사무실에 뱀이 나타났다. 종합건설사들은 이 뱀을 어떻게 처리할까? 모 회사는 상부에 보고부터 한다. 어떤 업체는 협력업체를 부른다. 또 어떤 회사는 작전회의부터 한다. 또 다른 업체는 전 직원이 모여 회의를 한다. 직원이 바로 잡는 회사도 있다. 각 업체별 정체성을 우스개 소리로 표현한 말이다. 직원이 바로 잡는 업체는 바로 현대건설이다. 현대건설은 '불도저'란 또 다른 별명이 있다. 6.25 전쟁의 폐허 위에서 국토의 핏줄인 도로를 닦고 끊어진 다리를 연결하고 건물을 세우는 등 아무 것도 없는 불모지에서 불도저처럼 건설산업을 이끌어 왔기 때문이다. 건설산업 발전을 견인한 현대건설이 올해로 창립 70주년을 맞았다. 이번 호에는 지난 2월 7일 상무로 승진한 현대건설 박성민 상무(건축사업본부 건축기술지원실 실장)를 만나 보았다.

본 논문에서는 드럼연주에 있어서 라이드 심벌 비트(ride cymbal beat)를 중심으로 현대 재즈리듬과 폴리리듬과의 연관성에 관하여 생각해 보고자 한다. 현대는 아주 다양한 장르의 음악들이 서로서로 영향을 주고받고 있기 때문에 다양한 음악을 수용하는 특징을 가지고 있는 재즈에서의 리듬은 어느 한 가지로 단순히 정의할 수 없다. 그러나 재즈의 전통적인 측면에서 볼 때 그 변화를 이야기 할 수 있는 리듬은 보편적인 재즈리듬이라 일컬어지는 스윙리듬(swing rhythm)이다. 이러한 스윙리듬은 현대의 폴리리듬을 이전보다 더 정교하게 연주하는 연주인들의 영향으로 말미암아 재즈의 역사 속에서 변화해 온 것과 다르게 좀 더 음표의 정의에 맞게 연주되는 경향이 생겼다. 이것은 어떤 면에서 전통적인 재즈리듬의 느낌, 혹은 개개인의 개성이 다소 사라지고 좀 더 기계화, 정형화되었다는 것을 의미한다.

This paper is a study on the 'primitivism' which is constantly being applied on modem and contemporary textile design as a aItanative expression of the serious environmental phenomena of materialism. Starting with the analyzation of the 'concept of primitivism' , this paper is to research the 'origin of primitivism' which was first recognized by the modem artists. Primitivism on modem textile design will be suggested through 'trend terms'. The purpose of this paper is to be a basic material source for the creative development in design as well as to be of help in development of theoretical the study on contemporary textile design.

지구온난화와 같은 환경적 문제점들로 인해 에너지 저감 및 고효율의 기술개발을 통한 탄소 저감이 주목을 받고 있다. 시대적 관심과 요구에 발맞춰 에너지 저감 효과가 있는 영구자석동기 전동기 등의 신기술을 철도차량에 적용하려는 연구가 활발히 진행되고 있다. PMSM을 철도차량에 적용하기 위해 추진제어장치는 인버터 한 대가 한 대의 전동기를 제어하는 1C1M 방식이어야 하며, 유지보수성과 안정성을 확보하기 위해 전동기와 인버터 사이를 전기적으로 분리해줄 수 있는 차단기가 필요하다. 또한 에너지 저감과 고효율을 달성하기 위해서 추진제어장치는 소형, 경량화 구조로 개발 되어야 한다.

The purpose of this research is to try to enrich human life by applying the convergence energy of humanities and science to modern poetry. "Communication and entertainment", as modern poetry with modernist aesthetics, must indulge people's lives, which is simply to live happy lives. Entertainment is especially crucial because it is a method through which people can lead humane and satisfactory lives. The prerequisites for achieving this are true liberty and happiness. If these two prerequisites derive from humanity's consciousness, "communication and entertainment" can be born from "convergence of information technology and modern poetry", as the author insisted.

For several decades, productivity in construction industry has been regressed and it is inevitable to improve productivity for major EPC players. One of challenges to achieve this goal is automatically extracting information from imaged drawings. Although computer vision technique has been advanced rapidly, it is still a problem to detect pipe lines in a drawing. Earlier works for line detection have problems that detected line elements be broken into small pieces and accuracy of detection is not enough for engineers. Thus, we adopted Contour and Hough Transform algorithm and reinforced these to improve detection results. First, Contour algorithm is used with Ramer Douglas Peucker algorithm(RDP). Weakness of contour algorithm is that some blank spaces are occasionally found in the middle of lines and RDP covers them around 17%. Second, HEC Hough Transform algorithm, we propose on this paper, is improved version of Hough Transform. It adopted iteration of Hough Transform and merged detected lines by conventional Hough Transform based on Euclidean Distance. As a result, performance of Our proposed method improved by 30% than previous.

Currently, a lot of researches about high risk test scenarios for autonomous vehicle and advanced driver assistance systems have been carried out to evaluate driving safety. This study proposes new type of test scenario that evaluate the driving safety for autonomous vehicle by reconstructing accident database of national automotive sampling system crashworthiness data system (NASS-CDS). NASS-CDS has a lot of detailed accident data in real fields, but there is no data of accurate velocity in accident moments. So in order to propose scenario generation method from accident database, we try to reconstruct accident moment from accident sketch diagram. At the same step, we propose an accident of occurrence frequency which is based on accident codes and road shapes. The reconstruction paths from accident database are integrated into evaluation of simulation environment. Our proposed methods and processor are applied to MILS (Model In the Loop Simulation) and VILS (Vehicle In the Loop Simulation) test environments. In this paper, a reasonable method of accident reconstruction typology for autonomous vehicle evaluation of feasibility is proposed.

Recently, use of composite materials has been increasing for body structures and chassis parts in the car industry because of weight reduction effect and excellent mechanical thermal characteristics. However, application of composite materials in brake system is very difficult because it is hard to obtain enough brake performance due to low heat storage capacity of the composite materials. In this paper, we will present new carbon ceramic composite disc with high flow characteristic. To obtain this characteristic, new vent structures were designed by using ARIZ method and substance-field model analysis. The flow effect of these vent structures on the brake performance was verified by pugh matrix and cooling test. The test results show improvement of cooling performance up to $30^{\circ}C$. Finally, These results will improve brake the reliability of the brake performance for the high performance vehicles and electric vehicles.
