Authors:   MBA Student, College of Business and Economics, King Abdulaziz University, Jeddah, Saudi Arabia, Bugis Anas
Published: October 2022

The civilized and industrial development in The Kingdom of Saudi Arabia, through achieving the 2030 vision and creating a suitable environment for business, has attracted a lot of investments, businesses, and enterprises, which have created a highly competitive environment. This competitive environment has led company managers to search for ways to ensure continuity and superiority over their competitors. This research aims to assist people with interest in low-cost carriers (LCCs) in Saudi Arabia such as managers of LCCs and other stakeholders by providing them with information on the travelers’ perceptions that might be overlooked and could help to find solutions that lead to increase customer satisfaction and improve performance of the firm, or to abolish activities that could damage the reputation and performance. Survey questionnaires were distributed to 111 participants in The Kingdom of Saudi Arabia to assess their perceptions of overall service quality via applying modified SERQUAL model on LCCs (LCCSQUAL). Data were analyzed using SPSS software; it was found that there are several SERQUAL dimensions that need to be improved especially those items with the lowest scores. The research concludes with providing some proposals that may assist managers and interested readers in achieving their goals towards sustainability.
Interactive Documentaries (Representing Reality)
Authors:   A PhD researcher and documentary filmmaker at RMIT University, Melbourne, Australia., Aburghif Hsham
Published: October 2022

By analysing three interactive documentaries chosen as models and highlighting other international i-docs, this article explores the forms of storytelling used to create an interactive documentary on digital platforms by examining the prospects for employing its elements (contents, interactivity, mechanism and weaknesses and strengths). I determine to what extent interactive documentaries can affect representation. To understand this question, I focus on exploring and discussing some critical points: Does the interactive documentary make users/viewers pay more attention to the representation than traditional films? Does it motivate them to explore it as an artefact or an object? Does the representation process change users' moods and attitudes to express their engagement, interaction, experiences and understanding of the subject? The problem revolves around revealing and knowing the methods of employing digital media in interactive documentaries. At the same time, the importance of this article comes from the scarcity of media studies concerned with interactive documentaries. This article aims to attract the filmmakers to the various issues that interactive documentaries represent and take advantage of them—further, the influential power of the i-docs on public opinion. Additionally, the method used is descriptive and analytical of phenomena of the i-doc, the content analysis as a tool for data collection.

Vaccination is the most effective method in preventing infections and decreasing infection-related morbidity and mortality. In this study, health students' attitudes and thoughts about COVID-19 vaccines were evaluated. The study was conducted between January 18 and February 1, 2021. Ethics committee approval was obtained before starting study. Students who accepted to participate in study were asked to fill in the interview form via google questionnaire. Data were analyzed in SPSS 21 program, p <0.05 was considered significant. 637 of participants were women and mean age was 20.74±7.32 years. 13.78% of students reported that they had disease and 34.02% of them had a family history of the disease. 71.83% of students had confusion about vaccine, 37.44% stated that they trusted vaccine, and 48.29% reported that they thought it was effective. If vaccine will protect themselves, their family, and friends (86.70%); if vaccine will protect community (86.95%), and stated that they would be vaccinated if vaccine would bring the people back to normalization (88.90%). There were 346 (42.20%) students who wanted to be vaccinated against COVID-19. In the study, although students reported that they want to be vaccinated if COVID-19 vaccine will protect themselves, their family, friends and society, and return public to normalization; It was concluded that level of confidence in the vaccine and desire to be vaccinated were low. Multidisciplinary studies are needed to increase COVID-19 vaccination rates.

