El servicio de extensión acompañando la investigación para una mejor atención a los cafeteros de Colombia
Authors: Saldías Barreneche Carlos Alberto
Published: June 2022

En el año de 1928 la Federación inició la prestación de servicios a los caficultores a través de un servicio de Asistencia Técnica, el cual fue complementado en 1929 con la creación de la “Granja Escuela Central de Café”, con fines experimentales, demostrativos y de capacitación. Allí se formaron los primeros “Prácticos Cafeteros” quienes recorrían las zonas visitando las fincas llevando mensajes técnicos, para fomento del cultivo y mejoramiento de las plantaciones, así como programas sociales. Desde 1938 hasta 1959 la labor de asistencia técnica se amplió con el establecimiento de tres campañas básicas: Defensa y saneamiento de las plantaciones, conservación de suelos y beneficio del café, para lo cual se encontró un gran apoyo con la creación de Cenicafé (1938); adicionalmente se adelantaron programas complementarios de fertilización, granjas demostrativas y capacitación.

NASA's Double Asteroid Redirection Test (DART) mission is the first full-scale planetary defense mission. The target is the binary asteroid (65803) Didymos, in which the smaller component Dimorphos (∼164 m equivalent diameter) orbits the larger component Didymos (∼780 m equivalent diameter). The DART spacecraft will impact Dimorphos, changing the system’s mutual orbit by an amount that correlates with DART's kinetic deflection capability. The spacecraft collision with Dimorphos creates an impact crater, which reshapes the body. Also, some particles ejected from the DART impact site on Dimorphos eventually reach Didymos. Because Didymos’s rapid spin period (2.26 hr) may be close to its stability limit for structural failure, the ejecta reaching Didymos may induce surface disturbance on Didymos. While large uncertainties exist, nonnegligible reshaping scenarios on Didymos and Dimorphos are possible if certain conditions are met. Our analysis shows that given a surface slope uncertainty on Dimorphos of 45°, with no other information about its local topography, and if the DART-like impactor is treated as spherical, the ejecta cone crosses Didymos with speeds ≳14 m s−1 in 13% of simulations. Additional work is necessary to determine the amount of mass delivered to Didymos from the DART impact and whether the amount of kinetic energy delivered is sufficient to overcome cohesive forces in those cases. If nonnegligible (but small) reshaping occurs for either of these asteroids, the resulting orbit perturbation and reshaping are measurable by Earth-based observations.

Authors: Melastuti Erna , Nursalam Nursalam , Sukartini Tintin , Putra Made Mahaguna
Published: June 2022

BACKGROUND: Management of health problems in patients undergoing hemodialysis is quite complicated, fluid restriction, diet, following treatment recommendations, and managing physical activity are problems that are often difficult to manage. Self-regulation of HD patients is needed to maintain adherence regarding fluid restriction, diet, medication, and physical activity management.

AIM: We aimed to investigate self-care adherence in hemodialysis patients with a structural equation modeling.

METHODS: One hundred and thirty patients with the hemodialysis-dependent end-stage renal disease took part in a quantitative cross-sectional study.

RESULTS: The researchers investigated personality traits, information factors, emotional factors, disease representation, motivation, appraisal, coping, and self-care adherence.

CONCLUSION: Except for motivation, which has no direct effect on coping (T-statistic = 1.666), almost every construct in this model significantly affects coping.

Authors: Satibi Satibi , Kirana P Luthfi Kinanthi , Aziza P Mella , Hutasoit Monica , Pribadi Prasojo
Published: June 2022

Context: Since the implementation of the Universal Health Coverage (UHC) policy in Indonesia, the drug procurement system has changed to using the e-catalogue system. The impact of this policy change on the pharmaceutical industry in Indonesia is unclear and has not been widely studied.

Objectives: This study analyzes the impact of the UHC policy on drug pricing by the pharmaceutical industry in Indonesia.

Methods: This study collects data from 3 pharmaceutical industries that won the e-catalogue drug tender. Data on drug prices produced by these 3 industries in 2013 were taken from the Drug Price Ceiling List, while drug prices in 2015 and 2018 were obtained from the e-catalogue drug list. The drug price data is compared from year to year to see the trend of change and the magnitude of the change. Data were analyzed using a price index calculation adapted from the concept of Median Price Ratio (MRP) calculation to compare drug prices in 2013 with drug prices per each region in 2015 and 2018 in the Microsoft Excel Office application as a measuring tool.

