Utjecaj uvođenja biljnih ulja i mikroalgi u hranu kokoši nesilica na profil masnih kiselina u žumanjku jajeta i zdravstvene lipidne indekse
No full textTable eggs are a good source of nutrients. The nutritional properties of eggs are influenced by the composition of laying hens’ feed mixtures. An important compo-nent in the feed mixtures are the oils, which, in addition to their energy value, are also important for the absorption of liposoluble vitamins. Oils differ in the content of fatty acids, which play a significant role in metabolism and health maintenance. The lipid indices, such as the atherogenic (AI), thrombogenic (TI), and hypo/hypercho-lesterolemic fatty-acid ratio index (HH), are used when evaluating the lipid-quality indicators in eggs. This study aimed to produce the eggs enriched with the n-3 PUFA and to determine which feeding treatment yields the eggs with the most favorable lipid quality. The three groups of layers (treatments A, B, and C) were used in the experiment, which were fed with the mixtures of a modified composition considering the oils and microalgae used. The mixtures were balanced at the level of 17% crude protein and 12.10 MJ/kg ME. The produced eggs were used for an analysis of fatty-acid content (SFA, MUFA, n-6 PUFA, and n-3 PUFA), on the basis of which the lipid indices were calculated. The research results of eggs from the A, B, and C feeding treatments showed that the AIs were 0.485, 0.476, and 0.453; the TIs were 0.802, 0.681, and 0.653, and the HH indices amounted to 2.976, 2.983, and 3.068. The activi-ties of the Λ5- and Λ6 desaturases in the synthesis of the n-6 PUFA and the n-3 PUFA in eggs differed between the feeding treatments. The influence of a composition of feed mixtures in the laying hens’ diet on the quality of lipid indices was determined, and the eggs from the treatment C had the most favorable health-lipid indices.Konzumna jaja dobar su izvor hranjivih tvari. Na hranjiva svojstva jaja utječe sastav krmne smjese za kokoši nesilice. Važna komponenta u krmnim smjesama su ulja, koja su osim energetske vrijednosti važna i za apsorpciju vitamina topljivih u mastima. Ulja se razlikuju po sadržaju masnih kiselina, koje imaju značajnu ulogu u metabolizmu i očuvanju zdravlja. Lipidni indeksi, kao što su aterogeni (AI), trombogeni (TI) i indeks omjera hipo-hiperkolesterolemičnih masnih kiselina (HH), koriste se pri procjeni pokazatelja kvalitete lipida u jajima. Ovo istraživanje imalo je za cilj proizvesti jaja obogaćena n-3 PUFA-om, te utvrditi iz kojega hranidbenog tretmana jaja imaju najpovoljniju kvalitetu lipida. U pokusu su korištene tri skupine nesilica (tretmani A, B i C) koje su hranjene smjesama modificiranoga sastava s obzirom na korištena ulja i mikroalge. Smjese su bile uravnotežene na razini 17 % sirovih proteina i 12,10 MJ/kg ME. Proizvedena jaja korištena su za analizu sadržaja masnih kiselina (SFA, MUFA, n-6 PUFA i n-3 PUFA), na temelju čega su izračunati lipidni indeksi. Rezultati istraživanja jaja iz hranidbenih tretmana A, B i C pokazali su da su AI 0,485, 0,476 i 0,453; TI su 0,802, 0,681 i 0,653, a HH indeksi 2,976, 2,983 i 3,068. Aktivnosti Λ5- i Λ6 desaturaza u sintezi n-6 PUFA i n-3 PUFA u jajima razlikovale su se između hranidbenih tretmana. Utvrđen je utjecaj sastava krmnih smjesa u hranidbi kokoši nesilica na kvalitetu lipidnih indeksa, a najpovoljnije zdravstvene lipidne indekse imala su jaja tretmana C
Storytelling: Qualitative analysis of the influence on gen Alpha’s consumption decisions and affective buying behaviours in a developing market
