This study is concerned with the stability of liquid crystal forming emulsifier with localized depend on change of pH using liquid crystal forming agent of advanced company. The liquid crystal emulsifying agent was localized using Sugar Crystal-LC (bio-tech Co., Ltd., Korea), and comparative samples were measured by using Nikkomulese-LC (Nikko Camicarls, Japan) and Alacel-LC (Croda Camicarls, UK). Liquid crystal formation was confirmed microscopically to show the formation of liquid crystal structure at acidic (pH=4.2), neutral (pH=7.0) and alkaline (pH=11.7). The particles of the liquid crystal were observed with a polarizing microscope according to the stirring speed. The stirring time was all the same for 3 minutes with a homo-mixer, and the stirring speed was increased to 2500 rpm, 3500 rpm and 4500 rpm to observe the liquid crystal state. As a result, it was found that the Korean surfactant was more stable and clear liquid crystal structure was formed than the two foreign acids. In the case of the UK in acid zone, the emulsion particle size was uniform and unstable. In the case of Japanese surfactant, it has similar structure and performance to those of localized Korean. It was found that Korean surfactant had superior emulsifying performance in acid zone compared with foreign products. It is possible to develop various formulations such as liquid crystal cream, lotion, eye cream, etc. using Sugar Crystal-LC emulsifier as an application cosmetic field, and it is expected that it can be widely applied as emulsifying technology for skin care external application in the pharmaceutical industry and the pharmaceutical industry as well as the cosmetics industry.

For the reduction of common-mode noise level in Indirect-contact ECG (IDC-ECG) measurement a driven-right-leg grounding method was a lied to the IDC-ECG. Because the IDC-ECG does not require any direct contact between the electrodes and the human skin. it is adequate for un-constraining long-term ECG measurement at home and its various applications are now under development. However, larger 60 Hz noise induced by power line a ears in IDC-BCG than in conventional ECG, that is a restriction of IDC-ECG a application. In this study, the driven-right-leg ground which has been used in conventional direct-contact ECG, was adapted to the IDC-ECG measurement by feedback of the inversion of amplified common-mode noise to the body through the conductive fertile laid on the chair seat By this study, indirect-contact driven-right-leg ground was developed and it was shown to work stably. It was shown that the level of 60Hz power line noise was reduced to about -40 dB when the driven-right-leg gain was 1000. This study shows that we can extend the upper limit of the frequency band of IDC-ECG to 100Hz from 30Hz which is conventional upper limit in IDC-ECG, and we can raise the ground impedance between the body and conductive textile. So it is expected that the application area of the IDC-ECG will be extended by the results of this study.

Several investigators have reported clinical experience of medial plantar septo-cutaneous flap for reconstruction for soft tissue defect of the hand and digits. Jayme and Hamilton first described the anatomy of superficial branch of medial division of the medial plantar artery used in this flap through cadavaric study in 1997. But, they had a few cases for this flap and there was no anatomic study in Korean. We experienced the reliability of medial plantar septo-cutaneous flap for reconstruction for soft tissue defect of hand and digits through an anatomic study (20 fresh specimens dissected) and clinical application (17 patients). An anatomic study revealed that there were differences in diameter and length of the vessels between Korean and Caucasian. The diameter of vessels in Korean is larger than Caucasian one in each area. Based on this anatomic knowledge, we could harvest this flap safely, and have performed reconstruction on 17 patients with soft tissue defects of hand and digits using a thin, flexible medial plantar septo-cutaneous flap similar to the volar aspect of the hand and digits in anatomical characteristics of the skin and subcutaneous tissue covering. The vessels used for this flap were superficial branches of medial division of the medial plantar artery and vena comitants, or the subcutaneous veins. The mean size of the flap was $2.82cm{\times}4.15cm$. All the flaps survived without significant complications. A medial plantar septo-cutaneous flap possesses several advantages : (1) It is very thin in comparison with other standard free flap; (2) it has two draining venous pathways; (3) it provides a good color and texture match for hand and finger; (4) a good recovery of protective sensation is achievable.

Existing pharmaceutical studies show that Magnolia biondii is effective in treating rhinitis and in reducing cholesterol, given its endogenous, volatile ingredients. The study herein seeks to assess the cosmeceutical activities and anti-inflammatory activities of Magnolia biondii extracts for possible application as cosmetic ingredients. The cosmeceutical and anti-inflammatory activities were investigated using hydroxyl radical scavenging, superoxide dismutase (SOD)-like activity, xanthine oxidase (XO) inhibition, cell viability, nitric oxide (NO) inhibition, and inducible nitric oxide synthase (iNOS) expression by Western blotting. Magnolia biondii extracts were identified to have antioxidant activities in hydroxyl free radical scavenging, SOD-like activity, and XO inhibition. In testing the anti-inflammatory activities of the extracts, NO production was inhibited in a dose-dependent manner. Additionally, in a dose-dependent manner, the Magnolia biondii extracts were able to suppress iNOS expression in LPS-stimulated RAW 264.7 macrophage cells. From these results, Magnolia biondii showed adequate potential for application in cosmetic production and related industries as well as a functional material.

