Description:

Background: Although it is widely recognized that more attention needs to be paid to children's fluid intake, there is little information on how to improve it. Peer education has been suggested as an effective approach to changing health behaviors among school children. As a new approach, our study piloted a peer education program to improve children's fluid intake in primary schools. Methods: University students were prepared for their role as peer educators in an elective university course, including the concept of peer education and different pedagogical methods. The peer educators evaluated the training process by completing a questionnaire. The intervention took place during a School Health Day led by the peer educators. An anonymous survey with a questionnaire on knowledge of fluid intake was administered two weeks before, at the end of, and 15 weeks after the intervention. Changes in hydration knowledge were tested using repeated measures ANOVA. Results: The pilot program showed increased knowledge about fluid consumption (p < 0.001) in lower and upper primary school children (N = 326) at the end of the School Health Day compared to pre-intervention measures. A positive change was observed after 15 weeks only in upper primary students. Feedback from peer educators was useful for fine-tuning the program. Conclusions: This innovative program induced positive changes in knowledge about fluid intake in primary school children. The persistence of the changes differed between lower and upper primary school children. Based on the results, the intervention should be replicated to adapt the program to the needs of lower primary school children. Because the training of peer educators and the peer education program appeared to be successful, this program is worthy of international replication. This approach may also be suggested for other behavior change issues.

THE IMPACT OF COVID-19 AND THE RUSSIAN-UKRAINIAN CONFLICT ON THE ORGANISATIONS STUDIED

Publication Name: Vezetestudomany

Publication Date: 2024-03-14

Volume: 55

Issue: 3

Page Range: 14-28

Description:

In the last three years, the way the world works has changed more than in all the previous decades combined. The changes in market processes and systems have clearly been driven by two dominant phenomena: the pandemic crisis caused by COVID-19 and the Russian-Ukrainian conflict. These two world events have changed fundamental norms, which has forced organisations to change their strategies. The question is: what are the organisations in question really planning? What is influencing their reactions? The aim of the authors’ publication is to show how organisations were thinking in the early stages of the two crises, and whether they are able to assess the expected impact and plan the appropriate measures. Their empirical research found that micro-enterprises tend to project their pessimism on the whole economy. Also, their services are less dependent on supply chain resilience. Furthermore, their various war-induced measures were related to their past external relations.

ATTITUDES TOWARDS END-OF-LIFE DECISIONS AMONG NEONATOLOGY INTENSIVE CARE WORKERS - LEGAL ASPECTS BEHIND DECISIONS

Publication Name: Lege Artis Medicinae

Publication Date: 2022-01-01

Volume: 6

Issue: 7

Page Range: 289-297

Description:

Introduction - Minors' end-of-life dilemmas are among the most difficult decisions. Premature infants' chance of survival has greatly improved thanks to the development of technology. Under-age children's quality of life, as an aspect, does not appear in the effective Hungarian legislation. The aim of our study is to survey the change in NICU (neonatology intensive care unit) workers' opinions/attitudes after a 20-year-period about restrictions in severely impaired new-borns' intensive cares. Methods - Quantitative, complete sociological surveys in the Hungarian NICUs using self-administered, anonymous questionnaires (n = 728). Cross-Tabulation analysis and Pearson chi-squared test have been used for the data evaluation. Results - In both studies, the majority of participants agreed that if the condition is fatal, it may be appropriate to limit the intensive care. Acceptance of treatment withdrawal has increased, but active euthanasia is still not accepted. Most healthcare workers are unsatisfied with the current legal order and there is a need for change, especially in cases of fatal and poor prognosis. Conclusion - Despite the fact that the effective Hungarian health care regulation does not allow withdrawal of treatment even in severe conditions, a significant number of those working at Hungarian NICUs would consider it as acceptable in some cases, moreover the share of acceptance has in - creased in the last two decades. Comparing the results with the current regulations, it can be suggested that it is necessary to increase the sensitivity of the legislators and to change the related legislation.

