[Academics][Excellent R&D] Laying the Stepping Stones for Future Software Technology

From chemistry to physics, scientific fields take great strides every day. This is even more the case for computer science, with the world having embarked on the 4th industrial revolution - a revolution created through an extensive integration of information technology. Technologies such as artificial intelligence, big data, and the Internet of Things (IoT) have already been brought to reality to a certain extent. In light of these advances, the improvements in software technology by Professor Won You-jip (Department of Computer Science and Engineering) have received grand recognitions for tearing down the barriers to continuous development. The interview with Won You-jip (Department of Computer Science and Engineering) was held in his office on July 4th, 2018. A rough explanation of Won's research would be as follows: if we modify a standard computer, expanding its memory capacity by 100 times, and increasing the number of Central Processing Units (CPU) to 100, the seemingly improved computer would not be 100 times faster than before. In fact, it would be even slower than the standard version. The essential problem lies in the software; the algorithm for the new computer would have to be redesigned to manage the expanded resources in the most efficient manner. “It would be like driving a supercar on an unpaved road,” explained Won, providing a metaphor to emphasize the pointlessness of developing hardware without the sufficient software to manage it. However, the reality is that the speed of software development has remained rather stagnant compared to the restless development of hardware technology. On this point, Won’s research has received a passionate welcome by the international community for paving new roads for the future of software technology. Althernative designs for CPU management and Input/Output management as proposed by Won's research (Photo courtesy of Won Youjip) In a nutshell, Won provided key technologies for operating systems to support scalability, that is, the ability to add more CPUs, and for them to quickly make full use of the software. To elaborate, he categorized the roles of operating systems into CPU management, huge memory management, and file input/output management, and developed essential technologies for each domain after an analysis of the latest trends and prospective future of their hardware. Won essentially solidified the possibility of scalability, maximized the used of large-scale memory space, and improved the I/O management to prevent operation delays. Won’s research was greatly facilitated with the help of the Electronics and Telecommunications Research Institute (ETRI), who granted access to their super computer for research and experiments. With their assistance and his dedication, Won has been recognized as the forerunner in his field, having won two Best Paper Awards from conferences held by USENIX, also known as The Advanced Computing Systems Association. Won was awarded two among the three Best Paper Awards ever given to recipients in Korea. No other countries in Asia have ever won the award. USENIX conferences are the most respected and historical in the field, with the programming language JAVA having been introduced in one of their past conferences. Won considered being awardedthe award for best paper at USENIX to be an extreme honor. Once Won introduces the final version of his work, it is expected to allow software to be designed for manycore (computers with many cores) hardware to be built in 50 to 60 years-time. It will support super computers, allowing AI calculations and machine deep learning. Furthermore, it will be applied to servers to maximize the use of their resources, contributing significantly to their efficiency. Won’s findings not only enable future technology, but make it economic and efficient. Won is also a dedicated instructor. When asked of his greatest aspiration, Won answered that his wish is for his students to become the best developers of Silicon Valley. He interacts with his students on a frequent basis, well above the domains of lab work. A piece of advice that he had for his students was to become the best. “Rise above your failures, keep your head up, and become the best in your field,” commented Won. He believes that regardless of the skill or profession, if there is something you want to do, you should "Start digging and get to the bottom of it.” Lee Chang-hyun pizz1125@hanyang.ac.kr Photos by Kang Cho-hyun

