In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis. The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included. The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors.Inom elektronikbranschen, exempelvis vitvarutillverkare är effektstyrning av ACmotorer vanligt förekommande. Det kan handla om effektstyrning av en diskmaskinsmotor, en dammsugarmotor eller en tvättmaskinsmotor. Företaget Rejlers ingenjörer AB har flera gånger fått uppdrag där effektstyrning av AC-motorer ingått och har behov av ett prototypkort för detta som ska kunna återanvändas i framtida projekt för att spara tid och pengar. Effektstyrningen av motorerna sker med hjälp av en triac och styrning av tändpulserna till denna triac. Detta kort är modulärt uppbyggd så att det enkelt kan anpassas till framtida projekt där effektstyrning av AC-motorer ingår. Prototypkortet kan användas som ett delsystem i ett större elektronikprojekt eller i labbmiljö för test och utvärdering av nya motorer.

Full textAbstract:
Soil moisture is an important element in hydrological land-surface processes as well as land atmosphere interactions and has proven useful in numerous agronomical, climatological and meteorological studies. Since hydrological soil moisture estimates are usually point-based measurements at a specific site and time, spatial and temporal dynamics of soil moisture are difficult to capture. Soil moisture retrieval techniques in remote sensing present possibilities to overcome the abovementioned limitations by continuously providing distributed soil moisture data atdifferent scales and varying temporal resolutions. The main purpose of this study is to derive soil moisture estimates for the Stockholm region by means of two different approaches from a hydrological and a remote sensing point of view and the comparison of both methods. Soil moisture is both modelled with the Topographic Wetness Index (TWI) based on digital elevation data and with the Temperature‐Vegetation Dryness Index (TVDI) as a representation of land surface temperature and Normalized Difference Vegetation Index (NDVI) ratio. Correlations of both index distributions are investigated. Possible index dependencies onvegetation cover and underlying soil types are explored. Field measurements of soil moistureare related to the derived indices. The results indicate that according to a very low Pearson correlation coefficient of 0.023, nolinear dependency between the two indices existed. Index classification in low, medium and high value categories did not result in higher correlations. Neither index distribution is found to berelated to soil types and only the TVDI correlates alongside changes in vegetation cover distribution. In situ measured values correlate better with TVDIs, although neither index is considered to give superior results in the area due to low correlation coefficients. The decision which index to apply is dependent on available data, intent of usage and scale. The TWI surface is considered to be a more suitable soil moisture representation for analyses on smaller scaleswhereas the TVDI should prove more valuable on a larger, regional scale. The lack of correlation between the indices is attributed to the fact that they differ greatly in their underlying theories. However, the synthesis of hydrologic modelling and remote sensing is a promising field of research. The establishment of combined effective models for soil moisture determination over large areas requires more extensive in situ measurements and methods to fully assess the models’ capabilities, limitations and value for hydrological predictions.

Full textAbstract:
This application is for the U.S. Department of Education’s Education Innovation and Research Program to secure funding for a market analysis to gauge the interest of Portland, Oregon parents for opening a two-way immersion (TWI) Romanian-American bilingual public charter school. Initial conversations with members of the Romanian community in the Portland area indicate that such interest may exist. A formal survey of that community has not yet been conducted to firmly establish the potential market for such a school. Moreover, there is evidence to document that such an educational option could increase the academic achievement of English Language Learners from Underrepresented Languages (ELL-UL). Some English Language Learners (ELL) face great academic challenges in today’s public educational system which may be masked within the larger ELL population.
First generation Romanian children, as ELL students, are represented across the Portland metropolitan area. Although their presence is pervasive, they constitute only a small proportion of all students (2.4 percent of all students in one district). Because of the low incidence of Romanian students, and the fact they are enrolled in schools across a broad geographical area, practical barriers prohibit their participation in bilingual education programs compared to students from well-represented cultures and languages (e.g., Spanish). This project will conduct a market analysis to gauge the Portland Romanian community’s interest in opening a bilingual two-way immersion (TWI) public charter school, embracing both the Romanian culture and language. By documenting this interest, a clear direction and structure for such a school will be established, which should foster the academic success for children of Romanian heritage.

Cette etude contrastive, et les implications didactiques, du twi et du francais introduit une approche bidirectionnelle contrairement a la traditionnelle approche unidirectionnelle dans l'apprentissage des langues secondes. Dans l'approche traditionnelle l'une des langues est consideree comme la langue source et l'autre comme la langue cible dans l'enseignement des langues etrangeres. Des renseignements pedagogiques ressortent de la presentation, juxtaposition et la comparaison des systemes phonologiques des 2 langues. Ainsi dans l'enseignement du francais langue etrangere des propositions sont faites pour l'acquisition des sons du francais par le locuteur du twi, et dans l'enseignement du twi pour l'acquisition des sons du twi par le locuteur du francais. A travers les analyses statistiques, segmentales, suprasegmentales ainsi que des lois des universaux phonologiques, cette etude met en evidence aussi bien des divergences que des convergences entre sons, distributions syllabiques et structures syllabiques en twi et en francais. Dans les propositions pedagogiques l'etude fait ressortir l'inventaire et tient compte des domaines de difficultes rencontrees par l'apprenant et les systemes de facilitation de transfert lors de son apprentissage des sons du twi et des sons du francais. Muni de cet inventaire, l'enseignant-correcteur averti sera en mesure d'orienter, cibler sa methode et porter son attention sur les domaines impliques afin d'apporter des solutions aux problemes detectes et eviter les erreurs prevues dans l'acquisition des sons du twi et l'acquisition des sons du ffrancaisThe present study of the pedagogical implications of a contrastive phonology of akan (twi) and french adopts a bi-directional approach to second language learning. This is contrary to the traditional approach whereby only one of the languages compared plays the role of the source language and the other that of the target language. Through the presentation, juxtaposition and comparison of the phon ological systems of twi and french, pedagogical inferences are drawn. In the teaching of french as a second language pedagogical propositions are made towards the acquisition of french sounds by the twi speaker, and in the teaching of twi, the acquisition of twi sounds by the french speaker. Using statistical, segmental, suprasegmental analyses and other phonological rules, the study focuses on sounds, syllabic structures and distributions with and without correspondents in twi and french. The pedagogical propositions of the study focuses on an inventory of difficult areas and facilitation transfer systems in the learning of twi and french sounds. Armed with this inventory the well-informed teacher-corrector will be in a position to direct his attention to and focus his teaching methods on the areas concerned in order to find solutions to the detected problems and avoid predicted errors in the acquisition of twi sounds and in the acquisition of french sounds

