The influence of ethical management behaviour on strengthening the trust of employees in a public kindergarten
Full text linkV magistrskem delu preučujemo pomen etičnega vedenja managementa v javnem vrtcu ter njegovo povezanost z zaupanjem zaposlenih. Etični management vzgojno-izobraževalnih ustanov je posebej občutljivo področje, saj so odločitve vodstva tesno povezane s strokovnim delom vrtca, dobrobitjo otrok, kakovostjo dela strokovnih delavcev in pričakovanji staršev. V teoretičnem delu smo najprej opredelili temeljne pojme etike, organizacijske etike in etičnega managementa ter predstavili njihove posebnosti v javnem sektorju. Poseben poudarek namenimo etičnim načelom, ki usmerjajo ravnanje vodij v vrtcih – pravičnosti, poštenosti, odgovornosti, spoštovanju in skrbnosti – ter vlogi organizacijske kulture pri oblikovanju etično ustreznega vedenja. Sledi obravnava pomena zaupanja kot temeljnega elementa odnosov med zaposlenimi. Zaupanje se krepi skozi pravično obravnavo, transparentno odločanje, vključevanje zaposlenih v procese ter dosledno upoštevanje etičnih standardov. Raziskave poudarjajo, da etično vodstvo vpliva na višjo motivacijo zaposlenih, boljše sodelovanje in večjo povezanost s poslanstvom organizacije, medtem ko neetično ravnanje vodi v izgubo zaupanja, konflikte in zmanjšano kakovost dela. Empirični del temelji na raziskavi, izvedeni med zaposlenimi v izbranem javnem vrtcu. Rezultati raziskave kažejo, da zaposleni vodstvo dojemajo kot etično, spoštljivo in pravično, kar se odraža v visoki stopnji zaupanja ter pozitivnem delovnem vzdušju. Najvišje ocene so prejela področja – odprta komunikacija, poslušanje ter medsebojno zaupanje med zaposlenimi. Pri analizi po skupinah z različno delovno dobo so ugotovljene razlike pri zaznavanju transparentnosti odločanja in razporejanja nalog. Zaposleni so kot ključne dejavnike zaupanja izpostavili odprto komunikacijo, jasno razlago odločitev ter dosledno upoštevanje dogovorjenih pravil. Na podlagi rezultatov raziskave, smo oblikovali tudi možna priporočila za krepitev etičnega vodenja v vrtcu, med katerimi izstopajo večja vključenost zaposlenih v odločanje, povečanje obsega, etična usposabljanja ter krepitev notranjih mehanizmov za obravnavo etičnih dilem. Delo tako prispeva k boljšemu razumevanju pomena etičnega managementa v javnih vrtcih in ponuja usmeritve za nadaljnji razvoj zaupanja ter etične organizacijske kulture.In this master’s thesis, we examine the importance of ethical conduct among management in a public kindergarten and its connection to employees’ trust. Ethical management in educational institutions is a particularly sensitive area, as leadership decisions are closely linked to the kindergarten’s professional work, children’s well-being, the quality of the professional staff’s performance, and parents’ expectations. In the theoretical part, we first define the fundamental concepts of ethics, organizational ethics, and ethical management, and present their specific characteristics in the public sector. Special emphasis is placed on the ethical principles that guide leaders’ behaviour in kindergartens—fairness, honesty, responsibility, respect, and care—and on the role of organizational culture in shaping ethically appropriate behaviour. This is followed by an examination of the significance of trust as a fundamental element of relationships among employees. Trust is strengthened through fair treatment, transparent decision-making, employee involvement in processes, and consistent adherence to ethical standards. Research highlights that ethical leadership promotes higher employee motivation, better cooperation, and stronger alignment with the organization’s mission, whereas unethical conduct leads to a loss of trust, conflicts, and reduced work quality. The empirical part is based on a study conducted among employees in a selected public kindergarten. The results show that employees perceive the leadership as ethical, respectful, and fair, which is reflected in a high level of trust and a positive working atmosphere. Open communication, attentive listening, and mutual trust among employees received the highest evaluations. An analysis of groups with varying lengths of service revealed differences in the perception of decision-making transparency and task allocation. Employees identified open communication, clear explanations of decisions, and consistent adherence to agreed rules as key factors of trust. Based on the research findings, we also formulated recommendations for strengthening ethical leadership in the kindergarten, including greater employee involvement in decision-making, an increased scope of ethical training, and the reinforcement of internal mechanisms for addressing ethical dilemmas. The thesis thus contributes to a better understanding of the significance of ethical management in public kindergartens and offers guidance for the further development of trust and an ethical organizational culture
Development and application of computational chemistry methods for designing COVID-19 therapeutics
Full text linkTekom doktorske disertacije smo se osredotočili na razvoj in uporabo metod računalniške kemije za optimizacijo delovnega toka razvoja zdravilnih učinkovin. V nalogi smo na aplikacijski tematiki SARS-CoV-2 optimizirali načrtovanje knjižnic virtualnih spojin, uporabo molekularnih filtrov za usmeritev kemijskega prostora, uporabo in primerjavo različnih metod izračuna proste vezavne energije ter razvili metodo za kombinatorično in silico mutagenezo in ovrednotenje vezavnega mesta proteinov. Pridobljeno znanje in razvite metode smo aplikativno uporabili za odkritje in vitro zaviralca SARS-CoV-2 proteaze.
