Comparative analysis of Saudi sharia compliant banks: A CAMEL framework
Authors: Naushad Mohammad
Published: March 2021

A vibrant banking sector remains instrumental to the stability of every economy. Islamic banks are now considered as iris spuria of the banking industry. Countries such as Saudi Arabia have been hailed as the Islamic banking basin. Nevertheless, how well is this sector growing and performing in Saudi Arabia itself? This motivates us to carry out this study. The current study's key objective was to measure Sharia-compliant banks' efficiency on the CAMEL Framework, a commonly accepted framework for banks' financial health. CAMEL is fundamentally an acronym for which the first letter from the five primary segments of a bank operation is jumbled, i.e. “|C|apital adequacy, |A|sset quality, |M|anagement quality, |E|arnings ability and |L|iquidity”. The system is popularly being used for determining the financial soundness and stability of banks. The current study employs this framework to judge the financial performance of four fully Sharia compliant banks or Islamic banks in Saudi Arabia. The publicly accessible audited data of these banks over ten years was taken for analysis. From the final results of the analysis, it is found that all the banks performed stupendously well on the CAMEL framework. AlRajhi Bank was rated number one of all four Sharia-compliant banks. However other three banks namely Alinma Bank, AlBilad Bank, and Aljazeera bank have also done well and overachieved all the criterion of CAMEL's ranking. However, the study proposes a comparison of Sharia-compliant banks with conventional commercial banks. Moreover, it recommended that more banks should engage in offerings of Sharia based products.

Innovative policy and regional management leverages should create the foundations for the “impulse” to form the Ukrainian market of natural gas and its distribution. Efficient and desirable economic reforms in the activity of the gas distribution companies of the Western region of Ukraine will contribute to increasing their competitiveness level by implementing innovative activities. The paper aims to make an integral estimation of the competitive positions of the gas distribution companies that function on the Western Ukrainian market of natural gas distribution among consumers and develop practical recommendations directed at forming and implementing the innovative policy of improving their competitiveness. To achieve the aim, the authors have developed the methodology of calculating the competitiveness level for the gas distribution companies that function on a certain natural gas distribution market of any scale. Based on the results of the conducted research, the paper shows that the competitiveness condition of most gas distribution companies of the Western region of Ukraine is either of critical – І or satisfactory – ІІ levels. Meanwhile, it is worth mentioning that only AT “Chernivtsihaz” is characterized by the highest rate of competitiveness integral estimation among all the companies operating on the market of the natural gas distribution among consumers in the Western region of Ukraine. Therefore, it was identified as level ІІІ – “decent” level, which is the average competitive indicator.

Estratégias de intervenção, no âmbito da educação alimentar e nutricional, podem contribuir para melhoria do padrão de consumo alimentar e estado nutricional de mulheres no climatério, resultando em benefícios a saúde e qualidade de vida. O objetivo do estudo foi avaliar o impacto de uma intervenção nutricional com 2 meses de duração, baseada em estratégias de educação alimentar e nutricional, no estado nutricional, risco cardiovascular, sintomas do climatério, consumo alimentar e no estilo de vida de mulheres adultas. Trata-se de um estudo quase experimental. Coletaram-se dados, pré e pós intervenção, relacionados ao estado nutricional (peso, altura, índice de massa corporal (IMC) e circunferência da cintura (CC)), estilo de vida, satisfação e padrão de peso corporal e frequência de consumo alimentar. Os sintomas do climatério foram avaliados através do Menopause Rating Scale (MRS). Os dados foram analisados no Programa Statistical Package for Social Science (SPSS). Totalizaram-se 16 mulheres, com idade média 54±5,24 anos, sendo que 62,5% referiram aumento do peso nos últimos anos, e 75% manifestaram insatisfação corporal. Houve redução significativa da CC (p=0,006) e da classificação do IMC (p=0,046), do pré para o pós intervenção. Verificou-se aumento na frequência de ingestão de produtos lácteos, ovos, feijão, grãos, e redução do pão branco. Quanto ao estilo de vida e sintomas de climatério, não foram observadas mudanças significativas. A intervenção nutricional com 2 meses de duração mostrou impacto positivo em hábitos de consumo alimentar e estado nutricional de mulheres em fase de climatério.
Overdenture retida por implante único: Uma alternativa para a reabilitação oral de idosos
Authors: Hauck Kassia , Sacker Thamiris Nogueira , Freitas Valquiria De Jesus , De Carli João Paulo , Trentin Micheline Sandini
Published: March 2021