Results: There was a change in drug prices from the era before UHC (in 2013) and after the UHC era (in 2015 and 2018). There are drugs that have increased in price and some have decreased in price. The price increase ranged from 0.01–6.15 in 2015 and 0.01–6.46 in 2018. The price decrease ranged between 0.04–0.75 in 2015 and 0.01–0.83 in 2018.

Conclusion: Drug prices from before the UHC era (2013 and 2015) to after UHC (in 2018) experienced a change in the form of an increase or decrease in price.

Authors: Ali Amir , Khan Abid Ullah , Algahtani Obaid , Saifullah Sayed
Published: June 2022

In this article, we study the nonlinear sine-Gordon equation (sGE) under Mittag-Leffler and exponential decay type kernels in a fractal fractional sense. The Laplace Adomian decomposition method (LADM) is applied to investigate the sGE under the above-mentioned operators. The convergence analysis is provided for the proposed method. The results are validated by considering numerical examples with different initial conditions for both kernels and confirm the competence of the proposed technique. It is revealed that the obtained series solutions of the model with fractal fractional operators converge to the exact solutions. The numerical results converge to the particular exact solutions, proving the significance of LADM for nonlinear systems under fractal fractional derivatives. The absolute error analysis between the exact and obtained series solutions with both operators is shown in the tabulated form. The physical interpretations of the attained results with different fractal and fractional parameters are discussed in detail.

Authors: Fu J. , Wu W.
Published: June 2022

The optimal process conditions of the advanced aqueous method for recovering oil and de-oiled meal from pumpkin seed kernels were: baking the kernels at 110 °C for 1 min, grinding them to pass through a sieve of 150 μm pore size, adding 1.60 ml brine to 10.00 g ground kernels, stirring for 30 min at 30 °C, centrifuging at 4000 r/min for 30 min and cold-pressing the residue from centrifugation. This method recovered > 94% oil. Its oil recovery rate was comparable to that of solvent extraction and higher than that of enzyme-assisted aqueous method or hot-pressing. It recovered edible oil with higher quality and level of coenzyme Q10, tocopherols, carotenoids, total phytosterols and squalene as compared to solvent extraction or hot-pressing and requirements of China’s national standard. It is superior to enzyme-assisted aqueous method or hot-pressing for recovering de-oiled meal which is suitable for making texturized protein.

Published: June 2022

Audiometric tests can identify the hearing loss at specific frequencies using the audiogram. The aim and objectives of the study were (i) to develop an automated audiometer for self-diagnosing the hearing ability of the patient; (ii) to extract the features from the acoustic signals and to classify the normal and profound hearing loss patients using different machine learning algorithms; (iii) to validate the hearing loss classification using six-frequency average (6-FA) method based on simple linear regression analysis and machine learning algorithms. The study is conducted among 150 patients, including 75 patients with normal hearing ability and 75 patients with profound hearing loss. The total population of 150 underwent audiometric test both in the soundproof audiometric room and in the normal field environment. Based on the patient response, the intensity and frequency are changed automatically, and the audiogram is plotted by the principle of Artificial Neural Network learning procedures. The overall accuracy produced by classification of normal and profound hearing loss patients using Support Vector Machine (SVM), k-Nearest Neighbor classifier, and Naïve Bayes classifier is 97%, 96%, and 95%, respectively. The results indicated that the SVM classifier outperforms the other two classifiers well. The preliminary audiometric test can be performed remotely and then consulted with an audiologist. Thus, the patient could operate the developed prototype independently and get a consultation from trained medical personnel.

Published: June 2022

In this digital health technology world, many health applications are being developed. Artificial intelligence (AI) plays an important role for such important. Popular AI techniques include ML for handling structured and unstructured data. Machine learning detects health issues by studying many health records and data of the patients, hence increasing the efficiency of detection of chronic diseases in the medical field. Medical information modeling is to predict the medical needs in future and is a representation of a complex system into a simplified representation. Diabetes is one of the major diseases in the world population. It is a chronic disease associated with abnormally high levels of glucose in the blood. Gestational diabetes is a temporary condition associated with pregnancy. Several parameters are considered for the study (i.e., age, BMI, insulin levels, BP, number of pregnancies, glucose levels, etc.). Results can be obtained by using machine learning approaches like logistic regression and naive bayes.
The relationship between quality of sleep, stress, depressive and anxiety symptoms and coping strategies among first-year female students of the University of Colombo, Sri Lanka
Authors: Thakshila S. , Suraweera C.
Published: June 2022

