Published: March 2023

In mobile learning environment, context-aware systems refer to applications that employs contextual information to provide appropriate services to the leaners or other applications to perform a specific task. An important challenge in such applications is context modeling, using ontologies to model context information and to reason about context at a semantic level has attracted a lot of interest in the research community. Semantic Web technologies have been applied in recent years with different purposes in education. But, their applications for generating useful personalized mobile assessment resources have not been researched enough so far.In this paper, we introduce a context-aware approach that makes use of Semantic Web technologies to support personalized assessment in mobile environments. We propose a Service-based framework for bringing assessment techniques to mobile environment. We provide a formal description for our mobile assessment framework and detail the functionalities of its various layers. We have carried out also an experiment with computer science university students to evaluate our mobile assessment framework.

Published: March 2023

Self-care and self-orchestration are focal points for transformations in health care and well-being in the Netherlands. Citizens should live healthily, be active every day and manage their own health. In this context, we explore how persuasive information technology may support older people in developing and maintaining healthy behavior. In two cases (in the Dutch cities Wijchen and Arnhem) we designed concepts of services in co-creation with professionals and citizens. These concepts were based on persuasive guidelines and positively tested with professionals and citizens. In this paper, we present these concepts and critically examine them in relation to existing literature on persuasive technology and personal informatics. We argue for backing persuasive interface with genuine support for user needs and for increasing the actionability of personal informatics solutions. The presented solutions also highlight how self-, family-, and professional care can be connected in the design of health support systems.

Inkludering og mangfold er idealer på tvers av de organiserte arenaene for fysisk aktivitet i oppveksten, som barnehage, skole og organisert idrett. Samtidig viser forskning at ekskludering og marginalisering av forskjellige grupper av barn og unge er et tilbakevendende problem. Gjennom 19 kapitler skrevet av forskere fra ulike samfunnsvitenskapelige felt og disipliner, undersøker Bevegelsesfellesskap i oppveksten gjenstridige utfordringer, spenninger og sammenhenger på tvers av barn og unges bevegelsesarenaer.  
Bevegelsesfellesskap i oppveksten tilbyr en bred vifte av teorier, metoder, kritiske perspektiver og refleksjoner som åpner opp for nye forståelser av inkludering og mangfold i barn og unges organiserte fysiske aktiviteter. Kapitlene drøfter problemstillinger knyttet til utdanningsløp og idrett, men også høyere utdannings rolle i å utdanne fremtidige pedagoger og trenere. Til sammen utgjør boken et unikt bidrag til å tenke helhetlig og nyansert rundt politiske og praktiske løsninger. 
Boken vil være en viktig ressurs for lærere i barnehage og skole, ledere, trenere og andre profesjonsgrupper med interesse for å skape inkluderende bevegelsesfellesskap for barn og unge. Samtidig vil boken være en stimulerende kilde for studenter og forskere på jakt etter nye perspektiver på inkludering og mangfold.

Authors: Schier da Cruz Aristides , De Siqueira Barbosa Gabriela , Loureiro Rebouças Rebeca
Published: March 2023

Introdução: Proctocolite alégica (PCA) é uma condição transitória benigna, com início nos primeiros 6 meses de vida. Objetivo: avaliar os potenciais fatores de risco para ocorrência de proctocolite alérgica em lactentes encaminhados com suspeita diagnóstica de alergia à proteína do leite de vaca (PLV), a duração do sintoma e ocorrência de recidiva. Método: estudo retrospectivo com avaliação dos prontuários de lactentes com menos de dois anos de vida com suspeita diagnóstica de PCA por PLV. Resultados: dos 193 lactentes estudados a mediana de idade de início da colite foi 40 dias (IIQ 20–75 dias). A duração mediana do sintoma foi 18 dias (IIQ 6–50 dias). Recidiva da colite ocorreu em 47 pacientes (24%). Conclusões: a evolução da PCA é transitória e benigna, independentemente de sua duração. Recidivas não são ameaçadoras. Muitos casos são idiopáticos. O principal fator de risco para duração prolongada (>30 dias) é o aleitamento materno, e os fatores associados a duração curta são ingestão de PLV, prematuridade, antibióticos e infecções. Não é justificável promover o desmame ou contraindicar antibióticos ou vacinas.
PALAVRAS-CHAVE: Lactente. Colite. Proctocolite. Alergia à proteína do leite de vaca.

