The article examines the potential for the development of professional and amateur
winter sports infrastructure in Kremenets town, Ternopil region. On the basis of
pre-project studies, a project concept for the development of winter sports
infrastructure in Kremenets town was developed. The expediency of expanding the existing
material base of winter sports and supplementing it with new facilities, in particular,
the creation of an educational and recreational center for alpine skiing in the
Volovytsia mountain within the city limits, is substantiated. The following methods were
used during the research: content analysis of scientific, normative, archival materials
and urban planning documentation; field surveys with analysis of residents'
movement trajectories; comparative analysis of the design experience of winter tourism
and sports centers in Ukraine and abroad; monitoring of some of these complexes visitors
behavior; analysis and evaluation of the natural and urban planning potential of the
city territory; analysis of technical, ecological and socio-economic aspects related to
the design of a new center of winter sports in Kremenets. The principle approaches to
the formation of the concept of winter sports infrastructure development in the
Kremenets town, Ternopil region are defined: the application of a systemic approach with
the modernization of the existing resource base and the combination of new facilities
with the existing ones with the help of convenient transport and pedestrian connections;
ensuring a sufficient number of beds for reception and accommodation of athletes in the
city; taking into account the visual relationships between the planned centers of winter
sports and the landscape and architectural dominants of the city; taking into account
the value of natural landscapes when choosing the location of the planned complexes of

The article highlights and analyzes the modern and foreign experience of designing
and building temples of various religions and denominations with spaces for public
activities, which is relevant for the revival of objects on the boundaries of functions
for the near and future perspective. The need to highlight the results of modern
domestic and foreign experience in the design and construction of temples of various
religions and denominations with spaces for public activities, caused by the destruction
of the network of public buildings and structures, which was formed by 3000 varieties
and types, requires an incredible amount of time and money. However, there is an
alternative, which consists not only in the construction of new temples with spaces for
public activities, but also in cooperation between buildings that are similar in
function and purpose. Such cooperation can cover one, two, three or more objects, which
will ensure more efficient use of resources and increase the functionality of the space
as a whole. The research emphasizes that the design of such objects requires adaptation
to regional traditions and socio-cultural conditions. The article mentions outstanding
Ukrainian architects who implemented innovative projects of temples in the USA, Canada,
Brazil and other countries, including M.-D. Nimtsiv and R. Zhuk. The authors of the
article also analyze examples of modern churches, which, thanks to their complex
functions, serve not only as religious centers, but also as cultural and educational
spaces. According to the results of research conducted by the department of
architectural environment design, it was established that public spaces near temples can
be classified according to several criteria: the form of plans, markings, volume-spatial
solutions, as well as the number of functional and operational elements. As a result of
these studies, a series of educational and research projects was developed, which are
aimed at meeting the real needs of customers. and, in particular, the town hall of the
territorial community "Zymna Voda" near Lviv, which demonstrates a practical
approach to the integration of religious and social functions in modern
architecture.

Published: December 2024

The article is devoted to a detailed review of the High Castle - one of the key
historical monuments of the city of Lviv, which carries centuries-old history, cultural
and historical traditions. Located on one of the highest hills of Lviv, the castle
witnessed numerous historical events that took place on the territory of Ukraine and
Europe. Its walls preserved the history of greatness and fall, cultural flourishing and
war destruction. Despite the fact that time and historical events have mercilessly
affected the preservation of the castle, it remains an important part of the historical
heritage and cultural landscape of Lviv. From descriptions stored in illustrations and
inventories, from various archival references, from plans and old drawings on engravings
and oil paintings - it is possible to reproduce an incomplete picture of what our High
Castle looked like. However, the study of the history of the fortifications of the High
Castle is largely found in the works of historians such as D. Zubrytskyi (Zubrytskyi,
2006), M. Hrushevskyi (Hrushevskyi, 1897) and S. Tersky (Tersky, 2010). In his
monograph, O. Cholovskyi (Cholovskyi, 1910) provides a brief outline of the history of
research into the High Castle, information about the layout and features of the castle
buildings. In Ukrainian architectural science, there is no systematized, comprehensive
and unified historical and architectural information about the architectural development
of the High Castle, which belongs to the historical and architectural monument of
national importance, is an object of the protected zone of the city center of Lviv. The
main attention in the article is devoted to a comprehensive description of all of the
premises of the High Castle, namely information on the functional purpose of the
premises with a detailed description of their historical purpose, architectural
features, unique artifacts and exhibits. Connections between architectural elements and
historical periods of the castle's development have been established.

