Published: July 2020

O espaço geográfico tem sido objeto de estudo em diversas perspectivas, sendo que a Geografia da Saúde vem ganhando destaque em razão do crescente aumento de doenças que vêm sendo notificadas na esfera global. Nesse sentido, esse processo tem potencializado, por sua vez, novas ferramentas geoinformacionais que auxiliam no estudo, na análise e no mapeamento das doenças ao nível espacial. Diante do exposto, essa pesquisa objetiva realizar o mapeamento de arboviroses no Território de Desenvolvimento Entre Rios, no Estado do Piauí, considerando o recorte temporal de 2012 a 2016, na perspectiva de modelar em ambiente de Sistema de Informação Geográfica (SIG), os setores territoriais que apresentam as maiores incidências no número de casos de dengue. Para tanto, foi necessário estruturar um SIG por meio de um inventário digital, com capacidade de interligar as informações em um banco de dados, permitindo a realização de consultas e a apresentação dos dados na forma de mapas temáticos. Deste modo, foi possível traçar o perfil situacional dos municípios do Território de Desenvolvimento Entre Rios, frente à ocorrência dos arbovírus da dengue. A pesquisa em epígrafe visou o desencadeamento de ações mais efetivas ao nível territorial, a partir do viés de transformar os dados em informação e, consequentemente, em conhecimento.

Governance: conceptual varieties

RESUMO: A governança tem sido objeto de múltiplos estudos recentes nos âmbitos das Ciências Sociais, da Ciência Política, da Administração Pública e das Relações Internacionais. Não obstante, nota-se que esse termo é utilizado com imprecisão. Partindo do pressuposto de que se trata de termo com um grau de indeterminação, o presente artigo, pretende expor os significados já mapeados pela literatura e investigar as relações entre as definições encontradas. Pretende-se, ainda, identificar como as três formas de “conceituar” governança são trabalhadas pelos autores que se debruçaram sobre a questão.

PALAVRAS-CHAVE: Governança. Meta-governança. Conceitos. Definições.

ABSTRACT: Governance has been the subject of many recent studies in the fields of Social Sciences, Political Science, Public Administration and International Relations. Nevertheless, it is noted that this term is used with imprecision. Based on the assumption that it is a term with a degree of indeterminacy, the present article intends to expose the meanings already mapped by the literature and to investigate the relations between the definitions found. It is also intended to identify how the three forms of “conceptualizing” governance are employed by the authors who have studied the question.

Implementasi Pola Pemuridan Yesus Menurut Injil Matius
Authors: Sembiring Johannes
Published: July 2020

Matthew does not emphasize the apostle's understanding of Jesus' disciples in his writings, but instead uses the term "disciple." Matthew, dealing with Jews who are peculiar to discipleship, certainly considers the root importance of the term "disciple", a learner. A person who serves God should be a disciple of Christ, who loves and follows Christ and lives according to the character of the Lord Jesus with all his heart. This is a literature review article that uses descriptive methods. Descriptive study was applied to the pastors of the GPdI session in Jember Regency which numbered 28 people as participants. Research data obtained directly from the field using research instruments in the form of a questionnaire. After analyzing to get answers based on the percentage of participant scores, it can be concluded that the implementation value of Jesus' discipleship pattern according to the Gospel of Matthew among the Pastors of the GPdI Session in Jember district is very high, namely 90.30%. AbstrakMatius tidak menekankan tentang pemahaman rasul pada murid-murid Yesus pada Tulisannya,  akan tetapi menggunakan istilah “murid.” Matius berhadapan dengan orang Yahudi yang khas dengan pemuridan, pasti menganggap penting akar istilah “murid” tersebut, yaitu seorang yang belajar. Seorang yang melayani Tuhan seharusnya adalah seorang murid Kristus, yang mengasihi dan mengikut Kristus serta hidup sesuai karakter Tuhan Yesus dengan sepenuh hati. Ini merupakan artikel kajian literatur yang menggunakan metode deskriptif. Kajian deskriptif diterapkan pada gembala-gembala sidang GPdI se-Kabupaten Jember yang berjumlah 28 orang sebagai partisipan. Data-data penelitian diperoleh secara langsung dari lapangan dengan menggunakan instrument penelitian dalam bentuk angket. Setelah dilakukan analisis untuk mendapatkan jawaban berdasarkan prosentasi skor partisipan, maka dapat disimpulkan bahwa nilai implementasi pola  pemuridan Yesus menurut Injil Matius dikalangan Gembala Sidang GPdI se-kabupaten Jember adalah sangat tinggi, yaitu 90,30%.

