This work examines discourse on uses of computer technology and its transformation during the last thirty years effecting Korea landscape architecture. First, in the 1990s landscape architects begun to use computers as a new technology for landscape architecture, programming computer software utilities suitable for landscape research, planning, and design. The landscape architects, acting as computer programmers, tried to explore various techniques for landscape analysis and design with a piece of software, and various experts within the field of landscape architecture collaborated with each other. However, landscape architects mainly used computer technology as a tool as a substitute for hands-on cases. Since around the 2000s, the discourse on mapping and diagrammatic techniques as a visualization technique for landscaping processes have begun. Also, realistic representations for perspective drawings using graphic software have been increasingly important. The landscape architects, acting as graphic designers, focused on the specific visualization techniques for landscape planning and design. However, computer technology has been mainly used to produce realistic visuals aids for final presentations instead of creative exploration to generate landforms. Additionally, recent landscape architects have been using landscape performance modeling and parametric modeling for landform and landscape furniture design. The landscape architects as spatial designers are actively using computer modeling as creative form-generating tools during the design process.

Monolithic three-dimensional integrated chips (3D ICs) are an emerging technology that offers an integration density that is some orders of magnitude higher than the conventional through-silicon-via (TSV)-based 3D ICs. This is due to a sequential integration process that enables extremely small monolithic inter-tier vias (MIVs). For a monolithic 3D memory, we first explore the static random-access memory (SRAM) design. Next, for digital logic, we explore several design styles. The first is transistor-level, which is a design style unique to monolithic 3D ICs that are enabled by the ultra-high-density of MIVs. We also explore gate-level and block-level design styles, which are available for TSV-based 3D ICs. For each of these design styles, we present techniques to obtain the graphic database system (GDS) layouts, and perform a signoff-quality performance and power analysis. We also discuss various challenges facing monolithic 3D ICs, such as achieving 50% footprint reduction over two-dimensional (2D) ICs, routing congestion, power delivery network design, and thermal issues. Finally, we present design techniques to overcome these challenges.

Motion graphic is the recently emerged technique which extends the ways of expression in video industry. Currently, it is worldwide trends that the image design gets more attention in the field of movie, advertisement, exhibition, web, mobile, games and new media, etc. With the development of computer's new technologies, VFX methods for the visual content is dynamically changed. Such production methods combine the real scenary and CG(Computer Graphic) to compose realistic scenes, which cannot be pictured in the ways of ordinary filming. This methods overcome the difference between the real and virtual world, maximize the expressive ways in graphics and real space. Match moving is technique of accurate matching between real and virtual camera to provide realistic scene. In this paper we propose the novel technique for motion graphic image production. In this framework we utilize the match moving methods to get the movements of the real camera into 3D layer data.

The effective geometry processing IP architecture for mobile SoC that has real time 3D graphics acceleration performance in mobile information system is proposed. Base on the proposed IP architecture, we design the floating point arithmetic unit needed in geometry process and the floating point geometry processor supporting the 3D graphic international standard OpenGL-ES. The geometry processor is implemented by 160k gate area in a Xilinx-Vertex FPGA and we measure the performance of geometry processor using the actual 3D graphic data at 80MHz frequency environment The experiment result shows 1.5M polygons/sec processing performance. The power consumption is measured to 83.6mW at Hynix 0.25um CMOS@50MHz.

The influence of one sided striated surface roughness on load carrying capacity of a slider bearing is analyzed for very low clearance films. A Reynolds equation appropriate for slider bearing is derived and analyzed by the method of finite difference method. For a slider bearing with several simple roughness form, the pressure, load capacity and other parameters can be revealed and also this results can be stored in sequential data file. After all, their distribution can be displayed easily by using the CADG(Computer Aided Design and Graphics) program. Also exact solutions with this nemerical method are compared with those of the theory attributed to Tonder and White. The results reported here should find application in the computer peripherals where computer aided design and graphic package is needed.

This paper proposes an algorithm of CAD data extraction for the computer controlled marking system. In general, logo has been directly designed at the marking controller, but that is not an effective method because of the very limited working area. In this paper, for the data extraction we used a general PC and Auto CAD for logo design, and developed the software with GUI(Graphic User Interface) method. Then the data is transferred to the marking controller for marking on the object. With experimental result we showed the proposed algorithm to be very effective in the computer controlled marking system.

Today is a 'high concept' era in which consumers make sensible consumption that shares a sensible bond with a brand. Therefore, it is important to analyze consumers' aesthetic awareness; namely, fashion feeling in the fashion industry. This study conducted research into a fashion design planning process according to a fashion feeling focusing on computer graphics suited to the 21st century digital trend. First, the study classified a fashion feeling with eight senses including elegance, classic, modern, mannish, sporty, avant-garde, ethnic, and romantic feelings. Second, the study made an image map, color map, material map, and style map with Adobe Photoshop CS3 by dividing a fashion planning process with a computer graphics program. Also, the study made a flat illustration with Adobe Illustrator CS3. Third, the study proposed the image map, color map, material map, style map, fashion illustration and flat illustration in the design planning process under the theme of the aforementioned eight fashion feelings.

The act of design in landscape architecture consists of a concept within a designer's mind, technical representations, and finally, a process of construction. In the 4th Industrial Revolution, the design process is facing many changes due to the rapid development of computer technology and the IT ecosystem. Computer technology was initially developed for simple functions, such as mathematical calculation and graphic representation. However, after the spread of Personal Computers, starting with IBM and Macintosh, programming languages and hardware rapidly developed, algorithms and applications became specialized, and the purpose of using computers became very diverse. This study diagnoses issues concerning the functions and roles that new design methods, such as computational design, parametric design, and algorithmic design, can play in landscape architecture based on changes in the digital society. The study focused on the design methodology using parametric technology, which has recently received the most attention. First, the basis for discussion was developed by examining the main concepts and characteristics of parametric design in modern landscape architecture. Prior research on the use of parametric design in landscape architecture was analyzed, as were the case studies conducted by landscape design firms. As a result, it was confirmed that parametric design has not been sufficiently discussed in terms of the number and diversity of studies compared to other techniques investigated by landscape design firms. Finally, based on the discussion, the study examined specific cases and future possibilities of the parametric design in landscape architecture.
