ANALYSIS OF CORPORATE SOCIAL RESPONSIBILITY IN THE COMPANY HEINEKEN CROATIA D.O.O.
No full textDruštveno odgovorno poslovanje koncept je koji poduzeća obično koriste kako bi ispunili svoju odgovornost prema zajednicama u kojima posluju. Koncept društvene odgovornosti postao je vrlo popularan među poduzećima zbog brojnih pogodnosti koje pruža. Osim što je koristan za okoliš i društvenu zajednicu, društveno odgovorno poslovanje može pomoći i poboljšanju kvalitete poslovanja poduzeća. Ističe poduzeće u odnosu na konkurenciju, izdvaja ga iz gomile te samim time privlači više potencijalnih klijenata. Osim što pridonosi poboljšanju poslovnog učinka poduzeća, društvena odgovornost također utječe na postizanje što boljeg poslovnog uspjeha. Koncept društvene odgovornosti predstavljen je u ovom radu kako bi se pružilo dublje razumijevanje njezine važnosti u suvremenom poslovnom svijetu. Analiziranjem temeljnih odrednica ističu se različiti čimbenici koji utječu na njegovu provedbu. Jedan od najistaknutijih poduzeća koje je uspješno implementiralo ovaj koncept je Heineken Hrvatska d.o.o. Vrlo je lako uočiti da se poslovni uspjeh poduzeća može povezati s društvenom odgovornošću, što je ujedno i glavna hipoteza rada.Corporate social responsibility is a concept that companies typically use to fulfill their responsibility to the communities in which they operate. The concept of social responsibility has become very popular among companies due to the many benefits it provides. In addition to being beneficial to the environment and the community, socially responsible businesses can help and improve the quality of business operations. It emphasizes the company in relation to the competition, sets it apart from the crowd and thus attracts more potential customers. In addition to helping to improve a company's business performance, social responsibility also has the effect of achieving better business success. The concept of social responsibility is presented in this paper to provide a deeper understanding of its importance in the modern business world. Analysing the basic determinants highlights various factors that affect its implementation. One of the most prominent companies that has successfully implemented this concept is Heineken Croatia d.o.o. It is very easy to see that the business success of a company can be linked to social responsibility, which is also the main hypothesis of this paper

SAFETY SYSTEMS AND TRANSPORT OF DANGEROUS GOODS IN TUNNELS WITH ACCIDENT RECONSTRUCTION
No full textTuneli su danas najsigurniji dijelovi prometnica, svojim sigurnosnim sustavima pokrivaju svaki centimetar tunela. Današnji sofisticirani sustavi prate svako kretanje u tunelu te u realnom vremenu alarmiraju svaku neprirodnu pojavu. Današnji sustavi i oprema uvelike omogućuju olakšan pristup vatrogascima na intervencijama u tunelima, te je uspješnost intervencija u tunelima 98%. Lokacija požara u samom tunelu uvjetuje težinu intervencije, a s obzirom da se radi o takvoj građevini izvediv je frontalni ili obuhvatni nastup. Prilikom prijevoza opasnih tvari potrebno je primijeniti mjere utvrđene posebnim propisima, ishoditi potrebne dozvole, postaviti propisane znakove kako na samom vozilu tako i prije ulaska u tunel.Today, tunnels are the safest parts of the road, with their safety systems covering every inch of the tunnel. Today's sophisticated systems monitor every movement in the tunnel and alert every unnatural phenomenon in real time. Today's systems and equipment greatly facilitate firefighters' access to tunnel interventions, and the success rate of tunnel interventions is 98%. The location of the fire in the tunnel itself determines the severity of the intervention, and since it is such a building, a frontal or comprehensive appearance is feasible. When transporting dangerous goods, it is necessary to apply the measures determined by special regulations, obtain the necessary permits, place the prescribed signs both on the vehicle and before entering the tunnel
EUROPEAN WATER PROTECTION STANDARDS IN THE FEDERAL REPUBLIC OF GERMANY AND THE REPUBLIC OF CROATIA
No full textUrbanizacija, industrijalizacija, moderna poljoprivreda te sve izraženije klimatske promjene imaju izrazito negativan utjecaj na čitav okoliš pa tako i na vode. Budući da je voda ograničeni prirodni resurs bez kojeg ne bi bio moguć život na Zemlji, donošenje zakonskih okvira kojima se regulira njezina upotreba, sprječava zagađenje i kontrolira kvaliteta, od presudne je važnosti, jednako kao i njihovo provođenje. Najvažniji zakon o zaštiti voda na razini Europske unije (EU) je Okvirna direktiva o vodama (2000/60/EZ) koju su države članice preuzele u nacionalno zakonodavstvo. U ovom radu se uz prikaz važnosti vodnih resursa i europskog zakonodavstva u području zaštite voda, prije svega Okvirne direktive o vodama, predstavljaju i standardi zaštite voda u Saveznoj Republici Njemačkoj i Republici Hrvatskoj.Urbanization, industrialization, modern agriculture and increasingly pronounced climate change have a very negative impact on the entire environment and thus on water. Since water is a limited natural resource without which life on Earth would not be possible the adoption of legal frameworks regulating its use, preventing pollution and controlling quality is crucial, as is their implementation. The most important law on water protection at European Union (EU) level is the Water Framework Directive (2000/60/EC), which the member states have transposed into national legislation. This paper presents the importance of water resources and European legislation in the field of water protection, primarily the Water Framework Directive, and water protection standards in the Federal Republic of Germany and the Republic of Croatia
