摘要： The present invention relates to a hybrid system for water treatment, desalination, and chemical production. The hybrid system of the present invention includes a photoanode, an anode chamber, an anion exchange membrane, a middle chamber, a cation exchange membrane, a cathode chamber, and a cathode. In the middle chamber, saltwater or seawater is desalinated by photoelectrochemical electrodialysis. Chloride ions are generated during the desalination, transferred to the anode chamber, and activated by the photoanode. In the anode chamber, wastewater is treated by the activated chloride ions. In the cathode chamber, at least one chemical species selected from the group consisting of water, oxygen, and carbon dioxide is reduced by electrons supplied from the photoanode.

摘要： A method and a device for registering three-dimensional data are disclosed. The method for registering three-dimensional data comprises: generating first two-dimensional data by two-dimensionally converting first three-dimensional data indicating a surface of a three-dimensional model of a target, generating second two-dimensional data by two-dimensionally converting second three-dimensional data indicating at least a part of the three-dimensional surface of the target; determining a first matching region in the first two-dimensional data and a second matching region in the second two-dimensional data by matching the second two-dimensional data to the first two-dimensional data; setting, as initial position, a plurality of points of the first three-dimensional data, which correspond to the first matching region and a plurality of points of the second three-dimensional data, which correspond to the second matching region; and registering the first three-dimensional data and the second three-dimensional data using the initial position.

摘要： The present invention provides a method for preparing an implant including preparing a mixed etching composition including hydrogen peroxide and a water-soluble carbonate compound and oxidatively etching an implant made of titanium or a titanium alloy by immersing the same in the etching composition; a titanium or titanium alloy implant prepared by oxidative etching with a mixed etching composition including hydrogen peroxide and a water-soluble carbonate compound; and a composition for treating surface of an implant containing hydrogen peroxide and a water-soluble carbonate compound. Further, the present invention relates to a titanium or titanium alloy implant which is prepared by oxidative etching with a mixed etching composition including hydrogen peroxide and a basic solution and on which surface bumps having continuous or discontinuous line-shaped open channel structures in nanoscale are irregularly formed, and a preparation method thereof. The surface of the titanium alloys treated with the mixed etching composition including hydrogen peroxide and a carbonate compound or the etching composition containing hydrogen peroxide and a basic solution of the present invention includes micrometer-sized bumps and channel-shaped nanometer-sized bumps, and thus has an increased surface area, and can not only improve wettability, but also effectively promote cell proliferation and osteocyte differentiation. In addition, the composition includes no chemical compounds such as a strong acid, etc. and is thus environmentally friendly, and such compounds can be prevented from remaining on the surface, which can improve biocompatibility, and therefore, the composition can be useful for implant surface treatment.

摘要： The present invention pertains to a novel liposome-based contrast agent that is for suppressing absorption in the reticuloendothelial system and for tumor-specific delivery of a radiolabeled substance. More specifically, the present invention pertains to: a liposome contrast agent containing a lipid and a compound of chemical formula 1, which is a radiolabeled substance, the liposome contrast agent being characterized in that the lipid is composed of (a) cholesterol, (b) 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC), and (c) 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N [methoxy(polyethylene glycol)-2000] (DSPE-PEG2000); and a cancer diagnostic composition containing the liposome contrast agent as an active ingredient. If a liposome system, containing a contrast substance of chemical formula 1 having a unique lipid composition provided by the present invention, is manufactured, the tumor-to-organ uptake ratio of the contrast substance in the reticuloendothelial system increases significantly, thus greatly increasing the tumor diagnostic efficiency of the compound of chemical formula 1.
