Authors: Castro Fernando Ferreira de , Peiter Carlos Cesar , Góes Geraldo Sandoval
Published: November 2022

As matérias-primas minerais estão na base de grande parte das atividades econômicas, em algum estágio de suas cadeias produtivas, e a tendência é de que, cada vez mais, estejam nessa posição. Certas matérias-primas minerais apresentam especificidades porque o risco de suprimento e sua importância econômica variam entre os países ou blocos econômicos, e também podem ser atualmente definidas como “críticas”, pelas incertezas em seus mercados, ou “estratégicas”, em face às políticas internas. Tendo em vista a relevância mundial dos bens minerais, o objetivo deste Texto para Discussão é apresentar um panorama atual das diferentes políticas internacionais sobre os minerais críticos e/ou estratégicos adotadas na China, Estados Unidos, União Europeia – principais consumidores mundiais, comparando com a evolução dos estudos e políticas brasileiras até a recente definição da primeira lista de minerais estratégicos do Brasil. Por fim, será sinteticamente abordado o caso do nióbio brasileiro, matéria-prima estratégica para o Brasil e crítica internacionalmente. A metodologia qualitativa adotada parte de extensa revisão bibliográfica e documental no contexto da geopolítica das matérias-primas, a fim de apresentar o panorama dos modelos de avaliação e elaboração das listas de matérias-primas críticas e estratégicas em utilização, apontando assim alternativas metodológicas para orientar as políticas nacionais.
TD 2770 - Avaliação de políticas de redução tarifária dos sistemas de transporte público coletivo no Brasil : evidências empíricas
Authors: Carvalho Carlos Henrique Ribeiro de
Published: November 2022

Os sistemas de transporte público vêm perdendo demanda nos últimos vinte anos na esteira do crescimento do transporte individual motorizado e do aumento real dos preços das tarifas dos sistemas públicos. O problema disso é que os sistemas de mobilidade urbana se tornam cada vez menos sustentáveis em função do aumento das externalidades negativas do transporte, como acidentes com vítimas, poluição e congestionamentos urbanos. À luz das propostas de alteração desse modelo de financiamento com vistas à adoção de políticas de redução do preço das tarifas do transporte público, o texto traz evidências empíricas do benefício econômico, social e operacional dessas políticas pela avaliação do caso da cidade de Fortaleza-CE, que congelou o preço de suas tarifas de transporte durante cinco anos. Utilizando métodos econométricos de avaliação de políticas (controle sintético e diferenças em diferenças), pôde-se verificar que, com o congelamento de preços, houve redução do desemprego nas camadas de renda mais baixas e maior uso do transporte público em detrimento do transporte individual, o que tornou o sistema de mobilidade mais sustentável.

Dados sobre características sociodemográficas da população brasileira e de localização de empregos e serviços públicos nas cidades do país são fundamentais para o desenvolvimento de diversas pesquisas e políticas públicas. No entanto, esses dados no Brasil muitas vezes são de difícil acesso, ou são disponibilizados em resoluções espaciais conflitantes, e exigem uma grande capacidade computacional para seu processamento adequado. Este texto para discussão apresenta a base de dados sociodemográficos e uso do solo criada no Projeto Acesso a Oportunidades, bem como descreve os métodos utilizados em seu desenvolvimento. A base de dados consiste em uma grade de hexágonos de alta resolução (área 0.11 km2) que agrega as informações sobre a distribuição espacial da população (segundo idade, sexo, renda, cor/raça), de empregos e de serviços públicos, como escolas (nível infantil, fundamental e médio), estabelecimentos de saúde (serviços hospitalares e ambulatoriais de baixa, média e alta complexidade) e centros de referência de assistência social (Cras). Nesta versão, a base de dados traz essas informações para as maiores cidades do Brasil. Esta base é publicamente disponibilizada pelo Ipea pelo site do Projeto Acesso a Oportunidades e por meio do pacote de R aopdata. Espera-se que este trabalho facilite que pesquisadores e gestores públicos possam mais facilmente acessar e utilizar dados de alta qualidade nos processos de tomada de decisões de planejamento e política públicas.
TD 2779 - Tributação e inovação : uma revisão da literatura
Authors: De Negri Fernanda
Published: November 2022

