Authors: Legesse Tesfaye Kebede
Published: April 2023

BACKGROUND፡ The current COVID-19 pandemic is forcing the world community to change how things should be done to avoid widespread transmission and containment of infection. Some countries are promoting “Work from Home” for disciplines like radiology” to prevent infection dissemination in hospital facilities. So the aim of this study is to introduce ‘work & teach and from home’ during the pandemic by establishing convenient virtual platforms for faculty members and students.METHODS: This implementation research introduced a model “teach and work from home’’ during COVID pandemic. It was evaluated using a cross-sectional design to assess the effect of attending each session on the exam score of residents during the 1st 2 months of the COVID-19 declaration in Ethiopia. Teaching and service activities that didn’t require physical presence were identified and replaced with virtual activities. Additional faculty teaching activity was also introduced to compensate for the reduced radiology caseload.RESULTS: Teach and work from home was introduced, and a total of 196 online teaching activities were conducted during the model’s two-month introduction. Online attendance of teaching activities was shown to have a positive relation with exam scores for all levels of trainees.CONCLUSION: It was able to introduce teach and work from home model in the department of radiology at Addis Ababa university and it was shown that residents’ retention of knowledge with the virtual platform was encouraging. It also brought a new experience in virtual teaching which is still practiced after the pandemic

Published: April 2023

BACKGROUND: Harlequin syndrome is a rare disorder caused by autonomic nervous system dysfunction. It manifests as asymmetric facial flashing and sweating with contralateral anhidrosis. It may be primary (idiopathic) with a benign course or can occur secondary to structural abnormalities or iatrogenic factors. To our knowledge, there has been no report of idiopathic Harlequin syndrome published from Ethiopia. We are reporting this case since it signifies the existence of idiopathic Harlequin syndrome in our setting and the need to properly diagnose this condition.CASE PRESENTATION: We are reporting a 29-year-old female from Addis Ababa, Ethiopia, who presented with a complaint of left hemifacial hyperhidrosis of 8 years which worsen after routine household activities and exercise. Physical examination revealed left hemifacial hyperhidrosis with right-side anhidrosis. She was diagnosed with idiopathic Harlequin syndrome after an appropriate investigation revealed a nonremarkable finding. Symptomatic treatment showed no significant improvement and the patient was also counseled on the disease entity.CONCLUSIONS: The patient described here signifies an idiopathic Harlequin syndrome in an Ethiopian woman. This case highlights the existence of idiopathic Harlequin syndrome within our setting and the need to properly diagnose this condition.

Published: April 2023

BACKGROUND፡ The study aimed to identify the achievement of stunting prevention based on the contribution of the Village Apparatus, Integrated Health Services Post and Early Childhood Education. Moreover, it determined the effect of the personnel factors of each agency on the achievement of stunting prevention.METHODS: A cross-sectional study was conducted on 175 respondents in Surakarta residences covering Klaten, Boyolali, Karanganyar, Surakarta, Sukoharjo, and Sragen districts from August to October 2021. The researcher conducted a line plot to describe the score of stunting prevention efforts through SINAR APD in planning, funding, implementation, and monitoring. Linear regression and One Way Anova were analyzed using SPSS to determine the effect of the personnel factors.RESULTS: Personnel factors had a significant role in the achievement of funding for Stunting Prevention. The data of stunting showed knowledge (F=3.3; P<0.05), attitudes towards authoritative parenting (F=5.6; P<0.05), and attitudes towards permissive parenting (F=6.1; P<0.05).Conclusions: The main problem was the lack of achievement in the funding aspect. The researcher recommended further research to increase knowledge on stunting for village apparatus, Integrated Health Services Post and Early Childhood Education. Understanding good parenting patterns can change mindsets and attitudes to avoid applying parenting methods that are too authoritarian or permissive.

This study assessed the socioeconomic determinants of the use of social media among agriculture undergraduates in North-west Nigeria. Three States were purposively selected out of 7, and 250 students were randomly selected from the States. Data were collected with the aid of a questionnaire. Percentages, means and multiple linear regression models were used to analyze the data. Results of the data analysis reveal that 76.4% of the students’ had a monthly income of ₦10,000-₦30,000; 55.2% spent 10-29 hours per week using the social media. Facebook (x̄=3.18) and WhatsApp (x̄=3.02) had the highest number of users. Age, marital status and monthly income were statistically significant (P≤0.05); while years of formal education and the access to internet were both significant. Age, marital status and years of formal education were the major determinants of social media usage among agricultural undergraduates. The Nigerian communication commission should enforce a downward review of data bundles and also push for a larger access to free Wi-Fi services.

