웹 기반 교수-학습체계를 설계 시에 학습자의 효율적인 상호작용을 통해서 학습효과를 높이기 위해서는 많은 것들이 고려되어야 한다. 무엇보다도 웹 환경에서 학습자에게 효율성과 관심을 유도하기 위해서 웹 기반 시뮬레이션이 권장된다. 이러닝에서 잘 설계된 시뮬레이션 기반 콘텐츠는 학습자에게 지속적인 관심을 제공하기 때문에 효율적인 학습 설계가 필요하다. 현재까지 많은 이러닝 시스템에서는 각기 다른 기법으로 웹 기반 시뮬레이션을 제공하고 있으나 학습자의 학습 스타일과 성취 수준을 고려한 콘텐츠의 재구성이 요구되고 있다. 본 논문에서는 XML 웹 서비스를 통해서 이러닝 시스템간에 시뮬레이션 객체를 공유하는 시스템을 제안하였다. 실험결과 제안 시스템이 기존 시스템보다 자기주도적 학습 활동과 상호 작용에서 효율적임을 보여준다.

This research paper describes a complex and vague settings in which organization makes a decision and explains a role of decision maker's learning process. The original paper, written by Cohen, March, Olsen in 1972, said that all members of organization depended on the technology taken through trials and errors, which is the 'learning' process literally. But they intended to exclude the learning process in their simulation model because their PORTRAN model couldn't replicate the learning concept. As a result, they couldn't explain how all agents of garbage can simulation model resolve the problem dynamically. To overcome this original paper's limitations, we try to rebuild a learning process simulation model using by system dynamics approach that can capture the linkage between organization leanings and agents-based decision-makings. Our learning simulation results reveal two points. First, decision maker's leanings process improves the efficiency of decision making in complex situation. Second, group learning shows a superior efficiency to an individual learning because group members share organizational memory and energy.

The robot soccer simulation game is a dynamic multi-agent environment. In this paper we suggest a new reinforcement learning approach to each agent´s dynamic positioning in such dynamic environment. Reinforcement learning is the machine learning in which an agent learns from indirect, delayed reward an optimal policy to choose sequences of actions that produce the greatest cumulative reward. Therefore the reinforcement learning is different from supervised learning in the sense that there is no presentation of input-output pairs as training examples. Furthermore, model-free reinforcement learning algorithms like Q-learning do not require defining or learning any models of the surrounding environment. Nevertheless ...

본 연구의 목적은 일개 대학 간호과 3학년 학생 145명을 대상으로 학습유형별 시뮬레이션 교육 전 후 자기효능감, 문제해결능력, 임상수행능력 차이를 파악하여 학습유형별 시뮬레이션 교육을 제공하기 위한 기초자료를 마련하고자 실시하였다. 본 연구는 시뮬레이션교육 후 학습유형별로 효과를 검증하기 위한 단일군 전후설계 실험연구이다. 본 연구 결과 간호학생의 학습유형은 적응자가 가장 많았으며, 시뮬레이션 교육 후 문제해결능력(F=5.015, p=.02)과 임상수행능력(F=3.288, p=.02)은 유의한 차이를 나타냈으며, 문제해결능력은 융합자와 분사자가 적응자보다, 임상수행능력은 융합자가 적응자보다 유의하게 높게 나타나 학습유형별 시뮬레이션 교육의 효과에 차이가 있음을 확인하였다. 그러나 자기효능감은 통계적으로 유의한 차이를 나타나지 않았다. 이상의 연구결과를 바탕으로 학습유형별로 시뮬레이션교육을 제공할 수 있을 것으로 기대된다.

본 연구는 웹 3D와 가상현실 기반 시뮬레이션 학습의 사용성 평가와 학업성취도를 비교분석하고, 각 학습방법 간의 학습효과 차이를 통해 가상현실 콘텐츠의 차별화된 특징을 확인하는 것이 목적이다. 이를 위해 생명과학전공 대학생 75명을 모집단(웹 3D=37, VR=38)으로, DNA 분석의 과학실험을 위해 두 가지 학습방법으로 개발된 Labster사의 CSI Forensics Lab 시뮬레이션 콘텐츠를 실험처치물로 학습자의 사용성 평가와 학업성취도를 비교분석하였다. 연구결과, 태스크 수행, 탐색과 내비게이션의 사용성 평가에서는 웹 3D 시뮬레이션 학습이 유의미한 차이로 긍정적이었으나 만족도의 사용성 평가에서는 가상현실 시뮬레이션 학습이 유의미한 차이로 보다 긍정적이었다. 학업성취도에서는 웹 3D 시뮬레이션 학습 평균이 다소 높았으나 두 학습 간 유의미한 차이를 확인하지 못했다.

Finite element simulation is a widely applied method for practical purpose in various metal forming process. However, in the simulation of elasto-plastic behavior of porous material or in crystal plasticity coupled multi-scale simulation, it requires much calculation time, which is a limitation in its application in practical situations. A machine learning model that directly outputs the constitutive equation without iterative calculations would greatly reduce the calculation time of the simulation. In this study, we examined the possibility of artificial intelligence based constitutive equation with the input of existing state variables and current velocity filed. To introduce the methodology, we described the process of obtaining the training data, machine learning process and the coupling of machine learning model with commercial software DEFROM^TM, as a preliminary study, via rigid plastic finite element simulation.

Purpose: The purpose of this study was to examine the effects of simulation-based learning on the knowledge about and performance confidence in the nursing care of children with asthma. Methods: A one-group pre- and post- study design was used. A total of 70 nursing students participated in the study. In groups of five, the participants experienced simulation-based learning during their child health nursing practicum. The given scenario was about nursing care for children with asthma. The simulation learning was provided for 3 hours, and included a group discussion before the simulation and a debriefing. Results: After the simulation, knowledge about and performance confidence in the nursing care of children with asthma significantly increased. The nursing students reported a high level of satisfaction with the simulation-based learning. There was a significant positive correlation between knowledge and performance confidence. Conclusion: Simulation-based learning was effective for nursing students in the nursing care of children with asthma. Our results suggest utilizing this new way of learning to strengthen the clinical experience of child health nursing in nursing students.

Purpose: With the decrease in available clinical sites, a decrease in adequately prepared clinical faculty, and demand to prepare health care students to begin work, we need alternative methods to teach clinical skills for health care professionals. The use of simulation as an educational process that can replicate clinical practices is becoming popular in nursing. Therefore, this study was conducted to review directions of simulation-based learning in nursing education. Methods: A systematic review of quantitative studies was undertaken using Medline, KERIS, and KISS. The primary search terms were simulation and nursing. Reference lists from relevant papers and the websites of relevant nursing organizations were also searched. Nine studies met inclusion criteria and were analyzed in detail. Results: All studies reported simulation as a valid teaching/learning strategy. Six of the studies (66.7%) showed that simulation technology was a practical and successful model to use in teaching a variety of clinical skills for nursing students and nurses. Conclusion: Simulation may have some advantages over other teaching methods, depending on the scenario, context, topic, and method. Further study is needed to determine the effect of team size on learning and to develop a universal method of outcome measurement.
