127. Localities and sites of the Southeastern-Alpine endemic species Spiraea decumbens Koch in Breginjski kot (Northwestern Slovenia)Marko Pavlin, Robert Brus, Igor Dakskobler, 2015, original scientific article Abstract: The eastern distribution limit of Spiraea decumbens s. str. is in Breginjski Kot (northwestern Slovenia), where we recorded 49 localities of this eastern-Alpine endemic plant species. We determined two new localities in a new quadrant (9746/4) on riparian rocks of the Nadiža River under Mt. Mija at Kozja Peč, which is currently the southeasternmost point of its entire distribution area. We conducted a phytosociological survey of 26 localities. This endemic occurs in dolomite rock crevices in stands classified within the association Spiraeo-Potentilletum caulescentis. On dolomite screes and torrential fens it is found to dominate on small areas in the successional stages, classified into the provisional association Aquilegio einseleanea-Spiraeetum decumbentis (alliance Petasition paradoxi) and into the new association Spiraeo decumbentis-Seslerietum calcariae (alliance Caricion austroalpinae). These stages are gradually becoming overgrown with thermophilous deciduous trees, and in one of the relevés we found the studied species in an open hop hornbeam stand classified into the association Fraxino orni-Ostryetum. Its populations are vital and unthreatened, except in the two new localities under Mt. Mija, which call for special protection due to their small size and a possibility of being backfilled with gravel. Published in DiRROS: 12.07.2017; Views: 4466; Downloads: 2373

128. Legal basis, standards and criteria for evaluating thermal conditions in forest workAnton Poje, Igor Potočnik, 2008, review article Abstract: In this discourse, the Slovene legal basis for thermal conditions at work, together with three international standards for studying thermal conditions SIST EN ISO 7730 (Thermal comfort), SIST EN 27243 (hot environments) and SIST EN ISO 11079 (cold environments), are presented. All three international standards list the criteria for evaluation of thermal conditions and represent the scientific research basis for studying work in practice. For efficient work safety, knowledge of the national legislation is implicit. Keywords: international standards, working conditions, thermal conditions, legislation Published in DiRROS: 12.07.2017; Views: 4565; Downloads: 1886

129. Launching work orders into production of wood enterprise with the multi-criteria decision-making methodLeon Oblak, Boštjan Novak, Igor Lipušček, Jože Kropivšek, 2007, review article Abstract: Quality information is crucial for planning and running of production in wood industry companies. Information of crucial importance is the following: quality in the production process according to work orders and types of product, the information on the missing materials i.e. constituent parts according to projects i.e. work orders and the information on launching work orders into production. The method of multi-criteria decision-making was used for determining the order of launching group products into production. We studied three main criteria: market factors, organisation-production factors and economic factors. For computer support, we chose the computer programme DEXi, which represents the framework of the expert system for multi-criteria decision-making. Keywords: wood enterprise, work orders, organization, multi-criteria decision-making method Published in DiRROS: 12.07.2017; Views: 4469; Downloads: 1949

130. Sedanje stanje gozdnih cest kot rezultat preteklega gospodarjenjaBoštjan Hribernik, Igor Potočnik, 2006, original scientific article Abstract: Gozdne ceste so namenjene zlasti gospodarjenju z gozdom, in prav temu je prilagojeno načrtovanje njihove rabe in vzdrževanja. Naraščanje pomena negozdarskih rab gozdnih cest vodi k višanju standarda vzdrževanja in posledično k trajnemu pomanjkanju sredstev. Višji stroški vzdrževanja nastajajo tudi zaradi pretekle graditve gozdnih cest, ki je na račun hitrega odpiranja kmetij in zaselkov zanemarjala kakovost graditve. V strukturi stroškov vzdrževalnih del zato redno nastopajo stroški ukrepov, ki predstavljajo dokončanje graditve. Rezultat pretekle gradnje, rabe in vzdrževanja je sedanje stanje gozdnih cest, ki je bilo ugotovljeno s popisom poškodb na vzorčnih hektometrskih odsekih. Poleg poškodb spodnjega in zgornjega ustroja ceste zbuja pozornost nizka stopnja dograjenosti sistema odvodnjavanja.
