DAS FISSURAS ENTRE SER E DEVER SER: AUTORREFLEXÕES DE UMA PROFESSORA DE EDUCAÇÃO FÍSICA
Authors: ALBINO BEATRIZ STAIMBACH
Published: May 2023

RESUMO: Desde os anos 80, há certo fascínio pelo tema do professor reflexivo/pesquisador. Pouco se diz, contudo, que essa discussão é parte de uma com escopo maior, de crítica ao positivismo e à racionalidade. Seguindo a tradição da Teoria Crítica da Sociedade, discorreu-se sobre alguns pressupostos teóricos-metodológicos para então refletir sobre a prática docente e a conjuntura escolar em que esta autora se insere. A violência e a indiferença como inerentes ao processo civilizador de que a Educação faz parte, e o enfrentamento das contradições entre ser e “deve ser” docente como um antídoto à reprodução da barbárie, aparecem como temas centrais. Fez-se uso de registros e memórias do período de iniciação à docência e inserção no ambiente de trabalho (anos de 2019 e 2020), com atenção ao meu fazer docente e um “dever ser professora” latente no cotidiano escolar, em suas interconexões com aspectos sociais e culturais. No trabalho de elaboração (cognitiva e afetiva) da experiência, a pouca racionalidade imperante no espaço escolar foi um dos pontos chave da análise, se revelando, entre outros: na insistência na retórica e nos postulados educacionais, ao preço de negação da realidade; na predominância do princípio da concorrência, sobretudo entre pares e com singularidades que remetem a questões de gênero; e na dificuldade de se enfrentar a violência nas aulas de educação física. Encerra-se com alguns apontamentos sobre autorreflexão docente, especialmente a urgência de que nesse processo o princípio ético-político se sobreponha a objetivos meramente instrumentais/performáticos.
FORMAÇÃO E DOCÊNCIA COMO PHRONESIS: SENDO E APRENDENDO A SER
Authors: KRONBAUER LUIZ GILBERTO , FENSTERSEIFER PAULO EVALDO
Published: May 2023

Resumo: Inspirados na noção aristotélica de Phronesis, desenvolveu-se uma reflexão sobre a formação docente na perspectiva do aprender como exercício que se faz e se refaz continuamente, numa atitude reflexiva e, teoricamente, sustentada. Aproximou-se o conceito de vida contemplativa ao de docente reflexivo e, com isso, buscou-se avançar na direção da práxis como processo dialético de ação-reflexão-ação, pano de fundo de uma formação inicial de professores/as que entretece teoria e prática como horizontes de uma docência viva. Esta releitura da filosofia prática de Aristóteles faz-se acompanhar da interpretação que Hans-Georg-Gadamer realiza em sua obra Wahrheit und Methode, valendo-se dos conceitos de sabedoria prática, de mimesis, da produtividade do conceito de experiência e da atualidade hermenêutica de Aristóteles, e que estruturam o texto que segue.
EDUCACIÓN FÍSICA, FEMINIDADES Y UNIFORMES. EL CASO DEL DEPARTAMENTO DE CULTURA FÍSICA (1929-1946) DE LA UNIVERSIDAD NACIONAL DE LA PLATA (ARGENTINA)
Authors: SCHARAGRODSKY PABLO ARIEL , KOPELOVICH PABLO
Published: May 2023

