Authors: ORAL Alihan , ŞAHİN Tolga
Published: December 2019

Giriş ve Amaç: Bu çalışmanın amacı kronik hepatit B’ye bağlı siroz hastalarında, hepatosellüler karsinom gelişimini etkileyen faktörlerin değerlendirilmesidir. Gereç ve Yöntem: Ocak 2010 - Ocak 2019 yılları arasında Demiroğlu Bilim Üniversitesi Tıp Fakültesi gastroenteroloji polikliniğinde hepatit B virüsüne bağlı karaciğer sirozu nedeniyle takip edilen 18 yaş üstü 324 hasta çalışmaya dahil edildi. Olguların demografik (yaş, cinsiyet), beden kitle indeksi, laboratuvar [biyokimyasal ve serolojik parametreler (hepatit B yüzey antijeni, hepatit b virüs-DNA)], görüntüleme ve biyopsi sonuçları hastane bilgi sisteminden retrospektif olarak toplandı. Hastalar hepatosellüler karsinom ve non- hepatosellüler karsinom olarak iki gruba ayrıldı. Bulgular: Çalışmaya dahil edilen hastaların 114’ü hepatosellüler karsinom ve 210’u ise non- hepatosellüler karsinom sirozlu idi. Hastaların yaş ortalaması 54.50±9.30 idi. Hepatosellüler karsinom ile non-hepatosellüler karsinom grupları karşılaştırıldığında yaş ortalaması, Homeostatic Model of Assessment Insulin Resistance, hepatit B virüs-DNA ve alfa fetoprotein değerleri hepatosellüler karsinom grubunda istatistiksel olarak daha yüksek saptandı. Asit, özofagus varis kanaması ve hepatik ensefalopati non-hepatosellüler karsinom grubunda daha yüksek oranda görülürken, spontan bakteriyel peritonit ise hepatosellüler karsinom grubunda istatistiksel olarak daha yüksek oranda bulundu. Hepatosellüler karsinom oluşumunu öngörebilecek bağımsız risk faktörleri incelendiğinde, alfa fetoprotein ve hepatit B virüs-DNA değerlerinin istatistiksel olarak bağımsız risk faktörü olduğu görüldü (sırasıyla; p=0.001 ve p=0.037). Sonuç: Çalışmamızda hepatit B virüsüne bağlı siroz hastalarında hepatosellüler karsinom için alfa fetoprotein ve hepatit B virüs-DNA değerleri bağımsız risk faktörü olarak saptandı. Alfa fetoprotein ve hepatit B virüs-DNA değerleri hepatit B virüsüne bağlı siroz hastalarında hepatosellüler karsinom gelişiminde kullanışlı birer belirteç olabilir.

SEMIPARAMETRIC REGRESSION ESTIMATES BASED ON SOME TRANSFORMATION TECHNIQUES FOR RIGHT-CENSORED DATA
Authors: AYDIN Dursun , YILMAZ Ersin
Published: December 2019

In this paper, we
introduce three different data transformation approaches such as synthetic data
transformation ([1]; [2]; [3]), Kaplan-Meier weights ([4];  [5] ; [6]) and k-nearest neighbour (kNN)
imputation method ([7]) which are commonly used in censored data applications. The
aforementioned approaches are particularly useful when one deals with censored
data. The key idea expressed here is to find the smoothing spline estimates for
the parametric and nonparametric components of a semiparametric regression
model with right-censored data. The estimation is then carried out based on the
modified (or transformed) data set obtained via these transformation
techniques. In order to compare the outcomes of three approaches in
semi-parametric regression setting, we carried out a simulation study.
According to the results of the simulation, it can be said that the Kaplan-Meier
weights have been very successful in dealing with censored observations.

The developed methodology provides a solution to two essential tasks, thereby revealing the gnoseological potential of Big Data technology: social forecasting in the three most significant areas of the information society based on a model which identifies conditions for social resonance; successful implementation of the social dampening procedure based on the use of appropriate management options using multimodal clusterization of social networks based on Big Data technology. The article suggests the tool that helps to increase work efficiency in the sphere of social dampening in the region. The proposed method of regulation may be efficient when it comes to the control of the regional social dampening processes which have variety of forms and broad range of elements and factors, as well as growth dynamics and active transformation of life activities. At the same time using modern products make it possible to evaluate and show changes on a real-time basis which can be useful for local government authorities.

