New KAA President Chilhee Chung Calls Alumni Engagement a Top Priority
The KAIST Alumni Association (KAA) inaugurated Advisor Chilhee Chung of Samsung Electronics as its new president. President Chung was preceded by Ki-Chul Cha, the CEO of Inbody Co. Ltd. His term as the 25th president starts from February 2020 and ends in January 2022. President Chung received his master’s degree from KAIST's Department of Physics in 1979 and joined Samsung Electronics the same year. He also holds a doctorate in physics from Michigan State University in the United States. President Chung devoted himself to helping Samsung Electronics and Korea's system semiconductor and memory device technologies achieve global dominance for more than 40 years. He led future technology development at Samsung Electronics in the fields of quantum dot and neural processing from various leadership positions, including the head of the Semiconductor R&D Center, and the president of Samsung Advanced Institute of Technology (SAIT). President Chung is currently an advisor to SAIT, a member of the Presidential Advisory Council on Science and Technology (PACST), and the chairman of the 2045 National Future Strategy Committee and the Nano Technology Research Association (NTRA). President Chung said, “KAIST, throughout its history of half a century, has been working tirelessly to become the world’s best, beyond being the best in Korea. We, the alumni of KAIST, have the commensurate duty as well as the privilege of being proud members of KAIST, as the university's global stature grows.” “Recently, 46 alumni made 535 million won in donations, and established a scholarship to encourage entrepreneurial spirit in members of the KAIST community. This fund was dedicated to supporting 30 alumni entrepreneurs and students participating in the International Consumer Electronics Show (CES) 2020 that was held in Las Vegas last month. Moreover, another alumnus of ours Byeong-Gyu Chang, the CSO of the KRAFTON Inc., donated 10 billion won to KAIST in hopes of opening up more opportunities that may lead KAIST students to success. Mr. Chang’s donation is by far the largest that has been made by KAIST alumni.

More than 900 alumni, including President Sung-Chul Shin who is also an alumnus of KAIST, gathered in Seoul on January 18 to celebrate the New Year and the newly-elected leadership of the KAA. (END)
Algorithm Identifies Optimal Pairs for Composing Metal-Organic Frameworks
The integration of metal-organic frameworks (MOFs) and other metal nanoparticles has increasingly led to the creation of new multifunctional materials. Many researchers have integrated MOFs with other classes of materials to produce new structures with synergetic properties. Despite there being over 70,000 collections of synthesized MOFs that can be used as building blocks, the precise nature of the interaction and the bonding at the interface between the two materials still remains unknown. The question is how to sort out the right matching pairs out of 70,000 MOFs. An algorithmic study published in Nature Communications by a KAIST research team presents a clue for finding the perfect pairs. The team, led by Professor Ji-Han Kim from the Department of Chemical and Biomolecular Engineering, developed a joint computational and experimental approach to rationally design MOF@MOFs, a composite of MOFs where an MOF is grown on a different MOF. Professor Kim’s team, in collaboration with UNIST, noted that the metal node of one MOF can coordinately bond with the linker of a different MOF and the precisely matched interface configurations at atomic and molecular levels can enhance the likelihood of synthesizing MOF@MOFs. They screened thousands of MOFs and identified optimal MOF pairs that can seamlessly connect to one another by taking advantage of the fact that the metal node of one MOF can form coordination bonds with the linkers of the second MOF. Six pairs predicted from the computational algorithm successfully grew into single crystals. This computational workflow can readily extend into other classes of materials and can lead to the rapid exploration of the composite MOFs arena for accelerated materials development. Even more, the workflow can enhance the likelihood of synthesizing MOF@MOFs in the form of large single crystals, and thereby demonstrated the utility of rationally designing the MOF@MOFs. This study is the first algorithm for predicting the synthesis of composite MOFs, to the best of their knowledge. Professor Kim said, “The number of predicted pairs can increase even more with the more general 2D lattice matching, and it is worth investigating in the future.” This study was supported by Samsung Research Funding & Incubation Center of Samsung Electronics.

KAIST Develops Analog Memristive Synapses for Neuromorphic Chips
(Professor Sung-Yool Choi from the School of Electrical Engineering) A KAIST research team developed a technology that makes a transition of the operation mode of flexible memristors to synaptic analog switching by reducing the size of the formed filament. Through this technology, memristors can extend their role to memristive synapses for neuromorphic chips, which will lead to developing soft neuromorphic intelligent systems. Brain-inspired neuromorphic chips have been gaining a great deal of attention for reducing the power consumption and integrating data processing, compared to conventional semiconductor chips. Similarly, memristors are known to be the most suitable candidate for making a crossbar array which is the most efficient architecture for realizing hardware-based artificial neural network (ANN) inside a neuromorphic chip. A hardware-based ANN consists of a neuron circuit and synapse elements, the connecting pieces. In the neuromorphic system, the synaptic weight, which represents the connection strength between neurons, should be stored and updated as the type of analog data at each synapse. However, most memristors have digital characteristics suitable for nonvolatile memory. These characteristics put a limitation on the analog operation of the memristors, which makes it difficult to apply them to synaptic devices. Professor Sung-Yool Choi from the School of Electrical Engineering and his team fabricated a flexible polymer memristor on a plastic substrate, and found that changing the size of the conductive metal filaments formed inside the device on the scale of metal atoms can make a transition of the memristor behavior from digital to analog. Using this phenomenon, the team developed flexible memristor-based electronic synapses, which can continuously and linearly update synaptic weight, and operate under mechanical deformations such as bending. The team confirmed that the ANN based on these memristor synapses can effectively classify person’s facial images even when they were damaged. This research demonstrated the possibility of a neuromorphic chip that can efficiently recognize faces, numbers, and objects. Professor Choi said, “We found the principles underlying the transition from digital to analog operation of the memristors. I believe that this research paves the way for applying various memristors to either digital memory or electronic synapses, and will accelerate the development of a high-performing neuromorphic chip.” In a joint research project with Professor Sung Gap Im (KAIST) and Professor V. P. Dravid (Northwestern University), this study was led by Dr. Byung Chul Jang (Samsung Electronics), Dr. Sungkyu Kim (Northwestern University) and Dr. Sang Yoon Yang (KAIST), and was published online in Nano Letters (10.1021/acs.nanolett.8b04023) on January 4, 2019.

