This paper, at the result for test to find singularity on identifying melting cause of short from folding by physical external force to happen in the midst of using cord, can recognize that in case of short circuit by folding of cord, there is a formal difference among characteristics which cutting part within component wire accords with part of short circuit, fusion mark of external fire heat in the condition of power authorization and fusion mark in the condition of power unauthorization, in the condition of power authorization, component wire does not have component wire and only fusion mark is recognized and in the condition of power unauthorization, only lump of fusion is recognized.

In this study, recently it is urgently required that demolition building waste has to be recycled because urban development and reconstruction of old town are implemented. The quantity of construction and demolition waste is sharply increased. On the other hand, it has to be solved urgently for the unbalance of demand and supply about the aggregate because the using of natural aggregate is practically limited due to the large amount of aggregate is required. To meet the requirement of construction demand of aggregate, the manufacturing techniques of recycled concrete aggregate are urgently required. In this study, the general procedure of recycled aggregate producing system is introduced with the various experimental test results. This manufacturing system seems to produce the high quality recycled concrete aggregate with the eco-friendly, economical and mechanical properties.

In this study, experiments are conducted to find out the influence of leachate by low landfilling using recycled soil debris. Sieve analysis, X-ray fluorescence test, TCLP test and fish toxicity test were conducted using recycled soil debris from demolition building. The recycled soil debris was mixed with 20%, 30%, 50%, 75%, 100% of weathered granite soil by weight. In the result of TCLP, a quantity of heavy metal ion and aromatic compound satisfied a required upper value for concentration. The hydrogen ion concentration of soil specimen before mixing showed between pH 10 and pH 11. As a specimen was mixed by regular soil, the hydrogen ion concentration decreased till pH 8. Fish toxicity was tested in solution of leachate by soil mixture. In this case, a livability of minnow appeared about 60% of number on recycled soil and an activity of fish was retarded gradually as time goes on. A numerical analysis by Visual Modflow Ver. 2009 was proceeded for expecting to moving of pH concentration.
