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.

We studied the effect of mass transfer in a dryer on the condensation of amino resin mould material and the curing characteristics, and investigated the drying rate, the moisture and the curing fluidity according th the variations of the temperature and the drying media recycle volume which affects the mass transfer in the drying process. So, the result are summarized as follows: ① As the drying temperature increased to 70℃, 80℃ and 90℃ respectively, the drying rate became fast. ② In the same final drying time, the higher the drying temperature became, the more the moisture content of the urea resin mould material inceased. ③ Accordingly as the drying temperature increased, the moisture content of the drying material suddenly decreased in short drying time, but the moisture content increased when the drying time was between 80 minute and 120 minutes. ④ As the drying temperature increased, the curing fluidity of amino resin mould meterial decreased. ⑤ As the recycle volume of the drying media increased, the curing fluidity decreased.

최성진,홍성연 고신대학교 자연과학연구소 2006 고신대학교 자연과학연구소 논문집 Vol.13 No.-

이 연구에서는 여러 가지 alkane,alkene,및 alkyne 화합물의 이온화 에너지를 양자역학적 방법으로 계산하였다. 분자의 구조와 에너지를 구하기 위한 양자 역학적 방법으로는 Hartree-Fock(HF) 방법과 Density functional theory(DFT)에 의한 방법을 사용하였으며 Koopmans' theorem을 이용한 방법과 adiabatic 방법으로 이온화 에너지를 계산하여 실험값과 비교하였다. 이 연구에서 조사한 모든 화합물에 대해 DFT 방법으로 구한 adiabatic 이온화 에너지가 실험값과 가장 일치하였으며 π-전자를 갖는 alkene이나 alkyne 화합물에 대해서는 HF 방법으로 구한 Koopmans 이온화 에너지도 매우 좋은 결과를 보였다. 이들 화합물의 이온화 에너지는 탄소 사슬이 길어짐에 따라 곧 포화되어 alkane 화합물의 경우 탄소의 수가 6이상,π-전자를 갖는 alkene이나 alkyne 화합물의 경우 탄소의 수가 3이상이면 거의 포화되는 것을 보이고 있다. Ionization energies of a variety of alkanes/ alkenes, and alkynes were computed through quantum-mechanical methods in this study. The Hartree-Fock(HF) method and the Density functional theory(DFT) were applied to obtain geometrical structures and energies of the molecules. The ionization energies were calculated using Koopmans's theorem and the adiabatic method, respectively, and cornpared with the experimental values. The adiabatic ionization energies computed through DFT calculations show excellent agreements with the experimental ones for all the molecules in this study. Also, for π-electronic systems such as alkenes and alkynes, the Koopmans' ionization energies estimated through HF calculations are in good agreement with the experimental ones. The ionization energies of the molecules are saturated with the chain lengths of the molecules; the saturation lengths being greater than 6 carbon atoms for alkanes, and 3 carbon atoms for π-electronic systems such as alkenes and alkynes.

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.

