We must diagnose and treat as early as possible to the children that have been danger factor and have delayed development, therefore, we shall decrease to disability, shall able to ADL and shall have could live to normal living. Since the children are most fast grow to development during 1 year after birth, the soft sign of cerebral palsy is transverse to the hard sign.
Vestas 660 kW 풍력발전 시스템의 전기품질 평가
박성기,김일환 제주대학교 공과대학 첨단기술연구소 2003 尖端技術硏究所論文集 Vol.14 No.2
This paper presents the power quality assessment of Vestas 600kW wind turbine generation system which is located in Haeng-Won wind farm in Jeju. By the standard of IEC 61400-21 issued on the power quality of wind power generation measurement and assessment are completed. Finally it is shown that there are power factor and voltage harmonic problem in the bin of low wind speed.
도전성지주에 평행한 반파장 Dipole Antenna의 전류분포
박성기 대한전자공학회 1967 전자공학회지 Vol.4 No.2
도전성지주가 '안테나'의 방사에 주는 영향을 고찰하기 위하여 Dipole '안테나'를 도전성지주에 매우 가까히 놓고 여진하였을 경우의 전류의 분포를 해석 및 실측하였으며 양자가 잘 일치함을 확인하였다. On clarifing radiations from antenna, it is necessary to consider the contribution of the current distribution on te conductive supporter. The expression has not only analized the total radiative current distribution on the dipole antenna and its conductive supporter, in case when the former was placed closely and in parallel to the latter, but also shown the results of practical experiment.

This study are decided the mix proportion method of latex modified concrete for agricultural concrete structures from the results of workability and strength test with mix proportion factor. For mix proportion factor, this study are selected the water-cement ratio, unit cement amount and latex content. Also, this study were performed the slump, compressive strength test and microstructure analysis using the scanning electron microscope(SEM). The strength and slump of LMC are dependent with unit cement amount, latex content, and water-cement ratio. Especially, the strength of LMC are not controlled by single mix proportion factor but effected by combined mix proportion factor. Microstructure investigation are showed the LMC are reduced the internal pore volume and enhanced the transition zone between cement paste and aggregate interface. This effect get by consist of latex films in the concrete. Also, this study were recommended the mix proportion method for LMC. These mix proportions method are estimated the mix design for satisfied the target performance which are applied the agricultural concrete structure.
