Hybrid Anomaly Detection in Time Series by Combining Kalman Filters and Machine Learning Models
Authors: Puder Andreas , Zink Moritz , Seidel Luca , Sax Eric
Published: May 2024

Due to connectivity and automation trends, the medical device industry is experiencing increased demand for safety and security mechanisms. Anomaly detection has proven to be a valuable approach for ensuring safety and security in other industries, such as automotive or IT. Medical devices must operate across a wide range of values due to variations in patient anthropometric data, making anomaly detection based on a simple threshold for signal deviations impractical. For example, surgical robots directly contacting the patient’s tissue require precise sensor data. However, since the deformation of the patient’s body during interaction or movement is highly dependent on body mass, it is impossible to define a single threshold for implausible sensor data that applies to all patients. This also involves statistical methods, such as Z-score, that consider standard deviation. Even pure machine learning algorithms cannot be expected to provide the required accuracy simply due to the lack of available training data. This paper proposes using hybrid filters by combining dynamic system models based on expert knowledge and data-based models for anomaly detection in an operating room scenario. This approach can improve detection performance and explainability while reducing the computing resources needed on embedded devices, enabling a distributed approach to anomaly detection.
Soft Sensory-Motor System Based on Ionic Solution for Robotic Applications
Authors: Santos Sender Rocha dos , Rohmer Eric
Published: May 2024

Soft robots claim the architecture of actuators, sensors, and computation demands with their soft bodies by obtaining fast responses and adapting to the environment. Sensory-motor coordination is one of the main design principles utilized for soft robots because it allows the capability to sense and actuate mutually in the environment, thereby achieving rapid response performance. This work intends to study the response for a system that presents coupled actuation and sensing functions simultaneously and is integrated in an arbitrary elastic structure with ionic conduction elements, called as soft sensory-motor system based on ionic solution (SSMS-IS). This study provides a comparative analysis of the performance of SSMS-IS prototypes with three diverse designs: toroidal, semi-toroidal, and rectangular geometries, based on a series of performance experiments, such as sensitivity, drift, and durability. The design with the best performance was the rectangular SSMS-IS using silicon rubber RPRO20 for both internal and external pressures applied in the system. Moreover, this work explores the performance of a bioinspired soft robot using rectangular SSMS-IS elements integrated in its body. Further, it investigated the feasibility of the robot to adapt its morphology online for environment variability, responding to external stimuli from the environment with different levels of stiffness and damping.

Published: May 2024

How to reduce fuel consumption to mitigate CO2 emissions to the atmosphere and improve road safety is one of the priorities to be addressed in the field of transport in the European Union. Considering the trend towards more frequent car rentals, it seems important to encourage drivers to change their driving style to a more ecological and economic one. This can be achieved by a system (built of a sensor located in the car, analytical software in the cloud and a mobile application for displaying results) that analyzes driving style and tells the driver how to drive better. Solutions such as the car bus PCB, GSM/GPS modem and 3D sensors were used in the development of the sensor. The validation of the sensor and the development of the analytical system are based on tests carried out in road conditions and in a closed area. Graphical methods (box-plot charts), correlation analysis and testing statistical hypotheses using the Mann–Whitney method were used in the analysis of the test results. The developed sensor and the analytical system allow for identifying the driving style of drivers. This system, through the use of a sensor that allows for downloading data not only from the car’s CAN bus but also the forces acting on the vehicle, permits the checking of 14 driving parameters used to interpret the driver’s driving style.

Authors: Sæþórsdóttir Anna Dóra , Tverijonaite Edita
Published: May 2024

The increase in wilderness use for nature-based tourism has complex implications for wilderness management. Tourism service providers play an important role in shaping tourism development trends, which can have an impact on wilderness. This stresses the importance of studying their perceptions and preferences regarding wilderness management. This study explores the meanings wilderness areas contain for tourism operators, the relationship of these meanings with wilderness management and development preferences, and the potential of place-based approaches to contribute to wilderness management. The study is based on 47 semi-structured interviews with tourism service providers offering services within or near the Icelandic Central Highlands, known for their vast, high-quality wilderness areas. The findings emphasize the importance of place meanings assigned by tourism service providers in shaping wilderness management preferences. The study highlights the usefulness of place-based management approaches, which can help identify potential conflicts between tourism and wilderness preservation, select proactive measures to minimize tourism’s impact on wilderness quality, and thereby facilitate sustainable tourism practices in wilderness.

