법원도서관이 발간하는 판례공보를 기반으로 판결문 자동요약을 위한 학습 데이터들이 구축되고 있다. 그런데 판결문 요약에서는 뉴스 요약과는 달리 추출요약과 생성요약 방식이 함께 사용되는 특수성이 있고, 이러한 특수성 때문에 현재 판결문 요약 데이터셋이 요약 프로그램의 성능 향상을 이끌지 못하고 있다고 생각된다. 따라서 법률가들이 판결문을 요약하는 방식을 반영하여, 추출요약 방식으로 작성된 판결요지와 생성요약 방식으로 작성된 판결요지를 분리해서 요약 데이터셋을 만들 필요가 있다. 추출요약과 생성요약에 관한 데이터셋을 따로 구축하기 위해서는 판례공보의 판결요지를 추출요약과 생성요약으로 분류하는 작업이 필요한데, 감성 분석에 사용되는 알고리즘이 판결요지의 분류 작업에 응용될 수 있다는 것을 실험 결과로 알 수 있었다.

Garlic (Allium sativum) has been used as a source food as well as a traditional folk medicine ingredient since ancient times. Aged black garlic is a type of fermented garlic and is expected to have stronger anticancer and antioxidant activities than raw garlic. However, the mechanisms of their inhibitory effects on adipocyte differentiation and adipogenesis are poorly understood. In the present study, the effects and mechanisms of water extracts of raw garlic (WERG) and aged black garlic (WEABG) on adipocyte differentiation and adipogenesis in 3T3-L1 preadipocytes were investigated. Treatment with WEABG significantly suppressed terminal differentiation of 3T3-L1 preadipocytes in a dose-dependent manner as confirmed by a decrease in lipid droplet number and lipid content through Oil Red O staining, however WERG had no such effect. In addition, WEABG reduced accumulation of cellular triglyceride, which is associated with a significant inhibition of key pro-adipogenic transcription factors including peroxisome proliferator-activated receptor ${\gamma}$ (PPAR${\gamma}$), cytidine-cytidine-adenosine-adenosine-thymidine (CCAAT)/enhancer binding proteins ${\alpha}$ (C/EBP${\alpha}$) and C/EBP${\beta}$. Taken together, these results provide important new insight that aged black garlic might inhibit adipogenesis by suppressing the pro-adipogenic transcription factors in 3T3-L1 preadipocytes, and further studies will be needed to identify the active compounds that confer the anti-obesity activity of aged black garlic.

A lot of waterlogged shrouds and mummies have been found in tombs revered with lime of the Chosun Dynasty(1392-1910) of Korea. Shrouds were heavily polluted with greyish white material. Greyish white material, which adhered to shrouds excavated from tombs(16C and 17C), was submitted to FT-IR qualitative analysis and fatty acid analysis for cleaning. The results of the FT-IR qualitative analysis identified the main ingredient of the greyish white material as calcium salt of fatty acid, including a little of the fatty acids, lipids and proteins. Therefore the greyish white material fumed out adipocere which was formed from the degradation of the lipids in a dead body. From the fatty acid analysis, hydroxy fatty acids(10-Hydroxyhexadecanoic acid and 10-Hydroxyoctadecanoic acid), which were found in adipocere, were detected. The distribution of contents of fatty acids was also rimilar to that of adipocere which have a high proportion of palmitic acid of saturated fatty acid and a low proportion of oleic arid of unsaturated fatty acid. In view of the results of analyses, it was revealed that greyish white material adhered to shrouds was adipocere moved from a mummy.

Effect of polyphenolic compounds from green tea leaves and surfactant micelles on lipid oxidation in corn oil-in-water emulsion (O/W) wag determined. Concentrations of polyphenolic compound and surfactant in continuous phase of O/W were measured. Particle size of O/W with 17 mM Brij 700 and 5% corn oil increased with increasing concentration of polyphenolic compound (100-200 ppm). Concentration of surfactant in the continuous phase was lower than that of control. Lipid oxidation rates, as determined by the formation of lipid hydroperoxides and headspace hexanal, in O/W emulsions containing polyphenolic compounds decreased with increasing concentration of polyphenolic compounds (100-200 ppm). Inhibition of hydroperoxide and headspace hexanal produced via lipid oxidation by polyphenolic compounds in O/W was BHT>procyanidin B3-3-O-gallate>(+)-gallocatechin >(+)-catechin.

Reaction kinetics between 4,4'-dihexyl methane diisocyanate($H_{12}MDI$) and n-hexanol in toluene with dibutyltin dilaurate(DBTDL) as catalyst was studied by experimental measurements and mathematical modeling. Experiments were carried out at various temperatures, catalyst concentrations and [NCO]/[OH] ratios, and the reaction kinetics were described by two second-order reactions, the one between NCO and OH leading to urethane and the other between urethane and NCO leading to allophanate. The rate constants were estimated by the Runge-Kutta 4th-order method. Experiments and mathematical simulations showed a good agreement for various experimental conditions. The [allophanate]/[urethane] ratios at 90% conversion of initial NCO were estimated to be over 20% for most conditions employed in the present study, indicating that allophanate formation might significantly affect the properties of urethane polymers.

