Resilient Performance: How One Hospital Dealt with a Mass Burn Casualty Event

 Seminar by Dr. Sheuwen Chuang

 CEO at Health Policy and Care Research Center

Associate Professor at School of Health Care Administration, Taipei Medical University

 Wednesday, September 20th, 2017 from 4:00 – 5:00 pm

Smith Lab 1005, 174 W. 18th Avenue

The Formosa Fun Coast Dust Explosion (FFCDE) occurred around 20:30 on Saturday June 27 2015 at the Formosa Fun Coast Park in New Taipei City. Nearly 300 emergency vehicles were dispatched. Within 6 hours, 499 victims were delivered to 34 hospitals. Victims, average age of 23, wore flammable swimwear resulting in large total body surface area burns (TBSA, average 44 %; 281 people with TBSA > 40%, 41 people > 80%). The talk will focus on how one public hospital responded to the surge in patients from the FFCDE disaster.

This study applies resilience engineering concepts and cognitive systems engineering techniques for data analysis. Under overwhelming demand and uncertainty for the hospital that does not specialize in emergency burn cases, the study reveals how the hospital demonstrated resilient performance in dealing with difficulties over multiple dimensions, i.e. medical materials, ICU/general ward beds, personnel, and ED space. The talk will cover how clinical staff adapted to handle the patient surge.

 Dr. Sheuwen Chuang is CEO, Health Policy and Care Research Center, and Associate Professor, School of Health Care Administration, Taipei Medical University. She also is part of the international Resilient Health Care Network which had its most recent meeting this summer in Vancouver. Dr. Chuang has been consultant for patient safety management and quality improvement in hospitals for more than 10 years.

She received her PhD in Industrial Engineering and Enterprise Information from Tunghai University, Taiwan. She was a post-doctoral researcher in the School of Medicine & Public Health, University of Newcastle, AU, which was funded by Endeavour Research Fellowship Awards from Australian Education International in 2008-2009.

She has been visiting the ISE department this summer working on applying Resilience Engineering to emergency medicine and other health care issues.


ISE Welcomes Ill Ryu

Size dependent mechanical behaviors in metals: Defects make materials interesting

Seminar by Ill Ryu, Assistant Professor

Mechanical Engineering, University of Texas at Dallas

Thursday, August 31st  from 11:00am – 12:00pm

210E Baker Systems, 1971 Neil Avenue

Nanotechnology attracts much attention due to not only its useful engineering applications, but also their superior material performances. As the dimensions of the devices become smaller and smaller, however, understanding the mechanical properties of materials at sub-micron length scales becomes more challenging. This is driven by the knowledge that many mechanical properties at the sub-micron scale differ from those at the macroscopic scale and, in addition, mechanical deformations are coupled with other concurrent physical phenomena, such as diffusion, chemical reaction, and phase transformation. For the reliable design of MEMS or NEMS devices, nanotechnology has always called for an understanding of the mechanical behaviors of materials at small length scales. In this talk, size dependent plasticity in metallic micropillars will be discussed in terms of dislocation mechanics. Considering dislocation sources from the surface, micropillar plasticity will be analyzed using three dimensional dislocation dynamics model to understand how dislocation behavior relates to mechanical response in metals. In addition, we also have performed dislocation dynamics simulation to investigate the size effect in bi-crystalline FCC micropillars, taking account for the role of the grain boundary as both a source and a sink. Our simulation results show the smaller size effect in bi-crystalline micropillars, showing hardening for larger samples, softening in smaller samples due to the existence of grain boundary.

Ill Ryu is currently an assistant Professor in Mechanical Engineering at University of Texas at Dallas. Ill Ryu received his Ph.D. degree in Materials Science and Engineering with minor in Mechanical Engineering from Stanford University. After completing his Ph.D., Dr. Ryu continued his research as a postdoctoral research fellow and lecturer at Brown University. His research interests include multi-scale computational material science, materials mechanical size effect, mechanics of energy materials, and multi-physical modeling of materials science. Especially, his research focused on fundamental understanding of deformation mechanism, which is necessary to design robust and reliable devices from MEMS/NEMSs (Micro-/Nano-Electromechanical Systems) devices at small length scales to Airplane at large length scales.

