Published: March 2021

PurposeThis study analysed the influence of the absence of goalkeeper and the number of goals in tactical actions in 3 configurations of small-sided and conditioned games (SSCGs): (a) goalkeeper + 3 vs. 3 + goalkeeper; (b) 3 vs. 3 (no goalkeeper); and (c) 3 vs. 3 with 2 mini goals.MethodsOverall, 24 under-15 soccer players were divided into 8 teams of 3 players each. Seven games were played for each configuration for a total of 21. The tactical behaviour was evaluated with the System of Tactical Assessment in Soccer (FUT-SAT).ResultsMore offensive actions were performed in the SSCGs with goalkeepers. The games played without goalkeepers led to more actions associated with defensive unity but also a higher rate of errors concerning the tactical principles of delay and defensive unity. In relation to the outcome of actions, more fouls, throw-ins, and corner kicks were observed in the SSCGs with 2 mini goals.ConclusionsThe games played without goalkeepers reflected a higher difficulty in managing spaces of the game and led to a higher number of errors in the performance of core defensive tactical principles. In the games played with 2 mini goals, it was observed that the players on the wings were positioned closer to each other, which made the play more fragmented compared with the other conditions. In accordance with these results, it is possible to identify the influence of goalkeepers on tactical behaviour during SSCGs.

Authors: Karimian Mohammad , Azami Milad 
Published: March 2021

IntroductionNumerous cases of pneumonia caused by coronavirus disease 2019 (COVID-19) were reported in Wuhan, China. Chest computed tomography (CT) scan is highly important in the diagnosis and follow-up of lung disease treatment. The present meta-analysis was performed to evaluate chest CT scan findings in COVID-19 patients.Material and methodsAll research steps were taken according to the Meta-Analysis of Observational Studies In Epidemiology (MOOSE) protocol and the final report was based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We registered this review at the International Prospective Register of Systematic Reviews (PROSPERO, CRD42019127858).ResultsForty eligible studies including 4598 patients with COVID-19 were used for meta-analysis. The rate of posi­tive chest CT scan in patients with COVID-19 was 94.5% (95% CI: 91.7-96.3). Bilateral lung involvement, pure ground-glass opacity (GGO), mixed (GGO pulse consolidation or reticular), consolidation, reticular, and presence of nodule findings in chest CT scan of COVID-19 pneumonia patients were respectively estimated to be 79.1% (95% CI: 70.8-85.5), 64.9% (95% CI: 54.1-74.4), 49.2% (95% CI: 35.7-62.8), 30.3% (95% CI: 19.6-43.6), 17.0% (95% CI: 3.9-50.9) and 16.6% (95% CI: 13.6-20.2). The distribution of lung lesions in patients with COVID-19 pneumonia was peripheral (70.0% [95% CI: 57.8-79.9]), central (3.9% [95% CI: 1.4-10.6]), and peripheral and central (31.1% [95% CI: 19.5-45.8]). The pulmonary lobes most commonly involved were the right lower lobe (86.5% [95% CI: 57.7-96.8]) and left lower lobe (81.0% [95% CI: 50.5-94.7]).ConclusionsThe most important outcomes in chest CT scan of patients with COVID-19 pneumonia were bilateral lung involvement, GGO or mixed (GGO pulse consolidation or reticular) patterns, thickened interlobular septa, vascular enlargement, air bronchogram sign, peripheral distribution, and left and right lower lobes involvement. Our study showed that chest CT scan has high sensitivity in the diagnosis of COVID-19, and may therefore serve as a standard method for diagnosis of COVID-19.

in children

Published: March 2021

IntroductionTo establish a cut-off value of main pulmonary artery (MPA)/descending aorta (DA) ratio and MPA/
ascending aorta (AA) ratio by computed tomography (CT) to identify pulmonary hypertension (PHT) in children.Material and methodsA total of 45 children diagnosed with PHT, who underwent both right heart catheterization
(RHC) and CT, were enrolled as a case group (PHT), and their CT findings were compared with those from a control
group (non-PHT). The widest short-axis diameters of DA at the level of the diaphragmatic outlet, AA, and MPA
at its bifurcated level were measured.ResultsThe most common indication to order a CT in the PHT group was congenital heart disease (CHD) (n = 30,
66.7%), and in the non-PHT group it was metastatic workup (n = 31, 68.9%). The median (IQR) diameters of MPA
in the PHT and the non-PHT groups were 18.7 mm (15.5, 26.7) and 16.4 mm (13.7, 19.5) (p = 0.005). The MPA/
DA ratios were 2.2 and 1.5 in the PHT and non-PHT groups (p < 0.001). The MPA/AA ratios were 1.2 and 1.1 in
the PHT and non-PHT groups (p = 0.042). An MPA/DA ratio of 1.8 carried a positive likelihood ratio (LR+) of 7.5
with a sensitivity of 66.67%, specificity of 91%, positive predictive value (PPV) of 88%, and negative predictive value
(NPV) of 73.21%.ConclusionsThe MPA/DA ratio > 1.8 suggests PHT in children and may lead to the avoidance of invasive cardiac
catheterization particularly in non-CHD patients.

