Pulchre convenit improbis cinaedis. Über die Gedichte des Schlesischen Humanisten Georg von Logau (Georgius Logus)
Authors: Kasza Péter
Published: March 2018

In 1903, in the periodical Történelmi Tár [Historical Repository], Henrik Kretschmayr published a Latin satirical poem on John Zápolya by an anonymous author, written according to him in 1527. In spite of the fact that the poem has been known for more than a century, it has evaded the attention of researchers, although it is a noteworthy piece for several reasons. It is a perfect example of anti-Zápolya propaganda, outstanding among such writings in that the author had accomplished a bravoure of style by the parallel application of imitatio and aemulatio, that are characteristic of neo-Latin poetry, when paraphrasing carmen 29, one of Catullus’ most powerful invectives.

Therefore, it is not a simple satirical poem, but a text operating at various levels and capable of addressing several layers of audience. By naming the accusations against Zápolya, also known from contemporaneous pamphlets, it functions as a piece of propaganda, however, by the artful imitation of Catullus, it can also address more educated readers, who may have delighted themselves in the recognition of the allusions.

Although several poets in Habsburg service could be candidates for the authorship, it is clear that the poem was written by the Silesian poet Georg von Logau (Georgius Logus), whose volume published in 1529 includes not only this, but also other poems imitating Catullus, and even follows the ancient author in its composition. This cannot be unrelated to the fact that during his studies in Rome, Logus was the student of Pierio Valeriano, who was the first to discuss Catullus’ poetry in the form of regular university lectures.
Verstechnik oder Allusion? Antike Vorbilder in der Dichtung von Elisabetha Johanna Westonia
Authors: Nagyillés János
Published: March 2018

Elisabetha Johanna Westonia was a poet with a hard life at the beginning of the 17th century. In the court of Rudolph II, her knowledge and education was recognised by the poet Georg Carolides von Karlsberg or Georg Martin von Baldhoven, who even helped to publish her poems. Her poetry, which has often been compared to the works of Olympia Fulvia Morata, is very complex, and the ancient patterns in her genres are clearly detectable. This study intends to analyse these poetic prototypes, as well as to investigate the question whether they were only crucial as poetic tools, or whether it is possible — when interpreting Westonia’s poems — to consider them as allusions, which may recall the (ancient) original context and are used for the self-reflection of the poet.
How to sell a poetry book twice? C. Tribrachi Mutinensis Bucolicon ad Johannem Vitéz
Authors: Simon Lajos Zoltán
Published: March 2018

Gaspare Tribraco (1439 – ca. 1493) is an almost completely neglected poet despite the fact that his Bucolicon was probably the first collection of eclogues ordered in an elaborate composition during the Quattrocento. Moreover, his eclogues have survived in two different arrangements, thus offering an extraordinary possibility to analyse the humanist poet’s methods of poetry book composition. His influence was strong not only among poets who knew Tribraco personally, like Tito Vespasiano Strozzi and Matteo Maria Boiardo. The real importance and impact of his work is reflected by his influence on poets who became part of the Neo-Latin bucolic canon, first of all Baptista Mantuanus. This study is the first attempt to thoroughly analyse the structure of both eclogue collections, as well as Tribraco’s relation to classical and medieval pastoral poetry.
Supplements to the dictionary of Medieval Latin from Hungarian sources
Authors: Szovák Kornél
Published: March 2018

As a subsidiary project of the Novum Glossarium research programme the A Magyarországi Középkori Latinság Szótára [Lexicon of Mediaeval Latin in Hungary] was launched in 1934 and cooperation on it has been carried out by the UAI (Union Académique Internationale) and HAS (Hungarian Academy of Sciences, MTA) ever since. Printed editions of the project findings have been published since 1987. Thesaurus Linguae Latinae and Mittellateinisches Wörterbuch served as framework for the series, within which five regular and one supplement volumes have been published so far. These volumes comprise the dictionary entries from A—I, all of which are richly supplemented with illustrative quotations.

