The European Corn Borer, Ostrinia nubilalis (Hubner), as a Vector of Aflatoxigenic and Ochratoxigenic Fungi
No full textKukuruzni moljac (Ostrinia nubilalis, Hubner, 1796.) je uz kukuruznu zlaticu (Diabrotica virgifera virgifera, LeConte, 1868.) gospodarski najznačajniji štetnik kukuruza. Gusjenica kukuruznog moljca izgriza list, buši stabljiku i smanjuje joj čvrstoću. Osim navedenih direktnih šteta od gusjenica, indirektne čine i odrasle jedinke prenoseći spore mikotoksigenih gljivica. Mikotoksini su sekundarni metaboliti koje gljivice sintetiziraju tijekom rasta na određenim supstratima. Oni, mogu biti uzročnici različitih bolesti kod ljudi i životinja najčešće putem hrane. Najistaknutiji mikotoksini su aflatoksin B1 i okratoksin A. Istraživanje je provedeno u cilju utvrđivanja potencijala leptira kukuruznog moljca da prenosi spore mikotoksigenih gljivica. Tijekom dvije vegetacije 2021. i 2022. u pokusnom polju Instituta u Osijeku, lovnom lampom u kukuruzištu su uhvaćeni leptiri. U laboratoriju su isprani s 1ml destilirane vode. Uzorak isprane vode za svaku jedinku leptira je nanesen na hranjivu podlogu. Nakon inkubacije razvijene kulture gljivica su podvrgnute morfološkoj determinaciji prema dostupnim ključevima. Tijekom istraživanja determinirani su rodovi Aspergillus spp., Penicillium spp., Trichoderma spp. i Fusarium spp. Uzorci čistih kultura nakon presađivanja dokazano pozitivni na aflatoksin B1 i okratoksin A determinirani su do rodova: Aspergillus spp. i Penicillium spp. U istraživanju je dokazano je da je kukuruzni moljac prijenosnik spora mikotoksigenih gljivica.The european corn borer (Ostrinia nubilalis Hubner, 1796.) (ECB) is with western corn rootworm (Diabrotica virgifera virgifera, Leconte, 1868.) (WCR) economicly the most significant corn pest. The ECB catapillar cause bites off leaves, drills through stem and weakens its firmness. Other than the mentioned primary damages, indirectly the adult individuals cause damage by carring the spores of mycotoxigenetic fungi. Mycotoxins are secundary metabolits which fungi synthesize during growth on specific substrate. They, can be the cause of different diseases on people and animals mostly by food. The most significant mycotoxings are aflatoxin B1 and ochratoxin A. The research has been done in the purpose of determening the ECB butterfly potential of carring the spores of mycotoxigenetic fungi. During two growing seasons, 2021. and 2022. in the experimental field of Institute of Osijek the butterflys were caught in corn fields with light traps. In laboratory they were rinsed with 1ml destilled water. The sample of rinsed water from every individual were inflicted on nutritious base. After incubation the developed fungi were submitted to morphological determination according to available keys. During research the following genus were determened: Aspergillus spp., Penicillium spp., Trichoderma spp. and Fusarium spp. The samples of pure cultures, after the determination, were proven to be positive on aflatoxin B1 and ochratoxin A. The positive samples belonged to the genus Aspergillus spp. and Penicillium spp. Transplanting the fungi of mentioned genus on nutritios base MEA (Malt extract agar), their extraction and finally by liquid chromatography, it is proven that the ECB is a carrier of mycotoxigenetic fungi
Assessment of gross and fine motor skills of primary education students
No full textSuvremen način života sa sobom nosi mnoge negativne posljedice i učinke, što se svakako odražava na djecu i njihov razvoj. Prevladava sjedilački način života među odraslima, ali i među djecom i mladima. Djeca sve manje vremena provode u igri na otvorenom kroz koju se upravo razvija motorika djeteta, kako gruba tako i fina. Osim toga, puno vremena i u školama provedu u sjedećem položaju. Nažalost, predmet tjelesne i zdravstvene kulture koji je nekoj djeci jedini organizirani način tjelovježbe često bude zanemaren i zapostavljen zbog nedostatka vremena za obradom nekog gradiva iz drugih predmeta. Vrlo je važno da su djeca tjelesno aktivna, da sudjeluju u raznim sportskim i tjelesnim aktivnostima. Tako se razvija njihova motorika, odnosno sposobnost korištenja vlastitog tijela. Razvijenost motorike utječe i na razinu razvijenosti motoričkih sposobnosti. Cilj ovog rada je procijeniti grubu i finu motoriku učenika starosti od 9 do 11 godina s obzirom na dob i spol. U istraživanju je sudjelovalo ukupno 83 učenika, od toga 43 učenika trećeg razreda i 40 učenika četvrtog razreda zadarskih osnovnih škola. Za