Published: January 2020

Indonesia is included in the group of countries with a high prevalence of stunting (30-39%) where this prevalence increased from 36.8% in 2007 to 37.2% in 2013. According to UNICEF, the indirect factor causing stunting is parenting (ASI-Exclusive and ASI Complementary Foods/ MP-ASI) are not good. Several studies have suggested that nutritional problems in infants and children are caused by inappropriate breastfeeding and MP-ASI habits. Supplementary feeding for ASI 6-12 months of age is often a problem for families, generally families choose fast food, while self-cooking takes longer, this also occurs in the people of the Kotabaru sub-district area so education needs to be done to mothers who have babies less than 6 months old so they can prepare the right MP-ASI for their children later.

Published: January 2020

Apresenta-se uma proposta didática para o ensino de Astronomia por meio da observação de estrelas variáveis, cujo brilho se altera com o passar do tempo. Aborda-se, em particular, o monitoramento de cefeidas clássicas, as quais exibem modificações regulares na intensidade da luz emitida em razão de efetuarem pulsações periódicas, com seu raio aumentando e diminuindo de maneira cíclica. Discute-se a relação existente entre o período de oscilação e a luminosidade de uma cefeida clássica, mostrando como esta propriedade faculta a determinação do quão afastada a estrela se encontra. Salienta-se a importância histórica e atual da observação de cefeidas clássicas para se estimar distâncias no Universo, com implicações para a formulação de modelos cosmológicos. Descreve-se uma sequência didática relacionada ao tema, estruturada em três momentos pedagógicos, englobando uma problematização inicial, a organização do conhecimento e a sistematização do conhecimento. Exemplifica-se esta proposta considerando-se o caso de ℓ Carinae, cefeida clássica suficientemente brilhante para ser investigada a olho nu.

VISUALIZAÇÃO E UMA AVALIAÇÃO DAS CONCEPÇÕES PRÉVIAS DE ALUNOS DO ENSINO SUPERIOR SOBRE AS ESTAÇÕES DO ANO
Authors: Fagundes Adriano Luiz , Silva Tatiana Da , Barroso Marta Feijó
Published: January 2020

Neste trabalho são investigadas as concepções prévias sobre as estações do ano apresentadas por 961 alunos de uma disciplina de introdução à Física do ensino superior. São analisadas 3 questões de um pré-teste que foi aplicado em 8 semestres seguidos entre 2013 e 2016. A partir de uma perspectiva teórica que busca entender o papel da visualização no Ensino de Ciências, busca-se analisar a maneira como os alunos associam (ou não) o modelo orbital adotado e as suas respectivas explicações para as estações do ano. O instrumento de coleta de dados utilizado permite que sejam encontrados indicativos sobre essa associação. Os resultados indicam que a maioria dos estudantes tem uma visão equivocada sobre a forma do movimento orbital da Terra, o que associado às suas justificativas para a existência das estações se torna inconsistente. Um grupo muito pequeno deste universo, 55 (6%) alunos, consegue apresentar uma explicação coerente em termos dessa mudança de perspectiva.

Este artigo tem, como objetivo, investigar e analisar as concepções sobre as fases da Lua. Para tal, investigou-se um grupo de 39 alunos do Ensino Fundamental II (8ºs anos) de uma escola pública da região Oeste do Paraná. A abordagem foi de cariz qualitativo, focada na análise de conteúdo, e constituída pelas seguintes etapas: a) revisão de literatura e mapeamento acerca das concepções alternativas; b) elaboração e aplicação de um questionário sobre as fases da Lua; e c) análise das concepções dos alunos. Os resultados apontam que a maioria dos alunos não compreende os movimentos de translação e rotação da Terra e da Lua, sendo que apenas 10,3% conseguiram identificar e nomear as fases da Lua no contexto da representação por desenho do fenômeno no sistema Sol-Terra-Lua. Além disso, apareceram as concepções de que a Lua sempre está oposta ao Sol e que suas fases são causadas pela projeção da sombra terrestre. Nesse sentido, entende-se que seja necessária uma revisão nas estratégias de ensino de tais conteúdos com o intuito de transformar a realidade da sala de aula e possibilitar a aprendizagem dos alunos.

