학교단위 민주적 의사결정과 교사의 갈등지수가 교사효능 감과 학교만족도에 미치는 영향: 서울형혁신학교와 일반 학교의 비교를 중심으로

연구목적: 본 연구는 ‘학교단위 민주적 의사결정(DDS)’와 교사의 민주적 의사결정 갈등지수(CIDD)가 교사효능감과 학교만족도에 영향을 주는지 알아보고자 하였다. 연구방법: 학교풍토와 갈등지수, 교사효능감, 학교만족도를 측정하는 질문지를 초․중등학교 일반학교와 혁신학교에 배포하였고 총 877부를 기본 자료로 활용하였다. 연구결과: 학교단위 민주적 의사결정 풍토와 갈등지수가 높으면 교사효능감과 학교만족도가 유의미하게 높았다. 그러나 선행연구에 의하면 높은 갈등은 교사효능감과 학교만족도에 부정적인 변인이라고 여겨지고 있었다. 혁신학교는 일반학교보다 높은 민주적 의사결정 풍토을 보였고 학교만족도 또한 높았다. 논의 및 결론: 현재 학교에서 교사들 간 충돌은 적절히 조절되고 있으므로, 학교혁신의 과정에서 파생하는 교사 간 갈등이 있다고 할지라도 혁신학교 뿐만 아니라 일반학교에서도 혁신정책들을 지속적으로 추구할 필요가 있다. 민주적 의사결정에서 나타나는 갈등은 교사 자신의 비판적 성찰과 성장에 도움이 될 수 있다. Purpose: The research analyzed how much both ‘Democratic Decision-making of School unit(DDS)’ and ‘Conflict Index of Democratic Decision-making(CIDD)’ could cause effects on self-efficiency and school satisfaction of teachers. Method: The questionnaires inquiring DDS, CIDD, self-efficiency of a teacher, and school satisfaction of a teacher were distributed and 887 of elementary or secondary school teacher responses in general schools as well as Hyukshin schools were summed. Results: Both high DDS and CIDD could guarantee high self-efficiency and school satisfaction. However, CIDD was regarded as a negative variable for self-efficiency and satisfaction of teachers. Hyukshin schools have higher DDS and school satisfaction than general schools. Conclusion: It was proven that in spite of conflict among teachers during school innovation, Hyukshin school as well as general schools might need to pursue innovative policies continuously while the conflicts would be controlled moderately.

3-D structure is created at the tunnel face in all tunnelling. Accordingly, the ground around the tunnel under construction shows three dimensions deformational behavior due to the transverse and longitudinal arching effects. In order to obtain the realistic results of these the tunnel behavior from the numerical analysis, actual construction measures and their sequence must be taken into account. In particular, the excavation and installation of support and lining are important tunnel construction parameters. Despite these three dimensionalities encountered in tunnelling, a three-dimensional analysis is often not necessary. Instead, a two-dimensional model can be substituted because of the size and complexity associated with a 3-D model and calculation times to perform a 3-D analysis. The simulation of 3-D conditions by a 2-D model requires experience and the understanding of the relationship between theses two models. Load distribution ratio is used to the 2-D analysis for the consideration of the effects of the tunnel advance in three dimensions in Korea. However, constant load distribution ratios have been assigned for 2-D analysis even if the conditions for tunnel design are different. This paper presents the results of the evaluation of load distribution ratios through a three-dimensional tunnel analysis for the different ground formation and compares the cases of load distribution ratios applied actual tunnel design in Korea.

In reinforced concrete carbonation of concrete leads to activation of the reinforcement, and hence to initiation of corrosion. The objective of this study is to acquire the reinforcement corrosion rate according to carbonate. As a result of carbonation accelerating experiment with using effect of wet-dry and 15% concentration of CO2, the carbonation rate shows very distinct difference according to w/c ratio. OPC-40 estimated no carbonation depth, whereas OPC-60 estimated rapid the carbonation rate. The comparative analysis of the carbonation rate according to species of cement shows fastest FAC-20. Also, highly W/C ratio's concrete shows low half-cell potential value and fast corrosion rate. During period for 14 weeks, corrosion rate was not severe. So, It can be determined that only carbonation attack on concrete doesn't severly deteriorated except very poor qualitified concrete..
