Published: March 2020

Introduction: It is important to educate young university students for adapting to social, economic and environmental changes in the world. It is not to prepare them just to be employees, but entrepreneurs who could be leaders in their fields, creating jobs and improving people’s quality of life. For this, there are entrepreneurship programs based on high impact project incubation, but there is still the risk of dropping out. For this, the objective of this study was to identify the factors which positively and negatively affect the entrepreneurship experience in university students, from the perception of young students who have already had an incubated project. Method: The study approach was qualitative, with an exploratory and descriptive type and a non-experimental and transverse design. The participants were twenty students who have already had an incubated project, registered at the Tax Agency and legally constituted as an enterprise, besides of their involvement in entrepreneurship activities along their education process at the institution. All of them were from a private university situated near Mérida city, Yucatán, in the Southeast of México, acknowledged for its entrepreneurship education as well as for its incubation and acceleration processes. A semi-structured interview guide was used, conducted by the researchers. Results: The factors that positively affect students to become entrepreneurs are personal ones, such as intrinsic motivation and the opportunity to be creative and dedicate to an interesting activity, accepting the risks. This is reinforced by the help of the coach, attendance to events, lectures and workshops, as well as constant feedback from expert panels. The ones which negatively affect the entrepreneurial experience are mainly external, such as the lack of monetary funds for living while the project is incubated, because when there are monetary resources, they are just for the project. There are also other internal factors such as the fear for making mistakes and the lack of experience for starting a business. Conclusions: The factors which prevent the entrepreneurship development depend on each participant more than in the method. The student must have time for the project and to continue his courses without the need to search for a job for making a living along the incubation. Then, there must be strategies to guarantee time and monetary resources so students don’t have distractors which could become entrepreneurship barriers. Besides, university study plans must be improved for enhancing creativity, innovation and entrepreneurship from initial stages. Incubators must be places for enhancing insertion of new enterprises in nets and create university clusters.

Published: March 2020

Este artigo é resultado de observação de campo em turmas de EJA. Nossas questões investigativas são: Quais as mediações pedagógicas possíveis para o efetivo ensino na Educação de Jovens e Adultos - EJA? Estão livres de impasses e contradições? O objetivo geral foi abordar os impasses e as contradições existentes no contexto das escolas da Educação de Jovens e Adultos (EJA), que no âmbito de nossa realidade está a perder espaço significativo de inserção social e de posse do conhecimento para aqueles que em tempo "regular" de suas vidas, não puderam dar seguimento em seus estudos. A atividade de observação de campo foi realizada numa escola estadual de Cruz Alta/RS., onde se verificou práticas didático-pedagógicas realizadas numa turma de Ensino Médio – T9, em aula de Matemática e em aula de História, com distintas mediações pedagógicas. Teórico-metodologicamente laborou-se com estudo de caso, buscando, responder adequadamente às nossas questões investigativas e com autores que investigam a questão EJA no Brasil, os quais estão citados no texto. Como resultado pôde-se, constatar duas situações distintas de mediação pedagógica: uma prática de ensino-aprendizagem alicerçada na didática tradicional (bancária), e outra prática alicerçada no contexto de vida dos alunos. Como resultado do trabalho investigativo: constatamos ser acanhado o número de professores preparados para ministrar aula em turmas de EJA, dada sua especificidade, sendo o processo de mediação pedagógica embasado em decisão pessoal do professor, bem como apuramos rara capacitação dos professores para o exercício de seu trabalho com alunos da EJA, gerando impasses e contradições.

Authors: Hagag Adel A. , El Frargy Mohamed S. , Yonis Reham L. , Al-Ashmawy Ghada M. 
Published: March 2020

Background:
Neonatal sepsis is a clinical syndrome characterized by symptoms and
signs of infection in the first twenty-eight days of life. Serum thyroid, cortisol and hepcidin are affected
by neonatal sepsis.

Aim of the work:
The aim of this study was to assess the diagnostic value of serum thyroid hormones
including free triiodothyronine (free TT3) and free tetraiodothyronine (free TT4), serum cortisol
and hepcidin levels through comparison of their concentrations between normal neonates and
neonates with high probable late-onset sepsis.

Patients and Methods:
This case-control study was carried out on 40 neonates with suspected high
probable late-onset neonatal sepsis based on clinical and laboratory finding who were admitted to
NICU of Pediatric Department, Tanta University, Egypt in the period from April 2017 to May
2019 (group I) and 40 healthy neonates matched in age and sex as a control group (group II). For
patients and controls, blood culture, highly sensitive C-reactive protein (H-s CRP), serum hepcidin,
serum cortisol and thyroid hormones levels including free TT3 and free TT4 were assessed.

