Efficient Mechanism for Data Gathering and Transmission in Multihop Wireless Sensor Networks
Authors: Jeon Junheon 
Published: September 2020

In this paper, we propose an efficient mechanism for data gathering and transmission in multi-hop wireless sensor networks. In wireless sensor networks, data packets are transferred to the sink node. So many packets are gathered around the sink, resulting in significant delay and collision. To solve this problem, the proposed mechanism used a two-way method; one method works between 1-hop nodes from the sink node and the sink node. In this method, the data packet is transmitted in predefined time to reduce collision and delay. The other method works between nodes except the sink node. In this method, receiver nodes use BRN (backup receiver node) mechanism to reduce energy consumption, thereby increasing the lifetime of the entire networks. In the BRN mechanism, a receiver node that has received a data packet once does not participate in receiving data packets twice in succession by changing its status value. The reason that the receiver node participating in the data packet transmission once does not participate in receiving the second consecutive data packet is to solve the hot spot problem in which two receiver nodes alternately receive the data packet. Also, we propose an enhanced method for data gathering. The proposed method is used for the intensity and direction of the signal in order to increase the reliability of the duplicate data packet. Our simulation and numerical analysis results show that our mechanism outperforms X-MAC in terms of transmission delay and energy consumption.

Published: September 2020

Overtime, science has been developing and trying to use modelling system in the management of hydrology. In this paper, we present a sensitivity analysis for the HEC-HMS rainfall-runoff model. Sensitivity analysis is used to determine the parameter which most influences the result of the model. The main objective of this research is to investigate the sensitivity of parameter in model and to analyze the influence of the graph types used for unit hydrograph. In addition, we also compare the result of lumped and semi-distributed models based on stream order to analyse a common watershed issue. This study will make a model of rainfall-runoff using a sub-catchment distribution method based on stream order. ArcGIS and HEC-HMS were used as softwares to process data. The data needed in this study come from secondary data sourced from various sources. The data that will be processed first is DEM (Digital Elevation Model). DEM used in this study was sourced from the Geospatial Information Agency or commonly referred to as DEMNAS (The National DEM). ArcGIS will process geospatial data in the form of DEM which data results can be used directly to make model in HEC-HMS. Then, the results of the rainfall-runoff model will be calibrated using observed unit hydrograph. From the result of sensitivity analysis, it was concluded that impervious is the most sensitive parameter. Moreover, this paper also can be used as guidelines for use in rainfall-runoff modelling on HEC-HMS.
Metaphors of the prospective teachers regarding the concept of music
Authors: Yuksel Gozde 
Published: September 2020

How teachers perceive concepts and facts is very important because teaching is a profession capable of shaping the cognitive, affective and behavioural behaviours of society through education. This research aims to determine the perceptions of prospective teachers studying at teacher education programmes of different fields regarding the concept of music. The main purpose here is to determine how music, which has an important place in human life with its individual, social, cultural, economic and educational functions, is perceived by prospective teachers. This research was conducted according to the descriptive survey model. The participants of the research consisted of three categories and a total of 186 people: prospective teachers attending departments whose curriculums do not include music lessons (PT, n = 57), prospective teachers attending departments whose curriculums include music lessons (preschool teaching, classroom teaching) (PTM, n = 66) and prospective music teachers (PMT, n = 63). The data were obtained through a form asking the participants to complete the statement â€˜Music is like ... because ...â€™. The analysis of the produced metaphors was carried out in five steps: (1) coding and extracting, (2) collecting sample metaphors, (3) developing categories, (4) ensuring validity and reliability and (5) transferring data to Statistical Package for the Social Sciences for quantitative data analysis. As a result of the research, based on 83 different metaphors produced by prospective teachers, these metaphors were divided into seven categories. When the distribution of perceptual categories by participant type was examined, it was observed that the perceptions of the participants changed according to whether they took music lessons and how often they took them.

