Authors: Salvalaio Muline Leonardo , Cabral Félix de Sousa Isabela
Published: October 2019

As práticas pedagógicas que levem o aluno a pensar criticamente sobre o meio em que vivem são essenciais dentro do contexto educacional. Aplicamos entrevistas semiestruturadas a nove professores trabalhando na Educação Básica. Nossa pesquisa é de natureza qualitativa, um estudo de caso, conforme definem Ludke e André (1986). Esta pesquisa busca apresentar, e avaliar, respostas de educadores das séries iniciais do Ensino Fundamental de uma escola pública municipal (Vitória – ES) sobre assuntos pertinentes aos seus processos formativos e sobre algumas questões relacionadas à disciplina de Ciências. Nossos resultados indicam que são necessários mais investimentos na formação continuada dos docentes, no intuito de promover um ensino de Ciências que leve para dentro da escola alternativas mais atrativas para encorajar a aprendizagem dos alunos e para que professores e alunos façam uma leitura mais aguçada do seu cotidiano.

Published: October 2019

Este trabalho buscou identificar, na produção científica nacional, evidências sobre a abordagem da educação sexual pela enfermagem no contexto da escola de nível fundamental e médio. Trata-se de estudo de revisão integrativa, sendo os dados coletados na base de dados da Biblioteca Virtual de Saúde, no período de setembro a outubro de 2015, segundo critérios de exclusão e inclusão pré-determinados. O levantamento bibliográfico identificou 191 publicações, sendo a amostra final composta por 13 estudos que atendiam aos critérios de elegibilidade. Foi possível inferir que há uma significativa lacuna de conhecimento a respeito do tema e a falta efetiva de uma integração ou envolvimento do profissional de enfermagem na questão educacional escolar. No entanto, podemos apontar que a enfermagem, na vertente voltada para a educação em saúde, pode contribuir para promover nos adolescentes comportamentos e atitudes responsáveis.
The Indian Origin of Romani people as a Founding Myth in Eastern European Museums
Authors: Sambati Douglas
Published: October 2019

The article analyses three museums – the Muzeum Romské Kultury in Czech Republic, the Muzej Romské Kulture in Serbia, and the Roma Ethnographic Museum in Poland – can be considered as elements of the Romani Nationalism. The main objective is to reflect on how these museums support a broad narrative about a common Indian origin of Gypsy/Romani populations. It is discussed how the aforementioned museums – by means of their exhibitions, websites, events or other any kind of official production – support sets of representations which allow a formation of an umbrella rhetoric about the groups known, taken and self-ascribed as Gypsies and/or Roma. The said rhetoric, then, is able to shelter all different groups within this population in a holistic manner, based on a narrative formed by essentializations, exoticizations and generalizations. The utmost layer of such practices it is an elaboration of a founding myth of their Indian Origins. This paper understands throughout that museums have a role in the process in which the concept of Roma is generalized in an attempt to rewrite and relabel Gypsy memory as a Roma history. Hence, considering the plurality that characterise the Gypsy/Romani people, it was necessary to articulate common aspects – whether truthful or not, is not the target of this article to discuss – which would legitimise this new identity, a Roma identity. This paper relies on the theories about memory, museology, sociomuseology, and the theory of representations.

Published: October 2019

Fundamento: Pacientes com doença valvar aórtica frequentemente apresentam doença renal crônica (DRC). Diminuição da perfusão renal como consequência da redução do débito cardíaco pode contribuir para a disfunção renal neste cenário. Objetivo: Dado o potencial de reversibilidade da hipoperfusão renal após o reparo valvar, este estudo teve o objetivo de analisar o impacto do implante percutâneo de válvula aórtica (TAVI – transcatheter aortic valve implantation) na função renal. Métodos: Foi realizada uma análise retrospectiva de 233 pacientes consecutivos submetidos ao TAVI em um único centro, entre novembro de 2008 e maio de 2016. Três grupos foram avaliados de acordo com a taxa de filtração glomerular estimada (TFGe) basal (mL/min/1,73 m2): Grupo 1 com TFGe ≥ 60; Grupo 2 com 30 ≤ TFGe < 60; e Grupo 3 com TFGe < 30. O TFGe foi analisado nestes três grupos um mês e um ano após o TAVI e calculado usando a fórmula do Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI). Resultados: Os pacientes do Grupo 1 tiveram um declínio progressivo da TFGe um ano após o procedimento TAVI (p < 0,001 vs. pré-TAVI). Nos pacientes do Grupo 2, a média da TFGe aumentou um mês depois do TAVI e continuou crescendo depois de um ano (p = 0,001 vs. pré-TAVI). O mesmo ocorreu no Grupo 3, com a média da TFGe subindo de 24,4 ± 5,1 mL/min/1,73 m2 antes do TAVI para 38,4 ± 18,8 mL/min/1,73 m2 um ano após o TAVI (p = 0,012). Conclusões: Em pacientes com DRC moderada a grave, a função renal melhorou um ano após o procedimento TAVI. Este resultado é provavelmente devido à melhora da perfusão renal pós-procedimento. Acredita-se que, ao avaliar pacientes que possam precisar de TAVI, este ‘efeito de reversibilidade da DRC’ deva ser considerado.