Published: October 2022

Coronavirus Disease-19 (COVID-19) pandemic, affected pregnant women as well as many people. Aim of this study is to compare complete blood count (CBC) parameters of pregnant women infected with COVID-19 to that of healthy pregnant women and determine their prognostic features. 142 pregnant women infected with COVID-19 and 46 healthy pregnant women, included in this retrospective case-control study. Patients infected with COVID-19 were grouped as mild, moderate and severe, according to the findings of oxygen saturation and lung involvement. Age, gestational age, gravida, hospitalization length and CBC parameters of the participants were compared, according to the groups. CBC test revealed that uninfected pregnant women had statistically lower level of white blood cell count (WBC, p=0.001), platelet count (p=0,024), neutrophil count (p=0,001), lymphocytes (p=0,005), monocytes (p=0,001) and platelecrit (p=0.007) than from infected pregnant women. Evaluation of pregnant women with COVID-19 grouped into 3 categories as mild, moderate and severe showed that age, gravida and hospitalization length were comparable between groups, WBC (p=0.012) and neutrophile (p=0.001) counts of mild group were significantly lower than moderate group and there was no significant difference between moderate and severe groups regarding WBC and neutrophile counts (respectively p=0,281, p=0.542). CBC analysis is simple, applicable, widely used and cheap laboratory method. CBC parameters seem as a candidate for predicting COVID-19 clinical course. However, larger sample sized prospective studies supporting this idea are required.

Published: October 2022

Most investigations on Parkinson’s disease (PD) focus on the basal ganglia and brainstem, whereas the cerebellum has often been overlooked. The cerebellum is critical for motor control and increasing evidence suggests that it may be associated with the pathophysiology of PD. The aim of this study was to describe cerebral and cerebellar volumes in patients with PD and to compare results with healthy subjects. In the present study, 18 patients with PD (8 female, 10 male) and 19 controls (9 females, 10 males) were included. Structural magnetic resonance (MR) imaging was performed in both groups with a 1.5 Tesla scanner. The images were analyzed using ImageJ software. Volumes were estimated via planimetry and threshold stereological methods. The mean total cerebral volumes were 943.19 ± 91.67 cm3 in control group and 909.83 ± 95.88 cm3 in patients. The mean total cerebellar volumes and the volume fractions were found 140.44 ± 21.68 cm3, 14.94 ± 2.17 % in control group and 140.52 ± 15.96 cm3, 15.52 ± 1.73% in patients, respectively. There were no significant differences found in terms of cerebral and cerebellar parameters. Our knowledge about cerebellum and PD interaction remains limited, although, the cerebellum is a potential target for some parkinsonian symptoms. Further investigations are needed to understand the role of cerebellum in PD using newly developing imaging techniques.

Published: October 2022

Various appendiceal stump closure techniques are used in laparoscopic appendectomy (LA). The purpose of this study was to investigate the safety and usefulness of the Hemolok clip for the closure of appendicular stumps in LA. From January 2015 to October 2018, a total of 87 consecutive patients underwent LA by three surgeons with planned use of Hemolok clips. In 9 (10.3%) patients, hemolok clips could not be used for the closure of the stump. The remaining 78 patients were included for analysis. The demographics, operation time, hospitalization time and complications were recorded. Of these 78 patients, 39 (50%) were male and 39 (50%) were female. The mean age was 28.55 ± 10.61 (18- 73) years and median operation time was 51.3 (30-160) minutes. Twenty-two (28.2%) of the patients had complicated appendicitis (perforated, necrotic). The median time until oral diet allowance was 10.48 (4-36) hours after surgery and median hospitalization time was 22.92 (6-72) hours. Postoperative complications were seen in 4 (5.1%) patients; two had abdominal pain, one had abdominal distention and one had trocar site infection. None of the complications were associated with the use of hemolok clips. None of the patients required reoperation. The appendiceal diameter was found to be greater in patients without hemolok closure compared to patients with hemolok closure (p = 0.003). The closure of the appendix stump with hemolok in LA is an appropriate, safe, fast and cost-effective technique. It is important to note that the appendix stump should not be extremely edematous or necrotic in order to be able to apply hemolok clips. Ideally, the stump should have a diameter smaller than 1 cm.

