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.

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.

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.

최영환,도남용,나한조,이도용,노용훈,김완수,최종선 조선대학교 2001 The Medical Journal of Chosun University Vol.26 No.2

Background and Objectives : When p53 cancer suppressor gene, occurs gene deletion or point mutation, malignancy develops by loss of p53 function with abnormal p53 protein. The Epstein-Barr virus (EBV) is the causative agent of certain type of lymphoma and undifferentiated nasopharyngeal carcinoma. However, the role of EBV as a causative factor in other head &eck tumors is not fully elucidated except nasopharyngeal carcinoma. This study, the author examined that p53 expression and detection rate of EBV correlate to development of laryngeal and hypopharyngeal squamous cell carcinoma(SCC) and play the possible role of prognostic indicators. Materials and Methods : Formalin-fixed, paraffin-embedded tissue specimen from 32 cases of larynx and hypopharyngeal squamous cell carcinomas were studied by immunohistochemical staining for p53 and EBV. The results of analysis were compared with clinicopathological parameters. Results : p53 expression was 56.3% (18 cases) and the detection rate of EBV was 43.6% (14 cases) of 32 cases in laryngeal and hypopharyngeal squamous cell carcinomas. p53 expression was correlate with histologic grade (p<05) only. Detection of EBV was not correlate with clinicopathological parmeters. Conclusion : These results suggest p53 expression and the detection of EBV may be related with development of laryngeal and hypopharyngeal squamous cell carcinoma. And, the expression of p53 protein can be used as a prognosticator in laryngeal and hypopharyngeal squamous cell carcinoma under certain limitation.

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.
