[Academics][Excellent R&D] The Institute for Knowledge Services Selected as a Pivotal Laboratory

Each year, the National Research Foundation of Korea selects the ‘pivotal’ university laboratories to support the research of national value. This year, the Institute for Knowledge Services (IKS) of ERICA Campus was given the honor of becoming a pivotal laboratory. They will receive governmental support of 200 million won annually for three years, up to six years. IKS has conducted many notable studies on services of knowledge, and their current research topic, the ‘IC-PBL Education Method for leading consultants of middle and small-sized companies in the Fourth Industrial Revolution’ aims to strengthen one of the primary fields of knowledge services -- business consulting. Specifically, the aim is to design an education method to grow competent consultants, targeting Korea’s middle and small-sized companies in the era of the Fourth Industrial Revolution. The head of IKS is Professor Hwang Seung-june (Division of Business Administration, ERICA Campus). Professor Hwang Seung-june (Division of Business Administration, ERICA Campus) and his Institute for Knowledge Services of Hanyang's ERICA Campus was recently selected by the National Research Foundation of Korea as a ‘pivotal' university research laboratory. “One of the weaknesses of Korea is in the service of knowledge,” said Hwang. “A prime example of that weakness shows in the domain of business consultation.” Hwang pointed out that there are critical limitations in Korea’s current education of business administration. Most case studies are based on large foreign companies. Moreover, education is theory-based and outdated. In order to address this problem, Hwang suggested IC-PBL as the most suitable education model. “We are implementing IC-PBL as the main class model.” IC-PBL (Industry-Coupled Problem-Based Learning) is Hanyang’s own experimentative class method which focuses on practical problem-solving exercises using real-life issues. The class will be conducted through five steps: on the first week, a company’s personnel will explain the actual problem the company is currently experiencing. Then, students will first comprehend and analyze the situation, define the problem, name the root cause, provide a solution, and implement the solution. The results will receive feedback from the company’s personnel. His proposal of such a class model is significant, not only because it addresses the problem of current Korean service of knowledge, but also because, as Hwang emphasized, there is a need to grow powerful domestic business consultants and consulting knowledge that could be implemented on Korea’s small and medium-sized companies. Also, with the Fourth Industrial Revolution, a new model of business consultation that handles big data and AI effectively is in demand. In order to achieve this, a practical analysis of on-site cases is necessary. The Institute for Knowledge Services has conducted many notable studies on services of knowledge. With their latest research, they aim to develop powerful Korean business consultants. Hwang said that starting next semester, this education model will be implemented on Management Consulting post graduate school. The fields of industries will vary each class and each semester, including food, automobile, and service companies. Students of each class will experiment with drawing their own solutions using big data or AI analysis, paving their way to becoming a competent business consultant. "Our ultimate goal is to come up with a new, practical Korean business consultant model for small and medium-sized companies, and disseminate that knowledge,” said Hwang.

[Academics][Researcher of the Month] Highly Sensitive, Power Efficient H2 and H2S Gas Sensors Adoptable to Mobile Forms

