Polyphenolic Profiling of Forestry Waste by UPLC-HDMSE
Authors: Potter Colin M. , Jones David L.
Published: November 2020

Polyphenols constitute a diverse array of naturally occurring secondary metabolites found in plants which, when consumed, have been shown to promote human health. Greater consumption may therefore aid in the fight against diseases such as obesity, diabetes, heart disease, cancer, etc. Tree bark is polyphenol-rich and has potential to be used in food supplements. However, it is important to gain insight into the polyphenol profile of different barks to select the material with greatest concentration and diversity. Ultra-performance liquid chromatography (UPLC) was coupled with an ion mobility time-of-flight high-definition/high-resolution mass spectrometer (UPLC-HDMSE) to profile ethanol extracts of three common tree barks (Pinus contorta, Pinus sylvestris, Quercus robur) alongside a commercial reference (Pycnogenol® extracted from Pinus pinaster). Through the use of Progenesis QI informatics software, 35 high scoring components with reported significance to health were tentatively identified across the three bark extracts following broadly the profile of Pycnogenol®. Scots Pine had generally higher compound abundances than in the other two extracts. Oak bark extract showed the lowest abundances but exhibited higher amounts of naringenin and 3-O-methylrosmarinic acid. We conclude that forestry bark waste provides a rich source of extractable polyphenols suitable for use in food supplements and so can valorise this forestry waste stream.
Rill Erosion and Soil Quality in Forest and Deforested Ecosystems with Different Morphological Characteristics
Authors: Parhizkar Misagh , Shabanpour Mahmood , Zema Demetrio Antonio , Lucas-Borja Manuel Esteban
Published: November 2020

Rill detachment capacity is a key parameter in concentrated flow erosion. Rill erosion generally turns into gully erosion with severe environmental impacts. Changes in land use and human activities can have heavy effects in rill formation, particularly in forests subject to deforestation; soil morphology plays a significant role in these effects. However, literature reports few studies about rill detachment rates and their implications on soil quality in forest and deforested soils with different morphological characteristics. To fill these gaps, this study has evaluated the rill detachment capacity (Dc) and the main soil quality indicators in three areas (upper, middle and lower slope) of forest and deforested (for 10 years) hillslopes exposed to the north and south in Northern Iran. The variations of Dc have been measured on soil samples under laboratory conditions through a flume experiment at three slope gradients (12 to 19%) and five flow rates (0.22 to 0.67 L m−1 s−1) with four replications. The large and significant (p < 0.05) difference (about 70%) detected for Dc between forest and deforested hillslopes was associated to the higher organic matter content of forest areas; as a consequence, these areas also showed higher aggregate stability, porosity, root weight density, microbial respiration and available water. In the deforested hillslopes exposed to the south, the soil erodibility was higher by 12% compared to those exposed to the north. The differences in the monitored soil quality indicators were instead less noticeable and not always significant (p < 0.05). Conversely, Dc did not significantly change (p < 0.05) among the upper, middle and lower hillslope areas investigated in this study. Simple but accurate models to predict the rill detachment capacity, erodibility and critical shear stress of soils from indicators of soil quality or the unit stream power using regression equations are suggested. Overall, the results can support land planners in prioritizing the actions for soil conservation in deforested hillslopes exposed to the south as well as in the extensive application of the proposed equations in erosion prediction models.
Robotic Total Mesorectal Excision for Rectal Cancer: Current Evidences and Future Perspectives
Authors: Jang Je-Ho , Kim Chang-Nam
Published: November 2020

Despite the technical limitations of minimally invasive surgery, laparoscopic total mesorectal excision (LTME) for rectal cancer has short-term advantages over open surgery, but the pathological outcomes reported in randomized clinical trials are still in controversy. Minimally invasive robotic total mesorectal excision (RTME) has recently been gaining popularity as robotic surgical systems potentially provide greater benefits than LTME. Compared to LTME, RTME is associated with lower conversion rates and similar or better genitourinary functions, but its long-term oncological outcomes have not been established. Although the operating time of RTME is longer than that of LTME, RTME has a shorter learning curve, is more convenient for surgeons, and is better for sphincter-preserving operations than LTME. The robotic surgical system is a good technical tool for minimally invasive surgery for rectal cancer, especially in male patients with narrow deep pelvises. Robotic systems and robotic surgical techniques are still improving, and the contribution of RTME to the treatment of rectal cancer will continue to increase in the future.
SOCIAL INSTITUTION: GENERAL HORIZONS OF PHILOSOPHICAL ANALYSIS
Authors: Mordous Iryna
Published: November 2020

