KAIST Professor Whang Turns VLDB Journal Into One of the Best in Its Field
Kyu-Young Whang, a Distinguished Professor at KAIST’s Computer Science Department, has developed The VLDB Journal into one of the world’s best journals on database technology.
Professor Whang, Editor-in-Chief of The VLDB Journal, is credited for the journal’s remarkable success evidenced by the rise of the publication’s Science Citation Index (SCI) impact factor from 3.818 to 6.8 in the period of one year. This placed the VLDB in the first place amongst 99 information systems journals and 44 hardware and architecture-related journals registered with the SCI. With only the exception of the Survey Journal, this makes The VLDB Journal the best in computer science.
The VLDB Journal is a quarterly journal published on behalf of the VLDB Endowment. The journal, launched in 1992, is dedicated to the publication of scholarly contributions to the advancement of information system architectures, the impact of technological advancements on information systems, and the development of novel database applications.
The VLDB Journal’s closest competitors in database technology, IEEE Transactions on Knowledge and Data Engineering and ACM Transactions on Database Systems, received an impact factor of 2.236 and 1.613 respectively. Comparatively, Professor Whang’s journal retains an impact factor nearly 3 to 4 times greater.
During Professor Whang’s six-year term as Editor-in-Chief, he has actively pursued the use of innovative ideas, strengthened the board of editors, standardized the length of review time, and made the journal much more accessible through the Internet. Furthermore, he drastically reduced publication time and sought a policy that focused more on the journal’s readers, which led to The VLDB Journal’s SCI impact factor rising from 1.149 (2002) to 6.8 (2008).
As one of The VLDB Journal’s founding members, Professor Whang has worked for the advancement of his journal tirelessly for 19 years with many accomplishments in database technology, including physical database design, determining the quality of a database, and the creation of a database management system. As a result, Professor Whang became the first IEEE fellow concerning domestic computer science. He is also a trustee of The VLDB Endowment, a fellow of the Korean Academy of Science and Technology, and of course, a Distinguished Professor at KAIST.

Prof. Choi Unveils Method to Improve Emission Efficiency of OLED
A KAIST research team led by Prof. Kyung-Cheol Choi of the School of Electrical Engineering & Computer Science discovered the surface plasmon-enhanced spontaneous emission based on an organic light-emitting device (OLED), a finding expected to improve OLED"s emission efficiency, KAIST authorities said on Thursday (July 9).
For surface plasmon localization, silver nanoparticles were thermally deposited in a high vacuum on cathode. Since plasmons provide a strong oscillator decay channel, time-resolved photoluninescene (PL) results displayed a 1.75-fold increased emission rate, and continuous wave PL results showed a twofold enhanced intensity.
"The method using surface plasmon represents a new technology to enhance the emission efficiency of OLED. It is expected to greatly contribute to the development of new technologies in OLED and flexible display, as well as securing original technology," Prof. Choi said.
The finding was published in the April issue of Applied Physics Letters and the June 25 issue of Optics Express. It will be also featured as the research highlight of the August issue of Nature Photonics and Virtual Journal of Ultrafast Science.

