Recently, a symptom similiar to black spot caused by Alternaria kikuchiana on the pear leaves is prevailing in Naju, Chonnam Province. This experiment was conducted in order to clarify causal agent and to survey present status on it. Disease lesions on the leaves were brown or black brown in color, circle or irregular circle in shape, $2\~6mm$ in diameter, and faintly zonal. Central part of lesions was gradually changed to greyish-white. The causal fungus was identified as Alternaria kikuchiana Tanaka causing black spot of pear reported previously on variety I-sib-se-gi (Nijisseki) of pear. However, this disease differed from that of typical black spot reported already in some aspects; It occurred more highly on matured leaves than on young ones. And it occurred severely in varieties Shin-heung, Shin-ko, Man-sam-gil(Okusankichi) etc. which have been reported as resistant varieties, while slightly in varieties Cho-ok(Hayadama), Park-da-cheung (Hakadahare) etc. which have been known as susceptible ones. From the results described above, it is considered that this disease is due to the differentiation in pathogenicity of Alternaria kikuchiana Tanaka in that area.

The importance of color is increasing in modern life and we call such present age that is color age. These day that all areas of life are being getting fashionize, ordinary people as well as design specialist are required of culture and knowledge about color. Color is important factor of marketing because ability that color appeals to human's sensitivity is bigger than form. Color design education is important curriculum at liberal arts course and in special design training course. Color expresses by hue, value and chroma but design spot is using mainly hue and tone color system. Therefore, it is very important that educate tone concept in color design education But research of hue and tone color system is insufficient in domestic. We educate foreign color system and use mainly imported color paper. When think influence that increase of color, we must develop hue and tone color system in suitable for color design education and plan the color paper that conform to it. This research designed usable "Hue and Tone Color System 253" for general color design education. Also I designed 121 color papers for primary grade, 181 color papers for intermediate grade, 253 color papers for higher grade of color design education as specific practical use of "Hue and Tone Color System 253".or System 253".

Isoflavone contents in soybean seeds are affected by both genetic and environmental factors. Correlation analysis between these factors and isoflavone contents are considered as valuable inputs when breeding improved soybean cultivars. In this study, the seeds of 49 soybean accessions grown in Korea were grouped as black, yellow, green, yellowish-green, pale yellow, and green with a black spot based on their seed coat colors. The contents of 12 isoflavones were analyzed and the association between isoflavone content and seed coat color was determined. The accessions were also grouped as early, intermediate, and late-maturing based on their days to maturity. Out of the 12 isoflavones, 11 were found in 2 accessions, 9 in 18 accessions, 8 in 11 accessions, 7 in another 11 accessions, and 6 in 7 accessions. The total isoflavone content (TIC) in black, yellow, green, yellowish-green, pale yellow, and green with black spot soybeans was in the ranges 2.110 ~ 5.777, 2.487 ~ 4.733, 2.185 ~ 4.413, 2.681 ~ 4.065, 1.827 ~ 4.085, and 3.376 ~ 4.133 mg/g, respectively. The average TIC was highest in green with black spot soybeans (3.616 mg/g), and lowest in pale yellow soybeans (2.875 mg/g). Besides, the average TIC was lowest in early maturing accessions compared to late- and intermediate-maturing accessions. TIC was strongly correlated to malonylgenistin (r = 0.91) and malonyldaidzin (r = 0.78) contents, and poorly correlated to glycitein (r = 0.04) and malonylglycitin (r = 0.18) contents. Also, days to maturity showed strong correlation with malonylgenistin (r = 0.47) content and TIC (r = 0.38). The principal component analysis outlined accessions with high TIC and diverse isoflavones along the first and second components, respectively. The results of the present study depicted that green soybeans with a black spot could be sources of high TIC. Furthermore, late-maturing accessions with diverse isoflavones in their seeds could be useful in future agricultural systems in Korea.

Choice and use of color are very important field for designer. Present color sprang by central field of design business unlike past. Color is used mainly by three fields of sensitivity, administration, mind. But, do substantial design including all of three fields at use. Practical research field that is based on basic research when see as actuality of domestic color design is been behind real condition. Specially, color sensitivity field and color management field are very important field, it can speak that color name arid related area are most important among two. Because collar name includes sensitivity and color management. This research constructs correct data because investigate and analyze and search all compatible color names that is announced in existing or is recorded in public cosmopolitanly. As a result, it is to promise accuracy when produce creation of idea and result of design using color name. Examined laying stress on color that domestic data that is used in research is basis with Korean industrial Standard, connection literature, on-the-spot probe. International data investigated American ISCC-NBS to base. Other abroad color name data examined official data of each country all systematically with Japan, Europe. Findings about 11,000 basis color names and 33,000 application color names sorted collection. Collection method and classification system follow in international standard and arranged for user's tile convenience. Also, use frequency did laying stress on Munsell that is high color system so that can aid in industrial design business. Improved to write all international standard color values sue as RGB, CMYK, XYZ and can be applied all in each field of design. Is applying and get along with continuation improvement and development in homepage of present KIDP, it may become more worth research.

