The implementation of digital technologies and the rapid transition to Industry 4.0 have influenced the speed of information exchange, thereby increasing uncertainty and the likelihood of making ineffective management decisions. At the same time, to avoid entropy in managing a manufacturing enterprise, a transformation of tools, methodologies, procedures, and standards is necessary to ensure the company’s sustainable development. One way to increase the reliability of a company’s operations in conditions of uncertainty and risk can be the organization of a risk management and internal control system (RMIC). RMIC is defined as a set of organizational measures, methodologies, procedures, norms of corporate culture and actions aimed at achieving an optimal balance between value growth, profitability, and risks to ensure financial stability, efficient business operations, asset preservation, compliance with laws, statutes, and internal documents, timely preparation of accurate reports. Furthermore, in uncertain conditions, it is advisable to consider RMIC in the context of an integrated business-process system because, to ensure reasonable confidence in achieving the company’s goals in operational activities, reporting, and fulfilling all obligations, it implies organizing risk management primarily at the process and operational (transactional) levels, and aims at increasing the efficiency of the company’s activities as a result of integrating risk management with strategic planning processes, business planning, and decision-making. The article presents the conceptual foundations of a production enterprise’s RMIC. Key performance indicators, internal control procedures, key risk indicators, the structure of elements and system operation algorithms are justified. Theoretical conclusions of the authors are based on the results obtained within the framework of testing the proposed RMIC model for the business process “Construction Supervision Organization for Gazprom Customers”. It is concluded that, to ensure confidence in achieving goals at a production enterprise, RMIC should be developed, implemented, and continuously developed. Risk management and internal control processes should be carried out using best practices, principles, and methods. In this case, the risk management measures taken by the company will allow risks to be kept within acceptable limits and provide shareholders with sufficient guarantees to achieve their goals and objectives.

The need to solve strategic problems related to the ESG agenda and the technological independence of the Russian economy, the key mechanism to tackle which is the introduction of the best available technologies, have updated the need for this study of the effectiveness of an integrated approach to stimulate their implementation in the production processes of oil and gas companies. The integrated approach to the introduction of the best available technologies in the Russian practice and the effectiveness of existing financial and tax incentive mechanisms were analyzed. Empirical and economic-statistical methods were used. The results of the study show that financial and tax benefits (such as fines for excessive combustion of associated petroleum gas, subsidizing the cost recovery on loans and coupon income from the federal budget on issued bonds in order to implement projects with the introduction of the best available technologies increasing the coefficient to the depreciation rate for purchased equipment, investment tax deduction) have a positive effect. They form a complex interconnected system of state influence on economic entities in accordance with national interests and strategic objectives, which is based on the carrot and stick principle. The current system of financial and tax incentives is an indirect trigger for mergers and acquisitions in the oil and gas industry and its further oligopolization, since it has a differentiated character conditioned by the advantage of large companies in the possibility of using preferences due to the established conditions for their application. Therefore, further adjustment is necessary taking into account the possibility of application for small and medium-sized independent oil and gas companies. The provisions of tax legislation were adopted under the influence of strategic objectives taking into account two main factors: the utilization of production capacities after the downtime of the post-Soviet decade and the solution of problems resulted from the ratification of international agreements, in particular the Kyoto Protocol of 1996, which did not put the country’s technological independence as an absolute priority. Currently, the Russian economy should be precisely based on technological independency as the basis for sustainable long-term socio-economic development and the need to achieve tougher global international imperatives in terms of environmental protection under sanctions pressure. As a result, there is a need to review the existing preferences in order to adjust them and strengthen their interconnection taking into account the results of further research in terms of the cumulative effect of the implemented organizational and economic mechanisms that contribute to achieving carbon neutrality.

