The properties of $Al_2O_3$ thermoluminescent phosphor have been observed to apply for gamma dosimetry in vivo. Glow peaks at 380, 420, 490 kelvin temperature with emission in the blue region have been detected and calculated as 1.4 eV the activation energy by means of heat response rising time method. Sensitization and supralinearity in $Al_2O_3$ phosphor could be consistently explained by the deep trap model. Studies of the thermoluminescence growth rate with gamma ray exposure showed linearly to $10^4$ Roentgen and then supralinear rate detected 1.2 power of exposure dose sensitization of $Al_2O_3$ is described five times more than TLD-100 and the fading time is shorter and then tried to apply for gamma dosimetry in vivo.

본 연구는 릴리즈 댄스(Release Dance)에 내재되어 있는 선사상을 밝혀내고자하는데 그 목적이 있다. 이를 위해 릴리즈 댄스의 대표적인 안무가인 트리샤 브라운의 사례를 문헌연구하였다. 먼저 브라운이 훈련했던 것으로 알려진 알렉산더 테크닉(Alexander Technique)은 편안함, 감각각성, 무형식의 특징을 통해 선사상을 내재하고 있음을 알 수 있었다. 브라운의 무용에서는 부드러운 움직임, 공간인지, 무질서함의 특징으로 전이되어 나타났다. 브라운 외에도 많은 안무가들이 하나의 신체훈련으로 소매틱스(Somatics)를 접하고 이를 움직임에 반영해왔다. 관련된 사례연구들을 수행하여 릴리즈 댄스자체에 대한 학술적 정의가 필요한 시점이다.

현재까지 우리나라 하천관리는 기존의 도면관리 및 현장조사를 통한 정보관리에서 벗어나 WAMIS, RIMGIS와 같은 물 관련 하천기본지리정보 시스템을 구축하여 사용되어 왔다. 하지만 기 구축된 시스템들은 선(線) 중심의 2차원 하천 공간자료로 관리되어 실무자 중심의 친환경적 하천관리업무 지원을 위한 자료로서 활용성이 부족한 실정이다. 본 연구에서는 면(面) 중심의 입체적인 3차원 하천공간정보 구현과 체계적인 하천관리 업무가 가능하도록 항공사진(아날로그, 디지털) 및 다양한 위성영상에 대한 해상도 비교를 통한 하천 적용여부 분석을 수행하였다. 하천 적용성 분석을 통해 가장 효과적으로 판단되는 디지털 항공사진을 이용하여 하천관리 및 활용방안을 모색함으로써 효율적인 하천관리방안을 제시하고자 한다.

Crystal structure of tension, opposite and lateral wood of Platanus orientalis L. were analysed in some aspects of crystallinity index, crystallite size, d-spacing of (200) and (004), and integrated intensity ratios with X-ray diffraction method. Crystallinity index and crystallite width in tension wood appeared somewhat larger than opposite or lateral wood. However, d-spacing and integrated intensity ratios were nearly identical irrespective of tension, opposite, and lateral wood.

This study was done to provide basic data for clothing design and thus to contribute to the academic development at the clothing and textile area and collar roll line lay down angle variation at collar width on the open collar. The study was composed as tallows: 1. The variation at collar outer wall size increase collar roll line lay down angle size the more Increase. 2. The outer wall and stand height size increase aware at variation collar width at the more Increase. It is desirable that this study will be at help to enchancement of life style in garments and promotion of garments industury by developing the archetype basic collar pattern suitable to Korean women's garments.

Most buildings and factories are supplied with electric power by three-phase four-wire low voltage electric distribution system. This method pollutes the neutral line and utility sources with harmonic currents. Today, development of power conversion technology and the popularization of computer cause the neutral current to become serious. In this paper, a novel three-phase four-wire active filter is proposed to solve these harmonic problems has two purposes. The first purpose of the proposed active filiter is that the phase current has a sinusoidal waveform shape under the nonlinear load. The second purpose of the proposed active filiter is that the current on the neutral line become zero under the unbalanced power source and under the varring load conditions. The ability of the shunt active filiter has been proved to be excellent through simulations under the varring load conditions.
