Comparative analysis of the effectiveness of algorithms for finding the optimal path in the Unity development environment
No full textOvaj diplomski rad istražuje implementaciju i optimizaciju algoritama za pronalaženje optimalnog puta unutar Unity platforme. Fokus je stavljen na A*, Dijkstra i flood fill algoritme, čije su performanse uspoređene kroz niz kvantitativnih eksperimentalnih scenarija u dinamičnim virtualnim okruženjima. Analizirane su tehnike poput optimizacije putem hrpe, uglađivanje puta, višedretvenog izvođenja i uvođenja težinskih mapa, s ciljem poboljšanja učinkovitosti i skalabilnosti sustava navigacije. Rezultati pokazuju da pažljivo odabrane optimizacije mogu značajno unaprijediti brzinu izvođenja i kvalitetu putanje, čime se doprinosi razvoju realističnijih i responzivnijih sustava kretanja unutar računalnih igara.This master’s thesis investigates the implementation and optimization of optimal path finding algorithms within the Unity platform. The focus is on A*, Dijkstra and flood fill algorithms, whose performance is quantitatively compared through a series of experimental scenarios in dynamic virtual environments. Techniques such as heap optimization, path smoothing, multi-time execution and the introduction of weight maps were analyzed, with the aim of improving the efficiency and scalability of the navigation system. The results show that carefully selected optimizations can significantly improve execution speed and trajectory quality, thus contributing to the development of more realistic and responsive movement systems within computer game
Creativity and potentially gifted children in early and preschool education
No full textTema ovog završnog rada je „Kreativnost i potencijalno darovita djeca u ranom i predškolskom odgoju i obrazovanju“. Suvremene definicije darovitosti obrađene su u teorijskom dijelu i one uključuju višestruke oblike inteligencije, motivaciju i kreativnost koji su važni čimbenici u identifikaciji darovite djece. Spominju se najznačajniji pristupi kao što je na primjer Gardnerova teorija višestrukih inteligencija i Renzullijeva troprstenska definicija darovitosti, koje nam zajedno pomažu prikazati širi okvir kako bi se lakše razumjele sposobnosti djece. Glavni dio rada temelji se na prepoznavanju karakteristika darovite djece u ranom i predškolskom razdoblju, metode koje se koriste za poticanje kreativnosti (konvergentno i divergentno mišljenje) – simboličke igre, igre likovnog izražavanja i igre neverbalne komunikacije. U redu su prikazani i konkretni primjeri aktivnosti i igara koje su namijenjene za poticanje kreativnosti kod djece. Program „Baltazar“ koji se provodi u dječjem vrtiću „Mali svijet“ u Puli pravi je primjer uspješne prakse koja se provodi u radu s djecom. Provedbom intervjua s odgajateljicom Vedranom Sanković dobiven je uvid u provođenje programa, koje su konkretne metode, izazovi i prednosti rada s darovitom djecom u direktnoj praksi. Za sam kraj provodi se zaključak koji se temelji na tome da su rano prepoznavanje i sustavna podrška prijekopotrebni za razvoj dječjeg potencijala, a glavni alat u tom procesu je kreativnost.The topic of this final paper is "Creativity and Potentially Gifted Children in Early Childhood and Preschool Education." The theoretical part explores contemporary definitions of giftedness, which include multiple forms of intelligence, motivation, and creativity—important factors in identifying gifted children. Significant approaches are discussed, such as Gardner's theory of multiple intelligences and Renzulli's three-ring conception of giftedness, which together help present a broader framework for better understanding children's abilities.The main part of the paper focuses on recognizing the characteristics of gifted children in early and preschool age, as well as methods used to foster creativity (convergent and divergent thinking)—including symbolic play, visual expression activities, and nonverbal communication games. Concrete examples of activities and games aimed at encouraging children's creativity are also presented. The "Baltazar" program, implemented at the "Mali svijet" kindergarten in Pula, serves as a successful example of good practice in working with children. An interview conducted with educator Vedrana Sanković provided insight into the implementation of the program, specific methods used, challenges encountered, and the benefits of working directly with gifted children. Finally, the conclusion emphasizes that early identification and systematic support are crucial for developing a child's potential, with creativity being the main tool in this process
Redesign of the brand and the corresponding product - Kraš and Životinjsko carstvo : Research and practical application
