1. The (in)effectiveness of attention guidance methods for enhancing brand memory in 360° videoJani Pavlič, Tina Tomažič, 2022, original scientific article Abstract: Sensing and remembering features in visual scenes are conditioned by visual attention
and methods to guide it. This should be relevant in terms of product placement, which has become
an important part of incorporating brands into different mass media formats with a commercial
purpose. The approach can be challenging in 360◦ video, where an omnidirectional view enables
consumers to choose different viewing perspectives, which may result in overlooking the brands.
Accordingly, attention guidance methods should be applied. This study is the first to explore diegetic
guidance methods as the only appropriate guiding method for an unobtrusive and unconscious
nature of product placement. To test the effectiveness of three different diegetic guiding methods,
a between-subject design was employed, where the participants were assigned randomly to one
of four videos with the same scene but different guiding methods. The findings show and explain
the discrepancy with studies on guiding attention in other contexts, as there were no significant
differences between the guiding cues according to brand recall and brand recognition. The results also indicate a significant influence of brand familiarity on brand recall in 360◦ video. The
article concludes by providing limitations, future research directions, and recommendations for
audiovisual policy.

2. Numerical study of racking resistance of timber-made double-skin façade elementsErika Kozem Šilih, Miroslav Premrov, 2022, original scientific article Abstract: The use of a double-skin façade (DSF) is a quite new approach in the building renovation process, complementing conventional renovation strategies. A double-skin façade is an envelope wall construction that consists of two transparent surfaces separated by a cavity and can essentially improve the thermal and acoustic resistance of the building envelope. The main double-skin wall components are usually composed of a hardened external single glazing pane and a double or triple thermal insulating internal glass pane, which are connected to the frame structure. Recently, many studies have analysed the thermal and acoustic performance of DSF elements, but almost none in terms of structural behaviour, especially in terms of determining the racking resistance of such wall elements. Moreover, with a view to reduce the global warming potential, an eco-friendly timber frame instead of a commonly used steel, aluminium or plastic frame is studied in this analysis. However, structurally combining timber and glass to develop an appropriate load-bearing structural element is a very complex process involving a combination of two materials with different material properties, where the type of bonding can be selected as a crucial parameter affecting the racking resistance range. Since the costs of experiments performed on such full-scale DSF elements are very high and such experiments are time-consuming, it is crucial to develop special mathematical models for analysing the influence of the most important parameters. Therefore, the main goal of this paper is to develop the finite element mathematical model of the studied DSF structural elements with a highly ecological solution by using a timber frame. In the second step, the developed model is further implemented in the numerical analysis of racking stiffness and followed by a comprehensive parametric numerical study on different parameters influencing the horizontal load-bearing capacity of such DSF timber elements. The obtained results indicate that the new approach of the developed load-bearing prefabricated timber DSF elements can essentially improve racking resistance and stiffness compared with the widely studied timber-glass single-skin wall elements and can thus be fully recommended especially in the structural renovation process of old buildings.

4. An overview of the current state of cell viability assessment methods using OECD classificationEneko Madorran, Miha Ambrož, Jure Knez, Monika Sobočan, 2025, review article Abstract: Over the past century, numerous methods for assessing cell viability have been
developed, and there are many different ways to categorize these methods accordingly. We
have chosen to use the Organisation for Economic Co-operation and Development (OECD)
classification due to its regulatory importance. The OECD categorizes these methods
into four groups: non-invasive cell structure damage, invasive cell structure damage, cell
growth, and cellular metabolism. Despite the variety of cell viability methods available,
they can all be categorized within these four groups, except for two novel methods based
on the cell membrane potential, which we added to the list. Each method operates on
different principles and has its own advantages and disadvantages, making it essential
for researchers to choose the method that best fits their experimental design. This review
aims to assist researchers in making this decision by describing these methods regarding
their potential use and providing direct references to the cell viability assessment methods.
Additionally, we use the OECD classification to facilitate potential regulatory use and to
highlight the need for adding a new category to their list.