Results:
There were no significant differences between studied groups regarding weight, gestational
age, sex and mode of delivery. H-s CRP, serum cortisol and hepcidin were significantly higher
in group I than group II while serum-free TT3 and free TT4 were significantly lower in group I
compared with controls (group II). There was significantly lower H-s CRP, serum hepcidin and cortisol
and significantly higher serum-free TT3 and free TT4 in group I after antibiotic therapy compared
to the same group before treatment while there were no significant differences between
group I after antibiotic therapy and control group (group II) regarding the same parameters. There
was a significant positive correlation between H-s CRP and serum hepcidin and cortisol in group I
while there was a significant negative correlation between H-s CRP and free TT3 and free TT4.
ROC curve of specificity and sensitivity of H-s CRP, serum hepcidin, cortisol, free TT3 and free
TT4 in the prediction of neonatal sepsis shows that serum hepcidin had the highest sensitivity and
specificity with 95% and 90% respectively followed by serum cortisol, H-s CRP, free TT3 and lastly
free TT4.

Conclusion and recommendations:
Neonates with high probable sepsis had significantly higher
serum cortisol and hepcidin and significantly lower free TT3 and free TT4 compared with healthy
neonates. These findings may draw our attention about the use of these markers in the diagnosis of
neonatal sepsis which can help in early treatment and subsequently better prognosis.
Prostate Cancer Detection in Screening Using Magnetic Resonance Imaging and Artificial Intelligence
Authors: Nelson Chris R. , Ekberg Jessica , Fridell Kent 
Published: March 2020

Background:
Prostate cancer is a leading cause of death among men who do not participate in a screening programme. MRI forms a possible alternative for prostate analysis of a higher level of sensitivity than the PSA test or biopsy. Magnetic resonance is a non-invasive method and magnetic resonance tomography produces a large amount of data. If a screening programme were implemented, a dramatic increase in radiologist workload and patient waiting time will follow. Computer Aided-Diagnose (CAD) could assist radiologists to decrease reading times and cost, and increase diagnostic effectiveness. CAD mimics radiologist and imaging guidelines to detect prostate cancer.

Aim:
The purpose of this study was to analyse and describe current research in MRI prostate examination with the aid of CAD. The aim was to determine if CAD systems form a reliable method for use in prostate screening.

Methods:
This study was conducted as a systematic literature review of current scientific articles. Selection of articles was carried out using the “Preferred Reporting Items for Systematic Reviews and for Meta-Analysis” (PRISMA). Summaries were created from reviewed articles and were then categorised into relevant data for results.

Results:
CAD has shown that its capability concerning sensitivity or specificity is higher than a radiologist. A CAD system can reach a peak sensitivity of 100% and two CAD systems showed a specificity of 100%. CAD systems are highly specialised and chiefly focus on the peripheral zone, which could mean missing cancer in the transition zone. CAD systems can segment the prostate with the same effectiveness as a radiologist.

Conclusion:
When CAD analysed clinically-significant tumours with a Gleason score greater than 6, CAD outperformed radiologists. However, their focus on the peripheral zone would require the use of more than one CAD system to analyse the entire prostate.

Published: March 2020

Background:
Lithium-rich layered materials with high discharge capacity are regarded as
one of the most promising cathodes for lithium-ion batteries (LIBs). However, they have been suffering
from rapid voltage fading and poor rate performance, which impede their practical application.

Methods:
Herein, Li1.2Mn0.6Ni0.2O2 with layered structure was successfully prepared by the ultrasonic
dispersion-assisted chemical reduction. X-ray powder diffraction (XRD), X-ray photoelectron
spectroscopy (XPS), scanning electron microscope (SEM), transmission electron microscope (TEM)
and electrochemical measurements were used to characterize its microstructure and electrochemical
properties.

Results:
The secondary particles of an as-prepared micro/nanostructured sample consist of irregular
and sheet-like rectangular blocks. Electrochemical results show that the initial charge and discharge
capacity within 2.0~4.8 V is 337.5 mA h g-1 and 236.9 mA h g-1 at 0.2C (1C = 200 mA g-1). The subsequent
discharge capacity is stabilized at about 210 mA h g-1 for more than 100 cycles. When the
current density is increased to 2C, the cycling columbic efficiency is maintained at 99.3% after 100
cycles.

Conclusion:
Thus, the Li1.2Mn0.6Ni0.2O2 cathode material prepared by ultrasonic dispersion-assisted
chemical reduction has a promising application in LIBs with high energy density and long cycle life.

Authors: Lei Ting-Ting , Han Hong-Mei , Liu Xiao-Jing 
Published: March 2020

Abstract

Objective
This study aimed to identify the mediation effects of health locus of control (HLC) and hope between stroke patients’ social support and self-management.

