Attachable Skin Monitors that Wick the Sweat Away
- A silicone membrane for wearable devices is more comfortable and breathable thanks to better-sized pores made with the help of citric acid crystals. -
A new preparation technique fabricates thin, silicone-based patches that rapidly wick water away from the skin. The technique could reduce the redness and itching caused by wearable biosensors that trap sweat beneath them. The technique was developed by bioengineer and professor Young-Ho Cho and his colleagues at KAIST and reported in the journal Scientific Reports last month.
“Wearable bioelectronics are becoming more attractive for the day-to-day monitoring of biological compounds found in sweat, like hormones or glucose, as well as body temperature, heart rate, and energy expenditure,” Professor Cho explained. “But currently available materials can cause skin irritation, so scientists are looking for ways to improve them,” he added.
Attachable biosensors often use a silicone-based compound called polydimethylsiloxane (PDMS), as it has a relatively high water vapour transmission rate compared to other materials. Still, this rate is only two-thirds that of skin’s water evaporation rate, meaning sweat still gets trapped underneath it.
Current fabrication approaches mix PDMS with beads or solutes, such as sugars or salts, and then remove them to leave pores in their place. Another technique uses gas to form pores in the material. Each technique has its disadvantages, from being expensive and complex to leaving pores of different sizes.
A team of researchers led by Professor Cho from the KAIST Department of Bio and Brain Engineering was able to form small, uniform pores by crystallizing citric acid in PDMS and then removing the crystals using ethanol. The approach is significantly cheaper than using beads, and leads to 93.2% smaller and 425% more uniformly-sized pores compared to using sugar. Importantly, the membrane transmits water vapour 2.2 times faster than human skin.
The team tested their membrane on human skin for seven days and found that it caused only minor redness and no itching, whereas a non-porous PDMS membrane did.
Professor Cho said, “Our method could be used to fabricate porous PDMS membranes for skin-attachable devices used for daily monitoring of physiological signals.”
“We next plan to modify our membrane so it can be more readily attached to and removed from skin,” he added.
This work was supported by the Ministry of Trade, Industry and Energy (MOTIE) of Korea under the Alchemist Project.
Image description:
Smaller, more uniformly-sized pores are made in the PDMS membrane by mixing PDMS, toluene, citric acid, and ethanol. Toluene dilutes PDMS so it can easily mix with the other two constituents. Toluene and ethanol are then evaporated, which causes the citric acid to crystallize within the PDMS material. The mixture is placed in a mould where it solidifies into a thin film. The crystals are then removed using ethanol, leaving pores in their place.

Skin Hardness to Estimate Better Human Thermal Status
(Professor Young-Ho Cho and Researcher Sunghyun Yoon)
Under the same temperature and humidity, human thermal status may vary due to individual body constitution and climatic environment. A KAIST research team previously developed a wearable sweat rate sensor for human thermal comfort monitoring. Furthering the development, this time they proposed skin hardness as an additional, independent physiological sign to estimate human thermal status more accurately. This novel approach can be applied to developing systems incorporating human-machine interaction, which requires accurate information about human thermal status.
Professor Young-Ho Cho and his team from the Department of Bio and Brain Engineering had previously studied skin temperature and sweat rate to determine human thermal comfort, and developed a watch-type sweat rate sensor that accurately and steadily detects thermal comfort last February (title: Wearable Sweat Rate Sensors for Human Thermal Comfort Monitoring ).
However, skin temperature and sweat rate are still not enough to estimate exact human thermal comfort. Hence, an additional indicator is required for enhancing the accuracy and reliability of the estimation and the team selected skin hardness. When people feel hot or cold, arrector pili muscles connected to hair follicles contract and expand, and skin hardness comes from this contraction and relaxation of the muscles. Based on the phenomenon of changing skin hardness, the team proposed skin hardness as a new indicator for measuring human thermal sensation.
With this new estimation model using three physiological signs for estimating human thermal status, the team conducted human experiments and verified that skin hardness is effective and independent from the two conventional physiological signs. Adding skin hardness to the conventional model can reduce errors by 23.5%, which makes its estimation more reliable.
The team will develop a sensor that detects skin hardness and applies it to cognitive air-conditioning and heating systems that better interact with humans than existing systems.
