1. What is the relationship between sales growth and insolvency risk?Nataša Šarlija, Sanja Šimić, Biljana Đanković, 2023, izvirni znanstveni članek Opis: Sales growth is essential for an enterprise’s survival and financial growth.
If an enterprise manages to achieve sales growth, its expansion can be
accomplished. However, does sales growth always have only positive effects?
If the enterprise is not collecting enough cash, it can miss a payment on its
debt, triggering a series of events that can lead to its insolvency. The goal
of the paper is to explore the relationship between an enterprise's sales
growth and its insolvency. The relationship is tested empirically on the data
set of 4271 SMEs in Croatia. The results confirmed that there is a relationship
between sales growth and insolvency. Better indicators exist with solvent and
growing SMEs than with insolvent and non-growing. Results have also shown
that high growth can be at the same time a high risk. The paper contributes
to a deeper understanding of the relationship between sales growth and
insolvency and empirically demonstrates that sales growth over 200% per
year induces the highest probability of insolvency compared to other lower
levels of growth.

2. Unraveling the antibiofilm activity of a new nanogold resin for dentures and epithesisVera Ivanović, Danica Popović Antić, Sanja Petrović, Rebeka Rudolf, Peter Majerič, Miloš Lazarević, Igor Djordjević, Vojkan Lazić, Milena Radunović, 2022, izvirni znanstveni članek Opis: Dentures and epitheses are mostly made from poly(methyl methacrylate) (PMMA), which
does not show antimicrobial properties. They present reservoirs of microorganisms grown in
biofilms. The aim of this study is to prepare a PMMA enriched with gold nanoparticles (AuNPs)-
PMMA/AuNPs and the examination of its physical, mechanical and antimicrobial properties. The
AuNPS were synthetized from HAuCl4 using the ultrasonic spray pyrolysis method with lyophilization. The PMMA/AuNP samples were compared to PMMA samples. Density was measured by
pycnometer. Microhardness was evaluated using the Vickers hardness test. Monomicrobial biofilm
formation (Streptococcus mitis, Candida albicans, Staphylococcus aureus and Escherichia coli) was measured by colony-forming units (CFUs) and MTT test and visualized by SEM. AuNP release was
measured indirectly (the CFUs of the medium around the sample). The density and microhardness
of the PMMA/AuNPs were similar to those of the PMMA. CFU and MTT values for the biofilms
formed on the PMMA for each of the tested species were higher than those of the biofilms formed on
the PMMA/AuNPs. The CFUs of the medium around the sample were similar for both materials.
PMMA/AuNPs showed a significant reduction in the monomicrobial biofilms of all tested species.
AuNPs are not released from PMMA/AuNPs. Density, indirect measurement of residual monomer
and dentures weight were similar between PMMA and PMMA/AuNPs. Microhardness, as a measure
of the wear resistance, was also similar between tested discs.
Ključne besede: PMMA, gold nanoparticles (AuNPs), biofilm, antibiofilm effect

4. The difference of managerial approach in more or less design-oriented companiesSanja Rocco, Aleksandra Pisnik, 2020, izvirni znanstveni članek Opis: While the market orientation of companies has been thoroughly analysed, a review of the marketing literature indicates that there is significantly less research on Design Orientation, and especially on their relationship. This paper analyzes the variables of Design and Market Orientation on the basis of existing models and develops the measurement instrument for future research. The study also investigates the impact of managerial approach on the exploitation of design resources in the company. Two hypotheses are developed: the first on the DO-MO relationship, acknowledging the multiple dimensions of Design Orientation and the second on the difference in managerial approach between more and less design-oriented companies. The first, qualitative stage of the research served to re-examine the research constructs and variables, while an Internet survey was used in the second, quantitative stage, among managers and CEOs from Croatian companies. The design dimensions in our final model represented intermediaries between Market Orientation, managerial approach, and market outcomes. Results confirm that managers in non-design oriented companies differ from those in design-oriented companies by perceived design value. Managers’ and CEOs’ awareness of design, its value and potentials, are of great importance for design implementation and Design Orientation of a company as a whole, especially in SMEs. Managerial approach, according to results, has a direct effect on Design Orientation, but it also influences Market Orientation, both directly and indirectly, as well as business success. Findings of this study can have implications for scholars, as well as for managers in practice, especially in emerging economies, which lack research in Design Orientation. Future research should be expanded to other countries in the region.

