This paper was carried out to analyze the variation of composition of seed oil with storage periods. Difference of content of crude fat in fresh-cut seed and one year storage seed is not detected but in pentadecanoic acid, acid value, iodine value and peroxide value in one year storage seed have lower than those of the fresh-cut seed. Linoleic acid and oleic acid were high among of total fatty acid in fresh-cut seed but moiety of linolenic acid and icosanoic acid was low otherwise that of palmitic acid and oleic acid is increased in one year storge. In neutral lipid, capric and mytistic acid were high in fresh-cut, oleic acid, palmitic acid and linoleic acid were increased after one year storge. In glycolipid, the lauric acid and linoleic acid were high in fresh-cut seed, the palmitic acid was increased, otherwise, linolenic acid was decreased after one year storge. In phospholipid, palmitic acid and unknown part were high in fresh-cut seed, palmitic acid, oleic acid and linolenic acid were increased after one year storge.
K이 흡착된 Si(111)7×7표면에 대한 RHEED 연구
박종윤,이순보,이경원,안기석,신익조,강건아 성균관대학교 1990 論文集 Vol.41 No.2
상온 및 200℃∼600℃의 Si(111) 7×7 표면에 칼륨(K)을 증착하였을 때의 표면격자구조 변화를 RHEED로 관측하였다. K 증착시 Si(111)7×7 기판의 온도가 상온인 경우, 어느 일정한 증착시간(포화덮임률에 도달했다고 추정되는 증착시간)이 지난 후에는 원래의 깨끗한 Si(111)7×7 패턴과 유사한 Si(111) 7×7-K 패턴이 관측되었고, 증착시간을 증가시켜도 RHEED 패턴은 변화하지 않았다. 이것을 annealing하면 350℃까지는 RHEED 패턴에 변화가 없다가 그 이상의 온도가 되면 서서히 원래의 7×7 패턴으로 되돌아가기 시작한다. Si(111) 7×7기판의 온도를 200℃∼600℃로 유지하면서 K을 일정시간(450℃에서 3×1이 형성되는 증착시간)이상 증착시킨 경우에 250℃까지는 상온의 경우와 비슷한 형태의 변형된 7×7 패턴이 관측되고, 300℃∼550℃일때는 3×1, 550℃ 이상에서는 1×1 구조가 관측되었다. 이때 300℃∼550℃에서 형성된 Si(111) 3×1-K 구조는 450℃에서 1분 정도 annealing 하면 항상 Si(111) 1×1-K 구조로 상전이가 일어남을 관측하였다. Potassium adsorbed surface structures of Si(111) 7×7 surface at room and high temperatures(200℃∼600℃) were investigated by RHEED. Potassium adsorption on the Si(111) 7×7 surface to saturated coverage at room temperature changed the RHEED pattern of Si(111) 7×7 to Si(111) 7×7-K. Subsequent heating of the Si(111) 7×7-K surface above 350℃ results in a Si(111) 7×7 with desorbing K. The RHEED pattern of the K-adsorbed on the Si(111) 7×7 surface up to the adsorption temperature of 250℃ was the modified 7×7 pattern, quite similar to that of the Si(111) 7×7-K, observed at room temperature. The 3×1 structure was observed in the temperature of adsorption between 300℃ and 550℃. Regardless of the adsorption temperature, a phase transition always took place from the Si(111) 3×1-K structure to Si(111) 1×1-K after annealing at 450℃ over 1 minute.

Cardiac tumors, especially the primary tumors involving any part of the heart are extremely rare and its relative incidence has been reported to be approximately 0.02%. We report a patient with huge cardiac hemangioma who complained of shortness of breath, general weakness, and dizziness, Imaging study by echocardiography and computed tomography of thorax revealed a huge lobulating mass like a bunch of grapes in the right chamber of heart. The surgical exploration of thorax was performed and a histological diagnosis of spindle cell hemangioma was obtained by microscopy. The patient was treated by surgical resection of the tumor and doing well after surgery. Our experience indicated that prompt diagnosis and treatment of cardiac hemangioma is imperative for patients' prognosis.
Gullian Barre Syndrome 患者 1例에 대한 症例報告
임승민,안정조,최영,조현경,김민상,유병찬,오병렬,김윤식,설인찬 대전대학교 한방병원 2002 惠和醫學 Vol.11 No.1
Gullian Barre Syndrome is an acute symmetric polyradiculoneuropathy that typically presents as a progressive flaccid paralysis. The pathology is believed to be caused by both cellular and humoral immune processes The possibility of death is 3-5% and About 20% of patients require mechanical ventilaton. Recently We have experienced a patient who had suspected Gullian Barre Syndrome for 60days, his condition weakness and pain was impoved through the herb and acupucture Therefore I reported it for the treatment.

<P>An effective way to improve the functionalities and stabilities of metal organic frameworks (MOFs) is developed by employing exfoliated metal oxide 2D nanosheets as matrix for immobilization. Crystal growth of zeolitic imidazolate framework 8 (ZIF-8) nanocrystals on the surface of layered titanate nanosheets yields intimately coupled nanohybrids of ZIF-8-layered titanate. The resulting nanohybrids show much greater surface areas and larger pore volumes than do the pristine ZIF-8, leading to the remarkable improvement of the CO2 adsorption ability of MOF upon hybridization. Of prime importance is that the thermal- and hydrostabilities of ZIF-8 are significantly enhanced by a strong chemical interaction with the robust titanate nanosheet. A strong interfacial interaction between ZIF-8 and the layered titanate is verified by molecular mechanics simulations and spectroscopic analysis. The universal applicability of the present strategy for the coupling of MOFs and metal oxide nanosheets is substantiated by the stabilization of Ti-MOF-NH2 via the immobilization on exfoliated V2O5 nanosheets. The present study underscores that hybridization with metal oxide 2D nanosheets provides an efficient and universal synthetic route to novel MOF-based hybrid materials with enhanced gas adsorptivity and stability.</P>
