Published: November 2018

A measuring and evaluating of quality are critical factors that are responsible for customer satisfaction. This article deals with the issue of measuring and evaluating of processes’ performance in the quality management of Slovak wood-processing enterprises. A questionnaire method was used at the primary level of information gathering. The questionnaire targeted 300 most significant Slovak wood-processing enterprises. It was found out that the most common methods of measuring and evaluating of processes’ performance in the quality management of Slovak wood-processing enterprises are universal indicators of process performance, indicators for measurement of production and non-production processes and benchmarking. Conversely, the least used methods are EFQM, Six Sigma and process controlling of quality. Based on the analysis of primary and secondary sources, a model for measuring and evaluating of processes’ performance in the quality management system for small and medium enterprises as for large wood-processing enterprises was proposed.

Published: November 2018

AbstractThe security of the web is a very important issue, because every day we make a variety of operations in it, for different reasons, during the day. Apart from protecting the information, contacts, accounts and data on the web, such data should be inaccessible to third-party persons. This in turn depends on the success of the authentication process performed on the individual web. With authentication, it is possible for users to protect their information and make their transactions only for themselves. However, the authentication mechanism used at this point must have a high level of safety. With the purpose to damage a person's privacy and access account information and gain profit in this way, many malicious persons have developed various methods of attacks to bypass authentication mechanisms. These methods sometimes succeed on a variety of authentication mechanisms, and put users and relevant websites into a difficult situation, and may even damage them in a variety of aspects. In order to protect personal information on the web system and provide the security of transactions carried out at a high level, in this study, we propose a two-factor authentication mechanism based on facial recognition. Besides, we discuss some implementation details about the proposed method. The proposed method aims to bring a new approach to the authentication system to perform our online process with the highest security. In addition to the standard authentication systems, using face recognition as a secondary level of security will contribute to the emergence of a new authentication mechanism.

Social media has been widely used in our daily lives, which, in essence, can be considered as a magic box, providing great insights about world trend topics. It is a fact that inferences gained from social media platforms such as Twitter, Faceboook or etc. can be employed in a variety of different fields. Computer science technologies involving data mining, natural language processing (NLP), text mining and machine learning are recently utilized for social media analysis. A comprehensive analysis of social web can discover the trends of the public on any field. For instance, it may help to understand political tendencies, cultural or global believes etc. Twitter is one of the most dominant and popular social media tools, which also provides huge amount of data. Accordingly, this study proposes a new methodology, employing Twitter data, to infer some meaningful information to remarks prominent trend topics successfully. Experimental results verify the feasibility of the proposed approach.

Authors: Amiar Adel , Adjabi Mohamed
Published: November 2018

Flexible alternating current transmission systems are used since nearly four decades and present very good dynamic performances. The purpose of this work is to study the behaviour of a system where static compensator (STATCOM) is located at the midpoint of a long transmission line functioning in disturbed modes with various levels of load caused by tripping and then, reclosing of the incoming station breaker. The studied model and starting from the analysis of various alternatives will lead to the checking of the aptitude of the STATCOM to maintain the voltage plan and to improve the power flow in electroenergetic system which is the east region of Algerian 400 kV transmission network. The steady state performance of STATCOM’s controller is analysed through computer simulations with MATLAB/Simulink program. The simulation results have demonstrated that STATCOM can be effectively applied in power transmission systems to solve the problems of poor dynamic performance and voltage regulation.

Comparing Rule-Based Translation to Syntax Tree Diagram Translation
Authors: Heryono Heri
Published: November 2018

Machine translation has developed more effectively to be specified as modern linguistics characterization. It indicates the formalization of translating process by machine within humanly approaching. Recently, in order to help people communicate indirectly through written, machine translation has its own system to break and match the codes through comprehensive database of words pocket. In linguistics perspective, machine translation always be assisted by its definite performance through derivative computational system. The problem appears when users need to translate ambiguous sentence from English to Bahasa Indonesia or vice versa. The paper used rule-based system which contains particular parts in order to run the process of translating; starts from tokenization, pre-processing, reordering and morphological process which lead to output accuracy. And used syntactic diagram translation, which was carried out manually by generating sentences into small units. The result of this research showed that RBS runs by standard linguistics system; and the output of translating refer to basic translation without giving any alternative translation nor meaning. While using syntactic diagram, there are possibility to get alternative result not only by linguistics features but also based on signification meaning of both translations. Those techniques run by considering linguistics features in order to help users to get translation output better.
Creating Personas for Political and Social Consciousness in HCI Design
Authors: Wilson Anna , De Paoli Stefano , Forbes Paula , Sachy Marco
Published: November 2018

