This study examined the quality characteristics of dumpling shells prepared with 0, 2, 4, 6, and 8% mulberry leaf powder. According to the amylograph data, the composite of mulberry leaf powder-wheat flour samples reduced the gelatinization temperatures, viscosities at $95^{\circ}C$, and maximum viscosity with increasing mulberry leaf powder content. The lightness (L) and redness (a) values decreased with increasing mulberry leaf powder content, whereas the yellowness (b) value increased. In addition, the weight, volume, and turbidity increased after cooking. In terms of the textural characteristics, addition of mulberry leaf powder increased the hardness, springiness, cohesiveness, chewiness, and adhesiveness. The DPPH free radical scavenging activity of the dumpling shells increased significantly (p<0.05) with increasing levels of mulberry leaf powder. The taste, chewiness and texture of the dumpling shells prepared with added 4% mulberry leaf powder were preferred. The sensory evaluation showed that the overall preference of the dumpling shell with the addition of 4% mulberry leaf powder was more effective than the control.

Hand eczema is a recurrent and resistant disease that seriously affects the quality of life of patients; currently, there are no ideal treatments for hand eczema. Here, we describe two patients who presented with hand eczema to illustrate the potential efficacy of mesotherapy with snake venom pharmacopuncture (SVP). A 23-year-old woman (Case 1) and a 47-year-old woman (Case 2) presented to the clinic with symptoms of pruritic rash, blisters, and itchiness on both the hands and the left hand, respectively. Both patients were diagnosed with hand eczema based on the physical examination of blisters and redness only on the hands. The patients underwent 1 month (Case 1) and 1 week (Case 2) of mesotherapy with SVP. After treatment, the lesions completely improved and did not recur at 1 year of follow-up. These outcomes suggest that mesotherapy with SVP may be effective for the resolution of hand eczema; however, further research is needed to confirm these findings.

Lentinula edodes mushrooms cultivated under different relative humidities were wrapped at 4℃ and the results of storage characteristics were investigated. Changes in water content of fruiting bodies during the storage period showed the highest water content in fruit bodies harvested from the treatment with the highest relative humidity. The luminosity of the fresh fruiting bodies showed no significant change during the storage period, and the redness was higher in the relative humidity 95% treatment than in the other treatments. According to this study, the relative humidity of the pileus was 65%, and the content of Ergosterol was 0.67 ± 15 g / L at relative humidity of 65%, 80% and 95%. In addition, amino acid analysis and Principal Component Analysis (PCA) confirmed that methionine was the main cause of changes in storage time and relative humidity.

This study attempted to investigate what color would fade more during hair bleaching and examine what should be done to make hair color last longer. For this, hair was colored differently in ash gray with permanent hair dyes and semi-permanent hair dyes each. Hair in multiple levels was created through such bleaching. Color retention was improved in consideration of the degree of color fading in sample hair. In terms of post-bleaching hair coloring, it was more efficient to color hair by eliminating redness without hair damage after shampooing with a permanent hair dye. Therefore, it is anticipated that the study results would be highly useful for beauty salons to find a base level in consideration of bleaching effects and make improve- ments according to hair retention and moisturizing effects.

This study investigated the quality characteristics and antioxidant activities of salad dressing prepared with Jerusalem artichoke powder (0%, 4%, 8%, and 12%). The pH, soluble solid content, and viscosity increased as the content of Jerusalem artichoke powder increased. The titratable acidity showed no significant differences between samples. The lightness values decreased, while the redness and yellowness values increased with increasing amounts of Jerusalem artichoke powder. The total polyphenol content ranged from 52.00-69.64 ㎍ GAE/g, and increased with the increase in Jerusalem artichoke powder levels. The antioxidant activities measured via DPPH and ABTS radical scavenging activity and reducing power also increased with increasing Jerusalem artichoke powder, at a higher rate than in the control. These results suggest that it is beneficial to add Jerusalem artichoke powder when in salad dressing.

