개솔새(Cymbopogen tortilis) 精油가 胃液分泌 및 胃運動에 미치는 影響
朴駿瀅,鄭基坤 慶北大學校 1984 論文集 Vol.38 No.-
Cymbopogen tortilis is native weeds which is widely distributed in Korean fields and mountains and its flower contains a strong aromatic essential oil. It is known that the essential oil of Cymbopogen tortilis contains borneol, cadinene, camphene, and elemicin etc. But, there is no report about the effect of essential oil of Cymbopogen tortilis or its constituents on the gastric secretion and the gastric motility. To examine the effect of essential oil of Cymbopogen tortilis on the gastric secretion in rats and the gastric motility in pigeons, this paper was investigated. The results were as follows. The intraperitoneal administration of 1% essential oil solution of Cymbopogen tortilis at the ratio of 1.0ml, 0.5m1, 0.25ml/l00g B.W. to rat reduced their average gastric secretion volume to 2.1±0.29m1, 4.4±1.02m1, and 4.7±1.04ml respectively. In contrast to 9.5±1.3m1 of control rat's secretion. these numbers show 77.89%, 53.68% and 50.53% of gastric secretion inhibition rate. In pigeons, transient gastric inhibition which can be divided into 2 types was observed by the intraperitoneal injection of the drug at the same ratio to that of rats. In one type, gastric motility was inhibited in the state of transient gastric relaxation after drug administration, it recovered to normal with time. In the other type, gastric motility was inhibited transient gastric relaxation, soon its tone moved into contraction state, maintained this condition for some time, and this condition gradually recovered to normal. In conclusion, the essential oil of Cymbopogen tortilis inhibits strongly gastric secretion in rats and transiently gastric motility in pigeons.

In this study, the relationship between substance use and high-novelty seeking was tested using Cloninger et al's 240-items Temperament and Character Inventory(TCI) in 34 substance users(32 methamphetamine and 2 cocaine dependence disorders), 80 normal controls and 48 schizophrenics Demographic characteristics and substance use-related past history were taken by semi-structured interview. Subjects were aged 18-45 and general psychopathology was screened by Symptom Checklist 90 revised. The results were as follows. 1) Among temperament subdivisions in the TCI, novelty seeking(NS) was significantly higher in the substance users(22.1±4.9) than the normal controls(18.0±5.0) and the schizophrenics(15.6±3.3). There were no significant differences in other temperament subdivisions such as harm avoidance, reward dependence and persistence, neither character subdivisions such as self-directiveness, cooperativeness and self- transcendence. 2) A significant inverse correlation was found between NS and age both in the substance users(r=0.274) and the normal controls(r=0.468). This study suggested that the biogenetic temperament characteristics in substance use disorder were related with their high novelty seeking, not low harm avoidance.

본 논문에서는 각 광원의 위치에 대해 미리 구한 라디안스 맵에 시간-색 공간에서의 반사요소 분리방법을 적용하여 난반사 라디안스 맵과 거울반사 라디안스 맵을 구한다. 픽셀 BRDF를 얻기 위한 입력으로 반사요소가 분리된 라디안스 맵을 사용하였다. 따라서, 광원의 조작에 대해 난반사와 거울반사 이미지를 각각 제어할 수 있다. 시간-색 공간에서의 반사요소 분리방법을 사용함으로써, 이미지의 전역 정보가 아니라 지역 정보만을 이용한 반사요소 분리가 가능하다.

These experiments were conducted to get high production and quality of whole crop winter cereals, Oat, Wheat and Triticale, in the paddy field. These three whole crop winter cereals are got later harvest than whole crop barley, so there are more production of forage. Its harvest time was the end of May or the early of June in the south area of Korea. Mixed cultivations of Oat and Wheat (MCOW) was got more production over 15 percents in the dry wight, and then contents of crude protein (CP) in MCOW were higher than single cultivation of Oat. And Relative feed values (RFV) of MCOW were higher than single cultivation of Oat. Mixed cultivations of Oat and Triticale (MCOT) were got more production over 7 percents in the dry wight than single cultivations of Oat, but contents of CP in MCOT were not changed in all plots. And RFVs of MCOT were higher than single cultivations of Oat.

These experiments was carried out to get high quality of forage to cultivate mixed barley and winter pea with different seeding rates, 200 and 140 kg/ha in barley, and seeding rates in winter pea were 0, 50 and 100 kg/ha. And these were tested in Iksan from 2006 to 2007 for two years. The results were followed. Dry weight in only barley seeding of 200 kg/ha was 0.9 ton/ha higher than only barley seeding of 140 kg/ha. Fresh and dry weight in barley seeding of 200 kg/ha and mixed winter pea were each 1.4, 0.7 ton/ha higher than barley seeding of 140 kg/ha and mixed winter pea. And crude protein in barley seeding of 200 kg/ha and mixed winter pea was from 0.3 to 0.8 %, and 140 kg/ha and mixed winter pea was from 1 to 1.6 %. The rates of fresh and dry weight to all yield in winter pea were each from 8 to 15, from 4 to 21 % in barley seeding of 200 kg/ha and mixed winter pea, and were from 9 to 20, from 5 to 26 % in barley seeding of 140 kg/ha and mixed winter pea.

흉부 X-ray 영상은 폐 질환을 진단하는 기본적인 도구로써 널리 사용되고 있다. 정확한 진단을 위해 흉부 X-ray 영상의 품질을 평가하는 과정을 거쳐야 하는데, 이 과정은 주관적인 기준에 따라 수작업으로 이루어지기 때문에 많은 시간과 비용이 소요된다. 따라서 본 논문에서는 임상 현장에서 사용되는 흉부 X-ray 영상 화질 평가 가이드라인을 기반으로 인공음영, 포함범위, 환자자세, 흡기정도, 그리고 투과 상태의 5가지 품질 평가를 자동화하는 도구를 제안한다. 제안하는 도구는 품질 판단에 소요되는 시간과 비용을 줄여주고, 더 나아가 흉부 병변 진단을 위한 학습 모델 개발의 양질의 학습 데이터를 선별하는 전처리 과정에 활용될 수 있다.
