著者들은 家兎와 人體로부터 採取한 血淸과 諸臟器組織을 使用하여 ALPI 電氣泳動像을 觀察하고 生化學的 定量法을 利用하여 ALP의 活性度를 測定試圖하였으며 臟器特異性 沮害因子에 對한 影響을 觀察하였다. 家兎 血淸 및 諸臟器組織 ALPI電氣泳動에서 血淸은 ±의 活性度를 가진 α2와 α2/β分劃을 나타내었으며 肝組纖은 血淸보다 빠른 移動度를 가진 ??의 α_1과 α_2分劃을 나타내었다. 그리고 肝, 骨, 腎 淋巴腺, 脾臟 및 腸組織에서는 顯著하게 높은 活性度를 나타내는 各各 서로 相異한 分劃을 볼 수 있었으며 人體諸 臟器와大體로 類似하였으나 家兎 血淸의 ALP는 사람에서 와는 다르게 肝組織의 分劃과 一致하지 않고 오히려 骨組織과 더 잘 一致되는 것 같았다. ALPI 活性度에 있어서 家兎의 諸臟器는 生化學的 定量法으로 腎 ALP의 活性度가 49.5B.L. units로 다른 臟器組織에 비하여 顯著하게 높았으며, 그 다음은 脾臟, 脊椎骨, 肝, 肺淋巴腺 및 脾 順으로 높은 活性度를 나타내었으며 人體에 있어서는 胎盤, 骨, 小賜, 脾臟, 肝 및 腎臟의 順으로 높았다. 臟器 特異性 沮害因子에 對한 影響에 있어서 胎盤分劃은 特有하게 耐熱性을 나타내었고 보다 urea低抗性이며 肝分劃은 neuraminidase에 對하여 移動度의 遲延을 招來하였다. The studies upon cellulose acetate microzone electrophoretic patterns, quantitative estimation and effects of organspecific inhibitor on ALP isoenzyme of rabbit and human sera and various organ tissues were performed. On electrophoretic pattern the tissue ALP from the liver bone kidney lymph node spleen and intestine showed the characteristic fraction of high activities. The electrophoretic mobility of rabbit serum ALP was not correspond to the liver ALP as observed in human serum and it appeared to be rather corresponded to the bone ALP, which seemed to be the origin of ALP in serum of rabbit. In the quantitative measurement of tissue ALP activity the kidney ALP showed the highest level and the activity of the skeletal muscle ALP was the lowest(1.5 B. L. units), while higher activities were observable in placenta, bone, intestine, spleen, liver and kidney in order. On the effect of organ specific physico chemical agents the placental ALPI was highly stable to the heat and relatively resistant to urea while other organ ALPI were on the contrary. The neuraminidase seemed to effect to the motility of liver fraction.

In the design of plate girder web panels, it is required to evaluate accurately the elastic buckling strength under pure shear. Whether or not the post-buckling strength is accounted for. Currently. Elastic shear buckling coefficients of web panels stiffened by transverse intermediate stiffeners are determined by assuming conservatively that web panels are simply supported at the juncture between the flange and the web. Although the notion of the real boundary condition at the juncture of the web and flanges to be somewhere between simple and fixed has been recognized from early days, the boundary condition has been conservatively assumed. Mainly due to lack of means to evaluate it in a rational manner. In this paper. A series of numerical analyses based on a three-dimensional finite element modeling is carried out to investigate the effects of the geometric parameters on the boundary conditions at the juncture between the flange and the web.

151종 생약제 추출물이 B형 간염 바이러스 표면 항원(HBsAg)과 항체(HBsAb)의 결합반응 그리고 HBV DNA polymerase 활성에 미치는 효과 : 한국산 각종 생약제를 이용한 B형 간염치료제의 개발

