Sensitivity of Aerodynamic Characteristics of Paraglider Wing to Properties of Covering Material
Authors: Maślanka Paulina , Korycki Ryszard 
Published: May 2020

Abstract
The paper is theoretically oriented. The main goal is to analyze the sensitivity of aerodynamic characteristics to the properties of the material used for paraglider wing. The paraglider of considerable dimensions is designed without stiffening elements. Thus, the covering material yields adequate pressure distribution between the external and internal parts of the wing. The problem is solved using a geometrical model approximated by the dimensionless coordinates of crucial points and smoothed by spline curves. The finite volume mesh is defined using the Ansys Meshing program. Numerical analysis uses five different covering materials, ranging from the air-impermeable covering to the covering subjected to hydrolytic—mechanical degradation. Optimization of properties of the covering material improves the lift force and the aerodynamic characteristics of the wing. Moreover, numerical modeling is more beneficial and efficient than prototype tests. The obtained pressure distributions and other parameters explain the aerodynamic safety of the paraglider during dynamic conditions of flight.
The Influence of Brand on Consumer Quality Assessment of Clothes: A Case Study of the Polish Market
Authors: Salerno-Kochan Renata , Turek Paweł 
Published: May 2020

Abstract
This article presents the results of research carried out based on consumer assessment of the quality of clothing using sensory analysis. The study aimed to determine the role of the brand and information about it in assessing product quality and identify the quality parameters that distinguish brands of a similar quality level. An attempt was also made to classify popular brands of clothing available on the Polish market based on the parameters that determine their quality. A significant impact of the brand name on the sensory assessment of clothes’ quality has been reported. The study has shown that assessors attribute higher rating values to quality features when they know the product brand; moreover, the brand and its information shortens the assessment time, which may suggest that it simplifies and facilitates consumers’ decision-making process. The result analysis has led to the identification of three groups of the factors determining the quality of clothing products: fabric composition, workmanship, and all other variables. It has also led to the separation of three clusters, characterized by different levels of product quality, for which sets of features distinguishing a given category were determined.

Summary

Study aim: To evaluate the effect of power and muscle strength training on skin temperature and the performance of the vertical jump with countermovement (CMJ).

Material and methods: The sample consisted of four male basketball athletes of the under-17 category (age: 15.75 ± 1.0 years). 48 hours after anthropometric evaluation and determination of the loads for 1 repetition maximum (1RM) in the leg extension exercise, the athletes were subjected, through crossover-type entrance, to power (PTP) and strength (STP) training protocols. The protocols consisted of three sets with loads of 60% and 90% of 1RM for PTP and STP, respectively. Thermographic images of the thighs were taken before and immediately after each training session.

Results: There were significant differences in results between the two training protocols, with increased total repetitions (t = 13.481; p < 0.05) and total training volume (t = 15.944; p < 0.05) in the PTP, and increase in the % of 1RM (t = 33.903; p < 0.05) and rating of perceived exertion (t = 6.755; p < 0.05) in the STP. The skin temperature before and after PTP and STP showed no significant differences. In the post-STP, the CMJ presented significant reductions in height (t = 3.318; p < 0.05), flight time (t = 3.620; p < 0.05), velocity (t = 3.502; p < 0.05), and force (t = 4.381; p < 0.05). There were no significant differences in pre-and post-STP CMJ.

Conclusions: Power and maximum strength training in the leg extension exercise performed until concentric failure appears to be a method that induces thermal stress on the skin. This training directly influenced the performance of the vertical jump after the stimulus.

Authors: Buśko Krzysztof , Kopczyńska Justyna , Szulc Adam 
Published: May 2020

Summary

Study aim: The aim of the study was to examine the differences in physical fitness between deaf female soccer players and their deaf peers who did not practise any sport.

Material and methods: The research involved 13 deaf female soccer players and 16 deaf untrained girls. Physical fitness was assessed by a jump test and the Eurofit test. In the jump test, each participant performed an akimbo counter-movement jump (ACMJ), a counter-movement jump (CMJ) and a spike jump (SPJ) on a force plate. The following trials of the Eurofit test were performed: flexibility – sit-and-reach; static strength – hand grip; functional strength – bent arm hang (arm and shoulder muscular endurance); explosive strength – standing broad jump; and trunk strength – sit-ups (abdominal muscular endurance).

