전경린의 「메리고라운드 서커스 여인」 서사 분석 -환상(fantasy)과 모사(mimesis)의 결합서사를 통한 역설적 현실인식을 중심으로
김병로 ( Byoung Ro Kim ) 한국문학이론과 비평학회 2001 한국문학이론과 비평 Vol.12 No.-
I tried to research the meaning of the text as well as the peculiar discourse as a combination narrative of fantasy and mimesis which described in “The Lady of Merry-go-round circus”. My research shows Jeon Kyoung-Lin, the novelist, upholds the traditional realism,the restoration of subjectivity - self, as a rule of discourse. However,Jeon’s text not only has something to do with the above traditional tendency in its inside but its outer related to somewhere anti-traditional realism composed of fantastic discourse factors in the opposite direction, The text of The Lady of Merry -go -round circus tells us the sporadic of post-modernism, the anonymous self’ and the loss of identi-ty scrupulously through the diff rance-situation of textual meaning.

In this study, the vegetation of Pinus densiflora S. et Z., Pinus regida Miller, Pinus koraiensis S. et Z., and Larix kaempferi Satgent (major conifers) stands planted in the Chungcheong-province was investigated to obtain the fundamental informations for the improvement of coniferous barks utilization. The results may be summarized as follows; 1) Barks are much richer in. quantity of extractives and lignin than the corresponding wood. Alcohol-benzene extractives of Pinus koraiensis barks are the highest among others. Pentosan contents are lower in the bark than in the wood, but pentosan contents of the Larix kaempferi bark is the highest among others. 2) Barks are acid in nature, and PH values of barks varying from 3.5 to 4.1 are lower than that of wood. The ash contents of barks are greater than the corresponding wood. 3) A bark comprises from 13.9 to 19.8 percents of a typical log by volume. The calorific values are higher in the barks than in the wood, and calorific values of Pinus koraiensis barks are the highest among others.
저급목재의 자기가수분해 전처리에 의한 고순도 셀룰로오스 기질의 제조
조남석,김병로,백기현 한국목재공학회 2002 목재공학 Vol.30 No.4
본 연구는 자기가수분해전처리를 통하여 반응성이 높은 고순도 셀룰로오스기질을 제조하기 위하여 수행되었다. 공시재의 일반 화학조성은 일본잎갈나무와 신갈나무간에 큰 차이가 있음을 알 수 있었다. 추출물함량은 일본잎갈나무가 신갈나무보다 상당량 많았다. 특히 냉·온수 추출물함량은 2.5∼3.5배 많았다. 이러한 추출물함량의 큰 차이는 일본잎갈나무에는 arabinogalactan이 많이 함유되어 있기 때문인 것으로 사료된다. 리그닌함량은 신갈나무가 잎갈나무보다 5% 정도 낮았으며, 그 대신 홀로셀룰로오스 및 펜토산함량이 각각 3% 정도 높은 값으로 나타났다. 22 ㎏/㎠ 수증기압력에서 5∼60분간의 자기가수분해 전처리과정에서 glucose 함량에는 변화가 없었으나, hemicellulose 및 lignin 함량은 급격한 변화를 보였다. 전처리과정에서 가수분해물의 pH는 3까지 저하되었으며, 이러한 경향은 신갈나무 및 일본잎갈나무에서 동일하게 나타났다. Sodium chlorite 및 sulfite 혹은 bisulfite 전처리 후 자기가수분해가 리그닌함량이 낮은 고순도셀룰로오스기질의 제조에 효과적이었다. 특히 자기가수분해처리재를 알칼리 및 산소-알칼리 2단처리함으로서 0∼0.2%의 리그닌함량을 가지는 고순도기질을 제조할 수 있었다. This study was performed to produce the high reactive lignin zero substrates from autohydrolyzed wood resources. In chemical compositions of used raw-materials, there were significant differences between two species, Japanese larch (Larix leptolepis) and oak (Quercus mongolica) woods. Japanese larch contained 2.5 to 3.5 times higher amounts of extractives than oak wood, which is mainly derived from high content of arabinogalactan in Japanese larch wood. Oak wood has 5% lower lignin content and 3% higher holocellulose and pentosans than larch wood. Concerned to changes in wood components during autohydrolysis pretreatment at 22 ㎏/㎠ steaming pressure for 5∼60 min, glucose content was constant during pretreatment, while hemicellulose and lignin were abruptly changed. Hemicellulose fraction was decreased significantly and lignin contents increased because of its condensation reaction with hemicellulose degradation products. The pH of hydrolyzates during pretreatment was decreased, reached upto pH 3 and since then leveled off. In the case of oak wood, same tendency was observed as in Japanese larch. Autohydrolysis followed by sodium chlorite and sulfite or bisulfite pretreatment was very effective in delignification of the substrates. In particular, two-stage delignification of autohydrolyzed woods with alkali and O_2-alkali resulted in very low lignin content substrates, such as 0∼0.2% lignin substrate.
