Beneficial Effects of Vanadium Additions on the Corrosion of Ti6AlxV Alloys in Chloride Solutions
Authors: Sherif El-Sayed M. , Abdo Hany S. , Alharthi Nabeel H.
Published: February 2020

The beneficial effects of V addition on the corrosion of a newly manufactured Ti6AlxV (x = 2 wt %, 4 wt %, 6 wt %, and 8 wt %) alloys after various exposure periods in 3.5% NaCl solutions were reported. The Ti6AlxV were produced from their raw powders using mechanical alloying. Several electrochemical techniques such as electrochemical impedance spectroscopy, cyclic potentiodynamic polarization, and potentiodynamic current versus time at 300 mV experiments were conducted. The surface morphology and the elemental analysis were performed using scanning electron microscopy and energy dispersive X-ray analyses. All results were consistent with each other revealing that the increase of V content increases the resistance of the alloys against corrosion. The increase of corrosion resistance was achieved by the role of V in decreasing the rate of corrosion as a result of the formation of oxide films on the surface of the alloys. This effect was found to increase with prolonging the immersion time of the Ti6AlxV alloys in the test medium from 1 h to 24 h and further to 48 h.

Published: February 2020

The in situ reaction method for preparing metal matrix composites has the advantages of a simple process, good combination of the reinforcing phase and matrix, etc. Based on the mechanism of forming TiCx particles via the dissolution reaction of solid carbon (C) particles in Cu-Ti melt, the kinetic models for C particle dissolution reaction were established. The kinetic models of the dissolution reaction of spherical, cylindrical, and flat C source particles in Cu-Ti melt were deduced, and the expressions of the time for the complete reaction of C source particles of different sizes were obtained. The mathematical relationship between the degree of reaction of C source and the reaction time was deduced by introducing the shape factor. By immersing a cylindrical C rod in a Cu-Ti melt and placing it in a super-gravity field for the dissolution reaction, it was found that the super-gravity field could cause the precipitated TiCx particles to aggregate toward the upper part of the sample under the action of buoyancy. Therefore, the consuming rate of the C rod was significantly accelerated. Based on the flat C source reaction kinetic model, the relationship between the floating speed of TiCx particles in the Cu-Ti melt and the centrifugal velocity (or the coefficient of super-gravity G) was derived. It was proven that, when the centrifugal velocity exceeded a critical value, the super-gravity field could completely avoid the accumulation behavior of TiCx particles on the surface of the C source, thereby speeding up the formation reaction of TiCx. The goal of this study is to better understand and evaluate the generating process of TiCx particles, thus finding possible methods to increase the reaction efficiency

Published: February 2020

The development of polymer-based devices has attracted much attention due to their miniaturization, flexibility, lightweight and sustainable power sources with high efficiency in the field of wearable/portable electronics, and energy system. In this work, we proposed a polyvinylidene fluoride (PVDF)-based composite matrix for both energy harvesting and energy storage applications. The physicochemical characterizations, such as X-ray diffraction, laser Raman, and field-emission scanning electron microscopy (FE-SEM) analyses, were performed for the electrospun PVDF/sodium niobate and PVDF/reduced graphene oxide composite film. The electrospun PVDF/sodium niobate nanofibrous mat has been utilized for the energy harvester which shows an open circuit voltage of 40 V (peak to peak) at an applied compressive force of 40 N. The PVDF/reduced graphene oxide composite film acts as the electrode for the symmetric supercapacitor (SSC) device fabrication and investigated for their supercapacitive properties. Finally, the self-charging system has been assembled using PVDF/sodium niobate (energy harvester), and PVDF/reduced graphene oxide SSC (energy storage) and the self-charging capability is investigated. The proposed self-charging system can create a pathway for the all-polymer based composite high-performance self-charging system.