The day-to-day activities carried out at the mechanic workshop like panel beating, welding, and automobile battery servicing may result in high amounts of heavy metals in the soil near mechanic workshops. Spent engine oils also emit a huge number of toxic metals, when disposed of on the floor at workshops, they settle on soil and are absorbed into nearby trees and plants. Therefore, making the tree parts and fruits at mechanic workshops prone to attack by heavy metals. This work is focused on testing if the presence of heavy metals would have adverse effects on the tree parts (roots, shoots, upper leaves, lower leaves) and fruits of mechanic workshops. A mechanic village in Abeokuta, Ogun State was chosen as the case study. The tree parts were oven-dried, ground, digested, and taken for analysis using AAS. Zinc (Zn), Lead (Pb), and Mercury (Hg) were found in higher amounts than the recommended allowable limits by WHO/FAO. Results show that the upper bark had the highest heavy metal concentration. In general, the tested heavy metals were recognized in the order: Zinc (Zn) > Lead (Pb) > Mercury (Hg) > Nickel (Ni) > Manganese (Mn) > Iron (Fe) > Copper (Cu). It is recommended that mechanic villages should be sited far from residential areas. Remediation of polluted soil should be encouraged. Phytoremediation was suggested to be the best method for reducing the concentration of heavy metal in the soils and tree parts at mechanic workshops. Continuous education and training should be provided for automobile repairers/ mechanics, emphasizing the environmental implications of their poor occupational waste management and the dangers of eating fruits and taking herbs from trees planted in workshops.

Konsep wasiat aset digital merupakan implikasi baru yang dilihat berlaku dari penggunaan dan kebergantungan teknologi komunikasi oleh pengguna di seluruh dunia. Konsep ini penting dalam pengurusan memori dan data digital bagi pengguna untuk menghadapi kematian dalam abad ke-21 ini. Hal ini berlaku apabila perkembangan teknologi komunikasi seperti telefon pintar telah melalui transformasi sebagai alat pendigitalan data yang dikonseptualisasi sebagai memobilia. Pengaruhnya menyebabkan pembentukan memori dan data digital yang boleh dikategori sebagai aset digital. Aset digital merangkumi data, maklumat, memori dan platform digital yang mempunyai nilai privasi, sensitiviti, sentimental dan monetari. Namun, tanpa pemindahan hak digital, aset digital yang bernilai ini tidak boleh diwarisi dan dilindungi oleh pewarisnya selepas seseorang pengguna meninggal dunia kelak. Oleh sebab kematian tidak boleh dielak dan diramalkan, maka kesedaran konsep wasiat aset digital sebagai sistem pewarisan bagi pengurusan aset digital penting kepada golongan belia. Kepentingan ini wujud disebabkan belia merupakan golongan tertinggi yang bergantung kepada penggunaan telefon pintar di Malaysia. Sehubungan itu, kajian ini bertujuan menilai hubungan memobilia, kebergantungan telefon pintar dan aset digital terhadap kesedaran wasiat aset digital dalam kalangan belia. Kaedah survei dilakukan terhadap 395 belia di Selangor yang dipilih melalui pensampelan bertujuan. Data survei dianalisis menggunakan prosedur sistematik Partial Least Square Structural Equation Modelling (PLS-SEM). Hasil kajian menunjukkan memobilia mempunyai hubungan yang positif dan signifikan terhadap kebergantungan telefon pintar dan aset digital, namun tidak signifikan terhadap kesedaran wasiat aset digital. Hasil kajian ini memberi implikasi kepada kesedaran belia dalam melindungi aset digital menerusi pemindahan hak digital yang berlaku melalui konsep wasiat aset digital.

