Published: October 2022

A incontinência urinária consiste em uma questão de saúde pública que afeta as mulheres idosas, no entanto a maior parte da população idosa desconhece o papel da fisioterapia na melhora dessa condição. Esse estudo teve por objetivo investigar o nível de conhecimento sobre a incontinência urinária (IU) e o tratamento fisioterapêutico entre mulheres idosas.  Foi um estudo exploratório e quantitativo com mulheres com idade igual ou superior a 60 anos por meio de formulário eletrônico após divulgação e convite em redes socais. A amostragem, portanto, foi por acessibilidade e conveniência, e as voluntárias responderam questões referentes a características sociodemográficas, situação de saúde, hábitos de vida e dados obstétricos; e o questionário ‘Incontinence Quiz’ que possui perguntas acerca do conhecimento sobre a Incontinência Urinária e Tratamento Fisioterapêutico. Os dados quantitativos foram avaliados por meio da estatística descritiva e inferencial, sendo apresentados em tabelas para melhor delineamento dos resultados. A prevalência de idosas incontinentes do estudo foi de 38,2%, o teste de qui-quadrado apontou associação significativa entre ter IU e número de partos (p<0,001), e entre ter IU e cirurgias ginecológicas (p<0,000). 96,2% das idosas investigadas não procuraram atendimento fisioterapêutico, enquanto que 20,3% destacaram a falta de conhecimento como principal barreira para a busca do serviço de saúde. O público idoso feminino apresentou um breve conhecimento sobre os fatores que influenciam e interferem na IU, assim como, do tratamento fisioterapêutico.

Published: October 2022

Os tumores de ovário são raros na infância, porém devem ser considerados em pacientes femininas de 0-19 anos com dor em região hipogástrica e com massa abdominal. Esses podem ser malignos ou benignos, sendo os malignos responsáveis por cerca de 1% de todos os cânceres pediátricos. A sintomatologia é muito semelhante entre os dois tipos, necessitando investigar cada caso para estabelecer um diagnóstico correto. Esse é feito através de exame físico associado a exames de imagem e laboratoriais, com o tratamento sendo individualizado. Esse estudo tem como objetivo avaliar os tumores ovarianos que acometem a faixa etária pediátrica e adolescência, suas manifestações clínicas e características patológicas, além de observar o tratamento proposto para cada caso e a evolução da doença em um centro de referência em oncologia pediátrica do Oeste do Paraná. Para isso, analisou-se prontuários eletrônicos do Hospital do Câncer de Cascavel, do período de janeiro de 2000 a junho de 2021. Através desse pode-se observar que o tumor de ovário necessita de atenção às manifestações clínicas, exigindo investigação para correto diagnóstico através de exames de imagem e marcadores hormonais, pois é essencial um diagnóstico precoce para melhor prognóstico, aumentando a sobrevida e qualidade de vida das pacientes acometidas.

Published: October 2022

As ferramentas da qualidade podem auxiliar as empresas a crescer, tornando-se mais rentáveis através do fornecimento de produtos ou serviços de melhor qualidade. O objetivo desta pesquisa foi realizar um estudo de caso em uma unidade de alimentação e nutrição (UAN) localizada no estado de Minas Gerais, implementando o uso de três ferramentas da qualidade, nomeadamente: análise de Pareto, diagrama de Ishikawa e método 5W1H com o propósito de obter um melhor controle de custos. Neste sentido, a metodologia escolhida foi a pesquisa qualitativa e a coleta de dados para este estudo se deu por meio de relatório extraído do software de gerenciamento do negócio utilizado pela empresa. Para apuração do custo dos produtos alimentícios utilizaram-se as suas próprias notas fiscais. Após a construção da curva ABC foi possível determinar que as matérias-primas mais caras foram carnes, legumes e folhosos. A partir desses resultados foram elaborados dois diagramas de Ishikawa, para identificação das possíveis causas que levaram ao aumento dos gastos com os produtos mencionados. Assim, foi elaborado dois planos de ações através da metodologia 5W1H. Após a implantação das ações a média de gastos com a compra de carnes reduziu para R$ 76.207,92 e a média de gastos com a compra de legumes e folhosos reduziu para R$ 35.605,03, uma diminuição de 5,79% e 11,69% respectivamente. Pode-se concluir que tais reduções de custos foram satisfatórias para a organização, justificando importância da aplicabilidade das ferramentas da qualidade para o aprimoramento dos processos em uma UAN.

