Authors: Pushkarev G. S. , Kuznetsov V. A. , Guskova O. A. , Malishevsky L. M.
Published: December 2020

Aim. To develop and implement a decision support system for a software product – medical information system “1C: Medicine” in the form of calculator for assessment of the absolute risk of death from cardiovascular diseases (CVD) and to show the prospects of using this system for patients with coronary artery disease (CAD) after coronary stenting.

Material and Methods. The medical information system “1C: Medicine” software interface was developed in Tyumen Cardiology Research Center. It was designed to assess 10-year absolute total mortality risk from CVD in males of working age (Tyumen Risk Scale (TRS)) to provide medical decision support. The program was tested in 764 male patients from the Prospective Registry of Percutaneous Coronary Interventions (PCI). The mean age of patients was 56.9 ± 8.8 years. All death cases, recorded within a year after PCI (n = 23), were used as the status check variable. The following algorithms were chosen to compare the predictive accuracy of the integrated model: PROCAM and FRAMINGHAM. The Schwarz information test and ROC analysis data were used to assess the predictive accuracy of the models.

Results. The values of Schwarz’s criterion in males were 283 for TRS, 235 for PROCAM, and 490 for FRAMINGHAM model. AUC indicator for TRS was 0.655 (95% CI 0.510–0.800), suggesting the satisfactory quality of resulting model. AUC indicators for FRAMINGHAM and PROCAM algorithms were 0.599 (95% CI 0.442–0.757) and 0.653 (95% CI 0.509–0.796), respectively.

Conclusion. The created TRS, integrated into the medical information system with psychosocial factors, may be quickly and successfully implemented to determine mortality risk in CAD patients within one year after coronary stenting. The TRS has an advantage over the traditional FRAMINGHAM risk scale and non-inferior to the PROCAM scale. Therefore, TRS may be used as a medical decision support program.

Introduction. Postoperative atrial fibrillation (POAF) is one of the most common complications of coronary artery bypass grafting (CABG) and occurs in 25–65% of patients.

Aim. The study aimed to assess the predictive potential of preoperative risk factors for POAF in patients with coronary artery disease (CAD) after CABG based on machine learning (ML) methods.

Material and Methods. An observational retrospective study was carried out based on data from 866 electronic case histories of CAD patients with a median age of 63 years and a 95% confidence interval [63; 64], who underwent isolated CABG on cardiopulmonary bypass. Patients were assigned to two groups: group 1 comprised 147 (18%) patients with newly registered atrial fibrillation (AF) paroxysms; group 2 included 648 (81.3%) patients without cardiac arrhythmia. The preoperative clinical and functional status was assessed using 100 factors. We used statistical analysis methods (Chi-square, Fisher, Mann – Whitney, and univariate logistic regression (LR) tests) and ML tests (multivariate LR and stochastic gradient boosting (SGB)) for data processing and analysis. The models’ accuracy was assessed by three quality metrics: area under the ROC-curve (AUC), sensitivity, and specificity. The cross-validation procedure was performed at least 1000 times on randomly selected data.

Results. The processing and analysis of preoperative patient status indicators using ML methods allowed to identify 10 predictors that were linearly and nonlinearly related to the development of POAF. The most significant predictors were the anteroposterior dimension of the left atrium, tricuspid valve insufficiency, ejection fraction <40%, duration of the P–R interval, and chronic heart failure of functional class III–IV. The accuracy of the best predictive multifactorial model of LR was 0.61 in AUC, 0.49 in specificity, and 0.72 in sensitivity. The values of similar quality metrics for the best model based on SGB were 0.64, 0.6, and 0.68, respectively.

Conclusion. The use of SGB made it possible to verify the nonlinearly related predictors of POAF. The prospects for further research on this problem require the use of modern medical care methods that allow taking into account the individual characteristics of patients when developing predictive models.

Authors: Sazonova N. G. , Makarenko T. A. , Narkevich A. N.
Published: December 2020

Introduction. Endometriosis is a difficult-to-diagnose pathology due to the diversity of clinical manifestations and the lack of high-precision markers necessary for rapid noninvasive diagnosis and timely administration of pathogenetically justified treatment.

The aim of this work was to develop a computer system that allows us to assess the probability of endometriosis with various localizations in women, based on artificial neural networks.

