Комплексирование инерциальной навигационной системы и глобальной навигационной спутниковой системы призвано обеспечить надежной, безопасной и устойчивой работоспособностью навигационные системы воздушного судна. Для достижения этого целесообразно подчеркнуть следующие требования: поддержание/обеспечение/сохранение точности параметров навигационных систем при длительной работе; обеспечение простоты и надежности алгоритма комплексирования навигационной системы, требующей низкой производительности обработки бортовыми компьютерами воздушного судна. Для удовлетворения вышеперечисленных требований применяется централизованный метод фильтра Кальмана, использующийся для компенсированной интеграции глобальной навигационной спутниковой системы и инерциальной навигационной системы в условиях слабой связи. Этот метод комплексирования, во-первых, довольно компактен в реализации, что значительно сокращает объем вычислений и упрощает сложность системы. Во-вторых, погрешность навигационных параметров инерциальной навигационной системы, вычисляемая алгоритмом дискретного фильтра Кальмана, возвращается в систему методом корректировки обратной связи, что устраняет проблему снижения точности навигационных параметров после длительной работы. Результаты этой работы представлены моделированием погрешности по скорости и положению воздушного судна в полете после фильтрации. Проверена устойчивость и эффективность предложенного алгоритма.

The integration of an inertial navigation system and the global navigation satellite system is designed to ensure reliable, safe and stable performance of aircraft navigation systems. To achieve this, it is advisable to emphasize the following requirements – maintaining / ensuring /preserving the accuracy of the parameters of navigation systems during long-term operation; ensuring the simplicity and reliability of the algorithm for integrating the navigation system, which requires low processing performance by on-board computers of the aircraft. To meet the above requirements, a centralized Kalman filter method was used, used for integration of global navigation satellite system and inertial navigation system systems in conditions of weak communication/signals. Firstly, this integration method is quite compact in implementation, which significantly reduces the amount of calculations and simplifies the complexity of the system. Secondly, IN Snavigation parameters error is calculated using the discrete Kalman filter algorithm, is returned to the system by the feedback correction method, which eliminates the problem of reducing the accuracy of navigation parameters after prolonged operation. The results of this work are depicted by modeling the error in aircraft navigation parameters in flight after filtering. The robustness and effectiveness of the proposed algorithm has been tested.

Представлены результаты компьютерного моделирования и прогнозирование механических свойств композитных материалов с поликарбонатной и полиамидной матрицей, наполненной короткими стеклянными включениями разной формы. Композитный материал будет использоваться для производства рабочего колеса насоса, поэтому должен обладать заданными механическими свойствами, а именно: уровень напряжений, возникающих в поперечном сечении колеса, должен достигать уровня 85 МПа. В программе DIGIMAT спрогнозированы уровни напряжений и инженерные характеристики материалов с полиамидной и поликарбонатной матрицей. На микроуровне исследовано влияние объема включений на механические свойства проектируемого композита. Установлено, что при соотношении размеров включений в пределах 468…60 частицы имеют игольчатую форму, и у материала с такими включениями предел напряжений и модуль упругости выше, чем при коэффициенте формы меньше 50, то есть когда форма включений приближена к сфере, и уровень прочности при такой форме достигает только 90 МПа.

The essay represents the results of computer modeling and prediction of mechanical properties of composite materials with polycarbonate and polyamide matrix filled with short glass inclusions of different shapes. The composite material will be used for the production of the pump impeller and mechanical properties should have the level of stresses arising in the cross section of the wheel in 85 MPA. The DIGIMAT program predicts stress levels and engineering characteristics of materials with polyamide and polycarbonate matrices. The influence of the volume of inclusions on the mechanical properties of the designed composite is investigated at the micro level. Moreover, it was found that with a ratio of the sizes of inclusions in the range of 468÷60, the particles have a needle shape and the material with such inclusions has a stress limit and elastic modulus higher than with a shape coefficient less than 50, in case, when the shape of the inclusions is close to the sphere and the strength level in this form reaches only 90 MPA.

