Introduction. Non-alcoholic fatty liver disease (NAFLD) is regarded as the hepatic expression of the metabolic syndrome, both conditions presenting similar clinical features.

Aim. The aim of this study was to evaluate, among diabetic subjects, the relationship between fatty liver load and the presence of metabolic syndrome criteria.

Methods. An observational study was conducted on 92 subjects with type 2 diabetes. We followed anthropometric measurments, lipid profile, blood pressure and the degree of hepatic steatosis using ultrasonography.

Results. The average age of the study group was 60,38 ± 10,37 years, with an approximately equal distribution by gender (48% male and 52% female). More than half of the subjects presented hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterol level. Most of the patients included in the study had varying degrees of liver fat load (only 9,89% of cases of apparently normal liver on ultrasound), and met the criteria for metabolic syndrome (81,31%). It was found that the frequency of the cases with fatty liver impairment was significantly higher in subjects with metabolic syndrome (32,43% compared to 5,88% for those without metabolic syndrome, p = 0,01) and the frequency of the cases with normal liver were significantly higher in subjects without metabolic syndrome (23,53% to 6,76%, p=0,02).

Conclusion. We can say that NAFLD is a risk factor for the presence of metabolic syndrome and it can be considered the hepatic expression of this syndrome.

Published: June 2019

Transition metals, such as chromium (Cr) and manganese (Mn) doped zinc oxide (ZnO) magnetic nanoparticles, were synthesized via sole gel auto-combustion method. The prepared magnetic (Zn1−(x+y)MnxCryO, where x, y = 0, 0.02, 0.075) nanoparticles were calcined in an oven at 6000 °C for 2 hours. The morphologies of the nanoparticles were investigated using different techniques. X-ray diffraction (XRD) analysis revealed that the hexagonal wurtzite structure of the synthesized nanoparticles was unaffected by doping concentration. The crystallite size measured by Scherrer formula was in the range of 32 nm to 38 nm at different doping concentrations. Nanosized particles with well-defined boundaries were observed using a field emission scanning electron microscopy (FE-SEM). Fourier transform infrared (FT-IR) spectra showed a wide absorption band around 1589 cm−1 in all the samples, corresponding to the stretching vibration of zinc and oxygen Zn–O bond. A blue shift in optical band gaps from 3.20 eV for ZnO to 3.08 eV for Zn0.85Mn0.075Cr0.075O nanoparticles was observed in diffuse reflectance spectra, which was attributed to the sp-d exchange interactions. The field-dependent magnetization M-H loops were measured using vibrating sample magnetometer (VSM). The VSM results revealed diamagnetic behavior of the ZnO nanoparticles which changed into ferromagnetic, depending on the doping concentration and particle size. The compositions of Zn, Cr, Mn and O in the prepared samples were confirmed by using the energy dispersive X-ray spectroscopy (EDX). Our results provided an interesting route to improve magnetic properties of ZnO nanoparticles, which may get significant attention for the fabrication of magnetic semiconductors.
Review of previous applications of innovative information technologies in construction health and safety
Authors: Mihić Matej , Vukomanović Mladen , Završki Ivica
Published: June 2019

Construction industry is one of the most hazardous industries to work in. This problem is further exacerbated by the fact that safety performance improvement is stagnating. Information technologies (ITs) are however identified as one of the most promising methods of improving the performance of construction safety. The goal of this paper was therefore to present previous research in the application of innovative ITs to the field of construction health and safety (H&S), classified by their underlying technology and application, to identify research gaps, as well as to evaluate and describe the potential of their implementation into construction safety practice. To achieve the set goals, the research consisted of identifying and studying the existing research published in the leading journals in the field of construction H&S. The review identified 72 papers dealing with development or application of innovative ITs. The research had also identified several research gaps, which have a significant impact on the construction safety practice. These gaps focus on the construction phase, while neglecting earlier project phases; industry and project levels, while neglecting construction activity and task levels; building projects, while neglecting infrastructure projects and specific hazard types, while neglecting a universal approach. Focussing research effort on these gaps would benefit all construction safety stakeholders but mostly the prominent contractors and H&S professionals. Furthermore, recommendations for directing research focus on solving the identified issues are given in this paper.
The Agon Motif: Redux. A Study of the Contest Element in Sport
Authors: Loy John W. , Morford W. Robert
Published: June 2019

