Published: June 2022

Abstract: Women's safety has become a major concern in all parts of the world as a result of growing violence against them. They have become accustomed to being physically or mentally mistreated. Harassment at work and in public places is causing individuals to abandon their passions and goals. Although the government has passed various anti-harassment legislation, the rate of female harassment has not decreased. Being amoral support is the best approach to reduce violence (robbery, sexual assault, domestic violence, and so on) against them. As a result, the Women Safety Patrolling Robot will endeavour to ensure the safety of women. Existing systems use CCTV cameras to record incidents, but this is not a preventative strategy for women's protection, whereas the suggested patrolling robot will patrol in its assigned area and check for anonymous behaviours. As a result, the women's community will benefit more from the night patrolling robot. Keywords: Aurdino, Esp32 Cam, L293D Driver, Universal Motors, Embedded C Programming.
Parkinsons Disease Prediction Using Machine Learning
Authors: T Mohesh , K Gowtham , P Vijeesh , S Arun Kumar
Published: June 2022

Abstract: Diagnosis of Parkinson's disease (PD) is commonly based on medical observations and assessment of clinical signs, including the characterization of a variety of motor symptoms. However, traditional diagnostic approaches may suffer from subjectivity as they rely on the evaluation of movements that are sometimes subtle to human eyes and therefore difficult to classify, leading to possible misclassification. In the meantime, early non-motor symptoms of PD may be mild and can be caused by many other conditions. Therefore, these symptoms are often overlooked, making diagnosis of PD at an early stage challenging. To address these difficulties and to refine the diagnosis and assessment procedures of PD, machine learning methods have been implemented for the classification ofPD and healthy controls or patientswith similar clinicalpresentations.

Vaccines and Therapeutics: Quality System Approach to Clinical Applications
Authors: Aziz-Andersen Kaiser Jay
Published: June 2022

Molecular bio-science developments involve applications of mRNA vaccines focused on diagnostic, prophylactic, and therapeutic aspects of COVID-19 related infectious diseases. These applications offer potential solutions for many of the current challenges in treating virus related infectious diseases.  The goal of vaccine design and development is to manufacture and consistently produce a vaccine that is safe and effective. The vaccine discovery starts with design input in terms of identification of etiologic agent, immunogenicity, adjuvant, basic scientific concepts, non-clinical and clinical studies, and finally vaccine licensure (FDA approvals). The Lipid Nanoparticle Technology (LNT) for messenger RNA is being used for COVID-19 vaccines. This technology comprises of identifying and mapping signature features of the virus which encompasses the readability of the virus’s blueprint, its neutralization and activation processes in order to deliver antibody proteins to protect the vaccine recipients’ bodies from encounters with the virus. The administering regimens are studied in clinical research laboratory and study materials are tested in suitable bench testing and biological models projecting vaccine candidate’s prophylactic immune response that is safe and effective. The vaccine manufacturing process requires critical quality control points (CQCPs) monitoring in order to maintain the steriochemical and immunological characteristics of the vaccine molecules and enable production of the vaccine in increasingly dosage quantities for ultimate human use. These aspects of vaccine development are well integrated into the total vaccinology life cycle (TVLC) regulatory requirements. The ultimate regulatory safety and efficacy requirements of the vaccine are proven through phases of clinical trials (class I, II, and III studies). The final process for human use to produce safe vaccine is part of pivotal clinical trials and data under the US FDA’s premarket approval process for full-scale production and availability of safe vaccines for clinical use.

