Johnson, Mindi Lynne. "Graduate Nurse Pediatric Emergency Nursing Orientation Program." ScholarWorks, 2015. https://scholarworks.waldenu.edu/dissertations/1605.
Full textAbstract:
Research has found that the turnover rate of graduate nurses within their first year is significantly high. Specialties such as pediatric and emergency nursing have even a higher turnover rate. It has been suggested that significant amounts of stress and lack of skills are responsible for the turnovers. This quality improvement project, which is theoretically based on Benner's novice to expert theory, will examine if a lack of a specialized pediatric emergency graduate nurse orientation program is a contributing factor. The purpose of the project is to improve retention of graduate nurses by implementing a specialized orientation program that focuses on pediatric emergency nursing. The research question examined the effect of a specialized graduate nurse orientation program on increasing retention, nurses' competency, and job satisfaction. This project takes the hospital's original orientation program of 6 generalized classes and hands-on orientation and adds a more specialized approach. The Emergency Nurses Association (ENA) Core Curriculum of specialized skills and didactic classes for pediatric emergency nursing (developed by the ENA pediatric committee based on evidence and gold standard practice); evaluation tools (developed by researcher) for both the preceptor and orientee; and face-to-face meetings between the educator, preceptor and orientee were the tools used for specializing the orientation program. It is anticipated that the results will show that increase in retention. In terms of social change, it is anticipated increased nursing retention will increase nursing knowledge and job satisfaction, which will ultimately lead to improved patient outcomes and decreased mortality rates.

<p> The traditional new graduate nurse (NGN) orientation process places NGN with an experienced preceptor for 24 weeks and requires clinical skills checklists to be completed by the preceptor, a practice which is not an evidence-based practice for orienting NGNs. The purpose of this quality improvement project was to develop an evidence-based orientation to decrease time requirements and standardize the processes and evaluation of the NGN in the emergency department. The project was informed by Benner’s novice to expert theory and focused on acquisition of clinical skills. The project team included 6 stakeholders: the Doctor of Nursing Practice student-leader, the unit manager, and several preceptors and novice nurses. The current evidence was identified utilizing various search terms via OVID, CINAHL, and MEDLINE. Five emergency department nurse residency programs and 7 rubric-based criterion articles were identified and evaluated. The team synthesized the available evidence to create the program. Resulting products included guidelines, evaluation rubrics, and projected pathways for ongoing development. Content validation was undertaken using peer review by 2 nurse scholars with area expertise, after which the project team revised all products based on feedback. Together, these products comprise an evidence-based solution to the problematic orientation of NGNs in the institution’s emergency department. Adoption of methods that have proven valuable in undergraduate education, such as incorporation of syllabi and rubrics, may increase retention and improve clinical judgment in the NGN. These improved educational outcomes will, in turn, promote improved health outcomes for patients. Outcomes for the project will be monitored using retention rates and the results of the Casey-Fink Graduate Nurse Experience Survey.</p>

Full textAbstract:
UA Open Access Publishing Fund<br>Background: The transition from medical student to first-year intern can be challenging. The
stress of increased responsibilities, the gap between performance expectations and varying
levels of clinical skills, and the need to adapt to a new institutional space and culture can make
this transition overwhelming. Orientation programs intend to help new residents prepare for
their new training environment.
Objective: To ease our interns’ transition, we piloted a novel clinical primer course. We believe
this course will provide an introduction to basic clinical knowledge and procedures, without
affecting time allotted for mandatory orientation activities, and will help the interns feel better
prepared for their clinical duties.
Methods: First-year Emergency Medicine residents were invited to participate in this primer
course, called the Introductory Clinician Development Series (or “intern boot camp”), providing
optional lecture and procedural skills instruction prior to their participation in the mandatory
orientation curriculum and assumption of clinical responsibilities. Participating residents
completed postcourse surveys asking for feedback on the experience.
Results: Survey responses indicated that the intern boot camp helped first-year residents feel
more prepared for their clinical shifts in the Emergency Department.
Conclusion: An optional clinical introductory series can allow for maintenance of mandatory
orientation activities and clinical shifts while easing the transition from medical student to
clinician.

Full textAbstract:
Introduction: Acute coronary syndromes, including ST-elevation myocardial infarction (STEMI), are a leading cause of morbidity and mortality worldwide. Existing research shows that prehospital care provided by emergency medical services (EMS) can significantly improve outcomes. However, EMS remains grossly underutilised in Abu Dhabi despite a well-established presence. Objectives: In this three-part quantitative, observational study, we sought to (1) assess physicians' perceptions of, and recommendations for, utilization and improvement of EMS, (2) assess patients' awareness of EMS, mode of transport use in decision to seek care and reasons for their decision, and (3) establish if in the current study setting, mode of transport used has implications for in hospital adverse events, as well as short and long term clinical outcomes. The goal was to investigate both physicians' and patients' perceptions of prehospital STEMI care, as well as to assess the clinical correlates of the mode of transport in a patient's decision to seek care. Methods: We conducted the study in three phases. Phase 1: At four government-operated hospitals in Abu Dhabi, we administered surveys to a convenience sample of physicians involved in care of patients with acute coronary syndromes to measure (a) likelihood of recommending EMS, (b) satisfaction with EMS, (c) likelihood of using EMS for self or family, and (d) recommendations for prehospital care of acute coronary syndromes. Phase 2: We gathered mode of transport data from a purposive, non-random sample of 587 consecutive patients with STEMI over an 18-month period and conducted structured follow-up interviews to assess their perceptions of EMS. We conducted analysis to determine whether mode of transport was related to demographic variables. Phase 3: We collected medical records from patient participants and conducted structured follow-up interviews at 1, 6 and 12 months post discharge. We conducted chi square difference testing to determine the relationships among mode of transport, treatment times, and short- and long-term clinical outcomes. Variables included treatment times and associated outcomes. Results: Physician participants (n = 106) were most supportive of prehospital 12-lead ECG for STEMI, but indicated low satisfaction with existing EMS services in Abu Dhabi. Among STEMI patient participants (n = 587), EMS was underutilized in Abu Dhabi; over half (55%) of patients did not know the phone number to contact EMS, and only 14.7% used EMS in their decision to seek care. EMS-transported patients were more likely to receive timely treatment (door-todiagnostic ECG time, door-to-balloon time) and had lower incidence of mortality compared to privately-transported patients. Conclusions: These findings suggest a need to raise public awareness of EMS and its importance for coronary symptoms in Abu Dhabi. Broader application of prehospital ECG, including prehospital activation of cardiac catheterization labs, bypassing non-interventional cardiology centres, and admission directly to facilities that provide these services without initial admission to the emergency department, could help improve physicians' perceptions of EMS and outcomes for patients with STEMI.

