Show moreSimulation using computerized patient mannequins may be a useful mechanism to teach safe and effective nursing care, thus improving the quality of education for nurses. As nursing program enrollments grow, clinical placement is becoming more difficult and may not offer consistent learning opportunities that reinforce safe and effective nursing practice. This study applied Ford, Smith, Weissbein, Gully, and SalasÂÂÂÂ' (1998) model of learning transfer as the theoretical framework to design a simulated obstetric clinical learning experience to augment the current clinical practice model, an approach that may lead to an improved educational experience. The purpose of this study was to compare learning outcomes of two clinical teaching strategies for obstetric clinical content for undergraduate nursing students: standard clinical instruction and a simulation-enhanced clinical experience. A mixed-method approach was used. A randomized cluster design was chosen to compare the learning outcomes for students participating in a simulation-enhanced clinical experience versus students participating in a traditional clinical rotation. From the study population of 124 students, 40 participated in the simulation-enhanced clinical group, with the remainder of students serving as controls. Four instruments (Obstetric Nursing Self-Efficacy instrument, Goal Orientation Scale, Proxy Measure, and examination knowledge items) were used to measure student characteristics or achievement of outcomes. Learning outcomes for self-efficacy, knowledge, skills, and transfer were compared between the groups using ANCOVA, independent sample t-test, and chi-square analyses. A qualitative descriptive analysis of clinical evaluations for all students was also conducted. Demographic characteristics between the groups were not statistically different. The analysis of covariance (ANCOVA) revealed no difference in ONSE posttest scores between the groups after adjusting for goal orientation and ONSE pretest scores. An alternative ANCOVA for sequence (time in semester when the simulation occurred) and group was not significant. However, after adjustment for the covariate of ONSE pretest scores, ONSE posttest scores varied with sequencing (p <.05); students who had the simulated experience during the first half of the semester (M=67.27) scored higher than those in the second half (M=60.89) when pretest scores were used as a covariate. No differences were found between the experimental and control groups for knowledge or skills. The narrative analysis revealed broad variation in comments on the clinical evaluation form among clinical instructors. Attitude, knowledge attainment, skill acquisition, helpfulness, and professional role attributes were common themes related to student clinical performance. The findings from the study contribute to a growing body of literature evaluating the efficacy of simulation to augment clinical nursing practice experience. Data suggest there is little difference in learning outcomes for students participating in a simulation-enhanced clinical group versus the traditional clinical rotation. This finding supports that at least 15% of clinical hours could occur in a simulated clinical environment. A model driven method of simulation design and delivery could support learning in a way that will allow for efficient and effective use of simulation to support safe and effective obstetric nursing care.

Show moreThe use of military forces in urban operations has increased considerably over the past years. As illustrated by the current conflict in Iraq, the Army finds itself fighting its toughest battles in urban areas facing unconventional forces. Soldiers face many threats in hostile fire environments, whether conducting large-scale mechanized warfare, low-intensity conflicts, or operations other than war. Through 1970, there has been no demonstrable reduction in battlefield mortality rate as a percentage of all casualties since data was kept since before the Civil War. For that period of time, nearly all the reduction in overall mortality rate occurred through reduced mortality in Hospital Chain. As of 1970, about 90 percent of all combat deaths occur before a casualty reaches a definitive care facility. Tactical Combat Casualty Care (TCCC), also known as TC3, is the pre-hospital care rendered to a casualty in a combat environment. The application of TCCC principles during a tactical combat environment has proven highly effective and is a major reason why combat deaths in latest conflicts (Operation Iraqi Freedom and Operation Enduring Freedom) are lower than in any other conflict in the history of the United States. The Army continues to emphasize reducing battlefield mortality rate. Current tools and methods used for initial skills and sustainment training of combat medics throughout the Army are insufficient. New technologies are needed to provide medics with greater opportunities to develop and test their decision making and technical medical skills in multiple, COE-relevant, training scenarios. In order to address some of these requirements, the U.S. Army Research Development and Engineering Command, Simulation and Training Technology Center (RDECOM-STTC) is developing the 68W – Tactical Combat Casualty Care Simulation (TC3 Sim) for the US Army Medical Department (AMEDD) Center & School at Fort Sam Houston. The Army is considering the use of the TC3 Sim game as a tool to improve the training of individual Soldiers as well as improve the readiness of combat medics. It is the intent of this research to evaluate the effectiveness of instructional games in general and the use of the TC3 game in particular for teaching the concepts of tactical combat casualty care. Experiments were conducted to evaluate the training effectiveness of this tool in supporting the 68W10 Healthcare Specialist Course program of instruction (POI). The goal of this research is to address important questions such as: Is this game an effective tool to train Soldiers the aspects of TC3? Can knowledge gain through the use of the simulation be transferred into task related situations? How can this tool be incorporated in the current POI in order to increase training effectiveness?

