This study was conducted to investigate rheological and sensory characteristics of Sulgidduk added with pine mushroom powder. The moisture content of the Sulgidduk ranged from 34.79 to 36.93%. Increasing the amount of pine mushroom powder in the Sulgidduk tended to decrease the pH value, but to increase the $brix^{\circ}$ value. Increasing the amount of pine mushroom powder in the Sulgidduk tended to decrease the lightness(L) in Hunter color value, but to increase the redness(a) and yellowness(b). For the textural characteristics, the addition of pine mushroom powder decreased the adhesiveness and springiness. In sensory evaluation, the addition of 3% pine mushroom powder had the best score in appearance, odor, taste and overall preference. Therefore, this results suggest that adding 3% pine mushroom powder would be feasible for making pine mushroom Sulgidduk.

To develop a value-added product from individually quick-frozen oysters Crassostrea gigas (IQFO), we prepared a retort pouched oyster soup (RPOS) from IQFOs and characterized its processing conditions and quality metrics. We found that the most appropriate manufacturing process for the RPOS consisted of half-thawing and washing raw IQF oysters, blanching, adding them to the retort pouch along with other ingredients (base soup stock, IQF oyster extract, radish, bean sprouts, garlic, and red pepper), sealing, retort sterilization ($120^{\circ}$, F0-value 10 min.), cooling, and packaging inspection. The moisture, crude protein, pH and salinity of the RPOS were 91.0%, 2.8%, 6.20 and 0.9%, respectively. The total amino acid content of the RPOS was 2,163.8 mg/100 g, and the main amino acids were glutamic acid, aspartic acid, leucine, proline, lysine and arginine. The primary inorganic ions were Na, K, S and Zn. In taste compounds, total free amino acid content was 313.4 mg/100 g, and the main free amino acids were glutamic acid, taurine, proline, hydroxyproline, aspartic acid, glycine, alanine, valine, lysine and arginine. This RPOS has good storage stability and organoleptic qualities compared with commercial retort pouched shellfish soup, and is suitable for commercialization as a value-added instant seafood soup.

Effects of Prunus mume byproduct (PLB), obtained after manufacture of Prunus mume liquer, on quality characteristics of bread were investigated. The pH of dough and bread decreased but titratable acidity increased by addition of 10% or 20% PLB. The volume of dough during fermentation and the baking loss of bread containing PLB were smaller than those of the dough and bread without PLB. The weight of bread increased but the volume decreased by addition of PLB. L (lightness) value increased and a (redness) value decreased in the surface of bread containing PLB. b (yellowness) value did not show difference between treatments. The internal color of bread containing PLB decreased in L and a value but increased in b value. The hardness and strength of bread decreased with 10% PLB but increased with 20% PLB compared to control. Cohesiveness and springiness of bread increased with 10% or 20% PLB, but did not show significant difference between concentrations. As results of sensory evaluation, taste and flavor of the bread containing 10% PLB increased significantly compared to control. The sensory quality of bread with 20% PLB decreased significantly. The strength, springiness, and hardness of bread with 20% PLB were higher than those of control. The taste, flavor, color, and overall acceptability of bread with 10% PLB were better than those of control. No molds were found in breads with 20% PLB and 20% PLB powder during storage for 1 week at room temperature.

We investigated the characteristics of breads containing Schizandra chinensis Baillon (SCB) added as whole powder, as a powder prepared from juice, and as a concentrate prepared from a 95% (v/v) ethanolic fruit extract, added to wheat flour at 0.5% (w/w). Addition of any form of SCB lowered the pH and increased the titratable acidity in both doughs and breads compared with control values, and the whole and juice powders were more effective in this respect than was the concentrated ethanolic extract. Dough volume during fermentation was increased by addition of whole powder and concentrated ethanolic extract, but no baking loss was evident upon addition of any form of SCB. Regarding the bread surface, the lightness (L) value was increased by addition of juice powder and concentrated ethanolic extract, but neither the redness(a) and nor the yellowness (b) values showed such increases. Internal color measurements showed increased '-a-' value upon addition of any form of SCB, and increased '-b-' value when concentrated ethanolic extract was used, however, there were no significant changes in L value. Sensory evaluation of taste, flavor, color, and overall acceptability showed that bread prepared using whole powder was more acceptable than were the other forms.

With the development of cloud computing, more and more Web services are deployed on geo-distributed datacenters and are offered to cloud users all over the world. Through service composition technologies, these independent fine-grain services can be integrated to value-added coarse-grain services. During the composition, a number of Web services may provide the same function but differ in performance. In addition, the distribution of cloud datacenters presents a geographically dispersive manner, which elevates the impact of the network on the QoS of composite services. So it is important to select an optimal composition path in terms of QoS when many functionally equivalent services are available. To achieve this objective, we first present a graph model that takes both QoS of Web services and QoS of network into consideration. Then, a novel approach aiming at selecting the optimal composition path that fulfills the user's end-to-end QoS requirements is provided. We evaluate our approach through simulation and compare our method with existing solutions. Results show that our approach significantly outperforms existing solutions in terms of optimality and scalability.

The quality properties of Jeung-pyun made with soybean protein isolate(SPI) were investigated. The SPI Jeung-pyun was manufactured using 3% whole protein, 7S protein or 11S protein(w/w). The redness values (a-values) of the Jeung-pyun were negative and the yellowness(b-value) of the control group was significantly lower compared to the other samples. The textural characteristics of the Jeung-pyun were influenced by the additions of SPI. The Jeung-pyuns containing soybean flour, whole protein, 7S and 11S protein had increases in springiness, but decreases in cohesiveness. In the sensory evaluation, overall desirability, sweetness, and moistness were highest in the whole protein group. The control group showed the highest scores for hardness and toughness, and the scores for after-taste and adhesiveness were the highest in the samples made with soybean flour. The 7S and 11S additions showed high scores in terms of color and springiness. In the analyses for consumer acceptance and sensory quality intensity, the whole protein addition had significantly higher scores for general acceptability and the Makgeolli flavor. Hardness was highest for the control group and the Makgeolli flavor was strongest with the soybean flour addition.

In this study, sponge cakes were prepared with replacement of 1, 3, and 5% spergularia marina griseb powder. The specific gravity tended to increase as the ratio of spergularia marina griseb powder increased. The control group had higher moisture content, volume, and specific volume than the spergularia marina griseb powder samples. As the amounts of spergularia marina griseb powder increased, L and b value increased. In terms of textural characteristics, Sponge cake levels of hardness, springiness, cohesiveness, chewiness and brittleness increased as the amount of spergularia marina griseb powder additive increased. In the sensory evaluation, overall acceptability of 3% spergularia marina griseb powder was the highest. Based on the above results, sponge cake, made by addition of 3% spergularia marina griseb could be helpful in improving physical quality as well as taste enhanc the functionality of the product.
