In an era of constantly changing needs and challenges posed by urban stakeholders and an increasing number of vehicles in the area, transport accessibility has started to play a key role. Shaping transport infrastructure in cities is one of the greatest challenges city managers have. In recent years, the introduction of paid parking zones (PPZs) has become an increasingly common solution. This paper aims to assess the impact of parking fees on the mode choice of users of urban spaces. As part of the research process, a systematic review of literature in the area outlined above and an analysis of transport accessibility in the selected area are carried out. This paper presents the results of a survey on the determinants of transport mode choices in the city of Szczecin. The results show that, despite high rates imposed by city authorities, users of urban spaces still choose to travel by car to their destinations and that parking fees do not have a real impact on modal shift. These results offer valuable insights for both drivers and local authorities in terms of creating transport accessibility for the final stage of this journey ‒ i.e., parking accessibility.

The maritime transport of dangerous goods (DG), including hazardous and noxious substances (HNS), poses escalating environmental and legal challenges, particularly in Southeast Asia’s high-traffic corridors. While international frameworks such as UNCLOS, MARPOL, and the IMDG code impose clear obligations, ASEAN member states exhibit fragmented implementation and limited HNS-specific preparedness. This paper critically assesses the region’s regulatory landscape through a legal-doctrinal and theoretical lens, identifying gaps in treaty ratification, port state control, and regional cooperation. It argues that soft-law mechanisms and institutional inertia undermine effective risk governance. This study calls for a binding regional instrument on HNS response, harmonized inspection regimes, and integrated liability frameworks to align ASEAN practices with global marine protection standards. Accordingly, the purpose of this work is to examine how ASEAN’s approach to DG transport aligns with international maritime law and to propose reforms that strengthen both regional and global marine environmental governance.

AlSi9Mg silumins are increasingly used in lightweight ship structures and onboard equipment, where resistance to impact and vibration is crucial. This study evaluates the effect of AlSr10 (0.15 and 0.30% Sr) and AlB4 (0.20% B) additions on the microstructure, impact strength and fracture behavior of the AlSi9Mg alloy. The highest improvement in impact strength—from 4.8 to 11.1 J/cm²—is achieved with 0.30% AlSr10. The lamellar eutectic β(Si) transformed into a fine fibrous morphology, reducing interphase spacing and producing a more tortuous fracture profile, which enhanced dynamic load resistance. While the AlB4 addition shortened α(Al) dendrites, it did not significantly improve impact strength (4.13 J/cm²). The results demonstrate that a properly selected Sr level enables the design of components (e.g., brackets, housings, and guards) for marine environments subjected to impact and vibration. This work provides a basis for future investigations into long-term durability of modified silumins under corrosive marine conditions and combined impact–vibration loads specific to waterborne transport.

The purpose of this study is to propose and verify the feasibility of using gray relative analysis (GRA) to identify key characteristics of an industrial maintenance system and key factors for managing human reliability in this system. The developed approach is verified using qualitative and quantitative data obtained from seven companies in the furniture industry. Through the approach used, the following maintenance characteristics are identified as key: scheduling intensity index, work scheduling intensity index, and work request response index. In addition, the following human reliability management factors are identified as key: analysis of error reduction measures, implementation of error reduction measures, and evaluation of the effectiveness of implemented human error reduction measures. The approach verified in this paper is computationally simple and beneficial in cases of imprecise and incomplete information and small sample size, while the results obtained are easy to interpret. This approach can, therefore, be a crucial tool for improving enterprises in maintenance and in terms of improving human reliability. The application of GRA in human reliability management in industrial maintenance is original.

This paper aims to present the potential for integrating the classic Kano method with artificial intelligence tools to support customer needs research and segmentation for manufacturing companies. This research provides a literature review of the Kano method and AI technologies used to analyze customer data. A case study conducted at a Polish manufacturing company in the SME sector explored ways to better align offerings with market expectations. The study is based on identifying product features and developing a Kano questionnaire, followed by the use of popular chatbots (i.e., ChatGPT, Copilot, and Gemini) to automatically assign these features to the appropriate Kano model categories. The data originates from online surveys and direct contact at points of sale. The results of the automated analysis are compared with traditional results, assessing the compatibility of both approaches. The paper demonstrates that integrating these two methods significantly improves the decision-making process for product development, increasing the precision of customer needs identification and the effectiveness of implemented innovations.

