  • This study was evaluated to biological activity of breeding lines from Acantopanax( A. sessiliflorus: ASF, A. koreanum: AKN, A. chiicanensis: ACS, A. senticosus: AST) and parts(root, stem, fruit, and leaf) and various extracted solvents( 100% water, 100% EtOH, 50% EtOH). Total polyphenol content of AKN root in 100% water extracts was high detected 464.46 mg/100 g. Total flavonoid content in the leaf was significantly higher than in other parts. The content of total sugars was high in the 50% EtOH extracts and fruit. The major free amino acids were arginine in all extracts. The content of arginine was detected in the root of AKN(1.807 mg/100 mg). Contents of eleutheroside B, E were high detected in 100% water extracts. Antioxidative capacity in the leaves of AKN was the higher than other extracts($EC_{50}=84.8{\mu}g/mL$). The results would be useful for understanding of the physiological properties of AKN extracts.

  • The Food and Agriculture Organization (FAO) has been estimating the potential of insects as human food and animal feed for convincing food security since 2010. On account of this reason, Tenebrio molitor larvae have been gaining considerable attention as an alternative protein source for various foods. However, consumers do not prefer them because of their disgusting appearance. Therefore, it is necessary to develop a method that improve their appearance as to lead to T. molitor larvae consumption. In this study, T. molitor larvae which is prepared for optimally sampling conditions (shade drying, 30 min boiling after hot air drying, 30 min steaming after hot air drying), were cultured with Cordyceps militaris mycelia, and measured growth and density of mycelial. Also analyzed the cordycepin and adenosine content compared with commercial C. militaris. As a result, T. molitor larvae cultivated with C. militaris mycelia showed the highest cordycepin content (13.75 mg/g) was observed in optimal sampling conditions (shade drying). Therefore, we report that the methods which T. molitor larvae cultivated with C. militaris mycelia not only improve their appearance but also increase cordycepin content, which can be contributed to lead T. molitor larvae consumption.

  • The effects of replacing pork meat with yellow mealworms on the physicochemical properties and sensory characteristics of frankfurters were investigated in this study. The control (50% pork ham), T1 (45% pork ham + 5% yellow mealworm), T2 (40% pork ham + 10% yellow mealworm), T3 (35% pork ham + 15% yellow mealworm), T4 (30% pork ham + 20% yellow mealworm), T5 (25% pork ham + 25% yellow mealworm), and T6 (20% pork ham + 30% yellow mealworm) were prepared, replacing lean pork meat with yellow mealworm. The moisture content, lightness, sarcoplasmic protein solubility, hardness, gumminess, chewiness, and apparent viscosity of frankfurters with yellow mealworm were lower than those of the control (p<0.05), whereas the content of protein and ash, pH, and yellowness of frankfurters with yellow mealworm were higher than those of the control (p<0.05). The fat content of frankfurters in T1 (p<0.05) was the highest, and the fat content of treatments decreased with increasing yellow mealworm concentrations (p<0.05). Frankfurters with increasing yellow mealworm concentrations had lower color, flavor, off-flavor, and juiciness scores. The overall acceptability was not significantly different in the control, T1, and T2 (p>0.05). Thus, the results of this study showed that replacing lean pork meat with up to 10% yellow mealworm successfully maintained the quality of frankfurters at a level similar to that of the regular control frankfurters.

  • The effects of binder and alumina content on the setting time, drying shrinkage, strength, freezing and thawing resistance and water absorption of polymer-modified pastes with alumina powder were examined. As a result the setting time of the polymer-modified pastes with alumina powder tended to delay with increasing binder content. Irrespective of the type of polymer, the drying shrinkage of the polymer-modified pastes with alumina powder tended to decrease with increasing binder content and alumina powder content. Regardless of the type of polymer, the tensile and adhesion strengths of the polymer-modified pastes with alumina powder tended to increase with increasing binder content and alumina powder content. Irrespective of the type of polymer, the durability factors of the polymer-modified pastes with alumina powder tended to increase with increasing alumina content. Irrespective of the type of polymer, the water absorptions of the polymer-modified pastes with alumina powder tended to decrease with increasing binder content and alumina content.

