This study explored effective teaching-learning activities under the hybrid teaching model combining flipped learning, direct instruction, cooperative learning and distance learning. Subjects were 99 college students enrolled in 2 teacher preparation courses. Students evaluated effectiveness of 22 teaching-learning activities according to Likert scale at the end of the semester. As a result, all 22 teaching learning activities were considered effective more or less. They facilitated motivation, comprehension, participation, thinking, and led to mastery of the task. ② Activities scored low were 'questioning and answering at the beginning of online class', 'open book test'. ③ Hybrid teaching model was favored over traditional instruction. Open ended responses were consistent with the ones in the questionnaire. This research supports the notion that key teaching models to be combined for successful flipped learning in college setting are direct instruction and cooperative learning. Furthermore, effective and ineffective teaching strategies for flipped learning were found.

The purpose of this study was investigating effects of TBL (Team-based learning) on the academic achievements and learning satisfaction of university students. This study subjects were 46students in social welfare department. This study surveyed instructor-led classes and orientation of TBL, which is provided from the 1st week to 3rd week. Then, TBL was performed from 4th week to 14th week. The results were found by utilizing questionnaires and interviews through free form technology, which produced effective and measured responses. So academic achievements was improved significantly better than classical explanation teaching. And also learning satisfaction was improved with students' substantial amount, interesting and seamless interaction, active learning and participation, improved presentation technique, and competence in mutual communication. I suggest that TBL should be applied to other subjects.

Distance education, which emerged under the influence of both the rapid development of hi-tech information technology and the constructivism theory of learning, enables learners to acquire knowledge and skills needed by monitoring their learning process for themselves. Emphasis on web-based distance education and contructivism as a basis of learner-centered education does not mean that those education systems are performed without teachers or in noninterference. This study proposes a model of distance education system in which learners are taught in various levels of learning with the help of teacher agents. In the model teacher agents produce the learners' respective learning model considering the information on individual learners and also control the progress to the next step of learning with the result of the evaluation of learning accomplishment. The model of distance education system suggested in this study is able to help solve the problem that the learning resources web-based distance education provides were used only as objects of web search and to supply a basis of realizing learner-centered education.

Houshan's Comments on Poets and Poetry by Chen Shidao, one of the most famous comments on poets and poetry in the Northern Song Dynasty, is regarded as the early masterpiece of the literary critic genre called comments on poets an poetry. In particular, the theory on poetry of Houshan's Comments on Poets and Poetry reflected the overall literature fashion of the Song Dynasty, and captured the typical arguments of poetics in the Song Dynasty. The poet's character-building and accumulation of knowledge, the study of Du Fu and other poets and a quest for "No Trace" reveal the practice and aesthetics of the poets in the Northern Song Dynasty. So far, Chen Shidao has been known as a formalist poet, and he has actually focused on learning the rules of verse and learning classical poetry. But the final goal of his theory on poetry was a free creation, not the strict rules. He just thought that he could get the freedom of creation by constantly learning rules and building a poem. Therefore, his comments in Houshan's Comments on Poets and Poetry can not be regarded as simply formalist views. Because he wanted to achieve his ideal freedom of creation with elaborate formats and content.

본 논문에서는 비전 기술에 기반을 둔 손 모양 인식 시스템의 성능 향상을 위해 학습을 통해 손 모양과 손 구조 간 유사도를 결정하는 방법을 제안한다. 비전 센서에 기반을 둔 손 모양 인식은 손의 높은 자유도로 인한 자체 가림 현상과 관찰 방향 변화에 따른 입력 영상의 다양함으로 인해 인식에 어려움이 따른다. 따라서 비전 기반 손 모양 인식의 경우, 카메라와 손 간의 상대적인 각도에 제한을 두거나 여러 대의 카메라를 배치하는 것이 일반적이다. 그러나 카메라와 손 간의 상대적 각도에 제한을 두는 경우에는 사용자의 움직임에 제약이 따르게 되며, 여러 대의 카메라를 사용할 경우에는 각 입력된 영상에 대한 인식 결과를 최종 인식 결과에 반영하는 방식에 대해서 추가적으로 고려해야 한다. 본 논문에서는 비전 기반 손 모양 인식의 이러한 문제점을 개선하기 위하여 인식의 과정에서 사용되는 손 모양 특징을 손 구조적인 각도 정보와 손 영상 특징으로 나누고, 학습을 통해 각 특징 간 연관성을 정의한다.

In this paper, we suggest the method to improve the existing method leaning context-free grammar(CFG) using tabular representation(TBL) as a chromosome of genetic algorithm in grammatical inference and show the more efficient experimental result. We have two improvements. The first is to improve the formula to reflect the learning evaluation of positive and negative examples at the same time for the fitness function. The second is to classify partitions corresponding to TBLs generated from positive learning examples according to the size of the learning string, proceed with the evolution process by class, and adjust the composition ratio according to the success rate to apply the learning method linked to survival in the next generation. These improvements provide better efficiency than the existing method by solving the complexity and difficulty in the crossover and generalization steps between several individuals according to the size of the learning examples. We experiment with the languages proposed in the existing method, and the results show a rather fast generation rate that takes fewer generations to complete learning with the same success rate than the existing method. In the future, this method can be tried for extended CYK, and furthermore, it suggests the possibility of being applied to more complex parsing tables.

The free learning semester system focuses on the activation of career education of middle school students as an educational policy that links career recognition in elementary school, career search in middle school, and career planning in high school. This system was fully implemented in 2016 and public libraries also provided various programs. This study analyzed the free learning semester system programs of public libraries in Busan city and demonstrated the contribution of local development. As a result, career and job search, career exploration and experience, and information literacy enhancement programs contributed to local knowledge culture, reading culture, learning culture, living culture and leisure culture. However, contribution of reading exhibitions, job experience, information literacy enhancement to the leisure culture and local economy were limited. Therefore, it is desirable that all libraries should add programs related to knowledge ecosystem structure, digital information gap, human healing, social environment issues, future job prospects, and provide information literacy programs.