5. Valorization of biomass through anaerobic digestion and hydrothermal carbonization : integrated process flowsheet and supply chain network optimizationSanja Potrč, Aleksandra Petrovič, Jafaru Musa Egieya, Lidija Čuček, 2025, izvirni znanstveni članek Opis: Utilization of biomass through anaerobic digestion and hydrothermal carbonization is crucial to maximize resource efficiency. At the same time, supply chain integration ensures sustainable feedstock management and minimizes environmental and logistical impacts, enabling a holistic approach to a circular bioeconomy. This study presents an integrated approach to simultaneously optimize the biomass supply chain network and process flowsheet, which includes anaerobic digestion, cogeneration, and hydrothermal carbonization. A three-layer supply chain network superstructure was hence developed to integrate the optimization of process variables with supply chain features such as transportation modes, feedstock supply, plant location, and demand location. A mixed-integer nonlinear programming model aimed at maximizing the economic performance of the system was formulated and applied to a case study of selected regions in Slovenia. The results show a great potential for the utilization of organic biomass with an annual after tax profit of 23.13 million USD per year, with the production of 245.70 GWh/yr of electricity, 298.83 GWh/yr of heat, and 185.08 kt/yr of hydrochar. The optimal configuration of the supply chain network, including the selection of supply zones, plant locations and demand locations, transportation links, and mode of transportation is presented, along with the optimal process variables within the plant.

6. International energy security risk index - analysis of the methodological settingsIztok Podbregar, Goran Šimić, Mirjana Radovanović, Sanja Filipović, Polona Šprajc, 2020, izvirni znanstveni članek Opis: The main objective of this paper is to analyze model settings of the International Energy Security Risk Index developed by the U.S. Chamber of Commerce. The study was performed using stepwise regression, principal component analysis, and Promax oblique rotation. The conclusion of the regression analysis shows that Crude Oil Price and Global Coal Reserves are sufficient to explain 90% of the variance of the Index. However, if a model that explains 100% of the variance of the Index is chosen and other variables are added, Global Coal Reserves loses importance due to the presence of other parameters in which it is contained. Regardless of the chosen model of analysis, it is evident that there is room for revising the Index and removing variables that do not contribute to its precision. The research showed that the main disadvantage of the variables that make up the Index rests with the fact that the variables are of different degrees of generality, that is, one parameter is contained in other parameters (unclear which other). The research covers data for 25 countries over a 26-year period, with the first year of the research being 1980 and the last 2016 (the latest available report).

7. The international energy security risk index in sustainable energy and economy transition decision making - a reliability analysisIztok Podbregar, Goran Šimić, Mirjana Radovanović, Sanja Filipović, Damjan Maletič, Polona Šprajc, 2020, izvirni znanstveni članek Opis: The world economy and society are in a complex process of transition characterized by a high degree of uncertainty. Therefore, further development and management of the transition will largely depend on the quality of the decisions made and, accordingly, on the decision-making process itself. The main goal of this study is to analyze the reliability of International Energy Security Risk Index as a tool to support the process of energy and economy transition decision making, as closely related and highly interdependent phenomena. The index is composed of 29 aggregated variables (grouped into eight categories), and the research is conducted on a research sample of 25 countries over a period of 36 years. The reliability assessment is performed by using Multiple Regression Analysis. Multicollinearity test, plus Multicollinearity test with Variance Inflation Factors, is used for methodological verification. The test results indicate a high degree of unreliability of the Index, as is concluded based on the observed errors in its methodological settings. These errors primarily relate to a high degree of multicollinearity in all 29 variables, whereby independent variables lose their independence and thus jeopardize reliability of the total Index. Out of the eight groups of variables, the fuel imports group is the only one that does not show big methodological errors. The paper presents a recommendation for the improvement of the observed Index (review of the role of individual variables found to be particularly methodologically indicative), as well as a recommendation for different distribution of weighting coefficients.

8. Clostridioides difficile ribotype distribution in a large teaching hospital in SerbiaMiloš Korać, Maja Rupnik, Nataša Nikolić, Milica Jovanović, Tanja Tošić, Jovan Malinić, Nikola Mitrović, Marko Marković, Ankica Vujović, Sanja Peruničić, Ksenija Bojović, Vladimir V. Đorđević, Aleksandra Barać, Ivana Milošević, 2020, izvirni znanstveni članek Opis: Background: The global epidemic of nosocomial diarrhea caused by Clostridioides (Clostridium) difficile started in 2000, with high mortality rates and emergence of a new hypervirulent strain NAP1/BI/027. The aim of this study was to assess the presence of ribotype 027 and other C. difficile ribotypes in a Serbian University Hospital, compare the temporal variability of ribotypes 3 years apart, as well as to compare clinical, demographic and laboratory characteristics and disease outcome among patients infected with 027 and non-027 ribotype. This was a prospective observational cohort study addressing 4-month intervals during 2014/2015 and 2017/2018.
Results: Ribotyping was performed in 64 non-duplicate C. difficile strains. Ribotype 027 was the most prevalent, and was detected in 53 (82.8%) patients (43/45 and 10/19 patients in 2014-2015 and 2017/2018, respectively). Other detected ribotypes were 001/072 in 4 (6.3%), 002 in 4 (6.3%), 014/020 in 2 (3.1%) and 176 in 1 (1.5%) patient. The percentage of the patients infected with ribotype 027 significantly decreased during the 3-year period, from 95.6 to 52.6% (p < 0.001). Ribotype 027 infection was associated with fluoroquinolone treatment more frequently than infection with other ribotypes [33 (62.3%) vs. 2 (18.2%), p = 0.010)]. A severe C. difficile infection was diagnosed more often in patients with the detected ribotype 027 compared to those infected with non-027 ribotypes (p = 0.006). No significant difference in the mortality and recurrence rates was found between the patients infected with ribotype 027 and those infected with other ribotypes [10/53 (18.8%) vs. 2/11 (18.2%), p = 0.708, and 10/35 (28.6%) vs. 0/2 (0%), p = 1.000, respectively].
Conclusion: Clostridium difficile ribotype 027 was the most prevalent ribotype among patients in a large Serbian hospital, but there is a clear decreasing trend.

