In this paper, a method of detecting the emergency situations such as body fall is proposed by using color images. We detect body areas and key parts of a body through a pre-learned Mask R-CNN in the images captured by a camera. Then we find the centerline of the body through the joint points of both shoulders and feet. Also, we calculate an angle to the center line and then calculate the amount of change in the angle per hour. If the angle change is more than a certain value, then it is decided as a suspected fall. Also, if the suspected fall state persists for more than a certain frame, then it is determined as a fall situation. Simulation results show that the proposed method can detect body fall situation accurately.

In this paper, we propose the modified display color control system using white point line, boundary lines and S-shaped curves to emphasize blue and red tone colors on CIE1931 diagram. The proposed system divides RGB gamut into movable area and non-movable area by using boundary lines. The colors in movable area are moved into right side or left side along quadratic curve to change the bluish (or reddish) color to more bluish (or more reddish), while those in non-movable area are excepted from color control to prevent skin color from changing. The loci of the quadratic curves are very similar to the arc of the white-point line which connects all points that represent the chromaticities of a black body radiator at different temperatures and is also called the black body locus. The RGB gamut extension by movement of chromaticity coordinate can improve color reproducibility. Therefore in the case of application to LCD, the display shows excellent performance because the LCD's color reproducibility is comparatively lower than that of other display systems. The proposed system is also experimentally demonstrated with Xilinx Virtex FPGA XCV2000E- 6BG560 and the TV set.

It fuses into culture of the East and the West in use of color ; colors of five direction, which had been from the Five Phase Theory in East Asia. Formative ability of color fields in a formative early Oriental Medicine history as well. Color is a very important factor and a necessary step of visible diagnosis. As a human's body is maintained and alive under the control of spirit and spirit is stored by five viscera, so spirit expresses the change of five viscera and is reflected by color. Visible diagnosis consists of spirit, appearance, Qi and color and movement. The purpose of each visible diagnosis is that we would know states of essence, Qi and spirit in patient's body. To ancient Asia people 'to see' was a kind of insight to the object as a whole. Similarily the activity of seeing the human body was the integral part of making diagnosis of a patient. This was the cause that there was suggested the discussion of the Five color theory in Oriental Medicine as a counterpart to that of the 'Goethe for Zur Farbenlehrer'. The inspection of Oriental Medicine was not a simple gazing of the eye as a sense organ, but the total insight to the internal state of the patient. For that reason, the eye－perception in early Chinese medicine was the reading the signs of the internal body which had have not the visual form but the flux of the internal life.

The wild silkmoth, Samia cynthia pryeri, was firstly collected at Miryang, Korea. The development and quantitative characters of S. cynthia preyri in the laboratory condition were analysed. The larval body color of dark yellow green or light yellow green of the S. cynthia pryeri was changed into white color during the molting period, and the yellowish bristles in younger larvae were changed into fade green color in advanced stage larvae. Aralia elata and Zanthoxylum piperitum were newly identified as host plants to S. cynthia pryeri. Cocoon weight and cocoon shell percentage were average 2.14 g and 12.3 %, respectively. In addition, the morphology of the silkgland was different from that of the domestic silkworm,Bombyx mori, but was identical with that of the wild silkmoth, Antheraea yamamai.

Jang Nam's opinion is that Yin-Yang of pathogenic factors change following to the Yin and Yang of human body. As the pathogenic factors injure the human body, the conditions of diseases become different to the inborn constitution of human. Therefore the main principles of remedy set up the diagnosis on the YINㆍYANG & the strengthㆍweakness of constitution. This diagnotic points are body formal distinction, flesh hardness and softness, face color and form, skin color. Moreover he arranges the 4 type of the hole-body constitution based on the Seop-Gye's the guide of clinical differentiation of syndromes(臨證指南); Yang-Strength and Yin-weakness(陽盛陰虛), Yin ㆍYang-strength(陰陽具盛), Yin-Strength and Yang-weakness(陰盛陽虛), YinㆍYang-weakness(陰陽兩虛).

Objectives From observing the tongue of a patient, one can assess the health status; this method has been frequently used in traditional Korean Medicine (KM) clinics. In particular, KM posits that the color of the tongue is highly related to digestive functions. In this study, the color of tongue and heart rate variability (HRV) were compared between chronic dyspepsia (CD) patients and healthy subjects. Methods Healthy subjects and CD patients with functional dyspepsia (FD), gastroesophageal reflux disease (GERD), or chronic gastritis (CG) were enrolled for the study. Profile view images of the tongue were acquired by using a computerized tongue image acquisition system (CTIS). The color of the tongue body was extracted from the non-coated region on the tongue images. Results Color differences in CIE L*a*b* color space between the three sub-types of CD patients and healthy subjects were analyzed by using multiple linear regression analysis with age and sex as the factors. The variable b* was significantly lower in GERD patients than in the controls (p=0.017). Variable a* was significantly lower in CG than in the controls (p=0.03). No significant difference was seen between FD and controls. In GERD, the tongue body seems to be intense red in color; in CG, pale red. Frequency domain analysis showed that HF was significantly lower in GERD patients than in the controls (p=0.041). Conclusions The color of the tongue body and HF of HRV can be used for diagnosing digestive functions in health care.