V prvem delu smo se poglobili v kritično vrednotenje komercialnih molekularnih knjižnic, s poudarkom na tarčnih knjižnicah usmerjenih proti SARS-CoV-2 ter knjižnicah osredotočenih na zaviralce proteaz in zaviralce protein-proteinskih interakcij. Prišli smo do zaključka, da so tarčne knjižnice v veliki večini primerov pripravljene neustrezno, saj ne navajajo primarne literature, nimajo opisanega protokola sidranja kadar je ta uporabljen, niti programske opreme za sidranje ter imajo kljub uporabi molekularih filtrov prisotne spojine, ki niso zaželene. Optimizirali smo tudi protokol za ustrezno pripravo tarčne molekularne knjižnice.
V drugem delu doktorske disertacije smo se osredotočili na temeljit popis in odprtokodno implementacijo obstoječih molekularnih filtrov v farmacevtski kemiji. Ugotovili smo, da s pomočjo molekularnih filtrov enostavno prilagodimo kemijski prostor, manjše končno število filtrirane knjižnice pripravljenih spojin, pa vodi v učinkovito uporabo računskega časa ob aplikaciji nadaljnjih bolj zahtevnih računalniških metod.
V tretjem delu smo s pomočjo simulacij molekularne dinamike (MD) in izračuna proste energije z metodama MM/GBSA ter BAR, raziskali interakcije ter vpliv mutacij protitelesa tipa IgG na vezavo z različnimi receptorji Fcγ (FcγR). Pridobljeni rezultati vezavne afinitete MM/GBSA in BAR med različnimi FcγR ob vezavi se dobro ujemajo z literaturnimi in vitro podatki, kar kaže na visoko uporabnost razvitih metod. Dodano vrednost pa nosijo na novo odkrite interakcije Fab regije z FcγR, ki so bile kasneje neodvisno dokazane v in vitro poskusih.
V četrtem delu doktorske disertacije smo dopolnili obstoječe delo na prosto dostopnih molekularnih filtrov z implementacijo dodatnih molekularnih filtrov in proučevanjem vpliva vseh implementiranih na reprezentativni nabor 100.000 molekul. Ocenili smo vpliv na kemijski prostor in stopnjo retencije molekul za posamezen filter. Pridobljeni rezultati in posodobitev prosto-dostopnega modela dobro doplonjuje obstoječe znanje.
V petem delu doktorske disertacije smo izvedli bioinformacijsko analizo skrb vzbujajočih virusnih variant SARS-CoV-2. Da bi razumeli mehanizem večje infektivnosti virusnih variant smo izvedli obsežno in silico mutagenezno študijo vezavne površine RBD-ACE2 ter ocenili spremembo vezavne energije s programom FoldX. Za identificirano varianto z večjo vezavo energijo N501Y smo s pomočjo molekularne dinamike potrdili večjo stabilnost kompleksa RBD-ACE2 hkrati pa dobili vpogled v mutirano interakcijsko površino.
V šestem delu smo s pomočjo celovitega pristopa, ki je zajemal pripravo tarčne knjižnice, molekularno sidranje, in vitro biološke teste in simulacije molekularne dinamike identificirali potencialne zaviralce SARS-CoV-2 papainu podobne proteaze (PLpro). Identificirana spojina 372 je pokazala obetavne inhibitorne lastnosti proti PLpro z vrednostjo IC50 82 ± 34 μM. Izvedli smo tudi izračune proste vezavne energije z metodama TI ter LIE, ki sta potrdili in vitro teste in kažeta na uporabnost uporabljenih metod pri ovrednotenju potencialnih učinkovin.
