Published: February 2025

Topicality. This study is relevant due to the need to address the problem of intensifying the negative impact of intensive agricultural activities on the zonal soil subtype of ordinary chernozem. In the northern sub-zone of the Steppe of Ukraine, the ordinary chernozem undergoes significant changes in all agrochemical parameters, especially in its humus content, due to the long-term impact of anthropogenic factors. Purpose. The research is aimed at generalising the research on the historical development of chernozems, assessing changes in the humus content of ordinary chernozem under the long-term influence of anthropogenic factors, comparing its content in the soil with virgin plots, and developing scientific recommendations for agrochemical methods of preserving soil fertility and stopping the loss of humus. Material and Methods. Long-term studies were conducted at the main experimental facilities of the SE Institute of Grain Crops of NAAS of Ukraine – Erastivska Research Station and the Educational and Research Centre of Dnipro State Agrarian and Economic University. Analytical studies of the selected soil samples were carried out according to standardised methods at the Dnipro branch of the Soil Protection Institute of Ukraine. Studies to determine soil quality and organic matter content were carried out in accordance with DSTU 4289:2004. Results. The studies have convincingly shown that the most significant changes in humus content were observed in the 0–5 cm layer – 8.25 % on virgin soil and 4.2 % on arable land, i.e. the difference between them was 4.05 %. The virgin soil significantly exceeded the arable land in terms of humus content up to a depth of 0–60 cm, and only from a depth of 60–65 cm and deeper did the humus content of the arable land begin to exceed the virgin soil. The increase in humus content from a depth of 60 cm on arable land is explained by the formation of labile humus, which migrated to the lower subsoil layer together with precipitation. Conclusions. The results of the research have shown that long-term ploughing of chernozem soils and their intensive use in agricultural production not only leads to the development of dehumification processes, but also contributes to alkalinisation of the arable layer of soil as a result of the rise and concentration of calcium and magnesium hydrocarbons in soil. Forecasts of the humus balance indicate that to fully compensate for its losses from mineralisation in the current structure of agricultural areas in the Steppe zone of Ukraine, it is necessary to apply annually semi-rotted manure at a rate of 8.0 t/ha.

Published: February 2025

The work is devoted to solving the scientific and practical task of studying the impact of war on nature conservation areas using the example of Khortytsia Island, which is part of the Khortytsia National Reserve. The study used multispectral imaging data from the LANDSAT 5 satellite (MSI scanner). It is shown that as a result of the destruction of the Kakhovka Reservoir, the water level in the Dnipror River decreases, which affects the water bodies of Khortytsia Island (lakes and straits). It is established that there is a critical impact on the state of biodiversity of the island due to the reduction in the area of the water mirror in some lakes of the island or the disappearance of lakes in general. Key critical impacts for the ecology of the island ecosystem were identified, such as lowering the water level, changes in the river flow, and reducing the oxygen potential of the hydroecosystem. Conclusions were drawn on the need for detailed monitoring, implementation of restoration programs, and improvement of water quality.

Modeling of digital spatial processing under conditions of troposphere propagation of centimeter radio waves for wireless telecommunication
Authors: Peshkov Ilia W. , Borisov Dmitry N.
Published: February 2025

Objectives. A radio beam traveling through the layers of the atmosphere depends on the refractive index and its vertical variation. In this regard, attenuation may occur when radio rays propagate in a waveguide manner at low altitudes. A multipath fading effect may also occur when several rays reflected from different layers of the troposphere and having different spatial coordinates in elevation arrive at the receiver. The aim of the study is to simulate the operational algorithms of digital antenna arrays (DAA) in order to increase the range and reliability of radio communication using a tropospheric waveguide. The main advantage of the DAA consists in the high gain and controllability of the pattern shape. In order to evaluate algorithms for direction-of-arrival estimation with superresolution and beamforming, it is necessary to select an appropriate method for modeling beam propagation in the layers of the troposphere. It is proposed to use DAA to increase the range and reliability of radio communications using a tropospheric waveguide. The performance of algorithms for direction-of-arrival estimation and beamforming in the troposphere can be evaluated using ray tracing simulation.

Methods. Parabolic equations are used to estimate the path losses of radio waves in the centimeter range. A ray tracing algorithm referring to a tropospheric waveguide is used to estimate the phases in the aperture of the receiving array. A spatial correlation matrix is reliably generated to form the basis for calculating coordinates using a superresolution multiple signal classification (MUSIC) method and the weighting factor vector (algorithm for maximizing the signal-to-noise + noise ratio).

Results. Typical cases of a tropospheric waveguide based on a modified refractive index were considered. The bit error rate curves are obtained as a function of the geometry of the antenna arrays after the signal has passed through the tropospheric waveguide. Circular and spherical antenna arrays composed of directional antenna elements are considered.

