Automatically evolving difficult benchmark feature selection datasets with genetic programming
Authors: Lensen Andrew , Xue Bing , Zhang Mengjie
Published: October 2020

© 2018 Copyright held by the owner/author(s). There has been a wealth of feature selection algorithms proposed in recent years, each of which claims superior performance in turn. A wide range of datasets have been used to compare these algorithms, each with different characteristics and quantities of redundant and noisy features. Hence, it is very difficult to comprehensively and fairly compare these feature selection methods in order to find which are most robust and effective. In this work, we examine using Genetic Programming to automatically synthesise redundant features for augmenting existing datasets in order to more scientifically test feature selection performance. We develop a method for producing complex multi-variate redundancies, and present a novel and intuitive approach to ensuring a range of redundancy relationships are automatically created. The application of these augmented datasets to well-established feature selection algorithms shows a number of interesting and useful results and suggests promising directions for future research in this area.

Published: October 2020

© 2019, © 2019 The Royal Society of New Zealand. Artificial intelligence (AI) emphasises the creation of intelligent machines/systems that function like humans. AI has been applied to many real-world applications. Machine learning is a branch of AI based on the idea that systems can learn from data, identify hidden patterns, and make decisions with little/minimal human intervention. Evolutionary computation is an umbrella of population-based intelligent/learning algorithms inspired by nature, where New Zealand has a good international reputation. This paper provides a review on evolutionary machine learning, i.e. evolutionary computation techniques for major machine learning tasks such as classification, regression and clustering, and emerging topics including combinatorial optimisation, computer vision, deep learning, transfer learning, and ensemble learning. The paper also provides a brief review of evolutionary learning applications, such as supply chain and manufacturing for milk/dairy, wine and seafood industries, which are important to New Zealand. Finally, the paper presents current issues with future perspectives in evolutionary machine learning.

STUDY OF PERINATAL MORTALITY IN TERM BREECH PRESENTATION WITH INCREASING CAESAREAN SECTION RATE
Authors: Padmavathi T. , Aruna
Published: October 2020

Breech presentation persists in 3-4% of all term deliveries. There is a threefold increase in perinatal mortality for breech infant delivered vaginally which is related to birth asphyxia and birth trauma. The most frequent cause of death in neonates delivered through breech is intracranial hemorrhage; so many obstetricians recommend caesarean section for breech presentation. It is a retrospective study regarding management of term breech presentation conducted in King George Hospital, Vishakhapatnam from 2012 to 2015 and the results are compared with a similar study conducted in 1981-1984.There is an increase in incidence of caesarean section and decrease in perinatal mortality in our present study when compared to previous study. Increase in caesarean section for breech delivery has decreased the overall incidence of perinatal mortality.

Published: October 2020

A discussão deste artigo faz parte do levantamento bibliográfico da tese de doutorado em andamento que está sendo realizado no Programa de Pós-graduação em Educação/PPGE da Universidade Federal da Paraíba/ UFPB e tem por objeto os motivos e os móbiles, como elementos inerentes aos movimentos cotidianos dos sujeitos populares, com o intuito de apreender alguma transformação densa (como significado e sentido) propositiva das ações em suas próprias vidas. Com este artigo, a proposta é discutir o inacabamento humano, a relação com o saber, compreendendo os motivos e os móbiles como elementos inerentes ao viver e ao conhecer dos sujeitos. A referência teórica central deste trabalho está nos conceitos de motivo e de móbile, abordados por Charlot (1983; 2000; 2001; 2013) e Hannoun (1998), e na compreensão da condição humana conforme Maturana, (2001; 2004; 2009; 2014) Freire (1989; 1998; 2005) e Morin (2008;2009).

O presente artigo objetiva apresentar as ações do NCPPEM e a atuação dos agentes participantes nas Oficinas de Matemática, os sentidos e significados dos encontros de pesquisas e elaboração das Oficinas de Matemática. Para Charlot, a partir do social se estabelece a condição humana. Nessa conjuntura, ressaltamos os saberes docentes. O processo de análise dos resultados, se deu com o agrupamento de palavras com significativa frequência emergidas do instrumento de coleta de dados (questionário) a partir das vozes dos sujeitos de pesquisa. Assim, entende-se, então, que a partir da lente da epistemologia charlotiana, é possível refletir sobre a formação de professores, do ponto de vista didático-metodológico, epistemológico e sócio-histórico-cultural.