Published: June 2022

Background: Parastar is an agricultural insecticide formulation composed of two active ingredients; a pyrethroid lambda-cyhalothrin and a neonicotinoid imidachloprid used in Cameroon for vegetable protection. Previous studies showed reprotoxicity and neurotoxicity of this pesticide formulation. Momordica foetida Schumach. Et Thonn is a medicinal plant with potent antioxidant properties used traditionally in Cameroon for the treatment of several aliments. As farmers are currently exposed to Parastar pesticide formulation, this study was designed to evaluate the protective effect of M. foetida on behavioral impairment, motor incoordination and brain oxidative stress induced by subchronic administration of Parastar. Methods: The study was carried out using 40 Wistar male rats, divided into 5 groups of 8 rats each. The groups received a vehicle (distilled water; 10 mL/kg), Parastar alone (6.23 mg/kg), or concomitantly with M. foetida methanol extract (50, 100 and 200 mg/kg) for 60 days. The animals were submitted to behavioural tests including, beam walking test, open field test and forced swimming test. At end of the treatment, oxidative stress parameters and acetylcholinesterase activity were assessed in brain of each animal. Results: Parastar induced motor dysfunctions, anxiogenic like and depressive-like behaviours in the animals. The Parastar -induced alterations in behavior were all prevented by M. foetida extract. The plant extract alleviated Parstar-induced oxidative stress and alteration of cholinesterase activity, especially at the dose 100mk/kg. Conclusion: Results from this study suggest that, M. feotida methanol extract may prevent anxiety-like behavior, depressive-like behavior, motor incoordination induced by Parastar, possibly through it antioxidant properties and the preservation of acetylcholinesterase activity.

Published: June 2022

Background: Resistant hypertension is a common medical challenge facing clinicians and specialists. Although, the prevalence is currently unknown but various clinical trials have suggested that this problem is not rare. Resistant hypertension is blood pressure that remains above goal despite the use of at least three antihypertensive agents including a diuretic. It is a subtype of hypertension that increases the risk of cardiovascular, cerebrovascular and kidney disease. However, it is important to distinguish between pseudo-resistant hypertension and apparent hypertension from true resistant hypertension as they are often misdiagnosed.
Objectives: This review focuses on resistant hypertension, its pathophysiology and established therapy.
Methodology: Relevant articles used for this review covered a period of 2008-2022 using search engines and databases including PubMed, Scopus, Web of Science, and Google Scholar.
Main observation: Evaluation of patients with true resistant hypertension includes appropriate blood pressure measurement, screening for causes of secondary hypertension and screening for interfering medications. Management of resistant hypertension that has proved successful includes non-pharmacological approach like lifestyle modification and optimization of pharmacological agents, often including the use of mineralocorticoid receptor antagonist.
Conclusion: Considering the future management of resistant hypertension, a bunch of new device-based therapies are under effective development. Of these, renal denervation and carotid baroreflex activation are two potential devices for the significant reduction of blood pressure. However, further study is necessary before these devices can be approved for the routine treatment of resistant hypertension.

Mucoadhesive drug delivery systems are very widely functional approach for delivery of system within the lumen of GIT to enhance drug absorption through the part of stomach with specific manner. Quinapril hydrochloride is the hydrochloride salt of quinapril, the ethyl ester of a non-sulfhydryl, angiotensin-converting enzyme (ACE) inhibitor, quinaprilat. The quinapril hydrochloride microspheres was prepared with a coat consisting of alginate polymer i.e. sodium alginate in combination of mucoadhesive polymer chitosan/ guargum by an ionic gelation process. The microspheres were evaluated for morphological character, particle size, micromeritic properties, percentage entrapment efficiency, in-vitro wash-off test and in-vitro release studies. The drug quinapril hydrochloride was study for the release over 24 h duration.  The retarding nature of system maximizing the medication discharge rate at the appropriate site within specified time period for enhancing the bioavailability of drug at desired site of action to give successful treatment to the patients experiencing hypertension The drug release of the microspheres (QLMM1 – QLMM10) was slow, extended and dependent on the composition of galactomannan concentration of polymer and stirring speed during formulation used. The mucoadhesive microspheres were adhered at intestinal pH due to highly swelling nature of composition of polymers at this pH. So, increase the adhesive strength and retarded the drug release of best composition of CH:GG in the ratio of 1:3 (QLMM6). Guargum is a highly viscous material having a property of more swelling nature due to presence of galactommannan constituent. Thus, drug release from QLMM6 was slow and extended over a period of 24 h and these microcapsules were found suitable for oral controlled release formulations.

