Proposição de Problemas: entendimentos
Authors: Possamai Janaína Poffo , Allevato Norma Suely Gomes
Published: July 2024

Resumo A proposição de problemas tem ganhado destaque em documentos curriculares e pesquisas atuais, em que muitas questões estão ainda em aberto, e não se manifestam clara e coerentemente nas práticas escolares. Este artigo tem como objetivo identificar e estabelecer entendimentos para as expressões formulação, elaboração, criação e proposição de problemas com vistas a subsidiar o contexto de pesquisas e práticas brasileiras, no âmbito da Educação Matemática. Para tanto, apresenta-se uma revisão da literatura retomando aspectos históricos e constituindo um referencial teórico acerca das implicações no contexto da aprendizagem matemática e da educação integral dos estudantes. Então, a partir dos resultados obtidos de um estudo de revisão sistemática realizado, e avançando na constituição de um corpo teórico, apresenta-se os sentidos atribuídos a essas expressões, em diversos estudos brasileiros e internacionais, para, então, serem apresentadas as definições por nós assumidas: entendemos que a criação de problemas envolve os processos de formulação e elaboração de problemas e está inserida na proposição de problemas, que avança para apresentar o problema criado para um potencial resolvedor. A relevância dessas definições explicitadas abrange tanto contextos de práticas educativas que contemplem a associação com a resolução de problemas, quanto a pesquisa em Educação Matemática, com condicionamentos e reflexos sobre a coleta e análise de dados, com vistas ao aprofundamento das compreensões acerca de aspectos específicos ligados à proposição de problemas a serem considerados em estudos futuros.

Published: July 2024

ABSTRACT The increased demand for white teeth has intensified the commercialization of new bleaching products, particularly those that can be accessed easily, do not require the direct supervision of a dentist, and are affordable. Among these new products, several dentifrices publicized as bleaching products have been developed, most recent of them being the activated charcoal toothpaste, which entered the market promising to whiten teeth. While it is portrayed as a healthy and ecological product, there is a paucity of scientific evidence supporting its alleged benefits. Therefore, this literature review aimed to evaluate activated charcoal containing oral hygiene products on their bleaching ability and effects on enamel. After analyzing several in vitro studies on the subject, it can be concluded that these products do not have a bleaching effect per se, but act by removing the extrinsic pigments from the teeth. However, most of the products containing activated charcoal could have abrasive effects on the surface of the enamel. Therefore, it is suggested caution about the indication of these dentifrices, especially for individuals predisposed to dental wear, such as gingival recession, reduced salivary flow, and high risk of caries or dental erosion.
Elucidating leaf anatomical traits in Vereda plants: different survival strategies
Authors: Somavilla Nádia Sílvia , Montenegro Thaís Franco , Rossatto Davi Rodrigo , Kolb Rosana Marta
Published: July 2024

Abstract Vereda (palm swamp) is a savanna vegetation type widespread in the Cerrado. This environment is characterized by high irradiance levels and waterlogged soils for part of the year, resulting in hypoxic conditions, organic matter accumulation, and nutrient limitation. Due to these characteristics, we expect leaf scleromorphism to be the predominant pattern in the community, thus ensuring the survival of Vereda plants in these harsh environments. We examined the leaves of 14 species in Vereda Grande in central Brazil to identify their anatomy. We also analyzed the light availability and edaphic aspects of the soils in which these plants grow. We found high irradiance and soils which were rich in organic matter but low in nutrients; these factors limit plant growth given the elevated aluminum values and low pH (mean of 3.6). Most species had thick leaves with a thick cuticle, a well-developed mesophyll, calcium crystals, phenolic compounds, and sclerenchyma. These results corroborate the expected pattern of scleromorphism predicted by the environmental conditions to which Vereda plants are subjected. Chelonathus alatus did not show a leaf scleromorphic pattern and avoided stress in the dry period by losing its shoots.