Full textAbstract:
På grund av ökad urbanisering och exploatering av grönområden i stadsnära miljöer fragmenteras och reduceras arters habitat vilket bland annat ligger till grund för den globalt minskade biologiska mångfalden. För att stärka och förbättra arters möjlighet till spridning i landskapet, och därmed säkra en hög biologisk mångfald, efterfrågas insamling av data och utveckling av nya metoder för att identifiera ekologiska kärnområden och för att analysera habitatnätverk. Syftet med den här studien är därför att 1) kartera och sammanställa biotoper i en biotopdatabas utifrån tolkning av infraröda flygbilder med digital stereofotogrammetri, 2) undersöka olika metoder att samla in data med hjälp av laser- och höjddata, och 3) att tillämpa landskapsekologisk analys på underlag i biotopkarteringen. Resultatet validerar att tolkning av infraröda flygbilder med digital stereofotogrammetri är en utmärkt källa för att kartera biotoper som medför en tolkningsnoggrannhet på 86 %. Valideringen av kateringen genomfördes med fältkontroller som utvärderades i felmatriser. En metod har även undersökts baserat på tidigare studier för att uppskatta busk- och krontäckning med hjälp av laserdata, men eftersom det saknas validering av resultatet bör den användas som en indikator för att visuellt uppskatta busk- och krontäckning i dagsläget. Fortsättningsvis har ett topografiskt fuktighetsindex (TWI) tillämpats med hjälp av höjddata för att uppskatta fuktighet i vegetationstäckta områden. Eftersom det saknas validering och tröskelvärden för att avgöra hur TWI ska klassificera olika fuktighetsgradienter, bör verktyget endast användas som en indikator för att visuellt uppskatta fuktighet tillsammans med tolkning av infraröda flygbilder. Om metoderna valideras med fältmätningar kan de bidra med att förbättra kvaliteten och tidseffektivisera kartering av biotoper. Biotopkarteringen fungerar som ett bra underlag vid tillämpning av landskapsekologisk analys. Med hjälp av MatrixGreen var det möjligt att modellera potentiella habitatnätverk för två olika arter inom studieområdet. På grund av en del problem med modelleringen i MatrixGreen bör resultaten beaktas med ett kritiskt angreppssätt, men kan eventuellt användas som ett underlag för framtida artinventeringar.Due to urbanisation and exploitation of green areas in cities during the last decades, the rate of habitat fragmentation has increased, resulting in a decline in the global biodiversity. In order to strengthen the possibilities of species migration, and to secure a high biodiversity, there is an increasing demand in the collection of data and in the exploration of methods to identify ecological core areas and to analyse habitat networks at a landscape level. Therefore, this study aims to 1) map and organise biotopes in a biotope database using interpretation of colour infrared aerial photos in digital stereophotogrammetry, 2) to explore different methods using laser and elevation data in order to improve the collection of ecologically important attributes, and 3) to apply landscape ecological analysis on the collected biotope data. The results validate interpretation of colour infrared aerial photos with digital stereophotogrammetry as a key source in mapping biotopes with an overall accuracy of 86 %. A method to estimate bush and crown cover has been explored based on previous studies using laser data. It has however not been validated in this study and should therefore be used as an indicator and as support for visual estimation of bush and crown coverage using CIR aerial photo interpretation. Furthermore, a topographic wetness index (TWI) was applied using elevation data in order to estimate moisture regimes in vegetated areas. It should also be used as an indicator due to lack of verification and limitations of arranging TWI values in relation to different moisture regimes. However, if these two methods are validated using field collected data for example, they hold significant potential in improving mapping accuracies and mapping rates of different biotopes. Collected biotope data are well suited in the application of landscape ecological analysis. Using MatrixGreen, it was possible to analyse potential habitat networks of two different species within the study area. Due to some problems in the least cost path modeling in MatrixGreen, the results should be carefully assessed, but could probably be used as a background material for future species inventories.

Full textAbstract:
Through-the-wall Imaging (TWI) is crucial for various applications such as law enforcement, rescue missions and defense. TWI methods aim to provide detailed information of spaces that cannot be seen directly. Current state-of-the-art TWI systems utilise ultra-wideband (UWB) signals to simultaneously achieve wall penetration and high resolution. These TWI systems transmit signals and mathematically back-project the reflected signals received to image the scenario of interest. However, these systems are diffraction-limited and encounter problems due to multipath signals in the presence of multiple scatterers. Time reversal (TR) methods have become popular for remote sensing because they can take advantage of multipath signals to achieve superresolution (resolution that beats the diffraction limit). The Decomposition Of the Time-Reversal Operator (DORT in its French acronym) and MUltiple SIgnal Classification (MUSIC) methods are both TR techniques which involve taking the Singular Value Decomposition (SVD) of the Multistatic Data Matrix (MDM) which contains the signals received from the target(s) to be located. The DORT and MUSIC imaging methods have generated a lot of interests due to their robustness and ability to locate multiple targets. However these TR-based methods encounter problems when the targets are behind an obstruction, particularly when the properties of the obstruction is unknown as is often the case in TWI applications. This dissertation introduces a novel total sub-MDM algorithm that uses the highly acclaimed MUSIC method to image targets hidden behind an obstruction and achieve superresolution. The algorithm utilises spatio-temporal windows to divide the full-MDM into sub-MDMs. The summation of all images obtained from each sub-MDM give a clearer image of a scenario than we can obtain using the full-MDM. Furthermore, we propose a total sub-differential MDM algorithm that uses the MUSIC method to obtain images of moving targets that are hiddenbehind an obstructing material.

