Opis: Umetna inteligenca, ki strojno posnema človekove kognitivne aktivnosti, kot so reševanje problemov, učenje, razmišljanje in odločanje, se je pojavila kot transformativna tehnologija in že preoblikuje industrije, gospodarstva ter družbe in tako nepovratno spreminja naš način življenja. Na izreden odziv najširše množice uporabnikov je naletela predvsem generativna umetna inteligenca, ki si prizadeva posnemati širok razpon in zapletenost človeških miselnih sposobnosti, s čimer omogoča strojem, da izvajajo različne intelektualne naloge na ravni človeka, le da je pri tem neprimerno hitrejša, se ne utrudi ali naveliča izvajanja nalog, na voljo pa ima praktično neskončen nabor podatkov in informacij. S svojo sposobnostjo ustvarjanja besedila, slike, zvoka ali videa, ki posnemajo človekovo ustvarjalnost, predstavlja tehnologijo z izrednim potencialom za spremembe uveljavljenih načinov učenja in poučevanja. A čeprav v splošnem ponuja številne priložnosti za inovacije in izboljšave v izobraževanju, je hkrati zelo pomembno, da se zavedamo tudi izzivov, ki jih prinaša, ter si prizadevamo za odgovorno in etično uporabo te tehnologije. V poglavju zato predstavimo pregled obstoječih pristopov k urejanju uporabe umetne inteligence v različnih državah po svetu ter ponudimo splošno ogrodje generativne umetne inteligence v izobraževanju, pri čemer navedemo poglavitne razloge in možnosti za njeno ureditev ter regulacijo
Ključne besede: generativna umetna inteligenca, izobraževanje, regulativni okvir, predlagano ogrodje umetne inteligence v izobraževanju

Opis: In the context of climate change, aligning residential building practices with environmental priorities is increasingly important. Wood products, with their lower carbon footprint compared to most alternatives, present a viable solution for more sustainable construction. However, consumer awareness of these benefits remains limited. While interest in sustainability is rising, many consumers still perceive wooden structures as less durable, more vulnerable to fire and earthquakes, harder to insulate, and more expensive to maintain. Additionally, environmental considerations often rank below cost, design, and durability when selecting materials for construction, furnishing, and renovations. To explore these perceptions, we conducted a quantitative survey in 2023 involving 1,009 participants from a representative marketing panel in Slovenia. The study assesses Slovenian consumers’ environmental identity, climate concerns, and the frequency of eco-friendly choices, while examining the importance of sustainability relative to other factors in home design decisions. We further analyse the prevalence of wood-based materials in Slovenian households and gather insights on attitudes toward wood in construction. Our findings highlight the need for targeted communication campaigns to address consumer misperceptions about wood’s durability and environmental benefits, drawing comparisons with past studies from other countries. This research provides actionable recommendations for policymakers and industry stakeholders to enhance consumer engagement and support the adoption of wood as a sustainable building material.

Opis: In this review, we provide an overview of how atomic force microscopy (AFM) measurements on wood or other plant fibers help us understand the structure–property relationship in growing plants, matured wood material, and wood modifications and aging. We selected wood as a model material that can represent a number of lignocellulosic systems and attempted to address the structure–property relationship, as studied in situ. We selected AFM because it allows scientists to study materials in an unaltered, in situ form and relate chemical composition to material properties at a nanoscale level. We summarized the high-resolution measurements of wood cell walls such as topography, adhesion force, modulus, and chemical functional groups using AFM. Our three focus areas were: (1) how the cell wall develops its structure and property in living trees; (2) how the ultrastructure determines cell wall property; and (3) how the modification/aging of the cell wall changes its property in application scenarios.

Opis: This review offers an intensive exploration of the compatibility between flax fibre and cementitious materials, including the kinetics of alkaline degradation of flax fibre, and the interaction between fibre leaching/degradation and cement hydration. This paper also focuses on in-depth insights into the formation and ageing mechanisms of the interfacial transition zone between flax fibre and the cementitious matrix, and in turn how the ageing mechanisms affect the mechanical properties and long-term durability of flax fibre/textile reinforced cementitious composites. A systematic literature review reveals that flax fibre offers superior alkaline resistance compared to other lignocellulosic fibres due to its high crystalline cellulose and low lignin content. While the rough surface of flax fibre enhances bonding with the cementitious matrix, its hydrophilic nature can increase porosity at the interfacial transition zone and promote fibre mineralisation due to fibre swelling and shrinkage. Flax fibre reinforced cementitious composites show comparable flexural and compressive properties to those reinforced with other fibres, while flax textile excels in improving ductility over other textiles and steel reinforcements. Additionally, flax fibre degrades at higher temperatures than sisal and jute fibres. Despite growing interest in flax fibre/textile reinforcement for cementitious composites, key gaps remain in understanding the kinetic mineralisation process of flax fibre, the effects of the alkaline environment and hydration heat on its degradation, and the impact of its alkaline degradation products on cement hydration. Further research is needed to develop direct pull-out testing methods, explore the thermal/fire behaviour of composite phases encompassing the polymeric coating, and create a sustainability framework that considers ecological impacts, recyclability, and waste management for natural fibre reinforced cementitious composites.

Opis: Razvoja kompetenc 21. stoletja pri šolajočih predstavlja enega izmed pomembnih ciljev sodobnega izobraževanja. Kako ta cilj doseči s pomočjo smiselne rabe sodobne digitalne tehnologije, še posebej generativne umetne inteligence (GUI), je za raziskovalce in izobraževalce velik izziv. Tako kot pri vseh večjih tehnično-tehnoloških izumih in industrijskih revolucijah tudi pri razvoju GUI pričakujemo velike spremembe v družbi ter posledično v šoli (trg dela, ekonomija, etični izzivi itn.). Enostavna dostopnost tovrstne tehnologije izrazito vpliva na spremembe v celotni družbi in posledično tudi v šoli, kot smo to lahko opazili pri razvoju družbenih omrežij. Uporaba GUI in ostalih sodobnih digitalnih tehnologij v sodobni šoli mora biti zato pedagoško osmišljena. Potreben je premislek o filozofskih in pedagoško-psiholoških temeljih uvajanja tovrstnih tehnologij v proces poučevanja in učenja, da bo uporaba pedagoško osmišljena in da bo tehnologija v podporo didaktičnim pristopom poučevanja. Generativna umetna inteligenca v šoli ne predstavlja zgolj tehnološkega orodja, temveč transformativni dejavnik, ki lahko izboljša kakovost poučevanja in učenja. V članku so predstavljeni temeljni premisleki za uvajanje tovrstne tehnologije v šolski prostor.
