Authors: Glotov A V , Fedorova T N , Goltyapin V V , Akhmedov V A
Published: February 2018

Aim. By using mathematical modeling, to evaluate the impact of upper respiratory tract diseases, retro- and micrognathia, and body mass index (BMI) on nocturnal pulse oximetry indicators (oxygen saturation level and oxygen desaturation index) in outpatients examined for suspected obstructive sleep apnea syndrome (OSAS). Subjects and methods. The study enrolled 260 subjects with a mean age of 47.8±12.0 years. All the examinees underwent outpatient pulse oximetry screening during nocturnal sleep because of suspected OSAS. Multislice spiral computed tomography was carried out to assess the paranasal sinuses and nasal septum. BMI was calculated. Variance factor analysis using an original programming application intended to create binary and ternary dispersion complexes was employed as a main mathematical tool. Results. There were statistically significantly sets of risk factors for OSAS: nasal septum deviation + increased BMI + male gender = 68.66%; chronic allergic rhinitis + increased BMI + male gender = 63.09%; retromicrognathia + increased BMI + male ganger = 59.48%; and chronic tonsillitis + increased BMI + male gander = 60.88%. Higher BMI and male gender are a most statistically significant set of risk factors. Conclusion. Pulse oximetry screening during nocturnal sleep in snoring patients with suspected OSAS in combination with an assessment of age, sex, BMI, ENT comorbidity, retro- and micrognathia can predict the severity of the disease and serve as a basis for elaborating an OSAS screening program.

Authors: Fomin V V , Svistunov A A , Napalkov D A , Sokolova A A , Skripka A I , Morina N A , Fedorova E A
Published: February 2018

The paper gives an overview of the European Society of Cardiology (ESC) guidelines updated in 2017. The revised and amended guidelines for areas, such as dual antiplatelet therapy (DAT), treatment of patients with ST-segment elevation myocardial infarction (STEMI), and management of patients with valvular heart disease and peripheral artery disease, were presented in late summer of this year. The authors of this paper present an independent analysis and discussion of new data on the key issues of diagnosis and treatment in patients in the above areas. The recommendations on DAT pay special attention to the timing of the therapy and to the choice of its drugs. The updated data on the treatment of patients with STEMI accurately determine the time to percutaneous coronary interventions, approaches to revascularization; the updates touch upon fibrinolytic therapy and new approaches to lipid-lowering therapy too. Recommendations for the management of patients with peripheral artery atherosclerosis propose for the first time a section devoted to the choice of antiplatelet therapy (an antiaggregant and/or an anticoagulant) depending on the clinical situation.

Published: February 2018

Aim. To investigate the association of the polymorphic marker -3279 C>A of the FOXP3 gene with the risk of pulmonary sarcoidosis (PS) and to estimate the transcription level of this gene in the carriers of different genotypes of this polymorphic marker. Subjects and methods. The investigation included 99 patients of Russian ethnicity (mean age, 45.41±1.31 years) living in the Republic of Karelia, who were diagnosed with persistent PS, and 116 healthy donors (mean age, 42.06±1.30 years) in the control group. The alleles and genotypes of the polymorphic marker -3279 C>A of the FOXP3 gene were identified using polymerase chain reaction (PCR)-restriction fragment length polymorphism. The number of transcripts of the studied gene in the peripheral blood leukocytes of healthy donors and PS patients was determined with real-time PCR. Results. The control group and the PS patient one had no statistically significant differences in the distribution of the frequencies of alleles and genotypes by the polymorphic marker –308G>A of the FOXP3 gene (p > 0.05). The number of FOXP3 gene transcripts was not statistically significantly different in the peripheral blood leukocytes of patients with PS and control individuals. No statistically significant differences were observed in the mRNA expression levels in the above-mentioned gene in the carriers of different genotypes by the polymorphic marker -3279 C>A of the FOXP3 gene in all examined groups. Conclusion. The polymorphic marker -3279 C>A of the FOXP3 gene is unassociated with the risk of PS.

