Application Of Burnishing Process Expected To Frictional Heat To Non-Oriented Electromagnetic Steel Sheet, Yuji Kobayashi, Masato Okada

15th International Conference on Shot Peening

Burnishing is a technology used to improve the surface roughness of metals. On the other hand, it is expected that the metal structure near the surface will change due to strong distortion.

The magnetic properties of electromagnetic steel sheets depend on large crystal grains and fine crystals near the surface[1]. In particular, thinner fine crystal grain layers on the surface are expected to reduce iron loss. In this study, the power generation characteristics of Burnished electromagnetic steel sheets were evaluated.

Electromotive force waveform was evaluated by rotating the laminated electromagnetic steel sheets and using a spindle motor. The electromotive force …

Hands-On Stem In Ghana: Inspiration For Culturally Relevant Pedagogy Globally, Alhassan Issifu, Mawuena A. Hanson, Heather R. Beem

Journal of Pre-College Engineering Education Research (J-PEER)

Many educators are increasingly seeking culturally relevant pedagogies they can employ to effectively engage their students. In Ghana a substantive set of hands-on STEM content has been created, incorporating locally available materials and cultural approaches while maintaining alignment to the national curricula. Against a backdrop of almost no public primary or junior high schools in the country containing any lab equipment, this approach leverages and celebrates the abundance of what is available within the locality. This challenges narratives of what is considered “good” and recenters power back with those in the classroom. Three sample activities and three firsthand stories are …

The Potential Benefits Of Co-Design In Dog-Assisted Treatment Programs For Veterans Seeking Mental Health Care, Parvin (Pary) Bahmanyari, Pauleen Bennett, Tiffani Howell

People and Animals: The International Journal of Research and Practice

Veterans are more likely than the general population to experience a range of mental health problems. While many veteran mental health support programs are available, veterans may struggle to access and engage with these services for various reasons (e.g., a stigmatized perception of mental health disorders, mistrust). Animal-assisted services have become more popular in civilian and military health care settings where traditional therapies (e.g., cognitive behavioral therapy) may not always be effective. Assistance dogs, for example, which live with veterans to provide disability support, have been successfully employed for veteran mental health. Unfortunately, a subgroup of veterans may miss out …

Behavioral Bias And Manager Success In Major League Baseball, Daniel Pastor, Jason R. Reed, Arjun Sondhi

Department of Agricultural Economics Faculty Publications

Using results from 26 Major League Baseball seasons, we investigate the connection between behavior bias, managerial success, and tenure. We ask whether managers that have overachieved, relative to prior seasons, have a greater chance of remaining in that role, and if so, what was the subsequent effect on team performance. Our results indicate that MLB owners and team general managers are susceptible to behavioral biases. Team managers that overachieve in a season, relative to recent, historical team performance, endure longer tenures with their team, however, overachieving managers have statistically similar career win percentages to managers who underachieved. This result suggests …

Korea’S Unification: Unifying Visionary Leadership, Paul Hong

KAUPA Letters

This third essay highlights the critical role of unifying visionary leadership in advancing Korea’s unification—a goal that cannot be achieved through policy frameworks or economic integration alone.

Korea At The Crossroads: Steering Between Two Paths In The New Global Trade Order, Paul Hong

KAUPA Letters

Korea stands at a pivotal crossroads in global trade, caught between the twin forces of rising protectionism and the emergence of a multipolar economic order. Once a major beneficiary of U.S.-led free trade, its export-driven growth thrived under predictable rules and open markets. That stability is now eroding as the United States shifts toward protectionism—driven by mounting debt, persistent trade deficits, and the burdens of overextended global commitments—through tariffs, reshoring incentives, and strategic restrictions on key sectors like steel, semiconductors, and electric vehicles. These measures have disrupted Korea’s supply chains, complicated market access, and heightened uncertainty, even as China’s economic …

Practicing The Art And Craft Of Screenwriting: Analysis And Opportunity From A Faith-Informed Perspective, Kevin R. Crawford

KAUPA Letters

This paper describes the commitments and standards of practice required by those wishing to write from a faith-informed perspective – particularly, a Christian worldview frame. It highlights elements of Minkyu Lee’s award-winning animation Adam and Dog (2011) by way of illustration and argues a new role for faith-informed storytelling that correctly resists the temptation to preach especially in a world where any project deemed to promote an organized religious agenda, however simple or subtle, is apt to be ridiculed, marginalized, and ignored.

A Certainty-Based Approach To Implementing Zero Trust Architecture Using Nist Sp 800-207 And Nist Sp 1800-35, Young B. Choi

KAUPA Letters

This paper proposes a certainty-based methodology for implementing the Zero Trust Architecture (ZTA) as defined in NIST SP 800-207 and NIST SP 1800-35 (NIST, 2020; NIST, 2025). By applying a probabilistic model that quantifies the certainty of security-related facts, the proposed approach enhances decision-making for access control and security policy enforcement. This method utilizes major security databases to assess and compute certainty of facts, thereby improving the resilience, adaptability, and accuracy of Zero Trust systems (Liu, Chandramouli, & Kuhn, 2020).

Contributing Factors To Low Airspeed On Climb-Out As A Precursor To Loss Of Control In Flight, Owen D. Poborsky

Journal of Aviation Technology and Engineering

The nature of aviation is not without inherent risk. Conducting training flight operations increases these inherent risks. Flight data monitoring and voluntary safety action programs seek to reduce risk, as seen in their success at commercial airlines. These successes are slowly permeating into general aviation through programs such as the National General Aviation Flight Information Database (NGAFID). The NGAFID is a program funded by the Federal Aviation Administration that allows general aviation operators to have the ability to collect and share de-identified flight data on an aggregate level to identify trends and increase safety margins during flight operations. This study …

Research Synthesis Of Predicting Part 135 Accident Probability In Aviation: How The Bayesian Brain Ignores Declining Safety Standards, Jonathan R. Clarke

Journal of Aviation Technology and Engineering

Technological innovation has had an enormous effect on safety in aviation. However, in Part 135 operations, where technology is not as ubiquitous, the accident rates have plateaued. Human error is constantly misrepresented as being responsible for 70–80 percent of accidents, when it is clearly only one of several contributing factors. In commercial aviation, all accidents should be considered organizational failures, because by definition all defensive layers have been breached. Organizational failure, as it affects safety, should be identifiable and predictable from organizational behavior. Inevitably, in the aftermath of accidents the warning signs of poor behavior are seemingly obvious, yet there …

Enhanced Global Oil Spill Dataset From 1967 To 2023 Based On Text-Form Incident Information, Yiming Liu, Zhuoli Yin, Hua Cai

The School of Sustainability Engineering and Environmental Engineering (SEE) Faculty Publications

Knowing how much oil was released into the environment in each incident is critical to studying the environmental, ecological, and economic impacts of oil spills. However, the release amounts (RAs) for numerous oil spill incidents remain unavailable in a structured format for large-scale analysis. The most extensive global oil spill database, managed by NOAA’s Office of Response and Restoration, only documents the worst-case scenario estimations in the machine-readable dataset, while more accurate values are embedded within unstructured incident descriptions and subsequent updates. To enhance the dataset with more accurate RAs, we developed a framework to extract the actual RAs from …
