A Novel Framework for Multi-Document Temporal Summarization (MDTS)
Authors: Mamidala Kishore Kumar , Sanampudi Suresh Kumar 
Published: April 2021

Internet or Web consists of a massive amount of information, handling which is a tedious task. Summarization plays a crucial role in extracting or abstracting key content from multiple sources with its meaning contained, thereby reducing the complexity in handling the information. Multi-document summarization gives the gist of the content collected from multiple documents. Temporal summarization concentrates on temporally related events. This paper proposes a Multi-Document Temporal Summarization (MDTS) technique that generates the summary based on temporally related events extracted from multiple documents. This technique extracts the events with the time stamp. TIMEML standards tags are used in extracting events and times. These event-times are stored in a structured database form for easier operations. Sentence ranking methods are build based on the frequency of events occurrences in the sentence. Sentence similarity measures are computed to eliminate the redundant sentences in an extracted summary. Depending on the required summary length, top-ranked sentences are selected to form the summary. Experiments are conducted on DUC 2006 and DUC 2007 data set that was released for multi-document summarization task. The extracted summaries are evaluated using ROUGE to determine precision, recall and F measure of generated summaries. The performance of the proposed method is compared with particle swarm optimization-based algorithm (PSOS), Cat swarm optimization-based summarization (CSOS), Cuckoo Search based multi-document summarization (MDSCSA). It is found that the performance of MDTS is better when compared with other methods. Doi: 10.28991/esj-2021-01268 Full Text: PDF

Published: April 2021

The selection of the sample in a survey constitutes a significant parameter for the research process. A disagreement of opinions is observed in the field of management between researchers regarding which sample fabricates better results in surveys administered in public organizations. Some of them support that only the senior levels of the management hierarchy should participate in (Elite Orientation Model), while others support the participation of representatives from all levels (Multiple Informants Model). A questionnaire was administered to people from the three levels of Hellenic Sport Federations (HSFs) management hierarchy (employees, directors/managers, Board members) in order to investigate their perception about the degree to which excellence processes (enablers / results) were implemented. The purpose of this paper was to investigate which is the most appropriate model, regarding the selection of participants in studies about the administration /management of public organizations. Statistically significant differences regarding their perceptions for the topic under investigation were revealed, which were directly related to their level in the hierarchy. It was concluded that in similar studies the Multiple Informants Model fabricates more reliable results. Doi: 10.28991/esj-2021-01272 Full Text: PDF

Published: April 2021

Известная расчетная методика оценки риска воздействия оползневых процессов на подземный трубопровод позволяет вычислить количество возможных утечек и поломок, исходно приняв данный риск равным для всех равноразмерных отрезков трубопровода. Однако на практике равная степень подверженности оползневой опасности участков трубопровода является исключением. Таким образом, возникает необходимость разработки новой методики расчета, предусматривающей реальные условия проектирования и эксплуатации трубопровода. Авторами определено условие, при котором подверженность трубопровода утечкам и разрывам в результате воздействия оползневых процессов может достигать максимальных значений. Сделан вывод о том, что для обеспечения разумной низкой величины риска следует избегать выполнения полученной зависимости. При этом должны быть соблюдены следующие условия: трасса разделена на неравные отрезки, с увеличением длины отрезка пиковая скорость грунта убывает (то есть более протяженные участки трубопровода следует располагать вдали от зон возможной активности оползневых процессов).
The well-known calculation method for assessing the risk of landslide impact on an underground pipeline makes it possible to calculate the number of possible leaks and breakdowns, initially assuming an equal risk for all equally sized pipeline sections. However, in practice, equal exposure to landslide hazard of pipeline sections is an exception. Thus, there is a need to develop a new calculation method that provides for real conditions for pipeline design and operation. The authors determined the condition under which pipeline susceptibility to leaks and ruptures as a result of landslide impact can reach maximum values. It is concluded that in order to ensure a reasonably low risk value, the implementation of the resulting dependence should be avoided. In this case, the following conditions must be met: the route is divided into unequal segments, with an increase in segment length, the peak soil velocity decreases (that is, longer pipeline sections should be located away from possible landslide activity zones).

