Static behaviour of a two-tiered Dou-Gong system reinforced by super-elastic alloy
Authors: Xie Wenjun , Wang Tsung-Hsien , Chang Wen-Shao
Published: April 2019

The Dou-Gong system in Asian timber structures plays an important role in resisting seismic action. Traditional carpentry in Asia uses timber pegs to connect components, which enables relative movement between components and hence provides friction to dissipate energy in an earthquake. This method, however, has some shortcomings, such as inadequate stiffness to resist a large lateral force, and, therefore, the structures tend to exhibit permanent deformation after earthquakes. This study proposes a new technique by using super-elastic alloy bars to replace conventional wooden peg connections to enhance the seismic performance of the structures. Static pushover experiments were conducted on full-scale two-tiered Dou-Gong systems, and high-strength steel and conventional wooden pegs were used as benchmarks. The ultimate stiffness of the Dou-Gong system has shown an increase when both high-strength steel and super-elastic alloy bars were used, but only super-elastic alloy can provide a consistently high damping ratio. This technique also involves pre-strain of the super-elastic alloy, and the outcomes of this series of experiments have shown that pre-strain of the super-elastic alloy can significantly increase the damping ratio in the structure, and, hence, more energy is dissipated. The results of this paper can be used in projects of timber structures using the Dou-Gong system.
Large-scale triaxial compression tests of geocell-reinforced sand
Authors: Song F. , Liu H. , Yang B. , Zhao J.
Published: April 2019

A series of large-scale triaxial compression tests were performed on sandy soil confined by a circular geocell in this study. The effects of the relative density of the infill sand, the stiffness and strength of the geocell, and the aspect ratio (height-to-diameter ratio) of the specimen on the overall behavior of the geocell-soil composite were investigated. Furthermore, the measured confining pressure increment and apparent cohesion induced by the geocell membrane confinement were compared to those predicted by existing equations. The study results indicated that the end effects were very small in this experimental study. The effect of geocell stiffness on the stress-strain behavior of geocell-soil composites is closely related to the relative density of the soil. The measured confining pressure increments and the apparent cohesion are generally in good agreement with those predicted by Bathurst and Karpurapu's equations. The effect of the axial strain at failure on the apparent cohesion is discussed, and a method is proposed to determine the axial strain at failure for medium dense sand and dense infill sand on the basis of the hyperbolic nonlinear elastic model.

Authors: Balega A. , Vyzhva S. , Kurylo M.
Published: April 2019

The national experience of institutional support for the study and use of subsoil are defined. The subjects of interaction in the sphere of geological mining use are defined, the mechanism of interaction is shown. The institutional provision of the study and use of subsoil is divided into three blocks of influence: institutions of general competence, inter-sectoral institutions of special competence and sectoral institutions of special competence. The role of the State Service of Geology and Mineral Resources of Ukraine in the system of institutional support of geological study and use of subsoil is determined. The structure of the State Service of Geology and Mineral Resources of Ukraine was systematized and the basic functions and directions of activity are defined. It is revealed that state financing of development of mineral base of Ukraine takes place through the system of enterprises and organizations belonging to the State Service of Geology and Mineral Resources of Ukraine.

The structure and features of geological services in Germany, Poland and Australia were investigated. In the course of this analysis, a number of typical and a number of distinctive functions were identified for the geological services of the above mentioned countries. The State Service of Geology and Mineral Resources of Ukraine does not provide a number of key and progressive functions in the field of geological study and use of subsoil, such as: monitoring the state of the market of mineral resources, popularization of the mineral raw materials complex and enhancement of the investment attractiveness of the mineral base of Ukraine. It is concluded that for the introduction of foreign experience, changes should be made to the structure of the State Service of Geology and Mineral Resources of Ukraine. The study of the functional experience and the role of geological services in Australia and Germany testify to the effectiveness of regional geological services in the development of mineral base of these countries. Since the decentralization process in Ukraine has not been completed, experience in providing broad powers to local government bodies, a mineral base cannot be easy implemented.
Some challenges of treaty regulation of international relations in the field of environmental protection
Authors: Ilyinskaya O. I.
Published: April 2019