V sedmem delu doktorske disertacije smo uporabo metod računalniške kemije razširili na optimizacijo čiščenja protiteles. S pomočjo molekulskega sidranja smo kombinatorično knjižnico tetrapeptidov sidrali na Fc regijo protiteles in iskali vezavne motive, ki bi lahko posnemali protein A. Najdeni tetrapeIn this doctoral dissertation, we focused on the development and application of computational chemistry methods for optimizing the drug discovery workflow. Using the application topic of SARS-CoV-2, we optimized the design of virtual compound libraries, the use of molecular filters to direct chemical space, compared various methods for calculating binding free energy, and developed a method for combinatorial in silico mutagenesis and evaluation of protein binding sites. The acquired knowledge and developed methods were applied to discover an in vitro inhibitor of the SARS-CoV-2 protease.
In the first part, we critically evaluated commercial molecular libraries, with a focus on targeted libraries directed against SARS-CoV-2 and libraries focused on protease inhibitors and inhibitors of protein-protein interactions. We concluded that most targeted libraries are poorly prepared—they often lack references to primary literature, fail to describe the docking protocol (when used), omit the software used, and contain undesirable compounds despite the use of molecular filters. We also optimized a protocol for properly preparing targeted molecular libraries.
In the second part of the dissertation, we focused on a thorough review and open-source implementation of existing molecular filters in pharmaceutical chemistry. We found that molecular filters can easily tailor chemical space, and a smaller final number of filtered, prepared compounds leads to more efficient computational time usage when applying more advanced computational methods.
In the third part, we used molecular dynamics (MD) simulations and binding free energy calculations via MM/GBSA and BAR methods to investigate the interactions and effects of IgG-type antibody mutations on binding to various Fcγ receptors (FcγR). The obtained MM/GBSA and BAR binding affinity results between different FcγR complexes align well with in vitro literature data, demonstrating the high utility of the developed methods. An added value is the newly discovered Fab-region interactions with FcγR, which were later independently validated in in vitro experiments.
In the fourth part of the doctoral dissertation, we supplemented the existing work on open-access molecular filters by implementing additional filters and studying the impact of all implemented ones on a representative set of 100,000 molecules. We evaluated the effect on the chemical space and the retention rate of molecules for each individual filter. The obtained results and the update of the open-access model significantly complement existing knowledge.
In the fifth part, we conducted a bioinformatic analysis of concerning SARS-CoV-2 viral variants. To understand the mechanism of increased infectivity, we performed an extensive in silico mutagenesis study of the RBD-ACE2 binding surface and estimated binding energy changes using FoldX. For the identified N501Y variant, which showed increased binding energy, molecular dynamics confirmed greater RBD-ACE2 complex stability and provided insight into the mutated interaction surface.
In the sixth part, we used a comprehensive approach—targeted library preparation, molecular docking, in vitro biological testing, and molecular dynamics simulations—to identify potential inhibitors of the SARS-CoV-2 papain-like protease (PLpro). The identified compound 372 showed promising inhibitory activity against PLpro with an IC50 value of 82 ± 34 μM. We also performed free binding energy calculations using TI and LIE methods, which confirmed the in vitro results and demonstrated the applicability of the employed methods for evaluating potential active compounds.
In the seventh part, we extended the application of computational chemistry methods to the optimization of antibody purification. Using molecular docking, we docked a combinatorial library of tetrapeptides to the Fc region of antibodies, searching for binding motifs that could mimic protein A. The identified tetrapeptide motif GSVW showed the best bi
Metoda generiranja preizkusov glede na sysml specifikacije
No full textIn the rapidly improving system design environment there is a need for automatization of tasks which are manual labor intensive. One of the core principles of systems engineering is verification and validation which is present iteratively throughout the development and on a higher system level at the end. For these verification and validation tasks test cases are used. The goal of this thesis is to extract the required test cases from the already present system models, mainly the test cases from function diagrams which are linear and cannot be extracted through state machine diagrams.V trenutnem tehnološko naprednem svetu se področje inženiringa pomika z veliko hitrostjo. Eno on najbolj pomembnih pristopov za snovanje in vzdrževanje velikih, kompleksnih sistemov je sistemski inženiring. S pomočjo definicije zahtev za naš sistem lahko oblikujemo pisno ali vizualno dokumentacijo, ki pripomore k lažjemu razumevanju sistema, ki ga snujemo. Proces sistemskega inženirstva lahko predstavimo s pomočjo V-modela. Snovanje sistema sodi na levi krak V-modela, sledi mu dolina, ki predstavlja implementacijo, in na desnem kraku modela je preizkušanje ustreznosti rešitev. Fokus te naloge bo drugi krak, bolj podrobno verifikacija in validacija sistemskega modela.