Published: April 2023

It has become difficult to articulate the impacts, needs and challenges of digitalization of agriculture due to the extensive nature of publications relating  to the digitalization of the agricultural sector. This review evaluated the effect of digitalization of agriculture on improved food production and standard of  living, identified the training needs of extension staff and clientele for digitalization of agriculture, and highlighted the challenges of digitalization of  agriculture. From an initial search of 208 articles, only 87 articles met the inclusion criteria using the PRISMA guidelines. Most articles were published  between 2016 and 2020; more studies were carried out in the South Western region of the country. Digitalization of agriculture has reduced the role of  middlemen, provided opportunities for farmers to expand their markets, and improved the linkage between extension and research centers, and  productivity and livelihood of small-scale farmers. Training needs for effective digitalization of agriculture were in skills, use of relevant digital services,  digital privacy and security risks. Challenges of digitalization of agriculture were lack of technical skill, poor infrastructure and high cost of purchase and  maintenance. The government should focus on initiating agricultural technology transfer programs and provide the necessary rural infrastructure to  support the sector's digitalisation.

Published: April 2023

The study examined the causes of cassava post-harvest losses among farmers in Imo State, Nigeria. A structured questionnaire was used to obtain data  from 120 rural farmers using multistage, random and purposive sampling techniques. Data were analysed using percentage, mean and standard  deviation. Findings from the study reveal that farmers frequently used mobile phone calls/SMS as their sources of information on cassava postharvest  losses (x̄ =3.01) followed by the use of radio( x̄=2.5) The findings also revealed that farmers experienced different forms of post-harvest cassava losses at  one point or the other. Physical loss was experienced by 95.64% of the respondent, economic loss (93.8%) and monetary loss (97.7%).The causes of  cassava post-harvest losses included lack of finance ( x̄=3.56) poor storage (x̄ =3.46) pest and disease infection (x̄ =3.46) inappropriate harvesting time (x̄ =3.40) among others. Most of the causes of cassava post-harvest losses identified in the study area are serious. Cassava farmers should be granted  credit facilities and been courage to form cooperatives to help raise the funds and get facilities needed to reduce post-harvest losses.

Published: April 2023

Background: Cyberbullying is typically defined as aggression that is intentionally and repeatedly carried out in an electronic context against a person  who cannot easily defend himself or herself. This study compared the prevalence and determinants of cyberbullying perpetration using the theory of  planned behaviour among in-school adolescents in rural and urban secondary schools in Osun State, Nigeria.

Methods: A comparative cross-sectional study design was employed. Using a multistage sampling technique, a total of 722 and 711 respondents were  recruited respectively across rural and urban secondary schools in Osun State. Data collection was by facilitated self-administered questionnaire while  data analysis was with IBM SPSS version 20. Determinants of cyberbullying perpetration were assessed using binary logistic regression. A p-value of <  0.05 was considered statistically significant.

Results: The preceeding three-month prevalence of cyberbullying perpetration was significantly higher in urban 220 (30.9%) than rural secondary schools 165 (22.9%), (p = 0.001). In terms of theory of planned behaviour, predictors of cyberbullying perpetration were similar in both locations:  positive/favourable attitude towards cyberbullying perpetration [rural—OR = 1.645, 95%CI = 1.050-2.577, p = 0.030; urban—OR = 1.681, 95%CI =  1.107-2.552, p=0.015], having a high intention to perpetrate cyberbullying [rural—OR = 2.101, 95%CI = 1.336-3.305, p = 0.001; urban—OR = 1.819, 95%CI = 1.184-2.796, p = 0.006].

Conclusion: These findings indicate that engaging the adolescents in behavioural change communication interventions will foster negative attitude  towards cyberbullying perpetration and promote positive coping mechanisms different from retaliation.

Background: Dust exposure in sawmills predisposes workers to respiratory health problems with characteristic respiratory symptoms. This study  assessed the prevalence and the factors associated with respiratory symptoms among sawmill workers in Sokoto state, North-West Nigeria.

Methods: This was a cross-sectional study conducted in Sokoto State, Nigeria. A total of 360 respondents were recruited using a two-stage sampling  technique. Data were collected using a pretested interviewer-administered questionnaire and analysed using IBM® SPSS version 23. Categorical data  were presented using frequencies and percentages, while the Chi-square test was used to test for association between respiratory symptoms and socio-  demographic/work variables. Binary logistic regression was used to assess predictors of respiratory symptoms. The level of significance was set at  p<0.05.

