FIRE PROTECTION IN THE MALA KAPELA TUNNEL
No full textTuneli su uređeni prokopi cjevastog oblika kroz tlo ili stijenu. Njime se savladava prirodna prepreka ili skraćuje duljina puta, a služi kao prolaza ceste, željezničke pruge, plovnog puta ili pješačke staze. U Republici Hrvatskoj najduži cestovni tuneli su Mala Kapela i Sveti Rok koji se nalaze na autocesti A1. U ovom radu bavit ću se sigurnošću prometa kroz tunel Mala Kapela i opremom koja je u isti ugrađena glede sigurnosti za slučaj nastanka požara ili drugih incidentnih situacija. Pokušat će detaljno opisati instalacije koje su ugrađene u tunel od strojarskih ( ventilacija, hidrantska mreža, i odvodnja) do sustava zaštite od požara i spašavanja (sustav za dojavu požara, telefonsko pozivni sustav, radio sustav, sustav ozvučenja, sustav video nadzora, mjerenje vidljivosti i CO). Djelom je prikazan rad Vatrogasne postaje Mala Kapela pod čijom je nadležnošću tunel Mala Kapela.Tunnels are organized tube-shaped excavations through the ground or rock. It overcomes a natural obstacle or shortens the length of the road, and serves as a road, railway, waterway, or footpath. In the Republic of Croatia, the longest roads are mala Kapela and Sveti Rok, which are located on the A1 highway. In this paper, I will deal with the safety of traffic through the Mala Kapela tunnel and the equipment that is installed in it regarding safety in the event of a fire or other incident situations. I will try to describe in detail the installations installed in the tunnel, from mechanical (ventilation, hydrant network, and drainage) to fire protection and rescue systems (fire alarm system, telephone call system, radio system, sound system, video surveillance system, visibility measurement and CO). Partially there is shown the work of the fire station Mala Kapela in whose jurisdiction is the Mala Kapela tunnel

No full textU završnom radu analizirane su trofejne vrijednosti srnjaka u zajedničkom otvorenom lovištu broj: III/112 Gojlo, kojim gospodari Lovačka udruga „Fazan“ Kutina. Radi se o lovištu ukupne površine 6504 hektara, koje spada u nizinsko-brdsko lovište s nadmorskim visinama od 98,2- 237 mnv. do e Za analizu su korišteni sljedeći čimbenici: duljina rogova, masa rogova, volumen rogova, raspon rogova, dob, trofejna vrijednost, te predio odstrjela. Analizom su obuhvaćene lovne godine od 2013./2014. do 2020./2021. Za potrebe analize korištena je lovno gospodarska osnova (LGO), evidencija trofeja divljači (ETD obrasci) i 106 ocjembenih listova. Na temelju rezultata može se konstatirati kako konačna ocjena trofeje (broj CIC točaka) raste paralelno sa dobi jedinke, te ovisi o terenu odstrjela srnjaka, a varira od godine do godine. Unatoč tome u zajedničkom otvorenom lovištu Gojlo u promatranih osam lovnih godina imamo 12 trofeja koji su ocijenjeni sa medaljom, 9 bronci i 3 srebra. U lovištu se svake lovne godine odstrijeli srnjak koji ostvari više od 100,00 CIC točaka.These study analyzed trophy values of roe deer in common open hunting ground number: III/112 Gojlo, which is under management of hunting association „Fazan“ Kutina. Hunting ground surface area is 6504 hectares and it belongs to the lowland-mountain hunting grounds. In the central part of hunting ground highest peeks exceed 200 meters above sea level - the highest peek is 237 meters above sea level, while the lowest part of the hunting ground is at 98,2 meters above sea level. For the analysis, the following factors were used: antler length (average), trophy weight, antler volumen, antler span, age, trophy value (CIC points) and the locations where the deer were shot. Analysis has covered hunting years from 2013./2014. to 2019./2020. It is based on hunting managment document (LGO), ETD forms and 106 trophy measurement forms. Based on results, conclusion is that final rating of roe deer trophy (number of CIC points) increases with the age of individual and depends on the terrain where roe deer was hunted down. Also it variates from year to year. Despite this, in joint open hunting ground Gojlo in eight hunting seasons 12 trophies have been evaluated with medals, of which 9 bronze and 2 silver ones. In the above mentioned hunting ground, a roe deer with more than 100,00 CIC points hunted down each hunting season
ANNUAL OVERHAUL OF THE POOL COMPLEX-MAINTENANCE OF THE SAND FILTER
