최근 바쁜 일상 속에서 개인의 삶의 질과 활력을 높이기 위해 여가활동에 대한 관심이 증가하고 있고 그 중에서 독서는 꾸준한 사랑을 받고 있는 여가 활동이다. 그 중 소설의 출판량은 다른 타 장르에 비해 가히 압도적이다. 하지만 소설은 개인의 취향에 영향을 많이 받는다는 특징이 있어 사용자에게 적합한 소설을 추천하기란 기존의 시스템으로는 한계가 있다. 따라서 본 논문에서는 클라우드 컴퓨팅 시스템인 AWS(Amazon Web Service)를 이용하며 사용자의 개인 성향과 협업 필터링 방법을 이용하여 각각의 개인 성향에 적합한 소설을 추천하는 시스템을 제안한다.

난독증은 정상적인 지능에도 불구하고 문장을 읽기가 어려운 독서 장애다. 난독증 진단 방법은 ADHD처럼 증상 체크리스트가 없다. 지적장애를 판정할 때 사용하는 웩슬러 지능검사 같은 전 세계인이 사용하는 아주 보편화된 심리검사도 없다. 미국 진단기준의 최신판인 DSM-5에도 어떤 검사를 해서 기준점수 아래여야 진단할 수 있다고 명확히 써놓지 않았다. 본 논문에서는 이를 해결하기 위해 글자, 단어, 문장, 문단의 단위를 설정하여 화면에 출력하고 아이트래커를 활용하여 읽는 사람의 시선 데이터를 수집하여 히트맵으로 분석한다.

Motivated by people highlighting important phrases while reading or taking notes we propose a neural network training method by highlighting defective pixel areas to classify effectively defect types of images with complex background textures. To verify our proposed method we apply it to the problem of classifying the defect types of tire band fabric images that are too difficult to classify. In addition we propose a backlight highlighting technique which is tailored to the tire band fabric images. Backlight highlighting images can be generated by using both the GradCAM and simple image processing. In our experiment we demonstrated that the proposed highlighting method outperforms the traditional method in the view points of both classification accuracy and training speed. It achieved up to 13.4% accuracy improvement compared to the conventional method. We also showed that the backlight highlighting technique tailored for highlighting tire band fabric images is superior to a contour highlighting technique in terms of accuracy.

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.

최근 라이프 로그의 수집과 관리에 관련된 연구가 많이 진행 중에 있다. 또 핸드폰 카메라, 디지털 카메라, 캠코더 등의 발전으로 자신의 일상생활을 비디오로 저장하고, 인터넷을 통해 공유하는 사람도 증가하고 있다. 비디오 데이터는 많은 정보를 포함하고 있는 라이프 로그의 한 예로. 동영상의 촬영 및 수집이 활발해짐에 따라 동영상의 메타정보를 생성하고, 이를 이용해 동영상 검색과 관리에 이용하려는 연구들이 진행 중이다. 본 논문에서는 라이프 로그를 수집하고 수집된 동영상과 라이프 로그를 이용하여 의미정보를 추출하는 시스템을 제안한다. 의미정보란 사용자의 행동을 나타내는 정보로써 컴퓨터 사용, 식사, 집안일, 이동, 외출, 독서, 휴식, 일, 기타로 9가지의 의미정보를 추출한다. 제안하는 방법은 사용자로부터 GPS, 가속도센서, 캠코더를 이용해 실제 데이터를 수집하고, 전처리 과정을 통하여 특징을 추출한다. 이때 추출될 특징은 위치정보와 사용자의 상태정보 그리고 영상처리릍 통한 RGB와 HSL 색공간의 요소와 MPEG-7의 EHD(Edge Histogram Descriptor). CLD(Color Layout Descriptor)이다. 추출된 특징으로부터 사람 행동과 같은 불안정한 상황에서 강점을 보이는 확률모델 네트워크인 베이지안 네트워크를 이용하여 의미정보를 추출한다. 제안하는 방법의 유용성을 보이기 위해 실제 데이터를 수집하고 추론하고 10-Fold Cross-validation을 이용하여 데이터를 검증한다.

In this paper, we will examine the theoretical background and educational methodological basis of Novel engineering class cases published to date. For this purpose, we selected and investigated 30 Novel engineering-related academic papers and dissertations published from 2016 to 2023. As a result, the theoretical background is Seymour Papert's constructionism and Vygotsky's socio-cultural constructivism, and the educational methodological basis is creative problem-solving learning, problem-based learning, interdisciplinary convergence class, action learning, associating reading and writing education, possibility with integrated curriculum. We hope that this study will solidify the theoretical value of the Nobel Engineering convergence teaching model and serve as an alternative for teachers preparing for future education.

In this study was groped a plan for an idea and method of design as the alternative of cure of cocial defect. Ailo, it was referred how an idea and method of design could be used for a cure of social defect and it was considered that an educational form that to actualize the idea and method of design is the basic structure of a cure or improvement of social defect. This educational form actualities exactly the 'media'which the idea and method of design pursue. In the end, an effect of media could probably make social change be practical.

Some of the possible effects of revitalizing school libraries are improved personality education and an acquisition of the basic, as well as cultural, knowledge through expanded reading opportunities. The goal of school education is to increase the students' intellectual quality by providing structured education curriculums. In order to meet this goal, there has been increased interest in ways to enhance academic achievements or to increase the cognitive level of the students. In this study, we focused on the effects of school libraries on learning capabilities. To measure the learning capabilities, we used academic achievements as the evaluation criteria. Based on the statistical analysis, we found that the collection types and the reasons for using school libraries influenced the academic achievements more than the frequency of using school libraries. However, the influences of economic and social factors were too great in comparison to other factors. This paradoxically shows the importance of public education and the school libraries' role in education in general. In summary, school libraries should provide good quality reading experiences as well as methods to collect, manage, and use information to the students. These efforts will positively impact the academic achievements of the students.

In Korea, the word, 'Literary Therapy' can be replaced by 'Bibliotherapy', 'Journal Therapy', 'Writing Therapy', 'Poem Therapy', 'Integrated Literary Therapy', or 'Imaginary-Oriented Poetry Therapy', and so on. This study, intended on people related to literary therapy, uses Q-methodology as useful research method of objectifying abstract concepts which can be perceived differently according to individual experience or perception, to investigate types of literary therapy's subjective perceptions. The result of study can be analyzed by four types: The first type is 'Pursuing Generalization', the second type is 'Considering the Therapist', the third type is 'Emphasizing the Integration', and the forth type is 'Maximizing the literary therapy'. Through this result of the study, we can find the responsibility of literary therapy as a leader of cultural, artistic therapy to break down various pathological situations which contemporary society have.

The purpose of this study is to develop an automatic classification system for recommending appropriate books of 9 enneagram personality types, using book information data reviewed by librarians. Data used for this study are book review of 501 recommended titles for children and young adults from National Library for Children and Young Adults. This study is implemented on the assumption that most people prefer different types of books, depending on their preference or personality type. Performance test for two different types of machine learning models, nonlinear kernel and linear kernel, composed of 360 clustering models with 6 different types of index term weighting and feature selections, and 10 feature selection critical mass were experimented. It is appeared that LIBLINEAR has better performance than that of LibSVM(RBF kernel). Although the performance of the developed system in this study is relatively below expectations, and the high level of difficulty in personality type base classification take into consideration, it is meaningful as a result of early stage of the experiment.
