The bioindication importance of the Carabidae communities of Veporské vrchy and Juhoslovanská kotlina
Authors: Langraf Vladimír , Petrovičová Kornélia , David Stanislav , Schlarmannová Janka 
Published: June 2016

Abstract
The Carabidae family (Coleoptera) is used frequently for its bioindication potential to detect the environmental burden. In 2013 and 2014, we studied the correlation of Carabidae on the biotopes of six areas in the Veporské vrchy Mts and the Juhoslovenská kotlina basin by using pitfall traps, Möricke plates and Bambara beetle traps. Out of 432 recorded specimens of beetles (53 species, 15 families), the Carabidae family were the highest number of species and specimens represented, with which we confirmed higher anthropogenic interference and disturbance of ecosystems in the Juhoslovenská kotlina basin. This statistic confirms the presence of the following species typically found on arable land: Anchomenus dorsalis, Calathus fuscipes fuscipes, Harpalus affinis and Pseudoophonus rufipes. The ecosystems in the Veporské vrchy Mts region show less disturbance, and the anthropological impact is smaller, indicated by the presence of the Carabus problematicus species, an important indicator of the conservation of natural forest ecosystems.
Quality assessment of urban trees using growth visual and chlorophyll fluorescence indicators
Authors: Uhrin Peter , Supuka Ján 
Published: June 2016

Abstract
Urbanised landscape represents composed structures of technical and biotic elements where social and economy activities create living space for human society but with strongly changed environment. To dominant characters belong climate changes with increased air temperature, drought and emission load, which has developed wide spectrum of stress factors influencing the urban vegetation. For the assessment of plant growth and adaptation response, we have used Sycamore maple (Acer pseudoplatanus L.) as study model woody plant. In the framework of visual characters, we assessed the following indicators: (a) assimilation organs (leaf necrosis); (b) crown quality (degree of foliage and degree of dead tree crown); (c) trunk and branch quality (mechanical damage, incidence of wood destroying fungus and trunk cavities and callus healing of trunk wounds). Each indicator was assessed in five-point scale, and in the end, the common index of quality was calculated. The quality index achieved 9.33 points in the first and 10.33 in the second evaluation periods in the Nitra city and 2.66 at the both assessed periods in the comparable rural park. In the group of physiological indicators, chlorophyll a fluorescence marker and its Fv/Fm parameter were used. Within three repeating assessment during growing season (June, August and September), the average values reached Fv/Fm = 0.814 in the city and Fv/Fm = 0.829 in rural park. The results confirmed statistical significances between loaded city conditions and relatively clean rural locality. Used markers have shown as appropriate tools for growth response measurements of street trees in a changed urban environment.
Impact of sample size on principal component analysis ordination of an environmental data set: effects on eigenstructure
Authors: Shaukat S. Shahid , Rao Toqeer Ahmed , Khan Moazzam A. 
Published: June 2016

Abstract
In this study, we used bootstrap simulation of a real data set to investigate the impact of sample size (N = 20, 30, 40 and 50) on the eigenvalues and eigenvectors resulting from principal component analysis (PCA). For each sample size, 100 bootstrap samples were drawn from environmental data matrix pertaining to water quality variables (p = 22) of a small data set comprising of 55 samples (stations from where water samples were collected). Because in ecology and environmental sciences the data sets are invariably small owing to high cost of collection and analysis of samples, we restricted our study to relatively small sample sizes. We focused attention on comparison of first 6 eigenvectors and first 10 eigenvalues. Data sets were compared using agglomerative cluster analysis using Ward’s method that does not require any stringent distributional assumptions.
Common therapeutic strategies for prion and Alzheimer’s diseases
Authors: Elezgarai Saioa R. , Biasini Emiliano 
Published: June 2016

