Published: December 2019

Resumo: Este estudo objetiva verificar as percepções de estudantes de enfermagem sobre o uso de tecnologias digitais em sala de aula em uma Instituição de Ensino Superior do interior do Rio Grande do Sul, Brasil. Trata-se de um estudo descritivo e exploratório, com abordagem qualitativa. Participaram 31 estudantes da disciplina de Exercício Profissional, integrante do currículo específico do curso de graduação em enfermagem. A coleta dos dados ocorreu por meio da aplicação em sala de aula de questionário estruturado, com quatro perguntas sobre o assunto. Para a análise de dados, utilizou-se a Análise de Conteúdo teorizada por Bardin, para tanto, foram elencadas quatro categorias: O professor e suas tecnologias: as percepções dos alunos sobre o uso em sala de aula; Oportunidades do uso de tecnologias em sala de aula: a prática do professor a partir das percepções dos estudantes; Ensino e tecnologias: compreensões dos estudantes sobre sua relação; A formação em enfermagem e o uso de tecnologias: intersecções sobre o mercado de trabalho. Partindo da análise dos dados, é possível inferir que houve dois posicionamentos em relação aos estudantes, aqueles que percebem o uso da tecnologia como algo importante no dia-a-dia e outros que, ao contrário, não a utilizam com tanta profundidade para a sua aprendizagem.

Published: December 2019

O açaizeiro é uma palmeira de grande importância socioeconômica a nível nacional e, principalmente, regional, tendo o estado do Pará como o maior produtor. A alta demanda de mercado proporcionou o surgimento crescente de plantios comerciais de açaí, sendo alguns manejados com irrigação. No entanto, pouco se sabe sobre o manejo adequado do açaí, por exemplo, quanto a sua demanda hídrica. Conhecer a dinâmica dos elementos atmosféricos e suas relações com a planta é imprescindível para o uso racional de técnicas, como a irrigação. O poder evaporante do ar (Ea) é um parâmetro de grande relevância para compreensão da evapotranspiração. Objetivou-se com este trabalho analisar a variabilidade de Ea em um cultivo de açaí nas condições climáticas de Castanhal-PA. Para tanto, foi calculado o Ea para o município de Castanhal, em que os dados de Temperatura (°C), Umidade Relativa (%) e Velocidade do vento (m s-1) foram obtidos a partir de uma torre micrometeorologica instalada e instrumentada em um açaizeiro comercial localizado nas dependências da Fazenda Escola de Castanhal (FEC). Foi calculado o déficit de pressão de vapor (DPV) a partir da metodologia de Tettens e o Ea foi obtido em função da velocidade do vento. Obteve-se o valor médio de Ea de 0,31 mm d-1 (±0,13) para o período analisado. Os resultados encontrados condizem com os da literatura e reafirmam a importância do estudo do poder evaporante do ar para a estimativa da evapotranspiração.

EFEITOS DO TRABALHO SOBRE O ADOECIMENTO ENTRE AGENTES COMUNITÁRIOS DE SAÚDE - UMA REVISÃO DE LITERATURA
Authors: Santos Ladine Teixeira , Souza Fernanda de Oliveira , Pinho Freitas Paloma de Souza
Published: December 2019

Introdução: O trabalho dos Agentes Comunitários de Saúde (ACS) traz diversas novidades à atenção básica em saúde, destacando-se a obrigatoriedade de morarem e trabalharem na mesma comunidade. Objetivo: Compreender quais as efeitos do trabalho dos Agentes Comunitário de Saúde na saúde desses trabalhadores da atenção básica. Materiais e Método: Foi utilizada a estratégia de investigação da Revisão Integrativa da Literatura. Foram selecionados cinco artigos científicos, disponibilizados no portal de bases de dados Scientific Electronic Library Online (SciELO) utilizando descritores e palavras-chave como auxílio para a estratégia de busca. Resultados: A partir da análise dos textos, foi elaborada três categorias que apoiam as reflexões sobre os efeitos produzidos na saúde dos Agentes Comunitários de Saúde a partir do processo de trabalho, a saber: sobrecarga do trabalho; desgaste com a equipe de trabalho; ser trabalhador na comunidade que reside. Os resultados revelaram que estes profissionais que se dedicam a cuidar do outro, carecem de cuidar da própria saúde e suas condições de trabalho, muitas vezes, leva a um desgaste emocional. Conclusões: A pesquisa revelou que esses personagens, tão importantes na estrutura do serviço de saúde, como agentes modificadores do modelo assistencial vigente, não têm clareza do seu papel no sistema, sentem-se desvalorizados pelos gestores e pela comunidade. Isso exige que sejam implementadas políticas públicas que possam melhor avaliar o trabalho real desenvolvido pelos ACS e, a partir de um amplo diagnóstico, implementar ações que deem condições para que esses trabalhadores cumpram adequadamente sua função no Sistema Único de Saúde.

