1. Developing a diversification strategy of non-agricultural activities on farms using system dynamics modelling : a case study of SloveniaMaja Borlinič Gačnik, Boris Prevolšek, Karmen Pažek, Črtomir Rozman, Andrej Škraba, 2022, izvirni znanstveni članek Opis: Purpose: This paper aims to analyse the main variables and causal relationships in the system structure of the diversification of non-agricultural activities on agricultural holdings using system dynamics (SD) modelling. The SD model aims to simulate depictions of the behaviour of the real system while testing the effects of alternative decisions over time.
Design/methodology/approach: An SD methodology was chosen to model diversification in farm tourism.
Findings: A system approach increases the authors’ understanding of the transition of agricultural holdings to farm tourism. The results indicate that the transition to farm tourism depends on the level of tourism development in a certain area. The system is influenced by subsidies allocated by authorities to expand primary agricultural activities. The model describes a situation in which the tourism and agricultural industries have been affected by the COVID-19 pandemic.
Research limitations/implications: The research is limited by the small set of available data due to the limited number of farms in Slovenia. One major problem is the difference in statistical data on the same activity collected from different institutions in Slovenia.
Practical implications: The paper includes implications for understanding the transition process to farm tourism, allowing policymakers to experiment with subsidies and promotion to explore the efficacy and efficiency of proposed policies.
Originality/value: This study provides a structured, systemic view of the diversification of non-agricultural activities on agricultural holdings, where the simulation results are a reliable reflection of the behaviour of the actual system being modelled.

3. Information technology for business sustainability : a literature review with automated content analysisDoroteja Vidmar, Marjeta Marolt, Andreja Pucihar, 2021, pregledni znanstveni članek Opis: An extremely dynamic and fast-moving environment is pushing enterprises to continuous innovation and change. Managing sustainability in a digitalized environment seems to be of central importance for policy makers, as information technologies (IT), in combination with sustainability objectives, offer a wide range of opportunities for positive change. Through a systematic literature review and the application of automated content analysis, this study aims to provide insights into the latest research in the interdisciplinary field of sustainable business models and information systems. The results of the analysis, combined with a researcher’s perspective, suggest that IT, which can be used to achieve sustainability objectives, are already in place and have an infinite number of potential implications in the future. The results suggest that positive economic, social, and environmental changes can be achieved by using IT as long as they are used to identify unsustainable actions and enable positive change. The analysis of research trends revealed a discrepancy between the research in the European Union and the rest of the world and pointed to several avenues for future research.

4. Comparative analysis of human and artificial intelligence planning in production processesMatjaž Roblek, Tomaž Kern, Eva Krhač Andrašec, Alenka Brezavšček, 2024, izvirni znanstveni članek Opis: Artificial intelligence (AI) has found applications in enterprises′ production planning
processes. However, a critical question remains: could AI replace human planners? We conducted a
comparative analysis to evaluate the main task of planners in an intermittent process: planning the
duration of production orders. Specifically, we analysed the results of a human planner using master
data and those of an AI algorithm compared to the actual realisation. The case study was conducted
in a large production company using a sample of production products and machines. We were able
to confirm two of the three research questions (RQ1 and RQ3), while the results of the third question
(RQ2) did not meet our expectations. The AI algorithms demonstrated significant improvement with
each iteration. Despite this progress, it is still difficult to determine the exact threshold at which AI
outperforms human planners due to the unpredictability of unexpected events. Even though AI
significantly improves prediction accuracy, the inherent variability and incomplete input data pose a
major challenge. As progress is made, robust data collection and management strategies need to be
integrated to bridge the gap between the potential of AI and its practical application, fostering the
symbiosis between human expertise and AI capabilities in production planning.

5. Effects of cardiac rehabilitation and diet counselling on adherence to the mediterranean lifestyle in patients after myocardial infarctionMarko Novaković, Uroš Rajkovič, Daniel Košuta, Jure Tršan, Zlatko Fras, Borut Jug, 2022, izvirni znanstveni članek Opis: Adherence to the Mediterranean lifestyle—as captured by the Medlife Index Questionnaire (i.e., encompassing a Mediterranean diet as well as other aspects of healthy living, such as food preparation, physical activity, and socializing)—has been associated with reduced cardiovascular events in healthy individuals. In the present study, we sought to determine the adherence to, and the effect of comprehensive cardiac rehabilitation on, Mediterranean lifestyle adherence in patients after myocardial infarction. We included 121 patients (mean age, 55 years; women, 37%) undergoing comprehensive cardiac rehabilitation—i.e., exercise training 3 times per week for 12 weeks plus dedicated workshops promoting the Mediterranean lifestyle. Before and after cardiac rehabilitation, patients completed the Medlife Index Questionnaire. High baseline adherence was associated with favourable glucose (5.39 vs. 6.1 mmol/L; p < 0.001), triglycerides (1.1 vs. 1.5 mmol/L; p = 0.002), and HDL cholesterol levels (1.32 vs. 1.12 mmol/L; p = 0.032). More importantly, the Medlife Score significantly improved following comprehensive cardiac rehabilitation in patients with low baseline adherence (from 13.8 to 16.7 points; p < 0.001), but not in patients with high baseline adherence (from 19.4 to 18.8 points; p = 0.205). Our findings suggested that Mediterranean lifestyle promotion during cardiac rehabilitation improved adherence to the Mediterranean lifestyle, especially in low-adherence patients.