Full textAbstract:
Hydrological modeling, like runoff modelling for flood prevention, is based on digital elevation models (DEMs). The fact that the DEMs do not represent existing road culverts can lead to considerable hydrological misinterpretations. In order to overcome this limitation, a GIS method was developed to automatically adjust the elevation model, hydrologically enforcing the DEM, so that the results of hydrological modeling accounts for flow through culverts. The hydro-enforced DEM showed to better represent the drainage network than the former DEM when compared with the river map. The topographic wetness index is the most commonly applied topographic index and a good indicator of soil moisture distribution. It has been integrated into many hydrological models and pollution risk indices as well as into the prediction of wetland distribution. Using the hydro-DEM from the previous step and the soil map in conjunction with the TWI, an improved TWI was achieved, namely a soil-topographic wetness index (STI). The linkages between specific soil types and TWI or STI values were analyzed. They revealed a clear linkage between STI values and soil type based on the soil transmissivity (R2=0.77). However, the TWI values showed low correlations to the soil types (R2=0.02). As a specific application, both TWI and STI were tested for the detection of wetlands. Wetlands are important ecosystems which act as buffer zones by filtering pollutants and slowing floodwater. Being able to identify their distribution is important in landscape planning and ecology. A wetland threshold value was determined for each index and their results where compared with the wetland map from the property map (assumed as ground truth) and with the potential wetland area. Finally, a visual validation was performed with the use of an aerial photography. The results showed that the STI performed slightly better than the TWI for the detection of wetlands, detecting 3% more wetlands. The impact of the soil map on the topographic wetness index was therefore determined as positive.

This Master’s thesis deals with design and construction of a wireless security and surveillance system in ZigBee wireless networks (IEEE802.15.4). The design consists of creating a star network topology with intended monitoring of home area via end device boards paired with coordinator board, which provides basic networking functionality. End device is used to send data from a temperature sensor DS1631 and magnetic reed switches to coordinator. ZigBee module ZDM-A1281-A2 made by MeshNetics company embedded on each board contains a micro controller ATMega1281 and a transceiver AT86RF230 working in a 2,4GHz frequency band. System is able to notice of any door or window move actions and too high temperature. The non-fully functional ZigBee stack, which is called an Open MAC software, based on MAC (Media Access Control ) layer and PHY (Physical) layer from MeshNetics, has been used to develop the user software. Open MAC consists of three application samples in C code. One of them was modified by the user for an application of communication between the module and sensors. The same design with module RC2204AT made by Radiocrafts company was tested as well, but it couldn’t be executed. All developed boards have been constructed and tested via Terminal PC program.

Full textAbstract:
La stesura del seguente elaborato di tesi è avvenuta simultaneamente all’inizio di un progetto Lean presso il plant produttivo, situato a Crevalcore (Bo), di Fonderie di Montorso Spa, azienda produttrice di getti in ghisa. Lo scopo del seguente elaborato è di descrivere l’implementazione di un progetto Lean in uno dei settori più antichi esistenti. Negli ultimi decenni, si è sentito molto parlare di Lean production in settori come quello dell’automotive ma, raramente, si sente parlare di lean thinking o kaizen in settori metalmeccanici. I processi produttivi tipici di una fonderia, infatti, sono difficilmente prevedibili e controllabili come può essere un processo di assemblaggio di componenti.
Trasferire, dunque, un sistema di gestione della produzione, il Toyota Production System, nato in una linea di assemblaggio, in un settore con una grande quantità di vincoli di progettazione e produzione, è una sfida, una sfida necessaria per rispondere ad una situazione di estrema variabilità della domanda, in cui il mercato richiede i prodotti in maniera rapida e puntuale.
Per rimanere, dunque, competitivi è necessario un cambiamento radicale, una rivisitazione di tutti i processi aziendali partendo dall’arrivo dell’ordine, alla spedizione dello stesso. Alla luce di ciò, nel corso della trattazione, sono state svolte analisi al fine di ridurre il Lead time di partenza da 18 a 4 settimane, ponendo molta attenzione al coinvolgimento delle persone, il vero motore del cambiamento. Le parole cardine di questo elaborato sono: standardizzazione dei processi, eliminazione dei colli di bottiglia, aumento della comunicazione tra le funzioni aziendali, prioritizzazione dei clienti e per ultimo, ma non per importanza, la valorizzazione del gemba.

Full textAbstract:
Traumatic brain injury (TBI) remains an important cause of morbidity and mortality within society. TBI may result in both focal and diffuse brain injury. Diffuse traumatic axonal injury (TAI) is an important pathological substrate of TBI, and can be associated with a range of clinical states, ranging from concussion through to death, the clinical severity being associated with a number of factors related to the injury. A retrospective study was conducted using 406 cases with TBI, from the archive of the Academic Department of Pathology (Neuropathology) University of Edinburgh, during the period from1982 and 2005. This cohort was sequential and provided a unique description of the range of pathologies associated with fatal TBI within the Edinburgh catchment area. All the data was collected on a proforma and analysed to provide a description of the incidence in the injury patterns among the Edinburgh cohort. This cohort was then used to provide cases to try and critically assess the mechanisms of axonal injury in TBI. A study was undertaken to investigate TAI in an experimental model of non-impact head injury in a gyrencephalic mammalian model (piglet model) and in human autopsy materials using immunohistochemical analysis of a range of antibodies, and to define the distribution of axonal injury with flow and neurofilament markers in TAI. A further objective was to examine the expression of β-APP as an indicator of impaired axonal transport, three neurofilament markers targeting NF-160, NF-200, and the phosphorylated form of the neurofilament heavy chain (NFH), in different anatomical regions of piglet and human brains. The double immunofluorescence labelling method was then employed to investigate the hypothesis of co-localisation between β-APP and each one of the previous neurofilament markers. The animal studies showed significant differences in NF-160 between sham and injured 3-5 days old piglet cases (6 hour survival) and between 3-5 days sham and injured, when stained with SMI-34 antibody. In 4 weeks old piglet cases (6 hour survival), immunoreactivity of β-APP was significantly higher in injured than control. No other significant differences for any of the antibodies were noted, based on age, velocity, and survival time. Human results suggested that the brainstem had a higher level of β-APP and NF-160 than the corpus callosum and internal capsule. Co-localisation of β-APP with NFs was not a consistent feature of TAI in piglet and human brains, suggesting that markers of impaired axonal transport and neurofilament accumulation are sensitive to TAI, but may highlight different populations involved in the evolution of TAI.

