소프트웨어 교육은 현대사회의 필수 교육으로서, 초등학교부터 교육을 접할 수 있도록 교육정책 및 지원 등이 강화되고 있는 실정이다. 그러나 코로나 팬데믹 이후 소프트웨어 교육 체험 활동 중단에 따른 비대면 교육의 한계로 교육 취약 계층과 영재 교육과의 격차가 심화되었다는 우려의 목소리가 크기에 격차 해소에 대한 대책이 필요하다는 의견과, 지역별 취약 계층에 대한 계획이 없는 교육 제도의 변화를 요구하고 있다. 따라서 에듀테크와 통합된 교육 콘텐츠의 중요성이 부각되고 있다. 본 논문에서는 큐브 형태의 모델링이 가능한 3D 모델링 프로그램인 타다크래프트를 기반으로 교육 소외 계층도 손쉽게 접근할 수 있는 교육 커리큘럼을 제안한다. 3D 모델링을 구현함으로써, 학습자들은 학습에 대한 성과와 흥미를 획득할 수 있고, 공간 확장 능력을 배양할 수 있을 것으로 기대된다.

3D SCAN enables easy human body measurement via a digital method in the process of film costume production which used to be done manually. Software-oriented computer graphic, which integrates 3D SCAN data in the process of manual film costume production, can induce quick and diverse design outcomes. While, 3D PRINT, which integrates computer graphic data in the process of manual film costume production, can automate the process of special costume production using a digital method. Integration of 3D Scan + Computer Graphic + 3D Print using integrated platforms for tailored costume production as developed in this study allows significant reduction of costume production period and costs. It also allows efficient integration of costume production outcomes in various industries related with OSMU contents in particular. In other words, using it, we can create a new business market that integrates multiple areas of film content, drama content and game content.

Various researches on 3D silhouette extraction have been performed in the area of computer graphic. This paper presents a new method for internal pattern extraction by using an arbitrary region silhouette control technique. The proposed method was tested by using 3D data of stone pagodas. The results show that the proposed method particularly improves the performance of internal pattern extraction.

This paper demonstrates the in-house development of the subsystem C&DH in a D-SAT satellite project of Astronautic Technology (M) Sdn. Bhd. (ATSB). D-SAT is a non-imaging satellite. It will carry a dosimeter as the payload for scientific objectives. Since one of the D-SAT project establishment intended objectives is to demonstrate the research and development skill of the ATSB engineers on the satellite system building, most of the subsystems of the D-SAT are developed in-house including the C&DH subsystem. C&DH subsystem plays an important role for managing data handling tasks and general operation of the satellite system. The C&DH development includes the research and study on the hardware and software design, the design of both the hardware and software, the development of the software system, the integration between the software and the hardware system and the implementation of the subsystem into the satellite system. This program allows ATSB to accomplish the engineers with expertise not only in the C&DH subsystem but other subsystems too besides developing knowledge in the management of a space project that covers not only on the technical issues but issues relating to the economic, political and legal issues.

On-machine automatic measuring software from 3-D solid modeler is generally applied to assess the functional performance of a final produce for computer numerical control (CNC) machine. Automatic measuring software may also be performed on individual components of CNC machine in which some functional aspect of the component must be examined and cannot be implicity determined by means of a mechanical inspection. The manufacturing specialist, combined with the appropriate software simulation, can not only create the commands to drive the virtual measuring but also can check for mistakes by viewing the computer graphics simulation of the tool cutting sequence.

In this study, we organize and explain various ways to construct 3D models in the 2D plane using Geogebra, mathematical education software that enables us to visualize dynamically the interaction between algebra and geometry. In these ways, we construct three unit vectors for 3 dimensions at a point on the Cartesian coordinates, on the basis of which we can build up the 3D models by putting together basic mathematical objects like points, lines or planes. We can apply the ways of constructing the 3 dimensions on the Cartesian coordinates to modeling of various structures in the real world, and have chances to translate, rotate, zoom, and even animate the structures by means of slider, one of the very important functions in Geogebra features. This study suggests that the visualizing and dynamic features of Geogebra help for sure to make understood and maximize learning effectiveness on mechanical modeling or the 3D CAD.

The cooperation between universities and IT industry in producing IT manpower of quality is urgently called for to create the effective labor pool of supply and finally balance its supply and demand. Korean Government launched a program where industrial demand-driven curriculums are developed and applied to universities. This paper proposes a design technique of meta-modeling demand-driven curriculums and courses, based on the 3D software space and the software development process. This technique is proven to result in extensibility, flexibility and quality improvement in software design. Therefore, we expect that the proposed technique makes curriculums and courses possible to be continuously improved in many aspects.

Hardware, software, networking to Digital Contents. Most of the Small and medium IT Enterprise strategy shift of R & D system. In 2001, IT Small and medium size manufacture occupied 3.8% of Gross Domestic Product. IT industry R&D Program and Excellent Information Technology R&D Program support rate $54{\sim}60%$ of computer, software and contents for Information Technology R&D, when the Technology of R&D input to market need to development for about 3 years. Most of the Small and medium IT Enterprise strategy priority find out from computer, software and contents.

Today, the growth of software industry leads to e quantitative expansion of software package products. Due to this rapid increase of software package products, qualify certification has been required fur software products which users select. Unlike the quality certification of industrial products, the history of software product certification has not been so long. For this reason, software quality evaluation and certification methods have not matured yet. When certifying software products, one of most important factors is the systematic generation of evaluation sets. The evaluation sets include checklists with metrics, and criteria for the software quality certification according to the classification of software product type. This paper presents a metamodel for the systematic generation and maintenance of the evaluation sets. Then, we construct prototype level evaluation sets to show the validity of the metamodel.

It is possible to implement high quality system which coincided with embedded system purchaser's requirements by quality test. The concrete quality test system applicable within our country for embedded software was not constructed yet. Recently, various embedded systems are developed, but they have many problems such as recall by defect. In this paper, we developed evaluation modules and quality test fables which can implement duality test based on ISO/IEC 12119 for embedded software evaluation.
