This experiment was carried out to provide some information on the change of dry matter productivity and feed value (forage quality) according to growth stages of late-maturing variety, Hwasan 101, Italian ryegrass (Lolium multiflorum Lam.) in Grassland and Forages Division, National Institute of Animal Science, RDA, Suwon from 2000 to 2002. In Suwon, booting, first heading, full heading and flowering stages of cv. Hwasan 101 were May 8, 18, 28 and June 3, respectively. Dry matter (DM) and total digestible nutrients (TDN) yields of Hwasan 101 were tendency to be increased by the progress of growth. DM yield in first heading stage increased 50% more than DM 4,818 kg/ha of booting stage, and also DM yield in full heading stage was increased by 26% of DM 7,244 kg/ha of first heading. Crude protein content was decreased gradually by the progress of growth, which were 18.32, 15.12, 12.58 and 12.36% in booting, first heading, full heading and flowing stage, respectively. Acid detergent fiber and neutral detergent fiber contents was increased and in vitro dry matter digestibility decreased gradually with progress of growth, but there was no difference between full heading and flowering stages. Considering DM yield and feed value of Italian ryegrass, the suitable cutting times seems between full heading and flowering stage.

This paper critically examines the existing discourses about 'relationship', a key element of social work practice and questingly examines Lao-tzu's work of Tao Te Ching, the book of way and virtue, as an alternative theoretical framework for social work relationship. Compared to current discourses of relationship beleaguered by either modernism or postmodernism, both of which are in the deadlock of binary perspective, the insights and vision in Tao Te Ching are successfully able to overcome the limits of them and provide new and profound way of thinking about human, society and their relationship. Especially core cannons crystallized by natural humanistic concepts for cosmos coupled with innate critical power against artificial manipulations of world can extend the horizon of understanding concerning the relationship between client and social workers and therefore provide a new and attractive roles in professional relationship. Moreover, opposed to usual images of Lao-tzu's ideas such as nihilism and passivity, alternative relationship of social work can play an important role of caring the disordered reality where Dao disappered and criticise the selfish desires of individuals and comport the broken-hearted minds in modern society. In addition, results of this paper implies that more extended study articulating ideas of Tao Te Ching with the social work practice would have lots of potentials to promote later researches in quest of 'Korean' social work practice.

For University students, reading is one of the important way of character education and career education that can give students the power to recognize and adapt to changes in society. The university supports the reading activities of university students in various ways, such as opening liberal arts courses related to reading or setting up required credits. In addition, it supports activities such as selecting the recommended book list for university students and providing the list. The purpose of this study is to analyze the problems of the current university's recommended book list and methods of using reading, and to propose improvement plans. To this end, using D University as an example, the current status of the recommended book list and reading discussion program were identified, and problems were investigated. In the current recommended book list, the subject area and list did not properly reflect the times, and the information on the provided list was very simple. Also, it was found that there was no suggestion on how to use the recommended book list. Through this, the recommended book list with the addition of bibliographic information and composition of the subject area was proposed. In addition, the reading discussion method was structured using Havruta.

In this research, the significance and practice on life of Dasan Jeong Yak-Young's family is reviewed. Articles, letter, poetry written by Dasan and research papers regarding to him are mainly referred for the research. Family life consciousness is divided into three sections in terms of family, food clothing and shelter life, and the economy of the family. Dasan's family life consciousness has been organized with self-management, temperance, thrift, sharing and giving for family and others. He emphasized practical efforts in daily life to realize sense of family life. First, Dasan sought self-managing and temperance as follows. He suggested attitude of careful speech and behavior, filial duty, peace within a family, reading, and training the body and mind including nice and independent temperament with being in good shape. Second, Dasan has been taught to practice the following to save money. It is important to be diligent, to live a simple life, to work hard on one's work, and to avoid extravagant behavior and heavy drinking. Third, Dasan emphasized to practice rational sharing and giving. It is to adapt to the environment, to live within one's means, to cope with difficult circumstances, not to have desire, and to practice giving. Dasan's family life consciousness includes the rules and values for implementing a welfare society. The welfare society is a society that shares good values and practices norms. In the future, the content of education should be developed to provide education about Dasan's family life consciousness. I hope this study can provide an opportunity that the moral teachings of Dasan can be handed down and practiced in relation to family life.

Classification on the group of Salix pseudo-lasiogyne growing in Korea, was conducted using cluster analysis, factor analysis, and principal component analysis. Thirty-six characters(Table 2) of the 5 basis species were measured. The phenograms and ordination plot showing the relationships between the species were made by applying the cluster analysis and principal component analysis. Five important factors, such as leaf blade width, number of right serration, angle of leaf apex, number of flowers in an ament, and the ratio of petiole length to width, were inferred from the rotated factor matrix, and their state values were presented in polygonal diagram. Salix pseduo-lasiogyne and S. babylonica were similarly correlated and linked in one group, S. dependens and S. matsudana for tortuosa were secondarily linked in the other group. S. koreensis appeared as an aliemated species from each of the two groups.

