Topicality. Currently, the demand for transport by inland waterways is constantly growing, especially in economically developed countries. In order to maintain the national economy and create a more efficient and sustainable logistics system in Ukraine, transportation by inland waterways must be developed, because inland waterway transport has a number of advantages over other modes of transport, which creates the preconditions for changing logistics routes. To reduce transport costs, improve infrastructure and logistics in the face of uncertainty, the relationship between the stakeholders of rail and road transport with representatives of water transport is important. Reorientation of transportation from road transport to inland waterway transport, intensification of international trade and attraction of new freight flows to inland waterway transport will contribute to the overall growth of the country's economy and is possible subject to liberalization of transportation.Aim and tasks. The purpose of the article is to substantiate the economic and environmental feasibility of transporting goods by inland waterway transport in the context of the global trend of the need to preserve the environment and rational use of resources.Research results. The port infrastructure of Ukrainian rivers also does not meet modern requirements and is actually in decline. Most of the ports are located in the central areas of cities, causing the destruction of city roads by trucks that are sent for loading / unloading at these ports. In the context of the global trend of the need to preserve the environment for most countries of the world, inland waterway transport is the cheapest and most environmentally friendly mode of transport, suitable for transporting significant volumes of products, mainly raw materials. In Ukraine, the volume of cargo transported by river transport has significantly decreased over the past decade. Of the available volumes of freight transport by river transport, building materials, grain and metallurgy products prevail in the nomenclature. A certain impetus to the development of inland waterway transport was the adoption of the Law of Ukraine "On Inland Waterway Transport", which outlined the prospects for increasing the cargo turnover of river transport. Considering the volume of emissions from river transport, it is the most environmentally friendly compared to road transport. At the same time, the existing rolling stock of water transport is capable of replacing several thousand trucks. It has been established that the Dnieper basin plays the main role in the transportation of domestic cargo and passengers. More than 90% of all river transport in the country is carried out along the Dnieper and its largest tributaries Pripyat and Desna. However, the low operational characteristics of the fleet are one of the factors holding back the development of freight traffic on inland waterways. The four selected shipping companies provide cargo transportation on the Dnieper and Danube rivers, and are also capable of ensuring the potential development and competitive advantages of Ukrainian water transport.Conclusion. The studies carried out made it possible to substantiate the economic and environmental feasibility of transporting goods by inland water transport in Ukraine. Based on the determination of the share of transportations by inland water transport in the EU countries and Ukraine, the potential opportunities for the development of this area were established, taking into account other similar indicators, as well as the growth of export flows of grain and metallurgical products from the central part of Ukraine. Therefore, the development of domestic inland waterways is economically necessary, expedient and will have a positive effect for the entire country and the economy as a whole, given the low level of pollution and environmental pressure on air, land, water resources, biodiversity, which, in turn, affect climate change. , ecosystems in general and public health. Taking into account the total length of the navigable routes of Ukraine and the tendency to reduce the existing fleet, due to moral and physical aging, it is important to assist in attracting investments in the river fleet, will provide potential technical and technological opportunities for the development of all inland water transport and its key players.

