Both benthic and planktonic foraminifera from Core 97-02 obtained in the northern East China Sea are quantitatively analyzed for reconstructing the paleocenography of late Quaternary. Since the earliest time of the core sediment (last not older than 18000 yr B.P.), the paleo-water depth has changed from less than 20 m to near 100 m at present, which is reflected by the benthic foraminiferal assemblages: before 14000 yr B.P., the water depth was shallower than 20 m; from 14000 to 7500 yr B.P., water depth was 20-50 m; and after 7500 yr B.P., water depth was 50-100 m. The foraminiferal fauna also disclose the water mass history: during the last glacial maximum, the water that dominated the study area might be the coastal water; at the end of the last glacial maximum(14000-9500 yr B.P.), the Yellow Sea Cold Water mostly affected this area; then it gave way to the Yellow Sea Warm Current after 9500 yr B.P.; and finally, the warm water has dominated this area since 9500 yr B.P. because of the westward shift and enhancement of the Kuroshio Current.

본 연구에서는 PSM, SMS, BS 8800, ISRS 체계 분석을 통하여 시스템 모두를 만족하는 안전$\cdot$보건 경영체제(SHMS)와 환경 경영 체제(ISO 14000)를 통합한 경영체제를 구축하였다. 또한, 통합된 안전$\cdot$보건 경영체제에서 표준 문서 형식을 만들 수 있는 가이드라인 모델을 제시하였다. 더욱이, 본 연구에서 개발한 통합 경영 체제는 화학공장에서의 물적, 인적 재원의 중복성과 비능률성을 감소시킬 수 있다.