Results: The respondents' age ranged from 19 to 73 years, with a mean of 34.12 ± 10.2 years. A quarter 92 (25.6 %) of the workers smoked cigarettes.  None of the workers had training on safety practices, and only a few 84 (23.3%) used personnel protective equipment (PPE). The most prevalent  respiratory symptom was morning cough 164 (45.6%), followed by cough on exertion 143 (39.7%). Cigarette smoking (aOR = 3.96, 95%CI = 2.03-7.73, p  <0.001) and loading of plank (aOR = 2.16, 95%CI = 1.21-3.85, p = 0.01) were the only predictors of respiratory symptoms.

Conclusion: Periodic safety  training and promotion of PPE use through education and advocacy and smoking cessation programs among sawmill workers will go a long way in  reducing the burden of respiratory problems among them.

Introduction: Western Learned Magic as an Entangled Tradition
Authors: Otto Bernd-Christian
Published: April 2023

The introduction to this special issue outlines the concept of Western learned magic and suggests to analyse it as an entangled tradition, thus calling for an interdisciplinary, transcultural and transreligious perspective on its history. A working heuristic of seven different types of entanglement in the history of Western learned magic is proposed, whereas special emphasis is placed on processes of ritual hybridisation. Entangled rituals are one of the most unique characteristics of Western learned magic and often mirror millenia-long processes of textual-ritual transmission across numerous cultural and religious boundaries. Inspired by this working heuristic of different types of entanglement in the history of Western learned magic, the introduction summarises the six contributions to this special issue. These contributions represent the fruits of a workshop on *Western learned magic as an entangled tradition* that was held at the Center for Religious Studies (CERES) at the University of Bochum on September 14–15, 2019.

Published: April 2023

Nagpur municipal corporation (NMC) is the best waste disposal company. Nagpur municipal corporation (NMC) collects everything from household waste and stores all the garbage in different landfills. But these landfills pose a major problem for storing this waste safely as it catches fire very quickly. These toxic gases such as dioxins, furans, mercury and polychlorinated biphenyls are then released into the atmosphere and pollute the air with an unpleasant smell. The design we propose is based on a fire alarm and a landfill fire extinguisher. When garbage is gathered for the dump, our project flashes a warning. Smoke alarm, temperature sensor, and Wi-Fi module powered by batteries Our sensor checks for smoke and temperature; if either is present, an alarm will be shown on the signal from the Wi-Fi module fi that is linked to a junkyard. An IoT-based fire extinguishing system is proposed for dump yards, providing an efficient and unique approach to prevent and extinguish fire outbreaks using sensors, actuators, and a cloud-based monitoring system. This research presents an innovative IoT-based fire extinguishing system for dump yards that incorporates sensor nodes to detect fire, actuator nodes to discharge extinguishing agents, and a cloud-based monitoring system for remote monitoring and management. The proposed system provides an efficient and effective approach to prevent and control fire outbreaks in dump yards, ensuring safety and environmental protection. This paper presents a novel IoT-based fire extinguishing system for dump yards, which utilizes sensor nodes to detect fire outbreaks and actuator nodes to deploy extinguishing agents. The system also includes a cloud-based monitoring and control system that enables remote monitoring and management of the system. The proposed system aims to provide an efficient and reliable approach to prevent and extinguish fire outbreaks in dump yards.

Published: April 2023

A configuração do mundo em que vivemos é o resultado histórico de uma evolução de características societais que moldaram valores, mentalidades e convicções, que outorgaram no desporto um modo de vida, e uma dinâmica que envolve diferentes partes interessadas. O objetivo desta investigação é aferir da dinâmica dos eventos desportivos do ponto de vista policial, por forma a disponibilizar aos gestores de infraestruturas desportivas, nomeadamente, pavilhões desportivos, ferramentas e elementos que possibilitem tomadas de decisão conjuntas e eficientes para manter a segurança e proteção da miríade de intervenientes no processo. O escrutínio apurado desta envolvente levanta questões, reflete os interesses, os valores, e as necessidades dos intervenientes. Estes elementos, descritos por intermédio duma revisão da literatura científica e legal, possibilita o conhecimento dos processos de intervenção policial e as potenciais melhorias a desenvolverem. As infraestruturas de desporto, pavilhões desportivos, carecem de uma intervenção securitária em termos de ajustamento das mesmas às necessidades de segurança, em função das sugestões e planos delineados pela Polícia de Segurança Pública. A convergência literária aponta para que o trabalho silencioso das forças de segurança é inestimável e fundamental na prossecução dos eventos desportivos de sucesso securitário e, consequentemente, desportivo. A ausência de problemas de segurança é um primeiro pilar desse sucesso.

