Nonlinear Internal Control System in Business

The purpose of the written study is to study the relationship between the qualifications of the CFO and the nonlinear system of the firm’s internal control system. We used three indicators of the competence of the CFO: financial education, accounting, seniority, and education. Using the model of Kazakhstan companies registered on the stock exchange in 2023. In the methodology of the internal control system, in which stimuli cause a reverse response, the internal control system should be recognized as a nonlinear approach that can have a high impact if it has little impact. The results of this study show a negative relationship between the financial, accounting experience of a CFO and work experience under a nonlinear system of internal control, which indicates that firms with high-quality CFO are facing a nonlinear internal control system in business. A business management team with a large number of employees is associated with an effective internal control system. In addition, the political preferences of senior management directly and indirectly affect the quality of financial statements through the internal control system. Several reliability tests confirm our main results. The results show that a capable CFO can effectively implement a suitable subsystem. The results of the study of a nonlinear system of internal control in business, in terms of improving individual elements of internal control in companies, can be used by members of audit firms.

MaRGE: A graphical environment for MaRCoS

The open-source console MaRCoS, which stands for “Magnetic Resonance Control System”, combines hardware, firmware and software elements for integral control of Magnetic Resonance Imaging (MRI) scanners. Previous developments have focused on making the system robust and reliable, rather than on users, who have been somewhat overlooked. This work describes a Graphical User Interface (GUI) designed for intuitive control of MaRCoS, as well as compatibility with clinical environments. The GUI is based on an arrangement of tabs and a renewed Application Program Interface (API). Compared to the previous versions, the MaRGE package (“MaRCoS Graphical Environment”) includes new functionalities such as the possibility to export images to standard DICOM formats, create and manage clinical protocols, or display and process image reconstructions, among other features conceived to simplify the operation of MRI scanners. All prototypes in our facilities are commanded by MaRCoS and operated with the new GUI. Here we report on its performance on an experimental 0.2 T scanner designed for hard-tissue, as well as a 72 mT portable scanner presently installed in the radiology department of a large hospital. The possibility to customize, adapt and streamline processes has substantially improved our workflows and overall experience.

Организация и порядок подготовки партийно-советских кадров в высших партийных школах КПСС в 1965–1975 гг. (на материалах Ленинградской высшей партийной школы)

This article expands the existing knowledge about the activities of party schools in the Soviet Union and the conditions for organizing the training of party and Soviet personnel. The study is based on the axiological ap-proach, which focuses on analyzing the reasons for the functioning of political regimes, and analyzing archival documents of the Leningrad Higher Party School (LSES), which have not been previously studied in the do-mestic literature. The Higher Party School as an educational organization providing training for Party-Soviet cadres was an intermediary institution in the maintenance of the political regime in the USSR. The implementa-tion of this intermediation took place through three aspects: the formation of the organizational foundations of the activity of the LSES; the reproduction of historical memory, which included “scientific mimicry”; and ele-ments of control in the organization of LSES activity. The study shows that the leadership and teaching staff of the LVPS played in the period 1965–1975 an important role in forming the frame for the professional training of party and Soviet personnel, often acting autonomously from the directives of the CPSU.

Improvement of an ecologically safe system of control of fungal diseases for growing on the basis of organic farming

