Weights refinement for the Active Ageing Index
No full textIn: Applications of mathematics and statistics in economics 2025 : book of abstracts. 1. vyd. Praha : Vysoká škola ekonomická, 2025. ISBN 978-80-245-2555-6. Pp. 16-16.The Active Ageing Index (AAI) is a composite measure designed to assess the potential of older individuals for active and healthy participation in society. It comprises 22 individual indicators, categorized into four domains. Each domain has a corresponding sub-index, calculated as a weighted mean of its indicators, while the overall AAI is determined as a weighted average of the four sub-indices. Initially, a panel of experts established the relative importance of the indicators and domains, expressed through implicit weights. To mitigate discrepancies arising from variations in indicator magnitudes, explicit weights were derived. Despite significant changes in some indicators over time, the explicit weights remained unchanged across all AAI editions for European countries. This prompted us to develop an optimization program to refine explicit weights based on current indicator data. The revised weights aim to minimize differences between individual indicators’ contributions to the AAI and expert recommendations. This approach can be applied at both national and subnational levels for more precise AAI calculations.VEGA 1/0124/24 Slovensko v kontexte dôchodkového indexu a indexu starnutia populácie - perspektíva budúcnost
Conceptualizations of inclusive schooling by pre-service teachers in Slovakia
No full textIn: Problems of education in the 21st century. Šiauliai : Scientia Socialis, 2025. ISSN 1822-7864. Vol. 83, no. 5 (2025), pp. 689-704.Understanding how pre-service teachers conceptualize inclusive schooling is critical for effective teacher education. The present study examined how 455 pre-service teachers from eight Slovak universities perceive and prioritize eight distinct conceptualizations of an inclusive school, analyzing influences of professional specialization, study mode, and experience with diversity. A quantitative survey, utilizing ratings on a 6-point Likert scale and forced choice ranking, revealed "every child is valued" as the most preferred concept, signaling a strong normative commitment to individual children's worth. "Bottom-up inclusion," emphasizing practical, team-based approaches, also ranked highly. While no significant differences were found across teacher specializations or personal experience with diversity, part-time students showed stronger preference for "bottom-up inclusion" compared to full-time students, who prioritized "every child is valued". These findings suggest that professional experience may shape more practical conceptualizations of inclusion, underscoring the importance of structured reflection alongside practical experience in teacher education.APVV-22-0450 Program rozvoja jazykových spôsobilostí detí s odlišným materinským jazykom v slovenskom jazyku - tvorba a overovani
Držanie tela u študentov múzických umení v závislosti od BMI indexu
No full textIn: Mladá veda = Young science. Prešov : Universum, 2025. ISSN 1339-3189. Roč. 13, č. 1 (2025), s. 1-10.Proper posture plays a crucial role in the lives of students in music and other artistic disciplines, as their activities often lead to static and asymmetrical postural positions, potentially contributing to the development of musculoskeletal disorders. This study aims to analyse posture and its individual segments in relation to Body Mass Index (BMI) among female students of performing arts. The research sample consisted of 107 female students from the Faculty of Performing Arts, divided into two groups based on BMI: students with optimal weight (BMI 18.5–24.99) and underweight students (BMI 0.05). Underweight students achieved a higher proportion of good to nearly perfect posture (57.58%) compared to students with optimal weight (33.78%). The findings highlight the necessity for an individualized approach to students based on their BMI and the implementation of targeted physical interventions to improve postural habits. Regular monitoring and educational activities can enhance the health and well-being of students in artistic disciplines, thereby promoting the achievement of optimal postural balance.VEGA 1/0512/24 Epidemiológia porúch muskuloskeletálneho systému u študentov múzických umen

Modern digital phenomena that disrupt the parent-child relationship
No full textIn: Disputationes scientificae Universitatis Catholicae in Ružomberok. Ružomberok : Verbum vydavateľstvo KU, 2025. ISSN 1335-9185. Roč. 25, č. 1 (2025), s. 21-32.The family should offer a place of unconditional love, knowledge, understanding and forgiveness that no one else provides. Family bonds and relationships are formed here. However, the large and easy availability of digital media and high Internet connectivity affects not only children, but also parents and families as a whole. Modern phenomena enter the parent-child relationship, which disrupt it. They are e.g. parental technoference, that is technological distraction, where a parent interrupts the interaction between him and his child to control a digital device, also includes parental phubbing, referring to the extent to which parents use or are distracted by their mobile phones while interacting with their children. Technoference is a term used to describe what people do when they "phub" someone around them. We will also focus on the phenomenon of sharenting, which is the sharing of information, photos and videos of children by their parents on the Internet. The development of technology brings more positives to humanity, but the biggest impact of negatives affects the family and its entire survival. That's why we want to point out the importance of digital minimalism in the post, through which the family strengthens its bonds and relationships.KEGA 024UMB-4/2022 Prevencia online rizikového správani

No full textIn: R&E-SOURCE. To the Roots: Engineering Pedagogy. Baden : Pädagogische Hochschule Niederösterreich, 2025. ISSN 2313-1640. Vol. 12, no. Sonderausgabe 1 (2025), pp. 75-89.This article focuses on the research-oriented model of student education in the subject of Technique in lower secondary education in the Slovak Republic. The proposed model reflects the long-term educational needs in the subject of Technique, which, despite updates to the curriculum in the Educational Standard of the subject, have yet to be fully addressed. The learning model includes worksheets for students that feature experiments, along with a methodology for carrying out each experiment. Students discover new knowledge through research activities during the experiment, which they then evaluate at the end of the worksheet. The worksheet also includes a self-assessment sheet, where students record their responses to the experiment, reflect on their understanding of the content, and assess their satisfaction with their performance.KEGA 006UMB-4/2022 Implementácia bádateľsky orientovaného modelu vzdelávania v predmete technika v nižšom strednom vzdelávaní so zameraním na kognitívnu oblasť
Fuzzy masks for correlation matrix pruning
No full textIn: IEEE Access. Piscataway : Institute of Electrical and Electronics Engineers, 2025. ISSN 2169-3536. Vol. 13 (2025), pp. 35387-35400.Among statistical methods used in data analysis processes, correlation analysis holds one of the most significant places. Using correlation, analysts measure prediction potential between values of a pair of attributes of a dataset which can be summarized into a correlation matrix for any multidimensional dataset. Such matrices are usually sizable, and hard to read. Pruning of the correlation matrix for the precise selection of attribute pairs of a considered dataset which bear strong prediction potential is conventionally conducted via correlation matrix masks. Since these masks are commonly designed as crisp borders for the acceptability of values in the matrix, there is a strong lack of nuance in this approach. The work presented in the scope of this study focuses on the design and implementation of fuzzy masks for correlation matrices.
This objective is divided into three main tasks - firstly, the visualization of correlation coefficient value frequency and its relationship to fuzzy membership function is designed and implemented, then visualisation of basic regression analysis and correlation context of attribute pairs in the fuzzy area of a studied dataset is designed and implemented, and lastly, the proposed approach is evaluated via case studies on three benchmarking datasets. The results obtained with the fuzzy approach to correlation matrix masks show a qualitative improvement in the matrix pruning task and a more appropriate identification of the relevant parts of the dataset compared to the conventional, crips approach