Authors: Vivek Kumar Jha  , Rajbir Singh
Published: June 2022

The normal sense of hearing is essential in the social, emotional, psychological and communicative fields. It is needed for safety and also for having a more meaningful life. Causes of hearing loss in adults can be genetic or due to immune diseases, infections such as meningitis, mumps, scarlet fever, Meniere's disease, exposure to loud noises, tumors, head injuries or aging (presbycusis). The word "presbycusis" implies a decrease in hearing associated with the phase of degenerative cochlear aging. Presbycusis is by definition bilateral, symmetric and incremental. Presbycusis can affect on an individuals’ quality of life (QOL). Therefore, the main aim of the research is to evaluate the Impact of hearing loss on QOL (Quality of Life) in Adults.   Total 100 subjects were taken for this study. Out of 100 subjects, 50 subjects were taken as control group and 50 subjects were taken as experimental group and diagnosed to be hearing loss (Severe sensorineural hearing loss). A 25-point sample developed from the initial HHIE by Weinstein et al. The Hearing Handicap Inventory (HHIA)11 is often consisting of a 13-point emotional subscale and 12-point  social-situational  subscales.  Further,  the study concluded  that  in an effort to remedy its growth,  we need to strengthen our understanding of this disease and its physiopathology. Furthermore, developing approaches to recognise and deteriorate Presbycusis patients would be of considerable significance, thus expanding the resources provided for hearing aids, assisting communication systems and auditory therapy. Individuals of hearing damage, the use of effective hearing aids or other hearing aids, and education strategies may have a favourable influence on older people's quality of life.

Published: June 2022

Smartphones today help people accomplish daily activities, from simple tasks such as taking a reminder, to more complicated processes such as predicting road traffic while driving. However, performing complicated processes on smartphones cost the device’s energy to drain much faster. As an effect, the phone’s main purpose which is to enable communication whenever it is needed is degraded in terms of performance. In relation to this problem, researchers have tried to mitigate smartphone’s energy usage. An area that has yet to be further explored, is on examining smartphone’s context while the user is travelling. This paper presents a method to mitigate smartphone’s energy usage by gathering its context and to analyze it using Fuzzy Inference technique whilst the user is driving and using navigational application at the same time. Our finding shows that using this method can improve smartphone’s battery lifespan at an average rate, ranging between 1.6% to 3.1% for every hour with up to 19% of energy saving. These results proved that analyzing smartphone using context-awareness and Fuzzy Inference can reduce smartphone’s energy usage whilst the user is travelling, which in turn improves the overall energy efficiency in smartphone.

Authors: M.Alshari Eissa , Azman Azreen , Doraisamy Shyamala , Mustapha Norwati , Alksher Mostafa
Published: June 2022

The discovery of an active feature extraction technique has been the focus of many researchers to improve the performance of classification methods, such as for sentiment analysis. Many of them have shown interest in using word embeddings especially Word2Vec as the features for text classification tasks. Its ability to model high-quality distributional semantics among words has contributed to its success in many of the functions. Despite the success, Word2Vec features are high dimensional that lead to an increase in the complexity of the classifier. In this paper, an effective method for feature extraction based on Word2Vec is proposed for sentiment analysis. The process discovers polarity clusters of the terms in the vocabulary through Word2Vec and opinion lexical dictionary. The features vector for each text is constructed from the polarity clusters, which lead to a lower-dimensional vector to represent the text. This paper also investigates the effect of two opinion lexical dictionaries on the performance of sentiment analysis, and one of the dictionaries are created based on SentiWordNet. The effectiveness of the proposed method is evaluated on the IMDB with two classifiers, namely the Logistic Regression and the Support Vector Machine. The result is promising, showing that the proposed method can be more effective than the baseline approaches.
MULTI-RAT BASED ADAPTIVE QUALITY OF SERVICE (QOS) MANAGEMENT IN WBAN
Authors: Irshad Tayyaba , Shan Rafi-us , Ahmad Raja Wasim , Khalid Abbas , Ab Hamid Siti Hafizah
Published: June 2022