Published: October 2022

To contribute to the literature with a case of postpartum intracerebral hemorrhage following in vitro fertilization (IVF) treatment. A 41-year-old female patient presented to our clinic with the complaint of headache lasting for four days. It was determined that the patient underwent a cesarean section 10 days earlier and had received preoperative IVF treatment. Her general condition was moderate. She was cooperative and oriented but apathetic and drowsy. There was 4/5 paralysis in the right lower extremity and right arm. Her blood pressure was 197/115 mmHg. In the brain CT, there was an approximately 6x1.5 cm parenchymal hematoma and subarachnoid hemorrhage in the deep white matter in the left frontal region. The patient was followed up in the intensive care unit for five days, and then admitted to the ward following the improvement in her general condition and apathic findings. Although there are no risk factors for intracerebral hemorrhage that occurs after IVF, it can present with neurological sequelae during recovery. There is a need for detailed studies and meta-analyses that will guide both the treatment approach to these patients and preventive measures.

Published: October 2022

Considering the increased patient burden and disruptions in the healthcare system, orthopedic residents are affected both psychologically and physically while working both in the management of trauma patients and caring for COVID-19 patients. Our objective was to investigate the virus exposure and health status of orthopedic residents during the pandemic and to review the measures that can be taken. A survey consisting of 15 questions was organized and circulated through e-mail groups and social media platforms in order to evaluate the health status of residents. Demographic data, co-morbidities, whether they had a COVID-19 infection, time they work in orthopedics-related and COVID-related units, whether there was infection among their colleagues or family members and the infected patient care were questioned. A total of 136 residents completed the survey, of which 41 (30.1%) were infected. A significant difference was found between COVID-infected and COVID-free residents in terms of comorbidities (p=0.026). Residents with infection among their colleagues had lower infection rates (p<0.001). No significant difference was found between groups in terms of the working periods in orthopedics-related or COVID-related units (p>0.05 for each). With this study, the infection rate among orthopedic residents were reported for the first time in the literature, considering the fact that a third of all the participants in our study were infected. The infection rate among the orthopaedics residents were reported for the first time in the literature with this study. The fact that residents with infected colleagues have lower infection rates, demonstrates the importance of self-awareness and protective behaviors. During the pandemic, all healthcare professionals should pay maximum attention for simple measures, like practicing protective behaviors and use of personal protective equipment.

Метафорические модели концептуальной диады «свой – чужой» в разных типах дискурса (на материале английского языка)
Authors: Коренецкая Ирина Николаевна
Published: October 2022

Концептуальная диада «свой – чужой» представляет собой многомерное ментальное образование, транслирующее функции языка и коммуникации в целом, отражающее процесс познания себя через иное, чужое. Целью исследования является определение способов репрезентации и категоризации данной оппозиции в различных типах англоязычного дискурса. Контекстуальный и сравнительный анализ дискурса позволили установить, что категоризация окружающих объектов как «своих» или «чужих» представлена в метафорической и нарративной формах. Эмоциональность и оценочность – неотъемлемая черта языкового выражения диады «свой – чужой». Особенный интерес представляет метафорическая вербализация оппозиции «свой – чужой» в институциональных типах дискурса по причине их коммуникативного охвата и суггестивного потенциала. Институциональный дискурс содержит метафоры, которые отражают подвижность границы между «чужим» и «своим», возможность перехода «чужого» в разряд «своего». Метафоры показывают некую градацию чужого: «свой чужой», «незнакомый чужой» и «враждебный чужой».
Chiefs in Development in Ghana: A Study of two Contemporary Ghanaian Chiefs
Authors: S.B. Akakpo , M. Ismaila
Published: October 2022

