This paper takes the form of a comparative life cycle assessment (LCA) analysis of 40-foot steel and composite containers based on GaBi® software. Reducing greenhouse gas emissions can be undertaken, among other things, by reducing the weight of the container, which is possible if lighter materials with comparable mechanical properties to steel are used. The LCA analysis allowed us to estimate the energy consumed and the amount of greenhouse gases emitted during the production of a steel and composite container. It turned out that the energy consumed in the production of the composite and steel container is practically equal in value, provided that carbon fiber from the polyolefin precursor is used in production. The processes with the highest energy intensity for container production are carbon fiber and COR-TEN A® steel production and processing. Changing the container material from steel to composite would save fuel and greenhouse gas (GHG) emissions into the atmosphere by 5.1 % and 18.3 % for road transportation and sea shipping, respectively.

The technique of acoustic emission has been shown to be useful for monitoring and measurement of transportation and mixing of feed concentrates and other ingredients. This method is ideally suited for flow/no flow alarm indicators, requiring no calibration and only basic electronic support. If the method is to be used for analysis of mixtures, the components must be sufficiently different in particle size or density. Besides that, the detection of particle breakdown and damage should be possible.

PL

Wykazano, że technika emisji akustycznej jest przydatna do monitorowania i pomiaru transportu oraz mieszania koncentratów paszowych i innych składników. Metoda ta idealnie nadaje się do wskaźników alarmowych przepływu/braku przepływu, nie wymagając kalibracji i jedynie podstawowego wsparcia elektronicznego. Jeżeli metoda ma być stosowana do analizy mieszanin, składniki muszą różnić się dostatecznie wielkością cząstek lub gęstością. Poza tym powinno być możliwe wykrywanie rozkładu i uszkodzeń cząstek.

Due to the various crises and the geopolitical situation, it is emphasized that it is necessary to create resilient supply chains through nearshoring. The effect of this is the shortening of supply chains in the area of purchasing materials and components, i.e. in the sphere of supply management relations. This should result in changes at the level of trade in the area of purchases. The aim of the article is to diagnose whether there is a tendency to reduce the volume of supplies with the increase in the distance of supply sources from the perspective of their overall structure. The context of the considerations is the European Union, with special focus on Poland. Time series analysis was used as a research method to detect the nature of the phenomenon represented by a sequence of observations, as well as classic descriptive statistics. It was inter alia found that no reduction in the burden on international supply chains was observed in Poland and the EU, expressed in the volume of trade exchange in terms of value. Additionally, no positive structural changes towards shortening supply chains were observed, despite an increase in transport costs and pro-environmental policy. The research may support decision-making regarding ways to strengthen resilience in goods flows. Previously, research on this topic was usually conducted in an aggregate form. The new research contribution is an analysis that takes into account such moderators as short and long flows.

PL

Z uwagi pojawiające się kryzysy różnej natury i sytuację geopolityczną podkreśla się, że konieczne jest tworzenie odpornych łańcuchów dostaw poprzez nearshoring. Efektem tego jest skracanie łańcuchów dostaw w przestrzeni zakupów materiałów i komponentów, czyli w sferze relacji zarządzania dostawami. Powinno to skutkować zmianami na poziomie wymiany handlowej w obszarze zakupów. Celem badania jest zatem zdiagnozowanie, czy istnieje tendencja do mniejszego obciążenia łańcucha dostaw z punktu widzenia dostaw międzynarodowych, czyli importu towarów. Przedmiotem rozważań jest Unia Europejska ze szczególnym uwzględnieniem Polski. Jako metodę badawczą do odkrywania natury zjawiska reprezentowanej przez sekwencję obserwacji oraz klasyczną statystykę opisową wykorzystano analizę szeregów czasowych. Stwierdzono m.in., że w Polsce i UE nie obserwuje się zmniejszenia obciążenia międzynarodowych łańcuchów dostaw wyrażonego wartościowo wolumenem wymiany handlowej. Dodatkowo, pomimo wzrostu kosztów transportu i polityki prośrodowiskowej, nie zaobserwowano pozytywnych zmian strukturalnych w kierunku skracania łańcuchów dostaw. Badania mogą pomóc w podejmowaniu decyzji dotyczących sposobów wzmocnienia odporności w przepływach towarów. Dotychczas badania na ten temat były prowadzone przeważnie w formie zagregowanej. Nowym wkładem badawczym jest dokonanie analizy uwzględniającej takie moderatory jak przepływy krótkie i długie.

