Ewha Womans University is a private women's university in central Seoul, South Korea founded in 1886 by the American Methodist Episcopal missionary Mary F. Scranton. It is currently the world's largest female educational institute and is one of the most prestigious universities in South Korea.While the lack of an apostrophe in "Womans University" is unconventional, the use of "Woman's" rather than "Women's" was normal in the past.Τhe use of "Womans" carries special meaning. The early founders of the college thought that every woman in this community is worth being respected; to promote this idea, they chose the word "woman" to avoid lumping students together under the word "women."

The present disclosure provides a vehicle controller area network (CAN) communication attack detection method and apparatus. The apparatus includes: a learning module, a profiling module, and a detection module. The learning module identifies a CAN identifier (ID) upon receiving a predefined CAN packet and generates learning statistical information expressed as bits with respect to a data field corresponding to the identified CAN ID. The profiling module maintains the learning statistical information received and a precollected attack type, and the detection module extracts a CAN ID and a bit stream of a data field from a real-time input CAN packet. In addition, the detection module configures a neural network by acquiring the learning statistical information from the profiling module, inputs the extracted bit stream to the configured neural network, and determines whether attack is detected, based on an output value of the neural network.

The present invention relates to a respirator without breathing resistance, which has an air inlet duct that passes through an inside and an outside of the respirator and that has asymmetrical electrodes and particle capturing plates formed on an inner surface of the air inlet duct; ozone removing element that removes ozone generated by micro-plasma; and high voltage dc-dc converter that provides high voltage to the asymmetrical electrodes. It employs asymmetrical electrodes and particle capturing plates to filter air without generating breathing resistance. When the respirator according to the present invention is used, safety of a wearer may be maintained in accordance with an environment and breathing may be smoothly performed even while introduction of pathogenic bacteria, viruses, fungi, spores, fine dust, or the like included in air may be effectively blocked. Accordingly, the respirator may be widely utilized to maintain the safety of the wearer in various environments.

The development of cyclometalated Ir(III) complexes has enabled important breakthroughs in electroluminescence because such complexes permit the efficient population of triplet excited states that give rise to luminescent transitions. The triplet states of Ir(III) complexes are advantageous over those of other transition metal complexes in that their electronic transitions and charge-transfer characteristics are tunable over wide ranges. These favorable properties suggest that Ir(III) complexes have significant potential in a variety of photofunctions other than electroluminescence. In this critical review, we describe recent photonic applications of novel Ir(III) complexes. Ir(III) complexes have been shown to affect the exciton statistics in the active layers of organic photovoltaic cells, thereby improving the photon-to-current conversion efficiencies. Nonlinear optical applications that take advantage of the strong charge-transfer properties of triplet transitions are also discussed. The tunability of the electrochemical potentials facilitates the development of efficient photocatalysis in the context of water photolysis or organic syntheses. The photoredox reactivities of Ir(III) complexes have been employed in studies of charge migration along DNA chains. The photoinduced cytotoxicity of Ir(III) complexes on live cells suggests that the complexes may be useful in photodynamic therapy. Potential biological applications of the complexes include phosphorescence labeling and sensing. Intriguing platforms based on cyclometalated Ir(III) complexes potentially provide novel protein tagging and ratiometric detection. We envision that future research into the photofunctionality of Ir(iii) complexes will provide important breakthroughs in a variety of photonic applications. © 2012 The Royal Society of Chemistry.

Light up tomorrow: A photochromic material with excellent fatigue resistance, high thermal stability, and quantitative photoswitching can be used as a linear photoswitching material to replace nonlinear optical materials for encoding optical signals. Therefore, information in one light ray can be directly transmitted to another light ray without converting back to the electronic format. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