The central government has been mandated by the citizens to promote development in all the sectors of the country. In spite of the government's responsibility of promoting development in the country, the private sector also has a role to play. Thus, Non-Governmental Organizations (NGOs), international development partners, civil society organizations, and faith-based organizations have all played diverse roles in promoting development in Ghana. However, a key stakeholder of development at both local and national levels is the Ghanaian chieftaincy system. In contemporary times, some chiefs have redefined their roles as agents of development. Using the qualitative approach and through the lens of modernization theory, this paper investigates the contributions of Otumfuo Osei Tutu II and AgbogbomefiaTogbeAfede XIV to development at both local and national levels. The paper argues that Otumfuo Osei Tutu II and TogbeAfede XIV are modern chiefs who have used their positions and experience to promote development in areas of education, health, business and industry, settlement of disputes, information and communication technology, and sports among others. The paper concludes that both chiefs are agents of development who complement the role of the central government in promoting development in Ghana.
The bullwhip effect in supply chains: Review of recent development
Authors: Rafati Elham
Published: October 2022

The bullwhip effect happens whenever the demand order fluctuations in the supply chain (SC) escalate as they are transferred up the SC. In fact, a small change in point-of-sale demand may be interpreted by SC participants as a much bigger variability in demand. This looks like a cracking a whip, where a small flick of the wrist may yield a large motion at the end of the whip. Misstate data from one side of a SC to the other part may yield substantial sloppiness. This includes increase in inventories, shortage of cash flow, weak customer satisfaction, etc. Enterprises may efficiently reduce the bullwhip effect by completely learning its root causes. This paper presents an overview on the concept and recent development of the bullwhip effect.

FACTORS PREDICTING INACCURACY BETWEEN FROZEN SECTION ANALYSIS AND POSTOPERATIVE PATHOLOGY RESULTS: A TERTIARY CENTER EXPERIENCE

ABSTRACT

Objective: To evaluate the diagnostic accuracy and to identify the factors determining the
inaccuracy between FS analysis and postoperative pathology results in our hospital.
Materials and Methods: This study included 1435 patients with pelvic masses who underwent surgical intervention and FS consultation.
Results: On univariate analysis, menopausal state, abnormal uterine bleeding, preoperative
serum Ca125 level, preoperative leukocyte value, preoperative neutrophil value, tumor size,
presence of cystic component, pathological findings in Doppler USG, ascites and cell type were found to have statistical significance for benign / borderline / malign discrimination.
Menopausal state (p<0.0001), preoperative serum Ca125 level (p<0.0001) and tumor size
(p<0.0001) were identified as independent predictors for determining inaccuracy between
intraoperative and postoperative pathological evaluation. Inconsistency increased 2.5 times
with a serum Ca125 > 35 IU/ml, 3.8 times with tumor size> 79 mm and 5 times in
postmenopausal patients. For the discrimination of benign / borderline / malign definitions, FS results and final pathology results were compatible in 1250 (87%) patients while it was not in 185 (13%) patients.
Conclusions: Increased preoperative serum Ca125 level was a predictor for inaccuracy between FS examination and postoperative pathology results. Also, tumor size ≥80 mm and menopausal state were related to misdiagnosis in FS results. Maximal effort should be done to minimize preventable errors during intraoperative FS analysis.

COVİD-19 Pandemisi Koşulları Dikkat Eksikliği Hiperaktivite Bozukluğu ve Otizm Spektrum Bozukluğu Tanısı Olan Çocukların Annelerini Etkiledi mi?
Authors: YAZLA Ece , ASAFOV Azad , OĞUZ Funda
Published: October 2022