6. Primus inter pares effect in high schoolsDenis Dizdarević, Robert Leskovar, Goran Vukovič, 2024, izvirni znanstveni članek Opis: Primus inter pares effect or better-than-average effect is cognitive bias known as illusory superiority in which individuals overestimate their positive abilities and traits in comparison to others. Overestimation and bias are often accompanied with various dangers on a personal, organizational or even societal level. We investigated the presence of overestimation among high school graduates in Slovenia in areas of teamwork, interpersonal skills, emotional intelligence, problem solving, and decision making. Although overestimation was present in all areas, results have also shown indications of indecisiveness. Overestimation was highest in the area of interpersonal skills, which is more of a social skill area in comparison with decision making or problem solving. Individuals probably receive more feedback over the course of high school in decision making, problem solving, and teamwork than in interpersonal skills, as those can directly impact grades while interpersonal skills less so.

7. Nadgradnja ogrevalnega sistema z internetom stvariBranko Zebec, 2024, magistrsko delo Opis: Magistrsko delo vsebuje analizo in razvoj prototipa za nadgradnjo ogrevalnega sistema, pri katerem smo sledili dvema ciljema: povezati ogrevalni sistem v internetno omrežje s pomočjo tehnologije interneta stvari in optimizirati ogrevalni sistema. Za dosego ciljev smo raziskali vse potrebne tehnologije, programska orodja in strojno opremo. Pri implementaciji smo uporabili programsko platformo Home Assistant, s katero smo razvili glavni krmilnik na strojni opremi Raspberry Pi 4. V okviru platforme Home Assistant smo integrirali dodatna programska orodja: Cloudflare za vzpostavitev varne povezave na oblačni strežnik in s tem ustvarjanje varnega tunela do glavnega krmilnika, Node-RED, s katerim smo razvili programsko kodo za povezavo z napravami Modbus in optimizacijo sistema vključno s PID krmilnikom, InfluxDB za bazo podatkov vseh spremenljivk našega ogrevalnega sistema, Grafano za vizualizacijo podatkov iz baze, Google SDK za integracijo Googlovega pomočnika na Home Assistant. Na krmilnik smo povezali naprave prek protokola Modbus TCP/IP (angl. Transmission Control Protocol/Internet Protocol): Daikin krmilnik za dostop do toplotne črpalke Daikin Altherma HT, Siemens sobni termostat. Za spremljanje porabe električne energije smo razvili merilnik porabe na modulu ESP32, ki smo ga povezali na kontakte S0 analognega števca. Programsko kodo C++ smo povzeli in prilagodili ter povezali prek protokola MQTT na Home Assistant. Razvili smo tudi simulacijski model, s pomočjo katerega smo preverjali nastavitve PID krmilnika. S statistično analizo smo preverili, ali so podatki po optimizaciji sistema resnično potrdili pričakovane rezultate glede zmanjšanja porabe električne energije, manjšega vtoka ogrevalne vode ter sprememb sobne temperature. Prototip smo preverjali v celotnem ogrevalnem obdobju, le-ta je deloval zanesljivo brez izpadov. Za oddaljeni dostop smo uporabljali Home Assistant pomočnika in Googlovega pomočnika. Optimizacija ogrevalnega sistema se je izkazala za zelo uspešno, kar smo potrdili z meritvami spremenljivk, predvsem porabe električne energije. Ugotovili smo, da se v prehodnem obdobju ogrevanja poraba znatno zmanjša. Na podlagi tega smo prepričani, da bomo na dolgi rok podaljšali življenjsko dobo toplotne črpalke ter prispevali k trajnostni naravnanosti našega sistema ogrevanja.