Authors: Hentz Júnior Elmar José , Scatigna André Vito , Temponi Lívia Godinho , Caxambu Marcelo Galeazzi , Lima Laura Cristina Pires
Published: July 2024

Abstract The Iguazú region, where the Iguaçu National Park (Brazil) and the Iguazú National Park (Argentina) are located, encompasses one of the largest continuous remnants of the Atlantic Forest. It is considered a hotspot of biodiversity and an example of a region that is poorly known botanically. Even though non-tree taxa represent most of the Atlantic Forest’s plant diversity, some botanical families that are mainly herbaceous or shrubby, such as Plantaginaceae and Scrophulariaceae, are underrepresented in floristic treatments within this domain. Here, we provide a floristic account for the Plantaginaceae and Scrophulariaceae from the Iguazú and Iguaçu National Parks, including identification keys, illustrations, comments on distribution, habitat, and phenology. A total of 13 species and seven genera were documented. Of these, Stemodia is represented by three species, Bacopa, Buddleja, Mecardonia, and Scoparia are each represented by two species, and two genera, namely Plantago and Veronica, are represented by a single species. Our findings expand the knowledge about the flora of the Southern Cone, contributing important information for the establishment of biodiversity management plans and conservation priorities.
Renal tubular acidosis in hereditary transthyretin amyloidosis (ATTRv)
Authors: Fernandes Priscilla Cardim , Silva Moises Dias da , Waddington-Cruz Marcia , Gomes Carlos Perez
Published: July 2024

Abstract Introduction: Hereditary transthyretin amyloidosis (ATTRv) is a severe autosomal dominant systemic disease. It affects the peripheral and autonomic nervous systems, heart, kidneys, and eyes. Amyloid deposition has been demonstrated in the glomerular and tubulointerstitial compartments of the kidney. Therefore, urinary acidification disorders such as renal tubular acidosis (RTA) may be early manifestations of renal involvement in this population. Objective: To evaluate the prevalence of RTA in individuals with ATTRv. Methods: We included symptomatic and asymptomatic individuals with TTR mutation, older than 18 years, GFR >45 mL/min/1.73m2, without systemic metabolic acidosis. Urinary acidification protocol was performed with furosemide and fludrocortisone after 12 h of water deprivation (water deprivation test - WDT) and measurements of urine ammonium ( UNH 4 +) and titratable acidity (UTA). Proximal RTA (pRTA) was diagnosed when FEHCO3>10%. Incomplete form distal RTA (dRTA) was diagnosed if UpH>5.3. Results: We selected 49 individuals with a mean age of 40 (35.5–56.5) years, 63% of which were female, 84% were Caucasian, and mean GFR was 85.5 ± 20.5 mL/min/1.73m2. 94% had the genetic variant Val50Met and 57% were symptomatic. The prevalence of pRTA was 2% and of dRTA was 16.3%. In the subgroup with dRTA, there was no significant increase in excretion of UNH 4 + and UTA. We observed a good correlation between UpH by potentiometry and UpH dipstick. A UpH<5.5 on the dipstick had 100% sensitivity and negative predictive value to exclude dRTA. Conclusion: A high prevalence of RTA was found in individuals with TTR mutations. The UpH dipstick after WDT had good accuracy for screening for dRTA. Further studies are needed to evaluate the impact of early diagnosis and treatment of RTA in this population.

Resumo Este artigo aborda o acesso das pessoas com deficiência às ações e serviços de saúde a partir da percepção de profissionais e gestores de unidades da atenção primária de três cidades do país, considerando as dimensões “Disponibilidade e acomodação” e “Adequação”. Trata-se de um estudo de caso, que entrevistou 16 profissionais e gestores de unidades de atenção primária nas cidades de Brasília (DF), Arcoverde (PE) e Santos (SP). Na dimensão da Disponibilidade e acomodação, observaram-se barreiras arquitetônicas e urbanísticas, escassez na oferta de serviços, concentração geográfica dos equipamentos sociais e dificuldade de coordenação do cuidado. Na dimensão Adequação, percebeu-se uma ausência institucional de formação, o que contribui para dificuldade de interlocução entre os profissionais de saúde e as pessoas com deficiência. Além disso, os entrevistados apontam para a fragilidade na comunicação entre os serviços de saúde que compõem a rede de atenção. Por outro lado, a postura dos profissionais e o vínculo construído com as pessoas com deficiência se apresentaram como facilitadores do acesso. Esperava-se que os espaços mais desenvolvidos apresentassem mais possibilidades de acesso, mas seja na capital do país, na região mais rica do Brasil ou no sertão nordestino, essa é ainda uma luta que precisa resistir.

