  • This study was conducted to determine the optimum intervals of shelves and seed-tray layout in container for raising rice seedlings at automatic facility. The seedling characteristics were evaluated with 10-day to 20-day old seedling grown under the different intervals of nursery shelves and seed-tray arrangement in the containers. The plant height was increased as the shelf intervals in nursery containers from 17 cm to 23 cm. The difference in plant height was larger in seedlings seeded at May 10 than those at June 10 and in 20-day old seedlings as compared with 10-day old seedlings. The growth characteristics of seedlings was significantly varied with the layout intervals of nursery tray on the containers. The seedling height was shorter as the extension of layout intervals of the tray on the shelf of nursery containers, but the seedling quality was increased in the seedling which grown on the trays arranged at 3 to 5 cm intervals. The light intensity was remarkably different from the position of nursery tray in the container. The illumination intensity was the highest on the uppermost tray. However the seedling height was shorter as the raising of tray position from the lowest shelf to the highest it in nursery container. The best results based on the seedling characteristics was obtained from the seedlings which grown in the tray arranged at 3 cm interval on the ten-shelf container with 20 cm intervals.

  • As the representative medical scholar at the time of Geumwon(金元) Dynasty, Idongwon(李東垣) deepened and developed the meaning of the diseases on internal injuries. He also proposed the primordial Gi[原氣] and Eum-Fire[陰火] theory in the physiology and pathology. Idongwon(李東垣) defined the pathological metabolism of internal injuries as the hyperactivity against Eum-Fire[陰火] due to the lack of primordial Gi[原氣不足], and he suggested the deficiency of Gi[氣虛] in the Spleen and Stomach and the surge of seven modes of emotion as the causes of the Eum-Fire[陰火] hyperactivity. Additionally, he established the therapy principles of eliminating Heat with Sweet and Warm drug[溫熱藥] and raising yang and spreading fire[升陽散火] based upon the above mentioned pathological metabolism. The Eum-Fire[陰火] that was suggested by Idongwon(李東垣) indicates the Heat syndrome[熱證] developed by internal causes[內因], and the principle reason is the consumption of the Spleen and Stomach Therefore, it is important to recuperate the function of Spleen and Stomach in treating the disease symptoms caused by Eum-Fire[陰火], and the therapies of eliminating Heat with Sweet and Warm drug [溫熱藥] and raising yang and spreading fire[升陽散火] are the corresponding ones. However, since vital Essence could be lacked due to the consumption of Spleen and Stomach, the therapy of replenishing Eum has to be considered. Additionally, the damp removal therapeutic method also has to be considered since Damp could be stagnated by the loss of function in Spleen and Stomach. In other way, Eum-Fire[陰火] developed by the consumption of Spleen and Stomach is somewhat similar aspect to the premier Fire[相火] that is developed by the lack of Eum[陰虛]. But complications could be developed if therapies of enriching the Eum[滋陰] to suppress Fire and replenishing Eum[補陰] are mainly used to control the symptoms developed by the lack of Eum[陰虛]. Namely, the drugs used to replenish Eum[補陰] mostly have the heavy and turbid properties, which contrarily have the possibility to debilitate the functions of Spleen and Stomach by causing Dampness within a body. So, care must be made in their use.

  • This study was conducted to establish a domestic cultivation system of a newly introduced yam bean (Pachyrhizus erosus L.). Growth and yield were investigated in response to various cultural practices, such as seedling raising, planting distance, pinching, and flower pruning. Optimum conditions for raising of seedling were an average temperature of $22^{\circ}C$ for 30 days. Considering of the raising efficiency and the convenience of transplanting, 128 cells per tray was a suitable size. When pinching at a height of 120 cm from late July to early August, yield increased by 22% compared to no pinching. Flower pruning between late August and early September increased the number of tubers and tuber yield by 32% in comparison with no flower pruning. Yam bean seedlings planted at $50cm{\times}30cm$ spacing resulted in 30% yield increase as compared to wider spacing of $100cm{\times}30cm$. Our results thus suggested that the optimal combination of cultural practices ($50{\times}30cm$ planting distance, pinching at 120 cm height, and one time of flower pruning) increase profitability by 107%. All these results suggest high possibility of yam bean as a new income crop in Korea.
