Evolving in artificial agent is an extremely difficult problem, but on the other hand, a challenging task. At present the studies mainly centered on single agent learning problem. In our case, we use simulated soccer to investigate multi-agent cooperative learning. Consider the fundamental differences in learning mechanism, existing reinforcement learning algorithms can be roughly classified into two types-that based on evaluation functions and that of searching policy space directly. Genetic Programming developed from Genetic Algorithms is one of the most well known approaches belonging to the latter. In this paper, we give detailed algorithm description as well as data construction that are necessary for learning single agent strategies at first. In following step moreover, we will extend developed methods into multiple robot domains. game. We investigate and contrast two different methods-simple team learning and sub-group loaming and conclude the paper with some experimental results.

Medical education research subjects are incredibly diverse and have changed over time. This work in particular aims to compare and analyze research trends in medical education through the words used in the titles of these research papers. Academic Medicine (the journal of the Association of American Medical Colleges), Medical Teacher (the journal of the Association of Medical Education in Europe), the Korean Journal of Medical Education (KJME), and Korean Medical Education Review (KMER) were selected and analyzed for the purposes of this research. From 2009 to 2018, Academic Medicine and Medical Teacher published approximately 10 to 20 times more papers than the KJME and KMER. Frequently used words in these titles include "medical," "student," "education," and "learning." The words "clinical" and "learning" were used relatively often (7.80% to 13.66%) in Korean journals and Medical Teacher, but Academic Medicine used these phrases relatively less often (6.47% and 4.41%, respectively). Concern with such various topics as problem-based learning, team-based learning, program evaluations, burnout, e-learning, and digital indicates that Medical Teacher seems to primarily deal with teaching and learning methodologies, and Academic Medicine handles all aspects of medical education. The KJME and KMER did not cover all subjects, as they publish smaller papers. However, it is anticipated that research on new subjects, such as artificial intelligence in medical education, will occur in the near future.

This paper aims to show the learning process and the educational effects of Divide-and-Combine principles and State Models, which are included in the Butterfly Model for creative problem solving. In our State Models, there are Time State Model, Space State Model, and Whole-Parts State Model. We have taught middle school students (for 18 hours), high school students (for 24 hours), and undergraduate students (for 1 semester) about our proposed Models when they solved contradiction problems. Also, we have made the students learn our contradiction resolution algorithms by themselves based on team-based discussion. By learning and by using our Models, the students had the higher level of expertise in contradiction problems and had the growth mindset that made them have confidence in themselves and kept them challenging themselves about problems. Also, learning and solving with our Models improved the students' growth mindset as well as their problem-solving ability.

본 논문에서는 적외선 이미지에서 딥러닝 물체 탐지를 사용하여 유도무기의 표적 탐지 정확도 향상 방법을 연구한다. 적외선 이미지의 특성은 시간, 온도 등의 요인에 의해 영향을 받기 때문에 모델을 학습할 때 다양한 환경에서 표적 객체의 특징을 일관되게 표현하는 것이 중요하다. 이러한 문제를 해결하는 간단한 방법은 적절한 전처리 기술을 통해 적외선 이미지 내 표적 객체의 특징을 강조하고 노이즈를 줄이는 것이다. 그러나, 기존 연구에서는 적외선 영상 기반 딥러닝 모델 학습에서 전처리기법에 관한 충분한 논의가 이루어지지 못했다. 이에, 본 논문에서는 표적 객체 검출을 위한 적외선 이미지 기반 훈련에 대한 이미지 전처리 기술의 영향을 조사하는 것을 목표로 한다. 이를 위해 영상과 이미지의 전역(global) 또는 지역(local) 정보를 활용한 적외선 영상에 대한 전처리인 Min-max normalization, Z-score normalization, Histogram equalization, CLAHE (Contrast Limited Adaptive Histogram Equalization)에 대한 결과를 분석한다. 또한, 각 전처리 기법으로 변환된 이미지들이 객체 검출기 훈련에 미치는 영향을 확인하기 위해 다양한 전처리 방법으로 처리된 이미지에 대해 YOLOX 표적 검출기를 학습하고, 이에 대한 분석을 진행한다. 실험과 분석을 통해 전처리 기법들이 객체 검출기 정확도에 영향을 미친다는 사실을 알게 되었다. 특히, 전처리 기법 중에서도 CLAHE 기법을 사용해 실험을 진행한 결과가 81.9%의 mAP (mean average precision)을 기록하며 가장 높은 검출 정확도를 보임을 확인하였다.

This study is a one-group pretest-posttest design to evaluate the effect of problem-based learning (PBL) for patient safety on self-leadership, patient safety competencies, and reflective thinking of nursing students. The research was conducted from March 2 to April 15, 2022, in which 57 nursing students participated. PBL for patient safety was examined in a total of 8 sessions in the order of motivation, problem identification, task performance planning, problem-solving methods, summary and solution, presentation, and evaluation. The following topics of patient safety were selected for each team: nursing records, high-alert medication, medication error and intravenous fluid regulation, blood transfusion care, fall, bedsore, infection control, and pain management. We provided feedback on the learning process and outcomes of nursing students. According to the results, self-leadership showed a statistically significant improvement in self-expectations (t=2.60, p=0.01), goal setting (t=2.84, p<0.01), self-reward (t=3.32, p<0.01), and self-criticism (t=2.32, p=0.02). Patient safety competencies showed a statistically significant improvement in patient safety knowledge (t=13.05, p<0.001) and patient safety skills (t=4.87, p<0.001) but not in reflective thinking. The results prove that PBL for patient safety is an effective teaching-learning strategy to improve self-leadership and patient safety competencies. Future studies must develop and validate specific and long-term teaching-learning methods to improve reflective thinking.