The evolving developmental role of the state as public trustee of South Africa's natural resources and property
Authors: September-Van Huffel Anthea-Lee
Published: July 2024

Through its environmental laws and policies, the state needs to ensure the ecologically sustainable development and use of South Africa's natural resources, while promoting justifiable economic and social development. Thus, the view that property owners may not use their property in ways that prejudice the community and other peoples' interests in environmental resources must be considered. This corresponds with the acknowledged stance that property, in its widest sense, has a "public or civic or proprietary" aspect to it that transcends individual economic interests, and that private property ownership should be inherently limited for the benefit of society at large. Property is, therefore, intimately bound up with the socio-economic security and well-being of all South African citizens. Since a developmental state actively guides economic development and the use of the country's resources to meet the needs of the people, the developmental role of the state should serve the public interest. In South Africa, though, the public function of property is frequently usurped by the government's developmental-state ambitions and influenced by political and economic considerations that affect the socio-economic fabric of the country. The South African government, as public trustee of the nation's natural resources, must regulate access to and use of natural resources by exercising its stewardship ethic. However, this is not always the case when it comes to critical resources like water and land - a situation that perpetuates the historically imbalanced distribution of wealth in South Africa.
I'm a "Savage": Exploring Megan Thee Stallion's Use of the Politics of Articulation to Subvert the Androcentric Discourses of Women in Hip Hop Culture
Authors: Rajah Azra
Published: July 2024

Hip hop music is understood to be a tool that promotes equality for a group of people who were previously marginalised and discriminated against. However, misogyny and sexual exploitation of women remain dominant characteristics of hip hop culture. When exploring research on women in hip hop culture, scholars tend to focus on misogyny and the hypersexualising of women, thus disregarding the fact that women can express and enjoy their sexuality purely because it is their prerogative to do so. This article highlights how Fairclough's (1995) model of critical discourse analysis can be used as a lens and tool to introduce alternative perspectives on these discourses and ideologies. Specifically, this research interrogates how Megan Thee Stallion applies the politics of articulation through her rap lyrics to subvert the androcentric discourses of hip hop culture, which objectify and sexually exploit women-specifically, Black women who have been historically subjected to the politics of respectability that positions Black women in inferior position to White women.
“Los artículos de costumbres son de gran importancia”. Miradas sobre los bailes de salón en Bogotá en el siglo XIX
Authors: Torres L. Rondy F.
Published: July 2024

El presente artículo, propone una lectura de dos cuadros de costumbres escritos por Juan Crisóstomo Osorio Ricaurte (1836-1887) y José Caicedo Rojas (1816-1898). En ellos aparecen situaciones que contradicen imaginarios de distinción social y elegancia relacionados con los bailes de salón que prevalecen en los estudios sobre la música en el siglo XIX realizados en el país. Se trata de “Quejas al Mono de la Pila" (1859) de Osorio Ricaurte y “El duende en un baile” (1846) de Caicedo Rojas. Enunciados desde un yo narrativo, describen y denuncian, ofensa tras ofensa, a lo que se entendía como buenas costumbres. Dicho análisis sugiere, en última instancia, que los cuadros de costumbre constituyen un valioso repertorio literario con visos de proto-etnología que, alimentado con reseñas de viajeros y con iconografía, nos permite entender con mayor clarividencia la variedad de espacios que abría la música en el siglo XIX, variedad que el relato oficial no se vislumbra.
Botulinum toxin combined with static progressive stretching improves fibrous stiffness of knee joint in rats through TGF-β1/Smad pathway

