Authors:   Oles Honchar Dnipro National University, Makedon Viacheslav
Published: October 2024

The article investigated the effectiveness of marketing tools in supporting people with special needs at the international level. Special attention was paid to the use of social media, advertising and PR campaigns as the main tools contributing to the social integration of vulnerable population groups. Social media platforms, including Facebook, Instagram, and Twitter, have proven highly effective due to their accessibility and ability to spread information quickly. It was appreciated that such platforms not only disseminate information, but also provide an opportunity to interact with the audience, engaging communities in active participation. It was concluded that advertising, especially visual, has a significant potential to influence people’s emotions and consciousness, contributing to the destruction of stereotypes and the formation of a tolerant attitude towards people with special needs. However, the effectiveness of advertising campaigns depends on the quality of execution and the authenticity of the submitted content. In this context, recommendations were developed for the creation of emotionally resonant content, which should raise issues of support and solidarity, and not cause pity or feelings of superiority. Examples of successful use of PR campaigns, which allow organizations to create long-term relations with the media and the public, which contribute to a sustainable increase in the level of awareness of the problems of people with special needs, were also considered. It has been estimated that a combination of social media, advertising and PR campaigns provides the best result in achieving social goals. As a result, strategic recommendations were developed to increase the effectiveness of marketing tools in supporting people with special needs. These include involving the target audience in the development of campaigns, ensuring the availability of content, using a multi-channel approach and integrating the latest technologies. Using these recommendations will help build a more inclusive and tolerant society. For the first time, key marketing strategies that are successfully implemented globally to support this vulnerable population have been systematized and evaluated.
THE FUTURE OF UKRAINIAN AIR TRANSPORT: TRENDS AND PROSPECTS
Authors:   University of Customs and Finance, Puhin Oleksandr
Published: October 2024

The article substantiates quantitative changes in passenger flows by different types of transport over the past 40 years. The article analyses the passenger flows of Ukrainian airlines, compares the share of different types of transport in the total volume of passenger traffic during the period of Ukraine’s independence, and draws relevant conclusions about trends in the development of air transport in Ukraine. It is shown that Ukrainians with high incomes remain the main category of passengers on domestic routes. Future growth in demand will depend on the country’s economic growth, airline tariff policy, flight frequency, and convenience of connections. The significant growth in international passenger traffic is partly due to trends that began in 1990. After Ukraine’s independence, imports of goods increased significantly, and demand for international travel increased significantly. It is also worth noting that Ukraine’s transport infrastructure allows you to reach any part of the country using land transport, which is much cheaper than air travel. Therefore, it is not surprising that most domestic airlines are focused on international transport. The significant potential for the development of international flights in Ukraine is due to the country’s geographical location, which facilitates high transit passenger traffic. When analysing the performance of European airports, it is worth noting that Ukraine became the leader in terms of passenger traffic growth in 2019. In six months, Ukraine’s airports handled 10.7 million passengers, up 20 % year-on-year. Ukraine ranked second after Poland in terms of passenger traffic. In addition, Ukraine has seen a steady increase in passenger traffic due to the emergence of new airlines and the expansion of international routes. Low-cost airlines, such as Ryanair and Wizz Air, have begun to operate in the Ukrainian market, which has led to lower airfares and increased accessibility of air travel for the general population. At the same time, Ukrainian airlines, such as UIA (Ukraine International Airlines), continue to expand their routes, which is contributing to further growth in passenger traffic. Looking at domestic traffic, although the share of air travel remains relatively small compared to other modes of transport, such as rail and road, there is a gradual increase in interest in air travel due to improved services and infrastructure at airports. The development of regional airports is also contributing to an increase in the number of passengers using air transport within the country. Overall, the prospects for the development of air transport in Ukraine look optimistic. The main factors that will contribute to further growth of passenger traffic are economic stability, development of the tourism industry, improvement of service quality and investment in infrastructure.