Personas have become an important tool for Human-Computer Interaction professionals. However, they are not immune to limits and critique, including stereotyping. We suggest that while some of the criticisms to personas are important, the use of personas is open to them in part because of an unquestioned focus on explicating user needs and goals.
Traditionally indeed, personas and the associated scenarios are created by focusing on needs and goals of the target users. This focus, while helping designers, also obscures some other potentially relevant aspects. In particular, when the goal of the product or software being designed is associated with social and political goals rather than with bringing a product to the market, it may be relevant to focus personas on political aspirations, social values and the will of personas to take action. We argue that it would be possible when producing personas (and associated scenarios too) to partially move away from representing needs and embrace personas which more explicitly represent political or social beliefs. We suggest that drawing on phenomenography will allow to achieve this. We provide empirical evidence for our position from two large-scale European projects, the first one in the area of Social Innovation and the second in the area of eParticipation.
“Un Geste Suffit”? Unpacking the Inconvenient Truths about Al Gore’s Celebrity Activism
Authors: Marshall David , D'Cruz Glenn , Mcdonald Sharyn
Published: November 2018

The present work interrogates Al Gore’s persona as a climate change activist with reference to a process we describe with the neologism “personafication”: the act of constructing/presenting a public persona in order to cultivate impressions that enable public figures to consolidate authoritative reputations. The formation of such a commanding persona requires the circulation of three forms of symbolic capital: cultural, celebrity, and reputational capital as well as the performance of overtly theatrical strategies calculated to establish an empathetic relationship between performer and audience. In 2006, former Vice President Al Gore released the award-winning documentary, An Inconvenient Truth. This film subsequently functioned as a catalyst for various forms of climate change activism. This paper unpacks the contradictory ideological and cultural work performed by the film with reference to what we describe as un geste suffit; that is, those gestures that merely perform individual agency in order to connect the formulation of personal ethical identity to communal forms of political activism like environmentalism. Through a close reading of the presentation of Gore’s persona in the film itself, and research which tracks the reception and political efficacy of the film, the paper contributes to the growing body of scholarship on the politics of environmental/scientific communication. Finally, we locate our reading of Gore’s film within a contemporary context by making reference to the way An Inconvenient Truth is both resistant to and complicit with the environmental policies of the Trump administration.

Published: November 2018

Modern complicated ecological conditions cause a general necessity in improving the food structure of the population due to improving the quality, biological value and taste characteristics of products. Just that is why, the aim of the work was to study the influence of milk thistle shot on quality parameters of the sour-milk beverage – kefir. It was established, that it had the homogenous consistence with a broken clot and color from white to creamy with shot particles. The increase of the milk thistle shot dose to 3 % and 4 % results in the taste with the brightly expressed milk thistle smack and brown color with the expressed milk thistle content. The viscosity of kefir with fms 2,5 % changes during seven days of storage, although remains rather high at 8 day, namely 47 s. The increase of the viscosity of kefir with milk thistle shot is explained by its hygroscopic properties, in which result free moisture of the product is bound. The analysis of microbiological parameters in the process of storage of kefir with milk thistle shot allows to make a conclusion about the satisfactory sanitary condition of the new product and its harmlessness for consumer’s health. In the kefir with milk thistle shot the general amount of amino acids grew by 11,6 %, including irreplaceable ones – by 10,1 %, replaceable – by 12,6 %, that indicates its biological value.

Addition of milk thistle shot to kefir didn’t cause changes of the biological value of the protein component of the combined product. It is testified by the mean value of amino acid scores of control (129,3 %) and experimental (127,9 %) samples of kefir. Some growth of the valine score (3,6 %) can be noted.

