Published: April 2022

Objectives: Despite widespread use of smokeless tobacco (ST) in Pakistan, a very limited empirical evidence have been reported regarding its impact on the coronary anatomy and obstructions. Therefore, this study was conducted to compare the coronary angiographic profile of smokeless tobacco (ST) users and smokers with non-tobacco users presented with acute myocardial infarction (AMI).
Methodology: Consecutive patients with AMI were stratified in to four groups as tobacco non-users (G1), solo ST users (G2), both smoking and ST users (G3), and solo smokers (G4). Coronary angiographic findings regarding number of diseases vessels and infarct related artery were recorded.
Results: Out of 326 patients, ST users were 28.2%(92), 6.4%(21) in conjunction with smoking and reaming 21.8%(71) without smoking. Females were 19.7%(14/71) of G2, 4.8%(1/21) of G3, 0% in G4. Young patients (≤ 40 years) were 3.4%(5/149) of G1, 9.9%(7/71) of G2, 14.1%(12/85) of G4, and 23.8%(5/21) of G3 cumulatively making 82.8%(24/29) of the young patients. Single vessel disease (SVD) and left anterior descending artery (LAD) were significantly higher among ST user as compared to non-users with distribution of 46.7% vs. 34.2% and 70.7% vs. 56.4% respectively.
Conclusion: The distribution and localization of involved vessels among ST users with AMI are same as that of smokers with SCD and LAD as infarct artery as the common findings. Tendency of ST use is also high among female patients and Tobacco use in either form, smoking or smokeless, is alarmingly high (>80%) among young (≤40 years) patients with AMI.

Objectives: Contrast induced nephropathy (CIN) is a common complication and found to be associated with increased morbidity and mortality after primary percutaneous coronary intervention (PCI). The objective of this study was to validate the Mehran Risk Score (MRS) for the risk stratification of CIN in patients undergone primary PCI.
Methodology: A cohort of consecutive patients undergone primary PCI at a tertiary care cardiac center were included for this study. Patients in Killip class IV at presentation, patents history of any PCI, and chronic kidney diseases were excluded from this study. MRS was calculated at baseline and post procedure serum creatinine level increase of either 25% or 0.5 mg/dL was taken as CIN.
Results: A total of 547 patients were included, of which 79.3%(434) were male. CIN after primary PCI was observed in 62(11.3%) patients. The area under the curve (AUC) for the MRS was 0.712 [0.641 to 0.783]. Cut-off value of ≥6.5 had sensitivity of 61.3% [48.1%-73.4%] with positive predictive value of 21.2% [17.5%-25.6%] and specificity of 70.9% [66.7%-74.9%] with negative predictive value of 93.5% [91.3%-95.2%]. MRS ≥6.5 was found to be an independent predictor on multivariable analysis with adjusted odds ratios (OR) of 3.86 [2.23-6.68] along with multi-vessel diseases with OR of 2.31 [1.27-4.19].
Conclusion: MRS has shown to have a good discriminating power. However low positive predictive value of the optimal cutoff value of ≥6.5 for prediction of CIN suggests need of modification to the MRS to improve its clinical utility in the modern era of primary PCI.

Published: April 2022

Spatial data mining is a technique mainly used for predictive analytics. Data mining is the method of determining necessary samples from spatial datasets using machine learning methods. But, the existing prediction methods failed to forecast accurately with more accuracy and reduced error. A Random Forest Correlation based Fuzzy classification technique is introduced to improve the spatial data classification and error reduction. The algorithm constructs a random forest and the correlation is measured between the training and testing features. A fuzzy rule based classification is performed for classification into subsets. The proposed method takes forest fire dataset as input and evaluates the parameters such as classification accuracy, space complexity and classification time. The output is a subset of classes of fired and non fired region with enhanced classification accuracy, minimal false-positive rate and reduced time complexity.

Published: April 2022

Com o intuito de analisar o potencial de geração de energia elétrica fotovoltaica no estado de Mato Grosso, foram analisados os dados de radiação solar de 20 cidades no período de 2012 a 2014, fornecidos pelo Instituto Nacional de Meteorologia (INMET). Com esses resultados foi possível calcular a geração de energia fotovoltaica por uma placa fictícia de 1m² e 15% de eficiência. De forma a se fazer uma análise espacial, utilizou-se da geoestatística para se fazer um semivariograma e um mapa de krigagem. A média do potencial geração de energia fotovoltaica do estado é aproximadamente 0,73 kWh por dia para cada m². O maior potencial de geração de energia ocorre no nordeste do estado, na cidade de Carlinda, com aproximadamente 0,815 kWh por dia para cada m², e em Cuiabá é verificado o menor potencial de geração, 0,46 kWh por dia para cada m², 37% menor que a média do estado. Fatores como poluição, queimadas e relevo podem diminuir o potencial de geração de energia fotovoltaica da capital de Mato Grosso.
Cálculo dos benefícios energéticos da geração distribuída solar fotovoltaica
Authors: Susteras Guilherme , Susteras Alexandra
Published: April 2022

