Authors: Castellano Simone Maria , Paulo Thais Reis Silva de , Simões Regina Rovigati 
Published: April 2020

Introdução: O ritmo acelerado de vida dos professores em seu ambiente de trabalho, associado às múltiplas funções desempenhadas, conferem a essa categoria um elevado nível de esforço, sendo considerada uma das profissões com maior vulnerabilidade a problemas de saúde.Objetivo: Avaliar os motivos de não adesão à prática habitual de atividade física (PHAF) em professores da Educação Básica.Métodos: Estudo seccional, de abordagem qualitativa, com amostragem por conveniência composta por 193 docentes da cidade de Uberaba-MG. Foi desenvolvido um questionário estruturado para o estudo, constituído por perguntas sobre características sociodemográficas, de saúde e quanto aos motivos da não adesão à PHAF.Resultados: Todos os professores trabalhavam em duas escolas e ministravam, em média, 34 aulas por semana. O principal motivo para a não adesão à PHAF apontado foi a falta de tempo (78,2%), seguido de cansaço (8,8%), falta de ânimo (4,6%), dinheiro (3,6%), comodismo (2,0%), preguiça (1,5%) e falta de hábito (1,0%).Conclusão: A falta de tempo e os fatores secundários estão intimamente interligados e podem estar vinculados ao estresse relacionado à atividade docente afetando a motivação em praticar exercícios. Sugere-se que sejam realizados estudos longitudinais para que seja possível inferir causalidade quanto à associação de hábitos e comportamentos ativos dos professores com a falta de aderência à PHAF. Reasons for non-Adherence to Physical Exercise in Teachers of Basic Education: A Qualitative Sectional Study Introduction: The school work environment imposes on Brazilian teachers an accelerated pace of life, which combined with the multiple functions performed lead to high levels of effort. Therefore, that profession is considered one of the most vulnerable to health problems.Objective: To evaluate the reasons for not adhering to the habitual physical activity (HPA) in Basic Education teachers.Methods: A sectional study, with a qualitative approach, with convenience sampling composed of 193 basic education teachers from the city of Uberaba-MG. A structured questionnaire was developed for the study, consisting of questions about socio-demographic characteristics, health, and reasons for non-adherence to PHAF.Results: All teachers worked in two schools and taught, on average, 34 classes per week. The main reason for not adhering to the PHAF was lack of time (78.2%), followed by fatigue (8.8%), lack of mood (4.6%), money (3.6%), (2.0%), laziness (1.5%) and lack of habit (1.0%).Conclusion: Lack of time and secondary factors are closely intertwined and may be linked to stress related to teacher activity affecting motivation in exercising. It is suggested that longitudinal studies be performed in order to infer causality regarding the association of teachers' active habits and behaviors with the lack of adherence to PHAF.

Mortes na Natação de Águas Abertas, por quê?
Authors: Di Masi Fabrizio 
Published: April 2020

