Authors: ÖZTÜRK Gökhan , ÖZTÜRK Özlem
Published: September 2019

Bu araştırmanın amacı, müzik öğretmenlerinin
öğretmen yeterlikleri alanlarına ilişkin hizmetiçi eğitim ihtiyaçlarını
saptamak ve bu ihtiyaçların cinsiyet, çalışılan kurum ve çalışma süresine göre
ne tür farklılıklar gösterdiğini belirlemektir. Tarama modeline göre
yapılandırılan çalışma, Tokat il merkezinde görevli 48 müzik öğretmeni ile
yürütülmüştür. Veriler, Çiftci’nin (2008) geliştirdiği anket yoluyla toplanmıştır. Verilerin
çözümlenmesinde, aritmetik ortalama ve standart sapma değerleri,
karşılaştırmalarda ise bağımsız t-testi, tek yönlü varyans analizi ve Kruskal-Wallis testi kullanılmıştır.
Araştırma sonucuna göre; müzik öğretmenleri, öğretmen yeterlikleri alanlarında farklı konularda ve farklı
yoğunluklarda hizmetiçi eğitime ihtiyaç duymaktadır ve bu ihtiyaçlar cinsiyet, çalışılan kurum ve mesleki tecrübeye
göre farklılaşmamaktadır. Öğretmenlerin hizmetiçi eğitim ihtiyaçlarının, müzik alan bilgisi
konularında yoğunlaştığı, bu ihtiyacı genel kültür konularının izlediği, meslek
bilgisi konularında ise hizmetiçi eğitim ihtiyaçlarının göreceli olarak daha
düşük olduğu belirlenmiştir. Öğretmenlerin ihtiyaçları, müzik alan bilgisi
alanında sırasıyla; armoni-kontrpuan-eşlik, okul çalgıları, eşlik çalma, Türk
müziği çokseslendirme ve çalgı bakım-onarım bilgisi konularında; genel kültür
alanında, müzik eğitiminde bilgisayar ve teknoloji konusunda; meslek
bilgisi alanında ise özel öğretim yöntemleri, öğretim
teknolojileri ve materyal tasarımı, öğretim ilke ve yöntemleri, rehberlik ve
eğitim psikolojisi konularında yoğunlaşmaktadır.
Çalışma sonunda, müzik öğretmenlerinin hizmetiçi eğitim beklentilerinin
gerekçeleri tartışılmıştır.

Published: September 2019

Analisa as ideias e a atuação de Anísio Teixeira nos anos 1920 e
1930, focalizando as suas concepções acerca do valor da mensuração
para a renovação educacional no Brasil. Considerando que o pensamento
e as práticas de Teixeira devem ser compreendidos no contexto em
que se desenvolveram, apresenta um histórico da inserção dos saberes
psicológicos na educação, com especial atenção para a adesão do
movimento escolanovista à Psicometria. Conclui que, ao defender o uso
da mensuração, Teixeira se manteve fiel à meta da Escola Nova que exigia
diagnosticar cientificamente o universo escolar, o que se fazia necessário
para responder à crescente demanda por escolarização e às deficiências
das instituições de ensino brasileiras.

Analisa o ensino multisseriado de uma escola localizada na zona rural de Cruzeiro do Sul, no Estado do Acre, onde as aulas do 1º ao 5º ano são ofertadas numa mesma sala. Realizamos entrevistas, observações in loco e análise documental para verificar se a disposição da sala de aula, em fila por série, prejudica a aprendizagem e para identificar as dificuldades dos alunos no ensino multisseriado. Refletimos sobre a educação rural, o ensino multisseriado e a mediação docente para trabalhar conceitos e conteúdos diversos desde a alfabetização até o 5º ano do ensino fundamental, na perspectiva histórica e cultural. Concluímos que existem possibilidades de aprendizagem nos modelos multisseriados de ensino, mas há lacunas, apesar de o professor se desdobrar para ensinar e produzir conhecimento nas salas multisseriadas.
Políticas de material didático no Brasil: organização dos processos de escolha de livros didáticos em escolas públicas de educação básica
Authors: Zambon Luciana , Terrazzan Eduardo
Published: September 2019

