O tabagismo e o risco de recorrência de acidente vascular cerebral: revisão da literatura
Authors: De Queiroz Aguiar Vinícius , Vilhena de Castro Souza Fabrício , Rodrigues de Camargo Renan , César Meyer Júlio
Published: April 2024

O tabagismo está entre as principais causas preveníveis de morte no mundo e a mortalidade geral em fumantes é três vezes maior do que em não fumantes. Aproximadamente um quarto da população mundial é tabagista, sendo que 80% dessa população está em países subdesenvolvidos ou em desenvolvimento. O tabagismo é um fator de risco independente para o acidente vascular cerebral (AVC), com risco de duas a quatro vezes maior de desenvolver um episódio do que na população não tabagista. A cessação do tabagismo após uma síndrome coronariana aguda (SCA) é associada a um menor risco de recorrência de eventos vasculares e mortalidade. Em pacientes que sofreram um AVC, a relação entre o status tabágico e a recorrência de um novo AVC ainda não está definida. Dessa forma, o objetivo do estudo foi avaliar a associação entre o tabagismo e a recorrência de AVC após um primeiro episódio. Foi realizada uma revisão da literatura a partir de artigos publicados até março de 2023 nas plataformas MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (Cochrane) e Scopus (Elsevier). A manutenção do hábito de tabagismo após um evento inicial de AVC foi associada a um maior risco de desenvolver um segundo episódio de AVC nos três estudos. Os pacientes que se mantiveram tabagistas demonstraram um maior risco para a recorrência do AVC quando comparado aos que nunca fumaram. De forma semelhante aos estudos sobre recorrência em SCA, os pacientes que interromperam o uso de cigarro logo após o evento inicial ou até 6 meses depois, não apresentaram diferença significativa do risco de recorrência comparado aos pacientes que nunca foram tabagistas. O risco de recorrência de AVC é dose dependente, com o risco podendo ser duas vezes maior a partir de 20 cigarros fumados por dia comparado com os não tabagistas. A cessação do tabagismo parece estar relacionada a um menor risco de recorrência de AVC, mostrando-se como uma oportunidade para atuação médica desde o hospital até o acompanhamento futuro do paciente.

Authors: Mohit Kumar  , Ayush Kumar Choudhary  , Dr. Angshuman Mandal
Published: April 2024

A truss is a collection of axially loaded structural elements connected through pin joints. Optimization of truss structures indicates the determination of best possible conditions that are necessary for achieving the most economical design in terms of lowest possible weights of the truss elements. According to recent studies, Size, Topology and Shape based optimizations are the three possible independent optimization scopes for finding the optimum weight of a truss. The current study focuses on the size optimization of truss structure and aims to identify the most cost-effective sections of the truss using a powerful evolutionary optimization technique named as Genetic Algorithm (GA). Here single point cross over method and bit wise mutation operator are adopted for expanding the search space with the assigned displacement and stress constraints. Fortran based sub routines are developed for each individual steps of GA such as fitness evaluation, selection, cross-over and mutation. Finaly the complete program is run for validation of its outcome. While comparing with the solution of an existing literature regarding a minimization of objective function having two design variables the outcomes tend to show a good correlation. Further, the study is extended for the weight minimization of two widely used truss having 10 members and 17 members respectively with standard Finite Element Method of analysis. Minimum weight of each truss is obtained via convergence plot and compared with the existing literatures. With this simple but efficient global optimization technique optimum weight of truss structure can easily be achieved.