Professor Choa Yong-Ho (Department of Materials Science and Chemical Engineering) has written a thesis titled, "Facile tilted sputtering process (TSP) for enhanced H2S gas response over selectively loading Pt nanoparticles on SnO2 thin films," which depicts the development of highly sensitive gas sensors that are driven by ultra low power (ULP). Having began the research with the development of gas sensors of various mechanisms through the syntheses of gas inductors in 2010, it was developed through the Fundamental R&D Program for Core Technology of Materials and the NanoMaterial Technology Development Program hosted by the Ministry of Trade, Industry and Energy, and the National Research Foundation of Korea (NRF). Around 10 patents were registered, and some portion of the technology was transferred to Gastron. Professor Choa Yong-Ho (Department of Materials Science and Chemical Engineering) anticipates the development of various gas sensors including hydrogen and hydrogen sulfide sensors to apply to real life. A typical gas sensor has a heater built in in order to increase its sensing capabilities. However, this has resulted in an increase in power consumption that has limited mobile application and the manufacturing of small sized gas sensors. The research team led by Choa developed ultra low power gas sensors driven in room temperature of 25C, which satisfies the rising need of ultra low power, as well as highly sensitive hydrogen (H2) and hydrogen sulfide (H2S) gas sensors. While the use of natural gas is increasing day by day, the current state of homes and industrial settings are increasingly prone to gas explosion and pollution. Methods such as the ability to sense gas leakage, the ability to measure and record gas concentration, the recognition of it, and the ability to control and warn of the various pollutants discharged from combustion apparatus are in dire need as of now -- since it is impossible to detect or distinguish the type of gas or the dangers that they entail through only the human sensory organs. H2S gases are generated as a by-product of a petroleum purification process or in the manufacturing processes of glue, leather, and raw fluorescent material. The gas sensor that detects hydrogen sulfide can stop the interior breathing of cells, paralyze central nerves, and show symptoms of asphyxiation, due to its strong toxicity. Therefore, H2S gas requires successive monitoring in order to achieve local industrial development and to create a safe atmosphere. The international world is responding by actively implementing regulations regarding industrial atmosphere control and pollution emissions. The following images (from left) are an integrated wireless smart sensor module, a gas detection graph, and the sensing graph on a mobile display. (Photo courtesy of Choa) In addition, the world is rapidly shifting its focus to hydrogen energy as our interest for low-pollution alternative energy is on the rise, along with the growing concern for environmental pollution and exhaustion of fossil energy. However, hydrogen has drawbacks in itself in that it goes through spontaneous combustion or explosion when combined with oxygen in the air. Until a system is developed, hydrogen fuel can only be widely used when the system promptly detects the leakage of hydrogen and prevents the outflow of it in the first place by devising a safety measure in the production, storage, and usage of hydrogen. Choa’s research team have created a chemical resistance sensor that changes according to gas concentration, as well as a thermochemistry sensor that selectively reacts to target gas to generate heat in the reaction and applies this to the sensing. The thermochemistry sensor has the benefit of minimizing power consumption thanks to its form which signals itself generating voltage.

[Academics][HYU Research] Develops Self-Powered Artificial Muscle

* This article is published in 2019 Hanyang Research Magazine Vol.2 Professor Kim Seon-jeong Develops Self-Powered Artificial Muscle The development of artificial joints or skeletons is highly regarded as a technology for a healthy life, which human nature is longing for. In the midst of this, researches are actively underway to create even muscles, which are one of the largest components in human body, with the artificial technology. In 2017, professor Kim Seon-jeong of Hanyang University, Division of Electrical and Biomedical Engineering and eight teams from three countries have succeeded in developing the world's first artificial muscle energy harvester (regenerating electrical energy from an energy that is thrown away in nature). Professor Kim's research was consecutively selected for Creative Research Initiative Program, supported by Ministry of Science and ICT and National Research Foundation of Korea to foster world-class researchers in 2006 and 2015. As a result, artificial muscles with advanced materials and energy storage devices which stores an electrical energy for driving the artificial muscles have been developed and published four times in Science since 2011. The fifth article is also an extension of the ongoing research on artificial muscles. He further developed a self-powered emergency signal device (product name: Self-Powered Emergency Signal Device), which had the honor of winning the Innovation Award at 2019 CES. Professor Kim said, “From 2006 to 2015, we published numerous papers regarding to the artificial muscles as a Center for BioArtificial Muscle, and we are continuing to conduct research on electrical energy that can move the artificial muscles as a Center for Self-Powered Actuation.” also added that, “The technology of harvesting the electric energy from artificial muscle was selected for one of Korea's top 10 technologies news in 2017.” After 15 years in research, succeeding in developing artificial muscles that are more powerful than human muscles up to 40 times, he is now focusing on an energy that could actuate the artificial muscles. “As human muscles produce energy themselves to contract, artificial muscles need energy to move freely. We are studying yarn-type artificial muscles that can generate electricity while moving on their own on the basis of biomimetic engineering.” said professor Kim to introduce his research activities. According to Kim’s explanation, the generated energy from artificial muscles can not only move artificial muscles, but also replace conventional batteries. Batteries have good performance, however, they have disadvantages of discharging quickly and being useless in extreme environments such as in low temperatures or underwater. However, this yarntype harvester is not affected by these environments and expected to be utilized in various industries. Currently, the research is being conducted with professor Kim Seon-jeong, University of Texas in the United States and University of Wollongong in Australia, and they are recognized as the world’s top group in the fields. "We don’t have many researchers in the group, but they are elite. We want students to have a challenging spirit by presenting them with research interesting subjects,” said professor Kim at the end of the interview. “Teaching by rote has its limitations, so you have to be interested in, passionate and active to be effective,” said Kim to the students.