Актуальность темы обуславливается важным значением рациональной организации перевозок для повышения эффективности работы судоходных компаний. При этом в качестве форм организации понимаются типовые организационные подходы согласования взаимодействия между различными объектами и элементами транспортной системы. В работе проводится анализ существующих подходов к выявлению устойчивых форм организации движения, их влияние на показатели работы транспортных компаний. Авторами отмечается снижение эффективности использования флота в России, переформатирование отношений в России между перевозчиками и грузовладельцами, нестабильность грузовой базы речного транспорта. Это привело к трансформации форм организации перевозок и движения флота. Поэтому многие теоретические положения в области организации работы речного флота нуждаются в адаптации к новым условиям и, следовательно, в доработке. В статье формулируются актуальные научные задачи, направленные на совершенствование научно-методического обеспечения системы организации речного судоходства в современных условиях. Предлагается система оценочных показателей, характеризующих организационные формы судоходства. Для оценки степени устойчивости схем движения судов предлагается использовать показатель, учитывающий число разных переходов судов между грузопотоками за определенный период и повторяемость этих переходов. Авторами также были сформулированы признаки, свойственной каждой из форм организации судоходства. Приводятся результаты экспериментальных расчетов оценочных показателей для крупной судоходной компании России «В.Ф.Танкер», занимающейся перевозками нефтегрузов. При этом были рассмотрены рейсы, выполненные танкерным флотом компании проекта RSD-27 за навигацию. The relevance of the topic is determined by the importance of rational organization of transportation to improve the efficiency of shipping companies. At the same time, typical organizational approaches to coordination of interaction between various objects and elements of the transport system are understood as forms of organization. The paper analyzes the existing approaches to identifying sustainable forms of traffic management, their impact on the performance of transport companies. The authors note the decline in the efficiency of fleet use in Russia, the reformatting of relations in Russia between carriers and cargo owners, and the instability of the cargo base of river transport. This led to the transformation of the forms of organization of transportation and fleet movement. Therefore, many theoretical provisions in the field of organizing the work of the river fleet need to be adapted to new conditions and, consequently, to be finalized. The article formulates actual scientific tasks aimed at improving the scientific and methodological support of the system of river navigation organization in modern conditions. A system of evaluation indicators that characterize the organizational forms of navigation is proposed. To assess the degree of stability of ship traffic patterns, it is proposed to use an indicator that takes into account the number of different transitions of ships between cargo flows over a certain period and the repeatability of these transitions. The authors also formulated the features inherent in each of the forms of navigation organization. The results of experimental calculations of estimated indicators for a large Russian shipping company "V. F.Tanker", which is engaged in the transportation of oil and gas cargo. At the same time, the flights performed by the tanker fleet of the RSD-27 project company for navigation were considered.

This paper explores the role of social media in tourist sentiment analysis. To do this, it describes previous studies that have carried out tourist sentiment analysis using social media data, before analyzing changes in tourists’ sentiments and behaviors during the COVID-19 pandemic. In the case study, which focuses on Andalusia, the changes experienced by the tourism sector in the southern Spanish region as a result of the COVID-19 pandemic are assessed using the Andalusian Tourism Situation Survey (ECTA). This information is then compared with data obtained from a sentiment analysis based on the social network Twitter. On the basis of this comparative analysis, the paper concludes that it is possible to identify and classify tourists’ perceptions using sentiment analysis on a mass scale with the help of statistical software (RStudio and Knime). The sentiment analysis using Twitter data correlates with and is supplemented by information from the ECTA survey, with both analyses showing that tourists placed greater value on safety and preferred to travel individually to nearby, less crowded destinations since the pandemic began. Of the two analytical tools, sentiment analysis can be carried out on social media on a continuous basis and offers cost savings.

L-Carnitine is an amino acid derivative that plays a key role in the metabolism of fatty acids, including the shuttling of long-chain fatty acyl CoA to fuel mitochondrial β-oxidation. In addition, L-carnitine reduces oxidative damage and plays an essential role in the maintenance of cellular energy homeostasis. L-carnitine also plays an essential role in the control of cerebral functions, and the aberrant regulation of genes involved in carnitine biosynthesis and mitochondrial carnitine transport in Drosophila models has been linked to neurodegeneration. Drosophila models of neurodegenerative diseases provide a powerful platform to both unravel the molecular pathways that contribute to neurodegeneration and identify potential therapeutic targets. Drosophila can biosynthesize L-carnitine, and its carnitine transport system is similar to the human transport system; moreover, evidence from a defective Drosophila mutant for one of the carnitine shuttle genes supports the hypothesis of the occurrence of β-oxidation in glial cells. Hence, Drosophila models could advance the understanding of the links between L-carnitine and the development of neurodegenerative disorders. This review summarizes the current knowledge on L-carnitine in Drosophila and discusses the role of the L-carnitine pathway in fly models of neurodegeneration.