Material and Methods. The neural network mathematical models were constructed and tested based on data from 110 patients with morphologically pre-confirmed endometriosis. Patients were divided into training and test samples. The models were built based on anamnestic data and results of proteomic and enzyme immunoassays in blood plasma samples.

Results and Discussion. In the course of the study, four mathematical models of neural networks were constructed to predict the presence or absence of endometriosis in a woman and its localization if present. Based on these mathematical models, a computer system “Differential diagnosis of endometriosis” was developed. This system allowed to assess the probability and localization of endometriosis in a patient based on parameters obtained as a result of neural network training.

Conclusion. The developed computer diagnostic system allowed predicting the presence of endometriosis and its localization with a probability over 80%, depending on the predicted localization, based on data about the patient and the results of her examination. This system may be used for differential diagnosis of endometriosis from other diseases of the female reproductive system, as well as for differential diagnosis of various endometriosis localizations.
Fuzzy classifiers in cardiovascular disease diagnostics: Review
Authors: Hodashinsky I. A.
Published: December 2020

The complexity of biological objects makes the development of computerized medical systems a difficult algorithmic decision due to the natural uncertainty inherent in these objects. Human thinking is based on vague and approximate data that can be analyzed to form clear decisions. An exact mathematical model of biological objects may not exist in practice, or such a model may be too complex to implement. In this case, fuzzy logic is a suitable tool for solving the specified problem. The problem of medical diagnosis can be viewed as a classification problem. The article presents a literature review of the use of fuzzy classifiers in diagnostics of cardiovascular diseases. The main advantage of fuzzy classifiers in comparison with other artificial intelligence methods is the ability to interpret the resulting classification result. The review aims to expand the knowledge of various researchers working in the field of medical diagnostics.

Introduction. The potential of a new compound in the ongoing drugs discovery process is initially explored using virtual instruments, where its activity is predicted based on its molecular structure.

Aim. This study aimed to evaluate the pharmacokinetic parameters and possible toxicity of isobornyl compounds based on virtual tools.

Material and Methods. Several free Internet resources were used to assess the absorption, distribution, metabolism, excretion (ADME), and toxicity (T) of 2,6-diisobornyl-4-methylphenol (1, Dibornol), 2-hydroxy-3-isobornyl-5-methylbenzaldehyde (2), and 2-((di-n-butylamino) methyl)-6-isobornyl-4-methylphenol (3). Pharmacokinetic properties were calculated on ADMETlab platform. Toxicity and physical properties were evaluated using TEST software based on the structure-property quantification models of organic substances according to structure–property principle. Web server ProTox_II was used for acute toxicity assessment.

Results. Plasma protein binding degrees were 76,9% for (1), 85,9% for (2), and 91,8% for (3). All three compounds were capable of penetrating the blood-brain barrier. Dibornol was identified neither as a substrate nor as an inhibitor of P-glycoprotein unlike (2) and (3). The half-life of all compounds was short (about 2 hours); the clearance was slow (about 2 mL/min*kg). The study showed that (2) and (3) potentially exert the toxic effects during the developmental stage of the organism, while ADMETlab showed potential cardio- and hepatotoxicity for (2) and (3), respectively. All compounds had extremely low solubility in water, which affected the assessments of other indicators by TEST software. The ProTox_II server showed the extremely low toxicity LD50 for all compounds (toxicity class 5).

Introduction. The problem of access to medical care remains extremely relevant in many countries in the world nowadays. In this context, it is advisable to optimize patients’ flow, that is, primary and repeated admissions and appointments for preventive and medical care purposes, and information. The document titled “The Standard for Organizing Outpatient Care in the Tomsk Region” was developed to solve this problem in the region. The document regulates the organizational features of providing medical care to the residents in state polyclinics. The document addresses the following: service parameters, issues of routing patient flows, and the procedures for organizing workplaces and specialists’ behavior.

Objective. To evaluate the effectiveness of the solutions proposed in “the Standard for Organizing Outpatient Care in the Tomsk Region” for routing patient flows in outpatient clinics.

Material and Methods. The effectiveness of measures was evaluated for 35 medical organizations with outpatient departments based on the temporal changes in eight indicators in 2018–2019.