Background: Sufficient and restorative sleep is essential for mental and physical wellbeing. The challenges of university life may be associated with detrimental effects on students’ mental wellbeing, leading to stress and poor quality of sleep. Students may adopt varied strategies to cope with these difficulties.
Aims: The aim of this study was to explore the relationship between quality of sleep, stress, depressive and anxiety symptoms, and coping strategies, among first-year female students of the University of Colombo, Sri Lanka.
Methods: A cross-sectional study was conducted among 200 female undergraduates from five selected faculties of the University of Colombo, Sri Lanka. A selfadministered questionnaire, the Pittsburg Sleep Quality Index (PSQI), Depression Stress Anxiety Scale- 21 (DASS-21) and the Brief Coping Orientation to Problems Experienced Inventory (brief COPE inventory) were administered using simple random sampling.
Results: Among the participants, 82.5% (n=165) had poor objective and subjective quality of sleep as indicated by the global PSQI. There was a strong positive correlation between sleep quality and stress, and 57.6% (n=95) of the poor sleepers were found to be stressed. The occurrence of stress was positively correlated with the use of self-blame, planning, denial, and emotional support as coping strategies, as per the brief COPE inventory. There was also a statistically significant correlation between quality of sleep, as measured by the PSQI, and coping strategies, as measured by the brief COPE inventory. The highest mean global PSQI score was observed among students from the Faculty of Law, with 95% experiencing poor quality of sleep. The highest correlation between sleep quality and stress was seen among students from the Faculty of Medicine, where the highest percentage of students (61.9%), were stressed.
Conclusions: Most of the university undergraduates who participated in this study had poor quality of sleep and stress. There was a strong relationship between sleep quality, stress, and the type of coping strategy the undergraduates used.
Stigma among the stigmatized? Preferred social distance and associated factors among outpatients at a psychiatry clinic in Benin City, Nigeria
Authors: Osasona S. O. , Ofovwe C. E.
Published: June 2022

Background: Researchers, hitherto, have focused largely on public stigma towards people with mental illness; literature evidence appears inadequate on stigma and discrimination among the psychiatric patients themselves, creating a prominent gap in literature and limiting interventions that could improve tolerant attitude among them and successful treatment outcome.
Aims: To determine the prevalence of moderate to high social distance among participating psychiatric patients and elucidate the factors that are associated with desire for high social distance among them.
Methods: A descriptive cross-sectional design was employed and participants included psychiatric patients attending the out-patient clinic of a tertiary hospital in Benin City, Nigeria. Data was collected using a socio-demographic data collection sheet, The Bogardus Social Distance Scale, The World Psychiatric Association Stigma Questionnaire, and The Brief Psychiatric Rating Scale. Version 21 of SPSS was used to analyze the data at a statistically significant level of P< 0.05.
Results: The prevalence of moderate to high social distance was 67.8% and social distance had significant association with belief about heredity and evil spirit causation of mental illness (Chi2=4.858, P=0.025 and Chi2=5.947, P=0.015 respectively); belief about treatment outcome of mental illness (Chi2=15.796, P=<0.001), and belief that people with mental illness are dangerous (Chi2=7.367, P=0.007); all of which, apart from dangerousness, independently predicted moderate to high social distance among the patients.
Conclusion: The findings of this study presented an emerging evidence of high social distance and stigmatization among psychiatric patients towards one another akin to reported public stigma against them. Misconceptions that influence high social distance in the public are also shared by the patients. This development warrants conscious and concerted efforts to stem the tide.
A life skills intervention aimed at changing attitudes of Indian youth towards alcohol and drug abuse
Authors: Kaur J. , Singh D. , Joshith V. P.
Published: June 2022

Background:The misuse of ilicit drugs has become a very significant and challenging problem, worldwide. There has been significant increase in crime and violence across the world which may be associated with the illegal production and distribution of illicit drugs. According to a UN report, the number of people dependent on drugs in India is on the increase, indicating very difficult challenges ahead.
Aims: The present study explores the effectiveness of a life skills intervention to change the attitudes of youth towards alcohol and drug abuse, in the Punjab state of India.
Methods: A quasi-experimental design of research was used to conduct the study among a sample of 1000 first year college students from 6 randomly selected districts of Punjab, India. The scales used for measuring the attitudes of college students towards alcohol and drug abuse were developed for the purpose of this study.
Conclusions: The results of analysis of covariance revealed that life skills training had a significant effect on changing attitudes towards alcohol and drug abuse, among study participants. The findings from this study suggest that the introduction of appropriate life skills programs within institutes of higher education in India, could significantly improve the attitude of youngsters towards the misuse of illicit drugs. This may impact their behavior and reduce future misuse of illicit drugs.
Validation and cultural adaptation of the Brief Obsessive Compulsive Scale (BOCS) among Sri Lankan Sinhala speaking children and adolescents
Authors: Rupasinghe D. , Samaranayaka D. , Senevirathna M. F. S. P.
Published: June 2022

