Volume: 9

Issue: 2

Page Range: 118-128

Description:

EU funds that are available in Serbia are modest both in volume and number, since Serbia received preaccession status only in 2014. Before that, it was only a potential pre-accession country on the external border of the European Union. From the five components of IPA (2007-2013) Serbia could have utilised only the first two components in the pre-accession process: building of EU institutions (EXCHANGE IIV, Regional Socio-Economic Development Programme) and enhancing cross-border cooperation As a conclusion we can say that although substantial sums were invested from the above mentioned resources into the economy of Vojvodina for its development, the main indicator - the GDP - has been increasing only slightly, while these projects have no effects on decreasing unemployment. In the overall economic situation, unemployment is primarily decreased by emigration, in which Vojvodina Hungarians take part at a rate above the average compared to their headcount, thus decreasing the economic power of the community through emigration.

Description:

The integration of artificial intelligence (AI) into human-robot interaction (HRI) in healthcare has fundamentally revolutionized the emotional, social, and cognitive interaction between humans and robotic systems. This systematic review examines how AI-powered healthcare bots affect patient trust, therapeutic alliance, and user bonding. A PRISMA-compliant literature search was conducted in five major databases: PubMed, Scopus, IEEE Xplore, Springer, and MDPI, covering studies published in English between 2010 and 2025. The inclusion criteria targeted experimental research, including evaluation studies, of AI-enhanced HRI in clinical and assistive fields. Reviews, non-experimental work, and studies without AI integration were excluded. Methodological quality and risk of bias were assessed using the revised Cochrane Risk of Bias tool for randomized trials (RoB 2), while robvis was used to generate visual summaries of the risk-of-bias assessments. Meta-analysis calculated Diagnostic Odds Ratios (95% CI) for reported diagnostic outcomes. Bibliometric visualization was performed using VOSviewer. The results show that visualized and emotionally intelligent robots outperformed virtual agents in delivering emotional security and therapeutic value. However, diagnostic accuracy was low (AUC≈0.39; pooled specificity = 0.53) with substantial heterogeneity (I2 ˜ 68%), and meta-regression identified no significant moderators, leaving residual variability (τ2 = 0.479). Gaps between user expectations and responsiveness limited engagement, and limited longitudinal designs restricted long-term insights. RoB 2 indicated moderate methodological variability. Despite these constraints, culturally adaptive robotic systems enhance clinical communication and patient trust, underscoring the importance of personalization and emotional intelligence in future AI healthcare robots.

Ukrainian students on the global map of academic migration

Yuriy Bilan Olha Hrynkevych Halyna Mishchuk Natalia Samoliuk

Publication Name: Problems and Perspectives in Management

Publication Date: 2024-01-01

Volume: 22

Issue: 4

Page Range: 558-575

Description:

Considering the loss of talented youth in Ukraine caused by migration, there is a growing need to investigate how to attract and retain students. The study aims to identify the peculiarities of Ukrainian student migration against the background of global patterns of academic migration, focusing on factors of countries' attractiveness for the students. The typology of countries by the level of inbound and outbound academic migration is developed based on variation analysis. The correlation analysis is used to identify the factors that influence countries' attractiveness to students. The analysis of educational policies of the most attractive countries for Ukrainian students is fulfilled using the contextual analysis of legislative norms on academic mobility. In the global dimension, the variation of both inbound and outbound academic mobility is closely related to a country's economic level, measured by GNI per capita. However, the correlation analysis did not confirm the higher migration attractiveness of countries with a high level of economic development (correlation with GNI per capita is -0.147). The impact of employment and social and economic resilience of an economy was relatively significant, with the correlation coefficients of 0.426 and 0.371. The analysis of educational policies of host countries showed the active use of language integration tools, the combined use of financial mechanisms, and the involvement of universities in career development. Implementation of the best practices of educational management in Ukraine is critical for restoring demographic and intellectual capital.

