1. Preverjanje pokritosti tal z uporabo dveh digitalnih orodij : diplomsko deloKristian Lipavšek, 2024, diplomsko delo Opis: Diplomska naloga opisuje preverjanje pokritosti tal z uporabo digitalnih orodij. Namen preverjanja pokritosti tal je, da s pomočjo sodobne tehnologije enostavneje kmetujemo. Digitalni orodji/aplikaciji SoilCover in Refarmo na podlagi zajetih fotografij s terena izračunata procentualno pokritost tal z ostanki posevkov, kamenjem in biomaso. Za lažje razumevanje sta programa opisana in praktično prikazana. Raziskava temelji na terenskih meritvah in statističnih analizah, ki so pokazale, da so določene obdelave tal optimalne za doseganje večje oziroma manjše pokritosti tal. Iz rezultatov lahko zaključimo, da je aplikacija SoilCover prikazala natančnejše podatke, saj so vsi podatki bili izračunani na 2 decimalni številki natančno in celotne fotografije točno določeno obarvane s predstavljeno barvo (kamenje, prst, ostanki rastlin in posevkov), v primerjavi s polavtomatskim izračunom pokritosti tal aplikacije Refarmo, na fotografiji označeni le z eno barvo in pomočjo človeške roke in znanja.

3. Genetska struktura in raznolikost nekaterih tradicionalnih genotipov sliv (Prunus domestica L., Prunus cerasifera Ehrh. in Prunus spinosa L.) : doktorska disertacijaTina Ternjak, 2024, doktorska disertacija Opis: Slovenia has a unique blend of climatic, soil, geographic and historical factors that fostered a rich tradition of plum cultivation and utilization. This study was set up to achieve following objectives: 1. assess the genetic diversity of 124 accessions of the three Prunus species (P. domestica L., P. cerasifera Ehrh., and P. spinosa L.); explore the possible contribution of P. cerasifera and P. spinosa to the ancestry of P. domestica; examine the genetic relationships and variability among the prevalent P. domestica material distributed in Slovenia. A combination of genetic markers, including 11 SSRs (UDP96-005, BPPCT034, EMPAS12, UCD-CH17, EMPAS06, EMPAS11, EMPAS14, BPPCT014, BPPCT025, CPSCT026 and CPPCT006) and three universal cpDNA markers (HK, K1K2 and VL), were chosen alongside flow cytometry. The analysis identified ten cpDNA haplotypes, which were grouped into three clusters using Unweighted Neighbor-Joining (NJ) analysis. All 11 SSR primer pairs exhibited polymorphism, revealing 116 unique genotypes and a total of 328 alleles, indicating considerable diversity with an average of 29.82 alleles per locus. Bayesian analysis distinguished two ancestral populations across all analyzed species. Principal Coordinate Analysis (PCoA) reflected the clustering observed in the Bayesian analysis. When analyzing individual set of P. domestica material, Bayesian analysis also distinguished two ancestral populations across, with PCoA confirming the results of Bayesian analysis. The NJ analysis categorized 71 P. domestica accessions into three clusters with numerous subgroups, reflecting a high genetic diversity. The majority of accessions aligned with traditional pomological groups, such as common prunes, mirabelle plums and greengages.
Genetic diversity parameters were analyzed for the 42 diploid P. cerasifera genotypes. A relatively high diversity levels were found, resulting in 135 alleles, with high average values for alleles per locus (10.38), effective number of alleles (Ne = 5.22), expected heterozygosity (He = 0.77), observed heterozygosity (Ho = 0.64) and PIC value (0.754). In addition, 32 private alleles were found in 20 accessions. Bayesian analysis of the P. cerasifera material revealed three ancestral populations, corroborated by Principal Coordinate Analysis, while an NJ analysis grouped the accessions into three clusters based on the origin of the accession. This study identified valuable local landraces within the P. domestica pool, including traditional prunes or Bluish plums, which are of great genetic interest. Furthermore, the integration of complementary methods facilitated the differentiation of the three species and provided insights into the origin of plum. The findings will be crucial in comprehending the diversity of Slovenian plum germplasm, improving conservation efforts, recovering local genotypes and enriching existing collections of plant genetic resources.