Educação emancipatória e atualidade do pensamento ético-político de Paulo Freire
Authors: Polli José Renato 
Published: September 2020

Este trabalho tem como propósito contribuir para a desmistificação das atribuições pejorativas sugeridas por diferentes atores do campo não progressista, sustentadas em desinformação e falta de referenciais sólidos de análise, sobre o sentido emancipatório da obra de Paulo Freire e suas incidências sobre a educação em direitos humanos. Também tem o objetivo de analisar as sugestões teóricas de Freire como caminhos para a construção de mecanismos de consolidação de uma radicalidade democrática no seio da sociedade brasileira. Setores da sociedade sugerem que Paulo Freire seria um autor de vertente marxista, postulador de doutrinas ortodoxas “esquerdistas” nos processos de educação formal, justificando propostas cujo teor têm como objetivo a contraposição a esta suposta doutrinação, como o projeto denominado “Escola sem partido”. Buscamos demonstrar que Paulo Freire tem como preocupação primeira o de caráter ontológico nos processos educativos, a formação humana, indicando meios educacionais para o aprimoramento da reflexão e da ação intimamente relacionadas, que levem ao aprimoramento do ser humano e que, no bojo desta preocupação, existe um objetivo maior, emancipatório, comportando todas as ordens deste aprimoramento: a promoção da justiça, o caráter laico e universal da escola pública, o direito à livre manifestação de ideias, o respeito às realidades culturais de cada estudante, a construção coletiva do conhecimento e a defesa dos direitos humanos.

Published: September 2020

Hard Disk Drive (HDD) as a data storage device when operated with high temperatures (around 66oC), its function will be constrained. The CoFe alloys have a large coercivity field and can be patterned in very small sizes that are suitable for HDD devices. In this study, Co1-x Fex cube alloy was used (x = 0.25; 0.30; 0.50; 0.75). Samples were treated with temperature changes to get the Curie temperature. The coercivity field value is obtained by giving the external field and temperature below Curie temperature and also above Curie temperature to the samples. The VAMPIRE software is a micromagnetic simulation program based on atomistic models. The results showed that Curie’s temperature decreased when Co content increased. The composition of Co0.25 Fe0.75 has the highest Curie temperature that is equal to 1075 K. The temperature Curie is not affected by the size of the cube. When the sample is given a temperature rise below the Curie temperature, the value of the coercivity field decreases. The value of the coercivity field is very difficult to determine when the temperature used is above the Curie temperature. The percentage of composition does not affect the coercivity field value. Therefore, cube-shaped CoFe material is very suitable for use as a material data storage device operated at temperatures below the Curie.

Published: September 2020

Introdução: Estudos para identificação humana baseados na antropologia visam estimar o sexo, a ancestralidade, a idade e a estatura. Dentre as características passíveis de avaliação o sexo é a que apresenta maior relevância. Objetivos: O estudo buscou verificar se o dimorfismo sexual é apontado quando se analisa a massa de mandíbulas edêntulas secas, bem como a viabilidade da construção de um modelo de regressão logística para a estimativa do sexo. Metodologia: No presente estudo observacional transversal, foram analisadas e pesadas 173 mandíbulas edêntulas provenientes de Biobanco, separadamente, com a utilização de balança digital semi-analítica. Para a calibração dos pesquisadores houve a aplicação de análise de correlação intra-classe e intra-examinador segundo Szklo e Nieto (2014). A balança utilizada, da marca Welmy modelo W3, passa por manutenção técnica na própria instituição, garantindo assim, sua precisão de pesagem. Resultados: Na avaliação da massa das mandíbulas edêntulas se mostraram dimórficas, havendo diferenças desta entre masculinas e femininas, sendo significativamente dimórficas. Também foi possível construir dois modelos de regressão logística, sendo um para a estimativa do sexo Logito = 0.454 + 0.633*Idade+ (-0.770*Mandíbula edêntula) e um para a estimativa da ancestralidade (branco e não branco) Logito = -1.776 + 0.392*Mandíbula edêntula. Conclusão: O modelo de regressão logística para estimativa do sexo obtido apresenta acurácia de 71,2%, podendo ser utilizado como método auxiliar na estimativa do sexo. Já o modelo de regressão logística para estimativa da ancestralidade obtido, apresenta acurácia de 62,7%, permitindo o seu uso como método auxiliar na estimativa da ancestralidade em brasileiros.

