Amorphous (Fe Ni) Si B (x=0, 0.2, 0.4, 0.6, 0.8, 1, y=6, 8, 10, 12) alloys were prepared by a single roll quenching method. Both composition and temperature dependence of saturation magnetization were studied by vibrating sample magnetometer(VSM). Electrical resistivity was measured by four probe method and the power loss was calculated which is related change of frequency by A.C B-H loop tracer. Domain patterns were observed by Bitter method. 1. The preparation of amorphous alloys with all composition was possible, and after heat treatment crystallization occurred, resulting in Fe₃B and Ni₃B. 2. The saturation magnetization was increased with B content and the Curie temperature was about 750°K. 3. Electrical resistivity in amorphous alloys was twice in crystalline alloys and the crystallization temperature was increased with Si content. 4. The power loss of amorphous (Fe Ni) Si B alloys which is dependent on frequency was decreased with decreasing Si content and Ni content. 5. By heat treatment, the fingerprint type domain was gradually diminished and the decrease in power loss was also observed.

최근 중국 자본의 북한 진출이 비약적으로 확대되면서 양국의 경협 발전이 자연스럽게 중국의 대북 영향력 확대로 이어져, 지나친 중국 의존도 심화가 경제적 예속으로 이어지지 않을까 하는 우려가 대두되고 있다. 그러나 중국의 최근 북한과의 경제협력의 본질은 북한의 경제예속화보다는 경제적 붕괴를 막기 위한 것이다. 전략 면에서는 미군과의 직접 대치를 막아주는 군사적 완충지대를 유지하여 자국의 경제발전에 전념하려는 것이다. 나아가 북한 지도부를 설득하여 개혁 개방을 적극적으로 추진하도록 함으로써 자국과 국경을 맞대고 있는 한반도 북부의 불안정 요인을 근원적으로 해결하려는 것이다. 이렇게 볼 때 중국의 한반도 전략은 북핵문제 등과 관련하여 어느 정도 중국과 북한 양국에 윈-윈의 성과를 거두고 있다고 할 수 있다.민족통일의 논의와 접근방식 중에서 경제 분야는 일방적인 지원이 아닌 남과 북의 산업간, 경제요소 간 상호협력이 가능하고 쌍방에 도움이 되어야 가장 실효성이 크고 부작용이 적다고 할 수 있다. 산업협력에서 폐쇄된 민족주의의 시각은 또 다른 남남갈등의 요인이 될 수 있다. 다시 말하여 민족경제의 차원에서 중국에 대한 편중해소와 중국자본과 우리의 형평성 논리가 남북경협의 전제 조건이 되거나 나아가 남북경협을 가로막는

In order to investigate the magnetization mechanism of a amorphous metallic materials and to develop a new soft magnetic materials, the magnetic and electrical properties of amorphous (Fe Cox) Si B alloys have been studied systematically The specimen was prepared by single-roll method. The saturation magnetization was measured by a vibrating sample magnetometer from 300°K to 810°K in vacuum of 2×10torr. The saturation magnetostriction constant was measured by small-angle magnetization rotation method. The coercive force and AC power loss were measured by a AC B-H loop tracer. The electrical resistivity was measured by four-probe technique form 300°K to 1200°K in vacuum of 2×10 torr. The magnetic domain was observed by Bitter technique. The results are as follows. 1) The possible range of amorphous forming composition is 0.2 X 0.9 for the (Fe Co) Si B alloys. 2) According to the results of investigation the composition-dependence of the saturation magnetization, coercive force, magnetic domain, electrical resistivity and crystallization temperature, amorphous (Fe Co) Si B alloys showed best soft magnetic characteristics between x=0.7 and x=0.9

Overexpression of Recombinant Arysulfatase Cloned from Pseudoalteromonas carrageenovora
김종오,남수완,김형락,김석렬,임재명 한국수산과학회 2005 Fisheries and Aquatic Sciences Vol.8 No.3
Arylsulfatase cloned from a marine bacterium, Pseudoalteromonas carrageenovora, was over-expressed in Escherichia coli. Most of the recombinant arylsulfatase was found in the cell lysate with induction up to 10μM IPTG. However, enzyme activity was observed both in the culture supernatant and cell lysate by induction with IPTG concentration of 50-5,000μM. Most of the recombinant enzyme was localized in the periplasmic space with 10μM IPTG induction, while half of the enzyme was distributed in the periplasmic space with 50μM IPTG induction. Cell growth and arylsulfatase activity did not change with the induction time, and the level of recombinant arylsulfatase expression was maintained at 4-5 U/mL after 6 to 14 hr of culture.

일부 어린이집의 실내공기 중 메치실린내성 포도알균의 오염 실태 및 특성

Objectives: This study aims to understand the concentration, diversity, and antibiotic characteristics of staphylococci present in the indoor air of child-care facilities. Methods: Air sampling was performed from October 2012 to January 2013 in 120 child-care facilities in Seoul, Korea. Methicillin-resistant bacteria were selected from the total obtained airborne bacteria and subjected to 16S rRNA analysis for methicillin-resistant staphylococcal species determination. Identified staphylococcal strains were tested for resistance to a range of antibiotics. Results: Average total airborne bacterial concentration was $508.9{\pm}246.3CFU/m^3$. Indoor concentration of total airborne bacteria had a significant positive correlation with the $CO_2$ concentration in the child-care facilities. Methicillin-resistant staphylococci were present in 13.3% of the child-care facilities studied. A total of four species (S. epidermidis, S. cohnii, S. saprophyticus, S. sp.) and 55 strains were identified from the indoor air of the child-care facilities. Staphylococcus cohnii was the most common species (54.5%), followed by S. epidermidis (38.2%). All of the isolated staphylococcal strains exhibited high resistance to oxacillin, erythromycin, mupirocin, and ceftizoxime. Especially, S. saprophyticus strains showed more multidrug resistance to oxacillin, vancomycin, clindamycin, erythromycin, lincomycin, ceftizoxime, mupirocin, and tetracycline than did other species. Conclusion: The results of this study showed that a monitoring system for multidrug-resistant bacteria is needed in facilities for children, as the community-associated infections of these bacteria are increasing.