S pomočjo modelarskega jezika SysML je možno ustvariti dokumentacijo, ki definira celoten sistem s pomočjo vizualnih objektov, kot so diagrami. Ker je jezik SysML standardiziran s strani organizacije OMG (Object Management Group), se lahko uporablja v različnih programskih okoljih, kar pomeni da se metoda, omenjena v tej nalogi, ne navezuje samo na orodje PTC Winchill Modeler.
Na področju avtomatizacije postopkov sistemskega inženiringa je pri podjetju AVL že nekaj rešitev. Za izvoz in uvoz testnih primerov iz orodja Integirty Lifecycle Manager se uporablja skripta, ki zmanjša potreben čas in trud. Avtomatsko generira datoteke, ki se uporabljajo na testnih postajah, rezultat testov pa ponovno avtomatsko uvozi v programsko okolje.
V sklopu izboljšav je tudi skupek pristopov, ki izboljšajo efektivnost in zmanjšajo potreben čas. Eden izmed teh je polformalni zapis zahtev, ki ga lahko prebere tudi računalnik. Kot predhodnik trenutne naloge je bila programska rešitev, s katero se lahko izvozijo testni primeri, ampak samo iz sistemskega diagrama stanj.
Najprej je bilo treba definirati obseg dela, ki je zavzemal dva različna testna primera od predhodnega projekta. S pomočjo teh dveh primerov bo možno ustvariti program, ki bo lahko operiral z različnimi testnimi primeri. Ker je za avtomatsko generiranje potrebno več podatkov kot prejšnjič, je bilo treba raziskati nov pristop modeliranja. Pristop, ki je bil najbolj primeren, je bila uporaba sekvenčnega diagrama, ki je prikazal točen potek korakov in tudi zavzemal vse potrebne informacije signalov.
V diagram je bilo treba vključiti označbe, ki jih lahko program uporabi za pravilno formiranje testnih primerov. Testni primer je razdeljen na več delov: predpogoj, testni postopek, kriterij in sledeči pogoj. Prvi del je predpogoj, ki bo definiran v posebnem diagramu, saj v realni aplikaciji ne bo samo en testni primer v enem diagramu, kar bi povzročilo zmešnjavo. Predpogoji so označeni s komentarjem s posebno obliko in povezavo do diagrama predpogojev. Naslednje so označene dejavnosti testnega inženirja med testom ali druge stvari, ki delujejo na testni objekt. Te so označene s komentarji in zaporednimi števili. Testni kriterij pa določa, kaj dejansko se mora preveriti med tem testom. Teh kriterijev je lahko več, imajo tudi dva tipa, ki določata, kako bo program te kriterije izvozil.
Prvi tip je pogoj pravilnega zaporedja pošiljanja signalov, drugi pa je pogoj oblike določenega sporočila. Prvi tip je označen s komentarjem, drugi pa se avtomatsko prebere, če ima sporočilo besedilo. Glede na uspešnost testnega primera pa je v diagramu tudi odločitev, ki pove, kaj se zgodi, če je test uspešen ali neuspešen.
S pripravljenima primeroma je bilo možno napisati program, ki bo te informacije izvlekel. Ker je za modeliranje sistema uporabljen program Windchill Modeler, je bilo treba izbrati dostop do okolja, ki ga ponuja PTC za svoje programske pakete. Dostop je možen z vmesnikom, ki je bil vključen v program, sam program pa je bil napisan v jeziku C#.
Program se najprej poveže s programskim paketom Windchill Modeler, nato navigira do želenega diagrama, kar je trenutno fiksno napisano v kodi. Ko je pravi diagram najden, se preveri, ali sploh vsebuje testni primerče ga ne, se to javi uporabniku in program se zaključi
The role and importance of communication between care home staff
Full text linkUvod: Komunikacija med zaposlenimi ima ključno vlogo pri zagotavljanju kakovostne oskrbe v domovih za starostnike, saj omogoča učinkovito usklajevanje nalog, prenos informacij in vzpostavljanje zaupanja. Njena pomembnost se kaže v vplivu na odnose in zadovoljstvo zaposlenih, dobrobit stanovalcev ter na delovno okolje, kjer lahko pomanjkljiva komunikacija vodi do stresa, napak in slabše kakovosti storitev. Kljub temu se zaposleni pogosto soočajo z izzivi in ovirami, kot so pomanjkanje kadra, časovne omejitve in raznolike potrebe starejših, ki otežujejo tekoče komuniciranje.
