Influence of sugar concentration and sugar type on the polyphenol content and antioxidant activity in spiced syrup preparation
Authors: Zayapor Mohd Nazri , Abdullah Aminah , Wan Mustapha Wan Aida
Published: March 2021

Besides their culinary roles, spices in the eastern traditional medical practices serve as a medicinal diet therapy. The polyphenol-rich content of these spices contributes to their antioxidant properties, which convey the therapeutic elements. Traditionally, these phytonutrients are orally delivered via herbal decoction, including sugar-syrup-based decoctions. However, the impact of the addition of sugar into polyphenol content and their antioxidant activities are still insufficiently researched. Therefore, this study aimed to evaluate the influence of sugar concentration and its types (refined and unrefined) on the polyphenol content and their antioxidant activities. The results of the principal component analysis (PCA) did not exhibit any specific trend on either sugar concentration or its type. As indicative evidence, reducing sugar by less than 25% in such products can be considered for lower-calorie beverage development as a means for healthier diet choice.
ESTIMATION OF THE NUMBER OF SUMMANDS OF THE CENTRAL LIMIT THEOREM
Authors:   Tver State Agricultural Academy, Ganicheva Antonina
Published: March 2021

The problem of estimating the number of summands of random variables for a total normal distribution law or a sample average with a normal distribution is investigated. The Central limit theorem allows us to solve many complex applied problems using the developed mathematical apparatus of the normal probability distribution. Otherwise, we would have to operate with convolutions of distributions that are explicitly calculated in rare cases. The purpose of this paper is to theoretically estimate the number of terms of the Central limit theorem necessary for the sum or sample average to have a normal probability distribution law. The article proves two theorems and two consequences of them. The method of characteristic functions is used to prove theorems. The first theorem States the conditions under which the average sample of independent terms will have a normal distribution law with a given accuracy. The corollary of the first theorem determines the normal distribution for the sum of independent random variables under the conditions of theorem 1. The second theorem defines the normal distribution conditions for the average sample of independent random variables whose mathematical expectations fall in the same interval, and whose variances also fall in the same interval. The corollary of the second theorem determines the normal distribution for the sum of independent random variables under the conditions of theorem 2. According to the formula relations proved in theorem 1, a table of the required number of terms in the Central limit theorem is calculated to ensure the specified accuracy of approximation of the distribution of the values of the sample average to the normal distribution law. A graph of this dependence is constructed. The dependence is well approximated by a polynomial of the sixth degree. The relations and proved theorems obtained in the article are simple, from the point of view of calculations, and allow controlling the testing process for evaluating students ' knowledge. They make it possible to determine the number of experts when making collective decisions in the economy and organizational management systems, to conduct optimal selective quality control of products, to carry out the necessary number of observations and reasonable diagnostics in medicine.
PREDICTION OF THE RISK GROUP (BY ACADEMIC PERFORMANCE) AMONG FIRST COURSE STUDENTS BY USING THE DECISION TREE METHOD

Published: March 2021

Mass education in Russian universities in specialties (direction of study) related to the exact and technical sciences is characterized by a high dropout rate, starting from the first year of study. The current level of school education, the system for selecting applicants through the USE procedure, in many cases does not guarantee that future students will be able to successfully master science-intensive specialties. An emphasis on student-centered, individual learning is possible only after students have proven themselves in the early stages of their studies. Therefore, the anticipatory identification of the ability of yesterday's applicants to study effectively is a very urgent task. In this paper, we consider methods for constructing decision trees designed to classify students, highlighting from them a lot of those (risk group) who, with a high degree of probability, will be expelled after the first academic cycle (trimester). At the same time, the minimum information about the freshmen, recorded in their personal file, is used as input data. The construction of the model was carried out according to the data on students of the applied mathematics and computer science direction of the Perm State National Research University for a five-year period of sets of 2014-2018. At the same time, the information from 2014-2017 was used for training, and the flow of 2018 was used as a test one. At the stage of machine learning, several models of decision trees were considered, which were optimized using balancing, restrictions on the maximum tree depth and the minimum number of elements in a leaf. The effectiveness of the binary classification was assessed using a matrix of inaccuracies and a number of numerical criteria obtained on its basis. As a result of machine learning, a decision tree was built, which predicted 16 out of 17 people expelled from the first trimester into the risk group. That is, for a number of reasons, they turned out to be incapable of learning in the direction of applied mathematics and computer science. In addition, it was possible to determine the level of significance of various types of initial data, showing that the results of the USE largely determine the success of students at this stage of training. The definition of the risk group provides certain guidelines for the purposeful activity of teachers and university psychologists, which ultimately can serve as a basis for improving the quality of education and reducing dropout rates. The work performed demonstrates the capabilities of data mining methods in solving poorly formalized tasks characteristic of this type of human activity.
APPLICATION OF NEURAL NETWORKS IN SIMULATION OF CLUSTER-NETWORK RELATIONS IN OIL AND GAS INDUSTRY
Authors:   Perm National Research Polytechnic University, Kozhemyakin Leonid
Published: March 2021

