The work of determining the value of information assets across the entire organization is both the most significant and the most difficult. It is the assessment of information assets that will allow the head of the IS department to choose the main areas of activity to ensure information security. First of all, when carrying out this procedure, it is necessary to obtain information about the organization's assets, which are used in its daily activities. The value of the asset is expressed by the amount of losses that the organization suffers in the event of a security breach of the asset.
A threat has the potential to harm assets such as information, processes and systems, and therefore the organization itself. Threats can be of various origins: natural, man-made or anthropogenic; can be intentional or accidental. All sources of threats to assets must be taken into account during identification.  The purpose of the process of identification and assessment of the importance of information assets is to obtain importance values for the selected assets of the organization. The result of this process is important both for risk assessment and for understanding the need for IS measures.
In this article, an analysis of international and domestic standards and practices in the field of identification and assessment of the importance of the organization's information assets was carried out, as well as approaches and methods of identification and assessment of the importance of the organization's information assets in the assessment of information security risks were considered. Based on the results of the performed analysis, a method of identification and assessment of the importance of the organization's information assets was developed.
As a result of the work, the implementation of a more advanced approach to risk management and, accordingly, information security was achieved.

Material strength criteria are fundamental to understanding the durability and failure limits of materials under various stresses and loading conditions. Different models help predict material behavior under complex conditions, including uniaxial, biaxial, and multiaxial stresses. Among the widely used criteria, the von Mises criterion is essential in predicting yielding in ductile materials, suggesting that yielding occurs when the second deviatoric stress invariant reaches a critical value. The Pisarenko–Lebedev criterion expands on this, accounting for hydrostatic stresses, which is especially useful in brittle materials. The Willam–Warnke criterion is widely applied to concrete and similar materials to predict behavior under triaxial states of stress. The Drucker–Prager criterion generalizes the Mohr-Coulomb model by incorporating a continuous yield surface, making it particularly applicable for soils and other pressure-sensitive materials. Bazant’s theory contributes to understanding concrete's behavior, especially regarding cracking and creep in quasi-brittle materials, a valuable extension to other yield criteria In composites, criteria such as Tsai–Hill, Tsai–Wu, Hashin, and LaRC (LaRC being NASA's laminate analysis criterion) allow for precise predictions of material failure under combined stress states, taking anisotropy and unique composite material responses into account. Hoffman’s criterion further modifies Hill’s theory, addressing the need for additional precision in anisotropic materials Additionally, the Kunze and Goldenblat–Kopnov criteria contribute to the realm of composite materials by providing criteria for different types of failure modes under multi-axial loads, vital for high-performance applications. The Norris criterion also emphasizes composite failure but is particularly useful for cases with complex stress states. Lastly, Puck’s criterion is specialized for fiber-reinforced composites, where failure due to inter-fiber stresses is critical. Overall, these criteria facilitate the assessment of material strength in engineering applications by offering diverse models for various material classes, stress conditions, and practical engineering scenarios.

The rapid development of artificial intelligence, particularly deep learning models, has significantly expanded the spheres of its usage. One of these areas is medicine. One of the important areas of using artificial intelligence in the medical field is the processing of electrocardiograms (ECG). The ECG remains an important tool for the accurate diagnosis of cardiac pathologies in clinical practice. However, accurate processing and analysis of ECG signals, especially the identification of R-waves, remains a challenge. Inaccurate detection of R-peaks can significantly affect further analysis and diagnosis of the disease. Therefore, this study presents an improved method for detecting R-peaks in ECG signals.
The authors propose a method that includes the integration of knowledge into the ECG signal, processing of this information using a convolutional neural network, and post-processing of the CNN model results to detect R-waves. A feature of the proposed method is the integration of knowledge about the reference cardiac cycle into the input ECG signal. The idea of using such integration of knowledge in the ECG signal is that the neural network will better detect R peaks in the ECG signal with integrated knowledge and will be more resistant to changes in signal artifacts.
The accuracy of the proposed method was verified by using ECG signals from 4 databases, namely: MIT-BIH, QT, CPSC-2020, and UoG. The method was evaluated using an error of ±25 ms using statistical metrics accuracy, precision, recall, and F1-score. The obtained statistical indicators are compared with those of existing methods. The proposed method showed the best result on 3 out of 4 test data sets compared to its analogues. Thus, the proposed method is a reliable and efficient solution for detecting R-peaks in ECG signals.

