This study was carried out to determine the effect of establishment of organic pasture by hoof cultivation with Korean black goat on productivity of grassland and properties of soil. This study was conducted from August, 2005 to September, 2008 at Cheonan, Korea. Experiment was designed composing with 4 treatment : Standard (Control, T1), Grazing after application of cattle manure (T2), Application of cattle manure after grazing (T3), Application of cattle manure at half of grazing (T4). The establishment ratio of pasture in control treatment increased significantly as compared with that of organic treatment(p<0.05). The yield of dry matter (DM) of pasture in control treatment increased significantly as compared with that of organic treatment. The contents of crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF) and dry matter digestibility (DMD) of pasture were not influenced by cattle manure and grazing method. Grasses coverage ratio in grassland in second year after grassland development were higher than that of first year. The contents of organic matter (OM) and $P_2O_5$ in soil samples collected in organic treatment at the end of the experiment were higher than those of control. However, The pH, and the concentrations of CEC (Ca, Na and Mg) in soil samples collected in organic treatment were hardly influenced, as compared with those at the beginning of the experiment. This study suggests that the grasses and legumes coverage ratio in grassland can be improved by suitable pasture management.

This thesis is about Chungyongkugyongyonui(中庸九經衍義) by HoiJae Lee Eon Jeok (1491~1553). As many know, he was one of the philosophers representing the 16th century who played a great role in making the Zhūzǐ's Neo-Confucianism settle down in Joseon society through the dispute on TaeGeuk (太極) against Cho Han Bo (?~?). He was also the scholar who firmly established the theoretical system of the Idea for Proper Governance (至治主義). The Supplementary Explanation to the Chapters and Phrases of the Great Studies (大學章句補遺) and the Transcript of Nine Annotations on the Middle Way (中庸九經衍義) were written to argue his thoughts of the Idea for Proper Governance shown in the Great Studies (大學) and the Middle Way (中庸). He said that the Great Studies was more specific in the clauses for the justice of training oneself while the Middle Way more detail in the clauses for the justice of governor. That is, he thought that those books were in the relation of the in-and-outside, so that he argued that kings should take both justices of such for governance. Especially the Transcript of Nine Annotations on the Middle Way was written by following the way of the Annotation Transcript of the Great Studies (大學衍義) by Jin Deok Su (眞德秀), a scholar of Song Dynasty and the Supplementary Explanation to the Annotation Transcript of the Great Studies (大學衍義補) in order to make the King MyeongJong of that period realize the Proper Governance of the Two Great Emperors and Three Great Kings of Ancient China, which greatly influenced the Ten Figures of the Studies for the Great Man (聖學十圖) by ToiGye Lee Hwang and the Abstract of the Studies for the Great Man (聖學輯要) by YulGok Lee Yi.

To clarify the direct effect of potassium and interactions with nitrogen and phosphorus on the yield of pasture plants, fertilizer experiment with varied levels of potassium and nitrogen treatment to grass single seeding, legume single seeding and grass-legume mixed seeding, was conducted for three years from 1977 to 1980. The summary of obtained experimental result may be described as below: 1. Potassium application, at any level of amount, did not show its effect to the establishment of plant population, however potash application responded to help winter hardiness at grass single seeding plot. 2. Potassium effect on the fresh yield at grass single seeding was distinct however, not clear effect was observed at legume single seeding and grass-legume mixed seeding plots. 3. For drymatter yield, the highest yield at legume single seeding was recorded 1.152 Kilograms per 10a are at treatment #4 and the highest yields of grass-legume mixed seeding and grass were recorded 1,093 kilograms (Treatment #3) and 834 kilograms (Treatment #5) respectively. 4. In observation of plant succession, they were found that orchardgrass and tall fescue have increased at grass single seeding plot and Alfalfa was dominant over 90 per cent of plant population at legume single seeding and grass-legume mixed seeding plots. It seems that potash effect was distinct in increasing orchardgrass population. 5. The results of this experiment shown that the maximum yield from grass single seeding was obtained at the plat where applied 20-20-30 kg/10a, $N-P_2O_5-K_2O$ and the maximum yield from legume single seeding was obtained at the plot applied with 8-20-20 kg/10a, $N-P_2O_5-K_2O$. 6. Fertilizer cost for producing one kilogram of dry matter in this experiment was lowest at treatment #1 of grass-legume mixed seeding and highest at treatment #5 of grass single seeding. The largest gross income was obtained from the plots where phosphate application was omitted. 7. From the results of this experiment, it may be recommended that economically optimum fertilizer application for grass single seeding will be 20-20-20- kg/10a, $N-P_2O_5-K_2O$ and for legume single seeding and grass-legume mixed seeding will be 8-20-20 kg/10a, $N-P_2O_5-K_2O$.

