  • A cluster of genes for ribostamycin (Rbm) biosynthesis was isolated from Streptomyces ribosidificus ATCC 21294. Sequencing of 31.892 kb of the genomic DNA of S. ribosidificus revealed 26 open reading frames (ORFs) encoding putative Rbm biosynthetic genes as well as resistance and other genes. One of ten putative Rbm biosynthetic genes, rbmA, was expressed in S. lividans TK24, and shown to encode 2-deoxy-scyllo-inosose (DOI) synthase. Acetylation of various aminoglycoside-aminocyclitol (AmAcs) by RbmI confirmed it to be an aminoglycoside 3-N-acetyltransferase. Comparison of the genetic control of ribostamycin and butirosin biosynthesis pointed to a common biosynthetic route for these compounds, despite the considerable differences between them in genetic organization.

  • The study is on the beauty of the line in the Cho-sun Costume. In the aspect of the Costume Aesthetics and Study of Clothing Design, I try to find the beauty of the line in the external form and the immanent beauty of the external line in the Cho-sun Costume. The results of the study is that : 1) The beauty of the line external form have ① the functional beauty of the line ② the beauty of drape line ③ combination of the line of internal and external structure. ④ the beauty of wearing with the Chi-ma. ⑤ the beauty of sharp line in the ornaments 2) The immanent beauty of the line in the Cho-sun Costume : There are a natural beauty found by the reason of nature, temperate beauty, simple beauty in the Cho-sun Costume.

  • The study was performed to compare the raliablity of two Korean version questionaires for respiratory symptoms and ilness being used in Korea. The subjects were 103 dental laboratory technician who divided into two groups as SUN-81-AL and SUN-93. The duration of test-retest was one two month. The differences between two groups interms of average age, height, and weight were negligible. The SUN-93 showed higher agreement compared to SUN-81-AL except items cough and smoking. The Sun-93 deserved to prefer to be used in resporatory epidemiologic study.
