The purpose of this study is to investigate the characteristic analysis and to date guidance of European high heeled shoes in 18th century. The research was conducted by stylistic analysis of high heeled shoes from literature review and museums resource. 14 comparative study on shoe objects dating from 1600-1790 in the Museum at F.I.T., New York, Museum of Art, Boston and Metropolitan Museum of Art, New York were selected. The result of this study are as follows: (1) The origin and development of high heeled shoes were accomplished by protection, social status and exaggeration of body, decoration and fashion. (2) According to the comparative study of Museum objects and literature, characteristic analysis of high heeled shoes from 1700-20s, 1730-40s, 1750-60s, 1770-89 and 1890-1900 were accomplished. (3) Significant elements of European women's shoes from 18th century that aid dating are identified as the presence of white rand, shape of tongue, heel shape and height, latchat, toe shape, color and materials.

Sliding wear mechanism of a high nitrogen austenitic 18Cr-18Mn-2Mo-0.9N steel has been investigated. Dry sliding wear tests of the steel were carried out at various loads of IN-10N under a constant sliding speed condition of 0.15m/s against AISI 52100 bearing steel balls. Solution ($1050^{\circ}C$) and isothermal aging ($900^{\circ}C$) heat treatments were performed on the steel and the effect of the heat treatments on the wear was investigated. Wear rates of the solution-treated steel specimen remained low until 5N load, and then increased abruptly at loads above 5N. The rates of isothermally aged specimens were low and increased gradually with the applied load. Worn surfaces, their cross sections, and wear debris of the steel specimens were examined with a scanning electron microscopy. Phases of the heat-treated specimen and the wear debris were identified using XRD. The transformed phase underneath a sliding track was investigated and analyzed using a TEM. Effects of the phase transformation during the wear and $Cr_{2}N$ precipitates formed during the isothermal aging on the wear of the austenitic steel were discussed.

A polymorphic fungus, Candida albicans, causes various forms of infections such as disseminated candidiasis and vaginitis. Recent reports indicate that the fungus is a main etiological agent for the arthritis. In search of new sources for treatment of the fungal arthritis, we examined $18{\beta}$-glycyrrhetinic acid ($18{\beta}$-GA) against C. albicans-caused septic arthritis. The compound is isolated from Glycyrrhizae Radix that is known to have various immunomodulating activities and is one of the most popular herbal medicines. For induction of animal model of a septic arthritis, mice were given an emulsion form of C. albicans cell wall mixed with Complete Freund's Adjuvant (CFA) via footpad-injection. To determine prophylactic and therapeutic effects, the component was given to the animals before or after the induction of the arthritis, respectively. Data showed that intraperitoneal administration of $18{\beta}$-GA resulted in reduction of the inflammation, indicating the component had both prophylactic and therapeutic activities. For investigation of mechanism of the $18{\beta}$-GA, inhibitory effects on NO (nitiric oxide) and on T-lymphocyte proliferation were determined. Results demonstrated that $18{\beta}$-GA suppressed NO production from LPS (lipopolysaccharide)-treated macrophages and also inhibited proliferation of Con A (concanavalin A)activated T-cells. Taken together, $18{\beta}$-GA, a pentacyclic triterpene, has anti-arthritic activity against C. albicans-caused septic arthritis, possibly by blocking NO production and T-cell suppression.

In this study, we proceed if there are any changes in binding ability of receptor-ligand in some degree of SA and in radioactive uptake from the corpus striatum based on small animal experiment in vivo based on the S.A values. By dividing 18F-Fallypride into 3 S.A values(high S.A : 43.29~74 GBq/umol, ordinary S.A : 20.72~29.23 GBq/umol, low S.A : 6.29~8.51 GBq/umol), we injected directly into the veins and performed 90 minutes of dynamic scan using Micro PET. After scanning, we compared and analyzed with Binding Potential (Binding Potential) from the bilateral striatum. high SA and low SA, ordinary SA and low SA showed significant differences. Also, in the image comparison using 18F-Fallypride show high radioactive uptake in the striatum at high SA and ordinary SA, but the radioactive uptake at low SA is lower than other two SA. Since 18F-Fallypride has affinity to dopamine D2/3 pharmacokinetic, the difference of Binding Potentials at decreased level of SA values was not that significant. However, further PET research of the corpus striatum using 18F-Fallypride is necessary because the differences in images and Binding Potentials at 6.5 times smaller SA values compared to high SA value showed were significant.

The change and development of costume are related to the cultural and socioeconomic factors. In the 18th century the mode of the women's costume in France was greatly influenced by the Rococo style. Elegance and exaggerated ornaments were the major characteristics of the woman's cos-tume in the Rococo period. The high hairdress and the widely hooped panier represented the typical Rococo fashion. From the second half of the 18th century onwards the aristocracy began to lose the battle with the bourgeoisie for political and economic power, and at the same time bourgeoisie fashion exerted an influence on court dress. The court fashion dominated the women's dress fashion in France up to the Revolution. Marie Antoinette, The Queen of Louis XVI, was one of the most influential fashion leaders in the lath century. The fashion, after attaining its highest point in 1770s, changed to a new direction in 1780s under Louis XVI. From that period onward the dimensions were smaller, hairdresses were not so high, and the trimming on the various garments was less liberal. In the mode, exaggeration was replaced by simplicity, and formality was replaced by functionalism.

