Description:

Strokes are one of the leading causes of adult disability. There are a wide range of therapies available in stroke care for people with stroke, but there can be wide variations in the effectiveness of these therapies, so it is essential to review and compare them from time to time. In our study, we measured and compared the effectiveness of three high-intensity therapies: an agility training program without technological tools, a virtual reality exergaming training program with a low-cost device, and a high-cost robotic training program using augmented and virtual reality. All three therapies helped to improve the patients’ functional abilities, balance, and gait. On average, endurance increased by 104–177%, balance scores by 36–53%, and gait speed by 5–10% depending on the intervention. Robotic therapy and exergaming facilitate greater improvements in walking speed, step length, and balance-related gait metrics. These findings have profound implications for stroke rehabilitation, advocating for the prioritization of robotic and exergaming interventions over conventional functional therapies, like agility training. Given the limited sample size, the results should be interpreted as preliminary, highlighting the need for further studies with larger cohorts.

Description:

The condition of the lubricating oil is a critical factor for the lifetime of internal combustion engines. The timing chain is a particularly sensitive component to the oil quality, so it can be used as an indicator when the effect of the oil quality and contamination on the engine has to be examined. For this purpose, a unique timing chain test bench was developed at the Department of Propulsion Technology at Széchenyi István University. This paper presents the function of this test equipment and the results of the first tests aimed at comparing the wear of a diesel engine’s timing chain using various soot-contaminated engine oils. A significant difference in wear was detected after 25 h of operation using oils with different soot contents. In the case of oil comparison studies, the chain test bench can be a cheap and fast alternative to engine dynamometer tests.

Evaluation of a CUSUM-Type Changepoint Detector Applied in the Time-Frequency Domain of Synthetic Road Vehicle Vibrations

Péter Földesi László Róbert Hári

Publication Name: Lecture Notes in Mechanical Engineering

Publication Date: 2023-01-01

Volume: Unknown

Issue: Unknown

Page Range: 812-823

Description:

Non-stationary random vibrations gained increasing interest in vibration testing. Often, a changepoint detection procedure handles the decomposition of Road vehicle vibrations (RVV) when analysing the recorded series. Unfortunately, only subjective justifications support the proposed methods, and mainly the validation of the non-stationarity of simulated signals is concerned. Thus, if a detector is inherent to the procedure, it is also recommended to calibrate it. The current paper concerns the Receiver operating characteristics (ROC) of a CUSUM-type algorithm and supplies contextual support by Segment length distributions (SLD).

Evaluating the effectiveness of public finance used for social protection of internally displaced persons

Yuriy Bilan Halyna Mishchuk Natalia Samoliuk Halyna Yurchyk

Publication Name: Public and Municipal Finance

Publication Date: 2025-01-01

Volume: 14

Issue: 1

Page Range: 23-40

Description:

The increasing number of internally displaced persons (IDPs) in wartime Ukraine leads to growing problems in social protection funding. Under these circumstances, the evaluation of the effectiveness of public finance use is of increasing importance. The study aims to evaluate the effectiveness of public finance for internally displaced persons’ social protection, adapting the KPI methodology for analysis on the national level. The effectiveness is considered following the OECD approach as the extent to which the intervention achieved its objectives and results. At macrolevel of research, the integral indicator was developed based on indicators of input (financing of social protection programs), output (involvement of IDPs in social programs), activity (funding per recipient and multiplicative effect in GDP growth), mechanism (administrative costs for achieving results), and control (effectiveness of IDPs’ social protection compared to other demographic groups). Thirty indicators in total were used (e.g., budgetary funding allocated for housing assistance; budget expenditures on staff salaries of the authorities responsible for certain programs; coverage rate of unemployed IDPs receiving vocational training). The essential distance from the maximum level of expected results (1.0) allows concluding the low effectiveness in this area of public finance use: from 0.330 in 2020 to 0.668 in 2023. Gaps are evident in each direction, especially in input performance (the highest value did not exceed 0.370). The best results were achieved in housing funding and employment governance. The proposed approach is useful for analyzing gaps and identifying opportunities to improve the management of other social programs.