Published: February 2018

Aim. To evaluate the efficacy of pregabalin in the therapy of chronic pain in patients with knee osteoarthritis (KOA). Subjects and methods. The study enrolled 60 patients with KOA and neuropathic pain component (NPC) (Douleur Neuropathique en 4 questions (DN4) questionnaire scores, >4) who were randomized into two groups to receive aceclofenac or aceclofenac + pregabalin for 5 weeks. All the patients underwent clinical and neurological examinations, assessment of the functional WOMAC index, pain intensity at rest and during movement, and diagnosis of neuropathic pain (NP) (DN4 and Pain DETECT questionnaires). Results. Both groups were observed to have positive changes in the studied parameters; however, combination therapy using an anticonvulsant drug (pregabalin) showed a more pronounced positive effect against not only NPC, but also the functional activity (WOMAC) and severity of pain (visual analogue scale). Conclusion. Combination therapy using pregabalin in KOA patients having the signs of NP is more effective than monotherapy with nonsteroidal anti-inflammatory drugs (aceclofenac).

Aim. To assess the results of following up patients with chronic myeloid leukemia (CML) and a deep molecular response (MR) without tyrosine kinase inhibitor (TKI) therapy. Subjects and methods. The reasons for TKI discontinuation in 70 patients with CML and a deep MR of more than 1 year’s duration were adverse events, pregnancy, and patients’ decision. Information was collected retrospectively and prospectively in 2008-2016. Results. The median follow-up after TKI therapy discontinuation was 23 months (2 to 100 months). At 6, 12 and 24 months after TKI therapy discontinuation, the cumulative incidence of major MR (MMR) loss was 28, 41 and 48%, respectively; the survival rates without TKI therapy were 69, 50, and 39%, respectively. MMR loss was noted in 28 (88%) patients at 12 months; it was not seen without TKI therapy at 2-year follow-up. Deaths due to CML progression were absent. The Sokal risk group was a reliable factor influencing MMR loss (p ≤ 0.05). The cumulative recovery rate for deep MR after resumption of TKI use was 73 and 100% at 12 and 24 months, respectively, with a median follow-up of 24 months (1 to 116 months). Deep MR recovered at a later time when the therapy was resumed more than 30 days after MMR loss. Conclusion. Safe follow-up is possible in about 50% of the patients with CML and stable deep MRs without TKI therapy. The introduction of this approach into clinical practice requires regular molecular genetic monitoring and organizational activities. Biological factors in maintaining remission after TKI discontinuation need to be separately studied.
Decarbonisation and the transport sector: A socio-economic analysis of transport sector futures in South Africa
Authors: Caetano Tara Helena , Merven Bruno , Hartley Faaiqa , Ahjum Fadiel
Published: February 2018

Globally, governments are investigating transport solutions that not only reduce their national emissions but also decrease their reliance on energy imports and increase clean air in cities and towns. A transition in the transport sector is seemingly inevitable considering these priorities. This study outlines some key socio-economic implications of a transition in South Africa’s transport system, building on work previously done. The focus was on a rapid decarbonisation of the South African economy and the potential impacts of implementing efficiency improvements in the transport sector, including mode-switching. The overall finding was that a more ambitious decarbonisation target would have marginal impact on the economy relative to South Africa’s nationally-determined contribution. It was further found that the implementation of efficiency improvements and changes in behaviour (decreased mileage, increased occupancy, increased rail use and increased use of public transport) could significantly reduce the burden on the economy of a higher GHG emission reduction target.

COMPOSITE METHOD: MEGA-OBJECT MODEL UPDATING, ITS VALUE AND PROCEDURES
Authors: MALAKHOV Sergey A.
Published: February 2018

The paper discusses the concept of mega-object, which is a review of the relationship between the object and the environment from the perspective of enhancing specifi c individual actions of the designer. The central aspect of this conception is an individually executed model of an urban landscape fragment, which is one of the key subsystems of the environment. The fi rst thing that this model does is to achieve the plastic integrity of the form of an environment fragment. As a result, from the perspective of this concept, some single object cannot be fully eff ective without being an integral part of this whole. All modeling procedures developed in the composite method introduced by the author are subordinated to the idea of assembling or cutt ing the body of mega-object. The composite method here serves as an organic link to art, fi rst of all, to plastic art. The article emphasizes the importance of Frank Lloyd Wright's activities as the founder of an organic architecture, gives a classifi cation of mega-objects and describes how they are dependent on the so-called "Size scale" of the composite method design.