Authors: Pasae Yoel , Bulo Lyse , Lande Chrisnovan , Allo Eda Lolo
Published: July 2020

The increasing use of plastic makes plastic waste the number one contributor to environmental damage in the world. The type of plastic that is most often found as waste is Polypropylene (PP). One way to overcome this problem is to convert plastic into liquid oil, which can be used for various purposes in the chemical industry or as an alternative fuel. Pyrolysis is a technology commonly used to convert plastics into liquid oil, and can be done by the public. But the availability of pyrolysis reactors that are easy and safe to operate is something that needs attention. In this research, a pyrolysis reactor with a capacity of 1 kg / batch has been modified from a gas cylinder. The pyrolysis process was carried out at 250°C, 275°C, 300°C, 325°C and 350°C with a reaction time of 120 minutes. The results showed that pyrolysis at 350°C can produce the highest yield of 62.56%. Through testing using Gas Chromatograpy-Mass Spectroscopy it is known that the liquid oil obtained consists of several groups of compounds or derivatives from Hexane, Heptane, Isotridecanol, Dodecana, Cyclohexana, Benzene, Pentane, and Octana.
Modelo bayesiano de producción excedente con autocorrelación serial
Authors: Hernández † Daniel , Rodríguez Julieta
Published: July 2020

Se presenta un modelo simple de producción excedente al que se denomina Modelo de Producción Excedente con Autocorrelación Serial (MPECAS) debido a que considera como único supuesto que la producción excedente presenta correlación serial y no tiene una relación funcional explícita con la biomasa. Su aplicación se logra solo con un índice de abundancia proporcional a una potencia dada de la abundancia media real del recurso y la serie de capturas anuales correspondientes. La estimación de los parámetros del modelo se plantea en un contexto bayesiano utilizando el algoritmo SIR (Sampling Importance Resampling). Se proponen criterios de riesgo sencillos para estimar la Captura Máxima Biológicamente Aceptable (CMBA) y los riesgos asociados a cada nivel de captura hipotética considerada. Se llevó a cabo un ejercicio de simulación para evaluar la capacidad estadística del MPECAS para reproducir la información proporcionada por un modelo operacional de producción excedente de Schaefer considerado como real. Finalmente, se presenta un ejemplo de aplicación con el recurso corvina rubia (Micropogonias furnieri) y se muestran las CMBA para el 5 y 10% de riesgo de disminución de biomasa en el año siguiente al de evaluación calculadas con el modelo de Schaefer y el MPECAS.

Analysis of the Aggregate Heuristic Planning for Planning and Controlling the Amount of Production to Minimize Costs
Authors: Magdalena Riana
Published: July 2020

PT.XYZ is one of the companies engaged in the automotive manufacturing industy, where it produces spare parts for cars, motorcycles and trucks. Along with marketing and producing the products, PT.XYZ continues to implement customer satisfaction and the quality of spare parts produced.Â  The company must anticipate the possibility of production capacity limitations; this must be done as well as possible at the minimum cost. For that, the aggregate heuristic planning is proposed for planning the establishment of a level for production capacity to meet the level of demand obtained from orders with the aim of minimizing total production costs. Aggregate Planning is a process of determining the level of overall production capacity to meet the level of demand obtained from forecasting and order with the aim of minimizing the total cost of production. In this study, three heuristic methods were tried, namely labor control method, subcontracting mixed method, and overtime mixed methods. Based on the results of the study it is known that the subcontracting mixed method is the best method with total aggregate cost of IDR 3,080,689,770, then the labor control method with a total of aggregate cost of IDR 3,080,798,198 and the overtimeÂ  mixedÂ  method, with a totalÂ  aggregate cost ofÂ  IDR 3,081,815,315.Â

