This paper presents a statistical and comparative analysis of occupational accidents, incidents, and occupational diseases in the advertising production sector and related industries in Romania over the period 2010–2025. Although advertising activity itself has a relatively low incidence rate of accidents, related activities—such as printing, material processing, and outdoor installation—involve significant occupational risks. The study integrates data provided by the Labour Inspectorate and the National Institute of Statistics, as well as Eurostat, to identify trends, risk typologies, and determining factors. The results highlight a transition from mechanical hazards toward chemical and technological risks, underlining the need to adopt modern prevention strategies and digital training solutions.
The increase in automation in modern production systems requires an integrated approach to maintenance and energy management, in order to maximize operational efficiency and reduce environmental impact. In this context, the article presents the development of a maintenance plan for an automated line, analyzed from the perspective of an Industrial Energy Management System (IMES). The paper highlights the role of energy-oriented maintenance, the typologies of interventions (preventive, predictive and condition-based), as well as the relevant energy performance indicators. An application case study on an automated final assembly line is presented, including concrete maintenance recommendations for electronic assemblies and critical equipment. The results demonstrate that the integration of IMES in maintenance planning leads to the optimization of energy consumption, increased equipment reliability and supports the transition to sustainable industrial production.
The paper presents the design and virtual simulation of a mechanical lower-limb prosthesis developed using three-dimensional modeling tools. The study focuses on the geometric construction of the prosthetic components and on the realization of animation sequences in order to simulate the flexion and extension of the knee joint. A digital prototype was created and assembled in a CAD environment, followed by the definition of motion constraints that reproduce the real mechanical behavior of the prosthetic joint. The animation allowed the observation of angular displacement, alignment between components, and possible interference during movement. The results highlight the usefulness of virtual simulation in validating prosthetic motion before physical fabrication.
Within this paper, starting from two bio-based matrices, composite materials reinforced with cotton fibers will be manufactured. The hand lay-up technique will be used, and the final composite will be obtained by casting. After producing a composite plate, specimens will be cut and subjected to both destructive and non-destructive testing in order to determine the mechanical properties. The influence of the bio-based matrices on the mechanical properties will be discussed.
The accelerated transformations of the digital work environment have led to the emergence of emerging occupational risks, insufficiently addressed within traditional occupational safety and health methodologies. Among them, digital fatigue stands out as a complex phenomenon, driven by prolonged exposure to screens, high cognitive load, intensity of digital interactions, and multitasking specific to knowledge-based activities. This paper proposes an integrated approach to assessing this risk, by developing a quantitative model based on the Digital Fatigue Index (DFI), capable of capturing the dynamic and cumulative character of the phenomenon. The proposed model uses a mathematical formulation and a differential equation to describe the evolution of digital fatigue over time, including both accumulation and recovery processes. The conceptual validation of the model was achieved by simulating a typical scenario of working in a digital environment, highlighting the influence of factors such as frequent interactions and multitasking on the accelerated increase in fatigue. The results obtained underline the importance of introducing breaks and optimizing the organization of work to reduce the associated risks. Finally, the paper highlights the need to integrate digital fatigue into occupational risk assessment and provides a useful analytical tool to support occupational safety and health decisions in the context of the digital economy.
