Published: August 2021

Background and Study Aim. The aim of the research is to investigate the efficiency of designed complexes of training exercises aimed to improve the coordination abilities of qualified athletes in fencing.
Material and Methods. 22 qualified athletes specializing in fencing aged from 15 to 18 took part in the research. The study design included the sequential pedagogical experiment that was realized through the several stages.  At the first stage, the preliminary testing of the athletes’ coordination abilities (n=22) was conducted. During the preliminary testing the following tests were applied: jumps to the line; shuttle run (4x9 m.); T-test, straight touch from en-garde position to the target of 10 cm in diameter from close range (10 attempts); straight lunge attack from en-garde position to the target of 10 cm (10 attempts). At the second stage of the pedagogical experiment two complexes of exercises aimed at developing the coordination abilities of the athletes were applied for 3 months. The experimental complexes of exercises were used twice a week. At the third stage, the efficiency of experimental complexes aimed at the developing of coordination abilities of qualified athletes in fencing was checked through a control testing. The Statistica 10 software created by the StatSoft Company was used for statistical processing of data.
Results. It was established that during the process of coordination abilities development, the greatest attention should be given to the athletes’ ability to control timing, spatial and physical parameters of moves and moves consistency. To improve the process of developing the coordination abilities of the qualified athletes in fencing two complexes of training exercises were developed. The results of the pedagogical experiment confirmed the statistical differences in the levels of the athletes’ coordination abilities manifestation before and after using experimental training complexes (p<0.05).
Conclusions. It has been shown that specially developed training complexes could be used during the training process in order to develop and increase the level of coordination abilities of qualified athletes in fencing. The analysis of experts’ opinion showed that the development of coordination abilities in fencing should be oriented towards the development of athletes’ ability to control timing, spatial and physical parameters of movements.

Authors: Aksay Ebubekir
Published: August 2021

Background and Study Aim. It was aimed to measure the effects of single-leg stance on measuring the individual postural limits and balance skills of elderly adults.

Material and Methods. The present study involved a total of 360 elderly adults aged between 70 and 80 years. The participants were divided into two groups as 187 individuals in experiment group (99 women / 88 men) and 173 individuals in control (94 women / 79 men). In measuring the risk of fall and balance skills, the Functional Reach Test, Timed up and go Test, and Single Leg Stance Test were used. The participants in experiment group were asked to stand on one foot for a total of 4 minutes (2 minutes in morning and 2 minutes in evening) every day while brushing their teeth for 50 weeks. Since the data showed normal distribution, the independent samples t-test was used in determining the intergroup difference, whereas the dependent sample t-test was used in determining the intragroup pretest-posttest difference.

Results. It was determined that there was a significant relationship between elderly adults’ balance skills and 4-min/day single-leg stance practice (p<0.05). In all the tests, it was found that the balance skills of women and men have improved and men had better values in comparison to women.

Conclusion. It is thought that, via simple procedures such as lifting up one foot while brushing the teeth, the balance skills of elderly adults can be improved, the risk of fall can be reduced. They can be supported in terms of living an independent life.
Correlation of maximal respiratory exchange ratio with anaerobic power and maximal oxygen uptake in anaerobic trained athletes
Authors: Korkmaz Eryılmaz Selcen , Polat Metin
Published: August 2021

Background and Study Aim. The respiratory exchange ratio (RER) is the ratio of the amount of carbon dioxide produced (VCO2) to the amount of oxygen uptake (VO2) is important. It indirectly informs about the predominant metabolic pathway to provide the energy needed during exercise. The relationship of maximal RER with aerobic and anaerobic capacity in athletes remains unclear. The purpose of this study was to investigate the relationship between maximal RER and anaerobic power and maximal oxygen uptake (VO2max) in anaerobic trained athletes.
Material and Methods. Thirteen male alpine skiers (age 18.1 ± 3.1 years) competing in national and international competitions participated in the study. Athletes first performed an incremental treadmill run test to determine their VO2max (ml/kg/min), maximal RER (VCO2 / VO2) and maximal running speed (km/h). After 48 hours, the athletes performed the Wingate anaerobic test to determine peak power, mean power, minimum power, and fatigue index. Pearson correlation coefficients were used to examine the relations between variables.
Results. Maximal RER was positively correlated with peak power (r = 0.587, p < 0.035), mean power (r = 0.656, p < 0.015) and minimum power (r = 0.674, p < 0.012). Maximal RER did not significantly correlate with fatigue index (p > 0.05). Maximal RER was negatively correlated with the VO2max (r = – 0.705, p < 0.007) and maximal running speed (r = – 0.687, p < 0.01).
Conclusions. Maximal RER may be useful for evaluating anaerobic capacity in anaerobic-trained athletes. Measuring the maximal RER values of athletes during incremental exercise may provide information about physiological adaptations in response to physical training.