Goal. To assess the level of effectiveness of the elements of control of fungal diseases in potato agrocenoses for various combinations of biofungicides with biologically active substances and fertilizers, methods of application and the reaction of potatoes of the Myroslav variety to them, for growing on the basis of organic farming.
 Methods. The following methods were used during the research: field — monitoring of the main diseases of potatoes in field experiments, crop accounting, determination of the effectiveness of combinations of biofungicides with plant growth regulators, organic and organo-mineral fertilizers; laboratory — accounting for damage to tubers by diseases, according to generally accepted methods.
 Results. In 2021—2022, the Laboratory of Immunity and Plant Protection of the Institute of Potato Breeding of the National Academy of Sciences conducted research on improving the elements of an environmentally safe system of controlling fungal diseases for cultivation based on organic farming. The research used the Myroslav variety of the institute’s selection, biopreparations with insecticidal, fungicidal and growth-regulating action, and organic and organo-mineral fertilizers. The lowest level of Alternaria development was noted in option 9 (treatment of tubers — organic fertilizer + PPR + plant treatment Bactophyt + PPR + organic and organo-mineral fertilizer), the development of the disease was 25.0%, the spread was 35.0 %, and the technical efficiency of the elements protection was 56.7%. It was established that for effective control of the development of common scab, rhizoctoniosis and fusarium dry rot, it is advisable to use a mixture of substances (PPR + organic fertilizer — treatment of tubers + biofungicide + organic and organo-mineral fertilizer + PPR — plant treatment), which significantly reduced the level of disease development tubers and limited their spread, compared to control and standards. The yield of potatoes in the variants was higher than in the control (22.5 t/ha) and was in the range of 31.1—42.0 t/ha. The level of the preserved harvest, relative to the control, was in the range of 8.6—19.5 t/ ha. The highest level of yield is 42.0 t/ha, noted in option 9 (organic fertilizer + PPR treatment of tubers + three Bactophyt plant treatments + organic and organo-mineral fertilizer + PPR) which, respectively, is 19.5 t/ha higher than the control and by 3.1 t/ha — standard.
 Conclusions. The use of tank mixtures of biofungicides with growth regulators and fertilizers significantly reduces the level of potato disease development and helps to increase the level of its yield. It has been established that the mixture of drugs (PPR + organic fertilizer — treatment of tubers + biofungicide + organic and organo-mineral fertilizer + PPR — plant treatment) is advisable to use to control the development of alternariosis, common scab, rhizoctoniosis and fusarium dry rot, since such a combination is ecologically safe for the environment, at the same time significantly reduces the level of development of fungal diseases and limits their spread, in comparison with control and standards, for growing on the basis of organic farming.

Effects of Seasonal Variation in Plumpness, Biochemical Composition from Scallop (Mizuhopecten yessoensis) on Vitality Changes During Dry Storage

ABSTRACT Vitality is a crucial element in the quality control of live scallops. Nevertheless, the effect of energy fluctuations resulting from the reproductive development of scallops on vitality during storage remains unclear. Changes in the biochemical composition of scallops throughout the year were analyzed, and live scallops with high and low glycogen were selected for dry storage. The results showed that glycogen content fluctuations ranged almost 20-fold between the highest and lowest levels. However, the other proximate composition did not change significantly. Notably, scallops with high glycogen exhibited high levels of ATP and maintained more stable vitality during dry storage.

Relational network of innovation ecosystems generated by digital innovation hubs: a conceptual framework for the interaction processes of DIHs from the perspective of collaboration within and between their relationship levels

AbstractCollaboration plays a key role in the success attained to date by networks of innovation ecosystems generated around entities known as Digital Innovation Hubs (DIHs), recently created following European Commission initiatives to boost the digitisation of the European economic fabric. This article proposes a conceptual framework that brings together, defines, structures and relates the concepts involved in the collaborative interaction processes within and between these innovation ecosystems to allow comprehensive conceptualisation. The developed framework also provides an approach that helps to tangibilise collaboration as a management process. Here the goal is to ultimately move towards not only qualitative, but also quantitative modelling to bridge the research gap in the state of the art in this respect. The data-driven business-ecosystem-skills-technology (D-BEST) model, devised to configure DIHs service portfolios in a collaborative context, provides the reference basis for the interorganisational asset transfer methodology (IOATM). This is the keystone that structures the framework and constitutes its main contribution. Through the IOATM, this conceptual framework points out collaboration quantification, and serves as a lever for its modelling to deal with collaboration accounting by: turning it into a more controllable management element; guiding practitioners' efforts to improve collaborative processes efficiency with an approach that pursues objectivity and maximises synergies.

