The fashion of late Yi dynasty had explored a possibility of new fashional beauty from its own experiences throughout the history of Korean fashion excluding any interference of foreign fashions, and brought out some characteristics ; first, the aesthetical value focused on the more human fashion resulted in the exposure of waist. This aesthetical change in the fashion of late Yi dynasty produced out results as follows ; the length and width of jacket became short and narrow maintaining the basic form, while the width of skirt became increased to be contrasted exceptionally with the upper coat. This mode of fashion reveals the transitional movement from the emphasis on balance to that on unbalance in the late period of Yi dynasty. But regarding the fact that the proportional change by the ways of putting on skirt became to be similar to the golden ratio, we can see many examples throughout the folk paintings by Shin Yun bok, we find that the fashional beauty of that age pursued ideal harmony and unity all the time being in spite of its tendency toward non-refinement. Second, we see another peculiarity in the mode of woman's fashion from the paintings by Shin Yun-bok who always depicted the hu-man nature frankly. For example, the jacket became shorter to emphasize lady's slim waist, and underwears began to be exposed after the upper part of skirt had been to expose lady's waist while the bottom line pulled up highter than before. Thus, as the function of robe had changed from a mere means of covering into an expression of beauty, the fashion of late Yi dynasty began to express a perfectly new beauty possessing an erotic mood and sensu-ality of a woman, which was its inner aesthetic need. Third, this emergence of new fashional beauty made the mental value of man and the aesthetic views of that time quite different from the previous ones, and finally there came various expressions of a new beauty. There-fore, the woman's fashion of late Yi dynasty is noted for the exposure and emphasis on the body line of a woman after the aesthetic view-point had changed of time toward pragmatism and humanism, while upholding the traditions of Korean clothes and pride for the nation. And our ancestors realized very Korean fashional beauty by pursuing the expressional ways of gentle, indirect emphasis upon the feminine and natural beauty to exclude and ar-tificial, direct and straightforward exposures and images.

Objectives : In order to find how reference books of Yi Xue Ru Men reflect the classification and criterion for low back pain(LBP). Methods : From reference books of Yi Xue Ru Men, select the texts on classification and criterion for LBP. Results : According to the causes of LBP, Chao Yuan Fang(巢元方) in Sui Dynasty assorted to 5 types of LBP at the very first. Chen Wu Ze(陳無擇) in Song Dynasty made 7 divisions by external, internal, and non-external, non-internal causes. According to the pulse of LBP, Yan Yong He(嚴用和) first categorized 4 groups, Zhu Zhen Heng(朱震亨) added another 4 groups. Aside from this standard, Zhu(朱震亨) adopted the cause standard. Depending on Yunqi(運氣), Lou Ying(樓英) classified 5 types. But his classification had been not adopted by any TCM books. According to symptom of 6 varieties(六變), Zhang Jie Bin(張介賓) assorted external(表), internal(裏), deficiency(虛), sufficiency(實), cold(寒) and heat(熱), add 2 groups besides them. But his categorization did not reflect Yi Xue Ru Men. Li Chan(李梴), the author of this book chose causes and pulse classification standards that Zhu Zhen Heng had adopt. Conclusions : In the side of classification and criterion for LBP, Li Chan first divided 2 group, external and internal injury. After it he subdivided both groups to 10 subgroup. His classification is similar to Chen(陳無擇)'s, but actually followed the classification for external and internal injury that was invented by Li Dong Yuan(李東垣).