No full textBazen je objekt s umjetno zatvorenom vodenom masom koji se koristi za sport, rekreaciju i relaksiranje. Mogu biti različitih dimenzija, a jedini bazen standardnih dimenzija je natjecateljski tzv. olimpijski bazeni, širine 25 m i dužine 50 m. Danas vrlo popularne bazenske komplekse uglavnom čini skupina nekoliko bazena, od čega je jedan većih, a ostali manjih dimenzija. Kompleksi najčešće nude i brojne dodatne sadržaje kao što su saune, jacuzzi, fontane, dječji vodeni park, sunčališta i slično. Javni bazeni projektiraju se prema DIN normi. Ona ima ključnu ulogu u pročišćivanju, filtriranju i osiguravanju visoke kvalitete vode u bazenima. Osim kvalitete vode te sanitarno-tehnički i higijenski uvjeta, norme također definiraju projektiranje, rad i nadzor kupališta. U skladu s propisima nužno je obavljati redovito analizu vode. Kvalitetu bazenskih voda je potrebno kontrolirati sa zdravstvenog, estetskog i tehničkog stajališta jer je zdravstveno ispravna voda za kupanje jedan od prioriteta u sprečavanju bolesti koje se prenose vodom. Cjelokupni kompleks sačinjen je on nekoliko komponenti koje imaju vrlo važnu ulogu kako u funkcioniranju tako i u održavanju istog. Svaki bazen mora obavezno imati strojarnicu ili filtracijsku postaju, toplinsko postrojenje, ventilacijski sustav te bazensku tehniku. Pojam bazenska tehnika obuhvaća čitav niz instalacija i uređaja koji služe za održavanje bazenske vode. Njihov zadatak je održavanje vode čistom, zagrijavanje vode, kontrola i regulacija bazenskih sustava. Bazenske komplekse potrebno je redovno servisirati i održavati te pridržavati se brojnih zakonom propisanih pravila. Kako bi sve moglo dobro funkcionirati održavanje se obavlja prema točno propisanom planu. U praktičnom dijelu rada prikazat ću primjer godišnjeg čišćenja i dezinfekcije pješčanog filtera za olimpijski bazen na Bazenskom kompleksu Svetice.A swimming pool is an object with an artificially closed body of water that is used for sports, recreation and relaxation. They can be of different dimensions, and the only pool of standard dimensions is the so-called competitive pool. olympic swimming pools, 25 m wide and 50 m long. Nowadays, very popular swimming pool complexes mainly consist of a group of several pools, one of which is larger and the others smaller. Complexes usually offer numerous additional facilities such as saunas, jacuzzis, fountains, children's water park, sunbathing areas and the like. Public swimming pools are designed according to the DIN standard. It plays a key role in purifying, filtering and ensuring high quality water in swimming pools. In addition to water quality and sanitary-technical and hygienic conditions, the norms also define the design, operation and supervision of swimming pools. In accordance with the regulations, it is necessary to carry out regular water analysis. The quality of pool water needs to be controlled from a health, aesthetic and technical point of view, because healthy bathing water is one of the priorities in preventing water-borne diseases. The entire complex is made up of several components that play a very important role both in its functioning and in its maintenance. Every swimming pool must necessarily have an engine room or a filtration station, a heating plant, a ventilation system and pool technology. The term pool equipment includes a whole series of installations and devices that serve to maintain pool water. Their task is to keep the water clean, heat the water, control and regulate the pool systems. Pool complexes need to be regularly serviced and maintained, and numerous rules prescribed by law must be followed. In order for everything to function well, maintenance is carried out according to the precisely prescribed plan. In the practical part of the paper, I will present an example of the annual cleaning and disinfection of the sand filter for the Olympic swimming pool at the Svetice Swimming Pool Complex
MONITORING OF FELIDS IN HUNTING GROUND IV/3-BUKOVAČA BY USING CAMERA TRAPS