9. Vpliv čustvene inteligence na zavzetost zaposlenihSanja Đukić, 2024, magistrsko delo Opis: V sodobnem delovnem okolju, v katerem čustva in medosebni odnosi igrajo vse pomembnejšo vlogo, postajajo osebne lastnosti in veščine ključne za oblikovanje delovne zavzetosti. Ena izmed pomembnejših kompetenc prihodnosti je čustvena inteligenca. Odkar umetna inteligenca prevzema vse več analitičnih in ponavljajočih se nalog, postajata čustvena inteligenca in zavzetost ključni za ohranjanje človeške vrednosti v delovnem okolju. Čustvena inteligenca omogoča učinkovito sodelovanje, prilagajanje spremembam, sproščenost pri delu ter vodenje z integriteto in posluhom za zaposlene, česar umetna inteligenca ne more nadomestiti. Zavzetost spodbuja motivacijo, odgovornost in kreativnost, ki so potrebne za inovacije in napredek v organizacijah, v katerih tehnologija sama ne more doseči enakega vpliva. V raziskavi smo preučevali vpliv čustvene inteligence na zavzetost zaposlenih v sodobnem slovenskem delovnem okolju. Uporabili smo vprašalnika UWES-9 za merjenje zavzetosti in WLEIS za merjenje čustvene inteligence, pri čemer je sodelovalo 215 anketirancev. Podatke smo obdelali s programsko opremo IBM SPSS 29, dodatno pa smo izvedli intervju z go. Urško Gerbajs, strokovnjakinjo na področju čustvene inteligence. Raziskava je pokazala, da zaposleni, ki so se udeležili usposabljanj s področja čustvene inteligence, izkazujejo višjo raven te kompetence v primerjavi s tistimi, ki usposabljanj niso obiskali. Prav tako so podjetja, v katerih delodajalci aktivno spodbujajo razvoj čustvene inteligence, dosegla višjo raven zavzetosti med zaposlenimi. Vodstveni kadri so pokazali višje vrednosti zavzetosti v primerjavi z ostalimi. Ugotovitve poudarjajo pomen spodbujanja čustvene inteligence v organizacijah, saj to prispeva k večji delovni zavzetosti in boljšim poslovnim rezultatom. Priporočamo izvedbo empiričnih raziskav v slovenskih podjetjih, da bi pridobili konkretne dokaze o učinkovitosti usposabljanj na področju čustvene inteligence in spodbudili podjetja k večjemu vlaganju v razvoj kadra.
Ključne besede: čustvena inteligenca, zavzetost, razvoj kadra, kompetence prihodnosti

10. Od znamčenja do oblikovanja celostne grafične podobe na primeru neobstoječega podjetja : diplomsko deloSanja Ekart, 2024, diplomsko delo Opis: V diplomskem delu preučujemo proces ustanovitve novega podjetja in nato oblikovanje celostne grafične podobe. Oblikovati celostno grafično podobo za obstoječe podjetje je drugače kot podjetje ustvariti − popolnoma interpretirati, v smislu ustvarjanja imena, identitete, vizije ipd. Dobro celostno grafično podobo lahko ustvarimo le, če organizacijo res razumemo v smislu razumevanja njene filozofije in vizije. Zato se bomo mi poglobili v samo srce organizacije, kar nam bo pomagalo ustvari učinkovito celostno grafično podobo. S pomočjo metode preučevanja informacij bomo raziskovali teoretične vidike blagovne znamke, v smislu kaj je in ustvarjanje le-te. Poglobili se bomo v identiteto podjetja in imidža. Praktični del vsebuje primer na našem neobstoječem podjetju in smernice za ustvarjanje vizualne identitete podjetja. V praktičnem delu smo proces ustvarjanja celostne grafične podobe še realizirali.
Ključne besede: znamčenje, blagovna znamka, identiteta in imidž znamke, celostna grafična podoba, logotip.