Full textAbstract:
Semiconductor quantum dots are promising sources for polarization-entangled photons. As an alternative to the usual cascaded biexciton-exciton emission, direct two-photon emission from the biexciton can be used. With a high-quality optical resonator tuned to half the biexciton energy, a large proportion of the photons can be steered into the two-photon emission channel. In this case the degree of polarization entanglement is inherently insensitive to the exciton fine-structure splitting. In the present work we analyze the biexciton emission with particular emphasis on the influence of coupling of the quantum-dot cavity system to its environment. Especially for a high-quality cavity, the coupling to the surrounding semiconductormaterial can open up additional phonon-assisted decay channels. Our analysis demonstrates that with the cavity tuned to half the biexciton energy, the potentially detrimental influence of the phonons on the polarization entanglement is strongly suppressed-high degrees of entanglement can still be achieved. We further discuss spectral properties and statistics of the emitted twin photons.

A la suite de la revue de littérature, elle tente donc de répondre à la problématique suivante : Quels sont les facteurs qui influencent l’impact de l’usage du Tableau Blanc Interactif (TBI) sur la performance des élèves ?Avant la mise en œuvre de la recherche expérimentale, les hypothèses de départ présumaient que dans un processus d’enseignement/apprentissage médié par le TBI, la performance scolaire des élèves est influencée par le style d’apprentissage de l’élève d’une part, et d’autre part, qu’elle est fonction du type de motivation à l’égard du TBI.En vue de confronter ces hypothèses susmentionnées à la réalité du terrain, une procédure expérimentale de type pré-test/post-test, exécutée en deux phases, consistant à une situation d’enseignement/apprentissage sans le TBI et ensuite avec le TBI, a été menée, afin de mesurer la performance scolaire des élèves.Pour recueillir les données, les outils que sont le questionnaire, un test d’identification du style d’apprentissage selon le modèle VAK (Visuel, Auditif, Kinesthésique), les entretiens individuels semi-dirigés, une échelle de motivation et des observations in situ ont été utilisés.Suite à l’analyse des résultats obtenus à partir des alternatives non paramétriques du test de Khi2 et du test t de Student pour des échantillons appariés, des différences significatives sont observées au niveau de la performance des élèves de style d’apprentissage visuel, contrairement aux élèves ayant d’autres styles d’apprentissage majeur.L’impact de l’intervention du TBI dans le processus d’enseignement-apprentissage serait également fonction du genre et de la motivation de l’élève vis-à-vis du TBI. En effet, on constate que les élèves de sexe masculin et les élèves ayant une motivation autodéterminée à l’égard de l’outil technologique ont vu leurs performances augmenter significativementThanks to digital technology, many devices have appeared in classrooms and offer the possibility of multiplying teaching aids in the teaching / learning process. The interactive whiteboard (TBI / TNI) is one of them. Thus, it seems judicious to question the factors that influence the effect of such a device on school performance, given the contradictory results of scientific studies on the subject.This doctoral research work is a mixed research, combining both quantitative and qualitative data. As a result of the literature review, she tries to answer the following question: What are the factors that influence the impact of the use of the Interactive Whiteboard (IWB) on student performance?Prior to the implementation of experimental research, initial assumptions assumed that in an interactive whiteboard-mediated teaching / learning process, students' academic performance is influenced by the student's learning style of learning. on the one hand, and on the other, that it is a function of their degree of motivation with regard to the interactive whiteboard.In order to compare these above-mentioned hypotheses with the reality on the ground, a two-phase experimental procedure consisting of a teaching / learning situation without the interactive whiteboard and then with the interactive whiteboard was conducted in order to measure student academic performance.To collect the data, the tools that are the questionnaire, a test of identification of the learning style according to the model VAK (Visual, Auditory, Kinesthetic), the semi-directed individual interviews, a scale of motivation and observations in situ have been used.Following the analysis of the results obtained from the nonparametric alternatives of the Khi2 test and Student's t test for paired samples, significant differences are observed in the performance of visual learning style students, unlike students with other major learning styles.The impact of the intervention of the whiteboard in the teaching-learning process would also depend on the student's gender and motivation towards the whiteboard. Indeed, we find that male students and students with a self-determined motivation for the technological tool have seen their performance increase significantly

Full textAbstract:
This study is undertaken in the hope that the Chinese depictions of its subjects, the layman Fu Hsi and the monk Pu-tai, may serve as a gateway to a wider perception and deeper understanding of Chinese religion. In particular, this study aims to shed light on the influence of Chinese culture and religion on Buddhist tendencies in the sixth century and on the development of Chinese Zen Buddhism in the tenth. These two personages have long been regarded in Chinese Buddhist history as pre-incarnations of Bodhisattva Maitreya, Within this context the present study provides the necessary background to the Maitreya tradition in order to establish the relevant connections between these two figures, and summarizes the Buddhist background during their lifetimes. In addition, two conspectuses of the available biographical sources on Fu Hsi and Pu-tai are also presented. After unveiling Fu Hsi's biography, an in-depth analysis of Buddhist practice in early medieval China is provided to shed light on Fu Hsi's life. Every effort has been made to analyze what is represented as Fu Hsi's thought and evaluate his supposed doctrinal contributions to the Eight Schools of Chinese Buddhism. Furthermore, an endeavour has been made to delve into the enigmas of Pu-tai's life and incidents to trace Buddhist doctrinal development. Eventually, an evaluation of the influence of these two figures on various social substrata of Chinese culture is undertaken, and a comparison of the affinities and differences between these two is drawn.

