Energetsko načrtovanje hladilnice jabolk : magistrsko delo
Žan Bregar, 2024, master's thesis

Abstract: V okviru magistrske naloge smo se posvetili projektiranju hladilnice za skladiščenje jabolk, kjer smo podrobno raziskali ključne vidike načrtovanja in izvedbe kompleksnih sistemov za ohranjanje kakovosti sadja. Naša analiza je zajemala pregled uporabljene opreme za hlajenje, izračune potrebne hladilne moči, določitev optimalne debeline izolacije ter temeljito preučevanje osvetlitve celotne hladilnice. Pravilno načrtovanje hladilnic ima ključno vlogo pri ustvarjanju optimalnih pogojev za shranjevanje jabolk, kar omogoča dolgoročno ohranjanje svežine in kakovosti sadja. Izračuni potrebnih hladilnih moči in debeline izolacije nudijo trdne osnove za tehnično izvedbo hladilnice, ki učinkovito vzdržuje predpisane temperature in vlago.
Keywords: hladilnice, hladilna moč, izolacija, strojna oprema, skladiščenje

Using structural equation modeling to explore patients’ and healthcare professionals’ expectations and attitudes towards socially assistive humanoid robots in nursing and care routine
Izidor Mlakar, Urška Smrke, Vojko Flis, Nina Kobilica, Samo Horvat, Bojan Ilijevec, Bojan Musil, Nejc Plohl, 2023, original scientific article

Abstract: Healthcare systems around the world are currently witnessing various challenges, including population aging and workforce shortages. As a result, the existing, overworked staff are struggling to meet the ever-increasing demands and provide the desired quality of care. One of the promising technological solutions that could complement the human workforce and alleviate some of their workload, are socially assistive humanoid robots. However, despite their potential, the implementation of socially assistive humanoid robots is often challenging due to low acceptance among key stakeholders, namely, patients and healthcare professionals. Hence, the present study first investigated the extent to which these stakeholders accept the use of socially assistive humanoid robots in nursing and care routine, and second, explored the characteristics that contribute to higher/lower acceptance within these groups, with a particular emphasis on demographic variables, technology expectations, ethical acceptability, and negative attitudes. In study 1, conducted on a sample of 490 healthcare professionals, the results of structural equation modeling showed that acceptance is driven primarily by aspects of ethical acceptability, although education and technology expectations also exert an indirect effect. In study 2, conducted on a sample of 371 patients, expectations regarding capabilities and attitudes towards the social influence of robots emerged as important predictors of acceptance. Moreover, although acceptance rates differed between tasks, both studies show a relatively high acceptance of socially assistive humanoid robots. Despite certain limitations, the study findings provide essential knowledge that enhances our understanding of stakeholders’ perceptions and acceptance of socially assistive humanoid robots in hospital environments, and may guide their deployment.

Nabavni proces v podjetju Pošta Slovenije d. o. o.
Urška Jerebic, 2024, undergraduate thesis

Abstract: Nabava je proces, ki odločilno vpliva na razvoj podjetja. Zelo pomemben je kakovosten odnos med podjetjem in dobavitelji, predvsem takrat, ko poslovna partnerja skupaj rasteta ter se razvijata. V podjetju sami brez podpore ne bi morali spremljati razvoja na vseh področjih. Ravno ob tem se pokaže odnos z dobavitelji, ki s svojim znanjem izobražujejo zaposlene v podjetju o novostih na trgu. Nabava torej skrbi, da izdelki sledijo trendom in izpolnjevanju potreb kupcev. Diplomsko delo je sestavljeno iz dveh delov. V teoretičnem delu smo podrobno predstavili vlogo in cilje nabave v podjetju ter podrobno opisali korake nabavnega procesa. Prav tako smo predstavili, kako pomembno je, da nabavni oddelek sodeluje z ostalimi oddelki v podjetju. Opisali smo orodje TCO (Total Cost of Ownership of Component) in pojasnili, kako je pandemija COVID-19 vplivala na podjetja ter nabavo v Sloveniji. V praktičnem delu smo predstavili podjetje Pošta Slovenije d. o. o., njene cilje, vizije in poslanstvo. V nadaljevanju je na podlagi podjetja Pošta Slovenije podrobno predstavljen nabavni proces, statistika izvedenih postopkov javnega naročanja omenjenega podjetja v letu 2023. Prav tako smo pisali tudi o tem, kako je rusko-ukrajinska vojna vplivala na poslovanje podjetja.