The tradition of the “social institution” phenomenon studying distinguishes the following directions of its interpretation: classical structuralism, which absolutizes the role of impersonal social structures; actionism, which is based on the priority of the life activity of subjects of social dynamics; discursive institutionalism, which combines the project of communicative society of Y. Habermas and social constructivism of J. Searle. The following components shape the social institution functionality. First, social institution produces fairly accurate criteria for acceptable and unacceptable behavior of individuals. Therefore, it is appropriate to note, if not constitutional, then regulating influence of social institutions on values, culture, morality, law, traditions, and rituals of society. Secondly, social institutions produce stable samples of hermeneutic practices, which become the primary source for interpreting the behavior of others and create prerequisites for reflection and self-analysis. And thirdly, such regulation of social life not only sets certain limits and restrictions, but also shapes the prerequisites for mechanisms of shaping meaning and highlighting the integrity of phenomena.

Authors: Nemiña Pablo , Val Maria Emilia
Published: November 2020

El trabajo analiza la nueva reestructuración de deuda argentina en clave de economía política. Se plantean dos objetivos. Primero, se analiza la dinámica del proceso de negociación y se evalúan sus resultados en función de los niveles de adhesión, la magnitud de la quita y el alivio de deuda, y las implicancias jurídicas para futuras reestructuraciones. Como resultado de una negociación en la cual ambos negociadores desplegaron estrategias distributivas, se acordó un valor comparable al promedio en procesos afines y se apeló a las cláusulas de acción colectiva (CAC), el nivel de canje alcanzado fue significativamente alto. Segundo, se analiza la interacción entre la reestructuración y la dinámica reciente de las relaciones financieras globales ante el estallido de la pandemia COVID-19. Al respecto se impulsaron cambios en los contratos de deuda que precisan los requisitos para implementar las reasignaciones y la estrategia pac man. Asimismo, la limitada cooperación financiera multilateral ante la pandemia COVID19 convierte, hoy, a la reestructuración bilateral en una decisión sagaz.

The beginning of
his reign was marked by economic growth in Czechia, the king sought to make Czechia the centre of the Holy Roman Empire. His merit is also the cultural upsurge – from the time of Charles IV to the present day, a number of architectural masterpieces have survived, and the University of Prague was founded. In addition, Charles IV became the founder of the world famous resort – Karlsbad.
THE RECEPTION OF FRANCISCAN MYSTICS IN EUROPEAN POETRY OF THE 17TH CENTURY
Authors: Volkova Anna G.
Published: November 2020

European poetry of the 17th century has its own complicated metaphoric language the interpretation of which depends on understanding of different contexts. It is especially true about religious poetry that does not only use metaphors, motifs and stories from the Bible but also perceive the biblical text through some confessions and often through some directions within a confession. Such cultural and historical code is important and necessary for reception and interpretation of poetical text. Franciscans as a special direction in Roman Catholic spirituality influenced very much on European literature and especially on religious poetry of Middle ages, Renaissance and Baroque i.e. the late 16th – 17th centuries. The main point of the article is studying of key images and motifs of Franciscan spirituality that were expressed in German mystical poetry (on
texts by Johannes Scheffler familiarly known as Angelus Silesius). Except traditional motifs of poverty, God’s love, one can find out thoughts about relationships between the Creator and its creature popular in theology and religious experience of
Franciscans in his poetry. In poetry such ideas as an experience of communication with God are transmitted through poetical language, metaphors and also through special mean of concordia discors or connecting unconnectable.
ALEXANDRE DUMAS AND A GOTHIC NOVEL (DEDICATED TO 150TH ANNIVERSARY OF THE WRITER’S DEATH)
Authors: Chekalov Kirill A.
Published: November 2020

The article considers the characteristics of interpretation by Alexandre Dumas père of a genre of gothic fiction based on the writer’s less popular works: Le Château d’Eppstein, 1843 and Le Pasteur d’Ashbourn,1853. Alexandre Dumas père deviates from the genre’s traditional surrounding, i.e. the southern France, Italy, Spain. Le Château d’Eppstein is set in Germany; by connecting the legendary past with the historical time, Dumas enhances one of the genre’s inherent features, at the same time enriching the narrative with a dense intertextual component. The events of Le pasteur d’Ashbourn happen in England. The first part of the book is a rescript of a sentimental novel Leben Eines Armen Landpredigers by August Heinrich Julius Lafontaine (1801; translated in French by Isabelle de Montolieu as Nouveaux Tableaux De Famille Ou La Vie D’un Pauvre Ministre De Village Allemand Et De Ses Enfants – 1802; translated in English as The Village Pastor and His Children – 1803), which beautifully contrasts with a traditional gothic plot of the second part and an extensive ironic epilogue. Both novels demonstrate that Dumas did not intend to imitate the gothic fiction, but rather to transform it by means of witty genre and stylistic experiments.
FEATURES OF THE EPIC NARRATIVE IN THE NOVEL «ANNA KARENINA» BY LEO TOLSTOY: FROM AUTHOR TO HERO
Authors: Gorodilova Natal’ya I.
Published: November 2020

