Authors: Bordachev Dmitry V.
Published: April 2021

Problem and goal. The development of mass open online courses contributes to the increasing attention of students to them. At the moment, there are many large services that provide online training, but there are no clearly defined universal requirements for such courses. Also, along with this problem, there is a fairly high level of rejection of the course at various stages due to the loss of motivation to continue training. Methodology. A variant of solving these problems by using adaptive learning technologies on the example of a course on learning artificial neural network technologies was considered. Results. In the process of reviewing the issue, the topics of the online course sections were determined. As a result, a work plan was drafted and the most relevant ways to solve the identified problems were formulated. Conclusion. The developed strategy can help with further elaboration and testing of the designed course and can be applied to any mass open online course.

Published: April 2021

Problem and goal. In Russian society, the simultaneous and mass transition to distance learning of educational organizations in March 2020 in connection with a new coronavirus infection caused a sharp discussion about the effectiveness and consequences of this format of training, as well as about the prospects for its use after the COVID-19 pandemic. In the current conditions, the education system is faced with the task of training specialists in the face of the uncertainty of the future and the accelerated digitalization of the economy. The purpose of the research is to analyze the main factors influencing the development and spread of distance learning in the coming years, as well as the possible short and long-term consequences of switching to distance learning in higher education institutions. Methodology. The analysis of the scientific literature and practical activities, as well as experienced teaching, was used in the study. Results. The content and form of education will significantly transform in the long term. Today the necessary digital competencies cannot be acquired within the framework of the traditional educational process (lectures, seminars, exams in oral form), without the systematic use of information technologies in the educational process. Information technologies will be in high demand by graduates and will allow them to be prepared for the practical use of IT in the workplace. In addition, it can significantly improve the effectiveness of training because it allows to implement an individual learning trajectory, personalize training, remove restrictions on the time and place of training, and increase the visibility and interactivity of the educational process. Conclusion. Online education, e-learning using distance learning technologies in the long term will meet the demand of students and society for training in an uncertain future. Thanks to information technologies, conditions are created for active cognitive and educational activities of students, individualization of training is provided, turning the student into an active and equal participant in the educational process, including by refusing to provide ready-made differentiated knowledge, which leads to the formation of the reproductive nature of thinking in students.

Published: April 2021

Background: To determine the frequency of breastfeeding of mothers
working in primary care, the differences between different employment
groups, and the effective factors. Methods: This descriptive research
study was conducted with a self-report online survey design. The
snowball sampling method was used for the sample selection, and 151
family physicians and 126 family health professionals were included in
the study during the research period (June 2019-December 2019). A
35-item survey was used to collect data. The response rate was 44.9%
(49.5% family physicians/40.3% family health professionals). Results:
The mean duration of exclusive breastfeeding was 3.9 ± 2.0 months, and
the mean duration of total breastfeeding was 16.7 ± 8.5 months. There
was no significant difference between the family physicians and family
health professionals in terms of exclusive breastfeeding (P = 0.580) and
total breastfeeding (P = 0.325) durations. The most common reasons for
weaning was reduced milk supply (25.6%) and not being able to use
breastfeeding leave (23.1%) due to problems at work. Of the sample,
41.3% had problems with their co-workers and 41.9% had problems
related to patient care when taking breastfeeding leave. Working in a
baby-friendly center (P = 0.010), prolonged exclusive breastfeeding (P
< 0.001), and increased hours of breastfeeding leave taken (P
= 0.001) had a positive effect on breastfeeding for ≥24 months while
experiencing problems with co-workers in taking breastfeeding leave (P =
0.023) had a negative effect on this variable. Conclusions: All of the
factors that were determined to affect the continuation of breastfeeding
for ≥24 months are modifiable. It is very important for relevant
authorities to undertake necessary action to improve the conditions of
working mothers based on these results. Health professional that can
maintain the balance between family and work will work more efficiently.

Authors: Bahrami Mohammad , Malakouti Mohsen , Farrokhabadi Amin
Published: April 2021

In this research, the effects of induced delamination on the variation
of the mechanical properties of composite laminates subjected to bending
loads are investigated using a micromechanical model. For this purpose,
the variation of the mechanical properties of delaminated laminates is
determined using stress analysis of damaged ply and classical laminate
theory (CLT) relationships. Using the proposed model and CLT, the
fracture toughness due to induced delamination formation is presented in
cross-ply laminates. Subsequently, the variation of strain energy
release rate (SERR) is calculated in terms of crack density using
analytical and finite element models to detect dominant failure modes in
different crack densities. The results are compared with those of matrix
cracking propagation. The results obtained by the proposed analytical
model are in good agreement with those obtained by existing numerical
and experimental approaches. The proposed model can be utilized to
predict induced delamination formation in composite laminates subjected
to bending loads.