Conclusions. Numerical studies suggest that the range of communication links using digital antenna arrays increases in the centimeter band. The best geometry for this purpose is circular, since providing the lowest bit error rate for binary phase-shift keyed signals.
A smoothed particle hydrodynamics approach for numerical simulation of tube heat exchangers
Authors: Korenchenko Anna E. , Sukhov Anton V.
Published: February 2025

Objectives. In the confined space of heat exchangers, heat transfer rate plays a key role. The cross-sectional shape of the tubes can affect the heat transfer characteristics. Although circular tubes are easier and less expensive to manufacture, heat transfer in heat exchangers with tubes of other cross-sections can take place at higher rates, thus providing economic advantages. This makes the mathematical modeling of hydrodynamics and heat exchange in a tube apparatus relevant and interesting both from the theoretical and applied point of view. The aim of this study is to determine the influence of the shape of the tube cross-section on the heat transfer intensity.

Methods. Numerical investigations were carried out using smoothed particle hydrodynamics. The possibilities of the smoothed particle method for resolving industrial heat transfer problems were demonstrated.

Results. Heat transfer intensity was analyzed for tubes of circular and rectangular cross-sections. In cases where the cross sections of tubes in the heat exchanger are elongated in a given direction, the influence of the tube position in relation to the oncoming flow was studied. This was performed either with the long side along the flow or across it. The influence of tube surface protrusions on heat exchange was investigated. The flow around tubes with different cross-sectional shapes was also analyzed. The features of the flow around the tubes were established, and the velocity and temperature fields in the heat exchanger volume were defined. The values of the dimensionless heat flux (Nusselt number) for each case were also found.

Conclusions. The influence of finned tubes in the laminar flow regime of heated fluid through the bundle of heat transfer tubes is insignificant. The highest value of the heat flux was observed for tubes of rectangular cross section with the long side transverse to the flow, and the difference with the data obtained for standard round tubes was found to be more than 15%.

Authors: Leontyev Alexander S. , Zhmatov Dmitry V.
Published: February 2025

Objectives. This study aims to create analytical methods for evaluating the probabilistic safety characteristics of information and software elements in digital substations in order to ensure security in different virus scenarios.

Methods. The methods of reliability theory, random process theory, and recovery theory were used.

Results. The derived integral ratios were further used to estimate the probability characteristics of information processing security when performing functional tasks in various scenarios of attacks on digital substations, as well as multiple technologies used for protection against such threats. Numerical studies of safe information processing probability of different intensities of attacks and times of their activation were conducted, in order to consider the frequency of diagnostics of the system by the service personnel and customer requirements for the safe operation of the system in a certain period. We performed calculations for various protection technologies against similar attacks on digital substations. A protection technology with system diagnostic deterministic frequency can support customer requirements in the event of accidental and relatively rare virus attacks. Security technologies consider different maintenance personnel operation modes to ensure customer fulfillment requirements for safe information processing probability and the case of deliberate attacks on digital substations in each period.

Conclusions. The technologies considered herein for information protection from attacks on digital substations can provide the necessary level of information security system operation for all types of threats. These technologies can be applied when the system diagnostics frequency increases from twice an hour to at least once every 25 minutes. Our findings underline the importance of timely monitoring of ever-changing attack environments for digital substations.

Event Driven System Design with High Availability
Authors: Nikhil Sagar Miriyala
Published: February 2025

Modern event-driven architectures rely on frameworks like Apache Kafka to enable real-time asynchronous processing. However, ensuring high availability across distributed systems, particularly in a multi-region environment, poses challenges such as avoiding duplication of data and achieving seamless failover with minimal manual intervention. This paper proposes a robust solution that leverages AWS Managed Streaming for Apache Kafka (MSK) to design an active-active highly available system. By implementing a smart consumer-based idempotent mechanism with a globally shared database and message-level UUIDs, the system ensures zero message duplication while maintaining fault tolerance. This design effectively minimizes latency, supports system resilience, and addresses the challenges of distributed event streaming systems. Practical considerations, including scalability, failure recovery, and latency optimization, are also discussed to provide a comprehensive guide to the deployment of resilient event-driven architectures in cloud-based infrastructures.
AI-Based Phishing Attack Detection And Prevention Using Natural Language Processing (NLP)
Authors: Sospeter Birir Kipchirchir , Odoyo Wilfred
Published: February 2025

