The World of Iberian Ham and its Tourist Potential in the Sierra De Huelva (Andalusia, Spain)
Authors: Pizarro-Gómez Antonio , Šadeikaitė Giedrė , García-Delgado F. Javier
Published: October 2020

In the context of agricultural post-productivity, rural spaces acquire new functions or reinforce the existing ones. Thus, the production of quality food, as a part of agroindustry, and tourism appear as common activities in rural development strategies. Special attention is drawn to gastronomic tourism and the creation of routes as a creative expression of the integration and structuring of the territories. The Iberian ham is a unique product, known worldwide, produced exclusively in the SW quadrant of the Iberian Peninsula. It is linked to a unique agro-system of the anthropised Mediterranean forest, also known as dehesa4
, and comparably limited Iberian pig livestock, which has given rise to traditional culture and industry constituted in Local Productive System in many municipalities, supported by Protected Designation of Origin. The central objective of the research is to analyse existing tourist attraction related to the Iberian ham, its potential and the routes and products that have arisen around it. Having placed the territorial recognition as the starting point, the analysis of the resources and locations of the activities related to the Iberian ham was carried out based on scientific literature and the use of different databases. Secondly, the analysis of the potential tourism activities in the Sierra de Huelva region was implemented based on primary sources, namely surveys and interviews with intervening actors. The following results are obtained: a) the tourist potential of the Iberian pig world; b) complementarity with other tourist activities; c) difficulties in structuring existing attractions; d) multiplication of disconnected and sometimes coincident tourism initiatives; e) scarce participation of private actors in the initiatives launched.

Published: October 2020

Ensuring aircraft are technically safe to operate is the realm of airworthiness, literally worthy of being in the air. This is achieved not only with technological tools and techniques, or with just personnel and manpower, it is guided and supervised by managers and leaders. As such, the objective of this paper is to understand the role leadership plays in maintaining aviation safety and aircraft airworthiness. To this end, a case study of the Hawker Sidley Nimrod XV230 accident that occurred on September 2, 2006 near Kandahar in Afghanistan, was utilized. The study concluded that leadership is a key aspect, specifically finding that leaders are responsible for articulating the organizations vision, strategic objective setting, and monitoring the achievement of those objectives. It was concluded that operational airworthiness is directly dependent on the leadership ability to provide direction, workplace culture, continued learning, and establish risk management systems for safe and airworthy operations.
Mining Cardinality Restrictions in OWL
Authors: Potoniec Jedrzej
Published: October 2020

We present an approach to mine cardinality restriction axioms from an existing knowledge graph, in order to extend an ontology describing the graph. We compare frequency estimation with kernel density estimation as approaches to obtain the cardinalities in restrictions. We also propose numerous strategies for filtering obtained axioms in order to make them more available for the ontology engineer. We report the results of experimental evaluation on DBpedia 2016-10 and show that using kernel density estimation to compute the cardinalities in cardinality restrictions yields more robust results that using frequency estimation. We also show that while filtering is of limited usability for minimum cardinality restrictions, it is much more important for maximum cardinality restrictions. The presented findings can be used to extend existing ontology engineering tools in order to support ontology construction and enable more efficient creation of knowledge-intensive artificial intelligence systems.
Bacterial wetwood of silver birch (Betula pendula roth): symptomology, etiology and pathogenesis
Authors: Goychuk Anatoliy F. , Drozda Valentin F. , Shvets Marina V. , Kulbanska Ivanna
Published: October 2020

The article is focused on microbiological and silvicultural properties of bacterial wetwood of silver birch (Betula pendula), also known as European white birch. During the active phase of the disease, bacterial wetwood (i.e. bacterial dropsy, vascular parenchymatous bacteriosis or flux slime) is characterised by crust and periderm bloating, necrotic wet stains and abundance of exudate. The disease is more likely to occur in older (r = 0.56, p < 0.01) and less-dense (r = −0.29, p < 0.01) stands.

The statistical model showed that the chance of bacterial wetwood increases with birch age by 0.36% per year. The stands with birch proportion of over 70% demonstrated 15.3% lower infection rate compared to the stands with lower birch presence. The stands with lower stocking demonstrated a higher proportion of infected tree distribution by 7.5% compared to the stands with higher birch representation. The most vulnerable were larger, older B. pendula trees with longitudinally fissured bark that grow on poorer soils and experience frequent water stress.

