The Scientific Journals (SJ) issued by the Maritime University of Szczecin (MUS) is a magazine which presents results of MUS research and educational activities. SJ has been published since 1973 but in 2004 it changed the ISSN from 0209-2069 to 1733-8670 as a result of MUS changing its name from Wyższa Szkoła Morska w Szczecinie to Akademia Morska w Szczecinie.
At the beginning there were several papers published in SJ and they were connected with maritime affairs. Doctoral and habilitation theses had also been published then. With time the SJ scope expanded to among others nautical issues, operation of the vessel, marine power plant operation. The magazine presented also symposium and conference proceedings.
Since 2008, the magazine has been published in A4 format with a new layout. Since 2010 the journal has been publishing the articles in English. By the end of 2014 a total of 112 Scientific Journals will have been published.
The SJ Scientific Board ensures high quality of published papers. All papers are reviewed confidentially and anonymously (double blind review) and are a subject of scientific edition.
The Scientific Journals printed version is primary.

(Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Politechniki Morskiej w Szczecinie, )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.

(Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Politechniki Morskiej w Szczecinie, )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.

(Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Politechniki Morskiej w Szczecinie, )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.

(Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Politechniki Morskiej w Szczecinie, )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.

(Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Politechniki Morskiej w Szczecinie, )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.

(Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Politechniki Morskiej w Szczecinie, )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.

(Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Politechniki Morskiej w Szczecinie, )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.

(Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Politechniki Morskiej w Szczecinie, )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.

(Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Politechniki Morskiej w Szczecinie, )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.
