과거 충돌회피를 위한 알고리즘은 충돌위험을 결정하는데 항해사 대신 위험도를 판단하여 충돌회피를 하려고 한다. 그러나 경우에 따라서 국제해상충돌예방규칙에 맞지 않게 충돌 회피를 시행한다. 또한 타선과의 피항 관계를 항해사가 주시하고 기억해야 하는 것은 항해사에게 부담을 줄 수 있다. 따라서 국제해상충돌예방규칙에 맞게 피항 관계를 정의하여 항해사에게 알려줌으로써 피항 행동을 결정하는데 시간 및 인적 실수를 줄여줄 것으로 기대한다.

DA-1131은 Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, Proteus mirabilis, Proteus vulgaris 및 Pseudomonas aeruginosa 의 시험균주에 대하여 1-4의 MBC/MIC 비를 나타내었으며, 약물첨가에 의한 세균증식억제 과도 매우 우수하였으므로 광범위의 강력한 살균력을 나타내는 것으로 확인되었다. DA-1131의 PAE는 S. aureus Smith에 대하여는 1.28시간, K. pneumoniae 1에 대하여는 0.65시간, P. aeruginosa 93에 대하여는 1.90시간으로 나타나, MIC 이하의 낮은 농도에서도 세균에 대한 생육저해 효과가 관찰되었으며, 이러한 현상은 E. coli K-12에 DA-1131을 1/4 MIC(0.0125 $\mu\textrm{g}$/$m\ell$) 농도로 작용시켰을 때 균의 팽화와 신장 및 구형화가 동시에 일어나는 등 균형태변화를 초래하는 효과와 큰 상관성을 나타내었다. 또한, DA-1131은 감염방어효 에 매우 큰 영향을 끼치는 mouse macrophage와 매우 우수한 협력적살균작용을 나타내어 E. coli K-12 생세포는 1/16 MIC 이상의 DA-1131 공존하에서 쉽게 식균소화(phagocytosis) 되었다.

The acute toxicity study of combined antibiotic (Cefatrizine / Clavulanic Acid), a formulation consisting of cafatrizine and clavulanic acid in a ratio of 2 : 1, was evaluated in rats. The antibiotic was orally administered with single dose in dose levels up to 5 g/kg (0, 1.25, 2.5, 5 g/kg). Treatment-related effects were limited to soft stool excretion and caecal dilatation, but histologically no morphological changes could be detected in caecum. In hematology, serum-chemistry parameters and histopathology, no drug-related changes were found. The results of the present study indicate that cefatrizine / clavulanic acid has a low toxic potential and the oral $LD_{50}$values exceed 5 g / kg in rats

Data repliciation techniques of distributed database a allocation methods occures to overhead to change together all repkicas for consistency maintenance at updates .In case of data migration horizontal or vertical fragment migration has caused to caused to increase data communication.In this paper we purpose batch proxessing method groups the associated items of table and stores temporary table assciated with file relication and migrations.This method increase the usagility of system buffer in distributed trancsaction processing with a number of data inputs and updates.After all,it improved the perform-ance of distributed transaction system by reducing disk I\O processing time and the cost of data cimmunication among local sites.

3-Methylcrotonyl-CoA carboxylase (MCC) is a biotin-dependent enzyme involved in leucine metabolism. We describe a patient with MCC deficiency who manifested with Reye syndrome-like illness with status epilepticus, metabolic acidosis, hypoglycemia, hyperammonemia, elevated liver enzymes and neurologic impairments after the viral gastroenteritis and then, has suffered from Lennox-Gastaut syndrome. Urinary organic acid analysis revealed increased excretion of 3-hydroxyisovaleric acid and 3-methylcrotonylglycine. This patient was managed with leucine restriction diet and supplementation of biotin and carnitine but was not so effective. He has suffered from neurologic sequelae such as Lennox-Gastaut syndrome, motor and cognitive impairement.