Published: February 2020

As complementary metal-oxide-semiconductor (CMOS) transistors approach the nanometer scale, it has become mandatory to incorporate suitable quantum formalism into electron transport simulators. In this work, we present the quantum enhancement of a 2D Multi-Subband Ensemble Monte Carlo (MS-EMC) simulator, which includes a novel module for the direct Source-to-Drain tunneling (S/D tunneling), and its verification in the simulation of Double-Gate Silicon-On-Insulator (DGSOI) transistors and FinFETs. Compared to ballistic Non-Equilibrium Green’s Function (NEGF) simulations, our results show accurate I D vs. V G S and subthreshold characteristics for both devices. Besides, we investigate the impact of the effective masses extracted Density Functional Theory (DFT) simulations, showing that they are the key of not only the general thermionic emission behavior of simulated devices, but also the electron probability of experiencing tunneling phenomena.
A Front-Side Microfabricated Thermoresistive Gas Flow Sensor for High-Performance, Low-Cost and High-Yield Volume Production
Authors: Xue Dan , Wang Jiachou , Li Xinxin
Published: February 2020

In this paper, we present a novel thermoresistive gas flow sensor with a high-yield and low-cost volume production by using front-side microfabricated technology. To best improve the thermal resistance, a micro-air-trench between the heater and the thermistors was opened to minimize the heat loss from the heater to the silicon substrate. Two types of gas flow sensors were designed with the optimal thermal-insulation configuration and fabricated by a single-wafer-based single-side process in (111) wafers, where the type A sensor has two thermistors while the type B sensor has four. Chip dimensions of both sensors are as small as 0.7 mm × 0.7 mm and the sensors achieve a short response time of 1.5 ms. Furthermore, without using any amplification, the normalized sensitivity of type A and type B sensors is 1.9 mV/(SLM)/mW and 3.9 mV/(SLM)/mW for nitrogen gas flow and the minimum detectable flow rate is estimated at about 0.53 and 0.26 standard cubic centimeter per minute (sccm), respectively.

Published: February 2020

P. aeruginosa is the most common Gram-negative organism causing bacterial keratitis. Pseudomonas utilizes various virulence mechanisms to adhere and colonize in the host tissue. In the present study, we examined virulence factors associated with thirty-four clinical P. aeruginosa isolates collected from keratitis patients seeking care at L V Prasad Eye Institute, Hyderabad. The virulence-associated genes in all the isolates were genotyped and characteristics such as antibiotic susceptibility, biofilm formation, swarming motility, pyoverdine production and cell cytotoxicity were analyzed. All the isolates showed the presence of genes related to biofilm formation, alkaline proteases and elastases; however, there was a difference in the presence of genes related to the type III secretion system (T3SS). A higher prevalence of exoU+ genotype was noted in the drug-resistant isolates. All the isolates were capable of forming biofilms and more than 70% of the isolates showed good swarming motility. Pyoverdine production was not associated with the T3SS genotype. In the cytotoxicity assay, the presence of exoS, exoU or both resulted in higher cytotoxicity compared to the absence of both the genes. Overall, our results suggest that the T3SS profile is a good indicator of P. aeruginosa virulence characteristics and the isolates lacking the effector genes may have evolved alternate mechanisms of colonization in the host.

Published: February 2020

Food-producing animals may be a reservoir of vancomycin-resistant enterococci (VRE), potentially posing a threat to animal and public health. The aims of this study were to estimate the faecal carriage of VRE among healthy cattle (n = 362), pigs (n = 350), sheep (n = 218), and poultry (n = 102 flocks) in Switzerland, and to characterise phenotypic and genotypic traits of the isolates. VRE were isolated from caecum content of six bovine, and 12 porcine samples respectively, and from pooled faecal matter collected from 16 poultry flock samples. All isolates harboured vanA. Two different types of Tn1546-like elements carrying the vanA operon were identified. Conjugal transfer of vanA to human Enterococcus faecalis strain JH2-2 was observed for porcine isolates only. Resistance to tetracycline and erythromycin was frequent among the isolates. Our data show that VRE harbouring vanA are present in healthy food-producing animals. The vanA gene from porcine isolates was transferable to other enterococci and these isolates might play a role in the dissemination of VRE in the food production chain.
Intimate Attachment of Escherichia coli O157:H7 to Urinary Bladder Epithelium in the Gnotobiotic Piglet Model

