Influence of reverse osmosis process in different operating conditions on phenolic profile and antioxidant activity of conventional and ecological Cabernet Sauvignon red wine
No full textRed wine polyphenols are responsible for its colour, astringency, and bitterness. They are known as strong antioxidants that protect the human body from the harmful effects of free radicals and prevent various diseases. Wine phenolics are influenced by viticulture methods and vinification techniques, and therefore, conventionally and ecologically produced wines of the same variety do not have the same phenolic profile. Ecological viticulture avoids the use of chemical adjuvants in vineyards in order to minimise their negative influence on the environment, wine, and human health. The phenolic profile and antioxidant activity of wine can also be influenced by additional treatments, such as concentration by reverse osmosis. The aim of this study was to investigate the influence of four different pressures (2.5, 3.5, 4.5, and 5.5 MPa) and two temperature regimes (with and without cooling) on the phenolic profile and antioxidant activity of conventional and ecological Cabernet Sauvignon red wine during concentration by reverse osmosis. The results showed that retention of individual phenolic compounds depended on the applied processing parameters, chemical composition of the initial wine, and chemical properties of a compound. Higher pressure and retentate cooling favoured the retention of total polyphenols, flavonoids, and monomeric anthocyanins, compared to the opposite conditions. The same trend was observed for antioxidant activity
IMAPCT OF COVID 19 PANDEMIC ON CONSUMER BEHAVIOUR
No full textPočetkom 2020. godine svijetom je zavladala globalna pandemija virusa pod nazivom „COVID 19“, budući da nitko nije bio spreman na promijene koje je pandemija donijela „preko noći“ su se mijenjale svakodnevica i život na koji su svi navikli. U trenutcima kad su se donosile sve strože i strože mjere diljem svijeta ponašanje potrošača se značajno promijenilo, od načina kupnje do količina koje su pojedinci kupovali. U provom dijelu ovog rada razrađeno je na koji način su podatci prikupljani i koja je metodologija korištena. Također na samom početku rada amplificirana je tema kako se ponaša kupac u interaktivnom okruženju, te kako prednost interaktivnog okruženja pokušava iskoristiti proizvođač odnosno prodavač proizvoda ili usluge, također objašnjen je pojam koji se odnosi na osobnu potrošnju i kako kultura utječe na potrošača, te koji su još utjecaji na ponašanje potrošača. U slijedećem dijelu rada analizirani su načini utjecaja na potrošača, kao i pojam interneta i online trgovine, temeljem analiza međunarodnih statističkih organizacija prikazan je utjecaj globalne pandemije na internet trgovinu u Europi, te je prikazano u kojim zemljama se najviše kupuje putem interneta. U završnom djelu rada provedeno je empirijsko istraživanje na uzorku od 138 ispitanika, te je analizirano mišljenje ljudi o sigurnosti kupovine na internetu te mišljenje da li su ljudi pretjerano stvarali zalihe za vrijeme pandemije i da li se češće odlučuju na kupovinu putem interneta nego su to radili prije pandemije.At the beginning of 2020, the world was dominated by a global virus pandemic called "COVID 19", since no one was prepared for the changes that the pandemic brought, "overnight" everyday life and the life that everyone was used to changed. In the moments when stricter and stricter measures were adopted around the world, consumer behavior changed significantly, from the way of buying to the quantities that individuals bought. In the first part of this work, it was elaborated how the data were collected and what methodology was used. Also, at the very beginning of the work, the topic of how the customer behaves in an interactive environment is amplified, and how the manufacturer or seller of a product or service tries to take advantage of the interactive environment, the term related to personal consumption and how culture affects the consumer, and which are more influences on consumer behavior. In the next part of the paper, the ways of influencing the consumer, as well as the concept of the Internet and online trade, are analyzed, based on the analysis of international statistical organizations, the impact of the global pandemic on Internet trade in Europe is shown, and it is shown in which countries the most purchases are made via the Internet. In the final part of the paper, empirical research was conducted on a sample of 138 respondents, and people's opinion about the safety of shopping on the Internet was analyzed, as well as the opinion of whether people excessively stockpiled during the pandemic and whether they decide to shop online more often than they used to. before the pandemi

ABC METHOD APPLICATION AND ITS BENEFITS
No full textU ovom radu se ukazuje na primjeru ABC metode u obračunu troškova i njene koristi. ABC metoda je važna u sustavu računovodstva i način na koji raspoređuje izravne i neizravne troškove na objekte proizvodnje (proizvodi i usluge), odnosno pojedinačnom proizvodu se dodjeljuju troškovi koje je on prouzročio, što pomaže razumijevanju kritičkih poslovnih informacija. Za obračun troškova i njene koristi važno je odrediti ključ po kojem će se raspoređivati troškovi na aktivnosti. U radu će se ukratko osvrnuti na vrste troškova te će se uvidjeti koje su razlike između tradicionalnih i suvremenih metoda obračuna troškova i njihove koristi s fokusom na metodu obračuna troškova po aktivnostima, odnosno ABC metoda. ABC metoda obračuna troškova će se primijeniti i izvršiti njena implementacija na postojećem primjeru.This paper points to an example of the ABC method in costing and its benefits. The ABC method is an important method in the accounting system and which allocates direct and indirect costs to production facilities (products and services), ie the individual product is allocated the costs it has caused, which helps to understand critical business information. To calculate costs and its benefits, it is important to determine the key by which costs will be allocated to activities. The paper will briefly describe the types of costs and the differences between traditional and modern methods of costing and their benefits will be shown with a focus on the Activity Based Costing Method, or ABC method. The ABC costing method will be applied and implemented on an existing example
