이 글의 목적은 박경리 『토지』에 나타난 유교 담론을 연구하는 것이다. 작품에 나타난 유학자들의 담론 양상은 크게 세 가지로 분류할 수 있다. 첫 번째 유학 담론은 외세의 부당한 개입에 맞서 물리적 대결을 해야 한다는 주장이다. 작품에 나타난 가장 대표적 인물은 김 훈장이다. 『토지』는 김 훈장을 통해 일제에 대해 물리적 대결을 하려는 당대 유학자들의 진정성을 인정하면서도, 그 한계를 비판하고 있다. 두 번째 유학 담론은 현실의 부정성을 비판하면서 맞서 싸우지 않고 도피해야 한다는 주장이다. 유학의 도(道)를 미래에까지 계승하기 위해서는 의미없는 죽음보다는 비겁하지만 목숨을 부지하는 것이 더 중요하다고 생각했기 때문이다. 세 번째 유학 담론은 시류에 편승해야 한다는 주장이다. 그들은 자신들의 기득권을 바탕으로 시류에 편승하여 엘리트로서의 역사적 과제를 무시하고 사적 이익을 취하였다. 조준구로 대표되는 이 유형의 인물들은 『토지』에서 가장 크게 비판을 받는다.

Curing behavior and structural property of an inorganic compound added urea-formaldehyde(UF) and urea-melamine-formaldehyde(UMF) were studied. In addition, tensile strength and formaldehyde emission of plywoods made of those resin binders were studied. Curing temperature and structure were not changed, but tensile strengths of plywoods manufactured both with a UF resin and a UMF resin were decreased slightly as increased amount of inorganic compound. Formaldehyde emissions from plywoods were reduced as increased amount of inorganic compound. Wheat flour as an extender was helped to reduce of formaldehyde emission. From the result of this study it might be estimated that using appropriate amount of inorganic compound and proper resin system can be strengthened bond strength and reduced formaldehyde emission.

The influence of adding urea to phenol-formaldehyde (PF) resins as a co-polymer component were investigated aiming at synthesizing useful phenol-urea-formaldehyde resins. Urea was added at 10% by total resin weight. Several methods for the addition of urea to the PF resins during synthesizing resins to see the co-polymerization occurs between urea and PF resins. The urea was added at the beginning, at three different middle stages, and at the end of PF resin synthesis. The copolymerized methylene bridges between phenol and urea molecules were not observed by 13C-NMR; no signal around 50ppm. The curing of urea-modified PF resins, evaluated by dynamic mechanical analysis(DMA), showed some differences among the resins. DMA gel times ranged from 2.75 min to 3.25 min and the resins made with earlier urea additions showed slightly shorter gel times. The longest cure time and gelation time was observed for the resin PFU. Catalyst effects on the DMA cure time values of resins were not significant with different amounts of catalyst or different types of catalyst for all resins tested. Gel times of urea-modified PF resins shortened the most by triacetin catalyst
