Authors: Ciora Radu Adrian , Gifu Daniela , Simion Carmen Mihaela
Published: May 2020

Intuitive user interfaces have been of great concern for GUI developers. The current research, who deals with their designing, faces the term intuitive constantly. The main question is how can the Interface be intuitive? For the moment, the researchers try to provide a very intuitive generic user interface that can be used in a variety of applications. In this paper we provide a solution that can model any applied ontology into a honeycomb menu. The hexagonal shape of the honeycomb has attracted the attention of humans for centuries. As a relevant consequence, the final user can browse any knowledge base very easily with the aid of this interface. Another useful feature is that programmers can take full advantage of semantic web technologies which can tailor results based on any knowledge base that is feed as input, without any need for code change, thus leading towards a panacea system.
Extraction of Benzo[a]pyrene from Moist Snuff with Water or Artificial Saliva (Part 2)
Authors: Moldoveanu Serban C. , Harrison Andrew
Published: May 2020

The present study evaluated the in vitro extraction of benzo[a]pyrene (BaP) from moist snuff into water and into artificial saliva. A similar, previous study evaluated the levels of BaP that remained in the moist snuff after the extraction but did not measure the levels of BaP in the water or saliva extract. The previous study showed that the remaining levels of BaP in the solid material were between 96.3% and 109.6% relative to the initial level of BaP, when the snuff was washed with water and between 99.4% and 108.3% from the initial level of BaP, when the snuff was washed with both saliva and water. Nine moist snuff samples (eight being the same brands as evaluated in the previous study) were analyzed in the present study. Several improvements were made compared to the previous study regarding the extraction conditions. The extraction was performed for 1 h at 37 °C, using a mechanical agitator.

The previous study used a commercially available artificial saliva which had an adjusted pH but did not contain enzymes or salts. This saliva was replaced with complete artificial saliva containing salts, mucin and enzymes. The results indicated that the level of BaP extracted in 100 mL water from 5 g of moist snuff at 37 °C ranged between 1.0% and 1.7% of the initial level present in tobacco. For artificial saliva, the extracted level of BaP was between 2% and 3.9% from the initial level, depending on the moist snuff brand. Although the BaP level extracted from the moist snuff with artificial saliva remained very low, the surfactant character of artificial saliva increased BaP extraction relative to water by a factor of approximately two. This study supports the previous reported finding that the vast majority of BaP in moist snuff is not extracted in water or artificial saliva.

Innovated Altman’s Model as a Predictor of Malfunctioning of Small and Medium-Sized Businesses in Bosnia and Herzegovina
Authors: Vidimlić Selma
Published: May 2020

The research was conducted with the aim of finding a model that best predicts the financial success or failure of the company. On the sample of 392 SME in Bosnia and Herzegovina, testing possibilities using the innovated Altman’s model for prediction of financial difficulties of the enterprise was carried out. The financial statements from the end of the year 2014 of these companies were reviewed. The sample was divided into two groups: companies that had blocked transaction accounts during 2015 and 2016 and those companies that did not have blocked transaction accounts during this period. Testing has shown that the Altman’s model may, but with limited capability, be used to predict the disruption of small and medium-sized businesses in Bosnia and Herzegovina. The paper presents the facts that affect the business of SME in Bosnia and Herzegovina, and way they influence selection and, possibly, other predictors of non-business operations

Authors: Savić Jovana , Veselinović Nevena
Published: May 2020

The economic crisis and the emergence of an increasing number of competitors in the banking sector have led to the need for banks to better understand their clients and to work more closely together with them. The basis of survival and profitable business of banks is the achievement of high quality offer that is the asset for developing long-term relationships. The aim of the paper is to determine the effects of the banking services quality dimensions on satisfaction and loyalty of clients using modified SERVQUAL model. The main research question is to examine which dimensions of banking services quality have an effect on the satisfaction and loyalty of clients, what is the nature and the intensity of this impact. For the purpose of measuring clients’ attitudes regarding banking services quality, the survey method, questionnaire technique was applied. The questionnaire was distributed to clients of banks operating in the territory of Kragujevac, Central Serbia, in the period from September to October, 2018. Simple random sample technique for sampling was applied. The analysis was conducted by processing the primary data in statistical software SPSS where several statistical analyses were conducted. Based on multiple regression analysis, it came to the result that the strongest influence on clients’ satisfaction has variable empathy and the weakest variable tangibility, while variable reliability has no influence. On the other hand, clients’ loyalty is most strongly influenced by variable responsiveness while the weakest influence, as well as on satisfaction, has variable tangibility. The paper points to the significance of improving banking services quality in order to achieve higher level of satisfaction and long-term clients’ loyalty, which is particularly important when it comes to dimensions that have weak or no influence on the observed aspects of consumer behaviour.