One of the most common conditions resulting from micronutrient deficiency is iodine deficiency. Purpose — to evaluate the current state of iodine supply in schoolchildren living in the North-Eastern region of Ukraine, including children with digestive diseases and inflammatory joint diseases. Materials and methods. Target group: 86 people (11.8±2.71 years), which included patients with digestive diseases (DD) (26.7%) and juvenile idiopathic arthritis (JIA) (60.5%). Methods: dietary iodine intake evaluation by urinary iodine concentration (Sandell–Kolthoff reaction), followed by calculation of the median. Results. Median urinary iodine excretion was at the lower normal range and amounted to 104.98 μg/l [QR: 59.8; 180.1] in the examined children. Only 51.2% of children had adequate iodine provision; mild iodine deficiency (ID) was diagnosed in 29.1% (Ме=81,91μg/l [QR: 64.26; 90.58]); moderate — 17.4% (Ме=36,19 μg/l [QR: 33.54; 42.24]); severe — in 2.3% of the surveyed (Ме 14,02 μg/l [QR: 12.34; 15.70]). The median urinary iodine excretion in children with somatic diseases was significantly lower than in children of the control group and amounted to 97.26 μg/l [QR 53.7; 148.3] versus 183.71 μg/l [QR 104.4; 287.4], (p=0.003). Conclusions. School-age children have a high incidence of iodine deficiency (51.2%). Often encountered in childhood diseases (DD and JIA) are accompanied by insufficiency of iodine supply. The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local Ethics Committee of all participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the author.

The close anatomical and physiological connection of the digestive organs leads to a significant spread of functional disorders in various diseases. Purpose — to investigate the frequency and features of the clinical course of biliary dysfunction (BD) in children. Materials and methods. 66 children aged 10–18 years with BD were examined. The study included a complete clinical examination of children, laboratory and instrumental methods. To assess the severity of clinical symptoms in the examined patients was used traditional score scale of symptoms (0–3 points) and the frequency index (FI). Results. In most children, the database was combined with other functional and organic lesions of the digestive tract (n=56, 84.8%). The database was most often combined with chronic gastritis and duodenitis, as well as with functional motor disorders. FI in children with BD involved in the pathological process of the stomach and duodenum was the highest (0.59), and IR in children with BD and intestinal involvement was the lowest (0.23). The relationship between the frequency of combined pathology and the frequency of cases of increase in the size of the gallbladder (χ2=22.87 at a critical value of χ2=9.33 for the significance level p<0.01). Hyper- or hypofunctions of the biliary tract occurred with the same frequency. Conclusions. Biliary dysfunction in children is significantly more often combined with chronic gastritis and duodenitis, as well as with other functional disorders of the gastrointestinal tract (duodenogastric reflux). In children with biliary dysfunction and involvement in the pathological process of other parts of the gastrointestinal tract there is an increase in the frequency of exacerbations, more pronounced signs of dyspeptic syndrome on the background of pain with the same intensity and more often ultrasound reveals signs of gallbladder dysformation. The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local Ethics Committee of all participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: children, biliary dysfunction.