Концепция «Бизнес-модель» vs концепция «Стратегия»: дуализм современных взглядов
Authors: Денисов Игорь Владимирович , Петренко Елена Степановна , Кошмаганбетова Жанар Битимовна , Тогайбева Люсия Исламовна
Published: December 2019

В статье представлено нашло отражение поиска сходств и различий между понятиями «бизнес-модель» и «стратегия». Приводится пример дискуссии о взаимосвязи между бизнес-моделями и стратегией, характеризующейся двумя противоположными подходами. Один из подходов заключается в том, что – бизнес-модель не более, чем новый термин, основанный на исторически сложившихся исследованиях в области стратегии и мало что добавляет к имеющимся знаниям. В статье также отражена противоположная точка зрения на взаимосвязь бизнес-модели и стратегии, суть которой – колоссальное различие между бизнес-моделью и стратегией. Бизнес-модель и стратегия в данном случае – отдельные конструкции, требующие самостоятельного изучения. Кроме того, бизнес-модель рассматривается не только в контексте противостояния двух различных мнений на определение ее сущности, но и в качестве нового представления понятия «стратегия», а также отдельного от «стратегии» научного направления.
Устойчивое развитие, наука, инновации – три вектора региональной экономики будущего
Authors: Исаев Роман Олегович
Published: December 2019

Концепция устойчивого развития («sustainable development») традиционно рассматривается как пересечение социальной, политической и экономической сфер деятельности человека. Однако данный взгляд является достаточно поверхностным и не позволяет увидеть специфику процессов устойчивого развития. В данной работе устойчивое развитие рассматривается в экономическом контексте инновационной деятельности, которая может быть организована в Российской Федерации за счет привлечения прогрессивного методологического инструментария. Автор привлекает работы классических ученых с целью осмысления инновационных процессов в экономике и указывает на две проблемные области: проблему субъекта развития, а также проблему классификации инноваций. В данном исследовании содержательно отражен и схематически представлен новый социотехнический способ решения задач, используемый автором в качестве инновационного метода. В качестве объекта рассматривается «биосферное партнерство» как потенциальная единица инновационной экономики региона.

Published: December 2019

Exocyclic adducts of DNA bases, such as etheno- and hydroxyalkano- ones, are generated by a variety of bifunctional agents, including endogenously formed products of lipid peroxidation. In this work we selectively modified cytosines in the 5'-d(TTT TTT CTT TTT CTT TTT CTT TTT T)-3' oligonucleotide using: chloroacetaldehyde to obtain 3,N(4)-alpha-hydroxyethano- (HEC) and 3,N(4)-etheno- (epsilonC), acrolein to obtain 3,N(4)-alpha-hydroxypropano- (HPC) and crotonaldehyde to obtain 3,N(4)-alpha-hydroxy-gamma-methylpropano- (mHPC) adducts of cytosine. The studied adducts are alkali-labile which results in oligonucleotide strain breaks at the sites of modification upon strong base treatment. The oligonucleotides carrying adducted cytosines were studied as substrates of Escherichia coli Mug, human TDG and fission yeast Thp1p glycosylases. All the adducts studied are excised by bacterial Mug although with various efficiency: epsilonC >HEC >HPC >mHPC. The yeast enzyme excises efficiently epsilonC>HEC>HPC, whereas the human enzyme excises only epsilonC. The pH-dependence curves of excision of eC, HEC and HPC by Mug are bell shaped and the most efficient excision of adducts occurs within the pH range of 8.6-9.6. The observed increase of excision of HEC and HPC above pH 7.2 can be explained by deprotonation of these adducts, which are high pK(a) compounds and exist in a protonated form at neutrality. On the other hand, since epsilonC is in a neutral form in the pH range studied, we postulate an involvement of an additional catalytic factor. We hypothesize that the enzyme structure undergoes a pH-induced rearrangement allowing the participation of Lys68 of Mug in catalysis via a hydrogen bond interaction of its epsilon-amino group with N(4) of the cytosine exocyclic adducts.
An approach for image Contrast and Resolution Enhancement based Wavelet Transform by incorporating Cuckoo Search and SVD algorithms
Authors: S Sandeepa K , Jagadale Basavaraj N , Bhat J S
Published: December 2019

