New Artificial Neural Network Models for Bio Medical Image Compression
Authors: Kumari G. Vimala , Rao G. Sasibhushana , Rao B. Prabhakara
Published: September 2021

This article presents an image compression method using feed-forward back-propagation neural networks (NNs). Marked progress has been made in the area of image compression in the last decade. Image compression removing redundant information in image data is a solution for storage and data transmission problems for huge amounts of data. NNs offer the potential for providing a novel solution to the problem of image compression by its ability to generate an internal data representation. A comparison among various feed-forward back-propagation training algorithms was presented with different compression ratios and different block sizes. The learning methods, the Levenberg Marquardt (LM) algorithm and the Gradient Descent (GD) have been used to perform the training of the network architecture and finally, the performance is evaluated in terms of MSE and PSNR using medical images. The decompressed results obtained using these two algorithms are computed in terms of PSNR and MSE along with performance plots and regression plots from which it can be observed that the LM algorithm gives more accurate results than the GD algorithm.
Disability as a Social Justice Imperative
Authors: Moore Adam
Published: September 2021

Educators in the United States have the legal obligation to ensure that students with disabilities are given equitable access to an education. Under the Individuals with Education Act (2004), Section 504 of the Rehabilitation Act (1973), and the Americans with Disabilities Act (1990), individuals with disabilities cannot be discriminated against based on their disability and must be provided the same educational opportunities as their non-disabled counterparts. While most teacher preparation programs as well as educators in higher education are knowledgeable of these laws, there is a striking absence of learning about the historical implication of segregation, abuse, and maltreatment of individuals with disabilities that led to these laws being enacted. Most teacher preparation programs do not teach future educators about the history regarding disability rights and the social construct of disability. This chapter will present the major theoretical and historical movements in the disability rights movement, as well as the practical implications for educators today.
Gendered Understanding of Disability and Aging
Authors: Bezbaruah Vaijayanti , Mehrotra Nilika
Published: September 2021

In its early conventional sense, disability was largely understood in bio-medical model which subsequently was supplemented with the psycho-social underpinnings of disability. In recent times, the social identities in terms of race, religion, class, caste, and gender add other dimensions to the social science discourse on disability studies. The chapter attempts to inform through the dimensions of age and aging in relation to the disability discourse, drawing from ethnographic cases over a period of research in North India. In the process, this chapter offers an analysis of disability and aging with focusing on the lack of access to social and familial resources for people with disability who are old and people who acquire any kind of disability in their old age. This chapter examines uncertainties experienced by the older disabled and the disabled older persons in relation to the extent of family ties and other social resources in both the rural and urban context.

Enhancing Disability Determination Decision Process Through Natural Language Processing
Authors: Amer Eslam
Published: September 2021

In this article, a new approach is introduced that makes use of the valuable information that can be extracted from a patient's electronic healthcare records (EHRs). The approach employs natural language processing and biomedical text mining to handle patient's data. The developed approach extracts relevant medical entities and builds relations between symptoms and other clinical signature modifiers. The extracted features are viewed as evaluation features. The approach utilizes such evaluation features to decide whether an applicant could gain disability benefits or not. Evaluations showed that the proposed approach accurately extracts symptoms and other laboratory marks with high F-measures (93.5-95.6%). Also, results showed an excellent deduction in assessments to approve or reject an applicant case to obtain a disability benefit.
The Impact of Assistive Technologies on Quality of Life and Psychosocial Well-Being
Authors: Schwartz Michael R. , Oppold Paul
Published: September 2021

Health-related quality of life is a comprehensive term to describe a person's experiences of health and illness. Quality of life (QOL) is a dynamic psychological construct encompassing interacting subjective and objective dimensions; thus, it is not directly observable. There is no gold standard for measuring quality of life due to the differing interests of doctors, caregivers, patients, and researchers. This chapter examines the research needs in the area of improving QoL through the proper implementation of AT. The authors also make recommendations for incorporating the needs of users and caregivers in the design, deployment, and use of AT to reduce device abandonment.

