In pursuit of a potential low-resistive contact structure, ErSi2-x was grown on an excessively P-doped and highly strained epitaxial Si layer (Si:P with a P concentration of ∼2.8 at%), and its microstructure was investigated in comparison to that grown on a conventional Si(001) substrate. On the Si substrate, ErSi2-x grains nucleated with a local epitaxial relationship and grew to form a polycrystalline film with a preferred alignment of ErSi2-x(10 1 ¯ 0)//Si(001) in a largely strained state. However, the epitaxial relationship at the interface during the ErSi2-x nucleation stage was disrupted, and randomly oriented columnar ErSi2-x grains grew on the Si:P(001) layer. Several experiments to separate the possible strain and doping effects showed that inhibition of the epitaxial nucleation of ErSi2-x grains was induced by excessive P accumulation at the interface region rather than by the strain effect. P enrichment at the interface encouraged ErSi2-x film growth without a preferred orientation, and the intermittent P-deficient areas worsened the interface roughness by provoking the local intrusion of ErSi2-x grains toward the Si:P layer.

본 연구에서는 전통적 명태식해를 제조한 다음 저장.숙성조건에 따른 명태식해의 항균성, 항산화성, 항고혈압성 및 항콜레스테롤성 등의 생리적 기능특성에 대해 조사하였다. 항균성에서는 9종의 균주에 대해 모두 항균작용이 있는 것으로 나타났으며 , 이중 gram 양성균에 대해 Listeria monocytogenes를 제외하고 저장 직후에 항균활성이 나타났으며, 모든 gram 양성균에 대해 전 저장기간 동안 항균활성이 확인되었고, Staphylococcus aureus에 대해 강한 항균활성을 나타내었다. 반면에 gram 음성균 및 진균류에 대해서는 항균활성 이 gram 양성균에 비해 약하였다. 항산화성은 저장.숙성조건에 따라 모두 관능적으로 맛이 우수한 15~16일 경에 가장 강한 항산화활성을 나타내었으며, 그 후로는 저장기간이 증가함에 따라 감소하는 경향을 나타내었다. 항고혈압성은 명태식해 제조직후를 제외하고는 모든 저장.숙성조건에서 항고혈압활성이 나타났으며, 항콜레스테롤성은 2 $0^{\circ}C$ 15일과 변온 16일에서만 항콜레스테롤활성이 검출되었다. 이러한 결과를 바탕으로 할 때 전통적인 방법에 따라 제조된 명태식해는 김치류와 같은 우수한 생리적 기능성을 가지고 있었으며, 명태식해의 유통기간 연장을 위한 변온조건에서도 그 생리적 기능성이 계속해서 유지됨을 알 수 있었다. 【The physiological functionalities such as antimicrobial activity, antioxidative activity, angiotensin-I converting enzyme (ACE) inhibitory activity and bile acid binding capacity were measured for the solvent-fractionated methanol extracts of Alaska pollack sik-hae at various time intervals during fermentation. Two temperature schemes of fermentation were studied: constant temperature of 2 $0^{\circ}C$ (A) and stepwise change from 2 $0^{\circ}C$ (10 days) to 5 $^{\circ}C$ (B). The methanol extracts of Alaska pollack sik-hae showed antimicrobial activities against 9 kinds of micro-organisms including pathogenic and food poisoning strains. Among these, gram positive bacteria, in particular Staphylococcus aureus, showed more sensitivity to the extracts than gram negative bacteria and fungi. Antioxidative activity (EDA $_{50}$ ) increased until 15 days (A, 0.92 mg/ $m\ell$ ) or 16 days of fermentation (B, 0.94 mg/ $m\ell$ ), and then gradually decreased. ACE inhibitory activity was observed in all fermentation time except 0 day, and bile acid binding capacity at 15 days (A) and 16 days (B) only.】

We present a fast parallelized under-relaxation iterative algorithm applicable in solving a large scale Laplace equation that is incorporated into injection molding analysis. The rate of speed gain versus number of processors is studied using three models with different data sizes. Experimental results of running on 32 Intel Paragon processors show reductions up to 98% of original computation time obtained by using a SGI Challenge. Moreover, due to a better memory utilization, the observed speed gain is greater than the proportional increase in the number of processors used.