So, the combined product is characterized by the balanced amino acid composition. Due to adding milk thistle shot, consumption of amino acids, necessary for synthesis of proteins and essential number of compounds, vitally important for the human organism, grew.
HYPOMETHYLATING AGENTS IN TREATMENT OF MYELODYSPLASTIC SYNDROME
Authors: Boyko Olha
Published: November 2018

Thelkey to the successful treatment of myelodysplastic syndrome is the careful characterization and diagnosis of the disease, which includes clinical, cytogenetic, biological and molecular investigation of individual patients. Today therapeutic approaches to the treatment of such patients are differentiated and depend, first of all, on the subtype of the disease, age, general condition of the patients and the possibility of allogeneic hematopoietic cell transplantation. For young patients, the best option is transplantation, whereas in older patients, the standard of therapy is the use of hypomethylating agents (azacitidine, decitabine). These drugs promote hematologic improvement, elimination of transfusion dependence and prolongation of the duration of both general and leukemia free survival in elderly patients with concomitant pathology.

Despite the fact that therapy with hypomethylating drugs is widely used and has good results, many respondents are losing their response within 1–2 years. Reasons for the development of resistance to this type of treatment are still unclear, and the insensitivity to drugs is associated with very poor prognosis in patients with all subtypes of myelodysplastic syndrome. Such data and the presence of numerous genetic and epigenetic mechanisms for the development of this pathology have prompted the use of combinations of drugs with different application points and are relevant in terms of research. In the literature review, the results of clinical studies on the use of hypomethylating agents in patients with MDS of low and high risk, as in monotherapy and combined schemes are presented.

The nearest prospect of treatment of myelodysplastic syndrome is the creation of new treatment regimens based on a combination of drugs of different pathogenetic direction for the elimination of the dysplastic clone in order to achieve not only long-term remissions, but also lengthening the duration of overall survival, especially for patients with high risk myelodysplastic syndrome.

Authors: Feyta Yuliya , Pyrohova Vira
Published: November 2018

Postpartum purulent-septic complications (PPSC) and their problems are most urgent for modern obstetrics due to their significant frequency. Maternal sepsis is one of the leading causes of maternal mortality around the world, accounting for about one-tenth of the global number of maternal deaths. Understanding the risk factors for the development of septic complications of puerperium is important for preventive strategies.

Aim. To study the possibility of forming high-risk groups on the basis of analysis of anamnestic data and the course of puerperium in women with PPSC as part of the preventive measures for the development of such complications.

Materials and methods. The first stage of the study involves a retrospective analysis for the allocation of risk factors for the development of PPSC in women, who underwent inpatient treatment for this pathology - main group (n=108); сontrol group (n=35) – parous with uncomplicated flow of the postpartum period. Prospective research enrolled 65 pregnant women with extragenital pathology and/or complicated pregnancy (group 1); 30 pregnant women without severe concomitant somatic pathology with physiological course of pregnancy (group 2). The following were taken into account: age, obstetrical and gynecological history, extragenital pathology, laboratory diagnostic data. Differences in mean values were considered significant with a probability level of at least 95 % (p<0.05).

Results. To the risk factors for the development of PPSC, we classified as follows: gynecological diseases in history: menstrual dysfunction, chronic inflammatory diseases of the genital organs, bacterial vaginosis; complications of pregnancy and labor: preeclampsia, preterm labor, premature rupture of membranes, long anhydrous span, chorioamnionitis, weakness of labor, genital tract ruptures, placental attachment pathology, operative vaginal birth, bleeding; concomitant extragenital pathology: diabetes, obesity, diseases of the urinary system, diseases of the cardiovascular system, respiratory diseases, varicose disease, anemia.

Conclusions. The connection between the presence of concomitant somatic pathology, the complicated course of pregnancy and labor and the subsequent development of septic complications in the postpartum period have been established. Prediction of the risk of their occurrence at the stage of pregraviditic preparation, with various complications of pregnancy and childbirth, especially in women with extragenital pathology, differential prevention will reduce the frequency of PPSC.

