1352. Effect of graded exercise therapy and medical care on chronic fatigue syndromeTamara Zličić, Darinka Korovljev, Tijana Šćepanović, Ivana Milovanović, 2023, pregledni znanstveni članek Povzetek: Purpose: Chronic Fatigue Syndrome (CFS) / Myalgic Encephalomyelitis (ME) is a complex condition with debilitating symptoms that significantly impact individuals, particularly those in the working population. This study aims to investigate the effec-tiveness of Graded Exercise Therapy (GET) and Cognitive Behavioral Therapy (CBT) along with additional methods such as Graded Exercise Self-help (GES), Adaptive Pac-ing Therapy (APT), and Specialist Medical Care (SMC), in managing Chronic Fatigue Syndrome (CFS) / Myalgic Encephalomyelitis (ME) among the working population. Methods: A systematic analysis of five randomized controlled trials conducted be-tween 2013 and 2023, encompassing GET, CBT, APT, SMC, and GES was performed using PubMed.Results: The selected studies consistently demonstrate that GET positively impacts physical functioning and reduces fatigue levels in working individuals with CFS. Ad-ditionally, CBT proves valuable, emphasizing the importance of addressing the mental aspects of CFS in occupational contexts.Conclusion: This review underscores the need for further research, advocating for direct assessment methods like biomarkers to enhance our understanding of CFS and improve treatment outcomes. These insights are crucial for healthcare practitioners, researchers, and policymakers navigating the complexities of CFS within the work-place. Emphasizing the integration of psychological interventions with physical therapies is essential for a comprehensive approach to managing CFS among the working population.

1354. The influence of physical activity on the arterial blood pressure of the elderly : a systematic reviewDoroteja Rančić, Tamara Ilić, Stefan Stojanović, 2023, pregledni znanstveni članek Povzetek: Purpose: The aim of this review was to determine the influence of physical activity on the arterial blood pressure of the elderly through a review of previous research.Methods: The search was performed on the Web of Science, Google Scholar and PubMed databases. The first search identified 1112 articles. In the initial assessment carried out in accordance with the inclusion and exclusion criteria, 15 articles were found suitable and were included in the study, while 1097 studies were excluded. The search was limited to articles published in period of 2002–2022.Results: After the applied exercise programs and evaluation at the final measure-ments, the mean values of systolic blood pressure, on the total sample, were 131 mmHg, while the values of diastolic blood pressure were 77 mmHg, which indicates that physi-cal activity (regardless of whether swimming, walking, yoga, resistance training, high interval training, Tai Chi) have a positive effect on the arterial blood pressure of the elderly.Conclusion: All studies, except one, showed a positive influence of physical activity on the arterial blood pressure of elderly people. In this regard, it can be concluded that physical activity, regardless of the type of activity, has a positive effect on the arterial blood pressure of the elderly, in the form of a reduction in blood pressure values.

1355. Why are the Early Gothic murals in St. Jacob’s Church in Ormož, Slovenia, almost entirely black?Anabelle Križnar, Katja Kavkler, Sabina Dolenec, 2024, izvirni znanstveni članek Povzetek: In St. Jacob’s parish church in Ormož, Slovenia, mural paintings from around 1350–1370 are partially conserved in the northeastern corner of the main nave. They are almost completely black, indicating a large-scale pigment degradation. They were studied as a part of a larger research project aiming to identify materials applied and their possible degradation. First, they were studied in situ, and next, extracted samples of plaster, pigments, and colour layers were analysed by optical microscopy, Raman spectroscopy, FTIR spectroscopy, SEM-EDS, and XRD. Haematite, green earth, malachite, azurite, and tenorite were identified, showing that azurite and perhaps also malachite degraded to black tenorite, probably due to their fine grinding and their application directly on the fresh plaster. The plaster is made with small and large amounts of aggregate with mostly quartz with some impurities, which makes it fragile. The original appearance of these murals was of bright blue and green colours.