Image enhancement techniques are prominently used to analyze the image by enhancing key factors like contrast, resolution, and quality of the image. With the proper analysis of images, it is desirable to pre-process the image for resolution and contrast enhancement. We present here a new approach based on discrete wavelet transform (DWT), singular value decomposition (SVD) for image contrast and resolution enhancement, The contrast of the image is enhanced by maximum value fusion technique applied to the images created by using modified cuckoo search algorithm (CSA) and singular value decomposition separately. The masking approach is employed, for obtaining residual pixel value between original and scaled images independently. The resolution of the image is enhanced by combining interpolated high-frequency sub-band and maximum value fusion images. The proposed algorithm helps to minimize the noise artifacts and over enhancement problems. Experimental results are tested in terms of peak signal to noise ratio (PSNR) and absolute mean brightness error (AMBE). The proposed method shows better performance compared to other contrast and resolution enhancement techniques.
Modification of KNN Algorithm
Authors: Pandey Shubham , Sharma Vivek , Agrawal Garima
Published: December 2019

K-Nearest Neighbor (KNN) classification is one of the most fundamental and simple classification methods. It is among the most frequently used classification algorithm in the case when there is little or no prior knowledge about the distribution of the data. In this paper a modification is taken to improve the performance of KNN. The main idea of KNN is to use a set of robust neighbors in the training data. This modified KNN proposed in this paper is better from traditional KNN in both terms: robustness and performance. Inspired from the traditional KNN algorithm, the main idea is to classify an input query according to the most frequent tag in set of neighbor tags with the say of the tag closest to the new tuple being the highest. Proposed Modified KNN can be considered a kind of weighted KNN so that the query label is approximated by weighting the neighbors of the query. The procedure computes the frequencies of the same labeled neighbors to the total number of neighbors with value associated with each label multiplied by a factor which is inversely proportional to  the distance between new tuple and neighbours. The proposed method is evaluated on a variety of several standard UCI data sets. Experiments show the significant improvement in the performance of KNN method.
An Analysis of the Influence of the Linear Hydraulic Drive Regulation Law on the Energy and Dynamic Characteristics of a Single-Stage Compressor Unit
Authors: Yusha V.L. , Busarov S.S. , Nedovenchanyi A.V. , Silkov M.V.
Published: December 2019

The significant unevenness of the instantaneous power of a piston compressor unit during its operating cycle creates certain problems in the selection and operation of drive engines, which are usually solved by installing a flywheel. In single-stage compressor units with linear drive based on low-speed long-stroke stages, the amplitude change in the gas force during the operating cycle is significantly higher compared to similar compressor units. This leads to such an increase in the amplitude change of the instantaneous power of the drive, that the use of a flywheel becomes impractical. The article discusses the issues of ensuring the required dynamic and energy characteristics of single-stage compressor units with linear hydraulic drive by synthesizing the law of motion of the drive, the piston of which is rigidly connected to the piston of the compressor stage. Design methodology and the results of the computational parametric analysis are presented. The relevance of determining effective laws of motion of the drive as applied to compressor units with linear actuators based on low-speed long-stroke stages is confirmed.
Motion Control of Electric Propulsion Spacecraft Transfers between the Libration Points L1 and L2 of the Earth–Moon System
Authors: Fain M.K. , Starinova O.L.
Published: December 2019

