  • The medicinal plants have been used as drugs for thousands of years and many of them are used in traditional medicines. How long are these medicinal plants used as drugs\ulcorner Ebers papyrus (BC 1550) is one of the oldest documents which described more than 700 kinds of herbal drugs. Some of herbal medicines described in the papyrus are familiar and ‘Opium’ is a good example. Some of the drugs described in the papyrus are hardly recognized as drugs by the standard of present day. We can trace back the history of medicinal plants from quite different approach. The investigations on group behavior of chimpanzees in Africa by ‘The Primate Institute of Kyoto University’ has revealed that chimpanzees suffered illness take specific plants which are not taken as daily food stuff. The chemical analysis clarified that the plants contain very bitter constituents and suggested that chimpanzees take medicinal plants to cure their illness. It is worth to note that young chimpanzees just learn what elder ones take when they suffer illness, but elders never teach to their children! It is no doubt that the chimpanzee's medicinal plants were found by random, and try and error screening. The medicinal plants found in this study have been used as herbal medicines by the peoples in the region.

  • 2009년 3월부터 10월까지 경상남도 합천군일대의 자원식물분포조사를 수행하였다. 본 조사를 통해 확인된 조사지역내의 소산 관속식물은 82과 292속 427종 4아종 49변종 9품종으로 총 489분류군으로 확인되었다. 조사 지역에서 분포하고 있는 식물의 자원 유용도를 분석한 결과, 식용자원식물이 187분류군, 섬유용 자원식물이 9분류군, 약용 자원식물이 137분류군, 관상용 자원식물이 52분류군, 초지 자원식물이 126분류군, 공업원료자원이 2분류군, 염료용 자원식물이 112분류군, 목재용 자원식물이 16분류군, 용도가 밝혀지지 않은 식물이 134분류군로 구분되었다 특기할만한 식물로는 한국 특산 관속식물이 총 18분류군, 환경부지정 특정식물종이 33분류군, 희귀식물은 2분류군으로 각각 조사되었고, 귀화식물은 44분류군으로서 전체분류군의 약 8.9%를 차지하였다. 한편 조사지역의 식생은 비교적 양호한 편이었으나, 레저시설이 형성되거나, 중계소, 사찰 등으로 인한 임도와, 저지대의 많은 농경지로 인해, 귀화식물의 분포가 빠르게 확산될 우려가 크므로 이에 따른 적절한 조치가 필요할 것으로 판단된다.

  • Differential pressure type level measuring systems have been using widely for industrial applications like drum level measurements in power plants. Because of difficulties in specific gravity compensation for vapor and liquid inside the vessel and the sensing lines, this type of measuring systems reveal significant measuring error. In this paper, the major reason causing errors on the differential pressure type level measurement is analyzed and a method of more accurate calculation for specific gravity compensation is introduced.