PERCEPÇÕES PATERNAS NO ACOMPANHAMENTO DO PRÉ-NATAL
Authors: BALICA LUCIANA OLIVEIRA , AGUIAR RICARDO SARAIVA
Published: December 2019

Introdução: O período gestacional compreende transformações no corpo e no cotidiano da mulher. É o momento de buscar atendimento especializado para o pré-natal e se preparar para o parto. Esse atendimento deve ser confiável, para que a gravidez se desenvolva de forma tranquila. Nessa fase também é fundamental que a gestante conte com pleno apoio familiar, principalmente do pai da criança. Objetivo: abordar a percepção dos pais sobre os possíveis benefícios proporcionados por sua presença ao pré-natal. Materiais e Métodos: trata-se de uma revisão integrativa da literatura, com busca de artigos na Biblioteca Virtual de Saúde (BVS). Os critérios de inclusão contemplaram publicações lançadas entre 2010 e 2017 e em língua portuguesa. Resultados: foram selecionados 20 artigos e sobre eles foi feita uma leitura exploratória, seguida de outra mais aprofundada com o objetivo de selecionar as informações pertinentes à pesquisa. O esforço ocasionou a elaboração de três categorias de análise: o ser homem diante da gestação da parceira; percepções sobre a participação paterna no pré-natal; e enfermagem, políticas públicas de saúde masculina e paternidade. Conclusões: a gestação constitui o momento no qual a construção da ideia de pai se inicia para o homem. Nisto, a participação paterna junto ao pré-natal é essencial para a boa compreensão de tal papel, bem como para avaliar a saúde em razão de doenças passíveis de detecção com a realização de exames. Entretanto, fatores culturais e profissionais tendem a afastar o homem do pré-natal.
Challenging the sponsor-proxy model: the Iran–Hizbullah relationship: a reply to Saad
Authors: Saouli Adham
Published: December 2019

This short piece responds to Saad’s ‘Challenging the sponsor-proxy model’. Saad’s article raises serious questions about the sponsor-proxy model. Saad successfully shows how the model reduces the ties between the sponsor and the proxy to material factors while striping the ‘proxy’ from its cultural and political agency. This, she shows, fails to capture the complex relationship that ties Iran to Hizbullah. While this attempt to problematise the model should be commended, the framework she proposes requires some further elucidation, which may offer important avenues to understand the Iran–Hizbullah connection.
Transnational securitisation of identity: distinctions between securitisation and ‘othering’ of Shias in Bahrain and Pakistan
Authors: Hafidh Hasan , Mehmood Maryyum
Published: December 2019

This paper aims to shed light on the phenomenon of transnational securitisation of identity and how it influences state-level securitisation and communal ‘othering’. We propose a more nuanced understanding of state-societal relations by viewing ‘othering’ as a by-product of various types of securitisation of identities, as opposed to the normative assumption within existing scholarship that applies these concepts interchangeably. This provides a more discernible lens through which certain cultural processes of discrimination are articulated, manifest and evaluated. The basis for our analysis is presented by comparing the persecution levelled against Shia communities within Bahrain and Pakistan, respectively. In the case of Bahrain, transnational securitisation amplifies pre-existing state securitisation, with external agents – in this context, Saudi Arabia – harnessing the hard power tactic of military intervention, as witnessed during the 2011 uprisings. Whereas in the case of Pakistan, transnational securitisation is performed by utilising soft power mechanisms, namely the legacy of petro-dollar wealth that has been used as a form of extremist proselytisation. The proliferation of jihadist non-state actors that pose an existential threat to Shia communities in Pakistan in recent years is a testament to this. In this way, the process bypasses state institutions to induce bottom-up, communal ‘othering’.
Faded networks: the overestimated Saudi Legacy of anti-Shi‘i sectarianism in Pakistan
Authors: Fuchs Simon Wolfgang
Published: December 2019