[Academics][HYU Research] Develops 5G Center into 5G/Unmanned Vehicle Research Development Center

* This article is published in 2019 Hanyang Research Magazine Vol.2 Professor Kim Sun-woo, Electronic Engineering Develops 5G Center into 5G/Unmanned Vehicle Research Development Center As South Korea succeeded in commercializing the world’s first 5G technology in early April, expectations that growth in various fields utilizing the technology are growing. Professor Kim Sun-woo (Department of Electronic Engineering) of Hanyang University is continuing his research to make this expectation a reality at the 5G/Unmanned Vehicle Convergence Technology Research Center which opened on campus in 2017. Realizing the importance of 5G technology and unmanned vehicles rather early, Hanyang University established the 5G/Unmanned Vehicle Convergence Technology Research Center in the fall of 2017 to foster the development of human resources in the areas of 5G and unmanned vehicles such as self-driving cars and drones with 4.5 billion KRW in subsidies from the Ministry of Science and ICT. Hanyang University, Seoul National University, Ajou University, and 11 companies including Contela, AM Telecom, Renault Samsung Motors, UVify, Geo Plan, Robowell Korea, InfoWorks, Funzin, Ascen Korea, and Essys will form a consortium to establish a research center. This research center is expected to be operational by 2022. The research center develops software and hardware through applied mathematics-based research. It requires global competitiveness, high-quality programming skills, and it will last up to six years. Kim said, “As well as building a solid foundation, we are conducting research in conjunction with talented researchers from around the world.” Research centers are also actively conducting research on unmanned vehicles, including self-driving cars, Smart Cities, Internet of Things, and drones. Professor Kim predicts these will all be developed and used based on 5G technology. Kim is currently working on the research on 5G technology. In the past, communication technology was used only for communicating or transmitting data, but it will be extended to communication between objects in the future. Therefore, this core technology is the basis for autonomous vehicles, IoT technologies, and drones, that are drawing attention from various unmanned vehicles. “Development of 5G and unmanned vehicle source technology and developing human force are very important nationally,” Kim said. He added, “Hanyang’s research center is playing a big role enhancing the status of the university.” In addition, he said, “We will continue to cultivate great talents for the rapidly changing telecommunications sector such as 5G and 6G in the future. We are constantly working on distinguished research programs for our students." Meanwhile, in April, Professor Kim was invited to the ICT Future Talent Forum 2019 held at COEX in Samsungdong. It featured ‘Unmanned vehicle’s cooperative positioning and autonomous driving', 'Drone cluster flight assistance object recognition demonstration', 'CHEM VR LIBRARY', ' Cinematic VR <Confession>', ' ‘Object recognition video', ' Hybrid V2X terminal', and etc. Professor Kim said, “We were able to exchange research topics and technology trends from each university's ICT research center. The exhibition allowed us to check the research conducted at the center and cultivate the researchers one step further.” Click to Read Hanyang Research 2019 Vol.2

[Academics][HYU Research] Contributes to the Advent of a "Hydrogen Economy" by Significantly Reducing the Catalyst Cost