The article presents current data on the prevalence of vitamin D deficiency and criteria for its deficiency in children in different countries. Vitamin D is recognized as one of the most important vitamins involved in many biochemical processes in the body. Its active metabolites play a key role in calcium absorption, bone mineralization and promote phosphate and magnesium metabolism. At the same time, in addition to affecting mineral metabolism, there is a wide range of conditions in which vitamin D also plays a preventive role. Vitamin D has been shown to play a vital role in innate immunity maintenance and is important in prevention of several diseases, including infections, autoimmune diseases, certain forms of cancer, type 1 and 2 diabetes, and cardiovascular diseases. Vitamin D is of particular importance for newborns and young children. This vitamin is involved in important physiological regulatory processes such as bone metabolism, lung development, maturation of the immune system and differentiation of the nervous system. Vitamin D deficiency increases risks of neonatal sepsis, necrotizing enterocolitis, respiratory distress syndrome, and bronchopulmonary dysplasia. Adequate intake of vitamin D and calcium during childhood can reduce the risk of osteoporosis and other diseases associated with vitamin D deficiency in adults. Recently, vitamin D deficiency has shown to be a potential risk factor for COVID-19 propensity. It has been established that to date most scientific pediatric societies have recognized the need to prevent vitamin D deficiency in healthy children of all ages, but data on the dosage of vitamin D in its prophylactic use differ. Most scientific societies recommend an average of 400–600 IU per day of vitamin D for prophylactic purposes. The analysis of published data shows the need to follow a strategy based on an individual approach, taking into account physiological characteristics, individual requirements and lifestyle.

The multifactorial nature of subacute cough, combined with the anatomical and physiological characteristics of preschool children, the impossibility of their full examination in outpatient practice, complicates its diagnosis. An algorithm for the differential diagnosis of acute respiratory infections accompanied by subacute cough in preschool children has been developed, it can contribute to the early identification of its causes and targeted treatment of the disease that caused the cough. A sequence of diagnostic measures is proposed, it includes anamnesis of life and diseases with a list of key questions that should be asked when collecting anamnesis in children with prolonged cough; objective examination of the child; determination of the tactics of further management (inpatient or outpatient); the choice of therapy that is comparable to the intended diagnosis; and evaluation of ongoing therapy. The emphasis is made on the importance of a full-fledged collection of anamnesis, taking into account the data of the time and conditions of the disease, and clinical data for making a presumptive diagnosis in an outpatient practice. It is recommended to carry out trial therapy if the diagnosis is difficult. The article presents modern approaches to the diagnosis of bronchial asthma in children with recurrent virus-induced vising. The modern approaches to the diagnosis and treatment of acute respiratory infections of the upper and lower respiratory tract are outlined in accordance with the principles of evidence-based medicine. It is noted that the most effective methods of treating cough are etiological and pathogenetic approaches, which consist in eliminating or weakening the action of factors that cause cough. It is emphasized that if treatment is impossible or insufficient, symptomatic cough therapy should be carried out. The main directions of symptomatic treatment of cough have been substantiated, which include measures to improve the drainage function of the lungs and restore adequate mucociliary clearance. The expediency of using ambroxol and acetylcysteine preparations was confirmed. Attention is also paid to the use of centrally acting antitussives. Discussion of the problem «to treat or not to treat subacute cough in acute respiratory infection of the upper respiratory tract» from the standpoint of evidence-based medicine is shown.

Purpose — to discover peculiarities of Wilson disease course in children dependently on the variant of liver affection. Materials and methods. Anamnesis of the disease and clinical and paraclinical peculiarities of the course of the disease with consideration of liver affection severity have been studied in 50 children aged 5–17 years. Results. It was estimated that in 52% of children the disease had a form of chronic hepatitis with minimal clinical symptoms, 44% of patients had liver cirrhosis with predominant signs of edematous and ascitic syndrome and 4% had fulminant hepatitis in a debut of the disease. Complicated family anamnesis was detected in 4% of patients. Syndrome of cytolysis predominated in patients with liver damage in the form of chronic hepatitis (р<0.05). Typical biochemical changes in cirrhotic patients were hepatocellular insufficiency with hypoalbuminemia and coagulopathy, hyperbilirubinemia and minimal hypertransaminasemia (р<0.05). Children with cirrhosis in contrast to patients with chronic hepatitis had reliably lower serum ceruloplasmin concentration and reliably higher excretion of copper with urine. Specific for Wilson disease Kayser—Fleischer rings were found out in 36% of patients only. Conclusions. Wilson's disease in children is characterized by progressing course in the form of either chronic hepatitis or liver cirrhosis or, rarely, fulminant hepatitis. Clinical and paraclinical symptoms of the disease are estimated by the severity of liver affection and vary from a course with minimal symptoms in patients with chronic hepatitis to edematous and ascitic syndrome and hepatocellular insufficiency in patients with cirrhosis and fulminant hepatitis. The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local Ethics Committee of all participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors.