4. Architecture of the health system as an enabler of better wellbeingTimotej Jagrič, Štefan Bojnec, Christine Elisabeth Brown, Vita Jagrič, 2023, izvirni znanstveni članek Opis: ntroduction: Health systems worldwide have heterogenous capacities and financing characteristics. No clear empirical evidence is available on the possible outcomes of these characteristics for population wellbeing.
Aim: The study aims to provide empirical insight into health policy alternatives to support the development of health system architecture to improve population wellbeing.
Method and results: We developed an unsupervised neural network model to cluster countries and used the Human Development Index to derive a wellbeing model. The results show that no single health system architecture is associated with a higher level of population wellbeing. Strikingly, high levels of health expenditure and physical health capacity do not guarantee a high level of population wellbeing and different health systems correspond to a certain wellbeing level.
Conclusions: Our analysis shows that alternative options exist for some health system characteristics. These can be considered by governments developing health policy priorities.

5. Growth and glucosinolate profiles of Eruca sativa (Mill.) (rocket salad) and Diplotaxis tenuifolia (L.) DC. under different LED lighting regimesDenis Stajnko, Peter Berk, Andrej Orgulan, Marko Gomboc, Damijan Kelc, Jurij Rakun, 2022, izvirni znanstveni članek Opis: In this study, the growth and glucosinolate (GSL) profiles of rocket salad Eruca sativa (Mill.) and Diplotaxis tenuifolia (L.) DC. were determined during 30 days growing under different lighting regimes; T5_ peak at 545 nm, LED1_ peak at 631 nm and LED2_ peak at 598 nm. The biggest increase of dry weight (DW) was measured in E. sativa under T5 (0.657 g DW/plant) and the lowest in D. tenuifolia under LED1 (0.080 g DW/plant). GSL content was found to vary significantly, regardless of the light treatment, but it is related with genotype (E. sativa, r = 0.802**). On average, the highest amount of 4-methylsulfinylbutyl-GSL (glucosativin) (7.3248 mg/g DW) was quantified in E. sativa and D. tenuifolia (6.7428 mg/g DW) under the T5. The regression analysis between different light wavelengths and glucosinolates showed the strongest correlation between photosynthetic photon flux density (PPFD_B) and 4-methylthiobutyl-GSL (glucoerucin) in E. sativa (r = 0.698*) and D. tenuifolia (r = 0.693*), respectively, which indicates the effect of light on the response of plants to induced stress and changes in GSL biosynthesis.

6. Possibilities and concerns of implementing precision agriculture technologies on small farms in SloveniaJurij Rakun, Erik Rihter, Damijan Kelc, Denis Stajnko, Peter Vindiš, Peter Berk, Peter Polič, Miran Lakota, 2022, izvirni znanstveni članek Opis: Precision agriculture (PA) through the use and utilization of innovative technologies is a concept in agricultural management that enables long-term efficiency gains, control of unforeseen changes, and a reduction of negative impacts on the environment. However, there are even more reasons and benefits to using precision agriculture technologies (PATs) on farms, but the actual use on small farms is often questionable. The main objective of this research was to evaluate and analyze the current state of PA and its potential on a set of small farms. In addition, a comparison was made between small farms located in less favored areas (LFAs) and more favored areas (MFAs) to find if specific characteristics of the surrounding environment affect the (non-) implementation of these technologies by farm owners, with respect to the given regional possibilities. The result shows that 57.5% of respondents on these farms have never implemented PATs before and 20% are beginners in their respective fields. It was found that there were no statistically significant differences in the integration between fewer LFAs and MFAs technologies and their use in this study. The majority of respondents believe that the main changes need to occur on the level of politics. The results show that the level of cost or initial investment is the main reason and the main obstacle in the implementation of PATs on the surveyed farms.

