Published: July 2018

The necessity for processing the huge data has become a critical task in the age of Internet, even though data processing has evolved into a next generation level still data processing and information extraction has many problems to solve. With the increase in data size retrieving useful information with a given span of time is a herculean task. The most optimal solution that has been adopted is usage of distributed computing environment supporting data processing involving suitable model architecture with large complex structure. Although processing has achieved good amount of improvement, efficiency, energy utilization and accuracy has been compromised. The research aims to propose an efficient environment for data processing with optimized energy utilization and increased performance. Hadoop environment common and popular among big data processing platform has been chosen as base for enhancement. Creating a multi node Hadoop cluster architecture on top of which an efficient cluster monitor is setup and an algorithm to manage efficiency of the cluster is formulated. Cluster monitor is incorporated with Zoo keeper, Yarn (Node and resource manager). Zoo keeper does the monitoring of cluster nodes of the distributed system and identifies critical performance problems. Yarn plays a vital role in managing the resources efficiently and controlling the nodes with the help of hybrid scheduler algorithm. Thus this integrated platform helps in monitoring the distributed cluster as well as improving the performance of the overall Big Data processing.

Erroneous message discovery with data acquisition and secret communication in cellular networks
Authors: Balakrishna R , Anandan R , Sajeev Ram A
Published: July 2018

Cellular networks are susceptible to different varieties of security barrages, inclusive of erroneous message inoculation, message falsification and monitoring. Sensitivity knots can be adjudicate by invaders and the adjudicate knots can misinterpret message integrity by inoculating erroneous message. Erroneous message can be inoculated by adjudicate sensitivity knots in different measures, Inclusive of data acquisition and broadcasting. In a System the erroneous message exposure methods contemplate the erroneous message inoculations during the message promoting only. In an (SEP) symmetric en-route purifying schemes facilitates broadcasting knots and central terminal will expose erroneous message with a assertive possibility. In an interlaced step-by-step validation pattern Sensitivity knots are not granted to execute the data acquisition during message promoting. The Capricious Cipher based En-route purifying scheme (CCEP) nips erroneous message en-route without balanced key distribution. Message confidentiality means message to be enciphered at the origin knot and deciphered at the terminal. However, message acquisition methods usually need any enciphered sensitivity message to be deciphered at data acquisition. The essential idea at the rear of the erroneous message exposure algorithm is to make team of sensitivity knots in which one team operates a message authentication code (MAC) of promoting message and the alternate team afterwards checks the message using the MAC. Data acquisition is equipped in cellular sensitivity network in order to remove message repetition, minimize message communication, and increase message efficiency.

Gesture based wireless control for a robotic manipulator
Authors: Vijay Joseph Arockia , Mathur Akshat , Verma Jatin , Singh Ankita
Published: July 2018

This project plays a very important role to complement the industrial and automation field. Nowadays, robots are used in several fields of engineering and manufacturing and the systems for controlling or actuating them have also enhanced from the past. The use of gestures for controlling them has been the new trend to control the movement of robotic manipulators. The various methodologies for controlling them are motion tracking, image processing and by using Kinect sensors. All these methods can be used as a teach pendant where one can provide the movement of the manipulator as a preset and the manipulator can carry out the same motion repetitively, or in the case of motion tracking and while using Kinect sensors, the user is bound to a confined area where the cameras can monitor the user’s body. Here, we propose a wireless controlled robotic arm system for tool handling (pick and place) and many other applications where human reach is elusive. The result is that the gestures of the human hand are in sync with the manipulator’s movement. Further, this robotic arm has been implanted beneath a drone which would then have the ability to reach certain heights where human reach is impervious or might put a human’s life in jeopardy. In this case, the user can maneuver along with manipulator wherever it is used.

Dostrzec i zrozumieć. Porównanie wybranych metod wizualizacji danych ALS wykorzystywanych w archeologii
Authors: Kiarszys Grzegorz , Banaszek Łukasz
Published: July 2018

Application of airborne laser scanning (ALS) for archaeological purposes allows for identification of relief features. Unless the detection is automated, the recognition of archaeological objects in the observed dataset is bounded by the interaction between human mind, eye and visual phenomena that are displayed on the screen. To improve effectiveness of ALS interpretation several visualization techniques have been developed. However, due to their complexity the spatial information produced by these algorithms differs. The aim of the paper is to present the discrepancies between the most popular visualization techniques used for archaeological purposes. Unlike previous attempts, the presented comparison is based on the vector outputs of the interpretative mapping. Therefore, we demonstrate in detail the differences in the morphology as well as quantity of identified archaeological features due to the use of various visualization techniques.

