate. The effect of high-frequency heating was highest when the moisture content of bamboo was close to 11%. The thickness of sample had little effect on the temperature rise rate, but the high-frequency power had a significant effect on the temperature rise rate. The temperature rise rate of the lower and higher frequency power levels increased slowly and was close to constant. The heating power was 11 kW, and the temperature rise rate was the highest.

Published: April 2023

To address the challenges associated with corn stover utilization and the synthesis of phenyl- and methacryloyloxy-based silsesquioxanes (SQs) with difficulty and poor controllability, the authors present a novel approach that combines advanced biorefining techniques and innovative chemical synthesis methods. Spirocyclic alkoxysilane synthesized from corn stover ash was subsequently utilized for the synthesis of phenylSQs. The resulting phenylSQs were then subjected to fluorine ion-catalyzed rearrangement with 3-(trimethoxysilyl)propyl methacrylate (KH570) to yield SQs containing phenyl and methacryloyloxy functional groups. Through manipulating the ratio of phenylSQs and KH570, the authors successfully achieved a desired ratio of functional groups on individual SQ cages. Optimization of the ratio significantly impacted product collection, with a range of 5.5:1 to 8.5:1 recommended for efficient and effective synthesis. This study represents an important advancement in the field of high-value conversion of biomass, offering an easy means of tailoring the structure of phenyl- and methacryloyloxy-based cage SQs.

Published: April 2023

The results of the use of photon strength function (PSF) of the model of two coupled damped oscillators (Two State Excitations, TSE) for the description of nuclear data for photoabsorption of electric dipole gamma-rays by atomic nuclei are presented. The response function widths dependent on gamma-ray energy were used instead of constant widths in the initial TSE model. It was demonstrated that such a phenomenological approach is a simple method for the description and prediction of the PSF with excitation of both low-energy (pigmy) dipole resonance (PDR) and high-energy giant dipole resonance (GDR). The best description of the experimental photoabsorption cross-sections is obtained at constant width in the PDR range and linear or quadratic energy-dependent width in the GDR range.

Authors: Hlushchenko A.V. , Andrieieva O.L. , Tkachenko V.I.
Published: April 2023

The paper proposes a method of controlled heating of a cylindrical plasma using the features of the Exceptional point. It is shown that the coupled system of plasma and dielectric waveguides is capable of generating exceptional points where their dispersion curves cross. By controlling the connection (distance) between the waveguides, it is possible to control the distribution of the electromagnetic field, both in the plasma and in the dielectric waveguides around the exceptional point. It is also shown that in the presence of dissipative losses in the plasma, the degree of heating of the plasma waveguide can be controlled by tuning the distribution and intensity of the exciting electromagnetic field in the coupled waveguide system, which gives a potential advantage among other methods of plasma heating. The results obtained in the work can be considered as an example of a new method of controlled plasma heating, which can be used to overcome the existing problems of controlled thermonuclear fusion.

Published: April 2023

This study aims to determine the effect of the intensity of secondary caregiver and parental stress on the socio-emotional development of early childhood secondary care intensity is the frequency of care where the other party cares more often than the biological parents. Here in after, parental stress is a condition where the primary care, in this case, the father or mother, experiences exhaustion in parenting. As of, there are two independent variables (secondary care intensity and parental stress) and a dependent variable (early childhood social-emotional development) with a linear regression technique. The secondary-caregiver intensity was measured based on self-reports from parents who reported the average daily routine regarding the intensity of care levels (whether more frequent primary or secondary care?). Furthermore, parental stress was measured using the parental role quality scale instrument to parents. Then, the measurement of children's social-emotional development is based on instruments from the Ages & Stages Questionnaire: Social-Emotional (ASQ: SE). The sample of this research was all parents of kindergarden X, and it was conducted by purposive sampling method. The use of statistical calculations that have been carried out with the linear regression method. The results showed that there was a significant effect of secondary care intensity and parental stress on children's social-emotional development using the ASQ: SE instrument. With this research, the author hopes that there will be further and in-depth research on social-emotional development with various other variables as well as conducting path analysis techniques in looking for a causal relationship between the intensity of secondary caregiver, parental stress, and social-emotional development of early childhood.

