본 연구는 밤나무 교잡종 과실의 조합별 및 개체별 질적특성을 조사함으로써 신품종 육성의 기초 자료뿐만 아니라 품종검정 기준설정의 기초자료로 활용하는데 그 목적이 있다. 과실모양은 11 조합의 많은 개체에서 타원형(85.30%)을 나타냈으며 K×R 등 5조합에서 삼각형(3.78%), R×K 등 8조합에서 원형(5.46%), R×O 등 3조합에서 장타원형(5.46%)으로 각각 관찰되었다. 과피색은 모든 조합에서 암갈색과 적갈색이 각각 49.16%와 38.24%로 관찰되었으며 과피털은 K×R과 R×K만이 과피 전체에서 각각 1개체씩 관찰되었다. 과피털의 밀도는 대부분의 조합에서 92.86%가 중 이상이었으며 좌면의 크기는 E×O, E×R, K×O에서만 중 이상인 것으로 조사되었다. 과실의 광택은 K×O조합에서만 약인 개체가 출현하였으며 열과형태는 모든 조합에서 3가지 형태중 2가지 이상의 형태가 각각 혼재되어 있었다. 양적형질이 우수한 8개체 중 RO-22, RO-25 등 2개체만이 과실모양과 과피색이 각각 장타원형과 암갈색을 나타내었으며 OK-2 제외한 나머지 5개체는 각각 타원형과 적갈색으로 관찰되었다. 과피털의 위치는 OK-2 제외한 모든 개체는 과정부였으며 과피털의 밀도는 IO-15 제외한 모든 개체에서 밀하게 분포하였다. 좌면의 크기는 JO-7과 RO-25 개체가 가장 작았으며 광택은 K×O의 1개체를 제외한 모든 개체에서 중 이상으로 우수하였다. 열과형태는 JO-7과 JO-12, IO-15, OK-15 개체에서 각각 과정부 열과와 주두부 열과 등 각각 단일 형태를 나타낸 반면, OK-2 등 4개체는 과정부 열과와 측면부 열과가 혼재하고 있음을 알 수 있었다. 내피박피성을 조사한 결과, OK-2, OK- 4, OK-15 등 3개체는 내피박피율이 20% 내외로 불량한 반면 RO-25, JO-12 등 2개체의 내피박 피율이 각각 78.6%, 72.4%로 매우 우수한 것으로 나타났다. This study was aimed to applicate as the basic data for the presentation of International Union for the Protection of New Varieties of Plants (UPOV) guideline and for breeding new cultivars through qualitative characteristics of nut in chestnut hybrids. In nut shape, oval type, 85.30%, could be observed in all combinations, and triangle type, 3.78%, in K×R, K×O, E×R, I×R, J×O, and oblong type, 5.46%, in R×O, I×O, E×O, I×R, respectively. Both dark and reddish brown, 49.16% and 38.24%, in nut color were observed in all combinations, and nut pericarp hairs in only K×R, R×K could be observed in whole part. The density of its hair showed above middle rank (92.86%) in most of combinations, and the size of hilum area showed above middle rank in only E×O, K×O and E×R. Ten combinations except K×O showed a good condition in nut luster, and two or three types of three split type could be observed in all combinations, simultaneously. Superior individuals, RO-22 and RO-25, showed oblong and dark brown, but others except OK-2 showed oval and reddish brown in nut shape and nut color, respectively. In position of nut pericarp hair, only OK-2 showed stigma part, but all of superior individuals except IO-15 showed thickness in its density. Only JO-7 and RO-25 were smaller than others in size of hilum area, and JO-7, OK-4, OK-15, RO-22 and RO-25 had nuts with excellent luster. Most of individuals had nuts with two or three types in type of nut split, and JO-7, JO-12, IO-15 and OK-15 showed only single type. In peeling rate, OK-2, OK-4 and OK-15 showed around 20% while RO-25 and JO-12 showed 78.6% and 72.4% being considered as superior individuals for roasted chestnuts.

