Published: March 2024

Citizenship education is a relevant issue of education and international policy in many countries, including Lithuania, especially due to the current tense geopolitical situation. In 2022-2023, after updating general education curricula, citizenship education competence is included in all subjects of general education. According to the updated Fundamentals of Citizenship programme for grades 9–10, students can develop citizenship competences by participating in nonformal education and engaging in other activities related to citizenship education. To achieve the aim of the research presented in the article – to analyze the social-educational factors of children’s citizenship education in basic school – an empirical study was carried out, for which the Diagnostic Questionnaire for the Situation of Citizenship Education by Valuckienė et al. (2017) was used. The study made it possible to distinguish the social-educational factors important for citizenship education: the child’s trust in the school staff, the child’s relationship with community events, adults’ respect for the child’s opinion, the child’s interest in news and the child’s participation in school self-government. The results of the empirical study confirmed the hypotheses: 1) respect for the child’s opinion is moderately positively related to the child’s involvement in the life of the school community, participation in school self-government and 2) adults’ respect for the child’s opinion is weakly positively related to the child’s trust in the school staff.

Authors: Kosior Wojciech J.
Published: March 2024

In Roman law there were institutions whose application and, above all, their effects depended on the attainment of a numerically specified age by the subject of the law. Age limits presented in Roman law literature are usually associated with civil law – personal law, and more specifically to the scope of legal capacity, although, of course, a number of other powers exercised under other branches of law were also connected with this capacity. The purpose of this article is to present the results of the research conducted on the juridical sources of Roman law, which revealed texts relating to the problem of age on the grounds of the Roman criminal process. Research conducted on Roman law sources showed that three categories of age were important in the criminal process: 14 years, 20 years and 25 years.

Bezpieczeństwo i porządek publiczny jako wartości konstytucyjne – kilka uwag natury ogólnej po zmianach ustrojowych z lat 90. XX wieku
Authors: Sikorska Agnieszka
Published: March 2024

Bezpieczeństwo i porządek publiczny jako kategorie prawne w demokratycznym państwie prawnym uznawane są za jedne z podstawowych wartości, jakie państwo zapewnia i chroni. Niemniej, są też kategoriami, które stale ewoluują wraz ze zmiennością warunków społecznych, politycznych, norm obyczajowych, prawnych, postępem cywilizacyjnym czy ujawniającymi się zagrożeniami. Wobec tych powodów nie jest możliwe, a nawet celowe ustalenie w sposób jednoznaczny ich treści. Nie wyłącza to jednak równoczesnego dążenia do określenia ich znaczenia normatywnego i zakresu regulacji w przepisach konstytucyjnych, będącego przedmiotem niniejszego opracowania. Wartości te stanowią bowiem podstawę aksjologiczną porządku konstytucyjnego, a jednocześnie stanowiąc integralną część zasad prawa nakazujących ich realizację w tymże porządku, są klauzulą generalną dla wykładni norm ustawowych.
Dostęp osoby bliskiej do dokumentacji medycznej po śmierci pacjenta
Authors: Syroka-Marczewska Katarzyna
Published: March 2024

Nieodłącznym elementem leczenia jest dokumentacja medyczna, która odzwierciedla proces udzielania świadczeń zdrowotnych. Prawo pacjenta do dostępu do dokumentacji medycznej ma fundamentalne znaczenie w opiece zdrowotnej. Przedmiotem opracowania jest analiza regulacji prawnych oraz orzecznictwa dotyczących dostępu do dokumentacji medycznej dla bliskich po śmierci pacjenta. W takiej sytuacji prawo przewiduje możliwość zapewnienia dostępu osobie upoważnionej przez pacjenta za jego życia lub osobie, która w chwili śmierci pacjenta była jego przedstawicielem ustawowym. Co do zasady dokumentację medyczną udostępnia się również osobie bliskiej, chyba że inna bliska osoba sprzeciwi się jej udostępnieniu lub pacjent za życia sprzeciwi się jej udostępnieniu. Sprzeciw pacjenta może zostać uwzględniony w dwóch sytuacjach, tj. w celu dochodzenia odszkodowania lub zadośćuczynienia za śmierć pacjenta oraz w celu ochrony życia lub zdrowia bliskiej osoby. O powyższym rozstrzyga sąd w postępowaniu nieprocesowym. Może on wyrazić zgodę na ujawnienie dokumentacji medycznej i określić zakres jej udostępnienia. W niniejszym artykule przedstawiono analizę przepisów prawa i orzecznictwa w zakresie dostępu osoby bliskiej do dokumentacji medycznej po śmierci pacjenta. Artykuł stanowi także próbę odpowiedzi na następujące pytania: Jakie istnieją możliwości weryfikacji, czy osoba, która zgłosiła się o udostępnienie dokumentacji medycznej zmarłego pacjenta, jest osobą bliską tego pacjenta? Czy upoważnienie ze strony pacjenta do dostępu do dokumentacji medycznej jest wiążące dla wszystkich podmiotów medycznych, czy tylko dla tego, w którym zostało udzielone? Czy prawo pacjenta do dokumentacji medycznej może być postrzegane jako substrat prawa do autonomii/prywatności?