* This article is published in 2019 Hanyang Research Magazine Vol.2 Professor Song Tae-seup, Energy Engineering Contributes to the Advent of a "Hydrogen Economy" by Significantly Reducing the Catalyst Cost The Paris Climate Change Agreement signed in 2015 in Paris, which will transform not only Korea’s but the world's energy market, took up the role of transforming existing fossil fuels into alternative energy. With the recent growing interest in hydrogen, it is quickly becoming a popular energy source, even to the extent that the current government has declared a “hydrogen economy.” Song Tae-seup of the Hanyang University Department of Energy Engineering research team developed the catalyst materials with high efficiency, low cost, and high durability in line with this trend. This is expected to accelerate the revitalization of the hydrogen economy by succeeding in lowering the production cost of hydrogen. The hydrothermal technique requires a catalyst to electrolyze water to separate the hydrogen and oxygen. Catalytic materials are Metal-Metalloid elements based on transition metals, and research is being actively conducted on them. Among those elements, the development of Metal-Metalloid materials including triple and quadruple elements has continuously been attempted in order to take advantage of the varying electronic levels of the transferred metal. There was a limit to forming a stable compound with existing technology. The Metal-Metalloid materials based on transition metals alone were not stable in the electrolyte due to the dissolution of the metal element. Professor Song Tae-seup of the Department of Energy Engineering solved this issue using Atomic Layer Deposition (ADL) technology. In addition, Professor Song proposed the possibility of reducing the cost of catalyst by up to 20 percent, by developing the world’s first catalyst surface partial amorphous technology and enhancing hydrogen generation efficiency to four times that of conventional noble metal based catalysts. Professor Song said, “The hydrogen economy consists of the production, storage, and transportation of hydrogen,” and explained the need for this research by saying, “Among them, hydrogen production is an important technology for activating the hydrogen economy”. In particular, the Moon Jae-in government announced the roadmap to revitalize the hydrogen economy in January and set specific goals such as a cost of only 3,000 won per kilogram of hydrogen and a total of 6.2 million hydrogen cars by 2040. Now reducing hydrogen production costs through hydroelectric systems has become an essential challenge. Currently, there are disadvantages in commercialization due to the expensive price of Green Hydrogen which is produced through hydrolysis and photoelectrolysis and costs 9,000-10,000 won per kilogram, which is more expensive than Grey Hydrogen which costs 1500-2000 won per kilogram and comes from a refinery or gas reforming process. Professor Song rearranged atoms on the surface of the catalyst that generate hydrogen to remedy these disadvantages. The main feature is that the surface of the transition metal used as the conventional catalyst is fluorinated. As a result, the chemical activity of the catalyst surface rose, and the hydrogen production reaction became more active. Not only did the chemical activity increase, but the physical activity did as well, so the charge to decompose hydrogen in water could be supplied more efficiently. Professor Song Tae-seup said, “The newly developed atomic rearrangement technology can be applied to various high value-added next generation energy devices such as batteries, fuel cells, and supercapacitors, as well as high- efficiency hydrogen generation catalysts,” and concluded by saying that they are the core source technologies that can contribute to the creation of new growth engines for our country.

[Academics][HYU Research] Approaches Cancer Treatment through the Convergence

* This article is published in 2019 Hanyang Research Magazine Vol.2 Professor Paek Eun-ok, Computer Science Approaches Cancer Treatment through the Convergence Thanks to recent developments of cancer treatments, there has been a marked improvement in patients’ prognoses. Nonetheless, the fear that cancer strikes in people is beyond that of other diseases. In response to this, Professor Paek Eun-ok (Department of Computer Science) of Hanyang University successfully built a foundation for a treatment plan for stomach cancer, a particularly aggressive type of the disease, by applying computer science technology to biomedical research. Having already been selected as the researcher of the month in April of 2015 for her research in linking genomics and computer science, Paek holds a pioneering position in the field, also being selected as a regular member of The National Academy of Engineering of Korea last year. Notably, she was again selected as the researcher of the month in recognition of her work in drawing up measures to diagnose early stomach cancer through research on proteogenomics in February. Early onset stomach cancer, which usually develops in people in their 30s and 40s, is expected to be impacted more heavily by genetic factors than environmental factors than other cancers. It is also difficult to detect since its cancer cells are small and widely spread (diffuse type) and is known to develop metastasis. To determine the cause of stomach cancer, genes have been usually analysis. Protein analyses paired with genetic material is also necessary for more precise classification. There can be genetic level and protein level analyses for cancer diagnosis as well as determining the cause of cancer, and Paek’s integrated analysis method (Proteogenomics) complements the information available from these two analyses and enables a deeper causation analysis. In Korea and abroad, however, protein research is still in its early stages and there is a lack of related software. Paek is working with foreign researchers in the Clinical Proteomic Tumor Analysis Consortium (CPTAC) under the National Institute of Health (NIH) to study the integrated analysis method (Proteogenomics) and develop algorithms for cancer treatment. In general, tissue cell experiments begin by collecting cell tissue, but when tissue cells are exposed to air, proteins in the cells are prone to denaturation. To overcome these difficulties and to facilitate research, Paek has been collaborating with a number of experts in various fields, including biology, chemistry, and medicine, who have been collaborating in protein research at the Korea Institute of Science and Technology (KIST), Korea University and National Cancer Center for more than a decade. To produce more reliable and accurate results, cancer tissues and healthy tissues from 80 actual patients were collected and analyzed over five years. It is difficult to assert its direct usefulness since it is still a basic study. However, it is highly meaningful that the obtained results allow multiple perspectives on various types of data related to stomach cancer simultaneously. Regarding this research, Paek explained that “the same early stomach cancer patients have varied causes of the disease, thus require personalized treatments because of different genes and proteins each person has,” and that “through this research, we will establish a software foundation that will eventually lead to more than four types of personalized cancer treatments.” Paek, who is also conducting research related to pancreatic cancer, one of the worst forms of cancer, said that “we need to conduct in-depth research with a comprehensive view, not limited to small data.” She also had some advice for students: “I want you to have a researcher’s attitude to objectively look at your subjects and study a wide range of different information.” Click to Read Hanyang Research 2019 Vol.2