KNOWLEDGE AND FREQUENCY OF CONSUMPTION OF EXTRUDED PRODUCTS IN THE STUDENT POPULATION
No full textEkstrudati su proizvodi dobiveni procesom ekstruzije koji omogućava obradu raznih vrsta sirovina i na kraju dobivanje gotovog proizvoda u što kraćem vremenskom periodu. U procesu ekstruzije ponajviše se koriste sirovine bogate proteinima i škrobom, a jedna od popularnijih sirovina je kukuruzna krupica. Kako se razlikuju od ostalih proizvoda na prvi pogled se ne može prepoznati od kojih sirovina potječu zbog svoje izmijenjene strukture (npr. corn flakes). Cilj ovoga završnoga rada je praćenje učestalosti konzumacije ekstrudiranih proizvoda među studentima. U anketnom upitniku sudjelovalo je 56 ispitanika različite dobi, spola, godine studija, mjestu stanovanja tijekom studija, prehrambene navike tijekom studija, poznavanje ekstruzije i ekstrudiranih proizvoda te učestalost konzumacije istih. Istraživanje je pokazalo da ispitanici ekstrudirane proizvode uvrštene u anketni upitnik najčešće konzumiraju jedanput ili tri puta na tjedan ili ih ne konzumiraju dok svaki dan ili pet puta na tjedan ih rijetko konzumiraju.Extrusion is a process in which extruded products are made out of all kinds of raw material in the shortest possible time. In this process, most raw materials are rich in protein and starch. The most used item for extrusion is corn grits. Extrudites cannot be easily guessed from which raw material they made because of their changed structure (for example corn flakes). The main agenda of this paper is to take a closer look into the consumption of extruded products. The focus was on students. In the survey 56 students of different ages, sex, background, and extrusion knowledge were asked about this process. The research showed that the respondents extruded products included in the survey questionnaires most often consume once or three times a week or not consume while they rarely consume them every day or five times a week
Critical assessment of quality assurance system at higher education institutions from facultyY PERSPECTIVE – EVIDENCE FROM CROATIA
No full textAs a signatory of the Bologna Declaration the Republic of Croatia has committed itself to implement a system of quality assurance (QA) for higher education, following the Standards and Guidelines for Quality Assurance in the European Higher Education Area. The implementation process has started in 2009 with the Act on Quality Assurance in Science and Higher Education (Official Gazette 45/09). The main goal was to improve the quality in higher education, respectively learning and teaching process. This paper aims to explore the perception of Croatian faculty on whether the introduction of QA system at Croatian higher education institutions (HEIs) has led to the improvement of quality in their teaching. The research was conducted using an online questionnaire in 2020, on a sample of 382 faculty members at public HEIs throughout Croatia (with 95 % of confidence level and 2, 16 confidence interval). The results indicate that despite all the efforts and introduced QA system in all surveyed institutions, only a small part of surveyed faculty members, about one-third, see a positive link between the implemented QA system and raising the quality of their teaching process

CHEMICAL COMPOSITION AND INFLUENCE OF COFFEE ON HUMAN HEALTH
No full textCilj završnog rada bio je odrediti kemijski značajne spojeve koji se nalaze u kavi te utjecaj spomenutih spojeva na zdravlje ljudi. Istraživanjem je potvrđeno da kava posjeduje niz biološki važnih spojeva koji doprinose zdravlju ljudi te djeluju preventivno na razvoj različitih bolesti poput kardiovaskularnih, neurodegenerativnih, bolesti jetre itd. U svrhu istraživanja provedena je anketa s ciljem utvrđivanja navike ispijanja kave među studentskom populacijom kako bi se dobila što realnija slika o tome pije li se kava samo iz navike ili zbog svojih pozitivnih učinaka na organizam. Anketom je utvrđeno da se kava pije samo iz navike i zbog dobrog okusa te da studenti ipak nisu dovoljno informirani o mogućim dobrobitima ovog napitka.The aim of the final work was to determine the chemically significant compounds found in coffee and impact of these compounds on human health. Research has confirmed that coffee has a number of biologically important compounds that contribute to human health and have a preventive effect on the development of various diseases such as cardiovascular, neurodegenerative, liver disease, etc. For the purpose of the research, a survey was conducted with the aim of determining the habit of drinking coffee among the student population in order to get a more realistic picture of whether coffee is drunk only out of habit or because of its positive effects on the body. The survey found that coffee is drunk only out of habit and because of its good taste and that students are still not sufficiently informed about the possible benefits of this beverage