Show moreThe U.S. Army Training and Doctrine Command's Army Learning Concept 2015 and Army Training Concept 2025 are documents that discuss the need for an adaptive soldier learning model with a flexible training delivery methodology. The U.S. Army has been investing in serious gaming technology for the past two decades as a cost effective means to teach tactics and strategy. Today, the U.S. Army is seeking to expand its application of virtual environment training to areas such as cultural awareness and human network analysis for the infantry soldier. These new expanded applications will require a higher level of non-determinant behavior inside the virtual environment. To meet more of the training needs of the war fighter, the U.S. Army is looking beyond first person perspective games to the cooperative and social gaming experience offered by the MMOG (Massively Multiplayer Online Game) and the VWT (Virtual World Technology). Altogether, these classes of games have the potential to teach leadership skills, social acclimation skills, cultural awareness and practice skills, and critical thinking skills for problem solving in a cost effective manner. Unfortunately, even today there is a paucity of scientific research to support whether this potential may be realized or not. A literature review was performed which covers current concepts in the usage of virtual environments for military individual and team training in the U.S. Army infantry soldier domains. There are many variables involved with the lifecycle of the virtual training activity including the acquisition, information assurance and cyber security, deployment, proper employment, content development and maintenance, and retirement. This discussion goes beyond the traditional topics of graphics and game engine technology and delves deeper into concepts of the importance of proper usage of the environments by the trainees. This dissertation is composed of three studies with two subject pools: experienced soldiers and novice soldiers. The participants in the studies were randomly assigned to one of two training conditions. The training conditions were either a traditional slide-show in a classroom or a virtual environment based training system. The participants were then provided with training for a room clearing tasks in each of the conditions. The independent variables are training condition and soldier condition. The dependent variables are individual performance, team performance, stress questionnaire scores, and workload questionnaire scores. A number of relationships are explored in this dissertation. The first objective of these studies is to attempt to identify any effect the training conditions have on either individual performance or team performance. Lastly, these studies attempt to identify if there is any difference the training conditions have on novice versus experienced subjects' performance during a live assessment.

Show moreDeterioration of road infrastructure arises from aging and various other factors. Consequently, inspection and maintenance have been a serious worldwide problem. In the United States, degradation of concrete bridge decks is a widespread problem among several bridge components. In order to prevent the impending degradation of bridges, periodic inspection and proper maintenance are indispensable. However, the transportation system faces unprecedented challenges because the number of aging bridges is increasing under limited resources, both in terms of budget and personnel. Therefore, innovative technologies and processes that enable bridge owners to inspect and evaluate bridge conditions more effectively and efficiently with less human and monetary resources are desired. Traditionally, qualified engineers and inspectors implemented hammer sounding and/or chain drag, and visual inspection for concrete bridge deck evaluations, but these methods require substantial field labor, experience, and lane closures for bridge deck inspections. Under these circumstances, Non-Destructive Evaluation (NDE) techniques such as computer vision-based crack detection, impact echo (IE), ground-penetrating radar (GPR) and infrared thermography (IRT) have been developed to inspect and monitor aging and deteriorating structures rapidly and effectively. However, no single method can detect all kinds of defects in concrete structures as well as the traditional inspection combination of visual and sounding inspections; hence, there is still no international standard NDE methods for concrete bridges, although significant progress has been made up to the present.This research presents the potential to reduce a burden of bridge inspections, especially for bridge decks, in place of traditional chain drag and hammer sounding methods by IRT with the combination of computer vision-based technology. However, there were still several challenges and uncertainties in using IRT for bridge inspections. This study revealed those challenges and uncertainties, and explored those solutions, proper methods and ideal conditions for applying IRT in order to enhance the usability, reliability and accuracy of IRT for concrete bridge inspections. Throughout the study, detailed investigations of IRT are presented. Firstly, three different types of infrared (IR) cameras were compared under active IRT conditions in the laboratory to examine the effect of photography