This study aims to examine the reporting of the Israeli aggression towards in the Indonesian newspaper Republika during the years 1999 and 2021, with a contextual reference to the 2024 Gaza genocide. The reports were selected through purposive sampling, focusing on direct coverage from both 1999 and 2021. Additionally, interviews were conducted with members of Republika's editorial team. Using Entman’s framing theory as well as Shoemaker and Reese’s Hierarchy of Influences model, the research identifies notable differences in news framing between the two periods. In 1999, the coverage in Republika largely emphasised political support from prominent figures, both in Indonesia and internationally, advocating for the defence of Palestine. In contrast, the 2021 coverage highlighted support from civil society, including athletes and celebrities. Differences are also evident across several levels of the Hierarchy of Influences model, with the media routine, organisational, and ideological levels being the most prominent. In 1999, Republika’s reporting on the Israeli-Palestinian conflict in the international section was relatively independent, focusing primarily on political issues. By 2021, however, the reporting followed a compartmentalised model, where one section complemented and connected with others. Despite the differences in time and ownership, Republika's stance on the Israeli-Palestinian conflict remained consistent. The newspaper continues to assert that the Palestinian people must be defended, a position shaped by its Muslim readership, who maintain a strong psychological connection with Palestinian Muslims. Keywords: Framing, the Israeli-Palestinian conflict, media ownership, the influence of mass media hierarchy, Republika.

From China to Malaysia: Understanding The Cultural and Economic Dynamics of Imported Chinese Films
Authors:   Xiamen University Malaysia, Wang Changsong
Published: October 2024

The connection between China’s diplomatic engagements abroad and its trans-border film trade holds considerable importance. Inherent in this dynamic is cross-cultural interaction and inter-cultural communication. Malaysia’s support for China’s Belt and Road Initiative has fostering a growing cultural exchange, particularly through the trade of Chinese films, some of which have aschieved significant box office earning success in Malaysia. Despite occasional media attention, there is a notable lack of scholarly literature addressing the impact of these films on Malaysian audiences. This study examines the cinematic consumption of the films imported from China by Malaysian distributors for exhibition to its cinemagoers, using Song Hwee Lim’s framework of conceptualization of transnational cinema. It seeks to better understand the phenomenon of the imported Chinese films for audience appeal, cultural influence and impact on box-office earnings. By collecting and analyzing relevant data from distributors through in-depth interviews with their representatives, this study identifies the approaches of film promotion and marketing activities that are reshaping the cultural experience of filmic storytelling in the Malaysian context. The implications of this study extend beyond film distribution, offering insights into how transnational cinema can shape cultural narratives and influence the cultural landscape in a globalized context. By examining the interplay between Chinese films and Malaysian audiences, the research highlights the role of transnational cinema in fostering cultural exchange and understanding, as well as its potential to impact the future direction of filmic storytelling within a multicultural society. Keywords: Transnational cinema, Chinese film, Malaysian cinema, film distribution, cultural trade.

Published: October 2024

The research will focus on the West Jakarta Health Service's Communication Strategy for Disseminating the COVID-19 Vaccine. This research is inspired by the concern that the Jakarta COVID-19 vaccination achievement remains below target, particularly for the elderly, at 64.85 percent for the first dose and 58.44 percent for the second dose in October 2021. There are many obstacles such as hoax news and low public knowledge about vaccines. This research focuses on how to examine the Jakarta Health Office's communication strategy in inviting people to implement COVID-19 immunization. This research will expand on health communication concepts and theories by employing Push, Pull, and Pass communication tactics. A variety of doctors, and health professionals were interviewed for this study. The study results show that the push approach is implemented by opening direct vaccine centres, pulling through persuasively, door prizes, basic food packages, cooperation cross-sectors, and passes with public figure testimonials. The job of Dasawisma cadres is critical because they are the ones who directly persuade the people in simple languages like Javanese and Sundanese. The community also trusts the Dasawisma cadres because they are previously acquainted. The City of West Jakarta achieved 98% of the first dosage of the vaccination, and 65% dosage 2nd in December 2022. Keywords: Health communication, vaccine, communication strategies, COVID-19, Dasawisma.

