전영준,김진일 동의대학교 산업기술개발연구소 2005 産業技術硏究誌 Vol.19 No.-

This paper proposes a new system of mobile PDA monitoring for inspecting and managing the facilities of water, power and gas etc. The existing management system requires a hand-written report for the management of these facilities, however, it needs additional input time to update management databases. This system lowers efficiency and wastes human power. In this paper, we develop a new system of mobile handy terminals for citygas facilities and also provide inspection reports immediately and connect with the management database system using wireless equipment. Mobile communication is based on SSCE(SQL Server for windows CE) technology. This new system manages data in real time and reduces human power when applied to current working environments.

Conventional CT-guided needle localization has been reported many times, but a few reports of interventional procedures by using multidetector CT scan with CT-fluoroscopy have been described. We presented 36 cases of CT-fluoroscopy guided interventional procedures focusing on the puncture technique. Two cases of small pneumothorax and one case of pulmonary hemorrhage out of 2lcases after lung biopsy, were not needed any treatments We can easily and accurately access to the lesion by using CT-fluoroscopy and unique our marker system.

Serum lipid and lipoproetin levels were measured in order to compare with xanthoma and other dermatologic diseases. The measurement was done in 11 patients with xanthoma and 131 patients with other dermatologic diseases. The results are summarized as follows: 1. The levels of the serum lipid and lipoprotein of the patients with other dermatologic diseases were not different from that of the normal populations. 2. Eleven patients with xanthoma corresponded to Types IIb (5 cases), Ⅲ(4 cases) and Ⅳ (2 cases) of WHO classification. 3. The serum lipid and lipoprotein levels were higher significantly in the patients with xanthoma than in the patients with other dermatologic diseases.

The separation of rare earths minerals is verb difficult because of their similar chemical properties. The rare earth minerals are used as the mixed rare earth minerals or the misch metal without separation to each element. However, the high purity rare earths are recently produced commercially to each element so they there are used as the materials for high tech. Based on the characterization results for the raw minerals, we have developed a combined process containing gravity seperation, magnetic severation and flotation. The result obtained from this study is monazite concentration of TREO grade 69.11% and Recovery 56.02%.

In this paper, we designed supervised classification algorithms for effective classification of high resolution IKONOS satellite images. These include parallelepiped classifier, minimum distance classifier, maximum likelihood classifier and fuzzy classifier. The systems support various statistical data of training samples so that we can select the most effective training data. We used IKONOS satellite images for the input images and the characteristics of each of the classification methods were analyzed and compared. As a result, we verified that we can efficiently apply supervised image classification to high resolution satellite images.

연간 어획량으로 볼 때 오징어는 다른 어종 못지않게 중요한 종류이다. 오징어는 몸통뿐 아니라 내장과 간장 또한 이용가치가 매우 뛰어남에도 불구하고 그동안에는 사료용으로만 약간 사용되고 나머지는 대부분 폐기하였다. 본 연구에서는 이들 간장의 이용도를 넓힐수 있는 기초자료를 확보하고자 간장 중 일반성분과 지질 클래스의 변화를 월별로 조사하였다. 우선, 주문진항에서 4월에서 10월까지의 매월 한차례씩 살아있는 오징어를 구입하여 이들의 체중과 체장, 그리고 내장과 간장의 무게를 재고, 간장은 일반성분과 지질분석을 하였는데, 월별 체중 및 체장은 7월을 기점으로 여름철에 증가하며 체중도 같은 경향을 나타내었다. 그리고 간장의 무게도 체중의 증가와 비례하여 증가하였다. 비만도는 체장의 증가율에 비해 체중의 증가율이 높은 5월이 비만도가 가장 높았다. 같은 기간 중 일반성분의 변화를 보면, 수분은 대체로 감소하는 경향이고 단백질은 7월에서 9월 사이에 증가하는 경향을 보였다. 지질은 단백질과는 반대로 7월에서 9월 사이에 감소하는 경향을 보였으며, 회분은 매월 일정한 값을 나타내었다. 이러한 결과로 어체의 성장이 활발한 여름철에 단백질의 양이 증가하고 반면에 지질의 함량은 감소하는 것으로 나타났다. 한편, 지질 클래스에서 단순지질의 경우 NL은 봄철에서 가을로 가면서 점차 증가하는 경향을 보였고, 반면 S, PL은 감소하는 경향을 보였다. PL에서는 대부분 PC만이 검출되었으며, 계절적으로는 봄에서 가을로 갈수록 감소하는 경향을 보였다. Squid is one of the most popular species over the East coast of Korea and sold as raw or processed one at the market. However, the liver and intestine occupied more than 20% of whole body are discarded wastefully at present. At this point of view, we analyzed lipid classes and fatty acid composition of liver, and tried to develop the utilities on the useful components of liver and intestine of squid. Alive squids were collected at the port of Jumunjin, Kangwon-Do, Korea, from April to Oct., 1988, and measured the body length, body weight and liver weight. Chemical composition of liver was analyzed by general method. Moreover, lipid class of total lipid was analysed using Iatroscan. As a results of this study, body weight, body length and liver weight increased after July, and hepatosomatic index(HSI) increased after May. Moreover, condition factor was maintained at moderate level after May. Among chemical components, water content had negative correlation with lipid and concentrations of protein and ash were not changed remarkly. In analysis of lipid class, it was proved that neutral lipid(NL) fraction of total lipid(TL) contained triacylglyceride(TG), sterol ester(SE) and free fatty acid(FFA) while polar lipid (PL) fraction of TL contained phosphatidylcholine(PC) dominantly.