Experiments designed to measure the effect of LED (light-emitting diode) light wavelength on the growth of fingerling rockfishes (Sebastes inermis) were conducted. Fingerling rockfishes (average body weight of individual: 1.13g) were divided into two groups by wavelength of the LED light [light power: 1,620 mW; wavelength: 518 nm (green color), 622 nm (red color)]. Triplicate groups of 180 individuals were reared over 7 weeks. Lighting duration was 14 hours from 06:00 to 20:00. A water tank exposed on the natural light in a room through the windows was used as a control. At results of the first experiment [initial average body weight (BW) of individual: 1.13 g; standard deviation (SD): 0.13 g], the final individual BW exposed on the green color was increased 0.39 g than the red color, and decreased 0.12 g than the natural light in the room. At results of the second (initial individual BW: 5.07 g; SD: 0.70 g) and the third experiment (initial individual BW: 10.67 g; SD: 0.67 g), the final individual BW exposed on the green color was increased 1.07 g and 2.55 g than the red color, respectively, and increased 0.57 g and 0.84 g than the natural light, respectively. The relative growth rate of the green color was higher about 8% significantly (p<0.05) than the natural light. In the case of the red color the relative growth rate was lower significantly (p<0.05) than the natural light.

The purpose of this study was to show the analysis system and the expression which is applied to fashion illustration by three major components in visual sign, metaphor and metonymy. The results of this study were as follows : Firstly, metaphor in qualisign of syntactics was revealed as a color such as realistic description, a pattern such as clothing of figure. etc. Metonymy was revealed as a social and cultural background color, a concept pattern. etc. In sinsign of syntactics. metaphor was revealed as a human body, non-human body and metamorphosis human body and metonymy as a human body and non-human body. In legisign of syntactics, the metaphor by perspective was used for a fantasy of space. and the metonymy was revealed as a color perspective representation, etc. The degree of change of texture was revealed as a metaphor and metonymy of gradation. And conventional custom sign was almost revealed in metaphor. Secondly, semantics showed about fashion image as juxtaposition of two similar objects in metaphor and as real description and simplification in metonymy Alternative fashion image in semantics was presented as a object related to fashion image. Conventional symbolic sign was presented as a role to clarify a fashion message in metaphor. Thirdly, the metaphorical and metonymical expression in pragmatics were usually presented as drawing and painting.

This study is to be investigated through firing experiment in studio in order to reveal a physical properties of celadon according to change firing temperature. The results can be briefly summarized as below; Firstly, in measurement of color chromaticity, samples of first firing in body were effective in differentiating of changed color in samples from each other but there of second firing were not. The color of the glaze was more effective change than that of the body. Secondly, bulk density of body was increased with temperature and it was attained highest point in $1200^{\circ}C$ Additionally, water absorption ratio was most rapidly changed between $1000^{\circ}C$ and $1200^{\circ}C$Thirdly, in the microstructural analysis, body of samples in first firing have not specific characteristics in the changed patterns of microstructure. body and glaze of samples in second firing have many that. Consequently, we knew that this experiment can be provided researcher with physical properties and firing mechanisms of celadon.

The purpose of this study was to investigate the effect of physical type and age on preference for color and fabric motifs in women's clothing design. Color preference measures consisted of fabric samples in solid colors and drawings of clothing styles painted in colors. Preference for fabric motifs was assessed by printed fabrics in various patterns and sizes. All of the preference measures were devised specifically for this study. Furthermore, items on height and weight for physical type as well as age of the subjects were included in the questionnaire. Data were obtained by means of structured interviews and self-administered questionnaires from 588 women ($20\~60$ years of age) in seoul. Analysis was by chi-square ($X^{2}$), frequency, percentage, and mean. On color preference, a small but significant body type, height, and age effect was found on some types of clothing. Preference for fabric motifs was affected by body type; height of subjects was related to preference for size of motifs, and age was related to choice, size, and width of striped motifs. It was concluded that body type, height, and age are 1e3st effective in predicting color preference. Fabric motif preference was influenced more by age than by body type or height. Generally, there was some similarities in preference for lines and fabric patterns among slim body types, tall figures, and younger age groups as well as heavy body types, short figures, and older age groups.
