Behavior of Listeria monocytogenes in Skim milk during fermentation by Lactobacillus bulgaricus YI-2 and Streptococcus lactis FYI-1 were determined. Autoclaved skim milk was inoculated with ca. 10$^{3}$ L. monocytogenes (Strain LM91-1 or LM 96-2) cells/ml, and with 5.0, 1.0, 0.5 or 0.1% of a milk culture of either L. bulgaricus TI-2 or S. lactis FYI-1. Skim milk containing ca. 10$^{3}$ L. monocytogenes was incubated at 37 or 42$\circ $C for 15 h with L. bulgaricus YI-2, and at 21 or 30$\circ $C for 15 h with S. lactis FYI-1. Cultured skim milks were stored at 4$\circ $C in the refrigerater. Samples were plated on Oxford Agar with oxford antimicrobic supplement to enumerate L. monocytogenes and on either modified MRS agar to enumerate lactic acid bacteria. L. monocytogenes survived the 15-h fermentation with S. lactis FYI-1 in all combinations of level of inoculum and temperature of incubation, but inhibition of growth ranged from 94 to 100%. When incubated with over the 1.0% of L. bulgaricus, L. monocytogenes inhibited or disappeared in fermented skim milk from 9 h after incubation. Especially, incubation at 42$\circ $C with 5.0% L. bulgaricus YI-2 as inoculum appeared to be the most effective inhibitory combination for strain LM 91-1, causing 100% inhibition in growth based on maximum papulation attained. In most instances of incubated with L. bulgaricus YI-2, growth of the pathogene appeared to be completely inhibited when the pH dropped below 4.38.

It is of great significance to perform a ceremony with the utmost honor in every society and the fact is that ancient Koreans executed sacrificial rites to natural scenery with primitive reilgious things from the beginning of Korean history. Minute records on the various ceremonies to the Koryeo Dynasty are found in Koryeodogyeong and it might be said that there were no standing rules and the many ceremonies were resorted to an expedient, because in the Yi Dynasty the first codified ceremonial lawbook, Kukjooryeeui was formalized and after then all the ceremonies and formalities were carried out by the referential rules of the above-mentioned Kukjooryeeui. After the imperial enthronement of Kojong, all the ceremonial goods and flags symbolizing the heaven and auspicious animals-authority and fortune-were made by Daemyeongjibyei, which are found at Changdeokgung now. There are no remarkable differences in the Yi Dynasty between the records at the beginning and the remaines at the last stage, which shows once-fixed standing rules were kept faithfully to the end. The main patterns used on flags were of imaginary animals such as dragon, indicating the wish that countless authority and fortune should be realized. This is the former part of the study on the ceremonial flags in the Yi Dynasty and I hope the detailed idea and symbolic meaning concerning the flags will be discussed later.

In Chinese Mathematics, Jia Xian(要憲) introduced Zeng cheng kai fang fa(增乘開方法) to get approximations of solutions of Polynomial equations which is a generalization of square roots and cube roots in Jiu zhang suan shu. The synthetic divisions in Zeng cheng kai fang fa give ise to two concepts of Fan il(飜積) and Yi il(益積) which were extensively used in Chosun Dynasty Mathematics. We first study their history in China and Chosun Dynasty and then investigate the historical fact that Chosun mathematicians Nam Byung Gil(南秉吉) and Lee Sang Hyuk(李尙爀) obtained the sufficient conditions for Fan il and Yi il for quadratic equations and proved them in the middle of 19th century.

Improvements in various health indices have been ushered in, along with soaring economic growth in the last few decades in Korea. Life span of Koreans at present stands at somewhere around age of seventies. It seems of worth to elucidate some facets of health profile of historic Koreans during Yi dynasty encompassing about five hundreds years between the 14th and 19th century. Datas on health of historic Koreans are meager with exception for sovereigns for whom royal archives have been preserved intact through centuries. Though the health environments for monarchs are, no doubt, incomparable to that of the grassroot levels during the same period, health profile of monarchs would facilitate to assess health indices for historic Koreans during Yi dynasty. Arithmetic average of life span of 25 consecutive Kings(omitted the last two Kings under Japanese control) is 44.6 years of age 81 year old for King Yongjo and 16 year old for King Danjong, representing two extremes. The principal causes of death are septicemia, subsequent to infections of soft tissue and ether organs(8 in number, one-thirds of all). Secondly, both epidemic disease and vascular accidents caused deaths of three Kings each. Two kings succumbed to diabets and one suicide. The causes for the remainder, eight kings are hardly ciarified. The monarchs who contributed in establishment of new Yi dynasty with highspirited and disciplined survied beyond their fifties and sixties. In contrast, those who reigned during mid - era of the dynasty at its culmination succumbed to death in their young adulthood, most likely due to their indulgence in court life.

