Span of a graph : keeping the safety distance
Iztok Banič, Andrej Taranenko, 2023, izvirni znanstveni članek

Opis: Inspired by Lelek's idea from [Disjoint mappings and the span of spaces, Fund. Math. 55 (1964), 199 -- 214], we introduce the novel notion of the span of graphs. Using this, we solve the problem of determining the \emph{maximal safety distance} two players can keep at all times while traversing a graph. Moreover, their moves must be made with respect to certain move rules. For this purpose, we introduce different variants of a span of a given connected graph. All the variants model the maximum safety distance kept by two players in a graph traversal, where the players may only move with accordance to a specific set of rules, and their goal: visit either all vertices, or all edges. For each variant, we show that the solution can be obtained by considering only connected subgraphs of a graph product and the projections to the factors. We characterise graphs in which it is impossible to keep a positive safety distance at all moments in time. Finally, we present a polynomial time algorithm that determines the chosen span variant of a given graph.

Recommendations for wider adoption of clinical pharmacy in Central and Eastern Europe in order to optimise pharmacotherapy and improve patient outcomes
Kamila Urbańczyk, Sonja Guntschnig, Vasilis Antoniadis, Slaven Falamić, Tijana Kovacevic, Marta Kurczewska-Michalak, Branislava Miljković, Anna Olearova, Inese Sviestina, Attila Szucs, Matej Štuhec, 2023, pregledni znanstveni članek

Opis: Clinical pharmacy as an area of practice, education and research started developing around the 1960s when pharmacists across the globe gradually identified the need to focus more on ensuring the appropriate use of medicines to improve patient outcomes rather than being engaged in manufacturing and supply. Since that time numerous studies have shown the positive impact of clinical pharmacy services (CPS). The need for wider adoption of CPS worldwide becomes urgent, as the global population ages, and the prevalence of polypharmacy as well as shortage of healthcare professionals is rising. At the same time, there is great pressure to provide both high-quality and cost-effective health services. All these challenges urgently require the adoption of a new paradigm of healthcare system architecture. One of the most appropriate answers to these challenges is to increase the utilization of the potential of highly educated and skilled professionals widely available in these countries, i.e., pharmacists, who are well positioned to prevent and manage drug-related problems together with ensuring safe and effective use of medications with further care relating to medication adherence. Unfortunately, CPS are still underdeveloped and underutilized in some parts of Europe, namely, in most of the Central and Eastern European (CEE) countries. This paper reviews current situation of CPS development in CEE countries and the prospects for the future of CPS in that region.

Resveratrol food supplement products and the challenges of accurate label information to ensure food safety for consumers
Maja Bensa, Irena Vovk, Vesna Glavnik, 2023, izvirni znanstveni članek

Opis: The food supplement market is growing as many consumers wish to complement their nutrient intake. Despite all the regulations in place to ensure food supplements safety, there are still many cases of irregularities reported especially connected to internet sales. Twenty resveratrol food supplement products sold on the Slovenian market were evaluated on their compliance of declared vs. determined resveratrol content, as well as the compliance of labels with the European Union (EU) and Slovenian regulatory requirements. Both the ingredient contents and food information are important parts of food safety. Analyses of 20 food supplements performed using high-performance thin-layer chromatography (HPTLC) coupled with densitometry showed that 95% of products had contents different from what was declared and 55% of products contained higher contents than declared. In 25% of the products the determined content per unit exceeded the maximum level (150 mg/day) specified in EU novel food conditions for food supplement with trans-resveratrol. Evaluation of the 20 food supplement labels included mandatory and voluntary food information, food supplement information, novel food information, health claims and nutrition claims. Most labels contained the necessary information, but multiple errors were observed ranging from typos to misleading practices. From a food safety perspective there is still a lot of improvement needed in the field of food supplements.