Published: July 2024

Joint stiffness and fibrosis are common complications that affect mobility and quality of life, necessitating effective therapeutic strategies to alleviate these issues. The study aimed to observe the therapeutic effect of static progressive stretching (SPS) combined with botulinum toxin type A (BTX-A) on knee joint stiffness in rats and its effect on the transforming growth factor beta 1 (TGF-β1)/small mother against decapentaplegic (Smad) pathway in the development of joint capsule fibrosis. Forty Sprague Dawley rats were randomly divided into the blank control group, model control group, SPS intervention group, BTX-A intervention group, and SPS combined with BTX-A intervention group. Except for the blank control group, the right knee joints of the other rats were surgically fixed with Kirschner wire internal immobilization in full flexion for four weeks to form joint flexion contracture and cause fibrotic stiffness of the joint. The therapeutic effect of each intervention was assessed by the range of motion (ROM) of the knee joint, joint stiffness, the number of total cells, and collagen deposition in the posterior joint capsule, as well as the protein level expressions of  TGF-β1, Smad2, Smad3, Smad4, p-Smad2/3, collagen I and III, and alpha smooth muscle actin (α-SMA) in the posterior joint capsule in the TGF-β1/Smad pathway. SPS combined with BTX-A was more effective in relieving joint fibrosis stiffness, improving the histopathological changes in the posterior joint capsule, and suppressing the high expression of target proteins and the overactivated TGF-β1/Smad pathway. The overactivated TGF-β1/Smad pathway was involved in the formation of knee joint fibrosis stiffness in rats. SPS combined with BTX-A was effective in relieving joint flexion contracture and fibrosis of the joint capsule. Moreover, the inhibition of the overactivated TGF-β1/Smad pathway may be the potential molecular mechanism for its therapeutic effect.

Published: July 2024

Kalp kapakçığı doku mühendisliğinde mevcut tedavilerin dezavantajlarının üstesinden gelebilmek için hücresizleştirme çalışmaları yapılmaktadır. Hücresizleştirmenin temel amacı biyolojik kökenli greftlerin immünojenikliğini gidermek, doğal doku mimarisini koruyarak yeniden hücreselliği temin edecek bir iskele elde etmektir. SD ve SDS hücresizleştirme çalışmalarında sık kullanılan deterjan türevlerindendir. Çalışmamızın amacı, düşük yoğunluklu SDS ve SD deterjanları birlikte kullanılarak Merinos cinsi genç koyunların pulmoner kalp kapakçıklarının hücresizleştirilmesi ve ardından klinik çalışmalara uygun olup olmadığını belirlemek için ayrıntılı karakterizasyonlarının gerçekleştirilmesidir. 4-6 aylık koyunların pulmoner kalp kapakçıkları deterjan solüsyonunda 24 saat boyunca hücresizleştirildi. Hücresizleştirmenin etkinliğini belirlemek için kalıntı DNA miktarı ölçüldü. Ardından histolojik boyamalarla hücresizleştirmenin ECM üzerindeki etkisi incelendi. Ayrıca iskelelerin yüzey morfolojilerini belirlemek için örnekler SEM ile görüntülendi. Hücresizleştirmenin biyomekanik özellikler üzerindeki etkisini incelemek için tek eksenli çekme testi yapıldı. Sonuçlar, hücresizleştirmeden sonra kontrol grubuna göre hücresizleştirilmiş yaprakçık ve arter kısımlarından %94 ve %98 oranında DNA giderimini gösterdi. Histolojik boyamalarda herhangi bir hücre çekirdeğine rastlanmadı ve 3 katmanlı yaprakçık yapısının korunduğu gözlendi. Çekme testi sonucunda UTS ve elastisite modülünde kontrol grubu ve hücresizleştirilmiş gruplar arasında istatistiksel olarak anlamlı farklılık gözlenmediği ve biyomekanik özelliklerin değişmediği belirlendi. Sonuç olarak hücresizleştirilmiş Merinos cinsi genç koyunların pulmoner kapakçıklarının, kalp kapakçığı doku mühendisliği çalışmalarında başlangıç matrisi olarak kullanılabileceğini öneriyoruz.
Yapı bilgi modelleme (BIM) ile binaların yangın emniyeti performansının değerlendirilmesi
Authors: Beşiroğlu Şafak , Serteser Nuri
Published: July 2024