1356. Foot posture index and hip joint rotation mobility in handball and soccer playersTjaž Brezovar, Matej Drobnič, Alan Kacin, 2023, izvirni znanstveni članek Povzetek: Purpose: To assess the foot posture and hip joint mobility of elite handball and soccer players and to investigate possible correlations between these measurements. Methods: We compared the differences in means of Foot Posture Index (FPI), pas-sive hip internal (IR), and external (ER) rotation range of motion (ROM) between three groups of male subjects (17 handball players, 17 soccer players, and 16 non-athletes). The Kruskal-Walli’s test and post-hoc pairwise comparison with the Mann-Whitney U test were used to determine the differences between the group means, and associations between variables were analyzed with Spearman’s correlation coefficient. Results: No significant differences in the mean FPI were found between the soccer players (1.3 ± 2.9), handball players (0.7 ± 2.1), and the control group (1.7 ± 2.5) (p > 0.05). Similarly, no significant difference was found between the groups in the hip ER ROM. In contrast, a significantly lower (p < 0.05) hip IR ROM was observed in the soccer players (30.6° ± 5.3°) compared to the handball players (41.0° ± 8.1°) and the control group (41.1° ± 6.4°). A weak positive correlation was only observed between the FPI and hip IR ROM in the soccer players (ρ: 0.36, p = 0.035). Conclusions: Handball and soccer players show a tendency toward less pronated feet compared to non-athletes, but the differences are not significant and the mean FPI values are still within the range of normal foot posture. The range of hip IR seems to be reduced in soccer players and weakly, but significantly and positively associated with the FPI value, which needs to be further investigated in future studies.

1357. Model uncertainty in a parametric fire curve approach : a stochastic correction factor for the compartment fire load densityFlorian Put, Andrea Lucherini, Bart Merci, Ruben Van Coile, 2024, izvirni znanstveni članek Povzetek: A commonly used approach to represent the thermal load in a compartment fire is the Eurocode Parametric Fire Curve (EPFC), which specifies gas temperatures (or rather adiabatic surface temperatures). Recognizing the significant deviations between real fires and the EPFC framework, the concept of model uncertainty is explored. This study does not aim to assess or improve the EPFC, but introduces a model uncertainty, allowing for reliability-based structural fire engineering (SFE). It presents a stochastic correction factor for the fire load density, based on the maximum temperature in steel sections. The focus is on the fire load density, but in general other parameters can be jointly taken into account as well. This correction factor considers protected and un- protected sections, incorporating variations in section factor and protection thickness. The findings reveal that the fire load density within the EPFC framework can be modified to better represent the severity of fire ex- periments. This approach ensures physical consistency of the obtained compartment gas temperatures, as opposed to alternative approaches for addressing the EPFC model uncertainty. While promising results are evident in this proof of concept, exploration for other types of structural elements and evaluation for structural systems is necessary before integration into design practices.

1358. Modelling intumescent coatings for the fire protection of structural systems : a reviewAndrea Lucherini, Donatella de Silva, 2024, pregledni znanstveni članek Povzetek: Purpose
Intumescent coatings are nowadays a dominant passive system used to protect structural materials in case of fire. Due to their reactive swelling behaviour, intumescent coatings are particularly complex materials to be modelled and predicted, which can be extremely useful especially for performance-based fire safety designs. In addition, many parameters influence their performance, and this challenges the definition and quantification of their material properties. Several approaches and models of various complexities are proposed in the literature, and they are reviewed and analysed in a critical literature review.
Design/methodology/approach
Analytical, finite-difference and finite-element methods for modelling intumescent coatings are compared, followed by the definition and quantification of the main physical, thermal, and optical properties of intumescent coatings: swelled thickness, thermal conductivity and resistance, density, specific heat capacity, and emissivity/absorptivity.
Findings
The study highlights the scarce consideration of key influencing factors on the material properties, and the tendency to simplify the problem into effective thermo-physical properties, such as effective thermal conductivity. As a conclusion, the literature review underlines the lack of homogenisation of modelling approaches and material properties, as well as the need for a universal modelling method that can generally simulate the performance of intumescent coatings, combine the large amount of published experimental data, and reliably produce fire-safe performance-based designs.
Research limitations/implications
Due to their limited applicability, high complexity and little comparability, the presented literature review does not focus on analysing and comparing different multi-component models, constituted of many model-specific input parameters. On the contrary, the presented literature review compares various approaches, models and thermo-physical properties which primarily focusses on solving the heat transfer problem through swelling intumescent systems.
Originality/value
The presented literature review analyses and discusses the various modelling approaches to describe and predict the behaviour of swelling intumescent coatings as fire protection for structural materials. Due to the vast variety of available commercial products and potential testing conditions, these data are rarely compared and combined to achieve an overall understanding on the response of intumescent coatings as fire protection measure. The study highlights the lack of information and homogenisation of various modelling approaches, and it underlines the research needs about several aspects related to the intumescent coating behaviour modelling, also providing some useful suggestions for future studies.