Authors: Markin Andriy , Dubey Leonid
Published: November 2018

Background: Today psychometric characteristics of Ukrainian version of the questionnaire Haemo-QoL remain researched insufficiently. This publication describes the procedure and results of the test-retest reliability of this questionnaire in children with hemophilia A.

Objectives: Study the test-retest reliability of the Ukrainian version of the Haemo-QoL questionnaire for assessing the health-related quality of life (HRQoL) in children with hemophilia A, and determine the possibility of its use in practical and theoretical medicine in terms of time reliability.

Methods. The quality of life assessment (QoLA) was performed using the correspondence method, by interviewing 32 children with hemophilia A (self-report) and 32 parents of the children (proxy-report). The questioning was conducted twice at intervals of 4–6 weeks (primary test and re-test). The Haemo-QoL questionnaire version of age group I (4–7 years old), II (8–12 years old) or age group III (13–16 years) was used to measure the quality of life in children with hemophilia; and three versions were used for parents of children of corresponding age groups. These interviews were analyzed, the correlation between the data of primary test and re-test was determined using Spearman's rho, Pearson correlation coefficients, Wilcoxon’s W criterion, Cohen's d effect size was determined for separate comparisons.

Results: HRQoL indices are not statistically different between tests on all scales (p>0.05), except for the “Family” and “Others” scales (p<0.05). Total HRQoL is statistically different (p=0.0013), however, with a median difference of 0.25 only and an average absolute difference variability of 1.67±1.51 (5.42±2.83 %). Total HRQoL in parent versions did not change statistically, unlike the children’s versions, but the difference between the tests was only 1.32 and Cohen’s d ES - 0.08. For versions Ip, IIp, IIIc/p there was no statistical difference, the versions Ic and II statistically differed (p=0.038; t=–2.39 and p=0.0022; t=–3.98, respectively) with a mean difference of 2.0 and 1.6, respectively.

Conclusion: The Ukrainian version of the Haemo-QoL questionnaire has sufficient test-retest reliability for quantitative dynamic reflection HRQoL in patients with hemophilia A.

Published: November 2018

In recent years, breast cancer (BC) is the most common cancer pathology and the most common cause of disability among women in developed countries. Finding the most effective ways of interaction between the patient and the doctor creates the preconditions for the necessary analysis of the treatment process from an objective and subjective point of view. Therefore, an important indicator to be taken into account is the quality of life of a patient.

To compare the indicators of a comprehensive assessment of the quality of life of patients to the adverse locally advanced forms (LA) of breast cancer before and after systemic intravenous polychemotherapy (SPCTx) and selective endolymphatic polychemotherapy (ELPCTx) in neoadjuvant mode.

The study was conducted on the basis of a random analysis of outpatient cards from 112 patients with LA BC T4A-DN0-3M0 who received a comprehensive antitumor treatment on the basis of the Donetsk regional antitumor center and the University Clinic of the Odessa National Medical University from 2000 to 2017, which was proposed a questionnaire at various stages of preoperative treatment. The first (control) group consisted of 65 patients (58 %) with inoperable forms of LA BC, which was performed in neoadjuvant mode by SPCTx. The second (study group) included 47 patients (42 %) with inoperable forms of LA BC, which was performed as a neoadjuvant course ELPCTx.

According to the integral indicators of quality of life and quality of health between patients in the control and study groups, there was no statistically significant difference. In a detailed analysis of the indicators of symptomatic scales, the difference between the groups did not exceed the critical. Based on the results of a study conducted among patients receiving endolymphatic chemotherapy in a neoadjuvant mode, the subjective evaluations of treatment in absolute numbers have better reference values without statistical superiority.