Effectiveness of a hand hygiene training intervention in improving knowledge and compliance rate among healthcare workers in a respiratory disease hospital

BackgroundPracticing hand hygiene (HH) is a crucial element of infection control, with healthcare workers (HCWs) playing a vital role in preventing the spread of infection. However, inadequate knowledge and non-compliance to HH protocols pose significant challenges in healthcare settings. This study aimed to evaluate the effectiveness of an HH training intervention in enhancing knowledge and staff compliance within a respiratory disease hospital. MethodA pre-and post-training study was conducted among the healthcare workers in a respiratory disease treatment facility. The intervention comprised a series of 3-hour training sessions conducted over five days, focusing on the World Health Organization's (WHO) recommended guideline "Your Five Moments For Hand Hygiene." These sessions covered proper HH techniques and underscored the repercussions of inadequate compliance. Educational materials related to HH were displayed in prominent locations throughout the facility. The knowledge levels and compliance rate were assessed before and after the intervention. ResultThe intervention significantly improved HH knowledge levels and compliance rates among the participants. Marking a significant improvement, the compliance rate of HH protocols increased from 66.0% to 88.3% during the pre-to post-training period, with a concurrent increase in the mean knowledge score from 68.6% to 78.9%. ConclusionThis study underscores the potential of training and education in elevating HH compliance and knowledge among healthcare workers. The findings advocate that healthcare facilities routinely incorporate such interventions into their infection control programs, ultimately improving patient and healthcare worker safety.

Research step of PID control method of stepper motor based on improved fuzzy control algorithm

The significance of PID control within the management system of stepper motors is noteworthy; nonetheless, it is worth noting that stepper motors are susceptible to issues such as low power, step loss, and vibration. The conventional Proportional-Integral-Derivative (PID) control method is insufficient in addressing the control challenge specific to stepper motor management systems. Hence, this research work presents an enhanced fuzzy control method that integrates the principles of fuzzy control theory with traditional PID control theory. The integration of fuzzy control into the P ID control is undertaken to create a fuzzy controller that satisfies the demands of stepper motor control. Additionally, the division of indices is conducted in accordance with the specifications of the fuzzy controller in order to mitigate the disruptive elements of PID control. then, the use of fuzzy control rules is employed to achieve control over the stepper motor, resulting in the development of an enhanced scheme that is then subjected to rigorous validation. The present study employs a MATLAB simulation to compare the performance of the enhanced fuzzy control algorithm with that of the P-ID control method. The results demonstrate that the improved fuzzy control algorithm significantly enhances the stability and dynamic performance of the stepper motor. Superior to traditional Proportional-Integral-Derivative (PID) control.

A hybrid transistor with transcriptionally controlled computation and plasticity

Organic electrochemical transistors (OECTs) are ideal devices for translating biological signals into electrical readouts and have applications in bioelectronics, biosensing, and neuromorphic computing. Despite their potential, developing programmable and modular methods for living systems to interface with OECTs has proven challenging. Here we describe hybrid OECTs containing the model electroactive bacterium Shewanella oneidensis that enable the transduction of biological computations to electrical responses. Specifically, we fabricated planar p-type OECTs and demonstrated that channel de-doping is driven by extracellular electron transfer (EET) from S. oneidensis. Leveraging this mechanistic understanding and our ability to control EET flux via transcriptional regulation, we used plasmid-based Boolean logic gates to translate biological computation into current changes within the OECT. Finally, we demonstrated EET-driven changes to OECT synaptic plasticity. This work enables fundamental EET studies and OECT-based biosensing and biocomputing systems with genetically controllable and modular design elements.

Material flow control in make-to-stock production systems: an assessment of order generation, order release and production authorization by simulation

AbstractMaterial flow control (MFC) is a key element of production planning and control. The literature typically categorizes different MFC methods according to how MFC is realized. This distinction overlooks that MFC decisions can be subdivided into three independent tasks that are executed as orders progress through the system: (i) order generation, (ii) order release, and (iii) production authorization. MFC methods are typically designed for only one of these three tasks, which leaves a large part of the order flow uncontrolled. This study therefore not only provides a new categorization of MFC methods, but also argues for the simultaneous application (or the combining) of three different MFC methods for order generation, order release, and production authorization. To support this argument, the performance effects of an integrated MFC approach are evaluated. Findings show that each individual MFC method impacts different performance metrics, which can be explained by the presence of a hierarchy of workloads, where each workload level constrains the succeeding hierarchical level. Each MFC method has a main impact on a different workload. This has important implications for the design of MFC methods and extends recent literature on hierarchical production planning and control systems.