Abstract
A number of unexpected pathophysiological connections linking different neurodegenerative diseases have emerged over the past decade. An example is provided by prion and Alzheimer’s diseases. Despite being distinct pathologies, these disorders share several neurotoxic mechanisms, including accumulation of misfolded protein isoforms, stress of the protein synthesis machinery, and activation of a neurotoxic signaling mediated by the cellular prion protein. Here, in addition to reviewing these mechanisms, we will discuss the potential therapeutic interventions for prion and Alzheimer’s diseases that are arising from the comprehension of their common neurodegenerative pathways.
Modern Literature after the 1960s in Korea
Authors: Li Sanggum 
Published: June 2016

Abstract
Since the beginning of the 1990s in Korea, the category and definition of new generation literature have become the topic of heated debate. One may understand this tendency as ‘generation severance’, ‘alienation between social classes’, or the ‘consumption-oriented culture of the masses’. Here, we call the literary youth born in approximately 1960 ‘the new generation’.
In literature, the new generation refers to the appearance of a new culture and way of thinking. This generation passed their childhood in the 1970s and faced no such great difficulties as their parents combating poverty. However, they grew up under the indirect influence of a dark political outlook and suppression. Generally, they have a great affection for the culture produced by mass media.
If we compare their development process with the literary stream in Korea, the 1960s could be defined as the era of literature for independence and strong self-awareness, the 1970s as the era for people, the 1980s as the era for the rights or emancipation of labour, and the 1990s as the era of new generation literature. Meanwhile, the appearance of the ‘Korean Wave’, or so-called ‘Hallyu’, has become one of the most beloved popular cultural phenomena both in Asia and in other countries since the late 1990s.
Common European Framework of Reference for Language (CEFR) and Test of Proficiency in Korean (TOPIK)
Authors: Won Yunhee 
Published: June 2016

Abstract
This paper is an overview of Test of Proficiency in Korean (TOPIK). Test of Proficiency in Korean (TOPIK) is a test to measure and evaluate the Korean language proficiency targeting for overseas Koreans and foreigners who do not speak Korean as their first language. The TOPIK is utilized for studying in Korean universities or taking advantages of employment. Systems of the TOPIK are largely divided into TOPIK I and TOPIK II: TOPIK I is divided into the Beginner 1 and 2; TOPIK II is divided into Intermediate 1, 2, Advanced 1, and 2, all of which are equal to the measure proposed in the European common reference standard. Common European Framework of Reference (CEFR) is equipped with a six-step framework for language proficiency and communicative activities. This system describes knowledge, skills, cultural competence, and regulations of each step-by-step learning skill level for the purpose of communication in the private, public, and occupational areas.
This paper first presents the Common European Framework of Reference (CEFR) that is familiar to Europeans, and compares it with the TOPIK system. First, it compares the TOPIK with the Common European Framework of Reference on the overall system, the assessment method, question types and etc. Also, it briefly examines foreign language education in Korea. Foreign language education in Korea was in abstract level as compared to the Common European Framework of Reference or topic.
As in Europe, Korea also divides the language acquisition into 6 levels. It prepares the evaluation criteria for each level. Criteria and test methods can be understood by comparing the German language test and TOPIK to be carried out in accordance with the Common European Framework of Reference. Test methods and criteria of the German test and TOPIK are similar, but information and instruction for testing showed at the Goethe-Institute is far more detailed than TOPIK in Korea. The problem lies in the absence of speaking test in TOPIK. In order to understand the language proficiency, speaking, listening, reading and writing in all parts should be evaluated; however, there is no speaking test in TOPIK, and it is unfortunate that there is no writing test in the beginner-level test. This is what should be improved in the future.
End User Licence to Open Government Data? A Simulated Penetration Attack on Two Social Survey Datasets
Authors: Elliot Mark , Mackey Elaine , O’Shea Susan , Tudor Caroline , Spicer Keith 
Published: June 2016

Abstract
In the UK, the transparency agenda is forcing data stewardship organisations to review their dissemination policies and to consider whether to release data that is currently only available to a restricted community of researchers under licence as open data. Here we describe the results of a study providing evidence about the risks of such an approach via a simulated attack on two social survey datasets. This is also the first systematic attempt to simulate a jigsaw identification attack (one using a mashup of multiple data sources) on an anonymised dataset. The information that we draw on is collected from multiple online data sources and purchasable commercial data. The results indicate that such an attack against anonymised end user licence (EUL) datasets, if converted into open datasets, is possible and therefore we would recommend that penetration tests should be factored into any decision to make datasets (that are about people) open.
Weight Smoothing for Generalized Linear Models Using a Laplace Prior
Authors: Xia Xi , Elliott Michael R. 
Published: June 2016

