Korea Institute of Construction Materials founded Seosan Outdoor Exposure Test Site 2005 at Korea, which is a part of Worldwide Exposure Network (WEN). To evaluate the test site along with other exposure test sites, three different types of paints have been under real time weathering conditions at three major weathering test facilities around the world. Using these test specimens several spectroscopic experiments along with physical tests have been performed. Also acceleration tests have been performed using the same paints. The correlation of weathered paints among three different test facilities and accelerated test results has been compared. From the results the reliability of Seosan Weathering Test Facility and reasonable life time prediction tests are discussed.

The Ministry of Construction and Transportation (MOCT) has been constructing a nationwide soil information DB since 2000, as basic data for the construction of 'underground geographical information,' a project under the 2nd National Geo-spatial Information System (NGIS) master plan. The inputted soil information includes not only underground conditions such as the layer depth, type, color, and groundwater level, but also engineering information that can be applied to construction work design, such as on the standard penetration test and the compression test. It is difficult to use this information in soil analysis and design, however, because only the test results are currently available. A web-based geo-spatial information system was developed in this study to facilitate the effective application of the soil information database (DB). First, the space information, layer information, and engineering test information were loaded from the soil information DB in real time, and the earth volume, bearing capacity, and settlement were calculated to develop a web client that will evaluate the ground softness and liquefaction. It seems that the soil information DB can be actively applied to the planning and design of construction works using this system.

We focus our attention on grading of table meat in accordance with the standard of Japan Meat Grading Association, and construct a beef grading system by image processing. For image processing of beef grading, it needs some techniques such as a shading correction, separation of color image data, and classification of color image data into some grades, for the system construction. However, there are various kinds of weak points in usually used methods for these techniques. Then the authors propose and introduce new approaches using Neural networks and fuzzy inference for the techniques above mentioned, which is very convenient and ensure the high precision.

In this paper, we propose a new single-image dehazing method. The proposed method constructs color ellipsoids that are statistically fitted to haze pixel clusters in RGB space and then calculates the transmission values through color ellipsoid geometry. The transmission values generated by the proposed method maximize the contrast of dehazed pixels, while preventing over-saturated pixels. The values are also statistically robust because they are calculated from the averages of the haze pixel values. Furthermore, rather than apply a highly complex refinement process to reduce halo or unnatural artifacts, we embed a fuzzy segmentation process into the construction of the color ellipsoid so that the proposed method simultaneously executes the transmission calculation and the refinement process. The results of an experimental performance evaluation verify that compared to prevailing dehazing methods the proposed method performs effectively across a wide range of haze and noise levels without causing any visible artifacts. Moreover, the relatively low complexity of the proposed method will facilitate its real-time applications.

We defined life style as something that every members of society have in common. These social and cultural environments build up not only society group or every individual's expectation but also its own life style. In that way, these social and cultural environments leads to particular consumer behavior pattern in this food-service industry. So we regard next generation's trend which consists of rational consumers as important indicator when we make future's plan in foodservice industry. We consider smart map which needs rational and continuous consume pattern as the construction of next generation's main consumer class. Therefore, this study tried to develop of color and image marketing strategies to attract LOHAS and nomadic consumer.

Water management treatment of coastal region has been an important problem in Jeju city since the distributions of pipeline of the pumping system made a bad view in coastal region. To solve the problem, we observed the pipelines that are on the surface around the coastal region from Tapdong to Doduhang. From the observations, we found that Todong and Dodu areas were not unsightliness because the all pipelines were located in underground. However, the other areas, such area Yongdam, Handugi, Yongdam fishing village, had a serious problem for the coastal landscape view. To solve the problem, at we estimated coastal land color characteristics of Jeju city based on the observation of the pipelines. The estimated color panel shows that the green, blue and grey colors are a dominant factors of the Jeju coastal region. Based on the color panel, we proposed two methods, that is, one is a short time treatment, the other is a long time one. The short is based on the colour treatment, which is pipeline colour changing into surround natural one. The long time is the construction plan design method. Although the later method was very useful in Jeju island. However, it takes a lot of time and money. Therefore, in the situation, the short time is the better than the long time one.

This study examines the unique characteristics of the color red in relation to images used in areas other than fashion, such as the film or advertising industries. Based on analysed results, the aim was to identify red-colored costume's images expressed in contemporary fashion. Analysis of collected data has lead to four main findings. First, the fashion in which the red color is used delivers a voluptuous image when combined with a skinny silhouette or glossy and transparent dress material, arousing a strong sexual desire in a direct or indirect manner when exposing the body in public. Second, the fashion emphasizes a simplified appearance by minimizing the steps of the production process such as cutting, sewing, and decoration without artificial structural lines and creates an image of simplicity through a single red color or tone-in-tone colorations. Third, the red color, which carries a simultaneous negative and pleasure image represents grotesque playfulness by distorting or exaggerating clothes, transforming the body in disregard of clothing construction, or introducing unnatural makeup. Fourth, in combination of simple and clinging shapes, a material feeling tough like leather and an intensely noticeable red tone, promotes the feminine rather than masculine quality in a splendid, aggressive sporty and active "alpha girl" image.

The purpose of this study was to investigate the differences in the dissatisfaction with and design preferences for mountain gear among the segments divided by specialization activity-pursued for recreational mountaineering. Data were collected by questionnaire survey from 900 subjects with the experiences of mountaineering and purchasing mountain gear in the past year, and 891 were used for the data analysis. The results of the study were as follows: Three factors were formulated based on mountaineering specialization activity-pursued: expertise-pursued mountaineering, mountaineering with psychological attachment and activity-oriented mountaineering. Four segments were identified based on the specialization activity-pursued: the emotionally-committed, the continuously-participated, the expertise-pursued, and the passively-participated. Significant differences were found in dissatisfaction with and design preference for mountain gear among the segments. The expertise-pursued tended to be more dissatisfied with color and fabric than the others, and preferred various mountain gear design of shape, color combination and construction line. On the other hand, the passively-participated tended to prefer simple and comfortable style with solid color and simple color combination.

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.