Background: Epidemiological studies reveal that over 50% of adults with obsessive compulsive disorder (OCD) report that their symptoms started during childhood or adolescence, with a mean age of onset around 9 years. Lack of diagnostic tools for screening of OCD among children and adolescents in their native language, adds to the burden of already limited child and adolescence mental health services (CAMHS) in Sri Lanka.
Methods: The Brief Obsessive Compulsive Scale (BOCS) was translated into Sinhala, and cultural and semantic adaptation was conducted. Criterion validity was measured for the symptom checklist and severity scale, by administration of the translated tool to a sample of children and adolescents – the cases consisted of 50 children and adolescents aged 8-18 years, diagnosed to have OCD, who attended the CAMHS at Lady Ridgeway Hospital, Sri Lanka. Age and sex matched controls consisting of 50 healthy children and adolescents were selected from the general population.
Results: Criterion validity scores were obtained via the receiver operator curve for the severity scale, with a cut off of 0.92, which had a sensitivity and specificity of 100% and 92% respectively. The reliability measured by Cronbach’s alpha were 0.78 and 0.94 for the symptom checklist and severity scale respectively.
Conclusions: The locally validated BOCS has a high criterion validity, with an excellent reliability for diagnosing OCD in children and adolescents in Sri Lanka.

Childhood aplastic anaemia with paroxysmal nocturnal haemoglobinuria clones: A retrospective single-centre study in South Africa
Authors: Hendricks Candice L. , Naidoo Ashen , Thejpal Rajendra , Rapiti Nadine , Neethling Beverley , Goga Yasmin , Buldeo Suvarna
Published: June 2022

Background: Paroxysmal nocturnal haemoglobinuria (PNH) clones in children are rare but commonly associated with aplastic anaemia (AA) and myelodysplasia.Objective: This study aimed to determine the prevalence of PNH clones in paediatric patients with idiopathic AA, identify differences in clinical and laboratory features and outcomes, and determine the impact of clone size on clinical presentation.Methods: Patients with confirmed idiopathic AA who were tested for PNH between September 2013 and January 2018 at the Inkosi Albert Luthuli Central Hospital, Durban, KwaZulu-Natal, South Africa, were included. PNH clones were detected in neutrophils and monocytes by flow cytometry using fluorescent aerolysin, CD24, CD66b and CD14.Results: Twenty-nine children with AA were identified and 11 were excluded. Ten patients (10/18, 55.6%) had PNH clones ranging from 0.11% to 24%. Compared to the PNH-negative group, these children were older (median: 10 years vs 4 years, p = 0.02) and had significantly lower total white cell counts (median 1.7 × 109/L vs 3.2 × 109/L; p = 0.04). There was no difference in median absolute neutrophil count or haemoglobin concentration. Four patients in each group received immunosuppressive therapy (IST). At six months, all four patients with PNH clones had responded, compared to one in the PNH-negative group.Conclusion: More than half of children with AA had a PNH clone. The size of the clone did not impact clinical severity; however, IST use may positively impact prognosis. We recommend early initiation of IST in patients with AA to avoid delays associated with human leukocyte antigen typing.

Published: June 2022

Background: The purpose of this study was to explore how D/deaf learners in the Eastern Cape Province of South Africa constructed their careers and what types of support were available for them to do so. The study found that among the support required, support for their linguistic development, and particularly sign language acquisition, was critical in home, school and community contexts.Objectives: The objective of this paper is to highlight the multiple linguistic exclusions faced by D/deaf learners in the Eastern Cape, which negatively impact their career construction.Method: Savickas theory of career construction framed this analytical-qualitative case study. The study was conducted in two out of four schools for the D/deaf in two districts of the Eastern Cape, South Africa.  Data was gathered via four participant groups viz. Deaf learners, their parents, teachers and officials of the Department of Basic Education, as well as through documents reviews.Results: The results indicated that multiple linguistic exclusions for these learners begin  early in their lives and continue into their school years and beyond. These experiences at home, school and in social contexts combined, impact negatively the process of career construction and its prospects.Conclusion:  The study concluded that linguistic exclusions are exposed by the study  are  created by a combination of systemic factors which impede the career construction of d/Deaf learners.  Implications and suggestions for advancing their linguistic inclusion are discussed.

