Analysis of some properties of refuse derived fuel from waste for energy recovery
Get PDFKljub prizadevanjem za zmanjševanje količin odpadkov kot družba še vedno proizvedemo ogromne količine le-teh. Eden ključnih izzivov sodobnega ravnanja z odpadki je preprečevanje njihovega odlaganja, pri čemer ima pomembno vlogo energetska izraba odpadkov.
V diplomski nalogi smo se osredotočili na nastanek, ločevanje in energetsko izrabo trdnega goriva iz odpadkov (TGO) v okviru Javnega podjetja Snaga. Posebno pozornost smo namenili analizi vpliva sestave, vsebnosti vlage in deleža inertnih snovi na kurilno vrednost TGO. Pridobljene rezultate smo primerjali s teoretičnimi izračuni.
Ugotovili smo, da embalažna frakcija dosega najvišje kurilne vrednosti, medtem ko ima težka fina frakcija najnižje. Rezultati potrjujejo, da ima TGO – ob ustrezni obdelavi in pripravi – visok energetski potencial, s čimer lahko dopolnjuje tradicionalne vire energije in pomembno prispeva k trajnostnemu ravnanju z odpadki.Despite ongoing efforts to reduce waste generation, society continues to produce large amounts of waste. One of the key challenges in modern waste management is the prevention of landfilling, where energy recovery from waste plays a crucial role.
This thesis focuses on the generation, separation, and energy recovery of Solid Recovered Fuel (SRF) at the Javno podjetje Snaga. Special attention was given to analyzing the influence of composition, moisture content, and the proportion of inert materials on the calorific value of SRF. The measured values were compared with theoretical calculations.
Our findings show that the packaging fraction achieves the highest calorific values, while the fine heavy fraction shows the lowest. The results confirm that, when properly processed, SRF has significant energy potential and can effectively supplement traditional energy sources, contributing to more sustainable waste management practices
Manipulation of financial instruments market using online platforms
Get PDFPrispevek analizira učinkovitosti veljavne zakonodaje na področju naraščajoče grožnje tehnološkega manipuliranja na trgu finančnih instrumentov v ZDA in Sloveniji. Nedavna manipulacije delnice GameStopa, ki je bila aprila 2020 vredna le 2,80 dolarja, po ravnanju špekulantov na forumu Reddit pa se je njen tečaj povzpel za skoraj 700 odstotkov, je opozorila na sivo cono v pravnem sistemu ZDA. Ravnanje odpira vprašanje, ali dogovarjanje na spletnih forumih, kot je Reddit, sploh izpolnjuje znake kaznivega dejanja tržne manipulacije in ali bi morali moderatorji spletnih forumov omejiti tovrstno komunikacijo. Trenutno veljavna zakonodaja EU za razliko od ZDA deluje preventivno pred prenapihnjenostjo tečajev delnic s samodejnimi sistemi. Ti namreč začasno ustavijo trgovanje z vrednostnimi papirji, ki na seji narastejo za 10 odstotkov, in nato spet pri prirastu za 5 odstotkov. Vendar varovala niso vedno dovolj, pomembna je tudi učinkovita in jasna zakonodaja, ki odvrača tovrstno manipulacijo in varuje celovitost trga finančnih instrumentov.This paper undertakes a comprehensive examination of existing criminal legislation in the United States and Slovenia governing the burgeoning technological threat of market manipulation in light of the escalating cyber threats on online platforms. The GameStop stock incident with surge stock price, from a mere $2.80 in April 2021 to an astounding 700 percent increase, as orchestrated by speculators on the Reddit forum, has illuminated ambiguities within the US legal landscape. This incident prompts a critical inquiry into whether activities such as collusion on online platforms like Reddit can be construed as market manipulation and the potential role of forum moderators in overseeing user behaviour. The GameStop scenario highlights the shifting dynamics of financial markets in the digital age, where traditional frameworks struggle to keep abreast of the sophisticated strategies employed by technologically adept players. The swift dissemination of information on online platforms muddles the distinction between authentic market sentiment and orchestrated manipulation. The anonymity afforded by electronic communication, the vastness of cyberspace, and rapid technological progress create an environment conducive to the emergence of innovative financial technologies and tactics for market manipulation
The impact of reduced working hours on employee productivity and satisfaction
Get PDFV diplomskem delu smo raziskovali, kako skrajšan delovni čas vpliva na zadovoljstvo in produktivnost zaposlenih ter na ravnovesje med poklicnim in zasebnim življenjem. Diplomska naloga se osredotoča na zaposlene v zasebnem sektorju, ki opravljajo administrativna in pisarniška dela. Glavni namen raziskave je bil ugotoviti, ali bi krajši delovnik prispeval k višji produktivnosti in boljšemu zadovoljstvu zaposlenih.