Authors: Соловьев А.С. , Калач А.В.
Published: May 2022

Рассмотрены современные способы моделирования движения лавиноопасных снежных масс. Представлены результаты вычислительного эксперимента по моделированию движения снежной массы с позиций законов динамики поступательного движения. В рамках метода динамики частиц снежную массу представляли в виде совокупности одинаковых шарообразных элементов диаметром около 0,1 м. Показано, что трехмерная модель на основе динамики частиц позволяет получить высокую степень пространственной и временной дискретизации, что, в свою очередь, обеспечивает расчет траектории движения, энергии, давления снежной лавины. Таким образом, объемная дискретная модель снежной массы позволяет адекватно оценить разрушительное воздействие лавин.

The article discusses modern methods of modeling the movement of avalanche-prone snow masses. The results of a computational experiment on modeling the movement of a snow mass from the standpoint of the laws of the dynamics of translational motion presented. Within the framework of the particle dynamics method, the snow mass was represented as a set of identical spherical elements with a diameter of about 0.1 m. It shown that a three-dimensional model based on particle dynamics allows obtaining a high degree of spatial and temporal discretization, and this in turn provides calculation of the trajectory of motion, energy, and pressure of an avalanche. Thus, the volumetric discrete model of the snow mass allows us adequately assess the destructive impact of avalanches.

Работа посвящена исследованию возможностей численного решения задач вычислительной гидродинамики для трехмерного уравнения диффузии-конвекции на основе использования схем расщепления. Предполагается замена исходной задачи цепочкой двумерных и одномерных задач:для аппроксимации двумерной задачи диффузии-конвекции по горизонтальным направлениям – использование явной разностной схемы, для аппроксимации одномерной задачи диффузии-конвекции по вертикальному направлению – неявной схемы. Особое внимание уделено описанию механизмов численного решения двумерного уравнения диффузии-конвекции. С этой целью применены схемы, построенные на основе линейной комбинации разностных операторов схем «кабаре» и «крест» с весовыми коэффициентами, полученными в результате минимизации порядка погрешности аппроксимации. Предлагаемые в работе схемы расщепления являются физически оправданными и обладают свойством устойчивости. В рамках программной реализации параллельного счета представлен параллельный алгоритм, реализующий трехмерную задачу гидродинамики и переноса веществ на многопроцессорной вычислительной системе с использованием гибридной технологии MPI+OpenMP. Выполнено сравнение эффективности расчетов, проводимых на основе технологии MPI и гибридной технологии MPI+OpenMP.

The work is devoted to the study of the possibilities of the numerical solution of computational fluid dynamics problems for the three-dimensional diffusion-convection equation based on the use of difference schemes of a special type - two-dimensional - one-dimensional splitting schemes. Under these assumptions, it is assumed that the original problem is replaced by a chain of two-dimensional and onedimensional problems. To approximate the two-dimensional diffusion-convection problem in horizontal directions, it is assumed to use an explicit difference scheme, and to approximate the one-dimensional diffusion-convection problem in the vertical direction, an implicit one. Particular attention is paid to the description of the mechanisms for the numerical solution of the two-dimensional diffusion-convection equation. For this purpose, schemes are applied, built on the basis of a linear combination of difference operators of the “cabaret” and “cross” schemes with weight coefficients obtained as a result of minimizing the order of the approximation error. The splitting schemes proposed in this work are physically justified and have the property of stability. As part of the software implementation of parallel computing, a parallel algorithm is presented that implements the three-dimensional problem of hydrodynamics and the transfer of substances on a multiprocessor computer system using the hybrid technology MPI + OpenMP. Comparison of the efficiency of calculations based on MPI technology and hybrid MPI + OpenMP technology is carried out.

