The purpose of this study was to analyze of the effects of instructional supervision emphasizing reflective thinking on science teaching of elementary teachers. The participants in this study were two teachers. This study was divided in former, middle, and later periods, and consisted of monitoring their own teaching, interviewing, journal writing, discussion with peer teachers and teacher training. Data included descriptions of nine science classes, nine interviews, seven journals and the journals of the researcher. Data analysis tools were the frameworks of the questions, feedback, teaching methods, elements of teaching behavior, and reflection levels. This study employed qualitative research, analysis of the frequency of data, and quoting of descriptions related to the result. The results of this study were as follows: First, teachers showed mainly technical reflection, but changed to show more practical reflection, and critical reflection in the later period of instructional supervision. Second, instructional supervision emphasizing reflective thinking on science teaching for elementary teachers meaningfully changed the question, feedback, teaching methods and teaching elements of teachers. From the results of this study, instructional supervision emphasizing reflective thinking on science teaching for elementary teachers can be considered an effective method in improving teaching elementary science, and instructional supervision used in this study made possible the higher level of reflection and appropriate teaching behavior.

본 연구는 현행 초등학교에서 이루어지고 있는 서술형 평가의 유형과 문제점을 분석해 보고 2007개정 교육과정에 따른 수학과 서술형 예시 평가 문항을 개발해 보는데 목표가 있다. 학교에서 시행되고 있는 평가 자료의 분석은 수학교과서, 국가수준 학업성취도 평가지, 서울시 교육청 보급 2010 장학자료집, 서울시내 학교에서 시행되고 있는 평가 문항을 분석해 보았다. 그리고 예시 서술형 평가 문항개발은 2007개정 교육과정에 따른 수학과 4학년을 대상으로 하였다. 평가 문항 분석의 결과는 문항 유형이 단순하고 교과서와 장학자료집의 수준을 벗어나지 못하고 있으며 창의성 영역의 평가는 거의 이루어지고 있지 않았다. 서술형 예시평가 문항의 개발은 수학과의 내용영역과 인지적 영역뿐 아니라 교육계의 화두가 되고 있는 창의성 영역까지 평가내용으로 포함시키고자 노력하였으며 영역별 1-2 문항을 개발하였다.

South anchorage(AN1, Myodo side) of supension bridge between Myodo and Gwangyang is designed as rock anchorage with 36m anchor length using the resistance of rock mass in Myodo. Checking the overall stability of the anchorage, we considered rock joints, bedding planes, fault zones and condition of rock structure in situ by analysis results for photo-lineaments, aerial photograph interpretation and drill-hole logs are considered. This anchorage consists of an access shaft, adit, and the upper and lower concrete bearing plate to introduce pre-stressing force into rock mass.

The purpose of this study was to conduct a survey and analysis of 249 children of the Fragment Love Sharing Society to find out the impact of the association program on children. Correlation analysis was conducted using the SPSS Statistics 23 program to confirm the relationship between scholarship students and scholarship management institutions, and regression analysis was conducted to confirm the impact of the relationship between scholarship students and the scholarship management institution. According to the analysis, the higher the satisfaction level of scholarships, the higher the level of career proficiency and yesterday's happiness, and the more satisfied the child is with the benefits of the crumb scholarship, the higher the sense of self-respect, career maturity, and yesterday's happiness. Based on these findings, support measures were discussed for children with ties.

The present study examined the relationships between work related flow (i.e., absorption, work enjoyment, and intrinsic work motivation) and role conflict causes (i.e., teacher's belief, teaching and interaction with young children, comradeship, relationships with parents, workload, supervision, and social awareness of the job). A canonical correlation analysis was performed on the data from a sample of 154 childcare teachers. The results are as follows (1) there was a reciprocal-causal relationship between teachers' role conflict causes and their work-related flow; (2) canonical function 1 showed that absorption and work enjoyment are strongly associated to a teacher's belief and supervision of conflict causes; and (3) canonical function 2 showed that intrinsic motivation has a relatively strong relationship with workload and supervision of conflict causes. It can be concluded that it is important for childcare teachers to have sufficient job resources to promote their flow at work. Further research is needed for investigation of teacher's flow at various conditions of work.

In this study, a carbon film derived from a polymer/lignin composite precursor was produced by a carbonization cycle with a controlled temperature profile. The feasibility of successful formation of the carbon film using the carbonization cycle was monitored. The adsorption behavior of the carbon film toward various molecules, such as nonpolar and polar organic molecules, and dyes was investigated using ultraviolet/visible (UV/Vis) spectroscopy compared with that of carbonized lignin. Cyclic voltammetry (CV) analysis proved that a robust carbon film was prepared by the carbonization cycle. It was also demonstrated that the carbonized lignin and carbon film showed adsorption capability toward all types of organic molecules, in particular organic dyes, owing to the carbonized lignin. This work provides important information for future relevant research.

The economic growth brought the demand of bridge connected to island and land increasingly in Korea. Therefore, Civil engineer has faced a lot of problem to be considered such as structural stability, economic feasibility and constructional method. At the bridge site to be constructed, the depth of water is about 24m, the thickness of weathered rock overlaying bed rock is thicker than 36m. If open caisson foundation is supported in bed rock, the hight of foundation is about 60m. It is difficult to construct in these conditions. If open caisson foundation is supported in weathered rock, the size of the foundation should be increased. And If we apply the pile foundation, the higher construction cost will be needed. Under the circumstances, we need a new foundation type-composite foundation that is consisted of open caisson and cast-in-place piles. Because the design concept of composite foundation is not presented in Korea Bridge Design Standard, we are willing to clear the bearing behavior of composite foundation by numerical analysis in this paper.
