  • For a fire cause judgement this paper describes the short circuit characteristics of a electric wire through the cross section analysis under ac condition. The cower wires prepared for the experiment were 1.2mm, 1.6mm, and 2.0mm in diameter. Through the cross section analysis(CSA), it was confirmed that the dendrite structure grew at the angle of about $40^{\circ}\;or\;60^{\circ}$ when the fusing current was applied to the wires. The larger the fusing current is, the more decreased the growth angle of the dendrite structure is. It was confirmed that the dendrite structure was arranged like the columnar structure. In this paper, the characteristics analysis of short circuit was carried out in the range of transient duration and the correlation constant k was investigated by measuring the short circuit duration and the fusing current.

  • This paper describes a green stripping process to effectively strip the remaining DFR layer on a non-alkali-based ITO glass surface after an etching process. A stripper, water-soluble amine compound, is used to investigate the characteristics of stripping ability and to suggest a valid method for the green process. Increasing the composition (5-30% concentration) of the ethanol amine-based stripper was found to greatly reduce the stripping time applied in the dipping method. The composition (30%) achieved an excellent stripping effect and free-residue impurities. Additionally, it was possible to obtain the effect of stripping in a way to sustain the release before generating DFR sludge from the ITO glass surface by using dipping condition (stripping time) in the composition. An Additional stripping process (buffering) out of dipping can realize productivity improvement and cost reduction because of the higher proportion of re-use of the stripping solution used in the DFR removal step.

  • 이 논문은 화재원인판정에 있어서, 교류전류에 의해 용융된 나전선의 발열특성을 기술한 것이다. 실험을 위해 동전선은 1.2[mm], 1.6[mm], 2.0[mm]의 직경인 것을 준비하였다. 단면분석을 통해 용단전류가 전선에 공급되었을 때, 수지상 조직은 약40[$^{\circ}$] 또는 60[$^{\circ}$]의 각도로 성장하는 것을 확인하였다. 용단전류가 커지면 커질수록 수지상 조직의 성장각도는 줄어들었다. 그것은 주상조직과 유사하다는 것을 확인하였다.

  • The goal of this research is to investigate the effect of fusible interlinings on the mechanical characteristics and appearance related values for the Lyocell fabrics. In this study, to establish optimum fusing conditions, peel strength of the fused fabrics depending on the fusing temperature, pressure and time was measured. Appearance related properties and mechanical characteristics of the fused fabrics ere determined. The reulst are as follows: In the fusing condition of $120^{\circ}C,\;3kgf/textrm{cm}^2$, 15sec, peel strength was excellent. Peel strength was excellent in the case of tencel/cotton fabric, with increasing cover factor of woven interlining, with twill and nonwoven interlining. Flex stiffness was increased in the case of tencel/cotton fabric, with increasing weight of woven interlining, with twill and nonwoven interlining. Drapability was excellent in the case of 100% tencel fabric, with decreasing weight of woven interlining, with plain and woven interlining. Crease recovery was excellent in the case of 100% tencel fabric, with increasing weight of woven interlining, with twill and woven interlining. Shear and bend properties were increased in the case of tencel/cotton fabric, with increasing weight of woven interlining, with plain and nonwoven interlining.

  • In this work, the effect of fusible interlining on the appearance related properties and mechanical characteristics of Lyocell fabric after fusing was investigated. Two different types(20's and 10's) of Lyocell face fabric with six different interlining(by thickness and structure) for earth Lyocell fabric were examined. In order to establish the optimum fusing condition for the different face fabric and interlining, peel strength of each fused fabric was measured, which was dependent on the fusing temperature, pressure, and time. The characteristics related appearance and mechanical characteristics of each fused fabric were determined. The results are as follows: The peel strength was excellent, when the fabric was fused with the force of 3kgf/$textrm{cm}^2$ at $120^{\circ}C$ for 15seconds. Flex stiffness, G, 2HG, 2HG5(shear), B, 2HB(bending) of 100% Lyocell fabric 10's were higher than those of 100% Lyocell 20's. Flex stiffness, crease recovery, G, 2HG, B, 2HB of thicker woven interlining were higher than those of thinner woven interlining. Crease recovery of twill interlining were higher than those of plain interlining. In case of shear and bending properties, however, plain interlining was higher than twill interlining. Flex stiffness, crease recovery, G, 2HG, 2HG5, B, 2HB of nonwoven interlining were higher than those of woven interlining. In case of drapability, however, woven interlining was higher than nonwoven interlining.