Published: September 2021

The Accessibility for Ontarians with Disabilities Act (AODA) is a law mandating that organizations in Ontario must comply to accessibility standards for people with disabilities. However, there is no tool to report accessibility complaints and track them. To that effect, mobile applications can be effective to make report and monitor accessibility issues as they arise in private as well as public spaces (e.g. building, sidewalks). An App would provide users with an opportunity beyond the mapping of compliance, it can provide data that addresses the gaps across legislation and embodied experiences. The objective of this paper is to share a novel method associated with the development accessibility monitoring Android App prototype called “ACCESS-ABILITY.” ACCESS-ABILITY is a first-of-its-kind app in the domain of disability informatics, it facilitates the formation of a collaborative virtual community that can be used by people with disabilities, advocacy groups, organizations and official bodies.
“Talk to Me!”
Authors: Cain Melissa , Fanshawe Melissa
Published: September 2021

As educators, we aim for students to seek, identify, and utilize a range of feedback to gain an understanding of their present performance in relation to learning goals, and ultimately to identify and use tools to close the gap between present and desired performance. We strive for all students to be their “own first assessors”—intelligent deciders—and develop the independence to self-assess the quality of their own work when they leave higher education institutions and enter the workforce. For students with a print disability such as vision impairment or blindness, traditional forms of feedback may not be successful in providing the information they need to close the gap. The most important issue for these students is access to feedback and agency in the feedback conversation. It is incumbent on higher education educators to find ways to provide equity of access to the provision and reception of feedback for all students. As such, this chapter explores ways for providing feedback to students with a vision impairment to ensure they are able to contextualize and utilize the feedback to improve learning outcomes. This is achieved by aligning the use of mobile technologies and audio feedback with the key principles of connectivism—autonomy, connectedness, diversity, and openness—to provide educators with recommendations.
IDEA and Inclusive Education
Authors: Grant Marquis C.
Published: September 2021

Federal mandates, most notably the Individuals with Disabilities Education Act (IDEA), guarantee education rights for children classified under one of the 13 categories of disabilities, ensuring that they are educated with their peers in the general education classroom as much as possible based on their ability and needs. State educational agencies and local educational agencies are responsible for ensuring that the pedagogical needs of all children with a disability are met in accordance with the law. This chapter discusses IDEA and the concept of inclusion and how special and general educators must increase their efforts to promote and support equitable opportunities for all students.

Authors: Hashim Aili Hanim , Sachdev Manveen Kaur , Bahar Norharlina , Ismail Wan Salwina Wan
Published: September 2021

There are many children with intellectual disability (ID) in recent years. The increase in numbers reflects the knowledge regarding the issue, thus creating awareness and increased detection for children for any developmental delay. Consequently, medical services are seeing and treating younger cohorts. Their disability may be mild to moderate, making it difficult even for medical professionals to identify these children. Invariably all parents want to have healthy, intelligent, and capable children who can achieve independence and a successful life. The reality is that parents having children with ID often struggle to understand what is happening with their child, what more how to cope with and help their child. Added to their distress is that even professionals dealing with the children and their family have various ideas and beliefs regarding this issue. Identifying families who are struggling and offering them the appropriate advice is essential as these families need proper guidance and services for their child.

Marsupials are one of three major mammalian lineages that include the placental eutherians and the egg-laying monotremes. The marsupial brushtail possum is an important protected species in the Australian forest ecosystem. Molecules encoded by the MHC genes are essential mediators of adaptive immune responses in virus–host interactions. Yet, nothing is known about the peptide presentation features of any marsupial MHC class I (MHC I). This study identified a series of possum MHC I Trvu-UB*01:01 binding peptides derived from wobbly possum disease virus (WPDV), a lethal virus of both captive and feral possum populations, and unveiled the structure of marsupial peptide/MHC I complex. Notably, we found the two brushtail possum–specific insertions, the 3-aa Ile52Glu53Arg54 and 1-aa Arg154 insertions are located in the Trvu-UB*01:01 peptide binding groove (PBG). The 3-aa insertion plays a pivotal role in maintaining the stability of the N terminus of Trvu-UB*01:01 PBG. This aspect of marsupial PBG is unexpectedly similar to the bat MHC I Ptal-N*01:01 and is shared with lower vertebrates from elasmobranch to monotreme, indicating an evolution hotspot that may have emerged from the pathogen–host interactions. Residue Arg154 insertion, located in the α2 helix, is available for TCR recognition, and it has a particular influence on promoting the anchoring of peptide WPDV-12. These findings add significantly to our understanding of adaptive immunity in marsupials and its evolution in vertebrates. Our findings have the potential to impact the conservation of the protected species brushtail possum and other marsupial species.

