Nieuczciwa konkurencja w aspekcie wielkich wydarzeń sportowych
Authors: Wolski Dominik
Published: December 2024

Wielkie wydarzenia sportowe, do których zaliczyć można w szczególności mistrzostwa kontynentów oraz igrzyska olimpijskie i paraolimpijskie posiadają ogromny potencjał ekonomiczny. Potencjał ten jest wykorzystywany przez przedsiębiorców, w tym reklamodawców i sponsorów. Jednym z elementów prowadzonej w tym obszarze rywalizacji są także takie działania podejmowane przez przedsiębiorców, które mogą być kwalifikowane jako przejawy nieuczciwej konkurencji. Celem niniejszego artykułu jest omówienie najbardziej charakterystycznych działań podejmowanych w tym zakresie przez przedsiębiorców, co w szczególności dotyczy marketingu i reklamy oraz sponsoringu. Zagadnienia te omówione zostały na tle przepisów dotyczących zwalczania nieuczciwej konkurencji. W rezultacie przeprowadzonych rozważań oraz przeanalizowanych w tym zakresie przejawów nieuczciwej konkurencji, w opinii autora nie jest konieczna interwencja prawodawcy. Obowiązujące regulacje prawne charakteryzujące się znaczną elastycznością, należy uznać za wystarczające do zapobiegania ewentualnym czynom nieuczciwej konkurencji, także tam gdzie przedsiębiorcy działają w sposób niestandardowy.

Potencjalna rola regulacji soft-law i francuskiej koncepcji rozporządzeń z mocą ustawy (ordonnances) w osiąganiu celów zrównoważonego rozwoju
Authors: Mariański Michał
Published: December 2024

The purpose of the article is to present the interconnection between the financial market, sustainable development and soft-law rules in today’s economy we have an overlapping process in the financial markets between general investment based on financial efficiency and investment concerning social responsibility – including ESG criteria (environmental-social-governance). The concept of sustainable development may be defined as a tool leading not only to economic growth but in the long term also as a solution leading to the elimination of the disproportions and instabilities within a society. The COVID pandemic and the war in Ukraine showed, that today we require some new legal instruments and techniques that could help in the realization of goals of sustainable development and that would ensure legal stability. The methodology used by the author is related to the functional approach of the comparative legal method, the historical-descriptive and the dogmatic method, with a special focus on French and international law regulations. Comparative method is both a science, a research method and the effects of research obtained from the application of the comparative studies. Comparative studies, as a science of comparing selected aspects of different legal systems, is aimed at learning and understanding law in a much broader context, because at the supranational level. It is this aspect that makes comparative research extremely important for sustainable development rules, which are often characterized by a cross-border and international character. The scientific aim of the work is to show whether and how soft important law provisions especially in the financial market, as well as regulations with the force of law, can be a useful instrument supporting the process of building sustainable finance. As part of the conclusions, the author notes that the use of the described legal structures may contribute to faster and more effective implementation of sustainable development regulations. The above is even more important when these regulations appear from a supranational perspective rather than from a national perspective.

Authors: Shaikh Sheeraz Ilyas , Pathan Saifullah , Laghari Ibarat Ali
Published: December 2024

Sports provide a space for recreation and emotional growth, where mental well-being, life satis-faction, and aggression often intersect. Mental well-being fosters resilience, while life satisfaction reflects overall contentment. Objective of the present study was to investigate the relationship between aggression and mental well-being and predictive relationship of mental well-being with life satisfaction. Sample comprised of 300 males, 21 to 34 years old, recruited through conven-ient sampling technique from Sindh, Pakistan. Data was collected using DIQ, BPAQ, SWLS and WEMWBS. Findings show life satisfaction was significantly predicted by mental well-being (r2 = .10, F = 32.94, p <. 05), emotional intelligence (R2 = .37, F = 129.16, p < .05), and negative relationship between aggression and life satisfactory (r = -.113, p = <. 05). The study encourages the integration of targeted interventions that can help reduce aggression and enhance positive mental states, ultimately contributing to healthier, more satisfied communities.
Ujawnienie danych osobowych zawiadamiającego o przestępstwie kościelnym. Kazus i jego rozwiązanie
Authors: Andrzejewski Maciej , Kroczek Piotr
Published: December 2024