Authors: Lefoka Moganki H. , Netangaheni Robert T.
Published: June 2022

Background: Substance use disorder has emerged as a key health and social challenge in South Africa (SA). It is projected that about 15% of South African youth, especially young women are prone to engage in drug use and the prospects of coming into contact with nyaope, a highly addictive drug, are higher. Nyaope is mainly smoked, but the prevalence of injecting it is increasing in most regions.Aim: This study aimed to explore and describe the perception of women, who use nyaope, about the factors contributing to nyaope smoking and transitioning to injecting nyaope amongst women in the City of Tshwane Municipality (CoT), Gauteng.Setting: The research was conducted within Community Oriented Substance Use Programme sites across the CoT Municipality.Methods: Qualitative research methods were utilised to explore and describe the perceptions of the participants on factors contributing to the use of nyaope amongst women residing in the CoT. Data were collected through face-to-face interviews and thematically analysed.Results: Intimate partner influence (IPI), peer pressure, being misled by friends, weight loss, lack of effective coping mechanisms and counteracting other drugs contributed to women smoking nyaope. Additionally, a need for an intense high, IPI, influence by the social network, curiosity and cost-effectiveness contributed to women transitioning from smoking to injecting nyaope.Conclusion: The study has established factors contributing to smoking and transition to injecting nyaope as viewed by women residing in the CoT.Contribution: This research affirms that women are influenced by different factors to use and transition to injecting Nyaope.
‘Not getting what you ask for’ from rapid appraisal surveys: A new model to assess Bible translation needs
Authors: Houston Tobias J.
Published: June 2022

The decision to initiate a Bible translation project in any community has profound implications. In logistical terms, Bible translation projects can be expensive and taxing on their donors, initiators and other stakeholders. However, they can also have positive transformative effects on the communities that benefit from the translation. Therefore, the decision to translate should be carefully considered. In many cases, a rapid appraisal survey is conducted to determine the remaining Bible translation needs in a given situation. This article assessed the validity of rapid appraisal surveys using the Yaawo context of Mozambique as a case study and cautions against their use when performed in isolation. A new model is proposed based on the object metaphor of a beaded necklace that, although it involves more time and resources, will result in a more appropriate response to the needs (or lack thereof) for Bible translation in each context. Supplementing the beaded necklace model for determining Bible translation needs, insights from narrative frame theory are highlighted as they were applied recently to the complex Yaawo context in Mozambique. These insights are presented to demonstrate that initiating a Bible translation project is not just a sociolinguistic decision but a contextual one as well.Contribution: The translation of the Bible is a complex process. This article demonstrates that narrative framing is a useful tool for managing the complexity around a new Bible translation project by offering a new model for stakeholders and initiators to assess and manage the context of a new Bible translation situation.

Published: June 2022

Muslim scholars have defined ethics as enduring traits and characteristics in the individual that cause actions appropriate to those traits to be issued spontaneously without the need for human thought and reflection. Islamic ethics state the rightness or wrongness of these attributes within the framework of Islamic concepts, while the concepts of Islamic work ethics deal with the functioning of the framework of Islamic concepts in the form of human work activities in various organisations. Furthermore, work ethics can be effective in the organisation when it can shape the culture of the organisation. Research shows that Islamic work ethics have a significant relationship with various individual, professional and organisational factors. The purpose of this study is to investigate the relationship between Islamic work ethics and organisational culture. The statistical population of this research consists of 1500 Muslim staff of 30 service organisations (financial, educational, medical and hotel organisations) in Moscow, Russia, in 2021, of which 306 people have been selected as statistical samples using Krejcie and Morgan’s sample size table. Data analyses were performed by statistical software, Statistical Package for the Social Sciences (SPSS). The results of this study confirm the significant and positive relationship between Islamic work ethics and organisational culture among the Muslim Russian staff (β = 0.53; T = −8.65).Contribution: This study examines the relationship between Islamic work ethics and organisational culture in Russia and has expanded the results of previous studies conducted in other contexts.