Authors: Abdalrazik Fatmaalzahraa S. , Bedair Nermeen I. , Yaseen Noha N.
Published: September 2021

Background

Chronic obstructive pulmonary disease (COPD) is characterized by exaggerated systemic inflammation that affects different body systems including the skin. Skin aging is a reported consequence.

Patients and methods

The study recruited 40 patients with COPD in addition to 60 healthy controls. Although all patients with COPD were smokers, controls comprised 27 smokers and 33 nonsmokers. Participants were classified according to their ages into younger age group (<40 years, n=37) and older age group (>40 years, n=63). All patients were subjected to careful history taking, thorough clinical examination, and pulmonary function testing at the time of skin biopsy. COPD diagnosis and grading of severity was based on the GOLD criteria. Dermatological examination included identification of skin type according to Fitzpatrick skin type classification, skin aging grade, and histopathological examination.

Results

In the younger group, COPD subgroup had significantly larger mean elastic fiber area, length, and perimeter when compared with the other two subgroups. In the older age group, the patients with COPD and control smokers’ subgroups had significantly larger total elastin fibers area when compared with nonsmokers. In both age groups, it was found that patients with severe/very severe COPD had significantly larger total elastic fibers area when compared with patients with moderate disease.

Conclusions

The present study found significant relation between skin aging and both smoking and COPD. The study noted that this relation may be affected by patients’ age.

Authors: Rathod Surekha Ramrao , Gonde Noopur Pradeep , Kolte Abhay Pandurang , Jadhav Ashwini Narendra
Published: September 2021

Background:

Maharashtra is one of the major hotspots affected with COVID-19 infection in India. By imposing lockdown to implement preventive and control strategies, entire world is trying to contain the spread of this potentially fatal pandemic. Lockdown has compelled people to stay at home, refrain from their day-to-day activity and lead to drastic lifestyle changes.

Aim:

The aim of the study was to assess the impact of COVID-19 pandemic lockdown on sleep-wake pattern and emotional status among Bachelor of Dental Surgery undergraduate students.

Materials and Methods:

This observational online survey was carried out among the undergraduate students of our dental college. The question on individual sleep cycle, wake up pattern, eating habits, working hours, screen time on T.V., mobile, and laptop were addressed before and during the lockdown. The results were tabulated and analyzed using the SPSS software version 17.0. If P < 0.001, the results were reported to be statistically significant.

Results:

Statistical difference was observed in the usage of digital media, change in their sleep wake pattern, and eating habits among dental students during the lockdown period after applying paired test with P < 0.001. Furthermore, these unpredictable changes in their working hour, sleeping pattern, eating habits, and concern about spending time build stressful situation among students.

Conclusion:

It can be concluded that the dental students have increased level of stress and disturbance in sleep-wake cycle and emotional well-being during this COVID-19 lockdown.
Disinfection in regenerative endodontics and effect of commonly used antimicrobials on stem cell fate
Authors: Rai Siddharth , Rangappa Anitha Kumari
Published: September 2021

The endodontic management of necrotic immature permanent teeth is often challenging for the clinician. Regenerative endodontic treatment has emerged as an important alternative to the traditional apexification treatment in such cases. In regenerative endodontics, elimination of microbes from the root canal is important for the survival, proliferation, and differentiation of stem cells. Translational studies suggest that irrigants and medicaments used for root canal disinfection may adversely affect stem cells and ultimately, the regenerative outcome. Conventionally, irrigants and medicaments have been chosen for their maximum antimicrobial effect without considering their effects on stem cells and the dentinal microenvironment. In this review, advances in disinfection for regenerative endodontics are discussed.
Reconstructing a COVID-19 outbreak within a religious group using social network analysis simulation in Korea
Authors: Kim Namje , Kang Su Jin , Tak Sangwoo
Published: September 2021

