  • Strength development of concrete subjected to cold weather is generally delayed due to its low temperature. In case of soil nailing method, it is necessary to apply the shotcrete. However, the shotcrete placement under low temperature experiences retardation of strength development due to delayed hydration reaction. Therefore, in this paper, the use of fine particle cement which is produced through particle classification in cement manufacturing process, is discussed to enhance the strength development of the shotcrete under low temperature. According to the results, the concrete containing 100% of fine particle cement had excellent strength development even at $-9^{\circ}C$ of temperature and at 5days, it reached design strength with PE film curing. It is thought that more than 70% of fine particle cement can secure required strength of the shotcrete even at low temperature condition.

  • To grow the large diameter GaN with high structure and optical quality has been obtained by hydride vapor phase epitaxy(HVPE) method. In addition to the nitridation of $Al_2O_3$ substrate, we also developed a "step-growth process" to reduce or to eliminate the bowing of the GaN substrate caused by thermal mismatch during cool down after growth. The as-grown 380um thickness and 75mm diameter GaN layer was separated from the sapphire substrate by laser-induced lift-off process at $600^{\circ}C$. A problem with the free-standing wafer is the typically large bowing of such a wafer, due to the built in the defect concentration near GaN-sapphire interface. A polished G-surface of the GaN substrate were characterized by room temperature Double crystal X-ray diffraction (DCXRD), photoluminescence(PL) measurement, giving rise to the full-width at half maximum(FWHM) of the rocking curve of about 107 arcsec and dislocation density of $6.2\times10^6/cm^2$.

  • As the importance of information audit is getting bigger, the public corporations invest many expenses at information system audit to build a high quality system. For this purpose, there are much research to proceed an audit effectively. In database audit works, it could audit utilizing a variety of monitoring tools. However, when auditing SQLs which might be affected to database performance, there are several limits related to SQL audit functionality. For this reason, most existing monitoring tools process based on meta information, it is difficult to proceed SQL audit works if there is no meta data or inaccuracy. Also, it can't detect problems by analysis of SQL's syntax structure. In this paper, we design and implement the SQL Inspector using ANTLR which is applied by syntax analysis technique. The overall conclusion is that the implemented SQL Inspector can work effectively much more than eye-checked way. Finally, The SQL inspector which we proposed can apply much more audit rules by compared with other monitoring tools. We expect the higher stability of information system to apply SQL Inspector from development phase to the operation phase.