Authors: Narmawan Narmawan , Syahrul Syahrul , Erika Kadek Ayu
Published: October 2019

Background: Diabetes mellitus (DM) is a chronic non-infectious disease with complications such as diabetic foot, which has the potential for amputation if left untreated. Theory of Planned Behavior (TPB) is a behavior-based theory that can be applied to DM patients including foot care to minimize risk. Some studies related to TPB particularly about physical activity and diet have been explored, however, studies on foot care are still lacking.Objective: This study aims to apply the Theory of Planned Behavior (Intentions, Attitudes, Subjective Norms and Behavioral Control) on the patient's foot care.Methods: This was a cross sectional descriptive study. There were 93 patients diagnosed with type 2 DM recruited at 9 public health centers (Puskesmas) using accidental sampling on April 2018. TPB-based foot care questionnaire from the IWGDF (International Working Group on Diabetic Foot) Diabetic Foot guidelines was used. Data were analyzed in the form of frequency distribution.Results: Of the total number of respondents, 25 males and 68 females with average age of 53.05 ± 8.04 years, approximately 87.1% of them have the intention to wear footwear according to size. The majority of patients think that washing feet every day is a form of good and positive practice. They also agreed that the family expects the patient to examine the presence of bone / joint protrusions independently and believes that monitoring the foot deformities performed by other DM patients is very important as well as having control that the patient can check for signs of boils in the legs and there is a high likelihood of blisters / sores if the socks used are not suitable.Conclusion: The majority of respondents have good intentions, positive attitudes, social support and behavioral controls for foot care.

Authors: Ramdan Iwan Muhamad , Sartika Dewi
Published: October 2019

Background: Low back pain (LBP) is a type of musculoskeletal disorder that has a detrimental effect on both workers and business continuity. Weaving activities with handloom are at risk for this disorder.Objective: To analyze the prevalence of LBP among Samarinda sarong’s traditional weavers and its related factors.Methods: A cross sectional study was conducted on 49 traditional weavers of Samarinda Sarong. The instruments included the Owestry low back pain disability questionnaire, rapid entire body assessment (REBA), microtoise staturmeter and stopwatch. Data were analyzed using multiple logistic regressions.Results: The result showed that most of the weavers (92.5%) experienced LBP. Age (p= .000), work experience (p=.000), workload (p=.048) and work posture (p=.000) were significantly associated with LBP, while nutritional status (p=.773) and workload (p= .343) were not associated with LBP. Age and work posture were the most dominant variables affecting LBP.Conclusion: The prevalence of LBP among Samarinda sarong’s traditional weavers was quite high and was strongly influenced by the weavers' age and posture work. In order to improve work posture and reduce the incidence of LBP, it is recommended to modify handlooms (tables and chairs) by following ergonomic rules, reducing workload, work time limitation and adequate rest.
Signatures of a Planet–Planet Impacts Phase in Exoplanetary Systems Hosting Giant Planets
Authors: Frelikh Renata , Jang Hyerin , Murray-Clay Ruth A. , Petrovich Cristobal
Published: October 2019

Exoplanetary systems host giant planets on substantially noncircular, close-in orbits. We propose that these eccentricities arise in a phase of giant impacts, analogous to the final stage of solar system assembly that formed Earth’s Moon. In this scenario, the planets scatter each other and collide, with corresponding mass growth as they merge. We numerically integrate an ensemble of systems with varying total planet mass, allowing for collisional growth, to show that (1) the high-eccentricity giants observed today may have formed preferentially in systems of higher initial total planet mass, and (2) the upper bound on the observed giant planet eccentricity distribution is consistent with planet–planet scattering. We predict that mergers will produce a population of high-mass giant planets between 1 and 8 au from their stars.
Multilayered Kelvin–Helmholtz Instability in the Solar Corona
Authors: Yuan Ding , Shen Yuandeng , Liu Yu , Li Hongbo , Feng Xueshang , Keppens Rony
Published: October 2019

