Energy spectrum computed tomography improves the differentiation between benign and malignant solitary pulmonary nodules
Authors: Zhao Jianhong , Chai Yanjun , Zhou Junlin , Zhang Zhuoli , Wang Zhiping
Published: September 2019

Purpose: To evaluate the diagnostic efficiency of computed tomography (CT) values at the 40~140 keV monochromatic level for the differential diagnosis of solitary pulmonary nodules (SPNs).

Methods: Energy spectrum CT data of 44 patients with SPNs were analyzed retrospectively; 24 patients with malignant SPNs served as the malignant group

and 20 patients with benign SPNs served as the benign group. The basic material concentration and the enhancement degree differences in double-phase enhanced scans were compared between the two groups. The sensitivity and specificity were calculated to determine diagnosis, and were compared with the pathology results.

Results: The CT values at the 40~90 keV monochromatic level and the iodine concentrations of malignant group were higher than those of benign group in the arterial phase (all P < 0.05). The enhancement degree of the malignant group was higher than that for the benign group in the arterial phase (36.36 ± 33.18 HU vs 16.93 ± 24.17 HU t = 2.243, P = 0.030); however, the enhancement degrees of the two groups were similar in the venous phase (21.99 ± 15.87 HU vs 17.62 ± 24.15 HU t = 0.694, P = 0.493). The area under the curve of the enhancement degree in the arterial phase was 0.792.

Conclusions: Monochromatic imaging and base material concentration of energy spectrum CT can help differentiate between benign and malignant SPNs.

Published: September 2019

Purpose: To assess the association of specific newborn and maternal factors with indicators of increased blood-forming capacity in umbilical cord blood to

inform strategic collection strategies that could augment the quality of units in public cord blood banks.

Methods: Data regarding 268 consecutive cord blood units (CBUs) banked by Canadian Blood Services were analyzed. Multivariate analysis was performed to

identify factors associated with markers of hematopoietic potency and likelihood of utilization.

Results: Delayed clamping of the cord beyond 60 s was associated with reduced volume collected. Any delay in clamping of the cord was associated

with reduced total nucleated cell counts. Newborn weight >4,000 g was also associated with greater blood volume in the collection but not with other measures of hematopoietic potency. Cord blood acidosis at birth (pH
The Riddle of the Fowl and the Eagle
Authors: Benitez Christian Jil
Published: September 2019

Alvin Yapan’s “The Riddle of the Fowl and the Eagle” (Filipino: “Ang Bugtong ng Manok at Agila”) teases at the boundaries between the cultural, the natural, and the supernatural, in order to foreground a contemporary Philippine conundrum that elucidates an ethical concern. The story questions what it is to be human, and what it means to be so in times that are rather inhumane. In the context of this text, this is simultaneously a concern with the meaning and value of animality. Through its rhythm, the text demonstrates a contemporary tropical consciousness that simultaneously navigates the individual and the collective so as to confront ecocritical anxieties and creating a story of the ecogothic. The translation of this text therefore opens this local tropical story to current discourses involved in analyzing global ecocritical predicaments.
Plastic Gothic: Frankenstein, Art and the Microplastic Monster
Authors: Glade-Wright Robyn
Published: September 2019

The contamination of life with plastic pollution and humanity’s lethargic response to the problem is an unfolding terror: a story of Gothic horror unfolding in contemporary times. The power of Mary Shelley’s Gothic novel Frankenstein looms over the current terror of plastic pollution to encourage changes to the materials we create, use and discard. In Frankenstein, a monster was spawned in a process that desecrates the act of creating new life. Similarly, in my work of art Microplastics Found in Human Embryo, the depiction of an embryo is desecrated by plastic contamination. Frankenstein was unable to control his monster, and, denied empathy and love, the monster killed Frankenstein’s loved ones and haunted its creator’s soul. As microplastics are largely unseen, and increasing exponentially, they are becoming a modern monster. Microplastics can cross the placenta and the blood brain barrier, endangering the life and health of our children, potentially robbing us of progeny, and the future of humankind. Over the past two hundred years, Frankenstein has functioned as a shadowy mnemonic tale, haunting scientists and technologists by reminding them to consider the impacts of their creations. Shelley’s message, if applied to the current dangers of the “Age of Plastic”, might help us to clean up plastic pollution and embrace sustainable materials. In this spirit, Microplastics Found in Human Embryo reveals a monstrous idea, which aims to help awaken us from complacency and convince humanity to form a relationship which sustains all forms of life on Earth.