This article presents a study of nonlinear motion of an electric propulsion spacecraft. Spacecraft transfers between the libration points L1 and L2 of the Earth-Moon system are analyzed. The influence of the shaded areas and gravitational effects of the Earth, the Moon and the Sun is taken into account. The mathematical model of the transfers is described within the barycentric coordinate frame. The exact optimal solution of the problem is obtained using Pontryagin’s maximum principle formalism and the numerical solution of the boundary value problem. The method of optimizing the parameters and controls of interplanetary trajectories of the spacecraft based on the optimization of dynamic system components and on Fedorenko’s method of sequential linearization is applied in this study. This method allows limitations on composite functions with Fréchet derivatives. As the results of the simulation, the control laws and corresponding trajectories are obtained.
Methods of Creating Functional Models of Gas Turbine Engine Parts by Means of Numerical Modeling and Machine Learning Algorithms Using a Turbine Disk as an Example
Authors: Reznik S.V. , Sapronov D.V. , Vasilyev B.E. , Semenov A.V.
Published: December 2019

Each aircraft gas turbine engine has design, layout and technological features that affect its operational life. To take into account all the factors that affect the operational life of the engine, a large amount of calculations is required. In this regard, it is important to develop functional models that represent virtual images of the main parts of each engine and contain information about their geometry, loading parameters and characteristics. These models should express the relationship between the many parameters measured and calculated during flight with the calculated values of the cyclic durability of the main engine parts. In recent years, machine learning has been used to solve such problems. The essence of this method is in training in the process of analyzing a variety of solutions under different parameters. This paper presents an approach that allows creating functional models of gas turbine engine elements using numerical modeling of the heat-stressed state and machine learning algorithms.
MOOD AND MODALITY IN SOEKARNO’S 1955 SPEECH
Authors: Syamsidar Syamsidar , Yatmikasari Ika , Nurrachman Dian
Published: December 2019

This research deals with the interpersonal meaning of Soekarno’s speech in the first 1955 Asian-African Conference. The study focuses on analysing mood types and choice of modality in that speech. As the speech brought the theme of spirit of solidarity and brotherhood, then this study aims at examining how the choice of mood types and modality represent this theme. To realize this, the framework of Systemic Functional Linguistic (SFL), particularly on mood and modality system by Halliday and Mathiessen (2004), is employed. From the discussion, it is found that clauses are mostly categorized as declarative clauses. It proves that the Asian-African Conference was held by the realization of solidarity and brotherhood. The use of declarative clauses indicates the speaker’s competences in delivering persuasive speeches by conveying factual information. In addition, it is found that the speaker is neutral and seems to have close relation with the audience. Meanwhile, the use of low degree of modality is helpful to encourage the audience’s confidence to act together.

Poetas en la frontera de México-Estados Unidos de América: Heriberto Yépez y Esther M. García
Authors: Ballester Pardo Ignacio
Published: December 2019

La poesía mexicana se caracteriza en los últimos años por la descentralización de algunas prácticas literarias que tienen que ver con el conflicto producido en la frontera de México-eua. Desde la obra de Heriberto Yépez, Por una poética antes del paleolítico y después de la propaganda (2000), hasta Esther M. García, con Mamá es un animal negro que va de largo por las alcobas blancas (2017), podemos estudiar la fisión, la violencia, especialmente a las mujeres, la “telefísica” y el humor para criticar los límites que se cruzan entre múltiples poéticas y órganos de poder. En contacto con San Diego (California) y El Paso (Texas), la lírica que se ha publicado en las décadas recientes permite entender los problemas transfronterizos más allá de la convención.

Published: December 2019

Christian education aims to enable students to take part in serving God and others both now and forever. The barriers to learning mathematics make it difficult for students to achieve the goals of Christian education. In some cases, students are found to have barriers to learning mathematics. Based on this problem, the researchers wanted to know the types of barriers to learning mathematics, the causes, and the responses of teachers, schools, and students to these barriers. This study used the case study method of a qualitative approach and the subjects were grade 8 students. The data collection techniques used were interviews for mathematics teachers and principals as well as open-ended questionnaires for students. The results revealed that there were barriers to learning mathematics that can be categorized into internal and external factors including a lack of learning willingness on the part of the students, inappropriate views of mathematics, uncontrolled classroom conditions, and the contagion of the environment. The responses given by teachers, schools, and students about mathematics learning barriers include reviewing, giving additional lessons, and relearning either individually or through others. Suggestions for teachers and principals are to organize workshops related to mathematics learning barriers and improving teaching quality.