Examining current regional intensity of trade in Africa: How strong are the trade linkages and implications for intra-Africa trade in the African Continental Free Trade Area
Authors:   Rhodes University, Department of Economics and Economic History, South Africa, Effie Mutambara Tsitsi
Published: December 2024

The African Continental Free Trade Area (AfCFTA) is a continent-wide free trade area which is expected to pave way for a continental customs union. This article assessed the current state and extent of intra-Africa trade in 2001-2018. The results give insights into the foundation which the current regional economic communities in Africa have put in place regarding intra- and inter-trade linkages. This is a foundation which the AfCFTA would utilise to achieve trade integration in a continent-wide economic integration arrangement that seeks to improve intra-Africa trade. Five regional groups were considered, namely Arab Maghreb Union, East African Community, the Economic Community of West African States, Economic Community of Central Africa States, and the Southern African Development Community. Intra-regional trade intensity index results show that trade within individual regional groups, and within Africa, is oriented towards respective member countries, although there is no evidence of increased inward orientation over time. Inter-regional trade intensity index results show that most regional groups trade intensively with each other, albeit at different levels. With increased market access in the AfCFTA through lower trade resistances between regional groups, inter-regional trade is expected to increase as per the volume of trade criteria in the natural trading partners hypothesis.

Published: December 2024

Erectile dysfunction (ED), an unusual sexual condition in which the person fails to attain or sustain an erectile penis, severely impacts personal relationships, confidence, and efficiency. To date, low-intensity extracorporeal shock wave therapy (Li-ESWT) is an option to manage ED; however, it is associated with adverse events such as bruising, redness, and pain. Hence, in this study, we applied platelet-rich plasma (PRP), a blood-derived biomaterial containing cargo of growth factors, to enhance the therapeutic efficacy of Li-ESWT on ED. We assessed the synergistic effect of PRP+Li-ESWT, in which Li-ESWT was extracorporeally applied simultaneously with PRP. They were evaluated clinically at 22 ± 2, 50 ± 2 and 78 ± 2 days. Statistical analysis was performed using a non-parametric test, Friedman repeated measures as an alternative non-parametric test of ANOVA test. The international index of erectile function (IIEF-5) and erection hardness score (EHS) were recorded. IIEF-5 score in the pre-treated group was 8.36 ± 1.44. After 22 ± 2 days of synergistic PRP+Li-ESWT treatment, the score was 14.45 ± 2.12 (p < 0.028). This score further increased to 15.45 ± 1.93 (p < 0.008) and 16.18 ± 1.48 (p < 0.001) after 50 ± 2 days and 78 ± 2 days of treatment, respectively. The mean pre-treated EHS was 1.64 ± 0.20 (p < 0.002), which increased to 2.81 ± 0.26 (p < 0.002), 3.09 ± 0.25 (p < 0.0002) and 3.18 ± 0.12 (p < 0.000) on day 22 ± 2, 50 ± 2 and 78 ± 2 days, respectively. Conclusively, our study demonstrated potent synergistic therapy of PRP+Li-ESWT in ED treatment by improving IIEF-5 and EHS scores. However, extensive mechanism-based clinical studies are needed to reach a consensus.