The contest element of modern sport has its ancient roots in the “agon” of early Greek life. We begin with an overview of the material and historical continuities in the social development of sport, followed by a discussion of our suppositions regarding the original linkage of sport and war in terms of what we call “the agon motif”, and conclude with speculations about residuals of the agon motif in modern sport. We argue it is important to recognize that notwithstanding of the many transitions and transformations in the social development of sport since the agon of Homeric and Hellenic Greek cultures there are notable, long-standing, material and historical continuities in the structure of sport and the ethos of agonal contests. To better depict the relationships between the concepts of sport and contest, we highlight these vestiges of agon. We employ the phrase “the agon motif” to embrace both the concept of “agon”and the concept of “aethlos”. In a structural sense the agon motif refers to the overall properties, processes, and products of agonal competition, including contestants, spectators, battle grounds, sporting venues, festivals and spectacles, prizes and award ceremonies. Whereas, in an ideational sense, the agon motif refers to the ethos of chivalric competition associated with the pursuit of prestige (status-honor) and the active quest to achieve excellence (bodily and moral) through physical prowess in agonal contests wherein individuals place their reputation, moral character, and at times, their very lives at stake. There is a close link to the cult of masculinity and masculine domination in the Western world, since the primary avenues of pursuing the agon motif through war and sport are two of the most highly and rigidly “gendered” activities in the history of humankind. We suggest that the most fundamental dynamic of the agon motif as well as the most enduring residual of the agon motif in modern sport is the pursuit of prestige, honor and excellence through physical prowess. The ethical framework of archaic (heroic) agon represents the epitome of a morality of honor and an ethics of virtue and offers a largely unfamiliar picture from a contemporary viewpoint of winning and losing in sport.
Agon Lost – or in Disguise? A Commentary
Authors: Ballisager Olav
Published: June 2019

Thanks to John W. Loy one of the recurrent themes in Institute of Scandinavian Physical Culture (ISPC) was “agon”. First, I offer some old Nordic examples on games – possibly with an agonal element. Then I focus on moral and character in order to identify some sort or a vestige of agon and revisit physical culture in terms of “idræt”, an old Nordic word for athletics and sport. Finally, I ask if there is – atavistic or not – in the modern world any glimpse of agonal behavior to be found and appreciated within the three realms or categories, which could be pillars of a physical education program: Nature, combat/competition and aesthetics. Would Edmund Hillary, Nelson Mandela and Pussy Riot qualify into a renewed, more general perception of agon?
Why a Focus on Sporting Tests Would Reveal an Alternate Story and Raise Ethical Questions about Agon: A Commentary
Authors: Kretchmar R. Scott
Published: June 2019

Loy and Morford focus on “agon” as an important window through which to understand human life and development. Competition in war and sport was culturally significant then, and it is culturally significant today, albeit in modified forms. In this commentary, I attempt to do two things – first, identify implications of some conceptual distinctions, and second, point out normative questions raised by the Loy/Morford analysis. I find it worthwhile to differentiate clearly between tests and contests. If the historical and sociocultural spotlight were turned on sporting “tests” rather than “contests”, that is, on trying to solve physically demanding problems well rather than trying to solve them better than at least one other party, then another story than the agonal account could be told. War would probably no longer serve as the best historical and prehistorical analogue for sport. Rather, it might be hunting. I add, that, on one hand, competitive sport is far less violent and, therefore, far more defensible today than it was previously. On the other hand, joy in playing is often sacrificed on the altar of any number of extrinsic rewards. Success, even gained by questionable means, replaces skill-based and virtue-generated achievement. This threatens the connection endorsed by MacIntyre between practices and virtues.
Analysis of Transients in a Three-Level DC–DC Flying Capacitor Converter. Time Domain Approach
Authors: Reznikov Boris , Ruderman Alexander , Galanina Valentina
Published: June 2019

The paper considers a discrete state-space model for transients in a three-level flying capacitor DC–DC converter. A transition matrix is obtained for a pulse width modulation (PWM) period. The matrix elements are expanded into a power series using a selected small parameter. The matrix eigenvalues that determine the natural balancing dynamics transients are presented in the form of power series as well. Four separate transients are constructed based on four possible PWM period initial states (topologies). Inductor current and capacitor voltage transients are found for the voltage source power-up as the arithmetic average of the four separate transients. The discrete solutions are replaced by continuous ones. The resulting transients that are elementary functions of the circuit parameters, PWM period, and voltage reference demonstrate good agreement with the simulation results.

Authors: Kuhelj Dimitrij , Dobrovolec Anita , Kocijancic Igor Jozef
Published: June 2019

Background

Percutaneous image-guided intradiscal injection of gelified ethanol was introduced to treat herniated disc disease lately. The aim of the study was to assess clinical efficacy and durability over a 36 months’ period.