O mercado brasileiro de geração distribuída (GD) está crescendo a taxas aceleradas, especialmente desde 2016, quando novas regras foram introduzidas pela agência reguladora (ANEEL). Com a publicação da Lei 14.300/2022, caberá ao Conselho Nacional de Política Energética (CNPE) determinar diretrizes para que a ANEEL especifique o modelo tarifário a ser aplicado a partir de 2029, considerando o balanço adequado entre custos e benefícios da GD para toda a sociedade, especialmente para aqueles consumidores que não podem ou não querem instalar seu próprio sistema de geração. Entretanto, durante o debate para formular as novas regras, ficou evidente que existe uma falta de metodologias que adequadamente quantificam os benefícios da GD para o sistema brasileiro de energia. Este trabalho oferece uma metodologia que considera os impactos positivos da GD na redução do custo total de operação decorrentes da redução de necessidade de acionamento de usinas termoelétricas e da redução das perdas técnicas nas redes de transmissão e distribuição. A metodologia possui duas principais vantagens: foi concebida baseada nas condições reais do sistema brasileiro, evitando assim a necessidade de adaptar metodologias existentes para as características locais, e é baseada em informações púbicas, evitando assim potencial risco de assimetria de informação. A análise foca no caso de geração solar fotovoltaica, que representa mais de 97% da capacidade instalada de GD no Brasil. Como resultado, estimamos que para cada 1 MWh gerado por GD, o custo total do sistema foi reduzido em R$ 270 em 2019 e R$ 347 em 2020.

Arteriovenous malformation of head and neck: A case report
Authors: Hussain Tahir , Farooqui Fareeha , Jehan Meher
Published: April 2022

Extra-cranial arteriovenous malformations of head and neck are rare and may present with acute haemorrhage. Their management varies and requires a multidisciplinary approach. Intra-arterial embolisation alone or followed by surgery is recommended. We present here a case of a huge pulsatile lesion extending from the neck to the temporo-parietal region with the main feeding vessel being the right external carotid artery. It was treated with surgical resection only as the feeding artery was very tortuous making selective embolization of artery impossible. The excision of the portion of the artery in the neck was carried out a week later. The patient recovered smoothly except for transient facial nerve palsy.
Keywords: arteriovenous malformation, vascular anomalies, CT angiogram.

Social Media and Body Dysmorphic Disorder (BDD): Is There Any Link?
Authors: Khan Wajiha , Yumna Zafar  , Maryam Khalid
Published: April 2022

To the Editor,
Body Dysmorphic Disorder (BDD) is defined as a persistent and intrusive preoccupation with a non-existent or slight imperfection in one’s appearance. Being labelled as one of the obsessive-compulsive and related disorders, it has multifactorial etiology like cognitive deficits, psychological impairment and neurochemical abnormalities.
However, a 2020 study has shed light on a  more serious concern- it showed that the use of social media for longer duration, especially Snapchat and Instagram, are associated with increased incidence of BDD distinctly in young participants.1 Other researches have also highlighted this that social media can kindle the negative belief of body image by circulating photos, videos and comments about ideal self-image triggering  insecurities especially in youngsters, about their physical features, body shape,  complexion etc.2,3  Furthermore, social media platforms like Snapchat and Instagram are specialized in photo and video editing features, a behavior that is common in people with BDD.4 Fantasizing the celebrity ideals and social media influencers has promoted body dissatisfaction, disordered eating and other psychological comorbidities resulting in more frequent dermatological and psychiatric consultations.1
According to WHO approximately 24 million people in Pakistan need psychiatric assistance. Mental illness and psychological disorders still face persistent social taboo here. As only one psychiatrist is present for every 10,000 people in the country, BDD can become a big problem for the already feeble health system here by increasing the burden of mental illnesses. People here already consider white complexion the epitome of beauty and success, and promotion of similar mentality through social media either by celebrities or by influencers can be disastrous for the mental health of young individuals. That is why it is mandatory to dictate the proper and constructive use of social media. Facebook and Twitter trends can be set up for awareness and encouraging natural beauty instead of perfectly filtered dummy faces. As celebrities and influencers are followed by many, social media sites should promote people because of their intellect, talent and hard work rather than their appearances. These trivial steps can play a pivotal role in decreasing body dissatisfaction and concerns.
Aduhelm's accelerated approval for the treatment of Alzheimer's Disease
Authors: Ellahi Buksh Aayat , Shaikh Fahd , Mankani Hasnain
Published: April 2022

