The aim of this study is to define the concept of the matchless, and its social and cultural origins. I shall also define the different types of Matchless style, the respective characteristics of each style, and the distinguishing features of this style in domestic street fashion. In order to do this, 1 have referred to several published studies and a number of Web-sites of Korean fashion information companies for my research. The results of this study are the following; 1. The concept of matchless is a positive way of self-expression by coordination, created by consumers who attach great importance to their image and to developing their individual style. Also, this concept constitutes a new approach to code which reanalyzes existing styles with a new sensitivity. 2. The social & cultural origins of matchless are the expansion of fear of war and terror, and economic depression, the extension of the 5-day workweek, interest in 'Well-being', and the phenomena of cultural diversity. 3. The types of Matchless are Style Matchless, Theme Matchless, Texture Matchless, Season Matchless, and Complex-Layered Matchless. 4. The distinguishing features of Matchless in street fashion are the distinction of formal & Casual wear's Matchless, the creation of a new Look in Sports & Casual wear's Matchless, the development of a new coordinated, layered look, the immense popularity of Denim, the new fashionable versions of Military style, and the renaissance of the Romantic Feminine Look.

This study was carried out to differentiate the origins of Astragalus membranaceus Bunge and A. membranaceus Bunge var. mogholicus Nakai. To identify the variation of the RAPD patterns between domestic and foreign Astragalus species, 40 random primers were applied to ten accessions of A. membranaceus and six accessions of A. membranaceus var. mogholicus genomic DNA, respectively, Ten primers of 40 primers could be used to discriminate the origins and 33 polymorph isms among 44 scored DNA fragments (33 fragments are specific for A. membranaceus and A. membranaceus var. mogholicus) were generated using these primers, 75.0 % of which were polymorphic. Especially, three primers of ten primers, OPA17, OPA11 and OPB11, were useful to differentiate between domestic and foreign Astragalus species. RAPD data from the 10 primers were used for cluster analysis and cluster analysis of RAPD markers showed that the two groups are distinct genetically. Consequently, RAPD analysis was a useful method to discriminate between A. membranaceus and A. membranaceus var. mogholicus.

The economy blocking and price competitiveness caused by globalization has generated an on-going controversy of global sourcing among high-priced luxury brands. The consumers in the global market purchase luxury goods based on both craftsmanship and the reputation of luxury brands. Factors such as the origin, brand and pricing can affect the intention of consumers to buy luxury goods. This study analyzed the optimum brand combination using conjoint analysis. The analysis was based on the selection of origin, brand name and price as extrinsic factors among attributes of customer choice. These factors were subdivided into Italian and Chinese origins, Gucci, Prada, and Miu Miu in terms of brand names, and 450,000, 750,000, and 1,500,000 Won in terms of price levels. The result showed that origin was considered the most important factor followed by brand name and pricing. This tendency tells us that customers consider origin, brand name and price in that order when purchasing luxury brands. In regards to each factor, respondents preferred Italian to Chinese origins, the Gucci to Miu Miu brand name, and 750,000 to 450,000 won for price level. Generally, women in their 20s and 30s preferred products from advanced nations at a medium-level price.

In Japan, the wild house mouse Mus musculus consists of two lineages, one from Southeast Asia (Mus musculus castaneus; CAS) and one from northern Eurasia (Mus musculus musculus; MUS). However, the exact origins of the parental lineages are unclear. A recent work using mitochondrial sequences revealed that Japanese CAS and MUS are closely related to haplotypes from South China and the Korean Peninsula, respectively. Recent phylogeographic analyses using nuclear gene sequences have also confirmed a close relationship between Japan and Korea in the MUS component. However, the Japanese CAS components in the nuclear genome are likely to be unique and to differ from those of other CAS territories, including South China. Although the origins are still unresolved, these results allow us to conclude that two areas of the continent, South China and the Korean Peninsula, are the primary source areas of Japanese wild mice and suggest pre-historical introductions associated with certain historical agricultural developments in East Asia.

