Authors: Dnyanmote Santosh , Alio Jorge , Dnyanmote Anuradha 
Published: February 2021

Background:In view of the recent outbreak of the pandemic caused by novel corona virus 19 (n-covid) which has thrown the overall healthcare system that has created fear, apprehension and anxiety amongst all surgeons. Ophthalmic surgeons are no exceptions. The new corona virus is a respiratory virus of theCoronoviridaefamily containing a single strand of RNA which spreads primarily through droplets generated when an infected person coughs or sneezes or through droplets of saliva or discharge from the nose. A person can get infected by the virus if the person is within 1 meter of a person with COVID 19 or by touching contaminated surface and then touching eyes, nose or mouth.Methods:Standard recommendations to prevent the spread of COVID-19 include frequent cleaning of hands using alcohol based hand rubs or soap and water. Covering the nose and mouth with a proper mask, covering skin, eyes, hair, hands and legs with proper apparel is important.Just like elderly members of the society, the healthcare workers who have some co-morbidity are susceptible to COVID-19 invasion.Asymptomatic carriers who may present with senile or pre-senile cataract can be a potential source of infection to other patients, hospital staff, surgeons and others.Conclusion:It is important that all the microsurgical instruments which will be used for phacoemulsification be properly sterilized. The surfaces of these instruments should remain free of contaminants as these instruments will be used multiple times in other patients as well.

Authors: Kandil Faten , El Seesy Naglaa , Banakhar Maram 
Published: February 2021

Introduction:Insufficient research has been conducted into the factors that prompt young students to select nursing education as a profession in Saudi Arabia.Aim:The aim of the study is to identify factors affecting students' preference for nursing education and their intent to leave.Methods:This study follows a descriptive cross-sectional research design, with data collected by adapting the Tan-Kuick questionnaire to measure second-year nursing students’ (n=162) preference for nursing education and intent to leave one academic institution in Saudi Arabia.Results:Nursing image is identified as the major factor influencing the nursing students’ preference for nursing education in Saudi Arabia (69.89 ± 16.49), and parents' image of nursing is identified as the factor with the least amount of influence (34.52 ± 22.04). Additionally, more than half of the nursing students surveyed report intending to leave the nursing profession. Regarding the reasons for their intent to leave, a total of 70% of the surveyed nursing students report having no interest in the nursing profession. Family disagreement and societal image are also identified as common prompts to leave nursing.Conclusion:The study recommends the use of media to enhance the image of the nursing profession through the presentation of role models that talk to the students and encourage and motivate them to engage in the working life of a nurse. In addition, the study suggests replicating the longitudinal study for the same group in their third and fourth year of study to see if they leave the nursing profession.

Background & Aims:
The aim of this study was to assess IGF-1 in chronic liver diseases associated with HBV infection and describe the impact of liver status on IGF-1 variables.

Methods:
This cohort study included 348 subjects and conducted between December 2018 and December 2019 at El-Sahel Teaching Hospital, Cairo, Egypt. Subjects were divided into 4 groups: group I included HBV positive hepatocellular carcinoma patients “HCC” (n= 87), group II included HBV positive patients with liver cirrhosis “LC” (n = 87), group III included chronic hepatitis B (CHB) patients with neither HCC nor cirrhosis “CHB” (n = 87) and group IV of healthy volunteers as controls (n = 87). Serum IGF-1 was measured quantitatively using a commercially available enzyme immunoassay.

Results:
Serum levels of IGF-1 were measured in each of the 4 groups. The comparison showed marked differences in IGF1-related measures. It was found to be significantly reduced in HCC patients (32.08 ± 9.2 ng/ml), LC patients (50.6±14.1ng/ml) and CHB patients (61.4±14.3 ng/ml) in comparison to healthy subjects (140.4±49.9 ng/ml). The reduction of IGF-1 levels was also statistically significant between both HCC and LC patients and CHB patients also between HCC and LC patients.

