This study is intended to understand an implication system and significance in the current community which a body image symbolizes by correlating it with fashion that is on the rise as a principal issue in various fields. For this study, the symbolism of the body image was contemplated in terms of philosophy and art, and then on the basis of it, the symbolism of the body image shown in modern fashion design was analyzed through fashion works. The research results are as follows, 1. The manifestation of sex can be taken as the symbolism of the body image which is expressed in modern fashion design. Recently sexual chaos and vagueness such as homosexuality and bisexuality are expressed through a dress and its ornaments. Though displaying sexual characteristics of male and female as they are exposing a sign or a diagram, decorating a part of body or representing sex in garments, uncertain sex identity in modern society is manifested in dress and its ornaments. It is to deny absoluteness regarding sex and emphasize diversity indwelt in human beings, and after all it shows to pursue the human essence. 2. Another symbolism of the body image is body expression as the human race and an ethnic group. The discriminating situations and the restoration of their status appeared in modern fashion too. Moreover, their cultures and issues came to alter the aesthetic standard of body made from a view of the Western white supremacist. Hereupon, fashion trends like ethnic fashion, Orientalism and African look etc. appear according to this tendency, which represents race and national identity and in addition, which signifies to present transcendental human conception embracing alienated human conception. 3. The symbolism of the body image expressed in a body, and a dress and its ornaments as nature can be considered in terms of the concern on environmental contamination and the respect of echo system. Getting away from reigning over, developing and stamping down nature at their will, the human beings pursue unity with nature, which is described in fashion. They are stressing that natural materials and objects such as animal, plant and soil etc. should activily be introduced into fashion and humans are a communal fate group and should reframe their status in nature at last. 4. The body image shown in a body, a dress and its ornaments as technology is transformed and recreated by modern scientific techniques and medical science to show post human conception namely, forthcoming future human conception as a cyborg which loses individual identity. This presents a perfect future human conception with high level of preternatural power but after all, leaves us a task to seek the meaning of human existence in alienation caused by the loss of human identity and existence. In this manner, the moderns crave for perceiving the identity of a natural human being in the current thoughts tendency of the modern times such as postmodernism, post structuralism, deconstructionism, feminism and so on, which build discussions affecting the art and fashion worlds. The categories, like sexual characteristics indwelt in a human body, racial classifications, the natural environment surrounding human beings and development of science, bring out the importance of the internal and external meaning in today's fashion which a human body contains, and present sew human conception in the coming future society.

The accelerated thermal aging of a CSPE were carried out for 0, 80.82, 161.63 days at $100^{\circ}C$, which are equal to 0, 40 and 80 years of aging at $50^{\circ}C$, respectively. The volume electrical resistivities of the seawater and freshwater flooding were measured through 3-terminal circuit diagram. The volume electrical resistivities of the 0y, 40y and 80y were $2.454{\times}10^{13}{\sim}1.377{\times}10^{14}{\Omega}{\cdot}cm$, $1.121{\times}10^{13}{\sim}7.529{\times}10^{13}{\Omega}{\cdot}cm$ and $1.284{\times}10^{13}{\sim}8.974{\times}10^{13}{\Omega}{\cdot}cm$ at room temperature, respectively. The dielectric constant of the 0y, 40y and 80y were 2.922~3.431, 2.613~3.285 and 2.921~3.332 at room temperature, respectively. It is certain that the ionic ($Na^+$, $Cl^-$, $Mg^{2+}$, ${SO_4}^{2-}$, $Ca^{2+}$, $K^+$) conduction current was formed by the salinity of the seawater. The volume electrical resistivity of the cleaned CSPE via freshwater trends slightly upward with the number of dried days at room temperature. As a result, the $CH_2$ component of thermally accelerated aged CSPE decreased after seawater and freshwater flooding for 5 days respectively, whereas the atoms such as Cl, O, Pb, Al, Si, Sb, S related with the conducting ion ($Na^+$, $Cl^-$, $Mg^{2+}$, ${SO_4}^{2-}$, $Ca^{2+}$, $K^+$) component increased relatively.

Because the cage assembly serves as the launch platform, an accurate aim is essential to ensure shooting accuracy for the target. On the other hand, the abnormal rotation of the cage due to the directional errors of the K-MLRS has continuously caused quality problems. The quality problem of weapon systems may have a negative impact on the military's power loss. In this study, improvement plans were derived by examining the defects and analyzing the directional errors of the K-MLRS launcher. In addition, all possible causes of directional errors were derived from the flow diagram for cage directionality. Based on the results, the defense design through the software program was intended to prevent the loss of direction. Through this study, the signal error of the resolver was improved by preventing unspecific signals in the data. Furthermore, the directional judgment method was improved to minimize the impact of data distortion. Lastly, directional storage and verification methods were improved so that data for the cage rotation direction would not be affected by errors. For the design improvement method, the reliability was verified through the system applicability. This study is expected to be a reference for failure analysis and design for similar weapon systems in the future.

In this paper, a couple of 4-channel differential transimpedance amplifier arrays are realized in a standard 0.18um CMOS technology for the applications of linear LADAR(laser detection and ranging) systems. Each array targets 1.25-Gb/s operations, where the current-mode chip consists of current-mirror input stage, a single-to-differential amplifier, and an output buffer. The input stage exploits the local feedback current-mirror configuration for low input resistance and low noise characteristics. Measurements demonstrate that each channel achieves $69-dB{\Omega}$ transimpedance gain, 2.2-GHz bandwidth, 21.5-pA/sqrt(Hz) average noise current spectral density (corresponding to the optical sensitivity of -20.5-dBm), and the 4-channel total power dissipation of 147.6-mW from a single 1.8-V supply. The measured eye-diagrams confirms wide and clear eye-openings for 1.25-Gb/s operations. Meanwhile, the voltage-mode chip consists of inverter input stage for low noise characteristics, a single-to-differential amplifier, and an output buffer. Test chips reveal that each channel achieves $73-dB{\Omega}$ transimpedance gain, 1.1-GHz bandwidth, 13.2-pA/sqrt(Hz) average noise current spectral density (corresponding to the optical sensitivity of -22.8-dBm), and the 4-channel total power dissipation of 138.4-mW from a single 1.8-V supply. The measured eye-diagrams confirms wide and clear eye-openings for 1.25-Gb/s operations.
