Authors: Said Hassan , Silvester Abuodha , Mwero John Nyiro
Published: May 2023

As a result of the growing environmental concerns in the cement industry and the rising cost of building materials, alternative cement technologies have become an area of increasing interest. In this study, geopolymer concrete containing fly ash class F and bamboo leaf ash was chosen as a cement substitute in concrete manufacturing. This research was an experimental study evaluating the effect of bamboo leaf ash (BLA) on geopolymer concrete by addition as a partial replacement of fly ash. The test samples were 100 x 100 x 100 mm cubes and 300 x 150 mm cylinders at the ambient curing temperature. The design mix of C25 was used for this study. This research aimed to explore the suitability of the use of bamboo leaf ash as a mixing material in geopolymer concrete in more environmentally friendly industries. The properties that were investigated in this study are the basic aggregate tests, XRF analyses of BLA and fly ash, and workability tests by evaluating slump and compaction factor tests. In addition, compressive strength and splitting tensile strength of 28, 56, and 90 days. Therefore, in this study, various levels of bamboo leaf ash were utilized, including 0%, 5%, 10%, 15%, and 20% BLA. The alkaline liquid-to-binder ratio for all mixes was constant at 0.6, while the Na2SiO3 to NaOH ratio was 2.5. The test results of the workability show that the increased amount of bamboo leaf ash gradually reduces the alkaline liquid. The result of compressive and splitting tensile showed that fly ash substitutes that contained 5% and 10% of the bamboo leaf had higher strengths of about 38.7 MPa, 40.8 MPa, 4 MPa, and 4.22 MPa, respectively than other mixtures. Therefore, bamboo leaf ash can be one of the constituent materials used to improve the mechanical properties of geopolymer concrete

A Classification Study in High-Dimensional Data of Linear Discriminant Analysis and Regularized Discriminant Analysis
Authors: Araveeporn Autcha , Banditvilai Somsri
Published: May 2023

The objective of this work is to compare linear discriminant analysis (LDA) and regularized discriminant analysis (RDA) for classification in high-dimensional data. This dataset consists of the response variable as a binary or dichotomous variable and the explanatory as a continuous variable. The LDA and RDA methods are well-known in statistical and probabilistic learning classification. The LDA has created the decision boundary as a linear function where the covariance of two classes is equal. Then the RDA is extended from the LDA to resolve the estimated covariance when the number of observations exceeds the explanatory variables, or called high-dimensional data. The explanatory dataset is generated from the normal distribution, contaminated normal distribution, and uniform distribution. The binary of the response variables is computed from the logit function depending on the explanatory variable. The highest average accuracy percentage evaluates to propose the performance of the classification methods in several situations. Through simulation results, the LDA was successful when using large sample sizes, but the RDA performed when using the most sample sizes.
Solving One Species Lotka–volterra Equation by the New Iterative Method (NIM)
Authors: Batiha Belal
Published: May 2023

In this paper, we investigate the use of the new iterative method, referred to as the NIM, for solving the one species LotkaVolterra equation. This equation, which describes the dynamics of populations in ecological systems, has been widely studied in the field of mathematical biology. However, finding an analytical solution to this equation can be challenging. To overcome this, we propose using the NIM as an alternative method for solving the equation. To demonstrate the effectiveness of the NIM, we conduct a comparative study between it and other wellestablished techniques such as the differential transformation method (DTM), the variational iteration method (VIM), and the Adomian decomposition method (ADM). Through numerical simulations, we show that the NIM is able to accurately and efficiently solve the one species LotkaVolterra equation, making it a promising tool for researchers in the field of mathematical biology.

Authors: Pachar Monica , Levy Jacqueline
Published: May 2023

Lepra es una enfermedad crónica granulomatosa, causada por M. leprae y M. lepromatosi, afecta la piel y los nervios periféricos. Además del ser humano, infecta al Dasypus novemcinctus y otros mamíferos.

Es una enfermedad tropical desatendida que afecta millones de personas en el mundo y aún con reportes de casos en Panamá. A pesar de las campañas internacionales de erradicación, esto no ha sido posible, además aún existen interrogantes sobre la dinámica de transmisión, así como el rol de los reservorios naturales en la persistencia de esta enfermedad.

