$Ca^{++}$ content and histochemical changes during processing Mooks prepared with sea mustard (Undaria pinnatifida) and sea tangle (Laminaria japonica) were studied. $Ca^{++}$ content of sea mustard Mook during gelation in $CaCl_2$ solution was not only increased fast, but also decreased fast during soaking in distilled water as comparing with that of sea tangle Mook. Both solubilization of the seaweeds by 1 % $K_2HPO_4$ and filtration of solubilized seaweed were decreased the extruding amount of $Ca^{++}$ from Mooks during soaking. The cell walls in sea mustard were likely irregular and ling, but those in sea tangle were regular and round shape. alginic acid was mainly occurred around cell walls. The alginic acid was gradually solubilized depending on heating and alkali treatment. Thus, the fillament cells in sea tangle were cut finely during processing Mook, while those in sea mustard were remained tolerably.

The physical properties and sensory characteristics of acorn starch gels (Dotori Mook), which were gamma-irradiated up to 3 kGy, were evaluated during storage at $4^{\circ}C$. Even at the dose of 2 kGy, the gamma irradiation decreased total bacteria in the Dotori Mook during 5 days of storage, to lower than the detection limit $(10^2CFU/g)$. The hardness of the control sample increased according to the days of storage, while the gamma irradiated samples had decreased hardness according to the irradiation dose. The sample irradiated at 3 kGy maintained the same hardness as the control at day 0 of storage. Irradiation did not affect the Hunter color values. No significant differences were observed in off-odor, color, springiness, and overall acceptability (p<0.05) at the irradiation dose of 2 kGy. It can be concluded that the irradiation of Dotori Mook, up to 2 kGy, does not affect the quality of the Mook during storage, with regard to texture and sensory characteristics. Moreover, the irradiated Mook was superior in maintaining hardness and had prolonged shelf-life time by sanitation.

The optimum conditions for springiness of polymannuronate acorn mook, in which polymannuronate was added to acorn powder, was investigated by the response-surface method(RSM). The fractional factorial design with three variables, i.e. polymannuronate addition, water addition and boiling time, and with three levels revealed that the range of acorn springiness was $0.804{\sim}0.987$. The governing equation was also partially differentiated for boiling time, showing that the optimum manufacturing condition for $90^{\circ}C$ is addition of 2% polymannuronate, addition of 120 mL of water, and 60 minutes of boiling time.

This study evaluate the quality characteristics and antioxidative properties of acorn starch mook containing spirulina (0%, 0.5%, 1%, 1.5%) and soy protein (3%). The pH of acorn starch mook containing the spirulina and soy protein decreased with increasing amount of spirulina decrease in pH means an increase in acidity. In addition, the moisture content was 87%. The lightness of acorn starch mook containing spirulina and soy protein decreased with increasing amount of spirulina and soy protein. The L and a values of the Hunter color system were decreased significantly increasing spirulina content, and the b value increased. In contrast, with increasing spirulina and soy protein content, the L and a increased significantly and the b value. Texture analysis revealed higher hardness and springiness of acorn starch mook containing spirulina than the control. The total phenol content was highest in the acorn starch mook containing 1.5% spirulina and 3% soy protein. The antioxidant activities of the acorn starch mook containing spirulina and soy protein increased with increasing amount of spirulina and soy protein. The $IC_{50}$ value of 1.5% spirulina and 3% soy protein was 166.2 mg/mL for DPPH. The results of the sensory test were best in the acorn starch mook containing 1% spirulina.

Studies were carried out to investigate formation of Mook and its physical properties as well as the effects of amylose and amylopectin on the texture of Mook which were made from cowpea, mung bean, acorn, buckwheat, kidney bean, potato, rice, corn and wheat starches. Texture parameters of 10% starch gels were significantly different depending on the kind of starches. However, there were no significant differences in those of gels of starches commonly used for the preparation of mook. It was appeared that gel indices of cowpea, mung bean, acorn and buckwheat starch gels were in the range of 2.11-2.37, elastic limits were more than 0.60, gel strength coefficients were in the range of 700-1400 and brittlnesses were 0.23-0.62. It was also appeared that gel index and elastic limit were affected by amylopectin and gel strength coefficient and brittleness, by amylose, and that these two fractions were not able to form gel like Mook unless they were combined with proper proportion. Effect of addition of amylose from cereal and potato starches to cowpea starch or cowpea amylopectin were different from that of cowpea amylose. When cereal starches were supplemented by cowpea starches, gel strength coefficients and brittlenesses of their gels were increased, but gel indices and elastic limits were not changed. However, potato starch gel was improved to be similar to Mook with increasing of gel strength coefficient and appearance of brittleness by addition of cowpea amylose.

This study was to examine the characteristics in the texture of acorn Mooks (acorn starch jelly) with different conditions to prepare acorn starch. By texture profile analysis, hardness and chewiness with 50% deformation were increased with increasing soaking days. Hardness of acorn Mook, measured by texture analyzer, showed significantly difference between the samples, and was closely related to the content of non-starchy substances and their intrinsic viscosity. The observation of microstructure through a scanning electron microscope (SEM) showed that acorn Mook showed finer and more fibrous structure than control(0-0), sample without soaking of acorn and sediments. Sensory characteristics of acorn Mook were affected by soaking treatment. The result of acceptance test on acorn Mooks indicated that the color and hardness increased with the increase of soaking days of acorn nuts and soaking times of sediments. There was a little difference between the samples in astringency taste. Their overall acceptability also increased except for 4-2 sample (i.e., soaking of acorn, 4 days; soaking of sediments, 2 times) and 4-3 sample (i.e., soaking of acorn nuts, 4 days; soaking of sediments, 3 times). As the results, the color, light brown, and the taste, a little astringency with consistency, were important factors of acorn Mook.

The important legumes in Korea are mungbean, red bean, kidney bean and cowpea. Mungbean has traditionally been used for mook (jelly-like starch gel) preparation. Cowpea has recently been utillized for substitution of mungbean. The major use of sediment of red bean is for the sweet paste. The studies related to legume starches and flours (air-dried sediment) in Korea are concentrated on the understanding of the properties of mook. The structure of starch, gelatinization and gelling properties of legume starches and flours are reviewed with emphasis of Korean literatures.

On-Line Lectures are becoming more common due to the MOOK service and the expansion of national policy in Korea. Especially, It is being changed to new remote mixed style from traditional lecture in universities. We propose and implement a remote contents making tool with audio synchronization function based on more with less resources. To implement our proposed algorithm, we design an interactive interface to assign multiple cutting intervals and convert an input video to print a new result. In experimental, we can confirm our algorithm works properly with average performance value 9.3% cpu share ratio and 87mega byte ram usage(CPU 2.60GHz, 820*600 Area).
