Bit će navedeni i korišteni pravni izvori koji reguliraju postupak posvojenja u Republici Hrvatskoj kao što su Ustav Republike Hrvatske, Međunarodni ugovori, Konvencija o pravima djeteta i Konvencija o zaštiti djece i suradnji u vezi s međudržavnim posvojenjem, Obiteljski zakon te ostali pravilnici i izvori. Detaljnije će biti objašnjene pretpostavke koje su važne za zasnivanje postupka posvojenja. Jedna od ključnih stavki u postupku posvojenja je uloga Hrvatskog zavoda za socijalni rad čije će se dužnosti detaljnije opisati, uz poseban osvrt na prava djeteta uključujući pravo na pristup informacijama o posvojenju te pravo na izražavanje vlastitog mišljenja. Također, važni su pristanci u postupku posvojenja od osoba na koje posvojenje proizvodi pravne učinke. Postupak posvojenja će biti detaljno opisan. U nastavku će biti objašnjeni procjena podobnosti i prikladnosti za posvojenje te sam postupak posvojenja. Kao poglavlje koje bi zatvorilo cjelinu posvojenja, bit će objašnjeni pravni učinci posvojenja, pravo nasljeđivanja te prednosti i nedostatci posvojenja u Republici Hrvatskoj. Za istraživanje ove teme koristit će se anketa provedena na odabranom uzorku sudionika, s ciljem dobivanja uvida u njihova mišljenja i stavove o posvojenju u suvremenoj Republici Hrvatskoj. Također, s pomoću statističke metode bit će obrađeni pojedini podatci o broju posvojenja u Republici Hrvatskoj te na temelju komparativne metode bit će prokomentirane sličnosti i različitosti instituta posvojenja u pojedinim državama. Na kraju rada nalazi se zaključak, popis literature i priloga koji su korišteni u radu.The paper will explain in more detail what adoption is and what its purpose is. Legal sources that regulate the adoption procedure in the Republic of Croatia will be listed and used, such as the Constitution of the Republic of Croatia, international treaties, the Convention on the Rights of the Child and the Convention on Protection of Children and Cooperation in Respect of Intercountry Adoption, the Family Law and other regulations and sources. The assumptions that are important for establishing the adoption procedure will be explained in more detail. One of the key items in the adoption procedure is the role of the Croatian Institute for Social Work, whose duties will be described in more detail, with special reference to the rights of the child - including the right to access information about adoption and the right to express one's own opinion. Also, consents in the adoption procedure from persons on whom the adoption produces legal effects are important. The adoption procedure will be described in detail. The assessment of suitability and appropriateness for adoption and the adoption procedure itself will be explained below. As a chapter that would close the adoption unit, the legal effects of adoption, inheritance rights, and the advantages and disadvantages of adoption in the Republic of Croatia will be explained. To research this topic, a survey conducted on a selected sample of participants will be used, with the aim of gaining insight into their opinions and attitudes about adoption in the contemporary Republic of Croatia. Also, using statistical methods, certain data on the number of adoptions in the Republic of Croatia will be processed, and based on the comparative method, the similarities and differences of the adoption institute in individual countries will be commented on.

Influence of physical activity on the incidence of non-specific back pain among students on the Faculty of dental medicine and health Osijek
No full textCilj istraživanja: Utvrditi povezanost između tjelesne aktivnosti i pojavnosti nespecifičnog
bola u leđima kod studenata Fakulteta za dentalnu medicinu i zdravstvo u Osijeku, uzimajući u
obzir učestalost i intenzitet tjelesne aktivnosti, spol i dob ispitanika.
Nacrt studije: Presječno istraživanje u kojem su analizirani podaci prikupljeni putem anketnog
upitnika kako bi se ispitala povezanost između učestalosti i intenziteta tjelesne aktivnosti te
percepcije njezina utjecaja na zdravlje leđa.
