名詞化의 語彙的 接近

李明煥 서울産業大學校 1984 논문집 Vol.20 No.1

In the process of nominalization we come into the problem whether nominals are derived transformationally or lexically. Transformationalists depend largely on a great deal of descriptive complexity in order to derive nominals, Therefore language learners should deal with large numbers of related transformations to do it. On the other hand, according to the lexicalist hypothesis language learners have only to learn the differences in the deep structure. Chomsky (1970) says the extension of a lexicon enables the categorial component to be simplified. The difference between the lexicalist and the transformationalist in approaching to nominalization lies in the method of derivation With the properties lying in the base structure lexicalists extend them, establishing D-structure close to S-structure to simplify the transformational component, relating it to the transformation, joining the semantic representation to D-structure through categorial components. The appliation of X-convention to the derivation of nominalization enables the lexicalists to derive nominals directly without violating the basic lexicon. But of-insertion by adjunction satisfies CRP in S-structure, violating the projection principle, which shows N?=P? proving to be contradictory. Among the three solutions suggested by Chomsky(1981) and Stowell(1981), we consider Chomsk's explanation. (45) c, in which a neutralized category charing properties of NP-PP is proposed, is most proper.

李明煥 서울여자대학교 1978 서울여자대학논문집 Vol.- No.7

The purpose of this study is to establish an effective way to utilize the application of Epichlorohydrin polymer compound. The results are shown as follow: 1. For the most effective heat-resisting compound of epichlorohydrin hose and tube either red lead or Dyphos/Dythal family is recommended to be used as acid acceptor, either NBC and Niclate as fire-fighting aid, and ethylene thiourea (NA-22, Thiate N or Pennac CRA) for crosslinking. Imidazol too appears to be the most effective for air aging, and especially the vulcanizer made under sufficient curing time turns out to have excellent heat-resisting effect. For the coulping agent Silane-189 was used, and when silica was charged in, long-range heat-proof quality was far better than that when in black compounding . 2. In long-range heat-proof air aging effect heat-resisting epichloro hydrin polymer compund was superior to CR, CSM or NBR, but in air aging effect was a little inferior heat-proof EPDM. In the meantime, epichlorohydrin only polymer compound shows a higher numerical value in long-range aging test than EPDM. The compound which showed the highest antioxidizing effect was ACM/ECO blend.

Pyrolytic analysis based on pyrolysis-gas chromatography(PGC) technique have been performaed for identification of NR, BR, SBR, CR, EPDM and their blends. The results each of characteristic peak of single rubber showed dipentene, 4-vinylcyclohexene, styrene, chloroprene, 2,4-dimethy1-1-heptene. Since the physicochemical properties of blends of NR/EPDM. BR/EPDM, SBR/EPEM, CR/EPDM,NR/EPDM, BR/SBR/EPDM were heavily affected by their blending ratio, it was found to be essential to confirm the blending ratio of the blends. Finally, the standard calibration curves for characterization of various blending ratio in each system were obtained on the basis of their pyrograms.

마늘외 처리온도 및 시간에 따른 thiosulfinate 함량의 변화와 실온 및 고온추출시 황화합물의 성분 변화를 조사하기 위하여 N-ethylmaleimide 발색반응과 UV Spectrophotometer 및 gas chromatograph를 이용하여 분석한 결과 다음과 같은 결과를 얻었다. 처리온도 및 시간에 따른 thiosulfinate함량의 변화에 있어서 25℃, 50℃에서 5시간, 75℃에서 30분까지 존재하였으나, U.V spectrophotometer에 의한 검출에서는 75℃, 1시간과 100℃, 15분까지도 완전히 분해되지 않으며, 또한 diallyl disulfide의 양도 75℃, 15분보다 1시간에서 3배 정도 많았는데 이는 thiosulfinate가 분해되어 생성된 것으로 앞의 결과를 뒷받침해 주고 있다. 실온에서의 n-hexane 및 수증기 증류하여 얻은 추출물의 함량은 각각 0.10%, 0.12% 였으며 실온의 n-hexane추출물에서는 diallyl disulfide보다는 동정하지 못한 물질이 주물질이었으며 수증기 증류하여 얻은 정유에서는 diallyl disulfide가 주물질로 관찰되었다. The effects of heating time and temperature on the change of thiosulfinate content and the effects of n-hexane extraction and steam distillation on the change of sulfur compounds of garlic bulbs were investigated using N-ethylmaleimide color reaction, UV spectrophotometer and gas chromatograph. Thiosulfinate was detected in n-hexane extracts from garlic bulbs heated for 5 hours at 25℃ and 50℃ and for 30 minutes at 75℃ by the color reaction method. The UV spectrophotometer was more sensitive than the color reaction method to detect the thiosulfinate from even the extracts of samples heated for 1 hour at 75℃ and 15 minutes at l00℃.The quantity of diallyl disulfide which was formed from the decomposition of thiosulfinate increased to reach threefold values by 1 hour heating at 100℃ as compared with the samples heated for 15 minutes at 75℃, which well supported the above results. The steam distillation yielded extract of 0.12% which was mainly diallyl disulfide and the n-hexane extraction yielded extract of 0.10% at room temperature, however, the main compund was not diallyl disulfide but other unidentified compound.