세계인구 43억명 중 B형 간염 바이러스 보균자는 2억 1천 5백만명이며 이중 78%인 1억 6천만명 이상이 아시아 대륙에 집중되어 있다. 한국도 B형 바이러스 간염의 침윤지대이다. 본 연구는 B형 바이러스 보균자 혹은 만성간염을 치료할 수 있는 생약제를 탐색할 목적의 일환으로 한국에서 시판하는 생약제 151종을 구입하여 증류수로 추출하고 여과한 후 냉동건조하여 HBs 항원에 대한 결합능, HBV DNA polymerase억제능, tumor necrosis factor(TNF) 유리에 미치는 영향, 그리고 galactosamine 유발 간염에 대한간장보호 작용을 조사하였다. 151종의 생약제중 0.16㎍/㎖ 농도에서 간염 vaccine 내에 함유된 HBs 항원과 결합하는 생약제는 지유, 가자, 복분자, 대황, 정향, 빈량, 산수유, 소목, 마황, 쇄양, 후박, 목과, 양강, 오약, 산사, 목단피 등 16종이었다. 이들 생약제중 대황(Rheum palmatum L. 大黃), 가자(Terminalia chebula R. 訶子), 지유(Sanguisorba officinalis L. 地楡), 복분자(Rubus coreanus M. 覆盆子)는 HBV DNA polymerase 활성도를 비교적 강하게 억제하였으며 빈량(Areca catechu L. 빈랑), 정향(Eugenia caryophyllata T. 丁香), 목과(Chaenomeles japonica L. 木瓜), 산수유(Cornus officinalis S. 山茱萸)는 약하게나마 HBV DNA polymerase 활성을 억제하였다. 또한 HBV DNA polymerase를 억제한 대황, 가자, 지유, 복분자, 빈량, 정향, 마황, 소목, 산수유를 대상으로 TNF 유리에 미치는 영향을 조사한 결과 소목을 제외한 8종의 생약제 모두가 대식세포를 자극하여 TNF를 유리시켰다. 그리고 장차 임상에 사용함을 전제로 HBV DNA polymerase를 억제한 대황, 가자, 지유, 복분자, 빈량, 정향, 마황, 소목, 산수유를 galactosamine 유발 간염(백서)에 투여하여 간기능 검사에 미치는 효과를 조사하였으나 간기능 검사상으로는 특별한 보호작용을 나타내지 못하였으며 생약제 단독 투여로서는 간기능에 대하여 나쁜 영향을 주지 않았다. Hepatitis B virus infection is major cause of acute and chrome hepatitis, cirrhosis of liver, and hepatocellular carcinoma. There are over 200 million carriers of hepatitis B virus in the world, nearly 80 % of whom live in the South East Asia, Korea is also highly endemic area of hepatitis B virus infection. This study was performed to evaluate the effect of extracts of traditional Korean herbal medicines on hepatitis B virus. 151 traditional herbs were extracted, filtered and lyophilized. Using 151 herbal extracts we tested binding capability to the HBs Ag, inhibition of HBV DNA polymerase, release of tumor necrosis factor (TNF), and protection against galactosamine induced liver damage. Among 151 herbs, 16 herbs (Sanguisorba officinalis L., Terminalia chebula R., rubus coreanus M., Rheum palmatum L., Eugenia caryophyllata T., Areca catechu L., Cornus officinalis S., Caesalpinia sappan L, Ephedra sinica S., Cynomorium songaricum R., Machilus thunbergii S., Chaenomeles japonica L., Alpinia officinarum H., Lindera strychnifolia V., Crataegus pinnatifida B., Paeonia suffruticasa A. ) had binding capability to HBs Ag which contained in the commercial hepatitis vaccine, at 16 ug/㎖ of concentratioa Among the above 16 herbs, Rheum palmatum L., Terminalia chebula R., Sanguisorba officinalis L., Rubus coreanus M. significantly inhibited the HBV DNA polymerase activity, and Areca catechu L., Eugenia caryophyllata T., Ephedra sinica S., Caesalpinia sappan L., Chaenomeles Japonica L., Cornus officinalis S. also inibited the HBV DNA polymerase activity but less effective. All of the herbs, except Caesalpinia sappan L., which inhibited the HBV DNA polymerase activity, actively stimulated the mononuclear cells to release tumor necrosis factor(TNF) in whole blood culture system. The herbs which inhibited the HBV DNA polymerase activity, did not show any protective effect in galactosamine-induced hepatitis in rats, but there was no direct toxic effect when herbs were administered alone.

