  • This study was carried out in order to optimize the manufacturing condition of fried garlic flakes as well as to investigate the physicochemical properties of the flakes. Fried garlic flake samples were prepared as follows: garlic was sliced by a thickness of 1.5 mm, 2.0 mm, 2.5 mm, which were measured by a thickness gage. The samples were fried in vegetable oil under different temperatures of $140{\sim}150^{\circ}C$, $160{\sim}170^{\circ}C$ and $180{\sim}185^{\circ}C$. The compression strength depending on the height (h) was measured in order to find the thickness effect by the rheometer (force control: 50 N, h: 3.25 mm). Moreover, the sample with 1.5 mm thickness showed crisp phenomena of the split compared with the crush shape of the 2.0 mm and 2.5 mm thick samples. The result of strength for time dependence showed a sample with a thickness of 1.5 mm, which was measured 5~9 times more than the 2.0 mm and 2.5 mm thick samples. We thought the reason that the 1.5 mm sample had less response power equivalent to compression force than the other samples. Alliin has been found to affect the immune responses in the blood, it is a derivative of the amino acid cysteine and is also quite heat stable. The LC system with a UV detection at 210 nm consists of a separation on a Zorbax TMS column and isocratic elution with water and ACN as a mobile phase. The alliin contents of raw and fried garlic flake under $140{\sim}150^{\circ}C$, $160{\sim}170^{\circ}C$ and $180{\sim}185^{\circ}C$ were 18.10 mg/mL, 14.0 mg/mL, 11.6 mg/mL and 11.1 mg/mL, respectively. The decrement of alliin content under different temperature was a small quantity hence, we confirmed that the increasing manufacturing temperature was not affected by the alliin content. Examining for the particle structure of fried garlic flakes by a polarization microscope, the color of the sample treated at $160{\sim}170^{\circ}C$ was pure yellow. Furder, the fiber shaped particle, which has an effect on the tough texture, almost did not appear compared to the different temperature conditions. Finally, the sensory test for the preference of fried garlic flake under different conditions was carried out and the scores for various sensory characteristics were surveyed. According to the physicochemical measurements and sensory evaluation, we confirmed that the optimum manufacturing condition of fried garlic flake was 1.5 mm thick at a temperature of $160{\sim}170^{\circ}C$.

  • To develop a low-temperature and long-term fermented Baechu kimchi, kimchi was prepared according to a recipe of specific ratio with major and minor ingredients and adjusted its final salinity to 3.7%. Baechu kimchi fermented at $15{\pm}1^{\circ}C$ 24 hours and transferred them into in a refrigerator only for kimchi, and then continued to ferment at $-1{\pm}1^{\circ}C$ for 30 weeks to make a low-temperature and long-term fermented kimchi. The initial cutting force of 8.45kgf dropped gradually and reached to 5.19kgf after 30 weeks of fermentation. In compression force the gumminess, hardness and chewiness of Baechu kimchi showed a great decrease during the fermentation, but the springiness and adhesiveness increased in slight. Correlation coefficient between the chewiness and gumminess was the highest(r=0.879). In spite of sensory evaluation scores of the appearance and texture were the highest on 0 day of fermentation, the saltiness was evaluated the worst to eat. Scores for sourness and carbonated flavor were the best during 18 to 22 weeks of fermentation, and overall acceptability was the best after 14 weeks of fermentation. Very high correlation coefficients were revealed between the sourness and carbonated flavor(r=0.813) and between the sourness and off-flavor(r=0.805). According to these results we concluded that the best low-temperature and long-term fermented Baechu kimchi prepared with 3.7% salinity and fermented at $15{\pm}1^{\circ}C$ for 24 hours and then transferred into a kimchi refrigerator at $-1{\pm}1^{\circ}C$, and completed the fermentation for 18 weeks.

  • Safflower Yangengs were prepared with composite dried powder of small red bean(Phaseolus radiatus L.) containing various ratios of safflower(Carthamus tinctorius L.) seed powder sifted through 20, 35, 45 and 60 mesh size and kinds of mixed water, their cooking characteristics were evaluated. Water content and water activity of cooked products were increased as the content and sieve mesh number of safflower seed powder increasing from 5%, 20 mesh to 20%, 60mesh, respectively. Color values of yangeng were increased in green tea extract mixed water. Rheological properties of yangengs were measured by compression test with texture analyzer, as results, hardness and fracturability increased that were shown in high content and high mesh number sifted safflower seed powder, but adhesiveness and springiness decreased, respectively. From the sensory evaluation test for yangeng, sensory scores were good scores in more mesh number sifted powder addition, especially overall acceptance, texture and fracturability. The 45mesh and 15% powder added yangeng was noted as having high sensory scores and preferable acceptability in sensory evaluation.

