Spoken dialog system development includes many laborious and inefficient tasks. Since there are many components such as speech recognizer, language understanding, dialog management and knowledge management in a spoken dialog system, a developer should take an effort to edit corpus and train each model separately. To reduce a cost for editting corpus and training each models, we need more systematic and efficent working environment. For the working environment, we propose DialogStudio as an spoken dialog system workbench.

본 논문에서 제안하는 파일 보안 기능은 암호알고리즘을 이용하여 윈도우 운영체제에서 파일을 안전하게 저장함으로써 허락되지 않은 사용자의 접근을 제한하도록 한다. 암호화하여 저장된 파일은 복호화 알고리즘으로 복호화해서 파일데이터를 읽게 된다. 이러한 기능은 사용자들이 편리하게 사용할 수 있도록 사용자 인터페이스를 설계하여 프로그램으로 구현한다. 보안 기능으로 구현된 파일 암호화 및 복호화 프로그램을 구동시키고 정상적으로 동작하는지의 여부를 실험하게 된다. 또한 복호화시 암호화 할 때의 설정과 설정이 틀 릴 경우 복호화가 되는지의 여부도 실험한다. 이러한 기능을 편리하게 사용할 수 있도록 Visual Studio 환경을 이용하여 UI(User Interface) 기능을 설계한다.

현재 RISCV-VP 시뮬레이션 프로그램은 Linux 환경으로만 존재하며, Windows 환경에서 동작하는 프로그램은 존재하고 있지 않다. 그래서 Linux 환경으로 개발된 RISC-VP(Virtual Platform)를 Windows 환경에서도 사용할 수 있게 Visual Studio 를 사용하여 구축하였다. 또한, Windows VS 환경의 RISCV-VP 프로그램을 통해 머신 러닝 시뮬레이션이 가능하도록 개발 환경을 구축하였다. 이 논문은 위에 설명한 각각의 개발환경 구축에 필요한 구성 방법을 제공한다.

Can art really change the way people understand and interact with nature in order to reduce the possibility that ecological disasters will continue to expand due to failure to correct human actions that damage the global environment? What is the artistic methodology to realize environmental justice and sustainability of life on Earth? This paper seeks to find answers to these questions. Finding ways to look at, feel, understand, and act for the global environment, that is, the process of considering the way of orientation toward the global environment will lead to critical thinking of the history in which human centered behaviors treated nature as a resource for exploitation rather than a source of life. Therefore, this paper pays attention to the ecological art of The Harrison Studio, which is called the 'pioneer of the environmental art movement'. In the main body, The Harrison Studio's major projects are analyzed to find ecological implications and aesthetic strategies. In particular, their dialogical methodologies are demonstrated in detail. To this end, the significance of various collaborative practices of The Harrison Studio is explained. The Harrison Studio contributed to expanding the scope of practical experience and understanding of the value of eological art. They have the power to look back on the direction of ecological consciousness by constantly producing mutually connected and overlapping epistemic dimensions without being limited to any uniform rules of exchange.

Collaborative systems allow users, who may be far removed from each other geographically, to do collaborative work such as 3D animation, computer game, and industrial design in a single virtual space. This paper describes our experience to develop a collaborative system framework that aims at expanding the some functions of a stand-alone visual modeling tool, called 3D Studio Max, into those of the distributed collaborative working environments. The paper mainly deals with design and implementation of a 3D shared-object Plug-In with respect to the 3D Studio Max Plug-In Software Development Kit in the distributed collaborative system developed by the authors. There are two major functions of the proposed scheme; one is to write 3D object-information to the shared memory after extracting it from the 3D Studio Max, the other is to create 3D objects after retrieving them from the shared memory. Also, the proposed scheme provides a simple way of storing 3D objects that have variable size, by means of shared memory which located in between the collaborative system clients and 3D studio Max. One of the remarkable virtures of the Plug-In is to reduce a considerable amount of shared object data which in consequence can mitigate the network overhead. This can be achieved by the fact that the system is able to extract a minimum amount of 3D objects that are required to transmit. Also, using the proposed scheme, user can facilitate 3D Studio Max into distributed collaborative working environments. This, in consequence give many benefits such as saving time as well as eliminating space constraints in the course of 3D modeling when we are under industrial design process.

This study analyzed the volumes generated by deep learning and atlas-based automatic segmentation methods, as well as the Dice similarity coefficient and 95% Hausdorff distance, according to the conditions of conduction voltage and conduction current in computed tomography for lung radiotherapy. The first result, the volumes generated by the atlas-based smart segmentation method showed the smallest volume change as a function of the change in tube voltage and tube current, while Aview RT ACS and OncoStudio using deep learning showed smaller volumes at tube currents lower than 100 mA. The second result, the Dice similarity coefficient, showed that Aview RT ACS was 2% higher than OncoStuido, and the 95% Hausdorff distance results also showed that Aview RT ACS analyzed an average of 0.2-0.5% higher than OncoStudio. However, the standard deviation of the respective results for tube current and tube voltage is lower for OncoStudio, which suggests that the results are consistent across volume variations. Therefore, caution should be exercised when using deep learning-based automatic segmentation programs at low perfusion voltages and low perfusion currents in CT imaging conditions for lung radiotherapy, and similar results were obtained with conventional atlas-based automatic segmentation programs at certain perfusion voltages and perfusion currents.

This paper introduces an experimental design studio that explores the optimal use of current digital technologies in order to employ Building Information Modeling at the early phase of design process. Based upon the outcomes from the aforementioned studio, the paper discusses the integrated design strategies for BIM in the design process. In this paper, BIM is proposed as a design tool that increases an overal design productivity more effectively and efficiently compared to BIM as a construction tool with encouraging a design communication among different partakers in the design process.

MPEG-4 표준은 초기에는 낮은 비트율의 영상 통신을 지원하였으나, 표준화 작업이 진행 되면서 스튜디오 프로파일(Studio Profile)과 같이 높은 비트율의 고화질 영상의 압축 전송을 포함하고 있다. 본 논문에서는 현재까지 진행된 MPEG-4 스튜디오 프로파일의 표준화 진행 상황을 살펴보고, 그 성능을 개선할 수 있는 방향을 제안한다.
