Authors: Hurtado Banguero Andrés Felipe , Paredes Valencia Carlos Mario
Published: October 2024

Una tecnología habilitadora de la industria 4.0 son los llamados Gemelos Digitales (Digital Twin), los cuales utilizan diversos enfoques que buscan proporcionar una estructura sólida y coherente para el desarrollo y la implementación de los mismos. Estos enfoques pueden incluir la modularidad, la reutilización de componentes, la estandarización de procesos y la integración de otras tecnologías emergentes. Se destaca la importancia de adoptar enfoques que permitan la flexibilidad, la escalabilidad y la interoperabilidad de los Gemelos Digitales en entornos industriales complejos con características de sistemas tolerante a fallos. En este artículo se presenta una revisión del estado del arte relacionado con el diseño de Gemelos Digitales con atributos relacionados con la tolerancia a fallos para entornos de manufactura y el sector industrial en general. En esta revisión de literatura, se utilizó la metodología PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) para garantizar un enfoque sistemático y riguroso en la selección y análisis de los artículos relevantes. Inicialmente, se definieron criterios de inclusión y exclusión para filtrar la literatura disponible. Posteriormente, se llevó a cabo una búsqueda en bases de datos académicas utilizando tópicos específicos relacionadas con gemelos digitales, Frameworks y modelos, sistemas tolerantes a fallos y los microservicios. Después de una revisión de títulos, resúmenes y contenido completo de los artículos, se seleccionaron finalmente 23 reportes que cumplieron con los criterios establecidos. Estos artículos fueron analizados para obtener una visión integral de los avances y tendencias actuales en el campo de los gemelos digitales. Se observó una tendencia hacia la adopción de arquitecturas basadas en microservicios para mejorar la flexibilidad y la escalabilidad de los sistemas. La literatura destaca que los microservicios pueden contribuir a la resiliencia de los Gemelos Digitales al permitir la recuperación ante fallos de forma aislada y sin afectar al funcionamiento global del sistema. Sin embargo, no todos los enfoques en la creación de Frameworks para gemelos digitales incluyen el atributo de tolerancia a fallos. De igual manera, se destaca la necesidad de una validación en escenarios del mundo real para fortalecer la practicidad de los Frameworks y se menciona la exploración de la adaptación dinámica para responder a estándares emergentes y tecnologías en evolución, especialmente para garantizar la resiliencia del sistema.

En la actualidad, todos los países reconocen la importancia de mitigar los impactos derivados de las actividades industriales, a partir de esto, se han establecido a nivel mundial objetivos de desarrollo sostenibles (ODS) los cuales abarcan problemáticas con el medio ambiente, uso de los recursos naturales, pobreza, escasez de alimentos, crecimiento económico, entre otros. Por consiguiente, los países se han propuesto aumentar la productividad agrícola de manera sostenible, lo cual ha dado paso a mejorar los sistemas de producción mediante el análisis de los factores asociados a su productividad, tales como las hectáreas sembradas, número de habitantes, toneladas exportadas e importantes, oferta interna y el desperdicio de la cadena de suministro. En el presente artículo, se aborda lo concerniente a la producción agrícola en países de Latinoamérica, teniendo así el propósito de examinar mediante análisis estadístico los aspectos claves para la mejora y sostenibilidad de este sector. Por ende, se definieron variables independientes correspondiente a las importaciones, exportaciones, hectáreas sembradas, oferta interna, desperdicio de la cadena de suministro y el número de habitantes. Además, mediante el uso de regresión lineal múltiple se determinaron las variables significativas que afectan la producción agrícola. Finalmente, surge la necesidad en los países de comprobar si las toneladas de alimentos que proyectan producir se alinean con su realidad. En el caso de Brasil considerado como uno de los mayores productores, se llevó a cabo un análisis de capacidad realizado en Minitab ®, permitiendo evaluar si el sistema de producción agrícola puede cumplir con las especificaciones establecidas a corto y largo plazo. Sumado a esto, se contemplan factores medio ambientales, tecnológicos, sociales, políticos y económicos que pueden llegar a afectar la previsión de la producción agrícola.

