Abstract Objective Evaluate autonomic function and low-grade inflammation and characterize the correlation between these variables in schoolchildren with obesity living in the Brazilian northeast region. Methods 84 children with obesity and 41 with normal weight were included in this cross-sectional study. Anthropometry, body composition, blood pressure (BP), inflammatory biomarkers, and heart rate variability (HRV) indexes were analyzed in children aged 7 to 11 years. Results children with obesity had increased systolic (p= 0.0017) and diastolic (p= 0.0131) BP and heart rate (p= 0.0022). The children with obesity displayed significantly lower SDNN, RMSSD, NN50, HF (ms), HF (nu), SD1, SD2, and higher LF (ms), LF (nu), LF/HF, SD1/SD2, DFA-α1, and DFA-α2, compared to normal weight. A lower and higher capacity for producing IL-10 (p= 0.039) and IL-2 (p= 0.009), respectively, were found in children with obesity compared to children with normal weight. Although IL-2, IL-4 and IL17A did not correlate with HRV parameters, IL-6 was positively correlated with SDNN, LF (ms) and SD2, TNF-α was positively correlated with LF/HF and SD1/SD2 ratio, and IFN-γ was positively correlated with SDNN, RMMSSD, NN50, LF (ms), HF (ms), SD1, and SD2. Conclusions The findings suggest that children with obesity have impaired autonomic function and systemic low-grade inflammation compared to children within the normal weight range, the inflammatory biomarkers were correlated with HRV parameters in schoolchildren living in the northeastern region of Brazil.

ABSTRACT Volleyball performance depends partially on lower limb strength. The phase angle (PhA) is a marker of functional muscle mass and a surrogate measure of athletic muscle performance. This study aimed to verify the correlation between PhA (bioimpedance) and lower limb muscle strength in young volleyball athletes. The sample included 38 young male volleyball athletes (Age: 16.7± 1.3 years; Weight: 73.7± 9.7 kg; Height: 179.3± 6.9 cm). We performed a cross-sectional observational study and evaluated the volleyball athletes for vertical jump tests (Counter-Movement Jump: CMJ and Squat Jump: SJ) and whole-body bioimpedance. The Pearson test showed positive and moderate significant correlations between the PhA, CMJ, and SJ (r= 0.550 and r= 0.559, respectively). Our findings demonstrated that assessing the PhA through bioimpedance provides relevant measures of muscle strength and power in young volleyball athletes.

ABSTRACT Football is a sport that involves a combination of continuous and intermittent effort. Therefore, players need to be able to recover quickly between moments of high intensity to continue to perform at a high level of output throughout the entire match. The present study aimed to evaluate the effect of an intermittent exercise protocol on the rate of high-intensive force production through the countermovement test (CMJ) in elite Portuguese female soccer players. The sample consisted of 12 players from the first division of women's football in Portugal (Age= 18.1± 0.9 years; Weight= 60.10± 5.8 Kg; Height= 1.63± 4.8 cm; BMI= 22.48± 1.5 kg/m2). The players performed an intermittent exercise protocol on a cycle ergometer, lasting 8 minutes, in which each minute corresponded to 40 seconds of high-intensity (4 W/kg, based on the player's body weight) and 20 seconds of low-intensity (75W). Before and after the protocol, the players performed the CMJ. Through the results obtained, it was possible to observe that players presented a significant decrease in the height of the CMJ between the two moments (before- 29.92± 3.55 cm vs after- 26.92± 4.05 cm; p < .01). The present study allowed us to conclude that intermittent exercise protocol promoted a negative influence on CMJ performance.

ABSTRACT Paricá is a native tree to the Amazon region recognized for several socioeconomic applications. However, there are few studies on the influence of irrigation regime in the seedling stage. Thus, the objective of the research was to evaluate the effect of water depths and irrigation frequency on the development of Paricá seedlings in the edaphoclimatic conditions of the Amazon region. The experiment was conducted in a greenhouse at the Federal Rural University of the Amazon (UFRA), Capitão Poço Campus, located in Capitão Poço, Pará, Brazil. The experimental design was randomized blocks, in 5x2 factorial arrangements, consisting of five irrigation depths and two irrigation frequencies, with four replications. The highest irrigation depth (725 mL) at daily frequency resulted in lowest biomass production maybe due to hypoxia in the root zone. In contrast the every three day irrigation promoted high biomass production with the highest irrigation depth (725 mL). Contrarily, 435 mL depth produces high quality seedlings at daily irrigation frequency. Regarding the rational use of water, producers may use 725 mL at 3-day frequency, given that it has promoted high seedling quality and provides savings of 580 mL compared to the best water depth on the daily irrigation (435 mL).