Bringing context to the classroom

After hearing engineering education pioneer Richard Felder speak about the importance of bringing context to a problem in engineering classes, Professor Aimee Ulstad had an idea. Why not involve industry partners in her production planning and facility layout course to bring key concepts to life?

Fresh from a 30-year engineering career in industry, the assistant clinical professor of integrated systems engineering (ISE) knew she learned better when concepts were introduced with real-world context and she had a hunch students would too.

“Much of the material covered in this class is used daily in most corporations. Even if they don’t use it exactly like it is taught in the textbook, they use the principles,” she said. “It seemed evident that if students understood the importance and could learn from professionals using these methods, they would understand the concepts better.”

Recruiting interested supply chain professionals wasn’t difficult, Ulstad said. Both Ohio State alumni and other industry partners alike enthusiastically volunteered to share their time and experience with small groups of four students. During spring semester, 16 mentors participated,  representing a diverse range of organizations, Abbott, AGC Automotive, All-Clad, American Woodmark, American Red Cross, Caterpillar, GE Aviation, Greif, Honda of America Mfg., L Brands, PepsiCo/Quaker, Rockwell Automation, TE Connectivity, Ventura Foods, Walmart and Worthington Industries.

Alumnus John Seeley (’05, ISE), a continuous improvement and environmental engineer for AGC Automotive, is one of several mentors who has remained involved since Ulstad first implemented the live case study format four semesters ago.

“My senior year at Ohio State, I was an undergraduate teaching assistant in the First-Year Engineering program under Dr. John Merrill. This is where I began mentoring other students and I really enjoyed it,” Seeley said. “When Aimee asked for volunteers to mentor her students in 2015, I was happy to help out and give back to Ohio State.”

In addition to being impressed with the students’ enthusiasm and excitement, he has even shared some of their questions with company management for further discussion.

“They help generate new ideas,” Seeley explained. “Sometimes the questions that the students ask can be challenging. Those kind of questions can be a benefit to me and provide a different outlook for the company.”

Ranging from recent graduates to high-level executives, each mentor dedicates a few hours over a series of five conference calls to discuss how their company applies key class concepts. Many local mentors also invite students to visit their workplace and attend class at the end of the semester to hear students’ final presentations.

“One of the best parts is really taking our concepts in class and applying it to the real world,” said Alex Vanek, a third-year ISE major. “It really spurs a lot of passion and drive to want to study and truly know this stuff. I even take what I learn in class sometimes and pursue it further. Having that mentor really allows you to go above and beyond.”

Vanek and his peers agree that learning about operations management, inventory management, production planning and scheduling, demand forecasting and other key course concepts is much easier when you understand how they’re applied at familiar companies.

ISE major Melanie Larson’s mentor at TE Connectivity brought the differences in global economies to life through his discussion of vehicle demand. In China, for example, environmentally friendly cars sell quickly thanks to government incentives. In contrast, low gas prices in the United State are contributing to growing sales of trucks and SUVs.

“The difference in demand on a global scale is really interesting to see and I don’t think I would have understood that if I hadn’t worked with a mentor,” Larson said. “I think it’s really beneficial because when you have one company, you can get more in-depth.”

Students write five papers throughout the course, including one that can be on any topic. At the end of the semester, each group gives a 10-minute presentation showcasing how course topics are applied at their mentor’s company. So in the end, students leave the course with 15 real-world examples instead of just one.

Ulstad has noticed great improvement in student learning since incorporating the live case study format.

“Students really love it. They absorb it,” she said. “When the students know the material matters in their potential future career, they are more likely to hone in on it.”