Full textAbstract:
In multibody systems, mechanical components (bodies) can be assumed rigid (non-deformable), if their deformation is negligible. For components with non-negligible deformations several methods were developed to represent their deformation. The most widely used method is the floating frame of reference. In this formulation the deformable body is represented by a finite element model whose deformation is described with respect to a local body-fixed frame. Unfortunately, finite element models can include many degrees-of-freedom, which stand in contradiction to the requirements of multibody dynamics. System truncation is therefore inevitable to support computational efficiency. The use of modal data in representing a deformable body is well understood in the multibody community. By truncating modes associated with higher frequencies, the total degrees-of-freedom of the deformable body can be reduced while preserving its dynamic eigen-properties. However, since the finite element model may be in contact with other moving bodies, the reduction technique needs to address the issue of moving boundary conditions. The component mode synthesis reduction methods are such techniques that describe the deflection of all the nodes as a superposition of different types of modes. However, it is limited in the fact that the nodes in contact need to remain in contact throughout a simulation. In some applications these nodes may change, i.e. a node that is in contact with another body or the ground at one instant may become free at the next instant. The present methodologies in multibody modeling of a deformable body with modal data have not yet addressed the issue of changing contact nodes. This research highlights the usefulness of orientation invariant characteristics of some deformable bodies. It proposes to define orientation invariant degrees-of-freedom of the reduced model in Eulerian space, while the remaining degrees-of-freedom are defined in Lagrangian space. In some circumstances, this approach can resolve the issue of changing contact nodes. The combination of Eulerian and Lagrangian formulation for component mode synthesis reduced finite element models is a new concept in deformable multibody dynamics.

Full textAbstract:
Understanding the orientation of small organic acid modifiers on metal oxide electrodes is important in advancing the field of organic photovoltaics (OPVs). In this work, the orientation of a group of these small organic acid modifiers will be investigated on indium zinc oxide (IZO). Polarization modulation-infrared reflectance-absorbance spectroscopy (PM-IRRAS) is the primary technique used to determine these orientations. In order to determine orientations from PM-IRRAS data, other chemical and physical properties of the modifiers, such as density and surface coverage, must be experimentally determined. Neutral buoyancy is used to determine the density of the modifiers, while X-ray photoelectron spectroscopy (XPS) is used to estimate surface coverage of these modifiers on IZO. These techniques are also used to determine binding mode of these modifiers on IZO. The tilt angles (θ) were found to be 50 ± 3°, 64 ± 2°, and 43 ± 3° for F₅BnPA, F₅BnCA, and F₅BnHA, respectively, meaning that the phenyl ring in F₅BnHA is more perpendicular to the surface while the phenyl ring in F₅BnCA more parallel to the surface. All three modifiers were also found to bind to IZO in a bidentate manner. In contrast, F₅BnSA etches away significant portions of the IZO substrate.

Full textAbstract:
<p> Over 59 million US residents live in rural areas where they cannot easily access healthcare services. Well-documented disparities between rural and urban healthcare access led the federal government to certify and financially support Critical Access Hospitals (CAHs), which offer rural healthcare services and 24/7 emergency care. Many CAHs are in dire financial distress, and some are looking to increase their patient population volume to improve financial health and ensure continued operations. It is a well-known business truism that satisfied customers are return customers. Today many patients' first encounter with a hospital is with the emergency department (ED). Thus, it is likely that increasing patient satisfaction with their ED visits in a CAH can be expected to increase the chance that they will return for additional care. </p><p> All hospitals engage in quality improvement (QI) activities. Many papers outline efforts by QI teams to implement one or a few predetermined interventions with mixed results. Because patients in an ED are subject to a variety of processes in the ED and other hospital departments, improving patient satisfaction in the ED demands a comprehensive approach. This paper focuses on the QI processes and tools used by the QI team in a CAH that developed a comprehensive list of (56) short- and long-term interventions to take place over five years to improve patient satisfaction in the ED. For this hospital, two aspects of the project deserve mention: </p><p> 1. The use of Failure Mode and Effects Analysis (FMEA): The FMEA is a QI tool developed by the military to address complex problems. Although it has been adapted for use in healthcare QI, in the author's experience, it has not always been fully implemented. The QI team completed a traditional, full, two-part FMEA. In completing both parts of a traditional FMEA, the team first identified and individually analyzed each known or potential failure in the care of an ED patient and potential interventions that could prevent each failure. Then, after careful analysis of all potential interventions, the QI team chose those most likely to succeed and began implementing a sequenced schedule of interrelated interventions deemed most likely to improve care and patient satisfaction. </p><p> 2. Learner-Centered Teaching: QI projects typically use learner-centered teaching methods that, according to Social Cognitive Theory, improve participants' general self-efficacy, which is the likelihood of choosing difficult problems to solve and persisting when faced with challenges. The hospital's project team members' self-efficacy scores increased after participating on the team. Post-project interviews with team members indicate they feel better equipped to solve other problems and have begun to plan other QI projects because they understand other areas' processes, they know who should participate on projects, and they better understand QI processes and tools.</p><p>