Patients and methods

Eighty-three patients (47 males, 36 females, mean age 48.9 years (18–79 years) were treated between May 2014 and December 2015 for 16 cervical and 67 lumbar chronical contained disc herniations. For pain assessment evaluation, the visual analog scale (VAS) was used. Physical activity, the use of analgesics, patients’ satisfaction with the treatment results and patient’s willingness to repeat the treatment were also evaluated.

Results

Fifty-nine patients responded to questionnaire. 89.8% had significant reduction in VAS after 1 month (p < 0.001); 76.9% of patients with cervical symptoms and 93.5% of patients with lumbar symptoms. In cervical group it remained stable, while in lumbar group VAS decreased even more during 36 months (p = 0.012). Single patient had spinal surgery. Moderate and severe physical disability prior to treatment (96.6%) was reduced to less than 30% after 12 months. The majority of active patients returned to their regular job (71.1%); 78% needed less analgesics. Only 5.1% patients were not satisfied with the treatment and 10.2% would not repeat the treatment if needed.

Conclusions

Percutaneous image-guided intradiscal injection of gelified ethanol is safe, effective and durable therapy for chronic contained cervical and lumbar herniations. Due to minimal invasiveness and long-lasting benefits, this kind of treatment should be proposed to designated group of patients as first-line therapy.
Contexts of children’s well-being. Integrating urban development by the municipal smallscale monitoring instrument UWE
Authors: Petermann Sören , Strohmeier Klaus Peter , Yaltzis Katharina
Published: June 2019

This article presents results of a pilot-study, which developed a monitoring-instrument for measuring well-being of children and young people in a municipal permanent observation and as evaluation tool. Integrated urban development faces the challenge to absorb negative consequences at the development of children by residential and educational segregation. At the same time, in cities there is a lack of systematic available small-scale data about children in the middle years. The instrument uses human resources as necessary potential for society and measures areas of children’s development strongly linked to well-being and the influence by the socio-spatial contexts: family, school and living environment. A simultaneous testing of these contexts allows options of intervention, which can be used resource-specific.
Effects of Surrounding Earth on Shell During the Construction of Flexible Bridge Structures
Authors: Machelski Czesław
Published: June 2019

A characteristic feature of soil-steel structures is that, unlike in typical bridges, the backfill and the carriageway pavement with its foundation play a major role in bearing loads. In the soil-steel structure model, one can distinguish two structural subsystems: the shell made of corrugated plates and the backfill with the pavement layers. The interactions between the subsystems are modelled as interfacial interactions, that is, forces normal and tangent to the surface of the shell. This is a static condition of the consistency of mutual interactions between the surrounding earth and the shell, considering that slip can arise at the interface between the subsystems. This paper presents an algorithm for determining the internal forces in the shell on the basis of the unit strains in the corrugated plates, and subsequently, the interfacial interactions. The effects of loads arising during the construction of a soil-steel bridge when, for example, construction machines drive over the structure, are taken into account in the analysis of the internal forces in the shell and in the surrounding earth. During construction, the forces in the shell are usually many times greater than the ones generated by service loads. Thus, the analytical results presented in this paper provide the basis for predicting the behaviour of the soil medium under operational loads.
What Is Contemporary, After All, in the Contemporary Theatre Performance?

The Processualism of the Creative Approach in an Artistic Context
Authors: Strâmtu Adrian
Published: June 2019

The following article attempts a discussion concerning the issue of creativity in the context of artistic approaches, by taking into consideration the central concepts: creative personality, creative process, and creative product/ creative performance. Our analysis is based on two questions that concern the extent to which we can speak of flexibility and creativity in contemporary artistic activities. Our conclusion is that creative artistic activities are not disorderly/ unorganised, they are realised according to artistic rules and principles that relate to the forms of expression that can be used in creative artistic approaches. Furthermore, in the context of the cultural hybridization phenomenon, the merging of the traditional with the postmodern allows the manifestation of cultural and artistic diversity, as well as the revaluation, redefinition and update of the traditional forms of expression and of cultural forms in a creative manner, by means of a creative exploitation of their spectacular artistic potential.
Barnardine or Death as an Option
Authors: Ionescu Romanița
Published: June 2019

The aim of this article is to research the meaning of the presence in the play Measure for Measure by William Shakespeare of a character which apparently doesn’t fulfill any dramatic function. Although the drunkard Barnardine seems to be brought into the scene in order to make possible the salvation of Claudio, the brother of the main feminine character, through the dramatic mechanism of replacing one man sentenced to death with another, Shakespeare surprisingly quits this solution. Barnardine is spared because he has strongly drunk all night long and, as a consequence, he doesn’t feel prepared to die. In this manner, this minor character approaches, during only one page of text, some fundamental themes of Shakespearian writing: preparation for death, and sleep and inebriation as paradoxal states of the conscience. Barnardine floats in three dimensions: inebriation, dream, and reality. This state of chiaroscuro of the conscience reveals the negative of the being, it opens the gate to the realm of the shadow. In this state, Barnardine chooses not to die and the Duke, the demiurge of the play, spares his life. Barnardine exists in a dimension where the laws of the real loosen their rigidity and death can be an option, not a necessity.

