It is a gel type high functional toothpaste containing vitamin C, E, propolis extract and the rest of herb with a nanoemulsion state. Vitamin C, E is known as the material with an eminent anti-oxidation effect. Propolis is known as the material with an antimicrobial and anti-inflammatory effect. We have been succeeding in making nanoemulsion of vitamin C, E and propolis through the high pressure homogenizer using stable oil and lecithin and the gel type high functional tooth paste were made from nanoemulsion of vitamin C, E and propolis. We observed the process of wound protecting effect and cure effect for a wound of soft tissue, gingival tissue and mucous membrane showing ulcer and inflammation in oral cavity after applying a gel type high functional toothpaste to patient. As a result, the wound were healed very fast and any side effects were not shown. We confirmed that a gel type high functional toothpaste with nanoemulsion of vitamin C, E and propolis extract has good effect not only for wound healing but also for treatment of ulcer-like lesion in oral cavity. So we report our cases with review of literatures.

The design strategy of the multi-functional structure is that the electrical components and the circuits are directly put on their supporting structural panel in which the radiation shields and the thermal control functions are integrated. Applying the multi-functional structure reduces the total mass and size of the space system and makes it possible to lower launch cost. In present study the performance of thermal radiation for six types of multi-functional structure are investigated by the numerical method. The effect of the rib configuration on heat transfer for the multi-functional-structure is not important alone but is meaningful considering with the structural stiffness, difficulty of manufacturing and mass increase. In heat spreading point of view, the thickness of the outer conductive layer is important rather than the rib configuration and the trade-off study with the mass and thickness is required for optimum design.

A surfactant is used to assist the effect of cleaning, dispersibility and adhesion during leather manufacturing process. Existing surfactant for that process includes many hydrophilic groups that may cause problem such as stain, bad water resistance and poor durability, etc. It is potential problem to make high-performance property for future leather market. In this study, we have synthesized the fluorinated surfactant of which property decreases surface tension, increases dispersion, cleaning effect and the better chrome absorption by the high bond energy of C-F to complement weakness that the present alkyl derivative surfactants have. Using fluorinated surfactant, we can confirm that dispersion is increased, chrome absorption ratio is augmented with high osmosis and coherence, chrome content in the tanning waste water is reduced, BOD and COD contents are diminished and physical characteristics are improved.

A new quinoline-based acylhydrazone (1) has been synthesized and applied as a fluorescent probe. Probe 1 exhibits high selectivity and sensitivity to $Cu^{2+}$ with fluorescence "ON-OFF" behavior in HEPES buffered (1‰ DMSO, HEPES 20 mM, pH = 7.4) solution. The on-site generated 1-$Cu^{2+}$ complex displays excellent selectivity to sulfide ions with fluorescence "OFF-ON" performance through copper displacement approach.

The purpose of this study is to offer basic data to manufacture superior girdle, by finding out wearing effect and wearing comfort after select high-functional Girdle and usual girdle on the market, and by analyzing the features of superior girdle in wearing effect and comfort. The results of this research are as follows : 1. As a result of surveying on the wearing feeling of girdle, the tightening effect of high-functional girdle was high. In particular. high-functional long type girdle was excellent as for tightening thigh, but usual girdle was excellent as for general comfortable feeling. In the Questions for comparison and evaluation, the frequency of high-functional long type girdle was highest. 2. As a result of examining the wearing comfort and effect of girdle by each type, the wearing effect of high-functional long type girdle was superior, and the wearing feeling of high-functional long type girdle was higher relatively than that of other types. But, from questions on comfortable feeling, the wearing feeling of usual long type girdle was superior. Generally, the wearing feeling and effect of high-functional long type girdle were superior, since the abdomen was pressed by high-waist type hard material and increased functionality such as attaching treatment to support hip and double treatment to tighten a thigh.
