This paper is related to an Object VR-based virtual textile wearing system carrying out textile texture mapping based on viewpoint vector estimation and intensity difference map. The proposed system is characterized as capable of virtually wearing a new textile pattern selected by the user to the clothing shape section segmented from multi-view 2D images of clothes model for Object VR(Object Virtual Reality), and three-dimensionally viewing its virtual wearing appearance at multi-view points of the object. Regardless of color or intensity of model clothes, the proposed system is possible to virtually change the textile pattern with holding the properties of the selected clothing shape section, and also to quickly and easily simulate, compare, and select multiple textile pattern combinations for individual styles or entire outfits. The proposed system can provide higher practicality and easy-to-use interface, as it makes real-time processing possible in various digital environment, and creates comparatively natural and realistic virtual wearing styles, and also makes semi-automatic processing possible to reduce the manual works.

Traditional Jeju tofu with a hard texture was manufactured by traditional method with a compounded coagulant. The processing condition for industrial production was optimized by determining soaking of soybean, extraction and heat treatment of soymilk as well as concentration and composition of coagulant. Maximum yield of soymilk was obtained by grinding one part of soaked soybean with eight parts of water, and the soluble solid of soymilk was about 8$^{\circ}$Brix. The free thiol group in soymilk was maximally exposed by heating at 10$0^{\circ}C$ for 2 min. A vacuum cooker for heating soymilk was effective for the improvement of yield and texture properties of tofu. The hardness of traditional Jeju tofu was obtained by increasing pressing time and drying by a fan instead of soaking in cold water. Optimization of a traditional tofu production resulted in the increase of total yield and improvement of quality control. Texture of traditional Jeju tofu prepared in industrial production scale was analyzed by instrumental analysis and sensory evaluation. Traditional Jeju tofu showed higher score in the hardness, roasting taste and overall preference compared with a commercial tofu, showing significant difference in 5% significant level..

This study was conducted to investigate the characteristics of sponge cake quality added with different levels of Schizandra chinensis powder. Schizandra chinensis sponge cake was prepared with different levels of Schizandra chinensis (0, 5, 15, 20%). The proximate composition contents of Schizandra chinensis powder were analyzed as composed of 8.732% moisture, 10.25 crude protein, 8.63 crude lipid, and 1.98 crude ash. Results show that the baking loss rate was decreased with levels of Schizandra chinensis powder added, and the height was decreased as the Schizandra chinensis powder increased. As added ratio of Schizandra chinensis powder increased, L and b values were decreased. In addition, the texture properties result showed that the hardness and cohesiveness of sponge cake increased as the Schizandra chinensis powder added, while springiness decreased. Last, the sensory evaluation showed that the group of 5% Schizandra chinensis powder had the highest preference scores. Therefore, Sponge cake added with 5% Schizandra chinensis powder add gave the better taste and quality to sponge cakes in this study.

The effects of soaking and steaming time on the quality characteristics of Korean rice cake (karedduk) were investigated. As the soaking time increased, the water-binding capacity and rice floor solid content also increased. After 8 to 10 hr soaking, 75.2 to $76.8\%$ of particles were smaller than $40\;{\mu}m$, and 23.2 to $24.8\%$ within the range of 40 to $100\;{\mu}m$. Therefore, an extended soaking time reduced the particle size. Texture is an important characteristic used to differentiate karedduk varieties, and is considered by the consumer as a determinant of the overall quality and preference. The hardness, cohesiveness, gumminess and chewiness of the karedduk structure decreased with increasing steaming time, but the springiness was highest after a 40 min steaming time. The overall texture properties were also more acceptable with 8 and 10 hrs soaking times. The L value of the karedduk decreased with increasing steaming time, but the b value increased. Also, the results of the sensory evaluation showed that an 8 hr soaking time and 40 min steaming time produced more acceptable karedduk in terms of whiteness, texture, springiness, chewiness and overall acceptability.

To improve the sensory quality of sliced raw fish, the effect of cold brine temperature on the texture properties was investigated. Fishes were immersed in cold brine by various condition and killed instantly by spiking at the head. The onset of rigor-mortis was accelerated by decrease of immersion temperature. Also, the time reaching full rigor was shortened remarkably too. However, the rigor index of samples immersed in the cold brine decreased more than that of samples killed instantly. Rigor index was the highest in samples killed instantly, followed by $0^{\circ}C,\;-5^{\circ}C,\;-10^{\circ}C,\;-12.5^{\circ}C,\;-15^{\circ}C\;and\;-20^{\circ}C$ in that order. The breaking strength of samples immersed in the cold brine increased slowly but did not increase through all the conditions in the samples. Breaking strength of all samples immersed in the cold brine decreased significantly after reaching the maximum values (p<0.05). The lactate content of muscle was increased by the decreased brine temperature, however ATP content decreased. Minimum lactate and maximum ATP content in fish muscle showed at $-12.5^{\circ}C$. Those results demonstrate that optimal temperature for improvement of sliced raw fish quality by cold brine was $-12.5^{\circ}C.$

This purpose of this study was to investigate the quality characteristics of jellies added with lemon myrtle extract. Lemon myrtle leaves were extracted for 0, 3, 5, 7, 9 minutes, respectively, in 90℃ water and used for jelly preparation. The moisture content of control showed the lowest value and the content increased significantly as the extraction time of lemon myrtle increased. The pH of L0 was significantly high and increased significantly with the increase of extraction duration time. The lightness value was the lowest in the L3. The redness showed the lowest value in the L9. The yellowness showed the lowest value in the L0. In texture properties the hardness of L9 showed the highest value and the lemon myrtle extraction duration increased significantly. The cohesiveness was highest in the L0 and lowest in the L5. Gumminess and chewiness increased significantly with increasing extraction duration. Total polyphenol content was the highest in the L5 and the jellies with lemon myrtle extracts were significantly higher than the L0. DPPH radical scavenging activities increased significantly with increasing extraction duration. The ABTS radical scavenging activity of the L0 was the lowest. In the sensory evaluation overall preference, color, sweetness, texture, and lemon myrtle flavor did not show any significant differences among the samples.