Implementación de estrategias para incentivar el ahorro energético en la comunidad de la vereda Barcelona del municipio de Villavicencio, Colombia
Authors: Monroy Moyano Wilson
Published: October 2024

Este trabajo nace de la problemática presentada por el cambio climático, el calentamiento global del planeta, la lluvia ácida, el aumento de los componentes ultravioleta de la radiación solar, los residuos radiactivos, la desertización, las sequías, etc., etc., todo lo anterior como consecuencia directa o indirecta de las actuaciones del sistema energético. Otra dificultad mundial es la desigual en la distribución espacial de las fuentes de energía primaria de carácter convencional (carbón, petróleo, gas natural), junto con su agotamiento y su influencia en el sistema económico vigente. Estas características básicas del sistema energético mundial deben llevar a la sociedad actual a reflexionar e intentar poner los medios para que la situación se vaya corrigiendo hacia perspectivas de futuro más sostenibles. Esto sólo se conseguirá a través de una serie de medidas de diversa naturaleza encadenadas temporal y espacialmente, como son: el ahorro y la mejora de la eficiencia de los sistemas, una mejor y más solidaria distribución de la energía final y, la progresiva sustitución de las fuentes de energía convencionales (agotables y contaminantes) por fuentes de energía renovables (no agotables y mucho menos contaminantes) que además están mejor distribuidas. El concepto de eficiencia energética hace referencia a reducir el consumo de cualquier tipo de energía y por consiguiente los posibles impactos ambientales asociados, con la eficiencia energética se pretende obtener mejores resultados en cualquier actividad usando la menor cantidad posible de recursos energéticos. Es por lo anterior que con este trabajo se aspira a contribuir en al ahorro y la eficiencia energética de una población con muchas necesidades como lo es la vereda Barcelona del municipio de Villavicencio – Meta – Colombia. El trabajo desarrollado se enfocó en un proceso de aplicaciones de estrategias relacionadas con la disminución del consumo de energía convencional. El ahorro energético y el aprovechamiento de los recursos renovables, son dos aspectos fundamentales en la intención de preservar las condiciones climáticas del planeta, en nuestro entorno y en nuestras comunidades rurales el desconocimiento sobre la importancia del ahorro energético es muy alto, es por esto que se pretende dar a conocer cómo empezar enfrentar este problema y dar soluciones reales como es el aprovechamiento de energías alternativa que se sirvan para generar energía y de esta forma contribuir al desarrollo sostenible de una comunidad. Finalmente, con los resultados derivados, se pretenden analizar los resultados desde 3 aspectos: el económico (disminución en el recibo de energía eléctrica, KW/h), el ambiental (utilización de recursos naturales de energía) y el social (familias beneficiadas).

PRACTICES AND PERCEPTIONS OF L1 AND TRANSLATION USE: THEMATIC ANALYSIS OF A FOCUS GROUP INTERVIEW W ITH KAZAKHSTANI SECONDARY SCHOOL EFL TEACHERS
Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Smagul Aidana
Published: October 2024

From the latter half of the 20th century to the present day, monolingual or English-only teaching has been conventionally considered the optimal approach in English Language Teaching (ELT) literature and research. Nevertheless, there is a growing acknowledgement that mainstream ELT theory may of-fer a less precise portrayal of classroom dynamics than the actual observed reality. Consequently, this paper aims to explore teachers’ practices and perceptions regarding the use of learners’ first language (L1) and translation in EFL classrooms. A focus group interview (FGI) was conducted with in-service secondary school EFL teachers from Kazakhstan who were selected through non-probability sampling to achieve this goal. Thematic analysis was applied to scrutinize the interview data. The results revealed three primary themes: teaching English through L1, learners’ English level and L1 use, and drawbacks of monolingual teaching. Each theme and sub-theme is substantiated by quotations from the interview and discussed in connection with ELT theory and relevant studies.

Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Sadyrova Mansiya , Mukhtarova Karlygash , Makasheva Klara , Imanbayeva Sandugash
Published: October 2024

The article reveals the problems that rest on the choice of profession of school graduates, the transi-tion of young people from study to work, the difficulty with professional orientation, and, as a result, high unemployment in the labor market. The listed problems cover almost many countries of the world. Among the reasons for such a negative growth, the authors of the publication explain, first of all, changes in the functioning of the educational system, which can eventually lead to socio-economic risks and social inequality. The other side of the above-mentioned problem noted that the existing educational practice in many ways does not provide the order of the state and society for the formation of a graduate of urban and rural schools as a subject of socio-professional self-determination. The reasons rest on the following factors:– a low level of career guidance interaction between educational organizations of different levels, which generates the substitution of practice-oriented forms of professional orientation with psychologi-cal diagnostics and counseling;– the use of outdated inefficient approaches without taking into account modern information tech-nologies and more.The purpose of the presented research is to identify, in the regional context, the transformation of professional preferences of high school students in urban and rural schools as a strategy for future em-ployment.As a result of the survey conducted by the authors among school graduates, conclusions and pro-posals were formulated to optimize preparatory and organizational work among high school students to improve the methodology of career guidance activities. These proposals formed the basis for the developed sociological survey program and documents for school administrations in order to conduct annual monitoring to identify students’ professional preferences, taking into account new trends in the employment market.

Published: October 2024

In the modern education system, it is impossible to imagine the learning process without using the Internet, which has become an indispensable tool for all subjects of education. At the moment, the participants of the educational process widely use modern technologies as a basis for the transfer and accumulation of knowledge. In this regard, the technology of blogging and using an educational blog on the Internet is gaining popularity, which allows the teacher to plan the learning process more effectively, as well as summarize and evaluate its results.Since blogs offer wide opportunities for communication between people united by common inter-ests, it is advisable to use them as a means of developing communication skills. However, not every teacher today has the skills and knowledge in the field of information technology sufficient to effectively blogging and using an educational blog.The purpose of this study was to determine the attitude of Physics teachers working in secondary education organizations of the Zhetysu region of the Republic of Kazakhstan to the need to blogging and using a blog as a means of developing communication skills. 116 Physics teachers took part in the study. The survey method was used in the study. When processing the results, the frequency of responses and percentages for each response are counted. As a result of the conducted research, it was revealed that the majority of teachers surveyed favorably relate to the blogging and using an educational blogs in Physics lessons along with traditional teaching tools. The necessity of conducting training seminars and courses on the blogging and using an educational blog at the level of educational organizations has also been identified in order for Physics teachers to form an understanding of the principles and methods of blogging and using a blog. The article also reveals the need to develop educational blog management strategies for teachers to understand how to integrate, use and maintain an educational blog in teaching Physics, as well as the effective use of time and effort when blogging. In addition, it is concluded that it is necessary to continue research on solving problems that teachers may have when blogging and using an educational blog as an additional tool in teaching Physics.

Authors: El-Sheikh Ahmed A. , Ali Mohamed C. , Abonazel Mohamed R.
Published: October 2024

High-dimensional problems involve datasets or models characterized by a substantial number of variables or parameters prevalent across various domains such as statistics, machine learning, optimization, physics, and engineering. Challenges in these scenarios include computational complexity, data sparsity, over-fitting, and the curse of dimensionality. This study introduces two innovative techniques that combine the Random Forest machine learning approach with both the least absolute shrinkage and selection operator and the elastic net, which are statistical methodologies tailored to address high-dimensional challenges. We compared performance evaluations of these hybrid methods against traditional statistical approaches and standalone machine learning methods. The assessment is conducted using goodness-of-fit measures and involves both Monte Carlo simulation and a real-world application. The findings show that the strategies proposed in this study exhibit superior performance compared to conventional approaches when tackling high-dimensional challenges.

This paper presents a study on nonlinear difference equation systems of 6k + 3 order. The equations are of the form pn+1 =pn−(6k+2) / (±1±qn−2k rn−(4k+1) pn−(6k+2)), qn+1 =qn−(6k+2) / (±1±rn−2kpn−(4k+1) qn−(6k+2)),rn+1 =rn−(6k+2) / (±1± pn−2kqn−(4k+1) rn−(6k+2)), k ≥ 0 where n is a non-negative integer (belonging to the set N0 = N ∪ {0}) and the starting values p−l , q−l , r−l , l ∈ {0, 1, . . . , 6k+2} are arbitrary nonzero real numbers. We propose a systematic approach to solve this system, introducing a novel technique to find explicit solutions. The main outcomes of our study are the explicit solutions derived from the considered system. The study examines four different cases of this system and provides numerical examples to illustrate the results. The numerical examples demonstrate the behavior of the system for various initial conditions. The study is concluded with graphical representations of the solutions for each case, providing insights into the behavior of the systems.

