  • 도시 지역의 영상에서는 가로수, 행인, 자동차 등 3차원 대상이 아닌 전경 물체가 빈번하게 나타남에 따라 건물 모델의 텍스처 생성에 어려움이 있다. 따라서 본 논문은 건물 영상에서 전경 물체에 의한 가림이 제거된 정명평행 텍스처를 생성하는 방법을 제안한다. 제안하는 방법은 사용자 조작을 이용하여 반자동으로 전경 물체에 의해 가려진 영역을 찾고, 이를 인페인팅 기법을 통해 채워넣음으로서 facade에 대한 텍스처를 생성한다.

  • Whole plants of Zostera asiatica were extracted twice with acetone/methylene chloride (A+M) and methanol (MeOH) in turn. The combined crude extracts were evaporated in vacuo and then the residue was partitioned between water and methylene chloride. The aqueous layer was fractionated into $H_2O$ and n-butanol and then the organic layer was also fractionated into 85% aq. MeOH and n-hexane, successively. The crude extracts and their solvent fractions were evaluated for their inhibitory effect on growth of human cancer cells AGS, HT-29, MCF-7, and HT-1080 cells by MTT reduction assay. Among samples tested, 85% aq. MeOH and n-hexane fractions showed strong cytotoxic effect against AGS, HT-29, and MCF-7 cells. On the other hand, for HT-1080 cell, 85% aq. MeOH fraction exhibited the strongest cytotoxic effect.

  • Crude extracts of Limonium tetragonum and their solvent-partitioned fractions were evaluated for their potential to scavenge authentic $ONOO^-$, and $ONOO^-$ derived from 3-morpholinosydnonimine (SIN-1). Four flavonol glycosides (1-4) were isolated by activity-guided separation. Their chemical structures were elucidated by extensive 2 D NMR experiments and by comparison with published spectral data. These compounds were also estimated for their peroxynitrite scavenging effects. The scavenging ratios of compounds 1-4 on authentic $ONOO^-$ were 56, 37, 56, and 54%, respectively, at a concentration of 1 ${\mu}M$. On the other hand, the inbihition ratios of compounds 1-4 against $ONOO^-$ generation from SIN-1 were 59, 39, 44, and 54% at the same concentration, respectively.

  • This report describes the remedial fields, symptoms, pathology, dosage, prescriptional constitution of 40 prescriptions related to the use of Magnoliae Cortex main blended prescriptions from Dongeuibogam. The following conclusions were reached through investigations on the prescriptions that use Magnoliae Cortex as a key component. Prescriptions that Magnoliae Cortex was taken as a monarch drug are utilized for 13 therapeutic purposes, for example, abdominal dropsy, abdominal lump. In particular, 27.5% of the prescriptions appear in the chapter of abdominal dropsy. Prescriptions that utilize Magnoliae Cortex as the main ingredient are used in the treatment of abdominal lump, abdominal dropsy. Magnoliae Cortex is used in pathogenic factors such as cold, congestion of Qi and used in pathology related to digestive system. The dosage of Magnoliae Cortex is 2pun(about 0.75g) to 3don(about 11.25 g), however 1don(about 3.75g) has been taken the most for clinical application. Pyeongwisan is the most useful base prescription which use the Magnoliae Cortex as the main component.

  • The aim of this investigation was to evaluate antioxidant activity of crude extracts from the halophyte Vitex rotundifolia, their solvent fractions, and isolated compounds (1-3). Antioxidant capacity was determined by measuring DPPH radical, and authentic $ONOO^-$ and $ONOO^-$ generated from 3- morpholinsydnonimine (SIN-1) in vitro as well as degree of occurrence of intracellular ROS, NO and GSH in mouse macrophage Raw 264.7 cells. From comparative analysis, MeOH extract, n-BuOH, and 85% aq. MeOH solvent fractions showed significant antioxidant effect in DPPH radical and $ONOO^-$ assay systems. Activity-guided purification of n-BuOH and 85% aq. MeOH fractions led to the isolation of flavonoids 1-3. Among them, compound 1 exhibited excellent antioxidant effect in all bioassay systems tested. On the other hand, compounds 2 and 3 revealed potent inhibitory effect against $ONOO^-$ generated from SIN-1, comparable with the positive control penicillamine.