The purpose of the article is to show changes in the operation of Polish large and medium-sized road carriers in the context of the EU's pro-environmental requirements contained in the Green Deal in the post-pandemic period. The decline in the number of transport orders resulting from the general slowdown in the economy during the COVID-19 pandemic undoubtedly had an impact on the turnover of road carriers and, consequently, on funding for investment projects, including environmentally friendly investments. Verifying the magnitude and direction of such changes seems a much-needed aspect of the research in the context of the Green Deal's unchanging high demands. The research that was conducted shows the impact of the pandemic on the investment decisions and activities of transport companies and the reality of post-pandemic transport. The practical application of the research results is very useful, primarily as guidance for road carriers in the context of Green Deal.

Celem artykułu jest ukazanie zmian w funkcjonowaniu polskich dużych i średnich przewoźników drogowych w kontekście wymogów prośrodowiskowych UE zawartych w Zielonym Ładzie w okresie postpandemicznym. Spadek liczby zleceń transportowych wynikający z ogólnego spowolnienia gospodarki w czasie pandemii Covid-19 niewątpliwie wpłynął na obroty przewoźników drogowych, a w konsekwencji na finansowanie projektów inwestycyjnych, w tym inwestycji przyjaznych środowisku. Weryfikacja skali i kierunku tych zmian wydaje się bardzo potrzebnym aspektem badań w kontekście niezmiennie wysokich wymagań Zielonego Ładu. Przeprowadzone badania pokazują wpływ pandemii na decyzje inwestycyjne i działalność firm transportowych oraz postpandemiczną rzeczywistość w transporcie. Praktyczne zastosowanie wyników badań jest bardzo przydatne, przede wszystkim jako wytyczne dla przewoźników drogowych w kontekście Zielonego Ładu.

This study embarks on a profound investigation into the experiences and challenges confronted by individuals with disabilities. It emphasizes their interactions with architectural structures and their engagement with assisting technologies. Based on a meticulously curated survey, the study reveals that the educational background of respondents is diverse, with secondary education emerging as the most prevalent. A significant segment of the sample, 48%, is identified with a profound degree of disability (I disability group), underscoring the need to address their unique challenges. Key findings highlight a range of architectural barriers, with stairs lacking alternative access methods as the primary impediment. This highlights the urgency for urban planning and infrastructural updates tailored for inclusivity. The frequency of outdoor activities, predominantly daily, provides insights into mobility patterns and potential challenges faced. On the technological front, the survey reveals a disparity in the adoption and satisfaction levels with assisting technologies. Only a small minority use these tools daily, with a significant segment expressing inadequacy or partial alignment with their needs. Interestingly, a pronounced affinity towards these technologies is observed among higher educated individuals, suggesting potential links between education and technological engagement. Furthermore, the study explores the intricacies of architectural barriers in residential areas. Larger cities, for instance, present unique challenges, such as the lack of appropriate voice signaling. Such insights advocate for location-specific interventions. This research provides a comprehensive understanding of the diverse challenges faced by individuals with disabilities in Poland. By integrating these insights, the study emphasizes the need for holistic and targeted solutions, laying the foundation for creating an inclusive and accessible societal environment. This paper also aims to explore the logistics of transport services for people with disabilities in Poland, focusing on their availability, accessibility, cost, regulations, and the awareness and education surrounding these services. By examining these factors, this paper seeks to identify the challenges faced by people with disabilities when using transport services in Poland and suggests measures to enhance the logistics of these services.

