반도체 산업에서는 반도체 소자의 고집적도와 고기능화로 인하여 전반적으로 생산설비의 자동화가 급격히 발달함에 따라 생산라인의 관리자동화가 필연적으로 요구되고 있다. 이것은 컴퓨터 network에 의한 콘트롤과 자동운반 시스팀에 의한 공정제어를 실시하기 때문이다. 이러한 시스팀들의 특징은 feed forward, feed back 에 의한 정확한 공정제어와 on line, real time의 데이터 수집, 해석을 한다. 그러나 전반적인 자동화를 실현하려면 웨이퍼의 자동 handling 기술, 고성능 센서의 개발 등이 문제점으로 남아있다.

The objective of this research is to analyze whether the ground granulated blast furnace (GGBF) slag, by-product of industry in domestic iron-foundary, can be useful as a mineral admixture for concrete by investigating physical and chemical property. In addition, according to making an fundamental experiment on mortar and concrete mixed with GGBF slag to some grade, examining the consistency, the compressive strength and the resistance to sulfate attack of concrete and mortar, the acquired results are that the compressive strength was increased and the resistance to sulfate attack was predominant.

The combustion properties required for fire simulations of multi-layer, multi-component flame retardant cables were measured using a cone calorimeter. The CO and soot yields combustion efficiencies of the flame retardant cables were investigated. TFR-8 (flame retardant PCV and XLPE added), TFR-CVV-SB (flame retardant PCV and general PVC), and VCTF, which are excellent in the flame retardancy of cables, were considered. As the main result, the CO yield (y_CO) of the TFR-8 and TFR-CVV-SB flame retardant cables increased by 23% and 16%, respectively, with increasing incident radiation heat flux from 25 kW/㎡ to 50 kW/㎡. On the other hand, the CO yield of VCTF was not influenced significantly by the changes in radiant heat flux. Finally, the soot yield and combustion efficiency increased as the sheath material (flame retardant performance) was strengthened. Therefore, in a fire environment where various heat fluxes coexist, attention should be paid to the top of the application of the combustion property of the flame retardant cable.
