The purpose of this paper is to investigate the historical changes of information literacy instruction in Japanese school libraries and in-depth research into recent educational situations. Related literature researches, the publication of School Library Association, The Courses of Study have been reviewed in this paper. As results of this research, information literacy education in Japanese school library has been developed from introductory period of the library use guidance after late 1940's, seek period of teaching method development after late 1950's, establishment period of information literacy instruction after 1980's, and enlargement period of inquiry based learning after 2000's.

This study aimed to develop a music teaching-learning program for secondary students with intellectual disabilities in special education settings based on music therapy approach. Designed lesson plans included three learning domains based on the guidelines from 2008 amendments to the special education music curriculum: Perception, expression, and appreciation. Within the domains, instruction topics and its corresponding contents were re-structured as considered more appropriate and effective for implementing music classes for this population. With consideration of therapeutic goals as well as educational goals, student activities and teacher activities were designed and the activities were presented at three levels depending on students' functional levels. Integrating these instructional components into an actual plan, this study presented yearly (for 20 hours of classes) and monthly lesson plans. The developed lesson plans were reviewed and verified by related professionals including special class teachers and music therapists. As systematic and well-organized lesson plans, the results from this study would provide basic music education resources for students with intellectual disabilities in special education settings. It would also enable the discussion on the music therapy-based teaching-learning program as new methodological and strategic ideas applicable to future special education.

딥러닝을 이용한 침수해석은 강우자료와 그에 대한 1차원 EPA-SWMM 결과인 총월류량을 인공신경망에 학습시키고, 학습시킨 인공신경망을 테스트하기 위해 또다른 강우자료를 인공신경망으로 예측해서, 이것이 해석결과를 얼마나 잘 나타내는지 확인하고, 인공신경망이 모의한 총월류량을 잘 나타낸다면 인공신경망을 잘 학습시킨 것으로 판단하여 새로운 강우가 발생했을 때 새로운 강우자료에 대해 매번 새로 1차원, 2차원해석을 하는 것을 대신하여 인공신경망만으로 총월류량을 예측할 수 있게 되는 것이다. 강우자료를 입력자료로 사용하게 되는데, 강우량만으로는 그 강우의 특성을 전부 나타낸다고 할 수 없기 때문에 지속기간과 총강우량, 왜도(skewness), 표준편차를 추가적인 입력자료로 사용한다. 1차원, 2차원 해석결과인 총월류량은 입력자료에 대한 타깃자료가 되어, 인공신경망을 테스트하거나 실제로 이용할 때 비슷한 지속기간과 총강우량, 왜도, 표준편차를 가진 강우가 발생했을 때 타깃자료를 이용해 총월류량을 예측하는 것이다. 인공신경망이 얼마나 잘 학습되었는지 확인하기 위해서 침수지도를 작성해볼 필요가 있다. 1차원, 2차원 모의해석으로 나온 총월류량과, 인공신경망을 이용해 예측한 총월류량을 이용해 각각 침수지도를 작성하여 시각적 자료로 변환하여 비교하고, 침수지도가 일치한다면 인공신경망이 잘 학습되었다고 판단할 수 있고, 새로운 강우가 발생하면 학습시킨 인공신경망을 통해 1차원, 2차원 모의해석을 하지 않고도 총월류량을 예측할 수 있다.

One of the object on math education is low-level students. To improve this problem and to instruct efficiently I developed "let's play figures" instruction and learning system. This system reconstructed diagram part of math into 5steps to achieve the goal of tailored education to fit student's learning level. Based on this, the game can be used as the teaching method to enhance the student's interest and self-studying ability and also this system has been developed for the education connected to home.

The purpose of this study is to identify the characteristics and types of errors in the conceptual image of Korean language learners according to the types of terms in mathematics that are the basis for solving mathematical word problems, and to prepare basic data for effective teaching and learning methods in solving the word problems of Korean language learners. To do this, a case study was conducted targeting four Korean language learners to analyze the specific conceptual images of terms registered in curriculum and terms that were not registered in curriculum but used in textbooks. As a result of this study, first, it is necessary to guide Korean language learners by using sufficient visualization material so that they can form appropriate conceptual definitions for terms in school mathematics. Second, it is necessary to understand the specific relationship between the language used in the home of Korean language learners and the conceptual image of terms in school mathematics. Third, it is necessary to pay attention to the passive term, which has difficulty in understanding the meaning rather than the active term. Fourth, even for Korean language learners who do not have difficulties in daily communication, it is necessary to instruct them on everyday language that are not registered in the curriculum but used in math textbooks. Fifth, terms in school mathematics should be taught in consideration of the types of errors that reflect the linguistic characteristics of Korean language learners shown in the explanation of terms. This recognition is expected to be helpful in teaching word problem solving for Korean language learners with different linguistic backgrounds.