  • Human being recognizes emotion fusing information of the other speech signal, expression, gesture and bio-signal. Computer needs technologies that being recognized as human do using combined information. In this paper, we recognized five emotions (normal, happiness, anger, surprise, sadness) through speech signal and facial image, and we propose to method that fusing into emotion for emotion recognition result is applying to multimodal method. Speech signal and facial image does emotion recognition using Principal Component Analysis (PCA) method. And multimodal is fusing into emotion result applying fuzzy membership function. With our experiments, our average emotion recognition rate was 63% by using speech signals, and was 53.4% by using facial images. That is, we know that speech signal offers a better emotion recognition rate than the facial image. We proposed decision fusion method using S-type membership function to heighten the emotion recognition rate. Result of emotion recognition through proposed method, average recognized rate is 70.4%. We could know that decision fusion method offers a better emotion recognition rate than the facial image or speech signal.

  • 목적: 본 연구는 글라스 용융침투 처리가 지르코니아와 초저온 소성 전장도재와의 전단결합강도에 미치는 영향을 평가하였다. 재료 및 방법: 표면처리 방법에 따라 대조군 (처리 안함), ZirLiner처리군 (ZL군), 글라스 용융침투처리군 (ZG군), 글라스 용융침투 후 Sandblasting 처리군 (ZGS군)으로 분류하였다 (n = 12). 모든 실험군은 초저온 소성 전장도재를 사용하여 지름 6 mm ${\times}$ 두께 3 mm가 되도록 축성하고 소성하였다. 지르코니아와 전장도재 사이의 결합강도는 만능시험기를 이용하여 측정하였고 지르코니아 시편의 결합계면, 도재파절 양상은 SEM과 EDX로 관찰하였다. 결과: 지르코니아 표면처리 방법에 따라 전장도재와의 결합강도가 ZirLiner군, 대조군, 글라스 용융침투군 순으로 나타났으나 통계학적으로 유의한 차이는 없었다 (P > .05). 글라스 용융침투 후 Sandblasting 처리군은 다른 모든 군에 비해 유의하게 낮은 전단결합강도를 보였다 (P < .05). 결론: 글라스 용융침투 지르코니아의 Sandblasting처리는 초저온 소성 전장도재와의 현저한 결합력 감소를 야기시키므로 사용이 제한되어야 할 것으로 사료된다.

  • In this research, an expert system has been developed to select optimum well-matched fusible interlinings with a face fabric. First, a database of face fabrics and fusible interlinings has been constructed. And knowledge acquisition has been performed from the previous studies about the properties of fusible interlinings and fused composites as well as fusing prsocess quality control. Then, a rule-based knowledge-base has been constructed through knowledge classification. Finally, we have constructed an inference engine with the knowledge-base. The expert system enables us to easily select optimum fusible interlinings for a face fabric considering high quality fused composites and fashion trend.

  • Recently, Gonzalez-Audicana et al. proposed the substitute wavelet intensity (SWI) method which provided a solution based on the intensity-hue-saturation (IHS) method for the fusing of panchromatic (PAN) and multispectral (MS) images. Although the spectral quality of the fused MS images is enhanced, this method is not efficient enough to quickly merge massive volumes of data from satellite. To overcome this problem, we introduce a new SWI method based on a fast IHS transform to implement efficiently as an alternative procedure. In addition, we show that the method is well applicable for fusing IKONOS PAN with MS images.

  • In this paper, we studied the cross section analysis based on the short circuit conditions of the low voltage bare wires. The copper wires prepared for the experiment were 1.2mm 1.6mm and 2.0mm in diameter. Through the cross section analysis(CSA), it was confirmed that the dendrite structure grew at the angle of about $40^{\circ}$ or $60^{\circ}$ when the fusing current was applied to the wires. The larger the fusing current is, the more decreased the growth angle of the dendrite structure is. It was confirmed that the dendrite structure was arranged like the columnar structure. In this paper, the characteristics analysis of short circuit was carried out in the range of transient duration.