Birch associations with Pteridium aquilinum and Vaccinium myrtillus were more susceptible to infection (31.6% and 44.3%, respectively), whereas associations with Brachypodium sylvaticum, Sphagnum palustre and Calluna vulgaris were at lower risk. Strong ecological and trophic association of bacterial wetwood was present between silver birch and Tremex spp., particularly Tremex fuscicornis. Mycobiota was represented by Rhizopus microsporus, Mucor mucedo, Penicillium aurantiogriseum, Penicillium purpurogenum and Acremonium strictum.

Enterobacter, Xanthomonas, Pantoea and Bacillus spp. associated with bacterial wetwood of silver birch were isolated. Enterobacter nimipressuralis was found to be the primary causative agent through means of artificial infection, while other bacteria were found to be either weak pathogens or concomitant. E. nimipressuralis formed the largest number of colony-forming units (CFU) for bark and cambium (164 and 127 CFU, respectively) and was also found in a small amount as a vital obligate in the automicrobiota in healthy birch trees.

Published: October 2020

Cornelian cherry fruits are quite rich in bioactive compounds. Natural colour, rich flavonoids and anthocyanins and high antioxidant activity have made the fruits a natural drug. In the present study, antioxidant activity, total flavonoids and total phenolics of naturally growing 18 cornelian cherry genotypes with different phenotypic characteristics were determined. Size and shape parameters of the genotypes were also determined with the image-processing method; sphericity, elongation and shape index were calculated and shapes of two-dimensional fruit images were compared with elliptic Fourier analysis. Antioxidant activity, total flavonoid contents and total phenolic amounts of the genotypes were varied between 55.062 and 152.420 mmol TE · kg−1, 286.40 and 2,882.80 mg QE · kg−1, and 2,644.80 and 12,959.00 mg GAE · kg−1, respectively. Multivariate variance analysis conducted based on physical characteristics revealed that six genotypes were different from the others. Shape analysis with Elliptic Fourier method revealed that the majority of present cornelian cherry genotypes had an oval appearance and a small portion of them had a drop-like appearance. According to discriminant analysis and Hotelling's pair-wise comparison tests, there were five different shape groups for present genotypes. A single genotype was placed into one of these groups, thus it was determined that this genotype was totally different in shape from the others.

Tetanus in Animals — Summary of Knowledge
Authors: Malinovská Z. , Čonková E. , Váczi P.
Published: October 2020

Tetanus is a neurologic non-transmissible disease (often fatal) of humans and other animals with a worldwide occurrence.Clostridium tetaniis the spore producing bacillus which causes the bacterial disease. In deep penetrating wounds the spores germinate and produce a toxin called tetanospasmin. The main characteristic sign of tetanus is a spastic paralysis. A diagnosis is usually based on the clinical signs because the detection in the wound and the cultivation ofC. tetaniis very difficult. Between animal species there is considerable variability in the susceptibility to the bacillus. The most sensitive animal species to the neurotoxin are horses. Sheep and cattle are less sensitive and tetanus in these animal species are less common. Tetanus in cats and dogs are rare and dogs are less sensitive than cats. Clinically two forms of tetanus have been recognized, i. e. localized and generalized. The available treatment is not specific because the toxin in neuronal cells cannot be accessed by antitoxin antibodies. The aim of the therapy is to: neutralise the unbound neurotoxin, inhibitC. tetanigrowth in the wound, and provide supportive care to mitigate the effects of the neurotoxin. The treatment is difficult with an unclear prognosis.
‘Movement as Disclosive of Being’ Merleau-Ponty: From the Psychology of Gestalt to the Analysis of Movement
Authors: Cantone Damiano , Taddio Luca
Published: October 2020

In this essay we seek to clarify the meaning and theoretical implications of the statement by Merleau-Ponty contained in his 1953 course,Le Monde Sensible et le Monde de l’Expression,according to which movement is ‘revealing of being’. This analysis takes up and comments on chapter 7 ofKoffka’s Principles of Gestalt Psychology(dedicated to the issue of movement) and related experiments in particular. We will show that Merleau-Ponty’s idea of ontology of movement emerges from his examination of several exemplary cases. This method of analysis brings to light an idea of similar phenomenology compatible with an experimental phenomenology.