Authors: Gomes Marcelle Karyelle Montalvão , Neto Aníbal Monteiro de Magalhães , Gonçalves Luis Carlos Oliveira
Published: April 2023

As atividades físicas de aventura na natureza, já há muito tempo inseridos na grade curricular do curso de educação física, propiciam o compartilhamento do conhecimento entre os sujeitos cognoscente e cognoscível, formando valores e modulando atitudes e condutas para o bem da sociedade. A presente revisão narrativa da literatura objetivou a apresentação da corrida de orientação como ferramenta de desenvolvimento holístico para indivíduos de diferentes idades, classes sociais, gêneros e estados de saúde.Em se considerando o Professor como sujeito cognoscente, este tem uma importante e atual ferramenta como objeto cognoscível prático, ou seja, a conduta ou comportamento motor que gera alterações no objeto cognoscível formal (o aluno) que é a corrida de orientação. Toda a prática física pode gerar adaptações com relação direta ao tipo, volume e intensidade do estímulo. Quando um estímulo é considerado débil ele apenas excita ou aquece o organismo, já quando o estímulo é adequado gera adaptações fisiológicas e cognitivas positivas para o desenvolvimento dos sistemas. Já quando o estímulo é excessivo para a idade, nível de treinamento ou estado de saúde, este pode gerar adaptações negativas como o overtraining. Desta forma, a corrida de orientação se apresenta como alternativa adequada a ser implantada em escolas e centros esportivos, visando a promoção da saúde física, mental, social, ambiental e proprioceptiva dos indivíduos em formação.

PHYSICAL MODEL OF W AND Ti COMPOUND DURING HOT VACUUM ROLLING IN THE SOLID PHASE
Authors: Andrieieva O.L. , Tkachenko V.I.
Published: April 2023

The paper considers alternative methods for protecting metal surfaces from corrosion-erosion destruction (CED), based on galvanization or on the use of an oxide film. Their advantages and disadvantages are noted. For the manufacture of CED-resistant tungsten targets, which are used in the subcritical assembly created at the NSC KIPT, it is proposed to use the method of vacuum rolling of W and Ti. A layer of Ti serves as a protective coating. To describe the process of combining these metals, a model description is proposed, which is based on the use of the Rayleigh-Taylor dissipative instability theory (DRTI). An estimate of the values of the parameters of a binary metal system subjected to DRTI is given. The obtained characteristic bonding time of dissimilar metals corresponds to that observed in experiments.

The influence of the technological parameters of the SHS process (temperature, holding time and alloying of B, Cr, Ti) on the corrosion resistance of brass with a surface alite layer, which effectively resists β-radiation, was studied. The research was carried out in 30% aqueous solutions of HNO3, HCl, H2SO4. Aluminized coatings doped with silicon, which are obtained under optimal parameters, have 1.7-2.1 times higher corrosion resistance than
doped B and Ti. Alloyed coatings have phases CuSi, CuAl, CuAl2, CuTi, Ti2Cu3, CuCr, Cu3Al, Cu2Al, Al3Si, and α-phase doped with Cr, Al, Si, B, Ti. When tested in a 30% aqueous solution of nitric acid, the coating doped with titanium and silicon shows a weight loss of 32 and 37 g/m2, respectively.

Published: April 2023

For the isotropic beam elements of the technological equipment (BETE), which are used in the production of carbon-carbon composite materials (CCCM) in direct heating furnaces, the analytical solution of the temperature stress-strain state, taking into account the stiffness of the spring of the current collector, was obtained for the first time in the work. Formulas for calculating the critical diameters of loss of compressive strength are given. Using the example of graphite and molybdenum rods, it was established in the work that the decisive factor of the load-bearing capacity is the loss of stability of the elements under consideration.