Abstract
When analyzing data sampled with unequal inclusion probabilities, correlations between the probability of selection and the sampled data can induce bias if the inclusion probabilities are ignored in the analysis. Weights equal to the inverse of the probability of inclusion are commonly used to correct possible bias. When weights are uncorrelated with the descriptive or model estimators of interest, highly disproportional sample designs resulting in large weights can introduce unnecessary variability, leading to an overall larger mean square error compared to unweighted methods.
We describe an approach we term ‘weight smoothing’ that models the interactions between the weights and the estimators as random effects, reducing the root mean square error (RMSE) by shrinking interactions toward zero when such shrinkage is allowed by the data. This article adapts a flexible Laplace prior distribution for the hierarchical Bayesian model to gain a more robust bias-variance tradeoff than previous approaches using normal priors. Simulation and application suggest that under a linear model setting, weight-smoothing models with Laplace priors yield robust results when weighting is necessary, and provide considerable reduction in RMSE otherwise. In logistic regression models, estimates using weight-smoothing models with Laplace priors are robust, but with less gain in efficiency than in linear regression settings.
Selected aspects related to epidemiology, pathogenesis, immunity, and control of African swine fever
Authors: Woźniakowski Grzegorz , Frączyk Magdalena , Niemczuk Krzysztof , Pejsak Zygmunt 
Published: June 2016

Abstract
African swine fever (ASF) is currently one of the most severe viral infections of domestic pigs, wild boars, and other hosts belonging to Suidae family. ASF is also considered as the most complex and devastating infectious and haemorrhagic disease of swine due to its severe socio-economic impact and transboundary character. ASF it is a notifiable disease and due to the lack of specific treatment and vaccine, the disease can be only limited by the administrative measures comprising wild boar hunting and stamping out of affected pigs. ASF occurred for the first time in Kenya in 1921 while in Europe (Portugal) the virus was detected at the end of the 1950s. In spite of successful eradication of this threat in a number of affected regions, the virus remains endemic in both feral and domestic pigs in Africa and Sardinia. The ‘new era’ of ASF started in 2007 after its re-introduction to Georgia. Following its intensive expansion, the virus spread to other Caucasian countries, including the territory of the Russian Federation. In 2014 the virus reached Ukraine, Belarus, and, consequently, European Union countries: Lithuania, Latvia, Estonia, and Poland. The occurrence of ASF in wild boars and pigs had a severe impact on both epidemiology and economy because of the national and international transport and trade consequences. Up to date, starting from the February 2014, eighty ASF cases in wild boar and three outbreaks in domestic pigs have been diagnosed. Taking into account the diverse rate of spread in Poland, this review aims to present and discuss the current state of knowledge on ASF including its epidemiology, pathology, transmission, and perspectives of control.
Identification of bacterial pathogens and determination of their antibacterial resistance profiles in some cultured fish in Turkey
Authors: Türe Mustafa , Alp Hüseyin 
Published: June 2016

Abstract

Introduction: In the present study, some of the commercial fish farms located in the Black Sea region of Turkey, were screened for bacteria between 2012 and 2014.

Material and Methods: The bacterial agents isolated from fish were identified by classical biochemical tests and the rapid diagnostic tests (API 20 E and API 20 Strep). All strains were further identified by sequencing of the 16S rRNA genes. The strains were also investigated for resistance to different antimicrobials by the disc diffusion method. Antibiotic resistance genes, including tetracycline (B), β-lactam (ampC, blaTEM, blaPSE
), florfenicol (floR), erythromycine (ereA, ereB), sulphonamide (sulI, sulII), and trimethoprim (dhfr1) genes, were determined by the PCR method.

