Vitamin C or L-ascorbic acid, an essential nutrient for humans with antioxidative property, was coated with natural wax to be used as functional additives for cosmetics. Coating of vitamin C was performed using carnauba wax and olive wax in self-designed reaction chamber for 60 min. The yield of coated vitamin C with carnawuba wax and olive wax were up to $94.6{\pm}1.2%$ and $82.5{\pm}1.4%$, respectively. The stability of the carnauba wax-coated vitamin C in the lotion was improved 17.8% than that of uncoated vitamin C during 30 day storage at $25^{\circ}C$. Color and the layer separation of the lotion added with the coated vitamin C showed better property than with the uncoated vitamin C. The coated vitamin C can be applied to cosmetic ingredients as a stable additive.

The author devised a simple technique for duplicating occlusal contour of natural teeth on the prepared abutments using hard stone index obtained from the study cast of natural teeth. Throughout this author devised method, the following advantages are studied. Firstly the dentist can obtain an ideal occlusal wax patterns which have arrived at the physiologic state through a long period of adjustment to various habits and functional movements. Secondly the construction procedure is simple, and thirdly it is easy to adjust wax pattern of nomal natural teeth which duplication is required.

The first function of occlusion is mastication. Therefore the functional restoration of occlusal surface is very important. The restoration of occlusal surface is three method as wax bite technique, F.G.P. technique, cone technique. Many dental technician is using compound method. I am using compound method of wax bite technique and cone technique. I have knew common point on each teeth during I have waxing up wax pattern. So I studied on the design waxup technique for mandible molar occlusion. The results of the study were as follows; 1. The dam wax up method can restore axial contour of teeth very easy and make short working time of wax pattern. 2. The height of dam must be same with cusp of adjacent teeth. 3. Automatically the contour of tooth is appeared if the contour of dam is relationship with cuspid line of adjacent teeth. 4. The height of contour of buccal, lingual surface is formed natural curve to add fluid wax by gravitation. 5. The development groove of mandible first premolar is appeared V form. 6. The development groove of mandible second premolar is appeared Y form. 7, The development groove of mandible first molar is appeared M form. 8. The development groove of mandible second molar is W form. 9. The embrasure is formed to carve around contact point area as round convex. It affects to axial form of tooth. 10. The buccal, lingual groove of molar is formed parallel with direction of teeth arrangement.

Due to high esthetic demands from patients, we are driven to fabricate natural-looking(form and color) restorations. In the past decade, the glass-ceramic in dentistry has been used as a material with variable crystals that affects the appearance, characteristics, and mechanical properties of metal-free fixed restoration. The conventional IPS Empress glass-ceramic is a heat-pressed, leucite reinforced material using the "lost wax" principle. This glass-ceramic has been successfully used for esthetic restorations such as all-ceramic crowns, inlays/onlays, and veneers for about 15 years. This article presents that the form and surface texture of clinical crown are duplicated by IPS-Empress system using "lost-wax technique".

This research has been carried out to examine the effects of quality promoting agents on global quality and epidermal changes of Chamaecereus silvestrii 'Hee-mang' for quality maintenance of the transportation. D-sorbitol than D-mannitol treatment was effective in a lower reduction of fresh weight in C. silvestrii transportations. Application of diniconazole 200 ppm suppressed growth of C. silvestrii. However, it enabled the possibility of long-tenn plant transportation (up to 50 days) and color formation was also effective. As for epidermis structure of C. silvestrii, hypodermis development was lower compared to Gymnocalycium friedrichii and its long-term transportation became poor quality due to single layered, thin cell wall. Application of diniconazole 200 ppm + D-mannitol 10,000 ppm showed higher growth suppressing effects and diniconazole 200 ppm + wax treatment showed better color formation suitable for quality maintenance and storage purposes for C. silvestrii.

The development groove of Maxillary molar is appeared W form. 7. The embrasure is formed to carve around contact point area as round convex. It affects to axial form of tooth. 8. I was knew that the lingual groove and stuart's groove of molar runs parallel with oblique ridge. 9. The buccal groove of molar is formed parallel with direction of teeth arrangement.

Three solvent extraction techniques were used to recover waxy tractions from grain sorghum kernels. Yield and chemical composition of the waxy tractions obtained by reflux, bench scale (recirculated solvent), and countercurrent extraction methods were compared. Waxy traction yield from countercurrent extraction (0.200%) was significantly greater (p<0.05) than the yields of wax from both reflux (0.184%) and bench-scale (0.179%) methods. The waxy traction extracted using the bench-scale method showed the greatest relative amount of long-chained (primarily C:28 and C:30) alcohols while the countercurrent-extracted wax showed the greatest relative amount of long-chained fatty acids and fatty aldehydes. Countercurrent extraction removed a higher additive percentage of fatty aldehydes, acids, and alcohols than reflux or bench-scale extraction method.

Policosanol extracted from sugarcane wax is a generic term used for total fatty alcohols obtained from esterification of fatty acids. It has been approved as a health functional food by the Ministry of Food and Drug Safety of Korea in 2006. Policosanol is well-known to aid in lowering blood cholesterol level. Recently, several studies have reported the physiological activities of policosanol, such as anti-inflammatory effects, antioxidant effects, and lowering of the incidence of ageing-related diseases, for example, hypertension, stroke, among others. This review describes the physiological activities of policosanol and its applications in the field of health functional foods.

Out of 60 quarantine insect pests in Korea, 42 species are classified into tephritid fruit flies. Most of these fruit flies are attracted to two natural products, methyl eugenol (ME) or raspberry ketone. Paraffin wax has been devised to formulate these lures. The formulated lures were applied to field test in Taiwan to attract quarantine fruit flies. Wax-ME formulation was installed in Delta trap and could attract 60-80 males of B. dorsalis per day during late August, while a wax formulation of Cue-lure (a methylated compound of raspberry ketone) attracted both B. cucurbitae and B. tau. These wax formulations can be applied to monitor these three quarantine species in Korea.