7. Toward an economy of wellbeing : the economic impact of the Welsh healthcare sectorTimotej Jagrič, Christine Elisabeth Brown, Dušan Fister, Oliver Darlington, Kathryn Ashton, Mariana Dyakova, Mark Bellis, Vita Jagrič, 2022, izvirni znanstveni članek Opis: Population health and wellbeing is both a result, as well as a driver, of economic development and prosperity on global, European, national and sub-national (local) levels. Wales, one of the four United Kingdom (UK) nations, has shown a long-term commitment to sustainable development and achieving prosperity for all, providing a good example of both national and sub-national level, which can be useful for other European countries and regions. In this paper, the economic importance of the healthcare sector to the Welsh economy is explored. We use a large number of data sources for the UK and Welsh economy to derive an economic model for 2017. We estimate output, income, employment, value-added, and import multipliers of the healthcare sector. Results suggest that the healthcare sector has an above average contribution in four explored economic aspects of the Welsh economy (output, income, employment, value-added), according to its impact on the surrounding economic ecosystem. Also, it is below average regarding leaking through imports. The multipliers' values offer empirical evidence when deciding on alternative policy actions. Such actions can be used as a stimulus for encouraging regional development and post-COVID economic recovery. Our study refers to the Welsh healthcare sector's economic impact as a whole. Therefore, we suggest investigating the economic impact of individual healthcare providers in the future.

8. Pravni vidiki informacijske varnosti : magistrsko deloMonika Holešek, 2024, magistrsko delo Opis: Prepričanje, da obstaja zamejen krog pravnih pravil, ki zanesljivo in popolno regulirajo področje informacijske varnosti, je huda zmota. Na tem področju se vrstijo in medsebojno prepletajo najrazličnejši družbeni podsistemi, ki jih je potrebno upoštevati. Hiter razvoj informacijsko-komunikacijskih tehnologij in z njimi povezanih sistemov, s seboj prinaša tudi kar nekaj težav ter vseskozi odpira nove pravne dileme. Živimo v družbi, ki je praktično odvisna od tehnologije. Pravo pa tehnološkemu razvoju težko sledi. Razloga za to sta vsaj dva. Prvi je togost nekaterih klasičnih pravnih institutov in posledična neuporabnost za nove izzive, ki jih prinaša digitalizacija. Drugi problem je, da bi nenehno spreminjanje pravnih pravil ogrozilo pravno varnost. V magistrskem delu je tako na kratko predstavljeno področje informacijske varnosti, s poudarkom na razlogih za reguliranje tega področja. Predstavljeni so nekateri splošni
pravni akti Republike Slovenije in relevantni predpisi Evropske unije. Razvoj tehnologij, kot so umetna inteligenca, internet stvari, robotika in druge informacijsko-komunikacijske tehnologije eksponentno napreduje, kar bo v prihodnosti predstavljajo vedno večji izziv.

9. New suptech tool of the predictive generation for insurance companies : the case of the European marketTimotej Jagrič, Daniel Zdolšek, Robert Horvat, Iztok Kolar, Niko Erker, Jernej Merhar, Vita Jagrič, 2023, izvirni znanstveni članek Opis: Financial innovation, green investments, or climate change are changing insurers’ business ecosystems, impacting their business behaviour and financial vulnerability. Supervisors and other stakeholders are interested in identifying the path toward deterioration in the insurance company’s financial health as early as possible. Suptech tools enable them to discover more and to intervene in a timely manner. We propose an artificial intelligence approach using Kohonen’s self-organizing maps. The dataset used for development and testing included yearly financial statements with 4058 observations for European composite insurance companies from 2012 to 2021. In a novel manner, the model investigates the behaviour of insurers, looking for similarities. The model forms a map. For the obtained groupings of companies from different geographical origins, a common characteristic was discovered regarding their future financial deterioration. A threshold defined using the solvency capital requirement (SCR) ratio being below 130% for the next year is applied to the map. On the test sample, the model correctly identified on average 86% of problematic companies and 79% of unproblematic companies. Changing the SCR ratio level enables differentiation into multiple map sections. The model does not rely on traditional methods, or the use of the SCR ratio as a dependent variable but looks for similarities in the actual insurer’s financial behaviour. The proposed approach offers grounds for a Suptech tool of predictive generation to support early detection of the possible future financial distress of an insurance company.

