5) Pokazala se statistički značajna razlika između potrebnog vremena 2a sječu i izradu drva utvrđenog po Sistemu THV i onog izračunatog po normama Šumskog gospodarstva »Josip Kozarac«. 6) Pokazala se signifikantna razlika između radnog vremena koje radnici stvarno troše pri radu i onog vremena koje se radnicima priznaje prema normama Šumskog gospodarstva »Josip Kozarac«. 7) Postoji mogućnost da predviđeni obujam sječe i izrade drva izvrši s manjim brojem radnika bez opasnosti po zdravlje radnika. Primjena Sistema THV omogućuje racionalno korištenje i objektivniju raspodjelu osobnih dohodaka prema rezultatima rada.

Summary Possibilities an Applying Working Time Determination for Cutting and Primary Conversion of Wood in the Forest Enterprise »Josip Kozarac«, Nova Gradiška, The research results have been used for testing the applicability of the THV System for the Forest Enterprise »Josip Kozarac«, Nova Gradiška. The testing was done od 32 felling subsites scattered throughhout the forest ma nagement area, with 9,187 trees alloted for felling. Prior to felling, the authors gave a THV estimate of times needed for cutting and primary conversion of wood. The allotted trees were then cut down and preparen into timber assortments totaling 9,522 ms of net timber quantity, whererby the cutting and primary conversion of wood spent by workmen on each felling su´bsite wass measured. This was followed by the authors´ computation of times the workmen needid for felling and preparing the net timber quantity. On the other hand, the wages standards normally applied at »Josip Kozarac« were worked out in terms of times being actually allotted to the workmen for cutting and primary conversion of wood. The THV time estimates prior to felling and the obtained THV times after felling, the actually used felling and timber-preparation times, and the standard times being corectly approved by forest management were compared. The t-testing in pairs did not show statistically significant differences between the THV time |
