Abstract: This application relates to a nickel-based superalloy suitable for additive manufacturing and a method for manufacturing a high-temperature member using the same. The nickel-based superalloy includes 13.7% to 14.3% by weight of Cr, 9.0% to 10.0% by weight of Co, 3.7% to 4.3% by weight of Mo, 2.6% to 3.4% by weight of Ti, 3.7% to 4.3% by weight of W, 2.6% to 3.4% by weight of Al, 0.15% to 0.19% by weight of C, greater than 0% by weight and not less than 0.005% by weight of B, 0.01% to 0.05% by weight of Zr, 2.0% to 2.7% by weight of Ta, 0.6% to 1.1% by weight of Hf, Ni residue, and unavoidable impurities. The nickel-based superalloy has a high fraction of strengthening phase, thereby maintaining excellent high-temperature strength. Additive manufacturing with the nick-based superalloy is much easier than existing nickel-based superalloys, thereby cost-effectively providing maximized cooling efficiency.

Abstract: Techniques for generating and superimposing digital signage onto an immersive view. In an exemplary embodiment, certain entities are occluded or otherwise unviewable in an immersive view of an environment. For such entities, digital signage may be generated and superimposed in a suitable area of the immersive view, and further indicating, e.g., directions to such entities from a viewing location, as well as other metadata, such as business name, website, etc. To determine whether a nearby entity is displayed in the immersive view, a planar layout storing geometrical data associated with entities in the vicinity may be loaded and processed.

Abstract: A security method and system using a server security solution and a network security solution is disclosed. In the security method based on the security system that has a firewall for blocking malicious access to a corresponding network, a network intrusion prevention system for blocking intrusion into the network and server systems including a mail server and a File Transfer Protocol (FTP) server, the server systems transmit information on an intruding system, which has transmitted harmful traffic, to the network intrusion prevention system at the time of detecting the harmful traffic. The network intrusion prevention system blocks the access of the harmful traffic based on the information transmitted from the server systems.

Abstract: A compact lens system is disclosed which includes a first lens group and a second lens group. The first lens group, which has an overall positive refractive power, includes a first meniscus lens, convex toward an object, and having a positive refractive power. Also included is a second biconcave lens having a negative refractive power, and a third biconvex lens which is connected to the second lens and which has a positive refractive power. The first lens group further includes a fourth biconvex lens which has a positive refractive power. The second lens group has an overall negative refractive power, and includes: a fifth concave lens having a positive refractive power; a sixth concave lens having a negative refractive power; and a seventh lens having a negative refractive power. The magnification of the system can be changed by varying a distance between the first and the second lens group in accordance with the following condition:1.1<(f.sub.bT -f.sub.bW)/(L.sub.T -L.sub.W)<1.24where L.sub.