O debate sobre a reforma tributária, nos meios acadêmicos e políticos brasileiros, contempla inúmeros problemas do nosso sistema tributário, visando simplificá-lo e aumentar sua eficiência e sua progressividade, a fim de se garantir a capacidade do Estado de fornecer serviços públicos essenciais. Uma dimensão relevante, contudo, tem passado ao largo desse debate: até que ponto a estrutura de tributação pode induzir ou restringir a inovação, a geração de novos negócios e o dinamismo do sistema produtivo nacional? Este texto procura incorporar essa dimensão a um debate já complexo e cheio de nuances. Para tanto, apresenta uma revisão não sistemática da literatura empírica internacional sobre os efeitos da tributação nos investimentos em pesquisa e desenvolvimento (P&D) e na inovação, em seus diversos aspectos. São apresentados resultados de estudos recentes que tratam, entre outros temas, do impacto dos impostos sobre o investimento em P&D e em ativos de risco e sobre o empreendedorismo. Também são apresentados estudos sobre como a estrutura tributária pode afetar preços relativos e, assim, incentivar a adoção e a difusão de novas tecnologias, tais como as ambientais, além de análises sobre os incentivos fiscais para P&D.
Modeling the Impact of Pandemic-Induced Shocks and Support Measures with an Emerging Market Economy
Authors: Parvez Md. Al-Amin , Shaeba Mashrura Kabir , Hossain Md. Sajjad , Katha Evanta Hashem
Published: November 2022

Purpose: This paper analyzes the impacts of COVID-19 shocks on an emerging market economy using a Graphical User Interface (GUI) model.
Methods: Event study analysis has been adopted using secondary data for measuring the impacts and impulse responses of different shocks.
Results:  The paper shows how the shocks affect the economy using graphical presentations of impulse responses of major macroeconomic indicators. The shapes and movements of the impulse response curves indicate how the effects pass through from one sector to another; how long the effects may persist in the economy, and how much time will be required for recovery. All these simulations suggest that immediate supportive measures from both fiscal and monetary sides help recover the economy, although marginally due to the required higher costs stemming mainly from the higher exchange rate volatility.
Implications: Several policy implications such as sector-specific support measures, prioritization of sectors, rationing of credit facilities, efficient exchange rate management, etc., can be followed by the countries regarding fiscal and monetary policy measures towards reducing COVID-19-induced similar shocks.

Dampak Pluralisme terhadap Penyampaian Amanat Agung di Era Digital
Authors: Epan Yovianus , Naftali Sandi , Putra Yulius Subari , Prananto Prananto , Widjaja Fransiskus Irwan
Published: November 2022

Dalam dunia pluralis, kekristenan dihadapkan pada tantangan yang serius, pluralis menerapkan keharmonisan dalam keberagaman untuk menciptakan kedamaian. Setiap orang merasa perlu terbuka terhadap agama, suku, dan budaya. Hal ini juga berarti bahwa setiap orang juga bebas menjalankan kebenaran yang diyakininya. Dampaknya setiap orang bebas menjalankan agamanya masing-masing tanpa ada intervensi dari agama maupun kelompok lain, dan ini menyebabkan setiap agama tidak dapat menjalankan ekspansi jiwa-jiwa dengan bebas untuk menjadi pengikutnya meskipun pluralisme memiliki cara untuk membicarakan agama melalui cara berdialog. Hal ini juga berdampak bagi penyampaian amanat agung yang menjadi terbatas sehingga orang percaya tidak termotivasi lagi dalam menyampaiakn kabar baik karena adanya dampak pluralisme. Namun, tidak dapat dipungkiri bahwa teknologi informasi dan komunikasi juga memberikan peluang bagi pemberitaan kabar baik di tengah masyarakat pluralis (sosial media). Adapun kebaruan yang ditawaran dalam penelitian ini juga berpangakal dari penelitan sebelumnya, seperti yang dikemukakan oleh Fransiskus Irwan Widjaja menandaskan bahwa kelompok agama perlu melihat kambali tanggung jawabnya agar dapat berkerja sama, dan bertindak sebagai distributor rahmat Tuhan dalam eskalasi keharmonisan dan kedamaian agama-agama. Selaras juga dengan apa yang ditulis oleh Y. Hariprabowo dalam kesimpulan yang paparkan dalam penelitiannya bahwa dialog merupakan unsur dasar dalam misi evangelikal, yang memperkenalkan nilai-nilai dari Injil. Kedua penelitian tersebut sudah mengemukakan dampak pluralisme dan penyampaian amanat agung sehingga penulisan ini menawarkan dampak plurlisme terhadap penyampaian amanat agung era digital. Data-data yang diperoleh diharapkan dapat membantu orang percaya untuk mengambil celah pemberitaan injil di era digital.Kata Kunci: Pluralisme; Amanat Agung; dan Era Digital
Simulating Reflected Light Coronagraphy of Earth-like Exoplanets with a Large IR/O/UV Space Telescope: Impact and Calibration of Smooth Exozodiacal Dust

