Authors: Cole Christopher J. , Russell Kirk S. , Han Jasmine J. 
Published: December 2017

Background:
Imaging plays a major role in the detection, diagnosis, and ultimate treatment
strategies of adnexal masses. As high as 10% of women in the United States undergo surgical
evaluation for a suspected adnexal neoplasm.

Objective:
To understand the advantages and disadvantages of each imaging modality used in the
evaluation of adnexal masses.

Results:
Ultrasound is frequently the imaging modality of choice for initial characterization.
Computed tomography, magnetic resonance imaging, and positron emission tomography – computed
tomography are frequently employed if malignancy is suspected to assess for metastasis.

Conclusion:
A basic understanding of adnexal imaging modalities will be of benefit to care providers
and, in turn, be of benefit to patients.
Automatic Anisotropic Diffusion Filtering and Graph-search Segmentation of Macular Spectral-domain Optical Coherence Tomographic (SD-OCT) Images
Authors: Usha A. , Shajil Nijisha , Sasikala M. 
Published: December 2017

Background:
Optical Coherence Tomography (OCT) is a non-invasive medical imaging
technique that provides high-resolution cross-sectional images of the retina. There is a need to develop
algorithms for obtaining quantitative and qualitative information about the retina which are
essential for assessing and managing eye conditions.

Methods:
This work emphasizes on an automated image processing algorithm for segmenting retinal
layers. It involves preprocessing of the acquired retinal SD-OCT image (B-scan) using the proposed
automatic Anisotropic diffusion filter, followed with contrast stretching to suppress intrinsic
speckle noise without blurring structural edges. Graph search segmentation using Dijkstra algorithm
with a combination of threshold and axial gradient as the cost function is used to segment the
retinal layer boundaries.

Results:
The algorithm was performed and the average thickness of the segmented retina was computed
for the 3D retinal scan (128 B-scans) of 8 subjects (4 normal and 4 abnormal) using Early
Treatment Diabetic Retinopathy Screening (ETDRS) chart.

Conclusion:
Segmentation was evaluated using manually segmented B-scan by an Ophthalmologist
as ground truth and accuracy was found to be 99.14 ± 0.27%.
Preparation of Nano-Co3O4 by Direct Thermal Decomposition of Cobalt(II) Nitrate Hexahydrate for Electrochemical Water Oxidation
Authors: Ahmed Qasem Mohammed Ameen , Aziz Md. Abdul , Hakeem Abbas Saeed , Onaizi Sagheer A. 
Published: December 2017

Background:
Nano-Co3O4 has been used in various technological areas and applications
such as electrochemical sensors and electrochemical water splitting. Even though many efforts have
been expended to prepare nano-Co3O4, the development of novel methods to prepare Co3O4 using
simple processes and at low cost remain a topic of interest. Besides, it could be economic and useful
if the synthesized nanoparticle could be applied as efficient electrocatalyst upon its immobilization
on a cheap base electrode material by very simple method for various practical applications including
renewable energy.

Method:
We prepared nano-Co3O4 by a direct thermal decomposition of an inexpensive, simple and
widely available cobalt inorganic precursor, such as Co(NO3)2·6H2O without any type of prereaction
or processing. The nano-Co3O4 was immobilized on filter-paper-derived carbon electrode by
drop-drying method for applying as electrode materials toward water electrooxidation.

Results:
The X-ray diffraction, field emission scanning electron microscopy, and transmission electron
microscopy analysis confirmed the formation of short nanorods of single-phase Co3O4 upon
thermal decomposition of Co(NO3)2·6H2O at 520°C. The electrocatalytic properties of the nano-
Co3O4 were evaluated after immobilizing it on a cheap carbon electrode derived from normal filter
paper. The modified electrode showed good electrocatalytic properties toward water oxidation in an
alkaline solution.

Conclusion:
In conclusion, we developed a very simple, straight-forward and economic method for
preparation of nano-Co3O4 and immobilized it on very cheap carbon electrode for evaluating its electrocatalytic
properties. Due to the high electrocatalytic properties, the prepared nano-Co3O4 could
potentially play an important role in various practical fields.

