Kamuda Büyük Veri: Alglar, Beklentiler ve Uygulamalar

3rd International Conference on Computer Science and Engineering (UBMK) (2018: Sarajevo, Bosnia & Herceg)Big Data is one of the most commonly encountered buzzwords among IT professionals nowadays. Technological advancements in data acquisition, storage, telecommunications, embedded systems and sensor technologies resulted in huge inflows of streaming data coming from variety of sources, ranging from financial streaming data to social media tweets, or wearable health gadgets to drone flight logs. The processing and analysis of such data is a difficult task, but as appointed by many IT experts, it is crucial to have a Big Data Implementation plan in today's challenging industry standards. In this study, we performed a survey among IT professionals working in the public sector and tried to address some of their implementation issues and their perception of Big Data today and their expectations about how the industry will evolve. The results indicate that most of the public sector professionals are aware of the current Big Data requirements, embrace the Big Data challenge and are optimistic about the future

PLDA-based diarization of telephone conversations

This paper investigates the application of the probabilistic linear discriminant analysis (PLDA) to speaker diarization of telephone conversations. We introduce using a variational Bayes (VB) approach for inference under a PLDA model for modelling segmental i-vectors in speaker diarization. Deterministic annealing (DA) algorithm is imposed in order to avoid local optimal solutions in VB iterations. We compare our proposed system with a well-known system that applies k-means clustering on principal component analysis (PCA) coefficients of segmental i-vectors. We used summed channel telephone data from the National Institute of Standards and Technology (NIST) 2008 Speaker Recognition Evaluation (SRE) as the test set in order to evaluate the performance of the proposed system. We achieve about 20% relative improvement in Diarization Error Rate (DER) compared to the baseline system

Identification of the Gram Positive Bacterial Sepsis Agent with Rapid Genotype Test

Objective: An irreversible process begins when a systemic infection causes sepsis. Therefore, rapid identification of the agent bacteria in sepsis and its antibiotic resistance is crucially important. In this study, it was aimed to investigate the efficiency of rapid genotype test in detecting sepsis agent Gram positive bacteria and important antibiotic resistance. Methods: 2132 blood culture samples sent to the laboratory were examined with an automatic blood culture system (BACTEC, BD, USA) between 2018-2019. Blood culture bottles sent to the laboratory were Growing bacteria was identificated by VITEK (bioMerieux, France) automated bacteria identification / antibiotic susceptibility system. In addition, bacterial species and mecA, vanA, vanB, vanC1, vanC2 / C3 genes in blood cultures with Gram positive bacterial growth were also determined by the Genotype (R) BC Gram-positive (Hain Lifesience, Germany) test. Results: 72 patients with gram-positive bacteria growth in two or more blood culture bottles were included in the study. In 44 of the samples (61%) the same bacterial species were detected with conventional method (bacteria culture) and BC Gram positive test. In 28 of the samples (39%) differences were detected between results of methods regarding bacterial species name or vancomycin/methicillin resistance rate. Although single agent was isolated with culture method in all of the samples, multiple agents were detected in eight samples with rapid genotype test. Also, it was found that in mecA positive samples, ciprofloxacin resistance was higher than mecA negative ones. Conclusions: In the study, it was observed that BC Gram positive test could correctly identify sepsis agent bacteria and their resistance genes within 4-5 hours.Duzce University Scientific Research Projects CoordinationDuzce University [017.04.01.618]This research was supported by Duzce University Scientific Research Projects Coordination; with the project title Identification and resistance determination in blood cultures with a growth of gram positive bacteria with genotyping, number 017.04.01.618.WOS:00070904020000

The influence of airway supporting maneuvers on glottis view in pediatric fiberoptic bronchoscopy

Introduction: Flexible fiber optic bronchoscopy is a valuable intervention for evaluation and management of respiratory diseases in both infants, pediatric and adult patients. The aim of this study is to investigate the influence of the airway supporting maneuvers on glottis view during pediatric flexible fiberoptic bronchoscopy. Materials and methods: In this randomized, controlled, crossover study; patients aged between 0 and 15 years who underwent flexible fiberoptic bronchoscopy procedure having American Society of Anesthesiologists I–II risk score were included. Patients having risk of difficult intubation, intubated or patients with tracheostomy, and patients with reduced neck mobility or having cautions for neck mobility were excluded from this study. After obtaining best glottic view at the neutral position, patients were positioned jaw trust with open mouth, jaw trust with teeth prottution, head tilt chin lift and triple airway maneuvers and best glottis scores were recorded. Results: Total of 121 pediatric patients, 57 girls and 64 boys, were included in this study. Both jaw trust with open mouth and jaw trust with teeth prottution maneuvers improved the glottis view compared with neutral position (p < 0.05), but we did not observe any difference between jaw trust with open mouth and jaw trust with teeth prottution maneuvers (p > 0.05). Head tilt chin lift and triple airway maneuvers improved glottis view when compared with both jaw trust with open mouth and jaw trust with teeth prottution maneuvers and neutral position (p < 0.05); however we found no differences between head tilt chin lift and triple airway maneuvers (p > 0.05). Conclusion: All airway supporting maneuvers improved glottic view during pediatric flexible fiberoptic bronchoscopy; however head tilt chin lift and triple airway maneuvers were found to be the most effective maneuvers. Resumo: Introdução: A broncofibroscopia flexível (BF) é uma valiosa intervenção para o manejo e avaliação de doenças respiratórias em pacientes tanto pediátricos quanto adultos. O objetivo deste estudo foi investigar a influência das manobras de apoio das vias aéreas sobre a visibilidade da glote durante a BF pediátrica. Material e método: Estudo cruzado, randômico e controlado, incluindo pacientes com idades entre 0-15 anos, ASA I-II, que foram submetidos à BF. Pacientes com risco de intubação difícil, entubados ou com traqueostomia e aqueles com mobilidade reduzida do pescoço ou que exigissem cuidados para a mobilidade do pescoço foram excluídos do estudo. Depois de obter a melhor visibilidade da glote na posição neutra, os pacientes foram posicionados com elevação da mandíbula e abertura da aberta (EMBA), com elevação da mandíbula e protrusão dos dentes (EMPD), com inclinação da cabeça elevação do queixo (ICEQ) e com a tripla manobra das vias aéreas (TMVA). Os melhores escores da glote foram registrados. Resultados: No total, 121 pacientes pediátricos foram incluídos no estudo: 57 pacientes do sexo feminino e 64 do sexo masculino. Ambos as manobras EMBA e EMPD melhoraram a visibilidade da glote em comparação com a posição neutra (p < 0,05), mas não observamos diferença entre as manobras EMBA e EMPD (p > 0,05). As manobras ICEQ e TMVA melhoraram a visibilidade da glote em comparação com as manobras EMBA e EMPD e a posição neutra (p < 0,05); porém, não encontramos diferenças entre a ICEQ e a TMVA (p > 0,05). Conclusão: Todas as manobras de acesso às vias aéreas melhoraram a visibilidade da glote durante a BF pediátrica; porém, a inclinação da cabeça e elevação do queixo e a tripla manobra das vias aéreas foram consideradas as manobras mais eficazes.
