The aim of this paper is to study the concept of s-topological d-algebras which is a d-algebra supplied with a certain type of topology that makes the binary operation defined on it d-topologically continuous. This concept is a generalization of the concept of topological d-algebra. We obtain several properties of s-topological d-algebras.

게임 개발사의 경영진이나 개발자들을 통해 유니티 엔진을 다룰 수 있는 프로그래머에 대한 수요가 무척 많다는 것을 확인할 수 있다. 유니티의 사용 환경으로 과거 PC 온라인 게임을 중심으로 게임 개발이 이루어졌을 때에 비해 개발사의 수도 많아졌고, 한 개발사에서 동시에 만드는 게임의 수도 크게 증가하고 있다. 본 논문에서는 Unity 3D 엔진을 심층 분석하여 게임개발 교육현장에서의 유용성을 검토하였다. 본 연구는 게임 앱 설계 관련 프로젝트의 수행이나 교육용 게임 개발의 학습을 위한 유니티의 현주소를 조명하는 데 있다.

본 논문에서는 초등학생을 위한 교육용 3D 골드버그 장치 애플리케이션을 개발하였다. 골드버그 장치는 창의력 증진을 위해 많이 제작한다. 하지만 골드버그 장치를 제작하기 위해서는 넓은 장소와 많은 도구가 필요해서 비용이 부담된다. 그래서 애플리케이션으로 개발하여 부담을 줄이고 실제로 골드버그 장치를 제작하는 것처럼 하기 위해 Unity 3D 엔진을 이용하여 3D와 물리법칙을 적용했다. 개발한 애플리케이션은 교육 프로그램에서 활용하여 초등학생의 창의성 증진, 물리법칙 이해, 공학적 설계능력 향상, 수학적 사고력 향상에 도움이 될 수 있다고 생각한다.

Sinsu Island in Korea National Marine Park is suitable for geological learning and geotourism as various geological structures, geological activities, and fossils can be observed. In this study, eight geosites were developed by analyzing 2015 revision science curriculum. The 3D panoramic geological virtual field trips were developed according to the three-step outdoor learning model. The 3D panoramic geological virtual field trips, which consist of 8 classes, are composed of cooperative learning by group, enabling autonomous inquiry activities. It is designed to realize convergence education that can learn not only geology but also creativity and humanity through nodular Limestones, exfoliation, salt weathering, perforated shell holes, sedimentary structures and environments, dinosaurs habitats, and volcanic activity. Five experts revised and supplemented the Delphi analysis method to verify the validity of the development purpose and direction. The satisfaction with the geological field for Sinsu Island course was 4.52, indicating that the overall satisfaction with the field course was high. By reflecting on the opinions of each student and reinforcing safety education, we completed the 3D panoramic geological virtual field trips for Sinsu Island. The 3D panoramic geological virtual field trips in Sinsu Island in Korea National Marine Park will be a good example of geology learning tourism where you can make memories and enjoy while studying geology.

The purpose of this study is to draw a distinction between general computer graphics courses and game development ones and to find out making various improvements in game graphics courses. In addition to general hand-drawing skills and computer graphics technology which are essential for the students who major in game graphics; however, the special classes should be required for them to comprehend the work process of game development and to produce the game graphics data. This necessity of the discriminative education is going to be an identification of game development department. Although loading game data onto a game engine and finding out the solution to problems of data is one of the excellent settlement for educating game graphics students, it is not possible to purchase the commercial game engine such as Quake or Lithtech and to analyze the commercial program libraries. For this reason, this research presents the replacement of commercial game engine with VRML97 for the academic purpose and shows what effect upon education will be. It is expected that the VRML97 can be a substitute of the game engine for the effectiveness of game graphics education with more active study and verification of game fields.

Today, one of the most important reasons that 3D software becomes a core part of the essential tools in the video contents field like the movies, animation, CF, motion graphic, games and etc. is that they can save budget of contents makings and can produce better effects than conventional methods like miniature, matt painting, extra mobilization and etc. and can save time and have the merit that they are not limited in space. In this paper, I analyzed IK(Inverse kinematics) system characteristics for the efficient education of 3D character animation particularly most used of 3D applications which is now supposed to be nearly necessary elements in game, animation, movie and contents. And by analyzing merits and demerits of each tool on Bone, Character studio and Character Animation Toolkit, systems which are most used practically in the various Inverse kinematics tools, I showed the result of analyses about the fact that educating which of the above three Inverse Kinematics tools is helpful and beneficial for the students for the efficient education in the university where should teach much in the limited time

This study aims to develop qualification criteria for training and establishing an expert pool of 3D printing operation experts and 3D printing development specialists in the emerging 3D printing industry. We investigate the domestic and international 3D printing industry, as well as 3D printing- related training institutions and quantity of test examinees. Utilizing competency analysis, this study examines the competencies and educational content of both 3D printing operation expert as well as 3D printing development specialists. In addition, a survey was conducted on the issue of institutionalization of qualification criteria for 3D printing operation expert and 3D printer development specialists. This study further proposes evaluation methods for qualification criteria for both 3D printing operation expert and 3D printer development specialists based on simulations of both written and performance tests. Based on the findings, this study proposes instructional program outlines as well as comprehensive guidelines for training and qualification processes for 3D printing operation expert and 3D printer development specialists.