Las técnicas diagnósticas que seguimos utilizando son las mismas de hace 100 años y el tratamiento consiste en poliquimioterapia con varios antibióticos que actúan a diversos niveles del Mycobacterium. Aunque se han logrado avances en los esquemas de tratamiento, la taza de curación no es del 100% y existen reportes del surgimiento de resistencia antimicrobiana a componentes de los esquemas.

Published: May 2023

El daño hepático inducido por medicamentos representa una causa frecuente de falla hepática aguda y engloba una serie de reacciones asociadas a daño directo de las células hepáticas mediante mecanismos inmunes o reacciones idiosincráticas.
Su incidencia es difícil de determinar; sin embargo, se reconoce como un efecto adverso poco frecuente. Dependiendo del tipo de alteración enzimática, se pueden dividir en 3 grandes grupos: colestásicas, hepatocelular y mixtas.
Debido a la diversidad de mecanismos asociados, la presentación clínica es heterogénea y puede presentarse con distintos grados de severidad, desde pacientes asintomáticos hasta el desarrollo de falla hepática aguda fulminante.
Es un diagnóstico de exclusión y se deben descartar todas las posibles causas previo a encasillar a un paciente con este diagnóstico. El tratamiento, en términos generales, consiste en suspender el agente causal junto con tratamiento de soporte; no obstante, dependiendo de la etiología, pueden ofrecerse terapias específicas.
Relationship Between Growth Strategies and SME Success / Failure: The case of SMEs in the Western Region of Cameroon
Authors: Ndifor Clement Dr. Ndindah
Published: May 2023

Just like most economies around the globe, SMEs are of extreme importance to the Cameroonian economy. They constitute the greatest part of the business population and contribute significantly to GDP, job creation, as well as income distribution, and the fight against poverty. Despite their contribution, this category of business still experiences high failure rates. The lack of a strategic approach in the management of SMEs alongside other factors has been reported to be responsible for these high failure rates. However, the inhabitants of the Western Region of Cameroon have proven to be highly successful in their business ventures. While their business success is extensively reported, studies that provide empirical evidence of the association between the growth strategies they used and SME success are almost inexistent; thus, the purpose of this study. The study made use of a pre-tested questionnaire that was administered to 500 SME owners/managers in the Western Region of Cameroon. After consistency checks, 403 returned questionnaires were retained for the study. Findings from this study revealed that there exists a significant association between the use of growth strategy and SME success/failure in the Western Region of Cameroon. It is therefore recommended that SMEs in this region make more consistent and deliberate use of strategy to improve business success chances.

Authors: Kehinde Shamusideen , KASSIM  , Ishola Rufus , AKINTOYE
Published: May 2023

The study examined the value relevance of ESG information disclosures in healthcare sectors, by observing about 15 companies in sub-Saharan Africa (SSA), from 2006-2020, using a panel regression analysis. The study employed four models to explicate the individual and aggregate effect of the value relevance of the disclosure, ESG information, and Variance Inflation Factor was used to confirm the absence of the problem of multicollinearity. Signalling theory and Agency theory were considered in this study. Our findings therefore expound that the ESG disclosures, either aggregately or individually, positively augments the value of healthcare companies significantly, except for social disclosures with an insignificant effect. We further compare the value relevance of ESG disclosure against the profitability performance of healthcare companies in SSA. Hence, findings revealed that ESG disclosure is of higher value relevance compared to profitability performance. The study therefore concludes that the disclosure of non-financial information, ESG, as against financial information, Returns on Asset, augments the value of an average healthcare company in sub-Saharan Africa.

Authors: Humayra Farah
Published: May 2023

This study aims to examine the Service Quality (Servqual) and Price Conformity effect on Repurchase Decision with Customer Satisfaction as an intervening variable for users of goods delivery services. The population in this study are users of delivery services in the Bireuen District. The number of samples used was 310 people. Data were processed using the SEMAMOS. The result concludes that in Delivery Service Companies in Bireuen District, servqual influences satisfaction, price conformity influences satisfaction, Servqual influences repurchasing decision, price conformity influences repurchase decision, satisfaction influences repurchasing decision, satisfaction mediates the servqual influence on repurchase decision, and satisfaction mediates price conformity influence on repurchase decision. In proving mediation, it concludes that satisfaction is useful in the model as a partial mediator for servqual influencing repurchase decisions and price confirmation influencing repurchase decisions. Thus overall, it has been proven that the model of increasing repurchase decision is a function of increasing servqual, price conformity, and customer satisfaction.