No full textThe study employed a qualitative approach to determine the influence and effectiveness of storytelling in shaping the Alpha generation’s buying decisions and consumption behaviours. The students of the University of Lagos Junior Secondary School were selected for the study. The interview questions were set to focus on factors like experiences, sources of storytelling communication, the outcomes and the affective effects. Twenty-five students were purposively selected out of one hundred and twelve (112) population for the interview based on the conditions for selection. Thematic analysis was used and a total of 244 themes were identified. Four (4) major themes were later identified in thematic synthesis through coding translation. The findings revealed that storytelling is effective and strategic in brands targeted at the Alpha generation, hence, the generation relied on storytelling to choose brands in convenience, impulsive and shopping products, and radio and television were the main sources of storytelling campaigns among the generation. Storytelling wrapped in songs, entertainment, dancing, drama, etc. captivated and influenced the generation, and children used the information from the storytelling campaigns to influence family purchase decisions and parents’ buying decisions and behaviours
The Right of the Child in the European Context
No full textDjeca su naše najveće blago – fraza je koja se koristi već desetljećima i koja znači da bez djece naš život ne bi bio potpun. No, u prošlosti djeca čim bi stala na noge već bi se smatrali odraslima te bi morali raditi i pridonositi domaćinstvu. Dječja prava bila su zanemarena do te mjere da djeca niti su išla u školu niti su bila na neki način integrirana u društvo, već bi samo služila kao resurs roditeljima za zaradu. Mnogi očevi prodavali su svoju djecu, kako bi prehranili ostatak obitelji, jer su se ta djeca smatrala viškom. Samo je mali dio djece bio u mogućnosti školovati se i proživjeti svoje djetinjstvo onako kako ga djeca trebaju proživjeti – igrajući se. Tek se 1989. usvajanjem Konvencije o pravima djeteta, svijet ujedinio s ciljem da se stvori svijet kakav djeca zaslužuju. Tom Konvencijom propisana je zaštita djece, sve što svako dijete treba imati ili smije učiniti te na koji način se treba postupati prema djeci. Dječja prava svakom djetetu trebaju osigurati mogućnost da dosegne najviše što može. Sva su prava povezana i jednako važna. Osim što nam prava pripadaju jer smo se s njima rodili, jednako je važno da poštujemo i tuđa prava. Stoga, cilj ovog rada jest na pravilan način prikazati prava djece te kojim su dokumentima prava djeca zaštićena. Nadalje, prikazat će se problemi s kojima se djeca susreću pri ostvarivanju svojih prava. Zatim, u radu je prikazana sudska praksa kojom se prikazuje da kada je u pitanju dijete, slučaj treba riješiti u najboljem interesu djeteta
The Philosophy of Dialogue and Relationship in Martin Buber's "I and Thou"
No full textMartin Buber smatra se jednim od začetnikom filozofije dijaloga, a elemente ove filozofske grane on predstavlja u svom djelu Ja i Ti. Njegova filozofija dijaloga temelji se na odnošajnom principu ljudske egzistencije, stoga se njegova filozofija dijaloga može shvatiti i kao filozofija odnosa. Čovjek je definiran kao biće koje je u neprestanom odnosu, a u mogućnosti je ostvariti dvije temeljne vrste odnosa, koje su predstavljene putem parova riječi. Ti osnovni parovi riječi su Ja-Ono i Ja-Ti. Odnos Ja-Ono predstavlja ljudsko ophođenje prema drugom čovjeku, svijetu i Bogu na način koji je obilježen objektivizacijom, iskorištavanjem te instrumentalizacijom. To je odnos koji prevladava u suvremenom dobu, a takav odnos omogućava empirijsku spoznaju, no ne dovodi do mogućnosti ostvarenja cjelovite vlastite egzistencije. Nasuprot tome je odnos Ja-Ti koji predstavlja istinsko i autentično bivanje s drugim, te je takva vrsta odnosa čovjekovo najizvornije i najvrijednije obilježje. Stupiti u Ja-Ti odnos znači biti uistinu prisutan pred drugim, te djelovati neposredno. Taj odnos moguće je ostvariti u sferi Između koja je dinamičan prostor u kojemu se odnos zbiva, a njegova je najvažnija odlika uzajamnost u djelovanju dvaju bića. Odnos Ja-Ti, te Buberova filozofija dijaloga nije ograničena samo na kategoriju ljudskoga, nego je u njoj prisutan i odnos s svijetom, prirodom i Bogom. Pri oblikovanju svoje filozofske misli, Buber je ponajviše bio potaknut židovskim mističkim pokretom-hasidizmom, stoga je odnos Ja-Ti predstavljen i kao način pronalaženja i prilaženja Bogu. Usvajanje i ostvarivanje odnosa Ja-Ti dovodi do duhovnog razvoja pojedinca, do razvitka suosjećanja, te naposljetku i do pronalaženja smisla vlastitog života