Apresenta os resultados de estudo sobre os processos de escolha de livros didáticos (LD), no âmbito do Programa Nacional do Livro Didático (PNLD), mediante o qual buscamos responder a seguinte questão: Como escolas de educação básica (EEB) organizam e desenvolvem ações para a escolha de LD? Para a coleta de informações, realizamos entrevistas com membros das equipes gestoras de 15 EEB. Pelas análises das entrevistas realizadas, podemos afirmar que: 1) a organização do processo de escolha de LD nas EEB foi desencadeada muito mais por ações desenvolvidas pelas editoras do que propriamente por orientações do Fundo Nacional de Desenvolvimento da Educação (FNDE); 2) no processo de escolha de LD, é bastante comum a realização de encontros breves durante o intervalo das aulas, no qual os professores costumam tomar suas decisões acerca da seleção dos livros; 3) as ações desenvolvidas nas EEB mobilizam todos os professores, mediante a realização de, ao menos, uma reunião, mas essas ações restringem-se à tarefa de escolha dos LD em cada área disciplinar, não havendo discussões mais amplas acerca das finalidades próprias do ensino médio, nem acerca do papel dos LD para tanto.

A long-term outlook on Russian oil industry facing internal and external challenges
Authors: Kapustin Nikita O. , Grushevenko Dmitry A.
Published: September 2019

Russian petroleum industry plays a vital part in both the country’s economy and international hydrocarbon market, providing a third of state budget revenues and over 13% of global liquid hydrocarbon exports. Yet, nowadays the industry is facing a number of serious challenges, which threaten to undermine its sustainability. These challenges include depletion of the conventional oil resources, technological and economic sanctions and stagnating demand for liquid fuels, especially apparent in Russian traditional export destinations – Europe. The authors attempted to evaluate the impact of these issues and compile a forecast of Russian oil industry using state-of-the-art modelling tools. The calculations show, that even under fairly negative scenario assumptions, Russia is capable of maintaining crude oil and refined products exports above 250 mtoe up to 2040, remaining the world’s second liquid hydrocarbon supplier. This, however, is still a huge drop from 425 mtoe of exports in 2018. To ensure sustainability the government and oil companies need to work in conjunction in several fields: facilitate geologic survey of conventional and promising oil and gas basins; domestic development of new oil extraction technologies for accessing unconventional and low-margin oil resources; provide transport infrastructure for remote fields; reforming tax system to better suit the new environment. This way, crude production can be maintained above 500 mtoe in the forecast period and exports even surpass 2018 levels. In any case, however, the need for massive investments and tax incentives coupled with global movement away from fossil fuels means, that in the future oil will be becoming less and less profitable for the state budget, thus Russian government needs to redouble efforts on economic diversification and energy transition.

Man in the Context of Traditional Culture: Metaposition and Dialogue between Researchers of Different Sciences
Authors: Obukhov Aleksey S. , Ovchinnikova Yulia S. , Tkachenko Natalia V.
Published: September 2019

The article is devoted to the problem of organization of a productive dialogue between represen­tatives of different sciences during the comprehensive interdisciplinary research of man in the context of traditional culture. The prerequisites to the given problem statement have been formed during a long-term experience of joint field studies made by the authors in Russia (Adygea, Russian North, Bashkiria, Burya­tia, Kabardino-Balkaria, North Ossetia, Khakassia, Yakutia and other regions) and Mexico, as well as through the analysis of relevant results of academic and research work. As a solution of the given task, the authors develop the methodological construction “metaposition” that allows to approach to complexity and interdisciplinarity of research through the principle of dialogue in the common sociocultural field. Metaposition as a technology of organization of polyprofessional cooperation of different experts in a common research space is aimed at development of scientists’ skills of fi­xation, systematization and representation of the results of their work taking into account positions of their colleagues from other subject areas. Realization of this technology leads to creation of a metalanguage and to widening of researcher’s scientific culture (theoretical frames of each expert, style of their scientific reaso­ning and personal qualities). The development of metaposition as a stable system of cooperation between different positions of researchers suggests three interrelated stages: defining the research’s common field; revealing the borders of scientific positions; constructing the interpositional dialogue. Opportunities of application of the methodological construction “metaposition” at different stages of field research (before the field, at the field, after the field, during analysis of the field data) are concretized through a relevant algorithm and supported by examples from the field practice.
Jean-Honoré Fragonard’s Work and the Theatre Culture of the 18th Century
Authors: Agratina Elena E.
Published: September 2019