Full textAbstract:
Emergency Departments (ED) are highly dynamic environments comprising complex multi-dimensional patient-care processes. In recent decades, there has been increased pressure to improve ED services, while taking into account various aspects such as clinical quality, operational efficiency, and cost performance. Overcrowding has become a major barrier to receiving a proper and timely emergency care in many acute hospitals throughout the world. Patients often face long waiting times to be seen and treated. Those who require admission may even wait longer. The scope of this research is to focus on ED factors that lead to overcrowding and their management. Technology is being cited as one of the management tools, specifically the utilization of Radio Frequency Identification (RFID) for tracking patients as their journey progresses through an ED. Like any technology, RFID has potential and pitfalls. The author chose to use Failure Mode and Effect Analysis (FMEA) as a tool to explore the possible failures of RFID technology as it is utilized in one of the ED in Riyadh Military Hospital (RMH). This particular ED has been used as a case study to explore those failures and, with the use of FMEA, propose a set of recommendations to address those failures and improve the design and implementation of RFID. The experience of RMH-ED was explored through interviews and a survey in which 100 participants took part. The survey touched upon various aspects of this experience. This was due to the various roles of the surveyed staff who were involved with this technology. These roles ranged from front line clinical staff to administrative staff, management staff and technical support staff. Data analysis showed convincing evidence of the positive impact RFID had on managing ED overcrowding. However, and as expected, there are some pitfalls and failures that FMEA helped identifying and suggested potential solutions to them. RFID is a small link in the chain of other technological innovations and solutions. It is by no means capable of solving the problems associated with ED overcrowding by itself. Most of the search carried out by the author identified large variation in approaches to dealing with the issue of ED overcrowding. Those ranged from applying more human resources to altering the pathways of managing patients journey through healthcare system to applying more intermediate layers of management to ease the pressure of the Emergency departments. Other approaches included some aspects of technology such as development of early warning systems that have not been widely adopted and remained as isolated efforts.

Full textAbstract:
The primary focus of this thesis was to investigate the critical strain energy release rates (G) for mixed-mode (I/II) fracture of wood adhesive joints. The aims of the study were: (1) quantifying the fracture properties of two material systems, (2) analyzing the aspects that influence the fracture properties of bonded wood, (3) refining test procedures that particularly address layered orthotropic systems in which the layers are not parallel to the laminate faces, of which wood is often a particular case, and (4) developing testing methods that enhance the usefulness of performing mixed-mode tests with a dual-actuator load frame. The material systems evaluated experimentally involved yellow-poplar (Liriodendron tulipifera), a hardwood of the Magnoliaceae family, as adherends and two different adhesives: a moisture-cure polyurethane (PU) and a phenol/resorcinol/-formaldehyde (PRF) resin. The geometry tested in the study was the double cantilever beam that, in a dual-actuator load frame, can be used for testing different levels of mode-mixity. The mixed-mode loading condition is obtained by applying different displacement rates with the two independently controlled actuators of the testing machine.
Characteristic aspects such as the large variability of the adhesive layer thickness and the intrinsic nature of many wood species, where latewood layers are alternated with earlywood layers, often combine to confound the measures of the critical values of strain energy release rate, Gc. Adhesive layer thickness variations were observed to be substantial also in specimens prepared with power-planed wood boards and affect the value of Gc of the specimens. The grain orientation of latewood and earlywood, materials that often have different densities and elastic moduli, limits the accuracy of traditional standard methods for the evaluation of Gc. The traditional methods, described in the standards ASTM D3433-99 and BS 7991:2001, were originally developed for uniform and isotropic materials but are widely used by researchers also for bonded wood, where they tend to confound stiffness variations with Gc variations. Experimental analysis and analytical computations were developed for quantifying the spread of Gc data that is expected to be caused by variability of the adhesive layer thickness and by the variability of the bending stiffness along wooden beams.<br>Ph.

Full textAbstract:
La peau est un organe particulier de l'organisme dont la fonction principale est un rôle de protection vis-à-vis du milieu extérieur. Cette fonction est assurée grâce à la structure du tissu cutané en trois couches (épiderme, derme, hypoderme). Le derme est responsable de la résistance et de la souplesse de la peau. Le composant moléculaire majeur du derme est le collagène de type I, qui est fortement altéré au cours du vieillissement chronologique. Dans ce contexte, notre étude a pour objectif d'évaluer les modifications moléculaires du collagène dermique associées au vieillissement cutané par spectroscopies vibrationnelles (diffusion Raman et absorption infrarouge). Par déconvolution de la bande Amide I du signal Raman, nous avons mis en évidence, en fonction de l'âge de la peau, des modifications au niveau des interactions entre le collagène et les molécules d'eau ; ce qui reflète un espacement croissant des faisceaux de fibres de collagène au cours du vieillissement. En micro-imagerie infrarouge polarisée, le ratio des bandes Amide I/ Amide II permet d'évaluer l'orientation des fibres de collagène qui deviennent parallèles à la surface de la peau lors du vieillissement. Des expérimentations préliminaires ont également montré la possibilité de localiser sans marquage la jonction dermo-épidermique de la peau grâce aux caractéristiques spectrales du collagène de type IV. Une analyse ciblée de cette structure nécessite de développer de nouveaux instruments basés sur la spectroscopie en champ proche (Tip Enhanced Raman Scattering, NanoIR) ; ce qui devrait permettre de suivre les altérations du collagène de type IV au cours du vieillissement cutané<br>Skin is a particular organ of the body whose the main function is a protective role towards the external environment. This function is provided by the structure of skin tissues in three layers (epidermis, dermis, hypodermis). The dermis is responsible for the strength and elasticity of the skin. The major molecular component of the dermis is the type I collagen, which is strongly altered during chronological aging. In this context, our study aims at evaluating the molecular modifications of the dermal collagen associated with skin aging by vibrational spectroscopy (Raman diffusion and infrared absorption). Using curve-fitting of Raman Amide I band, modifications in the interactions between collagen and water molecules were highlighted depending of the donor age. Such result reflects an increasing spacing of the collagen fiber bundles during aging. In addition, the collagen fibers orientation can be evaluated from the amide I/ amide II ratio calculated in polarized infrared micro-imaging. It appeared that the collagen fibers become orientated parallel to the skin surface with aging. Preliminary experiments showed also the ability to localize in a label-free manner the dermo-epidermal junction of the skin using the spectral characteristics of type IV collagen. A precise analysis of this structure requires the development of new instruments based on near-field spectroscopy (Tip Enhanced Raman Scattering, NanoIR); which could permit to follow the collagen IV alterations during skin aging

