Two strains, traditionally referred to as rock flower (Bawhi-kot) and buckwheat flower (Memil-kot or Chile-Kot), were isolated from stored traditional soy sauce and were identified by using the 18S ITS1/4 region sequences. The rock flower strain showed 99% of similarity with Cladosporium sp. and buckwheat flower strain was 99% identical with yeast Sterigmatomyces halophilus. Both strains were tentatively named Cladosporium sp. NK1 and Sterigmatomyces halophilus NK2, respectively. The optimal growth pHs and temperatures of both strains in a YPD broth medium were in the range of pH 5.0 to 7.0 and 22 to $27^{\circ}C$. Both strains were able to grow in more than 20% of NaCl. In the enzyme activity assay, high protease activity of Cladosporium sp. NK1 and S. halophilus NK2 were obtained in YPD containing 10% of NaCl. High amylase activities of both stains were in 15% and 5% of NaCl, respectively. Lipase activity was, however, not detected in both strains.

For every country, the flag is a major symbol that represents the country. Establishing image though the use of the country's symbol is more important for achieving national competitiveness in this global age. In Korea, Taekuki has not been actively applied to fashion products, however Korean people began to realize the Taekuki as a motif of fashion with 2002 World Cup. Thus, research on fashion product development applying Taekuki is needed. This research developed designs for fashion product development applying Taekuki. In addition, through suggesting various applied motives, this research explored the product possibility of global fashion design that represents Korean identity and fashion. For research method, after research on fashion design process, design development was progressed according to the 4-phases that comprehends processes previous researchers presented. First, in the problem recognition phase, background on the introduction of Taekuki to products and Taekuki fashion during 2002 World Cup was analyzed. Then, the need and possibility of fashion product development applying Taekuki's formative characteristics were found. Second, in research and analysis phase, meaning and history of Taekuki as well as flag fashion product developments in the U.S. and England examples were reviewed. Also, individual interviews with experts and consumers were conducted to collect qualitative data regarding product and design direction. Third, in idealization for problem solving phase, 62 designs including 43 apparels and 19 accessories were emerged. Finally, in evaluation phase, 40 university students majoring design evaluated designs' creativity, function, uniqueness, symbol, aesthetics, and harmony. Through this research, it is expected that fashion products applying Taekuki will be formly established as a fashion item. Furthermore, it is also expected that product development in other categories, brand planning, and product development using other national symbols such as name, anthem, and flower will be followed.

In roll forming process, a sheet metal is continuously progressively formed into a product with required cross-section and longitudinal shape, such as a circular tube with required diameter, wall-thickness and straightness, by passing through a series of forming rolls in arranged in tandem. Tn this process, each pair of forming rolls installed in a forming machine play a particular role in making up the required cross-section and longitudinal shape of the product. In recent years, that process is often applied to the bumper rail in the automotive industries. In this study, a optimal Front Bumper Beam manufacturing technology, model deign and proper roll-pass sequences can be suggested by forming number of roll-pass and bending angle. And also effects of the process parameters on the final shape formed by roll forming defects were evaluated.

The activities of flower color biosynthesis-controlling enzymes, flavonoid 3'hydroxy lase (F3'H) and dihydroflavonol 4-reductase (DFR), were analyzed in Llium longijlorum and 11 lily cultivars using biochemical and enzymological methods. Dihydroquercetin (DHQ) product was synthesized by F3'H using dihydrokaempferol (DHK) as a substrate in Lilium longiflorum. F3'H activity was also detected in the eight cultivars tested. The substrate-specific activity of F3'H was observed because eridictiol (ERI), which uses naringenin (NAR) as a substrate, was not detected in the tested cultivars. Leucocyanidin (LCy) product was synthesized by DFR using DHQ as a substrate in Lilium longiflorum. DFR activity was also detected in 'Le Reve', 'Montreux', 'Monte Negro', 'Etude', 'Acapulco', and 'Star Gazer', but not in 'Siberia', 'Royal Race', 'Nove Cento', 'Elite', and 'Cannes'. Substrate-specific activity of DFR was observed because leucopelargonidin (LPg), which uses DHK as a substrate, was not detected in the tested cultivars.

In this study, the brewing and quality characteristics of a variety of honey and yeast strains in Korea were investigated. After fermenting acacia honey, chestnut honey, citrus honey, and mixed flower honey using commercial yeast, the quality changes during fermentation were investigated. Chestnut honey wine (mead) and mixed flower mead showed the highest ethanol contents of 11.9 and 11.3%, respectively after fermenting for 8 days at $25^{\circ}C$. Acacia mead and citron (Chinese lemon) mead showed 5.0 and 8.2% ethanol contents, respectively. Mixed mead, which fermented with acacia honey and mixed flower honey, in order to advance sensory properties, showed the best sensory properties, generating 10.9% ethanol, while another product with citron honey and mixed flower honey generated 11.1% of ethanol but with a lower sensory value. When adding corium peels to the mixed mead of acacia honey and mixed flower honey, the ethanol content was not increased by addition of corium peels into mixed mead, but its total acceptability was increased by addition of 2% corium peels. To check the mead clarification, it was treated with 0.6% of bentonite and filtered; then, its turbidity was observed over a storage period. The safe result for precipitation was shown at the condition of storing at $10^{\circ}C$ for 15 days with 0.24 NTU (Nepthelometric Turbidity Unit).