No full textEuroazijski ris (Lynx Lynx) i divlja mačka (Felis silvestris) su jedini divlji predstavnici porodice Felida na području Republike Hrvatske. Kako se radi o skrovitim vrstama koje se teško uočavaju, fotozamke su vrijedan alat u njihovom istraživanju, posebice kada su postavljene na lokacije na kojima markiraju. Monitoring felida na području lovišta IV/3 „Bukovača“ uz pomoć fotozamki, realiziran je pomoću projekta „LIFE Lynx“, koji je proveden od veljače 2022. godine do rujna 2022. godine. Projekt LIFE Lynx provodi se 01.07.2017. god. – 31.03.2024. god. na područjima država Italije, Slovenije i Hrvatske a za svrhu ima očuvanje stabilne populacije i sprečavanje izumiranja risa l (Lynx lynx). Na pet odabranih lokacija unutar lovišta postavljene su fotozamke pri čemu se najviše nastojalo postavljati fotozamke na prepoznata i moguća markirališta, ponajviše napuštene objekte kao što su drvene kuće, betonske nadstrešnice i limeni kontejneri. U okviru ovog istraživanja prikupljeno je ukupno 25 fotografija i 3 videozapisa divljih i domaćih mačaka. Risovi nisu zabilježeni, što ide u prilog dosadašnjim spoznajama o rijetkoj prosutnosti euroazijskog risa na području ovog lovišta. KThe Eurasian lynx (Lynx Lynx) and the European wildcat (Felis silvestris) are the only wild representatives of the Felidae family on the territory of the Republic of Croatia. As they are secretive species that are difficult to spot, photo traps are a valuable tool in their research, especially when they are placed in locations where they mark. Monitoring of felids in the area of hunting ground IV/3 "Bukovača" with the help of photo traps was realized by means of the "LIFE Lynx" project, which was carried out from February 2022 to September 2022. The LIFE Lynx project is implemented on July 1, 2017. year – 31.03.2024. year in the territories of the countries of Italy, Slovenia and Croatia, and its purpose is to preserve a stable population and prevent the extinction of the lynx (Lynx lynx). Phototraps were placed at five selected locations within the hunting grounds, with the greatest effort being made to place phototraps at recognized and possible marking sites, mostly abandoned buildings such as wooden houses, concrete canopies and tin containers. A total of 25 photos and 3 videos of wild and domestic cats were collected as part of this research. No lynxes were recorded, which is in support of previous knowledge about the rare occurrence of Eurasian lynx in the area of this hunting ground
FIREFIGHTING INTERVENTION MANAGEMENT
No full textU ovom završnom radu prikazani su počeci razvoja i implementacija programskog rješenja UVI – Upravljanje u vatrogasnim intervencijama. Radi ukazane potrebe za unificiranim softverskim rješenjem odnosno osigurati vatrogascima operativni IK alat koji će biti potpora u vođenju intervencija i donošenju odluka. U radu je opisano polazište projekta, zašto se i kako je došlo do UVI-a, te očekivani doprinos radu i cilj. Kako je UVI jedan od najkompleksnijih IK rješenja, svi sustavi koji postoje su se na neki način integrirali u UVI, neki kao izvori podataka, neki kao operativna potpora sustavu UVI. Za početak morala se stvoriti baza podataka što je postignuto obaveznim upisom svih relevantnih podataka vatrogasnih organizacija u VATRONET,a što je naposljetku izvor podataka za UVI. U radu su sagledane glavne prednosti i nedostaci ovog programskog rješenja te dane preporuke za eventualna unaprjeđenja.IV SUMMARY In this paper, the beginnings of the development and implementation of the program solution UVI - Management in fire interventions are presented. Due to the stated need for a unified software solution, that is, to provide firefighters with an operational ICT tool that will be a support in conducting interventions and making decisions. The paper describes the starting point of the project, why and how UVI came about, as well as the expected contribution to the work and the goal. As UVI is one of the most complex ICT solutions, all existing systems have somehow been integrated into UVI, some as data sources, some as operational support for the UVI system. To begin with, a database had to be created, which was achieved by mandatory entry of all relevant data of firefighting organizations into the VATRONET application, which was ultimately the source of data for UVI. The paper examines the main advantages and disadvantages of this software solution and gives recommendations for possible improvements

IMPLEMENTACIJA ZELENOG MARKETINGA NA PRIMJERU POSLOVANJA HOTELA U HRVATSKOJ I ŠVEDSKOJ
No full textU današnje vrijeme briga za okoliš je počela biti imperativ kako bi se on očuvao. Čovjek postaje
sve svjesniji svog utjecaja na prirodu i okoliš, koji se znatno promijenio eksploatacijom i
degradacijom prostora, uništavanjem šuma, izgradnjom urbanističkih gradova, emisijom