International agreements and treaties in the field of environmental protection concluded in the 19th — first half of the 20th century, were, as a rule, the result of forced compromises, they were intended to solve urgent problems that had appeared or, at least, drew attention to limited areas (for example, the threat to a certain species, pollution of a marine area). In such cases, a convention was adopted to protect an endangered species or to limit emissions into the sea. As a result of this fragmented approach to environmental protection, an impressive but very heterogeneous system of conventions has emerged. Understanding of the unity of ecosystems implemented in the development of principles enshrined in the Stockholm Declaration of 1972 and the Rio Declaration of 1992 took place largely due to the rapid progress of science and technology. As a result, there has been a transition from “spontaneous” formation of international environmental standards to their consolidation around special principles of international environmental law. Also, a notable feature of many international treaties in the field of environmental protection — their “framework” character — is further analyzed. The adoption of framework agreements leads to the formation of complex sets of conventional documents consisting of several different, but in a certain way related to each other agreements. Considering the question of the effectiveness of such a legal instrument as a framework agreement, the author concludes that the origins of the problem of insufficient effectiveness of agreements in the field of environmental protection lie in the foundations of the existing economic system.
Legal problems of using cloud services of foreign providers by Russian banks
Authors: Kanashevskiy V. A.
Published: April 2019

The paper examines the legal aspects of the use of cloud solutions by Russian banks of foreign providers. Despite the obvious advantages, there are many obstacles to such a use in the Russian legislation, including the lack of general regulation of cloud computing services, requirements for information security (licensing of encryption activities, certification of information systems), requirements of legislation on the localization of personal data databases, electronic databases of banks, etc. Based on the analysis of existing regulations, in particular the industry regulators, the author comes to the conclusion that foreign cloud service providers have the right to provide services to Russian financial institutions under certain conditions: cloud solutions should not include outsourcing of business functions entirely and should not involve the production of internal (domestic) money transfers (payments); foreign cloud provider has taken measures to protect the protected information; cross-border transfer of personal data and bank secrecy should be carried out in an impersonal form, etc.

Authors: Vorontcova Olga I. , Udochkina Larisa A. , Baranec Marina S. , Grechitaeva Marina V. , Goncharova Ludmila A.
Published: April 2019

Background. There is evidence for violation or a complete change in the arm swing cycle during walking in a number of pathologic conditions.
Aim. We assess the functional state of the shoulder and elbow joints in normal conditions and with joint hypermobility syndrome (JHS) using the kinematic instrumental method of analyzing gait.
Material and methods. We studied 27 adolescent girls 1215 years old with JHS and healthy subjects. A Vicon motion capture analysis system (Vicon, Oxford, Great Britain) was used to record biomechanical parameters.
Results. A decrease in limb movement amplitudes was noted in the shoulder joint around the frontal and sagittal axes in patients with JHS compared to the norm. During the arm swing cycle in the normal state, the shoulder is in a state of internal rotation, whereas in the girls with JHS, the shoulder is in a state of external rotation for most of the arm swing cycle. The elbow joint in the JHS subjects showed a significant increase in flexion angle of the forearm in the swing phase of 41.5 0.90 and a decrease in this angle in the stance phase. The JHS group also showed a decrease in power of the muscles acting on the shoulder joint.
Conclusions. A common sign of changes in the range of motion of the links of the upper limb in the shoulder and elbow joints in subjects with JHS was decreased amplitude of their flexion and decreased power of the joints. In the adolescents with JHS in the shoulder joint, a significant decrease in the internal rotation angles and reduction of the limb was found.

Authors: Lobachevskaya Tatiana V. , Talova Daria M. , Sogoyan Marina V. , Ovechkina Alla V.
Published: April 2019