Published: May 2023

This study examines a case study and impact of predicting early diabetes in United States through the application of Logistic Regression Model. After comparing the predictive ability of machine learning algorithm (Binomial Logistic Model) to diabetes, the important features that causes diabetes were also studied. We predict the test data based on the important variables and compute the prediction accuracy using the Receiver Operating Characteristic (ROC) curve and Area Under Curve (AUC). From the correlation coefficient analysis, we can deduce that, out of the 16 PIE variables, only “Itching and Delayed healing” were statistically insignificant with the target variable (class) with a value of 83% and 33% respectively while “Alopecia and Gender/Sex” has a negative correlation with the target variable (class). In addition, the Lasso Regularization method was used to penalize our logistic regression model, and it was observed that the predictor variable “sudden_weight_loss” does not appear to be statistically significant in the model and the predictor variables “Polyuria and Polydipsa” contributed most to the prediction of Class "Positive" based on their parameter values and odd ratios. Since the confidence interval of our model falls between 93% and 99%, we are 95% confident that our AUC is accurate and thus, it indicates that our fitted model can predict diabetes status correctly.

Published: May 2023

Ethanolic leaf extract of Annona senegalensis was studied for acute toxicity and some haematological parameters in albino rats. The method described by Karbar as modified by Aliu and Nwude was used for acute toxicity study in 30 albino rats. One hundred rats were randomly selected into five groups of 20 rats each, that is, groups 1-5, group 1 was the control and groups 2-5 were administered the ethanolic leaf extract for 28 days of the doses of 100, 200, 300 and 400 mg/kg respectively and blood samples were collected for the determination of the haematological parameters using standard methods described by Coles and Schalm. The extract was screened for phytochemical and elemental components using standard protocols. The phytochemical screening revealed the presence of carbohydrates, cardiac glycosides, terpenoids and flavonoids. The elemental screening revealed the presence of some elements in milligram per kilogram concentration such as 7.202 for iron, 0.893 for copper, 6.637 for magnesium, 0.014 for lead, 0.070 for chromium, 0.057 for cadmium, 0.604 for cobalt, 1.732 for zinc and 2.362 for manganese. The acute toxicity study was 2400 mg/kg which is classified as non label according to the report of Organization for Economic Cooperation and Development (OECD) which means it is tolerable at that level. The prolonged administration of the ethanolic extract showed significant increase (P<0.05) in White Blood Cell (WBC), Red Blood Cell RBC), Packed Cell Volume (PCV), Haemoglobin concentration (HB), Platelet Count (PLT) and Differential Leucocytes Count (DLC) throughout the duration of the study. In conclusion the ethanolic extract is found to be tolerable and an increase in the haematological parameters in the treated albino rats, thus, has a good immune boosting and treatment of anaemia potentials.

Derecho a la defensa vs. jurado de enjuiciamiento de magistrados Propuesta de una ley ideal
Authors: Ovelar Escobar Milciades , Hermosilla de Olmedo María Luisa , Olmedo Hermosilla Jaqueline
Published: May 2023

Como ya resultaba insostenible el estéril confrontamiento entre el poder político y el jurisdiccional que venía soportando el sistema judicial del Paraguay, debido a la directa injerencia de los actores políticos en el enjuiciamiento de jueces y agentes fiscales, se debatió seriamente el asunto, desde el año 2.018, hasta que finalmente, en el 2.021 se promulgó la nueva ley que regula el funcionamiento del Jurado de Enjuiciamiento de Magistrados (JEM). Es una situación que, desde un principio, resulta difícil de superar, puesto que la propia Constitución Nacional establece un Jurado integrado por dos senadores y dos diputados, los cuales representan a un robustecido Poder Legislativo que, a su vez, condiciona en alguna medida, a la propia Corte Suprema, cuyos dos ministros también integran el referido órgano juzgador. Finalmente, se completa con otros dos miembros del Consejo de la Magistratura, cuya fuente de asignación también es política. Así pues, desde el punto de vista de la conformación del JEM, se erige una superposición del poder político.