Despite the fact that the cluster approach is quite common in scientific works, the issues of the formation, development and evaluation of the effectiveness of cluster-network interactions remain unresolved. The research of the scientific community is based mainly on qualitative methods of cluster analysis (expert analysis, retrospective analysis, comparison method, etc.), however, the need to transform regional development and the transition to neo-economics require the use of economic and mathematical methods of analysis, and their arsenal is relatively small. which necessitates the search for new solutions. An attempt is made in the work to simulate the cluster-network mechanism in the oil and gas industry using neural networks, since the oil sector is one of the key sectors of the Russian economy, which influences the determining rates and paths of the country's socio-economic development, and is subject to the greatest regulation by the government of the country than most other sectors. The most important specific feature of the oil sector is that it is not only able to generate huge monetary resources, but also to accumulate them to solve a large number of socio-economic problems. Based on the results of the trained neural network, using the example of the indicators of the Perm Territory, predicted values of the gross regional product were made and, as a possible core of the oil industry cluster, the profit forecast of the company of the LUKOIL group.

Varying Means of Grammatical Parallelism in the Church Slavonic Translations of Psalms of the 11th–16th Centuries
Authors: Verner Inna
Published: March 2021

As a metrically organized poetic text, the Psalter is built on the principle of substantive and formal parallelism of verses and stanzas in the Hebrew text as well as in Greek and Church Slavonic translations. In the article, based on the material of Slavic translations of different times (from the Sinai Psalter of the 11 th century to the Psalter of 1552 by Maximus the Greek), cases of assimilation / dissimilation of grammatical forms in parallel text structures are considered. The variability which arises in the process of dissimilation has neither genetic (South Slavonic vs East Slavonic, archaic vs new, standard vs non-standard forms), nor functional (literary vs non-literary forms), but rhetorical nature of stylistic variation, conditioned by the structure of the text. The analysis revealed that in early Slavonic psalter redactions the choice and the number of variable grammatical forms are limited; the texts of the 16 th century, namely the Psalms of 1552 translated by Maximus the Greek, are particularly characterized by stylistic grammatical variability, concerning the most different forms (from the substantive Gen. and Dat. cases to the aorist and perfect in the 3 rd person). The examined cases of the dissimilated grammatical forms in parallel contexts of the Psalter are supported by some original Maximus the Greek's works, so that these forms should be considered as stylistic variants of the literary Church Slavonic language.
Problems on Terminology and Theoretical Description of Language Derivation Levels
Authors: Shkapenko Tatiana , Vaulina Svetlana
Published: March 2021

