The purpose of this study is to develop lesson plans. teaching guide, and teaching materials applying practical reasoning teaching model in the area of ’human development and family relationship’in middle school home economics. The practical reasoning teaching model consists of five factors: Desired results, Awareness of context, Alternative approaches, Consequences of action, and Action. This study based on practical reasoning has following process: Curriculum development. Developing lesson pan, teaching material, an teaching guide, Experimental teaching and evaluation. Feedback, Production of CD-Rom. Teaching guide includes lesson plan, workbook multimedia materials and teaching resources. Especially teaching guide in CD-Rom can be used effectively in the actual teaching. In the classroom, this teaching model accomplished active and interesting participation of teachers and students. It is proposed that practical reasoning teaching model should be applied to other areas of home economics. In addition various teaching materials based on practical reasoning need to developed.

This paper proposes inter-level causal reasoning to implement synergistic approach. We decompose KOSPI prediction model into economy and industry level. Two kinds of intra-level QCOM are combined in inter-level QCOM via Inter-level relations. Downward reasoning is achieved by propagating the disturbance in the higher level to lower level while upward reasoning is to analyze the reverse cases.

In this work, a fuzzy petri net model for modeling a general form of fuzzy production system which consists of chaining fuzzy production rules and so requires multistage reasoning process is presented. For the obtained fuzzy petri net model, the net will be transformed into some matrices, and also be systematically led to an algebraic form of a state equation. Since it is fond that the approximate reasoning process in fuzzy systems corresponds to the dynamic behavior of the fuzzy petri net, it is further shown that the multistage reasoning process can be carried out by executing the state equation.

This study proposes hybrid case-based reasoning and genetic algorithms model for customer classification. In this study, vertical and horizontal dimensions of the research data are reduced through integrated feature and instance selection process using genetic algorithms. We applied the proposed model to customer classification model which utilizes customers' demographic characteristics as inputs to predict their buying behavior for the specific product. Experimental results show that the proposed model may improve the classification accuracy and outperform various optimization models of typical CBR system.

We focus on open-domain question-answering tasks that involve a chain-of-reasoning, which are primarily implemented using large language models. With an emphasis on cost-effectiveness, we designed EffiChainQA, an architecture centered on the use of small language models. We employed a retrieval-based language model to address the limitations of large language models, such as the hallucination issue and the lack of updated knowledge. To enhance reasoning capabilities, we introduced a question decomposer that leverages a generative language model and serves as a key component in the chain-of-reasoning process. To generate training data for our question decomposer, we leveraged ChatGPT, which is known for its data augmentation ability. Comprehensive experiments were conducted using the HotpotQA dataset. Our method outperformed several established approaches, including the Chain-of-Thoughts approach, which is based on large language models. Moreover, our results are on par with those of state-of-the-art Retrieve-then-Read methods that utilize large language models.

기존의 문제해결 유추(Problem Solving Analogies)의 사고과정은 표상, 접근, 사상, 적용, 학습의 5단계로 요약된다. 본 연구의 목적은 일반적인 문제해결 유추의 사고과정을 토대로 수학교육이라는 특수성이 반영된 '유추 사고과정 모델'을 개발하여 궁극적으로 학생들이 더 많이 유추를 사용할 수 있도록 도움을 주는데 있다. 모델의 개발과정은 먼저 Euler가 유추를 사용해 수학적 발견을 시도한 역사적인 사례를 분석하여 가설적 유추 사고과정 모델(초안)을 설계한 후, 연구자가 고안한 유추과제 즉, 피타고라스 정리의 증명을 유추적으로 연결시켜 코사인법칙을 증명하는 과제를 수학영재들로 하여금 해결하도록 하고, 그 해결과정에서 나타나는 사고과정의 특성을 반영하여 모델을 2차에 걸쳐 수정 보완하였으며, 교육적인 시사점을 도출하였다.

This paper presents the construction of an active suspension system of a one-wheel car model by using fuzzy reasoning. The car model is approximately described by a nonlinear two degrees freedom system subject to excitation from a road profile, and the active control force is constructed by actuating a pneumatic actuator, and the degradation of the performance due to the delay of the pneumatic actuator is improved by inserting a compensator. The fuzzy control is obtained by single input rule modules fuzzy reasoning, and the excitation from the road profile is estimated by using a disturbance observer. The experimental result shows that the proposed active suspension system much improves the performance in the vibration suppression of the car model.

The use of holographic standardized patient (HSP) with mixed reality can provide students with the opportunity to enhance clinical reasoning skills. This is still relatively new, so there is a lack of guidelines for educators. Thus, we aimed to develop the instructional model of HSP-based education, for enhancing clinical reasoning skills in undergraduate healthcare education, which could systematically guide educators in designing and implementing HSP-based teaching and learning activities appropriately. Using a design and development research, a theoretically constructed initial mode in this study was iteratively improved and underwent validation through expert review and model usability test. Features of the model were discussed, along with theoretical and practical implications and suggestions for further research.

Fuzzy reasoning has been applied to analysis of traffic problems on urban arterial road. As the analysis on factors of route choice has been already carried out, its result can be used for construction of the model. Route choice rate estimation by fuzzy reasoning was discussed from its structure and accuracy. The major objective of the study is to introduce some kinds of methods with fuzzy reasoning and to make their feature obvious. First, the production system model is introduced with consideration of reality to actual travel behavior. Second, overlapping areas of fuzzy language function are investigated. Finally, process of fuzzy reasoning was also considered. Five kinds of Fuzzy reasoning are compared to investigate in relation between shapes of membership function and estimation validity.

지구과학 탐구 대상은 다른 학문의 탐구 대상과 달리 거대한 시 공간적 규모, 접근 불가능성, 통제 불가능성, 복잡성 등을 지니고 있다. 그렇기 때문에 지구과학의 탐구 대상을 실험실 내에서 실제 조작을 통해 탐구하는 것은 매우 어렵거나 심지어 불가능하다. 따라서 지구과학에서는 실제 조작을 하지 않고도 탐구를 할 수 있는 대안이 필요하다. 실제 조작을 하지 않고 탐구를 수행하는 대표적인 탐구인 사고실험으로부터 추론의 역할을 재조명하고 추론을 사용한기존의 탐구 수업 모형들의 특징을 조사하였다. 각 탐구 모형들을 지구과학에 적용하는데 있어서의 시사점을 살펴보고 이들을 바탕으로 지구과학적 현상의 탐구에 적합한 추론 중심 탐구수업 모형을 제안한다.