Given the relationship of sustainability and mutual benefits that tourism and cultural heritage can and should establish, the present study aims to reflect on the importance of the development of creative activities in the Castle of Lanhoso, in the municipality of Póvoa de Lanhoso (in northern Portugal), as a form of promotion and tourism valorisation of this heritage classified as National Monument. In this context, the study intends to stimulate and streamline the processes of monetization and preservation of the Castle of Lanhoso, making it suitable for sustainable tourism economic activity with the purpose of improving the living conditions of the population, generating employment and revenues, increasing tourism demand, promoting and preserving the identity and the local cultural heritage.
Phage Therapy Against Biofilm of Multidrug-Resistant Klebsiella Pneumoniae Isolated from Zakho Hospital Samples
Authors: AlBany Yousif Abdullah , Al-Berfkani Mohammad Ismail , Assaf Mahde Saleh
Published: June 2019

Klebsiella pneumoniae causes infection in human, especially in immunocompromised patients. About 80% of nosocomial infection caused by K. pneumoniae is due to multidrug-resistant strain. The emergence of antibiotic-resistant bacterial strains necessitates the exploration of alternative antibacterial therapies, which led to studying the ability of viruses that infect the bacteria (known as bacteriophage) to treat infection with K. pneumoniae. Bacterial biofilm which are crucial in the pathogenesis of much clinically important infection and are difficult to eradicate because they exist resistant to many antimicrobial treatment. Biofilm formation by K. pneumoniae is responsible for the catheter associated infection such as urinary tract infection and respiratory tract infection due to the colonization of the polymeric surface by forming multilayered cell cluster embedded in extracellular materials. In this study K. pneumoniae isolated from the hospital environment and characterized it and form the biofilm of that organism by microplate quantitative assay. Similarly bacteriophage specific for K. pneumoniae isolated from river water. The aim of work is the use of bacteriophage as a possible alternative for the treatment of bacterial infection of K. pneumoniae. We showed that biofilm is reduced by isolated phages by the comparative account of colony-forming unit versus plaque-forming unit. The result of this study, therefore, suggests that the timing of starting the phage therapy after initiation of infection significantly contributes toward the success of the treatment.
The Dual Role of Histidine as General Base and Recruiter of a Third Metal Ion in HIV-1 RNase H
Authors: Dürr Simon L. , Bohuszewicz Olga , Suardiaz Reynier , Jambrina Pablo G. , Peter Christine , Shao Yihan , Rosta Edina
Published: June 2019

RNase H is a prototypical example for two metal ion catalysis in enzymes. An RNase H activity is present in the HIV-1 reverse transcriptase but also in many other nucleases such as Homo sapiens (Hs) or Escherichia coli (Ec) RNase H. The mechanism of the reaction has already been extensively studied based on the Bacillus halodurans (Bh) RNase H crystal structures, most recently using time-resolved X-Ray crystallography. However, kinetic and mutation experiments with HIV-1, Hs and Ec RNase H implicate a catalytic histidine in the reaction that is not present in Bh RNase H, and the protonation of the leaving group also remains poorly understood. We use quantum mechanics/molecular mechanics (QM/MM) calculations combining Hamiltonian replica exchange with a finite-temperature string method to study the cleavage of the ribonucleic acid (RNA) backbone of a DNA/RNA hybrid catalyzed by the HIV-1 RNase H with a focus on the proton transfer pathway and the role of the histidine. The reported pathway is consistent with kinetic data obtained with mutant HIV-1, Hs and Ec RNase H, the calculated pKa values of the DEDD residues and crystallographic studies. The overall reaction barrier of ∼18 kcal mol-1, encountered in the first step, matches the slow experimental rate of ∼1-100 min-1. Using Molecular dynamics (MD) calculations we are able to sample the recently identified binding site for a third transient divalent metal ion in the vicinity of the scissile phosphate in the product complex. Our results account for the experimental observation of a third metal ion facilitating product release in an Aquifex aeolicus RNase III crystal structure and the Bh RNase H in crystallo reaction. Based on our data we are able to show that the third ion and the histidine are key to product release as had been hypothesized.
Concise Synthesis of GB22 by Endo-Selective Siloxycyclopropane Arylation
Authors: Burdge Hannah E. , Oguma Takuya , Kawajiri Takahiro , Shenvi Ryan
Published: June 2019

