시뮬레이션을 비롯한 많은 다중 에이전트 환경에서는 중앙 집중 훈련 및 분산 수행(centralized training with decentralized execution; CTDE) 방식이 활용되고 있다. CTDE 방식 하에서 중앙 집중 훈련 및 분산 수행 환경에서의 다중 에이전트 학습을 위한 상태 행동 가치 기반(state-action value; Q-value) 다중 에이전트 알고리즘들에 대한 많은 연구가 이루어졌다. 이러한 알고리즘들은 Independent Q-learning (IQL)이라는 강력한 벤치 마크 알고리즘에서 파생되어 다중 에이전트의 공동의 상태 행동 가치의 분해(Decomposition) 문제에 대해 집중적으로 연구되었다. 본 논문에서는 앞선 연구들에 관한 알고리즘들에 대한 분석과 실용적이고 일반적인 도메인에서의 실험 분석을 통해 검증한다.

현재 산업용 로봇 팔의 경로 계획을 생성할 때, 로봇 팔 경로 계획은 로봇 엔지니어가 수동으로 로봇을 제어하며 최적 경로 계획을 탐색한다. 미래에 고객의 다양한 요구에 따라 공정을 유연하게 변경하는 대량 맞춤 시대에는 기존의 경로 계획 수립 방식은 부적합하다. 심층강화학습 프레임워크는 가상 환경에서 로봇 팔 경로 계획 수립을 학습해 새로운 공정으로 변경될 때, 최적 경로 계획을 자동으로 수립해 로봇 팔에 전달하여 빠르고 유연한 공정 변경을 지원한다. 본 논문에서는 심층강화학습 에이전트를 위한 학습 환경 구축과 인공지능 모델과 학습 환경의 연동을 중심으로, 로봇 팔 경로 계획 수립을 위한 심층강화학습 프레임워크 구조를 설계한다.

In this study a comparative analysis is conducted to evaluate TLSF(Teaching and Learning for a Sustainable Future) program, which is a module type environmental education program developed by UNESCO, and the Korean environmental education curriculum. The Korean environmental curriculum is mainly focused on conceptualization and the matters of fact. As a result, students may not be able to acquire contextualized and synthesized views on the environmental problems. The Korean environmental curriculum hardly supplies ample variety in the methods of teaching, learning and assessment, or the theories characteristic of the environmental education. Thus it would not make a useful material for teachers to reorganize various materials to be applied in class. TLSF program would be useful for a teacher to use in the environment education field because it supplies not only many various activities and samples for constructing a proper program but also the theoretical base and examples for education and assessment strategy. Finally, TLSF also offers the theoretical base of the environment education for the assessment, and it makes the best use of feedback from the environment educational field for improving its own quality. In conclusion, this study can be a meaningful preview for those who are involved in the process of developing of a curriculum, which consists of steps like formulating theories for developing a curriculum, organizing the curriculum contents, activating and evaluating a curriculum.

Humanities are as crucial as the technology itself in the intelligent information society. Human-centered convergence information technology (IT), which reflects emotional and human nature, can be considered a unique technology with an optimistic outlook in the unpredictable future. Based on this research background, this paper proposed an education model that can improve the IT humanities capabilities of various learners, including elementary and secondary students, prospective teachers, incumbent teachers, school managers, and the general public, through analysis of previous studies on convergence education models. Furthermore, the practical aspects of the proposed model were closely examined so that the proposed education model could be stably incorporated and utilized in the educational field. There are seven strategies for implementing the education model proposed in this paper, including research on textbooks, teaching and learning materials, activation of research results, maker space creation, global joint research, online education operation, developing living lab governance, and diversification of self-sustaining platforms for sustainable and practical education. In the future, validity verification through expert Delphi is required as a follow-up study.

This research points out the necessity of customized communication education for engineering students in the era of the Fourth Industrial Revolution. This paper also points out such problems of current communication education as presentation and discussion-focused 'Public Speech' exercises, absence of interests about social issues, and lack of interactive communication learning. In general, as the characteristics of their major education, engineering students are not aggressive in self-questioning and active communication rather than their sensitive reaction to the changes of the new era. Considering these characteristics of engineering students, this research emphasizes that future communication education should be deployed from the major-focused thinking to the development of convergent thinking, from the problem-solving to the problem-finding, and from the contentious thinking to the cooperative thinking. In addition, as a class design reflecting future trends, this research emphasizes, firstly the development of cooperative communication education model, secondly active utilization of SMART technology, and lastly the importance of customized-coaching for each student considering their own characteristics and requirements.

In spite of the rapid change of the technology, the university education cannot escape from the traditional form of classroom teaching. University education is assessed through listening the same content of lecture, completing the same assignment and test at the same time, same place. To prepare for the 4th industrial revolution, it is investigated to reorganize the curriculum(32.5%), strengthen the lifelong education(21.4%), expand the compulsory education(17.6%), expand the innovation school(13.7%), expand the educational finance(10.4%) as the field of education which need to be strengthen. The change of the education is essential to prepare for the 4th industrial revolution which creativity, collaboration, fusion, problem solving are the core ability. In this thesis, it is to be compared that the subjects opened in liberal arts of domestic and overseas university in this 4th industrial revolution and Basic Liberal Art Education Curriculum is promoted for the smooth management for preparing the future and taking the action to the change. Stereotyped and inflexible frame should be changed to 'Structure', 'Recognition', 'Attitude' for making the base of 'Diversity', 'Personalization', 'Flexibility' which are needed to uplift 'Imagination', 'Creativity' for education of the future and the new era.

This study has examined the current status of mathematics education departments by analyzing its curriculum and teaching methods. We analyzed data set of the number of faculty and students, curricula, textbooks and instructional methods among 23 mathematics education department in Korea. The data reveals that the curricula of the universities of education has shown that more content knowledge subjects are taught than pedagogy knowledge subjects. However, it is important to note that there is increasing emphasis on pedagogical content knowledge. In addition, the curricula of mathematics education departments deal with various aspects of pedagogical content knowledge. What matters is whether the system works for developing a sound and deep understanding of fundamental aspects of the subject matter in future mathematics teachers. The results of the study point to the importance of pedagogical content knowledge and to the essential components that can promote further understanding of effective teaching for preparing future teachers in mathematics education departments.

Education emphasizes problem-solving skills based on convergent thinking power in an era of rising uncertainty and rapid progress. This paper proactively designed e-Learning team teaching convergence liberal arts courses for prospective teachers by these social needs. It analyzed the empirical effects on the operation of the subjects to foster future talent who can converge and apply knowledge in various fields. The curriculum consisted of professors of mathematics, practical Arts, computer, and education, and was operated to convey convergent knowledge of information technology and humanities, and consisted of 15 liberal arts courses at J University. Besides, textbooks and teaching materials were also developed by the faculty. As a result of the primary research, prospective teachers who took the course generally showed high satisfaction with the class, especially for the faculty. The students' overall convergent thinking ability has increased to a statistically significant level (p<.01), and the students' major has been found to be irrelevant. On the other hand, it can be seen that communication, content convergence, and caring factors, excluding creativity factor, have all risen to a significant level.