Madam, despite the life-threatening manifestations that Alzheimer's disease (AD) possesses, to date, only five medical treatments have been approved for AD, which involve two classes of drugs that merely control the symptoms rather than altering the course of the disease. Moreover, in the last decade, relatively few clinical trials have been undertaken in AD, which have had a 99.6% failure rate.1 However, the United States Food and Drug Administration recently approved a drug, Aduhelm, a monoclonal antibody that directly targets the fundamental pathophysiology of the disease.2
With the advancing health care system, life expectancy in Pakistan has increased from 65.41 to 67.48 years in the past ten years, consequently raising diseases in the elderly population, such as AD.3 In efforts to find a treatment for AD, researchers carried out three trials that enrolled approximately three thousand patients who were given Aduhelm in a randomized, placebo-controlled study of different dosages. The patients who received Aduhelm showed reduced prevalence and impact of the manifestations of AD.2
The “amyloid cascade hypothesis” suggests that the accumulation of the beta-amyloid plaques results from an imbalance between the plaque accumulation and clearance in the brain, which is the main cause of AD pathogenesis. Designed specifically in keeping with the above fact, Aduhelm selectively targets and clears aggregated forms of beta-amyloid plaques, including soluble oligomers and insoluble fibrils, thus promoting healthy brain aging.4
We want to draw the attention of the readers towards the alarming number of patients being diagnosed with AD and the importance of the role of this drug in managing the manifestations of this disease. This drug has been approved for everyone with AD but it is not yet available.5 Pakistan is a developing country and unfortunately, due to economic constraints, an expensive drug like Aduhelm is an unlikely choice, a situation that leaves very few viable options. However, to reduce the inequity in the accessibility of this drug, the government could make a review in policies to subsidize the price of the drug and make it more affordable and accessible to the masses.

Joining the Anti-Brand Communities on the Internet: Who and Why
Authors: Brandão Amélia , Popoli Paolo , Passos Tomás Inês
Published: April 2022

This paper aimed to empirically deepen our understanding of the growing phenomenon of negative consumer-brand relationships in the Internet, striving to investigate “who and why” consumers join anti-brand communities against the top ten global brands. In particular, this study aims to investigate whether the consumers’ profile affects whether they develop negative feelings or not, and the main reasons for their negative feelings. Methodologically, this study is based on the quantitative methodology of the survey and on the statistical verification of several research hypotheses formulated on the impact of the main consumer characteristics (gender, age, country of origin, education, empathy) on their behavior towards the hated brands. Regarding “who”, our findings show that gender, age and country of origin are the main consumer characteristics affecting both their negative feelings towards brands and their willingness to join an anti-brand community. Regarding “why”, low quality of products/services and a lack of corporate social responsibility are the main reasons for hating brands. Finally, this study contributes to knowledge of negative consumer-brand relationships in the Internet domain and provides advanced insights into consumer behavior with reference to the top global brands. It also encourages further research on the interconnections among the central questions of this paper, i.e., who and why individuals join anti-brand communities, and represents a starting point for further studies aimed at expanding the consumer characteristics investigated in this paper, including personality traits. This study also pioneers the profile of anti-brand community participants in the Internet, which is so pertinent in the rise of marketing 5.0.

Published: April 2022

The past two decades have witnessed a high national importance to financial inclusion around the world. This paper intends to explore the impact of financial inclusion on poverty reduction and income inequality in the world, high, middle, and low-income countries. For this purpose, a new composite financial inclusion was constructed with three dimensions for finding various macroeconomic variables affecting the level of financial inclusion for 122 economies, including 32 from high-income, 38 from upper middle income, 38 from lower middle income, and 14 from low-income countries. Then the impact of financial inclusion, on poverty and income inequality, for the world and then for high, middle, and low-income countries was investigated. The estimates reveal that rule of law significantly affects financial inclusion for the world, high, middle, and low-income countries. But age dependency ratio influences the financial inclusion only for our full sample. However, population density significantly decreases financial inclusion just in the full sample and Upper middle-income countries. Education completion impacts significantly financial inclusion just in upper middle income. While literacy has a higher impact on financial inclusion in high-income countries. The findings also indicate that financial inclusion is significantly correlated with lower poverty for the full sample. The link between financial inclusion and income inequality has been found for high-income countries and lower-middle-income countries.