[Performance]Hanyang University Hospital Receives Top Ranking

The Health Insurance Review and Assessment Service evaluates every hospital in Korea and rates them into six tiers, with the last one being "unscorable." Hanyang University Hospital has been rated in the top tier in four major cancer departments for three years in a row. As there are many good hospitals in Seoul, a hospital has to have almost perfect scores in every aspect in order to rank in the top tier. News H visited the director of Hanyang University Hospital, Lee Kwang-hyun to find out their secret. Lee Kwang- hyun , the hospital director, stressed that his efforts to overcome the difficult times were not futile. “There is really no secret to the gradings,” muttered Lee. He mentioned that every member of the hospital including professors', doctors', nurses', pharmacists', and interns' striving to provide better medical service to the patients made it come true. Lee especially credited the professors from each cancer department. The Health Insurance Review and Assessment service’s grading is the result of 2016’s performance. Documents and information were collected last year from September to December, assessed earlier this year, and announced this June. "Safely trustable hospital" (Is this the accepted translation of the motto? It doesn't sound very natural. If it can be changed, I would recommend, "Safe and trustworthy hospital." Hanyang University Hospital's motto. Surprisingly enough, our university hospital had a tough time just a few years ago. Rumors spread that we might have to close due to the worsening management situation. Lee mentioned that there were two things that brought about the betterment of such a dire situation. First was the cooperation between the labor and the management. “Communication is the key. Without it, suspicion and misunderstandings pile up and can cause disasters,” said Lee. Although it is very difficult for two groups with conflicting interests to work harmoniously with each other, through their efforts to be transparent for the workers and members of the hospital, the labor force and the management came to understand each other and worked towards the growth of the hospital. The second aspect was for the hospital to “really work as a hospital” through a “sensible system." Lee acknowledged that in the past, there were some systemic failures where the hospital was not serving the patients but rather focusing on its own interests. For example, the reception desk used to close at 7 p.m. sharp even if there were some patients still in the doctors' office. After the acknowledgment of this shortcoming in service, the hospital tried to amend the system to work for the patients and to provide as high a quality of service as possible. Thanks to the efforts of every member from every corner of the hospital, our university hospital was able to receive not only receive a top-tier rating in the four major cancer departments, but we also scored high on other indexes such as for treating rheumatism, caring for patients who have had a stroke, the use of antibiotics for infants, and more. Lee was confident that the hospital will be ranked in the top tier again next year as well. He commented that the motto of Hanyang University Hospital is to become “safely trustworthy hospital," smiling. Kim So-yun dash070@hanyang.ac.kr Photos by Kang Cho-hyun

[General]A Fair Competition For Overall Advancement

Starting from 2012, Hanyang University has been running an assessment program which evaluates the 58 departments of the Seoul campus and the 38 departments of the ERICA campus. This year the department of tourism managed to rank first out of the 58 departments of Seoul campus, after placing second for the past two years. The assessment program evaluates the departments based on 22 different criteria, which include educational, research, international, and financial indicators. According to Kim Youn-san, chief of the Hanyang Planning and Evaluation team, in order to receive a high rating in the evaluation program, it is crucial to show high performance in all the indicator fields rather than to show exceptional strength in one field. This enables the departments to give a balanced focus upon the various standards stated in the school’s assessment program. In addition, in order to maintain a fair evaluation process, direct comparison between departments is avoided upon necessary criteria. "As for the criteria where information can be assessed, such as employment rates and dropout levels, rather than comparing two different departments directly, each department is compared with the same department within a rival school. For example, the department of Mechanical Engineering is compared with another school’s corresponding department, rather than having a direct comparison with the department of Chemistry,” explained Kim during the interview. This is due to the effort of using a standardized indicator towards the different departments which have various characteristics that should be taken into consideration. Kim Yeon-san, the chief of the Planning and Evaluation Team, maintained that the HYU assessment program does not simply set competition between departments, but is a program that contributes to the overall growth of Hanyang University itself. The department of tourism showed overall high achievement this year according to the evaluation standards. Professor Kim Nam-jo (Department of Tourism) explained how tourism's becoming a more practical subject contributed to the department’s high ranking on this year’s evaluation. He pointed out the high number of internship programs provided, which goes alongside with the high employment rates of the department's graduates. He also maintained the power of the tourism professors' research. “The professors of tourism have managed to achieve a harmonious balance between themselves, which allows them to focus upon their well-divided roles of research,” explained Kim. Professor Kim Nam-jo (Department of Toursim) also shed light upon how the field of toursim can be converged with other various fields, as a reason that the department has ranked high in the evaluation program. As for the high ranking departments within the assessment program, incentives are provided. Such incentives can be used by the departments for the purposes of offering scholarships to students, holding academic conferences, and improving educational facilities. Being the top-ranked department for this year’s assessment program, the department of tourism is expected to receive their rewards, which will further contribute to its future performance.