For many mentors, Ulstad’s course is one they wish they could have taken as a student.

“If I’d had this experience as a student it would have been mind-opening,” said Carrie White, business administrative coordinator for Honda Purchasing Operations, Mass Production Packaging at Honda of America Mfg., who has served as both a mentor and presenter in the course. “Some of the stuff I’m talking about you just don’t even experience it until you’re in it. And to hear it from somebody else, twice a month, it’s pretty cool.”

Ulstad’s efforts to improve the course has been noticed by her peers and college leadership. She presented initial research about the effectiveness of the format at the American Society for Engineering Education’s conference and received the 2017 David C. McCarthy Engineering Teaching Award from the College of Engineering.

But her work to create more innovative and effective teaching and learning is perhaps most appreciated by the students who benefit from it.

“She’s not only a great professor, but also a mentor and role model,” said Vanek. “I can see how much she really cares about students, and wants to make our experience the best possible and prepare us for the real world.”

This seminar presents a cyber-based design and additive manufacturing (AM) for custom orthoses. Orthoses, also known as braces, are assistive devices for structural support of the neuromuscular and musculoskeletal systems to help people with impairments to regain their mobility and independent living.  Custom orthoses have personalized fit, better comfort, and superior efficacy in treatment than pre-fabricated ones for users.  A cyber-physical service system (CPSS) has been developed for the University of Michigan Orthotic and Prosthetic Center (UMOPC).  CPSS has the digital scanning, cyber-design center, and fused deposition modeling (FDM) for AM that aim to improve the quality of patient care and service of custom orthoses.  This CPSS will be implemented at UMOPC for custom ankle-foot orthosis (AFO).  The fabrication time and material cost for 3D-printing are critical to provide advantages over the conventional plaster molding for fabrication.  This system targets to achieve the one-day visit for patients who need AFO.  Key elements of CPSS presented in this talk include the: 1) 3D scanning of the foot and leg, 2) computer aided design for clinicians, 3) cyber- and model-based design, 4) wavy structure tool path planning for AFO, 5) FDM for hard structure and soft silicone for wearable assistive devices, 6) quality control using the nano-CT technology, and 7) inertia measurement unit (IMU) for gait analysis, evaluation, and monitoring of users.  Expansion of CPSS for prosthetic socket, foot orthoses, and other assistive devices are elaborated.

Albert Shih is Professor in Mechanical Engineering, Biomedical Engineering, and Integrative Systems + Design (ISD) at University of Michigan and Assistant Director of Technology, Advanced Manufacturing National Program Office (AMNPO). He was a manufacturing process development engineer from 1991 to 1998 at Cummins.  Dr. Shih’s research area is design and manufacturing. He is a pioneer in biomedical manufacturing, the application of manufacturing technologies to advance the safety, quality, efficiency and speed of healthcare service and biomedical science.  He has 9 US patents, a textbook in Machining and Machine Tools, and authored or co-authored over 180 archival journal papers, 100 conference papers in manufacturing and biomedical sciences.  Dr. Shih is the recipient of many awards including the Fulbright Scholar, ASME Milton Shaw Manufacturing Research Medal, Society of Automotive Engineers Ralph Teetor Educational Award, and Best Paper awards in ASME International Manufacturing Science and Engineering Conference (MSEC), North American Manufacturing Research Conference (NAMRC), International Conference on Frontiers of Design and Manufacturing (ICFDM) and several other manufacturing and healthcare conferences.  Dr. Shih is Fellow of both ASME and SME and associate member of CIRP.  He received his B.S. and M.S. from National Cheng Kung University and Ph.D. from Purdue University.

ISE Professor William Marras Honored as Distinguished Scholar

Recipient of $31 million in research grants, contracts

It’s not surprising that when the recent list of Distinguished Scholar Award winners at The Ohio State University was announced, Williams Marras’ name was on the list.