Published: April 2023

Prudent study and analysis of the religiosity instruments that have been circulating it are found that there are many variations of instruments measuring the religiosity of Muslims. This is due to differences in the conceptual constructs used by the researchers as the basis for developing such instruments. The use of concepts and instruments that are not based on Islamic religiosity has the potential to distance the measuring instrument from what psychological behavior to be measured, while the measuring instrument based on Islamic religiosity is also not yet fully solid, in line, and be close to each other with Islam. Dissatisfaction with the instruments based on the constructs and instruments of Islamic religiosity that have been compiled has encouraged researchers to develop religious instruments based on Islamic teachings in a precise and solid manner. This instrument is called the Kāffah of Islamic Scale (KIS). The results of the psychometric test and empirical data show that the Kāffah of Islamic Scale (KIS) has a good factor structure through the testing phase of the unidimensional fit model. The Kāffah of Islamic Scale (KIS) measuring instrument consists of five dimensions, namely belief, formal ritual, interpersonal, personal, and morality. There are 33 valid items to measure the Islamic construct of the kāffah composed of five items representing the belief dimension, six items representing the formal dimension of ritual, thirteen items representing interpersonal relationships, twelve items representing the personal dimension, and three items representing the morality dimension. Overall, the results of this research provide preliminary evidence to support the use of the Kāffah of Islamic of Scale (KIS) as a measurement tool that has conceptual and psychometric strengths.

Published: April 2023

Bevezetés:A myocardialis izomhíd a koszorúereken gyakran kimutatott, jóindulatúnak tartott, veleszületett eltérés. Egyedülálló abban a tekintetben, hogy dinamikus kompressziót okoz az adott érszakaszon.Célkitűzés:A közleményben arra kerestük a választ, hogy melyek és hogyan vizsgálhatók azok a morfológiai és funkcionális jellemzők, amelyek meghatározzák a myocardialis izomhíd tünetképző voltát.Módszer:A rendelkezésre álló invazív és nem invazív vizsgálómódszerekkel a morfológiai és a funkcionalitási összefüggések ismertetésével bemutatjuk saját retrospektív kutatásunkat, amikor angina pectoris miatt végzett koronarográfia során a bal elülső leszálló coronarián kimutatott myocardialis izomhíd morfológiai jellemzőit vizsgáltuk. Összehasonlítottuk a betegek életkilátásait azoknál a betegeknél, akiknél csak myocardialis izomhíd fordult elő, azokkal, akiknél szignifikáns arteriosclerosis is jelen volt.Eredmények:Az intravascularis ultrahangvizsgálat alkalmas az eltérés vizualizálására, a kompresszió mértékének megítélésére. Már funkcionális megítélést is lehetővé tesz az intracoronariás Doppler- és a frakcionális ’flow’ rezerv vizsgálat. A nem invazív funkcionális vizsgálatok közül a leggyakrabban a terheléses echokardiográfia használatos. Saját eredményeink szerint, ahol koronarográfiával izolált myocardialis izomhidat találtunk, ott a csoport morfológiai jegyei súlyosabb jellemzőket mutattak, a myocardialis izomhíd rövidülése nagyobb volt. A hosszú távú, 10 éves utánkövetés során a mortalitás kicsi volt, és eredményeink azt mutatták, hogy a mért morfológiai paraméterek egyike sem befolyásolja a mortalitást.Következtetés:Alapvető ellentmondás az állapot gyakori előfordulása a jó prognózisa, illetve a nagyszámú esetleírás között, ahol súlyos szövődményeket mutatnak be.

Authors: Amin Mohammad Nurul
Published: April 2023

The present study was conducted to assess the cytotoxicity, thrombolytic, anthelmintic and antioxidant activity of mehanolic extract of Litsea monopetala (Family: Lauraceae) leaves in laboratory using in vitro methods. Cytotoxicity test was done by brine shrimp lethality bioassay where the extract concentration was 400, 200, 100, 50, 25, 12.5, 6.25, 3.125, 1.5625, 0.78125 (µg/ml). In vitro thrombolytic activity of Litsea monopetala was performed by clot lysis method using extract concentration 2.5, 5, 10 and 20 (mg/mL) in saline water. Anthelmintic activity test was done by using adult earthworms where 10, 20, 40, 60, 80 (mg/ml) extract concentration were used. Finally antioxidant activity was determined by total phenolic content determination using Folin-Ciocalteu reagent. The Litsea monopetala extract showed cytotoxic activity against brine shrimp nauplii and LC50 value was 41.05(µg/ml) and the investigated thrombolytic activity in our research was 9.52, 9.49, 13.64 and 17.50 %   respectively as % of clot lysis. The paralysis time were at 76.75 min, 60 min, 51.75 min, 44.5 min and 64.5 min and death were at 90.50min, 63.75min, 55.50min, 44.75min and 71min. respectively. The Litsea monopetala extract displayed significant antioxidant activity which was 20.75 (mg of GAE / gm) of extracts. The activities observed could be attributed to presence of some of the phytochemicals which have been related with cytotoxic, thrombolytic, anthelmintic and antioxidant property.