This article questions the often-assumed centrality of Saudi Arabia for the development of anti-Shi‘i sectarianism in Pakistan. I argue that those groups and individuals who have been most vocal about the Shi‘i ‘threat’ since the 1980s lacked (and continue to lack) any strong lineages with the Kingdom. Instead, their local polemics in Urdu foregrounded Pakistan as a political idea and global promise for Islam. This status of Pakistan’s self-view was acutely threatened by the Iranian Revolution of 1979 and the subsequent establishment of a religious state under the leadership of Ayatollah Khomeini. Consequently, Pakistani sectarian scholars transcended earlier Salafi-inspired arguments and tried to render Sunni Islam ‘fit’ to compete with powerful Shi‘i symbols. In doing so, they displayed a remarkable willingness to appropriate and rework Shi‘i concepts, something that is far from the mind of Saudi clerics.
Shi’i clerical networks and the transnational contest over sacred authority: dynamics in London’s Shi’i Triangle
Authors: Corboz Elvire
Published: December 2019

This article explores the transnational contest over sacred authority in contemporary Shi’i Islam as it plays out between contemporary maraji’ (sources of emulation) and the Iranian Supreme Leader, and in practice between their respective networks. It engages with existing assessments of the marja’iyya as an institution in crisis and argues instead that the marja’iyya has structural capacities that help maintain its potential in the face of the power exerted by the Supreme Leader. This in turns shapes the nature and outcome of the contest, including the need for the latter to accommodate with competing religious authorities. In the first part, the article offers a conceptualisation of the marja’iyya’s potential on the basis of three of its intrinsic features: its polycephalic nature and the broad temporal and geographical scope of a marja’’s authority. The second part offers a case study of the transnational contest over sacred authority in a specific locale. It maps the various (institutionalised) networks associated with Middle Eastern authorities, the Supreme Leader included, in London. Networks are however not hard-bound entities, as illustrated by the cross-networks navigation of their members. Furthermore, networks operate not only in competition but also in collaboration with each other. The contemporary contest over Shi’i authority is thus not a zero-sum game.
Islamic banking in the United Arab Emirates: Is embeddedness a contextual antecedent of performance and corporate governance outcomes?
Authors: Das Roshni
Published: December 2019

Research issue and theoretical foundation
 Embeddedness refers to the financial, operational and structural mooring of an organisation in a particular social system or community. It presents itself as a central tenet of Williamson's (1975) classic theory of Transaction
Cost Economics (TCE) and as such is a concept long overdue attention. In this paper, this concept is problematised as a macro- or organisation-level construct, and the paper also explores some of its consequents.
 Findings of the study
 Using a thick description
approach, case study evidence is built for the Islamic Banking (IB) business model. It is shown how this indigenous business model (i.e., IB) has leveraged the power of social networks to build a profitable portfolio of investments over time, in the specific context of the UAE (United Arab
Emirates) and its unique socio-political and cultural aspects. Dimensions of the embeddedness construct are proposed. Further, causal linkages are theorised with two distinct but inter-related consequents of embeddedness: corporate governance and performance outcomes of the organisation. It
is envisaged that both linkages are mediated by the construct of board interlocks.
 Implications
 Proximally, this study has the potential to extend scholarship in the domains of business relations, trust and indigenous business models. As a distal possibility, researchers
might use it to build on the organisational ecosystem paradigm.
 Scope and contributions
 The main contribution is to develop the concept of embeddedness. Additionally, this study uses the concept to build contextualised theory pertaining to the network characteristics
of an indigenous business model.
Towards a model of donor behaviour relating to mental disability charities
Authors: Bennett Roger , Vijaygopal Rohini
Published: December 2019

Purpose
 This paper extends and develops pre-existing "general" models of donor behaviour in order to create a fresh model useful for charities concerned with mental disability.
 Design/methodology/approach
 A comprehensive list of variables
with the potential to influence donors' behaviour relating to mental disability charities was assembled and then shortened via a random forest regression. Critical variables emerging from the regression were used to construct and test a model designed to predict donors' willingness to give
to a mental disability charity.
 Findings
 Certain variables commonly found in general models of giving (e.g., altruism, self-congruence) plus some variables specific to mental disability (e.g., stigmatic stereotyping, "protest" advertising) significantly affected
willingness to donate.
 Research limitations/implications
 The study employed random forest regression to identify "important" variables. Alternative approaches might have revealed relevant variables not covered by the present study. Donation intention rather than
actual giving was examined.
 Practical implications
 Mental disability charities need to frame their fundraising appeals in particular ways. "Protest" messages, social norms and self-congruity should be emphasised in campaigns.
 Social implications