Teknolojinin gelişmesiyle eşzamanlı olarak modelleme tekniklerinin kullanımı, sektörlerindeki aktörler arasında popülerlik kazanmıştır. Bununla birlikte Yapı Bilgi Modelleme (BIM), çoğu tasarım disiplininde yaygın olarak kullanılsa da yangın emniyeti alanında kullanım oranı henüz diğer alanlardaki düzeyde değildir. Bu çalışmada, BIM ortamında en bilinen yazılımlardan biri Revit ile modellenen ofis binası, belirlenen yangın emniyeti kriterlerine göre CYPEFIRE Design ve FINEFIRE yazılımları kullanılarak incelenmiştir. Ofis binasının sağlaması gereken yangın emniyetine yönelik kriterler, Binaların Yangından Koruması Hakkında Yönetmelik ve ilgili standartlar esas alınarak oluşturulmuştur. Yazılımlar, EN ISO 9241-11 standardı ile uyumlu olarak “kullanılabilirlik” açısından öğrenilebilirlik, yeterlik, akılda kalıcılık, hatalar ve memnuniyet parametrelerine göre değerlendirilmiştir. Yapılan çalışmalar sonucunda CYPEFIRE Design, belirlenen 25 yangın emniyet kriteri için yönetmelik ve standartlara göre 13 (%52); FINEFIRE 10 (%40) uygunluk kontrolü sağlamıştır. Kullanılabilirlik parametrelerinden yeterlik ve hatalar parametrelerinin değerlendirmesinde CYPEFIRE Design, öğrenilebilirlik ve akılda kalıcılık parametreleri açısından FINEFIRE öne çıkmaktadır. Her iki yazılımın yangın emniyetiyle ilgili birbirine göre üstünlük sağladığı uygulamalar bulunmaktadır. Sonuç olarak, BIM ortamında yangın emniyet önlemlerinin tüm yapıda uygulanmasına imkan veren bu yazılımların kullanımı, proje sürecinin daha hızlı ve interaktif yürütülmesini sağlamaktadır. Binanın mimari proje süreci ile birlikte yürütülmesi gereken yangın emniyet önlemlerinin projeye uygulanmasında BIM teknolojisi kullanımı, yakın gelecekte daha yaygın ve kapsamlı hale gelecektir.

Radiopacity and Microleakage Evaluation of Different Intermediate Materials
Authors: Yazkan Başak , Açikgöz Gözde
Published: July 2024

Objective: The aim of this study is to compare the radiopacities of different types of materials with indications for application as a base under restorations and the microleakage of the final restorations with these materials applied as bases.
Methods: Standart Class I cavities were prepared in 90 caries-free molar teeth. The cavities were randomly divided into 9 groups according to the type of intermediate material to be applied (n=10): 1. High flowable composite, 2. Low flowable composite, 3. Fiber reinforced composite, 4. Giomer, 5. Ormocer, 6. Alkasite, 7. Bioactive composite, 8. High viscosity glass ionomer, 9. Glass carbomer. The base materials in each group were applied to the cavity floor and restoration was completed using a nanohybrid composite resin and an universal adhesive system. To evaluate radiopacity, radiographic images were taken using direct digital system and mean gray values were measured with ImageJ software. To analyse microleakage, specimens were subjected to thermocycling, immersed in 2% methylene blue solution for 24 hours, sectioned buccolingually and leakage values observed on the half-piece surfaces were examined under a stereomicroscope and recorded. Data were analysed using One-way Analysis of Variance, Tukey HSD Test and Pearson Chi-Square with Bonferroni-corrected Z Test (p˂0.05).
Results: In terms of radiopacity, while alkasite and low flowable composite showed the highest radiopacity, glass carbomer gave the lowest (p

Scientific and Technical Translation on the Revisited Maps of Translation and Translation Studies
Authors: MYKHAILENKO Olena ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: July 2024

Historically, scientific knowledge has proven to be a mobile form of culture. Translation is what has rendered this knowledge mobile. Scott L. Montgomery, ‘Scientific translation’ This paper looks into the core of scientific and technical translation, with regard to the nature of science and technology texts. The article revises the research opinions on the development of similar and different features of these translation types and highlights the importance of their differentiation, notwithstanding that it is generally convenient to group science and technology together. The research attempts to prove that though scientific translation and technical translation are closely connected domains, they are not identical and the terms ‘scientific’ and ‘technical’ are not interchangeable. Of particular research interest is the studying of scientific translation and technical translation as separate fields within the translation science. The article analyses the existing bibliography maps of translation and Translation Studies, to find out that scientific translation and technical translation have quite recently found their place as distinct fields on the map of translation. However, on the map of Translation Studies, these translation types are not yet present. The assumption for this investigation was that theories of scientific and technical translation, among others, are highly likely to be established within specialized translation and they need a comprehensive methodological research. There is much prospect for these theories to be developed, provided that major recent theoretical works in the field are systematised.