Published: April 2024

The implementation of correctional revitalization is not only related to structural adjustments and security protocols at Super Maximum Security (SMAX), Maximum Security (MAX), and Medium Security (MS) correctional facilities; it may also have an impact on changes in officer-inmate interaction patterns and the psychological stress officers. After the implementation of institutional revitalization, this study intends to investigate the patterns of officer-inmate interaction and the levels of stress experienced by correctional institution personnel in Nusakambangan with various degrees of security. Eight officers were interviewed as part of the research approach, which involved descriptive qualitative analysis, in four prisons on Nusakambangan Island. The analysis's findings give an example of the many ways that SMAX, MAX, and MS prison guards and convicts engage with one another. Because of restrictions on prisoners' freedom of movement, the implementation of security measures, and disparities in treatment within the development program, different interaction patterns result. Comparing convicts in XMAX and MAX prisons to those in MS prisons, authorities believe that MS prisoners spend more time outside of their rooms engaging in activities, which could compromise security and order. The result is that because inmates in MS prisons are free to roam the facility, but inmates in SMAX and MAX prisons engage in more activities in their quarters, the stress level for officers in MS prisons is higher than the stress level in SMAX and MAX prisons.

A REVIEW ON THE β-CAROTENE: PRODUCTION, EXTRACTION, SYNTHESIS AND BIOLOGICAL PROPERTIES
Authors: Rinku Rinku , Kumar Praveen , Ahmed Shamim
Published: April 2024

The presence of double bonds gives β-carotene its distinctive hue, making it an oxygen-deficient isoprene-containing molecule. There are cyclic rings at both ends of the molecule. The present review was based on the production, extraction, synthesis and biological properties of β-carotene. Mammals can't produce carotenoids from scratch; therefore, they must get them from somewhere else. Algae, higher plants (in fruits and flowers as esters), fungi, and animals all have these yellow, red, and orange pigments in their natural forms. Carotenoids are found in human breast milk and can be modified through the mother's diet. Hexane, tetrahydrofuran, and acetone are examples of aprotic organic solvents that can be used for solvent-based extraction of -carotene from algae after and before they have been treated. The -carotene in algae, fungi, and plants can be extracted with the help of these solvents. The extraction process for -carotene is sped up and improved by the use of supercritical fluids. Increasing beta-carotene production can be accomplished by tailoring a number of environmental factors, including the type of organism used in the cultivation process, the amount of light available, the amount of salt present, the pH level, and the type and availability of carbon sources. Microalgae, plants, and fungus have all been optimised to increase their beta-carotene synthesis. It concluded that when administered in different doses, it has been shown to have effects like antioxidant and anti-inflammatory. it is also effective against cancer, cardiovascular diseases, Covid-19 and various other diseases.
Addressing the "Winner-Takes-All" Character of Sustainability Taxonomies: Towards a Scorecard Approach
Authors: Zetzsche Dirk Andreas , Bodellini Marco
Published: April 2024

Sustainability classification systems (or "taxonomies"), of which the EU environmental taxonomy is the most important, often result in a binary approach whereby best-in-class economic activities are qualified as sustainable, while all other activities are grouped together into a catch-all category irrespective of their contribution to, or potential for, contributing to and/or furthering the transition towards a sustainable economy.Such binary approaches are misleading and likely to result in under-investment in both activities crucial for the transition to net zero and innovation with the potential to support and facilitate such a pro-environment transition. Making taxonomies easy to apply, consistent, open to innovation and comprehensive at the same time is imperative if the world’s economies are to achieve net zero, even when this dilutes technical precision in the process.We argue in favour of expanding classification systems to include (information on) transition and potential transition activities, and present a scorecard approach to meet that very objective.

A cellular automata approach for extending data privacy and security of edge computing
Authors: Sharma Sandeep Kumar , Kumar Anil
Published: April 2024

This article introduces a cellular automaton (CA) based method to heighten the security breach of edge computing data. Edge computing is an innovative computing paradigm that controls the processing network’s edge devices. Relocating computation nearer to the resource is the main goal of edge computing. Based on the CA’s concept, a strong secret key is introduced for text cryptography. The secret key generated in this research is a 64-character key, which performs substitutions and reverse substitutions on the plain text and cipher text by dividing the text into blocks of 64 characters. The key may be to use the same or different letters to substitute the same letters of the plain text which makes it a unique key. The strength of the key is evaluating using the substitution speed, memory utilization, possible attack, and avalanche effects.
Some applications of trace of powers of matrices to graph theory, algebra and combinatorics
Authors: Patil Kailash M.
Published: April 2024

