본 연구의 목적은 퍼스널컬러를 정량적으로 진단할 수 있는 모델을 구축하는 것이다. 현재 사용되고 있는 대표적인 퍼스널컬러용 색채 시스템들은 퍼스널컬러 진단 유형을 지나치게 단순화하거나, 진단 유형간의 객관화된 차이를 구별하기 어렵다는 한계를 가진다. 이를 보완한 새로운 색채 시스템을 개발하기 위해 논리적 배색이 가능한 PCCS 색체계를 도입하고, 색이 가지는 주요 4속성을 토대로 재분류하였다. 기존 색채 시스템보다 다양한 20개의 진단 유형을 제안하였으며, 정량적 방법을 피험자와의 어울림 정도를 평가하여 최적화된 유형을 찾을 수 있게 하였다. 평가 결과를 기호화하여 대입하면 피험자에게 맞는 유형이 도출되는 매트릭스를 고안하여 실험자의 개별 역량과 주관의 개입을 최소화하였다. 최종적으로 속성진단, 기호화, 계절진단의 세 단계로 이루어진 퍼스널컬러의 정량적 진단 모델을 구축하였다. 이는 기존 진단 방법에 다양성, 신뢰성, 정확성을 부여할 것이라 볼 수 있다.

The purpose of this study was to analyze the meaning and formative features of the black color reflected on the fetish fashion. This study was proceeded mainly by analyzing with references and plates of magazine. The results of the study were as follows ; First, the sexual liberation and revolution have certainly led to a reassessment of sexual deviations, which changed the meaning of fetishism that has been only regarded as sexual perversion, so that it symbolied a new sexual perception and identification. As the result, black in fetish fashion was symbolized a new fetishism\`s definition which refused to distinguish male from female, and also reflected the meaning to express the second sex that wanted to express themselves. Second, the formative features of black color in fetish fashion have appeared tightness and bareness in form, and in material, glancing materials changed by the effect of light, and elasticity materials-leather, rubber, PVC, and laycra. By these features, black fetish fashion has drawn a higher attention on human body than the dress itself as a symbol about the psychology of erotic sensations and sexual images of the self appearing in black color.

The purpose of this research is to study face images according to color of make-up was made by computer graphic simulation. The various facial images can be helpful for choosing suitable make-up color planning. In order to find out the differences of face images by make-up color, three different foundations and seven eye-shadows, six lips were applied on the round face model. Make-up Image Scale was used the scale of seven point modified the S-D method. Data were analyzed by Varimax perpendicular rotation method, Duncan's Multiple Range Test, Three-way ANOVA. As the result of make-up image perception analysis, a factor structure was divided into mildness, modernness, elegance, unique. The factor of mildness, modernness, unique affected on the foundation color. Foundation color was found out to be influential variable to distinguish color perception abilities. Also, the foundation, eye-shadow, lip color were influenced interactively on the perception of elegance factor. Pink color was important color, influenced on the mildness factor. Gray and purple color were influenced on the modernness factor. Mildness factor was perceived as the most bright foundation but unique factor was perceived as the most dark foundation. Then, the foundation, eye-shadow, lip color were influenced interactively on the perception of facial images. The results can be effectively applied to today's marketing and color design management which is focused on the product's emotional image in customer's mind.

The spectroscopic characteristic of 9 items in the urinalysis strip are measured to develop the urine analysis system. From experimental results, we determined the wavelength range which could accurately distinguish the degrees of 9 test items. Simulation is performed to distinguish the primary color reaction in the urinalysis strips using reflectance of urine strips, luminous intensity of LEDs, and spectral sensitivity of photodiodes. The simulation results agree well with experimental results by using UV-Visible spectrophotometer.

This study analyzed the system and arguments on the light-pink official uniforms and investigated the backgrounds and principles on the changes of the Sibok system. A study on light-pink danryeong in the latter part of the Joseon Dynasty is a de facto study on Sibok since the name of the light-pink official uniforms (implemented at the time of King Seonjo) changed from Sangbok to Sibok. Sangbok is discussed to explain the name change from Sangbok to Sibok and distinguish their usages; in addition, Gongbok is examined to understand the characteristics of the Sibok system. The Annals of the Joseon Dynasty (books written by scholars) and related laws are used as research materials. The research results are as follows. The name of the light-pink uniforms (a custom before the Japanese invasion in 1592) changed from Sangbok to Sibok at the time of King Gwanghaegun and the light-pink uniform was used as a relatively light formal uniform compared to Sangbok. Sibok was added to the law Sok-dae-jeon at the time of King Yeongjo (because the king respected the custom) and its color rank system was denoted from light-pink and red. Sibok was revised to light-pink, blue, and green under the law Dae-jeon-tong-pyeon that was promulgated at time of King Jeongjo. In the development of the Sibok system in the latter part of the Joseon Dynasty, the color rank system of Gongbok was reflected. The sovereign ideas in the official uniforms in the latter part of the Joseon Dynasty (revealed in the study of the system and arguments on the light-pink official uniforms) were the thoughts that respected the custom and the principles that distinguish ranks to establish a Confucian based hierarchy.

This is a fundamental study to develop a sensor to detect weeds in paddy field using machine vision adopted spectralphotometric technique in order to use the sensor to spread herbicide selectively. A set of spectral reflectance data was collected from dry and wet soil and leaves of rice and 6 kinds of weed to select desirable wavelengths to classify soil, rice and weeds. Stepwise variable selection method of discriminant analysis was applied to the data set and wavelengths of 680 and 802 m were selected to distinguish plants (including rice and weeds) from dry and wet soil, respectively. And wavelengths of 580 and 680 nm were selected to classify rice and weeds by the same method. Validity of the wavelengths to distinguish the plants from soil was tested by cross-validation test with built discriminant function to prove that all of soil and plants were classified correctly without any failure. Validity of the wavelengths for classification of rice and weeds was tested by the same method and the test resulted that 98% of rice and 83% of weeds were classified correctly. Feasibility of CCD color camera to detect weeds in paddy field was tested with the spectral reflectance data by the same statistical method as above. Central wavelengths of RGB frame of color camera were tried as tile effective wavelengths to distingush plants from soil and weeds from plants. The trial resulted that 100% and 94% of plants in dry soil and wet soil, respectively, were classified correctly by the central wavelength or R frame only, and 95% of rice and 85% of weeds were classified correctly by the central wavelengths of RGB frames. As a result, it was concluded that CCD color camera has good potential to be used to detect weeds in paddy field.

It is possible to enhance the color of the natural diamond with a high pressure high temperature(HPHT) process. We employed a pyrophyllite tube cell and cubic press apparatus for HPHT treatment on the brown colored Type II (5.6 GPa/ $1700^{\circ}C$/ 52 min), and Type I aB(5.6 GPa/ $1650^{\circ}C$/ 30 min) diamond samples. We investigated the microstructure, Types, fluorescence, properties of the diamonds with an optical microscopy, FT-IR, photoluminescence(PL) spectroscopy, Diamond-View, and micro-Raman spectroscopy. Two tinted brown diamonds changed into colorless just after the HPHT process. Optical microscopy showed that no crack and significant inclusion evolution occurred during the HPHT process except the small graphite spot appeared in Type I aB sample. FTIR spectrum confirmed that no Type, amber center, and platelet defect change with the HPHT treatment. Diamond-View could not distinguish the HPHT treated diamonds from the naturals. PL spectroscopy showed that N3 and H3 color centers remained even after HPHT process. Consequently, we successfully changed the color of diamonds into colorless by 5.6 GPa HPHT process.