Published: February 2020

Enterohemorrhagic Escherichia coli (EHEC), a pathogenic subset of Shiga toxin-producing E. coli (STEC), is an important cause of hemorrhagic colitis and hemolytic–uremic syndrome (HUS), and a rare cause of urinary tract infections (UTIs) with associated HUS. EHEC strains attach intimately to intestinal epithelium with formation of actin pedestals (attaching-effacing (A/E) lesions); however, the mechanism of EHEC attachment to the uroepithelium is unknown. We conducted a retrospective study on archived urinary bladder specimens from gnotobiotic piglets that naturally developed cystitis associated with EHEC O157:H7 infection following oral inoculation and fecal shedding. Paraffin-embedded bladder tissues from three piglets with cystitis and immunohistochemical evidence of EHEC O157:H7 adherence to the uroepithelium were processed for and examined by transmission electron microscopy. EHEC O157:H7 bacteria were found in one of three piglets, intimately attached to pedestals on the apical surfaces of the superficial urothelium (umbrella cells). Cystitis was significantly associated with the length of survival of the piglets post-inoculation (p = 0.0339; estimated odds ratio = 2.6652). This is the first report of E. coli causing A/E-like lesions in the uroepithelium, and also evidence of the utility of the gnotobiotic piglet as a model for studies of the pathogenesis of EHEC UTIs.
Functional and Structural Roles of the Major Facilitator Superfamily Bacterial Multidrug Efflux Pumps

Published: February 2020

Pathogenic microorganisms that are multidrug-resistant can pose severe clinical and public health concerns. In particular, bacterial multidrug efflux transporters of the major facilitator superfamily constitute a notable group of drug resistance mechanisms primarily because multidrug-resistant pathogens can become refractory to antimicrobial agents, thus resulting in potentially untreatable bacterial infections. The major facilitator superfamily is composed of thousands of solute transporters that are related in terms of their phylogenetic relationships, primary amino acid sequences, two- and three-dimensional structures, modes of energization (passive and secondary active), and in their mechanisms of solute and ion translocation across the membrane. The major facilitator superfamily is also composed of numerous families and sub-families of homologous transporters that are conserved across all living taxa, from bacteria to humans. Members of this superfamily share several classes of highly conserved amino acid sequence motifs that play essential mechanistic roles during transport. The structural and functional importance of multidrug efflux pumps that belong to the major facilitator family and that are harbored by Gram-negative and -positive bacterial pathogens are considered here.

Published: February 2020

As a novel and safe sanitizer, polyhexamethylene guanidine hydrochloride (PHMG) has been used to inhibit the spoilage of agricultural products caused by fungi. However, little is known about its antibacterial effects on vegetables. In this study, we evaluated the disinfection efficacy of PHMG on ready-to-eat lettuce. PHMG (150–200 mg/L) treatment for 5 min was optimal for lettuce disinfection. Compared to several household sanitizers (vinegar: 1% acetic acid; kettle descaler: 1% citric acid; “84” disinfectant: 200 mg/L sodium hypochlorite), PHMG showed the greatest reductions in Escherichia coli O157:H7, Listeria monocytogenes, aerobic mesophilic counts, aerobic psychrotrophic counts and molds and yeasts. Quality analysis of color (as determined by L*, a* and b*) and determination of electrolyte leakage indicated that PHMG did not cause any additional quality loss as compared to other household sanitizers. These results provide a reference for the application of PHMG as a vegetable sanitizer at the ready-to-eat stage.
Arginine Catabolic Mobile Element in Evolution and Pathogenicity of the Community-Associated Methicillin-Resistant Staphylococcus aureus Strain USA300

Published: February 2020

USA300 is a predominant community-associated methicillin-resistant Staphylococcus aureus strain which carries an arginine catabolic mobile element (ACME). ACME contains potential virulence factors including an arginine deiminase (arc) pathway and an oligopeptide permease (opp-3) system, which are proposed to play a role in bacterial virulence and transmission. However, the role of ACME in evolution and pathogenicity of USA300 remains to be elucidated. ACME and arcA deletion mutants were created by allelic replacement from a USA300 clinical isolate. By comparing wild type and isogenic ACME deletion USA300 strains, ACME was shown not to contribute to bacterial survival on plastic surfaces, and mouse skin surfaces. ACME did not contribute to bacterial virulence in cell invasion and cytotoxicity assays, invertebrate killing assays and a mouse skin infection model. Wild-type ACME negative USA300 clinical isolates showed similar associations with invasive anatomic sites as ACME positive isolates. Our experiments also demonstrated that ACME can spontaneously excise from the bacterial chromosome to generate an ACME deletion strain at a low frequency. Our results do not support that the ACME element alone is a significant factor in the transmission and virulence of USA300 strain, and ACME may have been coincidently incorporated into the genome of USA300.