Abstract School meritocracy is a system for rewarding students with benefits assumed for motivation and recognition of effort, but also with a negative dimension associated with the intensification and stratification of inequalities. Thus, the main objective of the present study is to analyze the literature on school meritocracy and the logics of action of schools in this context. The method used is a scoping review, aimed at selecting, analyzing and synthesizing the literature found in four databases: Web of Science, Scopus, RCAAP and Google Scholar. The results show a need for reflection on the concepts of school justice and exclusion, associated with meritocratic ideology in the logic of equal opportunities.

Abstract The primary objective of this scoping review, carried out using Arksey and O’Malley’s methodological framework, is to understand the organizational, cultural and pedagogical changes generated by Professional Learning Communities in schools over the last five years, and to find gaps in the reviewed literature that could guide future research. The results indicate that, although studies on these communities are numerous and reveal their positive effects, they are essentially based on a theoretical and conceptual understanding of their construct, on short-term activities, and in limited situational contexts. There is, thus, a noticeable lack of research studying such communities from a longitudinal perspective and as drivers for building learning organizations.

Résumé L’objectif principal de cette scoping review, réalisée suivant le cadre méthodologique d’Arksey et O’Malley, est de comprendre les changements organisationnels, culturels et pédagogiques générés par les communautés d’apprentissage professionnelles en milieu scolaire au cours des cinq dernières années et d’identifier dans la littérature des lacunes permettant de guider de futures recherches. Bien qu’il existe de nombreuses études sur ces communautés révélant leurs effets positifs, les résultats indiquent que ces dernières sont essentiellement basées sur une compréhension théorique et conceptuelle de leur construct, ainsi que sur des activités à court terme dans des contextes situationnels limités. On constate donc une carence de recherches sur ces communautés dans une perspective longitudinale et comme forces motrices de la construction d’organisations apprenantes.

Resumen El objetivo central de esta scoping review, realizada según el cuadro metodológico de Arksey y O’Malley, es comprender los cambios organizacionales, culturales y pedagógicos generados por las Comunidades Profesionales de Aprendizaje, en el medio escolar, en los últimos cinco años, y encontrar, en la literatura revisada, lagunas que pueden informar futuras investigaciones. Los resultados indican que, si bien los estudios sobre estas comunidades son numerosos y revelan sus efectos positivos, ellos están, esencialmente, fundamentados en la comprensión teórica y conceptual de su constructo, en actividades de corto plazo y en contextos situacionales limitados. Se constata, así, una escasez de investigaciones que estudien dichas comunidades desde una perspectiva longitudinal y como impulsoras de la construcción de organizaciones de aprendizaje.

Abstract This study aimed to develop and evaluate bread with the use of pulp and flours of pequi, in partial replacement of water and wheat flour, to develop a bakery product with good technological, nutritional and sensorial qualities. The pequi husk and pulp flours were obtained by means of a thermal pre-treatment, oven drying and standardization of the dry material. Whereas, the bread formulation was defined through the baker’s formulation. Besides, the dehydration process caused significant changes (p<0.05) in the L* value and chromaticity (C*), mainly of the flours (husk and pequi pulp), such changes are due to non-enzymatic oxidative processes and pigment degradation, especially carotenoids. The effect of the substitution of ingredients (wheat flour and water) by husk and pulp flours and pequi pulp contributed to the increase in lipid, crude fiber, nitrogen-free extract and energy value content. However, the substitution promoted changes in the attributes of color and textural properties, such as increased hardness, chewiness and cohesiveness. Nevertheless, all formulations showed good sensory acceptance and thus, pequi sweet breads can be implemented in school meals for contributing and meeting the nutritional recommendations established by the School Feeding Brazilian Program (PNAE).

Abstract Introduction The preservation of bone mass in elderly women is associated with better levels of practice of systematic physical exercises. Aerobic training combined with blood flow restriction seems to be a new alternative that determines this process, but knowledge gaps are still observed when referring to exercise associated with blood flow restriction (BFR) and adaptations on bone variables. Objective To analyze the chronic effects of aerobic training with and without BFR on bone mineral density and bone biomarker osteocalcin concentrations in older women. Methods Thirty women were randomized into the following groups: walking on a treadmill at low intensity with BFR; moderate treadmill walking with no BFR; only BFR (no exercise) for 20 minutes, twice a week, for 24 weeks. Bone mineral density was measured before and 24 weeks after intervention. Blood serum osteocalcin concentrations were measured before, 12 and 24 weeks after intervention. Results There were no differences between groups in bone mineral density (femoral neck, p = 0.31; total femur, p = 0.17; lumbar spin, p = 0.06) and osteocalcine (W(2) = 0.27; p = 0.87) ouctomes after 24 weeks of intervention. Conclusion There was no difference between walking training, blood flow restriction only, or walking+blood flow restriction on bone mineral density and osteocalcin concentrations after 24-weeks of intervention in older women with osteopenia/osteoporosis.