Authors: Tkach Viktor , Bondar Oleksandr , Rumiantsev Maksym
Published: May 2020

The aim of the study was to analyze the origin of oak stands within the catchments of the Vorskla’s tributaries and to describe their state. Covering 60,900 ha, pedunculate oak (Quercus robur L.) stands prevail and cover 51.1% of the total forest area of 119,200 ha in the catchment areas of the River Vorskla’s tributaries. The way oak stands are distributed in regards to trophotopes points at favourable conditions for their growth, as 81.7% of the area is a fresh fertile oak forest site type. Forest stands aged 41–80 years (39.8 % of the total area) and 81–120 years (50.4%) are prevailing. Natural oak stands cover almost 66.5% and planted ones grow at 33.5%. Distribution of oak stands in regards to the functional categories of forests shows a significant predominance of the protective forests. They cover 46.6% of the total area. The commercial forests cover 23.0%, the recreational ones make 18.8% and the forests with conservational, academic, historical and cultural purpose cover 11.6 %. Distribution patterns of oak forests in the catchments of the River Vorskla’s tributaries should be considered in the forest management in order to conserve their biodiversity and enhancing the performance of important environmental, protective, recreational and other functions. The article contains results of the study on the natural regeneration of Quercus robur and other wood species under the canopy of oak stands and on felling sites. The further research perspectives are a thorough study of the stand characteristics and the typological structure of forests in terms of certain wood species in the catchments of rivers all over Ukraine. It will help developing principles for the catchment and landscape zonation.
Relationships Between the Spread of Pathogens and the Migratory Connectivity of European Wild Birds
Authors: Korytár Ľ. , Prokeš M. , Ondrejková A. , Zemanová S.
Published: May 2020

Among emerging infectious diseases, 75 % are zoonotic. Migratory birds are important to public health because they carry emerging zoonotic pathogens or infected arthropod vectors. Disease is an important factor in the evolution of avian migrations and patterns of migratory connectivity. Research suggests that pathogen densities and diseases may influence the evolution of migratory behaviour. During the annual life cycle, European migratory birds spend: 2—4 months at the breeding locality, approximately 6 months on the wintering grounds, and several months (3 and more) on migration routes. There are many factors which determine when and where an outbreak of a disease may occur. Therefore, a complete understanding of the avian migratory systems has a high priority in the prevention of future outbreaks.

Authors: Yevstafieva V. , Yeresko V. , Melnychuk V. , Bakhur T.
Published: May 2020

New data about the fauna of nematodes of Baruscapillaria genus have been obtained which show that they parasitize domestic geese in the Poltava region of the Ukraine. It has been established that the species composition of Capillariidae is represented by two species—B. anseris (Madsen, 1945, Moravec, 1982) and B. obsignata (Madsen, 1945, Moravec, 1982). For the first time in the Ukraine, parasitisation with non-specific geese species of Capillariidae family, B. obsignata, have been substantiated. It was found that capillariosis of geese was more frequent in the co-invasions of the birds’ digestive channel; the prevalence of invasion was 41.97 %. According to the results of helminthological dissection and identification of isolated pathogens, 40 varieties of co-invasions were found, where nematodes of the Baruscapillaria genus were combined with cestodes of two species: Drepanidotaenia lanceolata (Bloch, 1782) and Tschertkovilepis setigera (Froehlich, 1789), as well as with nematodes of four other species: Аmidostomum anseris (Zeder, 1800), Trichostrongylus tenuis (Mehlis, 1846), Heterakis gallinarum (Schrank, 1788) and Heterakis dispar (Schrank, 1790). Most often, we recorded capillariosis as a part of two- (prevalence—17.75 %) and three-component (11.75 %) co-invasions, and the main coexisting helminths of Capillariidae from Baruscapillaria genus were nematodes A. anseris (prevalence 22.78 %) and H. dispar (14.15 %).