Giriş: Çocukların dikkat eksikliği hiperaktivite bozukluğu ya da otizm spektrum bozukluğu hastalıkları olduğunda annelerinin yaşam kalitelerinin azaldığı, bakım veren yüklerinin arttığı bildirilmiştir. Biz koronavirüs pandemisi boyunca otizm spektrum bozukluğu ve dikkat eksikliği hiperaktivite bozukluğu tanılı çocuklar ile ruhsal açıdan sağlıklı çocukların annelerindeki psikososyal etkilenme, yaşam kalitesi ve bakım veren yükü değişikliklerini araştırmayı amaçladık.
Yöntem: Dahil edilme kriterlerine uygun annelere, araştırmacılar tarafından hazırlanmış olan veri ve anket formları https://docs.google.com/forms linki ile gönderildi.
Bulgular: Çalışmamıza 139 anne dahil edildi. Bunlardan 59’u sağlıklı, 32 si dikkat eksikliği hiperaktivite bozukluğu tanılı ve 48’i otizm spektrum bozukluğu tanılı çocuğa sahipti. Üç grupta da pandemi sürecinde yaklaşık her üç anneden biri çocuklarının bakımları ile ilişkili kendisini daha fazla yük altında ve her beş anneden biri çocukları ile birlikte iken kendisini daha fazla kısıtlanmış hissettiğini bildirmiştir. Tüm grupların yaşam kalitelerinin önemli oranlarda (%44,1, %46,9 ve %37,5) azaldığı bulunmuştur.
Sonuç: Biz pandemi döneminde otizm spektrum bozukluğu ve dikkat eksikliği hiperaktivite bozukluğu tanılı çocukların annelerinin sağlıklı çocuk annelerinden daha fazla etkilenmemiş olmalarını, pandemi öncesi maruz kaldıkları stresin oluşturmuş olabileceği sistemik duyarsızlaştırmaya bağlı olabileceğini düşündük. Bulgularımız yaşamları daima pandemidekine benzer kısıtlılıklar ve izolasyon ile geçen, psikiyatrik hastalığı olan çocuk annelerinin yaşadıkları zorluklara dikkat çekerek, çocukların tedavileri aşamasında annelere de destek verilmesinin gerekliliğini ortaya koymaktadır.

Light transport in complex scattering media: practical applications in 3D graphics, Sensing and Machine Learning
Authors: Doronin Alexander
Published: October 2022

Accurate modeling of optical radiation propagation and interactions with complex materials such as biological tissues is a key ingredient in a number of practical applications from 3D photorealistic computer graphics rendering to sensing and biomedical visualization. This talk considers development of the novel algorithms and their subsequent implementations capable of dealing with multilayered translucent materials such as human skin. Firstly, we outline the detailed theoretical procedures required to solve both vector Radiative Transport and Raytracing equations simultaneously using light's orbital angular momentum beyond traditional radiometry. We created and successfully implemented a dual, unbiased Monte Carlo approach working in synergy for photon transport and path tracing techniques while executing on novel specialized NVIDIA’s Graphics Processing Units (GPUs) which support Compute Unified Device Architecture (CUDA) and Real-Time Raytracing (RTX) capabilities. Secondly, we focus on a number of practical applications such as 3D immersive demos and comprehensive examples of translucent material renderings of photorealistic quality, advanced optical sensing and biomedical visualization applications, etc. We perform a formal comparison of the developed algorithms with known analytical solutions, data obtained during in vivo clinical studies as well as previously developed offline rendering approaches. Finally, we show how recent developments in Machine Learning (ML) methods could assist with acquisition of material properties, corresponding BSSRDFs (Bidirectional scattering-surface distribution function) and aid with light transport calculations.