OBJECTIVES: We reconstructed a coronavirus disease 2019 (COVID-19) outbreak to examine how a large cluster at a church setting spread before being detected and estimate the potential effectiveness of complying with mask-wearing guidelines recommended by the government.METHODS: A mathematical model with a social network analysis (SNA) approach was used to simulate a COVID-19 outbreak. A discrete-time stochastic simulation model was used to simulate the spread of COVID-19 within the Sarang Jeil church. A counterfactual experiment using a calibrated baseline model was conducted to examine the potential benefits of complying with a mask-wearing policy.RESULTS: Simulations estimated a mask-wearing ratio of 67% at the time of the outbreak, which yielded 953.8 (95% confidence interval [CI], 937.3 to 970.4) cases and was most consistent with the confirmed data. The counterfactual experiment with 95% mask-wearing estimated an average of 45.6 (95% CI, 43.4 to 47.9) cases with a standard deviation of 20.1. The result indicated that if the church followed government mask-wearing guidelines properly, the outbreak might have been one-twentieth the size.CONCLUSIONS: SNA is an effective tool for monitoring and controlling outbreaks of COVID-19 and other infectious diseases. Although our results are based on simulations and are thus limited, the precautionary implications of social distancing and mask-wearing are still relevant. Since person-to-person contacts and interactions are unavoidable in social and economic life, it may be beneficial to develop precise measures and guidelines for particular organizations or places that are susceptible to cluster outbreaks.
Dengue and COVID-19 infections in the ASEAN region: a concurrent outbreak of viral diseases
Authors: Wiyono Lowilius , Rocha Ian Christoper N. , Cedeño Trisha Denise D. , Miranda Adriana Viola , Lucero-Prisno III Don Eliseo
Published: September 2021

Member countries of the Association of Southeast Asian Nations (ASEAN) have faced dengue outbreaks for decades, and the region has one of the highest rates of dengue globally. Outbreaks continue to occur concurrently with the coronavirus disease 2019 (COVID-19) pandemic in the 10 ASEAN countries. Both infectious diseases pose a tremendous burden in these countries related to both infection control and the economy. Increases in the number of dengue cases occurred in part due to disruptions in the pathogen-host-vector relationship caused by changes in human behaviour in response to the COVID-19 pandemic. The spread of dengue was further aggravated by the implementation of lockdowns and social distancing policies. These measures limited the coverage of dengue preventive programs and delayed the medical management of both diseases due to co-infection and misdiagnosis. It is of the utmost importance for the population to remain aware of both diseases, and dengue vector control strategies must be devised to properly address outbreaks using digitalization and remote surveillance. Similarly, critical triage algorithms and further research are also needed to combat co-infection and misdiagnosis. Controlling the spread of COVID-19 though vaccination should also be undertaken to reduce the impact of the pandemic.

Published: September 2021

The experiment evaluated the effects on the chemical composition (fermentation, kinetic parameters, and protein and carbohydrate fractions) of corn silage after various storage durations (45, 90, 180, and 360 days). Experimental mini silos of the corn plants were made and opened after various storage periods. The experimental design was completely randomized with four treatments and four replications per treatment. Variables such as pH, lactic acid and acetic acid showed a quadratic effect, whereas effluent and gas losses increased linearly with prolonged storage. Proteolysis was observed with an increase in storage, resulting in a rise in ammonia-N, soluble N, and non-protein N concentration and reduction in true protein. The soluble carbohydrate fractions were reduced, and digestible and indigestible fibre were increased. For the kinetic degradation parameters of the silages obtained through in vitro gas methodology, the highest fermentation rate occurred in the first 12 hours of incubation, and the highest volume of gas produced within 96 hours was obtained for silages with shorter storage (45 days). The increase in storage resulted in greater losses and lower ruminal degradability in vitro, causing a decrease in protein quality and nutritional value.

Large pig farms generate enormous volumes of wastewater without proper treatment before discharge. High-rate anaerobic reactors as the expanded granular sludge bed (EGSB) are rarely reported for that purpose. In this study, an EGSB reactor with Cuban natural zeolite addition was evaluated for treating piggery wastewaters at lab scale. This study was conducted at different organic loading rate (OLR) ranging from 0.32 to 6.13 gCOD/Ld with a constant hydraulic retention time (HRT) of 12 h. The evolution of several control and operational parameters as the soluble chemical oxygen demand (COD) demonstrated a proper bioreactor performance to treat piggery wastewater. The results showed that the addition of natural zeolite at 40 gzeo/Lreactor in EGSB reactor results in COD efficiencies over 70%, despite of the fluctuations of fed wastewater characteristics. The kinetic study demonstrates that, the modified Stover-Kincannon model was found to be appropriate for EGSB reactor. The effluent soluble COD was predicted with high determination coefficient. The maximum removal rate constant (Umax) and saturation value constant (KB) were reported for a first time for the EGSB reactor with values of 10.2 and 11.8 gCOD/Ld, respectively. Methane yield for both, batch and continues experiments, were in the range from 214.5 to 299.8 mLCH4/gCOD.
Regulating the monomer of polyhydroxyalkanoate from mixed microbial culture: with particular emphasis on substrate composition: A review
Authors: Wei Tong , Fang Qian
Published: September 2021

