KAIST to build large-scale civil engineering experiment center
- Geo-Centrifuge experiment center of an area of about 1,712 square meters and an estimated construction cost of total 8.4 billion won
- Simulation laboratory in the field of geotechnical engineering with state-of-the-art experiment equipment- Ground-breaking ceremony held on April 3 at 4 pm
KAIST will construct ‘distributed shared-type Geo-Centrifuge experiment center’, a large-scale civil engineering laboratory that will study natural disasters such as earthquake, embankment collapse, etc. with ground structure miniatures.
A two-story building with a basement occupying an area of about 1,712 square meters will become a landmark laboratory in the field of geotechnical engineering that can be used for the education, research, and social infrastructure design by universities, institutes, and corporations via high-speed information and communication network. The estimated construction cost is 8.4 billion won.
The center will be composed of experiment building including geo-centrifuge laboratory, model-making room, workshop, geotechnical engineering laboratory, and specimen storehouse; and research building including control room, video conference room, electronic library, and research rooms. A variety of convenience facilities for researchers and video conference and remote monitoring system, with which researcher at remote distances can directly participate in experiments, will be provided in the research building, and world’s top-class experiment equipment such as geo-centrifuge with a turning radius of 5 meters, a maximum acceleration of 130 G (130 times faster than the acceleration of gravity), a preload of 2,400 kg and bidirectional shaking-table that can reproduce earthquakes-like wave during experiments, and robots that can reproduce construction procedures by a remote control will be installed.
Geo-Centrifuge experiment refers to an experiment that reproduces natural disaster-like motions by making miniatures of large-scale ground structures such as dams, slopes, etc. and using centrifugal forces generated from high-speed rotation. This experiment can easily and rapidly reproduce actual motions of ground structures at a low cost, thereby being widely used for various geotechnical engineering researches such as evaluation of seismic safety, movement of soft ground, slope stability analysis, etc. The causes of the embankment collapse in New Orleans by Hurricane Katrina in 2005 were also revealed by simulation tests by this experiment.
“The center will make possible a variety of experiments and researches that have never been available in Korea due to the lack of experiment infrastructure, therefore activate researches over the design and construction of large-scale social infrastructures. Making possible civil engineering researches demanding the use of large-scale equipment like Centrifuge, severely dependent on overseas technologies so far, will enhance the global competitiveness of Korean construction industry,” said Dong-soo Kim, President of the center.
The center will be constructed as part of the Ministry of Construction & Transportation (MOCT)’s project for the establishment of distributed shared-style construction research infrastructure, which is designed to establish construction research infrastructures in a national level. The ground breaking ceremony was held at KAIST on April 3 at 4 pm.

Youngseok Son and Yongjoon Chun won a prize of Commerce, Industry and Energy Minister
Youngseok Son and Yongjoon Chun won a prize of Commerce, Industry and Energy Minister
Youngseok Son and Yongjoon Chun, doctorate students at circuit design and system application lab of Electrical Engineering Division, won a prize of Commerce, Industry and Energy Minister (Silver prize) at the 7th Semiconductor Design Contest hosted by the Korean Intellectual Property Office.
Their work exhibited at the contest is ‘a driving circuit for the improvement of image quality of AMOLED display’.
AMOLED display is gaining attention as a next-generation display for its numberless advantages compared to AMLCD and PDP, however, problems over the image quality and lifespan of the display have disturbed the substantial development. Their work verified its electrical features by proposing and designing the driving method and circuit for the improvement of the image quality and lifespan of AMOLED display. The announced driving method was named ‘Transient Cancellation Feedback (FCF)’ and its concept was published in SID 2006. Their work was evaluated to overcome the limitation of the existing driving methods by providing an intrinsic Active Matrix structure, different from the existing driving methods.
It is also evaluated to strikingly enhance the speed and accuracy of data current driving through TCF driving. It is expected to significantly enhance the image quality and lifespan of AMOLED displays by applying TCF driving.