Les travaux de recherches sur la commande, le diagnostic et la tolérance aux défauts appliqués aux drones deviennent de plus en plus populaires. Il est judicieux de concevoir des lois de commande qui garantissent la stabilité et les performances du drone, non seulement dans le cas nominal, mais également en présence de fortes perturbations et de défauts.Dans cette thèse, un nouvel algorithme bio-inspiré adapté pour la recherche de solutions dans des problèmes d’optimisation est développé. Cet algorithme est utilisé pour trouver les gains des différents contrôleurs conçus pour les drones. La commande par mode glissant est utilisée pour développer deux contrôleurs passifs tolérants aux défauts pour les quadrirotors: un contrôleur par mode glissant augmentée avec un intégrateur, et un contrôleur par mode glissant implémenté en cascade. Parce que les commandes passives ont une robustesse réduite, une commande active par mode glissant est développée. Pour traiter les défauts extrêmes, un contrôleur d’urgence basé sur la conversion du quadrirotor en trirotor est développé. Les commandes actives, passives, et le contrôleur d’urgences sont ensuite intégrés pour former un contrôleur tolérant aux défauts capable de gérer un grand nombre de défaillances tout en garantissant les ressources actionneur et en limitant la charge de calcul du processeur. Finalement, des contrôleurs tolérants aux défauts, actifs et passifs, basés sur des méthodes par mode glissant du premier et deuxième ordre sont développées pour les octorotors. La commande active utilise des méthodes d’allocation de contrôles pour redistribuer les efforts sur les actionneurs sains, réduisant ainsi l’effet du défaut<br>Unmanned Aerial Vehicles (UAV) are more and more popular for their civil and military applications. Classical control laws usually show weaknesses in the presence of parameter uncertainties, environmental disturbances, and actuator and sensor faults. Therefore, it is judicious to design a control law capable of stabilizing the UAV not only in the fault-free nominal cases, but also in the presence of disturbances and faults. In this thesis, a new bio-inspired search algorithm called Ecological Systems Algorithm (ESA) suitable for engineering optimization problems is developed. The algorithm is used over the thesis to find optimal gains for the fault tolerant controllers. Sliding Mode Control theory is used to develop two Passive Fault Tolerant Controllers for quadrotor UAVs: Regular and Cascaded SMC. Because Passive Controllers handle a few numbers of faults, an Active Sliding Mode Fault Tolerant Controller using Kalman Filter is developed. To overcome severe faults and failures, an emergency controller based on the Quadrotor-to-Trirotor conversion maneuver is developed. The Controllers developed so far (Passive, Active, and emergency controllers) are then integrated to form the Integrated Fault Tolerant Controller (IFTC). The IFTC is a powerful controller that is able to handle a wide number of faults, and save actuator resources as well as processor computational effort. Finally, Passive and Active Fault Tolerant Controllers are designed for octorotor UAVs based on First Order and Second Order Sliding Mode Control. The AFTC uses Dynamic and Pseudo-Inverse Control Allocation methods to redistribute the control effort among healthy actuators reducing the effect of fault

La justice pénale française connait une diversification des modes de traitement des affaires qui lui sont soumises. Cette diversification résulte de facteurs endogènes et exogènes au système lui-même. Elle est le point de convergence de l'évolution des conceptions des phénomènes criminels, des attentes sociales pour une justice pénale efficace et, d'un nouveau mode de gestion de la justice. Les modes de poursuite traduisent une de logique de politique criminelle et, une logique de rationalisation du mode de management de la justice pénale. La notion de «modes de poursuite» devient une nouvelle catégorie juridique qui structure le traitement des délits. Sa portée théorique modifie l'approche de la poursuite. La diversification des modes de poursuite a des incidences sur la conception et la typologie du procès pénal et sur l'organisation des juridictions. Le procès pénal monolithique hérité du code d'instruction criminelle de 1808 devient un procès pluriel ayant une physionomie renouvelée et des finalités multiples. La poursuite pénale répond à des principes directeurs nouveaux ou renouvelés. La notion de «schéma d'orientation» illustre cette évolution. Une prise en compte législative de cette notion déboucherait sur une meilleure structuration de la réponse pénale. L'organisation de la chaîne pénale est également affectée, ainsi que la place des acteurs du procès. Des mécanismes de concertation et de délégation sont apparus. Le nouveau management judiciaire trouve appui sur cette diversification des modes de poursuite. Le procès pénal doit intégrer la transformation numérique qui devrait aboutir à la construction d'un procès pénal numérique<br>The French criminal justice currently goes through a diversification of cases treatment processes. This diversification is the result of many factors, both endogenous and exogenous. It is the focal point of the evolution in theoretical approaches regarding criminal phenomena, social expectations of an effective criminal justice, and of a new process of justice management. Prosecution choices reflect a logic of criminal policy and also a logic of rationalization of the criminal justice management. The idea of «prosecution choices» becomes a new legal category that articulates the response to criminality. Its theoretical range modifies the approach of the prosecution. The diversification of prosecution choices has consequences on both conception and typology of the criminal trial and on courts organisation. The monolithic criminal trial inherited from the 1808 French code of criminal investigation becomes a more plural trial, with a renewed configuration and multiple purposes. The notion of « orientation schematics » illustrates such evolution. A legislative consideration of this notion would lead to a better structuring of the criminal justice response. The criminal justice system's organization is also affected, as well as the parties situation in the trial. Consultation and delegation mechanisms appeared. The new judicial management builds on this diversification in the prosecution choices. The criminal trial must integrate the digital transformation that should lead to the construction of a digital criminal trial