Authors: Iliev P. T. , Kirkova Z. T. , Tonev A. S.
Published: May 2020

The present work was designed to evaluate the prevalence of gastrointestinal parasites and some vector-borne pathogens in dogs in Bulgaria. A total of 172 owned dogs, keeping outside, were included in the study. Fecal samples were examined using standard flotation and sedimentation methods. Blood samples were processed by Knott’s technique, SNAP™ 4Dx Plus Test (IDEXX) and Angio Detect™ Test (IDEXX). The overall prevalence of gastrointestinal parasites was 64.5%. Eggs of hookworms (Ancylostoma sp. and Uncinaria sp.) were the most frequently detected (54.1%), followed by Trichuris vulpis (15.1%), Capillaria sp. (11.0%), Toxocara canis (6.4%), Cystoisospora sp. (4.1%), Sarcocystis sp. (2.3%), Toxascaris leonina (1.7%), Taenia sp. (1.2%) and Linguatula serrata (0.6%). In addition, hookworms were the most commonly involved in the cases of single infection (20.3%). Combinations between Capillaria sp./hookworms and T. vulpis/hookworms were the most common co-infections (4.1% and 2.9%, respectively). Blood samples revealed the presence of antibodies against Ehrlichia sp. (13.4%), Anaplasma sp. (13.4%) and Borrelia burgdorferi (1.7%). Antigens of Dirofilaria immitis and Angiostrongylus vasorum were detected in 10.5% and 0.6% of the samples tested, respectively. Microfilariae of Dirofilaria repens were found in 5.8% of the blood samples. Additionally, the prevalence of D. immitis and Ehrlichia sp. was significantly higher in adult than in young dogs (p<0.05). In contrast, the gender was not considered as a risk factor contributing to the occurrence of infections.
Effect of Actual and Perceived Violence on Internal Migration: Evidence from Mexico’s Drug War
Authors: Fernandez-Dominguez Amilcar Orlian
Published: May 2020

According to the Organisation for Economic Co-operation and Development (OECD), violence should be considered by examining both actual and perceived crime. However, the studies related to violence and internal migration under the Mexican drug war episode focus only on one aspect of violence (perception or actual), so their conclusions rely mostly on limited evidence. This article complements previous work by examining the effects of both perceived and actual violence on interstate migration through estimation of a gravity model along three 5-year periods spanning from 2000 to 2015. Using the methods of generalized maximum entropy (to account for endogeneity) and the Blinder–Oaxaca decomposition, the results show that actual violence (measured by homicide rates) does affect migration, but perceived violence explains a greater proportion of higher average migration after 2005. Since this proportion increased after 2010 and actual violence, the results suggest that there was some adaptation to the new levels of violence in the period 2010–2015.
Evolutionary Algorithm with a Configurable Search Mechanism
Authors: Łapa Krystian , Cpałka Krzysztof , Laskowski Łukasz , Cader Andrzej , Zeng Zhigang
Published: May 2020

In this paper, we propose a new population-based evolutionary algorithm that automatically configures the used search mechanism during its operation, which consists in choosing for each individual of the population a single evolutionary operator from the pool. The pool of operators comes from various evolutionary algorithms. With this idea, a flexible balance between exploration and exploitation of the problem domain can be achieved. The approach proposed in this paper might offer an inspirational alternative in creating evolutionary algorithms and their modifications. Moreover, different strategies for mutating those parts of individuals that encode the used search operators are also taken into account. The effectiveness of the proposed algorithm has been tested using typical benchmarks used to test evolutionary algorithms.
Spontaneous Sublingual Haematoma in a 90-year Old Patient: A Complication of Direct Oral Anticoagulants
Authors: Cnossen Johannes Daniël , Schoonderbeek Jeannette Fenna , Muller Maaike
Published: May 2020

Sublingual haematoma is a rare complication of anticoagulants and can be life-threatening. As the number of prescribed anticoagulants is increasing, the incidence of complications of these drugs will continue to increase. A report of a sublingual haematoma in an elderly patient with chronic atrial fibrillation treated with edoxban (Lixiana ©, Daiichi Sankyo Europe GmbH, München, Germany) is reported. A 90-year male presented at the emergency department with an obstructed upper airway due to a sublingual haematoma. The patient received tranexamic acid, prothrombin complex, and fresh frozen plasma. After fiberoptic nasal intubation, the patient was monitored in the intensive care unit. After four days, the patient was extubated, and after six days, the swelling resolved completely. Complications of anticoagulants are rare but can be life-threatening. Recognition of an endangered airway and reversing the effects of the anticoagulant are essential. Surgical evacuation of the haematoma could be considered but is not necessary.