Results and discussion. Except for the percentage of children who passed preventive examination out of the number of children subject to preventive examination, positive dynamics were observed for all study parameters. First of all, this observation suggests the adequacy of proposed solutions from the perspective of the health care system, and secondly, it indicates their acceptance by the patient community. However, the extent of growth/decline is extremely uneven depending on the medical organization, which requires further research.

Conclusion. Standardization of patient flow routing within the state regional health system through the issuance of appropriate orders and further monitoring of their implementation is an effective way to increase the medical care availability.

Published: December 2020

Ülkeler artan enerji talebini karşılamak için geleneksel enerji kaynakları yerine yenilenebilir enerji kaynaklarına yönelmişlerdir. Rüzgar enerjisi bu yenilenebilir enerji kaynakları arasında önemli bir paya sahiptir. Rüzgar enerjisi, sürdürülebilir ve çevre dostu olmasının yanı sıra bazı olumsuz özelliklere de sahiptir. Bu olumsuz özelliklerden en önemlisi rüzgar enerjisinin iklimsel koşullara bağlı olarak anlık artış ve azalışlar göstermesinden kaynaklanmaktadır. Rüzgar Enerjisi Santrali (RES) üretimlerinde de görülen bu değişimler rampa olarak tanımlanmakta ve elektrik şebekelerinin işletiminde büyük problemlere neden olmaktadırlar. Oluşan rampa pozitif yönde (ani bir üretim artışı var) ise rampanın büyüklüğünde diğer tesislerin üretimlerinin azaltılması gerekmektedir. Negatif rampalarda (ani bir üretim azalışı var) ise oluşan enerji açığı büyüklüğünde diğer tesislerin üretimleri arttırılmaktadır. Negatif ve pozitif rampalar elektrik şebekesi işletiminde ek maliyetler oluşturmakta ve güç-frekans dengesine bozucu etki uygulamaktadır. Bu çalışmada öncelikle Türkiye’de işletilmekte olan tüm (161 adet) RES tesislerinin oluşturduğu rampalar istatistiksel olarak incelenmiştir. Daha sonra, bu rampa değerlerini minimize etmek için, RES tesislerinin kurulması gereken illeri belirleyen bir optimizasyon modeli önerilmiştir. Önerilen bu model Genetik Algoritma kullanılarak çözülmüştür. Elde edilen sonuçlar, yüzde rampa değerlerinin oluşturduğu histogram eğrilerinin altında kalan alanlar hesaplanarak değerlendirilmiştir. Bu değerlendirmeler sonucunda, ülkedeki mevcut RES tesislerinin 1. 3 ve 6 saatlik rampa değerlerinin 2017 yılında sırasıyla 16,61, 41,32 ve 59,94olduğu, 2018 yılında ise bu değerlerin sırasıyla 18,10, 40,49ve 63,52olduğu gözlenmiştir. Önerilen optimizasyon yönteminin çözümüyle elde edilen RES yerleşiminde 1,3 ve 6 saatlik yüzde rampa değerlerinin histogram eğrilerinin altında kalan alanların ise sırasıyla 2017 yılında 9,98, 23,65ve 30,97 olduğu, 2018 yıllında ise bu değerlerin sırasıyla 11,01, 25,65 ve 39,14olduğu görülmüştür. Bu çalışmadan elde edilen sonuçlar ülkedeki RES tesislerinin bölgesel dağılımlarının optimize edilerek rampa olaylarının değerlerinin büyük oranda düşürülebileceğini ortaya koymuştur.

