Potatoes have been recognized for a long time as one of the major food crops as well as horticultural crops. Potato production as a table food has been decreased in developed countries, while it has been steadily increased in the third world countries for it importance as food source. It is a new trend to look for the food, not only as a feeding crop but also healthy food. It is also time for the potato producers to look for the potato having high economic value as found in medicinal plants. There are great diversities in potato species, indicating that valuable compounds can be found in different amounts, depending on potato species. We screened the cultivars, breeding clones, and germplasms based on the vitamin C, Vitamin E, antioxidant compounds, diverse sugar types, important amino acids, and other valuable compounds. We could select the breeding clones KC003, 98Wl17, 99j717, and Vally 8 (A group) due to their high levels of antioxidant compounds, and it can be said that most of the red and purple colored potato clones belong to the A group. In the contents of essential amino acids, ‘Taebook Valley’,‘Summer Valley’ and other breeding clones were found to be high in amount. We also made crosses between breeding clones with high biological function and low agronomic traits and low biological function with high quality in agronomic characteristics . The patterns of genetic trends of these offsprings in comparison with their parents will be reported as well. And the potential of using potato as antibody production of anti-cancer will be discussed.

Objectives: The objective of this study was to develop a zinc database (DB) to estimate the intake levels of zinc in Korean toddlers and preschool children using the data from the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 3,361 food items for the DB representing the usual diet of Korean toddlers and preschool children were selected based on KNHANES (2009~2013) and the food composition table of Rural Development Administration (RDA). The existing values of zinc in foods were collected from the latest food composition tables of RDA (9th revision) and the US Department of Agriculture (legacy release). The zinc contents were filled preferentially with these collected values. The missing values were replaced with the calculated values or imputed values using the existing values of similar food items from the data source. The zinc intake levels of Korean toddlers and preschool children were estimated using KNHANES and zinc DB Results: A total of 1,188 existing values, 412 calculated values, and 1,727 imputed values were included in the zinc DB. The mean intake levels of zinc for 1-2-year-old children and 3-5-year-olds were 5.17 ± 2.94 mg/day and 6.30 ± 2.84 mg/day, respectively. There was no significant difference in the zinc intake levels between boys and girls in each group. Conclusions: This newly developed zinc DB would be helpful to assess the zinc nutritional status and investigate the association between the zinc intakes and related health concerns in Korean toddlers and preschool children.

Objectives : The purpose of this paper is to describe how Wu Kun(吳昆) understood Huangdineijing 『黃帝內經』 and implemented his understanding when writting Yifangkao 『醫方考』. Methods : From Yifangkao 『醫方考』, we collected all paragraphs including "經曰", "內經曰" while excluding the ones with "論曰" to filter out Sanghanlun 『傷寒論』's perspective. The contents of Huangdineijing·Suwen 『黃帝內經·素問』 and Huangdineijing·Lingshu 『黃帝內經·靈樞』, cited in Wu Kun's Yifangkao 『醫方考』 were extracted, identified from which part it comes and sorted into headings under RyuPyeon Huangjenaegyung 『類編黃帝內經』. Results : The most cited traditional chinese medical classic in Yifangkao 『醫方考』 was Huangdineijing·Suwen 『黃帝內經·素問』 Yinyangyingxiangdalun 「陰陽應象大論篇」 which was cited 41 times. Zhizhenyaodalun 「至眞要大論篇」 had a total of 39 citations followed by Shengqitongtianlun 「生氣通天論篇」 and Liuyuanzhengjidalun 「六元正紀大論篇」 which were cited 13 times and 11 times each. In addition, it was confirmed that other 28 chapters from Huangdineijing·Suwen 『黃帝內經· 素問』, 3 chapters from Huangdineijing·Lingshu 『黃帝內經·靈樞』, 3 chapters from Nanjing 『難經』 and one chapter from Zhenjiujiayijing 『鍼灸甲乙經』 were also cited. Also the analysis of the classification of the Huangdineijing·Suwen 『黃帝內 經·素問』 showed that 57 citations were classified as 'treatment', 41 citations were classified as 'Yin and Yang and Five phases', 39 citations were calssified as 'Cause and Mechanism of Disease'. Conclusion : 1. Yifangkao 『醫方考』 have explained prescriptions by implementing principles from 5 kinds of traditional chinese medical classic including Huangdineijing·Suwen 『黃帝內經·素問』, Huangdineijing·Lingshu 『黃帝內經·靈樞』 etc. 2. According to table 3, Yifangkao 『醫方考』 have cited Huangdineijing·Suwen 『』 to explain how each compounds were used and how the Korean medical principle of Yin and Yang was applied in the prescriptions. 3. It can be suggested in formula study there is utility to understand principles of traditional chinese medical classic to comprehend prescriptions.