The first synthesis of GB22 was accomplished by a con- cise, modular route. Two building blocks converged in a novel sp3-sp2 attached-ring coupling that used Ir/Ni dual-catalysis to reverse the regioselectivity of siloxycy- clopropane arylation. This cross-coupling proved general to access β-substituted tetralones via ring-expansion of indanone-derived siloxycyclopropanes. The congested, bridging rings of the GB alkaloids were completed using an aluminum-HFIP complex that effected intramolecular cyclization of an acid-labile substrate.
Nickel-Catalyzed Regioselective Hydroalkylation of 1,3-Dienes with Hydrazones
Authors: Lv Leiyang , Zhu Dianhu , Qiu Zihang , Li Jianbin , Li Chao-Jun
Published: June 2019

Hydroalkylation of unsaturated hydrocarbons with unstablized carbon nucleophiles is difficult and remains a major challenge. The disclosed examples so far mainly focused on the involvement of heteroatom and/or stabilized carbon nucleophiles as efficient reaction partners. Reported here is an unprecedented regioselective nickel-catalyzed hydroalkylation of 1,3-dienes with hydrazones, generated in situ from abundant aryl aldehydes and ketones and acted as both the sources of unstabilized carbanions and hydride. With this strategy, both terminal and sterically hindered internal dienes are hydroalkylated efficiently in a highly selective manner, thus providing a novel and reliable catalytic method to construct challenging C(sp3)-C(sp3) bonds.

Non-Hodgkin's lymphomas are characterized by its clinical and pathological polymorphism. In the stomach, MALT lymphomas are common and mostly associated with Helicobacter Pylori infection. We report a case of 76-year old women with a medical history of chronic stomach pain, addressed for the investigation of normochromic normocytic anemia. The clinical picture included signs of digestive hemorrhage and stomach pain. Gastrointestinal endoscopy and histology noted an unspecified ulcer-budding tumor without signs of Helibacter pylori infection. Immunohistochemistry concluded to diffuse large B cell lymphoma with CD79b +, BCL10 +/-, BCL2+, BCL6 +, MUM1+. The Ann Arbor classification was  stage IE. The serology of Helicobacter pylori was negative. Pre-treatment investigation noted a comorbity with Hepatitis C infection. This study has two interests. Firstly the rarity of the localization of this lymphoma, and secondly, the etiopathological interest because of association with hepatitis C virus.
Condições de trabalho e repercussões pessoais e profissionais dos envolvidos com a pós-graduação stricto sensu: balanço e perspectivas
Authors: Bianchetti Lucídio
Published: June 2019

Apesar das críticas ao sistema Capes, não se registram movimentos com potencial de abalá-lo. Manifestações diversas e pesquisa evidenciam que, a despeito de discordâncias, os envolvidos com a pós-graduação (PG) tudo fazem para (re)ingressar ou manter-se no sistema. Constatam-se prejuízos à produção e veiculação do conhecimento e às condições de vida/trabalho daqueles que atuam na PG. No entanto, uma espécie de naturalização parece estar garantindo a manutenção do modelo de avaliação e financiamento, caracterizado mais como uma política de estado do que de governo. Neste texto, além de tratar de algumas destas questões, destacamos avanços decorrentes da implementação desse sistema, bem como o aprofundamento de aspectos que deixam a desejar, em especial nas Ciências Humanas e Sociais.
É a educação ética uma forma de violência contra o educando?
Authors: Pucci Bruno
Published: June 2019

Chauí, no livro Convite à Filosofia lança uma questão instigante para os educadores: não seria a educação ética uma forma de violência contra o ser humano? Primeiramente, porque visa transformar-nos de seres passivos em ativos; se nossa natureza é passional, impulsionada por nossos instintos, forçar-nos à racionalidade ativa não seria violência contra a natureza espontânea? Se a educação ética se propõe a colocar-nos em conexão com os valores da sociedade, não seria isso submissão ao poder externo e, nesse caso, em vez de sujeitos autônomos, não seríamos escravos das normas e valores impostos pela sociedade? Este texto se propõe, a partir das contribuições de Kant, Durkheim e Adorno, analisar os questionamento de Chauí e trazer contribuições para a formação ética de nossos educandos e educadores.