procjenu grube motorike primijenjena je standardizirana baterija testova motoričkih sposobnosti za učenike primarnog obrazovanja, a za procjenu fine motorike učenici su nizali perlice na konopčić u određenom vremenu. Rezultati istraživanja ukazuju na statistički značajnu razliku među rezultatima za procjenu grube motorike s obzirom na dob, učenici četvrtog razreda postižu bolje rezultate. Rezultati za procjenu grube motorike s obzirom na spol gotovo pa se i ne razlikuju, jedino su rezultati fleksibilnosti statistički značajni što je bilo i za očekivati. Rezultati testa za finu motoriku statistički su značajni s obzirom na spol i na dob. Učenice postižu bolje rezultate u testu fine motorike. Sveukupno, gruba i fina motorika ispitanika prosječno je razvijena i sukladna njihovoj dobi.The modern way of life brings with it many negative consequences and effects, which certainly affects on children and their development. A sedentary lifestyle prevails among adults, but also among children and young people. Children are spending less and less time in outdoor play, through which the child's motor skills, both gross and fine, are being developed. In addition, they spend a lot of time in schools in a sitting position. Unfortunately, the subject of physical and health education, which is the only organized form of exercise for some children, is often neglected and neglected due to the lack of time to study some material from other subjects. It is very important that children are physically active, that they participate in various sports and physical activities. In this way, their motor skills develop, that is, the ability to use their own body. The development of motor skills also affects the level of development of motor skills. The goal of this work is to assess the gross and fine motor skills of students aged 9 to 11 years old considering to age and gender. A total of 83 students participated in the research, of which 43 third-grade students and 40 fourth-grade students from Zadar's elementary schools. To assess gross motor skills was used a standardized battery of motor skills tests for primary school students and for assess fine motor skills, students strung beads on a string in a certain time. The results of the research indicate a statistically significant difference between the results for the assessment of gross motor skills considering to age, fourth grade students achieve better results. The results for the assessment of gross motor skills considering to gender are almost same, there's no differents but only the results of flexibility are statistically significant, which is to be expected. The results of the test for fine motor skills are statistically significant considering to gender and age. Female students achieve better results in the test of fine motor skills. Overall, the subjects' gross and fine motor skills were averagely developed and appropriate for their age
Characteristics of cardiac activity during decision-making in morally questionable situations with different decision consequences
No full textDosadašnja istraživanja bila su uglavnom usmjerena na usporedbu deontoloških i utilitarnih odluka u moralnim dilemama te njihovih fizioloških promjena. Općenito govoreći, rezultati tih istraživanja uglavnom potvrđuju da se razina fizioloških varijabli, odnosno varijabilitet srčanih R-R intevala, kod moralnog rasuđivanja i odlučivanja mijenja ovisno o težini dileme i razini uključenosti aktera u istu, a dobivene razlike se prvenstveno pripisuju dominaciji kognitivne ili emocionalne komponente. Slijedom toga, cilj ovog istraživanja bio je ispitati promjene u srčanoj aktivnosti i nekim aspektima odluke u situacijama moralnog odlučivanja koje su se razlikovale s obzirom na težinu posljedica za prekršitelja i stupanj odgovornosti za procjenitelje/sudionike (uz/bez prisutnost drugih svjedoka). U istraživanju su sudjelovala 33 studenta sa Sveučilišta u Zadru, a eksperiment je uključivao prezentaciju dvaju, po slučaju rotiranih, hipotetskih scenarija o kršenju akademskih etičkih načela (s različitim težinama posljedica za aktera). Zadatak sudionika bio je, nakon što pročitaju scenarij, odgovoriti bi li prijavili prekršitelja i procijeniti sigurnost u odluku, ukoliko su bili jedini svjedok, te ako je bilo i drugih svjedoka. Tijekom cijelog ispitivanja sudionicima je registrirana dužina R-R intervala, kao i za vrijeme mirovanja koje je prethodilo svakoj eksperimentalnoj situaciji. Analizom rezultata utvrđeno je da sudionici češće prijavljuju prijatelja/kolegu