  • Object : In this study, the effect of herbal external therapy, aromatherapy, herb medication against atopic dermatitis was investigated. Method : Atopic dermatitis grade and the effect of medication was determined using Kunz type and SCORAD index. Atopic dermatitos lesion was checked by taking pictures Result : The patient's admission SCORAD index was 74.2 but during 32 days admission treatment the patients's symptoms are getting reduced. At last when she discharged, the SCORAD index was 16.1. Conclusion : In this study, herbal external therapy, aromatherapy and herb medication were shown to treat atopic dermatitis effectively by decreasing itching, oozing, crust, dryness, lichenification. It is very possible that external therapy can offer a valuable mode of the treatment of not only atopic dermatitis but also another eczema.

  • Fabrication and electrical and mechanical properties of piezoelectric micro bending actuators (PMBA) using sol-gel-multi-coated thick PZT films and MEMS processes were investigated. PMBA could be used for design and fabrication of micro fluidic devices, for example, micro-pumps, micro dispensers, and so on. PMBA were fabricated using 2 um thick PZT films on Pt (350 nm)/$SiO_2$ (500 nm)/Si ($300\mu\textrm{m}$) substrates and MEMS processes. 7 types of PMBA were fabricated with areas of silicon diaphragms, PZT films and top electrodes. When the sizes of silicon diaphragms, PZT films and Pt top electrodes were reduced from 3000$\times$$1389\mu\textrm{m}$, 4000$\times$$1000\mu\textrm{m}$ and 4000$\times$$900\mu\textrm{m}$ down to 14%, 14% and 11 % of them, respectively, the center displacements of PMBA were decreased from 0.68 um to 0.10 um at 5 Hz and 12 Vpp. So, PMBA with large areas showed larger displacements than PMBA with small areas and experimental results were also good agreement with the plate and shell theory.

  • The syntheses of 9,9'-spiro-9-silabifluorene as well as 1,1-dichloro-1-silafluorene and 1,1-dimethyl-1-silafluorene through the formation of 2,2'-dibromobiphenyl have been emphasized with good yields. Their fluorescence spectra are obtained using photoluminescence spectrometer and assumed to be the precursors of the development of polymers.
