Contagion effect between fiat currency and cryptocurrency

Ovaj rad istražuje fenomen financijske zaraze, definirane kao povećanje povezanosti među tržištima nakon financijskog šoka, s fokusom na odnose između kriptovaluta i fiat valuta. S obzirom na globalnu povezanost ekonomija, razumijevanje širenja zaraze i njezinog utjecaja na financijsku stabilnost postaje sve važnije. Kriptovalute, kao novi financijski instrumenti, mogu značajno utjecati na globalne financijske tokove, čime istraživanje njihove povezanosti s fiat valutama postaje važnije. Iako se kriptovalute smatraju rizičnim investicijama, njihova uloga kao zaštitne imovine, diversifikatora ili sigurnog utočišta može varirati ovisno o tržišnim uvjetima. Istraživanje se temelji na dnevnim podacima o cijenama Bitcoina i Ethereuma te indeksa fiat valuta USD-a, EUR-a i GBP-a u razdoblju od 2.1.2019. do 3.1.2023., s naglaskom na promjene prije i nakon početka pandemije COVID-19. Korištenjem DCC-MGARCH modela analizirane su dinamičke uvjetne korelacije dnevnih prinosa, dok je Kolmogorov-Smirnov test korišten za ispitivanje prisutnosti zaraze. Rezultati su pokazali da su Bitcoin i Ethereum prije pandemije imali slabu negativnu korelaciju s USD-om, djelujući kao zaštita, dok su tijekom pandemije postali sigurnija utočišta. Prema EUR-u, korelacija je ostala blizu nule, što ih također pozicionira kao zaštitu. U odnosu na GBP, pokazali su slabe pozitivne korelacije, čineći ih diverzifikatorima. Kolmogorov-Smirnov testovi su otkrili su dominaciju kriznog razdoblja nad pretkriznim za parove EUR-ETH, GBP-BTC i GBP-ETH, što ukazuje na prisutnost zaraze između ovih valuta. GBP-BTC je pokazao najizraženiju zarazu, dok su EUR-ETH i GBP-ETH imali manje izražene razlike u distribucijama, sugerirajući blagu zarazu. Suprotno tome, za parove USD-BTC, USD-ETH i EUR-BTC nije pronađena zaraza.This paper explores the phenomenon of financial contagion, defined as the increased interconnectedness among markets following a financial shock, with a focus on the relationships between cryptocurrencies and fiat currencies. Given the global interconnectedness of economies, understanding the spread of contagion and its impact on financial stability is becoming increasingly important. Cryptocurrencies, as new financial instruments, can significantly influence global financial flows, making the study of their connection with fiat currencies more crucial. The research is based on daily price data of Bitcoin and Ethereum, as well as fiat currency indices USD, EUR, and GBP, from January 2, 2019, to January 3, 2023, with an emphasis on changes before and after the onset of the COVID-19 pandemic. Using the DCC-MGARCH model, dynamic conditional correlations of daily returns were analyzed, while the Kolmogorov-Smirnov test was used to examine the presence of contagion. The results showed that before the pandemic, Bitcoin and Ethereum had a weak negative correlation with USD, acting as a hedge, while during the pandemic, they became safer havens. Against EUR, the correlation remained close to zero, also positioning them as a hedge. In relation to GBP, they exhibited weak positive correlations, making them diversifiers. The Kolmogorov-Smirnov tests revealed the dominance of the crisis period over the pre-crisis period for the pairs EUR-ETH, GBP-BTC, and GBP-ETH, indicating the presence of contagion. GBP-BTC showed the most pronounced contagion, while EUR-ETH and GBP-ETH had less pronounced distribution differences, suggesting mild contagion. Conversely, no contagion was found for the pairs USD-BTC, USD-ETH, and EUR-BTC

Conservation and restoration procedures on mosaic fragments from the collection of the Archaeological Museum in Split