  • An instrumental analysis of Sanyakbyung was carried out along with sensory evaluation to find out how its quality characteristics changed by the addition of glutinous rice flour(0%, 10%, 20%, 30%, 40% and 50%). The moisture content of Sanyakbyung decreased in proportion to the increment of glutinous rice flour. In terms of color, L-value increased depending on the increment of glutinous rice whereas a-value and b-value showed a decrease. This could be accounted for by two factors: one is that the protein contained in yam flour contributed to black coloring and the other is that the color of yam flour itself contributed ostensively to the tint of blackish coloring, and also to the tint of yellow and red coloring. ln the two bite compression test, the hardness, gumminess, chewiness, and cohesiveness of Sanyakbyung decreased depending on the increment of glutinous rice flour. The springiness did not show any significant variation among the samples. That is, the more yam flour was added, the more cohesive and gummy Sanyakbyung was produced. There were significant differences(p<0.05) in the sensory characteristics of the samples in which Sanyakbyung with 10% glutinous rice flour was most preferred in color, those with 20% in flavor, and those with 40% in taste. Adhesiveness and consistency in the palate responses also showed significant differences among samples in which the sample with 40% glutinous rice flour was most favored in consistency. When the content of yam increased, the gumminess also increased. Generally, Sanyakbyung with soft but less gummy texture was preferred to strong gummy one which was easily stuck to teeth. In the overall acceptance, Sanyakbyung with 40% glutinous rice four was most preferred.

  • The standard map for polyerystalline $YBa_2Cu_3O_7$-X was construeted and indexed from pressed tape sintered bulk and compressed bulk samples were drawn by the [001-110-110] stereographie quadrant map and by the ECPs from individual grains of the speeimens. The relationship between the (001) texture development and critical current density (Jc) for various samples was discussed. An (001) orintation was preferred in the pressed tape thickness was decreased. and in the compressed bulk as the compression strain was increaesed.The (001) orientation made a signifieant in crease on Jc. We conclded that an ECP technique was very useful for the analysis of the orientation distribution in small-sized $YBa_2Cu_3O_7$-X specimens such as superonducting tapes or thin films.

  • This paper is concerned with the mesh segmentation problem that can be applied to diverse applications such as texture mapping, simplification, morphing, compression, and shape matching for 3D mesh models. The mesh segmentation is the process of dividing a given mesh into the disjoint set of sub-meshes. We propose a method for segmenting meshes by simultaneously reflecting global and local geometric characteristics of the meshes. First, we extract sharp vertices over mesh vertices by interpreting the curvatures and convexity of a given mesh, which are respectively contained in the local and global geometric characteristics of the mesh. Next, we partition the sharp vertices into the $\kappa$ number of clusters by adopting the $\kappa$-means clustering method [29] based on the Euclidean distances between all pairs of the sharp vertices. Other vertices excluding the sharp vertices are merged into the nearest clusters by Euclidean distances. Also we implement the proposed method and visualize its experimental results on several 3D mesh models.

  • Meat emulsions containing 0, 15, 30 and 45% of soy protein isolate(SPI), Na-caseinate(Na-CN) and their mixtures were prepared in order to determine the effect of these non-meat proteins on the physical properties and their sensory quality in emulsion type sausage. It was found that SPI was better fat stabilizer and better binder than Na-CN. The mixtures of SPI and Na-CN didn't exert any significant effect on emulsion stability. From the texture profile analysis by using Instron two-cycle compression tests, decrease in the substitution levels and increase in the ratio of SPI/Na-CN resulted in a significant increase in the textural values of hardness, adhesiveness, gumminess, chewiness. The finished products showed that the substituted product for 15 % meat protein had higher textural values than the unsubstituted product. The sensory quality evaluated for the final products showed no significant difference between the SPI substituted product for 15 % meat protein and the unsubstituted product. However, all of the substituted products for 15 % meat protein and some of those for 30 % substitution with SPI and 67 % SPI received higher scores than average.

  • Video objects of interest play an important role in representing the video content and are useful for improving the performance of video retrieval and compression. The objects of interest may be a main object in describing contents of a video shot or a core object that a video producer wants to represent in the video shot. We know that any object attracting one's eye much in the video shot may not be an object of interest and a non-moving object may be an object of interest as well as a moving one. However it is not easy to define an object of interest clearly, because procedural description of human interest is difficult. In this paper, a set of four filtering conditions for extracting moving objects of interest is suggested, which is defined by considering variation of location, size, and moving pattern of moving objects in a video shot. Non-moving objects of interest are also defined as another set of four extracting conditions that are related to saliency of color/texture, location, size, and occurrence frequency of static objects in a video shot. On a test with 50 video shots, the segmentation method based on the two sets of conditions could extract the moving and non-moving objects of interest chosen manually on accuracy of 84%.

  • The effects of Backryeoncho (Opuntia ficus-indica var. saboten) powder addition (0, 0.4, 0.8, and 1.2%) on the pH, titratable acidity, lactic acid contents, microbial contents, texture, and sensory evaluation of cabbage Kimchi, stored at $10^{\circ}C$ for 36 days were studied to establish an optimum recipe. Upon addition of Backryeoncho powder, pH was higher than that of Kimchi without powder after 36 days of fermentation. The titratable acidity was increased by the addition of Backryeoncho powder, and 0.4% powder added Kimchi showed the slowest changing level. During the fermentation period, the degree of salinity decreased with the addition of powder from 2.52 to 2.19 to 2.10. The a value was higher in Kimchi with added Backryeoncho powder in a dose-dependent manner compared with control Kimchi. The cutting force and compression force were higher during the fermentation period, and especially addition of 0.4% powder showed the highest value of hardness. The addition of powder slowed growth of lactic acid bacteria as compared with the control samples. In the sensory evaluation of overall taste, 0.4% addition of powder improved the quality of Kimchi. Therefore, addition of 0.4% Backryeoncho powder apears to be an acceptable approach to enhance the quality of Kimchi without reducing acceptability.