Published: October 2020

Изучены продуктивные качества и продолжительность хозяйственного использования симментальских коров хозяйств Поволжья в зависимости от их принадлежности к внутрипородным производственным типам, генеалогическим линиям и сочетаемости (кроссов) линий. В стаде одного из исследованных хозяйств продолжительность продуктивного долголетия у коров молочного и молочно-мясного типов была дольше в сравнении с мясо-молочным на 17,3 – 18,9 мес., а пожизненный удой молока в среднем выше на 5,78 – 7,36 тыс. кг. Между пожизненным удоем коров разных внутрипородных типов и удоем за отдельные лактации имеется положительная связь (r = 0,38 – 0,64). В другом хозяйстве наибольшим продуктивным долголетием характеризовались животные, принадлежащие линии Флориана 374, которые превосходили средние показатели представительниц всех других линий по данному признаку на 0,31 – 1,06 лактации. Среди кроссированных линий неэффективным оказался кросс Циппер × Флориан. Потомки быков от всех других кроссов имели удои выше, чем коровы от данного подбора, на 48 – 889 кг.

Published: October 2020

Objective: Knowledge about the chemical properties of new introduced resin adhesive cements how can affect esthetic maintenance of indirect restorations are limited. The aim of this study was to evaluate the color stability of three different adhesive resin cements exposed to different beverages.
Methods: Total eigthy four specimens (n=7) of each adhesive resin cement (TheraCem, BisCem and Duolink) were prepared. All specimens were aged by distilled water (control group), coffee, green tea and white tea for 24 days. CIELAB coordinates were acquired by means with spectrophotometer (Vita Easyshade, Vita Zahnfabrik, Bad Sackingen,). Color differences (∆E) and whiteness index for dentistry (WID) were calculated. The values were analyzed by two-way ANOVA and Tukey honestly significant difference test was used to compare group (α=0.05).
Results: TheraCem showed highest ∆E values and Duolink lowest ∆E values after immersion in distilled water, coffee, green tea and white tea. All tested specimens indicated clinically unacceptable color changes (∆E) after 24 days immersion in coffee, green tea and white tea.
Conclusion: Ingredients and chemical interactions of adhesive resin cements can alter water permeability of material and so color stability significantly affected. After 24 days, all beverages caused clinically noticeable color changes for all adhesive resin cement groups.

Published: October 2020

Amaç: Diyabetik nöropati sıklıkla hastanın şikayeti olursa veya önlenebilecek komplikasyonlar gelişmişse tanı almaktadır. Tip 2 diyabetli (T2DM) hastalarda diyabetik periferik nöropati (DPN) varlığının bildirildiğinden daha sık olduğu hipotezinden yola çıkarak bu hasta grubunda DPN sıklığını ve ilişkili olduğu durumları araştırmayı planladık.
Yöntem: Diyabet polikliniklerimize başvuran 336 tip 2 diyabetli hasta çalışmaya alındı. Anamnezleri, demografik ve antropometrik bilgileri, kullandıkları ilaçlar ve laboratuvar verileri kaydedildi. Diyabetik nöropatiyi saptamak amacıyla MNSI (Michigan Neuropathy Screening Instrument) skorlaması ve Semmes-Weinstein monofilaman testi uygulandı.
Bulgular: Bu 336 hastanın (yaş ortalaması 57,9±10 yıl, %63,7’si kadın) ortalama diyabet süresi 9,5±7,8 yıldı. HbA1c, açlık kan şekeri ve vücut kütle indeksi ortalaması sırasıyla %8,7±2, 182±89 mg/dl ve 32±5,8 kg/m2 bulundu. DPN sıklığı %38,7 (n=130) saptandı. Daha önce nöropati tedavisi başlanmış olan 32 hasta (%9.5) ilaç kullanımları nedeniyle diğer analizlere katılmadı. Diyabetik nöropatisi olan grupla (n=107) olmayan grup (n=197) arasında kadın cinsiyet (%71 vs %59,9, p=0,054), yaş (60,6 yıl vs 55,9 yıl, p<0,001), diyabet süresi (15,2 yıl vs 5,7 yıl, p<0,001), açlık kan şekeri (207 mg/dl vs 167 mg/dl, p<0,001), HbA1c (%9,6 vs %8,1, p<0,001), hipertansiyon öyküsü, aterosklerotik kardiyovasküler hastalık öyküsü, diyabetik retinopati ve insülin kullanımı istatistiksel anlamlı olarak farklı bulundu.
Sonuç: Çalışmamızda tip 2 diyabeti olan hastalarda yaklaşık %40 oranında diyabetik periferik nöropati saptandı. Bu bulgular, T2DM hastalarının periferik nöropatinin tarama testleri ile rutin değerlendirilmesinin gerekliliğini vurgulamaktadır.

