This work aims to suggest the most proper Hwangtoh color(ocher) for sidewalks and walkways located at the central part of the city. The actual colors of Hwangtoh samples that were obtained from 3 different locations (mountain walkways) in Busan were measured. In addition, personal preferences of such Hwangtoh colors were evaluated through survey in order to provide a proper standard reference color for urban walkways and sidewalks. With respect to the chromaticity of Hwangtoh obtained in Busan, $a^*$ and $b^*$ values were found to range from 3.6 to 13.6 and 11.4 to 23.4, respectively. It was also found that $L^*$ (lightness) values of 3 different Hwangtoh samples were found to be similar. According to the results from survey, higher values of $+a^*$ (red type) and $+b^*$ (yellow type) were preferred, indicating the red and yellow color needs to be developed stronger from Hwangtoh. Based on these findings, the proper Hwangtoh color used for walkways in urban area was chosen. It was found to be $L^*$ for 32.2~45.8, $a^*$ for 5.2~13.6, and $b^*$ for 15.8~21.2, respectively.

This study aims to characterize the sensibility image and interaction effect of striped necktie according to same-tone coordination and 1:2:3 area-ratio variation on the gender. The experimental materials developed for this study are a set of stimuli and response scales. The stimuli consist of 56 color pictures manipulated with every combination of 4 different colors, 2 different tones and 7 different area-ratio. The 7-point scale designed for visual evaluation of sensibility image included 26 bipolar adjectives. The subjects were 1344 undergraduate students in Gyeongnam, Seoul, Busan, and Daegu areas. The results of this study were as follows. The analyses of sensibility images in terms of same-tone coordination and 1:2:3 area-ratio variation of stripe necktie reveal that the concerned factors are of five characteristic dimensions of attractiveness, youth-activity, appeal, ability, and warmness. In the 5 factors of sensibility image, color combination and tone showed independent effect. In addition, significant interaction effects of area-ratio and tone on appeal and ability were found. Interaction effects of gender and area-ratio on youth-activity were found. Interaction effects of gender and tone on warmness were found. Interaction effects of color combination and tone on appeal and warmness were found. The study results are highly expected to be used as useful sources in developing men's coordination.

The purpose of this study is to formulate a concept of naturalism in fashion and verify the design characteristics found in such designs via reviewing the concept of naturalism and its influence on dress making in different periods in history. The references from various academic fields including philosophy, literature and fine arts were used to examine how the naturalism was formulated over the years. This study was then to identify the naturalistic influences by closely examining various Western dress codes found in literature, publications and actual samples. The results of this study shows that the close examination of naturalism in fashion with the changes of times displayed the complex evolution process over the years, and they were classified by four distinctive categories; Retro, Ecology, Primitive and Ethnic. Naturalism in the contemporary fashion design showed higher frequency of adopting ecological and retro styles, especially retro style adoption being on the rise, combining wide range of partial components of each style. The color usage showed the skewed concentration on YellowRed, Red and Yellow colors with pale, light grayish and grayish tones.

Content analysis of food advertisements was undertaken to investigate the nature of the messages related to health, nutrition or consumer-promotion in 2001 women's magazines. Advertisements on baby foods were collected from three women's magazines and the final samples obtained were 42 different copies of advertisements. All the messages in each sample were counted and calculated for their frequency (％). Messages were categorized into four areas (health, nutrition, non-nutrition, consumer promotion), and each area was classified into more detailed categories. Results showed that all the messages in 42 samples and average messages per advertisement were 1288 and 30.7, respectively. The most common type of promotional messages was health related (e.g., appeal to enhanced immune function and disease prevention and brain development), followed by consumer related, nutrition and non-nutrition messages in order. Messages about high quality and all natural ingredients were more emphasized in the consumer related category. Messages on fats (DHA, lecithin and arachidonic acid), proteins (neucleotides, taurine) and mineral (calcium, iron) were most frequently found in nutrition category. Amongst the three kinds of baby foods, formula ads had the most numerous messages related to health and nutrition. There were more consumer related messages in the ads of weaning foods, and more promotional messages about no addition of antiseptic, artificial additives, and food colors in the ads for older infant foods. Messages violating regulation (e.g., exaggerated or inaccurate or non-scientific messages) were frequently found in the advertisements of three kinds of baby foods. In conclusion, tighter supervision of food advertisements and nutrition education is required to protect the consumers from misleading advertisements.