Published: February 2020

Despite the availability of a safe and effective vaccine, in 2018, around 350,000 measles cases were reported worldwide, which resulted in an estimate of 142,300 deaths from measles. Additionally, in 2017, global measles cases spiked, causing the death of 110,000 people, mostly children under the age of 5 years and immunocompromised adults. The increase in measles incidence is caused by the ongoing reduction of vaccination coverage. This event has triggered public and scientific interest. For this reason, we reviewed the pathophysiology of measles infection, focusing on mechanisms by which the virus spreads systemically through the host organism. By reaching the lymphocytes from the airways through a “trojan horse” strategy, measles induces an immunosuppression status. H and F glycoproteins, both expressed in the envelope, ensure attachment of the virus to host cells and spreading from one cell to another by binding to several receptors, as described in detail. The severity of the disease depends both on the age and underlying conditions of patients as well as the social and health context in which epidemics spread, and is often burdened by sequelae and complications that may occur several years after infection. Particular attention was paid to special groups that are more susceptible to severe or atypical measles. An overview of microbiology, symptoms, diagnosis, prevention, and treatment completes and enriches the review.

Published: February 2020

The newly exploited Qiaomaishan Cu−W deposit, located in the Xuancheng ore district in the MLYRB, is a middle-sized Cu–W skarn-type polymetallic deposit. As Cu–W mineralization is a rare and uncommon type in the Middle-Lower Yangtze River Belt (MLYRB), few studies have been carried out, and the geochemical characteristics and petrogenesis of Qiaomaishan intrusive rocks related to Cu–W mineralization are not well documented. We studied two types of ore-bearing intrusive rocks in the Qiaomaishan region, i.e., pure granodiorite porphyry and granodiorite porphyry with mafic microgranular enclaves (MMEs). Age characterization using zircon LA–ICP–MS showed that they were formed almost simultaneously, around 134.9 to 135.1 Ma. Granodiorite porphyries are high Mg# adakites, characterized by high-K calc-alkaline and metaluminous features that are enriched in LILEs (e.g., Sr and Ba) and LREEs, but depleted in HFSEs (e.g., Nb, Ta, and Ti) and HREEs. Moreover, they have enriched Sr–Nd–Hf isotopic compositions (with whole-rock (87Sr/86Sr)i ratios (0.706666−0.706714), negative εNd(t) values of −9.1 to −8.6, negative zircon εHf(t) values of −12.2 to −6.7, and two-stage Hf model ages (TDM2) between 1.5 and 2.0 Ga). However, compared to host rocks, the granodiorite porphyry with MMEs shows variable geochemical compositions, e.g., high Mg#, Cr, Ni, and V contents and enriched with LILEs. In addition, they have more depleted ISr, εNd(t), and εHf(t) values (0.706025 to 0.706269, −6.4 to −7.4, and −10.6 to −5.7, respectively), overlapping with regions of Early Cretaceous mafic rocks derived from enriched lithospheric mantle in the MLYRB. Coupled with significant disequilibrium textures and geochemical features of host rocks and MMEs, we propose that those rocks have resulted from mixing the felsic lower crust-derived magma and the mafic magma generated from the enriched mantle. The mixed magmas subsequently rose to shallow crust to form the ore-bearing rocks and facilitate Cu–W mineralization.