Authors: Jula Nicolae Marius , Staicu Gabriel Ilie , Moraru Liviu Cătălin , Bodislav Dumitru Alexandru
Published: May 2024

The emergence of e-commerce reshaped the traditional trade models, also playing a significant role in meeting the UN sustainable development goals. According to the UN, sustained growth and social development must include resilient infrastructure, foster innovation, allow for better access to information and communications technology, and universal and affordable internet infrastructure. This study explores a multidimensional analysis of e-commerce development in the EU generated by the following factors: education, internet infrastructure, income, and economic freedom. We use an ARDL econometric model and Eurostat data. Additionally, we analyze the time responsiveness of e-commerce growth to changes in these factors. In the long run, our findings identify a stable and positive relationship between e-commerce and all these factors. However, in the short run, our results illustrate significant dynamics between two variables and e-commerce. Specifically, the level of internet access and the percentage of individuals who use the internet daily exhibit a positive short-run impact on e-commerce sales, with the system absorbing shocks within a short period. This research advocates for targeted policies that support innovation, fair competition, and consumer protection in the digital economy. This research provides valuable guidance for policymakers and stakeholders in improving the institutional framework to promote a sustainable development of e-commerce in the EU.

Authors: Gu Yaoting , Lao Xianlan , Zhuo Lilisha , Li Xiaochang , Deng Chuxiong
Published: May 2024

Clearing and successfully characterizing ecosystem service flow paths has become a key bottleneck restricting in-depth research on the supply and demand relationships of ecosystem services. At present, although some explorations have been performed using water ecosystem services as a pioneer, the nature of its network and the fact that ecological base flow needs to be eliminated have been ignored. This study used InVEST and network models to consider ecological base flow, quantifying the supply, demand, and flow paths of freshwater ecosystem services in the Xiangjiang River Basin. The results showed that the overall distribution of the water supply in the Xiangjiang River Basin from 2000 to 2020 shows a pattern of higher supply in the south and lower supply in the north. The distribution of water demand shows higher levels in the north and lower levels in the south. The network density remains at its maximum level. The results of this study have provided a scientific basis for water resource management in river basins and improving ecological compensation mechanisms.

Authors: Gürsoy Samet , Jóźwik Bartosz , Dogan Mesut , Zeren Feyyaz , Gulcan Nazligul
Published: May 2024

This research aimed to investigate the relationship between climate policy uncertainty (CPU), clean energy (ENERGY), carbon emission allowance prices (CARBON), and Bitcoin returns (BTC) for the period from August 2012 to August 2022. The empirical analysis strategies utilized in this study included the Fourier Bootstrap ARDL long-term coefficient estimator, the Fourier Granger Causality, and the Fourier Toda–Yamamoto Causality methods. Following the confirmation of cointegration among the variables, we observed a positive relationship between BTC and CARBON, a positive relationship between BTC and CPU, and a negative relationship between BTC and ENERGY. In terms of causal associations, we identified one-way causality running from CARBON to BTC, BTC to CPU, and BTC to the ENERGY variable. The study underscores the potential benefits and revenue opportunities for investors seeking diversified investment strategies in light of climate change concerns. Furthermore, it suggests actionable strategies for policymakers, such as implementing carbon taxes and educational campaigns, to foster a transition towards clean energy sources within the cryptocurrency mining sector and thereby mitigate environmental impacts.

