ABSTRACTJavelin throw is a complex athletic discipline that requires several years of training to master a throw technique. Since teachers are time-limited, problem occuring in the teaching is how to train students to proper javelin throw technique as quickly as possible. Given that it is difficult to master a javelin as prop, research has been conducted to determine efficiency of vortex application as auxiliary prop in javelin throw technique training. The total number of respondents were 30 students of the first year of undergraduate Kinesiology study at University of Mostar in academic year 2016/2017. The initial measurement was made at the beginning of the classes. During the classes general exercises were used as well as vortex application as auxiliary prop in throw technique training. The final measurement and evaluation of javelin throw technique was made by three referees at the end of classes. Statistically significant difference between the initial (31,1m) and final (33,9) measurement was obtained by using the T-test . Results show that students have improved an average score in the final comparing to the initial measurement and based on obtained results it can be concluded that use of vortex has a positive effect on javelin throw training for beginners and it would be beneficial to include the prop in teaching when training students as well as younger children.
Most used laminated glass is composed of float glass plies bonded together with a viscoelastic Polyvinyl Butyral (PVB) interlayer. The shear stiffness of the polymeric interlayer is the key factor in the behavior of laminated glass. Structural engineers in the past were designing laminated glass regardless of the shear coupling of the plies. This approach with a high level of reliability led to expensive laminated glass structures due to insufficient knowledge of foil properties. Most of the current standards suggest methods that consider the shear coupling of the plies. This paper presents the experimental data from a static loading test performed on a laminated glass panel exposed to changing temperatures. The deformations were observed for 48 h. The measured results were compared with the known analytical design approaches and in addition with the finite element modeling (FEM) analysis in the available software for laminated glass design. A simplified design approach that simulates foil behavior in dependence on load duration and temperature change was adopted in this study. Design approaches that use effective thickness calculations are used with the Young and shear relaxation modulus provided by the foil producer. The imprecision of the Eurocode standards for glass design, and the propensity to change the approach to the calculation by introducing more precise parameters were expounded. The results when combining the time-temperature superposition (TTS) and the Wölfel–Bennison approach were found to be in very good agreement with the FEM analysis of 3D solid elements in Abaqus and measured data.
Apstrakt:Gradski kontrolni ured Grada Zagreba i Kontrolni ured Grada Beča obavili su horizontalnu Reviziju financiranja sporta radi procjene uspostavljenog sustava unutarnjih kontrola, davanja stručnog mišljenja i preporuka za unapređenje sustava. Revizija je obavljena po metodologiji za obavljanje unutarnje revizije Ministarstva financija. Zajedničke karakteristike procesa financiranja sporta u Zagrebu i Beču su: procedure i pravila za dodjelu sredstava za provođenje sportskih programa, sustav unutarnjih kontrola kojim se osigurava transparentna raspodjela sredstava, dokumentirane faze raspodjele sredstava. U Gradu Zagrebu postoji mogućnost za unapređenje sustava unutarnjih kontrola u procesima raspodjele sredstava za velike sportske priredbe i praćenja namjenskog korištenja sredstava za realizaciju programa sporta. Nositeljima revidiranog procesa predloženo je propisivanje kriterija za raspodjelu sredstava za velike sportske priredbe i implementiranje jedinstvenog informatičkog rješenja za proces raspodjele i kontrole namjenskog korištenja sredstava za provedbu programa javnih. Ključne reči:sustav unutarnjih kontrola, javne potrebe u sportu, namjensko korištenje proračunskih sredstava. E-mail: indira.cizmic@zagreb.hr UVODMetodologija, standardi, odnosi i odgovornosti te nadležnosti korisnika proračuna u provedbi sustava unutarnjih fi nancijskih kontrola u javnom sektoru Republike Hrvatske propisani su 2005. godine Zakonom o sustavu unutarnjih financijskih kontrola u javnom sektoru. Novi Zakon o sustavu unutarnjih kontrola u javnom sektoru donesen je sredinom 2015. godine. Sustav unutarnjih fi nancijskih kontrola obuhvaća fi nancijsko upravljanje i kontrole te unutarnju reviziju. Svrha uspostave fi nancijskog upravljanja i kontrola je unaprjeđenje uspostavljenih kontrolnih mehanizama temeljem kojih čelnici korisnika proračuna donose odluke o korištenju proračunskih sredstava radi postizanja općih ciljeva. U javnoj upravi Republike Hrvatske sustav unutarnjih fi nancijskih kontrola u praksi se provodi kroz tri elementa: fi nancijsko upravljanje i kontrole, funkcionalno neovisnu unutarnju reviziju i Središnju harmonizacijsku jedinicu Ministarstva fi nancija, koja ima ulogu koordinatora aktivnosti korisnika proračuna pri uspostavi i razvoju sustava unutarnjih fi nancijskih kontrola za javni sektor.Proces usklađivanja sustava unutarnjih fi nancijskih kontrola s međunarodno priznatim praksama javnog upravljanja i prema pravnoj stečevini Europske zajednice u Gradu Zagrebu pokrenut je u lipnju 2005. godine ustrojavanjem Gradskog kontrolnog ureda nadležnog za obavljanje poslova unutarnje revizije gradskih upravnih tijela, tijela Grada Zagreba, tijela mjesne samouprave i proračunskih korisnika.Budući da je 2005. godine unutarnja revizija kao profesija u javnom sektoru bila "novost" na svim razinama u Republici Hrvatskoj, radi afi rmiranja unutarnjih revizora u Gradu Zagrebu, Gradski kontrolni ured (koji je ustrojen po modelu koji funkcionira u Gradu Beču) je 2005. godine počeo suradnju s Kontrolnim uredom Grada Beča.