The purpose of this study is to optimize the the lecturing schedule using the Ant Colony Optimization (ACO) algorithm. The method developed will find an optimal solution of lecturing schedule where there are some limitations that must be considered. These limitations include being a lecturer or a class that can only be scheduled to lecture a maximum of two times in a row. Another limitation is that two adjacent level may not be scheduled at the same time, because there is a possibility that students will repeat a lecture. The third limitation is that there should be no lecturers or classes that conduct lectures with too high a frequency one day. And the fourth limitation is the alternative time where lecturers can teach will be limited due to other activities that must be carried out by the lecturer. So that the course scheduling case can be solved using the ACO algorithm, a graph is made where each node is the name of the course that must be scheduled. The path created by the ants from the initial node to the end node will contain the order of courses that must be carried out one week. Based on the test results, the ACO algorithm has succeeded in scheduling courses involving 38 subjects, 4 class forces, 6 recovery locations and 12 lecturers supporting the courses. The scheduling solution obtained has a fitness value of 0.0092. Where there are no lecturers who have a high teaching frequency one day, but there are 12 class schedules that cause a class to follow a high frequency of lectures. And there are 4 courses scheduled to be close together. This final performance is considered quite good and shows that ACO has been successfully used to optimize course scheduling.

Published: February 2020

Sabe-se da importância do impacto da religiosidade e espiritualidade (R/E) sobre a saúde mental. Entretanto, existe um grande gap entre este conhecimento e a prática de psicólogos e psiquiatras. Parte deste gap se deve à falta de treinamento dos profissionais de saúde mental em temas dessa natureza. Desta forma, este estudo tem como objetivo oferecer uma breve revisão prática de linhas psicoterapêuticas que contemplam a R/E, visando, em parte, suprir essa carência de treinamento. A partir de uma revisão da literatura, realizou-se o levantamento e a descrição das principais técnicas psicoterapêuticas que contemplam a R/E. As linhas psicoterápicas com interface com a R/E descritas neste estudo são a terapia cognitivo-comportamental (TCC), a terapia de orientação analítica e a terapia de orientação fenomenológica-existencial.

Published: February 2020

Realizar a coleta de uma história espiritual é fundamental para se adotar, cotidianamente, práticas profissionais culturalmente sensíveis. Algumas razões para se considerar essa abordagem: religião e espiritualidade (R/E) são importantes para muitas pessoas, principalmente na realidade religiosa brasileira; R/E influencia desfechos de saúde, comumente por meio de associações positivas; a coleta de dados sobre a espiritualidade pode fornecer uma compreensão mais ampla da natureza e da relação entre a R/E e a sintomatologia do paciente. Já existem roteiros desenvolvidos para facilitar a obtenção de uma história espiritual pela equipe de saúde, mas também é possível ampliá-los e adaptá-los às características próprias de cada serviço de saúde. Essa identificação adequada das necessidades espirituais é central para que os profissionais possam tomar atitudes que facilitem aos pacientes a prática de suas crenças, particularmente diante de um momento de extrema vulnerabilidade, que é o adoecer.

A New Vector Representation of Short Texts for Classification
Authors: Li Yangyang , Liu Bo
Published: February 2020

Short and sparse characteristics and synonyms and homonyms are main obstacles for short-text classification. In recent years, research on short-text classification has focused on expanding short texts but has barely guaranteed the validity of expanded words. This study proposes a new method to weaken these effects without external knowledge. The proposed method analyses short texts by using the topic model based on Latent Dirichlet Allocation (LDA), represents each short text by using a vector space model and presents a new method to adjust the vector of short texts. In the experiments, two open short-text data sets composed of google news and web search snippets are utilised to evaluate the classification performance and prove the effectiveness of our method.

The indispensable knowledge of Deoxyribonucleic Acid (DNA) sequences and sharply reducing cost of the DNA sequencing techniques has attracted numerous researchers in the field of Genetics. These sequences are getting available at an exponential rate leading to the bulging size of molecular biology databases making large disk arrays and compute clusters inevitable for analysis.In this paper, we proposed referential DNA data compression using hadoop MapReduce Framework to process humongous amount of genetic data in distributed environment on high performance compute clusters. Our method has successfully achieved a better balance between compression ratio and the amount of time required for DNA data compression as compared to other Referential DNA Data Compression methods.
Finding the “Appropriate Distance” in Egg Donor Kinship Relations
Authors: Lykkebo Petersen Matilde
Published: February 2020