Since the Movement Control Order (MCO) in 2020, Malaysia's Ministry of Education (MOE) has recommended online learning sessions. Traditional teaching methods need to be replaced with more modern approaches. This change allows students to participate in distance learning, making online learning more widely accepted in education. However, the challenges of online communication have intensified due to the pandemic. Some teachers may find the complexity of online platforms an obstacle and may use this as an excuse to avoid using technology. Another issue is the lack of computer proficiency, which can create a fear of technology. Additionally, the convenience of learning from any location at any time should be considered. Previous studies have shown that user motivation plays a crucial role in accepting technology. This study aims to develop an instrument that measures teachers’ acceptance of online learning based on the Technology Acceptance Model (TAM). The article will focus on developing a questionnaire to assess the following variables: teacher’s Perceived Usefulness, Perceived Convenience, Perceived Ease of Use, Attitude, Intention to Use, and Usage Behaviour in accepting technology. The study used a quantitative approach. The pilot test was conducted on the instrument for 40 secondary school teachers in Perak. The data were analysed both descriptively and inferentially. The reliability and validity results were significant and are expected to aid future researchers in developing better assessment tools. Keywords: Instrument development, questionnaire, Technology Acceptance Model, teachers’ acceptance, online education.
AN EQUIVALENCE RELATION ARISING FROM MULTIPLICATION OF QUANTUM INTEGERS
Authors: Nguyen Lan
Published: October 2024

In the paper [5], we conjecture that the relation arising from multiplication of quantum integers and the problem of finding a set of criteria for extending the support bases of solutions of a functional equation arising from multiplication of quantum integers, which is described by Nathanson in [2] as Problem 3, is an equivalence relation. We show in [5] that the answer is affirmative in the case where the fields of coefficients of these solutions are . In this paper, we prove that the answer is in fact also affirmative for all fields of characteristic zero. As a consequence of this result, we explain how it simplifies in several important ways the criteria for extension of support bases of solutions of the above functional equation.
On the Suboptimal Solution of the Speed-In-Action Problem for a Linear Discrete System in the Case of Asymmetric Control Constraints
Authors: Podgornaya V.M.
Published: October 2024

The paper considers a linear discrete system with bounded control. The speed-in-action problem is solved for the system, that is, it is required to construct a control process that transfers the system from the initial state to the origin in a minimum number of steps. If the set of acceptable control values has a superellipse structure, then the problem of calculating optimal control can be reduced to solving a system of algebraic equations. A superellipsoidal approximation method has been developed for sets of arbitrary structure, and the case of asymmetric sets has been considered. Examples are given.

En el nombre de Dios… y la República. Los católicos antifranquistas y la Santa Sede en la larga posguerra (1939-‍1953)
Authors: Rodríguez Lago José Ramón
Published: October 2024

Este artículo aborda las relaciones, desde el final de la Guerra Civil española a la aprobación del Concordato y de los Pactos de Madrid, entre la Santa Sede y los católicos españoles que se habían manifestado previamente en favor del bando republicano. El estudio de la documentación del pontificado de Pío XII accesible en los archivos vaticanos y romanos, la consultada en archivos estadounidenses y la de algunos archivos de titularidad eclesiástica en España permite afrontar cuestiones como el funcionamiento, la dimensión y el alcance de la agencia diplomática desarrollada por la curia vaticana ante la España de Franco y la del exilio, la labor asistencial y espiritual entre los refugiados españoles o la actuación respecto los presos políticos y los sentenciados a muerte. La atención al gobierno multinivel de las diversas agencias pontificias que participaron en tales procesos permite constatar cómo la acción desarrollada por Montini mediante la Pontificia Commissione di Assistenza ai Profughi (PCA) y la sección de Secretaría de Estado encargada de velar por la agenda católica en los organismos internacionales se vio superada por el cariz de los informes presentados por los nuncios Cicognani y Roncalli o los subordinados de Domenico Tardini. Las medidas contra militantes y clérigos católicos opuestos al régimen de Franco contaron en la mayor parte de las ocasiones con la aceptación, más o menos entusiasta, de una Santa Sede más influida por los intereses de la Realpolitik que por los principios humanitarios o los postulados de su misión espiritual.
Tratando de hacerse fascistas… Falange y el personal político franquista en provincias. Parafascismo, culturas políticas e hibridaciones, 1933-‍1945
Authors: Rodríguez Barreira Óscar
Published: October 2024

