The idea that digital remote learning can happen anytime, anywhere in forced online teacher education is a myth
Andrej Šorgo, Mateja Ploj Virtič, Kosta Dolenc, 2023, izvirni znanstveni članek

Opis: An involuntary international experiment in which the entire student population was switched to digital remote learning due to the measures to stop COVID-19 put the paradigm of "anytime, anywhere learning" to the test. Online survey responses were obtained from 281 preservice primary and subject teachers. Using Structural Equation Modelling, connections were examined by inspection of path coefcients between constructs quality of personal digital technology, satisfaction, health, well-being, motivation, and physical activity. Problems with the quality of personal digital technology had a moderate infuence on all constructs except motivation. Satisfaction infuenced all constructs, well-being, and health the most. When comparing responses of the bottom and top third students based on the quality of personal digital technology, it was found that students who did not have the appropriate technology and workspace were less satisfed and sufered more. This is refected in an increased incidence of problems related to health, well-being, and physical activity, along with a decrease in motivation. At least for the technologically deprived, the paradigm of "anytime, anywhere learning" is a myth. The study highlights the need for educational institutions to provide adequate technology and workspaces for all students in order to support their well-being and motivation during remote learning.

Aquaponics for the Anthropocene : towards a "sustainability first" agenda
James Gott, Rolf Morgenstern, Maja Turnšek, 2019, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: ‘The Anthropocene’ has emerged as a unique moment in earth history where humanity recognises its devastating capacity to destabilise the planetary processes upon which it depends. Modern agriculture plays a central role in this problematic. Food production innovations are needed that exceed traditional paradigms of the Green Revolution whilst at the same time are able to acknowledge the complexity arising from the sustainability and food security issues that mark our times. Aquaponics is one technological innovation that promises to contribute much towards these imperatives. But this emergent field is in an early stage that is characterised by limited resources, market uncertainty, institutional resistance and high risks of failure—a developmental environment where hype prevails over demonstrated outcomes. Given this situation, the aquaponics research community potentially holds an important place in the development path of this technology. But the field needs to craft a coherent and viable vision for this technology that can move beyond misplaced techno-optimist accounts. Turning to sustainability science and STS research, we discuss the urgent need to develop what we call a ‘critical sustainability knowledge’ for aquaponics, giving pointers for possible ways forward, which include (1) expanding aquaponic research into an interdisciplinary research domain, (2) opening research up to participatory approaches in real-world contexts and (3) pursuing a solution-oriented approach for sustainability and food security outcomes.

Use of mobile technologies in tourism : natural health resorts study
Boštjan Brumen, Peter Planinc, Tomi Špindler, Mitja Gorenak, Tanja Lešnik Štuhec, 2020, izvirni znanstveni članek

Opis: Mobile technologies have drastically changed the way people do everyday activities. Tasks previously reserved for desktop environments have moved to mobile devices, and nowadays, half of the internet traffic is stemming from mobile devices. The tourism industry is no exempt from the shift from desktop to mobile. In our research, we check to what extent natural health resorts have adapted and integrated mobile solutions to their websites. We collected data about the friendliness of selected websites using automated online tools and carried out a heuristic evaluation. The results were statistically analyzed and compared. Only roughly half of natural health resorts have optimized their websites for mobile devices. There are no statistically significant differences when comparing purely technical aspects. However, an in-depth heuristic evaluation has shown that some web sites are significantly more mobile-friendly than others and offer better technical conditions for enhanced user experience. Our study is the first technical and contentual evaluation of website mobile devices' friendliness in the natural health resort sector. It warns management, their marketing consultants, and web site developers about the opportunities they are missing by not supporting mobile users sufficiently. Further, it outlines deficiencies and provides suggestions and instructions for optimizing websites to enhance user-friendliness on mobile devices.