Objectives : This study aimed to reveal the characteristics of formulas in "Key to Therapeutics of Children's Diseases" by analysis of crude drugs that constitute formulas. Methods : To analyze the formulas, We classified the formulas to presenting symptom classification. And within that categories, the crude drugs in formulas were diagrammatized. Results : After those analyses, we brought a conclusion as like these. 1. The formulas classified into some categories that include chronic consumption disease, parasitization, digestive system disease, febricity, infectious disease, respiratory disease, skin disease, infirmity and etc. 2. We analyzed the characteristic of formulas by categorization of crude drug combination. In this way, we recognized that Qian Yi(錢乙) frequently used cold crude drugs unlike the trend of S$\grave{o}$ng(宋) dynasty doctors. 3. The prescription that described in "Key to Therapeutics of Children's Diseases" can be found in "Treasured Mirror of Eastern Medicine(東醫寶鑑)" and the other books on posterity. Conclusions : Through these researches, we verified that Qian Yi affect cold herbal and mineral drugs. This tendency of Qian Yi have an effect on the Nourish yin school. And several decades of formulas of "Key to Therapeutics of Children's Diseases" contain in part of pediatrics on "Treasured Mirror of Eastern Medicine". We reconfirmed that Qian Yi affected profound influence on the development of pediatrics and Nourish yin school.

The modern trend in costumes, influenced by postmodernism, is to use of various patterns and images borrowed from diverse cultures of many ethnic groups. The Yi tribe studied in this paper is miner ethnic group in China, whose traditional costume is very splendid and modern. In addition, its embroidery or $appliqu{\acute{e}}$ pattern have a high artistic value in that its shapes are diverse, splendid and each one has its own peculiar elegance. As for the research method, I examined the Yi tribe's history, culture, traditional costumes and patterns through related books, research papers and inter web sites. As for the result, the Yi tribe's costumes consisted of a jacket, trousers or a skirt, an apron and a belt. Although the favorite color of the costume is black color, there are splendid embroidery or $appliqu{\acute{e}}$ decorations with the colors of red, yellow, green and purple on the chest or shoulder part of a jacket, the adjusting lines, cuffs or a part of a trousers and aprons. Patterns in their traditional clothing also show details that depict traditional cultural ideas that have long been formed in various fields, such as aesthetics, religion, philosophy, and customs. Moreover, most patterns displayed in their traditional clothing contain nature motifs and represent unique and beautiful designs; some patterns are even reminiscent of abstract paintings by modern artists. In conclusion, the traditional patterns of Chinese ethnic minorities reflect the values and notions of these races as well as decorative magnificence and a unique spiritual image. In other words, traditional patterns indicate the spiritual depth or symbolic stories beyond mere formative beauty.

Objectives : Medical treating with eating foods is one of important therapies in East Asian traditional medical knowledge and is referred as a therapy to treat diseases through foods. Since the food cannot be separated from ordinary people living, the medical treating with eating foods is a therapy with strong locality and contains many autogenous parts. Methods : Recently, the world is showing much interest for genetic resources, and the concept of intellectual property is rapidly expanding as the field of 'new knowledge property right' as well. Thus, the knowledge of medical treating with eating foods recently draws much attention in the economic aspect beyond the scholarly interest for traditional medicine. Here, I would like to summarize and report the contents related to medical treating with eating foods on "Yi, SeikKan experience prescriptions" which was discovered before. Results & Conclusions : First, medical treating with eating porridge on "Yi, SeikKan experience prescriptions" is classified into one with nonglutinous rice as the main ingredient and the other with other grains as the main ingredient. It is differently utilized depending on the nature of the grain. Second, medical treating with eating rice on "Yi, SeikKan experience prescriptions" was born from our nation's unique way of living and is classified into one way to eat rice mixed with ground medicinal herbs, another one to cook and eat rice with mixed grains and the other way to use as the external application. Medical treating with eating rice is assumed to replace the meal. Third, "food section" was given separately and discussed in this book. There were some parts different from existing medical knowledge due to the accumulation of experience using medicinal herbs. Fourth, we should pay attention to experience a book on medicine where vibrant medical information has been recorded in order to discover and process our traditional knowledge resources as a useful form.