Authors: REPINA Evgenia A. , ROMANOVA Daria N.
Published: February 2018

The paper demonstrates values of an anonymous language and its potential for design practice. It att racts att ention to the problem of unprofessional architecture which is underestimated in professional practice. The thing is that squatt er development is usually seen as a product of poor architecture and is widely destroyed and replaced by typical unifi ed objects. The question of the legitimacy of such project invasion is raised in the paper. It puts forward a methodology for working with anonymous languages and demonstrates how to do taking the so-called "Red houses" (districts within Cheremshanskaya - Nagarnaya - Voronezhskaya - Kalinin streets and Rotorniy alley) as an example. The paper covers issues which were faced during the work. It takes three projects - that is "Municipal Design", "Public design" and "Custom design" - as examples and explores strategies of the design "intervention" of a professional architect and ways of dialogue with the environment on the language level.

Published: February 2018

Rabindranath Tagore (1861-1941), the famous poet and writer, is also regarded as a pioneer in rural development programmes and library movement in India. Aiming to make villagers self-reliant as well as self-dependent to make efficient use of resources for the fullest development of their physical, social, economic and intellectual potential and abilities, and get them acquainted with the cultural tradition of their own, Rabindranath initiated rural reconstruction programme at Sriniketan in the year 1922. To eradicate illiteracy in the villages around Sriniketan, he emphasized on collection and dissemination of information through the introduction of “Chalantika” (Mobile Library) services. This service continues through 38 village libraries (presently 34 are functioning) under the control of the Department of Lifelong Learning & Extension (formerly Rural Extension Centre) of Visva-Bharati with the financial assistance of Raja Rammohun Roy Library Foundation (RRRLF). This paper gives an overview of the rural libraries year-wise, number of Gram Panchayats served. Also discusses the growth of collection, use of books by readers, provision fund based on the five years Annual Report (2009-10 to 2013-14).

Published: February 2018

Social science research institutions play a vital role in society by way of creating, formulating public policies. This study focuses on social scientists’ approach to open access initiatives in India. A structured questionnaire was distributed among 288 faculty members of ICSSR institutes located all over India; 166 (58%) responses were received. The study findings show that, 67% of the respondents are aware of open access resources available in social science research arena, but are not very keen on publishing their research work in open access journals. Over 55% of the respondents have responded positively to citation of open access resources in their research publications. Visibility and free access are found to be the major advantages associated with open access journals, while expensive author publishing charge is the foremost hurdle to publishing articles in open access journals. Finally, the study concludes with the suggestion that OA publishers need to be more vibrant about maintaining the quality of research articles in addition to enlightening on the role of librarians in promoting the use of open access resources.
Informetric Studies on Physics Theses of Indian Institute of Science. By K.G. Sudhier
Authors: Harinarayana N.S.
Published: February 2018

The abundance of information poses a problem of a different kind just as lack of information does. Comprehending information and filtering it for consumption and decision-making are the major challenges faced by the modern society. Quantitative measurement techniques have been developed and used for the analysis of production and use of information. These techniques are in vogue for a few decades now, and these techniques form the basis for ‘bibliometrics’, ‘informetrics’, ‘scientometrics’, ‘webometrics’ etc. Altmetrics is the new research area added to this group. Purists do make a distinction in the scope and application of these fields of study, although from a student perspective they are overlapping disciplines. It may be mentioned that Indian literature on the subject refers to S.R. Ranganathan who introduced the term ‘librametry’ even before terms such as bibliometrics, informetrics, etc. came into vogue (Sen, 2015)

Además, se destacan dos casos de la relación conflicto armado y pobreza en el departamento de Antioquia (Oriente y Urabá), con dinámicas y resultados diferentes en cuanto al conflicto armado y a la pobreza. En las consideraciones finales se entregan rutas de análisis para comprender mejor el fenómeno de la pobreza en lugares afectados por el conflicto armado.
Renta negativa y decrecimiento económico
Authors: Cante Maldonado Freddy Eduardo
Published: February 2018