Niniejszy artykuł przedstawia analizę doświadczeń i wyzwań, przed którymi stoją osoby niepełnosprawne. Podkreśla ich interakcję z obiektami architektonicznymi oraz zaangażowanie w technologie wspomagające. Badanie wykazało, że wykształcenie respondentów jest zróżnicowane, jednak dominuje wykształcenie średnie. Znacząca część próby, aż 48%, identyfikuje się ze znacznym stopniem niepełnosprawności (I grupa niepełnosprawności), co podkreśla potrzebę sprostania ich wyzwaniom. W opracowaniu wskazano na szereg występujących barier architektonicznych, z których główną są schody, bez alternatywnych metod dostępu. Podkreśla to pilną potrzebę planowania urbanistycznego i aktualizacji infrastruktury, dostosowanych do specjalnych potrzeb. Analiza częstotliwości aktywności na świeżym powietrzu, głównie codziennych wyjść, pozwoliła na określenie wzorców mobilności osób niepełnosprawnych oraz zidentyfikowanie potencjalnych wyzwań, z jakimi się borykają. Badania wykazały istotne różnice w adaptacji i poziomie zadowolenia z technologii wspomagających; tylko niewielka część respondentów korzysta z tych narzędzi codziennie, przy czym znaczna ich część wyraża niedostosowanie lub częściowe dostosowanie do swoich potrzeb. Przywiązanie do tych technologii obserwuje się wśród osób z wyższym wykształceniem, co sugeruje potencjalne powiązania między edukacją, a zaangażowaniem technologicznym. Ponadto, badanie wskazuje na bariery architektoniczne w miejscach zamieszkania respondentów. Na przykład, w większych miastach stanowią one większe wyzwania dla osób niepełnosprawnych, takie jak brak odpowiedniej sygnalizacji głosowej. Badanie wskazuje na potrzebę opracowania rozwiązań dostosowanych do specyficznych warunków lokalnych. Przeprowadzone badanie umożliwia wskazanie wyzwań, z jakimi borykają się osoby niepełnosprawne w Polsce. W opracowaniu podkreśla się potrzebę całościowych i ukierunkowanych rozwiązań, które mogą przyczynić się do stworzenia dostępnego środowiska społecznego dla osób niepełnosprawnych. Celem artykułu jest m.in. ocena logistyki usług transportowych dla osób niepełnosprawnych w Polsce, ze szczególnym uwzględnieniem ich dostępności, przystępności cenowej, kosztów, aż po świadomość i edukację na temat tych usług. Analizując te czynniki, artykuł podejmuje próbę zidentyfikowania wyzwań stojących przed osobami niepełnosprawnymi podczas korzystania z usług transportowych w Polsce i proponuje działania, które mogą usprawnić logistykę tych usług.

The article presents the issue of the transport of goods in relation to sea transport. Sea transport has been known to mankind for a long time. Currently, maritime transport is not limited only to the transport of goods and/or passengers along sea routes, which are carried out between seaports using appropriately adapted means of transport. It is a branch of transport, which consists of a very good knowledge of navigation, highly specialized staff, and a wide range of containers for transporting various types of cargo, often requiring specialized conditions. In addition, sea transport is perfectly combined with intermodal transport, so that in the end, the transport process is the most beneficial for all participants, i.e., the customers, sellers, distributors, and manufacturers. The main purpose of the article was to present the volume of goods transported in this branch of transport. The article, after introducing the issue, presents the classification of sea vessels, refers to the market of maritime transport services and its conditions for further development, and analyzes the overall volume of goods transported in the seaports of Gdańsk and Gdynia against the background of other Polish seaports in the years 2011-2021.