Published: March 2021

IntroductionThe aim of study is to identify the frequency of acute complications and imaging findings at gastro-intestinal transit (GI) and computerised tomography (CT) in a group of obese patients who developed clinical suspicion of acute complications (painful and meteoric abdomen, nausea, vomiting, fever, intestinal blockage) in post bariatric surgery.Material and methodsWe retrospectively review 954 obese patients who underwent bariatric surgery between 2013 and 2019. The study included 72 patients who developed clinical suspicion of acute complications (painful and meteoric abdomen, nausea, vomiting, fever, intestinal blockage) within 6 days of bariatric surgery of sleeve gastrectomy, gastric banding, gastric bypass with Roux loop confirmed by CT, and who underwent a gastrointestinal transit before the CT examination.ResultsGI exam allowed visualisation of 58% of complications. Analysing the data for each surgical technique, 46 post-operative complications were found involve gastric banding. The most frequent was bandage migration (26 cases, 56 %), identified in all cases at GI transit and then confirmed on CT.ConclusionsThe study suggests that CT should be used to clarify all doubtful or clinically discordant GI transit exam results. The participation of a radiologist in qualification and post-operative evaluation is important for bariatric surgery patients.

Secara spesifik tulisan ini bertujuan untuk menganalisis tingkat partisipasi stakeholder dalam peningkatan Indeks Desa Mandiri (IDM) di Kabupaten Sambas. Penelitian yang dilaksanakan antara Agustus 2019-Desember 2019 ini mengambil lokasi pada 4 (empat) desa yang termasuk dalam prioritas peningkatan status kemandirian desa di Kabupaten Sambas tahun 2020. Desa yang dimaksud yakni: Desa Sempalai Sebedang, Kecamatan Sebawi; Desa Durian, Kecamatan Sambas; Desa Sumber Harapan, Kecamatan Sambas; dan Desa Sebubus, Kecamatan Paloh. Hasil penelitian yang berciri kuantitatif ini menujukkan bahwa: pertama, tingkat partisipasi masyarakat umumnya tergolong “kuat” dan “sangat kuat”. Namun, kesediaan masyarakat untuk memberikan materi dalam rangka mendukung pembangunan desa masuk dalam ketegori “cukup”. Hal itu karena mereka menilai pendanaan di desa saat ini sudah cukup tersedia utamanya bersumber dari DD dan ADD; kedua, Tingkat partisipasi pemerintah tergolong “kuat” dan “sangat kuat”. Artinya indikator seperti penyiapan regulasi, keterlibatan pemerintah dalam penyusunan program, pendampingan dalam pelaksaan pembangunan, evaluasi menyangkut audit pemanfaatan DD dan ADD, serta pemanfaatan hasil pembangunan telah sesuai dengan yang diharapkan. Akan tetapi, indikator seperti sejauh mana kemampuan pemerintah untuk membuka akses kerjasama dengan investor dalam mengelola potensi di Desa masih perlu ditingkatkan atau dalam kategori “cukup”; dan ketiga, tingkat partisipasi private sector secara umum masih tergolong “lemah” dan “cukup”. Mulai dari tahapan perencanaan hingga pemanfaatan hasil tingkat partisipasi private sector masih perlu ditingkatkan. Responden menilai CSR yang tersedia belum dirasakan dampaknya hingga ke tingkat desa.