Kanwą dla zawartych w niniejszym artykule rozważań jest kazus, w którym parafianie donieśli na swojego proboszcza o rzekomym naruszeniu prawa kanonicznego poprzez prowadzenie przez niego życia w konkubinacie. Oskarżenia okazały się nieprawdziwe i domniemana konkubina zażądała od biskupa diecezjalnego ujawnienia tożsamości zawiadamiających. Celem artykułu jest odpowiedź na pytanie: czy można ujawnić dane osobowe zawiadamiającego o przestępstwie kościelnym osobie, której zawiadomienie dotyczy, lub innym osobom. Badając to zagadnienie, należy wziąć pod uwagę zarówno prawo kanoniczne, w tym dekret ogólny Konferencji Episkopatu Polski o ochronie danych z 2018 r., jak i przepisy prawa powszechnie obowiązującego regulujące ochronę danych osobowych (polskiego i europejskiego, w tym RODO oraz przepisy chroniące dobra osobiste). Szukając odpowiedzi na postawione pytanie, autorzy posługują się metodą dogmatyczno-prawną w celu precyzyjnego ustalenia treści norm prawnych dotyczących ochrony danych osobowych oraz metodą komparatystyczną, porównując zakres ochrony danych osobowych w porządku prawnym Kościoła Katolickiego i Rzeczypospolitej Polskiej. Analizie poddają przesłanki warunkujące dopuszczalność ujawniania danych osobowych w kontekście posiadania przez wnioskodawcę interesu faktycznego i prawnego. Z przeprowadzonych analiz wynika, iż ani interes faktyczny, ani interes prawny o charakterze duchowym nie są wystarczające do ujawnienia danych. Podstawą do tego może być tylko interes prawny materialny wnioskodawcy. Zgodnie z zaproponowanym sylogizmem biskup diecezjalny, ustalając z moralną pewnością, że wnioskujący ma interes prawny materialny, a donos był nieprawdziwy i dokonany w złej wierze, powinien stwierdzić, że zawiadamiający nie cieszy się ochroną i ujawnić jego dane zgodnie z wnioskiem.
Non-state pension funds of religious organisations in Ukraine: Background and factors of influence
Authors: Bilash Oleksandr , Karabin Tetyana , Patskan Valeriy
Published: December 2024

In this article, an attempt is made to reveal the prerequisites for and factors influencing the participation of religious organisations in establishing non-state pension funds in Ukraine. This study is based on the current regulatory framework, economic indicators, and information regarding the practical activities of the only non-state pension fund established by a religious organisation in Ukraine. Moreover, this study analyses the legal, ethical, security, economic, and corporate prerequisites for and factors that influence the formation and operation of church pension funds.
In general, the conditions for the development of non-state accumulative pension funds in Ukraine are unfavourable; this is due to the high level of inflation, the backwardness of the financial institutions in the country, and the public distrust of these institutions. However, the positive factors influencing the development of pension funds established by religious organisations include the high performance of the “Pokrova” church fund, the stability of church institutions (which can become a benchmark for citizens in their attitude towards institutions established by religious organisations), and the interest of clergy and religious organisations themselves in the accumulation of clerical pensions (either in addition to the state pension or instead of it).
Despite the fact that the practice of establishing such funds is not widespread, they deserve more attention from the state, as they fulfil an important social function - the provision of pension for a specific person (whether a believer, a clergyman, or any other person).

Authors: Patel Durga Prasad , Bhagat Shashikala , Madhukar Somprabha , Kashyap Princy , V. R. Ravikumar
Published: December 2024

Aim: This study aims to investigate the binding affinity and interaction mechanism of Yakuchinone B, a bioactive diarylheptanoid, against key inflammatory targets, including Cyclooxygenase-1 (COX-1), Cyclooxygenase-2 (COX-2), 5-Lipoxygenase (LOX-5), and Thromboxane A2 (TXA-2), using a molecular docking approach. Methodology: A molecular docking study was performed using Schrodinger software. The 3D structure of Yakuchinone B was optimized, and the crystallographic structures of the inflammatory targets were retrieved from the Protein Data Bank (PDB). Docking simulations were executed to evaluate binding energies, interaction profiles, and amino acid residues involved in target inhibition. Comparative analysis with standard anti-inflammatory drugs was conducted to assess Yakuchinone B’s relative efficacy. Results: Yakuchinone B exhibited significant binding affinities with all four inflammatory targets, with the highest docking score observed against COX-2, indicating potential selectivity. The analysis revealed critical hydrogen bonding, hydrophobic interactions, and π–π stacking with essential amino acid residues of the active sites. The binding energies of Yakuchinone B were comparable to or better than those of standard anti-inflammatory agents, highlighting its competitive potential as a multi-target inhibitor. Conclusion: The molecular docking analysis demonstrates Yakuchinone B’s strong binding affinity and multi-target inhibitory potential against COX-1, COX-2, LOX-5, and TXA-2. These findings support further in vitro and in vivo investigations to establish its role as a promising anti-inflammatory agent, thereby promoting its development as a novel therapeutic candidate.