Published: May 2022

Статья посвящена компьютеризации исследований литологического состава и свойств горных пород по фотографиям керна. Современная оптическая микроскопия позволяет получать высококачественные фотографии образцов пород. Сложность их компьютерного анализа обусловлена высокой неоднородностью и изменчивостью цветовых характеристик литотипов и свойств, отсутствием единого цветового классификатора. Проанализированы разработки по автоматической и полуавтоматической классификации фотографий керна. Предложена схема компьютерной оценки параметров пористости и трещиноватости по фотографиям петрографических шлифов: полуавтоматическое выделение пустот по цветовым признакам; автоматическое выделение трещин по геометрическим признакам; расчет параметров общей пористости, суммарной длины и средней ширины трещин. Схема реализована с использованием алгоритмов библиотеки OpenCV, интегрированных в пользовательское программное приложение, и опробована на реальных данных.

The article is devoted to the computerization of studies of the lithological composition and properties of rocks based on core photographs. Modern optical microscopy allows obtaining high-quality photographs of rock samples. The complexity of their computer analysis is due to the high heterogeneity and variability of color characteristics of lithotypes and properties and the lack of a unified color classifier. The article analyzes the development of automatic and semi-automatic classification of core photographs. A scheme for the computerized assessment of porosity and fracture parameters based on photographs of petrographic thin sections shall be proposed: semi-automatic selection of voids by color; automatic selection of cracks based on geometric features; estimation of parameters of absolute porosity, total length and average width of cracks. The scheme is implemented using algorithms of the OpenCV library, integrated into a custom software application, and was tested on real data.
Optimizing the transformer model for speech recognition
Authors: Чучупал В.Я.
Published: May 2022

Применение нейросетевых моделей «кодер – декодер с вниманием» в системах распознавания речи обеспечивает высокие показатели точности. К существенным ограничениям этих моделей относятся: отсутствие режима реального времени и большая вычислительная сложность (количество операций и объем требуемой памяти). Формально сложность алгоритма вычисления функции самовнимания растет пропорционально ( ) 2 O n , где n – количество элементов слоя сети. Использование физических свойств речевого сигнала позволяет построить такой алгоритм вычисления функции самовнимания, который имеет оценку сложности O n( ) и при этом рассчитан на потоковую обработку сигнала, в том числе работу кодера трансформера в реальном масштабе времени.

The use of neural models “encoder – decoder with attention” in speech recognition applications provides high recognition accuracy rates. The significant limitations of these models include the lack of streaming mode and high computational complexity (in terms of the number of operations and the amount of memory). Formally, the complexity of the self-attention algorithm grows as 2 O n( ), where  n  is the number of elements in the attention layer. The use of the physical properties of a speech signal makes it possible to construct such an algorithm for calculating the self-attention of Transformer’s encoder, which has the complexity as low as O n( ) and at the same time is suitable for recognition in streaming and realtime operation modes.

Automatic Lemmatization of Old English Class III Strong Verbs (L-Y) with ALOEV3
Authors: Torre Alonso Roberto
Published: May 2022

This article presents ALOEV3, a lemmatizer based on Morphological Generation that allows for the type-based automatic lemmatization of Old English Class III strong verbs beginning with the letters L–Y. The lemmatizer operates on the basis of the inflectional, derivational and morpho-phonological alternation rules characteristic of this class. The generated form-types are checked against the two most reputed Old English corpora, namely the Dictionary of Old English Corpus and The York-Toronto-Helsinki Parsed Corpus of Old English Prose to validate their attestations and assign the corresponding lemma. Results show that 97 percent of the validated forms are successfully assigned a single lemma. The remaining inflectional forms (38 out of 1,256) show competition between two lemmas, which implies that despite the high level of accuracy of the lemmatizer, contextual, token-based analysis is still needed for disambiguation. However, the research shows that competition only occurs in a limited set of lemma pairs and their derivatives. Although the research focuses on but one strong verb class, it confirms that exploring the avenues of automatic lemmatization will contribute to the field of Old English lexicography by either lemmatizing attested inflectional form types or by highlighting areas for manual revision.
Thermo-hydraulic characteristics of mixed convection of transition flow in a conduit at different tilts
Authors: ONI Taiwo O.
Published: May 2022