Motivation is a key element of effective human resources management in virtually every industry. Properly motivated employees are more engaged, productive, and loyal to the organization. The purpose of this article is to demonstrate the importance of employee motivation as a key element of the organizational management process, with particular emphasis on its impact on work efficiency, team engagement, and the achievement of operational and strategic goals. This article also examines various motivational tools and models used in selected economic sectors (i.e., services, manufacturing, utilities, and transportation). It compares motivational practices across sectors, identifying similarities and differences, and indicates which mechanisms are most effective under specific conditions, which constitutes the author’s scientific contribution. It also presents factors that influence employee motivation in enterprises across various industries. A survey has been developed for this publication, in which employees responded to questions regarding the impact of management behavior on motivation. Based on the author’s own observations and survey questions, the motivational needs of employees in a manufacturing company and the transportation industry in the Silesian Voivodeship are analyzed.

The need to reduce greenhouse gas emissions in various sectors, including road transport, has resulted in the development of investments relating to the use of hydrogen as a fuel in motor vehicles. Currently, there are six hydrogen refueling stations located in Poland, and the construction of another 13 is in the planning phase. By storing flammable gas, these facilities may pose a threat to the environment, in particular, if they become the target of foreign armed forces or terrorist activities. This article presents the effects of an event that resulted in the mechanical damage of a compressed hydrogen tank. The ALOHA program is used to analyze the impact of the threat. Two event scenarios are considered for summer and winter conditions. The simulation results indicate that the most dangerous effect of the attack may be the overpressure resulting from the explosion of the vapor cloud, ignited as a result of detonation after the leakage of the tank. It is, therefore, reasonable to designate safety zones around such objects in order to minimize the effects of accidental release.

This study addresses the machining challenges of Hadfield steel by optimizing wire electrical discharge machining (WEDM) parameters through a robust, multimethod approach. The research niche lies in applying hybrid modelling and optimization strategies ‒ specifically combining statistical and soft computing techniques ‒ to enhance machinability of high-manganese steels. The main objective is to improve both material removal rate (MRR) and surface roughness (SR) through systematic parameter tuning. The methodology integrates Taguchi L27 orthogonal array, analysis of variance (ANOVA), and genetic algorithms (GAs) to analyze and optimize five key process parameters: tₒₙ (pulse-on time), tₒff (pulse-off time), gap voltage (Vg), wire feed rate (Wf), and dielectric pressure (Dp). Results revealed that tₒₙ, tₒff, and Vg significantly influenced MRR and SR, while Wf and Dp had negligible effects. The maximum MRR of 36.25 mm²/min (+249.57% from baseline) is achieved under optimal conditions (tₒₙ = 120 µs, tₒff = 30 µs, and Vg = 80 V). The lowest SR of 0.95 µm (46% improvement) is achieved at tₒₙ = 100 µs, tₒff = 40 µs, and Vg = 60 V. Multiobjective optimization using MATLAB’s fmincon solver and GA-based regression modeling yielded a balanced result (MRR = 14.92 mm²/min and SR = 1.76 µm). The SEM imaging and 3D surface topography analysis confirmed that higher SR correlated with craters, microcracks, and cavities due to thermal loading. This work highlights MATLAB’s fmincon optimization combined with genetic algorithm-based modeling as a powerful framework for process optimization, especially for complex geometries such as grooves and splines in Hadfield steel, and underscores both the potential and limitations of WEDM in machining hard-to-cut materials.

