This study was aimed to evaluate magnetite`s ability in treating silicate of back grinding wastewater which is generally produced from semiconductor industry, The back grinding wastewater is the super pure water as the water come out of the semiconductor process and includes the partial silicon powder, By using the magnetite, that is the nano particle implying the magnetism in this wastewater, the silicon grain was absorbed and it removed. The optimum dosage of magnetite, pH, mixing intensity and duration time were investigated and the best silicate removal was 97 % at the magnetite dosage of 0.0 16mg/mL the pH range of 2 to 8 respectively. The magnetic force was also important parameter on the silicate removal. The silicate removal was not affected with magnetic force in the sedimentation time of over 10 mm, whereas, the silicate removal increased as magnetic force increased when the sedimentation time was below 10 mm.

This study was evaluated in order to look into the influence factor reached to these water fleas when the international kind and domestic species was aimed at and the long time was exposed to the chromium, the effect that it reaches to the water flea rates of growth, reproduction and transformation was examined and the comparison about each water flea. Experiments were carried out for over 21days for Daphnia magna and Daphnia sp. and over 10days for Moina macrocopa with concentration of chromium of 0, 1, 3, 5, 10 ug/L in culture media. In the experimental result all concentrations, the water flea survived. Therefore, the that the chromium reaches to the alive of the water flea effect determined to write the effect. The time required for first birth of water fleas was longer periods were required with increase of chromium in every species. For testing period, the number of transformation of every species was decreased with the increase of chromium. The size of neonates, born from the survived adult water flea was significantly smaller with increase of toxic concentration. Also, the number of water flea produced per day was decreased in the order of Daphnia magna, Daphnia sp. and Moina macrocopa.
Daphnia magna와 Daphnia sp. 및 Moina macrocopa의 니켈(Ni)에 대한 만성독성

This study focused on the estimation of the effect of nickel(Ni) on the chronic ecotoxicity of water fleas. This study evaluated the species, Daphnia magna, Daphnia sp. and Moina macrocopa. During long term exposure to the nickel(Ni) the rates of growth, reproduction and transformation of each species were examined. Tests were carried out for over 21days for Daphnia magna and Daphnia sp. and over 10days for Moina macrocopa with concentrations ranging from 0, 1, 3, 5, 10 ug/L of nickel(Ni) in culture media. The survival rate of all three species decreased as nickel(Ni) increased in concentration. And the time required for initial reproduction of the water fleas was less in Moina macrocopa, followed by Daphnia sp. and Daphnia magna. However, reproduction time increased following higher concentrations of nickel(Ni) for each species. The total number of water fleas produced as well as their transformation rate during the test period also decreased. The size of the neonates was significantly smaller with the increase of toxic concentration. Base on the sensitivity to nickel(Ni) concentration, there are different characterizations of the test species for the toxicity assessment. Therefore, chronic toxicity tests with organisms representing different trophic groups should be supplemented in order to provide adequate level of environmental protection.

We proposed a novel stereo matching method using white auxiliary stripe. Conventional active stereo matching has a difficulty of pattern acquisition under the environment with irregular lighting. In order to solve this problem, we proposed a novel pattern called a white auxiliary stripe. The white auxiliary stripe helps color-based pattern acquisition. The proposed method is compared with conventional method by measuring a stepped sample.
