Storytelling approach is the way to formulate and solve problems using stories. Story is a means to understand and react everyday life that can be regarded as multi-dimensional problems. The approach becomes popular in various fields in conjunction with digital technology. In particular, it is used to solve problems in relation to whole context. In design, storytelling approach is used to clarify design constraints. It can be used to clarify and communicate thoughts for design artifacts, and to understand how the artifacts might be used in particular circumstances. In particular, the approach is useful to use under uncertain circumstances. In architecture, storytelling approach can be used in the area of design generation, design critique and capturing design knowledge. In design generation, it can be used to describe and formulate design experiences rather than simple designing artifacts. The approach formalizes design based on stories of user experiences. Digital technology such as virtual reality can be used to experience designed spaces for design modifications. In design critique area, it can be used to fill uncertain facts for historical buildings as welt as different from present status. Such stories can be used to build digital modeling and used to open criticism. Stories can be used to formalize knowledge in architectural domain as a form of implicit knowledge for certain projects. In architecture, it often is required to design types of environment never experienced before as well as to accomodate fast changing technologies. Storytelling methodology can be used as a method to cope with uncertainty and complexity in design requirements along with accumulating design knowledge.

We describe the development of a prototype multi-channel electrical impedance tomography (EIT) system. The EIT system can be equipped with either a single-ended current source or a balanced current source. Each current source can inject current between any chosen pair of electrodes. In order to reduce the data acquisition time, we implemented multiple digital voltmeters simultaneously acquiring and demodulating voltage signals. Each voltmeter measures a differential voltage between a fixed pair of adjacent electrodes. All voltmeters are configured in a radially symmetric architecture to optimize the routing of wires and minimize cross-talks. To maximize the signal-to-noise ratio, we implemented techniques such as digital waveform generation, Howland current pump circuit with a generalized impedance converter, digital phase-sensitive demodulation, tri-axial cables with both grounded and driven shields, and others. The performance of the EIT system was evaluated in terms of common-mode rejection ratio, signal-to-noise ratio, and reciprocity error. Future design of a more innovative EIT system including battery operation, miniaturization, and wireless techniques is suggested.

본 논문은 디지털 오디오 코덱에 효율적으로 적용 가능한 새로운 역 양자화 테이블 보간 알고리즘과 알고리즘에 특화된 DSP(Digital Signal Processor) 명령어 및 하드웨어 구조를 제안한다. 비선형 역 양자화 알고리즘은 대표적으로 MPEG-1 Layer-3와 MPEG-2/4 AAC(Advanced Audio Coding)에서 사용되며, 제안하는 명령어는 비선형 역 양자화에 최적화 되어 있다. 제안하는 알고리즘은 연산의 복잡도를 최소화하여 구현 시전체 연산량을 줄일 수 있으며, 제안된 알고리즘은 타 알고리즘에 비해 우수한 평균 오차값을 나타낸다. 제안하는 명령어 및 하드웨어 구조는 기존의 알고리즘과 비교하여 연산 과정에서 사용되는 명령어 수를 20% 정도 줄일 수 있으며, 역 양자화의 계산 부하를 효율적으로 줄일 수 있다. 제안한 알고리즘은 일반 상용 DSPEE 구현이 가능하다.

This paper describes the design of a multistandard video encoder. The proposed encoder accepts conventional NTSC/PAL video signals, It also processes he PAL-plus video signal which is now popular in Europe. The encoder consists of five major building functions which are letter-box converter, color space converter, digital filters, color modulator and timing generator. In order to support multistandard video signals, a programmable systolic architecture is adopted in designing various digital filters. Interpolation digital filters are also used to enhance signal-to-noise ratio of encoded video signals. The input to the encoder can be either YCbCr signal or RGB signal. The outputs re luminance(Y), chrominance(C), and composite video baseband(Y+C) signals. The architecture of the encoder is defined by using Matlab program and is modelled by using Veriflog-HDL language. The overall operation is verified by using various video signals, such as color bar patterns, ramp signals, and so on. The encoder contains 42K gates and is implemented by using 0.6um CMOS process.

The purpose of this study is to develop design quality indicator for improvement of public architecture in Korea. The spatial scope of the study which sees limited at 'domestic public buildings'. The study contents scope is to develop design quality indicator to use design phase and evaluation of 'public buildings'. For this design quality indicator, we have analysed various domestic and international institutions associated with architecture design. And, design indicator for the possibility of application in public buildings were extracted. Through this work design quality indicator specific and objective was drawn. The results of this study 8 category were drawn 'Public', 'Harmony', 'Impact', 'Access', 'Landscape', 'Use', 'Sustainable', 'Technology'. Also, 29 Design quality Indicator were suggested. Finally, this study was developed by utilizing Design Quality Indicator can be utilized in the design phase, the evaluation process should be developed.

The purpose of the study is to analyze how to document survey and repair data on wooden architecture culture assets. Documentation was analyzed in comparison to digital developments from the past to the present. Although the accuracy of survey equipment has been improved by digital development, survey drawing has not changed. For example, a 3D Scanner, survey equipment, was introduced but is being used for conversion into 2D data. Data provided by the drawing included in the survey and repair reports were not accumulated. As it stands, it is inaccessible and disorganized. Data generated from the survey, repair, and maintenance has to be consistent. A BIM system was proposed to integrate information on wooden architecture cultural assets.

The purpose of this study is to arrange the design elements and methods for sustainable community. After made the concept of sustainable community clear in the contemporary architecture and urban design, this study examines rural ecovillage, urban demonstration project, co-housing, new urbanism and urban village, and ecological township as the application modes of sustainable community. Through the cases of the application mode, the design elements for sustainable community were summarized as the followings: the symbiosis system with the nature, permaculture and edible landscape, identity, the technology for saving of resources and energy, the traffic system for the reduction of private motor use, mixed use development, and the housing with diversity. And the design methods for sustainable community were summarized as the followings: strategic planning, visioning, community action planning, workshops and charrette, environmental evaluation, and participation techniques.

As we know usually architecture of Korea landscape painting inside, pavilion(Jung-ja) and many-storied building(Ru-gak) have painted mainly. But besides general building that home, mountain fortress wall, temple, royal palace was expressed by a real view landscape painting. The main purpose of this research is to enhance the basis that can understand well tradition architecture by korea landscape painting. To achieve this goal, Even if it is same kind of building, a lot of differences become by material of roof, position of building, expenditure of building. Division of inside and outside is precious data that can know life physiognomy of general peoples. In Structural side, Expression of fabrication and value as data that can know composition and arrangement of plane are important.