Results: Soccer players jumped significantly higher than untrained females in the ACMJ, CMJ, and SPJ, and developed significantly higher power of the CMJ. Relative power developed in the ACMJ and SPJ did not differ between the examined groups. Soccer players were physically fitter than girls who did not play any sport. Significant differences between the groups were observed for all measured trials except for the bent arm hang.

Conclusions: Hearing loss does not significantly determine the physical development or physical fitness of deaf people. Playing sports improves the physical fitness of deaf people in comparison with untrained deaf people.

Published: May 2020

Summary

Study aim: The aim of the study was to evaluate the effectiveness of Shantala massage during the classes conducted using the Developmental Movement method in improving the “with” relationship in healthy children aged 3 to 4 years.

Material and methods: The study involved 12 healthy children aged 3 to 4 years participating in SDM classes with their parents. The participants were divided into two groups. In the experimental group, Shantala massage was used during play based on the “with” relationship, whereas the massage proposed by Veronica Sherborne was performed in the control group. The Child Behaviour Observation Scale (SOZ-D) was employed to assess the improvements of psychomotor development. The study was a two-stage study, before the Sherborne Developmental Movement Method programme (initial observation) and after six months of classes (post-observation). The duration of the programme was 6 months. Classes were conducted once a week for 40 minutes.

Results: It was found based on the analysis of the results that the introduction of Shantala massage led to a significant increase in the assessment of child development on the subscale of emotional development.

Conclusions: The use of Shantala massage during SDM classes has a positive effect on emotional development of healthy children aged 3 to 4 years.
Joseph A. Greenaway Jr. Lecture Series on Law and Justice* Speak at Your Own Peril
Authors: Greenaway Joseph A. 
Published: May 2020

Abstract
This lecture given at Birmingham City University School of Law, March 21, 2019 considers the origins of the right to silence in the jurisprudence of the Supreme Court of the United States and compares the constitutional protections against self-incrimination with those of the United Kingdom. It notes that the effect of the changes introduced by the Police and Criminal Evidence Act 1984 and the Criminal Justice and Public Order Act of 1994 is that there is now a fundamental divergence in approach between the two jurisdictions and concludes that as the twenty first century progresses, defendants on both sides of the Atlantic will be less likely to exercise their rights without consequence and then when they do choose to speak it will be at their peril.
IDD – A Platform Enabling Differential Debugging
Authors: Vassilev Martin , Vassilev Vassil , Penev Alexander 
Published: May 2020

Abstract
Debugging is a very time consuming task which is not well supported by existing tools. The existing methods do not provide tools enabling optimal developers’ productivity when debugging regressions in complex systems. In this paper we describe a possible solution aiding differential debugging. The differential debugging technique performs analysis of the regressed system and identifying the cause of the unexpected behavior by comparing to a previous version of the same system. The prototype, idd, inspects two versions of the executable – a baseline and a regressed version. The interactive debugging session runs side by side both executables and allows to examine and to compare various internal states. The architecture can work with multiple information sources comparing data from different tools. We also show how idd can detect performance regressions using information from third-party performance facilities. We illustrate how in practice we can quickly discover regressions in large systems such as the clang compiler.

Published: May 2020

Abstract
Hoax news in Indonesia spread at an alarming rate. To reduce this, hoax news detection system needs to be created and put into practice. Such a system may use readers’ feedback and Naïve Bayes algorithm, which is used to verify news. Overtime, by using readers’ feedback, database corpus will continue to grow and could improve system performance. The current research aims to reach this. System performance evaluation is carried out under two conditions ‒ with and without sources (URL). The system is able to detect hoax news very well under both conditions. The highest precision, recall and f-measure values when including URL are 0.91, 1, and 0.95 respectively. Meanwhile, the highest value of precision, recall and f-measure without URL are 0.88, 1 and 0.94, respectively.
Robust Gain-Scheduled PID Control: A Parameter Dependent BMI Solution
Authors: Shao Pengyuan , Wu Jin , Ma Songhui 
Published: May 2020