IDENTIDADE VERSUS ENSINAR DOCENTE: VERIFICAÇÃO DOCENTE COM O ENSINAR A DISCIPLINA DA MATEMÁTICA NOS ANOS INICIAIS DO ENSINO FUNDAMENTAL (1º AO 5º ANO).
Authors: Santos Allan Gomes , Jimênez Luis Ortiz
Published: May 2023

Diante do objetivo geral desta investigação que foi analisar a identificação dos docentes com a disciplina da matemática ao ensinar nos anos iniciais do ensino fundamental, no contexto dos professores da Rede municipal de ensino de Maceió e alunos-professores do 8º período do Curso de Pedagogia, buscou-se verificar a identificação docente com a matemática associado ao sentimento de gostar e, portanto, os desafios enfrentados com o lecionar a matemática sem ter afinidade em seu ofício de ensinar. Através de uma pesquisa do tipo não experimental, um estudo exploratório que antecedeu a investigação de alcance descritivo e um enfoque quantitativo com corte transversal, foi utilizado como procedimento de coleta de dados questionários fechados. A análise de dados aconteceu em três etapas, sendo: na primeira etapa voltou-se para o conhecimento da percepção do foco de pesquisa com um levantamento de dados dos professores atuantes nos anos iniciais do Ensino Fundamental e a relação com as notas obtidas no IDEB referente a proficiência da matemática pelas escolas pesquisas; numa segunda etapa, a análise tratou-se para o contexto dos alunos-professores pertencentes do 4º ano de formação do Curso de Pedagogia e na última etapa uma análise ampla e relacional com todos os dados das etapas anteriores e com um olhar comparativo dos dados antecedentes pesquisados nos anos 2013 e 2014. A pesquisa teve como aporte teórico, a contribuição de autores para quatro eixos investigativos, como: saberes docentes (Freire (1996), Pimenta (1998, 2002), Gauthier et al. (1998), Tardif (2003) e Cunha (2004)); competências docentes (Masetto (1998), Perrenoud (2000, 2002)); aprendizagem significativa (Shulman (1986), Ausubel (1982)); identificação/gostar do fazer docente ou identidade docente (Nóvoa (1992, 1995), Paulo Freire (1996), Gatti (1996), Libaneo (2002), Dubar (2005, 2009), Tiba (1996)) e conflitos cognitivos (Vigotsky (1984); Davydov (1988); Morin (2000)). Com as análises os resultados dos dados revelaram que dentre os percentuais encontrados nossos públicos-alvo possuem uma falta de identificação em seu fazer docente e em sua práxis pedagógica e, ainda, um sentimento de não gostar da área da matemática com indicativos de distanciamento com a matemática em formações anteriores e atual para ser um bom profissional na área, ponto fundamental para que o enlace entre seus saberes prévios e seus processos de formação fomentem numa caminhada para um ensinar com mais dedicação, sentimento e amor. Interessa conhecer e compreender tais comportamentos e sentimentos docentes, que embora não explícito nos contextos educacionais, produzem efeitos significativos em seu ofício docente. Ao mesmo tempo, a pesquisa traz contribuições valiosas para pensarmos no ensino da matemática sem identificação e suas consequências em estudos futuros, suscitando novos olhares e formas de pensar para o processo de ensino e de aprendizagem da matemática no lado discente.

В статье представлены результаты проведенного выборочного исследования рынка труда аудиторов в российских городах - центрах Федеральных округов, в ходе которого выявлен потенциальный риск того, что в скором времени рынок окажется неспособным удерживать высококвалифицированных специалистов с современными цифровыми компетенциями в сфере аудита при условии сохранения текущего уровня оплаты труда таких профессионалов и высоких требований к их компетенциям. Как следствие, на рынке складывается ситуация, которая затрудняет цифровизацию аудиторской деятельности.

The paper presents the results of a sample survey of the labor market of auditors in Russian cities - centers of the Federal Districts. During the research a potential risk was identified that soon the market would be unable to retain highly qualified specialists with modern digital competencies in the field of audit, if the current level of salary of such professionals and high requirements for their competencies remain. As a result, the market is facing a situation that makes it difficult to digitize audit activities.