Hemolitik aktivite %3 glikozlu koyun kanlı agarda 37oC’de 48 saatlik, koagülaz aktivite tüp test metodu ile 37oC’de 4 saatlik, biyofilm oluşumu ise modifiye Christensen makro tüp metodu ile %8 glikozlu Sabouraud Dekstroz sıvı besiyerinde 37oC’de 48-72 saatlik inkübasyon sonrasında değerlendirilerek belirlenmiştir. Flukonazol, kaspofungin, mikafungin, vorikonazol ve amfoterisin B’ye karşı MIK değerleri VİTEK-2 otomatize sistem ile belirlenmiştir.
Bulgular: Suşların 23’ü periferik kandan, 7’si damar içi kateterden, 3’er adet periton ve idrardan, 2 adet tırnak örneğinden, 1’er adet plevra ve balgam örneklerinden izole edilmiştir. Biyofilm aktivitesi tüm suşların 32’sinde (%80) saptamış olup, 13’ü (%32,5) zayıf, 12’si (%30) orta, 7’si (%17,5) ise güçlü pozitif olarak skorlanmıştır. Suşların yarısı alfa hemoliz, 13’ü (%32,5) beta hemoliz gösterirken, 7’sinde (%17,5) hemoliz saptanmamıştır. Koagülaz aktivitesi tüm suşlarda negatif bulunmuştur. Tüm suşlar vorikonazol ve amfoterisin B’ye duyarlı saptanmıştır. Biyofilm aktivitesi zayıf olan iki suşta flukonazol direncine rastlanmıştır. Periferik kandan izole edilmiş 7 suş ile 2’si periton ve biri idrar suşu olmak üzere toplam 10 suşta (%25) kaspofungin direnci saptanmıştır. Bu suşların 4’ünde aynı zamanda mikafungin direnci, 7’sinde hemolitik aktivite ve biyofilm oluşumu gözlenmiştir. Antifungal direnci ile virülans faktörleri arasında istatistiksel olarak anlamlı bir ilişki bulunamamıştır.
Sonuç: Biyofilm oluşturma ve hemolitik aktivite C. parapsilosis’in başlıca virülans faktörleridir ve sıklıkla bu faktörlere bağlı olarak kandidemi ve kateter enfeksiyonları oluşabilmektedir. Bu enfeksiyonların tedavi protokolleri epidemiyolojik ve antifungal duyarlılık paterni verilerine göre değişim gösterebilir. Daha fazla C. parapsilosis suşu kullanarak ileri çalışmalar yapılması önerilmektedir.
Pseudostarlike and pseudoconvex Dirichlet series of the order $\alpha$ and the type $\beta$
Authors: Sheremeta M.M.
Published: October 2020

The concepts of the pseudostarlikeness of order $\alpha\in [0,\,1)$ and type $\beta\in (0,\,1]$ and the pseudoconvexity of order $\alpha$ and type $\beta$ are introduced for Dirichlet series with null abscissa of absolute convergence. In terms of coefficients, the pseudostarlikeness and the pseudoconvexity criteria of order $\alpha$ and type $\beta$ are proved.Let $h\ge 1$, $\Lambda=(\lambda_k)$ be an increasing to $+\infty$ sequence of positive numbers ($\lambda_1>h$. We call a conformal function of the form $F(s)=e^{sh}+\sum\nolimits_{k=1}^{\infty}f_k\exp\{s\lambda_k\}, \ s=\sigma+it,$in $\Pi_0=\{s\colon \, \text{Re}\,s<0\}$ pseudostarlike of order $\alpha\in [0,\,1)$ and type$\beta \in (0,\,1]$ if\begin{equation*}\left|\frac{F'(s)}{F(s)}-h\right|<\beta\left|\frac{F'(s)}{F(s)}-(2\alpha-h)\right|,\quad s\in \Pi_0.\end{equation*}The main results of the article are contained in Theorems 1 and 2. Theorem 1 states: \textit{If $\alpha \in [0, \, 1)$ and $\beta \in (0, \, 1]$ such that\begin{equation*}\sum\limits_{k=1}^{\infty}\{(1+\beta)\lambda_k -2\beta\alpha -h(1-\beta)\}|f_k|\le 2\beta (h-\alpha)\label{t7}\end{equation*}then the function $F$ is pseudostarlike of order $\alpha$ and type $\beta$.}The corresponding results for Hadamard compositions of such series are also established.
Truncation error bounds for branched continued fraction whose partial denominators are equal to unity
Authors: Dmytryshyn R. I. , Antonova T. M.
Published: October 2020

The paper deals with the problem of obtaining error bounds for branched continued fraction of the form $\sum_{i_1=1}^N\frac{a_{i(1)}}{1}{\atop+}\sum_{i_2=1}^{i_1}\frac{a_{i(2)}}{1}{\atop+}\sum_{i_3=1}^{i_2}\frac{a_{i(3)}}{1}{\atop+}\ldots$. By means of fundamental inequalities method the truncation error bounds are obtained for the above mentioned branched continued fraction providing its elements belong to some rectangular sets ofa complex plane. Applications are considered for several classes of branched continued fraction expansions including the multidimensional \emph{S}-, \emph{A}-, \emph{J}-fractions with independent variables.
Further results on Left and Right Generalized Drazin Invertible Operators
Authors: Messirdi So. , Messirdi Sa. , Messirdi B.
Published: October 2020