Full textAbstract:
The present work falls within a wider framework concerning the prediction of the mechanical response of short glass fiber-reinforced thermoplastics (SFRT), which are commonly employed in the automotive industry to reduce the overall weight of the components. More in detail, the main objective of the thesis is to develop a fatigue criterion for predicting the effect of different factors affecting the fatigue strength of such materials. In this interest, the influence of the composite complex morphology (local fiber orientation and fiber content) and of notches giving rise to stress concentrations is taken into account. In the present thesis, an experimental activity related to plain and notched specimens is firstly presented. In this context, data resulting from computed tomography (CT) analyses are shown. The latter serve to evaluate the specimens’ fiber orientation distributions, which are quantified by means of fiber orientation tensors (FOT). Furthermore, fatigue test data on the considered coupons, in the absence and in the presence of notches (with radii of 0.1 mm, 0.2 mm, 2 mm and 5 mm), are presented for different fiber orientations and weight fractions (15 wt%, 25 wt%, 35 wt% and 50 wt%). Secondly, being aware of the fact that the onset of a macroscopic crack is driven by the evolution of damage at the matrix level, a multiscale fatigue model relying on matrix stress distributions is presented. The calculation of the matrix stress cumulative distribution functions is achieved by formulating an analytical numerical pseudo-grain approach (i) permitting to avoid the generation, mesh and solution of complex microstructures, but only relying on the solution of simple unidirectional cells. The pseudo-grain method is subsequently included in the formulation of a fatigue criterion, for plain (ii), at first, and for notched specimens (iii), subsequently. The proposed fatigue criterion is eventually validated with a bulk of experimental data, partially presented in this work. Namely, fiber orientation tensors are used to properly assign the anisotropic elastic properties to the developed numerical models and the presented fatigue data are employed to assess the efficacy of the model in terms of fatigue strength prediction.<br>Questa tesi di dottorato di ricerca si inserisce all’interno di un quadro più ampio relativo alla previsione del comportamento meccanico di materie termoplastiche rinforzate con fibre corte di vetro. Tali materiali compositi sono spesso impiegati nell’industria automobilistica per ridurre il peso complessivo della componentistica coinvolta. L’obbiettivo principale di questo lavoro è legato alla necessità di sviluppare criteri di cedimento che prevedano l’influenza di diversi fattori sulla resistenza a fatica di tali materiali. In particolar modo, si è scelto di focalizzarsi sull’effetto della morfologia (orientazione locale e contenuto di fibre) e della presenza di intagli, che a loro volta danno luogo a concentrazioni tensionali. In questa tesi viene presentata innanzitutto l’attività sperimentale svolta. Ovvero si riportano dati relativi ad analisi ottenute tramite tomografia computerizzata (CT). Quest’ultima ha il ruolo di fornire informazioni sulle distribuzioni locali dell’orientazione delle fibre, le quali vengono quantificate tramite il tensore di orientazione delle fibre (FOT). Inoltre, si presentano dati relativi al comportamento a fatica di provini con e senza intagli (di raggio pari a 0.1 mm, 0.2 mm, 2 mm e 5 mm), considerando contemporaneamente l’effetto dell’orientazione delle fibre e delle loro frazioni di peso (15 wt%, 25 wt%, 35 wt% e 50 wt%). In secondo luogo, consapevoli del fatto che l’origine di cricche macroscopiche può essere imputata all’evoluzione del danneggiamento nella matrice, si propone un modello multiscala per la previsione della vita a fatica di tali compositi, basandosi sul calcolo delle distribuzioni tensionali locali. Il calcolo delle funzioni cumulate delle tensioni matriciali è ottenuto tramite la formulazione di un approccio analitico-numerico di tipo pseudo-grain (i). Quest’ultimo permette quindi di evitare la generazione, mesh e risoluzione di microstrutture complesse e di ottenere i risultati desiderati tramite semplici modelli numerici unidirezionali. Tale approccio viene poi inserito nella formulazione di un criterio di fatica per provini lisci (ii) e intagliati (iii). Il criterio proposto è poi validato con un numero consistente di dati sperimentali, parte dei quali è presentata in questo lavoro. In particolare, i tensori di orientazione delle fibre sono impiegati per assegnare le proprietà elastiche anisotrope ai modelli numerici. I dati di fatica sono invece utilizzati per verificare l’efficacia del modello in termini di previsione della resistenza a fatica di provini lisci e intagliati.

Insufficient experience in emergency planning and insufficient fire protection are part of the problems. At present the length of Taipei underground railway has reached more than 15 km. The study of smoke management and evacuation shall thoroughly be performed for the longer tunnel. In case of train fire in a double-track tunnel, the topic of escaping from the nearby non-fired track across the scene of fire to reduce the escaping distance and the harmful effects should be considered for various fire intensities. The evacuation should also be considered along with the emergency mode of tunnel ventilation.
This study examines and compares the critical air velocity with the field measured data under an emergency operating mode. The NIST developed FDS (Fire Dynamics Simulator) program was used to simulate and analyze the smoke flow and other fire conditions. This study examines the computer calculation results on the basis of NFPA130. Proper recommendation for safe refuge is proposed. In addition, the calculation of safety time for safe passage across the scene of fire for various fire scenarios. The smoke management for the operation and security of long underground railway tunnel is discussed and analyzed. The results of this study could be used as a reference for planning, designing and constructing the underground railway project.

