The challenges of using information communication technologies in the healthcare systems in Ethiopia from provider's perspectivesDejene Kebede Challa 11 1900 (has links)
The adoption of eHealth is very slow despite evidences showing its benefits. This research examines the individual, clinical, technical and organizational challenges for eHealth adoption from healthcare provider‟s perspectives. A cross-sectional study design with a quantitative paradigm was used. The study was conducted on 312 doctors and nurses randomly selected from ten hospitals in Addis Ababa, Ethiopia. Most respondents viewed eHealth positively with no significant differences in terms of profession or gender. Computer skill, workload, patient interaction, management support, cost and infrastructure were the main concerns. Privacy and security were not the main concerns. Knowledge of eHealth applications and utilization was low, even for evidence-based medicine and online databases. Specialists and males were better aware of eHealth applications. The study showed that eHealth acceptance was good. Increasing eHealth literacy was recommended as a cost effective means for improving access to updated information to improve the quality of healthcare. / Health Studies / M.A. (Public Health (Medical Informatics))

How to increase the understanding of differentials by using the Casio-calculator model 9860 G I/II to solve differential equationsBjørneng, Bjørn 12 April 2012 (has links)
The major aims of this paper are to present how we can improve the students understanding and involvement in mathematics by using a programming/graphic calculator. I will use differentials as examples such as differentiation ,integrals and differential equations, creating lines of slopes for differential equation of the type y’= f(x,y) . Find the solution of some differential equations by using regression and create the graph connected to the differential equation. As we have different approaches to solving a problem, it is a hope the students interest in mathematics will improve. The tools used will be programming, graphic commands as plot, f-line, etc. One goal is also to show how we can create small programs solving problems in mathematics. For many students this will be a stepping stone for further work with programming. The programs used can be copied using the program FA 124 that can be downloaded from Casios homepages. On request I can send you the programs.

Effects of Direct Instruction Common Core Math on Students With Learning DisabilitiesMonye, Joseph Ifeanyi 01 January 2016 (has links)
U.S. students with learning disabilities' math skills acquisition has been on the decline in recent years. Studies show that teachers using traditional methods of teaching math lack knowledge of task analysis, chunking, sequencing, mass practice, modeling, and repetition of instruction. These components of direct instruction or pedagogical activities are hallmarks of special education teaching and are collectively described as cognitive support pedagogy. The study evaluated direct instruction teaching strategies to teach Common Core math to middle school students with learning disabilities, to determine if the current downward trend in math skills acquisition amongst them can be reversed. The theoretical framework of this study was based on Watson's theory of behavioral psychology as it applied to learning and teaching. The participants consisted of a convenience sample of students with learning disabilities. The study used a Solomon 4-group experimental design, in a series of two One-way ANOVAs to measure differences in math score by intervention for pretested and for non-pretested students, with one Factorial 2 X 2 ANOVA which measured for differences by interaction between pre-testing and intervention. Results of ANOVAs were significant at the α-levels of .05 (F (1,78) = 233.66 p < .001), indicating that significant differences existed in math scores of pre-tested students who received intervention and those who did not. The study is significant to teachers, curriculum developers, and instructional leaders because it is the first study of its kind to measure the outcomes of Common Core math using direct instruction and it points a way forward to creating positive social change by increasing students' graduation rates and promoting students' engagement in school and beyond.

Grafický editor simulačních modelů / Graphical Editor of Simulation ModelsHořák, Jan January 2008 (has links)
This paper contains brief introduction into modeling and simulation using Discrete Event Specified System (DEVS) formalism. It defines basic models (atomic and coupled DEVS) and shows how they are simulated. Examples of derived DEVS formalism like parallel DEVS or DESS are also presented. It is described how to create DEVS models using graphic modeling software and advantages and disadvantages of this approach. A short summary of known programs are also covered. Storing models in the XML language, validation of XML document and transformation capabilities by XSLT are discussed. The main section is dedicated to the design of a graphic editor for simulation models inspired by design patterns including classes for canvas, model representation, export module interface and main application. The XML document used for storing DEVS models and simple DEVS simulator are also described. Implementation section presents used programming libraries, reasons why they have been used and their advantages and disadvantages. Paper ends with an example of a simple DEVS model created by implemented graphic editor for simulation DEVS models.