Our study contains entries whose illustrative quotations have been mostly collected in the past few years and have not been known before. The resulting entries either serve as new additions to the printed volumes or can complement entries lacking proper and comprehensive documentation and thus improve our knowledge of Latin vocabulary items used in the medieval Kingdom of Hungary.
Facere enim maluerunt quam promittere: Quintilian’S answer on the discidium linguae atque cordis
Authors: Dänzer Tobias
Published: March 2018

This paper seeks to shed light on Quintilian’s conception of the orator who combines moral integrity, political wisdom and rhetorical expertise. A key for understanding this concept lies in Quintilian’s polemically distorted depiction of the rude and insolent crowd of contemporary self-appointed philosophers, who serve as counterparts to the orators. While Cicero’s famous word of the discidium linguae atque cordis has enjoyed much attention among scholars, the interpretation of the discidium by one of Cicero’s most fervent admirers has been widely neglected: Quintilian carries out a distinct revaluation of the two parties — philosophers and orators — by constructing a diametrically opposed scenario to the one Cicero had drawn of the origins of the discidium in De inventione and De oratore. In the proem, Quintilian says that men of little intelligence (infirmiora ingenia) had insolently laid claim on the word ‘philosophy’, but in fact never bothered about philosophical truth. The other party, the orators, consisted of men of profound erudition and active political engagement, and were far superior to the so-called studiosi sapientiae. This led Quintilian to the pointed statement decidedly in favour of the orators: facere enim optima quam promittere maluerunt. Quintilian’s polemic against the self-appointed philosophers of his age, who form a considerable part of the Roman aristocracy, is in fact an apologetic construction to save the reputation of the rhetorician and orator from common contemporary accusations.
All we have is from the First Book — Second thoughts regarding Dionysios of Alexandria’S De natura (On Nature)

The Eusebian fragments of Dionysios of Alexandria’s περὶ φύσεως (PE 14. 23–27), representing nearly our whole preserved text, come only from the first book of this treatise. This hitherto unknown fact emerges from an overlap of two sources combined with information from a lemma.
Bryennios’ Hyle historias: The good ruler, the tyrant and their confidants
Authors: Coufalová Hana
Published: March 2018

Contrasting the character traits and the behaviour of a good ruler and a tyrant is one of the traditional motives of Byzantine literature. Essential constituents of this comparison were four cardinal virtues (temperance, prudence, justice, and fortitude), philanthropy, piousness, accession to the throne, concern for subjects, and choice of confidants. Each writer did not necessarily discuss all the elements mentioned; he simply chose those that corresponded to his intention and his conception of his literary work. The same writing strategy was used by Nikephoros Bryennios, a Byzantine military commander and historiographer of the 12th century, in his work titled Hyle historias, in which he depicted in detail the reigns of three emperors: Romanos IV Diogenes, Michael VII Doukas, and Nikephoros III Botaneiates. Bryennios ascribed to each of them some typical traits of a tyrant; Romanos lacked prudence, Michael fortitude, and Botaneiates temperance. Furthermore Romanos listened to flatterers, Michael was manipulated by the eunuch Nikephoritzes, and Botaneiates consulted the dishonest barbarian Boril and trusted the perfidious eunuch John. The examples given imply that, from the list of characteristic mentioned above, Bryennios focused on the choice of confidants and used depictions of the emperor’s confidants to complete the portrayal of the emperor himself. The aim of this paper is to analyze the application of this technique in Hyle historias, which created negative portrayals of former emperors and paved the way for the future emperor Alexios Komnenos, the true hero of Bryennios’ writing.
STRUKTUR DAN VARIABILITAS ARLINDO DI LAUT SULAWESI
Authors: S. Atmadipoera Agus , L. Mubaraq Galang
Published: March 2018

Laut Sulawesi (SUL) merupakan gerbang utama masuknya Arus Lintas Indonesia (Arlindo), yang membawa sekitar 15 Sv massa air hangat dan asin dari Samudera Pasifik menuju Samudera Hindia. Sirkulasi dan variabilitas arus di basin SUL masih belum dipahami dengan baik. Penelitian ini bertujuan untuk mengkaji pola sirkulasi, struktur vertikal arus, dan variabilitas Arlindo SUL pada  tiga level kedalaman berbeda (15 m, 130 m, dan 318 m) yang mewakili lapisan tercampur, termoklin dan bawah-termoklin. Keluaran model (2007-2012) dari model sirkulasi laut umum dengan konfigurasi INDESO digunakan untuk analisis data deret-waktu dalam penelitian ini. Hasil penelitian menunjukkan bahwa pola sirkulasi di SUL dicirikan dengan tiga wilayah arus yang unik: (a) poros utama aliran Arlindo dengan vektor arus yang kuat di sepanjang lintasannya, (b) sirkulasi siklonik di bagian selatan basin SUL, dan (c) sirkulasi antisiklonik di bagian utara basin. Struktur vertikal arus terungkap bahwa aliran Arlindo mengalami intensifikasi di kedalaman antara 150 m dan 250 m dengan kecepatan maksimum sekitar 60 cm/. Analisis power spectra density menunjukkan bahwa variabilitas arus di SUL didominasi oleh periodisitas skala intra-musiman dengan puncak spektral energi pada periodisitas antara 21 dan 59 hari. Variabilitas skala-waktu ini diduga kuat terkait dengan signal kedatangan gelombang Rossby dari sistem arus tepi batas barat ekuator Pasifik. Koherensi yang signifikan antara fluktuasi arus di lokasi inflow dan outflow, serta di basin SUL, terjadi di sepanjang sumbu utama Arlindo dengan beda fase antara 15 dan 31 hari.
An approximate formula for the H/V ratio of Rayleigh waves in compressible pre-stressed elastic half-spaces coated with a thin layer
Authors: Linh Nguyen Thi Khanh , Vinh Pham Chi , Hue Le Thi
Published: March 2018

