This study investigates the relationship of two architectures 'Kim Sa-haeng' and 'Park Ja-cheong.' They were the architects whose architecture were established and well known however they were not acknowledged by the people. Because they were not revealed under the large-scale national construction in complicated circumstances at home and abroad. The results were as follows; First, Kim Sa-haeng who was an overseas architect in Yuan dynasty stood out in all areas of architecture. Particularly in making royal tombs; His works were recognized as the most beautiful royal tombs ever existed and was later on followed by the Joseon dynasty. Second, Park completed the construction of Joseon's by faithfully reflecting on the discussed process of Neo-Confucian while coming after the time of the construction of Kim Sa-haeng. Third, although Kim Sa-haeng was a vassal of the Buddhist nation in Goryeo, he built the Moon-myo, a Confucian inspired temple of Joseon. Park Ja-cheong, who continued to build Kim Sa-haeng's architecture, reproduced Kim Sa-haeng's confucian's temple of Joseon dynasty while modifying it according to the situation in Joseon dynasty. The constructions of the two architects' monuments continues unabatedly. Their architecture has continued without massive changes.

By studying Hwang Jae Nae Kyung(黃帝內經)'s O Haeng Kui Ryoo(五行歸類) in view of Chinese-Ancient-Thought like Chun In Hap Il Lon(天人合一論). Um Yang O Hang Lon(陰陽五行論). The theory of the month's age the conclusion is reached as follows 1. Chun In Hap Il Lon(天人合一論) means naturally men and nature consist of one energy to counteract each other and then developed to be concidered that the change of men and nature is same one;that is the basic thought of Hwang Jae Nae Kyung(黃帝內經) 2. Um Yang(陰陽) stands originally for the bright and the dark by sunrise or sunset. Ju Yuk Gye Sa Jun(周易繫辭傳) ahs considered Um Yang(陰陽) as the energy to explain changes of nature. O Haeng(五行) meaned originally five necessary materials or stuffs for living and then Chu Yun(鄒衍) has considered the difference between five powers in the nature through the combination with thought of O Haeng(五行). Hwang Jae Nae Kyung(黃帝內經) writes in the viewpoint of Um Yang O Haeng(陰陽五行) to analyze the changes of men and nature effectively. 3. O Haeng Kui Ryoo(五行歸類) is originated from Sang Su Hong Bum(尙書洪範) and its concrete examples are found in Kwan Ja(管子) and Yu SSi Chun Chu(呂氏春秋). O Haeng Kui Ryoo(五行歸類) in Hwang Jae Nae Kyung(黃帝內經) is widly affected by Kwan Ja O Haeng(管子五行) and adopts the opinion of Kum Mun Kyung Hak(今文經學) because of the background of times and medical physiology. 4. Hwang Jae Nae Kyung(黃帝內經) thinks that O Haeng(五行) means Mok(木) is the energy of being born, Hwa(火) growing-up, Kum(金) accumulating, Su(水) concluding, To(土) devoloping. O Haeng Kui Ryoo(五行歸類) in the heaven and the earth is classified by the property of O Haeng(五行). 5. O Haeng Kui Ryoo(五行歸類) in men can be explained so rationally with the property of O Haeng(五行) and the thery of an organism studied.

Two major goals for chemical cleaning on the secondary side of nuclear steam generators are to remove sludge effectively and to minimize corrosion of base metals. In this work, electrochemical and sludge dissolution behaviors have been investigated in order to find out which parameters are critical and important during a copper removal process for chemical cleaning and to evaluate safety aspects and effectiveness of two major copper removal processes developed commercially in foreign countries. Hydrogen peroxide is vert effective for the process to use EDTA, NH$_4$OH and EDA at 38$^{\circ}C$ to control the potential of copper in a potential range sood for copper sludge removal. Corrosion rates for carbon steel SA 285 Gr.C and Alloy 600 are very small during this process if it is controlled properly. However, the corrosion rate of SA 285 Gr.C will be increased greatly if its corrosion potential is maintained below -450mV. The process to use EDA and ammonium carbonate is effective at 6$0^{\circ}C$ to dissolve copper sludge if the corrosion potential of copper can be controlled above -200mV. However, it is very difficult to raise the corrosion potential of copper to this range by air blowing and stirring.