Published: October 2020

Purpose

Using the metaphor of “unicorn,” we identify the scientific papers and technical patents characterized by the informetric feature of very high citations in the first ten years after publishing, which may provide a new pattern to understand very high impact works in science and technology.

Design/methodology/approach

When we set CT as the total citations of papers or patents in the first ten years after publication, with CT≥ 5,000 for scientific “unicorn” and CT≥ 500 for technical “unicorn,” we have an absolute standard for identifying scientific and technical “unicorn” publications.

Findings

We identify 165 scientific “unicorns” in 14,301,875 WoS papers and 224 technical “unicorns” in 13,728,950 DII patents during 2001–2012. About 50% of “unicorns” belong to biomedicine, in which selected cases are individually discussed. The rare “unicorns” increase following linear model, the fitting data show 95% confidence with the RMSE of scientific “unicorn” is 0.2127 while the RMSE of technical “unicorn” is 0.0923.

Research limitations

A “unicorn” is a pure quantitative consideration without concerning its quality, and “potential unicorns” as CT≤5,000 for papers and CT≤500 for patents are left in future studies.

Practical implications

Scientific and technical “unicorns” provide a new pattern to understand high-impact works in science and technology. The “unicorn” pattern supplies a concise approach to identify very high-impact scientific papers and technical patents.

Originality/value

The “unicorn” pattern supplies a concise approach to identify very high impact scientific papers and technical patents.
Sliding mode controller design for second-order unstable processes with dead-time
Authors: Siddiqui Mohammad Atif , Anwar Md Nishat , Laskar Shahedul Haque
Published: October 2020

A new approach is proposed to design the sliding mode (SM) controller for the unstable second-order plus dead-time (SOPDT) processes. The sliding mode control consists of two control laws ie continuous control law and discontinuous control law. The continuous control law parameters have been derived in terms of unstable SOPDT process parameters using the root locus technique. On the other hand, the parameters of discontinuous control law are tuned by optimizing a performance index using a recently developed metaheuristic search algorithm, namely the grasshopper optimization technique. The performance index is framed to achieve a good trade-off between performance and control efforts. Finally, simulations are conducted to validate the effectiveness of the proposed approach over the other existing techniques. It is observed that the proposed approach is able to deliver better disturbance rejection, minimal control efforts and good setpoint tracking.
De-noising of partial discharge signal using wavelet transform for GIS under HVDC
Authors: Wang Guoming , Hu Han , Tang Min , Gong Jinlong , Wang Yifan , Ji Hong-Keun , Kil Gyung-Suk
Published: October 2020

Detection and analysis of partial discharge (PD) have been regard as the most effective method for condition monitoring and asset management of gas-insulated structures (GIS) in the power system. However, PD detection sensitivity and accuracy are greatly influenced by on-site noise and interference, resulting in failures in PD severity assessment, defect identification or localization. Although de-noising of PD signal under AC was well studied, related investigations under DC have not been carried out. With the rapid development of HVDC technology, it is a new challenge to eliminate noise from PD signal under DC for diagnosis of related power facilities. Therefore, this paper dealt with the discrimination of PD signal based on wavelet transform (WT) techniques for HVDC GIS, aiming to improve the sensitivity and accuracy of insulation diagnosis. Experimental setup was configured to generate PD signal under DC and four types of artificial defects were fabricated to simulate typical insulation defects in GIS. The WT techniques were used to discriminate PD pulse sequences from background noise, amplitude modulation radio interference, non-sinusoidal noise, and switching impulse and the effectiveness was compared with a high-pass filter.