Published: May 2024

Accurate and fast traffic prediction is the data-based foundation for achieving traffic control and management, and the accuracy of prediction results will directly affect the effectiveness of traffic control and management. This paper proposes a new spatiotemporal periodic polynomial model for road traffic, which integrates the temporal, spatial, and periodic features of speed time series and can effectively handle the nonlinear mapping relationship from input to output. In terms of the model, we establish a road traffic speed prediction model based on polynomial regression. In terms of spatial feature extraction methods, we introduce a maximum mutual information coefficient spatial feature extraction method. In terms of periodic feature extraction methods, we introduce a periodic trend modeling method into the prediction of speed time series, and effective fusion is carried out. Four strategies are evaluated based on the Guangzhou road speed dataset: a univariate polynomial model, a spatiotemporal polynomial model, a periodic polynomial model, and a spatiotemporal periodic polynomial model. The test results show that the three methods proposed in this article can effectively improve prediction accuracy. Comparing the spatiotemporal periodic polynomial model with multiple machine learning models and deep learning models, the prediction accuracy is improved by 5.94% compared to the best feedforward neural network. The research in this article can effectively deal with the temporal, spatial, periodic, and nonlinear characteristics of speed prediction, and to a certain extent, improve the accuracy of speed prediction.
The Schwarzschild–de Sitter Metric of Nonlocal dS Gravity
Authors: Dimitrijevic Ivan , Dragovich Branko , Rakic Zoran , Stankovic Jelena
Published: May 2024

It is already known that a simple nonlocal de Sitter gravity model, which we denote as dS gravity, contains an exact vacuum cosmological solution that mimics dark energy and dark matter and is in very good agreement with the standard model of cosmology. This success of dS gravity motivated us to investigate how it works at a lower-than-cosmic scale—galactic and the solar system. This paper contains our investigation of the corresponding Schwarzschild–de Sitter metric of the dS gravity model. To obtain an exact solution, it is necessary to solve the corresponding nonlinear differential equation, which is a very complicated and difficult problem. What we obtained is a solution to a linearized equation, which is related to space metrics far from the massive body, where the gravitational field is weak. The obtained approximate solution is of particular interest for examining the possible role of nonlocal de Sitter gravity dS in describing the effects in galactic dynamics that are usually attributed to dark matter. This solution was tested on the Milky Way and the spiral galaxy M33 and is in good agreement with observational measurements.
Supernova Remnants in Gamma Rays
Authors: Giuliani Andrea , Cardillo Martina
Published: May 2024

In the 1960s, the remnants of supernova explosions (SNRs) were indicated as a possible source of galactic cosmic rays through the Diffusive Shock Acceleration (DSA) mechanism. Since then, the observation of gamma-ray emission from relativistic ions in these objects has been one of the main goals of high-energy astrophysics. A few dozen SNRs have been detected at GeV and TeV photon energies in the last two decades. However, these observations have shown a complex phenomenology that is not easy to reduce to the standard paradigm based on DSA acceleration. Although the understanding of these objects has greatly increased, and their nature as efficient electron and proton accelerators has been observed, it remains to be clarified whether these objects are the main contributors to galactic cosmic rays. Here, we review the observations of γ-ray emission from SNRs and the perspectives for the future.

Coal mining activity contributes to energy security and employment occupation, but is associated with environmental deterioration. Coal combustion leads to GHG emissions, while coal mining results in the generation of saline effluents. These effluents are discharged in inland surface waters, applying significant pressure on their quality, with a negative impact on aquatic life and the economy of a region. This study includes water samples that were analyzed in order to investigate the organic compounds, heavy metals, and other physicochemical parameters. Biological monitoring was done according to the Water Framework Directive methodology. The results from an aquatic area in Southern Poland, which indirectly receives coal mine effluents, indicate elevated salinity with excessive chlorides, sulfates, and sodium ions. The water quality of another non-polluted aquatic area was also assessed to examine the impact of indirect coal mine wastewater discharge on this area. The high salinity levels hinder the use of river water for drinking, agricultural, or industrial purposes. The results obtained show high pressure on the ecological status of streams and rivers that receive mine effluents, and on the density and diversity of aquatic invertebrates. This pressure is clearly visible in the structure of benthic communities and in invertebrate diversity. It also contributes to the appearance of invasive species and increasing water salinity. Limiting discharges of mine water transporting large loads of saline substances would reduce the negative impact on the quality of river waters and biological life.
Vascular Access Outcomes in Patients with Autosomal Dominant Polycystic Kidney Disease
Authors: Laboyrie Suzanne L. , Svensson Maria K. , Josemans Sabine , Sigvant Birgitta , Rotmans Joris I. , Welander Gunilla
Published: May 2024

Key Points

More patients with autosomal dominant polycystic kidney disease received their first intervention to re-establish vascular access patency.