Geomatic tools could be used efficiently for urban development planning. The problem of the study lies in the extensive land use of terrains that are now suitable for heavy construction which slows down the development of new facilities. Furthermore, the authorities are forced to plan future settlements around Setif, at a distance of 8 to 12 kilometers from the city limits, threatening the long-term viability of construction and the ring of farmland that connects them to the core city. This must be done during the planning stage based on a diachronic analysis of all the natural and physical factors/parameters. The main objective of this research is to explore the application of landscape metrics to the analysis and monitoring of urban growth in the city of Setif, north-east of Algeria. For this purpose, our research paper uses Geographic Information System (GIS) and Remote Sensing (RS) techniques based on Principal Component Analysis (PCA) and the Angle Mapper Algorithm (SAM) target method for the analysis of urban land planning and sustainable urban planning of Setif. In the result of these analyses we propose suitability/buildability maps with more suitable construction sites. The research method is based on a 17-year time series dataset compiled from the Sentinel 2A and Landsat imagery between 2004 and 2021. Additionally, we used a cadastral Vs geotechnical overlay to estimate soil capacity. This work proves again that the integration of RS and GIS techniques allows for scientific identification of the lands suitable for urban development (LAUP).

Zearalenone (ZEA) exposure has carcinogenic effects on human and animal health by exhibiting intestinal, hepatic, and renal toxicity. At present, the un-derlying mechanisms on how ZEA induces apoptosis and damage to tissues still remain unclear. In this study, we aimed to identify genes that modulate the cellular response to ZEA using clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 screening, and further validate novel gene functions to elucidate molecular mechanisms underlying particular biological processes in vivo and in vitro. Two ZEA-resistant cell lines, designated Ov-KCNJ4 and Ov-KCNJ12, were yielded by CRISPR activation screening which had significant changes in ZEA resistance and growth rates. Results showed that ZEA could interact with the cell membrane proteins KCNJ4 and KCNJ12, inducing cell cycle arrest, disruption of DNA replication and base excision repair. Overexpression of KCNJ4 and KCNJ12 was involved in ZEA resistance by regulating cell cycle to neutralize toxicity, sustaining mitochondrial morphology and function via at-tenuating the damage from oxidative stress in the KCNJ4-mitoKATP pathway. In vivo experiments showed that AAV-KCNJ4 delivery significantly improved ZEA-induced renal impairment and increased antioxidative enzyme activity by im-proving mitochondrial function. Our findings suggest that increasing potassium channel levels may be a putative therapeutic target for mycotoxin-induced damage.
Fanatyzm jako problem wychowawczy

Education is such an introduction into values thanks to which they become a constant point of reference in action, and in this way the habit of referring to the norms indicated by these values and their application is perpetuated. However, unconditional, ruthless and passionate compliance with the norms is a symptom of fanaticism. Referring to two philosophical concepts, the article is an attempt to answer the question of how to educate people to opt for the values while avoiding shaping a fanatical attitude in the educated person. The approach of L. Kołakowski and R. Rorty, emphasizing the principle of inconsistency, and the approach of A. MacIntyre pointing to the virtue ethics are analyzed.

Published: April 2023

The aim of the article is to show the potential of theatrical art in intercultural education, and more specifically in the process of taming the broadly understood Otherness. The first part of the study presents the conceptual categories: the Other and the Stranger in the perspective of intercultural education. The intercultural intentions of art are also characterized, with particular focus on theatre and emphasizing the role of theatre activities in developing attitudes of tolerance towards cultural diversity. The most important features of theatre allowing for the recognition of theatre as an effective and attractive tool for intercultural education were indicated. The second part of the study is related to educational practice, as it is a record of an original theatre project addressed to primary school students, aimed at sensitizing to cultural differences. As part of the project, a spectacle dealing with the issues of various dimensions of Strangeness / Otherness (biological, economic, cultural, geophysical, mental) was realized, emphasizing their relativity and contextuality. There were also theatrical and intercultural workshops referring to the performance and to developing the attitude of tolerance with the use of such theatrical techniques as: movement games, drama, theatre improvisation, voice games with theatrical intention.

Resumo Este trabalho analisa, sob a ótica das propriedades desejáveis das curvas de juros, a adequação à realidade brasileira das Estruturas a Termo das Taxas de Juros fixadas pela Susep para fins de avaliação dos passivos atuariais e de determinação do requerimento de capital adicional baseado no risco de mercado. Com o intuito de analisar a aderência das curvas aos dados observados, foram calculados os erros de estimação, suas estatísticas descritivas e a média dos erros quadráticos médios. Para analisar a volatilidade das taxas estimadas, definiram-se prazos de interesse e apurou-se, para cada prazo, o desvio-padrão ao longo do período de análise. Os resultados encontrados indicam que as curvas fixadas apresentam, em geral, aderência satisfatória aos pontos observados no mercado. Não obstante, há evidências de que as taxas de longo prazo estimadas pelas curvas construídas pela Susep possuem volatilidade mais elevada do que a verificada para as taxas de longo prazo observadas, o que se configura uma questão relevante de ordem prática. Por fim, as curvas prefixada e cupom de IPCA da Susep foram comparadas às da Anbima e estas últimas se mostraram mais eficazes, justificando a decisão da Susep de parar de gerar algumas de suas curvas.
