This study evaluated in vitro antioxidant activity, antioxidant content, and ${\alpha}$-glucosidase and pancreatic lipase inhibitory activities of ethanol extracts of samnamul (shoot of Aruncus dioicus), miyeokchwi (Solidago virgaurea), daraesoon (shoot of Actinidia arguta Planchon), and bangpungnamul (leaves of Ledebouriella seseloides), as muknamul, and fresh chamnamul (Pimpinella brachycarpa). Tocopherol content (4.8-78.3 mg/100 g) of sanchae was lower than polyphenols (4.4-12.2 g/100 g). Daraesoon with high tocopherol contents showed high antioxidant activity and ${\alpha}$-glucosidase and pancreatic lipase inhibitory activities. Samnamul had the highest levels of polyphenols and flavonoids, the highest antioxidant activity, and ${\alpha}$-glucosidase inhibition. Antioxidant activity was correlated with flavonoid content ($r^2=0.8895$), but was not correlated with the levels of other antioxidants tested, suggesting that polyphenol content in samnamul, miyeokchwi, daraesoon, bangpung, and chamnamul might not be critical determinant of antioxidant activity. Our results strongly suggest that samnamul and daraesoon could be useful in the treatment of diabetes and obesity.

In this study, the quality characteristics and antioxidant activities of wet noodles added with seunggumcho (Angelica gigas N Leaf) powder at concentrations of 1, 2, 3, and 4%, respectively, were investigated. The moisture contents and pH of the samples showed a tendency to decrease with increasing amounts of seunggumcho powder. Texture measurement indicated that 'hardness,' 'springiness,' and 'chewiness' of the cooked noodle were the highest in the control group, and these parameters showed a tendency to decrease with increasing amounts of seunggumcho powder. The total polyphenol contents in wet noodles added with seunggumcho powder increased with increasing amounts of seunggumcho powder. 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity was the lowest in the control group (10.85%) and highest in the 4% addition group (44.84%). ${\alpha}-Glucosidase$ inhibitory activity showed the lowest value in control group (1.17%), and increased with increasing amounts of seunggumcho powder. The sensory preference score was the highest for color, flavor, taste, and chewiness in the 2% addition sample. The findings of this study suggest the feasibility of seunggumcho added wet noodles as a health food with physiological benefits and provide evidence for introducing various health foods by adding seunggumcho.

The purpose of this study was to compare the coffee shop visits of Koreans and Mongolians, and to determine the quality attributes that should be managed by Importance-Performance Analysis (IPA). The survey was conducted in Seoul and the Gyeonggi Province of Korea, and at Ulaanbaatar in Mongolia from April to May 2012. The questionnaire was distributed to 380 Koreans and 380 Mongolians, with 253 and 250 responses from the Koreans and Mongolians, respectively, used for statistical analyses. From the results, Koreans visited coffee shops more frequently than Mongolians, with both groups mainly visiting a coffee shop with friends. Koreans also spent more time in a coffee shop than Mongolians. In addition, they generally used a coffee shop, regardless of time. In terms of coffee preference, Koreans preferred Americano and Mongolians preferred Espresso. The most frequently stated purpose of Koreans for visiting a coffee shop was to rest, while Mongolians typically visited to drink coffee. The general price range respondents spent on coffee was less than 4~8 thousand won for the Koreans and 2~4 thousand won for the Mongolians. Both Koreans and Mongolians obtained information about coffee shops from recommendations. According to the IPA results of 20 quality attributes of coffee shops, the selection attributes with high importance but low satisfaction were quality, price, and kindness for Koreans, but none of the attributes was found for Mongolians.

Sensory analysis and quality properties were performed on post-aged doenjang (fermented soybean pastes) in order to elucidate the contribution of citrus, green tea and cactus powder to their sensory evaluation. The doenjang added citrus fruits, green tea and cactus powder used a concentration of 0, 3 and 7% (w/w) at 4, 20, $30^{\circ}C$ respectively and analyzed the proximate composition, pH, salt, mineral and amino acid contents after 60 days. Moisture and protein changes during ripening did not show any significant difference. The pH showed lower in the doenjang added citrus and cactus powder than no added soybean paste. The glutamic acid content of doenjang added citrus fruits showed a little decreasing value although there were no differences between samples with various addition contents. Sensory evaluation of doenjang showed that there were no significant differences in preference in the case of added green tea and cactus powder; However, the flavor significantly increased doenjang added 3% citrus powder at $30^{\circ}C$. These results showed that the preference of doenjang containing 3% citrus powder was superior to green tea and cactus powder.

Mistletoes are hemi-parasitic plant growing on different host tree and shrubs. They are traditionally used in folkloric medicine for the treatment of diarrhea, cough, diabetes, hypertension, cancer and skin infection. The purpose of this study was to determine the contents of phenolics and antioxidant activity of 70% ethanol, 100% methanol and hot water extracts of Jeju camellia mistletoe (Korthalsella japonica Engl.). Ethanol was most effective in extracting total phenols (7,427 mg gallic acid equivalent (GAE)/100 g) and flavonoid (1,777 mg rutin equivalent (RE)/100 g). The free radical scavenging activity, 1,1-diphenyl-2-picryl hydrazyl (DPPH) (EC₅₀ = 7.8 mg/ml) and hydrogen peroxide (H₂O₂) (EC₅₀ = 1.4 mg/ml), and the capacity for chelating metal ions (EC₅₀ = 8.0 mg/ml) and reducing power (EC₅₀ = 14.9 mg/ml) of the samples also higher in ethanolic extracts. The strong correlation (r² = −0.996～−0.881) between antioxidant capacities and the phenolic contents implied that phenolic compounds are a major contributor to the antioxidant activity of the ethanolic extracts of Jeju camellia mistletoe. As conclusions, Jeju camellia mistletoe contains bioactive substances with a potential for reducing the physiological as well as oxidative stress and this could explain the suggested cancer preventive effect of these plants as well as their protective role on other major diseases.