Published: November 2022

Observing Earth-like exoplanets orbiting within the habitable zone of Sun-like stars and studying their atmospheres in reflected starlight requires contrasts of ∼1e–10 in the visible. At such high contrast, starlight reflected by exozodiacal dust is expected to be a significant source of contamination. Here, we present high-fidelity simulations of coronagraphic observations of a synthetic solar system located at a distance of 10 pc and observed with a 12 m and an 8 m circumscribed aperture diameter space telescope operating at 500 nm wavelength. We explore different techniques to subtract the exozodi and stellar speckles from the simulated images in the face-on, the 30 deg inclined, and the 60 deg inclined case and quantify the remaining systematic noise as a function of the exozodiacal dust level of the system. We find that in the face-on case, the exozodi can be subtracted down to the photon noise limit for exozodi levels up to ∼1000 zodi using a simple toy model for the exozodiacal disk, whereas in the 60 deg inclined case this only works up to ∼50 zodi. We also investigate the impact of larger wave front errors and larger system distance, finding that while the former has no significant impact, the latter has a strong (negative) impact. Ultimately, we derive a penalty factor as a function of the exozodi level and system inclination that should be considered in exoplanet yield studies as a realistic estimate for the excess systematic noise from the exozodi.

Determination of stoichiometry deviation in wide-band II–VI semiconductors on the basis of equilibrium vapor phase composition
Authors: Kobeleva Svetlana P.
Published: November 2022

A method has been suggested for determining stoichiometry deviation in cadmium and zinc chalcogenides based on the temperature dependence of the ratio of components partial pressures during evaporation of solid compounds in a limited volume. The new method differs from methods implying the collection of excessive component during evaporation in large volumes. The method includes measuring the partial pressures of vapor phase components during material heating to above 800 K, solving a set of material balance equations and the electric neutrality equation, and calculating the stoichiometry deviation in the initial compound at room temperature. Intrinsic point defect concentrations are calculated using the method of quasichemical reactions. The independent variables in the set of material balance equations are the sought stoichiometry deviation, the partial pressure of the metal and the concentration of free electrons. We show that the parameter of the material balance equation which determines the method’s sensitivity to stoichiometry deviation, i.e., the volume ratio of vapor and solid phases, can be considered constant during heating and evaporation if this parameter does not exceed 50. If the partial pressure is measured based on the optical density of the vapors, then the sensitivity of the method can be increased to not worse than 10–6 at.%.

Authors: Lee Joondon , Kim Jinseok , Ghang Byeongzu , Jeong Wooseong
Published: November 2022

Background/Aims: The occurrence of gout attacks at the start of uric acid lowering treatment worsens compliance. We aimed to determine the appropriate dose of febuxostat to reduce the occurrence of gout attacks during the initial treatment period. Methods: We retrospectively analyzed the data of patients diagnosed with gout who underwent treatment at Jeju National University Hospital between May 2018 and May 2020. Results: Two-hundred and twenty-seven patients were included, with a mean age of 53.2 ± 16.4 years, and 219 (96.5%) were male. The patients were divided into two groups according to the starting dose of febuxostat (20 mg vs. 40 mg). There were no significant differences in mean age, disease duration, colchicine, estimated glomerular filtration rate (eGFR), initial uric acid levels, and presence of subcutaneous tophi between the two groups. Gout attacks occurred more frequently in the 20 mg group than in the 40 mg group during the first 3 months of treatment (32.0% vs. 14.3%, p = 0.002), particularly during the first month (21.3% vs. 7.5%, p = 0.005). Multivariate logistic regression analysis was conducted adjusting for the effects of disease duration, the presence of subcutaneous tophi, eGFR, and initial uric acid levels. A febuxostat starting dose of 40 mg (odds ratio, 0.464; 95% confidence interval [CI], 0.246 to 0.862; p = 0.015) and anti-inflammatory prophylaxis (odds ratio, 0.359; 95% CI, 0.158 to 0.813; p = 0.014) were found to be independent factors associated with a gout attack. Conclusions: Starting uric acid lowering treatment with febuxostat 40 mg rather than 20 mg may reduce the incidence of gout attacks in the early period of treatment in Korean patients with gout.
Processus en thérapie familiale psychanalytique : mise à l’épreuve et ré-étayage
Authors: Knéra-Renaud Laurence
Published: November 2022

