PSYCHOSOCIAL RISKS IN THE WORK OF NURSES AND TECHNICIANS
No full textPsihosocijalni rizici na radnom mjestu jedan su od vodećih izazova u radnoj organizaciji, kako za radnika tako i za poslodavca. Poslodavac je dužan provoditi prevenciju stresa na radu i izraditi procjenu rizika za psihofiziološke napore na radnim mjestima, prema Zakonu o zaštiti na radu. Svaka procjena rizika na radu, a isto tako i procjena psihosocijalnih rizika, zahtijeva podršku poslodavaca kao i sudjelovanje radnika. Samo zdravo radno mjesto i zadovoljni zaposlenici imaju veću produktivnost, postižu bolju kvalitetu rada, a time se smanjuje fluktuacija radnika. U Republici Hrvatskoj poslodavci imaju obvezu provoditi prevenciju stresa na radu od lipnja 2014. godine. Nažalost, još se uvijek ne pridaje dovoljno važnosti pitanju stresa na radnom mjestu, a ni procjeni psihosocijalnih rizika.Psychosocial risks in the workplace are one of the leading challenges in the workplace organization, eighter for the employee or for the employer. It is the employer's obligation to carry out prevention stress at work and create a risk assessment for psychophysiological efforts at workplaces. These actions are mandatory because they are prescribed by the occupational safety law. Any risk assessment at work, as well as psychosocial assessment risks requires the support of employers as well as the participation of workers. Only a healthy workplace and satisfied employees have higher productivity and thus achieve better quality of work. In such healthy environments, the turnover of workers is also reduced in this way. In the Republic of Croatia, it is the employer's obligation to implement prevention of stress at work since June 2014. Unfortunately, stress at the workplace is not taken care of enough. Also, not enough care is taken to assess psychosocial risks
STRUCTURAL AND TECHNOLOGICAL MEASURES FOR PROTECTION FROM CORROSION
No full textZadatak ovog završnog rada je zaštita strojarskih konstrukcija i dijelova od korozije pravilnim oblikovanjem kao i sprječavanje nastanka raznih oštećenja, koja mogu potaknuti nastanak korozije. U radu su izneseni razni primjeri neprimjerenih konstrukcijskih rješenja koji mogu uzrokovati nastanak korozijskih oštećenja, ali i njihove pravilne izvedbe koje mogu usporiti korozijske procese, produžiti vijek trajanja opreme, spriječiti nepoželjne troškove održavanja i neupotrebljivost cijele konstrukcije pa čak i havarije. Važno je naglasiti da je konstrukcijsko- tehnološki način zaštite od korozije samo jedan od koraka zaštite. Korozija je spontani proces te ju nije lako predvidjeti. Upravo zbog takvih osobina korozije potrebno je shvatiti da ipak postoji mogućnost za postizanje optimalne korozijske postojanosti konstrukcije samo sinergijom rada konstruktora, tehnologa i stručnjaka za koroziju pri projektiranju. Njihovim zajedničkim radom uvriježile su se neke smjernice koje je bitno pratiti od početka do kraja procesaThe task of this final thesis is the protection of mechanical structures and parts from corrosion by proper shaping, as well as the prevention of the occurrence of various damages, which can promote the occurrence of corrosion. The assignment presents various examples of inappropriate structural solutions that can cause corrosion damage, but also their correct execution that can slow down corrosion processes, extend the life of equipment, prevent undesirable maintenance costs and unusability of the entire structure and even breakdowns. It is important to emphasize that the structural-technological method of corrosion protection is only one of the protection steps. Corrosion is a spontaneous process which is not easily predictable. Because of such corrosion characteristics, it is necessary to understand that there is still a possibility to achieve optimal corrosion stability of the structure only through the synergy of the work of constructors, technologists and corrosion experts during design. Through their work, some guidelines have been established that are important to follow from the beginning to the end of the proces
SOCIALLY RESPONSIBLE OPERATIONS OF HOTEL VALAMAR
No full textDruštveno odgovorno poslovanje može se definirati različitim terminima poput održivi
razvoj, korporativna društvena odgovornost, etično poslovanje i sl. Društveno
odgovorno poslovanje skaćeno (DOP) predstavlja koncept poslovanja u kojem
poduzeća dobrovoljno i bez zakonske prisile nastoje uskladiti svoje poslovanje s
potrebama društva u najširem mogućem smislu. Društveno odgovorno poslovanje
izuzetno je bitno za rast i razvoj nekog poduzeća ne samo u turizmu nego i u ostalim
granama stoga je iznimno važno prepoznati ekonomske i sociokulturne ali i druge
promjene.
Valamar Riviera posluje već dugi niz godina, a svoje je ime zapravo dobilo 1910.
godine kada je otvoren Hotel Riviera u Poreču. Valamar Riviera nudi bogatu
turističku ponudu hotelijerstva, kampinga, Alpine&Ski te vrhunsku gastornomsku
ponudu. U nastavku rada bit će pobliže objašnjeni ekonomski aspekt poslovanja,
okolišni značaj te društvene teme te će isto biti prikazano i statističkim podacima
kako bih se dobio bolji uvod društveno odgovornog poslovanja na primjeru Valamar
Riviere.Socially responsible business can be defined by different terms such as sustainable
development, corporate social responsibility, ethical business, etc. Socially
responsible business (CSR) is a concept of business in which companies voluntarily
and without legal compulsion try to align their business with the needs of society in
the broadest possible sense. Socially responsible business is extremely important for
the growth and development of a company not only in tourism but also in other
branches, therefore it is extremely important to recognize economic and socio-
cultural as well as other changes. Valamar Riviera has been operating for many
years, and it actually got its name in 1910. when Hotel Riviera was opened in Poreč.
Valamar Riviera offers a rich tourist offer of hotels, camping, Alpine&Ski and a top
gastronomic offer. In the continuation of the work, the economic aspect of business,
the environmental significance and social issues will be explained in more detail, and
the same will be shown with statistical data in order to get a better introduction to
socially responsible business on the example of Valamar Riviera

Doris Stavljenić Diplomski rad
A comparison has been made of all the software packages used in this paper to analyse
the constructed elements. A detailed description has been given of their function and the basic
features that set them apart from each other. The basic advantages of each of them have been
stated precisely and the stated improvements point towards further development and their
specialisation. A conclusion obtained by comparing all the features as well as the advantages
and the disadvantages of the stated programmes has been added.
Moving away from the theoretical part of the paper, the practical part offers an insight
into the conducted optimization of the interior elements. The elements included in the
optimization process include a shelf, a chair, an armchair, a bathroom vanity, a frame, and a
table. The analysis started by a preliminary design and the construction of a certain element,
together with the choice of material. In the second stage a static or a dynamic analysis started,
as well as the evaluation of the calculated value data. In the final stage of the project an overview
of the real environment of the constructed element was created. This procedure provided a
visual display of an element and the way to make it fit into a designed interior. This kind of
procedure was conducted by creating a 3D visualisation which provides a realistic display and
facilitates an image of the created design in real space. Programmes including OnShape, Ansys,
V-ray and SketchUp were used to carry out the entire optimization of interior design.
In the end of the paper a key conclusion way made which was adopted based on all the
theoretical and practical skills acquired in the process of creating the paper and the construction
orientation of the master’s course
