Significance of long - Term Assets Accounting for the Business Result
No full textDugotrajna imovina temelj je poslovanja većine poduzeća, a posebice kada je riječ o poduzećima koja obavljaju proizvodne djelatnosti te imaju vrlo vrijednu imovinu. Dugotrajna imovina se uporabom postupno troši, zbog čega je njenu vrijednost potrebno postupno prebaciti na troškove proizvodnje, a kako bi se u konačnici prikazala realna vrijednost troškova proizvodnje po pojedinom proizvodu. Pravilan izračun i iskazivanje amortizacije je važno i zato jer se na takav način otklanjaju sumnje u moguću manipulaciju poslovnim rezultatom.
U ovom radu prikazane su sve bitne odrednice značaja računovodstva dugotrajne imovine za poslovni rezultat, a poseban naglasak stavljen je na utjecaj amortizacijskih stopa te metoda obračuna amortizacije na financijski rezultat. Amortizacija bi se mogla koristiti s ciljem prilagođavanja financijskog rezultata poduzeća (na više ili na niže vrijednosti) budući da je u slučaju pojedinih poduzeća amortizacija jedan od vedrih troškova. To se posebice ističe u slučaju poduzeća koja posjeduju vrlo vrijednu opremu te građevine. Kada je riječ o poduzeću koje je promatrano u ovom radu, otežano je kreiranje zaključaka o utjecaju amortizacije na financijske izvještaje te financijski rezultat poslovanja iz razloga što poduzeće u svojim financijskim izvještajima nije navelo koje amortizacijske stope su korištene za potrebe obračuna amortizacije.Long- term assets are essential for business operations of most companies, especially when it comes to companies that perform production activities and have very valuable assets. Long- term assets are gradually amortized by use, which is why it is necessary to gradually transfer their value to production costs per individual product. Proper calculation and presentation of amortization is also important because in this way doubts about possible manipulation of the business result are removed. This paper presents all the important determinants of the importance of the accounting of long-term assets for the business result, and special emphasis is placed on the impact of amortization rates and amortization calculation methods on the financial result. Amortization could be used with the aim of adjusting the company's financial result (to higher or lower values), since in the case of certain companies amortization is one of the major costs. That is especially noticeable in the case of companies that own very valuable equipment and buildings. When it comes to the company observed in this paper, it is difficult to make conclusions about the impact of amortization on the financial statements and the financial result of the business because the company did not specify in its financial statments which amortization rates were used for the purposes of calculating amortization
Analysis and perspectives of cruising tourism in Dubrovnik
No full textU ovom radu obrađen je pojam kruzing turizma kao jednog od najpopularnijih oblika putovanja danas. Današnji mega brodovi nazivaju se plutajućim hotelima jer zaista svojim uslugama nude gostima apsolutno sve od gastronomije, zabave, opuštanja i ostalih čimbenika koji su bitni prilikom odabira putovanja. Mediteran je danas jedna od najvećih kruzing regija. Uz Veneciju svakako treba spominjati i Dubrovnik koji je danas zasigurno među njegovim najvećim i najpopularnijim lukama. Sukladno tome u radu su obrađeni pozitivni i negativni utjecaji kruzing turizma na Dubrovnik kao destinaciju, mjere koje su poduzete da bi se negativni utjecaji suzbili i smanjili, te perspektive i ideje koje bi u budućnosti kruzing turizam u Dubrovniku podigle na novu razinu.The main topic of the final thesis is cruising tourism which is one of the fastest growing industries in the world. Cruise ships today are made as a big floating resorts since they are offering every kind of service for their guests. Mediterranean is today one of the most popular cruising regions in the world. Beside Venice Dubrovnik is for sure one of its most popular ports. In accordance with that cruise tourism for sure has a big positive and negative impacts on Dubrovnik as destination. Certain measures have already been taken to repress negative impacts but there is for sure more space to improve these impacts and bring cruise tourism in Dubrovnik on certain level
