남궁정,한아름,문형태 한국생태학회 2008 Journal of Ecology and Environment Vol.31 No.4

Weight loss and nutrient dynamics of oak and pine leaf litter during decomposition were investigated from December 2005 through June 2008 at Mt. Worak National Park as a part of National Long-Term Ecological Research Program in Korea. The decay constant (k) of oak and pine leaf litter were 0.314 and 0.217, respectively. After 30 months decomposition, remaining weight of oak and pine leaf litter was 45.5% and 58.1%, respectively. Initial C/N ratio of oak and pine leaf litter was 53.4 and 153.0, respectively. Carbon % of initial oak and pine leaf litter was similar with each other; however, nitrogen content of initial oak leaf litter (0.85%) was greater than that of initial pine leaf litter (0.33%). N and P concentration in both decomposing leaf litter increased significantly during decomposition. There was no net N and P mineralization period in decomposing pine leaf litter. K, Ca and Mg concentration in both decomposing leaf litter showed different pattern with those of N and P. After 30 months decomposition, remaining nutrients in oak and pine leaf litter were 97.7 and 216.2% for N, 123.2 and 216.5% for P, 39.3 and 44.8% for K, 47.9 and 40.6% for Ca, 30.7 and 51.2% for Mg, respectively.

남궁정,박미정 한국실과교육연구학회 2021 실과교육연구 Vol.27 No.2

본 연구는 중학교 가정교과의 자유학기제 주제선택활동에서 활용할 수 있는 자아존중감 향상을 위한 그림책 스토리텔링 프로그램을 개발하는 데 목적이 있다. 이를 위해 자아존중감 관련 선행연 구를 분석하여 자아존중감의 하위영역을 총체적 자아존중감, 가정적 자아존중감, 친구관련 자아존 중감, 사회적 자아존중감의 4가지로 설정하고 그에 맞는 그림책 19권을 선정하여 분석하였다. 설 정한 자아존중감 하위영역에 따른 세부 내용을 추출하여 그림책 스토리텔링에 적합한 학습 요소를 구성하고 스토리텔링 요소를 적용하여 수업 전체 과정과 그에 따른 교육기법을 선정하여 수업전략 을 설계하였다. 이러한 학습 요소와 수업전략을 기반으로 자아존중감의 4가지 하위영역별로 각각 4차시, 총 16차시의 ‘그림책을 통해 만나는 소중한 나’의 교수 학습 과정안과 교수 학습 자료인 워 크북을 개발하였다. 마지막으로 개발한 교수 학습 과정안과 교수 학습 자료인 워크북에 대한 전문 가 평가를 수행하여 타당도지수(Content Validity Index, CVI) 산출을 통해 전체 프로그램의 CVI는 1.0, 차시별 프로그램의 평균 CVI는 0.98로 타당성을 검증 받았다. 본 연구는 청소년이 자신을 존중하고 사랑하는 힘을 길러 행복한 삶을 살아갈 수 있는 근간을 마련하고, 가정과 자유학 기제 주제선택활동으로서 그림책 스토리텔링 교육의 가능성을 확인한 것에 의의가 있다. The purpose of this study is to develop a picture book storytelling program to improve self-esteem that can be used in subject selection activities in the free semester system of middle school home economics. To this end, prior studies related to self-esteem were analyzed, sub-areas of self-esteem were set, and picture books were selected and analyzed. After extracting the detailed contents according to the self-esteem sub-areas, the learning elements suitable for picture book storytelling were composed, and the entire course of the class and the educational technique according to it were selected to design a teaching strategy. Based on these learning elements and teaching strategies, the 16th teaching/learning process plan and teaching/learning materials (workbooks) for “The precious I met through picture books” were developed. Finally, the validity of the developed teaching/learning process and teaching/learning materials (workbook) was verified by experts. This study is meaningful in establishing a foundation for adolescents to live a happy life by cultivating the power to respect and love themselves, and to confirm the possibility of picture book storytelling education as a subject selection activity for home economics.

In today's knowledge and information society in which a tremendous amount of information is digitalized and provided, modern poetry education cannot be one exception. According to a recent announcement from the Ministry of Education, Science, and Technology, all the current paper textbooks will be replaced with digital ones in future. The advent of digital textbooks era is to meet the demands of the times and environment and involves a continuous evolution into new forms according to the development of science and technology. Getting prepared for those changes, researches on literary education should be able to offer future directions for digital textbooks with a focus on the learners' enjoyment of poetry and literary experiences. In that vein, this study set out to propose an idea of turning modern poetry education into a digital textbook by utilizing interactive storytelling, showing that digital textbooks could induce interest, commitment, and new effects with regard to modern poetry education and study. It then introduced successful cases of educational content that utilized interactive storytelling, pointed out problems with cyber home study, a digital teaching material, and examined the interactive elements required for turning modern poetry education into a digital textbook. In particular, the investigator drew a blueprint for modern poetry education applicable in a digital textbook by giving various examples that used a branch narrative structure. Digital textbooks can offer answers to how to teach poetry to learners in today's environment and accordingly should be developed in a way that helps to preserve the nature and heritage of poetry, allow the students to enjoy the truth and value of poetry, and achieve the educational objectives. It is beyond a doubt that digital textbooks will bring a positive turning point to modern poetry education.