Conclusion:
Serum IGF-1 levels are significantly reduced with the progression of hepatic disease in HBV patients and it may be a promising serological marker alone or in association with others for prediction of development of liver cirrhosis and HCC in chronic HBV patients.
Application of the National Institute for Health and Care Excellence Evidence Standards Framework for Digital Health Technologies in Assessing Mobile-Delivered Technologies for the Self-Management of Type 2 Diabetes Mellitus: Scoping Review
Authors: Forsyth Jessica R , Chase Hannah , Roberts Nia W , Armitage Laura C , Farmer Andrew J 
Published: February 2021

Background
There is a growing role of digital health technologies (DHTs) in the management of chronic health conditions, specifically type 2 diabetes. It is increasingly important that health technologies meet the evidence standards for health care settings. In 2019, the National Institute for Health and Care Excellence (NICE) published the NICE Evidence Standards Framework for DHTs. This provides guidance for evaluating the effectiveness and economic value of DHTs in health care settings in the United Kingdom.

Objective
The aim of this study is to assess whether scientific articles on DHTs for the self-management of type 2 diabetes mellitus report the evidence suggested for implementation in clinical practice, as described in the NICE Evidence Standards Framework for DHTs.

Methods
We performed a scoping review of published articles and searched 5 databases to identify systematic reviews and primary studies of mobile device–delivered DHTs that provide self-management support for adults with type 2 diabetes mellitus. The evidence reported within articles was assessed against standards described in the NICE framework.

Results
The database search yielded 715 systematic reviews, of which, 45 were relevant and together included 59 eligible primary studies. Within these, there were 39 unique technologies. Using the NICE framework, 13 technologies met best practice standards, 3 met minimum standards only, and 23 technologies did not meet minimum standards.

Conclusions
On the assessment of peer-reviewed publications, over half of the identified DHTs did not appear to meet the minimum evidence standards recommended by the NICE framework. The most common reasons for studies of DHTs not meeting these evidence standards included the absence of a comparator group, no previous justification of sample size, no measurable improvement in condition-related outcomes, and a lack of statistical data analysis. This report provides information that will enable researchers and digital health developers to address these limitations when designing, delivering, and reporting digital health technology research in the future.
PSEUDO-MULTIVARIATE LSTM NEURAL NETWORK APPROACH FOR PURCHASE DAY PREDICTION IN B2B
Authors: Ćirić Milica , Predić Bratislav 
Published: February 2021

This research focuses on trying to predict the moment of the next purchase for a customer in vendor-customer B2B scenario using an LSTM neural network and comparing prediction results from different input features. In a previous research we performed predictions for a specific customer product pair and used previous purchases for that pair as input data, but the number of such previous purchases was often very limited which resulted in low accuracy of predictions. By aggregating purchase data for all products a customer purchased, we were able to get more precise predictions of the next purchase. Additionally, expanding our input feature set yielded even better results. We performed an evaluation of LSTM networks trained with the most successful combination of input features for a six month period. Each of the networks was trained with purchase data up to the starting point of the selected period and the predictions were performed, after which additional input for the following seven days was added to the network. This process was then repeated for the entire six month period and a slight downward trend can be noticed for error metrics, leading to the conclusion that the network would perform even better over time with the addition of future purchases.
Exploring Teachers’ Perception of Online Engagement in Higher Education in New Zealand
Authors: Mani Krishan 
Published: February 2021

Student retention in higher education online learning is important for most education institutes around the world. Understanding what contributes to good learning engagement and key factors affecting engagement is important in improving online engagement. Online learning engagement is a very broad topic with multidimensional and interrelated factors that affect how engagement evolves. This study investigated higher education teachers’ perceptions of what online engagement means. It examined the importance of teachers' perceptions of online engagement in higher education with a focus on how teachers’ perceptions of engagement compare and the importance they placed on factors that help them identify the different forms of engagement. The study also explored whether the teachers’ perspectives were similar in terms of what equates to good learner engagement and what good engagement results into.
An extended literature review was carried out to inform the research. As the study eventually aims to gather responses about engagement from both learners and teachers, the methodology for the project was Case Study. Yin (1989, p.13)) explains that this approach is consistent when “the focus is on a contemporary phenomenon within some real-life context”. A survey using Microsoft 365 forms was conducted among higher education teachers with online teaching experience in various education disciplines in New Zealand.
The Findings from this initial step showed first, there are various definitions, and each teacher had a slightly different perspective of what engagement involved. The study also highlighted the similarities and gaps in terms of online engagement from a teacher’s point of view.

The study findings indicated, a consensus approach of understanding about what online engagement means and the strategies used by the teachers to foster engagement. The findings also suggested first, how motivation to learn, technology and access plays an important role with online engagement. Second, how the flexibility of online learning is differentiated from face to face teaching environments and the importance of adopting newer strategies for online engagement. Third, findings suggest that there are some offline learning with no visibility of engagement and show that this affected the teacher’s perceptions in regards to student success.