U stražnjem dvorištu Arheološkog muzeja u Splitu nalazi se značajna količina arheološkog materijala, koja je u taj prostor smještena radi privremene ili trajne pohrane, u očekivanju konzervatorsko-restauratorskih zahvata ili jednostavno zbog ostvarenja sigurnijih uvjeta nego što bi to bilo moguće ostvariti na izvornim lokalitetima. U određenim slučajevima, suvremeni je život Salone uzrokovao uništenje nekih lokaliteta, ili slučajne pronalaske artefakata tijekom poljodjelskih radova, pa su istraživači, ravnatelji muzeja, ili muzejski kustosi otkupljivali nalaze i pohranjivali ih u muzej. Među tim materijalom posebnu pozornost konzervatora-restauratora privuklo je trinaest paleta s ulomcima mozaika kojima je bila potrebna hitna intervencija zbog izrazito lošeg stanja - bili su prekriveni mahovinom, borovim iglicama i smolom, određeni su se ulomci prelamali, a njihov teselatum se odvajao od podloge. Ova znatna količina materijala predstavljala je izazov u svakom pogledu, počevši od nedostatka izvorne povijesne dokumentacije o njihovom porijeklu i okolnostima njihovog dopremanja u muzej, pa sve do planiranja budućih restauratorskih radova na svakom pojedinom ulomku, odgovarajućeg načina pohrane i eventualne prezentacije. Premda je hitna, preliminarna intervencija na tim mozaicima započela je prije nekoliko godina, kada je glavnina materijala dokumentirana i kataloški obrađena, dok pitanja konzervacije i prezentacije nisu razriješena, te je svakim tjednom bilo vidljivo narušavanje stanja, odnosno cjelovitosti ulomaka mozaika. Zbog izrazito nepovoljnih uvjeta čuvanja u dvorištu sub divo, mozaici su prebačeni u dislocirano skladište (depo) Arheološkog muzeja u Solinu, kako bi se olakšala priprema za konzervatorsko-restauratorske radove. Premještanjem u depo započela je njihova detaljna konzervatorsko – restauratorska obrada, uključujući čišćenje, spajanje ulomaka i izradu privremenih podloga. Ovi su zahvati omogućili njihovo primjereno čuvanje i značajno usporili njihovo propadanje, čime su stvoreni preduvjeti za njihovo buduće istraživanje i prezentaciju, posebno u svjetlu mogućnosti pronalaska novih ulomaka ili podataka o njihovom porijeklu.In the backyard of the Archaeological Museum in Split, there is a significant amount of archaeological material, placed in this space for temporary or permanent storage, awaiting conservation-restoration interventions, or simply due to the need for safer conditions than could be provided at the original sites. In certain cases, the modern life of Salona caused the destruction of some sites, or accidental discoveries of artifacts during agricultural works, leading researchers, museum directors, or museum curators to acquire the finds and store them in the museum. Among this material, special attention from conservators-restorers was drawn to thirteen pallets with mosaic fragments that required urgent intervention due to their extremely poor condition – they were covered with moss, pine needles, and resin; some fragments were breaking apart, and their tessellatum was detaching from the substrate. This substantial amount of material posed a challenge in every respect, starting with the lack of original historical documentation regarding their origin and the circumstances of their transport to the museum, all the way to planning future restoration work on each individual fragment, finding appropriate storage methods, and potential presentation. Although an urgent, preliminary intervention on these mosaics began several years ago, when the majority of the material was documented and cataloged, the questions of conservation and presentation remained unresolved, and the deterioration, i.e., the fragmentation of the mosaic pieces, became more evident each week. Due to extremely unfavorable storage conditions in the open-air courtyard, the mosaics were transferred to an off-site storage facility (depot) of the Archaeological Museum in Solin, to facilitate preparation for conservation-restoration works. With the move to the depot, their detailed conservation-restoration treatment began, including cleaning, joining fragments, and creating temporary supports. These measures enabled their proper preservation and significantly slowed down their deterioration, creating the conditions necessary for their future research and presentation, especially in light of the possibility of discovering new fragments or data about their origin

Effect of UV-C radiation on protein interaction between KRAS and RAF1 RAS binding domain

