  • Taxonomic relationships between some inulin containing plants such as Platycodon and Codonopsis have been investigated comparing their contents of inulin crystals, resin, as well as TLC patterns of saponins and acetylenes. Although Platycodon and Codonopsis have been known to be close in anatomic characters, the present results showed that there were significant differences between not only in the genus but also in the species.

  • 이 논문은 사진과 죽음이 맺는 관계를 고찰하면서 매체로서의 사진이 가진 독특한 특성이 이 관계에 어떻게 영향을 미치고 있는지를 살펴보고 실제로 사진이 죽음을 재현하는 여러 방식들의 구체적 사례들을 분류, 분석함으로써 죽음을 재현하는 사진의 사회적 역할을 이해하는 기회를 제공하고자 한다. 조사 결과, 죽음 사진은 영정사진, 사후사진, 재해 및 전쟁사진, 처형사진, 의학과 법의학적 사진으로 구분되며 애도와 추모, 저항과 투쟁, 통치와 지배, 폭로와 고발의 역할을 한다.

  • In order to estimate accurate originality of the important crude drugs, Gastrodia, Dendrobium, Bletilla and Cremastra spp. were investigated comparing their morphological, anatomical and physicochemical characteristics and antibacterial, antifungal activities. The results of the studies as follows: 1. In morphological and anatomical studies, Korean Gastrodia contained more mucilage duct and symbiotic fungi than imported Gastrodia. Korean Dendrobium contained starch grains but without starch grains in the imported Dendrobium from China enclosed with thicken silicified wall. The corm of Cremasta appendiculata contained raphides of bundles with mucilage while the bulbs of Tulipa edulis contained several various starch grains form. 2. In physiological and TLC analysis, crude drugs in Orchidaceae contained common constituents with fluorescence and much mucilage. 3. The EtOH extracts of Gastrodia, Dendrobium, Bletilla, Cremastra showed antibacterial activities against B. subtilis and E. coli (Dendrobium>Gastrodia>Bletilla>Cremastra). But, no antifungal activities against C. albicans, A. niger were observed.

  • In order to clarify the originality of several Alisma Rhizomes, we investigated the differences of their morphological, anatomical and physiochemical characteristics. Morphological observation shows the variability of Alisma shape and quality. The diversities in morphological shapes and qualities of tuber were observed among different origins. Chinese product looked like corm shape, but korean's irregular shape. The microscopic observation of korean Alisma revealed the presence of irregular vascular bundle which was scattered transversely and longitudinaly, which was different from that of the rhizome. This facts suggest that the portion of crude drug in Alisma should be the corm rather than the rhizome. In the physicochemical differences, chinese Alisma contains larger amount of mineral elements such as K, Na and Ca than korean Alisma. On the contrary, protein contents in lyophilized powder of aqueous extracts in korean Alisma rhizome was significantly higher than chinese Alisma rhizome. The leaves and stems contained larger amount of Ca and Na than tuber, and may be used as the osmotic diuretics for chinese traditional medicine.

  • According to the result about 'San Jiao(三焦)'recorded on "Yellow Empero's Canon Internal Medicine Ling Shu(黃帝內經 靈樞)", we achieved following results. 1. As we consider the concept of 'San Jiao' recorded on "Ling Shu", in early time, it was related to bladder(膀胱) and there was no divided concept into 'Shang Jiao(上焦)', 'Zhong Jiao(中焦)' and 'Xia Jiao(下焦)'. Later, there was appearance of body metabolism concept in anatomic way and started to emphasize that stomach(胃) is the very beginning of digestion. This point then adjusted into the concept which the core theory of digestion and water metabolism begins with 'Zhong Jiao' and processes to 'Shang Jiao' and 'Xia Jiao' then it established the 'San Jiao' theory adjusted to the functional change than property change. Later as there is set theoretical structure of 'three Yin and three Yang(三陰三陽)', it included the concept of 'San Jiao' onto meridian system theory to complete as a theory. Finally, it completed the theoretical structure that 'San Jiao' runs water metabolism of circulation, body fluid and urine for body to produce blood and Qi to protect and provide nutrition to the human body. 2. From the point of each part, 'San Jiao' means all body composition factor related to the relation to the digestion and water metabolism to produce Qi and blood. Also, the details of entire function of 'San Jiao' tells that 'Zhong Jiao' intakes food and divides the clarity and turbidity of digested substances. The origin of this digestion and water metabolism lies at Xia Jiao. The clean substance including the mood and taste climbs via Shang Jiao. The vapor like substance climbed to Shang Jiao becomes 'defensive Qi(衛氣)' and controls body temperature and sweat by supporting and spreading the Qi by Shang Jiao. The liquid substance climbed to Shang Jiao becomes blood. The blood has stronger character as substance than defensive Qi so Zhong Jiao becomes the base and the way for the blood. The turbid Qi separated at Zhong Jiao passes large intestine and the solid substance is excreted and the liquid is absorbed into bladder. The Xia Jiao that controls this process controls the liquid state of water matabolism so control the urine with bladder. Therefore, 'San Jiao' can be understood as a general concept that controls entire water metabolism as a way of food, Qi and blood.
