Recently, the cosmetics industry considers male customers as a consumptive, active customer base who also have purchasing power with their stronger desire for their personal image enhancement. Male-preferred image brands have entered the era of unlimited competition through social media, thus increasing the acquisition of male beauty. Therefore, the information for designing favorable image strategies should be examined. This paper examines male awareness, determined by the degree of appearance management based on four categories (i.e., hair and skin care, makeup, foot and hand care, and plastic surgery). Based on the research, the paper proposes a data service to address the spatial and temporal separation problem between TV CF (the major media for recognizing information) and online $caf{\acute{e}}$/blog the major media for obtaining detailed information.

Kaempferia galanga L. is one of the plants in Zingiberaceae family. It is used by people in many regions of Asia and Africa for relieving toothache, abdominal pain, muscular swelling and rheumatism. Tyrosinase is a key enzyme for melanogenesis, and hyperpigmentation is associated with abnomal accumulation of melanin pigment. This study aimed to investigate the inhibition of melanogenesis by hexane extract of Kaempferia galanga L. (HKG) in B16F10 melanoma cells. Cell-free tyrosinase, melanin contents, intracellular tyrosinase activity and western blot analysis were performed to elucidate the effects on anti-melanogenesis. Cytotoxicity of the extracts was measured using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and determined the concentration of 12.5, 25 μg/ml. HKG significantly inhibited to activities of intracellular tyrosinase and melanin synthesis in the absence or presence of α-melanocyte stimulating hormone (α-MSH) with dose-dependent manner. And HKG inhibited the expression of tyrosinase, tyrosinase-related protein 1 (TRP-1) and tyrosinase-related protein 2 (TRP-2), regardless of the presence or absence of α-MSH. HKG also down-regulated phosphorylation of p38 and JNK, and up-regulated phosphorylation of Akt. These effects were not related to its cytotoxicity action. These results indicate that HKG has the potential to be a useful therapeutic agent for treating hyperpigmentation disorders and as a beneficial additive in whitening agents in cosmetics industry.

Objective: In the poultry industry, the most important economic traits are meat quality and carcass yield. Thus, many studies were conducted to investigate the regulatory pathways during muscle differentiation. To gain insight of muscle differentiation mechanism during growth period, we identified and validated calcium-related genes which were highly expressed during muscle differentiation through mRNA sequencing analysis. Methods: We conducted next-generation-sequencing (NGS) analysis of mRNA from undifferentiated QM7 cells and differentiated QM7 cells (day 1 to day 3 of differentiation periods). Subsequently, we obtained calcium related genes related to muscle differentiation process and examined the expression patterns by quantitative reverse-transcription polymerase chain reaction (qRT-PCR). Results: Through RNA sequencing analysis, we found that the transcription levels of six genes (troponin C1, slow skeletal and cardiac type [TNNC1], myosin light chain 1 [MYL1], MYL3, phospholamban [PLN], caveolin 3 [CAV3], and calsequestrin 2 [CASQ2]) particularly related to calcium regulation were gradually increased according to days of myotube differentiation. Subsequently, we validated the expression patterns of calcium-related genes in quail myoblasts. These results indicated that TNNC1, MYL1, MYL3, PLN, CAV3, CASQ2 responded to differentiation and growth performance in quail muscle. Conclusion: These results indicated that calcium regulation might play a critical role in muscle differentiation. Thus, these findings suggest that further studies would be warranted to investigate the role of calcium ion in muscle differentiation and could provide a useful biomarker for muscle differentiation and growth.