Published: March 2023

INTRODUCTION: Brain metastases are usually due to lung carcinoma, breast cancer and melanoma. The search to hospitals for neurological symptoms without prior knowledge of primary cancer is frequent. OBJECTIVES: Analyze the epidemiological profile of patients with brain metastases at Hospital do Rocio. METHODOLOGY: This is a cross-sectional study, with data collection from patients with brain metastases from the neurosurgery service of Hospital do Rocio, between 2010 and 2020. RESULTS: The sample consisted of 114 patients and the main primary sites were lung (39 %), non-determined site (25%) and melanoma (15%). Most (61%) were unaware of the primary cancer. The most affected site was the frontal lobe (32%), on the right side (41%), and most lesions were single (68%). CONCLUSION: The epidemiological analysis corroborated most of the findings in the literature, with the primary pulmonary site and the discovery of metastasis before the primary cancer being the majority of cases.
RELEVÂNCIA DO DIAGNÓSTICO GENÉTICO NA IDENTIFICAÇÃO DE VARIANTES GENÉTICAS RARAS EM DUAS FAMÍLIAS BRASILEIRAS COM SÍNDROME DE ALPORT: RELATO DE CASO
Authors: Kertscher Isadora , Arissa Takii Fernada , Fontes Noguchi Juliana , Raskin Salmo , Pereira Ferrari Lilian , Mikami Liya Regina
Published: March 2023

INTRODUÇÃO: A Síndrome de Alport é uma doença renal hereditária que se manifesta principalmente na infância com quadros de proteinúria e/ou hematúria intermitentes, podendo ser transmitida como herança ligada ao cromossomo X ou autossômica. É causada por variantes patogênicas nos genes COL4A3, COL4A4 e COL4A5 que codificam o colágeno IV, resultando em anormalidades estruturais na membrana basal do glomérulo, cóclea e olho, levando à clínica de risco de insuficiência renal, perda auditiva neurossensorial e anormalidades oculares. OBJETIVO: Relatar duas famílias com diagnóstico molecular de Síndrome de Alport, portadoras de variantes extremamente raras. METODOLOGIA: Análise retrospectiva de prontuários de duas famílias com diagnóstico molecular confirmado de Síndrome de Alport, autorizada pelo TCLE e aprovada pelo CEP. Com os dados obtidos foi realizado um comparativo com a literatura estudada pelas plataformas Scielo e PubMed. RESULTADOS: Na família A identificou-se uma deleção significativa do exon 37 no gene COL4A5 em dois pacientes que apresentavam hematúria e problemas renais brandos com um padrão de herança recessiva ligada ao X, pois só os homens são afetados. A família B apresentou a variante genética R373X na porção terminal do exon 19 do gene COL4A5 envolvendo uma substituição de base CpG->TpG, em um ponto quente mutacional (hotspot). Isso gerou uma heterogeneidade clínica, com comprometimento renal em ambos os sexos e audição comprometida apenas nos homens afetados, sendo observado um padrão de herança dominante ligada ao X, pois tanto os homens quanto as mulheres heterozigotas são afetados. CONCLUSÃO: Ambas as alterações genéticas identificadas são pouco descritas, ou nunca descritas, na literatura mundial e parecem estar relacionadas à variabilidade fenotípica apresentada pelos indivíduos afetados, portanto, este trabalho demonstra a importância de se confirmar por exames genéticos específicos a hipótese diagnóstica para uma doença de etiologia genética já que isso também auxilia no diagnóstico de outros casos familiares da síndrome.
“Game Terakoya class 1” walkthrough: Directing students’ post-game discussions, academic work and participatory work through goals, curriculum, materials and interactions
Authors: deHaan Jonathan
Published: March 2023

