CV 黑鉛鑄鐵의 組織 및 性質에 미치는 Cu添加의 影響
金明鎬,朴興日 울산대학교 1985 연구논문집 Vol.16 No.2
Mg-REM系 合金을 CV 黑鉛化劑로 添加한 CV 黑鉛鑄鐵의 組織과 그 性質에 미치는 合金元素로서의 Cu添加影響을 調査하였다. Cu의 添加量이 2.0%까지 增加함에 따라 다음과 같은 結果를 얻엇다 : 첫째, Cu添加臺이 增加할수록 熔湯中의 5含量이 減少하였으며 殘留 Mg의 回收率은 增加 하였고, 黑鉛組織은 CV 黑鉛狀에서 球狀黑鉛狀으로 천이하는 傾向을 나타내었다. 둘째, Cu添加量이 1.2% 以上되면 基地組織은 완전히 pearlite化하며, 多量의 free carbide가 析出함을 알 수 있었다. 세째, Cu添加量이 增加함에 따라 常溫 및 高溫引張性質은 向上되었다. The effects of copper. as an alloying element on the structure and properties of Compacted- Vermicular graphite cast iron which was treated with Mg-REM spheroidizer have been studied. With the increase of copper content up to 2.0 wt.%, the following results were obtained: First, the ratio of residual magnesium content in the as-cast iron has been found to be increased, possibly due to the decrease of sulfur content in the melt. Thus, the morphology of graphite in the as-cast iron has been foun4 to be more nodular type. Second, the proportion of pearlite in the matrix has been found to be increased, however the matrix being pearlite with free carbide precipitates in the copper range of 1.2wt.% to 2.0wt.%.. Third, the tensile strength of the as-cast iron in the temperature up to 400℃ was increased.

본 논문은 한일 기계번역 시스템에 쓰이는 형태소 분석기 개선을 위한 고유명사 및 어절구조의 해석기법에 관한 연구이다. 고유명사는 사전에 동형이의어가 등록되어 있을 경우 잘못 번역될 수 있으므로, 번역대상 문장속에 있는 고유명사에 별도의 표시를 해두어 형태소 분석때 목적언어로 발음을 표기하고 괄호속에 원어로 표기해 주어 정확하게 번역한다. 또한 어절의 구조적 특징을 이용하여 어절을 이루는 위치에 올 수 없는 품사를 가진 단어를 제거해줌으로써 동형이의어를 처리할때 단어선택의 폭을 줄여준다. 본 논문에서는 고유명사에 표식을 넣어 주기 위한 자체 한글 입출력 처리기능을 가진 편집기를 내장하고, 사전의 구조를 한일, 일한 양방향 번역을 고려하여 재구성한다.

A Lactobacillus isolate was collected from the feces of a healthy Korean individual and named as Lactobacillus ruminus SPM0211. It was further characterized by subjecting it to an antibiotic resistance test and genetic analysis. In the antibiotic resistance test, all tested Lactobacillus spp. were classified as 'high resistance' for multiple antibiotics, such as isoniazid, ethambutol, cycloserine, and vancomycin. L. ruminus SPM0211 was classified as 'high resistance' for streptomycin also, while the other tested Lactobacillus spp. were classified as low resistance. This suggests that the antimicrobial spectra may be a good indicator in the discrimination of this strain among the tested Lactobacillus spp. In a polymerase chain reaction-random amplified polymorphic DNA (PCR-RAPD) analysis using the Microbial Uniprimer kit, L. ruminus SPM0211, and L. suebicus were clustered as a group with a 74.3% similarity level, suggesting that these two species are genetically related. Thus, our data suggest that the PCR-RADP method using the Microbial Uniprimer kit may be valuable in discriminating L. ruminus SPM0211 from other Lactobacillus spp.