Analysis of Changes in the Capital Structure of Companies : Graduate paper
No full textStruktura kapitala predstavlja iznimno bitan čimbenik upravljanja financijama tvrtki te se stoga i njome bave različite teorije. U radu su opisane poznate teorije strukture kapitala, među kojima su Modigliani-Millerova teorija, teorija kompromisa (engl. trade-off theory), teorija hijerarhije financijskih izbora (engl. pecking order theory) te teorija tempiranja tržišta (engl. market timing theory). Istraživački dio rada nastoji pružiti odgovor na pitanje povezanosti kamatnih stopa i strukture kapitala, odnosno, je li promjena strukture kapitala tvrtki povezana s promjenom kamatnih stopa na tržištu. U tu svrhu provedena je regresijska analiza korištenjem modela fiksnih efekata. Kao zavisne varijable predstavljena su tri modela - ukupne obveze/ukupna imovina, ukupni dug/ukupna imovina te dugoročni dug/ukupna imovina. Period promatranja obuhvaća razdoblje od 2016. do 2023. godine na uzorku od 2.677 američkih tvrtki. Navedeni uzorak tvrtki je uključivao nefinancijske tvrtke s minimalnom vrijednošću ukupne imovine u vrijednosti najmanje milijun dolara. Testirana je povezanost različitih varijabli s postavljenim modelima i to: Modela 1 (ukupne obveze/ukupna imovina), Modela 2 (ukupni dug/ukupna imovina) i Modela 3 (dugoročni dug/ukupna imovina), a odabranih na osnovu provedenog istraživanja radova drugih autora. Dobiveni rezultati ukazali su na statistički značajnu i pozitivnu povezanost varijabli „kamatna stopa“, „profitabilnost“ i „visina materijalne imovine“ na Model 1. Jednako tako statistički značajnu, ali negativnu povezanost imale su varijable „veličina imovine“, „performansa“, „likvidnost“ i „mogućnost za rast“. Ista povezanost varijabli materijalna imovina“, „performansa“, „likvidnost“ i „mogućnost za rast“, bila je za Model 2. Jedino je nezavisna varijabla „veličina imovine“ imala pozitivnu povezanost. Za Model 3, statistički značajna varijabla s pozitivnom povezanošću bila je „materijalna imovina“, dok su negativnu povezanost imale varijable „performansa“, „likvidnost“ te „mogućnost za rast“. Varijable „profitabilnosti“ i „kamatne stope“ nisu imale statistički značajnu povezanost sa zadnja dva modela.The capital structure represents an extremely important factor in the management of company finances, and therefore different theories deal with it. The paper describes well-known theories of capital structure, including Modigliani-Miller theory, trade-off theory, pecking order theory and market timing theory. In the Research part of the work, the question of the connection between interest rates and capital structure is dealt with, that is, whether the change in the capital structure of companies is related to the change in interest rates on the market. For this purpose, a regression analysis was performed using the fixed effects model. Three models are presented as dependent variables - total liabilities/total assets, total debt/total assets and long-term debt/total assets. The observation period was from 2016 to 2023 on a sample of 2,677 American companies. The stated sample of companies included non-financial companies with a minimum total asset value of at least one million dollars. The connection of various variables with the set models was tested, namely: Model 1 (total liabilities/total assets), Model 2 (total debt/total assets) and Model 3 (longterm debt/total assets), which were selected based on the conducted research of the works of other authors. The obtained results indicated a statistically significant and positive connection between the variables of interest rate, profitability and tangible assets on Model 1. The variables of asset size, performance, liquidity and growth had an equally statistically significant but negative connection. The same connection for variables - tangible assets, performance, liquidity and growth, was for Model 2. Only the independent variable asset size had a positive relation. For Model 3, the statistically significant variable with a positive correlation was tangible assets, while the variables of performance, liquidity and the growth had a negative correlation. The variables of profitability and interest rate did not have a statistically significant relationship with the last two models
