This study was carried out to obtain informations on the variations of oil content and fatty acid composition among 90 Korean perilla collections. Average oil content of 90 perilla collections was 44.2% with a range from 29.7% to 61.9%. Perilla collections with late-maturing, super-large seed and gray seed coat showed higher oil content than other types in general. Average saturated fatty acid content in perilla oil was 9.0% with a range from 8.2% to 10.7%, while average unsaturated fatty acid content varied from 89.3% to 91.8% with a mean of 91.0%. Contents of saturated and unsaturated fatty acids were not related to maturity. There were no differences in the contents of saturated and unsaturated fatty acids according to maturity. Linoleic acid and linolenic acid contents were the highest in the super large-sized group(15.5%) and in the large-sized seed group(61.4%), respectively, while contents of fatty acids among the perilla collections were variable with different seed coat colors. Most of the traits studied were not significantly correlated with oil content, but linoleic acid($\omega$ 수식 이미지-6) content was negatively correlated (r=-0.217*) with linolenic acid(ω-3) content.

홍석우,임종철,고호성 부산대학교 1999 生産技術硏究所論文集 Vol.56 No.-

Anchor is used for a restraining of a ground deformation in the retaining wall, slope-stability et ect. When pullout load is applied to the anchor in the ground, the behavior of the anchor in the ground is differed by the rigidity of anchor body and ground. In this study, the stress-behavior is analyzed by the numerical a analysis on the surface of an anchor body according to the pullout of an anchor. Mostly, The analysis is focused on the change of a shear stress according to the coefficient ratio of elasticity. The coefficient ratio of elasticity(E_(a)/E_(r)) is defined by the ratio between elastic modulus of ground(E_(r)) and that of anchor body (E_(a)). By using this ratio, the progressive failure of anchor body can be analysed. 앵커는 흙막이 벽, 사면안정 등에서 사용되는 지반변형 억제공법이다. 앵커가 지중에서 인발하중을 받으면 앵커체의 강성과 지반의 강성에 따라 각각 다른거동을 하게 된다. 본 논문에서는 인장형 및 압축형 앵커의 인발에 따른 표면에서의 응력거동을, 주로 탄성계수비에 따른 전단응력의 변화에 중점을 두고 수치해석 기법을 이용하여 분석하였다. 여기서, 탄성계수비(coefficient ratio of elasticity)란 지반탄성계수(E_(r))와 앵커체탄성계수(E_(a))의 비 (E_(a)/E_(r))를 말하는데, 이 탄성계수비에 의해 앵커의 진행성 파괴에 대한 영향을 평가할 수 있다.

Abstract This study was performed to assess the amount of altered serotonergic responsivity in individuals with repeated aggressive behaviors; compared with normal controls. Sixteen aggressive (delinquent criminals with repeated aggressive behaviors) and seventeen controls(medical college students) were selected and assessed their severity of aggression by several psychological instruments. The platelet 3H-imipramine binding sites which is known to correlate the serotonergic function of the central nervous system were measured. The results are as follows. 1) Mean scores of physical aggression in the aggressive subjects were found to be significantly higher than normal controls(p<.01). And impulsivity, hostility, psychoticism in the aggressives were found higher than controls, also. 2) In the platelet 3H-imipramine binding, the aggressives had a tendency of reduced maximal binding sites(Bmax) comparing with controls(p=.0841). 3) There was no statistically significant differences between two groups in the binding coefficients (Kd) of platelet 3H-Imipramine binding. 4) The value of maximal binding sites(Bmax) showed significant inverse correlations with aggressive scale scores of PFAV(r=-.6311), and physical aggression scale scores of CTS(r= -5377).

그리운드 앵커의 시공이 나날이 증가되고 있는 현실에서, 연약한 지반에도 시공 가능한 지반개량앵커(SI 앵커)의 정확한 극한인발력의 산정과 인발저항기구를 연구하는 일은 매우 중요한 일이다. SI 앵커는 지반개량앵커를 의미한다. 앵커를 지지하는 지반을 J.S.P 로 개량한 짓이다. SI 앵커는 인발저항기구를 알기 위해 SI 앵커체의 표면과 앵커체 두부의 응력을 측정하는 것이 필요하다. 본 연구에서는 현장실험과 실내모형실험을 통해 SI 앵커체 표면에서의 응력을 측정했고, 산정식에 의한 계산 결과치와 비교했다. 본 연구의 결론은 다음과 같다. (1) SI 앵커의 거동은 일반 마찰방식 앵커의 거동과는 다르게 나타나는데, 이는 SI 앵커의 저항력은 지압저항력과 마찰 저항력의 합에 의해 결정되기 때문이다. (2) SI 앵커의 설계 시는 진행성 파괴의 영향을 고려하여야 한다. (3) SI 앵커의 지압저항에 의해 앵커두부의 변위는 감소되고, 앵커의 극한인발력은 일반마찰방식앵커에 비해 증가한다. (4) SI 앵커는 일반앵커가 시공되기 어려운 연약지반 내에 정착할 때 특히 효과적이다. Day after day, use of ground anchor is increasing in execution, It is significant to calculate the ultimate pullout force exactly and to research the mechanism of pullout resistance of SI anchor. SI anchor means the Soil Improvement anchor. Ground for anchoring is improved by J. S. P. In order to analyze the mechanism of pullout resistance of SI anchor, it is necessary to measure stresses on the SI anchor surface and SI anchor head. In this study, we measured stresses on the SI anchor surface by field tests and laboratory model tests and compared with calculated results. The conclusions of this study are as follows: (1) The behavior of SI anchor is different from that of friction anchor, because pullout resistance of SI anchor is made by bearing and frictional force. (2) In the design of SI anchor, progressive failure should be considered. (3) By the bearing resistance of SI anchor. the displacement of anchor head is decreased and the ultimate pullout force of anchor is increased comparing with general friction anchor. (4) SI anchor can be used in soft ground effectively.