The study of the integrative indicator of quality of life and its discrete elements is an ergonomic and economical means of heuristic assessment of the health of patients in order to further develop more rational and convenient ways of solving urgent issues of modern oncology by increasing compliance and finding a compromise between the physician and the patient.
PROGNOSTIC VALUE OF KIDNEY FUNCTION PARAMETERS IN PATIENTS WITH CHRONIC HEART FAILURE AND LEFT VENTRICULAR REDUCED EJECTION FRACTION
Authors: Dudnik Anna , Liashenko Alina , Voronkov Leonid
Published: November 2018

Chronic heart failure (CHF) is a complex clinical syndrome characterized by progressive course, unsatisfactory quality of life, poor prognosis and high incidence of concomitant renal dysfunction (RD).

The aim of our work was to study the prognostic value of a number of renal function indicators in patients with CHF and a reduced left ventricular ejection fraction (LVEF).

Materials and methods. 134 patients with stable CHF and reduced (<40 %) LVEF, II-IVNYHA class were examined. Patients were divided into two groups according to the level of GFR: the first group of GFR<60 ml/min./1.73 m², the second – GFR≥60 ml/min./1.73 m². The average follow-up period was 13.4 months, the maximum was 27.5 months.

Results. In 53 patients RD was detected (glomerular filtration rate was ˂60 ml/min/1.73 m²), which was 39.5 %. Patients of both groups did not differ in their main hemodynamic parameters, left ventricular ejection fraction, and pharmacotherapy structure, but were older in age and heavier clinically. After the analysis of survival curves of patients depending on GFR, a group of patients with RD had a significantly worse survival prognosis compared to a group without RD. After adjusting the groups by age and NYHA class, the indicated difference was maintained. The subjects were divided according to median levels: blood urea nitrogen, blood urea nitrogen / creatinine ratio, microalbuminuria, albumin / creatinine ratio in urine.

The long-term survival of the formed groups was analyzed. The level of blood urea nitrogen did not significantly influence the prognosis of patients with CHF and reduced LVEF. At the same time, when the groups were divided, depending on the median value of the blood urea nitrogen / creatinine ratio, there was a significantly higher risk of fatal outcome in the group with lower indices. The level of MAU did not significantly affect the survival of patients. In addition, a comparison of the survival of patients with higher and lower values of the albumin / creatinine ratio in the urine revealed a significantly higher risk of death in patients with higher values.

Conclusions:

1. The presence of RD (GFR˂60 ml/min/1.73 m²) is observed in 39.5 % of patients with CHF and reduced LVEF and is associated with their worst long-term survival.

2. The BUN and MAU do not have sufficient predictive information about the forecast of long-term survival of the above category of patients.

3. At the same time, the values of the BUN/ Сreatinine ratio ˂24.5 and the ACR ˃12.7 indicate patients with CHF who have a higher long-term risk of death.

The work is devoted to improving technologies of enriching food raw materials and products. The object of the research is dough semi-products of leavened, puff and unleavened dough, enriched with a dietary supplement, based on the chelate complex. The conducted studies are directed on investigating the evenness of distribution of microelements in the volume of dough semi-products and establishing the influence of a supplement on functional-technological properties of these semi-products. At that there were used methods of nuclear magnetic resonance, electronic paramagnetic resonance, low-temperature calorimetric method and rheological research methods. The method of nuclear magnetic resonance established that a dietary supplement, based on the chelate complex influences the mobility and interaction of water molecules with an environment in dough semi-products. The method of electronic paramagnetic resonance proved the evenness of distribution of a microelement of a dietary supplement by the volume of studied dough semi-product. Rheological and low-temperature calorimetric methods established that an introduced supplement favors a change of the qualitative and quantitative composition of system water of studied semi-products and changes their elastic properties. The obtained results proved the efficiency of using a powder-like supplement with stabilized chelates of metals in technologies of enriching food products.
FORMATION OF TECHNOLOGICAL INDICES OF DRY POWDER OF CABBAGE

Published: November 2018

One of the resource-saving methods of drying, from the point of view of preserving food and biological value, providing the appropriate recovery properties of dried food products (DFP) and energy intensity of the process, is drying with mixed heat supply (MHS drying).

The scientific concept of work on the formation of a universal and DFP stable functional and technological potential is formulated, which is the basis for modeling and designing the formulation composition and technology of food products by groups and types with its use or interchangeability.

