Abstract: A method for coding image information includes generating prediction information by predicting information on a current coding unit, and determining whether the information on the current coding unit is the same as the prediction information. When the information on the current coding unit is the same as the prediction information, a flag indicating that the information on the current coding unit is the same as the prediction information is coded and transmitted. When the information on the current coding unit is not the same as the prediction information, a flag indicating that the information on the current coding unit is not the same as the prediction information and the information on the current coding unit are coded and transmitted.

Abstract: Disclosed are an apparatus and a method for purifying Li7 ions from reactor coolant radioactive material and adjusting pH of the reactor coolant. The apparatus comprises a radioactive metal ion recovery unit comprising a first negative electrode member having a negative (?) electrode connected thereto and a first positive electrode member having a positive (+) electrode connected thereto, and an Li ion separation/concentration unit.

Abstract: The present disclosure relates to a simulation apparatus for secondary battery production.

Abstract: Disclosed is a ball sleeve structure. The ball sleeve structure has convex ball portions and grooves. The convex ball portions are formed at the middle of its outer circumference and are tightly coupled within a ball race in a housing of a variety of joints. The grooves are formed at both sides of its outer circumference and are coupled with sealing boots. The ball portions are formed at regular thickness in the whole portions, by swaging predetermined portions in a hollow tube with holes at the center thereof, such that a metal flow is continuously connected. The ball sleeve structure can be simply and easily manufactured and has excellent strength and reduced amount of material, thereby being capable of achieving a reduction in the manufacturing costs and a reduction in the weight of the product.
