Raba lesa, tržne količine in projekcije potencialov okroglega lesa listavcev v Sloveniji
Špela Ščap, Matevž Triplat, 2023, original scientific article

Abstract: Gozdarstvo in lesnopredelovalna industrija sta za Slovenijo strateško pomembni gospodarski panogi, ki v zadnjih letih krepita svojo vlogo v biogospodarstvu. Raziskava se osredotoča na problematiko rabe lesa listavcev v Sloveniji. Za akterje, ki se ukvarjajo z rabo lesa listavcev, je pomembno vedenje o razpoložljivi količini domačega lesa, ki se lahko ponudi na trgu. V raziskavi je bila nadgrajena leta 2014 razvita metodologija za oceno količin in potencialov lesa listavcev. Za prihodnje odločanje o razvoju gozdarskega in lesnopredelovalnega sektorja je potrebno tudi raziskovanje tokov lesa, zato je bila v raziskavi opravljena anketa med večjimi predelovalci okroglega lesa listavcev. Ocenjeni teoretični tržni potencial hlodovine listavcev v slovenskih gozdovih je v letu 2021 znašal 0,777 mio m³ in 2,372 mio m³ ocenjeni teoretični tržni potencial lesa slabše kakovosti. Ocenjeni dejanski tržni potencial hlodovine listavcev je v letu 2022 znašal 0,528 mio m³, lesa slabše kakovosti pa 0,741 mio m³. Projekcije potencialov hlodovine listavcev kažejo, da bodo v letu 2025 na trgu podobne količine lesa kot leta 2022. Poraba okroglega lesa listavcev je v letu 2021 znašala 1,433 mio m³, od tega je bilo 0,906 mio m³ lesa predelanega za energetske namene, ostalih 0,527 mio m³ pa v industriji. Rezultati raziskave potrjujejo problematiko rabe lesa listavcev v Sloveniji in nakazujejo priložnosti slovenskega gozdno-lesnega sektorja za prihodnji razvoj.Forestry and wood processing are strategically important industries for Slovenia and have been strengthening their role in the bioeconomy. The study addresses the use of hardwood timber in Slovenia. For actors involved in the use of hardwood timber, it is important to know the available volume of domestic timber that affects the market. For this reason, the survey presented in this work builds on the methodology for estimating the volumes and potentials of hardwood timber developed in 2014. For future decision-making on the development of the forestry and wood-processing sector, it is also essential to analyse wood flows carried out among the major wood processors of round hardwood timber. The estimated theoretical market potential for lower-quality hardwood in Slovenian forests in 2021 was 2.372 million m³, and the estimated theoretical market potential for logs was 0.777 million m³. The estimated real market potential for lower-quality hardwood in 2022 was 0.741 million m³, and for hardwood logs 0.528 million m³. Projections of hardwood potential show that similar volumes of wood will be on the market in 2025 as in 2022. The consumption of round hardwood in 2021 was 1.433 million m³, of which 0.906 million m³ was processed for energy purposes, and the remaining 0.527 million m³ was used in industry. The survey results confirm the concerns about hardwood wood use in Slovenia and indicate opportunities for the future development of the Slovenian forest and wood sector.

Does cognitive training improve mobility, enhance cognition, and promote neural activation?
Uroš Marušič, Joe Verghese, Jeannette R. Mahoney, 2022, original scientific article

Abstract: A close inter-relationship between mobility and cognition is reported in older adults, with improvements in gait performance noticeable after cognitive remediation in frail individuals. The aim of this study was to evaluate the efficacy of computerized cognitive training (CCT) on mobility in healthy, independently living older adults, and to determine whether CCT is associated with changes in neural activation for mobility-related brain processes. Using a randomized single-blind control design, sixty-three non-demented adults age 60 y and older (mean age = 67 y; 76% female, mean Montreal Cognitive Assessment [MoCA] score = 27) were recruited from a local Senior Activity Center. Participants were randomly assigned to either a 2-month CCT program (8 weeks, 3x/week, 40 min/session) or a wait-list control group. Primary outcome was self-selected gait speed during single- and dual-task walking. Secondary outcome was executive function on Trail Making Test (TMT), Part B. Neural activity was assessed via electroencephalography/event-related potentials (EEG/ERPs) targeting lower-limb performance. Results from a linear mixed effect model, adjusted for baseline MoCA score, age, gender, and study completion revealed that compared to controls, CCT improved gait speed during the dual-task (p = 0.008) but not during the single-task walking condition (p = 0.057). CCT also improved executive function (p = 0.024). Further, shorter foot reaction time responses (p = 0.019) were found with enhanced neural activation over sensorimotor areas, with shorter ERP latencies during the P2 component (p = 0.008) and enhanced motor responses (p = 0.009) also evident in the CCT group after the intervention. Overall, the electrophysiological findings suggest possible neural adaptations that could explain improvements in mobility and executive functions associated with CCT in healthy older adults.