Introduction. Since the end of the last century, dysfunction of the trace element composition of blood in various forms of scoliosis has been an urgent problem in several studies. Hidden deficiency of trace elements, associated with insufficient food consumption or low absorption in the body, can cause progressive bone deformities. In this context, special importance is attached to trace elements, such as copper, selenium, zinc, boron, manganese, and others. The study of the trace element concentrations in patients with congenital spinal deformities currently is an important and significant task.
Aim. We assess the trace element composition of whole blood in children with congenital deformities of the thoracic and lumbar vertebral columns.
Materials and methods. We analyzed the trace element status of blood in 108 patients (aged 216 years) with congenital deformities of the thoracic and lumbar spine (CSD). The congenital vertebral anomalies included disorders of formation, fusion, and/or segmentation of the vertebrae. The control group consisted of 35 healthy children of identical age. Blood ethylenediaminetetraacetic acid (EDTA) was examined using mass spectrometry with inductively coupled plasma (ICP-MS ThermoScientific, iCAP RQ).
Results and discussion. The content of 33 essential and conditionally essential trace elements in the whole blood of patients with CSD was determined. In 37% of patients the zinc, copper, selenium, and chromium levels were decreased compared with the controls. In 7% and 89% of patients the selenium and of chromium levels, respectively, were especially low, below the sensitivity of the device.
Conclusion. The statistically significantly low content of zinc, copper, selenium, and chromium in the whole blood of patients with CSD may have a role in the pathogenesis of the disorders. Further investigations are needed to evaluate their importance as a marker of disease progression.

Published: April 2019

Introduction. The task of preserving the psychological health of children and adolescents is recognized as most important in the complex conditions of the modern world. Interdisciplinary research addresses the psychological aspects of mental health. For psychological health, understanding the highest level of mental health is an integral characteristic of the well-being of the individual, and the prerequisites for the development of personal maturity. Among the adverse factors in relation to mental and psychological health is what is known as somatic suffering, which occurs in orthopedic diseases. Cognitive, emotional, and behavioral responses to orthopedic disease, eliminating maladaptive manifestations in difficult life situations due to the disease, can be important indicators of psychological health of adolescents.
Aim. We identify specific indicators of psychological health in adolescents with various orthopedic diseases.
Materials and methods. The study involved 90 adolescents: 60 aged 1217 years with orthopedic diseases (30 with articular juvenile chronic arthritis and 30 with long-term consequences of mechanical trauma of the upper and lower limbs, resulting from an accident due to negligence) and a control group consisting of healthy adolescents of the same age. The characteristics of the self-esteem personality component (satisfaction with various aspects of their own lives) in adolescents with orthopedic diseases and their healthy peers were considered traditional indicators of psychological health. We used PiersHarris scale modified by V.I. Gordeev Y.S. Aleksandrovich and test of attitude to disease.
Results. In adolescents with various forms of orthopedic disorders, the formation of stable variants of the attitude to the disease with a violation of adaptation of inter- and intrapsychic types is accompanied by the experience of discomfort, difficulties of self-regulation during treatment, and signs of a negative attitude. Formation of stable variants of emotional, cognitive, and behavioral responses without expressed disorders of mental and social adaptation is accompanied by a feeling of comfort and self-satisfaction. The prevailing reaction at harmonic, allopathic, and anosognosic types of mogutt act as a sanogenic effect. Emerging resistant variants of the attitude to the disease with a violation of adaptation of inter- and intrapsychic types can represent risk factors for breach of psychological health in adolescents with orthopedic diseases.

Authors: Fedorova Mariya V.
Published: April 2019

Abstract. Assessment of public efficiency of rapid urban transport development strategy is the final stage in the formation of a strategy for the development of rapid transport.

The rapid urban transport development strategy is distinguished by the following main characteristics:

significant initial investment, which in some cases is considered as an objective obstacle to adoption and implementation of the strategy;

long timeframes for implementation of the strategy;

timing of the achievement of the goals;

use of financial resources.

These characteristics enhance the current cost of the project. The process of measuring the results a new transport project implementation is complicated, because a significant part of the results is of external character and is not subject to cost measuring.

The peculiarities listed above prove the relevance of determination of public efficiency rapid urban transport development strategy. Considering the specifics of the object of the research, the comparison of costs and results of innovative transport product implementation should be carried out within assessment of its public efficiency.

The aim of this work is to develop a system of indicators for assessment of public efficiency of rapid urban transport development strategy; study of existing public efficiency assessment methods, search for their advantages and disadvantages, and research into maglev technology advantages.

The system of indicators proposed to assess public efficiency of rapid urban transport development strategy, considers all advantages of maglev technology and prioritises it in selecting rapid urban transport.