Published: December 2024

The effect of N-acyl derivatives of 2-amino-4,6-di-tert-butylphenolon the functions of neutrophils was studied. It has been established that these derivatives with a free hydroxyl group in the benzene ring, in contrast to O-methylated ones, modify the properties of cells, which is expressed in a decrease in hypochlorous acid generation during the “respiratory burst” formation. These compounds are scavengers of HOCl/OCl– generated by activated neutrophils and reduce the secretion of myeloperoxidase (MPO) from cells. N-(3,5-di-tert-butyl-2-hydroxyphenyl)acetamide has been shown to be the most effective hypochlorous acid scavenger. This substance significantly suppresses the secretory degranulation of neutrophils and has a cytoprotective effect under conditions of halogenating stress.

Authors: Salimov D. F. , Bogolyubova I. O. , Bogolyubov D. S.
Published: December 2024

Although in vitro fertilization (IVF) programs usually use mature (metaphase II, MII) oocytes, it is also possible to use diplotene oocytes at the germinal vesicle (GV) stage after their in vitro maturation (IVM). Morphological characteristics of native GV oocytes are promising predictors their capacity of spontaneous maturation in stimulated cycles. The purpose of this work was to analyze the patterns of cytoplasmic granulation of GV oocytes that differ in their ability to resume and complete meiotic maturation in vitro. It has been shown that the central granulation pattern negatively correlates with the ability of GV oocytes to spontaneously mature in vitro.

Authors: Serebryakova O. N. , Ivanova V. V. , Milto I. V.
Published: December 2024

Preterm birth can contribute to the development of diseases of circulatory system in adulthood due to the incompleteness of the morphogenesis of the blood vessels wall. Smooth muscle cells are the leading cell population in the middle shell of the aortic wall and are plastic in nature, i. e. they are able to change their phenotype depending on the conditions of their environment. The presence of synthetically active smooth muscle cells in the aortic wall of an adult individual is a predictor of the formation of a wide range of cardiovascular diseases. The aim of our study is to identify the morphofunctional features of molecular phenotype and ultrastructure of smooth muscle cells of ascending aorta wall in rats born 12 and 24 hours prematurely. The paper presents the results of immunohistochemical and morphometric, as well as ultrastructural analysis of ascending aorta wall in Wistar rats born 12 and 24 hours prematurely. It has been shown that preterm birth leads to a later change in the phenotype of smooth muscle cells from synthetic to contractile, which can negatively affect the morphofunctional state of the cardiovascular system.

Since the dawn of humanity, human beings have inherently sought a state of security, trying to make their existence as comfortable as possible. Accordingly, among the many factors affecting human health, comfort and well-being, the quality of the micro-environment and ecology, as well as the health care system and health-saving resources, are important. In this regard, environmental security, with its systemic nature, brings a significant contribution to the PPM model by optimizing the state of balance in the interrelationship of natural, anthropogenic, physiological and social processes. Accordingly, individualized nutrition and pharmacointervention for preventive and prophylactic purposes, being important tools for health preservation, represent an integrative approach aimed at understanding the interaction between nutrition and the environment within the formed or formed lifestyle. This review will consider the main components of human health protection, as well as their impact on the preservation of ecobiocenosis stability.

Published: December 2024

The formation of adducts of tellurium(IV) 3,6-di-tert-butyl catecholate (Te(Cat36)2) with N-methylpyrrolidone (NMP) is studied. The crystallization from a CH2Cl2–NMP–aromatic hydrocarbon mixture is found to result in the formation of dimeric complexes [{Te(Cat36)2}2(μ-NMP)(μ-arene)] (arene = C6H6, C7H8), whereas mononuclear [Te(Cat36)2(NMP)2] is formed from a CH2Cl2–NMP–alkane mixture. The formation of the adducts with aromatic hydrocarbons indicates a possibility of using the tellurium complexes for the separation of hydrocarbon mixtures, including an industrially important benzene–cyclohexane mixture.