The purpose of the article is to research stress testing for the implementation of the mechanism for ensuring the financial component of the economic security of the enterprise, taking into account the criterion of financial resource saving. The relevance of this research lies in the application of forecasting within the framework of stress testing, the determination of the possible options for the development of the events in the relation to external and internal factors of the enterprise and its implementation in the mechanism of financial security. Research methods are applied in the research: system analysis and synthesis, systematization, comparison, method of statistical data processing. In the conditions of uncertainty of the external and internal conditions of the company’s activity, the role of forecasting, on which stress testing is based, is growing especially acutely. The article examines the essence of the concept of stress testing and considers the views of various authors regarding its application in order to ensure the economic activity of the enterprises. The use of the stress testing is proposed in order to improve the mechanism of the ensuring the financial component of the economic security of the enterprise, taking into account the criterion of financial resource saving. It was determined that the stress testing process is associated with risks, and since deposit risk is the main factor for financial resource conservation, the influence of external and internal factors on deposit risks was considered. The external factors include: the reliability of a commercial bank, changes in the legal framework, the political and economic situation in the country, exchange rate fluctuations, inflation, and the internal factors include: an unsuccessful choice of a bank for the investing funds and the depositor’s immediate need for the cash. Tools for the ensuring financial security are proposed, taking into account the criterion of the financial resource saving. As a part of stress testing, a forecast of the US dollar exchange rate and the consumer price index was made. The practical value of the article lies in the fact that, based on the completed forecast, measures are proposed to ensure the financial component of economic security based on financial resource saving.

Published: October 2024

Питання щодо забезпечення населення якісною питною водою залишається актуальним сьогодні для більшості міст України, в т.ч. Луцька. Водопостачання м. Луцьк здійснюється із підземних джерел 3-х водозаборів: Дубнівського, Гнідавського та Омелянівського Основним джерелом водопостачання міста Луцька є Дубнівська насосна станція водопідготовки КП «Луцькводоканал», що забезпечує очищення, зберігання і подачу води для населення міста. Якість питної води централізованих систем водопостачання залежить від якості вихідної води, ефективності технологій її підготовки, методів кондиціювання артезіанської води, а також стану водопровідних мереж і регулярності їх експлуатації. Проаналізовано показники якості питної води, взятої з різних місць відбору центральної частини міста та перевірено їх на відповідність вимогам санітарних норм України. Для цього використано органолептичні та лабораторні методи дослідження. Виявлено, що питна вода, яка надходить з Дубнівського водогону до населення міста розгалуженою водопровідною мережею, залишається практично незмінною і рекомендована до споживання. Найнижчі фізико-хімічні показники були зафіксовані у пробі води відібраної з автомата Ecosoft, яка вважається, занадто маломінералізованою. Споживання такої води може призвести до порушення фізіологічних функцій організму людини. Показано, що використання фільтрів або відстоювання води зменшують уміст кальцію та загальну твердість води. Визначено, що проба води з кулера мала найнижчі значення твердості води, мінералізації та вмісту магнію, а кальцій в ній був відсутній зовсім. Розглянуто вплив споживання питної води з різним умістом хімічних елементів на здоров’я населення та запропоновано рекомендації щодо споживання корисної питної води.

Біорізноманіття є одним із найцінніших природних ресурсів, які потрібно оберігати, оскільки забезпечує стійкість екосистем та здоров'я нашої планети. Звірівське лісництво відіграє ключову роль у збереженні цього біорізноманіття через свою діяльність у лісовому господарстві та охороні природних ресурсів. Метою роботи є проведення детальної екологічної характеристики біорізноманіття на території Звірівського лісництва. До основних чинників у галузі контролю за використанням природних ресурсів та збереження біорізноманіття, належить характеристика існуючого біорізноманіття та вплив антропогенних та інших факторів на біорізноманіття. Звірівське лісництво розташоване у Волинській області на території Луцького району. Адміністративно-організаційна структура підприємства включає лісництва "Звірівське" і "Мощаницьке", з площею 3504,2 та 4729,4 га. Для дослідження проводилась інвентаризація біорізноманіття, процес складання списку біологічних об'єктів даної території. Це передбачає детальний опис географічних і екологічних умов місцезнаходження, попередню ідентифікацію біологічних об'єктів, їх збір, каталогізацію, з подальшим контрольним оглядом через певний час, а також аналіз інформації про таксономічний статус та екологічні характеристики цих об'єктів. Дослідження, були проводені в період з 2023 по 2024 рр. Нами вперше було досліджено та систематизовано біорізноманіття Звірівського лісництва. А також в роботі була використана Червона книга України (Рослинний світ, Тваринний світ) та системи категорій і критеріїв Червоного списку Міжнародного союзу охорони природи (МСОП) для оцінки стану різноманітних видів. Цей підхід дозволив об'єктивно класифікувати види залежно від рівня їхнього ризику зникнення. Результати дослідження вказують на те, що Звірівське лісництво ефективно та раціонально використовує лісові ресурси, сприяючи відновленню лісового покриву та підтримці біорізноманіття. Це досягається завдяки управлінню, спрямованому на збереження природних екосистем та їхню екологічну стійкість. Загальна еколого-географічна характеристика Звірівського лісництва свідчить, що господарство відіграє важливу роль у збереженні біорізноманіття. Проте існує потенційний ризик порушення екосистеми та втрати біорізноманіття через неконтрольовану діяльність у лісах.