Optimalizace návrhu moderních nízkoenergetických dřevostaveb / Optimizing the design of modern low-energy wooden housesVahalová, Eva January 2017 (has links)
The main aim of the thesis was focused on hygrothermal simulation of critical details of two prefabricated wooden buildings - especially connections of the perimeter wall to monolithic foundations, respectively with waterproofing layer. The composition of the external walls of these selected buildings has quite different compositions and thus different potentials of drying integrated moisture from the components. Practical measurement of moisture weight-content was applied to the wooden bottom plate, which is in direct contact with the concrete slab structures. The influence of different design solutions on hygrothermal characteristics of the wooden plate was examined with regards to the risk of mould growth, analysis of mass loss due to the decay fungi and with the aim to estimate the durability of the studied details of prefabricated wooden houses. The subsequent research focused on the differences in physical and mechanical properties of natural spruce wood (Untreated, (-), A) and impregnated spruce (Treated, (+), B) using supercritical CO2 and its possible impact on wood protection for mould growth. Samples of identical Untreated and Treated spruce were collected in the laboratory and subjected to thermal and hygrothermal experiments. The comparison of the resulting values of the individual experiments is presented. Required values needed for numerical calculations were obtained from these experiments. In conclusion, the summary of founded comparison is presented. The mould growth analysis and its influence on the durability of wooden structures offer a view of the behaviour of the structures. Relevant findings and recommendations for the future praxis are mentioned.

Measurement of focal spots of X-ray tubes using a CT reconstruction approach on edge images of holes with a diameter larger than the focal spot and comparison to classical pinhole imagingHashemi, Seyedreza 18 July 2024 (has links)
Non-destructive testing (NDT) combines the application of the sciences of phys-ics, mathematics, chemistry, and biology to create a comprehensive process, that can be used for inspection, examination, and testing of materials or components to find flaws, defects or discontinuities at the surface, subsurface areas, or inner volume of the component under test. NDT maintains the serviceability of the component after inspection, without causing any damage to its original form or usefulness. In addition to the need for safety, NDT is used to ensure the efficiency and durability of the equipment. NDT is carried out to ascertain that the compo-nents or materials being used are not damaged or faulty and are fit to be used by any personnel. The result of testing can show whether the components need to be repaired or if they are safe for operation. The first NDT method to evolve in the industrial age was X-ray testing (RT). This innovation was discovered by German physicist Wilhelm Conrad Röntgen in 1895. His experiments involved cathode rays which led to not only the discovery of X-ray but to the first Nobel Prize. Among all NDT methods, RT is no exception, so there are still many issues for optimizations even today. One of them is the measurement of the focal spot of X-ray tubes. The size of the focal spot is critical for imaging because it deter-mines the spatial resolution in the X-ray image. The classical way to image focal spots of X-ray tubes is by pinhole imaging using a camera obscura. This is caused by the fact, that X-ray radiation cannot be imaged by lenses like optical wavelengths. This pinhole imaging has been standardized since a long time, e.g., by EN 12543:1999, ASTM E 1165:1992, IEC 336:1982, and DIN 6823:1962. But this method has a natural lower limit, which is defined by the diameter of the pin-hole (today min. 10 µm). Focal spot sizes lower than this diameter cannot be im-aged and measured correctly. Meanwhile, the development of algorithms of Computed Tomography allows a similar approach for focal spot imaging but using pinholes with a much larger diameter than the focal spot size to be imaged. In such a large hole the edge unsharpness of the hole rim by the focal spot size can be measured in different directions, and a first derivative following a CT recon-struction will deliver a nearly identical focal spot image compared to classical pin-hole imaging. There is principal no lower focal spot size limit anymore. Computa-tional problems must be analyzed and application and parameter range for practi-cal focal spot measurements have to be determined.