À partir de l’exemple d’une thérapie familiale psychanalytique, l’auteure propose de montrer l’utilité de ce type de thérapie ainsi que des aspects spécifiques de son processus thérapeutique grâce à la contenance, au ré-étayage, à l’interassociativité et au contretransfert. Cette thérapie d’une famille marquée par un deuil récent, les vécus traumatiques ou encore les disputes, a traversé le confinement. Celui-ci a pu jouer un rôle dans l’évolution du processus thérapeutique, en favorisant l’élaboration d’éprouvés de tristesse. Ce processus évolutif de la thérapie a également permis l’expression et la progressive transformation de vécus traumatiques plus anciens. L’émergence mythopoïétique qui a succédé au confinement est un moment majeur du processus thérapeutique, pourvoyeur de libido et de représentations, alimentant le corps psychique familial.
L’expérience traumatique et son « souvenir hybride »
Authors: Lebon Cristelle
Published: November 2022

L’auteur introduit la notion de souvenir hybride : une forme de symbolisation primaire en thérapie familiale psychanalytique. Il s’agit, par la réactivation hallucinatoire des traces perceptives d’une expérience familiale traumatique, d’une tentative groupale de re-présentation d’une scène, dans laquelle se mêlent les registres de l’archaïque, du primaire et du secondaire. L’émergence d’un souvenir hybride se perçoit par le changement de tonalité et les réactions de défenses familiales ; elle confronte le néo-groupe à une double urgence paradoxale : symboliser et ne pas représenter. Le thérapeute, pris dans cette double contrainte, soutient les efforts de symbolisation du groupe familial tout en respectant ses défenses, avec lesquelles il est lui-même aux prises. Le souvenir hybride produit un ébranlement dans la thérapie, initiant la symbolisation d’une expérience traumatique qui, au fil des séances, se traduit dans des formes représentationnelles secondarisées.

Published: November 2022

The regenerative braking in the tram allows the energy to be returned to the power grid through a power inverter. Since the inverter location between the tram and the power grid is not fixed, resulting in a wide variety of impedance networks at grid coupling points, posing a severe threat to the stable operation of the grid-tied inverter (GTI). By independently changing the loop characteristics of the GTI, the adaptive fuzzy PI controller (AFPIC) can adjust according to different impedance network parameters. It is challenging to fulfill the stability margin requirements of GTI under high network impedance since the PI controller has phase lag characteristics. A correction method of series virtual impedance is proposed, which connects the inductive link in a series configuration with the inverter output impedance, correcting the inverter equivalent output impedance from resistance-capacitance to resistance-inductance and improving the system stability margin. Feedforward control is adopted to improve the system's gain in the low-frequency band. Finally, the specific series impedance parameters are obtained by determining the maximum network impedance and setting the minimum phase margin of 45°. The realization of virtual impedance is simulated by conversion to an equivalent control block diagram, and the effectiveness and feasibility of the proposed method are verified by simulation and a 1 kW experimental prototype.