A Possible Aether Explanation for Two Light Phenomena: Varying Speed with Medium and Cosmological Redshift
Authors:   Amelung St, Frederick, Maryland, HV Gallucci Raymond
Published: October 2024

The speed of light (3.00 x 105 km/s in a vacuum) lies beyond human comprehension, especially if one is to postulate that it can be achieved ballistically by a particle, even a “massless” one such as a photon. If such speeds are attainable, which experimentation and astronomical observation apparently have “proven,” then it is slightly less of a leap of faith to imagine such speeds to result from wave phenomena, suggesting that a propagating medium for light must exist (an “aether”) despite such allegedly having been disproven pre-Einstein. With this possibility in mind, two light phenomena are examined from the perspective of an aether as light’s medium of transmission.

Published: October 2024

A field experiment was carried out at the farmers' field in the Kaliganj upazila for two consecutive years (2021-22, 2022-23). The experiment carried out in a multi-location testing site in the Jhenaidah district, under the Jashore region. The objective of the experiment was to enhance cropping intensity and productivity by incorporating T. Aus into the existing cropping pattern. The current cropping sequence consisted of T. Aman-Mustard-Mungbean, while the suggested cropping sequence included T. Aman- Mustard-Mungbean-T. Aus. The research findings showed that the rice equivalent yield (REY) in the suggested cropping pattern was 21 t ha-1, representing a 31.25% increased over the yield of existing pattern (16 t ha-1). The greater gross return (Tk. ha-1), gross margin (Tk. ha-1), and slightly higher marginal benefit cost ratio obtained from this four-crop-based cropping pattern suggest that the proposed pattern could be recommended for higher productivity and economic benefit in other parts of the Jashore region.

Spades and Gravers: Clare Leighton, Victor Gollancz and the Radical Countryside
Authors: Bluemel Kristin
Published: October 2024

Socialist artist, wood engraver, and writer Clare Leighton transformed the interwar wood engraving revival from a niche movement within fine book publishing into an everyday art for the people when in 1935 she brought out with leftist publisher Victor Gollancz her authored and illustrated Four Hedges: A Gardener's Chronicle. Read alongside Country Matters (1937), a second illustrated countryside book that Gollancz commissioned from Leighton, Four Hedges becomes a key 1930s text because it realigns modernist values associated with the wood engraved productions of small presses with the more democratic values of mass-reproduced trade books. Combining feminist biography, close reading, and modernist and middlebrow book history, this article argues that the wood engraved books that Gollancz commissioned from Leighton contribute to rather than resist or exist outside of the radical 1930s once they are located within Leighton's rural arts practice and Gollancz's publishing ventures, including his publication of George Orwell's legendary urban documentary, The Road to Wigan Pier (1937).

A multi-objective optimization strategy integrating a deep learning surrogate model is explored to enhance the flow and heat transfer performance of a lantern-shaped pin fin channel. Three geometric variables representing diverse crosssectional pinfin shapes are selected to fit the shape profile. The pix2pix deep learning framework has been improved to reinforce precision and reduce overfitting risks by integrating residual network units and stochastic gradient Hamiltonian Monte Carlo. The data processing has been thoroughly evaluated, and parameters including convolution kernel count and down-sampling frequency were optimized before optimization. With the maximum Nusselt number and minimum friction factor of the pin-fin channel as the objective optimization functions, eight points along the Pareto front were meticulously selected to dissect the lantern-shaped pin-fin's profile variations. The results indicate prediction errors for the endwall are 6.06%, 1.36% for the pin-fin surfaces, and 1.38% for the total channel. As aerodynamic losses diminish, the pin fin's central cylinder gradually transitions into a spherical form. Pareto 4 emerges as a recommended compromise solution, reflecting a 5.24% decrement and an 11.54% marginal increment relative to the maximum thermal performance and the minimum loss scenario, respectively.