Resumo Introdução A preservação da massa óssea em mulheres idosas está associada a melhores níveis de prática de exercícios físicos sistemáticos. O treinamento aeróbico combinado com restrição de fluxo sanguíneo (RFS) parece ser uma nova alternativa que determina esse processo, mas ainda são observadas lacunas de conhecimento quando se refere ao exercício associado à RFS e adaptações nas variáveis ósseas. Objetivo Analisar os efeitos crônicos do treinamento aeróbico com e sem RFS na densidade mineral óssea e nas concentrações do biomarcador ósseo osteocalcina em mulheres idosas. Métodos Trinta mulheres foram randomizadas nos seguintes grupos: caminhada em esteira de baixa intensidade com RFS; caminhada moderada em esteira sem RFS; apenas RFS (sem exercícios) por 20 minutos, duas vezes por semana, durante 24 semanas. A densidade mineral óssea foi medida antes e 24 semanas após a intervenção. As concentrações séricas de osteocalcina no sangue foram medidas antes, 12 e 24 semanas após a intervenção. Resultados Não houve diferenças entre os grupos na densidade mineral óssea (colo do fêmur, p = 0,31; fêmur total, p = 0,17; giro lombar, p = 0,06) e osteocalcina (W(2) = 0,27; p = 0,87) após 24 semanas de intervenção. Conclusão Não houve diferença entre treinamento de caminhada, apenas restrição de fluxo sanguíneo ou caminhada + restrição de fluxo sanguíneo na densidade mineral óssea e nas concentrações de osteocalcina após 24 semanas de intervenção em mulheres idosas com osteopenia/osteoporose.

Abstract This study performed a monthly and weekly diagnostic analysis of cases and deaths of Influenza (H1N1) and Severe Acute Respiratory Syndrome (SARS) between the years 1914 and 2019 in Ceará State and their relationships with meteorological variables, precipitation and maximum and minimum temperatures. The most expressive results showed that both H1N1 and SARS have cases and deaths reported mainly from March onwards, intensifying in the austral winter and spring months. In 2018, an outbreak of H1N1 and SARS was observed in the State of Ceará with a high number of cases and deaths, mainly from SARS. On average, cases of H1N1 and SARS are low in the first 7 months of the year, and increase from August onwards reaching peak values in December. The peak of H1N1 and SARS contamination occurs in the months from the second half of the year towards the end of the year. In relation to the meteorological variables and the cases of H1N1 and SARS, the results showed that there is, in the period of greater incidence of notified cases of H1N1 and SARS, that normalized deviations of cases above the average, in the weeks of the months of September to December in most part of the years under study, suggest that the maximum and minimum temperatures in the State of Ceará were observed with values below the average. As for contamination from the influence of weekly cases of H1N1 and SARS from April to July in relation to cases from the months ahead to December, these explain, statistically with confidence of 95% according to the t-Sudent test, only of the order of 16% until 49% of cases a month ahead, being more apparent for the months of April to May, from May to June and from June to July.

Resumo O estudo apresenta uma análise da relação diagnóstica (mensal e semanal) dos casos e óbitos de Influenza (H1N1) e Síndrome Respiratória Aguda Grave (SRAG) com o comportamento das variáveis meteorológicas (precipitação e temperaturas máximas e mínimas) entre os anos de 1914 e 2019 no Estado do Ceará. Os resultados mais expressivos mostraram que tanto H1N1 como SRAG tem casos e óbitos notificados principalmente a partir do mês de março, intensificando nos meses de inverno e primavera austrais. Em média, o número de ocorrências de H1N1 e SRAG é baixo nos primeiros sete meses do ano, e aumentam partir de agosto atingindo valores máximos em dezembro. O pico da contaminação por H1N1 e SRAG ocorre nos meses a partir do segundo semestre dos anos, em direção aos meses do final do ano. Em relação às variáveis meteorológicas e os casos de H1N1 e SRAG os resultados mostraram desvios normalizados de casos acima da média nas semanas dos meses de setembro a dezembro, e sugerem que as temperaturas máximas e mínimas do ar foram observadas com valores abaixo da média. Quanto à de contaminação da influência de casos semanais de H1N1 e SRAG no período de abril a julho com relação aos casos dos meses à frente, estes explicam estatisticamente, com confiança de 95% (segundo teste t-Sudent), da ordem de 16% a 49% dos casos um mês adiante, sendo mais aparente para os meses de abril a maio, de maio a junho e de junho a julho.