Media influence on self-alienation in postmodern society
No full textPostmoderno društvo i njegove karakteristike poput napretka tehnologije, a time razvoj medija izmijenio je potpuno strukturu društva, ljudskog djelovanja, razmišljanja i načina života. Svakodnevna izloženost informacijama i novim tehnologijama navodi nas da živimo u virtualnoj stvarnosti koja je neizbježna, gdje se brišu granice virtualnosti i realnosti. Upravo zbog društva kao takvog, umreženog, povezanog postavlja se pitanje jesmo li zaista sve povezaniji ili smo u potpunosti predani virtualnosti koja nam “stavlja zid“ i udaljava nas od prave komunikacije licem u lice, stvara nam distrakciju od pravih životnih situacija, sadašnjeg trenutka i time nas dovodi do otuđenja. Upravo to je i bit ovog rada, da istraži kako se manifestira otuđenje zbog medija u postmodernom društvu i u konačnici da, da odgovor, polustrukturiranim intervjuom.Postmodern society and its’ characteristics such as the advancement of technology, and thus the development of the media, have completely changed the structure of society, human action, thinking and lifestyle. Daily exposure to information and new technologies has leads us to a life in a virtual reality that has become inevitable, where the boundaries between virtual and reality are erased. Precisely because of this way of a networked, connected society, the question arises whether we are really becoming more connected or whether we are completely committed to the virtual, which separates and distances us from a real face-to-face communication, creates a distraction for us from real life situations, the present moment and thus makes us disconnect from ourselves and the environment. More precisely we become alienated. This is exactly the essence of this master thesis, to investigate how alienation is manifested due to media in postmodern society and ultimately to try to answer these questions.

"Pregnant women`s motivation to breastfeed"
No full textMajčino mlijeko prepoznato je kao najbolji izbor prehrane za zdrav rast i razvoj djeteta. Osim brojnih dobrobiti za dijete, ono ima pozitivne učinke i na zdravlje majke odmah iza poroda, a i u starijoj dobi. Svjetska zdravstvena organizacije i UNICEF se brojnim inicijativama zalažu kako bi se podigla svijest populacije i kako bi što veći broj žena odluĉilo dojiti. Cilj ovog završnog rada bio je anonimnim upitnikom procijeniti motivaciju za dojenje 100 trudnica Dubrovačko-neretvanske županije. Ispitano je znanje, prijašnja iskustva i mišljenje o dojenju. Rezultati pokazuju da su naše ispitanice dobro informirane o dojenju, komplikacijama koje se mogu javiti i načinu rješavanja istih. Međutim, veliki broj ispitanica smatra da je potrebna bolja edukacija trudnica i podrška medicinskog osoblja. Naime, glavni izvor informacija o dojenju u 42% trudnica su mediji, a za 31% njih majka i prijateljice. Motivacija žena za dojenje je, prema rezultatima, zadovoljavajuća. Oko 93% ispitanica planira dojiti dijete najmanje 6 mjeseci. Podrška za 85% ispitanica je obiteljsko okruženje, a za 68% njih najveći oslonac je životni partner.Breast milk is known to be the best choice when in comes to the growth and development of a child. Besides having numerous benefits on the child´s health, it contributes to the mother´s wellbeing and health as well. Not only immediatly after the birth but also later in life, when they are elderly. The World´s Health Organization (WHO) and the UNICEF support many initiatives in order to raise awarness among people and in order to incentivate more and more women to breast feed. The main goal of this final paper,is to estimate through an anonymous survey, the motivation of women from the Dubrovacko -Neretvanska county to breastfeed their child.
Previous experiences, knowledge, thougths and the motivation itself were examinated. It has resulted that women from this County are well informed about breastfeeding, the possible complications it brings and the methods there are to cure the later. However a reasonable number of them feels that a better education and support from the medical staff would be needed.