Marras, who holds the Honda Chair in the Department of Integrated Systems Engineering at Ohio State and serves as the Director of the Spine Research Institute as well as Executive Director for the Institute for Ergonomics, has a list of accomplishments longer than most people’s, well … spine.

Marras said he was surprised when College of Engineering Dean David Williams, Ohio State Vice President for Research Caroline Whitacre and Marras’ colleagues came by to share the news in late February. He was even more taken aback when Dr. Whitacre cited some of his accomplishments, including the $31 million his research has generated in grants and contracts to further the study and improve the well-being of people with back pain. Marras had never tallied it up before. “I thought, ‘Wow! That’s pretty impressive,’” he said.

But Marras is quick to share the credit. In fact, he says, “It’s all about the team,” when asked which of his many achievements makes him the proudest.

“I have a great staff and a great bunch of students,” he says. “I take pride in seeing them evolve and what they are able to do in the lab to break new frontiers of knowledge. That’s what gets me excited.”

Marras, who has been a professor at Ohio State for 35 years, and his team continue to break new ground in spine disorders. “One of our proudest accomplishments is building personalized models of a patient,” he says. By utilizing a patient’s diagnostics, such as MRIs and CT scans, the Spine Research Institute can build a dynamic model of an individual to determine the best approach for treatment.

He points out that the College of Engineering and the University are the reasons that these types of breakthroughs can happen. “The environment here at Ohio State has been tremendous,” Marras says. “Dean Williams has opened up doors and opportunities for us to be successful and thrive.”

He acknowledges his team – Greg Knapik, Jon Dufour, Alex Aurand, Prasath Mageswaran, Sue Ferguson and Gary Allread – as being the “core of helping this come together.”

In their letter to Marras announcing his award, Ohio State President Michael Drake and Dr. Whitacre noted that Marras joins “an elite group of faculty at Ohio State … recognized for their accomplishments in all areas of research and creative endeavor.”

According to Janet Weisenberger, Senior Associate Vice President in the Office of Research, “very few scientists have such a broad and translational impact” as Marras has had. “Dr. Marras’ work is particularly impressive because he has made extraordinary contributions to both the basic science and the applications of biomechanics and spinal injury,” says Weisenberger, who oversees the Distinguished Scholar Award program and serves as chair of the selection committee. “Thus, his work not only gives us a better understanding of basic biomechanics theory and modeling, but also has helped in a practical way to reduce the incidence and severity of workplace injuries.”

Marras was elected a Fellow of the American Association for the Advancement of Science in 2013 based on evaluations by peer scientists, and is a fellow of six other national and international distinguished organizations.

In addition to numerous papers he has written, committees he has served and awards he has won, Marras holds three patents on apparatuses for monitoring the motion components of the spine. He is a much sought-after consultant for corporations such as Ford Motor Company, RCA, Ross Laboratories, Steelcase, Honda of America, The Limited, Target, Sears, Safeway and Costco.

Marras has presented to NATO and the National Academy of Sciences, as well as regional, national and international organizations. His work has appeared in hundreds of publications and he has authored or co-authored eight books on ergonomics and contributed to dozens of others.

He is a member of nearly every professional society in his field, including the International Ergonomics Association, the International Society for the Study of the Lumbar Spine, the New York Academy of Sciences and the National Academy of Engineering, and served as the past president of the Human Factors and Ergonomics Society – the world’s largest organization in this space. Throughout his career, Marras has mentored and advised countless numbers of students and colleagues.

He earned his PhD in Bioengineering and Ergonomics and a master’s in Industrial Engineering from Wayne State University, and a bachelor’s in Systems Engineering – Human Factors Engineering from Wright State University, and holds an honorary doctorate from University of Waterloo. Marras also served in the Ohio Air National Guard where he earned the rank of Sergeant.

Marras and other Distinguished Scholars will be recognized at a May 2 reception at the Wexner Center for the Arts and during a football game in Ohio Stadium this fall.
