For successful surgery-first approach, accurate prediction of skeletal and dental changes following orthognathic surgery is essential. With recent development of digital technology using computer-aided design/computer-aided manufacturing (CAD/CAM) technology, attempts to provide more predictable orthodontic/orthognathic treatment have been made through 3D virtual surgery and digital tooth setup. A clinical protocol for the surgery-first orthognathic approach using virtual surgery is proposed. A case of skeletal Class III patient with facial asymmetry treated by the surgery-first approach using digital setup and virtual surgery is presented. Advantages and limitations of applying CAD/CAM technology to orthognathic surgery are discussed.

디지털트윈은 현실에서의 상황을 가상의 세계에 만들어 놓고 시뮬레이션 하여 결과를 예측하는 기술이다. 디지털트윈은 제조업에서 뿐 아니라 다양한 산업에서나 사회적 문제를 해결할 수 있는 기술로 주목받고 있다. 따라서 디지털트윈을 이용하여 현실상의 도시 개발과 가상의 도시개발을 쌍둥이로 진행하여 다양한 테스트를 하는 역할을 수행해 볼 수 있다. 이러한 디지털 트윈 시스템이 제대로 동작하고 있는 지를 검증하기 위해서는 이를 위한 테스팅 기술이 필요하며 특히 가상의 소프트웨어로 동작하는 것이 주를 이르는 특성을 반영한 소프트웨어 테스팅 기술이 필요하다. 이에 본 논문에서는 디지털 트윈 시스템에서의 소프트웨어 테스팅 기술 동향에 대해 살펴보고자 한다.

This study is intended to set the concept of becoming meaning of digital space through digital technology and to study the influence of digital space on becoming of real space through derived keyword. The results of this study are summarized as follows. First, the digital concept is created in the process that the virtual space is changed into the real space with a priority given to form, space and time. Digital expression concept and image concept the structural becoming, and idea concept and creative concept creates the time becoming. Second, the concept of digital becoming exposes a physical visibility through the digital's virtual image, and non-space spatiality through the space simulation. It also continuously reveals a consecutive time and non-consecutive time through a statable progress, incremental progress, and dynamic progress. Third, as the influence of digital on becoming of real space, the digital visibly not only expresses the new and difficult becoming problem through conceptual virtuality, but also can review the real space's space concept with virtuality in the digital non-area. Digital's durability expresses the new space's existence by physically combining with the existing space through the virtual form creation.

Recently, Modeling and Simulation, which have been received attention in various in dustries such as national defence, eduction and entertainment, have been researched, and related applications have been developed actively. Especially, it is focused on the to chnology of a virtual reality and a virtual simulation which represents the implementation technology for the simulation education related to the e-Learning industry. However, a solution is needed to fulfill the lack of technology and research about standardize d data elements which could be applied to virtual simulation technologies in common. Therefore, this article suggests the virtual simulation data elements to increase the educational effect of a virtual simulation and interoperability of data among LMS through reference to korean and international standards and the result of related area analysis. In other words, this article aims to define the expression of data element and to propose the guideline elements in the virtual simulation scope.

Since the past, an attempt of figuration which is for movement, time and force has existed constantly. A process of representative from expressed on the movement, time and force creates events, and the process through the events expresses the idea of a simulacre. Furthermore, Architectural works for potentiality to give a demonstration are in common with hybrid characteristics, and have lasting creation of flux architecture. Ignoring the gravity of the floating figuration, so it appears unrealistic hyperphysical virtual space that easily could make the life of creation. For this reason, the form generation based on the digital design method is expressed the important method. In conclusion, actualizing the virtual is the suitable way for 'devenir architecture' based upon the Deleuze Guattari's idea of 'simulacre' and creating the from generation on the contemporary digital architecture design in a similar way.

메타버스 내 가상세계는 가상적으로 확장된 물리적 현실과 물리적으로 영구화된 가상공간이 융합(convergence)되어 나타난 문명의 장이다. 컴퓨터 인터페이스의 기능과 역할이 확대 및 발전되고 가상에 대한 패러다임이 전환됨에 따라, 가상은 현실을 복제하는 단계를 넘어서서 상상력을 통해 독자적인 '가상 세계(Virtual World)'를 구현하기에 이른다. 가상세계는 크게 환상성, 유희성, 게임성이 강조된 '유희적가상세계(The Ludic Virtual World)'와 실재성, 효율성, 네트워크성이 강조된 '사회적 가상세계(The Social Virtual Reality)'로 분류할 수 있다. 북미의 경우 사회적 가상세계가 중시되는 반면, 유독 한국에서는 허구적 세계관에 입각한 유희적 가상세계가 각광받고 있다. 한국 가상세계의 발전방향은 반현실에 대한 욕망과 허구적 상상력을 극대화할 수 있는 장으로서 유희적 가상세계에 놓여있다.

In order to realize the virtual prototyping (VP) of digital products, it is important to provide the people involved in product development with the appropriate visualization and interaction of the products, and the vivid simulation of user interface (UI) behaviors in an interactive 3D virtual environment. In this paper, we propose an approach to web-based 3D virtual experience using Unity and Leap Motion. We adopt Unity as an implementation platform which easily and rapidly implements the visualization of the products and the design and simulation of their UI behaviors, and allows remote users to get an easy access to the virtual environment. Additionally, we combine Leap Motion with Unity to embody natural and immersive interaction using the user's hand gesture. Based on the proposed approach, we have developed a testbed system for web-based 3D virtual experience and applied it for the design evaluation of various digital products. Button selection test was done to investigate the quality of the interaction using Leap Motion, and a preliminary user study was also performed to show the usefulness of the proposed approach.