This study investigated Vietnamese nursing students' perceptions of their clinical learning environment. The study was undertaken in two phases: 1) translation and adaptation of research instrument and 2) a cross-sectional survey was followed. Despite validity issues identified, data from two valid sub-scales and structured questions provided insights into the clinical learning environment that is the environment did not operate from an adult learner philosophy or provide a student-centred environment. The results are significant for development of clinical learning environment in Vietnam and that cultural differences between populations should be carefully considered in future research.

Full textAbstract:
In response to limited research conducted on the practice of assessment for learning (AfL) in higher education and in Asian educational settings, this qualitative study, using sociocultural theories of learning and a multiple case study approach, investigates how AfL was implemented by three lecturers in one Vietnamese university. Findings revealed that the lecturers engaged with AfL principles and practices to some extent. However, despite the lecturers' significant efforts, Vietnamese sociocultural factors such as respect for harmony, hierarchy, and examination-oriented learning, impacted on their practice of AfL. This study therefore argues that AfL requires adaptation for it to be effective in the Vietnamese tertiary context.

This research investigated the effectiveness of a Self-efficacy theory-based foot care education intervention program (3STEPFUN) for Vietnamese patients with diabetes at low risk of developing foot ulceration. A quasi-experimental study was conducted to determine if the intervention improved participants' foot self-care behaviour and foot risk factors for ulceration. The results showed that the 3STEPFUN has potential to prevent minor foot problems which commonly precede diabetic foot ulcers. The research provides important contributions to the current evidence base on diabetic foot ulcer primary prevention in a field where the application of theory-based nurse-administered programs is still limited.

Full textAbstract:
This thesis examines how Northern Vietnamese women with physical disabilities experienced pregnancy, childbirth, and maternal healthcare. A critical interpretative phenomenological approach and intersectional lens were utilised to understand the complexity of their experiences. The women demanded the right to pregnancy and motherhood, however, they encountered multiple challenges associated with powerful socio-cultural beliefs that intersected with gender, disability, and motherhood identities. This nexus produced and contributed to stigma, discrimination, poverty, and inaccessible environments. The findings emphasise the need for their lived experiences to shape the development and evaluation of maternal healthcare policies, programs, training, and services that impact their lives and well-being