This paper is concerned with the propagation of Rayleigh waves in a compressible pre-stressed elastic half-space coated with a thin compressible pre-stressed elastic layer. The main purpose of the paper is to establish an approximate formula for the H/V ratio (the ratio between the amplitudes of the horizontal and vertical displacements of Rayleigh waves at the traction-free surface of the layer). First, the relations between the traction amplitude vector and the displacement amplitude one of Rayleigh waves at two sides of the interface between the layer and the half-space are created. From the continuity condition at the interface and these relations, the displacement amplitude vector of Rayleigh waves at the interface is determined. Then,  a third-order approximate formula for the H/V ratio has been derived by expanding the layer displacement amplitude vector at its traction-free surface into Taylor series at the interface. It is shown numerically that the obtained formula is a good approximate one.
Robust control for a wheeled mobile robot to track a predefined trajectory in the presence of unknown wheel slips
Authors: Nguyentien Kiem , Le Linh , Do Tuan , Nguyen Tinh , Pham Minhtuan
Published: March 2018

In this paper, a robust controller for a nonholonomic wheeled mobile robot (WMR) is proposed for tracking a predefined trajectory in the presence of unknown wheel slips, bounded external disturbances, and model uncertainties. The whole control system consists of two closed loops. Specifically, the outer one is employed to control the kinematics, and the inner one is used to control the dynamics. The output of kinematic controller is adopted as the input of the inner (dynamic) closed loop. Furthermore, two robust techniques were utilized to assure the robustness. In particular, one is used in the kinematic controller to compensate the harmful effects of the unknown wheel slips, and the other is used in the dynamic controller to overcome the model uncertainties and bounded external disturbances. Thanks to this proposed controller, a desired tracking performance in which tracking errors converge asymptotically to zero is obtained. According to Lyapunov theory and LaSalle extension, the desired tracking performance is guaranteed to be achieved. The results of computer simulation have shown the validity and efficiency of the proposed controller.

Authors: Hoa Pham Quoc , Van Tran The , Dat Pham Tien , Hau Dang Trung , Ha Nguyen Viet , Hung Nguyen Manh , Trung Nguyen Thoi
Published: March 2018

A cell-based smoothed discrete shear gap method (CS-DSG3) using three-node triangular elements was recently proposed to improve the performance of the discrete shear gap method (DSG3) for static and free vibration analyses of isotropic Reissner-Mindlin plates and shells. In this paper, the CS-DSG3 is further extended for static and free vibration analyses of laminated composite shells. In the present method, the first-order shear deformation theory (FSDT) is used in the formulation due to the simplicity and computational efficiency. The accuracy and reliability of the proposed method are verified by comparing its numerical solutions with those of others available numerical results.
Reflection and transmission of quasi-P waves through an orthotropic layer sandwiched between two half-spaces
Authors: Tung Do Xuan , Kieu Nguyen Thi , Thang Luong The
Published: March 2018

In this paper, the reflection and transmission of a qP wave through an orthotropic elastic layer sandwiched between two orthotropic elastic half-spaces is investigated. The main aim is to derive the expressions in closed-form of the reflection and transmission coefficients. These expressions have been obtained by using the transfer matrix for an orthotropic layer. Based on the obtained expressions, some numerical examples are carried out to examine the dependence of the reflection and transmission coefficients on the incident angle, the wave frequency and the ratio of mass densities.