Investigations on gas-phase densification of CCFs, obtained on iron, using the radially driven pyrolysis zone and, at the same time, the temperature rise in the pyrolysis zone with the speed of the 1.25 °С/h, were carried out. CCFs, bonded with pyrocarbon (CCFBPyC), not refined from iron, without defects, with density and PyC content corresponding to the material: graphite bonded with pyrocarbon (GBPyC), which include 90 wt.% of PyC (GBPyC90), were obtained. The necessity of applying the special technological methods in the process of gas-phase densification of CCFs, was confirmed.
Ocular Manifestations and Tear or Conjunctival Swab PCR Positivity For SARS-CoV-2 In Patients With COVID-19: A Systematic Review and Meta-Analysis
Authors: Bhattacharyya Anusuya
Published: April 2023

Background: Respiratory viruses have a tendency for ocular-tropism and SARS-CoV-2 is one of them. In this context, we have undertaken this systematic literature-review and metaanalysis for systemic evaluation of ocular symptoms of COVID-19.

Material and Method: We have screened 14 literature databases applying key-words “Ocular”, “Ophthalmic”, “Conjunctiva”, “Cornea”, “Retina”, “Sclera”, “Uvea”, “2019-nCov”, “2019 novel corona virus”, “COVID-19”, “corona virus disease-2019”. Studies published till 26th April 2020 were included. Studies conducted in COVID-19 population and reporting ocular ma infestations were included. Case reports, series, observational studies were included in the systematic review part, while only observational studies were included in the metaanalysis part. Pooled proportions were evaluated and reported along with 95% confidence interval. Heterogeneity was evaluated using I2 statistics and random or fixed-effect model was selected to evaluate the pooled proportions based upon presence of extent of heterogeneity.

Result: A total of 14 studies (total 2259 patients) were included in our systematic-review and metaanalysis which reported occurrence of ocular symptoms in COVID-19. In our study, prevalence of conjunctivitis/red eye in COVID-19 was 2.8% (95% CI 1.3% to 4.2%, I2=72.41%). Conjunctivitis/red eye was the first symptom of COVID-19 in 1.08% of patients (95% CI 0.37% to 2.44%, I2=0%). Tear sample PCR positivity rate in COVID-19 was 2.6% (1.3% to 4.5%, I2=47%). However, among COVID-19 patients with conjunctivitis/red eye, the PCR positivity rate in tear sample was 20.6% (6/29 cases). Again, among patients who were positive for the virus in tear sample by PCR, the proportion of conjunctivitis/red eye was 33.3% (4/12 cases). We also evaluated the association between occurrence of ocular manifestations and disease severity (mild and moderate vs. severe and critical). The odds was 0.28 (95% CI 0.12-0.67, I2=0%). This highlights that the mild to moderate severity disease had significantly lower occurrence of the ocular symptoms compared to the severe and critical group. However, we couldn’t find any association between tear sample PCR positivity and disease severity [odds ratio 0.46 (95% CI 0.06-3.45, I2=0%)].

Conclusion: In patients with COVID-19, 2.8% of patients show ocular manifestation. However, among patients with ocular manifestation, only 20.6% cases showed tear/conjunctival swab RT-PCR positivity. So, ocular symptoms may warrant a COVID-19 screening test during thie epidemic of COVID-19.

Las Reservas de Biosfera son considerados espacios de aprendizaje para el desarrollo sostenible, en ese sentido se planteó como objetivo medir el desarrollo sostenible en la Reserva de Biósfera Oxapampa-Asháninka-Yánesha durante su primer quinquenio de reconocimiento por la UNESCO; para ello. se ha definido como unidad de análisis cinco distritos integrados en el área de la reserva de biósfera (Chontabamba, Huancabamba, Oxapampa, Pozuzo y Villa Rica). A partir de 111 indicadores planteados por la ONU y los ODS, se definieron 39 indicadores estratégicos, los que fueron estandarizados mediante Z-score y posterior agrupamiento de datos por la técnica de análisis de los componentes principales (ACP) para generar 12 nuevos indicadores, a los que se asignaron nuevas etiquetas, el Z-score del nuevo indicador se transforma con el método percentil normal estándar con valor teórico entre 0 y 100. Para obtener los subíndices (social, económico, ambiental y político institucional) anuales, se aplicó la media simple; y con el promedio equiproporcional de dichos subíndices se obtiene el Índice de Desarrollo Sostenible cuadrimensional (IDS4). Se concluye que el estado del desarrollo sostenible, en los cinco distritos de la Reserva de Biósfera Oxapampa-Asháninka-Yánesha, está entre inestable y estable; y el análisis global gráfico indica un incremento del IDS4 en el primer quinquenio de creación.