Full textAbstract:
Total intravenous anesthesia (TIVA) is an actual topic and a still developing research area. Technological progress makes equipment for infusion increasingly sophisticated, reliable and safe. Latest infusion systems have been developed incorporating microprocessors and algorithms based on the drug’s pharmacokinetic and pharmacodynamic parameters for the population involved.
The aim of this research project was to develop and validate a system for target-controlled infusion (TCI) for administering propofol to domestic cats.
Knowledge on behavior of propofol, administered as a continuous infusion in cats are, at present, still few and sometimes contradictory.
It is well known that cats differ substantially from other animals in the ability to form glucuronide conjugates of some xenobiotics, particularly low molecular weight phenolic derivatives. A system for propofol infusion, allowing to predict as accurately as possible, the actual behavior of the drug and the concentrations at any time-point of anesthesia, may help reducing perianesthetic risk and improve quality of anesthesia.
As no publications could be found reporting three-compartment pharmacokinetics for propofol in cats, the first part of the this work was dedicated to the development of a pharmacokinetic model, on 7 cats, premedicated with medetomidine, ketamine and methadone, anesthetized with propofol and maintained with isoflurane anesthesia, during gonadectomy.
A two-compartment and a three-compartment pharmacokinetic linear model were obtained, the latter being considered the most appropriate to describe plasma concentration-time profile, based on appearance of observed and predicted concentrations and determined by least square linear regression and applying Akaike's information criterion.
The tri-compartmental pharmacokinetic data obtained in the first part of the project were used for implementation of a TCI system prototype (TCI-1), based on the free software, Computer Control Infusion Pump (CCIP) Ver 2.0E, available online (http: / / www.cuhk.edu.hk / med / ans / softwares.htm).
We analyzed the performance of the TCI-1 system during the course of anesthesia for gonadectomy in 9 premedicated cats, and target concentrations for induction, maintenance and extubation were reported.
The mean concentration, as measured by HPLC, in venous blood, two minutes after intubation was 4.92 ± 2.43 μg ml-1 and for maintenance, 4.74 ± 2.70 μg ml-1.
The indices for system prediction error, MDPE%, MDAPE%, divergence (% / hour) and wobble, calculated as described by Varvel et al. (1992), reported as median [10 / 90 percentile], were 63.50 [31.24 / 151.93], 63.50 [32.28 / 151.93], -22.77 [- 331 / 26.57], 20.32 [9.8 / 43.10], respectively. Despite it has demonstrated to be manageable in its clinical use, the system has significantly underestimated the actual concentrations, as expected for a single bolus derived pharmacokinetic model.
The next step was to optimize the TCI-1 system, modifying the pharmacokinetic data set through computer simulations. The new system (TCI-2.0) was assessed for predictive performance, in 6 cats, calculating MDPE%, MDAPE%, divergence (%/hours) and wobble, and it was compared to the results obtained with the TCI-1 system.
Mean concentration, measured by HPLC, in venous blood of cats, two minutes after intubation was 3.23 ± 0.87 μg kg-1.
Mean maintenance target concentration, calculated as the mean of targets set introduced in the system, during anesthesia, was 6.44 ± 1.27 μg ml-1, while average concentrations measured by HPLC during the same time period , was 5.56 ± 2.46 μg ml-1. Values of MDPE%, MDAPE%, divergence and wobble, reported as median [10 / 90 percentile], were -1.85 [-35.19 / 31.08], 29.67 [16.85 / 43.93], -39.08 [-50.02 / 8.23], 18.93 [10.49 / 25.01], respectively. Prediction curves, obtained by the system TCI-2.0 were similar to actually measured plasma concentrations. The resulting values for MDPE and MDAPE fall within the range described in human and veterinary literature for the validation of TCI systems in the clinical setting (MDPE <± 20% and MDAPE <30-40%). Difference in accuracy and bias observed between the two systems, TCI-1 and TCI-2.0 were statistically significant. Timing and dose of induction, maintenance, and extubation were also compared. Differences between the two systems, for doses and timing of administration and extubation, were not found to be statistically significant.
Obtained results are, in the author’s opinion, of significant scientific relevance, as they provide:
• A three-compartment pharmacokinetic model for propofol in cats, never described previously in the literature.
• A TCI system for propofol administration in cats, validated for prediction performance and easy to use in a clinical setting.
• reference values for plasma concentrations of propofol required for intubation, maintenance of anesthesia and extubation, in cats premedicated with medetomidine, ketamine and methadone, anesthetized with target infusion of propofol.L’anestesia totalmente endovenosa (TIVA) è ancora un campo in via di sviluppo. Il progresso tecnologico rende le apparecchiature per infusione sempre più sofisticate, affidabili e sicure. I sistemi infusionali più recenti sono sviluppati incorporando in un microprocessore i parametri farmacocinetici e farmacodinamici dell’anestetico impiegato, per la popolazione in oggetto. Il fine di questo progetto di ricerca è stato quello di sviluppare e validare un sistema di infusione controllata a target (TCI) per il propofol nel gatto domestico. In questa specie, le conoscenze relative al comportamento del propofol nell’ambito dell’infusione continua sono ancora poche e spesso contraddittorie. È noto che il gatto differisca sostanzialmente dagli altri animali nell’abilità di formare coniugati glucuronidi di alcuni xenobiotici ed in particolare dei derivati fenolici a basso peso molecolare. Un metodo di infusione del propofol in TIVA, che permetta di prevedere in modo più accurato possibile l’effettivo comportamento del farmaco e la concentrazione in ogni istante, può permettere di ridurre i rischi perianestetici e di migliorare la qualità dell’anestesia. Non esistendo nella letteratura una farmacocinetica tricompartimentale del propofol nel gatto, la prima parte del lavoro è stata dedicata allo studio del modello farmacocinetico su 7 gatti sottoposti a gonadectomia, premedicati con medetomidina, ketamina e metadone, anestetizzati con propofol e mantenuti in anestesia con isofluorano. È stato possibile ottenere un modello farmacocinetico bi-compartimentale ed uno tri-compartimentale. Il modello più appropriato per rappresentare la curva di concentrazione plasmatica nel tempo è stato quello tri-compartimentale, sulla base dell’aspetto delle concentrazioni osservate e predette, della riduzione della somma dei quadrati residui e dell’applicazione del test di verifica delle informazioni di Akaike. I dati di farmacocinetica tri-compartimentale estrapolati nella prima parte del progetto sono stati utilizzati per programmare il sistema di TCI prototipo (TCI-1), basato sul software gratuito Computer Control Infusion Pump (CCIP) Ver 2.0E, disponibile in rete (http://www.cuhk.edu.hk/med/ans/softwares.htm). È stata analizzata la performance del sistema TCI-1 durante l’anestesia per interventi chirurgici di gonadectomia, su 9 gatti premedicati, e sono state studiate le concentrazioni target di induzione, mantenimento e risveglio. La concentrazione plasmatica, misurata con HPLC, nel sangue venoso, due minuti dopo l’intubazione è stata in media di 4,92 ± 2,43 μg ml-1, quella di mantenimento 4,74 ±2,70 μg ml-1. Gli indici di errore del sistema, MDPE%, MDAPE%, divergenza (%/ora) e wobble, calcolati secondo quanto descritto da Varvel et al. (1992), riportati come mediana [10 / 90 percentile], sono stati pari a 63,50 [31,24 / 151,93], 63,50 [32,28 / 151,93], -22,77 [-331 / 26,57], 20,32 [9,8 / 43,10] , rispettivamente. Il sistema, nonostante si sia rivelato maneggevole nell’utilizzo clinico, ha sensibilmente sottostimato le concentrazioni effettive, come previsto per una farmcocinetica derivata da bolo singolo. La fase successiva è stata quella di ottimizzazione del sistema TCI-1, modificando il set farmacocinetico attraverso simulazioni al computer. Il nuovo sistema (TCI-2.0) è stato sottoposto a valutazione delle performances predittive, su 6 gatti, calcolando MDPE%, MDAPE%, divergenza (%/ora) e wobble ed è stato messo a confronto, per i risultati ottenuti, con al sistema TCI-1. La concentrazione plasmatica, misurata con HPLC, nel sangue venoso dei gatti, due minuti dopo l’intubazione è stata in media di 3,23 ± 0,87 μg kg-1. La concentrazione plasmatica target media di mantenimento, calcolata come la media dei target impostati nel sistema durante l’anestesia, è stata pari a 6,44 ±1,27 μg ml-1, la media delle concentrazioni misurate con HPLC, nello stesso periodo temporale, è risultata pari a 5,56 ±2,46 μg ml-1. I valori di MDPE%, MDAPE%, divergenza e wobble, riportati come mediana [10 / 90 percentile], sono stati pari a -1,85 [-35,19 / 31,08], 29,67 [16,85 / 43,93], -39,08 [-50,02 / 8,23], 18,93 [10,49 / 25,01], rispettivamente. Le curve di predizione ottenute dal sistema TCI-2.0 sono state vicine a quelle relative ai valori di concentrazione plasmatica realmente misurati. I valori ottenuti per MDPE e MDAPE rientrano nei range descritti in medicina umana e veterinaria, per la validazione di sistemi TCI in ambito clinico (MDPE < ±20% e MDAPE < 30-40%). La differenza di accuratezza e deviazione osservata tra i due sistemi TCI-1 e TCI-2.0 è stata significativa. Sono stati confrontati anche i tempi e le dosi di induzione, mantenimento ed estubazione. Non sono risultate esserci, tra i due sistemi differenze significative per dosi e tempi di somministrazione ed estubazione. I risultati ottenuti sono, secondo il parere degli autori, di significativa rilevanza scientifica, poiché forniscono: • Un modello farmacocinetico tri-compartimentale del propofol nel gatto, non descritto prima in letteratura. • Un sistema TCI con propofol nel gatto, validato per performances di predizione , facilmente fruibile in ambito clinico. • Dei valori di riferimento per le concentrazioni plasmatiche di propofol, necessarie per l’intubazione, il mantenimento e l’estubazione in gatti premedicati con medetomidina, ketamina e metadone, anestetizzati con infusione di propofol a target.