Com o aumento da expectativa de vida, houve também o aumento da procura dos pacientes edêntulos por uma forma reabilitadora que lhes proporcione maior eficiência mastigatória. Sendo assim, as sobredentaduras sobre implantes utilizando sistemas de encaixe representam modalidade protética mucossuportada e implantorretida que possibilita maior segurança, estabilidade e estética, além de apresentarem menor custo e facilidade para higienização. Internacionalmente, dois implantes são considerados adequados para manter uma overdenture nas mandíbulas desdentadas. No entanto, para muitos pacientes a instalação de dois implantes pode representar um procedimento invasivo e oneroso. Por meio do relato de um caso clínico e da literatura consultada, o presente trabalho mostra que a inserção de um único implante na porção central da mandíbula pode estabilizar a prótese total e melhorar a qualidade de vida e a função mastigatória da saúde bucal. Paciente masculino, 65 anos de idade, relatava falta de estabilidade da prótese total inferior convencional, confeccionada há vários anos. O tratamento proposto foi a instalação de implante único em sínfise mandibular e posterior confecção de novas próteses totais. Uma fixação com pilar tipo o’ring e matriz ativada por parafuso foi usada para manter a sobredentadura inferior. Os resultados clínicos iniciais são promissores, sendo que o paciente do caso em questão relata melhoria na mastigação, estabilidade e função da prótese retida por implante único. No entanto, antes que esse método possa ser recomendado para aplicação clínica geral, são necessários resultados de estudos clínicos longitudinais.

Throughout the recent two decades the issue whether architecture is still at its core a public art and whether construction in the public zone in all forms there of still remains the main purpose of architectural practice has been questioned. Given the crisis that has attended architectural language the last half of the 20th century, we have to acknowledge that one of the most difficult issues facing architects today is the way in which a public building is still able to express certain intrinsic values as these are embodied in (1) volumetric organisation, (2) structural order, and (3) representational form [2].The subject of this article is the presentation and analysis of author’s concept of the Copernicus Science Centre in Warsaw in terms of both formal and functional solutions - design as a reciprocal act and serving as models for ecological architecture. In course of the conducted studies various features required for proper functioning of a contemporary public building have been identified. These include: relations of the enclosure to internal space, spatial organisation, frontiers be-tween the interior and surroundings, and relations between the building and the landscape.

A KNIGHT IN THE SERVICE OF ART.
HANNA BENESZ IN MEMORIAM (1947–2019)
Authors: Romanowska-Zadrożna Maria
Published: March 2021

Hanna Benesz graduated from the Institutes:
of Art History and of Applied Linguistics at the University
of Warsaw. Her whole career launched in 1975 remained
inseparably connected with the National Museum in
Warsaw, where she worked at the Gallery of European
Art curating the Flemish and Dutch collections. She
followed all the promotion steps: from assistant to curator.
Benesz strongly believed that museum curator’s job was
grounded in a perfect knowledge of the collection. Thanks
to her research conducted into the paintings amassed in
National Museum’s storerooms, she successfully attributed
a substantial number of works and identified provenance of
many. She studied iconography applying research methods
worked out by iconology. Moreover, she focused on the
paintings’ technical condition, this occasionally leading to
spectacular ‘restorations’, e.g. the identification of a genuine
work by Abraham Janssens (ca 1575–1632) the Lamentation
of Christ in a forgotten work, previously considered to be
a copy. Author and co-author of many exhibitions, she
cooperated with museum curators around the world. Her
exhibition on Baroque art reached as far as Japan. Benesz’s
intention was not only to present the paintings from the
National Museum’s collections through a direct contact of
visitors with the works, but also in publications, mainly in
English and online. As soon as she became curator, together
with Maria Kluk she focused on working out the reasoned
catalogue Early Netherlandish, Dutch, Flemish and Belgian
Paintings 1494–1983 in the Collections of the National
Museum in Warsaw and the Palace at Nieborów. Complete
Illustrated Summary Catalogue, published in 2016. A year
later, the Catalogue was honoured with the main prize in the
Sybilla Competition in the category for publications, while
the King of the Netherlands awarded Hanna Benesz with
the chivalric Order of Orange-Nassau (Oranje-Nassau) of the
5th grade; she was decorated with it by the Ambassador of
the Kingdom of the Netherlands during the 20th CODART
Congress held at the Warsaw Łazienki Palace.
Not only was Hanna Benesz an outstanding museum curator
and scholar, but also a trusted friend and a warm empathetic
person, sensitive to other people’s misfortunes.