El objetivo del autor en este texto es la defensa de la siguiente hipótesis de trabajo: el creciente uso, alteración y extracción de recursos naturales, y la especulación monetaria, generan diversas rentas pero implican substracción de recursos no renovables y, además, generan una magnificada y acelerada degradación de la naturaleza, y producen costes sociales,  por lo que la rentas deberían ser negativas. La metodología empleada consiste en exponer una lectura crítica del concepto convencional de renta y, con base en teorías económicas heterodoxas y no convencionales, y alguna evidencia empírica tomada de fuentes secundarias, hallar un resultado teórico, el cual consiste en la propuesta de renta negativa. Concretamente se discuten las rentas de combustibles fósiles, del oro, y del dinero. Al final se muestran algunas pautas de cómo funcionaría la renta negativa. La principal implicación de este estudio es que la renta negativa conduce a una política económica orientada hacia el decrecimiento.
Análisis cristalográfico, morfológico, eléctrico, óptico y magnético del nuevo material Dy2BiFeO6
Authors: Roa-Rojas Jairo
Published: February 2018

En este trabajo reportamos el análisis estructural, morfología superficial, ordenamiento magnético, respuesta dieléctrica y característica óptica de la nueva perovskita compleja Dy2BiFeO6. Las muestras fueron producidas mediante reacción de estado sólido. El análisis cristalográfico fue realizado a través de refinamiento Rietveld de los patrones experimentales de rayos X. Los resultados muestran que este material cristaliza en una perovskita ortorrómbica correspondiente al grupo espacial Pnma (#62). Por medio del ajuste de Curie-Weiss a la respuesta de la susceptibilidad magnética en función de la temperatura se estableció que el ordenamiento magnético se relaciona con una transición paramagnético-antiferromagnético con una temperatura de Weiss θ=-18,5 K, la cual es acorde con el comportamiento del inverso de la susceptibilidad en función de la temperatura, y una temperatura de Néel TN=50,8 K. La constante de Curie permitió determinar un momento magnético efectivo de 15,7 μB. Medidas de magnetización en función del campo aplicado a T=50 K, muestran un débil comportamiento histerético, que corrobora el ordenamiento magnético presente a esa temperatura. Mediciones de la constante dieléctrica en función de la frecuencia aplicada a temperatura ambiente dan como resultado una alta constante dieléctrica relativa a bajas frecuencias (ε=780). La curva de reflectancia en función de la longitud de onda revela el comportamiento típico de un material de tipo perovskita doble y permite la obtención de la brecha de energía de 2,74 eV característico de un material semiconductor.

A Study of the Quantum Correlations in a Tavis-Cummings System
Authors: Madrid Úsuga Duvalier
Published: February 2018

The quantum correlations of two qubits in a microcavity with dissipation and a single quantized mode of the electromagnetic field are studied. In order to study our physical system, the Tavis-Cummings model and the formalism of the master equation of the density operator under the Born-Markov approximations will be used. The cavity mode will be coupled with an external pulsed laser and the master equation of the density operator that describes the evolution of the system will be solved numerically. The concurrence, the quantum mutual information, and the quantum discord are determined for the system of two qubits. The correlations are studied as a function of the dimensionless quantity $\tau = gt $ when the intensity of the laser cavity coupling varies, and two initial conditions are considered in the weak coupling regime in which the dynamic evolution of these correlations was studied.
O comportamento entre juros e crédito no Brasil para consumidores e produtores
Authors: Ishii Karlin Saori
Published: February 2018

O mecanismo de crédito viabiliza a atividade econômica moderna através da canalização de recursos para a produção e consumo. O canal de transmissão monetária de juros demonstra que taxas de juros afetam as decisões de tomada de crédito e, consequentemente, afeta a renda. O objetivo deste trabalho foi estudar o relacionamento entre juros e crédito no Brasil de março de 2011 a fevereiro de 2017 através de auto regressão vetorial. Os resultados indicam que os juros influenciam a tomada de crédito, porém o oposto praticamente não se verifica. Ademais, a tomada de crédito do setor produtivo (pessoa jurídica) reage mais a variações de juros que o setor consumidor (pessoa física).
Ensaio sobre transição alimentar e desenvolvimento em populações caboclas da Amazônia
Authors: Silva Rodrigo de Jesus , Garavello Maria Elisa de Paula Eduardo
Published: February 2018