현장에서 수업을 하다 보면 의외로 학생들이 곱셈구구는 잘 외우고 있지만 곱셈의 개념에 대해서는 잘 모르고 있다는 것을 많이 발견할 수 있다. 이것은 곱셈에 대한 개념을 도입할 때 학생들이 왜 곱셈을 배우는가에 대해서 스스로 절실하게 생각해 보고 발견해 보는 경험이 부족했기 때문이라고 생각한다. 곱셈이 왜 필요하고 곱셈식으로 나타내는 것이 얼마나 좋은 방법인지 학생들이 깨달아 덧셈구조에서 곱셈구조로의 개념의 변화가 일어날 수 있도록 지도한다면 이러한 문제점을 어느 정도 해결할 수 있지 않을까 생각해본다. 따라서, 본 연구에서는 자연수의 곱셈에 대한 이론적 배경과 교육과정을 알고 이를 바탕으로 수학교육 이론에 근거한 자연수의 곱셈의 교수-학습 지도 방안에 대하여 거시적 입장에서 고찰해 보고자 한다.

This paper is the case study how we can apply the appropriate teaching method in order to correct the misconception of middle and high school students in preservice teachers' education. Through the review of previous research and literature, we categorized students' misconception and sought the teaching method to teach preservice teachers. During this process, we did according to PBL and preservice teachers also tried to find the teaching method for students. And thus we were able to suggest the appropriate teaching method which was effective in correcting the misconception of middle & high school students along with their fine understanding of mathematical concepts. Further, preservice teachers acknowledged cooperative teaching & learning and the importance of it as well as the self-directed teaching and learning.

This study examined the relationship between homeroom teachers' transformational leadership, high school students' satisfaction in school life, and learning motivation. The researchers selected boys and girls' general high school as the target population and gathered survey data. The number of participants was 606; these were students from first and second grades. Questionnaires on teachers' transformational leadership, students' learning motivation, and satisfaction in school life were measured. T-tests showed the following: As a result of the analysis of the difference of transformational leadership, the average of the teachers with careers spanning over 15 years was statistically significantly higher than those whose career spanned over less than 5 years. The group which perceived the transformational leadership of the homeroom teacher as high showed higher motivation scores than the group with lower perception. The means were statistically significant in all the sub-variables. In school - life satisfaction, the average of the former group which perceived the transformative leadership of the homeroom teacher as high was significantly higher than that of the other group.

최근 연구에서 기계학습 중 지도학습 방법으로 개체명 인식을 하고 있다. 그러나 지도 학습 방법은 데이터를 만드는 비용과 시간이 많이 필요로 한다. 본 연구에서는 주석 된 말뭉치를 사용하여 지도 학습 방법을 사용 한다. 의생명 개체명 인식은 Protein, RNA, DNA, Cell type, Cell line 등을 포함한 텍스트 처리에 중요한 기초 작업입니다. 그리고 의생명 지식 검색에서 가장 기본과 핵심 작업 중 하나이다. 본 연구에서는 순환형 신경망과 워드 임베딩을 자질로 사용한 조건적 임의 필드에 대한 성능을 비교한다. 조건적 임의 필드에 N_Gram만을 자질로 사용한 것을 기준점으로 설정 하였고, 기준점의 결과는 70.09% F1 Score이다. RNN의 jordan type은 60.75% F1 Score, elman type은 58.80% F1 Score의 성능을 보여준다. 조건적 임의 필드에 CCA, GLOVE, WORD2VEC을 사용 한 결과는 각각 72.73% F1 Score, 72.74% F1 Score, 72.82% F1 Score의 성능을 얻을 수 있다.

뉴스 기사는 반드시 객관적이고 넓은 시각으로 정보를 전달하지 않는다. 따라서 뉴스 기사를 기존의 추천 시스템과 같이 개인의 관심사나 사적 정보를 바탕으로 선별적으로 추천하는 것은 바람직하지 않다. 본 논문에서는 최대한 객관적으로 다양한 시각에서 비슷한 사건과 인물에 대해서 판단할 수 있도록 유사도 기반의 기사 추천 모델을 제시한다. 길이가 긴 문서 사이의 유사도를 측정하기 위해 GPT2 [1]언어 모델을 활용했다. 이 과정에서 단방향 디코더 모델인 GPT2 [1]의 단점을 추가 학습으로 개선했으며, 저장 공간의 효율과 핵심 문단 추출을 위해 BM25 [2]함수를 사용했다. 그리고 준 지도 학습 [3]을 통해 유사도 레이블링이 되어있지 않은 최신 뉴스 기사에 대해서도 자가 학습을 진행했으며, 이와 함께 길이가 긴 문단에 대해서도 효과적으로 학습할 수 있도록 문장 길이를 기준으로 3개의 단계로 나누어진 커리큘럼 학습 [4]방식을 적용했다.
