81. Forward head posture in sports-involved childrenBoris Karasek, Miloš Kojić, Evelin Varga, Tijana Šćepanović, 2024, original scientific article Abstract: Purpose: Forward head posture (FHP) is the most common cervical postural fault in the sagittal plane that can cause various issues and conditions. The purpose of this study is to determine the prevalence of FHP among sports-involved children and to examine the differences in craniovertebral angle (CVA) with regard to gender, age, neck pain, and the sports in which they participate.Methods: A cross-sectional study was conducted among 154 sports-involved chil-dren (76 males and 78 females), aged 11–14, participating in various sports (basket-ball, football, volleyball, and athletics). After obtaining signed consent, photography of the sagittal view was performed in a standing position, which was then used to measure the CVA using the Web Plot Digitizer software. A questionnaire was used to gather data about gender, age, sports in which a participant is involved, presence of neck pain, and pain scale.Results: Among the 154 children, 37 (24.03%) exhibited FHP (15 males, 22 fema-les). The mean CVA for the entire sample was 51.30° ± 6.20°. Female participants had a significantly lower CVA (p = .021) compared to male participants. No significant differences were found with regard to age, presence of neck pain, or engagement in a specific sport.Conclusion: FHP is present in sports-involved children, with a higher prevalence among females

84. Evaluating basic motor competence in Italian children post-COVID-19 pandemic : iImplications for motor developmentDomenico Monacis, Dario Colella, Pierpaolo Limone, 2024, original scientific article Abstract: Motor competence assessment represents one of the most important topics in the field of motor development and physical education. The present cross-sectional study aims to assess basic motor competence, self-perception and enjoyment during physical activity (PA) in a sample of normal weight, and overweight or obese children post-COVID-19 pandemic. The participants (N = 107, age = 8-9 years old) were recruited from an experimental project conducted in Lecce (Italy). The motor competence assess-ment was undertaken using MOBAK 3-4 protocol, and self-perception and enjoyment were evaluated with two validated questionnaires. A multivariate analysis of variance (MANOVA) was performed to assess the effect of gender and BMI on the variables considered. Despite the MANOVA results indicating no significant interaction effects between variables, a significant main effect was found for gender [F(10,93) = 2.353, p = .013, η² = 0,218] and BMI cutoff [F(10,93) = 2.351, p = .013, η² = 0,218]. Moreover, an independent t-test highlighted significant differences in catching, dribbling, balanc-ing and object movement according to gender (p < .05), and in balancing, rolling and self-movement according to BMI cutoff (p < .05). Self-efficacy differed significantly be-tween males and females, while no significant effect was found for enjoyment. Further studies should investigate the effect of BMI and factors related to physical activity on motor competence development.

85. Evaluating physical outcomes in elderly sport and dance rollator users : a single-arm pilot study using lab-video-based dance intervention with a focus on integrating inter-communication technology in rollator danceNiharika Bandaru, Anita Hökelmann, Abdelaziz Triki, Ulrich Thiel, 2024, original scientific article Abstract: The present single-arm pilot study investigates the effects of a video-based dance intervention on physical outcomes in elderly individuals utilizing sports and dance rol-lators. In addition, the dance videos used in the current study are intended to integrate into the future Intercommunication Technology (ICT)-Rollator for the elderly. The aim is to evaluate the physical outcomes (such as gait, balance, mobility, and hand grip strength) during guided movement training (dance) using a video projected in a labora-tory setting. The pilot study involved six elderly rollator users (aged 85 and above). In the initial assessment, subjects were screened for mobility and coordination limitations prior to pre-testing using a four-square-step test and the SF-36 questionnaire. Both pre-testing and post-testing included assessments of mobility, balance, and spatiotem-poral gait parameters using the Timed Up-and-Go (TUG) test, Berg Balance Scale (BBS), and the Optogait system, respectively. Hand grip strength was measured using a hand dynamometer and reaction time was measured using a pipe-drop test. Blood pres-sure was monitored every 15 minutes during the training sessions to prevent adverse events, maintaining an upper range of 140-150/90-96. Adherence rates were measured based on the total duration of activity, calories burned per session, and dropout rates. Post-session questionnaires were administered to verify the respondents’ qualitative evaluations of their degrees of exhaustion, enjoyment, impediments, facilitators, and suggested changes. The intervention included heart rate monitoring, which revealed gradual and slight increases in heart rate intensity and gradual decreases in heart rate ranges (HRR) during the dance sessions. The results indicate improvements in balance, mobility, gait, and adherence rates. Future longitudinal research will further examine the effectiveness of the dance intervention using the ICT-Rollator, comparing it to a control group using a conventional rollator. The ICT-Rollator could be a unique rehabilitation aid for the elderly, offering promising improvements.

89. CFD-based analysis of deviations between thermocouple measurements and local gas temperatures during the cooling phase of compartment firesFlorian Put, Andrea Lucherini, Ruben Van Coile, Bart Merci, 2024, original scientific article Abstract: Data from thermocouple (TC) measurements play a pivotal role in fire safety science and engineering studies. It is well-known that there are deviations from the actual local gas temperature and many studies have led to the development of correction factors. The present study focuses on these deviations inside compartments through a systematic series of CFD simulations, performed with Fire Dynamics Simulator (FDS), version 6.8.0. A canonical cubic box is used as geometry. This allows for the demonstration of the impact of the presence of smoke, with variable optical thickness, on the TC data as retrieved from FDS. Significant differences are observed between TC measurements and local gas temperatures. Corrections as developed for TC measurements in open atmospheres cannot be readily applied in compartment configurations, where smoke properties change both spatially and temporally.

90. Odprta znanost in avtorske praviceAna Fidler, Mojca Žuželj, 2024, review article Abstract: Eno izmed temeljnih načel odprte znanosti je odprti dostop do rezultatov javno financiranih raziskav. Avtorji oz. imetniki avtorskih pravic zagotovijo odprti dostop med drugim z ustreznim upravljanjem avtorskih pravic. Krovni zakon, ki ureja avtorsko pravico v Sloveniji, je Zakon o avtorski in sorodnih pravicah, ki je bil nazadnje spremenjen septembra 2022. Z novelo smo v slovenski pravni red dobili za področje odprte znanosti pomembni izjemi, in sicer izjemo za besedilno in podatkovno rudarjenje za namene znanstvenega raziskovanja ter splošno izjemo za znanstveno raziskovanje. Novembra 2021 je bil sprejet Zakon o znanstvenoraziskovalni in inovacijski dejavnosti ter maja 2023 Uredba o izvajanju znanstvenoraziskovalnega dela v skladu z načeli odprte znanosti, ki podrobneje določata zagotovitev odprtega dostopa do vseh recenziranih znanstvenih objav in raziskovalnih podatkov ter drugih rezultatov, pridobljenih v okviru raziskav, sofinanciranih z javnimi viri najmanj v višini 50 %. V članku bomo podrobneje opisali zakonodajno ureditev avtorskih pravic v Sloveniji in spremembe na zakonodajnem področju, ki so povezane z odprto znanostjo. Predstavili bomo licence Creative Commons, ki so svetovno znane in pomembne za boljšo dostopnost rezultatov raziskav, širjenje znanja ter kakovost izobraževanja. Dalje bomo predstavili strategijo ohranjanja pravic in pravico do sekundarnega publiciranja kot ukrepa oz. pobudi, ki sta bili razviti za spodbujanje dostopa do publikacij in njihove ponovne uporabe ter odpravljanje omejitev, ki jih za raziskave predstavlja avtorskopravna zakonodaja.