Authors: THANOON Karam H. , MAHMOOD Basim , DABDAWB Marwah M. A.
Published: April 2022

Recent years have witnessed a great revolution in web technologies and their applications. Most of these applications are connected to the Internet. One of the most frequent issues in these applications is the security issue. Malware is the main reason behind this issue since they harm users in many different aspects such as damaging files, stealing credentials, operating system malfunctioning, etc. Therefore, many companies around the world develop antiviruses software aiming to mitigate the security issue. Most of the known viruses can access users’ computers or web accounts through some APIs. Therefore, antivirus companies try to update the API databases of their software periodically. This paper suggests a method for investigating the relations among different kinds of malware in terms of the API they used. Then, it provides recommendations about this malware and its APIs. The method followed in this work is based on concepts inspired by network science. The malware and its APIs are modeled as a network with nodes and edges. The results show interesting facts about the investigated malware that are of interest for software security architects and give the relations between various malware which call the same API function, depending on that malicious software behavior can be detected by antivirus or anti-malware engine.

Published: April 2022

In this paper, we define uniformities and topologies as relators and show the equivalences of these definitions with the classical ones. For this, we summarize the essential properties of relators, using their theory from earlier works of Á. Száz.Moreover, we prove implications between important topological properties of relators and disprove others. Finally, we show that our earlier analogous definition [G. Pataki, Investigation of proximal spaces using relators, Axioms 10, no. 3 (2021): 143.] for uniformly and proximally filtered property is equivalent to the topological one.At the end of this paper, uniformities and topologies are defined in the same way. This will give us new possibilities to compare these and other topological structures.
El poder en ausencia. Iconografía fantasma de Felipe VI
Authors: Prat Altimira Ignasi
Published: April 2022

A pesar de que a lo largo de la historia ha sido una constante la manifestación de tipo  de formas de rechazo hacia la imagen del jefe del estado en el territorio catalán, el aumento de la tensión política entre Cataluña y el estado español a partir del año 2012, ha dado lugar a un aumento del fenómeno iconoclasta. Las imágenes que integran el presente ensayo visual son el resultado de una actividad de arqueología de la imagen, que da cuenta del fenómeno iconoclasta anti borbónico que tiene lugar en los salones de plenos de Cataluña. Concretamente el artículo pone el foco en el registro de las huellas producto de la retirada del retrato oficial de Felipe VI. Esta forma de iconoclasia simbólica o indirecta se basa en el propósito de dañar, mediante el desplazamiento o la ocultación de la imagen, el principio de integridad de una obra de arte que ha sido concebida específicamente para un contexto de oficialidad. Los indicios de una antigua presencia en las imágenes invocan una iconografía ausente y se constituyen como agentes expresivos de las tensiones políticas del momento.

Published: April 2022

La visión artificial está cobrando cada día más auge en el mundo de la robótica industrial, ya que es necesario realizar tareas cada vez más precisas y autónomas, por lo que se necesita un posicionamiento del robot más exacto. Para ello se precisa del apoyo de un sistema de visión que sea el que preste al robot precisión en su pose, calibrando dicho sistema con respecto al robot. Este trabajo presenta una metodología sencilla para abordar esta forma de calibración, llamada ojo a mano, empleando una cámara 3D de luz estructurada que obtiene la información del mundo real y un brazo robótico industrial de seis ejes. Esto permite utilizar el algoritmo RANSAC para la determinación de los planos, cuya intersección nos da las coordenadas de los puntos,lo que supone una reducción notable de los errores, ya que las coordenadas proceden de planos ajustados a miles de puntos, lo cual hace que el sistema sea más robusto y capaz de obtener una matriz de transformación de las coordenadas de la cámara a la base del robot, que le permitirá abordar cualquier tarea que precise con una precisión eficiente. Se ha realizado el análisis de errores resultante utilizando dos cámaras 3D diferentes: una básica (Kinect 360) y otra industrial (Zivid ONE+ M).

