The effective components of the peony cultivar, Euseongjagyag and Youngcheonjagyag, which were the major cultivars of peony in Kyeongbuk area, were determined with HPLC and TLC. The paeoniflorin content in the root of Euseongjagyag were more than that of Youngcheonjagyag. The root of Euseongjagyag contained much albiflorin and Youngcheonjagyag contained much oxypaeoniflorin in comparision with albiflorin and oxypaeoniflorin contents in both cultivars of peony. Paeoniflorin contents in accordance with peony prodution regions were ranged from 2.15% to 4.08%, and paeoniflorin content of local cultivar of Euseong and that of Geochang were approximatly the same but that of Youngcheon was the lowest. Paeoniflorin content in the 18 accessions of peony cultivar which were collected from Kyeongbuk area and harvested on November 1993, were ranged from 1.41% to 5.30%. The 18 accessions of peony were classified with the HPLC chromatogram pattern of peony root extract into the three groups which composed with Euseong peony group(9 accessions), Youngcheon peony group (4 accessions) and Punggi standard peony group(5 accessions). High content of paeoniflorin WaS contained in peony root harvested in May and November. but low content of paeoniflorin was contained in peony root harvested in March and September.

The most important factor for the penetration performance of shaped charge is the liner design. By designing the liner to have properties of both high jet tip velocity and long jet break-up time, the better penetration performance could be acquired. Usually it is very difficult to satisfy above two conditions simultaneously. In this study, the liner with the shape of ogive was developed to have relatively larger jet mass compared to the conventional trumpet liner. The designed shaped charge showed jet properties with high jet tip velocity and long jet break-up time by using ogive liner and wave shaper. A commercially available hydro-dynamic code AUTODYN-2D was used for numerical analysis of jet formation. The flash X-ray test and the static penetration test were conducted to verify the results of numerical analysis.

혈관내에서의 비정상적인 혈소판의 활성화는 혈소판 응괴 또는 혈전 형성을 초래함으로서 동맥경화증, 심근 경색증, 혈전중등의 허혈성 질환의 발현에 직접 또는 간접적인 원인으로서 주목되고 있다. 본 연구자 등은 천연물로부터 혈소판 응집억제작용 물질의 개발을 목표로 하여 한약 또는 민간약의 형태로서 관련질환에 사용되어온 식물생약 약 40종을 검색하였으며 이들중 혈소판 응집억제작용을 갖는 식물로부터 작용 물질의 분리를 계속하여 오고있다. 본 실험에서는 작약을 메타놀로 추출하고 작용을 추적하면서 용매로 분획하였으며, 작용분획인 Et0Ac fr.으로부터 methyl gallate를 분리하였다. Methyl gallate는 오가피로부터 작용성분으로서 이미 분리 보고된 protocatechuic acid 및 artifact인 ethyl protocatechuate와 구조적으로 매우 유사하여 이들 analogs 수종에 대하여 작용을 비교 검색하였다.

Stem and petiol explants of peony culture turned to brownish black soon after placing onto medium and degenerated to death. Disroloration was caused mainly by ferrous and calcium cloride. Nitrate was a main factor for the death of culture. The culture damage was increased with the increment of the medium salt strength. A few latent axillary buds were elongated to shoots without forming callus.

Shaped Charge's penetration performance is depended on the shape of warhead and explosive, liner materials. The liner that manufactured to small homogeneous grain increase the penetration performance and decrease the deviation of penetration performance. This texture is obtained by forging process but, creating the process that remove crack and get small homogeneous grain is very hard. In this study, We success to get the homogeneous small grain texture through appling the most suitable process by DEFORM CODE analysis.