Authors: Padilha Aline Lopes , Alves Filho José Roberto
Published: October 2022

Para confirmar a importância dos profissionais farmacêuticos no tratamento do diabetes, o objetivo deste estudo é identificar a literatura relevante, os cuidados farmacêuticos prestados aos pacientes com diabetes tipo 2. Trata -se de uma revisão integrativa da literatura utilizando fontes de dados como Scielo, Pubmed e Lilacs. A Diabetes Mellitus tipo 2 é uma doença metabólica que tem vindo a aumentar nos últimos anos devido ao estilo de vida sedentária que muitas pessoas têm adotado. Além de uma dieta inadequada, esse grupo populacional deve fazer uso de hipoglicemiantes orais ou insulina para manter seus níveis de glicose dentro dos limites normais. O farmacêutico é um profissional treinado que pode aconselhar sobre tratamentos farmacêuticos e não farmacêuticos, bem como todas as interações medicamentosas. Houve o entendimento de que é essencial que o cuidado farmaceutico seja realizado de forma contínua aos  pacientes diabéticos, pois muitos deles desenvolvem doenças secundárias relacionadas ao uso inadequado de medicamentos, por não apresentarem respostas farmacológicas adequadas ou apresentarem reações adversas a medicamentos.

Authors: Lima Eder Joacir de , Cintra Daniel Dunck , Campos Denise Caldas , Moraes Devacir Vaz de
Published: October 2022

A modelagem matemática é uma tendência de ensino-aprendizagem que pode ser utilizada por professores de matemática que buscam a ruptura com o ensino tradicional. Esse tipo de abordagem quando utilizado, não consiste apenas em analisar problemas do cotidiano, transcrevê-los em linguagem matemática e resolvê-los. É um processo no qual a partir dos modelos podem ser definidas estratégias de ação dos alunos sobre sua realidade. Para isso, é importante que os dados utilizados para elaboração dos modelos venham do cotidiano dos alunos, para que, a partir do modelo construído, sejam retiradas informações importantes que permitam a tomada de decisões para interferência na realidade. O objetivo desse artigo é apresentar uma proposta de atividade de modelagem matemática, fundamentado na educação matemática crítica, que possa contribuir não apenas para o ensino de função linear, como também para o desenvolvimento do pensamento crítico e reflexivo dos estudantes acerca do desperdício e da importância do uso racional da água em nossas residências. Trata-se de uma pesquisa bibliográfica, que apresenta e discute relações entre educação matemática crítica, e modelagem matemática, dentro de uma proposta ainda em âmbito teórico, mas, que pode se desdobrar, posteriormente, em pesquisas de âmbito mais prático e experimental.
Diversity in habitat use by the East Asian fourfinger threadfin Eleutheronema rhadinum revealed by otolith Sr:Ca and Ba:Ca profiles
Authors: Zhang S , Li M , Zhu J , Xu S , Chen Z
Published: October 2022

Determining the movement and migration patterns of fish between different environments is crucial for understanding the distribution of fish populations and the ecological mechanisms underlying their spatial dynamics. This study is the first to employ otolith Sr:Ca and Ba:Ca profiles to elucidate habitat use by the commercially valuable estuarine species Eleutheronema rhadinum. Age 1+ fish were present in samples from the East China Sea and South China Sea, caught off China in October to December of 2019. Characterization of both otolith element profiles through a quantitative approach suggested migration plasticity for E. rhadinum, especially during the first year. However, the Ba:Ca profile revealed a more distinct pattern of habitat use compared with the Sr:Ca profile, suggesting that the Ba:Ca ratio is more appropriate for life-history reconstruction of this species. Most individuals appeared to be estuary-dependent, with some appearing to have entered fresh water for a short time during their first year of life. After their first winter, individuals tended to move into coastal waters, and most apparently overwintered in the marine environment. Knowledge of the diverse life-history strategies of this valuable species at different life stages should be incorporated into future conservation and management efforts.
MANGIFERA INDICA (MANGO) SEED EXTRACT AS A POTENTIAL INHIBITOR ON CARBON STEEL METAL ALLOY CORROSION IN ACID ENVIRONMENT
Authors: IC Ekeke , HC Uzoma , MA Anya ,   Federal University of Technology
Published: October 2022

The inhibitive effect of the ethanolic extract of Mangifera indica seed on the corrosion of carbon steel metal alloy in 0.5 M HCl acidic medium at room temperature was investigated using the gravimetric method. The results showed that, for a given concentration of the extract, the inhibition efficiency decreased with time. The adsorption behavior of the constituents present in Mangifera Indica seed extract onto the carbon steel metal surface was investigated as well. Results indicated that the mode of adsorption of the seed extract on carbon steel metal alloy was best modeled by Langmuir adsorption isotherm with R2 = 0.9604. Again, as the concentration of the inhibitor produced increased, the corrosion rate decreased. Results obtained are therefore indicative of the fact that Mangifera indica seed extract is a good corrosion inhibitor for carbon steel metal alloy in 0.5M HCl acidic medium, though its effect reduced with time under the conditions studied in the present report. And for this reason, it can be used in synergism with another good inhibitor to produce a stronger corrosion inhibitor for the alloy.