NOTES ON THE HISTORICAL GEOGRAPHY OF THE CULTURAL LANDSCAPE BALTA-CHOKRAK VILLAGE IN SOUTHWEST CRIMEA AT THE END OF THE 18TH – THE FIRST HALF OF THE 20TH CENTURY
Authors: Ruev Vladimir , Leybenson Yu.
Published: October 2024

This article presents a study of the surviving elements of the cultural landscape and the reconstruction of the disappeared elements of this landscape using the example of the abolished village of Balta-Chokrak in the Crimean Mountains, as well as a demonstration of the possibilities of such an approach to other rural cultural landscapes of Crimea. The authors developed a classification of the degree of preservation of the historical rural cultural landscapes of Crimea, according to which the cultural landscape of the village of Balta-Chokrak is characterized by a low degree of preservation (due to the destruction of the previous planning of residential development as a result of modern economic activity). Despite the above fact, single elements of the relict rural landscape have been preserved on the territory of the former village. Thanks to documentary evidence and a survey of the territory, the researchers were able to determine the location of various elements of the cultural landscape of the village, such as: a water supply source, colonists’ houses, an agricultural district with arable and pasture lands, small wood forest and areas for stone mining, transport infrastructure, religious buildings and necropolis. It is also important that since the necropolis of the village of Balta-Chokrak is one of the few surviving elements of the cultural landscape. Therefore, a complete catalog of his tombstones and their fragments is also presented.
BIRTH OF THE WOMEN'S MOVEMENT IN INDEPENDENT PAKISTAN
Authors: Kamla  , Akansha
Published: October 2024

How did the women's movement emerge in Pakistan and what factors created it? Was the women's movement born only from women's organizations? Do only urban women's organizations lead the entire country? Are class differences relevant here? Are knowledge creation and individual and collective consciousness the result of geographical and professional background? We can get answers to these questions only by analyzing theories. The path on which the women's movement in South Asia is moving is the path of integrating gender with development. Women's organizations in South Asian countries are fighting against the elements inimical to women's identity and are strongly opposing the politicization of religion. South Asian women are still trying to restore peace. Along with this, their movement is moving forward with other important issues, such as gender equality which is demanding equality at the level of law, capacity building, participation and governance. The struggle of the South Asian women's movement is visible on every issue. Lack of political power among women, gender inequality, health related issues, need for justice, human rights issues, need for peaceful development etc. are important issues but the path of women's movement in all these is difficult. Lack of state initiatives, feudal and patriarchal social structure and globalization market system and demand for cheap labor are making the path of this struggle more difficult.
Many feminists believe that in the context of South Asia, women's movement and feminist movement are two different concepts. While women's movement talks about equal rights in a democratic structure, feminism challenges the legitimacy of a system which is oppressive for women.

Authors: Çetin Kemal , Şarkaya Koray
Published: October 2024

The administration route of an active ingredient and the materials used to deliver it are as important as the synthesis of that active ingredient. For the treatment to be effective, the active ingredient must be present in the right amount and in the right place at the right time. Therefore, researchers have been studying a wide variety of drug delivery systems, taking into account the route of administration of the drug, its half-life, and its effective and toxic amounts. Because of its numerous benefits, nanotechnology has attracted attention in pharmaceutical research as well as many other fields. Nanoparticles have the potential to disperse hydrophobic drugs in an aqueous solution, deliver drugs to the targeted site, and thus selectively direct therapeutic agents such as antineoplastic drugs. This study provides a detailed discussion of the many inorganic, polymeric, and lipid-based nanoparticulate systems designed for drug delivery.

El propósito de este estudio es cuantificar la carga cardiovascular (CC) de trabajo en un sector industrial y su relación con la sintomatología musculoesquelética, en la industria manufacturera de neumáticos. Se estudió a 92 sujetos varones, de entre 24 y 62 años, operadores de producción. Los resultados mostraron que el sector industrial evaluado presenta un esfuerzo físico equivalente a una CC de 24%, una correlación significativa en el tiempo con molestias en el segmento muñeca-mano y la duración de cada episodio (p 0,05). Se concluye que, existe relación directa con el trabajo de las extremidades superiores, específicamente el segmento más distal, por lo que una alta carga cardiovascular podría ser un factor de riesgo para el desarrollo de trastornos musculoesqueléticos de la extremidad superior y a su vez el trabajo exigente del mismo segmento corporal elevaría mayormente el %CC respecto a otras partes del cuerpo exigidas.