Published: November 2022

Carotid total plaque area (TPA) is an important contributing measurement to the evaluation of stroke risk. Deep learning provides an efficient method for ultrasound carotid plaque segmentation and TPA quantification. However, high performance of deep learning requires datasets with many labeled images for training, which is very labor-intensive. Thus, we propose an image reconstruction-based self-supervised learning algorithm (IR-SSL) for carotid plaque segmentation when few labeled images are available. IR-SSL consists of pre-trained and downstream segmentation tasks. The pre-trained task learns region-wise representations with local consistency by reconstructing plaque images from randomly partitioned and disordered images. The pre-trained model is then transferred to the segmentation network as the initial parameters in the downstream task. IR-SSL was implemented with two networks, UNet++ and U-Net, and evaluated on two independent datasets of 510 carotid ultrasound images from 144 subjects at SPARC (London, Canada) and 638 images from 479 subjects at Zhongnan hospital (Wuhan, China). Compared to the baseline networks, IR-SSL improved the segmentation performance when trained on few labeled images (n = 10, 30, 50 and 100 subjects). For 44 SPARC subjects, IR-SSL yielded Dice-similarity-coefficients (DSC) of 80.14–88.84%, and algorithm TPAs were strongly correlated ($ r = 0.962 - 0.993 $, $ p $ < 0.001) with manual results. The models trained on the SPARC images but applied to the Zhongnan dataset without retraining achieved DSCs of 80.61–88.18% and strong correlation with manual segmentation ($ r = 0.852 - 0.978 $, $ p $ < 0.001). These results suggest that IR-SSL could improve deep learning when trained on small labeled datasets, making it useful for monitoring carotid plaque progression/regression in clinical use and trials.

The major aim of DG optimal placement is obtaining the best DGs units sizes and locations so as to have optimum operation and planning of the distribution network system while considering DG capacity constraint. This paper addresses the issues related to the improvement of voltage profile and power loss reduction by integrating DG units. The technique was applied to optimally placed optimum DG unit size in distribution systems for the improvement of candidate bus voltage and reduction of power loss in the system. The technique proposed was simulated on IEEE-10 bus and IEEE-13 bus standard test system, and the obtained results show that the proposed method is strong and effective for optimal placement of DG units.
Knowledge, attitudes and practices (KAP) regarding refractive errors among medical undergraduates in Colombo district: A descriptive study
Authors: Dissanayake M.M. , Kiritharan A. , Dissanayake P.H.
Published: November 2022

Methods: This descriptive cross-sectional study was conducted from June to August 2019 among 255 medical undergraduates. After obtaining the ethics approval, the pretested questionnaire was distributed via google forms. The responses were analyzed using standard statistical software. Results: The data was collected from 255 (59.7%) students, with age ranging from 20-29 years (mean 23.5 years), females represented 70%, of the total study population. 25% were from final year and 17% were studying in the first year. Most of the respondents (87%) were familiar with the term refractive errors. However only 51% were able to describe the basic types of refractive errors accurately. 46% believed prolonged usage of corrective lens would lead to dependence. 7% said they didn’t know that eyes had to be checked regardless of eye diseases. Recent advances in refractive error correction such as lasik surgery was known to only 55% and 3% thought there is no treatment option for refractive errors. Discussion and conclusion: Majority of medical undergraduates were aware of refractive errors. However, there were many misconceptions on the subject and lapse in knowledge which necessitates regular revision of ophthalmic education in order to cater to the expanding needs of patients in the future.

Retinal arterial occlusions are rarely seen among the young and out of all types of retinal arterial occlusions, the cilio-retinal artery involvement is uncommon as the incidence of cilio-retinal artery is 6.9% to 49.5% in population. Hence when a retinal arterial occlusion is seen in a young patient, the cause for it is to be investigated. This case report focuses on an instance where an embolic phenomenon caused by infective endocarditis leading to retinal arterial occlusion.

Background: Patients presenting with corneal pathology and cataract present a surgical challenge to the operating surgeon. Some Ophthalmologists prefer to perform combined keratoplasty and cataract surgery simultaneously, while some prefer to perform sequentially. Purpose: To describe performing deep anterior lamellar keratoplasty and phacoemulsification surgery on two patients with corneal opacity and cataract. Setting: National Eye Hospital, Colombo Methodology: We report two patients who underwent Deep Anterior Lamellar Keratoplasty (DALK) and cataract surgery.The first patient was a 66-year male patient. He had hand movement vision in both eyes. The right eye had diffuse corneal haze (corneal depositions) and a white mature cataract. The left eye also had corneal haze and a mature cataract. The fundi could not be visualized but the B scan showed an attached retina. The intra-ocular pressure of both eyes were normal.The second patient was a 54-year female with right eye 6/60 due to diffuse corneal opacity (old interstitial keratitis) and mature cataract in the right eye. The left eye had a clear cornea and had IOL and the Best corrected visual acuity was 6/6. The fundus of the right eye was poorly visualized, but the B scan showed attached retina and the Intra-ocular pressure was normal.Surgery was performed in the sequence of lamellar keratoplasty followed by phacoemulsification and Intraocular lens implantation and finally completion of corneal deep anterior lamellar keratoplasty with manual dissection. Both patients achieved good visual outcomes over 6 months postoperatively. Conclusion: Corneal pathology with cataracts can be operated on as a simultaneous surgery. However, preoperative planning for surgical surprises and the suitable sequalae of surgical steps, with proper IOL power calculation leads to good visual outcomes.
Visual outcomes in the management of dropped nucleus without using the fragmatome
Authors: Salvin K.A.
Published: November 2022