Overview of Gamified and Game-based Vocabulary Learning in Esp
No full textThis paper explores the efficacy of gamified vocabulary learning and game-based learning in the context of English for Specific Purposes classes in higher education. It investigates how these innovative approaches can enhance vocabulary acquisition and student engagement compared to traditional learning approaches. The study evaluates students’ perceptions of gamification and game-based learning as positive, highlighting their competitiveness and motivational effects. While incorporating games into English for Specific Purposes classes resulted in significant post-test improvements in vocabulary, challenges such as reliance on digital tools, poor internet connectivity and lack of teacher digital literacy were identified. The paper also discusses the drawbacks of gamification and game-based learning, such as their potential negative impact on spelling and handwriting skills. Recommendations for future research include larger-scale studies encompassing diverse student populations and exploring the long-term effects of gamification and game-based learning on language proficiency and real-life vocabulary application. The findings contribute to the understanding of the role of gamification and game-based learning in language acquisition and suggest that, despite some challenges, these approaches are effective in overcoming vocabulary learning barriers in higher education
The opinion of the general population about euthanasia
No full textCilj istraživanja: Ispitati mišljenje opće populacije o eutanaziji.
Nacrt studije: Presječno istraživanje.
Ispitanici i metode: U istraživanju su sudjelovali opći ispitanici. Dobrovoljno je sudjelovalo 100 ispitanika, od čega je bilo 73 osoba ženskog, a 27 osoba muškog spola, a dob ispitanika bila je rasprostranjena od 18 do 76 godina. Pri istraživanju korišten je papirnati upitnik u vlasništvu prof.dr.sc. Ane Borovečki, dr.med. za koji je tražena i dobivena dozvola za korištenje. Za većinu anketnih pitanja od ispitanika se tražilo da brojem od 1 do 5 izrazi svoje slaganje s ispitnom tvrdnjom, što je vrednovano prema Likertovoj skali od 1 do 5.
Rezultati: Postoji statistički značajan utjecaj stupnja obrazovanja na mišljenje o smislu života. Postoji statistički značajan utjecaj spola na mišljenje o medicinski potpomognutoj smrti. Ne postoji statistički značajan utjecaj dobi na mišljenje o prestanku i produljenju života umiruće osobe.
Zaključak: Sedamdeset dva posto ispitanika složilo se, ili u potpunosti složilo s tvrdnjom da umirući bolesnik sam ima pravo odlučiti o kraju svojega života, a s druge strane šezdeset šest posto ispitanika ne smatra da bi liječnicima trebalo biti zakonom dopušteno pomoći pacijentu koji boluje od neizlječive bolesti i živi u teškim bolovima da okonča vlastiti život, ako sam pacijent to zatraži.Research aim: To examine the opinion of the general population on euthanasia.
Study design: Cross-sectional research.
Subjects and methods: General respondents took part in the research. 100 respondents volunteered, of which 73 were female and 27 male, and age ranged from 18 to 76 years. A paper questionnaire owned by Prof. Ana Borovečki, PhD was used in the research for which a license for use was sought and obtained. For most of the survey questions, respondents were asked to express their agreement with the test claim by number 1 to 5, which was evaluated according to the Likert scale 1 to 5.
Results: There is a statistically significant impact of education on the opinion about the meaning of life. There is a statistically significant impact of gender on the opinion about physician-assisted suicide. There is no statistically significant impact of age on the opinion about the termination and extension of a dying person's life.
