In order to setup the diet guideline of five grains, five meats, five fruits, and five vegetables for the diseases of five organs, I reviewed the their tastes by comparing "Naekyeong" with "Euhakibmun", "Dongeuibogam". 'Ma(麻)' in "Naekyeong" means not a hemp, a ramie or a jute, but a sesame(胡麻;참깨). 'Maik(麥)' in it means both a barley(大麥;보리) and a wheat(小麥;밀). 'Guak(藿)' in it means bean leaves(콩잎), leaves of a red-bean(팥잎) or brown seaweed(海藻;미역). 'Gyu(葵)' in "Euhakibmun Jangbujobun(臟腑條分)" is a miswritten word for 'Welsh onion' caused by similarity of shape of word. Food of a salty taste according to five elemental arrangement in "Naekyeong" is really salty according to "Euhakibmun" and "Dongeuibogam". But a barley(大麥) and a wheat(小麥) of sour taste are bitter, a chicken of sour taste or hot taste is sweet, nonglutinous millet of sour taste is sweet, an apricot of bitter taste is hot, a sesame seed of sweet taste is sour, a nonglutinous rice of hot taste is sweet, and a horsemeat of hot taste is bitter according to them. There are two ways to recommend the food for diseases of five organs. One way is to promote or control the Qi(氣) of five organs according to "Somun(素問)" and "Euhakibmun Jangbujobun", the other way is to build up the Yin(陰血) of five organs according to "Yungchu(靈樞) five tastes(五味)". The two different ways are not contradictory to each other, but complement on the view point of their substances(體) or actions(用).

The new spectrometer for X-ray Induced Electron Emission Spectroscopy (XIEES) .has been recently developed in KRISS in collaboration with PTI (Russia). The spectrometer allows to perform research using the XAFS, SXAFS, XANES techniques (D.C.Koningsberger and R.Prins, 1988) as well as the number of techniques from XIEES field(L.A.Bakaleinikov et all, 1992). The experiments may be carried out with registration of transmitted through the sample x-rays (to investigate bulk samples) or/and total electron yield (TEY) from the sample surface that gives the high (down to several atomic mono-layers in soft x-ray region) near surface sensitivity. The combination of these methods together give the possibility to obtain a quantitative information on elemental composition, chemical state, atomic structure for powder samples and solids, including non-crystalline materials (the long range order is not required). The optical design of spectrometer is made according to Johannesson true focusing schematics and presented on the Fig.1. Five stepping motors are used to maintain the focusing condition during the photon energy scan (crystal angle, crystal position along rail, sample goniometer rail angle, sample goniometer position along rail and sample goniometer angle relatively of rail). All movements can be done independently and simultaneously that speeds up the setting of photon energy and allows the using of crystals with different Rowland radil. At present six curved crystals with different d-values and one flat synthetic multilayer are installed on revolver-type monochromator. This arrangement allows the wide range of x-rays from 100 eV up to 25 keV to be obtained. Another 4 stepping motors set exit slit width, sample angle, channeltron position and x-ray detector position. The differential pumping allows to unite vacuum chambers of spectrometer and x-ray generator avoiding the absorption of soft x-rays on Be foil of a window and in atmosphere. Another feature of vacuum system is separation of walls of vacuum chamber (which are deformed by the atmospheric pressure) from optical elements of spectrometer. This warrantees that the optical elements are precisely positioned. The detecting system of the spectrometer consists of two proportional counters, one scintillating detector and one channeltron detector. First proportional counter can be used as I/sub 0/-detector in transmission mode or by measuring the fluorescence from exit slit edge. The last installation can be used to measure the reference data (that is necessary in XANES measurements), in this case the reference sample is installed on slit knife edge. The second proportional counter measures the intensity of x-rays transmitted through the sample. The scintillating detector is used in the same way but on the air for the hard x-rays and for alignment purposes. Total electron yield from the sample is measured by channeltron. The spectrometer is fully controlled by special software that gives the high flexibility and reliability in carrying out of the experiments. Fig.2 and fig.3 present the typical XAFS spectra measured with spectrometer.

현재 통일신라 범종은 한국에 6점, 일본에 5점, 기타 2점 등 총 13점이 알려져 있으며, 이중 3점은 형태추정이 불가능하다. 따라서 형태추정이 가능한 10점을 이용하여 범종의 형식을 구분하고, 이중 운천동 종의 조사 자료를 토대로 기존에 과학적 조사가 이루어진 통일신라 청동범종과의 연계성을 찾아보고 조성비를 중심으로 한 제작기술의 접근을 시도해 보았다. 통일신라 범종의 도상분석은 2가지 형식으로 나누었는데, I형식은 좌우대칭 비천과 정형성의 문양 배치구조를 갖는 전기종의 모습이며, II형식은 좌우비대칭 비천과 비정형성의 문양 배치구조를 띄는 후기종의 모습이다. 특히 운천동(雲泉洞) 종은 9세기 고묘지(光明寺) 종과 매우 흡사한 문양형태를 보이는 후기 종으로, 통일신라주악비천에서 전혀 보이지 않았던 종적(縱笛)을 연주하고 있는 것이 특이할 만하다. 통일신라 범종은 대부분 합금배합구성이 Cu-Sn, Cu-Sn-Ph으로 이루어져 있으며, 8세기와 9세기에 걸쳐 구리, 주석, 납을 골고루 사용하여 주종(鑄鐘)하였고, 고대 중국 "주례(周禮)" "고공기(考工記)"의 청동합금비와 근접하게 나타났다. 특히 운천동 종은 Cu-Sn-Ph-As 구성을 이루고 있으며 통일신라 범종에서 자주 사용되지 않은 As가 검출되어 이에 대한 관련 자료를 제시하였다. As는 Pb사용 성격과 유사하나 재질의 특성상 고온에서 쉽게 휘발되기 때문에 사용상에 어려움이 있으나, 제품을 단단하게 하여 오래 사용할 수 있는 장점이 있다. Ph는 주물의 유동성을 좋게 하여 문양을 잘 표현하게 하고, As는 제품의 강도를 높여줄 수 있다. 납동위원소비 분석결과 구체적 산지추정은 어려웠으나 시료의 분석 결과를 통하여 종 제작에 있어 한 광상의 재료를 사용했다는 근거를 제시할 수 있었다.