Authors: Antiabong John F. , Kock Marleen M. , Maphanga Tsidiso G. , Salawu Adeola M. , Mbelle Nontombi M. , Ehlers Marthie M. 
Published: December 2017

Background:This study sought to understand the epidemio-ecological dynamics of MRSA isolates associated with a South African hospital over a period spanning year 2007-8 (a previous study reported in 2009) and year 2010-11 (this study).Methods:One hundred and ninety three isolates were characterised by molecular fingerprinting methods including pulsed field gel electrophoresis (PFGE),spatyping,agr-typing, SCCmec-typing, and multilocus sequence typing (MLST). The Vitek-2 automated antibiogram of representative isolates was also performed.Results:Our data shows that the distribution of MRSA strains among the different clinical conditions was rarely dependent on the genetic backbone or genotype. Compared to the previous survey in 2009, CA-MRSA isolates increased by 31% while HA-MRSA isolates decreased by 17%. An increase in genetic diversity was also revealed including the detection of three pandemic clonal complexes (spatype t012-ST36/CC30,spatype t037-ST239/CC8,spatype t891-ST22/CC22 andspatype t1257-ST612/CC8). Majority of the genotypes were classified as Spa Cluster B-SCCmecI-agrI 19.2%; (37/193) Spa Cluster A-SCCmercury-agrI 14.5%; (28/193)Conclusion:This study reveals that increased diversity in MRSA genetic background was associated with resistance to frontline antibiotics. Also, an increase was recorded in the CA-MRSA/HA-MRSA ratio within a 5-year period despite the continuous dominance of the HA-MRSA genotype.
A Systematic Review and Comprehensive Critical Analysis Examining the Use of Prednisolone for the Treatment of Mild to Moderate Croup
Authors: Elliott Anna Catherine , Williamson Graham R. 
Published: December 2017

Background:Many randomised control trials and systematic reviews have examined the benefits of glucocorticoids for the treatment of croup in children, but they have reported mainly on dexamethasone as an oral treatment for croup. No systematic reviews have examined prednisolone alone.Aim:To determine in a systematic review of the literature whether a single dose of oral prednisolone is as effective as a single dose of dexamethasone for reducing croup symptoms in children.Search Strategy:A detailed search was conducted on the following databases: CINAHL, MEDLINE EBSCO, MEDLINE, OVID, PubMed, The Cochrane Library, ProQuest, EMBASE, JBI, Sum search, and OpenGrey. Study authors were contacted.Selection Criteria:Randomised Controlled Trials, clinical trials or chart reviews which examined children with croup who were treated with prednisolone alone, or when prednisolone was compared to a dexamethasone treatment and the effectiveness of the intervention was objectively measured using croup scores and re-attendance as primary outcomes.Data Collection and Analysis:Following PRISMA guidelines for systematic reviews, relevant studies were identified. Scores were graded agreed by two independent reviewers using QualSyst.Main Results:Four studies met the inclusion criteria, but were too heterogeneous to combine in statistical meta-analysis. The result suggests that although prednisolone appears as effective as dexamethasone when first given, it is less so for preventing re-presentation. Trial sample sizes were small, making firm conclusions difficult, however, a second dose of prednisolone the following day may be useful. More research including cost-benefit analysis is needed to examine the efficacy of prednisolone compared to dexamethasone.
Survival and growth of nursery inoculated Fraxinus uhdei in acrisol gullies
Authors: Báez-Pérez Ana Laura , Lindig-Cisneros Roberto , Villegas Javier 
Published: December 2017