국립중앙박물관은 용산 새 박물관의 전시 유물로 선정된 중앙아시아 벽화의 연차적인 보존처리를 위해 “독립행정법인 일본 도쿄문화재연구소’’와 공동연구를 모색하게 되었다. 2001년에 본4074, 본4096 작은 벽화편 2점의 보존처리를 시작하면서 벽화의 균열 박락 등 손상상태, 구조와 구성재료, 이전 보존처리에서 적용된 재료와 방법에 대한 기초조사를 실시하였다. 조사결과 본4074, 본4096 2점의 벽화는 흙과 지푸라기를 반죽하여 만든 벽체에 석고를 발라 바탕으로 하고 그 위에 채색을 한 것으로 나타났으며 벽체 속에 포함된 지푸라기의 방사선 탄소연대측정 결과 본 벽화는 10세기 말에서 13세기 초에 만들어진 것으로 나타났다. 또한 X-선회절 분석 결과 화면의 흰색 바탕은 gypsum[Ca(SO₄)·2H₂O]과 CaSO₄, Calcite(CaCO₃)가 적색계통은 연단(鉛丹:Pb₃O₄)과 led arsenate[Pb(As₂O₆)], 녹색계통은 Cuprite(Cu₂O)와 arsenolite(As₂O₃), arsenic oxide(As₂O₄) 등이 사용된 것으로 조사되었다. This article is about a joint project carried out by the National Museum of Korea and the Tokyo Cultural Properties Research Institute for the conservation of central Asia Wall painting that has been selected for the exhibition at the new Seoul National Museum of Korea at Yongsan. The investigation of the wall painting revealed very useful information. This includes the condition of the object, and the identification of evident damage, such as cracks, loss of pigment, plus materials and methods employed during the object's creation, as well as previous conservation treatment. The object was mainly made by applying plaster to the body (wall) that consisted of a mixture of soils and rice straws. Then, on the surface of the wall-painting, pigments were used to draw and to colour it. As a part of the investigation, radiocarbon dating was conducted using straw samples taken from the object. The result indicates that the object is probably dated form between the end of the 10th Century and the beginning of the 13th Century. The result of X-ray diffraction also revealed the composition of the pigments used on the surface. These are 1. gypsom[Ca(SO₄)·2H₂O], CaSO₄ and Calcite(CaCO₃) and Calcite(CaCO₃) that were used for the white background. 2. Pb₃O₄ and led Arsenate [Pb(As₂O₆) that were used for the red colouring. 3. Cuprite(Cu₂O), Arsenolite(As₂O₃) and Arsenic Oxide(As₂O₄) that were used for the green colouring.

Massive hemoptysis represents a major medical emergency that is associated with high mortality. The causes of hemoptysis are various and include pulmonary and cardiovascular disorders and trauma. The causes of pulmonary disorder are tuberculosis, bronchiectasis, abscess, malignancy, bronchitis, and fungal infection. The causes of cardiovascular disorder are mitral stenosis, pulmonary embolism, and congestive heart failure. A fistula between an aortic aneurysm and the pulmonary parenchyma is one of the causes of hemoptysis, but it is a rare. However, if undiagnosed, it is a uniformly fatal cause of massive hemoptysis. This is a case of bleeding from a fistula between an aortic arch aneurysm and a lung parenchyma in a patient with an aortic arch aneurysm who presented with massive hemoptysis. He had suffered intermittent hemoptysis since he was diagnosed with an aortic arch aneurysm three years before. A high clinical suspicion must be maintained when a history of intermittent hemoptysis is obtained in patients with an aortic aneurysm or prior aortic graft surgery.

The Purpose of the Study was to determine whether the glutamate ingestion prior to exercise would reduce the lactat formation and its clearance in exercising mscle tisue during Submaximal and maximal execise. Six elite distance rummers particapated in this study. The Subjects had a half dose of glutamale(15.6mg .Kg?? ??) at 45min and ingested rest dose at prior to exerise. The test Performed twice. One was Performed in the track and the other was in the Lab. Blood Smples were obtained from catheter which was placed in the antecubital vein (Lab test) and finger tip Samples (Feld test) Unaltered blood lactate was observed in both trials, but, tended to less lactate concentration with glutamate ingestion than that of without glutamate ingestion. The recovery rate of blood lactate was markely rapid with glutamate ingestion in the field test. Unchanged in heart rate was founded in both trials. It many Suggest that, the additional supplement st of glutamate can improve execise performance limiting lactate formation or induce its rapid clearance from the muscle fissue.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.
