본 연구는 우리나라 기업의 구성원이 지각하는 조직문화 가치변수 변화 추세와 조직성과의 관계에 관해 살펴본다. 이를 위하여 본 연구는 한국의 상장기업 240개 표본을 대상으로 실증분석을 하였다. 연구결과, 먼저 시간적 흐름(IMF 이전과 현재시점)에 따라 구성원이 지각하는 각 조직문화 가치 변수의 평균치는 “구성원 노동력의 중요성”에 관한 조직문화 가치 변수를 제외한 나머지 조직문화 가치 변수의 평균치는 변화된 것으로 분석 되었다. 세부적으로 우리나라 기

Characteristics of plasma nitriding and nitrocarburizing for steam treated sintered steels were studied. Fe-0.8%C powder containing Ni, Cu were sintered at 112 and steamed at 52. Temperature of plasma nitriding and nitrocarburizing was varied from 50 to . Gas mixture of nitriding was set at : =80:20 (vol.%), but was added 1~2 vol.% for nitrocarburizing. Steam treatment for sintered steels brought not only the formation of oxide layer but also decarburizing near the surface. Decrease in hardness near the surface resulted from the formation of ferrite due to decarburizing. Thus, the low hardness was recovered not with plasma nitriding but with plasma nitrocarburixing. Wear resistance properties of steamed specimens and ni-trocarburized specimens were better than those of nitrided specimens according to the pin-on-disk wear test. On the other hand, the fatigue life of steamed specimen was shorter than that of nitrocaiburized specimen.
