  • Preparation conditions for germinated brown rice gruel on its sensory quality were optimized using response surface methodology. Water volume ratio to germinated brown rice significantly affected the sensory quality of germinated brown rice gruel. Sensory quality, such as color, flavour, and overall acceptance increased significantly when milk ratio was increased. R2 of response surface equations were 0.9076, 0.9634, 0.9555, 0.9677 and 0.9769 for color, viscosity, flavour, mouthfeel and overall acceptance respectively (p<0.01). Optimum preparation conditions on overall acceptance for germinated brown rice gruel were: water volume ratio 8.26, cooking time 31.98 min, cooking temperature 95.71$^{\circ}C$ and milk ratio 0.54. High correlation was found between viscosity, flavour, mouthfeel, and overall quality.

  • Color of kimchi juice was measured instrumentally to evaluate the quality of Korean cabbage kimchi during fermentation at 4$^{\circ}C$ and 16$^{\circ}C$ . These results were compared with those of chemical analyses of kimchi juice and sensory evaluation for kimchi. Chemiral analyses and sensory evaluation showed that the kimchi has reached pH 4.3, the pH value under an optimum ripening period, after 3-days fermentation at 16$^{\circ}C$ with almost the highest contents of vitamin C and carotenoids as well as desirable sour taste and texture. At 4$^{\circ}C$ the kimchi was unripened after 6-days fermentation. At 16$^{\circ}C$, $L^{*}$ value of kimchi juice did not show any significant change during fermentation periods. However, $a^{*}$ value increased until day 4$^{\circ}C$ and thereafter decreased sharply. $b^{*}$ value increased until day 3 and then showed no change. High correlations were seen between volume of kimchi juice, pH, total acidity and $L^{*}$or $b^{*}$ value, and between carotenoid content and $a^{*}$ value, respectively. It was desirable to use color $a^{*}$ or $b^{*}$ value of kimchi juice to evaluate the quality of kimchi. The kimchi was under an over-ripening period when $a^{*}$ value was equal to or lower than the initial value, or when $b^{*}$ value was almost constant. Predicting an optimum ripening period was possible by using a proportional value of $a^{*/}$ $b^{*}$ , i.e., unripening period, 1 $\geq$ and near 1 ; optimum ripening period, near 0.8 ; over-ripening period, < 0.8.eriod, < 0.8.d, < 0.8.

  • This study summarizes our findings on the effect of pine needle powder and water extract on the quality characteristics of wet noodle and the changes of microbial count during storage. The lightness of wet noodles was significantly decreased with increasing amounts of PN powder and water extract added in the noodles(p<.001), whereas the redness and yellowness of the noodles were significantly increased(p<.001). Texture evaluation showed that springiness was the highest in the noodle prepared with 5% PN extract, whereas brittleness was the lowest in 1% PN extract. At the beginning period of storage, there were significant differences of microbial cell count in PCA and PDA among the samples, but a significant decreasing was observed after 6 days. In the relationship between sensory and mechanical properties, a negative correlation was observed between color and sleekness, while there was a positive correlation with redness and yellowness. Sensory evaluation showed that odor, taste, texture and overall acceptability were the best in noodles processed with 3% PN extract.

  • The gastric cancer takes the great part of the cancer occurrence and the mortality from cancer in Korea, and the early detection of gastric cancer is very important in the treatment and convalescence. This paper. for the early detection of gastric cancer, Proposes the analysis system of endoscopic image of the stomach that detects the abnormal region by using the change of color in the image and provides the surface tissue information to the detector. While the advanced inflammation and the cancer may be easily detected, the early inflammation and the cancer have a difficulty in detection and require the more attention lot detection. This paper, at first, converts the endoscopic image to the Image of IHb(Index of Hemoglobin) model and removes noises incurred by illumination, and next, automatically detects the regions suspected as cancer and provides the related information to the detector, or provides the surface tissue information for the regions appointed by the detector. This paper does not intend to provide the final diagnosis of the detected abnormal regions as gastric cancer, but provides the supplementary mean that reduces the load and mistaken diagnosis of the detector by automatically detecting the abnormal regions being not easily detected by human eyes and providing the additional information for the diagnosis. The experiments using practical endoscopic images for performance evaluation showed that the proposed system is effective in the analysis of endoscopic image of the stomach.

  • The purpose of study was to improve the storage time of breads with spices. The quality of breads with garlic, ginger and cinnamon powder containing 1 % concentration were investigated using sensory and mechanical evaluation. For 14 days, total microbial count and chemical properties were analyzed at 18$^{\circ}C$. The result of sensory evaluation was not significantly different between control and breads with spices powder. But breads with spices powder were significantly higher than control in texture and acceptability. Especially, bread with cinnamon powder was most favorable in acceptability. The result of total microbial count showed that breads with spices powder were reduced with storing time passed and bread with cinnamon powder was most reduced in breads with spices powder. ks storing time passed, moisture contents and pH range were decreased and L, a and b value were decreased in all breads. Hardness, gumminess and brittleness of torture analysis were increased as storing time passed, but springiness and cohesiveness were decreased. A negative correlation was observed between the sensory and mechanical properties in general. Sensory Properties of springiness and swelling were positively correlated with the acceptability. In the analysis of correlation between the chemical and mechanical properties showed that lightness of mechanical properties had positive correlation with pH range and moisture contents. Moisture contents of chemical properties had negative correlation with hardness, but had positive correlation with cohesiveness of mechanical properties.

  • Paraquat is an effective and widely used herbicide, but it is also very toxic to humans. It is well-known that urine paraquat concentration is one of the most important prognostic indicator for paraquat-poisoning. Quantitative analysis of paraquat, however, are not generally used in clinical laboratories. In this work, a new test strip to detect paraquat concentration using sodium dithionite in urine was developed. Using these second-derivative method, the test strip prepared in $0.5{\%}$ borate buffer (pH 8.0), 0.25 M $Na_2S_2O_4,\0.1~0.8{\%}$ PVP, and $1{\%}$ decanol showed not only better color reaction but also an excellent application possibility to be used in automatic analyzer.

  • Mulberry leaves noodles were prepared with composite flour by the addition of various levels of mulberry leaves powder of 100 mesh particle site. The characteristics of cooked noodle including color, texture, cooking properties were measured, and sensory evaluation was performed. The L and a values of cooked noodle decreased as more wheat flour was substiruted with mulberry leaves powder. And the b value of noodle containing mulberry leaves powder was higher than control, but b value did not increase as the ratio of powder increased. The increase in cooking weight and volume was greater with cooked noodles of higher content of mulberry leaves powder. The turbidity of soup and eluted solid content increased as the content of powder increased, indicating higher cooking loss. There was not much difference in hardness among cooked noodles, but cohesiveness and springiness decreased as the ratio of mulberry leaves powder increased, while adhesiveness increased. The results of sensory evaluation showed that cooked noodles containing 4% and 6% mulberry leaves powder were acceptable as much as wheat four noodle in terms of color, texture, taste and flavor. But the overall acceptability of mulberry leaves noodle was lower than wheat now noodle.