The safety of patient management in family medicine in Slovenia during Covid-19 : a crosssectional study
Maja Cvetko Gomezelj, Špela Miroševič, Alina Verdnik Tajki, Ksenija Tušek-Bunc, Esther Van Poel, Sara Willems, Zalika Klemenc-Ketiš, 2023, izvirni znanstveni članek

Opis: Abstract Background During the Covid-19 pandemic, family medicine practices (FMPs) changed to improve safety against new coronavirus infections for both patients and employees. Protocols for treating patients with suspected Sars-Cov-2 infections were established to protect medical staf and other patients from being infected. However, these protocols also led to increased safety risks, such as delays in treating patients with other medical conditions. This exploratory study aimed to investigate safety risks in treating patients in FMPs during the Covid-19 pandemic and to suggest improvements to prevent Covid-19 in FMPs in Slovenia. Methods A cross-sectional study was rolled out in FMPs in Slovenia as part of the international Pricov-19 study. Data collection on safety management during the Covid-19 pandemic in FMPs in Slovenia took place from November 2020 until January 2021 using a self-administered online survey for FP working in Slovenia. A chi-square test, ANOVA, independent samples t-test or bivariate correlation test was performed to explore associations regarding the safety of patients’ management variables. Results From the 191 participating family physicians (FPs) (15.2% response rate), 54.8% reported having treated patients with fever (not Covid-19) late due to the new protocols at least once, and 54.8% reported patients with urgent conditions having been seen late at least once due to not coming. In the suburbs and rural environments FPs more often reported that at least once patient with a fever (not Covid-19) was seen late due to the protocol (p=0.017) and more often reported that at least once patient with an urgent condition was seen late due to not com‑ ing to their FP (p=0.017). The larger the practice, the more they reported that at least once a patient with fever (not Covid-19) was seen late due to the protocol (p=0.012) and the more they reported at least once a patient with an urgent condition was seen late due to not coming to their FP (p=0.012). Conclusion Covid-19 afected the safety of patient management in FMP in Slovenia. The most common prob‑ lem was foregone care. Therefor, protocols for chronic patient management in the event of epidemics need to be established.

Safety culture in the operating room : translation, validation of the safety attitudes questionnaire - operating room version
Teodor Pevec, Tit Albreht, Eva Turk, 2023, izvirni znanstveni članek

Opis: Background: Measuring the safety culture in Healthcare is an important step in improving patient safety. One of the most commonly used instruments to measure the safety climate is the Safety Attitudes Questionnaire (SAQ). The aim of the current study was to establish the validity and reliability of the Slovenian version of the SAQ for the operating room SAQ-OR. Methods: The SAQ, consisting of six dimensions, was translated and adapted to the Slovenian context and applied in operating rooms from seven out of ten Slovenian regional hospitals. Cronbach's alpha and confirmatory factor analysis (CFA) was used to evaluate the reliability and validity of the instrument. Results: The sample consisted of 243 health care professionals who hold positions in the OR, divided into 4 distinct professional classes, namely, 76 surgeons (31%), 15 anesthesiologists (6%), 140 nurses (58%) and 12 auxiliary persons (5%). It was observed a very good Cronbach's alpha (0.77 to 0.88). The CFA and its goodness-of-fit indices (CFI 0.912, TLI 0.900, RMSE 0.056, SRMR 0.056) showed an acceptable model fit. There are 28 items in the final model. Conclusions: The Slovenian version of the SAQ-OR revealed good psychometric properties for studying the organisational safety culture.

Food risk analysis : Towards a better understanding of “hazard” and “risk” in EU food legislation
Ana-Andreea Cioca, Livija Tušar, Tomaž Langerholc, 2023, izvirni znanstveni članek

Opis: For risk communication, it is important to understand the difference between “hazard” and “risk”. Definitions can be found in Codex Alimentarius and the European Union (EU) General Food Regulation (EC) No. 178/2002. The use of these terms as synonyms or their interchange is a recurrent issue in the area of food safety, despite awareness-raising messages sent by EFSA (European Food Safety Authority) and other interested entities. A quick screening of the EU’s food regulations revealed several inconsistencies. Hence, it was considered necessary to further investigate if regulations could act as a source for this problem. A software tool was developed to support the detection and listing of inconsistent translations of “hazard” and “risk” in certain EU food regulations. Subsequently, native-speaking experts working in food safety from each EU country were asked to provide their individual scientific opinion on the prepared list. All data were statistically analysed after applying numerical scores (1–5) describing different levels of consistency. Results showed that the most common problem was the interchange of “hazard” with “risk” and vice versa. This lack of consistency can create confusion that can further translate into misjudgments at food risk assessment and communication levels.

