DEVELOPMENT OF SALES SKILLS
No full textProdaja predstavlja ključni segment svake organizacije jer se pomoću nje ostvaruju prihodi i dobivaju povratne informacije potrebne za daljnji nastavak proizvodnje. Zanimanje prodavača je bilo i još uvijek je jedno od najtraženijih poslova. Kroz ovaj rad vidljivo je kako se prodaja uvijek prilagođavala razvoju društva i potrebama kupaca. Začeci prodaje vidljivi su kroz razdoblje čitave antike, ali i prije nje dok još nije postojao novac kao sredstvo plaćanja zbog čega je razmjena bila znatno otežana. Kada se govori o razvoju vještine prodaje u modernom dobu njen začetak se nalazi u Sjedinjenim Američkim Državama. Razlog tome je znatno drugačija okolina i situacija koja je ondje vladala u odnosu na europsko tlo. Postojala su velika industrijska poduzeća koja su zapošljavala veliki broj prodavača. Počele su se razvijati moderne tehnike prodaje i educirati prodavači kako pristupiti potencijalnim kupcima i uvjeriti ih na kupnju. Aktivnosti i poimanje prodaje znatno se razlikovalo ovisno o eri u kojoj je prodaja djelovala. Svoj vrhunac doživjela je na prijelazu u dvadeseto stoljeće kada više nije bila promatrana kao umjetnost već kao znanstvena disciplina kojoj se tako treba i posvetiti. Pojavom interneta i novih tehnologija u suvremenom dobu došlo je do još bržih i drastičnijih promjena i razvoja prodaje koje su dobrim dijelom smanjile troškove poslovanja, ali i otvorile nova pitanja i mogućnosti.Sales is a key segment of any organization, as it generates income and provides feedback necessary for further production. The profession of salesperson was and still is one of the most sought-after jobs. Through this work, it is evident how sales have always adapted to the development of society and the needs of customers. The beginnings of sales are visible throughout the entire period of antiquity, but also before that, when money did not yet exist as a means of payment, which made exchange significantly more difficult. When it comes to the development of sales skills in the modern era, its origins lie in the United States of America. The reason for this is the significantly different environment and situation that prevailed there compared to European soil. There were large industrial companies that employed large numbers of salespeople. Modern sales techniques began to be developed and salespeople were educated on how to approach potential customers and convince them to buy. The activities and understanding of sales varied significantly depending on the era in which it operated. It reached its peak at the turn of the twentieth century, when it was no longer viewed as an art but as a scientific discipline to which it should be dedicated. The advent of the internet and new technologies in the modern era has led to even faster and more drastic changes and developments in sales, which have largely reduced business costs, but also opened up new questions and opportunities

No full textOvaj završni rad bavi se istraživanjem koncepta zelene maloprodaje, koji sve više postaje aktualan u trgovinskom sektoru zbog svoje ekološke i društvene odgovornosti. Cilj rada je analizirati važnost primjene zelenih strategija u maloprodaji te njihovu ulogu u smanjenju negativnog utjecaja na okoliš, uz istovremeno povećavanje konkurentske prednosti poduzeća. Rad također istražuje kako zelena maloprodaja potiče promjene u potrošačkim navikama i doprinosi ciljevima održivog razvoja. Ključna spoznaja rada jest da zelena maloprodaja nije samo alat za očuvanje okoliša, već i poslovna strategija koja omogućuje dugoročnu ekonomsku korist poduzećima. Kroz analizu poslovanja „dm-a“ kao hrvatskog primjera zelene maloprodaje, prikazano je kako implementacija održivih praksi poput ekoloških proizvoda, recikliranih pakiranja i podrške lokalnoj proizvodnji može stvoriti ravnotežu između društvene odgovornosti i poslovnog uspjeha. Zaključno, zelena maloprodaja se ističe kao ključni smjer budućeg razvoja trgovinskog sektora, spajajući ekološke vrijednosti s konkurentnošću poduzeća te pružajući pozitivan doprinos gospodarstvu i okolišu.This thesis explores the concept of green retail, which is increasingly gaining relevance in the retail sector due to its ecological and social responsibility. The aim of the paper is to analyze the importance of implementing green strategies in retail and their role in reducing negative environmental impacts while simultaneously enhancing the competitive advantage of businesses.

