Lebendiges Mittelalter: Möglichkeiten der Vermittlung im gymnasialen Deutschunterricht
Authors: Möhren Markus 
Published: July 2017

AbstractIn the unknown worlds of medieval literature and history and their heroes, students encounter the essence of human experience and longing. Thus they also encounter themselves – despite being embedded in a profoundly different world which for a great part has become a digital world. What appears to have become distant and foreign over the centuries can nevertheless be approachable to today’s young people. These connections are not automatically clear or visible, but must be described and established anew. In skills-oriented lessons we can teach them to forge these connections by highlighting (apparently) foreign yet quite familiar phenomena and vice versa. This approach conforms with the main ideas of current competence-oriented curricula. The article focuses on the options offered by the new 2016 syllabus in the German federal state of Baden-Württemberg. The findings can, by and large, be applied in the curricula in any other German federal state.
Comparison of Interpolators Used for Time-Interval Measurement Systems Based on Multiple-Tapped Delay Line
Authors: Chaberski Dariusz , Frankowski Robert , Gurski Maciej , Zieliński Marek 
Published: July 2017

AbstractThe paper describes the construction, operation and test results of three most popular interpolators from a viewpoint of time-interval (TI) measurement systems consisting of many tapped-delay lines (TDLs) and registering pulses of a wide-range changeable intensity. The comparison criteria include the maximum intensity of registered time stamps (TSs), the dependency of interpolator characteristic on the registered TSs’ intensity, the need of using either two counters or a mutually-complementing pair counter-register for extending a measurement range, the need of calculating offsets between TDL inputs and the dependency of a resolution increase on the number of used TDL segments. This work also contains conclusions about a range of applications, usefulness and methods of employing each described TI interpolator. The presented experimental results bring new facts that can be used by the designers who implement precise time delays in the field-programmable gate arrays (FPGA).
Effect of Feature Extraction on Automatic Sleep Stage Classification by Artificial Neural Network
Authors: Prucnal Monika , Polak Adam G. 
Published: July 2017

AbstractEEG signal-based sleep stage classification facilitates an initial diagnosis of sleep disorders. The aim of this study was to compare the efficiency of three methods for feature extraction: power spectral density (PSD), discrete wavelet transform (DWT) and empirical mode decomposition (EMD) in the automatic classification of sleep stages by an artificial neural network (ANN). 13650 30-second EEG epochs from the PhysioNet database, representing five sleep stages (W, N1-N3 and REM), were transformed into feature vectors using the aforementioned methods and principal component analysis (PCA). Three feed-forward ANNs with the same optimal structure (12 input neurons, 23 + 22 neurons in two hidden layers and 5 output neurons) were trained using three sets of features, obtained with one of the compared methods each. Calculating PSD from EEG epochs in frequency sub-bands corresponding to the brain waves (81.1% accuracy for the testing set, comparing with 74.2% for DWT and 57.6% for EMD) appeared to be the most effective feature extraction method in the analysed problem.

Maintaining Connections
Authors: Fernández-Ardèvol Mireia , Sawchuk Kim , Grenier Line 
Published: July 2017

Abstract
The concepts of user and non-user are frequently deployed within media and communications literature. What do these terms mean if examined regarding age and ageing? In this article we explore and trouble these notions through an analysis of twenty-two conversations with a group of octogenarians and nonagenarians living in a retirement home. Their descriptions of their changing uses of media througout lifetime, and their encounters with mobile phones, computers, newspapers, television, radio and landline phones, are presented as a set of ‘techno-biographies’ that challenge binary divisions of use and non-use, linear notions of media adoption, and add texture to the idea of ‘the fourth age’ as a time of life bereft of decisional power. Speaking with octogenarians and nonagenarians provides insights into media desires, needs and uses, and opens up ‘non-use’ as a complex, variegated activity, rather than a state of complete inaction or disinterest.
Digital Equality and the Uptake of Digital Applications among Seniors of Different Age
Authors: Bergström Annika 
Published: July 2017