The article, for the first time, exami­nes the work of the master of the 18th century Jean-Honoré Fragonard (1732—1806) within the context of the theatre culture of that time. Being a student of François Boucher (1703—1770), who was working as a theater decorator for a long time, Fra­gonard from his youth had the opportunity to join the world of theater. The painter’s passion for the stage greatly influenced the thema­tic and figu­rative composition of his works. Early histo­rical pain­tings of Fragonard, such as “Jeroboam Sacrifi­cing to Idols” (1752, School of Fine Arts, Paris), were crea­ted under the influence of Baroque thea­ter and decorative art and opera productions. Undoubtedly, Fragonard’s familiarity with theatre was promoted by his long stay in Italy, where the famous families of theater decorators Bibiena and Galliari was wor­king at that time. The article pays special attention to the process of planning and execution of the painting “The High Priest Coresus Sacrificing Himself to Save Callirhoe” (1765, Louvre), made not without regard to the opera “Callirhoe”, popular in Paris in the 18th century. It was theater that inspired the master to create his famous costume series of “Fantasy Portraits”, one of which depicted Marie-Madeleine Guimard (1743—1816), who not only had posed for the artist, but also ordered him to design her own mansion conceived as a temple of Terpsichore, the Muse of dance. In addition, Fragonard was the author of several panoramic genre paintings conveying the atmosphere of the then popular street theater. Works of this brilliant master exem­plify the relationship of arts that determined the nature of the cultural environment of that era and requires constant attention from modern researchers.
Interface-rich Aqueous Systems for Sustainable Chemical Synthesis
Authors: Kaldre Dainis , Gallou Fabrice , Sparr Christof , Parmentier Michael
Published: September 2019

Mimicking an enzyme's exquisite activity and selectivity is a long-standing goal for sustainable chemical method development in aqueous media. The use of interface-rich aqueous systems, such as single-chain polymers, micelles and vesicle membranes recently emerged as strategy to emulate
the compartmentalization of natural systems. In aqueous solution, aggregates such as micelles or microemulsion droplets are formed, providing reaction environments different from bulk solutions that frequently improve selectivity and accelerate reaction rates for a wide array of chemical transformations.
We present here selected examples of interface-rich aqueous systems and discuss the advantages they offer for chemical synthesis. In particular metal-catalyzed cross-coupling reactions are highlighted and future challenges to perform reactions in interface-rich aqueous media are discussed.
Enzymatic PET Degradation

Published: September 2019

Plastic, in the form of packaging material, disposables, clothing and other articles with a short lifespan, has become an indispensable part of our everyday life. The increased production and use of plastic, however, accelerates the accumulation of plastic waste and poses an increasing
burden on the environment with negative effects on biodiversity and human health. PET, a common thermoplastic, is recycled in many countries via thermal, mechanical and chemical means. Recently, several enzymes have been identified capable of degrading this recalcitrant plastic, opening
possibilities for the biological recycling of the omnipresent material. In this review, we analyze the current knowledge of enzymatic PET degradation and discuss advances in improving the involved enzymes via protein engineering. Looking forward, the use of plastic degrading enzymes
may facilitate sustainable plastic waste management and become an important tool for the realization of a circular plastic economy.
Water in Hydration Shell of an Azide Ion: Structure and Dynamics of Solute-water Hydrogen Bonds and Vibrational Spectral Diffusion from First Principles Simulations At Supercritical Condition
Authors: Karmakar Anwesa
Published: September 2019

A series of ab initio MD simulations has been carried out for aqueous azide (N3-) ion solutions at three different densities and at supercritical condition (673 K) using Car-Parrinello molecular dynamics simulation. The time dependent trajectories at three different densities have been used to analyze the hydrogen bond dynamics, residence dynamics, dangling OD bond dynamics and spectral diffusion and underlying connections between them. The time dependent frequency of both the OD and NN stretching mode has been calculated using the time series analysis of the wavelet method. The population correlation function approach has been used to compute the hydrogen bond dynamics, dangling OD bond and residence dynamics of the Sc-water both inside and outside the solvation shell of the ion. The faster hydrogen bond dynamics has been observed in the vicinity of the azide ion, however the calculated OD stretching frequency is found to show red shift in the vicinity of the azide ion indicative to the formation of stronger ion-water hydrogen bond even at the supercritical condition. The overall hydrogen bond dynamics at the supercritical condition was faster with respect to the aqueous azide ion solutions at the ambient condition.
Vibrational Ultra Strong Coupling of Water and Ice
Authors: Hiura Hidefumi , Shalabney Atef , George Jino
Published: September 2019

