In this study, kiwi fruit, which has various medical actions and excellent functionality, was used together with gruels for comparison and analysis of to compare and analyze the changes in physico-chemical quality of a kiwi fruit-gruel according to the amount of kiwi concentrate added to the gruel. Analysis on the sensual quality of kiwi fruit-gruel spread was done to indicate to it was executed to find out the merchandising potential of the preparation and to provide basic data for gruel commercialization. Increasing content of kiwi concentrate decreased the solid content and pH of kiwi fruit, and increased sweetness and viscosity. Significant changes in chromaticity to L(lightness) and a(redness), texture qualities of hardness and cohesiveness, gumminess, springiness, color, flavor, sourness, and sweetness were evident with increasing kiwi concentrate. Concerning overall acceptability and sensory evaluation, 20% softness samples were most preferred. The findings may lead to enhanced medical/nutritional activity and functionality of kiwi fruit-supplemented gruel. The more the kiwi concentrate was added to the gruel, solid content and pH of the kiwi fruit-grue decreased. The sweetness and viscosity of kiwi fruit-gruel increased. For chromaticity to L(lightness) and a(redness) of the gruel decreased and showed significant difference between sample groups. For texture, there were significant changes shown for hardness and cohesiveness the amount of kiwi concentrate added was different, increased There was a significant change between samples for gumminess. As for springiness, there was a significant change between samples. There were significant difference between each sample for color, flavor, sourness, sweetness. For softness, overall-acceptability and sensory evalution 20% group was most preferred based on this study, from the physico-chemical and sensual perspective, 20% group is highly recommended for adding kiwi concentrate into gruel. In conclusion, this study is meaningful as it enhanced the functionality and quality of a gruel by combining kiwi fruit with various medical action and excellent functionality, with Kiwi Fruit and presented a basic material for creating a kiwi concentrate combined gruels.

Mostly mine support(Rock bolt and Support) which is currently general for reinforcements of a large scale tunnel is applied, Some executing a reinforcement to Poor ground by cast-in-place shotcrete. However On domestic mine conditions that couldn't having every time after mine tunnel excavation, it couldn't ensure the field batch plant which is a fixed in an issue of economies and site security, constructing it by supply gets from shotcrete materials combined in neighborhood ready mixed concrete manufacturing plants. carried shotcrete in ready mixed concrete manufacturing plants as migration length and time are falling off in quality. But, it is difficult for construction quality control By quality control arbitrariness absence at on-scene. In the present study, carry out Laboratory Test by kinds and percentages of accelerating agent for evalution of Mechanical Property and Durability of Shotcrete.

Jeung-pyun added to mulberry leaves powder was tested to prove in inorganic ingredients, physical function, chromaticity and rheometer. For cake, mulberry leaves powder were added to rice flour in the ratio of 0%, 1%, 2%, and 3% respectively. In inorganic ingredients test, the amounts of calcium, magnesium and potassium were increased according to adding levels of mulberry leaves powder. But the amounts of iron, copper and zinc, were not correlated with it. Calcium, magnesium and potassium are anti-hypertension inorganic substances. Thus, it is considered that food with plenty amountsz of inorganic ingredients is an effective diet for the patients who suffer from cardiovascular disease. In physical evalution test, the ratio of mulberry leaves powder was not correlated with the appearance of Jeung-pyun. The value of color decreased as the ratio of mulberry leaves powder increases. In texture, Jeung-pyun. The value of color decreased as the ratio of mulberry leaves power increase. In texture, Jeung-pyun added with 2% mulberry leaves powder had the highest value. In moisture, as the level of mulberry leaves powder was increased, the value was decreased. In rheometer test, Jeung-pyun 0% mulberry leaves powder had the highest value in hardness. While the ratio of mulberry leaves powder was not correlated with cohesiveness. Jeung-pyun added to 1% mulberry leaves powder had the highest value. In gummines and brittleness, 0% Jeung-pyun had the highest value, but the ratio was not correlate with cohesiveness.

This study attempted to determine the effect of various thawing methods and storage periods on the quality of froen cooked rice. Frozen cooked rice was thawed at four different methods, such as pressure cooking, conventional cooking, microwave heating and thawing at room temperature after 10 days, 30days and 90 days frozen storage. We conducted a physico-chemical analysis (moisture content, dehydration rates, degree of gelatinization, color value and texture) and sensory evalution on the frozen-thawed cooked rice. The study showed that there were no significant differences on the quality characteristics of frozen-thawed cooked rice during the storage period of 90 days. However, the thawing method of pressure cooking caused high moisture content, rapid dehydration rates, and a high degree of gelatinization on the cooked rice. Thus, the desirabililty for the rice diminished becaused of the excess moisture content and the change of appearance and testure in the rice due to the high temperature. There were similiar quality characteristics to the cooked rice after forzen-thawing whether by conventional cooking or by microwave heating and just after cooking. Thawing at room temperature also caused a significant decrease in quality characteristics.

Manual grading and sorting of red-ginsengs are inherently unreliable due to its subjective nature. A computerized technique based on optical and geometrical characteristics was studied for the objective quality evalution. Spectral reflectance of three categories of red-ginsengs - "Chunsam", "Chisam", "Yangsam" - were measured and analyzed. Variation of reflectance among parts of a single ginseng was more significant than variation among the quality categories of ginsengs. A PC-based image processing algorithm was developed to extract geometrical features such as length and thickness of body, length and number of roots, position of head and branch point, etc. The algorithm consisted of image segmentation, calculation of Euclidean distance, skeletonization and feature extraction. Performance of the algorithm was evaluated using sample ginseng images and found to be mostly sussessful.

Moisture content was 79.5%, banjhi shoot was 77.8% of the total and the weight was 29.4 g/100 buds in the harvested plant leaves used for manufacturing Okro tea. Okro tea heated at 75$^{\circ}C$ for 30 min showed the best quality among all the treatmants. Chemical components such as total nitrogen, theanine, arginine and chlorophyll were high in the tea treated at 75$^{\circ}C$ for 30 min compare with those of other treatments. The sensory evalution test In terms of appearance shape color and taste showed greater preferences in Okro tea treated at 75$^{\circ}C$ for 30 min than those of other treatments. The results suggested that heat treatment at 75$^{\circ}C$ for 30 min was the best condition for the final rolling process in manufacturing of Okro tea.

LOHAS(Lifestyles Of Health And Sustainability) drinks were prepared by the addition of mulberry leaf powder(MLP) at various levels(0%, 5%, 10% and 20%). Their characteristics of the drinks were examined according to antioxidant activity and sensory evaluation. In the sensory evaluation, there was no significant difference between the control group(0% MLP group) and 5% MLP group for overall quality. For the proximate compositions of the LOHAS drinks, moisture, crude ash, crude protein and crude fat were all increased as the ratio of MLP increased. For the mineral contents, the amounts of calcium and magnesium were increased, but sodium, according to adding levels of MLP.