Ofrecemos una revisión crítica al problema del fascismo y el poder local bajo el franquismo. En los últimos años se ha consolidado una definición del poder local franquista como un poder local parafascista o fascistizado. No obstante, hay un debate sobre la continuidad o ruptura del personal político. Esa aproximación y debate impiden, en gran medida, que se atienda a sus culturas políticas, a su modo de ser y estar en el mundo. Además, pretende mostrar caminos para corregir esas carencias. En primer lugar, realizamos una revisión bibliográfica sobre el debate de los poderes locales bajo el franquismo. Luego, señalamos los argumentos principales de las nuevas aportaciones al estudio de los cuadros políticos intermedios del franquismo. Finalmente, proponemos una línea de trabajo que ayude a comprender aspectos que, en gran medida, han sido pasados por alto, como el papel del falangismo de primera hora en el ámbito local de la dictadura. Este acercamiento matizará de azul un cuadro hasta ahora quizás algo tenue.
¿Existe una historia social de la guerra civil de 1936 en el siglo XXI?
Authors: Ledesma José Luis
Published: October 2024

Este artículo propone un recorrido por la presencia de la historia social en la producción historiográfica del siglo XXI sobre la guerra civil española de 1936-‍1939. Aunque es evidente la heterogeneidad y polifonía de ese enfoque, si convenimos en un mínimo común denominador de temas de estudio, métodos y objetivos es posible dibujar una cierta evolución. Después de haber disfrutado de un indudable protagonismo, y a la par que se abría a las propuestas y modos de la historia cultural, desde finales del siglo XX este enfoque perdió presencia, y parecía que potencia explicativa, en la historiografía sobre la guerra del 36. Sin embargo, ni fue un súbito giro copernicano ni supuso las exequias del enfoque ni se debió únicamente a sus límites epistemológicos, puesto que se inscribía en desplazamientos más amplios en el campo historiográfico y en el mundo del cambio de milenio. De hecho, la bibliografía más reciente muestra cómo la investigación de esa guerra y de los orígenes del franquismo vuelve a abrirse, con otras miradas, a los objetos de estudio y utillaje asociados a una renovada historia social.

Published: October 2024

Problem statement. Investigation of correlation properties of complete code of binary spread spectrum phase-shift keyed signals as the limiting case of large systems is a topical task for building large systems of binary spread spectrum phase-shift keyed signals with polarization coding with optimal correlation properties. Also, this task is of independent academic interest due to the fact that the alphabet of symbols for these signals lacks multicasting properties unlike the familiar cases of complete codes of spread spectrum phase-shift keyed signals. Objective. To accurately define the distribution laws as well as the moments about zero and the mean for the n-th order of presented values of aperiodic and periodic correlation functions of the complete code of binary spread spectrum phase-shift keyed signals with polarization coding. To offer approximations of accurate distribution laws suitable for engineering applications. Results. The accurate distribution laws for presented values of aperiodic and periodic correlation functions of the complete code of binary spread spectrum phase-shift keyed signals with polarization coding were found in the form of the related distribution series. The analytic expressions for the n-th order of presented values of these functions for the complete code of the specified signals were assigned. The calculation example for the distribution series of presented values of aperiodic and periodic correlation functions for the complete code of the specified signals with the length of vector code sequences N=4 was given. The values of the relative frequencies of the correlation functions values for this case were found by the means of direct computing and their exact match with the corresponding predicted probability values was demonstrated. The approximations of the accurate distribution laws were given: for periodic correlation functions case – by Gaussian probability density, and for the aperiodic functions case – by the Pearson curve of VII type. Practical relevance. The found accurate laws for presented values of aperiodic and periodic correlation functions of the complete code of binary spread spectrum phase-shift keyed signals with polarization coding and their approximations allow to assess the correlation properties of large systems of such signals.