金美京,嚴泰鵬 全北大學校 1994 論文集 Vol.38 No.-

The intracellular exoinulinase from Scytalidium acidophilum was purified to the specific activity of about 1,000 U/㎎ by ammonium sulfate precipitation, DEAE-Sepharose CL-6B, CM-Sephadex C-50, and HPLC gel filtration column. The maximum activity of the enzyme was observed between pH 3-3.5, which was the most acidic range among the optimum pHs of inulinases so far reported. Also, the enzyme could maintain 85% of its original activity after 6 h of incubation at 65℃, which had the industrial potential for inulin hydrolysis.

김태전,윤경하,최한영 서울보건대학 1998 서울보건대학 부설 한국보건과학연구소 논문집 Vol.5 No.1

Two Actinomycetes strains that it was excellent for degradablitiy of lignocellulose and lignin, and the highest for decolorization ratio of Remazol brilliant blue R(RBBR) dye, which was good relationship with degradabiliy of lignocellulose and lignin were identified finally with Streptomyces halstedii scabies SAl-36과 Streptomyces lavendulas SA2-14. Authors used these two strains to examine into the visiable spectrum and decolorization ratios of Azo dyes : amaranth, metanil yellow, orangeII. tropaeolin O, congo red, and Polymeric dye; poly R-478. The results to be examined were summarized as following. ① The visible spectrum of poly R-478, and amaranth, congo red. metanil yellow, orange II, tropaelin O were indicated that poly R-478 was 520/350nm. and amaranth. 522/324nm ; congo red. 490/434nm ; metanil yellow. 436/380nm ; orange II 484/310nm ; Tropaeolin O, 410/324 nm ② Each decolorization ratios of Azo dyes and Polymeric dye by Streptomyces halstedii scabies SA1-36 were showed that tropaeolin O was 79.3% ; poly R-478, 78.8% ; amaranth, 75.4%; orange II, 67.0% ; metanil yellow, 51.4% ; and congo red, 47.5%, so that the decolorization ratios of tropaelin O was the highest, and congo red, lowest. Consequently Streptomyces halstedii scabies SA1-36 was regarded as a good strain for the decolorization of tropaelin O into Azo dyes and poly R-478. ③ Each decolorization ratios of Azo dyes and Polymeric dye by Streptomyces lavendulas SA2-14 were showed that tropaeolin O was 81.4%; poly R-478, 80.0%; orangeII, 74.1%; congo red, 65.0%; metanil yellow, 57.7%, so that the decolorization ratios of tropaelin O was the highest. and secondly poly R-478. higher. and other dyes indicated the decolorization ratios of 57.7%-74.1%. Consequently Streptomyces halstedii scabies SA1-36 was regarded as a good strain than Streptomyces halstedii scabies SA1-36, and a good strain for the decolorization of tropaelin O into Azo dyes and poly R-478. ④ Each decolorization ratios of Azo dyes and Polymeric dye by Streptomyces badius ATCC 39117 (control group) were showed that tropaeolin O was 80.3% ; poly R-478, 79.0% ; amaranth, 70.7%; orange II, 66.4% ; congo red, 57.4% ; methenil yellow, 50.3%, so that the decolorization ratios by control group was the highest in tropaelin O, and secondly higher in poly R-478 as well as two experimental strains. ⑤ Two experimental strains were decolorized all of the examined dyes at the early days of culture, but control group, at the latter days of culture. In the above results, two experimental strains that were identified as Streptomyces halstedii scabies SAl-36과 Streptomyces lavendulas SA2-14 was regarded as a good strains for the decolorization of tropaelin O into Azo dyes and Poly R-478, and indicated 1-8% of high decolorization ratios than control group in all of Azo dyes and poly R-478, and among three strains Streptomyces lavendulas SA2-14 was thought as the best strain, when it were based on the days of culture, two experimental strains were decolorized all of the examined dyes at the early days of culture, but control group. at the latter days of culture. In the future, it will be necessary to invastigate what kind of dyes series with the object of more dyes which are decolorized more effectively by two experimental strains, also it will be more important subjects to examine into enzymes produced by Actinomycetes and establish exactly mechanism of decolorization by various produced enzymes.

