'NuRo (漏蘆)' is one of the crude drugs which has been used for removal of fever and skin disease. With regard to the botanical origin of 'NuRo', it has been considered to be Echinops species of Compositae, but there has no pharmacognostical confirmation on it. To clarify the botanical origin of 'NuRo', the anatomical characteristics of the root of Echinops latifolius and E. setifer were studied. As a result, it was clarified that 'NuRo' from Korea was the root of Echinops setifer.

This Paper describes Peak load forecasting technique of pole transformers with correlation equation. While customers are demanding safe energy supply, current correlation equation that is used for load management of pole transformers has some problems. To get accurate correlation equation. several correlation equation were examined using past data and nu data collected using the measuring instrument developed for this study. It was recognized that the quadratic equation was the most accurate for peak load forecasting from working electrical energy.

한국 고유종인 각시붕어 R. uyekii와 떡납줄갱이 R. notatus로부터 유도된 정교배 및 상반교배 잡종어류의 분자생물학적 동정을 위하여 핵에서 encoding되는 RAG-1 유전자의 염기서열 분석을 실시하였다. 분석된 863 bp의 염기서열 중 각시붕어와 떡납줄갱이 사이에는 총 13개의 위치에서 염기서열 변이가 탐색되었다. 잡종어류의 RAG-1 유전자 염기서열을 분석한 결과 모계와 부계의 염기서열 차이를 보인 13개의 변이 부분에서 부모의 염기서열을 다같이 반영하는 double peaks 패턴을 보였으나 정교매체(UN 유전형)와 상반교배체(NU 유전형) 간의 염기서열 차이는 관찰되지 않았다.

In this study, to develop balloon flower (Platycodon grandiflorum) leaves, which are not used as tea, a method of making green tea was referred to, and several physiological activities were analyzed using the balloon flower leaf tea with different times of roasting and rubbing. The highest total polyphenol and tannin contents were 33.02 mg GAE/g and 5.03 mg/g at two times of roasting and one time of rubbing, respectively. In the case of the total flavonoids, the RO3 + RU2, subjected to three times of roasting and two times of rubbing, showed the highest value, whereas there was no significant difference between the control and the other samples. Except for the green tea as a control, the RO2 + RU1 samples reported the highest antioxidant activity whereas it decreased with increasing number of times of roasting and rubbing. The color, lightness, and yellowness tended to decrease slightly as the number of increasing roasting and rubbing among the samples with no significant difference. All of these things together, to develop tea using the balloon flower leaves would be suitable with two times of roasting and one time of rubbing.

A simplified model for the so-called ACRT(accelerated crucible rotation technique) Bridgman crystal growth was considered in order to investigate the principal effects of the periodic variation of angular velocity. Numerical solutions were obtained for Ro=0.5, Ra=4.236*10$_{6}$ and E=2.176*10$^{-3}$ . The effects of spin-up process combined with natural convection was investigated as a preliminary study. The spin-up time scale for the present problem was a little larger than that observed for homogeneous spin-up problems. Numerical results reveal that over a time scale of (H$^{2}$/.nu..omega.$_{f}$)$^{1}$2/ the forced convection due to the formation of Ekman layer predominates. When the state of rigid body rotation is attained, natural convection due to buoyancy emerges as the main driving force and them the steady-state is approached asymptotically. Based on our preliminary results with simple spin-up, several fundamental features associated with variation of rotation speed are successfully identified. When a periodic variation of angular velocity was imposed, the system response was also periodic. Due to effect of mixing, the heat transfer was enlarged. From the analysis of time-averaged Nusselt number along the bottom surface the effect of a periodic variation of angular velocity on the interface location could be indirectly identified.d.
