“…문 화재청의 조사에 따르면 우리나라 국가 및 시도지정문화 재의 약 25%가 목조건축물로 목재가 차지하는 비중이 높 은 편이다 (Kim, et al, 2019a). 목조문화재는 오랜 세월 동 안 외부 환경에 그대로 노출되어 있어 자외선이나 수분 등의 물리적, 화학적 열화에 의해 손상될 뿐만 아니라, 흰 개미와 같은 목재 가해 해충 및 부후균에 의한 생물학적 열화가 발생하기 쉽다 (Kim, 2007;Kim et al, 2011;Kim et al, 2019b;Seo et al, 2015;Yoon et al, 2020).…”

In this study, we investigated the applicability of a termiticide based on metofluthrin for termite control on traditional wooden buildings. To evaluate their mortality, termites were exposed to the agent, diluted to various concentrations, for seven days; it was found that it had a sufficient insecticidal effect although there was a difference depending on the degree of agent dilution. Next, the effect on Dancheong, used in traditional wooden structures, was measured based on the color change according to the number of agent treatments. The results showed that only the color difference value of two pigments (i.e., Bun and Juhong) was measured as 3.0 or higher. However, there this varied according to the dilution ratio. Thus, it was found that most pigments had little effect on the color of Dancheong. Finally, the termiticidal efficacy of the agent when applied to wood was evaluated. We found that the specimens coated with 10-fold and 20-fold dilutions exhibited 2.83 and 6.28% mass loss, respectively. The 10-fold dilution satisfied the performance of termiticide as a mass loss of less than 3%. In conclusion, the metofluthrin-based agent used in this study has little effect on various Dancheong pigments and has a termiticidal effect against termites; it is therefore suggested that it may be used in preserving traditional wooden cultural properties in Korea.

A lime is a traditional material that has been used for a long time and has been used in ancient tumb, fortress walls, ondol, buildings, and lime-mortar barrier tombs. Based on the literature records used lime with additive materials, in this study, observed changes in the composition of perilla oil according to curing environment, sampling position, and time tor time mixed or applied with perilla oil among traditional lime additive materials by pyrosis gas chromatography mass spectrometery (Py-GC-MS) and Fourier Transform infrared spectroscopy(FT-IR) analysis. For perilla oil, unsaturated fatty acids such as oleic acid, and linoleic acid, saturated fatty acid, palmitic acid were identified as the main component, and as perilla oil was cured, the ratio of saturated fatty acids such as azelaic acid, palmitic acid, and stearic acid tended to increase. This trend has also been confirmed in lime mortars using perilla oil. In limes mixed with perilla oil, oleic acid is predominantly detected. In the case of lime coated with perilla oil, no characteristic component was identified in the internal sample, and a change in characteristic components were confirmed according to the indoor and outdoor environments on the coated surface. Palmitic acid, stearic acid, and oleic acid were detected as main components in a stable indoor environment, but azelaic acid, palmitic acid, and stearic acid were identified as main components as they were exposed to the climate environment(outdoor). In particular, it is characterized by the fact that it was detected only in mortar applied with azelaic acid. However the possibility of grasping perilla oil using FT-IR was expected to have a detection limit depending on the concentration of perilla oil. Such analysis results are expected to contribute to the discovery of lime additive materials used in cultural heritage and the research on construction technology in the future.