Dev motifi tüm dünya anlatılarında olduğu gibi Türk anlatılarında da yaygın olarak yer alır. Bu motif; masal, efsane ve destan gibi çeşitli sahalarda sıklıkla karşımıza çıkar. Ancak devlerin sadece masallarda olduğuna dair genel bir
yanılgı hâkimdir ve“dev”ler ile ilgili çalışmaların büyük çoğunluğu genellikle masallar ve hikâyeler üzerine yapılmıştır. Bu çalışmanın amacı dev motifinin yalnızca masallarda ve hikâyelerde değil destanlarda yer aldığını göstermek,
mitolojik devlerin izlerini (ulaşabildiğimiz örnekler el verdiğince) destanlarda sürmek ve bu anlatılarda karşılaştığımız devlerin genel özelliklerini saptamaktır. Türk destan geleneği içinde yüzlere destan vardır. Tüm destanların
bir makale kapsamında değerlendirilmesinin imkânsız olduğu aşikârdır. Bu nedenle tüm Türk destanlarını değerlendirmek mümkün olmamıştır. Ancak destanlar seçilirken her bir Türk sahasından (mümkün olduğunca) destan seçilerek yelpaze
geniş tutulmaya çalışılmıştır. İncelenen destanlar şunlardır: Basat’ın Tepegöz’ü Öldürdüğü Boy, Saltukname (Oğuz Sahası); Boston, Er-Töştük (Kırgız Sahası); Ural Batır (Bozkurt Sahası); Nart Destanları (Karaçay-Malkar Sahası);
Melike Ayyar (Özbek Sahası); Huyrulukya Hemra (Türkmen Sahası); Kan-Kapçıkay, Alp Manas, Oçı Bala, Kögüdey Kökşin ile Boodoy Koo (Altay Sahası); Cengizname (Türkistan Sahası); Dotan Batır (Kazak Sahası); Er-Sogotox (Yakut Sahası).
Bu Destanlardan yola çıkarak görülmüştür ki Türk destan geleneği dev motifi bakımından masallar kadar olmasa da oldukça zengindir. Destanlardaki devler Türk mitolojisinden izler taşır. Destanlardaki devler kahramanın erginlenmesinde
önemli bir role sahiptir. Fiziksel özellikleri bakımından iri ve genellikle kötü karakterli olup insanlar için tehlike arz etmeleri en belirgin özellikleridir. Dişi devlerin de olması Türk destan geleneğini bir zenginliği olarak
kabul edilebilir.

diğer ayağı Anadolu'da olan bu iki ulu çınarın şiirlerinde aynı ortak paydada buluşması, Türk'ün şanlı mazisini eserlerinde işlemeleri, Türk'ün benliğini ve Türklüğün özünü eserlerinde ortak bir bayrak gibi taşımaları dolayısıyla
şairlerin bu iki şiirini karşılaştırmanın alana katkı sağlayacağı düşünülmüştür. Değerler ve değer eğitiminin günümüzde önemi gittikçe artmaktadır. Milli Eğitim Bakanlığı hazırladığı müfredatlarla ve eserlerle çocuğa değer aktarımına
ayrı bir hassasiyet göstermektedir. Bu yolla çocuğun hem kişiliği şekillenecek hem de bağlı bulunduğu topluma bir aidiyet duygusu geliştirecektir. Milli değerler çocuğa eserler vasıtasıyla öğretilmektedir. Eserlerde atasını, milletini,
vatanını, bayrağını öğrenir. Milli bilince sahip olur ve bu bilinçle hareket eder. Dolayısıyla hem Bahtiyar Vahapzade'nin Tanrı Türk'ü Korusun şiiri hem de O. Y. Serdengeçti'nin Türklüğün İlahisi şiiri, öğrencilerin milli değerlere
ait algılarını geliştirebilecek nitelikte olduğu söylenebilir.

The experiment was consisted of eighteen treatments, laid out in Randomized Complete Block Design and replicated thrice. The results revealed that INM practices increased the plant height over other treatments. Significant increase in yield components like sympodial branches plant-1, number of bolls plant-1 and boll weight were observed under INM treatment and was at par with recommended dose of fertilizers (RDF), Farm yard manure and poultry manure compared to all other treatment combinations. The INM practice resulted in significantly higher seed cotton yield and was comparable with RDF. The quality characters did not exhibit any significant variation among the nutrient management practices. Higher gross and net returns and B:C ratio were also recorded in INM practices.
Evaluation of Ship Profiles in Istanbul Port Region with Two-Stage Clustering Analysis
Authors: BOLAT Firat
Published: December 2020

The increase in industrial production and thus world trade has also increased the significance of the maritime sector further. Ports are of strategic importance as trade points in this sector. Strategies for reducing maritime transport costs and waiting-periods for the ships in ports cause increased competition between ports. Clustering theory focuses on the industries of certain regions defined as industrial zones. Most of the research on the maritime industry focuses primarily on its structure and economic impacts on national economies, without providing detailed information on particular economic and technological activities at the regional level. However, successful clusters are seen as means for regional and national growth. In this context, a two-stage clustering analysis was conducted, considering the different characteristics of the ship profiles that visited the area covering three administrative ports (Ambarlı, Tuzla, İstanbul) of the Istanbul Port Region. The clustering was made according to the type and flags of the ships that visited Istanbul Port Region, the ports they visited and the length of stay in the ports they visited. The clustering characteristics of the Istanbul Port Region were extracted with regard to the ship profiles.