This research examined the effects of Narcissism as socio-psychological factor and physical features such as BMI on the selfie behavior. The participants of the study were SNS users aged 20-29 years recruited in Daegu and surrounding areas. Statistical analysis including factor analysis, ANOVA, cluster analysis and regression was done using SPSS 23.0 to analyze the results. Two groups with high other-dependent Narcissism showed higher levels of Cosmetic surgery management and clothing management compared to other groups. Among 4 clusters divided by BMI, the lower the BMI, the higher the level of appearance management behavior except for body management. Other-dependent Narcissism and BMI have been shown to have a significant effect on selfie behavior in the relationship of Narcissism, BMI and selfie behavior. In the relationship between appearance management behavior and selfie behavior, only beauty treatment management influenced selfie improvement behavior, and all appearance management behaviors affected selfie complement behavior. Fashion brands should use the relationship between Narcissism, appearance management behavior and selfie behavior in planning selfie related events on SNS as well as consider active collaboration with cosmetics brands. It is necessary to investigate selfie behavior from a more diverse perspective by expanding future research targets and diversify related variables.

There are many synthetic chemicals, such as di(2-ethylhexyl) phthalate (DEHP) and dibutyl phthalate (DBP), used in chemical reaction processes in industry. The establishment of toxicity and detection of synthetic chemicals that may pose a genetic hazard in our enviornment is subjects of great concern at present DEHP, a ubiquitous phthalate plasticizer, induces a wide range of developmental and reproductive toxicities in mammals. DEHP belongs to the large diverse class of peroxisome proliferator compounds, which include herbicides, hypolipidemic drugs. DBP is a plasticizer used to products containing nitrocellulose, polyvinyl acetate, and polyvinyl chloride such as food wraps and blood bags. DBP is also used in cosmetics as a solvent and fixative for perfumes, a suspension agent for solids, an antifoamer, a skin emollient, and hair spray The present study was performed to examine patterns of gene expression in MCF-7 cells following DEHP and DBP exposure. Changes in gene expression were determined by microarray analysis using KISTCHIP-400 including 401 endocrine related genes based on public database and research papers. Of the genes analysis, we determined that genes detected by array showed a 2-fold or greater change in their expression level(increase or decrease). The results of this study demonstrate that a number of genes were differentially expressed in MCF-7 cells but these changes were not significant. Therefore, we keep going this study using microarray analysis and future studies will examine changes of gene expression on time-course and does treatment in variable cell lines.

Obesity is a major risk factor for various metabolic diseases such as cardiovascular disease, hypertension, and type 2 diabetes mellitus. In this study, we prepared ethanol extracts from Agastache rugosa (ARE), Chrysanthemum zawadskii (CZE), Mentha arvensis (MAE), Perilla frutescens (PFE), Leonurus sibiricus (LSE), Gardenia jasminoides (GJE), and Lycopus coreanus (LCE). The anti-oxidant and anti-adipogenic effects were evaluated. The $IC_{50}$ values for ascorbic acid and LCE against 2,2-diphenyl-1-picrylhydrazyl radicals were $246.2{\mu}g/mL$ and $166.2{\mu}g/mL$, respectively, followed by ARE ($186.6{\mu}g/mL$), CZE ($198.6{\mu}g/mL$), MAE ($337.1{\mu}g/mL$), PFE ($415.3{\mu}g/mL$), LSE ($548.2{\mu}g/mL$), and GJE ($626.3{\mu}g/mL$). In non-toxic concentration ranges, CZE had a strong inhibitory effect against 3T3-L1 adipogenes (84.5%) than those of the other extracts. Furthermore, the anti-adipogenic effect of CZE is largely limited in the early stage of adipogenesis, and we revealed that the inhibitory role of CZE in adipogenesis is required for the activation of Wnt signaling. Our results provide scientific evidence that the anti-adipogenic effect of CZE can be applied as an ingredient for the development of functional foods and nutri-cosmetics for obesity prevention.