The evolutionary relationships of the genus Trichoderma and related taxa were assessed using partial sequencing of 18S ribosomal RNA. Phylogenetic tree divided into three major groups; 1. Saccharomyces cerevisiae-Geotrichum klebahnii-Alternaria mali group; 2. Neurospora crassa-Aspergillus-Penicillium-Chrysosporium pannorum-Scopulariopsis sp. group; 3. Trichoderma group. The genus Trichoderma seemed to be phylogenetically separated from Saccharomyces cerevisiae, Aspergillus and Penicillium groups, and have passed through it's own evolutionary pathway.

This essay is focused on finding women's voice in oral narratives of social memory of national violence and resistance. The books of oral narratives of women who had experienced the national violence and participated in the resistance through historic events such as 5.18, have been published recently. This study is based on the materials that have interviewed women experienced the historic event '5.18' in Gwangju. In this study, there are analyses of the materials of the memory of violence and resistance of '5.18', which have contained the texts written by intellectual males and the oral narratives of females directly involved. So far, the memory and experience of women have not been presented in its entirety in the field of social discourse of '5.18'. In the field women's words were translated in men's words, so the real words disappeared and in the end remained unspoken words. And besides, the existence of women are substituted with the limited images (for example women's body destroyed) presented by men's words in memorial materials. In narratives of '5.18', women are reduced to the images of bodies destroyed by national violence. The destroyed bodies are places for exhibition and disclosure of national violence. Women are not presented as the subjects of the social resistance in oral or written narratives of '5.18'. The images of females are only vehicles to urge the male subjects to resist against unjust violence. In this context, men are interpreted for the protectors of sisters, daughters, wives. Since 1980s, the symbol of '5.18 Gwangju' has represented the most ideal community in Korean society. But women have been on the borderline or outside of the community in fact. However, women intend to construct themselves as the subjects of resistance through the spoken words. They have tried to make the politic places for themselves in the social field by speaking and speaking constantly. The desire to speak out is becoming stronger for women, so these days more words are spoken by more women and more oral narratives made by women are revealed in social discoursive field. So the place for women's voice is expanding in social memorial field of '5.18'.

The May 18 Democratic Movement has been considered to be specific case of the big deviation in social memory among the events that occurred after the Korea War. Compared with other events associated with the democratization movement, the May 18 Democratic Movement is special in that can be achieved various changed meaning. In this study, primary focus will be on the background and logics to show what changed the meaning of the May 18 Democratic Movement from the perspectives of the memorial project. And to investigate influences of change of meaning on perspectives and forms of memorial projects. Recognition and forms of memorial projects on the May 18 Democratic Movement had been largely changed around 2000s. Memorial projects were the aspects that are the logics of the social movements absorbed into the logics of the institutionalization before 2000s. During this period, it was done primarily the discourse of a holy ground for democracy and sanctuarization, had characterized the nature of the struggle of memory. After 2000s, the May 18 Democratic Movement has been interpreted historical resources to create a cultural city and a human rights city. Sometimes the May 18 Democratic Movement was appropriated by local development discourse, and sometimes was adopted as the material of differentiation strategy in the city. Form of memorial projects has also been changed type of struggle of memory to type of heritage industry.

We have investigated the solvent effects on $\Delta log\;K_s $(the difference of stability constant of binding) and the different free energies of binding of $Nd^{3+}$ and $Eu^{3+}$ ions to 18-crown-6, i.e., the selectivity of $Nd^{3+}$ and $Eu^{3+}$ ions to 18-crown-6 using a Monte Carlo simulation of statistical perturbation theory (SPT) in diverse solvents. The stability constant ($\Delta log\;K_s $) of binding of $Nd^{3+}$ and $Eu^{3+}$ ions to 18-crown-6, in $CH_3OH$ was calculated in this study as -1.06 agrees well with the different experimental results of -0.44~-0.6, respectively. We have reported here the quantitative solvent-polarity relationships (QSPR) studied on the solvent effects the relative free energies of binding of $Nd^{3+}$ and $Eu^{3+}$ ions to 18-crown-6. From the calculated coefficients of QSPR, we have noted that solvent polarity (ET) and Kamlet -Tafts solvatochromic parameters (b ) dominate the differences in relative solvation Gibbs free energies of $Nd^{3+}$ and $Eu^{3+}$ ions but basicity (Bj) dominates the negative values in differences in the stability constant ($\Delta log\;K_s $) as well as the relative free energies of binding of $Nd^{3+}$ and $Eu^{3+}$ ions to 18-crown-6 and acidity (Aj) dominates the positive values in differences in the stability constant ($\Delta log\;K_s $) as well as the relative free energies of binding of $Nd^{3+}$ and $Eu^{3+}$ ions to 18-crown-6.