Here, we review the latest available studies on using surfactant lavage in newborns with severe manifestations of meconium aspiration syndrome (MAS), illustrated by a representative clinical case. Meconium-stained amniotic fluid may be found in 8-20 % of all births, with the incidence reaching 23-52 % after a full 42 weeks of gestation. From 2 to 9 % of newborns with meconium-stained amniotic fluid subsequently develop MAS clinical signs. About a third of newborns with MAS require tracheal intubation and mechanical ventilation. MAS-related mortality rate due to severe injuries of the lung parenchyma and the development of pulmonary hypertension, can exceed 20 %. Other complications, including air leak syndrome (ALS), occur in 10-30 % of children with MAS. Surfactant lavage may be one of the clinical tools that avoids extracorporeal membrane oxygenation (ECMO) in severe MAS cases. This clinical observation is also of interest because a mature, even post-term newborn with MAS subsequently developed a typical bronchopulmonary dysplasia (BPD), which required proper treatment.

Assessment of evoked potentials using electroencephalography is a classic method for determining a person's response to different types of stimuli. The literature describes EPs that are specific markers of emotional perception. To date, many stimulus bases have been developed and validated for use in EEG EP paradigms, among which images of human faces with emotional expression stand out. It is possible that the perception of this type of stimulus may have its own specificity — for example, it may occur faster than the perception of other classes of images, since it represents a more significant biological signal. In this review, we wanted to show the features of using affective images in the oddball paradigm, focusing on the use of human faces with emotional expression. This paradigm also belongs to the EEG/EP paradigms, but it has several features. The advantages of this technique are, firstly, its higher sensitivity compared to other paradigms with the presentation of emotional images. Secondly, it is possible, during the passive presentation of visual stimuli, to analyze the rapid automatic reactions that, according to previous studies, accompany the perception of faces. Perhaps the most effective images in the oddball EEG/EP paradigm will be facial expressions. The obtained data by using this paradigm are presented. The data obtained data show differences in both the amplitude and spatial components of the EP associated with different facial expressions — happy/angry.
Error-Related Negativity (ERN) as a Neural Сorrelate of Executive Functions: A Narrative Review
Authors: Evgeniy M.G. , Talantseva O.I. , Momotenko D.A.
Published: July 2024

Executive functions are a set of high-level cognitive processes that regulate human behavior and cognition, and are necessary for adaptive and goal-directed behavior. The error monitoring process can be considered as a condition preceding the enhancement or activation of executive control. The neural correlate of this condition is the error-related negativity (ERN). This article presents a narrative review of research investigating cognitive and affective aspects of the error monitoring process in the context of executive functions using the ERN. The literature review on the affective aspect revealed a diversity of approaches to influencing the state of participants. Most works take into account information about participants' state or affectively salient aspects of stimuli perception. However, this information may not be sufficient to establish a link to the response to conflict induced by an error in an experimental task. Presumably, the general emotional state has only an indirect influence on the error monitoring process. This may be the reason for the inconsistent results observed in this area of research.
Implicit False Beliefs: The State of Art
Authors: Lebedeva E.I. , Ilina E.A.
Published: July 2024

The article presents a review of a number of modern foreign studies of implicit false beliefs in young children with typical development, hearing impairments, autism spectrum disorders, and primates. The results of studies performed using different methodological paradigms for assessing early development of mental models: violation of expectations and anticipatory looking are analyzed. The results of research on the search for the biological basis of the origins of social cognition using functional near-infrared spectroscopy are presented, as well as the results of research on the relationship between possible predictors of theory of mind (understanding the purpose of another's actions, joint attention, implicit false beliefs) and the success of social cognition in preschool age under typical development. Theoretical conceptualizations of two theory of mind systems are described: the minimal one and the theory of mind. Immediate prospects for future research to resolve existing replication crises and prevent new ones are outlined.
Bilingual Language Experience and Executive Functions: Current State of Research
Authors: Semenova E.Y.
Published: July 2024

