In this research, the indium dissolution properties of the waste LCD panel powders were investigated as a function of milling time fabricated by high-energy ball milling (HEBM) process. The particle morphology of waste LCD panel powders changed from sharp and irregular shape of initial cullet to spherical shape with an increase in milling time. The particle size quickly decreased to 15 ${\mu}m$ until the first minute, then decreased gradually about 6 ${\mu}m$ with presence of agglomerated particles after 5 minutes, which increased gradually reaching a uniform size of 13 ${\mu}m$ consist of agglomerated particles after 30 minutes. The glass recovery, after dissolution, was over 99% at initial cullet, which decreased to 90.1 and 78.6% with increasing milling time of 1 and 30 minute respectively, due to a loss in remaining powder of the surface ball and jar, as well as the filter paper. The dissolution amount of indium out of the initial cullet was 208 ppm before milling, turning into 223 ppm for the mechanically milled powder after 1 minute, and nearly 146~125 ppm with further increase in milling time because of the reaction surface decrease of powders due to agglomeration. With this process, maximum dissolving indium amount (223 ppm) could be achieved at a particle size of 15 ${\mu}m$ with 1 minute of milling.

Background: In Korea, Trichophyton (T.) rubrum is occupied more than 80% of causative fungi of dermatophytosis. Strain differentiation of T. rubrum is essential for epidermiologic study. Objective: The aim of this study is to develope the primers for amplification of rDNA intergenic spacer(IGS) to detect polymorphism of T. rubrum. Methods: The primers were designed from 25S and 18S of rDNA, and were applied to 20 strains of T. rubrum, which included 1 standard strain and 19 clinical isolates. Results: Primers for amplification of polymorphic rDNA IGS were designed from the 3’end of the 25S(primer ANID25-3, 5’-GACAGGTTAGTTTTACCCTACTGA-3’) and the 5’end of the 18S (TR18-2R, 5’-ATCTAATAAATACACCCCTTCCGA-3’). PCR condition was adjusted for detecting polymorphism. Best results were obtained at 55℃ for annealing temperature and 3 minutes for extension time. Eight bands sized as 1.1, 2.4, 2.7, 2.9, 3.2, 3.8, 5 kb were amplified with PCR using the primers. With 4 bands sized 2.7, 2.9, 3.2 and 3.8 kb, 20 strains of T. rubrum could be grouped into 6 subtypes. Conclusion: The PCR fingerprinting with the primers for rDNA IGS was able to differentiated strains of T. rubrum, and it can be applied in clinical and epidemiologic studies. The primer could be applied to other fungi with unknown sequences.
