  • Art Nouveau started from the purpose of making art young by reforming art. Rising in revolt against historical style imitation, Art Nouveau was a movement that demanded modern and trend-fitting styles which were embracing general revolution of life and surrounding environment. In jewelry, new styles were tried to be constructed too, breaking from previous styles. Together with new trial of materials, fine jewelry that technical skills of master craftsmen were emphasized on were shown. Styles of Art Nouveau had been diversely developed, fitting to culture of each country in the whole Europe. They were the bases of styles after the 20th century. Jewelry after Art Nouveau repeated development by being divided into industrial and artistic jewelry. They have influenced on a lot of development until modern times. Art Nouveau led jewelry to the establishment of artistic worth, exceeding the worth of goods. There is a difference between aesthetic jewelry expressed through diverse formativeness of Art Nouveau and modern jewelry designs centered on simple precious jewelry which is biased toward productivity and functionality. Modern times are the times of culture and art that are laying stress on personality and ego-expression and pursue creative and ingenious designs. So, various color expression of Art Nouveau and jewelry styles of diverse materials and motives which were expressed through time period and thought will become examples in leading new design development and design flows of modern jewelry.

  • Purpose: The purpose of this prospective study was to compare the satisfaction levels of the patients worn implant supported mandibular overdentures and conventional complete dentures. Materials and methods: Full edentulous patients (n=40) who were planned to do implant supported mandibular overdentures, aged 51 to 82 years, were enrolled in this study. All subjects rated their satisfaction levels (mastication, pronunciation, esthetics, pain, and general satisfaction) of their original conventional dentures prior to treatment and their new overdentures 1 week and 12 weeks after the delivery on 10 cm visual analogue scales. Repeated-measures ANOVA was performed to compare the satisfaction level of each three period (P<.05). Results: The mean satisfaction levels of the implant supported overdentures after 1 week and 12 weeks of delivery were significantly higher than those of the conventional complete dentures in all scoring parameters (P<.05). After 12 weeks of overdenture delivery, the increase of the satisfaction levels in mastication, pronunciation, and pain and the decrease in esthetics and general satisfaction were observed in comparison with those after 1 week of delivery, however, no significant difference was found between the satisfaction levels of 1 week and 12 weeks after delivery. Conclusion: An implant supported overdenture might be one of the effective ways to give more satisfaction to patients who were not gratified with a conventional denture and eventually to improve their quality of life.

  • This study was carried out to develope an alcoholic drink by fermentation of onion extract using Saccharomyces cerevisiae. The optimal conditions for ethanol production were obtained by standing culture at $25^{\circ}C$ for 5 days with 5% inoculum volume. At the results by flask culture, the growth curve of used S. cerevisiae reached to the stantionary phase at 48 hr and the death phase at 90 hr, whereas ethanol production reached maximum at 114 hr. Under the above conditions, a large scale production was carried out. A standing culture in 5 l fermenter showed the similar results to its flask culture, but progressed 24 hr rapidly more than that of the flask culture. A fed-batch culture was performed by addition of the onionic medium supplemented with 10% (v/v) sucrose after 72 hr from the fermenting start. The fed-batch culture could prevent S. cerevisiae from entering into the death phase and maintain constant level of alcohol production. A continuous culture was able to carry out by adding per every 24 hr the onionic medium supplemented with 10% (v/v) sucrose after 72 hr from the fermenting start. Although S. cerevisiae used showed a little decreased growth, alcohol production maintained roughly the constant level at the maximum yield. To enhance the quality of this alcoholic drink, $2-O-{\alpha}-D-glucopyranosyl$ L-ascorbic acid (AA-2G) was supplemented into the onion extract of the substrate for fermentation. As resulted at this study, this alcoholic drink containing AA-2G should be used as a functional fermented alcohol drink strengthened with vitamin C.

  • The possibility of usage as cosmetic resource of the mycelial culture broth of P. japonica in the mixture of cucumber and grape extracts was investigated. In the effect of collagen synthesis promotion in human fibroblast cells, the culture broth of P. japonica of 0.1, 0.5 and 1.0% concentration increased the amount of collagen synthesis than that of control cells. The culture broth increased the SOD activity in the concentration dependant manner of 0.01% to 1.0% in the antioxydation activity test. About 90% of superoxide radical was eliminated by 0.5% concentration of the culture supernatant in the antioxydation test. Anticoagulant quercetin in the course of mycelial growth in the mixture of cucumber and grape extract was accumulated to 15 folds than that of pre-culture. In the skin safety test of the culture broth, there is no any skin damage signal in the tested 30 people. Taken together, we concluded that the culture broth of P. japonica in the mixture of grape and cucumber extracts can be used as a cosmetic resource.

  • This study investigated the quality characteristics of cookies made with chestnut inner peel powder and its potential as a food ingredient. Cookies were made with various levels (0, 10, 20, 30, 40%) of chestnut inner peel powder. Dough pieces were baked for 20 minutes at $180^{\circ}C$ in an electrically heated rotary oven for about 10 minutes, and all items were measured after cooling for 24 hours at normal temperature. Quality characteristics were measured by moisture content, leavening rate, loss rate, spread factor, color, texture profile analysis, and sensory evaluations. The moisture content of cookies was significantly affected by increasing chestnut inner peel powder (p<0.001). The spread factor as well as L-value and b-value of cookies significantly decreased with increasing chestnut inner peel powder content (p<0.001). However, hardness and redness (a-value) of cookies significantly increased with increasing chestnut inner peel powder content (p<0.001). The sensory score showed that cookies added with 20% chestnut inner peel powder had higher color, texture, and overall acceptability scores than other samples. As a result, quality of cookies added with 20% chestnut inner peel powder was the most suitable, and we suggest that chestnut inner peel is a good ingredient for increasing the consumer acceptability and functionality of cookies.