Effective fundraising undertaken by the UK's (numerous) mental disability charities will generate the funds necessary for charities of this type to expand and improve their services to beneficiaries.
 Originality/value
 The research presents a fundraising model specifically
relevant to mental disability. It contributes to knowledge vis-à-vis fundraising for unpopular causes and lays down a framework for future research.
External serrodyne modulation for the suppression of low-frequency noise in quadrature interferometry
Authors: Michaud-Belleau Vincent , Charlet Mark , Tourigny-Plante Alex , Deschênes Jean-Daniel , Genest Jérôme
Published: December 2019

In interferometry, reaching a high signal-to-noise ratio at low frequencies can be challenging when the additive noise is nonstationary. Although this problem is typically solved by inserting a frequency shifter into one of the arms, in some cases, the interferometer cannot or should not be modified in this way. This Letter presents an alternative solution, based on external serrodyne frequency modulation, which is comparable to the typical approach in terms of complexity and performance yet does not require the modification of a passive interferometer. We demonstrate a prototype that achieves frequency shifting at 500 kHz with 89% power efficiency, leading to the wideband suppression of low-frequency additive noise by more than 19 dB. This enables a fully passive measurement of the thermoconductive noise of a 100 m single-mode fiber.
Fast peak-tracking method for FBG reflection spectrum and nonlinear error compensation
Authors: Wang Jindong , Huang Tingting , Duan Fajie , Cheng Qinrui , Zhang Fumin , Qu Xinghua
Published: December 2019

A universal method is proposed for fast tracking the peak wavelength of a fiber Bragg grating (FBG) reflection spectrum, which is the essential procedure of most FBG interrogators. Assuming the FBG reflection spectrum is sampled uniformly, we decompose the Moore–Penrose of the coefficient matrix into a formula that only contains a division and a dozen additions and multiplications; thereby, the cost of computation can be greatly reduced. Based on the analysis of the characteristics of the error introduced by the spectrum’s nonlinearity, we found and defined an error associated with the distance between the sampled peak and actual peak, and the compensating method for the error is also given. After compensation, the proposed method can speed up the tracking process 10 times or more without sacrificing the accuracy. An economical FBG interrogator with a commercial field programmable gate array (FPGA) and a microspectrometer was built up to verify the method, which was able to achieve a measurement frequency of 17 kHz.
Flexible random laser from dye doped stretchable polymer film containing nematic liquid crystal
Authors: Dai Guang , Wang Lei , Deng Luogen
Published: December 2019

Random lasers (RLs) offer new functionalities inaccessible with conventional lasers, such as an alterable shape and an easy integration with flexible optoelectronic devices. Here, we demonstrate a stretchable and threshold tunable RL by modulating the order degree of the nematic liquid crystal (NLC) that is caused by the alignment of polymer chain under tensile force. The lasing thresholds show a “U” shape curve variation trend, which is attributed to the competition between the partial orientation of the NLC molecules and the reduction of the dye and NLC densities. The results are further confirmed by the power Fourier transform (PFT) spectrum analysis. This work evokes deeper understanding of the effect of order degree on RLs and extends the applications of polymer polyvinylidene fluoride (PVDF) on tunable RLs.
Bright and highly-polarized single-photon sources in visible based on droplet-epitaxial GaAs quantum dots in photonic crystal cavities
Authors: Wei Yuming , Zhao Tianming , Yao Beimeng , Su Rongbin , Yu Ying , Liu Jin , Wang Xuehua
Published: December 2019

Solid-state single-photon sources with high purity, high brightness and a large degree of linear polarization are appealing to photonic quantum technologies. However, high-performance single-photon sources based on InAs/GaAs quantum dots (QDs) so far are operating at near infrared range, which limits the detection efficiency and potential compatibility with atomic quantum memory in visible. Here, we explore GaAs droplet epitaxial QDs emitting in visible to achieve bright, pure and highly-polarized single-photon emission via coupling to photonic crystal cavities.
Low-temperature carrier dynamics in MBE-grown InAs/GaAs single- and multi-layered quantum dots investigated via photoluminescence and terahertz time-domain spectroscopy
Authors: De Los Reyes Alexander E. , Vasquez John Daniel , Bardolaza Hannah R. , Lopez Lorenzo P. , Chang Che-Yung , Somintac Armando S. , Salvador Arnel A. , Jang Der-Jun , Estacio Elmer S.
Published: December 2019

The photocarrier dynamics in molecular beam epitaxy (MBE)-grown single- (SLQD) and multi-layered (MLQD) InAs/GaAs quantum dots were studied. Photoluminescence (PL) spectroscopy has shown that the MLQD has more uniform QD size distribution as compared to the bimodal SLQD. Correlation between PL and THz-TDS has shown that photocarrier transport is more favored in the MLQD owing to this uniform QD size distribution, resulting to higher THz emission. The THz emission from the QD samples were found to be proportional to temperature. A drift-related photocarrier transport mechanism is proposed, wherein photocarriers generated in the QDs are accelerated by an interface electric field.