Namen: Namen raziskave je bil preučiti vlogo in pomen komunikacije med zaposlenimi v domu za starostnike, identificirati glavne izzive ali ovire v komunikacijskem procesu ter oceniti, kako komunikacija vpliva na delo in zadovoljstvo zaposlenih ter kakovost oskrbe stanovalcev.
Metode dela: Delo temelji na kombinaciji teoretičnega pregleda literature in empirične raziskave. V teoretičnem delu so predstavljeni komunikacija, značilnosti komunikacije v organizacijah, izzivi in ovire v procesu komunikacije ter komunikacijske strategije. Empirični del je bil izveden kot kvantitativna raziskava z anketnim vprašalnikom, ki je bil razdeljen med različne profile zaposlenih v domu za starostnike – DEOS Medvode. Podatki so bili analizirani s pomočjo statističnega programa SPSS.
Rezultati: Rezultati so potrdili prvo hipotezo (H1), da komunikacijske ovire, kot so pomanjkanje časa, slaba povezanost med kadri in nejasni prenosi informacij, neposredno zmanjšujejo kakovost oskrbe. Druga hipoteza (H2), ki je predvidevala, da dobra komunikacija sama po sebi pozitivno vpliva na delovno vzdušje in zadovoljstvo, ni bila potrjena, saj se je pokazalo, da na ta vidik vplivajo tudi drugi organizacijski dejavniki. Prav tako tretja hipoteza (H3), ki je povezovala spodbujanje izražanja mnenj z večjo odprtostjo in boljšo organizacijo dela, ni bila statistično potrjena, čeprav so zaposleni to spodbudo prepoznali kot koristno. Skupni rezultati so pokazali, da je kakovost komunikacije zelo pomembna za oskrbo, a njen vpliv na delovno klimo in organizacijo dela ni enoznačen brez širše sistemske podpore.
Razprava in zaključek: Raziskava je pokazala, da je komunikacija med zaposlenimi v domu za starostnike temeljni mehanizem, ki povezuje tim in omogoča varno ter kakovostno oskrbo stanovalcev. Jasna in strukturirana izmenjava informacij prispeva k učinkovitosti in boljšemu delovnemu vzdušju, medtem ko pomanjkanje časa, nejasni prenosi ter šibka povezanost med kadri zmanjšujejo kakovost dela. Ugotovitve kažejo tudi, da sama komunikacija ni zadosten pogoj za izboljšanje zadovoljstva zaposlenih in organizacije dela, saj je njen učinek odvisen od širše podpore vodstva, kadrovskih pogojev in kulture zaupanja. Za dolgoročne izboljšave so zato nujni strukturirani pristopi, redne povratne informacije ter delovno okolje, ki spodbuja odprtost in sodelovanje zaposlenih.Introduction: Enabling efficient coordination of tasks, transmission of information, and building trust, communication among staff members plays a key role in ensuring quality care in nursing homes. Its importance is manifested in its impact on relations between staff members, their satisfaction, residents\u27 well-being, and the working environment where poor communication can lead to stress, errors, and a deterioration in the quality of services. Staff members, however, often face challenges and obstacles, such as staff shortages, time constraints, and diverse elderly needs, which make smooth communication difficult.
Aim: The research aimed to examine the role and importance of communication among staff members in a nursing home, to identify the main challenges or obstacles in the communication process, and to assess how communication affects the work and satisfaction of staff members and the quality of care for residents.
Methods: The work is based on a combination of theoretical literature review and empirical research. The theoretical part deals with communication, characteristics of communication in organizations, challenges and obstacles in the communication process, and communication strategies. The empirical part was conducted as quantitative research using a survey questionnaire, which was distributed among various profiles of staff members at a nursing home, i.e. DEOS Medvode. The data was analysed through the SPSS statistical programme.
Results: The results confirmed the first hypothesis (H1), namely that communication obstacles, such as lack of time, lack of connection between staff members, and unclear transmission of information, directly reduce the quality of care. The second hypothesis (H2), which predicted that good communication in itself had a positive impact on the working atmosphere and satisfaction, was not confirmed as other organizational factors turned out to affect this aspect as well. The third hypothesis (H3), according to which encouraging the expression of opinions was correlated with greater openness and better work organization, was not statistically confirmed eitherhowever, the staff members recognized this incentive as beneficial. The overall results showed that the quality of communication was very important in terms of the level of care but its impact on the working atmosphere was not clear-cut without broader systemic support.
