Since facial skin pigmentation is one of the visual characteristics of skin aging, it is important to evaluate skin pigmentation in the cosmetics and aesthetic fields. Several groups have investigated and developed the image analysis methods for skin pigmentation and some of the groups reported the age-related changes of the number and size of facial pigmented spots. However, they didn't show the changes of the number and size of pigment spots by defined size, and there is no report for Korean female regarding pigmentation. A total of 194 Korean females aged 20 ~ 79 (48.97 ± 17.11 years) were analyzed for the number, size, and intensity of pigmented spots using various filters such as large high-pass filter and median filter in their digital facial images. There were significant correlations between age and total pigmented spot number (No.), size, and intensity (I) (pearson's correlation coefficient r = 0.688, r = 0.645, r = -0.563), and significant correlations were also observed between the number and intensity of pigmented spots of different sizes. According to the ANOVA results, there were significant differences in the percentage of spot size of 2 ~ 4 mm² and > 20 mm² between 20's and 70's. In other words, with aging, pigmentation increases in the facial skin, and the large increase in pigmentation is particularly noticeable in Korean women.

Based on the modifier 'K', the Republic of Korea has been drawing attention from around the world in various fields. Therefore, if you look at a representative field, it can be called the beauty, that is, the cosmetics industry. In particular, paying attention to the fact that interest in appearance has been increasing in recent years, regardless of age or gender, we intend to explore ways to create competitiveness in the industry. In particular, from this perspective, we tried to deal with the company case of AMOREPACIFIC, one of Korea's leading cosmetic companies, and seek the direction of development through analysis of corporate competitiveness. Therefore, as an analysis method for this study, we tried to subdivide and examine the factors that have been possible for a company to succeed using the diamond model of Michael Porter. Based on the factors derived after that, we intend to present the direction for the company to discharge in the future.

Gray hair is a representative sign of aging. Intrinsic aging, stress, and the external environment cause hair graying. Stress is known to be a major factor in the early onset of hair graying. We previously found that Pueraia lobata root extract (PLRE) can prevent hair graying by promoting melanin formation. However, it remains unknown whether PLRE can prevent hair graying induced by conditions of stress. In this study, we confirmed the effect of PLRE on stress-induced hair graying. A reporter cell line was newly constructed to confirm the expression of microphthalamia-associated transcription factor (MITF), the main transcription factor for melanin production. MITF expression and melanin pigmentation were reduced in human hair follicle tissue treated with the stress hormone cortisol or H₂O₂ to induce oxidative stress. PLRE treatment restored MITF expression and increased the amount of melanin pigment in the hair follicle. The expression of Tyrosinase related proteins-2 (TRP-2), a melanin synthesis enzyme in the hair follicle, also increased. In conclusion, PLRE can effectively prevent the inhibition of melanin synthesis by stress hormones and oxidative stress.

It has been reported that the ethanolic extract of the root of Piper methysticum (P. methysticum) inhibits melanogenesis in melanocyte stimulating hormone (MSH)-activated B16 melanoma cells. Flavokawain B (FKB) and Flavokawain C (FKC) isolated from this extract have been found to inhibit melanin production based on anti-melanogenesis activity. This study was designed to find out the inhibition and its process of FKB and FKC on melanin synthesis in melan-a melanocytes. FKB and FKC inhibited melanogenesis at 10 μM, 5 μM respectively in melan-a melanocytes. However, they did not inhibit extracellular tyrosinase activity from melan-a melanocytes. FKB reduced the protein level of tyrosinase (Tyr), tyrosinase-related protein 1 (TRP-1), tyrosinase-related protein 2 (TRP-2), microphthalmia-associated transcription factor (MITF) and the mRNA level of Tyr and TRP-1. FKC reduced the protein level of TRP-2 and MITF and the mRNA level of TRP-1 and Tyr. The reduced expression of Tyr and TRP-1 might be resulted from the decreased MITF which regulates major melanogenic proteins. However, since the mRNA expression of MITF did not change by FKB and FKC treatment, the effects of FKB and FKC on extracellular signal regulating kinase (ERK)/AKT phosphorylation, known to regulate the degradation of MITF, were confirmed. FKB and FKC significantly increased the phosphorylation of ERK1/2, not in AKT. These results suggest that FKB and FKC may be helpful as a potential depigmenting agent for various hyper-pigmentary disorders.

Today the company's brand sites are in tendency locating as a handy method to administrate company vision, value and image. So this study tried to examine the aspects of storytelling around Amore Pacific's brand site. To secure the discussion's centrality and concreteness, two issues are considered to be aimed in methodology. First, the menus of relevant site were examined to see if they are securing minimal narrative. This was an attempt to discuss the minimum narrativity that target text is supposed to possess, to objectify little more the term 'storytelling.' After considering the menus of relevant site through narratological ideas of Gerald Prince, the menus that satisfy the level of minimum narrative were hardly seen. Even 'OUR STORY', showing the intention of unraveling the vision and values within the company brand by stories, is not seemed to be reaching universal, objective storytelling. Second, pragmatic, reception theory were applied as another standard to judge storytelling possibilities of Amore Pacific's brand site. Roger C. Schank's script theory, being considered in the field of cognitive linguistics and cognitive psychology, became a handy tool for examining the interactions and its meaning between brand sites and its visitors. As a result, the relevant site could be seen as attempting storytelling following time sequence, through narrator kindly explaining 'visual image-event.' And it was conjecturable that, because of such function of narrator, visitors finishes storytelling in a personal shape by operating internal story based script. This study examined the level and methods of storytelling limited in online environment called as company brand site. But more studies are needed to be in progress, such as about the ways for company websites or brand sites to have an effective, continuous influence on potential consumers, narrator set-up ways suitable for character of subordinate menus, organizations of minimum narrative and so on.

This paper investigates the asymmetric effect of social sentimental on an individual stock price return. For this purpose, four companies such as POSCO, Korean Electricity, AMORE PACIFIC, KIA Motors are chosen from KOSPI listed companies in terms of dataperspective. The main estimation results are as follows: the positive opinions affect only the stock prices return of three companies while the negative opinions affect all of the companies. It shows that positive or negative texts give asymmetric effect on stock price return and the effect of negative opinions is bigger than that of positive opinions. The results imply that investors are more sensitive to the negatives since they have the tendency of loss aversion. Also, it indicates that subjective opinion on SNS can be used as the proxy for the investment sentiment.