10. Evropski preiskovalni nalog – razvoj, novosti in njegova uporaba s strani obrambe: izbrani vidiki : magistrsko deloTeodora Kordiš, 2024, magistrsko delo Opis: S povečevanjem števila kaznivih dejanj, ki po svoji razsežnosti presegajo meje ene države, je pridobivanje dokazov iz tujine postal eden izmed ključnih vidikov uspešnega pregona. Čezmejno sodelovanje v kazenskih zadevah se je gradilo postopno. Od sistemov zaprosil, temelječih na Konvenciji o medsebojni pravni pomoči, se je do danes v EU uspel vzpostaviti učinkovit sistem evropskega preiskovalnega naloga, ki združuje tako načelo medsebojne pravne pomoči kot tudi načelo vzajemnega priznavanja. EPN je poenotil in pohitril postopke pridobivanja dokazov iz tujine, ter tako pripomogel k učinkovitejšemu pregonu. Navkljub podrobni ureditvi omenjenega orodja, ostajajo nekatera odprta vprašanje uporabe EPN s strani obrambe. Določbe Direktive 2014/41/EU, v skladu s katero je bil nalog implementiran v države članice, ne dajejo zadostne pravne podlage po kateri bi lahko obramba direktno izdala EPN, brez naknadne potrditve takšne izdaje s strani pravosodnega organa. Dodatno, ni predvidene izrecne pravice do pravnega sredstva za izpodbijanje izdaje ali izvršitve EPN. Določbe direktive ne nalagajo državam članicam obveznost uvedbe drugih pravnih sredstev v postopkih z EPN, razen tistih, ki so po obstoječem nacionalnem redu že na voljo v podobnih domačih primerih. Varstvo in položaj obrambe se, navkljub harmonizaciji z Direktivo 2014/41/EU, precej razlikuje po posameznih državah, saj so dodatne procesne možnosti pri uporabi EPN v prid obrambe na voljo le v državah, ki so te omogočile pri implementaciji omenjene direktive. Čeprav je določen minimalni standard varstva, ki ga dajejo temeljne pravice in svoboščine iz Listine EU in EKČP, tudi za postopke z EPN, so omenjene določbe ohlapne ter dajejo državam članicam velik manevrski prostor, kako izpolniti obveznosti iz teh pravic. Pravica do učinkovitega pravnega sredstva iz EKČP namreč ne daje možnosti izpodbijanja ukrepa predvidenega z EPN pred izvedbo, vendar določa predvsem možnost nekega pravnega sredstva, ki je lahko na voljo tudi kasneje v postopku. V EU se še vedno pojavljajo primeri izdaje in izvršitve EPN v državah, ki ne zagotavljajo niti minimalnega standarda varstva v svojih kazenskih postopkih, zaradi česar je pridobivanje ali posredovanje dokazov na podlagi tako izvedenega EPN lahko vprašljivo. SEU je v zadevi Gavanozov II naredilo korak naprej in izpostavilo pomembnost obstoja pravnega sredstva tudi zoper izdajo EPN v nacionalni zakonodaji posamezne države, da lahko slednja v okviru medsebojnega priznavanja sploh izdaja EPN. Slovenija ob implementaciji ni predvidela posebnih pravnih sredstev v postopkih z EPN. Odsotnost pravic obrambe povezanih z EPN le v delu zapolnjujejo splošne določbe slovenskega kazenskega postopka po ZKP-1. Nasprotno je Italija ob implementaciji določila tudi možnost izpodbijanja potrditve EPN s pravnim sredstvom. Z upoštevanjem dobrih praks držav članic in pravnih ter praktičnih izzivov s katerimi se srečuje obramba, je na voljo še veliko prostora, za ustreznejšo ureditev pravic obrambe v postopkih z EPN v Sloveniji in na ravni EU.