The results show that the main source of information for 42% are the media, wherheas for 31% it happends to be their mother or friend. As far as motivation goes, the questionnaire has shown that it is excellent. Approximately 93% of women plan to breastfeed their child for at least 6 months. For 85% of the respondents the family sorrounding brings sufficient support , moreover for 68% of pregnant women the greatest support is to be found in their partner

"Incidence of type 1 diabetes in childhood and adolescence"
No full textDijabetes tip 1 je kronični metabolički poremećaj koji dovodi do hiperglikemije. U djece, kao i u odraslih, energetski metabolizam je poremećen radi nedovoljne sekrecije inzulina ili zbog njegovog nedostatnog učinka, što utječe na metabolizam ugljikohidrata, masti i bjelančevina. Pojavljuje se u dječjoj dobi i u dobi adolescencije. Dosadašnji podaci svjetskih istraživanja pokazuju da u svijetu svake godine prosječno oboli oko 86,000 djece.
Cilj rada: je bio istražiti učestalost pojavnosti dijabetesa tip 1 u 10-godišnjem razdoblju na području Dubrovačko-neretvanske županije. Istraživanjem je utvrđeno u kojoj dječjoj dobi je najveći broj ustanovljene bolesti, postoji li razlika pojavnosti bolesti s obzirom na spol djeteta, te jeli kod oboljele djece bilo genetske predispozicije za pojavu bolesti. Istraživanjem je utvrđeno koliko se pacijenti drže zdravstvenih uputa, te koliko često odlaze na kontrole liječniku.
Ispitanici i metode: Ispitivanje je provedeno retrospektivnom analizom uvidom u povijesti bolesti pacijenata na Odjelu pedijatrije u OB Dubrovnik u 10-godišnjem razdoblju. Osim dostupnih brojčanih podataka iz povijesti bolesti konstruiran je upitnik prema zadanom cilju i proveden je među roditeljima oboljele djece.
Zaključak: Na globalnoj razini, incidencija dijabetesa tip 1 u stalnom je porastu te se u dostupnim podacima vidi porast oboljelih. U razdoblju 1990.-2000. bilo je 28 oboljelih, u razdoblju 2001.-2009. bilo je 38 oboljelih, dok je u razdoblju 2010.-2020. broj oboljelih 51. Istraživanjem nije dokazana statistički značajna razlika u spolu kao predispozicija za oboljenje. Genetski čimbenici su važni, ali nisu presudni za nastanak bolesti. U provedenom istraživanju oboljela djeca su se pridržavala zdravstvenih preporuka i redovito odlazila na kontrole liječniku.Type 1 diabetes is a chronic metabolic disorder that leads to hiperglycemia. In children, as in adults, energy metabolism is disrupted due to insufficient secretion of insulin or due to its insufficient effect, which affects the metabolism of carbohydrates, fats and proteins. It occurs in childhood and adolescence. World research data show that an average of 86,000 children in the world get sick each year.
The aim of the research: was to investigate the incidence of type 1 diabetes in a 10-year period in the Dubrovnik-Neretva County. The research determined which children's age has the highest number of established diseases, there is a difference in the incidence of the disease according to the sex of the child, and there was a genetic predisposition for the disease in sick children. The research determined how many patients follow health instructions, and how often they go to see a doctor.
Subjects and methods: The study was conducted by retrospective analysis of insights into the medical history of patients at the Department of Pediatrics in OB Dubrovnik over a 10-year period. In addition to the available numerical data from the history of the disease, a questionnaire was constructed according to the set goal and was conducted among the parents of sick children.
