The purpose in this study was to investigate stages of concern of home economics teachers about the practical reasoning instruction(PRI) innovation configuration. levels of use. using Concerns Based Adoption Model(CBAM) The design of the study was descriptive. The Questionnaires of stages of concern. levels of use. and innovation configuration developed by Hall in 1987 were used. Data from HE teachers were collected through mailing. focus interview. and phone calls. Mean. percents. an frequencies were used to describe stages of concern, level of use. and innovation configuration. The results of the study were as follows: 1. The highest number of HE teacher respondents was stage 1. Information in March and july. 2 In terms of mean of PRI configuration. percentile. the HE teachers had implemented over 63% of the PRI elements and the cooperative learning elements in both March and July. However. of evaluation elements, 33% in March and 47% in July had been conducted. 3. The highest number of HE teacher respondents was level 3. Mechanical level in March. and July.

In this paper, we proposes a man-machine interface design for fault diagnosis system with inter-node search method in a Petri net model. First, complicated fault cases are modeled as the Petri net graph expressions. Next, to find out causes of the faults on which we focus, a Petri net model is analyzed using the backward reasoning of transition-invariance in the Petri net. In this step, the inter-node search method algorithm is applied to the Petri net model for reducing the range of sources in faults. Finally, the proposed method is applied to a fault diagnosis of a refrigeration system to confirm the validity of the proposed method.

In this paper, Fuzzy Self-organizing Neural Networks(FSONN) based on Fuzzy Neural Networks(FNN) is proposed to overcome some problems, such as the conflict between ovefitting and good generation, and low reliability. The proposed FSONN consists of FNN and SONN. Here, FNN is used as the premise part of FSONN and SONN is the consequnt part of FSONN. The FUN plays the preceding role of FSONN. For the fuzzy reasoning and learning method in FNN, Simplified fuzzy reasoning and backpropagation learning rule are utilized. The number of layers and the number of nodes in each layers of SONN that is based on the GMDH method are not predetermined, unlike in the case of the popular multi layer perceptron structure and can be generated. Also the partial descriptions of nodes can use various forms such as linear, modified quadratic, cubic, high-order polynomial and so on. In this paper, the optimal design procedure of the proposed FSONN is shown in each step and performance index related to approximation and generalization capabilities of model is evaluated and also discussed.

2020년 기준 국내 게임 시장은 작년 대비 21.3%가 증가하였으며, 그 중 모바일 게임 시장은 전체 게임 시장의 57.4%를 점유하고 있다. 이는 전년 대비 약 40% 성장한 모습으로 모바일 기기의 접근성과 성능의 향상으로 질 좋은 게임들을 장소에 구애받지 않고 즐길 수 있기 때문이다. 본 논문은 "김 탐정과 이상한 마을"이라는 모바일 게임을 설계하고 구현한다. 김탐정이 이상한 마을의 촌장에게 의뢰를 받아 마을에서 일어나는 사건들을 조사하여 사건들을 해결하는 스토리기반 텍스트추리 모바일게임이다. 게임의 스토리를 바탕으로 도트 프로그램과 포토샵을 이용하여 게임 배경, 캐릭터 디자인을 하였으며, 유니티를 이용하여 구현하였다.

Current CAD systems are good enough to be used as a tool to manipulate three-dimensional shapes. This is a very important capability to be owned by a design tool because a major portion of designers'activities is spent on the shape manipulation in the design detailing process. However, the whole design process involves a lot more than the, shape manipulation. Currently, these remaining tasks, mostly logical reasoning process for the function realization together with structure decomposition in the top-down manner, are processed in the designer's brain. To support the top-down functional design process of a mechanical product, a system integrating the functional, structural and geometrical aspects of a product design in a unified environment is presented. Using this system, a designer can perform function decomposition, structure decomposition, and geometry detailing, and function verification activities in parallel and the whole design process it modeled resultantly. Once the whole design process is modeled, any redesign task can be automatically performed with the verification of the desired functions.

Features are generic shapes with which engineers associate certain attributes and knowledge useful in reasoning about the product. Feature-based modeling systems support additional levels of information beyond those available in geometric modelers. The objective of this study is to develop a PC level feature-based modeling system which explicitly represents dimensions of the part. The feature-based modeler retains all the benefits of traditional B-rep. solid models, and represents the dimensions at a high level of a abstraction so that dimension driven geometry can be achieved.

The activated sludge process is a commonly used method for treating sewage and waste waters. The process is characterized by a lack of measurement instrumentations and control goals that are neither well defined nor well understood. In the present study the concept of fuzzy control is employed for such process in which a design method for fuzzy controller based on a multivariable fuzzy reasoning algorithms is investigated and then simulation results are presented.

This paper has design of ECG pattern classification system using decision of fuzzy IF-THEN rules and neural network. each fuzzy IF-THEN rule in our classification system has antecedent lingustic values and a single consequent class. we use a fuzzy reasoning method based on a single winner rule in the classification phase. this paper in, the MIT/BIH arrhythmia database for the source of input signal is used in order to evaluate the performance of the proposed system. From the simulation results, we can effectively pattern classification by application of learned from neural networks.

Although feature-based design is a promising approach to fully integrating CAD/CAM, current feature-based design approaches seldom provide methodologies to easily define and design features. This paper proposes a new approach to integrating parametric design with feature-based design to overcome those limitations by globally decomposing a design into a set of features and locally defining and positioning each feature by geometric constraints. Each feature is defined as a parametric shape which consists of a feature section, attributes, and a set of constraints. The generalized sketching and sweeping techniques are used to simplify the process of designing features. The proposed approach is knowledge-based and its computational efficiency in geometric reasoning is improved greatly. Parametrically designed features not only have the advantage of allowing users to efficiently perform design changes, but also provide designers with a natural design environment in which they can do their work more naturally and creatively.