I designed a curriculum called the “Game Terakoya” (named for the Japanese Edo Period private schools that taught reading and writing) that connects games with language and literacy work. This paper is a walkthrough of my first concerted attempt to implement my combination of games and the pedagogy of multiliteracies in a typical class setting. I describe my mediation work, namely, setting specific goals, developing a curriculum and sequence of activities that targeted those goals, developing a grading rubric based on those goals, and developing materials and project work and being deliberate about my interactions with students around academic work and participatory project work. The class and I were successful in many ways, one of the most notable being most groups’ clear connections of gameplay to game discussions to intellectual work to participatory work. The class and I stumbled in some ways as well, such as one large group failing to collaborate and complete project work, and many students not providing enough reasons and details in their L2 project work worksheets. I suggest implications for other teachers’ classes and outline my numerous next steps to refine my continued explorations of games and multiliteracies pedagogy with my curriculum, materials and interactions with students.

Authors:   Hawler Medical University/ College of Medicine, Albarzinji Niaz Jawad
Published: March 2023

Background and objectives: Anti-Tumor necrosis factor agents are among the most effective therapies for Rheumatoid Arthritis, however, their optimal use is yet to be determined.In this 5 year open-labeled study attempted remission induction using standard therapy with infliximab in patients with poor response to ordinary disease modifying anti-Rheumatic drugs. Methods: Patients responding inadequately to methotrexate and at least one other disease-modi- fying anti-rheumatic drug were enrolled into a 24-week, controlled study with infliximab plus methotrexate or placebo plus methotrexate and some were enrolled in a subsequent open-label extension. The efficacy were evaluated by measuring the disease activity by using DAS-28(disease activity score in 28 points) and functional evaluation by using the health assessment questioner (HAQ). Results: Among 250 patients in the original trial, 220 received at least one dose of infliximab and were evaluated. At the time of analysis 160/ 220 (72.7%) patients had remained in the study and received treatment for a mean of 4.5 years. Withdrawals were for lack of efficacy (24%), adverse events (36%), and other reasons (50%). In 160 patients who completed 5 years treatment efficacy achieved in 6 months was maintained at 5 years. 45% achieved clinical remission (DAS28<2.6), and 27% had no physical function abnormalities (HAQ=0). Results were similar for 160 patients who received treatment for 3-5 years. Conclusions: In patients with persistently active Rheumatoid Arthritis despite Methotraxate therapy, repeated doses of infliximab in combination with methotraxate provided clinical remissions with functional and quality of life benefits were sustained.

Tribunales ambientales chilenos y regímenes especiales de responsabilidad por daño ambiental
Authors: Harris Moya Pedro
Published: March 2023

La reciente jurisprudencia chilena ha calificado a la responsabilidad ambiental
en función de la reparación material del daño, descartando una indemnización
de perjuicios. Aunque esta interpretación tenga por finalidad favorecer
restablecimiento del ambiente, otorgando facultades a los Tribunales
Ambientales en ámbitos diversos, diferentes limitaciones sustanciales y
procesales dificultan su concreción. Estos límites pueden superarse en base a
una lectura alternativa, que distinga una multiplicidad de responsabilidades
frente al daño ambiental y una unidad en su reparación, impuesta cualquiera sea
la ley aplicable.
Cambio de modelo en la transición energética: ¿otro tren que pasará?”
Authors: Galera Rodrigo Susana
Published: March 2023