Methods
A cross-sectional study was conducted. A total of 300 Chinese stroke patients were recruited by convenient sampling from the acupuncture department of two Chinese Traditional Medical Hospitals in Tianjin Province from June to September 2018. The self-report questionnaires include Social Support Assessment Scale, Herth Hope Index, Mental Health Locus of Control Scale, Stroke Self-management Behavior Scale, and personal information questionnaires. All the survey data were entered in Excel and analyzed using the SPSS 24.0 program. Mediation was tested with Bootstrapping in AMOS 23.0 program.

Results
The result showed that internal health locus of control (IHLC), chance health locus of control (CHLC) and hope were the mediators between social support and self-management. The direct, indirect, and total effects of social support on self-management behavior were 0.306 P < 0.01), 0.109 (P < 0.01), and 0.415 (P < 0.01), respectively.

Conclusions
Social support can directly influence self-management, and it can also indirectly influence self-management through IHLC, CHLC, and hope.
Library and Information Science Vis-À-Vis Web Science in the Light of the OECD Fields of Science and Technology Classification
Authors: Grabowska Marta 
Published: March 2020

Abstract

Aims: The paper focuses on the methodological frames of Library and Information Sciences vis-à-vis Web Science in the light of the OECD Fields of Science and Technology Classification. The roots of Library Science and Information Science in Humanities and Social Sciences are described. The technological revolution which took place during and after World War II enabled the development of a new mathematics- and engineering-oriented environment for information. On this basis such new research areas like Web Science emerged. It led to a change towards an interdisciplinary character of Information Science. Method: The OECD Fields of Science and Technology Classification was analysed from the point of view of the Library and Information Science’s place in this classification.

Solutions: In the OECD Fields of Science and Technology Classification Library Science has its independent place within Social Sciences while Information Science is dispersed between three main sections. It confirms the interdisciplinary character of Information Science and sets up its name as a superior covering traditional Information Science and all of new mathematics- and engineering- based research areas dealing with information. Although the name Web Science is not mentioned in this classification, we can assume that it is a sub-discipline of Information Science in the light of the OECD classification. Polish implications are mentioned.
The Europeana Collections – Transylvanian Prints from the Collections of the National Museum of the Union from Alba Iulia
Authors: Negoi Ana Maria Roman 
Published: March 2020

Abstract
The Europeana Collections, inaugurated in 2008, represents the completion of an ambitious project intended to be a journey and an instrument for the access to the culture, the history and the identity of the Europeans. Nowadays, Europeana contains in its collections more than 58 million digital units, organized on domains and themes, from art works, artefacts and books to movies and music. The patrimony of the Europeana enriches yearly and constantly by the contribution of the European Member States, as response to the common aspiration to open the access to knowledge beyond the national or territorial borders. The Europeana Project represents the implementation by digitization of a set of standards and of a unitary approach on the valorisation by digitization of the patrimony of the European states. The country reports reflect the most accurate the measures and the achievements of each contributing state to Europeana. Therefore, the Romanian report – a document updated in January 2019 – presents punctually the achievements of our country and of the Romanian institutions contributing to the enrichment of the Europeana collections. The list of the contributors contains, next to the names of well-known libraries, the name of the National Museum of the Union from Alba Iulia, with 986 digital units. Related to the field of the prints, the National Museum of the Union is not a direct contributor, but its collections are uploaded by other contributors. The National Museum of the Union has a remarkable and extremely valuable collection of Transylvanian books, mainly printed in Cluj during the 18th century. There are 78 titles with a preponderantly religious, juridical and educational content, representing an important segment of the national cultural heritage. The present paper aims to approach the above mentioned works and to identify them in the Europeana collections.
Optical characterization of thin Al2O3 layers deposited by magnetron sputtering technique at industrial conditions for applications in glazing
Authors: Dywel Piotr , Skowroński Łukasz 
Published: March 2020

Abstract
In this study, thin Al2O3 films (11 nm – 82 nm) were deposited by means of a recently developed pulse gas injection magnetron sputtering method and investigated by means of atomic force microscopy, spectroscopic ellipsometry and spectrophotometry. Quite low values of optical constants (1.581 to 1.648 at λ = 550 nm) of the alumina films are directly associated with specific growth conditions (pulse injection of the reactive or reactive + inert gas) in the pulse gas injection magnetron sputtering process. The light transmittance of Al2O3/glass systems (86 % to 90 %) is only a few percent lower than that calculated for glass (93 %).

