  • The purpose of this study is to classify individualism-collectivism into groups and analyze the difference of attitude toward uniform and evaluation criteria toward uniform. Questionnaires are being administered to 369 middle and high school girls in Deagu province. The Frequency, factor analysis, reliability analysis, cluster analysis, correlation analysis, ANOVA, Duncan-test, and t-test are used for data analysis. Individualism-collectivism factors are found to be other focus, individuality focus, competition consciousness, love of family, and self-esteem. Attitude toward uniform are categorized into fashion pursuit, symbol of role, conformity, color, and neatness. Evaluation criteria toward uniform is categorized into 7 factors: practicality, care, promotion, aesthetics, service, brand focus, and regulation focus. Individualism-collectivism are classify into three groups such as high individualism-collectivism, low individuality, and high individuality. Individualism-collectivism shows a significant correlation with the sub-variable attitude toward uniform and evaluation criteria toward uniform. The groups show a significant difference in the attitude toward uniform and evaluation criteria toward uniform. There is a significant difference among individualism-collectivism, attitude toward uniform, and evaluation criteria toward uniform by the middle and high school girls.

  • The genus Daldinia is a member of the Xylariaceae that has brown to dark brown and phaseoliform single cell ascospores with a conspicuous full germ slit. The isolate of D. childiae collected from Mt. Deuk-yu in Korea were compared with similar taxa, D. eschscholzii and D. concentrica.. Ascospores were $11{\sim}13{\mu}m{\times}5.5{\sim}6{\mu}m$ in size, light brown to brown, unicellular, ellipsoid-inequilateral, with dull round ends. Ascospore showed very faint ornamentation at ${\times}7.0k$ magnification. It is one of the main morphological characteristic Korean collection of D. childiae under SEM level and a main reason of reinterpretation of D. concentrica in Korea. Using KOH-extractable pigment color of stroma, D. concentrica that also has supported the SEM level investigation. Daldinia concentrica, having those characteristic recorded in Korea, should be renamed as D. childiae. However, the isolate will be the first record as D. childiae, having precise morphological description in Korea.

  • Odometry is the critical factor to estimate the location of the robot. In the mobile robot with wheels, odometry can be performed using the information from the encoder. However, the information of location in the encoder is inaccurate because of the errors caused by the wheel's alignment or slip. In general, visual odometer has been used to compensate for the kinetic errors of robot. In case of using the visual odometry under some robot system, the kinetic analysis is required for compensation of errors, which means that the conventional visual odometry cannot be easily applied to the implementation of the other type of the robot system. In this paper, the novel visual odometry, which employs only the single camera toward the ground, is proposed. The camera is mounted at the center of the bottom of the mobile robot. Feature points of the ground image are extracted by using median filter and color contrast filter. In addition, the linear and angular vectors of the mobile robot are calculated with feature points matching, and the visual odometry is performed by using these linear and angular vectors. The proposed odometry is verified through the experimental results of driving tests using the encoder and the new visual odometry.

  • This study analyzes consumer-based apparel design elements and evaluation criteria using qualitative research methodology. Apparel design is one of the most important factors to determine consumer consumption and attitude; however, limited studies have examined them. This study provides essential cues for an apparel industry suffering from dramatically fluid market situations. Based on a qualitative analysis of the focus group interviews, researchers establish three categories (basic elements, elements generated by apparel, and elements experienced by consumer) of apparel design elements that are consistent with nine elements (shape, materials, color, pattern, detail, subsidiary materials, overall image & style, fit, and overall balance). The results provide 137 types of conceptualized apparel design evaluation criteria. They developed 56 initial themes, 23 evolved themes, 23 sub categories, and 12 kinds of theme categories with abstract conceptualization. This study explicates the critical role that consumer-based apparel design is the competitive advantage within the apparel industry.