Discussion and conclusion: The research showed that communication among staff members in nursing homes presents a fundamental mechanism in bringing team together and ensuring safe and high-quality care for residents. Clear and structured exchange of information contributes to efficiency and a better working environment whereas lack of time, unclear transmission, and lack of connection between staff members reduce the quality of work. The findings also show that, since its impact depends on broader management support, staffing conditions, and a culture of trust, communication alone is not a sufficient condition to increase satisfaction among staff members and to improve work organization. Structured approaches, regular feedback, and a working environment that encourages openness and participation of staff members are therefore essential for long-term improvements
CONNECTION BETWEEN TRUST IN INFLUENCERS AND CUSTUMER PURCHASE DECISIONS
Full text linkV diplomskem delu preučujemo povezavo med zaupanjem v vplivneže in nakupnimi odločitvami odjemalcev. Družbena omrežja so postala ključna platforma za oglaševanje, vplivneži pa pomembni posredniki med blagovnimi znamkami in odjemalci. Njihova moč temelji na občutku avtentičnosti in bližine, pri čemer je zaupanje odločilen dejavnik uspešnosti priporočil.
Diplomsko delo je sestavljeno iz teoretičnega in empiričnega dela. V teoretičnem delu smo opredelili odjemalce, predstavili izbrane teorije njihovega vedenja ter opisali vlogo družbenih omrežij pri oblikovanju potrošniškega vedenja. Poseben poudarek smo namenili vplivnežem in dejavnikom zaupanja, kot so iskrenost, zanesljivost, doslednost, strokovnost in transparentnost, ki bistveno vplivajo na sprejemanje njihovih priporočil.
V empiričnem delu smo s spletnim anketnim vprašalnikom analizirali vpliv zaupanja na nakupne odločitve. Rezultati kažejo, da odjemalci, ki bolj zaupajo vplivnežem, pogosteje sledijo njihovim priporočilom in opravijo nakup. Najpomembnejši dejavniki zaupanja so se izkazali zanesljivost, iskrenost in odzivnost vplivnežev. Ugotovljeno je bilo tudi, da so mlajši odjemalci dovzetnejši za vpliv vplivnežev, medtem ko starejši izražajo večjo mero previdnosti. Ugotovitve potrjujejo, da je zaupanje ključni element uspešnega vplivnostnega marketinga, saj neposredno oblikuje odnos med sledilci in blagovno znamko ter vpliva na odjemalčeve odločitve.This thesis examines the relationship between trust in influencers and consumers’ purchasing decisions. Social media has become a key platform for advertising, while influencers serve as important intermediaries between brands and consumers. Their power is based on a sense of authenticity and closeness, with trust being a decisive factor in the effectiveness of their recommendations.
The thesis consists of both theoretical and empirical parts. In the theoretical section, we defined consumers, presented selected theories of their behavior, and described the role of social media in shaping consumer behavior. Special attention was given to influencers and the trust factors—such as honesty, reliability, consistency, expertise, and transparency—that significantly affect the acceptance of their recommendations.
In the empirical part, the influence of trust on purchasing decisions was analyzed through an online survey questionnaire. The results show that consumers who trust influencers are more likely to follow their recommendations and make purchases. The most important trust factors were found to be the influencers’ reliability, honesty, and responsiveness. It was also observed that younger consumers are more susceptible to influence of influencers, while older consumers tend to exercise greater caution. The findings confirm that trust is a key element of successful influencer marketing, as it directly shapes the relationship between followers and the brand and influences consumer decisions
The role of technology in the process of asset valuation in insurance
Full text linkDiplomsko delo obravnava vpliv digitalnih tehnologij na proces cenitve premoženja v zavarovalništvu. V ospredju raziskave je razumevanje, kako sodobna orodja, kot so umetna inteligenca, strojno učenje, internet stvari, veriženje blokov in daljinsko zaznavanje, spreminjajo tradicionalne pristope k ocenjevanju škode in vrednosti premoženja. Analiza primera izbrane slovenske zavarovalnice je pokazala, da digitalizacija bistveno prispeva k večji natančnosti, učinkovitosti in preglednosti cenitev ter k zmanjšanju stroškov in časa obdelave škodnih primerov. Digitalna orodja omogočajo centralizirano obdelavo podatkov, avtomatizirano preverjanje skladnosti ter boljšo uporabniško izkušnjo zavarovancev. Hkrati digitalizacija prinaša izzive, povezane z varstvom podatkov, integracijo sistemov in etično uporabo tehnologij. Ugotovitve kažejo, da je uspešna digitalna preobrazba odvisna predvsem od pripravljenosti zaposlenih, razvoja