Ethical behaviour, in its simplest terms, means knowing and doing what is right. Nevertheless, the main difficulty is how to define the word ‘right’. For this purpose, various individuals, cultures and religions have thus far portrayed it in different ways. The present study reflected on the Islamic society, wherein ethical leadership has been one of the most effective factors in its continuation of life and success, with a vital role in its growth, development and progress. Accordingly, the relationship between ethical leadership and the voice of Muslim employees in Kuala Lumpur, Malaysia, in 2021, as the statistical population (n = 2500) was analysed. For this purpose, a standard questionnaire was used to collect the necessary data, whose validity was confirmed by the construct validity in the Linear Structural Relations (LISREL) software and its reliability was checked via the Cronbach’s alpha in the Statistical Package for the Social Sciences (SPSS) software. Besides, path analysis was utilised to test the research hypothesis. Confirmatory factor analysis was correspondingly implemented to examine the data. Ultimately, the study results revealed a significant positive relationship between ethical leadership and the voice of Malaysian Muslim employees (p = 0.80; t = 5.02).Contribution: Based on the literature review and the results of this study, ethical leadership can motivate Muslim citizens to participate in decision-making processes and even allows them to express their creative ideas in organisations and society.
Assessment of barriers that prevent the integration of UNHCR and church responses to migration: An ecclesiological perspective
Authors: Magezi Christopher
Published: June 2022

This article perceived the United Nations High Commissioner for Refugees (UNHCR) as a United Nations agency whose mandate is to safeguard refugees, forcibly displaced communities and stateless people. However, in discharging this mandate, the UNHCR involves many stakeholders, including churches. In focusing on the church, this article identified a number of barriers to the UNHCR-church integration in responding to the challenges faced by migrants, particularly refugees. In view of this background, this article aimed to provide a critical assessment of the barriers that prevent the integration of the UNHCR and church responses to migration, and consequently, offer recommendations from an ecclesiological perspective. As a literature-based study, this article reviewed literature on the proposed issue and discovered multiple barriers that hamper the UNHCR-church integration in responding to the challenges faced by migrants with a particular focus on refugees. Such barriers include legal, theological, financial, power inequality and the rotation of the UNHCR members. This article advanced recommendations to address the identified barriers; thus, enhance the UNHCR-church integration in responding to the challenges that refugees and other migrants are confronted with.Contribution: The contribution of the article lay in identifying and discussing the barriers that hamper the UNHCR-church integration in responding to migration challenges, and making the ecclesiological recommendations that ensued from that discussion.
Water baptism as church membership identity in Nigeria
Authors: Ademiluka Solomon O.
Published: June 2022

In the New Testament (NT), water baptism symbolises forgiveness of sins for the baptised, and their identification with Jesus Christ and the church as a body, but not the means of salvation. Most Nigerian churches involve baptism in certain practices, which apparently treat baptism as proof of salvation. This article examined such practices and assessed the extent to which they conform to the NT purpose of baptism. Employing the historical and descriptive methods, this research found that in the NT baptism was the means of public confession of Jesus as one’s Lord. Although several passages in the gospels and Acts give the impression that salvation is tied to baptism, there are many NT passages which make salvation absolutely God’s grace. This article discovered some church practices in Nigeria that suggest that water baptism is necessary for salvation. This attitude is seen in individual denominations making baptism their membership identity. Some other practices treat baptism as proof of salvation and holiness, which include denial of baptism and full membership to polygamists and making baptism a prerequisite for certain privileges. This article concluded that these practices contradict the NT purpose of baptism in that it was intended for identification with Christ and the universal church, not as membership identity of local church groups, or evidence of holiness.Contribution: This research is a contribution in New Testament theology. It argues that the adoption of water baptism as church membership identity in Nigeria, contradicts the original purpose of the sacrament.
Demonology, eschatology and vaccinology in African independent Pentecostalism
Authors: Kgatle Mookgo S.
Published: June 2022

Public discourses on the reliability of coronavirus disease 2019 (COVID-19) vaccines in dealing with the upsurge of virus cases and deaths are developing and ongoing in many different contexts, as countries around the world are doing their best to build high and lasting immunity. This article worked within the framework of Pentecostal faith and outlined the Pentecostal perspectives on COVID-19 vaccines. The article is a literature analysis on the eschatological view and the demonising of COVID-19 vaccines. In addition, the article analysed the social media utterances of Pentecostal pastors on COVID-19 vaccines. These utterances were obtained from different social media networks, including YouTube. Pentecostal faith has caused some independent Pentecostals in Africa to demonise COVID-19 vaccines and others to perceive them as signs of the end times. While these perceptions appeared as signs of faith in dealing with pandemics such as COVID-19, they have proven fruitless in some instances. Some Pentecostals in Africa have lost their lives due to their insistence on faith, instead of vaccinating against the virus and observing regulations and restrictions. This calls for scholars to revisit a Pentecostal faith in health issues by bringing the balance between works and faith.Contribution: This article is an interdisciplinary study on demonology, eschatology, and vaccinology within African Independent Pentecostalism. The article problematised the demonisation of vaccines and perception of vaccines as signs of end times. The article proposes a Pentecostal faith that balances people’s beliefs and the role of medicine in the provision of healing.