štetnih plinova, napretkom industrije i ostalim utjecajima koji su se negativno odrazili na
okoliš. Industrijalizacija je itekako važna za gospodarstvo, ali uz napredak industrije dolazi i
narušavanje ekosustava. Nezainteresiranost za očuvanje okoliša predstavlja jedan od najvećih
problema današnjice, ponajviše u gospodarstvu. S druge strane, postoji ekološka svijest koja
potiče poduzeća da svoje poslovanje usmjere ka očuvanju prirode. Implementacijom održivog
razvoja i zelenog načina razmišljanja u poslovanju, smanjuje se negativan utjecaj na okoliš, a
time se poboljšava zdravlje čovjeka i kvaliteta života. Poduzeća koja odluče poslovati održivim
načinom, pridržavaju se propisanih zakona i standarda koji daju veliki poticaj u širenju svijesti
za očuvanje okoliša, ali i na strukturiran način pristupanju velikom problemu u gospodarstvu,
također od velike važnosti je napomenuti i konkurentnost na tržištu ukoliko poslovanje
obuhvaća održivi način poslovanja. Jačanje ekološke svijesti mijenja i način razmišljanja
potrošača, što dovodi do promjene mentaliteta i stvaranje „zelenih“ potrošača. Takvi potrošači
su spremni odvojiti više novca i platiti veću cijenu za proizvod ili uslugu koji su prikazani kao
ekološki prihvatljivi. Na ovom tržišnom segmentu počiva pojam i koncept „zelenog
marketinga“, koji predstavlja zadovoljavanje potreba ekološki osviještenih potrošača. U
turizmu, uloga marketinga je od izuzetne važnosti, jer turizam ovisi o okolišu iz razloga što ga
istodobno koristi kao najveći i najvrjedniji resurs. Implementacija koncepcije zelenog
marketinga u turizam je ključna zbog masovnog turizma koji svojim bujanjem direktno ostavlja
negativne posljedice na okoliš, te narušava održivost i degradira atraktivne destinacije. Ovaj
rad će obrazložiti utjecaj zelenog marketinga u turizmu kroz inicijativu hotelskih poduzeća
koja su odlučila implementirati održivost i zeleno poslovanje kako bi turizam bio što
dugoročnija djelatnost, dok pritom čuva okoliš i čini ga održivim.Nowadays, care for the environment has become imperative in order to preserve it. People are
becoming more and more aware of his impact on nature and the environment, which has
changed significantly due to the exploitation and degradation of space, the destruction of
forests, the construction of urban cities, the emission of harmful gases, the progress of industry
and other impacts that have had negative impact on the environment. Industrialization is also
important for the economy, but with industrial progress comes ecosystem disruption. Lack of
interest in environmental protection is one of the biggest problems today, especially in the
economy. On the other hand, there is environmental awareness that encourages companies to
direct their operations towards nature conservation. By implementing sustainable development
and a green way of thinking in business, the negative impact on the environment is reduced,
thereby improving health and quality of life. Companies that decide to do business in a
sustainable way, adhere to the legal acts and standards that give a great incentive in spreading
awareness for environmental protection, but also approach a major problem in the economy in
a structured way. It is of great importance to note competitiveness on the market if the business
includes sustainability. Strengthening environmental awareness also changes the way
consumers think, which leads to a change in mentality and the creation of „green“ consumers.
Such consumers are willing to give more money and pay a higher prices for product or service
that is presented as environmentally friendly. The term and concept of „green marketing“ rests
on this market segment, which represents meeting the needs of environmentally conscious
consumers. In tourism, the role of marketing is extremely important, because tourism depends
on the environment and simultaneously uses it as the largest and most valuable resource. The
implementation of the concept of green marketing in tourism is crucial because of mass
tourism, which directly leaves negative consequences on the environment and damages
sustainability with degrading attractive destinations. This thesis will explain the impact of
green marketing in tourism through the initiative of hotel companies that decided to implement
sustainability and green business in order to make tourism a long-term activity, while
preserving the environment and making it sustainable