Patients with autosomal dominant polycystic kidney disease do not require differential monitoring and treatment of hemodialysis vascular access.

Background

Autosomal dominant polycystic kidney disease (ADPKD) is a leading hereditary cause of ESKD, often using hemodialysis as a form of RRT. Patients with ADPKD may also present with extrarenal manifestations, including arterial aneurysms. The gold standard for hemodialysis access is an arteriovenous vascular access (VA), such as arteriovenous fistulas (AVFs) or arteriovenous grafts (AVGs). However, limitations, such as low VA flow and inadequate AVF outward remodeling, affect VA utilization. This study aimed to explore whether ADPKD affects patency rates of AVFs/AVGs in comparison with other underlying ESKD causes.

Methods

We conducted a retrospective cohort study using data from the Swedish Renal Registry from 2011 to 2020, with follow-up until 2022. We included 496 patients with ADPKD and 4321 propensity score–matched controls. VA patency rates of patients with ADPKD were compared with those of non-ADPKD patients using Kaplan–Meier survival curves and Mantel–Cox log-rank test. Interventions to maintain or restore patency were also analyzed.

Results

Patients with ADPKD constituted 8.0% of all patients, with a higher proportion in the pre-ESKD phase during VA creation (51.6% versus 40.6%). No significant differences were observed in primary, postcannulation primary, secondary, or functional patency between patients with ADPKD and non-ADPKD patients. However, more VAs were ligated in patients with ADPKD (10.5% versus 7.7%, P = 0.03), and they underwent more first interventions to re-establish flow (49.4% versus 41.9%, P = 0.02).

Conclusions

These findings suggest that AVF/AVG patency remains comparable in patients with ESKD with or without ADPKD, and VA monitoring and treatment strategies for patients with ADPKD should align with those for individuals with other ESKD causes.

Published: May 2024

Key Points

Among patients with severe polycystic liver disease (PLD) (height-adjusted total liver volume of <1800 ml/m), PKD2 variants were found in 34%.

Three patients with PKD1 or PKD2 variants are reported with severe PLD but normal-sized kidneys (hTKV of < 250 ml/m).

Background

Polycystic liver disease (PLD) is present in most patients with autosomal dominant polycystic kidney disease (ADPKD). PLD can alternatively be found with few, if any, kidney cysts as a diagnosis of isolated PLD (autosomal dominant PLD [ADPLD]). Several genes are identified as causative for this spectrum of phenotypes; however, the relative incidence of genetic etiologies among patients with severe PLD is unknown.

Methods

Patients with ADPKD or ADPLD having severe PLD defined as height-adjusted total liver volume (hTLV) >1800 ml/m were recruited. Subsequent clinical care was followed. Genetic analysis was performed using whole exome sequencing.

Results

We enrolled and sequenced 49 patients (38 women, 11 men). Pathogenic or suspected pathogenic variants in polycystic disease genes were found in 44 of 49 patients (90%). The disease gene was PKD1 in 20 of 44 patients (45%), PKD2 in 15 of 44 patients (34%), PRKCSH in 5 of 44 patients (11%), GANAB in 2 of 44 patients (5%), SEC63 in 1 of 44 patients (2%), and ALG8 in 1 of 44 patients (2%). The median hTLV was no different between genetically defined ADPKD and ADPLD groups (4431 [range, 1817–9148] versus 3437 [range, 1860–8211]) ml, P = 0.77), whereas height-adjusted kidney volume was larger as expected in ADPKD than in ADPLD (607 [range, 190–2842] versus 179 [range, 138–234] ml/m, P < 0.01). Of the clinically defined ADPKD patients, 20 of 38 patients (53%) were PKD1, 15 of 38 (39%) were PKD2, and 3 (8%) remained genetically unsolved. Among patients with a pathogenic PKD1 or PKD2 variant, we found three patients with a liver-dominant ADPKD (severe PLD with height-adjusted total kidney volume <250 ml/m).