Polyhydroxyalkanoate (PHA), produced by mixed microbial cultures (MMCs), is a biodegradable biopolyester that alleviates the global plastic crisis in the nearest future. Even PHA has become a research hotspot, reviews on PHA composition determining thermodynamic and processing properties of PHA products are rare. The primary focus of the evaluation relies on the factors affecting the PHA monomer composition of MMC-PHA production. Besides, since the volatile fatty acids (VFAs) composition of the substrates strongly influences the PHA monomer composition, regulating the ratio of even-carbon to odd-carbon VFAs, PHA, vary properties could be obtained predictably. So oriented acid production process, the first stage process in three-stage MMC-PHA production that can regulate the VFAs composition, is also comprehensively introduced to help understand PHA monomer regulation.

In the $d$-dimensional hypercube bin packing problem, a given list of
$d$-dimensional hypercubes must be packed into the smallest number of hypercube
bins. Epstein and van Stee [SIAM J. Comput. 35 (2005)] showed that the
asymptotic performance ratio $\rho$ of the online bounded space variant is
$\Omega(\log d)$ and $O(d/\log d)$, and conjectured that it is $\Theta(\log
d)$. We show that $\rho$ is in fact $\Theta(d/\log d)$, using probabilistic
arguments.

Alleviation or Politicization of Poverty in Africa? A Critique of Nigeria’s Social Investments Programs under Buhari-led Administration, 2015-2020
Authors: Anthony Chinedu Ugwu  , Dr. Al Chukwuma Okoli
Published: September 2021

The study interrogates the politics of poverty alleviation amidst the prevalence of poverty in Africa, focusing on Nigeria. Nigeria currently ranks among the poor countries in the world. While many studies have examined aspects of poverty mitigation within the national development frameworks, the politics underlying such endeavors have been under-explored. This study narrows this gap by investigating how politicians bastardize social investment programs through tokenish material 'hand-outs' designed to serve immediate political ends. The study is based on textual and contextual analysis of secondary sources, as complemented by corroborated anecdotes. Appropriating Marxian production theory, the study posits that the prevalence of poverty in Africa has been occasioned by macro and micro-level politics. At the macro-level, the balance of trade cum balance of payment asymmetries has reproduced conditions that perpetuate dependency and underdevelopment in the developing countries in general and Nigeria in particular. At the micro-level, local politicians trivialize social investments by exploiting the poverty situation of the populace for electoral gains through ad hoc material 'hand-outs.' This has weakened the social investment policy environment and alienated the citizenry in decision-making concerning wealth creation, distribution, and social investments priorities. The study recommends mainstreaming social investment governance into national development programing for sustainability.

The widespread introduction of virtual computer simulations (VCS) in the educational process is limited by the tools’ market for their development. The created software shell consists of three functionally different modules: creating and editing video conferencing; use of videoconferencing; monitoring of the educational process. The developed software shell has remote access and can become the main tool for the repository of virtual computer simulations. Currently, videoconferencing in the field of cardiology has been created as a potential digital base for practical clinical studies and accreditation.
New Electronically Tunable Third Order Filters and Dual Mode Sinusoidal Oscillator Using VDTAs and Grounded Capacitors
Authors: Paul Tapas Kumar , Pal Radha Raman
Published: September 2021

This study introduces a third order filter and a third order oscillator configuration. Both the circuits use two voltage difference transconductance amplifiers (VDTAs) and three grounded capacitors. By selecting the input and output terminals properly, current mode and transimpedance mode low-pass and band-pass filters can be obtained without component matching conditions. The natural frequency (ω0) can be tuned electronically. The oscillator circuit provides voltage and current outputs explicitly. The condition of oscillation (CO) and the frequency of oscillation (FO) can be adjusted orthogonally and electronically. The workability of the configurations is judged using TSMC CMOS 0.18 μm technology parameter as well as commercially available LM13700 integrated circuits (ICs). The simulation results show that: for ±0.9V power supply, the power consumption is 1.08 mW for both the configurations, while total harmonic distortions (THDs) are less than 2.06% and 2.17% for the filter and oscillator configurations, respectively.

