As a proto-modernist work the Amsterdam Exchange has been regarded as a specimen of Structural Rationalist's architecture. Because of its ma]or steel structure, use of geometry, and reminiscence of Gothic the designer of the building was labeled by Kenneth Frampton as one of the apostles of Viollet le Duc. The architect was Hendrick Petrus Berlage. Contrary to above Nicolaus Pevsner claimed that Berlage's architectural discourse was 'Anti-Rational' because of its anachronistic formal language, Expressionism. In terms of structure Berlage's idea is rational, whilst formally 'Anti-Rational'. These polarised view points were due to the legacies of Modern Architecture that was controled by hegemonic figures in terms not only of practical field but of historiography. The hegemonic figures wanted to see Berlage as what they wanted to see. With this idea, this paper is one of endeavours to collect fragmented history in the early modern architecture. The Amsterdam Exchange has a long term story until the opening. Without understanding the story we have to withhold an evaluation of Berlage's architecture.

단독주택을 8-10가구의 다세대 주택으로 용도를 바꾸는 '지분 쪼개기' 때문에 최근 서울을 비롯한 수도권 곳곳에서 다세대 주택 신축 붐이 일고 있다. 서울시가 무분별한 지분 쪼개기를 막기 위해 가구당 전용 면적 $60m^2$ 미만 주택은 입주권을 주지 않고 돈으로 청산하는 방식으로 규제하겠다는 방침을 밝혔지만, 현장에서는 다세대나 빌라 신축 공사가 더욱 활발하게 진행되고 있다. 게다가 조례를 개정하는 7월 전까지 건축 허가를 받으면 면적에 상관없이 입주권을 받을 수 있다는 점을 노린 막판 투기가 기승을 부리고 있어 논란이 일고 있다.

본 연구에서는 자동차의 스테빌라이저 링크를 모델로 하여 로워암과 연결되는 곳에 고정을 하고 모멘트를 가한다. Model 1, 2 및 3는 각각 길이 조정형, 일반형 및 일체형들이다. 이 모델들은 CATIA와 ANSYS로 설계 및 강도해석을 통한 융합 기술을 수행함으로서 연구된다. Model 3의 최대 등가응력이 가장 작음으로서 Model 3가 3개의 모델들 중 가장 큰 하중을 견딜 수 있다. 피로 해석으로서는 Model 3가 응력 상태의 빈도수가 일어나는 구간이 가장 작음으로서 세가지 모델 중 가장 안정적이다. 그 다음으로 Model 1, Model 2 순으로 안정적임으로서 응력 상태의 빈도로서 구간 수가 커지고 불안정성이 더 커진다. 그리고 디자인 면에서의 융합 기술로의 접목도 가능하여 미적인 감각을 나타낼 수 있다.

차량 선회 시 조종안정성과 주행 승차감을 향상시키기 위하여 능동적으로 차체의 롤(roll)을 줄이기 위한 연구가 진행되고 있다. 전동식 능동 롤 제어(ARC) 시스템은 전후 스테빌라이저바 중앙에 위치한 전동 모터 방식의 구동기에 의해 차량의 차체 롤을 제어한다. 본 연구에서는 이러한 전동식 ARC 시스템의 제어 성능 및 차량 동역학적 특성을 평가하고 검증하기 위한 해석, 벤치 시험, 실차 시험의 3단계 절차와 방법을 제안하였다. ARC 제어로직의 성능 및 타당성 평가를 위한 Matlab/Simulink와 CarSim 간의 연동-해석 방법을 제안하였고, ARC 구동기 및 시스템의 성능을 평가하기 위한 벤치 시험 방법과 실차 시험 방법을 제안하였다.

The vehicle stabilizer link is one of the suspension components that reduces the bumping and rolling during vehicle driving. However, this stabilizer link could be a source of the abnormal noises when its free gaps have higher than normal values. Therefore, the current study aims at investigating the quantitative relationships between the abnormal noises and free gaps of the vehicle stabilizer links, as well as the length of time that the vehicle stabilizer links could be used without generating abnormal noises. In this study, the abnormal noises were measured based on the magnitude of the stabilizer link vibration, while the free gaps were quantified through the force-displacement curves of the stabilizer links. Harsh durability tests were also conducted in order to quantify the operating cycles of the stabilizer links before generating the abnormal noises, along with the concomitant measurements of the free gaps. The current results showed that the abnormal noises of the stabilizer links were detected when its free gaps were larger than 0.12 mm. However, the free gaps of the stabilizer links, which are bigger than 0.1 mm, produced the abnormal noises at 1.5 million cycles under harsh durability test conditions. A parametric study in the future that would reflect the different shapes and sizes of the stabilizer links for diverse vehicles could determine more generalized relationships between the abnormal noises and free gaps of the vehicle stabilizer links.

This study is purposed to understand the usage of the color and the material pattern in detail and to apply for interior architecture. Many documents have prescribed the color and the pattern at random. While the usage of the color and the materials was ignored rather than architectural form, the importance of the color and the materials stands out in modern interior space. The villa, the weekend home of the Savoye family, was built between 1928 and 1931. Particularly, the villa Savoye was focused for this study. Le Corbusier viewed case pieces for storage and wall partition for division as architecture, and he units furniture and architecture by developing partition that could be painted either the wall color to become part of the wall or in contrasting colors to stand out as wall partition. He loved white and lie believed in using it for interiors, but noted that it should also be balanced with a wall related polychromy. Color became an integral part of white structure of the villa savoye that was raised on stilt with an exterior wall at the base painted green as a visual connection with the lawn. Color was used architecturally in the interior as well, with white walls interrupted by planes of pink, blue and red ocher and it gives the space an unexpected playfulness with tile color of the finishing materials. the various usage of the color and material patterns constitute an element of great architectural richness. They have a unique principle based on emotional order and make the man move to another space and experience the spacial connection.

A System for reducing vehicle body roll by active control is developed. The stabilizer bar with hydraulic rotary actuator produces anti-roll moment which suppresses roll tendency. This reduction of roll improves the driving safety as well as the ride comfort. Vehicle test data shows considerable reduction of roll angle during steady-state turning. Also improvement of ride comfort is achieved by making the actuator freely rotatable, i.e. by connecting all chambers of actuator in normal driving conditions. A control algorithm using steering wheel angle and vehicle speed signal as input valve is applied. It is compared with signal of the G-sensor.

Cross-flow fans are widely used in various applications, due to their large capacity of mass flow and size compactness. The flow field of the cross-flow fan is, however, complex and has many design parameters. Thus, the general design guide has not been sufficiently established yet and the design strategies of cross-flow fans have been mostly based on experiments. In the present study, the performance and their two-dimensional flow characteristics are numerically analyzed by using the STAR-CD(commercial computational fluid dynamics code). The simulation is done by varying the several design parameters such as the impeller blade shapes and the gap between the stabilizer and impeller. The computational results are compared with the experimental data at the fan outlet region. Finally, some helpful guides for the optimum design of cross-flow fans are proposed.