In this study, the objective was to evaluate the effect of the age of Hy-line Brown hens – 44 and 60 weeks of age (26 and 42 weeks of laying) and housing system (enriched cages and litter) on the quality of eggs. According to our results, eggs with a better quality of albumen were obtained from younger hens than from older hens. Moreover, older hens produced eggs with inferior quality related to shell parameters, such as greater elastic deformation, poorer breaking strength, and thinner shells. However, hens kept in a litter housing system laid eggs with superior shell quality characteristics of less flexible and greater breaking strength, even though the thickness, weight, and percentage were similar in both housing systems. In addition, a higher amount and activity of lysozyme were obtained from eggs laid by hens kept in the litter housing system than those obtained from hens kept in cages. The maintenance system and age of birds also had a significant (P≤0.05) effect on the basic chemical composition of eggs, as well as on the proportion of individual elements and fatty acid profile. Taking these results into account, we can conclude that the more valuable characteristics from the morphological and nutritional point of view were observed in eggs obtained from younger Hy-line hens kept in the litter housing system.

Published: April 2021

This study aimed to explore the potential impact of the Lean Manufacturing methodology on the implementation and functioning of the BRC Standard for Packaging. The study highlighted many issues where the Lean Manufacturing concept supports and opposes the BRC Standard for Packaging. A framework for the coexistence of both approaches was determined. The study was of a conceptual nature; it adopted an analytical approach. The approach was based on in-depth consideration of each requirement in the BRC Standard for Packaging s and an assessment of the coherence with the Lean Manufacturing methodology. As a result, many conclusions, clues and challenges were found. The article indicates several areas, in which Lean Manufacturing supports the BRC Standard for Packaging, attributing a special positive role to Lean Tools & Techniques. Also, it indicates six areas, in which the BRC Standard for Packaging contradicts the Lean Manufacturing approach. A comprehensive analysis of the coexistence of both management systems allows a better understanding of challenges while implementing both of them in an organisation. The presented concept of the coexistence of both systems is valuable for management.

Authors: Todorović Jadranka Đurović , Đorđević Marina , Krstić Marko
Published: April 2021

The importance of certain tax forms for the economy of any country is confirmed by the fact that they can be used to impact on the achievement of fiscal aims as they play a significant role when it comes to their share in a total amount of public revenue of certain countries. Another important characteristic of taxes is that they can affect the trends of gross domestic product (GDP) as one of the most important economic indicators of achieved development of a national economy. It is for this reason that we must point out that the authors will pay special attention to determining the impact that corporate income tax has on trends of gross domestic product in the Republic of Serbia and their interdependency. This will provide an answer to a question whether corporate income taxes have a positive effect on gross domestic product trends and what is its relation with this indicator. On the basis of quantitative research, through the application of regression analysis, the authors will confirm or refute the hypothesis concerning this problem. Finally, we will reach a conclusion which will offer answers to questions related to the impact of this tax type tax on the gross domestic product trends, the extent of the impact and its nature – whether it has a positive or a negative effect on gross domestic product trends in the Republic of Serbia
Effects of Plyometric vs. Combined Plyometric Training on Vertical Jump Biomechanics in Female Basketball Players
Authors: Sánchez-Sixto Alberto , Harrison Andrew , Floría Pablo
Published: April 2021

The purpose of this study was to assess and compare the effects of plyometric training and combined training programs on vertical jump kinematics and kinetics of female basketball players. Thirty-six female basketball players were included in the study and further divided into three groups: plyometric training, n = 11; combined training n =13; and a control group, n =12. Combined training comprised full squat exercise with low resistance (50-65% 1RM) and low volume (3-6 repetitions/set) combined with repeated jumps. Plyometric training included drop jumps and repeated jumps. Both training methods showed a moderate increase in jump performance, although combined training achieved substantially higher values than plyometric training alone. After plyometric training, the vertical velocity and displacement of the center of mass of the countermovement jump increased, while force variables decreased. Combined training increased power, vertical velocity and displacement of the center of mass, but force variables remained unchanged. Both training methods improved jump height, velocity and displacement of the center of mass. Combined training maintained force measures while plyometric training decreased them. These results indicate that combined training might provide better outcomes on jump performance than plyometric training alone. It also appears important to measure biomechanical variables to appropriately interpret the effects of different training methods.
Solitary Fibrous Tumor of the Pleura: Case Report and Literature Review
Authors: Stoian Marilena , Indrei Lucia , Stănică Roxana , Stoica Victor
Published: April 2021