Abstract
In control practices, problems of parametric or time-varying uncertainties must be dealt with. Robust control based on norm theory and convex and non-convex optimization algorithms is a powerful tool to solve these problems in theory, but it is employed rarely in applications. In most engineering cases, Proportional-Integration-Derivative (PID) control is still the most popular method for its easy-to-tune and controllable properties. The control method proposed in this paper integrates the PID control into robust control formulation as a robust Structured Static Output Feedback (SSOF) problem of Linear-Parameter-Varying (LPV) systems, which can be converted into a Parameter Dependent Bilinear-Matrix-Inequality (PDBMI) optimization problem. A convex-concave decomposition based method is given to solve the proposed PDBMI problem. The proposed solution has a simple structure in PID form and can guarantee stability and robustness of the system being controlled in the whole operation range with less conservativeness than existing solution.
Corporate volunteering in the large enterprises’ social mission – the case of a post-Soviet Russian industrial region
Authors: Pevnaya Maria , Cernicova-Buca Mariana 
Published: May 2020

Abstract
The paper focuses on the main features of corporate volunteering in companies from the Sverdlovsk region (Russian Federation), with a population surpassing 4.5 million inhabitants. Corporate volunteering is analyzed in the context of the trend characteristic for the post-Soviet space. The article systematizes approaches to the definition and study of this phenomenon, implemented by researchers from different countries. The main goal of the article is to identify the specific features of corporate volunteering in a large Russian region, considered typical for industrial territories in post-Soviet areas, seen through the social value that local communities attribute to corporate volunteering. The paper is based on the results of a public opinion poll and structured interviews, carried out in the Sverdlovsk region, where there is a concentration of enterprises of “hard” industries. The responses obtained in the poll were further subjected to analysis using statistical methods. The data are supplemented with information collected through the qualitative interviews. Interviewed experts are the top managers of enterprises and the deputy directors for HR, GR, or social issues. The study shows that in Russian industrial cities, where large enterprises are the main employers for most residents, many questions on the implementation of social policy fall under the responsibility of these enterprises, and not of the local government. Researchers argue that corporate volunteering is not widespread in the large Russian regions. It most often develops within the framework of event planning and environmental projects, managed by enterprises in cooperation with social and cultural institutions of local communities and not with the non-profit sector. The traditions of the organization of mass social work formed during the socialist period are still deeply rooted in enterprises, and managers rarely identify volunteering as a new managerial tool, thus being untangled from the global trend of promoting corporate volunteerism as a means of building corporate culture.
Influence of angiotensin-converting enzyme inhibitor ramipril on indicators of tubular kidney lesion in patients with chronic glomerulonephritis
Authors: Dolinna Mariia O. , Svyntozelskyi Oleksandr O. 
Published: May 2020

Abstract
To research and deepen the understanding of the links between morphological tubular kidney lesion parameters and serum markers – neutrophil gelatinase-associated lipocalin (NGAL) and interleukin-18 (IL-18), in patients with chronic glomerulonephritis (CGN) with saved renal function, as well as to estimate therapeutic correction of identified changes using ACE inhibitor ramipril. The diagnosis of “chronic glomerulonephritis” was verified based on clinical, laboratory and morphological data. Patients were divided into 2 clinical groups: patients with CGN and arterial hypertension (AH) and without AH. We used the data of renal biopsies to analyze the indicators of tubular kidney lesion in patients with CGN. Levels of serum NGAL and IL-18 were measured by means of ELISA kits. Treatment of patients was carried out over 24 weeks using the ACE inhibitor ramipril. The average daily dose of ramipril for the entire treatment period for patients with AH was 12.8±5.6 mg, patients of the second group – without AH, were treated with ramipril at a dose of 2.5 mg. On the basis of rank correlation analysis, we demonstrated that the level of serum NGAL is directly correlated with interstitial fibrosis (r=0.65; p<0.05), serum IL-18 – with dystrophic changes in the epithelium of renal tubules (r=0.81; p<0.05).