This study was conducted to elucidate the relationship between light and coloring and to obtain basic results for promoting redness expression in 'Kalle' (Pyrus communis L.) pear skin. It was investigated in location of anthocyanin layer by microscopic observation and differences in skin color expression of 'Kalle' bagged with paper bag which has different light transmittance rate and inside temperature. However, there was no anthocyanin layer in the brown skin and golden yellow color, anthocyanin layer was distributed in epidermins or hyperdermis of red skin pear and apple. Dark red colored 'Kalle' had more anthocyanin content, $29.8mg{\cdot}100g^{-1}$ FW than light red colored apple 'Hongro'. Light transmittance rate of physical characteristics used paper bags was the highest in white paper bag, 42.2% and it also had more light quantity, $8.9{\mu}mol$ than any other tested paper bags in specific wave length 650-655 nm. The maximum temperature of inner bag was higher about $3^{\circ}C$ in yellow paper bag. The red coloration and anthocyanin contents in no bagged fruits were higher than in any other bagged fruit. However, red color expression among the bagged fruits was higher in white paper bag than in double layered black paper bag and yellow paper bag. Also, chromaticity value seemd to be a good index to explain variation of fruit skin color, because anthocyanin content and chromaticity value were higher. Based on these results, it is desirable to cultivate 'Kalle' without bag for stable redness expression but bagging is essential for decreasing damage by insect in Korea. Further examination to find suitable time of removing paperbag for redness expression and decreasing insect damage. In addition, it is required to develop paperbag whose transmittance rate is high in specific light wavelength or temperature of inner bags is low. Additional key words: anthocyanin, bagging, chromaticity value, light transmittance, Pyrus communis L.

To control populations of the chestnut weevil, Curculio sikkimensis Heller, the effects of various immersion temperatures and times on the chestnut weevil were tested. The effects of immersion treatments on chestnut fruits were also analyzed. The mortality levels of C. sikkimensis larvae were evaluated at various temperatures ($30^{\circ}C$, $35^{\circ}C$, $40^{\circ}C$, $45^{\circ}C$, and $50^{\circ}C$) and time intervals (1, 2, 3, 5, 7, 10, 15, 22, and 24 h). Changes in the chestnut fruit due to the immersion treatment were measured in terms of color (lightness, redness, and yellowness), physiological effects (germination rate and decay rate), hardness, and change in constituent properties (moisture content, free sugar content, and tannin content). Mortality levels of C. sikkimensis larvae after immersion treatment at $30^{\circ}C$ were over 70% and 100% after 2 h and 7 h, respectively. Color (lightness, redness, and yellowness) of the chestnut fruits was not significantly different at $30^{\circ}C$ and $35^{\circ}C;$ however, the color was affected at temperatures over $40^{\circ}C$. The germination rate of the fruit was not affected by the immersion treatments, but the decay rate at $40^{\circ}C$ increased with an increase in immersion time. The hardness of the fruits decreased with an increase in immersion times and temperatures. These results can be used in the future for developing methods for the control of chestnut weevil populations.

We investigated the physico-chemical and sensory characteristics of Kimchi made with red pepper that was washed and mashed. The pH of juice from Kimchi made with red pepper powder was the highest on the day of Kimchi preparation. In the case of Kimchi made with mashed red pepper, the pH of juice and liquid was lower than that of other samples. A similar decrease in pH of juice and liquid was observed up to the second week of fermentation, but the significant difference between both samples wasn't found. The total acidity of Kimchi with mashed red pepper was significantly increased during early fermentation, but was similar during the second week, compared with that of Kimchi with red pepper powder. From the third week of storage, both juice and liquid from Kimchi made with red pepper powder was relatively increased. L and a value of liquid was highest in the case of Kimchi made with mashed red pepper, but b value was lowest during fermentation. In the case of organic acids, acetic acid and lactic acid contents were increased in Kimchi made with mashed red pepper while fermentation progressed. In addition, citric acid content was constant up to the second week in Kimchi made with mashed red pepper but from the third week wasn't detected in both Kimchi made with mashed red pepper and Kimchi made with red pepper powder. In the case of QDA(Quantitative Descriptive Analysis) profiles, the values of Kimchi made with mashed red pepper were significantly higher than those of Kimchi made with red pepper powder in respect to redness, pungency and fresh flavor immediately after the preparation of Kimchi and during the second week of fermentation, but during the fifth week the values were higher in respect to redness and fresh flavor of Kimchi. Appearance and overall acceptability was remarkably increased in Kimchi made with mashed red pepper, compared with that of Kimchi made with red pepper powder immediately after pickling, during the second and the fifth week of fermentation. Therefore, these results indicate that mashed red pepper increased more citric acid content, L and a value of Kimchi in comparison with red pepper powder, resulting in the good effects on overall acceptability due to the significant increase of redness and fresh flavor.
