Nowadays, High-rise building becomes higher and bigger than ever. As a result, lots of construction materials are needed at the same times. Because of divided diverse process of construction, several different Processes concur simultaneously with complexity of procurement. So, effective construction material supply and lift-up are essential part of the spot. Especially, when ending part of construction, there are much conflict between finishing and equipment materials also problems of folding lift-up. The Purpose of this paper is suggesting better effective lift-up system through analysis of loading factors.

The purpose of this study is to describe the current practises and procedure of building the authority file for corporate names and conference names for Korea Institute of Science and Technology Information Authority Database, and the characteristics of OCLC WorldCat and Library of Congress Authorities Database as the sources for importing authority records. Workflow of creating authorities records is explained and the structures and search strategies for OCLC and LC databases are compared and analyzed. The actual procedures of importing records from outside sources and revising their contents to represent KISTI's needs are described step by step, and records are illustrated.

The Korea Atomic Energy Research Institute (KAERI) constructed the PyRoprocessing Integrated inactive Demonstration facility (PRIDE) to carry out experiments on engineering scale pyroprocessing. PRIDE has a large processing cell that human workers are not allowed to access, and thus the equipment inside is operated from outside using remote handling systems. It is therefore essential to examine the operability and maintainability of the equipment in view of remote handling systems, and the equipment is thoroughly examined in a mockup cell before it is installed in the processing cell. If the equipment is tested in a virtual mockup rather than in a mockup cell, the development cost can be significantly reduced. The PRIDE 3D simulator was integrated for virtual verification of equipment that will be installed in the processing cell. All remote handling devices in the actual PRIDE were also virtually installed in the PRIDE 3D simulator. The 3D model of the equipment was loaded and located in the exact position in the virtual processing cell. A scenario to replace an actual electrode was implemented in the PRIDE 3D simulator. The design of the equipment and the working procedures in the scenario were successfully evaluated. The results demonstrated that the PRIDE 3D simulator can be used successfully as an alternative to actual mockup testing.

Export containers in a container terminal are usually classified into a few weight groups and those belonging to the same group are placed together on a same stack. The reason for this stacking by weight groups is that it becomes easy to have the heavier containers be loaded onto a ship before the lighter ones, which is important for the balancing of the ship. However, since the weight information available at the time of container arrival is only an estimate, those belonging to different weight groups are often stored together on a same stack. This becomes the cause of extra moves, or rehandlings, of containers at the time of loading to fetch out the heavier containers placed under the lighter ones. In this paper, we use machine learning techniques to derive a classifier that can classify the containers into the weight groups with improved accuracy. We also show that a more useful classifier can be derived by applying a cost-sensitive learning technique, for which we introduce a scheme of searching for a good cost matrix. Simulation experiments have shown that our proposed method can reduce about 5$\sim$7% of rehandlings when compared to the traditional weight grouping method.

차세대관리 종합공정 실증시설의 핫셀 차폐벽은 중량콘크리트 재질로서 외벽의 두께는 90cm 이상으로 설계되었으며, 차폐벽의 모든 부위는 이와 동일한 차폐능을 확보하도록 하여야 한다. 그러나 핫셀 운영을 위하여 불가피하게 설치되는 여러 가지 부속 시설물들에 의하여 원래 계획한 핫셀 차폐벽의 차폐능 저하를 가져오게 되며, 이런 부속 시설물로는 차폐 출입문, 방사성 물질을 핫셀 내부로 반입하거나 반출하기 위한 수송용기 접합부, 소형물 투입구, 슬리브 및 매설관등이 있다.(중략)

유기성 폐기물은 음식물쓰레기, 농ㆍ수ㆍ축산폐기물, 식품가공산업 폐기물 등에서 주로 발생되고 있다. 이러한 유기성 폐기물은 함수율이 70∼85% W.B.정도로 높고 부패성이 크기 때문에 악취 및 침출수 등의 여러 가지 환경유발 가능성이 높은 것으로 평가되고 있다. 최근에는 이러한 젖은 폐기물의 매립장 반입이 규제되고 있으며, 함수율이 높아 직접 소각도 어려운 실정이므로 유기성 폐기물의 안정화, 감량화 및 재자원화를 위한 처리기술개발이 시급한 실정이다.(중략)

외국에서 수입하거나 반입하는 물품에 대해 세관에서 징수하는 관세는 기업의 원가절감과 직결되고, 그만큼 정부의 지원이 필요하다. 그러나 현재 복사기, 카메라 생산 업체들은 산업현실과 맞지 않는 불합리한 관세제도로 국제시장에 경쟁력을 확보하는 데 많은 어려움을 겪고 있다. 복사기업체는 '부분품과 부속품'(HS/9009.90.0000)에 속하지 않더라도 모두 복사기 부품으로 인정해 동일한 관세율을 적용해 줄 것을 요구한다. 카메라 생산 업체는 각기 입장이 다

In this study, the influence of workability and strength of the concrete according to change temperature of portland cement were investigated by measurements of slump, air content and compressive strength.. As a result, ready mixed concrete using 5-20% mineral admixtures such as fly ash, blast furnace slag were desirable to prevent the increase in workability and strength of concrete in summer season