V teoretičnem delu smo predstavili definicije in ključne pojme, povezane z delovnim časom, zadovoljstvom in produktivnostjo zaposlenih. V empiričnem delu smo izvedli anketno raziskavo, s katero smo primerjali mnenja zaposlenih, ki delajo po običajnem 8-urnem delovnem urniku, in tistimi, ki delo opravljajo po skrajšanem delovnem času.
Rezultati raziskave so pokazali, da večina anketirancev verjame, da bi skrajšanje delovnega časa pozitivno vplivalo na njihovo zadovoljstvo in učinkovitost pri delu. Prav tako se je izkazalo, da krajši delovnik omogoča boljše usklajevanje zasebnega in poklicnega življenja, vendar le ob dobri organizaciji dela.
Na podlagi raziskave lahko zaključimo, da skrajšan delovni čas predstavlja pomemben korak k boljšemu ravnovesju poklicnega in zasebnega življenja ter močno vpliva tudi na zaposlene in njihovo zadovoljstvo pri delu, kar se posledično izraža tudi na produktivnosti.In this thesis, we explored how reduced working hours affect employee satisfaction and productivity, as well as the balance between professional and private life. The focus of the thesis is on employees in the private sector who perform administrative and office work. The main aim of the research was to determine whether a shorter workday would contribute to higher productivity and greater employee satisfaction.
In the theoretical part, we presented definitions and key concepts related to working hours, job satisfaction, and employee productivity. In the empirical part, we conducted a survey to compare the opinions of employees working a standard 8-hour schedule with those working reduced hours.
The results of the study showed that most respondents believe that shortening the working day would have a positive effect on their satisfaction and work performance. It was also found that a shorter schedule allows for better reconciliation of private and professional life, but only with good work organization.
Based on the research, we can conclude that reduced working time represents an important step toward achieving a better work-life balance and has a strong impact on employees and their job satisfaction, which in turn positively affects productivity
Artificial intelligence in international marketing communication
Get PDFUspešna komunikacija v mednarodnem okolju zahteva razumevanje kulturnih razlik, vrednot in komunikacijskih stilov. Sodobni komunikacijski kanali, kot so internet, družbena omrežja in drugih digitalni mediji, omogočajo hitro in široko širitev informacij, vendar hkrati zahtevajo medijsko pismenost in občutljivost za kulturni kontekst. Pri mednarodnem trženju je potrebno upoštevati različna pravila in norme glede promocijskih aktivnost, ki se med državami močno razlikujejo. Učinkovito komuniciranje zahteva poznavanje lokalnih značilnosti ter sposobnost prilagajanja vsebin in pristopov specifičnim trgom.
Sodobno trženje je vse bolj digitalno, kar zahteva uporabo naprednih tehnologij, kot so umetna inteligenca, podatkovna analitika in personalizacijska orodja. Digitalno komuniciranje omogoča interaktivnot, hitro odzivanje, personalizacijo sporočil ter pristop, ki združuje fizične in digitalne točke stika s potrošniki. Postavljajo se različna etična vprašanja, kot so varovanje podatkov, transparentnost in soglasje uporabnikov, postajajo vse pomembnejša, saj vplivajo na zaupanje in lojalnost potrošnikov.
Umetna inteligenca postaja osrednji element digitalnega trženja, saj omogoča napredno analizo podatkov, avtomatizacijo procesov, prediktivno modeliranje ter generiranje vsebin. Uporablja se v različnih fazah trženja in prispeva k boljši učinkovitosti, večji angažiranosti potrošnikov in dolgoročni konkurenčni prednosti podjetij. Ob tem umetna inteligenca vpliva tudi na mednarodno trgovino, saj prispeva k večji produktivnost, zmanjševanju stroškov, premagovanju jezikovnih ovir in optimizaciji dobavnih verig. Kljub pomislekom glede vpliva na zaposlovanje, raziskave kažejo, da tehnologija večinoma nadomešča rutinska dela in povečuje človeško učinkovitost.