Tıbbi görüntülerden beyin tümörünün algılanması araştırmacılar için aktif araştırma alanıdır. Tümör dokusunun çeşitliliği ve tümörün karmaşıklığı süreci zorlu hale getirmektedir. Bu çalışmada üç ayrı beyin tümörü veri kümesi oluşturulmuştur. Oluşturulan veri kümeleri iki boyutludur. Birinci veri kümesi 3 boyutlu görüntülerden 2 boyutlu görüntülere hiçbir değişiklik yapmadan dönüştürülen beyin tümörü veri kümesidir. İkinci veri kümesi birnci veri kümesindeki beyin harici kısımların yok edilmesiyle elde edilmiştir. Üçüncü veri kümesi ise beyin tümörünü daha iyi algılayabilmek için ikinci veri kümesi üzerinde görüntüyü keskinleştirip Gauss Filtresi ekleyerek elde edilmektedir. Buradaki amaç veri kümelerinin eğitim ve test sonuçlarına etkisini gözlemleyebilmektir. Bu çalışmada, beyin tömörü bölütlenirken ve algılanırken yeni Çekişmeli Üretken Ağ önerilmiştir. Önerilen yöntem beyin tümörünü manuel olarak değil otomatik bir şekilde yapabildiği için avantajlıdır. Önerilen yöntem SSimDCL (Supervised Similarity Dual Contrastive Learning) olarak adlandırılmıştır. Önerilen yöntem günümüzde derin öğrenme mimarileri arasında en iyi sonucu veren nnU-Net ile kıyaslanmaktadır. Kıyaslama yapılırken LPIPS ve PSNR yöntemleri tercih edilmiştir. Yapılan deneysel çalışmalar sonucunda önerilen yöntemin veri kümesi iyileştikçe daha iyi sonuçlar verdiği gözlemlenmiştir. nnU-Net yöntemi metriksel olarak daha iyi olmasına rağmen görsel sonuçlar duyusal olarak kıyaslandığında önerilen yöntemin daha iyi olduğu görülmüştür.

Authors: ALHATEMİ Rusul Ali Jabbar , SAVAŞ Serkan
Published: October 2022

One type of brain disease that significantly harms people's lives and health is stroke. The diagnosis and management of strokes both heavily rely on the quantitative analysis of brain Magnetic Resonance (MR) images. The early diagnosis process is of great importance for the prevention of stroke cases. Stroke prediction is made possible by deep neural networks with the capacity for enormous data learning. Therefore, in thus study, several deep neural network models, including DenseNet121, ResNet50, Xception, MobileNet, VGG16, and EfficientNetB2 are proposed for transfer learning to classify MR images into two categories (stroke and non-stroke) in order to study the characteristics of the stroke lesions and achieve full intelligent automatic detection. The study dataset comprises of 1901 training images, 475 validation images, and 250 testing images. On the training and validation sets, data augmentation was used to increase the number of images to improve the models’ learning. The experimental results outperform all the state of arts that were used the same dataset. The overall accuracy of the best model is 98.8% and the same value for precision, recall, and f1-score using the EfficientNetB2 model for transfer learning.

Günümüzde insanlar tek başlarına ev ve dış ortamlarda, spor yaparken veya günlük yaşamlarını sürdürürken çeşitli sebeplerden kaza geçirerek zor durumlarda kalabilmektedir. Ayrıca meskûn mahal dışında meydana gelen kayıp aramalarında da kaybolan kişi veya çocuğu bir an evvel bulunması çok önemlidir. Dolayısıyla bu tür acil ulaşılması ve tespit edilmesi gereken kişilere hızla ulaşılmaması durumlarında kalıcı sakatlıklar ve ölümler meydana gelmektedir. Bu çalışmada derin öğrenme yöntemlerinden olan YOLOv4 ve YOLOv4-tiny algoritmaları ile kazaya uğrayan ve kaybolan insanların tespit edilebilmesi için 2 adet yapay zekâ modeli geliştirilmiştir. Geliştirilen modülde kameradan gelen görüntüler yapay zekâ modelinden geçirilerek insanların düşme pozisyonları, ayakta durma ve oturma pozisyonları algılanmakta ve acil durum tespiti yapıldığında alarm durumuna geçilerek ilgili kişilere konum/görüntü bilgileri gönderilmektedir. Geliştirilen yapay zekâ modeline ait acil durum tespit başarım değerleri mAP cinsinden YOLOv4 için %99,04, YOLOv4-tiny ile geliştirilen model için %97,91 olarak elde edilmiştir. Geliştirilen yapay zekâ modülünün ev ortamında kullanımı mümkün olduğu gibi İHA’ larda kullanılabilmesi mümkündür. Bu çalışmada elde edilen prototipin 112 Acil Çağrı Merkezleri tarafından kullanılması ile ev veya dış ortamda meydana gelen acil durumların tespiti ve arama çalışmalarında faydalı olacağı düşünülmektedir.