Изучение влияния реологических свойств нефти и нефтепродуктов на метрологические характеристики турбинных преобразователей расхода (ТПР) является актуальной научно-практической задачей, имеющей определяющее значение для производства средств измерений турбинного типа. Цель статьи - проведение и анализ результатов экспериментальных исследований по оценке зависимости относительного отклонения коэффициентов преобразования ( К ) ТПР от физико-химических свойств рабочей среды и условий перекачки. Исследования проведены на специализированном калибровочном стенде и трех системах измерений количества и показателей качества нефти (нефтепродуктов). По результатам корреляционного анализа выявлено, что наибольшее влияние на количество оборотов ТПР оказывает кинематическая вязкость и плотность рабочей среды. Показано, что при изменении объемного расхода и кинематической вязкости на одном объекте возможно прогнозирование изменения К ТПР во всем диапазоне объемного расхода, основываясь на значениях числа Re. Установленная на объекте эксплуатации градуировочная характеристика ТПР позволяет определить нижний предел диапазона измерений объемного расхода ТПР на основе значений К , рассчитанных в точках объемного расхода при текущем значении кинематической вязкости.
The study of the influence of rheological properties of oil and oil products on the metrological characteristics of turbine flow converters (TFC) is a vital scientific and practical task that is significant for manufacturing turbinetype measuring instruments. The purpose of the article is to conduct and analyse the results of experimental studies on the assessment of dependence of the relative deviation of the TFC transformation ratio ( C ) on the physical and chemical properties of working medium and pumping conditions. The studies were performed using a special calibration stand and three systems for measuring the quantity and quality indicators of oil (oil products) used in the main pipeline transportation system. Based on the results of the correlation analysis it was observed that the temperature and viscosity of the working medium have the greatest influence on the number of TFC revolutions. It was shown that with the change of volumetric flow rate and kinematic viscosity on a single facility it is possible to forecast changes of C of TFC over the whole range of volume flow based on the values of the Re number. The calibration characteristic of the turbine flow converter installed at the operation site allows you to determine the lower limit of the measurement range of the TFC volume flow, based on the C , values calculated at the volumetric flow points at the current value of the kinematic viscosity.
Defining an action-research’s content to improve a policy supporting indigents’ health in Mali: a concept mapping
Authors: Seppey Mathieu , Touré Laurence , Ridde Valéry 
Published: April 2021

Background Concept mapping (CM) is a method used to create consensus around a concept within a group of actors, which enables an empowering process for the participants through dialogues and shared information. We performed a CM, aiming to improve the operationalisation of a health policy, the RAMED, to promote healthcare access to the indigent population in Mali. Methods The CM followed five steps leading to the conceptual map development: 1) brainstorming, 2) statements’ scoring, 3) clustering, 4) statistical (hierarchical clustering and multi-dimensional scaling) and qualitative analysis, and 5) validating the map. Twenty-seven participants took place in the CM, representing eighteen organisations linked to the implementation of the policy. Results We identified seven clusters of activities towards finding the concrete and collective solutions to improve healthcare access: “funding strengthening,” “integral management and care of indigents,” “expertise creation,” “promotion and communication,” “indigents’ identification processes,” “monitoring and evaluation,” and “integration and coordination of actors.” According to scalability and priority scores, “identification processes” was the most scalable and important cluster (3.03 [±0.51] and 3.26 [±0.47]/4 respectively), while “funding strengthening” was the least scalable and important (2.59 [±0.47] and 2.76 [±0.42]/4 respectively). Conclusions Although this method is primarily exploratory and a great starting point for further collaborative research, it managed to highlight the two fundamental issues in action-research: the difficulty related to the knowledge transfer to vulnerable populations and their lack of participation in the research process. It is particularly an issue in West Africa, due to lack of empirical studies and high poverty levels. Results of this study demonstrate that CM offers an important starting point for improvements, which should focus on knowledge transfer and inclusion of vulnerable populations’ points of view.

Xenophobia and anti-Semitism in the Concept of Polish Literature
Authors: Kamusella Tomasz 
Published: April 2021

In today’s Central Europe ethnolinguistic nationalism is the region’s standard normative ideology of statehood creation, legitimation and maintenance. This ideology proposes that in spatial terms, the area of the use of national language X should overlap with the territory of nation-state X, in which all members of nation X should reside. In terms of cultural policy, this means that only works written by “indubitable” members of nation X in language X can be seen as belonging to culture X. This self-limiting pattern of ethnolinguistic “purity” (homogeneity) excluded from 20th century Polish literature much of traditional Polish-Lithuanian culture and numerous authors writing in other post-Polish-Lithuanian languages than Polish. Democratization that followed the fall of communism in 1989 partly transcended this ethnolinguistic exclusion, but the old national policy has been back since 2015.

