Abstract: Provided are a method and system for detecting a bot in a Massive Multiplayer Online Role Playing Game (MMORPG) online and in real time. By analyzing a communication pattern between a client and a server, the bot is detected based on parameters such as data length, inter-arrival time and data length auto correlation. Tests using respective parameters are combined to construct a global decision scheme, and thus more accurate detection results can be obtained. An integrated anti-bot defense system can be built by combining other tests such as a Turing test.

Abstract: The present invention relates to a composition comprising a Ninjurin1 expression or activity inhibitor for the prevention and treatment of inflammatory disease. Ninjurin1 protein is specifically expressed in macrophages around blood vessels, increases cell-cell adhesion and cell-matrix adhesion, increases expressions of Wnt7b (Wingless-type MMTV integration site family, member 7B) and Ang2 (angiopoietin-2), but reduces expression of Ang1 to induce apoptosis of vascular endothelial cells. In addition, Ninjurin1 protein is up-regulated when inflammation is induced and induces iNOS expression as well as increased NO generation. Therefore, the Ninjurin1 protein expression or activation inhibitor can be effectively used as an active ingredient of a composition for the prevention and treatment of inflammatory disease.

Abstract: An accelerator sensor that is mounted on an engine block may be used to detect vibration of a compression ignition engine, and the detected vibration signal is analyzed to determine the combustion timing of the engine. A method for detecting combustion timing may include measuring a block vibration signal generated in a combustion process of an engine, setting up a frequency area that is to be analyzed in the block vibration to divide the frequency area into wavelet scales, executing continuous wavelet transformations of the divided wavelet scales to extract respective result values thereof and to calculate differences between former result values and latter result values, comparing the calculated difference value with a predetermined value to store crank angles of pertinent timing if the calculated difference values exceed the predetermined value, and averaging the stored crank angles to determine combustion timing in a case that all wavelet scales are processed.

Abstract: The present invention provides a flash memory device having a high degree of integration and high performance. The flash memory device has a double/triple gate structure where a channel is formed in a wall-shaped body. The flash memory device has no source/drain regions. In addition, although the flash memory device has the source/drain regions, the source/drain region are formed not to be overlapped with a control electrode. Accordingly, an inversion layer is induced by a fringing field generated from the control electrode, so that cell devices can be electrically connected to each other. The flash memory device includes a charge storage node for storing charges formed under the control electrode, so that miniaturization characteristics of cell device can be improved. According to the present invention, there is proposed a new device capable of improving the miniaturization characteristics of a MOS-based flash memory device and increasing memory capacity.