Highly confining waveguides (

) without a degraded nonlinear coefficient and low propagation losses have been fabricated in lithium niobate (LN) by a new process that we called high vacuum vapor-phase proton exchange (HiVac-VPE). Index contrast, index profile, nonlinearity, and crystallographic phases are carefully investigated. Original analysis of index profiles indicates that the waveguides contain sub-layers whose depths depend on the exchange durations. Propagation behavior, propagation losses, and second-harmonic generation response of HiVac-VPE channel waveguides are investigated at telecom wavelength. The results recommend HiVac-VPE as a very promising technique for fabricating efficient nonlinear photonic integrated circuits in LN crystals.
Pos-Bolaño y Piglia: la nueva narrativa latinoamericana del siglo XXI
Authors: Villacorta Carlos
Published: December 2019

¿Cómo se ha articulado la literatura latinoamericana después de Ricardo Piglia y Roberto Bolaño? En el siglo XXI, una nueva generación de escritores apareció, renovando formas literarias y reflexionando sobre los cambios estructurales en sus países a partir del derrumbe de la izquierda (simbolizada en la caída del muro de Berlín, y en la consolidación del neoliberalismo en América Latina). Partiendo de la dialéctica Bolaño / Piglia, es decir del escritor en el exilio y/ o en la Academia, revisaré la nueva narrativa latinoamericana en Argentina, Chile, Perú y México que discute acerca de los restos de una ideología de izquierda y que, al mismo tiempo, propone una experimentación formal para su propia escritura. Desde la fetichización y nostalgia de la ideología de la izquierda hasta la reconstrucción de una clase media posdictadura, la nueva narrativa reflexiona desde la ficción y ensayo las posibilidades /los alcances de la literatura latinoamericana en el siglo XXI.
Chile, siglo XXI: cuando la generación de los hijos cuenta la dictadura
Authors: Duperron Celia
Published: December 2019

El objetivo de este artículo es presentar a tres autores chilenos que han crecido bajo la dictadura de Pinochet y que publicaron en la postdictadura. Estos autores nos parecen representativos de una generación de jóvenes autores que se desarrolla tanto en Chile como en Argentina. No se trata de hacer un recorrido de toda la producción chilena actual que es muy diversificada y rica, sino de centrarse en tres novelas en las que se evoca el periodo dictatorial. De hecho, lo interesante sera ver cómo los hijos cuentan la dictadura o más bien dicho cómo la dictadura se cuela en sus relatos del mismo modo que se cuela en el presente de Chile. En efecto, el pasado sigue siendo vivo en el presente del país y sigue estando presente en los diferentes discursos sea voluntaria o involuntariamente. O sea, cómo los autores chilenos actuales transcriben en el discurso ficticio de las novelas las relaciones de tensión que animan el legado del pasado e intentan crear una recomposición por cierto parcial, fragmentaria, caótica, conflictiva, de un pasado traumático nunca superado.
La literatura colombiana: ¿un problema de fronteras?
Authors: Bogoya Camilo
Published: December 2019

A partir del modernismo las literaturas latinoamericanas se liberan de un imperativo nacionalista, necesario para construir la idea de nación. En los inicios del siglo XXI, con el derrumbe paulatino de las fronteras, la fragmentación política, la atomización de los géneros, y al mismo tiempo con la tendencia a las narrativas globales y al ensanchamiento de los modos de vida y de producción, paradójicamente el siglo xix retorna: surgen de nuevo dos fuerzas que se convierten en un problema literario. Para los novelistas colombianos, la novela estaría a medio camino entre la vieja necesidad de construir un relato nacional, y la impronta de una estética desnacionalizada y global. ¿Cómo estas fuerzas terminan siendo el eje de una narrativa? Estudiaremos esta pregunta a partir de los ensayos de Pablo Montoya y Juan Gabriel Vásquez, así como de sus novelas Los derrotados y La forma de las ruinas.
Escribir en un país en ruinas: un panorama de la literatura venezolana actual
Authors: Vivas Lacour Carmen Victoria
Published: December 2019