  • The effects of ethaverine on serotonin biosynthesis in murine mastocytoma P815 cells were investigated. Ethaverine at 2.5${\sim}$10 ${\mu}$M decreased serotonin content in a concentration-dependent manner. The IC$_{50}$ value of ethaverine was 6.1 ${\mu}$M. Ethaverine at concentrations up to 20 ${\mu}$M was not cytotoxic towards P815 cells. Under these conditions, tryptophan hydroxylase (EC 1.14.16.4; TPH), a rate-limiting enzyme in serotonin biosynthesis, was inhibited by ethaverine in P815 cells (15.3% inhibition at 7.5 ${\mu}$M), however, aromatic L-amino acid decarboxylase (EC 4.1.1.28) was not. These results indicate that ethaverine leads to a decrease in serotonin content by reducing TPH activity in P815 cells.

  • Licorice(Glycyrrhizae Radix et Rhizoma) is recorded as the root of Glycyrrhiza uralensis Fischer or Glycyrrhiza glabra Linne or Glycyrrhiza inflata Bat.(Leguminosae) in Korean Pharmacopoeia $9^{th}$ edition (KP9) and Chinese Pharmacopoeia 2005(CP2005), Glycyrrhiza uralensis Fischer or Glycyrrhiza glabra Linne in Japanese Pharmacopoeia 2005(JP2005). It is established the content standard of Glycyrrhizin 2.5 % and liquiritin 1% in KP9 and CP2005. But, according to the reports, all Licorice species were not sufficient for content standard of liquiritin 1.0% for licorice in KP9 and CP2005. It shows different content of liquiritin among G. uralensis, G. glabra and G. inflata. Also, it was reported liquiritin, liquiritin apioside are transformed into liquiritigenin by human internal flora. Therefore, we have studied for the pre-treatment condition and analytical method of liquiritigenin; It was good efficinet in 2M HCl reflux(1 hr) for hydrolysis and in methylene chloride for solvent fractionation. And 1% acetic acid in DW(A) and acetonitrile(B) with gradient condition as a mobile phase was most effective in HPLC analytical condition. According to these experimental methods, we have anlayzed content of liquiritigenin about 77 Licorice sample. In this research, it was also examined the content of liquiritin and liquiritigenin for Glycyrrhizae Radix related growing area. According to the results, we suggested the content standard of glycyrrhizin more than 2.5%, liquiritigenin more than 0.7%(after hydrolysis) of licorice.

  • We address the problem of uncooperative person recognition through continuous monitoring. Multiple modalities, such as face, height, clothes color, and voice, can be used when attempting to recognize a person. In general, not all modalities are available for a given frame; furthermore, only some modalities will be useful as some frames in a video sequence are of a quality that is too low to be able to recognize a person. We propose a method that makes use of stochastic information updates of temporal modalities and environment estimators to improve person recognition performance. The environment estimators provide information on whether a given modality is reliable enough to be used in a particular instance; such indicators mean that we can easily identify and eliminate meaningless data, thus increasing the overall efficiency of the method. Our proposed method was tested using movie clips acquired under an unconstrained environment that included a wide variation of scale and rotation; illumination changes; uncontrolled distances from a camera to users (varying from 0.5 m to 5 m); and natural views of the human body with various types of noise. In this real and challenging scenario, our proposed method resulted in an outstanding performance.

  • Various simulation applications for hair, clothing, and makeup of a 3D avatar can provide more useful information to users before they select a hairstyle, clothes, or cosmetics. To enhance their reality, the shapes, textures, and colors of the avatars should be similar to those found in the real world. For a more realistic 3D avatar color reproduction, this paper proposes a spectrum-based color reproduction algorithm and color management process with respect to the implementation of the algorithm. First, a makeup color reproduction model is estimated by analyzing the measured spectral reflectance of the skin samples before and after applying the makeup. To implement the model for a makeup simulation system, the color management process controls all color information of the 3D facial avatar during the 3D scanning, modeling, and rendering stages. During 3D scanning with a multi-camera system, spectrum-based camera calibration and characterization are performed to estimate the spectrum data. During the virtual makeup process, the spectrum data of the 3D facial avatar is modified based on the makeup color reproduction model. Finally, during 3D rendering, the estimated spectrum is converted into RGB data through gamut mapping and display characterization.