Professor Cho said, “Introducing this new indicator, skin hardness, elevates the reliability of measuring human thermal comfort regardless of individual body constitution and climatic environment. Based on this method, we can develop a personalized air conditioning and heating system that will allow affective interaction between humans and machines by sharing both physical and mental health conditions and emotions.”
This research, led by researchers Sunghyun Yoon and Jai Kyoung Sim, was published in Scientific Reports, Vol.8, Article No.12027 on August 13, 2018. (pp.1-6)

Finding Human Thermal Comfort with a Watch-type Sweat Rate Sensor
(from left: Professor Young-Ho Cho and Researcher SungHyun Yoon)
KAIST developed a watch-type sweat rate sensor. This subminiature device can detect human thermal comfort accurately and steadily by measuring an individual’s sweat rate.
It is natural to sweat more in the summer and less in the winter; however, an individual’s sweat rate may vary in a given environment. Therefore, sweat can be an excellent proxy for sensing core body temperature.
Conventional sweat rate sensors using natural ventilation require bulky external devices, such as pumps and ice condensers. They are usually for physiological experiments, hence they need a manual ventilation process or high power, bulky thermos-pneumatic actuators to lift sweat rate detection chambers above skin for continuous measurement. There is also a small sweat rate sensor, but it needs a long recovery period.
To overcome these problems, Professor Young-Ho Cho and his team from the Department of Bio and Brain Engineering developed a lightweight, watch-type sweat sensor. The team integrated miniaturized thermos-pneumatic actuators for automatic natural ventilation, which allows sweat to be measured continuously.
This watch-type sensor measures sweat rate with the humidity rising rate when the chamber is closed during skin contact. Since the team integrated thermos-pneumatic actuators, the chamber no longer needs to be separated manually from skin after each measurement in order for the chamber to ventilate the collected humidity.
Moreover, this sensor is wind-resistant enough to be used for portable and wearable devices. The team identified that the sensor operates steadily with air velocity ranging up to 1.5m/s, equivalent to the average human walking speed.
Although this subminiature sensor (35mm x 25mm) only weighs 30 grams, it operates continuously for more than four hours using the conventional wrist watch batteries.
The team plans to utilize this technology for developing a new concept of cognitive air-conditioning systems recognizing Human thermal status directly; while the conventional air-conditioning systems measuring air temperature and humidity.
Professor Cho said, “Our sensor for human thermal comfort monitoring can be applied to customized or smart air conditioners. Furthermore, there will be more demands for both physical and mental healthcare, hence this technology will serve as a new platform for personalized emotional communion between humans and devices.”
This research, led by researchers Jai Kyoung Sim and SungHyun Yoon, was published in Scientific Reports on January 19, 2018.

2010 New Year Message
The State of KAIST in 2009 & 2010:
Assessing the Past Year’s Accomplishments and
Next Year’s Challenges and Opportunities
Nam Pyo Suh
President, KAIST
January 4, 2010
Summary
2009 was a great year for KAIST, with every member of the KAIST family working to cement KAIST’s position among the world’s leading universities. Faculty, staff and students alike have made unique and important contributions to toward this goal through major advances in research, education, and service. Our work in science, technology, and education will profoundly impact industry and society, in Korea and throughout the world. In addition to achieving major scientific discoveries and developing technologies and processes, our faculty has greatly improved KAIST’s curriculum and pedagogical practices. Many professors have been recognized by many organizations in and outside of Korea in 2009. Our students have contributed to KAIST through their involvement in research and a wide array of extracurricular activities. Our staff has accomplished a seamless merger of ICU and KAIST, in addition to managing a variety of other demanding projects. As a result of all of these contributions, KAIST is a stronger, more dynamic institution today than it was a year ago.
In the coming year, KAIST must continue its efforts to become one of the best universities in the world. While building on our previous accomplishments, we will face new challenges. We will have to identify and commence challenging research projects, while continuing to evolve our educational programs. We have several construction projects to complete. And we must continue to expand KAIST’s sphere of influence, collaborating with colleagues around the world. With our dedication to excellence, 2010 will be a productive and intellectually rewarding year.