Published: April 2022

Este trabajo propone un nuevo funcionamiento en modo tolerante a fallas aplicado a convertidores CC-CC con Puentes Duales Activos Trifasicos (CPDA3) cuando ocurre una falla de circuito abierto de transistor en el puente del lado de la carga. La propuesta consiste en modificar las senales de activación de los transistores, para lograr mantener la transferencia de potencia dentro de determinados limites despues de la reconfiguración. Este enfoque no introduce costos computacionales adicionales y no requiere la incorporacion de componentes o circuitos adicionales a la topología original. La potencia maxima que se puede transferir es mayor comparado conlas propuestas anteriores. Ademas, la ondulación de la tensión de salida se reduce significativamente, lo que permite aumentar la vida util esperada de los capacitores del filtro. Se presentan los resultados de la simulación y experimentales de un prototipo de 1.5 kW para validar el analisis teórico y la viabilidad de la propuesta.

En este artí­culo se evalua el desempeño por apuntamiento de una serie de estrategias de control para seguidores solares de alta concentracion. Dado el alto grado de precisión que se necesita en el apuntamiento real, por debajo del semi ángulo de aceptancia global del sistema de captacion de energí­a, en el artí­culo se revisan las incertidumbres mas caracterí­sticas del montaje de un seguidor solar, y se establece un marco teorico que permite representar imperfecciones de montaje en forma de relaciones de rotación de marcos de referencias asociados a los elementos del seguidor. Se expone un proceso de calibracion del sistema en dos etapas, que permite estimar incertidumbres parametricas de las rotaciones. Finalmente, se analizan cinco estrategias de control y los resultados experimentales obtenidos con ellas al implementarlas sobre un seguidor solar HCPV industrial de altas prestaciones. Los resultados muestran que con el sistema bien calibrado, todas las estrategias proporcionan un desempeno similar. Sin embargo, solo la basada en realimentacion en potencia es suficientemente robusta como para proporcionar buen desempeño cuando el sistema de descalibra.

Authors: Carvalho Izabella Regina Almeida Santos de , Montenegro Silvana
Published: April 2022

El presente estudio se atuvo a discurrir sobre los conceptos de enseñanza y aprendizaje y a traer elementos de reflexión acerca de los métodos de enseñanza, considerados como resultados del desdoblamiento del pensamiento acerca de la educación y del proceso enseñanza aprendizaje. Se quiso demonstrar por medio de una revisión bibliográfica basada en la literatura pertinente, que los diversos métodos de enseñanza planteados a lo largo de la historia de la educación han sido, bien como lo son actualmente, intentos docentes de lograr el éxito educacional o promover el aprendizaje. Por último, pero sin menos importancia, se quiso reunir los fundamentos de varios métodos, en especial aquellos contemporáneos a la idea de valorar la participación del alumnado en el proceso de aprendizaje, y de este modo, constituir material de referencia para los docentes que tienen por deseo innovar en sus intentos de cultivar el aprendizaje.
RESILIÊNCIA E COPING EM CASAIS DE FAMÍLIAS EM CONTEXTO DE RISCO. UMA PERSPECTIVA DO MODELO SALUTOGÊNICA
Authors: Correia Correia Hermenegildo
Published: April 2022

A resiliência tem sido reconhecida como um processo comum e presente no desenvolvimento de qualquer ser humano (MASTEN, 2001). Contudo, faz-se necessária uma análise ecológica, a fim de investigar a maneira como as pessoas percebem e enfrentam as adversidades decorrentes dos processos proximais, bem como a influência do contexto e do tempo em que estão vivendo (CECCONELLO, 2003). Este artigo procura analisar a resiliência em casais de famílias afetadas por desastres naturais em Moçambique, dentro de um contexto de vulnerabilidade decorrente dos efeitos do desastre natural, IDAI, ocorrido em Março de 2019. A abordagem é qualitativa, assente na revisão bibliográfica de literaturas do tema em estudo. As fontes de investigação são: Google Académico; Libgen; Mendeley Reference Maneger e Scielo. O estudo incide em casais da comunidade de Savane, distrito de Dondo, Província de Sofala, região centro de Moçambique. Assume-se no estudo que as mudanças climáticas são consideradas o maior e mais complexo desafio da contemporaneidade, sendo as mesmas traduzidas em projeções científicas que delineiam cenários de grande impacto para todas as formas de vida na terra (IPCC, 2018). Moçambique é considerado um país propenso aos desastres naturais, devido a sua localização geográfica. Toma-se a abordagem sistémica para explicar a resiliência e coping em casais, a relação que se estabelece entre os elementos da família e o contexto, partindo da explicação dos vários cenários em que os casais atravessam os momentos de desastres naturais e que são levadas para os centros de reassentamento “transição ecológica”, de certa forma não tendo privacidade e são obrigadas a viver em condições precárias. Conclui-se que essa conceituação não faz referência ao impacto da família no indivíduo, mas, encara a família como uma unidade coletiva cujos resultados também são de interesse da mesma.