Published: October 2020

The design and implementation of planar multi-way differential power dividers remain a challenge in terms of the compactness and especially, for the achievable characteristic impedance of the quarter-wavelength transformer when considering large number of outputs. In this work, the double-sided parallel stripline is recommended to realize such a power divider with out-of-phase outputs, and explicit design methods are provided. The proposed multi-way power divider was developed without the use of lump elements on a single substrate. For system applications, a prototype operating at 41.6 MHz with 12 pairs of out-of-phase outputs that utilize the microstrip line as the output interfaces was fabricated and examined. At the center frequency of 41.6MHz, the developed prototype measured insertion losses akin to 14.3 dB as compared with the theoretical data of 13.8 dB. The attainable impedance bandwidth ranges from 10 MHz to 80 MHz under a magnitude imbalance of ±0.3 dB. The isolations of the adjacent outputs are about 13.1 dB as compared with the theoretical values of 14.428 dB, and are better than 34 dB for more distant ones. Parameter measurements are in good agreement with the numerical predications, thus demonstrating the realization of the proposed multi-way power divider.

Mycophenolate for the treatment of primary Sjögren’s syndrome
Authors: Chen Weiqian , Lin Jin
Published: October 2020

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease with exocrine gland dysfunction and multi-organ involvement. Currently, there is an increasing trend toward non-steroid therapy for the treatment of autoimmune diseases. Some biological agents or immunosuppressive drugs may be the ideal choices. In real-world practice, as patients have severe systemic complications or organ damage, they will have a bad prognosis even if they are treated with high-dose steroids and strong immunosuppressive drugs. However, if we can start early intervention and prevent progressive development in advance, the patient may have a good prognosis. Mycophenolate is an immunosuppressive drug with minor side effects. Here, we conduct a systemic review and find supporting evidence that patients with pSS benefit from early mycophenolate therapy. Mycophenolate may be the first-line treatment for pSS patients in the future.
Composition and changes in the spontaneous flora of the Wadi El Rayan Ramsar site, Fayoum, Egypt, in the last 20 years
Authors: Afefe Abdelwahab A.
Published: October 2020

Wadi El Rayan is located in Egypt in the Sahara ecoregion the Palearctic ecozone (the world’s largest hot desert). The total area of Wadi El Rayan is 1759km2. The aim of this work was to study the ecosystems, compare species composition, species richness and species diversity of the study sites in the Wadi El Rayan protected area and the distributions of plants in the different landform. The field observations found that there is a low diversity and number of plant species around the lakes, in particular a decline in vegetation cover in accordance with a dramatic decrease in the water level in the lakes compared to earlier studies. The reduction of water levels due to decreased water supply is considered the main threat facing ecosystems and biodiversity in the lake area which requires a continuous survey of flora and measures to be implemented to conserve the natural vegetation in the area. Based on investigations of the spontaneous flora of Wadi El Rayan in 2018, 18 taxa of vascular plants were recorded. This inventory was compared with published records of investigations made in 1998, 2002 and 2014. A total of 18 vascular plant species belonging to 14 families were recorded in the wetland and desert ecosystems around the lakes of Wadi El Rayan. The vegetation mainly consists of sparsely distributed xerophytic and halophytic plants except in the wetland ecosystem around the lakes where it is characterized by some hydrophytic and halophytic plants. The family with the highest number of species was Poaceae followed by Zygophyllaceae. The results showed that a higher number of species was recorded from the Lower Lake (13 species) than the Upper Lake (10 species) and (5 species) for the connecting channel. The most frequently recorded species werePhragmites australis, Tamarix nilotica, Juncus rigidusandAlhagi graecorum: the first two species were the most successful species as they grow in a variety of ecosystems and habitats.
New technique for preparing and reusing agricultural drainage water safely in irrigation
Authors: Ashour Mohamed A. , Aly Tawab E. , Hasan Ahmed E.
Published: October 2020

