온종아리신경 마비를 가진 환자에 대한 키네지오 테이핑의 효과는 연구되지 않고 있다. 따라서 본 연구의 목적은 온종아리신경 마비로 인한 발목 관절 부위의 기능적인 움직임이 제한된 환자를 대상으로 키네지오 테이핑의 효과를 알아보고자 한다. 본 연구는 온종아리신경 마비를 가진 10명을 대상으로 연구를 실시하였다. 키네시오 테이핑 적용은 발목관절에 적용하였다(발등굽힘, 바깥들림 방향). 키네지오 테이핑의 효과를 알아보기 위해 발목 관절의 도수근력검사(앞정강근, 긴종아리근), 능동 관절가동범위(발등굽힘, 바깥들림), 통증(시각사상척도, 통증 압력의 역치) 및 균형(한 발 서기동작)을 실시하였다. 측정은 중재 전, 중재 8주에 측정을 실시하였다. 연구결과 온종아리신경 마비 환자의 발목 관절에 키네지오테이핑을 중재 후 도수근력검사, 능동 관절가동범위, 통증, 균형을 모두 향상시켰다. 이러한 연구결과를 바탕으로, 발목관절에 키네지오 테이핑 적용은 온종아리신경 마비 환자의 발목기능 및 통증과 균형에 효과적인 것을 알 수 있었다.

A common failure mechanism in bulk CMOS integrated circuits is the latch-up of parasitic SCR structure inherent in the bulk CMOS structure. Latch-up triggering and holding charac-teristics have been measured in the test devicrs which include conventional and Schottky-damped CMOS structures with various well depths and n+/p+ spacings. It is demonstrated that Schottky-clamped CMOS is more latch-up immune than conventional bulk CMOS. Finally, the simulation results by circuit simulation program (SPICE) are compared with measured results in order to verify the validity of the latch-up modal composed of nan, pnp transistors and two external resistors.

Meteorologists define a drought as a period of common dry weather. This may sound straightforward, but it is not so in reality. In this study, we attempted to identify meteorological drought conditions over South Korea. To evaluate the temporal and spatial variability of drought, we calculated two commonly used drought indices, the percent of normal precipitation (PNP) and the Palmer drought severity index (PDSI) calculated from fifty-eight meteorological stations below the Korean Meteorological Administration (KMA). The yearly precipitation has been growing gradually, and the amplitude between maximum and minimum also grow more explicitly from 1960's. According to the analysis of percentile anomaly of monthly precipitation, major drought duration was $1927{\sim}1929,\;1937{\sim}1939,\;1942{\sim}1944,\;1967{\sim}1968,\;1976{\sim}1977,\;1982{\sim}1983,\;1988,\;and\;1994{\sim}1995$. The severe drought occurred most frequently in Mokpo, Daegu, Jeonju, Busan, and Gangneung; it tended to occur more frequently in south sector than in mid sector of Korea and in south west sector than in south east sector. According to the analysis of seasonal distribution, extreme droughts occurred frequently in winter at Seoul, Gangneung, Jeonju, Daegu, and Busan. Severe droughts in summer were formed frequently at Seoul, Gangneung, and Mokpo, while that for spring at Jeonju, Daegu, and Busan. The results of PDSI distribution for the $1994{\sim}1995$ drought period were one of the most severe and widely spreaded droughts; it occurred most frequently in the south sector of South Korea. The comparison of time series between PDSI and Normal Percent showed that they exhibit a strong compatibility for the entire study period; it implies that both drought indices are useful method to indicate drought severity.