Conclusions

ADPLD-related genes represent 20% of patients with severe PLD in our cohort. Of those enrolled with ADPKD, we observed a higher frequency of PKD2 carriers than in any previously reported ADPKD cohorts. Although there was no significant difference in the hTLV between patients with PKD1 and PKD2 in this cohort, our data suggest that enrollment on the basis of severe PLD may enrich for patients with PKD2.
SQUATTING AS A MODEL OF HOUSING FOR VULNERABLE AND NEGLECTED POPULATION
Authors: Djordjevic Snezana
Published: May 2024

Abstract
The main topic of the paper is squatting as a model of housing. It has appeared and developed in times of great housing availability for vulnerable populations. The topic belongs to the housing policy research field and represents neglected and „forgotten“themes, which in our neoliberal world of rising social inequities, starts again to be important. Research methods are: in view in the literature, case studies (cities like London - UK, Madrid, Barcelona – Spain, and Amsterdam - Netherlands) and comparative method with generalization (learning from these experiences) for tailoring housing policy, sensible to vulnerable population`s needs. The main research findings are that squatting put a different (rather radical) light on the „right to housing“ as a prerequisite for a decent quality of life for each person and society too.

Keywords: housing policy, affordable and social housing, squatting, neoliberal city, squatting movement, just city.

ОЦІНЮВАННЯ ЯКОСТІ ДИЗЕЛЬНОГО ПАЛИВА ЗА ГУСТИНОЮ І В’ЯЗКІСТЮ
Authors: ГУСАЧУК Д. А. , ФЕЩУК Ю. П. , ФУРС Т. В.
Published: May 2024

Робота присвячена дослідженню якості за густиною і в’язкістю зразків дизельного палива (ДП), присутніх на ринку України в умовах воєнного стану. Проаналізовано основні експлуатаційні вимоги до дизельних палив, виконання яких задовольняє надійну й економічну роботу двигунів. Акцентовано увагу на питанні забезпечення якості ДП, що оцінюється низкою фізико-хімічних показників, основними серед яких є густина і в’язкість. Зазначено, що ці параметри залежать від фракційного і вуглеводневого складу палива. Проведено аналіз впливу густини і в’язкості на процеси випаровування пального і сумішоутворення, а також загалом на роботу паливної системи двигуна. У контексті експлуатаційних вимог обгрунтовано важливість контролю відповідності фізико-хімічних показників нафтових автомобільних палив нормам ДСТУ 7688:2015 «Паливо дизельне Євро. Технічні умови». Зокрема, густину ДП визначають для розрахунку дозувальних приладів систем живлення, а також для обліку витрати палива. Проаналізовано негативні наслідки для роботи двигуна, викликані відхиленням величини кінематичної в'язкості і густини палива від стандартного значення. Описано методики, згідно яких виконано вимірювання густини й визначення кінематичної в’язкості досліджуваних зразків. Вимірювання густини проведено безпосередньо за допомогою ареометра, значення приводили до нормованої температури 15 °С. Визначення кінематичної в’язкості здійснено за допомогою спеціального приладу, основними конструктивними елементами якого були капілярний віскозиметр і рідинний термостат, який забезпечував стабільність температури пального +40°С (стандартне значення). Наведено дані експериментів та обчислень густини й кінематичної в’язкості, виконано порівняння одержаних значень з вимогами стандарту ДСТУ 7688:2015 «Паливо дизельне Євро. Технічні умови», а також з нормативними вимогами європейських стандартів. За результатами досліджень густини і кінематичної в’язкості зроблено висновок про якість, експлуатаційні властивості і придатність до використання досліджуваних зразків дизельних палив.
КЛАСИФІКАЦІЯ МЕТОДІВ ДИСКРЕТНОГО ЛОГАРИФМУВАННЯ НА ЕЛІПТИЧНІЙ КРИВІЙ
Authors: ОНАЙ М. В. , ГУЛЬКО Д. Т.
Published: May 2024