Barriers to applying last-mile logistics in the Egyptian market : an extension of the technology acceptance model
Mohamed Amr Sultan, Tomaž Kramberger, Mahmoud Barakat, Ahmed Hussein Ali, 2023, izvirni znanstveni članek

Opis: Drawing on the Technology Acceptance Model (TAM), this research aims to investigate the impact of social, environmental, and technological barriers on adopting the last-mile logistics application. This research used a self-administrative questionnaire to collect 1060 respondents from the Egyptian market and analysed it using partial least square structural equation modeling. The findings revealed that some elements could obstruct the implementation of last-mile delivery technologies, namely complexity, collaboration efforts between users and application developers and the impact of technical knowledge and expertise on the potentially involved users. The sharing economy helps organisations reduce contaminants, emissions and carbon footprints, and last-mile logistics is one of the tools of the sharing economy that can enhance the productivity and competitiveness of logistics and boost consumer fulfillment. This research will help enhance organisations’ performance in Egypt as a developing country and push towards applying environmental sustainability practices, as it introduces a tool to enhance customer satisfaction and reduce emissions by illustrating how last-mile logistics can be implemented. This is particularly important as last-mile logistics face some implementation barriers, especially in developing countries. In addition, it will help in extending the theory through conceptualising its abstract ideas with the research variables and applying it in a different context.

Simultaneous use of digital technologies and industrial robots in manufacturing firms
Klemen Kovič, Robert Ojsteršek, Iztok Palčič, 2023, izvirni znanstveni članek

Opis: This paper presents the use of digital technologies and industrial robots in manufacturing firms. More importantly, we look at the relationship between the use of digital technologies and industrial robots within the Industry 4.0 concept. We also use a specific Industry 4.0 Readiness index to assess manufacturing firms’ Industry 4.0 readiness level and analyze the relationship between the achieved readiness level and the use of industrial robots. The research is based on data from 118 manufacturing firms from a European Manufacturing Survey. Based on statistical analysis, we present the results that show a significant correlation between the use of specific digital technologies and two types of industrial robots. Our study also points out that manufacturing firms with a higher Industry 4.0 readiness level tend to use industrial robots more frequently.

A regenerator used in the installation of magnetic refrigeration devices
Dorin Botoc, Jurij Avsec, Adrian Plesca, 2020, strokovni članek

Opis: In this article, the mechanism and functioning of a refrigeration system based on the magnetic system and the magnetocaloric effect are examined. Magnetic refrigeration plants operate based on a state-of-the-art technology that does not contain any toxic refrigerant that is harmful to the environment and the ozone layer. The magnetocaloric effect is created by a rare earth metal called gadolinium. We have studied the benefits of using this type of mechanism for both domestic and industrial needs. High efficiency, net energy consumption lower than the classic, silent systems, and a lack of typical refrigerant characterize this type of installation. The following layout describes the initial prototype for AMR in magnetocaloric refrigeration.

Jure Trdin, 2023, magistrsko delo

Opis: In the space industry, the continuous effort to reduce the weight of structural components is of utmost importance due to the high cost of launching mass into space. Structural analyses and optimizations with numerical methods play a crucial role in achieving this goal by minimizing material usage while ensuring structural integrity. The objective of this dissertation is to implement and demonstrate the accuracy and effectiveness of meshless methods in numerical studies compared to the Finite Element Method (FEM), focusing on designing cost-effective and lightweight components. Through benchmark examples and extensive research on optimal parameters, the accuracy and effectiveness of these methods are established. Furthermore, practical application is demonstrated by optimizing the spoke of NASA's Rover Perseverance wheel, resulting in more optimized structures with significantly reduced mass and lower mechanical stresses. Additionally, analysis of different materials for the wheel's spoke is performed with the aim of further reducing mass and increasing performance. By utilizing structural optimization, this work not only highlights the diverse applications and benefits of integrating structural optimization in the product design phase but also contributes to the ongoing efforts in the space industry to reduce material mass and enhance performance, addressing the challenges associated with launching mass into space while ensuring the adequate structural resistance. Furthermore, this thesis also contributes to the development of the meshless methods in structural optimization, showcasing its effectiveness and potentials.