The article is devoted to the analysis of the epic nature of the novel «Anna Karenina» by Leo Tolstoy. Artistic concept dedicated to the crisis era of the 1870s as the most important milestone in Russian history, the wide coverage of the events contemporary for the author, the depiction of representatives of different estates - testify to the scale of the creative task. The article examines the originality of Leo Tolstoy’s epic narrative, which is largely determined by the choice of the protagonist. Endowed with a sensitive heart and a troubled conscience, seeking his true destiny, such a man always goes the same path – from egocentrism to understanding of folkish life, realising himself as part of a common «swarm» life. Nikolenka Irteniev, Dmitri Nekhlyudov, Pierre Bezukhov are a complex reflection of Leo Tolstoy himself, each at a certain stage in his spiritual
biography. In the gallery of Leo Tolstoy’s heroes, Konstantin Lyovin occupies a special place, since he reflects a writer who is on the verge of a serious worldview revolution. Understanding the biographical and artistic principles in the image of Konstantin Lyovin is given in the context of epistolary and memoir sources in the article. The story of Konstantin Lyovin with his uneasy search for the meaning of life, with religious doubts, embodied the author’s innermost thoughts repeatedly expressed by him in letters to Nikolay Strakhov. Not only the most important page of Leo Tolstoy’s biography is revealed in the fate of Konstantin Lyovin, but the fate of a person of transition time closely related to the life of the country, is planned.
“THE CHERRY ORCHARD” BY ANTON CHEKHOV AND “THE ATONEMENT” BY IGNATY POTAPENKO: THE ARTISTIC INTERDEPENDENCE AND THE PLOT CORRESPONDENCE
Authors: Luchenetskaya-Burdina Irina Yu. , Poltevskaya Kseniya Ye.
Published: November 2020

It is generally recognized that the dramaturgy of Anton Chekhov had a significant impact on the theatre of the 20th century. At the same time, the question of the writer’s role in the playwright’s work of the turn of the 19th–20th centuries has been little studied in literature. Ignaty Potapenko is one of the most popular writers of the 1890s and a friend of Anton Chekhov. The article presents a comparative analysis of the plays – “The Cherry Orchard” by Anton Chekhov and “The Atonement” by Ignaty Potapenko – in which the same topic is revealed: the old nobiliary manors destruction. The plot and the conflict as the elements of writer’s dramatic method are considered. The main motifs of the plays are analysed. It is noted that the conflict of Ignaty Potapenkoʼs play is psychological and traditional for classical drama. There is no conflict between characters in “The Cherry Orchard”. The conflict is philosophical. The role of the double-characters in both plays is considered. It is proved that both plays are united by the motif of foreboding disaster, catastrophe. It is proved that both plays are united by the
motif of disaster and catastrophe premonition, existence of the internal and external plot. The ideological and thematic unity of the plays, the interconnection of some motifs, plot and compositional elements were discovered. It is shown that in the play
by Ignaty Potapenko there are elements of both classical drama and the “new drama”.
LEGAL RESPONSIBILITY FOR ECONOMIC OFFENCES
Authors: Сhurkina Lyudmila M.
Published: November 2020

The economic sphere is a specific sphere of public relations that is regulated by civil, tax, antitrust, and customs legislation. The violation of this legislation leads to the application of legal liability measures. The article is devoted to the topical problem of applying responsibility for economic offences. The author explores the legal nature of legal responsibility, examines the concept of legal responsibility, presented by various experts in the field of theory of state and law, and the principles that underlie the implementation of responsibility. The characteristic features of legal responsibility that distinguish it from other types of social responsibility are highlighted and described. The paper analyses various types of legal liability for economic wrongful acts. The special attention is paid to criminal, administrative and civil liability. The author examines certain features related to the basis of liability, its sources and subjects, as well as the features of the applied sanctions. Basing on the research, the author concludes that it is necessary to improve the institution of legal responsibility as a fundamental institution of the Russian legal system that regulates various spheres of relations, including economic legal relations.
INSTITUTION OF PUBLIC LAND SERVITUDE IN THE CONTEXT OF THE THEORY OF REFLECTIVE ACTION OF LAW
Authors: Mokhov Artem Yu. , Malyshkin Semyon P.
Published: November 2020