USE OF HELICOPTERS IN FIREFIGHTING
No full textSvakodnevno smo svjedoci nekom od požara otvorenog prostora koji nerijetko zbog klimatskih promjena, nepristupačnosti terena, jakog i olujnog vjetra, nedostatka gasitelja i tehnike, prerasta u katastrofalni požar velikih razmjera. Koji za posljedicu ima velike materijalne štete, zagađenja okoliša, velike opožarene površine a nerijetko i ljudske žrtve. Kao vrlo učinkovito sredstvo borbe sa požarima otvorenog prostora su zračne snage koje zasigurno mogu učinkovito odgovoriti na sve vrste požara otvorenog prostora a ovisne su o meteo uvjetima, nalazištu vode, aerodromima, reljefu, te samoj brojnosti eskadrile. Velika prednost zračnih snaga je u brzini odziva i njihov dolazak na samo mjesto događaja, te broj i tip samih zrakoplova.Every day we are witness to one of the fires in the open space, which, often due to climate change, inaccessibility of the terrain, strong and stormy winds, lack of fire extinguishers and equipment, turns into a catastrophic fire of large scale. Which results in great material damage, environmental pollution, large burnt areas and often human casualties. The air force is a very effective means of fighting open space fires, which can certainly respond effectively to all types of open space fires, depending on the weather conditions, the location of water, airfields, relief, and the number of squadrons. The great advantage of the Air Force is the speed of response and their arrival at the scene itself, as well as the number and type of aircraft
INFECTIOUS FOOD POISONING
No full textInfekcijsko trovanje hranom je vrlo česta, neugodna i opasna bolest koja se može dogoditi svugdje, pa tako i na radnom mjestu. Uzročnici infekcijskog trovanja hranom najčešće su bakterije i virusi, ali postoje i drugi tipovi uzročnika poput parazita te toksina biljnog ili životinjskog podrijetla. U ovom je završnom radu istražena učestalost pojave infekcijskog trovanja hranom na radnom mjestu u Republici Hrvatskoj od 2009. do 2019. godine. Učinjena je retrospektivna analiza prospektivne baze podataka (godišnja izvješća o prijavljenim ozljedama na radu koja su dostupna web stranici Hrvatskog zavoda za javno osiguranje pod ogrankom Medicina rada). S tim su ciljem statistički obrađeni podaci o ozljedama na radu uzrokovanim trovanjem i infekcijama, djelovanjem živih organizma i ozljedama koje uključuju bolesti probavnog sustava. Sektori djelatnosti u kojima su higijenski uvjeti rada niži, bilježe više slučajeva infekcijskog trovanja hranom. Ključnu ulogu u predviđanju i sprječavanju ima angažiranost uprave i svih zaposlenika u poboljšanju higijenskih uvjeta na radnom mjestu.Infectious food poisoning is a very common, unpleasant and dangerous disease that can happen anywhere, including the workplace. The most common causes of infectious food poisoning are bacteria and viruses, but there are also other types of pathogens such as primitive parasitic animals and toxins with plant or animal origin. In this final paper, the incidence of infectious food poisoning at the workplace in the Republic of Croatia from 2009 to 2019 was investigated. A retrospective analysis of the prospective database was performed (annual reports on reported injuries at work, which are available on the website of the Croatian Institute for Public Insurance under the Occupational Medicine branch). With this aim, data on work injuries caused by poisoning and infections, the action of living organisms and injuries involving diseases of the digestive system were statistically processed. Sectors of activity in which hygienic working conditions are lower, record more cases of infectious food poisoning. The key of prediction and prevention is in the engagement of management and all employees in improving hygienic conditions at the workplace
OPEN SPACE FIRE
No full textPožari otvorenog prostora sve češća su pojava u posljednja dva desetljeća, a razlog istih mogu biti brojni čimbenici od kojih je najčešći ljudski faktor, odnosno namjerno podmetanje požara u šumskim područjima. Svaka država pa tako i Republika Hrvatska ima svoju nacionalnu strategiju i plan borbe protiv požara otvorenog prostora. Vatrogasci su posebno obučeni za sve vrste požara, pa tako i za požar otvorenog prostora, a česte intervencije su u ljetnom periodu. U ovom radu analiziraju se kategorije požara otvorenog tipa, metode gašenja požara otvorenog tipa te oprema za gašenje požara otvorenog tipa.Fires in open spaces have become more common in the last two decades, and the reason for them can be many factors, the most common of which is the human factor, i.e. intentional setting of fires in forest areas. Every country, including the Republic of Croatia, has its own national strategy and plan for fighting fires in open spaces. Firefighters are specially trained for all types of fires, including fires in open spaces, and frequent interventions are in the summer period. This paper analyzes open fire categories, open fire extinguishing methods and open fire extinguishing equipment