Authors: Kelkar Prasad A. , Hirekerur Jyoti V.
Published: April 2019

Background: Ossicular discontinuity can occur as a result of erosion by chronic otitis media or due to trauma. Reconstruction of the ossicular chain aims to surgically optimize the middle ear transformer mechanism. The goal of this study was to devise a protocol to manage the ossicular discontinuity, provide good hearing to the patients and to demonstrate that use of ossicle for ossicular reconstruction is a safe, physiological, practical, successful and cost effective method.

Methods: The present study is retrospective study of 50 patients who underwent ossiculoplasty in our institute over the period of 2 years. Most patients presented to us with a history of chronic intermittent ear discharge and decreased hearing. Detailed clinical examination included general examination and local examination of ear, nose and throat. Examination of ear included otoscopy, tuning fork tests, and examination under microscope.  

Results: The average pre-operative air-bone gap in patients with ossicular disruption was 34.95 dB and after ossiculoplasty was 12.93 dB. The mean air-bone closure after surgery was 27.88 dB. In most cases the post-operative air bone closure was within the range of 20 dB. The hearing results in ossiculoplasty are dependent on various factors but middle ear status in one of the most important factor in deciding the final outcome.

Conclusions: The ossiculoplasty using autograft has stood the test of time and the results are superior to that of prosthesis. They have less rate of complications, are economic and easily available. The expertise to sculpt the ossicle can be easily developed with practice.

Published: April 2019

O estudo tem como objetivo relacionar os investimentos em Pesquisa e Desenvolvimento com o desempenho organizacional de empresas participantes do bloco econômico BRICS. Trata-se de uma pesquisa descritiva, com abordagem quantitativa, realizada por meio de análise documental com dados coletados através da base de dados Thomson®, abrangendo uma amostra de 563 empresas do Brasil, China, Índia, Rússia e África do Sul (BRICS). Através da realização da análise dos dados em painel, concluiu-se que os investimentos em P&D relacionam-se significativamente com o desempenho organizacional e que os investimentos se revertem em lucros após dois anos do valor investido em P&D. Ainda, constatou-se que o indicador Liquidez influencia diretamente o ROA, pois empresas com alta liquidez deixam de investir em novos produtos, reduzindo, desta forma, a lucratividade futura da empresa.
Sentidos produzidos por professoras alfabetizadoras sobre a aprendizagem do ensino da leitura no contexto do PNAIC
Authors: Gonçalves Fabíola Mônica da Silva , Ferreira Sandra Patrícia Ataíde
Published: April 2019

Pensa-se a leitura como uma prática constituída das dimensões social, cultural e histórica, que remete à produção de sentidos, a práticas variadas de leituras e à subjetividade do leitor (DIONÍSIO, 2005; OLIVEIRA; FONSECA, 2016). Aliando-se também à perspectiva sócio-histórica em psicologia, assume-se que a subjetividade do leitor é constituída na relação dialética sujeito-realidade social, produzida no processo histórico de constituição da vida social (BOCK; AGUIAR, 2016). Entende-se, então, que em um contexto em que ocorre a formação de alfabetizadores no território brasileiro mediada pelo Pacto Nacional pela Alfabetização na Idade Certa (PNAIC), faz-se necessário apreender a significação dos professores sobre a formação no processo de ensino da leitura, concebido como um dos eixos que compõe o processo de alfabetização. Assim, tem-se como objetivo geral apreender os sentidos produzidos por professores sobre a formação para o ensino e aprendizagem da leitura na escola básica no contexto de formação profissional promovido pelo PNAIC. Como objetivos específicos pretendem-se: (i) analisar como os professores significam os processos de aprendizagem e desenvolvimento que fundamentam o PNAIC e que engendram a sua formação como sujeito-leitor; (ii) entender como esses profissionais significam as atividades de leitura constituídas no contexto da escola e na sala de aula com o advento da formação promovida pelo PNAIC; (iii) interpretar como os professores pensam recriar na realidade escolar a proposta de ensino de leitura promovido pelo PNAIC. Assim, foi realizado um estudo tendo como delineamento de pesquisa o Estudo de Caso Múltiplos (YIN, 2001), no qual foi utilizada a entrevista semiestruturada com duas professoras alfabetizadoras e, para a análise, foi adotada a perspectiva dos núcleos de significação proposta por Aguiar e Ozella (2006, 2013). Em linhas gerais, evidenciaram-se os avanços e os pontos que necessitam de reformulações com vistas a construção do sujeito-leitor constituintes da realidade educacional do processo de alfabetização.

