About Journal of the Korean Wood Science and Technology

The Journal of the Korean Wood Science and Technology (JKWST), launched in 1973 as the official publication of the Korean Society of Wood Science and Technology, has been serving as a core source of knowledge covering basic and applied research in all areas of wood science and technology. The scope of the journal includes wood anatomy, wood deterioration and preservation, wood physics and engineering, wood chemistry and chemical processing, microbiology, wood processing and composites, furniture and construction, wood industry and business, and wood culture and education (see more specific topics below). Research on non-wood forest products (e.g., mushrooms, bark, fruits, seeds, leaves, roots, and medicinal plants) and non-woody plants (e.g., palm, bamboo, and industrial crops) as a source of fiber, chemicals, and products that can substitute for wood-based materials are also welcome. The journal is published bimonthly, with six issues per year. Supplemental or special issues are published occasionally

Barrel-making commonly involves wood toasting processes that improve the sensory profile of alcoholic beverages. This study aimed to determine the effect of toasting levels on the wood chemical components of Eucalyptus camaldulensis Dehnh., known as river red gum (RRG) using TAPPI and ASTM methods. Total phenolic and sugar contents and volatile components of this wood aged in a model spirit solution were measured using UV-Vis spectrophotometry and gas chromatography-mass spectrometry (GC-MS), respectively. Results showed that heavy toasting sig...

J. Korean Wood Sci. Technol. 2026;54(1):19-35.
https://doi.org/10.5658/WOOD.2026.54.1.19

This study evaluated the density performance of eco-friendly hollow concrete blocks incorporating wood sawdust as a partial replacement for sand, using four mix ratios (1:2:0.3, 1:1.5:0.4, 1:1:0.5, and 1:0.5:0.7) and replacement levels of 0%, 5%, 10%, and 15% by weight. Blocks (150 × 225 × 450 mm) were fabricated with Ordinary Portland Cement, river sand, and sieved sawdust (≤ 2 mm), cured for 28 days, and tested in accordance with ASTM standards. Results showed that dry density decreased significantly (p < 0.05) with increasing sawdust...

Drying Right: A Study of Global Wood Seasoning Methods by Species with Recommendations for Nepal’s Forest Products Sector

Binita SILWAL, Poonam PANT, Sudip PANDEY

J. Korean Wood Sci. Technol. 2026;54(1):36-62.
https://doi.org/10.5658/WOOD.2026.54.1.36

Wood seasoning is a critical step in timber processing that directly affects the durability, strength, and dimensional stability of wood products. This study reviews global wood seasoning practices, focusing on how methods vary based on species-specific properties such as density, fiber structure, moisture content and shrinkage rates. Common techniques like air drying, kiln drying, and advanced methods (vacuum, steam, hybrid) are compared for their effectiveness across both hardwood and softwood species. The research highlights the importance o...

Eco-Friendly Solution Using Wood Vinegar from the Lesser-Known Wood Santiria griffithii from West Kalimantan to Control Termites Coptotermes curvignathus and Schizophyllum commune Fungus

Alkhadi ALKHADI, Hasan Ashari ORAMAHI, Hera DESVITA, Farah DIBA, Hikma YANTI, Marwanto MARWANTO

J. Korean Wood Sci. Technol. 2026;54(1):63-80.
https://doi.org/10.5658/WOOD.2026.54.1.63

Lesser-known wood refers to wood of lower quality that requires additional processing to improve its value. One way to achieve this is to convert wood into other products such as wood vinegar, which can be produced from wood waste. This study aims to assess the effectiveness of wood vinegar derived from Santiria griffithii wood in controlling damage caused by Coptotermes curvignathus termites and Schizophyllum commune fungi on wood. In this study, S. griffithii wood was pyrolyzed at 300°C, 350°C, and 400°C. The application of wood vinegar to...

Antifungal Potential of Methyl Jasmonate-Induced Liquidambar excelsa Balsam Exudate Fractions against the Wood Decay Fungus Schizophyllum commune

Anne CAROLINA, Muhamad RIZQI, Trisna PRIADI, Eva RACHMAWATI, Resti MEILANI, Dai KUSUMOTO, Rita Kartika SARI

J. Korean Wood Sci. Technol. 2026;54(1):81-93.
https://doi.org/10.5658/WOOD.2026.54.1.81

In this study, we investigated the induction, chemical composition, and antifungal activity of balsam exudates secreted from Liquidambar excelsa. Exudation was stimulated with 10% (v/v) methyl jasmonate, and the collected balsam was separately extracted with ethanol and n-hexane and distilled to obtain the hydrosol and essential oil fractions. Solvent extraction yielded 63.86% ethanol extract and 63.55% n-hexane extract, whereas distillation yielded 19.05% essential oil, accompanied by hydrosol as a co-product. Gas chromatography–mass spectro...

Repurposing Senescent Oil Palm Trunks into Sustainable Plywood: A Green Alternative to Conventional Disposal Practices

Natworapol RACHSIRIWATCHARABUL, Panya DANGWILAILUX, Wachara KALASEE, Chaowat AUTTHANIT, Putipong LAKACHAIWORAKUN

J. Korean Wood Sci. Technol. 2026;54(1):94-109.
https://doi.org/10.5658/WOOD.2026.54.1.94

This study evaluates the mechanical performance and carbon emission implications of producing plywood from senescent oil palm trunks (OPT), a readily available agricultural residue in Thailand. Veneers were dried using hot air at 90°C and a hybrid hot air–microwave process before being fabricated into plywood with urea–formaldehyde adhesive. Mechanical tests showed that plywood from hybrid-dried veneers (OPP-H90-M2k) achieved higher tensile strength and modulus of rupture (MOR) than hot-air drying alone (OPP-H90), while bondline shear st...

Wissanee YINGPRASERT, Suparat PEAKLIN

J. Korean Wood Sci. Technol. 2026;54(1):110-128.
https://doi.org/10.5658/WOOD.2026.54.1.110

This study evaluated the feasibility of using Acacia mangium bark extract (BE) as a bio-based, formaldehyde-free adhesive for rubberwood particleboard, focusing on the effects of two catalysts: sodium hydroxide (alkaline) and boric acid (acidic). Gel time, viscosity, thermal behavior, mechanical performance, and formaldehyde emissions were assessed. The uncatalyzed BE adhesive showed a gel time of 29.59 min, which decreased to 6.44 min with sodium hydroxide (BE–NaOH adhesive) and 4.22 min with boric acid (BE–Boric adhesive), highlighting th...