As múltiplas interfaces entre o global e o local na educação ambiental demandam a construção de práticas de formação de professores nas quais estes participem ativamente do processo, fornecendo subsídios para a realização das atividades. Com essa perspectiva, o presente texto discute os pressupostos subjacentes à realização de ações calcadas nos âmbitos conceituais, atitudinais e procedimentais, indicando a necessidade de incluir a diversidade de experiências dos professores na construção de práticas compartilhadas de formação continuada. Aborda-se, ainda, a importância da inserção de estudos teóricos específicos no âmbito das ciências da natureza em sintonia com o nível de ensino no qual os professores atuam.
Novas perspectivas de avaliação do aluno de EaD no paradigma da cibercultura e a web 2.0
Authors: Junqueira Eduardo
Published: June 2019

O trabalho discute contribuições oferecidas pelos paradigmas da cibercultura e da Web 2.0 às formulações sobre a avaliação da aprendizagem do aluno, em particular na modalidade da educação a distância, EaD. Parte-se de uma reflexão sobre os avanços e limites da avaliação em EaD para a proposição de sua expansão a fim de abarcar ações do aluno relacionadas ao processo de navegação e aprendizagem no ciberespaço. Argumenta-se que tais ações extrapolam os limites do ambiente virtual de aprendizagem e estão relacionadas às novas práticas de interação, colaboração, coautoria e apropriação criativa vivenciadas por muitos alunos. Novas formas de avaliação permitem atribuir valor a essas ações e elevar a qualidade dos processos de aprendizagem.
Paulo Freire está vivo no movimento da educação popular
Authors: Rossel Nélida Cespedes
Published: June 2019

O artigo é uma reflexão acerca da relevância da contribuição de Paulo Freire e da educação popular e sua perspectiva crítica e transformadora para o atual momento histórico de crise social, econômica, educativa e ambiental. É um ponto de vista do Conselho de Educação de Adultos da América Latina (CEAAL), que, como uma rede, articula vários processos socioeducativos, com organizações de base e outras redes. E procura modificar as situações que não permitem condições humanas e sociedades justas. A contribuição de Paulo Freire é significativa, por seu pensamento político, ético e educativo a partir da atual leitura do contexto, para daí ressignificar o sentido da educação e sua colaboração para a construção de outro mundo possível.
“Professor, quero ser oprimida!”: situação-limite e atos-limites no habitus professoral
Authors: Sousa Carlos Alberto Lopes de
Published: June 2019

Esse artigo tem por objetivo apresentar e discutir episódio ocorrido no ensino superior em que estudante, tendo estudado a Pedagogia do Oprimido (Freire, 1987), demanda explicitamente a condição de ser oprimida pelo professor. O episódio registrado em diário de campo é analisado sob a ótica dos conceitos de situação-limite, inédito-viável, ambos de Paulo Freire (1992), e o de habitus, este último conceito de Bourdieu (1983). O conceito de habitus é posicionado no texto em perspectiva heurística, sendo denominado habitus professoral, nos termos de Silva (2003). O texto conclui que o pensamento freireano deve ser assumido como utopia sustentada no habitus professoral, expressando a negação do fugaz ou insatisfação momentânea e associado a movimento coletivo pela superação do estado das coisas e condições de existência desumanizadoras.
Sobre a narrativa como categoria analítica da avaliação escolar
Authors: Suassuna Lívia
Published: June 2019

Neste estudo, discutimos a prática da avaliação no campo da linguagem. Na primeira parte, mostramos os limites das práticas avaliativas centradas numa concepção de linguagem como estrutura e de avaliação como mensuração. Na segunda, expomos algumas ideias do autor em cujo pensamento nos baseamos para a reconceptualização da avaliação; trata-se de Walter Benjamin, especificamente do livro Magia e técnica, arte e política – ensaios sobre literatura e história da cultura. Na terceira, mostramos como o processo de ensino pode ser entendido como narrativa e o professor, como um narrador, na perspectiva da avaliação enquanto ação discursiva a serviço da aprendizagem e da qualidade da educação.

Published: June 2019

Este trabalho tem como objetivo evidenciar as principais concepções e tendências dos sistemas de avaliação de desempenho docente nas redes estaduais de educação básica no Brasil. A discussão do tema tratou da relação entre avaliação, responsabilização e desenvolvimento profissional, bem como das concepções que orientam os processos avaliativos de desempenho docente.  As análises do levantamento realizado a partir das informações disponíveis nos sítios das 27 Secretarias Estaduais de Educação revelaram que, nos estados brasileiros, a tendência predominante nas políticas de avaliação docente se dá na perspectiva da responsabilização, na maioria das vezes se utilizando dos resultados de avaliações do desempenho de alunos, que se distanciam dos pressupostos que orientam o processo de desenvolvimento profissional docente.