[Academics][HYU Research] The Era of Sustainable Bioenergy Is Coming

* This article is published in 2019 Hanyang Research Magazine Vol.2 Professor Jeon Byong-hun, Earth Resources and Environmental Engineering The Era of Sustainable Bioenergy Is Coming The current climate crisis from the rapid increase in carbon emissions of modern society is recognized as a planet-wide problem that exceeds regional and national boundaries, and the global interest in the production of carbon-neutral renewable energy "from the various" sources such as wind, sunlight, and tide has been raised more than ever before. Meanwhile, research on biomass-based renewable energy has also been actively conducted in recent years. Prof. Jeon Byong-Hun (Department of Earth Resources and Environmental Engineering at Hanyang University) is a renowned expert in the international bioenergy research society. Prof. Jeon’s pioneering works have been primarily on biogas production by anaerobic co-digestion using various biomass sources such as FOG (Fat, oil and grease), and on liquid biofuels production from microalgal biomass to address the solution toward the global warming. Prof. Jeon stated that, “As marine dumping of organic wastes (e.g. sewage sludge, livestock manure and food waste) has been prohibited, careful attention in their alternative treatments was emphasized for simultaneous recovery of renewable bioenergy during the treatment process of biomass.” The conventional ways of treating organic waste biomass (e.g. incineration, landfill or compost) are limited in their energy recovery and usage. However, utilizing different wastes including FOG in anaerobic digestion can lead to high yield of methane as clean renewable energy while reducing the volume of organic waste. Furthermore, unlike other types of renewable energy, biofuels can not only be utilized for the production of electricity but also directly used for combustion in engines. A researcher in Jeon’s laboratory said “The anaerobic digestion research had been somewhat difficult due to the sanitary issues related to sampling and handling of sludges produced from domestic wastewater treatment process that is used for research, plus the biological complexity and sensitivity of the anaerobic microbes in them. But I find it worthwhile to conduct the research using difficult-to-treat organic wastes that contain number of organic wastes to produce useful renewable energy.” In the concluding remarks, Prof. Jeon said, “I have obtained B.S., M.S. & Ph.D. degrees from Hanyang University, and Pennsylvania State University, USA, in natural resources and environmental engineering so I have been participating in the converged research studies, and I wanted to solve social problems such as global warming through my research. I also wish that more people and the government will get to have more interest on the societal importance of renewable energy in the future and pay their attention on the commercialization of bioenergy production from various biomass.” Click to Read Hanyang Research 2019 Vol.2

[Academics][Researcher of the Month] RNA Discovery Brings Light to Curing Cancer and Brain Disease