Objective : To observe the efficacy and safety of CheungYeolYiSeup-tang and Hwangbaek external dressings on dampness-heat pattern atopic dermatitis(AD) in a non-comparative study. Methods : 10 patients with AD were included for 4 weeks of treatment. Efficacy and safety assessment included the scoring atopic dermatitis index(SCORAD), typical signs and symptoms of AD, results of some laboratory tests related to toxicity, and the incidence of adverse events. Results : Improvements in efficacy parameters were observed and produced no significant changes in laboratory tests related to toxicity in these patients. Their SCORAD results significantly decreased after 4weeks(P value<.01, according to the Wilcoxon sum of ranks test). Similarly, significant reductions from baseline in subjective pruritus scores and (P value<.05 by the Wilcoxon sum of ranks test) and the mean average of individual signs and symptoms of AD were reported after 4 weeks(P value<.05, P<0.01 by the Wilcoxon sum of ranks test). There were no significant changes in eosinophil, neutrophil, lymphocyte, immunoglobulin E and ESR in blood serum by paired ttest. Conclusion :CheungYeolYiSeup-tang administration and Hwangbaek external dressings are an effective and safe treatment for the management of dampness-heat pattern atopic dermatitis.

This study is on the reproduction of King Sejong's costume presented in at the National Classical Music Institute in the late of 2008. The performance was presented focusing on the idea of ceremonial music of hoi-ryeyeon produced in the reign of king(1433). The reproduction of King Sejong's costume was undertaken to keep pace with the times and to pay due regard to the performance costume. The implications of the study are as follows. King Sejong's Hoi-ryeyeon ceremonial costume is a royal robe(gonryongpo), the best one of king's clothing. The basic type of gonryongpo is that of fastening four yongbos to danryoung. The type of gonryongpo is, therefore, made with reference to unearthed articles and portrait of the first king of the Yi dynasty. The yongbo is larger one than the late period of the Yi dynasty in the light of portrait of the first king of the Yi dynasty. The supporting type of gonryongpo is that of gonryongpo, dapho, and chulrik, king's dress granted by Myeong dynasty. In the late period jikryeong was used as supporting dress and fixed to be lining and included jikryeong. Therefore the order of supporting dress was jikryeong, dapho and chulrik and was reproduced with reference to unearthed articles in the early Yi dynasty, as did the small piece of crown, belt and shoes.

Basic summary of the medical administration: First of all, Liao Jin Yuan dynasties had broad cultural exchange between north and south that the two traditional medical administrations were closely linked which later formed a system that united as one. Establishment of governmental medical office and governmental medical education organization was the very first attempt in the history of the medical administration. The measure on promoting the social level of medical doctors has an important meaning on the growth of the medical field. Medical policy on prisoners was done under the new condition brought on from experience. Medicine not of China was broadly interchanged, medicine from Arab was spread throughout China, and the department on skeletal injuries and the dietary treatments had major development. At this era, under a overall expansion of politics, economy, culture and medicine, scholastic dispute on medicine triggered medical expansion.

This study focused on concretely how minority group's attitude accepting han-zu's culture changes. In the past, minority group's culture and han-zu's culture were acculturated spontaneously, not forcibly. But as the people's republic of china was founded and control of chinese government was intensified, control and interference of minority group area became aggressive, and acculturation became compulsory. However, after chinese economic reform, by economic affluence and modernization and urbanization according to economic affluence, acculturation of minority group's culture and han-zu's culture is changing from forced acculturation to spontaneous acculturation. Still there are some areas where mutual friction lasts because of forced acculturation. But except some areas the stream is changing rapidly to spontaneous acculturation. In the text, this study investigated process and present state of acculturation focused on hui-zu that implemented aggressive acceptance of han-zu's culture relatively early. Then this study investigated yi-zu society and cultural change focused on their spontaneous acculturation. In the modern society setting a high value on convenience and personal happiness rather than ideology and value, value of race becomes less attractive to young people of minority group who know modern civilization and convenience of city. In this respect, maybe hui-zu society is future of yi-zu society and minority group society.

This study is one of the preparatory tasks for this researcher to do Emotion Coding on AI. This time, we're doing an Emotion Coding for Sijo "Blue Mountain is My Meaning" by Hwang Jin-yi. Huang Jin-yi is doing Emotion Coding on Blue Mountain and Green Stream in this Sijo. These Emotions code, as seen in Emotion Codon, as in UUU. This phenomenon can be described in the form in which this researcher hypothesized. In other words, this Emotion Coding acts as a catalyst for the formation of an amino acid called phenylalanine. If we continue this research, it is thought that the function of literature, which is more healing, will be utilized in the future of mankind.
