1. Injury prevention in pre-primary and primary education : an analysis of teachers' perspectives and expertiseBarbora Loudová Stralczynská, Kateřina Chroustová, Martin Bilék, Vlastimil Chytrý, Tereza Krčmářová, Jana Krátká, 2025, original scientific article Abstract: The article presents a study focused on the teaching staff and the impact of their occupational health and safety (OHS) teaching on pupils in pre-primary and primary education. A questionnaire survey was conducted among 227 teachers from eleven pre-primary and primary schools in Prague, Czech Republic in 2021. Pre-primary teachers rated themselves as more competent in OHS than teachers of primary education, although pre-primary children had a higher rate of injuries. More frequent OHS training did not affect teachers' self-assessment but reduced child injury rates, especially if such training was completed more than once a year.

3. Sustainable approach to occupational health and safety careSimona Šarotar Žižek, Matjaž Mulej, Ana Marija Gričnik, 2024, review article Abstract: Occupational Safety and Health (OSH) careis not requisitely holistic if it is not sustainable. Hence SOSHis suggested as a novel approach to the management of individuals, with a particular emphasis on the long-term aspects of occupational safety and health, as well as the principles of regeneration and renewal. SOSH improves a company's ability to recruit and keep high-quality employees: companies create attractive and unique employer brands through the incorporation of SOSH practises into their employee value proposition, mission, and vision. SOSH emphasizes the humane treatment of individuals, emphasising their health, safety, and overall well-being. SOSH facilitates the development of a company in a sustainable and sustained manner. Furthermore, it also encompasses other significant aspects, such as the safety, health, and well-being of employees, employability, justice, employee development, and employee participation, among others. Sustainability, social responsibility, dialectical systems theory, and its law of requisite holism all contribute to the creation of SOSH, which is a new knowledge-cum-values management approach to OSH. No similar concept is offered in the existing literature.

4. Overview of the Patents and Patent Applications on Upper Guardrail Protection Systems for MotorcyclistsLaura Brigita Parežnik, Marko Renčelj, Tomaž Tollazzi, 2025, original scientific article Abstract: Upright-posture motorcycle crashes against steel safety barriers (SSBs) often result in severe upper-body injuries due to the sharp upper edge of the rail. While solutions for sliding crashes on curves, called a ‘motorcyclist-friendly barrier’, are already implemented in practice, protective measures for upright-posture impacts remain underdeveloped. This study systematically reviews patents and patent applications addressing upper guardrail protection for motorcyclists. We identified and analysed a small number of existing innovations aimed at mitigating the consequences of upright crashes. The selected solutions were evaluated according to their technical design, ease of installation, potential for recycling, environmental compatibility, and expected costs. Our comparative analysis reveals that while some patents or patent applications offer promising features, such as flexible caps, bent plates, or modular attachments, none comprehensively address all safety, environmental, and economic requirements. The findings provide a basis for further development of motorcyclist-friendly SSB designs and suggest specific criteria that should be included in future guidelines and standard updates.

5. Perceptions of patient safety culture among triage nurses in the emergency department : a cross-sectional studyZvonka Fekonja, Sergej Kmetec, Nataša Mlinar Reljić, Jožica Černe Kolarič, Majda Pajnkihar, Matej Strnad, 2023, original scientific article Abstract: The patient safety culture is key to ensuring patient safety in healthcare organizations. The triage environment is inherently demanding for patient safety and is characterized by high stress, rapid decision-making, and quick action. In several countries, including Slovenia, there is a lack of studies on the patient safety culture among triage nurses. This study aimed to assess the perceptions of the patient safety culture among triage nurses. A cross-sectional survey design was used. The Emergency Medical Services-Safety Attitudes Questionnaire, distributed to triage nurses, was used to collect data. A total of 201 triage nurses participated in this study. The results revealed that the overall average perception of the patient safety culture was 57.27% (SD = 57.27), indicating that the perception of the patient safety culture among triage nurses in the emergency department was non-positive and requires improvement. “Job Satisfaction” received the highest score (63.18%; SD = 17.19), while “Working Conditions” received the lowest (49.91%; SD = 17.37). The perception of positive and negative safety culture responses was statistically significant for age (χ2 (3) = 17.750, p ≤ 0.001), education (χ2 (2) = 6.957, p = 0.031) and length of working experience (χ2 (3) = 8.875, p = 0.031). The findings emphasize the significance of improving the safety culture in relation to several areas of patient care during the triage process. This research serves as a crucial foundation for enhancing patient safety in triage, providing quality care, and reducing adverse events.

6. Harnessing environmental yeasts - Pichia kudriavzevii strain ZMUM_K002 : the quest for isolates with properties for efficient biotechnological applicationsTadeja Vajdič, Marjanca Starčič Erjavec, 2025, original scientific article Abstract: The environment hosts a diversity of microorganisms whose potential for biotechnological applications has not yet been exhausted. The quest of our study was to find isolates of Pichia kudriavzevii from the environment that could be used as new biotechnological agents. Moreover, we aimed to explore the resource efficiency for microbial cultivation, in particular the efficiency of spent coffee grounds (SCG), an easily accessible waste coffee product with a high unutilized organic content. In this study, Pichia kudriavzevii strain ZMUM_K002, a yeast strain isolated from a grape pomace compost, was investigated. Antifungal susceptibility, particularly fluconazole susceptibility, was assessed, and the strain’s biotechnological potential by comparing its ability to utilize low-cost carbon sources, including SCG, with a natural isolate of Saccharomyces cerevisiae (strain ZMUM_K003) was assessed. The P. kudriavzevii strain ZMUM_K002 exhibited higher fluconazole susceptibility and yielded more than 30% more biomass in optimized media formulations compared to S. cerevisiae ZMUM_K003. These findings demonstrate that P. kudriavzevii ZMUM_K002 has the potential for efficient biomass production in sustainable industrial biotechnology, particularly in processes requiring high biomass yields on alternative substrates.