Authors: Nam Le Thi Bich , Cuong Nguyen Manh , Tran Thinh Ich , Vinh Le Quang
Published: March 2018

This research presents a continuous element model for solving vibration problems of stepped composite cylindrical shells surrounded by Pasternak foundations with various boundary conditions. Based on the First Order Shear Deformation Theory (FSDT), the equations of motion of the circular cylindrical shell are introduced and the dynamic stiffness matrix is obtained for each segment of the uniform shell. The interesting assembly procedure of continuous element method (CEM) is adopted to analyze the dynamic behavior of the stepped composite cylindrical shell surrounded by an elastic foundation. Free vibrations and harmonic responses of different configurations of stepped composite cylindrical shells on elastic foundations are examined. Effects of structural parameters, stepped thickness and elastic foundations on the free vibration responses of stepped composite cylindrical shells are also presented. Comparisons with previously published results and finite element (FE) analyses show that the proposed technique saves data storage volume and calculating time, and is accurate and efficient for widening the studied frequency range.

Chile is experiencing a process of demographic aging with an increase in the number of elderly people, a percentage of which resides in Long-term Establishments for the Elderly (LEE). However, there is little information on the reality of the elderly in these long-term care facilities, so this study was conducted to compare the epidemiological profile of the prevalent oral pathologies as well as chronic non-communicable diseases (NCDs), of institutionalized versus non-institutionalized elderly subjects. Seventy-six institutionalized and forty-three non-institutionalized subjects were examined intraorally, and their clinical health record, gender and age were obtained, according to inclusion/exclusion criteria. The results indicate that female gender is the most common, with an average age of 78.5 year, with those 80 years old and above comprising the predominant group. The most prevalent oral lesions within the institutionalized group were denture stomatitis and irritative hyperplasia, while in the non-institutionalized these two lesions were found less frequently. As for the presence of xerostomia, there was no difference between the groups. The most common condition in both groups was total maxillary and mandibular edentulous, with the latter variable present more frequently in the institutionalized group (p<0.05). The predominant NCD for both groups were arterial hypertension, arthritis-osteoarthritis and diabetes mellitus (p>0.05), and depression was the most prevalent NCD in the non-institutionalized group (p<0.05). This study provides valuable information on the epidemiology of elderly´s oral lesions and NCDs to inform the decision-making process of public health policies.

Niels Bohr, around 1930, when he tried to describe some processes in quantum physics, created the term ‘complementarity’. Bohr believed in the general epistemological and metaphysical significance of this principle. Since then several authors have used this term to capture the essential aspects of the cognitive and epistemological development of scientific and mathematical concepts (Otte and Steinbring, 1977; Kuyk, 1977; Otte, Keitel and Seeger, 1980; Otte, 1984, 1990, 1994; Douady, 1991; Sfard, 1991; Jahnke, 1992). However, what is complementarity? It is an idea or a concept! Being an idea, complementarity finds different expressions within different contexts. Mathematicians do not know what to do with ideas and they want definitions instead. In this article, we discuss different aspects of complementarity trying to clear the matter.Keywords: Mathematics Education. Philosophy of Mathematics.

Social Exclusion and Social Inclusion: Looking for an Emancipatory Alternative in the Human Sciences
Authors: Fichtner Bernd
Published: March 2018

Abstract: the article discusses social exclusion by problematizing the way in which this concept has been treated in the Human Sciences. The analysis develops from brief outline on the antinomies of modern society and current trends in the human sciences to then present a reflection on the relationships between everyday life and modern society. Finally, he discusses the potential of Vygotsky's proposal as an emancipatory alternative. It is concluded that Vygotsky opens perspectives for a qualitatively new theoretical understanding of what is deficiency and about the different practical and therapeutic experiences as a system

STREET CHILDREN IN INDIA: A STUDY ON THEIR ACCESS TO HEALTH AND EDUCATION
Authors: Dutta Nilika
Published: March 2018

