  • 우주물체 전자광학 감시체계는 빠르게 이동하는 우주물체를 지구상에서 신속하고 정확하게 관측할 수 있는 장비이다. 이 체계의 주요 부분인 광학 망원경은 직경 0.5 m의 비구면 주 반사경과 직경이 0.2 m인 비구면 부 반사경 그리고 5매의 보정 렌즈로 구성된 카세그레인 타입의 망원경으로 2도의 광시야를 갖도록 상 분석 및 미광 분석을 통하여 광학적 성능을 최적화하였다. 망원경의 광기계 구조는 설치 환경요소 및 관측 환경 요인으로 인한 광학적 변형을 최소화하도록 설계하였다. 본 논문에서는 우주물체 전자광학 감시체계의 요구조건을 만족하는 광시야 망원경의 광학계 및 광기계 구조 설계를 논의하고자 한다.

  • The purpose of this study was to verify the validity of the Patient Severity Classification Tool by examining the correlations between the APACHE Ⅲ and the Patient Severity Classification Tool and to propose admission criteria to the ICU. The instruments used for this study were the APACHE Ⅲ developed by Knaus and the Patient Severity Classification Tool developed by Korean Clinical Nurses Association. Data was collected from the 156 Medical ICU patients during their first 24 hours of admission at the Seoul National University Hospital by three trained Medical ICU nurses from April 20 to August 31 1999. Data were analyzed using the frequency, $x^2$, Wilcoxon rank sum test, and Spearman rho. There was statistically significant correlations between the scores of the APACHE III and the Patient Severity Classification Tool. Mortality rate was increased as patients classification of severity in both the APACHE III and the Patient Severity Classification Tool scored higher. The Patient Severity Classification Tool was proved to be a valid and reliable tool, and a useful tool as one of the severity predicting factors, ICU admission criteria, information sharing between ICUs, quality evaluations of ICUs, and ICU nurse staffing.

  • VLCC에 의한 SK에너지 울산CLX와 인천CLX의 일원화된 효율적 원유 수급체계에 따른 물류비용의 절감, 이에 따른 국가 산업 경쟁력확보 및 항만경쟁력 강화를 위한 고도화 사업의 일환으로 고부가가치 선박인 VLCC가 인천항에 처녀입항하게 되었다. 이로 인한 해상교통관제센터(VTS)의 안전대책이 요구되어 비교적 통항량이 많고 항로길이가 긴 인천항의 VLCC운항 계획에 따른 해상교통 혼잡도 등, 다각적인 통항 안전성 및 VLCC 입출항에 따른 타 통항선과의 항행안전 관계등을 점검하여, 계속적인 VLCC 입항에 따른 항행 위험성을 파악하고, 앞으로의 인천항만 안전을 위한 통항안전관리대책을 모색하고자 한다.

  • The gene for ${\beta}-agarase$ of an Agarivorans sp. JA-1 was expressed in Bacillus subtilis DB104, 168 and ISW1214 strains for mass-production. Among 3 host strains, B. subtilis ISW1214 secreted the highest amount of recombinant ${\beta}-agarase$ with a specific activity of 201 U/mg and 360 mg of protein into culture broth. This was approximately 130-fold higher than the production in E. coli as an expression host. Recombinant enzyme produced neoagarooligosaccharides such as neoagarohexaose, neoagarotetraose, and neoagarobiose from agar. Produced neoagarooligosaccharides showed antibacterial activities against gram-negative E. coli and gram-positive B. subtilis at a concentration of 1.5%. These data suggest that neoagarooligosaccharides could be an useful preservative for food industry.

  • Authors report the glycoside hydrolase (GH) family 16 ${\beta}$-agarase from the strain of Agarivorans sp. JA-1, which authors previously stated as recombinant expression and characterization of GH-50 and GH-118 ${\beta}$-agarase. It comprised an open reading frame of 1,362 base pairs, which encodes a protein of 49,830 daltons consisting of 453 amino acid residues. Valuation of the total sequence showed that the enzyme has 98% nucleotide and 99% amino acid sequence similarities to those of GH-16 ${\beta}$-agarase from Pseudoalteromonas sp. CY24. The gene corresponding to a mature protein of 429 amino acids was recombinantly expressed in Escherichia coli, and the enzyme was purified to homogeneity by affinity chromatography. It showed maximal activity at $40^{\circ}C$ and pH 5.0, representing 67.6 units/mg. Thin layer chromatography revealed that mainly neoagarohexaose and neoagarotetraose were produced from agarose. The enzyme would be valuable for the industrial production of functional neoagarooligosaccharides.

  • 에폭시 수지 DGEBA/MDA/GN계의 트링 열화에 미치는 전압과 온도의 영향에 대한 고찰을 통하여 고분자 절연재료의 절연파괴 거동을 연구하였다. 전압 인가시간에 따라 트리의 성장속도은 역S자의 형태로 나타났다. 인가전압과 온도가 증가함에 따라 트리의 성장속도는 증가하였으며 트리형상의 복잡함, 즉 국부적인 트링열화의 정도는 인가전압이 감소하거나 온도가 증가한 경우에 높게 나타났다. 절연파괴 강도는 유리 전이온도 이상에서 급격히 감소하였다.

  • A survey study was carried out on the preparation methods of the Winter Kimchies in Seoul. Chung Cheong and Kang Won area by questioning 203 homes Individually. The results showed that the cabbage Kimchi was prepared more than 95o of total Kimchi a good heads of the Chinese cabbage were selected as proper quality of the cabbage. The cabbage were brined for 7∼10 hours with using sun-dried salts mostly(66∼78%) In Seoul and Chung Cheong area the quality of Chinese cabbage was regarded as the primary factor and the seasoning materials in Kang Won area for good quality of Kimchi, more than 70eA of the residents prepared Kimchi in Kimchi jar, and the correlation between the jar use kind of resident such as house or apartment was significantly high (p< 0.000)
