Book Announcement: Sound Visualization and Manipulation
The movie
Gravity
won seven Oscar awards this year, one of which was for its outstanding 3D sound mixing, immersing viewers in the full experience of the troubled space expedition.
3D audio effects are generated by manipulating the sound produced by speakers, speaker-arrays, or headphones to place a virtual sound source at a desired location in 3D space such as behind, above, or below the listener's head.
Two professors from the Department of Mechanical Engineering at KAIST have recently published a book that explains two important technologies related to 3D sound effects: sound visualization and manipulation.
Professor Yang-Hann Kim, an eminent scholar in sound engineering, and Professor Jung-Woo Choi collaborated to write Sound Visualization and Manipulation (Wily 2013), which uniquely addresses the two most important problems in the field in a unified way.
The book introduces general concepts and theories and describes a number of techniques in sound visualization and manipulation, offering an interrelated approach to two very different topics: sound field visualization techniques based on microphone arrays and controlled sound field generation techniques using loudspeaker arrays.
The authors also display a solid understanding of the associated physical and mathematical concepts applied to solve the visualization and manipulation problems and provide extensive examples demonstrating the benefits and drawbacks of various applications, including beamforming and acoustic holography technology.
The book will be an excellent reference for graduate students, researchers, and professionals in acoustic engineering, as well as in audio and noise control system development.

Welcoming the Class of 2014
“The four years from today will go quickly, and I urge you to make the most of your time in KAIST, a great educational and research institution where you will explore the frontiers of science and technology and take part in the creation of new knowledge,” President Kang told the freshmen at the convocation ceremony.
Freshmen Convocation for the Class of 2014 took place on March 3, 2014 at the auditorium on the main campus. Members of the KAIST community, along with hundreds of parents and guests, welcomed the incoming 800 freshmen, celebrating the beginning of their four-year college life.
Kwang-Joon Ahn, a graduate of the Korea Science Academy, and Ha-Rim Jin, a graduate of Daegu Il Science High School, were representatives of the incoming students, and they took the “Class of 2014 Pledge,” a commitment to uphold KAIST’s core values, which is "creativity and challenge (endeavoring spirit)," and to pursue intellectual passion and discovery.
President Steve Kang delivered congratulatory remarks, encouraging students to use their opportunities to the fullest while at KAIST to broaden their knowledge and experience. He also stressed the following four important principles they should cultivate to become the leaders of tomorrow: be grateful, excel in their field, keep open minds about what the globalized world would bring, and never give up on their dreams and belief.
President Kang said:
“Probably, many of you, the graduates of the best high schools in Korea, will find KAIST a tougher place to be in than you imagined. But challenges, particularly intellectual challenges, should be viewed as an opportunity to grow. It is ok to fail. In fact, without risking failures, there won’t be a meaningful growth because the real growth comes from overcoming challenges.”
“You can’t avoid failing in the course of your college life, but your perseverance to do it over will allow you to develop the skills and passion needed to become a leader who will contribute to the local community, as well as to the betterment of humanity.”
The KAIST Alumni Scholarship Foundation presented a scholarship of USD 3,700 to 24 freshmen.
The convocation ended with music performances by members of the student clubs at KAIST.

KAIST President Held One-year Anniversary Press Conference
President Steve Kang had a press conference
on February 25, 2014 at the Faculty Club on campus, commemorating the first
year of his presidency. About 30 different media representatives nationwide
attended the meeting.
At his first press conference on the anniversary of his tenure, President Kang
described what he has achieved in the past year, which were: 1) rebuilding the
campus culture to start a campaign for mutual respect, trust, and open
communication by holding meetings with the members of the KAIST community more
than 60 times, 2) establishing core values, creativity and challenge, to
enhance the fabric of the community, 3) restructuring of the university
administration, and 4) the announcement of the mid- and long-term development
plan.
He also mentioned that “2014 will be another exciting year for KAIST to make
more progress” and laid out a few major projects to be implemented this year:
launching of the “Committee for Engineering Education Innovation,” “Startup
KAIST” (an entrepreneurship program), “Greater Collaboration in Technology
Translation and Management with Seoul National University,” and “KAIST End Run”
(a global business incubation program).Explanation of 2014 Major Endeavors by President KangFor
the past decade, domestic engineering schools weighed SCI dissertation
publication more heavily in university evaluations, yielding a world-class
research level. However, such an approach resulted in placing less importance
on entrepreneurship, commercialization, or creating economic values.As a
result, engineering Professors have been evaluated as being too focused on theoretical
SCI dissertation research rather than practical research that could yield
economic benefits through commercialization of developed technology. In
addition, some have criticized that engineering universities have not educated
creative researchers demanded by the industry.KAIST
has begun responding to these criticisms and has made a few suggestions to strengthen
engineering education, promote entrepreneurship in engineers, and globalize Korean
venture companies.As
part of such efforts, KAIST established the KAIST Education and Research
Innovation Committee, composed of various individuals from the industry,
research institutes, alumni, faculty members, and others, to discuss ways to reinforce
engineering education.
A
course to encourage entrepreneurship will be implemented.Startup
KAIST will develop and commercialize innovative ideas from members of KAIST, and
the End Run project will enable students and faculty to establish a global,
venture company. KAIST hopes that a new entrepreneurial culture will be created
on campus, thereby the research success of KAIST members will lead to commercialization
and startups.KAIST
plans on releasing free internet lectures as part of its knowledge contribution
and sponsoring programs which will level the playing field in eduation.KAIST
will establish the KAIST Open Online Course (KOOC). An entrepreneurship
curriculum will be developed for KOOC. KAIST will start trials for KOOC from
2015, gradually expanding to include more courses.

