Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

尹草窓의 生涯와 草窓訣에 關한 硏究

金準泰,尹暢烈 대한한의학원전학회 1992 대한한의학원전학회지 Vol.6 No.-

I have studied life of Yoon-Dong-Li(尹東里), who applied Un-Ki(運氣) theory to medicine during Suk-Jong(肅宗) to Jeong-Jo(正祖) in Yi-Dynasty and also studied his existing writings named 《Cho-Chang-kyeol》(草窓訣). The referenced original work prints were based on 1980's pring of Chung-Ku oriental medical society and National Central Library and The academy a korean studies possessed print. Studied with these books, I have concluded as follows. 1. Yoon-Dong-Li(尹東里) courtesy name is Ja-Mi(子美), pen name is Cho-Chang(草窓). He was born in 1705, Suk-Jong(肅宗) 31yrs, and died in 1784, Jeong-Jo(正祖) 3yrs in Yi-Dynasty. He had lineage of third-generationed-doctor and learned medicine from his uncle, Yoon-Woo-Kyo(尹雨敎). His father Yoon-Yi-Kyo(윤이교) gaved him second influence. 2. Confucianal physician in Ming Dynasty You-Bu(劉溥) respected Ju-Ryeom-Kyo(周濂溪), confucianist in Song-Dynasty and You-Bu(劉溥) does not removed grass in front of window (because in chinese, Cho-Chang(草窓) means grass in front of windows), and named himself Cho-Chang(草窓). Yoon-Dong-Li(尹東里) followed this suit so called himself Cho-Chang(草窓). 3. The main contents of 《Cho-Chang-Kyeol》(草窓訣), <Un-Ki-Yeon-Lon>(運氣衍論) was written in 1725, when Yoon-Dong-Li(尹東里) was 21yrs old and printed in 1736. The other part of 《Cho-Chang-Kyeol》(草窓訣), <Yong-Yak-Pyeon>(用藥篇) was written in 1746. These two parts were not written in the same time. The <Un-Ki-Yeon-Lon>(運氣衍論) was written 11years earlier than <Yong-Yak>(用藥). Two parts were combined another day and named 《Cho-Chang-Kyeol》(草窓訣). 4. Existing 《Cho-Chang-Kyeol》(草窓訣) is transcribed printing with the content of "Five elements motion and the six kind of natural factors theory"(五運六氣論). Each edition is generally similar in content, but also has different points each other so naw we hardly finds a complete set of works. 5. 《Cho-Chang-Kyeol》(草窓訣) is a first technical book which treats of Un-Ki(運氣) theory in korea. 6. The contents of <Un-Ki-Yeon-Lon>(運氣衍論) of 《Cho-Chang-Kyeol》(草窓訣) is mechanism of diease according to excess and insuffciency of five elements motion and six kinds of natural factors, and symptoms and priscriptions, includes variated priscriptions. 7. Two parts in <Un-Ki-Yeon-Lon>(運氣衍論) of 《Cho-Chang-Kyeol》(草窓訣), 'Sang-tong'(相通) and 'Kak-Tong'(各通), threats of mechanisim of the disease according to five elements, with the principle of inter-promoting and inter-acting, in the change of ten heavenly stems and five elements motion. 8. In the <Yong-Yak-Pyeon>(用藥篇) of 《Cho-Chang-Kyeol》(草窓訣) describes priscription for clinical application according to Un-Ki(運氣) and also records about misuse of medicine. 9. In the 《Cho-Chang-Kyeol》(草窓訣), most of priscription are common using one, which also found in 《Dong-Ui-Bo-Gam》(東醫寶鑑) and there are few of priscriptions by Yoon-Dong-Li(尹東里).