RESUMEN: Indagamos en la construcción de feminidades a partir del uso de uniformes para las clases de Educación Física. Para ello, nos basamos en el caso del Departamento de Cultura Física, institución existente entre 1929 y 1946, de la Universidad Nacional de La Plata (Buenos Aires, Argentina). Nos preguntamos acerca de cómo y por qué los uniformes de Educación Física contribuyeron a generizar y sexualizar los cuerpos de las alumnas. Construimos tres períodos a partir del establecimiento obligatorio de uniformes femeninos para las clases de Gimnasia: 1929-1934, 1935-1939 y 1940-1946. Ese uso se debió a las decisiones tomadas por las autoridades del Colegio Secundario de Señoritas, que implicaron también distintos modos de entender y enseñar la asignatura. Desde una estrategia metodológica cualitativa, proponemos la interpretación de un caso, abordándolo desde las herramientas provenientes de la perspectiva crítica de género y de la historia visual. Utilizamos fuentes escritas y visuales, así como entrevistas semiestructuradas realizadas a ex alumnas. Consideramos que la obligatoriedad de los uniformes, en relación a la construcción de feminidades, involucra dimensiones morales, estéticas, sexuales, materiales, eróticas y kinéticas. En este sentido, Concluimos que lo acontecido con la enseñanza de la Educación Física en el Colegio Secundario de Señoritas, en términos de transmisión de feminidades, da cuenta de una tensión permanente en la sociedad entre igualdad y desigualdad entre las mujeres y los hombres, sin tratarse en absoluto de un recorrido lineal que vaya de la desigualdad a la igualdad, o a menos desigualdad.

Resumo: Temos por objetivo identificar e compreender o processo de desenvolvimento de habilidades Matemáticas durante a invenção de dispositivos robóticos destinados ao tratamento de Parkinson. De acordo com a metodologia qualitativa, os dados foram produzidos com estudantes do Ensino Médio, registrados em vídeos, fotografias, notas de campo, programas computacionais e entrevistas. Tais dados foram analisados à luz dos pressupostos do Construcionismo e organizados em seções que correspondem e tematizam as invenções criadas. Os resultados apontam para o desenvolvimento do raciocínio, argumentação, comunicação, representação e engajamento dos estudantes. Tais habilidades se constituem idiossincraticamente pelas ações e produções intelectuais em um ambiente de formação Matemática que privilegia autonomia e diálogo não hierarquizado e são compreendidas em três dimensões: Técnica, Conceitual e Comportamental. Os dados evidenciam um processo caracterizado pela dinamicidade não linear e orgânica de formação, apontando para o rompimento da tríade conteúdo-exemplo-exercício e das burocracias contraproducentes de sala de aula.
Investigação dos impactos nas concepções não-newtonianas de licenciandos e egressos de Física em relação aos conceitos de Força e Movimento
Authors: Uibson José , Frei Fernando
Published: May 2023

Resumo: Persistem no ensino de Física práticas consideradas tradicionais e que pouco contribuem para a aprendizagem dos alunos. Assim, este artigo teve por objetivo conhecer as concepções não-newtonianas de licenciandos e egressos de um curso de Licenciatura em Física com relação aos conceitos de Força e Movimento, além de analisar possíveis impactos nessas concepções quando os alunos foram expostos a uma Simulação Computacional e a uma apostila, aplicados nas mesmas condições (de forma livre e por curto intervalo de tempo). Trata-se de uma pesquisa quantitativa de delineamento quase-experimental com grupo controle e experimental. Em ambos os grupos foi aplicada uma versão reduzida Force Concept Inventory (FCI) na construção dos dados, tanto no pré-teste quanto no pós-teste. Além das análises das concepções, foi utilizado o ganho normalizado de aprendizagem e o tamanho do efeito. Os resultados indicam que, em média, os tratamentos propostos não influenciaram significativamente as concepções dos alunos.