In this study, numerical investigation was carried out on combined free and forced convection for transition flow of water in a conduit that has a mechanical component, which is a three-sided-polygon-perforations-tranverse-axes tape, inserted in its interior. The purpose of the investigation is to find out the thermo-hydraulic characteristics of mixed convection of transition flow in the tube, and compare them with those of forced convection. Fluent software was used to perform the numerical investigation for the transition flow at Reynolds number (Re) in the range 2,150≤Re≤3,700 for the tube bent at sundry tilts (λ) in the range〖 15〗^o≤λ≤〖 90〗^o. The results indicated that the inside temperature and surface temperature of the tube whose fluid flow is forced convection are lower than the case of the tube whose fluid flow is mixed convection, and that the temperatures (tube’s inside temperature, dimensionless outlet temperature, and surface temperature) increase as the tube tilt increases. Not only that, as the tube tilt increases, the dimensionless outlet temperature increases, but the outlet velocity decreases. The Nusselt number in the tube whose fluid flow is forced convection is lower than the case of mixed convection. For the tube with flow tilts of 15^o,30^o,〖 60〗^o, and 90^o, the Nusselt number are 4.01 to 6.10%, 4.60 to 7.41%, 5.32 to 8.71%, and 6.31 to 10.12%, respectively, greater than the case of the tube whose fluid flow is forced convection, for the Reynolds number considered. The validation of the numerical work with an experimental work confirms the correctness of the numerical work.

Contrarrevolução bolivariana na história recente da Venezuela
Authors: Damasceno Fernando Sérgio , Coelho Wanderson de Oliveira
Published: May 2022

RESUMO

Este artigo lança luz sobre sucessivas tentativas de golpes contra Chávez, entre 2001 e 2003, todas derrotadas pelo movimento operário venezuelano. Destacam-se o golpe de 11 de abril de 2002, o lockout petroleiro de dezembro do mesmo ano e a reação dos trabalhadores a partir da refinaria de Puerto La Cruz, onde se estabeleceu o controle operário da produção. O objetivo aqui é, por um lado, resgatar a consciência histórica desse movimento, que protagonizou o maior feito de caráter revolucionário do século XXI; por outro, elucidar o papel de Chávez e do movimento bolivariano na contrarrevolução. Para subsidiar essa discussão, utilizamos pesquisa bibliográfica de estudiosos da temática, principalmente, a obra A face oculta da Venezuela: do controle operário da produção à hegemonia de Chávez. Ademais, o materialismo histórico-dialético norteia as argumentações aqui apresentadas.

Palavras-chave: Movimento popular e operário. Ascensão Chavista. Contrarrevolução.

A crise que hoje atormenta a Venezuela

repercute no intenso deslocamento

forçado de pessoas que se testemunha e

em um Estado que implode. Porém, tão

importante quanto avaliar as repercussões

da crise é identificar as causas estruturais

da mesma. Com este intuito, neste artigo

abordaremos a interface entre rentismo

e crise na Venezuela, com o objetivo de

contribuir para um esforço de compreensão

mais longitudinal, capaz de contemplar as

continuidades e rupturas concernentes ao

funcionamento do Estado e da economia

venezuelanos contidas no quadro da crise

atual, por meio de uma análise pautada na

revisão bibliográfica das produções que

discutem a história venezuelana. Para isso

percorremos três momentos distintos da

história venezuelana: a ascensão e queda

do pacto de Punto Fijo; a Venezuela sob

Chávez; e a Venezuela pós-Chávez. Ao

final, argumentamos que a crise atual tratase

de uma crise oriunda das tecnologias

rentistas não superadas pelo projeto

bolivarianista.