In this paper, using Cayley Hamilton Theorem, we exhibit a combinatorial formula for Tr(An), (n ∈ ℤ, A ∈M3 (K)), over the field K(= ℝorℂ)using Tr (A), det(A) and sum of principal minors of A. Further, a formula for ∑nk=0 Tr(Ak) is derived. For specific values of Tr(A) and det(A), the formula of Tr(An) is highly simplified. We exhibit some applications of our results in Graph Theory, Algebra and Combinatorics. We have verified our results on various matrices using Scilab and found that Scilabfails tremendously because of the truncation. But our formulae give exact result.
On the relations between antitrace, row/column sum of elements and generalized horadam sequence associated with a matrix
Authors: Sutaria Kinnari A. , Desai Narendrasinh B.
Published: April 2024

Using Cayley-Hamilton theorem for a given matrix A = [aij] ∈ M2(K), (K = ℝ or ℂ),  we obtain the recurrence relations for Tra(An), suRi(An) and suCi(An);  Tra(An+2) = Tr(A)Tra(An+1) – det(A) Tra(An) suRi(An+2) = Tr(A)suRi(An+1) – det(A)suRi(An) suCi(An+2) = Tr(A)suCi(An+1) – det(A) suCi(An)    where Tra(A) = a12 + a21  is the sum of antidiagonal entries of A and suRi(A) or scCu(A) is the ith(i = 1, 2) row or column sum of A respectively. In doing so, the analogy between the above natural recurrences and the Horadam sequence is observed. Motivated by this, we define the Horadam sequence {Wn(a, b : Tr(A), det(A))} and Fibonacci sequence {Fn = Wn (0, 1; Tr(A), det(A))} associated with A. In this paper, Tra(An), {suRi(An)}, {suCi(An)}, {Wn} and {Fn} sequences are defined and their inter-relationships are extensively studied. We also obtain Binet’s formulae, generating functions, Cassini identities, Vajda’s identities and Catalan’s identities for these sequences. Further, identities are illustrated for particular values of trace and determinant of a matrix

Chaotic map-based selective image encryption via diffusion and confusion
Authors: Paliwal Mrinal , Soni Punit , Kumar Rajender , Goyal Ankur , Malik Meena , Goyal Bhavna
Published: April 2024

Industrial diversification and Technology have a drastic impact on the day-to-day life and economic growth of the country. Sharing multimedia content over the network has drastically increased. The multimedia data can be just social media images or some highly confidential data. There is a high demand for secure image transmission over networks in the age of the Internet and other transmission mediums. Since images are high-volume data, care must be taken to ensure that the security does not become computationally very expensive. To overcome these problems, we propose a method to encrypt the images selectively using a chaos map. Selective encryption is the process of encrypting an image so that only a piece of it is visible while the remainder is encrypted. This decreases the computational cost of the algorithm to a great extent. Selective encryption consists of two parts, public and private. The public part of the image is visible to everyone but the private part is only visible to the authorized user. The chaotic map is used for encrypting the image and providing security to the algorithm. Confusion and diffusion are used for key generation using pixel value substitution and scrambling. We use PSNR, histogram analysis, and correlation coefficient to verify the result.