The activities of transport operations exhibit both positive and negative outcomes. Its negative effects on human health and the sustainability of the environment are of interest in this study. As a result, the study investigated the influence of transport operations on the changing local climate in Nigeria's southwestern cities. It investigated motorists' socioeconomic status (SES) and travel characteristics; the salient components of transport operations contributing to greenhouse gas emissions (GHG emissions); the effect of GHG emissions from transport operations on the local climate; transport externalities contributing to local temperature changes; and the effect of GHG emissions from transport operations on human health in the research location. This study employed a cross-sectional research design, utilizing systematic sampling to collect 580 copies of questionnaires administered to commercial motorists found in queues across two randomly selected parks in each capital city within the region. Both descriptive and inferential statistics (ANOVA and Linear Regression) were used to analyze the data. The study found that 60% of the motorists were middle-aged (aged between 36 and 45). The majority (70%) drive an average of 100 to 150 km, and premium motor spirit (PMS) is the primary source of energy for 95% of them. The nature and condition of the fuel in use are the top-ranked components of transport operations contributing to GHG emissions. The result of the ANOVA revealed a significant variation among the components of transport operations contributing to GHG emissions (F = 28.302, p = 0.000<0.05). Meanwhile, the linear regression results indicate that vehicular GHG emissions have a significant impact on the local climate (F1⁄578=30.091, p=0.000<0.05). Traffic congestion and bad road conditions were the top-ranked transport externalities contributing to the changing local climate. The most common effects of GHG emissions on human health were headaches and difficulty breathing. Considering these findings, this study suggests the best tactics to lessen the effects of GHG emissions from transport operations, which adversely affect the local climate and human health in the study area.

With a growing number of coronavirus patients worldwide, military and civilian transport aircraft are increasingly being used for civilian medical evacuation duties (MEDEVAC) on time-critical flights. This article deals with the possibility of converting an aircraft fleet in the Czech Republic to MEDEVAC. The indication for the analysis of the possibility of transforming transport aircraft was the past and current pandemic situation in the Czech Republic. The main research question is how to implement the modification of a selected airline of the Czech Republic to MEDEVAC. An analysis of the technical data of selected aircraft from Airbus and Boeing was used to investigate this problem. Further, an analysis of the medical equipment required for the MEDEVAC aircraft category was also performed using equipment manufactured in the Czech Republic. The results obtained by the analysis and spatial arrangement of the aircraft deck for the transport of patients with medical equipment confirmed the possibility of such a transformation within the Czech Republic. We consider it important to elaborate on a project that would solve, in detail, all the steps of the conversion of a transport aircraft to MEDEVAC.

Purpose: Nowadays there is still low awareness of creating specific supply chain hybrids in a planned manner. This paper focuses on a hybrid of the gresilient chain, which reflects the trend to act for the well-being of the environmental to eliminate disruptions in the flow of goods. The aim of the study is to determine the interdependence of the factors shaping the resilience of the supply chain and to determine which of them contribute the most to the creation of a green chain. Design/methodology/approach: AHP and DAMATEL were used as research tools. A study focused on the cognitive chain is extremely interesting, because it is a global chain in which the main coordinator is relatively small. The subject of the research is the international supply chain of a company that conducts research on engine oils, coolants and fuels for gas engines driving turbines, electric and wind turbines, hydraulic transmissions, etc. Findings: As a result, among other things, it was established, that speed is the factor that is most sensitive to the influence of other factors and, at the same time, the most important from the point of view of recipients. In addition, it was proven that redundancy is essential for creating resilience in the analyzed chain, while transparency is necessary for creating the green chain. It has also been shown that redundancy and cooperation work simultaneously to a great extent for the benefit of both chains. Research limitations/implications: Every supply chain requires a separate study. Practical implications: The results can help managers in implementing the gresilient strategy or in modifying it if it has already been implemented. The work carried out may contribute to the creation of a general matrix containing paths to the expected types of supply chains, taking into account the specificity of input and output connections. Social implications: Gresilient chains are part of the idea of corporate social responsibility. Originality/value: From the standpoint of building up resilience, this is an interesting case, because it is the discussed case does not fit into the concepts of popular models in which agility is promoted as the one that guarantees the resilience of the chain. The study is an expanding knowledge in the field of the gresilient chain, in which research is lacking due to the initial stage of science in this area.