Gatos virtuais: detectando e avaliando os impactos da mineração de criptomoedas em infraestrutura pública
Authors: Pires Victor , Coutinho Felipe , Menasché Daniel , De Farias Claudio
Published: March 2021

Blockchains e criptomoedas representam uma forma revolucionária de converter energia em meio de troca. Atualmente, vislumbram-se inúmeras aplicações para blockchains e criptomoedas, para ﬁns que variam desde o controle de inventário até aplicações bancárias. Naturalmente, para se minerar de forma economicamente viável buscam-se regiões nas quais a energia seja abundante e barata, e.g., próximas a usinas hidroelétricas ou em determinados países onde a produção de energia é maior que a demanda. A possibilidade de conversão de energia em dinheiro, no entanto, também abre oportunidades para um novo tipo de ataque cibernético que visa a mineração de criptomoedas. Nesse trabalho, usando dados de janeiro e fevereiro de 2018 da Universidade Federal do Rio de Janeiro UFRJ, observou-se que tal ameaça é real e apresenta-se uma projeção dos custos e ganhos derivados desses ataque. Indica-se também formas de detecção e mitigação desses ataques que foram implementadas com sucesso na UFRJ.
Filtro de Bloom como Ferramenta de Apoio a Detectores de Ataques Web baseados em Aprendizagem de Máquina
Authors: Rego Richard Caio , Nunes Raul
Published: March 2021

Ataques contra aplicações da Web implicam em prejuízos sociais e ﬁnanceiros. Os sistemas de detecção atuais que utilizam técnicas de aprendizagem de máquina não são escaláveis o suﬁciente para lidar com grandes volumes de dados. O Filtro de Bloom é uma estrutura de dados aleatória simples e eﬁciente que permite testar se um determinado elemento pertence a um conjunto de forma probabilística. Neste artigo aplicou-se o Filtro de Bloom combinado com sete técnicas de aprendizagem de máquina comumente utilizadas em detectores de anomalias para ataques web. Os resultados demonstram que o uso do ﬁltro como primeiro estágio do mecanismo de detecção de anomalias reduz tanto o tempo médio quanto o tempo total de detecção em todas as técnicas. Os resultados também demonstram que o ﬁltro pode auxiliar inclusive a incrementar a acurácia e a precisão, se adotada a otimização proposta na conﬁguração do Filtro de Bloom para redução de falsos negativos.

Authors: Colomé Marcelo , Nunes Raul , Silva Luis Alvaro
Published: March 2021

Este trabalho explora a aplicação de técnicas computacionais para a gestão do conhecimento de incidentes de segurança, oferecendo uma abordagem metodológica para a retenção e reutilização do conhecimento do especialista, visando a resolução de novos incidentes. O conhecimento do especialista em segurança da informação é fundamental para as organizações, pois a resolução eficaz de incidentes de segurança depende do conhecimento dos mesmos. Porém, as organizações não devem ser totalmente dependentes de seus funcionários. Desta forma, a metodologia proposta utiliza-se de Raciocínio Baseado em Casos com ponderação dos atributos sobre dados representados no padrão IODEF, visando a retenção do conhecimento do especialista na resolução de incidentes, possibilitando que outros membros da organização possam desempenhar tarefas similares, diminuindo a dependência de empresas de segurança em relação a seus funcionários. Os resultados demonstram que através desta metodologia o conhecimento fica efetivamente retido na base de casos e que novos funcionários podem se beneficiar de recomendações construídas e fornecidas pelo sistema, melhorando com isto a retenção do conhecimento nas organizações. 1