An electrolyte for electro chromic device applications was prepared by simple solution cast method. The incorporation of functionalized Alkali metal (Nacl) into poly (vinilydene fluoride-co-hexafluoropropylene): Titanium dioxide (TiO2) in the ratio of 80:5 provided an enhanced dielectrical and structural properties, The casting solution, effects of the solvent and non-solvent in addition of nano scale TiO2 particles and Alkali metal (Nacl) complexes were investigated in this study. After annealing of the PVDF-co-HFP/ TiO2 and AM samples at 1600C, the FTIR study showed many spectral changes including the spectral shift to high wavenumbers and the appearance of new peaks. These spectral changes indicate increasing of crystallinity, strong molecular bonds, and some crystal phase transitions. XRD results showed the change in the crystalline phase of PVdF–co-HFP electrolyte with the addition of surface modified TiO2 and Alkali metal (Nacl). The effect of the TiO2 nanoparticles and Alkali metal (Nacl) surface functionality on the degree of crystallinity of the polymer matrix was analyzed using TGA, scanning electron microscopy (SEM) results the surface morphology and porous nature of the fabricated membrane. The particular polymer electrolyte specimen having 15 wt% Alkali metal (Nacl) exhibited the large values of dielectric constant ' in the low frequency region may be due to an enhanced level of storage of charge carriers at the electrolyte-electrode interface thereby resulting in an increase in the equivalent capacitance. Results show that tends to confirm that the best conducting sample with 15 wt% Alkali metal (Nacl) would possess the maximum number of charge carriers among the five different compositions of NCPE system considered during the present endeavor

Published: October 2022

— Rapid growth of infrastructure to accommodate modern civilization is demanding tall structures in cities. As buildings become taller the problem of their lateral stability and sway needs to be tackled by engineering judgment. Outrigger systems have been successfully applied in reducing the lateral displacement of tall buildings under wind and earthquake forces. Numerous studies have been carried out for determining optimum positions of outriggers in high rise structures; however, effect of earthquake zones and soil types on optimum position of outriggers has not been adequately studied. In the present paper, an analysis of a 70 storied RCC highrise structure provided with and without virtual outrigger system is carried out for determining optimum position of RCC outriggers. The structure has been analyzed to study its behavior under wind and earthquake forces, considering its location in different seismic zones (II, III. IV and V) and also in different types of soils (soft, medium and hard) using “ETAB” software. The virtual outriggers (RCC belt) were provided at seven different levels along the height structure (H/4, 3H/8, H/2, 5H/8, 3H/4, 7H/8 and H) with top level outrigger as fixed and others were varied for their locations. Thus, the structure has been analyzed considering it has been provided with two outriggers at a time, one at the top of structure (H) and the other at a specific level along the heights. Results of the analysis shows lower values for storey displacement, drift and base shear when the structure is considered with one outrigger at top (H) and other at 1/4th height (H/4) for all seismic zones (II, III, IV and V) and all soil conditions (soft, medium and hard). Thus, it is concluded that optimum position of outrigger lies at 1/4th height (H/4) along the height of structure and it goes well in agreement with the values found in literature.

Authors:   The Korean Society of Culture and Convergence, Noh Shihun
Published: October 2022

The purpose of this study was to examine the aspect, function, and meaning of sound or silence through the analysis of the soundscape of death in Seo Kyungsik’s My Pilgrimage to Western Art and The Reaper of Youth. In many cases, the sound associated with these pictures is a human voice, which may be a voice imprinted on the author through experience or a sound printed in the form of a voice in a book he has read. In the two books, the paintings of death the author faces are connected with his memories, and sound or silence is often the medium that makes such connections possible. And at this time, the medium is made in a condensed form to facilitate connection with memory. In the two books, the soundscape of death is far from the four types of ideas Philippe Ariès categorizes about death (“tamed death,” “one’s own death,” “thy death,” and “forbidden death”). Rather, the author tries to remind us that tabooing death is abandoning life by letting us hear the sound of death that surrounds us.
