    Cilj ovog rada jest ukazati na iznimnu važnost procesa proračunskog planiranja i odgovornog fiskalnog ponaÅ”anja, kako bi se promijenila praksa učestalih potreba za rebalansom državnog proračuna. U odnosu na dosadaÅ”nje rebalanse, posljednji je specifičan utoliko Å”to je potaknut procedurom pri prekomjernom proračunskom deficitu (Excessive Deficit Procedure ā€“ EDP). Naime, zajednički uzrok svih hrvatskih rebalansa jest nekontrolirana budžetska potroÅ”nja, koja se iz godine u godinu pretače kroz kumulative ostvarenih deficita u zabrinjavajuću dinamiku porasta javnog duga. Ako tu činjenicu smjestimo u kontekst petogodiÅ”nje recesije, onda je očito da je fiskalna politika svojim (ne)djelovanjem produbila krizu koja je dvostruko uvjetovana: domaćim strukturnim problemima te krizom zemalja partnera. Stoga ovaj rad, analizirajući osnovne agregate iz rebalansa državnog proračuna za 2014. godinu, donosi zaključak o dobrobiti EDP-a za Hrvatsku jer se po prvi puta kao zemlja članica EU-a Hrvatska suočava s vlastitim strukturnim problemima koji su se do sada u pravilu tretirali parcijalno i nesustavno, bez potrebne stručne ekspertize i političke volje da se prekine neodrživa fiskalna praksa.The main purpose of this paper is to stress the importance of the budget planning process and responsible fiscal attitude in order to reduce the practice of frequent budget revisions. Compared to the previous budget revisions, the last one was specific because it had been induced by the Excessive Deficit Procedure. However, the common cause of each budget revision has been excessive government spending which cumulated fiscal deficits leading to unsustainable dynamics of public debt growth. Considering this fact in the context of a five-year recession and overall economic contraction, the fiscal policy has obviously deepened the macroeconomic crisis determined by domestic structural problems and by the global crisis. This paper analyzes the main aggregates of the state budget revision for 2014 and draws conclusions on the overall benefit of the EDP. For the first time, Croatia as an EU member tackles its own structural problems that have generally been treated partially and unsystematically, without necessary professional expertise and political will to end the unsustainable fiscal practices

    The occurrence, seasonal and vertical distribution of bisphenol A (BPA) was investigated in the sediments and suspended matter sampled in KaÅ”tela Bay, Adriatic Sea, Croatia. Granulometric composition of sediment and organic matter (OM) in sediments and suspended matter were also examined. BPA was detected in all samples of sediments and suspended matter. Concentration of BPA in sediment ranged from 5.32 Ī¼g kg-1 to 15.52 Ī¼g kg-1, while in suspended matter BPA ranged from4.66 Ī¼g kg-1 to 103.06 Ī¼g kg-1. Seasonality in distribution of BPA concentrations in sediment and suspended matter was not found. The most abundant grain size fractions in sediment were silt (64.40Ā±8.63%) and sand (26.97Ā±9.11%) with accordingly determined sediment type as sandy silt. Average content of OM was 12.01Ā±1.85% and 12.51Ā±1.30%, for sediment and suspended matter, respectively. Monthly distribution of OM content showed higher values during October-March period and lower values during April-September period, while for the suspended matter situation was opposite. Statistical analysis of obtained data showed no existing significant correlation between concentration of BPA in sediments and suspended matter, or between BPA concentration and OM in sediments and suspended matter.Prisustvo te sezonska i vertikalna raspodjela BPA istraživani su u sedimentu i suspendiranoj tvari prikupljenima u KaÅ”telanskom zaljevu, Jadransko more, Hrvatska. U uzorcima je određena koncen -tracija BPA, granulometrijski sastav sedimenta te sadržaj organske tvari (OM) u sedimentu i suspendiranoj tvari. BPA je pronađen u svim uzorcima sedimenta i suspendirane tvari, a koncentracije BPA u sedimentu su bile u rasponu od 5.32 Ī¼g kg-1do 15.52 Ī¼g kg-1, u suspendiranoj tvari od 4.66 Ī¼g kg-1 do 103.06 Ī¼g kg-1. Nije ustanovljena sezonska raspodjela BPA u uzorcima suspendirane tvari i sedimenta. Analizom udjela pojedinih veličinskih frakcija sediment je klasificiran kao pjeskoviti silt. Prosječni udio OM u sedimentu je bio 12.01Ā±1.85%, a u suspendiranoj tvari 12.51Ā±1.30%. Veći udjeli OM zabilježeni su u hladnom razdoblju godine (13.13Ā±1.32%), za razliku od toplog razdoblja kada je prosječni udio OM bio 11.56Ā±0.54%. Raspodjela OM u toplom i hladnom razdoblju u suspendiranoj tvari bila je suprotna raspodjeli ustanovljenoj za sediment. Statističkom analizom dobivenih rezultata nije ustanovljena značajna korelacija između sadržaja OM u sedimentu i suspendiranoj tvari i koncentracije BPA

    In this work, 3D visualization of a work place by means of a computer-made 3D-machine model and computer animation of a worker have been performed. By visualization of 3D characters in inverse kinematic and dynamic relation with the operating part of a machine, the biomechanic characteristics of workerā€™s body have been determined. The dimensions of a machine have been determined by an inspection of technical documentation as well as by direct measurements and recordings of the machine by camera. On the basis of measured body height of workers all relevant anthropometric measures have been determined by a computer program developed by the authors. By knowing the anthropometric measures, the vision fields and the scope zones while forming work places, exact postures of workers while performing technological procedures were determined. The minimal and maximal rotation angles and the translation of upper and lower arm which are basis for the analysis of worker burdening were analyzed. The dimensions of the seized space of a body are obtained by computer anthropometric analysis of movement, e.g. range of arms, position of legs, head, back. The influence of forming of a work place on correct postures of workers during work has been reconsidered and thus the consumption of energy and fatigue can be reduced to a minimum