This paper presents the variations of the rate of change of Total Electron Content (TEC) index (ROTI), characterizing the occurrence of ionospheric plasma irregularities over Vietnam and neighboring countries in the Southeast Asian region using the continuous GPS data during the 2008-2018 period. The results showed that the occurrence of strong ROTI in all stations is maximum in equinox months March/April and September/October and depends on solar activity. The ROTI is weak during periods of low solar activity and strong during periods of high solar activity. There is an asymmetry between the two equinoxes. During maximum and declining phases of 2014-2016, occurrence rates in March equinox are larger than in September equinox, but during the descending period of 2010-2011, the occurrence rates in September equinox at almost all stations are larger than in March equinox. The correlation coefficients between the monthly occurrence rate of irregularities and the F10.7 solar index at the stations in the equatorward EIA crest region are higher than at those in the magnetic equatorial and the poleward EIA crest regions. The irregularity occurrence is high in the pre-midnight sector, maximum between 2000 LT to 2200 LT. The maximum irregularity occurrence is located around 4-5° degrees in latitude equator-ward away from the anomaly crests.
Reflections about abortion limitation

Published: August 2021

Abstract The debate on abortion has not yet found a clear solution. In fact, there is still discussion about what the limits of this procedure should be. This uncertainty is related to the lack of a clear definition of human life: when can the product of conception be defined as a human being with full medical-legal rights? Based on the answer to this question, the various world governments have drafted more or less restrictive laws regulating abortion. Since May 2019, some American states have considerably restricted the possibility of carrying out abortion on their territory. Alabama has practically banned abortion in any circumstance (including incest and rape). Obviously, these restrictive policies have had a significant impact on the social, bioethical and legal debate, concerning abortion, globally. This paper analyses the implications of these policies with a focus on women’s fundamental rights: the right to health and the right to self-determination.

Resumo O objetivo deste artigo é descrever a associação entre variação de IMC, padrões alimentares e atividade física entre adultos de 21 a 44 anos no período de 2007 a 2012. Estudo transversal com a base de dados do VIGITEL. Padrões alimentares foram identificados com Análise de Principais Componentes para o período de 2007 a 2012. Componentes com autovalores >1,0 foram retidos e cargas fatoriais superiores a |0,3| foram destacadas. Para cada indivíduo, um escore foi calculado por padrão. Em seguida foi criada variável de diferença do Índice de Massa Corporal (ΔIMC). Regressão linear com desfecho ΔIMC e regressão de Poisson com desfecho obesidade foram conduzidas. Quatro padrões alimentares foram retidos: Prudente, Transição, Ocidental e Tradicional. Após ajuste multivariável, ΔIMC mostrou-se inversamente associada à prática de atividade física no lazer. Obesidade apresentou associação positiva com padrão Ocidental, assistir à televisão ≥3 horas por dia e inatividade física. Obesidade mostrou-se inversamente associada com padrão Prudente, padrão Tradicional, prática de atividade física no lazer e prática de atividade física no trabalho. Padrões alimentares baseados em alimentos in natura e minimamente processados e prática de atividade física constituem fatores de proteção para a obesidade.

