  • Clove extract by methanol increased expression of the tyrosinase gene on B16 mouse melanoma cells containing tyrosinase promoter. $10{\mu}g/mL$ and $100{\mu}g/mL$ of the extract showed expression rate of the tyrosinase gene about 138% and 245%, respectively, compared with control. At $500{\mu}g/mL$, expression rate of the extract was impossible to measurement by high cytotoxicity. The solvent fraction of methylene chloride also exhibited highly expression rate as methanol extract. However, the solvent fractions of butyl alcohol and water showed repressive effect on expression of tyrosinase gene at $500{\mu}g/mL$. In MTT assay, cell survival rate of the extract exhibited similar to expression rate of tyrosinase gene. That is, $10{\mu}g/mL$ and $100{\mu}g/mL$ of the extract showed the cell survival rate about 128% and 187%, respectively.

  • The present study aimed to find out the most effective instructional method for illustration to aid the $21^{st}$-century post digital generation learners in their education. Although the literature discusses government-led enactment and revision of educational policy and curriculums and research reports by the Ministry of Education and other government agencies as well as many other research articles deal with futuristic instructional methods, the instructional methods in practice have not fully changed yet. Illustration is a means of visual communication and a subject that best represent 'expressionism' and 'speed' of the post digital generation. The present study exemplifies instructional methods to establish the need for lesson plans that best suit individuality of students and for re-training instructors. Also, the feedback process with students proved that the post digital generation learned Photoshop quickly and improved creativity via image synthesis even in short-term instructions. The present findings can be possibly used as reference data for instructional methods for illustration using digital media that best suits learners of the post digital generation. This being said, further studies should delve into specific instructional methods.

  • The study of the awareness on DM, the degree of satisfaction, and intention of word-of-mouth has found that when the confidence factor is stressed, intention of word-of-mouth is seen to rise, and when the perception factor is placed emphasis on, intention of word-of-mouth is also seen to be on the rise. The 790 questionnaires collected were analyzed by frequency, factor analysis, confidence degree, and regression analysis. This means that the higher the degree of satisfaction by means of the recognition, attention, trust of DM advertisement, the relationship reenforcement of DM advertisement and transmission of information is, the higher intention of word-of-mouth is. Beauty art business is characteristic of visits being connected with sales. The awareness has an effect on the degree satisfaction, and it affects intention of word-of-mouth. Therefore, it is thought that Beauty art business requires systematic, analytic and unique DM advertisement.

  • Activity guided phytochemical examination of the rhizome of Phragmites communis has led to the isolation of two phenolic acids and two lignans. Structures of these compounds were elucidated as methyl gallate (1), ${\rho}$ -hydroxy cinnamic acid (2), (+) -lyoniresinol (3), (+)-lyoniresinol-9'-O-${\beta}$-D-glucopyranoside (4) by comparisons with previously reported spectral data. To investigate the melanogenesis inhibitory effects of these compounds, the melanin level and tyrosinase activity were examined in B16F10 melanoma cell. Each compound inhibited both tyrosinase activity and melanin synthesis compared with positive control, kojic acid and arbutin. These results suggest that the phenolic compounds from Phragmites communis might be developed as a potent skin whitenting cosmeceuticals.

  • Purpose: This study examined the effects of foot-reflexology massage on body weight, lower extremity edema, and serum lipids in postpartum women. Method: This study was a nonequivalent control-group pretest-posttest design. Postpartum women were assigned to the experimental group (n=16) or a control group (n=15). Foot reflexology massage was applied 5 times a week, for a total of 2 weeks to the experimental group. The tool for measuring lower extremity edema was the girth of the thigh, and the calf. The measuring tool for serum lipids was total cholesterol and TG in blood serum by clinical process. Data was analyzed by $x^2$-test, t-test, and paired t-test, ANOVA using SPSS/Win PC 14.0. Results: There was a statistically significant decrease in levels of TG in blood serum in the experimental group compared to the control group. Conclusion: Foot reflexology massage is a useful nursing intervention that decreases serum lipids level in postpartum women. Therefore foot reflexology massage is recommended as a nursing intervention strategy for serum lipids reduction in postpartum women.

  • This study examined the correlation between a handle evaluation of cosmetic puff textile and a sensory evaluation. The KES-F system was used to analyze the main mechanical factors for the handle evaluation and a statistical method was used for the sensory evaluation. The results revealed different mechanical properties and handle values of the tested cosmetic puff textiles. A material type and structure of the cosmetic textile affected the handle property of the material which is the most important factor for a cosmetic purpose. Particularly, the physical properties of textile material are likely to be important factors for the sensory property of cosmetic material. In addition, the sensory evaluation also revealed different sensory characteristics of the cosmetic efficiency according to the cosmetic puff textile. No close relationship was observed between the mechanical properties and sensory evaluation on the cosmetic puff textiles. The sensory evaluation of a cosmetic efficiency is not only decided by the physical and mechanical characteristics of the cosmetic textile material. Overall, when using textiles used for the cosmetic purposes, it is important to consider not only the proper mechanical properties of the textiles but also the use and sensory satisfaction. Development and selection of the cosmetic textiles should be focused on both the material function and consumer satisfaction.

  • Cordyceps militaris (CM) occurring from a fruiting body by a host insect is a kind of mushroom, which is composed of animal host and plant fruit body. CM contains large amounts of useful ingredients including polysaccharides, vitamins, amino acids, minerals, etc. The essential amino acids from CM including cystine, lysine, and methionine can be expected to improve damaged hair treatment as effective ingredients. In this study, the improvement effect of the CM extracts on chemical and physical properties for damaged-hair treatment was investigated. The cysteic acid and cystine monooxide produced by oxidation of cystine were analyzed their chemical structure by FT-IR spectroscopy. It was confirmed that the vibration absorption peak ($1,041cm^{-1}$) of cysteic acid was reduced and increased sulfur content considerably which means meaningful improvement effect on damaged-hair treatment. Apparently, the cuticle morphology of the damaged-hair was improved significantly by treatment with CM extracts. Especially, confocal laser scanning microscope images of the damaged-hair treated with the extract showed highly increased fluorescence intensity which means promising effect in hair treatment. The tensile strength of the damaged hair treated also increased by 168% compared with the damaged hair.

  • The ethionine resisconferring gene (ERCI) was constitutively expressed under the control of the alcohol dehydrogenase gene promoter (ADClp) and introduced into the chromosomes of an industrial polyploid strain of Saccharocerevisiae by using the 8-sequences of the Tyl retrotransposon as the recombination site. 8-Integrative cassette devoid of bacterial DNA sequences containing the ampicillin resistance gene was constructed that had the aureobasidin A resistance gene (AURl-C) as the selection marker and ERCl gene. The ERCl gene was also employed as the selection marker in the 8-integrative cassette lacking the A URl-C gene. Industrial Saccerevisiae transformed with these integrative cassettes exhibited strong resistance to DL-ethioncompared with nontransformants.