Cilj : Svrha ovog rada je opisati i razjasniti kako oksidacija utječe na funkcionalne posljedice interakcije KRAS i RBD (RAF1 RAS-vezna domena) proteina. Metode: Korištenjem HEK293 stanica, proizvedeni su potrebni proteini za analizu. Nakon analize stanica, proteini su izloženi tretmanu UV-C zračenja. Zatim su određene razne varijante pri kojima su proteini stupali u protein-protein interakcija. Zadnji korak je odraditi Western blot analizu koristeći SIMPL metodu gdje su rezultati vidljivi na filmu pomoću metode kemiluminiscencije. Rezultati: Proteini su tretirani raznim dozama UV-C zračenja. Nakon što je uočeno da pri početno postavljenim dozama tretmana, 0.05 J/cm2 i 0.3 J/cm2 , nema vidljivih promjena u interakcijama između proteina, određene su nove doze: 0.4 J/cm2 , 0.6 J/cm2 , 0.8 J/cm2 i 1.0 J/cm2 . Pri dozama od 0.4 J/cm2 i 0.6 J/cm2 nema vidljivih promjena u inerakcijama između proteina. Pri dozi 0.8 J/cm2 , vidljivo je smanjenje intenziteta proteinske vrpce kada su KRAS i RBD proteini tretirani. Krajnja doza zračenja korištena u ovom eksperimentu je 1.0 J/cm2 gdje se uočava potpuni gubitak interakcije između tretiranih KRAS i RBD proteina. Dodatna je provedena mjera karbonilacije proteina pri već postavljenim dozama. Uočava se razlika u izgledu proteinske vrpce između netretiranog proteina i proteina tretiranih različitim dozama UV-C zračenja. Također, karbonilacija je ponovljena za doze 0.8 J/cm2 i 1.0 J/cm2 pri čemu je uočeno da proteinska vrpca RBD protein tretiran dozom 1.0 J/cm2 skoro pa potpuno blijedi. Zaključak: Rezultati dobiveni ovim istraživanjem ukazuju na dozno-ovisni učinak UV-C zračenja na interakciju KRAS-RBD. Slabljenje veze, uočeno pri većoj dozi, implicira da oksidacija proteina može utjecati na stabilnost kompleksa. Važno je istaknuti da su proteinske vrpce kontrolnih uzoraka pojedinačnih proteina (netretiranog proteina) bile jednake onima koje su prošle tretman zračenjem, sugerirajući da samo UV-C zračenje nije uzrok promjena u ekspresiji proteina. Dodatna provjera oksidativne štete je pomoću mjerenja razine proteinske karbonilacije, što je pokazalo povećanje oksidativnog oštećenja u tretiranim uzorcima u usporedbi s netretiranim. Ova opservacija podržava ideju da UV-C zračenje uzrokuje oksidaciju proteina, što dalje može utjecati na njihove interakcije.Aim: The purpose of this thesis is to describe and clarify how oxidation affects the functional consequences of the interaction of KRAS and the RBD (RAF1 RAS-binding domain) protein. Methods: The required proteins for analysis were produced using HEK293 cells. After cell lysis, proteins are exposed to UV-C radiation treatment. Then various variants were determined in which the proteins entered into protein-protein interactions. The last step was to perform a Western blot analysis using the SIMPL method where the results are visible on film using the chemiluminescence method. Results: The proteins were treated with various doses of UV-C radiation. After it was observed that at the initially set treatment doses, 0.05 J/cm2 and 0.3 J/cm2 , there were no visible changes in the interactions between proteins, new doses were determined: 0.4 J/cm2 , 0.6 J/cm2 , 0.8 J/cm2 and 1.0 J/cm2 . At doses of 0.4 J/cm2 and 0.6 J/cm2 there are no visible changes in interactions between proteins. At a dose of 0.8 J/cm2 , a decrease in the intensity of the protein band was visible when KRAS and RBD proteins were treated. The final radiation dose used in this experiment is 1.0 J/cm2 where a complete loss of interaction between the treated KRAS and RBD proteins is observed. An additional measure of protein carbonylation was carried out at the already set doses. There is a difference in the appearance of the protein band between the untreated protein and the protein treated with different doses of UV-C radiation. Also, carbonylation was repeated for doses of 0.8 J/cm2 and 1.0 J/cm2 , where it was observed that the protein band RBD protein treated with a dose of 1.0 J/cm2 almost completely fades. Conclusions: The results obtained in this study indicate a dose-dependent effect of UV-C radiation on the KRAS-RBD interaction. The weakening of the bond, observed at the higher dose, implies that protein oxidation may affect the stability of the complex. It is important to point out that the protein bands of control samples of individual proteins (untreated protein) were the same as those that underwent radiation treatment, suggesting that UV-C radiation alone is not the cause of changes in protein expression. Additionally, oxidative damage was checked by measuring the level of protein carbonylation, which showed an increase in oxidative damage in treated samples compared to untreated ones. This observation supports the idea that UV-C radiation causes oxidation of proteins, which can further affect their interactions