Published: December 2024

In an attempt to synthesize a new iminomethylphosphine, tBuC(Ph2P)=N-Btd (Btd = 2,1,3-benzothiadiazole) by a three-step procedure including (1) NH2-Btd + tBuC(=O)Cl → tBuC(=O)NH-Btd; (2) tBuC(=O)NH-Btd + SOCl2 → tBuC(Cl)=N-Btd; (3) tBuC(Cl)=N-Btd + Ph2PSiMe3 → tBuC(Ph2P)=N-Btd, it was found that the second step is accompanied by the chlorination of the carbocycle in the benzothiadiazole moiety. The reaction of the imidoyl chloride tBuC(Cl)=N-(7-Cl-Btd) formed in this reaction with Ph2PSiMe3 gave 1,3-iminomethylphosphine tBuC(Ph2P)=N-(7-Cl-Btd) (PC=N). The byproducts formed in this step include 1,3-aminomethylphosphine oxide tBuC{Ph2P(O)}NH-(7-Cl-Btd) (POCN) and (Ph2POx)2,, resulting from partial oxidation and hydrolysis. The reactions of PC=N and POCN with [Pt(COD)Cl2] (COD = 1.3-cyclooctadiene) were studied. In the case of PC=N, the reaction affords the [Pt(PC=N)2Cl2] complex. In the latter case, cleavage of the P–C bond in POCN takes place, and [PtCl2(Ph2POH)2](POCN) and [Pt(CH3CN){tBuC-NH-(7-Cl-Btd)}Cl]. are isolated from the reaction mixture. The structures of the new compounds were established by single-crystal X-ray diffraction (tBuC(Cl)N-(7-Cl-Btd)), 2335152 (POCN · Et2O), 2335149 (Ph2POx)2, 2335153 ([Pt(PC=N)2Cl2]), 2335154 ([PtCl2(Ph2POH)2](POCN)), 2335151 ([Pt(CH3CN)(tBuC-NH-(7-Cl-Вbtd))Cl]).

A series of mononuclear complexes [Ln(Py3PO)2(NO3)3] · 1.5Me2CO (Ln = Sm, Eu, Gd, Tb, Dy) and [Ln(Py3PO)(TTA)3] (Ln = Eu, Tb; TTA‒ is thenoyltrifluoroacetonate ion) based on tris(2-pyridyl) phosphine oxide (Py3PO) is synthesized and studied. In the synthesized compounds, Py3PO acts as the N,O-chelate ligand resulting in the formation of coordination polyhedra N2O8 and NO7 of the Ln atom in complexes [Ln(Py3PO)2(NO3)3] · 1.5Me2CO and [Ln(Py3PO)(TTA)3], respectively. The complexes of Sm3+, Eu3+, Tb3+ and Dy3+ ions exhibit lanthanide-centered photoluminescence in the solid phase at 300 K. The energy of the T1 triplet level of Py3PO is determined to be 21 900 cm‒1 from the ligand-centered phosphorescence spectrum of the Gd(III) complex at 77 K. Among the complexes with the NO3‒ ions, Py3PO exhibits the highest sensibilizing ability toward Tb3+, whereas the ligand environment in the complexes with the TTA‒ ions most efficiently sensibilizes the Eu3+ ion luminescence.
On the structure of temperature pulsations near the surface under convective conditions
Authors: Malinovskaya Е. A. , Chhetiani O. G. , Azizyan V. G.
Published: December 2024

Measurements of temperature pulsations under conditions of summer hot weather in the near-surface air layer in a deserted area were carried out using wire sensors distributed spatially and in height with a recording frequency of 1000 Hz. For the power spectra, slopes with values from “–1” to “–1.35” (scale: 0.2–2 m) are noted for frequencies below the “–5/3” inertial interval region. At frequencies above the inertial interval (scales: 0.01-0.1 m), slopes range from “–4.2” to “–5.8”. In some episodes at frequencies less than 0.1–0.3 Hz, slopes from “–0.2” to “–0.85” are observed. Based on the equations of motion in the Boussinesq approximation, we obtained estimates for the observed slopes of the spectra: “–1”, “–4/3”, and “–7/3”, characteristic of a thermally stratified medium. Using a qualitative (visual) method at different signal averaging times (1, 10, 200 s), the occurrence of thermoconvective structures of “ramps” with a temporal length of 0.3–1 s was revealed, which constitute ramps with a length of 1–10 s at larger averaging.
Second-Order Steady Forces on a Ship Advancing in Waves
Authors: Fang Ming-Chung
Published: December 2024