Authors: Gozar Liliana , Toma Daniela , Făgărășan Amalia , Miklósi Dorottya , Togănel Rodica
Published: May 2020

Congenital aortic stenosis (AS) occurs in around 0.2–0.5% of newborns, and its clinical severity is quite variable. Some of the newborns with AS require urgent medical care: prostaglandin infusion, balloon aortic valvuloplasty, or surgical intervention. Despite having a severe clinical evolution in neonates, the prenatal diagnosis of congenital AS is quite low. We present the case of a fetus with critical AS, who had been prenatally diagnosed at 35 weeks of gestation, via fetal cardiac ultra-sound. The echocardiographic parameters revealed a severely depressed left ventricular systolic function, with dilated chambers, and a severe aortic stenosis. Offline speckle-tracking analysis was performed in order to aid in deciding the optimal methods and timing of delivery. Left ventricular analysis revealed a severely impaired global longitudinal strain of 2.1%, left ventricular ejection fraction 18.4%, increased LV volumes, while the right ventricular function was only mildly depressed. Therefore, the decision was to delay the premature delivery, and the fetus was born at a gestational age of 38 weeks, in a hospital with a neonatal cardiovascular surgery department. The patient had undergone surgical repair of the cardiac anomaly at 3 days after birth.
Brugada Syndrome – Report of Familial Occurrence Diagnosed in the Emergency Department
Authors: Fazel Mojtaba , Hamidi Fatemeh , Afshari Elham
Published: May 2020

Introduction: Brugada syndrome represents the clinical manifestation of a rare disease with genetic etiology. The syndrome is characterized by ventricular dysrhythmias associated with syncope or sudden cardiac death in the lack of any structural cardiac disease. The diagnosis of Brugada syndrome is established if a type 1 electrocardiographic (ECG) pattern of ST-segment and QRS morphology is present, in association with certain clinical manifestations and/or familial history.

Case presentation: A 31-year-old male patient, without any medical history, presented in the emergency department (ED) of a clinical center. His only complaints consisted in palpitations, chest discomfort, and emotional stress related to the recent death of his wife. Earlier on the same day, his wife, a 25-year-old female was brought via emergency medical services (EMS) to the ED after presenting ventricular fibrillation. The female patient presented a long term history of chest pain and one year prior to this episode she presented idiopathic ventricular fibrillation, for which she had undergone implantation of an automated cardioverter defibrillator. As the couple were cousins, the EMS specialist suspected the presence of a familial cardiac disorder. The electrocardiogram of the male patient revealed a coved-type ST-segment elevation of 4 mm in leads V1–V3 compatible with type 1 Brugada syndrome.

Conclusion: In case of Brugada syndrome, a genetic disorder associated with increased risk of SCD, the patient's first-degree relatives should be investigated as well, in order to identify the presence of the syndrome and to prevent SCD. As the sole established effective therapeutic measure for patients diagnosed with Brugada syndrome, ICD implantation should be considered in order to decrease the risk of syncope and SCD. This case is particular because a rare disease with familial etiology was identified in both husband and wife, who were cousins.
Implementation of the orthodoxy test as a validity check on experimental field emission data
Authors: Allaham Mohammad M. , Forbes Richard G. , Knápek Alexandr , Mousa Marwan S.
Published: May 2020

In field electron emission (FE) studies, it is important to check and analyse the quality and validity of experimental current-voltage data, which is usually plotted in one of a small number of standard forms. These include the so-called Fowler-Nordheim (FN), Millikan-Lauritsen (ML) and Murphy-Good (MG) plots. The Field emission orthodoxy test is a simple quantitative test that aims to check for the reasonableness of the values of the parameter “scaled field” that can be extracted from these plots. This is done in order to establish whether characterization parameters extracted from the plot will be reliable or, alternatively, likely to be spurious. This paper summarises the theory behind the orthodoxy test, for each of the plot forms, and confirms that it is easy to apply it to the newly developed MG plot. A simple, new, accessible web application has been developed that extracts scaled-field values from any of these three plot forms, and tests for lack of field emission orthodoxy.