The main provisions of the theory of reflective action of law are considered in the article. The manifestation of law reflexes in modern legal regulation is analysed on the example of land relations. Land, as the basis of life and activity of peoples who live in the territory of the Russian Federation, acts not only as an economic good and a natural resource, but also as the object of a number of property and personal non-property relations connected with them. The institution of public land easement is
considered by the authors to be a reflex of law, that is, the restriction of the subjective right of a particular owner of a land plot in the interests of society, the state. The issue of the limitation of the right of land private ownership is raised on the basis of an analysis of legislation and judicial practice. The problem of the limits of the action of public easements simultaneously aimed not only at the normal exercise of all property rights by the land plot owner, but also at preserving the favourable state of the environment, at ensuring the subjective rights of other participants in land legal relations, at the implementation of a single land policy of the state indicated in the context of the development of land legislation of the Russian Federation. The conclusion, that the use of the right reflex construction has a beneficial effect on strengthening legal certainty in the face of imbalances in private and public interests in land law, is made.
PETER KROPOTKIN, THE PARTICIPATION OF ENLIGHTENED LEADERS OF EASTERN SIBERIA IN THE PREPARATION OF REFORMS IN THE EARLY 1860S
Authors: Sarayeva Yelena L. , Tsoy Igor’ A.
Published: November 2020

The article gives an interpretation of the views of Peter Kropotkin on the reform process in Russia in the late 1850s and the early 1860s and his ideas about the role of the provincial administration of Eastern Siberia in the preparation of the reforms. The novelty of the research lies in the analysis of Peter Kropotkin’s judgements about the perception and implementation of the reformist plans of ministries by the provincial administration, which was the most important link in the mechanism of the transformation of society. Peter Kropotkin was an active participant in this preparatory work in Chita Province and knew all the persons involved in it, therefore his testimonies and judgements are of interest for historical science. Historiography has not sufficiently studied the problem of perception by the participants of the transformations in the provinces of the course of practical implementation of the reforms conceived by the central government, in particular in Eastern Siberia. The article analyses the way of thinking of Peter Kropotkin in 1857-1863, reproduces the characteristics given by Peter Kropotkin to the governors of Eastern Siberia, his judgements about their participation in the preparation of projects of transformations in this region, we also analyse the forms of interaction of the provincial administration with the local community, interpreted Peter Kropotkin’s views on the reasons for the turn of power to reaction in the early 1860s and on the results of the transformations.
«KAZAN MUSEUM HERALD» ON MUSEUM WORK IN TATARSTAN IN THE 1920S
Authors: Sabitova Kamilla B.
Published: November 2020

The article is devoted to the consideration of the problems of formation and analysis of the content of one of the first specialised museological periodicals – Kazan Museum Herald, published in 1920-1924. The sources of the research were both the materials of the publication itself and the works of museologists who actively participated in the creation and activities of the journal. The application of methods of source study analysis allowed to consider the main range of problems that worried the museum community in the early 1920s, the directions of museum work that should have been covered in the pages of the publication and, for one reason or another, were not developed, to analyse the subject of publications and reflected in materials of the publication of museum work in different regions of the country. The conclusions of the work emphasise the importance of the publication for the development of museum work in the territory of the Tatar Autonomous Soviet Socialist Republic in the early years of Soviet power, an important place occupied in the journal by materials on the problems of the exposition, research and educational activities of the Central Museum of the TASSR. However, the specifics of the publication was the way the topic went beyond solving exclusively local problems, considering the state of provincial museums in the country, issues of theory and practice of museum work, and problems of protecting monuments. The broad scientific approach of the publication to these problems, attracting to work and publications not only local scientists, museologists, but also art historians and pedagogues made Kazan Museum Herald a unique source on the history of the formation of Soviet museum work.
Optimization Problems of Document Processing Management
Authors: Laptin Yuri , Bardadym Tamara , Lefterov Alexandr
Published: November 2020

Introduction. The use of various cloud services is becoming an integral part of modern life. At the same time, the owners of such services usually are not going to inform users with the theoretical foundations of the deployment and provision of these services, as well as with issues of security. On the other hand, as the above literature review shows, researchers often limit themselves to describing certain aspects of cloud technologies. The introduction of optimization approaches will contribute to both the development of the capabilities of providers and the rational use of resources by end users.

