The purpose of this study was to develop a new preparation process of ginseng extract using high concentrations of ginsenoside $Rg_3$, a special component in red ginseng. From when the ginseng saponin glycosides transformed into the prosapogenins chemically, they were analyzed using the HPLC method. The ginseng and ginseng extract were processed with several treatment conditions of an edible brewing vinegar. The results indicated that ginsenoside $Rg_3$ quantities increased over 4% at the pH 2-4 level of vinegar treatment. This occurred at temperatures above $R90^{\circ}C$, but not occurred at other pH and temperature condition. In addition, the ginseng and ginseng extract were processed with the twice-brewed vinegar (about 14% acidity). This produced about 1.5 times more ginsenoside $Rg_3$ than those processed with regular amounts of brewing vinegar (about 7% acidity) and persimmon vinegar (about 3% acidity). Though the white ginseng extract was processed with the brewing vinegar over four hr, there was no change for ginsenoside $Rg_3$. However, the VG8-7 was the highest amount of ginsenoside $Rg_3$ (4.71%) in the white ginseng extract, which was processed with the twice-brewed vinegar for nine hr. These results indicate that ginseng treated with vinegar had 10 times the quantity of ginsenoside $Rg_3$, compared to the amount of ginsenoside $Rg_3$ in the generally commercial red ginseng, while ginsenoside $Rg_3$ was not found in raw and white ginseng.

In the 19th century, Chosun mathematicians studied the most distinguished mathematicians Qin Jiu Shao(泰九韶), Li Ye(李治) Zhu Shi Jie(朱世傑) in Song(宋), Yuan(元) Dynasty and they established a solid theoretical development on the theory of equations. These studies began with their study on Si yuan yu jian xi cao(四元玉鑑細艸) compiled by Luo Shi Lin(羅士琳). Among those Chosun mathematicians, Lee Sang Hyuk(李尙爀, $1810{\sim}?$) and Nam Byung Gil(南秉吉 $1820{\sim}1869$) contributed prominently to the research. Relating to Si yuan yu jian xi cao, Nam Byung Gil and Lee Sang Hyuk compiled OgGamSeChoSangHae(玉監細艸詳解) and SaWonOgGam(四元玉鑑), respectively and then later they wrote SanHakJeongEi(算學正義) and IkSan(翼算), respectively. The latter in particular contains most creative results in Chosun Dynasty mathematics. Using these books, we study the relation between the development of Chosun mathematics and Si yuan yu jian.

This study conducted to investigate the effects of feeding Fermkito 50 on the egg production and egg quality hens. One hundred forty four, 50 weeks old ISA brown commercial layer, were used in a 28 d growth assay. Dietary treatments included 1) control(basal diet), 2) FERMO.5(based diet+0.5% Fermkito), 2) FERM1.0(basal diet+1.0% Fermkito), 3) FERM+YU(basal diet+0.5% Fermkito and 0.05% yucca extract). Overall (d 0 to 28), egg production tended to increase as the concentration of Fermkito 50 in the diets was increased without significant difference(P〈0.05). As adding level of Fermkito 50 increased in the diets, egg weight tended to increase. Laying hens fed FERM+YU diet were higher egg weight than laying hens fed control diet(P〈0.05). Egg shell breaking strength was not influenced by Fermkito 50. As adding level of Fermkito 50 was increased in the diets, yolk color tended to increase. Laying hens fed FERM+YU diet had improved egg yolk index compared to laying hens fed control diet. Total-cholesterol of egg yolk in FERM1.0 and FERM+YU treatments was significantly decreased compared to that in control diet(p〈0.05). Total-cholesterol and triglyceride concentrations in serum tended to increase as the concentration of Fermkito 50 in the diets was decreased(P〈0.05). Also, HDL-cholesterol concentration in serum with FERM1.0 and FEUM+YU treatments was significantly higher than control diet(P〈0.05). However, LDL-cholesterol concentration in serum with FERM1.0 and FERM0.5+YU treatments was significantly lower than control diet(P〈0.05). In conclusion, supplemental Fermkito 50 in laying hen diets can be used to improve egg quality.