Published: May 2023

ABSTRACT Objective To identify the food environment healthy eating potential in the authorized food services on the campus of a Brazilian university. Methods This is an observational study carried out between March and April 2014 on a campus of a public university in Rio de Janeiro, Brazil. The elements of the food environment were evaluated using an audit instrument, containing 86 questions: availability (amount of food services and types of food offered), convenience (days and hours of operation), incentives and barriers to healthy eating (nutrition information, payment strategies and food advertisements). Preparations based on whole grains and fresh or minimally processed products were considered healthy foods; and, preparations with high caloric density, sugar-sweetened beverages, sweets, desserts, cookies, and savory snacks were considered unhealthy food. The questionnaire allowed us to calculate a score for each service, which could range from 0 to 36 points, and indicates the potential for promoting healthy eating in the establishment, with higher scores indicating a greater presence of elements that contribute to healthy eating. The different types of food service facilities were compared based on the scores (p<0.05 for statistical significance). Results Among the establishments evaluated, 24% were snack bars/cafeterias, 26%, restaurants, and 50% offered mixed services. Healthy food items were scarcely available in the establishments (fruits: 24%; vegetables: 20%; brown rice: 15%); while added-sugar beverages (98%), sweets and treats (76%) were widely offered. There was a higher frequency of advertising encouraging consumption of unhealthy items than that aimed at healthy foods (44% vs 30%). In general, the score was 13,2 points (SD=3.3) and the mean score for snack bars/cafeterias (9.3 points) was lower (p<0,05) than that of restaurants and mixed establishments (14,4 points). Conclusion On the campus assessed, the food environment had limited potential for healthy eating, since elements that did not favor healthy food choices were more frequent.

Authors: Radicchi Marcelo Rocha
Published: May 2023

ABSTRACT Objective To verify overweight prevalence in the Sateré-Mawé indigenous population over 18 years of age, residing in the city of Parintins (AM), Brazil, and to assess its associated variables. Methods Household survey performed in the urban area of Parintins in 2017, visiting new households in each interview, completing the census universe. Self-declared Sateré-Mawé, over 18 years of age, residing in the city for a period longer than one year were considered eligible. Overweight was considered for body mass index values ≥ 25 kg/m2 or ≥ 27 kg/m2, for those over 60 years of age. Household information on social assistance, as well as individual information such as speaking the indigenous language, years living in the city and also in the indigenous territory, income, work, schooling, marital status, leisure and transport physical activity level, and time watching television per week were retrieved. The hierarchical logistic model analysis was carried out, calculating the odds ratio and confidence interval (95%). Results A total of 174 subjects participated in the survey, 42% being overweight. Those who spoke the Sateré-Mawé language, number of years living in the city, working outside home and being married had a positive effect on the outcome, but lost significance in the final model. Only transport insufficient physical activity (OR=2.24, 95% CI=1.01-4.98) and being in the age group from 30 to 59 years (OR=8.79, 95% CI=3.41-22.64) maintained statistical significance. Conclusion Efforts to provide visibility to the health situation of urban indigenous populations in Brazil are necessary. Poor transport infrastructure in the city seems to favor transport physical activity levels as a necessity, in addition to age, which is commonly associated with overweight.

Abstract Objective To associate clinical parameters of sarcopenia with cognitive impairment in older people. Method Cross-sectional study with 263 older adults (≥60 years) treated at a specialized public health facility. Sociodemographic and clinical variables were used to characterize the sample and the clinical parameters of sarcopenia (muscle strength, muscle mass and physical performance) were assessed based on handgrip strength (HGS), calf circumference (CC) and the Timed Up and Go (TUG) test. The Mini-Mental State Examination (MMSE) was used to evaluate cognitive status. Associations were analyzed by simple and multiple linear and logistic regression considering the clinical parameters of sarcopenia (independent variables) and cognitive status (dependent variable), adjusted for age, sex, years of schooling, number of medications, nutritional status and functional capacity. Results Of participants with cognitive impairment, 59.6% exhibited low muscle strength. Conclusion Low muscle strength was the sarcopenia parameter independently associated with cognitive impairment. This information is useful in highlighting the likelihood of cognitive impairment when poor muscle strength is identified in older people.
EU’s Democractic Conditionality: Democratic Principles and Procedures?
Authors: Monte Déborah Silva do
Published: May 2023

