This study was conducted to investigate the relationships between yearly variations of climatic factors and yearly variations of productivity in Alisma plantago L. In addition, correlation coefficients among yield and yield components were estimated. The data of yield and yield components were collected from the Statistical Year Book of Seungju province, Reserach Report of Seungju Extension Station of Rural Development Administration, and farmers for 10 years from 1983 to 1992. The meteorological data gathered at the Seungju Weather Station for the same period were used to find out the relationships between climatic factors and productivity. Yearly variation of the amount of precipitation in October and the minimum temperature in November were large with coefficients of variation(C.V.) of 106.44, 144.08%, respectively, but the variation of the average temperature, maximum temperature, minimum temperature from July to September were relatively small. Fresh weight and dry weight of roots vary greatly with C. V. of 30.62, 31.85%, respectivly. Plant height and stem length show more or less small C. V. of 5.51, 6. 26%, respectively and leaf width, leaf length, number of stems and root diameter show still less variation. Correlation coefficients between maximum temperature in November and plant height, stem diamter, number of stems, root diamter and dry weight of roots are positively significant at the 5% level. There are high signficant positive correlations observed, between yield and yield components. The maximum temperature would be used as a predictive variable for the estimation of dry weight of roots and number of stems. Simple linear regression equations by the least square method are estimated for number of stems $(Y_1)$ and the maximum temperature in November(X) as $Y_1=4.7114+0.5333\;X\;(R^2=0.4410)$, and for dry weight of roots$(Y_2)$ and the maximum temperature in November(X) as $Y_2=55.0405+14.3233\;X\;(R^2=0.4511)$

This experiment was carried out to investigate the growth characteristics and root yield with different harvesting times in Astragalus membranaceus. The growth of stem diameter. number of nodes. number of branches and dry weight of top plant were not affected in late harvesting time compare to early harvesting time. but stem height was increased by harvesting time. Otherwise root growth were effected by harvesting time in one and two years old plant. So, root length, weight of dry root and dry root yield were the most excellent until reached up to harvesting of 10th November. The content of methanol extract was not different between one and two years old plant, but that of different harvesting time was the most by harvesting time in mid November. It was suggested that the optimal harvesting time seems to be in mid November rather than in mid or late October.

The major purpose of this article is to analyze Lee Jema's idea of 'cultivating the self,' and therefore reveal a difference between his idea and 'cultivating and nurturing (the mind)' shown in traditional medicine and Neo-Confucianism. For this purpose, I first analyzed 'cultivating and nurturing (the mind)' of traditional medicine and Neo-Confucianism and showed Lee Jema's originality by studying philosophical foundations of Sasang constitutional Medicine. The idea of 'cultivating and nurturing (the mind)' is transcendental in that it pursues the unity between humans and the principle of natural changes or the Heaven. However, Lee Jema developed his own medical theory by analyzing an ontological structure of human beings and nature and life, and reinterpreting four beginnings on the basis of experience. He reinterpreted humans as a being in the structure of time and space, and relationships with others. In addition, he reinterpreted nature and life and four beginnings as the capability of wisdom and action and the function of mind and body. Therefore, he tried to overcome a transcendental thinking to aim for the unity of humans with the Heaven. Also, he discovered that the most important reason for disease is biased emotions (moral/private) because biased emotions influenced the function of mind and body. The causal relationship is the basis of his medical theory. Therefore, his idea of cultivating the self is focused on being careful not to make emotions biased. This reveals that even though Sasang constitutional theory came from the traditional medical theory and Confucian morality, it developed on a different philosophical foundation. In this regard, I tried to differentiate Lee Jema's idea of cultivating the self from 'cultivating and nurturing (the mind)' which aims for the unity between humans and the principle of changes or the Heaven.

The role of mind is very important in Xunzi's thought. The way is permanent rule of politics that is under the control of mind which is recognizing organ for both thinking and acknowledging things in his thought. Nevertheless the mind in Xunzi's thought has desire as an organ of body to be controlled. On the other hand, the mind has conflicting two fold aspects in the course of its recognition of things like storage and vacancy, movement and calmness, and two kinds of recognizing opinion against one object. And there are various evils in thinking system of mind. In a sense, the mind of human is to be cleaned and cultivated. Xunzi proposed managing energy and cultivating mind as a thinking system. Mengzi proposed to enliven vast-flowing energy and to cultivate mind through shortening desire, while Xunzi did managing energy and caring about mind for controlling other body systems and publicly recognizing things. In Xunzi's idea the mind in the recognition of things is similar to the water in bowl as a mirror for looking at any things, and thus it is imperative for us to sink grounds in mind for becoming good water mirror. In this need the grounds of human mind would be to be sunk and also the cultivation of it would be to be demanded. Ultimately there should need the recognition of mind that is cleaned and cultivated for brightly discovering the great principle and recovering the unchangeable way with a view to preparing the condition for national peace. This thesis, in this context, to approach the meaning of mind, its two fold aspects, and the necessity of it.

Several major agronomic traits of 4 isogenic lines for tillering(Kindred, Morex)were investigated under the different seeding rates and seedling mortality grown in the pots. The normal-tillering phenotypes had higher grain yield(46％) and leaf area index(56％) than their uniculm isogenic counterparts. The assortment rate(69％) and 1,000 grain weight(27％) in uniculm type were greater than the normal type. Uniculm plants were earlier in heading(4∼8days) and maturing(2∼3 days) dates compared with their counterparts. The grain yield was fitted to linear regression, ranged 0.659g to 0.5g per spike number. On increasing the seedling mortality rates, the grains per spike and 1,000 grain weight were slightly decreased, but the grain yield per plot was decreased markedly because of decrease of spikes per plot. The assortment rate, leaf photosynthetic capacity and reproductive tiller number were increased with increase of seedling mortality. The grain yield was largely dependent on the number of spikes per plot on occurrence of seedling mortality. For the uniculm genotypes to be introduced and bred into a present leading variety, the isogenic lines were precisely tested in the open field for a couple of years.

This study intends to understand Kobong's thought, especially the problem of Self-cultivation. Kobong, along with Toegye(退溪), is a major figure to understand Confucian ideas of Chosun in the 16th century. There has been a lot of research centered on Kobong's Four-beginnings(四端) and Seven-emotions(七情), but not much on the Self-cultivation of Kobong. Confucianism is basically to seek after actualization of Perfect Virtue(仁) and the way to be a sage, through the pursuit of self-discipline(修己 明明德) and social practice(安人 新民). The problems of Confucianism might be summarized as follows: interest and appreciation for the source of existence(知天/事天); harmony in relationships and practices(愛人/愛物); both of the above together. Therefore, Self-cultivation is to change the self, the subject of one's life, through the relationship between man and heaven. Kobong and Toegye had debated for about eight years(1559-1566) over the problem of human nature, especially emotion(情), and virtue and vice(善惡) fundamental position of Toegye is that the difference between Four-beginnings(四端) and Seven-emotions(七情) can be understood as emotion with qualitative distinction. By contrast, Kobong sees the relationship between Four-beginnings(四端) and Seven-emotions(七情) as that of total and partial. Discussion on the Four-beginnings(四端) and Seven-emotions(七情) is not restricted within the problem of logical analysis of concepts or theoretical validity, but come to a conclusion with the problem of Self-cultivation(修養). In this sense, Kobong tried to follow Neo-Confucian theory of human nature and self-cultivation, on the assumption of Confucian self-discipline and social practice.