Professor Nam Jin-wu (Department of Life Science) may have discovered a key ingredient to diagnosing and curing brain disease and cancer in his research published on September 13th in Nature Communications. Nam’s research has brought light to a phenomenon regarding messenger Ribonucleic acids (RNA), a type of polymeric molecule essential in various biological roles that transfers information from the genome (genetic material of an organism) into proteins by translation (the process in which ribosomes in the cytoplasm synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus). Professor Nam Jin-wu (Department of Life Science) shared his data-driven journey for a deeper understanding of human bodily functions. Nam was the first to discover that microRNAs (small non-coding RNA molecules) and UPF1s (regulator of nonsense transcripts 1) interact with each other and conduct “post-transcriptional or translational regulation” within cells, which can bring deeper understanding to the fundamentals of gene manifestation within cells. MicroRNAs contain around 22 nucleotides (basic building blocks of DNA) found in plants, animals and some viruses, that function in RNA silencing, which prevents the expression of a certain gene, and post-transcriptional regulation of gene expression. UPF1 is a protein that in humans is encoded by the UPF1 gene and is known to be an important factor needed to selectively recognize incorrectly generated RNAs within cells and degrade them. The conversion process of DNA to protein (Photo courtesy of www.kurzweilai.net) There are many ways to regulate the process of making protein from DNA genes within cells in the human body. Nam compared this process to switching on lights in a classroom, with the switch being a modulator of protein manifestation, and the actual turning on and off, signifying whether proteins were created. However, cells are much smarter than we think, so instead of a binary state of zero and one that signifies whether proteins were created or not, cells can actually regulate protein in a more precise way as they can have a continuous value between the two numbers. “It is like using a sensor that corrects the light’s brightness according to how bright it is outside, instead of simply turning the classroom light on and off or maintaining a degree of brightness,” said Nam. “In order to do this, genes go through the steps of DNA to messenger RNA to protein.” According to internal and external conditions of cells, the degree of protein manifestation is regulated by “transcriptional regulation,” a transferring process that creates RNA from DNA, and “post-transcriptional or translational regulation,” which regulates the process of creating protein from RNA. Nam said his research started during a lunch with Professor Hwang Jung-wook (Department of Genetics), who was at the time conducting a research on RNA quality control. The two talked about gene manifestation regulation research and questioned why UPF1 dependent decay appeared in messenger RNAs. Nam and Hwang soon created a theory and joined hands to test their theory using various data open to the public for around one year. Most of Nam’s research relied on data-driven science, which uses statistical and computational verification using dozens of terabytes of data. Programs, algorithms and pipelines (a set of data processing elements connected in series) were created to analyze and interpret the data. Then, various experiments and samples were used to develop his research. A total of some four years and six months had passed until Nam published his research. Nam (left on front row) poses with students from the Department of Life Science lab. "Data biology’s biggest attraction is its systematic approach to research," said Nam. With the newly discovered gene control regulation principle, Nam believes that it could be used to diagnose and treat various diseases, and can also be used to develop treatment platforms.

[Academics][Excellent R&D] Giving Voice to Those With Developmental Disabilities

Many societies seek to create equal standing for all social groups, which also advances human societies toward democratic order. An important factor in societal evolution is hearing what people have to say, but there are those who are shunned to the outskirts of discussion as their voice is ignored or is transferred to their guardians, who are trusted to speak for those who have difficulties speaking or expressing their mind through gestures. Professor Je Cheol-ung (School of Law) has been fighting for people with developmental disabilities, which includes dementia, mental diseases and disorders, to make society listen to their voices instead of suppressing them in the name of protection. Professor Je Cheol-ung (School of Law) seeks to improve the rights of people with developmental disabilities. “There are those who cannot speak well, but one can see dislike in their expression, which is an expression of refusal,” said Je. “In this way, even if one cannot express themselves through words, they show their intentions in different ways like emotion and feelings. We need to consider whether we are offering a correct service.” Korea has around 400,000 patients with developmental disabilities living in nursing facilities and mental hospitals, which isolates them from society. The lack of caregivers in Korea makes conditions in these facilities unfavorable as one caregiver would have to take care of an average of eight patients. They would often be neglected or even be tied up, literally, and laws do not do much to protect their rights. Elderly struggling from dementia are often swindled into handing over their money or investing in bad businesses. Je’s research on “The Integration of Persons with Impairments for Decision Making Ability into the Communities” has been conducted since 2012, which is funded by the Ministry of Health and Welfare. Je said that the problem behind Korea’s policies for people with developmental disabilities is the low budget, and the public benefits offered are typical and not customized towards individual needs. Je’s team seeks to revise laws so that they can function better to protect the rights of the people with developmental disabilities. The first step in Je’s research is creating a theory on possible revisions. Then, Je’s team visits facilities to interview patients and those involved with their wellbeing and finds out if the theory can actually be implemented. One revision that Je said was a significant result of his research is revisions to the Civil Proceedings Act that allows for people with developmental disabilities to participate in lawsuits instead of being pushed to the sidelines. Je said there are many cases where people with developmental disabilities are excluded from lawsuits that they are involved in, instead replacing them with their legal guardians, or included them in the case without any actual participation. Je led a briefing session on supported decision-making for elderly. (Photo courtesy of Je) What keeps people with developmental disabilities from other social groups is the fact that they are not part of the groups that seek to protect their rights, said Je. These groups are instead led by their legal guardians or lawyers. In order to make their voices heard, Je said that people with developmental disabilities whose conditions are less severe need to take a leading position in these groups and speak for those who are more restricted in expressing themselves. Je believes in de-institutionalization, taking people with developmental disabilities out of facilities and restoring them back in society. Je seeks to move this societal paradigm of substituted decision-making to supported decision-making, which will focus on the autonomous decision by patients instead of relying on the supporting roles of legal guardians. Je (fourth from right) and his team attended a debate on implementing a public trust for people with developmental disabilities. (Photo courtesy of Je) “The definition of a good world is a place where the weak can live comfortably,” said Je. “True democracy is practiced only when the weak speak their minds, and society listens in return.” Jung Myung-suk kenj3636@hanyang.ac.kr Photos by Kim Ju-eun