Abstract This article aims at explaining the changes in the democratic conditionality of the European Union over time from the institutional contexts of the domestic and regional levels. The comparison milestones regard enlargements that happened between 1993 and 2014. Variations on the dependent variable are analysed in light of the principles and procedures of the concept of polyarchy (Dahl 1989). This analysis demonstrates and explains that the democratic conditionality of the EU has changed over time, becoming more complete and with more pluralist principles when applied to the enlargements. It also highlights the relation between the democratic conditionality and the democratic deficit of the EU by the incorporation of democratic principles and procedures in EU institutions.
FACILE PRODUCTION OF 4-HYDROXYBENZOIC ACID FROM OIL PALM EMPTY FRUIT BUNCH CELL WALLS BY ALKALI DEGRADATION AT ROOM TEMPERATURE
Authors: Qu Chen , Kawamoto Haruo
Published: May 2023

Oil palm empty fruit bunches are biorefinery waste produced from the oil palm factory. Palm lignin is
partially ended with p-hydroxybenzoylated structure, which is a promising resource to produce 4-hydroxybenzoic
acid. Herein, 4-hydroxybenzoic acid is produced by the degradation of oil palm empty fruit bunch cell walls with sodium hydroxide solution at room temperature without lignin isolation. The 4-hydroxybenzoic acid was obtained as the only main monomeric product from the process. The
yield of 4-hydroxybenzoic acid can reach 7.87% based on the amount of oil palm empty fruit lignin. The sodium hydroxide concentration is the most important factor that affects the 4-hydroxybenzoic acid production yield and selectivity. The possible 4-hydroxybenzoic acid production routes were proposed. And the production route is considered to be formed mainly by the cleavage of C-O bonds at the
γ-hydroxyl position of the syringyl unit in oil palm empty fruit bunch lignin.

Authors: Moulessehoul Wassila , Moulfi Bouchra , Ferouani Souheyla , Ziani-Kerarti Djalal
Published: May 2023

In this work, using CST simulation software, we simulated a nano rectangular graphene patch antenna for optical transmission. The chosen dielectric substrate is RT6010 (εr = 3.55) with thickness 2.2 μm. The proposed antenna gives one peak of frequency at 6 THz with return loss of -43.531 dB and a radiation pattern of 5.26 dBi. To improve the performance of the antenna, we simulate the antenna with a relaxation time of 1 ps, 3 ps, and 5 ps. The proposed antenna can be integrated and used for optical transmission.
Mathematical modeling of the metrical parameters of hexagonal close-packed metalls
Authors: Sechenykh P. A.
Published: May 2023

The electronic, magnetic, mechanical and other properties of crystalline substances are due to the feature of their structure — the periodicity and symmetry of the lattice, therefore, the determination of the metrical parameters is an important stage in the study of the characteristics of such materials. The paper considers a number of metals having a crystal lattice of the hcp structural type (hexagonal close packing) – beryllium, cerium, cobalt, dysprosium, erbium, gadolinium, hafnium, holmium, lanthanum, lutetium, magnesium, neodymium, osmium, praseodymium, rhenium, ruthenium, scandium, terbium, titanium, thallium, thulium, yttrium, zirconium. The paper shows the application of the annealing simulation algorithm to find the metric parameters of the materials under consideration using the dense packing model, which is widely used in crystallographic calculations. The own software implementation of the annealing simulation algorithm presented in the paper makes it possible to determine the coordinates of the atoms included in the unit cell of the crystal lattice, to calculate the lattice constants and the packing density of atoms in the cell of the crystal of the hcp structural type, using the given chemical formula and space symmetry group. These structural characteristics can be used as input parameters in modeling the electronic, magnetic, and other properties of the considered materials. The paper compares the values of the crystal lattice constants obtained as a result of numerical simulation with published data.
Simulation modeling of an analog impulse neural network based on a memristor crossbar using parallel computing technologies
Authors: Morozov A. Yu. , Abgaryan K. K. , Reviznikov D. L.
Published: May 2023