BACKGROUND: Increased value added by rapeseed (Brassica napus) by-product and the development of a usable rapeseed functional tea. METHODS AND RESULTS: To develop a usable rapeseed functional tea, the total flavonoid content in the varieties Youngsan, Tammi, Tamra, Naehan, Hanra, Mokpo No. 68, and Mokpo No. 111 was investigated. Effect of three treatments, i.e., drying, leaching, and roasting, on flavonoid contents or flower was tested using multiple processing methods per treatment. Total flavonoid content decreased under the various drying methods, confirming that flavonoid content is heat-dependent. This finding was more pronounced for freezing and oven-drying (15.3 and 13.8 mg/g DW, respectively), with a 10% difference in the total flavonoid content between the two methods. Under leaching conditions, the flavonoid content decreased with increasing treatment time. Notably, roasting methods did not result in loss of flavonoid content. The total flavonoid content in the rapeseed varieties decreased in the following order: Youngsan, Tammi, Tamra, Naehan, Hanra, Mokpo No. 68, and Mokpo No. 111. CONCLUSION: The flavonoid content in rapeseed flower was higher in Youngsan than in the other varieties, under processing conditions such as freeze-drying, leaching at $90^{\circ}C$ for 5 min, and roasting.

In the course of screening for antioxidant compounds from natural plants in Korea by measuring the radical scavenging effect, a methanol extract of the flower buds of Daphne genkwa S. et Z. (Thymelaeaceae) was found to show a potent antioxidant activity. Subsequent activity-guided fractionation of methanol extract of D. genkwa led to the isolation of four compounds from the ethyl acetate soluble fraction. The chemical structures were elucidated as genkwanin (1), 3'-hydroxygenkwanin (2), apigenin (3), and tiliroside (4) by spectroscopic techniques. Among them, compound 2 showed the significant anti-oxidative effect on DPPH. And compound 2 showed the significant riboflavin-and xanthine-originated superoxide quenching activities. To verify the antioxidant enzymatic activities of compound 2, the SOD enzymatic activity was measured spectrophtometrically using prepared Caenorhabditis elegans homogenates. The results showed that compound 2 was able to elevate SOD activity of C. elegans in a dose dependent manner. Moreover, compound 2 decreased the intracellular ROS accumulation of worms.

In order to develop a new skin whitening agent, approximately 100 plant extracts were evaluated for their inhibitory activities against melanin biosynthesis in cultured mouse melanocyte melan-a cells. As a result, seven extracts exhibited over 50% inhibition of melanin synthesis compared to control at a concentration of $20\;{\mu}g/ml$. In particular, Aster ageratoides Turcz. var. ageratoides (branch, root, aerial, flower; $IC_{50}$ = 17.3, 6.1, 13.6, $12.9\;{\mu}g/ml$, respectively) and Physalis alkekengi var. francheti (leaf, unripen fructus, aerial; $IC_{50}$ = 6.5, 28.3, $23.9\;{\mu}g/ml$) markedly inhibited melanin synthesis. In addition, tyrosinase activity was monitored by the measurement of dopachrome formation from the oxidation of L-3,4-dihydroxyphenylalanine. Extracts of A. ageratoides Turcz. var. ageratoides (flower) and P. alkekengi var. francheti (leaf) showed the most potent tyrosinase inhibitory activity. These plants might be the potential candidate sources in the development of novel skin-whitening products.

Bracelets have enjoyed extensive use among the Chinese since antiquity as decorative pieces credited with warding off evil forces and inviting auspicious fortune. This study aims to integrate traditional cultural elements, such as Yuan blue and white porcelain flower patterns, into modern design using 3D printing technology to create culturally inspired bracelets. To this end, bracelet designs from the top four museums on Taobao were examined. In addition, we analyzed online reviews of culturally themed bracelets using text mining and applying FEA criteria and found that Chinese consumers are easy to wear and sizable, enhance cultural pride, and drive the demand for artistically sophisticated bracelets. The research culminates in the development of a modular bracelet design inspired by flower motifs from blue and white ware of the Yuan dynasty, with an emphasis on iterative improvements based on reviewer feedback. The final design meets consumers' expressive and aesthetic needs while also maintaining cultural integrity and functionality. The aim of the study is to inspire pride in traditional culture, provide insights for fashion accessory industries, and promote the national image through the development of culturally inspired products.