kada su posljedice za njega lakše i kada ne mogu prebaciti odgovornost na nekog drugog (bez prisutnih drugih svjedoka) nego u ostalim situacijama. Nisu zabilježene razlike u sigurnosti u odluku, a vrijeme odluke je značajno duže samo kad su posljedice za prekršitelja blaže, a prekršaju su svjedočile i druge osobe. Sporije odlučivanje čini se posljedicom predomišljanja onih sudionika koji su odlučili prijaviti prekršaj. Iako je došlo do smanjenja parametara srčanog varijabiliteta u situacijama čitanja scenarija i tijekom donošenja odluka u odnosu na period mirovanja, nisu utvrđene razlike u vrijednostima bilježenih parametara srčane aktivnosti (MRR, SdRR, RMSSD, LF, HF, LF/HF) s obzirom na težinu posljedica za prekršitelja.Previous research was mainly focused on comparing deontological and utilitarian decisions in moral dilemmas, and their physiological changes. Generally, the results of these studies confirm that the level of physiological variables, i.e. the variability of cardiac R-R intervals, in moral reasoning and decision-making changes depending on the difficulty of the dilemma and the level of the actor's involvement. The obtained differences are primarily attributed to the dominance of the cognitive or emotional component. Consequently, the aim of this study was to examine changes in heart activity and some aspects of the decision in moral decision-making situations that differed with regard to the severity of the consequences for the offender and the degree of responsibility for the assessors/participants (with/without the presence of other witnesses). 33 students from the University of Zadar participated in the research, and the experiment included the presentation of two, rotated-by-case, hypothetical scenarios that show the violation of academic ethical principles (with different severity of consequences for the actor). After reading the scenario, the task was to answer whether they would report the offender and assess the certainty of the decision if they were the only witness, and if there were other witnesses. During the entire test, the length of the R-R interval was recorded for the participants, as well as the rest time preceding each experimental situation. It was determined that participants report a friend/colleague more often when the consequences are less severe and they cannot shift the responsibility to someone else (without other witnesses present) than in other situations. No differences were recorded in the certainty of the decision. The decision time is significantly longer only when the consequences for the offender are less severe and the offense was witnessed by other people. Slower decision-making seems to be caused by the reconsideration of the decision in participants who decided to report the violation. Although there was a decrease in cardiac variability parameters in scenario reading situations and during decision-making compared to the rest period, no differences were found in the values of the recorded cardiac activity parameters (MRR, SdRR, RMSSD, LF, HF, LF/HF) with regard to consequence severity for the offender
The correlation between the ability of mental visualization and success in geometry
No full textOva studija opisuje karakteristike i ishode matematičke domene nazvane Oblik i prostor. Sposobnost misaone vizualizacije objekata poznata kao prostorna vizualizacija, istaknuti je i važan prediktor geometrijskog uspjeha. Prikazane su teorije o geometrijskim konceptima kao tri različita pristupa geometriji. Prostorno razmišljanje utemeljeno na strukturi koja se temelji na geometrijskim svojstvima priznato je kao valjano geometrijsko zaključivanje. Ovo istraživanje donosi korelaciju između sposobnosti misaone vizualizacije i uspjeha u geometriji i to među učenicima četvrtog razreda osnovne škole. Za prikupljanje podataka korištena su dva instrumenta utemeljena na zadatcima iz misaone vizualizacije i geometrijskog dijela sadržaja. Dobivena je niska pozitivna korelacija među ovim dvjema varijablama i ona iznosi 0,38. Prikazana je korelacija među određenim zadatcima s najvišim koeficijentom 0,34 i najnižim 0,29. Učenički odgovori pokazuju dobro snalaženje u oba tipa zadataka. Pokazano je da se većina učenika prema van Hieleovoj teoriji nalazi na razini Analize.This study describes the characteristics and outcomes of a mathematical domain called Shape and Space. The ability to mentally visualize objects, known as spatial visualization, is highlighted as an important predictor of geometric success. The