131. Liu Hai draži zlato krastačo : srečenosni motivi na lesenem stojalu za ogledalo iz Skuškove zbirkeNataša Vampelj Suhadolnik, 2022, original scientific article Abstract: Članek analizira srečenosno motiviko na lesenem stojalu za ogledalo iz Skuškove zbirke, ki ga hrani Slovenski etnografski muzej. Srečenosno motiviko postavi v širši kontekst kitajskih kulturnih in jezikovnih struktur, ki je v vizualni reprezentaciji kombiniranih motivov rastlin, živali in oseb omogočil nešteto kombinacij rebusov in preigravanja z enakozvočnicami. Ti so temeljili na kitajski zgodovinski, literarni, filozofski, religiozni in mitološki tradiciji. Srečenosni motivi so v kitajskem kulturnem kontekstu postali standardna shema okraševanja, iz katere so črpali tako slikarji učenjaki kot obrtniki, njihovo upodabljanje pa se je razširilo tudi zunaj kitajskih meja. Še posebej razširjeni postanejo na vsakdanjih predmetih, ki uporabnikom ne le izrekajo dobre želje za srečo, bogastvo, napredovanje, dolgoživost in potomstvo, temveč sočasno zagotavljajo njihovo uresničitev. To je vidno tudi na lesenem stojalu za ogledalo, ki ga je med letoma 1914 in 1920 v Pekingu kupil mornariški častnik Ivan Skušek ml. Članek v prvem delu prikaže ikonografsko analizo motivike, v drugem pa so podrobneje obravnavana zajeta sporočila v vizualnih simbolnih kodah, pri čemer so upoštevani tudi razporeditev motivike v zaključeno zgodbo in načini interpretiranja teh podob.

133. Exploring the well-being of Slovenian and Serbian sport science students during the covid-19 pandemic of summer 2022Brigita Banjac, Ivana Milovanović, Saša Pišot, Radenko Matić, Stevo Popović, Sandra Radenović, Patrik Drid, 2023, original scientific article Abstract: The COVID-19 pandemic profoundly changed everyday life of social actors, which inferred mental health and well-being concerns. As students of health-related studies tend to adapt better to difficult circumstances, in this study, we explored the effect of the pandemic on sports science students’ well-being during the summer of 2022. The research was conducted in Slovenia and Serbia. The sample comprised n = 350 students. The PERMA-Profiler, a 15-item self-reported questionnaire, was adapted to assess well-being across five elements: positive emotions, engagement, relationships, meaning, and accomplishment. Data were collected with a questionnaire through the summer of 2022 (from May to July) and analyzed in SPSS, AMOS 26.0. The results revealed normal functioning (M = 7.72, SD ± 1.38) for the overall well-being of the students. Although all dimensions indicated high scores, relationships (M = 7.95, SD ± 1.63), meaning (M = 7.76, SD ± 1.69), and engagement (M = 7.73, SD ± 1.36) rated the highest. Furthermore, the instrument was acceptable, as the confirmatory factor analysis showed adequate reliability based on Cronbach's alpha (15 items, α = 0.94) and strong internal correlations between the PERMA dimensions. This study contributes to the previously published research, emphasizing the positive responses and successful coping of sports science students in times of complex situations, such as the COVID-19 pandemic.

134. On the influence of aging on classification performance in the visual EEG oddball paradigm using statistical and temporal featuresNina Omejc, Manca Peskar, Aleksandar Miladinović, Voyko Kavcic, Sašo Džeroski, Uroš Marušič, 2023, original scientific article Abstract: The utilization of a non-invasive electroencephalogram (EEG) as an input sensor is a common approach in the field of the brain–computer interfaces (BCI). However, the collected EEG data pose many challenges, one of which may be the age-related variability of event-related potentials (ERPs), which are often used as primary EEG BCI signal features. To assess the potential effects of aging, a sample of 27 young and 43 older healthy individuals participated in a visual oddball study, in which they passively viewed frequent stimuli among randomly occurring rare stimuli while being recorded with a 32-channel EEG set. Two types of EEG datasets were created to train the classifiers, one consisting of amplitude and spectral features in time and another with extracted time-independent statistical ERP features. Among the nine classifiers tested, linear classifiers performed best. Furthermore, we show that classification performance differs between dataset types. When temporal features were used, maximum individuals’ performance scores were higher, had lower variance, and were less affected overall by within-class differences such as age. Finally, we found that the effect of aging on classification performance depends on the classifier and its internal feature ranking. Accordingly, performance will differ if the model favors features with large within-class differences. With this in mind, care must be taken in feature extraction and selection to find the correct features and consequently avoid potential age-related performance degradation in practice.