Using antibiotic impregnated cement is an important mean to treat and prevent periprostetic joint infections. This complication requires for treatment important financial and technical resources. Adding antibiotics to orthopaedic cement may alter its mechanical properties with possible reduced time of prosthesis survival rate. This study analyze the mechanical properties of cement mixed with antibiotics in the operation room, which helps reducing costs and permit a more specific antibiotic local therapy. All tested antibiotics used in this study does not change the mechanical behavior of the orthopaedic cement when mixed in therapeutic doses, all alterations seems to be at a level below clinical significance. Mixing antibiotics in Orthopedic cement leads to minor decrease of the mechanical properties for cefazolin, cefuroxime, ceftazidime, meropenem and vancomycin and a mechanical significant decrease for gentamicin and clindamycin.

In this paper, optimum hot formation processing parameters for 31VMn12 steel were established, the torsion deformation of 31VMn12 steel was investigated at temperatures from 900, 1000, 11000C and strain rates from 0.05 s-1 to 3 s. -1. There were studied the structural aspects of materials, in microstructures by electronic microscopy. The stress level decreases with increasing deformation temperature and decreasing strain rate, which can be represented by a Zenner-Hollomon parameter. The mathematical model presented in the paper describes the relationship of tension strain, voltage and temperature coefficient 31VMn12 steel at high temperatures. The stress-strain curves determined by the torsion test allowed the calculation of the Zenner-Hollomon parameter corresponding to the maximum stress. By using this parameter has established a set of equations that reproduce completely stress-strain curve, including the hardening, the restoration and dynamic recrystallization area. Comparisons were made between the experimental results and the predicted and confirmed that constitutive equations developed can be used for mathematical modelling and other attempts (forging, compression) and other types of steel.

Published: January 2020

In the paper it is presented a new Euler - Bernoulli theory based on an assymetrical distribution of strains towards the median plane, the area subjected to compression has a transversal stretching, while the area subjected to tensile has a transversal contraction. This theory takes into account the transversal contraction factors and consequently the eigenpulsations of bars vibrations with rectangular section depend on the ratio between the bars width and thickness. This theory is experimentally verified for Dammar based composite bars reinforced with cotton, flax, silk and hemp fibers. For the considered bars, we have experimentally determined the eigen frequencies and the damping factor values.

Extending of the welding application field by high frequency currents of the thermoplastic polymers requires the full knowledge of the physical parameters which characterize the joining process of the welded joint. Since these engineering materials are extremely sensitive to temperature variations, the present paper highlights the role of the thermal gradient in obtaining of some welded joints with high mechanical strength and free from continuity defects. Regarding this, it is demonstrated that increasing the thickness of the polyvinyl chloride films, from 0.4 to 1 mm, the heat effect in the contact area of the electrodes is kept and the welding process has a high stability. For a well-run welding process is obtained a uniform distribution of the molten material in the joint area with positive impact on the breaking force values.

Obstructive sleep apnea syndrome (OSAS) in children is characterized by recurrent events of partial or complete upper airway obstruction during sleep. Functional orthopedics has been used for patients who have OSAS and craniofacial anomalies because they change the mandible posture forwards, improving the respiratory function. In present, much attention is accorded to the relationship between respiratory function and facial morphology. This study combines the cephalometric measurements and cardio-respiratory polygraphy, in order to analyze the effects of a modified functional Twin Block polymeric appliance on respiratory variables in OSAS patients. The chief complaints of the included in study patients was the crooked teeth and the teasing about their smile. Pretreatment facial photographs show labial position of anterior teeth, gummy smile, a large overjet, incompetent lips and retrognathic mandible. The patients underwent overnight cardio-respiratory polygraphic tests in the same Sleep Laboratory, before and after mandibular advancement device treatment. At the end of the orthopedic treatment phase, the beneficial result of this study was the mandible correction, the maxilla restrained, over jet decreased, improving the facial profile and reintegration of the patient in the school social environment. The education of the parents and of the small patients to recognize the symptoms of sleep apnea and to apply the available effective treatments with a positive social impact on self-esteem and which recovers the facial aesthetics and functionality is a stringent necessity.

Palpebral ptosis is a condition caused by different congenital and acquired pathologies. Seeing difficulty due to the visual field obstruction, prefrontal headaches due to chronic use of the frontalis muscle in an attempt to lift the eyelids and cosmetic deformity are the main complaints of the patients. The surgical correction of the ptosis can be challenging. According to the preoperative evaluation, the most appropriate technique should be used to maximize the postoperator result. We describe a new surgical approach for severe upper eyelids acquired ptosis consisting in reanimation of both eyelids by using the neighboring active muscle. We considered the patient a good candidate for the new surgical approach we introduce as one time operative procedure. The result was a normal palpebral fissure for both eyes. The advantage of this approach consists in performing one time surgery followed by immediate postoperative mobilization of the upper eyelids which determine the recovery of the upper lids motility by further self-control.

