  • Bukholderia pyrrocinia CAB08106-4 has an anti-fungal effect on Garlic White Rot caused by Sclereotium cepivorum and Sclereotium sp. It is environmentally friendly microbial product that prevents and controls a variety of phytopathogens including Garlic White Rot caused by Sclereotium cepivorum and Sclereotium sp. The aim of this study was to assess the environmental toxicity using Cyprinus carpio and Daphnia magna. Bukholderia pyrrocinia CAB08106-4 ($1.0{\times}10^9cfu/mL$) was adminatrated to Cyprinus carpio and Daphnia magna according to the toxicity test guideline for peciticide. $LC_{50}$ of Bukholderia pyrrocinia CAB08106-4 is over $6.67{\times}10^4cfu/mL$ in Cyprinus carpio and Daphnia magna and no adverse effect was observed. Based on these results, we concluded that Bukholderia pyrrocinia CAB08106-4 has no toxiciy for Cyprinus carpio and Daphnia magna.

  • We have developed a 2D-3D convertible 7" autostereoscopic mini-monitor with high 3D quality, in which the parallax barrier LCD is attached on the TFTLCD. The excellent optical performance was achieved by design of the ghost free barrier and precise assembly between the barrier layer and the TFT-LCD panel. Our design principle and fabrication technology suppressed 3D cross-talk and improved viewing angle. In this paper, the design and fabrication process of the 3D mini-monitor are described. The evaluation for the 3D performance is also discussed.