Possibilities and Examples of Waste Utilization in Concrete : Master's Thesis

Građevinarstvo stvara velike količine otpada, što zahtijeva učinkovito gospodarenje. Recikliranje građevinskog otpada je ključno za očuvanje resursa i smanjenje zagađenja. Beton je najprodavaniji građevinski materijal na svijetu. Povećana proizvodnja betona utječe na prirodne resurse, okoliš i zahtijeva velike količine energije. Jedan je od najviše korištenih građevinskih materijala, a pokazao se i kao medij u kojeg je moguće ugraditi razne vrste otpada poput industrijskog otpada, reciklirane plastike, recikliranog stakla, otpadnog tekstila i drugih. Proizvodnja cementa stvara visoke količine ugljičnog dioksida, troše se velike količine sirovina te nastaje velika količina otpada. U ovom radu prikazani su neki od recikliranih materijala, njihova svojstva te njihov utjecaj na mehanička svojstva betona i na svojstva svježe betonske mješavine.Construction generates large amounts of waste, requiring efficient management. Recycling construction waste is crucial for conserving resources and reducing pollution. Concrete is the most sold construction material in the world. Increased concrete production affects natural resources, and the environment, and requires large amounts of energy. It is one of the most used construction materials and has proven to be a medium into which various types of waste such as industrial waste, recycled plastic, recycled glass, waste textiles, and others can be incorporated. Cement production generates high amounts of carbon dioxide, large amounts of raw materials are consumed and consequently a large amount of waste is generated. This master's thesis presents some of the recycled materials, their properties, and their impact on the mechanical properties of concrete and the properties of fresh concrete mix

MARICA, TONKA AND IVE - MALE AND FEMALE PERSONAL NAMES IN POP AND POPULAR CROATIAN MUSIC

Od prvih društvenih zajednica do današnjih dana, osobna su imena važan kako društveni tako i leksički, ali i kulturalni koncept. Primarno uvedena kako bi se članovi zajednice međusobno razlikovali postala su važan znak i obilježje pripadnosti i identiteta pojedinca. Veza između imena i pojedinca vrlo je snažna, u nekim kulturama smatrana je i sudbonosnom. Dokaz je tomu i latinska uzrečica Nomen est omen, koja je u hrvatskom jeziku poznatija pod izrazom Ime je znak, upotrebljavana kada se želi naglasiti usklađenost značenja imena s karakternim osobinama osobe koja ga nosi. Kada su, vremenom, društvene zajednice postale sve brojnije i imena nisu bila dovoljna oznaka razlikovanja, osobnim se imenima počinju dodavati nadimci, imena koja nisu službena, već nadjenuta od zajednice u kojoj pojedinac boravi. Ta su imena većinom inspirirana vrlinama i manama pojedinca, njegovim fizičkim obilježjima, mjestom iz kojeg dolazi ili poslom kojim se bavi. Osobni su nadimci prelazili u obiteljske nadimke te konačno u prezimena. U ovom će radu fokus biti na imenima i nadimcima spomenutim u pjesmama izvedenim na Splitskom festivalu u razdoblju od 1962. do 1992.From the first social communities to the present day, personal names are an important social and lexical concept, as well as a cultural concept. Primarily introduced in order to differentiate community members from each other, they have become an important sign and characteristic of individual belonging and identity. The connection between a name and an individual is very strong, in some cultures it is considered fateful. Proof of this is the Latin saying Nomen est omen, which in croatian is better known as the expression Ime je znak, used when one wants to emphasize the harmony of the meaning of the name and the character traits of the person who bears it. When, over time, social communities became more and more numerous and names were not a sufficient mark of distinction, nicknames began to be added to personal names, names that are not official, but given by the community in which the individual resides. These names are mostly inspired by the virtues and flaws of an individual, his physical characteristics, the place he comes from or the work he does. Personal nicknames became family nicknames and finally surnames. In this paper, the focus will be on the names and nicknames mentioned in the songs performed at the Split Festival in the period from 1962 to 1992

