This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10%, while germination rate of seeds collected in 2004 was above 90%. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4×4×5cm(length×width×height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

면외변위의 정량적 계측을 위한 ESPI와 Shearography의 비교

최정구,김경석,장호섭,정성욱 朝鮮大學校 機械技術硏究所 2005 機械技術硏究 Vol.8 No.2

Electronic Speckle Pattern Interfrometry is a common method for measuring out-of-plane displacement and in-plane displacement and applied for vibration analysis and strain/stress analysis. However, ESPI is sensitive to environmental disturbance, which provide the limitation of industrial application. On the other hand, Shearography based on shearing interferometer can directly measure the first derivative of out-of-plane displacement, which is insensitive to vibration disturbance. This paper proposes the out-of-plane displacement extraction technique from results of Shearography by numerical processing and measurement results of ESPI and Shearoraphy are compared quantitatively.

Choi,Seong-Kyu,Yun,Kyeong-Won,Chon,Sang-Uk,Seo,Young-Nam,Seo,Kyoung-sun,Kwon,Byung-Sun 한국자원식물학회 2003 Plant Resources Vol.6 No.3

This study was conducted to produce effectively more leaves of Angelica acutiloba through year-round production system by using various mulching materials and polyethylene(PE) tunnel. Soil temperature by covering treatment was higher in PE mulching and PE tunnel than in rice straw mulching, especially showing the highest temperature in PE tunnel from April through May. Water content of soil was higher in PE mulching than in non-mulching. Leaf production of Angelica acutiloba through year-round production showed the highest in PE tunnel and root production in PE mulching. These results suggest that leaf production of Angelica acutiloba can be maximized through PE tunnel cultivation system.

최의성,박경진 충북대학교 의과대학 충북대학교 의학연구소 1997 忠北醫大學術誌 Vol.7 No.2

경골과 골절로 치료받은 17예의 환자를 대상으로 골절의 유형, 치료 방법, 정복의 정도, 골이식의 방법 및 동반 손상의 유무 등을 중심으로 치료 결과를 분석하여 예후에 영향을 미치는 인자를 조사하고자 하였다. 경골 외과의 분리 또는 설상형 골절의 제 1형이 가장 많았으며, 13예에서 수술적 정복 및 내고정이 시행되었다. 88%의 환자에서 만족할 만한 결과를 얻었는데, 동반 손상은 수술적으로 치료되었고, 결과에는 큰 영향이 없는 것으로 생각되었다. 경골과 골절에서 예후에 가장 영향을 미치는 인자는 골절의 정복 정도인 것으로 생각되었으며, 정확의 방법이나 고정 기간은 크게 문제되지 않았다. 5mm 이상의 관절면 불일치는 불만족한 결과를 초래하였다. 골이식과 만족한 결과와는 상관 관계는 보이지 않았으나, 큰 골 결손이 있는 경우 골이식은 꼭 필요할 것으로 생각되었다. Seventeen patients with fractures of the tibial plateau were reviewed and assessed in terms of fracture type, treatment method, adequacy of reduction, type of bone graft, associated ligamentous and meniscal injury, and overall result in an attempt to define factors important in the prediction of outcome. Cleavage or wedge-type fractures of lateral condylar plateau(type I) were the most common(29%). Thirteen of the 17 fractures were treated by open reduction and internal fixation, and three were treated by closed methods. Overall, 88% of the patients had a satisfactory result. Ligamentous and meniscal injuries were treated surgically and did not influence the final outcome. The single most important factor in predicting outcome in a patient with a tibial plateau fracture was the adequacy of reduction. The method of achieving the reduction and the length of the immobilization period of the knee were not as crucial. A residual step of greater than 5mm on the weight-bearing area was universally associated with an unsatisfactory result. Even there was no correlations between the satisfactory result with bone graft, bone graft to the large bone defect of tibial plateau fracture is seemed mandatory.

서정성,최광주,나경수,조남수 조선대학교 부설 의학연구소 2002 The Medical Journal of Chosun University Vol.27 No.1

ackground and Objective: This study was designed to compare the IOP decreasing effect between the IOP decreasing effect of patients who were treated with 0.5% Timolol and 2% of Dorzolamide and that of patients who were treated with Cosopt® only being the patients who couldn't be controlled by Timolol adequately. Materials and Method: Twenty eight open angle glaucoma patients, 40 eyes, who weren't able to reach desirable IOP when treated with 0.5% Timolol, were tested. The patients were divided into two groups. In group A 13 patients, 20 eyes, were treated with Timolol and 2% Dorzolamide. In group B 15 patients, 20 eyes, were treated with Cosopt® only. The IOP and side effects were recorded after The 1st week, the 1st month and the 3rd month. Results: After 3 months, the IOP in group A was decreased by 20.5% (4.0mmHg) from 19.5mmHg to 15.5mmHg and the IOP in group B was decreased by 23.7% (4.7mmHg) from 19.8mmHg to 15.1mmHg. There was no statistical significance between the two groups. Conclusion Cosopt® has a similar IOP decreasing effect with that of 0.5% Timolol and 2% Dorzolamide combined. It may increase adaptation of patients by decreasing the number of dispensions.

김경희,권성범,신용섭,최세진 충남대학교 의과대학 지역사회의학연구소 1995 충남의대잡지 Vol.22 No.1

We selected at random 30 geriatric patients who had received operation under the general anesthesia with endotracheal intubation. The patients were divided into 3 groups. Group 1 (control) had received endotracheal intubation without diazepam and lidocaine. Group 2 had received endotracheal intubation with diazepam. Group 3 had received endotracheal intubation with lidocaine. The changes of arterial blood pressure and pulse rate, and the appearance of arrhythmia were compared in each group. The results were as follows : 1. The increase of blood pressure and heart rate were less in group 2, 3 than the control group which showed significant increase of blood pressure and heart rate with endotracheal intubation. 2. The incidence of arrhythmias with endotracheal intubation was less in group 2(20%), group 3(50%) than the control group(80%). 3. The electrocardiographic change in the group 2 and 3 were not significant compared to group 1(control).