Free radicals may attack cells or tissue, leading to chronic diseases, and antioxidant consumption is potentially useful for removing free radicals. Egg proteins may be used as potential sources of antioxidant considering their ability of scavenging free radicals to apply for food or cosmetics industry. In this study, we obtained a natural antioxidant protein from fertilized eggs, which was a dietary supplement in some Asian countries. Meanwhile, antioxidant activities of these proteins were evaluated using different oxidation systems. With increasing incubation time, the antioxidant activity of these proteins increased during 15 d of incubation. The samples on day 15 were performed for isolation of antioxidant protein. The protein, named P4-1 (MW, 45 kDa), was isolated and purified by consecutive chromatographic methods. P4-1 contained 17 amino acids, which was determined by liquid chromatography-mass spectrometry and Amino Acid Analyzer. Moreover, the amino acid sequence was highly similar to that of ovalbumin. Differential scanning calorimetry showed that the denaturation temperature of P4-1 was $57.16^{\circ}C$. Furthermore, P4-1 suggested high oxygen radical-absorbance activity in ${\cdot}OH$ assays, and its antioxidant activity was stable at $30-50^{\circ}C$ in acidic and neutral pH. Thus, these results revealed that P4-1 may be a potential resource as a natural antioxidant.

This study described about method that form liquid crystal gel (LCG) by main ingredient with hydrogenated lechin (HL) in OW emulsion system. Result of stability test is as following with most suitable LCG's composition. Composition of LCG is as following. To form liquid crystal, an emulsifier used $4.0\;wt\%$ of cetostearyl alcohol (CA) by $4.0\;wt\%$ of HL as a booster, Moisturizers contained $2\;wt\%$ of glycerin and $3.0\;wt\%$ of 1.3-butylene glycol (1,3-BG). Suitable emollients used $3.0\;wt\%$ of cyclomethicone, $3.0\;wt\%$ of isononyl isononanoate (ININ), $3.0\;wt\%$ of cerpric/carprylic triglycerides (CCTG), $3.0\;wt\%$ of macademia nut oil (MNO) in liquid crystal gel formation. On optimum conditions of LCG formation, the pHs were formed all well under acidity or alkalinity conditions. Considering safety of skin, PH was the most suitable $\pm61.0$ ranges. The stable hardness of LCG formation appeared best in $32\;dyne/cm^2.$ Particle of LCG is forming size of $1{\~}20\;{\mu}m$ um range, and confirmed that the most excellent LCG is formed in $1{\~}6\;{\mu}m$ range. According to result that observe shape of LCG with optical or polarization microscope, LCG could was formed, and confirmed that is forming multi-layer lamellar type structure around the LCG. Moisturizing effect measured clinical test about 20 volunteers. As a result, moisturizing effect of LCG compares to placebo cream was increased $30.6\%$. This could predicted that polyol group is appeared the actual state because is adsorbed much to round liquid crystal droplets to multi-lamellar layer's hydrophilic group. It could predicted that polyol group is vast quantity present phase that appear mixed because is adsorbed to round liquid crystal to multi-lamellar layer's hydrophilic group. This LCG formation theory may contribute greatly in cosmetics and pharmacy industry development.

Vietnam is becoming a leading country in the consumption of Korean wave. Many Vietnamese students have visited Korea due to a significant interest in the Korean wave. This study used focus group interviews with 12 Vietnamese female students in order to examine the experience of the Korean wave acceptance (RQ1), the experience of internalization toward ideal beauty (RQ2) and differences of internalization towards ideal beauty depending on the living period in Korea (RQ3). First, the results of RQ1 showed that Vietnamese students were accepting the Korean wave through media, Korean and social interaction in their daily lives. They also have a positive attitude toward Korean cosmetics and K-pop among various content of the Korean wave. Second, four focal meanings were composed through RQ2. They were the standards of ideal beauty, the causes of ideal beauty internalization and the results of ideal beauty internalization. The results of ideal beauty internalization were separated into the perception dimension and behavior dimension. Last, the results of RQ3 found that the strength of internalization of ideal beauty can very depending on the living period in Korea. This study has academic implications in that it understands Vietnamese female students who become a member of Korean society from a sociocultural perspective. The results of this study are useful to establish practical implications for young Vietnamese consumers to build desirable aesthetic values.