Glede na pridobljene rezultate vidimo, da večina slovenskih MSP, ki izvažajo na tuj trg, še ne uporabljajo umetne inteligence v podjetju. Razlogi za neuporabo so različni, od nezaznavanja potreb po uprabi, do specifičnosti branže in trga ter omejevanje uporabe umetne ingelince zaradi korporacijskih pravil. Preostanek podjetij uporablja umetno inteligenco v vsaj enem izmed oddelkov v podjetju, kjer najpogosteje uporabljajo generativni AI oziroma ChatGPT, Google orodja z AI ter pomoč pri avtomatizaciji e-poštnih sporočil.Succesfull communication in an international environment requires an understanding of cultural differences, values and communication styles. Modern communication chanels, such as the internet, social media and other digital media, enable fast and widespread dissemination of information, but they also require media literacy and sensitivity to cultural context. In international marketing, it is important to consider different rules and norms regarding promotional activities, which can vary significantly between countries. Effective communication requires knowledge of local specifics and the ability to adapt content and approaches to particular markets.
Modern marketing is increasing digital, which demands the use of advanced technologies such as artificial intelligence, data analytics and personalization tools. Digital communication allows for interactivity, rapis responsivness, message personalization and an approach that integrates both physical and digital customer touchpoints. Various ethical concerns are becoming increasingly imporntant, such as data protection, user consent and transparency, as they directly impact consumer trust and loyalty.
Artificial intelligence is becoming a central element od digital marketing, enabling advenced data analysis, process automation, predictive modeling and content generation. It is used across various stages of marketing and contributes to higher efficiency, greater consumer engagement and long-term competitive advantage. AI also influences international trade by improving productivity, reducin costs, overcoming language barriers and optimazing supply chains. Despite concerns about its impact on employment, research shows that technology primarly replaces routine tasks and increases human efficiency.
Based od the findings, most Slovenian SMEs exporting to foreign markets still do not use artificial intelligence in their operations. The reasons for this vary – from lach of perceived need, to the specificity of their industry and market, or restrictions on AI use due to corporate policies. The remaining companies use AI in at least one department, most commonly relying on generative AI such as ChatGPT, Google AI tools and automation support for email communication
The disappearance of landscape in the drawings and graphics of France Mihelič
Get PDFVsestranski slovenski umetnik France Mihelič (1907–1998) je zapustil bogat in raznolik opus del v najrazličnejših likovnih tehnikah. Največjo grafično in risarsko zbirko Miheličevih del hranijo v Grafičnem kabinetu Franceta Miheliča, ki deluje pod okriljem Pokrajinskega muzeja Ptuj - Ormož. Zbirko več kot šest tisoč risb in grafik je z donacijo družine Musek leta 2024 obogatilo nadaljnjih 189 del iz umetnikovega zgodnjega obdobja. S sistematičnim pregledom Miheličeve zapuščine smo ugotovili, da se je umetnikovo upodabljanje krajine na risbah in grafikah skozi leta bistveno spreminjalo od realističnega do fantazijskega prikaza, v poznejših delih pa je pokrajina skoraj popolnoma izginila. Umetnostni zgodovinarji so se doslej posvečali zlasti raziskovanju umetnikove figuralike, medtem ko je bil motiv izginevanja pokrajine v pregledih Miheličevega opusa pogosto spregledan. Pričujoče delo skuša zapolniti ta manko v razumevanju umetnikovega opusa in sprememb v njem. Upodabljanje in postopno izginevanje pokrajine je postavljeno v kontekst umetnikovega študija na zagrebški akademiji, vpliva profesorjev in starejših ter sočasnih umetnikov, in Miheličevega srečanja s pustnimi običaji. Zlasti pa sta izpostavljeni najpomembnejši prelomnici, ki sta vplivali na umetnikovo delo, to sta neposredno doživetje strahot druge svetovne vojne in študijski obisk Pariza, po katerem je bilo umetnikovo ustvarjanje zaznamovano s fantastiko. V magistrskem delu je s kronološkim pregledom ter metodama analize in interpretacije prikazan umetnikov prehod iz realnega v domišljijski svet. Posebej je prikazano upodabljanje pokrajine, ki vsebinsko postaja vedno manj pomembna, saj je Mihelič za prikazovanje motivov in pripovedovanje