Although the superiority of metaphors over literal messages is usually explained by enhanced elaboration, little is understood with regard to whether metaphors invite readers to mentally visualize healthcare messages. It also remains unknown if different metaphor formats (abstract versus concrete) activate different processing mechanisms. In addition, there has been no attempt to examine the combination of metaphors and other healthcare communication strategies.<br>This dissertation contributes to this body of knowledge by providing a comprehensive framework focused on two different metaphor formats (abstract versus concrete). In a series of studies, this dissertation demonstrates that concrete metaphors, when compared with abstract metaphors, are usually processed via higher imagery processing. As a result, concrete metaphors are often more effective than abstract metaphors. However, abstract metaphors are more effective in encouraging behavioral persistence. In addition, congruency between metaphor format and processing instructions/temporal orientation priming enhances message effectiveness. After a certain period of time, the effect of congruency between metaphor format and temporal orientation priming fades away for risk perception, but it remains fairly strong for behavioral intention.

In order to drive the sun shading board module be operated at optimal angle, the control interface has be established by Visual Basic language with the measurement date of solar orientation. The experimental data indicate that when the initial angle of sun shading board is 25 degrees, the indoor environment is not only comfortable and circulated but also sun-shaded. When the angle is changed to 45 degrees, the module can provide not only a rain-preventing condition but also a natural ventilation indoor environment. In 90 degrees, the largest of range of vision has demonstrated. When the angle be adjusted to largest angle, it is successful to improve indoor brightness because the characteristic of light guide by itself. By the result, it is helpful to develop an optimal indoor lighting control module for improving the living environment more comfortable and energy saving and achieving the target of living technology.

Full textAbstract:
碩士<br>國立嘉義大學<br>資訊工程學系研究所<br>95<br>Comparing to the previous coding standard, H.264 provides many schemes for improving the encoding result. One of the improving scheme is mode decision. Mode decision provides different block sizes (16x16,16x8,8x16,8x8,8x4,4x8, 4x4) to suit different video property. By the way, H.264 standard can save coding bits and gains a better video quality at the same time. On the contrary, the mode decision scheme makes coding complexity increase by times. The goal of this study is to maintain the compression quality and efficiently reduce the mode decision complexity.
In our mechanism, the effectiveness is focused on the concise utilization to the coding modes of two neighbors of an encoding MB to predict its coding mode with few candidates. This depends on two cognitions in the observation of splitting seams partitioning MB for ME. The first cognition will realize the splitting seam in the prediction MB as the type of boundary of needing consecutive stretch once again between two distinct textures. This cognition holds only under the condition that the direction of splitting seam and the direction of prediction MB’s location relative to encoding MB are same. Thus, according to the nature of boundary extending, the mechanism can choose the suited candidates from all coding modes available in H.264. On the contrast, if the direction of splitting seam and that of prediction MB’s location relative to encoding MB are perpendicular, the splitting seam in prediction MB is conceived with the second cognition. From the aspect of second cognition, the splitting seam behaves like a watershed to identify two regions of displaying different textures.
In this study, we use two cognitions to predict candidate coding modes. We success reduce the complexity of coding mode decision mechanism with small influence of compression quality.

This thesis regard firefighter of Taiwan as research object. A total of 121 questionnaires were randomly selected for questionnaire survey, and the effective sample was 119. The surveyed information was analyzed by descriptive statistics, reliability analysis, mean and standard deviation, independent sample t-test and single factor-variable analysis. The study obtained the following conclusions:
1. In terms of the quality of pre-hospital care, the item “5 points, average value 4.61” is the highest score in the “EMT well keep the patient under observation on the way to emergency room”.
2. In terms of the quality of pre-hospital care, the item “5 points, average value 2.73” is the lowest score in the “suctioning of patients with respiratory noise”.
3. In the ambulance service shift mode, the ambulance deputy classes with different number of rotation hours are sent to the pre-hospital ambulance quality to "send a comfortable posture to the patient" and "confirm whether the patient's peripheral circulation is good and give corresponding treatment" There is a significant difference between the two, where a particular longer time performance is better than a short time schedule.
4. In the ambulance service shift mode, the number of different attendance ambulances is significantly different in the project of “moving patients to the ambulance, often overlooking changes in environmental safety conditions”. More than two ambulance attendance units perform better than single unit.
5. Through statistical analysis, there was no significant variability in the number of ambulance service cases.
6. The choice of ambulance personnel for the location of the injured and the location of the medical treatment will be affected by the number of ambulance cases and the time of the nearby shift, and there is a significant negative correlation.
7. In terms of personal background context, different firefighting seniority have a significant difference in the “suctioning of patients with respiratory noise”, and the specific long-term performance is better than that of new recruits.
Based on the statistical analysis results, the conclusions of this study are as follows:
1. The daily 24-hour ambulance service is divided into 3-4 time slots. The regular staff on the day is fixed for the late-night service hours. The rest of the time is executed by the fixed personnel in turn, and the monthly service schedule is announced first.
2. In the ambulance training that is regularly scheduled monthly, the actual operation equipment and situational processes are practiced, and the unskilled steps are practiced, and each person is required to take turns in rotation regardless of the amount of seniority.
3. For the special ambulance situation, increase the number of exercises, and please actually share the experience of colleagues in similar cases, and explain the cause of the ambulance or how to find the abnormality of the patient.

