Resumo
O avanço do Brasil, com relação aos países desenvolvidos, em pesquisa matemática foi uma herança e, como qualquer outra, nos foi dada pelos nossos primórdios, ou seja, pelos portugueses, quando aqui chegaram. Assim, passou-se por períodos de avanços e retrocessos desde então, buscando se afastar de tal herança para criar uma identidade própria, contudo, ainda hoje a mesma se faz perceptível. Através das lutas na busca por espaços nas políticas de desenvolvimento, por meio dos interesses de uma pequena parte da elite intelectual brasileira, conquistamos a criação de universidades e institutos de pesquisas renomados, que hoje tem o reconhecimento em nível internacional. Com o objetivo de identificar uma conexão entre a pesquisa matemática atual e o desenrolar da história da matemática no Brasil, do período de 1549 a 1934, foi analisado os principais marcos de maior relevancia para evolução da história que consequentemente influenciaram os trabalhos produzidos neste país. A metodologia utilizada neste trabalho foi a de pesquisa descritivo-bibliográfica, de caráter qualitativo. Cloncluiu-se que foi a partir da década de 1930 que se estabeleceu solo fértil para o desenvolvimento intelctual do país, na área da matemática, através da Faculdadede Filosofia, Ciências e Letras. O atual nível de pesquisa em matemática em nossas instituições se deu com a contratação de professores estrangeiros e o desejo, principalmente do Estado São Paulo, de retomar o espaço político e econômico que o país figurava, antes da revolução constitucionalista.

Hepatectomy carried about 20% mortality rate. The most important intraoperative factor is major hemorrhage and hypotension and postoperatively the main reasons are hemorrhage, coagulopathy, renal failure, pulmonary, and cardiac disturbance till biliary fistula and liver failure. Anesthesia and perioperative management have resulted in diminished value of mortality and morbidity at the same time.
Aim: The aim of this study is to submit our experience in anesthesia and perioperative management in liver resection of hepatic metastases in CRC patients.
Material and Methods: In that retrospective study we enrolled 6 patients ASAII- III, from January to July 2019. All patients treated for liver malignancy diagnosis after colorectal carcinoma in elective surgery and received general anesthesia with fentanyl 1-2μg/kg/h, profolol 4.0μg/kg/min via target controlled infusion and vecuronium 0.001mg/kg/min and sevofluran 2%. All patients are monitored with continuous central venous pressure(CVP). We recorded mean artery pressure (MAP), heart rate (HR), CVP, amount of transfusion, incidence of complications and discharge from intensive care and hospital.
Results: Female/male report was 66,6% vs. 33.4%. The ages of patients were 53-72 years with a mean ± SD age of 65.1 ± 9.5 years. CVP was 0-5. Amount of blood was 2.5 unite during intervention. Average of days in intensive care was 3.83. Renal compromised was 3%. Ascites and edema was 50%. All patients were discharged home after 14.66 days.

Published: January 2020

Background: The respect of the needs and wishes of the patients is in the focus of the human health system. The experience of the parents in terms of child’s health care may be used as an indicator of quality of the health care.
Material and methods: The research is a quantitative analytical cross-sectional study. In accordance with the inclusion and exclusion criteria, simple random sample of 207 parents / guardians is covered, whose children in the period of three months, had been hospitalized in the hospital department JZUU Pediatric Surgery Clinic in Skopje.It was used a two parted questionnaire. The first part is a standardized questionnaire (Parent Experience of Pediatric Care - PECP), and the second part concerns the general socio-demographic data of the parent/guardian. Statistical evaluation was performed using appropriate statistical programs (Statistics for Windows 7,0 and SPSS 17.0).
Results: In accordance with the age of the parents, the survey respondents were divided into two groups: a) age ≤ 33 years - 107 (51.69%) and b) age> 33 years - 100 (48.31%).Significant independent predictor of parental satisfaction from the receipt of their child to the clinic research confirms the age of the parent under / over 33 years due to 4.1% of the change in satisfaction (R2 = 0,041). Parents generally believe that their children's room of the clinic is "good", without significant difference between parental satisfaction from both age groups (Mann-Whitney U Test Z = -0,9613 p = 0,3364). Significant independent predictor of parental satisfaction from the room of their child improves the health status after treatment due to 6% of the change in satisfaction (R2 = 0,060). Parents generally believe that testing and treatment of their children in the clinic was "very good" and an independent significant predictor is to improve the health status after the treatment - 7,8% (R2 = 0,078).
Conclusions: Regardless of the generally good parental satisfaction about health care for their children, it is necessary to continuously monitor the status of the clinic in order to consider the possible deficiencies and needs of intervention.

