저위교합이란 능동적 맹출기 동안이나 이후 해당치아의 교합면 방향으로의 성장이 멈추어 다른 치아들보다 하방에 존재하는 것을 말한다 저위교합치의 결과로 침하치의 만기잔존, 부정교합, 증가된 치아우식 감수성과 치주질환의 가능성, 계승치의 이동 등이 나타날 수 있다. 따라서 조기진단 및 적절한 처치가 필요하다. 저위교합치의 치료는 저위교합 정도나 후속 영구치의 발육정도에 따라 보존에서 발치까지 다양하다. 영구 계승치가 없거나 부분적인 침하치가 치주적으로 건전한 경우, 공간문제를 발생하지 않는 경우 보존적인 접근이 추천되기도 한다. 그러나 계승치가 존재하고 맹출이 지연되는 경우, 국소적인 염증반응과 관련되는 경우 교정적인 치료가 필요한 경우에는 발거가 필요할 수도 있다. 특히 저위교합된 유구치의 상방으로 인접치가 경사되어 악궁장경에 문제를 초래할 위험이 있는 경우 외과적인 발치가 필요할 수도 있으며 경사가 심한 경우 발치를 위한 외과적 접근이 힘들 수 있다. 심하게 경사된 인접치로 인하여 저위교합치의 외과적 발거가 힘들 환아에서 가철성 교정장치를 이용하여 공간확보를 진행 하였으며 보다 용이하게 치아를 발거할 수 있었다. Infraclusion may be defined as teeth that stop their relative occlusal movement in the dental arches during or after the period of active eruption and then remain under the occlusal plane. Delayed exfoliation, malocclusion, increased susceptibility to dental caries and periodontal disease of both the neighboring teeth and retained molar, and dislocation of' the successor are the consequencces of infraclusion of primary molars. Therefore, early diagnosis and appropriate treatments are necessary. The therapeutic approach of' the infracluded teeth varied from preservation to extraction. The teeth with simple infraclusion without any signs of interference with occlusal and jaw development may be examined periodically with fellow-up check and radiographically. However, if the infracluded tooth interferes with normal eruption of successor or shows any sign of delayed resorption, or the tipping of adjacent teeth or supraeruption of op-posing teeth is expected, the teeth inflicted should be extracted and appropriate measures should be provided in order to maintain the normal development of occlusion and dentition. The adjacent teeth which have been collapsed over a infracluded deciduous teeth can disturb the arch length perimeter. In such cases, surgical approach might be necessary, although it would be difficult when teeth are severly leaned. However, an easier surgical access have been obtained by space regaining procedures, in young patients whose arch length has been shortened due to the infracluded teeth.

This study was devised to observe some effects of dietary condition on metabolic change in rats. The experimental young rats were fed on the diet deprived of one among protein, lipid and carbohydrate, that is, protein free diet, lipid free diet or carbohydrate free diet for 3, 7 or 15 days; and total nitrogen, pyruvic acid, cholesterol, acetylcholine contents and cholinesterase activities in the liver and serum were observed. The results obtained are summarized as follows: 1. The protein metabolism in the body, in the condition of sufficient calory, is normally progressed to some degree with the protein free diet, and is apt to operate more effectively with the lipid free diet than with the carbohydrate free diet. 2. The pyruvic acid contents in the liver is highest in the protein free diet groups and even the carbohydrate free diet and lipid free diet groups show a tendency to leading to the normal calory metabolism. 3. The total cholesterol contents in the liver is higher in the protein free diet group than either of the other free diet groups, and the ester form cholesterol is decreased in the lipid fee diet group. 4. With cholinesterase activity increased, the acetylcholine contents is increased, fed with the protein free in diet in early stage, but it is decrease, fed for 15 days. It is concluded from the above results that the metabolic change in the body, even in the condition of unbalanced diet, operates normally for a short period, which may be due to the homeostasis mechanism.

