In designing Intelligent Traffic Systems, it should be necessary to consider telecommunications, appearance, environment, auxiliary functions, safety, and so on. Also, in choosing a car, a consumer considers those properties. This paper tried to elucidate the fact that car color has a very significant meaning for car safety when administrating intelligent traffic services and making car-purchasing decision. We first studied on occurrence probability of car accident according to car color that has something to do with car safety. Then, we studied on the concepts of advancing color and receding color. Advancing color causes less accidents since the color looks closer than it actually is. And receding color causes more accidents since the color looks farther than it actually is. And we classified car colors into eight classes and assign their ranking to each class, considering the number of car accidents. We tried to verify our research by use of telephone questionnaire for residents in Kunsan, Republic of Korea.

In the present study, the seed color of 200 common bean genetic resources was analyzed and located on the HTML color chart to classify these resources according to color characteristics. This classification method predicts the components of seed and may serve as a new method for efficiently using secured genetic resources. The imagary data of common bean exhibiting various seed colors were expressed using the HTML color chart. According to the proposed classification method, the seed color was distributed in seven categories: yellow-green, yellow, brown, red, white, gray, and indigo. In addition, the distribution of each seed color was according to its concentration. The distribution by concentration was the highest for red, whereas the distribution of gray and yellow-green was not concentration-dependent. As the dominant pigments based on color distribution, chlorophylls in yellow-green; carotenoids in yellow; and anthocyanins in brown, red, white, gray, and indigo significantly affected seed color. When expressed objectively, seed colors can be applied to the systematic management, breeding, and cultivation of genetic resources and can be useful for marketing or developing products of desired colors. This method can also be applied to other crops.

The temperature is a sense that can be felt by touch and sight. However, the concept of the temperature sensation is rarely used together with the concept of visual sensation and tactile sensation. In this study, the sensation of the temperature sensed through tactile and visual sense was investigated by the visual temperature depending on color and material characteristics. The textile was selected as a sample that could include color and material characteristics. The textile sample was composed of each 15-16 kinds of Yellow, Red, Blue, and Green of total 90 samples. The analytical method was to analyze first, the warm-cool of the colors of Yellow, Red, Blue, Green, and then to the visual temperature according to visual classification and tactile classification. And we investigated the correlation of the visual temperature depending on weight, thickness, and unevenness. As a result, the number of textiles felt by Cool and Warm differed according to the warm-cool of the colors feeling in the same textile. However, the visual temperature was different to each classification of textile. In particular, it was noticeable in thin, see-through and matte textiles. In relation to weight, thickness, unevenness and the visual temperature, the textile classification related to the weight is a classification of a hard, matte textile, and the textile classification related to the thickness is a thin, see-through textile.

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.

The taxonomic status of a new forma, Opuntia humifusa (Raf.) Raf. f. jeollaensis E. J. Kim & S. S. Whang, and the taxonomic relationships of three Korean cladodes were studied based on DNA sequences of three genes. The new forma O. humifusa f. jeollaensis (Wanggasi-Chunnyuncho) is simlilar to O. humifusa (Chunnyuncho), but differ in having both flower with the reddish inner center, and strong and many 3 cm long spines. Molecular studies showed that the new forma grouped into Macrocentra series instead of Humifusa series which included Korean O. humifusa. We designated the new taxa firstly studied here as a new forma, because the taxa have been mainly cultivated in farmlands in Jeolla-do area rather than distributed in nature. The taxonomic relationships of three Korean cladodes are discussed in detail.