Water is of vital importance for life and human activities on Earth—it exhibits unique properties due to its interlinked and multipoint hydrogen bonding network. Here, we experimentally show that water can undergo vibrational ultra strong coupling (V-USC) in both the liquid and solid forms when the OH stretching mode of water or ice is resonantly coupled with an optical mode of an infrared Fabry−Pérot cavity. The light-coupled H2O under V-USC reveals the largest Rabi splitting ever reported, reaching 22% and 26% of the vibrational energy for water and ice, respectively. We confirm that the extraordinarily large Rabi splitting stems from the densely packed minuscule molecular structures, large vibrational energies, and broad and intense absorptions due to intermolecular hydrogen bonding. These new findings offer a brand-new platform in polaritonic chemistry for controlling the properties of water with an ultra strong light-matter interaction.
Wetting Properties of the CO2–Water–Calcite System via Molecular Simulations: Shape and Size Effects
Authors: Silvestri Alessandro , Ataman Evren , Budi Akin , Stipp Susan , Gale Julian D , Raiteri Paolo
Published: September 2019

Assessment of the risks and environmental impacts of carbon geosequestration requires knowledge about the wetting behavior of mineral surfaces in the presence of CO2 and the pore fluids. In this context, the interfacial tension (IFT) between CO2 and the aqueous fluid and the contact angle, theta, with the pore mineral surfaces are the two key parameters that control the capillary pressure in the pores of the candidate host rock. Knowledge of these two parameters and their dependence on the local conditions of pressure, temperature and salinity is essential for the correct prediction of structural and residual trapping. We have performed classical molecular dynamics simulations to predict the CO2–water IFT and the CO2–water–calcite contact angle. The IFT results are consistent with previous simulations, where simple point charge water models have been shown to underestimate the water surface tension, thus affecting the simulated IFT values. When combined with the EPM2 CO2 model, the SPC/Fw water model indeed underestimates the IFT in the low pressure region at all temperatures studied. On the other hand, at high pressure and low temperature, the IFT is overestimated by ~5 mN/m. Literature data regarding the water contact angle on calcite are contradictory. Using our new set of force field parameters, we performed NVT simulations at 323 K and 20 MPa to calculate the contact angle of a water droplet on the calcite {10.4} surface in a CO2 atmosphere. We performed simulations for both spherical and cylindrical droplet configurations for different initial radii, to study the size dependence of the water contact angle on calcite in the presence of CO2. Our results suggest that the contact angle of a cylindrical water droplet on calcite {10.4}, in the presence of CO2, is independent of droplet size, for droplets with a radius of 50 Å or more. On the contrary, spherical droplets make a contact angle that is strongly influenced by their size. At the largest size explored in this study, both spherical and cylindrical droplets converge to the same contact angle, 38 degrees, indicating that calcite is strongly wetted by water.

Published: September 2019

The kinase PfCLK3 plays a critical role in the regulation of malarial parasite RNA splicing and is essential for the survival of blood stage Plasmodium falciparum. We recently validated PfCLK3 as a drug target in malaria that offers prophylactic, transmission blocking and curative potential. Herein we describe the synthesis of our initial hit TCMDC-135051 1and efforts to establish a SAR with a 7-azaindole-based series. A total of 14 analogues were assessed in a TR-FRET assay against the full recombinant protein kinase PfCLK3 and 10 were further assessed in parasites 3D7 (chloroquine sensitive) strains of P. falciparum. SAR relating to rings A and B was established. These data suggest that TCMDC-135051 1is a promising lead compound for the development of new antimalarials with a novel mechanism of action targeting PfCLK3.