Features of building a successful logistics business in the USA
Authors: Mardonova E.
Published: December 2024

The very intensive development of e-commerce and changing consumer behavior in the United States have provoked an unprecedented increase in freight traffic. This trend is increasing every year. Existing logistics models sometimes demonstrate the inability to effectively cope with the increased workload, which necessitates a rethink of traditional approaches to business organization in the area under consideration.

There is no common position in the scientific community regarding optimal scaling strategies for logistics companies in the context of digital transformations. A number of researchers advocate the priority of technological modernization, while others focus on strengthening regional partner networks. The indicated contradiction is aggravated by the lack of knowledge of synergetic effects when integrating various options for action.

The purpose of the study is to identify key success factors in building and scaling a logistics business in the United States through the prism of technological transformation of the industry and changes in market conditions.

It is noted that companies integrating elements of classical logistics with digital platform solutions demonstrate an increase in the profitability of operations. At the same time, the critical success factor is not the volume of investments in technological modernization, but the ability to create effective synergy between various parts of the entrepreneurial model. The author’s view on the options for the development and scaling of logistics entrepreneurship in the United States is proposed.

The article is of value to the heads of logistics companies, investors considering the possibility of entering this sector in the United States, as well as researchers dealing with the digital transformation of the analyzed industry.
Development of the Northern Sea Route as a space for entrepreneurship and trade
Authors: Novozhilov A. M.
Published: December 2024

Since ancient times, travelers, discoverers, entrepreneurs and traders have sought to find the most rational route from one area of the globe to another. Reducing distances in space means reducing commercial transactions in time, accelerating trade turnover, saving money, and increasing profits. Such circumstances have long stimulated economic participants to search for new transport routes for trade communications. They were looking for the shortest and most convenient routes from European countries to the riches of the countries of the East, India and China. Land and water routes through the regions of the North were developed. The development of northern routes began a long time ago. Already from the 6th–9th centuries, the settlement of the Eastern Slavs in northern Europe took place. From the 8th century, the Slavs began to develop the White Sea region. From the 12th century, the areas of the Kholmogory region were mentioned; Kochi Novgorodians and Pomors already walked along the western parts of the Arctic Ocean. Since the 16th century, the British and Dutch have sought to pave the way to the East through the northern seas, and trade, political and cultural ties between Russia and Western countries have been formed. Trading companies emerged; the British and Dutch, through joint–stock companies, attracted broad masses of people and their capital to colonial policy, which for a long time became the key to effective colonial activity. The Russian Empire and the young Soviet state continued to explore the Northern Sea Route.

Comparative analysis of traditional and automated financial management methods
Authors: Frolov E. A.
Published: December 2024

The article examines the problems of using traditional and automated methods of financial management, the relevance of which is due to the rapid digital transformation, which creates the need to rethink the methodological foundations. In science, there is a contradiction between established classical management practices and new capabilities of automated systems, which creates uncertainty when choosing optimal approaches to the organization of financial processes. The purpose of the study is to conduct a comprehensive comparative analysis of the management methods under consideration based on a system of criteria (methodology for processing financial information, time characteristics of accounting processes, structure of information flows, mechanisms for controlling operations, principles of reporting, organization of analytical accounting, decision–making procedures, data integration, system scalability, documentation support). The author’s vision of the advantages, disadvantages and limitations of classical options and automation is formulated. It was possible to conclude that the fundamental differences between the characterized methods are determined not only by technological potential, but also by fundamentally different approaches to the organization of information processes. At the same time, the identified differences do not exclude the possibility of methodological integration, provided that the basic principles of financial management are preserved. The presented materials are of practical value to the heads of financial departments, accounting process methodologists, developers of automated management systems.

