The purpose of this study was to examine the quality characteristics of cookies made with Angelica gigas Nakai fermented by Lactobacillus paracasei. As the content of Angelica gigas Nakai fermented by L. paracasei (AFL) powder increased, the pH of the cookies decreased from 6.3 to 5.2. There was no significant difference in the moisture content depending on AFL powder content. The content of reducing sugar also increased with increasing AFL powder content. Regarding the surface color of the cookies, the L- and b-values decreased with increasing AFL powder content, whereas the a-value increased. As the AFL powder content increased, the total polyphenol content and ABTS and DPPH radical scavenging activities significantly increased. Cookies with 8% AFL powder (AC8) had the highest levels of 107.16 mg%, 38.69%, and 65.56%, respectively. The texture, adhesiveness, and cohesiveness of the cookies with various AFL powder levels were not significantly different, and hardness, springiness, gumminess, and chewiness showed no tendencies toward changes. Taken together, these results showed that when AFL powder was added to cookies, bioactivities such as antioxidant activity increased, making AFL powder a good material with high potential for use in commercially baked products.

Purpose: Long Extension (LE) is used in proton therapy for lung and abdomen. However, it has limitations in surface area, produces collision in posterior oblique beam which creates limitations in various gantry angles in planning therapy and increases air gap (distance between patient and compensator). Therefore, this study investigates the usability of manufactured Rounded Extension (RE) in comparison to LE to use the most suitable extension in proton therapy. Materials and Methods: To compare structural features of LE and RE. This study investigated usable gantry angle for snout sizes 100, 180 and 250 and CT scanned Humanoid phantom. And it compared the air gap in posterior oblique direction. Results: The structural features of two extensions are as follow. Because of the existence of supporting bar, the width of LE was 40 cm and RE was 50 cm. Result of the investigation of usable gantry angle for snout sizes 100, 180 and 250 are as follow. LE is ${\pm}36$ (average) at 180 degree and RE is ${\pm}70$ (average). And also, the air gap of RE is decreased by 11.3 cm in average at the same gantry angle. Conclusion: Manufactured RE for proton therapy has several benefits than LE. Its therapy surface area is wider and range of usable gantry angle is also wider. Also, the air gap at the posterior oblique beam has decreased. Therefore the usability of RE in proton therapy of lung and abdomen will be increased compared to LE. However, the air gap of proton therapy at the lateral direction may be increased, so there may be need for make up to decrease air gap at the lateral direction in the future.

Altimeter(Topex/Poseidon) and AVHRR(NOAA) data were used to study the variations and correlations of Sea Level(SL) and Sea Surface Temperature (SST) in the North East Asian Seas from November 1993 to May 1998. This region is influenced simultaneously to continental and oceanic climate. SL and SST have increased gradually every year because the global warming, and presented usually a strong annual variations in Kuroshio extension region with the influence of bottom topography.

Using the Huckel method, we obtain the analytical expressions for eigenvalues and eigenvectors of s.c., f.c.c. and b.c.c. clusters of rectangular parallelepiped shape, and of an arbitrary size. Our formula converage to those derived from the Bloch sum, in the limit of infinite extension. DOS and LDOS reveal that the major contribution of the states near Fermi level originates from the surface atoms, also symmetry of DOS curves disappears by the introduction of 2nd nearest neighbor interactions, in all the cubic lattices. An accumulation of the negative charges on surface of cluster is observed.

Dual response surface optimization (DRSO), inspired by Taguchi's philosophy, attempts to optimize the process mean and variability by using response surface methodology. Researches on DRSO were extensively done in 1990's and have been matured recently. This paper reviews the existing DRSO methods from the decision making perspective. More specifically, this paper classifies the existing DRSO methods based on the optimization criterion and the timing of preference articulation. Also, some of case studies are reviewed. Extension to multiresponse optimization, triple response surface optimization, and application of data mining method are suggested as future research issues.

Stationary and rotating blades can be found in a steam turbine generator and the airfoil shapes of these blades can be defined by point data from an aerodynamic design system. The main design process of blades is composed of two steps: first, the blade surface is modeled with the point data; and then, the section data is generated which contains composite curves with line segments and arcs for CAE of the blade. The surface is modeled by a curve-net defined by the point data, which may be extended to obtain the section data to model the blade. This paper presents methods for automating the above-mentioned steps, which have been implemented in the commercial CAD/CAM system, Unigraphics, with API functions written in C-language. Finally, the proposed methods have been applied to model the blade of a steam turbine generator.

During July to November 2014, severe rust infection was consistently found on Peucedanum japonicum growing farm in Yeosu, Korea. The rust was observed mainly on lower leaf surfaces. Symptoms of typical plants included yellow-orange rust pustules were observed on the petiole and leaf surface with small yellowish to chlorotic lesions on the upper surface. No symptom was observed on flowers. Uredinia were occurred amphigenous on leaf surface, and occasionally caulicolous, scattered or loosely aggregate, rounded to oblong, 0.4 to 4 mm in diameter, covered by epidermis, then naked, surrounded by ruptured epidermis, pulverulent, and brown. Urediniospores were ovate-ellipsoid, ellipsoid or subglobose, light brown, 20 to $45{\times}15$ to $35{\mu}m$, walls 2 to $4{\mu}m$ thick. The resulting sequences were deposited in GenBank with accession No. KT778808, KT778809, and KT778810, respectively. Since this was the first accession of 28S sequence Puccinia jogashimensis, there was no exact match in GenBank nucleotide database. On the basis of the morphological characteristics and phylogenetic analyses of 28S rDNA, the fungus was identified as P. jogashimensis. To our knowledge, this is the first confirmed report on the occurrence of P. jogashimensis on P. japonicum in Korea.

Objectives: To analyze the influence of thickness and incisal extension of indirect veneers on the stress and strain generated in maxillary canine teeth. Materials and Methods: A 3-dimensional maxillary canine model was validated with an in vitro strain gauge and exported to computer-assisted engineering software. Materials were considered homogeneous, isotropic, and elastic. Each canine tooth was then subjected to a 0.3 and 0.8 mm reduction on the facial surface, in preparations with and without incisal covering, and restored with a lithium disilicate veneer. A 50 N load was applied at $45^{\circ}$ to the long axis of the tooth, on the incisal third of the palatal surface of the crown. Results: The results showed a mean of $218.16{\mu}strain$ of stress in the in vitro experiment, and $210.63{\mu}strain$ in finite element analysis (FEA). The stress concentration on prepared teeth was higher at the palatal root surface, with a mean value of 11.02 MPa and varying less than 3% between the preparation designs. The veneers concentrated higher stresses at the incisal third of the facial surface, with a mean of 3.88 MPa and a 40% increase in less-thick veneers. The incisal cover generated a new stress concentration area, with values over 48.18 MPa. Conclusions: The mathematical model for a maxillary canine tooth was validated using FEA. The thickness (0.3 or 0.8 mm) and the incisal covering showed no difference for the tooth structure. However, the incisal covering was harmful for the veneer, of which the greatest thickness was beneficial.