In this paper we present some new characteristics and expressions of left and right generalized Drazin invertible bounded operators on a Banach space $X.$ An explicit formula relating the left and the right generalized Drazin inverses to spectral idempotents is provided. In addition, we give a characterization of operators in $\mathcal{B}_{l}(X)$ (resp. $\mathcal{B}_{r}(X)$) with equal spectral idempotents, where $\mathcal{B}_{l}(X)$ (resp. $\mathcal{B}_{r}(X)$) denotes the set of all left (resp. right) generalized Drazin invertible bounded operators on $X.$ Next, we give some sufficient conditions which ensure that the product of elements of $\mathcal{B}_{l}(X)$ (resp. $\mathcal{B}_{r}(X)$) remains in $\mathcal{B}_{l}(X)$ (resp. $\mathcal{B}_{r}(X)$). Finally, we extend Jacobson's lemma for left and right generalized Drazin invertibility. The provided results extend certain earlier works given in the literature.
Em busca de explicações sobre Vocábulos Africanos: Uma investigação em alguns dicionários e/ou glossários brasileiros (1889-2006)
Authors: Vitorino César Costa
Published: October 2020

The book “In search of explanations about African words: an investigation in some Brazilian dictionaries and / or glossaries (1889-2006)” raises controversial and relevant questions about the usefulness of Africanism for Brazil and the delimitation between Afro-Brazilian and africanists studies. The work is one of the results of the work that the author has been developing throughout his long and rich academic life. The author shows enthusiasm for the study of Brazilian Africanism, especially in what concerns on the relationships that are established between words and culture.It shows the participation of African languages in the constitution of the Brazilian Portuguese lexicon, since it considers that studies in this area have been taking place very slowly. Therefore, this work intends to promote the production of future researches that discuss about the social place of African words in Brazilian Portuguese. It makes a point of which we should have no doubt in affirming - unequivocally and systematically - that one can speak of Brazilian Africanism. It takes as a starting point the analysis of dictionaries and glossaries (1889-2006), while taking a retrospective look.It reflects, with such observation, about what is classified as Africanism in the Brazilian Portuguese lexicon. It suggests the need to draw a line between Afro-Brazilian and Africanists studies. Finally, it is expected that such a work can bring new look and perspectives. It is even verified that, in his text, there is a lot of work for everyone. That´s why this work in this book is considered by the author as a singular value.

Pentingnya Pemuridan Bagi Pertumbuhan Gereja Pada Masa Kini
Authors: Harita Novi Saria
Published: October 2020

Penurunan moralitas atau penurunan karakter gereja merupakan hal yang perlu diperhatikan kembali oleh gereja saat ini. Perkembangan zaman yang semakin canggih berdampak negatif bagi gereja dan orang percaya. Kurangnya pengetahuan dan pemahaman anggota gereja tentang doktrin agama Kristen menghalangi anggota gereja untuk bertumbuh dewasa secara rohani.Gereja perlu lebih memperhatikan masalah yang terjadi di dalamnya. Salah satu masalah tersebut adalah kurangnya layanan pemuridan di gereja. Ini karena pemahaman gereja tentang Amanat Agung (Matius 28: 18-20) sangat sempit. Dimana gereja hanya memahami Amanat Agung (Matius 28: 18-20) sebagai tugas penginjilan atau kewajiban untuk menjangkau orang-orang yang tidak mengenal Kristus saja. Sehingga gereja membutuhkan pemahaman yang benar tentang Amanat Agung. Gereja yang akan menjalankan pemuridan harus berdasarkan kebenaran Firman Tuhan, sehingga tujuan pemuridan menjadi semakin seperti Kristus dapat tercapai.

Open Science (OS) increases the quality, efficiency, and impact of science. This has been widely recognised by scholars, funders, and policy makers. However, despite the increasing availability of infrastructure supporting OS and the rise in policies and incentives to change behavior, OS practices are not yet the norm. While pioneering researchers are developing and embracing OS practices, the majority sticks to the status quo. To transition from pioneering to common practice, we need to engage a critical proportion of the academic community. In this transition, Open Science Communities (OSCs) play a key role. OSCs are bottom-up learning groups of scholars that discuss OS practices, within and across disciplines. They make OS knowledge and know-how more visible and accessible, and facilitate communication among scholars and policy makers. By the same token, community members shape the transition to OS such that it is most beneficial for researchers, science, and society. Over the past two years, eleven OSCs were founded at several Dutch university cities, with approximately 700 members in total (at the time of writing). In other countries, similar OSCs are starting up. In this paper, we discuss the pivotal role OSCs play in the large-scale transition to OS and provide practical information on how to start a local OSC. We emphasize that, despite the grassroot character of OSCs, support from universities is critical for OSCs to be viable, effective, and sustainable.