Authors: Chen Ming-Jui , Loan Nguyen Thi Phuong , Van Tho Le , Bui Thuc Minh , Le Phan Xuan , Anh Nguyen Doan Quoc , Liao Hsing-Yuan , Chang Jui-Chen , Lee Hsiao-Yi 
Published: March 2020

Abstract
As implied in the title, the triple-layer remote phosphor (TRP), constructed with the yellow YAG:Ce3+ layer at the bottom, the red CaMgSi2O6:Eu2+,Mn2+ phosphor layer on the top, and the green Ba2Li2Si2O7:Sn2+,Mn2+ phosphor layer between these two layers, is suggested in this paper to improve the color and luminescence of white LEDs (WLEDs). In order to control the red light for the purpose of increasing the color rendering index (CRI), it is suggested that the red CaMgSi2O6:Eu2+,Mn2+ phosphor should be applied in the TRP structure. Simultaneously, the structure uses the green Ba2Li2Si2O7:Sn2+,Mn2+ phosphor layer to control the green light, which increases the luminous efficacy (LE) of WLEDs. In addition, when the concentration of these two phosphors increases, the yellow YAG:Ce3+ concentration must be reduced to keep the average correlated color temperatures (ACCTs) stable at 6000 K to 8500 K. Besides, appropriate adjusting of CRI, LE, and color quality scale (CQS) is also analyzed by modifying the concentration of the green phosphor and red phosphor. The results show that the CRI can get better values if CaMgSi2O6:Eu2+,Mn2+ concentration is higher. In contrast, the CRI decreases dramatically when the concentration of Ba2Li2Si2O7:Sn2+,Mn2+ increases. Meanwhile, CQS can be significantly increased in the range of 10 % to 14 % CaMgSi2O6:Eu2+,Mn2+, regardless of the concentration of Ba2Li2Si2O7:Sn2+,Mn2+. In particular, along with the improvement of CRI and CQS, LE can also be increased by more than 40 % by reducing the scattered light and adding the green light. Obtained results are a valuable reference for manufacturers for improving WLEDs color and luminescence quality to produce a broader range of WLEDs with better quality fulfilling social needs.
Mechanical recanalization for acute bilateral cerebral artery occlusion – literature overview with a case
Authors: Jeromel Miran , Milosevic Zoran V , Oblak Janja Pretnar 
Published: March 2020

Abstract

Background
Acute bilateral internal carotid artery (ICA) and/or middle cerebral artery (MCA) occlusion is extremely rare and associated with poor clinical outcomes. There are only a few reports in the literature about mechanical thrombectomy being performed for acute bilateral occlusions. The treatment strategies and prognoses (clinical outcomes) are therefore unclear.

Methods
A systematic review of the literature was performed through several electronic databases with the following search terms: acute bilateral stroke, mechanical recanalization and thrombectomy.

Results
In the literature, we identified five reports of six patients with bilateral ICA and/or MCA occlusion treated with mechanical recanalization. Additionally, we report our experience with a subsequent contralateral large brain artery occlusion during intravenous thrombolytic therapy, where the outcome after mechanical thrombectomy was not dependent on the time from stroke onset but rather on the capacity of collateral circulation exclusively.

Conclusions
Acute bilateral cerebral (ICA and/or MCA) occlusion leads to sudden severe neurological deficits (comas) with unpredicted prognoses, even when mechanical recanalization is available. As the collateral capacity seems to be more important than the absolute time to flow restoration in determining the outcomes, simultaneous thrombectomy by itself probably does not lead to improved functional outcomes.
The Cognitive Motivation Behind the Semantics of Hungarian Co-Verbial Constructions with Össze and Szét
Authors: Grygiel Marcin 
Published: March 2020

Abstract
The use of an elaborate system of co-verbial constructions is the hallmark of the Hungarian language and one of the biggest challenges a translator or a learner of this language has to face. Co-verbial constructions consist of verbs, or their derivates, accompanied by a limited number of prefixes or particles that modify their meanings. They not only perform numerous syntactic and lexical functions, which is important in terms of language production, but also are able to change the meaning of the verb completely. The aim of this study is to trace the cognitive motivation behind the use of Hungarian co-verbial constructions with össze/szét and to show that the meanings developed by these constructions can be organized with reference to prototypical scenes structured in the form of a radial category.
“That’s the Metaphor You’re Going for?” Deliberate Metaphor and Humor
Authors: Wawrzyniuk Justyna 
Published: March 2020

Abstract
This paper aims at discussing the function of deliberate metaphors in humorous narratives due to the similarities in mechanisms underlying both elements of language. This corpus-based analysis has shown the relation between deliberate metaphors and elements of the knowledge resources of the General Theory of Verbal Humor (GTVH). The study has revealed that if deliberate metaphors are part of humorous narratives, they are more likely to be the source of the funniness rather than the transit system which conveys the metaphors themselves. With this in mind, it is possible to assess the extent to which deliberate metaphors contribute to humor.