DA DISTENSÃO POLÍTICA À NOVA REPÚBLICA: APONTAMENTOS SOBRE A VITÓRIA OPOSICIONISTA NO COLÉGIO ELEITORAL
Authors: Salomão Ivan
Published: May 2022

A abertura política promovida pelo regime militar remonta ao governo Geisel (1974-1979). Do início da distensão ao anticlímax representado pelo falecimento do presidente eleito no Colégio eleitoral, o processo de redemocratização enfrentou distintos desafios. Baseado na percepção de que o regime discricionário não poderia mais se legitimar no robusto crescimento de outrora, o restabelecimento da normalidade político-institucional sobreviveu às restrições da chamada “linha-dura” do exército, fortaleceu-se com a campanha das “Diretas-já” e assistiu, por fim, à articulação que levou José Sarney à chapa oposicionista. Abandonado pelas lideranças políticas, Sarney viu-se obrigado a buscar nas ruas a legitimação que faltava ao seu governo.
REALIDADE E PERSPECTIVAS DE ACESSO AOS BENS DOCUMENTAIS E À INFORMAÇÃO NAS IFES DO ESTADO DE RORAIMA
Authors: Rosa Tatiana Costa , Baptaglin Leila Adriana
Published: May 2022

A presente investigação objetivou compreender a atual situação do acesso ao patrimônio documental e à informação. Para isso, foram realizadas pesquisas de campo, utilizando-se entrevistas abertas, diretamente com os sujeitos envolvidos com a gestão documental e o acesso à informação das Instituições Federais de Ensino Superior do Estado de Roraima: o IFRR e a UFRR. As narrativas dos sujeitos entrevistados foram compreendidas por meio da análise do conteúdo, segmentada em duas categorias, as quais foram elaboradas com base em dois tópicos guias pré-estabelecidos no roteiro da entrevista, são elas: 1. Acesso, na qual contempla-se aspectos acerca do acesso aos documentos e à informação das IFES e 2. Perspectivas, na qual explana-se sobre as perspectivas e o desenvolvimento de futuras ações destas instituições frente ao acesso e ao patrimônio documental. Por meio dos resultados obtidos constatou-se que o acesso vem ocorrendo, ainda que não de forma satisfatória e as perspectivas voltadas aos bens documentais e ao acesso a eles e às informações são promissoras nas IFES do Estado de Roraima.
NARRATIVAS DO COTIDIANO DE UM CUIDADOR FAMILIAR DA ESPOSA EM SOFRIMENTO PSÍQUICO
Authors: Batista Eraldo Carlos
Published: May 2022

O cuidador familiar da pessoa em sofrimento psíquico vive constantes mudanças em seu cotidiano, tendo que se adaptar constantemente às novas formas de condução de suas atividades diárias. O objetivo com este artigo foi fazer uma análise de narrativa de uma entrevista autobiográfica de um cuidador familiar da esposa em sofrimento psíquico. Utilizou-se como abordagem metodológica a pesquisa qualitativa sob a perspectiva da narrativa autobiográfica. Da análise das narrativas emergiram cinco eixos temáticos: a dificuldade na adaptação ao papel de cuidador; a sobrecarga familiar; a abdicação da vida social; o sentimento de culpa e o cuidar como fator preditor de adoecimento. O texto autobiográfico mostra que na trajetória como cuidador familiar o informante passa por um momento de enfrentamento e dificuldades para lidar com a situação. Além disso, a falta de habilidade com essa nova função provocou não somente um desgaste físico como também emocional, levando seu João a um estado de estresse.
DESLOCAMENTOS MACUXI E WAPICHANA EM BOA VISTA – RORAIMA: PERSPECTIVAS A PARTIR DA ANCESTRALIDADE
Authors: Melo Luciana Marinho
Published: May 2022

Neste artigo abordo a presença dos povos indígenas pertencentes às etnias Macuxi e Wapichana no contexto urbano da cidade de Boa Vista, Roraima, a partir da perspectiva da ancestralidade. O argumento que apresento ao longo do texto é de que a circulação de pessoas autodeclaradas indígenas na capital roraimense é justificada por meio de uma compreensão de território que transcende os limites políticos de fronteiras estabelecidos pelo Estado brasileiro. Este entendimento não é compartilhado pelos demais citadinos, tampouco pelos agentes do Estado, que consideram ilegítima a permanência de povos indígenas na cidade, desencadeando manifestações racistas direcionadas a este último. No texto, apresento os posicionamentos dos agentes do Estado, bem como as estratégias adotadas pelas lideranças Macuxi e Wapichana para reconhecimento da presença indígena em contexto urbano.
VENEZUELA ENTRE LA HEGEMONÍA Y LA CONTRA-HEGEMONÍA (UNA LECTURA CONTEXTUAL PARA COMPRENDER UNA COMPLEJIDAD SOCIO-HISTÓRICA)
Authors: Fernández Adrián Padilla
Published: May 2022