Abstract
Ageing societies are facing challenges from the perspective of the use of information and communication technologies (ICTs). There is an increase in online services relevant for the economic, political, cultural and private life. Those who participate more fully in a digitally mediated social life enjoy advantages over their digitally disadvantaged counterparts. Today’s digital divide is not first and foremost between pensioners and others, but between younger and older pensioners. Scholars identify the need for longitudinal research among younger and older seniors to understand the differences between more or less advantaged users. Based on longitudinal, representative surveys, the present study finds that there is a clear gap between younger and older seniors, and that it is closing only very slowly. Age and level of education are powerful explanatory factors whereas generational belonging and social capital contribute only to a limited extent to the understanding of Internet uptake among older adults.
Why Ageing is More Important than Being Old
Authors: Naab Thorsten , Schwarzenegger Christian 
Published: July 2017

Abstract
The idea of distinct media generations is frequently discussed in the research literature about elderly media users. This article reviews the theoretical framework of media generations and develops a contrasting perspective that focuses on the dynamics of ageing. Its line of argument is supported empirically based on ten years of longitudinal, representative German national survey data and thirty media biographical interviews. The results indicate the fluidity of generational belonging and the importance of contextual factors to assess elderly’s media use. Finally, it is concluded that media dynamics in the lives of the elderly are best examined with a concept of media generations that is not essentially derived from birth – neither of technology, nor of people.
Growing Old with Mediatization
Authors: Givskov Cecilie 
Published: July 2017

Abstract
Computers, tablets, smartphones and mobile phones enable people to act across contexts. For individuals born during the first half of the twentieth century, these social infrastructures for agency arrived late in the life course. This article presents an analysis of a set of interviews that were thematically coded to reveal ways in which the infrastructures figured in reflexive practices among older single-dwelling women. The interviews were patterned by the shared image of a ‘media world’ and the hypothesis of the indispensability of newer media for living a socially integrated life in today’s society. Control of media connected with feelings of dis- or empowerment; ultimately media amplified the participants’ feelings of being autonomous actors. I argue that the newer media infrastructures extend the scope and need for reflexivity and augment the reflexive ageing associated with the continued activity and autonomy of the third age.

Authors: González-Martínez Sophia , Soria Irma , Ayala Nahara , Portillo-López Amelia 
Published: July 2017

AbstractMarine fungal biodiversity as a new precursor of biotechnology products is poorly studied compared to its terrestrial counterpart which has been used as a rich source of bioactive compounds. Because of the importance of marine fungi, we present here the first marine cultivable fungal isolates from sea sediments of 43 to 311 m depth from the Southern California Gulf, Mexico. Seventeen selected halotolerant fungi were isolated and identified by sequencing their ITS 1 and 2 genes. They belong to the phylum Ascomycota and Basidiomycota (16 and 1 isolates). Cladosporium spp were represented by 29%, Aspergillus spp by 24%, Talaromyces spp by 12% and other species by 35%. Two fungi showed antibacterial activity against E. coli and S. aureus.
Changes in bird communities of Admiralty Bay, King George Island (West Antarctic): insights from monitoring data (1977–1996)
Authors: Sierakowski Kazimierz , Korczak-Abshire Małgorzata , Jadwiszczak Piotr 
Published: July 2017

AbstractThe paper summarizes results of twenty years of seabird observations carried out between 1977 and 1996 on the western shore of Admiralty Bay (King George Island, South Shetlands, Antarctic). Changes in population size, distribution and phenology of the breeding species as well as the appearance of non-breeding species are reported. A total of 34 species of birds were observed, including 13 breeding species. Among the non-breeding species, four were observed to visit the site regularly, six rarely, and the remaining 11 were observed only occasionally. Among breeding populations, three Pygoscelis penguin species, the main krill consumers, were most numerous. The Adélie Penguin (P. adeliae) dominated among the penguins nesting in the investigated areas, reaching 23,661 breeding pairs in 1978. Two other penguin species were less abundant with population sizes of approximately 7,200 breeding pairs for the Chinstrap Penguin (P. antarcticus) and 3,100 breeding pairs for the Gentoo Penguin (P. papua) in the same year. During the following two decades, breeding populations of pygoscelid species experienced a declining trend and their numbers were reduced by 68.0% for Chinstrap, 67.1% for Gentoo, and 33.9% for Adélie Penguins. The data reported here represent a unique reference basis and provide valuable information about indicator species, suitable for comparison with contemporary observations of bird populations in the Antarctic Peninsula region, a place of rapidly occurring climate changes and intensive harvesting of marine living resources.
Knowledge about the joy in children with mild intellectual disability
Authors: Jasielska Aleksandra , Buchnat Marzena 
Published: July 2017

