This study aims to develop educational materials focused on data visualization as one of the types of scientific models using oceanic data. Earth science subjects have a higher proportion and role in data visualization than other subjects. Data visualization in Earth Science has long been essential in deriving meaningful information using extensive databases collected over a long period. As a result of the 2015 Revised National Curriculum Earth Science Ⅱ textbooks' analysis, the inquiry related to tide was limited to presenting a simple form of 1-D time series data. No specific activities using various digital tools have been composed constructively to teach the tide-related contents and classroom activities. This suggests a necessity to develop a data visualization program using real-time oceanic tide data. This study developed a program of specific methods for data visualization based on Python. The detailed program consisted of a few tidal data visualizations such as 1-D time series visualization, converted 2-D data from 1-D time series data, and tidal variations in the form of a Hovmöller diagram with a time(hour)- to-time(day) plot. This plot can be used as scientific inquiry activities to understand tidal phase delay during the day. Considering this, it is expected that the teaching and learning materials developed in this study will be extensively used to form scientific concepts related to tide variations, implement effective inquiry methods, and data visualization using online tools. 이 연구의 목적은 해양 데이터를 활용하여 과학적 모델 유형 중 하나인 시각화 자료를 구성할 수 있는 수업 자료를 개발하는 것이다. 지구과학 과목은 다른 과목에 비해 시각 자료의 비중과 역할이 높은 편이며, 장기간 수집된 빅데이터를 활용해 의미 있는 정보를 도출하려면 데이터 시각화가 필수적이다. 2015 개정교육과정 지구과학 Ⅱ 교과서 분석 결과, 조석 단원에 수록된 실시간 자료 활용 탐구 활동으로 산출되는 시각 자료 중 그래프 형태는 1-D 시계열 형태로 제시되어 있고 다양한 디지털 도구를 활용하는 구체적 활동이 제한되어 있었다. 수업 자료는 PDIE모형을 기반으로 개발하였고, 현직 교사 대상 설문 조사를 통해 자료 개발 방향과 내용 구성에 대한 의견을 수렴하였다. 수업 시간에 교과서와 함께 디지털 도구를 활용하여 데이터 시각화 활동을 할 수 있는 구체적 방법을 제시하였고 탐구 활동에 유연하게 활용할 수 있는 형태로 제작하였다. 수업 자료의 세부 내용은 조위 데이터의 1-D 시계열 형태 시각화, 시간과 일 단위의 2-D 데이터 형태로의 변환 과정과 시각화, 2-D 자료의 패턴 분석을 활용한 조석의 위상 지연에 관한 과학적 탐구 활동이며 파이썬 프로그램으로 구성하였다. 현직 교사를 대상으로 수업 자료 실습 연수를 실시한 결과, 시각화 과정과 탐구 활동을 구성하는 과정에서 효용성이 있음을 확인할 수 있었다. 연구에서 개발된 교수 학습 자료는 조석 단원과 관련된 과학적 개념 형성 및 효과적인 탐구 방법 구현, 온라인 도구를 활용한 데이터 시각화 수업에 널리 활용될 것으로 기대된다.

김수란 대한영상의학회 1997 대한영상의학회지 Vol.36 No.2
Purpose : To describe the HRCT and pathologic findings of squalene- induced lipoid pneumonia in rabbits. Materials and Methods : Three ml of squalene was instilled into the trachea between the second and the third tracheal ring in 16 rabbits. Serial HRCT scans were obtained on day 4 (n=8), at l week (n=7), 2weeks (n=1), 4weeks (n=1), 6weeks (n=2) and 20weeks (n=1) after squalene instillation. With sacrifice of the rabbits pathology was reviewed at 1 week (n=3), 4weeks (n=3), and 6weeks (n=4) after CT scans. Results : Lipoid pneumonia was induced in 8 rabbits; lesions were distributed mainly in the dependent posterior lung. On serial HRCT scans, airspace consolidation, as seen on an air-bronchogram, and nodular opacities were early findings; these gradually diminished and with time were replaced by nodular & linear opacities. Histologically, pulmonary fibrosis appeared one week after squalene instillation and progressed over time. Alveolar septal thickening and cuboidal change of the alveolar lining epithelium were more prominent at week 6. Conclusion : The early change of squalene-induced lipoid pneumonia in rabbits is the proliferation of intraalveolar macrophage, which is responsible for air-space consolidation with air-bronchograms on HRCT. Nodular and linear opacities on HRCT are due to the appearance of pulmonary fibrosis on week after squalene instillation, and its subsequent progression.

Urban regeneration is taking place through the renovation of abandoned large-scale industrial facilities, as the cultural, economic and technological responses to cope with the recent rapid urbanization and the new demands of the fourth industrial revolution era become more important. This study analyzed the case of effective renovation of large-scale idle space all over the world. In addition to analyzing the architectural characteristics of these cases, historical background, significance of renovation, methods, space composition, and programs were compared and their meaning in the urban context was summarized. The concrete method of renovation was mainly used for preserving the symbolic facilities and the facade of the existing building, and modifying the interior and exterior so as to contain new functions. Since the existing buildings are large, efforts have been made to change the internal space structure while maximizing the existing structure rather than enlarging. The effect and significance of such a large-scale idle space renovation can be summarized as preservation of history, supply of large-scale cultural and economic facilities, and revitalization of the city. The purpose of this study is to analyze the trend and characteristics of renovation of a large-scale idle space, intended to summarize effective planning elements for future renovations of large-scale idle space.

김수란 한국교육방법학회 2015 교육방법연구 Vol.27 No.2
The purpose of this study was to verify how the teacher positive support affects the learners' questioning as one of the ways to promote learners' questioning. In order to reach the objective, 694 university students were selected, and a hierarchical regression analysis was conducted to see if there are moderating effects of teacher positive support on the relationship between learners’ internal hesitation of questioning and question asking. As a result, each step of the regression model appeared to have statistically significant meaning and confirmed that the teacher positive support has a buffering effect, which lowers the negative effect of the learners' internal hesitation on question asking. The result of this study shows the critical role of teachers on promoting students to question. Furthermore, it can be a meaningful empirical data for improving the environment and teaching method to promote learners' questioning. 본 연구는 학습자의 질문을 촉진시키는 방안 중 하나로 교수자의 긍정적 지지가 학습자의 질문에 어떠한 영향을 미치는지 검증하고자 하는 것이 목적이다. 이를 위해 대학생 694명을 대상으로 학습자 내적 질문저해요인과 실제 질문간의 관계에서 교수자의 긍정적 지지가 조절효과가 있는지 위계적 회귀분석(Hierarchical multiple regression)을 실시하였다. 분석 결과, 회귀모형의 각 단계 마다 통계적으로 유의하였고, 조절변인인 교수자 긍정적 지지는 학습자 내적 질문저해요인이 실제 질문에 미치는 부정적인 영향을 완화시키는 효과(buffering effect)가 나타남을 입증하였다. 이밖에도 학습자 내적질문저해요인들 중 인지적 특성에서 유의한 조절효과가 있음을 확인하였다. 이러한 본 연구 결과는 학습자의 질문행동에 있어서 교수자가 중요한 역할을 함을 인식하게 해주며, 학습자 질문을 촉진하기 위한 교수방법 및 교육환경 개선 방안을 수립할 때 유용한 경험적 자료가 될 수 있을 것이다.