7. A preliminary assessment of rider/driver gaze behaviour in slovenian urban areasTomaž Tollazzi, Matej Moharić, Chiara Gruden, 2022, original scientific article Abstract: Motorcycle riders are an increasing group of road users. The intrinsic characteristics of
powered two wheelers (PTW) allow them to be particularly flexible, both in urban and extra-urban
environments. Nevertheless, crash statistics indicate that riders involved in road accidents are highly
likely to suffer severe injuries, underlining the vulnerability of this group of road users. An element
that can greatly affect the safety of PTW users is road design, as roads are usually designed for
two-track vehicles (cars, buses, and lorries) and do not consider the needs of PTWs. Additionally,
handling a motorcycle is quite different from driving a car; thus, the behaviour of riders is different to
that of drivers. The aim of this paper is to compare how different road designs are perceived by riders
and drivers and to preliminarily assess if riders’ behaviour and attention allocation are related. For
the purpose of this research, an eye-tracking experiment was developed outdoors. Both drivers and
riders travelled along a route comprising four different road designs and various road layouts, and
the output was analysed both qualitatively and quantitatively. Although it was not possible to carry
out a statistical analysis due to the limited number of participants, the results demonstrate that there
is a difference in the gaze behaviour of drivers and riders, with the latter being far more focused on
the left-hand side of the road and concentrating on defined elements of road design. Furthermore, the
experiment demonstrated that a higher number of fixations is related to lower speeds. Finally, it was
noted that both kinds of road users focus fairly well on the carriageway, leading to the conclusion that
the indications given through road markings may be much more effective than vertical signalisation,
which has rarely been observed.

8. In-depth analysis of fatal motorcycle accidents—case study in SloveniaTomaž Tollazzi, Laura Brigita Parežnik, Chiara Gruden, Marko Renčelj, 2025, original scientific article Abstract: Motorcyclists remain a disproportionately large group of vulnerable road users, with fatality rates significantly higher than that in other road groups. Additionally, fatal accidents involving motorcyclists have a more slowly decreasing trend in comparison to that of other road users, while the number of this kind of users is growing fast. For all these reasons, there is a need to understand what the key factors leading to fatal accidents are in order to identify the possible measures to minimize the accidents themselves or at least their consequences. This would permit, indeed, to positively impact the road traffic system, leading to the creation of the safest road traffic system possible, as it is the goal of the Sustainable Safety approach. The aim of this study is to dive into the mentioned problem, analyzing fatal motorcycle accidents in Slovenia over a decade, highlighting the key factors contributing to these incidents. By integrating data from four databases, the study evaluated accident trends, infrastructural elements, and rider behavior through a multi-stage analysis. Firstly, data were collected from four national, up-to-date databases that contain information about road accidents themselves, the road infrastructure, additional police data, and media descriptions. After merging this information into one comprehensive database, where each row represents all the data available for one accident, a general analysis of accidents’ trends over the considered 10-year period was developed, considering at first all fatal road accidents, then deepening it to accidents caused by a motorcyclist, and finally to single-vehicle accidents. A statistical analysis followed, aimed at identifying a statistical correlation between the accidents and the factors leading to them. The results of the first accident analysis indicated that excessive speed, incorrect driving direction, and overtaking maneuvers are the primary causes of fatal accidents, especially on non-urban roads preferred by motorcyclists. Single-vehicle accidents frequently involve collisions with roadside objects, including safety barriers and poles, underscoring the need for targeted infrastructural improvements. The following correlation analysis revealed that a total of seven factors were statistically significant: three human factors (age, gender, experience)—which were the ones with the strongest correlations—one infrastructural factor (pavement width), and three factors belonging to external conditions (accident type, cause, and location). Of these, four were positively correlated to the causer, while three, i.e., pavement width, causes, and road location, were negatively correlated. This study provides a foundation for future research on less severe accidents and proactive risk behavior analysis, aiming to improve motorcyclist safety comprehensively.

9. The NASA-TLX approach to understand workers workload in humanrobot collaborationAljaž Javernik, Borut Buchmeister, Robert Ojsteršek, 2023, original scientific article Abstract: Human-robot collaboration (HRC) is becoming increasingly widespread in today's production systems, as it can contribute to achieving more efficient and flexible production systems. Given the growing importance of HRC, this paper addresses the significance of human workload in HRC. To study workers workload an experiment was conducted using NASA-TLX questionnaire. The experiment featured two scenarios involving the same operation but varying robot motion parameters. Recognizing that individual differences contribute to success of collaboration, the experiment considered worker utilization in relation to robot motion parameters. To ensure the credibility of the experimental results, the robot motion parameters were adjusted to each individual in order to achieve the same conditions and utilization at all participants. Results revealed that worker utilization, in conjunction with robot motion parameters significantly influenced worker workload. The results highlight the need for personalized guidelines in collaborative workplaces that emphasize individual differences in abilities, skills and personalities to increase overall well-being and robot and worker productivity.