Authors: Boyko G. , Kozlova T. 
Published: April 2021

The article describes the influence of motor activity on the physical condition of student youth. It is established that there is a tendency to decrease motor activity among modern youth. The positive effect of physical activity on physical fitness, health and psycho- emotional state has been studied. The importance of motivation for physical education classes and increase of motor activity is revealed. It was found that one of the valeological factors that contributes to the formation of the foundations of health and longevity of modern youth is physical activity; Excessive educational workload in higher education institutions has a negative impact on the process of students' recovery. In order to determine the level of physical health of student youth and motivation of physical education classes, a questionnaire and research were conducted according to the method of O. Pirogova. Harmonious development of personality provides adequate motor activity and cultural and aesthetic activities. Students of pedagogical specialties are not able to fully organize their motor activity. This is due to a fairly large mental load, low motivation to engage in physical education, non- adherence to a healthy lifestyle and insufficient efficiency of modern organization of physical education of students.
One of the most common reasons is the deterioration of the diet, reduced efficiency of traditional preventive measures, reduced physical activity due to the rapid development of information and communication technologies.

The article reveals modern approaches to optimizing motor activity of student youth. The importance of motor activity in the life of students, its impact on physical development, physical fitness, psycho-emotional state of those involved is substantiated.
The analysis of scientific publications devoted to the problem of optimization of motor activity, youth health and modeling of motor modes of students of higher education institutions is carried out. The problem of lack of motor activity in young people has been identified, which requires the search for new scientific approaches and effective solutions. It is determined that one of the most effective ways to optimize physical activity is the introduction of modern information and communication technologies in the process of physical education of higher education institutions.
Today, cardiovascular diseases, which are associated with insufficient physical activity, are becoming more common. And in a pandemic, lockdown, distance learning, there is a rapid decline in physical activity, which negatively affects not only the physical fitness of young people, but can also lead to diseases such as atherosclerosis, hypertension, angina and myocardial infarction, and so on. Their spread in our time is not accidental, it is directly related to changes in the motor regime of the majority of the population, due to modern living conditions: the rapid pace of technology, the growth of information, increasing mental stress.

Published: April 2021

A practice shows that there is a danger for police officers. There is a thought that a defence from this danger is depended on a level of physical preparing police officers. Wrong actions lead to wrong results but that has negative effect for police forces and their ability to withstand a non – law and to sustain a law.
At special literature it is also there is a necessity at physical culture for police officers and rising requirements to fulfiling work. But specialists does not always provide solving abovenamed tasks and these tasks are not always certain.
It is necessary to note that according to usual programm concerned to special physical preparing, physical exercises have to be led at certain situations and modelling the widest situations is absent; the same it is concerned to complex tests which characterize special level of physical and psychical preparing.
So the questions of improving learning process on physical preparing are important. These questions are the certain part of preparing police forces and these questions are the most active means of development of professional important qualities; these questions form high reliability of moving actions at extreme situations.
Based on the above, our literature analysis aims to increase the effectiveness of law enforcement officers in the prevention of offenses by improving physical and tactical training.
This analysis showed the following most important physical qualities that law enforcement officers must have, namely: prudence, quick reaction, physical fitness, the ability to influence people's emotions based on classes in the psychology of behavior in conflict situations, resourcefulness, self-confidence.

Published: April 2021

A modern woman’s lifestyle is extremely dynamic, which can be connected to high requirements regarding the undertaking of social and professional responsibilities in the context of added pressure of high standards of physical appearance and the need to maintain one’s physical health at a stable level, all of which causes additional stress resulting in the development of harmful lifestyle habits and, as a consequence, to the development of excess body weight.
We have conducted a study of lifestyle particularities of mature-age women, the structure, character, and volume of physical activity as a leading determinant of health maintenance. Study results demonstrate that majority of women have inadequate level of physical activity, in particular, moderate physical activity or health-enhancing fitness activity 1-2 times per week, but report the ability to practice health-enhancing physical activity during 60-120 minutes 3-4 times per week. This leads to a conclusion that women do not attach significant importance to practicing rational physical activity as part of their lifestyle. With regard to the social lifestyle characteristics, it was determined that most women have a full family, but report regular occurrence of nervous breakdowns and food intake fluctuations; interestingly, harmful habits like tobacco smoking were reported in just 8% of cases; 64% of women reported fast onset of fatigue, breathlessness and overall heightened psycho-emotional strain.
Among the main objectives of practicing health-enhancing and recreational physical activity women stated body mass normalization – 100%; health enhancement – 32%; self-esteem increase – 76%. As to the preferred format of practicing physical activity, 100% of women chose physical activity led by a personal trainer; 76% of women are willing to combine personal fitness training with group fitness classes. Collected data should be used as a justification basis for the development of a complex health- enhancement technology for overweight women according to the specific lifestyle characteristics.
