The world is changing fast from the information society to the knowledge society as the amount of knowledge exploded over through development of the information communication technology. In this situation, mobile learning based on the mobile devices (PDAs, Cellular phone, Tablet PC, etc) offers the opportunity to assist each individual and group to learn anytime, anywhere. The purpose of this study is to discuss development direction of game styled contents for mobile learning. we introduce the development direction and prototypes of mobile learning contents focused on game-styled activities as the alternative to make up for the weak points of the mobile devices.

본 논문에서는 반몰입형 가상현실 시스템인 반응형 멀티미디어 시스템(RMS: Responsive Multimedia System)을 이용한 개인화된 스토리텔링 기법을 제안한다. 인간은 글, 그림, 영상 기술 등을 이용한 다양한 스토리텔링 기법을 개발해 왔으며, 가상 현실 기술을 통하여 기존의 멀티미디어보다 한차원 높은 수준의 스토리텔링을 가능하게 하였다. 제안된 스토리텔링 기법은 테이블 형태의 다감각 사용자 인터페이스, 사용자 정보 처리와 위치기반 이벤트를 결정하는 컨텍스트 인식 응용 모델 (vr-UCAM), 그리고 가상환경 네비게이션과 변화, 캐릭터의 애니메이션을 가능케 하는 가상공간 관리기로 구성된다. 제안된 스토리텔링 기법은 다감각 사용자 인터페이스를 통하여 직관적인 상호작용을 가능하게 한다. 그리고 컨텍스트 인식 응용 모델을 활용하여 사용자 개인정보를 스토리에 적용하여 개인화된 스토리가 전개될 수 있도록 한다. 그리고 가상 환경의 네비게이션, 가상 캐릭터, 날씨 및 환경의 변화 등을 조절하여 실감있게 스토리가 전개되도록 한다. 제안된 스토리텔링 환경을 검증하기 위해 운주사에 얽힌 설화를 기반으로 가상 운주사 체험 시스템을 구현하였다. 이를 통해, 반응형 멀티미디어 시스템을 이용한 스토리텔링의 가능성을 검증하였으며, 컨텍스트 인식 응용 모형을 활용한 개인화된 스토리텔링을 선보였다. 제안된 스토리텔링 기법은 문화교육, 에듀테인먼트, 예술 분야에 활용될 것으로 기대된다.

This study attempted to find out the factors affecting the self-directed learning ability of nursing students who took online lectures. The research method was a structured questionnaire survey targeting 2nd to 4th grade nursing college students, and the analysis method was analyzed by t-test, ANOVA, and multiple regression analysis. As a result of the study, the self-directed learning ability of nursing college students was an average of 3.48 points out of 5 points, and it was found that learning immersion had the greatest effect on self-directed learning ability. Based on the results of this study, it will be necessary to establish a quality education system and the efforts of instructors who apply various lecture methods or customized lecture programs so that learners can immerse themselves in learning in order to improve learners' self-directed learning ability.

In the recent education market, Edutech technology, in which various digital technologies are grafted into the education, is being actively applied due to the 4th industrial revolution and the development of ICT. In particular, realistic experiential learning contents that can provide realistic and immersive learning in a virtual space are in the spotlight and are being expanded to each field. However, in the field of Korean medicine education, the introduction of ICT is delayed due to the nature of Korean medicine, difficulties in apprenticeship education, quantitative education, and the absence of an objective evaluation system. Therefore, in this study, we propose a digital technology application for acupuncture and acupuncture points, where practice is particularly important in Korean medicine. Various methods of acupuncture and acupoints education using AR, MR, IoT and Touch-Display Table will provide an opportunity to change the paradigm of Korean medicine education and further contribute to the globalization of Korean medicine.

In recent years, training systems in various industrial fields have been made using virtual reality (VR) technology and widely used in education. Virtual reality based training system is safe, there is no waste of material, and there are many advantages to be able to practice anytime and anywhere. For example, virtual reality welding training simulation system is widely used for field worker because it can perform actual joining of steel plate in immersive environment. At this time, realistic representation of the steel plate joint is important to maximize the effectiveness of the training, but existing techniques have limited the natural expression of the effect. In this study, we propose a method of visualizing joint effect based on shader in order to construct welding training system. The results of this study can be applied to the welding training system to improve the weld training effect to provide the user with high-quality visualization.