The dynamic expansion of cyber threats poses an urgent need for the development of new methods, methods, and systems for their detection. The subject of the study is the process of ensuring the resilience of computer systems in the presence of cyber threats. The goal is to develop a self-adaptive method for computer systems resilience in the presence of cyberattacks. Results. The article presents a self-adaptive system to ensure the resilience of corporate networks in the presence of botnets’ cyberattacks. Resilience is provided by adaptive network reconfiguration. It is carried out using security scenarios selected based on a cluster analysis of the collected network features inherent cyberattacks. To select the necessary security scenarios, the proposed method uses fuzzy semi-supervised c-means clustering. To detect host-type cyberattacks, information about the hosts’ network activity and reports of host antiviruses are collected. To detect the network type attacks, the monitoring of network activity is carried out, which may indicate the appearance of a cyberattack. According to gathered in the network information concerning possible attacks performed by botnet the measures for the resilient functioning of the network are assumed. To choose the needed scenario for network reconfiguration, the clustering is performed. The result of the clustering is the scenario with the list of the requirement for the reconfiguration of the network parameters, which will assure the network’s resilience in the situation of the botnet’s attacks. As the mean of the security scenario choice, the semi-supervised fuzzy c-means clustering was used. The clustering is performed based on labeled training data. The objects of the clustering are the feature vectors, obtained from a payload of the inbound and outbound traffic and reports of the antiviral tool about possible hosts’ infection. The result of clustering is a degree of membership of the feature vectors to one of the clusters. The membership of feature vector to cluster gives an answer to question what scenario of the network reconfiguration is to be applied in the situation of the botnet’s attack. The system contains the clusters that indicate the normal behavior of the network. The purpose of the method is to select security scenarios following cyberattacks carried out by botnets to mitigate the consequences of attacks and ensure a network functioning resilience. Conclusions. The self-adaptive method for computer systems resilience in the presence of cyberattacks has been developed. Based on the proposed method, a self-adaptive attack detection, and mitigation system has been developed. It demonstrates the ability to ensure the resilient functioning of the network in the presence of botnet cyberattacks at 70 %.
COMPARISON OF ALGORITHMS FOR CONTROLLED PIXEL-BY-PIXEL CLASSIFICATION OF NOISY MULTICHANNEL IMAGES
Authors: Lukin Vladimir , Proskura Galina , Vasilieva Irina 
Published: January 2020

The subject of this study is the pixel-by-pixel controlled classification of multichannel satellite images distorted by additive white Gaussian noise. The paper aim is to study the effectiveness of various methods of image classification in a wide range of signal-to-noise ratios; an F-measure is used as a criterion for recognition efficiency. It is a harmonic mean of accuracy and completeness: accuracy shows how much of the objects identified by the classifier as positive are positive; completeness shows how much of the positive objects were allocated by the classifier. Tasks: generate random valuesof the brightness of the noise components, ensuring their compliance with the accepted probabilistic model; implement the procedures of element-wise controlled classification according to the methods of support vectors, logistic regression, neural network based on a multilayer perceptron for images distorted by noise; evaluate and analyze the results of objects bezel-wise classification of noisy images; investigate the effect of noise variance on classification performance. The following results are obtained. Algorithms of pixel-by-pixel controlled classification are implemented. A comparative analysis of classification efficiency in noisy images is performed. Conclusions are drawn. It is shown that all classifiers provide the best results for classes that mainly correspond to areal objects (Water, Grass) while heterogeneous objects (Urban and, especially, Bushes) are recognized in the worst way; classifiers based on the support vector machine and logistic regression show low recognition accuracy of extended objects, such as a narrow river (that belongs to the wide class of "water"). The presence of noise in the image leads to a significant increase in the number of recognition errors, which mainly appear as isolated points on the selected segments, that is, incorrectly classified pixels. In this case, the best value of the classification quality indicator is achieved using neural networks based on a multilayer perceptron.
THE MATRIX PROCEDURES FOR CALCULATION OF IMPORTANCE MEASURES
Authors: Zaitseva Elena , Sedlacek Peter , Forgac Andrej 
Published: January 2020

System reliability/availability is a complex concept that is evaluated based on numerous indices and measures. There are different methods for the calculation of these indices and measures in reliability analysis. Some of the most used indices are important measures. These measures allow us to evaluate the influence of fixed system components or set of components to the system reliability/availability. Importance measures are used today to allow for various aspects of the impact of system elements on its failure or operability. Analysis of element importance is used in the system design, diagnosis, and optimization. In this paper new algorithms for the calculation, some of the important measures are developed based on the matrix procedures. This paper's goal is the development of a new algorithm to calculate importance measures of the system based on the matrix procedures that can be transformed in the parallel procedures/algorithms. These algorithms are developed based on the application of Logical Differential Calculus of Boolean logic for the important analysis of the system. The application of parallel algorithms in importance analysis allows the evaluation of the system of large dimensions. Importance specific of the proposed matrix procedures for calculation of importance measures is the application of structure-function for the mathematical representation of the investigated system. This function defined the correlation of the system components states and system reliability/ availability. The structure-function, in this case, is defined as a truth vector to be used in the matrix transformation. The truth vector of a Boolean function is a column of the truth table of function if the values of the variables are lexicographically ordered. Therefore, the structure-function of any system can be represented by the truth vector of 2n elements un-ambiguously.
