Abstract: The present disclosure provides a needle assembly and a drug injection device including a needle, a cannula into which the needle is inserted, a first holder supporting the needle, a second holder disposed to face one side of the first holder and supporting the cannula, a sleeve accommodating the first holder in an inner space and rotating with respect to the first holder, and an elastic member disposed between the first holder and the sleeve, wherein, when the sleeve is rotated, the elastic member is expanded and the first holder and the second holder are moved to an extended position, and wherein, when the sleeve is further rotated, the elastic member is contracted and only the first holder is returned to an original position.

Abstract: Provided is an electroosmotic pump including a housing including a shaft hole, a membrane disposed between a first space arranged in a direction away from the shaft hole and a second space adjacent to the shaft hole, a first electrode body and a second electrode body arranged at opposite sides based on the membrane, a shaft extending to an outside of the housing through the shaft hole, and a first fluid included in an internal space of the housing.

Abstract: The present invention relates to novel acrylate-type N-methyl E-2-(2-methylphenyl)oxymethyl)-6-methylphenyl-glyoxylamide O-methyl oxime represented by formula (1), its preparation method and its use as fungicides. The compound of the present invention has not only stronger fungicidal effect on plant pathogens at low concentrations but also broader fungicidal spectrum than the conventional fungicides. Especially, because the compound has excellent systemic and curative effect as well as no toxicity, it can be used as an efficacious agricultural fungicide. In addition, the compound of the present invention can be useful as environmental-friendly fungicide capable of causing less environmental pollution fungicide due to its strong fungicidal effect at low concentrations.