The purpose of the article is to offer possible formulations of optimization problems that arise in the process of document management as in traditional or in cloud environment.

Results. Three types of optimization problems arising in document management using cloud technologies are considered. The first is the problem of minimization of losses and expenses for ensuring the functioning of an information system, considered from the point of view of a user of cloud services. The services required by users that are provided by cloud technology providers are considered as resources consumed by users of cloud technology.

The second problem is the two-level problem of creating new services. It is believed that the provider already has certain services that relate to the basic second (lower) level. They can be used both for direct provision to users, and for the formation of new services of the first (top) level, created at the request of users. Here the creation of new services requires additional expenses, and a provider has to minimize them. These expenses include costs of creating new top-level services, as well as costs of processing the necessary resources of the lower level by means of a new top-level service.

In the third problem it is suggested possible formulations of optimization workflow problems that can be used both in traditional conditions and using cloud technologies.

Conclusions. Created formulations of mathematical models can be used to improve document management, in particular to minimize costs in the relationships between the user of cloud technologies and the provider of relevant services. It is recommended to use modern software tools to solve the correspondent optimization problems.

Keywords: document management, cloud technology, optimization problem.
Ellipsoid Method for Linear Regression Parameters Determination
Authors: Stovba Viktor
Published: November 2020

Introduction. Linear regression parameters determination can be formulated as a non-smooth function minimization problem, which is Lp-norm of residual of the linear equations system. To solve it non-smooth function minimization methods can be used, e.g. subgradient methods. The article [7] considers ellipsoid method application for finding Lp-solution of redefined linear equations system with 1≤p≤2. The purpose of the paper is to extend the algorithm based on the ellipsoid method for a linear regression parameters determination problem with an arbitrary value of parameter p≥2 so that under big values of p the solution of the problem equals minimax method solution, which corresponds to p=∞ case. To describe the formulation of observation approximation problem with quadratic function as linear regression parameters determination problem. To analyze algorithm work results for great number of observations and outliers. To compare the minimax method and the ellipsoid method algorithm work results for linear regression parameters determination problem with big values of parameter p. Results. The way of calculation of objective function and its subgradient values with large values of parameter p was developed and verified on example of observation approximation containing outliers with linear function. Algorithm based on ellipsoid method changes linear function parameters monotonically using parameter p adjusting, thereby permits to reject or consider these or those observations. It is shown in [3] that Least Absolute Deviations method (LAD) is advised to be used as far as it ignores outliers and reconstructs linear function accurately. Experiment results with big number of observations and outliers using p=1 confirmed that conclusion: LAD ignores outlier groups and approximates observations with linear function adequately. Least Square Method (LSM) deviates from optimal linear function if a group of outliers is present in particular area. In case of using big values of parameter p problem solution converges to minimax method solution. Conclusions. Algorithm based on ellipsoid method permits to determine linear regression parameters with arbitrary value of parameter p≥1. So, three known methods can be used – LAD, LSM and minimax method – as its special cases. Moreover, directing p to 1, intensity of outliers ignoring can be regulated, that gives a possibility to use external sources of information (expert opinions, measuring devices readings, statistical forecasts, etc.) for more correct and adequate approximation function reconstruction. Keywords: ellipsoid method, linear regression, outliers.
Multilevel Identification Friend or Foe of Objects and Analysis of the Applicability of Post-Quantum Cryptographic Algorithms for Information Security
Authors: Korolyov V. , Ogurtsov M. , Khodzinsky A.
Published: November 2020

Introduction. Widespread use of unmanned aerial vehicles in the civilian and military spheres requires the development of new algorithms for identification friend or foe of targets, as used in the Armed Forces of Ukraine (AFU) devices of the "Parol" system are designed to service approximately 110 objects military equipment. AFU automation systems allow the use of additional sources of information about various objects from civil or special data transmission networks, which can be the basis for building a networked multi-level system of state recognition. Predictions of the development of quantum computers foresee the possibility of breaking modern algorithms for information security in polynomial time in the next 5-10 years, which requires the development and implementation of new encryption algorithms and revision of modern parameters.
The purpose of the article is to develop a new algorithm for state recognition of objects, which can be scaled to process the required number of manned and unmanned aerial vehicles. Potential threats to classical cryptographic protection algorithms for data networks, which will result in the execution of algorithms such as Grover and Shore on quantum computers, were also discussed.
Results. The article proposes a new multilevel algorithm of state recognition based on modern cryptographic methods of information protection, which allows to perform reliable automated identification of objects, scale systems using data on potential targets from other sources through secure special networks. Grover's search algorithm does not give a strong increase in key search performance for symmetric encryption algorithms, so there is no need to increase the key lengths for this type of information security algorithms. Post-quantum asymmetric encryption algorithms require additional study and comprehensive testing of information security or increasing the key lengths of cryptographic algorithms, which corresponds to the number of qubits, i.e. more than twice. The most promising is the family of asymmetric post-quantum cryptographic algorithms based on supersingular isogenic elliptic curves.
Conclusions. The developed algorithm of identification friend or foe of objects is more secure compared to existing algorithms and is focused on the use of modern on-board computers and programmable radio modems. Shore's algorithm and the like will be a significant threat to modern asymmetric cryptography algorithms when the number of qubits of quantum computers exceeds the number of bits in public keys more than twice.
Keywords: identification friend or foe, symmetric encryption, asymmetric cryptography, quantum computer, post-quantum cryptography.
Approximation of the Contour of an Object in an Image Using Vector Operations
Authors: Sabelnikov P.
Published: November 2020