Published: May 2020

We present the design of a tri-band E-shaped printed antenna with C-shaped slots. A Rectangular patch etched with an n-shaped slot is added at the back of the substrate to enhance the bandwidth and the return losses of the resonant bands - particularly, that of the second band. Our antenna is designed to operate at 1.51/2. 46/6.11 GHz. As can be observed from the experimental results, it has 10 dB bandwidths of 157 MHz (1.416 to 1.573 GHz) 358 MHz (2.221 to 2.579 GHz) and 367 MHz (5. 918 – 6. 285 GHz) The first two bands cover the LTE, Bluetooth, IEEE 802.15.4 ZigBee and IEEE 802.11 WLAN applications. The third resonant band covers the unlicensed 6 GHz band which is widely implemented in wireless power transmission, as well as, RFID and satellite communications. In order to ease wireless congestion, the 6 GHz band is also currently being considered by the FCC to be opened up for the use of WiFi applications. Our antenna is fabricated on a single-sided FR4-epoxy, and it constitutes a compact size of 34 mm × 36 mm × 1.6 mm or 0.17λ × 0.18λ times0.0081λ, (based on the 1.51 GHz lowest resonant frequency) The antenna exhibits omnidirectional radiation patterns at the three resonant bands.
Evolution of Political and Security Relationship between the Republic of Poland and the United States of America in the years 1999–2019
Authors: Kozlowski Grzegorz
Published: May 2020

The article discusses the evolution of political and security cooperation between the Republic of Poland and the United States of America in the years 1999–2019. It argues that this relationship has been strengthened over the past several years to an unprecedented level, as reflected by the following: (a) permanent presence of US troops and facilities on the territory of the Republic of Poland; (b) significant reinforcement of energy cooperation that would contribute to the security of the Central and Eastern European (CEE) region; (c) development of a high-level strategic dialogue; and (d) successful widening of the mutual scope of soft security collaboration, including economic, digital and people-to-people aspects. In this article, I try to answer the following questions: what are the reasons of upgrading Poland–US political and security relations? What was the process shaping US– Poland relationship during 1999–2019? What are the priorities for both sides in this cooperation? I suggest that the past 20 years of Polish–American relationship can be divided into three stages: (a) between Poland’s accession to North Atlantic Treaty Organization (NATO) and Russian aggression towards Ukraine (1999–2014); (b) between the NATO Summit in Newport and the swearing in of Donald Trump as President of the United States (2014–2017); and (c) then onwards (2017/2018–).

The role of the human factor in aviation is a critical element for the safety of flight operations. It is described by methods such as SHELL and BowTie, which propose solutions to minimize the risk of occurrence of aviation events. The work presents the development of these concepts by introducing the method of testing the predisposition of airport staff using a specialized system which is the Polipsychograph - a system dedicated to designing and carrying out psychological tasks testing human mental, cognitive and motor skills in connection with the assessment of his professional capabilities. The work contains the results of 40 tests performed on employees dealing with airport ground handling on a daily basis. Research has shown that the employee’s predisposition depends on the quality of work entrusted to him. The paper presents a method of assessing the psychophysical predisposition of an employee allowing him to be directed to work corresponding to his qualifications.

Authors: Porco Pierluigi , Przysowa Radoslaw , Botto Daniele
Published: May 2020

Composite fan blades are more and more common both in aviation and ground applications. This work aims to characterize the vibration parameters of plastic blades installed in a wind tunnel fan by a non-contact method, namely blade tip timing (BTT). Blade dynamics was predicted with finite element modelling (FEM) and confirmed experimentally by tip timing measurements and analysis of data. BTT results were acquired and compared in two different configurations. A good agreement between predicted and measured frequency values was obtained for the fundamental mode. Significant differences were observed for the second and third modes due to material anisotropy and contact effects which could not be modelled because necessary material data were unavailable.

The socioeconomic performance of small and mediumsized industrial towns: Slovenian perspectives
Authors: Bole David , Kozina Jani , Tiran Jernej
Published: May 2020

The socioeconomic performance of industrial small and medium-sized towns (SMSTs) in comparison to that of non-industrial SMSTs, is subject to evaluation in this paper, to see if the presence of industry has adverse effects on socioeconomic factors. We studied 32 variables accounting for dimensions of socioeconomic performance in Slovenian SMSTs and conducted various statistical tests. We found only minor differences between the two groups, pertaining mainly to some elements of economic structure and demography, and some mixed relations of industrial employment and socioeconomic performance. The results demonstrate that industrial SMSTs should not be labelled automatically as ‘disadvantaged’. We discuss why our results differ from general research expectations in the literature: in the local context, we outline the “egalitarian syndrome” and policies of polycentric spatial development; in the global context, we discuss the “failed tertiarisation effect” and the differences between post-socialist and “Western” countries. We conclude by proposing that research should be re-oriented towards the more place-sensitive issues of industrial towns across Europe.
Changes in urban transport behaviours and spatial mobility resulting from the introduction of statutory Sunday retail restrictions: A case study of Lodz, Poland
Authors: Borowska-Stefańska Marta , Kowalski Michał , Wiśniewski Szymon
Published: May 2020

