대학 사회봉사 원격원예치료교육 프로그램 개발과 그 효용성 검증에 관한 연구
박성열,남민우,이은환,주민호 한국농·산업교육학회 2002 농업교육과 인적자원개발 Vol.34 No.4
The purposes of this study were to identify the effectiveness of distance horticultural therapy education system for university outreach programs. One 10-minite sample distance horticultural therapy lesson was developed and used as a experimental tool to determine whether it could be effective for university outreach program. Since the main methodology was the experimental design, the survey group was divided into two groups, experimental and control group. The groups consisted of 50 subjects each.

Three dimensional carbon nanomaterial reinforced composite aerogel was fabricated using a freezedrying method. Graphene nanoplatelets (GNPs) were used as the reinforcement and poly vinyl alcohol (PVA) as the organic binding material to produce the composite aerogel. Two different methods were employed to control the internal structure of the aerogel: a variation of solvent composition and the formation of cross-linking. The internal structure of the aerogel was affected by the types and composition of the solvent. In addition, the subsequent cross-linking of the aerogel influenced the morphology and physical properties. It is expected that this study can provide a simple and efficient way to control the internal structure and resulting properties of the GNP aerogel.

‘The Flipped Learning’ : Research on the Development of a Hybrid Instructional Model
박성열,임걸 한국지식정보기술학회 2014 한국지식정보기술학회 논문지 Vol.9 No.1
Using recent advanced information technologies, a “flipped learning” instructional model was developed for this study to enhance the effectiveness and efficiency of instruction. A flipped learning generally refers to a hybrid learning environment where learners learn online at home and conduct academic activities in the classroom or a physical place. In order to develop an instructional model, development principles, component, and contents were investigated. By the participation of three experts on the subject for comments and feedback and a pilot study for eight weeks, the validity was examined for model elaboration. As a result, the 8C instructional model for on- and off-line learning are presented: construction, connection, communication, coordination, confirmation, clarification, collaboration and completion. Based on the structured flipped learning instructional model, specific strategies are expected by further empirical research.