Authors: Rampelotto Junior Charles , Quincozes Silvio , Kazienko Juliano
Published: March 2021

A Internet das Coisas (IoT) tem ganhado elevado destaque no âmbito das tecnologias emergentes. Nesse cenário, um problema de segurança relevante que carece de estudos consiste na personiﬁcação de dispositivos. Este trabalho propõe um mecanismo, chamado LegitimateBroker, a ﬁm de mitigar ataques de personiﬁcação em um dispositivo Broker MQTT na IoT. A proposta fundamenta-se na autenticação mútua entre Publicadores e Broker, armazenamento indireto de chaves no Broker e renovação periódica de chaves no Broker e no Publicador. Experimentos indicam que o mecanismo proposto tem baixa sobrecarga comparado a outras abordagens e pode ser facilmente parametrizado a ﬁm de que a taxa de renovação de chaves se adéque a periodicidade de publicações realizadas pelos nós da rede e ao tempo de efetivação do ataque.

Published: March 2021

O crescimento da IoT vem possibilitando a criação de serviços cada vez mais personalizados, entre eles destacam-se os serviços industriais que muitas vezes lidam com massiva quantidade de dados. Porém à medida que a IoT cresce as suas ameaças são ainda maiores. Entre as ameaças estão os ataques de injeção de dados falsos (IDF) que se destacam por serem um dos mais agressivos às redes de dados como a IoT. Embora existam mecanismos que lidam com essa ameaça, eles não consideram a validação dos dados, principalmente sobre o serviço de agrupamento de dados. Este trabalho propõe um mecanismo de detecção de intrusão contra ataques IDF, chamado CONFINIT, sobre o serviço de disseminação de dados em IoT densa. Ele combina estratégias de vigilância watchdog e consenso colaborativo para a detecção de atacantes, garantindo a autenticidade dos dados coletados pelos dispositivos. O CONFINIT foi avaliado no NS-3 e obteve 99% de taxa de detecção, 3,2% de falsos negativos e 3,6% de falsos positivos, e aumentou em até 30% os agrupamentos sem ataques IDF.

Published: March 2021

Computer authentication systems based on login and password have been vulnerable to the action of unauthorized users. Currently, authentication techniques based on behavioral models predominantly use information extracted from mouse and/or keyboard to authenticate users. Operating system performance indicators can be used as an alternative. This work proposes an approach using data from performance indicators such as source data, CNN/LSTM networks for data classification, and reliability-based assessment methodology for the purpose of authenticating the user on an ongoing basis. The results obtained demonstrate the feasibility of using these attributes as the origin of the data to define a behavioral model. The best result obtained in this research is that 100% of genuine users are never inadvertently blocked and 100% of the imposters are detected after the average of three actions. Sistemas de autenticação de computadores baseados em credencias de contas (e.g. login e senha) têm sido vulneráveis à ação de usuários não autorizados. Atualmente, as técnicas de autenticação baseadas em modelos comportamentais predominantemente usam informações extraídas de mouse e/ou teclado para autenticar os usuários. Contadores de desempenho de sistema operacional podem ser utilizadas como alternativa. Este trabalho propõe uma abordagem utilizando dados de contadores de desempenho como dados de origem, redes CNN/LSTM para classificação dos dados e metodologia de avaliação baseada em nível de confiança com o propósito de autenticar o usuário de forma contínua. Os resultados obtidos demonstram a viabilidade do uso destes atributos como origem dos dados para definição de modelo comportamental. O melhor resultado obtido nesta pesquisa é que 100% dos usuários genuínos nunca são bloqueados inadvertidamente e 100% dos impostores são detectados após a média de três ações.

