In this paper, we propose a vision algorithm for the inspection of very small RF-chip inductor which is used in mobile-communication terminal. The proposed method divides coil part from the inductor body by local adaptive thresholding and integral projection method. After dividing work, the coil components are extracted by thinning and labelling techniques. The test items are the number of turns, the intervals in coil, and the measure of uniformity between the extracted lines. If the values of these are more than the specific value a tested product is decided bad one. In the simulation, the proposed method has a good performance.

In 30 rats divided into salt, ethanol and salt plus ethanol groups, the effect of ethanol on the course of hypertension induction with the salt ingestion was studied. The results obtained from the present study are as follows. 1) In salt group mean arterial blood pressure elevated to plateau (about 140 mmHg) in two weeks and the increased blood pressure was well maintained throughout entire experimental period. 2) By four weeks after ethanol ingestion, mean arterial blood pressure of ethanol group was slightly decreased followed thereafter by slow restoration to control value. And it was believed that decline of blood pressure observed in this case probably was not resulted from cardiac depression. 3) As mean arterial pressure in salt plus ethanol group remained rather low compared with that of salt group, it was suggested that ethanol may have a dose reduction effect in the course of hypertension induction by excessive salt ingestion. It was, however, not possible from the result of present study to decide that low blood Pressure in this group was resulted whether from enhanced sodium excretion activity of ethanol or from effect on blood pressure of ethanol itself.

Effects of water extracts of antler on blood sugar levels were studied in normal rats and KK-mice. a spontaneously diabetic strain of murine. Blood sugar levels were determined at 30, 60, and 120 minutes after intraperitoneal administration of 1 ml/kg or 2ml/kg AE into normal rats. A moderate but significant decrease in blood sugar level was noticed only in 30 minutes following 2 ml/kg AE administration. On the other hand no significant changes in blood sugar level was observed in KK-mice to which 1ml/kg/day AE had been given for 10 weeks. The results of present study strongly indicate that antler extract exerts no significant effect on blood sugar levels in experimental animals.

김기순,김준식,Kim, Kee-Soon,Kim, Joon-Seek 한국정보처리학회 2000 정보처리논문지 Vol.7 No.8

본 논문에서는 지도영상의 도로정보를 자동으로 추출할 수 있는 알고리즘을 제안한다. 제안된 알고리즘은 복잡한 지도영상에서 도로영상만을 추출한다. 추출된 영상은 세선화 방법에 의해 도로의 골격만으로 이루어진 영상으로 변환된다. 세선화된 영상은 여러 종류의 문제점을 포함한다. 이러한 문제점을 보정하기 위해 도로의 특성을 나타내는 Rutovitz 연결수에 의해 분류된 후 도로특성에 따라 개별적인 보정이 이루어진다. 여러 가지 지도영상에 대한 실험결과를 통해 제안한 방법의 유효성을 입증하였다. In this paper, we propose an algorithm which can automatically extract the road information in a map image. The proposed method extracts the road image in the complex map image. The extracted image is converted into the skeleton image by thining method. The converted image contains various problems. In order to correct these problems, after the road is classified by the number of Rutovitz-connectivity which represents the characteristic of road, those are respectively corrected according to the load characteristic. In the simulation, the proposed method has obtained good results for the various type of map images.

The effects of excess salt ingestion or/and a prolonged electrical stimulation of the hypothalamus on the arterial blood pressure were studied in cats. The average mean arterial pressure determined in 12 control animals were $112.2{\pm}2.6\;mmHg$. In 15 animals in which 2% NaCl solution (2g/Kg of body wegight/day) was given for 20 days, average mean arterial pressure elevated to $147.7{\pm}6.1\;mmHg$. It was also found in four of them that salt-induced high blood pressure started to decline when salt solution was replaced by tap water. On the other hand, No change in average mean arterial pressure was observed in 10 animals, whose hypothalamus had been electrically stimulated for 28 days. In 11 animals in which the hypothalamus was stimulated with simultaneous excess salt ingestion for 20 days, there was a marked elevation in average mean arterial pressure which, however, does not significantly differ from that observed in excess salt ingested group. From the results obtained from the present experiment, it is concluded that 1) the hypertension is induced by an excess salt ingestion in cats, 2) the mean arterial pressure of cats is not affected at least by an increment of sympathetic tone for 4 weeks resulting from the electrical stimulation of posterior area of the hypothalamus, 3) in sodium·induced high blood pressure cats, four weeks of increment in sympathetic tone by the hypothalamic stimulation does not further elevate mean arterial pressure.

The present study was undertaken to investigate effects of ethanol extracts of acorn (QAEE) on arterial blood Pressure and respiration, to find out the mechanism of depressor activity of QAEE,. add to determine lethal dosages of QAEE in rabbits and dogs. The results obtained were as follows: 1) After administration of 20 mg/Kg, 30 mg/kg, and 40 mg/kg of QAEE into rabbits the maximum depressor responses observed were respectively 16.3±1.4 mmHg, 28.7±2.0 mmHg and 45.6±3.1 mmHg, while mean depressor responses following administration of 40mg/kg, 60mg/kg and 80mg/kg of QAEE into dogs were 32.2±1.6 mmHg, 39.5±1.5 mmHg, and 47.0±1.6 mmHg respectively 2) Genenally depressor responses increased in proportion to dosage of QAEE administered whereas at same dosage of QAEE depressor responses were greater in rabbit than in dog. 3) It is suggested that depressor activity of QAEE resides mostly in its activity to activate vagus nerves and partly in Its activity to block beta-rceptors. 4) The lethal dosages of QAEE were 50 mg/kg to 60mg/kg for rabbi hue 90mg/kg to 100 mg/kg for dogs. 5) After QAEE administration respiratory rates were generally increased in the rabbit and the dog.

