The fungal isolates of Mucorales, directly collected from Korean traditional raw materials of Nuruk (raw material for Korean rice wine) and Meju (raw material for Korean soysauces), were compared with those of Rhizopus oryzae purchased. The fungal isolates of Rhizopus, Mucor, and Absidia mostly identified as based on the morphological observations, were evaluated with the PCR-polymorphic bands. The PCR-polymorphic bands of the genomic DNA reacted with the primers of OPD series tenmer were various, but showed averaged 4 to 6 in the agarose-electrophoresis. The dissimilarity coefficient (DC) between two isolates were compared by the cluster analyses, dendrogams and polar ordinations. The isolates of R. oryzae known. showed several groupings within the lower value of DC and were divided to two groups of amylo-process and other fungi with other purposes. The isolates unidentified were identified by the DC made of this results. Taxonomy of these isolates made by the morphological observations were consistent with those resulted above in most case but not in all aspects. More works were needed with the isolates known for detail informations of Mucorales.

The fuel rods in the pressurized water reactor are continuously supported by a spring system called a spacer grid which is one of the main structural components for the fuel rod cluster (fuel assembly). The fuel rods are vibrating within the reactor due to coolant flow. Since the vibration, what is called flow-induced vibration(FIV), can wear away the surface of the fuel rod, it is important to understand the vibration characteristics of it. In this paper, the vibration analyses and the tests for the dummy rods supported by New Doublet(ND) spacer grids are described. A new FE model which reflects the contact area between the rod and ND spacer grid spring is developed to replace the previous one by which a good agreement could not be obtained with the vibration test. The natural frequency and mode shape calculated by both the previous FE model and the new one are compared with those of experiment fur a single-spanned rod supported by two ND spacer grids. The results by the new model show good agreement to experiment as compared with the ones by previous model. In addition, the new FE model is applied to the vibration analysis fur the dummy rod of 2.19 m tall continuously supported by five ND spacer grids. It is also obtained that the analysis results by the new FE model well agree to experiment ones as the single-spanned rod.

The aim of this study was to analyze e-commerce sites of luxury fashion brands in order to provide insights on how to enhance online site quality. For the research, forty-eight components of thirty-one luxury fashion brands' e-commerce sites were investigated during October 2013. For the analysis of clustering e-commerce site components and segmenting e-commerce sites of luxury brands, a hierarchical cluster analysis was applied through using the Ward's method and squared Euclidian distance for binary data. Further, Fisher's exact test was applied in order to distinguish three groups of characteristics in the luxury e-commerce sites. These analyses were carried out by SPSS 21. The result indicated that the components of e-commerce sites were grouped into three categories: basic elements, additional elements and elements of building brand identity. These components were categorized by whether their functions were basic and essential or additional and advanced. The other norm of categorization was related to brand identity. Furthermore, the luxury brands' e-commerce sites were segmented into three groups: a group of endeavoring to promote goods, a group of undistinguished performance, and a group of endeavoring to intensify brand identity. In this segmentation, brand identity or promotional aspects were decisive. Overall, luxury brands were trying to convey their traditional strength through their e-commerce sites. In order to achieve this purpose, brand identity or promotional aspects played an important role.

This study was conducted to examine the physicochemical properties and consumer acceptability of commercial Gang-jeong. The samples used in this study were nine different Gang-jeong as commercial products. To accomplish this research, the physicochemical properties of nine samples, including moisture, crude lipid, sugar contents, acid value, color values, and texture, were measured. In addition, consumer panels evaluated the overall acceptability, appearance, flavor, sweetness, and texture of samples using a 9-point Likert type scale as well as the perceived intensities of sweetness and rancid odor by a 9-point Just-About-Right (JAR) scale. All data were statistically analyzed using One-way ANOVA, Principle Component Analysis, Hierarchical Cluster Analysis, and Pearson's Correlation Analysis. All physicochemical properties were significantly different among the samples (p<0.001). Analyses of consumer acceptability and JAR ratings of the nine samples showed significant differences (p<0.001).

