Purpose: Knowledge, clinical reasoning, and self-confidence are the basis for undergraduate education, and determine students' level of competence. The purpose of this study was to assess the effects of the addition of a one-time simulation experience to the didactic curriculum on nursing students' knowledge acquisition, clinical reasoning skill, and self-confidence. Methods: Using a quasi-experimental crossover design consisted of intervention and wait-list control groups. Participants were non-randomly assigned to the first intervention group (Group A, n=48) or the wait-list control group (Group B, n=46). Knowledge level was assessed through a multiple choice written test, and clinical reasoning skill was measured using a nursing process model-based rubric. Self-confidence was measured using a self-reported questionnaire. Results: Results indicated that students in the simulation group scored significantly higher on clinical reasoning skill and related knowledge than those in the didactic lecture group; no difference was found for self-confidence. Conclusion: Findings suggest that undergraduate nursing education requires a simulation-based curriculum for clinical reasoning development and knowledge acquisition.

Most real world design evaluation and risk-based decision support combine quantitative and qualitative (linguistic) variables. Decision making based on conventional mathematics that combines qualitative and quantitative concepts always exhibit difficulty in modelling actual problems. The successful selection process for choosing a design/procurement proposal is based on a high degree of technical integrity, safety levels and low costs in construction, corrective measures, maintenance, operation, inspection and preventive measures. In this paper, a design decision support framework using a composite structure methodology grounded in approximate reasoning approach and evidential reasoning method is suggested for design evaluation of machinery space of a ship engine room at the initial stages. An illustrative example is used to demonstrate the application of the proposed framework.

As the role of information collection becomes increasingly important in the enormous data environment, there is growing demand for more intelligent information technologies for managing complex data. On the other hand, it is difficult to find a solution because of the data complexity and big scaled amount. Accordingly, there is a need for a special intelligent knowledge base frame that can be operated by itself flexibly. In this paper, by adopting switching function for signal transmission in the synapse of the human brain, I/E selective activation based knowledge reconfiguring mechanism is proposed for building more intelligent information management system. In particular, knowledge network design, a special knowledge node structure, Type definition, I/E gauge definition and I/E matching scheme are provided. Using these concepts, the proposed system makes the functions of activation by I/E Gauge, selection and reconfiguration. In a more efficient manner, the routing and reasoning process was performed based on the knowledge reconfiguration network. In the experiments, the process of selection by I/E matching, knowledge reconfiguration and routing & reasoning results are described.

In recent years, there have been a number of applications of fuzzy logic in fuzzy reasoning system. The main objective of these applications is to approximate a decision making using the fuzzy reasoning system. This paper designs a fuzzy reasoning model for the decision making of registration fee at a private school, implements it applying for linguistic variables and fuzzy rules, and evaluates the practical availability of the model. The system accepts fuzzy rules, the type of membership functions, the domain of fuzzy sets and hedge, and fuzzifies the linguistic variables to generates fuzzy sets. The fuzzy sets generated are combined to constructs a solution fuzzy set. Finally, the system defuzzifies the solution fuzzy set to calculate a scalar value which is used for decision making.

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.

빠른 웹 정보의 변화에 잘 대응하기 위해서는, 사실과 지식이 실제로 유효한 시간과 장소들도 함께 표현하고 그들 간의 관계도 추론할 수 있도록 웹 기술의 확장이 필요하다. 본 논문에서는 그동안 소규모 지식 베이스를 이용한 실험실 수준의 정성 시간 추론 연구들에서 벗어나, 웹 스케일의 대규모 지식 베이스를 추론할 수 있는 병렬 정성 시간 추론기인 MRQUTER의 설계와 구현을 소개한다. Hadoop 클러스터 시스템과 MapReduce 병렬 프로그래밍 프레임워크를 이용해 개발된 MRQUTER에서는 정성 시간 추론 과정을 인코딩 및 디코딩 작업, 역 관계 및 동일 관계 추론 작업, 이행 관계 추론 작업, 관계 정제 작업 등 몇 개의 MapReduce 작업으로 나누고, 맵 함수와 리듀스 함수로 구현되는 각각의 단위 추론 작업을 효율화하기 위한 최적화 기술들을 적용하였다. 대규모 벤치마킹 시간 지식 베이스를 이용한 실험을 통해, MRQUTER의 높은 추론 성능과 확장성을 확인하였다.

For system maintenance optimization, it is necessary to establish a state information system by CBM+ including CBM and RCM, and sensor selection for CBM+ application requires system process for function model analysis at the early design stage. The study investigated the contents of CBM and CBM+, analyzed the function analysis tasks and procedures of the system, and thus presented a D-FMEA based sensor selection inference methodology at the early stage of design for CBM+ application, and established it as a D-FMEA based sensor selection inference process. The D-FMEA-based sensor inference methodology and procedure in the early design stage were presented for diesel engine sub assembly.

Many intelligent agent systems are known to incorporate BDI architecture for cognitive reasoning. Since this architecture contains all the knowledge of world model and reasoning rule, it is very complex and difficult to handle. This paper describes a methodology to design and implement BDI architecture, BDIAXml based on XML for multi-agent systems. This XML-based BDI architecture is smaller than any other BDI architecture because it separates knowledge for reasoning from domain knowledge and enables knowledge sharing using XML technology. Knowledge for BDI mental state and reasoning is composed of specific XML files and these XML files are stored into a specific knowledge server. Most systems using BDIAxml architecture can access knowledge from this server. We apply this BDIAXml system to domain of Hospital Information System and show that this architecture performs more efficiently than other BDI architecture system in terms of knowledge sharing, system size, and ease of use.

The purpose of this study was to examine the effect of the traditional fairy tales based program on the improvement of preschoolers level of distributive justice reasoning. The program was developed on the six Korean fairy tales which deal with the sharing problem among the friends and the families. The subjects were seventy-six, 4- and 5-year-old children selected from two kindergartens in Seoul and Ichon. Solomon 4-group experimental design was used. Each children were assigned for 2 experimental groups and for 2 control groups. Before the intervention, the subjects in experimental group 1 and control group 1 were interviewed individually with story dilemmas for their distributive justice reasoning. For eight-week period, the program based on six Korean traditional fairy tales were used as an intervention. After the intervention, all the subjects were interviewed individually with another story dilemmas. The data were analyzed in SPSS Win 10.0 program, by frequency, percentile, mean, standard deviation, paired t-test and independent t-test. As a result, the children in experimental groups had higher level of distributive justice reasoning than those in control groups. That is, program based on the traditional fairy tales gave positive effect on preschoolers distributive justice reasoning.