This article explores kinship formation from the perspective of egg donors in Denmark. Through interviews with Danish egg donors, it investigates how the Danish legal framework and specific context, materialise egg donor kinship relations in third party reproduction. The article shows the ways egg donors negotiate normative ideals about family and motherhood through different kinship strategies. It argues that the donors’ relational kinship work is a form of social pioneering work, wherein donors help define what an egg donor kinship relation is and can be. This is analysed through the analytical concept of “appropriate distance.” The analysis shows how different normative constraints are embedded in the legal framework that structure which kinship relations are available. As an example, the different donor types in Denmark, anonymous, open, and known, become a way of disconnecting or connecting to kinship. In line with existing studies, it demonstrates how egg donation in Denmark is structured around ideals of altruism linked to normative ideals of femininity and motherhood. Further, it is concluded that egg donation proposes subversive potential for deconstructing heteronormative kinship ideals about motherhood. At the same time, however, the analyses conclude that heteronormative family ideals often are re-installed through egg donation practices.
La pedagógica de la liberación de Enrique Dussel: Inakayal y lo que la pedagogía nos negó

Published: February 2020

La Pedagógica dusseliana se desprende de la primera relación ética, que es el cara-a-cara. Esta relación se da en determinado sistema ideológico (Totalidad) que es el que selecciona lo que se transmite de una generación a otra, el legado educativo-cultural.Lo que Dussel hace en la Pedagógica es repensar esta relación cara-a-cara a partir de las formas de dominio que inaugura la llegada de los españoles en 1492 al territorio Latinoamericano, donde “el varón conquistador se transformó en padre opresor, en maestro dominador” (1980, p. 18). Ética y política se constituyen aquí en aspectos indisociables para repensar desde la filosofía de la liberación las relaciones de dominio que van desde el plano erótico familiar (madre-padre/hijx), al plano político institu-cional (maestrx/estudiante).Ahora bien, ¿qué lugar ocupa en nuestras constituciones subjetivas el origen de dominación y opresión que portamos a partir de 1492? ¿En qué medida esta pri-mera relación ética, transformada en relación de dominio y negación condiciona nuestras formas de posicionarnos geopolíticamente en esta distribución impuesta del sistema-mundo universal?En este trabajo, analizaré la vigencia crítica de los principios ético-políticos que dan origen a la pedagógica de la liberación de Enrique Dussel para resignificarlos en la postulación de una educación que revalorice lo históricamente excluido. La historia del cacique Tehuelche Inakayal, será la que dé contenido a la Pedagógica dusseliana, como parte de una reflexión ético-política de liberación situada, desde la Patagonia Argentina.

Este estudo identifica e analisa as práticas de lazer e a cultura no cotidiano da Comunidade dos Arturos, Contagem- MG. Localidade marcada por um número expressivo de escravos, o que possibilitou a resistência de manifestações culturais de origem africana. Abordamos a história e a identidade, com ênfase na apropriação que fazem em relação aos espaços da Comunidade e suas tradições. Metodologicamente utilizamos a observação e as entrevistas semiestruturadas, elaboradas a partir de três eixos norteadores: o de identificação das práticas de lazer da comunidade; identificação dos espaços e apropriação dos mesmos; identificação de práticas infantis. Compreendemos com esta pesquisa que as práticas de lazer e a relação das crianças com o brincar nestes espaços apresentam, para além do lúdico, uma identidade cultural valorizada e cultivada pela comunidade para perpetuação dos saberes de seus antepassados.
Um Estudo Comparado dos Palestras Itália de São Paulo e de Belo Horizonte (1914-1933)
Authors: Moura Rodrigo Caldeira Bagni
Published: February 2020

No presente trabalho analisaremos em perspectiva comparada o Palestra Itália, fundado em São Paulo em 1914, que após 1942 passou a chamar-se Sociedade Esportiva Palmeiras, com o Palestra Itália de Belo Horizonte, que iniciou suas atividades em 1921 e após 1942 transformou-se em Cruzeiro Esporte Clube. Nosso objetivo central será analisar comparativamente o processo de afirmação dos dois times, buscando compreender qual a importância do futebol, no processo de inserção e pertencimento dos italianos nas duas capitais mencionadas, e qual a contribuição dos Palestras para sedimentar a noção de identidade italiana, entre os membros da colônia, no período de 1914 à 1933.