Este trabajo refiere la estrategia de Transición Energética que recientemente se ha incorporado en España. Dicha estrategia persigue dos objetivos esenciales, descarbonización y cambio de modelo energético, que aquí se consideran separadamente. Desde ese planteamiento, se analizan los recientes cambios normativos del sector energético en España. A día de hoy, se concluye, el desarrollo de estos dos elementos conoce un importante desequilibrio: mientras el proceso de descarbonización camina ya a buen ritmo, el proceso de cambio de modelo energético espera aún ulteriores cambios normativos para despegar.
El principio de no causar un perjuicio significativo al medio ambiente (DNSH) como mecanismo de evaluación ambiental de las actuaciones del Plan de Recuperación, Transformación y Resiliencia: a propósito de la Orden HFP/1030/2021, del 29 de septiembre por la que se configura el sistema de gestión del Plan de Recuperación, Transformación y Resiliencia
Authors: Vicente Dávila Fernando
Published: March 2023

El Ministerio de Hacienda y Función Pública ha publicado recientemente la Orden HFP/1030/2021 que configura y desarrolla el sistema de gestión del Plan de Recuperación, Transformación y Resiliencia, en el que el principio de no causar un perjuicio significativo al medio ambiente (conocido como «DNSH»), se establece como uno de sus criterios específicos y por lo tanto de obligatoria consideración, en la ejecución de todas las actuaciones para todo el sector público y los perceptores de fondos. La evaluación de este nuevo principio ambiental se realiza en este sistema de gestión con un «test de daños ambientales» y una lista de verificación de «análisis de riesgo sobre impactos medioambientales no deseados», que los órganos responsables y gestores deberán cumplimentar para comprobar su aplicación en los procedimientos.

Sin embargo, bajo la simplicidad y sencillez de estos trámites formales destinados a facilitar la coordinación y el seguimiento, subyacen importantes implicaciones prácticas en términos de carga burocrática, complejidad técnica, disponibilidad de recursos específicos adecuados y la necesidad de generar certidumbre a los sujetos implicados. Así, advertimos que pueden surgir dificultades en el abordaje de esta tarea, sobre todo si tenemos en cuenta que se va a requerir un conocimiento técnico y especializado en materia ambiental que de momento no existe en muchas administraciones.

Published: March 2023

Cardiovascular disesaes are the leading cause of morbidity and mortality among diabetic patients. This study was a 12-months retrospective cross sectional audit of case folders of adult (>18 years) type 2 diabetic patients, who attended clinic at two (2) referral hospitals in North-East Nigeria, between June 2017 and May 2018. Patients’ data including socio-demographic characteristics, cardiovascular risk factors, medication history and clinical characteristics were retrieved. The data were presented as proportions and percentages in tables and pie chart formats. The analysis was done using statistical package for social sciences (SPSS) version 21.0. Of the 807 case folders that were reviewed, 64.5% were female patients, with majority (61.3%) below 50 yearsof age and 90.2% were married. Over 50% had secondary/primary education and most (57.9%) were unskilled labourers. About one-third (34.6%) were engaged in moderate to regular physical activities. The prevalence of hypertension, dyslipidaemia and obesity was 84.8%, 5.1% and 47.1% respectively. More than three quarters of the patients (87%) were on multiple oralantidiabetic agents and metformin was the most prescribed medication (93.8%). The antihypertensive agents with the highest prescription rate was lisinopril (57.9%), while 50.9%, 6.5%, and 2.7% received low dose acetylsalicylic acid, lipid lowering agents and pregabalin respectively. Hypertension was the most prevalent cardiovascular risk factor in the study population, followed by overweight/obesity. The prescription rate of metformin and Lisinopril is commendable, but there is need to increase the use of statins and pregabalin in the study settings.
GREEN SYNTHESIS, SPECTROSCOPIC ANALYSIS AND STABILISATION ENERGY OF IRON OXIDE NANOPARTICLES FROM AQUEOUS Ziziphus LEAF EXTRACT
Authors: KARU ELISHA , MAGAJI BUHARI , MOHAMMED BELLO ABDULLAHI
Published: March 2023