Resumo Num momento de viragem de paradigma da administração educativa ao nível do centro político e administrativo, em que o discurso da autonomia das escolas tem deixado algumas marcas nos modos de gestão escolar em Portugal, é importante percecionar cada mudança de uma forma coerente e integradora. Assim, a fim de verificar se os modos de trabalho dos professores têm efetivamente mudado, é conveniente que compreendamos a(s) cultura(s) escolares que marcam o espaço em que os professores exercem a sua atividade e a influência das lideranças no modo como desenvolvem o seu trabalho, sobretudo com os colegas. Para percebermos a forma como a colaboração e as lideranças podem estar a serviço de um professor colaborativo e reflexivo, adotamos uma investigação naturalista de tipo humanista-interpretativo, conjugando uma abordagem quantitativa e qualitativa. Para caracterizarmos a(s) cultura(s) da escola, usamos processos de análise de dados baseados numa estatística de natureza descritiva, que submetemos a uma análise e interpretação estrutural e semântica. Por outro lado, para aprofundarmos alguns contextos singulares e as perspetivas de atores individuais, optamos por uma abordagem qualitativa. Analisados os dados, concluímos que, embora se note da parte da generalidade dos atores escolares uma vontade para instituir a inovação, revelada através da implementação de diferentes dinâmicas colaborativas, esta mudança tem sido muito lenta, ténue e limitada por estrangulamentos estruturais, pela falta de saber fazer e pela fragmentação ou pela balcanização inscritos na história da organização escolar portuguesa e de um corpo docente socializado numa prática profissional solitária e individualista. administrativo Portugal integradora Assim mudado s a(s culturas cultura cultura(s colegas reflexivo humanistainterpretativo, humanistainterpretativo humanista interpretativo, interpretativo humanista-interpretativo qualitativa escola descritiva semântica lado individuais inovação colaborativas lenta estruturais individualista

Abstract At a time of paradigm change in educational management in terms of the political and administrative centre, in which the discourse around the autonomy of schools has made some marks on the means of schools management in Portugal, it is important to perceive each change within a coherent and integrative framework. Thus, in order to verify whether the working modes of teachers have effectively changed, we need to grasp the school culture(s) that shape the environment(s) in which teachers engage in their activities and influence the leadership and the way they go about their tasks, especially with colleagues. In order to perceive the ways in which collaboration and leadership may be deployed in the service of collaborative and reflective teachers, we adopt a naturalist research approach of a humanist-interpretative type, combining quantitative and qualitative methodologies. In order to characterise the cultures(s) of schools, we deploy a data-based process analysing descriptive statistics subjected to structural and semantic structural interpretation. Furthermore, in order to deepen some of these unique contexts and incorporating the perspectives of individual actors, we also apply a qualitative approach. After analysis of the data, we conclude that, even while noting that the majority of actors in schools display the will to engage with innovation, demonstrated through the implementation of different collaborative dynamics, such change has only taken place very slowly and remains tenuous and limited by structural restrictions, a lack of know-how and the fragmentation and balkanisation handed down by the history of the Portuguese school organisation and teaching staff socialised in a solitary and individualist professional practices. centre Portugal framework Thus changed cultures culture s culture(s environments environment environment(s tasks colleagues humanistinterpretative humanist interpretative type methodologies culturess cultures(s databased data based interpretation Furthermore innovation dynamics restrictions knowhow know how practices

ABSTRACT Cedro-rosa (Cedrela fissilis) is native to Brazil with great potential for seedling production. However, soil correction is necessary to improve its performance, due to the edaphoclimatic conditions in Brazil, where soils have a high weathering degree and large amounts of Fe and Al oxides. Here, we evaluated the combined effect of soil acidity correction by liming and phosphate fertilization using single superphosphate on the growth and development of cedro-rosa seedlings cultivated in Amazonian soil. The study was carried out in a greenhouse at the Universidade Federal Rural da Amazônia (UFRA) – Campus Capitão Poço, between July and December 2019. Different levels of base saturation (V%) showed no influence on the variables analyzed. On the other hand, phosphorus (P), calcium (Ca), and sulfur (S) supplied by single superphosphate significantly influenced growth and development of cedro-rosa seedlings. The optimum P levels for stem diameter (SD), leaves number (LN), root dry matter (RDM), stem dry matter (StDM), leaf dry matter (LDM), total dry matter (TDM) were 405, 286, 385, 421.87, 393.75, 445 mg dm-3 of P, respectively. Seedling quality (DQI) showed a positive linear response to levels of P, Ca, and S in single superphosphate. Thus, fertilization with P was necessary at the nursery stage for the cultivation of the species in soil of low chemical fertility. For better quality of cedro-rosa seedlings grown in pots, the application of 400 mg dm-3 of P is recommended.