Success in Measuring Protein Interaction at the Molecular Level
Professor Tae Young Yoon
- Live observation of two protein interaction in molecular level successful- The limit in measurement and time resolution of immunoprecipitation technique improved by a hundred thousand fold
KAIST Department of Physics Professor Tae Young Yoon’s research team has successfully observed the interaction of two proteins live on molecular level and the findings were published in the October edition of Nature Protocols.
Professor Yoon’s research team developed a fluorescent microscope that can observe a single molecule. The team grafted the immunoprecipitation technique, traditionally used in protein interaction analysis, to the microscope to develop a “live molecular level immunoprecipitation technique”. The team successfully and accurately measured the reaction between two proteins by repeated momentary interactions in the unit of tens of milliseconds.
The existing immunoprecipitation technique required at least one day to detect interaction between two proteins. There were limitations in detecting momentary or weak interactions. Also, quantitative analysis of the results was difficult since the image was measured by protein-band strength. The technique could not be used for live observation.
The team aimed to drastically improve the existing technique and to develop accurate method of measurement on molecular level. The newly developed technology can enable observation of protein interaction within one hour. Also, the interaction can be measured live, thus the protein interaction phenomenon can be measured in depth.
Moreover, every programme used in the experiment was developed and distributed by the research team so source energy is secured and created the foundation for global infra.
Professor Tae Young Yoon said, “The newly developed technology does not require additional protein expression or purification. Hence, a very small sample of protein is enough to accurately analyse protein interaction on a kinetic level.” He continued, “Even cancerous protein from the tissue of a cancer patient can be analysed. Thus a platform for customised anti-cancer medicine in the future has been prepared, as well.”

Venture Incubation Program: "Startup KAIST"
Making KAIST’s research accomplishments accessible outside the university to benefit Korea and beyond, as well as spurring the process of knowledge and technology transfer between academia and industry
KAIST launched a new business incubation program, called “Startup KAIST,” to support the growth of venture companies in late November 2013.
The program fosters a spirit of innovation and entrepreneurship on campus while advancing the development and commercialization of new discoveries and technologies made at the labs of the university.
Startup KAIST promotes entrepreneurship culture among faculty, students, researchers, and alumni; supports the full cycle of a startup ecosystem from the introduction, growth, maturity, and liquidation of new companies; encourages the development of globally sustainable startups; and collaborates with the Daedeok Innopolis, the largest science and technology research, development and business complex in Korea that is located adjacent to KAIST in Daejeon, to expand the startup program to the nation and the global community.
Under the program, the Startup KAIST Studio will be established. The entire third floor of the Education Support Building on campus is dedicated to startup activities where aspiring entrepreneurs come to network, develop new ideas and innovations, and share information and knowledge.
With a total of 24,000 square feet space, the Studio has neither partitions nor cubicles, thereby promoting open communication. It has seminar rooms, a high-tech-equipped conference room, an exhibition hall, offices, and cafés. The Startup Studio will be available for use from March 2014.
In addition to administrative services, Startup KAIST will offer a variety of courses, forums, and conferences on such subjects as entrepreneurship, technology management, intellectual property, and venture capital, along with training and mentoring programs on how to organize a company, secure funding, and pursue entrepreneurial visions.
Seeking active collaborations with alumni, industry, and other science and technology universities through Startup KAIST, the university will redouble its endeavor to form early-stage venture companies. Seasoned professional coordinators or volunteering entrepreneurs will stay at the Startup KAIST Studio to provide timely support for members of the KAIST community.
President Steve Kang said, “Startup KAIST is a one-stop service to create a new, strong company, small and medium size in particular, around innovations and disruptive technologies developed at KAIST and its adjacent research complex, Daedeok Innopolis.”“One of the important roles assigned to a research university today is to become a catalyst for knowledge and technology transfer among society, industry, and academia, upon which the advancement of humanity can build. KAIST will become a sounding board for engineers and scientists aspiring to launch a venture company to address their questions and concerns and to guide them through the startup process,” President Kang explained the need for implementing the Startup KAIST program.