Abstract
The aim of this study was to characterize the knowledge about the joy in children with mild intellectual disability. The premises relating to mental functioning of these children suggest that this knowledge is poorer and less complex than the knowledge of their peers in the intellectual norm. The study used the authoring tool to measure children’s knowledge of emotions including the joy. This tool takes into account the cognitive representation of the basic emotions available in three codes: image, verbal, semantic and interconnection between the codes - perception, symbolization and conceptualization which perform the functions of perception, expression and understanding. The study included children with the intellectual norm (N = 30) and children with mild intellectual disability (N = 30). The obtained results mainly indicate the differences in how the happiness is understood by particular groups, to the detriment of children with disability. The character of the results is largely determined by the level of organization of knowledge about the joy and accompanying mental operations. The results will be discussed, among others, in the context of the adjustment of the programs of lasting increase of happiness for people with intellectual disability.
Positivity and job burnout in emergency personnel: examining linear and curvilinear relationship
Authors: Basińska Beata Aleksandra , Gruszczyńska Ewa 
Published: July 2017

Abstract
The aim of this study was to examine whether the relationship between the ratio of job-related positive to negative emotions (positivity ratio) and job burnout is best described as linear or curvilinear. Participants were 89 police officers (12% women) and 86 firefighters. The positivity ratio was evaluated using the Job-related Affective Wellbeing Scale (Van Katwyk, Fox, Spector, & Kelloway, 2000). Exhaustion and disengagement, two components of job burnout, were measured using the Oldenburg Burnout Inventory (Demerouti, Mostert, & Bakker, 2010). The results of regression analysis revealed that curvilinear relationships between the positivity ratio and two components of job burnout appeared to better fit the data than linear relationships. The relationship between the positivity ratio and exhaustion was curvilinear with a curve point at around 2.1. A similar curvilinear relationship, but with a lower curve point, i.e., around 1.8, was observed for disengagement. It seems that beyond certain values there may be hidden costs of maintaining positive emotions at work. Also, the unequal curve points for subscales suggest that different dimensions of work-related functioning are variously prone to such costs.
Mere Recollection of Food Reduces Altruistic Behavior
Authors: Okamura Yasuto 
Published: July 2017

Abstract
The purpose of the study was twofold: Experiment 1 tested the possibility that the mere recollection of food aroused a state of hunger and that different types of food influenced the state of hunger differently; Experiment 2 tested the possibility that food cues affected altruistic behavior. In Experiment 1, 28 participants reported how hungry they felt before and after their recollection of certain foods (noodles and pudding). Results suggest that recollection of food increased hunger and that the type of food influenced the degree of hunger (F(2,54) = 31.88, p < .001, η2 = .54). In Experiment 2, 63 participants were randomly assigned to one of three recollection conditions: (1) noodles, (2) pudding, and (3) control. Participants in the two conditions described each food in detail; control group participants did not. Participants were then asked how much they would be willing to participate in an ostensible experiment. Results indicate that recollection-induced hunger reduced altruistic behavior (F(2, 60) = 4.11, p = .021, η2 = .12). Cue reactivity theory and the hierarchy of needs could explain these results.
The Effect of Chewing a Sugar-Free Gum After Oatmeal on the Postprandial Glycaemia – A Cross-Over Study
Authors: Vuletic Lea , Klaic Marija , Spalj Stjepan , Peros Kristina 
Published: July 2017