Presence of degraded soils is increasing worldwide, but in many scenarios the knowledge to undertake restoration has not been acquired in an efficient, economical and socially acceptable manner. There are estimates placing moderate to severe degradation of agricultural land worldwide at 80%. Severely degraded substrates, such as gullies, sometimes lack the necessary microbiota for appropriate plant growth, under these conditions nursery inoculation can improve plant performance in the field. In order to explore the role of dual mycorrhization in Fraxinus growing in poor substrates, and also to contribute information on their usefulness in gully restoration, an experiment was conducted in which individuals of this species were inoculated with an endomycorrhyzal fungus, and ectomycorrhizal fungus and with both types of mycorrhizal fungi simultaneously, as well as urea fertilization. The results of this experiment show that establishment of Fraxinus uhdei is possible in severely degraded sites, it also provides information on the effects on the plant of multiple inoculation that cause some performance variables to improve as a result of the interaction, as was the case for the improved survival with the P. tinctorius, G. intraradices dual inoculation; whereas growth variables showed improved response to inoculation with only one of the fungi, height to inoculation with G. intraradices, and cover, number of leaves and diameter at base to inoculation with P. tinctorius. Given the improvements in growth and survival, our results suggest that in severely degraded soils, nursery inoculation of plants adapted to adverse conditions with mycorrhyzal fungi should be implemented.
THE STORY OF THE BC FAMILY JUSTICE INNOVATION LAB
Authors: Morley Jane , Boyle Kari D 
Published: December 2017

Many in the justice system know that fundamental change is needed but few know the best way to do it. Previous attempts using strategic planning approaches have not achieved meaningful change. Something different is needed. The BC Family Justice Innovation Lab (the Lab) is experimenting with a different approach drawing on complexity science, the experience of other jurisdictions and disciplines and incorporating human-centred design as a way of focusing on the well-being of families going through the transition of separation and divorce. This article is the story of the first few years of the Lab’s life. It has been a fascinating and challenging path so far, and it remains to be seen whether it will ultimately succeed. The story is offered so that others with similar ambitions can learn from the Lab’s experience – its successes and its failures. It is the nature and strength of stories that the reader will take from them what they will. For the authors, one overriding theme that emerges from this story is that transforming a complex social system, such as the family justice system in British Columbia, requires embracing the complexity of paradox and refusing to be defeated by the tension of opposites and a multitude of wicked, unanswerable questions.

Diabetes melitus (DM) is defined as a chronic metabolic disease or disorder with multiple etiologies characterized by high blood sugar levels. One way to treat diabetes mellitus is inhibiting the α-glucosidase enzyme. This study aims to determine the inhibition of α-glucosidase of methanol extract of kiwi fruit (Actinidia deliciosa) . Kiwi fruit (Actinidia deliciosa) contains saponins characterized by the formation of foam, positive flavonoid characterized by the formation of a yellow color (orange) and positive alkaloid which is characterized by brown color in wagner test. The inhibition activity test of α-glucosidase enzyme was performed by using spectrophotometric method. The results of the inhibition activity test of α-glucosidase enzyme in acarbose showed the value of 13,672 mg/L, while the methanol extract of kiwi fruit showed IC50 value of 7.219 mg/L. It demonstrated that themethanol extract of kiwi fruit has the inhibition activity greater than acarbose.
Fair Value Accounting and Earnings Persistence: Evidence from International Banks
Authors: Yao Daifei (Troy) , Percy Majella , Stewart Jenny , Hu Fang 
Published: December 2017

ABSTRACT
Using hand-collected data from a sample of 210 international banks during the period 2009 to 2013, we investigate whether fair value exposure, the proportion of financial assets measured at fair values, is associated with earnings persistence and whether the reliability of fair value measurements influences earnings persistence. We also examine whether the association between fair value measurements and earnings persistence is a function of institutional factors such as legal enforcement, the audit environment, and country-level auditor industry expertise. Results suggest that the use of fair values for balance sheet financial instruments enhances earnings persistence. Also, we find that the nondiscretionary fair value Level 1 assets (measured with observable inputs) are positively associated with earnings persistence, whereas the Level 2 assets (measured with indirectly observable inputs) and Level 3 assets (measured using unobservable inputs) are not associated with earnings persistence. We provide further evidence that there is a strong association between factors reflecting countrywide institutional structures and the predictive power of fair values based on discretionary measurement inputs (Level 2 and Level 3 assets) and we find that the moderating effect from these institutional factors is greater for Level 3 assets than for Level 2 assets. Additional tests suggest that the association between fair value estimates and earnings persistence is moderated by the classification of fair value assets (that is, through profit and loss versus other comprehensive income) and the reliability of fair value estimates.
Marcuse e o Biopoder: como a liberdade sexual transforma-se em um instrumento de controle social
Authors: Barbosa Alexandre De Moura 
Published: December 2017