Wireless body area network (WBAN), a sub-branch of wireless sensor networks (WSN), helps continuous monitoring of various conditions and states of a human body. It has vast application areas, including self-care, battlefield, health, sports, assisted living, and entertainment. In WBAN, sensors (e.g., ECG, EEG, EMG, and temperature) may transmit sensed information of the subject under observation to a personal server which directs it to the main server for the analysis. The requirement of an application in terms of reliability and delay varies depending on the situation and environment. For instance, the high network delay and jitter for a health application may lead to a human death due to urgent response requirement. The major challenge faced by WBAN is to offer high Quality of Service (QoS). To ensure high QoS in WBAN, different techniques are proposed but all these techniques have considered different layers for different radio technologies. The current study put forwards an adaptive Multi-Radio Access Technologies (multi-RAT) based platform for the WBAN. Multi-RAT proposes a convergence/adaptation layer to entertain increasing request rate of WBAN applications. As a result, throughput, delay, and blocking probability for each request are minimized.
SENTIMENT ATTRIBUTION ANALYSIS WITH HIERARCHICAL CLASSIFICATION AND AUTOMATIC ASPECT CATEGORIZATION ON ONLINE USER REVIEWS
Authors: Win Myat Noe , Ravana Sri Devi Ra , Shuib Liyana
Published: June 2022

Due to COVID-19 pandemic, most physical business transactions were pushed online. Online reviews became an excellent source for sentiment analysis to determine a customer's sentiment about a business. This insight is valuable asset for businesses, especially for tourism sector, to be harnessed for business intelligence and craft new marketing strategies. However, traditional sentiment analysis with flat classification and manual aspect categorization technique imposes challenges with non-opinionated reviews and outdated pre-defined aspect categories which limits businesses to filter relevant opinionated reviews and learn new aspects from reviews itself for aspect-based sentiment analysis. Therefore, this paper proposes sentiment attribution analysis with hierarchical classification and automatic aspect categorization to improve the social listening for diligent marketing and recommend potential business optimization to revive the business from surviving to thriving after this pandemic. Hierarchical classification is proposed using hybrid approach. While automatic aspect categorization is constructed with semantic similarity clustering and applied enhanced topic modelling on opinionated reviews. Experimental results on two real-world datasets from two different industries, Airline and Hotel, shows that the sentiment analysis with hierarchical classification outperforms the classification accuracy with a good F1-score compared to baseline papers. Automatic aspect categorization was found to be able to unhide the sentiment of the aspects which was not recognized in manual aspect categorization. Although it is accepted that the effectiveness of aspect-based sentiment analysis on flat classification and manual aspect categorization, none have assessed the effectiveness while using hierarchical classification with a hybrid approach and automatic aspect categorization.
RESERVOIR COMPUTING WITH TRUNCATED NORMAL DISTRIBUTION FOR SPEECH EMOTION RECOGNITION
Authors: Ibrahim Hemin , Loo Chu Kiong
Published: June 2022

Speech is an effective, quick, and important way for communicating and exchanging complex information between humans. Emotions have always been a part of normal human conversation which makes the speech more attractive. Because of this major role of both speech and emotion, many researchers are inspired by studying Speech Emotion Recognition (SER) which still has plenty of challenges. In this study, we proposed a novel reservoir computing approach with the initialization of random connection weights for the input weight by the truncated normal distribution. Furthermore, Population-Based Training (PBT) is adopted to optimize the hyperparameters of the whole Echo State Network (ESN) model which have a significant impact on the model performance. The proposed model has adopted bidirectional reservoir input to increase the memorization capability, and Sparse Random Projection (SRP) was applied for dimensional reduction as a simple, unsupervised, and low complexity approach. The speaker-independent strategy was employed on EMODB and SAVEE datasets as an acted speech emotion dataset and Aibo as a non-acted dataset. The model achieved 84.8%, 65.95%, and 45.99% unweighted average recalls on the EMODB, SAVEE, and Aibo datasets respectively. The results show that the proposed model outperforms the recent state-of-the-art studies with a cheaper computational cost.

Introducción: típicamente, cuando se menciona la perforación esofágica secundaria a barotrauma como el mecanismo fisiopatológico causal de la perforación, la literatura se refiere a la perforación esofágica espontánea o síndrome de Boerhaave como entidad, la cual hace referencia a la ruptura longitudinal y transmural del esófago (previamente sano) secundaria a un aumento abrupto de la presión intraluminal esofágica, que se desencadena frecuentemente durante el vómito. Sin embargo, en la literatura médica existen algunos reportes que mencionan otros mecanismos de barotrauma diferentes a esta entidad.