Kim Deuk-yeon(金得硏), who lived at the age of Chosun Dynasty, was the person who kept the parents's will of not serving as a government officias even though he had the ability of serving those positions. He made his composition at the Jisujeong(止水亭), a kind of pavilion which he had built, and the Sijo(時調) Sanjungjapgok(山中雜曲) is one of those compositions. This sugggestes that Sanjungjapgok has a close relation with the Jisujeong(止水亭) which he opreated on his own. So the purpose of this study is focused on analyzing the Sanjungjapgok based on his goal of operating the Jisujeong. The middle age of Chosun dynasty was the era when the pavilion had been prevail even to the average aristocrats who stayed just in local area. Kim Deuk-yeon seems to have had a great endeavor of operating his own pavilion; he had prepared to build Jisujeong for about 30 years. This resulted in his affection of the Jisujeong, which caused him to spend the last part of his life there. Sanjungjapgok consists of 49 pieces of peom and seems to have been written after compositing Jisujeongga(止水亭歌). Even though it has the same title, it doesn't have lots of relations for us to regard this as a Yeonsijo(聯詩調). But this also has the properties of Yeonsijo, whoch contatins 14 Yeonjaksijo(聯作時調) composed of Yeonsijo which has 2 to six lines. The subject of the Sanjungjapgok can be classified as a four major parts: appreciating the nature, study, gathering to make the poem, and taking a rest while satisfied with his own situation. These four properties reflect the function of the private pavilion. In the light of these four properties, I noticed that there were some contents dealing with the private pavilion. Given his social status, I was able to confirm that he had the considerable satisfaction with his life of operating the private pavilion, which was reflected by the Sanjungjapgok.

These studies were carried out to investigated effect of cultural environment and of plant growth regulator on Macrocarpium officinale NAKAI. The flowering and fruitage were significantly different with location of cultivated area. Generally, suitable cultivation area was the basin of the mountains of 200-400m above the sea. The diurnal temperature change of GURYE was greater than KWANGSAN. The soil conditions of main cultivation area were sandy loam of slightly acid (pH 6.2-6.6). Dry fruit weight without seed of Macrocarpium officinale NAKAl was increased 18% in primary treatment of Gibberellin W.P (200g/10a) 15days before and secondary GA3 50ppm(6g /10a) 15 days after flowering compared with the control.

This study was carried out to investigate the effect of temperature and daylength on the bolting of Angelica gigas Nakai for decreasing the rate of bolting.Seedlings were transplanted on early December to the PVC pot(1 /1000) in the greenhouse con­trolled the temperature of 15, 20 and $25^{\circ}C$, and the daylength of 8, 12, and 16hrs. Growth of aerial parts, bolting rate and root characteristics of A. gigas were investigated. Seedlings of A. gigas untreated with low temperature were nomally emerged, bolted and flowered in maturing stage. In this results, it was assumed that A. gigas was low sensitive to low temperature. The early growth stage was good at $20^{\circ}C\;and\;25^{\circ}C$, but the late growth was effective at $15^{\circ}C\;and\;20^{\circ}C$. The bolting rate was the highest at $20^{\circ}C$ while the root weight was the lowest. Although the bolting rate was high at $15^{\circ}C$, the yield was increased by the delay of bolting and flowering stage. The bolting rate was increased in the longer daylength and showed more sensitive to the daylength condition than to the temperature. Thus, A. gigas cultivated in gully field with cool temperature or under the shading light could be reduced could the bolting rate.

Elephant food(Amorphophallus konjac K.) have been utilized its tubers in workedmaterials for a health and diet food. The author supposed that it was increased the area of cultivation and demand. This experiments were conducted to select the proper covering material during winter in order to increase yield of tubers and decrease input by 2 year's continuous cultivation, also to verified ability of seed germination and to measured efficiency of photosynthesis of plant. The proper covering materials for wintering were rice straw and rice hull. These materials were covered at 5 cm thick and at field was promoted according to emergence appearing after winter. The yields were 5,790kg /10a at 4,730kg /10a, respectively. Yield increase was 120% and 80% than that of control. The seeds collected at August 22 were germinated about 84 percent, and it was not necessary to treatment of low temperature or germination-accelerated chemicals. The widest leaf area was ranged $1,218-1,438cm^2$ at October 20 and was varied. The efficiency of photosynthesis was highest at 65-95 days after leaf emergence. The line of broad leaf and high photosynthetic efficiency per unit area was greater compare with yield. Therefore, it was supposed that these characteristics will use a marker for selection for high-yielding lines.