Authors: KILIC Bilal , GÜMÜŞ Ercan
Published: December 2020

Commercial aviation accidents and incidents more prevalent at the certain times of the day. Operational problems (e.g., night vision, flash blindness, black hole illusion, and reflection) faced by pilots while performing nighttime flights pose threats to flight safety. The present paper aims to examine the contributing factors to commercial aviation accidents occurred at night. In this paper, accident reports of 30 commercial airplane crashes occurred over the past five years were analyzed. The contributing factors of those accidents were examined by using HFACS (Human Factors Analysis and Classification System). The relative importance of the causal factors was determined. Literature reviews have indicated that no study has examined the causality of nighttime commercial aircraft accidents by using HFACS as a framework. It was found that physical environment was the most significant causal factor. Skill-based errors were second-highest contributing factors. Perceptual errors and decision errors were ranked as third-highest causal factors. We believe that our results may be useful for reducing the chances of human error and raising safety standards of commercial airline operations.

Published: December 2020

In the present study, the fundamental natural frequencies of curvilinear fiber composite doubly curved panel are optimized. Doubly curved panels are used in various components of the structural frames of the aerospace vehicles. The variable stiffness behavior is obtained by altering the fiber angles continuously according to curvilinear fiber path function in the composite laminates. Structural model is utilized based on the virtual work principle. The aim is to achieve the best fiber paths with maximized fundamental frequencies or in-plane strengths for a composite panels. An eight-layer composite doubly curved panel with two types of boundary conditions are considered as a case study in this research. The boundary conditions include; CCCC, FCFC where C stands for clamped, and F for free edges. Von-Karman kinematic strain relations are used and the first order shear deformation theory (FSDT) is employed to generalize the formulation for the moderately thick doubly curved panel including transverse shear effects. Generalized Differential Quadrature (GDQ) method of solution is employed to solve the governing equations of motion. Numerical results demonstrate the effectiveness fiber angle path and boundary conditions on the natural frequencies of the composite panel. The optimal fiber angle paths of each layer are presented for the above cases in free vibration analysis.

¿Por qué sucedió esto en una sociedad, como la contemporánea, pletórica de ciencia y tecnología?”. El autor de la carta Pandemia, Castaño [1] lanza esta pregunta, una cuestión con todo el sentido del mundo en tanto que lo razonable es que las ciencias nos tendrían que haber conducido al máximo bien, al máximo control de lo “malo” como lo es la pandemia COVID-19. Sin embargo, no ha sido así, y esto requiere de análisis. Efectivamente es inevitable enumerar las consecuencias negativas de esta pandemia, destaco para comenzar la mencionada por el autor en torno a las medidas de confinamiento: “disolviendo así el tejido social, destruyendo la economía y, en última instancia, condenándola a morirse de hambre.

Authors: Mennawi Ahmed Nourrein Ahmed
Published: December 2020

This study aims to investigate the impact of liquidity, credit, and financial leverage risks on the financial performance of Islam banks in Sudan during the period of 2008 - 2018. Panel dataset of 143 observations from (13) banks has been used in this study. Two models of ROA and NPM have been constructed using robust random effects estimates for testing the study hypotheses. The independent variables consist of liquidity and credit risks plus the financial Leverage ratio. Credit risk that measured by nonperformance of loan (financing) and provision of loan (financing) loss ratios; while the liquidity risk measured by cash to deposits ratio, liquid assets to total assets ratio and total loan (financing) to total deposits ratio. The financial performance of Islamic banks in Sudan measured by the ratios of return on assets and net profit margin. The results reveal that the credit risk and financial leverage have significant and negative impact on the financial performance of Islamic banks in Sudan, whereas the liquidity risk generally found to be insignificant. Despite that, the liquidity risk in term of liquid assets to total assets ratio provides a significant and positive influence on the financial performance of Sudanese banks. Finally, the importance of this study is that it touches the most significant types of risks that Sudanese Islamic banks face during their operational cycles.