El objetivo de este artículo es presentar un panorama de la literatura venezolana actual. Venezuela atraviesa una profunda crisis económica, social y política como consecuencia de la revolución bolivariana. Frente a esta, el campo literario se transforma e intenta mantener un espacio plural. Para analizar cómo las editoriales intentan sobrellevar el contexto nacional, estudiamos algunas publicaciones recientes y estrategias de publicación frente a la crisis, como, por ejemplo, el uso de las redes sociales y de las páginas web. Notamos, a pesar de importantes esfuerzos para mantener el mercado editorial, una dramática disminución en el número de publicaciones. Además, observamos que las editoriales en su esfuerzo de resistencia, terminan asumiendo múltiples roles como: promoción de lectura, labor de archivo, encuentros entre escritores de diferentes casas editoriales, organización de lecturas en público, alimentar sus redes sociales con contenido sobre historia de la literatura, hasta tirajes financiados exclusivamente con recursos personales. Sumado a esto, ocurre un importante éxodo de escritores, que, si bien permite a los autores hacer circular su obra a nivel internacional, no aumenta la oferta nacional. Todas estas adaptaciones del campo literario nos parecen insostenibles a largo plazo y lamentablemente no logran revertir la tendencia a un panorama literario precario y con muchas dificultades para la circulación de los textos
Sumisión y resistencia del cuerpo en «El central» de Reinaldo Arenas
Authors: Asencio Serrano Cristina
Published: December 2019

Reinaldo Arenas en su poema «El central» describe la subyugación a la que se ven sometidos los sujetos a lo largo de la historia de Cuba; privados de individualidad y convertidos únicamente en fuerza productiva mediante los mecanismos de opresión del poder. En este caso analizaremos de qué manera Arenas se centra en la corporalidad del indígena, el negro y el recluta para denunciar la sumisión que padecen y convertir el cuerpo en un dispositivo de resistencia.

Infertility and mental disorders in women. Communication 1
Authors: Tyuvina N. A. , Nikolaevskaya A. O.
Published: December 2019

This paper presents the definition, epidemiology, etiological factors, and approaches to classifying infertility and describes the relationship between mental health and infertility in women. The problem of idiopathic infertility is analyzed from both obstetric/gynecological and psychiatric positions. The psychological factors influencing the reproductive function of a woman are disclosed. Mental health disorders potentiating infertility are considered. Attention is paid to that mental disorders are insufficiently and untimely diagnosed in women with reproductive disorders, that certain forms of psychopathology are masked by functional gynecological disorders, and that obstetricians/gynecologists have no specialized ideas of women's mental health, which may lead to unsuccessful infertility therapy.
Acute coronary syndrome in a patient with transient ischemic attack: challenges of antithrombotic therapy (a clinical case)
Authors: Kovalchuk E. Yu. , Povzun A. S. , Kostenko V. A. , Brega A. V.
Published: December 2019

The paper presents experience with antithrombotic therapy in a critically ill patient with acute coronary syndrome and transient ischemic attack. It characterizes problems in triple antithrombotic therapy in a very ill patient with comorbidity. The paper demonstrates an incremental approach to choosing therapy according to the clinical picture of disease, an assessment of risk factors for ischemic and hemorrhagic complications over time, which is very important in the routine practice of a physician. It also shows how, based on existing recommendations, the optimal anticoagulant is chosen as part of triple and double antithrombotic therapy in terms of its potential risks and possible complications.
Current requirements for studies of drugs for the pathogenetic treatment of multiple sclerosis
Authors: Boyko A. N. , Spirin N. N. , Vlasov Ya. V. , Zakharova M. N.
Published: December 2019

More than 10 multiple sclerosis-modifying drugs (MSMDs) are widely used now. Novel MSMDs should be investigated in strict accordance with the evidence-based medicine principles governing clinical trials (of both original drugs and their analogues) that prove the high efficiency, safety, and tolerability of new drugs versus the already existing ones. Russia has gained extensive experience in conducting such studies using the well-known drugs as a comparison group. The efficiency and safety of new therapy should be evaluated according to the international criteria on the basis of a sufficient number of patients during a long-term follow-up. When combining the drugs, their efficiency and the risk of adverse effects can vary. The published results of a small study of the combined drug Leucovir (Belarus) do not meet these requirements, and the possibility of using this drug to treat multiple sclerosis can be discussed only after adequate phases II and III clinical trials.

