필자는 남조약부민가의 분석을 통하여 문학작품과 세계관의 상관관계를 간략하게 고찰하고 남조약부민가의 전반적인 여성편향주의가 비극적 세계관과 어느 정도 연관성을 지님을 토구한 바 있다(김상호, 1986). 그러나 당해 글에서는 민가체 형식을 지닌 시가의 주요한 검토부분인 화자의 문제를 도외시한 오류를 범하였으며 남조약부민가에서 발견할 수 있었던 세계관의 문제를, 일반성을 배제한 채, 당시 사회의 특수한 산물인양 간주함으로써 여성적 표현을 과대 해석하는 그릇된 시각을 노정하였다.
도열병균에서 추출한 Cx 효소의 순화 및 특성에 관한 연구
김상호,김은수 한국균학회 1982 韓國菌學會誌 Vol.10 No.2
The (NH₄)₂ SO₄, (70%) treated crude enzymes from the culture filtrates of the C-7^(+1) strain of Pyricularia oryzae which was grown on 2% CMC (carboxymethyl cellulose) for 8 days at 28℃, were chromatographied on Sephadex G-150 and DEAE-Sephadex A-25 columns. From the chromatography, three fractions of CMCase(C_x) was examined using Na-CMC as substrate. The C_x enzyme activity was optimal at pH 6.0 and 40℃, stable up to 40℃. The values of Km and Vmax of the enzyme were 2.8 × 10 mM and 5.9m moles/hour, respectively. The molecular weight determined by Sephadex G-150 column chromatography was around 80,000. Approximately sevenfold purified C_x enzyme gave a single protein band on the polyacrylamide gel electrophoresis.
급속응고된 비정질 Zr-Be 합금 용가재를 이용한 Zircaloy-4의 브레이징 특성
김상호,고진현,박춘호,김성규,Kim, Sang-Ho,Go, Jin-Hyeon,Park, Chun-Ho,Kim, Seong-Gyu 한국재료학회 2002 한국재료학회지 Vol.12 No.2
This study was conducted to investigate the brazing characteristics between Zircaloy-4 nuclear fuel cladding tubes and bearing pads with filler metals of amorphous $Zr_{1-x}Be_x$(0.3$\leq$x$\leq$0.5) binary alloy, in which they were produced in the ribbon form by the melt-spinning metod. The crystallization behavior, stability, hardness and micro-structure of brazed zone were examined by X-ray diffraction, differential scanning calorimetry, micro-Vickers hardness test, optical microscopy, and transmission electron microscopy. $Zr_{1-x}Be_x$(0.3$\leq$x$\leq$0.4) amorphous alloys were crystallized to $\alpha$-Zr with increasing the temperature, and the rest were transformed to ZrBe$_2$at higher temperatures. On the other hand, $Zr_{1-x}Be_x$(0.4$\leq$x$\leq$0.5) amorphous alloys were crystallized to $\alpha$-Zr and ZrBe$_2$, simultaneously. The thickness of the layer brazed with amorphous alloy was increased with increasing the beryllium content due to the higher diffusion of Be. The morphology of brazed layer with PVD Be filler metal showed dendrite while that brazed with amorphous alloys appeared globular. Micro-Vickers hardness of brazed zone increased as the beryllium content of filler metal was decreased.