Solitary fibrous tumours of the pleura (SFTPs) are rare neoplasms, usually described as relatively benign neoplasms and only 10-20% presenting malignant features. Imagistic investigations are useful in the incipient evaluation of SFTPs, and the histopathological and immunohistochemical examinations after surgical resection are mandatory for establishing the diagnosis and for differentiating SFTPs from other aetiologies of pleural masses. The unpredictable evolution (10%-20% of the cases reported in literature display malignant features) and limited data regarding the treatment needs an early detection, a complete surgical resection and long-term imagistic follow-up. We present a case of SFTPs alongside a review of the typical clinical, imagistic and pathologic features consistent with this diagnosis.
The Napkin-Ring Sign – the Story Behind Invasive Coronary Angiography
Authors: Parajkó Zsolt , Kovacs István , Chițu Monica , Benedek Imre
Published: April 2021

Coronary artery disease (CAD) represents one of the leading causes of morbidity and mortality across Europe. Most of the patients do not experience any warning sign before the coronary event develops, therefore screening this group of patients is essential to prevent major cardiac events. Coronary computed tomography angiography (CCTA) offers a noninvasive approach of the coronary arteries, providing information not only on the presence and severity of the coronary stenosis, but is also able to characterize the structure of the coronary wall. CCTA allows complex evaluation of the extension of CAD, and by assessing the structure of the atherosclerotic plaque, it can identify its degree of vulnerability. The napkin-ring sign (NRS) represents a ring-like attenuation of the non-calcified portion of the coronary lesion and has a high specificity (96–100%) for the identification of thin cap fibroatheroma (TCFA) or culprit lesion in acute coronary syndromes (ACS). It is also an independent predictor for ACS events and the strongest predictor for future ACS. Modern CCTA can provide submillimeter isotropic spatial resolution. Thus, CT attenuation-based tissue interpretation enables the assessment of total coronary plaque burden and individual plaque components, with a similar accuracy as intravascular ultrasoud-based investigations. This review aims to present the important role of CCTA as a potent screening tool for patients with CAD, and the current evidences in the detection and quantification of vulnerable plaques.

Published: April 2021

Multivessel coronary artery disease, defined by the presence of a significant stenosis (≥50% diameter) in two or more epicardial coronary vessels, usually occurs in more than 50% of patients with ST-segment elevation myocardial infarction. The latest guidelines indicate revascularization of the non-culprit artery with a recommendation of class IIB. However, the management of non-culprit lesions in patients with acute coronary syndrome is still a matter of debate. This article presents the most recent concepts related to the management of culprit and non-culprit coronary lesions, based on advanced imaging approaches, in order to identify high-risk patients and prevent further acute coronary syndromes.
The Cultural Context of Reception:
Authors: Korppi-Tommola Riikka
Published: April 2021

The reception of the Merce Cunningham Dance Company and John Cage’s visit to Helsinki in 1964 revealed local, Finnish aesthetic priorities. In the dance critics’ texts, Cunningham’s style seemed to create confusion, for example, with its mixture of styles visà-vis avant-garde music. Music critics, mainly avant-garde and jazz musicians, had high expectations for this theatrical event. In their reviews, comparisons were made between Cunningham’s style and the productions of Anna Halprin. In this paper, I analyse the cultural perspectives of this encounter and utilize the theoretical framework of Thomas Postlewait’s pattern of cultural contexts. Additionally, I follow David M. Levin’s argumentation about changes in aesthetics. Local and foreign conventions become emphasized in this kind of a transnational, intercultural encounter. Time and place are involved in the interpretations of the past as well as later in the processes of forming periods.
A Comparison of the Effects of Resistance and Endurance Training Protocols on Serum Irisin Level and Alkaline Phosphatase Activity in Sedentary Obese Women
Authors: Poutafkand Fereshte , Marefati Hamid , Taherichadorneshin Hossein
Published: April 2021

Introduction. Studies have revealed that the anabolic effect of irisin on bone is mediated by an increase in alkaline phosphatase. However, few studies have investigated the interactive effect of irisin on alkaline phosphatase after exercise training. Therefore, the present study aimed to compare the impact of endurance and resistance training protocols on serum irisin concentration and total alkaline phosphatase activity in sedentary obese women.