The work is devoted to the issues of simulation modeling of an analog impulse neural network based on memristive elements within the framework of the problem of pattern recognition. Simulation modeling allows you to configure the network at the level of a mathematical model, and subsequently use the obtained parameters directly in the process of operation. The network model is given as a dynamic system, which can consist of tens and hundreds of thousands of ordinary differential equations. Naturally, there is a need for an efficient and parallel implementation of an appropriate simulation model. OpenMP (Open Multi-Processing) is used as a technology for parallelizing calculations, since it allows you to easily create multi-threaded applications in various programming languages. The efficiency of parallelization is evaluated on the problem of modeling the process of learning the network to recognize a set of five images of size 128 by 128 pixels, which leads to the solution of about 80 thousand differential equations. On this problem, more than a sixfold acceleration of calculations was obtained.According to experimental data, the character of memristor operation is stochastic, as evidenced by the spread in the current-voltage characteristics during switching between high-resistance and low-resistance states. To take this feature into account, a memristor model with interval parameters is used, which gives upper and lower limits on the quantities of interest, and encloses the experimental curves in corridors. When modeling the operation of the entire analog self-learning impulse neural network, each epoch of training, the parameters of the memristors are set randomly from the selected intervals. This approach makes it possible to do without the use of a stochastic mathematical apparatus, thereby further reducing computational costs.

Published: May 2023

Materials from natural raw materials are always of great demand in the sphere of construction, both large-sized structures and the smallest decoration elements. Regardless of the area of use, wood needs to be processed, whether it is protection from excessive heat and possible sources of ignition, protection from biological influences, including natural conditions, or processing in order to give an object aesthetic features, or create interior compositions. Each type of coating – enamel or paint – has a number of individual characteristics. The aim of research is to identify the relationship between the special fire-retardant paint «Pirex», which provides the first fire protection group, and general-purpose wood paint «Luxart» without a certificate of belonging to one or another fire group security. Referring to State Standard R 53292-2009, which is the basis of the research, wood samples were treated with potential fire protection, after which conclusions were presented on the effectiveness of all tests. In addition to examining the difference between fire retardant paint and general purpose paint, the effect of applied agent layers on the fire retardant properties of wood was investigated. The results of the studies carried out allow us to draw conclusions about each method of applying paint and to identify correlation dependences for each paint on the number of coating layers.

Recycling of recycled polymer raw materials, in particular PVC waste, is undoubtedly one of the key components of the modern world. A significant place among PVC-based waste is occupied by linoleum, foam, laminated wallpaper, sanitary PVC pipes, artificial leather for haberdashery and technical purposes, agricultural and insulating films, PVC hoses, containers, used packaging. Currently, there are no effective ways to recycle them, so most of the waste is disposed or incinerated.This article shows the possibility of using dispersed powder materials obtained by high-temperature shear grinding of waste from the production of polyvinyl chloride materials. The design of a rotary dispersant for carrying out the process of high-temperature shear grinding of polymer products is considered.It has been established that in the process of waste PVC material recycling simultaneously with the process of high-temperature shear grinding, it is possible to modify the polymer material by introducing 1–3 wt. fr. of metal-containing heat stabilizers and 10–30 wt. fr. of plasticizers into the feedstock. This leads to an increase in the thermal stability margin by 15–50 min and an improvement in the flow rate of the melt processed together with ester plasticizers of the material by 20–35 %, as well as an improvement in the manufacturability of the dispersion process.The conducted research suggests an economically and environmentally beneficial possibility of recycling polyvinyl chloride materials, and opens up ways to create technological schemes closed in material and energy flows.

Background: Mesoamerica is one of the most important biodiversity hotspots on the planet. Despite significant efforts made over two centuries to contribute to the floristic knowledge of this region, our understanding of its flora is still scattered and uneven.
Questions: What is the magnitude of the vascular plant species richness in the Usumacinta River Basin?
Study site and dates: Usumacinta River Basin (Guatemala and Mexico), 1838-2018.
Methods: We compiled the checklist by systematizing the floristic information acquired from various sources derived from numerous floristic and ecological studies.
Results: We recorded 6,977 species, 1,892 genera and 274 families. The largest numbers of species (5,746) and records (58,859) correspond to the Mexican portion of the Usumacinta River Basin, compared to its Guatemalan counterpart (4,445 species and 19,952 records). The most species-rich families were Orchidaceae (598 species), Fabaceae (512), and Asteraceae (476). The prevalence of these and all other families with significant contributions to the flora varied among three elevation-defined sectors into which the Usumacinta River Basin was subdivided (lower, middle, and upper basin).
Conclusions: The Usumacinta River Basin is a strategic region for plant biodiversity conservation as it hosts almost one third of all vascular plant species known for Mesoamerica and ca. 6 % of the entire flora in the Americas. Further botanical exploration should focus on those areas of the basin for which little or no information is available in order to gain a better appreciation of its flora.