Ispitanici i metode: U istraživanju je sudjelovalo 133 studenata svih smjerova i godina studija
Fakulteta za dentalnu medicinu i zdravstvo u Osijeku. Podaci su prikupljeni putem online
ankete, a statistička analiza uključivala je deskriptivne metode, Hi-kvadrat test, korelacijsku i
regresijsku analizu.
Rezultati: Rezultati su pokazali da studenti koji se redovito bave tjelesnom aktivnošću rjeđe
prijavljuju nespecifični bol u leđima dok učestalost izvođenja specifičnih vježbi za jačanje
mišića trupa nije pokazala značajnu povezanost s percepcijom koristi tjelesne aktivnosti za
zdravlje leđa. Povezanost između tjelesne aktivnosti i bola u leđima varirala je s obzirom na
spol i dob, ali nije bila statistički značajna.
Zaključak: Tjelesna aktivnost može imati pozitivan učinak na smanjenje nespecifičnog bola u
leđima, ali nije jedini čimbenik koji utječe na njezinu pojavnost. Potrebna su daljnja istraživanja
kako bi se preciznije utvrdili ključni čimbenici koji doprinose prevenciji i upravljanju bola u
leđima kod studentske populacije.Objectives: To determine the relationship between physical activity and the prevalence of
nonspecific back pain among students of the Faculty of Dental Medicine and Health in Osijek,
considering the frequency and intensity of physical activity, gender, and age of the participants.
Study design: A cross-sectional study in which data collected through a survey questionnaire
were analyzed to examine the relationship between the frequency and intensity of physical
activity and the perception of its impact on back health.
Subjects and methods: The study involved 133 students from all programs and years of study
at the Faculty of Dental Medicine and Health in Osijek. Data were collected through an online
survey, and statistical analysis included descriptive methods, the Chi-square test, correlation,
and regression analysis.
Results: The results showed that students who engage in regular physical activity report
nonspecific back pain less frequently, while the frequency of performing specific trunk muscle
strengthening exercises did not show a significant correlation with the perception of the benefits
of physical activity for back health. The relationship between physical activity and back pain
varied based on gender and age, but was not statistically significant.
Conclusion: Physical activity may have a positive effect on reducing nonspecific back pain,
but it is not the only factor influencing its prevalence. Further research is needed to more
precisely identify the key factors contributing to the prevention and management of back pain
in the student population

by inputing basic data into the program
Modernization of Sekeli Goulash
No full textU ovom radu poseban osvrt je na jednom od poznatih jela mađarske kuhinje sekeli gulašu, poznat kao Szekely gulaš koji se udomaćio i u našoj kuhinji. Cilj rada je proučiti sekeli gulaš, zatim ga pripremiti prema tradicionalnom receptu te ga na jedan način osuvremeniti. Priređeni gulaš će biti senzorski ocijenjen uz pomoć nekoliko studenata. Ocjenjivanjem je utvrđeno da se dodavanjem nečeg novog u jedno tradicionalno jelo ipak dobije novo ukusno jelo koje senzoričarima stvara pomutnju u odluci koje je jelo bolje.This paper focuses on one of the famous dishes of Hungarian cuisine, the Szekely goulash, known as Szekely goulash. The aim of the paper is to study the Szekely goulash, then prepare it according to a traditional recipe and modernize it in a way. The prepared goulash will be sensory evaluated with the help of several students. The evaluation determined that adding something new to a traditional dish still results in a new, delicious dish that creates confusion for sensory experts in deciding which dish is better
Testing of asphalt mixture using samples from the Cestorad d.d. Vinkovci asphalt plant
No full textU ovom završnom radu prikazana je proizvodnja i kontrola asfaltne mješavine na asfaltnoj bazi „Cestorad Vinkovci“. Proizvodnja na asfaltnoj bazi „Cestorad“ je diskontinuiranog tipa te se proizvodi asfalt po vrućem postupku. Kontrola kvalitete je važna od samog procesa proizvodnje asfaltne mješavine pa sve do njegove upotrebe. Laboratorijske provjere kontrole kvalitete materijala, postupci uzorkovanja materijala, priprema uzoraka asfaltne mješavine, provjera topljivog uzorka veziva, određivanje granulometrijskog sastava, određivanje gustoće asfaltne mješavine, određivanje gustoće asfaltnog uzorka, određivanje šupljina asfaltnog uzorka i provjera dimenzija asfaltnog uzorka. U građevinarstvu je obavezno primjenjivati propise, pravilnike