Opis: Symmetry is an essential feature of many geometric objects. However, the world also contains many asymmetrical or approximately symmetrical objects. Detecting approximate symmetries is a rather weakly defined problem, as computer-detected approximate symmetry may not correspond to human opinion. The situation is even worse if the symmetry is not global but local. This paper investigates whether approximate local reflection symmetries found by a computer in real data are acceptable for human observers. To answer this question, a new simple approximate local reflection symmetry detection is proposed and run on land cadastre data in the form of planar point sets. The resulting symmetries are subject to user tests to study human acceptance of approximate local symmetry. The results show a relatively good correlation between symmetry detected by computers and perceived by humans. This finding provides a solid foundation for integrating both approaches in specific applications. To achieve this, further research is needed on how to utilize specific aspects of human symmetry perception in computer solutions, so that computer symmetry detection can better approximate human perception.

Opis: This research focuses on the question of how geothermal energy public perception is formed within a national context where news media do not pay attention to geothermal energy, and there is no active opposition to geothermal energy. The research builds on theoretical underpinnings of heuristics in energy perceptions and highlights the importance of physical experiences and associations as sources of experiential learning. Through a survey conducted among members of the general public in Slovenia, the role of thermal water recreation in shaping public perception of geothermal energy is empirically tested. The results show that, in this context, geothermal energy is highly positively assessed compared to hydro energy and nuclear energy, and that there is a correlation between frequency of thermal recreation and certain aspects of public perception of geothermal energy. The policy implications go beyond the simple recommendation of including tourism in public awareness campaigns but point to the specific vulnerability of energy acceptance in this context, where perceptions are formed based on “thinking fast”, and where the media and the public discourse on geothermal energy have not (yet) considered the potential risks and opposition to geothermal projects.

Opis: This paper investigates emerging technological trends in web commerce and examines user perceptions through a pilot survey. Key innovations include IoT, AI, ML, chatbots, social and voice commerce, as well as immersive technologies like AR and VR. These tools enhance personalization, automate services, and support better consumer decision-making. The pilot study, based on an online questionnaire, explores user behaviour, expectations, and attitudes toward these developments. Results show that while users are familiar with technologies like chatbots and personalization, awareness of AR and VR remains low. Concerns about security and data privacy significantly influence user trust. The findings highlight the need for seamless technological integration, increased user education, and transparent communication to build trust and improve the digital shopping experience.

Opis: The main purpose of this paper is to investigate how the number, perceived intensity, and frequency of sensory involvement in the consumer-brand relationship, impact brand perception. The research was conducted on a sample of 189 respondents from the Republic of Croatia. To test the hypotheses factor and regression analyses were used. The main findings of this research are: a) involvement of multiple senses in the consumer-brand relationship has a positive effect on brand perception; b) the greater the frequency of involving multiple senses in the consumer-brand relationship, the more positive effect it has on brand perception; and c) the higher intensity of sensory involvement in the consumer-brand relationship does not have a significant effect on brand perception. This research contributes to marketing and brand management literature by investigating importance of sensory marketing, more specifically number, perceived intensity, and frequency of sensory involvement on brand perception.

Opis: The patient safety culture is key to ensuring patient safety in healthcare organizations. The triage environment is inherently demanding for patient safety and is characterized by high stress, rapid decision-making, and quick action. In several countries, including Slovenia, there is a lack of studies on the patient safety culture among triage nurses. This study aimed to assess the perceptions of the patient safety culture among triage nurses. A cross-sectional survey design was used. The Emergency Medical Services-Safety Attitudes Questionnaire, distributed to triage nurses, was used to collect data. A total of 201 triage nurses participated in this study. The results revealed that the overall average perception of the patient safety culture was 57.27% (SD = 57.27), indicating that the perception of the patient safety culture among triage nurses in the emergency department was non-positive and requires improvement. “Job Satisfaction” received the highest score (63.18%; SD = 17.19), while “Working Conditions” received the lowest (49.91%; SD = 17.37). The perception of positive and negative safety culture responses was statistically significant for age (χ2 (3) = 17.750, p ≤ 0.001), education (χ2 (2) = 6.957, p = 0.031) and length of working experience (χ2 (3) = 8.875, p = 0.031). The findings emphasize the significance of improving the safety culture in relation to several areas of patient care during the triage process. This research serves as a crucial foundation for enhancing patient safety in triage, providing quality care, and reducing adverse events.