Background: Liu-Yuan-Lei(陸淵雷) said that a medical record is both the marks of treatments and arts made by a excellent practitioner and the essence of TCM(Traditional Chinese Medicine). Jiang-Guan(江瓘) also said that reading medical records is one of the best way to develop one’s abilities If curing a disease without perfect clinical practice. Objectives: study on the special treatment about metrostaxis(崩漏) based on the Yi-Da-Gan(易大艮)’s medical records. and study on the differentiation of abnormal symptoms and signs about cold syndrome with pesudo-heat(眞寒假熱) based on the Yu-Chang(喩昌)'s medical records. Methods: First, read and study the medical records on metrostaxis(崩漏) of that made a profound study by Yi-Da-Gan(易大艮) and cold syndrome with pesudo-heat(眞寒假熱) of that made a profound study by Yu-Chang(喩昌). The next, write a paper on results and conclusions. Results and Conclusions: First, Yi-Da-Gan(易大艮) insist that must control the Qi under the blood disease conditions, taking the case of metrostaxis(崩漏). Secondly, we must study more on estimating the changing condition of Qi and the blood as time goes by, also study on the pulse and pulse condition in the four seasons(四時脈). Thirdly, Yu-Chang(喩昌) insist that be more careful in differentiation of symptoms and signs, taking the case of cold syndrome with pesudo-heat(眞寒假熱). Fourthly, Yu-Chang(喩昌) give an example that in condition of cold syndrome with pesudo-heat(眞寒假熱), sometimes, the pulse and pulse condition can be strong.

This study was conducted to investigate allelopathic potential of various crosses of rice cultivars using their inhibitory effect on barnyardgrass growth under field conditions, and to determine PAL activity and phenolic compounds involved in phenylpropanoid pathway from selected crosses of rice cultivars. Under field conditions, Kouketsumochi, Woo co chin yu possessed higher allelopathic potential inhibiting over 90% of barnyardgrass growth. Crosses of Kouketsumochi/Woo co chin yu, Dongjinbeyo/Kouketsumochi, Dongjinbeyo/Woo co chin yu showed over 80% inhibitory effects on barnyardgrass growth. The highest PAL activity, $63.46{\mu}kats/kg$ proteins was detected in Kouketsumochi which is the most important enzyme in phenylpropanoid pathway and also higher PAL activity in crosses with Kouketsumochi. Content of cinnamate was $2.64{\mu}g/g$ f.w. in Kouketsumochi which was 2 to 5 times higher than other rice cultivars tested, indicating that higher PAL activity resulted in more cinnamate. The similar trends in cinnamate content and PAL activity were observed in crosses of rice cultivars with Kouketsumochi.

Buddhism have affected Korea traditional education very much. Sam Guk Yu Sa is a book which includes the public disposition grounded on world view of Buddhism. In the wide scope, the public disposition relates to their cultivating education. This paper reviewed cultivating education grounded on John Dewey "experience-learning" model about the Buddhistic public disposition appearing in Sam Guk Yu Sa. "Meaning-experience" as "adult-becoming" appearing in Sam Guk Yu Sa shows a strong characteristic of cultivating education when we see on a creative horizon in the Buddhistic world. Dewey-Deleuze's cultivating education which modernizes the theory of John Dewey meets at the place of the public disposition and three fables of Sam Guk Yu Sa grounded on the Buddhistic world. This could open possibility to interpret the cultivating theory of Korea traditional thought and western educational theory with interdigitation. Fables of Sam Guk Yu Sa dealt with growth and maturity of the public from Buddhist monk to folk wishes to achieve Bulgukto(佛國土; the land with Buddha) through the process of cultivating education which leads to "impulse-observation-knowledge-determination." In these series of process for "adult-becoming," life itself possesses characteristic of cultivating theory. In this respect, fables of Sam Guk Yu Sa shows Korea traditional cultivating theory and can be a role of a discourse book for cultivating educational theory which could relate to western educational theory.