본 논문은 광주과학기술원(GIST)에서 개발하고 있는 전남지역 '운주사'의 천불천탑 설화를 근간으로 한 반응형 가상 문화 체험 시스템(Responsive Multimedia System for virtual storytelling)의 햅틱 변형 상호작용에 관한 것이다. 기존의 디지털 문화재 체험 시스템은 사실적인 체험을 제공하기 위해 시각 및 청각 기술 개발에 많은 연구 및 노력이 이루어져왔다. 그러나 최근 인간의 인지 체계의 중요 요소인 촉감 상호작용의 중요성이 증대 됨에 따라, 본 논문에서는 가상 문화재 체험을 위한 햅틱 변형 알고리즘 및 상호작용 시스템을 개발하여 가상 불상을 만져보고 그 표면을 변형시키게 함으로써 몰입감을 증대하고 재미를 주는 시스템을 제공하였다. 아울러 체험의 몰입감 증대를 위해 본 시스템은 시/청각과 더불어 청각 효과를 가미하여 체험 시 발생되는 주변 환경의 소리(새, 물, 바람소리)를 제공하고, 기존의 문화체험 시스템과의 차별성을 위해 3 차원 입력장치를 이용하여 체험자가 직접 가상 불상을 변형시키면서 체험자 고유의 작품을 만들어낼 수 있는 상호작용을 제공한다. 따라서 제안된 햅틱 변형 상호작용 시스템은 체험자의 능동적 참여 및 흥미 유발을 통하여 문화 유산에 대한 교육적 효과 및 관심 증대에 기여할 수 있을 것이라 여겨진다.

In this paper, we apply the learning of the mobile robot insect augmented reality Digilog Book. In the era of electronic, book written in paper space just have moved to virtual reality space. The virtual reality, constraints spatial and physical, in the real world, it is a technique that enables to experience indirectly situation not experienced directly as user immersive experience type interface. Applied to the learning robot Digilog Book that allows the fusion of paper analog and digital content, using the augmented reality technology, to experience various interactions. Apply critical elements moving, three-dimensional images and animation to enrich the learning, for easier block assembly, designed to grasp more easily rank order between the blocks. Anywhere at any time, is capable of learning of the robot in Digilog Book to be executed by the mobile phone in particular.

Recently, with the development of virtual and augmented reality technology, metaverse is emerging as a new paradigm that will lead the next-generation internet era, and social and economic activities are spreading around the game, entertainment, music, and content industries. Moreover, as non-face-to-face conversion accelerated after the outbreak of COVID-19, lifestyles and industrial sites are becoming untact and further rapidly becoming a metaverse. In particular, the application of metaverse to the education field is attracting attention because realistic classes using real-time voice conversations using avatars, 3D objects, and 360-degree images can increase immersion and overcome the limitations of distance education. This study examines the concept of metaverse and examines that education using metaverse can be an alternative that can increase the efficiency of education in the non-face-to-face era. In particular, it shows that it is effective in language education and suggests an actual metaverse-based Korea language education program.

This study aimed to track changes in students' perception about schools over time, to analyze how participation in the Education Welfare Priority Support Project(hereafter "the Project") explains the changes, and to determine how the results of changes affect students' learning engagement, self-confidence, and peer relationship. Data were collected from 103 schools nation-wide(51 elementary and 52 middle schools) from 2015, 2016 and 2017 from 820, 911, and 837 students, respectively. The data were analyzed by applying a latent growth model with two stages: unconditional and conditional. The findings are that first, the perception about schools by the students who participated in the Project increased over time; and second, that the improvement of students' perception of schools has a positive influence on their learning engagement, self-confidence, and peer relationship. In the future, it was suggested that programs aimed at improving positive perception about schools should be provided to all students led by teachers, and a customized integrated support program should be arranged to students in need of intensive support by the educational welfare specialists.
