Impact of different agricultural operations on produced mechanical vibrations that affect the operator hand-arm system in relation to the working hours of tractor

U radu su prikazani rezultati mjerenja istraţivanja rukovatelja strojem s obzirom na broj radnih sati istog stroja tijekom dvije agrotehničke sezone mjerenja. Izmjerene su razine traktorskih vibracija koje djeluju na sustav ruka - šaka rukovatelja pri različitim agrotehničkim podlogama u skladu s propisanim normama HRN ISO 2631-1, HRN ISO 5349-1 i HRN ISO 5349-2. Sva mjerenja su obavljena na traktoru proizvoĎača LANDINI tipa POWERFARM 100 na proizvodnim površinama i pristupnim cestama srednje Poljoprivredne i veterinarske škole Osijek. Mjerenja su obavljana ureĎajem za mjerenje vibracija MMF VM30 koje utječu na sustav ruka - šaka. Rezultati istraţivanja ne prelaze dopuštene vrijednosti vibracija koje utječu na sustav ruka – šaka rukovatelja poljoprivrednog traktora niti će ugroziti njegovo zdravlje.The paper presents the results of the survey of the operator of the machine according to the number of working hours of the same machine during the two agro-seasonal measurements. The levels of traction vibrations measured on the arm system of handlers are measured at different agrotechnical surfaces in accordance with the prescribed standards HRN ISO 2631-1, HRN ISO 5349-1 and HRN ISO 5349-2. All measurements were made on the tractor of the LANDINI type POWERFARM 100 on production areas and access roads of the Central Agricultural and Veterinary School Osijek. The measurements were performed by an IMF VM30 vibration measuring device which affects the hand - arm system. The results of the research do not exceed the permissible vibration values which affect the hand - arm of the operator of the agricultural tractor or will jeopardize its healt

Identity-Role Relationship in Intetrnational Relations and Foreign Policy: Ontology, Epistemology and Methodology

Cilj ovog rada je da omogući temeljan uvid u ključne teorijske rasprave u vezi sa odnosom identiteta i uloga u disciplini međunarodnih odnosa i analizi spoljne politike, s posebnim fokusom na teorijske pristupe socijalnog konstruktivizma i teorije spoljnopolitičkih uloga. Imajući u vidu odsustvo interesovanja za ovaj pristup istraživanju u regionalnoj akademskoj literaturi, sistematizujem tri dimenzije proučavanja uloga u spoljnoj i bezbednosnoj politici: ontološku, epistemološku i metodološku. U ovom nastojanju da se prokrči put daljim istraživanjima, poseban naglasak se stavlja na uloge malih država u svetskoj politici između strukturnih imperativa i mogućnosti delatništva. Teorija uloga se sagledava u svom odnosu prema konsturktivističkoj analizi spoljne politike, pri čemu se ukazuje na osnovne pojmove teorije uloga, interpretativnu metodologiju i neke primere istraživanja diskurzivnog konstruisanja identiteta i uloga država. U zaključku se osvrćem na neka dalja pitanja i jednu istraživačku agendu identiteta i uloga u međunarodnim odnosima.The aim of this article is to enable a comprehensive insight into key theoretical debates on the relationship between identities and roles in International Relations (IR) and Foreign Policy Analysis (FPA), with a particular focus on theoretical approaches of social constructivism and foreign policy role theory. Given the lack of interest in this research approach the post-Yugoslav IR literature, I systematize ontological, epistemological and methodological dimensions of studying foreign policy and security roles of states. In this research path-breaking effort, a special emphasis is on the role of small states in world politics between structural imperatives and possibilities of agency. Role the- ory is reviewed in its relationship toward constructivist FPA, whereas the key notions of role theory, interpretive methodology and some examples of re - search on discursive construction of state identity and roles are presented. In the conclusion, I reflect on some further questions and a research agenda of identity and roles in IR