The nonlinear forces, including the ‘mean’ drifting forces and added resistance, exerted on a ship advancing in regular waves are formulated in the paper. Neglecting the second-order potential, the first-order one is used to calculate the second-order forces which are expressed as products of the radiation potential, diffraction potential, the incident wave potential, and the ship motion response. Based on the well-developed strip theory, the first-order potentials of each ship section are derived by source distribution method and the related first-order ship motion responses are also obtained. Several wave headings and ship speeds are considered. Comparisons are made with other theoretical results and some experimental data and good agreements are generally obtained. It is also found that the second-order forces obtained based on the present strip theory are generally better than those obtained by other methods.
Finite Element Shaft Alignment on Elastic Foundation
Authors: Deliporanides G.
Published: December 2024

Increased ship dimensions and installed propulsion power require still heavier shaft systems. As a consequence, in a shaft alignment process, even higher accuracy has to be achieved. A serious problem in a shafting system comes from the fact that less bearings lead to high bearing pressures and thus to higher deflections due to elasticity of the bearing foundation. The elasticity of bearings is rarely accounted for because of the complications it implies both in its simulation through a stiffness coefficient and in treating the resulting differential equation. A FE (Finite Element) code capable of being applied on a personal computer has been developed in order to deal with the alignment of main propulsion shafting systems.
Structural Safety and Fatigue of Ships
Authors: Nibbering J.J.W.
Published: December 2024

The high stress level in ships – largely due to the use of higher strength steels – has made fatigue a major problem for ship-owners and classification societies. It will be discussed that fatigue cracks are not merely a nuisance (leakage and repairs), but that they constitute a and probably the main danger for the safety of ships against (brittle) fracture. It is doubtful whether sophisticated fatigue and reliability calculations are of much use in this respect. Rather they may give a false feeling of safety. Better design of details and especially improved workmanship (welding), are more valuable. Examples will be given.
Performance of Chordwise Flexible Oscillating Propulsors Using a Time-Domain Panel Method
Authors: Bose N.
Published: December 2024

A two-dimensional time-domain constant potential panel method was used for analysis of chordwise flexible oscillating hydrofoils as oscillating propulsors. The oscillatory motions as well as the chordwise deflections were of large amplitude. Results are presented of propulsive thrust coefficient and efficiency over ranges of motion parameters including varied reduced frequency, pitch amplitude and feathering parameter; heave amplitude/chord ratio; pitching axis position; phase between pitching and heaving motions; and deflected shape. The ranges were taken about a favourable operating point for a flexible oscillating NACA 0012 foil. A peak in propulsive efficiency was found for each motion parameter variation studied. Propulsive efficiency varied strongly with changes in heave amplitude/chord ratio, pitch amplitude and phase between heaving and pitching motions, but less strongly for variations in pitching axis position and flexibility.
Parametric Identification of Manoeuvring Models for Ships
Authors: Haddara Mahmoud R. , Wang Yie
Published: December 2024

Time domain simulation techniques are becoming a widely accepted tool for the evaluation of controllability and manoeuvring performance of conventional surface ships. Different simulation packages are available on a commercial basis. The accuracy of predictions obtained using these models are largely dependent on the level of accuracy in estimating the values of the parameters used in these models. Several methods are available for the determination of the values of these hydrodynamic parameters. However, each one of these existing methods has its own shortcomings. In this paper a new predictive method is outlined for the estimation of the hydrodynamic characteristics for a ship performing certain standard manoeuvres. The method uses neural networks technique to predict the hydrodynamic parameters of the ship. Parameters normally measured during standard manoeuvre e.g. surge, sway and yaw velocities and rudder angle, will be used as input to the predictive model. The first author has successfully used the same technique in predicting the transverse stability of a ship at sea.

The effects of localized imperfections on the collapse strength of plates are studied by means of finite element analysis performed by different authors. First a benchmark study is performed to assess the accuracy of the results obtained using different codes on the same case study. Afterwards, a parametric study on the effect of the localized imperfections on the collapse strength is performed. Finally, the effect of combining local and global imperfections was studied. It is found that the addition of a localized imperfection changes the collapse strength of the plate, which depends on the amplitude and size of the localized imperfection change.
Simulating the collision response of ship side structures: A failure criteria benchmark study
Authors: Ehlers Sören , Broekhuijsen Joep , Alsos Hagbart S. , Biehl Florian , Tabri Kristjan
Published: December 2024

Simulations of the collision response of three different ship side structures are performed using the finite element method. The aim is to obtain a force–penetration curve based on the inner mechanics without considering outer dynamics. Respective structures were previously tested in large scale under the right angle ship–ship collision with a bulbous bow and these experiments were used to validate the simulations. The analysis focus is to determine the influence on the collision results from different failure criteria including the mesh size sensitivity. This paper applies the Germanischer Lloyd (GL) criterion based on thru thickness plastic strain, the criterion based on studies of Peschmann and the Rice–Tracey and Crockcroft–Latham (RTCL) criterion. The comparison of results attained here with the experimental results brings an insight into the sensitivity of the failure criteria. The final conclusion of this work is the performance of the studied failure criteria and further guidelines for collision or grounding simulations.

