Digital virtual manufacturing is a technology that aims for the rapid development of products and the verification of production-process in ways that are more efficient by integrating digital models within the entire manufacturing process. These digital models utilize various information technologies, such as 3D CAD and simulations. Mixed reality, which represents graphical objects for only needed parts against real scene, can bring a more enriched sense of reality to an existing virtual manufacturing system that is in a pure virtual environment, and it can reduce the time and money needed for modeling the environment. This paper suggests a method for planning virtual factory layouts based on mixed reality using legacy datathat are already constructed in the real field. To do this, we developed the method to acquire simulation data from legacy data and process this acquired data for visualization based on mixed reality. And then we construct display system based on mixed reality, which can simulate virtual factory layout with processed data. Developed system can reduce errors related with factory layout by verifying the location and application of equipments in advance before arrangement of real ones at the practical job site.

Recently, BIM has become mandatory in the construction field, research on various use cases is increasing. In particular, when virtual reality technology, one of the core technologies of the 4th industrial revolution, and BIM are combined, it can be used in various fields such as preliminary design review and construction simulation. Until now, however, virtual reality grafting technology is only used as a simple prototype or as a model house. Also, it is difficult to activate virtual construction because it is expensive to produce high-quality virtual reality contents. Therefore, in this paper, in order to increase the utilization and quality of the virtual construction field, a study was conducted to shorten the material mapping time, which takes a lot of time when producing virtual reality contents using BIM. To this end, object properties were assigned to enable material mapping in the BIM model, and materials most used in the construction field were configured, and automated material function development and final tests were conducted that automatically map properties and materials. For the test, 10 models were used and the test was repeated three times, and the productivity improvement of about 50.16% was finally achieved. In the future, we plan to conduct research on physical data weight reduction based on the advanced material mapping automation function and the large-capacity BIM model.

해외로 부터 대량의 방위장비 조달이라는 발상은 일본의 주식인 쌀의 수입 이상으로 약간은 당돌하게 느껴지는 사람도 있을 것이다. 그러나 일본으로서는 군사침략을 받는다고 가상한 최악의 사태에, 필요하고도 충분한 방위장비품이 자연스럽게 확보될수 있는 방안을 확립해두는 조치가 바람직하다. 그 구체적이고 실현가능한 처방전으로서 방위장비품을 해외에서 생산하는 구상은 그 의의를 평가받아야 한다. 또한 방위장비품을 국제조달함으로써 우호국간에 강력한 연대관계가 빚어지는 점에도 착안하여야 한다.

Nowadays, one of the major technical issues in manufacturing is how to implement an virtual plant as an well-designed, integrated environment for sharing information and engineering collaboration among diverse engineering activities. The systematic approaches to make a virtual plant based on a 3-dimensional CAD, cell and line simulation, database and internet technologies are proposed in this paper. To do that, measuring and 3D CAD modeling technologies of many equipments, facilities and structures of the building are developed, effective management of information including models and related files in WWW environment is implemented, and precise simulations of unit cell and whole structured plant are performed. For the beginning of implementing a Virtual Automotive Plant, the Virtual Plant for the Body Shop of a Korean automotive company is constructed and implemented. Using this Virtual Plant, shorten car development time and cost saving are possible.

Due to the current COVID-19 pandemic, companies and institutions are introducing virtual desktop technology, one of the logical network separation technologies, to establish a safe working environment in a situation where remote work is provided. With the introduction of virtual desktop technology, companies and institutions can operate the network separation environment more safely and effectively, and can access the business network quickly and safely to increase work efficiency and productivity. However, when introducing virtual desktop technology, there is a cost problem of high-spec server, storage, and license, and it is necessary to supplement in terms of operation and management. As a countermeasure to this, companies and institutions are shifting to cloud computing-based technology, virtual desktop service (DaaS, Desktop as a Service). However, in the virtual desktop service, which is a cloud computing-based technology, the shared responsibility model is responsible for user access control and data security. In this paper, based on the shared responsibility model in the virtual desktop service environment, we propose a cloud-based hardware security module (Cloud HSM) and edge-DRM proxy as an improvement method for user access control and data security.

CALS체계에서는 한 제품의 주문으로부터 생산과 사후 관리에 이르는 전수명주기를 통합관리해야하므로 화상과 음성을 포함한 멀티미디어 정보를 교환할 수 있어야 한다. 더욱이 기존의 산업사회에서는 순차적 공정에 따른 생산방식을 적용해 왔으나, 향후 미래사회에서는 민첩한 지능형 가상기업만이 생산경쟁력을 갖출 수 있는 생산형태의 변화가 예상되어 경쟁력있는 기업모형의 변화가 뒤따를 것이며, 기업경쟁력의 우선순위는 한 품목의 생산에 소요되는 시간과 비용, 그리고 소비자의 성향에 맞는 우수한 품질이 고려된 동시공정 체제를 갖추는 것이 매우 중요한 과제로 대두될 것이다. 이러한 CALS의 성공적인 구현을 위한 기본적인 주요 요소기술은 기업업무처리 변화에 다른 업무공정의 표준화, 통합데이타베이스를 이용한 동시공정의 설계, 그리고 기업내.외의 모든 거래를 디지털 방식으로 송.수신하는 전자상거래로 대별할 수 있으며, 그중 동시공정은 기술적으로 매우 중요한 부분이라 할 수 있다. 이를 위해서는 기업내의 부서 상호간은 물론 원자재의 수급에 참여하거나 생산에 공동으로 참여하는 모든 기업들 간에 상호 정보교환이 동시에 발생할 수 있어야 하며, 이러한 다양한 정보공유자로부터 얻어지는 모든 자료를 통합관리하여 의사결정자가 신속하고 정확한 판단을 할수 있도록 지원체계를 만들어야한다. 본 연구는 이러한 CALS체계에서 동시공정 작업이 신속하게 성공적으로 수행될 수 있도록 분산된 정보들에 대한 신속한 의사결정을 지원하는 관리자에 대한 방안을 제시하고자 한다.