Повышение производительности финансовой деятельности относится к одной из наиболее актуальных, но малоизученных направлений в современной теории государственного управления. В данном исследовании предлагается новая концепция, позволяющая решить проблему накопления резервов неэффективности в виде излишней численности специалистов за счет использования системной методологии DEA и принципов междисциплинарной науки сервисологии. Основа предложенной оценки сравнительной эффективности базируется на выявленной в результате анализа современных методик связи между численностью населения муниципального образования (далее - МО) и численностью финансового аппарата. Новая модель оценки позволила получить табличные и визуальные данные как об эффективных механизмах управления, так и о неэффективных, т.е. обладающих резервом неэффективности. Для неэффективных объектов в качестве направления в пространстве производственных возможностей использования информационной технологии обозначены объекты-цели. Разработанная модель оценки может использоваться для оценки эффективности информационных систем различных структур управления, имеющих разветвленную сеть учреждений и выполняющих однотипные функциональные задачи.

Improving the performance of financial activities is one of the most relevant, but little-studied areas in modern theory of public administration. In this study, a new concept is proposed that allows to solve the problem of accumulating reserves of inefficiency in the form of an excessive number of specialists through the use of the DEA system methodology and the principles of the interdisciplinary science of serviceology. The basis of the proposed assessment of comparative efficiency is based on the relationship between the population of the Moscow region and the size of the financial apparatus, revealed as a result of the analysis of modern methods. The new assessment model made it possible to obtain tabular and visual data on both effective management mechanisms and ineffective ones, i.e., having a reserve of inefficiency. For the latter, objects-targets are designated as a direction in the space of production possibilities of information technology. The developed assessment model can be used to assess the effectiveness of information systems of various management structures that have an extensive network of institutions and perform the same type of functional tasks.

В наше время все больше финансовых учреждений и сфер бизнес-ритейла переходят на использование микросервисных приложений. Это обусловлено удорожанием поддержки полноценной виртуальной инфраструктуры, удобством микросервисов в обслуживании и обеспечении отказоустойчивости. Однако для создания полноценно защищенной от внешнего или внутреннего воздействия среды микросервисных приложений требуется грамотная настройка кластера. В статье рассмотрено несколько концепций для развертывания нового кластера, в частности в среде Azure Kubernetes Service (AKS).

Nowadays, more and more financial institutions and business retail sectors are switching to the use of microservice applications. This is due to the increased cost of supporting a full-fledged virtual infrastructure, the convenience of microservices in service and ensuring fault tolerance. However, to create a fully protected environment from external or internal impact of microservice applications, competent configuration of the cluster is required. The article discusses several concepts for deploying a new cluster, specifically in an Azure Kubernetes Service (AKS) environment.

В условиях глобализации мировой экономики, экономической нестабильности одним из наиболее сложных вопросов, с которым сталкиваются менеджеры компаний, является определение оптимальной структуры капитала, которая будет содействовать достижению основной цели компании – максимизации ее акционерной стоимости и благосостояния ее собственников. В рамках стоимостного подхода к оценке бизнеса в работе была сформулирована экономико-математическая модель оптимальной структуры капитала, позволяющая построить различные сценарии распределения капитала с учетом плановых результатов финансово-хозяйственной деятельности, при которой акционерная стоимость как основной критерий эффективности деятельности компании примет максимальное значение при заданном уровне долговой нагрузки. Нами было рассчитаны доходность собственного капитала по модели CAPM, при расчете ставки использовался глобальный подход, который учитывал несистематические риски, рассчитана средневзвешенная стоимость капитала и стоимость компании для каждого возможного уровня долговой нагрузки. Было проведено сценарное моделирование оптимальной структуры капитала на примере компании-производителя комбикормов.

Given the globalization of the economy and the economic instability, one of the most complex issues facing company managers is the determination of the optimal capital structure that will facilitate the achievement of the company's main goal of maximizing its shareholder value and the welfare of its owners. As part of the value approach to business valuation, an economic and mathematical model of the optimal capital structure was formulated in the work, making it possible to create various capital allocation scenarios taking into account planned financial and business performance, when shareholder value, as the main criterion for the company's performance, takes on the maximum value at a given level of debt burden. We calculated the return on equity under the CAPM model, used the global approach to calculating the rate, which took into account non-systemic risks, calculated the weighted average cost of capital and the company's value for each possible level of debt burden. We performed scenario modeling of the optimal capital structure based on the example of a feed producer.