The present article amounts to an attempt to analyze the work Axe is the name of mine by Alexander Dugin — a theorist of Eurasianism ideology in Russia. In this article Dugin touches upon the novel Crime and Punishment by Fyodor Dostoyevsky. Dugin analyzes the novel in the context of cultural opposition between the orthodox Russia and the secular Western Europe, whose symbol is the capital of the Russian Empire— Saint Petersburg. The city in this case is the negation of the orthodox tradition of Moscow — The Third Rome. Dugin extremely relativized the meaning of Dostoyevsky‘snovel.
Aleś Puszkin — czołowa postać białoruskiej awangardy?
Authors: Kuleszewicz Anna
Published: July 2018

Avant-garde, a rebellious band of new trends and tendencies in art that appeared in the early 20th century, lasted for years being transformed, yielding the new forms of expression. It is also a trend of art most often associated with contemporaryBelarusian art (partially due to “school of Vitebsk”, Marc Chagall and Kazimir Malevich), still enjoying popularity in the country. One of the most recognizable Belarusian artistsis Ales Pushkin, born in 1965 in Bobr, associated with the Achremczuk’s National Schoolof Music and the Arts in Minsk and Vitebsk artistic environment. Pushkin is known for his indomitable, rebellious attitude towards the state regime. For many observers, art amateurs and even art critics, the character of his work immediately resembles avant-garde. However, as some researchers noted, Pushkins’ art enters a new dimension,paving the way towards new horizons of contemporary (avant-garde?) art of Belarus.

Published: July 2018

The Groningen natural gas field in the Netherlands – one of Europe’s major gas fields – deploys a “production cluster” infrastructure with extraction, some processing and storage in a single facility. This region is also the site of intensive agriculture and cattle operations. We present results from a multi-scale measurement campaign of methane emissions, including ground and airborne-based estimates. Results are compared with inventory at both the facility and regional level.

Investigation of production cluster emissions in the Groningen gas field shows that production volume alone is not a good indicator of whether, and how much, a site is emitting methane. Sites that are nominally shut down may still be emitting, and vice-versa. As a result, the inventory emission factors applied to these sites (i.e. weighted by production) do a poor job of reproducing individual site emissions. Additional facility-level case studies are presented, including a plume at 150 ± 50 kg CH4 hr–1 with an unidentified off-shore emission source, a natural gas storage facility and landfills.

Methane emissions in a study region covering 6000 km2 and including the majority of the Groningen field are dominated by biogenic sources (e.g. agriculture, wetlands, cattle). Total methane emissions (8 ± 2 Mg hr–1) are lower than inventory predictions (14 Mg hr–1) but the proportion of fossil fuel sources is higher than indicated by the inventory. Apportionment of methane emissions between thermogenic and biogenic source types used ethane/methane ratios in aircraft flasks and ground-based source characterization. We find that emissions from the oil and gas sector account for 20% of regional methane, with 95% confidence limits of (0%, 51%). The experimental uncertainties bound the inventory apportionment of 1.9%, though the central estimate of 20% exceeds this result by nearly 10 times. This study’s uncertainties demonstrate the need for additional research focusing on emissions apportionment, inventory refinement and offshore platforms.
A política e a cultura do “contentamento” no processo da globalização
Authors: Tauchen Jair Inácio
Published: July 2018

O artigo procura apresentar uma crítica referente a política e a cultura do "contentamento", expressão cunhada por John Kenneth Galbraith. A cultura do contentamento está ancorada no laissez faire, ou seja, no compromisso da desregulamentação do mercado. Conforme essa doutrina, a intervenção do governo e, sobretudo, a regulamentação governamental, é vista como desnecessária alem de prejudicial ao processo da globalização. No entanto, o caráter do compromisso é altamente seletivo. Aos olhos da cultura do contentamento, sempre que houver o sumiço do dinheiro, quando a crise se instalar no mercado, e, somente nesses casos, a responsabilidade para encontrar a solução recai sobre o estado.
Uma Abordagem Bayesiana ao Paradoxo do Prefácio
Authors: Cibils Samuel
Published: July 2018