digitalnih kompetenc in vzpostavitve zaupanja med človekom in tehnologijo. Delo se zaključi z ugotovitvijo, da digitalizacija ni le tehnična inovacija, temveč temeljna sprememba paradigme v zavarovalništvu, ki povezuje strokovno znanje, tehnologijo in človeka v sodoben, podatkovno voden sistem cenitev.The thesis explores the impact of digital technologies on the property valuation process in the insurance industry. It focuses on how modern tools such as artificial intelligence, machine learning, the Internet of Things, blockchain, and remote sensing are transforming traditional approaches to asset and damage assessment. The analysis of a selected Slovenian insurance company shows that digitalization significantly improves the accuracy, efficiency, and transparency of valuation procedures, while reducing costs and processing time. Digital tools enable centralized data management, automated compliance control, and an enhanced customer experience. At the same time, digitalization introduces challenges related to data protection, system integration, and the ethical use of technology. The findings indicate that the success of digital transformation largely depends on employee readiness, the development of digital competencies, and building trust between humans and technology. The study concludes that digitalization is not merely a technological upgrade but a fundamental paradigm shift in insurance, connecting expertise, technology, and people into a modern, data-driven valuation system

Conversion of waste from the vegetable oil industry into efficient adsorbents for dye removal
Full text linkThe discharge of synthetic dyes into aquatic environments poses a significant environmental threat. Waste from the vegetable oil industry, such as hemp oil cake, offers a low-cost feedstock for the production of carbonaceous adsorbents for water purification due to its high carbon content and availability. In this study, hydrochars produced from hemp oil cake and cheese whey were thermo-chemically modified using natural vinegars and compared with conventional modifiers, then tested for adsorption of bromocresol green (BCG) and methylene blue (MB) dyes. According to FTIR, BET and SEM-EDS analyses, modifications with alcoholic and wine vinegar, acetic acid and KOH significantly altered the structural properties of the hydrochars, increasing the specific surface area from 1.60 to 234.35, 260.73, 71.32 and 582.84 m²/g, respectively. Among the acid-modified hydrochars, the hydrochar modified with alcoholic vinegar was the most effective, with an adsorption capacity of 15.45 mg/g for BCG and 62.16 mg/g for MB, as determined by Langmuir kinetic model, while the unmodified hydrochar had lower capacities. In comparison, the highest adsorption capacities for KOH-modified hydrochar were 640.15 mg/g for MB and 38.17 mg/g for BCG. Adsorption kinetics mostly followed a pseudo-second order model, indicating a combination of chemical and physical adsorption mechanisms driven byelectrostatic interactions, hydrogen bonding and π–π interactions. Isothermal kinetic modelling revealed heterogeneous adsorption behaviour, with the Redlich-Peterson and Freundlich models providing the best fit to the experimental data. The results emphasise the enhanced effectiveness of thermo-chemically modified hemp oil cake hydrochars for sustainable dye removal and water purification applications

V nalogi smo predstavili primere iz tujine, kjer smo opisal, kako se vinarji povezujejo drugod po svetu, ter podal njihova mnenja o povezovanju. Temo smo nato postavili v lokalno okolje ter predstavil primere povezovanja pri nas. Štajerska regija v Sloveniji je ena izmed glavnih vinskih regij z bogato vinsko tradicijo in kulturo. Skozi primer »Najstarejše trte«, ki deluje v okviru Zavoda za turizem Maribor, sem predstavil njihovo premišljeno delo, kjer skrbijo za preplet tradicije in dediščine ruralnega okolja z urbanim okoljem. »Najstarejša trta«, zgodovinska ustanova in trenutno vinoteka, kjer ponujajo vina 60 vinarjev iz regije, ter z njo povezani dogodki, je predstavljena kot primer dobre prakse lokalnega povezovanja. Takšen način delovanja omogoča konstanten razvoj trajnostnega kmetijstva, razvoj ruralnega okolja na Štajerskem ter ekonomsko blaginjo vinarjev v regiji. Učinkovitost dela »Najstarejše trte« smo preverili tudi z anketno raziskavo med obiskovalci. Anketirance smo povprašali o njihovem splošnem mnenju glede lokalnega povezovanja, kako dojemajo lokalno povezovanje in kako to začutijo skozi zgodbo »Najstarejše trte«. Rezultate smo obdelali s pomočjo Microsoft Excela. Rezultati ankete so potrdili, da je delo »Najstarejše trte« dobro premišljeno in učinkovito na področju lokalnega povezovanja.In my thesis, we focused on the topic of local networking in agriculture, on what local networking means, the possible ways of networking, and more specifically, how networking