This paper investigates a dynamic mechanism underlying the process of knowledge creation and evolution with a focus on the SECI model(standing for Socialization, Externalization, Combination, Internalization) as proposed by Nonaka and Takeuchi(1991) and broadly accepted especially among the practitioners in knowledge management field. The SECI model provides with intuitive logic and clear delineation of knowledge types between the tacit and the explicit, and embodies an interaction dynamic. However explanations of the propelling forces for the knowledge transfer over the four quadrants of the model is yet to be made. And the transmission mechanisms are not prescribed though the model mentions knowledge is created and evolved in a spiral process. This paper, therefore attempts first to extend and elaborate it into a dynamic SECI model by identifying those propelling factors and their relationships(linkages) based on the systems thinking.

This paper describes a new data-handing, based on a Spatial Human Interface as human indicator, to the Spatial-Knowledge-Tags (SKT) in the spatial memory the Spatial Human Interface (SHI) is a new system that enables us to facilitate human activity in a working environment. The SHI stores human activity data as knowledge and activity history of human into the Spatial Memory in a working environment as three-dimensional space where one acts, and loads them with the Spatial-Knowledge-Tags(SKT) by supporting the enhancement of human activity. To realize this, the purpose of SHI is to construct new relationship among human and distributed networks computers and sensors that is based on intuitive and simultaneous interactions. In this paper, the specified functions of SKT and the realization method of SKT are explained. The utility of SKT is demonstrated in designing a robot motion control.

Research in the decision sciences has continued to develop a variety of mathematical models as well as software tools supporting corporate decision-making. Yet. in spite of their potential usefulness, the models are little used in real-world decision making since the model solution processes are too complex for ordinary users to get accustomed. This paper proposes an intelligent and flexible model-solver integration framework that enables the user to solve decision problems using multiple models and solvers without having precise knowledge of the model-solution processes. Specifically, for intuitive model-solution, the framework enables a decision support system to suggest the compatible solvers of a model autonomously without direct user intervention and to solve the model by matching the model and solver parameters intelligently without any serious conflicts. Thus, the framework would improve the productivity of institutional model solving tasks by relieving the user from the burden of leaning model and solver semantics requiring considerable time and efforts.

The purpose of this thesis is to search the situation of an outbreak of the fallacy and methods of its treatment. We regard intuition as origins of genuine knowledge, but it sometimes raises the fallacy by intrinsic characters of itself. It makes an examination of the fallacy of the sense of sight like an optical illusion to instance that of sense. The sense of sight is an important factor in an intuitive cognition. However, its activity without thinking raises the fallacy of intuition in the process to observe and judge the things. I point out the fallacy of intuition which originates from terms and concepts in mathematical problems. The concept of mean velocity is representative. In this case, students make a mistake which means velocity can be solved by dividing the sum of v$_1$ and v$_2$ into two. The methods which overcome the fallacy of intuition are balance of intuition and logic, overcome of functional fixedness, the development of intuitive models and the development of metacognitive ability.

The purpose of this study was to describe decision making model of 180 public health nurses in Korea and their knowledge structure for decision making. The differences of decision making models by nurse's knowledge structure were also tested. Research concepts were measured using the instrument based on systemic and interpretive decision making approaches that were developed by Lauri & Salantera (1995). The results were as follows. 1. The public health nurses turned to, most commonly, a mixed practical-theoretical knowledge structure (45.9%), followed by practical knowledge (32%) and theoretical knowledge (22.1%). 2. The six different decision making models were identified. These were named for decision making theories and nursing process. These were client-oriented decision making, rule-oriented systemic decision making, wholistic and intuitive decision making, decision making depending on subjective view and experience, systemic decision making for defining problems. 3. The public nurses who had practical and practical-theoretical knowledge structure and community health practitioner (CHP) retold that decision making depends on subjective view and experience. Also the public health nurses who had 5~19 years clinical experience represented hypothetico-deductive decision making for defining problems.

There has been considerable research recently on uncertainty handling in the fields of artificial intelligence and knowledge-based system. Various numerical and non-numerical methods have been proposed for representing and propagating uncertainty in knowledge-based system. The Bayesian method, the Dempster-Shafer's Evidence Theory, the Certainty Factor model and the Fuzzy Set Theory are most frequently appeared in the knowledge-based system. Each of these four methods views uncertainty from a different perspective and propagates it differently. There is no single method which can handle uncertainty properly in all kinds of knowledge-based systems' domain. Therefore a knowledge-based system will work more effectively when the uncertainty handling method in the system fits to the system's environment. This paper proposed a framework for selecting proper uncertainty handling methods in knowledge-based system with respect to characteristics of problem domain and cognitive styles of experts. A schema with strategic/operational and unstructured/structured classification is employed to differenciate domain. And a schema with systematic/intuitive and preceptive/receptive classification is employed to differenciate experts' cognitive style. The characteristics of uncertainty handling methods are compared with characteristics of problem domains and cognitive styles respectively. Then a proper uncertainty handling method is proposed for each category.