Casting is one of the most common methods of producing workpieces in the machine building and other industries. In particular, sand mold casting is the most common method for ferrous and non-ferrous metals. This casting method requires subsequent knocking out of the castings from the molds and pans, which is a complex technological operation that requires the use of various types of appropriate vibrating equipment, including inertial knockout grids. Automation and continuous development of production sets tasks for the modernization of vibrating equipment and the development of new design solutions, taking into account the possibility of ensuring the required operating modes, specific operating conditions, requirements for durability, reliability, maintainability and safety of use. An important structural element of vibration equipment is vibration exciters, which determine the efficiency of the process of extracting castings from the molds. The paper analyzes the known technical solutions of vibration exciters dedicated to solving this problem and identifies the main directions for improving the design of vibration exciters, as well as problems that require finding effective solutions. Typical designs are considered and the most common types of vibration equipment for knocking out castings are analyzed. The main types of vibration exciter drives used in inertial knockout screens depending on the specifics of production are identified. These are eccentric, cam, unbalanced, pneumatic and electromagnetic. The article analyzes the designs of vibration exciters and their drives and identifies the main advantages and disadvantages. It is concluded that it is necessary and expedient to reduce the weight and simplify the designs, expand the range of operating modes of these drives. It is proposed to use a hydraulic drive of the vibration exciter, which will improve the characteristics of inertial knockout gratings, provide the ability to work with pre- and post-resonance frequencies, expand the range of operating amplitudes and increase the range of processed molds. The expediency and prospects of developing new technological equipment, in particular, hydraulically driven vibration exciters, are indicated.

The results of an experimental study of the effectiveness of cavitation treatment of a fuel mixture based on A-95 gasoline and distilled water for internal combustion engines of electric generators are described. Cavitation treatment of this fuel mixture with a percentage ratio of water / gasoline of 17/83% allows to increase the saving of expensive gasoline by 15-20% when operating gasoline engines of household and industrial generators. At the same time, the engine power is reduced by only 6÷7% due to the cavitation treatment of the water-gasoline fuel mixture.
 A description of the design scheme of the electromagnetic vibrating mixer-cavitator created for the cavitation treatment of water-gasoline fuel is given. Its use will allow not only to save fuel during the operation of electric generators, but also to increase the degree of completeness of combustion of their water-gasoline fuel mixture, that is, it will contribute to the improvement of environmental ecology.
The proposed improved technological scheme for powering the cylinders of the internal combustion engine of the electric generator with cavitationally treated water-gasoline fuel includes supplementing the traditional gasoline supply network with an additional water supply network with a water storage tank and an electromagnetic vibrating cavitator for mixing the water-gasoline mixture.
Experimental studies have established the optimal operating modes of the vibrating cavitation mixer of the fuel mixture. The highest quality of mixing water with gasoline is ensured when the amplitude of oscillations of the cavitation disturbers is in the range of 0.4-0.5 mm at the frequencies of their oscillations of 45-47 Hz.
To form a water-fuel mixture, the technological scheme of the fuel supply of the electric generator is additionally equipped with a water supply system. The water supply system includes a water storage tank, a filter for its purification, a supply pipeline and a vibrating cavitation mixer of water with gasoline. Such additional equipment of the electric generator with a water supply system increases its cost by only 4-5%. With daily operation of electric generators of the Konner and Sohner KS15-1E ATSR model with a capacity of 12.5 kW for 5-6 hours, the costs of its arrangement will pay off in approximately half a calendar year.