Kegiatan pembelajaran abad saat ini menuntut pendidik dalam melakukan evalausi secara mendalam tentang pelaksanaan pembelajaran yang dilakukan di sekolah. Kegiatan belajar mengajar sudah seharusnya dilaksanakan lebih mempertimbangkan kepentingan peserta didik dan berorientasi pada keberhasislan pembelajaran. Mata Pelajaran geografi merupakan rumpun pelajaran Ilmu Pengetahuan Sosial (IPS). Pada mata pelajaran ini banyak yang menganggap bahwa belajar IPS dalam hal ini termasuk geografi identik terhadap pembelajaran yang monoton terhadap hapalan, sehingga membosankan bagi siswa, apalagi dewasa ini siswa hanya menganggap bahwa mata pelajaran rumpun IPS kurang penting dibandingkan dengan rumpun lainya yang lebih cendrung menyenangkan. Dengan diterapkannya Kurikulum 2013 dalam proses pembelajaran di sekolah, menuntut guru untuk bisa mengembangkan model pembelajaran yang bisa membuat siswa untuk berpikir kritis, aktif dan mampu mendorong siswa untuk menemukan dan mengkonstruksi pikiran mereka berdasarkan materi yang diberikan. Salah satu model pembelajaran yang bisa diterapkan oleh guru untuk mencapai hal tersebut adalah dengan Model Pembelajaran Cooperative Script.

Published: March 2021

Abstract. To mitigate the impacts of the pandemic of coronavirus disease 2019 (COVID-19), the Indian government implemented lockdown measures on 24 March 2020, which prohibited unnecessary anthropogenic activities, thus leading to a significant reduction in emissions. To investigate the impacts of this lockdown measure on air quality in India, we used the Community Multi-Scale Air Quality (CMAQ) model to estimate the changes of key air pollutants. From pre-lockdown to lockdown periods, improved air quality is observed in India, indicated by the lower key pollutant levels such as PM2.5 (−26 %), maximum daily 8 h average ozone (MDA8 O3) (−11 %), NO2 (−50 %), and SO2 (−14 %). In addition, changes in these pollutants show distinct spatial variations with the more important decrease in northern and western India. During the lockdown, our results illustrate that such emission reductions play a positive role in the improvement of air quality. Significant reductions of PM2.5 concentration and its major components are predicted, especially for secondary inorganic aerosols that are up to 92 %, 57 %, and
79 % for nitrate (NO3-), sulfate (SO42-), and ammonium
(NH4+), respectively. On average, the MDA8 O3 also decreases
15 % during the lockdown period although it increases slightly in some VOC-limited urban locations, which is mainly due to the more significant reduction of NOx than VOCs. More aggressive and localized emission control strategies should be implemented in India to mitigate air pollution in the future.
Cloud droplet diffusional growth in homogeneous isotropic turbulence: bin microphysics versus Lagrangian super-droplet simulations
Authors: Grabowski Wojciech W. , Thomas Lois 
Published: March 2021

Abstract. The increase in the spectral width of an initially monodisperse
population of cloud droplets in homogeneous isotropic turbulence is
investigated by applying a finite-difference fluid flow model combined with
either Eulerian bin microphysics or a Lagrangian particle-based scheme. The
turbulence is forced applying a variant of the so-called linear forcing
method that maintains the mean turbulent kinetic energy (TKE) and the TKE
partitioning between velocity components. The latter is important for
maintaining the quasi-steady forcing of the supersaturation fluctuations
that drive the increase in the spectral width. We apply a large
computational domain (643 m3), one of the domains considered in
Thomas et al. (2020). The simulations apply 1 m grid length and are in the
spirit of the implicit large eddy simulation (ILES), that is, with
small-scale dissipation provided by the model numerics. This is in contrast
to the scaled-up direct numerical simulation (DNS) applied in Thomas et al. (2020). Two TKE intensities and three different droplet concentrations are
considered. Analytic solutions derived in Sardina et al. (2015), valid for
the case when the turbulence integral timescale is much larger than the
droplet phase relaxation timescale, are used to guide the comparison
between the two microphysics simulation techniques. The Lagrangian approach
reproduces the scalings relatively well. Representing the spectral width
increase in time is more challenging for the bin microphysics because
appropriately high resolution in the bin space is needed. The bin width of
0.5 µm is only sufficient for the lowest droplet concentration (26 cm−3). For the highest droplet concentration (650 cm−3), an order of
magnitude smaller bin size is barely sufficient. The scalings are not
expected to be valid for the lowest droplet concentration and the high-TKE
case, and the two microphysics schemes represent similar departures.
Finally, because the fluid flow is the same for all simulations featuring
either low or high TKE, one can compare point-by-point simulation results.
Such a comparison shows very close temperature and water vapor
point-by-point values across the computational domain and larger
differences between simulated mean droplet radii and spectral width. The
latter are explained by fundamental differences in the two simulation
methodologies, numerical diffusion in the Eulerian bin approach and a relatively small number of Lagrangian particles that are used in the
particle-based microphysics.