The aim of the study was an approbation of molecular-genetic methods for an analysis of contents of fish stomachs of Abyssocottus korotneffi Berg, 1906, as an example.

Methods. Sampling carried out at the board of the research vessel «G.Yu. Vereshchagin» in August 2017 in the northern basin of Lake Baikal. To study a fish feeding, testing of a DNA extraction methods and PCR conditions was performed. A fragments of the CO1 gene were amplified from total DNA isolated from the contents of the fish stomachs. The composition of food was studied based on the analysis of nucleotide sequences cloned into the plasmid pJET vector.

Results. One species of amphipods closest to Odontogammarus calculator Dybowsky, 1874 was detected in fish food. In addition, sequences of cottoid fish were found in the studied samples. To date, information about a presence of fish in the food spectrum of this species was absent.

Conclusions. The main problem of using molecular-genetic methods in studies of fish food spectrum is not enough number of data of voucher sequences of the CO1 gene of Baikal organisms in the genetic databases. Despite on advantages of analysis of the CO1 gene in studies of fish food feeding, this approach does not allow to distinguish between organisms of the same species.
GEOECOLOGICAL DIAGNOSTICS OF THE REGIONS IN THE CENTRALBLACK SOIL REGION
Authors: Kurolap S. A. , Yakovenko N. V. , Fedotov V. I. , Mikhno V. B. , Kostyleva L. N.
Published: April 2019

Aim.The aim is geoecological diagnostics of regions of the Central Black Soil Region on the basis of which the areas with different degree of tension of a technogenic and medicoecological situation have been revealed. Material and methods of research. System, comparative-geographical, geoinformation, historical, statistical methods of research, as well as software packages MS Excel and Statistica have been used. The database has been formed in retrospect for the period 2006-2015. About 50 public health criteria and about 200 potential risk factors have been analyzed. 9 key (indicator) criteria have been selected.

Results.The authors propose an algorithm to perform geoecological diagnostics of the large region. The correlations between integral estimation criteria of levels of technogenic loadings and parameters of public health have been calculated. The positive correlations of weak and medium degree indicate the presence of stable trends: the increase in the levels of technogenic loads on the environment of the regions is an unfavorable "response" on the part of the population (the growth of environmentally caused pathology and, first of all, malignant neoplasms, as well as congenital anomalies in children). It is established that among the regions of the Central Black Soil Region this pattern is more pronounced for the area of the Belgorod region, where the environmental situation is much more contrasting, and the level of technogenic impact in the urban agglomeration zone is higher than, for example, in the Voronezh region.

Conclusion.In this scientific paper, the authors have solved the actual practice-oriented problem in the field of geoecological researches, namely, they have developed the method of geoecodiagnostics of a large region, which allows to quickly and reliably determine the degree of technogenic load on the area. The analysis of the obtained data allowed us to reveal the regularities of the formation of the geoecological situation in the area of the Central Black Soil Region, to formulate the main directions of environmental policy and to predict the dynamics of the geoecological situation development.

Aim.To identify the degree of influence of the morphological heterogeneity of the territory on the ecological state of the agricultural landscape.

MethodsThe study was conducted on an area of 608.5 hectares and a horizontal dissection factor of 8.36 km/km2. For the observations, distributed test pads measuring 10 m2 were used. On each type of facies, test sites were laid on arable land in triplicate. We used standard research methods using GIS. Existing thematic terrain maps were digitized and a digital elevation model based on a topographic survey of the terrain was created. Calculations and visualization of data are made using and based on the ArcGIS and Microsoft Excel software.

Results.The degree of influence of the types of facies of the landscape area on individual criteria and indicators of arable land productivity (microclimatic indicators, water properties of the soil, elements of fertility) has been established. Spatial ecologically justified differentiation of types of tracts into facies types has been carried out.