The paper focuses on the system of terms used in Russian linguistics to denote the processes of language derivation. The existence of significant contradictions in their using is explained by the improper assignment of the generic term "derivation" to a separate language level – word formation. It is argued that a single-word non-attributive term should serve the purpose of nominating a concept that applies to all levels of the language. The terms denoting different varieties of derivation should include attributive characteristics, as it is in the case of terminology combination "semantic derivation". The features of the cognitive mechanisms underlying each of the types of derivation are determined, and the degree of their relevance to the development criterion as a core meaning of the lexeme "derivation" is established. A general typology of derivational processes is proposed. The term "derivation" within this typology is used for denoting the process of secondary nominative signs formation in hyperonimic sense, which includes the semantic, morphological and graphical derivation levels. The internal classification of each of the above-mentioned levels is developed. The main differences between them are presented with the help of formalized semantic records. The belonging of semantic and morphological derivation to the system language processes is proved, while graphoderivation is described as an aside-system phenomenon based on the game deconstruction of a language sign and violation of the conventions of its homogeneous semiotic representation.
Church Slavonic Words имарменя, фатунъ, фортунa in Maximus the Greek’s Works
Authors: Ferro Maria
Published: March 2021

Within the linguistic research on the works of Maximus the Greek, the article raises the question of the peculiarities of an individual intellectual dictionary in his creative work. The object of this study is the authors use of three terms conveying the concept of "fate", in particular the lexical borrowing from the Greek είμαρμένη and from the Latin words fatum and fortuna, rarely used in Church Slavonic literature up to the 16 th cent. The use of significant terms is described through lexicographical analysis in the first two volumes of the modern edition of Maximus the Greeks works. Special attention is paid to the comparison of the meanings of individual words and their functioning with the data taken from the historical section of the National Corpus of the Russian language, and as well as from a selection of dictionaries of Old Church Slavonic and Church Slavonic languages, in order to identify the characteristic features of lexical preferences of Maximus the Greek. Thorough contextual analysis of the texts allows us to show how, conveying the concept of necessity caused by the stars or mysterious destiny, the author shows himself as an innovator, enriching Church Slavonic vocabulary with new borrowings. The article verifies the hypothesis about the reasons for lexical preferences of Maximus the Greek and makes assumptions about the interpretation of synonymy of the words denoting "fate" that appears in the studied texts. Linguistic goals, formulated on the basis of the results obtained, can be achieved only taking into consideration the general trends in the development of religious and philosophical thought in Europe in the Early Modern Era.
On Adjectival Attributives Blood, Direct, Peaceful as Components of Archaic Nominations of Friends
Authors: Leontyeva Tatyana
Published: March 2021

The article discusses the changes in collocability of the word friend over time. It notes that the works by A.S. Pushkin contain the forms, unexpected for the perception of the native speakers of the modern Russian language: blood friends, direct friend, peaceful friends. The analysis of the specified attributive combinations is carried out applying definitional, contextual, linguocultural analysis methods. The text material from the National Corpus of the Russian language is used. It is proved that the expression "blood friends" could denote "people connected by strong friendship" and "people of the same class". Physical kinship criterion has been proved to serve as a basis for cognitive understanding of spiritual intimacy and social class identification. However, the connection between primary and secondary semantics is not so direct here; it is mediated by the cultural layer – the custom of twinning, a form of artificial relationship noted among many peoples. Most examples of the usage of the phrase "direct friend" mean 'express your opinion to someone honestly, directly'. The expression "peaceful friends" is interpreted as based on a doubling of the meaning 'in a relationship of agreement'. The research results can be used in compiling dictionaries of the Russian language, and also in teaching linguistic disciplines.
From the History of Ossetian Studies: The Correspondence Between Georgij (Gappo) V. Baev and Giorgi Akhvlediani
Authors: Tomelleri Vittorio
Published: March 2021

After his emigration to the West, Georgij (Gappo) Baev (1865–1939), an outstanding cultural figure in Prerevolutionary Ossetia, spent many years in Germany, where he was involved in the translation of biblical texts into Ossetic and also taught his mother tongue as a lecturer at the Berlin Oriental Seminary (1922–1939). In the manuscript department of the Berlin State Library his personal archive is kept, containing a lot of interesting material, a real treasure of information not only about his personal life, but also and above all on Ossetic culture and history. The present paper features his correspondence with the Georgian linguist Giorgi Akhvlediani (1887–1973), whose personal archive is housed at the Tbilisi State University. The so far unpublished letters and postcards cover a relatively short time frame, namely from the 8 th of September 1927 to the 16 th of October 1928. Besides showing the deep respect and sincere appreciation of the two former colleagues for each other, the texts, all written in Russian, provide interesting facts which shed more light upon their biography and scientific activity. All in all, the professional and at the same time friendly correspondence, being a significant contribution to Ossetic studies, provides an insight into the nostalgic mood of the emigrant, on the one hand, and the interested tone of his counterpart, on the other.