Not Today, Old Man
Authors: Burrows Lianda
Published: September 2019

‘Not Today, Old Man’ was written to the journal’s call-out theme ‘Tropical Gothic’. Informed by these ideas and a long tradition of women’s writing from Austen to Atwood, ‘Not Today, Old Man’ interrogates the relationship between women and violence.Throughout most of the twentieth century, ongoing abuse of women in a domestic environment was not considered a mitigating factor in violent action performed against the perpetrator, or indeed ‘self-defence’, unless taken at the time of attack. Unable to physically shield themselves from their abusers, and without a legal defence should they seek to protect themselves outside the temporal boundary of a violent attack, women were in a sense imprisoned within these relationships. In the comparatively rare instance that a woman was the perpetrator of domestic violence, ‘Battered Woman Syndrome’ was not available for defence in the context of Australian provocation law until the end of the twentieth century (see R v Kontinnen 1991; R v Runjanjic 1992). It is worth considering that in this same era, a man making unwelcome sexual advances to another man was considered reasonable grounds for ‘self-defence’ (R v Green 1997).The landscape in ‘Not Today, Old Man’ is predominantly set in the tropics, but the story also alludes to the diversity of countryside and climate within Australia, both in the text itself and through allusions to authors like Gerald Murnane. The dark undertones of the piece are embedded in the depiction of these landscapes and the images they evoke. The oppressive heat, humidity, and comparatively low population of Australia’s tropical regions lends itself to gothic exploration. This dark undertone was modelled on writers like David Malouf, whose fiction and poetry have been significant in endowing Australia with a sense of mythology associated with its Northern environments. As Malouf has explained, re-mythologizing the postcolonial Australian landscape gives its diverse inhabitants a renewed, ‘symbolised place’ to ‘exist in’ (cited in Mulligan & Hill, 2001, p.110).

Published: September 2019

The mengkreng intersection is a very congested route because its location is near Nganjuk, Kediri and Jombang Regencies for the economic distribution of the West and East Java Provinces. Traffic engineering management is needed so that the intersection is not increasingly saturated. As a benchmark, traffic performance forecasting is carried out for 3 years from 2019 to 2022. Based on forecasting results, the Mengkreng intersection will decrease its DS value by carrying out the Kertosono - Kediri toll road development plan so that the DS value is below 1 (one). In 2019 the lowest DS was 0.79, while the highest DS was 1.61. While in 2022 the lowest DS is 0.45, while the highest DS is 2.72. The solution to deal with traffic congestion in 2045 is through traffic engineering and vehicle restrictions.

A Diversified Machine Learning Strategy for Predicting and Understanding Molecular Melting Points
Authors: sivaraman ganesh , Jackson Nicholas , Sanchez-Lengeling Benjamin , Vazquez-Mayagoitia Alvaro , Aspuru-Guzik Alan , Vishwanath Venkatram , de Pablo Juan
Published: September 2019

The ability to predict multi-molecule processes, using only knowledge of single molecule structure, stands as a grand challenge for molecular modeling. Methods capable of predicting melting points (MP) solely from chemical structure represent a canonical example, and are highly desirable in many crucial industrial applications. In this work, we explore a data-driven approach utilizing machine learning (ML) techniques to predict and understand the MP of molecules. Several experimental databases are aggregated from the literature to design a low-bias dataset that includes 3D structural and quantum-chemical properties. Using experimental and polymorph-induced uncertainties, we derive a tenable lower limit for MP prediction accuracy, and apply graph neural networks and Gaussian processes to predict MP competitive with these error bounds. To further understand how MP correlates with molecular structure, we employ several semi-supervised and unsupervised ML techniques. First, we use unsupervised clustering methods to identify classes of molecules, their common fragments, and expected errors for each data set. We then build molecular geometric spaces shaped by MP with a semi-supervised variational autoencoder and graph embedding spaces, and apply graph attribution methods to highlight atom-level contributions to MP within the datasets. Overall, this work serves as a case study of how to employ a diversified ML toolkit to predict and understand correlations between molecular structures and thermophysical properties of interest.

Mehmed Uzun as a Representative of Modern Kurdish Narrative
Authors: Abdulkarim Chiad A. , Saeed Ismael
Published: September 2019

This article is dedicated to the analysis of Mehmed Uzun’s initial Two novels, Tu (1985) and Mirina Kalekî Rind (1987). It focuses on Mehmed Uzun as a representative of modern Kurdish narrative. When it comes to the concepts of identity distortion in characters and their complicated state of mind, his novels can be a relevant subject matter for interpretation. In light of Mikhail Bakhtin’s theory of polyphony and the scholars who worked in his circle, this article explores the polyphonic aspects of Mehmed Uzun’s two initial novels. Through novelistic discourse analysis, it becomes apparent that the characters suffer from the dormant identity, which is locally given to them in Uzun’s diasporic fiction. Next, the discussion gives further details regarding polyphony and how problematic polyphony can be found in the novels mentioned above. Finally, this article sheds light on the notion of identity formation in the fictional novel and its relationship with the real world during the time the novels were written. It concludes that the entire representation of characters and settings in his novels leads to the production of a realistic novel with the consistent discourse that can be considered an objective view of a specific time in history which is undermined.