A new species, Epilobium ulleungensis J. M. Chung (Onagraceae Juss), from Ulleungdo Island (South Korea) was described and illustrated. Among four taxa native to Ulleungdo Island (E. amurense Hausskn. subsp. cephalostigma (Hausskn.) C. J. Chen, Hock & P. H. Raven, E. hirsutum L., E. pyrricholophum Franch. Sav., and E. ulleungensis), E. ulleungensis has a unique tetragonal stigma, which is considered to be an intermediate form between clavate (E. pyrricholophum) or capitate (E. amurense subsp. cephalostigma) and 4-lobed stigmas (E. hirsutum). More importantly, this new species is clearly distinguished from the other three taxa distributed on Ulleungdo Island by its height (over 200 cm), decumbent stem, leaf shape, short, dense pubescent covering on the whole plant, large flower size, and a dark pink or red purple flower. According to the stigma shape and other characters, it was estimated that E. ulleungensis is a hybrid between E. hirsutum and E. pyrricholophum or E. amurense subsp. cephalostigma). The specific epithet "ulleungensis" was chosen because the new species was restricted to Ulleungdo Island.

일반적으로 인간은 외부로부터 정보의 85% 이상을 '시각'을 통해 얻고 있으며 색(色)-형(形)-Texture(質感)의 순으로 사물을 인식한다. 그래서 인간은 예전부터 위험상황에 대응하기 위해 대상의 정보를 신속하게 전달하는 수단으로 색채를 활용해 왔으며, 안전색채는 이러한 색의 속성을 이용 위험으로부터 안전을 확보하기 위해 적용되어왔다. 현재 안전에 관한 정보를 제공하는 시스템에는 언어나 문자사용을 가능한 한 사용하지 않고 안전표지를 국제적으로 표준화하여 사용하는 것이 바람직하며 실제로 국제표준기구(ISO)가 제정한 '안전색채 및 안전표지(ISO3864)'를 채택하거나 자국의 실정에 맞춰 일부 변경 사용하고 있다. 또한 안전표지는 색만이 아니고 그것을 표시하는 형까지 포함 사용되며 형태는 표시 물건에 따라 다양하며 또한 색채가 일으키는 심리 작용을 이용하여 주의를 환기하거나 위험을 경고하며 위험방지 및 긴급사태에 대한 대응을 목적으로 하고 있다. 안전색채 및 안전표지의 목적은 안전 및 건강에 영향을 미치는 대상물 및 장소에 신속하게 주의를 촉구하는데 있다. 따라서 본 연구에서는 안전색채와 안전표지에 대해 알아보고 이를 사용한 실례를 통하여 안전색채와 안전표지의 색채 및 디자인에 대해 알아보고자 한다.

A lot of image quality assessment metrics that can precisely reflect the human visual system (HVS) have previously been researched. The Structural SIMilarity (SSIM) index is a remarkable HVS-aware metric that utilizes structural information, since the HVS is sensitive to the overall structure of an image. However, SSIM fails to deal with color difference in terms of the HVS. In order to solve this problem, the Structural and Hue SIMilarity (SHSIM) index has been selected with the Hue, Saturation, Intensity (HSI) model as a color space, but it cannot reflect the HVS-aware color difference between two color images. In this paper, we propose a new image quality assessment method for a color image by using a CIE Lab color space. In addition, by using a support vector machine (SVM) classifier, we also propose an optimization system for applying optimal metric according to the types of distortion. To evaluate the proposed index, a LIVE database, which is the most well-known in the area of image quality assessment, is employed and four criteria are used. Experimental results show that the proposed index is more consistent with the other methods.

The study was conducted in patients who had undergone angiography and arterial embolization after being diagnosed with arterial bleeding among those registered with severe trauma at the admission to the department of emergency due to accidents. In the study, comparison was done between the survived group and the nonsurvived group to investigate the usefulness and the optimal performance timing of angiography and embolization as the survival-affecting factors and treatment methods for patients. The study was performed as a retrospective analysis in 45 patients who had undergone angiography and arterial embolization among those categorized as severe trauma patients from the emergency department of H hospital located in Gyeonggi-do from July, 2006 until December, 2010. The Injury Severity Score (ISS), the Revised Trauma Score (RTS), the hematocrit were the main outcome measurements. Arterial embolization was technically successful in all cases, transcatheter arterial embolization of arterial bleeding is a useful procedure in lowering the mortality and complication in severe trauma patients. and RTS, ISS, Hematocrit were the predictable early mortality factors. So bad vital sign patients must be progressed rapidly.