Authors: KÖROĞLU Sevgi , DURAT Gügün , SEVİMLİ DİKİCİLER Bahar
Published: May 2023

Abstract: Purpose: Body dysmorphic disorder is important because it is a frequently encountered disorder in the dermatological patient group. This research aims to understand the relationship between body dysmorphic disorder and selfobjectification and competitive attitude and related factors. Method: The study was interviewed with 43 people who applied to the dermatology outpatient clinic between July 2022 and September 2022. Body Dysmorphic Disorder Screening- Self-Assessment Form was used to evaluate body dysmorphic disorder symptoms, Objectified Body Consciousness Scale was used to evaluate self-objectification, Competitive Attitude Scale was used to measure understanding of competitiveness. Study data were evaluated with t-test in independent groups, one-way analysis of variance and correlation analysis. Results: In the study, it was determined that the average age of the individuals who applied to the dermatology outpatient clinic was 26.49 and 69.8% of them were women. There was a significant positive correlation between body dysmorphic disorder symptom severity and body monitoring (rp = 0.32, p<0.05) and comparison (rp = 0.43, p<0.005) sub-dimensions; significant and negative correlations were found between body dysmorphic disorder symptom severity and competitive pleasure (rp = -0.40, p<0.05) sub-dimension. Conclusion: It is seen that watching and comparing one’s own body has a negative effect on the severity of body dysmorphic disorder. Determining the factors that feed the body monitoring and comparison behaviors will increase the success in the treatment of the dermatological patient group.
THE CORRELATION BETWEEN FOREIGN DIRECT INVESTMENTS AND EMPLOYMENT
Authors: KORKMAZ Murat , ATALAY ORAL Mükerrem , YÜCEL Ali Serdar , AYTAÇ Ayhan
Published: May 2023

Introduction: Foreign direct investment (FDI) is considered as an important source of capital inflows in developing countries such as Turkey. In addition to its various effects, FDI also affects the employment level of the host country in many ways. Purpose: This study examines the effect of foreign direct investment in Turkey on employment. Method: In order to test this relationship, annual data for the years 2013-2021 were used and the stationarity of the variables was checked by applying the ADF test. ARDL approach was applied to find the correlation among the variables. Error correction model (ECM) method was used in the study. This method was used to eliminate the imbalance between the long-term and short-term periods and to test the short and long-run causality between cointegration. Moreover, such methods as cointegration test, unit root test, long-term regression equation were used to make the study more qualified and understandable. Findings: The cointegration was found to exist between FDI and employment. Conclusion: In line with the research findings and analysis results, the importance of government incentives for foreign investors who want to make investments in Turkey emerged. Among the most significant concerns of foreign capital and investors, it has been determined that the concerns about security and financial guarantee are quite high, and this situation arises from political instability. Political and bureaucratic restrictions, sanctions, obstacles and negativities are observed to have significant effects on the activities of foreign investment capital owners in the country. This situation reduces the employment rate and creates a negative and undesired situation. Political stability is considered as the most important effect that ensures the entry of foreign capital into the country, the increase in the number of investors and the increase in the employment rate.
7.1: Taxon Group: Crustacea - Decapoda v1
Authors: Fletcher Chris
Published: May 2023

This is part of the collection "DToL Taxon-specific Standard Operating Procedures (SOPs) for Marine Metazoa", lead by the Other Metazoa Working Group. The SOP collection contains guidance on how to process the various marine Metazoa species within the scope of the Darwin Tree of Life project. The guidance specifically refers to the tissue samples needed for DNA barcoding (which takes place at the Natural History Museum (NHM) and at the Marine Biological Association (MBA)) and outlines the dissected tissues required for whole genome sequencing, which takes place at the Wellcome Sanger Institute. Every specimen is submitted for DNA barcoding first before potentially being sent to the Wellcome Sanger Institute.