A key insight of the paper is that green retail is not merely a tool for environmental conservation but also a business strategy that enables long-term economic benefits for companies. Through an analysis of "dm" as a Croatian example of green retail, the paper demonstrates how the implementation of sustainable practices, such as eco-friendly products, recycled packaging, and support for local production, can create a balance between social responsibility and business success. In conclusion, green retail stands out as a key direction for the future development of the retail sector, combining ecological values with business competitiveness while providing a positive contribution to the economy and the environment
THE IMPACT OF BEHAVIORAL ECONOMIC PRINCIPLES ON STUDENT'S SELECTION OF HIGHER EDUCATION INSTITUTIONS
No full textOvaj diplomski rad bavi se istraživanjem utjecaja bihevioralne ekonomije na proces donošenja odluke prilikom odabira visokoobrazovne institucije. Bihevioralna ekonomija, koja proučava kako psihološki, društveni i emocionalni čimbenici utječu na ekonomske odluke, pruža korisne alate za razumijevanje studentskog ponašanja pri odabiru fakulteta. Kroz teorijsku analizu i kvantitativno istraživanje provedeno putem online ankete, cilj je bio utvrditi koji čimbenici, poput preporuka obitelji i prijatelja, reputacije institucije, dostupnosti studentskih prava, mogućnosti zapošljavanja nakon studija, ali i osobni dojam te „efekt stada“, najviše utječu na donošenje odluke. Rezultati istraživanja pokazali su kako većina ispitanika ne donosi odluku isključivo racionalno, već pod utjecajem kombinacije emocionalnih i društvenih čimbenika. Istaknuto je da dugoročne pogodnosti, poput mogućnosti zaposlenja i osobnog razvoja, predstavljaju ključne elemente prilikom odabira institucije. Također, velik broj studenata naveo je da bi njihova odluka bila drugačija da su raspolagali s više informacija o drugim institucijama. Ova analiza doprinosi boljem razumijevanju obrazaca ponašanja studenata u kontekstu visokog obrazovanja i može poslužiti donositeljima odluka u obrazovnom sustavu za oblikovanje učinkovitijih strategija privlačenja budućih studenata.This thesis explores the influence of behavioral economics on the decision-making process when choosing a higher education institution. Behavioral economics, which examines how psychological, social, and emotional factors affect economic decisions, offers useful tools for understanding student behavior in the context of university selection. Through theoretical analysis and a quantitative study conducted via an online survey, the aim was to determine which factors,such as family and peer recommendations, institutional reputation, availability of student benefits, employability prospects, as well as personal impressions and the “herd effect”, most influence decision making. The results indicate that most respondents do not make decisions solely rationally but are influenced by a combination of emotional and social factors. Long-term benefits, such as employability and personal development opportunities, emerged as the most important elements when choosing an institution. Additionally, a significant number of students stated that their decision might have differed had they had more information about other institutions. This analysis contributes to a deeper understanding of student behavior patterns in the context of higher education and can assist policymakers in developing more effective strategies for attracting prospective students
ECONOMIC AND FINANCIAL ANALYSIS OF INVESTMENT PROJECTS USING THE EXAMPLE OF CONSTRUCTION OF A GARAGE IN THE CITY OF SPLIT
No full textTema ovog rada je ekonomsko-financijska analiza investicijskog projekta izgradnje javne garaže u Splitu. U kontekstu sve većih potreba za infrastrukturnim rješenjima u urbanim sredinama, projekt izgradnje garaže predstavlja odgovor na prometne izazove te nedostatak parkirnih kapaciteta. Analizom su obuhvaćeni ključni elementi procjene investicije: struktura ulaganja, izvori financiranja, uvjeti kredita, otplata duga, amortizacija, proračun troškova te procjena profitabilnosti. Uz izradu financijskog i ekonomskog novčanog toka te dinamičku ocjenu investicije (NPV, IRR, MIRR), utvrđeno je da projekt ne ostvaruje pozitivnu neto sadašnju vrijednost u promatranom razdoblju