theories of geometric concepts are presented as three different approaches to geometry. Spatial reasoning based on structure derived from geometric properties is recognized as valid geometric reasoning. This research establishes a correlation between the ability of mental visualization and success in geometry among fourth-grade students. Two instruments based on tasks involving mental visualization and geometric content were used to collect data. A low positive correlation of 0.38 was found between these two variables. Correlations ranging from 0.34 to 0.29 were observed among specific tasks, with the highest and lowest coefficients mentioned. Student responses demonstrate proficiency in both types of tasks. It is shown that according to the van Hiele theory, the majority of students are at the Analysis levlel
Illegitimate births on the peninsula Pelješac from the end of the 19th century to the present day
No full textU ovom diplomskom radu se govori o izvanbračnim rađanjima koja nisu dovoljno analizirana u Hrvatskoj. Poluotok Pelješac je bio naseljen u prapovijesnom vremenu. Tijekom godina razvio se bolje nego drugi dijelovi Dalmacije. Zahvaljujući višem stupnju razvoja za vrijeme Dubrovačke Republike, mnogi ljudi su migrirali na poluotok, ali danas je prisutna depopulacija. Na kretanje broja stanovnika su utjecali društveni i gospodarski čimbenici koji su bili pod utjecajem geografskog položaja poluotoka. Zahvaljujući geografskom položaju poluotok je pošteđen ratova i bitki, ali to u isto vrijeme nije pomoglo društvenom i gospodarskom razvoju. Pelješac je poznat po vinogradarstvu i ostalim poljoprivrednim granama, turizmu i pomorstvu. Sve navedeno je prisutno i danas, ali turizam prednjači. U prošlosti, ljudi su drugačije gledali na izvanbračnu djecu. Majke su ih napuštale odmah nakon rođenja te je društvo često zlostavljalo djecu. Dio djece je pozakonjen nakon nekog vremena ženidbom svojih roditelja. Ljudi su se tijekom godina promijenili i prihvatili ih. Danas je puno lakše biti izvanbračno dijete, pogotovo u razvijenijim državama gdje je broj izvanbračne djece izrazito porastao u zadnjih 20 godina. U Hrvatskoj je najveći udio izvanbračne djece u Međimurskoj županiji, a najmanji u Splitsko-dalmatinskoj županiji. Zbog malog broja stanovnika na poluotoku, nema puno rađanja, a s tim ni izvanbračnih rađanja. Naselja koja su se obradila pokazuju nizak broj izvanbračnih rađanja i dosta godina tijekom promatranog razdoblja nije ni bilo izvanbračnih rađanja. Od svih analiziranih naselja u radu, Orebić ima najveći udio izvanbračnih rađanja čemu je razlog drugačiji razvoj kroz povijest i otvoreniji pristup stanovnika.This master thesis deals with illegitimate births, which are not analyzed enough in Croatia. Peninsula Pelješac was inhabited in ancient times. Over the years, while it was a part of Republic of Ragusa, it developed a lot more than the other parts of Dalmatia. Because of that a lot of people migrated to the peninsula, but today depopulation is increasing. The inhabitants were under the influence of social and economic factors which were also under the influence of geographical position. The geographical position did spare the peninsula from many wars and battles but at the same time it did not help with the social and economic development of the peninsula. Pelješac is known for vineyards and other agricultural crops, tourism and seafaring. All of these are still present today, but tourism dominates. In the past, society looked differently at illegitimate children. Their mothers would abandon them after their birth and they were often bullied by society. One aspect was legalized after some time because of their parents wedding ceremony. Over the years, people changed and accepted them. Today is a lot easier to be an illegitimate child, especially in more developed countries where are the highest rates of illegitimate births. In Croatia the number of illegitimate births increased in the last 20 years. County that has the highest percentage of illegitimate births is Međimurje County, and the one with the lowest percentage is Split-Dalmatia County. Because of the small number of inhabitants on the peninsula, there are not many births nor illegitimate births. Cities that were analyzed showed a low number in illegitimate birth rate and for many years of the analyzed period there were not illegitimate births. Of all th analyzed cities in this thesis, Orebić is the one with the highest percentage of illegitimate births which is because of the different development and more open-minded society