偏析型 2元系合金의 溶體化末期에 있어서 非平衡第2相의 固溶擧動에 대해서는 아직까지 理論的으로 정립되어 있지 않았다. 本 論文에서는 主로 dendrite element의 境界에 晶出된 非平衡第2相의 유효擴散距離로써 1次arm 間隔을 考慮한 擴散 model인 尹의 近似解에 의해 이들 擧動을 調査하였다. 이를 위해 天然가스등의 輸送材料로 囑望되는 高濃度 Al-8%Mg合金을 사용하였다. 實驗結果, 理論的인 尹의 近似解의 實驗値는 近似的으로 一致되었고, 특히 溶體化末期에서는 完全히 一致됨을 알 수 있다. 結局 從來의 Flemings의 解析値보다 더욱 實驗値에 近似하였다. The solution kinetics of nonequilibrium second phase of a segregated binary alloy in the later stages of solution treatment have not yet been made theoretically clear. This paper attempted mainly to investigate this behaviour by Yoon's approximate analysis given by a simple model based upon primary arm spacing as an effective diffusion distance of the second phase which has crystallized at the boundary of dendrite element. For this purpose, we used the high magnesium Al-8% Mg alloy which is expected to be used for transport of liguified natural gas. The theoretically calculated results are in the approximate agreement with that of experiments for complete dissolution time and solution kinetics (expecially at the later stages) of β-phase. The Yoon's approximate analysis was in better agreement with the present experimental results than the Flemings conventional analysis

H. J. YOON, C. S. YOON, T. S. KIM. The Kinematic Analysis of Peters Motion on Parallel bars. Korean Journal of Sport Biomechanics, Vol. 14, No. 2, pp. 15-26, 2004. The purpose of this study was to investigate the kinematic variables of peters motion in parallel bars. The subjects were 3 male national gymnasts. For this study, kinematic data were collected using video camera. Coordinate data were low-pass filtered using a fourth-order Butterworth with cutoff frequency of 6Hz. Each valuables analyzed was used to compare kinematic features between the subjects. The conclusions were as follows; 1. For a stable regrasp motion, the subjects appeared to increase horizontal and vertical displacement during the DS phase because it induce a vertical elastic of body and reaction of bar for the US phase. 2. For a stable hand standing motion of the regrasp, the subjects appeared to maintain the fast vertical and horizontal velocity during the DS phase, but in contrary during the US and Air phase the vertical and horizontal velocity appeared to do decrease. 3. When the arm lean angle and the trunk lean angle maintain a big angle during the DS phase, the subjects appeared to do a stable performance to release in a high position.

출아효모에서 TAR 클론닝법을 이용한 고등동물의 게놈으로부터 특정 염색체 부위의 분리

박정은,윤영호,이윤주,김광섭,윤세련,안태진,임선희,선우양일 동아대학교 기초과학연구소 2003 基礎科學硏究論文集 Vol.20 No.1

복잡한 게놈 분석에 용이하도록 효모의 인공 염색체(YAC) 클론닝 시스템은 발달되어왔다. YAC은 박테리아의 인공 염색체(BAC)보다 더 큰 단편을 클론닝할 수 있고, 또한 클론된 단편을 쉽게 변형시킬 수 있다. 형질전환과 연계된 재조합법(Transformation-Associated Recombination; TAR)은 게놈 라이브러리를 만들지 않고 직접 게놈 DNA로부터 분리하고자 하는 유전자나 특정 염색체 부분을 클론닝 할 수 있는 방법이다. 이 방법은 spheroplast transformation을 수행하는 동안, 목적으로 하는 유전자의 5' 그리고 3' 염기 배열(hooks)을 지닌 TAR 벡터와 게놈 DNA 사이에서 일어나는 상동성 재조합에 의해 이루어진다. 효모 내의 in vivo 재조합을 이용한 TAR 클론닝법은 복잡한 게놈으로부터 목적의 염색체 부분을 원형 YAC의 형태로서 선택적으로 분리할 수 있다. 그러므로 TAR 클론닝 법은 특정 염색체로부터 YACs을 만드는데 매우 유용하여, 전체 게놈으로부터 특이적 유전자나 유전자의 family를 분리하는데 효과적인 방법으로 사료된다. Yeast artificial chromosome (YAC) cloning systems have advanced the analysis of complex genomes considerably. They permit the cloning of larger fragments than do bacterial artificial chromosome systems, and the cloned material is more easily modified. Transformation-associated recombination (TAR) is a cloning technique that allows specific chromosomal regions or genes to be isolated directly from genomic DNA without prior construction of a genomic library. This technique involves homologous recombination during spheroplast transformation between genomic DNA and a TAR vector that has 5' and 3' gene targeting sequences (hooks). Using in vivo recombination in yeast, TAR cloning selectively isolates, as circular YACs, desired chromosome segments or entire genes from complex genomes. We propose that TAR cloning can provide an efficient means for generating YACs from specific chromosomes and that TAR cloning may be useful for isolating families of genes and specific genes from total genome DNA.