About 18th century in the late Chosun dynasty, various kinds of 'Min-Wha' had played a significant role and had an important meaning in the lives of the people in that period. Therefore, both in material and in technique, so many diversified 'Min-Wha' were mass produced in that time. Starting from those backgrounds, 'Hyuk-Wha', is considered as one of unique style of expression. Though, 'Hyuk-Wha', in techniques, was originated from 'Bibaekseo' classified as one of the style of expression in Oriental drawing and writing art. 'Hyuk-Wha' shows and expresses visual differentiation from rough 'Bibaekseo', in substance, written by brush made from the skin of a willow tree or the stem of a sort of reeds. 'Hyuk-Wha', in mode, has very dose relation to the process of the development of 'Min-Wha'. Judging from this point of view, 'Hyuk-Wha' has deep relationship to Taosmic character painting of 'Gilsang: an auspicious sign' or Confucian character painting of 'Hyojae: filial piety. Accordingly, 'Hyuk-Wha' has been developed to that character painting designed by another type of creative differentiations. For these reasons, 'Hyuk-Wha' which significantly shapes and contains the meanings of Chinese Character also has been esteemed to have interrelation with Pictography in application of Word mark or Brand logotype in graphic areas. 'Hyuk-Wha' which was prevalent in use of home decorations for the people existed in the past has been ceased to exist nowadays in use of home decorations by appearance of all sort of decoration articles. All these days, 'Hyuk-Wha' which was diversified as a part 'Min-Wha' and developed together with oriental drawing and writing art and character painting is to be necessarily relighted. And 'Hyuk-Wha', which is also vigorously in practical application in Western Europe is desirable to be reconsidered.

A common method for treating oral mucosal diseases is taking medication by oral administration. The oral administration is the method of least resistance. Because large part of drugs is degraded by liver, it is necessary to take more drugs getting to appropriate level in blood stream. And there are so many side effects when patients take drugs by oral administration. In so many cases, the patients who suffer from oral mucosal problems have the other general diseases simultaneously. Willingly or not, some patients can't take the medicine by oral administration. Number of topical drugs for oral mucosal disease is less than that for skin diseases because the environment of oral mucosa prevents activity of medicine. In this paper, research on effects of topical type medication for treating oral mucosal diseases is conducted through investigating currently used medications and their effects. In addition, effects of dissolved oral medications with appropriate solvent are demonstrated if this medication is useful for patients clinically.

Previously, studies on compensation material to increase the signal intensity have been conducted which does not affect the reading of images. However, the compensation material has a concern on patient infection as it is attached directly on the skin. Therefore, in this study, we tested an indirect attachment of the compensation material as an alternative method of the direct attachment. The silicon compensation material was fabricated in the form of a cylindrical bar and attached to each element of the 8 channel head coil. Then the signal intensities of the water phantom pre and post application of the silicon were measured. T1 and T2-weighted images were acquired using an 8-channel head coil and a 3.0T superconducting MRI. Signal intensities were measured by using an image measuring program. Paired t-test was used to verify if there were significant differences. The signal intensity before application of the silicon was significantly increased by 3.39% and 2.62% in T1 and T2 weighted images, respectively. Although the indirect attachment method had a limitation to completely replace the existing method, it was considered to be useful in patients with infectious diseases such as diabetic complications since it had a meaningful improvement in signal intensity based on the filling factor increase.

Plum is a climacteric fruit and softening is a serious problem for storage and transportation. Thus $1{\mu}L{\cdot}L^{-1}$ of 1-methylcyclopropene (1-MCP) was applied to plums to prolong their shelf life and maintain quality. Japanese plums (Prunus salicina cv. Formosa) were stored at $20^{\circ}C$ and $0^{\circ}C$ for 14 days and 46 days respectively, with or without 1-MCP treatment. Fruits were treated with $1{\mu}L{\cdot}L^{-1}$ 1-MCP at $10^{\circ}C$ for 24 h. Ethylene production and respiration rate were strongly inhibited in 1-MCP-treated fruits at $20^{\circ}C$. It was also observed that there was less ethanol and acetaldehyde evaporation in 1-MCP-treated fruits stored at $20^{\circ}C$ compared to those in control fruits not treated with 1-MCP. Fruit qualities, such as firmness, titratable acidity (TA), skin color, and decay, changed more slowly in 1-MCP-treated fruits stored at $20^{\circ}C$ than in untreated fruits. There were no differences in the ethylene production or respiration rate between the groups of fruits stored at $0^{\circ}C$ throughout the experiment. Chilling injury was also inhibited by the application of 1-MCP during storage at $0^{\circ}C$. When the fruits stored at $0^{\circ}C$ with or without 1-MCP were transferred to $20^{\circ}C$ after 25 days, the differences in ethylene production and respiration rate, firmness, TA, TSS, and acetaldehyde and ethanol evaporation between the initial (after being stored at $0^{\circ}C$ for 25 days) and the final measurements (after being stored at $0^{\circ}C$ for 25 days and then transferred to $20^{\circ}C$ for three days) were lower in 1-MCP treated fruits than in non-treated fruits. The postharvest application of 1-MCP in Formosa plums showed positive effects at both $0^{\circ}C$ and $20^{\circ}C$ storage conditions with regard to quality, such as low ethylene production and low respiration rates, firmness, TA, ethanol, and acetaldehyde evaporation, chilling injury, and decay.