Bilingualism has been claimed to enhance executive functions, as evidenced by studies comparing bilinguals and monolinguals across various executive function tasks. Despite this assertion, recent systematic reviews and meta-analyses reveal contradictory findings, challenging the existence of the “bilingual advantage” phenomenon. The variability in results is attributed not to the data obtained but rather to the diverse methodological paradigms utilized across studies. This article analyzes the operationalization of bilingualism and executive functions in contemporary research alongside a critical examination of the theoretical underpinnings linking bilingualism and executive functions. The paper concludes by outlining avenues for future research, emphasizing the necessity for researchers to account for individual bilingualism-related factors and specifics of the executive function tasks. Furthermore, it advocates for the development of new falsifiable theories that suggest testable hypotheses, thus advancing the field's understanding of bilinguals’ executive functioning.

Authors: Rykov M. Yu. , Venediktova M. G.
Published: July 2024

About 400 thousand of new cases of endometrial cancer is registered in the world every year. Previously uncommon (for this type of malignancy) metastatic sites, such as brain or skin, have been observed over the past 15 years. Skin metastases of endometrial cancer are extremely rare and occur in less than 1 % of cases. We present a clinical case of atypical metastasis of endometrial cancer to the skin of the pubic region in a patient who underwent combined treatment.

Objetive. Soccer and futsal are two modalities widely practiced worldwide, so the aim is to compare the results of morphofunctional evaluations in professional teams in Bogota. Methodology. This was a quantitative, non-experimental, cross-sectional study. For the morphological evaluation, body composition was evaluated and for the functional evaluation, VO2max, explosive and maximal strength were evaluated. Results. Significant differences were found in the four variables evaluated. In the percentage of body fat mass the value was 14.7%±3.4 in Soccer 11, indoor soccer with 18.3%±5.9. As for power, they obtained 252.5 watts ±48.3 in 11-a-side soccer and 201.4 watts ± 33.2 in indoor soccer. The Vo2 max variable showed an average of 53.2 ml/kg/min±4.0 in 11-a-side soccer and 43.9 ml/kg/min±14.8 in indoor soccer. In maximum strength, they had values of 813.9 kg/f±177.4 in 11-a-side soccer, compared to indoor soccer with values of 552.1 kg/f±174.4. Finally, in maximum power, a mean of 546.15watts was found for 11-a-side soccer; while futsal was 292.27watts. Conclusions. The variables Vo2max and maximum strength are the most outstanding in terms of means and standard deviations due to their p<0.05 values; which indicates that 11-a-side soccer athletes tend to have better morphofunctional characteristics compared to indoor soccer.

Las tiendas de barrio es un motor de la economía del país, no obstante, están expuestas a situaciones como la llegada de tiendas de descuento, el uso de canales digitales, los cambios en los hábitos de consumo, las deficientes estructuras físicas, entre otros, por tanto, es relevante el estudio de las variables exógenas para pronosticar su efecto sobre las ventas. El objetivo de este estudio es modelar econométricamente para pronosticar el efecto de las variables exógenas en las ventas de las tiendas de barrio. La investigación utiliza un método cuantitativo, descriptiva, correlacional, de campo, con dos fases, en la primera la aplicación de un instrumento de medición a una muestra por conglomerados de 66 tiendas. A partir de los datos recaudados en una segunda fase se probaron los modelos econométricos para establecer el efecto de las variables exógenas en las ventas de las tiendas de barrio. En función de los valores encontrados en el modelo propuesto se puede inferir que la variable de mayor influencia es la tasa de desempleo, seguida por la tasa de empleo y la inflación. Se concluye que es importante que las tiendas de barrio reflexionen sobre los efectos que tienen sobre su actividad comercial las variables de entorno para estar preparadas en momentos de crisis económica y lograr ser sostenibles financieramente. El estudio sugiere el conocimiento que deben tener los tenderos de las variables exógenas a fin de optimizar sus ventas y no verse inmersos en situaciones financieras inestables.
