Urine measurements by MNR were made for 25 persons including cancer and non-cancer patients. The aromatic proton signals of NMR wer observed much more often in cancer patients' urine than non-cancer patients' one. To compare the amount of the phenolic compounds excreted in urine between cancer and non-cancer patient, urine analysis by HPLC with UV detector was performed. Total peak area and major peak areas of cancer patients' urine wer emuch greater than those of non-cancer patients' one. To check the phenolic compound excreted in urine, a new jellied reagent named Gift reagent which was based on Millon's reagent, was developed for urine color reaction. When the reagent was tested, the sensitivity and specificity for urine samples of 69 persons including cancer and non-cancer patients were measured by 85.3% and 91.4%, respectively, indicating that the Gift reagent afford a possibility of cancer diagnosis.

Maillard 반응중 피질의 변화를 4차원 반응표면으로 나타내어 기질의 동적변화를 모니터링하고자 하였다. Total amino acids의 함량변화에 대한 회귀분석 결과 높은 $R^2$ (0.9470)를 나타내었으며, 각각의 amino acid또한 높은 R'를 나타내어 대부분 유의성이 인정되었다. 유리당의 함량에 대한 회귀분석에서 glucose의 함량에 대한 R'는 0.9250이었으나 fructose에 대한 $R^2$는 0.6490으로 낮은 값을 보였다. Maillard반응중 total amino acids의 함량은 반응온도가 높고 용매의 pH값 이 증가할수록 크게 감소되었다. 반응생성물의 갈색도는 반응온도가 증가할수록 증가하나 145‘C 내외에서 최대값을 나타내었다. 각각의 amino acid함량변화는 total amino acids 함량인화와 유사한 경향이었으며, 4차원 반응표면분석 결과 aspartic acid, threonine, glucose등의 기질들은 복합기질계 Maillard반응에 있어서 특이하게 반응온도가 증가할수록 크게 감소한 반면, 용매의 pH와 반응시간의 영향은 거의 받지 않는 것으로 나타났다.

Urine NMR analyses made by use of an 80 MHz proton NMR spectrometer show that aromatic proton NMR signals appear in most censer patients'urine. On the assumption that the signals may be caused by the phenolic compound of tyrosine excreted in the urine, a jellied reagent is used for identifying them by observing the urine color reaction. It is observed that the reagent reacted to the cancer urine becomes red. Such a change of the urine color seems to indicate the substance of tyrosine. Recently an attempt to determine the reagent sensitivity an specificity of the urine of 69 persons including cancer and noncancer patients has been made. The results of the attempt are respectively 85.3% for sensitivity and 91.4% for specificity. This seems to show a possibility that the reagent can be used for the diagnosis.

A simple and rapid colorimetric method for determination of panaxadiol and , panaxadiol was developed. 1. After heating with 60% perchloric acid, panaxadiol and panaxadiol yielded red.purple color with absorption maximum at 540 nm and 538 nm, respectively. 2. The maximum colors of the Panaxadiol and panaxadiol were reached when the algycones were treated at 6$0^{\circ}C$, 5 minutes or 7$0^{\circ}C$ 3 minutes. 3. The absorbance varied linearly with the amount of aglycone in the reaction mixture. And the colorimetric method was sensitive to about 10$\mu\textrm{g}$ of aglycone in 5.5ml of the reaction mixture. 4. The color was stable for about a week at 4$^{\circ}C$. 5. $\beta$-Sitosterol, oleanolic acid and cholesterol were not yielded red color by treatment with 60% perchloric acid under the conditions described.

본 논문에서는 RGB 색상의 파장과 크기를 사운드로 생성할 수 있는 특성화된 주파수와 진폭으로 변환시키는 방법을 제안하였다. 제안된 방법으로 입력된 동영상의 각 프레임에서 SAD를 통한 모션 에너지의 변화량에 따라 분할면의 반응을 4개로 나누고, 객체의 흐름과 움직임을 파악하였다. 또한, 칼라값을 통하여 동영상의 의미를 사운드로 모델링할 수 있음을 보였다.

Purpose: This study aims to examine the effects of pulsed ultrasound on skin inflammatory reaction induced by ultraviolet irradiation. Methods: Twenty subjects were selected for this study. Inflammatory reaction was induced by ultraviolet irradiation in two areas of the lumbar region of the subjects. Pulsed ultrasound (3 MHz) was applied to one of the two areas of inflammatory reaction at a pulse ratio of 1:4, intensity of $0.5W/cm^2$, once a day for 5 min, and pulsed ultrasound was not applied to the other area. Wound color (chromatic red), luminance (gray) and wound contraction (area) were measured using digital imaging processing method. Results: There was a significant difference in wound color (chromatic red) in the interaction between time and area. There was a significant difference in luminance in the interaction between time and area. There was a significant difference in wound contraction between the two areas. Conclusion: These results indicate that pulsed ultrasound increased the wound contraction rate and reduced the inflammatory reaction activity such as erythema induced by ultraviolet irradiation.

A Belousov-Zhabotinsky reaction in a liquid-liquid system under microwave radiation was observed under non-stirring conditions. To control this non-equilibrium reaction, nano-particle, which is active under microwave irradiation, was added to the solution. Color changes of the solution during the oscillatory reaction were found to be influenced by the irradiation power although the droplet temperature was equal to the temperature of surrounding oil. During the irradiation, the period of oscillation became shorter because the reaction rate was faster. It could also be observed that there is possibility to eliminate oscillatory behaviors of the reaction using higher power of microwave. The possibility of controlling non-linear reaction using microwave was shown since microwave can easily travel through oil phase and reach water phase.

This study aimed to provide the basic data of the establishment of marketing strategies by dividing consumer groups in accordance with the pursuit of clothing benefit, and then understanding the importance of clothing selection criteria in those groups, whether there are any differences in it between groups, and whether there are any differences in preference of clothing color depending on the mood state of those groups. The scale of this study was comprised of the pursuit of clothing benefit factors, clothing selection criteria factors, and the factors related to preference of clothing color by each mood state. In the results of the analysis, the factor most considered when male and female consumers in 20s~30s purchase clothing was fitting, and followed by convenience, stable shape, condition, design, and others' reaction in order. However, those 'design', 'convenience', 'others' reaction' and 'condition' factors were significantly different between groups. Therefore, the significance of this study is that fashion brands could develop new positioning maps for marketing and promotional strategies based on the pursuit of clothing benefit shown in this study.

자색고구마 anthocyanin 색소의 가열에 의한 변색반응에 대한 kinetic 상수를 온도 $121{\sim}141^{\circ}C$의 범위에서 조사하였다. Browning index를 사용하여 조사한 자색고구마 색소의 변색반응은 2차반응을 따랐으며, pH를 각각 2.0, 3.0, 4.0 및 5.0으로 조절한 자색고구마 색소의 활성화에너지는 69.57, 76.68, 81.07 및 92.98 kJ/mol로서 용액의 pH가 증가할수록 가열변색에 대한 온도의존성이 커짐을 알 수 있었다. 각 반응의 지수앞 인자와 활성화에너지 사이에는 kinetic compensation effect가 있음을 알 수 있었는데, 이는 이들 색소액의 가열변색이 같은 기작에 의해 이루어짐을 의미한다.
