Abstract: The present invention relates to a novel 4,5-dihydroisoxazolylalkylpiperazine derivatives having selective biological activity at dopamine D3 and D4 receptors represented by the following Formula (1), and its preparation method through reductive amination reaction in the presence of reducing agent, 1

Abstract: The present invention relates to a color type liquid crystal display having a high aperture ratio, comprising a first substrate which has black matrixes of a color filter arranged in a stripe and a second substrate which has black matrixes in a stripe perpendicular to the black matrixes of the color filter. The disclosed has a large alignment margin without deterioration when an upper and a lower substrates of color type STN are assembled each other, thereby increasing an aperture ratio and yield and decreasing power consumption.

Abstract: The present invention relates to Pseudomonas sp. YS-180 having a capability of producing a docosahexaenoic acid and a method for the production of DHA using such a microorganism. Pseudomonas sp. YS-180 was isolated and identified from the intestine of fishes by investigating the morphological, culturing, and physiological characteristics of a strain excellent in a DHA-producing capability. By TLC and GC, Pseudomonas sp. YS-180 according to the present invention was confirmed that it produced the greatest amount of DHA when it was shaking-cultured in a culture containing glucose 2% (w/v), a yeast extract 2% (w/v), and sea water 20%(v/v). Optimal conditions for producing DHA were a pH of 6.0, and a temperature of 20° C. Under these conditions a DHA production was 96.7 mg/L, and a biomass growth was 7.8 g/L.

Abstract: A method for controlling the operation of a power excavator during a land finishing work is disclosed. In the above method, the bucket, arm and swing unit are controlled in response to output signals from a handling signal input means. Meanwhile, the boom is controlled as follows. That is, when a boom handling signal is output from the handling signal input means, the boom is controlled in response to the boom handling signal. However, when the handling signal input means does not output a boom handling signal, the boom is controlled by a geometrical operation of signals output from the boom, arm and bucket sensors and a land finishing angle for calculating reference boom angle data. The reference boom angle data is control-operated to output an automatic boom control signal, thus controlling the boom in order to move the bucket tip on a land with the land finishing angle in response to an arm handling signal output from the handling signal input means.