Authors: Sukono Sukono , Suryamah Emah , Novinta S Fujika
Published: July 2020

Crude oil is one of the most important energy commodities for various sectors. Changes in crude oil prices will have an impact on oil-related sectors, and even on the stock price index. Therefore, the prediction of crude oil prices needs to be done to avoid the future prices of these non-renewable natural resources to increase dramatically. In this paper, the prediction of crude oil prices is carried out using the Auto-Regressive Integrated Moving Average (ARIMA) and Generalized Auto-Regressive Conditional Heteroscedasticity (GARCH) models. The data used for forecasting are Indonesian Crude Price (ICP) crude oil data for the period January 2005 to November 2012. The results show that the data analyzed follows the ARIMA(1,2,1)-GARCH(0,3) model, and the crude oil price forecast for December 2012 is 105.5528 USD per barrel. The prediction results of crude oil prices are expected to be important information for all sectors related to crude oil.

Published: July 2020

Prerequisite to unlock the full potential of Mg-based materials is to gain control of their degradation properties. Here a proof of concept is presented for an efficient and robust alternative to the data-driven machine learning approaches that are currently on the rise to facilitate the discovery of corrosion modulating agents. The electronic properties of bipyridine were tuned by its substitution with electron donating and electron withdrawing functional groups to regulate the degradation modulators interaction with different ions and the effect on the corrosion inhibition of pure Mg was predicted based on density functional theory calculations. Bipyridine and two of its derivatives were subsequently investigated experimentally to validate the trend predicted by the quantum chemical calculations.
A multifuncionalidade de aliás: valores semânticos em perspectiva funcional
Authors: Ramos Nice Da Silva
Published: July 2020

Este artigo tem por objeto de estudo o elemento linguístico aliás, observado nos diferentes contextos de uso em que é recrutado. Segundo a Nomenclatura Gramatical Brasileira (NGB), aliás é classificado como palavra denotadora de retificação. Em gramáticas e dicionários de autores consagrados, esse item é classificado conforme a NGB e como advérbio. Durante a pesquisa, verificamos a flutuação categorial desse elemento, que também assume características de conjunção, conector reformulativo e operador argumentativo, além da mencionada classificação tradicional. Observamos sua frequência e usos, em textos de modalidade oral, do corpus Discurso & Gramática, sob a luz da Linguística Funcional Centrada no Uso. Os fatores analisados, calcados no aspecto semântico, são os seguintes: posições nos textos, frequência de uso, graus de escolaridade e gêneros textuais. A análise aponta que esse elemento, bastante utilizado no português do Brasil, serve às diversas funções discursivas, tais como: reformulação, retificação integral, retificação parcial, inclusão (de argumentos), dentre outras. Não obstante à classificação imposta pela NGB, os resultados apontam para uma versatilidade desse elemento linguístico, quando analisado nos contextos em que é instanciado.
Considerações acerca do vocábulo "foda" em usos contemporâneos
Authors: Alves Rosangela Jovino , Ferreira Mateus Fornazieri Gonçalves , Antônio Pedro Henrique Silva
Published: July 2020

As palavras consideradas ‘palavrões’ ocupam, ainda hoje, um valor de tabu linguístico, ou seja, são, de alguma forma, proibidas nos usos linguísticos. O enquadramento dessas palavras como tabus deve-se ao fato de que, tradicionalmente, seu valor semântico é pejorativo, indicando ofensas gerais, órgãos sexuais ou o próprio ato sexual. A partir dessa premissa, este trabalho tem por objetivo apresentar os resultados preliminares de um estudo desenvolvido sobre os palavrões na contemporaneidade, mais especificamente as investigações sobre o vocábulo foda, com o intuito de investigar se, apesar de surgir com denominação relacionada à relação sexual, essa palavra ainda mantém sua acepção de tabu ou tem assumido novos valores semânticos e novas funcionalidades linguísticas na atualidade. Para investigação desse elemento, foram selecionados comentários on-line, escritos, feitos em canais do YouTube cuja temática aborda jogos on-line comumente jogados por adolescentes. Para análise do corpus desta pesquisa, são utilizados os preceitos teóricos do Funcionalismo, uma corrente de estudos linguísticos que investiga os elementos linguísticos a partir de seus usos em contextos reais de comunicação, buscando compreendê-los e descrevê-los. Neste trabalho, utilizaremos, especificamente, os preceitos propostos pela perspectiva multissistêmica da língua, proposta por Castilho (2006, 2007, 2010).
Corpus approach towards narrative analysis of tense and aspect
Authors: Barros Camila Antônio
Published: July 2020