Published: October 2020

The Spring term 2020 saw a global switch to emergency remote teaching in higher education due to the COVID-19 pandemic. Alongside asynchronous online learning activities, students were called to participate in synchronous videoconferencing sessions, substituting the traditional on-campus face-to-face courses. Given the preponderance of students to avoid using webcams, this study sought to investigate usage behavior, as well as potentially related course variables and individual characteristics. 3,527 students from across all institutional faculties of a comprehensive German university took part in an online survey. Students’ webcam usage behavior was related to personal thoughts and feelings (e.g., privacy), to course characteristics (e.g., group cohesion), and it differed due to specific groups (gender, study degree). Results of this research shed light on a globally present phenomenon and provide a foundation for further investigation.
Solitary and Joint Online Pornography Use During the First COVID-19 Lockdown in Portugal: Intrapersonal and Interpersonal Correlates
Authors: Rodrigues David L.
Published: October 2020

The onset of the COVID-19 pandemic forced several people into social isolation and research has shown a paradoxical effect on people’s sexual functioning. Some people experienced decreases in sexual desire and sexual satisfaction, whereas others experienced heightened sexual desire and made new additions to their sexual repertoire, including more online pornography use during the lockdown. Yet, studies failed to examine its interpersonal and intrapersonal correlates, distinguish between solitary and joint use, or explore differences between partnered and single people. We examined if changes in solitary or joint online pornography use since the lockdown were associated with sexual functioning, sexual satisfaction, perceived health, and sleep quality. We conducted an online cross-sectional study with convenience sampling in Portugal (N = 303 participants; 56.3% men; Mage = 31.32, SD = 10.55; 70.8% in a relationship) during May and July 2020. Partnered participants who reported increases in solitary online pornography use also reported decreases in their sex life quality. For partnered and single participants, increases in joint online pornography use were associated with increases in sex life quality. Single participants who reported increases in solitary online pornography use also perceived better health and sleep quality, and those who reported increases in joint online pornography use also reported more intimacy with casual partner(s) and better sleep quality. These findings suggest that online pornography was sometimes used as a sexual pleasure tool to connect with a stable or casual partner(s) in a time when social interactions were restricted.

Tactile perception plays a pivotal role in the early stages of human development; however, little is known about tactile function in young children. A better understanding of how tactile function improves with age from early childhood to adulthood is fundamental in understanding atypical tactile experiences in childhood-onset neurodevelopmental disorders, including autism spectrum disorder. In this study, one hundred and forty-two children and adults aged 3–23 years completed a vibrotactile testing battery consisting of five tasks, which rely on different cortical mechanisms. The battery was designed to be suitable for testing in young children and was used to investigate tactile perception from early childhood to adulthood. Our results show a general pattern of rapid, age-related improvements in tactile perception (lower discrimination threshold = greater sensitivity) across early childhood (ages 3–6 years). However, differences in the rate of change across tasks were observed, with tactile performance reaching adult-like levels earlier on same tasks than others. These findings highlight that early childhood is a period of rapid changes in tactile perception, and that the different underlying cortical, physical and cognitive development processes likely develop at different rates. Further, we are the first to show the feasibility of vibrotactile testing in an early childhood sample, which has important clinical implications for examining developmental disorders with altered tactile function and our results can be used as a reference.
The impact of a physician’s recommendation and gender on informed decision making: A randomized controlled study in a simulated decision situation
Authors: Eggeling Marie , Meinhardt Anna , Cress Ulrike , Kimmerle Joachim , Bientzle Martina
Published: October 2020

Objective: This study examined the influence of physicians’ recommendations and gender on the decision-making process in a preference-sensitive situation. Methods: N = 201 participants were put in a hypothetical scenario in which they suffered from a rupture of the anterior cruciate ligament (ACL). They received general information on two equally successful treatment options for this injury (surgery vs. physiotherapy) and answered questions regarding their treatment preference, certainty and satisfaction regarding their decision, and attitude toward the treatment options. Then participants watched a video that differed regarding physician’s recommendation (surgery vs. physiotherapy) and physician’s gender (female vs. male voice and picture). Afterward, they indicated again their treatment preference, certainty, satisfaction, and attitude, as well as the physician’s professional and social competence.Results: Participants changed their treatment preferences in the direction of the physician’s recommendation (P<.001). Decision certainty (P<.001) and satisfaction (P<.001) increased more strongly if the physician’s recommendation was congruent with the participant’s prior attitude than if the recommendation was contrary to the participant’s prior attitude. Finally, participants’ attitudes toward the recommended treatment became more positive (surgery recommendation: P<.001; physiotherapy recommendation: P<.001). We found no influence of the physician’s gender on participants’ decisions, attitudes, or competence assessments.Conclusion: This research indicates that physicians should be careful with recommendations when aiming for shared decisions, as they might influence patients even if the patients have been made aware that they should take their personal preferences into account. This could be particularly problematic if the recommendation is not in line with the patient’s preferences.