Measurement distortion analysis of repetitive and isolated track geometry irregularities

Publication Name: Periodica Polytechnica Civil Engineering

Publication Date: 2021-07-13

Volume: 65

Issue: 3

Page Range: 852-865

Description:

Track geometry measurements are essential for day-to-day activities of railway maintenance and play an important role in vehicle-track simulations. The generally applied forms of longitudinal level and alignment recordings do not reflect the real shape of the track. Both the versine measurement method and the band-pass filters according to European regulation cause significant amplitude modification and pattern change. In addition, the distortion behavior of repetitive and isolated defects is fundamentally different. In this contribution, simulated measurements of various reference shapes, which represent repetitive and isolated track deformations, were investigated. Comprehensive functions for amplitude change and for other distortion factors were developed with analytical and numerical methods. For chord measurements, rules were found for zero points and distortion-free ranges. Regarding the standardized filters, a significant amplitude reduction of isolated defects was observed in all wavelength ranges. Since derailment and track degradation depend not only on the amplitude of the defect, also the derivatives of the original and filtered forms of reference shapes were investigated and, as a new approach, the defect features called 'hypothetical additional force', 'speed of hypothetical wheel lift-off', 'hypothetical deterioration impulse' and 'hypothetical deterioration energy' were introduced.

The Role of Robotics in Digital Education: A Steam-Based Approach for Curriculum Development

Publication Name: Saci IEEE International Symposium on Applied Computational Intelligence and Informatics

Publication Date: 2025-01-01

Volume: Unknown

Issue: 2025

Page Range: 605-608

Description:

The integration of robotics and artificial intelligence (AI) into education has become increasingly significant as digital technology evolves. This paper explores the historical development and current trends in digital culture education, emphasizing the need for a STEAM-based (Science, Technology, Engineering, Arts, Mathematics) approach. The study argues that the inclusion of robotics in education does not necessitate the introduction of new subjects but rather an adaptation of existing methodologies. We propose a structured framework for integrating robotics into current educational curricula, emphasizing interdisciplinary learning and problemsolving skills. The conclusions suggest that moving beyond traditional subject boundaries can foster a more holistic and effective learning environment.

Numerical investigation on flexural buckling behavior of hot-rolled steel columns at elevated temperatures

Publication Name: Periodica Polytechnica Civil Engineering

Publication Date: 2021-07-13

Volume: 65

Issue: 3

Page Range: 918-927

Description:

In this paper, a numerical investigation on the global buckling capacity of the axially compressed steel columns with hot-rolled I cross-section at elevated temperatures is presented. Geometrically and materially non-linear finite element model and the ABAQUS software were used to determine the buckling resistance. The numerical ABAQUS model was validated using experimental results available in the literature, and then the validated numerical model was used to generate a database of load-carrying capacity. The parametric study covered three different cross-section classes (class 1, 2 and 3), ten different non-dimensional slenderness ̄λ = 0.5, 0.6, 0.7, 0.9, 1.1, 1.3, 1.5, 1.7, 1.9, 2.0), three different temperatures (400°C, 500°C, 600°C), and two stress-strain constitutive relations including (the nonlinear material model adopted in the European guidance for structural fire design EN1993-1-2, and a Bilinear material model), with and without residual stress. The influence of the model parameters on the load capacity of steel columns at elevated temperatures was evaluated. The results of the parametric study were compared with the results of the simplified calculation model presented in EN1993-1-2.

Fingerprint Revolution: Unleashing the Potential of Modified Bacterial Memetic Evolution for a Paradigm Shift in Fingerprint Recognition and Optimization

Publication Name: Studies in Computational Intelligence

Publication Date: 2026-01-01

Volume: 1222

Issue: Unknown

Page Range: 115-123

Description:

Biometrics refers to the science of measuring and analyzing biological or behavioral characteristics to identify people. It has been used in many fields including digital forensics, identification systems, and security. The most common biometric nowadays is fingerprint, which has improved significantly in the last two decades. Several issues in fingerprint identification and authentication systems have been raised due to factors such as displacement of the finger while scanning, fingerprint rotation, major cuts, distortions, and substandard quality images lowering the overall system efficiency. Evolutionary algorithms evolved in recent years to enhance the system performance over time. The proposed system uses a modified version of the bacterial memetic evolutionary algorithm to overcome the identification issues and to help and support forensic experts to make reliable decisions faster. The proposed system was evaluated on five different databases and the results demonstrated that the system succeeded in identifying the correct match from the first candidate in all cases among all examined databases.