Our past efforts have attracted attention both internationally and domestically. Our progress in education and research has been recognized by international ranking agencies (QS/The London Times) and domestic newspapers. For example, international ranking agency QS listed KAIST 21st in engineering and IT, 39th in sciences, and 69th overall -- from 243th in 2005 and 198th in 2006 – making KAIST the fastest rising university. And domestic newspapers, JoongAng Ilbo and Chosun Ilbo, rated KAIST the top university in Korea.
I am personally most grateful to thousands of financial contributors to KAIST, who have enabled us to undertake critical projects, both physical and academic. Thanks to their contributions, KAIST will continue to renovate and innovate in the years to come. Chairman Byung-Ho Kim made the largest gift in 2009, following the important tradition established by Chairman Moon-Sool Chung, Chairman Chong-Moon Lee, Dr. Byiung-Joon Park, Chairman Neil Pappalardo, Professor Geun-Chul Lyu, Chairman Donald C. W. Kim, Dr. Hyung-Kyu Lim, and many others. Their contributions will be remembered for establishing the tradition of philanthropic giving in Korea.
KAIST has also been fortunate to receive tremendous support from the Korean government. The government and the National Assembly have enabled KAIST to undertake two ambitious and bold projects: the On-Line Electric Vehicle (OLEV) project and the Mobile Harbor (MH) project. By demonstrating these projects’ success, we hope the government will continue to provide strong support in 2010, as we believe they will yield rich educational, scientific, technological, and economic returns to taxpayers.
CY 2009 – A Retrospective Assessment
CY 2009 has been a remarkable year for KAIST. We have made great strides in making KAIST into one of the best universities in the world, with a strategy that addresses the most important challenges of the 21st century – in the spheres of energy, environment, water and sustainability (EEWS) – through multi-disciplinary education, research, and technological innovation.
The following are the major highlights of the past year (listed in no particular order):
Education in 2009
1. Three years ago, KAIST developed educational and research strategies that have continued to evolve and improve. In education, our goals have been to admit the most capable students, to teach synthesis as well as analysis, and to produce graduates who can compete both globally and locally. To achieve the first goal, we have adopted new admissions policies, which have proved effective at bringing some of the best and the brightest minds to KAIST (see 6). Regarding the 2nd goal, freshman students are now required to take the freshman design subject to make them “bi-functional” in both synthesis and analysis. As for the 3rd goal, The Mileage Program continues to broaden the outlook of our undergraduate students. To make our students competitive globally, we have actively recruited international students and faculty and adopted English as the official language of instruction.
2. KAIST has tried to instill a sense of responsibility in our students. To this end, we have asked them to complete their prescribed degree programs within the allotted time. While we emphasize academic achievements, we also believe that health and physical exercise are also important. Therefore, we are constructing a new athletics facility to strengthen our students’ mental fortitude by augmenting it with active participation in sports and through physical exercise.
3. To re-focus our educational and research programs, we have re-organized KAIST into six Colleges and created three new academic departments. The six colleges are: College of Natural Science, College of Engineering, College of Information Science and Technology, College of Life Science and Bioengineering, College of Business, and College of Cultural Science. Four new academic units created in 2009 are the Department of Knowledge and Service Engineering in the College of Information Science and Technology, the Department of Ocean Systems and Graduate School of EEWS in the College of Engineering, and the Graduate School of Nano-Science and Technology in the College of Natural Science.
4. KAIST has also initiated new graduate-level educational programs in a number of fields -- ocean systems, nano-science and technology, EEWS, knowledge and service engineering, intellectual property, science and technology journalism, and Ph.D. education for medical doctors (MDs). We also have received strong support for the WCU programs in a number of fields from the Ministry of Education, Science and Technology (MEST).
5. In addition, we have strengthened our programs in systems and design in order to change the nature of engineering education and the intellectual perspective of the freshman at KAIST. Colleagues who have taught the freshman design course attest that it has achieved its educational goal -- Professors Kate Thompson and Taesik Lee have done a great job making it successful. We have also launched many new programs, including the Renaissance Ph.D. Program under the direction of Professor Dong-Yul Yang. Also, KAIST has two new masters of science (MS) programs – MS in Intellectual Property and MS in Science Journalism – under the leadership of Dean Kwang Hyung Lee. Professor Chul-Ho Kim will direct the MS in IP Program and Dean Kwang Hyung Lee will direct the MS in Science Journalism.