[General]Goodbye HYU

With June coming to an end, 33 faculty members of Hanyang University (HYU) said their last goodbyes after years of pouring passion and care into the school of over 22,000 students. On June 19th at the Hanyang Institute of Technology (HIT) building, 21 professors from both HYU Seoul and ERICA campuses attended their last official school ceremony. It started off with the dean's last remarks, wishing them the best of luck in the next chapter of their lives. Professors Yoo Eun-kwang (Department of Nursing), Kim Young-what (School of Law), Cho Se-hwan (Department of Urban Planning and Engineering), Kang Yong-soo (Department of Energy Engineering), Choi Dong-hoon (Department of Engineering), Yi Seung-jong (Department of Engineering), Sunwoo Myung-ho (Department of Automotive Engineering), Seo Jeong-gook (College of Medicine), Kim Kyo-sang (College of Medicine), Yoo Hee-jun (College of Medicine), Um Ki-bang (College of Medicine), Lee Yong-sung (College of Medicine), Pih Jong-ho (Department of German Language & Literature), Kim Wan-se (Department of Mathematics), Lee Young-pak (Department of Physics), Lee Tae-sik (Department of Civil & Environmental Engineering), Kim Young-chul (Department of Japanese Language & Culture, ERICA), Lee Hee-su (Department of Cultural Anthropology, ERICA), Kim Myoung-soo (Department of Information Sociology, ERICA), Nam Sang-nam (College of Sports and Arts, ERICA) and Professor Kim Ki-chul (Department of Chinese Studies, ERICA) were present at the ceremony. Retirement ceremony for professors in the HIT building on June 19th 2018 (Photo courtesy of Media Strategy Center) For school staff members, the retirement ceremony was held on June 28th at the new administration building. The 12 staff members also included those from both the Seoul and ERICA campuses, who worked at departments including general affairs management and the administration office. The dean of HYU also joined the two ceremonies to deliver his gratitude. Kook Bang-hyun has worked at the Seoul campus administration office for over 31 years. Having started in 1986, HYU has been a huge part of his life. “I have so many memories on this campus. Ever since I started working here, I’ve worked at a variety of departments and participated in numerous school projects. I've had amazing colleagues and amazing professors to work with. I also know that my successors are so talented that I have no doubt that they will now lead this beloved school to develop.” Lee (left) and Kook (right) leave their last comments after the staff retirement ceremony at the new administration building on June 28th 2018 Lee Jong-tae has worked at the general affairs office at the ERICA campus for 25 years. “I started working in 1993. I actually started at the Seoul campus, but worked longer at ERICA. Luckily, I was able to take part when both campuses were in the process of major changes. Throughout the years they have both changed drastically and I believe more changes for the better are to come. I’m retiring now, but I can see myself visiting the two campuses quite often in the future. Also, I’m not sad to leave, but rather quite excited to see how much it will have changed the next time I come back.” Park Joo-hyun julia1114@hanyang.ac.kr Photos by Lee Jin-myung

[Academics][Researcher of the Month] Finding a Cure Through Direct Intranasal Delivery

Flaviviruses like the West Nile virus (WNV), Japanese encephalitis (JEV), and Zika are neurotropic, causing neurological complications or death to those with low immune systems. There is now a cure in development called the siRNA approach which has demonstrated promising results in treating viral infections in animal models. However, several complications exist when it comes to treating humans. Lee Sang-kyung (Department of Bioengineering), along with his fellow researchers, has come up with a solution in his paper "Small Interfering RNA-Mediated Control of Virus Replication in the CNS is Therapeutic and Enables Natural Immunity to West Nile Virus." Lee Sang-kyung (Department of Bioengineering) explains the direct intranasal delivery process on June 22nd. The small interfering RNA (siRNA) is a therapeutic strategy targeting illnesses such as cancer, inflammation, and genetic disorders. This strategy was proven to be successful in treating various viral infections including encephalitis-induced morbidity and mortality, in animal subjects. However, there have been several complications regarding its application to human brains. One of the challenges was due to human anatomy being quite different from that of animal test subjects like mice. After the long research process, it was clear that direct delivery of siRNA to the brain was the best method of treatment. However, not only was finding the right treatment of viral encephalitis (inflammation of the brain) challenging, but the direct delivery of siRNA effectively across the blood-brain barrier (BBB) was a huge block as well. The blood-brain barrier is a filtering mechanism of the capillaries that carries blood to the brain and spinal cord tissue, blocking the passage of certain substances. This basically means that intruding substances are blocked so nothing goes in, and nothing goes out. This makes it harder for the research to continue. The intranasal delivery device that allows mice to be seated in a natural "Mecca" position. (Photo courtesy of Lee) To overcome this problem, Lee and his fellow researchers came up with the intranasal delivery method that allows a substance's direct delivery to the brain while circumventing the challenges associated with the blood-brain barrier. This method was based on the unique connection in human anatomy between the brain and the outer world through the olfactory nerve. Lee was able to invent an intranasal delivery device for WNV-infected mice at late stages of the neuroinvasive disease in hopes of demonstrating that the treatment would bring results in recovery. The mice seated on the platform were naturally placed into the "Mecca" position, which is the best angle for proper direct drug delivery. The siRNA delivered through this route revealed a remarkable therapeutic effect in reducing brain viral load, neuropathology, and mortality even when the treatment was initiated at late stages of WNV infection. Furthermore, the treatment allowed the natural protective immune responses to be triggered outside of the brain that would result in prevention after recovery. This discovery will allow active studies to be conducted in brain research and therapy in the future. Lee explaining the difference in human and animal nasal cavities in his lab, June 22nd. However, there are still more challenges to overcome. Animal subjects used in the experiments such as mice, have the anatomical difference of having a nasal cavity that is six times larger than that of a human being's. This means that the amount of the substance that can be absorbed through a human nasal epithelium (a type of animal tissue) is reduced. The "Mecca" position is a crucial discovery in the steps to overcoming such challenge, but further research is needed. Lee hopes that through the use of the intranasal drug delivery device, they will be able to discover the optimized method of delivery which will be suitable to human anatomy, thus preventing thousands from suffering and death. Lee's research and discovery can be read in detail in the Cell Host & Microbe scientific journal as well as on Signet Biotech's website (signetbiotech.com).

