What Guides Habitual Seeking Behavior Explained
A new role of the ventral striatum explains habitual seeking behavior Researchers have been investigating how the brain controls habitual seeking behaviors such as addiction. A recent study by Professor Sue-Hyun Lee from the Department of Bio and Brain Engineering revealed that a long-term value memory maintained in the ventral striatum in the brain is a neural basis of our habitual seeking behavior. This research was conducted in collaboration with the research team lead by Professor Hyoung F. Kim from Seoul National University. Given that addictive behavior is deemed a habitual one, this research provides new insights for developing therapeutic interventions for addiction. Habitual seeking behavior involves strong stimulus responses, mostly rapid and automatic ones. The ventral striatum in the brain has been thought to be important for value learning and addictive behaviors. However, it was unclear if the ventral striatum processes and retains long-term memories that guide habitual seeking. Professor Lee’s team reported a new role of the human ventral striatum where long-term memory of high-valued objects are retained as a single representation and may be used to evaluate visual stimuli automatically to guide habitual behavior. “Our findings propose a role of the ventral striatum as a director that guides habitual behavior with the script of value information written in the past,” said Professor Lee. The research team investigated whether learned values were retained in the ventral striatum while the subjects passively viewed previously learned objects in the absence of any immediate outcome. Neural responses in the ventral striatum during the incidental perception of learned objects were examined using fMRI and single-unit recording. The study found significant value discrimination responses in the ventral striatum after learning and a retention period of several days. Moreover, the similarity of neural representations for good objects increased after learning, an outcome positively correlated with the habitual seeking response for good objects. “These findings suggest that the ventral striatum plays a role in automatic evaluations of objects based on the neural representation of positive values retained since learning, to guide habitual seeking behaviors,” explained Professor Lee. “We will fully investigate the function of different parts of the entire basal ganglia including the ventral striatum. We also expect that this understanding may lead to the development of better treatment for mental illnesses related to habitual behaviors or addiction problems.” This study, supported by the National Research Foundation of Korea, was reported at Nature Communications (https://doi.org/10.1038/s41467-021-22335-5.) -ProfileProfessor Sue-Hyun LeeDepartment of Bio and Brain EngineeringMemory and Cognition Laboratoryhttp://memory.kaist.ac.kr/lecture KAIST

KAIST Undergraduate Students Volunteer in Ethiopia
World Friends (WF), one of the undergraduate student clubs at KAIST, offer students opportunities to volunteer in underdeveloped regions and countries. This year the World Friends team travels to Ethiopia from July 9 to August 17, 2015. The aim of this trip is to help Ethiopian students fill gaps in their knowledge of information technology and encourage KAIST students build leadership skills through volunteer activities. Twenty-eight students will make the trip. KAIST students will visit the Addis Ababa Institute of Technology and the Adama Science and Technology University, as well as some local high and elementary schools in Addis Ababa, where they will run computer classes related to the basics of information technology such as C Language, Java Programming, Photoshop, MS Office, and Windows. The volunteers will offer Adama Science and Technology University students an advanced computer course to prepare them to participate in the ACM-ICPC, an international computer programming competition for university students. KAIST students will also introduce Korean culture to Ethiopian students including K-pop, Korean cuisine and fashion, Korean language lessons, and traditional Korean art. The Dean of Student Affairs and Policy at KAIST, Professor Young-Hee Kim said, “I hope the students from two very different cultures will cherish this opportunity to interact with each other and contribute to narrowing down the regional disparities in the IT field.”
An Exploratory Study on Smartphone Abuse among College Students
Professor Uichin Lee Professor Uichin Lee of the Department of Knowledge Service Engineering, KAIST, and his research team developed a system that automatically diagnoses the levels of smartphone addiction based on an analysis of smartphone use records. Professor Lee investigated the usage patterns of 95 smartphone users (college students) by conducting surveys and interviews and collecting logged data. The research team divided participants into “risk” and “non-risk” groups based on a self-reported rating scale to evaluate their abuse of smartphones. As a result, 36 students were categorized as “high risk” and 59 were categorized as “low risk.” The researchers collected over 50,000 hours of smartphone use encompassing power levels, screen, battery status, application use, internet use, calling, and texting. The results showed that the “high risk” group used only 1~2 applications, focusing on mobile messengers (Kakotalk, etc.) and SNS (Facebook, etc.). In addition, a relationship was found between alarm function and addiction levels. Users who set alarms for Kakaotalk messages and SNS comments used smartphones for an additional 38 minutes per day on average. Results also showed that “high risk” students were on their smartphones for 4 hours and 13 minutes per day, 46 minutes longer than “low risk” students who used smartphones for 3 hours and 27 minutes. The difference was prevalent during 6 am and noon, and 6pm and midnight. In addition, “high risk” students accessed their smartphones 11.4 times more than “low risk” students. Based on the collected data, Professor Lee developed an automatic system that distinguished users into “high risk” or “low risk” categories with 80% accuracy. The new system is expected to give an early diagnosis of addiction to smartphone users, thereby allowing for early treatment and intervention before the user becomes addicted. Professor Lee commented that, "the conventional addiction analysis based on self-analysis surveys did not provide real-time data and were largely inaccurate. The new system overcomes these limitations through data science and personal big data analysis" and that he is "developing an application that monitors smartphone abuse." Figure 1.

