Abstract:
본 발명은 강우량 및 지하수위 변동에 따라 깊이가 변동되는 불포화대를 모사함에 있어서 지반모사장치의 길이가 선택적으로 조절되도록 함과 다양한 지점에서의 유체 유출입 및 특성평가가 가능하도록 함으로써 불포화대의 물리화학적 특성 및 생물학적 특성을 정확하게 평가할 수 있는 불포화대 지반모사장치에 관한 것으로서, 본 발명에 따른 불포화대 지반모사장치는 수직방향을 따라 배열, 결합되어 불포화대를 모사하는 상단 컬럼부, 중단 컬럼부 및 하단 컬럼부를 포함하여 이루어지며, 상기 중단 컬럼부는 복수개의 단위 컬럼으로 구성되며, 중단 컬럼부를 구성하는 단위 컬럼의 개수 조절을 통해 지반모사장치와 불포화대의 길이를 축척상 일치시킬 수 있으며, 각각의 단위 컬럼 내에 불포화대의 깊이 방향에 따른 성상을 반영한 지반을 모사하는 것을 특징으로 한다.
Abstract:
PURPOSE: A micro capsule type robot is provided to achieve improved efficiency of inspection of organ, while allowing for ease of manufacture and assembly. CONSTITUTION: A micro capsule type robot comprises a main body(100); a body movement delay unit(200) constituted by a linear driving device and a blade(220) which opens from the outer surface of the main body by the operation of the body movement delay unit and contacts the inner wall of the organ so as to delay or stop the movement of the main body, wherein the body movement delay unit is mounted on the outer surface of the main body; and a control unit arranged in the main body so as to control the operation of the body movement delay unit.
Abstract:
A method for regeneration of a granular zirconium nano-mesostructure and recovery of phosphorus is provided to regenerate a granular zirconium nano-mesostructure onto which phosphorous contained in water is adsorbed through a physicochemical or electrochemical process, and reuse effluent containing phosphorous in the form of phosphoric acid or potassium phosphate through an electrochemical reaction. A method for regeneration of a granular zirconium nano-mesostructure and recovery of phosphorus comprises the process of reacting a phosphorous-adsorbed granular zirconium nano-mesostructure with an aqueous sodium hydroxide solution, an aqueous sodium chloride solution or a mixture thereof as a desorption solution to desorb the phosphorous adsorbed onto the granular zirconium nano-mesostructure. The method further comprises the process of reacting the phosphorous-desorbed granular zirconium nano-mesostructure with an aqueous magnesium chloride solution to regenerate the concerned granular zirconium nano-mesostructure.
Abstract:
PURPOSE: A model internal organ, a device of reproducing the model internal organ and a method of controlling the same are provided to make it possible to experiment on efficiency of the medical equipment in a laboratory, thereby reducing costs and raising the reliability of the experiment by reproducing the alive internal organ. CONSTITUTION: A device of reproducing a internal organ comprises a model internal organ(20) formed by a plurality of layers which are discs(23) of the internal organ comprising a doughnut-shaped tube(30) with an inflow opening (32) and a controller of the tube to inflow and eliminate a fluid in the inflow opening(32). The model internal organ(20) comprises a main body(21) of the model internal organ with a cavity(22), a tube(30) with a plurality of layers on the cavity(22), and an endothelium(40) attached to the inside of the cavity(22) formed by the tube as layered. The endothelium(40) is comprised of the internal organs of animals.