5. Comparative Study of GPR Acquisition Methods for Shallow Buried Object DetectionPrimož Smogavec, Blaž Pongrac, Andrej Sarjaš, Venceslav Kafedziski, Nabojša Dončov, Dušan Gleich, 2024, original scientific article Abstract: This paper investigates the use of ground-penetrating radar (GPR) technology for detecting shallow buried objects, utilizing an air-coupled stepped frequency continuous wave (SFCW) radar system that operates within a 2 GHz bandwidth starting at 500 MHz. Different GPR data acquisition methods for air-coupled systems are compared, specifically down-looking, side-looking, and circular acquisition strategies, employing the back projection algorithm to provide focusing of the acquired GPR data. Experimental results showed that the GPR can penetrate up to 0.6 m below the surface in a down-looking mode. The developed radar and the back projection focusing algorithm were used to acquire data in the side-looking and circular mode, providing focused images with a resolution of 0.1 m and detecting subsurface objects up to 0.3 m below the surface. The proposed approach transforms B-scans of the GPR-based data into 2D images. The provided approach has significant potential for advancing shallow object detection capabilities by transforming hyperbola-based features into point-like features.

6. Spatial modelling of modal shift due to COVID-19Simona Šinko, Klemen Prah, Tomaž Kramberger, 2021, original scientific article Abstract: The outbreak of COVID-19 caused many changes in people's life. One of the most significant is the travel behaviour and transport mode choice. This study focus on the changes that the inhabitants of Vienna made in their travel choices because of the virus. The same research about spatial modelling the transport mode choice of commuters in Vienna was completed in 2019 and is a topic addressed in our previous work. Based on our developed methodology, this article indicates that public transport is not a dominant transport mode choice as it was before the virus outbreak.The main result of this paper is geographically defined areas of application of individual alternatives shown on the final map of modal shift in Vienna, which could provide theoretical support for policy-makers and transportation planners. For the city of Vienna, we found that the area of the city where cars are now used has increased, which certainly has a negative impact on air quality and life in the city. The advantage of the methodology is that it can also be applied to other cities in the world.

7. Identification and ranking of core values in family medicine : a mixed methods study from UkrainePavlo Kolesnyk, Sabine Bayen, Ivanna Shushman, Andrew Kolesnyk, George Kuodza, Zalika Klemenc-Ketiš, Thomas Frese, 2021, original scientific article Abstract: Introduction/Context: The term core value (CV) can be defined as fundamental beliefs or principles, guiding one's behavior in a social context. Though core competencies of family medicine (FM) have been clearly defined by WONCA, there has been an ongoing debate on what the CVs are for family doctors (FDs). Ukraine is a developing country in the middle of Europe with a population of 43 million inhabitants, gained independence from the Soviet Union in 1991. Ukraine is a low-income country, developing a modern European healthcare system, especially regarding FM. To implement WONCA standards, it is mandatory to assess the ongoing understanding of CVs in clinical daily practice among active FDs, working in different countries of Europe including Ukraine. Research questions: How do Ukrainian FDs (Delphi group experts) define the CVs of FM in Ukraine and how important are these CVs to a wider population of Ukrainian FDs in their everyday practice? Methods: A mixed method study was conducted in two steps during August and September 2020 in Ukraine. The first part was a qualitative Delphi round (three rounds) design among 20 Ukrainian FDs who were familiar with teaching and terms like CV. A consensus list of six CVs has emerged from the Delphi round study. The second part was a quantitative survey among Ukrainian FDs, who were not specially used to discussing CVs. The consensus list of those six CVs was then submitted to 2000 FDs (randomly selected) who were not involved in the Delphi team, to rank those values from one to nine, according to the importance from their personal point of view. Demographic characteristics have been assessed for all the participants of the Delphi round and quantitative survey. Results: Twenty FDs were involved as experts in the first Delphi round, whereas only five experts continued their participation in the second and the third rounds of the survey. The following six CVs emerged from the Delphi round: comprehensive approach, care coordination, first recourse, continuity of care, integrated approach, and patient and family centered care. The final sample consisted of 375 FDs (19% response rate). There were 323 (88.7%) female and 34 (9.3%) male FDs in the sample. The mean age of the participants was 44.6+-13.5 years. Discussion/Conclusion: Defining CVs for FM by Ukrainian FDs in a given socio-economical and historical-cultural setting is crucial to optimize primary medical care and to guarantee an appropriate and successful implementation of WONCA standards as well as CVs in different countries including those where reformation of the health system is ongoing.

