본 논문에서는 월드와이드웹에 기반한 학습자 중심의 통합 가상교육시스템 CyberClass를 설계하고 구현한 방법을 소개한다. 기존의 가상교육시스템은 학습자 중심의 상호작용 유형을 분석하여 이에 따른 적당한 상호작용 모델을 제시하지 않고 기능면에서의 사용도구 및 방법만을 제시함으로써 각 기능들이 자연스럽게 통합되지 못하였다. 따라서 전통적인 교육 방식인 강의실 수업에 참여한 학습자들이 가지는 현장감이나 친밀감에서 오는 커다란 교육적 이득을 제공하지 못하였다. 본 논문에서 개발한 가상교육시스템 CyberClass는 학습자 중심의 상호작용유형을 분석하고 이를 기반으로 상호작용모델을 제시한다. 그리고 제시된 모델에 기반하여 학습자와 교수, 학습자와 학습자 나아가 학습자와 가상교육시스템간의 상호작용에 기반한 시스템을 설계하였다. 따라서 학습자의 상호작용 모델에 기반함으로써 학습 참여도나 학습 능률의 향상을 기대할 수 있다. CyberClass는 학습자 중심의 상호작용을 위해 비동기공유 기공과 동기고유 기능을 모두 지원한다. 이들의 공유 기능들은 유기적으로 결합하고 직관적인 학습자 인터페이스를 제공함으로써 학습자에게 기능의 다양성에 따른 학습의 부담을 줄이고 자연스런 학습과정이 유도되도록 하였다.

The purpose of this study was to investigate activity participation level and functional disability based on ICF for the elderly aged over 65 years. Subjects were 100 senior citizens. We performed data collection using Korean Activity Card Sorting(KACS) and World Health Organization Disability Assessment Schedule 2.0(WHODAS 2.0). Data were analyzed using descriptive statistics, Pearson's correlation, multiple regression. As a result of the survey of activity participation levels, retained level of activity participation of instrumental activity was highest at 75.06%. Among the WHODAS 2.0 sub-domain, 'getting along with people', 'participation in society' had the most difficulties and 'self-care', 'life activities' were the lowest. An analysis of the correlation between the activity retention rate and functional disability showed that there was a significant negative correlation. Significant factors influencing functional disability were activity participation level of social activity, instrumental activity and main work(retirement). We confirmed that activity participation level was important factor on functional disability. Further, we need standardization study for generalization.

The principle objective of this study is to determine factors affecting social participation for physically disabled people with musculoskeletal conditions (spinal cord injury, muscular dystrophy, osteogenesis imperfecta, rheumatoid arthritis) in South Korea using ICF relevant categories of the international classification index by WHO. The subjects of this study 352 people with physical disabilities, the data were collected using ICF component(body functions, body structures, activities and participation and environmental factors) and the relevant categories deprived from ICF core sets. The collected data were evaluated with descriptive analysis, ANOVA, correlation analysis, and multiple regression analysis. The results of this study can be summarized as follow. The mental function, Neuromusculoskeletal and movement-related functions, Genitourinary and reproductive functions, Skin and related structures, Learning and applying knowledge, General tasks and demands, and Mobility positively influenced social participation in people with musculoskeletal conditions. However individual factors and environmental factors didn't statistically significant affect on social participation. The implications of the study is to examine by ICF components of universal approach on disability study and utilized the relevant ICF categories as measurement tools.

A demand for user's participation in the designing process, which is called the participation design, is increasing with social change. Practically, however, there is lack of researches on the improvement of the problem in actual design development and participation design effect. In order to understand the field-based participation design effect in view of user's change of awareness on participation design, this study carried out a survey on the change of awareness through a design workshop in which all stakeholders have participated on the subject of agricultural direct sales facilities as a part of participation design programs. Many references were reviewed first to understand the participation design principles and their current research trend. Next, the questionnaire was developed using an effectiveness verification model for an effective analysis. A design workshop as one of the participation design programs was organized and applied for the field response. In order to analyze the effect, the survey on participants' change of awareness was carried out before and after the program. The survey questionnaires were about motivation, knowledge, recognition, function, and participation and asked the design study graduates. The participation design effect was supplemented by additional open questions. As a consequence, the participants in the participation design program showed the noticeable effect in knowledge and function about the agricultural direct sales facilities. It was found that they were also highly satisfied with the participation design result and they recognized an importance of collaboration. This study also showed that a sufficient time schedule considering agricultural village life should be given for a smooth operation of the program and also a working environment is necessary for designing work.

The purpose of this research was to identify the components of scaffolding in open inquiry and to explore the functions of teachers' scaffolding, which is necessary to support students' open inquiry. In order to identify scaffolding components, at first, we conducted a survey using a questionnaire on what students think about open inquiry on 110 students who performed open inquiry in two middle schools, and then carried out factor analysis based on the survey results. It was attempted to investigate students' perception through focus group interviews corresponding to scaffolding components that were identified through factor analysis. Also, we examined teachers' empirical view of scaffolding functions in open inquiry through in-depth interviews with four teachers. The results of exploratory factor analysis revealed that there were five scaffolding components of open inquiry: motivation, planning, strategy, environment and participation. The results of focus group interviews showed that students experienced difficulties in planning, strategy, environment and participation components, except for motivation component. In particular, students asked for support to strengthen the participation component, which means recognizing their role, active participation and collaboration with peers. Meanwhile, the results of in-depth interviews with teachers showed that teachers' empirical views of scaffolding function in open inquiry were categorized as cognitive (conceptual, metacognitive), emotional (motivational, arbitrative) and strategic. Interviewed teachers preferred the strategic scaffolding and cognitive scaffolding to the emotional scaffolding. Based on the results, we also discussed the implications for performing open inquiry effectively.