En el artículo se realiza un ejercicio de reconstrucción histórica que intenta responder a la problematización en torno al cuadro conflictivo venezolano de la contemporaneidad, el cual se ha convertido en foco de atención de los más diversos medios de comunicación que a escala mundial contribuyen en la construcción de una matriz informativa que configura lo que se conoce como “opinión pública internacional”. Se parte de la premisa de que para comprender la complejidad socio-histórica que está implicada en esa realidad es necesario considerar la condición de Venezuela como país petrolero, valorar su localización geopolítica en el contexto de la acción hegemónica de los Estados Unidos y, de igual modo, se debe reflexionar sobre los efectos de la crisis global del modelo capitalista y la emergencia de nuevos polos que van configurando nuevas hegemonías dentro de las dinámicas del capitalismo global. Finalmente, se destaca el papel de un pueblo que como sujeto colectivo se enfrentó hace 200 años a uno de los factores de poder más significativos de su tiempo como lo fue el Estado monárquico español, y que hoy está en el ojo del huracán de una confrontación que pudiera tener una peligrosa expresión a escala planetaria.
O HORIZONTE COMUNICATIVO DA MIGRAÇÃO VENEZUELANA NA CIDADE DE BOA VISTA - RORAIMA
Authors: Morais Vângela Maria Isidoro de , Lima Damião Marques de
Published: May 2022

A cidade informa. Esta afirmação que está no centro da escrita do presente artigo é direcionada para refletir o processo migratório de venezuelanos para o Brasil, no cenário de Boa Vista, capital de Roraima. A abordagem se baseia em duas questões fundamentais: o que os estímulos visuais da cidade comunicam? E como os migrantes venezuelanos constroem e significam essa experiência em ruas, esquinas, praças e outros espaços públicos? Sob a forma caminhante, organizam-se as apropriações simbólicas entre o que diz o olhar mais panorâmico sobre a urbe e as narrativas dos migrantes. Um campo analítico, baseado em algumas situações concretas, onde a percepção visual e a vivência dos sujeitos se amalgamam na elaboração de uma interpretação possível a partir desses fluxos e tensões culturais.

UMA ANÁLISE ECONÔMICA DO DIREITO SOBRE A PRÁTICA DO ABORTO: UMA PROPOSTA ALTERNATIVA AO ATUAL MODELO BRASILEIRO DE ENFRENTAMENTO
Authors: Coêlho Marcial Duarte
Published: May 2022

Este artigo pretende lançar mão da dita Análise Econômica do Direito (AED) sobre uma questão em específico: a polêmica decisão estatal que envolve a legalização ou não do aborto, especialmente no Brasil. De início, são demonstradas as balizas gerais a respeito da AED, notadamente sua metodologia, seus caracteres positivo e normativo, e uma de sua pedras-chaves – a eficiência. Após, vai-se ao panorama, no Brasil e em alguns lugares do mundo, sobre a questão do aborto. Vê-se como seu enfrentamento é malsucedido no Brasil. A AED, com seu espírito descritivo, demonstra que em outros países, que optaram pela legalização responsável, tal prática vem ajudando a diminuir as práticas abortivas, com um grande ganho também para a saúde física e mental das gestantes que optaram (ou não) pela interrupção. A legalização, todavia, há que ser combinada com outras políticas amplas multissetoriais, que envolvem planejamento familiar, métodos contraceptivos, orientação médico, psicológica, social e jurídica, além de respaldo às crianças recém-nascidas, com a criação de creches, benefícios sociais para os hipossuficientes, etc.
Ciudadanía y derechos sociales en América Latina frente a las transformaciones neoliberales. ¿Qué hacer?
Authors: Campos Luiz
Published: May 2022

