Objectives : Bambusae Caulis in Liquamen extracts (BE) has been used for various curative effect that remove intense heat from the heart, replenish deficiency Yin, nourish deficiency blood, resolve phlegm. This study was performed to investigate the toxicity of BE to mice according to the administered dosage. Methods : The experimental groups divided four. Control group treated saline, J1 group treated BE and distilled water in the ratio of 1:15(0.05ml/kg), F2 group treated BE and distilled water in the ratio of 1:7(0.05ml/kg), J3 group treated BE and distilled water in the ratio of 1:17(0.05ml/kg). We administered BE to the mice for 24 weeks at interval of 48 hours, and investigated the body weight, changes in hematological profile, activities of the transaminase(GOT, GPT) and two hepatic antioxidant enzyme(SOD, catalase), and histological changes of the liver and kidney. Results : Leukocytes of J3 group were increased in the administered for 12 weeks, but decreased in the administered for 24 weeks. Platelets were decreased about 36% in J3 group treated for 12 weeks, but increased about 50% in the same group treated for 24 weeks. Blood total proteins were decreased slightly in the all experimental groups compared with control group. The activities of the transaminase and superoxide dismutase(SOD) were increased, but decreased activities of catalase in the J2 and J3 groups administered for 12 or 24 weeks. In the light microscopical observation, ballooned and injured hepatocytes in portal vein area of J1 group occurred, and dilated hepatocytes and disoriented sinusoid observed in J2 group administered extracts to mice for 24 weeks. Apoptosis occured in the ballooned and injured hepatocytes of the portal vein area in J3 group. A agglutination of RBC in glomerular capsule of the kidney observed in the J2 group, and destructed convoluted tubule observed in the J3 group treated for 24 weeks. Conclusions : These results indicate that mice treated with high dose BE develop a hematological changes, dysfuncton of the liver and kidney.

The corrosion resistance of Ti-Zr-Pd-Cr alloys were investigated in order to reveal their possible use for new biomedical implant materials. Titanium alloys consisting of 10∼20%Zr, 0.0∼0.4%Pd and 0.15%Cr were prepared by vacuum arc-melting as alloying elements instead of using hardness Al and V in response to recent concerns about the long term safety of Ti-6%Al-4%V ELI alloys. The Ti-Zr-Pd-Cr alloys were heat-treated at 1000℃ for 2hrs under a vacuum atmosphere. The effect of Zr and Pd Ti alloys on the corrosion resistance for biomedical implant was investigating the anodic polarization curve at 37℃ in 5%HCI solution deaerated by high-purity N₂gas bubbling. The critical current density for passivation(I ) of Ti-Zr-Pd-Cr alloys didn't reveal markedly. Passive current density(I ) at 1.0V vs. SCE of this alloys decreased with increasing Zr in the contents from 10 to 20% and decreased with containing Pd in the range from 0.2 to 0.4%. Potential(E ) at 0.1A * m-² of this alloys increased with increasing Zr in the contents from 10 to 20% and increased with containing Pd in the range from 0.2 to 0.4%. For the Co-30%Cr-6%Mo alloy, passivity zone is narrow, and rapid increase of current density result from the low potential in comparison with Ti and Ti alloys. The corrosion resistance by the anodic polarization of Ti-20%Zr-0.2%Pd-0.15%Cr alloy was found to be superior to those of the Ti, Ti-6%Al-4%V alloy and Co-30%Cr-6%Mo alloy. The passive films formed on the Ti-20%Zr-0.2%Pd-0.15%Cr and Ti-6%Al-4%V alloys in the anodic polarization test consist mainly of TiO₂, Ti compound, ZrO₂, Al₂O₃and V₂O₃.

Various types of industry, from manufacturing industry to service industry, can be a subject of exhibition. So, subdivided studies about exhibition for each type of industry or field are necessary. However, there are still insufficient studies about them. Also, fashion industry related exhibitions should be classified differently from other industries' exhibitions because of their special features. Therefore, this study examines that how an exhibition is utilized as a promotion means of a company and the present condition of a fashion exhibition. It also compares a fashion exhibition with other industrial exhibitions to suggest the effective operations and the progressive promotion of the fashion exhibition. This study uses questionnaire from 140 companies for 5 exhibitions, which participated fashion related exhibitions. Data of this study is statistically analyzed using SPSS for window ver. 10.0 program. It also uses frequency, cross tabs, paired t-test, Independent Samples t-test. As a result of this study, fashion related companies' recognition of exhibitions has been increased. However, in terms of exhibition participation, attitudes such as pre-promotion or pre-education for the staff, who are in charge of the exhibition booths, and the outcome of the exhibition aren't maximized because the right under-standing concerning exhibitions is lacking and long-term preparation is insufficient. Also, advertisement for the exhibitions isn't enough because of insufficient preparation and absence of pre-promotion, so consultation with promising buyers can't be activated. Even though there are consultations, the consultations don't have much effect.