te se s financijskog aspekta ne pokazuje isplativim bez dodatnih potpora ili povećanja prihoda. Međutim, s aspekta javnog interesa i poboljšanja prometne dostupnosti, projekt ima potencijalnu društvenu vrijednost.The topic of this thesis is the economic and financial analysis of an investment project for the construction of a public parking garage in the city of Split. In light of increasing demand for infrastructural solutions in urban areas, the garage construction project addresses key traffic challenges and the lack of parking capacity. The analysis includes essential components of investment evaluation: investment structure, sources of financing, credit conditions, loan repayment, amortization, cost estimation, and profitability assessment. Through the preparation of financial and economic cash flows and the application of dynamic evaluation methods (NPV, IRR, MIRR), the project was found not to generate a positive net present value over the observed period and, from a financial perspective, is not profitable without additional subsidies or increased revenues. However, in terms of public interest and improved traffic accessibility, the project has clear potential for social value
WIRELESS POWER TRANSFER (WPT)
No full textU završnom radu obrađuje se tema bežičnog prijenosa energije, tehnološkog koncepta modernizacije postojećeg načina distribucije i korištenja električne energije. U početku se polazi od povijesnog razvoja ideje bežičnog prijenosa s naglaskom na rad i viziju Nikole Tesle koji je krajem 19. stoljeća postavio temelje bežičnog prijenosa. U suvremenom razvoju, kroz istraživanja važnu primjenu imaju i tehnologije elektromagnetske indukcije, mikrovalnog i laserskog prijenosa. Rad sustavno analizira tehničke strane navedenih tehnologija, njihovu učinkovitost, potencijalne primjene, prednosti i ograničenja. Naglasak je na tehničkim i ekološkim izazovima, koji ograničavaju implementaciju ovih tehnologija, pa se razmatraju rješenja koja uključuju primjenu naprednih materijala, antena i rezonantnih sustava. Razmatra se inovativni pristup poput kvazistatičke rezonantne šupljine, prijenos putem ambijentalnih radio frekvencijskih izvora te mogućnosti prijenosa energije na veće udaljenosti pomoću rezonantnih zavojnica. Dakle, bežični prijenos energije predstavlja perspektivno područje za istraživanje koje u narednim godinama može značajno unaprijediti elektroenergetski sustav. Unatoč nedostacima, tehnološkim napretkom moguće je potaknuti široku komercijalnu primjenu i pridonijeti održivom razvoju energetske budućnosti.This final thesis addresses the topic of wireless power transfer (WPT), a technological concept aimed at modernizing the existing methods of distributing and using electrical energy. It begins with a historical overview of the development idea of wireless power transfer, with a focus on the work and vision of Nikola Tesla, who laid the foundations for wireless transmission at the end of the 19th century. In modern development, technologies such as electromagnetic induction, microwave transmission, and laser transmission have gained significant importance through research. The thesis systematically analyzes the technical aspects of these technologies, their efficiency, potential applications, advantages, and limitations. Emphasis is placed on the technical and environmental challenges that limit the implementation of these technologies, with a discussion of possible solutions involving advanced materials, antennas, and resonant systems. Innovative approaches are considered, such as quasistatic resonant cavities, energy transfer via ambient radio frequency sources, and the possibility of long-distance transmission using resonant coils. Thus, wireless power transfer represents a promising field of research that could significantly improve the power system in the coming years. Despite its drawbacks, technological advancements may enable widespread commercial application and contribute to the sustainable development of the future of energy

CHARACTERISTICS OF CROATIAN INVESTORS IN THE CRYPTOCURRENCY MARKET
