Journal of Digital Convergence, volume 11, issue 7, 2013, Pages 173~184
Quantum Information Processing and Communication, based on the physical laws of Quantum mechanics, exploits fundamentally new modes of computation and communication and holds the promise of immense computing power beyond the capabilities of any classical computer. In Quantum Information Processing, replacing bits with qubits, one makes two-state quantum systems that do not possess in general the definite values of 0 or 1 of classical bits, but rather are in a so-called. "coherent superposition", of the two. Full exploitation of this additional freedom implies that new processing devices need to be designed and implemented, and that a large scale quantum computer can in principle be built. New discoveries will enable a range of exciting new possibilities including: greatly improved sensors with potential impact for mineral exploration and improved medical imaging and a revolutionary new computational paradigm that will likely lead to the creation of computing devices capable of efficiently solving problems that cannot be solved on a classical computer. In short, Quantum computing is an economy game changer, with a potential of disrupting entire industries and creating new ones.

Journal of Digital Convergence, volume 11, issue 7, 2013, Pages 201~207
The chirp signaling has been mainly used in radar systems due to its good correlation characteristics, and nowadays it is applied to real time locating system(RTLS). The RTLS with chirp signaling was chosen as a standard such as ISO/IEC 24730-5 and IEEE 802.15.4a. In this paper, the performance of a real time locating system with chirp signaling was evaluated and simulated with relative distance error rates. We considered three cases of S/I = -30[dB], -20[dB], and -10[dB] with Rician factor K=10 and K=20. The performance was enhanced with K factor improvement by 25%, 27% and 50% for respective three cases of S/I. As results, in case of S/I < -20[dB], the minimum signal power is required for performance improvement even though the line of sight component is helpful. And also, in case of S/I
-20[dB], as the line of sight component is stronger the better performance is obtained.

This study has significance in terms of its intent to contribute to the increase in hospital revisits by proposing measures to enhance name awareness through an examination of the relationship between the name awareness of public medical institutions and patients' revisit, and its corresponding influences. The study findings were drawn by employing analysis methods such as frequency analysis, reliability and exploratory factor analysis, t-tests, ANOVA, correlation analysis, and hierarchical multiple regression analysis. The results of the correlation analysis showed statistically significant correlations between all independent variables and the patients' revisit or not. The perception of service quality and the environmental factor of medical treatment increased the explanatory power of independent variables, thereby exhibiting a high correlation with the revisit to medical institutions. The usual image, medical service, and medical treatment environment were revealed to have a positive influence on the patient's intent to revisit. This study could confirm a correlation between the name awareness of medical public institutions and the patients' revisit or not. Consequently, to improve the quality and infrastructure of their medical services, public medical institutions are required to perform studies on measures to increase the revisits of patients by identifying their image, medical services, and treatment environment on a consistent basis.