Published: September 2020

Introdução: A orientação de comportamento fornecida pelo(a) cirurgião(ã) dentista alivia medo e ansiedade, ajuda a construir uma relação de confiança com a criança promovendo atitude positiva. No Brasil, toda criança tem direito, assegurado pelo ECA, a ser educada sem uso de castigo físico ou tratamentos cruéis ou degradantes. Objetivo: Realizar uma revisão da literatura narrativa sobre técnicas de manejo de comportamento em Odontopediatria, trazendo à luz uma abordagem dos aspectos éticos e legais relacionados ao cuidado e proteção da vida do(a) paciente infantil. Metodologia: Foram utilizados estudos relacionados à temática, em livros e artigos publicados em periódicos científicos, em inglês e português, nas bases de dados eletrônicos: PubMed/Medline, Scielo, Lilacs e Google Scholar no período de 2000 até 2019. Resultados: Entre todas as técnicas de controle de comportamento infantil, a mais realizada e aceita pelos(as) odontopediatras e responsáveis é a dizer-mostrar-fazer. As outras técnicas, como reforço positivo, distração, modelagem, controle de voz, podem ser usadas em conjunto para melhor conforto e segurança da criança. É necessário que o(a) cirurgião(ã) dentista aprenda a identificar comportamentos de ansiedade e seja capaz de estabelecer uma adequada relação com o(a) paciente infantil de modo a não causar nenhum dano físico ou moral (com consequências éticas e legais). Considerações finais: O conhecimento técnico e científico do manejo do comportamento infantil no atendimento odontológico é fundamental. Além disso, o(a) odontopediatra deve ficar atento(a) aos aspectos legais e éticos deste manejo, em busca do desenvolvimento físico e emocional infantil de modo satisfatório e não prejudicial.

E A PANDEMIA SEGUE…

Mas será que segue mesmo? Ou você, assim como eu, tem a sensação de “será que só eu ainda percebo que estamos em meio a uma pandemia? ”. Afinal... aqui no Brasil, pico virou platô... Isolamento virou flexibilização... O número de mortes que chocava em terras estrangeiras, virou lugar comum por aqui... Mas, o futebol voltou... Então...
Então, vamos falar de RBOL! Em meio a pandemia de COVID-19, a RBOL – Revista Brasileira de Odontologia Legal também atingiu um pico. Sim! Tivemos um recorde de submissão de novos artigos científicos nos últimos meses. Uma verdadeira “pandemia” de trabalhos em Odontologia Legal (mas essa pandemia é das boas). E, nesse cenário, chegamos a um novo número, uma verdadeira “vacina” para quem tem pouco acesso à informação em Odontologia Legal (e essa vacina é brasileira – nada de produção russa, chinesa ou outras). Desculpem os trocadilhos com o momento, mas o bom humor não precisa ficar distante socialmente, ainda que nesse singelo editorial, não é mesmo?! Ops! De novo o trocadilho!
Coexisting Late Cenozoic Potassic and Sodic Basalts in NE China: Role of Recycled Oceanic Components in Intraplate Magmatism and Mantle Heterogeneity

Published: September 2020

AbstractThis study presents an integrated geochemical study of the Wudalianchi-Erkeshan potassic basalts and Halaha sodic basalts of NE China, and uses these data to further our understanding of the petrogenetic relationships between the coeval potassic and sodic basalts in this region. The potassic basalts with high concentrations of K2O have arc-like trace-element compositions and enriched Sr-Nd-Hf isotopic compositions with unradiogenic 206Pb/204Pb values (16.77–16.90). In contrast, the sodic basalts with high concentrations of Na2O have OIB-like trace-element compositions and depleted Sr-Nd-Hf isotopic compositions with radiogenic 206Pb/204Pb values (18.27–18.40). These data suggest that the potassic and sodic basalts were derived from mixed depleted mid-ocean-ridge basalt mantle (DMM) and enriched mantle source end-members, where the enriched end-members are ancient sediment for the potassic basalts and Pacific oceanic crust for the sodic basalts. The combined geophysical and geochemical data indicate that these two enriched end-members are located in the mantle transition zone. We propose that partial melting of upwelling asthenospheric mantle comprising ambient DMM and recycled materials shifting from the ancient sediment to the Pacific oceanic crust could have produced the coeval potassic and sodic basalts in NE China. The proposed mantle sources for the potassic and sodic basalts indicate that the upper mantle beneath NE China was highly heterogeneous during late Cenozoic.