Published: September 2021

Background: The global pandemic has created a need for several higher education institutions to transition to emergency remote learning. Students and faculty have experienced a significant disruption to their daily academic routines. It is critical to understand the perceptions of students in relationship to their learning experiences and ability to effectively manage the new and changing learning environment and expectations. This study sought to understand the students’ response to the transition to remote learning, as a necessary strategy for managing learning during the pandemic. Methods: A 15-item electronic survey was provided to approximately 1600 students at a private faith-based university in Central Florida, United States. Results: The response rate of 38% indicated primary positive responses to the transition, with significant differences of comfort level of remote learning and perceptions of faculty readiness, when analyzed between undergraduate and graduate students.

Purpose: Falls are an emerging public health problem causing a cascade of medical, functional, and socio-economic consequences. Apart from other widely explored risk factors affecting balance, anthropometric factors are also known to have an impact on balance. However, this relationship hasn’t been studied extensively in older adults. This study aimed to evaluate the relationship between the anthropometric factors such as Body Mass Index (BMI), Body Fat Mass (BFM), Waist-Hip Ratio (WHR), Lower Limb Length (LLL), Foot Length (FL) and balance in the elderly among fallers and non-fallers. Method: This cross-sectional study was performed on 100 fallers and 100 non-fallers, aged 60 years and above. These participants were recruited by a stratified random sampling technique from Navi Mumbai region. All the above anthropometric factors were measured and recorded. Each participant’s balance was assessed using the Mini-BESTest scale. Obtained scores were analysed in SPSS software; descriptive statistics, Spearman correlation coefficient, and Z scores were applied. Results: A sample size of 100 non-fallers, 50% male and 50% females, participated in this study. Among those participants classified as “fallers,” 56% were males and 44% were females. The mean age of the non-fallers was 66±5.01 and the mean age of the fallers was 67.72±6.73. In fallers, WHR showed good negative correlation (r= -.807), BFM as moderate (r= -.577) and BMI as fair (r= -.426) whereas in non-fallers, BMI showed moderate (r= -.546) and fair negative correlation for both WHR (r= -.303) and BFM (r= -.441). However, LLL and FL in both groups show little or no correlation. The Association of all anthropometric factors with the balance between fallers and non-fallers showed no-significant difference. It may be inter-group variance for age, gender and BMI, as participants were not matched for these variables during the recruiting phase. Additionally, the reason for the fall was not explored, thus adding to the limitations of our study. Conclusion: This study demonstrated the impact of increased WHR, BFM and BMI on balance in the elderly fallers and non-fallers. Thus, it is important to screen these factors while assessing biological risk factors for predicting falls. This study further recommends exploring the normative value for anthropometric factors in a healthy elderly population.

This research paper aims to examine and critique the impact and contribution of HBCUs in advancing societal issues and education while fostering a heightened understanding of social justice for today’s HBCU students. The purpose of this research is to discuss, expose, and share the impact HBCUs have had on the “WOKE” movement and social justice in the United States of America. The discourse centers on the development of scholars and activities who have been nurtured by and at HBCUs. The primary sources and events have been summarizing, focusing on the cause and effect of the injustice minorities face from the modern Civil Rights Era to the present day. The information/data demonstrates core components that have shaped American HBCUs from their establishments/foundation. Those ideals still evoke the same emotion of individuals who effort toward higher education decades ago up to today’s HBCU student bodies that embrace societal images upon their school. It also demonstrates how HBCUs have shown their ways of waking to societal limits in multiple forms of action to be heard through their oppression. Some sources broadly state approaches to reinstating these essential values, while some indicate the efforts to prove the name of HBCUs compared to PWIs. Some sources even show how our institutions solidify our government. This paper expresses how HBCUs in our nation keep students aware of the delinquent acts around them from social injustice and racial inequality.
