Abstract: The present invention relates to an apparatus for passively preventing a marine floating body from twisting during mooring by controlling tension in ropes connected to the marine floating body within a predetermined allowable limit. The apparatus includes: a floating main body connected to the ropes, fixed on the sea, and providing a space for marine work; winches disposed on the floating main body and retracting or releasing the ropes fixing the floating main body; fairleads disposed on portions of the floating main body and guiding the ropes to the winches through themselves; and braking units disposed on portions of the floating main body at a predetermined distance from the fairleads, with the ropes passing through the fairleads and themselves, and controlling a speed of the ropes that are retracted to the winches at a predetermined speed.

Abstract: A method for detecting a shipwrecked vessel and drown victims by using an aerial hyperspectral image, according to the present invention, comprises the steps of: (a) allowing an image reception unit to receive an observed aerial hyperspectral image, check whether the received aerial hyperspectral image is suitable for detection analysis, and extract observation information, and location information and a reflectance value for each pixel with respect to the detected shipwrecked vessel and drown victims; (b) allowing an image analysis unit to analyze spectral characteristic similarity between a spectral reflection value of a target object and an observed reflection value by using pre-constructed spectral library information and extract constituent materials and an occupation ratio for each pixel of the hyperspectral image, thereby classifying a detection result; and (c) allowing an image visualization unit to display the received hyperspectral image, locations of the detected shipwrecked vessel and drown victims, and detailed information of the detection result.

Abstract: The present invention provides a controller for a pendulum type wave-power generating apparatus. Electric power produced by wave-power generation has been pointed out as being of low efficiency and more expensive than wind-power generation. To overcome the above problems, the present invention uses resonance and impedance matching of the sea waves, thus making it possible to markedly enhance the efficiency of wave-power generation. The present invention does not use a wave-height meter which is generally expensive and controls the generating apparatus in response to variation of the conditions of the sea, thus automatically maintaining the resonance and impedance matching operation, thereby making high-efficiency operation possible. As a result, the cost of the wave-power generation can be reduced, so that the wave-power generation can be widely commercialized.

Abstract: This invention relates to amphiphilic hydrogel particles for antifouling paint, which are environmentally friendly and in which anti-corrosion and antifouling effects can be maximized through a single coating process. The amphiphilic hydrogel particles are fabricated by encapsulating conducting polymer particles having anti-corrosion functionality with functional nanoparticles having antifouling functionality and then immobilizing the functional nanoparticles on a hydrogel matrix, whereby the conducting polymer particles contained in the functional nanoparticles are slowly and continuously released or the release rate thereof can be controlled so as to release the corresponding particles in a specific environment, ultimately maintaining long-term functionality. The conducting polymer particles contained in the amphiphilic functional nanoparticles can exhibit anti-corrosion functionality, thus maximizing anti-corrosion and antifouling effects through a single coating process.