Supporting STEAM learning through student-developed Mixed Reality (MR) experiences
Authors: MacCallum Kathryn 
Published: February 2021

Mixed reality (MR) provides new opportunities for creative and innovative learning. MR supports the merging of real and virtual worlds to produce new environments and visualisations where physical and digital objects co-exist and interact in real-time (MacCallum & Jamieson, 2017). The MR continuum links both virtual and augmented reality, whereby virtual reality (VR) enables learners to be immersed within a completely virtual world, while augmented reality (AR) blend the real and the virtual world. MR embraces the spectrum between the real and the virtual; the mix of the virtual and real worlds may vary depending on the application. The integration of MR into education provides specific affordances which make it specifically unique in supporting learning (Parson & MacCallum, 2020; Bacca, Baldiris, Fabregat, Graf & Kinshuk, 2014). These affordance enable students to support unique opportunities to support learning and develop 21st-century learning capabilities (Schrier, 2006; Bower, Howe, McCredie, Robinson, & Grover, 2014).

In general, most integration of MR in the classroom tend to be focused on students being the consumers of these experiences. However by enabling student to create their own experiences enables a wider range of learning outcomes to be incorporated into the learning experience. By enabling student to be creators and designers of their own MR experiences provides a unique opportunity to integrate learning across the curriculum and supports the develop of computational thinking and stronger digital skills. The integration of student-created artefacts has particularly been shown to provide greater engagement and outcomes for all students (Ananiadou & Claro, 2009).

In the past, the development of student-created MR experiences has been difficult, especially due to the steep learning curve of technology adoption and the overall expense of acquiring the necessary tools to develop these experiences. The recent development of low-cost mobile and online MR tools and technologies have, however, provided new opportunities to provide a scaffolded approach to the development of student-driven artefacts that do not require significant technical ability (MacCallum & Jamieson, 2017). Due to these advances, students can now create their own MR digital experiences which can drive learning across the curriculum.

This presentation explores how teachers at two high schools in NZ have started to explore and integrate MR into their STEAM classes. This presentation draws on the results of a Teaching and Learning Research Initiative (TLRI) project, investigating the experiences and reflections of a group of secondary teachers exploring the use and adoption of mixed reality (augmented and virtual reality) for cross-curricular teaching. The presentation will explore how these teachers have started to engage with MR to support the principles of student-created digital experiences integrated into STEAM domains.

Distribution, population densiti and behavior in the space of ermine (Mustela erminea L.) in conditions Roztotchya and Nadsyannya
Authors:   Yavorivskyi National Nature Park, Stelmakh S. 
Published: February 2021

Peculiarities of distribution, population density and spatial behavior of ermine in the winter season in the natural regions of Roztotchya and Nadsyannia have been studied. About 60 % of the district’s territory lies within the hilly region of Roztocko-Opil, in particular Roztocze, the other part belongs to Prykarpattia, namely the Nadsyan plain. Methods of tracking and accounting of traces on snow were used. Population density calculations were performed according to the updated formula Formozova. The results of research have shown that the ermine is a fairly common species on both the Roztoc Upland and the Nadsyan Plain. However, the habitats of this predator mostly cover aquatic habitats (67 %). The best stations are primarily the coastal strip of small rivers and streams. In second place in terms of the number of registered traces of the species is the border of forests and arable fields, or meadows (20 %). In large forests, the species is mostly registered on fellings and young forest crops (8 %). In fields more than 500 m away from forests and water bodies, ermine is rare (3 %). Occasionally ermine is registered in settlements – near buildings (2 %). The highest population density of the species was observed in 2010 (8 individuals / 1000 ha). The lowest rates were registered in 2012 (2 individuals / 1000 ha). On average, the amplitude of fluctuations in ermine population density for 10 consecutive years reached 4 times the value. However, in coastal stations, the difference between the extreme indicators was 6 times (2–12 individuals / 1000 ha). The length of the daily course of ermines in winter is from 200 m to 4.5 km, on average 1.2 km. The average size of a single area of ​​the animal along the shores of reservoirs is 15–20 hectares, in the depths of the forest can be 100 hectares or more. Individual areas of males are slightly larger than females and are often superimposed on them. Instead, individual areas of males or females that live nearby almost never overlap. Some ermines can lead a nomadic lifestyle. The species is often active during the light period of the day.