The present study hypothesized that ratio between carcass traits components could be applied for the understanding of yield index in Hanwoo steer. A thousand data was generated based on average carcass weight (CW), loin area (LA) and backfat thickness (BT) of Hanwoo steer in December 2018 for analysis 1. Then yield index (YI) was calculated using newly established yield index equation. The correlation between yield index and each carcass traits was visualized. In the interaction between carcass traits components (LA, CW, BT) and YI, only the interactions including BT showed a regular pattern to YI. Then changes of YI according to ratio of carcass traits components were investigated. The observed interactions between LABT and CWBT were similar with Monod equation model. The changes of YI to LABT and CWBT were fitted to Monod equation, and yield constants (K1 for LABT; K2, CWBT) of each equation were calculated as 0.47 and 2.20, respectively. Carcass traits from 5 commercial Hanwoo steer farm were then employed in the second analysis. Yield constants of each farm were estimated. In estimation, R² value for K1 (LABT) showed greater than the K2 (CWBT). Finally, each farm was plotted based on their K1 and K2 values and it was found that greater yield index of Hanwoo steer was found as increased K1 and K2. As conclusion, the present study suggested the possibility of K1 and K2 values for understanding of yield grade equation and their application in the evaluation of new model for yield grade estimation and feeding strategy.

In Tian mu bi lei cheng chu jie fa(田畝比類乘除捷法) of Yang Hui suan fa(楊輝算法)), Yang Hui annotated detailed comments on the method to find roots of quadratic equations given by Liu Yi in his Yi gu gen yuan(議古根源) which gave a great influence on Chosun Mathematics. In this paper, we show that 'Zeng cheng kai fang fa'(增乘開方法) evolved from a process of binomial expansions of $(y+{\alpha})^n$ which is independent from the synthetic divisions. We also show that extending the results given by Liu Yi-Yang Hui and those in Suan xue qi meng(算學啓蒙), Chosun mathematican Hong Jung Ha(洪正夏) elucidated perfectly the 'Zeng cheng kai fang fa' as the present synthetic divisions in his Gu il jib(九一集).

The goal of this study was to isolate and characterize the wild yeast strains from the gut of earthworm(Eisenia andrei). The 19 yeast strains isolated from 5 gut of earthworm samples from Nanji water regeneration center in Goyang-si, Gyeonggi-do, Korea. Among them, 16 strains were recorded and 3 strains, Yarrowia deformans YP242 (=KACC48778), Sporidiobolus pararoseus YP66 (=KCTC27963) and Naganishia liquefaciens YI9 (=KACC48948) were recorded for the first time in Korea. The microbiological characteristics of these previously unrecorded yeasts were investigated. All three strains were oval-shaped, convex and smooth. However, they showed some differences in colony color and result of carbon assimilation assays. YP242 was white-colored and assimilated glycerol, L-arabinose and N-acetyl-D-glucosamine as carbon sources. YP66 was red-colored and assimilated D-Saccharose. YI9 was whitecolored and positive for 2-keto-D-gluconate assimilation.

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.

The seismic design of conventional frame structures is meant to enhance plastic deformations at beam ends and prevent yielding in columns. To this end, columns are made stronger than beams. Yet yielding in columns cannot be avoided with the column-to-beam strength ratios (about 1.3) prescribed by seismic codes. Preventing plastic deformations in columns calls for ratios close to 4, which is not feasible for economic reasons. Furthermore, material properties and the rearrangement of geometric shapes inevitably make the distribution of damage among stories uneven. Damage in the i-th story can be characterized as the accumulated plastic strain energy (W_pi) normalized by the product of the story shear force (Q_yi) and drift (δ_yi) at yielding. Past studies showed that the distribution of the plastic strain energy dissipation demand, W_pi/ΣW_pj, can be evaluated from the deviation of Q_yi with respect to an "optimum value" that would make the ratio W_pi/(Q_yiδ_yi) -i.e. the damage- equal in all stories. This paper investigates how the soil type and ductility demand affect the optimum lateral strength distribution. New optimum lateral strength distributions are put forth and compared with others proposed in the literature.