The blood supply and metabolism of malignant nodules are qualitatively and quantitatively different from those of most benign nodules. We evaluated the efficacy of dynamic CT for differentiation of benign malignant lesions. Thirty-six patients with malignant nodule(n=20), tuberculoma(n=7), and pneumonic consolidation(n=9) were evaluated by thin section dynamic CT. CT numbers of lesion and aorta were measured before enhancement, and 1 minute, and 3 minutes after enhancement. Malignant lesions(maximum, 31.1±10.7 HU) enhanced significantly more than tuberculoma(maximum, 13.5±12.9 HU), but mass/aorta ratios were not so significantly different between malignant lesions(maximum, 0.61±0.27), tuberculoma(maximum, 0.36±0.15), and pneumonic consolidation(maximum,0.49±0.14). Dynamic CT is very useful for differentiation of malignant lesions from tuberculoma.

우영대,--,--,--,--,-- 대한의생명과학회 2005 Biomedical Science Letters Vol.11 No.1

The etiologic agents of haemorragic fever with ranal syndrom (HFRS) in Korea are Hantaan and Seoul virus in the genus Hantavirus, family Bunyaviridae. In order to elucidate the role of maternal immunity to Hantavirus infection in rats, the protective effect of the maternal antibody were studies by using rats experimentally infected with Seoul virus strain HR80-39. Antibody titers of sera and viral antigen against Seoul virus were investigated by indirect immunofluorscence antibody technique (IFA). The dam sera had IFA antibody titers ranging from 1:128 to 1:1,024 after parturition. In fetuses, IFA antibody titers ranged from 1:16 to 1:64 just after birth, increased to peak titers ranged from 1:256 to 1:1,024 in the 2nd week after birth. Challenged newborn rats had IFA antibody titers ranging from 1:64 to 1:1,024 after inoculation. No viral antigen was detected in lungs or other organs of the newborn rats. The maternal antibody to Seoul virus was transferred prenatally through placenta and postnatally via colostrum from immune dams to their offspring. These results demonstrated that maternal antibody to Seoul virus was quite effective in protecting newborn rats against same virus infection.

Background and objectives : A disparity between clinical and urodynamic findings is commonly found and its application to the clinical management of neurogenic bladder is pratically as well embrassing as it reading. We investigated urodynamic study for the diagnosis and management of neurogenic bladder. Materials and methods : From July 1997 to June 2001, total of 83 patients of neurogenic bladder were evaluated by urodynamic study. Results : urodynamically, there were 20 cases(24%) showing detrusor hyperreflexia with detrusor external sphincter dyssynergia(DESD), 12 cases(15%) detrusor areflexia with low compliance. A disparity between the clinical and urodynamic assessment was noted in 26 cases(31%), clinically severe symptom with complication was particularily common in detrusor hyperreflexia with DESD, detrusor areflexia with low compliance and catheter indwelling patients. Conclusion : In neurogenic bladder, clinically symptom with complication was particularly common in detrusor hyperreflexia with DESD, detrusor areflexia with low compliance and catheter indwelling patients.
