EuroNCAP(European New Car Assessment Program) announced recently a modified testing protocol for side impact assessment using the EUROSID-2 dummy instead of the EUROSID-l dummy. The EUROSID-2 dummy is identical in many parts with the EUROSID-1 dummy but shows different behavior in experiments. Hence, the development of a model for the ES-2 dummy is of great interest for the automotive engineers working in the field of safety. This paper shows a technique of improving occupant injury performance when using an EUROSID-2 dummy.

The study investigates the performance of the reinforced concrete frame with the steel plate slit damper. The test was carried out to investigate the structural behavior between the reinforced concrete bare frame and the reinforced concrete frame with the steel plate slit damper. The test results showed that the energy absorption capacity of the damped-frame was several times larger than that of the bare frame. For the damage by the input energy is concentrated on the steel plate slit damper, the ductilities of the former structure were increased and the damaged frame can be reused after exchange the steel plate slit damper.

Floor vibration has been one of the major problems in residential buildings. Complaints on the floor vibration problem will be growing according to the demands and trends toward the higher environmental performance of buildings. This paper is aimed at investigating the vibrational performance of floor with bored opening structures to footfall loading induced by a human. For that purpose, mock-up tests were carried out in relation with isolating materials incorporated in floor with bored opening structures and the evaluations of vibrational serviceability were performed. The results show that, floor with bored opening structures have much higher vibration amplitudes in time domain than those of bare floor structure due to the vibrational components of higher frequency range over first natural frequency.

유사한 파일을 찾아내는 알고리즘 중에는 고정길이 청킹 알고리즘(Fixed Length Chunking Algorithm)이 널리 사용되고 있다. 고정길이 청킹 알고리즘은 파일을 일정한 크기로 잘라서 각각의 해시를 구하는 알고리즘이며, 파일의 일정 부분이 변형되어도 어느 정도의 유사도(Similarity)를 구할 수가 있다. 고정길이 알고리즘은 매우 짧은 시간에 파일들의 유사도를 어느 정도 판별할 수 있다는 장점이 있지만, 파일 내용에 삽입이나 삭제같은 변형이 일어나면, 변형된 부분부터는 모든 해시 값이 바뀌는 문제가 있다. 본 논문에서는 고정길이 알고리즘을 보완한 삼중 고정길이 알고리즘을 제안한다. 제안하는 방식은 고정 길이 방식보다 정확도가 높고 롤링해시 기법보다는 더 빠르게 수행되는 특성을 보인다. FLC(Fixed Length Chunking) algorithm is widely used in file similarity search algorithms. FLC algorithm divides a file into fixed size chunk and it calculates hash values for each chunk. This algorithm can find duplicated blocks of a file even though there is some modification on a file. FLC provides fast file similarity search, however, it cannot find duplicated region of blocks in a file when there is file modification. in this paper, we propose the triple fixed length hashing scheme that shows high accuracy for similarity detection compared to FLC and achieves very fast performance compared to Rolling hash scheme.

The management environmental change of the construction company is quick and new construction marketing is being extended. Accordingly, Business Process Management is demanded for the effectiveness and a profitability augmentation of the business operation. The justification of business process management introduction of the construction company is proved by existing literature. Because of business process management introduction, the strategic management model for the construction company propose. Change motive for a construction company is investigated. SWOT to change motive is analyzed.

Recently the interest of the process management is increasing. Many researchers have studied about how to applicate process management in the company. But this study, At the first, Researched the past theory flow of the process. Second, we analyze a case study of the construction companies that introduced the process management. Then we present to illustrate how the process management model is able to change and to advance the effective direction.

본 논문에서는 확장 가능한 파일 전송 시스템을 제안하고 있으며 기존의 FTP와 중복 제거 기술을 지원한다. 기존의 전통적인 파일 전송 프로토콜을 지원하고 고정 분할 중복 제거 및 가변 분할 중복 제거 기술을 이용한 파일 전송을 지원하는 것을 핵심으로 한다 본 기법의 주요 아이디어는 빠른 시간 내에 파일 전송 시스템을 구현할 수 있다는 것과 응용 프로그램의 확장 가능한 특성이다. In this paper, we propose a extensible file transfer system supporting FTP and data deduplication. The proposed system can be extensible by using various file transfer modules that provide traditional file transfer protocol and data deduplication such as fixed-length scheme and variable-length scheme. The key idea of this approach is to provide the rapid development of recent file transfer technology and extensible characteristics of the application.