  • A wilt disease occurred on greenhouse-grown eggplants at Yeojoo, Korea in 1997. The wilted eggplants had leaves with gradual yellowing, interveinal necrosis, and marginal crinkling. Vascular tissues of diseased stems were discolored, turned black, and microsclerotia developed at the base of stems. The disease progressed from lower parts of the plants upward. Fungal isolates from discolored vascular tissues were initially whitish to cream color on potato-dextrose agar (PDA) plate, which later turned black due to the formation of microsclerotia. Conidiophores were erect, hyaline, verticillately branched, and had 3 or 4 phialides arising at each node. Phialides were hyaline, arranged in whorls, and measured as 17.5-32.5 x 2-3$\mu\textrm{m}$. Conidia were hyaline, ellipsoidal to sub-cylindrical, mainly one-celled, and measured as 5-8.8 x 2-4$\mu\textrm{m}$. Conidia were borne in small clusters at the tips of phialides. Microsclerotia formed on PDA plates, and consisted of globular cells that formed irregular masses of various shapes. Chlamydospores were absent. Based on these cultural and morphological characteristics, the fungus was identified as Verticillium dahliae Klebahn. Pathogenicity tests by root cutting, root dipping or soil drenching resulted in similar symptoms observed in the naturally infected eggplants. This is the first report on occurrence of Verticillium wilt of eggplant in Korea.

  • Although primordial germ cells(PGCs) have been used in the production of germline chimera, efficiency has not been satisfactory. The Present study was conducted to improve efficiency of germline chimera production using the cultured gonadal PGCs(gPGCs). Germline chimeric chickens were produced by transfer of cultured gonadal primordial germ cells from Korean Ogol Chicken (KOC) to White Leghorn (5.5-day-old) and cultured in vitro for 10 days. Approximately 200 gPGCs (2-day-old) recipient embryos from which blood had been withdrawn via the dorsal aorta prior to the injection. Recipient embryos were incubated until hatching. Germline chimerism of the chickens reaching maturity was examined by mating them with Korean Ogol Chicken. Donor-derived offspring were identified as germline chimeric chickens based on their feather color. The frequency of germline transmission of donor PGCs ranged 1.9∼60.7%. There was no difference between both sexes. Therefore, it can be concluded that efficiency of germline chimerism can be improved via using cultured gPGCs.

  • Two new D-${\pi}$-A dyes were synthesized by the condensation reaction between active methyl and aromatic aldehyde and its biothiol sensing properties in DMSO/water were investigated by UV-vis spectroscopy. Upon addition of $Hg^{2+}$, the solution of D-${\pi}$-A dyes showed color change and the absorption band shows a formation of a dye-$Hg^{2+}$ coordination complex. These dyes exhibited high selectivity for $Hg^{2+}$ as compared with other cations. The dye-$Hg^{2+}$ could be recovered by adding glutathion(GSH). The absorption intensity of dye-$Hg^{2+}$ increased only by the addition of glutathione(GSH). The competition experiments revealed that no obvious interference was observed by performing the titration with the mixture of glutathione(GSH) and other amino acids. The results indicated that these D-${\pi}$-A dyes were highly selective for glutathione(GSH) detection.

  • Free viewpoint TV can provide multi-angle view point images for viewer needs. In the real world, But all angle view point images can not be captured by camera. Only a few any angle view point images are captured by each camera. Group of the captured images is called multi-view image. Therefore free viewpoint TV wants to production of virtual sub angle view point images form captured any angle view point images. Interpolation methods are known of this problem general solution. To product interpolated view point image of correct angle need to depth image of multi-view image. Unfortunately, multi-view video including depth image is necessary to develop a new compression encoding technique for storage and transmission because of a huge amount of data. Layered depth image is an efficient representation method of multi-view video data. This method makes a data structure that is synthesis of multi-view color and depth image. This paper proposed enhanced compression method using layered depth image representation and H.264/AVC video coding technology. In experimental results, confirmed high compression performance and good quality reconstructed image.
