박대훈,남중헌,배재학 울산대학교 1999 공학연구논문집 Vol.30 No.2

본 논문의 주제는 실질적인 원격 교육 시스템의 설계와 그 원형 구축에 관한 연구이다. 원격 교육 시스템에 관한 다양한 장점이 있지만 그것을 설계하고 구현하는 일선교사들에게는 전문성의 부족으로 어려운 실정이다. 본 논문에서는 Lotus Domino/Notes에서 제공하는 웹 페이지 설계 기능과 native 웹 개발 도구들을 비교하고, 그것이 일선교사들에게 원격 교육 시스템을 설계하고, 관리하는데 얼마나 용이한가를 연구하였다. This paper is concerned with the design and implementation of a practical distance learning system. Even though there are various advantages of distance learning systems, it is too difficult for the teachers to design and implement them. In this paper, the followings are studied: (1) comparing native web publishing tools with the web page design facilities which Lotus Domino/Notes provides, and (2) how much easier it will be with the facilities for teachers to design and manage a distance learning system.

Objective : The use of herbal therapy is becoming an increasingly attractive approach for the treatment of various inflammatory disorders. The Alpiniae officinari Rhizoma is popular in Aisa as a traditional herbal medicine. Alpiniae officinari Rhizoma is a species of the ginger family(Zingiberacease). Method : This study was performed to investigate the anti-inflammatory effect of Alpiniae officinari Rhizoma extract by the methods of "carrageenan induced paw edema" and "Lipopolysaccharide-induced inflammatory mediators in mouse macrophage RAW 264.7 cells". Result : We suggest that Alpiniae officinari Rhizoma extract decreased paw volume induced by plantar injection of carrageenan. Also Alpiniae officinari Rhizoma extract inhibited nitric oxide, prostaglandin E₂production and induced nitric oxide synthase, cyclooxygenase-2 protein expression in Mouse macrophage RAW 264.7 cells stimulated with lipopolysaccharide. Conclusion : This study shows that Alpiniae officinari Rhizoma extract seems to have anti-inflammatory effect by inhibition of nitric oxide, prostaglandin E_(2) production and nitric oxide synthase, cyclooxygenase-2 protein expression.

The study examines the medical potential of an ultrasonic C-scanning technique and for diagnosis of the fatigue induced micro-fractures of the bone. In general, it is not easy to detect the micro­fracture by a simple radiological technique. In the study, the micro­fractures were made on the tibia taken from pigs using a three point bending. Comparison was made between the ultrasonic C-scan images (25 MHz) and X-ray images of the bones with the micro-fractures, It was found that the micro-fractures invisible on the X-ray images were observed on the ultrasonic images. It is proposed further in-vitro and in-vivo studies making the ultrasonic C-scan technique clinically useful for the diagnosis of the fatigued induced micro-fractures of the bone which are not possible to detect by the conventional radiological method.

ELISA에 의한 뇌척수액내 Fibronectin의 측정과 임상적 의의

김숙희,박충서,이병헌,조준승 慶北大學校 醫科大學 1990 慶北醫大誌 Vol.31 No.3

신경계 질환의 진단은 임상 소견과 뇌척수액 검사소견 등을 기초로 하고 있다. 그러나 이들 소견이 각 질환간의 감별에 분명한 도움을 주고 있지는 못하고 있다. 이에 본 연구에서는 뇌척수액 fibronectin을 측정하여 여러 신경계 질환과의 관련을 조사하고 나아가 이들 질환의 감별에 도움을 얻고자 하였다. Fibronectin은 뇌척수액내 미량으로 존재하므로 이의 측정을 위하여 먼저 측정능이 좋은 ELISA를 개발하였다. 그 결과 농도가 10 ng/ml에서부터 100 ng/ml의 범위내에서 뇌척수액 fibronectin 농도를 측정할 수 있었다. 결핵성 뇌막염 9례, 바이러스성 뇌막염 5례, 세균성 뇌막염 2례를 포함한 기타 신경계 질환 8례 및 정상대조군 18례 등 총 40례를 대상으로 뇌척수액내 fibronectin농도를 조사한 결과, 결핵성 뇌막염군은 4.21±2.32 ㎍/㎖, 바이러스성 뇌막염군은 0.9±0.79 ㎍/㎖, 기타 질환군은 2.05±2.48 ㎍/㎖, 그리고 정상대조군은 1.35±0.84 ㎍/㎖의 평균값을 보여 결핵성 뇌막염군이 기타 질환군을 제외한 타 질환군들에 비해 통계적으로 유의하게 높은 값을 보였다(p<0.01). 결핵성 뇌막염의 경우 1례를 제외하고는 모두 2.9 ㎍/㎖ 이상이었고, 3례(38%)에서는 4.6 ㎍/㎖ 이상이었던 반면, 바이러스성 혹은 무균성 뇌막염에서는 1례에서만 2.2 ㎍/㎖이고 나머지는 모두 1 ㎍/㎖ 이하로 나타났다. 이상의 결과로 보아 뇌척수액내 fibronectin농도의 측정은 결핵성 뇌막염과 바이러스성 뇌막염의 감별진단에 유용하리라 생각된다. The diagnosis of neurologic diseases is based on the clinical symptoms and cerebrospinal fluid findings. These findings, however, are often ambiguous. This study aims to evaluate the diagnostic value of cerebrospinal concentration of fibronectin. Fibronectin level in cerebrospinal fuid was measured by ELISA which could detect fibronectin in the range from 10 ng/ml to 100 ng/ml. Nine cases of tuberculous menigitis, 5 cases of viral meningitis, 8 cases of miscellaneous neurologic conditions and 18 cases of normal controls were studied. The mean value of fibronectin level in cerebrospinal fluid in tuberculous meningitis was 4.21±2.32 ㎍/㎖, in viral meningitis 0.9±0.79 ㎍/㎖, in miscellaneous neurologic conditions 2.05±2.48 ㎍/㎖ and in controls 1.35±0.84 ㎍/㎖. The fibronectin level in tuberculous meningitis was significantly higher than in other groups except the miscellaneous neurologic conditon(p<0.01). Cerebrospinal fluid fibronectin level appeared to be useful to differentiate tuberculous meningitis fro viral meningitis. Those levels were higher than 2.9 ㎍/㎖ in all except one case and higher than 4.6 ㎍/㎖ in 38% of tuberculous meningitis cases, but, 2.2 ㎍/㎖ in only one case of viral meningitis and lower than 1.0 ㎍/㎖ in all except one case of viral meningitis. It is suggested that measurement of fibronectin level in cerebrospinal fluid is a useful test for diagnosis of tuberculous meningitis, especially for differential diagnosis between tuberculous and viral meningitis.