Introduction. One of the directions associated with identification, analysis of the shape of objects, their size, orientation, marking and other geometric characteristics is contour analysis.

Various methods for contour approximation are described in the literature. The proposed method is based on a well-known method. Its essence lies in the sequential search for possible directions and end points of approximating straight line segments belonging to the contour. The number of approximation nodes should be as small as possible. The calculation is carried out only for the next point of the contour, without returning to check the criterion of approximation to all previous points. The computational complexity of the algorithm is proportional to the number of points in the contour.

The purpose of the paper to propose a method of piecewise linear approximation of the contours of objects in images, which will allow to use the parallel computations at all stages of computer processing using vector operations.

Results. The paper proposes an improved method for piecewise linear approximation of a closed contour of an object in an image by a polygon, the vertices of which are directly the points of this contour. Approximation criterion: the distance from each point of the approximated section of the contour to the approximating segment should not exceed the approximation error. The method is focused on parallel computing using vector operations.

A method for parallel computation of integral vectors of extreme values of a sequence of numbers for the implementation of parallel computations using vector operations at all stages of approximation is also proposed.

Conclusions. Methods are proposed that are implemented using vector operations and provide an opportunity to speed up the solution of contour analysis problems, as well as other similar problems in real time. The gain in computing speed is proportional to the amount of data that a vector processor can simultaneously process. The presence of developed subsystems of vector instructions in Intel and ARM processors makes it possible to use the proposed computation methods in practice.

Keywords: image, object contour, piecewise linear approximation, parallel computations, vector operations.

Published: November 2020

Malaysian healthcare is nominated as one of the best healthcare providers in the world. However, does this fact reflect the patients' satisfaction? Therefore, this research aims to investigate whether empathy, competency, and service quality influence patients' satisfaction in healthcare services in Selangor, Malaysia. Primary data are collected using a self-administered questionnaire and a sample of 206 patients from four government and private hospitals in Selangor. Data were analysed through descriptive statistics, correlation and regression analysis. The findings show that empathy has the strongest relationship (β= .403) followed by service quality with (β=.284) and competency (β= .176). All factors also influenced patients' satisfaction. All identified variables contribute to a big amount of variances (R2=66.8percent) to the overall hospital performance that makes its client happy and satisfied. The understanding patients' satisfaction will lead to many improved services. Practically, this study can contribute to a better experience for patients and knowledge for hospitals to strive for a better service healthcare provider.
COMPUTER ENGINEERING ANALYSIS OF DOUBLE-SIDED MULTI-ARC WELDING OF VERTICAL JOINTS OF TANKS FOR STORING OIL AND OIL PRODUCTS
Authors: Filippov O. I. , Sholokhov M. A. , Erofeev V. A. , Poloskov S. I.
Published: November 2020

The possibilities of computer engineering analysis of special features of double-sided multi-arc welding of vertical joints of tanks with thick shells for storing oil and oil products are shown. The analysis was carried out on the basis of a numerical implementation of the unconventional physical and mathematical model of the formation of a melt pool and a weld seam with two pairs of arcs on each side of the joint with a double-sided bevel. It was established that during weld formation with the movement of the electrode down (vertical down), the possibility of supplying the first pair of arcs with pulsed current should be taken into account, and for the second pairs, the possibility of lateral oscillation of the arcs in the groove with delays at the edges. During groove filling with the movement of the electrodes up (vertical up), their lateral oscillations and delays at the edges should be carried out according to an aperiodic law in order to minimize the effects of “magnetic blow”. For root formation, it is recommended to use pulsed welding, and during groove filling - high current welding with low welding speed. The results of the study can be used in the formation of scientifically-based requirements for the welding process and equipment for double-sided multi-arc welding of the vertical joints of tanks for storing oil and oil products.