Linguo-Pedagogical Design of Open Question Items in the Context of Digitalization

Interdisciplinary approach to the development and creation of open question items for assessment procedures in accordance with the digital transformation strategy and the new requirements for state accreditation of educational programs of higher education has been presented in the article. It has been revealed the content of the author’s terms including linguo-pedagogical mastery, linguo-pedagogical design, linguistic correctness and methodological literacy of test tasks. On the basis of scientometric analysis carried out due to the scientific electronic library elibrary it has been determined the chronological activity and subject correlation of publications of native researchers on testing students. Based on the results of a survey of teachers from 11 regional universities the main difficulties in the preparation of testing and assessment materials are summarized. Examples of test items in disciplines taught at a multidisciplinary polytechnic university are analyzed. Typical errors in the wording of questions, reference answers and evaluation criteria have been identified by the methods of erratological analysis and the reasons for their appearance have been summarized. To model the linguo-pedagogical design of test tasks the concept of an epistemic situation is used, its four components are described: ontological (subject-content definition of objects and elements of control), methodological (selection of types and types of tasks depending on the level of measured outcomes of learning), communicative-pragmatic (ensuring the comprehensibility of the text of the test task) and technological (technical implementation of the automated check of free response). Methods of test tasks modification with the help of modern digital services are proposed. As a result of the study, the authors formulate recommendations for the implementation of the linguo-pedagogical design of open question items with a focus on their implementation in the digital environment.

МЕТОДОЛОГІЧНІ АСПЕКТИ ДОСЛІДЖЕННЯ МЕТАКОГНІТИВНОГО КОНТРОЛЮ СТУДЕНТІВ НАЦІОНАЛЬНОЇ БЕЗПЕКИ В КОНТЕКСТІ САМОРЕГУЛЬОВАНОГО НАВЧАННЯ

This article presents an analysis of the main theoretical and methodological foundations for researching metacognitive control among students specializing in National Security within the context of self-regulated learning. It highlights the growing interest in psychological science regarding the problem of self-regulated learning effectiveness and the researchers' desire to develop functioning tools for assessing learning strategies. Based on classical postulates about methodology as a system of principles and methods for organizing and constructing theoretical and practical activities, the article analyzes theoretical models, characteristics, and components of self-regulated learning and the place of metacognitive control within this system. It considers Pintrich's theoretical model of self-regulated learning, which studies self-regulation of learning, particularly metacognitive control, across four spheres: cognitive, motivational-emotional, behavioral, and contextual. The latter distinguishes this model from others, as it includes the contextual area as a subject of self-regulation. Special attention is given to analyzing key elements of metacognitive control – learning strategies that can significantly enhance the chances of successful and effective learning. It is found that learning strategies relate to the effective selection and organization of information, efficient repetition of material with subsequent assimilation, establishing connections between new information and information already stored in memory, understanding, monitoring, and continuously enhancing the meaningfulness of the material. It is noted that an important aspect of the interconnection between learning strategies and metacognitive abilities is the effective management of resources, not necessarily related to cognitive activity – time management, managing the learning environment, group learning, and seeking feedback. The third level of methodology discusses a set of specific techniques and technical research approaches for investigating metacognitive control in students of higher education institutions specializing in “National Security”: LASSI, Weinstein, Schulte, Palmer, 1987. The conclusion is drawn that self-regulated learning (and thus, the ability to apply metacognitive control) characterizes students as actively engaged in the learning process: they maintain their motivation, are aware of their thinking processes, and know how to use a wide range of strategies to achieve desired academic outcomes. The article identifies the main methodological problems associated with the empirical study of the effectiveness of self-regulated learning: using different tools to study cognitive, metacognitive, and motivational aspects of self-regulated learning, which separately does not consider its regulatory nature; the need to increase students' awareness of the characteristics of self-regulated learning and the use of learning strategies for accurate self-reports and self-assessment of these processes; since SRL is a specific, not a general process, differences in research results can be observed depending on the context or situation.

Infants on the move: bibliometric analyses of observational vs. digital means of screening infant development.