President Lee Myung-bak's Congratulatory Address at 2009 KAIST Commencement Ceremony
Following is the full text of President Lee Myung-bak"s congratulatory address at the 2009 KAIST Commencement Ceremony. Beloved graduates, proud parents, dear family members, Mr. Cho Jeong-nam, Chairman of the Board of Directors, Dr. Suh Nam-pyo, President of KAIST, Esteemed faculty and staff members, Distinguished guests, ladies and gentlemen, It is great to see you all. First of all, I must begin by extending my most sincere congratulations to the 1,976 graduates who are receiving their degrees today. You worked hard, you earned it and I congratulate you. We must also remember your parents who worked just as hard as you did, if not more, to support you. You may have family members whom you wish to thank for their support and understanding. I also thank and congratulate the faculty and staff members who worked hard to provide the best possible education for you. Today is also a great day since we can all join together to recognize the achievements of Dr. Ryu Geun-chul and show him how deeply we respect and appreciate his generous contributions to KAIST. Today, Dr. Ryu received an honorary doctorate in science for his life-long contributions in the field of Korean traditional medicine. He has also donated a vast portion of his personal wealth to KAIST for educating future leaders in science and technology. Dear graduates, faculty members, KAIST has been in the forefront of leading Korea’s development over the last thirty-eight years. As the preeminent institution devoted to educating the very best minds in science and technology, more than 20% of all doctorate degree holders in Korea’s science and engineering field are KAIST alumnus. KAIST has led the drive to create more than 470 venture start-ups, opening up a vast new horizon for Korea’s scientific and technological breakthrough while leading the economic growth of Korea. KAIST has done exceptionally well even compared to the world’s best. It is ranked 34th in engineering and IT. It is ranked 46th in natural sciences. These rankings are a demonstration that KAIST is a research-focused institution with global competitiveness. Moreover, KAIST has been an example for other higher institutions seeking to reform the way colleges and universities operate. KAIST has demonstrated its forward-looking and reform-minded vision in terms of selecting students, recruiting and evaluating professors and managing its courses. In particular, when KAIST selects its students, it doesn’t look only at their test scores but looks for creative and innovative minds with real character and potential. Such practices are having positive influences on how other universities and colleges select their students. Furthermore, KAIST has taken the lead in applying their research skills to matters of global concern through its EEWS initiative. I am proud of such visionary work and will continue to have high hopes for KAIST. Our promising future depends on gifted individuals and gifted individuals are nurtured through solid education. For a country such as Korea with no natural resources, human capital is our greatest and most precious resource. We must overcome our lack of natural resources with our abundant and limitless brain power. The 21st century will be a knowledge-based society and so national competitiveness of individual countries will be determined by how competitive its universities and research institutes are. And the time calls for universities with world-class capabilities in research. Especially, our investments in science and technology today will ensure a brighter tomorrow. I assure you that this government will spare no effort to KAIST so that it can continue to foster the best minds for even greater achievements. My dear graduates and professors, proud parents and family members, All of us are going through difficult times due to the global economic crisis. At the same time, we must face global climate change which is our common concern. And this global concern must not be put aside or given less priority because of the economic crisis. We must do all we can to overcome the economic crisis while aggressively and consistently implementing measures to deal with climate change. At the same time, we must continue our quest to develop the next-generation engines of growth in preparation for the future when this economic crisis is eventually over. This is killing three birds with one stone and this is the core of my Low Carbon/Green Growth vision for Korea’s future. For a country like Korea with no oil reserves whatsoever, Low Carbon/Green Growth is a must. We simply do not have any other choice. It is also the path that the global community must take. Korea was late in joining the club of industrialized countries but we are ahead in the information technology sector. But, because we did not possess the core technologies in information and communication, we were unable to fully benefit from being ahead. Now, we must excel in all areas in the age of green growth. Korea’s future growth will depend on how many core technologies we manage to accrue in green technology, such as technologies to conserve energy, development of new and renewable energy. The government will double, compared to last year, its investments into research and development of green technology. The government has a long-term vision and this vision calls for continuously increasing strategic investments into the new engines of growth and they include basic sciences, core technologies and big science. Deregulation will continue so that we can foster scientific and technological advancements and also attract more investments and people from abroad. Dear graduates, Another source of our new engine of growth and our green technology is none other than fusion technology. Our bio, IT and nano technology will come together, and coupled with what is already a world-class IT industry, we can create future engines of growth. President Suh Nam-pyo stressed that “Inter-disciplinary study that takes place amidst the boundaries of different disciplines is where new discoveries and added-value are found.” This is a reminder of the importance of fusion research. And we all know that KAIST is the leader in this endeavor. Fusion technology will greatly improve our quality of life and introduce new and innovative ways to solve our real