This study was carried out to have basic and applied informations to find the optimum nitrogen fertilization level for organic cultivation and to investigate early growth characteristics of Schizandra chinensis Baillon. Different application levels of the organic fertilizer were based on the recommended rate of N fertilizer. Five different levels of the organic fertilizer were applied to S. chinensis and early growth responses such as the length of vine, the diameter of vine, the number of leaves, and the number of branches were investigated. Lengths of main and total vines were shown longer at the level of 1.0 time organic fertilizer than those at others. The vine length at early growth was the highest at the level of 1.0 time organic fertilizer among the treatments. Stem diameter was shown thicker level of 1.0 time organic fertilizer than others on August and September, whereas on October it was the thickest in the conventional cultivation. Number of leaf was increased higher at the level of 1.0 and 2.0 times organic fertilizer than that in the compared to conventional. The number of branches was appeared the lowest at the level of 1.0 time organic fertilizer at early growth, however they were increased through progressing their growth stages. They were not significantly difference among the treatments except for the level of 2.0 times organic fertilizer. Based on the research results, the growth of S. chinensis was commonly higher at the level of 1.0 time organic fertilizer compared to other treatments.

Inhibitory Effect of Cordycepin on Human Platelet Aggregation

박화진,--,--,--,--,--,-- THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2004 Journal of biomedical laboratory sciences Vol.10 No.1

Cordycepin separated from Cordyceps militaris is a major physiologic active component in Cordyceps militaris. The platelet aggregation is stimulated by Ca^(2+), which is either mobilized from intracellular endoplasmic reticulum or transported from extracellular space. cGMP antagonizes the actions of Ca^(2+). Based on these facts, we have investigated the effects of cordycepin on the mobilization of Ca^(2+) and the production of cGMP on collagen (10 ㎍/ml)-induced human platelet aggregation. Cordycepin potently stimulated the human platelet aggregation induced by collagen (10 ㎍/ml) in a dose-dependent manner. Cordycepin (500 μM) inhibited also the collagen-induced human platelet aggregation in the presence both 1 mM and 2 mM of CaCl_(2). These are in accord with the results that cordycepin inhibited the Ca^(2+)-influx on collagen-induced human platelet aggregation. These results suggest that cordycepin decrease the intracellular Ca^(2+) concentration to inhibit collagen-induced human platelet aggregation. Besides, cordycepin increased the level of cGMP on collagen-induced human platelet aggregation. This result is related with the decrease of intracellular Ca^(2+) concentration, because cGMP inhibits the mobilization of Ca^(2+). In addition, cordycepin inhibited the human platelet aggregation induced by LY-83583, inhibitor of guanylate cyclase. This result suggested that cordycepin inhibit the platelet aggregation by stimulating the activity of guanylate cyclase. In conclusion, we demonstrated that cordycepin might have the antiplatelet function by inhibiting Ca^(2+)-mobilization via the stimulation of the production of cGMP.

The waste foundry sand might be recycled in concrete, resulting in energy saving and enviromental protection. An half Factorial Experiments were performed with the variables of W/C ratio, S/A, Sand/Waste foundry sand ratio and Slump as a preliminary study for optimum mis design of concrete. The resutls show that then W/C ratio is the most important factor to the concrete strength. The substitute fo waste foundry sand uo to 305 has little influence, saying that it can substitute the fine aggregate without damaging the concrete properties.

The maturity concept was adopted to predict the strength of concrete, which was subjected to several temperature levels and variable curing conditions. Penetration test and compressive test were conducted to measure the initial and final setting time and the compressible strength of concrete specimen, respectively. Also, the temperature and time were measured at some time intervals for calculating the maturity. The initial and final setting were delayed as the w/c ration increased and curing temperature decreased. The relationships at the relative strength and the equivalent age were proposed at different w/c ratio for the several temperature curing conditions, and these were applied for the variable curing conditions.

석회화 섬유종양은 원인 미상의 흔하지 않은 양성 중앙이다. 이 종양은 복강이나 복막에서 기원하는 경우가 많으나 위에서 기원한 석회화 섬유종양은 매우 드물 다. 건강검진시 위내시경에서 우연히 발견된 위 점막하 종양 평가를 위해 28세 여성이 본원으로 전원되었다. 본원에서 시행한 위 내시경에서 위 중간체부에 1.2cm의 평탄한 표면의 위 점막하 종양이 관찰되었다. 초음파 내시경을 시행하였고 점막하층에 위치한 불균질한 저에코성의 병변과 함께 종양 내부에는 음향 음영을 동반한 다수의 고 에코성의 부위가 관찰되었다. 위 점막하 중앙은 악성종양을 완전히 배제할 수 없기 때문에 내시경적 점막하 절제술을 시행하였다. 조직 검사결과 종양은 석회화률 동반하는 호산구성 콜라겐 섬유가 풍부한 위 석회화 섬유 종양으로 진단되었다. 이에 위 점막하 중앙에 관한 다른 문헌을 고찰하면서 본 증례를 보고하는 바이다.

산업폐기물인 폐주물사를 재활용하여 에너지 절감과 환경오염효과를 얻을 수 있다. 반요인실험법을 사용하여 폐주물사를 잔골재에 일정비율 치환한 콘크리트의 최적배합설계 제시를 위한 예비실험에서 물-시멘트비, 폐주물사의 잔골재 치환율, 잔골재율, 슬럼프와 같은 주요변수와 변수사이의 2차상호작용을 파악하였다. 예비실험결과 폐주물사의 잔골재치환율을 70%까지 실시하였을 때 폐주물사를 혼입한 콘크리트의 강도발현에 가장 중요한 변수는 물-시멘트비로 분석되었고 폐주물사의 잔골재치환율은 거의 영향이 없는 것으로 분석되어 폐주물사를 콘크리트의 잔골재로 대체할 수 있음을 알 수 있었다. 각 변수의 2차상호작용에서는 폐주물사의 잔골재 치환율과 잔골재율의 상관관계가 콘크리트의 강도발현에 가장 큰 영향을 미치는 것으로 나타났다. 목표압축강도에 대한 최적배합조건을 폐주물사의 잔골재 치환율에 따라 물-시멘트비, 잔골재율에 대해 제시하였다. The waste foundry sand might be recycled in concrete, saving energy and protect-ing environment. An half- factorial experiments were performed with the primarary variable such as water- cement raito, waste foundry sand substitution ratio, fine agg-regate ratio and slump as a preliminary study for optimum mix design of concrete. The preliminary study show that the water- cement ratio is the most important factor to the concrete strength, followed by slump. The substitute of waste foundry sand up to 70% has little infulence, indicating that it can substitute the fine aggregate without damaging the Concrete strength. The interaction between waste foundry sand substitution ratio and fine aggregate ratio was most significant to the concrete strength among the 2-way interaction variable. Only compressive strength affect to the formation of optimum mix design area as target compressive strengh becomes bigger. Optimum mix designs of concrete incorporating waste foundry sand, satisfying the target responses, were proposed in terms of waste foundry sand substitution ratio, water cement ratio and fine aggregate ratio.

In the time when we fabricated the NPH bipolar transistor the temperature annealing was needed. Then the properties of transistor was damaged because of inducing the silicon lattice defects. In this paper, proposed codiffusion method was able to control of junction depth by implant energy, dose concentration, diffusing temperature and annealing time control. In addition to, we studied for developed the transistor of high speed switching.