Resumo O artigo analisa a estrutura e o desempenho das assistências médica e odontológica de duas regiões, distintas socioeconomicamente e na oferta de serviços, por meio de estudo de caso nas regiões Norte-Barretos (São Paulo) e Juazeiro (Bahia) entre 2007-2014, a partir das dimensões política, organizacional e estrutural e de indicadores de estrutura e desempenho. Observou-se que a regionalização foi reconhecida de forma positiva, a distribuição dos serviços não atendia à demanda populacional e a capacidade instalada da rede de atenção à saúde não estava adequada às necessidades da população. Norte-Barretos se sobressaiu em relação à estrutura (exceto para cobertura potencial da ESB na ESF) e efetividade; enquanto Juazeiro se destacou em relação à eficiência; embora com menos recursos, a utilização dos serviços foi relativamente mais elevada. O padrão observado parece refletir aspectos relacionados à re gionalização e à trajetória política de cada assistência, o efeito silos. Os resultados podem subsidiar o desenho de políticas de saúde voltadas a superar o subdimensionamento da estrutura de serviços públicos assistenciais nas regiões de menor desenvolvimento socioeconômico e a busca de parâmetros e mecanismos de coordenação a fim de equilibrar indicadores de desempenho.

Resumo Este artigo aborda a relação entre a obrigatoriedade de dispositivos de retenção (cadeirinhas) e as internações e mortes de crianças de zero a quatro anos em sinistros de trânsito no Brasil. A partir da obrigatoriedade do uso de dispositivos de retenção para crianças de até quatro anos pela legislação de trânsito brasileira, ocorrida no ano de 2010, os autores utilizam os dados do sistema DataSUS e do Denatran para analisar as séries temporais das internações e mortes de crianças de zero a quatro anos em sinistros de trânsito ocorridas no período de setembro de 2005 a agosto de 2015. São realizados dois recortes. Primeiro, uma análise do período compreendido entre os anos de 2005 e 2015, posteriormente esse período foi dividido em duas amostras, antes e depois da obrigatoriedade. Os resultados em ambos os recortes sugerem que a exigência da utilização dos dispositivos de retenção gerou redução de internações e mortes de crianças por sinistros de trânsito na faixa etária de zero a quatro anos, com prevalência da redução de internações sobre a de mortes.

Resumo A análise espacial da sífilis constitui-se numa ferramenta capaz de contribuir no estabelecimento de diretrizes de atuação nas áreas geográficas prioritárias para intervenções preventivas. O objetivo do artigo foi descrever as evidências produzidas pelos estudos que utilizaram a análise espacial para identificação das áreas prioritárias de intervenção para sífilis. Trata-se de uma revisão integrativa da literatura, realizada nas bases de dados Medline/PubMed, Scopus, Web of science, Lilacs, Ibecs, Portal da Biblioteca Cochrane, SciELO, Cuiden e Bdenf através do cruzamento entre os descritores “sífilis”, “análise espacial”, “sistema de informação geográfica”, “educação em saúde” e “mapeamento geográfico”. Foram analisados 13 artigos e na maioria deles os casos de sífilis se apresentaram distribuídos de forma heterogênea, não obedecendo um perfil epidemiológico único em relação as unidades de análise. Foi demonstrado efeito ecológico e espacial discordante entre sífilis e o HIV e a viabilidade no rastreio integrado da sífilis com outras doenças. Foi evidenciado eficácia e capacidade da análise espacial em direcionar intervencões educativas específicas para cada realidade evitando o investimento em áreas geograficamente não prioritárias para o controle da sífilis.

Resumo Estudo de prevalência realizado com pessoas vivendo com HIV/Aids, em terapia antirretroviral, com o objetivo de comparar a qualidade de vida e a insegurança alimentar entre homens e mulheres. Foram incluídos aleatoriamente quatrocentos e oitenta e um indivíduos que buscaram atendimento hospitalar. A insegurança alimentar foi avaliada pela Escala Brasileira de Insegurança Alimentar e a qualidade de vida pelo instrumento WHOQOL-HIV-Bref. Os resultados foram apresentados em frequência absoluta e relativa e as diferenças entre os sexos foram testadas com o teste qui-quadrado, considerando significância de 5%. Do total da amostra, 40,1% eram do sexo feminino e essas apresentaram piores condições de renda (65,8%), baixa escolaridade (72,5%), menor prevalência de segurança alimentar (29,02%) e qualidade de vida abaixo da média (54,9%), comparadas com os homens (44,4%). Os resultados do estudo mostram que além das dificuldades enfrentadas pelos portadores do vírus HIV, este grupo apresenta uma importante desigualdade de gênero e a gestão do cuidado voltado a estas pessoas deve considerar este importante achado, promovendo o acesso a políticas sociais e promovendo a isonomia entre os gêneros, em prol de uma vida feminina mais justa e igualitária.

