Preexisting lexicon for korean parsing has been built mainly based on syntactic information. However, Precise parsing of Korean sentence is difficult only with syntactic information, since korean is a partially free word-order which has frequent elimination of necessary constituents. Hence, including semantic information in the lexicon is essential in order to increase the quality of parsing. In this thesis, a prototype semantic lexicon for korean parsing is implemented. The components of the semantic lexicon are set of concepts, conceptual catalogues, conceptual relation, and a type hierarchy.

ABSTRACT - This study was performed to evaluate hepatoprotective effect of daewhang-whangryunhaedok-Tang(DWT) on liver injured rats induced by CCI_4 and the acute oral toxicity of it in mice. The activities of serum transaminase(ALT/AST), alkaline phosphatase(ALP) and lactic dehydrogenase(LDH), the levels of serum total cholesterol(TC) and triglyceride(TG), change of liver enlargement, and inhibitory activities of lipid perotidation, catalase and glutathione-S-transfrease(GST) in liver microsome were determined in hepatotoxic rats induced by CCI_4. DWT was significantly reduced the serum ALT, AST, ALP, LDH. TC and TG lecels. And, the increase of lipid peroxidation, decrease of catalase and GST activities in the liver microsome of CCI_4-intoxicated rat were significantly improved by the treatment of DWT. Male and female mice were administered maximum dosages of 5.000 mg/kg b.w. of DWT. After single oral administration of DWT to mice, we observed them daily for 2 weeks.DWT did not induce any toxic signs in the mortalitie, clinical signs, body weight changes, and gross necropsy finfings of mice. Based in these results. It is concluded that DWT may have the hepatoprotective effect on CCI_4 induced hepatotoxicity in rats. Also. DWT may have no side effect and its LD_50 value may be over 5.000mg/kg b.w. in mice.

Whangryunhaedok-Tang (WT) is formulated with Coptidis Rhizoma, Phellodendri Cortex, Scutellariae Radix and Gardeniae Fructus, and Daewhang-whangryunhaedok-Tang (DWT) is made by the combination of Rhei Rhizoma, a wellknown anticostipation drug in WT. Therefore, DWT has been evaluated for antihyperlipidemic effects on experimental hyperlipidemic rats and mice induced by corn oil and high cholesterol-diet. Oral administration of DWT significantly inhibited the increase of serum triglyceride and LDL-cholesterol levels, and the decrease of serum HDL-cholesterol levels in hyperlipidemic rats induced by corn oil. Also, oral administration of DWT significantly prevented the increase of serum total cholesterol, triglyceride and LDL-cholesterol, and liver total cholesterol and triglyceride in 1% cholesterol-diet fed mice. These results suggest that DWT is effective for the treatment of hyperlipidemia.

The purpose of this study is to present major performance of advanced facade systems including Double-skin facade, air flow window and air barrier system so that architects and engineers can use as a preliminary standard when adapting these systems to medium or large-sized office buildings. These systems are known as a well performing building element because of natural ventilation. energy savings and aesthetic appearance. But. the high construction cost and few application case in our country makes careful engineering more important. As a result, this study presents major performance matrix and characteristics of each system.

본 연구는 다슬기의 간 보호 효능을 확인하고자 하였다. 다슬기를 단백질 가수분해효소인 alcalase를 이용하여 가수 분해물을 얻은 후 실험을 수행하였다. HepG2 세포에 다슬기 가수분해물을 처리하였을 때 세포독성이 나타나지 않음을 확인하였다. 그리고 다슬기 가수분해물과 에탄올(1 M)을 가하여 24시간 후 세포생존율을 확인했을 때, 세포가 알코올 독성으로부터 보호되는 것을 확인할 수 있었다. 다음으로 다슬기 가수분해물의 간 손상 보호 효과를 Liber-DeCarli 알코올 액체 식이 급여와 동시에 경구 투여를 통한 알코올 단회 폭음(single binge)으로 알코올성 지방간과 염증을 유발시킨 마우스모델(NIAAA)을 사용하여 확인하고자 하였다. 이들 마우스 모델에서 알코올 식이 급여 후 초기에 체중이 감소하는 경향을 보이나 점차 비알코올 식이 급여군과 유사한 체중으로 회복하였다. 조직학적 관찰에서 알코올로 유도된 간 세포내 지방 축적과 지방성 염증이 에탄올과 함께 다슬기 가수분해물을 투여한 군에서 개선되는 것을 관찰 할 수 있었다. 또한, 알코올 투여에 의한 AST, ALT 및 ALP의 효소활성 증가가 다슬기 가수분해물 처리에 의해 억제되었으며, 만성 알코올 섭취에 의한 염증 매개 효소와 염증성 사인토카인의 발현 증가는 다슬기 가수분해물을 투여한 군에서 양성대조군에 비하여 유의하게 감소하였다. 이상의 연구결과를 종합해 보면 다슬기효소 가수분해물 소재는 알코올성 지방간의 예방 및 개선을 위한 기능성식품용 상업적 소재로서 높은 실용화 가능성을 시사한다. Alcoholic steatosis is a fundamental metabolic disorder and may precede the onset of more severe forms of alco-holic liver disease. In this study, we isolated enzymatichydrolysate from Semisulcospira libertine by alcalase hydrolysis and investigated the protective effect of Semisulcospira libertine hydrolysate on liver injury induced by alcohol in the mouse model of chronic and binge ethanol feeding (NIAAA). In an in vitro study, the hydrolysate protects HepG2 cells from ethanol toxicity. Liver damage was assessed by histopathological examination, as well as by quantitating activities of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). After the administration of S. libertina hydrolysate, fat accumulation and infiltration of inflammatory cells in liver tissues were significantly decreased in the NIAAA mouse model. The elevated levels of serum AST, ALT, and ALP activities, along with the lipid contents of a damaged liver, were recovered in experimental mice administrated with S. libertina hydrolysate, suggesting its role in blood enzyme activation and lipid content restoration within damaged liver tissues. Moreover, treatment with S. libertine hydrolysate reduced the expression rate of cyclooxygenase (COX-2), interleukin (IL)-1β, and IL-6, which accelerate inflammation and induces tissue damage. All data showed that S. libertine hydrolysate has a preventive role against alcohol-induced liver damages by improving the activities of blood enzymes and modulating the expression of inflammation factor, suggesting S. libertine hydrolysate could be a commercially potential material for the restoration of hepatotoxicity.