Not so long ago, due to the great shortage of irrigation water, Egypt on the national level, began to mix (in a certain percentage) raw agricultural drainage water with fresh irrigation water. This mix was for enhancing its quality to be compatible with the proper specifications and standards of irrigation water, for using it safely in the irrigation process, to compensate for the severe shortage of available quantities of irrigation water. In some regions, and local farms, to save their crops farmers were forced to use the drainage water available in the nearby area drains for irrigation due to the problem of insufficient water in the distributary canals. Such use of raw drainage water can cause great harm and has a negative impact on the environment generally, especially on aquatic and agricultural life. Therefore, in this study we aim to introduce an efficient, simple, cheap mobile treatment unit. This new introduced treatment unit can be used locally on farms to solve the problem of insufficient quantities of irrigation water, and also in some cases where the irrigation water, for various reasons, does not reach the ends of some irrigation canals thus causing a serious problem for farmers. The new introduced treatment unit, using some environmentally friendly cheap materials in certain tested quantities and doses, through three designed cylindrical filtration containers connected with each other respectively, succeeded in converting raw contaminated drainage agricultural water into safe water that can be safely and directly used in the irrigation process.
Changes in the quality of a small lowland river in Poland under the influence of pollution and a dam reservoir located in its course
Authors: Hansz Donat , Kowalczewska-Madura Katarzyna
Published: October 2020

The study on a small lowland river was conducted in order to determine changes in water quality under external loading (inflow of treated wastewater, runoff from agricultural areas) and the location of a dam reservoir in its course. The 21 km long River Pogona (Greater Poland, Poland) is a small tributary of the Obra Canal in Kościan. In 2004, in its valley, the Jeżewo Reservoir, with an area of 78 ha, was utilized to supply the flow in the Obra Canal during the dry season and to irrigate agricultural areas. The river is also a receiver of treated sewage from the sewage treatment plant in Karolewo. The research, carried out in 2017 at six sampling stations in its course, showed that the discharge of treated wastewater resulted in an increase in conductivity, concentration of ammonium nitrogen, nitrites and total nitrogen in the waters of the River Pogona. On the other hand, the location of the Jeżewo Reservoir in its course contributed to an increase in water temperature, pH, dissolved oxygen, chlorophyll-a and nitrite concentration in the outflowing river. The results showed that the inflow of treated wastewater from the sewage treatment plant, surface runoff from the catchment area and the Jeżewo Reservoir formed in its course, influenced seasonal and spatial changes in the water quality of the River Pogona.

The polyetiological syndrome of disseminated intravascular coagulation (DIC) is characterized by changes in patients’ hemostasis. The aim of the current research was to elucidate the main factors for the development of DIC syndrome during canine babesiosis, and to assess their correlation level. Dogs included in this study were of various breeds and sex, weighing 10-40 kg and aged 2-7 years. They were separated in two groups (n=50) according to their diagnosis to babesiosis. Oscillometry (blood pressure, pulse rate), vascular-platelet hemostasis, coagulogram, hematological, biochemical (fibrinogen, fibrin degradation product, soluble fibrin-monomer complex) and hemodynamic (circulating blood volume) assessment methods were used. The group of dogs positive on Babesia spp., had clear manifestation of DIC with 5-7% of the erythrocyte population being affected. DIC was manifested by a significant increase in soluble fibrin-monomer complex and fibrin degradation product (p<0.001), hypofibrinogenemia (p<0.001), thrombocytopenia (p<0.001), and an increase in indicators of spontaneous aggregation ability of platelets and red blood cells (p<0.001). Significant hemodynamic disorders were observed: a decrease in circulating blood volume, circulating erythrocytes volume (p<0.05), specific circulating blood volume and hematocrit value (p<0.001). The average blood pressure was reduced (p<0.001), and the Allgöwer’s shock index was increased 2 times (p<0.05). A shock of II degree (medium, subcompensated) was confirmed. Therefore, it can be concluded that acute spontaneous dogs’ babesiosis can be characterized by the occurrence of DIC in a consumption coagulopathy form, and shock of II degree. This condition renders the patients for emergency admission.
Rethinking the historical trajectory of ECE: From the “original sin” in democratization to redemocratization
Authors: Ágh Attila
Published: October 2020