The impact of statutory Sunday retail restrictions on the transport behaviours of people living in the Polish post-socialist city of Lodz is investigated in this article. One carrier of information on journeys undertaken in the city is data from induction loops – a part of the city’s Intelligent Transportation System (ITS). The second source of data is a two-stage questionnaire survey (concerning trading and non-trading Sundays) of the city’s inhabitants, aimed at defining any changes in their transport behaviours with reference to the introduction of retail restrictions. The research was conducted to assess the way in which the new statutory restrictions affect transport behaviour discharged after the political transformation. The results of the research conducted on the transport behaviours of Lodz residents indicate that the majority of their transport behaviours clearly depend on whether a given Sunday is a trading or non-trading day. The traffic load of the urban road network (perceived as the manifestation of residents’ spatial mobility) is characterised by a distinct changeability due to the legislative restrictions related to Sunday trading. There is both a time (daily and hourly) differentiation of traffic flows and a spatial changeability of the load in the urban space, when a comparative analysis is conducted of the results of observations made in the weeks preceding trading and non-trading Sundays. The study also demonstrates that the time previously devoted to Sunday shopping is currently spent not only at home, but also allocated to new (and until now unperformed) activities that often require travelling.
Direct formation of ZnO nanorods by hydrothermal process: study on its optical properties and electron transport

Published: May 2020

We report a new direct fabrication of the ZnO nanorods (NR) by hydrothermal method, in which the preparation of seed layer is eliminated. We show that the tuning of initial temperature rate during the hydrothermal process plays a key role in the structural modification of the ZnO NR. A highly oriented ZnO NR is successfully fabricated by using a low rate of initial temperature. The increase of optical absorption and electron transport was obtained by reducing the diameter and increasing distribution of the ZnO NR on the substrate. Interestingly, an additional absorption from the defects is obtained in the system, which plays an important role in expanding the optical absorption. Our system will provide a favourable characteristic for developing the high-performance optoelectronic devices with high optical absorption and high electron transport.

Published: May 2020

Polyurethane (PU) is a polymer widely used in the biomedical field with excellent mechanical properties and good biocompatibility. However, it usually exhibits poor antibacterial properties for practical applications. Efforts are needed to improve the antibacterial activities of PU films for broader application prospect and added application values. In the present work, two PU films, TDI-P(E-co-T) and TDI-N-100-P(E-co-T), were prepared. Silver nanoparticles (AgNPs) were composited into the TDI-N-100-P(E-co-T) film for better mechanical properties and antibacterial activities, and resultant PU/AgNPs composite film was systematically characterized and studied. The as-prepared PU/AgNPs composite film exhibits much better antibacterial properties than the traditional PU membrane, exhibiting broader application prospect.
Free radical scavenging ability of sodium lignosulfonate and its application in food grade polypropylene
Authors: Musajian Dilhumar , Hasan Gvlmira , He Mingyu , Yimit Mamatjan
Published: May 2020

Sodium lignosulfonate (SL) was prepared from waste of cotton lignin (CL) through hydrothermal reaction method. Orthogonal experiment was designed with value of OIT as objective function. Polypropylene (PP) is a polymer produced by the addition polymerization of propylene. It is a white waxy material with a transparent and light appearance, which is widely used in food and pharmaceutical packaging. The results of GPC and TG analysis revealed that SL has stable thermal properties, which means that SL has the potential to be an antioxidant for PP materials. In addition, the scavenging effects of CL and SL were studied. The obtained results exhibited that the SL can obviously increase the scavenging effect on free radicals and it is a kind of new synthetic antioxidant with antioxidant property, which could effectively delay the oxidation of PP. Subsequent rheological experiments proved that the SL/PP sample can improve the heat-resistant oxygen performance of PP under the thermal oxygen shearing environment. Combined with the effect of SL on the mechanical properties of PP before aging, SL has a stabilizing effect on PP thermal oxygen aging.