6. KAIST is committed to seeking and admitting talented students. In 2009, we initiated a new process for selecting and admitting the most qualified undergraduate students from normal high schools, in addition to continuing the interview-based admissions process introduced two years ago. Under the new process, the principal of each normal high school (there are roughly 1,300 in Korea) was asked to recommend one student for KAIST. After a preliminary screening by the Admissions Office, followed by an interview at the KAIST campus, 150 students were admitted from this group.
(These newly admitted students have been given the opportunity to make up for any deficiencies in mathematics, physics and chemistry by taking on-line KAIST courses. Dean Kwang Hyung Lee created the experimental Bridge Program this year, with over 130 high school students subscribing to complete the final semester of high school education. Mid-term examination results indicated that these students are thriving at KAIST.)
This new admissions process supplements the process successfully introduced two years ago, in which students are admitted based on interviews and high school grades only – a change that has proved of great interest to other universities in Korea. Using this process, KAIST will admit an additional 850 students from the Science High Schools, the Korea Science Academy, and normal high schools. The composition of the incoming 1,000-student freshman class is consistent with the goals established in the Five Year Plan.
7. KAIST has signed several agreements with universities and research institutes abroad for student exchanges, dual degree programs, and post-doctoral studies. In 2009, international students from 72 countries studied at KAIST. KAIST has also sponsored two recent Ph.D.s as post-doctoral fellows at the NASA Ames Research Center, California, United States.
8. In December 2009, as a part of the UAE-Korea agreement, KAIST agreed to collaborate with the Khalifa University of Science, Technology and Research (KUSTAR), the leading scientific and technological university in Abu Dhabi. Under this program, KAIST will aid KUSTAR with its educational and research programs in a number of fields. There will be an exchange of personnel and research collaboration, in addition to curricula development, establishment of laboratories, and infrastructure strengthening. This program is expected to last about ten years with a major review in five years.
Research in 2009
1. KAIST has developed a research strategy that will help it become a leader in the fields of science and technology. This strategy consists of a two-pronged approach: (a) encourage and support Faculty-Initiated Individual Research (FIIR) and (b) undertake concentrated, multidisciplinary, system-scale projects in a few select areas. The most important means of supporting FIIR has been KAIST’s Fellowship, HRHR , and EEWS Programs. To balance FIIR projects, KAIST has supported multi-disciplinary group research through the KAIST Institutes (KI) and also the EEWS Program.
2. KAIST has also provided start-up funds to new faculty members for equipment and other scholarly activities (rather than using the funds to support graduate students, since many of our incoming students are provided with fellowships).
3. In basic research, our professors and students have made important advances in sciences (e.g., mathematics, biology, chemistry, and physics). In technological innovation, KAIST has developed many new processes and technologies (e.g., applied biochemistry, biochemical processing, robotics, On-Line Electric Vehicle (OLEV), Mobile Harbor (MH), semiconductor processing, IC design, electronic packaging, fuel cells, optics, propulsion, complex systems, ship insulation, nanotechnology, and many others). These research contributions will gain international recognition as their results become better known and widely used.
4. To promote research collaboration between KAIST and leading European universities, the Office of External Affairs organized a trip to Europe. Five professors, Dean Yong-Taek Im, two students, and I visited four leading European universities – Technical University of Denmark, Delft University of Science and Technology, RWTH Aachen University, and Ecole Polytechnic/
ParisTech. On this trip, Professors Jie-Oh Lee and Yong-Mahn Han presented their work in biological chemistry and stem-cell research, respectively, and Professors Joong-Myeon Bae, Kyung-Cheol Choi, and Otfried Cheong presented their work on fuel cells, displays, and combinatorial geometry, respectively. These visits clearly indicated that KAIST is at the forefront of science and technology.