U.S. and Korean Researchers Unveil Newest Research Team Member: Jaemi the Humanoid
- Project aims to enable humanoids to interact with people and their environment
June 1, 2009-- A Drexel University-led research team late last week unveiled the newest, most central member of its collaboration with a team of Korean researchers: Jaemi, a humanoid (HUBO). Jaemi HUBO embodies efforts to advance humanoid development and enhance the concept of human-robotic interaction. The project"s goal is to enable humanoids to interact with their environment, and enhancement plans include enabling the humanoid to move over rugged terrain, in unstructured environments and to interact socially with humans and handle objects.
The five-year project, funded through the National Science Foundation (NSF) Partnership for International Research and Education (PIRE) program, seeks transformative models to catalyze discovery through international research collaboration and train U.S. students and junior researchers to effectively think and work in global teams.
"The field of robotics is among the top 10 technology areas considered engines for economic growth. Korea understands this and is aggressively pursuing robotics. To stay competitive, the U.S. must do the same," said Mark Suskin, acting deputy director of NSF"s Office of International Science and Engineering. "NSF"s PIRE program and this robotics collaboration in particular, enable the U.S. to capitalize on research in other countries and remain competitive."
The PIRE research team is composed of researchers at The University of Pennsylvania, Colby College, Bryn Mawr College and Virginia Tech in the United States; and Korea Advanced Institute of Science and Technology (KAIST), Korea University and Seoul National University in Korea.
The team obtained a version of KAIST"s HUBO humanoid, which it named Jaemi HUBO and decided to house it at Drexel University. KAIST HUBO lab has become a model of cutting advance humanoid research by relatively small teams working on tight budgets.
KAIST excels in humanoid leg and body design, biped gait (walking, running, kicking), balance (modeling and control system design), and hardware integration. U.S. robotics researchers tend to enjoy an edge in locomotion over rugged, unstructured terrain; manipulation/grasping; cognition, perception and human-robot interaction; and vision (image, understanding, navigation).
This collaboration of American and Korean researchers will seek to draw on the expertise of each researcher and take Jaemi HUBO to the next level of development--that is, to improve Jaemi"s capabilities to navigate and manipulate objects and interact with people in unstructured environments. Such capabilities demand information technologies like cognition, perception and networking areas. Targeted enhancement features include a capability to move over rugged terrain and in unstructured environments and to handle objects and interact socially with humans.
Jaemi HUBO will also educate the American public, particularly young people, about the science of robotics. This education process began at the Please Touch Museum in Philadelphia on May 28, 2009, when Jaemi HUBO was unveiled and introduced to a crowded audience of children and a few adults. Neither male nor female,Jaemi connected with the children, boys and girls alike. Guided by a Drexel University graduate student, Jamei moved, spoke, danced, shook hands and lead the children in a game of Simon Says. Such access to Jaemi HUBO starkly contrasts with that afforded by other high-profile humanoids that are often protected trade secrets, largely inaccessible to the public.
Museum curators are pleased to have had Jaemi visit and entertain kids during the weekend. "At the Please Touch Museum, we promote learning through a variety of senses," said J. Willard Whitson,the museum"s vice president for exhibits and education. "A humanoid not only embodies our goal of building layers of knowledge in young people, but Jaemi helps all of us celebrate the playful side of technology."
Jaemi HUBO is now at its permanent home at Drexel University, from which travel and guest appearances may be arranged by appointment. Journalists interested in meeting and interviewing Jaemi HUBO and other research team members are encouraged to contact Lisa-Joy Zgorski at lisajoy@nsf.gov.

Prof. Cho Identifies Dynamics of Signal Transportation System in Control of Cell Proliferation
KAIST, Jan. 22, 2009 -- A research team led by Prof. Kwang-Hyun Cho of the Department of Bio and Brain Engineering, KAIST, has identified a hidden mechanism of the dynamic behavior of signal transportation system involved in the control of cell proliferation, university authorities said.
The finding is expected to provide a clue to appropriately controlling the pathway of ERK protein which is known to play a significant role in causing and spreading cancer. The research was featured as the cover paper of the latest online edition of the Journal of Cell Science.
The Ras-Raf-MEK-ERK pathway (or ERK pathway) is an important signal transduction system involved in the control of cell proliferation, survival and differentiation. However, the dynamic regulation of the pathway by positive- and negative-feedback mechanism, in particular the functional role of Raf kinase inhibitor protein (RKIP) are still incompletely understood. RKIP is a physiological endogenous inhibitor of MEK phosphorylation by Raf kinases, but also participates in a positive-feedback loop in which ERK can inactivate RKIP.
"We attempted to unearth the hidden dynamics of these feedback mechanisms and to identify the functional role of RKIP through combined efforts of biochemical experiments and computer simulations based on an experimentally validated mechanical model," Prof. Cho was quoted as saying.