Working Practices of Journalists: Humans or Robots
Authors: Zamkov Andrey , Krasheninnikova Maria , Lukina Maria
Published: March 2021

The article presents the results of a research aimed at studying the significant changes in journalistic practices, namely, their partial replacement by automated systems, algorithms, and robots. The necessity of understanding and adapting to these changes comprises the topicality of the research. The research included a random sampling survey of 103 Russian journalists from various mass media. The survey showed that all the respondents use smart services and automated systems at all stages of their work - from making the choice of the topic, and its development, to analyzing marketing efficiency indicators of its promotion. Each stage of working practices requires a different extent of smart technologies involvement, as well as a different set of digital tools. All this proves the authors hypothesis that smart technologies are gradually replacing most routine processes involved in journalists work. In the contemporary commentariat there is no common view on benefits of text generating algorithms and auxiliary automated systems. However, many respondents, who are actually advanced users, believe that these facilitate their work, help to fast-track the relevant processes and avoid errors in routine processes which could be made by a human. The authors recommend taking into account these data when developing university academic programs on Journalism and training programs for professionals in this sphere.

Decentralization of electricity generation based on distributed generation plants is an important segment of the new technology platform for the power industry. On the basis of this approach, significant positive effects can be obtained, which consist in reducing financial costs of energy supply, increasing the uninterrupted power supply, improving the quality of electricity and stimulating the use of renewable energy sources. Effective use of distributed generation in electric power systems requires the development of methods and tools that provide coordinated management of normal, emergency and post-emergency modes. Of particular relevance is the problem of determining the limit operating modes of networks, at the nodal points of which relatively low power generators are connected. In some situations, for example, when using small hydraulic stations, groups of such generators can be located at significant distances for 6-10-20 kV distribution networks from consumption centers. In this case there will be a noticeable limitation of the regions of static aperiodic stability. The article presents the results of developments aimed at implementing methods for determining the limit operating modes by static aperiodic stability in networks with distributed generation plants. The proposed approach is based on the limit modes equations which provide the formation of effective algorithms for the operational finding of points belonging to the boundaries of stability regions. The results of the construction of the indicated areas for a 6 kV electric network with distributed generation plants based on low-power hydraulic stations are presented. Additionally, the transient processes in the studied electric power system were simulated in the Matlab system for various space points of the controlled mode parameters.

Light-emitting diodes are ahead of traditional light sources in terms of luminous efficacy (luminous flux per unit of electrical power consumption), which arouses an increased interest in the developers of LED lamps in the standard size of incandescent lamps. When designing LED lamps for direct replacement of incandescent lamps, it is necessary to ensure a spherical light distribution in these lighting devices. The design of the lamp with filamentary LED emitting elements is recognized as the best in terms of uniformity of the spatial distribution of light. In this work, a decomposition model of an LED emitting element has been developed, which is created on the basis of the parameters of an optical-mechanical model of LED emitting crystals, and includes the following sequentially performed actions: – construction of a geometric model of the LED emitting element; – determination of the properties of the surface source of the LED emitting element and the angular distribution of radiation of the LED emitting element model as a point emitter; – development of a primary model of an LED crystal with subsequent adjustment of its parameters; – verification of the decomposition model by comparison with the experimentally measured parameters of the LED emitting element. An assessment of the quality of the LED emitting element model as a point emitter was carried out; for this, the averaged measured and modeled LIDCs were superimposed at the same azimuthal angles on top of each other. The discrepancies between the calculated and experimental data do not exceed 10%, which confirms a high accuracy of the LED emitting element model as a point emitter. The resulting file is the properties of the surface source and the value of the luminous flux of the LED emitting element, equal to FW = 254 mW. The model is characterized by increased versatility and can be used for LED emitting elements with an arbitrary configuration of LED crystals and LED lamps based on them.

