이학주,최윤정,가강현,박원철 한국목재공학회 2003 목재공학 Vol.31 No.4
송이(Tricholoma matsutake) 자실체의 메탄올(methanol, MeOH) 추출물로부터 4개의 화합물을 분리하였으며, 기기분석 결과 adcnosinc (9-β-D-ribofuranosyladenine)을 비롯하여, methyl trans-cinnamate, ergosterol (ergosta-5, 7, 22-triene-3β-ol) 및 ergosta-4, 6, 8 (14), 22-tetraen-3-one으로 각각 동정하였다. One alkaloid derivatives, one amide and two steroids were isolated from the fruit bodies of Tricholoma matsutake. The structures were determinded as adenosine, methyl trans-cinnamate, ergosterol and ergosta-4, 6, 8 (14), 22-tetraen-3-one, respectively, on the basis of spectroscopic data.

This project investigated the use of two types of thermoplastic pipes, High-Density Polyethylene (HDPE) and Poly-vinyl Chloride (PVC), as cross-drains under highways. Pipes ranging from 0.3 m (12 in.) to 1.5 m (60 in.) in diameter were evaluated under deep fills, minimum cover, and construction loads. In addition to a comprehensive literature review, an analytical study into the allowable fill heights for thermoplastic pipes and a field study to observe the installation and performance of the pipe in service conditions were conducted. Based on the study findings, recommendations regarding how and when thermoplastic pipe should be installed are provided.

Chaga mushroom (Inonotus obliquus), which has invaluable medicinal uses, grows only on living trees. To date, it is still harvested from its natural habitat and is not cultivated artificially. We artificially cultivated chaga mushrooms by inoculating its sawdust spawns on Betula platyphylla var. japonica in 2007, and monitored mushroom growth on the inoculated trees for 9 years. The mushrooms grew less than 1 cm per year, with the largest mushroom growing up to 9 cm in the 9 years of study. There was no difference in the growth (diameter at breast height) of trees with viable and non-viable I. obliquus. In conclusion, artificial cultivation of chaga mushroom was successful. Our findings suggest that selection of large B. platyphylla var. japonica as host tree could lead to better I. obliquus productivity. Further improvements of the method are needed to increase the success rate of I. obliquus inoculation.