Authors: Scott-Somme Kesella
Published: May 2023

This is part of the collection "DToL Taxon-specific Standard Operating Procedures (SOPs) for Marine Metazoa", lead by the Other Metazoa Working Group. The SOP collection contains guidance on how to process the various marine Metazoa species within the scope of the Darwin Tree of Life project. The guidance specifically refers to the tissue samples needed for DNA barcoding (which takes place at the Natural History Museum (NHM) and at the Marine Biological Association (MBA)) and outlines the dissected tissues required for whole genome sequencing, which takes place at the Wellcome Sanger Institute. Every specimen is submitted for DNA barcoding first before potentially being sent to the Wellcome Sanger Institute. Definition: Within Echinodermata adults are recognisable by their (usually five-point) radial symmetry and include starfish (Asteroidea), brittle stars (Ophiuroidea), sea urchins (Echinoidea), sand dollars (Clypeasteroida) and sea cucumbers (Holothuroidea), as well as the sea lilies or "stone lilies" (Crinoidea). Including: Aforementioned Asteroidea, Ophiuroidea, Echinoidea, Clypeasteroida, Holothuroidea and Crinoidea, Excluding: Species smaller than 5mm.

Dynamics of early rehabilitation care for children with autism spectrum disorder using the DIR/Floortime approach at St. Luke’s Center for Health and Development
Authors: Romanovskiy N. V.
Published: May 2023

This article analyzes the dynamics of early comprehensive psychological and pedagogical care for children aged 3 years with autism spectrum disorders (ASD) using the DIR/Floortime approach. The experimental group included 18 ASD patients aged 3 years who attended a special program in Svt. Luka’s Center for Health and Development (Moscow) on a regular basis (2–3 times a week). The comprehensive program included weekly individual classes of 4 types: Floortime therapy, kinesotherapy with elements of sensory integration, game speech therapist-defectologist, and sensory-gaming group. The control group included 19 ASD patients aged 3 years who did not attend special classes. We used the Vineland Adaptive Behavior Scale (VABS) and Functional Emotional Assessment Scale (FEAS) for examination. Children were examined at baseline and after 3 months. We found that children from the experimental group had a significant positive dynamics in their communication skills, daily living skills, motor development, desire for emotional contact, communicative initiative, and two-way interaction. Children from the control group did not demonstrate any significant dynamics of these parameters.
Dynamic electroencephalographic study of persons – mild COVID-19 convalescents
Authors: Gulyaev S. A.
Published: May 2023

Background. The term “postcovid syndrome” is firmly entrenched in medical terminology, but many aspects of its clinical manifestations are not well understood.   Aim. To establish the presence of the nature and severity of changes in the bioelectrical activity of the brain in COVID-19 survivors, as well as their relationship with the formed clinical neurological and neuropsychological syndromes during convalescence.   Materials and methods. A dynamic study was conducted of 38 COVID-19 survivors returning to work. Neurophysiological studies were carried out using the EGI-GES-300 system (128 channels). The descriptive characteristics of electroencephalograms were built on the method of studying the spectral density of the electroencephalographic signal on the surface of the scalp, and the dynamic characteristics of the signal were studied by fixing electroencephalographic microstates, using the method of D. Lemmon and T. Kenning.