Phishing attacks remain one of the most prevalent and damaging cybersecurity threats, targeting users across various communication channels such as email, social media, and SMS. Traditional phishing detection systems are often limited to email and rely on static rule-based filtering or keyword matching, making them ineffective against evolving phishing tactics. This project proposes an innovative solution that utilizes Artificial Intelligence (AI) and Natural Language Processing (NLP) to create a real-time phishing attack detection and prevention system. By analyzing the contextual language of messages across multiple platforms, the system can detect and block phishing attempts with high accuracy. The system extracts important linguistic features such as urgency, emotional tone, and anomalous patterns within text, and applies machine learning algorithms—such as Random Forest, Support Vector Machines (SVM), and deep learning models like Long Short-Term Memory Networks (LSTM)—for classification. Additionally, a feedback loop is integrated to allow the system to adapt and improve over time through active learning, ensuring the detection system evolves alongside emerging phishing techniques. This AI-based solution extends beyond traditional email phishing detection by incorporating multiple channels, including SMS and social media platforms, making it a versatile tool for individuals and businesses. The system offers automated prevention actions, such as flagging suspicious messages and alerting users, thus providing a robust defense against phishing attacks in real-time. The project's implementation aims to fill the market gap in comprehensive, multi-channel phishing detection and contribute to the growing demand for intelligent and adaptive cybersecurity solutions.

Authors:   V. N. Karazin Kharkiv National University, Khanova Olena V. , Shynkarenko Oleksii S. ,   V. N. Karazin Kharkiv National University
Published: February 2025

The article is aimed at studying the state of the Internet in African countries, analyzing the experience of its use depending on the level of development of countries, as well as forming prospects for the growth of the introduction of information and communication technologies (ICT) in the context of significant infrastructure challenges, in particular access to electricity. The state of electricity supply in urban and rural areas of African countries, which is a basic condition for the introduction of modern ICT and digital transformation, has been analyzed. A comparative analysis of structural changes in access to electricity for the period 2017–2023 for 43 countries of the African region was carried out. It is found that most countries demonstrate positive dynamics of access to electricity, but some countries remain significantly backward due to economic instability, conflicts and destruction of infrastructure. A forecasting of the prospects for 3G and 4G network coverage, which are key elements of digital infrastructure, is carried out. It is identified that by 2026 the full coverage of the 3G network in Africa may reach 99.41%, which will create prerequisites for the further introduction of 4G. Next, the gradation of African countries in terms of the level of informatization and digital transformation has been carried out. The group with a high level of informatization includes such countries as South African Republic, Egypt, Morocco, Kenya, Tunisia, Algeria, which demonstrate a high level of access to the Internet and significant structural shifts in the development of ICTs. The countries with an average level of digital integration, such as Nigeria, Senegal, Tanzania, Rwanda, Zambia, need further investments in infrastructure. The least developed countries, which are Chad, Somalia, Burkina Faso, face critical problems of access to electricity and low levels of informatization. A number of scientific and practical recommendations are formulated, which provide for the use of alternative energy sources, attracting international investments, introducing educational programs on digital literacy for young people, creating conditions for the development of local startups in the field of ICT and energy. Particular attention is paid to the role of the African Union in coordinating the efforts of the countries of the region to bridge the digital divide, ensure sustainable development and integrate Africa into the global digital economy.

La administración gubernamental bajó el valor de la empresa a un 30 % de su valor real. Después cambió el método de valuación, de valor de uso a costos específicos, incrementando el valor de la empresa sin inversión. Una estrategia para endeudar a AHMSA, y posteriormente incrementar el valor de esta es el traspaso de las empresas subsidiarias a la nueva tenedora, Grupo Acerero del Norte (GAN); a partir de 1993, GAN vende a AHMSA estas mismas empresas considerando el método de unión de negocios. A partir de 1992 se inicia el apalancamiento externo llegando a niveles insostenibles. Siendo necesaria la capitalización de las deudas o inversión atrapada en la suspensión de pagos ya que es una empresa operativamente viable y auto sostenible.

En este trabajo se hace un estudio de los factores que influyen en el comportamiento de los consumidores ecológicos tales como anuncios, información de precios, empaques, aspecto del producto, entre otros. Se analiza la tendencia mundial socio ambiental en la forma en que el producto se fabrica, comercializa y consume, para hacer frente al impacto ambiental que tiene su ciclo de vida. Posteriormente, se examinan las pautas y características que presenta la mercadotecnia social en aspectos ambientales. El enfoque principal para el estudio que se utilizó para investigación del comportamiento fue el interpretativo, utilizando teorías y métodos de la antropología cultural para desarrollar una comprensión más profunda del consumo y sus significados.