Classification algorithms/tools become more and more powerful and pervasive. Yet, for some use cases, it is necessary to be able to protect data privacy while benefiting from the functionalities they provide. Among the tools that may be used to ensure such privacy, we are focusing in this paper on functional encryption. These relatively new cryptographic primitives enable the evaluation of functions over encrypted inputs, outputting cleartext results. Theoretically, this property makes them well-suited to process classification over encrypted data in a privacy by design’ rationale, enabling to perform the classification algorithm over encrypted inputs (i.e. without knowing the inputs) while only getting the input classes as a result in the clear.

In this paper, we study the security and privacy issues of classifiers using today practical functional encryption schemes. We provide an analysis of the information leakage about the input data that are processed in the encrypted domain with state-of-the-art functional encryption schemes. This study, based on experiments ran on MNIST and Census Income datasets, shows that neural networks are able to partially recover information that should have been kept secret. Hence, great care should be taken when using the currently available functional encryption schemes to build privacy-preserving classification services. It should be emphasized that this work does not attack the cryptographic security of functional encryption schemes, it rather warns the community against the fact that they should be used with caution for some use cases and that the current state-ofthe-art may lead to some operational weaknesses that could be mitigated in the future once more powerful functional encryption schemes are available.
Enhanced Performance and Privacy for TLS over TCP Fast Open
Authors: Sy Erik , Mueller Tobias , Burkert Christian , Federrath Hannes , Fischer Mathias

Small TCP flows make up the majority of web flows. For them, the TCP three-way handshake induces significant delay overhead. The TCP Fast Open (TFO) protocol can significantly decrease this delay via zero round-trip time (0-RTT) handshakes for all TCP handshakes that follow a full initial handshake to the same host. However, this comes at the cost of privacy limitations and also has some performance limitations. In this paper, we investigate the TFP deployment on popular websites and browsers. We found that a client revisiting a web site for the first time fails to use an abbreviated TFO handshake in 40% of all cases due to web server load-balancing using multiple IP addresses. Our analysis further reveals significant privacy problems of the protocol design and implementation. Network-based attackers and online trackers can exploit TFO to track the online activities of users. As a countermeasure, we introduce a novel protocol called TCP Fast Open Privacy (FOP). TCP FOP prevents tracking by network attackers and impedes third-party tracking, while still allowing 0-RTT handshakes as in TFO. As a proof-of-concept, we have implemented the proposed protocol for the Linux kernel and a TLS library. Our measurements indicate that TCP FOP outperforms TLS over TFO when websites are served from multiple IP addresses.
Mind the Gap: Ceremonies for Applied Secret Sharing

Secret sharing schemes are desirable across a variety of real-world settings due to the security and privacy properties they can provide, such as availability and separation of privilege. However, transitioning secret sharing schemes from theoretical research to practical use must account for gaps in achieving these properties that arise due to the realities of concrete implementations, threat models, and use cases. We present a formalization and analysis, using Ellison’s notion of ceremonies, that demonstrates how simple variations in use cases of secret sharing schemes result in the potential loss of some security properties, a result that cannot be derived from the analysis of the underlying cryptographic protocol alone. Our framework accounts for such variations in the design and analysis of secret sharing implementations by presenting a more detailed user-focused process and defining previously overlooked assumptions about user roles and actions within the scheme to support analysis when designing such ceremonies. We identify existing mechanisms that, when applied to an appropriate implementation, close the security gaps we identified. We present our implementation including these mechanisms and a corresponding security assessment using our framework.

Estimating the level of competency training at the end of a university programme aims, in the competency-based learning, at a certification of the training’s outcomes. This research wishes to evaluate the degree of specific competency training for a Bachelor programme in music organized by the Gheorghe Dima National Academy of Music from Cluj-Napoca in different forms of learning, namely full-time and distance learning. By means of a questionnaire which measures the appreciation of students on a scale from 1 to 5 we interviewed 60 students who measured their own professional training based on the competencies approved on a national level for music as major subject. We analyzed descriptors characteristic of certain development levels of the key competencies for three specific content areas: the theoretical, methodological, and artistic areas. The main findings of the research, following a comparative analysis of the implementation of programme-specific competencies, reveal superior outcomes in the case of distance students in the development of competencies belonging to the field of performance, the practical activity carried out during the learning process, at their place of work and through participation in artistic productions, thus motivating the students’ interest in acquiring and improving certain specific skills and abilities. The theoretical knowledge and consolidation of the musical language represent the priorities of the full-time students and, by means of a statistical comparison, we highlighted different answers for the results of the questionnaire meant for the assimilation of competencies for each of the descriptors analyzed in this study.
18. Technical and Interpretive Considerations inthe Third Sonata for Violin and Piano, OP. 45by Edvard Grieg
Authors: Ioniță Raluca Dobre
Published: May 2020