angle on IRT along with the specifications of cameras. The results showed that when IR images are taken from a certain angle, each camera shows different temperature readings. However, since each IR camera can capture temperature differences between sound and delaminated areas, they have a potential to detect delaminated areas under a given condition in spite of camera specifications even when they are utilized from a certain angle. Furthermore, a more objective data analysis method than just comparing IR images was explored to assess IR data. Secondly, coupled structural mechanics and heat transfer models of concrete blocks with artificial delaminations used for a field test were developed and analyzed to explore sensitive parameters for effective utilization of IRT. After these finite element (FE) models were validated, critical parameters and factors of delamination detectability such as the size of delamination (area, thickness and volume), ambient temperature and sun loading condition (different season), and the depth of delamination from the surface were explored. This study presents that the area of delamination is much more influential in the detectability of IRT than thickness and volume. It is also found that there is no significant difference depending on the season when IRT is employed. Then, FE model simulations were used to obtain the temperature differences between sound and delaminated areas in order to process IR data. By using this method, delaminated areas of concrete slabs could be detected more objectively than by judging the color contrast of IR images. However, it was also found that the boundary condition affects the accuracy of this method, and the effect varies depending on the data collection time. Even though there are some limitations, integrated use of FE model simulation with IRT showed that the combination can be reduce other pre-tests on bridges, reduce the need to have access to the bridge and also can help automate the IRT data analysis process for concrete bridge deck inspections. After that, the favorable time windows for concrete bridge deck inspections by IRT were explored through field experiment and FE model simulations. Based on the numerical simulations and experimental IRT results, higher temperature differences in the day were observed from both results around noontime and nighttime, although IRT is affected by sun loading during the daytime heating cycle resulting in possible misdetections. Furthermore, the numerical simulations show that the maximum effect occurs at night during the nighttime cooling cycle, and the temperature difference decreases gradually from that time to a few hours after sunrise of the next day. Thus, it can be concluded that the nighttime application of IRT is the most suitable time window for bridge decks. Furthermore, three IR cameras with different specifications were compared to explore several factors affecting the utilization of IRT in regards to subsurface damage detection in concrete structures, specifically when the IRT is utilized for high-speed bridge deck inspections at normal driving speeds under field laboratory conditions. The results show that IRT can detect up to 2.54 cm delamination from the concrete surface at any time period. This study revealed two important factors of camera specifications for high-speed inspection by IRT as shorter integration time and higher pixel resolution.Finally, a real bridge was scanned by three different types of IR cameras and the results were compared with other NDE technologies that were implemented by other researchers on the same bridge. When compared at fully documented locations with 8 concrete cores, a high-end IR camera with cooled detector distinguished sound and delaminated areas accurately. Furthermore, indicated location and shape of delaminations by three IR cameras were compared to other NDE methods from past research, and the result revealed that the cooled camera showed almost identical shapes to other NDE methods including chain drag. It should be noted that the data were collected at normal driving speed without any lane closures, making it a more practical and faster method than other NDE technologies. It was also presented that the factor most likely to affect high-speed application is integration time of IR camera as well as the conclusion of the field laboratory test.The notable contribution of this study for the improvement of IRT is that this study revealed the preferable conditions for IRT, specifically for high-speed scanning of concrete bridge decks. This study shows that IRT implementation under normal driving speeds has high potential to evaluate concrete bridge decks accurately without any lane closures much more quickly than other NDE methods, if a cooled camera equipped with higher pixel resolution is used during nighttime. Despite some limitations of IRT, the data collection speed is a great advantage for periodic bridge inspections compared to other NDE methods. Moreover, there is a high possibility to reduce inspection time, labor and budget drastically if high-speed bridge deck scanning by the combination of IRT and computer vision-based technology becomes a standard bridge deck inspection method. Therefore, the author recommends combined application of the high-speed scanning combination and other NDE methods to optimize bridge deck inspections.
