Recently, many people can experience the virtual space by smartphone, and they use many games. In particular, this change has great implications in the collaborative and communicative planning paradigm, which is residents' participation and agreement becoming important in community making and urban design. This study analyze the case of the five virtual space games about community making and urban design, and examine the related regal system. Game users can construct roads, houses, buildings and facilities in the virtual city. Then, they create profit, and promote the growth of virtual city. In these games, construction elements are classified residential, commercial, industrial, parks, green spaces, public building, and roads. But these elements does not identified clearly, and they mixed. By analyzing of related regal system, these games focus on the individual buildings, spaces, and facilities rather than considering the terms of urban planning. To complement the virtual space game with the aspects of urban planning, these games can encourage the participation capability and enhance the communication skills of citizens.

The merging of different scales or multi-sensor image data is becoming a widely used procedure of the complementary nature of various data sets. Ideally, the merging method should not distort the characteristics of the high-spatial and high-spectral resolution data used. To present an effective merging method for survey of reclaimed land using the high-resolution (6.6 m) Electro-Optical Camera (EOC) panchromatic image of the first Korea Multi-Purpose Satellite 1 (KOMPSA T-l) and the multispectral Moderate Resolution Imaging Spectroradiometer (MODIS) image data, this paper compares the results of Intensity Hue Saturation (IHS) and Principal Component Analysis (PCA) methods. The comparison is made by statistical and visual evaluation of three-color combination images of IHS and PCA results based on spatial and spectral characteristics. The use of MODIS bands 1, 2, and 3 with a contrast stretched EOC panchromatic image as a substitute for intensity was found to be particularly effective in this study.

The color is one of the important key words in Fashion arena today. In fashion, the image and concept changes by use of color or color combinations. The purpose of this research is to pursue the characteristics of color and color combinations through analyzing the colors utilized in oriental fashion design. It is necessary to define the oriental fashion design to build a criteria for collecting law materials for analysis of the research. As a conclusion, traditional oriental colors already used in various traditional artifacts were popular in use by many fashion designers with volatile attitudes towards its original symbolic meanings or philosophy. For example, yellow and red stands for gorgeous or sexy images through fashion design instead of express its original symbols of power and prosperity. The Complimentary Color Combination in hue, value and intensity of colors were also found in fashion design impling oriental images. While Contemporary Fashion Trend Color were also used in expressing Oriental images with oriental details considering fashion market. In using Oriental colors The characteristics of oriental colors and its combinations used in fashion designs are significant and their influences are meaningful not only in fashion design but also adjacent design areas.

Niveteen stimulus photographs varied in hue and color scheme of one clothing style of Korean dress worn by a female were used to explore the differences in perceptive effect of clothing cues(color, color scheme, structure) on impression formation and graduate students. The data were analyzed by factor analysis, factor score, ANOVA and Scheffe-test. Results indicate perceptive effects of clothing cues on impression formation are influenced by gender-differences and major-difference of perceivers. Significant gender differences were found in perception of clothing cues on impression effect. Interaction effects were found between clothing cues and gender. Significant major differences were found in perception of clothing cues on impression effect. Interaction effects were found between clothing cues and perceiver's major. Female perceivers and perceivers of major-ing in Liberal Arts reacted to clothing cues on impression formation with greater sensitivity than male perceivers and perceivers of majoring in Natural Sciences. Frequent interaction effects between gender and color of China (cool-warm color), between major difference and color scheme(related color harmony-contrasting color harmony) appeared on factors of impression effect. The influence of perceiver variables on their perception of clothing cues for impression effcet has important implications for gender difference and perceiver's maforing backgroung in a social situation.