Considered one of the founders of the Norwegian national music culture, Grieg sought to transpose into his music the grandeur of nature, the simplicity of people and their lives, the richness of fantasy and mythological stories. Edvard Grieg retains in his music essential elements of Norwegian folklore, which he uses in his own language. The third Sonata for violin and piano, op. 45 differs from the other two sonatas created previously, both by the dramatic character of the thematic material, as well as by the massive dimensions and the structure of the form that approaches the classical pattern. Starting with this Sonata, Grieg definitely crystallizes his style in the field of chamber music, revealing a mature language of dramatic essence, in which we find rich and inventive rhythmic and melodic structures, plastic harmonies and bold dissonances, picturesque timbre effects that capture the atmosphere and the specific Norwegian color.
1. Features of Some Cultures of the Ceramics of the Early Hallstatt Complex with Incised and Engraved Ceramics on the Territory of Romania

The present study will only refer to the Early Hallstatt, Ha A-B, the beginning of the first Iron Age brought important transformations recorded in ceramics, once the production forces started to develop because of the spreading of iron metallurgy. In a time when ceramics suffers major transformations regarding forms and decor – we are talking here about the first period of Hallstatt (the early one) – the Hallstatt Complex with incised and engraved ceramics completes the image of pottery at that time, together with the other great cultural unity (the horizon with fluted ceramics).
1. Methods of Individual Creativity Stimulation
Authors: Rusu Marinela
Published: May 2020

The concept of communication is a notorious one but at the same time, difficult to define precisely. However, many researchers recognize a number of attributes as easy to define and interpret. In this paper we will carry out a detailed analysis of each of these components of the basic model of communication (Hargie, O., Dickson, D. 2004, Dickson, 2001, Hargie and Tourish, 1999, Dickson et al., 1997). Interpersonal communication is a transactional, intentional, multidimensional, irreversible and (possibly) inevitable process. It is strictly determined by factors such as the situational context of the person, cognitive, affective or temporal elements. The participants in the communication carry and reflect the whole personal “baggage”, of which the accumulated knowledge and experiences, motives, interests, values, emotions, attitudes, expectations and personal dispositions are part. To these are added the self-image, the beliefs about one’s own abilities to succeed (self-efficacy). All these elements will determine the kind of meetings planned, the objectives selected, the persistence in achieving them, as well as the anticipation of possible rewards. Effective interpersonal involvement can be interpreted in terms of concepts such as: person-context, goals, mediation processes, responses, feedback and perception. We can think of spatial, temporal, relational and sometimes organizational frameworks in which the communication process is incorporated. The personal characteristics of the participants, together with the specifics of the situation, act to model the interaction. Also, the objectives pursued are determined by personal and situational factors. The plans and strategies for their realization come from the mediation processes and the strategy adopted accordingly, is reflected in the manifested answers, in behavioral and decision choices.

Published: May 2020

In this article, concepts such as “creativity” and “artistic creativity”, based on the ideas of a number of famous scholars, are dealt with. The concept of “creativity” is defined according to the aspiration of an artistic person to self-expression. Speaking about the structure and the components of the creative process, we have identified the factors that enhance the development of the creative abilities of the students from the pedagogic-artistic specialties in the process of designing the didactic-artistic approach. It is also reflected in the diversity of these factors: psychological, pedagogical, didactic, artistic. In conclusion, the emphasis is on the fact that self-expression in artistic creativity is the individual’s need, and need is classified as aesthetic.
Case Study: Range of Bush Plantings in Gardens Designed by Landscape Architect Josef Vaněk
Authors: Prokeš R.
Published: May 2020

Identification of the original planting range used and its specific applications in the objects of historical landscape works can significantly help in art monuments reconstruction. Concerning the work of interwar Czech landscape architects, the issue of a perennial flower bed has been intensively studied. By the tree and bush floors, the problem is more complex. The work of Josef Kumpán has mostly been documented by fully preserved planting plans. The present case study on a uniquely discovered specific planting plan of the landscape architect Josef Vaněk provides insight into how bush groups were handled, composed, and what was their specific composition. These documents allow comparing the creative approaches of landscape designers of this era. The study contributes to the reconstruction or maintenance of monument objects created in the interwar period.
