biomaterial which has been an interesting area as improvement of manufacturing technology was focused to tailoring the morphological structures of fabricated one for various applications including tissue repair, wound healing, implant, and drug delivery system. Electrospinning technology has been utilized to fabricate nano-size fibers formed by subjecting a fluid jet to a high electric field. The ability to generate nanofibers, which mimic the size scales of fibers composing the extracellular matrix of native tissues and organs, has been developed for a long time. In this paper the high porous 3-D scaffold of biodegradable electrospun nanofibers could be manufactured with blowing agents and the fabricated structures were characterized via an optical microscopy, scanning electron microscopy, and thermo-mechanical test. Also, the tailored scaffolds were analyzed in the aspect of degradation behavior.

The purpose of this study is to recognize the importance of the color of repainting apartment, and to refer to it in future self-governing body in case of color plan during urban landscape planning by analyzing the exterior colors of apartment by metropolitan city as major lodgement areas. This study was to provide basic data on the exterior colors of apartment an important color environment in the city by quantitatively analyzing the hue, lightness, and saturation widely used in apartments during repainting. As a result of analyzing the exterior colors of 36 repainting apartments in metropolitan cities across the country, this study showed a tendency that the colors of Blue(B) series and Purple Blue(PB) series were the main ones, and some Orange(YR) series appeared. This study has found out that the Gray series of colors in low brightness were excluded and that the Deep Blue series of colors in mid-low brightness were most commonly used as accent color. Rather than using various colors, it showed similar density by region, and similar color series of Tone on tone coordination were the main ones. Rather than various dominant colors, Yellow series or Blue(B) series of limited dominant colors were used, and secondary colors were used within a small range of middle brightness and middle saturation. In case of saturation, this study has found out that calm colors were used in middle and low saturation areas.

To fabricate uniform nano/micro size beads by using an electrospraying process, PMMA polymer solution was ejected from a reservoir tip and formed into a suspended droplet by force of controllable syringe pumping. As a complex electric field and newly designed electrodes connected with a nozzle were applied, uniform microsize beads of the solution were obtained from an apex of the Taylor-cone at a nozzle and were traveled towards a target electrode which could provide non-uniform electric field. Moreover by using a 2 axis x-y stage, we could obtain uniform size PMMA beads which were deposited on the thin poly(ethylene terephthalate) film. To understand the effect of process variables, applied field conditions and rheological properties, the morphological pictures of the deposited particles were investigated through the optical and scanning electron microscope.

WMT(Windosw Media Technologies)는 Microsoft에서 만든 인터넷 또는 인트라넷상에서 고품질의 오디오/비디오를 실시간으로 전송하여 주는 멀티미디어 스트리밍 기술이다. WMT는 대부분의 로컬 및 스트리밍 멀티미디어 파일 형식을 지원하기 때문에 개발자들은 어떤 웹 어플리케이션이나 사이트에라도 오디오와 비디오 방송을 구축할 수 있다. WMT에 포함된 Windows Media Encoder, Windows Media On Demand Producer등을 이용하고 전용서버를 설치하여 on-Demand방송이나 실시간 인터넷 방송을 구축할 수 있다. WMT is the multimedia streaming technology which transfer the audio and video on Internet or Intranet. Because WMT supports almost styles of local and streaming multimedia file, some developers build the radio and video broadcasting system at any web applications and sites. This paper shows the method of develop the realtime internet broadcastion system with WMT.
