About Journal of the Korean Wood Science and Technology

The Journal of the Korean Wood Science and Technology (JKWST) launched in 1973 as an official publication of the Korean Society of Wood Science and Technology has been served as a core of knowledges on wood science and technology. The Journal acts as a medium for the exchange of research in the area of science and technology related to wood, and publishes results on the biology, chemistry, physics and technology of wood and wood-based products. Research results about applied sciences of wood-based materials are also welcome. The Journal is published bimonthly, and printing six issues per year. Supplemental or special issues are published occasionally.

This study aimed to investigate the bending and thermal properties of lightweight engineered wood produced from sugarcane bagasse and coir fiber as reinforcement, with a mixture of tapioca starch (TPS) and polyvinyl acetate (PVAc) as the matrix. Sugarcane bagasse and coir fibers were prepared with varying weight ratios (30:70, 70:30, and 50:50) and subsequently incorporated into the TPS/PVAc matrix via a molding technique, thus forming the lightweight engineered wood. The bending and thermal properties of the lightweight engineered wood were ev...

Products derived from lignocellulose are susceptible to substantial damage from termites. We aimed to evaluate the durability of particleboard treated with wood vinegar, adhesive, and a combination of raw materials for particleboard production. Specifically, we examined the effects of adhesive concentration (X1), wood vinegar concentration (X2), and a combination of oil palm trunks and sengon wood sawdust (X3) on the treatment process. The optimal treatment conditions were predicted using response surface methodology with a three-factor inscrib...

https://doi.org/10.5658/WOOD.2025.53.1.33

This study aims to determine the influence of density, temperature, humidity, and processing time in ultrasonic and pulsed magnetic fields on the wood of natural and stained oak on the magnitude of their internal friction. The logarithmic decrement of damping, obtained by free flexural vibrations, was used to assess the magnitude of internal friction. As a result of the performed research, it was established that the most significant influence on the increase in the logarithmic decrement magnitude of natural oak is exerted by ultrasonic treatme...

https://doi.org/10.5658/WOOD.2025.53.1.49

Sappan wood (Caesalpinia sappan L.) heartwood contains phenolic compounds that require protection during storage due to its susceptibility to light, moisture, and oxygen. This study examines the microencapsulation of sappan wood extract using spray drying with various wall materials: maltodextrin (MD), modified starch (MS), gum arabic (GA), and their mixtures. Seven combinations of wall materials were tested. Spray drying was conducted at an inlet temperature of 150°C and a feed flow rate of 4 mL/min. Microcapsules were evaluated for yield, ...

https://doi.org/10.5658/WOOD.2025.53.1.66

The construction industry has increasingly emphasized the importance of sustainable materials. These sustainable materials offer insights into the development of effective and ecofriendly acoustic materials. This study explored the potential of water hyacinths for sound absorption performance. An impedance tube test was conducted to analyze the sound absorption coefficient. The specimens were fabricated by spraying dried water hyacinth stalks with a polyvinyl alcohol adhesive, allowing them to dry and then cutting them into different thicknesse...

Effect of Licorice Extract on Biofilm Formation in Two Pathogenic Bacteria: Aeromonas hydrophila and Yersinia enterocolitica

Youngseok HAM, Delin XU, Tae-Jong KIM

J. Korean Wood Sci. Technol. 2025;53(1):77-88.
https://doi.org/10.5658/WOOD.2025.53.1.77

Licorice inhibits the biofilm formation ability and cell growth of Streptococcus mutans, which causes dental caries. In this study, we evaluated the effects of licorice extract on biofilm formation and cell growth of Aeromonas hydrophila and Yersinia enterocolitica to understand strain-specific biofilm formation. Extracts prepared in 50% and 20% ethanol caused the maximum inhibition of A. hydrophila and Y. enterocolitica biofilm formation, respectively. Biofilm formation in A. hydrophila was inhibited in a concentration-dependent manner up to 1...

Previous studies have shown that the aqueous extract of Strychnos ligustrina wood exerts antimalarial activity by inhibiting the growth of Plasmodium falciparum strain 3D7. This study determined the extract yields of three different parts of the woody stem of S. ligustrina (heartwood, sapwood, and bark), analyzed their phytochemical profiles using liquid chromatography–tandem mass spectrometry (LC-MS/MS), investigated their antimalarial activity against P. falciparum, and predicted the active compounds using molecular docking studies. The pow...