Resumo O objetivo do estudo foi avaliar o risco de infecção por HIV em homens que fazem sexo com homens (HSH) a partir do desenvolvimento de um índice que considere as redes de parceiros sexuais. As variáveis do índice foram faixa etária, raça/cor, escolaridade, tipo de relacionamento, uso de preservativo em relações receptivas e insertivas, autopercepção da chance de se infectar pelo HIV, história de infecções sexualmente transmissíveis, além dos resultados dos testes rápidos para HIV. Foram utilizados dados de uma pesquisa de rede egocêntricas HSH, com desenho transversal, realizada no Rio de Janeiro entre 2014 e 2015. O voluntário inicial da pesquisa é denominado ego, cada parceiro é alter, e cada par de pessoas em um relacionamento é a díade. Utilizou-se regressão logística múltipla para definição dos coeficientes das equações para elaboração dos índices. O índice variou de 0 a 1, quanto mais próximo de 1, maior o risco de infecção por HIV. A prevalência de HIV dos egos foi de 13,9%. A média do índice dos egos com teste HIV reagente foi 57% maior do que aqueles não reagentes, o mesmo perfil foi observado nos valores dos índices das díades. O índice permitiu incorporar os dados das redes por meio das díades e contribuiu para a identificação de indivíduos com maior chance de aquisição do HIV.

Method: a cross-sectional study, with non-probabilistic sampling. Data was collected between July 2018 and February 2019 in two high-complexity hospitals, and the sample was composed of 304 participants. The validity analysis of the Work Limitations Questionnaire was performed by means of Confirmatory Factor Analysis. Results: most of the participants were women (88.5%), with a mean age of 40.9 years old. The validities of the factorial, convergent and discriminant construct and the reliability of the complete version and of the 16-item version of the instrument were adequate after adjusting the models to the sample. A statistically significant and negative correlation (p<0.001) was verified between the workload, working time and the Time Management and Physical Demands dimensions; as well as a statistically significant (p<0.001) correlation between working time and the Mental-Interpersonal Demands and Production Demands dimensions. Gender and professional category did not influence presenteeism. The rate of loss of productivity at work was 19.51%. Conclusion: the Work Limitations Questionnaire showed adequate validity and reliability and can be considered a valid and reliable instrument for assessing presenteeism in the nursing team.

Abstract: Introduction: The Covid-19 pandemic interrupted and challenged the traditional structure of medical education, based on face-to-face teaching, and, as a measure of support for the efforts of government agencies to reduce the risk of spreading the disease, distance became necessary. medical/patient care and the increase in the supply of telehealth services by health systems. In Brazil, the telehealth model seeks to improve the quality of care in primary health care (PHC), integrating education and service through tele-education and tele-assistance activities, such as teleconsulting, the Second Formative Opinion (SOF), tele-education and telediagnosis. Thus, this article reports the experience of medical students in telehealth actions during the Covid-19 pandemic in Brazil, seeking to clarify the contributions and limitations of this experience in the teaching-learning process in the context of medical education. Experience report: Participation in the project allowed the experience of various telehealth activities under the supervision and guidance of professors in the health area, in addition to the production of informative and educational materials. The proposed activities allowed for the improvement of clinical reasoning through evidence-based medicine (EBM), especially in helping teleconsultations and frequently asked questions. Discussion: The use of technologies became indispensable during the pandemic, and, within this scenario, a telehealth project proved to be an important and effective strategy for continuing education among professionals and health education for the community, avoiding crowding and preventing the spread of the virus. In addition, remote actions, such as teleconsultations, resolution of frequently asked questions and tele-education, proved to be an important strategy for accessing health care not only in times of pandemic. Conclusion: Our experience made it possible to foster critical thinking and disseminate content in a safe, technical and evidence-based way. The exercise of clinical reasoning led us to an experience of great value and to believe that the inclusion of the practice of telehealth can bring important gains to the curriculum of Medicine courses.