Published: December 2024

The problem of ship rolling in the stochastic wave has been studied in the past. In this paper the stochastic nonlinear dynamic behaviors including stochastic chaotic motion and probability density function of ship rolling are studied by nonlinear dynamic method and probability theory. The random Melnikov mean-square criterion is used to determine the parameter domain for ship's random chaotic motion. The probability density function of rolling response is evaluated in the chaotic parameter domain using path integral method. The time-dependent probability of ship rolling restricted within the safe domain is provided and capsizing is investigated in the probability's view.
Self-propulsion testing study of a four-propeller vessel
Authors: Bi J.Y. , Zong Z. , Fu G.N.
Published: December 2024

A series of model self-propulsion tests are designed by orthogonal optimization method in order to discuss the propulsive performance of a four-propeller model. The research on propulsive performance includes propulsive efficiency, axial thrust and shaft torque. Axial thrust and shaft torque are got from self-propulsion experiments, and propulsive efficiency of every propeller is calculated based on five parameters measured in self-propulsion tests and resistance tests, respectively. After testing and calculating, the percentages of propulsive performance are obtained to analyze four-propeller arrangement. Five factors with different levels are confirmed in the orthogonal experimental design. By changing transverse positions and longitudinal positions with three levels and rotation directions of four propellers with two levels, propulsive performance of each propeller would change obviously. Three ways are performed to analyze experimental results and discuss the influencing factors. The optimum combination of five factors with different levels is obtained by analyzing the effect of four-propeller arrangement. And the major factor is found according to the order of magnitude of five factors. Depending on all analyses, the optimum arrangement of propeller positions and rotation directions is acquired to distribute four propellers in the wake of the model hull.
The contribution of the engine room structure to the hull stiffness of large container ships
Authors: Senjanović Ivo , Vladimir Nikola , Tomić Marko
Published: December 2024

Very large container ships are rather flexible due to their large deck openings. Hydroelastic stress analysis is therefore required as a base for reliable structural design. In the early design stage, the coupling of the beam model with a 3D hydrodynamic model is rational and preferable. The calculation is performed utilizing the modal superposition method, so natural hull modes have to be determined in an appropriate way. Consequently, the advanced thin-walled girder theory, which takes the influence of shear on both bending and torsion into account, is applied to calculate the hull flexural and torsional stiffness properties. A characteristic of very large container ships is the quite short engine room, whose closed structure behaves as an open hold structure with a shear centre outside the cross-section, very close to that of the open section. As a result, torsionally induced horizontal bending is negligible, while the distortion of the cross-sections appears as a new problem. The task is solved by an energy balance approach that enables the use of effective stiffness. Hence, the effect of interior decks is taken into account by increasing the torsional stiffness of the open cross-section within the engine room domain. The procedure is checked by the 3D FEM analysis of a ship-like pontoon. Such a modified beam model of the engine room structure can be included in the general beam model of a ship hull for the need of hydroelastic analysis, where only a few first dry natural frequencies and mode shapes are required. For practical use in the preliminary design of ship structures, the simplicity of the beam model presents an advantage over 3D FEM models.

BACKGROUND: Hypertension is a critical global health challenge, closely interlinked with obesity, insomnia, and psychological distress. In Bangladesh, rising urbanization and lifestyle changes exacerbate these conditions, yet limited research has explored their combined impact, particularly among hypertensive patients. This study investigates the interconnections between psychological distress, obesity, and insomnia among hypertensive patients in Bangladesh, aiming to identify risk factors and inform interventions for holistic health management. 

METHODS: A cross-sectional study was conducted from September to December 2024, involving 739 hypertensive patients aged 18 and above. Data collection utilized a Personal Information Form, the Bengali Kessler Psychological Distress Scale (K6), and the Bangla Insomnia Severity Index (ISI). BMI was calculated from self-reported weight and height. Data were analyzed using SPSS, employing descriptive statistics, chi-square tests, and regression analyses to examine associations. 