조윤재(Cho, Yoon Jae),백인섭(Paek, In Soub),김종출(Kim, Jong Chool),안태호(Ahn, Tae Ho) 한국서비스경영학회 2021 서비스경영학회지 Vol.22 No.1

With regards to the various project to establish information system in the Korean software market, a company intending to win such project considers comprehensively the business detail, expected profits, and probability to win within available resources and comes to determine if to make an offer. Such judgement is one of the most important decision making affecting the overall business management like sales and revenue. Therefore, when the proposed project portfolio is defined as the composition of the project decided to be offered among the ordered projects, Cho, Yoon-Jae(2020) suggests a mathematical model of the problem of maximizing the sum of expected values in constituting the proposed project portfolio and an optimal solution accordingly. This paper assumes the concept of a project mode to be following: 1) the resources are limited, 2) a linear progression of the probability of the orders to be awarded as the duration of each activity increases, 3) the nature of the proposed project is reflected. Unlike previous studies, this research proposes a heuristic technique as a solution to the composition of the proposed project portfolio. The simulation in this study verifies the effectiveness and efficiency of the proposed algorithm as well.

이범석,강윤구,윤태호,국윤아 대한치과교정학회 2007 대한치과교정학회지 Vol.37 No.5

이 연구는 한국인 여자 유명 모델과 일반인의 정면입술의 차이점을 비교하여 아름다운 입술의 특징을 규명하며 양악 전방 분절골절단술을 시행한 환자에서 정면입술의 변화를 측정하고 그 수술 결과를 한국인 모델과 비교하여 차이점을 알아보고자 하였다. 한국인 유명 모델 30명, 일반인 26명과 양악 전방 분절골절단술을 받은 환자의 10명을 대상으로 정면입술 부위의 12개의 선 길이, 홍순의 5개의 각도와 둘레 및 면적을 측정하였고, 통계분석은 unpaired & paired t-test를 이용하였다. 한국인 유명 모델 군과 일반인 군의 비교에서 하안면 얼굴 폭경, 하안면 수직길이, 상홍순의 높이, 하순의 길이, 상홍순의 구각부 각도와 central bow의 각도는 의미 있는 차이로 일반인 군보다 유명 모델 군에서 작았다. 그러나, 입술의 폭, 하홍순의 높이, Cupid's bow tip간 거리와 하홍순의 구각부 각도는 유명 모델 군에서 컸고 입술의 둘레와 전체 면적에서도 일반인 군보다 컸다. 양악 전방 분절골절단술을 받은 환자의 정면입술에서는 하안면 얼굴 폭경, 상홍순의 높이, Cupid's bow tip에서 구각부까지의 길이와 상홍순의 면적이 통계적으로 의미 있는 변화를 보였고 한국인 유명 모델과의 비교에서 비슷한 수치를 나타내었지만 상순의 길이는 반대로 증가하였다. 연구의 결과는 교정치료 혹은 양악 전방 분절골절단술을 계획할 때 정면 입술 심미성을 평가하는 데 도움이 될 것으로 생각된다. Objective: The aim of this study was to determine firstly the characteristics of esthetic lips in Korean females and secondly to measure the changes of the lips before and after anterior segmental osteotomy in bimaxillary protruded patients. Methods: Samples consisted of 30 models and 26 nonmodels, and 10 patients who had received anterior segmental osteotomy. Twelve linear measurements, 5 angular measurements, and the lip perimeter and area were measured. These results were compared for each group using unpaired and paired t-tests. Results: Full face width, nose to chin, upper vermilion height and angle, lateral heights at the point of the tips of Cupid's bow, central bow angle, and the lower lip to chin lengths were significantly greater in nonmodels than in models. However, overall lip width, lower vermilion height and angle, tip-to-tip of Cupid's bow lip perimeter, and lower vermilion area were greater in models than in nonmodels. Comparison of before and after anterior segmental osteotomy revealed that the values for the upper vermilion and lateral heights, the angle to Cupid's bow tip lengths, and upper vermilion area of post-operative patients had become similar to those of Korean female models. Our findings demonstrated that Korean female models have a fuller lower vermilion & thinner upper vermilion compared with nonmodel controls, as determined by the vermilion heights, angles, and areas. Conclusions: It will be helpful for clinicians to use these measurements as guidelines for improving patients' facial esthetics.