RESUMO: Ao longo desse estudo são apresentados argumentos para a ideia de motivação de aprendizado de Física. As discussões no contexto de ensino superior nessa área conduzem ao seguinte questionamento: a motivação é algo que o estudante já deve trazer consigo ou é uma qualidade que ele desenvolve durante o curso? A partir dessa questão, o presente ensaio busca discutir as ideias acerca da natureza da motivação humana como subsídio para a atividade educativa do professor. A discussão se fundamenta nos estudos sobre a atividade humana, defendendo que a motivação para o conhecimento científico deve ser desenvolvida desde os níveis escolares mais básicos. O estudo aprofunda o significado de motivo, por meio da análise de conceitos baseada em princípios, concluindo que existem motivações distintas entre jovens do Ensino Médio e acadêmicos do Ensino Superior de Física, indicando a necessidade de Formação Docente e Iniciação Científica para essa transição educacional.

Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are among the most important and most widely used materials of coherent and nonlinear optics, as well as acoustics. High degree of uniformity and reproducibility has become the foundation of technology for manufacturing high-quality crystals, absorbed by many suppliers around the world. However, the above areas do not limit the use of LiNbO3and LiTaO3due to their unique piezoelectric and ferroelectric properties. One promising application of crystals is the design of electromechanical transducers for precision sensors and actuators. In this respect, the high thermal stability of the piezoelectric and mechanical properties, the lack of hysteresis and creep make it possible to create electromechanical converters with wide operating temperature range, that is beyond the capability of commonly used ferroelectric ceramics. The main advantage of LiNbO3and LiTaO3over other single-crystal piezoelectrics is ferroelectric domain structure regulation toward targeted impact on the device characteristics. One of the most striking examples of electromechanical transducer design through domain engineering is the formation of a so-called bidomain ferroelectric structure in crystal. It represents a single-crystalline plate with two macrodomains with opposite directions of spontaneous polarization vectors separated by a charged domain wall. High switching fields make inversion domains stable at temperatures up to 1000 °C. This review summarizes the main achievements in the formation of bidomain structure and near surface inversion domains in LiNbO3and LiTaO3crystals. We present the domain structure virtualization methods in crystals and non-destructive methods for controlling the domain boundary position. The report contains a comparative analysis of the methods for forming inversion domains in crystals, and the patterns and technological control methods of the domain structure are discussed. The basic physical models have been proposed in the literature to explain the effect of the inversion domains formation. In the present paper we outline what one sees as strengths and weaknesses of these models. The strategies of crystallographic cut selection to create devices based on bidomain crystals are briefly discussed. We provide examples of the implementation of devices based on bidomain crystals such as actuators, sensors, acoustic transducers, and waste energy collection systems.
Electrical conductivity of YBa2Cu3O7-δ single crystals under conditions of anionic ordering in Cu(1)O1-δ layers
Authors: Kalanda N. A.
Published: August 2021

The influence of thermocycling annealing processes on the oxygen ordering degree (order parameter) in theYBa2Cu3O7-δ single crystals have been studied. It was determined that an increase in the critical temperature of the onset of the transition to the superconducting state during step annealing procedures is consistent with decrease of the σс/σаb parameter. This fact indicates the redistribution of the electronic density between the Cu(2)O2 and Cu(1)O1-d structurally-inhomogeneous planes, due to the formation of the oxygen long-range ordering in the O(4)—Cu(1)—O(4) linear groups along the (b) crystal structure axis of the unit cell, and removal of the oxygen defects in the square nets of the Cu(2)O2 planes. The existence of a critical value of the conductivity anisotropy σс/σаb, below which its behavior does not correlate with the change of Тс, has been proved. In this case, the increase of Тс and the orthorhombic distortion of the crystal structure at the isothermal annealing processes occur due to the amplification of the «interlayer» interaction between the Cu(2)О2 and Cu(1)О1-δ planes. As a result, the contribution of the Cu(1)О1-δ chain layers in the electronstate density on the Fermi level increases. These layers could be the superconducting ones by means of the Cooper pairs tunneling from the Cu(2)О2 planes, forming the induced superconductivity there.
