This paper is for investigation and analysis of how a visual studio is widely used by domestic broadcasting companies and broadcasting companies' production environment. The history of a visual studio goes back to start of computer graphic. A visual studio is a way to produce a program using graphic sets created by a computer rather than actual setting, and it allows to express beyond limitations of actual studio settings and various imagery visual effects can be created by a computer. A visual studio can create 3-dimensional graphic and these graphics can be inter-locked with actual camera images to make visual spaces for various programs. These flows are aiming to achieve very natural image which is hard to distinguish it is artificially created rather than just to produce programs with simple image synthesis, and this paper analyzes the producing changes of domestic broadcasting visual studios as well as its usage and suggests the idealist direction for developing the production.

This thesis is the analysis of programing cases by which each broadcasting station generates visual studio. When the broadcasting stations make programs, they overcome the visual limitation of expression by using visual studio other than the real set. This trend is the progress toward more realistic and delicate image by almost perfect image expression, not just broadcasting production by mere synthesis operation. It suggests the development direction toward visual studio production by analyzing production cases using domestic visual studio.

The high-tech computer technology developments have greatly affected the area of design education. Starting from the mid 80s, innovations in visual presentation methods have heightened with 2D computer graphic programs, CAD & 3D modeling, and Rapid Prototype that allows dimensional generation. The specialty and quality in design studio education have advanced due to the development in presentation methods such as Power Point and Keynote. But there are many problems with the current method of presenting the visual outcome in a data format using beam projectors, which is a vertical presenting method compared to the old studio study method of conducting discussions and reviews based on the substantial outcome. The essence of studio study that allows for comparisons and analysis by horizontally opening up the various work outcomes is being offset. Also the requirement for manual idea sketching work that plays an important role in the initial design phase continuing to decrease due to the digital working process dependence and cumbersome procedures in the presentation. In order to resolve this problem, the CALM system (Class Applied LCD Modular System) has been developed that replaces the method of attaching the sketches or renderings on the wall with a digital multi-display system. In a nutshell, individuals will upload the outcomes online and display them on the CALM system studio that is composed of 32 LCD (Columns: 4 $\times$ Rows: 8) monitors that are 19 inches in size so that various personnel can openly study the design outcomes. Also the central 42 inch PDP monitor that offers touch pad capability allows each design outcome to be described and examined by expanding. The concept phase of this development process has elevated to the production of an operating prototype that is being reviewed of its practicality. It is considered that the development of this system will decrease the extreme tendency of depending on digital operation but achieve revitalization of a more realistic and opened studio study environment compared to the individual consulting method of the old study approach.

This article takes the talk show "Beast Town" as an example to introduce the overall technical solution, technical difficulties and countermeasures for the combination of cartoon virtual characters and virtual studio technology, providing reference and experience for the multi-scenario application of digital humans. Compared with the live broadcast that combines reality and reality, we have further upgraded our virtual production technology and digital human-driven technology, adopted industry-leading real-time virtual production technology and monocular camera driving technology, and launched a virtual cartoon character talk show - "Beast Town" to achieve real Perfectly combined with virtuality, it further enhances program immersion and audio-visual experience, and expands infinite boundaries for virtual manufacturing. In the talk show, motion capture shooting technology is used for final picture synthesis. The virtual scene needs to present dynamic effects, and at the same time realize the driving of the digital human and the movement with the push, pull and pan of the overall picture. This puts forward very high requirements for multi-party data synchronization, real-time driving of digital people, and synthetic picture rendering. We focus on issues such as virtual and real data docking and monocular camera motion capture effects. We combine camera outward tracking, multi-scene picture perspective, multi-machine rendering and other solutions to effectively solve picture linkage and rendering quality problems in a deeply immersive space environment. , presenting users with visual effects of linkage between digital people and live guests.

In this paper, we developed an e-loaming contents for C programming language using Linux and open source software, not using commercial integrated development tool like Microsoft's Visual Studio. In most programming language courses, students study or practice the programming language by editing source code compiling and running the executable code by commercial software like Visual Studio which installed on each PC. This way of learning has some difficulties in total cost of purchasing software and using other PCs which donot have proper software installed. To overcome this situation and enable loaming anywhere, with any device, at anytime, we propose a way of utilizing Linux and open source software in Web-based learning environment. In this environment students can input their source code on the form of broweser and get the result instantly from the server.

In this paper, we presents visual effect(water, fire, smoke) simulation and interaction system for TV virtual studio. TV virtual studio seamlessly synthesizes CG background and a live performer standing on a TV green studio. Previous virtual studios focus on the registration of CG background and a performer in real world. In contrast to the previous systems, we can afford to make new types of TV scenes more easily by simulating interactive visual effects according to a performer. This requires the extraction of the performer motion to be transformed 3D vector field and simulate fluids by applying the vector field to Navier Stokes equation. To add realism to water VFX simulation and interaction, we also simulate the dynamic behavior of splashing fluids on the water surface. To provide real-time recording of TV programs, real-time VFX simulation and interaction is presented through a GPU programming. Experimental results show this system can be used practically for realizing water, fire, smoke VFX simulation and the dynamic behavior simulation of fish flocks inside ocean.

The aim of this thesis is to evaluate visual arts policy during Kookmin government period(1998-2002). In the beginning, many artists had expected president Kim Dae Jung to enlarge arts support But the evaluation of them was very negative because the government was only interested in the development of cultural industry. First, I analysed the government expenditure in the visual arts. Department of Culture and Tourism took the responsibility of visual arts policy. The budget of arts and culture increased to 1 % of total government expenditure in this period. But the main factor was the increasement of cultural industry and tourism expenditure. The budget of visual arts in 2002 was only 6,600million won. Second, I analysed visual arts support programs. (1) The government introduced studio programs for the first time. For 5 years, 2 national studios and 23 public studios were established. (2) The number of art museum was increased to 62. (3) It introduced alternative space support program and supported 200million won annually. (4) Percent for art scheme reduced from 1% to 0.7% of total construction cost, but still 27 public sculpture gardens were built. (5) Business support for visual arts reduced because of IMF. (6) Also arts market froze and many commercial galleries were closed. (7) In order to revitalize region through arts and to promote international exchange of culture, Gwangju Biennale was created. Third, I analysed Arts Plan 2002. It had a radical limitation because it was established in the last year of Kookmin government period. Also it showed special favors to some arts organizations. In general, I think that positive outcomes are the introductions of the studio program and the alternative space support program. Especially alternative space support program enforced the diversity of visual arts, and encouraged creative young artists. But policy of arts market failed because of IMF and visual artists had to go through rough times.