This paper presents the results of the study of vertically natural frequency of tractor tires are effected by changing different ground contacts and inflation pressures using the Free Decay Method. The results show that the natural frequencies of the tire are not affected while the vertical acceleration increased strongly due to the increase of inflation pressure when the tire performs free decay vibration on rigid ground. In addition, the number of natural frequency peaks of the tire also increases with increasing tire inflation pressure. On the other hand, the natural frequencies of the tractor tire increases strongly while the vertical acceleration decreases slightly with the increase of tire inflation pressure as the tire performs free decay vibration on soft soil. Further, the natural frequencies of tire-soil system are always higher than that of tire only, and it changed with changing the soil depth. Results also show the natural frequency of tire and tire-soil system is in the range of 3.0 to 10.0 Hz that lie within the most critical natural frequency range of the human body. These findings have to be mentioned and used as design parameters of the tractor suspension system.

The purpose of this research was to investigate the effects of clothing style and color of male casual wear on image perceptions and age evaluations. $4{\times}2$ (top color${\times}$trouser color) and $2{\times}3{\times}2$ (clothing style${\times}$clothing hue${\times}$clothing chroma) factorial designs were used as the experiment designs. Photoshop program was used to manipulate the clothing colors after creating photos of models wearing experiment clothing for stimulus. Subjects were 280 female college students from Seoul region and each subject responded to two stimuli. Factor analysis showed four factors of images of male casual wear; sociability, conspicuousness, softness and masculinity. Polo shirts were evaluated higher in sociability and softness than jumpers and nary blue trousers were evaluated higher in masculinity than beige trousers. High chroma clothing was assessed higher in sociability and conspicuousness than low chroma clothing. High chroma red jumpers displayed very sociable feel and low chroma blue jumpers displayed the lowest sociability. High chroma male clothing resulted in younger age perception but age was evaluated young when a black shirt was worn under the jacket when wearing a low chroma jacket.

The merging of different scales or multi-sensor image data is becoming a widely used procedure of the complementary nature of various data sets. Ideally, the merging method should not distort the characteristics of the high-spatial and high-spectral resolution data used. To present an effective merging method for survey of reclaimed land, this paper compares the results of Intensity Hue Saturation (IHS), Principal Component Analysis (PCA), Color Normalized(CN) and High Pass Filter(HPF) methods used to merge the information contents of the high-resolution (6.6 m) Electro-Optical Camera (EOC) panchromatic image of the first Korea Multi-Purpose Satellite 1 (KOMPSAT-1) and the multi-spectral Moderate Resolution Imaging Spectroradiometer (MODIS) image data. The comparison is made by visual evaluation of three-color combination images of IHS, PCA, CN and HPF results based on spatial and spectral characteristics. The use of a contrasted EOC panchromatic image as a substitute for intensity in merged images with MODIS bands 1, 2 and 3 was found to be particularly effective in this study.

A suitable pan-sharpening method has to be chosen with respect to the used spectral characteristic of the multispectral bands and the intended application. The research on pan-sharpening algorithm in improving the accuracy of image classification has been reported. For a classification, preserving the spectral information is important. Other applications such as road detection depend on a sharp and detailed display of the scene. Various criteria applied to scenes with different characteristics should be used to compare the pan-sharpening methods. The pan-sharpening methods in our research comprise rather common techniques like Brovey, IHS(Intensity Hue Saturation) transform, and PCA(Principal Component Analysis), and more complex approaches, including wavelet transformation. The extraction of matching pairs was performed through SIFT descriptor and Canny edge detector. The experiments showed that pan-sharpening techniques for spatial enhancement were effective for extracting point and linear features. As a result of the validation it clearly emphasized that a suitable pan-sharpening method has to be chosen with respect to the used spectral characteristic of the multispectral bands and the intended application. In future it is necessary to design hybrid pan-sharpening for the updating of features and land-use class of a map.

A biuret method by Johnson and Craney (1971) was slightly modified and applied to the multiple analysis of nitrogen in brown rice. The results were compared with those by the dye-binding method to see if the former be applicable to the determination of higher nitrogen content in rice. The nitrogen content of rice samples ranged from $1.2{\sim}2.0%$. The correlation between biuret absorbance and nitrogen content was highly significant; its correlation coefficient being 0.841. The biuret method, however, showed rather lower correlation coefficient in case of high nitrogen samples.