RESULTS: The majority of participants (65.1%) experienced moderate psychological distress, with severe insomnia reported by 8.5%. Significant associations were found between psychological distress and socioeconomic status, education, and urban-rural residency (p < 0.05). Obesity and insomnia were strong predictors of distress, creating a bidirectional relationship. 

CONCLUSION: Psychological distress significantly influences obesity and insomnia in hypertensive patients, highlighting the need for integrated mental health and lifestyle interventions. Addressing socio-economic and demographic disparities is critical for effective hypertension management in Bangladesh.
СТАНОВЛЕННЯ СОЦІОЛОГІЇ РЕЛІГІЇ ЯК ГАЛУЗІ УКРАЇНСЬКОГО АКАДЕМІЧНОГО РЕЛІГІЄЗНАВСТВА: РЕТРОСПЕКТИВНИЙ ПОГЛЯД
Authors: Бучма Олег Васильович
Published: December 2024

У статті на основі ретроспективного екскурсу в історію українського релігієзнавства розкриті особливості становлення соціології релігії в Україні. Показано її теоретичне й емпіричне соціологічне та релігієзнавче підґрунтя, зокрема наголошено на значенні наукових здобутків західноєвропейських учених (О. Конт, Е. Дюркгейм, Г. Спенсер, М. Вебер та інші). Встановлено, що ключову роль у формуванні соціології релігії в Україні, саме як міждисциплінарної (релігієзнавчої та соціологічної) галузі наукового знання, відіграли українські вчені (академічні релігієзнавці) та відділення релігієзнавства Інституту філософії імені Г.С. Сковороди Національної академії наук України. На прикладі співпраці вчених-релігієзнавців, викладачів і студентів (які набували досвіду роботи соціолога-релігієзнавця, що практикує) показано осмислення релігії як соціального феномену у тріаді «студент – викладач – учений». Визначено, що вагоме місце у процесі становлення соціології релігії в Україні посідала спеціалізована вчена рада Д 26.161.03 із захисту дисертацій на здобуття доктора (кандидата) наук за спеціальністю 09.00.11 – релігієзнавство (у галузі філософських, історичних і соціологічних наук). Виснувано, що завдяки внеску українських академічних релігієзнавців соціологія релігії утвердилася в науковому академічному просторі України.
РИМО-КАТОЛИЦИЗМ В УКРАЇНІ: ЕТНОКОНФЕСІЙНИЙ ВИМІР ІСТОРИЧНОГО РОЗВИТКУ (ЧАСТИНА 1. ВІД ПОЧАТКІВ ДО 30-Х РОКІВ ХІХ СТОЛІТТЯ)
Authors: Надтока Геннадій Михайлович
Published: December 2024

У статті, яка є першою частиною розлогого дослідження етноконфесійного виміру історії Римо-католицької церкви на наших теренах, зазначено, що ключовою особливістю римо-католицизму в Україні є презентація його переважно польським етносом, але стійкою тенденцією залишається поступове зростання в Римо-католицькій церкві частки українців. У статті представлені етапи розвитку римо-католицизму в Україні. Починаючи із прийняття християнства в його цілісному вияві (ІХ століття), до польсько-литовського завоювання України міжнародні та міжконфесійні польсько-українські взаємини ще мали деякі ознаки лояльності. Натомість з утворенням Речі Посполитої поширення католицизму в Україні поволі втрачало характер природного процесу і під впливом політичних чинників набувало експансіоністських рис. Для поляків війна за Україну умотивовувалась розширенням життєвого простору. До середини ХVІІ століття раніше шанована в Україні Римо-католицька церква постає у свідомості українців як епіцентр духовного насилля. На етапі після розділів Речі Посполитої наприкінці ХVІІІ століття Римо-католицька церква на українських землях у складі Російської імперії зазнає нещадної метаморфози – з панівної конфесії в Речі Посполитій вона була перетворена на «терпиму» конфесію і, як одержавлена церква, зберігала цей статус до 1918 року. Масовий перехід уніатів (віруючих Української греко-католицької церкви) у римо-католицьку церкву після 1905 року поклав початок новому етапу «розполячення костьолу». За радянської доби, зазначається у статті, три хвилі антикатолицького терору 1930-х – 1940-х років спонукали католиків перейти на нелегальне становище. Тільки наприкінці 1980-х років на рівних правах з іншими конфесіями Римо-католицька церква стає на шлях відродження. Водночас етнічний чинник помітно втрачає значення його домінанти.
АВТЕНТИЧНА РЕЛІГІЙНІСТЬ ПРАВОСЛАВНОГО ВІРУЮЧОГО: ВІД ТРАДИЦІЇ ДО ІДЕОЛОГІЇ
Authors: Кулагіна-Стадніченко Ганна Михайлівна
Published: December 2024