Published: October 2020

Introduction: Canalicular curettage is a surgical procedure used to remove canalicular contents and debris from canaliculi. It is usually indicated for chronic, persistent or recalcitrant canalicular diseases with no resolution of symptoms after conservative management. We describe 3 different cases of persistent canalicular diseases which needed canalicular curettage to rescue from the conditions leading to successful outcomes.
Cases and observations:• Case 1: A 45-year-old male presented with recurrent punctal granuloma 3 months after DCR surgery. Canalicular exploration and curettage with one-snip punctoplasty following excision of the mass revealed a segment of remnant silicone stent. There was no recurrence of mass in subsequent follow up visits.• Case 2: A 35-year-old female presented with recurrent canaliculitis for last 6 months. Canalicular curettage revealed multiple small calcified masses of varying size and shape. The patient had good postoperative recovery and showed no recurrence of symptoms.• Case 3: A 32-year-old female presented with gradually increasing pedunculated mass arising out of punctum for last one month. Excision of mass with canalicular curettage was done. Biopsy proved it to be squamous papilloma of the canaliculi. There was no recurrence of mass.
Conclusion: Canalicular curettage is a simple, safe and effective surgical intervention to rescue from the recalcitrant canalicular conditions like canaliculitits, retained foreign bodies, canalicular neoplasms leading to successful outcomes.
Bevacizumab in Retinopathy of Prematurity : Concerns and adverse effects
Authors: Sharma Anuj , Shetty Adheesh , Reddy Y.C. Venu Gopal
Published: October 2020

Retinopathy of prematurity (ROP) ranks as one of the leading causes of blindness in the paediatric age group, the incidence of which is increasing in developing countries as the economy strengthens and healthcare practices improve. As a vasoproliferative disorder affecting premature neonates VEGF is said to play a vital role in the pathogenesis of ROP. Evidence of the efficacy of anti-VEGF agents in treatment of ROP have been seen in literature since early 2007 with most published reports being either case studies or small case series. The only randomised controlled trial in this regard was the BEAT-ROP study which was published in 2011. However, even in that study the adverse effects of Bevacizumab were not analysed. This review aims to discuss the complications prior to the blanket administration of intravitreal bevacizumab in the management of ROP.

Authors: Rishi Ekta , Sood Gitanjli , Khurana Mona , Rishi Pukhraj
Published: October 2020

Introduction: Decompression retinopathy (DR) can have varied manifestations as retinal and vitreous hemorrhage, disc edema, and macular edema. Vein occlusion associated with choroidal detachment (CD) has not been reported so far as a feature of DR.

Case: We report a case of a 78 year old male with bilateral primary open angle glaucoma (POAG) on maximal topical medication with progressive field loss. Trabeculectomy with mitomycin C was done in the left eye, and the patient developed hypotony in the immediate postoperative period which was managed conservatively. After six weeks he developed CD, vein occlusion and macular edema. Thus, Anti VEGF was given and in other eye filtration surgery was done with all measures to avoid sudden hypotony. Patient still developed CD in the right eye. For which, he was given oral and topical steroids in tapering dose. After one month there was resolution of macular edema in the left eye and choroidal detachment resolved in both eyes and IOP was in lower teens in both eyes.

Conclusion: Venous stasis retinopathy and choroidal detachment can be the manifestations of decompression retinopathy following glaucoma filtering surgery. The advancement in imaging modalities now can help us find the pathogenesis of the condition and validation of previous hypothesis proposed. Early identification and management of retinopathy helps in resolution with good visual recovery.