Background: Phacoemulsification (Phaco) and intraocular lens implantation is the commonest surgical practice for the treatment of cataract. Posterior capsular rupture and dropping the nucleus into the vitreous is one of the less common but sight threating complication of phacoemulsification. Trans pars plana posterior vitrectomy (TPPV), removal of the dropped lens fragments and insertion of an intraocular lens is the preferred treatment option for the above complication. The intraocular lens may be placed in the sulcus where capsular ring is intact or scleral fixation is done in the case of absent capsular ring. Methodology: This study is a retrospective review of patients who had TPPV, removal of the lens fragments through the corneal incision using torsional phaco hand piece and sulcus insertion of multipiece intraocular lens (IOL) as the treatment for dropped lens fragments complicating cataract surgery at Nawaloka Hospitals PLC, Colombo, Sri Lanka. Forty four consecutive patients who underwent TPPV from January 2018 to December 2019 have been studied. The notes on the medical records at the initial presentation, second and eighth week post vitrectomy records were reviewed. Results: Forty four patients were reviewed within the 24-month period. There were 30 (68.2%) males and 14 (31.8%) females. All the patients were operated within a week after phacoemulsification. The best corrected visual acuity was 6/9 or better in 33 (75%) eyes at two weeks and 8 weeks post-surgery. There were no major complications observed in the series. Conclusion: Dropped nucleus following phacoemulsification can be managed by removal of the lens through the corneal incision using phaco handpiece with good visual outcomes.
Comparing surgical outcome between conventional and inverted ILM flap technique for full thickness macular hole repair
Authors: Kumarage C.J. , Danapala M.
Published: November 2022

Introduction: Macular holes are primarily managed surgically; either conventional full-thickness Macular Hole (FTMH) repair or the inverted flap technique. Large macular holes (>than 400 micrometers) have poor surgical outcome, with only 44% closure and inverted flap method has resulted better outcome in visual recovery and a higher closure rate. Objective: To compare surgical outcome (anatomical and functional) between conventional and inverted ILM flap technique in macular hole surgery. Methodology: A prospective randomized clinical trial; a longitudinal study with 2 waves of data collection. 154 Pseudo-phakic clients (50-70 years) with full-thickness large macular hole were randomly selected to 2 groups to undergo either technique by same consultant VR surgeon. The approval of Ethics Committee of the National Eye Hospital was obtained. Results: There is 88.3% closure in conventional group and 96% closure in inverted flap technique. However, no significant difference between 2 groups (p>0.05) in the anatomical success and even when compared sub-categorically with U, V, W closure and non-closure. There was a statistically significant improvement in visual acuity (p=0.002) observed in the inverted flap group, but the improvement observed in visual acuity among CG (p=0.18), the improvement in Snellen Chart reading of both groups (p=0.15) and type of closure and surgical technique (p=.369) were not statistically significant. Conclusion: The overall success of anatomical closure following FTMH repair is significantly better compared to literature (92.2% Vs 44%); but there is no statistically significant difference in anatomical success between the two groups. Both groups had a better functional outcome and a statistically significant improvement seen in the ILM-G and CG group. Recommendations: Being the first such study, data gives promising evidence to support the current surgical practice and assist in service development and training.

Published: November 2022

Objectives: To study the change of corneal astigmatism in patients who had a cataract surgery using a temporal approach and the distribution of corneal astigmatism reference to the axis and magnitude. Methodology: Retrospective analysis of the records of 2700 patients who underwent phacoemulsification surgery at Sri Jayewardenepura General Hospital during the period of May 2011 to May 2019. Pre-operative and one-month postoperative astigmatism obtained using keratometry values. Results: Study population consisted of 2700 patients. Age ranging from 17 years to 94 years. 38% patients were male, and 62% patients were female. Mean preoperative astigmatism calculated was 0.86D. In which 63% of patients had against the rule astigmatism. Mean post-operative astigmatism obtained was 0.84D. Results shows overall reduction in post-operative astigmatism compared to pre-operative by 0.02D though this amount is not statistically significant. However, subgroup analysis of against the rule astigmatism category showed statistically and clinically significant reduction in corneal astigmatism. Conclusion: Phacoemulsification using temporal approach reduce or maintains the pre-existing astigmatism. Specially for patients having against the rule astigmatism.