ne potrebuje več. V magistrskem delu so prvič predstavljene tudi nekatere risbe in grafike, ki jih je Grafični kabinet Franceta Miheliča na Ptuju pridobil z donacijo družine Musek. Izbrane risbe in grafike, ki so osnova za razlago, analizo in interpretacijo vsebine, so predstavljene v kataloškem delu.The versatile Slovenian artist France Mihelič (1907– 1988) left a rich and varied opus of works in a wide range of artistic techniques. The largest collection of Mihelič’s graphic and drawing works is stored in the Graphic Cabinet of France Mihelič, which operates under the auspices of the Ptuj – Ormož Regional Museum. The collection of more than six thousand drawings and graphics was enriched by a further 189 works from the artist’s early period, donated by the Musek family in 2024. Through a systematic review of Mihelič’s legacy, we found that the artist’s depiction of landscape in his drawings and graphics changed significantly over the years, from realistic to fantastic, while in his later works the landscape completely disappeared. Art historians have so far focused on the artist’s figuration, while the motif of the disappearance of landscape has often been overlooked in reviews of Mihelič’s opus. This work seeks to fill this gap in the understanding of the artist’s opus and the changes in it. The depiction and gradual disappearance of the landscape is set in the context of the artist’s studies at the Zagreb Academy, the influence of his professors, older people, other artists, and Mihelič’s encounter with carnival customs. In particular, the most important turning points that influenced the artist’s work are highlighted, namely the direct experience of the horrors of the Second World War and his study visit to Paris, after which the artist’s work was marked by fantasy. The master’s thesis presents the artist’s transition from the real world to the world of the imagination through a chronological review and methods of analysis and interpretation. In particular, the depiction of landscape, which is becoming less and less important in terms of content, is shown, as Mihelič no longer needs it to depict motifs and narrate. The master’s thesis also presents for the first time some of the drawings and graphics that were acquired by the Graphic Cabinet of France Mihelič in Ptuj, through a donation from the Musek family. Selected drawings and graphics, which form the basis for the explanation, analysis, and interpretation of the content, are presented in the catalogue part

V teoretičnem delu so predstavljene temeljne značilnosti managementa, njegove osnovne funkcije in vrste, pri čemer so posebej izpostavljene posebnosti športnega managementa, ki ga od klasičnih oblik upravljanja ločujejo specifični cilji, velika dinamičnost delovanja ter udeležba različnih deležnikov. Izvedena analiza obravnava ključne deležnike, procese odločanja in organizacijske izzive, s katerimi se sooča obravnavani klub pri managementu.
V empiričnem delu je izvedena poglobljena analiza managementa Rokometnega kluba Jeruzalem Ormož, pri čemer so uporabljeni teoretični modeli, primerjave z drugimi športnimi organizacijami in pridobljeni empirični podatki. Rezultati kažejo, da klub kljub svoji majhnosti in omejenim virom ohranja stabilno organizacijsko strukturo, močno povezanost z lokalnim okoljem ter jasno strategijo razvoja mladih kadrov. Med glavnimi izzivi izstopata geografska lokacija, ki omejuje dostop do širšega trga in sponzorskih priložnosti, ter omejena finančna sredstva, ki otežujejo izvajanje razvojnih projektov.
Ugotovitve potrjujejo, da lahko z učinkovitim managementom, jasno vizijo ter predanostjo vseh deležnikov klub dosega nadpovprečne rezultate in ohranja konkurenčnost v slovenskem prostoru. Predlagane so rešitve, ki vključujejo krepitev dolgoročne finančne stabilnosti, profesionalizacijo organizacijskih procesov, širitev marketinških aktivnosti, boljšo izrabo sodobnih tehnologij in nadaljnje povezovanje z lokalnim ter širšim športnim okoljem.The thesis examines the field of sports management, with a focus on the organizational and managerial operations of a professional handball club. The theoretical part presents the fundamental characteristics of management, its main functions and types, with special emphasis on the specifics of sports management, which differ from traditional forms of management in terms of specific objectives, dynamic operations, and the role of various stakeholders. The analysis addresses key stakeholders, decision-making processes, and organizational challenges faced by the studied club.