  • The purpose of this study is to estimate the location and space configuration of Sauidang(四宜堂), which is a house in the late Joseon period. Sauidang was built by Hong Man-hoe(洪萬恢), the last son of Princess Jeongmyeong(貞明公主), was used as a house for Pungsan Hong clan(豊山 洪氏) for approximately 150 years, and is now defunct. However, the existence was estimated through Sauidang-ji("四宜堂志") compiled by Gwan-am Hong Gyeong-mo(冠巖 洪敬謨) in 1824. Based on the mention that "Sauidang was located in Hundo-bang(薰陶坊) of Ihyeon-dong(梨峴洞)" and the literature referring to "the site of Myeongryegung Palace(明禮宮)", this study estimated the location of Sauidang. Maps and photographic data in the modern age enabled us to examine the utilization cases of medium- and large-sized lots by examining the correlation with the current Embassy of the People's Republic of China in the Republic of Korea. In addition, it was possible to estimate the spatial configuration of Sauidang with a focus on words to clarify the detailed explanation of Sauidang mentioned in the literature and spatial relationship.

  • E coli strains isolated from pigs were investigated with respect to antimicrobial resistances and prevalence of R-plasmids. Also determined were properties of R-plasmids by plasmid conjugation, curing and southern hybridization using gene probes. All of 400 E coli strains were resistant to CL and SU, and 0.3% to 96.8% of the strains were resistant to most antimicrobials such as TC, PG, AM, SM, CP, GM, EM, NM, etc, while all strains were sensitive to AK. All strains were also multiply resistant to three to twelve antimicrobials. The resistances to PG, SM, TC, AM, CP, SU and ST were transferable and supposed to be mediated by R-plasmids which were opportunistic for transposition into chromosome. Plasmids bigger in size than chromosomal DNA were considered as R-plasmids and most plasmids in small size (<4Kb) proved as cryptic plasmids or nonconjugative R-plasmids. In a strain(No 99), AM resistant property was determined from both chromosomal DNA and R-plasmid DNA which is bigger in size than chromosome.

  • This study has attempted to examine the effect of Artemisia iwayomogi extract on antioxidant and liver function related enzymes in rats fed high fat diet along with B( )P administration. The activities of the serum glutamic oxaloacetic transaminase, glutamic pyruvate transaminase and alkaline phosphatase of the rats fed Artemisia iwayomogi ethanol extract were decreased compared to the control. Similarily, the activities of the enzymes were also decreased when the combination of B( )P and ethanol extracts were administered compared to the group adminstered only B( )P. On the other hand, high fat diet increased the above liver function related enzymes. The activities of antioxidant enzymes including GST, catalase and Cu,Zn SOD were significantly increased by feeding the extracts (p<0.01) in addition to the increase of tocopherol contents in the serum. These results suggest that Artemisia iwayomogi extracts can protect cell membranes from the damages by free radicals or hydroperoxides and further may lead to the protection from cancer risks.

  • 원기재문과 기준표본을 근거로 애기황새냉이(Cardamine manshurica (Kom.) Nakai)의 분류학적 실체와 형태적 특성을 재검토하였다. 그 결과, 애기황새냉이는 유럽에 분포하는 좀냉이(C. parviflora L.)와는 다른 분류군으로, 형태학적으로 황새냉이(C. flexuosa With)와 유사하나, 꽃과 열매의 크기가 작고 개화기가 빠른 특징에 의해 황새냉이를 비롯한 근연분류군과 종 수준에서 명확하게 구분되었으며, nrDNA를 이용한 ITS 구간을 이용한 분자생물학적 분석 결과에 의해서도 지지되었다. 따라서 본 분류군을 종으로 처리하는 것이 타당하다고 판단하였고, 학명은 C. manshurica (Kom.) Nakai를 정명으로 하였으며, 국명은 황새냉이보다 키가 작고 꽃이 소형인 특징에 기인하여 '애기황새냉이'를 채택하였다.

  • 한국산 대극속 3분류군에 대한 외부형태 형질과 학명을 재검토하였다. 줄기의 생장양상, 잎의 배열, 부속체의 유무, 자방 털의 유무, 종자의 형태 및 종부의 유무 등이 분류군들을 식별하는데 유용한 형질임이 확인되었다. 외부형태 형질, 기준표본 및 원기재문 등에 근거하여 낭독, 큰땅빈대 및 애기땅빈대의 정명은 E. fischeriana, E. hypericifolia 및 E. maculata로 밝혀졌으며, 정확한 종 동정을 위해 검색표를 제시하였다.