The purpose of this study is to generate the local level knowledge structure of a single document, similar to end-of-the-book indexes and table of contents of printed material through the use of term clustering and cluster representative term selection. Furthermore, it aims to analyze the functionalities of the knowledge structure. and to confirm the applicability of these methods in user-friend1y information services. The results of the term clustering experiment showed that the performance of the Ward's method was superior to that of the fuzzy K -means clustering method. In the cluster representative term selection experiment, using the highest passage frequency term as the representative yielded the best performance. Finally, the result of user task-based functionality tests illustrate that the automatically generated knowledge structure in this study functions similarly to the local level knowledge structure presented In printed material.

A combination of two specifically different pigments, phycoerythrine and chlorophyll, gives the laver shining black color. This shining black color is the dominant factor in deciding tile quality of the dried product of laver (dried laver). Therefore, this experiment was carried out to know the effect of tannic acid as a pigment fixing agent. Raw laver, Porphyra spp., was treated with tannic acid solutions to prevent dissolution of biliproteins especially phycoerythrine in to the fresh water. This danger is mostly revealed when the chopped and shredded lavers are suspended in fresh water before the laver sheets are finally made. The influence of mechanical damage with different diameters of chopper plate on dissolution of the pigment was also mentioned. Theresultsobtainedareasfollows: 1. When the raw laver not yet chopped was stored for 3 days at $1\~5^{\circ}C$ in a dark place, the contents of chlorophyll and phycoerythrine decreased. 2. In the organoleptic test (Table 2,3,4),: the dried laver with a good coloration and surface gloss was obtained from a chopper plate with 7 mm or 3 mm. 3. A tannic acid solution of $0.02\%$ and $0.004\%$ appeared effective In preventing dissolution of phycoerythrine.

The headache has various causes and symptoms in clinic. Therefore The headache and the stiff neck also can found in many articles of Shanghanlun(傷寒論) On Cold Damage. In the past, many doctors classified the headache and the stiff neck according to their own theories, and published some Shanghan books(傷寒書). In this study, I select ten Shanghan books which classified the headache and the stiff neck in table of contents, and compared with the articles of and , the first books of Shanghanlun(傷寒論) to found meanings of them. As a result, the Osuyutang(吳茱萸湯) was the most quoted herb medicine of . The second was Jowisunggitang(調胃承氣湯) and Sosunggitang(小承氣湯), the group of Sunggitang(承氣湯類). Mahwangtang(麻黃湯) and Gyejitang(桂枝湯) are substituted as Ganghwalchunghwatang(羌活沖和湯) in for simply prescribe medicine, or even not mentioned as in . This can be understand as a result of copy the previous generation doctor's writings, not as a study of and . The articles of the headache in was not quoted in that ten books. But the stiff neck was frequently quoted that Gyejigualutang(桂枝加括蔞湯), Dehamhyungtanghwan(大陷胸湯丸) articles includes chibyong(痓病) The Opisthotonos, gyongbyong(痙病) The Convulsions, Yuchi(柔痓) Opisthotonos With Sweat And Fever.

XML has already been settled down as a standard for the exchange of commercial data on the web. Though most institutions have a wish to use XML document as an EDI form for all sorts of document exchange, it is unfortune that previous commercial data is still saved in the relational form of data base. Therefore, it is necessary that data saved in the relational form of data base be transformed into XML document form for the better use of document exchange. In order to transform relational form of data base to XML, one solution is to publish XML document by way of mapping each field of the relational form of data base table onto XML. However, in the case of building one XML document out of more i~km two data base tables, a join should be performed since a mere mapping associated with DTD tan not solve the problem. In this paper, we build the view for the XML in which alignments generated from the join are presented. and then through this view the contents with the relational form of data base should be transformed into XML. Briefly speaking, This paper aims to propose algorithm concerned with this transformation and to realize it.

The Daeheung Dolomite Mine, which is about 6km south of Danyang, Chungcheongbugdo, is coincided with almost central portion of the Danyang quardrangle scaled in 1 : 50,000. The purpose of this report is to prepare a information for the economic evaluation on the mine. Geology of the region is composed of worm-eaten limestone, crystalline limestone, crystalline dolomite rock, sandstone and shale from bottom, those are applicable to socalled Dumugol and Maggol formation of Ordovician, and batholithic biotite granite is intruded the west-side of the ditto sedimentary rocks. The dolomite bed, emplaced in bottom of the upper limestone formation, so-called Maggol formation, is about 270m in thickness, and dips $30^{\circ}{\sim}50^{\circ}$ northwest. The facies of the dolomite rock contained many brucite crystals is not only coarse-grained crystalline, but also micro crystalline in contact metasomatic parts. 25 samples were taken from the two series, A and B, in the nearly crossed direction to the strike of the dolomite bed as shown in the geological map. They were chemically analysed on the components of MgO, CaO, and $SiO_2$ as shown in Table 2. The estimate ore reserves total some 107,200,000 metric tons above the 320m level with the following average contents: MgO 21.80%, CaO 29.27% and $SiO_2$ 0.64%. It is caused by brucite minerals that MaO content in the dolomite rock is higher than pure dolomite (21.7%). The dolomite ore is possible in use for magnesian fertilizer, magnesian cement and refractory material, especially the microcrystalline dolomite ore is useful for a refractory material in furnaces of iron industries.
