With the development of next IT convergence technology and the construction of infrastructure for personalized healthcare services, the importance of services based on user's preference is being spotlighted. Healthcare service have been progressed as treatment and management for specific diseases and dietary nutrition managements to customers according to the increase in chronic patients. In this paper, we proposed the personalized dietary nutrition contents recommendation using the hybrid filtering for managing health. The proposed method uses the hybrid filtering through combining the collaborative filtering and the image filtering in order to reinforce the special trend that recommendation provides similar contents. We developed the Web application for this purpose, and experimented with it to verify the logical validity and effectiveness. Accordingly, the satisfaction and the quality of services will be improved the healthcare by recommending the dietary nutrition contents. This evaluation found that the difference of satisfaction by service was statistically meaningful and showed high satisfaction.

This study was conducted to investigate the quality characteristics of tofu (soybean curd) prepared with added Cheongyang hot pepper juice (CPJ). The moisture, crude protein, crude lipid, and crude ash contents of the control tofu were 82.98%, 10.26%, 4.86%, and 0.41%, respectively. The moisture content of tofu decreased according to the level of added CPJ, whereas the crude protein, crude lipid, and crude ash contents increased. The yield of tofu prepared with 5% CPJ significantly increased relative to that of control tofu. The turbidity and acidity increased with increasing concentration of CPJ, whereas pH decreased. The Hunter's color values of the tofu were significantly lower in L and a values and significantly higher in b values with increasing concentration of CPJ. The hardness, adhesiveness, and springiness of the tofu samples did not differ significantly according to the level of added CPJ. Capsaicin, dihydrocapsaicin, total polyphenol contents, and antioxidant (DPPH radical and ABTS radical scavenging activity) activities were significantly increased with increasing concentration of CPJ. Sensory evaluation indicated that the tofu prepared with 5% CPJ was not significantly different from the control tofu. Overall, CPJ could be used as an effective ingredient to improve the sensory and antioxidant properties of tofu without affecting the quality properties.

This study was carried out to investigate functional quality characteristics of extract obtained after sugar-leaching for 12 weeks (SLE) and extract obtained after lactic acid fermentation for 8 weeks (LFE) of mulberry leaves. The yield, sugar content, pH, and total acidity of SLE were 27%, 43 $^{\circ}Brix$, 4.6, and 0.45%. The yield, sugar content, pH, and total acidity of LFE were 166%, 33 $^{\circ}Brix$, 3.6, and 1.17% respectively. The lactic acid bacteria viable numbers ($1.2{\times}10^{10}$ CFU/ml) of LFE were more than those of SLE ($2.8{\times}10^2$ CFU/ml). The LFE expressed activities of hydrolytic enzymes (amylase, cellulase, pectinase, protease), but SLE did not express. The contents of acetic acid, citric acid, and malic acid of SLE were higher than those of LFE, but lactic acid content of LFE was higher than that of SLE. The main free sugars of SLE were glucose (200.93 mg/g), fructose (236.32 mg/g), and sucrose (18.41 mg/g), but LFE did not detect all free sugars. The contents of polyphenol, anthocyanin, and piperidine alkaloid of LFE were higher than those of SLE. ${\alpha}$-Glycosidase activities were inhibited 3.4% and 16.2% by SLE and LFE. These results suggest that lactic acid fermentation extraction is an effective method to increase the yield and contents of functional quality of mulberry leaves extract.

In this paper, we propose a classification-based approach for hybridizing statistical machine translation and rulebased machine translation. Both the training dataset used in the learning of our proposed classifier and our feature extraction method affect the hybridization quality. To create one such training dataset, a previous approach used auto-evaluation metrics to determine from a set of component machine translation (MT) systems which gave the more accurate translation (by a comparative method). Once this had been determined, the most accurate translation was then labelled in such a way so as to indicate the MT system from which it came. In this previous approach, when the metric evaluation scores were low, there existed a high level of uncertainty as to which of the component MT systems was actually producing the better translation. To relax such uncertainty or error in classification, we propose an alternative approach to such labeling; that is, a cut-off method. In our experiments, using the aforementioned cut-off method in our proposed classifier, we managed to achieve a translation accuracy of 81.5% - a 5.0% improvement over existing methods.

This paper presents new hole-filling methods for generating multiview images by using depth image based rendering (DIBR). Holes appear in a depth image captured from 3D sensors and in the multiview images rendered by DIBR. The holes are often found around the background regions of the images because the background is prone to occlusions by the foreground objects. Background-oriented priority and gradient-oriented priority are also introduced to find the order of hole-filling after the DIBR process. In addition, to obtain a sample to fill the hole region, we propose the fusing of depth and color information to obtain a weighted sum of two patches for the depth (or rendered depth) images and a new distance measure to find the best-matched patch for the rendered color images. The conventional method produces jagged edges and a blurry phenomenon in the final results, whereas the proposed method can minimize them, which is quite important for high fidelity in stereo imaging. The experimental results show that, by reducing these errors, the proposed methods can significantly improve the hole-filling quality in the multiview images generated.

This study was conducted to compare meat quality traits related to the tenderness of longissimus muscles obtained from domestic and imported steers. A total of 12 steers from three breeds were slaughtered, and were graded as quality grade 2. They were composed of 4 Hanwoo and 4 Holstein steers (domestic) as well as 4 Angus steers (imported from Australia and gained for six months in Korea until slaughtered). The longissimus lumborum muscles were separated and were stored at $4^{\circ}C$ for 7 and 14 d. Sarcomere length of Hanwoo was significantly shorter than Holstein and Angus at storage day 14 (p<0.05). The myofibrillar index was significantly lower on Hanwoo than Angus at ageing day 7, and was significantly lower than Holstein and Angus steers at storage day 14 (p<0.05). Total collagen contents of Hanwoo and Angus steers were significantly higher than Holstein on storage day 7 (p<0.05), whereas soluble collagen contents of Holstein were significantly higher than Hanwoo and Angus on storage days 7 and 14 (p<0.05). There was no significant difference in the fatty acid composition of the three breeds (p>0.05). Glutamic acid contents of Hanwoo and Angus steers were higher than those of Holstein steers at ageing day 7 and 14 (p<0.05). The results of this study have shown that there were no dramatic differences between beef from the three breeds that were fattened for 6 months under equal conditions.

To evaluate peanut sprouts as a functional food material, the quality characteristics and antioxidant activities of soybean yoghurt with different percentages (0.5, 1.0, 2.0, and 3.0%) of peanut sprout powder (PSP) contents were investigated. The pH of soybean yogurt with PSP decreased in a time- and dose-dependent manner during fermentation, whereas the titratable acidity increased under the same conditions. The Hunter L value (lightness) decreased while the b value (yellowness) and a value (redness) increased as the PSP concentration in soybean yogurt increased. Prior to fermentation, the sugar content of the soybean yogurt increased as the PSP level increased, but the contents decreased as fermentation progressed. Meanwhile, the viscosity of the soybean yogurt increased during fermentation, and the lactic acid bacteria population was higher than that of the control. The sensory properties, including the flavor, color, taste, and overall acceptability, of the soybean yogurt containing 0.5 and 1% PSP, respectively, were higher than those of other tested yoghurts (with 0, 2.0, and 3.0% PSP contents). The antioxidant activity of the soybean yogurt significantly increased at the PSP concentrations of over 1.0%. These results suggest that the addition of PSP has beneficial effects on the quality and functionality of soybean yogurt, and that the addition of 1.0% PSP is the most suitable for manufacturing soybean yogurt.
