본 연구에서는 '연소 전후 질량 보존'개념의 학습에서 변칙 사례의 개수와 표현 방식이 학생들의 인지 갈등과 개념 변화에 미치는 효과를 조사하였다. 남녀 공학 중학교 2학년 128명을 대상으로 선개념 검사, 변칙 사례에 대한 반응 검사, 개념 검사를 실시하였다. 변칙사례는 개수(1개/2개)와 표현 방식(글/글+그림)에 따라 네 종류로 제시하였다. 연구 결과 변칙 사례를 두 개 읽은 학생들이 하나 읽은 학생들보다 더 많은 인지 갈등을 일으켰다. 그러나 변칙 사례의 표현 방식에 따른 인지 갈등 유발 정도는 유의미한 차이가 없었다. 개념 검사 점수에 이원 변량 분석 결과, 변칙 사례의 특성에 따른 차이는 유의미하지 않았다. In this study, the effects of the number and the presentational type of anomalous data on students'cognitive conflict and conceptual change in studying 'conservation of mass before and after combustion'were investigated. The subjects were 128 eighth graders in a co-ed middle school. A preconception test, a test of response to anomalous data, and a conception test were administered. Four types of anomalous data varying the number (one/two) and the presentational type (text/text+figure) were presented. The results indicated that students with two anomalous data showed more cognitive conflicts than those with one. However, no significant differences in the degree of cognitive conflict were found by the presentational types of anomalous data. The ANOVA results indicated that there were no significant differences by the characteristics of anomalous data in the conception test scores.

The purpose of this study is to plan a environment for creative education in university campus. According to the literature review, the necessity of improvement of educational program and physical environment is increasing because of rapidly social and industrial structure change. In this aspect, G university decided to make space for creative education utilizing unused space in campus. The space design concept was established as a cell based on the fact that the educational space was a place where students grow up and was named GNU IDEA Factory. The planning site was decided on the existing piloti to solve problems of lack budget and space. This space consisted of rooms for creative education, autonomous students' activity, and exhibition and was designed by organistic structure. In conclusion it was thought that GNU IDEA Factory would be a case of environment for creative education and activity if it was supported proper program and usable equipments.

The purpose of this study is to suggest the application method of CPTED for safer schools. For the evaluation of the school safety, we invented the school survey checklist based on the principles of CPTED such as natural surveillance, access control, maintenance, and activity support. The checklist is consisted of three parts of schools including boundary, outside of the building, and inside of the building. For the field survey of schools, the 30 schools(elementary, middle, and high school) were selected in Seoul and Kyong-gi area as the crime rate. The result of this study shows the safety score for the most of schools were not satisfied. In addition, we realized the diverse strategies to enhance the school safety should be applied to schools in terms of CPTED. The detailed findings and policy implications will be discussed in the context.

The cytologic finding of proliferating trichilemmal tumor is not well documented and have difficulties in the cytological analysis of the fine needle aspirates. This rare dermatopathologic entity may be encountered during aspiration biopsy of subcutaneous masses, and is, occasionally, confused with other neoplasm, particulary squamous carcinoma owing to its close cytological resemblance. We report a case of proliferating trichilemmal tumor in the left breast. The patient is a woman and had a lump in the breast for 20 years. Fine needle aspiration revealed a few small clusters of squamoid cells in the background of amorphous and calcified material. After excisional biopsy, the mass was confirmed as proliferating trichilemmal tumor. The main cytologic features discriminating squamous cell carcinoma were bland nature of epithelial cells, absence of atypical dyskeratotic cells, and rich amount of amorphous material.
