    The research investigates how organizational size influences the implementation of supply chain resilience and sustainability practices. While resilience and sustainability are increasingly recognized as interrelated priorities, existing literature often overlooks how firm size conditions strategic behaviour, particularly the distinct constraints faced by small and medium-sized enterprises (SMEs). To address this gap, the study employs a two-phase, mixed-methods approach. First, a structured literature review identifying the current state of academic research on the field. Second, a global survey of 252 supply chain professionals captures quantitative data across SMEs and large organizations. Statistical analysis tests three hypotheses regarding core aspects of driving resilience and sustainability outcomes. Findings show that large firms tend to formalize strategies more thoroughly, especially in risk detection and sustainability goal setting. However, SMEs demonstrate comparable resilience through informal, agile approaches and supplier collaboration. Overall, strategic effectiveness does not vary by firm size, but implementation pathways do. This study contributes original empirical evidence to the limited comparative literature on organizational size in supply chain strategy. By introducing size as a moderating variable, the research advances theoretical models and highlights the need for differentiated tools, policies, and partnerships. The findings aim to hold practical value for managers, and support businesses seeking to design scalable, inclusive approaches that enhance resilience and sustainability across the entire supply chain spectrum.

    At present, we cannot imagine a modern production process without computer support. At the same time, its integral part is the implementation of advanced and highly sophisticated production processes and technologies. Their aim is first and foremost to ensure quality production of products with high economic efficiency of the production process. EDM technology is one of the currently active progressive technologies. This is a technology that in practice is characterized by high product quality. The high quality of products not only through this progressive technology, but also other, whether conventional or progressive, is difficult to achieve without computer support. The aim of the paper is therefore to demonstrate the process of manufacturing a die-casting mould using progressive EDM technology using computer support.

    Globalization and the recent explosive development of technology have significantly changed people’s lifestyles resulting in an increase in the number of people living a sedentary lifestyle. COVID-19 pandemic has exacerbated the situation and created an unprecedented situation in the world. In the present study, we investigate changes in the physical activity and sedentary behavior of adult workers caused by the coronavirus epidemic. In our online cross-sectional research, we used snowball methodology. The target group of the survey was adult workers. 108 people filled in the questionnaire, the majority (73.1%) are women, the average age is 37.18 years and most of them have higher degrees (Diploma: 74%, PhD: 14%). The present study revealed a decrease in physical activity and an increase in sedentary time for the employees in our study. Despite respondents detected a decrease in their physical activity, an increase was reported in the proportion of online training participants. The majority of respondents partially, or totally switched to work from home during the pandemic, which may further increase their sedentary lifestyle. We did not find significant differences among the domain of work and leisure time or occupational physical activity patterns. The workplace is a great opportunity for promoting physical activity and reducing sedentary time in the adult working population, therefore it would be important for organizations, decision-makers and health professionals to work on the design of strategies to these goals.

    The manufacturing industry in Nigeria has been the so-called cornerstone of economic development since the sector has continuously played a major role in providing jobs and industrial capital. However, there remain issues that impede its progress, including inefficient resource use, unstable regulatory systems, and the need to comply with international market requirements. Specifically, it examined the effect of employee engagement, process efficiency, and resource allocation on Nigeria’s manufacturing sector. A survey research design was adopted, with a total population of 117 employees across five manufacturing firms. A total of 91 participants were administered a structured questionnaire. Data collected was analyzed using PLS-SEM. Findings revealed that employee engagement has the strongest effect on sustainable production (β = 0.412, t = 6.250, p < 0.000), followed by resource allocation (β = 0.237, t = 3.610, p < 0.000), and process efficiency (β = 0.174, t = 2.877, p = 0.004). It concluded that continuous improvement is significantly vital for sustainable production in the five sugar manufacturing firms studied in Nigeria. It is therefore recommended that management of these selected firms focus on developing unique resource allocation strategies, employee engagement, and process efficiency to ensure sustained workforce improvement, thereby achieving sustainable production outcomes.

    Green infrastructure measures improves the quality of surface and subsurface waters along with increasing the water balance on the town level. The aim of the study is to estimate the potential runoff quality improvement by applying stormwater BMP-s along traffic roads in the town. This is of high priority in the aquifer protection area where runoff water may infiltrate into the aquifer carrying pollutants from the surface. Estimations are applied: first we determine the surface of traffic roads, then estimate the quantity of different kinds of pollutants accumulated on the surface and thirdly we estimate the expected performance of the applied green infrastructure elements based on findings in the literature. We determine the impervious urban surface area associated with transport-related functions within the protected drinking water recharge area using GIS technic using orthophotos. We estimate the expected reduction of runoff pollution assuming that stormwater BMP-s are applied in the area. The overall goal is to make the significance of diffuse pollution more obvious and enhance drinking water protection through taking diffuse pollution into consideration.

    As urbanization accelerates, parking lots lead to stormwater runoff and localized flooding due to impervious layers and inefficient drainage. This case study evaluates stormwater management strategies across four parking lots in Debrecen, Hungary, to propose effective retrofitting solutions. The methodology combines visual site assessments with a comparative analysis of global best practices identified in the literature. Findings suggest integrating Green Infrastructure (GI) and Low Impact Development (LID) principles into parking lot design can enhance infiltration and significantly reduce surface runoff. Key recommendations include utilizing nearby vegetated depressions and replacing conventional concrete slabs with permeable surfaces. Beyond the flood avoidance, these strategies aim to reduce pressure on the local sewer system and minimize puddle formation.

    In this paper the surface of the prepared test specimens had been examined with light microscopy and surface roughness measurements. In order to improve the surface smoothness of PLA specimens, application of ethyl acetate was required. After this surface treatment, microscopic images were taken again. The melting and decomposition temperatures of the materials had been determined using derivatography. The chosen method was precision casting with gypsum molding. Also, the plaster molds had been burnt out according to the predefined melting and firing diagram. The measurement series shows that the samples produced by 3D printing can also be used in the field of precision casting. They provide greater freedom of design, more sophisticated pieces, and prototypes can be finished in a shorter amount of time.

    Increasing environmental volatility is a growing challenge for companies and businesses. The speed of economic events is changing, and the risk of uncertainty is increasing, requiring business to take a new approach to strategic planning. In the design and forming of their strategy, both the factors of the external and internal environment and the analysis of their competitors can be based on well-chosen methods. We consider the review of these methods, their application in planning and educational practice. The aim of our work, in which we present the methods that underpin the strategy applied in both domestic and international practice. The analysis of the external environment illustrates the construction and applicability of an external factor analysis matrix based on traditional PEST analysis and the Porter's five-factor model. In the case of internal factor analysis matrix, we focus on the approach of method choice, and on the applicable methods, the importance of the resource-based approach, the analysis of key factors and the Porter value chain analysis matrix. The third pillar of the analysis that underpins the strategy is the matrix-based assessment of competitors. The applicability of the methods depends on the form of the enterprise, the field of activity and the nature of its activities, which is complicated by the emergence of new economic spheres (e.g.: sharing) and transformed power relations.

    Automotive rubber products are subjected to large deformations during working conditions, they often contact with other parts and they show highly nonlinear material behavior. Using finite element software for complex analysis of rubber parts can be a good way, although it has to contain special modules. Different types of rubber materials require the curve fitting possibility and the wide range choice of the material models. It is also important to be able to describe the viscoelastic property and the hysteresis. The remeshing possibility can be a useful tool for large deformation and the working circumstances require the contact and self contact ability as well. This article compares some types of the finite element software available on the market based on the above mentioned features.