A lógica é uma ciência normativa para os raciocínios? Os seus princípios desempenham algum papel sobre a racionalidade das nossas crenças? Ser logicamente consistente supostamente é um princípio para o raciocínio teórico. Além disso, parece que consistência lógica impõe uma restrição sobre crença racional. No entanto, o paradoxo do prefácio coloca à prova este princípio, uma vez que o 'estado de prefácio' seria um estado racional. Apresentaremos a análise segundo um modelo Bayesiano de graus de crença para exemplificar uma (dis)solução do paradoxo e, simultaneamente, a manutenção do princípio de consistência.

Produção literária e contexto histórico no século XIX: O Mulato, de Aluísio Azevedo
Authors: Magalhães Magna Lima , Moreira Paulo Roberto Staud , Stelter Rafael Eduardo
Published: July 2018

Tomando o romance O Mulato, de Aluísio de Azevedo, como pretexto, o artigo pretende analisar as representações político-literárias que ele comporta, sobre a presença negra no Brasil, no final do oitocentos. A obra transita por entre as estruturas sociais que projetavam múltiplos discursos indicando as relações de poder inferiorizantes do negro, como clérigos, comerciantes e Estado. As representações de manutenção do modo de produção escravo em face do desenvolvimento econômico e construção identitária nacional, convergem na lógica de que a emancipação negra não apenas é uma ameaça ao status quo da elite como perpassa o atraso brasileiro apreendido pelo viés da degeneração racial advindo da mestiçagem. Publicado em 1881, período de grandes mudanças estruturais (processo abolicionista, campanha e proclamação republicana, crescimento da imigração europeia), o livro coincide com a recepção no Brasil de várias perspectivas analíticas, que estimularam e condicionaram o pensar das elites nacionais sobre a participação negra, vista principalmente como entrave a consolidação de uma nação civilizada.

Annual Screening for Chronic Kidney Disease using Urinary Dipstick to Detect Proteinuria among Elderly Patients with Hypertension and Diabetes Mellitus Attending Agbeke Mercy Medical Clinic, Oluyole Cheshire Home, Ibadan, Nigeria
Authors: Ibisola Babalola Adeniyi , Sherratt Margaret
Published: July 2018

Background: Chronic kidney disease (CKD) is a highly prevalent medical condition throughout the world, with worsening indices in the developing countries. The economic burden with renal replacement therapy is something that most developing nations may find difficult to cope with. It is important for those at risk of CKD to be screened and identified early in order to prevent or slow progression to advanced stages. There are different screening methods for CKD, the acceptable minimum is an annual screening with the use of dipstick to detect urinary protein.

Methodology: For the first cycle of the audit, medical records of the elderly hypertensive and diabetic patients attending Agbeke Mercy Medical Clinic were obtained for a retrospective assessment of their annual urinalysis uptake. A ninety percent standard was set for the second audit cycle. This was followed by a three months prospective dipstick (Medi-Test Combi 10® SGL) urinalysis screening, after health talks and a significant subsidization of the screening cost for all the participants were put in place.

Results: The records showed that 37% (32) of the eligible 87 patients had a dipstick urinalysis screening done in the preceding one year. In the three months, 93% (79) were screened for urinary protein with dipstick. 12.6% results were positive for at least 1+ of proteinuria.

Conclusion: Clinical audit is very important in improving clinical practice. It helps to identify areas of practice that may need improvement, as in this case annual screening for CKD with dipstick urinalysis, especially among patients who are at the risk of developing CKD. Despite financial constraints, efforts should be made to make CKD screening a routine in all at-risk patients

Authors: Kaposvári István , Körmöczi Kinga , Horváth Ferenc , Buglyó Alida , Turai Adrienn Réka , Joób-Fancsaly Árpád
Published: July 2018

Abstract:

Introduction and aim: Delayed-onset infection was defined as an infectious swelling and trismus accompained by pain or the presence of suppuration starting after the discharge of the patient, generally a week after surgery. Our aim was to describe incidence and possible risk factors of delayed-onset infection after lower wisdoom tooth removal. Material and methods: Retrospective study of 851 lower third molar surgeries, performed between January 2013 and August 2017 at Semmelweis University Faculty of Dentistry, Department of Oro-Maxillofacial Surgery and Stomatology, has been done. The teeth were removed by 2 surgeons. Under age of 26, a case-control study comprising a total of 150 lower third molar surgeries were done to indentify possible risk factors. Results: 10 delayed-onset wound infections were recorded after suture removal (1.17% of the patients). The mean time elapsing from surgery to delayed-onset infection was 30 days. Lower third molars with total soft tissue coverage, a bigger amount of bone coverage, a lack of distal space (Pell–Gregory class III), deeper impaction (Pell–Gregory classes B, C) or mesioangular tilt are associated with the development of this complication (p<0.05). Female sex and young age seem to be risk factors, too. Conclusion: Patients with risk factors should be warned that infection may still occur several weeks after surgery. The clinicians should observe these patients longer and emphasize keeping their wound clean for a prolonged period. Orv Hetil. 2018; 159(31): 1278–1283.

Hoy en día, el porcentaje de la información disponible en Inglés en Word Wide Web está disminuyendo, debido a que otros lenguajes como: chino, español, árabe y portugués están ganando aceptación y difusión. Este fenómeno ha provocado que el multilingüismo se convierta en uno de los principales retos para el procesamiento inteligente, gestión y recuperación de documentos. Con el fin de hacer frente a este problema de forma eficaz, los sistemas computacionales necesitan el diseño de nuevos modelos o mejorar los modelos tradicionales de representación de documentos. La disponibilidad de repositorios multilingües de conceptos y redes semánticas, ha abierto un enfoque atractivo para modelar documentos escritos en diferentes lenguas, como los vectores de conceptos en un espacio común de representación. En este trabajo se presenta una nueva representación basada en conceptos usando Multilingual Central Repository. Nuestra propuesta  aplica una desambiguación del sentido de la palabra de grano grueso para la selección del concepto apropiado de acuerdo con el tema y los dominios relevantes reflejados en los documentos. Evaluamos experimentalmente nuestro método en la tarea de clasificación de documentos multilingües. Los resultados obtenidos en los experimentos son alentadores y demuestran la utilidad del método propuesto.
A FORMAÇÃO DOCENTE E O PIBID-SUBPROJETO DE BIOLOGIA DO IFRN/MACAU: UMA INTERLOCUÇÃO ENTRE A FORMAÇÃO INICIAL E CONTINUADA
Authors: Lima Gislaine Rocha de , Ferreira Maria Aparecida dos Santos
Published: July 2018

Este estudo tem como objetivo analisar o Programa Institucional de Bolsa de Iniciação à Docência (PIBID), subprojeto de biologia desenvolvido no curso de licenciatura plena em Biologia do IFRN-Campus Macau/RN, e as suas contribuições com a interlocução entre a formação inicial dos licenciandos e a formação continuada dos professores supervisores do programa. A pesquisa consistiu-se em uma abordagem qualitativa, cujo instrumento de coleta de dados configurou-se em uma entrevista semiestruturada. Nas entrevistas, os participantes do subprojeto biologia (licenciandos e professores supervisores) foram indagados a partir de suas experiências no PIBID, cujos questionamentos foram organizados em duas categorias de análise: formação inicial e formação continuada. Ao analisar as perspectivas dos licenciandos sobre a interlocução entre formação inicial e continuada a partir do PIBID percebeu-se que estes visualizam o espaço escolar como um ambiente colaborativo, em que os professores supervisores contribuem para a formação dos licenciandos, ao mesmo tempo em que ao orientar os iniciantes a docência estes professores adquirem novas experiências que serão significativas para seu processo formativo contínuo. Diante das conquistas percebidas e das perspectivas vislumbradas, acredita-se que a atuação do PIBID tem sido positiva na comunidade escolar, contribuindo para o processo formativo de todos os envolvidos, desde os bolsistas de iniciação à docência, até os professores supervisores, mesmo estes não percebendo que ao mesmo tempo em que “eles formam, também se formam”.
ANÁLISE DE VELOCIDADES DE DADOS SÍSMICOS MULTICOMPONENTE DA BACIA DE SANTOS UTILIZANDO TECNOLOGIA OBN E TÉCNICA SWD
Authors: Zuniga Nelson Ricardo Coelho Flores
Published: July 2018