Background: Patients with acute febrile illness need to be screened for malaria and coronavirus disease 2019 (COVID-19) in malaria-endemic areas to reduce malaria mortality rates and to prevent the transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).Objectives: To estimate the frequency of children and adolescents with COVID-19 and/or malaria among febrile patients attending for malaria diagnosisMethod: This cross-sectional study was conducted in a sentinel site for malaria surveillance during the SARS-CoV-2 pandemic (Omicron variant), from October 2021 to December 2021 in Gabon. All febrile patients were tested for malaria using microscopy. Severe acute respiratory syndrome coronavirus 2 was detected by real time polymerase chain reaction (RT-PCR) and rapid antigen tests developed by Sansure Biotech®.Results: A total of 135 patients were screened. Their median age was 6 (interquartile range [IQR]: 3–14) years. Malaria was confirmed for 49 (36.3%) patients, 29 (32.5%) children, 13 (59.0%) adolescents and 7 (29.2%) adults. The frequency of COVID-19 cases was 7.4% (n = 10/135), and it was comparable between children (n = 6; 6.7%), adolescents (n = 2; 9.1%) and adults (n = 2; 8.3%) (p = 0.17). Malaria and COVID-19 co-infections were diagnosed in 3 (6.1%) patients from all the age groups. Participants with a co-infection had a higher median temperature, a higher median parasitaemia, and were mostly infected with non-falciparum malaria.Conclusion: COVID-19 cases and cases of malaria/COVID-19 co-infections were found in febrile children and adolescents. SARS-CoV-2 testing should be included in the screening of suspected malaria cases.Contribution: This study highlights the presence of malaria-COVID-19 coinfection among children and adolescents who should also be screened for both diseases, like for adults.

Leiomyosarcoma (LMS) is a smooth muscle-derived malignant mesenchymal tumour. Primary LMS arising from the ovarian vein is uncommon. A 51-year-old female presented with left loin pain and was diagnosed with a LMS arising from the gonadal vein. The patient refused any treatment. Early detection and timely diagnosis of retroperitoneal masses will improve the prognosis and survival rate in these patients. CT imaging plays an important role in diagnosis.Contribution: Retroperitoneal leiomyosarcoma of vascular origin is a rare entity. CT plays crucial role in diagnosing them by demonstrating the extent of the tumor along the gonadal vein. Early detection and timely diagnosis of retroperitoneal masses will improve the prognosis and survival rate in these patients.
Use of information and communication technologies in mathematics education lecturers: Implications for preservice teachers
Authors: Dewa Alton , Ndlovu Nokulunga S.
Published: November 2022

The availability and use of educational resources in classrooms has increased remarkably; however, preservice teachers graduate from initial teacher education institutions (ITEIs) and join the profession without the skills for teaching in these new learning environments. This qualitative study was conducted in four South African public ITEIs. It is aimed at examining mathematics lecturers’ integration of information and communication technologies (ICTs) into teaching and its implications for preservice teachers’ readiness to teach in contemporary classrooms. Individual interviews were conducted with 12 mathematics education lecturers and 20 fourth-year students in five focus groups. The findings revealed that whilst the lecturers had some knowledge of how to teach with digital technologies in lecture rooms, they did not model specialised mathematics teaching skills to their students. Informed by activity theory, this study identified institutional gaps in the implementation of digital technologies for teaching. Institutions seemed to view access to technology as sufficient for effective use by lecturers. Initial teacher education institutions should therefore establish and regulate structures that equip and support lecturers with desired ICT pedagogical skills if preservice teachers are to be prepared for the modern classrooms.Transdisciplinarity Contribution: This research contributes to literature on the use of ICTs in Initial Teacher Education. Although it focuses on Mathematics Education, its findings demonstrate the importance of Professional Development if the Scholarship of Teaching and Learning (SoTL) of lecturers in these institutions will adequately prepare preservice teachers for the modern classroom.