Results:
Vibrio anguillarum, Vibrio fluvialis, Photobacterium damselae subsp. piscicida, Pseudomonas luteola, Lactococcus garvieae, Streptococcus iniae, Aeromonas hydrophila, and Yersinia ruckeri were isolated from marine and freshwater cultured fish. According to the results of disc diffusion, all isolates were sensitive to florfenicol, trimethoprim+sulfamethoxazole, oxitetracycline, and enrofloxacin, and resistant to lincomycin, penicillin G, and amoxicillin. Also, sulI, sulII, and floR resistance genes were detected in the bacteria.

Conclusion: The results of the study open up the opportunity to perform further investigations which could determine the possible role of ARGs in fish pathogens.
Mixed infection zones may be important in the epidemiology of contagious agalactia
Authors: Jafarizadeh Amirreza , Pourbakhsh Seyed Ali , Tadayon Keyvan , Jamshidian Mahmud , Ashtari Abbas 
Published: June 2016

Abstract

Introduction: The current study was designed to detect Mycoplasma agalactiae (Ma), Mycoplasma mycoides subsp. capri (Mmc), Mycoplasma capricolum subsp. capricolum (Mcc) and Mycoplasma putrefaciens (Mp) in sheep and goats with clinical signs consistent with contagious agalactia.

Material and Methods: A total of 299 samples were collected from 55 mixed herds in Azarbaijan-e-Sharghi province, Iran. Samples were examined using PCR and culture methods.

Results: The findings showed that in 40 herds at least one sample was positive by PCR or culture method. Moreover, out of 274 sheep samples, 101 were proved to be positive using the PCR technique and 76 were found positive using the culture method. Out of 25 goat samples, 10 were found positive using PCR and 9 were positive through the culture method. Less than 20% of isolated mycoplasmas were Ma. Ma was detected from almost all studied regions in the province while Mmc, Mcc, and Mp were detected only in a very limited area that was deemed by the research group the mixed infection zone.

Conclusion: In vaccination or eradication projects, it would be more economical to focus on mixed infection zones. Further investigation on mixed infection zones could facilitate better understanding of contagious agalactia epidemiology.

Authors: Mecitoglu Zafer , Senturk Sezgin , Akgul Gulsah , Udum Duygu , Uzabacı Ender , Kasap Sevim , Catik Serkan 
Published: June 2016

Abstract

Introduction: The aim of the study was to investigate changes in the serum levels of adiponectin and TNF-α, as well as insulin sensitivity, and to elucidate the possible relationship among the parameters and negative energy balance during the periparturient period of dairy cows.

Material and Methods: Thirty primiparous Holstein dairy cows were selected for the study. Blood samples were collected from each cow seven days before the expected calving date, on the calving day, and 7, 14, and 21 days after calving. Blood non-esterified fatty acids (NEFA), β-hydroxybutyric acid (BHBA), glucose, insulin, adiponectin, and TNF- α levels were measured. Revised Quantitative Insulin Sensitivity Check Index (rQUICKI) was calculated using data on NEFA, insulin, and glucose concentrations.

Results: When compared to prepartum levels, serum concentration of adiponectin significantly increased on day 21 postpartum. The rQUICKI increased and NEFA levels decreased on day 7 after parturition. Insulin and glucose levels decreased on days 7, 14, and 21 postpartum when compared with prepartum levels. BHBA levels decreased on day 21 and TNF- α concentration also decreased on days 7, 14, and 21 postpartum. Adiponectin levels positively correlated with NEFA during the preparturient period. Negative correlation was detected between adiponectin and rQUICKI on calving day and on 14th day after parturition. TNF- α concentration positively correlated with glucose levels on day 7 prepartum and on 21st day postpartum and with rQUICKI on 21st day postpartum. Negative correlation was detected between adiponectin level and insulin sensitivity.