Ziziphus mauritiana (ZM) leaf extract was used to synthesize FeO nanoparticles (NPs) and characterised by UV-visible, FTIR, XRD, and SEM. From this study the phytochemical constituents present in the aqueous Ziziphus extract were identified to include phenols, saponins, flavonoids and tannins which both serve as reducing, capping and stabilising agents. The presence of these phytochemicals was confirmed from laboratory tests and infrared spectroscopy. A wavelength of 400 nm was found to correspond to the surface plasmon resonance and used to determine the stabilisation energy of the FeO NPs and found to be 299 kJ/mol. More so, a broad peak was observed at 3426 cm-1 for the leave extract and 3386 cm-1 for the FeO NPs corresponding to O-H stretching vibration probably from alcohols, flavonoids, and phenols. A significant IR peak observed at 536 cm-1 in the FeO NPs spectrum but absent from that of the plant extract, was assigned to Fe-O stretching vibration and serves as a strong evidence for the formation of the nanoparticles. The XRD analysis revealed facecentred cubic morphology with an average crystal size of 36.3 nm calculated by Debye – Scherrer equation and the SEM analysis showed the nanoparticles to be spherical in shape.The synthesized NPs were found to possess significant antimicrobial activity against S. typhi (18 µg/L), E. coli (15 µg/L) S. aureus (16 µg/L0 and S. pneumonia (16 µg/L) by welldiffusion method. The inhibiting activity of the synthesized NPs increased with increase in concentration of the nanoparticles.

Rain is inherently acidic, human anthropogenic activities including pollution from homes, companies, power plants, and car vehicles, which result in the release of molecules like Carbon dioxide, Nitric dioxide, and Sulfur dioxide, are making it more and more acidic. The screen house experiment was undertaken to assess how acid rain affects plants. In the lab, to create acid rain concentrated sulphuric acid (H2SO4) and concentrated nitric acid (HNO3) were mixed in a 2:1 ratio. The desired pH level was measured using a Duplex pH meter. The plant was simulated with acid rain (pH 2.5, 3.0, 3.5, and control 5.6) every three days for six weeks. ANOVA was used for the statistical analysis. The significance of the mean difference was assessed using Ducan's multiple-range tests. With increasing pH levels, plant height (FPepper = 63.835), leaf area (FPepper =60.965), stem girth (FPepper =39.3), the number of leaves (FPepper =34.265), relative growth rate (FPepper = 40.646), and chlorophyll content (FPepper = 4.6029, 7.8154, 36.746) decreased considerably (p<0.001). These findings advance our knowledge of how acid rain impacts urbanvegetation and serves as a warning to limit acid rain production

Published: March 2023

Taxonomic identification of algae at both generic and species levels is problematic owing to several reasons including cells’ fragility, sensitivity to chemical fixatives and inconspicuous morphological features. The planktonic algae in tropical African dams have been particularlyproblematic given the paucity of algal taxonomic experts in this region. In this study, we presentfor the first time the taxonomic and geographic appraisal of planktonic Algae at Pindiga Dam. Further, planktonic algal flora and its monthly variations at the Pindiga Dam were investigated. The study revealed a total of 35 genera. Species in the family Chlorophyceae were the most abundant (42%), followed by those in the families Bacillariophyceae (38%) and Charophyceae(25%). Other taxonomic groups present were Chryophyceae, Cryptophyceae, Cynophyceae and Euglenophyta (7%) each. Trachelomonas, Tetrahedrom and Pleurozester were the most abundant taxa. The Important Value Index (IVI) and species diversity of algae are dependent on the sampling month. For instance, Trachelomonas recorded the highest IVI (23.67) and thelowest was recorded by Cryptomonas (8.18) in April, but it was observed that in May; Tetrahedrom recorded the highest IVI (22.57) and the lowest was recorded by Zygnema (9.38). In June, another set of taxa recorded the highest and the Lowest IVI namely: Pleurogaster, Crucigenia (17.63) and Netrium, Oedogenium (8.93) each.

