Many studies in recent decades have revealed that olfactory stimulation by perfume or malodor inhalation exerts various psychological and physiological effects on humans. The most recent studies have examined the electrophysiological response of olfactory stimulation on the activity of human cortical nerve cells. The purpose of this current study is to quantitatively analyze what changes occur in the alpha activity in healthy participants (N=12) on olfactory stimulation using two types of odors (acacia and butanol). Exposure to the odor of acacia perfume was associated with a significant increase (66.7%) in alpha activity when compared with that of the no-odor background EEG. Exposure to the odor of butanol was associated with a significant reduction (33.3% to 41.7%) in EEG alpha activity when compared with that of the no-odor control. The results of this study demonstrated the potential to alter the cerebral cortex activity by olfactory stimulation. The results also suggest that olfactory perception has stimulatory effects on the function of the nervous system. In other words, it could be concluded from this study that inhalation of olfactory stimulation affected brain wave activities and mood states. Further research is needed to completely understand and describe the electrophysiological effects of different odors on the central nervous system.

Shopping information contents shown on online shopping sites represent online retailer's intention to draw potential consumers' visual attention. However, unfortunately, previous studies in literature show that most of the shopping information contents are naively designed just to appeal to consumers' visual attention without systematic and logical analysis of consumers' possible different visual reactions depending on gender. To fill in the research void like this, this study proposes eye-tracking approach to investigating the research issue of how gender affects consumers' visual attention towards human brand image contents on the online shopping sites. For the sake of conducting related eye-tracking experiments, we adopted two types of products - notebook computer as a utilitarian product, and perfume as a hedonic product. Results revealed that female consumers show higher visual attention to human brand image contents than male consumers. Besides, significant gender difference exists on the human brand image contents more highly when they are attached with a hedonic product like perfume, than a utilitarian product like notebook computer. From the eye-tracking-based experiment results like this, this study suggested theoretical backgrounds about gender differences towards online shopping information contents and related human brand image contents as well.

AMOREPACIFIC has rapidly grown to become a successful global brand by persistently seeking and achieving success in foreign markets. In 2011, AMOREPACIFIC was ranked as one of the global top 20 cosmetics companies. What makes AMOREPACIFIC's global success noteworthy is that AMOREPACIFIC challenged the France and the US market, where competition level is the toughest. Lolita Lempicka, AMOREPACIFIC's perfume brand, was chosen as one of the top seven most popular brands in the women's perfume market in France. In addition, Amorepacific, AMOREPACIFIC's namesake skincare brand, is currently recognized as a top prestige brand in the USA. Their success played a significant role as a bridgehead for AMOREPACIFIC in becoming a global cosmetics company. The main object of this case study is to analyze how AMOREPACIFIC became a global cosmetic company through building key brands such as Lolita Lempicka and Amorepafic, among others. Therefore, this study reviewed AMOREPACIFIC's unconventional approach in launching Lolita Lempicka in France, and Amorepacific in the US by focusing on how they foresaw the future opportunities and employed innovative marketing strategies. Specifically, we focused on Amorepacific's marketing strategy under the critical period when AMOREPACIFIC achieved great success in France with Lolita Lempicka (between 1997 and 2004) and in US with the brand, Amorepacific (2003-2008). The case of AMOREPACIFIC's success in the global markets can give valuable lessons to companies that want to extend their businesses to foreign countries and ultimately become global. One such lesson is the importance of building a successful pioneer brand in a powerful bridgehead market. While domestic competitors first entered into less competitive markets such as those in South-East Asia, AMOREPACIFIC challenged the toughest markets such as the French and US markets where the incumbent companies waged the most intensive and severe battles against Lolita Lempick and Amorepacific. Through the success in France and US market, however, AMOREPACIFIC built a powerful base for its successful global expansion. Another valuable lesson is the importance of foresight in uncovering great opportunities hidden behind the trends without losing focus on the brand's core character and values. Lolita Lempicka and Amorepacific showed excellence in foresight competition, which led them to succeed against the intense competition from Goliath companies. If Lolita Lempicka and Amorepacific had just followed the popular market trend at the time, they would have never succeeded.

Determining the elution of water-soluble substances from herbal teas is an important factor in their efficient use in terms of taste, perfume, and content of health-related components. The antioxidant activity and content of catechins in commercial Chrysanthemum indicum (gamguk) teas were determined for optimum elution conditions. The water extract of gamguk teas did not differ significantly in yield compared to methanol extracts and showed stronger antioxidant activity. Catechin contents in gamguk teas were 8-18% of the extracts when individual peaks in high-performance liquid chromatography analysis were compared to standard catechin peaks. Gamguk teas exhibited faster release of antioxidants, and the antioxidant activity was positively correlated with the thermal treatments. Gukhwacha (GC) was the best tea for rapid release (30 sec) of antioxidants with the $50^{\circ}C$ treatment, whereas antioxidants in other teas were relatively slower released.

This study has assessed the anti-oxidative activities and cytotoxic effects of Lithospermum erythrorhizon ethanol extract and measured the effects of tyrosinase inhibition activities with a goal of estimating the usage of the medicinal plant as an ingredient of cosmetics. First, to perform a basic test on the extract, pH and UV-spectrum were measured. According to the measurement, the extract had control functions at pH 5.5, and maximum absorbance occurred at 530nm. In particular, DPPH (1-1-diphenyl-2-picryl-hydrazyl)-inhibiting activity (IC50) and polyphenol content were 149.81 ${\mu}g/mL$ and $51.28{\pm}2.52$ mg/mL respectively. In addition, as extract concentration increased, tyrosinase inhibition activities improved as well. In raw 264.7 cell-based MTT assay, cell survival rates were 98% at 1000 ppm and 153% at 100 ppm. Therefore, it's been confirmed that there is almost no cytotoxin. According to the test results above, it appears that the Lithospermum erythrorhizon ethanol extract would be effective in anti-oxidation and application as a cosmetic ingredient.

This study conducted a survey with 300 male respondents in their 20s to 50s, in order to examine the influence of personal variables, identity of gender roles, self-esteem and social-cultural attitude towards appearance on metro-sexual consumption. The findings are as follows: First, the majority of respondents experienced metro-sexual consumption in passive ways, such as purchasing cosmetics or perfume. Second, self-esteem differed by classification of identity of gender roles and the self-esteem was the most highly rated in non-classified, followed by in femininity, masculinity and androgyny. On the other hand, the non-classified group appeared to have the most highly social and cultural attitude toward appearance. Lastly, when examining the effect of personal variables, identity of gender roles, self- esteem and social-cultural attitude toward appearance on metro-sexual consumption, the results showed that the younger respondents who spend the highest monthly expenses on appearance, belong to the androgynous group and have the social-cultural attitude, are more likely to have a greater tendency towards metro-sexual consumption.