i pridržavati se normi standarda za materijala koji se određuje u pomoćnom laboratoriju koji je smješten neposredno uz sam pogon asfaltne baze.This final paper examines the production and quality control of asphalt mixtures at the "Cestorad Vinkovci" asphalt plant. Production at the asphalt plant "Cestorad" is of a discontinuous type, utilizing a hot-mix process for asphalt production. Quality control plays a crucial role throughout the entire process, from the initial production of the asphalt mixture to its final application. Laboratory quality control encompasses several key procedures, including material testing, material sampling procedures, preparation of asphalt mixture samples, checking of soluble binder samples, determination of granulometric composition, determination of asphalt mixture density, determination of asphalt sample density, determination of asphalt sample voids and checking of asphalt sample dimensions. In construction practice, strict adherence to established regulations and standards is mendatory. These standards, particularly those concerning materials, are verified in an auxiliary laboratory located next to the asphalt plant
Estimation of compressive strength of self-compacting concrete with mineral admixtures using destructive and non-destructive methods
No full textSamozbijajući beton je suvremena vrsta betona, nastao zbog nedovoljnog broja radne snage. Predstavlja napredno rješenje u građevinarstvu jer omogućuje kvalitetnije popunjavanje oplata i armature bez dodatne vibracije, čime se postiže bolja ujednačenost i viša kvaliteta izvedenog betona. Dodavanjem mineralnih dodataka poput letećeg pepela, silicijske prašine ili troske, poboljšavaju se mehanička i trajnosna svojstva betona, no pritom dolazi do promjene u njegovom sastavu, što utječe na karakteristike čvrstoće. Uz mineralne dodatke, koriste se i različiti kemijski dodatci. Primjenom samozbijajućeg betona povećava se ukupna kvaliteta i trajnost konstrukcija, uz dodatni doprinos očuvanju okoliša. Glavni cilj ovog istraživanja bio je utvrditi povezanost između razornih i nerazornih metoda kako bi se pouzdanije procijenila tlačna čvrstoća samozbijajućeg betona s različitim vrstama mineralnih dodataka. Sa svrhom postizanja zadanog cilja, u prvom koraku izrađeno je šest mješavina betona pri čemu je projektiranje sastava samozbijajućeg betona provedeno prema EFNARC (Europsko udruženje) smjernicama za sastav mješavine. Beton je ispitivan u svježem i očvrslom stanju. Ispitivanja u očvrslom stanju provedena su na uzorcima kocki, prizmi, valjaka i jezgri u skladu s hrvatskim normama nakon 7, 28 i 91 dan. Rezultatima eksperimentalnog ispitivanja dokazano je da postotni udio od 10% silicijske prašine znatno poboljšava svojstva samozbijajućeg betona, dok je utjecaj letećeg pepela na rezultate ispitivanja nešto slabiji. Razorna i nerazorna ispitivanja zajedno omogućuju potpunu procjenu kvalitete betona, posebno
nerazorne metode, poput ultrazvučne brzine impulsa i digitalnog sklerometra. Na temelju dobivenih rezultata moguće je razviti korisne regresijske modele za procjenu tlačne čvrstoće samozbijajućeg betona.Self-compacting concrete is a modern type of concrete developed in response to a shortage of labor. It represents an advanced solution in construction because it enables better filling of formwork and reinforcement without additional vibration, thereby achieving greater uniformity and higher quality of the finished concrete. By adding mineral additives such as fly ash, silica fume, or slag, the mechanical and durability properties of the concrete are improved, although this leads to changes in its composition, which in turn affects strength characteristics. In addition to mineral additives, various chemical admixtures are also used. The use of self-compacting concrete increases the overall quality and durability of structures, while also contributing to environmental preservation. The main objective of this research was to determine the correlation between destructive and nondestructive testing methods in order to more reliably assess the compressive strength of self-compacting concrete with different types of mineral additives. To achieve the stated goal, six concrete mixtures were
produced in the first step, with the mix design of the self-compacting concrete carried out according to EFNARC (European Federation) guidelines. The concrete was tested in both fresh and hardened states.Tests in the hardened state were performed on cube, prism, cylinder, and core samples in accordance with Croatian standards after 7, 28, and 91 days.