Material and methods. Forty-five sedentary obese women (age: 48.96 ± 5.2 years, body mass index 32.24 ± 3.76 kg/m2) were randomly assigned to control, endurance, and resistance groups. Endurance (45 to 75 minutes at an intensity corresponding to 50 to 80% of heart rate reserve) and resistance exercise training (3 sets, 10-15 repetitions at an intensity corresponding to 50 to 65% of one-repetition maximum) were conducted for 8 weeks, 3 days per week. Maximal oxygen consumption (VO2max) was estimated using the modified Bruce protocol treadmill test. Fasting blood samples were taken before the first and 48-hr after the last exercise training sessions. The serum concentrations of irisin and total alkaline phosphatase activity were measured using the sandwich ELISA method and photo-metric method, respectively.

Results. Both endurance and resistance exercise training protocols caused a significant reduction in BMI and BFP of obese women. In contrast, VO2max significantly increased after both exercise training protocols. However, neither endurance nor resistance training protocols had a significant impact on the serum concentrations of irisin and total alkaline phosphatase activity. No significant inter-group differences were observed between the subjects’ BMI, BFP, VO2max, total alkaline phosphatase, and irisin at the end of protocols.

Conclusions. The finding of the current study revealed that neither of the training protocols had a significant impact on bone anabolic parameters. However, performing these types of exercise is suggested for weight management in obese women.

“Not just somebody’s mother”: University Campus Daycare Co-operatives in Ontario and British Columbia, 1960s to 1970s
Authors: Simon Katherine Clare
Published: April 2021

Daycare is now a common sight on university campuses, but this was not always the case. Using the case studies of Simon Fraser University, the University of Toronto, and Queen’s University, this project examines the creation of daycare co-operatives on university campuses. The research makes clear that the formation of the co-operatives stemmed from the New Left and Women’s Liberation Movements. The radical ideology that the co-operatives took from these movements frequently caused friction and conflict with the liberal university and provincial administration. The co-operatives challenged and adapted to these pressures. They also challenged the nuclear family and the gendered division of care work. In the end, however, the projects were co-opted by university administration. Despite their inability to continue as co-operatives, these experiments in accessible and affordable daycare laid the groundwork for the recognition of the importance of childcare on university campuses and the responsibility of institutions to provide it.
Streamlining the Testing Process of Photonic Chips
Authors: Xie Anne
Published: April 2021

The Shastri lab focuses on generating advanced photonic chips for signal processing and computing by combining artificial intelligence (AI) and photonics. These chips are utilized in neuromorphic silicon photonics which has various applications such as improving computational efficiency in AI and neuromorphic computing hardware. One of our advanced chips can be divided into three physical components: receiving a light signal, modulating the signal, and lastly detecting the signal with a photodetector on chip. Prior to utilizing these chips for experiments, it is vital to ensure that all components are functioning correctly.

My work focused on streamlining the testing process of the photodetector by improving the signals used within the process. In order to test the photodetector, the light entering must be modulated externally using a Mach-Zehner Modulator (MZM). The MZM takes in a light signal and splits it into two where they experience a phase shift and when the two are recombined create a modulated signal. The signal’s modulation is determined by changing the radio frequency (RF) signal sent from a driver into the modulator.

Another aspect of my work was enhancing the control of the RF signal produced by the driver. The driver requires specific positive and negative voltages to generate ideal frequencies which are supplied by a unique power source. The voltage source was designed to ensure that the driver never received a damaging current or voltage and had a user-friendly interface to control the modulation of the signal.
Sisterhood and Solidarity: An Exploration of the Role of Women in the Development of Chinese-Indigenous Relations in Disappearing Moon Cafe and “Yin Chin”
Authors: Lalani Sarenna
Published: April 2021