In a practice, it often happens that complex engineering systems consist of several interconnected different-type simpler subsystems. An adequate model formulation for every subsystem is impractical due to the complexity of physical processes proceeding in the subsystem. In such cases, a non-detailed black-box model is commonly used. For stationary linear systems (or subsystems), the connection between an input and an output of the black-box is defined by the Volterra integral equation of the first kind with an undetermined difference kernel also known as an impulse response in the automatic control theory. It is necessary to evaluate the unknown impulse response to use the black-box model .This statement is a non-parametric identification problem. For complex systems, the problem needs to be solved both for a whole system and for every isolated subsystem that makes identification substantially complex. Formally, impulse response evaluation is a solution of the integral equation of the first kind for its kernel over registered noise-contaminated discrete input and output values. This problem is ill-posed because of possible solution instability regarding measurement noises in initial data. To find a unique stable solution regularizing algorithms are used, but specific input and output signals in impulse response identification experiments do not allow applying computational methods of these algorithms (system of linear equations or discrete Fourier transformation). In this paper, the authors propose two specific-considering identification algorithms for complex engineering systems. In these algorithms, smoothing cubic splines are used for stable calculation of first derivatives of identified system signals. The results of the complex “Heater-Blower-Room” system identification prove the efficiency of algorithms proposed.

This article analyzes the current state and a potential use of pulseoximeters in veterinary medicine. Promising optical methods such as optical coherence tomography, pulseoximeter, and hyperspectral imaging have been clinically introduced into human medicine. But even though human and small animal medicine shares a personalized modern approach, biophotonics is still rarely used in veterinary medicine. Pulseoximeters are most often used when monitoring the condition of an animal during general anesthesia. Prospective optical devices for small animals, such as dogs and cats, should be reliable and resistant to damage (for example, due to bites or chewing), offering convenient and short measurements. The potential of using pulseoximeters for pet monitoring has yet to be explored. In this paper, we considered two methods of measurement, namely lumen oximetry and reflection oximetry. Based on the literature sources, we can conclude that the method of optical reflection oximetry has the same diagnostic value as the method of lumen oximetry and therefore can be used for veterinary pulseoximeters without losing the accuracy of pulse measurement and blood oxygenation. According to the results of the existing devices review, it was found that they mainly use the lumen oximetry method. This method is convenient for performing measurements in animals under anesthesia, but it is problematic for use on actively moving animals. The purpose of this work is to develop a new model of pulseoximeter for animals. A new type of the device based on an earlier unused method is proposed, and its advantages and disadvantages are described. Components for creation are proposed and a scheme based on these components is constructed.
Rhetorical Moves and Steps of Structuring Methodology in the English Language-Based Research Articles
Authors:   Gumilyov Eurasian National University (Nur-Sultan, Kazakhstan), Baibatyrova Aigul A.
Published: March 2021

This article analyzes the moves and steps which show the descriptions of investigative activities in the research article Methodology section. Forty Methodologies have been chosen from the high impact-factor journals: Journal of English for Academic Purposes, English for Specific Purposes, Discourse Studies and Written Communication. Based on the communicative and semantic functions of text segments which structure the rhetoric of the Methodology section, this investigation has revealed three moves and a plethora of steps, including the new ones, not identified in the previous literature. The qualitative analysis enabled the author to thoroughly describe their functions. The quantitative method was used to define the frequency of the steps and delineate the more and less conventional ones. In sum, all the steps were identified in all the methodologies analyzed but they showed different frequency occurrences. Move 1 comprises nine steps. The step ‘referencing previous works’ is the most frequent. Move 2 turned out to be obligatory; it includes ten steps with a large discrepancy between the frequency occurrences of the two steps and the other eight ones. Move 3 is actualized through six steps, which also show divergent frequency occurrences. As a contribution, there have been revealed seven new steps (with a low occurrence rate though), not identified in the previous studies: ‘indicating a gap’, ‘presenting a hypothesis’, ‘stating the implications’, ‘stating the reliability of research procedures’, ‘mentioning the complexity of analysis’, ‘stating the author’s contribution’, ‘acknowledging limitations’’. Besides, the taxonomy of moves and the classification of the steps within them substantially differ from the patterns presented in the previous studies. This can be justified by the specific rhetorical structure of the analyzed Methodologies, which reflect a specific conceptual content and organizational peculiarities of structuring knowledge in the fields of linguistics and education. For an adequate understanding of information, an article should be constructed in a consistent way and have clear linguistic features. Writers employ different moves and steps of text structuring and devices of producing a communicative effect on readers. Currently, using various moves and steps for text structuring, writers undertake considerable pragmatic acts to persuasively argue and augment the acceptability of their methodological descriptions in a strongly competitive academic community.