A sísmica multicomponente apresenta um campo de onda bem mais completo do que a sísmica convencional, em decorrência disso ela vem sendo cada vez mais utilizada nos levantamentos sísmicos. Junto dela, a tecnologia OBN (Ocean Bottom Nodes) é necessária em aquisições marítimas para a obtenção de ondas convertidas. Com o aumento da profundidade dos reservatórios encontrados, existe cada vez mais dificuldade com relação à qualidade dos dados de amplitude obtidos, dessa forma aquisições sísmicas durante a perfuração diminuiriam este problema. Entretanto esse conjunto de técnicas e tecnologias torna o evento sísmico de reflexão muito mais complexo, o que dificulta significativamente a análise de velocidades. Com isso, é necessário utilizar métodos de otimização e análise de velocidades que sejam capazes de controlar as características não-hiperbólicas de um evento de reflexão. Para isso, será utilizada uma equação não-hiperbólica multiparametrica buscando efetuar a análise de velocidades por meio do ajuste entre a curva de tempos de trânsito calculada e observada, tratando como um problema de inversão segundo um critério de otimização. Sendo assim, é possível definir se a sísmica multicomponente traz resultados eficientes quando usada durante a perfuração.
A RELAÇÃO DOS ALUNOS DO CURSO DE PEDAGOGIA COM O CONHECIMENTO MATEMÁTICO E SEU ENSINO: UM ESTUDO LONGITUDINAL
Authors: Ortega Eliane Maria Vani , Santos Vinício de Macedo
Published: July 2018

O presente estudo está inserido no campo da Educação Matemática e de forma mais direta relaciona-se à formação dos professores que ensinam Matemática nos anos iniciais do Ensino Fundamental. Trata-se de levantamento descritivo-analítico, no contexto de uma abordagem qualitativa por meio de estudo longitudinal. O estudo foi realizado com estudantes do curso de Pedagogia que ingressaram no curso em 2007 e o concluíram no ano de 2010. Apresentamos resultados sobre a relação dos alunos com o conhecimento matemático e seu ensino durante o período de formação inicial. A partir de textos produzidos pelos sujeitos da pesquisa ao final de cada ano do curso de Pedagogia (2007, 2008, 2009 e 2010), visualizamos alterações em relação ao conhecimento matemático e seu ensino.  Tais alterações indicam que eles terminam o curso mais próximos do conhecimento matemático, afirmam a necessidade de constante estudo sobre essa área e  há rupturas de crenças como aquelas relacionadas à matemática ser inacessível. Também percebemos preocupação dos sujeitos com a relação professor-aluno no processo de ensino e aprendizagem da Matemática bem como com a utilização de atividades diversificadas, brincadeiras, jogos, necessidade de explicar os conceitos de diferentes formas, utilização de diferentes materiais didáticos, necessidade de mostrar aplicações dos conceitos matemáticos.
FILOSOFIA COM CRIANÇAS NA ESCOLA: PRÁTICAS DE LEITURA, ESCRITA E EXERCÍCIO DO PENSAMENTO NA PROBLEMATIZAÇÃO DO TEMPO
Authors: Lermen Sabrina , Schuler Betina
Published: July 2018

Este artigo investiga o exercício do pensamento, pautado pela prática da filosofia com crianças (diferenciando-se da filosofia para crianças), através de práticas de leitura e escrita em uma escola pública na região do Vale do Caí, RS. A partir da perspectiva do pensamento da diferença, operando com autores como Foucault, Deleuze e Kohan, interroga-se de que modos essa experimentação poderia produzir pequenos deslocamentos quanto aos clichês e pensamentos dogmáticos que atravessam nossas vidas. Essa investigação entende o pensamento como essa provocação do fora, viabilizado por diferentes intercessores que irão problematizar o que está naturalizado. Do mesmo modo, opera com a filosofia para além de uma disciplina acadêmica, como uma forma específica de se relacionar com o saber e com a vida. Entende, ainda, a escrita como uma técnica que pode operar transformações sobre nossa experiência. A partir disso, realizou-se a análise de escritas de alunos de 5º ano, cujas regularidades destacadas foram: o discurso salvacionista, valoração da escola como lugar de pensamento, a boa escrita operada como comunicação e a expressão de grande preocupação com a passagem do tempo. A partir dessas regularidades, produziu-se uma oficina filosófica com esses alunos, em que foram inventadas outras possibilidades de leitura e escrita, focando na problematização de nossas relações com o tempo. As escritas produzidas nessa oficina foram igualmente examinadas, destacando-se, pois, uma divisão temporal (e moral) da vida, mas também apresentando deslocamentos importantes quanto ao tempo cronológico, operando com uma diminuição da força pastoral e da infância idealizada, apostando em uma relação mais intensiva com o mesmo.
AMBIENTE INSTITUCIONAL E RESPONSABILIDADE SOCIAL CORPORATIVA NA CAFEICULTURA AFRICANA
Authors: Silva Eduardo Cesar , Azevedo Angélica da Silva , Castro Junior Luiz Gonzaga
Published: July 2018