Alzheimer's disease (AD) is the leading cause of dementia in the population. Difficulties in diagnosing AD have served as an incentive for actively studying different current methods that increase the accuracy of diagnosis of the current neurodegenerative process in this disease. One of these areas is the post-processing of magnetic resonance imaging (MRI) data, by exactly calculating the volume of various anatomical formations, namely MRI morphometry.Objective:to determine the possible relationship between the results of evaluating the higher brain functions and the reduction in the hippocampal volume calculated by MRI morphometry in AD patients with mild and moderate dementia and in healthy controls.Patients and methods.Examinations were made in 41 AD patients aged 70.63±8.38 years with mild and moderate dementia and in healthy individuals. All study participants underwent neuropsychological testing that included the Mini-Mental State Examination (MMSE), the frontal lobe dysfunction battery (FLDB); immediate and delayed 12-word recall trials (12-word test); Benton's revised visual retention test; test of literal and categorical associations; clock drawing test; and series number test, Part A. MRI was performed on a Siemens Magnetom Skyra 3T MRI scanner. Statistical Parametric Mapping software was used to convert images and the volume of the hippocampus was estimated by FMRIB Software Library.Results and discussion.A statistically significant decrease in hippocampal volumes was established in patients with AD compared with healthy individuals. No statistically significant differences in hippocampal volumes were found in patients with varying degrees of dementia. Patients with mild and moderate dementia differed in all indicators of neuropsychological tests, with exception for the 12-word test and Benton's test. There was a statistically significant correlation of the total volume of the hippocampi with the indicators of MMSE, FLDB, 12- word test, clock drawing test, and test of categorical associations.Conclusion.Hippocampal MRI morphometry in combination with neuropsychological tests is an informative technique in the diagnosis of AD. There is a relationship between the degree of hippocampal atrophy and the neuropsychological characteristics of patients.

The complex interactions of the epileptic focus and the brain systemic response require an integrated approach to predicting the course of focal epilepsy. Objective: to investigate the role of interictal neurophysiological parameters and neuroimaging data in predicting the course of epilepsy. Patients and methods. Eighty-two patients with focal structural epilepsy and 82 healthy participants (a control group) were examined. Clinical, psychological, and social characteristics and the data of neuroimaging and comprehensive neurophysiological studies (electroencephalography (EEG), recording exogenous and cognitive evoked potentials, motor testing, and heart rate variability) were assessed. Results and discussion. The investigators identified the prognostic factors of the unfavorable course of epilepsy: temporal lobe epilepsy, left temporal lobe lesion, nontraumatic intracerebral hemorrhages. They proposed algorithms for predicting the course of epilepsy based on neurophysiological and neuroimaging data. An analysis of physiological parameters in patients with the unfavorable course of epilepsy demonstrated the slowing of the background rhythm on the EEG, a decrease in the power of specific afferentation, and an increase in the decision-making time for the stimulus, as evidenced by the P300 potential, and insufficiency of the central mechanisms in providing a motor reaction. These patients also showed the enhanced activity of stress-implementing systems. Taking into account not only neurophysiological parameters, but also neuroimaging data could improve the prognostic capabilities of an artificial neural network that determines the type of a disease course. Conclusion. The unfavorable course of focal epilepsy is associated with a number of clinical and physiological parameters; in this case, it is possible to identify the specific physiological pattern of this course of the disease. The integrated clinical and physiological approach and neuroimaging data make it possible to successfully predict the course of the disease through machine learning technology.

Currently Instagram is not only a means of communication and information, but has plagued several sectors, especially marketing. One marketing that often happens on Instagram is sales, advertising, branding, and service. To support marketing activities, it needs to be done not only through conventional or old ways, but also should use social media to better reach all the desired consumers. This study aims to find out the focus on the use of Social Media Analytics tools on Instagram as a medium in increasing marketing effectiveness. This research is qualitative descriptive by using purposive sampling technique. Social Media Analytics that is implemented by Instagram in helping users of business profiles is by providing Insight features in which there are three functions, namely activity, audience and content provided in the form of data visualization. The utilization of the insight feature on Instagram has an important role in helping business users in increasing the effectiveness of marketing their products and services.

