THE IMPACT OF HEALTHY LIFESTYLE APPS' QUALITY ON SATISFACTION AND PERCEIVED IMPACT USING PLS SEM

Ida Ercsey Veronika Keller

Publication Name: Vezetestudomany

Publication Date: 2025-01-01

Volume: 56

Issue: 5

Page Range: 57-71

Description:

Lifestyle and wellbeing (LS) apps represent a popular form of m-health apps that facilitate the maintenance and improvement of health by encouraging active lifestyles. This study aims to adapt the uMARS scale, developed for evaluating the quality of m-health applications, and to investigate the relationship between quality, satisfaction, and behaviour factors in LS applications. Data collection was conducted using a survey in autumn 2023, with a sample size of 157 respondents. The PLS-SEM method was employed to test the hypotheses. The results indicate that four qualitative dimensions of LS apps have a direct impact on overall satisfaction. The qualitative dimensions of LS apps, including functionality, information content and aesthetics, directly impact users’ perceived health-related knowledge, attitudes and behaviour. Furthermore, the quality dimensions indirectly influence users’ perceived health-related factors through satisfaction.

Description:

Background: Beam walking is a new test to estimate dynamic balance. We characterized dynamic balance measured by the distance walked on beams of different widths in five age groups of healthy adults (20, 30, 40, 50, 60 years) and individuals with neurological conditions (i.e., Parkinson, multiple sclerosis, stroke, age: 66.9 years) and determined if beam walking distance predicted prospective falls over 12 months. Methods: Individuals with (n = 97) and without neurological conditions (n = 99, healthy adults, age 20–60) participated in this prospective longitudinal study. Falls analyses over 12 months were conducted. The summed distance walked under single (walking only) and dual-task conditions (walking and serial subtraction by 7 between 300 to 900) on three beams (4, 8, and 12-cm wide) was used in the analyses. Additional functional tests comprised grip strength and the Short Physical Performance Battery. Results: Beam walking distance was unaffected on the 12-cm-wide beam in the healthy adult groups. The distance walked on the 8-cm-wide beam decreased by 0.34 m in the 20-year-old group. This reduction was ~ 3 × greater, 1.1 m, in the 60-year-old group. In patients, beam walking distances decreased sharply by 0.8 m on the 8 versus 12 cm beam and by additional 1.6 m on the 4 versus 8 cm beam. Beam walking distance under single and dual-task conditions was linearly but weakly associated with age (R2 = 0.21 for single task, R2 = 0.27 for dual-task). Age, disease, and beam width affected distance walked on the beam. Beam walking distance predicted future falls in the combined population of healthy adults and patients with neurological conditions. Based on receiver operating characteristic curve analyses using data from the entire study population, walking ~ 8.0 of the 12 m maximum on low-lying beams predicted future fallers with reasonable accuracy. Conclusion: Balance beam walking is a new but worthwhile measure of dynamic balance to predict falls in the combined population of healthy adults and patients with neurological conditions. Future studies are needed to evaluate the predictive capability of beam walking separately in more homogenous populations. Clinical Trial Registration Number NCT03532984.

Knowledge management strategy as a chance of small and medium-sized enterprises

Andrea Bencsik Timea Juhász

Publication Name: International Business Strategy and Entrepreneurship an Information Technology Perspective

Publication Date: 2013-11-30

Volume: Unknown

Issue: Unknown

Page Range: 52-81

Description:

This chapter shows how SMEs can compete with multinational companies. This chapter was written on the basis of practical research results. In this research, Hungarian and Slovakian SMEs were investigated from the view of a Knowledge-Based economy. The question was how they can face future challenges. The researchers wanted to know how SMEs handle their chance which is hidden in their way of thinking about a knowledge strategy. As a result, these companies seem to be afraid, uncertain, and think their success is only luck or a current incident. They live a 'fly by night' existence, and they do not feel the importance of development, of studying, of knowledge; they run after work and money. These enterprises feel that they have to survive, and to this, they need money and financial capital. Therefore, knowledge and studying fall behind.

Where Do Pedestrians Look, When Crossing Suburban Railway Lines with Right- and Left-Hand Traffic?

