摘要： A process of manufacturing zirconium alloy. The process may be used to make a nuclear fuel guide tube and/or a measuring tube which are main components of a nuclear fuel assembly structure. While a nuclear fuel guide tube and a measuring tube are manufactured by performing three-step cold working, and intermediate and final thermal annealing from a semi-finished TREX shell in the conventional method, the present invention relates to zirconium alloy undergoing two-step cold working, and intermediate and final thermal annealing from a TREX shell, resulting in enhanced strength and corrosion resistance. The present invention may be applied to a nuclear fuel guide tube and a measuring tube used for a nuclear fuel assembly in a light water nuclear reactor because, by the shortened process, high percentage reduction in thickness between processes and an decrease in thermal annealing time may sustain high strength and excellent corrosion resistance, and achieve economy of manufacture by reducing the number of processes.

摘要： An oxide dispersion strengthening (ODS) method of a metallic material using a laser is provided, which includes melting a surface of a metallic matrix placed on a movable stage by irradiating a laser onto the surface (step 1), supplying an oxide dispersion strengthening (ODS) powder at a site of the matrix surface which is melt at step 1 (step 2), and cooling the matrix in which the ODS powder is supplied at step 2 (step 3). Because oxide particles are directly supplied into previously-made sheet or tube matrix, fabrication process is simplified, fabrication cost is reduced, and end product is fabricated efficiently.

摘要： The present invention relates to a composition for promoting memory or learning ability and to a composition for preventing and treating cognitive impairment, which comprise one, two or more plant extracts selected from the group consisting of Artemisia apiaceae extract, Illicium verum extract and Lepidium apefalum extract. The present invention has the effect of inhibiting neural cell damage, especially, neural cells of the basal part of the cerebrum by inhibiting acetylcholinesterase activity and through antioxidative activity (for example, inhibiting the generation of oxidative reactive species) and affinity for an NMDA receptor. The compositions of the present invention may have the effect of not only promoting memory or learning ability by protecting neural cells and preventing damage to neural cells but also of preventing and treating diseases caused by cognitive impairment. In addition, according to the present invention, Lepidium apefalum extract is provided as basic substance for pharmaceuticals or food which has efficacy in promoting memory or learning ability or efficacy for preventing and treating cognitive impairment.