Reporte de caso: se presenta el caso de una paciente de 64 años con antecedente de adenocarcinoma gástrico manejado quirúrgicamente (gastrectomía total y anastomosis esofagoenteral), quien presentaba estenosis de anastomosis esofagoyeyunal, que requirió un protocolo de dilatación endoscópica con balón CRETM. Se llevó a una tercera sesión de dilatación endoscópica, en la que durante la extracción del endoscopio se identificó una laceración esofágica profunda con perforación de 4 cm de longitud a nivel del esófago medio (8 cm proximal a anastomosis dilatada), y se sospechó del mecanismo de barotrauma como agente causal. Requirió traslado urgente a sala de cirugía, en la que se realizó esofagorrafia por toracoscopia, cubrimiento antimicrobiano empírico de amplio espectro y nutrición enteral por sonda avanzada durante la vigilancia intrahospitalaria. El esofagograma de control a los 7 días mostró una pequeña fuga sobre el área anastomótica, la cual se manejó de manera conservadora. El control imagenológico a los 14 días evidenció una disminución del tamaño de la fuga, con una evolución satisfactoria y tolerancia a la vía oral, y posteriormente se dio el egreso.

Published: June 2022

Introducción: la prevalencia e incidencia de la alergia alimentaria gastrointestinal ha aumentado en los últimos años, con importantes costos asociados, pero usualmente de buen pronóstico; sin embargo, en Colombia la información es escasa. Los objetivos del presente estudio son describir variables demográficas, sintomatología, clínica, estado nutricional, manejo e historia natural de la enfermedad; conocer su prevalencia en la población pediátrica colombiana por grupo etario, y describir sus costos directos.

Materiales y métodos: el estudio se desarrolló en 3 fases: en la primera, se estimó la prevalencia de la enfermedad a partir de la revisión de las bases RIPS y MIPRES de 2015 a 2019; en la segunda, se revisaron las historias clínicas seleccionadas por los criterios de inclusión y exclusión para caracterización y costos; y en la tercera, por medio de una encuesta telefónica se interrogó el estado actual de la enfermedad y su resolución.

Resultados: la prevalencia estimada ajustada por subregistro fue de 0,04 % para la población pediátrica y de 0,148 % para los menores de 5 años. Los diagnósticos más frecuentes fueron proctocolitis alérgica (59,3 %) y trastornos gastrointestinales funcionales secundarios (13,9 %). El alérgeno más frecuente fue la proteína de leche de vaca. El manejo temprano está relacionado con buen pronóstico nutricional. Los costos directos se relacionan principalmente con el uso de fórmulas (92 %) y consultas médicas (3,4 %). El 89 % de los padres considera la resolución de la alergia a través del tiempo.

Conclusiones: este es el estudio retrospectivo más grande en Colombia, lo que permite conclusiones locales que pueden ser comparadas con otros países.
Direct and indirect pathways for the spread of African swine fever and other porcine infectious diseases: An application of the mental models approac
Authors: Galli Francesco , Friker Brian , Bearth Angela , Duerr Salome
Published: June 2022

In this study, we investigated the occurrence of direct and indirect
infectious disease transmission pathways among pig farms in Switzerland,
as well as their specific relevance for the spread of African swine
fever, porcine reproductive and respiratory syndrome (PRRS), and
enzootic pneumonia. Data were collected using an adapted mental models
approach, involving initial interviews with experts in the field of pig
health and logistics, semi-structured interviews with pig farmers, and a
final expert workshop, during which all identified pathways were graded
by their predicted frequency of occurrence, their likelihood of spread
of the three diseases of interest, and their overall relevance
considering both parameters. As many as 24 disease pathways were
identified in four areas: pig trade, farmer encounters, external
collaborators, and environmental or other pathways. Two thirds of the
pathways were expected to occur with moderate-to-high frequency. While
both direct and indirect pig trade transmission routes were highly
relevant for the spread of the three pathogens, pathways from the
remaining areas were especially important for PRRS due to higher spread
potential via aerosols and fomites. In addition, we identified factors
modifying the relevance of disease pathways, such as farm production
type and affiliation with trader companies. During the interviews, we
found varying levels of risk perception among farmers concerning some of
the pathways, which affected adherence to biosecurity measures and were
often linked to the degree of trust that farmers had towards their
colleagues and external collaborators. Our findings highlight the
importance of integrating indirect disease pathways into existing
surveillance and control strategies and in disease modelling efforts. We
also propose that biosecurity training aimed at professionals and risk
communication campaigns targeting farmers should be considered to
mitigate the risk of disease spread through the identified pathways.