The article reviews the current state of scientific research in the field of neural network diagnosis of posttraumatic stress disorder ostents in textual content. Given the low level of diagnosis of posttraumatic stress disorder ostents by means of natural language processing, the way to neural network diagnosis of posttraumatic stress disorder ostents in textual content was proposed with increased resistance to confusion of posttraumatic stress disorder with other mental disorders by creating a training data set containing texts with a high manifestation of posttraumatic stress disorder in the target category, and in the orthogonal category, in addition to ordinary texts without ostents of posttraumatic stress disorder, texts with other mental illnesses.
For neural network diagnosis of posttraumatic stress disorder ostents in textual content, a data set was formed by combining and criterion-based filtering of data based on existing data sets, which includes 3374 records. The neural network for diagnosing posttraumatic stress disorder ostents was trained for 100 epochs with early stops to protect against overtraining, and the best model was saved throughout the training history. The training batch size was 64, the dictionary size was 2000 tokens.
To study the effectiveness of the proposed way to neural network diagnosis of posttraumatic stress disorder ostents in textual content using an error-oriented training dataset, the Google Colab cloud service, which supports various libraries for quantum computing, and the Cirq library were used. The created useless application confirmed the effectiveness of the developed approach to neural network diagnosis of posttraumatic stress disorder ostents in textual content using an error-oriented training dataset. According to the conducted efficiency study, it was possible to achieve the following values for the metrics: Accuracy 0.85, Precision 0.87, AUC 0.88, which is better than existing analogues. The developed wayhas limitations, namely, it works only with English-language texts, however, if training data in other languages ​​​​are available, this limitation can be removed.

Portal grab cranes are an integral part of port infrastructure used to handle bulk materials, including grain, ore, coal, and other dry bulk cargo. However, due to the difficult economic situation, more than 90% of port cranes have reached the end of their standard service life. The supply of new machines to ports remains limited. Since portal cranes play a key role in technological processes, their reliability and uninterrupted operation are critical to the efficiency of port terminals.
Numerous studies have confirmed that fatigue failure, which occurs due to excessive cyclic loads, is the main cause of crane accidents . The intense load cycles inherent in crane operations accelerate the manifestation of this fatigue process. However, the dynamic loads on gantry cranes that have been in operation for more than 40 years remain insufficiently studied. Each individual crane requires a special analysis, since the dynamic characteristics of the mechanisms depend on the conditions of their operation, as well as on the geometric, physical, and mechanical properties of its components.
Given that the forces in the ropes of lifting systems depend on many factors that are difficult or even impossible to take into account during modeling, they are most often determined using experimental methods.
 The paper presents experimental studies of dynamic forces in the lifting mechanism of grab portal cranes “Ganz” with extended service life during sand handling. The object of research is used for handling bulk materials in a seaport. The electrotensometric method was used to determine the dynamic forces. In the course of the research, the lifting speed was simultaneously measured using tachometers that were mounted coaxially with the motor shafts.Based on the experimental data obtained, the probabilistic characteristics of the distribution of operational values of dynamic loads in the lifting mechanism were determined.  The analysis of the data obtained showed that when overloading loads weighing from 8 to 16 tons, the values of the dynamism coefficients in the closing ropes vary from 1.2 to 2. The calculated dynamism coefficients exceed those recommended for gantry cranes, which indicates an overload of the lifting mechanisms. The histogram of the probability distribution of the weight of the load lifted by the crane per work cycle showed that during operation, the crane mainly overloads from 13 to 15 tons of the load being lifted, taking into account the weight of the grab.

Using Moldex3D software allows you to determine the effective structural parameters of the mold and the technological modes of its filling, reducing the likelihood of defects and increasing the efficiency of the production process. Modeling the injection molding process in Moldex3D allows for a detailed analysis of various stages of the technological process: filling, cooling, holding under pressure and ejecting the product from the mold, which significantly reduces the time and resources spent on experimental mode settings.
During the research of the injection molding process of polymer materials in the Moldex3D system, it was found that the holding and cooling stages play a key role in ensuring the quality of the finished part. The use of molds with a cooling system will reduce the duration of the sole holding process, which will contribute to increasing production productivity as a whole. At the same time, with a significant decrease in the temperature of the mold walls, premature solidification of the material is observed, which leads to shrinkage.
The study of the process of feeding the sole during its holding under pressure showed that at an injection pressure of 155 MPa, the time for feeding additional material into the mold cavity is reduced by 1.5 times, which allows increasing production productivity. However, excessively high injection pressure and temperature of the mold walls can contribute to the formation of flaking, i.e. excess polymer material in the form of a thin lip or protrusion on the edge of the component. It is usually thin and can be easily trimmed, so flaking can be considered a minor defect, but an additional operation to remove it leads to an increase in the cost of the production process. It has been established that the joint lines are zones of reduced performance properties of products due to lower adhesion between the flows, and the placement of joints in the finished product is influenced by the relative location of the mold inlet holes. Therefore, when designing molds, one should choose such a location of the inlet holes that ensures either the location of the joint line in areas that are not subjected to significant loads during the operation of the product, or a change in the orientation of the joints relative to the direction of the applied load. Reducing the angle between the joint line and the direction of the load allows to increase the strength and wear resistance of the products during their operation.