Proponho mostrar uma interpretação de “Homem unidimensional” acerca da liberdade dos corpos na sociedade industrial. Se outrora houve uma grande promessa da técnica de promover a liberdade pela Razão, o que ocorreu foi um paradoxo nessa sociedade industrial como sujeita a uma irracionalidade na dependência das necessidades e carências o que, por fim, constituem os indivíduos imersos nessa unidimensionalidade. Nessa imersão há um "controle social" caracterizado pela utilização das necessidades como instrumentos de cooptação na produção e no consumo no interior da sociedade industrial. A liberdade sexual ou dos corpos está submetida a esta forma de cooptação ideológica por parte das necessidade e consumos no interior dessa sociedade. O que podemos ver é que há uma forma de “biopoder” nesse “controle” que vai para além da mera sociedade repressiva, trata-se de uma transformação de substituições e sublimações de desejos e das forças libidinais em novas formas de necessidades e consumos que submetem a liberdade e, particularmente, a liberdade sexual e dos corpos ao controle social.

Penerapan Augmented Reality Sebagai Media Pembelajaran Sistem Pencernaan pada Manusia dalam Mata Pelajaran Biologi
Authors: Mauludin Rizqi , Sukamto Anggi Srimurdianti , Muhardi Hafiz 
Published: December 2017

Perkembangan teknologi informasi di bidang pendidikan, salah satunya adalah teknologi Augmented Reality (AR) yang dapat dimanfaatkan sebagai media pembelajaran multimedia termasuk media pembelajaran sistem pencernaan manusia. Hal ini dikarenakan proses pembelajaran tentang sistem pencernaan manusia masih melalui media-media konvensional seperti papan tulis dan gambar - gambar yang terdapat di buku biologi. Sementara materi tentang sistem pencernaan manusia sangat sulit untuk dilihat langsung secara langsung karena sebagian besar berada didalam tubuh. Kelebihan dari Augmented Reality adalah tampilan visual yang menarik, karena dapat menampilkan objek 3D beserta animasinya yang seakan-akan ada pada lingkungan nyata dan disandingkan dengan informasi tentang objek 3D yang berupa suara, diharapkan dapat digunakan sebagai alternatif media pembelajaran untuk mengenalkan sistem pencernaan pada manusia yang mampu membuat pengguna tertarik mempelajarinya. Pada penelitian ini digunakan Game Engine UNITY untuk membangun aplikasi berbasis Android serta Vuforia SDK agar aplikasi yang dibangun dapat menjadi aplikasi berteknologi Augmented Reality. Disertai dengan 1 gambar marker yang terdapat didalam buku pelajaran biologi yang apabila diarahkan ke aplikasi dapat menampilkan visualisasi objek 3D seperti gigi anak, gigi dewasa, gigi geraham, lidah, animasi pencernaan mulut, kerongkongan, lambung, usus halus dan usus besar. Aplikasi ini dapat bermanfaat bagi siswa sekolah menengah atas (SMA), yang memperoleh materi pembelajaran sistem pencernaan manusia. Berdasarkan pengujian kompabilitas, aplikasi ini sudah berjalan dengan baik pada perangkat mobile Android, mulai dari Android versi 4.2.0 (Jelly Beans) hingga Android versi 7.0 (Nougat). Dari hasil pengujian Pre Test dan Post Test yang telah dilakukan, untuk kelompok siswa yang belajar menggunakan buku biologi memiliki persentase kenaikan dari nilai Pre Test ke Post Test sebesar 14,5 %, sedangkan untuk kelompok siswa yang belajar menggunakan aplikasi Augmented Reality Sistem Pencernaan memiliki persentase kenaikan dari nilai Pre Test ke Post Test sebesar 24,8 %, yang berarti Augmented Reality dapat diterapkan sebagai media pembelajaran sistem pencernaan manusia.
