Study on Biological Distribution to Conserve the Tripitaka Koreana woodblocks in Haeinsa Temple
2015 - IRG/WP 15-10844
Tripitaka Koreana is the Wood-carved Buddhist scriptures which were made in 13th century. And Janggyeong Panjeon that is depository for the Tripitaka Koreana was built in 15th century. In recent days, biological damage becomes a serious problem to wooden cultural heritage including historical wooden buildings with global warming. In this study, termite monitoring on whole Haein-sa temple area and ...

Study on the Effects of Flame Retardant in Dancheong for Korea Wooden Cultural Heritage
2015 - IRG/WP 15-40692
This study identifies the effect of the agent depending on environment change and conducted basic study to prepare criteria for stable application. Dancheong sample, which is similar to wooden cultural heritage, was manufactured to study the effect of the agent on dancheong. Regular observation on the samples located in inland and shoreline area in the country detected visible phenomena. Whitening...

Combustion and thermal characteristics of Korean wood species
2016 - IRG/WP 16-40727
This study examined the combustion and thermal characteristics of domestic woods in Korea. Wood was confirmed by a cone calorimeter according to the KS F ISO 5660-1 standard. The combustion properties of the wood were measured in terms of the heat release rate (HRR), total heat released (THR), mass lose rate (MLR), and ignition time (time to ignition; TTI). Also, the thermal properties were measur...

Controlled deposition of copper nanoparticles using wood inherent architecture as natural template
2017 - IRG/WP 17-40783
As one of the most abundant renewable biomass resources, wood can be used as templates for synthesizing functional nanoparticles with controlled shapes and sizes. In this study, copper nanoparticles were synthesized with controlled shapes and sizes using poplar wood as the natural inexpensive and renewable templates. The crystal structure and morphologies of the copper nanoparticles were character...

Encapsulation of chlorothalonil with polylactic acid using nanoprecipitation method for rubberwood preservation
2018 - IRG/WP 18-30722
Wood is a very beneficial material for humankind. The current trend is employing organic biocides as wood preservatives to inhibit the wood from biodeterioration caused by fungi and termite. However, these organic biocides are facing some shortcomings when being introduced into the wood using conventional water-based treatment due to their poor water solubility. Polylactic acid (PLA) was employed ...

Molecular identification of marine borers causing wood deterioration on marine facilities in Korea
2019 - IRG/WP 19-10955
The deterioration factors of wood which was used in the marine environment, Tongyeong (South Coast) and Incheon (West Coast) in Korea, were investigated in order to develop technologies for safe and long-term use of timber in ocean facilities.
The marine microorganisms isolated by damaged wood were identified as morphological Chelura sp. and Teredo sp. As a result of DNA sequencing, it was confir...

Evaluation of weathering and termite resistance of the Myoung-oil as a Korean traditional coating agent
2022 - IRG/WP 22-10996
This study investigated the applicability of Myoung-oil (MO) as an eco-friendly preservative of Korean wooden cultural properties and buildings. Wood test specimens painted with various concentrations of MO were exposed in the external environment. Then color change and wettability of the wood surface were evaluated and compared depending on the exposure time. As a result of exposure for 12 months...

Evaluation of Decay Resistance of Copper-based Preservatives Treated-Wood exposed to different field test sites in Korea
2022 - IRG/WP 22-20679
In Korea, preservative treated wood is required to have a stamp on the surface which contains information such as wood species, use categories, and the company that treated the wood. Such stamping is necessary to safely and appropriately use the treated wood. Since majority of treated wood is being used outdoor environment, the treated wood must have efficacy against wood decay fungi or termite. I...

Effect of impregnation modification treatment on properties of Paraserianthes falcataria wood
2023 - IRG/WP 23-40966
Modification treatment can improve the properties of wood, particularly those of fast-growing species. Paraserianthes falcataria, also known as batai, is a fast-growing species with low wood density. This species has piqued the interest of those involved in industrial wood processing as a promising alternative for construction. The aim of this study is to improve the dimensional stability of batai...

A new wood preservative system based on basic copper compound nanosols
2024 - IRG/WP 24-20728
A bottom-up process was established to synthesize insoluble basic copper compound nanoparticles and simultaneously form a stable nanosol by dropping a neutralizing agent solution into an aqueous solution of a copper compound to which an appropriate dispersant system was added. The main ingredient of MCA (Micronized Copper Azole), the leading copper-based wood preservative in the current world mark...

Assessment of hydrophobic properties of acetylated and furfurylated Korean wood species
2024 - IRG/WP 24-30812
To increase the utilization of Korean wood species, the hydrophobic properties of the most commonly used wood species in Korea were compared according to wood modification. Pinus densiflora (sapwood and heartwood) and Larix kaempferi (heartwood) were selected as test wood species, and Pinus radiata (sapwood) was selected as the control wood species. The wood modification was performed by acetylati...