Objectives To study effects of physiotherapist-guided pelvic floor
muscle training on pelvic organ prolapse (POP) early postpartum period.
Design Assessor-blinded, randomized controlled trial. Setting
Physiotherapy Clinic, Reykjavik. Sample Eighty-four primiparous women
with a singleton delivery. Methods Participants were screened for
eligibility 6-13 weeks postpartum. Women randomized to the training
group conducted 12 weekly individual sessions with a physiotherapist,
starting on average 9 weeks after childbirth. Outcomes were assessed
after the last session (short-term) and at 12 months postpartum
(long-term). The control group received no instructions after the
initial assessment. Main outcome measures Self-evaluated POP symptoms by
the Australian Pelvic Floor Questionnaire. Results Forty-one and 43
women were randomized to the training and control groups, respectively.
At recruitment, 17 (42.5%) of the training and 15 (37%) of the control
group reported prolapse symptoms (p=0.6). Five (13%) from the training
and 9 (21%) controls were bothered by the symptoms (p=0.3). There was a
gradual decrease in the number of women with symptoms and no significant
short-term (p=0.08 at 6 months) or long-term (p=0.6 at 12 months)
differences between the groups regarding rates of women with POP
sympoms. No difference was between groups regarding bother in the short
(p=0.3) or longer term (p=0.4). Repeated measure analyses using Proc
Genmod in SAS did not indicate a significant effect of the intervention
over time, p>0.05. Conclusions There was an overall
decrease in postpartum symptoms of POP and bother during the first year.
Physiotherapist-lead pelvic floor muscle training did not change the
outcomes.
From “Brilliant study” to “One Woman’s outcry Against Her Nature”: “The Second Sex” in the 1950s American Scientific Journals
Authors: Loncarevic Katarina , Simendic Marko
Published: June 2022

Simone de Beauvoir?s The Second Sex has been considered as one of the most crucial books that influenced the second wave feminists, who mobilized during the 1960s and 1970s new massive feminist movement in America. This article analyses reception of the book in the American scientific/academic journals, and in that way, contributes to the field of periodical studies. This article, first, analyses post-war American context with the focus on status and role of women in the society, and then, moves on to enquire into the reception of The Second Sex in five American scientific journals, published during 1953 and 1954. The political context is intertwined with the absence of the critical reflexion among the first American authors who wrote about The Second Sex regarding the role of women in the 1950s America. The article analyses the language, key topics for the authors of critiques (that the book is primarily French; that it cannot apply to American women and context; that the book is non-scientific, despite the publisher?s promotion, and that it does not provide directions for the social changes Beauvoir calls for; and finally, that the book has problematic arguments regarding motherhood and the status of married women).
The Role of Valuation Specialists in Audits of Fair Values and Potential for Change under Amended Public Company Accounting Oversight Board Standards
Authors: Griffith Emily E. , Hammersley Jacqueline S.
Published: June 2022

The PCAOB recently implemented amended standards on the use of valuation specialists. We report interviews with 42 auditors and valuation specialists in which we describe the role of valuation specialists and problems during fair value audits under the original guidance. We evaluate whether the amended guidance will change practice and mitigate these problems. We find that specialists are more involved in fieldwork relative to planning and completion. Despite changes to communication and review requirements, specialists’ limited role in making conclusions relative to auditors will continue. Our analysis suggests the changes in standards are unlikely to meaningfully change practice. We expect little change because the amended standards will not increase specialists’ responsibility for outcomes or provide them additional guidance, they will not require auditors to acquire valuation knowledge, and they cannot reduce the inherent uncertainty in fair value settings. These issues underlie many of the problems in this area.