ABSTRAKSungai Kumbe memiliki sumberdaya ikan yang didominasi oleh ikan asli Papua yang merupakan bagian dari distribusi ikan-ikan paparan sahul seperti ikan duri (Neoarius graeffei), ikan mata bulan (Megalops cyprinoides) dan ikan tulang (Nematalosa flyensis). Karakteristik habitat Sungai Kumbe yang relatif masih alami dengan wilayah rawa banjiran yang luas pada musim penghujan menjadi keunikan tersendiri bagi keberadaan biodiversitas sumberdaya ikan. Hanya saja lingkungan perairan Sungai Kumbe telah mengalami tekanan yang berada pada kategori sedang akibat modifikasi lingkungan. Hal initentu akan berpengaruh terhadap keseimbangan habitat untuk pertumbuhan ikan dan larva ikan serta jangka panjang akan berdampak terhadap keberadaan stok dan biodiversitas sumberdaya ikan di sungai tersebut. Permasalahan ini didukung juga dengan belum adanya reservat atau suaka perikanan dan aktivitas penangkapan yangmasih dilakukan secara bebas sehinggakemungkinandilakukanjuga pada musim ikan paparan banjiran memijah.Tujuan penelitian untuk mengetahui pengelolaan yang tepat yang harus dilakukan di Sungai Kumbe untuk menjaga kelestarian sumber daya ikan.Penelitian dilakukan di Sungai Kumbe tahun 2014 dan 2015.Metode pendekatan lingkungan menggunakan metode STORET.Hasil penelitian menunjukkan bahwa untuk keberlanjutan sumberdaya perikanan di Sungai Kumbe diperlukan langkah-langkah pengelolaan yang meliputi (1) rehabilitasi hutan rawa, (2) penetapan suaka perikanan/reservat, (3) pengelolaan penangkapan, (4) pengembangan co-management. KATA KUNCI:Pengelolaan, sumberdaya ikan, Sungai Kumbe, Papua

Water balance is an estimate of the availability and needs of water in a watershed area. The water balance is very important considering the human need for water resources is a major requirement. The purpose of this study includes; (1) Analyzing the distribution of the influence of rainfall observation stations in each of the Ciliman sub-watersheds, (2) Analyzing the mainstay discharge in each Ciliman sub-watershed, and (3) Analyzing the potential availability of raw water in the Ciliman watershed. The types of data used in this study are secondary data including: (1) monthly rainfall data from 4 rainfall observation stations included in the Ciliman watershed, (2) climatological data from BMKG Taktakan Serang Station in 1998-2015, (3) Map of Watershed Ciliman and (4) Population data. Data analysis methods used include; regional rainfall analysis, analysis of water availability (evapotranspiration analysis, Mock model analysis), and analysis of water requirements. The results of the analysis showed that the highest rainfall occurred in January, and the lowest rainfall occurred in August. Overall, the water available in the Ciliman watershed is sufficient with the peak occurring at the beginning and end of the year. Water availability is estimated based on surface water discharge, where peak discharge occurs in January and minimum discharge occurs in August. The water balance in general in the Ciliman watershed is quite high with the highest water debit of 61.75 m3/s occurring in March and the lowest (minimum) discharge around 5.26 m3/s in August. The total water requirement for the Ciliman watershed area is 38.86 m3/s, consisti of; Water demand for irrigation is the highest water requirement reaching 37.96 m3 s with a total irrigated area reaching 5,423 hectares. Domestic water needs are 0.48 m3/s with a total population of 314,524 people served. Water requirements for industry are 0.000040 m3/s or relatively relatively small. While the water demand for the Tanjung Lesung Special Economic Zone is 0.42442 m3/s.

Published: December 2019

This pilot study examined the feasibility and acceptability of the HIV/AIDS self-management education program-Thai (HASMEP-T) for HIV-positive Thai men who have sex with men (MSM). HASMEP-T is a group-based adaptation of the evidence-based intervention, HASMEP. Participants were 40 Thai MSM living with HIV aged 18 years or older, recruited from an HIV clinic housed in a hospital in Thailand. Results support the feasibility of recruitment, screening, eligibility, and retention methods. The majority of the participants reported that the intervention was acceptable and met their initial expectations. Furthermore, all recruited participants in the intervention group (n = 20) completed HASMEP-T. Overall, intervention group participants demonstrated significant increases in all aspects of HIV self-management (p < .05), as well as improvement in quality of life in the psychological domain (p < .05). Our findings provide preliminary support for the large-scale, randomized-controlled trial of the efficacy of HASMEPT to promote self-management behaviors among HIV-positive Thai MSM.

Damage in biological neuronal networks triggers a complex functional reorganization whose mechanisms are still poorly understood. To delineate this reorganization process, here we investigate the functional alterations ofin vitrorat cortical circuits following localized laser ablation. The analysis of the functional network configuration before and after ablation allowed us to quantify the extent of functional alterations and the characteristic spatial and temporal scales along recovery. We observed that damage precipitated a fast rerouting of information flow that restored network’s communicability in about 15 min. Functional restoration was led by the immediate neighbors around trauma but was orchestrated by the entire network. Ourin vitrosetup exposes the ability of neuronal circuits to articulate fast responses to acute damage, and may serve as a proxy to devise recovery strategies in actual brain circuits. Moreover, this biological setup can become a benchmark to empirically test network theories about the spontaneous recovery in dynamical networks.