[Academics][Researcher of the Month] Goal to Create a Safe Driving Environment

In an age where humans can rely on machines for assistance in everyday life, an infinite amount of data is interpreted by machines according to our needs. The wonders of technological advancement are developed in light of the Fourth Industrial Revolution. In the automobile industry, automation has allowed sensors and algorithms to alert and maneuver vehicles under human supervision. Yet, accidents happen, even with the most cutting-edge technology. Professor Park June-young (Department of Transportation and Logistics Engineering, ERICA Campus) emphasizes the issue of safety in his research on enhancing in-vehicle driving assistance information under a connected vehicle environment. Professor Park June-young (Department of Transportation and Logistics Engineering, ERICA Campus) participated in simulation tests himself. According to Park, there are various factors that can lead to driving assistance malfunctions. Sensors can be blocked by physical objects, such as heavy rain, dust, insects, and glare from sun rays reflecting off white vehicles, which could become anomalies for vehicle cameras. Although automobile manufacturers research thoroughly to create driving assisting technology, it is impossible to factor all scenarios, added Park. A solution to this problem is Cooperative-Intelligent Transport Systems (C-ITS), which is a system of information sharing between V to I (vehicle to infrastructure) and V to V (vehicle to vehicle). In-vehicle head-up display (HUD) design scenario samples (Photo courtesy of Park) “Vehicles must be informed of adjacent infrastructures and should share information between V to V, vehicle to vehicle,” said Park. “Only by constantly sharing information about the number of nearby vehicles and their movements, thus acquiring their driving patterns as data, can technology assist in driving, even if the driver cannot see in front of them or their sensors are down.” Park’s research did not only focus on the driving technology of the future, but also on the driving environment of today. His objective was to develop the driving technology of vehicles, but in a safe way. He calls his vision of autonomous driving "autonomous safety-driving." Risk scenario-based HUDs that Park and his team have designed in their research are illustrated above. Depending on risk factors, HUDs display different information in various designs and colors, which were selected most optimally by test subjects. (Photo courtesy of Park) Park was part of a four-man team for a period of around three years, most of which was conducted at the University of Central Florida. Park's research focused on creating a stable environment for driving in dangerous situations, especially during fog, which is a big problem in Florida. Heavy rain and fog in the region make it difficult to see even a few meters ahead. In order to create a solution to this problem, Park oversaw the data acquisition of various driver assistance technologies of automobile companies as well as acquiring subjects to participate in test-driving scenarios. With the data acquired, Park and his fellow researchers developed a head-up display (HUD) based on emotional dimensions and design category factors by factoring in safety factors and user preference. HUDs are any transparent display that presents data without requiring users to look away from their usual viewpoints, which in the case of vehicles is usually displayed on the front window. In 2017, the Korean government announced its goal of achieving partial autonomous driving (with manual overdrive during emergency situations) by 2030. Although Park believes this goal is achievable, he thinks it is impossible without an environment that supports autonomous driving. Park has said that not all cars have autonomy. Regular vehicles and vehicles with assistive driving capacities will have to share roads; thus, in order to coexist in such a shared traffic environment, it is necessary to find anomalies within the system “instead of having a false notion that one will control their surroundings by the car sensor’s readings and drive autonomously.” “I wish the idea of traffic safety is widespread among people,” said Park. “The future is important, but since people living in the present are also important, I plan on working hard to make today’s traffic environment safe.” Park (center in the front row) posed with students from the Department of Transportation and Logistics Engineering research lab in Hanyang University’s ERICA Campus.