Multifactor Authentication and Key Management Protocol for WSN-assisted IoT Communication
Authors: Ara Tabassum , Prabhakar M.
Published: September 2019

In this paper a novel multi-factor authentication protocol for IoT applications, relying on enhanced Rabinassisted elliptic curve cryptography, biometric features and time stamping methods, is developed. Furthermore, a fuzzy veriﬁcation algorithm has been developed to perform receiverlevel user veriﬁcation, making computation eﬃcient in terms of computational overhead as well as latency. An NS2 simulation-based performance assessment has revealed that the multifactor authentication and key management models we have proposed are capable of not only avoiding security breaches, such as smart card loss (SCLA) and impersonation attacks, but can also ensure the provision of maximum possible QoS levels by oﬀering higher packet delivery and minimum latency rates.
A Novel Graph-modiﬁcation Technique for User Privacy-preserving on Social Networks
Authors: Erfani Seyedeh Hamideh , Mortazavi Reza
Published: September 2019

The growing popularity of social networks and the increasing need for publishing related data mean that protection of privacy becomes an important and challenging problem in social networks. This paper describes the (k,l k,l k,l)-anonymity model used for social network graph anonymization. The method is based on edge addition and is utility-aware, i.e. it is designed to generate a graph that is similar to the original one. Diﬀerent strategies are evaluated to this end and the results are compared based on common utility metrics. The outputs conﬁrm that the na¨ıve idea of adding some random or even minimum number of possible edges does not always produce useful anonymized social network graphs, thus creating some interesting alternatives for graph anonymization techniques.
Antioxidant and anti-inflammatory dietary supplements in the treatment of
osteoarthritis: a scoping review
Authors: Ong Y.Q. , Sakinah H. , Shahril M.R. , S. Norshazila
Published: September 2019

The increasing number of evidence has reported inflammation and oxidative stress as key
mediators of osteoarthritis (OA) joint pathology. Therefore, the usage of dietary
supplements targeting inflammation and oxidative stress in OA may emerge as a
rewarding therapeutic strategy. This study aimed to explore the efficacy of antioxidant and
anti-inflammatory dietary supplements used to manage OA. A methodological framework
proposed by Arksey and O’Malley was used to conduct this scoping review. An electronic
database search of English academic articles was conducted using PubMed, MEDLINE
and ScienceDirect from 2000 to 2018. Randomized controlled trials (RCTs) of OA with
parallel groups by comparing dietary supplements with placebo consumption were eligible
for inclusion. Out of 69,150 studies identified, a total of 41 studies were included, with 25
antioxidant or anti-inflammatory dietary supplements identified. There were 3325
respondents (1740 in the treatment group and 1585 in the placebo group), all aged ≥ 25
years old and comprised of 69.6% and 30.4% female and male respondents, respectively.
The majority of the studies recruited participants with knee OA (n = 33) with a follow-up
duration of 3 to 32 weeks. Overall, most of the dietary supplements (n =17) demonstrated
a beneficial effect on the clinical signs and symptoms, such as Boswellia serrata extract
(BSE), Pycnogenol and L-carnitine. In contrast, Aquamin supplementation did not exert
positive impacts on OA management, while inconsistent findings were observed in greenlipped mussel (GLM) extract, vitamin E, methylsulfonylmethane (MSM), licorice
flavonoid oil (LFO), ginger, willow bark extract and rose hip supplementation. In
summary, the role of anti-inflammatory and antioxidant dietary supplements cannot be
ignored as they can offer alleviated pain and symptom relief.