No full textOvaj završni rad bavi se analizom procesa redizajna vizualnog identiteta, s naglaskom na proizvode koji imaju dugogodišnju prisutnost na tržištu i prepoznatljivost temeljenu na tradiciji i nostalgičnoj vrijednosti. Teorijski dio rada obuhvaća pojašnjenje osnovnih pojmova iz područja grafičkog dizajna, vizualnog identiteta i procesa redizajna. U okviru rada provedeno je istraživanje s ciljem dobivanja uvida u percepciju javnosti o redizajnu općenito te o trenutačnom vizualnom identitetu proizvoda Kraš Životinjsko Carstvo. Rezultati istraživanja ukazuju na to da potrošači često izražavaju negativne stavove prema drastičnim promjenama vizualnog identiteta, osobito kada su povezane s emocionalno važnim brendovima. U umjetničkom dijelu rada izrađen je prijedlog novog vizualnog rješenja ambalaže čokoladica Životinjsko Carstvo, s ciljem očuvanja njihove prepoznatljivosti, ali i unaprjeđenja dizajna kako bi bio suvremeniji i vizualno atraktivniji. Prilikom izrade redizajna uzeti su u obzir rezultati istraživanja te osnovni principi grafičkog dizajna.This thesis focuses on the topic of redesigning visual identity, with particular emphasis on the redesign of products rooted in long-standing tradition and nostalgic value. The theoretical part explains basic concepts in graphic design, visual identity, and the redesign process. A survey was conducted to gain insight into public perception of redesign in general, as well as the current visual identity of the Kraš Životinjsko Carstvo product. The research results indicate that consumers often express negative attitudes towards drastic changes in visual identity, especially when associated with emotionally significant brands. The artistic part of the thesis presents a proposal for a new packaging design for the Životinjsko Carstvo chocolates, aiming to preserve their recognizability while enhancing the design to be more modern and visually appealing. The redesign process took into account the research findings and fundamental principles of graphic design

Inflation and unemployment in Croatia: an analysis in the EU context
No full textInflacija i nezaposlenost dvije su ključne makroekonomske varijable koje oblikuju gospodarsku stabilnost. U razdobljima ekonomske ekspanzije, kada inflacija raste zbog povećane potražnje, stopa nezaposlenosti obično opada. Međutim, tijekom inflacijskih šokova, poput onih uzrokovanih energetskom krizom i poremećajima u lancima opskrbe, učinci na nezaposlenost mogu varirati ovisno o reakciji monetarne politike i fleksibilnosti tržišta rada. Istovremeno, tržište rada pokazuje otpornost uz povijesno nisku nezaposlenost, što može signalizirati strukturalne promjene ili kašnjenje učinaka monetarnih mjera. U Hrvatskoj je vidljivo postupno prilagođavanje tržišta rada u kontekstu eurozone, no dugoročni izazovi, poput niske produktivnosti i demografskih trendova, ostaju ključni rizici. Sukladno tome, ovaj rad istražuje povezanost inflacije i nezaposlenosti uspoređujući dinamiku promjena između tih varijabli u Hrvatskoj tijekom vremena, s posebnim naglaskom na razdoblje od 2008. do 2023. godine. Dodatno se evaluiraju zaključci s podacima za EU. Cilj rada je empirijski analizirati odnos inflacije i nezaposlenosti u Hrvatskoj primjenom statističkih podataka i ekonometrijskih metoda, s naglaskom na postojanje i stabilnost njihove korelacije te usporedbu s europskim trendovima radi utvrđivanja stupnja usklađenosti hrvatskog gospodarstva s EU. Analiza sugerira kako su kretanja inflacije i nezaposlenosti u EU i Hrvatskoj poprilično slična te da Hrvatska u velikoj mjeri prati opće europske trendove inflacije, uz određena manja odstupanja što potvrđuje postavljenu hipotezu rada kako kretanje inflacije i nezaposlenosti u Hrvatskoj u razdoblju od 2008. do 2023. godine pokazuje značajnu korelaciju s kretanjima tih varijabli u EU, uz određena manja odstupanja.Inflation and unemployment are two key macroeconomic variables that shape economic stability. During periods of economic expansion, when inflation rises due to increased demand, the unemployment rate typically declines. However, during inflationary shocks—such as those caused by energy crises and supply chain disruptions—the effects on unemployment may vary depending on monetary policy responses and labor market flexibility. At the same time, the labor market demonstrates resilience, with historically low unemployment, which may indicate structural changes or delayed effects of monetary measures. In Croatia, a gradual labor market adjustment within the eurozone framework is evident, yet long-term challenges such as low productivity and demographic trends remain key risks.
Accordingly, this paper examines the relationship between inflation and unemployment by comparing the dynamics of these variables in Croatia over time, with a particular focus on the period from 2008 to 2023. Additionally, conclusions are evaluated in relation to EU data. The objective of this study is to empirically analyze the relationship between inflation and unemployment in Croatia by applying statistical data and econometric methods, emphasizing the existence and stability of their correlation, as well as comparing them with European trends to determine the degree of alignment of the Croatian economy with the EU. The analysis suggests that inflation and unemployment trends in the EU and Croatia are largely similar and that Croatia closely follows general European inflationary trends, with some minor deviations. This confirms the research hypothesis that inflation and unemployment trends in Croatia between 2008 and 2023 exhibit significant correlation with those in the EU, with certain minor discrepancies
The usefullness of prisoner's dilemma in the implementation of market interactions: an analysis on the example of Adidas and Nike companies
No full textCilj ovog diplomskog rada jest utvrditi korisnost zatvorenikove dileme u implementaciji tržišnih interakcija konkurenata u okviru određene industrije, što će se u ovom slučaju analizirati na primjeru kompanija Adidas i Nike. Istraživanje je provedeno na tri razine: financijska analiza, strateška analiza te modeliranje interakcija pomoću teorije igara. Komparativnom analizom trendova grafičkih prikaza, analizom financijskih izvještaja, metodama analize i sinteze te deduktivnom metodom dolazi se do zaključaka koji potvrđuju tri hipoteze na kojima počiva rad.
