2. Honey bee colony winter loss rates for 35 countries participating in the COLOSS survey for winter 2018-2019, and the effects of a new queen on the risk of colony winter lossAlison Gray, Aleš Gregorc, 2020, original scientific article Abstract: This article presents managed honey bee colony loss rates over winter 2018/19 resulting from using the standardised COLOSS questionnaire in 35 countries (31 in Europe). In total, 28,629 beekeepers supplying valid loss data wintered 738,233 colonies, and reported 29,912 (4.1%, 95% confidence interval (CI) 4.0%4.1%) colonies with unsolvable queen problems, 79,146 (10.7%, 95% CI 10.5%10.9%) dead colonies after winter and 13,895 colonies (1.9%, 95% CI 1.8%2.0%) lost through natural disaster. This gave an overall colony winter loss rate of 16.7% (95% CI 16.4%16.9%), varying greatly between countries, from 5.8% to 32.0%. We modelled the risk of loss as a dead/empty colony or from unresolvable queen problems, and found that, overall, larger beekeeping operations with more than 150 colonies experienced significantly lower losses (p<0.001), consistent with earlier studies. Additionally, beekeepers included in this survey who did not migrate their colonies at least once in 2018 had significantly lower losses than those migrating (p<0.001). The percentage of new queens from 2018 in wintered colonies was also examined as a potential risk factor. The percentage of colonies going into winter with a new queen was estimated as 55.0% over all countries. Higher percentages of young queens corresponded to lower overall losses (excluding losses from natural disaster), but also lower losses from unresolvable queen problems, and lower losses from winter mortality (p<0.001). Detailed results for each country and overall are given in a table, and a map shows relative risks of winter loss at regional level.

3. Uporaba napredne analitike pri odkrivanju in preprečevanju pranja denarjaAjša Lutar, 2025, undergraduate thesis Abstract: Pranje denarja predstavlja globalni izziv, ki ogroža stabilnost in integriteto finančnega sistema ter spodkopava zaupanje v finančne institucije. Tradicionalni pristopi za preprečevanje pranja denarja, ki temeljijo na vnaprej določenih pravilih, pogosto vodijo do velikega števila lažno pozitivnih opozoril, kar zmanjšuje učinkovitost in povečuje stroške delovanja. Poleg tega vse strožja zakonodaja in regulativne zahteve od finančnih institucij zahtevajo nenehno prilagajanje in izboljševanje nadzornih mehanizmov.
Diplomsko delo se uvodoma osredotoča na predstavitev temeljnih pojmov pranja denarja, njegovih značilnih faz in pojava profesionalnega pranja denarja. Predstavljena je tudi vloga ključnih mednarodnih in nacionalnih organizacij, ki delujejo na področju preprečevanja pranja denarja. V nadaljevanju je opredeljena napredna analitika, pri čemer so predstavljeni različni pristopi, kot so podatkovno rudarjenje, analiza sentimenta, klastrska analiza, strojno učenje, vizualizacija podatkov, analiza časovnih serij in analitika velikih podatkov. Poudarjena je njihova uporaba pri zbiranju podatkov, segmentaciji strank, zaznavanju anomalij, prioritetni obravnavi opozoril in vizualni predstavitvi rezultatov.
Posebna pozornost je namenjena strukturi in delovanju sistemov za preprečevanje pranja denarja. Predstavljeni so ključni izzivi, kot so visoka stopnja lažno pozitivnih zaznav, potreba po kakovostnih podatkih ter zahteve glede skladnosti z zakonodajo. Obravnavane so tudi ovire pri vključevanju napredne analitike v finančne institucije.
V drugem delu je predstavljen trg tehnoloških rešitev za preprečevanje pranja denarja, s posebnim poudarkom na podjetju NICE Actimize kot vodilnem ponudniku. Podrobneje je opisana rešitev NICE Actimize Suspicious Activity Monitoring.

4. Pregled uporabe "zelenih logističnih shem" v mestih v Evropski Uniji in predlog za mesto MariborMarko Murko, 2025, undergraduate thesis Abstract: V diplomskem delu smo želeli opozoriti na problematiko onesnaženosti zraka v mestu Maribor in nekaterih drugih evropskih mestih. Onesnaženost zraka je velik problem, saj zelo nevarno vpliva na zdravje. Poiskali smo glavne vire onesnaževanja ter raziskali, kako poteka monitoring in spremljanje onesnaženja zraka v Mariboru. Preverili smo obstoječe stanje onesnaženosti zraka v mestu Maribor ter rezultate kritično analizirali. Analizirali smo 5 evropskih mest, ki uporabljajo zelene logistične sheme, italijanska Padova, avstrijski Gradec, francoski Pays de Romans – ta so se dokazala v sklopu projekta CO2NeuTrAlp – ter danski Kopenhagen in švedski Stockholm, ki se že leta uvrščata visoko na lestvici Green City Index oz. Arcadian Sustainable Citiy Index, ki se uporablja v preteklih letih. Preučili smo trenutne rešitve izbranih mest ter tako skušali poiskati trajnostno pot, izboljšave ter nadgradnje, ki bi jih lahko uporabili v mestu Maribor. Na koncu naloge smo podali konstruktiven predlog za mesto Maribor, in sicer na kakšen način bi lahko z zelenimi logističnimi shemami še bolj pripomogli k zmanjšanju onesnaženosti zraka