Authors: Martins Diego , Henriques Marco Aurélio
Published: March 2021

Este artigo apresenta uma análise preliminar do mecanismo de consenso para blockchains baseado em Proof-of-Stake com Tempo Discreto (PoSTD). O texto explica os mecanismos que controlam a criação de novos blocos e a eliminação de forks na cadeia. Em seguida, o mecanismo de consenso é analisado de forma genérica, através de diferentes cenários na visão de um determinado nó. É mostrado como o algoritmo atinge o consenso mesmo com atrasos na rede, desde que o tempo de duração de uma rodada de trabalho seja superior ao maior dos atrasos de comunicação entre dois nós quaisquer conectados no sistema.

Published: March 2021

In this work composite structures based on a porous silicon were obtained and studied. Porous matrices were formed by electrochemical etching in aqueous solutions of hydrofluoric acid. Based on the obtained substrates, por-silicon (Si)/silver (Ag) and por-Si/zinc oxide (ZnO) composite structures were formed. These composites were functionalized by various methods (electro (E)-, thermo (T)-, electrothermal exposure) as a result of which the structures were modified. When studying the samples by scanning electron microscopy (SEM), it was concluded that silver nanoparticles actively diffused into the pores under these technological modes of functionalization. The por-Si/Ag and por-Si/ZnO composite structures were also studied using the following methods: infrared (IR) spectroscopy and Raman ultrasoft X-ray emission spectroscopy. Also, the photoluminescent characteristics of the samples were studied. Based on the obtained results, it was concluded that functionalization methods actively change the phase composition of structures and the optical properties of composites.

Published: March 2021

Background: Oral squamous cell carcinoma (OSCC) is the most common malignancy of the oral cavity and oral lichen planus (OLP) is considered a premalignant disease. Objectives: This study aims at comparing the salivary levels of lactate dehydrogenase (LDH), C-reactive protein (CRP), and cancer antigen 125 (CA125) among cases with OSCC, OLP, and healthy persons. Methods: In this case-control study, salivary markers were evaluated in 55 cases (15 patients with OSCC, 20 patients with OLP, and 20 healthy persons); non-stimulated saliva samples were collected from the patients and saliva markers were measured by the enzyme-linked immunosorbent assay (ELISA) method. The data were analyzed, using SPSS 21 software and ANOVA test and P < 0.05 was regarded as significant. Results: Salivary LDH and CA125 levels were significantly higher in OSCC and OLP patients compared to the control group (P < 0.05). Salivary CRP levels were significantly higher in OSCC patients compared to OLP patients (P < 0.05). Besides, salivary CRP levels were higher in OLP subjects than in the control group, but the difference was not significant (P = 0.56). Conclusions: The identification of the salivary LDH, CA125, and CRP may provide a suitable non-invasive predictive tool for malignant changes. However, its use in clinical practice needs further research.

Background: Von Hippel Lindau (VHL) disease is a hereditary disorder characterized by the development of benign or malignant tumors in the brain, spinal cord, eyes, adrenal medulla, kidney, pancreas, and many other organs. Advances in molecular diagnosis have led to the identification of the affected members of families at earlier stages. We present the clinical, laboratory, and genetic characteristics of five generations of a large Iranian kindred with VHL. Methods: The proband, a 52-year-old Iranian man, was recognized with VHL. All family members underwent clinical, laboratory, imaging, and genetic evaluation. Medical files and histopathology reports of patients who had been operated on before were also reviewed. Diagnosis of the disease was based on clinical findings, positive family history of VHL, and development of a central nervous system or retinal hemangioblastoma or pheochromocytoma. Results: Based on diagnostic criteria, our initial evaluations revealed that 10 members of the family had already been affected by the disease. Among them, nine had pheochromocytoma, and one had retinal hemangioblastoma. There was no case of kidney tumors among the kindred. Conclusions: Study results show the high penetrance of the disease and focus on the large burden imposed by the disease on the health and quality of life of patients afflicted with the disease, emphasizing the importance of surveillance from early childhood for detection and management of the disease as early as possible.