Conclusion. Serum levels of NGAL and IL-18 are one of the most sensitive markers of tubular kidney lesion and have diagnostic efficiency up to 97%. A 24-week treatment with ACE inhibitor ramipril in patients with CGN with and without AH leads to a decrease in the levels of tubular kidney lesion markers.
The Relevance of the Master’s in Engineering Education at a University of Technology in South Africa
Authors: Moloi Kholeka , Ndege Maurice 
Published: May 2020

Abstract
The purpose of this theoretical paper is to explain the relevance of the Master of Engineering Education (M Eng. in Education) at one university of technology in South Africa, that comprises four distinct faculties. The paper is based on relevant literature review. The M Eng in Education creates the nexus between Engineering Sciences and Education as specific fields of study and research to enhance cross-boundary knowledge, skills, pedagogy and application. This is in line with the South African National Development Plan, Vision 2030, that accentuates the need for Science, Technology, Engineering and Mathematics (STEM) education in the country to address the economy, develop skills, create jobs, eradicate poverty and unemployment towards a capable developmental state. Using a social constructivist lens, the researchers draw from their experiences while working with Engineering lecturers who enrolled for the Postgraduate Diploma in Higher Education (PGDHE) programme, offered within the institution. From the interaction with the Engineers through the PGDHE programme, the researchers found that the teaching and research skills of these engineers fundamentally improved because they had to submit long essay-type assessments. The researchers conclude that the M Eng in Education will enable engineers to teach better and improve student learning within their classrooms.

Authors: Cooke Lesley Anne , Lungu Bwalya , Samuels Lavern 
Published: May 2020

Abstract
Internationalisation and decolonisation are both prominent issues currently being discussed in South African Higher Education institutions. There is a strong impetus for decolonisation of curriculum design, development and delivery. Experience with the implementation of Collaborative Online International Learning at Durban University of Technology (DUT) has demonstrated that this approach to has immense potential for transformation of learning and teaching. The broader concepts of e-internationalisation and Virtual Engagement allow for even greater flexibility in fostering international collaboration, and opportunities for decolonisation of the curriculum. This paper briefly discusses internationalisation and decolonisation in general and at DUT specifically, and explores the opportunities that VE offers to address these imperatives in the implementation of the Personalised Engineering Education (PEESA) III Project.

Authors: Duşe Dan-Maniu , Simó Ildikó 
Published: May 2020

Abstract
To change the educational scene in the epoch of the digital generation there is the possibility of using Open Education (OE) and Open Educational Resources (OER). The term “open educational resources” refers to resources with free access to use, adaptation and redistribution. The objectives of the research are to determine the degree of knowledge and use of OER in three Engineering Universities in three countries (Poland, Hungary and Romania) and to find out whether there is a relationship between the institutions in terms of knowledge and use of OER. The measurement is made by applying the survey method on a sample of n = 192. As a tool we use the questionnaire with 15 questions structured in three chapters: knowledge of OER; using OER; opinions about OER. In this analysis we summarize: the presentation of the degree of familiarity with some OER-related concepts, the use of special search engines, the use of free software sources, the frequency of use of OER and opinions on different types of OER that could be exploited in the future. For the description of relationship between nominal variable we use contingency tables and diagrams and compare the frequency data with the Pearson Chi-square test.
Preannouncement of New Products: Overcoming Individual Adoption Barriers
Authors: Pezoldt Kerstin , Correns Anne , Zajko Marian 
Published: May 2020

Abstract
The launch of innovative products very often encounters adoption barriers of consumers. A suitable communication with consumers is the new product preannouncement (NPP). It helps reduce adoption barriers and accelerates the adoption process. It is an important communication instrument for innovative SMEs. After defining NPP, the paper analyses the content structure of the main components contained in NPP from a consumer point of view. Based on the analysis of existing literature the authors found that there were only a few studies on the properties and quality of information communicated in NPP that influence a successful market launch of product innovations. Above all there is a lack of studies on NPP content in terms of a successful market launch of product innovations. The following analysis of the main NPP components enables to derive recommendations for SMEs on the communication policy for preannouncements and launching product innovations in order to reduce individual adoption barriers.

Abstract
Due to our previous experience in AR development, with this research project we propose to study how Augmented Reality (AR) can be adopted by an industrial partner and which are the major outcomes from which a company may benefit. For this purpose, we partnered with a forward-looking company willing to embrace the idea of implementing new technologies for industrial purposes. In this research we identified that the most significant impact which AR may have for our industrial partner is in providing remote assistance and for product exploitation and marketing purposes. For the latest we developed a customized AR application which is currently available on Apple’s App Store. By analysing the app analytics data, we found out that this application is a success in terms of marketing and not only. For the remote assistance AR app, we chose to use a commercial solution that can be adapted to fit our industrial partner’s needs. We also tested this application and found out that it greatly improves the communication between remote users thus dismissing the required assistance time.
