“…All the answers went towards what the biophysical variable represents, no students were left behind in the field of building knowledge about the physical concept taught. And this confirms that theories in the field of exact sciences do not have a degree of difficulty that is in the imagination of students, especially in basic education, what is missing is the engagement of students in a direct application of the concept [54], [55], [56], [57], [58], [59].…”

the pandemic closure brings [4], [5]. This plan was a challenge to K-12 students from Public Schools: physical exercises in which the students could learn in a playful and experiential way a concept of Natural Sciences [6]. This challenge focused on building cognitive, socio-emotional, and behavioral skills, and on quality of life through the care of the physical health of educational actors [7].The chosen concept was the "center of mass" because it is a biometric, dynamic, and contextual variable linked to body movement -kinesiology [8], [9], where students could be experienced in the quarantine period ('lockdown') through physical exercises. Also, there is a significant probabilistic relationship between the more a child is physically active (spontaneous and induced sports practices), the more the child's ability to learn and solve problems (within the zone of proximal development) [10], [11].An Interactive Model ("Change your Center of Mass!") was built based on a mathematical model with the center of mass as a dependent variable and independent variables: body mass index and vertical jump, in which students and teachers could insert data, and qualify as your center of mass is: from regular (not very active physically) to excellent (in activity with high performance). And this interaction with the Model could be a motivating factor for the student to remain active during and after the pandemic.The center of mass is a hypothetical point where the whole mass converges as if all external forces were being applied at that point. The center of mass can coincide with the center of gravity when a human body is under the influence of a uniform gravitational field [8], [12], [13]. This biophysical variable is important because it is related to the student's biomechanics and biometrics, his body volume has a direct and proportional relationship with his movement, it can be quantified (e.g. body mass index on running speed) and qualified: the perceptual effort used to get out of inertia (e.g. laziness) [14].Jumping jacks is a physical exercise in which you can study and analyze the center of mass about its induced variation because it is a vertical movement in which, over time, we can verify a variation in the position of the center of mass in student (or athlete), if students are actives and change Abstract-The pandemic caused by Sars-CoV-2 resulted in a period of physical distance and school closures. This motivated us to elaborate on some physical and psychological harm reduction plan for the students. A challenge was proposed to K-12 students from Public Schools of the Recife City: physical exercises in which the students could learn playfully and experientially a concept of Natural Sciences. The chosen concept was the "center of mass" because it is a biometric, dynamic, and contextual variable linked to body movement, which could be experienced in the quarantine period. The objectives of this work were: (i) to propose a challenge through the physical exercise to K-12 students (jumping jacks), which implies the study...

“…A árvore de decisão foi construída para que a partir da decisão em primeira ordem pela variável independente (IMC) e posteriormente pela variável dependente (circunferência abdominal) (SANTANA et al, 2015;SANTANA, 2016a;SANTANA, 2016b;SANTANA, 2017;SANTANA et al, 2017), se pudesse classificar o indivíduo mensurado biometricamente em duas classes: "não prédiagnosticado" (NPD) e "pré-diagnosticado" (PD). A partir da árvore de decisão foi construída uma régua biométrica nas escalas pré-diagnósticas segundo o IMC pré-estabelecido a ser mensurado.…”

A esquistossomose é uma doença tropical negligenciada pertencente ao grupo das infecções helmínticas, causada pelo parasita do gênero Schistosoma, que tem afetado pessoas em todo o mundo. No Brasil, cem milhões de casos foram registrados nos últimos trinta e sete anos. Os objetivos desta dissertação foram detectar uma zona pré-diagnóstica para esquistossomose na relação entre o índice de massa corporal e a circunferência abdominal de indivíduos suspeitos de terem essa doença e propor uma ferramenta e um aplicativo colaborativo que terá também um uso educacional. Os procedimentos metodológicos seguiram seis passos: i) a alimentação do banco de dados; ii) a modelagem estatística; iii) a sistematização da árvore de decisão diagnóstica pelas variáveis; iv) a construção de uma régua antropométrica e de um aplicativo colaborativo; v) a aplicação das ferramentas construídas; e, vi) a análise quali-quantitativa. As ferramentas construídas participaram de maneira eficiente para o pré-diagnóstico da esquistossomose, com a redução da passagem de pacientes da fase aguda para fases crônica e pós-crônica, contribuindo com o paciente, no sentido de qualidade e no tempo do tratamento, e com a redução de gastos pelo sistema público de saúde. O mesmo foi relatado para as atividades de ensino e aprendizagem, a utilização das ferramentas por docentes e agentes de saúde em seus ambientes de laboro pôde apresentar de forma lúdica a aplicação da árvore de decisão para o pré-diagnóstico da doença em questão, a resultar na apropriação do conteúdo e da práxis pelo aprendiz.

“…Climatic changes are likely to increase dry season duration and decrease soil moisture in tropical SDEs (Hulme and Viner, 1998;Wetherald and Manabe, 2002;Jung et al, 2010;Santana, 2016). The ecosystems were being drier over time mainly because of deficit on water balance (EMBRAPA SEMIÁRIDO, 2019).…”

“…What does sustain aridity trends in a local? The literature affirm that on short period the land use and deforestation are the main factor to the aridity (Arora, 2002;Rubel and Kottek, 2010;Marengo and Bernasconi, 2015;Salazar et al, 2015;Schwartz et al, 2015;Zarch et al, 2015;Encinas, 2016;Santana, 2016Santana, , 2017Lima et al, 2019). The others factors are described but on large period as high pressure, continental winds, rain shadow effect, and cold ocean currents according to Maliva and Missimer (2012).…”

The local climate change was registered over time (1992-2018) on different land use ecosystems, in Brazilian Semiarid area. The aimed of this work was to analyze aridity index in five ecosystems (Wild Caatinga, Caatinga on management, Cactaceae field, Eucalyptus reforestation, and Fabaceae crop), and to compare this index with environment variables. Meteorological towers and measures with porometer and psychrometers were carried out to collect the data. The main result was that the studied areas are hotter and drier. The Fabaceae crop and Eucalyptus reforestation studied ecosystems already are on Arid classification according with registered aridity index. Wild Caatinga and Cactaceae field ecosystems are on Semiarid classification, and over time Caatinga on management ecosystem pass from Semiarid to Arid classification. The five ecosystems together are classified on Arid climate. The VPD and Ψsoil were the variables more directly proportional with Aridity index to analyzed ecosystems.