History class tells us a narrative of first contact between Indigenous people and colonizers that is very narrow in scope. The discussion is often limited to accounts of European colonizers; the brutal assimilation tactics that destroyed the culture of the first peoples of this land are often excluded. Also forgotten are the other stories of first contact that existed synchronously – the stories that do not revolve around dominant society. Sky Lee’s Disappearing Moon Café provocatively spotlights the instances of connection between Chinese and Indigenous communities both historically and in modern day. Lee cautiously manoeuvres around issues of love, miscegenation, intergenerational trauma and cultural norms, particularly focusing on the relationships that exist between both Chinese and Indigenous characters and communities. Lee Maracle focalizes these Chinese-Indigenous relationships from an Indigenous perspective in her piece “Yin Chin.” Together, the texts highlight female strength and emphasize the importance of women in bridging together the two communities. Through the narratives they tell that surpass temporal boundaries and implicitly through their writing as two female authors, the texts suggest that women are society’s mechanism of resistance to social barriers.
Categorizing Identity: Literary, Performative, and Legal Languages in Oscar Wilde’s Libel Trial vs the Marquess of Queensberry
Authors: Hook Fred
Published: April 2021

Wilde has been generally accepted as one of the first figures of the queer man that is now known, however, how he came to represent this identity has not been much discussed. While his criminal trials, which led to his eventual conviction of ‘gross indecency,’ undoubtedly played a strong part on his emerging portrayal as a gay man, his first trial involving a libel suit against the Marquess of Queensberry is little discussed in relation to the start of his downfall and portrayal as a gay man. Thus, this project looks at Oscar Wilde’s libel trial and its effects on the identity of the homosexual man. By looking at the language used in the libel trial and its use of The Picture of Dorian Gray as evidence, the project concludes that by using the interpretations of Wilde’s novel during the trial, the law created a concrete image of what ‘gross indecency between men’ was, and of the type of person who participated in it, using Wilde as a representative for this identity. The way that his identity was forged allows us to see that while homosexuality as a way of being began to take shape thanks to Wilde’s trial, it was still imbued with negative connotations and seen as pederastic, tying it to anxieties around child prostitution and trafficking of the 1800s. The development of this new identity and its portrayal betters the understanding of the vilification of Wilde during his downfall and his novel’s role in this.
Ein(Stein) on the Beach (in Egypt): ‘Syncopated Time’ and the Formation of a ‘Continuous Present’ in Philip Glass’ Akhnaten
Authors: Sivilotti Lorenzo
Published: April 2021

In her 1935 lecture Plays, Gertrude Stein identifies a problem at the heart of the theatrical experience, that “your emotion concerning [the] play is always either behind or ahead of the play at which you are looking and to which you are listening” (Stein 58), creating an emotive and cognitive asynchronicity between the audience and the work, which she terms “syncopated time” (Stein 58). At the heart of this disconnect is her observation that “plays are either read or heard or seen” (Stein 59); the audience’s difficulty navigating this trialectic relationship is largely responsible for their desyncing from the emotional time-sense of the work. As the theatrical medium involving perhaps the most complex interplay of reading, hearing, and seeing, opera is an excellent subject for the application of Stein’s theories.

 

This paper applies Stein’s questions of cognitive perception and emotional time to Akhnaten, Philip Glass’ third opera (which recently received its Metropolitan Opera premiere), in order to explore how the work navigates the problems which Stein identifies. This paper will argue that Glass’ iterative and ‘minimalist’ compositional style creates a synthesis of reading, hearing, and seeing to create a ‘continuous present,’ allowing the audience to remain in emotive and cognitive synchronicity with the work, and thus preventing them from falling into ‘syncopated time.’ In this way, contemporary opera offers novel approaches to the performative relationship between a work and its audience.

Educational Epidemic: A Study of the Academic Underachievement of Luso-Canadians
Authors: Alves Carley
Published: April 2021

The Luso-Canadian community has been subject to a multitude of unfortunate social injustices since the initial waves of mass migration between the 1950’s and 1970’s. A community which has historically contributed greatly to Canadian society, has been marginalized intergenerationally in both the academic and professional realms of Canadian society. The Luso-Canadian community, specifically in Toronto where the highest concentration resides, has historically been marked by high drop-out rates, overrepresentation in special education and remedial reading programs, and extremely low rates of post-secondary education. These barriers early in life have been identified by numerous sources as being the cause for various subsequent issues the Luso-Canadian community has faced including vast underrepresentation in other professional spheres of Canadian life. While numerous causes can be identified to explain the reasoning for these injustices, it is clear that legislative actions by the school boards and board of education must be taken to battle this issue and ensure that Luso-Canadians fulfill their full potential.