Speicher- oder Berechnungseffizienz? Zur mentalen Repräsentation der Flexionsparadigmen
Authors: Sękowska Jolanta
Published: October 2020

Wie die flektierten Formen im mentalen Lexikon repräsentiert sind, ist ein Themenbereich, mit dem sich zahlreiche Studien seit etwa 20 Jahren befasst haben. Werden flektierte Formen als vollständige Einträge im Langzeitgedächtnis gespeichert und von dort aus abgerufen oder durch eine Berechnungsoperation gebildet? Welche Informationen über die interne Struktur der flektierten Wörter sind im mentalen Lexikon abgelegt? Der vorliegende Beitrag diskutiert die Frage nach der Repräsentation der morphologischen Beziehungen im Langzeitgedächtnis und der psychischen Realität von wortspezifischen Flexionsparadigmen aus der Perspektive der Speicher- und Berechnungseffizienz.
Niebezpieczny urok jednoznaczności — Paweł Smoleński Wnuki Jozuego (dydaktyka ostrzegawcza)
Authors: Koc Krzysztof
Published: October 2020

The author of the article stresses that what constitutes the purpose of humanistic education is showing the world from different perspectives and ambiguity as its inherent ingredient, which should be approached as both didactic and axiological challenge (especially in the light of concept of young people’s civic education). In this context he proposes to have a glance at cultural microcosm (of today’s Israel) described by Paweł Smoleński in his book published in 2019 entitled Wnuki Jozuego [Joshua’s Grandchildren]. The Polish author of reportages shows in the said book how — based on the example of Jewish Israeli settlers in the West Bank — dealing with religious, ethnic, and cultural diversity and experiencing them on the daily basis, paves the way for radical views and, consequently, for unifying the past, present, and the future. Many among Smoleński’s interlocutors/interviewees, however, touch upon the need for open dialogue, accepting otherness, and various outlooks on the most burning issues. Therefore, the story thus told may be treated as a warning against believing in only one righteous truth, as well as against the said belief’s negative influence on the sphere of public exchange of thoughts.

Authors: Teh S.C. , A. Asma’, , Hamid Jan J.M. , Yusof, H.M.
Published: October 2020

Introduction: Forest clearing for agriculture plantations and local community settlements may triggerfood insecurity, which causes poor development, predominantly in Orang Asli children. This cross-sectionalstudy was conducted to determine the relationships between food security and anthropometric and cognitivefunction among Orang Asli children in Temerloh, Pahang. Materials and methods: A total of one hundred andsixty-seven children (ages 7 to 11) from five selected Orang Asli villages (Kampung Sungai Enggang, KampungPenderas, Kampung Pasu, Kampung Lubok Wong, and Kampung Pian) were involved in this study. The foodsecurity index was assessed using the Radimer/Cornell Hunger and Food Insecurity Instrument.Anthropometric indices were based on height-for-age and BMI-for-age Z-scores, while cognitive performancewas tested using Raven’s Coloured Progressive Matrices (R-CPM). Results: A majority (91.6%) of therespondents reported some kind of food insecurity (12.6% household food insecure, 74.2% individual foodinsecure, and 4.8% child hunger). Rates of stunting, thinness, and overweight/obesity were 25.8%, 16.2%,and 18.0%, respectively. A majority (46.1%) of the children had average cognitive scores, followed by belowaverage (38.3%) and above average (15.6%), respectively. Height-for-age was significantly associated withcognitive function (p=0.008). Among sociodemographic factors, household size (p=0.007) and householdincome (p<0.05) were significantly associated with the food security index, whereas the educational statusof the child was significantly associated with height-for-age (p=0.013) and cognitive function (p=0.003).Conclusion: Food insecurity remains a risk factor for child development impairment in the Orang Aslicommunity. Undernutrition remains a major health concern among respondents; however, no associationwas found between food security index and cognitive function.
Competição interna na hierarquia construcional: um estudo do princípio da não sinonímia
Authors: Rosa Flávia Saboya da Luz , Oliveira Mariangela Rios de
Published: October 2020

Neste artigo, investigamos a variabilidade linguística em perspectiva construcional, com base no princípio da não sinonímia, nos termos de Goldberg (1995, 2006). A partir dos pressupostos da Linguística Funcional Centrada no Uso, e conforme se encontra em Traugott e Trousdale (2013) e Hilpert (2014), entre outros, postulamos que esse princípio pode ser refinado e relativizado, levando-se em conta a hierarquia construcional proposta por Traugott (2008). Assim, elegemos aqui como objeto de pesquisa um esquema específico do português, integrante do paradigma dos marcadores discursivos formados por elementos indutor-refreadores e afixoides de origem locativa, nos termos de Rosa (2019); trata-se da construção de subfunção refreador-argumentativa, codificada como [IndutR AfixLoc]RA, de que resultam dez construtos, que acabam competindo entre si no uso linguístico: alto lá, calma aí, calma lá, espera aí, espera lá, segura aí, segura lá, aguenta aí, aguenta lá e para aí. Na pesquisa da não sinonímia, voltamo-nos para a competição interna (OLIVEIRA, 2018) ocorrida no esquema, defendendo que, em determinados níveis hierárquicos construcionais, é possível a proposição de sinonímia virtual e sinonímia aparente, contudo, na instância de uso efetivo, em que propriedades extra e intralinguísticas moldam as interações, no âmbito do construto, não ocorre, de fato, sinonímia, dado que o sentido é contextualmente dependente.
A construção de predicado fórico no português do Brasil contemporâneo
Authors: Oliveira Vinícius Maciel de
Published: October 2020