전기적 자극법은 심맥관계기능의 신경성조절을 이해하기위해 널리 이용되는 방법이며, 일반적으로 중추신경에는 고빈도, 말초신경에서는 저빈도 자극에 의해 최대반응이 유발된다고 알려지고 있으며, 이는 흥분파의 민도가 말초로 내려오며 감소되기 때물이라 해석되고 있다. 또한편 신경계의 어떤 단위위에서건 자극민도가 어느 한계를 넘으면 유발된 반응은 유지되지를 못하고 감쇠소실되는 것으로 이는 주로 시납스간 흥분파전달능 부전에 기인될 것이라고 믿어지고있다. 그러나 고위주추계와 말초를 연결하고 있는 척수에 있어서는 아직 최적전기적 자극조건도 분명히 알려져 있지 않을 뿐 아니라 이 부위에서도 고빈도자극시에 반응이 어느 정도 감쇠하는지에 대한 보고가 없기에 이를 추구코자 저자는 고양이의 상부경수를 면수와 연결부에서 완전 절단하기 전후 여러가지 자극조건으로 자극하여 몇 가지 결론을 얻었기에 보고하는 바이다. 1) 연수와 연결부에서 완전절단을 하기 전에는 경수(C₁ ~ C₂)의 백질, 회백질의 여러부위에서 심맥관반응이 유발되었으나 절단후에는 백질중의 만두부위(좌 2 ~ 3 mm, 배면으로 부터 0.3 ~ 1.0 mm및 2.5 ~ 3.5 mm)에만 반응이 유발되었으며, 이 두 부위는 심맥관계기능을 지배조절하는 원심성 섬유의 통로라고 사료되었다. 2) 최대반응은 자극조건(빈도 자극파지속시간 강도) 100/sec-1 mesc-3V 및 20/sec-3 msec-3V에서. 최장지속반응은 20/sec-3msec에서 유발되었으므로, 후자가 척수부에 있어 심맥관계반응을 유발키 위한 최적자극조건으로 생각된다. 3) 자극면도 20/sec 이하에서 반응유지가 잘된다는 결과는 생리적 조건하에서 척수를 통과하는 흥분파의 빈도가 20/sec를 넘지 않을 것이란 것을 시사한다. 4) 반응지속정도는 최초의 최대반응의 반으로 감쇠되기까지 소요되는시간 즉 50% 반응감쇠시간으로 표시하였으며, 척수에서는 대뇌피질 및 간뇌에서보다 심맥관계반응의 50%반응감쇠시간이 현저히 긴 것을 알 수 있었다.

구강 편평세포암종에서 Differential Polymerase Chain Reaction에 의한 Cyclin D1 유전자의 증폭에 대한 연구

김기순(Kee Soon Kim),김경욱(Kyung Wook Kim),이재훈(Jae Hoon Lee),김창진(Chang Jin Kim) 대한구강악안면외과학회 2000 대한구강악안면외과학회지 Vol.26 No.4

Neoplastic growth is characterized by alterations of oncogenes and antioncogenes. The interaction between activated oncogenes and functional deletion of antioncogene appears to be the driving force directing normal cells to uncontrolled growth resulting in tumor. In addition to those genes mentioned, other genes controlling the entry of cells into the cell cycle have recently been implicated in cancer development. The overexpression of the cyclin D1 gene, which has been mapped to 11q13, either by gene rearrangement or amplification has been noted in various malignant tumors. The product of the cyclin D1 gene forms a complex with cyclin-dependent protein kinases(CDK4) that governs a key transition in the cell cycle. The relationships between the overexpression of cyclin D1 assessed by immunihistochemistry and the amplification of the cyclin D1 gene by differential polymerase chain reaction(DPCR) using primers for dopamin D2 receptor gene in 13 cases of squamous cell carcinomas of the oral cavity have been studied. The semiquantitative assay of cyclin D1 amplification has been made by cyclin D1/dopamin D2 receptor(CD/DR) ratio. The results were as follows; 1. In the normal tissue and the tumor, the CD/DR ratios were 0.82 and 1.36 respectively. This implicates 1.65-fold amplification of cyclin D1 gene in tumor compared to that in normal tissue. 2. The tumor tissue which showed overexpression of cyclin D1 by immunohistochemistry revealed 2-fold amplification of cyclin D1 compared to the normal tissue. 3. The tumor tissue which showed mild expression of cyclin D1 by immunihistochemistry revealed 1.7-fold amplification of cyclin D compared to the normal tissue. 4. The cyclin D1 was overexpressed in the tumor tissue at the rate of 38%. Above results suggest that cyclin D1 has close correlation with the development of carcinoma in the oral cavity. But further studies were needed to elucidate the carcinogeneic mechanisms by comparative studies among cyclin D1, pRb and p53.