RELATIONSHIP BETWEEN SLEEP HYGIENE AND SLEEP QUALITY IN ADOLESCENTS AGED 12-15 YEARS
Authors: Muharyani Putri Widita
Published: June 2019

ABSTRACT

Background: Good sleep is necessary for adolescents to maintain optimum health and cognitive function. Adolescents have a unique sleep behavior owing to the several hormonal changes they undergo and the variations in the circadian rhythms that regulate the sleep-wake cycle. One method for treating sleep problems in adolescents is ensuring sleep hygiene. We aimed to determine the relationship between sleep hygiene and sleep quality in adolescents aged 12–15 years at Junior High School 1 Indralaya. Methods: This study used a cross-sectional design. Samples were collected from 97 adolescents using the proportionate stratified random sampling technique with questionnaires. The data were analyzed using Chi Square test. Results: There was a significant relationship between sleep hygiene and sleep quality (ρ -value < 0.05). Sleeping is crucial for adolescents to maintain their performance in several activities, including the achievement of optimal learning outcomes. A superior sleep hygiene behavior will improve sleep quality. Conclusion: Provision of health education about sleep hygiene to adolescents by health workers is important for improving the adolescents sleep quality.

Population explosion was not a grave problem in the early days of Islam or in the period of Islamic legislation. Thus, no explicit negation or affirmation of it is available either in the religious texts or in the religious jurisprudence or law. That is why presently the ulema from both the ends  the opponents as well as the proponents of family planning, extract some selective Quranic verses, Ahadith and inferences of jurisprudence in favour of their respective viewpoints. Such diverging views have made the future of family planning programmes doubtful in Pakistan. With this background, the present study shows that in the contemporary situation, it is solely the individual who makes the final decision about approving or disapproving family planning. This decision-making process is influenced by the personal attributes of the practitioners. In order to evaluate these attributes, the researcher has attempted to analyze and highlight the perception of family planning by Muslim residents of Islamabad i.e. the Capital city of Pakistan. The people surveyed are predominantly from different social, geographical and economic backgrounds and from different religious callings, along the sectarian continuum. The researcher’s task has thus been to observe the responses and to point out whether the objective variables i.e. geographical, income and class, occupation and age factors etc. are more significantly associated with knowledge, attitude and practice of family planning or the subjective variables like religion and sect appear to be more important determining factor of family planning practice in a traditional society like that of Pakistan.

Цель. Изучение исходного уровня маркеров повреждения миокарда (МПМ), показателей кислородного бюджета и их связи с параметрами гемодинамики у пациентов с недостаточностью митрального клапана (НМК).

Материалы и методы. Обследованы 85 пациентов с НМК, которые на момент госпитализации были разделены на две группы с последующим выполнением операции протезирования митрального клапана. Во время госпитализации измеряли уровни МПМ, показатели кислородного бюджета, проводили корреляционный анализ полученных данных и показателей глобальной продольной деформации (ГПД) миокарда, фракции выброса левого желудочка, сердечного индекса.

Результаты. В обеих группах обследованных пациентов между показателями натрийуретического пептида и ГПД миокарда выявлена сильная связь, между показателями натрийуретического пептида и фракции выброса левого желудочка - значительная связь. Уровни аланинаминотрансферазы и аспартатаминотрансферазы, креатинфосфатазы и МВ-фракции креатинфосфокиназы тесно коррелировала с величинами ГПД. В то же время связи показателя ГПД с величиной отношения МВ-фракции креатинфосфокиназы к креатинфосфокиназе не обнаружено.

Выводы. У пациентов с НМК не наблюдается признаков повреждения миокарда, но чем более выражены нарушения внутрисердечной гемодинамики, тем вероятнее развитие повреждения миокарда при его перегрузке.

Мета. Оцінити результати застосування рентгенендоваскулярної селективної електрокоагуляційної оклюзії судин наднирника в лікуванні феохромоцитоми.

Матеріали і методи. Проведено проспективне та ретроспективне дослідження результатів лікування 66 пацієнтів, яким виконали лапароскопічну адреналектомію (ЛА) з приводу феохромоцитоми за період з 2008 по 2018 р. Для порівняльного аналізу пацієнтів розподілили на дві групи: 1-ша група - 36 пацієнтів, яким за 24 год до ЛА виконували рентгенедоваскулярну селективну електрокоагуляційну оклюзію (РЕВСЕО) судин наднирника, 2-га група - 30 пацієнтів, яким виконали тільки ЛА. Проаналізовано середню тривалість оперативного втручання, об’єм крововтрати, гемодинамічні параметри, рівень метанефрину в сечі та ускладнення.