5. The OLEV and MH Projects are large, multi-disciplinary R&D projects specially funded through the 2009 Supplementary Budget. The goal of the OLEV Project, headed by Professor Dong-Ho Cho, is to eliminate internal combustion engines in order to lower CO2 levels in the earth’s atmosphere and to also help Korea reduce its imports of fossil fuels. Many professors and research staff members (Professors Chun-Taek Rim, Joung-Ho Kim, In-Soo Suh, Yong-Hoon Jeong, Hang-Ki Lee, and others) have worked on this project. A company named OLEV&E Company was established by the KAIST Development Foundation to attract industry involvement and accelerate the commercialization process as stipulated by the government as part of the 2009 Supplementary Budget. CEO Chung-Goo Lee, the former CEO of Hyundai Motors, is heading this commercialization effort. KAIST has developed OLEV buses and cars that draw electric power and recharge a small battery system from underground cables without any mechanical contact to power electric motors. The efficiency of power transmission is over 72% and the electromagnetic force (EMF) is well below specifications. This system is being installed in Seoul Grand Park. We have filed for many patents.
6. The goal of the Mobile Harbor project is to create “moving harbors” that can load and unload containers to and from large container ships and deliver them to small as well as large harbors -- the central goal being to eliminate the need for large, deep-water harbors by making “mobile harbors” that can go out to ships moored in deep waters. The team headed by Professor Byung-Man Kwak has demonstrated the viability of the original technology. Many professors – Professors Yun-Sik Park, Jun-Ho Oh, Gyung-Jin Park, Taesik Lee, Soon-Heung Han, Soo-Hyun Kim, and others -- have contributed to this project. The CEO of the Mobile Harbor Corporation, Daniel C. S. Ahn, and his team directed the design of two large mobile harbors, which will be submitted for certification for commercial use. We have many patents filed.
(It should be noted that initially, the OLEV and MH projects were supported by the EEWS project, the HRHR Initiatives, and KI.)
7. The EEWS has funded 24 projects related to 10 critical topics in EEWS: Solar Energy, Photosynthesis and Carbon Capture & Storage, Fuel Cell, Bio Fuel, Battery and Green Car, Safe Nuclear Energy, Enhancing Energy Efficiency, Environment Monitoring and Recovery, Sustainable Manufacturing and Building, and EEWS Strategies.
8. A number of the KAIST Institutes (KI) have been gaining momentum. The KI for IT Convergence, which has a great number of faculty members from many disciplines, is conducting joint research projects. The KI for Design of Complex Systems has developed complex insulations systems for special-purpose large vessels. There are many other achievements that will be noted in a more expanded report.
Merger
We have successfully merged ICU and KAIST to forge stronger programs in IT. This strengthened group at KAIST has initiated new research and education in IT. We also accepted the operational responsibility for the Korea Science Academy to foster creative and intelligent high school graduates, especially those interested in science and engineering.
Construction of New Buildings and Facilities
We are constructing several new buildings: the Chunghi and BJ Park KI Building for multidisciplinary research; the Pappalardo Medical Center; the Sports Complex; the International Center; an apartment complex for international faculty; and dormitories for students. We have also renovated many buildings (e.g., the student dining facilities). In addition to the seven new buildings under construction now, we will be building several new buildings: the Kim Byung-Ho IT building, the Second Chung Moon-Soul Building for Brain science and Engineering, and an Animal Facility. Construction will begin soon.
Faculty
1. As of December 2009, KAIST has 548 tenure-track professors and 322 non-tenure track professors. Of these, 39 are international faculty (including 20 Korean-Americans) and 34 are female. Our goal is to increase our international and female faculty to 20% each.
2. KAIST has appointed 56 outstanding new faculty members, including 15 international and 8 female members. The quality of these faculty members is exceptionally high. The search committees and department heads should be commended for an excellent recruiting job.
3. We have a truly outstanding faculty. Many members are known nationally and internationally for their contributions, and continue to receive awards for their work. Many of the young professors who recently joined KAIST are among the most outstanding scholars in their respective fields, showing much promise for KAIST’s future.
Students
1. In 2009, KAIST had 3,766 undergraduate students and 5,029 graduate students (2,456 MS candidates and 2,573 Ph.D. candidates). We have 289 more undergraduate students than we should have had, as these students have not completed all the requirements for their undergraduate degrees within the standard time frame. It is important that our students learn to complete their studies within the time allocated for their degrees, and for that matter, for any task. In order to encourage our graduate students to complete their formal academic training as soon as possible and assume long-term career paths, we have imposed a time limit for their tenure as graduate students.