У цій роботі проведено аналіз та класифікацію методів розв’язання задачі дискретного логарифмування у мультиплікативних та адитивних групах, а також обґрунтовано актуальність такого аналізу. Особливий акцент зроблено на розв’язанні цієї задачі на еліптичних кривих над скінченними полями. Робота спрямована на підвищення стійкості криптографічних систем шляхом аналізу та класифікації існуючих методів вирішення задачі дискретного логарифмування. У статті розглянуто такі методи: метод перебору, метод Поліга-Геллмана, метод Деніела Шенкса та його модифікації, а саме метод Кенгуру та метод “Two Grumpy Giants and a Baby”. Окрім того, у роботі розглянуто ρ-метод Полларда та його модифікацію, що передбачає розпаралелення на декілька потоків виконання, а також метод Лас-Вегаса – сучасний метод, що використовує матричні обчислення для розв'язання задачі дискретного логарифмування. Ключовим аспектом цієї статті є комплексний порівняльний аналіз методів дискретного логарифмування, результати аналізу наведено у відповідних таблицях, де подана їх часова та просторова складність, а також низка інших показників. Проведений аналіз надає інформацію про ефективність, безпеку та практичність кожного методу, закладає основу для подальших досліджень, а також дозволяє будувати більш стійкі криптосистеми. Визначено, що ρ-метод Полларда має найкращий баланс між швидкодією та пам’яттю, що використовується, тому висунуто гіпотези щодо його покращення. Перша гіпотеза полягає у тому, що при перевірці на існування колізії на кожній ітерації алгоритму, що реалізує цей метод, доцільно порівнювати не точки, а їх класи еквівалентності. Друга гіпотеза покращення полягає у скороченні інтервалу, в якому знаходиться колізія. Іншим перспективним методом вирішення задачі дискретного логарифмування є метод Лас-Вегаса, що має високу швидкодію, проте цей метод не гарантує рішення і має високу просторову складність.

Оскільки багато фізичних та інженерних явищ можна математично описати диференціальними рівняннями, але знаходження їх аналітичних розв'язків часто є складним завданням, чисельні методи для наближеного розв'язання стають критично важливими. Ці методи необхідні для комп'ютерного моделювання та симуляції складних технічних систем. Ураховуючи різноманітність диференціальних рівнянь, наближені методи виступають універсальним інструментом, придатним для вирішення важливих завдань у різних галузях, і дозволяють краще враховувати вимоги сучасних обчислювальних технологій. Використання нейронних мереж для наближеного розв'язання диференціальних рівнянь є перспективним напрямком у галузі наукового моделювання. Інноваційний підхід полягає включенні в мережу фізичної інформації у вигляді складної функції втрат, що поєднує традиційні методи розв'язання фізичних задач із передовими техніками глибокого навчання. У такому підході нейронна мережа, призначена для апроксимації функцій, отримує на вхід не лише вхідні дані, але й фізичну інформацію про систему чи процес, яку вона моделює. Цю фізичну інформацію можна включити у вигляді додаткових параметрів, обмежень чи рівнянь. Складна функція втрат враховує якість апроксимації нейронною мережею, а також фізичні принципи задачі. Це дозволяє нейронним мережам адаптуватися до фізичних обмежень і забезпечує наближене розв'язання задач, враховуючи важливі аспекти фізичної структури. Зазвичай використовуються прості архітектури, наприклад мережі прямого поширення сигналу з невеликою кількістю шарів. У даній роботі досліджується можливість розв’язання нелінійних задач пружності нейромережевим підходом.

Робота присвячена формуванню наукового підґрунтя щодо обґрунтування використання математичного апарату в публічному управлінні фінансово-економічними процесами на національному рівні. В роботі доведено, що більшість процесів на макрорівні економіки мають циклічний характер розвитку. Прогнозування початку та закінчення циклу – актуальна задача сьогодення, оскільки це надає можливість приймати обґрунтовані об’єктивні рішення на всіх рівнях публічного управління. Саме така задача ідентифікації циклів в макроекономічній системі розглядається роботі. В дослідженні була поставлена задача, на основі статистичних даних щодо протікання реальних фінансово-економічних процесів на національному рівні, необхідно побудувати ймовірнісну модель для ідентифікації циклів на основі принципу класифікації даних та встановити ефективність використання різних стратегій класифікації та дослідити якість класифікації шляхом порівняння отриманих результатів з експертними оцінками. В статті запропонована концепція використати мережі Байеса для ідентифікації (розпізнавання) фаз розвитку процесів довільної природи, представлених часовими рядами даних, зокрема в економіці та фінансах. Попередні дослідження, виконані в даному напрямі, свідчать про можливість отримання прийнятних позитивних результатів. Для цього необхідно створити спеціальні ймовірнісні моделі та оцінити їх параметри за допомогою статистичних даних стосовно розвитку процесу. Для аналізу наявності циклів у процесах на макрорівні в роботі запропоновано використати сучасний апарат ймовірнісного моделювання – мережі Байєса. На основі статистичних даних побудована структура мережі, яка застосована для виявлення циклів на заданому часовому інтервалі. Коректність отриманого результату підтверджена експертними оцінками. Для виявлення можливих циклів у фінансово-економічних процесах запропоновано використати динамічні мережі Байєса, які представляють ефективний інструмент аналізу процесів довільної природи. В результаті навчання мережі та її використання виявлення бізнес-циклів встановлено, що похибка класифікації складає не більше 16,5%, що є цілком прийнятним результатом для даного випадку. Окреслено напрями наукового пошуку та подальших досліджень щодо обґрунтування можливостей застосування мереж Байєса для моделювання і прогнозування розвитку процесів публічного управління різних рівнів. Зокрема, встановлення можливості їх застосування до розв’язання задач управління ресурсами та ризиками, пов’язаними з реалізацією управлінських рішень.