According to the rapid increase of foreign immigrants, South Korea recently has grown more and more interested in the acceptance of cultural diversity in diverse fields at the whole society. Korea Library Association also has sought the way of multicultural service for foreign immigrants in libraries and many previous researches has suggested those. This paper examines the ways in which small community library functions for foreign immigrants, analyzing on the case of multicultural library located in Wongok-dong, Ansan-si, where about 80% population of residents are foreign immigrants. Ansan multicultural library has two functions in the community. One is the educational place for helping immigrants' settlement and adaptation of South Korea. The other is the cultural place for social integration between immigrants and South Koreans based on mutual understanding and communication. Ultimately this paper shows how values small library in the community has significantly for foreign immigrants.

Two experiments were conducted to investigate the response of chitosan supplementation in diet on the major economic traits of broiler in two different breeds. In the both experiments, the Arbor Acres and Ross breeds were used as experimental stocks and two groups were assigned in each breed. The control group birds(CON) were fed with basal diet only and the experimental group birds(EXP) were fed with basal diet added with 10.5mg chitosan/bird/day. The chitosan was supplied to birds from day-old in experiment 1 and from 15-day-old in experiment 2. In experiment 1, the mean body weight at 35-day-old were significantly(P〈0.05) heavier by 121.2 g and 243.7 g in the EXP groups than in the CON groups of Arbor Acres and Ross, respectively. Whereas, the mean body weights at 35-day-old in experiment 2 were lighter by 91.7 g and 70.2 g in the EXP groups than in the CON groups of Arbor Acres and Ross, respectively : however, the comparisons between breeds in the mean body weight at 35-day-old did not show significant difference in each other in both breeds. In the mean feed conversion ratio of Arbor Acres from 14 to 35-day old in experiment 1, it did not show significant difference between EXP and CON groups although the feed conversion ratio of the EXP group of Ross was significantly higher(P〈0.05) than the CON group. In experiment 2, the feed conversion ratios from 14 to 35-day-old did not show significant differences between the two breeds. The percentage of mean abdominal fat depositions of EXP groups in both breeds In experiment 1 were significantly(P〈0.05) higher than those of CON groups. And the percentage of mean abdominal fat deposition of Ross was significantly(P〈0.05) lower than that of Arbor Acres. In experiment 2, the percentage of mean abdominal fat depositions did not show significant difference between EXP and CON groups in both breeds. Whereas, the interaction effects between breed and experimental groups on the above economic traits did not show significant in both experiments.

Biological control of aphids using "banker-plants with the parasitoiid, Aphidius colemani Viereck (BPAC)" was carried out on cucumber in greenhouse. The BPAC consisting of barley seedlings infested with Schiraphis graminum (Rondani) enhanced the early establishment of Aphidius colemani in the greenhouse and prolonged the control of Aphis gossypii on May 8, 2001 The BPAC was placed in the greenhouse at transplanting at the rate of 1 per 30 m2 of cucumber. Although good control effect was gained until early August after placing banker plants on May 9, the effect after then because of high temperature. The aphid population on cucumber in control plots reached to a peak on June 26, and decreased because of entomopathogenic fungus for rainy season of July, and increased again to a very high population on August.

These studies were conducted to evaluate the Properties of lactic acid Producing bacteria(LAB), isolated from broiler and laying hens cecum and select the optimum strains to improve the performance, environment of poultry house, immunity, and intestinal microflora of broiler and laying hens. In experiment I , 23 LAB strains were isolated from broiler and laying hens cecum as a colony form. Six strains were selected by acid tolerance, bile salt tolerance, viability, enzyme release, antagonism, and antibiotics susceptibility. In Experiment II, selected LABs from Ex. 1 were conducted to investigate the effects of feeding various Lactobacillus on performance, nutrients digestibility, intestinal microflora, villi development and observation of epithelium surface, blood chemicals and fecal noxious gas of broiler chicks. One thousand eighty one day old broiler chicks were fed into Lactobacillus crispatus avibrol(LCB), Lactobacillus reuteri avibro2(LRB), Lactobacillus crispatus avihen1(LCH), and Lactobacillus vaginalis avihen2(LVH) at the level of 10$^4$ and 10$\^$7/cfu/g diet. Weight gam of chicks fed Lactobacillus tended to increase from the first week and was higher from 50 to 100g in Lactobacillus treatments than control. Feed intake and feed conversion were not statistically different of all treatments. Dry Matter digestibility of Lactobacillus treatments was prone to improve compared to that of control, but was not significantly different. Protein and Ca digestibility were also tended to improve in Lactobacillus treatments relative that of control. Lactobacillus treatments showed improved tendency in crude ash and fat compared to those of control, whereas phosphorus digestibility was not consistency. Nutrients digestibilities of bird fed LCH were superior to those of other treatments, It showed significantly higher in Ca and P digestibility than control(P〈0.05). Total Lactobacillus spp. of birds fed various Lactobacillus was significantly higher in illeum for five weeks(P〈0.05), but was not different at cecum. Yeast was thought to be not completely attached to intestinal lumen for one week. However, total number of yeast was significantly increased in cecum and illeum of three weeks old chicks (P〈0.05). The number of anaerobes exhibited to tendency the increase in Lactobacillus treatments from one week old of age at both ileum and cecum.