Retalho Livre Anterolateral da Coxa para Tratamento de Quelóide Esternal
Authors: Guedes Tiago , Coelho Gustavo , Guimarães João , Costa Horácio
Published: December 2019

As cicatrizes hipertróficas e quelóides representam distúrbios cicatriciais hiperproliferativos que podem ter um impacto significativo na vida dos doentes. Os autores apresentam o caso de um doente de 53 anos, com uma cicatriz quelóide na região esternal após exérese de quisto sebáceo e múltiplas sessões de infiltração de corticóide, com um agravamento marcado da lesão. O doente foi submetido a exérese do quelóide e reconstrução do defeito com retalho livre fasciocutâneo anterolateral da coxa (anterolateral thigh flap – ALT). O pós-operatório imediato e tardio decorreu sem intercorrências, sem sinais de recidiva. O tratamento de quelóides esternais passa, inevitavelmente, por diminuir a tensão na região operada, de forma a evitar a recidiva e eventual agravamento da lesão. O tratamento deste tipo de cicatrizes é complexo, tornando-se um verdadeiro desafio para o cirurgião plástico. No caso clínico apresentado, dadas as dimensões e localização da cicatriz, a sua excisão provocou um defeito extenso, sendo necessária a transferência microcirúrgica de tecidos para cobertura completa, minimizando a tensão na região esternal.

Published: December 2019

Background: Delays of inpatient transfer from the Emergency Department (ED) will affect delayed care, overcrowd at ED, and patient’s disappointment. Such patient transfer delay from the Emergency Departement (ED) also occurs at Haji General Hospital, Surabaya.Aims: This study analyzed the relationship  between inpatient boarding time from Emergency Departement (ED) and patient satisfaction at Haji General Hospital, Surabaya.Methods: This was an observational research using a cross-sectional approach. The population was 980 ED patients who decided to be hospitalized. Out of 980 ED patients, the study only involved 83 respondents selected by simple random sampling. The instruments used were observational sheet and questionnaires to collect data which were then analyzed with a chi-square test.Results: Average boarding time was 142 minutes 25 seconds (minimum = 60 minutes; maximum = 290 minutes). Almost all respondents (81.3%) were satisfied about fast boarding time. Inpatient boarding time at the Emergency Departement (ED) was significantly related to patient satisfaction (p = 0.058 <α = 0.1). The faster inpatients move to ED, the more satisfied they are.Conclusion: The average patient boarding time from the Emergency Departement (ED) to Inpatient Unit was slow. Respondents were satisfied with the quality of services even though patient boarding time was slow.

Authors: Arroyo Margarete , Chiarini Caio , Yamaoka Denise
Published: December 2019

O objetivo deste artigo é discutir as implicações para o campo da educação musical de duas pesquisas que estabeleceram diálogos entre esse campo e políticas públicas voltadas a adolescentes: uma para proteção social básica e outra para medidas socioeducativas. Ambas foram realizadas na cidade de São Paulo, em instituições responsáveis por colocar em ação essas políticas, respectivamente, os Centros para Crianças e Adolescentes e a Fundação Casa. As investigações são do tipo qualitativo, estudos de casos múltiplos, uma focalizando a razão de as práticas musicais com adolescentes estarem em contextos de proteção social básica, e outra centrada na construção, pelos educadores musicais, de suas ações pedagógico-musicais em cenário de medidas socioeducativas voltadas a adolescentes em conflito com a lei. A discussão proposta neste artigo volta-se para a presença da educação musical em dois cenários que compartilham aspectos comuns, regidos por políticas públicas que contextualizam as práticas musicais neles realizadas. Juntar esses dois estudos em um mesmo texto também decorre do interesse em colocar lado a lado práticas musicais envolvidas em dois ambientes de infeliz relação: um que visa evitar que meninas e meninos adolescentes, vítimas das injustiças sociais no Brasil, cheguem à situação extrema de serem considerados infratores, condição no segundo cenário, e, aí, tenham sua liberdade cerceada. Como implicações desses diálogos entre educação musical e políticas públicas estão a relevância de situar práticas musicais no âmbito macropolítico, visando a uma maior consciência do papel delas nos cenários, bem como nas atuações de educadores musicais.