Zaključci upućuju na izuzetnu uspješnost provođenja strategija promatranih kompanija kako bi kontinuirano održavale vrh svjetske scene sportske industrije, nešto bolje implementiranje strategija od strane kompanije Nike u odnosu na Adidas, što rezultira većim godišnjim prihodima za kompaniju Nike, te na činjenicu kako znanje principa zatvorenikove dileme kompanijama može uvelike pomoći u planiranju i provedbi tržišnih interakcija s konkurentima, rezultirajući boljim ishodom.
Rad pridonosi literaturi ukazujući na značaj teorije igara u donošenju strateških odluka, te nudi preporuke za učinkovitije menadžersko upravljanje u situacijama tržišnih interakcija.The goal of this Master's thesis is to determine the usefulness of Prisoner's dilemma in the implementation of market interactions of competitors within a certain industry, which will in this case be analysed on the example of Adidas and Nike. The research is done on three levels: finantial analysis, strategic analysis, and modeling interactions with the help of Game theory. Using compariative analysis of trends shown on graphic representations, analysis of finantial reports, methods of analysis and synthesis and deduction methods, three hypothesis of the Master's thesis are confirmed.
Conclusions point to the exceptional success of the implementation of strategis of the observed companies in order to remain at the top of global sporting goods industry scene, somewhat better implementation of strategies by Nike compared to Adidas, which results in higher annual revenues for the mentiond company, and the fact that knowledge of principles of the Prisoner's dilemma can greatly help companies in planning and implementing interacions with competitors, resulting a better outcome.
The paper contributes to the literature by pointing out the importance of Game theory in strategic decision – making, and offers reccomendations for more effective managerial management in situations of market interactions

No full textSAŽETAK
Uvod: Ambliopija (slabovidnost) je najčešći uzrok smanjenog vida u djece i vodeći uzrok monokularne sljepoće u odrasloj dobi. Rano otkrivanje i liječenje ključni su za uspješnu rehabilitaciju vida. U Hrvatskoj se od 2018. provodi Nacionalni program probira ambliopije u dobi od četiri godine, s planiranim trajanjem do 2028.
Cilj: Cilj ovog istraživanja bio je analizirati rezultate probira slabovidnosti kod četverogodišnje djece u Općoj bolnici Pula, s posebnim naglaskom na prevalenciju i težinu ambliopije te razlike prema spolu.
Metode: Retrospektivno istraživanje provedeno je od 10. rujna 2022. do 24. svibnja 2025. u dječjoj oftalmološkoj ambulanti OB Pula. U istraživanje su uključena djeca u dobi od četiri godine iz Istarske županije. Vidna oštrina ispitivana je LEA tablicama, monokularno i binokularno.
Rezultati: Poziv na probir dobilo je 3040 djece, a odazvalo se 1927 (63,4%). Ambliopija je otkrivena kod 602 djece (31,2%). Od toga je blaga ambliopija zabilježena u 41,6%, umjerena u 39,2% i teška u 19,2% slučajeva. Ambliopija je podjednako bila zastupljena kod djevojčica (n=303) i dječaka (n=299), bez statistički značajne razlike u težini.
Zaključak: Prevalencija ambliopije među četverogodišnjacima u Istarskoj županiji značajno je viša od većine svjetskih podataka. Rezultati upućuju na potrebu kontinuiranog provođenja nacionalnog programa i dodatne edukacije roditelja i zdravstvenih djelatnika s ciljem povećanja odaziva i učinkovitosti ranog otkrivanja.SUMARRY
Introduction: Amblyopia is the most common cause of visual impairment in children and a leading cause of monocular blindness in adulthood. Early detection and treatment are crucial for successful visual rehabilitation. Croatia has implemented a National Amblyopia Screening Program for four-year-olds from 2018 to 2028.
Aim: The aim of this study was to analyze the results of amblyopia screening in four-year-old children at Pula General Hospital, focusing on prevalence, severity, and gender distribution.
Methods: A retrospective study was conducted from September 10, 2022, to May 24, 2025, at the pediatric ophthalmology clinic of Pula General Hospital. The study included four-year-old children from the Istria County. Visual acuity was assessed using LEA charts, both monocularly and binocularly.
Results: Out of 3040 invited children, 1927 participated (63.4%). Amblyopia was diagnosed in 602 children (31.2%). Of these, 41.6% had mild amblyopia, 39.2% moderate, and 19.2% severe. Amblyopia was equally present in girls (n=303) and boys (n=299), with no statistically significant difference in severity.
Conclusion: The prevalence of amblyopia among four-year-olds in Istria County is significantly higher compared to international data. These findings highlight the need for sustained implementation of the national screening program and improved education for parents and healthcare professionals to enhance participation and early detection rates