This study examined bag purchase behaviors for male consumers based on fashion attitudes. Data research were conducted on 304 males in their 20s and 30s located in Seoul & Gyeonggi province. The SPSS 17.0 software program was used to conduct data analyses such descriptive statistics, frequency analysis, factor analysis, cluster analysis, $X^2$-test, t-test, ANOVA, and Scheffe's test as a post-hoc analysis. The results of this study were as follows: Fashion attitude was identified with four factors personality, social recognition, practicality, and dignity. Customers were segmented into three subdivisions: conspicuous, recognition of individual style, and practicality of clothing. The factors derived from the factor analysis of selection criteria included intrinsic attributes and extrinsic attributes. Males in their 30s valued the intrinsic attributes and males in their 20s valued extrinsic attributes. The group of conspicuous of clothing, valued both intrinsic and extrinsic attributes as important. The factors derived from the factor analysis of bag pursuit benefit included pursuit of fashion/economic, famous brand, quality/convenience. Males in their 20s and 30s pursued famous luxury brands and fashion attitudes had a positive relevance to the bag pursuit benefit.

The purpose of this study was to observe lifestyle of female consumers aged 15-25. Also it was to measure brand awareness, to determine purchase criteria in fashion magazine, and to determine promotion preferences according to lifestyle segmentation variables. We distributed 600 questionnaires and 475 reliable questionnaires were used for a statical analysis. Data analyses were conducted with SPSS program on the frequency mean value, Chi-square test, Cluster analysis, and Factor analysis. We classified four clusters such as individual style seekers, trend seekers, promotion/good appearance seekers, and low fashion interest group, based on lifestyle variables. There was a significant difference in brand awareness in Vogue Girl, Cosmo Girl, Elle, Figaro, Ecole magazine among four clusters. There was a significant difference in such purchase criteria as favorable cover models, good "burok" which is a magazine supplement, brand names, and price among four clusters. In addition, the results of ANOVA represent that there was a significant difference in preferred types of promotion such as discount price, clothing gifts, fashion accessary gifts and hair tool gifts. However, the first ranked preferred one was a cosmetic gift in all the magazines, which favored more by trend seeker group.

The purpose of this study was to investigate the differences in adolescents' conspicuous consumption, and their attitude toward and purchasing behaviors for the imported luxuries and the famous brand clothing. A questionnaire survey was conducted to 570 high school students in Seoul; 538 were used for final data analysis. Factor analysis, cluster analysis, $\chi$$^2$-analysis, one-way ANOVA, Duncan's Multiple Range test were used for the statistical analyses. In terms of conspicuous consumption, three factors were formulated: brand and fashion orientation, others orientations, and prize and import orientation. Based on the factor scores, three clusters were identified: the inconspicuous, the others-oriented conspicuous, and the brand-oriented conspicuous. Regarding attitudes toward the products, significant differences were found in all attitudes. The brand-oriented conspicuous showed more favorable attitude toward the products than the other groups. Significant differences were also found in purchasing behaviors except the companions for shopping and purchase time. The brand-oriented conspicuous tended to purchase more, spend more money, prefer department stores, consider brand name and customer service as the most important criteria, and use impersonal informations sources when shopping the products. The other-oriented conspicuous tended to buy bogus products the most, use personal information and consider price and others' perception as important criteria. The inconspicuous were less likely to buy and spend money for the products.

The intraspecific variability, habitats, and morphological characteristics of eelgrass (Zostera marina L.) along the eastern coast of Korea were examined during June to August 1998. Morphological characteristics including shoot height, leaf length, leaf width, number of leaf veins, and shape of leaf apex were measured, and eelgrass habitats were analyzed using character correlation, principal components and cluster analyses. The morphological characteristics varied with the habitat types and water depth. Eelgrass beds distributed mostly in lagoons, ports and bays along the east coast of the Korean peninsula. The quantitative morphological features that enabled recognition of the two phonetic groups were short- narrow and long-broad leaf types. Leaf apex in particular varied with the habitat characteristics.

This study investigated the relationships among proper types of e-commerce, patterns of inter-organizational information flow (IIF), benefits of e-commerce, and supply-chain performance. In IIF, it was empirically observed that environmental competition positively influences the frequency of IIF, and environmental uncertainty has a positive impact on the quality of IIF. It was also empirically confirmed that only quality of IIF has effects on the usage levels of e-procurement as well as e-partnerships. Through regression analyses and cluster analysis, it was found that under high degrees of the frequency and quality of IIF, the benefits of e-commerce are vastly realized in the firms that highly utilize e-partnerships. The results of this study also showed that when the degrees of quality of IIF are high, the levels of benefits of e-commerce are increased in the firms that employ e-procurement. The moderating effects of buyer and supplier firms' abilities on the relationships between patterns of IIF and usage levels in various types of e-commerce were empirically examined. According to the results, the moderating roles of buyer firms' capabilities and suppliers' abilities were partially demonstrated. Finally, it was found that the realization of benefits of e-commerce can lead to the improvement of supply-chain performance.