Результати. За віком, статтю, локалізацією та розміром пухлини суттєвої різниці між обома групами хворих не було. Об’єм інтраопераційної крововтрати у пацієнтів 1-ї групи становив (50 ± 5,78) мл, 2-ї групи - (105,48 ± 84,41) мл (p < 0,00001). Під час госпіталізації середній рівень метанефрину в сечі у хворих 1-ї та 2-ї груп практично не відрізнялися - (1163,54 ± 931,5) мкг/24 год (153,0 - 4011,0 мкг/24 год) та (1097,69 ± 903,28) мкг/24 год (146,5 - 3350 мкг/24 год) відповідно (р=0,254), проте через 24 год після РЕВСЕО судин наднирників середній рівень метанефрину в сечі у пацієнтів 1-ї групи суттєво зменшився та становив (315,64 ± 111,51) мкг/24 год (108 - 614,51 мкг/24 год, р=0,00001). Тривалість оперативного втручання у хворих 1-ї та 2-ї груп була майже однаковою - відповідно (110,8 ± 44,88) та (113,3 ± 55,42) хв (p = 0,515). Гемодинамічну нестабільність спостерігали лише у 5 (16,7%) пацієнтів 2-ї групи. Ускладнення виникли у 4 (13,3%) пацієнтів 2-ї групи та у 1 (2,8%) пацієнті 1-ї групи. В обох групах жоден пацієнт не помер.

Висновки. У порівнянні з ЛА мультидисциплінарний підхід є більш безпечним, швидким та ефективним у лікуванні пацієнтів з феохромоцитомою.
Юридичні аспекти лікарських помилок у хірургічній практиці
Authors: Biliakov A. M. , Erhard N. M. , Kobylianskyi O. L.
Published: June 2019

Мета. Аналіз лікарських помилок та їх судово-медичної складової, що є основною для визначення міри кримінальної відповідальності лікаря-хірурга у разі спричинення шкоди здоров’ю пацієнта.

Матеріали і методи. Методологічною основою роботи стали системно-структурний та порівняльний аналіз лікарських помилок у медичному та правовому аспектах, обґрунтування понять «лікарська помилка», «нещасний випадок» та «професійний злочин». Розглянуто положення та сформульовано висновки, які ґрунтуються на широкому нормативному, науково-теоретичному і практичному матеріалі.

Результати. Помилки в медичній практиці досить поширені, навіть у розвинених країнах світу. Судова практика щодо цієї категорії справ узагалі не оприлюднюється, що не лише негативно впливає на збільшення кількості лікарських помилок, а й дає лікарю можливість відчувати впевненість у своїй безкарності. В Україні професійна діяльність лікаря-хірурга регламентована відомчими наказами, стандартами та правилами надання медичної допомоги, а також окремими статтями Кримінального кодексу України, в яких йдеться про особливості та специфіку медичної діяльності та пов’язану з нею кримінальну відповідальність, і лише стаття 140 стосується будь-якого лікаря, у тому числі й хірурга.

Висновки. На нашу думку, актуальною та обґрунтованою є пропозиція багатьох фахівців у галузі медичного права щодо необхідності визнання лікарської помилки юридичною категорією і внесення її до чинного законодавства. Саме тоді, коли лікарська помилка стане складовою нормативно-правової бази медичної діяльності, пацієнти та лікарі матимуть можливість повноцінно захищати себе в суді.

Biofouling merupakan akumulasi pertumbuhan dari organisme laut yang hidupnya menempel pada material terendam oleh air laut. Akumulasi biofouling yang terjadi secara berkelanjutan dapat menimbulkan masalah baik secara ekonomis dan operasional khususnya pada kapal yang digunakan sebagai alat transportasi. hal ini dapat menyebabkan kecepatan kapal berkurang hingga 40% sehingga konsumsi bahan bakar meningkat sampai dengan 30%. Penelitian ini bertujuan mengetahui pengaruh penambahan ekstrak larutan kulit mangrove pada cat minyak sebagai antifouling. Hasil penelitian menunjukan bahwa penambahan ekstrak larutan kulit mangrove memiliki pengaruh terhadap jumlah penempelan biofouling.  Hal ini dapat dilihat dari data yang didapatkan dimana pada material bahan uji yang menggunakan campuran tanin lebih sedikit terjadi penempelan pada material yaitu sebanyak 4 individu, sedangkan jika dibandingkan dengan sampel uji yang tidak menggunakan campuran tanin jumlah yang terdata sebanyak 9 individu.
