This study was carried out to investigate the biological activities, including the total polyphenolic contents, antioxidant activities, and tyrosinase inhibition activities, of various cultivars of unripe peaches (Prunus persica L. Batsch). The results indicate that the total polyphenolic content (gallic acid equivalent mg/g) was the highest in Yumefuji among six-cultivars (Takinosawa Gold, Kawanakawase Hakuto, Madoka, Yumefuji, Nagasawa Hakuho, and Hong Bak) of unripe peaches, whereas it was the lowest in Madoka. Antioxidant effects of unripe peaches were determined in three different in vitro bioassays measuring DPPH radical scavenging, ABTS radical scavenging, and reducing power activity. In the results, antioxidant activity was also higher in Yumefuji than other cultivars. Tyrosinase inhibition activity ranged from 4.65% to 8.58%, and Hong Bak displayed the highest tyrosinase inhibition activity, although the difference was not significant. This study will provide information on antioxidant and tyrosinase inhibition activities for the development of natural compounds as functional cosmetics.

Purpose: The aim of the investigation was to identify the effects of purposeful activities combined with music on upper extremity function, motivation, and mood in acute stroke patients. Methods: For the study, 19 acute stroke inpatients were recruited at a general hospital in Korea. The patients were allocated between an experimental group (n=9) and a control group (n=10). The experimental group performed purposeful activities with their preferred music, and the control group carried out purposeful activities without music. The 2 groups received the treatments 30 min per day, 5 days per week, for 4 weeks. Measurements were taken before and after intervention, including a manual function test (MFT) for measuring upper extremity function, a volitional questionnaire (VQ) for assessing motivation, and the Beck depression inventory (BDI) and Beck anxiety inventory (BAI) for assessing mood. Results: In post-treatment measurement, both groups showed greater MFT, VQ, and BDI scores than in pre-treatment. Significantly greater VQ and BDI changes were represented in the experimental group as compared to the control group. Conclusion: Based on the findings of this study, purposeful activities combined with music have a positive effect on motivation and depression in acute stroke patients.

Purpose: To better understand falls in elderly women, we measured differences in muscle activities of 4 lower extremity muscles (tibialis anterior, soleus, rectus femoris, biceps femoris) based on angle plantar-flexion in elderly women. Methods: Subjects were 15 healthy elderly women. No subjects had musculoskeletal or nervous disorders. EMGs were used to check muscle activity of lower extremity muscles. For statistic analysis, data were expressed as a percentage of maximal voluntary isometric contraction (%MVIC). We measured %MVIC for 5 sec under 4 conditions and did not use data for the first and last second. Muscle activities of the muscles of the lower extremities were measured based on the degree of plantar-flexion of the ankle joint. The 4 conditions corresponded to different degrees of: 0, 10, 20 and 30 degrees. This was done using a 50 cm board for measuring the degrees. Results: The tibialis anterior, soleus, and bicpes femoris showed increasing muscle activity associated with increasing degree of plantar-flexion of the ankle joint. All muscles showed a significant increase in muscle activities in association with increasing degrees. Rectus femoris showed a significant increase in muscle activity for 0 degrees and for the other degrees, but there were no further changes when plantar flexion of the ankle joint was over 10 degrees. Conclusion: Activities of the muscles of the lower extremities except rectus femoris were higher with increasing degree of plantar flexion. High muscle activity may result in muscle fatigue. Thus, increasing degree of plantar flexion may be risk factors of falls in elderly women.

Protective effects of cheonggukjang fermented with 20% red ginseng (RC) were observed in streptozotocin (STZ)-induced diabetic rats by measuring levels of blood glucose, serum lipid profiles, and hepatic reactive oxygen species generating and scavenging enzymc activities. RC diet was prepared by mixing with AIN-76 diet at the final concentration 2%, and it was fed to STZ-induced diabetic rats for 3 weeks. The RC dict was significantly improved body weight, feed efficiency ratio, levels of serum glucose, and serum and hepatic lipids in diabetes. The significantly elevated O type activity of xanthine oxidase in diabetes was also greatly decreased by the RC diet. The treatment of RC showed the improved hepatic glutathione s-transferase activities in the diabetic animals. The present study indicates that cheonggukjang fermented with red ginseng could ameliorate STZ-induccd diabetic symptoms such as aggravated blood glucose levels, serum lipid profiles, and even the conditions of oxidative stress.