Developing strategies to control environmental challenges and various aspects of health consequences of waste management is one of the major programs in metropolitan management. The main purpose of this study is to examine the level of preparedness, having a contingency plan and the emergency response ability to waste management in disaster situations. A descriptive study was designed in two phases: in the first phase of the study, composition, quantity and characteristics of municipal solid waste in the disaster were estimated, and by using DotMapper software, temporary waste sites for disaster situations (map waste) were determined. In the second phase of the study, the preliminary hazard analysis (PHA) to identify the initial events and risk analysis in the municipal waste management system was considered. Results show that more than 50% of the generated waste in the disaster is allocated to construction waste resulting from the destruction and more than 30% to recyclable items (metals, glass, plastic), and a very small part of about 1% of biodegradable waste was determined. Twenty points were designated as temporary sites for municipal waste in a disaster situation. Results of risk analysis in the disaster were described that for three events containing lack of temporary waste storage sites, lack of identification and determination of hazardous waste production centres and lack of waste management training programme in emergency situations were in the red range. Developing the necessary strategies to control environmental challenges and various aspects of health outcomes in waste management is one of the basic programmes in metropolitan management.

Weathering the storm: Learning strategies that promote mathematical resilience
Authors: Khumalo Vuyisile L. , Van Staden Surette , Graham Marien A.
Published: June 2022

Most learner achievement studies tend to focus on identifying individual characteristics, ignoring the learning strategies that promote mathematical resilience. The focus of the study is on the assets embedded in an individual and their interplay with the environment. It is expected that resilience plays a deciding role in learners’ foreground with the potential to affect learner mathematics achievement in constrained environments positively. This study, framed within the socio-ecological perspective of resilience, explored how disadvantaged learners learn mathematics in a disadvantaged environment in the Further Education and Training band in South Africa. A total of nine (five boys and four girls) Grade 12 learners learning mathematics in disadvantaged environments from Johannesburg West and Johannesburg Central districts were purposively selected and one-on-one semi-structured interviews were conducted with them. This thematic report pays attention to the qualitative phase of a broader study that employed a sequential exploratory design that draws from the work of Vygotsky, Carroll and Skovsmose. The framework focuses on the dynamic interactions between learners and the connection between the home and the school. Accordingly, the findings revealed two interrelated themes, namely foreground and growth strategies. These themes make apparent the connection between the context and the interpretation of the context by an individual as translated into decisional processes. Implications for teachers are discussed.

Background: Founder mutation is a heritable genetic alteration observed with high frequency in a geographically and culturally isolated population where one or more ancestors becomes the forebearer of the altered gene. The current study reports two founder mutations in the BRCA1 gene in the Nepalese people.Methods: Germline BRCA testing in all surface epithelial ovarian cancers and the selected case of breast, prostate, and pancreatic cancers has been the standard practice from 2016 to 2021. One thousand one hundred thirtythree probands were screened for germline BRCA variants by next generation sequencing. The variants were classified as per the American Society of Medical Genetics and Genomics recommendations. Pathogenic (class V) and likely pathogenic (class IV) were considered clinically relevant and utilized for cascade screening.Results: Nepalese population made up a subcohort of 5.12% (58/1,133) of probands tested for germline BRCA1/2 variants. Twenty-seven of these 58 tested harbored pathogenic genetic alterations in BRCA1/2 genes, with 23 being BRCA1 mutant. Sixteen of 23 BRCA1 mutant cases shared one common pathogenic mutation c.2214_2215insT (p.Lys739Ter) (NM_007294.4). Additionally, a second highly recurrent mutation in BRCA1 gene c.5068A>T (p.Lys1690Ter) (NM_007294.4) was noted in six patients from this population.Conclusions: The overwhelming abundance of the above two variants in a geographically confined population confers these two genetic alterations a status of founder mutations amongst the people of Nepal. A more extensive population-based study to reaffirm these findings will help establish a dual site-specific germline testing similar to the “Multisite-3-assay” in Ashkenazi Jews as the primary screening tool, especially in a resource-constrained environment.
Existence, uniqueness, and approximation of a fictitious domain formulation for fluid-structure interactions
Authors: Boffi Daniele , Gastaldi Lucia
Published: June 2022