Managing Ravni kotari as a tourist destination in a function of developing rural tourism
No full textSvrha ovog diplomskog rada bila je utvrditi resurse i kapacitete s kojima područje Ravnih kotara raspolaže te ustanoviti ograničenja i nedostatke s kojima se analizirano područje susreće s ciljem postavljanja prijedloga i smjernica koje bi omogućile daljnji razvoj Ravnih kotara kao ruralne turističke destinacije. Ravni kotari pripadaju ruralnom prostoru Hrvatske, stoga je koncept ruralnog turizma temeljito razrađen i objašnjen. U radu je najprije teorijski pobliže objašnjeno aktualno stanje Ravnih kotara; temeljna obilježja, prirodne atrakcije, smještajni kapaciteti i ekonomski učinci od razvoja ruralnog turizma. Nadalje, prikazana je analiza marketinških aktivnosti, predstavljen je LEADER program, objašnjena je potreba holističkog pristupa i IRQ model, ustanovljene su prednosti i nedostaci u upravljanju ruralnim turizmom te je utvrđena uloga i zadaća Turističkih zajednica Ravnih kotara i Turističke zajednice Zadarske županije. Dani su prijedlozi i natuknice o mogućnostima daljnjeg razvoja ruralnog turizma te su isti potkrijepljeni provedenim empirijskim istraživanjem. Provedene su dvije ankete za upravljanje ruralnim turizmom u Ravnim kotarima te su interpretirani rezultati na temelju kojih su se utvrdili zaključci o potencijalu i mogućnostima kvalitetnog razvoja ruralnog turizma na području Ravnih kotara. Prva se anketa bavila ispitivanjem stavova lokalnog stanovništva Zadarske županije o mogućnostima razvoja ruralnog turizma u Ravnim kotarima, a druga stavovima privatnih iznajmljivača Ravnih kotara o razvoju turizma u njima. Iz obaju anketa došlo se do zaključka kako su glavni problemi Ravnih kotara promocija i marketing područja, nedostatak turističke ponude, iseljavanje stanovništva te nedostatna suradnja s ostalim turističkim zajednicama. Isto tako, utvrđeno je kako Ravni kotari sadrže predispozicije za razvoj ruralnog turizma; poput predivne prirode i krajolika, bogate gastronomske tradicije i bogate kulturno-povijesne umjetnosti. No, potrebno je uložiti zajednički trud i energiju, uplesti državna tijela i ostala sredstva koja će moći omogućiti daljnje kreiranje turističke ponude ruralnog područja Ravnih kotara.The purpose of this graduate thesis was to determine the resources and capacities that the area of Ravni Kotari have and to establish the limitations and shortcomings that the analyzed area faces, with the aim of setting proposals and guidelines that would enable the further development of Ravni Kotari as a rural tourist destination. Ravni Kotari belong to the rural area of Croatia, therefore the concept of rural tourism has been thoroughly elaborated and explained. In the paper, the current state of Ravni Kotari is first theoretically explained in more detail; basic characteristics, natural attractions, accommodation capacities and economic effects from the development of rural tourism. Furthermore, the analysis of marketing activities are presented, the LEADER program is presented, the need for a holistic approach and the IRQ model is explained, the advantages and disadvantages of managing rural tourism are established, and the role and task of the Tourist Boards of Ravni Kotari and the Tourist Board of the City of Zadar are determined. Proposals and hints on the possibilities of further development of rural tourism were given and they were grounded by the conducted empirical research. Two surveys were conducted for the management of rural tourism in Ravni Kotari and the results were interpreted, based on which conclusions were drawn about the potential and possibilities of quality development of rural tourism in the area of Ravni Kotari. The first survey dealt with the examination of opinions of the local population of Zadar County on the possibilities of developing rural tourism in Ravni Kotari, and the second on the opinions of private renters of Ravni Kotari on the development of tourism. From both surveys, it was concluded that the main problems of Ravni Kotari are promotion and marketing of the area, lack of tourist offer, emigration of the population and insufficient cooperation with other tourist communities. Likewise, it was established that Ravni Kotari contains predispositions for the development of rural tourism; such as beautiful nature and landscape, rich gastronomic tradition and rich cultural and historical art. However, it is necessary to invest joint effort and energy, involve state bodies and other resources that will enable further creation of the tourist offer of the rural area of Ravni Kotari