본 논문에서는 가상 상황속의 사건들에 역사적 맥락을 부여하기 위한 통합적 직관적 정보표현구조로서 시공간 그래프(Spatio-Temporal Graph)를 설계하고 구현하였다. 일반적으로 사건은 공간뿐 아니라 시간을 점유함으로써 역사적 사실이 된다. 따라서 가상 상황을 시뮬레이션하기 위해서는 공간적 측면을 표현하기 위한 삼차원 정보구조에 시간적 측면을 더한 다차원적인 맥락에 사건들을 위치시키는 일이 핵심적 기초가 된다. 이러한 다차원적 맥락은 온톨로지 뷰, 인스턴스 뷰, 시공간 뷰, 실제 뷰 등과 같은 여러 수준에서의 통합적 직관적 지식표현수단들을 통해 구현된다. 이와 같이 구현된 시공간 그래프에 기반한 시뮬레이션 시스템에 예제 시나리오를 적용하여 실용성을 검증한다. 본 기술은 지능형 교육시스템이나 차세대 시뮬레이션 게임 등에 필수적인 다양한 상황들을 제공하는 시뮬레이션 시스템의 중심요소가 된다.

이 연구는 초등 과학 영재가 보이는 추론 사례를 분석하여 SSI 추론 유형별 근거 활용의 특징과 의사결정의 어려움을 이해하는 데 목적이 있다. 이를 위하여 코로나19 관련 쓰레기 문제에 대한 SSI 수업에 참여한 초등 과학 영재 학생 17명의 발화 내용과 학습지를 비형식적 추론의 유형 분석틀로 분석하였으며, 추론의 근거에 따라 이성적 유형, 감정적 유형, 직관적 유형의 3가지로 구분하였다. 분석 결과, 학생들은 SSI 추론의 근거 활용별로 다음의 특징을 보였다. 첫째, 이성적 유형에서 학생들은 과학적 지식과 수치·통계를 객관적 근거로 중요하게 여기고 기록하였다. 반면 객관적 근거를 기록하지 않은 학생들은 이후의 의사결정에 소극적이었다. 둘째, 감정적 유형에서 학생들이 어느 관점에 공감하여 추론하느냐에 따라 제시한 해결책도 달랐다. 이는 학생들이 공감한 대상 외의 SSI에 관한 다양한 입장을 고려하지 못하는 어려움으로도 이어졌다. 셋째, 직관적 유형에서 학생들은 다른 모둠원이 제시한 의견에 반대하면서도 그 이유를 정확한 용어로 설명하지 않았다. 이는 학생들이 문제 해결을 하지 않거나 근거를 비판적으로 검토하지 않는 어려움으로도 이어졌다. 넷째, 두 가지 유형이 결합된 사례도 나타났다. 직관적 유형은 이성적, 감정적 유형에 앞서 나타났다. 직관적 유형은 감정적 유형과 결합되었을 때 개인의 경험과 공감을 바탕으로 감정 이입을 심화시켰으며, 이성적 유형과 결합되었을 때에는 즉각적인 반응으로 그쳤다. 본 연구에서는 이러한 논의를 통해 SSI 수업에서의 교수 지식 연구가 나아가야 할 방향을 비형식적 추론 유형별 근거 활용의 특징과 의사결정의 어려움 관점에서 제언하였다.

This study was focused on analyzing students' informal reasoning patterns and their considerations in decision-making on socioscientific issues. This study involved 20 undergraduate students (10 biology majors and 10 non-biology majors) and showed how the two groups responded on socioscientific issues. Semi-structured interviews were conducted twice respectively based on six scenarios of gene therapy and human cloning. The result showed 93% of the total number of participants' decisions were made by rationalistic reasoning, whereas emotional reasoning was 49%, and intuitive reasoning was 27%. Students usually used two or three informal reasoning patterns together. Most of the students took more consideration on social factors. Some perceived ethical and moral implications of the issues, but they did not consider them seriously. They made their decisions depending on their own values, etc. 65% of the participants got their information on socioscientific issues from the mass media. Biology majors hardly used intuitive reasoning compared to non-biology majors. The Biology major group took into deep considerations on socioscientific issues while the non-biology major group seemed to interpret the given scenarios simply. This implied that the content knowledge was a significant factor of their decision-making. Therefore, it is necessary to develop proper science courses for non-major students to improve their decision-making on socioscientific issues. So, when we develop educational materials or programs, we should consider students' reasoning patterns, their considerations in decision-making, and their content knowledge. And because the mass media has the potential to play a key role for an effective education, we need to make a plan to make a practical application.