Aromatic profile of Ninski šokol : diploma thesis

Ninski šokol je jedinstveni gastronomski proizvod jedinstvene arome, koji ima dugu tradiciju proizvodnje u gradu Ninu i širem okolnom području. Za izradu ninskog šokola vrlo važno je kvalitetno svinjsko meso, ninska sol, razni začini i tradicijski proces proizvodnje. Specifičnosti sirovine, tehnološkog postupka pripreme i zrenja rezultiraju povećanjem koncentracije hlapljivih spojeva arome. Te su komponente proizašle iz biokemijskih procesa prilikom razgradnje masnog, vezivnog i mišićnog tkiva a odgovorne su za specifična okusna i mirisna obilježja ovog proizvoda. Hlapljivi spojevi su izolirani metodom mikroekstrakcije vršnih para na krutoj fazi (HS-SPME), korištenjem triju vlakana različite polarnosti. Izolirani spojevi su analizirani spregnutom tehnikom plinska kromatografija – spektrometrija masa (GC- MS) u cilju usporedbe sličnosti i razlika dobivenih rezultata. Ukupno je identificirano 38 spojeva koji se mogu svrstati u kemijske skupine: aldehide, alkohole, alkane, estere, fenole, masne kiseline i terpene.Ninski šokol is a distinctive gastronomic meat product with an unique aroma, produced for centuries in the town of Nin and its surrounding areas. Its preparation relies on high-quality pork, local salt from Nin, various spices and traditional methods, which are crucial for achieving its distinctive flavor. The specific qualities of the raw materials and the aging process lead to a higher concentration of volatile aromatic compounds. These compounds are result of biochemical processes that occur during the breakdown of fat, connective and muscle tissues, contributing to the unique taste and aroma of the product. The volatile compounds were isolated using headspace solid-phase microextraction (HS- SPME) with three fibers of different polarities. The extracted compounds were analyzed using gas chromatography-mass spectrometry (GC-MS) to compare the similarities and differences in the results. A total of 38 compounds were identified, categorized into the chemical groups such as aldehydes, alcohols, alkanes, esters, phenols, fatty acids, and terpenes, further highlighting the complexity and richness of Ninski šokol

Impact of storage conditions on the aromatic profile of virgin olive oils : bachelor thesis