The article is devoted to the issues of improving the characteristics of radio communication channels and telemetry of unmanned aerial vehicles. It has been determined that the communication range depends not only on the modem, but also on the antennas, antenna cables, radio wave propagation conditions, external interference, and other reasons.
The communication range is determined by such antenna parameters as the transmitter antenna gain and the receiver gain. The article defines the basic principles for improving the characteristics of radio communication channels and telemetry of unmanned aerial vehicles under various meteorological operating conditions, the effects of electromagnetic interference and terrain relief. It has been determined that to obtain the maximum possible communication range, it is necessary to use cables with the minimum possible attenuation and minimize the length of these cables. In the UAV body, the modem should be located as close as possible to the antenna. The degree of influence of the Earth's surface on the connection also depends on the height of the antennas. The higher the height of the antennas, the greater the distance that can be separated from the points without allowing objects or the underlying surface to fall into the significant zone. It is proposed to take into account the location of antennas, both on the ground and on board the UAV, so that during UAV maneuvers, at least for one of the UAV antennas on the NS - UAV antenna line there are no elements of the UAV design. Thus, it is determined that the loss of communication with the UAV of a certain range can be caused by a local decrease in field strength due to oscillations, thus, if you fly some more distance, the connection can be restored. The final loss of communication will occur only after a significant area is completely covered by objects on the ground or surface relief.

Currently, the use of deterministic chaos signals in information transmission systems represents a promising area of scientific and applied research due to their properties, including wide bandwidth, noise-like behavior, high information capacity, resistance to strong interference, and the ability to synchronize signal generators on both the transmitting and receiving sides.This paper presents a simulation model of a binary information transmission system in the Matlab/Simulink environment, based on the Rucklidge nonlinear dynamic system operating in chaotic mode.
During the transmission of binary messages, unidirectional chaotic synchronization of structurally identical Rucklidge systems occurs on the receiving side. Modulation of the chaotic channel oscillations is achieved by altering the bifurcation parameters of the nonlinear transmitter system. The identification of received logical levels and the information message is accomplished by determining the level of chaotic synchronization between the two nonlinear dynamic Rucklidge systems on the receiving side. The applied criterion for the similarity of the evolution of chaotic systems on both the receiving and transmitting sides determines the accuracy of logical level identification.
The selection of the synchronization criterion directly impacts the system’s tactical characteristics, including immunity to interference, sensitivity to nonlinear distortions, bandwidth, and more.The evolution of chaotic generators is proposed to be compared by utilizing the energy difference of signals from driven nonlinear dynamic systems. Several implementations of the energy criterion were considered, and their impact on the parameters of information signal transmission under conditions of additive interference and nonlinear channel distortions was modeled. As a result of this research, a universal criterion for the level of chaotic synchronization is proposed, involving the normalized energy difference of the signals from the main and auxiliary driven chaotic generators across all phase variables.
Research on the system model for various levels of interference and distortions has shown that the proposed criterion is weakly sensitive to additive noise up to -10 dB and nonlinear channel signal distortions, such as bilateral clipping and step changes in the transmission line up to 20%. This finding allows for the application of this method in logical level identification amid strong interference and moderate nonlinear distortions.

Published: January 2025

This study examines the intersection of Sharia law, apprenticeship schemes, and child rights in Northern Nigeria, a region predominantly Muslim. Apprenticeship schemes are a vital means of economic empowerment and skill acquisition in areas marked by poverty. However, while these programs foster wealth creation, they also raise significant legal concerns regarding child labor, exploitation, and neglect. This research explores how Islamic education supports apprenticeship systems, while also addressing the legal and socio-cultural challenges related to child protection. Given the widespread reliance on apprenticeships in the region, the study is urgently needed to identify how current practices may undermine children's rights and to propose reforms. Drawing on existing literature and fieldwork, the study analyzes the tension between traditional practices and the growing demand for stronger protections for vulnerable children in Northern Nigeria.