operates in the world of winemaking. We presented examples from abroad, describing how winemakers connect in different parts of the world and their opinions on networking. We then applied the topic to the local environment and presented examples of networking in Slovenia. The Styria region is one of the main wine regions in Slovenia, with a rich wine tradition and culture. Through the example of the “Oldest Vine,” which operates within the Maribor Tourism Institute, I presented their deliberate work, where they carefully intertwine tradition and the heritage of rural areas with the urban environment. The “Oldest Vine,” a historical institution and currently a wine shop offering wines from 60 winemakers in the region, along with its associated events, is presented as an example of good local networking practice. This approach ensures the continuous development of sustainable agriculture, the development of rural areas in Styria, and the economic prosperity of winemakers in the region. The effectiveness of the “Oldest Vine” was also confirmed through a survey conducted among its visitors. Respondents were asked about their general opinion on local networking, how they perceive it, and how they experience it through the story of the “Oldest Vine.” The results were processed using Microsoft Excel. The survey results confirmed that the work of the “Oldest Vine” is well-thought-out and effective in the field of local networking
Nutrition of patients with kidney transplants

Uvod: Kronična ledvična bolezen je postopno napredujoče stanje, ki lahko vodi v končno ledvično odpoved. Presaditev ledvice predstavlja enega izmed najpomembnejših načinov zdravljenja končne ledvične odpovedi. Po presaditvi ima prehrana ključno vlogo pri dolgoročnem delovanju presadka ter pomembno prispeva k izboljšanju kakovosti življenja.
Metode: Zaključno delo temelji na pregledu znanstvene literature o vplivu prehrane na ohranjanje ledvične funkcije po presaditvi ledvice. Uporabljena je bila metoda PIO za strukturirano iskanje virov, izbor literature pa je potekal v skladu s smernicami PRISMA. Vključene raziskave so bile ovrednotene na podlagi hierarhije dokazov. Rezultati so predstavljeni v evalvacijski tabeli ter sintetizirani z uporabo narativne sinteze.
Rezultati: Ugotovili smo, da ustrezna prehrana pomembno vpliva na dolgoročno ohranjanje funkcije ledvičnega presadka, zmanjšuje tveganje za zaplete in izboljšuje kakovost življenja pacientov po transplantaciji. Bistveni prehranski poudarki so uravnotežen vnos beljakovin, nadzor elektrolitov ter individualno prilagojena prehranska obravnava glede na fazo zdravljenja. Posebno učinkoviti so celostni prehranski vzorci, kot so mediteranska, rastlinsko usmerjena in DASH (Dietary Approaches to Stop Hypertension) dieta.
Razprava in zaključek: Rezultati kažejo, da je prehranska obravnava bistvena komponenta uspešnega dolgoročnega zdravljenja po presaditvi ledvice. Treba je okrepiti ozaveščanje in podporo pacientom pri upoštevanju individualnih prehranskih smernic, kar bi lahko dolgoročno prispevalo k boljši funkciji presadka, manjši pojavnosti zapletov ter izboljšani kakovosti življenja.Abstract
Introduction: Chronic kidney disease is a progressively advancing condition that can lead to end-stage renal failure. Kidney transplantation represents one of the most important methods of treating end-stage renal disease. After transplantation, nutrition plays a crucial role in the long-term functioning of the graft and significantly contributes to improving quality of life.
Methods: This thesis is based on a review of scientific literature on the impact of nutrition on maintaining kidney function after transplantation. The PIO method was used for structured source searching, and the selection of literature followed PRISMA guidelines. The included studies were assessed based on the hierarchy of evidence. The results were presented in a evaluation table and synthesized using a narrative synthesis.
Results: We found that appropriate nutrition significantly affects the long-term maintenance of kidney graft function, reduces the risk of complications, and improves the quality of life of patients after transplantation. Key dietary focuses include a balanced intake of proteins, electrolyte control, and individually tailored dietary management according to the stage of treatment. Comprehensive dietary patterns, such as the Mediterranean diet, plant-based diets, and the DASH (Dietary Approaches to Stop Hypertension) diet are particularly effective.
Discussion and conclusion: The results show that dietary management is an essential component of successful long-term treatment after kidney transplantation. It is necessary to strengthen awareness and provide support to patients in following individual dietary guidelines, as this can significantly contribute to better graft function, fewer complications, and improved quality of life