Halophyte is a plant that has evolved to grow well in salty places, and is mainly distributed in coastal wetlands, sand dunes, salt fields, and reclaimed lands in tidal flats and river estuaries. Because it grows in the soil where seawater enters and exits, it is very abound in natural minerals and produces certain metabolites to survive sustainably in the surrounding environment. In this study, anti-inflammatory studies were conducted using 15 kinds of halophyte to secure data on halophytes of infinite value as functional materials. The aim of this study was to select a group of halophytes that regulate iNOS expression, which is involved in the secretion of inflammatory cytokines and nitric oxide production in LPS-induced macrophages. Among the 15 species of halophyte, except for Triglochin maritimum, Suaeda japonica, and Carex pumila, NO production was reduced in 12 species of halophytes, and 7 species of halophyte (Suaeda asparagoides, Artemisia fukudo, Spergularia marina, Aster tripolium, Suaeda australis, Atriplex subcordata, Calystegia soldanella) significantly decreased the expression levels of TNF-α and IL-1β.

I. Introduction The essence of Oriental medicine consists of ancient books, experienced doctors and succeeded skills of common society. Many famous doctors studied medical science by their fathers or teachers. So the history of medical science is long. $\ll$DangDaeMyeongIImJeungJeongHwa(當代名醫臨證精華)$\gg$ written by SaWoogWang(史宇廣) and DanSeoGeon(單書健) has many medical experience of famous doctors. So it has important historical value. Bi(痺) means blocking. BiJeung is one kind of symptoms making muscles, bones and jonts feel pain, numbness or edema. For example it can be gout or SLE etc. So I studied ${\ll}BiJeungJuJip{\gg}$. II. Final Decision Following decisions of Chinese doctors of 20th century are as follows ; 1. JuYangChun(朱良春) emphasized on IkSinJangDok(益腎壯督) to treat BiJeong. And he devided WanBi(頑痺) as PungHanSeup(風寒濕), DamEo(痰瘀), YeolDok(熱毒), SinHeo(腎虛). He used insects for medicine. 2. ChoSuDoek(焦樹德) introduced past prescription. He used ChiBiTang(治痺湯) to treat HaengBi(行痺), TongBi(痛痺), ChakBi(着痺). He insisted that Han(寒; coldness) and Seup(濕; dampness) be Eum(陰) and Pung(風; wind) can change his character to be Eum. After all BiJeung is usually EumJeung. So he used GaeJi(桂枝) and BuJa(附子). By the way he used ChungYeolSanBiTang(淸熱散痺湯) for YeolBi, BoSinGeoHanChiWangTang SaBok(王士福) emphasized on the importance of medicine. He introduced many treatments like CheongYeol(情熱) for YeolBi and YiO(二烏) for HanBi. And he divided BiJeung period for three steps. At 1st step, we must use GeoSa(祛邪), at 2nd step, we must use BuJeong(扶正) and at 3rd step, we must use BoHyeol(補血), he insisted. And he introduced many herbs to treat BiJeung. 4. JeongGwangJeok(丁光迪) said that GaeJi(桂枝), MaHwang(麻黃), OYak(烏蘖) and BuJa(附子) are very important for TongRak(通絡). And pain usually results from Han(寒), so he liked to use hot-character herbs. 5. MaGi(馬志) insisted that BiJeung usually result from ChilJeong(七情). And he liked to use insects for treatment of BiJeung. 6. WeolSeokMu(越錫武) introduced 8 kinds of treatments and divided BiJeung period. Also he divided BeJeung for PungBi(風痺), HanBi(寒痺) and SeupBi(濕痺). 7. SeoGeaHam(徐季含) observed many patients and concluded that 86.7% of BiJeung is HeuJeung(虛症). 8. YuJiMyeong(劉志明) said that YeolBi is important and CheongYeol is also important. So he emphasized on DangGyuiJeomTongTang(當歸拈痛湯) and SeonBiTang(宣痺湯). 9. WangLiChu(汪履秋) studied cause of WanBi. Internal cause is GiHyeolHeo(氣血虛) and GanSinHeo(肝腎虛) and external cause is SaGi(邪氣) he insisted. 10. WangSaSang(王士相) said that YeolBi can be SeupYeolBi or EumHeuYeolBi(陰虛熱痺) and HanSeupBi(寒濕痺) is rare. He use WooBangJaSan(牛蒡子散) and BangPungHwan(防風丸) for SeupYeolBi, DangGyuiSaYeokTang(當歸四逆湯) for HanSeupBi. 11. JinTaekGang(陳澤江) treated YeolBi with BaekHoGaGyeJiTang(自虎加桂枝湯) and SaMyoSan(四妙散). If they don't have effect, he tried to cure BiJeung step by step. And he used e term of GeunBi(筋痺) and BangGiMogwaEIInTang(防己木瓜薏苡仁湯) was good for GeunBi. 12. MaSeoJeong(麻瑞亭) said that PungSeupYeokJeul(風濕歷節) is BiJeung and it is related to GanBinSin(肝脾腎; liver, Spleen, Kindey). And he emphasized on balance WiGi(衛氣) and YoungHeul(營血). 13. SaJeJu(史濟桂) said that GeunGolBi(筋骨痺) is similar to arthritis and sometimes called ChakBi. And SinBi(腎痺) is terminal stage of ChakBi, he said. He also used insects for treatment. 14. JeongJeNam(丁濟南) tried to cure SLE and used GyeJi, CheonCho(川椒), SinGeunCho(伸筋草), SunRyeongBi(仙靈脾), HyconSam(玄蔘) and GamCho(甘草). 15. JinGYungHwa(陳景和) emphasized on diagnosis of tongue. If the color of tongue is blue, it usually has EoHyeol(瘀血), for example. And he also used insects. 16. JuSongI(朱松毅) tried to devide YeolBi with OnByeong(溫病), Wi(衛), Gi(氣) and Hyeol(血). 17. RuDaBong(蔞多峰) said that JyeongHeo(正虛), OiSa(外邪) and EoHyeol are closely related. And he explained BiJeung by deviding the body into the part, for example head, neck, shoulder, waist, upper limb and lower limb. 18. YuMuBo(劉茂甫) defined PungHanSyubBi as chronic stage and YeolBi as acute stage.

