In this study, we have performed some experimental works on the effects of variation of low, middle and high turbidity for understanding of optical characteristics which is very important factor for the turbidity measurement. The various output frequencies were obtained by the experimental apparatus which consist of detectors, a light source, a frequency counter and so on. From the result of analysis of these frequencies, Firstly, The difference of signal value for each degrees of low turbidity was the smallest of three scopes around the Nephelometric position. Second, the characteristics of each degrees of middle turbidity was proved that signal values of all degrees were larger those of low turbidity but the difference of each signal value of the forward direction was smaller than that of the backward direction. Third, the characteristics of each degrees of high turbidity was proved that though similar to the characteristics of middle turbidity, each signal value of all degrees was larger and the difference of each signal value of all degrees was smaller than those of low and middle turbidity

Objective: This study was to provide a standard for the evaluation of The Korean version of Adolescent/Adult Sensory Profile(K-ASP) for University students and to investigate the difference of the subjective sense recognition regarding the characteristics of sensory processing. Method: The subjects consisted of 84 University students. A researcher examined subjective sense recognition and K-ASP for subjects. Visual Analog Scale used to evaluate subjective sense recognition and K-ASP was utilized to evaluate the characteristics of sensory processing. Results: 1. The average scores and standard deviation of K-ASP were $32.93{\pm}7.88$ for low registration group, $39.39{\pm}6.55$ for sensory seeking group, $38.94{\pm}9.13$ for sensory sensitivity group, and $34.24{\pm}7.85$ for sensory avoiding group. 2. The correlation between the total score on an each quadrant and the subjective sense recognition are -.27 for low registration group, .11 for sensory seeking group, .09 for sensory sensitivity group and .12 for sensory avoiding group. It showed the statistically significant correlation between the total score of low registration and the subjective sense recognition group(p<.05). 3. The average scores and standard deviation of the subjective sense recognition were $5.22{\pm}1.56$ for high threshold and $7.28{\pm}1.70$ for low threshold. The subjective sense recognition according to the characteristics of sensory processing showed the statistically significant difference. Conclusions: This study supports the theory that there is the difference of sensory recognition according to each individual and we found that people with difficulties of sensory processing acknowledge their characteristics of sensory processing well.

In order to investigate the possibility of lwo fat meat products, beef patties were prepared with gums such as carrageenan, methyl cellulose, and xanthangum. The quality characteristics of beef patties were examined. Moisture contents of raw and cooked patties of control were lower than those of patties containing gums, and fat content was higher than those of containing gums. There was no significant difference in the protein contents of patties. In case of L-value(lightness) of raw patty, the control was higher than those patties containing gums. a-(redness) and b-value(yellowness) among patties were not significantly different. Cooking yield, fat retention, and water holding capacity of beef patties containing gums were higher than control beef patty, but salt soluble protein and gel strength were not significantly different. Significant difference did not exist among beef patties in hardness, but the chewiness and gumminess of patties containing gums were higher than control. In case of sensory evaluation, there was no significant difference among patties in aroma and palatability. Texture of control was higher than patties containing gums, and juiciness of control was higher than patties containing carrageenan.

As the blueberry content in batter increased, the pH of batter decreased According to the measured results about specific gravity of muffin batter, there was no significant difference among each batter including 0% 10% and 15% blueberry, while each 15% 20% and 30% dough showed significant difference (p<0.001). According to the results about general quality characteristics of muffins such as volume, weight and specific gravity, as the content of blueberry juice increased, the volume decreased. In terms of measuring specific volume, it decreased as the added amount increased According to measuring the chromaticity of muffins, as the blueberry content increased in the muffins, brightness and yellowness decreased while redness increased In terms of the measurement of texture, the hardness showed significant difference among all sample muffins (p<0.001). Significant difference was not shown in the springiness (p<0.05). As the amount of blueberry juice increased, the chewiness of the muffins was grown. The result showed a significant difference between samples in the adhesiveness (p<0.001). As the amount of blueberry juice increased, the adhesiveness of muffins also increased In the organoleptic test, a significant difference was shown in the color among all sample (p<0.001). The blueberry juice content of 20% showed highest figures with $7.12{\pm}0.67$. In terms of flavor, the content of 20% also showed highest figures among all samples with $7.16{\pm}0.62$ (p<0.001). Concerning the taste all samples showed a significant difference while 20% content did the highest figure. In the overall acceptability the content of 10% showed the lowest figure while 20% displayed the highest figure with 7.16. According to the quality characteristics of blueberry muffins, the best blueberry juice content would be 20% content group.