First Female Grand Prize Awardee of Samsung Humantech
Yeunhee Huh, PhD candidate (Professor Gyu-Hyeong Cho) from the School of Electrical Engineering received the grand prize of the 24th Humantech Paper Award. She is the first female recipient of this prize since its establishment in 1994. The Humantech Paper Award is hosted by Samsung Electronics and sponsored by the Ministry of Science and ICT with JoongAng Daily Newspaper. Her paper is titled, ‘A Hybrid Structure Dual-Path Step-Down Converter with 96.2％ Peak Efficiency using 250mΩ Large-DCR Inductor’. Electronic devices require numerous chips and have a power converter to supply energy adequately. She proposed a new structure to enhance energy efficiency by combining inductors and capacitors. Enhancing energy efficiency can reduce energy loss, which prolongs battery hours and solves overheating of devices; for instance, energy loss leads to the overheating issue affecting phone chargers. This technology can be applied to various electronic devices, such as cell phones, laptops, and drones. Huh said, “Power has to go up in order to meet customers’ needs; however the overheating problem emerges during this process. This problem affects surrounding circuits and causes other issues, such as malfunctions of electronic devices. This technology may vary according to the conditions, but it can enhance energy efficiency up to 4%.”During the ceremony, about eight hundred million KRW worth cash prizes was conferred to 119 papers. KAIST (44 papers) and Gyeonggi Science High School (6 papers) received special awards given to the schools.

Master of Science in Intellectual Property: First Class Starts on Saturday, February 6, 2010
Newly Established, Postgraduate Course for Master of Science in Intellectual Property First class starts on February 6th, 2010 In conjunction with Korean Intellectual Property Office (KIPO), KAIST has established a new postgraduate course for a master of science in intellectual property (IP). 41 students have enrolled the course, and its first class will begin February 6th, 2010. With a diverse professional background, the first-year students came from private businesses, IP service industry, and public organizations. Globally well-known companies—Samsung Electronics, LG Electronics, and the Pohang Iron and Steel Company (POSCO)—and mid-sized companies have offered scholarships to support the new M.S. Program. Business and industry in Korea have recognized the increasingly important role of intellectual property in a modern economy and showed a strong interest in developing workforce specialized in subjects such as, but not limited to, patent law, copyright and designs law, trade mark law, unfair competition, anti-trust law, competition law, and trade secret law. Prosecutor Chan-Gi Na from Seoul Central District Prosecutor’s Office said, “I’ve applied for the master program at KAIST because I wanted to learn more about intellectual property in greater depth. Through the coursework, I hope to enhance my knowledge on the subjects and use it for the protection of Koreans’ IP related rights and the development of our nation’s IP industry.” Assistant Manager Jin-Hong Bae from Samsung Securities, Inc. said, “Since the capital market law becomes effective, the need for developing new financial products or services in our finance market has rapidly grown. We no longer can make our financial products by simply copying or ripping off ideas from others. It’s a must practice, not an option, to set up a system under which we are able to protect our IPs.” “I would like to become an expert in our finance market, who really knows how to commercialize intellectual property assets into benefits, so any know-hows or ideas accumulated from years of working in the field can be registered and protected,” added Mr. Bae. KAIST’s Mater Program for intellectual property is designed for engineers who wish to acquire the skills required to play a leading role in the field. These engineers, KAIST anticipates, will establish and execute business strategies to protect intellectual property, generate added values for a company, and effectively respond against patent related claims. The intellectual property will seize up to 90% of business values to be generated in the 21st century. KAIST has long foreseen the need for training top-notch engineers in intellectual property. Combined with multidisciplinary approach to engineering, law, and management, the new M.S. Program will provide students with a variety form of classes to assist them in getting a practical knowledge as needed based on their interests and career aspirations. Examples of the classes are workshops on the change in technology trends—i.e., information technology (IT), environmental technology (ET), and bio technology (BT); standardization of intellectual property and value assessment; and patent law related claims. “All professors involved in the course are experts who are equipped with hands-on experiences in working on intellectual property for a long time at government agencies, companies, and law firms,” Professor Chul-Ho Kim, responsible for overseeing the entire program, said. He also expressed his confidence that “We have set up an academic system to induct highly qualified professionals and engineers, capable of handling all aspects of intellectual property related issues, into work places. Our coursework encompasses technology, research and development (R&D), and management, and students who complete the program will be ready to tackle down any intellectual property matters in the 21st century.” Freshmen convocation for the IP M.S. Program is scheduled on February 20th at KAIST, and President Nam Pyo Suh and Commissioner Jung-Sik Koh of Korean Intellectual Property (KIPO) will attend the event.