A ambas orillas de las artes performáticas urbanas: dos casos de territorialización cultural del paisaje ribereño en Rosario
Authors: Godoy Sebastián
Published: November 2020

El presente artículo se propone estudiar la territorialización del paisaje ribereño del Paraná a partir de dos estudios de caso. Ambos episodios ilustran una relación particular entre las artes performáticas y la ribera central de Rosario. El proceso se produjo entre finales del siglo XX y comienzos del XXI y se montó sobre el reciclaje de estructuras ferroportuarias. La hipótesis de este trabajo es que la producción cultural de la ribera, a través de las artes performáticas, fue objeto de hibridación, integración, negociación, tensión y conflicto entre diversos agentes culturales (individuales, comunitarios/autónomos, institucionales y gubernamentales). El primer caso reconstruye la creación de la Casa del Tango en un galpón ferroviario, luego del desalojo de un centro cultural autónomo dedicado en gran parte a las artes performáticas circenses: el Galpón Okupa. El segundo caso analiza la formación de la Escuela Municipal de Artes Urbanas, predominantemente performáticas, en un galpón portuario a partir de una ocupación semiautónoma inicial. Ambos desarrollos buscan poner de relieve la problemática de la gubernamentalidad cultural urbana.

Oleh karena itu, menjadi penting untuk mengenal anak didik dan cara memengaruhinya, tentu pendidik harus mengetahui berbagai teori belajar dan pembelajaran yang dikemukakan oleh beberapa ahli, salah satunya adalah teori belajar sosial yang dipelopori oleh Albert Bandura. Penelitian ini bertujuan untuk mendeskripsikan interrelasi individu, lingkungan dan perilaku dalam pembiasaan praktik hukum syara yang bersifat amaliah pada anak MI. Data dikumpulkan melalui wawancara, observasi dan dokumentasi. Analisis data terdiri dari reduksi data, penyajian data dan penarikan kesimpulan. Adapun hasil penelitian menujukkan bahwa untuk mendukung keberhasilan pembelajaran Fiqih di MI Miftahul Anwar, guru memadukan antara pemodelan, proses kognitif dan lingkungan belajar. Pemodelan melibatkan guru, orang tua dan melibatkan seluruh warga sekolah. Anak menjadi observator, mengamati sekaligus meniru tingkah laku lingkungan sekolahnya terutama dari gurunya. Dalam proses pengamatan anak melakukan proses kognitif, yang didukung oleh lingkungan sebagai penguat dari tingkah laku tersebut. Orang tua peserta didik sebagai penyokong keberhasilan pembelajaran Fiqih berperan sebagai motivator sekaligus model pula bagi anak. Dengan adanya relasi antara model, lingkungan belajar dan kognitif berupa keyakinan diri anak bahwa ia mampu dan harus berbuat sesuai dengan standar dalam ajaran agamany, maka amaliah-amaliah yang dipelajari dalam Fiqih Madrasah Ibtidaiyah dapat terinternalisasi dalam diri peserta didik.

Keterampilan membaca termasuk dari empat komponen keterampilan dalam mata pelajaran Bahasa Indonesia yaitu keterampilan menulis, membaca, berbicara, dan menyimak. Penelitian ini berfokus pada keterampilan membaca jenis keterampilan membaca permulaan pada kelas rendah. Karena dilapangan masih ditemukan sebagian kecil peserta didik yang belum terampil dalam membaca, oleh karena itu strategi Picture Word Inductive Model adalah salah satu langkah terapi yang cukup sederhana namun efektif diterapkan kepada peserta didik tersebut, baik itu bagi peserta didik yang memiliki kemampuan membaca rendah sampai kepada kemampuan sedang dan tinggi. Penelitian ini menggunakan penelitian kualitatif bersifat induktif. Subjek dalam penelitian ini adalah wali kelas 2b MIS Al Islamiyah Bangkar yang berinisial MIY dan 32 siswa kelas 2b. Berdasarkan hasil penelitian bahwa pengembangan keterampilan membaca menggunakan Picture Word Inductive Model dapat mengembangkan kualitas pembelajaran keterampilan membaca permulaan bagi kelas 2 MIS Al Islamiyah Bangkar, dengan tahapan-tahapan sebagai berikut 1) pengenalan gambar guru menggunakan konsep gambar pop up. 2) Peserta didik mengidentifikasi gambar. 3) Review kata bergambar secara audio dan visual. 4) Menyusun kata dan kalimat, bersama mengembangkan kata menjadi sebuah kalimat sederhana. Jadi hasilnya peserta didik yang memiliki keterampilan membaca rendah mulai berangsur-angsur membaik dengan tindak lanjut secara continue atau berkelanjutan disetiap pembelajarannya. Sedangkan peserta didik yang sudah memiliki keterampilan membaca sedang dan tinggi dapat mengembangkannya lebih baik lagi.