Professional morality consists primarily of such activities, the object of which is a person. Undoubtedly, working with people presents unique situations, difficulties, and contradictions that need to be resolved and overcome in the course of the activity itself. The qualitative peculiarity of the nature of relations between people in each profession implies that the activity complies with certain social norms and standards, moral and ethical requirements. Therefore, professional morality, on the one hand, is a component of general morality, and on the other hand, it has a qualitative specificity. The connection between them is expressed in the dialectic of the general and the particular. Ethics plays an important role in all areas of life, including professional activities. In a professional context, ethics defines the rules and norms of behavior that are aimed at ensuring fairness, trust and responsibility in the performance of professional duties.
The basic principles of professional ethics may include: honesty and integrity: professionals must demonstrate honesty and a high level of integrity, refraining from fraud, forgery and dishonesty. Confidentiality: the obligation to maintain the confidentiality of information obtained in the course of work that relates to clients, patients or other parties.
 Integrity and equality: ensuring fairness in dealing with customers, patients, colleagues and other stakeholders and avoiding discrimination. Responsibility: taking responsibility for your actions and accepting the consequences of your actions. Social responsibility: taking into account the impact of one's activities on society and the environment, and adhering to social standards and principles.

The article deals with the investigations of the peculiarities of acquiring values and value orientations by future history teachers and their influence on the process of forming professional competence, which are based on the analysis of philosophical, cultural, psychological, pedagogical, andsocio-pedagogical scientific sources and practice of higher education institutions. It has been proved that the formation of values and, thus, value orientations describe the level of maturity and professionalism of the future history teacher, as well as his/her social activity and creative potential. The author reveals the nature of the value-based component of the process of forming the professional competence of future history teachers in terms of their capability to comprehend and identify values as subjective motives in the process of implementing conscious purposeful learning activities. In this way, value orientations emerge as a certain hierarchy of interests and needs of an individual, according to which certain values are preferred in different life circumstances. In turn, it is determined that the professional orientation of the future history teacher is a crucial factor in the formation of his/her professional competence. Consequently, the formed professional orientation of future history teachers' learning activities in a higher education institution nowadays should be considered as a system of recognised and conscious values and relevant value orientations constructed by personal motives, needs, and interests. In this case, the value-based component of the process of developing the professional competence of future history teachers may be considered from the perspective of its theoretical and content and specific procedural and applied aspects of realisation in the educational process of a higher education institution.

The article deals with the structure and principles of functioning of the university educational environment. Based on the analysis of the concept of environment in its educational context, the main types of environment are identified - social, informational and linguistic. Within the framework of the concept of social environment, its main parameters (social and material) are defined. The informational environment of a higher education institution is presented as a set of three main components - the university's educational policy, management standards and electronic management. The interdependence of the informational and educational environment is noted; the generalized concept is defined as a set of information resources and technologies based on the regulatory framework of a particular country and educational standards adopted for a particular area of training. The language, foreign language and professionally oriented foreign language environment of a higher education institution is analyzed as a powerful factor in the formation of foreign language competence of future specialists.
The categorical and conceptual relationship of the educational environment, educational system and educational space is clarified. The conclusion is made that the educational environment of a higher education institution is a component of the public educational space, characterized by common spatial and educational features, has its own specificity, determined by the possibilities of autonomy and the specifics of subject-subject relations within the university. The leading components of the university educational environment are substantiated - regulatory, socio-cultural, socio-communicative, informational and technological, material and technical. The basic principles of the functioning of the university educational environment are noted: systematic, holistic, humanistic, autonomous, and social responsibility.