Published: March 2024

The objects of the study are unmanned vehicles and branches of the bridge of the city of Kyiv (Ukraine), which connects the Great Ring Road, Zhytomyr Highway and Peremogy Avenue. The built routes were analyzed using the technology of recognition of road signs, people and vehicles. The important problem of this research is to analyze the possibilities of detecting obstacles by an unmanned vehicle using pattern recognition, which combines the methods of machine communication, navigation and real-time video surveillance.
Based on the study, the results of detecting and avoiding obstacles on the road, where a study was conducted to investigate the main reasons that can cause time delays (traffic jams, weather conditions, accidents). The results of planning and navigation are obtained to determine the appropriate road route, which allows detecting and eliminating obstacles on the road, as well as building a map plan of the route in advance using online map services (Google Maps). It is shown that recognition of road signs (based on the classification using a road sign map consisting of 7 categories), people and vehicles minimizes the occurrence of road accidents, traffic jams and time delays. To recognize the images of road signs, people and vehicles, we studied the road sections connecting to the branched bridge.
Thus, the authors have reviewed and analyzed the digital capabilities of pattern identification and recognition using machine learning methods, navigation and video surveillance systems, where the safety of vehicles with detection of road signs and obstacles on the way is of great importance. The results obtained can complement the possibilities of using unmanned vehicles to avoid obstacles and road accidents based on a trained pattern recognition system. This system, using convolutional neural networks and video surveillance navigation systems, will be able to provide the driver and the people around it with safe driving conditions.

Analysis of the structure of electrically conductive composite ceramics
Authors: Maistat Mykyta , Kryvobok Andrii
Published: March 2024

The object of the research is electrically conductive ceramics. It aims to analyze the microstructure of electrically conductive ceramic composites based on silicon carbide and investigate the influence of silicon carbide content on their properties. This study is pivotal for enhancing materials used in high-tech applications, particularly in fields where distinct electrical insulation and mechanical characteristics are crucial. The microstructure analysis conducted through scanning electron microscopy confirmed the presence of silicon carbide in all examined ceramic samples, except in those where silicon carbide was not added. Special attention should be given to the sample with 30 % silicon carbide, distinguished by the lowest open porosity. These findings are corroborated by previous research where this sample exhibited superior properties: open porosity – 12.51 %, water absorption – 5.88 %, apparent density – 2.13 g/cm³, specific resistance – 0.43·106 Ω·m. These characteristics indicate low porosity and high structural-physical property values. The results not only affirm the successful incorporation of silicon carbide into the ceramic matrix but also highlight the prospects for applying the researched ceramic materials in areas where electrical insulation and mechanical properties are crucial. Specifically, the sample with 30 % silicon carbide appears particularly promising due to its high characteristics and lower porosity, making it potentially interesting for applications in high-tech industries such as electronics and telecommunications. The conclusions suggest the potential use of these ceramic materials in various high-tech industries where both electrical and mechanical properties are essential. The sample with 30 % silicon carbide, with its exceptional characteristics, holds potential for applications in advanced technologies. Further research in this direction could lead to the development of new materials for effective radiofrequency absorption, finding broad applications in different technological fields.

Authors: Vorobiov Iuriy , Maiorova Kateryna , Voronko Iryna , Skyba Oleksandr , Komisarov Oleh
Published: March 2024