Introduction: Knowledge of food composition is crucial in the assessment of nutritional quality and potential contribution to recommended nutrient intakes. Fish plays a major role in ensuring food and nutritional security among the poor, vulnerable and rural fishing communities. However, in Nigeria, information on the nutrition content of some locally important fish species particularly after smoking or sun-drying is either lacking or missing. Aim: The present study was carried out to evaluate (i) the nutritional value of two locally smoked clupeids (Sardinella maderensis and Pellonula leonensis); (ii) in relation to recommended nutrient intakes in pre-school children (< 5 years) and elderly (men and women >70 years) and (iii) linkages between nutrient access and intake. Materials and Methods: Fresh samples were collected from Badagry Creek, smoked using local smoking kiln and analyzed according to AOAC standard method. Data were collected in duplicates and analyzed using t-test. Results: There were significant differences (P =.05) in the proximate composition except for crude fibre between the two fish species. The percentage cover of daily recommended intake of phosphorous and calcium from the two species were very low (1. 81-3.7%; 0.023% - 0.0912%) but low to moderate for zinc (2 % - 22.50%) in pre-school children and the elderly. Conclusion: Sequel to the results obtained in this study, the two smoked fish species showed good nutritive qualities for human health despite the low to moderate contents of calcium, zinc and phosphorus. Keywords: Badagry Creek, clupeids, nutritional quality, smoked fish, Nigeria, recommended nutrient intakes.

Anthocleista vogelii was investigated for the acclaimed fertility enhancing properties especially in females. The phyto-chemistry of the ethanolic leave extract of Anthocleista vogelii was determined prior to it being administered orally for 14 days to Wister albino rats. Micronor (norethisterone) or N-acetylcysteine (NAC) was given orally to induce temporary infertility in the female rats for seven (7) days prior to other treatment. The Blood samples from experimental animal groups were collected through cardiac puncture when the rats were sacrificed after the completion of fourteen (14) days extract administration. The vitamin E analysis was performed using HPLC. The hematological parameters were performed using the Sysmex® Automated Hematology Analyzer KX-21N. Biochemical evaluation of glutamic pyruvate transaminase ALT, alkaline phosphatase ALP, glutamic oxaloacetate transaminase AST, total cholesterol and total triacylglycerol was done using randox biochemical kits. The extract was found to possess Anthraquinones, Terpenoids, Flavonoids, Saponins, Alkaloids, Phenols and Phytosterols. The hematological parameters showed a significant increase (P<0.05) in absolute middle cells (basophils, eosinophils and monocytes) count. It also showed a significant reduction in the ALP, ASP, AST, TAG and cholesterol level (p<0.05). The obtained results showed a significant increase of vitamin E concentration in the female rats in the control group compared to extract treated group. The result also suggest that Anthocleista vogelii may have a role in creating the environment required for enhancing pregnancy with the Vitamin E concentration production that support the claims on the traditional use of Anthocliesta vogelii to enhance fertility in female.
Topological Circuit Theory: A Lie Group Perspective
Authors: Mikki Said
Published: November 2020

We propose a new general framework attempting a unification of circuit and quantum theories. The theory is based on our discovery of a common Lie-group-theoretic structure shared by continuous circuits and quantum systems. Applications are proposed by applying topology to selected problems in microwave network theory.
El antídoto de la corrupción: la calidad de la gobernanza
Authors: Jiménez Sánchez Fernando
Published: November 2020

Este artículo defiende la necesidad de vincular el combate contra la corrupción con un objetivo mucho más amplio como el de la mejora de la calidad de la gobernanza, pero sin el que las estrategias anticorrupción están llamadas a fracasar. Los países que mejor controlan la corrupción, son también aquellos con una mayor calidad de gobierno. Un poder ejecutivo sometido a límites efectivos en su ejercicio para garantizar la salvaguardia del interés público en todas sus actuaciones, no solo permite un mejor control de la corrupción, sino que, al mismo tiempo, también asegura unos mejores niveles de prosperidad, un mayor grado de igualdad de oportunidades, y, asimismo, unas dosis más altas de confianza institucional y social.