The alcohol fermentation was carried out to study the effect of aeration and unsaturated fatty acids added on the ethanol tolerance of Saccharomyces cerevisiae STV89 and Kluyveromyces fragilis CBS397. The cell growth rate and ethanol production rate was stimulated by aeration and the cell mass production and ethanol production were also substantially improved. With respect to strains, the maximum specific growth rate and overall ethanol productivity of K. fragilis under aerated condition were 6.4 fold and 4.4 fold higher than those of strictly anaerobic condition, although those of S. cerevisiae were increased 1.7 times and 2.3 times by aeration. The addition of ergosterol, linoleic acid and oleic acid also improved the cell growth and ethanol production of S. cerevisiae and K. fragilis. Thus it was found that oxygen and unsaturated fatty acids added played a decisive role on the increase of ethanol tolerance of yeast strains.

Radiolytic compounds of lipids, as hydrocarbons and 2-alkylcyclobutanones, were determined to detect the irradiated dried Mytilus coruscus. The detection methods were composed of fat extraction by Soxtec apparatus from dried Mytilus coruscus, isolation of hydrocarbons and 2-alkylcyclobutanones with a florisil column chromatography and identification of GC/MS. Concentrations of the radiation-induced hydrocarbons and 2-alkylcyclobutanones increased with the irradiation dose. The major hydrocarbons in irradiated Mytilus coruscus were pentadecane and 1-tetradecene originated from palmitic acid, and heptadecane and 1-hexadecene originated from stearic acid. 2-(5'- Tetradecenyl)cyclobutanone of 2-alkylcyclobutanones was high relatively. The radiation - induced hydrocarbons and 2-alkylcyclobutanones from dried Mytilus coruscus were detected at 0.5 kGy over and not detected at the non-irradiated.

Obesity is the leading metabolic disease in industrialized countries and is closely associated with coronary heart disease, hypertension, diabetes, and cancer. The objective of this study was to evaluate the anti-adipogenic effects of two roasted coffee beans, Vietnam robusta (VR) and Ethiopia Mocha Sidamo G2 (ES), as well as fermented coffee beans with Monascus ruber (MR) mycelium on differentiation of 3T3-L1 preadipocytes. Treatments with 1,000 ${\mu}g/mL$ of hot water extract from coffee beans significantly reduced intracellular lipid accumulation. In addition, VR more effectively inhibited transcription factors such as $PPAR{\gamma}$, $C/EBP{\alpha}$, FAS, and aP2 compared to ES. Further, ES fermented with MR showed more effective anti-adipogenic activity than non-fermented ES. These results suggest that VR and ES inhibit adipocyte differentiation which may contribute to their anti-adipogenic properties.

This study was performed to investigate the effect of chongkukjang intake on lipid metabolism and liver function in alcoholic fatty liver rats. Thirty-five 7-weeks old Spargue-Dawley male rats were used as experimental animals. After inducing alcoholic fatty liver, rats were divided into two groups and fed ethanol＋casein diet (ECD) or ethanol＋chongkukjang diet (EChD). At 10th, 20th and 30th days of the feeding experimental diet, rats were sacrificed to get blood and liver samples for analysis of blood lipids, lipid peroxides, antioxidative enzymes and biochemical indices of liver function. The mean food intake was not significantly different between ECD and EChD groups. Daily weight again of EChD group was significantly higher than that of ECD group at days 20 and 30. Serum total lipid, triglyceride and total cholesterol of ECD group were significantly higher than those of EChD group, while HDL-cholesterol was significantly higher in EChD group. Liver TBARS level of ECD group was significantly higher than that of EChD group. However, liver conjugated diene level was significantly higher in ECD group only at day 10. SOD, CAT and GPx activities of EChD group were significantly higher than those of ECD group at days 20 and 30. In the indices of liver function, GOT and GPT of ECD group were significantly higher than those of EChD group at day 10. LDH was significantly higher in ECD group. γ-GTP was significantly higher in ECD group only at day 20. Serum alcohol concentration of ECD group was significantly higher than that of EChD group at day 30. ADH and ALDH activities of EChD group were significantly higher than those of ECD group at day 30. Therefore, chongkukjang intake seems to give a beneficial effect on improving lipid metabolism and liver function by increasing HDL-cholesterol level, antioxidative enzyme activites, alcohol enzyme activities and decreasing serum lipids, liver TBARS and conjugated diene.

Common cruciferous vegetables, kohlabi (Brassica oleracea) and radish (Raphanus sativus), contain phytochemicals such as glucosinolates and carotenoids. Therefore, this study investigated the antioxidant and anti-adipogenic effects of kohlrabi sprout extract (KSE) and radish sprout extract (RSE). The total carotenoid and glucosinolate contents of KSE and RSE were $39.50{\pm}0.67$ and $76.73{\pm}2.75mg/g$, respectively. The total glucosinolate contents of KSE and RSE were $2.65{\pm}0.02$ and $8.13{\pm}0.54mg/g$, respectively. The in vitro-antioxidative activities of KSE and RSE were significantly increased in a dose-dependent manner. Furthermore, ${\beta}$-carotene and glucosinolate-enriched KSE and RSE significantly inhibited lipid accumulation and reactive oxygen species production during the adipogenesis of 3T3-L1 preadipocytes. These results suggest that glucosinolate-enriched KSE and RSE, especially RSE, can be used in the treatment of obesity and as a natural source of antioxidants.