Published: January 2020

Patients with occupational lung diseases (OLD) may present respiratory functional impairment, exertional dyspnea and decreased exercise tolerance. These factors lead to reduced daily physical activity, social isolation, decreased quality of life (QoL) and depression. Assessment of respiratory functional status in patients with OLD in correlation with the presence of anxiety and depression and the quality of life in patients with OLD, as extrapulmonary comorbidities. In patients with diagnosed OLD, the following parameters were evaluated: pulmonary function tests (FEV1, FVC), anxiety and depression with Hospital Anxiety and Depression Scale (HADS), and QoL by St George Respiratory Questionnaire (SGRQ). 46 non-smoking patients (9 females) were included in this study: occupational asthma (10), occupational COPD (20), pneumoconiosis (16). Mean aged 58.98�11.84SD years old. Anxiety and depression were present in 35 patients (76.08%). Mean HADS score was 14.3 points�7.25SD, and a severe psychological impairment (HADS ] 16) was found in 16 cases (34.8%). The highest incidence of anxiety and depression was found in COPD (85%, mean HADS score 16.05 points�8.18SD), followed by pneumoconiosis (75%, mean HADS 13.5 points�6.87SD) and OA (60%, mean HADS score 12.2 points�5.45SD). The QoL was affected in all patients, with a mean SGRQ score of 52.7 points�16.1SD; the most affected was the activity domain. In patients with OLD, extrapulmonary manifestations may be encountered, such as anxiety, depression and ultimately impaired QoL. This may indicate that treatment of these patients should be multidisciplinary, including psychosocial support.

Published: January 2020

The liver segmentation is mainly determined by the intraparenchymatous distribution of the vascular and ductal hepatic elements; from this, the hepatic portal vein (HPV), is the most important afferent element. The lateral branches (LBrs) are serving left lateral division (LLD) of the liver and present a moderate morphological variability. On a total of 160 pieces of liver corrosion casts, one examined the intraparenchymal distribution of portal LBrs and the segmentation of LLD. Regarding the intraparenchymal distribution of the portal branches in the LLD of the liver, we showed two distinct morphological types: Type I (89.375% of cases) in which from the ombilical part of the left branch arise two LBrs; Type II (10.25% of cases) in which from the ombilical part of the left branch arise three LBrs. Knowledge of these morphological types of portal LBrs is important for clinical and surgical practice.

The spectroscopic and photochemical properties of polyurethane coumarine (PUC) in solid state were investigated at room temperature under once-photon excitation. One photon induced photocycloaddition of PUC was investigated and the AFM and spectroscopic FTIR analysis confirmed dimer formation. The AFM analysis shows that the fotodimerization process occurs at the surface of polymer films. The polyurethane coumarine film on CaF2 unirradiated and irradiated underline both the fotodimerization of the polymer films as well as the photoclevage of the polyurethane coumarin.

Published: January 2020

Possible causes of microleakage and microfractures of dental fillings are often in the center of many academic research and investigations. Some authors found that one important cause of microleakage is the contraction/ shrinkage of the filling materials during polymerization. The purpose of this study is to demonstrate that microcracks and consequent microleakage is influenced by mechanical stresses occurring inside of dental filling materials and at the interface of the dental cavities and dental filling materials. We also tried to evaluate the deformation of some dental filling material types during mechanical loading. Cylindrical specimens were made of different types of dental filling materials, namely microhybrid composites and glass ionomer cement. Some extracted teeth were prepared with class II cavities, and filled. The lateral swelling of the tested specimens and the deformation of the filled teeth during vertical axial loading was measured with an optical method, ESPI/ Shearography.Of the tested specimen, the least deformable dental filling materials were the composite materials. During occlusal vertical loading of the filled teeth, there were found that mechanical stresses were different inside of the filling material than inside of the walls of the dental tissues, mechanical stressed being concentrated at the restoration interface. The ESPI/Shearography meth ode proved to be very useful for investigation in this field. Due to mechanical stresses accumulating at the interface of the dental filling material and the walls of the dental cavity, it is possible that later microcracks to appear due to masticatory forces.