The need to search for alternative packaging for takeaway food in the HoReCa sector (i.e., hotels, restaurants, and catering) strictly relates to EU regulations. Directive (EU) 2019/904 prohibits placing on the EU market nine types of single-use plastic products, including food containers intended for consumption onsite or takeaway made of expanded polystyrene (EPS). This research aims to assess the possibility of replacing the EPS box with other packaging. A specific goal of this study is also to compare packaging in terms of the rate at which they transfer thermal energy by heat conduction. The experimental data were described by Newton’s law of cooling, based on which the constant k of each object (a food simulant in a certain type of packaging) is determined. When assessing substitutes, the thermal insulating properties of the packages are investigated, as well as their ability to maintain shape and tightness after contact with semi-liquid food. The availability of the selected packaging on the local market and its price are also considered. The research has shown that disposable packaging for takeaway food is currently more useful than reusable options. The packaging variants, which are confirmed as suitable for cooked solid dishes with semi-liquid additives, are ranked in the following order according to their utility index (largest to smallest): PPmet bag, XPS menubox, AL bag with PP tray, PAP/ PE bag, PP reusable container, GL reusable container, PAP/AL envelope, PP box, and rPET container. This study indicates the need for further research into innovative packaging for takeaway food, including lowering the weight of existing materials while simultaneously increasing their thermal insulation or searching for new bio-based materials.

This article presents a comparative analysis of the creation of digital bathymetric models using multispectral bands. The case analyzed involves images acquired from low altitude using an unmanned aerial vehicle in an area of shallow inland waters. The use of an underwater photogrammetric network enables georeferencing of the datasets at a level no worse than 0.013 m (mean RMSE). The green and red bands make it possible to generate a dense point cloud in the full bottom area and create DBMs, the accuracy of which is examined on the basis of 22 bottom check points and the obtained accuracies for the RMS error are no worse than 0.24 m. The results of this study indicate that the green and red bands can be used for bathymetry acquisition in shallow and very shallow waters, which can be applied to work that requires accurate bathymetry reconstruction in these types of water bodies.

This article concerns the development of autonomous ship technology in maritime navigation, which entails safety and risk management challenges. This study aims to compare the risk analyses of two levels of autonomy of seagoing ships – A3-B1 (ships with limited crew) and A2-B0 (ships fully unmanned) – based on the results of a project named SAFEMASS developed by DNV GL company for the European Maritime Safety Agency. In addition, identifying new, emerging risks relating to the functioning of MASS is another research goal. The article uses hazard identification methods (HAZID) and fault tree analysis (FTA). In the case of A3-B1 vessels, the main threats result from reduced situational awareness of operators and dependence on automatic systems. In the A2-B0 model, the most significant risks are communication system failures and a lack of physical supervision of processes. The research results indicate the need to implement additional risk control measures, such as system optimization and improvement of human-machine interfaces (HMI). It is suggested that autonomous and low-emission technologies will develop conceptually in the coming years. Still, the widespread implementation of these technologies will take a long time due to the complexity of the processes and high operating costs. This article emphasizes that implementing autonomous technologies is a promising path for the sustainable development of maritime transport. Still, further research is required, investment in infrastructure is needed, and legal regulations must be adjusted.

This paper presents considerations for maintaining the necessary distance behind the preceding vehicle in traffic. The special case of the need to exit a motorway from the left-hand lane when there is heavy traffic is analyzed and evaluated. The legislation uniquely does not address such a case. In addition, the special case of entering a motorway has been analyzed and evaluated. When operating vehicles on the roads, we are exposed to non-compliance with the rules and the resulting offences and accidents. The human factor and unreasonable and “out of life” rules contribute enormously to their occurrence. These are from the area of the active safety system in the operation of vehicles on the road. The conclusions point to the need to change the provisions in the current road traffic law and to provide training for car drivers.

This article discusses the fire hazard of motor yachts that are up to 15 meters long. These types of recreational units, in accordance with legal regulations, are not subject to safety inspections. This may lead to negligence that results in a fire within a unit. The construction material most commonly used in the construction of yachts is glass fiber-reinforced plastic, used to produce components such as the hull, deck, and superstructure of motor yachts. The yacht’s equipment, such as furniture and other components, is made, among others, of wood, wood-based materials, or plastics. The results of the flammability tests of such materials presented in this article indicate the need to minimize the risk of fire, the effects of which may be dangerous both to human health and life, as well as the environment
