When a designer creates a new web-based learning-teaching system, there are so many considerations to help learners' learning effect through effective interaction. First of all, web-based simulation is recommended to provide learners with effective and attractive learning environments in web. Efficient study design should be considered because well designed simulation-based contents provide continuous interest for learner. Until now many e-Learning systems provide web-based simulation using various technique. However, those contents require to be reorganized considering the level of accomplishment, learning styles. In this paper, I proposed a system that the learners can share simulation objects among other e-Learning systems using XML web service. By experimental result, the proposed system shows that is more efficient than the conventional system in the self-leading study activity and interactivity.

웹기반 학습은 학습자의 자율적인 통제하에서 학습이 이루어지는 특성을 갖고 있다. 학습 컨텐츠와 학습자간의 충분한 대화 즉, 상호작용이 제공되지 않는다면 학습자는 일방적인 학습을 수행하게 되므로 학습에 대한 정확한 이해를 판단할 수가 없다. 이런 문제점을 해결하기 위해서 웹기반 학습의 여러 유형의 컨텐츠중에서 가장 상호작용 요소가 강한 시뮬레이션 형태의 컨텐츠를 이용해서 디지털 회로를 직접 학습자가 설계할 수 있도록 웹기반 시뮬레이션 도구를 설계 및 구현하고자 한다. 이로 인해서 학습자와 학습 컨텐츠간의 쌍방향 대화를 할 수 있는 환경을 제공함으로써 복잡한 디지털 회로에 대한 학습자의 학습 결과에 대한 피드백을 줌으로써 학습자의 학습 성취도를 높일 수 있다.

This study was conducted to evaluate the effects of simulation integrated with problem based learning in terms of critical thinking, problem solving, learning motivation according to Myers-Briggs type indicator(MBTI) personality type in advanced nursing course students. This study was a non-equivalent control posttest only design. Students were all enrolled in advanced nursing course which included 1) 6 weeks problem based learning 2) 5 weeks simulation integrated with PBL and debriefing. Total 19 students' data were collected and analyzed on SPSS win 21.0. The results showed students who have out patients working experience were significantly higher learning motivation(${\chi}^2=9.85$, p=.044), no experienced simulation were significantly higher critical thinking(${\chi}^2=4.44$, p=.035) and as temperament of MBTI, NT types were significantly higher on critical thinking(${\chi}^2=8.53$, p=.036). Students show various personality types and it might be impact on attitudes of learning and the results. Thus we need to understand their diversity and consider it to apply teaching methods on nursing education.

This study was conducted in order to develop an education program based on simulation with problem-based learning, to apply it to nursing students, and to examine its effects on the students' learning motivation, learning strategy, and academic achievement. The subjects of this study were 69 seniors majoring in nursing. Education based on simulation with problem-based learning was applied to the students from September to October in 2015, and then a questionnaire survey was conducted on their learning motivation, learning strategy, and academic achievement. According to the results of this study, the education based on simulation with problem-based learning reduced the nursing students' other-directed motivation (external motivation), increased their self-regulation motivation (identified motivation, intrinsic motivation), and improved their use of resource management strategies. In addition, academic achievement (academic performance, and educational satisfaction) was in a positive correlation with identified motivation and learning strategies (cognitive strategy, meta cognitive strategy, and resource management strategy). In conclusion, education based on simulation with problem-based learning was found to be an effective education strategy for enhancing nursing students' autonomous motivation and improving their use of resource management strategies. Thus, it is necessary to promote the application of simulation with problem-based learning in various care situations and to study factors and parameters influencing learning related variables.

This study is to review current state of web-based simulations for science learning about magnets and magnetic field, and evaluate the appropriateness of simulations in terms of contents, strategies and design. We designed a set of criteria for evaluating science simulations and applied it to 14 simulations about magnets and magnetic field. For the evaluation, eight elementary teachers participated and they described specific characteristics of each simulation according to the criteria. Based on the evaluation, we divided the simulations into two groups, excellent vs. normal groups. We analyzed strengths from the simulations in excellent group and weaknesses from the simulations in normal group according to the contents, learning strategies, screen format, and technical features. Implications for ways of improvement in developing web-based science simulations effective to science teaching and learning about magnets and magnetic field were discussed.

Recently, many studies using reinforcement learning-based autoscaling have been performed to make autoscaling policies that are adaptive to changes in the environment and meet specific purposes. However, training the reinforcement learning-based Horizontal Pod Autoscaler(HPA) policy in a real environment requires a lot of money and time. And it is not practical to retrain the reinforcement learning-based HPA policy from scratch every time in a real environment. In this paper, we implement a reinforcement learning-based HPA in Kubernetes, and propose a transfer leanring technique using a queuing model-based simulation to accelerate the training of a reinforcement learning-based HPA policy. Pre-training using simulation enabled training the policy through simulation experience without consuming time and resources in the real environment, and by using the transfer learning technique, the cost was reduced by about 42.6% compared to the case without transfer learning technique.

도시의 인구 밀집도가 증가함에 따라 도시의 단위 면적당 건물 밀집도 역시 증가하고 있으며, 이에 도시 화재는 대규모 화재로 발전할 가능성이 높다. 도시 내 대규모 화재로 인한 인명 및 경제적인 피해를 최소화하기 위해 시뮬레이션 기반의 화재 대응 방안들이 널리 연구되고 있으며, 최근에는 시뮬레이션에서 효과적인 화재 대응 방안을 탐색하기 위해 강화학습 기술을 활용하는 연구들이 소개되고 있다. 그러나, 시뮬레이션의 규모가 커지는 경우, 상태 정보 및 화재 대응을 위한 행위 공간의 크기가 증가함으로 인해 강화학습의 복잡도가 증가하며, 이에 따라 학습 확장성이 저하되는 문제가 발생한다. 본 논문에서는 시뮬레이션 규모 증가 시 강화학습의 학습 확장성을 유지하기 위해, 화재 상황 정보와 재난 대응을 위한 행위 공간을 변환하는 기법을 제안한다. 실험 결과를 통해 기존에 강화학습 모델의 학습이 어려웠던 대규모 도시 재난시뮬레이션에서 본 기법을 적용한 강화학습 모델은 학습 수행이 가능하였으며, 화재 피해가 없는 상황의 적합도를 100%로 하고, 이것 대비 99.2%의 화재 대응 적합도를 달성했다.