The Manifestation Of Religious Moderation As A Middle Way To Face Left And Right Extremism Within The Scope Of State Islamic Religious University
Authors: Ainiyah Nur
Published: January 2025

Abstract: This paper aims to discuss the manifestation of religious moderation as a middle way to deal with left-wing (liberalism) and right-wing (radicalism) extremism within the scope of the State Islamic Religious University (PTKIN). This study emphasizes a qualitative approach with analytical-descriptive studies. The results and discussion of this study show that the concept of religious moderation requires religious people to be more inclusive (open) and not exclusive (closed). Religious moderation is not only an effort to mediate groups that are radical or extreme right, but also our efforts to mediate those who are liberal or extreme left. PTKIN as a forum for Islamic education under the auspices of the Ministry of Religion has an important role in giving birth to a moderate and tolerant young generation with a complex understanding of multiculturalism. Therefore, the manifestation of moderation in religion within the scope of PTKIN in the form of Religious Moderation Houses, religious courses, and the real role (realization) of religious moderation for each individual can lead us to the middle path to face left-right extremism within the scope of PTKIN as well as strengthen the concept of religious moderation that has been built. These aspects can channel us to harmony and harmony in the midst of diversity and diversity within the scope of PTKIN, even wider than that. The existence of this research is expected to be able to make academics and research to develop more widely related to the manifestation of religious moderation in all its forms and efforts, so as to give rise to new innovations to strengthen religious moderation in Indonesia.
Prototype Design and Amenities Clinic Development for Transgender Community
Authors: Zakir Fahad , Imtiaz Ahsan
Published: January 2025

The current study aimed to survey the health challenges and concerns faced by transgender community and gender-diverse individuals in Pakistan. The term ‘transgender’ refers to a marginalized group of people often denied adequate healthcare facilities due to social stigma and discrimination. Some of these health concerns may occur due to an exposure to gender minority stress. Gender minority stress is related to transgenders seeking precautionary healthcare less often than other people do. By employing a participatory design approach including focus groups and co-design workshops with transgenders and gender-diverse (TGD) community members, this study attempted to identify their specific health needs. In response to these challenges, the project proposed a comprehensive healthcare solution that includes both a specialized healthcare facility and a mobile app. This app would allow transgenders to access health forums, consult with doctors, receive tailored wellness advice, and schedule appointments, making healthcare more accessible and user-friendly for this vulnerable population. This combination of physical and digital healthcare support is designed to improve the overall health and well-being of transgenders in Pakistan.

This study aims to reduce the content of formaldehyde in pigment printed cotton fabric with deep shades. A hand screen printing method was applied using various curing temperatures and concentrations of urea for preparation of skin-friendly products. The woven, bleached fabrics were printed following a precise process of screen printing and these samples were dried and curried for proper fixation. Standard test procedures were followed to assess the content of H-CHO (formaldehyde) during washing and rubbing. H-CHO contents were instantly reduced by increasing the temperature of the printed fabric during curing. The best outcome for wet and dry fastness of rubbing was achieved at 160˚C, while a little enhanced rubbing outcomes were observed when the concentration of urea was 2% at a fixation temperature of 150˚C. The final product may be effectively used for clothing purpose, meeting the OEKO-TEX® Standard 100 standard for low formaldehyde content.
Magical Realism and Mythmaking in Pakistani English Children Fiction: A Linguistic Critique of A Firefly in the Dark
Authors: Anosh.  , Asghar Ijaz
Published: January 2025

The current study analyzes the linguistic choices and the language qualities through the co-textual study of the magical and mythical stories inscribed in literary texts in Pakistani fiction, A Firefly in the Dark by Haider (2018). The novel retrieves Pakistani history or magical and cultural embedment wherein these emerged. The aim is to examine whether the selected text involves language that deals with stories based upon magical realities, dreaming qualities, stories of ghosts and gods, daydreaming, horror and myth, imagery and identity, and an amalgamation of rational and irrational worldviews. The textual study would more deeply grasp the historical context and aspects of magical realism and mythmaking linguistic choices inherent in the respective writings. The research is carried out by developing an analytical framework from the existing theories of magical realism by Faris (2004) and Campbell’s theory of hero, mythmaking, and monomyth(Campbell, 1988). By connecting traditional mythmaking with cutting-edge storytelling techniques, Shazaf Fatima Haider's A Firefly in the Dark encompasses the fundamental values of magical realism. By applying the analytical framework to this work, the research examined the text's bridging of the mythmaking traditions and gained a fresh perspective on cultural narratives. It may also open the door to a vast investigation of the language employed in magical and myth-forming literature from South Asia.