Published: February 2020

Implementado em 2003 pelo Ministério do Esporte, o Programa Segundo Tempo (PST) é uma ação que têm se dedicado a formação profissional para o esporte educacional. Entre os diferentes modelos de formação ao longo do percurso dessa política, atualmente ela se organiza em uma Capacitação presencial e uma capacitação à distância (EaD) que tratam a temática de lazer entre seus conteúdos. A Capacitação EaD é o objeto de estudo deste artigo que visa contribuir para pesquisas de formação profissional de esporte e lazer. O objetivo geral é compreender a EaD do PST por seus esforços de produção e como o lazer está presente no curso. Como objetivos específicos: descrever e analisar os esforços da Capacitação EaD do PST para alcançar os Coordenadores de Núcleo (CNs); descrever e analisar como o lazer é trabalhado dentro da Capacitação EaD. Como metodologia usamos uma entrevista semiestruturada com a Gestora da Capacitação à distância do PST e a participação e conclusão no curso EaD. Concluímos que a gestão da EaD no PST produz esforços nomeados de políticos, tecnológicos e estruturais. Quanto ao lazer dentro da Capacitação EaD verificamos que ele é trabalhado em módulo próprio no ambiente da capacitação a partir de diferentes linguagens (vídeo-aula, slides, texto questões de início de debate no fórum e questões específicas no questionário de avaliação do conteúdo). Analisamos que essas repetições do lazer em diferentes formatos na EaD familiarizam os conteúdos pela estética da repetição. Contudo, essa estratégia não amplia sua potência comunicativa quando olhamos o lazer na relação entre os módulos de outros conteúdos.

Esta pesquisa, descritivo-exploratória, com abordagem qualitativa dos dados, objetivou descrever e refletir sobre a organização e o desenvolvimento das intervenções realizadas por cinco clowns voluntários, com pacientes idosos em um hospital filantrópico as percepções destes voluntários sobre suas intervenções. Foram realizadas seis observações com auxílio de uma matriz de observação sistemática e aplicadas entrevistas semiestruturadas com dois clowns. Os dados foram tratados por meio de elementos da técnica de análise de conteúdo. Evidenciou-se que a conversa, a música e o teatro constituem-se instrumentos potencializadores das manifestações lúdicas e artísticas utilizados pelo grupo; a relação dos voluntários com conteúdos artísticos e lúdicos durante a infância foi fundamental no processo da construção do ser clown e na atuação no contexto hospitalar; a autonomia no grupo e no hospital é fundamental para trabalhar a especificidade de cada clown.

Published: February 2020

Este artigo tem por objetivo refletir sobre a estruturação e/ou reorganização de espaços públicos como locais de formação permanente, de prestação de serviços públicos, de convivência social, cultural, esportiva e de lazer. Nesse contexto, entende-se como significativo o planejamento participativo, a organização e a realização nas cidades de programas sociais, culturais, educativos, esportivos e de lazer como alternativa para contribuir com a humanização da sociedade, convívio comunitário, melhoria da qualidade de vida e desenvolvimento social, em ambientes saudáveis, sustentáveis e de acesso público.

Published: February 2020

Este estudo aborda aspectos históricos e conceituais sobre monitoramento e avaliação de políticas e programas de esporte e lazer, com atenção especial ao processo de formulação e implantação do sistema de monitoramento e avaliação do programa Esporte e Lazer da Cidade. Para consecução deste objetivo, utilizamos como referência temporal, os dois mandatos do Governo Lula e o primeiro mandato do Governo Dilma, realizando uma investigação documental, seguida de levantamento bibliográfico da literatura relacionada à temática explorada. Percebe-se que, ao longo do período, diversas questões atingiram a gestão do programa e, consequentemente, influenciaram nas discussões em torno das respectivas metodologias de monitoramento e avaliação, até a criação de uma tecnologia social, o MIMBOÉ, que carece de constantes qualificações, visando à concretude das perspectivas vislumbradas em meio às diretrizes do programa.
A Televisão na Perspectiva dos Estudos do Lazer
Authors: Fonseca Juliara Lopes da
Published: February 2020