Introdução:Após a divulgação da inclusão da prova de maratonas aquáticas na olimpíada de Pequim em 2008, o esporte natação em águas abertas viu seu número de novos praticantes aumentar muito. A natação em águas abertas é caracterizada por provas nos mares, lagos, lagoas, represas, rios e outros espelhos d´água. No Brasil com sua extensa costa e bacias hidrográficas gigantes, fornece locais excelentes para a prática de tal modalidade, o que se reflete num grande número de adeptos. Faz algum tempo que o anúncio de incidentes fatais nas provas de águas abertas tem se tornando mais comum. Com isso alguns autores vêm debruçando-se sobre o tema buscando esclarecer o por quê dessas mortes.Objetivo: O objetivo deste comentário foi descrever as possíveis causas dos eventos fatais em águas abertas e sugerir ações para tornar mais segura esta atividade.Conclusão: Apesar da dificuldade de determinar as causas mortis dos participantes de provas de águas abertas, é possível levantar hipóteses sobre prováveis causas, a saber: temperatura elevada da água, síndrome do QT longo, conflito autonômico, pânico. Como sugestão para evitar essas mortes sugere-se: triagem médica rigorosa, evitar temperaturas elevadas, evitar temperaturas muito baixas, provas que obedeçam a critérios de segurança (controle do número de participantes, equipe de resgate experiente e em número adequado, UTI móvel, condições ambientais e climáticas favoráveis).Deaths in Open Water Swimming, Why?Introduction: Since the inclusion of aquatic marathon competitions in the Olympic games of Beijing 2008, there was an increased number of new open water swimmers. Open water swimming is characterized by competitions at seas, lakes, lagoons, dams, rivers and other water mirrors. In Brazil, the extensive coast and enormous watersheds, offers excellent locations for the modality, which reflected by the great number of adepts. For some time, the announcement of fatal incidents has become more frequent. Thus, some authors have been researching about it and trying to understand those deaths.Objective: The aim of this commentary was to describe the possible causes of the fatal events in open waters and to suggest safety actions for such activity.Conclusion: Although there is difficulty in determining causa mortis in practitioners at open water competition, it is possible to raise hypothesis about possible causes: elevated water temperature, long QT syndrome, autonomic conflict, pulmonary edema, and panic. Aiming to prevent deaths is recommended: rigorous medical screening, avoid elevated water temperatures, avoid low temperatures, competitions must obey safety criteria (control of the number of participants, experienced rescue team and in adequate number, ambulance, favorable ambiental and climatic conditions).
Influência do alongamento muscular sobre o tempo de reação manual
Authors: Silveira Anderson Luiz Bezerra da , De Figueiredo Júlia Araujo , Vianna Ribeiro Wallace Martins , Costa César Rafael Marins 
Published: April 2020

Introdução: O alongamento muscular é uma prática popularmente realizada com o propósito de melhorar a qualidade de vida e o desempenho em atividades físicas. Alguns estudos científicos relatam efeitos deletérios desta prática relacionadas às respostas mecânicas e neurais para a realização do movimento, os quais poderiam ser diretamente interferentes em variáveis como o tempo de reação manual (TRM), visto que, rapidez e precisão nesta variável são fundamentais em diversas atividades da vida diária, em algumas profissões e, especialmente, para o desempenho em exercício.Objetivo: O presente comentário teve por objetivo examinar e discutir o efeito das diferentes técnicas e volumes de alongamento muscular sobre o TRM e suas consequências.Conclusão: O baixo volume de alongamento (≤ 30s), independentemente da técnica ou intensidade, não interfere sobre o TRM. Face ao que se apresenta na literatura sobre o tema, não é possível realizar julgamento conclusivo da associação de alto volume de alongamento (duração > 30s) com a resposta motora manual. Adicionalmente, é imperativo estudos que objetivem avaliar o efeito do alongamento sobre o TRM, em mulheres ou associado ao dimorfismo sexual.Influence of Muscle Stretching on Hand Reaction TimeIntroduction: Muscle stretching is a popular practice with the purpose of improving quality of life and performance in physical activities, although some scientific studies report negative effects related to mechanical and neural responses to the movement, which could directly interfere in variables such as hand reaction time (HRT). Since, speed and precision in this variable are fundamental in several activities of daily living, in some professions, and especially for performance in exercise.Objective: This commentary aims to examine the state of the art on the effect of different techniques and volumes of muscle stretching on HRT and its consequences.Conclusion: Literature suggests that stretching volume (≤ 30s), regardless of technique or intensity, is not able to interfere on HRT. On the other hand, it´s not possible to make a conclusive judgment on whether high stretching volume (> 30s) is able to compromise hand motor response. Additionally, other studies are imperative to evaluate the stretching effect on HRT for women, or its association to sexual dimorphism.

Rapid progress in the world regions illustrates the importance of innovative, progressive and quality education as one of the key factors for economic competitiveness. There is a need to raise the overall skill level to meet the needs of the labour market and enable people to play an active role in today's society. Education raises people's self-confidence, promotes career development, and serves as a tool for personal growth. The future society expects the individual to be the initiator of various changes and their implementer, using knowledge, skills and creative approaches to problem solving. At present, every individual needs to be involved in a variety of change processes that are first and foremost related to the implementation of their needs and the ways of doing it.
It is difficult for an adult to adapt to the demands of the new age. Various problem solving paths are being sought to facilitate the adaptation of society to the new circumstances. They are most widely described in the European Commission's White Paper (1998), which states that there is a need to:
1.	Focus on comprehensive learning.
2.	Develop understanding of the essence of things.
3.	Understand the interactions between the past and the present.
4.	Develop the potential for employment and economic life of everyone by focusing on:
•	foreign language knowledge,
•	communication skills,
•	ability to work in a team, etc.
From the above we can conclude that adult learning is one of the most pressing issues of modern society.