No full textKriptovalute predstavljaju relativno novu, ali sve značajniju formu financijskog tržišta, koja privlači pažnju ulagača diljem svijeta, pa tako i u Hrvatskoj. Za razliku od tržišta dionica, gdje se profil ulagača već godinama sustavno istražuje i jasno definira, tržištu kriptovaluta još uvijek nije dato dovoljno pažnje u literaturi, posebno u hrvatskom kontekstu. S obzirom na uočenu prazninu u znanstvenoj i stručnoj literaturi, ovaj rad napravljen je s ciljem stjecanja cjelovite slike o karakteristikama ulagača u kriptovalute, uključujući njihove socio-demografske osobine, investicijske strategije, motive ulaganja, percepciju rizika i reakcije na tržišne promjene. Da bi se postigao cilj rada provedeno je kvantitativno istraživanje metodom anketnog upitnika u online formi u kojem je sudjelovalo 120 ispitanika. Rezultati pokazuju da u Hrvatskoj u kriptovalute ulažu dominantno muškarci, mlađe do srednje životne dobi, visokoobrazovani te s primanjima na srednjoj do visokoj razini. Na investicijske odluke u visokom mjeri utječe fenomen krda, a za ulazak u svijet kriptovaluta dominantno ih motivira potencijal visokog povrata na uloženo. Ulagači su većinom svjesni rizika od volatilnosti koje kriptovalute sa sobom nose, no to ih ne sprječava da su unatoč pretrpljenim gubicima, većinom ustrajni u namjeri da i u budućnosti nastave s ulaganjima.Cryptocurrencies represent a relatively new but increasingly significant form of financial market, attracting the attention of investors worldwide, including in Croatia. In contrast to the stock market, where investor profiles have been systematically researched and clearly defined for years, the cryptocurrency market remains insufficiently explored, particularly in the Croatian context. Given this gap in scientific and professional literature, the research presented in this paper was conducted with the aim of gaining a comprehensive understanding of the characteristics of Croatian cryptocurrency investors, including their socio-demographic traits, investment strategies, investment motives, risk perception, and reactions to market changes. To achieve this objective, quantitative research was conducted through an online survey questionnaire, in which 120 respondents participated. The results show that cryptocurrency investors in Croatia are predominantly men, young to middle-aged, highly educated, and with medium to high income levels. Investment decisions are strongly influenced by herd behavior, and the main motivation for entering the world of cryptocurrencies is the potential for high returns on investment. Most investors are aware of the risks and volatility associated with cryptocurrencies, yet this does not prevent them, despite experiencing losses, from remaining persistent in their intention to continue investing in the future
THE POSSIBILITIES OF USING THE TIKTOK SOCIAL NETWORK FOR PROMOTING COSMETIC BRANDS
No full textOd pojave društvenih mreža, komunikacija među ljudima doživjela je značajne promjene. Društvene mreže nude raznovrsne usluge, među kojima je i povezivanje ljudi putem interneta. U današnje vrijeme društvene mreže postale su jedne od glavnih načina oglašavanja i komunikacije s ciljnom publikom. Iako prvotno percipirana kao isključivo platforma zabavnog tipa, u praksi se pokazala kao digitalni alat koji pomoću kreiranja korisnog i zabavnog sadržaja može pridonijeti povećanju svijesti o brendu, potaknuti interakciju i angažiranost kupca s brendom, te posljedično povećati volumen prodaje tvrtke. Ovaj rad pruža čitateljima analizu i prikaz promotivnih strategija kojima se brendovi služe na platformi TikTok. Provedba navedenih promotivnih strategija prikazana je kroz brend L`Oreal Paris.Since the advent of social networks, communication among people has undergone significant changes. Social networks provide a wide range of services, including connecting people via the Internet. Nowadays, social media has become one of the main platforms for advertising and communicating with the target audience. Although initially perceived as exclusively an entertainment platform, in practice it has proven to be a digital tool that, through the creation of useful and entertaining content, can contribute to increasing brand awareness, encouraging customer interaction and engagement with the brand, and consequently increasing the company's sales volume. This paper provides readers with an analysis and overview of the promotional strategies used by brands on the TikTok platform. The implementation of these promotional strategies is illustrated through the brand L'Oréal Paris
