Lithium has been intercalated into $FeMoO_4Cl$, and deintercalated from $LixFeMoO_4Cl$ both electrochemically and chemically. The inserted $Li^+$ ions are stabilized in the distorted octahedral field in interlayer space of $FeMoO_4Cl$. The crystal symmetry is reduced from tetragonal to monoclinic due to the reduction of ferric to ferrous ions in $LixFeMoO_4Cl$ upon lithium intercalation. From the magnetic and structural data, it has been concluded that the high-spin electronic configuration of $Fe^{2+}(d_{xz}^2{d_{y2}^1}{d_1}{2d_z^12}{\cdot}_y2)$, corresponding to $^5E_g$, group term in $D_{4h}$ symmetry, can be stabilized by the elongation of $FeO_4Cl_{2-}$octahedra in a weak ligand field.

Purpose:?The purpose of this study is to analyze the causal relationship between top management 's leadership and construction quality management activities that affect construction management performance based on construction quality management. Methods:?As its method, the causal relationship between the leadership of top management and the key management factors of construction quality management activities affecting management performance is analyzed by using the structural equation model. The construction companies used in the analysis sample conducted surveys on companies that are conducting ISO, KOSHA, OHSAS, DQC, and so on. Results:?It was revealed that top management's leadership has a great influence on management performance and all management factors of construction quality management activities. However, safety management does not affect the management performance of construction quality management activities. And top management's leadership on management performance are explained by the mediating effect of cost, time, quality and communication among management factors of construction quality management activities. Conclusion:?In the previous study, the quality management activities and the ISO - based integrated total quality management system (TQM) applied in the manufacturing or service industries were presented as empirical results. However, this study presents the results of different studies by presenting empirical study results by selecting time, cost, quality, safety and communication as key management factors of quality management activities of construction companies through reviewing and analyzing previous studies in construction field.

Wireless Transmission Method for VGA Capsule Endoscopy Using Manchester Encoding

조진호,이정현 대한의용생체공학회 2013 Biomedical Engineering Letters (BMEL) Vol.3 No.4

Purpose Recently, technologies related to endoscopes havebeen rapidly developing with the improvements in electronicsand MEMS technology. The human intestine is very longand twisted, and traditional wired endoscopes are able tomonitor the entire intestine except for the small intestine. Toovercome the limited view of wired endoscopes, the capsuleendoscope has been developed. There are some commercialcapsule endoscopes and others under development, but thesecapsule endoscopes have been limited to CIF images, andthe image transmission rate is 2 frames per second. To obtainhigh-quality images, fast wireless communication technologyis needed. Methods In this paper, the direct transmission of distalimages through Manchester code and its receiving algorithmare proposed to obtain endoscope images with higher qualityand faster transmission rate than with conventional capsuleendoscopes. Generally, the baseband signal cannot be radiatedfrom an antenna because of its large bandwidth and lowfrequency band, but the Manchester code can solve theseproblems. To validate the proposed wireless transmissionmethod and its receiving algorithm, computer simulationsand experiments have been performed. Results Experimental results verify that the proposed wirelesstransmission method can transmit VGA-grade images of 640× 480 pixels with a faster frame rate of about 3 frames persecond compared to conventional capsule endoscope methods. Conclusions Therefore, it is expected that the proposed VGA transmission method can be applied to improve theperformance of capsule endoscopes.
