Introduction
Changwon will be joining Texas Tech University as an assistant professor. Changwon's research interests include cognitive systems engineering and human factors in complex socio-technical systems such as disaster management, oil and gas, and healthcare industries. Changwon received his master's in Safety Engineering from Mary Kay O'Connor Process Safety Center after spending 7 years in the shipbuilding and offshore company as a project HSE manager.

BACKGROUND Mental health is an increasing concern among vulnerable populations, including college students and veterans. OBJECTIVE The purpose of this study was to determine if mobile Health (mHealth) technology combined with health coaching can better enable user to self-manage their mental health. METHODS This study evaluated a mobile Biofeedba...
Article
This study proposes a novel coding framework to quantify and categorize the differences between Work-As-Imagined (WAI) and Work-As-Done (WAD) based on the Safety-II perspective. While the Safety-I approach focuses on controlling deviations from Standard Operating Procedures (SOPs) as the solution to prevent incidents, this framework aims to describ...
Article
Investigating real-life disasters and crises has been challenging due to accompanying difficulties and risks posed by these complex phenomena. Previous research in the emergency management domain has largely relied on qualitative approaches to describe the event after it occurred. To facilitate investigations for more generalizable findings, this p...
Article
This paper proposes a novel framework to evaluate procedural task performance from a Safety-II perspective. While deviations from procedural steps have been a major focus of Safety-I approach, the novel framework aims to capture human operators’ adaptive behaviors and efforts in accomplishing higher-level goals. By adopting abstraction hierarchy, f...
Article
The differences between ‘work as imagined’ (WAI) and ‘work as done’ (WAD) reflect theoretically pervasive and well-known barriers to the examination of human performance at work. Due to the dynamic and situational nature of work, the idealized performance reflected in procedures is not always done as prescribed. The identification and examination o...

Background: Evidence suggests that the COVID-19 pandemic has generally increased levels of stress and depression among the public. However, the impact on college students in the United States has not been well-documented. Objective: This paper surveys the mental health status and severity of depression and anxiety of college students in a large un...
Article
There is a growing need for resilience in dealing with unexpected events during disasters. The purpose of this review was to summarize and synthesize the literature that examined resilience in the context of emergency management (EM). Four groups of findings were synthesized: definitions, key dimensions, technical tools, and research settings emplo...

BACKGROUND Evidence suggest that COVID-19 pandemic has caused increased levels of stress and depression among the public. However, the impact on college students in United States has not been documented. OBJECTIVE This article reports findings of an online survey regarding mental health conditions of college students in a large university in the U...
Article
In large-scale extreme events, multidisciplinary crisis management teams (CMTs) are required to function together cognitively. Despite theoretical maturity in team cognition and recurrent emphasis on cognition in the crisis management practices, no synthesis of theoretical and practical discourses is currently available, limiting empirical investig...

Communities face unforeseen threats from natural and human made disasters. As disasters grow more intense and critical infrastructure increases in complexity, resilience has emerged as an essential attribute of incident management systems. Despite concerted efforts to examine government organizations and their associated policies, understanding res...
Article
Modern communities face escalating threats from natural disasters. Thus, resilience of incident management teams (IMTs) during adverse events becomes crucial to protect lives and physical systems. However, prior studies have only partially highlighted factors related to IMT resilience. To provide a holistic understanding of resilience of the IMTs,...
Article
Multidisciplinary incident management teams (IMTs) are required to operate in resilient ways as emergency situations unfold unexpectedly. Although resilience in emergency management has been widely studied in many emergency contexts, the development of a new method to investigate actual resilient performance of the IMTs under realistic settings has...
Conference Paper
Standard operating procedures (SOPs) are an integral part of everyday operations in oil & gas and petrochemical industries. Also, a majority of incidents in these processing operations are ascribed to issues associated with SOPs. Although there have been continuous efforts to improve quality of SOPs and ensure accurate perception of information in...
Conference Paper
While resilience in emergency management has been studied at the macro- (government) and micro-levels (individual field responder), little is known for resilience of incident management teams (IMTs). To investigate challenges and resilience factors of IMTs, this paper documents thematic analysis of 10 interviews with emergency personnel who respond...
Article
Emergency Departments (EDs) in the U.S. have long experienced difficulties in meeting the often-unexpected healthcare demands resulting in widespread overcrowding. Understanding performance adjustment in such complex systems would inform initiatives to improve ED resilience to expected and unexpected demands. Resilience Engineering (RE) literature...
Conference Paper
Emergency responders work collectively as an ad hoc team to save lives and infrastructures at risk, despite their varying experience, knowledge, cultural backgrounds, and difficult working conditions with high-levels of uncertainty and timepressure. Cognition, in particular, has gained attention as a key construct to consider in collective response...
Conference Paper
Disasters have revealed persistent challenges for incident management systems in preparing for, responding to, and recovering from disruptive events. Such challenges have been reflected in recent catastrophic events such as natural disasters, industrial accidents, and terrorist attacks. To address the challenges, a need for resilience of incident m...

Written procedures are an important artifact in maintaining the safety in high risk industrial operations. Procedures set out the steps required to complete safety and process critical tasks. However, as Sidney Dekkar noted, while procedures spell out how to do the job safely, “following all the procedures can lead to an inability to get the job do...
Conference Paper
Full-text available
In order to cope with increasing complexity of catastrophic disasters, resilience is considered an essential capability of an incident management system (IMS). As resilience is manifested during systems operation, a naturalistic observational study was conducted to understand how resilient performance dynamically takes place in this domain. The stu...

Inherent limitations of controlling risks in complex socio-technical systems were revealed in several major catastrophic disasters such as nuclear meltdown in Fukushima Daiichi nuclear power plant in 2011, well blowout in Deepwater Horizon drilling rig in 2010, and Hurricane Katrina in 2005. While desired risk management leans toward the prevention...

This paper highlights the importance of integration of human factors engineering (HFE) principles throughout phases of system life cycle of offshore energy industries. Human error is found to be the most common cause of offshore incidents according to the analysis of BSEE incident data. While human operators are mostly blamed for making errors and...
