Designing optimal nanofocusing with a gradient hyperlens
Authors: Shen Lian , Prokopeva Ludmila J. , Chen Hongsheng , Kildishev Alexander V. 
Published: November 2017

AbstractWe report the design of a high-throughput gradient hyperbolic lenslet built with real-life materials and capable of focusing a beam into a deep sub-wavelength spot of λ/23. This efficient design is achieved through high-order transformation optics and circular effective-medium theory (CEMT), which are used to engineer the radially varying anisotropic artificial material based on the thin alternating cylindrical metal and dielectric layers. The radial gradient of the effective anisotropic optical constants allows for matching the impedances at the input and output interfaces, drastically improving the throughput of the lenslet. However, it is the use of the zeroth-order CEMT that enables the practical realization of a gradient hyperlens with realistic materials. To illustrate the importance of using the CEMT versus the conventional planar effective-medium theory (PEMT) for cylindrical anisotropic systems, such as our hyperlens, both the CEMT and PEMT are adopted to design gradient hyperlenses with the same materials and order of elemental layers. The CEMT- and PEMT-based designs show similar performance if the number of metal-dielectric binary layers is sufficiently large (9+ pairs) and if the layers are sufficiently thin. However, for the manufacturable lenses with realistic numbers of layers (e.g. five pairs) and thicknesses, the performance of the CEMT design continues to be practical, whereas the PEMT-based design stops working altogether. The accurate design of transformation optics-based layered cylindrical devices enabled by CEMT allow for a new class of robustly manufacturable nanophotonic systems, even with relatively thick layers of real-life materials.

Published: November 2017

Abstract

BACKGROUND. Functional connection between the stomatognathic system and the acoustic-vestibular apparatus is approached with interest in topical studies, in an attempt to elucidate in depth the cause-effect relationship between pathology and symptom. The temporomandibular joint disorder may be accompanied by a series of otological symptoms such as otalgia, tinnitus and vertigo. For this reason, for a correct diagnosis, a complex clinical examination is required both on the acousticvestibular analyzer and on neighbouring structures.

MATERIAL AND METHODS. We conducted a clinical study, on a group of 97 patients diagnosed with temporomandibular joint disorder (TMJD) and treated for this pathology. All patients included in the study were evaluated by the dentist and the ENT specialist. The patients were treated at the dental clinic and then returned to the ENT clinic two months after completion of the treatment for re-examination, recording changes in otologic symptoms in order to obtain the results of the study.

RESULTS. Of the 97 patients with TMJD, 58 also associated otic symptomatology (otalgia – 74.13%, tinnitus – 53.45%, vertigo – 43.10%). The evaluation done two months after treatment of the temporomandibular joint disorder revealed a significant remission of otalgia (decrease in Mean VAS from 6.05 to 2.49), followed by vertigo (from 5.08 to 2.52) and by tinnitus (from 4.84 to 3.84). Important changes also occurred in the results of the vestibular assessments.

CONCLUSION. The most common otological symptom of patients with TMJD is auricular pain. Otalgia, tinnitus and vertigo can be improved by dental treatment of the temporomandibular dysfunction, auricular pain having the highest rate of remission.

Summary

Objectives: Metabolic syndrome (MetS) is linked to the development of type 2 diabetes and increased risk of cardiovascular disease (CVD). Physical inactivity is one of the main pathophysiological factors of MetS subjects. The aim of this study was to evaluate if 4-week supervised aerobic training had any impact on anthropometric, metabolic, hemodynamic and arterial wall parameters in MetS subjects.

Design and methods: 57 MetS subjects were randomly selected from a Lithuanian High Cardiovascular Risk (LitHiR) national primary prevention programme. Hemodynamic, cardiometabolic risk and arterial wall parameters were evaluated after the 4-week supervised aerobic training.