Neurodevelopmental disorders are on the rise, yet their average diagnosis is after 4.5 years old. This delay is partly due to reliance on social-communication criteria, which require longer maturation than scaffolding elements of neuromotor control. Much earlier criteria could include reflexes, monitoring of the quality of spontaneous movements from central pattern generators and maturation of intentional movements and their overall sensation. General Movement Assessment (GMA) studies these features using observational means, but the last two decades have seen a surge in digital tools that enable non-invasive, continuous tracking of infants' spontaneous movements. Despite their importance, these tools are not yet broadly used. In this work, using CiteSpace, VOSViewer and SciMAT software, we investigate the evolution of the literature on GMA and the methods in use today, to estimate how digital techniques are being adopted. To that end, we created maps of key word co-occurrence networks, co-author networks, document co-citation analysis and strategic diagrams of 295 publications based on a search in the Web of Science, Dimensions and SCOPUS databases for: 'general movement assessment' OR 'general movements assessment'. The nodes on the maps were categorized by size, cluster groups and year of publication. We found that the state-of-the-art methodology to diagnose neurodevelopmental disorders still relies heavily on observation. Several groups in classical GMA research have branched out to incorporate new techniques, but few groups have adopted digital means. We report on additional analyses of methods and biosensors usage and propose that combining traditional clinical observation criteria with digital means may allow earlier diagnoses and interventional therapies for infants.

Design, implementation, and experimental validation of a new low-cost sensorless wind turbine emulator: Applications for small-scale turbines

Research and investigation into renewable energy sources is being sparked by the rapidly rising need for electricity, higher costs of fossil fuels, and increasing worries about the environment. Recent years have seen a tremendous increase in the use of wind energy (WE). In-depth study has been done to effectively produce power from WE. Nevertheless, it is exceedingly challenging and dangerous to set up wind turbines (WTs) for research and teaching uses due to constraints like space and upkeep. Numerous benefits come with a lab-scale WT emulator (WTE), such as freedom from space restrictions, an improved level of control, and independence from existing weather conditions. The design and execution of a low-power, lab-scale WTE are the focus of this study. The investigated experimental configuration is intended to precisely mimic the mechanical behavior of a real WT. Aerodynamics, blades, slow shafts, gearboxes, and controller elements, for example, are modeled in MATLAB/Simulink before they are assembled and implemented on a dSPACE 1104 board. A DC motor running under buck converter control is used to substitute the quick shaft. The WTE’s functionality is evaluated in various wind speed conditions. The findings of comparing the WTE’s dynamics with those offered by the manufacturer amply show the efficacy of the proposed WTE and its capacity to take the position of an actual WT. This paper will be a useful resource for investigators in helping them select the best WTE approach for their purposes.

A Novel Scheme to Protect Distribution Networks in Presence of Inverter-Based Distributed Generation

One of the most important challenges of distributed generation (DG) development in distribution systems is their protection. It is necessary to have a scheme for keeping the protection settings unchanged. In this paper, adverse impacts of the inverter based distributed generation (IBDG) are evaluated, and an algorithm is proposed to limit the fault current, feed, which is generated by IBDGs. This algorithm is only implemented on the inverter controller and other elements are not used in fault current limitation. The simulation results are provided to verify the proposed control scheme.

Strategic behaviour and resilience of an industrial enterprise to the external environment

The growing turbulence of the environment requires an industrial enterprise to find new approaches to choosing its development strategy. The study proposes a method for assessing the level of resilience of machine-building companies depending on the type of their strategic behaviour. Methodologically, the research rests on the theory of the firm and strategic management theory. Structural and logical analysis, expert assessments, matrixing, statistical and financial analysis were used as research methods. The empirical evidence is the data from the Russian Federal State Statistics Service (Rosstat) and the SBIS counterparty verification system. We clarify the concepts of resilience and strategic behaviour of a machine-building enterprise and propose our own definition of resilience. We distinguish between four types of strategic behaviour of enterprises when contacting the external environment, namely the maximum control possible, constructive interaction, adaptation with elements of control, and forced adaptation. A relationship was discovered between the level of resilience and the type of strategic behaviour of an industrial enterprise. The findings were tested using the case of four machine-building plants specializing in the production of lifting equipment. We found significant differentiation in the level of resilience of the enterprises under study and established which of the four types of strategic behaviour was typical of each. This will allow them to exercise a more reasonable approach when instituting their development strategy amid turbulence.