본 연구에서는 실제 상용하고 있는 각 차음료가 온도, 시간 및 추출 횟수에 따른 성분의 함량의 차이를 관찰코져 시판되고 있는 한국산 녹차, 우롱차 및 홍차를 대상으로 추출방법을 달리한 후 茶浸出液중의 주요성분인 catechin, vitamin C 및 여러가지 무기질의 함량을 측정하여 다음과 같은 결과를 얻었다. 1. 차침출온도에 따른 침출액중의 catechin과 vitamin C 함량의 차이를 볼 때 온도가 높을수록 많이 추출되었다. 2. 같은 온도라는 침출시간에 따른 차이를 관찰한 결과 시간이 길수록 침출액중의 catechin과 vitamin C의 함량이 증가되었다. 3. 녹차는 우려낸 횟수에 따른 catechin의 함량 차이는 처음에 비하여 2회 추출시약 51%, 3회추출시는 71% 감소하였다. 4. 차의 각 무기원소에 따른 함량을 비교시 Mg은 우롱차가 가장 높고 K, Mn은 녹차가, Zn, Cu 그리고 Fe는 홍차가 가장 높게 나타났다. 5. 녹차, 우롱차의 경우 대체로 무기질의 침출정도가 온도가 높을수록 오히려 감소하는 경향을 나타내었고 홍차는 Mg, K을 제외하고 모두 증가하였다. 6. 각 침출액중의 대부분의 무기질 함량은 추출횟수가 증가할수록 감소하였다. 7. 시료로 사용한 녹차, 우롱차, 홍차의 vitamin C 함량은 녹차, 우롱차, 홍차의 순으로 높게 나타났다. 8. 녹차를 추출한 횟수에 따른 vitamin C 함량은 1회에 비해 2회 추출시 약 36%, 3회 추출시 약 62% 감소되었다. 9. 5g의 녹차를 80℃에서 2분간 침출한 액중에서는 catechin은 100ml당 0.34g, Mg은 2.229mg, Ca은 0.365mg, K은 39.77mg, Zn은 0.037mg, Cu은 0.010mg, Fe는 0.001mg, Mn은 0.581mg이며, vitamin C는 9.65mg이 함유되어 있었다. This study was to compare the ingredients which are contained in usual Korean teas in-depednence on leaching temperature, time and number. The main contents i.e. catechin, vi-tamin C and other minerals extracted from Korean commercial green tea, oolong tea and black tea were measured. The resluts are as follows; According to extracting temperature, the higher temperature made catechin and vitamin C extracted more. For the same leaching temperature, the longer time the more catechin and vitamin C. In case of extracting number, the contents of catechin was decreased a-bout 50% and 70% at second time and third, respectively in comparasion to the first time. For minerals from teas, management(Mg) was most in oolong tea, potassium(K)and manganease(Mn) and in green tea and iron(FEe) was in black tea respectively. Most min-erals from greentea and oolong tea were extracted less as leaching temperature was in-creased. But in black tea minerals other than Mg and K were more at increased tempera-ture. Most minerals in extractions were decreased as leaching number was increased. The content of vitamin C in the experimental samples(tea) was most in green tea, next in oo-long tea and third in black tea. In comparasion with the first extraction vitamin C was de-creased about 35% and 60% at 2nd and 3rd leach, respectively.

권순경,이은방,김미경,박영남 德成女子大學校 藥學硏究所 1998 藥學論文誌 Vol.9 No.1

Allylthio group of the sulfur compounds of garlic oil plays an important role for prevention and treatment of hepatic diseases to be introduced by toxic substances or carbon tetrachloride. Thus allylthio group as a pharmacologically active group was introduced into pyridazine nucleus and a substituent such as halogen or alkoxy was also introduced into the para-posi-tion of allylthio group. Three allylthiopyridazine derivatives were synthesized and their hepatoprotective activities were screened in rat. Under the three compounds (6, 7, 8), 7 and 8 (methoxy-, ethoxy-substituent) are hepatoprotective, but 6 (chloro-substitu-ent) is negative.

Wu Jian-ren, a typical writer in late Qing Dynasty, created 《The New Story of the Stone( 新石頭記: Xin Shi Tou Ji)》in 1905, using the same characters and plotline in 《The Story of the Stone (紅樓夢: Hong Low Mong》. In the first part of this book, Jia Bao-yu(賈寶玉), who disappeared in the last chapter of 《The Storyof the Stone》, showed up again and divulged old habits of Qing Dynasty which had been habitually practised by corrupted bureaucratism. In the last part, the author vividly described the advanced, utopian society based on independently developed science and technology by the viewpoint of Jia. Consequently, he put an emphasis on the social reform of old society. Furthermore, he made concrete suggestions in order to build a new society. This book employed strong satire to criticize Qing Dynasty using mythology of "Bu tian(補天)". The writer also continued to emphasize the virtue of self-reliance, independent economy in order to defend fragile, corrupted Qing Dynasty threatened incessantly by Western imperialists. In addition to the importance of science and technology developed by independent national wealth, he also believed that the utopian society should be ruled by building valuable virtues and culture. Although this book is a typical satire novel based on Mei Ci Satire theory, it presents its unique pattern with unconventionally organized descriptions on the utopian society by providing complete political, social, economic alternatives to his current society, instead of harsh criticism. It cannot be denied that the worth of book in the traditional Chinese satire novel owns to his unique imagination honed by Chinese classics.

In this paper, an effective algorithm which can detect moving objects from the image sequences and classify an intruder from other moving objects is presented for an implementation of unmanned surveillance system. The proposed algorithm uses a stick figure model for features of the moving object since the stick figure model can be represent the characteristics of the moving objects. The stick figure model is extracted by applying the thining algorithm to the binary difference image between the reference and the image of a moving object. The computer simulation is carried out to analyze the performance of the proposed algorithm. The results show that the algorithm can discriminate a moving person and a moving animal with high degree of reliability.

In this paper, we propose an efficient content-based image retrieval method using the color and wavelet based pattern features. The pattern features are extracted from the invariant moments of the high-pass band image through spatial-frequency analysis of wavelet transform and color features are extracted from color histograms of the global image. The proposed image retrieval method is called a pattern and color feature based query(PCBQ). Forward PCBQ and backward PCBQ perform similarity matching of cascade form using the pattern and color features. The first step matching is carried out to find the candidate images which are most similar to the query image using the pattern or color features. The second step matching is executed using the feature vectors for the accurate retrieval from the candidate images of the first step. Weighted PCBQ performs weighted similarity matching of parallel form using the pattern and color features. The experimental results show that the proposed retrieval systems yield more improved retrieval accuracy than the previous methods.
