  • In this study, $Bi_2O_3-B_2O_3-ZnO$ glass system, which was expected to have similar properties with PbO containing glass system, was selected as a PbO replaceable potential composition because the atomic weight and ionic radius of Bi is similar to those of Pb. Glasses with different modifier/former ratio were prepared by melting the raw ingredient mixtures in $Bi_2O_3-B_2O_3-ZnO$ system, and the thermal and electrical properties of the sintered samples were examined. The glass transition temperatures and the dielectric constant of the glass pellets were between 350 $^{\circ}C{\sim}$500 $^{\circ}C$ and 15-35, respectively.

  • A component is a reusable and replaceable software module accessed through its interface. Component-based development is expected to shorten the development period, reduce maintenance costs, and improve program reusability and the interoperability of components. This paper proposes a new robot software component platform in order to support the entire process of robot software development. It consists of specifications of a component model, component authoring tool, component composer, and component execution engine. To show its feasibility, this paper presents the analysis results of the component's communication overhead, a comparison with other robotic software platforms, and applications in commercial robots.

  • Analysis of interferon alpha (IFN) modified with high molecular weight branched PEG was performed by capillary electrophoresis (CE) and MALDI-TOF mass spectrometry (MALDI-TOF MS). IFN was modified by the reaction of amine residues with an active ester of monomethoxy polyethylene glycol at various molar ratios. As a CE method. capilary electrophoresis sodium dodecyl sulfate nongel sieving (CE-SDS NGS) was performed using an uncoated capilary filled with a hydrophilic replaceable polymer network matrix.

  • In ultra-high strength SFRCC(Steel Fiber Reinforced Cementious Composites), much silica fume are used to improve strength, flowability and durability. Silica fume have merits of filling the voids, enhancement of reheological chracteristics, production of secondary hydrates by pozzolanic reaction in reactive powder concretes. However silica fume has been imported in high-cost in domestic industry, we need to investigate replaceable material in stead of silica fume in a view of economy Therefore, in this paper, in order to investigate replacement of silica fume in ultra-high strength SFRCC we used the granulate blast-furnce slag with finess 4000, 6000, 8000. As a results, we have evaluated that the bigger the finess the more increase compressive strength of ultra-high strength SFRCC using the blast-furnce slag and there was no problem from the viewpoint of flowability and compressive strength when we use blast-furnce $50\%$ with replacement ratio of silica fume

  • The pi-cell [1] is known as one of the candidates for a fast response time and a good viewing angle characteristics due to a self-compensated configuration and can be a replaceable mode instead of the current TN mode and the IPS mode for moving picture in future. This paper shows the optimized condition to maintain bend state instead of splay state, which is mortal demerit for good optical properties in a pi-cell, by using the polymer stabilized method [2]. The good electro-optical characteristics are also obtained by optimizing the various factors, which are monomer concentration in a LC, UV intensity, curing time, curing voltage, and curing temperature, and by using retardation film. We use a scanning electron microscope to study the structures of the polymer stabilized polymer network in a pi-cell as a key to figure out why bend state is occurred.

  • 누에인공사료의 조성중 필수적인 cellulose성분을 천연의 자원에서 개발하기 위해 뽕나무가지, 미류나무가지, 리기다소나무와 이태리포프라의 펄프분말, 왕겨, 톱밥, 볏짚등을 대상으로 실험하였다. 실험결과 뽕나무가지와 리기다소나무펄프가 인공사료의 cellulose대치 가능 자원임이 밝혀졌다. 특히 뽕나무가지의 화학적인 처리방법에 의하여 누에성장발육에 보다 유용한 제품을 얻을 수 있었고, 나아가서 장차 인공사료개발에 cellulose원으로서의 역활을 기대할 수 있게 되었다.