Este artigo analisa a construção de predicado fórico com o verbo fazer, em dados do português do Brasil contemporâneo, com base em fundamentos teóricos e metodológicos da Linguística Funcional Centrada no Uso, orientada para a explicação dos processos de construcionalização e mudança construcional. As análises empreendias demonstram que tal construção estabelece relação fórica (anáfora ou catáfora) com algum predicado referente já mencionado, por ser mencionado ou do contexto situacional. A pesquisa revela, ainda, que o processo de referência a um predicado pode ocorrer por meio da repetição do referente, o que nos permite tratar o fenômeno, também, numa perspectiva da variação.

Authors: ÖZÇELİK Abdullah
Published: October 2020

In this study, it is aimed to determine and reveal a viable two-axis solar monitoring system that produces higher voltage output than a fixed panel. After intensive research, a small-scale solar panel, servo motors, arduino processor as controller, and a two-axis solar tracker using a transmitter wirelessly transmitting voltage feedback were carried out.
In addition, a 'Smart House' model that makes our current lives safer and more practical has been investigated. Remote control of the smart home system has been analyzed. For remote control of the smart home model, the IoT (Internet of Things) structure uses the MQTT Protocol, NodeMCU (ESP8266) Control Card and sensors of different features to build this structure. Signals from sensors are directed to MQTT Broker with the help of the NodeMCU (ESP8266) Control Card. Phone control is provided through the mobile app, which is written using QML and C++ languages in the QT Creator IDE.
Power transformer demand forecast with Box Jenkins ARIMA model
Authors: KUVAT Özlem , ADALI Ege
Published: October 2020

Demand forecasting is based on the principle of trying to forecast the demand for the outputs of enterprises in the field of manufacturing or service for the next periods. It requires the estimation of various future scenarios, if necessary, taking measures and taking steps, and during the application phase, the technique that is most suitable for the characteristics of the examined data set is selected and used. As a result of a healthy analysis carried out in this way, detailed plans and strict measures can be taken for the unknown, negative scenarios of the future.
This study analyzes the characteristics of a series of power transformers of a company operating in the electromechanical industry in the past years, and as a result of this analysis, the Box Jenkins Autoregressive Integrated Moving Average method (ARIMA), which best fits the results, is expected to occur for power transformers in the future. It was made to estimate the amount of demand.
Within the scope of this study, firstly, the most suitable model was tried to be determined by taking into consideration the past 132 months data of PTS. It was decided that the best choice among the alternative models was the ARMA (4,4) x (0,1) 12 model. The model was found to be stable and it was decided that the root mean square error (RMSE), mean absolute percentage error (MAPE) and Theil inequality coefficient values determined in the performance measurements were appropriate.
Energy Security- A Threat Assessment for Pakistan
Authors: Malik Salma , Fayyaz Shabana
Published: October 2020

Security and provision of energy are the cornerstone of any country sustainable development as well as the main drivers for economic and industrial growth. Countries, whether developed or developing, remain heavily reliant on energy resources, and energy security is gaining critical primacy for all concerned. Faced with a severe energy crisis for a long time, Pakistan has had to rely on oil-based expensive energy mix widening demand-supply gap, lack of integrated energy strategy and poor energy governance, despite being endowed with immense hydro, wind and solar energy potential. This study attempts to map Pakistan vulnerability to the impacts and challenges pertaining to energy security that constrains its socio-economic development and stability. It further explores the need to involve local community and business sector in formulating adaptation strategies and bridging policy-practice gaps to restructure energy policy and systems by shifting energy mix in favour of renewables and improving energy governance.
Extraction of Semantic Domains Through Corpus Tools
Authors: Khan Azka , Rasul Sarwet
Published: October 2020

The increased interest in the techniques of corpus linguistics in the first decade of 21st century was based on the most important premises, which are valid even today – investigation of larger datasets in less time. This article compares the results of different corpus techniques employed for exploring the dominant semantic domains in a corpus. These corpus techniques include use of word clouds, frequency lists and KWIC of a text. This study uses fictional discourse by Kamila Shamsie – namely Broken Verses (2005) – to illustrate the corpus methodology. In addition to different corpus techniques, this study also compares the usability of different corpus software for this purpose such as, Antconc (3.2.4), Nvivo 11, and Sketch Engine. This article will prove to be a good beginning point for the researchers exploring a text in any field of corpus linguistics and digital humanities.