2. To encourage students to finish their undergraduate studies in four years, we have instituted a tuition system that requires all students, regardless of GPA, to pay full tuition if they do not finish their undergraduate degrees within that time frame. MS students and Ph.D. students who do not finish their degree in two and five years, respectively, are also required to pay partial or full tuition.
The Pappalardo Medical Center
With the financial support of Chairman and Mrs. Neil Pappalardo, we are constructing the Pappalardo Medical Center. The purpose of the Pappalardo Medical Center is to provide primary care to KAIST family members -- students, staff, professors and their families. The Pappalardo Medical Center will be increasingly important as we have more members of the KAIST family who do not speak Korean. Thanks to the efforts of Professor Ook-Joon Yoo, Dean for the Graduate School for MD/PhD Program and the Director of the Center for Bio-Medical Research, the Pappalardo Medical Center will be dedicated in May 2010. Professor Yoo will soon be hiring medical and support staff for the medical center.
Meetings, Conferences, and Workshops
KAIST hosted many conferences and workshops in 2009, including the Second International Presidents Forum (IPF) and the International Workshop on EEWS. Hosting such events has served many important functions – increasing global visibility, teaching best practices, creating inter-personal connections, fostering financial support, and building good will throughout the world.
In Recognition of the Special Support of Government
Most of the new programs in education, research, and infrastructure construction described above have received strong budgetary support from the government. The top leaders of the Korean government have given us opportunities to explore bold new concepts in science and technology through the General Appropriation of the Budget and the special Supplementary Funding of 2009. We are grateful for their support. I am personally grateful to President M.B. Lee for his support of the OLEV and the Mobile Harbor Projects.

Gifts and Donations from Generous KAIST Supporters
KAIST has been extremely fortunate to receive generous financial support from many leaders, alumni, friends, and supporters. In just a few years, the number of donors has increased from a few hundred to over 3,000. In 2009, KAIST received major gifts from supporters: Chairman and Mrs. Byung-Ho Kim donated 30 billion won, Chairman and Mrs. Donald C.W. Kim of Hawaii donated US$1 million, Chairman Hui-Yul Bae of Japan provided a 1 billion won gift, alumnus Dr. Hyung-Kyu Im, President of Samsung, gave a second gift of 200 million won, and the family of Seung-Yul Chung donated 100 million won. There have also been many generous donors too numerous to list.
As we look ahead at fundraising goals, KAIST is still in need of 20 billion won to support its Sports Complex, after a generous donation of 5.6 billion won from Woori Bank and POSCO.
Board of Directors
The Board of Directors (BoD) is the governing body of KAIST. It sets the policies, approves appointments and the budget, and selects and appoints the President of KAIST. The support of the Board is essential in planning and executing KAIST programs.
The new chairman of the BoD is Dr. Moon-Soul Chung, the Board’s longest serving member. In 2009, joining the esteemed group, many outstanding leaders joined as new board members. New members include Mr. Donald C.W. Kim, the former Chairman of the Board of Trustees of the University of Hawaii and CEO of AMKOR A&E; Dr. Chong-Moon Lee, the Chairman of Ambex; Dr Byiung-Jun Park, the Founder and former CEO of MTL, Inc.; Dr. Geun-Chul Lyu, Professor Emeritus at Moscow Technological University; Attorney Joo-Myung Whang, the former Chairman of the Board of Trustees of ICU.

CY 2010 – Challenges and Opportunities
In 2010, we must continue to pursue the ultimate goal of making KAIST one of the best S&T universities in the world. This goal can be achieved through effective education and research. KAIST must offer educational programs that produce future leaders. The basic research done at KAIST should shape the future development of human knowledge and society, and the technologies developed at KAIST should be innovative enough to solve important problems in the 21st century. The plans of our colleges, departments, and KIs are attached in the Appendix. We should refine and modify them in 2010 with the ultimate goals of KAIST in mind.
Education in 2010 and beyond
In 2010, we should continue to improve our educational programs. We should further strengthen the Renaissance Ph.D. Program to be sure that KAIST produces engineers and scholars with advanced degrees, who can deal with both the design and analysis of complex systems. At the same time, we should strengthen undergraduate subjects that deal with design, following the successful development of the freshman design subject.