This article reveals the current situation in education, which is characterized by individualization and intensification of educational process. It becomes important for students not just to acquire communicative speaking skills in a foreign language, but to develop their ability to interact with representatives of the international community using a foreign language as a means of communication. The need of adjusting the organization of teaching oral foreign language communication at university and developing new effective educational technologies is emphasized. A comparative analysis of the methods of teaching oral speech (Storytelling and Storyline) is carried out. The analysis is based on the key elements of the educational process the authors identify within these methods: idea, character, demonstration result of students’ activities, and structure. The main differences of these methods are revealed. They are the creation of a character in the form of a paper model, making a collage as an illustration of a story, and drama (incidents and celebration). Special attention is paid to the description of the Storyline method, which is basic in the development of a narrativecommunicative technology. It is impossible to use this method in its original form in the educational process of the university. The main part of the article is devoted to the description of the authorial narrative-communicative educational technology and its didactic potential in teaching a foreign language as a means of intercultural communication. Features of the technology are described, including integrativeness, discursiveness, contextuality, intercultural orientation, elements of communicative situation, sociocultural conditioning, interactivity, and activity. The characteristics of the technology are also considered. The methodology of teaching based on the narrative-communicative technology includes a set of steps that is consistent with the step-by-step realization of students’ cognitive and narrative-communicative activities, which stimulates gradual “immersion” in the foreign-language context by creating and reproducing the narrative. The educational technology the authors developed appears to be an innovative tool of the teacher’s transformative activity that creates favorable conditions for students’ involvement in dynamic communicative activity, a comfortable educational atmosphere, and an increase in students’ motivation. This technology is a way to reconstruct reality, in which students develop their communication and cognitive skills.
The Right to Religious Autonomy and the Case-Law of the European Court of Human Rights

In this study, the author addresses the problem of the definition and structure of the right to religious autonomy. The object of the study was the content of the two manifestations of this right that the author identified: internal governance and doctrinal autonomy in the practice of the European Court of Human Rights. The aim of this article is to determine the main areas of protection of the right to religious autonomy of religious associations and the positive experience applicable in the Russian Federation. The author describes the role of the right to religious autonomy, which is an integral part of pluralism in a democratic society and, therefore, acts as a center for protection provided by freedom of conscience. The study is based on the theoretical material of the works of both Russian (P.V. Sergeev, Yu.E. Fedotova, M.O. Shakhov) and foreign (M.E. Chopko, M.F. Moses) researchers. The extensive law enforcement practice of the European Court of Human Rights and the regulations of the European Union are also used. The methodological basis of the study is dialectical, comparative legal, formal legal, and other methods. In particular, the use of the dialectical method helped to determine the content of the concept of the right to religious autonomy, to study the dynamics of the legal positions of the European Court of Human Rights regarding a “balanced approach” to protect the autonomy of the internal management of religious associations. The use of comparative legal and formal legal methods helped to identify correlations between the case-law of the European Court of Human Rights and acts adopted within the European Union. The use of the functional method made it possible to investigate the place and role of European institutions and the nature of their governing influence on the provision and protection of the right to religious autonomy to various religious associations, including those representing a religious minority. As a result, the author comes to the conclusion that religious autonomy in its two possible manifestations—internal governance and doctrinal autonomy—directly follows from the content of the powers of freedom of conscience. Both of the manifestations are protected by European regulations although such protection cannot be considered as absolute. On the one hand, the right to religious autonomy is an integral part of the external manifestation of religious beliefs; on the other, its universal protection will jeopardize the protection of the rights of others. Nevertheless, in a situation in which the governing influence of European states is limited and the enforcement practice of the European Court of Human Rights is not entirely consistent, it seems that European institutions are aware of the importance of the right to religious autonomy. Therefore, the authorities resolve problems associated with its implementation pragmatically, trying to balance it with other rights and legitimate interests.