Abstract
Planet yield calculations may be used to inform the target selection strategy and science operations of space observatories. Forthcoming and proposed NASA missions, such as the Wide-Field Infrared Survey Telescope, the Habitable Exoplanet Imaging Mission, and the Large UV/Optical/IR Surveyor, are expected to be equipped with sensitive coronagraphs and/or starshades. We are developing a suite of numerical simulations to quantify the extent to which ground-based radial velocity (RV) surveys could boost the detection efficiency of direct imaging missions. In this paper, we discuss the first step in the process of estimating planet yields: generating synthetic planetary systems consistent with observed occurrence rates from multiple detection methods. In an attempt to self-consistently populate stars with orbiting planets, it is found that naive extrapolation of occurrence rates (mass, semimajor axis) results in an unrealistically large number density of Neptune-mass planets beyond the ice line (a ≳ 5 au), causing dynamic interactions that would destabilize orbits. We impose a stability criterion for multiplanet systems based on mutual Hill radii separation. Considering the influence of compact configurations containing Jovian-mass and Neptune-mass planets results in a marked suppression in the number of terrestrial planets that can exist at large radii. This result has a pronounced impact on planet yield calculations particularly in regions accessible to high-contrast imaging and microlensing. The dynamically compact configurations and occurrence rates that we develop may be incorporated as input into joint RV and direct imaging yield calculations to place meaningful limits on the number of detectable planets with future missions.

Abstract
With the release of Gaia DR2, it is now possible to measure the proper motions (PMs) of the lowest-mass, ultrafaint satellite galaxies in the Milky Way’s (MW) halo for the first time. Many of these faint satellites are posited to have been accreted as satellites of the Magellanic Clouds (MCs). Using their six-dimensional phase-space information, we calculate the orbital histories of 13 ultrafaint satellites and five classical dwarf spheroidals in a combined MW+LMC+SMC potential to determine which galaxies are dynamically associated with the MCs. These 18 galaxies are separated into four classes: (i) long-term Magellanic satellites that have been bound to the MCs for at least the last two consecutive orbits around the MCs (Carina 2, Carina 3, Horologium 1, Hydrus 1); (ii) Magellanic satellites that were recently captured by the MCs < 1 Gyr ago (Reticulum 2, Phoenix 2); (iii) MW satellites that have interacted with the MCs (Sculptor 1, Tucana 3, Segue 1); and (iv) MW satellites (Aquarius 2, Canes Venatici 2, Crater 2, Draco 1, Draco 2, Hydra 2, Carina, Fornax, Ursa Minor). Results are reported for a range of MW and LMC masses. Contrary to previous work, we find no dynamical association between Carina, Fornax, and the MCs. Finally, we determine that the addition of the SMC’s gravitational potential affects the longevity of satellites as members of the Magellanic system (long-term versus recently captured), but it does not change the total number of Magellanic satellites.
First Observation of a Type II Solar Radio Burst Transitioning between a Stationary and Drifting State
Authors: Chrysaphi Nicolina , Reid Hamish A. S. , Kontar Eduard P. 
Published: April 2020

Abstract
Standing shocks are believed to be responsible for stationary Type II solar radio bursts, whereas drifting Type II bursts are excited by moving shocks often related to coronal mass ejections (CMEs). Observations of either stationary or drifting Type II bursts are common, but a transition between the two states has not yet been reported. Here, we present a Type II burst which shows a clear, continuous transition from a stationary to a drifting state, the first observation of its kind. Moreover, band splitting is observed in the stationary parts of the burst, as well as intriguing negative and positive frequency-drift fine structures within the stationary emissions. The relation of the radio emissions to an observed jet and a narrow CME were investigated across multiple wavelengths, and the mechanisms leading to the transitioning Type II burst were determined. We find that a jet eruption generates a streamer-puff CME and that the interplay between the CME-driven shock and the streamer is likely to be responsible for the observed radio emissions.
