The fate of a emergency patient is decided upon the extent of first aid in one hour after accident. Suitable diagnosis and treatment can raise the possibility of patient's life and reduce the recuperation time. We surveys papers which were The Korean Society Of Sports Medicine(1993-2004 yeas 405papers)and The Korean Society Of Emergency Medicine (1990-2004 yeas 797 papers). This paper got the following results through analyses of problems in emergency medical service system and of injures from sports. First, portable X-RAY equipment is needed to apply it to emergency. Second, it should have small and light structure compared with old equipments and have high voltage generator unit for X-RAY using inverter. Third, it should be able to send the shot data that is digital detector type without film to doctors in emergency center.

The purposes of this study were to examine the correlations of children's competencies perceived by fathers and mothers, and to investigate differences of children's competencies in relations to characters of the children and that of the parents. The subjects were 225 pairs of father-mother of 7 and of 12 year old children in Daejon. The major findings were as follows. (1) Children's competencies perceived by fathers and mothers were positively correlated with each other. (2) The gender of child affected much on father-perceived esthetic and musical competencies, and on mother-perceived responsible, intellectual, esthetic, and musical competencies. Child's age also had a great effect on father- and mother-perceived esthetic competencies of child. (3) There were no significant differences in children's competencies in relations to characters of parents except in father-perceived responsible competence by fathers' age and in intellectual competencies by income, and in mother-perceived social competences by mothers' job.

지난 몇 십 년 동안 한국에서는 도시의 확장으로 인해 인구 밀집지역에서의 토지이용이 급속하게 변화되었으며, 그 결과 도시의 환경은 악화되었다. 도시화는 도시민에 필요한 녹지의 크기와 수를 감소시킬 뿐만 아니라, 서식처 파괴의 원인이 되며, 적절한 녹지의 배치 또는 배열이 이뤄지지 않을 경우 도시내 생태적 기능의 결핍을 초래한다. 경관변화의 증명과 분석은 토지이용변화의 환경 요소의 인과관계 파악에 중요하다. 원격탐사와 지형정보체계는 토지이용 변화의 경향과 영향을 이해할 수 있어 녹지공간변화 파악에 사용된다. 원격탐사는 동일대상지의 다른 시기에서의 영상자료를 이용해 토지이용의 경년변화를 파악하며 지형정보체계는 이를 저장, 분석에 활용되고 있다. 본 연구는 원격탐사와 지형정보체계를 이용하여, 1989년부터 1998년 동안, 대전광역시의 토지이용 변화를 파악하며 그 원인을 살펴보는데 있다.

Purposes of the study were to find out the joint effects of two salient appearance cues-hair colors and hair lengths on males fashion images, using 729 university students in Daejon city and a Chungnam province. The study was a quasi experiment; the dependent variables were hair lengths(4 levels) and hair colors(4 levels)and the dependent variable was a set of semantic different of scales which was consisted of 40 hi-polar adjectives, The data were analyzed by a factor analysis, 3-way ANOVA, and the results were as follows. Hair lengths effected on the image of five dimensions, salient, social, potency, evaluate and dynamics while hair colors effected on salients, social and potency dimensions. The most significant interaction effect between hair color and lengths were existed on the salient image: For the longer haired males, the color effects became less evident then normal to shorten haired males and it can be concluded that when two salient cues were combined one cue's effect became discounted.

토목공사장에서 암파쇄 작업은 경제성과 안정성에 지대한 영향을 미치는 작업이다. 본 논문은 대전지역에서 수행된 암파쇄 공법 설계 및 시공사례로서, 현장암반의 특성을 고려한 적정발파공법을 선정하기 위하여 대상 지역의 지질현황을 조사·분석하고, 또한 민원이 첨예한 도로개설 공사장에서 시험발파를 실시하여 이를 토대로 암절취 공법을 선정하여 시공한 사례보고이다. 대전지역의 지질은 선캠브리아기의 변성암류와 변성퇴적암류 및 이를 관입한 심성암류와 중생대 화강암으로 이루어져 있는 복잡한 분포를 이루고 있다. 사례연구 대상 현장은 편상구조가 현저한 관입 편상화강암 및 화강암질 편마암으로 구성되어 있었으며, 시험발파 및 분석결과를 기초로하여 25.5m이내 지역은 HRS 등 무진동 파쇄공법의 적용을 제안하였고, 25.5∼36m 범위의 대부분 지역은 진동제어를 할 수 있는 제어발파공법을 권장하였고, 기타 진동 영향권에서 비교적 안전한 것으로 나타난 지역은 소발파공법을 적용하도록 제안하였다. 제안된 안에 따라 설계를 보완하고 시공한 결과 문제의 발생없이 성공적으로 시공이 완료되었다.

Twenty four metal, nonmetal elements and 4 major anions in total suspended particulates (TSP) collected at two sites in Daejon city from october to december in 1991 by a Hi-vol sampler were thoroughly analyzed by Inductively Coupled Plasma/ Atomic Emission Spectrometry (ICP/AES) and Ion Chromatography (IC). These analyzed data were used to perform a receptor modeling using the Chemical Mass Balance (CMB) for the source apportionment of TSP sample. Approximately 60% TSP weight in industrial complex area was influenced by potential industrial sources and 25% was by heating fuels and automobile emissions, whereas a half of TSP in residential area was influenced by surrounding environment and more than 35% of TSP was influenced by heating fuels. The CMB model provided source apportionment results reasonably and scientifically with a minor limitation.

There are various causes for noise production in induction motors, and among them, the noise generated by magnetic vibrating distribution forces have an important meanings. In this paper, the magnetic vibrating distribution forces in squirrelcage induction motors were arranged systematically in the consideration of stator harmonics and it's forces were not considered the effection of airgap eccentricity and deformation. With the application of the finite element method in order to find magnetic flux density and with the calculation of the permeance of rotor node, the magnetic vibrating distribution forces were analyzed.

Dry etching characteristics of indium tin oxide films and etch selectivities over photoresist films were investigated using $Cl_2/HBr$ inductively coupled plasma. From a Langmuir probe diagnostic system, it was observed that while the plasma temperature was kept nearly constant in spite of the change of the HBr mixing ratio, the positive ion density decreases rapidly with increasing the mixing ratio. On the other hand, a quadrupole mass spectrometer showed that the neutral HBr and Br species increased. The etching mechanism in the $HBr/Cl_2$ plasma was analyzed.