6. Maintenance management of a transmission substation with optimizationPeter Kitak, Lovro Belak, Jože Pihler, Janez Ribič, 2021, original scientific article Abstract: The paper deals with the reliability-centered maintenance (RCM) of a transmission substation. The process of the planning and actual performance of maintenance was carried out using an
optimization algorithm. This maintenance procedure represents the maintenance management and
included reliability of the power system operation, maintenance costs, and associated risks. The originality of the paper lies in the integrated treatment of all maintenance processes that are included in
the pre-processing and used in the optimization process for reliability-centered maintenance. The optimization algorithm of transmission substation maintenance was tested in practice on the equipment
and components of an existing 400/110–220/110 kV substation in the Slovenian electricity transmission system. A comparison analysis was also carried out of the past time-based maintenance (TBM)
and the new reliability-centered maintenance (RCM), on the basis of the optimization algorithm.
Keywords: reliability-centered maintenance, optimization, transmission substation, condition monitoring

7. Chemical analysis of thermally aged cables in nuclear power plantsMarko Pirc, Jurij Avsec, Dijana Vrsaljko, 2025, original scientific article Abstract: The paper presents findings on the implementation of various mechanical and chemical diagnostic procedures aimed at enhancing the monitoring of cable insulation conditions in Krško Nuclear Power Plant (NEK). This article introduces the advancement of four novel diagnostic testing methodologies for evaluating the mechanical and chemical properties of cable insulation: Indenter Modulus (IM), Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric analysis (TGA) and X-Ray Fluorescence Spectral Analysis (XRF). Experiments were performed on diverse samples of widely used nuclear-qualified cable polymer materials, including Ethylene Propylene Rubber (EPR) and Crosslinked Polyethylene (XLPE), all with a Chlorosulphonated Polyethylene (CSPE) jacket. Samples from various vintages were subjected to additional temperature ageing in many stages, to establish field testing acceptability requirements and assess the remaining lifespan of the polymer insulation. Diagnostic tests were performed and some preliminary results are reported.
Keywords: cable, ageing, nuclear, diagnostic testing criteria, chemical condition monitoring

8. Structural monitoring and integrity of masonry buildings in Slovenia : Mojmir UranjekMojmir Uranjek, 2024, original scientific article Abstract: It is estimated that older reinforced buildings represent almost 50% of the total number of existing buildings in Slovenia. It is further estimated that 1/3 of the population of Slovenia lives in areas where the PGA is 0.2g or more. Seismic resistance of such buildings in general is not sufficient and appropriate measures should be implemented. It is recommended that these are designed incorporating the findings of structural monitoring based on which useful information can be obtained. Structural monitoring aims to monitor the possible advancement of existing or formation of new damage due to various reasons, while strengthening measures aim to ensure structural integrity and adequate level of seismic resistance of building. The article describes the current practice in this field in Slovenia through practical examples. Additionally, suggestions that could help improve the current approach such as combining the global calculation model with local failure mechanisms and combining the activities of monitoring, investigations of structure and assessing seismic resistance are given. Usage of emerging technologies that are non-invasive both in monitoring, as well as investigation of structure is encouraged. It is recommended that reversible strengthening measures especially in the case of heritage buildings are used.

9. School-based exercise programs for promoting cardiorespiratory fitness in overweight and obese children aged 6 to 10Stefan Mijalković, Dušan Stanković, Mario Tomljanović, Maja Batez, Maki Grle, Ivana Grle, Ivan Brkljačić, Josip Jularić, Goran Sporiš, Suzana Žilič Fišer, 2022, review article Abstract: The aim of this study was to conduct a systematic review of the school-based exercise
programs for promoting cardiorespiratory fitness in overweight and obese children aged 6 to 10.
Electronic databases (Web of Science and PubMed) were used as searching tools for collecting
adequate studies published in the past 20 years. A total of 13 studies met the criteria for inclusion in
this review, with a total of 2810 participants, both male and female. According to the results of this
systematic review, overweight and obese children aged 6 to 10 who underwent certain interventions
had their CRF improved. Furthermore, evidence suggested that interventions carried out during
a longer period of time suggested led to greater improvement of cardiorespiratory fitness than
a shorter one, but the level of cardiorespiratory fitness gradually decreases after the intervention.