8. Methods and models for electric load forecasting : a comprehensive reviewMahmoud A. Hammad, Borut Jereb, Bojan Rosi, Dejan Dragan, 2020, original scientific article Abstract: Electric load forecasting (ELF) is a vital process in the planning of the electricity industry and plays a crucial role in electric capacity scheduling and power systems management and, therefore, it has attracted increasing academic interest. Hence, the accuracy of electric load forecasting has great importance for energy generating capacity scheduling and power system management. This paper presents a review of forecasting methods and models for electricity load. About 45 academic papers have been used for the comparison based on specified criteria such as time frame, inputs, outputs, the scale of the project, and value. The review reveals that despite the relative simplicity of all reviewed models, the regression analysis is still widely used and efficient for long-term forecasting. As for short-term predictions, machine learning or artificial intelligence-based models such as Artificial Neural Networks (ANN), Support Vector Machines (SVM), and Fuzzy logic are favored.

9. Risk factors for systemic reactions in typical cold urticaria : results from the COLD-CE studyMitja Košnik, Dejan Dinevski, Simon Francis Thomsen, Daria Fomina, Elena Borzova, Kanokvalai Kulthanan, Raisa Meshkova, Dalia Melina Ahsan, Mona Al-Ahmad, Jovan Miljković, Dorothea Terhorst, 2022, original scientific article Abstract: Background: Cold urticaria (ColdU), i.e. the occurrence of wheals or angioedema in response to cold exposure, is classified into typical and atypical forms. The diagnosis of typical ColdU relies on whealing in response to local cold stimulation testing (CST). It can also manifest with cold-induced anaphylaxis (ColdA). We aimed to determine risk factors for ColdA in typical ColdU.
Methods: An international, cross-sectional study COLD-CE was carried out at 32 urticaria centers of reference and excellence (UCAREs). Detailed history was taken and CST with an ice cube and/or TempTest® performed. ColdA was defined as an acute cold-induced involvement of the skin and/or visible mucosal tissue and at least one of: cardiovascular manifestations, difficulty breathing, or gastrointestinal symptoms.
Results: Of 551 ColdU patients, 75% (n=412) had a positive CST and ColdA occurred in 37% (n=151) of the latter. Cold-induced generalized wheals, angioedema, acral swelling, oropharyngeal/laryngeal symptoms, and itch of earlobes were identified as signs/symptoms of severe disease. ColdA was most commonly provoked by complete cold water immersion and ColdA caused by cold air was more common in countries with a warmer climate. Ten percent (n=40) of typical ColdU patients had a concomitant chronic spontaneous urticaria (CSU). They had a lower frequency of ColdA than those without CSU (4% vs 39%, p=0.003). We identified the following risk factors for cardiovascular manifestations: previous systemic reaction to a Hymenoptera sting, angioedema, oropharyngeal/laryngeal symptoms, and itchy earlobes.
Conclusion: ColdA is common in typical ColdU. High-risk patients require education about their condition and how to use an adrenaline autoinjector.

10. Analysis and evaluation of user experience in mobile applications with modern interaction methods : magistrsko deloKatja Frančič, 2024, master's thesis Abstract: Mobile devices, seamlessly weaving artificial intelligence into their applications, have become indispensable for millions of people in their daily lives. In our master’s thesis, we explored methods for evaluating user experience, focusing on those suitable for modern mobile applications. In the applied phase, participants evaluated three mobile apps using distinct questionnaires. This affirmed the positive correlation between user interface simplicity and enhanced UX, alongside modern interaction methods fostering increased user loyalty. Our findings confirm that post-task questionnaires offer deeper insights into UX, with users showing a preference for completing them. While gender may influence user experience, it's not the sole determinant.