En esta conferencia se aborda la cuestión de la ciudadanía y los derechos sociales en América Latina frente a las transformaciones neoliberales. A partir del inicio de la década de los años 90 los procesos de democratización avanzaron en América Latina lo que produjo un nuevo marco de reconocimiento de derechos de los pueblos indígenas y de afrodescendientes. Estas conquistas se han enfrentado en los últimos años a un nuevo avance del capitalismo y a la agudización de políticas neoliberales y extractivistas que han venido a amenazar la forma en que se concibe la ciudadanía intercultural y las relaciones interétnicas. Se reflexiona a partir de diversos casos que abordan la realidad de migrantes, afrodescendientes, indígenas desplazados y lo que permite reflexionar acerca de la interculturalidad, la migración, el racismo y el reconocimiento en América Latina y del papel que deben jugar las ciencias sociales en estos procesos.

Pattern of adverse drug effects reported by patients being treated in a tertiary healthcare institution in North India: A retrospective observational study
Authors: Kansal Dinesh , Patiyal Nitin , Gautam Abhishek , Chauhan Ankita , Bodh Suman
Published: May 2022

: Patient safety and well-being is favored by reporting adverse drug effects timely and precisely. Pharmacovigilance contributes to post-marketing surveillance and ensures that necessary changes may be done to the drug labels accordingly.

: The study was aimed at observing, analyzing and reporting various adverse effects due to prescribed drug intake for patient conditions and disease being treated at our tertiary healthcare institution.

: Study was conducted at Dr. RPGMC, Kangra at Tanda, which is a multi-specialty tertiary healthcare hospital with 700 beds and an ADR monitoring Centre situated in the lap of western Himalayas in North India. Pattern of ADRs reported by the volunteers receiving drug therapy from January to December 2021 was assessed. Data pertaining to age, gender, drug intake, types of ADRs, treatment and outcome of the reactions was collected. Individual assessment was done for each patient. WHO scale was used for causality assessment. ADR profiling was carried out based on site, onset, organ system affected, duration, whether urgent referral was required or not and resolution of signs & symptoms.

The data was analyzed using Microsoft excel 2019 and expressed as mean ± standard deviation & percentages.

: A total of 83 patients reported ADRs (adverse drug reactions). These were reported to IPC, Ghaziabad through our AMC (Adverse Drug Reaction Monitoring Centre) from 1 January 2021 to 31 December 2021. Gastro-intestinal system related adverse effects (35%) were most common followed by skin (22.9%) and CNS (12%) adverse effects. GI adverse effects included anorexia, dyspepsia, diarrhoea, oral ulcers, nausea, vomiting, weight-loss and raised liver function tests.

: ADRs occur commonly but are often undetected. Even if detected they remain underreported as most of the health care professionals are unaware about pharmacovigilance. Therefore, mass sensitization and reward to those who report ADRs vigilantly is the need of the hour to promote patient safety.

Prevalence of care dependence among older persons in 26 Latin American and the Caribbean countries
Authors: Aranco Natalia , Ibarrarán Pablo , Stampini Marco
Published: May 2022

The rapid aging of the population will cause a sharp increase in the demand for dependency care services in Latin America and the Caribbean. In order to inform policy-making, in this study we present novel estimates of the number of dependent older people in 26 countries in the region. For 10 of these countries, estimates are based on existing survey data. For the remaining 16, we used a statistical model to predict the prevalence of dependency care based on the relationship between this condition and age, sex, and health status. The number of dependent older people in the years 2035 and 2050 is also estimated. On average, we find that 14% of the population over 65 years of age was dependent in 2020, and this figure is projected to grow to 16% in 2050. Driven above all by the increase in the elderly population in the region, the number of dependent older people is expected to almost triple in the same period, from 8 million in 2020 to 23 million in 2050.