As the subject of research for the formation of quality indicators of cereals, white cabbage is selected, as it is a typical vegetable for Ukraine and accordingly has a high degree of assimilation of natural micronutrients in the human body.

Structural studies have shown the predominantly crystalline structure of polysaccharides, that is, less than their transformation under conditions of MHS drying, as compared with convective conditions.

The effect of MHS drying on the formation of DFP quality indicators is determined by the method of recording IR spectra with Fourier transform. For studies of the violation of total internal reflection, it has been established that the process of DFP reduction leads to an increase in the availability of organic substances in the solvent, which will facilitate the extraction of extractives in the recovery of raw materials.

It is established by the number of aroma, the more aromatic-forming substances are contained in the MHS drying samples irrespective of the process temperature, less in the dried samples of the convective method. This is due to the reduction of thermal and thermal effects during MHS drying, which slows down chemical transformations and removes aromatic substances.

It is proved by the tensometric method, with the convective method due to shrinkage during dehydration, the changes during sorption and desorption are insignificant. When MHS drying, such changes are expressed: during the sorption of vapors, DFP is well restored, the capillaries swell, so the differential distribution function of the pores expands, the average radius of the capillaries increases 4 ... 6 times.

The research results make it possible to form the functional and technological parameters of cabbage powder, to simulate the formulation of new food products with this ingredient and to optimize the production technology.

The article presents main methods of studying restored whey-malty mixtures after fermentation by lactose-fermenting yeast and saccharomyces for getting a beverage of the kvass type.

The methods of accumulation of yeast cells Kluyveromyces lactis 469 and their percent with glycogen from the general concentration at fermentation of wort of the restored mixture at different ratios of dry malt and whey are offered and results are obtained. According to the obtained data, it was established, that yeast cells actively developed in the period from 4 to 16 fermentation hour at the ratio of malt and whey in the restored mixture as 1:1,5 and 1:2. The increment of cells with glycogen in mixtures with the ratio – malt:whey as 1,5:1 and 2:1 was intensive. Thus, at 36 hour of fermentation the amount of yeast was 67,2 and 68,9 % respectively from the total number of cells.

The generative capacity of yeast allowed to specify the fermentation temperature of wort of restored mixtures, cultivated by different races. It was established, that for Kluyveromyces lactis 469 the maximal accumulation of yeast (67…69 mln cell/cm3 of wort) is observed at fermentation temperature – 30…32 °С, for Saccharomyces cerevisiae Р-87 and Saccharomyces cerevisiae M-5 – 30…34 °С.

The gasochromatographic method allowed to identify side products of fermentation of fermented whey-malty wort by both lactose fermenting yeast and saccharomyces. The presented information is enough for the objective assessment of the qualitative composition of fermentation products as a result of the effect of different yeast races. The use of Saccharomyces cerevisiae Р-87 for fermentation of whey-malty wort positively influences metabolism of a producer, stimulating biosynthesis or transformation of aromatic substances of the nutritive medium. The obtained research results indicate objective possibilities for the effective functioning of the aforesaid yeast race for fermentation of restored whey-malty wort in production systems.

There was grounded the choice of ingredients for developing floury confectionary products without sugar and prospects of using amylose-free flour of waxy wheat and sunroot powder for their production. There were determined quality parameters of used flour, conditioned by the state of the protein-proteinase complex.

Based on studying technological properties of flour of waxy wheat, there was demonstrated the expedience of its use in the technology of products of yeasty dough, especially hardtacks, at replacing sugar for sunroot powder. There was offered to introduce sunroot powder at producing hardtacks with the decreased sugar content in equal shares at the stage of kneading liquid fermented dough and ready one.

There was determined the influence of using amylase-free flour of waxy-wheat and inulin-containing raw material on structural-mechanical and surface properties of dough for sugar-free hardtacks. It was demonstrated, that combined introduction of waxy wheat flour and inulin-containing raw material positively influences quality parameters of semi-products of yeasty dough at complete exclusion of sugar from their recipes. The replacement of bakery wheat flour by amylase-free one allows to get dough with sunroot powder for sugar-free hardtacks with less firmness, elasticity and tendency to adhesion.
