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 research investigates the development of sound-absorbing composites using areca nut shells fibers (ANS) bonded with polyvinyl alcohol glue, aiming to create an environmentally friendly and sustainable alternative to conventional synthetic materials. The research explores the effects of varying thicknesses (10, 20, and 30 mm) and fiber lengths (10, 20, and 30 mm) on the sound absorption performance of the composites. The sound absorption coefficient (SAC) was measured using the impedance tube method to determine the composites’ effectiven...

Influence of Short-Duration Densification on the Temperature Profile of Cross-Laminated Timber during an Open Burning Test

Charles Michael ALBERT, Kang Chiang LIEW

J. Korean Wood Sci. Technol. 2025;53(2):119-128.
https://doi.org/10.5658/WOOD.2025.53.2.119

This study investigated the fire performance of cross-laminated timber (CLT) manufactured from the densified laminas of Paraserianthes falcataria, a fast-growing timber species. The aim of the study was to provide insights into the influence of short-duration densification on the thermal behavior of CLT during open burning, where compression ratios (40%, 50%, 60%) were applied. The outcomes indicated that higher compression ratios resulted in the formation of an insulating char layer that delayed the charring rate and enhanced the fire resistan...

Rattan is a vital organic biomaterial alongside wood and bamboo and is used in furniture, handicrafts, and construction. The industry necessitates a rapid, noninvasive assessment of rattan quality for optimal efficiency. This study aims to identify an optimal prediction model for estimating rattan density using near-infrared (NIR) spectroscopy. The rattan laboratory data included measurements of green and air-dry densities. A prediction model was constructed using NIR spectra obtained from the transverse and bark surfaces. Multivariate data ana...

Analysis of Wood Formation in Red Jabon [Anthocephalus macrophyllus (Roxb.) Havil] Using Pinning Method

Bahidin Laode MPAPA, Imam WAHYUDI, Istie Sekartining RAHAYU, Andi Detti YUNIANTI

J. Korean Wood Sci. Technol. 2025;53(2):138-151.
https://doi.org/10.5658/WOOD.2025.53.2.138

Studies on tropical wood formation using the pinning method in fast-growing species, such as red jabon [Anthocephalus macrophyllus (Roxb.) Havil], remain limited. In this study, we aimed to investigate wood formation over a certain period to determine the effect of climate (rainfall and temperature) on xylem formation. Wood formation in red jabon is understood by examining the anatomical structure of wood and new cell formation after pinning. The anatomical structure was observed from day 30 to 360 days after pinning, with sampling conducted at...

https://doi.org/10.5658/WOOD.2025.53.2.152

One of the most effective ways to use wood-based products in terms of carbon neutrality is as structural materials for wooden buildings. This can enhance the carbon storage effect by extending its service life. To increase wood usage through building expansion, it is essential to implement supportive policies and conduct foundational research on the factors that ensure structural safety and predict building performance. Nail joints are among the most frequently used joints in wooden construction. In Korea, the shear performance of nail joints i...

Wood plastic composites (WPC) were formed with wood waste and recycled polymer matrices to address the environmental concerns from the overuse of plastic materials and natural wood products. This study aimed to examine the mechanical and physical properties of WPC produced from two different types of native Indonesian wood before and after immersion in freshwater and seawater. The effects of employing various polymer matrix types of recycled and virgin polypropylene (r-PP and v-PP) produced through two distinct processes, compression moulding (...

J. Korean Wood Sci. Technol. 2025;53(2):193-206.
https://doi.org/10.5658/WOOD.2025.53.2.193

Cellulose-chitosan-silk fibroin (CCF) composite films were fabricated using a 60% lithium bromide solution, and their physicochemical properties were analyzed. The CCF films exhibited a light yellowish-beige color with high transparency, and no distinct differences were observed in their cross-sectional structures. Throughout the dissolution and regeneration processes, cellulose was converted from cellulose I to cellulose II, with chitosan and silk fibroin (SF) influencing the crystalline structure of the film. High concentrations of cellulose ...
