천영기,김진희 한국발달장애학회 2006 발달장애연구 Vol.10 No.1
The purpose of this study was to examine differences between elementary regular teachers and special class teachers about the actual application of Korean traditional play. For this purpose, questionnaires were distributed to 100 regular education teachers and 100 special education teachers in elementary schools. The collected data were calculated by frequency and percentage and were analyzed by x² and t-test. The results of this study were as follows; First, both groups of teachers were low on the variety of play, frequency of actual applications. In addition, special education teachers showed lower application rate and less planning effort than regular education teachers. Second, both groups of teaches showed strong desire to participate in various in-service training for traditional play and wanted to have instructional materials for traditional plays. It was suggested that frequency of education activities using traditional plays should be increased at schools, and that programs which can be adapted in the fields and developmental conditions of children with special needs should be developed. 본 연구에서는 초등학교 일반교사와 특수교사의 전래놀이 활용실태가 어떠한지 알아보기 위하여 일반학급교사 100명과 특수학급 교사 100명을 대상으로 설문조사를 실시하였다. 자료처리는 조사 대상자의 일반사항에 대하여 빈도와 백분율을 산출하였으며, 각 문항별 배경변인별 차이를 알아보기 위하여 x²검정, t검정을 이용하였다. 이에 따른 결과는 다음과 같다. 첫째, 전래놀이 활용종류와 활용시간 측면에서 두 교사집단 간에 통계적으로 유의미한 차이가 없이 모두 낮은 수준이었다. 교사들이 전래놀이 도입의 필요성을 인식하고 있으나 놀이 도구의 부족, 공간 부족, 수업시간 부족 등의 이유로 전래놀이를 제대로 활용하지 않는 것으로 분석되었다. 두 집단 간에 통계적으로 유의미한 차이를 보인 요인들을 보면, 특수교사가 일반교사에 비하여 전래놀이 지도계획의 수립과 실시 측면에서 낮은 비율을 나타냈으며, 교육활동 참고자료도 일반교사는 교육활동 자료집과 전문서적을, 특수교사는 일반적으로 알고 있는 전래놀이를 주로 이용하는 것으로 나타났다. 특히 전래놀이를 교육활동으로 실시한 평균횟수는 일반교사가 특수교사보다 현저하게 높았으며, 특히 40세 이하의 특수교사 집단이 가장 낮은 것으로 나타났다. 따라서 전래놀이관련 교육기회 및 연수기회를 제공하고 전래놀이자료의 개발과 보급에 많은 노력을 기울이는 것이 필요하다. 또한 장애를 지닌 아동의 영역별, 발달단계별로 적용 가능한 프로그램의 개발에도 많은 노력을 기울여야 하겠다.

수소와 불활성 가스 중 일산화탄소, 이산화탄소, 메탄 제거에 관한 연구 -연료전지에의 적용 가능성-
이택홍,천영기 한국수소및신에너지학회 2004 한국수소 및 신에너지학회논문집 Vol.15 No.3
The purpose of this paper is, based on the theoretical background of the principle of gas purification and absorption, and the absorbing ability of metals, to syudy the efficiency of gas purification of inorganic gases using Zr alloys, so as to contribute to the IT industry. To produce and distribute gas with high purity and ultra-high purity, different types of gas purifier are currently being used: distillation type, getter type, catalyst type, absorption at low-temperature type, and membrane separation equipment. From the different purification methods mentioned above, the getter type gas purifier is capable of not only high performance and capacity but also P.O.U(Point Of Use) method. The key of the getter type gas purifier is its efficiency of gas purification, which is the subject chosen for this study.

In the production of hydrogen from various sources like cracking of LPG, LNG, Crude oil, or alkaline water electrolysis, the things that we keep in mind is the entrapment of unexpected impurities in the stream of produced H2. If it is true that we are not able to produce 100% pure H2, then subsequent procedure is the elimination of the impurities and the determination of the concentrations of each constituents in H2 stream. By the way, each country has different constituents in its fuels and unavoidablely it was cost/economy debates between coutries. Thus, in this paper, our goal is to provide current international issues for hydrogen production.

Hydrogen is a clean, endlessly produced energy and it is easy to store and transfer. So, hydrogen is regarded as next generation energy. Among various ways for hydrogen production, the way to produce hydrogen by water electrolysis can effectively respond to fossil fuel’s depletion or climate change. As interest in hydrogen has increased, related research has been actively conducted in many countries. In this study, we analyzed the performance characteristics and safety of water electrolysis system. In this study, we analyzed the performance characteristics and safety of water electrolysis system. The items for safety performance evaluation of the water electrolysis system were derived through analysis of international regulations, codes, and standards on hydrogen. Also, a prototype of the overall safety performance evaluation station was designed and developed. The demonstration test was performed with a prototype 10 Nm3/h class water electrolysis system that operated stably under various pressure conditions while measuring the stack and system efficiency. At 0.7MPa, the efficiency of the alkaline water electrolysis stack and the system that used in this study was 76.3% and 49.8% respectively. Through the GC analysis in produced H2, the N2 (5,157ppm) and O2 (1,646 ppm) among Ar, O2, N2, CO and CO2 confirmed as main impurities. It can be possible that the result of this study can apply to establish the safety standards for the hydrogen production system by water electrolysis.
