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.

This paper is a study on how critical terms has been discussed and converged in the early modern Korean literary circles. For this study, I focused on the concept of ‘description’ in the debate between Yum, Sang-sub and Kim, Dong-in. In order to re-examine this debate, productive intent is necessary. The countless signs of misunderstanding which was found in those texts is related to the confusion about the concept of terms. It is the general situation of early modern literary circles rather than a matter of Yum and Kim. They had trouble applying western literary theory in Korean language. This paper noted the ‘description’ among several critical terms, because it was the very hot issue of the early modern novel criticism. Yum and Kim emphasized description concept associated with essential attributes of ‘New’ literature like other critics. But the concept of description they thought is different from each other. Kim preferred to describe concisely by grasping the essence of the target, compared to Yum preferred detailed and rich description. It should be noted that they tried to create novel texts in order to show their own concept of description than to explain a theory. Because this debate may be interpreted as the main motivation producing major legacy of the history of early modern novels.

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.

In this paper, the effect of oxygen component in fuel on the exhaust emissions has been investigated for a direct injection diesel engine. It was tested to estimate change of engine performance and exhaust emission characteristics for the commercial diesel fuel and oxygenated blended fuel which has seven kinds of mixed ratio. And, the effects of exhaust gas recirculation(EGR) on the characteristics of NO_x emission have been investigated. Ethylene glycol mono-n-butyl ether(EGBE) contains oxygen component 27% in itself, and it is a kind of effective oxygenated fuel of mono-ether group that the smoke emission of EGBE is reduced remarkably compared with commercial diesel fuel, that is, it can supply oxygen component sufficiently at higher loads and speeds in a diesel engine. It was found that simultaneous reduction of smoke and NO_x was achieved with oxygenated fuel and cooled EGR method.

최윤정,이학주,이성숙,최돈하 한국목재공학회 2003 목재공학 Vol.31 No.1

항균활성이 우수한 혓개나무 목부 에탄올 조추출물로부터 7종의 화합물을 단리하였으며, 기기분석 결과 flavonoid인 5-hydroxy-7methoxyflavone를 비롯하여 5,7-dihydroxyflavone (chrysin). 5,7-dihydroxyfla-vanone(pinocembrin), 3,5,7-trihydroxyflavanone (pinobanksin), 3,4',5,7-tetrahydroxyflavanone (aroma-dendrin)과 stilbenoid인 3-hydroxy-5-methoxystilbene과 3,5-dihydroxystilbene (pinosylvin)으로 각각 동정되었다. 이들 단리물질에 대한 항균활성을 조사한 결과 stilbenoid인 3-hydroxy-5-methoxystilbene이 공시균주의 생장을 완전히 저해하여 단리물질 중 활성이 가장 높은 것으로 나타났다. 그 다음이 pinocembrin과 pinosylvin으로 Cryphonectria parasitica, Trametes versicolor, Tyromyces palustris 그리고 Trichoderma viride에 대한 높은 균사생장억제율을 나타내어 활성이 우수한 것으로 나타났다. 그러나, flavonoid인 pinobanksin, 5- hydroxy-7-methoxyflavone, chrysin, 그리고 aromadendrin은 항균활성이 낮은 것으로 나타났다. 이상의 결과, 헛개나무 목부 에탄올 조추출물의 높은 항균활성은 3-hydroxy-5-methoxystilbene과 pinocembrin, 그리고 pinosylvin에서 유래된 것으로 사료되었다. Antimicrobial activities of plant extractives were investigated to develop a natural fungicide. Two stilbenoids and five flavonoids were isolated from wood extractives of Hovenia dulcis (Rhamnaceae) which had been selected due to its high antifungal activity among the tested species. The chemical structures of isolated compounds were determinded as : 5-hydroxy-7-methoxyflavone, 5,7-dihydroxy-flavone (chrysin), 5,7-dihydroxyflavanone (pinocembrin), 3,5,7-trihydroxyflavanone (pinobanksin), 3,4',5,7-tetrahydroxyflavanone (aromadendrin), 3-hydroxy-5-methoxystilbene and 3,5-dihydroxystilbene (pinosylvin) on the basis of Mass and NMR spectroscopic data. According to the results of antifungal test, 3-hydroxy-5-methoxystilbene was evaluated as the strongest antifungal compound among the tested compounds and next were pinocembrin and pinosylvin, but those also had high hyphal growth inhibition activities against C. parasitica, T. versicolor, T. palustris and T. viride. However, pinobanksin, 5-Hydroxy-7-methoxyflavone, chrysin and aromadendrin showed very low antifungal activity. In this regard, it could inferred that high antifungal activity of wood extractives of H. dulcis were derived from 3-hydroxy-5-methoxystilbene, pinocembrin and pinosylvin, respectively.

Objectives Mindfulness-base cognitive therapy (MBCT) has been used to treat patients with depression to prevent relapse. The purpose of this study was to examine the effectiveness of Mindfulness-Base Cognitive Therapy for patients who suffer with generalized anxiety disorder or panic disorder for 1 year. Methods 19 patients with generalized anxiety disorder or panic disorder were assigned to receive MBCT for a period of 8 weeks. The Hamiltion Anxiety Rating Scale (HAM-A), the Hamilton Depression Rating Scale (HAM-D), the Beck Anxiety Inventory (BAI) and the Beck Depression inventory (BDI) were used at 0 weeks, 8 weeks and 1 year to assess the results. Results MBCT demonstrated significantly decreases on all the anxiety scale scores (HAM-A, p=0.00 ; BAI, p=0.00) and depressive scale scores (HAM-D, p=0.99 ; BDI, p=0.00). The patients who received 8-week of MBCT showed a higher remission rate (15/19, 78%) during the 1-year follow-up period. Conclusion MBCT may be effective at relieving the anxiety and depressive symptoms of patients who suffer with generalzed anxiety disorder or panic disorder for 1 year. However, further well-designed controlled trials are needed to assess the value of MBCT.

This study investigated the relationship between PCK (Pedagogical Content Knowledge) and pre-service mathematics teachers' mathematical beliefs, and the effects of PCK on their teaching. The data were collected through pre & post interviews, a questionnaire, and classroom observations of six pre-service mathematics teachers who were taking their field practica in their senior year. The results indicate that the pre-service mathematics teachers' differing beliefs about the nature of mathematics affected their PCK. This study showed the relationship between their beliefs about teaching and the learning of mathematics and PCK. It is recommended that more opportunities for PCK development, as well as for modifications in of their beliefs have to be offered in education programs for pre-service mathematics teachers. 본 연구의 목적은 예비수학교사들의 수학적 신념과 수업에서 발현된 교수학적 내용지식(PCK)의 특징을 알아보고, 이를 통해 수학적 신념에 따른 PCK의 관련성에 대해 분석하는 것이다. 이 연구는 교육실습 중인 예비수학교사 6명을 대상으로 실시한 PCK 설문지, 인터뷰 자료, 수업관찰 자료를 분석하는 질적 연구 방법을 토대로 하였다. 연구결과, 예비수학교사들의 다양한 수학 본질에 대한 신념은 PCK에 서로 다른 영향을 주었으며, 수학 교수-학습에 대한 신념과 PCK사이에는 밀접한 관련성이 있음을 볼 수 있었다. 따라서 신념과 교수학적 내용지식(PCK)을 함께 발달시킬 수 있는 예비교사 연수 및 지원 프로그램의 확충이 필요하다.