Published: October 2024

A new vacuum experimental facility is established and the vibrational characteristics of a rotating integrally bladed disk are studied without the interference of aerodynamic forces. Swept-sine excitation is implemented by a piezoelectric system. The response is measured using both strain gauges and blade tip timing. 10 modes in the first flexural bending (1F) mode family and 11 modes in the first torsional (1T) mode family are recognized by combining the two types of measurements. The deviations of the resonance frequencies estimated by BTT and SG are less than 0.08% for the 1F modes and 0.1% for the 1T modes.

To improve damper’s performance in the vicinity of dual-rotor systems’ multiple critical speeds, an optimization design method is proposed in this paper. Firstly, an active elastic support/dry friction damper (ESDFD) is investigated for damping vibration of the dual-rotor system. A dynamic model of the dual-rotor system with ESDFDs is built by the finite element method. Then, the effect of the ESDFD on the dual-rotor dynamic characteristics is analysed. Importantly, through numerical study, relationships between the damping performance of the ESDFD and the rotor’s modes are shown. And the squirrel cage support stiffness is selected as the optimization variable. Based on this, the optimization objective function is constructed by considering the critical speed constraint, sensitivity of unbalance, and controllability of the damper. Finally, the optimization parameters are obtained by the improved particle swarm optimization algorithm. And the simulation results show that the dual-rotor is less sensitive to the unbalance and the damper’s controllability significantly improves. Keywords: elastic support/dry friction damper; vibration control; dual-rotor system; optimization design; improved particle swarm algorithm

Ehrlichiosis is a potentially life-threatening disease caused by infection with the obligatory intracellular bacteria Ehrlichia species. Ehrlichia japonica infection of mice provides an animal model of ehrlichiosis as it recapitulates full-spectrum and lethal ehrlichiosis in humans. The E. japonica transposon mutant of EHF0962, which encodes a previously uncharacterized hypothetical protein, is attenuated in both infection and virulence in mice. EHF0962 was hence named here as resistance-inducing protein of Ehrlichia (RipE). Using this ΔripE mutant, we studied how RipE protein contributes to Ehrlichia pathogenesis. Ehrlichia species have an intracellular developmental cycle and a brief extracellular stage to initiate a new cycle of infection. Majority of RipE proteins were expressed on the surface of the smaller infectious dense-core stage of bacteria. Extracellular ΔripE E. japonica contained significantly less adenosine triphosphate (ATP) and lost infectivity more rapidly in culture compared with wild-type (WT) E. japonica. Genetic complementation in the ΔripE mutant or overexpression of ripE in WT E. japonica significantly increased bacterial ATP levels, and RipE-overexpressing E. japonica was more virulent in mice than WT E. japonica. RipE is conserved among Ehrlichia species. Immunization of mice with recombinant RipE induced an in vitro infection-neutralizing antibody, significantly prolonged survival time after a lethal dose of E. japonica challenge, and cross-protected mice from infection by Ehrlichia chaffeensis, the agent of human monocytic ehrlichiosis. Our findings shed light on the extracellular stage of Ehrlichia, highlighting the importance of RipE and ATP levels in Ehrlichia for extracellular resistance and the next cycle of infection. Thus, RipE is a critical Ehrlichia protein for infection as such can be a potential vaccine target for ehrlichiosis.

Introduction

Staphylococcus aureus is a highly resistant pathogen. It has multiple virulence factors, which makes it one of the most pathogenic bacteria for humankind. The vast increase in antibiotic resistance in these bacteria is a warning of existing healthcare policies. Most of the available antibiotics are ineffective due to resistance; this situation requires the development of drugs that target specific proteins and are not susceptible to resistance.

Methods

In this study, we identified a compound that acts as an antagonist of ClfA and ClfB by inhibiting their binding to host cells.