The purpose of this study is to understand the essence of the current serious state of athletic injuries of Tae-gweon-do athletes in middle schools. We referred to books on injuries and then circulated a questionnaire of 25 items related to 4 fields; athletic injuries, causes and the times of the injuries, treatment of the injuries, and advance information about the athletic injuries. We converted the actual numbers into a percentage in order to analyze and treat each item as a statistic. The results were as follows: 1. ATHLETIC INJURIES 1) Skin Injuries 56 athletes(88.89%) had suffered skin injuries during the matches or practices. The skin injuries had the largest number of the responses in the questionnaires. Four athletes had suffered from blisters(6.35%), 2 athletes from dislocated fingers and toenails(3.17%), and only 1 athlete(1.59%) suffered from no injuries 2) Injuries to Muscles or Tendons The number of the athletes who had suffered contusions to the muscles or tendon were 32(50.79%) and 1 athlete(1.59%) had suffered from muscular convulsions. The other 8 athletes(12.7%) had not suffered any skin injuries. 3) Injuries to bones 28 athletes(44.44%) had suffered fractures to their bones and had the highest incident rate, 15 athletes(23.81%) had suffered luxate, and 1 athlete(1.59%) from osteomelitis. There were 18 athletes(28.57%) injury free. 4) Injuries to the Joints The largest number of joint injuries were sprains ; 27athletes(42.86%) gave the formative responses to the questionnaires. The number of the luxate injuries were second - 21 athletes(33.33%), 3 athletes had suffered injuries to the cartilage in their backbones(4.76%), 12 athletes had not suffered any injuries to the jounts(19.05%) 5) Injuries to the Nerve or sense organs 57 athletes(87.30%) gave negative answers to these questions. They were the most number. 4 members admitted that they had suffered consussions(6.35%) and 2 athletes(3.17%) had suffered some troubles to their eyesight. 1 athlete(1.59%) had suffered hearing trouble, and nerve palsy. 2. THE CAUSES AND TIMES OF ATHLETIC INJURIES 1) The Causes of Athletic Injuries 24 athletes(38.10%) had been injuied by opponents' or rivals' illegal moves in the middle of the matches. And 17 athletes(26.98%) had been injured due to their own carelessness. Three athletes(20.63%) suffered injuries due to their insufficient warm up. Five players(7.94%) had been injured under situations that were beyond any control. Two athletes(3.17%) due to fatigue or exhaustion. One answered to the questionnaire showed us that One player's(1.59%) injured. 2) THE TIMES OF INJURIES OUTBREAK 27 athletes(42.86%) showed that they had been injured while they were practicing their skills. These responses were the most. Fifteen athletes(23.81%) had not been injured at any time. 11 athletes(17.46%) replied that they had been injured right after the matches. 5 athletes(7.94) in the middle off their private practice, and 3 athletes immediately after their practices. And 1 athlete replied that he had been injured when his practice reached its peak. The most athletes - 27 athletes(42.86%) - had been injured at the places of practice matches. Whereas. 15 athletes(23.81%) had not been injured at any place. 14 athletes(22.22%) at the regular sports facilities. 5 athletes(7.94%) at the physical training centers, and the other 2 athletes at some other practice facility(3.17%) 3) Thirty-seven athletes - the most athletes(58.78%) - had been injured while practicing because they chose to begin their practices again. Instead, 26 athletes were injury free(41.27%) Especially, 30 athletes(81.09%) had been more seriously injured than before after they began practising again. 5 athletes(13.5%) suffered worse injuries from their own. But the other 2 athletes reported that their injuries did not increase. 4) The questionnaire showed us that the weather had a role in the injuries to the players. 36 athletes(57.14%) - the highest number - had been injured when it was cloudy. Eleven athletes(17.46%) when rainy, 9 athletes(14.29%) when the weather was clear, and 2 athletes(2.17%) when snowy while 5 athletes(7.94%) had not been injured under any special weather condition. Winter seemed to be the worst season for the athletes. More than half the players answered the questionnaires - 42 athletes(66.67%) - had been injured in the season. And then 17 athletes in summer(26.9%), in spring 3 athletes(4.76%), and only 1 athletes(1.59%) was unlucky. During the day, the afternoon practice was most dangerous. The incident rate was the highest - 57 athletes(80.95%) were misfortunate to be injured while only 8 athletes(12.07%) were not injured. At night, 3 athletes(4.75%), and in the early morning only 1 athlete(1.59%) had suffered from an injury. 3. THE TREATMENT OF ATHLETIC INJURIES 1) The First-aid Treatment of Injuries For the first-aid treatment, using a spray that was the most numerous - 55 athletes had used it(87.30%). And 7 athletes(11.11%) had have themselves massaged with mansoradam. Using it was next in order of numbers. The questionnaire investigation showed only one athlete had used a bandage to have their injuries treated. 2) First-aid treatment The most number of the athletes had been given their first-aid treatment by their trainers or coaches - 48 athletes(76.19%) By their team-mates, 12 athletes(19.05%) For themselves, 3 athletes(4.76%). 3) 32 athletes(50.08%) had been treated with physiotherapy below 10 times, and it was the first in order of numbers. 6 athletes(9.52%) had been treated between 11 times and 20 times. Instead, 25 athletes(42.86%) had not been treated with any physiotherapy. The result showed that 31 athletes had their swelling reduced(81.58%), 4 athletes found out that their pain had stopped(10.53%) while 2 athletes replied that the state of their swelling had not changed (5.26%). Therapy had little effect on 1 athlete's swelling. 4) The most numerous students - 35 athletes(55.55%) eave negative answers to the questionnaire if they had ever been treated with oriental acupuncture. They said they had never. 10 athletes had been treated with the Oriental acupuncture within 10 times, and 1 athlete(1.59%) above 11 below 20 times. The result of the treatment showed that the swelling was gone in 25 athletes(89.29%), and the pain had stopped in 2 athletes(7.14%) while 1 player answered that the Oriental therapy had failed to reduce his swelling. Respondents(50.79%) thought that the physiotherapy had been the most effective, 32 , and 25 athletes replied that the acupuncture and moxibustion had been more effective then other treatments. 4 athletes(6.35%) preferred hospital treatment. And 1 respondent answered he liked to pass or ointment while another like massage better(each 1.59%), as reported on the questionnaire. 4. ADVANCE INFORMATIONS OF ATHLETIC INJURIES 1) Thrity-two respondents(50.79%) recognized that informations or theories about athletic injuries, and, especially, 27 athletes conformed that they were absolutely necessary(42.86%). 3 respondents(4.70%) said they are helpful to some degree. Instead, 1 player responded that they were of no use. Fifty-seven athletes said that they had never heard about the information or theories(90.79%), and that they were the first in the order of numbers. 6 athletes(9.52%) had heard about them once a year. 2) In order to prevent themselves against the athletic injuries, 19 athletes had increased the duration of their warming-up time(30.19%), and that was the first in the order of numbers. Eleven respondents said they had tried to relax themselves(17.46%). While 7 athletes had tried to prevent injuries through improving their athletic facilities or reinforcing them(11.11%). 6 athletes had tried to focus their attention on their practice or matches(9.52%). Five athletes had used their team doctors or medical personnel(7.94%), and 4 athletes had used the their physical examinations regularly (6.35%) Improving of coaching methods had been useful to 3 athletes(4.76%), or having a good meal had also been helpful to 2 athletes(3.17%), Another 2 athletes had tried to recover from their fatigue(3.17%) to escape from fear of their injuries. Reducing the duration of the practice had been also useful for 1 athlete(1.59%). And another athlete had tried to improve his skills to keep himself safe.