Visiting nuclear reactors : safety and security aspects
Barbara Pavlakovič Farrell, 2022, izvirni znanstveni članek

Opis: Visiting nuclear reactors is a niche tourism offer within energy (industrial) tourism, which leads tourists through areas that are not primarily meant for them. Hence, safety and security issues are even more critical in this case. This study aims to highlight different aspects of safety and security issues in nuclear power plant tours and to present measures taken to address these concerns. In addition, we studied the connection between plant visits and the public image of nuclear energy. Information was gathered through participant observation (personal visits of factory tours) and an online survey. There, we identified safety and security nuclear power plant visit protocols and a positive correlation between the visit variable and the two variables of the public image of nuclear energy, which suggests energy (industrial) tourism as a suitable tool to enhance awareness and knowledge about nuclear energy.

Work of Ljubljana’s Municipal Warden Service – from repression to prevention and collaboration
Tinkara Bulovec, Roman Fortuna, 2023, izvirni znanstveni članek

Opis: Purpose: This article highlights the work of Ljubljana’s Municipal Warden Service (MWS), emphasizing the application of criminological knowledge in both preventive and repressive efforts. Design/Methods/Approach: We performed both qualitative and quantitative analyses using data from the SUDMR and PowerBI apps, employed by municipal wardens to track preventive actions and map repressive measures. Findings: In recent years, there has been a significant increase in both repressive and preventive actions of municipal wardens, with 115,453 measures implemented and 2,752 hours allocated to preventive work in 2022. The majority of repressive measures targeted road-related offenses. Community-oriented work and engagement were prioritized, especially in the densely populated city centre, focusing on road traffic and vulnerable road users. Integrating the apps used by MWS with criminological knowledge supports future planning, implementation, and justification of measures, as well as urban planning. Besides, mutual cooperation and exchange of information between MWS and other stakeholders are key to comprehensive security provision in the local environment. Research Limitations/Implications: A key limitation is that we only analysed repressive and preventive measures conducted by the MWS Ljubljana in 2022. Practical Implications: Applying criminological findings to municipal warden work is effective. Utilizing hot spot displays supports informed decision-making and preventive strategies. In instances where general prevention methods and misdemeanour procedures prove ineffective in ensuring public safety and preventing violations, particularly findings from the field of prevention, community policing and plural policing, can be useful. Originality/Value: This study is pioneering with a unique approach, utilizing new methodologies and perspectives to explain and validate the work of municipal wardens.

The impact of financial and non-financial work incentives on the safety behavior of heavy truck drivers
Sebastjan Škerlič, Vanja Erčulj, 2021, izvirni znanstveni članek

Opis: The goal of the research is to determine how compensation affects the safety behavior of truck drivers and consequently the frequency of traffic accidents. For this purpose, a survey was conducted on a sample of 220 truck drivers in international road transport in the EU, where the results of the Structural Equation Model (SEM) show that in the current state of the transport sector, financial and non-financial incentives have a positive impact on the work and safety behavior of drivers. Financial incentives also have an impact on drivers’ increased perception of their driving ability, while moving violations continue to have a major impact on the number of accidents. The proposed improvements enable decision-makers at the highest level to adopt legal solutions to help manage the issues that have been affecting the industry from a work, social and safety point of view for the past several years. The results of the research therefore represent an important guideline for improvements to the legislature as well as in the systematization of truck driver compensation within companies.