the Oregon State University APEX facility during test NRC-10. This test simulated a one-inch
diameter cold leg break with a failure of three of four of the fourth-stage Automatic
Depressurization System (ADS) valves. The result was a high vapor flow rate through
ADS 1-3, that caused CCFL in the pressurizer surge line and liquid holdup in the
pressurizer. Because this liquid was not available for core cooling, further study of the
passive safety systems in the AP600 under Mode 5 Cold Shutdown conditions was
deemed necessary. An analysis of the AP600 geometry and the existing CCFL database
determined that Kutateladze scaling is appropriate for the APEX and AP600 surge lines.
The Kutateladze CCFL correlation was used to assess CCFL in the APEX and AP600
pressurizer surge lines under Mode 5 Cold Shutdown conditions. The results indicate that
CCFL would be expected in the pressurizer surge lines at low pressures and decay powers
prior to ADS 4 actuation. Test NRC-35 examined CCFL and provided data to benchmark
NRC's thermal hydraulic analysis codes. This thesis presents the results of test NRC-35
and the supporting CCFL calculations.<br>Graduation date: 1999

Full textAbstract:
碩士<br>國立中山大學<br>企業管理學系醫務管理碩士班<br>107<br>Fall incidents are a common patient safety problem in emergency rooms. Such incidents cause patients to experience physical wounds, prolong their hospitalization, increase their likelihood of early death, and impose additional burdens to their family members. In addition, fall incidents can potentially lead to medical disputes and undesirable physician–patient relationships.
The fall occurrence rate is a crucial indicator for maintaining healthcare quality in hospitals. To prevent fall incidents, various hospitals have adopted root cause analysis on the fall incidents of patients of different sexes. However, few hospitals have inspected the shortcomings in their fall prevention procedures. This study adopted the healthcare failure mode and effect analysis (HFMEA) to examine the fall prevention standard operation procedure (SOP) of an emergency room , identify shortcomings in the procedure, and develop improvement strategies to address related problems.
A retrospective research design was employed to analyze the fall occurrence rate in the emergency room between 2013 and 2017, and the results revealed that this figure was higher than the hospital threshold (0.1%). The research team of this study used the HFMEA to examine the fall prevention SOP and identified 8 failure modes and 25 failure causes. Under the supervision of the emergency room director, the research team formed a cross-department fall prevention team to execute related prevention measures and response strategies. These included fall prevention consensus training, cross-department fall prevention consultation, home visit services for emergency room patients with high risks of falling, and telerehabilitation home services for emergency room patients with high risks of falling. Statistics before, during, and after the implementation of related measures were compiled over a course of 1 year. This reduced the number of fall incidents from 14 in 2017 to 3 in 2018, yielding an occurrence rate below the hospital threshold. Through improvement to the fall prevention SOP and cross-department collaboration, this study successfully reduced the fall occurrence rate of an emergency room and enhanced the patient safety and healthcare quality.

碩士<br>銘傳大學<br>公共事務學系碩士在職專班<br>97<br>The advanced information technology renders the pervading employment of computer information system in medical institutions; therefore, medical information systems integrate closely with medical services procedures in hospitals. Consequentially, examinations, diagnoses, therapies, operating procedures and application for national health insurance all depend greatly on computer information system; moreover, there will be the promotion of e-anamnesis planned. Once the information computer interrupts, it will impact severely both patients and workers, and definitely affect the hospital’s fame and cause the financial loss. However, information interruption relates closely to the impact on the operating procedures, so it is hard to locate the damaged key procedures so as to prepare for either disaster reduction or emergency strategy if there is no systematic hazard analysis available. On the other hand, the failure mode and effect analysis (FMEA) is frequently used in the industrial field whereas the use for the crisis management or patients’ safety is still in the initial phase.
Through FMEA, a case of computer interruption in a large hospital in Taipei City is inquired to probe into the procedures of hazard risk assessment & analysis of the computer interruption in outpatient services and emergency rooms. The study is done in the following steps. First, the FMEA team founded collects the data of medical operating flow and computer interruption emergency procedures in the hospital via deep interviews; afterwards, the FMEA team will define the steps and the potential failure mode, cause and impact of computer interruption. Moreover, FMEA tools are used to conduct the hazard risk assessment so as to locate the high-risk key problems in terms of ranking of risk priority number (RPN). Finally, the adequate advices and improvement measures of the high-risk operating procedures via focus-group interview are proposed as the references to the preparation for disaster prevention and emergency strategy in medical institutions.
The paper contributes to the emergency management in medical institutions via analyzing hazards by FMEA. As for the preparation for disaster prevention and reduction, it is applicable to locate the hazardous origin of computer interruption to medical operating procedures, judge the key problem of hazards and build the priority of disaster reduction and prevention. As for the disaster emergency preparation, it is applicable to implement the execution of emergency strategy by planning it under the results of hazard analysis and enforcing the personnel drill training in lights of it. The hazard analysis via FMEA is a practical and beneficial measurement tool for hospital emergency management.

碩士<br>逢甲大學<br>建築所<br>98<br>Although safety containment in hospitals is designed according to the building codes in Taiwan, there is a lack of considerations of different patients’ physical conditions, suitable fire escape apparatus and whether there is sufficient space in the safety containment. Moreover, if the planning of the architectural safety containment does not work together with the rescue policy of a hospital, rescue would not be achieved effectively, fire escape facilities would be useless, and fire rescue drill would be a waste of time. Do fire escape facilities and safety containment meet the needs of patients? Do nursing staffs help patients correctly and fast enough when fire occurs? What are nursing staffs’ knowledge of rescue mode, fire escape circulation and safety containment? These issues are going to be investigated in this research.
The first part of the research was concentrated on the field investigation of the studied hospitals, including interview, corridors of wards, fire escape circulation and rescue mode, to find out the square footage of safety containment and locations of fire escape apparatus. The second part was to take part in fire rescue drill of the studied hospitals. Rescue mode, fire escape circulation and the use of safety containment were observed and analyzed. The third part was to conduct surveys. The questionnaire consisted of four parts – rescue policy, fire escape circulation, fire escape apparatus and the use of safety containment. Finally, the problems of fire escape in the wards were found out through crosstab analysis. The differences between rescue mode practiced by nursing staff and rescue policy made by hospital were acknowledged. And suggestions regarding to the above problems were made.
The results showed that different specialties in a hospital had different needs for safety containment. Because of the action capabilities – patients in surgical specialty could walk by themselves with guarding of nursing staffs, patients in internal medicine could not - the differences and needs in each specialty had to be take into account of design of the safety containment to avoid putting patients in danger.

