This study explores potential capability of a machine learning approach for monitoring urban morphology based on an evident case study. The case study conveys year 2006 investigations on interpreting urban morphology of Boston Main Streets by applying a machine learning approach. From the lesson of the precedent study, in 2016, another field research and interview was conducted to compare changes in urban situation, data commons culture, and technology innovation during the decade. This paper describes open possibilities to advance urban monitoring for morphological changes. Most of all, a multi-participatory data platform enables managing urban data system in real time. Second, collaboration with machines with artificial intelligence can intervene the framework of the urban management system as well as transform it through new demands of innovative industries. Recently, urban regeneration became a dominant urban planning strategy in Korean, therefore, urban monitoring is on demand. It is timely important to correspond to in-situ problems based on empirical research.

폭발적인 정보의 흐름 속에 놓여 있는 지식정보화 시대에서는 필요한 정보를 선택하고 가공하여 새로운지식의 창조, 전달 및 확대 재생산 할 수 있는 능력이 요구되고 있다. 지식정보화 시대가 필요로 하는 창의적 인재 육성을 위한 새로운 교육 형태와 패러다임으로 e-러닝이 유력한 솔루션으로 부각되고 있다.e-러닝은 교수자 중심의 일방향 교육이 아닌 학습자가 시간과 장소에 구애받지 않고 필요한 학습을 하는 양방향 교육 방식이나, 현재까지는 학습 콘텐츠의 단순 반복 학습에 그치고 있어 기존 교실 수업 방식에 비해 학습효율이 떨어지는 점이 이 분야 발전의 장애요소가 되고 있다. 이에 대한 해결책으로 온라인상에서 학습 과제를 여러 명의 학생들이 상호 의존하여 공동으로 해결함으로써 학습 목표를 달성하는 형태의 협력 학습에 대한 연구가 활발히 진행되고 있다. e-러닝 협력학습에는 단순히 학생들을 그룹화하여 함께 학습하도록 하는 것은 교육 효과면 에서 비효율적일 수 있으며, 학생들의 자발적인 참여와 협력을 유도할 수 있는 교수모형을 적용하여야 하며, 개인의 책임감을 근간으로 한 상호 의존적 과제 해결 활동이 이루어져야 한다. 본 고에서는 협력 e-러닝 학습을 위한 연구사례와 기술 동향들에 대해 살펴본다.

Purpose: This study was conducted to develop and test a structural model of evidence-based practice (EBP) implementation among clinical nurses. The model was based on Melnyk and Fineout-Overholt's Advancing Research and Clinical Practice through Close Collaboration model and Rogers' Diffusion of Innovations theory. Methods: Participants were 410 nurses recruited from ten different tertiary hospitals in Korea. A structured self-report questionnaire was used to assess EBP knowledge/skills, EBP beliefs, EBP attitudes, organizational culture & readiness for EBP, dimensions of a learning organization and organizational innovativeness. Collected data were analyzed using SPSS/WINdows 20.0 and AMOS 20.0 program. Results: The modified research model provided a reasonable fit to the data. Clinical nurses' EBP knowledge/skills, EBP beliefs, and the organizational culture & readiness for EBP had statistically significant positive effects on the implementation of EBP. The impact of EBP attitudes was not significant. The dimensions of the learning organization and organizational innovativeness showed statistically significant negative effects on EBP implementation. These variables explained 32.8% of the variance of EBP implementation among clinical nurses. Conclusion: The findings suggest that not only individual nurses' knowledge/skills of and beliefs about EBP but organizational EBP culture should be strengthened to promote clinical nurses' EBP implementation.

학교현장은 평균 43명의 과밀학급(인천광역시 연수고등학교 2학년)으로, 컴퓨터실에서 교사는 학생들을 관리하기 위해 학생 PC의 전원 끄는 경우가 있다. 교사는 학생의 컴퓨터를 감시하여 수업과 관련 없는 웹(web) 사이트를 방문하는 학생들의 수업 이외의 장난을 막으면서 학생들에게 수업해야 하기 때문이다. 그러나 학생은 이러한 방식에 반발심을 사거나 학생들의 학습 의욕을 떨어트리는 요인으로 작용한다고 본다. 또한 컴퓨터실 수업에서 일반적으로 교사는 "바쁜 교사"이다. 제한된 시간에 학습자 개인의 흥미나 욕구를 반영하여 개별 학습자의 능력 혹은 수준에 맞추어 수업의 내용의 내용과 속도를 다르게 가르치는 개별지도가 불가능하다. 현실이 이렇다 보니 컴퓨터라는 정보화 기기를 활용한 수업이 효율적으로 이루어지지 않고 있다. 본 연구에서는 이러한 문제점을 해결하고자 학습 초기에 개별학습을 하면서 학습 진행에 어려움을 격을 시 학생과 학생사이에 다양한 상호작용을 촉진시키도록 협력학습 체제를 구축하고 학생들의 학습을 모니터링하면서 학생 또는 협력학습 모둠이 문제 해결에 어려움이 처한 경우나 실패한 경우 교사의 개별지도가 가능하게 할 수 있는 실시간 협력학습 체제를 설계하였다.