A televisão se configura como um importante meio de comunicação presente na maioria dos lares brasileiros. Por um lado, responsável pelo espetáculo diário que informa e diverte o público. Por outro, capaz de manipular informações a fim de atender interesses diversos. Compreender como a televisão é abordada dentro do contexto dos Estudos do Lazer possibilita avançar nas discussões sobre a interdisciplinaridade do campo. O presente artigo objetivou elencar e discutir as pesquisas que tratam da temática televisão dentro de periódicos vinculados ao campo dos Estudos do Lazer. Para tal, procedeu-se com um levantamento do material publicado pelas revistas Licere e RBEL que discutisse as relações entre os conceitos de lazer, indústria cultural e televisão. Ao todo foram selecionados 16 artigos. O número reduzido de trabalhos dificulta o aprofundamento das discussões e novas leituras sobre o tema pela perspectiva do lazer.
Produtivismo Versus Criatividade
Authors: Mazzei Victor Reis , Camargo Maria Cecília da Silva , Mello André da Silva
Published: February 2020

Esse ensaio reflete como a sobrecarga de trabalho tem impactado na atuação dos professores de ensino superior. Pressionados por metas e prazos, muitos docentes intensificam sua dinâmica laboral, comprometendo, com isso, suas práticas profissionais e, sobretudo, reduzindo o tempo para suas vidas pessoais, o que tem se desdobrado em prejuízo à saúde dos mesmos. Para o desenvolvimento desse artigo, empreendemos um levantamento bibliográfico baseado em autores que nos permitiram discutir o cenário acadêmico que “celebra” a produtividade e a competição entre os pares. A fim de promover um contraponto, trouxemos ao debate o Ócio Criativo, temática desenvolvida pelo sociólogo Domenico de Masi, cuja proposta teórica reside em uma conciliação entre a satisfação profissional, o aprendizado e a criatividade, na qual o tempo livre é necessário para repensar a prática e abastecer o repertório cultural.

Penggunaan teknologi dalam industri perikanan tangkap menjadi bagian yang penting dalam usaha peningkatan daya saing nelayan di kepulauan Sangihe. Perahu Katir dengan tipe pumpboat merupakan bagian dari teknologi yang paling banyak digunakan oleh nelayan lokal sebagai armada penangkapan ikan di Sangihe. Sehingga nelayan pengguna perahu katir menjadi bagian yang tak terpisahkan untuk dievaluasi tingkat kapasitasnya. Pada penelitian ini, tingkat kecangihan humanware dihitung dengan menggunakan metode teknometrik yang dikembangkan oleh UN-ESCAP. Penilaian derajat kecanggihan disesuaikan dengan penilaian kondisi pekerjaan nelayan yang memiliki perahu katir tipe pumpboat yang mencakup qualification, creativity, innovation and achievement, cooperation, ability to face the risk and discipline, sedangkan untuk pembobotan tiap kriteria dan sub kriteria menggunakan metode pairwise comparison. Hasil analisis yang diperoleh yaitu kontribusi kesiapan teknologi nelayan pengguna perahu katir di Tabukan Utara yaitu Embuhanga 0.203, Petta 0.228 dan Enemawira 0.220.  Nilai ini menunjukan bahwa kondisi nelayan di Tabukan Utara masih jauh dari angka kecanggihan yaitu 1 (satu), sehingga membutuhkan pengembangan yang besar dalam enam hal kriteria pengukuran yang diukur.The use of technology in the capture fisheries industry is an important part in efforts to increase the competitiveness of fishermen in the Sangihe islands. Outrigger boat with pumpboat type is the most widely used technology by local fishermen as a fishing fleet in Sangihe. So that the outrigger boat fishermen become an inseparable part to evaluate their capacity level. In this study, the level of humanware sophistication was calculated using the technometric method developed by UN-ESCAP. The degree of sophistication is adjusted to the assessment of the working conditions of fishermen who have an outrigger boat type pumpboat which includes Qualification, Creativity, Innovation and achievement, Cooperation, Ability to face the risk and Discipline, while for weighting each criterion and sub-criteria using pairwise comparison method. The results of the analysis obtained are the contribution of technological readiness of fishermen using the outrigger boat in North Tabukan is Embuhanga 0.203, Petta 0.228 and Enemawira 0.220. This value shows that the condition of fishermen in North Tabukan is still far from the sophistication rate of 1 (one), so that it requires a large development in the six terms measured measurement criteria.