8. Enakost spolov na trgu dela v SlovenijiNeža Žugelj Gašperšič, 2024, magistrsko delo Opis: Vsak dan se srečujemo s problematiko enakosti spolov na trgu dela. Gre za kompleksen problem, ki je sestavljen iz veliko različnih dejavnikov. V magistrsem delu smo proučevali mnenja žensk in moških o enakosti spolov na trgu dela v Sloveniji in ugotavljali, ali je med mnenji glede na spol možno opaziti določene razlike. Natančneje smo i raziskali, kakšen pogled imajo ženske in moški na plačne vrzeli med spoloma. Zanimalo nas je, kakšna so mnenja anketirancev o tradicionalnih vlogah glede na različne starostne skupine in glede na spol. Izhajali smo iz dejstva, da tradicionalne vloge spolov močno vplivajo na segregacijo poklicev po spolu. Proučevali smo, kako se razlikujejo mnenja o prisotnosti spolne diskriminacije na delovnem mestu glede na spol in končano izobrazbo anketirancev. Zanimalo nas je tudi, kakšen pogled imajo anketiranci na vlogo javne politike in vlade pri odpravljanju neenakosti med spoloma na delovnem mestu. Raziskava je izvedena z anketnim vprašalnikom, ki smo ga poslali zaposlenim v različnih panogah in sektorjih. Rezultati kažejo, da je možno opaziti razlike v mnenjih o enakosti spolov na trgu dela v Sloveniji glede na spol, starost in končano izobrazbo anketirancev. Ženske v povprečju menijo, da je neenakost spolov na trgu dela problem, moški pa v povprečju do problema niso opredeljeni. Glede na izobrazbo in starost se razlike v mnenjih kažejo pri moških starih med 33 in 49 let, ki ne odstopajo od tradicionalnih vlog spolov ter moških s končano več kot srednjo šolo, ki imajo nevtralen pogled na spolno diskriminacijo na delovnem mestu. Kljub temu je mnenje žensk in moških o določenih problematikah neenakosti spolov na trgu dela dokaj enotno, kar kaže na napredek in manjšanje vrzeli med spoloma. Še vedno je možno opaziti močan vpliv tradicionalnih vlog spolov, diskriminacije in pristranskosti ter močno segregacijo poklicev glede na spol.

9. Stres med medicinskimi sestrami v urgentnem centruArijana Smajlović, 2024, magistrsko delo Opis: Delo v zdravstveni negi je odgovorno in zahtevno, kajti skrb za pacienta in njegove potrebe predstavlja prioriteto vsaki medicinski sestri. Pogosto pa se poleg izvajanja aktivnosti zdravstvene nege srečujejo z mnogimi drugimi stresnimi situacijami. Nepredvidljive situacije pa so posebej značilne za medicinske sestre na urgenci.
Magistrsko delo je sestavljeno iz teoretičnega in empiričnega dela. Za izdelavo teoretičnega dela smo pregledali slovensko in tujo literaturo. Zanimalo nas je, kateri so glavni stresorji pri delu zaposlenih in vzroki za izgorelost zaposlenih, kakšne so posledice izgorelosti za zaposlene in organizacije ter katere so najbolj učinkovite strategije za obvladovanje stresa pri zaposlenih. V empiričnem delu smo skladno z namenom, cilji in hipotezami izvedli raziskavo, ki temelji na deskriptivni kvantitativni metodi – opravili smo presečno raziskavo. Podatke smo zbrali s pomočjo anketnega vprašalnika med zaposlenimi v dveh urgentnih centrih. Anketiranje je potekalo od sredine maja do začetka avgusta 2024. Pridobljene podatke smo računalniško obdelali s pomočjo računalniškega programa Microsoft Exel 2016, nato pa smo jih analizirali s pomočjo deskriptivne in inferenčne statistike. Zastavljene hipoteze smo preverili s pomočjo statističnega programa IBM SPSS različica 29.0 za operacijski sistem Microsoft Windows (IBM Corp. Armonk, NY, ZDA).
En (2,1 %) anketirani je ocenil svojo raven stresa pri vsakodnevnem delu kot visoko, kar je bilo statistično značilno pod pričakovanji v višini 70 % (binomski test = 32,0294; p < 0,001). Ženske so se statistično značilno pogosteje v preteklem mesecu počutile nervozne in pod stresom kot moški (U = 140,000; p = 0,049). Prav tako so se ženske statistično značilno pogosteje počutile, kot da nakopičenih težav ne morejo premagati kot moški (U = 141,000; p = 0,050). Višja delovna doba je bila povezana z boljšim obvladovanjem sprememb in dogodkov v življenju (r = 0,334; p = 0,020). Ugotovili smo, da je izmensko delo 11 (22,9 %) anketiranih navedlo kot dejavnik stresa, kar je bilo statistično značilno pod pričakovanji v višini 70 % (binomski test = 15,558; p < 0,001). Izgorelost anketiranih je bila statistično značilno pod pričakovanji (> 75 točk po CBI) pri vseh treh dimenzijah (p < 0,001). Stopnja izgorelosti se med anketiranimi ni statistično značilno razlikovala glede na spol, stopnjo izobrazbe, delovno dobo ali starost anketiranih (p > 0,05).

10. Avtomatizacija zbiranja podatkov iz senzorjev na izvodih transformatorjaMatic Mikec, 2024, diplomsko delo Opis: Informacije, ki jih pridobimo iz podatkov, igrajo pomembno vlogo pri odločanju in spodbujanju inovativnosti v osebnem in tudi poslovnem življenju. V diplomskem delu smo razvili avtomatizirani sistem za prenos podatkov iz naprav interneta stvari (senzorji) na transformatorskih izvodih do strežnika, kjer se ti podatki hranijo. Za načrtovanje različnih korakov pridobivanja, obdelovanja in shranjevanja podatkov smo uporabili različne programske rešitve, kot so Eclipse Mosquitto, Python in PostgreSQL z razširitvijo TimescaleDB, ki smo jih tudi opisali v svojem delu. Izdelan prototip je zasnovan za naročnika Elektro Gorenjska, d. d., in zagotavlja podatke za nadaljnjo analizo v okviru agencijskega projekta.