Niosomes, also known as nonionic surfactant vesicles, are small lamellar structures that are created by combining nonionic surfactants from the alkyl or dialkyl polyglycerol ether category with cholesterol, and then hydrating them in water-based solutions. These are vesicle systems resembling liposomes that can be utilized as carriers for drugs that are both amphiphilic and lipophilic. The production process of niosomes is derived from liposome technology. The fundamental manufacturing method remains unchanged, wherein the lipid phase is hydrated by the aqueous phase. The lipid phase can consist of either a pure surfactant or a combination of surfactant and cholesterol. Niosomes effectively tackle the challenges associated with medication insolubility, instability, inadequate bioavailability, and fast degradation. The amphiphilic character of niosomes, which combines both hydrophilic and lipophilic properties, enhances their capacity to encapsulate medicines that are either hydrophilic or lipophilic. Cholesterol is frequently utilized as one of the ingredients. Preserving the stiffness of the niosome structure. The present article discusses the essential elements of niosomes, including their structural constituents, methods of manufacturing, and their uses in different disorders.

The challenge of resistance to synthetic antimicrobials necessitates new alternative solutions. Medicinal plants are rich in active compounds with various medicinal properties that can be used in treatment of urinary infections. This work aims to highlight the value of Annona senegalensis and Detarium microcarpum by evaluating phytochemical and antimicrobial potentials of their leaf extracts. Qualitative and quantitative analyses were carried out using color and precipitation reactions and spectrophotometric assays. The antiradical activity was evaluated using the DPPH test, and the antimicrobial activity was assessed by the agar diffusion method. Phytochemical screening showed that both plants contain anthraquinones, catechic tannins, coumarins, flavonoids, reducing compounds, sterols and terpenes. Hydroethanolic extract of Detarium microcarpum and A. senegalensis showed IC50 inhibition percentages of 0.20 mg/mL and 0.22 mg/mL respectively. Regarding antimicrobial activity, the hydroethanolic leaf extracts of D. microcarpum and A. senegalensis were found to be bactericidal and fungicidal against the tested bacteria and molds. This extract showed more pronounced antimicrobial activity than amoxicillin and ciprofloxacin, which are synthetic antimicrobials. Diversity of secondary metabolites and notable antimicrobial activity of D. microcarpum and A. senegalensis may justify their use in traditional medicine for treating urinary infections in Benin.

Background: Surgical site infection (SSI) is a common complication after cesarean section in Tanzania, with high rates of infection and multidrug-resistant isolates reported. Understanding bacterial etiology and antibiotic susceptibility patterns is crucial for effective treatment and prevention. Therefore, this study aimed to determine the bacterial etiology, antibiotic susceptibility patterns, and treatment modalities of SSI among post-cesarean delivery women in the Iringa region. Methods: A cross-sectional study involving 162 women with SSI was conducted across five hospitals in Iringa. Data on demographics were collected using a structured questionnaire, and wound discharge samples were taken for culture and sensitivity testing. Definitive treatment modalities were identified from patients’ files. Data analysis was performed using SPSS version 20, with chi-square tests used to identify associations, and a p-value < 0.05 considered significant. Results: Among 162 participants, 59.7% had superficial SSIs and 35.2% had deep SSIs. Culture positivity was 96.3%, with 53.2% being gram-positive and 37.2% gram-negative. Staphylococcus aureus was the most commonly isolated pathogen (40.1%), with 64.6% of cases being methicillin-resistant (MRSA). Resistance to vancomycin and chloramphenicol among gram-positive isolates was 3.1% and 13.8%, respectively. Non-surgical management was provided to 58% of the participants, while Staphylococcus aureus infections were significantly associated with surgical intervention (OR = 1.38, p = 0.001). Conclusion: Staphylococcus aureus, particularly MRSA, was the most prevalent pathogen in post-cesarean SSIs. Antibiotic resistance was common, and surgical intervention was significantly associated with Staphylococcus aureus infections.