In this paper, we describe a computational model for the simulation of fluidstructure interaction problems based on a fictitious domain approach. We summarize the results presented over the last years when our research evolved from the finite element immersed boundary method (FE-IBM) to the actual finite element distributed Lagrange multiplier (FEDLM) method. We recall the well-posedness of our formulation at the continuous level in a simplified setting. We describe various time semi-discretizations that provide unconditionally stable schemes. Finally, we report the stability analysis for the finite element space discretization, where some improvements and generalizations of the previous results are obtained.
The regularity problem for degenerate elliptic operators in weighted spaces
Authors: Auscher Pascal , Chen Li , Martell José María , Prisuelos-Arribas Cruz
Published: June 2022

We study the solvability of the regularity problem for degenerate elliptic operators in the block case for data in weighted spaces. More precisely, let

L_w

be a degenerate elliptic operator with degeneracy given by a fixed weight

w\in A_2(dx)

in

\mathbb{R}^n

, and consider the associated block second order degenerate elliptic problem in the upper-half space

\mathbb{R}_+^{n+1}

. We obtain non-tangential bounds for the full gradient of the solution of the block case operator given by the Poisson semigroup in terms of the gradient of the boundary data. All this is done in the spaces

L^p(vdw)

, where

v

is a Muckenhoupt weight with respect to the underlying natural weighted space

(\mathbb{R}^n, wdx)

. We recover earlier results in the non-degenerate case (when

w\equiv 1

, and with or without weight

v

). Our strategy is also different and more direct thanks in particular to recent observations on change of angles in weighted square function estimates and non-tangential maximal functions. Our method gives as a consequence the (unweighted)

L^2(dx)

-solvability of the regularity problem for the block operator

\mathbb{L}_\alpha u(x,t) = -|x|^{\alpha} \mathrm{\operatorname{div}}_x \big(|x|^{-\alpha } \,A(x) \nabla_x u(x,t)\big)-\partial_{t}^2 u(x,t)

for any complex-valued uniformly elliptic matrix

A

and for all

-\varepsilon<\alpha<{2n}/(n+2)

, where

\varepsilon

depends just on the dimension and the ellipticity constants of

Phytochemical and Antibacterial Study of Ethanol and Ethyl acetate Extracts from Leaves of Alchornea Cordifolia Against Isolates from Infected Wounds
Authors: Mohammed Aisha , Ado Bashir K.
Published: June 2022

Alchornea cordifolia leaves have been reported to be used traditionally to treat wound infections. The leaves ofAlchornea cordifolia were extracted with ethanol which was partitioned with ethyl acetate to obtain the ethanolextract and ethyl acetate fraction respectively. The extracts were screened for basic phytocompounds and subjectedto antibacterial assay against bacterial isolates from infected wounds which include Pseudomonas aeruginosa,Staphylococcus aureus, Klebsiella spp, Enterobacter spp, Citrobacter spp, Escherichia coli, Proteus mirabilis andProteus vulgaris. Agar well diffusion method was used to determine the antibacterial activity of the extract andfraction. Phytochemical investigation revealed the presence of carbohydrates, cardiac glycosides, saponins,flavonoids, tannins and alkaloids. The zone of inhibition ranged between 1.0 - 32.2mm for the entiremicroorganisms. This variation in level of the activity among the extracts could be due to the difference in solubilityof the active ingredient in each solvent on one hand and to the constitutional or structural variability of the testedorganisms on the other hand. The results of the study showed that the ethyl acetate fraction of Alchornea cordifolialeaves possess high level of antibacterial activity against bacteria associated with wound infection. This givescredence to traditional medicine application of the plant for treating wound infections.

In this study, the production and characterization of bioethanol from rice and corn straws were investigated.The bioethanol was produced through dilute acid hydrolysis, fermentation and distillation; and the distillateswere purified by dehydration using zeolite 4A. The physicochemical and fuel properties of the bioethanoldistillates including pH, refractive index, specific gravity, flash point, octane rating and calorific or heatingvalue were evaluated. Further characterization of the biofuel was carried out using FTIR and GC-MS. Theresults indicated that octane number, calorific value, and specific gravity of the corn straw bioethanol obtainedwere significantly higher (p<0.05) compared to rice straw bioethanol. Meanwhile, no statistically significantdifference (p˃0.05) was observed in the flash point, refractive index, pH, pour and cloud points of thebioethanol produced from the two lignocellulosic substrates. Furthermore, the results reveal that pH, octanenumber, specific gravity and flash point are within the ASTM standards while refractive index, cloud and pourpoint were slightly outside the ASTM standard. This reveal potential of the feedstock as a source for Bioethanolproduction.