Estratégias de intervenção, no âmbito da educação alimentar e nutricional, podem contribuir para melhoria do padrão de consumo alimentar e estado nutricional de mulheres no climatério, resultando em benefícios a saúde e qualidade de vida. O objetivo do estudo foi avaliar o impacto de uma intervenção nutricional com 2 meses de duração, baseada em estratégias de educação alimentar e nutricional, no estado nutricional, risco cardiovascular, sintomas do climatério, consumo alimentar e no estilo de vida de mulheres adultas. Trata-se de um estudo quase experimental. Coletaram-se dados, pré e pós intervenção, relacionados ao estado nutricional (peso, altura, índice de massa corporal (IMC) e circunferência da cintura (CC)), estilo de vida, satisfação e padrão de peso corporal e frequência de consumo alimentar. Os sintomas do climatério foram avaliados através do Menopause Rating Scale (MRS). Os dados foram analisados no Programa Statistical Package for Social Science (SPSS). Totalizaram-se 16 mulheres, com idade média 54±5,24 anos, sendo que 62,5% referiram aumento do peso nos últimos anos, e 75% manifestaram insatisfação corporal. Houve redução significativa da CC (p=0,006) e da classificação do IMC (p=0,046), do pré para o pós intervenção. Verificou-se aumento na frequência de ingestão de produtos lácteos, ovos, feijão, grãos, e redução do pão branco. Quanto ao estilo de vida e sintomas de climatério, não foram observadas mudanças significativas. A intervenção nutricional com 2 meses de duração mostrou impacto positivo em hábitos de consumo alimentar e estado nutricional de mulheres em fase de climatério.

Com o aumento da expectativa de vida, houve também o aumento da procura dos pacientes edêntulos por uma forma reabilitadora que lhes proporcione maior eficiência mastigatória. Sendo assim, as sobredentaduras sobre implantes utilizando sistemas de encaixe representam modalidade protética mucossuportada e implantorretida que possibilita maior segurança, estabilidade e estética, além de apresentarem menor custo e facilidade para higienização. Internacionalmente, dois implantes são considerados adequados para manter uma overdenture nas mandíbulas desdentadas. No entanto, para muitos pacientes a instalação de dois implantes pode representar um procedimento invasivo e oneroso. Por meio do relato de um caso clínico e da literatura consultada, o presente trabalho mostra que a inserção de um único implante na porção central da mandíbula pode estabilizar a prótese total e melhorar a qualidade de vida e a função mastigatória da saúde bucal. Paciente masculino, 65 anos de idade, relatava falta de estabilidade da prótese total inferior convencional, confeccionada há vários anos. O tratamento proposto foi a instalação de implante único em sínfise mandibular e posterior confecção de novas próteses totais. Uma fixação com pilar tipo o’ring e matriz ativada por parafuso foi usada para manter a sobredentadura inferior. Os resultados clínicos iniciais são promissores, sendo que o paciente do caso em questão relata melhoria na mastigação, estabilidade e função da prótese retida por implante único. No entanto, antes que esse método possa ser recomendado para aplicação clínica geral, são necessários resultados de estudos clínicos longitudinais.

Published: March 2021

O presente artigo centra-se no movimento de produção de significados relacionados ao Pensamento Algébrico. A investigação foi realizada ao longo do ano letivo de 2017 em uma sala de aula de um primeiro ano do Ensino Fundamental — que atende crianças de 6 anos de idade — composta por 26 alunos de uma escola municipal no interior do estado de São Paulo, Brasil. Para a documentação da pesquisa, as aulas da professora-pesquisadora foram videogravadas e serviram de apoio para a escrita de narrativas pedagógicas. Nestas, realiza-se a análise microgenética orientada para os indícios que permitem a interpretação dos episódios observados, possibilitando a aproximação com os processos de desenvolvimento do Pensamento Algébrico dos alunos. A análise aponta indícios de que os estudantes do primeiro ano do Ensino Fundamental, engajados numa cultura social de sala de aula de Matemática, pautada na problematização, na qual são protagonistas do próprio processo de aprendizagem, são capazes de generalizar o padrão da sequência por meio da linguagem materna.