Rapid geographical classification of Bupleuri Radix is important in quality control. In this study, near infrared spectroscopy (NIRS) combined with supervised pattern recognition was attempted to classify Bupleuri Radix according to geographical origins. Three supervised pattern recognitions methods, partial least square discriminant analysis (PLS-DA), quadratic discriminant analysis (QDA) and radial basis function support vector machine (RBF-SVM), were performed to establish the classification models. The QDA and RBF-SVM models were performed based on principal component analysis (PCA). The number of principal components (PCs) was optimized by cross-validation in the model. The results showed that the performance of the QDA model is the optimum among the three models. The optimized QDA model was obtained when 7 PCs were used; the classification rates of the QDA model in the training and test sets are 97.8% and 95.2% respectively. The overall results showed that NIRS combined with supervised pattern recognition could be applied to classify Bupleuri Radix according to geographical origin.

For model calibration in rainfall-runoff modeling, streamflow data at a specific outlet is obviously required but is not sufficient to identify parameters of a model since numerous parameter combinations can result in very similar model performance measures (i.e. objective functions) and indistinguishable simulated hydrographs. This phenomenon has been called 'equifinality' due to inherent parameter uncertainty involved in rainfall-runoff modeling. This study aims to investigate catchment responses in time and space to various uncertain parameter sets in distributed rainfall-runoff modeling. Seven plausible (or behavioral) parameter sets, which guarantee identically-good model performances, were sampled using deterministic and stochastic optimization methods entitled SCE and SCEM, respectively. Then, we applied them to a computational tracer method linked with a distributed rainfall-runoff model in order to trace and visualize potential origins of streamflow at a catchment outlet. The results showed that all hydrograph simulations based on the plausible parameter sets were performed equally well while internal catchment responses to them showed totally different aspects; different parameter values led to different distributions with respect to the streamflow origins in space and time despite identical simulated hydrographs. Additional information provided by the computational tracer method may be utilized as a complementary constraint for filtering out non-physical parameter set(s) (or reducing parameter uncertainty) in distributed rainfall-runoff modeling.

Eighty-five Enterococcus faecalis isolates collected from animals (40 isolates), meju (a Korean fermented soybean product; 27 isolates), humans (10 isolates), and various environmental samples (8 isolates) were subjected to multilocus sequence typing (MLST) to identify genetic differences between samples of different origins. MLST analysis resulted in 44 sequence types (STs), and the eBURST algorithm clustered the STs into 21 clonal complexes (CCs) and 17 singletons. The predominant STs, ST695 (21.1%, 18/85) and ST694 (9.4%, 8/85), were singletons, and only contained isolates originating from meju. None of the STs in the current study belonged to CC2 or CC9, which comprise clinical isolates with high levels of antibiotic resistance. The E. faecalis isolates showed the highest rates of resistance to tetracycline (32.9%), followed by erythromycin (9.4%) and vancomycin (2.4%). All isolates from meju were sensitive to these three antibiotics. Hence, MLST uncovered genetic diversity within E. faecalis, and clustering of the STs using eBURST revealed a correlation between the genotypes and origins of the isolates.

The objective of this study was to trace the origins of the costume terminologies and to identify the meanings of the names of costumes of the Chosun Period. Such terms as dukgai 得盖, murot gai 무롯지 or murukai 무루깨, bal 발, bigya 비갸, bium 비음, samachi 사마치, chiene 처네, chienui 薦衣 were included in this research can be summarized as follows: It appeared that similar words to dukagai were found in the languages such as the language of the arctic regions, Mongolians, English, Sumerian, and Latin. It is considered that dukgai of Chosun was related to L. toga. The word murot gai or murukai as a kind of head covering had its origins in Korean meaning to cover or to wear. Also it was found that the word bal was derived from L.palla meaning a robe, cloak or mantle. Korean bal 발 meant a dang jugori 당저고리 or dang go ui, a kind of women\`s formal outer dress. It was found that word bium or biim, a garment of Yi Chosun was similar to Ass. birmu, a garment. The word, samachi of Yi Chosun was derived from the Manchurien word samachi meaning a kind of military skirt. The word, chiene 처네 or chienui was derived from the Chinese chien (Equatopms. See Full-text) that means a skirt, a child\`s covering, a sheet, and women\`s underwear.