A cafeicultura é uma atividade econômica importante para os agricultores de muitos países da América, África, Ásia e Oceania. Entretanto, a cafeicultura africana perdeu participação no mercado mundial nas últimas décadas. Este trabalho analisou o declínio da cafeicultura africana sob a perspectiva da Nova Economia Institucional (NEI). O trabalho foi feito em duas etapas. Na primeira, foi realizada uma pesquisa bibliográfica sobre a história política de quatro países que eram os mais importantes produtores de café da África na década de 1960, a saber: Angola, Etiópia, Costa do Marfim e Uganda. Na segunda etapa, foi realizada uma pesquisa documental sobre ações de Responsabilidade Social Corporativa (RSC) de companhias multinacionais de café nos países africanos em anos recentes. Os dados obtidos foram interpretados a partir dos pressupostos da NEI. Os resultados indicam que houve grande instabilidade política nos quatros países analisados, algo que impede o desenvolvimento de instituições capazes de fomentar o desenvolvimento econômico. Nesse contexto, os resultados mostram que a ação das empresas multinacionais preenche um vazio deixado pelo Estado.
PREDICTION OF WATER-BASED PAINT PROPERTIES BASED ON THEIR MINERAL FILLERS: SIMPLEX-PLSR COUPLING APPLICATION
Authors: Nunes da Conceição Paulo Ricardo , Petter Carlos Otávio , Hoffmann Sampaio Carlos
Published: July 2018

The present study shows the optimization of mineral filler blends for use in water-based paints. The aim of the modelling is to evaluate the possibility of creating a model of prediction of the contrast ratio and brightness of the dry film, where the fillers that participate in the system are fillers used commercially by the paint industry. The differential of the use of the mixtures design, called Simplex, is that the predictions are made by carrying out a linear combination between the proportions of the mineral fillers and the response variables. The proposed procedure consists in generating a numerical model that can predict final paint properties depending on the concentrations of the mineral fillers (PCC, GCC and kaolin) used. As support for simplex mixture design, the methods of Partial Least Squares regression and Response Surface were used in the calculations of the models and in the visualization of the response variables.
Ensino Médio na Rede Federal e nas Redes Estaduais: por que os estudantes alcançam resultados diferentes nas avaliações de larga escala?
Authors: Ramos Marise Nogueira
Published: July 2018

O artigo analisa a política de avaliação em larga escala da educação básica no Brasil, problematizando a diferença de desempenho de estudantes das redes públicas e privadas, e no interior da primeira, com destaque para a rede federal de educação profissional e tecnológica.  O curso da análise segue três eixos. O primeiro situa as políticas de avaliação educacional em larga escala face às influências da globalização na educação em nosso país, reconhecendo que, mesmo não perdendo por completo sua autonomia, os estados nacionais de capitalismo dependente se alinham às tendências internacionais. O segundo eixo discute tais avaliações no Ensino Médio, apresentando dados sobre quem são os participantes do Enem, com o intuito de verificar possíveis determinações socioeconômicas dos respectivos desempenhos. Finalmente, demonstra alguns parâmetros de qualidade do ensino que podem explicar as diferenças de desempenhos, confrontando-os com metas e estratégias do Plano Nacional de Educação que visam a melhoria dessa qualidade. Verifica-se o quanto a política educacional está subordinada às avaliações de larga escala e conclui-se sobre a possível inviabilidade de mudanças significativas desse quadro face ao novo regime fiscal instituído pela Emenda Constitucional n. 95/2016.
