Authors: Хейфец  , Kheyfets Aleksandr , Васильева  , Vasileva Vera 
Published: May 2015

The article considers the state and trends in the development
of content and methodology of teaching of engineering
graphics at universities, in particular at South Ural State University
(SUSU). It is noted that the development goes in the direction of
computerization of the course and of the expansion of the scope
of application of 3D modeling and drawing.
The author overviews the content and methodology of teaching
construction engineering students of SUSU computer graphics.
The course is designed for the AutoCAD package. The article introduces
three graphical tasks that reveal features of construction
drawing. The topics of the abovementioned tasks are the perspective
and shadows, drawing of civil buildings, and drawing of truss
nodes. The course focuses on modern design technologies in construction.
To perform the aforementioned tasks the author implements
both traditional 2D (computer) methods of drawing and
modern 3D design methods which are actively developing. Work
goals and objectives for each task are given, as well as the examples
of drawings, 3D models and the sequence of their construction.
The author shows methods of studying properties of geometrical
projections and of shadowing difficult elements of building on
the example of 3D modeling. The article gives the examples of
photorealistic rendering done by the students for building visual
images.
The article also exposes shadowing in the orthographic projections
on the example of smaller architectural projects and civil
constructions. Shadows are built both in the automatic 3D modelling
and visualization mode and in traditional 2D methods.
The author dwells on modern means of automation of geometric
construction as well as shows the example of parameterization
in the process of determining optimal parameters of perspective
projections. The article reveals the construction of the dynamic
block as a means of storing graphical information of modern CAD
systems. The example of block construction in the process of truss
node creation is also given.
The author provides the requirements for the contents of the
semester report, the list of additional competencies acquired by the
student after the development of the course.

Published: May 2015

We compared the length of hospitalisation, rate of infection, dislocation of the hip and revision, and mortality following primary hip and knee arthroplasty for osteoarthritis in patients with Alzheimer’s disease (n = 1064) and a matched control group (n = 3192). The data were collected from nationwide Finnish health registers. Patients with Alzheimer’s disease had a longer peri-operative hospitalisation (median 13 days vs eight days, p < 0.001) and an increased risk for hip revision with a hazard ratio (HR) of 1.76 (95% confidence interval (CI) 1.03 to 3.00). Dislocation was the leading indication for revision. There was no difference in the rates of infection, dislocation of the hip, knee revision and short-term mortality. In long-term follow-up, patients with Alzheimer’s disease had a higher mortality (HR 1.43; 95% CI 1.22 to 1.70), and only one third survived ten years post-operatively. Increased age and comorbidity were associated with longer peri-operative hospitalisation in patients with Alzheimer’s disease.Cite this article: Bone Joint J 2015;97-B:654–61.

Published: May 2015

There is no single standardised method of measuring the orientation of the acetabular component on plain radiographs after total hip arthroplasty. We assessed the reliability and accuracy of three methods of assessing anteversion of the acetabular component for 551 THAs using the PolyWare software and the methods of Liaw et al, and of Woo and Morrey. All measurements of the three methods had excellent intra- and inter-observer reliability. The values of the PolyWare software, which determines version of the acetabular component by edge detection were regarded as the reference standard. Although the PolyWare software and the method of Liaw et al were similarly precise, the method of Woo and Morrey was significantly less accurate (p < 0.001). The method of Liaw et al seemed to be more accurate than that of Woo and Morrey when compared with the measurements using the PolyWare software. If the qualified lateral radiograph was selected, anteversion measured using the method of Woo and Morrey was considered to be relatively reliable. Cite this article: Bone Joint J 2015; 97-B:611–16.
Initial Usability and Feasibility Evaluation of a Personal Health Record-Based
Self-Management System for Older Adults
Authors: Sheehan Barbara , Lucero Robert James 
Published: May 2015

Introduction: Electronic personal health record-based (ePHR-based) self-management
systems can improve patient engagement and have an impact on health outcomes. In order
to realize the benefits of these systems, there is a need to develop and evaluate heath
information technology from the same theoretical underpinnings.Methods: Using an
innovative usability approach based in human-centered distributed information design
(HCDID), we tested an ePHR-based falls-prevention self-management system—Self-Assessment
via a Personal Health Record (i.e., SAPHeR)—designed using HCDID principles in a
laboratory. And we later evaluated SAPHeR’s use by community-dwelling older adults at
home.Results: The innovative approach used in this study supported the analysis of four
components: tasks, users, representations, and functions. Tasks were easily learned and
features such as text-associated images facilitated task completion. Task performance
times were slow, however user satisfaction was high. Nearly seven out of every ten
features desired by design participants were evaluated in our usability testing of the
SAPHeR system. The in vivo evaluation suggests that older adults could improve their
confidence in performing indoor and outdoor activities after using the SAPHeR
system.Discussion/Conclusion: We have applied an innovative consumer-usability
evaluation. Our approach addresses the limitations of other usability testing methods
that do not utilize consistent theoretically based methods for designing and testing
technology. We have successfully demonstrated the utility of testing consumer technology
use across multiple components (i.e., task, user, representational, functional) to
evaluate the usefulness, usability, and satisfaction of an ePHR-based self-management
system.
Transitioning from secondary school to art college – are guidelines for entrance portfolios an institutional barrier to visual arts higher education in Ireland?
Authors: Maguire Dee 
Published: May 2015