Volume: 17

Issue: 7 July

Page Range: Unknown

Description:

The research presents an analysis of the food security policy effectiveness on the component of food availability and access in two developing countries, Colombia and Kyrgyzstan, during the period from 2000 to 2018. Determining the state of their food balance trade and the regression analysis for the Food Production Index of the countries, considering four economic indicators. Thus the study attempts to show that policies and strategies have not reached the expected results in terms of reduction of food imports dependency and strengthening of national production and export industry. Furthermore was found that among the economic indicators considered, food inflation, food imports, food exports, and extreme monetary poverty; the last one was the indicator that presented influence on the Food Production Index of both countries, during the period analyzed, showing that access was the main component that defines the food production. The results highlighted the need of integrating food security with the monetary and trade policies of these countries.

Description:

Head-Related Transfer Functions (HRTFs) are frequently used in virtual audio scene rendering in order to simulate sound sources at different spatial locations. The use of dummy-head HRTFs (also referred as generic sets) is often criticized because of poor localization performance, leading to e.g. lower spatial resolution, in-thehead localization, front-back reversals etc. This paper presents results of horizontal plane localization obtained by digital filter representations of dummy-head HRTFs that were recorded normally, and using additional cap, glasses and hair on the head. Results of untrained subjects over equalized reference headphones showed no significant difference among the HRTF sets despite of large magnitude differences. This method for customization of generic HRTFs fails if improvement in localization is needed.

Description:

This paper focuses on auditory sensory substitution for providing visually impaired users with suitable information in both static scene recognition and dynamic obstacle avoidance. We introduce three different sonification models together with three temporal presentation schemes, i.e. ways of temporally organizing the sonic events in order to provide suitable information. Following an overview of the motivation and challenges behind each of the solutions, we describe their implementation and an evaluation of their relative strengths and weaknesses based on a set of experiments conducted in a virtual environment.

Description:

Capabilities of the auditory memory system were tested in a serious game application developed for the Android mobile platform. Participants played the well-known game of finding pairs by flipping and remembering objects on cards arranged in a matrix structure. Visual objects were replaced by iconic auditory events (auditory icons, earcons). Total time and different error rates were recorded and the effect of training was also evaluated. Results indicate that training contributes to a better performance and human voice samples are the easiest to remember.

Description:

Designing turbulence promoters with optimal geometry and using them for ultrafiltration systems has been a key challenge in mitigating membrane fouling. In this study, six different turbulence promoters were created using three-dimensional printing technology and applied in dead-end ultrafiltration. Three-dimensional-printed (3DP) turbulence promoter configurations were integrated into a classical batch ultrafiltration cell. The effects of these configurations and the stirring speeds on the permeate filtration flux, organic rejections, and membrane resistances were investigated. The fouling control efficiency of the 3DP promoters was evaluated using two polyethersulfone membranes in a stirred ultrafiltration cell with model dairy wastewater. The Hermia and resistance-in-series models were studied to further investigate the membrane fouling mechanism. Of the Hermia models, the cake layer model best described the fouling in this membrane filtration system. It can be concluded that the 3DP turbulence promoters, combined with intense mechanical stirring, show great promise in terms of permeate flux enhancement and membrane fouling mitigation. Using a well-designed 3DP turbulence promoter improves the hydrodynamic flow conditions on the surface of the stirred membrane separation cells based on computational fluid dynamics modeling. Therefore, the factors effecting the fabrication of 3DP turbulence promoters are important, and further research should be devoted to revealing them.

Description:

In traditional industry setups, Automated Guided Vehicles (AGVs) follow trajectories planned together with the layout of the storage or production facility and supported by fixed markers on the floor or on the walls. Traffic rules manage the avoidance of multiple vehicles, while fleet management gets movement and transportation commands completed as soon as possible. In contrast, recent developments in navigation and advanced computing, sensor, and communication capabilities make their free movement safe and manageable. Detailed route planning and scheduling can guarantee that the vehicles keep a safe distance in time and space. A recent challenge of electric AGVs is that their charging may take several hours, which must be factored into their schedule. This has made minimal energy demand a key objective alongside earliest delivery and strictly meeting the deadlines. This paper presents a method for detailed routing and scheduling of AGV fleets to minimize energy consumption while considering battery levels and charging times. The optimization method is illustrated by a case study where multiple delivery tasks are performed by synchronized movement of vehicles on a complex warehouse layout. In the optimal solution, the scheduled waiting times for collision avoidance are utilized by the vehicles to pre-charge their batteries.