Maslina (Olea europea) jedna je od najstarijih kultiviranih biljaka i ključna kultura u jadranskom dijelu Hrvatske. Djevičanska maslinova ulja, proizvedena isključivo mehaničkim postupcima tiještenja zdravih plodova masline, izdvajaju se svojim jedinstvenim sastavom i aromom. Hlapljivi spojevi koji se razvijaju tijekom i nakon ekstrakcije ulja značajno doprinose njegovom aromatičnom profilu. Osim berbe i prerade, na kvalitetu maslinovog ulja utječu adekvatna dorada i pravilno skladištenje, što je ključno za očuvanje ulja i zaštitu od štetnih vanjskih utjecaja. Cilj ovog Završnog rada bio je ispitati utjecaj načina čuvanja djevičanskog maslinovog ulja, dobivenog preradom različitih sorti maslina (Oblica, Leccino i Levantinka) ubranih s dva različita lokaliteta, na aromatični profil ulja. Uzroci su čuvani na tri načina: u tamnoj staklenoj boci na suhom i tamnom mjestu, u inox spremniku te u inox spremniku s dušikom u natprostoru. Analize su provedene svako 6 mjeseci u periodu od 18 mjeseci. Iz dobivenih rezultata utvrđeno je da odabir načina čuvanja ima izražen utjecaj na aromatični profil djevičanskih maslinovih ulja. Rezultati svih načina čuvanja ulja pokazali su blagi trend pada hlapljivih spojeva koji se povezuju pozitivnim aromama. Čuvanje ulja u tamnoj staklenoj boci i inox spremnicima s dušikom u natprostoru se pokazalo kao izrazito dobar način čuvanja, naročito za sprječavanja procesa oksidacije. Ulja čuvana u inox spremniku bez korištenja dušika u natprostoru bila su podložnija procesima oksidacije što je rezultiralo povećanim udjelom hlapljivih spojeva koji se povezuju s negativnim aromama ulja.The olive (lat. Olea europea) is one of the oldest cultivated plants and a key crop in the Adriatic region of Croatia. Virgin olive oils, produced exclusively through mechanical processes by pressing healthy olive fruits, stand out due to their unique composition and aroma. The volatile compounds that develop during and after the oil extraction significantly contribute to its aromatic profile. In addition to harvesting and processing, the quality of olive oil is influenced by appropriate refinement and proper storage, which are crucial for preserving the oil and protecting it from harmful external factors. The aim of this thesis was to investigate the impact of storage methods on the aromatic profile of virgin olive oil obtained from the processing of different olive varieties (Oblica, Leccino, and Levantinka) harvested from two different locations. The samples were stored in three different ways: in a dark glass bottle in a dry and dark place, in a stainless steel tank, and in a stainless steel tank with nitrogen in the headspace. Analyses were conducted every six months over a period of 18 months. The results indicated that the choice of storage condition has a significant effect on the aromatic profile of the virgin olive oil. The results of all methods of oil storage showed a slight trend of decreasing volatile compounds associated with positive aromas. Storing the oil in a dark glass bottle and in nitrogen-filled stainless steel tanks proved to be an extremely effective way to preserve the oil, particularly in preventing oxidation processes. In contrast, oils stored in a stainless steel tank without using nitrogen in the headspace were more susceptible to oxidation processes, which resulted in an increased proportion of volatile compounds that are associated with the negative aromas of the oil

Association of lifestyle habits and knowledge with the prevention of microvascular and macrovascualr complications in patients with diabetes mellitus: Cross-sectional study