Abstract
This article draws on recent research that explored the role of extra-curricular portfolio preparation tuition in the context of Irish visual arts education. This mixed methods study comprised three distinct but interrelated components including a conventional content analysis of published portfolio guidelines for all 2013 entry to degree programmes in visual art institutions in the State. This article presents the results of this analysis, identifying Technical Ability, Desired Personal Attributes and Critical Enquiry as the three main criteria for success. It is further suggested that due to a lack of clarity and to ambiguities in design, portfolio guidelines are often hard for second level students to decipher unaided. This creates an Institutional Barrier to participation to visual arts higher education when combined with the differing objectives of the State Leaving Certificate examination in art; resulting in a requirement for extra-curricular portfolio preparation tuition.
Genetic Variability Under the Seedbank Coalescent
Authors: Blath Jochen , González Casanova Adrián , Eldon Bjarki , Kurt Noemi , Wilke-Berenguer Maite 
Published: May 2015

Abstract
We analyze patterns of genetic variability of populations in the presence of a large seedbank with the help of a new coalescent structure called the seedbank coalescent. This ancestral process appears naturally as a scaling limit of the genealogy of large populations that sustain seedbanks, if the seedbank size and individual dormancy times are of the same order as those of the active population. Mutations appear as Poisson processes on the active lineages and potentially at reduced rate also on the dormant lineages. The presence of “dormant” lineages leads to qualitatively altered times to the most recent common ancestor and nonclassical patterns of genetic diversity. To illustrate this we provide a Wright–Fisher model with a seedbank component and mutation, motivated from recent models of microbial dormancy, whose genealogy can be described by the seedbank coalescent. Based on our coalescent model, we derive recursions for the expectation and variance of the time to most recent common ancestor, number of segregating sites, pairwise differences, and singletons. Estimates (obtained by simulations) of the distributions of commonly employed distance statistics, in the presence and absence of a seedbank, are compared. The effect of a seedbank on the expected site-frequency spectrum is also investigated using simulations. Our results indicate that the presence of a large seedbank considerably alters the distribution of some distance statistics, as well as the site-frequency spectrum. Thus, one should be able to detect from genetic data the presence of a large seedbank in natural populations.

Published: May 2015

ABSTRACTThis work investigates the effects of concentration of organothiol molecules and temperature used during self-assembled monolayers (SAMs) formation on quality of the organothiol SAMs coating layer obtained in terms of wettability, corrosion inhibition efficiency and carbon to copper ratio. The organothiol SAMs were coated on copper substrates prepared by electro-polishing followed by oxygen plasma treatment for 15 s. Three types of organothiol SAMs including 1-octanethiol (OTT), 2-ethylhexanethiol (2-EHT) and 2-phenylethanethiol (2-PET) were investigated. Concentration of organothiol molecules ranging from 0.005 to 0.02 M in isopropanol and forming temperature ranging from -15 to 50°C were studied. It was found that all organothiol SAMs of 0.01 M provided the SAMs coating layer with the highest quality. The SAMs formed at 40°C with OTT and 2-EHT, and at 0°C with 2-PET were the most favorable condition with the highest water contact angle of 124.79o, 130.66o and 120.58o at corrosion inhibition efficiencies of 96.24%, 99.37% and 98.90%, respectively.
Improving Labor Neuraxial Analgesia by Reducing Anesthesia Provider Practice Variance Involving Routine Platelet Counts: A Quantitative Quality Improvement Project
Authors: Johnson Paul M. , Walter Thomas R. , Fugate Stephanie R. , Titch James F. 
Published: May 2015

For this quality improvement (QI) project, the desired outcomes were the reduction of the incidences of withheld neuraxial analgesia (NA) for healthy parturients and the adoption of evidence-based practice (EBP) by the anesthesia providers (APs). The practice change was designed using the diffusion of innovations in health service organizations change model. The 3 interventions used to achieve the outcomes of the project were (a) revision of the anesthesia service’s standard operating procedure (SOP) to incorporate recent recommendations addressing platelet count limits for parturients, (b) addition of a clinical decision reminder in the patient’s electronic medical record (EMR), and (c) educating obstetrical APs about the new SOP and updated EMR.Outcomes were measured using pre- and postimplementation surveys of the staff who work on the labor and delivery ward to evaluate AP practice variance and a modified EBP Implementation Scale to measure the adoption of the evidence by the APs. The QI project was successful in reducing practice variance and resulted in fewer incidences of withheld NA for healthy parturients, and 57.1% of the APs reported changing their practice by adopting the evidence for this project.
Effectiveness of Chlorophyll Meter Measurement in Winter Wheat at Field Scale Level

Published: May 2015

Abstract
This paper examines the relationship among chlorophyll meter Yara N-Tester readings, nutrition status and growth parameters (leaf area index (LAI), plant height) of the winter wheat plants. Data used in this study were collected in 2010 from two fields located in the Czech Republic (area 52 and 38 ha) from different farms, both with uniform and conventional crop management. The monitoring of crop stands was done at growth stage BBCH 30 in a regular sampling grid with 150 m distance between points (27 and 18 points). At each sampling point, the plant height, LAI (Delta-T SunScan) and the chlorophyll concentration (Yara N-Tester) were recorded. Plant samples were taken to analyse the content of main nutrients (N, P, K, Mg, Ca and S). The results of plant analysis showed that both fields were in different nutrition status: one in a correct status and another had a complex nutritional deficit (K, Ca and N). Linear regressions and ANOVA proved that under a multiple nutritional deficit, N-Tester readings responded to the growth of the crop, while in the adequate nutritional conditions the sensitivity of N-Tester to the variation in the nitrogen concentration is lower. The relationships between crop parameters and chlorophyll meter readings are not generalisable and thus the interpretation of N-Tester results has to be done separately for each field.
