  • The present study replaced Atarigoma with Korea &Chinese sesame values a nd analyzed basic data on various mook to develop Korea's food culture. Contents of oleic acid and linolenic acid in sesame seed were 42.31% and 48.18%, respectively, with a total moisture content of 89.5%. As storage temperature increased, moisture content increased. Cohesiveness and springiness decreased gradually at $4^{\circ}C$ and increased at $20^{\circ}C$, whereas gumminess and chewiness increased at $4^{\circ}C$ and gradually decreased at $20^{\circ}C$. Overall acceptability scores of Japanese and Korean arrowroot starch sesame mook were 7.20 and 7.10, respectively. Korea and Japanese Sesame can be substituted for sweet potato starch, potato starch, and arrowroot starch.

  • The anatomical structure of fusiform ray was examined by scanning electron microscopy (and microscopic images were analysed by image analyser) to explain the differences in radial fluid uptake between the extremes in the radial treatment data, i.e. between the selected trees of QCI (Queen Charlotte Islands in Rhondda, South Wales) and SO (South Oregon in Dalby, North-East England) planted in the UK. The ray structure of these two seed origins was examined microscopically and different patterns of ray composition were observed. The most important anatomical features influencing radial permeability were the nature of fusiform ray, and the condition of the resin canals, epithelial cells and intercellular spaces in particular.

  • The purpose of this study si the development of a lathe which can cut any pistons of oval shape with high seed, accuracy and precision by CNC (Computer Numerical Control) method. Yaxis which is the position determinating mechanism with high speed response was added to the CNC lathe and the ovality and profile was cut under the control of C-Y-Z axes at same tile. In the case of ovality of $\Phi$ improved up to 2500rpm(Y axis : 83Hz) by high speed cutting than modeling method. Since a personal computer is used, it is easy to change the shape of piston and can be applied promptly to many types of piston shape by only changing data files.

  • In this paper, I propose the wavelet image coding method using band adaptive quantization and the significant cluster extraction. The proposed method can reduce to unnecessary additional seed data which create on conventional MRWD coding, because it eliminate cluster which smaller than structuring element by using morphology. And it make fast coding possible, because it is reduced to computational complexity by using band adaptive quantization. Consequently, the proposed method reduces computational complexity with $20\%{\~}33.3\%$ according to bit rate in quantization process.

  • Zeins, maize storage proteins, are retained in the endoplasmic reticulum (ER) during the subcellular targeting process without the ER retention signal. Circumstantial data indicate that the 27K zein is an ER transmembrane protein. The potential transmembrane domain may permit the 27K zein to remain in the ER. This study investigated the potential transmembrane feature by employing alkaline extraction, proteinase K digestion, and surface biotinylation on isolated intact protein bodies. These assays consistently support the possibility of the 27K zein as a transmembrane protein. The 27K zein polypeptide was shown to be associated with alkali-stripped membranes. The polypeptide was digested by proteinase K to a smaller fragment. According to surface biotinylation, the 27K zeins was labeled to the exclusion of other classes of zeins. This study, therefore, concludes that the 27K zein has an ER transmembrane domain, which may serve as an anchor for zeins' ER retention.

  • In this study, we investigated a dose-dependent hypolipidemic and antioxidant effects of tocotrienol-rich fraction (TRF) from grape seeds. After induction of hyperlipidemia for 4 weeks, rats were supplemented with different dose (5, 25, and 50 mg/kg BW/day) of TRF for 1 week. Oral administration of TRF (50 mg/kg BW/day) decreased the plasma triglyceride (TG, 162.6 mg/dL), total cholesterol (TC, 83.7 mg/dL), low density lipoprotein-cholesterol (LDL-C, 20.3 mg/dL), malondialdehyde contents (MDA, 3.3 nmol/dL), and atherogenic index (AI, 2.0) compare to high-fat diet group. These data suggest that TRF supplementation has significant health benefits through the modulation of physiological functions that include various atherogenic lipid profiles and antioxidative status in hyperlipidemia.

  • This paper proposes a novel image authentication scheme, aiming at tampering detection for block truncation coding (BTC) compressed image. The authentication code is generated by using the random number generator with a seed, and the size of the authentication code is based on the user's requirement, with each BTC-compressed image block being used to carry the authentication code using the data hiding method. In the proposed scheme, to obtain a high-quality embedded image, a reference table is used when the authentication code is embedded. The experimental results demonstrate that the proposed scheme achieves high-quality embedded images and guarantees the capability of tamper detection.

  • Bacillus subtilis JW-1 was isolated from rhizosphere soil as a potential biocontrol agent of bacterial wilt caused by Ralstonia solanacearum. Seed treatment followed by a soil drench application with this strain resulted in >80% reduction in bacterial wilt disease compared with that in the untreated control under greenhouse conditions. The antibacterial compound produced by strain JW-1 was purified by bioactivity-guided fractionation. Based on mass spectroscopy and nuclear magnetic resonance spectral data ($^1H$, $^{13}C$, $^1H-^1H$ correlation spectroscopies, rotating frame nuclear Overhauser effect spectroscopy, and heteronuclear multiple-bond correlation spectroscopy), the structure of this compound was elucidated as a cyclic lipopeptide composed of a heptapeptide (Gln-Leu-Leu-Val-Asp-Leu-Leu) bonded to a ${\beta}$-hydroxy-iso-hexadecanoic acid arranged in a lactone ring system.