Hypertension in pregnant women is one of the public health concerns globally and its management requires a consideration of benefits outweighing the risk of treatment. Patients’ knowledge and practices regards to the disease and medication is crucial in ensuring the reduction in morbidity and mortality rate in the mother and foetus. This study aimed to assess the level of knowledge and practice of hypertension and its management, the medication use and factors associated with a good level of knowledge and practice in pregnant women with hypertension. This study was a cross-sectional, observational study, using a self-administered questionnaire, involving a total of 70 pregnant women who were attending antenatal checkup in Hospital Al-Sultan Abdullah (HASA), UiTM Puncak Alam, Selangor, Malaysia. Majority of the participants had poor knowledge regarding hypertension during pregnancy (55.71%) but adopted good practice (74.29%) on the disease management. Majority of participants showed a good level of knowledge (68.6%) and practice (82.86%) on the medication use during pregnancy. Pharmacists were the major (35.7%) source of information in seeking information on the medication followed by doctors and online resources. Factors such as higher age, higher education, and having more children are linked to a high level of knowledge on medication use. Good practices in medication use are associated with high education, employment, and having one to three children. Factors related to good knowledge of the disease and its management include being over 30 years old and living in an urban area. In contrast, paticipants who is over 30 years old is associated with good practices in disease management. It is evident that most participants exhibited good knowledge and practice regarding medication use during pregnancy, despite significant knowledge gaps related to hypertension. This research may project a refine guideline for a comprehensive and targeted patient education aiming good maternal health outcomes.
Contribuciones de Max Neef et al. a la teoría de las necesidades humanas

Este trabajo tiene como propósito valorar críticamente las contribuciones de Max-Neef et al. a las teorías relacionadas con las necesidades humanas. En primer lugar, se describen quince postulados propuestos por los autores, destacándose como principales aportes la definición de necesidades, satisfactores y bienes, así como sus ritmos de cambio. Además, se califica su matriz de necesidades y satisfactores como atractiva y sugerente, aunque insuficientemente elaborada; en particular, la distinción entre satisfactores y bienes resulta funcional únicamente cuando el satisfactor es una actividad humana. Por otra parte, se señala que, cuando los bienes se convierten en fines en sí mismos, la supuesta satisfacción de necesidades obstaculiza las posibilidades de vivirlas plenamente, lo que da lugar a una sociedad alienada. Asimismo, se describe su tipología de satisfactores y se realiza una comparación entre su esquema de necesidades y otros ocho modelos teóricos.

Climate change and overuse of natural resources pose serious threats to Europe and the rest of the world. Rapidly growing urban environments, coupled with changes in lifestyle and consumption patterns, require well-designed measures to ensure sustainability in development. To address these challenges, the European Union has adopted the European Green Deal strategy, which aims to turn the EU into a modern, resource-efficient, and competitive economy. The main goals of this strategy are to achieve net-zero greenhouse gas emissions by 2050, decouple economic growth from resource consumption, as well as to ensure that no individual or community is overlooked. In this review we aimed to demonstrate that Tagetes spp., a popular and widely cultivated ornamental plant commonly known as marigold, has numerous capacities which can contribute to achieving the goals of the European Green Deal. In particular, we show that marigold can be used 1) in public health system either as a traditional medicine or in controlling environment against disease-transmitting pests; 2) as a component of a healthy food chain; 3) as a source of natural compounds in transforming pharmaceutical and chemical industries towards principles of circular economy; 4) in natural methods of soil remediation, especially under conditions of rapid urbanization; 5) in sustainable agriculture with reduced use of resources. Overall, Tagetes plants can be seen as a natural tool to achieve the goals of the European Green Deal strategy in improving public health and preserving the environment.

It is determined that the number of children with special educational needs is increasing in preschool education institutions. It has been studied that today preschool education institutions are attended by children with the following disorders: autism, delayed speech development. It is determined that for children with special educational needs, the creation of an inclusive group and the functioning of a resource room are provided. The educational process of such children is carried out on the basis of an individual development program in accordance with the conclusion of a comprehensive psychological and pedagogical assessment of their development. It was clarified that the development of an individual program for the development of children with special educational needs is carried out by members of the psychological and pedagogical support team. It has been established that inclusive groups can be attended by one to three children, depending on the levels of support, which are from the first to the fifth. Advice to parents on the necessity of applying to an inclusive resource center is outlined. It is substantiated that children with special needs should receive from two to eight psychological, pedagogical and correctional and developmental sessions per week, depending on the level of support, their age, the degree of complexity of their disorders and taking into account their individual characteristics. It has been established that the duration of classes depends on the age of the child and the type of activity in the educational areas.