인터넷 사용자의 급속한 증가와 전자 상거래의 발달로 신뢰성, 보안성, 확장성, 유연성 등의 기본적인 요구 사항 뿐 아니라 멀티미디어 응용 서비스에 대한 필요성이 제기되고 있다. 멀티미디어 컴퓨팅과 커뮤니케이션은 네트워크, 통신망, 오퍼레이팅 시스템에서 다양한 메커니즘을 필요로 한다. 대규모 분산 환경에서 QoS는 Video-on-Demand, News-On-Demand 등의 단일 매체에 대한 서비스와는 다르게 응용 매체에 대한 우선 순위 부여 및 상호 협력 구조적 서비스 및 MPEG 비디오 서비스와 같은 멀티미디어 응용 서비스에 대한 지원 능력을 요구하고 있다. 본 논문에서는 인터넷을 기반으로 대단위 분산 시스템 환경에서 QoS를 지원하기 위한 통합적 QoS 프레임워크로 E-QoS 모델을 설계하였으며, 향후 이를 바탕으로 한 세부 메커니즘의 설계 방향을 제시하였다. The huge Internet and electronic commerce shall be provided not only basic requirements of reliability, security extendibility, flexibility but also adaptive application service of multimedia data. There are required a lot of mechanism for network, operating system in multimedia computing and communication. In large distributed computing, QoS shall be provided a priority allocation service and an interactive infrastructure service as like not single media service of Video-on-Demand, and News-on-Demand but multimedia application service of MPEG video service. In this paper, supporting large distributed computing based on Internet, we propose a E-QoS Model as Integrated QoS Framework, and propose a direction of design for specific mechanism in the future works.

大學「캠퍼스」屋外空間의 利用行態 調査硏究 : 東國大學校 서울「캠퍼스」를 中心으로 A Special of Dongguk University Campus in Seoul

金炅濟,姜泰昊 동국대학교 1987 論文集 Vol.26 No.-

The outdoor space of university campus is different from the other buildings. It is the place where students stay long time and take various activities. Therefore, it has to be made objectively on an educational level, because its main users are students. However, it is our real state of things that we cannot prepare for outdoor space of university campus rationally and sufficiently. Because the preparation of its environment has been made extemporaneously and we have taken measures suited to the increase in quantity of university students. The objective of this study is to analyze the real state of using the outdoor space of university campus and to draw out problems, and then to take the 1st step for the establishment of landscape plan and design. The object place of this case study is the campus of Dongguk University in Seoul. The writers made the behavior map according to the observation of the actual place. And then they investigated using styles of students and analyzed students' way of thinking by posing some questions. As the result of this study, the object place of this case study has narrow outdoor space. And the degree of confusion at outdoor space is increasing, because various activities of students are done at a same time. Also, it is the real state of things that the outdoor resting place is insufficient quantatively and qualitively and shading trees are insufficient, too. Another important point to recognize is that the readjustment of pedestrian way and space is urgent, because the section between vechicle road and walk way is difficult. Therefore, at a more general level, these problems should be reflected in the establishment of the plan and design which will be in progress, so that the comfortable space of campus can be established.

김경태,김은이 건국대학교 산업기술연구원 2005 건국기술연구논문지 Vol.30 No.-

Line scratches are common degradations in old films. To support a demand of high quality of multimedia service, these scratches should be detected and restored. However, although many restoration algorithms have been researched, little have done in automatic scratch detection. This paper presents a texture-based object detection method for scratch detection. We use a multi-layer perceptron(MLP) to automatically make a texture classifier that discriminates between scratch regions and non-scratch ones in various environments. Multiresolution used to reduce influence of resolution. To assess the validity of the proposed method, it has been tested with all kinds of scratches, that is, principal/secondary scratches, alone/not-alone ones, and moving/static ones, and then experimental results shows that the proposed approach leads to not only robust but also efficient scratch detection