Description:

Research background: Tourism plays a central role in global economic development and cross-cultural exchange. In the wake of the COVID-19 pandemic, there has been a growing focus on integrating sustainability, innovation, and equity into tourism practices. Traditional models have often overlooked the complex interplay of social, environmental, and economic challenges faced by destinations. This has spurred a rethinking of tourism development, driven by community empowerment, climate concerns, and technological advances. Purpose of the article: The study aims to explore how a transformative approach to tourism can be achieved by centering community participation, embracing sustainability, and incorporating innovative social practices. It focuses on the intersections of social innovation, ruralluxury travel, heritage preservation, and inclusive governance. The authors seek to construct a conceptual framework that captures emerging themes and sub-themes within sustainable tourism, offering practical insights for policymakers and industry stakeholders. Methods: An integrative review approach was applied, guided by PRISMA methodology. Following keyword extraction, topic modeling was conducted using Latent Dirichlet Allocation (LDA), a widely used technique for discovering hidden topics in text data. Over 12,000 academic sources from the Scopus database were synthesized. A conceptual model was developed through inductive analysis to identify interrelationships between tourism-related themes. Findings & value added: The key findings highlight the transformative potential of strategies that align tourism practices with environmental stewardship, local empowerment, and innovative management approaches. The study underscores actionable implications such as the establishment of innovation hubs, and cross-sector partnerships, offering pathways to foster a tourism sector that not only supports global sustainable development goals, but also ensures long-term community resilience and equitable development.

Environmental Assessment of Farm Sustainability – A Hungarian Case Study

Koltai Judit Petra Nóra Gombköto

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 409-414

Description:

Agricultural production is inseparable from environmental sustainability, and several methods have been developed by numerous authors and organizations worldwide to measure and evaluate it. The aim of the study is to comprehensively and accurately assess the environmental sustainability of farms. Concerning the theoretical framework, a set of 8 indicators and 23 sub-indicators was established to estimate the different aspects of environmental sustainability. The practical compliance of the indicators was assessed based on data from Hungarian agricultural enterprises; an agricultural company and three individual farmers were included in the case studies. By grouping the indicators, a new composite environmental indicator was developed to measure environmental sustainability. The results of the study show that the surveyed farms are moderately sustainable, as their composite indicators were at or close to the minimum of 0.5 points, but none of them were outstanding or at least 0.75 points. More significant efforts should be made to improve the farms’ environmental sustainability in the future.

Description:

Several variations exist of the shortest path problem depending on the type of the graph. The most common problems are the shortest path problem between two points and between every pair of points (the so called multiterminal minimal path problem). Beside this several other variations are known. One of them is the shortest path in a network having gains, the time dependent path, the shortest path in a network, where the travelling time depends on the actual traffic flow. In this paper a powerful algorithm is presented in large scale, sparse network. In long term road network planning problem sometimes the size of the network is very large - about hundred thousand. The network is usually sparse, one point is connected with average 3 or 4 points. It will be shown that the presented algorithm in this case is much more powerful. © 2012 IEEE.

Publication Name: Buildings

Publication Date: 2025-08-01

Description:

The sustainability of bridge infrastructure is becoming increasingly important due to rising environmental, economic, and social demands. However, most current assessment models remain fragmented, often overlooking the social pillar, underutilizing risk integration across the lifecycle, and failing to fully leverage digital tools such as Building Information Modeling (BIM) and Life Cycle Sustainability Assessment (LCSA), resulting in incomplete sustainability evaluations. This study addresses these limitations by introducing a practical and adaptable model that integrates BIM, LCSA, and expert-driven risk prioritization. Five Hungarian bridge projects were modeled using Tekla Structures and analyzed in OpenLCA to quantify environmental, economic, and social performance. A custom Sustainability Level Change (SLC) algorithm was developed to compare baseline scenarios (equal weighting) with risk-informed alternatives, simulating the impact of targeted improvements. The results demonstrated that prioritizing high-risk sustainability indicators leads to measurable lifecycle gains, typically achieving SLC improvements between +2% and +6%. In critical cases, targeted enhancement scenarios, applying 5% and 10% improvements to top-ranked, high-risk indicators, pushed gains up to +12%. Even underperforming bridges exhibited performance enhancements when targeted actions were applied. The proposed framework is robust, standards-aligned, and methodologically adaptable to various bridge types and lifecycle phases through its data-driven architecture. It empowers infrastructure stakeholders to make more informed, risk-aware, and data-driven sustainability decisions, advancing best practices in bridge planning and evaluation. Compared to earlier tools that overlook risk dynamics and offer limited lifecycle coverage, this framework provides a more comprehensive, actionable, and multi-dimensional approach.