Among semi-quantitative or fully quantitative lateral flow assay readers, an image sensor-based instrument has been widely used because of its simple setup, cheap sensor price, and compact equipment size. For all previous approaches, monochrome CCD or CMOS cameras were used for lateral flow assay imaging in which the overall intensities of all colors were taken into consideration to estimate the analyte content, although the analyte related color information is only limited to a narrow wavelength range. In the present work, we introduced a color CCD camera as a sensor and a color decomposition method to improve the sensitivity of the quantitative biosensor system which utilizes the lateral flow assay successfully. The proposed setup and image processing method were applied to achieve the quantification of imitatively dispensed particles on the surface of a porous membrane first, and the measurement result was then compared with that using a monochrome CCD. The compensation method was proposed in different illumination conditions. Eventually, the color decomposition method was introduced to the commercially available lateral flow immunochromatographic assay for the diagnosis of myocardial infarction. The measurement sensitivity utilizing the color image sensor is significantly improved since the slopes of the linear curve fit are enhanced from 0.0026 to 0.0040 and from 0.0802 to 0.1141 for myoglobin and creatine kinase (CK)-MB detection, respectively.

Silage comkv, suwwn 19). sorghum $\times$ sudangrass(p. 988) and winter ryeNaton) were cultivated on imperfectly drained paddy field under two different draining methods, subsurface darinage by PVC pipes and open ditsched surface drainage. The crops were harvested at the stage of hard dough for corn and soft dough for wrghum and rye. The soil physical properties. soil colors. soil structure and soil wetness were improved in the subsurface drainage. Gravitational water table occured depth in 110 cm(dry season)~75cm(rain season). In soil profile description, yellowish brown with yellowish red mottles and well developed granular structure were found in the surface A horizon. The portion of solid phase in subsoils(B horizon) was reduced from 48.6%(undrained) to 43.7 %. A blocky structure with dark gray to gray were described in the open ditsched surface drainage. Severe wet depression of the crops was observed due to it's higher moisture contents, where the gravitational water occured depth in 25~37cm during the rainy season. The chemical properties of paddy soils were less affected by drainage methods. The concentration of available phosphate. organic matter and exchangeable K, Ca and Mg were decreased in the subsurface drained soils. The annual dry matter yields of com-rye cropping were 17.8 ton in the undrained, 21.6 ton in the open ditsch drainage and 35.9 ton/ha in the subsurface drainage.

Yellow poplar is well known commercial hardwood species in the world because of its availability, rapid growth, large size, excellent form, early natural pruning, and the good working quality of the wood. Therefore, yellow poplar (Liriodendron tulipifera L.) has been adopted in South Korea for decades ago, and its cultivating the saplings and silvicultural system have been studied. However, yellow poplar is still embroiled in controversy for utilization of use and worth. This species has not only advantages such as lower weight, light color, and higher machinability and bending processing, but also has disadvantages which are bad smell and different colors on heartwood and sapwood. In this study, the objective was that use of yellow poplar board as furniture materials by drying and painting process. Thirty years old yellow poplar was cut and dried for 7 days by high-frequency dryness. Adjustment of color tone to walnut color was conducted with multiple colorants and various number of spread times. Uniform color of yellow poplar on heartwood and sapwood was accomplished by applying 1 time stain (green), 2 times transparent primer, 1 time middle-painting (walnut), and 2 times top-painting (walnut) in sequentially. The painted yellow poplar board was used to manufacture table and dressing table. During the furniture manufacture process, no critical issues were occurred on part of jointing and painting. This painting method may be useful data for future use of yellow poplar as furniture materials.

Colorant concentrates are prepared by use of concentration method of colorants extracted from Sappan wood using met hanol. Dyeabilities and fastness properties of silk fabrics dyed with concentrate of Sappan wood are investigated.The results obtained are as follows; 1. The storage stability of colorant concentrate is poor as concentration is excess. 2. Because the colors of dyeings are different with mordants, aluminium acetate, copper acetate, chromium alum and tin chloride are used in order to obtain reddish color. 3. The optimum dyeing temperature and dyeing time are 6$0^{\circ}C$ and 60 min, respectively. 4. Dry cleaning fastness is very good, and light fastness and washing fastness are low. 5. The dyeing method is simple owing to usehess of colorant concentrate prepared without extraction of colorant every time.
