Space in the past had characteristics of place which are required for specific behavior to be done as we recognized it easily. However, for space in modern times, the purpose, forms and behavior space has, have changed as tools comprising the space have changed. 'Virtual space' which has been a conversation topic recently is unspecific and changeable space whose forms and geological location are not defined clearly. In addition, behaviors caused by this virtual space in combination with real space are taking place. The nature of Flash Mob which is one of the typical behaviors which take place starting from virtual space to be connected with real space, is that it is intangible game culture whose forms and behaviors are not fixed, and it is not limited to a specific place. Besides, Flash Mob is characteristic of representing game culture in modern society, and its nature can be summarized as temporariness, non-placeness, anonymity, double-sidedness and so forth. Since events generally take place in every place when man is involved in space, it's possible to generally think events derived from interpersonal relationships between man and man. We are to study spatial characteristics of Flash Mob by analyzing features and cases of the Flash Mob by means of them.

The remote operation of the Advanced Spent Fuel Conditioning Process (ACP) is analyzed by using the 3D graphic simulation tools. Since the spent nuclear fuel, which is a high radioactive material, is processed in the ACP, the ACP equipment is operated in intense radiation fields as well as in a high temperature. Thus, the equipment is operated in a remote manner and should be designed with consideration for the remote handling and maintenance. Also suitable remote handling technology needs to be developed along with the design of the process concepts. For this we developed a graphic simulator, which provides the capability of verifying the remote operability of the ACP without the fabrication of the process equipment. In other words, by applying virtual reality to the remote maintenance operation, a remote operation task can be simulated in the graphic simulator, not in the real environment. The graphic simulator will substantially reduce the cost of the development of the remote handling and maintenance procedure as well as the process equipment, while at the same time developing a remote maintenance concept that is more reliable, easier to implement, and easier to understand.

본 연구는 상황에 맞게 활용할 수 있는 회의 환경을 제공할 뿐 아니라 다른 단계의 회의를 제시하는 프로토타입 그룹웨어 환경(prototype groupware environment)을 개발하는데 그 목적이 있다. 또한 분산회의의 전체적인 수명주기를 지원하기 위해 사용될 수 있는 몇몇 구성요소들을 기술하고 있다. 이 시스템의 설계는 회의(meeting)가 3단계 즉, 예비 회의, 회의 활동, 그리고 회의 이후로 구성되어 있다는 전제에 기초하고 있다. 각 단계별 회의들은 개별적이고 각각 다른 종류의 도구들과 규칙들을 필요로 한다. 이러한 각 단계들을지원하기 위한 프로토타입은 여섯 가지 요소로 구성되어 있다. 전자우편은 회의 참가자들간의 커뮤니케이션을 지원하기 위한 도구이다. 회의 게시판은 참가자들의 명부를 조직하거나통지하는데 사용되고, 참가자들은 일정관리를 통해 분산회의를 추적해서 확인한다. 실제 회의는 참가자들이 의제를 통해 회의진행 절차를 확인하고, 참가자들과 그룹웨어 도구들을 갖춘 실제 가상회의실(virtual meeting room)에서 열린다. 마지막으로 주요 회의 사건은 회의록을 통해 기록된다.

Nowadays, one of the major technical issues in manufacturing is to create an environment to promote collaboration among diverse engineering activities. Collaborative engineering is an innovative approach integrating widely distributed engineering activities through promoting information sharing and actual collaboration. It requires close interactions among developers, suppliers and customers, and consideration of entire product life cycle from concept to disposal. A carefully-designed operating system is crucial for successful collaboration of many different activities in a Networked Virtual Manufacturing System(NVMS). High extensibility, flexibility and efficiency ale the key characteristics requested of an operating system to handle the complexity of the NVMSs. In this paper, we propose a model of the operating system for collaborative engineering using concurrent quasi-procedural method(QPM). QPM is a goal-driven data management technique for distributed and parallel computing environments. It is to be applied to the evaluation of activities to be executed, validities of input data, execution path of activities for a needed output, and expected to greatly improve the productivity of operations by preventing redundant evaluations. Collaboration among many different engineering activities in NVMSs is to be performed by the network of agents that encapsulate the capabilities of both users and their tools.

In other words, by applying virtual reality to the remote maintenance operation, a remote operation task can be simulated in a computer, not in a real environment. In this way the graphic simulator can substantially reduce the design cost of the remote operation process and the equipment. Also it can provide new operation concept that is more reliable, easier to implement, and easier to understand.

본 논문에서는 전자공학 초보자가 교육용 로봇의 제작과정을 온라인상에서 효과적으로 학습할 수 있는 콘텐츠를 설계하고 구현하였다. 제작한 콘텐츠에서는 가상의 실습실을 플래쉬 애니메이션으로 현실감 있게 제작하여 학습자가 마우스를 이용하여 부품을 조립하는 과정을 가상적으로 체험할 수 있도록 하였다. 또한 로봇 제작 단계 이전에 전자 기초 이론, 부품, 공구등에 대한 학습 과정을 이해하기 쉬운 용어 및 재미있는 예를 들어 설명하여 초보자를 배려하였다. 이상에서와 같이 본 논문에서 제안한 교육용 로봇 개발 콘텐츠는 이론적인 내용뿐만 아니라, 멀티미디어를 이용한 가상의 실습실을 통해서 현실감 있는 실습이 가능하기 때문에 로봇을 제작하고자하는 초보 학습자에게 유용한 콘텐츠가 될 것으로 생각된다.

Purpose: This study started with the question of how to use Virtual Reality (VR) contents as a part of the non-face-to-face education tool that has recently attracted attention. Methods: In this paper, the use of VR contents as an educational tool is explained as a process of 'new media access dimension'. The question was explored on why Virtual Reality (or Augmented Reality) contents are not used as educational tools in the educational field. Results: As a result, the lack of 'material access' such as devices and infrastructure affects 'motivational access' approach stage, which is the previous stage. Again, it has a negative effect on literacy, which is 'skill access' approach stage. As it was found that it was not circulating to the level of "motive-material-skill-usage", it was discussed that it was taking a different step from the past adoption process of ICT and smart media. Conclusion: Based on this, it is believed that immersive content will contribute to arousing interest that can be applied and spread in the educational field, and it is also thought that it will be possible to derive academic interest in the educational effect according to the characteristics of immersive content such as VR.

Various lean design and construction methods such as target value design, pull planning, value stream mapping have successfully transformed the commercial building construction industry into achieving improved productivity, higher design and construction quality, and meeting the target values of construction projects. Considering the significant advantages of lean, the accelerated dissemination and adoption of lean methods and tools for construction is highly desirable. Currently, the lean design and construction body of knowledge is imparted primarily through publications and conferences. However, one of the most effective ways to impart this soft knowledge is through getting students and trainees involved in hands-on participatory games, which can quickly help them truly understand the concept and apply it to real-world problems. The COVID-19 Pandemic has raised an urgent need of developing virtual games that can be played simultaneously from various locations over the Internet, but these virtual games should be as effective as in-person games. This research develops an online 3D simulation game for Target Value Design that is as effective as in-person games or possibly better in terms of knowledge capture and retention and enjoyable environment and experience. The virtual game is tested on volunteers using feedback from pre-and post- simulation surveys to evaluate its efficacy.