Conclusion: Seventy-two percent of respondents agreed, or fully agreed, that a dying patient alone has the right to decide on the end of their life, on the other hand, sixty-six percent of respondents do not think that doctors should be allowed by law to help a patient who suffers from incurable illness and lives in severe pain to end their own life if the patient so requests
Logistics forwarding operator in the procedure of importing goods from a third country as an outsourcing service : Graduate paper
No full textRad započinje prikazom metodologije prema kojoj je pisan, ista se proteže kroz sljedeća
poglavlja: predmet istraživanja, cilj istraživanja te znanstvene metode. Teorijski dio rada sadrži
definicije outsourcinga, špedicije te ostalih pojmova vezanih uz iste. Istaknute su prednosti
korištenja outsourcinga, isto kao i važnost kvalitetne poslovne analize prije odabira outsourcing
partnera. Špedicija je vrsta outsourcing usluge, a definira se kao skup poslova, operacija, pravila
i funkcija pomoću kojih se omogućuje otprema ili doprema robe iz matične u stranu državu i
obrnuto. Ključna osoba u špediciji je špediter koji organizira i kontrolira sve poslove vezane
uz proces špedicije. Najvažnije je da posjeduje potrebna znanja i certifikate kako bi usluga
špedicije mogla biti potpuna.
Praktični dio rada prati proces dostave robe iz Amerike do Hrvatske. Originalnim dokumentima
(na kojima su prekriveni točni podaci poduzeća zbog zaštite podataka) prikazan je kronološki
tijek nabave i uvoza robe iz Amerike u Hrvatsku.
Robu pratimo kroz cijeli proces transporta, procesom i dokumentacijski. Ponuda špeditera,
ugovor o zastupanju, dispozicija, račun robe, račun prijevoznika, potrebne dozvole za prijevoz,
pomorski teretni list, CMR, uvozna carinska deklaracija i konačni račun prikazani su na
stvarnom poslu uvoza robe. Detaljni pregled svakog od navedenih dokumenata daje uvid u to
koliko je zapravo proces uvoza robe iz zemlje koja nije članica Europske unije u zemlju članicu
jednostavan ukoliko odaberemo špeditera koji ima znanje, iskustvo i potrebne resurse.
Zaključak rada obuhvaća skup znanja iz teorije i prakse, objedinjuje bitne informacije te
prednosti i nedostatke brodskog prijevoza preko špedicije.The paper begins with a presentation of the methodology according to which it was written, it
extends through the following chapters: the subject of research, the goal of research and
scientific methods. The theoretical part of the paper contains definitions of outsourcing,
forwarding and other terms related to them. The advantages of using outsourcing were
highlighted, as well as the importance of quality business analysis before choosing an
outsourcing partner. Freight forwarding is a type of outsourcing service, and it is defined as a
set of jobs, operations, rules and functions that enable the shipment or delivery of goods from
the home country to a foreign country and reverse transport procedure. The important person in
forwarding is the forwarder who organizes and controls all tasks related to the forwarding
process. The most important thing is that he has the necessary knowledge and certificates so
that the forwarding service can be complete.
The practical part of the work follows the process of delivery of goods from America to Croatia.
The original documents (on which the exact data of the company are covered for data
protection) show the chronological flow of procurement and import of goods from America to
Croatia.
We monitor the goods throughout the entire transport process, process and documentation. The
freight forwarder's offer, representation agreement, disposition, goods account, carrier's
account, required transport licenses, sea bill of lading, CMR, import customs declaration and
final invoice are shown on the actual business of importing the goods. A detailed overview of
each of the mentioned documents gives an insight into how easy the process of importing goods
from a country that is not a member of the European Union to a member country is if we choose
a forwarder who has the knowledge, experience and necessary resources.