The results of the experimental testing confirmed that a 10% share of silica fume significantly improves the properties of self-compacting concrete, while the influence of fly ash on test results is somewhat weaker. Destructive and non-destructive testing together provide a comprehensive assessment of concrete quality, especially non-destructive methods such as ultrasonic pulse velocity and digital rebound hammer. Based on the obtained results, it is possible to develop useful regression models for estimating the compressive strength of self-compacting concrete

Data were analysed using the Mann-Whitney U test, Kruskal-Wallis test, as well as Pearson’s chi-square test to examine correlations between variables.
Results: The importance of early intervention and their future professional role was rated highly by students. However, they reported a lower self-assessment of their practical knowledge, particularly in the application of specific therapeutic methods, such as MAES, sensory integration, and robotic rehabilitation. Statistically significant differences in self-assessment were found according to gender, age and level of study, with graduate students reporting a higher level of competence. Open-ended responses indicated that students perceived practical assessment, communication with parents and professional responsibilities as the most challenging.
Conclusion: The results indicate that practical content and clinical training in the field of early intervention require strengthening. It is important to promote the development of transdisciplinary competencies and to ensure the integration of theoretical knowledge and clinical practice in order to provide better preparation of students for their professional work
Ion Exchange Protein Chromatography
No full textIonoizmjenjivačka kromatografija je tehnika odvajanja komponenti smjese koja se zasniva na razdjeljivanju proteina temeljenog na neto površinskom naboju, a same interakcije kojima odvajamo molekula od interesa određuju se nosačima koje još nazivamo kromatografski medij ili smola. Od osnovnih koraka u ionoizmjenjivačkoj kromatografiji proteina razlikujemo ekvilibraciju, nanošenje uzorka i ispiranje, eluciju i regeneraciju. Ionoizmjenivačka kromatografija nudi visoku rezoluciju, grupno odvajanje s velikim kapacitetom te je također, uz razdvajanje molekularnih vrsta s malom razlikom u svojstvima naboja, bitna također i za pročišćavanje proteina, peptida, nukleinskih kiselina i drugih nabijenih molekula. Svojstva ionske kromatografije, izbor medija, optimalni uvjeti rada te načini odvajanja i druge bitne karakteristike, detaljnije su objašnjeni u ovom završnom radu.Ion exchange chromatography is a technique for separating the components of a mixture, which is based on the separation of proteins based on net surface charge, and the interactions by which separated molecules of interest are determined by carrier (chromatographic media, resin) properties. Among the basic steps in protein ion exchange chromatography, we distinguish equilibration, sample application and wash, elution and regeneration. Ion exchange chromatography offers high-resolution, high-capacity group separation and, in addition to the separation of molecular species with a small difference in charge properties, it is also essential for the purification of proteins, peptides, nucleic acids and other charged molecules. Properties of ion exchange chromatography, choice of media, optimal working conditions and methods of separation and other important characteristics are explained in more detail in this undergraduate thesis