Refractive error is caused by an error in the refractive power of the eye due to alteration in the ocular length. Uncorrected Refractive error is the second leading cause of visual impairment worldwide. Uncorrected refractive errors are common visual impairment among medical students. The study was designed to determine the prevalence of Refractive error among medicalstudents. A cross-sectional study conducted from October, 2021 – March, 2021 among Medical students. 157 students were selected by simple sampling technique, aged between 17 to 25 years. Demographic data of each student was obtained by a combination of self-administered interviewer questionnaire and clinical eye examination. The history of the past and previous eyecheckup and use of glasses were also determined. Snellen chart, pinhole, pen-torch, ophthalmoscope, retinoscope were used to determine refractive error among the students. The study showed that 14.0% of `the students had visual impairment, and the prevalence of refractive error was found to be 10.8% with a preponderance of myopia at 70.6%, hyperopia at 17.6%, then astigmatism at 11.8%. Out of the students with myopia, 88.2% had low degree myopia. The study shows that 18.2% of the students were not using corrective lenses. Refractive error is a significant cause of visual impairment and regular eye screening is necessary for early detection and correction of refractive errors among medical students.

Hydro-Turbine Coordination Power Predictive Method of Improved Multi-Layer Neural Network Considered Adaptive Anti-Normalisation Strategy
Authors: Kong Fannie , Xia Jiahui , Yang Daliang , Lan Tianshun
Published: March 2023

Due to the limitation of economics and time cost, the data obtained from hydro-turbine coordination field test are insufficient to fully guide the setting of unit operating parameters. To enlarge the amount of data, realise power point tracking, and avoid the problems of high non-linearity with hydro-turbine physical model which is difficult to simulate in actual field, a mathematical prediction model is proposed based on an improved multi-layer neural network. Using the rule activation function, L2 regularisation, Adam optimiser and its gradient parameters are optimised by PSO algorithm in the prediction model. It is found that lacking true value in the process of anti-normalisation leads to difficulty for actual forecast of neural network. Therefore, an adaptive anti-normalisation strategy is proposed to improve the actual prediction accuracy, which can judge the value of the interval. According to the analysis of examples with hydro-turbine coordination and non-coordination test, the results show that the proposed prediction model and interval strategy can effectively forecast the coordination operating conditions of the turbine with high accuracy under small samples.
Analysis and Implementation of Switched Capacitor-based Multi-Level Inverter for Electric Vehicles Applications
Authors: Manivel Murugesan , Kaliappan Lakshmi
Published: March 2023

Significant interest has been shown in switched capacitor (SC)-based multi-level inverters (MLIs), which decrease the need for a DC supply and enhance power quality. The common issues with SC-MLIs include an uneven distribution of conducting paths, increased voltage drop across capacitors, the sum of all inverter DC link voltages across the highest voltage rated switches, and a higher total standing voltage (TSV). The purpose of this paper is to create a SC-MLI with less components in order to maintain a constant voltage across the capacitors, to obtain higher voltage gain with fewer parts, fewer conducting routes, lower TSV, and to create a more affordable and effective inverter. The structure of the MLI is created by a cascade interconnection between the number of SC cells. A single input multiple output (SIMO) converter boosts the DC-link voltage over the stable DC voltage of the solar panels using a modified perturb and observe (P&O) method. Additionally, fewer switches in the conduction path and 50 % of the switches operating at normal frequency guarantee a decrease in an overall loss of power in the proposed network. The benefits of the recommended MLI are made clear by comparing them with 17-level MLIs in terms of the number of elements, stress, gain, and cost factor. Detailed experimental results are shown under various transient conditions to show that the 17-level prototype is operationally viable. The total harmonic distortion (THD) is found to be identical and is less than 5 %, which meets IEEE standards.