The Kelvin–Helmholtz (KH) instability is commonly found in many astrophysical, laboratory, and space plasmas. It could mix plasma components of different properties and convert dynamic fluid energy from large-scale structure to smaller ones. In this study, we combined the ground-based New Vacuum Solar Telescope (NVST) and the Solar Dynamic Observatories/Atmospheric Imaging Assembly (AIA) to observe the plasma dynamics associated with active region 12673 on 2017 September 9. In this multitemperature view, we identified three adjacent layers of plasma flowing at different speeds, and detected KH instabilities at their interfaces. We could unambiguously track a typical KH vortex and measure its motion. We found that the speed of this vortex suddenly tripled at a certain stage. This acceleration was synchronized with the enhancements in emission measure and average intensity of the 193 Å data. We interpret this as evidence that KH instability triggers plasma heating. The intriguing feature in this event is that the KH instability observed in the NVST channel was nearly complementary to that in the AIA 193 Å. Such a multithermal energy exchange process is easily overlooked in previous studies, as the cold plasma component is usually not visible in the extreme-ultraviolet channels that are only sensitive to high-temperature plasma emissions. Our finding indicates that embedded cold layers could interact with hot plasma as invisible matters. We speculate that this process could occur at a variety of length scales and could contribute to plasma heating.

Published: October 2019

Aggressive behavior is a frequent occurrence in the care of individuals with dementia. In this pilot study, the authors explored the impact of sharing patients’ life histories with staff on four patients’ aggression and interviewed nursing staff and families to determine the impact that developing and learning about the life history had on them. There was some evidence of decrease in aggression among the patients who demonstrated frequent aggressive behavior at baseline. Life history information affected some staff members profoundly, leading toward a greater empathy for the patient. This study demonstrates the feasibility and potential value of using life histories with residents who demonstrate aggressive behavior.
Dressing and Grooming: Preferences of Community-Dwelling Older Adults
Authors: Cohen-Mansfield Jiska , Jensen Barbara
Published: October 2019

This study explored dressing and grooming habits and preferences of older adults. Fifty-eight community-dwelling older persons (mean age = 80 years) in suburban Maryland responded to the Self-maintenance Habits and Preferences in Elderly (SHAPE) questionnaire. There was a large variability in preferences, and all items were very important for at least some of the participants. Women attributed higher levels of importance to dressing and grooming than did men. Importance ratings increased with level of education and were higher for unmarried persons, but were not related to age or need for assistance with instrumental activities of daily living (IADLs). On an individual basis, this information can be used to suggest items for interventions or to structure a personal care environment. Alternately, it can be used in the aggregate as a guideline for designing programs of care to reflect the preferences of a majority of older persons.

EXCERPT

Suffering is everywhere, and when one has passed through the cauldron, a sincere hand and heart survive in the mind as the warmest of memories. Be interested in people, their lives and their families. It is vital that you not feel like a total patient. Hell, we’re all patients in this universe we share now.

~Older Adult Patient, Gene Higgins

Nursing homes are, among other things, a dramatic reminder that cultural attitudes have consequences. It is there that our society’s fear and denial of aging and death play themselves out in end-of-life care of residents. This editorial will examine some of the problems in end-of-life nursing home care and the need for concrete improvements.

Authors: Jenkins Kristi R. , Kabeto Mohammed U. , Fultz Nancy H. , Langa Kenneth M.
Published: October 2019

The authors sought to obtain nationally representative estimates of the time of informal caregiving provided to older adults classified into the four standard Body Mass Index (BMI) classifications. They estimated multivariate regression models using data from the 2000 Health and Retirement Study to determine the weekly hours of informal caregiving for older adults classified into the four standard BMI classifications. In the fully adjusted models, being underweight was associated with receiving significantly more informal care, however, obesity was not associated with more informal care. The implications of these findings are discussed in terms of nursing practice and research to prevent weight loss and frailty.

After the RCF tests, we directly observed the subsurface cracks.
A Modified Energy Method for Equilibrium Structure and Strain Energy of Armchair Single-Walled Carbon Nanotubes
Authors: Gao Ming , Bian Li Chun , Liu Chang , Guo Jiu Ming
Published: October 2019

Based on molecular mechanics, a modified energy model was proposed to study the angular variation and strain energy of armchair carbon nanotubes under stress-free conditions. In this model, the inversion energy term is added to make the calculation more accurate. The results show that the strain energy of armchair carbon nanotubes is more significantly affected by the added energy term under small diameter, especially when the diameter is less than 1 nm. This has a lot to do with the curvature of the tube. As compared with the unmodified model, the strain energy deviation between the two models decreases with the increase of tube diameter, which also verifies the remarkable characteristics of small diameter. At the same time, the angles change of armchair carbon nanotubes was calculated by using the modified model in the stress-free state, which is also quite different from that of the unmodified one in the small diameter.

