본 논문은 지역아동센터 파견 아동복지교사의 직무 만족도 및 적성/직업 인식도를 파악하고, 이를 바탕으로 앞으로 보다 나은 아동복지정책의 기초 자료를 제공하고자 하였다. 먼저 연구대상자의 인구통계학적 특성에 따른 파견 아동복지교사 직무만족도의 인식차이는 성별에 따라서는 상사와의 관계(p<.01), 파견 아동복지교사직에 대한 만족(p<.01), 제공지식정보에 대한 만족(p<.05) 및 전체적인 파견 아동복지교사의 직무만족도에 대해서 유의한 인식의 차이가 나타났다. 적성 및 직업인식도에 대한 인식조사결과, 보다 나은 직장을 얻기 위하여 현재 노력하는지 여부는 학력에 따라서 다소 유의한 인식의 차이가 나타났다. 파견 아동복지교사에 대한 긍지는 현재의 직업에 뚜렷한 사명감과 목표 의식을 가지고 있다는 의견은 27.5%로 나타나 파견 아동복지교사에 대해서는 학생교육을 통한 즐거움과 보람을 통하여 긍지를 느끼는 것으로 인식하였다. 지역아동센터 아동지도프로그램 운영상 어려움은 교육교재부족과 설비부족, 부모님의 참여와 이 해부족을 가장 문제점으로 인식하였다. This thesis is to figure out the job satisfaction and aptitude/vocation recognition of the child welfare teachers dispatched to Region Children Center and provide the basic data for the better children welfare policy in future based on it. First, as for the difference of recognition in the job satisfaction of the child welfare teachers dispatched by the population-statistic property of the research objects, there appeared a meaningful difference by the gender concerning the relation with seniors(p<.01), satisfaction with the office of the child welfare teachers dispatched(p<.01), satisfaction with provided knowledge information(p<.05) and the whole job satisfaction of the child welfare teachers dispatched. As the result of the survey of the recognition on aptitude and job understanding level, there appeared some meaningful differences by the school background on whether or not currently to make efforts to get a better job. In the matter of the pride as to the child welfare teachers dispatched, 27.5% of opinion givers had a clear mission and an objective sense about a current job, and the child welfare teachers dispatched recognized that they felt pleasure and value through the education of students. They understood the difficulty of the management of the children instruction program of region children center in the biggest matters such as the insufficiency of education materials and facilities, and the insufficiency of parents' participation and understanding.

Hydrogen production from photocatalytic water splitting by non-noble-metal photocatalysts is considered to be the most promising solution to the world energy crisis issues. Herein, a CuO-NiO-ZrO₂ composite with remarkable photocatalytic water reduction activity has been successfully fabricated via a wet chemical route. The crystallinity, morphological, optical characteristics, and photocatalytic hydrogen production of the composite were investigated by XRD, TEM with SAED, and UV-Vis. The results of the XRD study affirmed that the nanocomposite comprises cubic, monoclinic and tetragonal phases. TEM with SAED and EDS analysis demonstrates the surface morphology and formation of the composite. The optical bandgap of CuO-NiO-ZrO₂ nanocomposite is calculated through UV-Vis analysis. The unique morphology, significantly improved charge carrier separation, and synergistic effects of the composite system should be responsible for the excellent photocatalytic activity. These findings propose a new unexplored avenue for the fabrication of highly active and low- cost photocatalyst for practical H₂ generation via photocatalytic reduction.
