  • Xiphasia setifer is reported for the first time from the South Sea of Korea based on a single specimen (291.0 mm SL) collected in September 2010. This species is characterized by the origin of the dorsal fin located vertically above the anterior margin of the eye; dorsal fin rays XIV, 114; anal fin soft rays 114, and vertebrae 130. The new Korean name of the genus Xiphasia is proposed as "Galchi-be-do-ra-chi-sok" and the Korean name of X. setifer as "Gal-chi-be-do-ra-chi", following Yamada et al. (2009).

  • Finite failure NHPP models presented in the literature exhibit either constant, monotonic increasing or monotonic decreasing failure occurrence rates per fault. In this paper, Goel-Okumoto and Yamada-Ohba-Osaki model was reviewed, proposes the hyper-exponential distribution reliability model, which maked out efficiency application for software reliability. Algorithm to estimate the parameters used to maximum likelihood estimator and bisection method. For model determination and selection, explored goodness of fit (the error sum of squares). The methodology developed in this paper is exemplified with a software reliability random data set introduced by of Weibull distribution (shape 0.1 & scale 1) of Minitab (version 14) statistical package.

  • Rumination behavior, in vivo digestibility of cell wall constituents, particle size reduction in the rumen, and retention time in the digestive tract of sheep were examined using rice and oat straw as roughage sources. The in sacco digestibility, rumen fermentation, and microbial population and internal adenosine 5-triphosphate (ATP) content were also determined under feeding conditions of high-roughage and high-concentrate diets. Chewing number and time in rumination behavior were higher with rice straw than with oat straw, while the in sacco and in vivo DMD of rice straw were consistently lower than those of oat straw. Rice straw also showed higher frequency of thinner and longer particles in the rumen contents and lower retention time in the whole digestive tract as compared to those of oat straw. Rice straw was more effective to maintain the ruminal pH than oat straw, being reflected in higher internal ATP content of large-type protozoa on the high- concentrate diet. Changes in the ruminal microflora by shifting from the low- to the high- concentrate diet were also different between rice and oat straw.

  • We discuss the class of projective systems whose supports are the complement of the union of three linear subspaces in general position. We proves these codes are uniquely dtermined up to equivalence by their weight enumerators. Our result is a generalization of the result given in [1].

  • This paper proposes a new 3-D display without glasses using $Moir\acute{e}$ system. It is possible to create a new three-dimensional expression that is different from conventional 3-Dimages. In this study we have geometrically analyzed the process by which moire takes on a three-dimensional property and validated the results of this analysis.

  • We have developed a system that measures the visual contrast of people of various ages (from teens to those in their 70s) when they look at different color patterns. We have applied this system to Web-safe colors (216 colors), and have developed an age-related visual contrast checker that can be used to quickly determine whether a color pattern consisting of any two colors is easy to see.
