Gait is a new biometric aimed to recognize a subject by the manner in which they walk. Gait has several advantages over other biometrics, most notably that it is a non-invasive and perceivable at a distance when other biometrics are obscured. We present a new area based metric, called gait masks, which provides statistical data intimately related to the gait of the subject. Early results are promising with a recognition rate of 90% on a small database of human subjects. In addition to this, we...

본 논문에서는 1800년 1월 1일자 Phil. Trans. R. Soc. Lond.에 게재된 Frederick William Herschel의 적외선에 관한 4편의 시리즈 논문을 기반으로 초등과학영재 프로그램을 개발하였다. 프로그램 구성을 위한 학습모형은 Joseph Renzulli의 삼부심화학습모형을 사용하였다. 삼부심화학습모형의 제1부에서는 적외선의 다양한 응용을 제시하여 학생들이 적외선에 대해 관심을 갖도록 유도하였으며, 제2부에서는 적외선의 발견에 관한 실험과 광학적 특성을 파악하는 실험을 수행하도록 하였다. 제3부에서는 2부에서 획득한 지식과 기법을...

condition was optimized in order to maximize the NO decomposition efficiency. The highest NO decomposition efficiency obtained was 94.3% at the power consumption of 19.8 W for the frequency of 10 kHz. NO decomposition efficiency increased with increasing residence time or with decreasing initial concentration of NO. As the thickness and melting point of the electrode increased, the NO decomposition efficiency was improved. It was also found that CH4 was an effective additive in this experiment.

현대사회의 경제성장 및 의학의 발달은 국민건강을 증진시키고 평균수명을 연장시키는 데 기여해왔다. 2000년 중반에는 65세 이상의 노인의 비율이 이미 7.1%가 넘었으며 2020년경에는 14.3%가 되어 본격적인 고령화 사회가 될 것으로 전망하고 있다. 이러한 고령화 사회로의 변화로 인해 다양한 노인문제에 대한 학계의 관심이 고조되고 있다. 그러나 노인 인구의 증가에 비해 도시의 핵가족화 및 개인주의 문화 형태는 노인을 부양해야할 인구 층을 크게 감소시켰을 뿐 아니라 단독가구노인 증가 및 독거거주노인의 증가를 가져오게...

of CF. The obtained Raman spectra indicate that the outer surface of CF evolves from turbostratic structures into a three-dimensional ordered state after being irradiated by a laser. The X-ray diffraction data revealed that the growth of crystallite was parallel to the fiber axis, and the interlayer spacing d002 decreased from 0.353 to 0.345 nm. The results of scanning electron microscopy revealed that the surface of irradiated CFs was rougher than that of the unirradiated ones and there were...

We demonstrated the sensitivity of optically active single-walled carbon nanotubes (SWCNTs) with a diameter below 1 nm that were homogeneously dispersed in cement composites under a mechanical load. Deoxyribonucleic acid (DNA) was selected as the dispersing agent to achieve a homogeneous dispersion of SWCNTs in an aqueous solution, and the dispersion state of the SWCNTs were characterized using various optical tools. It was found that the addition of a large amount of DNA prohibited the...

electrode materials. The resultant porous carbons (PS-600, PS-700, PS-800, and PS-900) were utilized as electrode material for supercapacitors. To our delight, the PS-900 demonstrated a maximum specific capacitance (Cs) of 303 F g?1 in 1.0 M H2SO4 at a scan rate of 5 mV. The electrochemical impedance spectra confirmed the poor electrical resistance of the electrode materials. Moreover, the stability of the PS-900 was found to be excellent (no significant change in the Cs even after 6000 cycles).

The aim of this work was to evaluate the dielectric properties of impregnated and activated palm kernel shells (PKSs) samples using two activating agents, potassium carbonate (K2CO3) and sodium hydroxide (NaOH), at three impregnation ratios. The materials were characterized by moisture content, carbon content, ash content, thermal profile and functional groups. The dielectric properties were examined using an open-ended coaxial probe method at various microwave frequencies (1?6 GHz) and...