Gabriella Kosztolányi-Iván Csaba Koren Bayasgalan Nemekh

Publication Name: Lecture Notes in Networks and Systems

Publication Date: 2025-01-01

Volume: 1258 LNNS

Issue: Unknown

Page Range: 107-119

Description:

We have learned from childhood on, that before crossing a street, first we must look left, then to right. This is related with the right-hand traffic system of cars. The research question in this paper is: how we behave in an unfamiliar situation, when crossing left-hand traffic. In Budapest, four of the five suburban railway lines operate with right-hand traffic, but one of them works in the left-hand system. The aim of this article is to investigate the behavior of pedestrians in level crossings with right- and left-hand railway traffic and to reveal any differences between their behavior, as well as the safety of these lines. The main findings are that pedestrians look at the “built-in” left-right order, even it is not the safest option. Parallelly, accident data show worse safety situation of the line with left-hand traffic. As conclusion, some low-cost infrastructure measures are recommended.

Airflow Resistivity Measurements of Acoustic Poroelastic Materials and their Influencing Factors

Daniel Feszty Balázs Vehovszky Attila Schweighardt

Publication Name: Manufacturing Technology

Publication Date: 2025-01-01

Volume: 25

Issue: 5

Page Range: 678-688

Description:

In the automotive sector, poroelastic materials (PEMs) are used as trim elements to achieve the desired interior acoustics of a vehicle. This study examines the effect of manufacturing as well as measurement techniques on airflow resistivity. This property plays a key role in the acoustic behavior of PEMs. First, the importance of engineering acoustics and poroelastic materials in vehicle industry is reviewed, followed by the introduction of the most important properties and their measurement techniques. Next, the theory and the measurement techniques used to determine resistivity via direct method are detailed. Then the factors influencing the results and their quantified effects are presented. More than 10 influencing factors are identified and examined, from which the inhomogeneity, resulting from the production technology proved to be the most significant. The results obtained with direct and inverse methods are compared for validation purposes and to determine the achievable accuracy of the inverse method. The average difference between the two methods is 4.54%, which means that the inverse method can provide a good approximation. Finally, conclusions are drawn and suggestions are made for the future.

Publication Name: Periodica Polytechnica Transportation Engineering

Publication Date: 2025-01-01

Volume: 53

Issue: 3

Page Range: 301-307

Description:

In both the European Union Member States and Hungary, a large number of people are killed in road traffic accidents. Reducing road collisions, personal injuries, and fatalities is a priority. To get an accurate picture of the situation, it is necessary to know the accident statistics of the European Union and the main EU directives that define a Safe Transport System. We then review the road safety situation in Hungary, using data from 2017 to 2020. In preparing the statistical overview, particular attention will be paid to the spatial distribution of severity, over time and by county, the distribution of accident participants by type of transport, the characteristics of the persons involved in the accident, the causes of the accidents and the distribution by type of accident. The analysis includes an explanation of the variables related to the vehicles involved in the accident and the causes of accidents related to human factors.

Systematic Literature Review on Overspending and Sustainable Budgeting: Insights for Hungarian Households

Boglárka Eisingerné Balassa Tímea Vastag

Publication Name: Sustainability Switzerland

Publication Date: 2024-11-01

Volume: 16

Issue: 21

Page Range: Unknown

Description:

This study overviews the keywords overspending, family, and sustainable budget from different perspectives in the existing literature. Its goal is to identify the gap through keyword analysis and formulate a methodological direction for the future, using an overview of the methodologies used for researching individual keywords. This publication is based on a systematic literature review, including articles from the Web of Science, Science Direct, and Scopus databases. The resulting publications are analyzed from several angles, such as the number of publications per keyword per year, which methodologies were applied, and at which level (micro, meso, macro) the topic was previously researched. As an output of the partial analyses, both the lack of research on the sustainable spending habits of Hungarian households and the need for a methodology that can be applied for this purpose emerges. The results enable the development of a combined method, with which current research can be carried out on a micro level regarding sustainable spending habits in Hungary.

A study on solving single stage batch process scheduling problems with an evolutionary algorithm featuring bacterial mutations

Miklos Ferenc Hatwagner Máté Hegyháti Olivér Ősz

Publication Name: Lecture Notes in Computer Science Including Subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics

Publication Date: 2018-01-01

Volume: 10841 LNAI

Issue: Unknown

Page Range: 386-394

Description:

The short term scheduling of batch processes is an active research field of chemical engineering, that has been addressed by many different techniques over the last decades. These approaches, however, are unable to solve long-term scheduling problems due their size, and the vast number of discrete decisions they entail. Evolutionary algorithms already proved to be efficient for some classes of large scheduling problems, and recently, the utilization of bacterial mutations has shown promising results on other fields. In this paper, an evolutionary algorithm featuring bacterial mutation is introduced to solve a case study of a single stage product scheduling problem. The solution performance of the algorithm was compared to a method from the literature. The results indicate that the proposed approach can find the optimal solution under relatively short execution times.
