Many traditional architectures of Korea were lost due to fire accident caused by various reasons. It has been reported that faulty electric facility is the major cause of fire. Protecting and preserving the traditional architectures under current management system and electric facility regulation are difficult. Therefore establishing early stage fire extinguishment process and management system is urgent as well as eliminating the cause of fire.

Studies on the principle of traditional moulding techniques of architecture or structure are very important in the point of the work could accomplish succession to modern design. As an attempt of these work, this study tried to examine traditional moulding techniques applied in planes of ancient architecture and structure closely. The major findings of this study are summarized as follows; It was verified that planes of ancient Korean architectures and structures analyzed in this study was moulded by its multiple partitions with the six or eight partitions of circumference as the fundamental form. The well unearthed in kyong-bok palace recently was moulded by a concentric circle assumed form of 4 circle which was extended with equal interval and divided into multiple of 8 partition of circumference. Chon-duk-jung in chang-duk palace also was moulded by a concentric circle assumed form of 3 circle extended with equal interval, but circle were divide by 6 partitions. It was also found that 6$^{\circ}$§8 partitions of circumference(or its multiple partition) was applied to not only above structures but also the moulding planes of ancient architecture, and as a results, figures revealed in architectures analyzed is classified into three classes. And, this study analyzed arrangements of two temples. As a results, it is discovered that the Grid used in moulding planes of each building fixed the arrangement of buildings. Therefore, moulding by equal partition of circumference decided the form of each building and the relation of element at the same time.

전통건축물은 인류가 살아오면서 만들어 온 수많은 문화유산 중 하나로서 인류의 과학기술과 역사적인 사실들을 투영하고 있는 소중한 문화유산인 동시에 중요한 기록문화유산이다. 전통건축물은 건축물 자체로도 중요할 뿐만 아니라 그로부터 파생되는 그림, 도면, 단행본 등과 같은 여러 매체로도 표현된다는 특징을 가지고 있다. 이러한 관계들을 표현하고 전통건축물과 그에 관련한 기록물을 효율적으로 관리 보존 활용하기 위하여, 본 연구에서는 국내 외 문화유산 관련 메타데이터 현황을 알아보고 문제점들을 분석하여 이를 바탕으로 FRBR모형에서 제시하는 1집단 4계층의 논리구조 기반의 전통건축물 메타데이터 스키마를 제시하였다.

멀티플레이어 온라인 게임을 위한 주요 구조는 전형적으로 클라이언트-서버, 멀티 서버, P2P(peer-to-peer) 구조 등이 있다. P2P 구조는 본질적인 분산과 협동 특성으로 인하여 구축 비용이 저렴하며 플레이어들 간에 직접 통신을 수행함으로써 빠른 응답시간과 높은 규모조정성을 가질 수 있다. 그러나 P2P 구조는 여러 가지 어려움이 존재한다. 플레이어들 간에 게임을 분산시키므로 제어 유지가 어렵고 특정 플레이어의 고의적인 부정행위에 취약해지는 경향도 있다. 또한 갱신과정의 충돌 현상이 여러 사이트에서 발생될 수 있기 때문에 P2P 시스템에서 일관성 제어를 제공하는 것도 더욱 어렵다. 비일관성을 회피 또는 정정하기 위하여 대부분의 멀티플레이어 게임은 객체에 대한 갱신이 주 사본에 먼저 수행되는 주 사본 기법을 사용한다. 본 논문은 멀티플레이어 온라인 게임을 위한 P2P 구조에서 각 객체에 대한 일관성을 제공하며 갱신 결과의 전송 메카니즘이 존재하는 주 사본 모델과 이에 대한 성능 분석 결과를 기술한다.

Face Detection is one of the most important aspects of image processing, it considers a time-consuming problem in real-time applications such as surveillance systems, face recognition systems, attendance system and many. At present, commodity hardware is getting more and more heterogeneity in terms of architectures such as GPU and MIC co-processors. Utilizing those co-processors along with the existing traditional CPUs gives the algorithm a better chance to make use of both architectures to achieve faster implementations. This paper presents a hybrid implementation of the face detection based on the local binary pattern (LBP) algorithm that is deployed on both traditional CPU and MIC co-processor to enhance the speed of the LBP algorithm. The experimental results show that the proposed implementation achieved improvement in speed by 3X when compared to a single architecture individually.

Recently, the power consumption of integrated circuits has been attracting increasing attention. Many techniques have been studied to improve the power efficiency of digital signal processing units such as fast Fourier transform (FFT) processors, which are popularly employed in both traditional research fields, such as satellite communications, and thriving consumer electronics, such as wireless communications. This paper presents solutions based on parallel architectures for high throughput and power efficient FFT cores. Different combinations of hybrid low-power techniques are exploited to reduce power consumption, such as multiplierless units which replace the complex multipliers in FFTs, low-power commutators based on an advanced interconnection, and parallel-pipelined architectures. A number of FFT cores are implemented and evaluated for their power/area performance. The results show that up to 38% and 55% power savings can be achieved by the proposed pipelined FFTs and parallel-pipelined FFTs respectively, compared to the conventional pipelined FFT processor architectures.

This paper is to evaluate the application potentials of data mining in the areas of Supply Chain Management (SCM) and to suggest the architectures of Decision Support Systems (DSS) that support data mining activities. We first briefly introduce data mining and review the recent literatures on SCM and then evaluate data mining applications to SCM in three aspects: marketing, operations management and information systems. By analyzing the cases about pricing models in distribution channels, demand forecasting and quality control, it is shown that artificial intelligence techniques such as artificial neural networks, case-based reasoning and expert systems, combined with traditional analysis models, effectively mine the useful knowledge from the large volume of SCM data. Agent-based information system is addressed as an important architecture that enables the pursuit of global optimization of SCM through communication and information sharing among supply chain constituents without loss of their characteristics and independence. We expect that the suggested architectures of intelligent DSS provide the basis in developing information systems for SCM to improve the quality of organizational decisions.