Consumo sostenible en la Universidad EAN: una cuestión de educación
Authors: Urdaneta Acevedo Juan José 
Published: September 2020

Con el tiempo, el cambio climático y sus efectos en la sociedad se hacen más evidentes; sin embargo, esto no tiene por qué ser un problema que siga aumentando, puesto que la solución está en los consumidores. Dentro de este trabajo, se analiza el comportamiento sobre el consumo sostenible en la Universidad EAN, con la aplicación y el análisis de una encuesta realizada a los estudiantes de pregrado de la universidad; se estudian además los factores que más pueden afectar el consumo sostenible. A partir de la encuesta, se encuentra que los factores que más afectan el consumo sostenible tienden a estar relacionados con los hábitos de consumo impartidos por la educación o por la influencia del ambiente en el que se encuentra el estudiante. Los resultados del estudio demuestran la demanda que existe por un sistema de información o de productos que se diferencien por estas características para cambiar el comportamiento del consumidor.
Acute Versus Chronic Administration of Calcineurin-Inhibitors Differentially Affect T-Cell Function
Authors: Kirchhof Julia , Wilde Benjamin , Schmidt Justine , Mülling Nils , Petrakova Liubov , Brinkhoff Alexandra , Schedlowski Manfred , Witzke Oliver 
Published: September 2020

Background:
Calcineurin-inhibitors (CNI) are used in renal transplant patients (RTX) to
prevent rejection. CNI mainly suppress T-cell mediated immunity but very little is known about
the impact of long-term treatment with CNI on T-cell function.

Objective:
We investigated the immunological effects of long-term CNI intake in RTX patients in
comparison to short-term CNI administration in healthy controls (HC).

Methods:
Blood was drawn from 30 RTX patients with long-term CNI treatment. In addition,
blood was sampled from HC with short-term CNI treatment (four dosages) before the first and 2
hours after the last CsA intake. T-cells were analyzed for cytokine production, proliferation, and
CD25 expression.

Results:
Short-term CNI reduced T-cell derived IL-2 and IFNγ as well as T-cell proliferation in
HC. IFNγ was not suppressed in patients with long-term CNI treatment. IL-2 production, CD25 expression,
and T-cell proliferation were enhanced in long-term CNI patients.

Conclusion:
Suppression of IFNγ/IL-2 and T-cell proliferation is weaker during long-term CNI
treatment in patients compared to short-term treatment in healthy subjects. Enhanced CD25 expression
may lower the threshold for T-cell activation during long-term CNI treatment.

Research on Practice of Sustainable Urban Development–Since the Early Twentieth Century to Contemporary Trends
Authors: Lin Kuanwen 
Published: September 2020

Background:
This study investigated the evolution of planning since the Garden city movement and trends in contemporary eco-city practices. Creating more dialogues between the past and present is essential for clarifying the context of neighborhood planning to that of sustainable urban development and their potential future trends.

Objectives:
This study referenced the evolution of major neighborhood planning movements to address the requirements of urban sustainability since the early twentieth century, namely the garden city, neighborhood unit, modernism, Neo-traditionalism, and Eco-urbanism. We divided these into the categories of “premodernism” and “postmodernism” in our analysis.

Methods:
First, the secondary data research method was used for the literature review. Second, acase study was conducted to analyze the planning of SSTEC. Third, we adopted six codesto investigate SSTEC issues and performed a correlational analysis based on the key criticisms of five neighborhood planning movements.

Results:
The results show that SSTEC as positive or negative aspects of sustainable development and found that all correlations were negative in the premodernist period, whereas planning movements in the postmodernist period represented significant progress.

Conclusion:
(a) the omission of public participation represents the highest potential risk for the planning movement; and (b) lessons can be learned from modernism and through noticing bilateral collaborative trends.