The conclusion of the paper includes a set of knowledge from theory and practice, combines
essential information and the advantages and disadvantages of shipping via forwarding
Young people's addiction to TikTok
No full textU današnje vrijeme život bez interneta je nezamisliv, već od malih nogu djeca se služe tehnologijama jer su one postale sastavni dio obrazovanja od vrtića pa do doktorskog studija, te se komunikacija mladih uglavnom provodi putem društvenih mreža poput Instagrama, WhatsApp-a, Snapchat-a ili TikToka. TikTok je društvena mreža koja je u zadnje vrijeme iznimno popularna zbog svoje jednostavnosti korištenja te sadržaja koji se plasira. TikTok sadržaj ograničene je minutaže, u kojem se jako puno informacija dobije u kratkom vremenu što može biti i korisno ukoliko se radi o edukativnom sadržaju ili promoviranju vlastitog proizvoda, što nije uvijek slučaj. Baš zbog svog kratkog trajanja sadržaja ono vrlo lako može zaokupiti osobu i dovesti do pretjeranog korištenja odnosno ovisnosti, a zatim i do svakodnevnih problema poput zanemarivanja školskih obaveza te narušavanja mentalnog zdravlje mlade osobe, a na koncu može dovesti i do rizičnih ponašanja mladih i djece. Također postavke privatnosti i dobnog ograničenja TikTok aplikacije su upitne kvalitete što također može biti na štetu osobe koja se koristi aplikacijom. Kako do takvih posljedica korištenja društvenih mreža nebi došlo potrebno je uvesti preventivne programe u obrazovnom sustavu, ali i u svome vlastitom obiteljskom domu. Mlade osobe potrebno je upozoriti na opasnosti koje se mogu nalaziti na društvenim mrežama te koje štetnosti može nanijeti neodgovorno korištenje istih.Nowadays, life without the Internet is unimaginable, from an early age children use technologies because they have become an integral part of education from kindergarten to doctoral studies, and young people's communication is mainly carried out through social networks such as Instagram, WhatsApp, Snapchat or TikTok. TikTok is a social network that has recently become extremely popular due to its ease of use and the content that is posted. TikTok content is of limited duration, in which a lot of information is obtained in a short time, which can be useful if it is about educational content or promoting one's own product, which is not always the case. Precisely because of its short duration of content, it can easily occupy a person and lead to excessive use or addiction, and then to everyday problems such as neglecting school duties and impairing the mental health of a young person, and in the end it can also lead to risky behavior in young people and children. Also, the privacy and age restriction settings of the TikTok application are of questionable quality, which can also be detrimental to the person using the application. In order to prevent such consequences from the use of social networks, it is necessary to introduce preventive programs in the educational system, but also in your own family home. Young people need to be warned about the dangers that can be found on social networks and the harm that can be caused by their irresponsible use
Breeding and selection of big game
No full textLovno gospodarenje predstavlja sustavno provođenje uzgojnih mjera u lovištu pri čemu nastojimo dovesti populaciju na optimalan broj čija će brojnost biti sukladna kapacitetu staništa. Tehničkim uređenjem lovišta poboljšavamo opću prikladnost lovišta. Jedna od glavnih uzgojnih mjera, odnosno zahvata koje primjenjujemo na populaciji krupne divljači je uzgojni odstrjel. Njegovim provođenjem izlučujemo pojedine jedinke koje svojim karakteristikama ne udovoljavaju zadanim kriterijima. Uzgojnom odstrjelu prethodi postavljanje selekcijskog indeksa, i njime određujemo parametre prema kojima ćemo provoditi selekciju divljači. Svaku bolesnu i ozlijeđenu jedinku izlučujemo sanitarnim odstrjelom tijekom cijele godine, a divljač koja je dostigla svoju gospodarsku zrelost, u sklopu obavljanja redovnog odstrjela pravodobno izlučujemo iz lovišta.Wildlife management represents systematic implementation of breeding measures in the hunting grounds, by which we strive to bring the population to an optimal number, which abundance will be in accordance with the capacity of the habitat. By technically arranging of the hunting ground, we improve its general suitability in places where the habitat does not require it. One of the main breeding measures, i.e. procedures that we apply to the large game population, is management hunt. By his conduction, according to age categories, we select individuals whose external appearance characteristics do not meet the given criteria. The management hunt is preceded by the setting of the selection index, and with it we determine the parameters according to which we will implement the selection of game according to age categories. Every sick and injured animal is removed by sanitary hunt throughout the year, and game that has reached its economic maturity is removed from the hunting ground in a timely manner as part of the regular hunt
