Accuracy of 3D printed Models vs Traditional Stone Models.
-
Abstract/Description
-
3D models are an essential device used in various fields of dentistry. Dental models are used for the fabrication of crowns, dentures, orthodontic treatments, and surgical equipment. Traditionally, 3D models are created from gypsum stone. However, 3D printed resin may provide a higher degree of precision and ease of sharing between professionals. Multiple studies have confirmed the accuracy of the Trios 3Shape 3D scanner, but few studies provide information on the reliability of 3D printers....
Show more3D models are an essential device used in various fields of dentistry. Dental models are used for the fabrication of crowns, dentures, orthodontic treatments, and surgical equipment. Traditionally, 3D models are created from gypsum stone. However, 3D printed resin may provide a higher degree of precision and ease of sharing between professionals. Multiple studies have confirmed the accuracy of the Trios 3Shape 3D scanner, but few studies provide information on the reliability of 3D printers. The purpose of this study is to determine the dimensional accuracy of 3D printed models for future application in dental and orthodontic treatments. Four anonymous participants received an alginate impression and 3D dental scans on the upper and lower dental arches for a resulting sample size of n=4. Prints were made from a Form Labs Form 2 3D printer and an Anycubic Photon 3D printer. These prints, as well as the gypsum model resulting from the alginate impression, were designated specific dental markers in which measurements were taken. Graphs of width and height were constructed after data analysis on Excel. There were no statistically different measurements between models of the same patient. Expected statistical differences were seen between patients, due to being different samples, which helped to validate the width and height measurements as statistically sound. This indicates that the measurements taken from stone models are as accurate as the 3D printed models. 3D printed models would be beneficial for cost reduction for orthodontic treatment and provide immediate surgical guides or dental study models.

Benefits of Open Educational Resources Adoption.
-
Abstract/Description
-
Through a series of workshops and incentives faculty will learn the benefits of adopting open educational resources (OER) in their classroom in place of costly publisher provided textbooks. Participants will commit to adopting OER in their course for at least three semesters. Indian River State College librarians know the value of OER having only taught credit courses using OER materials. Furthermore, librarians specialize in collecting, storing, describing, and evaluating information....
Show moreThrough a series of workshops and incentives faculty will learn the benefits of adopting open educational resources (OER) in their classroom in place of costly publisher provided textbooks. Participants will commit to adopting OER in their course for at least three semesters. Indian River State College librarians know the value of OER having only taught credit courses using OER materials. Furthermore, librarians specialize in collecting, storing, describing, and evaluating information. Knowledge of OER and access to over one million library licensed scholarly materials makes a librarian the best person to implement college-wide, innovative OER adoption. This application was successful in receiving the Gladys Williams Wolf Endowed Teaching Chair in Communications on Monday, April 4, 2016.

Structural Evaluation of the Optic Nerve Head.
-
Abstract/Description
-
Precise morphological evaluation of the optic nerve head is essential to accurately diagnose glaucoma, especially in diverse patient populations. Interpretation of the physical structure of the optic nerve head includes optic disc size, cup to disc ratio, vertical disc diameter and retinal nerve fiber layer thickness. I hypothesize that there are subtle differences in the optic nerve head appearance based on age, gender, race and refractive error that can predict an increased likelihood of...
Show morePrecise morphological evaluation of the optic nerve head is essential to accurately diagnose glaucoma, especially in diverse patient populations. Interpretation of the physical structure of the optic nerve head includes optic disc size, cup to disc ratio, vertical disc diameter and retinal nerve fiber layer thickness. I hypothesize that there are subtle differences in the optic nerve head appearance based on age, gender, race and refractive error that can predict an increased likelihood of glaucoma development and degree of irreversible vision loss. Detailed measurements of the optic nerve head were taken using advanced imaging technology called an optical coherence tomography (OCT). Data were analyzed using regression analysis to determine potential correlations between the impact of the physical characteristics of the optic nerve with the development of glaucoma. Individual variables were compared using ANOVA. On average, subjects with high myopia included in the study were shown to have larger disc areas than those with mild to moderate myopia and have an increased risk of developing glaucoma. In addition, patients with a positive family history of glaucoma are more likely to develop advanced versions of the disease.

Prions, Amyloid Precursor Protein, and Tau.
-
Abstract/Description
-
Prions, amyloid precursor protein (APP), and tau, and the diseases that result from them, share common characteristics. These include the manner in which the diseases progress, and the structures and physiology of the proteins. This paper discusses some common characteristics.

Pine Grove and White City Cemeteries Data Sheet.
-
Abstract/Description
-
These data were collected as part of an undergraduate anthropology course at IRSC, which was created in 2016 as a service learning opportunity introducing students to the process of anthropological research through active participation in a cemetery recording project. The cemetery recording is part of the Florida Public Archaeology Network’s (FPAN) statewide Florida Historic Cemetery Recording Project (FLHCRP) and Cemetery Resource Protection Training (CRPT).