President of WIPA Sang-Hui Lee and SK Hynix Awarded the 2013 Intellectual Property Award
The ceremony for the 3rd Intellectual Property Award was held at the KAIST campus in Seoul on November 2nd. The award is given annually to Korean practitioners in intellectual property.
This year’s recipients were Sang-Hui Lee, the president of the World Intellectual Property Association of Korean Practitioners (WIPA) and the SK Hynix Patent Group which successfully defended a long-lasting claim against a patent specialist corporation.
The Intellectual Property Award (IP Award) is presented in recognition to Korean individuals or groups that contributed to national competitiveness through creation, application, or proceedings of intellectual property, as well as to building the foundation for the protection of patents, intellectual properties, and trademarks.
President Lee successfully hosted the Global Intellectual Property Summit in Seoul, which was held in October 2012. He was a crucial force behind the foundation of WIPA in May of this year and was also elected as the first president for the organization. Recently, President Lee has been at the forefront of job creation through the efficient use of intellectual property and the creative discovery of venture endeavors.
President Lee said, “The unique characteristic of a knowledge-based society lies in the collaboration network of people and knowledge property, startups based on intellectual property, and decentralized development.”
He added, “Just as Finland adopted a policy to build venture companies in utilization of intellectual properties and encouraged the decentralized growth throughout the nation after the collapse of Nokia, Korea must adapt to meet the changing requirements of the knowledge-intensive era.”
The SK Hynix Patent Group, another recipient for the Intellectual Property Award, won the lawsuit, dragged on for 13 years, against the Rambus, an American patent specialized corporation. The group initially lost the first trial in the federal court of California, but through relentless research and efforts, they won the case in the appeals court. The IP Award was co-hosted by the Korea Patent Attorney Association, the Korea Intellectual Property and Service Association, and KAIST.

Short Wavelength, Ultra-High Speed Quantum Light Source based on Quantum Dot Developed
Professor Yong Hoon, Cho (Department of Physics) and his research team synthesized an obelisk nanostructure and successfully formed a single semiconductor quantum exhibiting high reliability to realize an ultra-high speed, highly efficient, release of quantum dots.
The result of the research effort was published in the July 5th online edition of Scientific Reports published by Nature.
Semiconductor Quantum Dots restrict electrons within a cubic boundary of few nanometers thereby exhibiting similar properties to an atom with discontinuous energy levels. Exploitation of this characteristic makes possible the development of quantum light source, critical for next generation quantum information communication and quantum encryption.
High operational temperatures, stability, rapid photon release, electric current capability, and other advantages are reasons why semiconductor quantum dots are regarded as next generation core technology.
However conventional, spontaneously formed quantum dots are densely packed in a planar structure rendering the analysis of a single quantum dot difficult and result in the poor efficiency of photon release. In addition, the internal electromagnetic effect which is caused by inter-planar stress results in low internal quantum efficiency due to the difficulty in electron-hole recombination.
Professor Cho’s research team synthesized an obelisk shaped nanostructure using nitrides that emit short wavelengths of light. The activation layer was grown on the tip of the nanostructure and the team succeeded in placing a single quantum dot on the nano-tip. The team was therefore able to confirm the ultra-high speed single photon characteristics which occur at low energy levels.
Use of unique nanostructures makes synthesis of single atomic structures without processes like patterning while enabling the release of light emitted by the quantum dot.
Using this unique method the team showed the increase in internal quantum efficiency. The electromagnetic forces apparent in thin films no longer affects the quantum dot greatly due to the obelisk structure’s reduced inter planar stress.
The newly developed quantum light source emits visible light (400nm range) and not the conventional infrared light. This characteristic makes possible it use in communication in free space and enables use of highly efficient, visible range photon detector.
Professor Cho commented that “the developed method makes quantum dot growth much easier making single photon synthesis much faster to contribute to the development of practical quantum light source.” And that “the characteristics of the obelisk nanostructure enable the easy detachment from and attachment to other substrates enabling its use in producing single chip quantum light source.”
The research was conducted under the supervision of Professor Cho. The researchers werey Jae Hyung, Kim (first author) and Yong Ho, Ko (second author), both Ph.D. candidates at KAIST. The Ministry of Science, ICT and Future Planning, the National Research Foundation, and WCU Program provided support to the research effort.