Authors: ÇALIŞIR Bircan
Published: October 2022

Bu çalışma, Derin Öğrenme ve 5G ile oluşturulan veriler kullanılarak kanal tahmini için bir evrişimsel sinir ağının (CNN) nasıl eğitileceğini gösterir. Eğitilmiş CNN, fiziksel aşağı bağlantı paylaşılan kanal (PDSCH) demodülasyon referans sinyalini (DM-RS) kullanarak tek girişli tek çıkışlı (SISO) modunda kanal tahmini gerçekleştirilmiştir. Kanal tahmini için genel yaklaşım, iletim kanalı içine değeri bilinen referans pilot sembolleri eklemek ve daha sonra bu pilot sembolleri kullanarak kanal yanıtının geri kalanını enterpolasyon yapmaktır. Kanal tahmini yapmak için derin öğrenme teknikleri de kullanılabilir. Örneğin, PDSCH kaynak ızgarasını 2 boyutlu bir görüntü olarak görüntüleyerek, kanal tahmini problemini, CNN'lerin etkili olduğu gürültü giderme veya süper çözünürlüğe benzer bir görüntü işleme problemine dönüştürebilir. Bu çalışma, bu tür eğitim verilerinin nasıl oluşturulacağını ve bir kanal tahmini uygulamasında CNN'nin nasıl eğitileceğini gösterir. Ayrıca, lineer enterpolasyon ile alınan pilot sembolleri içeren görüntüleri işlemek için CNN kanal tahmininin nasıl kullanılacağını gösterir. Bu çalışma, pratik ve mükemmel tahmin edicilere kıyasla sinir ağı kanal tahmincisinin sonuçlarını görselleştirerek sona ermektedir.

Elektrik yükü ile manyetik akı arasındaki ilişkiyi tanımlayan ve uygulanan gerilime bağlı olarak direnci değişen iki uçlu bir elemanı temsil eden memristör (hafızalı direnç) elemanının keşfi, memristif sistemlerin temelini oluşturmuştur. Kondansatör ve indüktör elemanlarının memristif sistemlerle ilişkilendirilmesi ile memristif sistemlerin çalışma alanı genişletilmiş ve memristöre ek olarak memkapasitör (hafızalı kondansatör) ve memindüktör (hafızalı indüktör) olarak adlandırılan yeni hafızalı devre elemanları literatürde yerini almıştır. Memkapasitörün karakteristik davranışı, elektrik yükü ve voltaj olarak tanımlanan iki durum değişkeninde sıkışmış histeretik döngü şeklinde gösterilmektedir. Bu çalışmada, bir alçak geçiren filtre (AGF) devresinin analizi için memkapasitör elemanı ve onun emülatör devresi ele alınmıştır. Böylece standart kondansatörlü ve memkapasitörlü alçak geçiren filtre devrelerinin performans kalitesi karşılaştırılmıştır. Karşılaştırma sonucunda memkapasitör tabanlı alçak geçiren filtre devresinin klasik filtre devresine göre nispeten daha iyi filtreleme performansı sağladığı sonucuna varılmıştır. Ayrıca memkapasitörün standart kondansatöre göre devreden daha az akım çekmesi sonucunda memkapasitörün tükettiği reaktif gücün standart kondansatörün tükettiği reaktif güçten daha az olduğu gözlemlenmiştir. Bu katkılar, gelecekteki elektronik çalışmalar için umut verici sonuçlar sunmaktadır.