A pesquisa aqui apresentada centra-se em como os parâmetros de tempo e aspecto são úteis para a análise da narrativa. Esse estudo pressupõe narrativas como textos com uma elaboração e progressão temporal que demanda as capacidades cognitivas de fore- e backgrounding. Essa perspectiva cognitiva dialoga com a posição laboviana para a análise da narrativa no sentido em que a oposição de Figura e Fundo podem ser marcadas por verbos. Para entender como tempo e aspecto verbais são organizados em narrativas de fala espontânea de português brasileiro, os monólogos do minicorpus C-ORAL-BRASIL I (RASO; MELLO, 2012) foram anotados quanto a suas categorias verbais e categorias labovianas (orientação, complicação e avaliação). Os resultados apontam para uma tendência em marcar majoritariamente a complicação com o pretérito perfeito do indicativo, enquanto a avaliação e orientação serão marcadas pelo presente do indicativo e pelo imperfectivo. O aspecto lexical mostrou uma assimetria entre télicos e não télicos, e uma maior proporção de verbos de accomplishment e achievement em estruturas de complicação.

Diagnosis and management of Kawasaki disease
Authors: Roh Da Eun , Kwon Jung Eun , Kim Yeo Hyang
Published: July 2020

Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a common form of vasculitis in childhood. Among the recent trends in Kawasaki disease, it is notable that the prevalence rate is increasing, and the proportion of “incomplete” Kawasaki disease is also increasing. A delayed diagnosis with prolonged fever can cause complications, such as coronary artery aneurysm and decreased myocardial contractility. These complications might lead to significant morbidity and mortality. Kawasaki disease is diagnosed when the patient meets the principal criteria for clinical symptoms. Following the diagnostic criteria can prevent overdiagnosis but lead to missing of the incomplete form of the disease. Therefore, it is important to accurately understand Kawasaki disease. As the coronavirus disease 2019 (COVID-19) pandemic continues, concerns about a novel severe Kawasaki-like disease in children related to COVID-19 emerges. Indeed, there have been several reports of Kawasaki-like disease related to COVID-19 in children. Kawasaki disease is no longer rare and is often encountered at hospitals. This paper will provide useful and accurate information on Kawasaki disease.
Etiology and treatment of chest pain in children and adolescents
Authors: Yoon Kyung Lim
Published: July 2020

Chest pain is a very common symptom in pediatric patients. Although children with chest pain are relatively unlikely to be suffering from significant cardiac diseases, it is important not to overlook life-threatening diseases. Complete history taking and physical examination––which involves identifying the duration of pain, onset, character, associated symptoms, and aggravating factors––are extremely important. The most common causes of pediatric chest pain are idiopathic and musculoskeletal, while less than 3% of cases are of cardiac origin. Recent studies indicate that chest pain resulted from psychosomatic disorders increases in non-cardiac chest pain in children and adolescents. The reassurance of the benign nature of chest pain is enough in most cases of non-cardiac chest pain in children and adolescents. When echocardiography is performed on patients with exertional chest pain, it is important to confirm the origin of coronary artery to exclude any coronary anomaly. Exertional chest pain, combined syncope, and symptoms of myocardial ischemia should raise the suspicion of significant cardiac diseases. When the chest pain is accompanied by red flag signs, physicians must refer the patients to a pediatric cardiologist.
Evaluation and diagnostic approach for heart murmurs in children
Authors: Choi Hee Joung
Published: July 2020

Heart murmurs are common in children. Most of them are innocent murmurs with normal heart anatomy and function, and only a few are pathologic murmurs with congenital heart anomaly or abnormal heart function. However, a heart murmur may be the sole symptom of serious heart disease. Therefore, careful evaluation of heart murmurs for distinguishing pathologic murmurs from innocent murmurs is important. Heart murmurs are described by their intensity, timing in the cardiac cycle, location, transmission, and quality. Murmurs, such as a holosystolic or diastolic murmur, of grade 3 or higher intensity, harsh quality, an abnormal S2, a systolic click, or increased intensity when the patient stands are more likely to be pathologic murmurs. Innocent murmurs are more likely to be systolic murmurs, with soft sounds, short duration, low pitch, and varying intensity with phases of respiration and posture (disappears with standing). Not only auscultation but also physical examination findings are important to evaluate heart murmurs. The gold standard test for the evaluation of any potentially pathologic murmur is echocardiography. For the appropriate use of echocardiography, close physical examination, including auscultation, is essential and requires considerable practice.