Ensaio sobre transição alimentar e desenvolvimento aborda as consequências do processo de desenvolvimento socioeconômico nas populações caboclas da Amazônia. Usando a alimentação como indicador de transformação, o presente estudo faz asserções mais amplas, referentes aos impactos do estilo de vida moderno na cultura tradicional. Perante tais pressupostos o presente trabalho teve por objetivo discutir o processo de transição alimentar pelo qual os povos locais da Amazônia estão passando. Assim, conclui-se que as populações caboclas da Amazônia estão passando por um possível padrão de desarranjo da alimentação local por conta, principalmente, do acesso facilitado às cidades e do modelo assistencialista de políticas públicas.
The Brazilian Popular Restaurant Program as an integrated action for food security and health promotion: a user´s profile-oriented approach
Authors: Finco Fernanda Dias Bartolomeu Abadio , Finco Marcus Vinicius Alves
Published: February 2018

The Brazilian Popular Restaurant Program is a food security and nutrition action. O Program targets those who are considered the most vulnerable people, especially regarding socioeconomics and health conditions. The research aimed at assessing the Brazilian Popular Restaurant Program as an integrated action for food security and health based on a user´s profile-oriented approach. A cross-section survey was conducted in 2007 in Palmas-TO, Northern Brazil. Socioeconomic variables, food consumption and health conditions of the popular restaurants’ users were evaluated by questionnaire. Anthropometric measurements (height and weight) were also collected by trained researchers. A total of 600 users of the two units of the Popular Restaurant Programme in Palmas TO, Brazil, participated voluntarily to the study. Socioeconomic data describes that not all users fulfill the financial requirements to benefit from the program. A food pattern of users comprises a low fruit and vegetables consumption. Health and nutritional data indicates a relevant number of the users with monotonous diet and low physical activity level. The results point out that the Program needs to be improved specifically regarding development of health promotion towards the prevention of non-communicable diseases.
Determinantes do consumo da merenda escolar no Brasil: análise dos dados da PNAD de 2004 e 2006
Authors: Hoffmann Rodolfo
Published: February 2018

O objetivo deste trabalho é avaliar os efeitos de diversos fatores na probabilidade de um aluno consumir a alimentação servida na escola (“merenda escolar”), em unidades de ensino público (primeiro grau) que oferecem merenda. São utilizados os dados da Pesquisa Nacional por Amostra de Domicílios – PNAD, de 2004 e 2006, que adotou questionário suplementar com questões sobre educação e acesso à alimentação para moradores com até 17 anos de idade. Para alunos de escolas públicas de 1º grau, a proporção que frequenta escolas que oferecem merenda passou de 92,9% em 2004 para 96,7% em 2006. Ao mesmo tempo, nas escolas que oferecem merenda, a proporção de alunos que normalmente comem a merenda diminuiu de 84,0% para 82,0%. Os modelos de lógite estimados mostram que a probabilidade de consumo da merenda escolar é maior para residentes na área rural e decresce com a idade e com o aumento da renda. Essa probabilidade é maior para pretos e pardos do que para os brancos, sendo que a diferença de comportamento associada à cor é mais forte para meninos do que para meninas.
A produção agrícola e a atuação das Centrais de Abastecimento no Brasil
Authors: Cunha Altivo Roberto Andrade de Almeida , Belik Walter
Published: February 2018

Este artigo apresenta evidências das mudanças que estão se processando no aparato atacadista público de alimentos no Brasil abordando a evolução, as características atuais e as funções do sistema brasileiro de abastecimento. É realizada uma análise com base na observação dos dados coletados junto a 29 centrais de abastecimento públicas brasileiras em 2009 com informações sobre origem e destino dos hortigranjeiros comercializados nesses entrepostos a partir de uma amostra significativa. Os padrões sistêmicos podem ser observados através de dois aspectos: o desempenho da atividade econômica dos principais entrepostos atacadistas brasileiros e as funções remanescentes de reunião e distribuição da produção local e regional. Pretendemos demonstrar que o grupo de centrais públicas de abastecimento é bastante heterogêneo e que, de maneira geral, a dinâmica do seu crescimento é estabelecida “de fora para dentro”, sendo que muitos destes equipamentos não mais exercem papéis centrais como executores de políticas públicas voltadas para o abastecimento.
