  • We observed and treated a 18 year old male who hae been diagnosed with plane wart. Even though he had been treated with western surgery(Laser operating), he still com planed of recurrent plane wart, suffusion, itching. We treated him with ambulatory treatment and herb medication preventing from high fat diet. Treated for 80 days, his symptoms were almost disappeared. Recently he's being treated adult Atopic Dermatitis with satisfaction

  • The effects of mask materials and etching solutions on the dimensional accuracy of V-groove were studied for the alignment between optoelectronic devices and optical fibers in optical packaging. PECVD nitride, LPCVD nitride, or thermal oxide($SiO_2$) was used as a mask material. The anisotropic etching solution was KOH(40wt%) or the mixture of KOH and IPA. LPCVB nitride has the best etching selectivity and thermal oxide was etched most rapidly in KOH(40wt%) at $85^{\circ}C$ among the mask materials studied here. The V-groove size enlarged than the designed value. This phenomenon was due to the undercutting benearth the mask layer from the etching toward Si (111) plane. The etch rate of (111) plane wart 0.034 - 0.037 $\mu\textrm{m}$/min in KOH(40wt%). This rate was almost same regardless of mask materials. When IPA added to KOH(40wt%), the etch rate of (100) plane and (111) plane decreased, but etching ratio of (100) to (111) plane increased. Consequently, the undercutting phenomenon due to etching toward (111) plane decreased and the size of V-groove could be controlled more accurately.

  • We report the case of an 18-year-old woman with a 6-year history of widespread facial plane warts that had proved resistant to repeated treatments with laser therapy and imiquimod cream. The patient had recurrent lesions, which subsequently resolved with treatment. We diagnosed the case as heat and blood stasis and qi deficiency damp stagnation. Treatment with herb medication and herbal external wet dressing was initiated. During the 4-month treatment period, the warts resolved gradually. At 4 months follow up, there were no recurrent lesions and no other adverse effects.