Objectives The purpose of this study was to investigate the difference in color perception among Sasang Constitution in "The dress" which has been arousing controversy whether its color is blue/black or white/gold. Methods 85 participants classified as Sasang Constitution were asked to answer three questions about "The dress". They were asked firstly the overall colors of the dress, secondly the colors of the specific parts of it, thirdly color ranges they perceived as gold, white, blue, black, respectively. These process were run twice. Results and Conclusions The overall colors of the dress were perceived as blue/black more than white/gold, regardless of Sasang Constitution. And also the ratio between blue/black and white/gold were not significantly different among Sasang Constitution. But when a specific part(spot ii) shown, Soyangin perceived its color as blue more than Taeeumin in the first process. In the case of color range, Soyangin perceived range of black wider than Taeeumin in the second process.

Experiments of Cone calorimeter test and Lift spread flame apparatus test are carried out in order to appraise fire hazard in color nonwoven used mostly on the spot in construction works. As the result, in color nonwoven combustibility is discovered not firing flame in surface, but firing under state of combustible gas occuring in the state of melting. In the case of Lift spread flame apparatus test, color nonwoven is very brittle which almost no flame spread owing to contracting and break by firing strength. The following data are agree with basis: total heat release is 2.66 MJ/$m^2$, limited combustible material (10 min) of incombustible rating appraisal in interior material of building, and incombustible materials (5 min) 8 MJ/$m^2$ in spite of the above data mentioned, those data are only as basis of interior finish, and so I cannot judge color nonwoven have incombustible rating retain through the above data. Accordingly, the basis of incombustible rating and experiment method about exterior finish must be arranged also.

Anthracnose symptoms on Spiraea prunifolia were observed around the residential area of Dongbumyon, Geoje City, Gyeongnam Province, Korea in 2002 and 2003. Typical symptoms of the disease were dark red spot on the leaves and black spot on the stem. The pathogen formed gray to dark gray colony on potato dextrose agar. Conidia were single celled, color, ovoid or oblong in shape and $6{\sim}12\;{\times}\;3{\sim}5\;{\mu}m$ in size. Seta were dark brown in color, cone-shaped in shape and $23{\sim}42\;{\times}\;2{\sim}4\;{\mu}m$ in size. The optimum temperature for growth of the isolate was about $25{\sim}30^{\circ}C$. On the basis of mycological characteristics and pathogenicity test on host plants, the fungus was identified as Colletotrichum gloeosporioides. This is the first report on the anthracnose of S. prunifolia caused by C. gloeosporioides in Korea.

Over the past years, a large number of acrylate polymers have been developed and the overcoat thin layer containing acrylate polymers have been used for TFT-LCD color filter. As forming thin layer using acrylate polymers, the existing acrylate polymers have some problems such as low hardness by low Tg temperature, coating uniformity and solubility in organic solvent. To solve these problems, we synthesized new polymer(Scheme.), containing olefin monomer, which has high Tg temperature, good coating uniformity and good solubility in organic solvent. The overcoat thin layer containing new polymer resulted in good coating uniformity, stain, spot, scratch, heat resistance, DOP(Degree Of Planarization) on RGB glass, transparency, hardness, adhesion, anti-chemicals(anti-acid, anti-base, anti-organic solvent), insulation and anti-humidity. Scheme. The structure of new polymer X = Olefin monomer contains ketone, ester, hydroxy, ether, halogen, nitrile, alkoxy, phenyl functional group $R_1$ and $R_2$= H or $CH_3$. Ratio=0<[1/(1+m+n)]<0.7,0.1[$\leq$[n/(1+m+n)]<0.5.

Took an experiment of the jam manufacture with the raw material―the persimmons mellowed naturally and the persimmons which were got rid of astringency artificially―with many kinds of Korean persimmons. The results as follows : 1. Table 1. shows the analysis Table of the nutritional composition in the raw persimmon and Table 2. shows the gelation factor content in the persimmon. 2. Table 3. shows the mixture ratio of the manufacturing raw material of persimmon jam and shows the properties of the jam. 3. The color of the jam manufactured with made from the natural mellowed persimmons was persimmon color containing black spot or orange. But the jam manufactured with the persimmons which were got rid of astringency by ethanol changed from persimmon color to light purple during the storage. 4. The jam manufactured with the natural mellowed persimmons did not taste astringent but the jam manufactured with the persimmons which were got rid of astringency artificially tasted astringent.