Correlation in the teaching of music and physical culture
No full textMeđusobno povezivanje školskih predmeta donosi kreativnost, zanimljivost te se podiže učenikova zainteresiranost za nastavne satove. Glazba i pokret se međusobno povezuju od postanka svijeta. Otkako postoji zvuk postoji i pokret putem kojeg možemo izraziti sve svoje emocije, kako pozitivne tako i negativne. Diplomski rad istražuje koliko učitelji/ce povezuju glazbenu i tjelesnu i zdravstvenu kulturu, a dodatni cilj je poticanje djece na što više povezanosti glazbe i tjelesnog odgoja. U prvom dijelu rada prožimaju se teme povijesti postanka glazbe, od životinja do ljudi pa tako i tjelesne i zdravstvene kulture, odnosno pokreta koji se nadovezuje na postanak glazbe. U drugom dijelu rada provedena je ljestvica procjene povezanosti glazbene i tjelesne i zdravstvene kulture u nastavi gdje možemo vidjeti koliko i na koji način učitelji/ce zapravo provode korelaciju. Za dobivanje relevantnih rezultata istraživanja kao metoda istraživanja korištena je online anketa. Rezultati provedene ankete pokazuju da više od polovine anketiranih učitelja/ca u velikom broju nastavnih sati provode korelaciju u nastavi glazbene i tjelesne i zdravstvene kulture.Connecting school subjects to each other brings creativity and interest and the student's interest in the lessons is raised. Music and movement have been inter connected since the beginning of the world. Since the rehas been sound, there has also been movement through which we can express all ourer motions, both positive and negative. This master thesis examines how much teachers try to connect musical and physical culture, and the additional goal is to encourage children to connect to music and physical education as much as possible. In the first part of the paper, they are interwoven the mes of the history of the origin of music, from animals to people and also physical culture and movement which builds on the creation of music. In the second part of the paper, a connection as sessment scale was implemented music and physical education in classes where we can see what percentage of teachers actually do perform correlation. An online survey was used as a research method to obtain relevant research results. The results of the survey show that more than half of the surveyed teachers in a large number of teaching hours correlatein music and physical education classes
Motor readiness of children before starting school
No full textRazvoj motorike kod djeteta podrazumijeva uspješnost provedbe motoričkih aktivnosti. Stjecanje različitih načina kretanja neophodno je za cjeloviti razvoj djeteta i stjecanje motoričkih kompetencija. Ovaj diplomski rad usmjeren je na istraživanje usvajanja biotičkih motoričkih znanja uz pomoć kojih dijete upravlja svojim tijelom u prostoru. Cilj rada je utvrditi razinu kvalitete usavršenosti motoričkih vještina, kod djece starosne dobi od 5 do 7 godina koristeći testove procjene motoričkih znanja u dvije točke mjerenja. Metoda rada provodi se na temelju testova za mjerenje motoričkih postignuća, koristeći 4 domene od kojih svaka sadrži 3 vježbe što čini ukupno 12 vježbi: prvi test uključuje 3 vježbe iz domene svladavanja prostora, drugi test sastoji se od 3 vježbe iz domene svladavanja prepreka, treći test uključuje 3 vježbe iz domene svladavanja otpora i četvrti 3 vježbe u domeni svladavanja baratanja predmetima. Rezultati završnog mjerenja ukazuju na bolje rezultate nego u odnosu na početno mjerenje.The development of child’s motor skills implies the ability to perform motor activities. Performing different movements is a crucial part of child development and acquiring motor skills. In this research we focus on the development of biotic motor knowledge that helps a child perform certain movements in space. The aim of this study is to measure the motor skills performance level, in children ages 5 to 7, as they perform certain tasks measured through the motor skills development assessment, comparing the results in two measurement points. Our method focuses on measuring motor skills through motor skills assessment with 4 domains, each of which has 3 exercises with a total of 12 exercises: first test includes 3 exercises in mastering space domain, second test contains 3 exercises to master obstacles, third test includes 3 exercises to master resistance domain, and fourth test is comprised of 3 exercise to understand child’s ability to use objects. The final results show the improvement over the initial pre-assessment measurements