UVOD: Šećerna bolest (diabetes mellitus) kronična je bolest koja može dovesti do ozbiljnih mikrovaskularnih i makrovaskularnih komplikacija. Ključnu ulogu u prevenciji ovih komplikacija imaju zdrave životne navike, uključujući pravilnu prehranu, tjelesnu aktivnost i higijenu, kao i adekvatna edukacija pacijenata. Medicinsko osoblje, posebice liječnici i medicinske sestre, ima važnu ulogu u pružanju točnih i pouzdanih informacija pacijentima kako bi ih motivirali na pravilnu brigu o vlastitom zdravlju. Kvalitetna edukacija pacijenata može značajno smanjiti rizik od komplikacija i poboljšati njihovu kvalitetu života. CILJ: Glavni cilj ove studije je utvrditi povezanost između životnih navika i znanja o šećernoj bolesti s učestalosti pojave mikravosakularnih i makrovaskularnih komplikacija kod oboljelih od šećerne bolesti. ISPITANICI I METODE: Ova presječna studija provedena je u KBC-u Split kako bi se ispitala povezanost životnih navika i znanja pacijenata sa šećernom bolešću u prevenciji vaskularnih komplikacija. Podaci su prikupljeni anonimnim anketama tijekom hospitalizacije ili pregleda, koristeći upitnike o demografiji, tjelesnoj aktivnosti, prehrani, znanju o bolesti i kvaliteti života. Studiju je odobrilo Etičko povjerenstvo KBC-a Split, a sudjelovanje ispitanika bilo je dobrovoljno i anonimno. REZULTATI: U istraživanju je sudjelovalo 216 ispitanika, pri čemu su osobe s komplikacijama bile statistički značajno starije (p = 0,004), u mirovini (p = 0,011), živjele na otoku (p = 0,034) i imale drugu kroničnu bolest (p = 0,003). Nisu utvrđene statistički značajne razlike u pridržavanju mediteranske prehrane (p = 0,289). Nije uočena povezanost između komplikacija i pušenja (p = 0,180), konzumacije alkohola (p = 0,414) ili tjelesne aktivnosti (p = 0,213), ali je granična značajnost uočena za vrijeme provedeno sjedeći (5,0 ± 2,7 vs. 4,3 ± 2,7 sati dnevno, p = 0,051). Ispitanici bez komplikacija imali su bolje znanje o prehrani (prosječan broj točnih odgovora 4,3 ± 1,5 vs. 3,9 ± 1,6, p = 0,049), dok su ispitanici s komplikacijama bolje prepoznali oštećenja koja nisu povezana sa šećernom bolesti (94,9% vs. 85,7%, p = 0,041). ZAKLJUČAK: Rezultati provedene studije ističu značaj kontinuirane edukacije pacijenata sa šećernom bolesti, s naglaskom na prehranu, tjelesnu aktivnost i identifikaciju rizičnih čimbenika za moguće komplikacije. Edukacijama bi se osiguralo dugotrajno održavanje i poboljšanje znanja, što bi pomoglo u smanjenju rizika od komplikacija i unapređenju kvalitete života oboljelih.INTRODUCTION: Diabetes mellitus is a chronic disease that can lead to serious microvascular and macrovascular complications. Healthy lifestyle habits, including proper nutrition, physical activity, and hygiene, as well as adequate patient education, play a key role in preventing these complications. Healthcare professionals, particularly doctors and nurses, have an important role in providing accurate and reliable information to patients to motivate them to take proper care of their health. Quality patient education can significantly reduce the risk of complications and improve their quality of life. AIM: The main objective of this study is to determine the association between lifestyle habits and knowledge about diabetes with the frequency of microvascular and macrovascular complications in individuals with diabetes. PARTICIPANTS AND METHODS: This cross-sectional study was conducted at the University Hospital Centre Split to examine the relationship between patients' lifestyle habits and knowledge about diabetes in the prevention of vascular complications. Data were collected through anonymous surveys during hospitalization or medical examinations, using questionnaires on demographics, physical activity, diet, knowledge about the disease, and quality of life. The study was approved by the Ethics Committee of the University Hospital Centre Split, and participants took part voluntarily and anonymously. RESULTS: The study included 216 participants, with individuals experiencing complications being significantly older (p = 0.004), more often retired (p = 0.011), living on an island (p = 0.034), and having another chronic disease (p = 0.003). No significant differences were found in adherence to the Mediterranean diet (p = 0.289). There was no observed association between complications and smoking (p = 0.180), alcohol consumption (p = 0.414), or physical activity (p = 0.213), but a borderline significance was noted for time spent sitting (5.0 ± 2.7 vs. 4.3 ± 2.7 hours per day, p = 0.051). Participants without complications had better knowledge about nutrition (average number of correct answers 4.3 ± 1.5 vs. 3.9 ± 1.6, p = 0.049), whereas participants with complications were more likely to recognize conditions unrelated to diabetes (94.9% vs. 85.7%, p = 0.041). CONCLUSION: The study's results highlight the importance of continuing education for patients with diabetes, emphasising nutrition and physical activity, and identifying risk factors for possible complications. Education would ensure long-term maintenance and improvement of knowledge, which would help reduce the risk of complications and improve patient's quality of life

Seismic Analysis of the Medieval Military Dry-stone Masonry Tower Arquà in Italy : Master's Thesis

Za obrambeni suho zidani toranj Arquà koji se nalazi u pokrajini Rovigo, izvršene su analize ponašanja konstrukcije pod utjecajem seizmičkih sila. Za analizu je korišten numerički model Y2D, temeljen na kombiniranoj metodi konačno-diskretnih elemenata. Podloga seizmičkih zapisa uzeta je na temelju stvarnog potresnog događaja u Petrovcu 1979. godine. U radu je prikazano kako veličina blokova i način oslanjanja zidanog tornja utječu na ponašanje konstrukcije pod seizmičkim djelovanjem.For the defensive dry-stone tower of Arquà, located in the province of Rovigo, analyses of the structure's behavior under seismic forces were conducted. The analyses utilized the numerical model Y2D, based on the combined method of finite-discrete elements. The seismic data foundation was obtained from an actual seismic event in Petrovac in 1979. The study demonstrates how the size of blocks and the manner in which the stone tower is supported influence the structure's response to seismic actions