Street life is a challenge for survival, even for adults, and is yet more difficult for children. They live within the city but are unable to take advantage of the comforts of urban life. This study focused primarily on access to health and education in street children from 6 to 18 years old in the Indian metropolises of Mumbai and Kolkata. The study also aimed to assess the role of social work interventions in ensuring the rights of street children. A combination of quantitative and qualitative research methodologies was used. Convenience sampling was used to recruit 100 children. Data were collected on a one-to-one basis through semi-structured interview schedules and by non-participant observation. Findings revealed that extreme poverty was the primary cause for the increasing numbers of street children. Lack of awareness among illiterate parents regarding educational opportunities kept most children away from school attendance. Factors such as lack of an educational ambience at home made it difficult for the children to work on their lessons outside the premises of the institution. It was evident that those living with their parents had better access to health care facilities than did those living on their own; however, nongovernmental organizations made significant efforts to redress this imbalance, setting up health check-up camps at regular intervals. Although exposure to harsh reality at an early age had resulted in a premature loss of innocence in most, making them sometimes difficult to work with, the nongovernmental organizations were striving to ensure child participation and the growth of individual identity. The interventionists therefore focused on developing a rights-based approach, rather than a charitable one.
CREATING FUTURES: RESIDENTIAL CARE HOMES IN HUNGARY AND SWITZERLAND COLLABORATIVELY DEVELOP THEIR CAPACITY TO EMPOWER CHILDREN AND YOUTH TO ACTIVELY REALISE THEIR OWN FUTURES

Published: March 2018

Child and youth homes in Hungary and Switzerland want to increase the chances that the approximately 1,000 children and youth in their care will transition well from residential care to other settings, will be fully included in society, and will live lives that they have reason to value. Key to this objective is the empowerment of the children and youth to take their development into their own hands, to develop ideas of a possible future, and to pursue these ideas actively and sustainably. In the project “Creating Futures”, these homes plan to collect knowledge from children, youth, staff, and managers, as well as from the literature; to develop a framework of analysis to identify current good practices, and potentials for further development; and to implement a concrete pilot project in each home. Evaluations of the learning and development process and dissemination of publications complete the project. Throughout, there will be a strong focus on the voice of children and youth. Collaborating as a community of practice and within the context of expert network FICE International, the homes will make use of their diversity for stimulating learning and development on the individual, professional, and organisational levels. This paper describes the emergence and design of the planned project.

Objective: The objectives of this study were essentially to evaluate the best technique for extracting phenolic compounds from Silybum marianum leaves.

Subjects and Methods: Two extraction methods (maceration and decoction), using four extraction solvents. The efficiency of the extraction methods was estimated by quantifying the total polyphenol contents by the Folin -Ciocalteu method and by determining the antioxidant power of the various extracts by the ability to trap the free radical DPPH °, and the influence of these parameters on the antioxidant activity.

Results: The results showed that the extracts of the leaves by maceration have contained the highest percentage yield (24.68%); the highest content in the aqueous -methanol polyphenols extract (18.75 ± 0.55 mg GAE / g DW ) against the decoction is more effective for the extraction of flavonoids and condensed tannins. The highest content of flavonoids had been recorded for the aqueous- ethanolic extract (5.08 ± 0.57 CE mg / g DW). The water had the highest content of condensed tannin (03.86 ± 0.22 TAE / g DW). On the other hand, the aqueous -ethanolic and aqueous -methanol extract of the leaves obtained by maceration have the best antioxidant capacity (73.84 ± 5.90 EAG / g DW and 73.64 ± 5.93 mg EAG / g DW respectively) and the aqueous extract of the leaves by decoction had a better antiradical power (48.64 μg / ml).

Conclusion: The extraction of phenolic compounds from Silybum marianum leaves was strongly influenced by the type of solvent and the extraction method. In addition, it is very difficult to choose an appropriate extraction solvent for all plant samples.

Authors: El-Demerdash Safaa M. , Obied Heba K.
Published: March 2018

Intensive care unit (ICU) nurses face many uncertain situations that may affect their patient care decisions and jeopardize patients’ safety.Aim: This study aimed to explore the relationship between uncertainty and patient safety culture among intensive care unit nurses at Tanta Main University Hospital.Study subject: included (155) nurses worked in intensive care units at Tanta University Main Hospital. Two tools were used Tool (I): Nurses’ Uncertainty Questionnaire. Tool (II): Patient Safety Culture Questionnaire.Results: 74.2% of participant ICU nurses’ experienced high levels of uncertainty. Above half (56.1% and 56.1%) of them always experienced being uncomfortable and confused& loss of control when facing uncertain situations in ICUs. 84.5% and 76.8% of them always used team work; and learn from past experience to deal with uncertainty. 47.1% of them evaluated patient safety in their ICUs as acceptable and bad. There was a high statistical negative correlation between the levels of patient safety culture and experiencing uncertainty by ICU nurses at p= 0.000.Conclusions: ICU nurses experienced high level of uncertainty; they rely on experience and teamwork rather than evidence-based practices to manage clinical uncertainty. High statistical significant negative correlation was found between patient safety culture and experiencing uncertainty by ICU nurses.