concerns. Healthcare and medical science are just two examples. As our society becomes an aged society, identifying the causes of and finding the cure for degenerative diseases such as Pakinson’s and dementia are becoming more and more important. If we manage to successfully combine our knowledge in medicine, science and engineering, we can come up with revolutionary ways to detect and cure these and other diseases. In particular, we will soon see science and medicine come together to create an entirely new paradigm in how we take care of our health. Medicinal research and high-tech research hospitals will be the norm. I truly believe that we can save both this planet as well as ourselves by utilizing green technologies and high-tech fusion technology. The government will continue to support such efforts. Dear graduates, the heroes of today, Some of you may wish to pursue higher degrees in order to reach even loftier academic goals. Some of you may opt to venture into society. Wherever you go and whatever you decide to do, do not be afraid of failure. Pursue your dreams. Face the challenges that come your way. And when you boldly face these challenges with the most precious gift you have, your youth and ideals, your dream will come true. Remember that history is made by those who take up the challenge. Do not be discouraged if you fail today. Just pick yourselves up tomorrow and try again. And again. Do not be consumed by selfish ambitions. But instead, always think what you can do for your society, your country and for humankind. Science and technology that is used for personal gains or new innovations and technologies lacking even the very basic ethical standards can become a curse to mankind. This is why those aspiring to become scientists and engineers must first agonize over how they plan to better the lives of man before they learn how to conduct experiments. Once you’ve gone through this, you will then be eligible to become true leaders, with your character and technological know-how. Remember the time you spent hunched over a book, in the classroom, in the library or in laboratories. Do not forget why you came here in the first place. Aim for higher goals in your respective fields. With that, I wish you a wondrous and exciting new journey. Again, congratulations and well done! Thank you.
KAIST Team Identifies Nano-scale Origin of Toughness in Rare Earth-added Silicon Carbide
A research team led by Prof. Do-Kyung Kim of the Department of Materials Science and Engineering of KAIST has identified the nano-scale origin of the toughness in rare-earth doped silicon carbide (RE-SiC), university sources said on Monday (Oct. 6). The research was conducted jointly with a U.S. team headed by Prof. R. O. Ritchie of the Department of Materials Science and Engineering, University of California, Berkeley. The findings were carried in the online edition of Nano Letters published by the American Chemical Association. Silicon carbide, a ceramic material known to be one of the hardest substances, are potential candidate materials for many ultrahigh-temperature structural applications. For example, if SiC, instead of metallic alloys, is used in gas-turbine engines for power generation and aerospace applications, operating temperatures of many hundred degrees higher can be obtained with a consequent dramatic increase in thermodynamic efficiency and reduced fuel consumption. However, the use of such ceramic materials has so far been severely limited since the origin of the toughness in RE-SiC remained unknown thus far. In order to investigate the origin of the toughness in RE-SiC, the researchers attempted to examine the mechanistic nature of the cracking events, which they found to occur precisely along the interface between SiC grains and the nano-scale grain-boundary phase, by using ultrahigh-resolution transmission electron microscopy and atomic-scale spectroscopy. The research found that for optimal toughness, the relative elastic modulus across the grain-boundary phase and the interfacial fracture toughness are the most critical material parameters; both can be altered with appropriate choice of rare-earth elements. In addition to identifying the nano-scale origin of the toughness in RE-SiC, the findings also contributed to precisely predicting how the use of various rare-earth elements lead to difference in toughness. University sources said that the findings will significantly advance the date when RE-SiC will replace metallic alloys in gas-turbine engines for power generation and aerospace applications.

KAIST Students Wins Gold Prize at Technical Idea Contest
KAIST Students Wins Gold Prize at Technical Idea Contest - Receive the gold prize at the 3rd High-Tech Daejeon Technical Idea Contest for Company Establishment- For the development of a new system to convert complex web page addresses to short and meaningful addresses Sang-Hoon Kim, Song-Hwa Chae and Dong-Hun Lee of Chemical and Biomolecular Engineering won the gold prize at the prospective company establishment part in the 3rd High-Tech Daejeon Technical Idea Contest for Company Establishment on May 21 for their valuable development of ‘Web Page Address Clipping System’. So far, simplified web page addresses include special characters, which make the addresses long and complex. That is, the current address simplification service combines meaningless random words and numerals to create addresses when web page addresses are entered. In this case, the addresses are not easy to share with others and reuse several times since they are difficult to memorize. However, the ‘Web Page Address Clipping System’ shortens meaningless long addresses. In addition, the improved address simplification service will provide user’s own addresses, and statistics and ranking to clipping addresses frequently used. Based on this technology, Kim and Chae are now preparing to open a company called ‘URLClip’ under the auspice of Professor Tae-Yong Yang and Researcher In-Soo Kim, KAIST Entrepreneurship Center. They are also expanding their service areas onto clipping library for individual users, host name services for enterprises, etc. and developing tool bar, RSS service (RSS is an acronym of RDF (or Rich) Site Summary. It refers to a service that automatically and easily provides frequently updated contents such as news and blogs to users), etc. to improve users’ conveniences.