This paper treats East-Central Europe as a region and investigates its common historical trajectory in the last decades. After 30 years of systemic change and 15 years of EU membership, it is high time for the re-evaluation and reconceptualization of the Europeanization and Democratization process in ECE. It is the key to understand the false start as the original sin in democratization and the reasons of ECE divergence from mainstream EU developments in order to prepare the redemocratization process. The progress of the Europeanization and Democratization process in ECE has been widely described in official documents, but for a balanced and complete picture it is necessary to present also the De-Europeanization and De-Democratization process from the very beginning. Basically, after the collapse of the bipolar world order in 1989, the Eastern enlargement was an economic and political necessity as a substantial part of the EU deepening and widening policy. The EU needed the extension of its economic space and political system that had also been pre-programmed in the mission statement of the Rome Treaty. At the same time, the new member states (NMS) needed the “Return to Europe” for their reintegration into the Western world. However, the capacity for this extension was actually missing on both sides, and it has remained so during the last 30 years of systemic change or the 15 years of EU membership. Altogether, this controversial process has produced a colorful picture of successes and failures in all NMS that will be analyzed in an ECE context.
Online Political Communication Research Methods
Authors: Brunnerová Olga , Charvát Jakub
Published: October 2020

The authors explored the research methods of the manifold studies on online political communication published in nine selected scientific journals over an 8-year period stretching from the beginning of 2009 to March 2017 and systematized the results into a comprehensive, methodological, “state-of-the-art” report. The main findings are that the most frequent method of researching online political communication is the quantitative or qualitative content analysis. Still, recurrent is the combination of methodological approaches, where the quantitative and qualitative techniques complement each other. Moreover, the research of political communication in general, but online especially, has become more an interdisciplinary field. Yet the collection and analysis of data from new media and social networks requires more and more advanced expert skills.

Authors: Meng Zhaolei , Zhu Chao , Wang Jian , Wu Wenfei
Published: October 2020

A series of high-entropy mineral catalytic materials were obtained by mixing rare earth tailings containing Fe oxide and rare earth concentrate rich in Ce in Baiyun Obo in different proportions, and by acid-base leaching and microwave roasting. The effects of different proportions of mixed rare earth minerals on the denitrification activity of the samples were analyzed by various techniques, including XRD, EDS and SEM. The mineral phase structure and surface morphology of the catalysts were analyzed. The surface properties of the samples were tested by TPD and XPS methods. The denitrification activity of the sample was simultaneously evaluated and compared in the microreactor. The results show that the denitration efficiency of the active powder is the best when the mixing ratio of rare earth tailings/rare earth concentrate is 1:1, the denitration rate can reach 82%. In summary, different proportions of optimization are extremely effective methods to improve catalyst performance.

Published: October 2020

Introduction: Achieving high positional and dosimetric accuracy in small fields is very challenging due to the imbalance of charged particle equilibrium (CPE), occlusion of the primary radiation source, and overlapping penumbra regions. These factors make the choice of the detector for Stereotactic Radiosurgery (SRS) patient-specific quality assurance (PSQA) difficult. The aim of the study is to compare the suitability of EBT3 Gafchromic film against CC01 pinpoint chamber for the purpose of SRS and stereotactic Radiotherapy (SRT) dose verification.

Material and Method: EBT3 Gafchromic film was calibrated against Treatment Planning System (TPS) doses (1 Gy – 35 Gy). CC01 pinpoint chamber and EBT3 film was used to verify Patient-Specific point doses of 21 intracranial lesions each planned with Static, Dynamic Conformal Arc (DCA), and Volumetric Arc Therapy (VMAT) using Varian TrueBeam Accelerator 6MV Flattening Filter (FF) and 6MV Flattening Filter Free (FFF) beams. The lesion sizes varied from 0.4 cc to 2.9 cc. The lesions were categorized into <1cc, 1cc-2cc and 2cc-3cc.

Results: High variations in measured doses from TPS calculated dose were observed with small lesion volumes irrespective of the dosimeter. As the sizes decreased high uncertainty was observed in ion chamber results. CC01 was observed under-responding to film in small lesion sizes (<1cc), where nearly 50% of results under-responded in comparison with Film results. Film results were more or less consistent for static and DCA plans. Static and DCA plans were consistent passing more than 73% of the plans of the smallest lesion size category. VMAT showed very poor PSQA agreement for all three volumes (32.1% for <1cc, 14.3% for 2cc-3cc and 39.3% for 2cc-3cc). No significant difference was observed between 6MVFF and 6MVFFF beams from the chi-squared test.

