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.

Nanocomposite Electrode Materials Prepared from Pinus roxburghii and Hematite for Application in Supercapacitors

Dibyashree SHRESTHA

J. Korean Wood Sci. Technol. 2022;50(4):219-236.
https://doi.org/10.5658/WOOD.2022.50.4.219

Wood-based nanocomposite electrode materials were synthesized for application in supercapacitors by mixing nanostructured hematite (Fe2O3) with highly porous activated carbon (AC) produced from the wood-waste of Pinus roxburghii. The AC was characterized using various instrumental techniques and the results showed admirable electrochemical properties, such as high surface area and reasonable porosity. Firstly, AC was tested as an electrode material for supercapacitors and it showed a specific capacitance of 59.02 Fg−1 at a current density of ...

Experimental Study of Bending and Bearing Strength of Parallel Strand Lumber (PSL) from Japanese Larch Veneer Strand

Seichang OH

J. Korean Wood Sci. Technol. 2022;50(4):237-245.
https://doi.org/10.5658/WOOD.2022.50.4.237

This study examined the structural performance of experimental parallel strand lumber (PSL) from a Larch veneer strand. The prototype of PSL from a Larch veneer strand was manufactured in the experimental laboratory and tested. The bending and dowel bearing strength were determined from the modulus of elasticity (MOE), modulus of rupture (MOR), and dowel bearing strength based on a 5% offset yield load. The test results indicated that the average MOR of PSL was higher than that of 2 × 4 dimension lumber, and the average MOE of PSL was lower ...

Tomosynthesis Feasibility Study for Visualization of Interiors of Wood Columns Surrounded with Walls

Jun Jae LEE, Chul-Ki KIM

J. Korean Wood Sci. Technol. 2022;50(4):246-255.
https://doi.org/10.5658/WOOD.2022.50.4.246

The need for non-destructive testing and evaluation of Korean traditional wooden buildings is increasing because of their widespread deterioration. Among all types of deterioration, termite damage in wooden columns is the most difficult to detect with the naked eye because it starts inside the wood, and the initial deterioration is small. X-ray computed tomography (CT) is the best technology to investigate the inner state of wood that has less damage, but applying it to wooden columns between walls is challenging. Therefore, the feasibility of ...

Study of Characterization of Activated Carbon from Coconut Shells on Various Particle Scales as Filler Agent in Composite Materials

Rudi DUNGANI, Sasa Sofyan MUNAWAR, Tati KARLIATI, Jamaludin MALIK, Pingkan ADITIAWATI, SULISTYONO

J. Korean Wood Sci. Technol. 2022;50(4):256-271.
https://doi.org/10.5658/WOOD.2022.50.4.256

Activated carbon (AC) derived from coconut shells (CS-AC) was obtained through pyrolysis at 700°C and subsequently activated with H3PO4. AC was ground in a Wiley mill several times to form powder particles at particle scales of 80, 100, and 200 meshes. The characterization of the AC was studied using scanning electron microscopy (SEM), X-ray diffraction analysis (XRD), Fourier-transform infrared spectroscopy (FT-IR), and surface area analysis (SBET). The CS-AC-200 mesh resulted in a higher percentage of mesopores and surface area. This parti...

Antioxidant Activities of Essential Oils from Citrus × natsudaidai (Yu. Tanaka) Hayata Peels at Different Ripening Stage

Jiyoon YANG, Won-Sil CHOI, Su-Yeon LEE, Minju KIM, Mi-Jin PARK

J. Korean Wood Sci. Technol. 2022;50(4):272-282.
https://doi.org/10.5658/WOOD.2022.50.4.272

The essential oil extracted from Citrus × natsudaidai (Yu. Tanaka) Hayata peels is known to have various biological properties. However, the chemical composition of essential oil is influenced by the ripening stages of fruits, which then affects related biological activities. This study investigates the antioxidant activities of essential oils extracted from Citrus × natsudaidai peels at different ripening stages (immature, mature, and overripe). The essential oils were extracted using the hydro-distillation method. As a result of gas chroma...

Peracetic Acid Treatment as an Effective Method to Protect Wood Discoloration by UV Light

Kyoung-Chan PARK, Byeongho KIM, Hanna PARK, Se-Yeong PARK

J. Korean Wood Sci. Technol. 2022;50(4):283-298.
https://doi.org/10.5658/WOOD.2022.50.4.283

Wood has always been used for various day-to-day applications such as interior or exterior construction materials, and household products. However, it can undergo photodegradation and discoloration by environmental factors including ultraviolet (UV) light, and thus has shortened its service life. Bleaching or delignification of wood surfaces is a suitable solution to stabilize wood against weathering by UV because these techniques can alter or remove the chromophores in lignin, which is a main factor of wood discoloration. To improve the color ...