The importance of social capital for finding a job in the profession of social studies graduates at the University of Zadar
No full textDruštveni kapital kompleksno je područje proučavanja i istraživanja unutar sociologije prema tome i shvaćanje društvenog kapitala i njegove funkcije. Shvaćanje njegove funkcije odnosno koristi koju je moguće ostvariti preko njega, ovisi o kontekstu i perspektivi iz koje se promatra. Ovaj rad se usmjerio na istraživanje društvenog kapitala u obliku poznanstava i mreža koje su bivši studenti/ice stvorili tijekom studija te koristi koju su ostvarili stvorenim društvenim kapitalom po završetku studija. Proces pronalaska poslova nakon završenog studija s naglaskom da je posao unutar područja struke, zanimljiv je proces koji traži određene vještine. Istraživanje se temeljilo na kvalitativnoj metodologiji stoga se proučavao subjektivni doživljaj sugovornika o njihovom društvenom kapitalu te njihovo shvaćanje značaja mreža i poznanstava ostvarenih tijekom studija i unutar područja struke. Prikupljeni podaci istraživanja dobiveni provedbom 10 polu-strukturiranih intervjua sa sugovornicima diplomiranim studentima društvenih smjerova koji rade unutar područja završene struke, analizirali su se tematskom analizom. Tematskom analizom dobiveno je ukupno 5 tematskih kategorija unutar kojih su se razradili kodovi te interpretirali rezultati istraživanja. Zaključak analize rezultata istraživanja temelji se na pretpostavci o važnosti društvenog kapitala kao olakšavajućeg faktora koji pruža brojne koristi te omogućava prilike za razvoj sveukupnog kapitala kako individue tako i grupe u kojoj je individua umrežena.Social capital is a complex area of study and research within sociology, so is the understanding of social capital and its function. Understanding its function, or the benefit that can be achieved through it, depends on the context and perspective from which it is observed. This paper focused on the research of social capital in the form of acquaintances and networks that former students created during their studies and the benefit they achieved with the created social capital after completing their studies. The process of finding a job after completing your studies, emphasizing that the job is within the field of expertise, is an interesting process that requires certain skills. The research was based on qualitative methodology, therefore the interviewees' subjective experience of their social capital and their understanding of the importance of networks and acquaintances made during studies and within the field of profession were studied. Collected research data obtained by conducting 10 semi-structured interviews with interlocutors, graduate students of social studies who work within the field of the completed profession, were analyzed by thematic analysis. The thematic analysis resulted in a total of 5 thematic categories within which the codes were developed and the research results were interpreted. The conclusion of the analysis of the research results is based on the assumption of the importance of social capital as a facilitating factor that provides numerous benefits and provides opportunities for the development of the overall capital of both the individual and the group in which the individual is networked

Hidraulična pritezna vitla su vrlo čest odabir na brodovima zbog njihove robusnosti, mogućnosti regulacije i karakteristika. U ovom radu su prikazani i opisani dijelovi brodskog vitla te pojedinačni dijelovi hidrauličkog sistema. Kroz zadatak se uočava da je brzina vrtnje vitla uz silu pritezanja glavni faktor za određivanje potrebne snage te se osvrće na praktične izvedbe, tehnološka rješenja i zahtjeve vitla pri radu u brodarskoj industrijiMooring winches are an important part of a ship's fittings because they are used for mooring operations and securing the ship in port. Hydraulic mooring winches are often the choice on ships because of their rigidness and capabilities for regulation. In this work of study parts of mooring winches are shown and described along with the individual parts of the hydraulic system. Through the mathematical task it is observed that the speed of the winch beside force of tension is the main factor for finding the power of the hydraulic motor. Practical and tehnological solutions with requirements during operation in the ship industry were discussed