The antimicrobial and antioxidative activities were investigated to confirm the utility of wood vinegar. Antimicrobial activity was performed by paper disc method and liquid culture. The growth inhibition was observed in all microbial species at a dose of as low as 25 $\mu$m of wood vinegar by paper disc method. Also, in liquid culture, S. cerevisiae and P. aeruginosa were more inhibited the growth than others in the concentration of $2\%$ (v/v). For measuring of antioxidative activity, wood vinegar was fractionated with acidic, phenolic, basic and neutral fraction; and their antioxidant activities were measured by the radical scavenging effect on DPPH radical. In four fractions, phenolic fraction showed high antioxidative activity.

A general screening test for the expression of antioxidative activity was performed on over 36 cultures belong to yeast isolated from soy sauce, Makkuli, and molasses. Antioxidative activities of yeasts were examined by measuring oxidation such as peroxide value and thiobarbituric acid value in fish oil. Of these cultures, Saccharomyces cerevisiae IFO 2114 were found to have strong antioxidative activity. Saccharomyces rouxii and Torulopsis etchellsii isolated from soy sauce showed the strongest antioxidative activity among yeasts. Pichia ohmerii isolated from Makkuli showed the strongest antioxidative activity and Candida versatilis isolated from molasses showed also relative strong antioxidative activity.

An aqueous extract of oriental herbal composition named Onchengyeum and curcumin, an antioxidant isolated from turmeric (Curcuma Zonga L.) reduced hepatotoxicity induced by carbon tetrachloride ($CCI_4$). Improved liver function was observed by measuring the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), blood urea nitrogen (BUN), creatinine (CRE), total cholesterol (T-CHO), triglyceride (TG), low density lipoprotein cholesterol (LDL-CHO), high density lipoprotein cholesterol (HDL-CHO), total protein (TP), albumin (ALB) and total bilirubin (BIL) in serum. Hepatic parameters monitored were levels of cholesterol (CHO), triglyceride (TG), and malondialdehyde (MDA) and activities of cytochrome P450 (CYP), NADPH-CYP reductase, superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione S-transferase (GST), glutathione reductase (GR), and glutathione peroxidase (GPx). The histopathological examination showed that the treatment of Onchengyeum and curcumin relieved the ballooning degeneration of hepatocytes which had been generated by $CCI_4$. The results suggested that hepatoprotective effects of Onchengyeum and curcumin possibly are due to their promising antioxidative activity.

This paper proposes a model to assess the maturity level of Six Sigma activities. We classify the maturity level into 5 stages: initial, forming, storming, performing and mature stage. To evaluate the maturity level, 10 categories of Six Sigma with 3 factors each are identified: management leadership, belt system, expert training, establishing execution system, compensation, organization, corporate culture, customer focus, project selection, and management of project results. Scoring 277 items in total, the value of each factor is evaluated by weighted average of those items. Maturity level is appraised by rating the sum of scores of 10 categories that are obtained by summing up the values of its 3 factors. Values of weights and criteria of rating maturity levels are determined by analyzing 90 companies and Six Sigma exper's opinion. This study also shows the actual appraisal results of some companies.

The role of emotional responses is an important subject of study in consumer behavior. Although the perceived performance and satisfaction related emotions have been studied with increasing quantities in leisure studies or fields of outdoor recreation and tourism, issues concerning the appropriate way to measure these emotional responses remains unresolved. This article reviews the emotion measuring scales, and testify the usefulness of PAD scale based upon 349 questionnaires by users of Phoenix Park(Ski Resort) and Seoul Land(Theme Park) in Korea. It was found that, users' emotional response was closely related with satisfaction in Phoenix Park(Ski Resort); however, users' perceived performance was closely related with satisfaction in Seoul Land (Theme Park). This article argues that the meanings of these findings is due to different characteristics of consumption typology between ski resort and theme park. In conclusion, users' emotional experience may be more useful in understanding skiing activities and in formulating management strategies for ski resorts than theme parks.

This study was carried out to investigate the biological activities of star anise extracts obtained from four different solvents (water, methanol, ethanol and chloroform) by measuring total polyphenol and flavonoid contents, DPPH radical scavenging, hydroxyl radical scavenging, nitrite scavenging activity and antimicrobial activity. The methanol extract showed the highest extraction yield, followed by ethanol, water and chloroform. The properties of the extracting solvents significantly affected the total polyphenol content. Methanol extracts contained more total polyphenols than any other extracts. The highest DPPH radical scavenging activity was found in methanol extract. The hydroxyl radical and nitrite scavenging activity were highest in methanol and ethanol extracts. In antimicrobial activity, water extract showed stronger activities than methanol and ethanol extract against Micrococcus luteus and Bacillus subtilis, and no inhibitory effects on Gram negative bacteria were found in all extracts at the concentration used.