Abstract. Atmospheric effects of solar proton events (SPEs) have been studied for decades, because their drastic impact can be used to test our understanding of upper stratospheric and mesospheric chemistry in the polar cap regions. For example, odd hydrogen and odd nitrogen are produced during SPEs, which leads to depletion of ozone in catalytic reactions, such that the effects are easily observed from satellites during the strongest events.
Until recently, the complexity of the ion chemistry in the lower ionosphere (i.e., in the D region) has restricted global models to simplified parameterizations of chemical impacts induced by energetic particle precipitation (EPP). Because of this restriction, global models have been unable to correctly reproduce some important effects, such as the increase in mesospheric HNO3 or the changes in chlorine species.
Here we use simulations from the WACCM-D model, a variant of the Whole Atmosphere Community Climate Model, to study the statistical response of the atmosphere to the 66 strongest SPEs which occurred in the years 1989–2012. Our model includes a set of D-region ion chemistry, designed for a detailed representation of the atmospheric effects of SPEs and EPP in general. We use superposed epoch analysis to study changes in O3, HOx (OH + HO2), Clx (Cl + ClO), HNO3, NOx (NO + NO2) and H2O. Compared to the standard WACCM which uses an ion chemistry parameterization, WACCM-D produces a larger response in O3 and NOx and a weaker response in HOx and introduces changes in HNO3 and Clx. These differences between WACCM and WACCM-D highlight the importance of including ion chemistry reactions in models used to study EPP.
Investigating the Dust Flux in the Meteoric Smoke Sampler (MESS) Instrument for Sampling Dust in the Mesosphere

Published: July 2020

Abstract. We report and discuss the design of a rocket instrument to collect mesospheric dust particles that are composed of ice and include smaller refractory meteoric smoke particles (MSP). We expect that the ice components melt and that MSP are collected. The instrument consists of a collection device with an opening and closure mechanism and an attached conic funnel. Attaching the funnel increases the sampling area in comparison to the collection area which is kept small since this determines the size of the closure device which is a critical component to be designed for sea recovery. The instrument will collect primary particles that directly hit the collection area and secondary particles that form from mesospheric dust hitting the funnel. We simulate the entry and impact of dust onto the detector considering their trajectories in the airflow and the fragmentation at the funnel. We estimate the collection efficiency of the instrument and the impact energy of particles at the collecting area. The design considered has a sampling area of 5 cm diameter and a collection area of 1.8 cm diameter. To estimate the expected amount of collected dust we assume collection during rocket flight through a 0.5 to 4 km dust layer with dust number densities and dust sizes at 85 km as derived from lidar observations (Kiliani et al., 2015). Assuming the collected particles contain 3 % volume fraction of MSP, we find that the instrument would collect of the order of 1014 to 1015 amu of refractory MSP particles. The estimate basis on the assumption that the ice components are melting and the flow conditions in the instruments are for typical atmospheric pressures at 85 km.
Greenland temperature and precipitation over the last 20 000 years using data assimilation