The matrix of ductile cast iron are welded by pre-heating it at 300℃ in the room temperature. Through the mechanical, non-desbructive testing and analysis of the composition. the possibility if arc welding of ductile cast iron are studied as follows; 1. L electrode is the best among them in weldability, impact value and machinability. The next is LB electrode followed by S electrode. C electrode is last. However, the tensile strength showed in the following order: LB, S, L, C. 2. LB, S, L, C, all are available for the welding of cast iron. 3. The above experiment showed that L and LB are good in general. In addition LB is low in price, we therefore prospect that it will be widely used as the electrode for cast iron.

Colchicine is an alkaloid that has been used for treating acute gouty arthritis, psoriasis, scleroderma and Behcet's syndrome. Colchicine decreased liver fibrosis in rats with carbon tetrachloride induced cirrhosis and in patients with many liver diseases. Therapeutic oral doses of colchicine may cause nausea, vomiting, abdominal pain and diarrhea. The adverse effect of colchicine associated with the dose is bone marrow suppression, and especially neutopenia. Neutropenia has often been reported in patients have taken an overdose of colchicine. We describe a 64-year-old female liver cirrhosis patient with neutropenia that was induced by a therapeutic dose of colchicine.

Park, Tae-Joon,Hwang, Joo-Yeon,Go, Min Jin,Lee, Hye-Ja,Jang, Han Byul,Choi, Youngshim,Kang, Jae Heon,Park, Kyung Hee,Choi, Min-Gyu,Song, Jihyun,Kim, Bong-Jo,Lee, Jong-Young Korea Genome Organization 2013 Genomics & informatics Vol.11 No.3

Liver enzyme elevations, as an indicator of liver function, are widely associated with metabolic diseases. Genome-wide population-based association studies have identified a genetic susceptibility to liver enzyme elevations and their related traits; however, the genetic architecture in childhood remains largely unknown. We performed a genome-wide association study to identify new genetic loci for liver enzyme levels in a Korean childhood cohort (n = 484). We observed three novel loci (rs4949718, rs80311637, and rs596406) that were multiply associated with elevated levels of alanine transaminase and aspartate transaminase. Although there are some limitations, including genetic power, additional replication and functional characterization will support the clarity on the genetic contribution that the ST6GALNAC3, ADAMTS9, and CELF2 genes have in childhood liver function.

Park, Jung-Joon,Park, Heungsun,Kim, Yong-Heon,Kijong Cho Korean Society of Applied Entomology 2000 Journal of Asia-Pacific Entomology Vol.3 No.2

A sequential sampling procedure for classifying the ratio of prey/predators developed by Nyrop (1988) was examined to implement for a biological control in the greenhouse roses. The procedure was combined with a sequential density classification procedure for use in monitoring a phytophagous mite, Tetranychus urticae Koch, and a phytoseiid predator, Phytoseiuluss persimilis Athias-Henriot. This procedure was required four Parameters: Means and variances for f urticae and P persimilis, correlation coefficient between densities of prey and predates and critical ratio of prey and predator. The parameter values used in this study were 0.725 for the correlation coefficient and 10 for the critical ratio. The variances for each species were estimated using a Taylor\`s power law model. The procedure is proven to be successfully applicable to T urticae and f persimilis system in greenhouse roses at two action threshold levels of f and 10 f urticae per three-leaflet leave. The limitations and implementation of this procedure is also discussed.