We should review our curricula to be sure that it is more codified, streamlined and simplified to make learning more effective and productive. It might benefit some students if we can teach them the essences of their chosen fields while providing enough flexibility for broad educational experiences and independent learning. Developing new subjects (or courses) is intellectually and physically demanding. Yet it is a necessary function of leading universities. We should recognize our major innovative contributions to education just as we do our innovative research.
Our students should finish their degrees within a reasonable period of time. Staying in school longer than necessary is a waste of both human talent and financial resources. Our students will find their true innate capabilities when they leave KAIST and pursue their careers. No one benefits by unnecessarily prolonging formal education. Certainly, the taxpayers should not be asked to bear the financial burden when a student is lax in fulfilling his or her share in the educational process.
KAIST should develop new educational materials, methods, aids and tools. The distance learning/teaching program – the Bridge Program initiated by Dean Kwang Hyung Lee to teach the high school students admitted to KAIST before they actually enroll at KAIST – is a good example of how modern IT can be used to increase the effectiveness and productivity of education.
Research – Basic Research
Basic research in science and engineering is the intellectual sustenance of research universities. Most basic research is often initiated and executed by individual professors, researchers, and students. They come up with ideas and seek answers to the problems posed. In addition to pursuing independent individual research, we must foster multi-disciplinary research at the interface between disciplines where rich intellectual issues and questions lie. KAIST as a leading research university must support the multi-disciplinary research conducted by a group of researchers from many disciplines. To achieve this goal, the KAIST Institutes (KIs) are providing both intellectual leadership and major new facilities. At this time, there are eight (8) KIs. They are concerned with energy, IT, nano-science, bio-science, environment, water, materials, and design. A new building is being constructed to better accommodate these activities.
We must constantly seek new ideas and problems that can yield rich intellectual dividends. Among the new multi-disciplinary subjects are brain research and high resolution MRIs.
Research -- Technology Innovation
At the opposite end of the research spectrum from basic research is technology innovation. A couple of major examples of technology innovation we have undertaken recently are the “on-line electric vehicle” and the “mobile harbor” projects. Another example is the new process of converting natural bio-products into polymers, which was the invention of Dean Sang-Yup Lee. We need to constantly probe new areas and problems that are ready for major technological innovations.
We have been asking how we can reduce the CO2 generation by jet engines and save 20% of the fuel consumed by current commercial airliners. While we have come up with a couple of ideas, nothing concrete had been developed. (Recently, other research has disclosed that a way of improving fuel efficiency of jet engines is to uncouple the speed of the fan from the compressor in turbojets. This shows that we have been probing the right questions.)
There are many other topics we could consider. We need major innovations in generating, handling, and using hydrogen. We also need new innovations in energy storage such as more efficient, lightweight batteries that can store and discharge electric energy at a much faster rate. We also need to develop medical diagnostic tools and systems for various heath related problems.
To encourage creative thinking and technology innovation, KAIST has been supporting HRHR (High Risk/ High Return) projects. We also have the EEWS funding to come up with major solutions for problems related to EEWS. KAIST faculty, staff and students should be encouraged to identify major problems that require technological innovations.
New KIs
In 2010, KAIST Institutes will consolidate, improve, and expand many of the programs we have initiated in 2009. We also hope to launch new multi-disciplinary units – the KAIST Institute for Theoretical Studies and the KAIST Institute for Brain Research. We should also consider closing down some of the existing KIs if they are no longer needed.
Globalization of KAIST Education
Other countries have approached us about transplanting our educational programs to their countries. This is in recognition of the fact that Korea’s rapid growth during the past three decades is in large part due to Korea’s high educational standards and strong universities.
Our new initiative with KUSTAR of Abu Dhabi should set an important milestone in expanding the global activities of KAIST and encouraging its growth.
Graduation Exercise
In February 2010, we are looking forward to holding graduation exercises in the new Sports Complex. This project was partially funded by Woori Bank and POSCO. This will surely reduce the anxiety level of Dean Kyung-Wook Paik, who is in charge of the graduation exercise, as in the past the Committee for Graduation Ceremony had to monitor the weather, as the ceremonies were held in KAIST’s outdoor amphitheater. We were fortunate that the weather cooperated the last few years, and we were pleased that President M.B. Lee delivered a memorable graduation address that was warmly received by our graduates and guests.