The object of research is the process of forming a mathematical model (MM) for calculating accuracy at the stages of construction an analytical standard (AS) using the chain method, the application of which is shown on the example of an aviation object (AO). The analysis of the investigated AO, namely the helicopter stabilizer, was carried out using modern 3D scanners and the creation of its analytical portrait (AP). The problem is to create the most similar AP and compare it with AS, taking into account the results of the calculations. The following results were obtained: the AS was built and the AP of the stabilizer geometry was created, a comparative analysis of the AP and AS was carried out, and the results of the accuracy of the object geometry calculations were obtained. Aerodynamic calculations of stabilizer characteristics were also carried out, analysis of standardized aerodynamic profiles was carried out taking into account the accepted limitations for forming the stabilizer AS. The scientific and practical novelty of the obtained results is as follows: the created MM for calculating the accuracy of the dimensions of the unit contour using the chain method made it possible to estimate the tying errors that occur when using the loft-template method. This made it possible to choose equipment and software for construction the AS stabilizer. The selection of improved values of the object's aerodynamic characteristics made it possible to build an AS based on the standardized NACA 0012 profile. This can be used as an information basis for the organization of small-scale production of the object under study. That is, in general, the process of reverse engineering made it possible to conduct a detailed analysis of sections, aerodynamic characteristics and improve them for the future improved profile. This design approach provides wider opportunities, eliminates intermediate links and maintains high accuracy of object parameters during its manufacture, which is one of the main requirements in aircraft construction.

2022 and 2023 are considered the most conflictual years of the Cold War. The confrontation between Israel and Hamas, the escalation of tensions between Serbia and Kosovo, Sudan, Yemen, Karabagh are some of the hot spots that threaten the stability of peace and the world-class economy. 183 armed conflicts were counted for 2023, which is the highest figure for 30 years, and military aggression on the territory of Ukraine has reached the most destructive scale. Research work is an attempt to create a multipolar world, thanks to scientific activity due to the consequences of armed conflicts on the territory of Ukraine.
The most important condition for economic growth on the platform of quality renewal of production is the reduction of costs, the production of a quality product, service, and the introduction of innovation. Thus, the object of the study is the dependence of targeted financing of innovations as a direction that will contribute to increasing the level of innovative development of enterprises. It also considers the dependence of targeted financing of innovations as a way to increase the level of innovative development of enterprises under the known impact of military operations on the territory of Ukraine. The problem of the research is the state of innovative development of Ukraine, the factors that caused it, the tools of influence and stimulation from the state, such as tax incentives, attracting investors for the development of small and medium-sized businesses through the creation of favorable economic conditions, using the example of the Diia City tax regime. It also the dependence of targeted financing of innovations, as a direction to increase the level of innovative development of enterprises under the known effects of military actions on the territory of Ukraine. The obtained results are due to such factors as the impact of military aggression on the territory of Ukraine, the pandemic and post-pandemic period, which had negative consequences such as a decrease in the planned volume of production due to the downtime of enterprises, a decrease in labor productivity, changes in the established raw material supply system. The study of the special regime of «Diia City» indicates a positive growing level of interest of investors, in particular foreign ones, in attracting funds for the development of various sectors of the economy, most of all in the field of information services, which contributes to the processes of digitization and integration of Industry 4.0. The results can be used for the strategic planning of economic entities during the war period and the post-war recovery of the economy of Ukraine, where the attraction of innovations is one of the key elements of economic prosperity, and tax incentives are a tool of the state regulatory apparatus.

The object of the research of the article is transport system of a city. The paper reviews the necessity to assess the greenhouse emissions in the city and proposes the methods for greenhouse emissions inventory of the urban transport system. The proposed approach is aligned with guidelines for the development of Sustainable Energy and Climate Action Plan (SECAP) of Mayor Covenants of European Union (EU). The methodologies outlined in the paper allow to estimate annual greenhouse emissions from transport sector.
The SECAP defines transport sectors based on ownership and functioning as following: municipal transport fleet, public transport, and private and commercial transport. The paper proposes the methodology to estimate direct and indirect emissions in each of the described sector based on the information that is typicaly available to municipalities in Ukraine. The assessment is conducted on disaggregated level for different fuel types (diesel, petroleum, natural gas, biofuel, electricity, etc.) and separately for each fleet type (buses, trucks, passenger vehicles, specialized machinery). Total CO2 emissions are then estimated by multiplying the amount of fuel consumed by the emission factor for each fuel type and vehicle type. Information of fuel consumption is estimated based on annual milage and estimated based on available data and number of assumptions proposed in the paper. The proposed methodology for greenhouse emissions inventory for the transport sector allows to analyze available data, recommendations for data collection and a methodology for determining CO2 emissions from the operation of the transport system with sufficient accuracy of calculations.
Based on these results, it is possible to forecast changes in energy consumption and emissions in the transport sector as a result of various interventions. For example, in Zhytomyr city the results of inventory were used to develop a set of measures, which include updating the rolling stock of electric transport; increasing the energy efficiency of the power grids of the transport system, developing cycling infrastructure.
The enhancing energy efficiency in hyperthermia treatment: a frequency-reconfigurable L-Shape antenna design and analysis
Authors: Akinola Segun , Leelakrishna Reddy
Published: March 2024