Michoacán es el primer productor frutícola en el país y las exportaciones de estos productos tienen una importante participación en la balanza comercial del estado. Sin embargo, con la apertura de los mercados internacionales estas empresas se enfrentan a exigencias restrictivas justificadas por los problemas ambientales y por consecuencia un incremento de políticas ambientales. Por otro lado se enfrentan además a las presiones de los diferentes agentes en términos sociales, en que las empresas no sólo sean generadores de empleos, sino que contribuyan al desarrollo de las comunidades en donde realizan sus operaciones.
Para explorar el manejo de las variables ambientales y sociales de las empresas agroexportadoras michoacanas, se realizó un diagnostico del desempeño ambiental y de responsabilidad social a 69 empresas durante el periodo Enero-Marzo de 2009. Se elaboró un índice (Índice de Desempeño Ambiental y Responsabilidad Social) a partir del Análisis Jerárquico Analítico (AHP) obteniendo como resultados que 72% de las empresas analizadas tienen un bajo desempeño ambiental.

El presente trabajo plantea la posibilidad de que la relación entre gestión por competencias como causante de los resultados empresariales pueda ser al revés, es decir, que produzca una causalidad inversa, de manera que sean las empresas con buenos resultados empresariales las que pueden permitirse implantar un sistema de gestión por competencias. En este sentido, las principales conclusiones de este trabajo se refieren a la existencia de una relación importante entre la capacidad económica de las empresas españolas y la implantación de la gestión por competencias de acuerdo a los distintos contrastes llevados a cabo con los estadísticos del )2, tablas de contingencia, prueba binomial y de diferencia de proporciones a partir del valor de Z.

En principio, la estructura conceptual de competencias se ve representada por Boyatzis (1982): “Características subyacentes que están casualmente relacionadas con la actuación efectiva o superior en un puesto de trabajo”. Una acepción más integral y relacional es la Levy-Leboyer quien establece que: 'Un conjunto de conductas organizadas, en el seno de una estructura mental, también organizada y relativamente estable y movilizable cuando es preciso”.
Woodrufe (1993) define el termino competency como: 'El conjunto de patrones de comportamiento que una persona necesita para desempeñar un puesto de trabajo de manera que lleve a cabo funciones y tareas correspondientes con competencia”. La definición de este autor parte de un análisis que realiza a los términos “competency” y “competence”.
Prieto (1997:8-9) considera el concepto de “competencia” se presta a múltiples interpretaciones. Sus acepciones de acuerdo a: autoridad, capacitación, cualificación, etc.
La conceptualización del término “competencia” en la forma que ha sido abordada en la literatura, revela pues la existencia de confusiones considerando algunas razones que incluirían las diferencias culturales entre los países, las empresas y en la dimensión política.
Para definir el término “Competencias” o “Competencia” hay una gran complejidad por los diversos enfoques del citado concepto, como el empresarial, formación académica y de estándares profesionales. Debido a ello, este trabajo sólo ha tenido el propósito de aportar datos conceptuales en aras de clarificar lo más posible su significado.
UNA APROXIMACIÓN TEÓRICA, METODOLÓGICA Y CONCEPTUAL A LOS MERCADOS DE DERIVADOS

Los instrumentos financieros derivados son en la actualidad instrumentos comunes y hasta cierto punto centrales en las actividades diarias de muchos mercados financieros todos los días alrededor del mundo, pero aun así, no son todavía muy bien comprendidos fuera del círculo de los iniciados que constituyen a los participantes activos en dichos mercados.
En consecuencia, el presente artículo tiene como principal objetivo el explicar el funcionamiento de los mercados de derivados a todos aquellos que no estén familiarizados con ellos; o bien, que aunque tal vez sí estén un poco familiarizados con ellos, requieran reforzar sus conocimientos en el tema. La idea clave del artículo es la de demostrar que los mercados de derivados ayudan a lograr una gestión de riesgo efectiva y eficiente.
El trabajo hace énfasis en los mercados de derivados que negocian con los siguientes subyacentes: tasas de interés y tipos de cambio, es decir, con activos financieros, pero los principios bajo los cuales operan pueden ser aplicados a cualquier otro tipo de activo subyacente puesto que los mencionados principios son prácticamente idénticos.
En síntesis, los objetivos del presente artículo son los siguientes:

Establecer las características de los principales tipos de derivados: forwards, futuros, swaps y opciones.
Describir las características comunes que hacen atractivos estos instrumentos financieros a los usuarios de los mercados financieros.
Debatir acerca de la cuestión de la gestión del riesgo con los instrumentos financieros derivados, tan de boga en estos días; esto es, si los derivados son tan útiles para la gestión eficiente del riesgo, ¿por qué se han estado experimentando en los últimos meses un número tan importante de quiebras de firmas y empresas tanto del sector financiero como de otros sectores, debido, entre otras causas, al comercio efectuado con los derivados?
Caracterizar qué tipo de información se puede obtener a partir del proceso de fijación de precios con instrumentos financieros derivados.
