Digital Patient Engagement At A Perioperative Surgical Home Implemented Community Hospital, Srinivasan Sridhar, Amy Mount Hunter, Bernadette Mccrory
Patient Experience Journal
Patients in rural areas typically require more perioperative ‘optimization’ for surgery. The rural healthcare systems often overwhelmed with coordinating perioperative services and deliver less than optimal surgical outcomes. This is due to limited supporting microsystems and ability to effectively engage and track patients over the 120-day perioperative period to limit post-surgical complications. The study assessed longitudinal patient engagement within a newly established Perioperative Surgical Home (PSH) at a rural community hospital serving 10+ surrounding counties to identify barriers and best practices for engagement. A digital patient engagement platform was implemented and used to assess longitudinal patient outcomes and engagement from …

Numerical Modeling And Analysis Of Strengthened Steel–Concrete Composite Beams In Sagging And Hogging Moment Regions, Ayman El-Zohairy, Suzan Mustafa, Hesham Shaaban, Hani Salim
Faculty Publications
Strengthening of composite beams is highly needed to upgrade the capacities of existing beams. The strengthening methods can be classified as active or passive techniques. Therefore, the main purpose of this study is to provide detailed FE simulations for strengthened and unstrengthened steel–concrete composite beams at the sagging and hogging moment regions with and without profiled steel sheeting. The developed models were verified against experimental results from the literature. The verified models were used to present comparisons between the effect of using external post-tensioning and CFRP laminates as strengthening techniques. Applying external post-tensioning at the sagging moment regions is more …

The Effect Of Mental Demand On Body Postures, Rodrick Adams, Valentina Niño
Symposium of Student Scholars
How we perceive our work has a profound relationship with how our body reacts to help facilitate the performance of our tasks. This is an observational study of the experiment in which participants performed tasks under four different conditions (baseline, interruptions, time, and alarm) and used NASA-TLX (NASA- Task Load Index) scores to assess their mental workload for each condition across six dimensions: mental demand, physical demand, temporal demand, effort, performance, and frustration level. We juxtaposed their NASA-TLX score with corresponding REBA (Rapid Entire Body Assessment) scores while standing and RULA (Rapid Upper Limb Assessment) scores while sitting to determine …

The purpose of this report is to research and implement new ways to redesign the KSU Johnson Library map and increase the amount of navigation signage. Through time studies and surveys, the team identified resources that take a long time to find. A second round of time studies and surveys was conducted to ensure that the new implementations, signages, and maps are effective. The team also suggests redesigning the floor plans to make them clearer and easier to understand. Team Scrappy concludes that the redesigned map and library signage have significantly improved the ease of navigation within the Johnson Library. …

Reducing Restaurant Inventory Costs Through Sales Forecasting, Tyler Mason, Chris Schoen, Trevor Gilbert, Jonathan Enriquez
Senior Design Project For Engineers
Family Restaurant is a local restaurant in the greater Atlanta area that serves a variety of dishes that include an assortment of 19 different proteins. Currently, Family Restaurant places protein orders based on business intuition, and tends to over-stock and sometimes under-stock. To minimize inventory costs by reducing over-stocking and preventing under-stocking of proteins, we applied Facebook Prophet (FB Prophet), ARIMA, and XG Boost machine learning models to predict protein demand and then fed these results into a Fixed Time Period inventory model to make an overall order suggestion based on the specified time period. We trained our models on …

Senior Design Project For Engineers
Hansen Technologies, based in Commerce GA, is a global leader in the production of industrial refrigeration. One of their most profitable product assembly cells, the Multivalve Platform cell, is not currently producing enough to meet increasing demand. The MVP team focused on analyzing and designing a system using Kaizen to improve the throughput of the MVP cell. After conducting a root cause analysis through Gemba and video analysis, key areas were noted for improvement. Small inconsistencies, such as losing grip on the heavy MVP and searching for materials can take a lot of time away from achieving higher throughput levels. …

Campus Research Month
Cybersecurity is a very important factor that is often overlooked until one becomes a victim of hackers and viruses. One of the main institutions that are caught off guard by cyber issues are high schools. Adventist high schools often fall into this issue as well. It is very dangerous because of the sensitive information handled on school networks as well as the financial loss that cyber security attacks may cause. Moreover, just a few Adventist high schools have IT staff who are qualified to protect the school from cyberattacks or to help with recovery. Therefore, our contribution is to create …

A Comparison Of Nonverbal And Paraverbal Behaviors In Simulated And Virtual Patient Encounters, Sarah Powers, Mark W. Scerbo, Matthew Pacailler, Macy Kisiel, Baillie Hirst, Ginger S. Watson, Lauren Hamel, Fred Kron
Modeling, Simulation and Visualization Student Capstone Conference
The present study assessed whether trainees display similar nonverbal and paraverbal behaviors when interacting with a simulated (SP) and virtual patient (VP). Sixty second slices of time following four interactions were rated for the presence and frequency of three nonverbal and paraverbal behaviors. Results revealed that students exhibited fewer behaviors in the VP interaction, possibly due to differences social inhibition or fidelity between the two formats.

Manufacturing & Industrial Engineering Faculty Publications
Naphtha is an important distillation product of crude oil, and is used as a raw material for first-generation products such as ethylene, propylene, gasoline, xylene (BTX), and others. However, due to the different sources of crude oil, differences in naphtha composition impact the quality of conversion processes. Parameters such as pressure, charge flow, and temperature need to be adjusted for conversion efficiency. This work aims to compare naphtha samples from different origins, through the analysis of distillation curve (ASTM D86), density (ASTM D4052), total sulfur (ASTM D4294), and n-paraffins, iso-paraffins, olefins, naphthene, and aromatics (PIONA, ASTM D5134). Among these parameters …

Effective Use Methods For Continuous Sensor Data Streams In Manufacturing Quality Control, William Hitchcock
Senior Honors Theses
This work outlines an approach for managing sensor data streams of continuous numerical data in product manufacturing settings, emphasizing statistical process control, low computational and memory overhead, and saving information necessary to reduce the impact of nonconformance to quality specifications. While there is extensive literature, knowledge, and documentation about standard data sources and databases, the high volume and velocity of sensor data streams often makes traditional analysis unfeasible. To that end, an overview of data stream fundamentals is essential. An analysis of commonly used stream preprocessing and load shedding methods follows, succeeded by a discussion of aggregation procedures. Stream storage …

Abstract: Virtual power plant technology provides an effective means to aggregate distributed power and user side resources to participate in power scheduling. Most of the existing research focus on the scheduling optimization of distributed energy instead of the demand response of user side. The user side resources are divided into contracted reliable response load and non-contracted random response load, and the load response is regulated through price adjustment mechanism to adapt to the change of distributed. A virtual power plant optimal scheduling model with dual demands response is constructed, in which the maximizing overall profit of the power grid is …
