Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by decreased acetylcholine (ACh) levels due to elevated acetylcholinesterase (AChE) activity. This shows the need for effective AChE inhibitors such as Cinnamon bark (Cinnamomum burmannii), which contains bioactive compounds with antioxidant and neuroprotective potential. Therefore, this study aimed to evaluate the phenolic, flavonoid, and tannin contents, alongside antioxidant capacity and AChE inhibitory activity of ethanol extract of cinnamon bark as a candi...

Applicability of National Design Specification (NDS)-based 1-h Structural Fire Design to Korean Larch Glue-Laminated Beams: An Experimental Study
Sanghyun YOU , Kyung-Sun AHN , Jung-Kwon OH
J. Korean Wood Sci. Technol. 2026;54(5):551-562.
https://doi.org/10.5658/WOOD.2026.54.5.551
This study evaluated the applicability of a 1-h structural fire design for glue-laminated timber (GLT) beams made of Korean larch using the methodology of the National Design Specification. The primary distinction between current South Korean industrial standards and the approach adopted in this study lies in the application of design stress adjustment factors and the zero-strength layer concept. To validate this methodology, the structural integrity of homogeneous GLT beams was evaluated through load-bearing fire resistance tests under three-s...

Significant financial losses from subterranean termite infestations necessitate the development of effective, environmentally friendly control methods. In this study, we investigated the anti-termite bioactivity of Pucung (Pangium edule) seed extracts against subterranean termites Coptotermes curvignathus. Extracts were prepared via multilevel maceration with n-hexane, ethyl acetate, methanol, and water solvents of varying polarities. Bioactivity was assessed using a 7-day no-choice bioassay. Test specimens were placed on plastic nets inside tu...

J. Korean Wood Sci. Technol. 2026;54(5):582-597.
https://doi.org/10.5658/WOOD.2026.54.5.582
This study aims to optimise milling process parameters for wood-plastic composites manufactured from virgin and recycled polypropylene (v-PP and r-PP) reinforced with teak wood. The investigated parameters were spindle speed, feed rate, and depth of cut. Specimens were produced by injection moulding, and surface roughness was measured in accordance with ASTM D7127. The mean peak-to-valley height (Rz) was used to characterise the surface quality of the specimens. Response surface methodology based on a Box-Behnken design was employed with 15 exp...

https://doi.org/10.5658/WOOD.2026.54.5.598
Teak breeding programs in Indonesia have produced fast-growing varieties, such as Perhutani’s superior teak (Jati Plus Perhutani, JPP), which exhibit greater diameter growth than conventional seed-derived teak. Despite the potential, the wood quality of JPP is often questioned and considered inferior to the slower-growing conventional teak. Therefore, this study aims to evaluate macroscopic anatomical characteristics, wood color (CIELAB), and physical properties of JPP and conventional teak across 4 age classes (5, 12, 15, and 20). Samples we...

Impact Strength and Morphological Properties of Plant-Derived Polylactic Acid/Polyamide 1010 Biocomposites Prepared Using Fused Deposition Modeling 3D Printing: Effect of Printing Speed and Raster Angle
Jong-In PARK , Birm-June KIM
J. Korean Wood Sci. Technol. 2026;54(5):619-630.
https://doi.org/10.5658/WOOD.2026.54.5.619
In this study, the effects of printing speed and raster angle on the impact strength and morphological properties of plant-derived polylactic acid (PLA)/polyamide 1010 (PA1010) biocomposites fabricated via fused deposition modeling three-dimensional (3D) printing were investigated. PLA and PA1010 were first melt-compounded using a twin-screw extruder, followed by filament fabrication using a single-screw extruder. The resulting biocomposite filaments were then 3D-printed at various printing speeds (45 mm/s, 110 mm/s) and raster angles (0°, 45...

https://doi.org/10.5658/WOOD.2026.54.5.631
Fast-growing tropical woods such as jabon (Neolamarckia cadamba) have low density, high porosity, and poor dimensional and thermal stability, which limit their use in high-value applications. In this study, jabon wood was modified by impregnation with a SiO2/boron nitride (BN) nanocomposite (NCP) to improve its physical and thermal properties. SiO2 nanoparticles (NP) were synthesized from betung bamboo leaves using a sol–gel method, whereas BN NP were prepared by microwave irradiation. The SiO2/BN NCP was synthesized using a solvothermal proc...

J. Korean Wood Sci. Technol. 2026;54(5):664-678.
https://doi.org/10.5658/WOOD.2026.54.5.664
Wood plays an important role in human life as a raw material for the furniture and construction industries. However, the declining availability of commercial wood has increased interest in alternative materials, including Betung bamboo (Dendrocalamus asper), to produce laminated bamboo. Due to the susceptibility of bamboo to biological organisms, such as fungi, heat modification and finish coatings are necessary to improve its quality. Heat modification affects the chemical composition and structural characteristics, which influences the physic...

J. Korean Wood Sci. Technol. 2026;54(5):679-693.
https://doi.org/10.5658/WOOD.2026.54.5.679
Wood packaging material (WPM) is a major pathway for the international movement of quarantine pests, and the International Standard for Phytosanitary Measures No. 15 (ISPM 15) regulates its treatment and marking. This study compared WPM quarantine non-compliance between Korea and the United States to clarify how trade structure and geography shape border biosecurity risk. We analyzed 3,924 non-compliance records (2010–2026) from the Animal and Plant Quarantine Agency of Korea and 7,822 records (2020–2025) from the United States Department o...