Conclusion: EBT3 Film was observed to be a more suitable detector for small lesion sizes less than 1cc, compared to CC01. As the volume increases, the response of CC01 and EBT3 film have no significant difference in performing PSQA for intracranial SRS/SRT. VMAT techniques for intra cranial SRS shows deviation from TPS planned dose for both EBT3 film and CC01 and should not be preferred choice of verification tools.

Published: October 2020

Neonatal hypoglycemia (HG) can cause neurologic damage, epilepsy, mental retardation, behavioral and personality disorders and death. The longest the HG lasts and the greatest the glucose nadir the consequences are more pronounced.

Comorbidities are rather important in development of neurological damage. Hypoxemia and ischemia can cause permanent brain damage. Small for gestational age (SGA), large for gestational age (LGA), intrauterine growth restriction, gestational age bellow the 37th week, low Apgar score, sepsis, children whose mothers have toxemia, diabetes or chorioamnionitis are all newborns with increased HG risk.

Comparing 34 patients with NH and 34 children without NH with similar GA, BW, BL, the Apgar score, we found statistically significant differences in motor and mental development using the Griffith scale. Children with neonatal HG fared significantly worse than those without neonatal HG. Therefore, CBG measurements and early recognition of neonatal HG is of significant importance in preventing motor and mental damage in children. A larger and well-balanced cohort of patients followed for a longer period is also necessary to clarify and discern in detail the importance of neonatal HG and other perinatal factors in neurodevelopmental damage.
LOGFAS Program Paket – Instrument for Optimizing the Planification of Movement and Transport Operations (M&T)
Authors: Pînzariu Sorin
Published: October 2020

Movement and transport planning involves the coordination of a whole complex of influence factors including: the dimensions of the deployed force as well as the logistical support required, the requirements for the time to reach the destination for each structure, the availability of means of transport and their transport capacity, the tactical situation, the terrain conditions, the season and the weather, the availability and maintenance of the communication routes and their occupancy, the existence of threats in the travel strip and their level, the availability of force protection measures, etc. The analysis and application of the measures necessary to improve the influence of these factors on the execution of the mission is a laborious and detailed work with a great need of time for completion. In order to counter the waste of time, as well as the precise and scientific planning of logistics supply and transport support, the North Atlantic Alliance has designed and made available to transport planners in the member countries the package of specialized logistics programmes – LOGFAS (Logistics Functional Area Services).
Public Spending Efficiency in the OECD: Benchmarking Health Care, Education, and General Administration
Authors: Dutu Richard , Sicari Patrizio
Published: October 2020

In many OECD countries, changes in demography and health conditions are putting pressure on public finance. To prevent further expansion of government spending as a percentage of GDP, public spending efficiency will need to be raised. This paper uses data envelopment analysis (DEA) to assess the efficiency of welfare spending (normalized by the working-age population) in a sample of OECD countries around 2012, focussing on health care, secondary education, and general public services. The DEA model has a two input-one output structure, with at least one of the variables representing a composite indicator controlling for country-specific factors (socio-economic environment and lifestyle factors, for example). We find wide dispersion in efficiency measures across OECD countries and provide possible quantified improvements for both output and input efficiency.
Investigation of Metal-based Composites Vibration Properties Using Modal Analysis in Combination with Wavelet Transforms Under Imitation of Operational Loads

Published: October 2020

The present article is dedicated to the study of the vibration properties of metal-based composite materials and the application of the non-destructive testing method. The main modal parameters of the metal-based composites were investigated. For experimental determination of natural frequencies and modes of oscillations, the method of scanning laser Doppler vibrometry was used. For the numerical modal analysis, the finite element method was used. The material model was a layered composite with isotropic linearly elastic layers and metal layers. The task of identifying the material model was considered as the problem of minimising the discrepancy between the calculated natural frequencies and the experimental ones. The developed method can be recommended for the determination of parameters of material models for calculating the modal characteristics of polymer–metal sandwich sheets and metallic mono-materials composite products. Methodology for identifying models of elastic behaviour of polymer–metal composite materials, based on the results of the experimental modal analysis, is presented. Wavelet-based damage detection is also presented as an appropriate approach for the identification of integral conditions of the metal–polymer–metal composite materials. Results of wavelet transform convolutions are presented.
Dual career for students with athlete status at Faculty of economics, University of Ljubljana
Authors: Zovko Vinko , Sember Vedrana
Published: October 2020