The empirical part provides an in-depth analysis of the management of the Jeruzalem Ormož Handball Club, using theoretical models, comparisons with other sports organizations, and collected empirical data. The results show that despite its small size and limited resources, the club maintains a stable organizational structure, strong ties with the local community, and a clear strategy for developing young talent. The main challenges include its geographical location, which limits access to larger markets and sponsorship opportunities, and limited financial resources, which hinder the implementation of broader development projects.
Findings confirm that with effective management, a clear vision, and the dedication of all stakeholders, the club can achieve above-average results and remain competitive in the Slovenian sports environment. Proposed solutions include strengthening long-term financial stability, professionalizing organizational processes, expanding marketing activities, making better use of modern technologies, and further connecting with the local and wider sports community

Odprava otroških porok kot eden od ukrepov za dosego ciljev trajnostnega razvoja do leta 2030
Get PDFChildren are one of the most vulnerable groups of people due to their young age and immaturity, and as such they receive special protection in all areas. This is reflected in the extensive legal protection provided in several international instruments and national laws. One of the indicators that countries and international organizations are taking steps to protect them is also the 2030 Agenda for Sustainable Development, which was launched in 2015 by the Member States of the United Nations out of the multiannual »let\u27s change the world« vision. It sets out 17 goals and actions to improve the world, with children as an important target group. A key action in the light of child protection is the elimination of harmful practices, covered by the Gender Equality Goal, which, among other things, aims to eradicate all harmful practices by 2030, such as child marriage, which have a strong impact on children, (mostly) girls, as they affect several aspects of the lives of »child brides« and could help achieve several Sustainable Development Goals.Zaradi svoje mladosti in nezrelosti so otroci ena najbolj ranljivih skupin ljudi ter kot taki prejemajo posebno zaščito na vseh področjih. To se odraža v obsežni pravni zaščiti, zagotovljeni v večih mednarodnih instrumentih in nacionalnih zakonih. Eden od kazalnikov, da države in mednarodne organizacije sprejemajo ukrepe za zaščito otrok, je tudi Agenda 2030 za trajnostni razvoj, ki so jo leta 2015 začele izvajati članice Združenih narodov. Agenda 2030 določa 17 ciljev in ukrepov za izboljšanje sveta, pri čemer so otroci pomembna ciljna skupina. Ključno dejanje v luči zaščite otrok je odprava škodljivih praks, ki jo pokriva cilj enakosti spolov, ki med drugim cilja na izkoreninjenje vseh škodljivih praks do leta 2030, kot so na primer otroške poroke, ki močno vplivajo na otroke, (večinoma) dekleta, saj vplivajo na več vidikov življenja "otroških nevest" in bi lahko pomagale pri doseganju več trajnostnih ciljev razvoja
Ciljno usmerjeno oglaševanje in (otrokova) pravica do zasebnosti – ex-ante in ex-post sredstva predhodnega in poprejšnjega urejanja
Get PDFThis paper analyses how instruments of economic regulation can be used to protect the right to the protection of personal data, especially in relation to vulnerable societal groups, such as children. In this regard, it analyses the Bundeskartellamt’s Facebook decision that established an unprecedented connection between competition law and data protection law, as well as the Digital Markets Act, which imposes several positive and negative obligations on companies branded as “gatekeepers,” which could also increase the level of personal data protection. It is concluded that instruments of economic regulation can have a profound impact on data protection issues, although addressing them is not their primary goal.V prispevku je analizirano, kako lahko instrumenti ekonomske regulacije prispevajo k zaščiti pravice do varstva osebnih podatkov, še posebej glede na ranljive družbene skupine, kot so otroci. V tem kontekstu je analizirana odločitev Bundeskartellamta v zvezi s Facebookom, ki je vzpostavila brezprimerno povezavo med konkurenčnim pravom in pravom varstva podatkov, ter \u27Digital Markets Act\u27, ki podjetjem, označenim kot »varuhi vrat«, nalaga več pozitivnih in negativnih obveznosti, ki bi lahko tudi povečale raven varstva osebnih podatkov. Ugotavljamo, da lahko instrumenti ekonomske regulacije močno vplivajo na vprašanja varstva podatkov, čeprav to ni njihov primarni cilj