Published: October 2024

A rectangular waveguide with a dielectric plate located in the E-plane is the basic element of devices for microwave heat treatment of sheet materials. In this regard, it is relevant to study the processes of propagation and transformation of electromagnetic waves in such a system. The purpose of the work is to study the influence of the transformation of the electromagnetic field in the air medium of a rectangular waveguide in the zone of propagation of the slow wave H10 on the distribution of electric field energy in the dominant wavelength range and determining the wavelength, at which its maximum value is reached. The range properties of the intrinsic electrodynamic parameters and the field structure of a rectangular waveguide with a dielectric plate located in the E-plane in the middle of its wide wall have been studied. The wavelength at which the maximum energy level of the electric field in the dielectric plate is achieved is determined. The results obtained can be used in the design of microwave heating devices for dielectric materials.

Authors: Khoroshailova M.V. , Kuznetsov А.V. , Demikhova A.S.
Published: October 2024

Problem statement. All known methods for determining the parameters of the encrypted code are based on known types of channel encoding and encryption, but the scrambling code data received by the uncoordinated communication parties is unknown, therefore it is necessary to analyze whether the outgoing signal is encoded, and which encryption method is adopted, contributing to further parameter determination. Goal. Development of a methodology for determining the types of encryption of linear block codes by combining correlation features and convolutional neural networks. Results. The simulation results show that compared with the traditional feature detection method, this method, based on a convolutional neural network and long short-term memory, has a better recognition speed at BER and can recognize the type of encryption of linear block code in BER and noise conditions. Practical significance. The identification of the encryption code parameters is used to subsequently determine the parameters of the encoder and has significant practical engineering value. The work was carried out with the financial support of the Ministry of Science and Higher Education of the Russian Federation within the framework of the state assignment "youth laboratory" No. FZGM-2024-0003.

Authors: Zhuravlev A.V. , Kiryushkin V.V. , Babusenko S.I. , Markin V.G.
Published: October 2024

Formulation of the problem. The main means of protecting the navigation equipment of consumers of the global navigation satellite system from intentional interference is the spatial selection of information signals using an adaptive antenna array. In this case, the weight coefficients of the antenna array must be calculated without using information about the directions to the signal and interference sources. To calculate the weighting coefficients, the eigenvectors of the correlation matrix of the input signals of the antenna array, obtained during its spectral decomposition, can be used. Purpose. The purpose of this work is to present an algorithm for spatial interference compensation based on the spectral decomposition of the correlation matrix of the input signals of an adaptive antenna array and to evaluate its effectiveness. Results. An algorithm for spatial compensation of interference in a four-element adaptive antenna array is presented, based on the spectral decomposition of the correlation matrix of its input signals. The effectiveness of the presented algorithm was assessed using computer simulation. It was found that when the input of the antenna array was exposed to three interferences with an amplitude 500-2000 times greater than the amplitude of the information signal, the level of interference at the output of the antenna array decreased by more than 4000 times. Practical significance. The results obtained can be used in the development of a compensator for interference signals of navigation equipment of consumers of the global navigation satellite system.

Formulation of the problem. The method of delivering radio jamming transmitters to the area where a radio-electronic device is located, based on dropping transmitters from an unmanned aerial vehicle, is characterized by a number of disadvantages: high complexity of the equipment and, accordingly, the high cost of the UAV; low efficiency of radio interference transmitters in suppressing ground-based radio electronics of satellite radio communication and radio navigation systems. Purpose. Consider the possibility of increasing the efficiency of radio-electronic suppression of ground-based radio electronics of satellite radio communication and radio navigation systems by autonomous radio jamming transmitters delivered to the work area using UAVs, while reducing the complexity of the equipment and the cost of UAVs - carriers of radio jamming transmitters. Results. A delivery system for radio interference transmitters is proposed. The system uses an uncontrolled free aerostat (balloon) filled with gas as a UAV. The volume of gas depends on the given flight altitude. The balloon, together with the transmitter and battery, is launched from a starting position placed on the earth's surface, taking into account the known direction of the wind and the known location of the suppressed weapon. The balloon is delivered to the electronic jamming work zone by moving air masses. The calculations showed that the use of the proposed system provides a gain in the required transmitter EIRP of at least 7 dB compared to a ground-based transmitter. To suppress a Starlink user terminal at a range of up to 4 km, a transmitter with an EIRP of no more than 13 dBW (20 W) is required. Practical significance. The results obtained can be used to increase the efficiency of electronic jamming of ground-based satellite radio communication and radio navigation systems.