Main conclusions.The slopes of the northern exposure (I-IVn) have the highest ecological stability. They lead in the content of productive moisture, mobile phosphorus and potassium. The facies of the slopes of the southern exposure (I-IVs) lead by insolation, the content of humus and nitrate nitrogen. The content of heavy metals in the soils and wheat yield is higher on the southern slopes and second-order watersheds (IVn). The maximum productivity of 2.9 t/ha was obtained on the watershed type of facies (V). A close relationship was established (r = -0.72) between productivity and pH of soil, medium – with mobile forms of phosphorus (r = 0.59) and potassium (r = 0.84).
Uwaga na twórczość! Poznawcze aspekty kreatywności
Authors: Piotrowski Krzysztof T.
Published: April 2019

Głównym problemem badawczym jest różnicowanie stanu uwagi w czasie wykonywania zadań konwergencyjnych i dywergencyjnych. Zadania dywergencyjne wiązane są z procesami twórczymi. Zadania te wymagają różnorodnych i często nowych rozwiązań. Niezbędne jest wówczas aktywowanie w pamięci roboczej informacji słabo połączonych z siecią pamięci długotrwałej. Kluczowym procesem w aktywowaniu informacji w pamięci jest uwaga. Postawiona została hipoteza mówiąca, że zadania dywergencyjne są wykonywane przy większej ekstensyfikacji uwagi niż zadania konwergencyjne. Procedura badawcza wykorzystana w przeprowadzonym eksperymencie opierała się na jednoczesnym wykonywaniu zadania konwergencyjnego (odtwarzania zapamiętanej melodii) lub dywergencyjnego (improwizacja w oparciu o zapamiętaną melodię), przy jednoczesnym rozwiązywaniu testu mierzącego ekstensywność uwagi. Uzyskane wyniki wspierają postawioną hipotezę. Procesy twórcze zależą od stanu uwagi i jej aktywnego działania.

Dynamics between spirituality, leadership and life goals: A life narrative grounded theory study
Authors: Dames Gordon E.
Published: April 2019

In this article the relation between school leadership, spirituality and ultimate life goals is considered. The objective of the study is to explore how leadership and spirituality are related and informed by ultimate life goals in schools. Spirituality is defined as a way of life of growing into human fullness that is grounded in a moral universe. Ultimate life goals represent ultimate values in the lives of leaders and their deepest motivation for decisions and actions. Ultimate life goals originate from our contingent nature – as we move or change, we are constantly in need of a grounding/foundation. It gives direction and meaning in change and form through spiritual transformation. The life narrative research methodology was applied to explore the ultimate life goals and spiritual transformation in the life narratives of seven school principals in Roman Catholic private schools in Gauteng and two public schools in the Western Cape. Opsomming Hierdie artikel fokus op die verband tussen skoolleierskap, spiritualiteit en lewenseinddoelwitte. Dit is ’n verkennende studie wat daarop toegespits is om te bepaal hoe leierskap en spiritualiteit met mekaar verband hou en deur lewenseinddoelwitte in skole beïnvloed word. Spiritualiteit word omskryf as ’n lewenswyse om tot menslike volheid, gefundeer in ’n morele universum, te groei. Lewenseinddoelwitte verteenwoordig eindwaardes in die lewens van leiers sowel as hulle diepste motivering vir besluite en aksies. Lewenseinddoelwitte het hulle oorsprong in ons veranderlike natuur – soos ons beweeg of verander, het ons ’n konstante behoefte aan ’n grondslag/fondasie. Dit verskaf rigting en betekenis in verandering en vorm deur spirituele transformasie. Die navorsingsmetodologie van lewensnarratiewe is toegepas om die lewenseinddoelwitte en spirituele transformasie in die lewensnarratiewe van sewe skoolhoofde van Rooms Katolieke private skole in Gauteng en twee publieke skole in die Wes-Kaap te verken.
Bovinocultura de corte e SAN: percepção de sustentabilidade de agentes da cadeia