The article deals with the main focus of education of student youth in modern conditions. The study and analysis of the fundamental methodological works of well-known Ukrainian and foreign researchers allows us to identify the problematic field of the approach to upbringing in education, which is one of the components of a personality-oriented approach to teaching students and takes into account their individual characteristics. The process of education at university should ensure that prospective specialists acquire both professional competencies and meta-competencies, which include the ability to independently acquire knowledge, analyze, comprehend and generalize it, and transform it into a different «plane of vision». Socio-economic transformations in Ukraine necessitate reforming all sectors of education, which poses new challenges for higher teacher education to improve the effectiveness of theoretical training of perspective teachers as the basis of their professional competence. Among the priority areas of higher education reform are the following: updating the content, forms, and methods of basic teacher education; introducing effective pedagogical technologies; and creating a new system of methodological and information support for higher education. The development and deepening of the theory of pedagogical knowledge is of particular importance for raising the scientific level of perspective teachers’ pedagogical training and its impact on school practice. Modernity requires the education of a person who can make decisions autonomously and independently. The current level of development of society and science requires an in-depth analysis of the problem from the standpoint of the activity of the subject of life itself.

The article based on a holistic analysis of the theory and practice of professional education, describes the theoretical and methodological principles of training perspective primary school teachers to manage and implement educational work with primary school pupils in the New Ukrainian School. It has been established that in the context of the modernisation of the system of higher pedagogical education in Ukraine, there are significant shifts in the directions, content, and essence of primary school teacher training.
The author proves that in the process of studying professional disciplines by future primary school teachers in a higher pedagogical education institution, there is an effective formation and development of their educational competence (professional thinking, emotional intelligence, creative potential, assimilation of educational values and value orientations, experience of social adaptation and socialisation of a growing personality to the challenges and threats of modern Ukrainian society). The elements of such competence are as follows: the knowledge, skills, and practical abilities, experience in designing effective areas of childhood education, communication skills, and abilities to implement, analyse and predict the effectiveness of pedagogical interaction of all participants in the educational process in primary school based on child-centredness, cooperation, co-creation, formed autonomy and responsibility by developing pedagogical thinking, creative activity, and independent improvement of the level of organisation of the educational process in primary school. The article defines and describes the current leading principles of organising and conducting professional training of perspective primary school teachers in the implementation of the strategy of creating an educational process in primary school. There has been highlighted and defined the essence of the basic requirements concerning the content of professional training of perspective primary school teachers for the organisation of educational work in the New Ukrainian School.

The study of the functional asymmetry of the cerebral hemispheres is an important problem of modern science. Teaching that takes into account functional asymmetry can be more effective and contribute to the development of the child’s full potential, including students with special educational needs. It has been proven that school teaching methods are usually focused on the development of the left hemisphere. This is due to the fact that language is the main means of learning at school. In the process of learning, the functional asymmetry increases: the left hemisphere specialises in symbolic operations, and the right hemisphere in figurative ones. However, teaching left- and right-brained students should not be the same. The predominance of left or right brain activity determines the type of thinking a person has, their character, temperament, memory, hand dominance and other psychophysiological features that must be taken into account for effective teaching. To study the peculiarities of the distribution of functional asymmetry of the brain, we selected 14-15 aged students, in which the process of lateralisation is considered to be completed. The results of the study of the coefficient of functional asymmetry of the brain and the type of temperament of 9th grade students of the experimental and control groups are presented. The obtained results correspond to the average world indicators. General recommendations for improving the academic achievements of adolescents with different lateralisation of the hemispheres, taking into account their individual characteristics, in particular the dominant type of temperament. The psychological and pedagogical approaches to the effective implementation of the educational process for right- and left-hemispheric students and ambidextrous students are proposed, which contain methodological recommendations for the selection of forms, methods and means of teaching students, taking into account their functional asymmetry of the hemispheres.
