국예비 해기사 교육의 일환으로 심화교육의 일환으로 IMO 활동, 국제적인 주요협약 및 규정의 종류, 체계 및 전반적인 내용이해를 교육하기 위한 산학간 해기사 교육프로그램을 제안한다. 전체적 교육의 구성, 교육결과에 대한 만족도 분석을 통하여 바람직한 교육프로그램을 제시한다. 교육의 결과로서 미래 해기사의 IMO 활동에 대한 관심을 드높이고, 참신한 아이디어 발굴을 통한 국가 의제개발의 씨앗을 창출해내 는 역할이 기대되고, 해기사의 자긍심을 고양시키는 부수적인 잇점도 가질 수 있을 것이다.

Copper is able to work as a current collector under wide range of hydrocarbon fuels without coking in Solid oxide fuel cells (SOFCs). The application of copper in SOFC is limited due to its low melting point, which result in coarsening the copper particle. This work focuses on the sintering of copper powder with ceria coating layer. Ceria-coated powder was prepared by thermal decomposition of urea in solution, which containing CuO core particles. The ceria-coated powder was characterized by XRD, ICP, and SEM. The thermal stability of the ceria-coated copper in fuel atmosphere was observed by SEM. It was found that the ceria coating layer could effectively hinder the grain growth of the copper particles

Sulfonamides, a therapeutically important group of antimicrobial drugs, are widely used to treat and prevent the acute systemic and skin infections in dairy cattle. They also pose an economic hazard through inhibition of growth of dairy starter cultures. This study was carried out to compare four screening methods for detection of sulfamethazine in milk and determine the positive milk sample by HPLC method. Sulfamethazine was used to spike at five levels of sulfamethazine. The Lac-Tek test and CharmII test were also consistent better than TTCII test and Delvo SP test in sulfamethazine detection. Analysis probabilities of obtaining a positive response with TTCII test and Delvo SP test assay at 50 ppb sulfamethazine level in milk samples were only 14%, 42% each. Whereas using the Lac-Tek test and CharmII test would have resulted in 100% identification of the five levels. Determination of sufamethazine using the HPLC method in the spiked milk were 10.64, 19.30, 30.76, 38.83 and 50.23 ppb, respectively.