Results

The shortlisted compound’s binding activity was tested by docking and molecular dynamics during its interaction with proteins. The identified compound has excellent binding energy with both ClfA (-10.11 kcal/mol) and ClfB (-11.11 kcal/mol).

Discussion

The molecular dynamics of the protein and compound were stable and promising for further in vitro and in vivo tests. The performance of our compound was tested and compared with that of the control molecule allantodapsone, which was reported in a previous study as a pan inhibitor of the clumping factor. An ADMET study of our selected compound revealed its reliable drug likeliness. This compound is an ideal candidate for in vitro studies.

Introduction

Social-ecological systems (SES) recognize the intricate relationship between human activities and the environment and advocate for comprehensive approaches to address complex environmental issues. This study investigates the factors influencing whale watching, particularly the gray whale (Eschrichtius robustus) in northern Mexico, after significant recovery following overexploitation. Despite reaching a peak in 2015, the eastern North Pacific gray whales experienced unusual mortality events (UME), the most recent from 2019 to 2023, leading to a population decline and historically low calf production in 2022. This decline is evident in the reduced presence of whales and calves in winter breeding lagoons. Concurrently, whale watching has become a significant tourist attraction in these areas.

Methods

Our objective was to develop a mental model of the SES of gray whale watching, integrating ecological and socioeconomic data to identify key variables and interactions that support system resilience. From an ecological perspective, we analyzed the long-term temporal trends of eight years of gray whale counts in the southernmost breeding and nursing lagoons within the Bahía Magdalena–Bahía Almejas Complex, Mexico. Additionally, we incorporated the current discussion in the literature about the potential impact of global climate change on gray whale populations. In the socioeconomic subsystem, we used participatory methods, including interviews, surveys, and workshops with government officials, tourism operators, and visitors. We also added on-site assessments of compliance with welfare regulations to understand tourism dynamics.

Results

Our findings identified as main external stressors the changes in ice levels in feeding areas and sea warming in breeding areas, and as internal stressors the compliance with official regulations and the number of vessels observing whales at the same time. The key socioeconomic factor of the system was tourist satisfaction, influenced by factors such as the quality of the information provided by operators.

Discussion

Ultimately, our mental model provides a framework for further exploration of relevant interactions and trajectories, offering insights for developing effective management strategies.
Influences of inflow rates on the breach characteristics of landslide dams

Published: October 2024

Introduction

Dams formed by landslides may produce disastrous floods after dam outbursts. However, understanding of the influence of the inflow rate on the breaching characteristics of landslide dams is still at an early stage; in particular, the relationship between breaching width and depth are still unclear.

Methods

In this paper, we present the results of a series of laboratory tests that assessed seven inflow rates (1, 1.5, 2, 2.5, 3, 3.5, and 4 L/s).

Results and discussion

The results show that breaching characteristics for different inflow rates are similar and that there are three breach stages for different inflow rates. The peak discharge gradually increases as the inflow rate increases. With increasing inflow rate, the breach depth and width both increase. The ratio of breach width to breach depth increases from less than 1 to 1 progressively with increasing inflow rate. The breaching width and depth can be expressed by the function W=ζ1+e−kD−D0. The shape parameter k has an exponential relationship with the inflow rate.

This research investigated the details and effects of a short online Professional Learning Program designed to develop teacher education students’ knowledge about how to promote self-regulated learning (SRL) in the classroom. The Program was based on a new framework for how teachers can promote SRL, the SRL Teacher Promotion Framework (SRL-TPF), which focused on the promotion of SRL strategies, students’ knowledge about learning, and students’ metacognition. It consisted of seven modules describing the different SRL promotion types and SRL capabilities and ways to promote them through teacher talk and action. Modules included written information and video examples taken from observations of real classrooms, which were used to illustrate the transfer of SRL theory to instructional practice. Each module concluded with several assessment items. During the Program the participants, 91 teacher education students, were asked to use a simplified scoring system based on the SRL-TPF to code lesson transcripts taken from classroom observations. The results showed that by the end of the program over 85% of the participants were able to provide teacher instructions that included explicit SRL promotion and/or promoted students’ SRL knowledge. Our study contributes to research findings on teacher education students’ knowledge of SRL, their promotion of SRL to students, and the contribution of short duration SRL professional development.
