본 연구팀에서는 기존의 기호주의 전문가 시스템의 경우 지식표현 체계가 의미구조를 반영하지 못함으로써 발생하는 경직성문제를 해결하기 위해 CSN(Connectionist Semantic Network) 모델을 제안하였다. 그러나 CSN모델은 상위개념간의 관계를 표현하기 위해 단순한 전향 신경망을 사용함으로써 상위개념간의 일반적이고 구조화된 지식표현 및 추론에 어려움이 있었다. CSN 모델의 이런 문제점을 위해 본 논문에서는 상위개념간의 일반적이고 구조화된 지식표현과 추론이 용이한 기호주의 표현 체계와 이 표현 체계 안에 효과적으로 의미구조를 반영할 수 있는 연결주의 학습 모델인 CSN을 결합한 하이브리드 구조를 제안하고, 실험을 통하여 제안된 하이브리드 구조의 타당성을 보인다.

In the learning of mathematics, students experience the semiotic activities of representing and interpreting mathematical signs. We called these activities as the representing and interpreting of mathematical signs. On the foundation of Peirce's three elements of the sign, we analysed that students constructed the representamen to interpret the concept of correlation as for the object, "as one is taller, one's size of foot is larger" 4 middle school students who participated the gifted center in Seoul, arranged the statistical data, constructed their own representamen, and then learned the conventional signs as a result of the whole class discussion. In the process, students performed the detailed representing and interpreting of signs, depended on the templates of the known signs, and interpreted the process voluntarily. As the semiotic activities were taken place in this way, it was needed that mathematics teacher guided the representing and interpreting of mathematical signs so that the representation and the meaning of the sign were constructed each other, and that students endeavored to get the negotiation of the interpretants and the representamens, and to reach the conventional representing.

This study investigates how learners extract their implicit knowledge into explicit form of the knowledge. The process of implicit-explicit transfer is known to help learners to reconstruct and refine their knowledge which was constructed before in some ways. Also we investigate which types of explicit form are more effective when it is delivered to other learners. In a classroom-based learning environment, students take educational content that is delivered by instructor and go through the process in which they try to fit the content into their cognitive structure by reconstructing the knowledge into their cognitive model. When they try to deliver their own cognitive model for the knowledge to other learners, they have to transform it into explicit form, and through the process, they reconstruct and refine the cognitive model of the knowledge, and find effective and appropriate way to express it. In this research, we experimented the process on a group of 77 college students and analyzed the results. We also did peer evaluated experiments to see which types of explicit format and factors are more effective than others. The results indicate that the types of explicit form of implicit knowledge play an important role in effectiveness of learning.

This discussion looked at how emotional adjectives are connected in the format [[emotional adjective + '-ko(and)'] + emotional adjective]. As a result, it was confirmed that there are quite a few cases in which two or more emotional adjectives are used to express emotions in Korean. This can help Korean learners understand and express the individual lexical meanings of emotional adjectives more clearly by identifying emotional adjectives that are used together with the corresponding configuration. It was believed that it could help Korean language learners express complex emotions or create rich emotional expressions when expressing their emotions in Korean. It is hoped that the examples and frequency of [[emotional adjective+'-ko(and)'+emotional adjective] shown in this discussion will be of some help in teaching and learning Korean emotional vocabulary.

In the process of solving a linear equation, some questions had equal sign('=') relation properly, while other questions did not have equal sign('=') relation properly. Since whether students could express equal sign('=') relation properly or not is determined by questions, the direction for teaching should be instituted, and instruction and teaching should be conducted by comparing and analyzing after conducing tests on may items. Most of students who got the answer for items without the method of solving a linear equation solved the items using binomial. For questions asking to solve using the characteristic of equality, most of students solved the questions using binomial instead of using the characteristic of equality. Therefore, instruction and learning to solve equations using both the characteristic of equality and binomial have to be achieved.

The accessibility and effect of cartoon on children are very significant. Since cartoon is a medium of conveying information through text and pictures, it has a characteristic of being easily approached by children than any other medium. Its accessibility to children is inevitably more exceptional than any other medium in the sense that it is a method of not only telling or reading stories but also showing stories. The main audience of is children. It has a characteristic of being easily accepted by children since it's mythology seen in cartoon than read in text. However, gods conducts are full of unethical expressions. Sexual expressions of intermarriages between mother and son, between brother and sister and between uncle and niece, as well as extramarital intercourse are very unethical that could have negative effects on children. This study analyzed the unethical expressions of gods that could have negative effects on children at current point in time. Zeus was often unfaithful to his wife with many stories about the children of Zeus that were created from extramarital intercourse. Standard of value on rational decision has been established for adult readers, but children can readily accept things since they lack their own rational decision on what's right and wrong. As an alternative to children's uncritical observatory study, there is a need for author's intervention to help children form desirable values. The purpose of this study is to analyze the sexual expressions of Zeus and gods in that could affect children's social study.

상호참조해결은 문서에서 명사, 대명사, 명사구 등의 멘션 후보를 식별하고 동일한 개체를 의미하는 멘션들을 찾아 그룹화하는 태스크이다. 딥러닝 기반의 한국어 상호참조해결 연구들에서는 BERT를 이용하여 단어의 문맥 표현을 얻은 후 멘션 탐지와 상호참조해결을 동시에 수행하는 End-to-End 모델이 주로 연구가 되었으며, 최근에는 스팬 표현을 사용하지 않고 시작과 끝 표현식을 통해 상호참조해결을 빠르게 수행하는 Start-to-End 방식의 한국어 상호참조해결 모델이 연구되었다. 최근에 한국어 상호참조해결을 위해 구축된 ETRI 데이터셋은 WIKI, QA, CONVERSATION 등 다양한 도메인으로 이루어져 있으며, 신규 도메인의 데이터가 추가될 경우 신규 데이터가 추가된 전체 학습데이터로 모델을 다시 학습해야 하며, 이때 많은 시간이 걸리는 문제가 있다. 본 논문에서는 이러한 상호참조해결 모델의 도메인 적응에 Continual learning을 적용해 각기 다른 도메인의 데이터로 모델을 학습 시킬 때 이전에 학습했던 정보를 망각하는 Catastrophic forgetting 현상을 억제할 수 있음을 보인다. 또한, Continual learning의 성능 향상을 위해 2가지 Transfer Techniques을 함께 적용한 실험을 진행한다. 실험 결과, 본 논문에서 제안한 모델이 베이스라인 모델보다 개발 셋에서 3.6%p, 테스트 셋에서 2.1%p의 성능 향상을 보였다.

지식 정보화 사회, 인터넷 매체의 시대로 접어들면서 컴퓨터와 관련 기술의 발달은 학습의 범위를 이라 불리는 가상공간까지 확대하였고, 교육에 있어서도 사이버 학교 시대가 도래하여 국어 교육도 변화를 필요로 하고 있다. 이에 본 연구에서는 학생들의 흥미를 유발할 수 있으며 즐겁게 학습할 수 있는 웹 콘텐츠를 제작하여 활용함으로써 교과서 속 원작동화를 찾아 읽어보고, 다양한 독후 표현 활동을 통해 학생들의 문학 감상 능력과 표현능력의 신장을 꾀 할 수 있도록 국어과 읽기 교과서에 있는 54편의 동화내용 중 각 학년 6편씩 36편의 동화내용의 원작 작품을 찾아 설계하고 구현하였다. 본 콘텐츠를 활용하면 학생들의 문학 감상 능력 및 표현 능력의 신장에 효과적일 것이라 기대된다.