Construction
In May 2010, we will dedicate four new buildings, in addition to the Sports Complex: the Chunghi and BJ Park KI Building, the Pappalardo Medical Center, and the International Center. We are hoping that we will soon have a major donor for the Sports Complex as well.
We will also complete the new apartment complex for international faculty and two dormitories for students in 2010. These buildings will help in reduce the pressure for accommodation for faculty and students.
In 2010, KAIST will build several new buildings to accommodate new research and educational programs. We will build the Chung Moon-Soul Building II for Brain research and education, the Kim Byung-Ho IT Building, Animal Facility, and a new Natural Science Building. These buildings should be ready for occupancy in 2011. The new Kim Byung-Ho IT Convergence Center should incorporate futuristic IT technologies.
Several of our old buildings were built more than 20 years ago. They are in urgent need of complete remodeling and renovation. We are hoping to convince the government that these buildings should be completely renovated to reduce the endless repair costs that are currently being incurred to maintain the minimal functions of the buildings. The cost of the renovation is estimated to be 80 billion won.
Academic Programs by Colleges and Departments
Departments, colleges and programs have developed their own plans for 2010, which are attached to this report. These plans will be refined in 2010 once we have a firm budget from the government.
Finance and Budget
In the past, without a full-time CFO, KAIST’s sizable finances were challenging to administer. On January 1, 2010, Mr. Cho, Koog-Jun, with his deep experience in finance and banking, will become the first CFO of KAIST. He will oversee all aspects of finance, including the budget, outsourcing, and expenses associated with major projects.
A major concern for KAIST is the future of its government support. KAIST’s budget increased during the past three years because of the special funding of special projects such as the Globalization Project, the EEWS program, the WCU program, the OLEV Project, and the MH Project. However, KAIST’s base budget has not increased at a rate commensurate with its successful educational and research programs. In order to achieve its goals, KAIST must receive substantial increases in its base budget in the future.
Issues Related to Faculty
Our Five-Year Plan was based on the idea that the number of KAIST’s tenure-track faculty would grow to about 700, so that KAIST can be competitive with the best universities in the world. In the past three years, 150 new professors joined our faculty. Even with the merger of ICU and KAIST, we now have only about 550 tenure-track faculty members, far short of where we should be. During the next 10 years, about 34% of the faculty will retire, and in 15 years, about 54% of the faculty will retire. This high retirement number is a result of the faculty’s skewed age distribution, caused by the merger of relatively new institutions, i.e., KAIS, KIT, and ICU.
To overcome the problems associated with this loss of faculty, we must do the following two things: (a) extend the retirement age of some key faculty members and (b) add many more young professors and eminent scholars to the ranks of our faculty. Our current thinking is that we should extend the retirement age of about 15% of our faculty members to age 70, but careful planning is necessary to implement such a policy.
Sejong City
In January 2009 (well before the current controversy surrounding the relocation of the government), KAIST and the government signed an MOU, which stipulates that KAIST will purchase 490 thousand Pyung of land in Sejong City. Our plan is to establish a Research Hospital, the College of Life Science and Bioengineering, the Graduate School of Public Policy for Science and Technology, Research Centers for Green Technologies (OLEV, MH, and EEWS), an Apartment Complex for Faculty and Staff (for purchase), and a Convention Center for International Conferences. The government agency in charge of developing the city will be installing OLEV bus lines in the city.
The land we have agreed to purchase is adjacent to the widest section of Guem Gang River. It is a prime piece of real estate. KAIST will be able to establish a beautiful campus there, where our students and faculty can enjoy nature while pursuing scholarly and educational activities.
K-12 Education
As we recruit more faculty and staff from abroad, secondary education for their children will become an issue that must be addressed. Because an acceptable agreement with a local international school could not be arranged, we have decided to establish a K-12 school on the ICC campus. We hope to incorporate the school in 2010 and to begin to teach in 2011. Our K-12 school will be similar to the one started by Handong University.
We wish everyone a Happy New Year!
