Medidas de preservação do patrimônio histórico e manutenção das alvenarias tradicionais tornam necessária a análise da estrutura em diferentes aspectos, como geometria, características construtivas e propriedades dos materiais. Essas informações são essenciais na avaliação do estado de conservação dessas construções, detecção de problemas e definição da estratégia de intervenção. Um dos principais promotores da degradação nas estruturas de alvenarias tradicionais é a presença de água. A água pode penetrar, dentre outras formas, por meio de ascensão capilar a partir do solo ou superfícies úmidas, fenômeno mais conhecido como umidade ascensional e que pode comprometer desde a estética até a capacidade resistiva das estruturas. Nesse trabalho, foi utilizado o software WUFI-2D para se realizarem simulações numéricas para avaliar o comportamento higrotérmico de revestimentos argamassados de alvenarias tradicionais, tendo como referência construções históricas do estado do Ceará. Os resultados mostraram que os materiais dos revestimentos e alvenaria devem ser compatíveis quanto a permeabilidade de vapor dos materiais. A incompatibilidade de materiais torna o revestimento uma barreira impermeável que pode contribuir para uma ascensão de frente úmida de até 0,25m, considerando as condições climáticas do ambiente.
Changes in sleep behavior are considered a public health problem, since they interfere with the health of the individual, especially in early childhood, and can impair growth and development. The objective of this study was to evaluate the knowledge about children's sleep in parents of children aged 0 to 24 months. Quasi-experimental study, of the type before and after, with a single group, developed in a pediatric outpatient clinic in northeastern Brazil. Convenience sample of 60 parents of children discharged from the neonatal unit, who represent preliminary data from a larger study. Data collected between November / 2019 and January / 2020, using the CAP survey (Knowledge, Attitude and Practice). A child sleep instrument was used in the pre-test (first time with the parents) and post-test (15 days after the first application). After the pre-test, the parents read an educational booklet containing the information to which they were asked. The knowledge about sleep was assessed including, time, place and sleeping clothes, position in the crib, prevention of sudden infant death syndrome and total sleep time. Scores ≤ 3 represented inadequate knowledge; 4-7 adequate knowledge. Only 5 parents had inadequate knowledge in the pre-test. In the post-test, everyone demonstrated adequate knowledge. The average of points in the pre-test was 4.3, median of 4. In the post-test, the average of points (6.15), median (6). In the pre-test, less correct questions were total sleep time, adequate sleeping position, with 12 and 20 errors, respectively. After the application of the booklet, the question regarding the total sleep time remained with an equal number of errors, however only 7 parents were wrong about the position of the child at the time of sleep. It is concluded that there is a need for guidance to parents on sleep, and it is pertinent to evaluate their previous knowledge, contributing to the strengthening of public policies aimed at children's sleep. Key messages Parents should receive guidance on infant sleep hygiene. Strengthening the promotion of children's sleep by health professionals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