Formulation of the problem. A promising area of research in the field of functioning of navigation equipment for consumers of global navigation satellite signals is the development of protection of consumer equipment from the effects of simulated interference. The high availability of navigation signals of the open segment entails the threat of covert influence on consumer equipment. To date, protection measures against covert interference have been developed and applied for multi-channel consumer equipment with high computing capabilities. However, for low-channel consumer equipment, the development of such protection measures is required, for which it is necessary to determine the probabilistic characteristics of the functioning of the equipment under study under the influence of signal-like interference. Purpose. Determination of the probabilistic characteristics of the operation of multichannel navigation equipment for consumers of global navigation satellite signals in a complex interference environment. Results. A model of the functioning of consumer navigation equipment is constructed and mathematically described, the probabilistic characteristics of the functioning of consumer equipment in a complex interference environment are calculated, and the coefficient of effectiveness of signal-like interference is introduced. Practical significance. The results can be used by specialists in the field of satellite radio navigation in the development of protection systems against covert intentional exposure.
Method for controlling the radiation pattern of an underground radiation antenna

Currently, communication and signaling means of underground structures are implemented by wire lines. In addition, radio communications of various frequency ranges are used, operating within line of sight and having the disadvantage of interrupting radio communications in emergency situations. Low-speed broadcast systems using ultra-low frequencies are also used. This work shows the possibility of using subsurface georadar technology to organize a faster circular warning system for underground structures. Existing GPR instruments using ultra-wideband pulses in the 1 to 50 MHz band reach depths of several hundred meters. In this case, control of the radiation pattern of the underground radiation antenna is possible both in the horizontal and azimuthal planes. Modern methods of controlling antenna-feeder devices used in georadar are shown, allowing to improve user qualities for various applications. With the development of these methods, additional areas of application of these devices appear: in underground radio communication systems, for identifying low-contrast objects, for ground penetrating radar from aircraft. Based on the method for controlling the directional pattern of underground radiation antennas in the horizontal plane for stationary or specialized devices, a new method has been developed to control the main lobe of the directional pattern in the azimuthal plane of the transmitting antenna. A method has been proposed for controlling the radiation pattern in various technical implementations, which allows changing the position of the radiation pattern both discretely and smoothly. Examples of using the developed method for controlling the radiation pattern of an underground radiation antenna for the implementation of geophysical instruments of various types have been shown. The possibilities of locating underground radiation antennas in various soils have been proposed when using them in circular warning systems for underground structures.

Choosing the right software development methodology can play a key role in making a project successful. Depending on the chosen methodology, it is possible to reduce product delivery times, development costs, manage uncertainty and risks, improve quality and user satisfaction, and provide more detailed control over the project. Despite the importance of this task, the choice of the most appropriate methodology for a particular project is difficult due to the large number of evaluation criteria, the lack of sufficient literature on this issue and the low level of formalization of the process, when the choice of methodology is made only on the basis of the previous experience of the project manager. The purpose of the work is to increase the efficiency of the processes of substantiation and selection of software development methodologies for specific projects. The article discusses the main well-known life cycle models and software development methodologies. An analysis of methods and criteria for classifying methodologies was carried out, and the shortcomings of existing classifications were identified. A new multi-criteria hierarchical classification is proposed, offering a more complete and broader distribution of life cycle models and software development methodologies across classes. A review of existing methodologies, an analysis of known classification methods and their shortcomings, the methodologies classification proposed by the authors will help project managers more reasonably choose development methodologies and reduce risks in the process of managing software projects.