Full textAbstract:
Tai Chi Chuan, Tai Chi (TC) in short, is a popular form of Chinese martial arts which have been practised by millions of people and provides various health benefits, such as improving balance control, strengthening leg muscles, reducing fear of falling, enhancing flexibility and many more. The American Geriatrics Society and the British Geriatrics Society have recommended TC as a suitable exercise for preventing falls of older people. However, it is not clear which TC components are the most effective for balance improvement. In addition, it is also unknown what differences in biomechanics aspects are between non-TC participants and experienced TC practitioners. This thesis aims to provide new knowledge and understanding of the kinetics and kinematics characteristics of two most frequently presented TC foot movements: push-hand and Tai Chi gait (TCG), through a comparative experimental study on the ground reaction forces (GRFs) and plantar pressure distribution on both feet induced by TC and non-TC participants. Three hypotheses were proposed for facilitating this research. The characteristics of foot/leg movements in each of the simplified 24-form TC are investigated and each form is classified into one of four types. Two most frequently presented foot movements, push-hand and TCG foot movements, were identified, which are embedded in 18 of the 24 forms. This forms a basis for further biomechanics study. Ten male TC and ten male non-TC participants attended the experiments while performing push-hand, with and without an opponent, and TCG. The GRFs in the three perpendicular directions and plantar pressure distribution were measured simultaneously through using two force platforms and an insole system. A video recording system was also used to capture the movements of selected points on the subjects. The kinematics data were used to identify the critical positions that divide the leg stance phases of TCG.The characteristics of the foot forces during the two fundamental foot movements were examined and revealed. The differences and similarities on the GRFs and plantar pressure distribution generated by the two groups of participants were assessed and identified. The similarities show that the non-TC participants are able to achieve similar characteristics of foot forces as the TC participants do. The differences show that the TC participants have better control of their body movement, generating larger GRFs during push-hand and smaller GRFs during TCG in the two horizontal directions. These reflect the TC participants’ ability developed by practising TC for several years which cannot be achieved by the non-TC participants during the tests. It is also demonstrated that push-hand generates the lowest vertical foot forces among those generated by other possible human movements, such as TCG and walking.

Full textAbstract:
This thesis investigates impacts on consumers’ variety-seeking due to fit between regulatory focus (promotion, prevention) and regulatory mode (locomotion, assessment). I analysed a field dataset of 10,547 consumers and conducted three experiments across Australia, the United Kingdom, and the United States. Findings show that regulatory focus–mode fit decreases variety-seeking due to strengthened engagement and attitude certainty. Hence, this research introduces a new kind of regulatory fit, extending previous literature examining fit based on either regulatory focus or regulatory mode in isolation. Managers can segment consumers based on their motivations or adjust advertising messages to predict and influence variety-seeking.

Full textAbstract:
This thesis examined factors influencing health professional's response to victims of domestic violence in Vietnam. As this is the first time that this type of research has been conducted in Vietnam, it was expected that the results would contribute significantly to local knowledge and should add to global perspectives. Since it is the first questionnaire about this topic to be developed in Vietnam, the psychometric property of the questionnaire was primarily established, resulting in the questionnaire being recommended to use for further study. By explaining the factors that affect the intentions to respond of health workers, this project provides key data for authorities to design intervention strategies to improve the responses of health professionals to victims of domestic violence in Vietnam.

Full textAbstract:
Rice, an important crop that feeds more than half of the world's population is very sensitive to salinity stress – a growing problem affecting crop production globally. This PhD study addressed this problem by manipulating the programmed cell death pathways in rice resulting in significant enhancement of salinity stress tolerance. The impact of this work is that farmers would be in a position to grow rice containing such a trait in environments where salinisation of the soil exists, thereby addressing food security needs.

Full textAbstract:
Pressure on children to succeed in high schools is a serious problem in Asian societies. The focus of this study in three provinces of Vietnam was to identify the thresholds at which supplementary study has positive or negative effects on mental health and academic achievement. The findings contribute evidence for parents, teachers and young people about optimal levels of supplementary study (2–3 hours per day) and the most beneficial mode (self-study versus cram classes and private tutors). The work will be used to inform policy makers about strategies to minimize harmful effects of study burden for high school students.

Phan, Thi Thanh Thao. "Towards a potential model to enhance language learner autonomy in the Vietnamese higher education context." Thesis, Queensland University of Technology, 2015. https://eprints.qut.edu.au/82470/1/Thi%20Thanh%20Thao_Phan_Thesis.pdf.
Full textAbstract:
This constructivist theory-led case study explored how the term language learner autonomy (LLA) is interpreted and the appropriate pedagogy to foster LLA in the Vietnamese higher education context. Evidence through the exploration of the government policies and the cases of three EFL classes confirms the interpretation that learner autonomy and language acquisition are mutually supported. The study has proposed project work as a potential model while demonstrating the role of the teacher and the use of target language as mediators to enhance LLA in the local context. Findings of the study contribute a theoretical and pedagogical justification for encouraging LLA in Vietnam and other similar contexts.