   Results and conclusions. In the study, a relatively new diagnostic technique for studying cognitive impairments based on the analysis of electroencephalographic microstates was implemented, which made it possible to identify signs of functional restructuring of the neuronal macronetworks of the brain and trace the characteristic adaptation of a person during the period of convalescence.
Epilepsy in mitochondrial diseases. Clinical lecture
Authors: Kotov A. S. , Firsov K. V.
Published: May 2023

Mitochondrial dysfunction mainly affects organs with high metabolic demand, primarily the brain. Epilepsy is a common phenotypic sign of both syndromic and non-syndromic mitochondrial diseases. Epilepsy in mitochondrial diseases is poorly treatable and is often an unfavorable prognostic sign. Patients with mitochondrial epilepsy are prescribed various anti-seizure medications. Mitochondriotoxic drugs should be avoided. Descriptions of MELAS-syndrome, MERRF-syndrome, Leigh-syndrome, NARP-syndrome are given.
BIDeconomics Chile: panorama de oportunidades
Authors: Miller Sebastián J.
Published: May 2023

Chile se convirtió en el de mayor ingreso per cápita en la región y el de mejor índice de Desarrollo Humano, muy cerca del promedio de los miembros de la OCDE. Es el país de la región que más avances ha hecho en Objetivos de desarrollo Sostenible y el número 31 del mundo. Pero aun cuando persisten desafíos. Las protestas de 2019 llevaron a momentos difíciles y de la crisis surgió una oportunidad para realizar nuevas e importantes transformaciones. Afortunadamente, Chile tiene experiencia al respecto: un historial de reformas, profundas y relevantes. Si hoy son líderes regionales es gracias a esas iniciativas de cambio y no a pesar de ellas, en términos económicos, de gobernanza, sociales y ambientales. Pasado el momento más crítico de la pandemia, es tiempo de retomar la senda. Chile tardaría en cerrar varias de sus brechas muestra que en materia de pobreza le tomaría 27 años. Los mismos 27 años demoraría el sector financiero en cerrar sus brechas. Un poco más lejos están los desafíos de género (31 años), protección social y trabajo (34) y salud (35). Los mayores retos se encuentran en las áreas de infraestructura (casi 91 años para cerrar las brechas actuales), medio ambiente (116 años) y deuda y política económica (228). Este documento plantea recomendaciones puntuales para que Chile crezca de manera sostenible y con equidad. Para ello hemos dividido las recomendaciones en dos grandes propósitos: vida digna y, por otro lado, sociedad próspera y moderna.
Resiliencia laboral en Bolivia durante la pandemia de COVID-19
Authors: Urquidi Manuel
Published: May 2023

Este documento analiza la resiliencia laboral, entendida básicamente como la capacidad de asumir de manera flexible las situaciones que se den en el entorno laboral, de los principales generadores de ingresos de los hogares urbanos en Bolivia durante el periodo de restricciones de movilidad establecidos para contener la pandemia de la COVID-19. Para ello se utilizan encuestas levantadas durante el 2020 y 2021 en las nueve ciudades capitales de departamento y la ciudad de El Alto2 . El estudio examina el impacto de la pandemia en el mercado laboral y los ingresos de los trabajadores identificando los determinantes de la resiliencia laboral a nivel individual y a nivel de hogares. Los resultados indican que sin importar el tipo de definición de resiliencia laboral que se tome, el ser mujer, joven, trabajar en algún sector vulnerable, o tener a algún miembro del hogar que requiera cuidado impacta negativamente en la probabilidad de ser resiliente laboralmente. En contraste, variables que aproximan riqueza del hogar señalan que este factor aportaría a la resiliencia del principal generador de ingresos. El estudio también encontró variaciones regionales en la resiliencia, donde las ciudades del eje troncal presentan niveles más altos de resiliencia laboral que el resto de las ciudades de Bolivia. Estos hallazgos permiten sugerir como alternativas de respuesta la implementación de programas de apoyo al empleo juvenil e intervenciones para cultivar la resiliencia laboral de las mujeres a través de programas que reduzcan la carga de las tareas de cuidado. Terminando, el documento reconoce las limitaciones de datos disponibles para incluir otras variables de interés en el análisis y la necesidad de continuar con las tareas de investigación sobre esta temática.