Security and privacy of EMI images while being transmitted over an insecure medium or when stored on third-party storage. In this paper, an enhancement of the EBS steganography with four layers of cryptography has been implemented to ensure the secrecy and privacy of a large and diverse data set of X-ray images available in JPEG format. The major objective of this research is to secure a large and diverse data set of EMI into a cover image without degrading the EMI quality as these can be used for future medical referencing. A data set of 5856 varying dimensioned and sizes X-ray images is hidden one at a time around the Edge of the normalized cover image Lena using edge-based steganography. The algorithms with various performance evaluation tests such as Computational Time is 0.135217 seconds for creating one stego-crypto-image, Peak Signal to Noise Ratio (PSNR) is 74.55838892 dB, Mean Square Error (MSE) is 3.50075E-08, Bit Error Rate (BER) is 2.25493E-05, SSIM is 0.46291047, etc. The results obtained showed less computational time, while quality tests such as BER, and SSIM ensure that the image extracted is the same as the original hence better performance and reduction in computational time.
Mitigating DDoS attacks with an intrusion detection and prevention system based on 2-player Bayesian game theory
Authors: Joshi Sagar Vasantrao , Wagh Nanda , Kumar Jambi Ratna Raja , Dongre Deepika , Rizvi Nuzhat , Bhowmik Mahua
Published: April 2024

Distributed Denial of Service (DDoS) attacks are very dangerous to the availability and security of networks, so they need improved ways to be stopped. This article suggests a new way to fight DDoS attacks that uses Intrusion Detection and Prevention Systems (IDPS) and 2-Player Bayesian Game Theory. Traditional IDPSs often have trouble responding quickly to changing attack tactics, which makes them less effective as defenses. The suggested structure, on the other hand, imagines the attacker and defense interacting as a Bayesian game. This lets them make proactive choices and come up with flexible ways to respond.The system uses Bayesian reasoning to describe the attacker’s actions and plans’ doubt, which lets it better assess the threat and decide how to respond. By constantly changing probability distributions based on what it sees attackers doing and what it sees defenders doing, the IDPS can quickly and effectively change its defenses to deal with new threats. The strategy contact between the attacker and the defense adds a competition factor that makes attackers less likely to start DDoS attacks by making them more expensive and risky. The proposed method works to stop different kinds of DDoS attacks while reducing the number of fake positives and negatives through a lot of simulations and experiments.

Published: April 2024

In a world that is becoming more and more digital, Multi-Factor Authentication (MFA) is essential for making network access safer. The purpose of this study is to suggest a way to adopt MFA that will make network systems more resistant to cyber risks and illegal access. Adding different types of authentication, like passwords, fingerprints, smart cards, and one-time codes, is the first part of the suggested approach. By making users prove their identity in more than one way, the system adds more layers of protection, making it less likely that someone will get in without permission, even if one of the factors is broken. In addition, the application stresses how important it is to have a strong method for verifying identities. This includes making sure users are who they say they are by using personal data, like fingerprints or face recognition, which are hard to fake or copy. The system also has flexible authentication features that change the amount of authentication needed based on things like the user’s position, the device they’re using, and how they usually behave. This flexible method improves the user experience by reducing the hassle of identification while still meeting high security standards. Furthermore, the application includes full logs and tracking tools to quickly find and stop any shady actions. By constantly watching tries at authentication and how users act, the system can spot possible security holes and take steps to reduce risks.

El presente trabajo tiene como objetivo ofrecer una aproximación al complejo proceso de cambio de nombre por el que pasan los individuos pertenecientes a la comunidad transgénero y la ejemplificación de este mediante los relatos onomásticos de algunos individuos transgénero españoles. El análisis de estos relatos permite el acercamiento, por un lado, desde la perspectiva de las actitudes lingüísticas, y, por otro, desde el estudio del léxico, que permite corroborar lo narrado con datos cuantificables y objetivos. Apoyándonos en los datos del Instituto Nacional de Estadística (INE), ofrecemos una caracterización de estos nombres en base a su innovación y ruptura con el repertorio antroponímico anterior, además de ratificar el papel del nombre como elemento configurador de la identidad y, por tanto, sujeto a una clara intención de hipercaracterización genérica en este proceso.

