Super-hydrophobic surfaces shows contact angle of water is higher than 140 degrees. That surface can be made several methods such as Carbon nano tubes grown vertically, PDMS asperities arrays, hydrophobic fractal surfaces, and self assembled monolayers coated by CVD and so on. However, we fabricated super-hydrophobic surfaces with plasma etching which is very cost efficient process. Their surfaces are characterized by static contact angles, advancing, receding, and stability against UV irradiations. Optimal surfaces showed static contact angles were higher than 150 degrees. Super-hydrophobic property was remained after UV irradiation for one week.

A case of acute transverse myelitis associated with miliary tuberculosis is presented. A 26-year-old man was admitted to Inju University Paik Hospital because of fever and voiding difficulty. Prior to this 2nd. admission, he was managed under the diagnosis of miliary tuberculosis at our hospital and discharged with improvement. On admission, physical examination revealed normal motor and sensory function, but CSF showed pleocytosis, and managed with anti tbc. durgs under the diagnosis of tbc. meningitis, On 5th hospital day, progressive deterioration of sensory and motor function with decreased DTR on both lower exterimities were observed but CSF study and myelogram were within normal limits. Sensory and motor dysfunction progressively involved to upper spinal cord and finally T5 level was affected. Thereafter, downward recovery of sensory and motor function were observed with voiding control. Upon discharge, he has little voiding difficulty and ambulatory with mild discomfort.