Conclusion: Based on the results of the study, we concluded that adiponectin could possibly increase insulin sensitivity when blood NEFA concentrations are elevated.
Pharmacokinetic - pharmacodynamic model and ampicillin residue depletion after intramammary administration in cows
Authors: Burmańczuk Artur , Roliński Zbigniew , Kowalski Cezary , Zań Rafał 
Published: June 2016

Abstract

Introduction: The objective of this study was to describe a pharmacokinetic–pharmacodynamic (PK/PD) approach for determination of a rational dosage of ampicillin (AMP) and depletion of the antibiotic residues in milk after intramammary administration to cows.

Material and Methods: The cows came from different farms from the Lublin Province area. They (n = 9) received 5 g of the drug, containing 75 mg of AMP sodium in physiological solution, through a syringe tube by intramammary administration. Following single intramammary administration, the milk samples (5 mL) were collected after 2, 4, 6, 8, 10, 24, 36, 48, and 60 h. The liquid chromatography-mass spectrometry analysis was performed on the Agilent 1200 system connected to an AB Sciex API 4000™ mass spectrometer. The pharmacokinetic analysis of the concentrations of the antibiotic in milk was performed using software Phoenix® WinNonlin® 6.4. Calculations were made in non-compartmental (slopes, highest, amounts, and moments) and compartmental analysis.

Results: The pharmacokinetic characteristics of AMP after intramammary administration indicate rapid elimination of the drug from milk. The mean residence time had a several-fold lower value than the designated elimination half-life and amounts to only 3.4 h. The concentration of the drug in the milk dropped relatively quickly and the process was very dynamic.

Conclusion: The conducted research confirms the rationale of using the PK/PD model in order to verify the dosing regimen for other antibiotic groups and various indicators of the applied PK/PD model.

Published: June 2016

Abstract
The aim of this paper was to test a newly designed algorithm for more accurate calculation of the image displacement of seeding particles when taking measurement using the Particle Image Velocimetry method. The proposed algorithm is based on modification of a classical iterative approach using a three-point subpixel interpolation and method using relative deformation of individual areas for accurate detection of signal peak position. The first part briefly describes the tested algorithm together with the results of the performed synthetic tests. The other part describes the measurement setup and the overall layout of the experiment. Subsequently, a comparison of results of the classical iterative scheme and our designed algorithm is carried out. The conclusion discusses the benefits of the tested algorithm, its advantages and disadvantages.

Authors: Jedrzejewski Roman , Lendzion-Bieluń Zofia , Arabczyk Walerian 
Published: June 2016

Abstract
The iron catalyst precursor promoted with Al2O3, CaO, and Li2O was obtained applying the fusing method. Lithium oxide forms two phases in this iron catalyst: a chemical compound with iron oxide (Li2Fe3O4) and a solid solution with magnetite. The catalyst promoted with lithium oxide was not fully reduced at 773 K, while the catalyst containing potassium was easily reducible at the same conditions. After reduction at 873 K the activity of the catalyst promoted with lithium oxide was 41% higher per surface than the activity of the catalyst promoted with potassium oxide. The concentration of free active sites on the surface of the catalyst containing lithium oxide after full reduction was greater than the concentration of free active sites on the surface of the catalyst promoted with potassium oxide.
Application of Ground Penetrating Radar to Identification of Thickness and Structure of Sediments in Postglacial Lakes, Illustrated with an Example of the Mały Staw Lake (The Karkonosze Mountains)
Authors: Gądek Bogdan , Grabiec Mariusz , Kędzia Stanisław 
Published: June 2016

AbstractThis paper has been aimed at demonstrating the applicability of the ground penetrating radar to acquiring basic information on lake sediments and geomorphological conditions of their deposition in the basin of Mały Staw lake. The lake area is one of the most comprehensively studied part of the Polish part of the Karkonosze Mountains. The application of radar soundings enabled a fast and environmentally friendly verification as well as updating the results of previous research on the thickness and structure of the sediments of this glacial lake. Mały Staw lake is formed at the postglacial depression in the granite bedrock. The bottom of the lake is composed of limnic deposits of the maximum thickness reaching up to 15 m. The postglacial formations occurring below them probably contain a buried moraine of the youngest recessional phase. Solid rock is located about 25 meters beneath the current bottom of the lake.