The European Union (EU) has been the global leader in sustainable development strategy and climate change mitigation for decades. Key strategic documents, which indicate dedicated environmentally friendly policies of the Union, include, e.g., Europe 2020 Strategy, the Strategy for Circular Economy, the European Green Deal (EGD), and Fit for 55 package. In terms of Europe 2020 strategy on smart, sustainable and inclusive growth, the EU reached over 20% reduction of greenhouse gas (GHG) emission (from 2010 to 2020). And in terms of EGD, the most ambitious goal was set to make Europe the first climate-neutral continent with zero net GHG emission by 2050. Open Russian aggression against Ukraine in Feb 2022 forced Europe to be ready for new challenges, including overcoming dependence on Russian energy resources. Answering these challenges, the EU adopted REPowerEU strategy to eliminate its dependence on Russian fossil fuels till 2030. The Union imposes economic sanctions on the Russian regime and provides powerful financial support to Ukraine. Keeping in mind a huge military machine of Russia and terrorist way of thinking of its leader it seems we still need much more international efforts to turn Europe back to a sustainable track of development.

In recent years the Polish food industry has faced a sharp increase in production and marketing costs, disruptions in the supply chains of raw materials, consumables and packaging, as well as the loss of traditional sales markets due to the war in Ukraine. The study of the peculiarities of the Polish confectionery market made it possible to assess the main indicators of the Polish market of confectionery goods of all categories, as well as its volume and trends. It was concluded that during 2022 there was a 12% increase in the volume of production of confectionery goods of all categories. At the same time the manufacture of Polish flour confectionery products increased by 19.3%. The growth rates of production of cocoa–rich and sugar sweets were 3.8% and 6.8%, respectively. It is necessary to mention that during 2022 a record number of products were exported from Poland, exceeding the similar figures of the previous year by 13.8%.
Meanwhile, despite the presence of developed domestic production of confectionery goods in Poland, the volume of imported supplies traditionally remains high and increased by 7.8% in 2022. At the same time, the level of competition in the Polish domestic market for flour, cocoa–rich/chocolate and sugar confectionery products is estimated as high.

The full-scale Russian invasion of Ukraine in February 2022 and the ongoing Russian-Ukrainian war have a dramatic impact on every aspect of life in Ukraine and beyond. Russia continues to commit innumerable war crimes. To make the perpetrator responsible for all its crimes requires painstaking recording, which by itself demands careful counting, estimations and forecasts highlighted in relevant internationally renowned publications. So far, only a handful of scientific reports have been published, mostly in Ukrainian language, with limited availability to the international community. A substantial category of war crimes is ecocide, a purposeful devastation of ecosystems with a potential to trigger environmental disasters. Up to now almost 5.3 thousand facts of the damage to the environment as a result of Russian aggression have been documented. Over 100 million tons of pollutants and 110 tons of poisonous substances were released into the air due to fires at industrial facilities and forests. About 860 thousand m2 of land was contaminated and almost 20 million m2 was clogged. Tens of thousands of tons of foreign objects were dumped into the land water bodies. Seawater also badly suffered. One of the most atrocious single-event damage to the environment was the destruction of the dam of the Kakhovka Reservoir on Dnipro River in June 2023. As a result, 61 settlements were flooded, 465 tons of oil most likely got into the Dnipro River, 333 biotic species were at risk of death.
The total damage caused to the environment in Ukraine by Russian invaders is more than EUR 57 billion. Here we present a report on the environmental crimes of Russian invaders to support the international efforts to stop the aggressor and to lay ground to holding the Russian regime responsible and getting full compensations for its crimes.