El objetivo del estudio fue evaluar las tecnologías de impresión 3D realizadas por Modelado Deposición Fundida (FDM) y PolyJet, a partir de ensayos mecánicos con materiales de Acrilonitrilo Estireno Acrilato (ASA) y VeroWhitePlus RGD 835 para la selección del material y tecnología adecuada en la fabricación de ductos de aire aplicados a autopartes automotrices. Con el fin de alcanzar el objetivo se realizaron pruebas de tracción mecánica a probetas fabricadas por ambas tecnologías; según la norma ASTM D638-14 para las pruebas de tracción y para los ensayos a flexión con la norma ASTM 790; para evaluar el comportamiento del flujo del aire en ducto se seleccionó como caso de estudio el ducto de aire empleado en la camioneta pick up Toyota Stout 2200 modelado por medio del software Ansys Student. Los resultados mostraron que el material VeroWhitePlus RDG 835 utilizado en la construcción del ducto por medio de la tecnología PolyJet presentó los mejores resultados con límite de fluencia a la tracción de 4.7 MPa y esfuerzo máximo de flexión de 28 MPa.
BRICS-T ÜLKELERİNDE EKONOMİK BÜYÜME VE KÜRESELLEŞME İLİŞKİSİ*
Authors: TEKBAŞ Murat
Published: September 2019

Dünya
ekonomik sistemi üzerinde ciddi etkisi olan küreselleşmenin ülkeler üzerinde
etkisinin farklı olduğu görülmektedir. Küreselleşme ile ülkeler arasında oluşan
yoğun ekonomik, sosyal ve politik ilişkiler ülkelerin ekonomik büyüme
performansı üzerinde de olumlu ya da olumsuz etkiler ortaya çıkarmaktadır. Bu
çalışmada küreselleşmenin ekonomik büyüme üzerindeki etkisinin BRICS-T ülkeleri
için incelenmesi amaçlanmaktadır. Bu doğrultuda, küreselleşmenin reel GSYH
üzerindeki etkisi, 1990-2014 dönemi için Pedroni ve Kao eşbütünleşme testi ve FMOLS
katsayı tahmincisi aracılığıyla incelenmiştir. Değişkenler arasındaki
nedensellik ilişkisi ise Dumitrescu ve Hurlin (2012) Panel Granger Nedensellik
Testi ile araştırılmıştır. Ayrıca, ampirik modelin Cobb-Douglas üretim
fonksiyonuna dayalı olarak kurulması nedeniyle sermaye değişkeni de modele
bağımsız değişken olarak dahil edilmiştir. Çalışmada elde edilen bulgular
sonucunda küreselleşmenin ve sermayenin birikiminin milli gelir üzerinde
etkisinin pozitif olduğu görülmüştür. Değişkenler arasındaki nedensellik
ilişkisi incelendiğinde kişi başına düşen sermaye birikimi ve ekonomik büyüme
arasında çift yönlü, küreselleşmeden ekonomik büyümeye doğru tek yönlü, kişi
başına düşen sermaye birikiminden küreselleşmeye doğru tek yönlü nedensellik
ilişkisi olduğu görülmüştür. Bu doğrultuda ülkelerin küreselleşme seviyelerinin
yükseltilmesinin ülkelerin ekonomik büyümelerinde avantaj sağlayacağı
değerlendirilmektedir.

Finansal raporlama için standartlaştırma
çalışmaları son yıllarda küresel düzeyde büyük önem kazanmaya başlamıştır. Bu doğrultuda, 2013/34
Sayılı AB Direktifinde yer alan “önce küçükleri düşün” yaklaşımının bir sonucu
olarak İngiltere’de orta ölçekli işletmeler için FRS 102 ve mikro işletmeler
için FRS 105 standartları yayımlanmıştır. Bu standartlar, finansal raporların
standartlaştırılması konusunda UMS/UFRS’yi takiben atılmış en önemli adımlar
olarak değerlendirilebilir. Türkiye’de de Kamu Gözetimi Muhasebe ve Denetim
Standartları Kurumu (KGK) tarafından FRS 102 referans alınarak Büyük ve Orta
Ölçekli İşletmeler İçin Finansal Raporlama Standardı (BOBİ FRS) hazırlanmış ve 29.07.2017
tarihinde Resmî Gazete’de yayımlanarak yürürlüğe girmiştir. 2019 yılında ise
yine KGK tarafından FRS 105 standardı referans alınarak Küçük ve Mikro
İşletmeler İçin Finansal Raporlama Standardı (KÜMİ FRS) taslak olarak
yayımlanarak kamuoyu görüşüne açılmıştır. Bu çalışmada, 2021 yılında yürürlüğe
girmesi planlanan KÜMİ FRS’nin temel konularda BOBİ FRS ve TMS/TFRS setlerinden
farklılaştığı yönlerin açıklanması amaçlanmıştır. Bu amaç doğrultusunda; KÜMİ
FRS seti taslağının BOBİ FRS setindeki karşılığı olan bölümlerle ve TMS/TFRS
setindeki karşılığı olan standartlarla karşılaştırması yapılmış ve böylece
uygulayıcılara rehberlik sağlayacak bir çerçeve sunulmuştur. Çalışmanın
sonucunda; henüz taslak olarak sunulan KÜMİ FRS setinin yürürlüğe girmesi ile
birlikte, Türkiye’deki finansal raporlamanın standartlaşma yönünde nasıl bir
ilerleme kaydettiği değerlendirilmiştir.