Данная работа посвящена изучению особенностей развивающего обучения в процессе познавательной деятельности в области лингвистики. В статье раскрывается содержание определения понятия «развивающее обучение», рассматриваются особенности развивающего обучения на уроках русского языка в современном школьном образовании, показана роль занимательного материала и специфика его использования в процессе развивающего обучения. Изучив труды ученых, методистов, педагогов-новаторов по этой проблеме, была выдвинута гипотеза, что развивающее обучение является важной частью процесса познания, обучения. В результате проведенного исследования было выяснено, что благодаря процессу поиска и познания достигается развитие мыслительной деятельности учащихся. Цель развивающего обучения – развитие познавательных и творческих способностей учащихся. Организация такого обучения в основном составляет поисковую, познавательную учебную деятельность ученика. Смысл активизации учащегося через развивающее обучение заключается не просто в усвоении готовых выводов науки, а в стимуляции его познавательной деятельности по самостоятельному приобретению новых знаний и способов умственной деятельности. Важной частью развития и обучения детей является формирование социальной и эмоциональной компетентности. Социальная и эмоциональная компетентность означает способность понимать и управлять эмоциями и поведением для принятия решений и достижения целей, а также для установления и поддержания позитивных отношений, в том числе и проявления сочувствия к другим. Развитие этих способностей важно для обучения и успехов детей. Ключевые слова: развивающее обучение, познавательная деятельность, зона актуального развития, учебный процесс, технологии.

Экономика промышленности находится на этапе технологического развития, ориентированного на «зеленую» трансформацию подсистем управления. Современные промышленные компании функционируют в формате платформенного взаимодействия, организуя процесс производства путем активного внедрения цифровых двойников, включая экологические приоритеты «прозрачности» сырьевых потоков, глубину переработки, «бережливое» производство. В связи с этим становятся востребованными концептуальные подходы платформенной экологизации производства. Концепции целесообразно привязать к «зеленым» инструментам, которые способны обеспечить производство и реализацию высокотехнологичной продукции, которая займет новые рыночные ниши. Такое видение обосновано стремлением производителей предугадать запросы потребителей нового поколения, которые нацелены на сохранение оптимальных параметров «эко-потребления». В качестве объекта исследования определена платформенная экологизация производства, как возможность адаптации управленческих подходов для субъектов хозяйствования, стремящихся занять лидирующие позиции на внутреннем и внешних рынках. Показано, что экологизация производства должна учитывать факторы преобразования институциональной среды, оказывающей прямое воздействие на систему ESG-трансформации. В ходе исследования выявлено, что индикаторы социально-экологического развития помогают корректировать стратегию «зеленой» экономики и экологическую политику промышленных компаний, повышая прогрессивность менеджмента предприятий, уровень инновационности организационно-управленческих структур. Ключевые слова: экономика промышленности, экологическая политика, ESG-трансформация, экологический брендинг, устойчивое развитие, «зеленая» сертификация, технологическая интеграция.

In this article, the authors analyze the specifics of women’s entrepreneurship as a separate phenomenon that is gaining momentum in the modern world. Women are increasingly striving for self-realization and economic independence, and entrepreneurship is becoming one of the strategies for achieving these goals. The purpose of this article is to analyze the main characteristics of women’s labor in Kazakhstan. The gender statistical data describing the representation of women in the Kazakhstani labor market, the level of income of women and men, the number of women managers and women entrepreneurs, and regional specifics of labor serve as a methodological tool for realizing the goal. As an additional method of analysis it is proposed to consider the results of questionnaire survey of female students of economic specialties of higher education institutions of Kazakhstan, which showed the level of girls’ preparedness for entrepreneurship. The collected data demonstrate that Kazakhstani girls do not perceive the presence of gender inequality in both the labor market and business. They do not take into account the lack of equal starting opportunities, institutional restrictions on doing business, and gender stereotypes that limit the scale of female entrepreneurship in the country. It is especially important to note that the surveyed girls are ready to combine business activities and domestic labor. They believe that such a combination is quite organic and obligatory for Kazakhstani women, and family should be a higher priority than business. The article was made within the framework of the project: Grant No. AP14871920 Keywords: female entrepreneurs, pay inequality, female executives, second shift, income levels, motherhood.