Published: September 2019

The elderly population experience many health issues that range from emotional, psychological to physiological conditions. Previous studies reveal that chronic pain is among the major health issues affecting old people. The processes of managing chronic pain among the elderly have proven to be challenging practices since individuals exhibit different health complications in advanced age.   Saudi Arabia is among the countries that have made progressive improvements to the approaches employed to address chronic pain. Thus, exploring the status of elderly patients experiencing chronic pain in three major hospitals in Saudi Arabia is an educational strategy to understand the situation both in the middle east and the rest of the world. The notable chronic ailments associated with the elderly in Saudi Arabia include diabetes, back pain, and depression. Several studies have shown that the systems for treating older adults that suffer from chronic pain in Saudi Arabia are effective.

The prostate grows in two different ways-in one type of growth, cell multiply around the urethra and squeeze it whereas in the second type of growth is middle lobe prostate growth in which cell grow into the urethra and the bladder outlet area. This type of prostate growth typically requires surgery. The first line of care for treating BPH is often medication.2   Efficacy of Vasti therapy an Ayurvedic therapeutic procedure was studied in 75 patients of Benign Prostatic Hyperplasia (BPH). The treatment was given for 21 days, and then the effect was assessed clinically and objectively. Objective observations include determination of size (weight) of prostate and residual urine in the urinary bladder by ultrasonography, estimation of blood urea, serum creatinine and routine, microscopic and microbiological study of urine was also done.

Natureza humana e fundamento da ação moral em Kant
Authors: Perrucci Adamo
Published: September 2019

O conceito de natureza humana desempenha um papel crucial na empreitada kantiana de fundamentação da moral. A tematização da essência humana remete para a ambivalência do humano, por ele pertencer tanto à esfera fenomênica quanto à numênica. À luz deste pressuposto fundamental objetiva-se discutir a relação existente entre o fundamento objetivo do agir e o exercício da subjetividade, determinadora de normas e princípios morais. Focando a atenção sobre a Fundamentação da Metafísica dos Costumes e a Crítica da Razão Prática tentaremos conferir se é realmente compatível, na reflexão kantiana, a liberdade/autonomia do sujeito moral com a dimensão a priori do princípio incondicional da ação humana.

Authors: Netto Evania Alves , Bergsleithner Joara Martin
Published: September 2019

Este estudo tem como objetivo analisar um curso online de gramática de inglês como língua estrangeira (LE) a fim de investigar como é feita a instrução gramatical e como é elaborado o design pedagógico dos exercícios com as estruturas gramaticais (Netto, 2012). O estudo investigou um curso online de gramática em inglês com as seguintes perguntas de pesquisa: (a) Que foco é dado na apresentação do tópico gramatical: foco na forma, foco nas formas ou foco no significado? e (b) Que tipos de instrução são apresentados nas atividades? Os resultados mostraram que o curso analisado ministra a gramática de maneira tradicional, sem contextualização e com foco primordialmente nas formaS (Long, 1991). Os resultados também fornecem algumas contribuições na reelaboração do design do curso a partir da base originalmente criada, de modo que o curso possa espelhar melhor as pesquisas na área do ensino de línguas na modalidade online e que a instrução pudesse ser centrada na forma-ICF (Ellis, 2001). Por fim, são mostradas algumas limitações do estudo, sugestões para futuras pesquisas, assim como são sugeridas algumas implicações pedagógicas para serem trabalhadas em aulas de línguas mediadas por computador.

Crude oil is known to have an impact on people’s life of both producers and consumers of crude oil countries. A producer country’s socio-political impact will be different from a consumer country’s socio-political impact. This paper aims to show that crude oil price has a socio-political impact on global countries through descriptive analysis. The study found that there were similarities in the movement of crude oil price and change in GDP of both India and United States and further Russia and Venezuela have had crude oil impact on their respective GDP’s, which has made them take policy reforms. The paper identifies changes in the policy framework due to influence of crude oil price and eventual changes in existing socio-political environment. Taking oil producing countries such as Russia and Venezuela as examples, this paper suggests that policy reforms are the key to having a stable socio-political environment. Russia shows us that having a flexible monetary policy can keep the budget dependence on crude oil reduced in the short term. On the other hand, for oil consuming countries, having a stable supply and moving to new energy sources is the key to tackle the influence of crude oil price on the socio-political environment of global countries.