Abstract
Background and Aims: Gum chewing after a meal stimulates salivation and may affect the motility of the gastrointestinal tract and the release of hormones through neural mechanisms. This study was conducted to assess if chewing a sugar-free gum for 20 min following a meal, as recommended for dental caries prevention, influences the postprandial blood glucose levels in a period of one hour. Materials and Methods: For each of 18 participants blood glucose profile was made by measuring capillary glucose concentration in 10-min intervals within one hour following: a) chewing a sugar-free gum, b) the consumption of an oatmeal, c) chewing a sugar-free gum after the consumption of an oatmeal. Results: No statistically significant differences were found in the glycaemic response following complex carbohydrate ingestion when a gum was chewed after a meal. Conclusions: The possible influence of gum chewing on the postprandial gastrointestinal and metabolic ongoings was not reflected in the postprandial glycaemic response under the conditions of this study. A more comprehensive study which would include more variables related to vagal efferent activity, digestion and metabolism would be needed to assess if chewing sugar-free gums to exploit their caries-protective potential can influence metabolic adaptability to nutritional challenges.
Association Between Helicobacter Pylori Infection and Insulin Resistance: A Systematic Review
Authors: Popescu Decebal , Andronescu Dan , Babeș Petru Aurel 
Published: July 2017

Abstract
Most studies in the past decades show that screening of Helicobacter Pylori (HP) together with monitoring the inflammatory markers, plasma glucose and HbA1c levels can help prevent or delay type 2 diabetes mellitus. There is a double interrelation between HP infection and diabetes; thus diabetic patients are more susceptible to infection with HP via multiple mechanisms (decreased cellular and humoral immunity induced by diabetes, reducing gastrointestinal motility and secretion of hydrochloric acid, impaired glucose metabolism with the advent of chemical modifications of the gastric mucosa, the last two mechanisms favoring the intestinal colonization with HP). At the same time, those infected with HP can develop diabetes. The purpose of this paper is reviewing the data from the medical literature on the role of the chronic infection with HP on the induction of type 2 diabetes. The studies presented below lead us to the conclusion that the chronic infection with HP, in addition to local specific effects (simple gastritis, peptic ulcer and malignant diseases), also has extradigestive effects. The one approached in our work is that HP is being able to induce type 2 diabetes by complex mechanisms related to insulin resistance, chronic low-grade inflammation, decreased insulin secretion, and influences on glucose and lipid absorption.

Published: July 2017

Abstract
In the present contribution two tests for thermal fatigue testing, which have been developed in our group, are presented. First test has provided internal cooling system of sample, while second has external cooling. For both tests heating and cooling of samples are computer guided that enables very reliable results of testing. The first test is more appropriate for testing the base material, i.e. roll cast irons, roll steels, tool steels. The second test is more appropriate for experiments that are aimed for selection of appropriate tool surface treatment, i.e. laser cladding, nitriding, coating, etc., and to compare and to achieve improved resistance against thermal fatigue of produced surface layers.

Abstract
Multiple meningioma is a condition in which more than one intracranial lesion is seen in different location and these lesions may occur with or without signs of neurofibromatosis. Incidence of multiple meningioma range from 1 to 10% in different series. We report a case of multiple meningioma in a 33 years old female who had 14 intracranial lesions both supratentorially and infratentorially, and underwent surgery for large right lateral intraventricular meningioma. She had two meningiomas located in posterior fossa associated with supratentorial meningioma, which has been rarely reported.
Historiographic Aspects of Studying the Phenomenon of Pedagogical Mastery (Analysis of Ukrainian and Foreign Scholars′ Views)
Authors: Milto Liudmyla 
Published: July 2017

Abstract The article is devoted to scientific analysis of the phenomenon of pedagogical mastery. Research findings on pedagogical mastery, pedagogical creativity, pedagogical technologies have been studied in the light of historical and pedagogical paradigm. In addition, various scientific approaches and views of scholars on the essence of pedagogical mastery have been considered and the ambiguity of their scientific interpretations has been justified. The scientific category of pedagogical mastery is regarded as a social, cultural and historical phenomenon, caused by the challenges of society in line with the relevant social priorities and directions according to the goals and objectives of a particular historical period. Subsequently, complexity and multidimensionality of the notion of pedagogical mastery and presence of various scientific approaches (technological, creative, personality- and activitybased) to interpreting the scientific category have been proved. Based on the current sociocultural situation, the relevance of researches on pedagogical mastery as a scientific category has been proved and its role in training future teachers, which can be considered as a certain teaching strategy and factor in forming their readiness for innovative activity has been defined. It has been found out that diversity and interdisciplinarity of pedagogical mastery in the system of scientific knowledge promote methodological strategies for its research, the need for their systematization and complex implementation.