Glycyrrhizae Radix (GR), commomly known as liquorice, is a medicinal and edible plant widely used in East Asia with its pharmacological properties. Currently, Glycyrrhiza uralensis, G. glabra and G. inflata are used for pharmaceutical purposes in Korea and then the improved Glycyrrhiza varieties, WON-GAM (WG) has been developed by Korea Rural Development Administration. To evaluate equivalence of efficacy, several comparative studies between already-registered species and new cultivars have been conducted. To evaluate equivalence of efficacy, several comparative studies between already-registered species and new cultivars have been conducted. The aim of this study was to evaluate the effect of WG on fecal microbiota in DSS-induced colitis model. Fecal microbiota was analyzed by terminal restriction fragment length polymorphism (T-RFLP). The composition of the fecal microbiota did not show a specific pattern based on experimental groups; however, a tendency toward an increase in the proportion of Lactobacillales was observed. Glycyrrhiza varieties could change composition of fecal microbiota in DSS-induced colitis model. This work was carried out with the support of "Cooperative Research Program for Agriculture Science and Technology Development (Project No. PJ014246022020)" Rural Development Administration.

The genus Glycyrrhiza (Licorice) has been used as an oriental herbal medicine for a long time in Asian countries. Wongam (WG), which is Glycyrrhiza new variety, have been developed to improve limitation of licorice including low productivity, environmental restriction and insufficient components by Korea Rural Development Administration. To using WG as a herbal medicine, it is important to reveal the adverse effects in health. In this study, we evaluated the genotoxicity test of WG extract through in vitro bacterial reverse mutation (AMES) assay, in vitro chromosomal aberration assay and in vivo mouse bone marrow micronucleus assay. When compared with the control, WG extract with or without the S9 mix showed no genotoxicity in the AMES assay up to 5000 ㎍/plate and in the chromosomal aberration assay up to 1100 ㎍/ml. In micronucleus assay, no significant increase in the number of micronucleated polychromatic erythrocytes or in the mean ratio of polychromatic to total erythrocytes up to 5000 mg/kg/day for 2 days. The present study demonstrated that WG extract is safe and reliable herbal medicine since no detectable genotoxic effects at least under the conditions of this study.
