  • We can easily buy network system for high performance micro-processor, progress computer architecture is caused of high bandwidth and low delay time. Coupling PC-based commodity technology with distributed computing methodologies provides an important advance in the development of single-user dedicated systems. Lately Network is joined PC or workstation by computers of high performance and low cost. Than it make intensive that Cluster system is resembled supercomputer. Unix, Linux, BSD, NT(Windows series) can use Cluster system OS(operating system). I'm chosen linux gain low cost, high performance and open technical documentation. This paper is benchmark performance of Beowulf clustering by UltraSPARC-1K(64bit-RISC processor). Benchmark tools use MPI(Message Passing Interface) and NetPIPE. Beowulf is a class of experimental parallel workstations developed to evaluate and characterize the design space of this new operating point in price-performance.

  • This research investigates the design process of free-form architecture to understand the design strategy and changing factors during the development phase and the cause for them. It is aimed to foresee the changing factors from the design process and to reduce design changes. It analyzes the design changes of free-form architecture based on projects with finalized documentation or under construction in South Korea. Many free-form shapes of the free-form architectures have to be adjusted to rigid-form in order to satisfy function and be economical to build. The research finds three patterns in design changes. First, from the factors for design changes: function, constructability, design, program add/subtract, efficiency, circulation; Function and Constructability are the higher factors compared with the rest. The two are the design changes suitable for actual usage and cost savings. Second, each project has different predominant factors for design changes as the degree of free-form is different. Contrary to initial expectation, the greater the degrees of free-form of the competition scheme, the higher the rate of Function among the factors for design changes. Constructability is higher when the degree of the free-form is less than others. It means that the lower the degree of the free-form, the more properly planned the space of the building is. Last, Constructability of free-form architecture is considered during the earlier design phase than definite-form, one by which the design changes by comparing 'Before fixed Space Program' (BSP) and 'After fixed Space Program' (ASP) design changes. The research would be helpful as a reference for setting up competition guidelines to reduce trial and error during the design process.

  • Nature/Landscape is surrounding space in which we make living. It is considerably comprehensive tenn. but on the other hand, the site can be existence, experience, and certain circumstance with boundaries. Based on these places, through contemporary art criticism, this study is to contemplate how art since 1960s, especially, site-specific art in three-dimensional space intervene in the environment. Artists of today put more value on the process and act of art making founded on the external, and they tend to create the characteristic of site or to indicate linguistic documentation. Moreover, a large-scale tendency of contemporary sculpture and 'occupation of specific site' seems to accede spatial conception from architecture. The core that recognizes these artworks is with body, that is to say, the space in which Self becomes the subject by changing the structure of the work while moving around it. In particular, 'Site-specific Art (in situ)' sometimes determines the form inward or outward It also relates directly on viewer's five senses by looking, hearing, and feeling, touching, and interacting. For example, in Richard Serra's , the viewer who moves around the work has the role to manipulate the movement of the work by perception. Works of In situ and works that planned for specific site suggest 'occupation of site' as of the function of the work These sites are ideal and special as well as being independent. Ultimately, it seems that the creative process of contemporary artists is to carry those intended form on the structure of perception. Furthermore, law of nature such as entropy, and acceptance of contingency helped organic structure of artwork become more abundant. For Robert Smithson, entropy suggests of reaching to a state of equilibriumin which everything is the same. This means that any core is justifiable and any rank is possible. Because the world without a core is a labyrinth of boundless exploration.

  • 빠르게 변하는 정보화 사회에서 방대한 양의 문서 정보를 전자 문서로 만들고 관리하는 것은 필수적이다. 이러한 전자 문서를 표현하는 데 있어서 사용하는 문서 내에 포함된 모든 정보를 손실 없이 저장하고 관리하는데 적합한 언어가 전자 문서의 표준인 XML이다. 본 논문에서는 문서의 변경이 발생한 경우에 문서 전체가 아닌 변경이 발생한 내용만 버전을 부여하고 저장함으로써 저장 공간을 절약하였다. 그리고 문서의 변경 내용이 일정한 크기 이하이면 JOIN 연산을 생략할 수 있도록 시스템을 설계함으로써 JOIN 연산으로 인한 시스템의 성능 저하를 줄여 효율적인 XML 문서 저장과 빠른 검색 및 버전 관리가 가능한 방안을 제시하고, 이를 적용한 문서 저장 관리 시스템을 구현하였다.

  • Architectural Drawing has been settled down the very effective means of exchanging their architectural ideas and data on the construction process. However, it was not easy to conserve the original drawings, which aims had been accomplished, at the same time, building was built. The same phenomena were occurred in our traditional architectural construction project, especially before pre-modern age. And do not understand soundly building documentation accepted by craftsmen in the period of earliest Chosun dynasty and how to present their idea and information of architectural as means of sketches and drawings. So, this paper aimed to clarify the drawing occurrence and the development steps of their rendering, representation methodology in the construction process in Sannungdogam-Uuigue, which were the construction documents of government based on the royal family's tomb and building projects in the late Chosun Dynasty. There are three development stages of architectural space representation, pre-drawing stage, drawing occurring stage and drawing settlement stage, They had been adapted unique drawing presentation method which were drawn by artisan, so called Doseol(圖說)and Painter Hwawon(畵員) The results are 1. In the Pre-drawing stage, they had been used the systematic explanation method of character 2. Do not have the evidence of adapting drawing before 17th centry, it was originated in early 17's century started with Onga(甕家). Onga's Drawing was drawn very elementary skill, and became development, settlement and standardization of their drawing representation around 19th century 3. The drawing presented by client's recognition view of space and building, integrated data within a sheet of drawing with practical and hierarchy and using graphic and description.

  • The characteristics of aerodynamic drag for Transonic Vehicle in Evacuated Tube was investigated using computational fluid dynamics. At first, parametric study on the system was performed according to the Mach number of the vehicle's speed ($Mach_v$), evacuated pressure of the tube ($Pre_t$), and blockage ratio (BR) between the vehicle and tube via axisymmetric flow analysis; the $Mach_v$ ranged from 0.3 to 1.0. The $Pre_t$ was 100, 1,000 and 10,000 Pa and the BR was 0.1, 0.2, and 0.4. In the calculations, the aerodynamic drag of the vehicle was larger when the BR and the pressure became larger. Concerning the $Mach_v$, the drag coefficient ($C_d$) became the maximum when the $Mach_v$ was near the Kantrowitz limit and decreased, which showed the typical transonic flow pattern. Then, three dimensional flow analysis was performed by changing the $Mach_v$ from 0.3 to 1.0 and setting the BR and the $Pre_t$ as 0.34 and 100 Pa, respectively by referring the Hyperloop Alpha documentation. From the calculations, the $C_d$ from three dimensional flow simulations were somewhat larger than those of axisymmetric ones because of the eccentricity of the vehicle inside the tube. However, the pattern of $C_d$ according to the $Mach_v$ was compatible with that of axisymmetric ones.
