본 논문에서는 규칙 기반의 4성부 합창 음악 생성 과정에 화성 진행 학습 모델을 적용해 보고자 한다. 제안하는 시스템은 32음의 멜로디를 입력으로 받아 다른 세 성부를 화성학의 규칙에 맞게 완성시켜 주며, 그 과정에서 사용하는 화성 진행을 CRBM 모델을 이용하여 예측한다. 학습 데이터는 화성학 교육 자료집에서 다수 발췌하였으며, 화성 진행을 조성에 독립적으로 추출하여 주어진 데이터를 효과적으로 활용할 수 있도록 하였다. 학습 모델을 적용한 결과물이 기존의 규칙 기반 4성부 합창 음악에 비해 보다 자연스러운 진행을 보임이 확인되었다.

이 연구의 목적은 가정 교과와 미디어 리터러시 교육의 관련성을 알아보는 것이다. 이를 위해 중학교 '기술·가정 2' 교과서 12종의 학습 자료를 분석하였다. 분석 기준으로 '미디어 리터러시 수행 목표'를 선택한 후, 빈도 및 내용 분석 및 세 번의 협의를 통해 미디어 자료의 분포와 '미디어 리터러시 수행 목표'의 반영을 분석하였다. 본 연구의 결과는 다음과 같다. 첫째, 12종 교과서의 전체 학습자료 중 미디어자료를 이용한 학습자료는 39.6%를 차지하였고 출판사별로 미디어자료를 이용한 학습자료의 빈도와 비중에서 차이가 있었다. 미디어 유형에 따라서는 '인쇄' 68.3%, '영상' 16.7%, '디지털' 13.5%로 분포하였고, 단방향 미디어의 사용은 86.5%로 대부분을 차지하였다. 둘째, 출판사별로 미디어 리터러시 수행목표가 반영된 학습자료의 빈도와 비중에서 차이가 있었고 총체적인 미디어 리터러시 함양을 위해 학습내용의 보완이 필요하였다. 학습자료에 반영된 미디어 리터러시 수행목표 중 '의미 이해와 전달'은 58.8%로 가장 많이 반영된 수행목표였지만 미디어를 통한 쌍방향 소통은 부재하였다. 이러한 교과서 분석 결과를 바탕으로 가정과 미디어 리터러시 수행목표를 수정하여 제안하면 다음과 같다. '의미 이해와 자기표현', '소통과 사회참여', '책임있는 미디어 이용', '감상과 향유', '미디어 기술 활용', '정보 검색과 선택', '창작과 제작', '비판적 이해와 평가'이다. 이상의 연구 결과를 바탕으로 현장의 가정 수업에서 가정과 미디어 리터러시 수행목표를 학습요소로 반영하여 가정과 교육에서 융합적인 미디어 리터러시 교육을 수행하는데 도움이 되는 기초 자료로 활용되길 기대한다.

We introduce an introductory engineering education course for engineering majors and non-engineering majors. This course does not require any previous knowledge and experience on engineering. It requires strong curiosities and imaginations on current and future society we live in, where technology is inseparable ingredient. Course encourages attendees to explore fundamental issues of engineering: what is proper technology and what are proper ways of exercising engineering, issues dealt in soft engineering. Since course topics cover many aspects of technology, traditional learning methods fail to be successful and efficient. Various efficient learning methods have been proposed and implemented. We utilize various interactive tangible media, which include simulated thought experiments and physical media experiences. About 20 episodes in short film format are produced based on scenario written according to related issues selected. Physical media like interactive robots are introduced for attendees' stimulated experiences. We summarize our exciting experiments on interactive teaching experiences at Pusan National University which include on/off-line interactions, assignments, projects, and evaluations.

This study explored how a particular social media can be used to supplement elementary-level Korean language course in the US public university. The researchers administered a survey measuring students' patterns and habits of social media use. Based on the survey results, researchers designed six different types of learning materials and uploaded them regularly to Instagram throughout the semester. At the end of the semester, a survey was conducted to find out students' satisfactory level. From the 44 students' responses, the study found out that using Instagram 1) is more accessible to students than any other learning management system, 2) is fun and students are willing to participate, 3) increased the target language exposure and authentic language use, 4) increased interaction between teachers, students and even other native speakers, and 5) is helpful to improve listening and other language skills. The study closes with the suggestion for further experimental studies.

HAR(Human Action Recognition) such as anomaly and object detection has become a trend in research field(s) that focus on utilizing Artificial Intelligence (AI) methods to analyze patterns of human action in crime-ridden area(s), media services, and industrial facilities. Especially, in real-time system(s) using video streaming data, HAR has become a more important AI-based research field in application development and many different research fields using HAR have currently been developed and improved. In this paper, we propose and analyze a deep-learning-based HAR that provides more efficient scheme(s) using an intelligent AI models, such system can be applied to media services using RGB video streaming data usage without feature extraction pre-processing. For the method, we adopt Slowfast based on the Deep Neural Network(DNN) model under an open dataset(HMDB-51 or UCF101) for improvement in prediction accuracy.

This study aims to provide implications for mobile foreign language vocabulary learning app by analyzing the effects of mobile vocabulary learning app based on character animation. For this purpose, we applied the learning application designed with character animation and text, and the application designed with text only to two groups of learners, and analyzed the effect. As a result, we found that application designed with character animation and text was useful in recognition frequency and duration concerning learning. Regarding learning outcomes, we found that it is useful not only in memory but also in learning interest and motivation. This study provides implications for learning method and design development of mobile-based foreign language vocabulary learning application which actively using recently.

E-learning is a new teaching model nowadays, and Virtual Reality (VR) technology is reported that the use of virtual reality as an education tool can increase student interests, understanding, and creative learning because of encouraging students to learn by exploring and interacting with the information on the virtual environment. Besides that, LEGOs have long been the favorite of many children. LEGOs provide a mechanism to understand and do for many concepts from spatial relationships to robotics platforms. In this paper, we present a virtual reality application based on the assembly of LEGO-Like bricks to increase math and science learning by improving spatial thinking. It not only encourages students to pursue careers in science, technology, engineering, or mathematics but also enhances learner's ability to analyze and solve problems. The application is built by Processing 2.0 as the easier programming language which is a top-down approach to build the 3D interactive program.

Modern technology offers many ways to enhance teaching and learning that in turn promote the development of tools for educational activities both inside and outside the classroom. Many educational programs using the augmented reality (AR) technology are being widely used to provide supplementary learning materials for students. This paper describes the potential and challenges of using GeoGebra AR in mathematical studies, whereby students can view 3D geometric objects for a better understanding of their structure, and verifies the feasibility of its use based on experimental results. The GeoGebra software can be used to draw geometric objects, and 3D geometric objects can be viewed using AR software or AR applications on mobile phones or computer tablets. These could provide some of the required materials for mathematical education at high schools or universities. The use of the GeoGebra application for education in Laos will be particularly discussed in this paper.