У статті досліджується феномен автентичної релігійності православного віруючого в його взаємозв’язках із релігійною традицією. Показано, що у православ’ї релігійна традиція та релігійна ідеологія можуть співіснувати, але, підпадаючи під значний вплив релігійної ідеології, православне віровчення зазнає маніпуляцій з боку влади, починає грати деструктивну роль у суспільно-політичному житті. Авторка доводить, що в такому разі релігія втрачає функцію миротворця, марґіналізується, отже, вироджується.

The Seattle Clemency Project increases access to justice by connecting people seeking early release from prison and those facing deportation due to old criminal convictions with free legal representation (Seattle Clemency Project, n.d.-b). The organization represents individuals who committed crimes decades ago and have changed their lives for the better. Washington state abolished parole in 1984, leaving the public with a prison system that fails to recognize and reward redemption (Braveman et al., 2022). Washington is also home to many immigrants who qualify for post-conviction relief but lack access to affordable legal representation (McQueeney & Lavelle, 2015). To date, the Seattle Clemency Project has had a substantial impact. The organization has helped 102 people secure freedom from life or long sentences, worked on 22 cases preventing deportation and permanent family separation, matched 275 clients with pro bono attorneys, and generated an estimated $11 million dollars in free legal services (Seattle Clemency Project, n.d.-a).
The First Seven Eruptions of the Hekla Volcano: Some Observations on the Formation of Annual Entries in the Icelandic Annals
Authors:   Institute of World History of the Russian Academy of Sciences, Jackson Tatjana N.
Published: December 2024

This paper continues a series of my works dedicated to the Icelandic annals. It again pro-vides a description of all annalistic collections, written considering the latest scholarly liter-ature on the annals. All medieval Icelandic annals were created at the end of the 13th through the 16th centuries. Information for the preceding time most likely goes back to a single proto-text and was included into the text of the surviving annals retrospectively. As a result, much in the data of the annals for the period before the 13th century matches verba-tim. Partly the overlap in different annals can be explained by the mutual influence of these texts, since they were written and circulated in a certain environment, namely, they were associated with monasteries and bishoprics. The description of events after 1280 has more discrepancies. This might be a consequence of the authors’ independent use of additional sources, oral ones in particular, since the chronological gap between the event and the rec-ord was sometimes no more than one or two generations, and sometimes the annalist himself was a contemporary of the events described. All this is demonstrated in the paper based on the analysis of those entries in the annals that contain information on the seven eruptions of Hekla, the most famous Icelandic volcano.
“I wrote 253 days this year and didn’t write for 100 days…” Prerequisites for the formation of the “character of a scholar” in the childhood diaries of Nikolay Berezhkov
Authors:   Lobachevsky State University of Nizhni Novgorod, Skudnyakova Darya S.
Published: December 2024

This paper examines a set of diary sources from the childhood period of Nikolay Georgievich Berezhkov, Soviet historian, specialist in the history of Old Rus and the Grand Duchy of Lith-uania. In his Chronology of the Rus Chronicles, dates from the earliest Rus chronicles were verified and systematized. Parallel with this work (and directly resulting from it), many is-sues of controversial dating were resolved. The set of childhood diaries of Nikolay Berezhkov for 1897–1900 considered in this article represents a rich source of information about the family and educational environment, which undoubtedly influenced the formation of the scholar’s personality. Based on those ego-documents, an attempt is made to analyze his in-clinations and interests, that later manifested themselves in the historian N. G. Berezhkov, when he was writing his careful and conscientiously verified scholarly works. However, it can be said that the very fact of keeping diaries was a significant prerequisite for Be-rezhkov’s further scholarly work.

The ability to communicate reliably and quickly underwater has been one of the driving forces behind the development of alternative technologies to conventional radio frequency systems. This study explores the performance of Light Fidelity (Li-Fi), a high-speed optical wireless communication technology, in diverse aquatic environments like fresh water, salt water, and turbid water. It evaluates key parameters like signal attenuation, data rate, bit error rate, and transmission range. Results show that Li-Fi offers significant advantages in bandwidth and data rate over traditional methods, but its efficiency is highly dependent on environmental conditions. The study recommends optimizing Li-Fi systems for reliable underwater communication, paving the way for enhanced underwater networking and data transmission applications.
