오늘날 지능형 교수 시스템은 과거와는 달리 전문영역 지식, 학습자 지식과 융통적인 개별 학습과 개인교수를 지원하기 위한 교수 전략에 대한 지식이 사용되고 있다. 학습자들이 배웠던 내용이 무엇인지를 설명하고 가르칠 도메인 지식을 전문영역 지식으로 표현한다. 교수법 모듈은 학습을 제어하거나 가르치기 위한 모든 결정을 한다. 학생 모형은 학습자의 지식을 기술하고 학습자 개개인에 대한 특정한 정보를 저장한다. 본 논문에서는 지능형 교수 시스템의 구성 요소인 학습자 모형의 지식을 기존의 인공지능에서의 지식 표현 기법인 생성 시스템의 절차 지식을 온톨로지를 사용하여 설계하였다.

이 연구에서는 통제된 색인어를 이용하여 파악한 지식 구조와 통제되지 않은 키워드를 이용한 지식 구조를 비교하여 두 구조가 어떤 차이점을 보이는지를 살펴보았다. 또한 색인효과가 어떻게 나타나는지, 비통제어를 사용한 경우가 실제적으로 더 상세한 하위 영역을 표현하는지를 확인하고자 하였다. 실험 결과 통제된 색인어인 주제명표목을 사용한 영역지도와 비통제 색인어인 키워드를 사용한 영역지도 둘 다 인공지능 분야의 주요 분야들을 비슷하게 나타냈지만, 주제명표목을 사용한 경우에 색인효과가 일부 나타났다. 그리고 대체적으로 주제명표목에 기반한 영역지도보다는 키워드에 기반한 영역지도가 더 상세하게 나타났다.

While this paper will be of interest to Convergence of Knowledge and Border Thinking, one of my main concerns has been to open the world of mind. Because the convergence of knowledge and border thinking are closely related to the problems of mind. It should be clear from this procedure that the scope of this study is limited. It is not intended to be a definitive account of all problems of mind, bur rather a clear and thorough account of that segment of mind that pertains to an analysis of convergence of knowledge and border thinking. This claim, with their supporting arguments, will be discussed as follow; 1. What our knowledge has been for? 2. Knowledge and convergence of knowledge 3. How is the convergence of knowledge made up? 1) meeting at border 2) mind as a border 3) converging at mind.

The smart factory is an important axis of the 4th industrial revolution. Smart factory is a system that induces the maximum efficiency and effectiveness of production using the IoT and intelligent sensing systems. The product lifecycle management technique is a method that can actively reflect the consumer's requirements in the smart factory and manage the entire process from the consumer to the post management. There have been many studies on product lifecycle management, but studies on how to organize product lifecycle management knowledge domains in preparation for the era of the 4th industrial revolution were insufficient. This study analyzed the opinions of a group of experts preparing for the 4th industrial revolution in terms of product lifecycle management. The impact of the 4th industrial revolution on the detailed knowledge areas of product lifecycle management was investigated. The changes in product lifecycle management were summarized using a qualitative data analysis technique for a group of experts. Based on the opinions of experts, the product lifecycle management, which consists of a total of 30 detailed knowledge areas, was prepared to supplement or prepare for the 4th industrial revolution. This study investigates changes in product lifecycle management in preparation for the 4th industrial revolution in the knowledge domain of the existing defined product life cycle management. In future research, it is necessary to redefine the knowledge domain of product life cycle management suitable for the era of the 4th industrial revolution and investigate the perception of experts. Considering the social culture and technological change factors of the 4th industrial revolution, the scope and scope of product life cycle management can be newly defined.

This study aimed to investigate technological pedagogical and content knowledge(TPACK) model, and to apply this model to preservice education. To perform this study, TPACK survey instrument was distributed to 142 preservice teachers who took technology integration course. The result showed that technology and content knowledge improved significantly, and pedagogical and pedagogical content knowledge did not show meaningful differences among 7 sub-categories. Based on the result of this study, we discussed the improvement of technological and content knowledge, and pedagogical knowledge. Also, we suggested that (preservice) teacher education should consider the combination of technological, pedagogical, and content knowledge in Korea.

The geographical knowledge is composed of academic geographical knowledge, school geographical knowledge, applied geographical knowledge and popular geographical knowledge according to the diverse social need and demand. And the geographical knowledge has developed through the knowledge circulation system, which is connected to knowledge production, delivery, application and to reproduction among these knowledge fields. The discontinuity of knowledge circulation can lead to crisis of geographical whole. Therefore, for sustainable development of geography, it is necessary to firmly build a virtuous circulation system of geographical knowledge which is linked to a knowledge production and accumulation by an academic geography, knowledge delivery by a school geography, knowledge social application by an applied geography, knowledge application in everyday life by a popular geography and knowledge reproduction by an academic geography.

본 논문은 그레이 영상에서의 사람얼굴 영역추출에 관해서 연구하였다. 얼굴영역 추출은 얼굴인식이나 사람과 컴퓨터의 인터페이스, 비디오 감시시스템을 연구하는데 있어서 반드시 거쳐야 하는 전처리 과정이라고 할 수 있다. 이러한 목적을 위해서 본 연구에서는 두 단계의 과정을 통해서 얼굴영역을 추출하였다. 첫 번째 단계는 사랑얼굴에 대한 경험적 지식을 이용하여 후보영역을 획득한 다음에 두 번째 단계에서 후보영역을 웨이블릿 분해 후, 신경망을 이용하여 후보영역 중에서 얼굴영역을 검증한다. 실험결과 제안한 방법은 빠르고 정확하게 얼굴영역을 검출하였다.

본 연구에서는 웹 문서를 분류하기 위해서 분류하고자 하는 영역(category)에 대한 개념 지식을 이용한다. 먼저, 영역별 개념 지식을 기구축된 웹 문서의 집합으로부터 제목과 하이퍼링크에 기반한 앵커 텍스트를 이용하여 개념을 보유한 키워드를 추출한다. 추출된 키워드를 형태소 분석을 통해 색인어로 추출한다. 추출된 색인어에 대해 TFIDF를 확장한 영역 적용 색인 가중치 TFIDFc를 적용하여 영역별 개념 기반 색인어와 색인를 구축한다. 색인은 TFIDF를 영역별로 확장하여 구축한다. 구축된 영역별 개념 기반 색인을 이용하여 새로운 웹 문서에 대해서 어떤 영역에 해당하는 가를 결정하는 자동 분류 알고리즘을 수행한다. 자동 분류 알고리즘에 의해 수행된 문서는 영역별로 정리되며, 또한, 분류된 웹 문서의 색인어는 새로운 개념 기반 키워드로 추출되어 개념 기반 영역 지식을 구축한다.

Knowledge management strategy has become a one of the most important factors creating and maintaining the business opportunities. In this paper, I present a KM-ePAY typology to investigate the role of knowledge sharing strategy in the electronic payment domain. Specifically, I examine the characteristics of four types of electronic payment systems based on the confidence and efficiency that characterize the feature of electronic payment media and identify appropriate knowledge sharing approaches for each component. In conclusion, my findings indicate that knowledge sharing approaches which are align with the characteristics of electronic payment give a way both to increase relationship commitment and to optimize process over electronic payment transactions.