Conclusion: Globally, the incidence of type 1 diabetes is constantly increasing and the data show an increase in the number of patients. In the period 1990.-2000. there were 28 patients, in the period 2001.-2009. there were 38 patients, while in the period 2010.-2020. the number of patients is 51. The study didn't prove a statistically significant difference in gender as a predisposition to the disease. Genetic factors are important, but they are not crucial for the development of the disease. In the conducted research, sick children adhered to health recommendations and regularly went to the doctor for check-ups
Transport of Scrap Metal by Sea
No full textStaro željezo ili metalni otpad danas je globalna roba kojom se, a zbog potrebe
industrije recikliranja metala, trguje u cijelom svijetu. Najekonomičniji način transporta
navedene robe je morskim putem, a zbog niže cijene pomorskog transporta u odnosu na druge
vrste transporta, te zbog velike nosivosti brodova i mogućnosti transporta velikih količina
robe. Staro željezo ili metalni otpad se prevozi u rasutom stanju brodovima za prijevoz
rasutog tereta, ali i u kontejnerima. Za manipulaciju prilikom utovara i istovara koriste se
različita manipulativna sredstva, najčešće grabilice. Željezni otpad može biti opasan teret ako
se posada broda ne pridržava mjera sigurnosti prilikom rukovanja i prijevoza tereta. U radu su
opisane vrste željeznog otpada i rizici njegovog prijevoza, te su navedene preporuke za
siguran i učinkovit prijevoz.Scrap iron or scrap metal is today a global commodity that is traded worldwide due to
the needs of the metal recycling industry. The most economical way of transporting these
goods is by sea, due to the lower cost of maritime transport compared to other modes of
transport, and due to the high carrying capacity of vessels and their ability to transport large
quantities of goods. Scrap iron or scrap metal is transported in bulk by bulk carriers, but also
in containers. Various cargo handling equipment is used during loading and unloading
operations, mostly grabs. Scrap iron can be a dangerous cargo if the ship's crew does not
adhere to safety measures when handling and transporting the cargo. The thesis describes the
types of scrap iron, the risks of its transport and provides recommendations for safe and
efficient transport

Expert system for assessment of safety of ship navigation in port and anchorage possibilities
No full textSmanjena sigurnost odvijanja plovidbe je učestali problem koji se javlja u pomorskom prometu. Prisutno je više čimbenika, koji u određenoj mjeri imaju utjecaj. U ovom radu, naglašeni su elementi koji djeluju na sigurnost plovidbe i mogućnosti sidrenja brodova, te je izvršena njihova analiza. Dubrovački akvatorij je područje koje je detaljnije istraženo za navedeni problem. Opisani su potencijalni rizici i sigurnost plovidbe za tri mjesta sidrenja: luku Gruž, kanal Daksu i sidrište Lokrum. Također, istaknuti su ključni čimbenici i njihove granične vrijednosti za dozvoljeno sidrenje. Da bi se izbjegli potencijalni rizici i opasnosti, važno je izvršiti procjenu. Za pomoć u procjeni, osmišljen je algoritam primjenom modela stabla odlučivanja. S obzirom na dostupni algoritam, izrađen je ekspertni sustav, koji olakšava cijeli proces procjene i odlučivanja. U radu je detaljnije objašnjena primjena ekspertnih sustava. Za dizajn i implementaciju ekspertnog sustava korišten je programski jezik CLIPS.Reduced safety of navigation is a common problem that occurs in maritime transport. There are several factors present, which have an impact to some extent. In this paper, the elements that affect the safety of navigation and the possibility of anchoring ships are emphasized, and their analysis is performed. The Dubrovnik's aquatorium is an area that has been researched in more detail for this problem. The potential risks and safety of navigation are described for three anchorages: the port of Gruž, the Daksa canal and the Lokrum anchorage. The key factors and their limit values for permitted anchoring are also highlighted. To avoid potential risks and dangers, it is important to make an assessment. To aid in the estimation, an algorithm was developed using a decision tree model. Given the designed algorithm, an expert system has been developed that facilitates the entire process of assessment and decision-making. The paper explains in more detail the application of expert systems. The CLIPS programming language was used to design and implement the expert system