The effects of Al doping to the thermoelectric properties of ZnO thin films fabricated through ink-jet printing were studied in this paper. Ink-jet printing was used to deposit the Al doped ZnO thin films. A minimum of 50 print cycles was required to obtain continuous film with approximately 9 μm thick thin films. It was possible to obtain high thermoelectric properties of ZnO by controlling the ratios of dopant added and the temperature of the heat treatments.The XRD traces of Al doped ZnO exhibit a polycrystalline hexagonal structure for the wurtzite phase of ZnO. There were no additional phase detected for Al doped ZnO thin films with increasing amount of Al dopants and heat treatment temperature. The results show Al doping had improved the thermoelectric properties of ZnO with an increased in electrical conductivity. The electrical conductivity of pure ZnO thin film (5 S/cm) was enhanced with increasing the dopant to 4wt% Al doped ZnO (114 S/cm). Negative Seebeck values were observed for all the samples that indicated n-type semiconductor. Pure ZnO samples have a measured Seebeck coefficient-17.63 μV/K decreased to-14.35 μV/K with 4 wt% Al doped.

M6C carbides were found to form during short-term creep tests at 600 °C for 1100 h in an 11Cr ferritic/martensitic (F/M) steel with the normalized and tempered condition. The M6C carbides have a face-centered cubic crystal structure, and a metallic element composition of 41-45Fe, 30-33W, 19-21Cr, 3Co/5Ta in atomic pct. The M6C carbides were a dominant phase in the crept steel. δ-ferrite in high-Cr F/M steels may lead to a premature formation of large-sized M6X precipitates during high temperature creep.

This work described the technology of boronizing of titanium Grade2 from the generation of the gas phase directly in a sealed container during the decomposition reactions of the powder saturating medium. With such an implementation of the process in a closed volume, waste gas neutralization devices are not required, since the generation and decomposition of active saturating gases occurs in a closed volume. At saturation of titanium from the gas mixture, titanium borides, titanium nitrides, as well as titanium and chromium carbides can be produced in the coating. The microhardness of the coating is 2800–3200 HV0.1. The thickness of the diffusion coatings in this case can be up to75 microns. It is indicated that diffusion coatings on titanium by this technology should not exceed a thickness of more than 100 microns, and if the thickness of the diffusion coating exceeds 100 microns, the risk of chipping will increase.

Published: October 2019

Zn-Al-Mg alloys with hypoeutectic microstructure were melted through a high frequency induction furnace. The content of aluminum and magnesium in the alloys were between 1% to 2%. Scanning electron microscopy (SEM) was utilized to analyze microstructure and phase, respectively. Effect of alloying element contents on corrosion resistance was studied. Results show that the Zn-Al-Mg alloys are almost covered by primarily solidified Zn rich block phase and fine lamellar binary and ternary eutectic microstructure exist between the Zn rich phase. The corrosion resistance was characterized through electrochemical test which indicates that increasing Al and Mg content in the Zn-Al-Mg alloys decline corrosion current density. For alloys with 1% Al, more magnesium means lower corrosion potential. For alloys with 2% Al, however, more magnesium suggests higher corrosion potential. In Nyquist curves of electrochemical impedance spectroscopy (EIS) test, Warburg impedance portion could be found for all alloys. With increasing alloying elements content in the Zn-Al-Mg alloys, charge transfer resistance in higher frequency remarkably increase, which implies higher corrosion resistance.

DPI Selectively Inhibits Intracellular NADPH Oxidase Activity in Human Neutrophils