Measuring young individuals’ responses to climate change : validation of the Slovenian versions of the climate anxiety scale and the climate change worry
Nejc Plohl, Izidor Mlakar, Bojan Musil, Urška Smrke, 2023, original scientific article

Abstract: Introduction: While increasing awareness of climate change is needed to address this threat to the natural environment and humanity, it may simultaneously negatively impact mental health. Previous studies suggest that climate-specific mental health phenomena, such as climate anxiety and worry, tend to be especially pronounced in youth. To properly understand and address these issues, we need valid measures that can also be used in non-Anglophone samples. Therefore, in the present paper, we aimed to validate Slovenian versions of the Climate Anxiety Scale (CAS) and the Climate Change Worry Scale (CCWS) among Slovenian youth. Method: We conducted an online survey in which 442 young individuals (18–24 years) from Slovenia filled out the two central questionnaires and additional instruments capturing other relevant constructs (e.g., general anxiety, neuroticism, and behavioral engagement). Results: The confirmatory factor analyses results supported the hypothesized factorial structure of the CAS (two factors) and the CCWS (one factor). Both scales also demonstrated great internal reliability. Moreover, the analyses exploring both constructs’ nomological networks showed moderate positive associations with similar measures, such as anxiety and stress (convergent validity), and very weak associations with measures they should not be particularly related to, such as narcissism (discriminant validity). Lastly, we found that the CAS and, even more so, the CCWS have unique predictive value in explaining outcomes such as perceived threat, support for climate policies, and behavioral engagement (incremental validity). Discussion: Overall, Slovenian versions of the CAS and the CCWS seem to be valid, reliable, and appropriate for future studies tackling young individuals’ responses to climate change. Limitations of the study and areas for future research are discussed.

Uporaba ultrazvoka pri vstavitvi žilnih katetrov pri pacientu v urgentni ambulanti
Urška Završnik, 2024, master's thesis

Abstract: Uvod: Za lažjo vstavitev žilnih katetrov je priporočljiva uporaba ultrazvoka. Ultrazvok je namreč hitra in zanesljiva metoda pri oteženem venskem dostopu, s katero lahko prihranimo čas in se tako izognemo kasnejšim nepotrebnim vstavitvam centralnega venskega katetra in njihovim zapletom. Namen zaključnega dela je bil raziskati prednosti uporabe ultrazvoka pri vstavitvi žilnih katetrov pri bolniku v urgentni ambulanti v primerjavi s klasično slepo vstavitvijo žilnih katetrov. Metode: Uporabili smo metodo pregleda, analize in sinteze znanstvene literature ter metodo kompilacije in komparacije. Za izvedbo pregleda literature smo upoštevali PRISMA-smernice, članke pa smo ocenili s pomočjo Joana Briggs Institutes ocenjevalnega orodja. Za prikaz analize podatkov je bila uporabljena vsebinska analiza. Rezultati: V raziskavi smo prepoznali 177 člankov, od katerih smo v končno analizo vključili 12 člankov. Ugotovili smo, da je ultrazvočno vodena tehnika uspešnejša ter hitrejša od tradicionalne/slepe tehnike vstavitve žilnega katetra. S pomočjo ultrazvoka se zmanjšata čas vstavitve in število, pojavi pa se manj zapletov, zabeležena je nižja stopnja bolečine ter večje zadovoljstvo bolnikov. Razprava in zaključek: Žilni katetri so nujno potrebni za obravnavo kritično bolnih bolnikov in za aplikacijo intravenske terapije. Za lažjo in hitrejšo nastavitev intravenskega dostopa si lahko pomagamo z ultrazvokom, ki ima trenutno svoje mesto predvsem pri urgentnih stanjih, neizkoriščena pa je uporaba ultrazvoka v vsakdanji rabi.

Energetska in masna bilanca hlajenja dimnih plinov v hladilni komori po izstopu iz steklarske peči ogrevane z zemeljskim plinom in kisikom
Urška Zupanc, 2024, undergraduate thesis

Abstract: Steklo predstavlja trajnostni produkt, saj je njegova popolna možnost recikliranja ključen dejavnik v zmanjševanju okoljskega vpliva. Možnost ponovne uporabe stekla ne le zmanjšuje količino odpadkov, ampak tudi ohranja naravne vire, saj recikliranje zmanjšuje potrebo po novih surovinah. Med procesom pridobivanja-taljenja stekla nastane kar nekaj stranskih produktov v obliki dimnih plinov. Ti nastanejo pri zgorevanju zemeljskega plina s kisikom in pri razpadu surovin za vnos alkalijskih in zemljo alkalijskih oksidov v obliki karbonatov, ki imajo zelo visoko temperaturo (okoli 1400 °C). Te pline je potrebno pred vstopom v toplotne izmenjevalce voda-zrak ohladiti na 400 do 500 °C. Dimne pline lahko ohlajamo na dva načina: z vpihovanjem hladilnega zraka in (ali) z vpihovanjem vodne megle v tok dimnih plinov. Med izvajanjem diplomske naloge smo ugotavljali razliko med porabo energije v primeru, ko pline ohlajamo samo z zrakom ali z vodno meglo. Prav tako smo primerjali izmerjene količine s teoretično izračunanimi. Pri teoretičnem izračunu smo upoštevali povprečne vrednosti fizikalnih lastnosti plinov v dimnih plinih za dane temperaturne intervale. Izračunali smo masno bilanco peči in hladilne komore, ter potrdili oz. ovrgli zakon o ohranitvi mase. Diplomska naloga je nastala v sodelovanju s Steklarno Hrastnik, d. o. o.. Vse meritve so potekale na G – peči, ki se nahaja v poslovni enoti Vitrum.
Keywords: steklo, steklarska peč, zgorevanje zemeljskega plina, dimni plini, hlajenje dimnih plinov, energetska bilanca, masna bilanca.