Published: April 2019

A bovinocultura de corte é uma das principais atividades do agronegócio brasileiro e o consumo de carne bovina tem grande relevância para a garantia da segurança alimentar. No entanto, a baixa produtividade da maioria dos sistemas produtivos associa a atividade à importantes impactos ambientais e sociais – o que, por consequência, também desperta questionamentos acerca da segurança alimentar. Com base neste contexto e no quadro conceitual da Nova Economia Institucional, este estudo teve como objetivo identificar a percepção de agentes da cadeia da carne bovina em relação aos desafios da atividade e da sustentabilidade da produção. Foram realizadas 15 entrevistas não-estruturadas com agentes do setor. Os resultados apontam que o aumento de produtividade é percebido pelos entrevistados como o maior e mais imediato desafio da cadeia. Ainda que o uso de tecnologias venha crescendo, e a pecuária esteja se modernizando, a falta de visão de longo prazo, aliado ao perfil tradicional do pecuarista, aversão a risco e grande cautela em realizar investimentos foram pontos enfatizados. Sistemas de integração lavoura-pecuária ou lavoura-pecuária-floresta foram chamados de “tendência” no que se refere à incorporação de sustentabilidade na produção. Entretanto, os resultados evidenciam que a percepção da importância da sustentabilidade ambiental é secundária, a medida em que os esforços estão direcionados para a sustentabilidade econômica da produção. Ainda assim, as sinergias produtivas dos sistemas de integração podem ser “portas de entrada” para o debate da sustentabilidade em suas múltiplas dimensões.
História da educação Matemática na Revista do Ensino de Minas Gerais (1925-1971)
Authors: Britto Flávia Aparecida , Gomes Maria Laura Magalhães
Published: April 2019

Neste artigo, discutimos aspectos teórico-metodológicos do uso de periódicos educacionais como fonte de pesquisa e focalizamos uma investigação sobre a matemática e o seu ensino na Revista do Ensino de Minas Gerais (RE) - impresso oficial de extrema importância para a história da educação mineira que circulou de 1925 a 1971. Tal investigação tem como corpus textos publicados na RE até 1940 que contêm referências à matemática ou a seu ensino. Ao levantarmos as características gerais desse corpus, constatamos que é variado o grupo formado por seus autores e coautores, que inclui personalidades do cenário político-pedagógico da época. Notamos, ainda, que o tipo mais frequente de texto é o relato de experiência/ observação/ pesquisa/ estudo e que foi muito expressiva na RE a presença dos seguintes temas: a matemática nas escolas após as reformas de 1927; concepções/ visões/ valores relacionados à matemática e/ou a seu ensino; orientações/sugestões para a abordagem de conteúdos matemáticos.
Livros didáticos e outros materiais escritos no Colégio Técnico da UFMG (1969-1997)
Authors: Melillo Kelly Maria de C. Fornero A. L. , Gomes Maria Laura Magalhães
Published: April 2019

Este artigo aborda o uso de livros didáticos e outros materiais escritos nas práticas dos professores de Matemática do Colégio Técnico da Universidade Federal de Minas Gerais no período 1969-1997. O trabalho resulta de uma pesquisa fundamentada na metodologia da História Oral, com a realização de 16 entrevistas com antigos professores e alunos da escola. Os depoimentos dos professores minimizaram o papel dos livros em suas práticas, acentuando a sua própria produção de materiais escritos, com destaque para estudos dirigidos e instruções programadas para as aulas. Os testemunhos dos alunos se referiram à pouca frequência de aulas expositivas decorrente do uso desses materiais e em geral não enfatizaram o uso de livros. Entretanto, a análise das narrativas revelou que os livros didáticos estiveram muito presentes nas práticas desenvolvidas na escola, por serem essenciais à preparação e à realização dos estudos dirigidos.
Três movimentos metodológicos para o estudo da Biblioteca Pessoal Alda Lodi
Authors: Amorim Brian Diniz , Gomes Maria Laura Magalhães
Published: April 2019

O artigo apresenta três movimentos metodológicos empreendidos em uma pesquisa realizada tomando como fonte e objeto a biblioteca da professora Alda Lodi. O texto é centrado na apresentação e discussão das escolhas metodológicas  realizadas nos três movimentos empreendidos: o primeiro, a constituição do corpus de pesquisa através de uma catalogação dos livros da biblioteca; o segundo, uma investigação dos autores mais citados nos livros da biblioteca mediante o mapeamento das referências bibliográficas; o terceiro, a escolha de dois livros para uma análise mais aprofundada e a investigação das marcas de leitor presentes nesses livros. Destacam-se as implicações das escolhas para a pesquisa, assim como defende-se a adoção de procedimentos metodológicos adequados e posteriores ao conhecimento dos objetos de pesquisa. Por fim, ressalta-se a possibilidade do uso das marcas de leitor na compreensão dos usos do texto pelo professor-leitor.