Güç sistemlerinde üretim ve tüketim dengesinin
sağlanabilmesi önemlidir. Optimum yük akışı (OYA) problemi generatörler, bara
gerilimlerini, bara şönt reaktörlerini/kondansatörlerini kendi güvenli
sınırlarında tutup, yakıt maliyeti ve aktif güç kayıplarını minimize etmeyi hedefler.
Bu nedenle güç sistemlerinde OYA problemi etkili bir yöntemle
çözülmelidir.  Bu yayında, Su Çevrim
Algoritması (SÇA) ve İyileştirilmiş Su Çevrim Algoritması (İSÇA) OYA problemine
uygulanmıştır. Çalışmada, amaç fonksiyonu ile toplam yakıt maliyeti ve aktif
güç kayıplarının minimizasyonu amaçlanmıştır. Yük akış problemi için önerilen
optimizasyon algoritması IEEE 30 baralı test sistemine uygulanmıştır. İSÇA algoritması
ile bulunan sayısal sonuçlar literatürde güncel olan diğer sezgisel
algoritmalar ile karşılaştırarak, bu algoritmanın etkinliği, uygulanabilirliği

İş sağlığı
ve güvenliği kanununa göre, iş yerlerinde iş sağlığı ve güvenliğinin sağlanması
için risk değerlendirmesi yapılarak risklere karşı koruyucu ve önleyici
tedbirlerin alınması gerekmektedir. İş sağlığı ve güvenliği risk
değerlendirmesinde nitel veya nicel birçok yöntem kullanılmaktadır. İş
yerlerinde yaygın olarak kullanılan Fine-Kinney risk değerlendirme yöntemine farklı
bir bakış açısı sunulan bu çalışmada, “olasılık”, “sıklık” ve
“şiddet” faktörlerine “maliyet” faktörü de dâhil edilmiş ve Çok Kriterli Kararsız
Bulanık Dilsel Terim Setleri temelli bir risk değerlendirme modeli
önerilmiştir. Önerilen model, plastik sektöründe faaliyet gösteren bir işletmenin kalıphane
biriminde uygulanarak, uzman ekibin görüşleri doğrultusunda öncelikle faktör
ağırlıkları belirlenmiş ve elde edilen ağırlıkların kullanılmasıyla tehlikeler
önceliklendirilmiştir. En yüksek öneme sahip faktör “şiddet” olurken, en yüksek
ağırlığa sahip tehlike grubu ise “yangın ve patlamaya neden olabilecek
tehlikeler” olarak belirlenmiştir. Tehlikelerin değerlendirilmesinin
ardından, yine aynı yöntem kullanılarak alınabilecek önlemler
ağırlıklandırılmış ve gerekli tedbirlerin alınması sağlanmıştır.

Hastane işletim aşamasında yangın güvenliği
sıklıkla ihmal edilir. Bu durumun başlıca nedenleri ulusal mevzuatın
yetersizliği ile personelin nitelik ve nicelik yönünden eksikliğidir. Bu
çalışmada, hastane işletim aşamasında yangın güvenliği, ilgili mevzuat ve
standartlara göre sistematik bir biçimde incelenmiştir. Çalışmanın sonunda, yönetmelikler,
 yangın güvenlik standart ve kodları bağlamında
hastane işletmesinde yangın güvenliğine yönelik bir politika önerisinde
bulunulmuştur.