Developing Village Index (IDM) is an indicator tool developed based on the concept of the village development framework. This study examines the interaction between the use of Dana Desa (DD) for building village roads, bridges, and drainage systems. In Tirtomoyo District, IDM categorizes villages into two statuses: Developing Villages and Advanced Villages. The study analyzes how these statuses relate to village infrastructure development. The type of infrastructure factor (Factor 1) and the village status factor (IDM) (Factor 2) both have sig values. = 0.000 < ???? = 0.050 so it has an influential relationship with assessments at the planning, implementation and supervision stages of village development. The interaction between Factor 1 and Factor 2 has a sig value. = 0.000 < ???? = 0.050 so that these two factors influence each other on the assessment at the planning, implementation, and supervision stages of village development. The results of the assessment at the planning (RAB) and monitoring stages, developed villages have a higher assessment on 2 infrastructure (roads and bridges) and a smaller value on drainage infrastructure but the difference is not much compared to developing villages, but at the village implementation stage developed villages have a higher assessment of 3 infrastructure (drainage, roads, and bridges) compared to developing villages.
Metaphorical collocations through the prism of language teaching: Why and how they should be included in ESP vocabulary instruction?
Authors: Jelčić Čolakovac Jasmina
Published: January 2025

Figurative language is part of our everyday interactions to a much larger degree than we are probably aware. Metaphorical collocations (MCs) are a specific subset of figurative expressions and as such are currently deemed a necessary part of any language teaching curricula. In MCs, the base, which is usually a noun, retains its literal meaning whereas the collocator (e.g., an adjective or a verb) is used figuratively (Stojić & Košuta 2021). In this paper, the presence of English (L2) metaphorical collocations in a specific set of maritime newspaper articles is explored from the perspective of L2 corpus frequency and the existence of L1 equivalent expressions. Finally, teaching methods are proposed on how to include MCs in ESP vocabulary instruction in a learner-friendly manner that should yield better retention than the traditional approach to vocabulary instruction.
Illocutionary force indicating devices in spoken maritime communications
Authors: Kegalj Jana
Published: January 2025

The paper provides a corpus-driven analysis of different illocutionary force indicating devices (IFIDs) in a spoken corpus of maritime VHF communications. The study relies on the speech act theory (Austin, 1962) and the notion of IFIDs (Searle, 1969). IFIDs refer to various linguistic and non-linguistic devices that indicate the illocutionary force of an utterance, which might include lexical means (verbs, adverbs, etc.), word order, intonation and other means. The study is conducted on a spoken corpus which consists of about ten hours of communication between the ship and the shore. The analysis is performed by employing a combination of quantitative and qualitative approach. First, fifty exchanges are analyzed to identify possible IFIDs. This is followed by corpus analysis of the IFIDs identified in the previous stage. The aim is to shed light on the pragmatic aspect of maritime communications which are otherwise highly structured and institutionalized.

Published: January 2025

In an era of rapid technological advancements and the need for continuous learning, creating and maintaining effective learning ecosystems is essential for fostering adaptive, lifelong learning. This paper explores the theoretical foundations and practical strategies for building learning ecosystems that are sustainable, inclusive, and responsive to diverse learner needs. A learning ecosystem integrates various elements – such as digital tools, physical spaces, pedagogical approaches, and community involvement – to support formal, non-formal, and informal learning. Drawing on interdisciplinary research from education, technology, and systems theory, this paper presents a framework for designing learning ecosystems that promote learner autonomy, collaboration, and adaptability. It also examines key challenges, such as scalability and evolving learner expectations, and proposes strategies for maintaining these ecosystems over time.
