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.

Increasing the use of wood biomass is relevant at all stages of wood harvesting and processing. This is because up to 50% of the tree biomass is unused waste that is incinerated or buried. In this regard, sawmill waste is processed into technological chips for fiberboard production. This article presents the results of a study on fiberboard production with the addition of coniferous wood greenery. The expediency of the heat treatment and extraction of coniferous wood greenery was assessed before grinding to various degrees. Based on the analysi...

The rise in industrial activity and human population has increased fossil fuel consumption. Consequently, Indonesia has promoted a decarbonization program to achieve carbon neutrality or net-zero emissions, including developing renewable energy from biomass. However, comprehensive information on the potential biomass sources for power plants remains limited. To address this, this study investigated the potential of four local shrub species (bungur, Lagerstroemia speciosa; locong, Ganophyllum falcatum; latte, Myrsine avenis; and terasa, Mischoca...

Effect of Keruing and Meranti Wood Extracts on the Nail Corrosion Rate

Andrian FERNANDES, Erwin ERWIN, Arif WAHYUDIANTO, Harlinda KUSPRADINI

J. Korean Wood Sci. Technol. 2024;52(6):555-564.
https://doi.org/10.5658/WOOD.2024.52.6.555

Many houses and wooden constructions in East Kalimantan Province use keruing and meranti wood. Local carpenters widely use ordinary and concrete nails to join the wood. One of the factors affecting the corrosion rate of nails in wood is the extractive compound. Unfortunately, the amounts and types of keruing and meranti wood extractives and their effects on the corrosion rates of ordinary and concrete nails have not been studied. This study aimed to determine the amount and types of keruing and meranti wood extractives and their effects on the ...

Wood has different cell composition and characteristics depending on the wood species, and even though they are the same species, their characteristics can differ depending on the growing area. Therefore, in order to use wood effectively, it is very important to accurately know the characteristics of wood according to the wood species and the appropriate use for it. Tulip trees have been widely planted throughout South Korea since the early 2000s because they grow quickly, have excellent environmental adaptability, and have excellent carbon abs...

https://doi.org/10.5658/WOOD.2024.52.6.573

This study analyzed the distribution and species of termites living in Korea. Eighty-five localities were selected for the study, and subterranean termites were collected from three colonies per locality. The morphological and genetic species analysis of the collected termites revealed three species: Reticulitermes speratus kyushuensis, Reticulitermes kanmonensis, and Reticulitermes speratus speratus. The drywood termite found in Jinhae-gu, Changwon, Gyeongnam, was analyzed as Incisitermes minor. By looking at the temperature of the termites’...

Failure Analysis of Laminated Wooden Arches Strengthened with Novel Carbon-Fiber-Reinforced Polymer (CFRP) Composites: An Experimental Study

Muslum Murat MARAS, Hasan Basri YURTSEVEN, Mehmet Faruk OZDEMIR

J. Korean Wood Sci. Technol. 2024;52(6):585-604.
https://doi.org/10.5658/WOOD.2024.52.6.585

Laminated wood is produced as a single large element by combining pieces of elements. Wooden building materials are used in several old buildings that survive to the present day. To strengthen wooden structures, they must be preserved in accordance with their originality without damaging their historical texture. In this study, an innovative strengthening method was developed by placing carbon-fiber-reinforced polymer (CFRP) fabrics between wooden planks before lamination. With this new strengthening method, CFRP fabrics were placed between the...

Jiyong KIM, Kyung-Sun AHN, Sung-Jun PANG, Da-bin SONG, Chul-Ki KIM, Kwangmo KIM, Kugbo SHIM, Keon-Ho KIM, Jung-Kwon OH

J. Korean Wood Sci. Technol. 2024;52(6):605-617.
https://doi.org/10.5658/WOOD.2024.52.6.605

This study established a standardized test method for the in-plane shear modulus of cross-laminated timber (CLT) KS F 2082. Among the test methods used to evaluate the in-plane shear modulus of CLT, the picture frame method was considered appropriate for achieving a pure shear state. However, the test procedures for the picture frame method have varied among studies owing to the lack of a standardized test method. Therefore, the deformation measurement area and loading protocol are discussed herein. The measurement area was determined based on ...