Published: October 2019

Neutrophils are capable of producing significant amounts of reactive oxygen species (ROS) by the phagocyte NADPH oxidase, which consists of membrane-bound and cytoplasmic subunits that assemble during activation. Neutrophils harbor two distinct pools of the membrane-localized oxidase components, one expressed in the plasma membrane and one in the membranes of intracellular granules. Assembly of active oxidase at either type of membrane leads to release of extracellular ROS or to the production of ROS inside intracellular compartments, respectively. The cytoplasmic NADPH oxidase subunit p40phox seems selectively critical for the ability to generate intracellular ROS, and the recent characterization of patients with p40phox deficiency implies that selective loss of intracellular neutrophil ROS leads to disease with pronounced hyperinflammatory features, suggesting that these ROS are critical for regulation of inflammation. This study aimed at characterizing two pharmacological NADPH oxidase inhibitors, the newly described GSK2795039 and the widely used diphenyleneiodonium (DPI), focusing on their abilities to inhibit human neutrophil ROS production extra- and intracellularly. Whereas GSK2795039 blocked extra- and intracellular NADPH oxidase activity equally, DPI was found to selectively interfere with intracellular ROS production. Selectivity for the intracellular NADPH oxidase was evident as a lower IC50 value, faster onset, and irreversibility of inhibition. We found no evidence of direct interactions between DPI and p40phox, but the selectivity of DPI confirms that regulation of NADPH oxidase activity in neutrophils differs depending on the subcellular localization of the enzyme. This information may be used to pharmacologically mimic p40phox deficiency and to further our understanding of how intracellular ROS contribute to health and disease.

The objective of this study is to assess the prognostic value regarding 28-day outcome of the quick sequential organ failure assessment (qSOFA) score and the combined score calculated from blood lactate levels + qSOFA (LqSOFA) score in elderly patients initially treated in the Emergency Department (ED) for sepsis due to pneumonia or other chest infections. This is a prospective observational study, conducted at the ED in a Greek University Hospital. Forty-one patients with sepsis due to chest infection were enrolled in the study. All patients were treated in the Resuscitation Room of the ED according to the international treatment protocols for sepsis. The qSOFA score was calculated on admission for all patients, and one point was added in the calculation of the LqSOFA score in patients with blood lactate levels >2 mmol/L. Both the qSOFA and the LqSOFA scores had high sensitivity and specificity in predicting unfavorable outcome in elderly patients with chest infection and sepsis. In the ongoing debate of early diagnosis of sepsis and identification of prognostic indexes of the syndrome, qSOFA score alone or in combination with lactate levels could serve as a reliable predictor of outcome. Large prospective studies are needed to further evaluate the role and prognostic validity of these scores in the ED.

Published: October 2019

Sarcoidosis is a multisystem granulomatous inflammatory disorder frequently affecting the lungs, but also the liver, along with cirrhosis and portal hypertension occurring in less than 1% of the patients. A 56-year-old female presented with dyspnea, abdominal and leg swelling. Physical examination revealed finger clubbing, ascites and pretibial edema. Chest CT revealed diffuse micronodular opacities in both lungs without any enlarged thoracic lymph nodes. PFTs and DLCO/VA were moderately decreased. Transbronchial biopsy revealed non-caseified granulomas compatible with sarcoidosis. Serologic markers for infectious and autoimmune hepatitis were negative. Liver biopsy showed non-caseating granulomas, severe hepatitis and fibrosis. Stool, urinary analysis and antibodies for Schistosoma infection were negative. Final diagnosis was cirrhosis associated with stage III sarcoidosis. We report a case of sarcoidosis complicated by cirrhosis and portal hypertension with finger clubbing. Clinicians should bear in mind that cirrhosis, portal hypertension and clubbing may arise as the initial manifestations of sarcoidosis.
Framing heuristics in inclusive education: The case of Uganda’s preservice teacher education programme
Authors: Nantongo Proscovia S.
Published: October 2019

Background: Recent education-related research has raised concerns about the persistent exclusion of vulnerable learners in Uganda. The Revised Primary Teacher Education Curriculum of 2013 marked an ambitious yet inconclusive attempt to advance the implementation of inclusive education but has encountered deeply entrenched sociocultural exclusionary practices among education experts.Objectives: This study aimed to explicate education practitioners’ interpretations of Uganda’s flagship inclusive education programme in preservice primary teacher education.Method: Drawing on the conceptual vocabulary of frame analysis and the qualitative analysis of individual and group interviews and classroom observations, the interpretations of inclusive education implementation in preservice primary teacher education in Uganda were examined. The participants included policy design experts, curriculum design experts and classroom practitioners.Results: Three main findings emerged. Firstly, interpretations of inclusive education displayed a narrow framing heuristic of inclusive education as a perfunctory, daily practice rather than a pathway for reflective, inclusive pedagogical engagement. Secondly, the heuristic encouraged the treatment of inclusive pedagogy as a ‘label’ under a specific rubric referring to sensory impairments or disabilities – a historical device for sociocultural exclusion. Thirdly, inclusive education was a praxis but was misframed from its original intentions, causing tension and resentment among practitioners. These findings contribute to the debates on the sustainability of inclusive education beyond preservice teacher education.Conclusion: Uganda’s flagship inclusive education programme in preservice primary teacher education was fraught with tensions, ambiguities and an overt, urgent need for change.