Results: After 4 weeks of aerobic training there was statistically significant decrease in body mass index from 30.58 ± 3.7 to 30.3 ± 3.55 kg/m2 (p = 0.010), waist circumference from 104.24 ± 9.46 to 102.9 ± 9.48 cm (p = 0.003), decrease of LDL cholesterol from 4.21 ± 1.15 to 3.78 ± 1 mmol/l (p = 0.032) and high sensitivity C-reactive protein from 2.01 ± 2.36 to 1.64 ± 1.92 mg/l (p = 0.009), decrease of diastolic blood pressure (BP) from 83.06 ± 10.18 to 80.38 ± 8.98 mmHg (p = 0.015), mean BP from 100.03 ± 10.70 to 97.31 ± 8.88 mmHg (p = 0.027) and aortic stiffness, assessed as carotid-femoral pulse wave velocity, from 8.34 ± 1.26 to 7.91 ± 1.15 m/s (p = 0.034).

Conclusions: In subjects with MetS even short-duration (4-week) supervised aerobic exercise training is associated with improvement of some anthropometric, metabolic and hemodynamic parameters as well as the decrease in aortic stiffness. This training modality could be recommended for initiation of physical training and could increase motivation for further physical activity.

Published: November 2017

Abstract
Constant loading and transportation of materials cause abrasive wear in industrial floors. This study compared destructive and nondestructive testing techniques to evaluate the abrasion resistance of concrete. Eight concrete hardeners (six solid and two liquid) were subjected to abrasion, ultrasound, and rebound hammer tests. The results of the trials were compared to identify the concrete hardeners that provide more abrasion strength, and also to determine the relationships between the tests. The results indicated that solid hardeners provide more abrasion resistance than liquid ones and that the abrasion, as a destructive test, and the rebound hammer, as a nondestructive test, show similar results.
Non-Destructive Evaluation of the Bending-Fatigue Damage in Carbon-Fiber-Composite Laminates Based on Ultrasonic Wave Propagation
Authors: He M. , Yang T. 
Published: November 2017

Abstract
An ultrasonic technique was employed to evaluate the three-point bending-fatigue damage of carbon-fiber-composite laminates. Ultrasonic testing experiments and fracture-failure tests were performed on fatigue specimens who were damaged at fatigue loading stress levels of 75 %, 80 %, and 85 % of ultimate bending stress. The ultrasonic velocities, attenuation coefficients, and the residual stiffness were determined for specimens with different degrees of fatigue damage, and the relationships between the ultrasonic velocity and attenuation coefficient and the degree of fatigue damage were investigated. The results show that the ultrasonic velocity decreases and the attenuation coefficient increases with accumulating fatigue damage. The degree of fatigue damage can be modeled as an exponential function of the ultrasonic velocity or the attenuation coefficient. The bending-fatigue damage was found to rapidly increase once the change rate of the ultrasonic velocity or the change rate of the attenuation coefficient had reached 6.2 % or 351.25 %, respectively, and these values can be used as critical values for evaluating the bending-fatigue damage. The proposed method provides a potential way for the non-destructive evaluation of the fatigue damage in composite components in service by the ultrasonic velocity and attenuation coefficient.

Published: November 2017

Summary
A phaeochromocytoma (PC) is a rare, catecholamine-secreting neuroendocrine tumour arising from the adrenal medulla. Presenting symptoms of this rare tumour are highly variable but life-threatening multiorgan dysfunction can occur secondary to catecholamine-induced hypertension or hypotension and subsequent cardiovascular collapse. High levels of circulating catecholamines can induce an acute stress cardiomyopathy, also known as Takotsubo cardiomyopathy. Recent studies have focused on early diagnosis and estimation of the prevalence of acute stress cardiomyopathy in patients with PC, but very little is reported about management of these complex cases. Here, we report the case of a 38-year-old lady who presented with an acute Takotsubo or stress cardiomyopathy and catecholamine crisis, caused by an occult left-sided 5 cm PC. The initial presenting crisis manifested with symptoms of severe headache and abdominal pain, triggered by a respiratory tract infection. On admission to hospital, the patient rapidly deteriorated, developing respiratory failure, cardiogenic shock and subsequent cardiovascular collapse due to further exacerbation of the catecholamine crisis caused by a combination of opiates and intravenous corticosteroid. An echocardiogram revealed left ventricular apical hypokinesia and ballooning, with an estimated left ventricular ejection fraction of 10–15%. Herein, we outline the early stabilisation period, preoperative optimisation and intraoperative management, providing anecdotal guidance for the management of this rare life-threatening complication of PC.