The object of research is a frequency-reconfigurable L-Shape antenna. This paper presents an innovative study focusing on the design and analysis of a frequency-reconfigurable L-Shape antenna with a specific application in Hyperthermia Treatment. The antenna, operating in the frequency range of 2.5 to 8 GHz, utilizes a varactor to achieve agility and simplify design, thereby reducing component count. Constructed with a Roggers RT5880 (lossy) substrate, the L-Shape configuration ensures optimal performance. The incorporation of a single varactor, acting as a junction capacitance, not only enables straightforward tuning but also contributes to enhanced energy efficiency by reducing overall power consumption in the reconfigurable antenna system. The study employed CST Microwave Studio's 3D Electromagnetic field simulation software for time domain solver-based simulations, with validation conducted using the frequency domain solver. Results from the simulations showcase the antenna's performance at different frequency states.
At the tuning state frequency of 2.7 GHz, the antenna exhibits an impressive gain of 1.905 dB and a directivity of 7.530 dB. Similarly, at the tuning state frequency of 6.89 GHz, the gain is measured at 6.806 dB with a directivity of 7.490 dB. The proposed L-Shape antenna design not only demonstrates significant potential for Hyperthermia Treatment, allowing targeted heating within the 2.5 to 8 GHz frequency range but also aligns with the multidisciplinary focus of medical science. This contribution reflects the commitment to advancing medical science through original research, fostering innovation, and promoting energy-efficient solutions with practical applications in clinical settings.
Improvement of the methodology for predicting gas-dynamic phenomena on the basis of modern sound-capturing equipment
Authors: Krasnyk Vyacheslav , Deglin Boris
Published: March 2024

The object of the study is the sound accompaniment of the processes of stress redistribution in the bottom part of the coal seam, which precede the release of rock, coal, and gas. Among the hazards of underground coal mining, gas-dynamic phenomena (GDP) are the most complex in nature and the most dangerous in terms of consequences of high dynamic power and the release of a large amount of mechanical energy in the form of fractures and gas in a short period of time. This leads to accidents due to sudden gassing and blockages of workings with coal and rock, as well as explosions of methane and coal dust, destruction of the workings' support, damage to machinery and mechanisms, equipment, and devices. The greatest hazard among GDPs is posed by sudden releases of coal and gas, rock and gas, gas releases with destruction of host rocks and with destruction of the ground of the workings, as well as gas breakthroughs from tectonic fault zones.
Therefore, the accuracy of predicting possible gas-dynamic phenomena significantly affects the level of safety of miners. The acoustic emission (AE) method is used to predict the gas-dynamic activity of a rock massif. The analysis of acoustic emission studies based on archival data in coal seams subject to gas-dynamic activity has made it possible to substantiate the possibility of improving the accuracy of the forecast of emission hazard, which has a social and economic effect. On the basis of exploratory research and production tests, the software for automated calculations of the GDP forecast was improved and an improved Methodology for forecasting gas-dynamic phenomena based on modern sound-capturing equipment was developed. A scientific justification for the reference interval of AE observations in the conditions of a particular longwall was developed.
The developed software and the forecasting methodology were tested in the conditions of the Tsentralna mine of the Toretskugol State Enterprise (Toretsk, Donetsk region, Ukraine). The practical significance of the work is that a method for predicting explosion hazard has been developed, taking into account the modern capabilities of equipment and methods of input data processing, which allows to increase the productivity of mining and tunneling operations in coal seams without reducing the safety of miners.

Authors: Sieun Sieun , Kim Seung Kyum
Published: March 2024

PURPOSE: Although research on hypertension and physical activity has expanded in the past few decades, an attempt has yet to be made to characterize the published landscape on this research topic. This study aimed to evaluate research trends in hypertension studies to which physical activity was applied as a lifestyle modification.METHODS: Articles containing two keywords, ‘hypertension’ and ‘physical activity’, were used to search Web of Science, PUBMED, and SCOPUS for articles published from January 2000 to June 2023. After trimming, a total of 2,042 publications were chosen for bibliometric analysis.RESULTS: Over time, a gradual growth in the number of publications was observed. The findings of bibliometric analysis suggest that research on this topic is more active in developed countries than in their developing counterparts. Our findings demonstrate that chronic disease complications, such as ‘diabetes’, ‘obesity’, and ‘cardiovascular disease’, were the most popular research agendas associated with hypertension and physical activity.CONCLUSIONS: Our findings indicate that ‘physical activity’ has become an important keyword in not only hypertension, but also hypertension-associated complex diseases. More scholars from various backgrounds and geographical regions, in particularly developing countries, are expected to join the discussion on hypertension and physical activity.