[Academics][Excellent R&D] Organic-Inorganic Hybrid Multi Layers

Barrier films that have the ability to block moisture and aerial gas have long been a concern of the packaging industry, especially in the display business. The penetration of such substances leads to a degradation of display materials to protect, which is the main reason why barrier films are utilized. Song Tae-seob (Department of Energy Engineering) has provided a solution to this troublesome dilemma, by proposing the use of using organic-inorganic hybrid multi layers. The use of inorganic materials when making a barrier film is highly effective in blocking the penetration of other substances, but the heat treatment and the use of the equipment comes with a high price tag. On the other hand, organic materials have an easier production process, yet are relatively more vulnerable to penetration by moisture and air. Thus, Song has converged these two materials, which would result in a barrier film higher in both ability and cost efficiency. Song Tae-seob (Department of Energy Engineering) explained how converging organic and inorganic materials can result in the production of a barrier with higher abilities and improved cost efficiency. According to Song, there have been techniques to combine the two materials, but they have not yet been applied to the production of barrier films. Thus, the remaining task for Song was to focus upon making a convergence of the two materials and managing to evenly spread and disperse the inorganic material within the organic solution. "Inorganic materials have a tendency to crumple down within an organic solution. Therefore, finding a way to alleviate this mass and allow them to spread evenly within the solution is a key factor to our research," explained Song. Being a professor in the Department of Energy Engineering and primarily studying batteries, Song has had hardships in this relatively unfamiliar field of research. As it is applying an already existing technique, Song and his laboratory members have focused on developing their technologies while avoiding existing patents. Having the need to develop a product from a new perspective with a novel concept, while diverting from current technologies, Song had another barrier to overcome. However, once such hardships are overcome and the current research is fully conducted, the outcomes will be significant. By localizing the novel barrier film technique, the domestic industry will prosper economically. “The domestic display business will benefit from being supplied with products that are more efficient in both cost and capacity. Furthermore, the barriers can also be extended to various businesses such as solar cells, which have also been troubled with moisture and air penetration," commented Song. Song and his students showing their strong will to develop an organic-inorganic hybrid material barrier.

[General]Paiknam to be the Best of University Libraries

Paiknam Library, commonly known as the central library, won the Chairman of the National Assembly Award on May 24th. The prize was awarded by the Korean Association for Research Information (KARI). This meaningful milestone is the biggest award given by KARI, and Paiknam Library is the only university library to have received the prize this year. Our beloved library is 70 years old as of 2018, and the Chairman of the National Assembly Award is not the only award Paiknam has received. It also received the Korean Library Association Award this February. News H interviewed the Dean and the Associate Dean of the library to find out more about these events. From the left, Hong Yong-pyo (Associate Dean) and Eom Ik-sang (Dean of the University Library) are enthusiastically explaining the history and the future of Paiknam Library on June 8th. According to the Associate Dean, the university library was able to win the award from KARI thanks to the usage of the National Assembly library’s electronic resources by Hanyang members. In fact, Paiknam Library is one of the top five libraries in the nation to possess the most books. However, the percentage of books on loan is not as high. “We looked into the issue and discovered that Hanyang members actively download and borrow online resources,” mentioned the Dean. Paiknam Library is also sharing our resources with the National Assembly Library, too. Looking back on the 70 years of the Paiknam Library, there have been a lot of changes going on the past couple of years. The library was remodeled so that more students can enjoy the place more comfortably, and exciting programs such as debate competitions and coffee sessions on how to write good articles were created. Eom smiled and said, “I want the library to be a place students all love, like a second home.” He plans to nurture the place so that students can not only study in the library but also exchange ideas, be entertained, and even take a nap. Hong also mentioned that "The library is heart of the university," and that he will do his best to keep it up. Fifth from the left, Chung Sye-kyun (former Chairman of the National Assembly) is standing next to Hong at the May 24th KARI assembly. The Paiknam Library was awarded the prize on the same day.