Learning points:

A diagnosis of phaeochromocytoma should be considered in patients presenting with acute cardiomyopathy or cardiogenic shock without a clear ischaemic or valvular aetiology.

Catecholamine crisis is a life-threatening medical emergency that requires cross-disciplinary expertise and management to ensure the best clinical outcome.

After initial resuscitation, treatment of acute catecholamine-induced stress cardiomyopathy requires careful introduction of alpha-blockade followed by beta-blockade if necessary to manage β-receptor-mediated tachycardia.

Prolonged α-adrenergic receptor stimulation by high levels of circulating catecholamines precipitates arterial vasoconstriction and intravascular volume contraction, which can further exacerbate hypotension. Invasive pressure monitoring can aid management of intravascular volume in these complex patients.
Alexithymia predicts loss chasing for people at risk for problem gambling
Authors: Bibby Peter A. , Ross Katherine E. 
Published: November 2017

Background and aims
The aim of this research was to investigate the relationship between alexithymia and loss-chasing behavior in people at risk and not at risk for problem gambling.

Methods
An opportunity sample of 58 (50 males and 8 females) participants completed the Problem Gambling Severity Index and the Toronto Alexithymia Scale (TAS-20). They then completed the Cambridge Gambling Task from which a measure of loss-chasing behavior was derived.

Results
Alexithymia and problem gambling risk were significantly positively correlated. Subgroups of non-alexithymic and at or near caseness for alexithymia by low risk and at risk for problem gambling were identified. The results show a clear difference for loss-chasing behavior for the two alexithymia conditions, but there was no evidence that low and at-risk problem gamblers were more likely to loss chase. The emotion-processing components of the TAS-20 were shown to correlate with loss chasing.

Discussion and conclusion
These findings suggest that loss-chasing behavior may be particularly prevalent in a subgroup of problem gamblers those who are high in alexithymia.

Zrewidowany paradygmat systemowy. Wyjaśnienia i dodatkowe elementy w świetle doświadczeń państw postsocjalistycznych – część pierwsza
Authors: Kornai János 
Published: November 2017

The term paradigm was introduced to the philosophy of science by Thomas Kuhn – he used this term to denote the specific approach applied by a school of research to examine its subject matter. Using the same paradigm, researchers seek answers to similar questions, and employ similar methods and concepts. In an article published in 2000, the author of this essay introduced the term system paradigm, which focuses on the systems functioning n a society. This study develops the theoretical considerations outlined in that earlier article on the basis of experience of post-socialist transition. The first part compares the socialist and capitalist systems, describing their main characteristics, and concludes that the capitalist system has become established in former socialist countries, except for North Korea and Cuba.The second part analyzes varieties of capitalism within a typology which classifies prevailing forms of politics and government. Three markedly different types are identified: democracy, autocracy, and dictatorship. Huntington wrote about the “third wave” of democratization. This study concludes the third wave has dried up: for the 47 postsocialist countries, only a tenth of the population live in democracies, while autocracy or dictatorship prevails in all other countries in this group. The third part of this essay applies the conceptual and analytical apparatus to Hungary, where capitalism exists, and autocracy is the prevailing politico-governmental form – here we can find important characteristics common to other capitalist countries or other autocracies. This finding is compatible with the observation that there are some less fundamental characteristics unique to Hungary, or “Hungarica”, which differ from the characteristics of all other countries.