Published: October 2022

Este artigo discute o processo de formação continuada dos professores dos Centros de Educação Infantil (CEI) da rede parceira do município de São Paulo a partir da análise da Instrução Normativa nº 8 de 2022 que estipulou quatro horas semanais para formação em horário de trabalho. Mesmo sendo uma conquista dos profissionais um movimento de ajustes nos CEIs foi gerado como, por exemplo, estabelecer um rodizio entre professores e auxiliares de modo que o trabalho com os alunos não seja interrompido durante as formações e a elaboração, em tempo exíguo, um plano formativo. Refletir sobre esse processo partindo da consideração da experiência de um CEI da região central é o objetivo desse artigo. Para tanto, combinou-se na elaboração do texto análise documental, teórica e relato de experiência.  Pode-se apontar que a unidade utilizou-se da estrutura institucional existente para atender a Instrução sem perder de vista a cultura escolar constituída.

O conhecimento do comportamento fenológico de plantas cultivadas é uma importante ferramenta para avaliar as transformações relacionadas ao ciclo da cultura, auxiliando no manejo e tomada de decisões. O estudo teve como objetivo caracterizar os aspectos fenológicos de oito etnovariedades tradicionais de amendoim, cultivados por agricultores do município de Alta Floresta - MT. O estudo foi realizado de dezembro de 2019 a maio de 2020, compreendendo o ciclo completo das variedades. Para auxiliar no estudo fenológico, foi proposta uma escala para avaliação do desenvolvimento dos estádios fenológicos, com base em imagens digitais. Os eventos avaliados foram: germinação, aparecimento das primeiras folhas tetrafoliadas, aparecimento dos primeiros ramos, início da floração, aparecimento do ginóforo e maturação completa da vagem. A germinação dos acessos ocorreu entre 4 a 6 dias após a semeadura. O início da floração ocorreu aos 19 dias após a germinação no acesso UNEMAT 023, sendo considerado o mais precoce. Os acessos UNEMAT 021 e 022 apresentaram o menor ciclo fenológico, com a maturação completa sendo alcançada 100 dias após a germinação, enquanto o acesso UNEMAT 020 completou o ciclo em 169 dias, sendo o mais tardio. Foi verificado dois padrões fenológicos distintos entre as variedades tradicionais, com maior diferenciação a partir da fase reprodutiva. As variedades de porte semiereto apresentaram ciclo consideravelmente menor em relação às variedades UNEMAT 020 e 025, de porte rasteiro.

Introduction:- The coronary sinus is a collection of veins, joined together to form a large vessel that collects blood from the heart muscle (myocardium) 1. Most cardiac veins drain into the wide coronary sinus, 2 or 3 cm long, lying in the posterior atrioventricular groove between the left atrium and ventricle.2 The sinus opens into the right atrium between the opening of the inferior vena cava and the right atrioventricular orifice. An endocardial fold may guard the entrance of sinus valve of the coronary sinus or Thebesian Valve. The fold may be absent or may cover the ostium of the sinus completely or partially. Material & Method:- The present study was conducted in the anatomy department of medical college Baroda, Gujarat. One hundred formalin-fixed hearts specimens were taken for the study The dimensions of the coronary sinus ostium in millimetres was measured with the help of digital vernier calliper. Craniocaudal and transverse length were measured and recorded in Microsoft excel. Result :- In the current study, we observed that 58 hearts had the coronary sinus with a thebesian Valve and the rest 42 were without a thebesian Valve.

Published: October 2022

El procesamiento de textos de cualquier índole es una tarea de gran interés en la comunidad científica. Una de las redes sociales donde frecuentemente las personas se expresan libremente es Twitter, y por lo tanto, es una de las principales fuentes para obtener datos textuales. Para poder realizar cualquier tipo de análisis, como primer paso se debe representar los textos de manera adecuada para que, luego, puedan ser usados por un algoritmo. En este artículo se describe la creación de un corpus de representaciones de palabras obtenidas de Twitter, utilizando Word2Vec. Si bien los conjuntos de tweets utilizados no son masivos, se consideran suficientes para dar el primer paso en la creación de un corpus. Un aporte importante de este trabajo es el entrenamiento de un modelo que captura los modismos y expresiones coloquiales de Argentina, y que incluye emojis y hashtags dentro del espacio vectorial.