Elite athletes invest most of their time and energy in sports training and competitions, so they are often absent from the pedagogical process at university levels of education, which has an impact on the achievement of education. Too often, top-notch athletes are faced with difficulties in building out-of-sports careers, since many have no proper education and necessary experience. It is therefore important that they acquire an education at a time when competing in sport. At Faculty of economics, University of Ljubljana we've developed a system that facilitate education and help students with athlete status to achieve the desired vocational education, despite their intensive involvement in the top sport.
The place and role of leisure time activities and school competitions in physical education and their relations to school sport
Authors: Đukić Verica , Živanović Nenad
Published: October 2020

Timeliness of this topic is not decreased by the fact that it was a subject of discussion on several symposiums from several aspects the authors opted for. This time, the starting point is the fact that physical education teachers, as a professionally responsible experts in physical education, are obliged to contribute to further discussion on following topics: Professional understanding of the essence of conceptual and terminological determination of some organizational forms of work in physical education which are implemented as leisure activities and competitions and their relation to what is called school sport or sport activities in the school. Planned and organized orientation of leisure activities and competition functions towards implementation of the common physical education goal. Compared to the current curricula or sport orientation, what is the scale of educational features of these forms (leisure activities and competitions), which trendier in the practice. To what extent is interest of teachers and students one of the assumptions for such organization of leisure activities and competitions to enable rational and efficient fulfilment of students' leisure time. The First part of this paper presents the statues of leisure activities and competitions in current program concept of physical education in the schools, and aforementioned issues as a subject of professional public permanent interest. As school sport and relation with leisure activities and competition are concerned, some opinions of distinguished experts form higher education institutions were expressed, which were quoted in this paper supporting views of most pedagogists in the school system. Sports and school sport activities similarities and differences represented in the charts. The second part of the paper presents the results of two questionnaires where one is related to the institutional position of sports activities in the school, organization, type and competition system, as well as the rope and obligation of the teacher in implementation of the sports activities in the school. The other questionnaire presents the result of some of the educational values of the competition within the school sport.
Social (in)Justice, or the Condition of Global Capitalism in the Lost Child (2015) by Caryl Phillips
Authors: Frątczak-Dąbrowska Marta
Published: October 2020

The present article is a critical rereading of Caryl Phillips’s latest novel The Lost Child (2015). It looks at the text as both a literary comment on the crisis of today’s global capitalism and as an acute socio-economic analysis of the crisis’ roots and effects. It is being argued that, by placing Wuthering Heights (1847) as an intertext for his contemporary novel and by linking the figure of Heathcliff with African slavery and contemporary poverty, Caryl Phillips aims to emphasise the affinity between the socio-economic conditioning of the nineteenth- and twentieth-century England, as well as between the contemporary and historical experience of economic marginalisation. Thus, he shows global capitalism as a universal experience of long modernity and asks some vital questions about its shape and its future. The following analysis, in line with recent scholarship in the field of postcolonial studies, combines postcolonial criticism with socioeconomic theories and argues that the novel deserves a place in the ongoing debates on the condition of the global economy, social (in)justice and (in)equality, which nowadays become part of the postcolonial literary scholarship.
Change from Above, Language Contact, and Individual Change in Ælfric’s Linguistic Terminology
Authors: Yakovenko Yekaterina
Published: October 2020

The paper focuses on linguistic terminology used by Ælfric (10thc.) in his translation of an anonymous Latin grammar (Excerptiones de arte grammatica anglicе) going back to Priscian and Donatus’ works. Ælfric’s grammatical metalanguage, comprising loan words, semantic loans, loan translations, and periphrastic expressions created for explanatory purposes, is characterized by great diversity. A question arises whether these terms, remaining occasional, made any impact on the language system and can be thus evaluated as change from above.

The paper combines a traditional semantic, morphological, and functional description of Ælfric’s terminology and its consideration within the frame of sociolinguistics; the analysis is supplemented by a cross-linguistic study of Ælfric’s terms with remarks on other Germanic languages. The results achieved enable us to argue that Ælfric’s linguistic terminology, being innovative, displays some features of change from above, arising from language contact and individual change.