Alojzego Felińskiego stosunek do pieniędzy i dóbr materialnych
Authors: Patro-Kucab Magdalena
Published: September 2019

Materiał badawczy stanowią wybrane fragmenty epistolografii Alojzego Felińskiego, poety tworzącego na przełomie XVIII i XIX wieku. Do analizy wybrano korespondencję, którą poeta prowadził z Michałem Wyszkowskim, Adamem Jerzym Czartoryskim oraz Janem i Walerią Tarnowskimi, a także Franciszkiem Rudzkim. Celem artykułu jest zwrócenie uwagi na wartość dóbr materialnych w życiu Felińskiego; w badaniu poddano obserwacji poetycki rodzaj argumentowania, z jednej strony charakterystyczny dla prezentowanego twórcy, z drugiej zaś – często pośrednio – ujawniający stosunek poety wobec pieniędzy. Autorka, biorąc pod uwagę kontekst historyczny oraz biograficzny, a także perswazyjność wypowiedzi wołyńskiego poety, próbuje wyjaśnić, na czym polega zdroworozsądkowe myślenie Felińskiego zarówno o pieniądzach, jak i materialnych dobrach.
Los rediseños curriculares en las carreras: un diálogo abierto en la Facultad de Filosofía, Letras y Ciencias de la Educación
Authors: Barreno Freire Segundo , Borja Naranjo Germania , Jaramillo Jaramillo Cecilia
Published: September 2019

El propósito del estudio fue identificar las percepciones de estudiantes y docentes sobre las dificultades de la implementación de los rediseños curriculares en la Facultad de Filosofía, Letras y Ciencias de la Educación de la Universidad Central del Ecuador, para lo cual se tomó como base para el análisis las funciones sustantivas de la educación superior que son: docencia, investigación y vinculación con la sociedad. La metodología contempló el enfoque naturalista de carácter exploratorio y descriptivo, se utilizaron técnicas cualitativas y cuantitativas para lo cual se elaboró un formulario de encuesta en escala de Likert y una guía de grupo focal. La investigación consideró aspectos como: participación de la comunidad educativa en la elaboración e implementación de los rediseños curriculares; la docencia, la investigación y la práctica preprofesional en los rediseños; el aporte del proyecto integrador de saberes y las prácticas de aplicación y experimentación al perfil de egreso. Los resultados evidenciaron que en la elaboración e implementación del rediseño existió una limitada participación de los actores clave, además se evidenció una deficiente orientación pedagógica y curricular. Esto se expresa en debilidades sustanciales en los campos de especialidad y de formación docente, en las mallas curriculares con asignaturas de alta carga horaria, que no corresponden al campo específico de la especialidad; así como también, la poca comprensión sobre los alcances y objetivos del proyecto integrador de saberes. Una de las conclusiones más importante apunta a una reforma integral a los rediseños curriculares de las carreras que respondan al perfil de egreso en coherencia con los lineamientos pedagógicos, epistémicos, metodológicos y axiológicos de la Facultad.

Published: September 2019

Este artículo describe el proceso experimental realizado en la obtención de la luminancia de dos tipos de focos, el de incandescencia y el fluorescente en un mismo ambiente físico. Para realizar el mencionado estudio se eligió el método punto a punto, el cual, permite conocer la luminancia en puntos concretos de una superficie bajo una fuente de luz que se ubica a una determinada altura.  Además, se trata de conocer el grado de confort visual del sentido de la vista en un lugar de iluminación uniforme.  Los resultados obtenidos permiten realizar diversas comparaciones en el uso de una determinada lámpara, tomando en cuenta la que más beneficios presenta en función de ofrecer un nivel de luminancia y un confort visual apropiado, un ahorro económico y una fácil obtención y reemplazo.

La experiencia en el aprendizaje de Luz e Iluminación en busca de un aprendizaje significativo evoca conocimientos previos tales como: flujo, intensidad, ángulo sólido y luminancia con el objetivo de entender el fenómeno, presentar una nueva información y hacer un feedback en busca de una nueva información que acreciente su pensamiento en la vida cotidiana. Con los resultados obtenidos en la presente investigación se desea contribuya al mantenimiento de las luminarias de las aulas de la Carrera de Pedagogía de las Ciencias Experimentales Matemática y Física de la Universidad Central del Ecuador, las mismas que tienen características físicas similares al lugar en el cual se realizó la experiencia.