135. Does standing up enhance performance on the stroop task in healthy young adults? : a systematic review and meta-analysisMaja Maša Šömen, Manca Peskar, Bettina Wollesen, Klaus Gramann, Uroš Marušič, 2023, review article Abstract: Understanding the changes in cognitive processing that accompany changes in posture can expand our understanding of embodied cognition and open new avenues for applications in (neuro)ergonomics. Recent studies have challenged the question of whether standing up alters cognitive performance. An electronic database search for randomized controlled trials was performed using Academic Search Complete, CINAHL Ultimate, MEDLINE, PubMed, and Web of Science following PRISMA guidelines, PICOS framework, and standard quality assessment criteria (SQAC). We pooled data from a total of 603 healthy young adults for incongruent and 578 for congruent stimuli and Stroop effect (mean age = 24 years). Using random-effects results, no difference was found between sitting and standing for the Stroop effect (Hedges’ g = 0.13, 95% CI = −0.04 to 0.29, p = 0.134), even when comparing congruent (Hedges’ g = 0.10; 95% CI: −0.132 to 0.339; Z = 0.86; p = 0.389) and incongruent (Hedges’ g = 0.18; 95% CI: −0.072 to 0.422; Z = 1.39; p = 0.164) stimuli separately. Importantly, these results imply that changing from a seated to a standing posture in healthy young adults is unlikely to have detrimental effects on selective attention and cognitive control. To gain a full understanding of this phenomenon, further research should examine this effect in a population of healthy older adults, as well as in a population with pathology.

136. How do you feel at school? : a cross-country comparative analysis of migrant adolescents' school well-beingLucija Dežan, Mateja Sedmak, 2023, original scientific article Abstract: Adolescents present a relevant stakeholder in international migrations since they comprise a large share of all migrants. Previous studies show that migration processes significantly affect the well-being of migrant adolescents. This article investigates how the school environment, with its pedagogical practices and interpersonal relationships established between migrant adolescents, their classmates, and teachers, affect migrant adolescents’ well-being. Our research draws on quantitative data collected as part of the MiCREATE project. The sample of migrant adolescents (N = 700) was surveyed in 46 schools in six countries: Austria, Denmark, Slovenia, Spain, Poland, and the United Kingdom. Results indicate that migrant adolescents like school and feel safe there, however, they tend to be more satisfied with relationships established with teachers than with peers. Furthermore, differences in self-perceived school well-being emerge when comparing countries with a longer tradition of high migration flows (Spain, Denmark, and the United Kingdom) and those less experienced (Poland and Slovenia), although slight exceptions were detected. The results lead to the conclusion that schools that foster intercultural education and fulfilling interpersonal relationships are essential for school well-being of migrant adolescents and present an important step toward successful integration of migrant youth.

137. Prediction of actual from climatic precipitation with data collected from northern Poland : a statistical approachJacek Barańczuk, Martina Zeleňáková, Hany F. Abd-Elhamid, Katarzyna Barańczuk, Salem S. Gharbia, Peter Blišťan, Cécil J. W. Meulenberg, Peter Kumer, Włodzimierz Golus, Maciej Markowski, 2023, original scientific article Abstract: Water is a basic element of the natural environment and the most important component in human water management. Rainfall is the main source of water. Therefore, determining the amount of precipitation reaching the ground using sensors is crucial information. Precise precipitation data are necessary for better modeling quality, as the observation data from weather stations are used as basics for weather model assessment. The authors compared precipitation from the Hellmann rain gauge (climatic precipitation, 1.0 m above the ground surface) measured throughout the year and the GGI 3000 rain gauge (actual precipitation on the ground level) measured from April to October. Measurement sequences from the years 2011–2020 were considered. The data for analysis were obtained from a weather station located in northern Poland. The authors analyzed the relationships between data from the two sensors. A comparative study showed that the measurements of actual precipitation are higher and there are strong relationships between actual and climatic rainfall (r = 0.99). Using the introduced coefficient it is possible to determine the full–year actual precipitation with high probability, taking into account the precipitation with a correction from the winter half-year and the actual precipitation from the summer half-year, which is of great importance in the calculation of the water balance.

140. Combining physical and virtual worlds for motor-cognitive training interventions : position paper with guidelines on technology classification in movement-related researchLuka Šlosar, Claudia Voelcker-Rehage, Armin Paravlić, Ensar Abazović, Eling D. de Bruin, Uroš Marušič, 2022, review article Abstract: Efficient movements require intact motor and cognitive function. There is a growing literature on motor-cognitive interventions to improve the overall quality of life of healthy or diseased older people. For such interventions, novel technological advances are crucial not only in terms of motivation but also to improve the user experience in a multi-stimuli world, usually offered as a mixture of real and virtual environments. This article provides a classification system for movement-related research dealing with motor-cognitive interventions performed in different extents of a virtual environment. The classification is divided into three categories: (a) type of digital device with the associated degree of immersiveness provided; (b) presence or absence of a human-computer interaction; and (c) activity engagement during training, defined by activity >1.5 Metabolic Equivalent of task. Since virtual reality (VR) often categorizes different technologies under the same term, we propose a taxonomy of digital devices ranging from computer monitors and projectors to head-mounted VR technology. All immersive technologies that have developed rapidly in recent years are grouped under the umbrella term Extended Reality (XR). These include augmented reality (AR), mixed reality (MR), and VR, as well as all technologies that have yet to be developed. This technology has potential not only for gaming and entertainment, but also for research, motor-cognitive training programs, rehabilitation, telemedicine, etc. This position paper provides definitions, recommendations, and guidelines for future movement-related interventions based on digital devices, human-computer interactions, and physical engagement to use terms more consistently and contribute to a clearer understanding of their implications.