New generation console game technologies; Console game application supported with projection mapping
Authors: Soylucicek Seza 
Published: November 2017

AbstractUp to now the relationship between console games and gamers has been restricted by limitations in screen size. The gradual enlargement of these sizes has accommodated for a technological boom in the development of game software programs, some of which have been hugely successful and had broad repercussions across both the gaming and technological landscape. In 2010, Microsoft and their Kinect team released an advertisement using projection mapping technique, which gave users an exciting preview of the future of game technology and provided inspiration for aspiring young game developers. With the help of new techniques, developers had the chance to produce artistically unique projects by creating a variety of different game experiences. Additionally, the enhancement of digital games, their interactive features, and the enlargement of the screens enabled users to experience a completely new level of immersion in their games. Each new development within the industry allows for new avenues of exploration and provides the potential to further refine and enhance successful techniques. Two creative examples of application adaptations are Microsoft’s Illumiroom and RoomAlive projects, which include a game experience which incorporates a large part of the user’s physical environment using reflective techniques. The world of gaming entertainment and the technological advancements which propel it, are constantly improving the experience of its users, and this study, which starts out with aforesaid improvements, further examines the relationship between new generation interactive console games, aesthetic aspects of game interface designs, Microsoft Kinect and Projection Mapping. In light of these, this study discusses the future opportunities of console development, the current industry innovators, and the potential immersive qualities of digital games.

Published: November 2017

The objective needs of the individual and society for protection against dangers arising from the human encroachment have now reached the maximum extent. The aim of the paper is to define how folklore peculiarities affect the formation of human security behavior culture.The relevance of the problem under study is due to the fact that the human security behavior culture has always been in the focus of any ethnic group’s attention, which was reflected in mythology, fairy-tales, epics, proverbs and sayings. The people, the genius creator of the language and the teacher all in one, brought into being the greatest works of artistic expression that are intended to lead children in all stages of their emotional and moral development. Folklore contains the richest material for the development of moral qualities. Folklore is diverse and rich in various types and genres. The aim of the article is thus to determine the characteristics of folklore essential for the formation of human security behavior.The main approach in studying the present problem is the following: sociometric method, allowing to define the competence level of second year students from different faculties in the sphere of ethno-pedagogics and security culture, that made it possible to study how students perceive psychological difficulties they are faced with.As a result of the study the students found the use of oral folklore like fairy tales, proverbs, sayings, epics and games pedagogically practical in education of pupils’ security culture.The future teachers noted that the task of adults is teaching the child to choose the right ways of psychological defence, depending on life circumstances, rather than protecting the child from adverse surroundings.Tales about safety are textbooks of life. They give the name and understanding for quite many life situations, they help modeling correct behavior in children as well as supporting faith in goodness.The article may be useful for teachers and future educators.

Published: November 2017

AbstractArt; when setting up the combined connection of feelings and thoughts, it is a very effective helper of learning and development. It developes one's source of explanation better, form of expression and other disciplines. That is why, in modern eductaion systems science and art should be nested together. Collaboration of different disciplines in art education started to gain importance towards the end of the 20th century. Because both fields are aimed for service development and discovery of the new, when feelings are educated, mental abilities, thoughts and intelligence have been seen to be developed. In this study, the key actions of the art education in the 20th century education has been briefly noted and towards the end of the 20th century with the importance gained from different disciplines with art the new created discipline based art education and approach to interdisciplinary art has been investigated.

The Metaphoric Perceptions of Architectural Design Students On The Concept Of Jury System In Architectural Design Education
Authors: Özdemir Elvan Elif , Cengizoglu Fulya Pelin 
Published: November 2017

The core of the architectural curriculum is based on the design studio which focuses on learning by doing. The learning process in the design studio is takes place in critic sessions. These sessions are kind of communication of ideas and transmitting of knowledge from instructor to student. In contrast to other disciplines, in the architectural design education the evaluation and the assessment are the important part of the learning and teaching process. The Jury system is a traditional architectural learning assessment tool. In this system the student present his/her work in the front of the jury and get feedback or criticism. According to Webster (2006), Jury is the most performative stage of education where the student and agency (the discipline of architecture-as represented by the critics) actually interact. (Webster, 2006). The aim of this study was to reveal the perceptions of architectural design students’ about the ‘Jury system’ as an grading system in architectural design studios. The participants for this study included second, third and fourth grade architectural design students enrolled in the Department of Architecture at the Faculty of Architecture of Mersin University during the 2014-2015 school year. To collect data, each participant was asked to complete the prompt “A jury is like . . . …because . . . …..” . Phenomenological design was used in the study. The content analysis technique was used to analyze and interpret the study data. The detailed discussion will be presented in full paper.