Full textAbstract:
This thesis utilised mixed-methods study design to understand the factors that influence the translation and implementation of central human resources in health policy at the district and commune health levels. It provided recommendations for changes to enhance governance approaches to human resources for health policy implementation at local and national levels. This thesis has also contributed to the evolution of the theory on health staff motivation and performance through the description and testing of a new model, using data from a survey on 262 health staff and 43 in-depth interviews conducted in two northern mountainous provinces of Vietnam.

Nguyen, Thi My Linh. "The influence of financial risk tolerance and risk perception on individual investment decision-making in a financial advice context." Thesis, Queensland University of Technology, 2015. https://eprints.qut.edu.au/84745/1/Thi%20My%20Linh_Nguyen_Thesis.pdf.
Full textAbstract:
The aim of this thesis is to examine how risk tolerance and risk perception, two important but often misunderstood constructs, jointly influence client investment decisions in a financial advice context. By distinguishing the roles of these two risk constructs in client decision-making, in this thesis a new direction in studying financial/investment risks is provided while practice and regulation in the financial services industry is potentially informed. Based on the literature relating to risks and individual decision-making, a theoretical framework is developed and relevant hypotheses are tested in two studies with financial adviser clients in Australia. Results reveal that financial risk tolerance influences asset allocation both directly and indirectly through risk perception. The intervening role of risk perception suggests that risk tolerance affects how clients perceive the riskiness of an investment product which influences client decision-making.

Tran, Thi Tuyet Hanh. "Environmental health risk assessment of dioxin in foods and the sustainability of public health interventions at severe dioxin hot spots in Vietnam." Thesis, Queensland University of Technology, 2015. https://eprints.qut.edu.au/84905/1/Thi%20Tuyet%20Hanh_Tran_Thesis.pdf.
Full textAbstract:
This study assessed environmental health risk from dioxin in foods and sustainability of risk reduction programs at two heavily contaminated former military sites in Vietnam. The study involved 1000 household surveys, analysis of food samples and in-depth discussions with residents and officials. The findings indicate that more than 40 years after the war, local residents still experience high exposure to dioxin if they consume local high risk foods. Public health intervention programs were rated moderately to well sustained. Internal migration, and lack of clear, official guidance and sensitivity regarding dioxin issues were the main challenges for sustainability of prevention programs.

Full textAbstract:
This thesis investigates the operations of non-government organisations (NGOs) engaging in microenterprise development programs in Bangladesh and Indonesia, to understand the nature and mechanisms of NGO accountability to the poor. Findings reveal both barriers and mechanisms contributing to success within these programs. A range of mechanisms enhance both accountability of NGOs and the poor, facilitating more effective programs and sustainable poverty alleviation.

Full textAbstract:
This action research study investigated face-to-face and wiki technology collaboration to enhance students' English writing skills in a second language (L2) class in Vietnam. The thesis is underpinned by socio-cultural theory and argues that collaborative learning using wikis led to an enhancement in L2 writing skills. The findings show that collaborating via wikis challenged traditional L2 writing pedagogy in the following ways: increased student autonomy; understanding formative feedback; and awareness of process writing, genre and audiences. This study contributes practical knowledge about affordances and constraints of collaborative writing using wikis in Vietnam and other countries where traditional pedagogies are prevalent.

Full textAbstract:
This thesis examines how Vietnamese copyright law should develop to promote innovation and development in the digital age. It focuses on the important role of limitations and exceptions to copyright in encouraging access to and reuse of copyright material. This research provide important recommendations for how the scope of copyright limitations and exceptions might be expanded by adopting fair use in order to embrace new opportunities provided by the digital economy. Furthermore, it suggests that Vietnam should extend the scope of some important provisions that provide privileges for education, libraries and people with disabilities.

Full textAbstract:
This project examined teaching of heart failure self-management to both nurses and patients in Vietnam. The main study was an evidence-based clinical trial, revealing that a short individual self-care education intervention improved patients’ knowledge and adherence to recommended self-care behaviours. The thesis also highlighted that people often struggle to understand health information. It demonstrated that the teach-back method should be a priority strategy in delivering health education to those with low health literacy.

Nguyen, Thi Chau Ngan. "Aligning English for Specific Purposes (ESP) curriculum with industry needs: Language practices for Vietnam's globalised workplaces." Thesis, Queensland University of Technology, 2017. https://eprints.qut.edu.au/110536/1/Thi%20Chau%20Ngan_Nguyen_Thesis.pdf.
Full textAbstract:
The case study reported in this thesis investigated the types of English used in workplaces at the forefront of globalisation in Vietnam, namely Customs in an international airport and an import/export company. The level of alignment was then sought between these naturally-occurring genres and the English for Specific Purposes (ESP) curricula designed for graduates. Through an understanding of the sociolinguistics of mobility, the study found that the workplaces demanded functional English with a focus on communication whereas the courses largely taught lexico-grammatical knowledge. The findings contribute to greater understanding of the need for alignment and how it can be achieved.

Full textAbstract:
Abiotic stresses such as drought, salinity, and extreme temperature are significant challenges hindering the capacity of agriculture to meet the food demands of an increasing global population. This thesis characterises an osmotin gene (TlOsm) from a naturally-tolerant plant for use in the development of stress-adapted crops. The efficacy of TlOsm to improve stress tolerance was assessed and compared with two osmotins from stress-sensitive (rice) species. The results demonstrate the potential of TlOsm to improve tolerance against cold, drought, and salinity stress and highlighted the higher efficacy of genes from naturally-tolerant species.