碩士<br>國立屏東科技大學<br>高階經營管理碩士在職專班(EMBA)<br>96<br>Due to the rapid changes of the internal and external environment of the enterprise, the competition of the enterprise is now more competitive than before. And therefore, it is an imperious study of how the enterprise holds inner value and competitive advantage. Innovation is the essential factor of maintaining advantage in the competition. In the past literature review, innovative studies are more emphasized on the factors of innovating products or factors that affect the innovation climatically. The studies of antecedent variables of organizational innovation are all too narrow. And therefore, the study would be integrated the organizational climate, total quality management, business operation mode and learning orientation which are major antecedent variables to influence organizational innovation and the performance of business. Also, to study the relationship between the organizational innovation and to try to find out the complete understanding of the context.

Indiana University-Purdue University Indianapolis (IUPUI)<br>Linking the new institutionalism to entrepreneurial orientation (EO), my dissertation investigates institutional forces and entrepreneurial forces—two contradicting types of forces—as main effects and moderating effects upon practices and performance of organizations embedded in the institutional duality. The case chosen observes unique hybrid funders that this study collectively calls social investment funders (SIF), which integrate philanthropy and venture capital investment to create and implement a venture philanthropy model for a pursuit of their mission. A theoretical framework is developed to propose regulative and normative pressures from two dominant institutions governing SIFs. Original data collected from 146 organizations are scrutinized by moderated multiple regressions for two empirical studies: Study 1 for effects on SIFs’ venture philanthropy practices, and Study 2 for effects on SIFs’ social and financial performance. Multiple imputations, diagnostic analyses, and several post hoc analyses are also conducted for robustness of data and results from multiple regression analyses.
Results from these analyses find that EO and venture capital institutional forces both enhance SIFs’ venture philanthropy practices. A hypothesis postulated for a negative relationship between the nonprofit status and venture philanthropy practices is also supported. Results from moderated regression analyses, along with a subgroup and EO subdimension analyses, confirm a moderating effect between EO and the nonprofit status, i.e., a regulative institutional pressure. A positive relationship is found in EO- financial performance, but not in EO-social performance. While support is lent to hypotheses posited for a social/financial performance relationship with donors’/investors’ demand for social outcomes, and with the management team’s training in business, the overall results remain mixed for Study 2. Nonetheless, this dissertation appears to be the first study to theorize and test EO as a micro-level condition enabling organizations to strategically shape and resist institutional pressures, and it reinforces that organizations’ behavior is not merely a product of their passive conformity to environmental forces, but of the agency, also. As such, this study aims to contribute to scholarly efforts by the “agency camp” of the new institutionalism and EO, answering a call from the leading scholars of both EO (Miller) and the new institutionalism (Oliver).

La recherche biomédicale réalisée en situation d'urgence traduit la confrontation entre
différents principes conducteurs éthiques. Le respect de l'autonomie de la personne, illustré à
travers l'obtention du consentement libre et éclairé du sujet pressenti, peut sembler un
concept vide de sens dans le cas des malades présentant une condition médicale critique. Pour
ces patients en proie à une crise médicale, et donc vulnérables, une protection individuelle
accrue s'impose. Une surprotection irait, toutefois, à la fois à l'encontre du principe de justice
distributive et du principe de bienfaisance, impliquant de ne pas exclure totalement un groupe
de sujets des expectatives élevées de bénéfices d'une recherche correctement balisée. Ce texte
a pour objectif de cerner quel est le fondement - éthique - des textes législatifs,
réglementaires et normatifs qui permettent l'enrôlement de ces malades atteints de
pathologies foudroyantes dans des protocoles de recherche, alors même qu'aucun
consentement, qu'il soit autonome ou substitué, n'a été donné. Inspirée du modèle de
réflexion éthique pluraliste, l'auteur pose comme hypothèse que c'est le principe de justice
distributive qui sous-tend la politique éthique de tels textes, puisque contribuant au
développement des avancées thérapeutiques en urgence et à la nécessité d'augmenter
l'efficacité des traitements disponibles. Ce texte cherche finalement à définir une démarche
d'approbation des protocoles de recherche qui seront réalisés en situation d'urgence.<br>Biomedical research performed under emergency conditions highlights the conflict between
competing ethical principles. The respect for the autonomy of the person, illustrated by the
need to obtain a subject's informed consent, can seem an empty concept in the case of a
patient presenting severe medical conditions. For those patients in a midst of a medical
crisis, and therefore vulnerable, particular protection is necessary. An overprotection would,
however, contravene both the principles of distributive justice and of beneficence, principles
that hold that an entire group of subjects ought not to be excluded from the expectations of
the benefits of properly controlled research. The object of this text is to discem the ethical
foundation of the legislative, regulatory and normative texts that permit those stricken with
devasting diseases to participate in research projects without consent having been granted.
Based on the pluralist ethical model, the author asserts as a hypothesis that it is the principle
of distributive justice which supports the ethical policies underlying such texts, since
contributing to the development of therapeutic advances in emergencies and to the necessity
of increasing the effectiveness of available treatments. This text attempts ultimately to
establish procedures to be followed in obtaining approval in research projects in the case of
an emergency.<br>"Mémoire présenté à la Faculté des études supérieures en vue de l'obtention du grade de maîtrise en droit option Droit et Biotechnologies". Ce mémoire a été accepté à l'unanimité et classé parmi les 15% des mémoires de la discipline.