Abstract. Reconstructions of past temperature and precipitation are fundamental to modeling the Greenland Ice Sheet and assessing its sensitivity to climate. Paleoclimate information is sourced from proxy records and climate-model simulations; however, the former are spatially incomplete while the latter are sensitive to model dynamics and boundary conditions. Efforts to combine these sources of information to reconstruct spatial patterns of Greenland climate over glacial–interglacial cycles have been limited by assumptions of fixed spatial patterns and a restricted use of proxy data. We avoid these limitations by using paleoclimate data assimilation to create independent reconstructions of mean-annual temperature and precipitation for the last 20 000 years. Our method uses oxygen isotope ratios of ice and accumulation rates from long ice-core records and extends this information to all locations across Greenland using spatial relationships derived from a transient climate-model simulation. Standard evaluation metrics for this method show that our results capture climate at locations without ice-core records. Our results differ from previous work in the reconstructed spatial pattern of temperature change during abrupt climate transitions; this indicates a need for additional proxy data and additional transient climate-model simulations. We investigate the relationship between precipitation and temperature, finding that it is frequency dependent and spatially variable, suggesting that thermodynamic scaling methods commonly used in ice-sheet modeling are overly simplistic. Our results demonstrate that paleoclimate data assimilation is a useful tool for reconstructing the spatial and temporal patterns of past climate on timescales relevant to ice sheets.
Global Storm Tide Modeling with ADCIRC v55: Unstructured Mesh Design and Performance

Published: July 2020

Abstract. This paper details and tests numerical improvements to ADCIRC, a widely used finite element method shallow water equation solver, to more accurately and efficiently model global storm tides with seamless local mesh refinement in storm landfall locations. The sensitivity to global unstructured mesh design was investigated using automatically generated triangular meshes with a global minimum element size (MinEle) that ranged from 1.5 km to 6 km. We demonstrate that refining resolution based on topographic seabed gradients and employing a MinEle less than 3 km is important for the global accuracy of the simulated astronomical tide. Our recommended global mesh design (MinEle = 1.5 km) based on these results was locally refined down to two separate MinEle (500 m and 150 m) at the coastal landfall locations of two intense storms (Hurricane Katrina and Super Typhon Haiyan) to demonstrate the model's capability for coastal storm tide simulations and to test the sensitivity to local mesh refinement. Simulated maximum storm tide elevations closely follow the lower envelope of observed high water marks (HWMs) measured near the coast. In general, peak storm tide elevations along the open coast are decreased and the timing of the peak occurs later with local coastal mesh refinement. However, this mesh refinement only has a significant positive impact on HWM errors in straits and inlets narrower than the MinEle, and in bays and lakes separated from the ocean by these passages. Lastly, we demonstrate that the computational performance of the new numerical treatment is one-to-two orders of magnitude faster than studies using previous ADCIRC versions because gravity-wave based stability constraints are removed allowing for larger computational time steps.

The aim of the research is the determination of the total antioxidant activity and the content of phenolic compounds of the leaves of 12 species of non-traditional plants, namely, Amelanchier alnifolia (Nutt.) Nutt. ex M. Roem., Aronia mitschurinii A.K. Skvortsov & Maitul., Castanea sativa Mill., Chaenomeles japonica (Thunb.) Lindl., Cornus mas L., Diospyros kaki L., Diospyros lotus L., Diospyros virginiana L., Lycium barbarum L., Lycium сhinense Mill., Pseudocydonia sinensis (Thouin) C.K. Schneid., Ziziphus jujuba Mill. Total phenolic content was evaluated using the Folin-Ciocalteu reagent assay. Antioxidant activity was measured using two different methods (DPPH – 2,2-diphenyl-1-picrylhydrazyl, MRAP – molybdenum reducing antioxidant power). Significant variability was observed in phenolic compounds content and total antioxidant activity. Total polyphenol content ranged from 38.02 (Z. jujuba) to 80.58 (C. sativa) mg GAE.g-1 DM, total flavonoid content from 22.47 (P. sinensis) to 54.61 (L. barbarum) mg QE.g-1 DM and phenolic acids content from 3.51 (A. mitschurinii) to 24.67 (Ch. japonica) mg CAE.g-1 DM. All tested samples exhibited DPPH• radical scavenging activities with values from 6.92 (A. mitschurinii) to 9.0 (C. mas) mg TEAC.g-1 DM. Antioxidant activity by molybdenum reducing antioxidant power method ranged from 109.43 (A. mitschurinii) to 322.95 (C. mas) mg TEAC.g-1 DM. Differences between the species of non-traditional plants were significant in all observed parameters. Obtained results of phytochemical composition demonstrated the possibility of leaves' use of non-traditional plants as sources of valuable bioactive compounds with health-promoting and disease-preventing properties.
