  • ■ Objectives The purpose of this study was to investigate the correlation of The Korean Standard Pattern Identification for Stroke and Intima-Media Thickness of common carotid artery(CCA-IMT). ■ Methods 100 subjects with acute ischemic stroke were recruited from the patients admitted to DongEui Medical Center from the June 2011 to January 2014. We assessed 100 patient's Common Carotid Intima Media Thickness data by B Mode ultrasonography. We investigated pattern identification of all subjects based on Korean Standard Pattern Identification for Stroke-III. then, We analyzed their characteristics, risk factor, blood test result, life style. ■ Results We analyzed indicators of Korean Standard Pattern Identification for Stroke-III by Common Carotid Intima Media Thickness difference. As a result, pale complexion, look powerless, drowsiness like to lie, heat vexation and aversion to heat were significantly higher in the CCAIMT ≧ 1.0mm group then in the CCA-IMT < 1.0mm group. ■ Conclusion According to the analysis, the Relationship between Carotid Intima-Media Thickness and The Korean Standard Pattern Identification for Stroke in Ischemic Stroke Patients were founded. To acquire more concrete conclusion on this theme, we need more research.

  • Generally, if RGB image is sent to the printer when we print a digital photograph, the printer will convert RGB to CMYK by the inner built-in drive. Because the difference between color domain of RGB and CMYK will cause that change and difference. The most common way to solve the problem is to convert colors by using ICC profile at RIP software or to adapt automatic color converting from the software of the original printer. So we intended to study show which way is most efficient to the digital output and which color mode device is the best based on the printer's own drive in this paper. we tried to observe and check the extended range of color space such as AdobeRGB as well as CMYK and sRGB. Then we made sure which is the suitable color space. Besides, When we convert RGB mode into CMYK mode by utilizing RIP software and adapt the printer's ICC profile made by our selves, we evaluated the output we get and compared the result with extended RGB image. The results are as follows. In case of RGB mode, the printer requests RGB, and that makes the color space more efficient than CMYK's. Converted to CMYK by utilizing RIP software, the chroma is more linearized than the one produced with its' own driver. Compared with sRGB mode's color gamut, AdobeRGB mode's color gamut and CMYK mode's color, CMYK mode's color gamut is the smallest among 3 of them. CMYK mode's color gamut by utilizing RIP software can be changeable. that can be small and narrow or wide and broad. In other words, the volume of color gamut depends on how CMYK is linearized. The color space of sRGB is more advantageous than the one of AdobeRGB in color-reproduction printed. But in the group b, the chroma leaves behind in terms of reproduction, In the group of a, the chroma is excellent relatively. Visual evaluation of the image, AdobeRGB image has not many reproduction colors. Specially, according to printers' characteristics, Group B of AdobeRGB and sRGB color space is a long way behind In terms of reproduction but Group Y is excellent relatively.

  • With the proliferation of nonlinear loads such as personal computers in an educational office building, high neutral harmonic currents have been observed. High neutral currents in three-phase four-wire distribution power systems can cause overloaded neutral conductors, overloaded transformers, voltage distortion, common mode noise, and malfuntion of protective equipment. On-site measurements of harmonic currents and voltages were made and the corresponding equivalent circuits was developed. The circuit model under study was simulated numerically and graphically through the use of the software MATLAB.

  • The number of matched peaks (NMP) is estimated as the spectral similarity measure in tandem mass spectral library searches of small molecules. In the high resolution mode, NMP provides the same reliable identification as in the case of a common dot-product function. Corresponding true positive rates are (94±3) % and (96±3) %, respectively.

  • Leakage phenomena of flip-chip structures on common GaAs and alumina main substrates are characterized using the spectral domain approach to reduce the possible chip-to-chip crosstald and transmission resonance. We have found taht the longitudinal section magnetic mode is dominant for the coplanar waveguide leakage andthe leakage can be suppreassed by properly managing the gap height and the main substrate thickness in addition to the dielectric constant. These calculation results will be helpful for designing and flip-chip packagaing of high-frequency integrated circuits.

  • Maxillary anterior crown fractures are a common form of injury that mainly affects children and adolescents. The position of maxillary incisors and their eruptive pattern carries a significant risk for trauma. In the pre-adhesive era, fractured teeth needed to be restored either with pin-retained inlays or cast restorations that sacrificed healthy tooth structure and were a challenge for dentists to match with adjacent teeth. But. recently the development of adhesive dentistry has allowed dentists to use the patient's own fragment to restore the fractured tooth. The purpose of this paper is to present 2 cases of reattachment of fractured teeth which had different fracture mode, and to evaluate prognosis of cases.

  • Nitrogen pollution in urban and rural groundwater is a common problem and poses a major threat to drinking water supplies based on groundwater. In this work, the kinetics of nitrification-denitrification coupled reactions are modeled and new reaction modules for the RT3D code describing the fate and transport of nitrogen species, dissolved oxygen, dissolved organic carbon, and biomass are developed and tested. The proposed nitrogen transformations and transport model showed very good match with the results of other public codes.