Fatal Hymenoptera Venom–triggered anaphylaxis in patients with unrecognized clonal mast cell disorder : Is mastocytosis to blame?
Matija Rijavec, Jezerka Inkret, Urška Bidovec, Tanja Carli, Nina Frelih, Andreja Kukec, Peter Korošec, Mitja Košnik, 2023, original scientific article

Abstract: Hymenoptera venom–triggered anaphylaxis (HVA) affects up to 8.9% of the general population and is the most frequent cause of anaphylaxis in adults, accounting for approximately 20% of all fatal anaphylaxis cases. Quite often, a fatal reaction is a victim’s first manifestation of HVA. Mastocytosis represents one of the most important risk factors for severe HVA. We analyzed patients with documented fatal HVA for the presence of underlying clonal mast cell disorder (cMCD). Here, we report three cases of fatal HVA, with undiagnosed underlying cMCD identified by the presence of the peripheral blood and/or bone marrow KIT p.D816V missense variant postmortem. In the first case, anaphylaxis was the initial episode and was fatal. In the other two cases, both patients were treated with specific venom immunotherapy (VIT), nevertheless, one died of HVA after VIT discontinuation, and the other during VIT; both patients had cardiovascular comorbidities and were taking beta-blockers and/or ACE inhibitors. Our results point to the importance of screening all high-risk individuals for underlying cMCD using highly sensitive molecular methods for peripheral blood KIT p.D816V variant detection, including severe HVA and possibly beekeepers, for proper management and the need for lifelong VIT to prevent unnecessary deaths. Patients at the highest risk of fatal HVA, with concomitant cardiovascular and cMCD comorbidities, might not be protected from field stings even during regular VIT. Therefore, two adrenaline autoinjectors and lifelong VIT, and possibly cotreatment with omalizumab, should be considered for high-risk patients to prevent fatal HVA episodes.

Prenovitev kriterijev za vertikalno in horizontalno napredovanje v podjetju palfinger d.o.o.
Urška Regvat, 2024, master's thesis

Abstract: V delu preučujemo prenovitev sistema napredovanja v organizciji. Potreba po prenovi sistema prihaja iz staromodnega in pomanjkljivega sistema, novi sistem napredovanja pa vključuje vse zaposlene, ne da bi se pozabilo na določene zaposlene, ki nase ne opozarjajo. S pomočjo mamdani fuzzy modela uvajamo kriterije, kjer se izpostavi tiste, ki so najbolj primerni za napredovanje ali povišanje ranga. Kriterij se deli osnovno na dva dela, in sicer na osebnostni in neosebnostni kriterij, vsak od njiju pa ima opredeljene podkriterije. Kadar govorimo o načinu napredovanja, vertikalnem ali horizontalnem, s tem povezujemo tudi količino odgovornosti, ki jo zaposleni pridobi. V obeh načinih se odgovornost poveča, lahko je to drugo odgovornejše delo, odgovornost do nadrejenega ali dodatno dodeljeno delo, ki mora biti opravljeno. Mamdani fuzzy model je primeren za osnovno postavitev kriterijev napredovanja, saj z njegovo pomočjo postavimo logiko povezovanja, ki nam pomaga pri postavitvi na primer excel tebele s formulami, ki opredelijo in določijo najprimernejše za napredovanje. Ob postaviti tabele in sklepnem povezovanju smo ugotovili, da izobrazba ni med najpomembnejšimi kriteriji pri napredovanju. Večkrat je pomembna pri zaposlitvi, vendar ne tudi pri napredovanju, saj se za zaposlene točno ve, kakšne so njegove sposobnosti in karakteristike.
Keywords: Napredovanje, horizontalno napredovanje, vertikalno napredovanje, prenova sistema napredovanja, kriteriji za napredovanje.
